Carl-Henric Svanberg
Chairman

Dear fellow shareholder,
In 2011 we re-laid the foundations of BP. Our objective was to ensure your 
company is able to deliver sustainable shareholder value in the months and years 
ahead. Above all else, this is dependent on BP having the trust of the societies in 
which it works – today and over the long term. 

During the year the board oversaw a major reorganization designed to 
establish a stronger, safer BP. The progress made demonstrates that the company 
can and will recover from the consequences of the Deepwater Horizon accident. 
We remained mindful of the tragic events seen in 2010 and the need to ensure 
such an accident never happens again. 

 I thank you for the patience you have shown as we work to rebuild your 

company.

The board set three priorities for BP. Safety must be enhanced and 

embedded. Trust must be regained. Value must be created through a clear 
strategic plan. While these priorities are simple to express, substantial activity  
is required to turn them into tangible and lasting change.

On safety, the board supported and challenged Bob Dudley and his 

executive team as they restructured and enhanced BP’s processes, systems and 
culture. Furthermore, the board initiated a review of the way BP manages, reports 
and acts on risk, including board oversight.

On trust, we ensured that BP continued to meet its commitments in the 
Gulf of Mexico. We co-operated with every official investigation and prepared 
for litigation. We worked closely with governments and regulators, and we 
communicated openly with shareholders and the wider world.

On value, the board set a 10-point plan focused on growing operating cash 

flow and increasing shareholder returns. The company will play to its greatest 
strengths and prioritize value over volume. Relentless execution of this strategy  
is now needed so we deliver value to our shareholders.

BP’s financial and operating performance in 2011 has created a springboard 

for growth. In the upstream, we secured 55 new exploration licences in nine 

8    BP Annual Report and Form 20-F 2011

countries, and our Refining and Marketing segment delivered very strong 
earnings. Our $38-billion divestment programme is strengthening the group’s 
financial position and focusing our portfolio.  

In 2011 we restored your dividend, and I am pleased to report that we 

increased the dividend by 14% in February 2012, in accordance with our policy.
The wider world did not stand still in 2011. We saw rapid and sometimes 
unpredictable change. This included escalation of the European debt crisis and 
political upheaval in countries where BP has significant operations, such as Libya 
and Egypt. We kept a close watch on these developments and acted where 
required. Our international advisory board assisted us in this task.

The company continually looks for ways to form new relationships and 

enhance its partnerships around the world. Our new alliance with Reliance 
Industries in India is a significant venture in a fast-growing market. Russia is 
particularly important for BP. Our TNK-BP alliance is hugely successful. Since 
acquiring 50% of the company for around $8 billion, BP has received around 
$19 billion in dividends – which equates to around $2 billion per year. In 2011, 
we saw new opportunities in Russia, but these did not progress. This region 
still has excellent potential for BP and we remain committed to it. The nature 
of our industry is rarely straightforward, and BP will never shrink from pursuing 
opportunities simply because they involve challenges.

 In my letter last year, I commented on the evolution of the board. This has 
continued. My goal is to ensure that the board combines a broad set of skills and 
experience. BP’s board should be diverse in the widest sense. It should have 
the best blend of the best people from our industry and from other sectors. BP 
remains committed to meritocracy as well as diversity.

as non-executive directors and Brian Gilvary has joined as an executive director.

Bill Castell has decided not to seek re-election at the forthcoming AGM. Bill 
has made a substantial contribution to the board, not least as chair of the safety, 
ethics and environment assurance committee. Bill has devoted all the time that 
was asked of him and more in the service of the board and the company. I speak 
for the whole board when I thank him sincerely for all he has done. Bill’s role 
as senior independent director will be taken by Andrew Shilston, who will be 
supported on internal matters by Antony Burgmans.

The board committees have always played an important oversight role, 
freeing the main board to concentrate on strategic matters. All of our committees 
have been heavily involved this year. Each committee has dealt with different 
challenges, and all of the directors have been unstinting in the time they have 
given. 

The Gulf of Mexico committee, formed in 2010 and chaired by Ian Davis, 

has been invaluable in allowing the board to prioritize its work during the 
restoration of the Gulf of Mexico and the ensuing litigation. During the year, 
Antony Burgmans became chair of the remuneration committee and Brendan 
Nelson became chair of the audit committee. Paul Anderson took over the chair  
of the safety, ethics and environmental assurance committee in December.

10    BP Annual Report and Form 20-F 2011

During the year, the remuneration committee has worked with Bob Dudley and 
his team to remodel the reward system within the group. The system below 
the board is now clearly focused on the long term and is similar to that used for 
executive directors. I believe our approach to rewarding directors balances the 
company’s priorities of driving financial performance, meeting our responsibilities 
as a corporate citizen and providing value for our shareholders. 

Against all of this background, I have been keen to see how the board 
could work more effectively. During the year, a working group of non-executive 
directors reviewed board tasks, roles and processes. This work, coupled with 
our board evaluation, has led to a number of changes in the way in which the 
board operates. These are set out in the board performance section of this 
annual report.

2011 was a testing year for everyone at the company. The board was 
impressed by the way in which Bob and his executive team tackled a range of 
considerable issues. We were also struck by the tenacity and dedication of BP’s 
employees. On behalf of the board, I thank everyone for their efforts. 

In 2012 we must execute our 10-point plan and continue to meet our 

commitments in the Gulf of Mexico. While many of the investigations into the 
causes of the accident have been completed, we still face major litigation in the 
US during 2012. This must run its course, although we are pleased with the 
continuing progress that we are making with settling some of these claims. 
As part of its strategic role, the board must be mindful of the long-term 

developments in our industry. BP Energy Outlook 2030 tells us that rising 
populations, increasing levels of life expectancy and improving standards of living 
will continue to generate growing demand for energy. The challenges in terms of 
supply are immense. I expect these dynamics to provide BP with opportunities 
for decades to come. The report projects that fossil fuels will be providing around 
80% of the world’s energy in 2030. This will require companies such as ours to 
overcome substantial technical and physical challenges. Lower carbon resources 
and energy efficiency technologies are required to play their part in addressing 
both demand and emissions. BP must understand and adapt to these changes  
in order to remain sustainable in this changing world.

I believe BP ended the year stronger and safer, with increasing forward 

momentum and a clear strategy matched to the world we see ahead. This 
is a great company, with a strong board and excellent people. I thank you for 
your continued support. I will report back to you on BP’s progress at this point 
next year.

Group Chief Executive

14    BP Annual Report and Form 20-F 2011

Dear fellow shareholder,
Following the tragic Deepwater Horizon accident of 2010, BP entered 2011 
facing a range of uncertainties. These included concerns about our ability to 
operate safely in deep water, meet our financial commitments in the Gulf of 
Mexico, and recover the trust and value we had lost. We were also subject 
to intense speculation around the future and direction of the company. 

By the end of the year we had successfully resolved some significant 

uncertainties facing the company. We set new standards for safety, led by our 
safety and operational risk organization, and we reshaped our upstream business. 
We strengthened the group’s financial position by progressing our divestment 
programme. We worked to earn back trust through co-operation with the official 
investigations and actively sharing the lessons learned. We set a clear strategic 
direction through a 10-point plan focused on building value for shareholders. 
We also received permission to resume operations in the Gulf of Mexico – 
a significant milestone. 

During the year more clarity also emerged over the 2010 accident as 
official investigation reports were published. Their central conclusions supported 
that of our own investigation – namely that what happened in the Gulf of Mexico 
was a complex accident involving multiple causes and multiple parties. I am 
pleased that we were able to reach settlements with Mitsui, Weatherford, 
Anadarko and Cameron during 2011. On 3 March 2012 we announced a 
settlement with the Plaintiffs’ Steering Committee, subject to final written 
agreement and court approvals, to resolve the substantial majority of legitimate 
economic loss and medical claims made by individual and business plaintiffs in 
the Multi-District Litigation proceedings pending in New Orleans (MDL 2179). The 
legal process continues with other parties.

We recognize there is a great deal more to do, but I can report that 

BP finished its year of consolidation in robust shape. 

Through the year, BP’s employees worked with great determination to 

enhance what we do and how we do it. This work will continue. I want to 
make it absolutely clear that we are not seeking a return to business as usual. 
The events of 2010 demand more than that. As we move ahead, our job is to 
make BP a stronger, safer company by further embedding safety at the heart 
of the company, continuing to earn back trust, and creating long-term value for 
shareholders once again. In this letter, I outline in more detail the actions taken 
in 2011 to achieve these objectives. 

Safety
During the year, we reorganized our upstream segment to improve clarity and 
accountability. We introduced new systems and technologies to further enhance 
oversight of operations. We continued to increase the capacity of our independent 
safety and operational risk organization, and recruited experts from other high-
hazard industries to add new expertise and perspectives. We also renewed the 
company’s performance and reward systems, values and code of conduct, which 
require whoever works for BP to put safety first.

At the front line, we shut down platforms and operations to make necessary 

upgrades. We set new, voluntary standards for blowout preventers, which shut 
off the flow of oil in an emergency. We also designed a new type of capping 
stack, which now stands ready for deployment anywhere in the world in the 
event of a leak in deep water. 

Trust
Looking back over events in the Gulf of Mexico, I am proud of how BP responded. 
Just in financial terms, during 2010 and 2011 combined we made a pre-tax cash 
outlay of more than $26 billion to cover oil spill response costs, meet claims 
and litigation expenses, support research, promote tourism and help restore the 
environment. The test of corporate responsibility is whether a company follows  
up its words with actions. I believe we have. And we will continue to do so. 

During the year we were invited to 25 countries to share what we have 

learned in the Gulf. In turn, we have gone out to gain insights from organizations 
in other high-hazard sectors, including NASA, the UK Atomic Energy Authority and 
various naval bodies. We will keep listening to others and applying what we learn.

Value 
As I write this letter, the market value of the company remains significantly 
lower than it was before the incident. Our 10-point plan shows our belief that the 
company can realize improved returns for shareholders. The plan sets out what 
you can expect from us, and what you will be able to measure, over the next 
three years.

The plan makes a greater priority of creating value for the shareholder, rather than 
simply increasing production volume. We will sell assets earlier in their lifecycle 
following discovery if we spot opportunities to reinvest in higher growth areas. We 
are also being selective in where we invest along the supply chain. For example, 
we are selling certain mature fields that hold more value for others, and we are 
selling a number of refining and marketing assets that do not match our aspirations.

I want to say a little more about the areas of strength at the heart of 

our strategy. 

Exploration is our lifeblood. We had a record year for new access in 
2011, gaining 55 exploration licences in nine countries. This opened up around 
315,000km2 for exploration. We intend to more than double exploration 
investment over the next three years. 

In deep water, we are confident in our ability to design, engineer and operate 

large installations safely. 2012 will be a busy year for us in the deepwater regions 
of Angola, Brazil and the Gulf of Mexico.

Left New investment 
announced in 2011 may

Clair field of the UK North 
Sea to 2050.

Right February 2011 
saw BP announce a 
partnership with Reliance 
Industries spanning the 
gas value chain in India, 
from exploration to 
marketing.

In giant fields, work with our partners has increased output at Iraq’s 

Rumaila field by more than 10%. BP was the first supermajor to exceed its 
production target in Iraq. During the year we also announced we will be investing 
approximately $14 billion – with our partners – in the UK North Sea. 

Natural gas is set to be the fastest-growing fossil fuel globally to 2030. 

Here, we are forging new partnerships, such as the strategic alliance created in 
2011 with Reliance Industries in India. We continue to have a significant focus 
on developing unconventional resources around the world. Taking technology 
and skills developed in North America, we are working with the governments of 
Oman and Algeria to develop their large tight gas reservoirs, and we also continue 
to work in Indonesia to develop their onshore coalbed methane fields.

We also have exceptional expertise in building supply chains. For example, 

we move gas from 6,000 metres below the Shah Deniz field in Azerbaijan to 
markets in Western Europe, 3,000 kilometres away.

16    BP Annual Report and Form 20-F 2011

In Refining and Marketing, our world-class fuels, lubricants and petrochemicals 
businesses are shifting the balance of their activity towards higher growth 
markets, including China and India. We are moving forward with our plans to sell 
around half of our refining capacity in the US, and we have made good progress 
on the modernization of the Whiting refinery. Looking ahead, we expect our 
downstream operations to be a material contributor to the cash flow we anticipate 
over the next few years.

These strengths are supported by our long-standing track record in 
developing and applying leading technology, and the deep and enduring 
relationships we form. We were disappointed that our exploration plans with 
Rosneft did not progress, but we remain committed to our TNK-BP investment  
in Russia, which continues to be successful. 

A well-balanced business
As the BP Energy Outlook 2030 shows, the world is now in a long wavelength 
transition to a lower-carbon energy mix. For BP, that means helping to meet 
current demand through the supply of oil and gas – including unconventional 
resources – while developing a number of the lower-carbon options needed at 
scale tomorrow. 

During 2011, we invested a further $1.6 billion in our Alternative Energy 
business, which takes total investment since 2005 to $6.6 billion. We have a 
growing biofuels business in Brazil and we added 401MWa of wind generation 
capacity during the year, with interests in more than 1,000 wind turbines now 
turning across the US. In contrast, solar has evolved into a low-margin commodity 
market, and in 2011 we began winding down our remaining solar operations as 
we prepare to exit the business. 

Looking ahead
BP is meeting its commitments and moving forward with increasing momentum. 
2012 will be a year of milestone delivery, with financial momentum building in 
2013 and 2014. In 2012, you can expect high-margin production coming back on 
stream, major project start-ups and new exploration wells, further progress on 
our divestment programme, continued improvement in downstream financial 
performance and completion of payments into the Deepwater Horizon Oil Spill 
Trust fund.

The company has a strong leadership team and non-executive directors 

who provide rigorous oversight – challenging and supporting executives as 
circumstances dictate. I want to thank BP’s employees for their resilience. They 
were again tested hard this year. The character of BP’s people was evident 
wherever we operate, not least in Egypt and Libya, where our teams evacuated 
colleagues and their families safely during the upheavals in the region. 

I thank investors for their continued patience through a tough time. One by 

one, we are addressing the uncertainties facing our company. The days ahead 
may bring further challenges, but we are in a much stronger position than this 
time last year. There is a great deal more to do, but we are building a stronger, 
safer BP that can play an important role in the world for many years to come.

In 2011, energy markets proved resilient, with 
continued growth despite volatile conditions in the 
global economy.

Right Operations

platform. BP 
production in 
Azerbaijan is an 
important source of 
natural gas for markets 
in Western Europe.

The growth in world oil consumption slowed in 2011, albeit with continued robust 
growth in China and certain other non-OECD countries partially offsetting an 
overall decline in OECD countries. However, despite the slowdown in demand, 
average crude oil prices in 2011 were significantly higher than in the previous year, 
exceeding $100 per barrel for the first time (in nominal terms). Natural gas prices 
diverged globally in 2011. Globally, refining margins improved on average as oil 
product demand continued to grow.

Economic context 
After a very strong 2010, world economic growth slowed in 2011 and we expect 
subdued global growth to continue in 2012. Emerging economies with stronger 
productivity and rising populations led by China and India are set to drive growth, 
while developed countries may lag behind as they seek to address their internal 
fiscal imbalances.

Energy demand, and in particular oil demand, has followed overall economic 

trends in recent years, recovering strongly in 2010 but facing more challenging 
conditions in 2011, especially in OECD markets.

Concerns about the volatility of commodity and financial markets, energy 
security and climate change have led to continued debate over the appropriate 
role of markets, government regulation and other policy measures that affect the 
supply and consumption of energy. Given the pressures in the sector, we expect 
regulation and taxation of the energy industry and energy users to increase in 
many areas in the future.

18    BP Annual Report and Form 20-F 2011

Crude oil prices 
Crude oil prices, as demonstrated by the industry benchmark of dated Brent for 
the year, averaged $111.26 per barrel in 2011, about 40% above 2010’s average 
of $79.50 per barrel. This represents the highest annual average ever (in nominal 
terms), as well as the largest one-year increase ever.

Prices rose early in 2011 and then increased further following the loss of 
Libyan supplies, which drove prices briefly above $125 per barrel in April. Thereafter, 
weakening global economic growth, increased production by other OPEC producers 
and the release of International Energy Agency (IEA) strategic stocks helped to 
cushion the disruption. While oil prices eased over the remainder of the year, they 
still ended the year above $100 per barrel.

These record prices prevailed despite the fact that the growth in global oil 

consumption slowed in 2011 with demand rising by roughly 0.7 million barrels per 
day for the year (0.8%)a in the face of slower economic growth and higher prices. 
Growth in 2011 was concentrated in non-OECD countries, led by China. There was 
relatively little change in non-OPEC production and, with the loss of Libyan supplies 
beginning in February, OPEC crude oil production did not return to its January peak 
until November. As a result, by mid-year OECD commercial oil inventories were 
consistently below average for the first time since 2008.

By comparison, global oil consumption in 2010 grew by roughly 2.7 million 
barrels per day (3.1%)b, the strongest growth in annual consumption since 2004, 
driven by a renewed global economy. Crude oil prices in 2010 remained stable in a 
range of $70-80 per barrel before beginning to increase in the fourth quarter due to 
rising consumption and continuing OPEC production.

We expect oil price movements in 2012 to continue to be driven by the pace 
of global economic growth and its resulting implications for oil consumption, and by 
OPEC production decisions, especially in reaction to the recovery of Libyan supplies 
and the EU embargo on Iranian crude.

deepwater Gulf of 
Mexico. BP is one of 
the largest producers 
of hydrocarbons in  
the region.

Natural gas prices 
Natural gas prices diverged globally in 2011, reflecting different regional dynamics. 
The average US Henry Hub First of Month Index fell to $4.04/mmBtu, 8% lower 
than the prices in 2010, while in Europe prices increased.

After a record increase in 2010, global gas consumption growth moderated 

in 2011. In the US, economic momentum supported gas use in the first half of 
the year and a hot summer raised demand. Yet domestic production outpaced 
consumption growth due to further increases in the availability of shale gas. 
Henry Hub gas prices fell and traded below coal parity in US power generation 
throughout the year, leading to the displacement of coal by gas. Unusually mild 
winter weather weakened prices at the end of year. The differentials of production 
area prices to Henry Hub prices continued to narrow as pipeline bottlenecks were 
reduced.

In Europe, spot gas prices at the UK National Balancing Point increased 
by 33% to an average of 56.33 pence per therm for 2011 – the highest level 
since 2008. The loss of Libyan gas supply raised continental European demand 
for Russian gas in early 2011, but LNG supply and weak general demand kept 
spot gas prices below oil-indexed contract levels. Competition between spot 
and contract pipeline supplies continued. High volumes of LNG were available 
to Europe, despite the Japanese earthquake and tsunami in March 2011, which 
caused major nuclear outages and significantly increased LNG purchases in 
Japan. This contributed to a tightening global LNG market over the year.

The economic rebound had led the average Henry Hub First of Month Index 

to recover in 2010 from eight-year lows, rising by 10% to $4.39/mmBtu. In the 
UK, National Balancing Point prices averaged 42.45 pence per therm in 2010 – 
38% above the depressed prices in 2009.

In 2012, we expect gas markets to continue to be driven by the economy, 

weather, domestic production, LNG supply and reductions in nuclear power 
generation following the Fukushima disaster in Japan in March 2011.

Refining margins 
In 2011, demand for oil products continued to grow, albeit more slowly than 
a year ago, with all of the demand increase occurring in non-OECD markets 
and with overall demand in the OECD resuming its structural decline. As new 
refining capacity continued to be commissioned in Asia and the Far East, global 
refinery utilization rates fell in 2011. Despite this, a number of factors supported an 
increase in refining margins across all regions for a second consecutive year. The 
BP refining marker margin (RMM)a averaged $11.64 per barrel in 2011, compared 
with $10.02 per barrel in 2010 and $9.19 per barrel in 2009.

In 2011, diesel prices relative to crude reached highs not seen since 2008 
as the trend to lower-sulphur fuels continued and demand grew. Gasoline prices 
were volatile in 2011. In the US, short-term supply issues supported gasoline 
prices in the middle of the year despite a reduction in demand compared with last 
year. By the fourth quarter, US gasoline prices relative to crude had fallen to the 
lowest levels seen for at least 23 years. Refining margins improved in Asia Pacific, 
due to continuing oil demand growth and the disruption to Japanese refining 
operations caused by the earthquake and tsunami.

US mid-continent crude oils (including the key marker grade of West Texas 
Intermediate) were heavily discounted throughout the year because of increasing 
production in the US Lower 48 states and in Canada, coupled with constrained 
logistics. This allowed refiners that are able to access these crudes to capture 
additional margins. 

The loss of Libyan crude oil supply in the first quarter of 2011 and production 

problems in the North Sea during the summer resulted in record high prices for 
low-sulphur grades of crude oil. This adversely impacted the margin for refiners 
configured to process these grades, particularly in Europe, the US East Coast and 
Asia.

By contrast, in 2010 the RMM increase compared with 2009 was due to 
strongly-improved demand for oil products, in line with the economic bounce-back 
from recession, despite unused refining capacity.

Looking ahead, the overall economic environment is expected to result in 

limited demand growth such that refinery utilization levels are likely to remain low, 
despite the announced shutdown of capacity in Europe and the US.

Business review: Group overviewOur market: Longer-term outlook

The long-term outlook is one of growing demand 
for energy and increasing challenges for our 
industry in meeting the world’s needs.

Long-term growth in energy demand 
Energy demand is linked to economic growth, development and population.  
The world’s population is projected to increase by 1.4 billion over the next  
20 years, while its real income is likely to grow by 100% over the same period. 
This combination of factors is expected to increase world primary energy 
consumption by approximately 40% over the next 20 years, with non-OECD 
energy consumption as much as 70% higher by 2030. Energy and climate 
policies, efficiency gains and a long-term structural shift in fast-growing 
economies away from industry towards less energy-intensive activities may act  
to restrain consumption, but the overall trend is likely to be one of strong growth in 
energy demand.

Oil and gas are still expected to play a significant part in meeting this 
demand and we project they will represent 53% of total energy consumption 
in 2030 (compared with 57% in 2010). Even under the IEA’s most challenging 
climate policy scenario (450 Scenario) that might with difficulty still be achievable, 
oil and gas together still makes up 49% of the energy mix in 2030, with combined 
demand projected to exceed current levels.a The 450 Scenario assumes 
governments adopt commitments to limit the long-term concentration of 
greenhouse gases in the atmosphere to 450 parts-per-million of CO2 equivalent. 
We believe the political, technological, logistical, infrastructure and cost challenges 
presented by the 450 Scenario make it increasingly unlikely to occur, meaning that 
demand for fossil fuels would remain at a higher level for longer.

We also expect advances in technology to lead to new and more efficient 
ways to transform base hydrocarbons (including natural gas and coal) into usable 
forms of energy, petrochemicals and lubricants.

Beyond 2030, we believe it is currently very difficult to provide meaningful 

projections. We expect that growing population and per-capita incomes will 
continue to drive growing demand for the services that energy provides – 
including mobility, heat and light. The way those services are provided will be 
shaped by future technology developments, changes in tastes, and future policy 
choices – all of which are inherently uncertain. Concerns about affordability, 
energy security and environmental impacts – in particular climate change – are all 
likely to be important considerations for the future. These factors may accelerate 
the trend towards more diverse sources of energy supply, a lower average 
carbon footprint, increased efficiency of energy provision and use, and demand 
management.

We actively monitor developments and continually assess a range of 

potential outcomes and their implications for our long-term strategy.

LNG facility in Trinidad, 
where BP has been 
operating since 1961.

Meeting the energy challenge
We estimate that there are enough energy resources available to meet the 
increases in demand. As a measure of this availability, today’s oil reserves could 
meet more than 45 years of demand at current consumption rates; while known 
supplies of natural gas could meet demand for nearly 60 years; and coal could 
meet demand for up to 120 years.a Meanwhile, new technologies are improving 
the availability and affordability of unconventional fossil resources such as shale 
gas, oil sands and coalbed methane. And emerging renewable resources have the 
potential for significant growth as their markets mature and technological advances 
make them more affordable and efficient.

While energy is available to meet demand, action is also required to limit 

the volumes of carbon dioxide and other greenhouse gases being emitted 
through energy use. Global economic challenges have reduced the focus of some 
governments on climate policy, at least in the short term. But the position set 
out at the UN’s 2010 climate change conference in Cancun that deep cuts are 
required to hold global temperature rises to 2˚C, and the commitment by both 
developed and developing countries in Durban in 2011 to negotiate an agreement 
by 2015 that requires action from all countries, suggests that in the medium to 
long term an emphasis on carbon policy will return and grow. We project that 
under known and probable policy and technology, global CO2 emissions may be 
28% higher in 2030 than they are today, partly as a consequence of coal use in 
rapidly-growing economies. More aggressive, but still plausible, energy policy 
and technology deployment could lead to slower growth in CO2 emissions than 
expected, with emissions from energy use falling after 2020, but probably not 
to the extent of putting the world on a global warming trajectory that does not 
exceed 2˚C. And even these policies would require concerted multilateral action 
from policymakers and a willingness by society to bear a significant cost.

Energy security also represents a major challenge. More than half of the 

world’s natural gas is in just three countries, and more than 80% of global oil 
reserves are in 10 countries, most of which are located well away from the hubs 
of energy consumption. The ability and willingness of OPEC members to expand 
capacity and production is one of the main factors determining the dynamics of 
the oil market.

BP Annual Report and Form 20-F 2011    23

Business review: Group overviewOur market: Longer-term outlook

The dual challenges of emissions and energy security underline the value of 
energy efficiency. Increases in efficiency have the potential to reduce emissions 
without inhibiting economic growth, and they can help energy-importing countries 
to reduce their dependency on others. For these reasons, we expect efficiency to 
remain high on the agenda through to 2030.

A diverse energy mix
We believe the global energy challenge can only be met through a diverse mix of 
fuels and technologies. This is why BP’s portfolio includes oil sands, shale gas, 
deepwater production, and alternative energies such as biofuels and wind power, 
in addition to conventional oil and gas. As well as simply meeting growth in overall 
demand, a diverse mix can help to provide enhanced national and global energy 
security while supporting the transition to a lower-carbon economy.

Within the energy mix, we see a key strategic role for natural gas as a lower-

carbon fuel that is increasingly secure and affordable. Used in place of coal for 
power, it can reduce CO2 emissions by half.

Renewables will be essential in addressing the challenges of climate change 

and energy security over the long term. Renewable energy is already the fastest-
growing fuel and is projected to grow 8.2% per annum to 2030 – a rate similar to 
the emergence of nuclear power in the 1970s and 1980s. Renewable energies 
are starting from a low base however, and we project that they are only likely 
to meet around 6% of total energy demand by 2030. With a few exceptions, 
renewables are not yet competitive with conventional power and transportation 
fuels. Sufficient policy support is required to help the commercialization of 
effective options and technologies, but renewables must ultimately become free 
from subsidy and commercially self-sustaining. See Risk factors – climate change 
and carbon pricing on page 60.

The future for hydrocarbons
Given the vital role oil will continue to play in meeting demand, substantial 
investment in new technology will be required to boost recovery from declining 
fields and commercialize currently inaccessible resources. The industry’s ability 
to increase recovery from mature assets will be profoundly important, particularly 
in the world’s giant fields. Over time, it will become increasingly difficult to reach, 
extract and manage oil resources, and companies such as BP may be required 
to move yet further into technically challenging areas. Greater energy intensity 
could be required to extract these resources; operating costs and greenhouse gas 
emissions from operations are likely to increase. Along with increasing supply, we 
believe the energy industry will be required to make hydrocarbons cleaner and 
more efficient to use. 

Carbon capture and storage (CCS) may help to provide a path to cleaner coal 
and gas, but CCS technologies still face significant technical and economic issues 
and are unlikely to be in operation at scale in the near future.

Policy and access
If industry and the market are to meet the world’s growing demand for energy in 
a sustainable way, governments must set a stable and enduring framework. As 
part of this, governments will need to provide secure access for exploration and 
development of energy resources, define mutual benefits for resource owners 
and development partners, and establish and maintain an appropriate legal and 
regulatory environment. Within this framework, we believe that the most effective 
means of finding, producing and distributing diverse forms of energy is to foster the 
use of markets that are open and competitive, and in which carbon has a price.

Our organization: Business model

BP’s business model is to create value across 
the entire hydrocarbon value chain. This starts 
with exploration and ends with the supply of 
energy and other products that are fundamental 
to everyday life.

BP is one of the world’s leading integrated oil and gas companies.a Our objective 
is to create value for shareholders and supplies of energy for the world in a safe 
and responsible way. We strive to be a safety leader in our industry, a world-class 
operator, a responsible corporate citizen and a good employer.

At each stage of the hydrocarbon value chain there are opportunities for us 
to create value – both through the successful execution of activities that are core 
to our industry, and through the application of our own distinctive strengths and 
capabilities in performing those activities.

We have two main business segments: Exploration and Production, and 

Refining and Marketing. Through these, our activities are focused on finding, 
developing and producing essential sources of energy, and turning these 
sources into products that people need. We provide our customers with fuel for 
transportation, energy for heat and light, lubricants to keep engines moving, and 
the petrochemicals products used to make everyday items like plastic bottles.

We also invest in renewable energy sources, which we believe will be an 

increasing source of value for BP. Our activities are focused on biofuels and wind. 
These are managed through our Alternative Energy business, which is reported in 
Other businesses and corporate.

Our projects and operations help to generate employment, investment and 

tax revenues in countries and communities around the world. The relationships 
we form with governments, partners, contractors, customers, franchisees and 
suppliers are very important to the success of our business. We are committed to 
being responsible, meeting our obligations, and building long-lasting relationships.

As a global group, our interests and activities are held or operated through 
subsidiaries, branches, joint ventures or associates established in – and subject 
to the laws and regulations of – many different jurisdictions. Our worldwide 
headquarters is in London. The UK is a centre for trading, legal, finance and other 
business functions as well as three of BP’s major global research and technology 
groups. We have well-established operations in Europe, the US, Canada, Russia, 
South America, Australasia, Asia and parts of Africa. Around 61% of the group’s 
fixed assets are located in OECD countries, including around 37% in the US and 
around 18% in Europe.

The significant subsidiaries of the group at 31 December 2011 and the group 

percentage of ordinary share capital (to the nearest whole number) are set out in 
Financial statements – Note 45 on page 251. For information on significant jointly 
controlled entities and associates of the group, see Financial statements – Notes

Value creation in our industry
BP’s core activities are similar to those carried out by other global, integrated, oil 
and gas companies.

First, we acquire the rights to explore for oil and gas. When we are 

successful in finding hydrocarbon resources, we create value by seeking to 
develop them into proved reserves or by selling them on if they do not fit with 
our strategic objectives. We often work with partners to mitigate risk or gain from 
complementary skills. Through disciplined execution of capital projects we then 
develop, extract and sell the resources. The benefits are shared with governments 
and other partners.

We move oil and gas through pipelines and by ship, truck and rail. We use 
our skills and knowledge to find the best routes to deliver supplies to the most 
attractive markets.

We manufacture fuels and products, creating value by seeking to operate a 
high-quality portfolio of well-located assets safely, reliably and efficiently. We use 
our sales and marketing skills to add value to our fuels and other products.

And we also invest in renewable energy sources, with a focus on biofuels 

and wind.

BP’s distinctive capabilities and sources of value
By operating across the full hydrocarbon value chain we believe we can create 
more value for shareholders, as benefits and costs can often be shared by our 
two segments. We can develop shared functional excellence more efficiently 
in areas such as safety and operational risk, environmental and social practices, 
procurement, technology and treasury management.

We have a distinctive integrated supply and trading function, which aims 
to maximize the value of our production while ensuring our refineries are fully 
supplied. We buy and sell at each stage in the value chain to optimize value for 
the group, often selling our own production and buying from elsewhere to satisfy 
demand from our refineries and customers. The function also creates value 
through entrepreneurial trading, where our presence across the major energy 
trading hubs of the world provides access to vital information on the fundamentals 
of markets that are increasingly connected.

We consider our ability to build a wide range of strong, long-term 
relationships to be both a key strength and crucial to our success. We form 
partnerships with national oil companies and our international oil company 
peers. We partner with universities and governments in pursuit of improving the 
technologies available to us, in order to enhance our operations and develop new 
products. We also actively participate in industry bodies such as the American 
Petroleum Institute and the Marine Well Containment Company in the US and the 
Oil Spill Preventions and Response Advisory Group in the UK. Regular review and 
audit processes enable us to maintain strong links with contractors and suppliers. 
We work with our partners through the management frameworks embedded 
in our joint venture and shareholder agreements to ensure safe and reliable 
operations, and for our mutual commercial benefit.

We believe our development and application of technology represents a 

distinctive capability that is central to our reputation and competitive advantage. 
For us, technology is the practical application of scientific knowledge to manage 
risks, capture business value and inform strategy development. This includes 
the research, development, demonstration and acquisition of new technical 
capabilities and support for the deployment of BP’s know-how.

We monitor the potential opportunities and risks presented by emerging 

science, interdisciplinary innovation and new players; natural resource issues and 
climate concerns; and evolving policy concerns, including the current emphasis on 
energy security and efficiency.

 Our technology advisory council, which is comprised of eminent 

technology leaders from business and academia, advises the board and executive 
management on research and technology matters.

Our organization: Business model

Upstream and midstream – playing to our strengths
Our Exploration and Production segment is responsible for our activities in 
oil and natural gas exploration, field development and production; midstream 
transportation, storage and processing; and the marketing and trading of natural 
gas, including liquefied natural gas, together with power and natural gas liquids.

Our exploration division obtains access to and finds resources at scale in the 

world’s key hydrocarbon basins. We are an industry leader in seismic imaging, 
a key technology in the identification of potential hydrocarbon resources. Our 
developments division develops our hydrocarbon resources, applying effective 
project execution and capital efficiency. Our production division then extracts 
resources efficiently and maximizes their recovery.

We focus on areas that play to our strengths – deepwater, gas value chains 

(including the infrastructure required from field to market) and giant fields. We 
are increasing investment with a particular focus on exploration. We actively 
manage our portfolio, including divesting assets when we believe they may be 
more valuable to others than to ourselves. This allows us to focus our leadership, 
technical resources, and organizational capability on the resources we believe are 
most likely to flourish in our portfolio.

In 2011, our upstream and midstream activities took place in 30 countries 
including Angola, Azerbaijan, Canada, Egypt, Norway, Russia, Trinidad & Tobago 
(Trinidad), the UK, the US and other locations within Asia, Australasia, South America, 
North Africa and the Middle East. Exploration and Production also includes gas 
marketing and trading activities, primarily in Canada, Europe and the US. In Russia, 
we have an important associate through our 50% shareholding in TNK-BP, a major oil 
company with exploration assets, refineries and other downstream infrastructure.

Technology will continue to play a critical role in our upstream activities, as the 
upstream technology flagships diagram demonstrates. In addition, our Project 
20KTM is a significant new initiative that illustrates how new advances have the 
potential to deliver material value. Through this, we are investing in technology to 
enable exploration, development and production of reservoirs that were previously 
beyond reach due to high reservoir pressures, including those at a pressure 
between 15,000 and 20,000 pounds per square inch. Successful deployment 
of these technologies would enable us to further develop a number of our 
existing resources substantially, and we also see opportunities to develop new 
onshore and offshore resources – both as BP and in partnership with national oil 
companies.

Downstream – working across our value chains
Our Refining and Marketing segment is responsible for the refining, manufacturing, 
marketing, transportation, and supply and trading of crude oil, petroleum, 
petrochemicals products and related services to wholesale and retail customers.

We have significant operations in Europe, North America and Asia, and we also 
manufacture and market our products across Australasia, southern Africa and Central 
and South America. In total we market our products in more than 70 countries.
The segment comprises three main businesses: fuels, lubricants and 

petrochemicals. All of our businesses operate as value chains. Previously we 
discussed the segment under the headings of fuels value chains and international 
businesses, but we now report the value chains by business.

The fuels businesses sell refined petroleum products including gasoline, 
diesel and aviation fuel. Within this, the fuels value chains (FVCs) integrate the

activities of refining, logistics, marketing, and supply and trading on a regional 
basis. This recognizes the geographic nature of the markets in which we compete, 
providing the opportunity to optimize our activities from crude oil purchases to 
end-consumer sales through our physical assets (refineries, terminals, pipelines 
and retail stations). In addition, we operate a global aviation fuels business and an 
LPG marketing business, from which we intend to divest the bulk and bottled LPG 
marketing operations.

We own or have a share in 16 refineries including five in the US and seven 
in Europe. Our focus is on complex, upgraded refineries that are able to process 
cheaper feedstocks yet yield more valuable products. We also market fuels 
through around 21,800 retail sites, principally in the US, Europe, Australia and 
southern Africa. Many of our retail sites are now operated by franchisees with 
whom we work in close partnership as we seek to ensure our standards and 
brand are consistently applied. We divest assets and businesses when we believe 
they will be of greater value to others. In 2011, we announced that we are seeking 
buyers for our Texas City refinery; and for our Carson refinery near Los Angeles, 
together with its associated integrated marketing business in southern California, 
Arizona and Nevada.

Our lubricants business is involved in manufacturing and marketing lubricants 

and related services to markets around the world. In 2011, approximately 45% of 
our profit from lubricants was generated from non-OECD markets, and we see 
good opportunities for further growth in these areas. We market lubricants to the 
automotive, industrial, marine, aviation and energy markets. The business blends 
and markets lubricants globally through our key brands of Castrol, BP and Aral. 
Our strategic relationships with our original equipment manufacturing partners 
provide the ongoing collaboration needed to develop the next generation of high-
performance lubricants, such as Castrol EDGE.

Our petrochemicals business operates on a global basis and includes the 
manufacture and marketing of petrochemicals that are used in many everyday 
products, such as plastic bottles and textiles for clothing. Future growth in our 
business is focused on the demand centres of Asia, where our relationships 
with joint venture partners are key to our strategy in these increasingly important 
markets. From 2012 we plan to create a new revenue stream in petrochemicals 
through licensing some of our leading technology.

shareholders. As at 31 December 2011, it comprised the chairman, nine non-
executive directors together with the group chief executive; the chief financial 
officer and the chief executive of BP’s Refining and Marketing segment.

The executive directors have responsibility for the day-to-day running of BP, 
while the non-executive directors bring independent viewpoints and a breadth of 
experience, along with insights into how other companies manage key issues. 
Five of our current non-executive directors have been appointed since 2010. 
Board committees play an increasingly important role. The committees 
are: the Gulf of Mexico committee; the safety, ethics and environment assurance 
committee; the audit committee; the remuneration committee; the nomination 
committee; and the chairman’s committee. In addition, an independent international 
advisory board advises our chairman, group chief executive and board on strategic 
and geopolitical issues relating to the long-term development of the group.

In 2011, an internal review of risk management systems and processes 
was undertaken to enhance clarity, simplicity and the consistency of our risk 
management system, from front-line operations through to the boardroom. See 
Our management of risk on page 42 for further information. Also in 2011, a new 
board steering group completed a review of board governance. The review looked 
at the structure, roles, tools and processes involved in board and board committee 
work. The findings of the review will inform a new set of board governance 
principles, which will be published later in 2012. See Board performance report on 
pages 120-133 for further information.

Our employees
We employ approximately 83,400 people (including 14,600 service station staff), 
the majority of whom are located in the US and Europe. The Deepwater Horizon 
oil spill in 2010 had a profound effect on our employees, and to strengthen and 
standardize what we do, we launched a range of internal change projects in 2011. 
See How BP is changing on page 36 for more information. 

In addition, we are working hard to address a critical issue facing everyone 
in our industry – a growing skills gap. This, alongside the increasing demand for 
energy products and complexity of projects, means that attracting and retaining 
skilled and talented people is vital.

Our leadership has focused on ensuring that appropriate development 
opportunities and succession plans are in place to build capability. To supplement 
our existing internal capability, we also target experienced and skilled professionals 
in the external market and are continuing to increase our intake of graduates to 
create a strong internal talent pipeline for the future.

We provide a range of professional development programmes and training 
to build capabilities in our people and are committed to creating an inclusive work 
environment where everyone is treated fairly, with dignity, respect and without 
discrimination.

Our organization: People and governance

Contractors and suppliers 
Like our peers, BP rarely works in isolation. In 2011, for example, 55% of the 
374 million hours worked were carried out by contractors. These individuals play an 
important role for BP. During the year we initiated a far-reaching review of the way 
we work with third parties, particularly those involved in potential high-consequence 
activities. We are now implementing a range of measures based on our findings, 
with a focus on six key themes: consistent standards and priorities; fewer suppliers 
to enable deeper, longer-term relationships; detailed and systematic selection of 
contractors; clear and specific contracts; intensive oversight and verification; and 
assurance that supplier personnel are competent.

Our values
“Our approach is built on respect, being consistent and having the courage to do 
the right thing. We believe success comes from the energy of our people. We 
have a determination to learn and to do things better. We depend upon developing 
and deploying the best technology, and building long-lasting relationships. We are 
committed to making a real difference in providing the energy the world needs 
today, and in the changing world of tomorrow. We are one team – a group of diverse 
individuals from around the world united by shared values and a drive to rebuild BP.”

These words, taken from the BP code of conduct, capture what we strive 

to stand for as a company – our renewed values. They are an expression of work 
done across BP in 2011 to define and renew our principles and values. This work 
was carried out in response to the events of recent years, which have caused us 
to reflect on what is important and how we do what we do.

We launched our renewed values in 2011. They represent the qualities and 
actions we wish to see in BP, and those that BP already demonstrates when it is 
at its best. The values are aligned with our code of conduct and are there to guide 
the way we do business and the decisions we take, every day. Safety has been 
re-emphasized as our number one priority.

The values are much more than words – we are actively seeking to embed these 
values at the heart of the systems and processes we are introducing to unify 
and strengthen our business. We are both enforcing and incentivizing values-led 
behaviour. For example, our updated performance and reward system, which 
came into effect on 1 January 2012, now creates an explicit link between our 
values and the way individuals are judged and rewarded within BP. 

Our values 

Safety 

Respect 

This statement of our values 
expresses our aspirations and 
intentions for BP, as we work 
together to strengthen safety and 
risk management, earn back trust 
and create value. Our values are 
aligned with, and an extension of, 
our code of conduct.

Safety is good business. 
Everything we do relies upon 
the safety of our workforce 
and the communities 
around us. We care about 
the safe management of 
the environment. We are 
committed to safely delivering 
energy to the world.

Excellence 

Courage 

We are in a hazardous 
business, and are committed 
to excellence through the 
systematic and disciplined 
management of our 
operations. We follow and 
uphold the rules and standards 
we set for our company. We 
commit to quality outcomes, 
have a thirst to learn, and to 
improve. If something is not 
right, we correct it.

What we do is rarely easy. 
Achieving the best outcomes 
often requires the courage 
to face difficulty, to speak 
up and stand by what we 
believe.  We always strive to 
do the right thing. We explore 
new ways of thinking and are 
unafraid to ask for help. We 
are honest with ourselves, and 
actively seek feedback from 
others. We aim for an enduring 
legacy, despite the short-term 
priorities of our world.

We respect the world in  
which we operate. It begins 
with compliance with laws and 
regulations. We hold ourselves 
to the highest ethical standards 
and behave in ways that earn 
the trust of others. We depend 
on the relationships we have 
and respect each other and 
those we work with. We 
value diversity of people and 
thought. We care about the 
consequences of our decisions, 
large and small, on those 
around us.

One Team 

Whatever the strength of the 
individual, we will accomplish 
more together. We put the 
team ahead of our personal 
success and commit to 
building its capability. We trust 
each other to deliver on our 
respective obligations. 

Our code
The BP code of conduct sets the standard that we all work to. It is aligned with 
our values, group standards and legal requirements, and it clarifies the ethics and 
compliance expectations for everyone who works at BP. The code was updated 
in 2011 and now puts greater emphasis on a values-based approach. Where 
rules are not stated explicitly, our everyday business decisions will be guided by 
our values.

Business review: Group overviewOur organization: How BP is changing

Following the tragic events in the Gulf of Mexico 
in 2010, we initiated a wide-ranging programme 
designed to enhance safety and risk management 
within the group, earn back trust and restore value. 
Much was achieved in 2011, but there is a great 
deal more to do.

Upstream 
restructuring

Values and 
behaviours

We are strengthening our 
group-wide application 
of enhanced, consistent 
standards driven by our 
safety and operational 
risk function, which is 
independent from the 
business segments.

We are enhancing the clarity, 
consistency and quality of 
the way risks are understood, 
reported and acted upon, 
from front-line operations 
to the boardroom.

We restructured to create 
three global divisions – 
exploration, developments 
and production. These 
constitute the biggest 
changes in BP’s upstream 
business for 20 years.

We have refreshed our 
values and behaviours and 
continue embedding these 
into how we work together.

Our strategy

In 2011, we put forward a clear 10-point plan that 
defines what you can expect from us, and what 
you will be able to measure, through to 2014.

Following the tragic Deepwater Horizon oil spill, we set out a strategy designed to 
deliver stability, and restore trust and value. Our first priority was to work to make 
BP a safer, more risk-aware business. We pursued that strategy with purpose 
through 2011 and have now laid out a 10-point plan for BP’s future.

Our renewed strategy is designed to make BP a simpler, stronger company 

that plays to its strengths. It concentrates our distinctive talents on high value, 
advantaged assets, with new and enhanced structures, process and discipline 
serving to support and sustain our businesses and operations. Our goal is to grow 
operating cash flows to enable us to both invest for future growth and increase 
distributions to shareholders.

Our upstream strategic focus is aligned with what we see as the five key 
drivers of value growth in our operations. These are: managing risk; increasing 
investment, with a particular focus on exploration; managing our portfolio actively; 
growing operating cash faster than production; and focusing on the major growth 
engines that capitalize on our strengths – deepwater, gas value chains and giant 
fields.

In the downstream, we are in the business of hydrocarbon value chains, and 

with an intense focus on safe and reliable operations, we believe we now have 
the platform to sustain and grow a world-class business capable of generating 
leading returns and cash flow growth.

Below BP has a 
significant presence 
in Trinidad & Tobago, 
operating 13 offshore 
platforms and holding an 
interest in Atlantic LNG.

Above Having achieved our 
improved production target 
in 2010, BP and partners are 
working to refurbish the 
wells and facilities at the 
Rumaila field in Iraq.

Business review: Group overviewOur strategy: Strategic priorities

Our 10-point plan 
Our 10-point plan is how we intend to build a stronger, safer BP. The first five points 
are things you can expect from us; the second five are things you can measure.

  What you can expect from us

1   We will keep a relentless focus on safety and managing risk

We are determined that BP will deliver world-class performance in safety, risk 
management and operational discipline. We will be a company that systematically 
applies our global standards as a single team.

2   We will play to our strengths

We have had major successes at finding oil and gas at scale. We are also among 
the real pioneers of deepwater exploration. We have decades of experience 
managing giant fields and developing valuable gas value chains. We have built 
a world-class downstream business. Underpinning these strengths are deep 
capabilities in building relationships and in developing technologies.

Left BP moves gas 
from 6,000 metres 
below the Shah Deniz 
field in Azerbaijan to 
markets in Western 
Europe, 3,000 
kilometres away.

Right As part of a 
$1.2 billion investment 
announced in 2011, 
the Kinnoull reservoir, 
UK North Sea, will be 
connected to BP’s 
Andrew platform.

3   We will be stronger and more focused

We intend to be a stronger and more focused BP, with a base of assets that is 
high graded and high performing.

4   We will be simpler and more standardized

Our organization is already much more standardized than it was before the 
Deepwater Horizon oil spill. The transformation of our Exploration and Production 
segment from a regional business to one that is managed along lines of functional 
expertise is an example of this. Our footprint is smaller, with fewer assets and 
operations in fewer countries. Our internal reward and performance processes are 
more streamlined. This should drive better and more sustainable performance in 
safety, quality and efficiency, with less variation.

5   We will improve transparency through our reporting

We will improve transparency in the reporting of our business segments. We now 
break out the numbers of certain parts of our businesses, such as lubricants and 
petrochemicals in the downstream. From the first quarter of 2012, the group’s 
investment in TNK-BP will be reported as a separate operating segment.

38    BP Annual Report and Form 20-F 2011

 
What you can measure

6   Active portfolio management

We want to focus our portfolio further on our areas of strength, and deliver 
increased financial flexibility. By the end of 2013, we expect to have 
completed $38 billion of disposals since the start of 2010.

7   New projects with higher margins

We have a strong list of upstream projects due to come onstream over the 
next three years. By 2014, unit cash marginsa on production from this new 
wave of projects are expected to be around double our existing average.b

8   Operating cash flow growth

We are aiming to generate an increase of around 50% net cash provided by 
additional operating activities by 2014 compared with 2011c – approximately 
half from ending Deepwater Horizon Oil Spill Trust fund payments and 
around half from operations.

9   Use of cash flow for reinvestment and distributions

We will use additional operating cash prudently. We want to use around half 
for increased investment in our project inventory for growth, and around half 
for other purposes. This may include increased distributions to shareholders 
through dividends or share buybacks or repayment of debt.

10   Strong balance sheet

We intend to enhance the strength of our balance sheet by targeting our 
level of gearingd at the lower half of the 10-20% range over time.

a  Unit cash margin is net cash provided by operating activities for the relevant projects in our Exploration 
and Production segment, divided by the total number of barrels of oil and gas equivalent produced for the 
relevant projects. It excludes dividends and production for TNK-BP.
b  Assuming a constant oil price of $100 per barrel.
c  Assuming an oil price of $100 per barrel in 2014. The projection reflects our expectation that all required 
payments into the $20-billion trust fund will have been completed by the end of 2012. It does not reflect 
any cash flows relating to other liabilities, contingent liabilities, settlements or contingent assets arising 
from the Gulf of Mexico oil spill which may or may not arise at that time. We are not able to reliably 
estimate the amount or timing of a number of contingent liabilities. See Financial statements – Note 43 on 
page 249 for further information.
d  Gearing refers to the ratio of the group’s net debt to net debt plus equity and is a non-GAAP measure. See 
Financial statements – Note 35 on page 230 for further information including a reconciliation to gross debt, 
which is the nearest equivalent measure on an IFRS basis.

Our management of risk

Putting safety and risk management at the heart 
of the company is the foundation for building trust 
and creating value. In 2011 we began a process 
to review, refresh and enhance our management 
of risk.

The role of the board
The board is responsible for the direction and oversight of BP as set out in its 
governance principles, which include that it will satisfy itself that the material 
risks to BP are identified and understood and that systems of risk management, 
compliance and control are in place to mitigate such risks. The board, through 
its governance principles, requires the group chief executive to operate with a 
comprehensive system of controls and internal audit to identify and manage the 
risks that are material to BP. See Risk management: from operations to the board 
on page 122. 

Our system of internal control
The system of internal control comprises the holistic set of management systems, 
organizational structures, processes, standards and behaviours that are employed 
to conduct the business of BP. The system is designed to meet the expectations 
of internal control of the Corporate Governance Code in the UK and of COSO 
(Committee of Sponsoring Organizations of the Treadway Commission) in the US. 

Key elements of the system include: the control environment; the 

management of risk and operational performance; and the management of people 
and individual performance. As such, BP’s risk management system is an integral 
part of our system of internal control, and is designed to be a simple, consistent 
and clear framework for managing and reporting all risk from the group’s 
operations to the board.

Review of risk management
In 2011, we initiated a review of our risk management system. The review 
considered the group’s existing risk management system, along with good 
practices in risk management from outside the company, with a view to 
identifying what might be done to enhance the clarity, simplicity and consistency 
of our risk management system.

Using the findings of this review, we have begun implementing 

enhancements to the way we manage and report risks. This has involved the 
development of common language, concepts and templates for consistent 
reporting on risks and risk management; designing enhancements to board and 
executive processes; and greater alignment of risk management activities and 
business processes. These improvements build from our existing management 
systems, standards and practices and we will continue to embed these in 2012. 
See the information on Safety and operational risk on page 65 for examples of 
enhancements to the S&OR function and management of safety and operational 
risks.

42    BP Annual Report and Form 20-F 2011

Our risk management system
Our enhanced risk management system focuses on three levels of activity:
 •	 First,	the	system	helps	facilitate	day-to-day	risk	management	in	the	group’s	

operations and functions, with the approach varying according to the types of 
risk we face. Risks are to be identified and managed, and actions to improve the 
management of risk are to be put in place where necessary. Our aim is to address 
each different type of risk as well as we can – promoting safe, compliant and 
reliable operations.

 •	 Second,	for	our	businesses	and	functions,	risks	arising	are	to	be	collated	

periodically, risk management activities are to be assessed, and any necessary 
further improvements or actions are to be planned. The system is designed 
to facilitate this by incorporating a standardized form that we call the risk 
management report (RMR) for businesses and functions to report consistently  
the risks they face for management consideration, challenge, resource allocation 
and intervention.

Left Operations at BP’s 
Shah Deniz platform, 
Azerbaijan. Located 
offshore, 40 miles 
south east of Baku, 
Shah Deniz is thought 
to hold 1 trillion cubic 
metres of gas.

Right BP’s state-of-the-
art Houston monitoring 
centre provides real-
time communications 
between rigs in the 
Gulf of Mexico and 
experts based onshore.

 •	 Third,	the	system	facilitates	executive	and	board	oversight	and	governance	over	
the management of significant risks. It requires executive team level involvement 
in the finalization of risk management activities and improvement plans for 
the group’s most significant individual risks. Using the consistent bottom-up 
risk identification and assessment process, coupled with top-down executive 
overview, the system requires that the most significant risks requiring oversight 
are identified. Oversight of the management of these risks is to be provided 
through regular review by the board or one of its committees.

Drawing on this input, our enhanced risk management system assists us in our:

 •	 Understanding	of	the	risk	environment	for	input	into	our	strategy.
 •	 Understanding	of	which	risk	types	we	operate	with,	given	our	strategy.
 •	 Identification	and	assessment	of	actual	specific	risks	and	the	potential	exposure	

they may represent.

 •	 Decision-making	on	how	best	to	deal	with	those	risks	to	manage	our	overall	

potential exposure.

 •	 Active	management	of	identified	risks.
 •	 Reporting	to	management	and	the	board	about	how	those	risks	are	managed,	

and monitoring of our potential exposure.

 •	 Obtaining	of	assurance	over	the	effectiveness	of	the	management	of	those	risks.
 •	 Interventions	for	improvements	in	the	management	of	those	risks	where	

necessary.

 •	 Consideration	of	the	effect	of	the	external	environment	and	our	business	

activities on the principal activities of our risk management system.

BP Annual Report and Form 20-F 2011    43

Business review: Group overviewOur management of risk

During 2011, functions, strategic performance units, divisions and segments 
within BP were requested to prepare RMRs using the new, common approach. 
This helped provide an overall data set of the key risks identified, an assessment 
of their potential impact and likelihood on a consistent basis, information on how 
they are being managed and any actions planned or in progress to improve the 
management of risk. Based on these RMRs, together with additional executive 
overview, a single group RMR has been prepared. Those risks identified on the 
group RMR as requiring particular group-level oversight in the coming year have 
been allocated to specific board and executive committees for oversight and 
monitoring. These are discussed below. Also see Risk factors on pages 59-63  
for a description of the material risks we face in our business.

Risk management can also be a foundation for creating value. The 
willingness to take and appropriately manage certain risk is fundamental to the 
success of any commercial enterprise. For example, in our upstream business 
we consciously place significant amounts of capital at risk in exploring for new 
hydrocarbon resources. Where this exploration is successful, we would generally 
expect it to lead to future increases in our proved reserves and future cash flows. 
However, exploration expenditure may not yield adequate returns, for example in 
the case of unproductive wells or discoveries that prove uneconomic to develop.

Safety and operational risk function
We have redefined and strengthened the scope and accountabilities of the 
group function for safety and operational risk (S&OR), creating a new team 
independent of business line management to drive safe, compliant and reliable 
operations in BP. The S&OR function, which continues to build towards its 
full staffing complement, includes S&OR teams which have been formed to 
work alongside line management but are independent of them. In pursuit of 
safe, compliant and reliable operations, S&OR personnel can assist, challenge 
and escalate or intervene as necessary to promote and assure the operating 
businesses’ systematic and disciplined application of global standards on safety 
and operational risk. The function helps provide assurance as to whether line 
operations are carried out in accordance with the group’s operating management 
system, and seeks to facilitate more comprehensive and assured S&OR risk 
action plans for operational units, more incisive interventions on emerging risk 
situations, and improved investigations and learning from significant incidents.

How we seek to manage our risks
The following is a summary of how we seek to manage the risks we have 
identified as having a high priority in 2012. There can be no guarantee that our 
risk management activities will mitigate or prevent these, or other, risks from 
occurring.

Strategic risks
In response to risks associated with the general macroeconomic outlook and 
changes in prices and markets, we monitor early warnings from our treasury 
team and customer-facing businesses. To manage our liquidity, financial capacity 
and financial exposure risks, we apply our financial framework (see Liquidity 
and capital resources on page 103) and we conduct liquidity stress testing and 
scenario-planning interventions.

Corporation, Air BP has

more reliable way to test 
aviation lubricants.

Our current strategic priorities are set out in our 10-point plan (see pages 

38-39). Among other things, this aims to target investments and disposals 
efficiently, renew and reposition our portfolio and deliver our major projects to 
plan. As part of managing the risks to delivery of the 10-point plan we conduct 
regular planning and performance-monitoring activity, including the planning 
of disposals; we focus on the delivery of major projects; and we pursue the 
development of continued technological advances and innovation.

The diverse locations of our operations around the world exposes us to a 
wide range of political developments and consequent changes to the economic 
and operating environment. For example, our investments in Russia could be 
adversely affected by heightened political and other environment risks. As such, 
we try to actively manage our relationships in Russia, including with the Russian 
federal government and with TNK-BP. We also seek to manage the group’s 
exposure in Russia through our development of BP’s overall portfolio.

Many of our major projects and operations are conducted through joint 
ventures or associates and through contracting and sub-contracting arrangements 
where BP may not have full operational control. We seek to manage such joint 
venture and contractor relationships actively, and this may include monitoring 
compliance with applicable standards.

As a result of the Deepwater Horizon oil spill there is significant uncertainty 

regarding the extent and timing of costs and liabilities relating to the incident, 
the impact of the incident on our reputation and the resulting possible impact on 
our licence to operate including, among other things, our ability to access new 
opportunities. In addressing these risks we seek to co-operate with investigators 
and we encourage the application of responsible and objective scientific analysis 
in determining outcomes. We always seek to comply with local regulations and, 
in some cases, our required practices will exceed regulations if our assessment 
of the operating risk indicates it would be beneficial to do so. We seek to engage 
with local communities in order to foster improved relationships and reputation.

Business review: Group overviewOur management of risk

Safety and operational risk
The nature of the group’s operations exposes us to a wide range of significant 
health, safety and environmental risks such as incidents associated with the 
drilling of wells, operation of facilities, transportation of hydrocarbons and product 
quality. In addressing these risks we seek to apply our operating management 
system (OMS) including group and engineering technical practices as applicable. 
We seek to conduct maintenance and equipment testing and to apply product 
quality control and testing procedures. We also provide our staff with training and 
competency development. To better manage the risks inherent in drilling wells 
where we are the operator, we conduct activity through a global wells organization 
that is accountable for systems and processes for designing, constructing and 
managing wells. See Safety on page 66 for information on the recommendations 
of BP’s internal investigation into the Deepwater Horizon oil spill and the actions 
we are pursuing to address them.

Security threats require continuous oversight and control as hostile 
actions against our staff, our activities and our digital infrastructure (cyber 
security) could cause harm to people and could disrupt our operations. We have 
procedures that are intended to monitor for threats and vulnerabilities. We also 
maintain business continuity plans.

Crisis-management plans are developed to help us to respond effectively 
to emergencies and to avoid a potentially severe disruption in our business and 
operations. For deepwater drilling, interim requirements for oil spill preparedness 
and response, including crisis management response capability, were introduced 
in 2011 in the Gulf of Mexico. The intention is to build on these interim 
requirements to put in place group-wide practices for both oil spill preparedness 
and response and crisis management.

Successful recruitment and development of staff is central to our plans. 

We have programmes to recruit both graduates and experienced staff and 
we maintain succession plans for key roles. We also operate training and 
development programmes, including relating to leadership, and we engage all 
employees in regular performance-management processes.

Compliance and control risk
Ethical misconduct or breaches of applicable laws or regulations could be 
damaging to our reputation, results of operations and shareholder value and 
could affect our licence to operate. Central to managing these risks is our code 
of conduct (see page 31), the requirements of which apply to all employees, 
supported by our various group standards covering issues such as anti-bribery and 
corruption, anti-money laundering and competition/anti-trust law compliance. We 
seek to monitor for new regulations and legislation and plan our response to them. 
We also operate a range of compliance training and monitoring programmes for 
our employees.

In the normal course of business, we are subject to risks around our 
treasury and trading activities, which could arise from shortcomings or failures 
in our systems, risk management methodology, internal control processes 
or employees. In addressing these risks, we have adopted specific operating 
standards and control processes, including guidelines in relation to trading, and 
seek to monitor compliance through dedicated compliance and risk organizations. 
We also seek to maintain a positive and collaborative relationship with regulators 
and the industry at large.

Our performance

2011 was a year of further stern tests for BP. Our 
challenge was to stabilize the company and meet 
our commitments in the Gulf of Mexico while 
laying firm foundations for the future.

We went into 2011 with a clear set of strategic priorities and determination to 
rebuild the company. Our employees have worked to make BP a safer business 
and to earn back trust. We also pushed forward on the journey to grow value over 
the short, medium and long term. The key measures in this section show our 
progress in numbers, and here you can also read about some of the significant 
actions and events that defined our year.

Safety
Our safety and operational risk function (S&OR) is driving the systematic and 
disciplined application of global standards in safety and operational risk across the 
company. We recruited 87 new employees into S&OR during the year, taking its 
total headcount to around 600 against a target headcount of 800.

During the year, as part of our enhanced focus on safety and operational risk 

management, we completed a programme of 47 major upstream turnarounds.
We set enhanced voluntary standards for how we drill in the Gulf of 
Mexico, and implemented new global standards in our operations worldwide. 
For example, in deepwater drilling, where we use drill rigs that are maintained in 
position by computer-controlled systems rather than fixed moorings, we require 
BP-contracted drill rigs to have no fewer than two blind shear rams and a casing 
shear rama in order to provide additional assurance. 

We initiated a review of the way we work with contractors and other 
industry partners. Guided by our findings, we have implemented a range of new 
measures, starting with our offshore rigs. We also reviewed and updated our 
system of risk management – see Our management of risk on pages 42-46. 
And we reviewed and updated our values and behaviours, linked them explicitly 
to an enhanced code of conduct and embedded them in our approach to safety, 
performance management and reward.

a  Shear rams are devices within a blowout preventer designed to cut the drill pipe and seal the well in the 
event of a blowout or other operational emergency.

Business review: Group overviewOur performance

Our upstream business is now reorganized into three divisions – exploration, 
developments and production. We have also reorganized our drilling operations 
into a single global wells organization (GWO), which forms part of the 
developments division and takes a consistent, global approach to managing risk. 
GWO has implemented a number of standard processes since its formation, 
covering activities such as rig start-up and well cementing.

Trust
Released in January 2011, the report of the National Commission on the BP 
Deepwater Horizon Oil Spill and Offshore Drilling identified certain failures of 
management and decision-making within BP and its contractors, as well as 
regulatory failures, to be contributing factors to the accident. See Safety on 
page 65 and Legal proceedings on pages 160-166 for information on other 
investigations and reports. We are committed to working with government 
officials and other operators and contractors to identify and implement operational 
and regulatory changes that will enhance safety practices throughout the oil and 
gas industry. BP teams have travelled to 25 countries to share the lessons learned 
from events in the Gulf of Mexico with our industry, regulators and governments. 
We also shared equipment and technology developed during the response with 
the Marine Well Containment Company in the US.

On the ground, the focus of our work in the Gulf of Mexico shifted from 

response to recovery. The majority of the clean-up work required along the 
shoreline has now been completed. We are encouraged by local and state reports 
that indicate tourism in many areas of the region is rebounding. And all federal 
commercial fishing areas had been reopened by April 2011. We are still at work on 
the recovery and remain committed to meeting our responsibilities in the region.
By the end of 2011, we had paid $15.1 billion into the $20-billion Deepwater 
Horizon Oil Spill Trust fund (Trust) set up to meet the costs of the spill. In total, the 
Trust and BP had paid a total of $7.8 billion in claims, advances and other payments 
by the end of 2011.

Value
Our profit in 2011 was $25.7 billion compared with a loss of $3.7 billion in 2010. 
After adjusting for inventory holding gains, our replacement cost profita in 2011 
was $23.9 billion compared with a loss of $4.9 billion in 2010. Cash and cash 
equivalents at the end of 2011 totalled $14.1 billion and our net debt ratiob was 
20.5%. See Financial review on pages 56-58 for further information on the group’s 
financial results.

During 2010 and 2011 combined, we strengthened the group’s financial 

position by completing asset sales totalling almost $20 billion and we have 
announced our intention to make further disposals that would bring the total to 
$38 billion by the end of 2013. Previously this disposal target had been set at 
$45 billion, however it was reduced in November 2011 when we received notice 
of termination from Bridas Corporation of the agreement for their purchase of 
BP’s 60% interest in Pan American Energy LLC. We intend to reduce our net 
debt ratio to the lower half of the 10-20% range over time. During 2011 we 
reached settlements with MOEX USA Corporation (MOEX), Weatherford U.S., 
L.P. (Weatherford), Anadarko Petroleum Corporation (Anadarko) and Cameron 
International Corporation (Cameron) totalling $5.5 billion related to the Deepwater 
Horizon oil spill. All cash received has been paid to the Trust.

a  Replacement cost profit or loss for the group is not a recognized GAAP measure. The equivalent measure 
on an IFRS basis is ‘Profit (loss) for the year attributable to BP shareholders’. See footnote b on page 56 and 
page 110 for further information.
b  Net debt ratio is a non-GAAP measure. See Note 35 on page 230 for the equivalent measure on an 
IFRS basis.

On 3 March 2012, we announced we had reached a settlement with the 
Plaintiffs’ Steering Committee (PSC), subject to final written agreement and 
court approvals, to resolve the substantial majority of legitimate economic loss 
and medical claims stemming from the Deepwater Horizon accident and oil spill. 
The PSC acts on behalf of individual and business plaintiffs in the Multi-District 
Litigation proceedings pending in New Orleans (MDL 2179). We estimate that 
the cost of the proposed settlement would be approximately $7.8 billion, but with 
no net impact on either the income or cash flow statements, since the proposed 
settlement is expected to be payable from the $20-billion Trust. While this is 
BP’s reliable best estimate of the cost of the proposed settlement, it is possible 
that the actual cost could be higher or lower than this estimate depending on the 
outcomes of the court-supervised claims processes. See Legal proceedings on 
page 162 for further information.

Exploration and Production
The replacement cost profit before interest and tax for 2011 was $30,500 million, 
compared with $30,886 million for the previous year. See Exploration and 
Production on page 80 for further information on the segment’s financial results.

Our production was lower than in 2010 due to divestments, the suspension 

of drilling in the Gulf of Mexico and the high number of turnarounds and 
maintenance projects undertaken during the year. However, production began to 
increase from the fourth quarter with the completion of turnarounds in the North 
Sea, Angola and the Gulf of Mexico. Also, two new major projects were brought 
onstream during the year – the BP-operated Serrette field in Trinidad and the 
Pazflor field in Angola, operated by Total.

We had our best year for a decade in terms of access to new upstream 
opportunities, with awards for a total of 55 new exploration licences. We also 
gained approval for our exploration plan for the Kaskida field in the Gulf of Mexico 
– our first drilling permit for an exploration well in the US since the Deepwater 
Horizon oil spill.

In India, we completed a transaction that brings us into a unique relationship 

with Reliance Industries and access to 21 oil and gas blocks which covered 
approximately 83,000 square miles (216,000 square kilometres). In November 
2011 we formed a 50:50 gas marketing joint venture to source and market gas.
In Russia, our plans to form a strategic alliance with Rosneft did not reach 

fruition. Nonetheless, we remain committed to Russia and the ongoing success  
of TNK-BP, which comprises 27% of our reserves and 29% of our production.

In Brazil, we acquired assets from Devon Energy, giving us a material 
position in one of the great deepwater provinces of the world. We started 
upstream operations during the year.

Our performance

In the UK North Sea, we announced plans for investments totalling approximately 
$14 billion – with our partners – in major new project developments.

In Iraq, working with our partners in the Rumaila Operating Organization, 
we met a major milestone in reaching initial production targets agreed for the 
Rumaila field.

Refining and Marketing
Replacement cost profit before interest and tax for 2011 was $5,474 million 
compared with $5,555 million in 2010. Strong refinery operations enabled us to 
capture the benefits of BP’s location advantage in accessing WTI-based crude 
grades and, compared with 2010, the result also benefited from a higher refining 
margin environment and a stronger supply and trading contribution. These 
benefits were partly offset by a significantly higher level of turnarounds in 2011 
than 2010 and negative impacts from the increased relative sweet crude prices in 
Europe and Australia, primarily caused by the loss of Libyan production, and the 
weather-related power outages in the second quarter. See Refining and Marketing 
on page 94 for further information on the segment’s financial results.

Operating performance was strong, with Solomon refining availability of 

94.8% and utilization rates above the industry average. We made significant 
progress on the modernization of our Whiting refinery in the US, which is expected 
to come onstream in the second half of 2013. This project will significantly increase 
the capability of the refinery to process heavy crude and provide it with access to 
crude from the Gulf of Mexico, the mid-continent US and Canada.

We achieved strong performance in our lubricants business, despite 

a difficult marketing environment and increasing base oil prices. In our 
petrochemicals business we received local government approval for our proposed 
1.25 million tonnes per annum purified terephthalic acid (PTA) plant in Zhuhai, 
China, and are now seeking final central governmental approval.

50    BP Annual Report and Form 20-F 2011

We continued to sell non-core assets, and we are progressing with our intention 
to divest about half of our US refining capacity. We completed the divestment of 
non-strategic terminals and pipelines in the US East of Rockies and West Coast, 
and of our fuels marketing businesses in several African countries.

In addition, in February 2012 we announced our intent to sell our bulk and 

bottled LPG marketing businesses in nine countries.

Looking ahead
We believe our actions and achievements in 2011 brought BP to a turning point. 
As we move into 2012, our operations are regaining momentum and we have a 
clear strategy for value creation. Maintaining our absolute commitment to safety, 
our intention is to build on our strengths so we can grow operating cash flows, 
invest for future growth and increase returns to shareholders.

Replacement cost profit (loss) reflects 
the replacement cost of supplies. It is 
arrived at by excluding from profit 
inventory holding gains and losses and 
their associated tax effect. Replacement 
cost profit for the group is the profitability 
measure used by management. It is a 
non-GAAP measure. See page 56 for 
the equivalent measure on an IFRS basis.
In 2011, we returned to profitability 

following the financial impact of the 
Deepwater Horizon oil spill in 2010.

Operating cash flow is net cash flow 
provided by operating activities, from 
the group cash flow statement. 
Operating activities are the principal 
revenue-generating activities of the 
group and other activities that are not 
investing or financing activities.
In 2011, operating cash flow 

recovered, primarily due to a reduction 
in cash outflow in respect of the 
Deepwater Horizon oil spill.

Gearing enables investors to see how 
significant net debt is relative to equity 
from shareholders. Net debt is equal to 
gross finance debt, plus associated 
derivatives, less cash and cash 
equivalents. Net debt and net debt ratio 
are non-GAAP measures. See Financial 
statements – Note 35 on page 230 for the 
nearest equivalent measure on an IFRS 
basis and for further information.

In 2011, gearing decreased slightly 
and we expect it to reduce to the lower 
half of the 10-20% range over time.

Total shareholder return represents the 
change in value of a BP shareholding 
over a calendar year, assuming that 
dividends are re-invested to purchase 
additional shares at the closing price 
applicable on the ex-dividend date.

In 2011, shareholder return improved 

with the resumption of dividends.

We report crude oil, natural gas liquids 
(NGLs) and natural gas produced from 
subsidiaries and equity-accounted 
entities. These are converted to barrels 
of oil equivalent (boe) at 1 barrel of  
NGL = 1boe and 5,800 standard cubic 
feet of natural gas = 1boe.
  Reported production in 2011 was 
10% lower than in 2010, due to higher 
turnaround and maintenance activity, 
and the impact of the drilling 
moratorium in the Gulf of Mexico.

Refining availability represents Solomon 
Associates’ operational availability, 
which is defined as the percentage 
of the year that a unit is available for 
processing after subtracting the 
annualized time lost due to turnaround 
activity and all planned mechanical, 
process and regulatory maintenance 
downtime.
  Refining availability decreased slightly 
in 2011 principally due to the second 
quarter weather-related power outage 
at Texas City.

Proved reserves replacement ratio (also 
known as the production replacement 
ratio) is the extent to which production 
is replaced by proved reserves additions. 
The ratio is expressed in oil equivalent 
terms and includes changes resulting 
from revisions to previous estimates, 
improved recovery and extensions, 
and discoveries. The measure reflects 
both subsidiaries and equity-accounted 
entities, but excludes acquisitions 
and disposals.
  The 2011 reserves additions for 
TNK-BP include the effect of moving 
from life-of-licence measurement to 
life-of-field measurement, reflecting 
TNK-BP’s track record of successful 
licence renewal. Excluding this effect, 
BP’s 2011 reserves replacement ratio 
would have been 83%.

Reported recordable injury frequency 
(RIF) measures the number of reported 
work-related incidents that result in a 
fatality or injury (apart from minor first 
aid cases) per 200,000 hours worked.
In 2011, our workforce RIF, which 
includes employees and contractors 
combined, was 0.36, compared with 
0.61 in 2010 and 0.34 in 2009. The 2010 
group RIF was affected by the Gulf 
Coast response effort.

a  This represents reported incidents 

occurring within BP’s operational HSSE 
reporting boundary. That boundary 
includes BP’s own operated facilities and 
certain other locations or situations.

Loss of primary containment  
is the number of unplanned or 
uncontrolled releases of material, 
excluding non-hazardous releases, such 
as water from a tank, vessel, pipe, railcar 
or other equipment used for 
containment or transfer. 

In 2011, there were 361 losses of 

primary containment compared to 418 in 
2010. Tracking losses of integrity is a 
way of measuring safety performance 
and helping drive improvements.

We report the number of spills of 
hydrocarbons greater than or equal to 
one barrel (159 litres, 42 US gallons). 
We include spills that were contained, 
as well as those that reached land or 
water.

In 2011, there were 228 oil spills of 

one barrel or more. We are taking 
measures to strengthen mandatory 
safety-related standards and processes, 
including operational risk and integrity 
management.

We report greenhouse gas (GHG) 
emissions on a CO2-equivalent basis, 
including CO2 and methane. This 
represents all consolidated entities and 
BP’s share of equity-accounted entities, 
except TNK-BP. In 2010 we did not 
report on GHG emissions associated 
with the Deepwater Horizon incident or 
response (see page 70).
  The decrease of 3.1Mte in 2011 is 
primarily explained by temporary 
reduction in activity in some of our 
businesses as a result of maintenance work 
and also by the sale of assets as part of our 
disposal programme.

The employee satisfaction index comprises 
10 questions that provide insight into levels 
of employee satisfaction across topics such 
as pay and trust in management.
  Our 2010 survey was delayed to allow 
for organizational changes to be reflected 
in the survey construction. This was 
completed and the 2011 survey showed 
improvements in the level of employee 
recognition, with the opportunity for clarity 
about the organization’s priorities 
highlighted as an area for improvement.

b  Relates to BP employees.

Each year we record the percentage of 
women and individuals from countries 
other than the UK and US among BP’s 
group leaders. The number of group 
leaders in 2011 was 516, compared with 
482 in 2010 and 492 in 2009. 
  BP has increased the percentage of 
female leaders in 2011 and remains 
focused on building a more sustainable 
pipeline of diverse talent for the future.

 a This information, insofar as it relates to 2011, has been extracted or derived from the audited consolidated financial statements of the BP group presented on pages 173-258. Note 1 to the financial 
statements includes details on the basis of preparation of these financial statements. The selected information should be read in conjunction with the audited financial statements and related notes 
elsewhere herein.
 b Replacement cost profit or loss reflects the replacement cost of supplies. The replacement cost profit or loss for the year is arrived at by excluding from profit inventory holding gains and losses and 
their associated tax effect. Replacement cost profit or loss for the group is not a recognized GAAP measure. The equivalent measure on an IFRS basis is ‘Profit (loss) for the year attributable to BP 
shareholders’. Further information on inventory holding gains and losses is provided on page 110.
 c Under IFRS these costs are presented as a reconciling item between the sum of the results of the reportable segments and the group results.
 d All capital expenditure and acquisitions during the past five years have been financed from cash flow from operations, disposal proceeds and external financing. 2008 included capital expenditure of 
$2,822 million and an asset exchange of $1,909 million, both in respect of our transaction with Husky Energy Inc., as well as capital expenditure of $3,667 million in respect of our purchase of all of 
Chesapeake Energy Corporation’s interest in the Arkoma Basin Woodford shale assets and the purchase of a 25% interest in Chesapeake’s Fayetteville shale assets. 2007 included $1,132 million for the 
acquisition of Chevron’s Netherlands manufacturing company.
 e 2011 included $1,096 million associated with deepening our natural gas asset base. 2010 included capital expenditure of $900 million relating to the formation of a partnership with Value Creation Inc.
 f The number of ordinary shares shown has been used to calculate per share amounts.
 g Net debt and the ratio of net debt to net debt plus equity are non-GAAP measures. We believe that these measures provide useful information to investors. Further information on net debt is given in 
Financial statements – Note 35 on page 230.

Profit or loss for the year
Profit attributable to BP shareholders for the year ended 31 December 
2011 was $25,700 million and included inventory holding gainsa, net of 
tax, of $1,800 million and a net credit for non-operating items, after tax, of 
$2,195 million. In addition, fair value accounting effects had a favourable 
impact, net of tax, of $47 million relative to management’s measure of 
performance. Non-operating items in 2011 included a $3.7 billion pre-tax 
credit relating to the Gulf of Mexico oil spill. More information on non-
operating items and fair value accounting effects can be found on page 58. 
See Gulf of Mexico oil spill on page 76 and in Financial statements – Note 2 
on page 190 for further information on the impact of the Gulf of Mexico oil 
spill on BP’s financial results.

Loss attributable to BP shareholders for the year ended 31 December 2010 
included inventory holding gains, net of tax, of $1,195 million and a net charge 
for non-operating items, after tax, of $25,449 million. In addition, fair value 
accounting effects had a favourable impact, net of tax, of $13 million relative 
to management’s measure of performance. Non-operating items in 2010 
included a $40.9 billion pre-tax charge relating to the Gulf of Mexico oil spill.
Profit attributable to BP shareholders for the year ended 

31 December 2009 included inventory holding gains, net of tax, of 
$2,623 million and a net charge for non-operating items, after tax, of 
$1,067 million. In addition, fair value accounting effects had a favourable 
impact, net of tax, of $445 million relative to management’s measure of 
performance.

56    BP Annual Report and Form 20-F 2011

Business review 
 
 
 
 
The primary additional factors affecting the financial results for 2011, 
compared with 2010, were higher realizations, higher earnings from equity-
accounted entities, a higher refining margin environment and a stronger 
supply and trading contribution, partly offset by lower production volumes, 
rig standby costs in the Gulf of Mexico, higher costs related to turnarounds, 
higher exploration write-offs, and negative impacts of increased relative 
sweet crude prices in Europe and Australia, primarily caused by the loss of 
Libya production and the weather-related power outages in the US.

The primary additional factors affecting the financial results for 

2010, compared with 2009, were higher realizations, lower depreciation, 
higher earnings from equity-accounted entities, improved operational 
performance, further cost efficiencies and a more favourable refining 
environment in Refining and Marketing, partly offset by lower production, 
a significantly lower contribution from supply and trading (including gas 
marketing) and higher production taxes.

See Exploration and Production on page 80, Refining and Marketing 

on page 94 and Other businesses and corporate on page 101 for further 
information on segment results.

 a Inventory holding gains and losses represent the difference between the cost of sales calculated 
using the average cost to BP of supplies acquired during the year and the cost of sales calculated 
on the first-in first-out (FIFO) method, after adjusting for any changes in provisions where the net 
realizable value of the inventory is lower than its cost. BP’s management believes it is helpful to 
disclose this information. An analysis of inventory holding gains and losses by business is shown in 
Financial statements – Note 6 on page 200 and further information on inventory holding gains and 
losses is provided on page 110.

Finance costs and net finance expense relating to pensions and other 
post-retirement benefits
Finance costs comprise interest payable less amounts capitalized, and 
interest accretion on provisions and long-term other payables. Finance 
costs in 2011 were $1,246 million compared with $1,170 million in 2010 
and $1,110 million in 2009.

Net finance income relating to pensions and other post-retirement 

benefits in 2011 was $263 million compared with net finance income 
of $47 million in 2010 and net finance expense of $192 million in 2009. 
In 2011, compared with 2010, the improvement largely reflected the 
additional expected returns on assets following the increases in the 
pension asset base at the end of 2010 compared with the end of 2009.
During 2011 the value of our pension assets declined and this, 

combined with changes to assumptions used to value benefit obligations, 
most notably lower discount rates, meant that the deficit relating to 
pension and other post-retirement benefits increased to $12.0 billion at the 
end of the year (2010 $7.7 billion).

Taxation
The charge for corporate taxes in 2011 was $12,737 million, compared 
with a credit of $1,501 million in 2010 and a charge of $8,365 million in 
2009. The effective tax rate was 33% in 2011, 31% in 2010 and 33% in 
2009. The group earns income in many countries and, on average, pays 
taxes at rates higher than the UK statutory rate of 26%. The increase in the 
effective tax rate in 2011 compared with 2010 primarily reflects a higher 
level of income earned in jurisdictions with a higher tax rate. The decrease 
in the effective tax rate in 2010 compared with 2009 primarily reflected the 
absence of a one-off disbenefit that featured in 2009 in respect of goodwill 
impairment, and other factors.

Acquisitions and disposals
In 2011, BP acquired from Reliance Industries Limited (Reliance) a 30% 
interest in each of 21 oil and gas production-sharing agreements operated 
by Reliance in India for $7.0 billion. We completed the purchase, for 
$3.6 billion, of 10 exploration and production blocks in Brazil, which was 
the final part of a $7-billion transaction with Devon Energy that had been 
announced in March 2010, and our Alternative Energy business acquired 
the Brazilian sugar and ethanol producer Companhia Nacional de Açúcar e 
Álcool (CNAA) for $0.7 billion. See Financial statements – Note 3 on page 
194 for further details of the business combinations undertaken during  
the year.

Total disposal proceeds received during 2011, including the repayment 
of the disposal deposit relating to Pan American Energy LLC (PAE) (see 
below), were $2.7 billion.

In Exploration and Production, disposal proceeds included 

$0.6 billion from the sale of our upstream assets in Pakistan to United 
Energy Pakistan Limited, a subsidiary of United Energy Group (UEG), 
$0.5 billion from the sale of half of the 3.29% interest in the Azeri-Chirag-
Gunashli (ACG) development in the Caspian Sea which we had acquired 
from Devon Energy in 2010 to Azerbaijan (ACG) Limited and $0.5 billion 
from the sale of our interests in the Wytch Farm, Wareham, Beacon and 
Kimmeridge fields to Perenco UK Ltd. In addition, further payments of 
$1.1 billion were received on completion of the sales of our upstream and 
certain midstream interests in Venezuela and Vietnam and our oil and gas 
exploration, production and transportation business in Colombia, for which 
we had received $2.3 billion in 2010 as deposits. In November 2011, BP 
received from Bridas Corporation (Bridas) a notice of termination of the 
agreement for their purchase of BP’s 60% interest in PAE. As a result, the 
deposit of $3.5 billion relating to the sale of PAE which had been received 
by BP in 2010 was repaid to Bridas.

In Refining and Marketing we made disposals totalling $0.7 billion, 

which included completion of the divestment of non-strategic pipelines and 
terminals in the US, announced in 2009, for $0.3 billion and the disposal of 
our fuels marketing businesses in several African countries (see Refining 
and Marketing on page 97 for more details) for $0.2 billion.

Within Other businesses and corporate, we completed the sale of 

BP’s wholly-owned subsidiary, ARCO Aluminum Inc., to a consortium of 
Japanese companies for $0.7 billion.

In 2010, BP acquired a major portfolio of deepwater exploration 

acreage and prospects in the US Gulf of Mexico and an additional interest 
in the BP-operated ACG developments in the Caspian Sea, Azerbaijan for 
$2.9 billion, as part of a $7-billion transaction with Devon Energy. Total 
disposal proceeds during 2010 were $17 billion, which included $7 billion 
from the sale of US Permian Basin, Western Canadian gas assets, and 
Western Desert exploration concessions in Egypt to Apache Corporation 
(and an existing partner that exercised pre-emption rights), and $6.2 billion 
of deposits received in advance of disposal transactions expected to 
complete in 2011. Of these deposits received, $3.5 billion was for the sale 
of our interest in PAE to Bridas, however, this was subsequently repaid to 
Bridas at the end of 2011 following the termination of the sale agreement. 
See above and Financial statements – Note 4 on page 196 for further 
information. The deposits received also included $1 billion for the sale of 
our upstream and midstream interests in Venezuela and Vietnam to TNK-
BP, and $1.3 billion for the sale of our oil and gas exploration, production 
and transportation business in Colombia to a consortium of Ecopetrol and 
Talisman.

In Refining and Marketing we made disposals totalling $1.8 billion in 

2010, which included our French retail fuels and convenience business to 
Delek Europe, the fuels marketing business in Botswana to Puma Energy, 
certain non-strategic pipelines and terminals in the US, our interests in 
ethylene and polyethylene production in Malaysia to Petronas and our 
interest in a futures exchange.

There were no significant acquisitions in 2009. Disposal proceeds in 
2009 were $2.7 billion, principally from the sale of our interests in BP West 
Java Limited, Kazakhstan Pipeline Ventures LLC and LukArco, and the sale 
of our ground fuels marketing business in Greece and retail churn in the 
US, Europe and Australasia. Further proceeds from the sale of LukArco 
were received in 2011.

 a 2011 included a charge of $700 million associated with the termination of the agreement to sell our 
60% interest in Pan American Energy LLC to Bridas Corporation (see page 85).
 b 2009 included $1,579 million in relation to the impairment of goodwill allocated to the US West 
Coast fuels value chain.
 c Relates to an embedded derivative arising from a financing arrangement.
 d 2011 included charges of $687 million in relation to raw materials purchase contracts associated 
with our exit from the solar business.
 e Finance costs relate to the Gulf of Mexico oil spill. See Financial statements – Note 2 on page 190 
for further details.
 f Tax is calculated by applying discrete quarterly effective tax rates (excluding the impact of the Gulf 
of Mexico oil spill and, for 2011, the impact of a $683-million one-off deferred tax adjustment in 
respect of an increase in the supplementary charge on UK oil and gas production) on group profit 
or loss. However, the US statutory tax rate has been used for recoveries relating to the Gulf of 
Mexico oil spill and expenditures that qualify for tax relief. In 2009, no tax credit was calculated on 
the goodwill impairment in Refining and Marketing because the charge is not tax deductible.

Non-GAAP information on fair value accounting effects
The impacts of fair value accounting effects, relative to management’s 
internal measure of performance, and a reconciliation to GAAP information

Business reviewRisk factors

We urge you to consider carefully the risks described below. The potential 
impact of their occurrence could be for our business, financial condition 
and results of operations to suffer (including through the failure to achieve 
our current strategic priorities (see ‘10-point plan’ – pages 38-39)) and the 
trading price and liquidity of our securities to decline.

Our system of risk management identifies and provides the 

response to risks of group significance through the establishment of 
standards and other controls. Any failure of this system could lead to the 
occurrence, or re-occurrence, of any of the risks described below and a 
consequent material adverse effect on BP’s business, financial position, 
results of operations, competitive position, cash flows, prospects, liquidity, 
shareholder returns and/or implementation of its strategic agenda.

The risks are categorized against the following areas: strategic; 

compliance and control; and safety and operational. In addition, we have 
also set out two further risks for your attention – those resulting from the 
2010 Gulf of Mexico oil spill (the Incident) and those related to the general 
macroeconomic outlook.

The Gulf of Mexico oil spill has had and could continue to have a 
material adverse impact on BP.
There is significant uncertainty in the extent and timing of costs and 
liabilities relating to the Incident, the impact of the Incident on our 
reputation and the resulting possible impact on our licence to operate 
including our ability to access new opportunities. There is also significant 
uncertainty regarding potential changes in applicable regulations and 
the operating environment that may result from the Incident. These 
increase the risks to which the group is exposed and may cause our costs 
to increase. These uncertainties are likely to continue for a significant 
period. Thus, the Incident has had, and could continue to have, a material 
adverse impact on the group’s business, competitive position, financial 
performance, cash flows, prospects, liquidity, shareholder returns and/or 
implementation of its strategic agenda, particularly in the US.

We recognized a pre-tax charge of $40.9 billion in 2010 and a pre-tax 

credit of $3.7 billion in 2011 as a result of the Incident. The total amounts 
that will ultimately be paid by BP in relation to all obligations relating to the 
Incident are subject to significant uncertainty and the ultimate exposure and 
cost to BP will be dependent on many factors. Furthermore, the amount 
of claims that become payable by BP, the amount of fines ultimately 
levied on BP (including any potential determination of BP’s negligence 
or gross negligence), the outcome of litigation, the amount and timing of 
payments under any settlements, and any costs arising from any longer-
term environmental consequences of the oil spill, will also impact upon the 
ultimate cost for BP. Although the provision recognized is the current best 
estimate of expenditures required to settle certain present obligations at the 
end of the reporting period, there are future expenditures for which it is not 
possible to measure the obligation reliably. The risks associated with the 
Incident could also heighten the impact of the other risks to which the group 
is exposed as further described below.

The general macroeconomic outlook can affect BP’s results given the 
nature of our business.
In the continuing uncertain financial and economic environment, certain 
risks may gain more prominence either individually or when taken together. 
Oil and gas prices can be very volatile, with average prices and margins 
influenced by changes in supply and demand. This is likely to exacerbate 
competition in all businesses, which may impact costs and margins. 
At the same time, governments are facing greater pressure on public 
finances, which may increase their motivation to intervene in the fiscal 
and regulatory frameworks of the oil and gas industry, including the risk of 
increased taxation, nationalization and expropriation. The global financial 
and economic situation may have a negative impact on third parties with 
whom we do, or may do, business. In particular, ongoing instability in or a 
collapse of the eurozone could trigger a new wave of financial crises and 
push the world back into recession, leading to lower demand and lower oil 
and gas prices. Any of these factors may affect our results of operations, 
financial condition, business prospects and liquidity and may result in a 
decline in the trading price and liquidity of our securities.

Capital markets are subject to volatility amid concerns over the European 
sovereign debt crisis and the slow-down of the global economy. If there 
are extended periods of constraints in these markets, or if we are unable 
to access the markets, including due to our financial position or market 
sentiment as to our prospects, at a time when cash flows from our 
business operations may be under pressure, our ability to maintain our 
long-term investment programme may be impacted with a consequent 
effect on our growth rate, and may impact shareholder returns, including 
dividends and share buybacks, or share price. Decreases in the funded 
levels of our pension plans may also increase our pension funding 
requirements.

Strategic risks
Access and renewal – BP’s future hydrocarbon production depends 
on our ability to renew and reposition our portfolio. Increasing 
competition for access to investment opportunities, the effects 
of the Gulf of Mexico oil spill on our reputation and cash flows, 
and more stringent regulation could result in decreased access to 
opportunities globally.
Successful execution of our group strategy depends on implementing 
activities to renew and reposition our portfolio. The challenges to renewal 
of our upstream portfolio are growing due to increasing competition for 
access to opportunities globally among both national and international oil 
companies, and heightened political and economic risks in certain countries 
where significant hydrocarbon basins are located. Lack of material 
positions in new markets could impact our future hydrocarbon production.

Moreover, the Gulf of Mexico oil spill has damaged BP’s reputation, 

which may have a long-term impact on the group’s ability to access new 
opportunities, both in the US and elsewhere. Adverse public, political 
and industry sentiment towards BP, and towards oil and gas drilling 
activities generally, could damage or impair our existing commercial 
relationships with counterparties, partners and host governments and 
could impair our access to new investment opportunities, exploration 
properties, operatorships or other essential commercial arrangements 
with potential partners and host governments, particularly in the US. In 
addition, responding to the Incident has placed, and will continue to place, 
a significant burden on our cash flow over the next several years, which 
could also impede our ability to invest in new opportunities and deliver 
long-term growth.

More stringent regulation of the oil and gas industry generally, and 
of BP’s activities specifically, arising from the Incident, could increase this 
risk.

Prices and markets – BP’s financial performance is subject to 
the fluctuating prices of crude oil and gas as well as the volatile 
prices of refined products and the profitability of our refining and 
petrochemicals operations.
Oil, gas and product prices are subject to international supply and 
demand. Political developments and the outcome of meetings of OPEC 
can particularly affect world supply and oil prices. Previous oil price 
increases have resulted in increased fiscal take, cost inflation and more 
onerous terms for access to resources. As a result, increased oil prices 
may not improve margin performance. In addition to the adverse effect 
on revenues, margins and profitability from any fall in oil and natural 
gas prices, a prolonged period of low prices or other indicators would 
lead to further reviews for impairment of the group’s oil and natural gas 
properties. Such reviews would reflect management’s view of long-term 
oil and natural gas prices and could result in a charge for impairment 
that could have a significant effect on the group’s results of operations 
in the period in which it occurs. Rapid material or sustained change in 
oil, gas and product prices can impact the validity of the assumptions on 
which strategic decisions are based and, as a result, the ensuing actions 
derived from those decisions may no longer be appropriate. A prolonged 
period of low oil prices may impact our ability to maintain our long-term 
investment programme with a consequent effect on our growth rate and 
may impact shareholder returns, including dividends and share buybacks, 
or share price. Periods of global recession could impact the demand for our 
products, the prices at which they can be sold and affect the viability of the 
markets in which we operate.

BP Annual Report and Form 20-F 2011    59

Business review:  BP in more depthBusiness reviewRefining profitability can be volatile, with both periodic over-supply and 
supply tightness in various regional markets, coupled with fluctuations 
in demand. Sectors of the petrochemicals industry are also subject to 
fluctuations in supply and demand, with a consequent effect on prices and 
profitability.

Climate change and carbon pricing – climate change and carbon 
pricing policies could result in higher costs and reduction in future 
revenue and strategic growth opportunities.
Compliance with changes in laws, regulations and obligations relating 
to climate change could result in substantial capital expenditure, taxes, 
reduced profitability from changes in operating costs, and revenue 
generation and strategic growth opportunities being impacted. Our 
commitment to the transition to a lower-carbon economy may create 
expectations for our activities, and the level of participation in alternative 
energies carries reputational, economic and technology risks.

Socio-political – the diverse nature of our operations around the 
world exposes us to a wide range of political developments and 
consequent changes to the operating environment, regulatory 
environment and law.
We have operations, and are seeking new opportunities, in countries 
where political, economic and social transition is taking place. Some 
countries have experienced, or may experience in the future, political 
instability, changes to the regulatory environment, changes in taxation, 
expropriation or nationalization of property, civil strife, strikes, acts of 
war and insurrections. Any of these conditions occurring could disrupt or 
terminate our operations, causing our development activities to be curtailed 
or terminated in these areas, or our production to decline, could limit our 
ability to pursue new opportunities and could cause us to incur additional 
costs. In particular, our investments in the US, Russia, Iraq, Egypt, Libya, 
Bolivia, Argentina and other countries could be adversely affected by 
heightened political and economic environment risks. See pages 34-35 for 
information on the locations of our major assets and activities.

We set ourselves high standards of corporate citizenship and aspire 

to contribute to a better quality of life through the products and services 
we provide. If it is perceived that we are not respecting or advancing the 
economic and social progress of the communities in which we operate, our 
reputation and shareholder value could be damaged.

Competition – BP’s group strategy depends upon continuous 
innovation in a highly competitive market.
The oil, gas and petrochemicals industries are highly competitive. There 
is strong competition, both within the oil and gas industry and with other 
industries, in supplying the fuel needs of commerce, industry and the 
home. Competition puts pressure on product prices, affects oil products 
marketing and requires continuous management focus on reducing unit 
costs and improving efficiency, while ensuring safety and operational 
risk is not compromised. The implementation of group strategy requires 
continued technological advances and innovation including advances in 
exploration, production, refining, petrochemicals manufacturing technology 
and advances in technology related to energy usage. Our performance 
could be impeded if competitors developed or acquired intellectual 
property rights to technology that we required or if our innovation lagged 
the industry.

Investment efficiency – poor investment decisions could negatively 
impact our business.
Our organic growth is dependent on creating a portfolio of quality options 
and investing in the best options. Ineffective investment selection and 
development could lead to loss of value and higher capital expenditure.

Reserves replacement – inability to progress upstream resources in a 
timely manner could adversely affect our long-term replacement of 
reserves and negatively impact our business.
Successful execution of our group strategy depends critically on sustaining 
long-term reserves replacement. If upstream resources are not progressed 
in a timely and efficient manner, we will be unable to sustain long-term 
replacement of reserves.

60    BP Annual Report and Form 20-F 2011

Liquidity, financial capacity and financial exposure – failure to operate 
within our financial framework could impact our ability to operate 
and result in financial loss. Exchange rate fluctuations can impact our 
underlying costs and revenues.
The group seeks to maintain a financial framework to ensure that it is 
able to maintain an appropriate level of liquidity and financial capacity. This 
framework constrains the level of assessed capital at risk for the purposes 
of positions taken in financial instruments. Failure to accurately forecast or 
maintain sufficient liquidity and credit to meet these needs could impact 
our ability to operate and result in a financial loss. Commercial credit risk is 
measured and controlled to determine the group’s total credit risk. Inability 
to determine adequately our credit exposure could lead to financial loss. A 
credit crisis affecting banks and other sectors of the economy could impact 
the ability of counterparties to meet their financial obligations to the group. 
It could also affect our ability to raise capital to fund growth and to meet 
our obligations. The change in the group’s financial framework during 2010 
to make it more prudent may not be sufficient to avoid a substantial and 
unexpected cash call.

BP’s clean-up costs and potential liabilities resulting from pending 

and future claims, lawsuits, settlements and enforcement actions 
relating to the Gulf of Mexico oil spill, together with the potential cost of 
implementing remedies sought in the various proceedings, cannot be fully 
estimated at this time but they have had, and could continue to have, a 
material adverse impact on the group’s business, competitive position, 
financial performance, cash flows, prospects, liquidity, shareholder 
returns and/or implementation of its strategic agenda, particularly in the 
US. Furthermore, we recognized a pre-tax charge of $40.9 billion in 2010 
and a pre-tax credit of $3.7 billion in 2011, and further potential liabilities 
may continue to have a material adverse effect on the group’s results of 
operations and financial condition. See Financial statements – Note 2 on 
pages 190-194 and Legal proceedings on pages 160-166. More stringent 
regulation of the oil and gas industry arising from the Incident, and of BP’s 
activities specifically, could increase this risk.

Crude oil prices are generally set in US dollars, while sales of 
refined products may be in a variety of currencies. Fluctuations in exchange 
rates can therefore give rise to foreign exchange exposures, with a 
consequent impact on underlying costs and revenues.

See Financial statements – Note 26 on page 217 for more 

information on financial instruments and financial risk factors.

Insurance – BP’s insurance strategy means that the group could, 
from time to time, be exposed to material uninsured losses which 
could have a material adverse effect on BP’s financial condition and 
results of operations.
In the context of the limited capacity of the insurance market, many 
significant risks are retained by BP. The group generally restricts its 
purchase of insurance to situations where this is required for legal or 
contractual reasons. This means that the group could be exposed to 
material uninsured losses, which could have a material adverse effect 
on its financial condition and results of operations. In particular, these 
uninsured costs could arise at a time when BP is facing material costs 
arising out of some other event which could put pressure on BP’s liquidity 
and cash flows. For example, BP has borne and will continue to bear the 
entire burden of its share of any property damage, well control, pollution 
clean-up and third-party liability expenses arising out of the Gulf of Mexico 
oil spill.

Compliance and control risks
Regulatory – the oil industry in general, and in particular the US 
industry following the Gulf of Mexico oil spill, faces increased 
regulation that could increase the cost of regulatory compliance and 
limit our access to new exploration properties.
After the Gulf of Mexico oil spill, it is likely that there will be more stringent 
regulation of oil and gas activities in the US and elsewhere, particularly 
relating to environmental, health and safety controls and oversight of 
drilling operations, as well as access to new drilling areas. Regulatory or 
legislative action may impact the industry as a whole and could be directed 
specifically towards BP. The US government imposed a moratorium on 
certain offshore drilling activities, which was subsequently lifted in October 

Business review2010. Similar actions may be taken by governments elsewhere in the 
world. New regulations and legislation, as well as evolving practices, could 
increase the cost of compliance and may require changes to our drilling 
operations, exploration, development and decommissioning plans, and 
could impact our ability to capitalize on our assets and limit our access to 
new exploration properties or operatorships, particularly in the deepwater 
Gulf of Mexico. In addition, increases in taxes, royalties and other amounts 
payable to governments or governmental agencies, or restrictions on 
availability of tax relief, could also be imposed as a response to the 
Incident.

In addition, the oil industry is subject to regulation and intervention 

by governments throughout the world in such matters as the award of 
exploration and production interests, the imposition of specific drilling 
obligations, environmental, health and safety controls, controls over the 
development and decommissioning of a field (including restrictions on 
production) and, possibly, nationalization, expropriation, cancellation or 
non-renewal of contract rights. We buy, sell and trade oil and gas products 
in certain regulated commodity markets. Failure to respond to changes 
in trading regulations could result in regulatory action and damage to our 
reputation. The oil industry is also subject to the payment of royalties and 
taxation, which tend to be high compared with those payable in respect 
of other commercial activities, and operates in certain tax jurisdictions that 
have a degree of uncertainty relating to the interpretation of, and changes 
to, tax law. As a result of new laws and regulations or other factors, we 
could be required to curtail or cease certain operations, or we could incur 
additional costs.

See pages 107-110 for more information on environmental 

regulation.

Ethical misconduct and non-compliance – ethical misconduct or 
breaches of applicable laws by our employees could be damaging to 
our reputation and shareholder value.
Our code of conduct, which applies to all employees, defines our 
commitment to integrity, compliance with all applicable legal requirements, 
high ethical standards and the behaviours and actions we expect of our 
businesses and people wherever we operate. Our renewed values, 
which were launched in 2011, are intended to guide the way we and our 
employees behave and do business. Incidents of ethical misconduct or 
non-compliance with applicable laws and regulations, including non-
compliance with anti-bribery, anti-corruption and other applicable laws 
could be damaging to our reputation and shareholder value. Multiple events 
of non-compliance could call into question the integrity of our operations. 
For example, in our trading businesses, there is the risk that a determined 
individual could operate as a ‘rogue trader’, acting outside BP’s delegations, 
controls or code of conduct and in contravention of our renewed values in 
pursuit of personal objectives that could be to the detriment of BP and its 
shareholders.

For certain legal proceedings involving the group, see Legal 
proceedings on pages 160-166. For further information on the risks 
involved in BP’s trading activities, see Operational risks – Treasury and 
trading activities on page 63.

Liabilities and provisions – BP’s potential liabilities resulting from 
pending and future claims, lawsuits, settlements and enforcement 
actions relating to the Gulf of Mexico oil spill, together with the 
potential cost and burdens of implementing remedies sought in the 
various proceedings, cannot be fully estimated at this time but they 
have had, and are expected to continue to have, a material adverse 
impact on the group’s business.
Under the Oil Pollution Act of 1990 (OPA 90), BP Exploration & Production 
Inc. is one of the parties financially responsible for the clean-up of the Gulf 
of Mexico oil spill and for certain economic damages as provided for in 
OPA 90, as well as certain natural resource damages associated with the 
spill and certain costs determined by federal and state trustees engaged in 
a joint assessment of such natural resource damages.

BP and certain of its subsidiaries have also been named as 

defendants in numerous lawsuits in the US arising out of the Incident, 
including actions for personal injury and wrongful death, purported class 
actions for commercial or economic injury, actions for breach of contract, 

violations of statutes, property and other environmental damage, securities 
law claims and various other claims. See Legal proceedings on pages 
160-166.

BP is subject to a number of investigations related to the Incident 

by numerous federal and State agencies. See Legal proceedings on pages 
160-166. The types of enforcement action pursued and the nature of the 
remedies sought will depend on the discretion of the prosecutors and 
regulatory authorities and, in some circumstances, their assessment of 
BP’s culpability, if any, following their investigations. Such enforcement 
actions could include criminal proceedings against BP and/or employees 
of the group. In addition to fines and penalties, such enforcement actions 
could result in the suspension of operating licences and debarment from 
government contracts. Debarment of BP Exploration & Production Inc. 
would prevent it from bidding on or entering into new federal contracts or 
other federal transactions, and from obtaining new orders or extensions 
to existing federal contracts, including federal procurement contracts or 
leases. Dependent on the circumstances, debarment or suspension may 
also be sought against affiliated entities of BP Exploration & Production 
Inc. Although BP believes that there are costs arising out of the spill that 
are recoverable from its partners and other parties responsible under OPA 
90, and although settlements have been agreed during 2011 with both 
partners, one contractor, and the manufacturer of the blowout preventer at 
the Macondo well, further recoveries are not certain and so have not been 
recognized in the financial statements (see Financial statements – Note 2 
on pages 190-194).

Any finding of gross negligence for purposes of penalties sought 
against the group under the Clean Water Act would also have a material 
adverse impact on the group’s reputation, would affect our ability to 
recover costs relating to the Incident from other parties responsible under 
OPA 90 and could affect the fines and penalties payable by the group with 
respect to the Incident under enforcement actions outside the Clean Water 
Act context.

The Gulf of Mexico oil spill has damaged BP’s reputation. This, 

combined with other past events in the US (including the 2005 explosion 
at the Texas City refinery and the 2006 pipeline leaks in Alaska), may lead 
to an increase in the number of citations and/or the level of fines imposed 
in relation to the Gulf of Mexico oil spill and any future alleged breaches of 
safety or environmental regulations.

Claims by individuals and businesses under OPA 90’s claims 

process have been administered by the Gulf Coast Claims Facility (GCCF) 
headed by Kenneth Feinberg, who was appointed jointly by BP and the 
US Administration. The proposed economic loss settlement reached with 
the Plaintiffs’ Steering Committee (PSC), acting on behalf of individual and 
business plaintiffs in MDL 2179, provides for a transition from the GCCF. A 
court-supervised transitional claims process for economic loss claims will be 
in operation while the infrastructure for the new settlement claims process 
is put in place. During this transitional period, the processing of claims that 
have been submitted to the GCCF will continue, and new claimants may 
submit their claims. 

The proposed settlement is subject to final written agreement and 

court approvals and payments under the proposed settlement, and any 
other payments that may be made by BP in respect of any other individual 
and business claims under OPA 90, could ultimately be higher than the 
amount for which we have recognized a provision. See Legal proceedings 
on pages 160-164 and Financial statements – Note 36 on pages 231-234.

Changes in external factors could affect our results of operations and 
the adequacy of our provisions.
We remain exposed to changes in the external environment, such as 
new laws and regulations (whether imposed by international treaty or by 
national or local governments in the jurisdictions in which we operate), 
changes in tax or royalty regimes, price controls, government actions to 
cancel or renegotiate contracts, market volatility or other factors. Such 
factors could reduce our profitability from operations in certain jurisdictions, 
limit our opportunities for new access, require us to divest or write-down 
certain assets or affect the adequacy of our provisions for pensions, tax, 
environmental and legal liabilities. Potential changes to pension or financial 
market regulation could also impact funding requirements of the group.

BP Annual Report and Form 20-F 2011    61

Business review:  BP in more depthBusiness reviewReporting – failure to accurately report our data could lead to 
regulatory action, legal liability and reputational damage.
External reporting of financial and non-financial data is reliant on the 
integrity of systems and people. Failure to report data accurately and in 
compliance with external standards could result in regulatory action, legal 
liability and damage to our reputation.

Safety and operational risks
The risks inherent in our operations include a number of hazards that, 
although many may have a low probability of occurrence, can have 
extremely serious consequences if they do occur, such as the Gulf of 
Mexico oil spill. The occurrence of any such risks could have a consequent 
material adverse impact on the group’s business, competitive position, 
cash flows, results of operations, financial position, prospects, liquidity, 
shareholder returns and/or implementation of the group’s strategic goals.

Process safety, personal safety and environmental risks – the nature 
of our operations exposes us to a wide range of significant health, 
safety, security and environmental risks, the occurrence of which 
could result in regulatory action, legal liability and increased costs 
and damage to our reputation.
The nature of the group’s operations exposes us to a wide range of 
significant health, safety, security and environmental risks. The scope of 
these risks is influenced by the geographic range, operational diversity 
and technical complexity of our activities. In addition, in many of our major 
projects and operations, risk allocation and management is shared with 
third parties, such as contractors, sub-contractors, joint venture partners 
and associates. See ‘Joint ventures and other contractual arrangements 
– BP may not have full operational control and may have exposure to 
counterparty credit risk and disruptions to our operations and strategic 
objectives due to the nature of some of its business relationships’ on 
page 63.

There are risks of technical integrity failure as well as risk of natural 

disasters and other adverse conditions in many of the areas in which we 
operate, which could lead to loss of containment of hydrocarbons and 
other hazardous material, as well as the risk of fires, explosions or other 
incidents.

In addition, inability to provide safe environments for our workforce 

and the public could lead to injuries or loss of life and could result in 
regulatory action, legal liability and damage to our reputation.

Our operations are often conducted in difficult or environmentally 

sensitive locations, in which the consequences of a spill, explosion, 
fire or other incident could be greater than in other locations. These 
operations are subject to various environmental and safety laws, 
regulations and permits and the consequences of failure to comply 
with these requirements can include remediation obligations, penalties, 
loss of operating permits and other sanctions. Accordingly, inherent in 
our operations is the risk that if we fail to abide by environmental and 
safety and protection standards, such failure could lead to damage to the 
environment and could result in regulatory action, legal liability, material 
costs, damage to our reputation or denial of our licence to operate.
To help address health, safety, security, environmental and 

operations risks, and to provide a consistent framework within which 
the group can analyse the performance of its activities and identify 
and remediate shortfalls, BP has introduced a group-wide operating 
management system (OMS). Work on the application of OMS in individual 
operating businesses continues and following the Gulf of Mexico oil spill 
an enhanced safety and operational risk (S&OR) function was established, 
reporting directly to the group chief executive. There can be no assurance 
that OMS will adequately identify all process safety, personal safety and 
environmental risk or provide the correct mitigations, or that all operations 
will be in conformance with OMS at all times.

Security – hostile activities against our staff and activities could 
cause harm to people and disrupt our operations.
Security threats require continuous oversight and control. Acts of terrorism, 
piracy, sabotage, cyber-attacks and similar activities directed against our 
operations and offices, pipelines, transportation or computer systems could 
cause harm to people and could severely disrupt business and operations. 

62    BP Annual Report and Form 20-F 2011

Our business activities could also be severely disrupted by civil strife and 
political unrest in areas where we operate.

Product quality – failure to meet product quality standards could lead 
to harm to people and the environment and loss of customers.
Supplying customers with on-specification products is critical to 
maintaining our licence to operate and our reputation in the marketplace. 
Failure to meet product quality standards throughout the value chain could 
lead to harm to people and the environment and loss of customers.

Drilling and production – these activities require high levels 
of investment and are subject to natural hazards and other 
uncertainties. Activities in challenging environments heighten many 
of the drilling and production risks including those of integrity 
failures, which could lead to curtailment, delay or cancellation 
of drilling operations, or inadequate returns from exploration 
expenditure.
Exploration and production require high levels of investment and are 
subject to natural hazards and other uncertainties, including those relating 
to the physical characteristics of an oil or natural gas field. Our exploration 
and production activities are often conducted in extremely challenging 
environments, which heighten the risks of technical integrity failure and 
natural disasters discussed above. The cost of drilling, completing or 
operating wells is often uncertain. We may be required to curtail, delay 
or cancel drilling operations because of a variety of factors, including 
unexpected drilling conditions, pressure or irregularities in geological 
formations, equipment failures or accidents, adverse weather conditions 
and compliance with governmental requirements. In addition, exploration 
expenditure may not yield adequate returns, for example in the case of 
unproductive wells or discoveries that prove uneconomic to develop. 
The Gulf of Mexico oil spill illustrates the risks we face in our drilling and 
production activities.

Transportation – all modes of transportation of hydrocarbons involve 
inherent and significant risks.
All modes of transportation of hydrocarbons involve inherent risks. An 
explosion or fire or loss of containment of hydrocarbons or other hazardous 
material could occur during transportation by road, rail, sea or pipeline. This 
is a significant risk due to the potential impact of a release on people and 
the environment and given the high volumes potentially involved.

Major project delivery – our group plan depends upon successful 
delivery of major projects, and failure to deliver major projects 
successfully could adversely affect our financial performance.
Successful execution of our group plan depends critically on implementing 
the activities to deliver the major projects over the plan period. Poor 
delivery of any major project that underpins production or production 
growth, including maintenance turnaround programmes, and/or a major 
programme designed to enhance shareholder value could adversely affect 
our financial performance. Successful project delivery requires, among 
other things, adequate engineering and other capabilities and therefore 
successful recruitment and development of staff is central to our plans. 
See ‘People and capability – successful recruitment and development of 
staff is central to our plans’ on page 63.

Digital infrastructure is an important part of maintaining our 
operations, and a breach of our digital security could result in serious 
damage to business operations, personal injury, damage to assets, 
harm to the environment, breaches of regulations, litigation, legal 
liabilities and reparation costs.
The reliability and security of our digital infrastructure are critical to 
maintaining the availability of our business applications, including the 
reliable operation of technology in our various business operations and 
the collection and processing of financial and operational data, as well as 
the confidentiality of certain third-party information. A breach of our digital 
security, either due to intentional actions or due to negligence, could cause 
serious damage to business operations and, in some circumstances, could 
result in injury to people, damage to assets, harm to the environment, 
breaches of regulations, litigation, legal liabilities and reparation costs.

Business reviewBusiness continuity and disaster recovery – the group must be able 
to recover quickly and effectively from any disruption or incident, as 
failure to do so could adversely affect our business and operations.
Contingency plans are required to continue or recover operations following 
a disruption or incident. Inability to restore or replace critical capacity to an 
agreed level within an agreed timeframe would prolong the impact of any 
disruption and could severely affect our business and operations.

Crisis management – crisis management plans are essential to 
respond effectively to emergencies and to avoid a potentially severe 
disruption in our business and operations.
Crisis management plans and capability are essential to deal with 
emergencies at every level of our operations. If we do not respond, or are 
perceived not to respond, in an appropriate manner to either an external or 
internal crisis, our business and operations could be severely disrupted.

People and capability – successful recruitment and development of 
staff is central to our plans.
Successful recruitment of new staff, employee training, development 
and long-term renewal of skills, in particular technical capabilities such 
as petroleum engineers and scientists, are key to implementing our 
plans. Inability to develop human capacity and capability, both across 
the organization and in specific operating locations, could jeopardize 
performance delivery.

In addition, significant management focus is required in responding 

to the Gulf of Mexico oil spill Incident. Although BP set up the Gulf Coast 
Restoration Organization to manage the group’s long-term response, key 
management and operating personnel will need to continue to devote 
substantial attention to responding to the Incident and to address the 
associated consequences for the group. The group relies on recruiting 
and retaining high-quality employees to execute its strategic plans and 
to operate its business. The Incident response has placed significant 
demands on our employees, and the reputational damage suffered by the 
group as a result of the Incident and any consequent adverse impact on our 
performance could affect employee recruitment and retention.

Treasury and trading activities – control of these activities depends 
on our ability to process, manage and monitor a large number of 
transactions. Failure to do this effectively could lead to business 
disruption, financial loss, regulatory intervention or damage to our 
reputation.
In the normal course of business, we are subject to operational risk around 
our treasury and trading activities. Control of these activities is highly 
dependent on our ability to process, manage and monitor a large number of 
complex transactions across many markets and currencies. Shortcomings 
or failures in our systems, risk management methodology, internal control 
processes or people could lead to disruption of our business, financial loss, 
regulatory intervention or damage to our reputation.

Following the Gulf of Mexico oil spill, Moody’s Investors Service, 

Standard and Poor’s and Fitch Ratings downgraded the group’s long-term 
credit ratings. Since that time, the group’s credit ratings have improved 
somewhat but are still lower than they were immediately before the Gulf 
of Mexico oil spill. The impact that a significant operational incident can 
have on the group’s credit ratings, taken together with the reputational 
consequences of any such incident, the ratings and assessments published 
by analysts and investors’ concerns about the group’s costs arising from 
any such incident, ongoing contingencies, liquidity, financial performance 
and volatile credit spreads, could increase the group’s financing costs and 
limit the group’s access to financing. The group’s ability to engage in its 
trading activities could also be impacted due to counterparty concerns 
about the group’s financial and business risk profile in such circumstances. 
Such counterparties could require that the group provide collateral or 
other forms of financial security for its obligations, particularly if the 
group’s credit ratings are downgraded. Certain counterparties for the 
group’s non-trading businesses could also require that the group provide 
collateral for certain of its contractual obligations, particularly if the group’s 
credit ratings were downgraded below investment grade or where a 
counterparty had concerns about the group’s financial and business risk 
profile following a significant operational incident. In addition, BP may be 

unable to make a drawdown under certain of its committed borrowing 
facilities in the event we are aware that there are pending or threatened 
legal, arbitration or administrative proceedings which, if determined 
adversely, might reasonably be expected to have a material adverse effect 
on our ability to meet the payment obligations under any of these facilities. 
Credit rating downgrades could trigger a requirement for the company to 
review its funding arrangements with the BP pension trustees. Extended 
constraints on the group’s ability to obtain financing and to engage in its 
trading activities on acceptable terms (or at all) would put pressure on the 
group’s liquidity. In addition, this could occur at a time when cash flows 
from our business operations would be constrained following a significant 
operational incident, and the group could be required to reduce planned 
capital expenditures and/or increase asset disposals in order to provide 
additional liquidity, as the group did following the Gulf of Mexico oil spill.

Joint ventures and other contractual arrangements – BP may not 
have full operational control and may have exposure to counterparty 
credit risk and disruptions to our operations and strategic objectives 
due to the nature of some of its business relationships.
Many of our major projects and operations are conducted through joint 
ventures or associates and through contracting and sub-contracting 
arrangements. These arrangements often involve complex risk allocation, 
decision-making processes and indemnification arrangements. In certain 
cases, we may have less control of such activities than we would have 
if BP had full operational control. Our partners may have economic or 
business interests or objectives that are inconsistent with or opposed to, 
those of BP, and may exercise veto rights to block certain key decisions 
or actions that BP believes are in its or the joint venture’s or associate’s 
best interests, or approve such matters without our consent. Additionally, 
our joint venture partners or associates or contractual counterparties 
are primarily responsible for the adequacy of the human or technical 
competencies and capabilities which they bring to bear on the joint project, 
and in the event these are found to be lacking, our joint venture partners 
or associates may not be able to meet their financial or other obligations to 
their counterparties or to the relevant project, potentially threatening the 
viability of such projects. Furthermore, should accidents or incidents occur 
in operations in which BP participates, whether as operator or otherwise, 
and where it is held that our sub-contractors or joint-venture partners 
are legally liable to share any aspects of the cost of responding to such 
incidents, the financial capacity of these third parties may prove inadequate 
to fully indemnify BP against the costs we incur on behalf of the joint 
venture or contractual arrangement. Should a key sub-contractor, such as 
a lessor of drilling rigs, be no longer able to make these assets available 
to BP, this could result in serious disruption to our operations. Where BP 
does not have operational control of a venture, BP may nonetheless still be 
pursued by regulators or claimants in the event of an incident.

Business review:  BP in more depthBusiness reviewBP sells lubricants in Cuba through a 50:50 joint venture and trades in 
small quantities of lubricants. BP sold small quantities of lubricants to third 
parties that were resold in Sudan; BP has terminated these sales.

BP has equity interests in non-operated joint ventures with air 

fuel sellers, re-sellers, and fuel delivery services around the world. From 
time to time, the joint venture operator may sell or deliver fuel to airlines 
from Sanctioned Countries or flights to Sanctioned Countries without 
BP’s knowledge or consent. BP has registered and paid required fees for 
patents and trademarks in Sanctioned Countries.

Further note on certain activities
During the period covered by this report, non-US subsidiaries or other 
non-US entities of BP conducted limited activities in, or with persons 
from, certain countries identified by the US Department of State as 
State Sponsors of Terrorism or otherwise subject to US sanctions 
(‘Sanctioned Countries’). These activities continue to be insignificant to 
the group’s financial condition and results of operations. In 2011, the US 
enacted additional sanctions against Iran which included lower monetary 
thresholds for certain investments in Iran for the development or refining 
of petroleum resources, new restrictions on the petrochemicals industry 
and restrictions on transactions with the Iran Central Bank, including 
financial transactions for the purchase of Iranian-origin crude oil. Further 
legislation is pending in the US Congress which may enact additional 
sanctions against Iran. The UK adopted sanctions prohibiting UK persons 
from engaging in any financial transactions with the Iran Central Bank 
or other financial institutions incorporated in Iran. Both the US and the 
EU enacted strong sanctions against Syria including a prohibition on the 
purchase of Syrian-origin crude and a US prohibition on the provision of 
services by US persons. (Libya sanctions were enacted in early 2011 and 
largely lifted by the end of the year.) In January 2012, the EU imposed an 
embargo on Iranian crude, among other measures, to be phased in over a 
period of months. The EU also adopted more stringent sanctions against 
Syria including a prohibition on supplying certain equipment used in the 
production, refining, or liquefaction of petroleum resources as well as 
restrictions on dealing with the Central Bank of Syria and numerous other 
Syrian financial institutions. BP monitors its activities with Sanctioned 
Countries and keeps them under review to ensure compliance with 
applicable laws and regulations of the US, the EU and other countries 
where BP operates.

BP has interests in, and is the operator of, two fields (the North 

Sea Rhum field and the Azerbaijan Shah Deniz field) and, serving the Shah 
Deniz field, a gas marketing entity and an entity that owns a gas pipeline 
(both entities and related assets located outside Iran), in which Naftiran 
Intertrade Co. Ltd (NICO) and NICO SPV Limited (collectively NICO) or 
Iranian Oil Company (UK) Limited (IOC UK) have interests. Production 
was suspended at the North Sea Rhum field (in which IOC UK has a 50% 
interest) in November 2010 and Rhum remains shut-in. It is presently 
unclear when it may be possible to resume production. The Shah Deniz 
field, its gas marketing entity and the entity that owns a pipeline (in which 
NICO has a 10% or less non-operating interest) continues in operation in 
full compliance with current US and EU sanctions. BP has no operations 
in Iran and does not purchase or ship crude oil or other products of Iranian 
origin. Joint venture participants in non-BP controlled or operated joint 
ventures may purchase Iranian-origin crude oil or other components 
as feedstock for facilities located outside the EU and US. BP does not 
sell crude oil or other products into Iran, except that small quantities of 
lubricants are sold to non-Iranian third parties for resale or use in Iran. Until 
January 2010, BP held an equity interest in an Iranian joint venture that 
blended and marketed lubricants for sale to domestic consumers in Iran. 
BP sold its equity interest but continues to sell small quantities of lubricant 
components to the current owner. Transactions with Iranian shipping 
companies have been terminated.

Following the imposition in 2011 of further US and EU sanctions 

against Syria, BP terminated all sales of crude oil and petroleum products 
into Syria, though continues to supply aviation fuel to non-governmental 
Syrian resellers outside of Syria. Prior to the imposition of Syrian sanctions 
in 2011, BP sold lubricants through third parties and obtained crude oil and 
refinery feedstocks for sale to third parties in Europe and for use in certain 
of its non-US refineries. BP also bought and sold crude oil and refined 
products into and from Syria and incurred port costs for vessels utilizing 
Syrian ports. Sales and purchases to and from Syrian shipping companies 
have been terminated.

Business reviewSafety

Over the past year, we have been developing and implementing a wide-
ranging programme to further enhance safety, risk management and 
compliance across BP. This programme was initiated in response to the 
Deepwater Horizon incident in the Gulf of Mexico in April 2010.

The programme emphasizes the continuing importance of personal 
and process safety within BP. Process safety involves applying good design 
principles, along with robust engineering, operating and maintenance 
practices, to managing operations safely. For BP, this means the plant 
is designed, maintained and operated properly to avoid failures such as 
spills or explosions that can result in injuries to people and impacts to 
the environment. It also means that employees and contractors have the 
appropriate training and competencies to carry out work, as well as observing 
applicable procedures and policies that help to prevent personal injury.

In 2011, BP reported two workforce fatalities, and we regret the 

loss of these lives. One was a rail-related fatality in the US, the other died 
as a result of an unauthorized transfer of fuel in South Africa.

Safety and operational risk
Safety management
Our safety and risk management approach is built on deep experience in 
the oil and gas industry. This includes learning from the recommendations 
of investigations into the Deepwater Horizon oil spill in 2010 and the Texas 
City refinery explosion in 2005, as well as operations audits, annual risk 
reviews, other incident investigations and from industry practice of sharing 
experience.

There are three key principles which we intend to be at the heart of 

our approach:
•	 Leadership fostering a culture where everyone is focused on safety, on 

managing and reducing risk and on safe, reliable and compliant 
operations.

•	 Our operating management system (OMS) being the way BP seeks to 

operate.

•	 Effective checks and balances independent of the business line and self- 

verification being carried out at all levels of the organization.

While we maintain our focus on processes, practices and protocols, we 
also place great emphasis on how our workforce applies them, thereby 
working to strengthen safety culture and workforce capability.

A dedicated function
We established the safety and operational risk (S&OR) function in early 
2011. S&OR supports the business line in delivering safe, reliable and 
compliant operations across the group’s operated businesses. It does this 
in four ways:
•	 It sets and updates the requirements, including those in OMS, that are 
used across the business for safety and operational risk management.
•	 It provides expert scrutiny of safety and operational risk, independent of 
line managers – advising, examining and providing assurance about what 
our operations do.

•	 It provides deep technical expertise to the operations.
•	 It has the authority to intervene and escalate issues to cause corrective 

action to be taken.

S&OR, as of the end of 2011, was made up of a central team of around 
300, as well as nearly 300 more who are deployed in BP’s businesses, 
providing guidance and scrutiny and examining how safety and operating 
risks are being assessed and managed on oil and gas production and 
drilling rigs, at refineries and across all our operations. The head of S&OR 
reports directly to the group chief executive.

The central team serves as the custodian of group requirements, 

runs safety and operational risk audit and capability programmes and 
endorses the appointment of individuals for designated safety-critical 
roles. The central team includes some of BP’s top engineers and safety 
specialists, several of whom have experience of other industries where 
major hazards have to be managed, including the military, nuclear energy 
and space exploration.

Our deployed S&OR teams work with our operating businesses – ranging 
from upstream oil and gas development and production to refineries, 
petrochemicals plants and retail networks. They help the businesses apply 
our standards to their operations and they help provide assurance to the 
group on how operational risks are being managed, business by business.

Operating businesses remain accountable for delivering safe, 
reliable and compliant operations. They have the responsibility of managing 
risks and bringing together people with the right skills and competencies. 
Working in collaboration with deployed S&OR subject specialists for 
guidance, they are subject to new levels of independent scrutiny and 
assurance.

Governance
BP reviews risks at all levels of the organization, with our S&OR function 
providing an independent view of safety and operational risk. While line 
managers are responsible for identifying and managing risks, we place 
strong emphasis on checks and balances, including both enhanced self-
verification by individual BP operations – such as drilling rigs or refineries 
– and independent assurance by the S&OR function.

The board’s safety, ethics and environment assurance committee 

(SEEAC) receives updates from the group chief executive and the head 
of S&OR on the work of the group operations risk committee (GORC), on 
BP’s performance in process and personal safety, and our monitoring of 
major incidents and near misses across the group. Where appropriate other 
senior managers will attend to provide briefings on safety, environmental 
and operational integrity in their areas of responsibility. SEEAC also 
receives information from the Independent Expert appointed to monitor 
the implementation of recommendations made by the BP US Refineries 
Independent Safety Review Panel following the 2005 explosion at our 
Texas City refinery. See Board performance report on pages 120-133 for 
further information on the activities of the board’s committees, including 
SEEAC and the Gulf of Mexico committee.

Lessons learned from major incidents are being incorporated 
into our operating management system and capability development 
programmes.

Operating management system
Launched in 2008, our operating management system (OMS) serves as 
our group-wide framework designed to drive a rigorous and systematic 
approach to safety, risk management, and operational integrity across the 
group. OMS integrates requirements regarding health, safety, security, 
environment, social responsibility and operational reliability, as well 
as related issues such as maintenance, contractor management and 
organizational learning, into a common system.

The principles and standards of OMS are supported by detailed 

group-wide practices, as well as other technical guidance materials. 
The goal of OMS is to apply certain standards, group-defined practices 
and group engineering technical practices on a group-wide basis in our 
operations; these include, among others, the practices on assessment, 
prioritization and management of risk; incident investigation; integrity 
management; and environmental and social requirements for major 
new projects.

Following the principle of continuous improvement, our OMS 

evolves over time, for example to reflect implementation experience as 
well as learnings from incident investigations, audits and risk assessments, 
and by strengthening mandatory practices.

Transitioning to OMS
The transition to OMS requires operations to develop a local OMS that 
describes how the operation addresses site-specific local operating risks, 
applies group standards and practices and manages compliance with 
applicable health, safety, security and environment legal requirements.  
As part of the transition, operations conduct a gap assessment against 
defined aspects of OMS and their local processes and procedures, and 
then develop a prioritized gap-closure plan. To formally transition to the 
system, operations issue a local OMS handbook for the workforce to 
follow, and complete a management-of-change document that details  
the changes involved.

BP Annual Report and Form 20-F 2011    65

Business review:  BP in more depthBusiness reviewAll of our operations, with the exception of those recently acquired, are 
now applying our OMS to govern their BP operations and have begun 
working to achieve conformance to standards and practices required by 
OMS through the performance improvement cycle process. This includes 
our global wells organization and global projects organization which were 
set up in 2011. See page 69 for information about joint ventures.

Conformance and continuous improvement
The application of a comprehensive management system such as OMS 
across a global company is an ongoing process. OMS defines the process 
for BP operations to apply and conform to required standards and practices 
on an ongoing basis, as well as to continuously improve their operational 
performance. Every year, after the initial gap assessment, as part of the 
annual performance improvement cycle each operating unit – for example, 
a region like the Gulf of Mexico in our upstream business, or a refinery in 
our downstream business – is required to conduct another gap assessment 
and to develop a further prioritized gap closure plan. These actions are risk-
prioritized and form an integral part of each operation’s annual and three-
year planning cycle. Where appropriate, actions are aggregated to provide 
common solutions. The results of these annual assessments are subject to 
review by S&OR.

Capability development
BP strives to equip its staff with the skills needed to apply the systems 
and processes to strengthen further our management of risk and process 
safety. We have provided extensive and focused training programmes for 
our operations personnel at all levels.

Training provision for operations personnel includes our operations 

academy programmes for senior management, delivered in partnership 
with the Massachusetts Institute of Technology, US; specialized 
operational and technical management programmes, for example courses 
in engineering and project management at the University of Manchester, 
UK; and process safety and management training for our front-line 
leaders, delivered under our Operations Essentials programme, which 
seeks to embed the BP way of operating as represented by our OMS. 
To date, approximately 24,000 managers, supervisors and technicians 
have attended at least one workshop within the operations essentials 
programme since 2008; additionally, more than 180,000 eLearning 
modules have been completed.

We communicate our expectations for qualified, competent and 
experienced contractor personnel through our procurement process and 
contractual provisions.

Safer drilling
Since the beginning of 2011, all BP-operated drilling and wells activity in 
the world has been conducted through a single global wells organization 
(GWO). By bringing functional wells expertise into a single organization 
with common global standards, we are working to standardize BP drilling 
and wells operations with the intent of delivering safe and compliant 
wells. GWO works with our safety and operational risk function with a 
view to reducing risk in drilling and so reduce the likelihood of an oil spill 
or incident occurring through prevention efforts. We also aim to reduce 
the consequences should an incident occur by focusing on containment, 
spill response, relief wells and crisis management. See Exploration and 
Production on page 80 for information about the upstream reorganization.

Oil spill prevention
We are implementing enhanced drilling safety standards across the 
organization.

Blowout preventers
We have issued standards for the maintenance, testing, verification and use 
of subsea blowout preventers (BOPs). For example, we require dynamically 
positioned drill rigs contracted by BP to have no fewer than two blind 
shear rams and a casing shear ram sitting within the blowout preventer 
to enhance its reliability in cutting the drill pipe and sealing the well in the 
event of a blowout or other operational emergency. We require third-party 
verification that testing and maintenance of our subsea BOPs are performed 

66    BP Annual Report and Form 20-F 2011

in accordance with industry recommended practice. In addition, BP requires 
that remotely operated vehicles can activate these BOPs in an emergency.

Cementing
We are enhancing oversight of cementing services by implementing new 
standards in cement design and testing. We have also strengthened the 
technical approval process for critical cementing operations, and have 
brought additional expertise into BP to oversee this. We are implementing 
quality audits of our cementing contractors’ laboratories.

Well start-up procedure
We have introduced a new well start-up procedure. The checklist covers 
a range of operational areas and verification of conformance is required 
by leaders from the business line and S&OR before operations can begin 
on certain wells and on new rigs. In one case, as a result of this process, 
BP rejected a contractor rig put forward by another operator due to it not 
meeting BP’s standards.

These requirements are designed to help identify and mitigate risks 
prior to contractors’ drilling rigs being put into service for BP. Interventions 
to date have included repairs to safety systems, additional training of 
personnel, modifications to equipment, verification of quality and inspection 
records, revised and clarified roles and responsibilities, enhanced training 
requirements, and enhanced risk management techniques.

See Environment and social responsibility section on pages 69-73 
for further information on BP’s approach to oil spill contingency planning 
and response.

Bly Report – internal investigation recommendations and actions taken
In the immediate aftermath of the Deepwater Horizon oil spill, BP launched 
an internal investigation, drawing on the expertise of more than 50 
technical and other specialists within BP and the industry. The investigation 
team was led by BP’s head of safety and operations, and worked 
independently from BP’s other spill response activities and organizations.

The BP investigation (the Bly Report) concluded that no single cause 

was responsible for the accident. The investigation instead found that a 
complex, inter-linked series of mechanical failures, human judgements, 
engineering design, operational implementation and team interfaces, 
involving several companies including BP, contributed to the accident.

The recommendations
As a result, the investigation team made 26 recommendations specific 
to drilling, which we accepted and are working to implement across our 
worldwide drilling operations. The recommendations include measures 
to improve contractor management, as well as to strengthen design and 
assurance on blowout preventers (BOPs), well control, pressure-testing for 
well integrity, emergency systems, cement testing, rig audit, verification, 
and personnel competence.

Interim measures
Shortly following the publication of the Bly Report, BP developed interim 
measures to immediately address the eight key findings contained 
within the report. An interim guidance document was issued to each of 
our 14 operating regions in December 2010 which contained specific 
requirements, including the well start-up check list. This guidance 
continues to be in effect across all BP drilling and completions operations. 
We continue to progress implementation of the recommendations from 
the Deepwater Horizon investigation report and that work will ultimately 
replace the interim guidance.

Implementing the recommendations
Implementing the 26 recommendations across the group requires 
detailed work and many activities – from creating new practices and 
guidance, training and testing appropriate staff, changing requirements and 
expectations of our contractors, and establishing verification processes to 
assure the changes are sustainably embedded. We have a team of around 
85 people working full-time on this.

A project of this scale takes time; we must work to assure that all 
actions are delivered to a high standard across all of our well operations, 
and independently verified by our S&OR audit or internal audit function.

Business reviewWe have estimated and communicated delivery timelines for each of the 
recommendations and will continue to provide periodic updates of our 
progress. These timelines are based on existing facts and circumstances 
and can shift due to complexity, resource availability and evolving 
regulatory requirements.

The BP board has identified an independent expert to provide 
further oversight and assurance regarding the implementation of the 
Bly Report recommendations. The independent expert’s engagement is 
expected to commence in the latter half of May 2012. 

Progress update
At the end of 2011, four of the Bly Report recommendations have been 
completed. These were:
•	 Recommendation 6: to propose a recommended practice for foam 

cementing to the American Petroleum Institute.

•	 Recommendation 8: to strengthen the technical authority’s role in 

cementing and zonal isolation.

•	 Recommendation 13: to strengthen our rig audit process to improve 
closure and verification of audit findings across the rigs we own and 
contract.

•	 Recommendation 14: to establish key performance indicators for well 

integrity, well control, and rig safety-critical equipment.

We continue to make progress on all of the remaining recommendations 
largely in line with our planned schedule, with a further 12 
recommendations expected to be completed in 2012. Progress is tracked 
in the quarterly HSE and operations integrity report supplied to the 
executive team. See bp.com/internalinvestigation for the full report and 
quarterly updates on progress.

External investigations
In addition, there have been a number of external investigations, including 
those of the National Commission on the BP Deepwater Horizon Oil Spill 
and Offshore Drilling (oilspillcommission.gov) and the Joint Investigation 
Team of the Bureau of Ocean Energy Management, Regulation and 
Enforcement and the United States Coast Guard  
(boemre.gov/ooc/press/2011/press0914.htm). These reports were 
consistent in their conclusions that the accident resulted from multiple 
causes and was due to the actions of multiple parties. We are committed 
to understanding the causes, impacts and implications of the Deepwater 
Horizon incident and to learn and act on lessons from it. As part of this 
commitment, BP is reviewing the recommendations from government and 
industry reports.

Capping and containment
We have developed a mobile deepwater well capping package that 
includes about 250 pieces of speciality equipment. Maintained in a 
constant state of readiness in Houston, it is designed to be deployed by 
air freight and arrive wherever it is needed in just a few days.

We also share capping and containment equipment with other 
operators in the Gulf of Mexico, through the Marine Well Containment 
Company, as well as with operators in the UK North Sea. Further, BP 
provided project management for the Oil and Gas UK Oil Spill Prevention 
and Response Advisory Group to develop a next generation well capping 
system, now available in Europe, and is one of nine companies working in 
the Subsea Well Response Project to enhance the industry’s capability to 
respond globally to subsea well control events.

Relief wells
In responding to the Gulf of Mexico oil spill, we drilled two relief wells. 
Prior to drilling a deepwater well, BP operations now have relief well plans 
in place with equipment identified that can be moved to the site if needed. 
This is of particular benefit in areas that do not have the same infrastructure 
and support as more active basins such as the Gulf of Mexico.

Oil spill preparedness
We continue to develop and assimilate lessons from the response to the 
Gulf of Mexico oil spill. In 2011, as a priority we incorporated many of 
these lessons into new technical requirements for BP operations that drill 

in deepwater. Conformance with these requirements is mandatory for all 
operations drilling in water deeper than 1,000 feet and is subject to a formal 
assessment and sign-off by technical experts, S&OR and senior leaders. 
During 2011, we began implementing these requirements in Angola, the 
North Sea, Brazil, the US and Egypt, where we have deepwater drilling 
active or planned for 2012.

Crisis management
Crisis management planning is essential to respond effectively to 
emergencies and to avoid a potentially severe disruption in our business 
and operations. The intention is to build on interim requirements introduced 
in 2011 for deepwater drilling to put in place group-wide practices for both 
oil spill preparedness and response and crisis management.

During the response, we updated our incident action plan – an 

operational crisis planning tool – every 12-24 hours, which allowed us to 
have recent information to aid decision making. This was made possible by 
developing a common operating picture (COP) which helped us collect and 
present information in a way that enabled faster, better-informed decisions. 
The COP created an integrated view across more than 200 different data 
types. It provided an instant, interactive picture of the spill status and the 
activities of all responders.

See Environmental and social responsibility on pages 69-73 for 

further information on BP’s approach to oil spill contingency planning and 
response.

Safer refining
We have been working hard to apply the lessons learned from the 
tragic accident in our Texas City refinery in 2005 and are committed to 
implementing the recommendations of the BP US Refineries Independent 
Safety Review Panel.

Systematic management
The core business of our refineries is the safe storage, handling and 
processing of hydrocarbons which involves systematic management of the 
associated operating risks. In seeking to manage these risks, measures are 
taken by our refineries to:
•	 Prevent loss of hydrocarbon containment, such as oil spills, through 

well-designed, maintained and operated equipment.

•	 Reduce the likelihood of ignition of any hydrocarbon releases which may 

occur through controlling ignition sources.

•	 Provide safe locations, emergency procedures and other mitigation 

measures in the event of a fire or explosion occurring.

For example, across our refining business we are spending more than 
$700 million to install safety shelters for individuals, move people further 
away from hydrocarbon containing equipment and reduce the number of 
vehicles in our sites.

In 2011, we enhanced and standardized a number of technical 
practices that we intend to implement across our refining business in 2012 
and 2013, including practices pertaining to:
•	 Control of work practices including rules for what work is done, who it is 

done by, where it is done, when it is done and how it is done.

•	 Isolation of equipment from hydrocarbon and other energy sources to 

safely allow maintenance.

•	 Design, operation, maintenance for instrumented systems throughout 
their lifecycle to reliably achieve or maintain a safe operating state if 
unacceptable or dangerous process conditions are detected.

•	 Procedures and equipment requirements to assure safe handling of 

hydrogen sulphide containing streams.

•	 Design and operation of existing fired heaters.
•	 Identifying operating limits for our processes and equipment.

Risk assessment, prioritization and management
In 2011, all refineries used a consistent methodology to identify risks and 
prioritize mitigation actions, including addressing low probability, high 
consequence scenarios. Action plans have been developed for each risk 
and reviewed by authorized line and S&OR leaders. A multi-year risk profile 
reduction plan has been approved for each refinery and, learning from

Safety performance
Oil spills and loss of primary containment
We monitor the integrity of our operations, tanks, vessels and pipelines 
used to produce, process and transport oil and other hydrocarbons – with 
the aim of preventing the loss of material from its primary containment. 
Accordingly, we record losses of material, including hydrocarbons, from our 
assets, and losses or spills that reach land or water.

The loss of primary containment metric below includes unplanned 

or uncontrolled releases from a tank, vessel, pipe, rail car or equipment 
used for containment or transfer within our operational boundary, excluding 
non-hazardous releases such as water.

The US government and third parties have announced various 
estimates of the flow rate or total volume of oil spilled from the Deepwater 
Horizon incident. The multi-district litigation beginning in 2012 in New 
Orleans will address the amount of oil spilled. See Financial statements – 
Note 36 on page 233 for information about the volume used to determine 
the estimated liabilities.

Process safety
BP uses a disciplined framework for managing the integrity of hazardous 
operating systems and processes. We apply a combination of good design 
principles, engineering, and operating and maintenance practices to help 
deliver process safety performance and we monitor the number of process 
safety events occurring across our operations. The recently introduced 
American Petroleum Institute RP-754 standard, which sets out leading 
and lagging process safety indicators, organized into different tiers is used 
as the basis for our internal process safety-related reporting. API tier 1 
process safety events are the losses of primary containment of greatest 
consequence – causing harm to a member of the workforce or costly 
damage to equipment, or exceeding defined quantities. Seventy-four tier 1 
process safety events were reported in BP in 2011.

Personal safety
BP reports publicly on its personal safety performance according to 
standard industry metrics. In 2011, our overall reported recordable injury 
frequency (RIF) was 0.36, compared with 0.61 in 2010 and 0.34 in 2009. 
Our reported day away from work case frequency (DAFWCF) in 2011 
was 0.090, compared with 0.193 in 2010 and 0.069 in 2009. The 2010 
group personal safety data was affected by the Gulf Coast response effort.

our review of all the plans, we are introducing additional requirements to 
enhance the mitigation of similar risks across our refining business.

Operational planning and controls
Each BP-operated entity develops an annual plan drawing on the output 
from the performance improvement cycle including the risk management 
process. The plan is prioritized with the aim of continually driving reductions 
in the level of risk at the sites. We plan our work taking account of the 
capacity needed to deliver the safety-related activities required.

Control of work has been an area of major focus in our refining 

business since 2008. We continue to see improvement in the execution 
of our maintenance planning, scheduling and work activities across our 
refining sites as the overall control of work process is better understood, 
learning shared and efficiency opportunities identified.

Competence and capability
Refinery leaders are experienced operations professionals with many 
years’ experience within the industry and have typically attended the BP 
Operations Academy. Each refinery, with S&OR direction and expertise, 
is developing a consistent competency framework against which safety 
critical roles are assessed. The US refineries completed process safety 
competency assessments of over 3,500 employees in safety-critical roles 
and developed gap closure plans in 2011.

A key element within this competency development plan is the 

development of high fidelity process simulators. These will be used to train 
operators via simulations to respond to low probability, high consequence 
scenarios, similar to methods used with airline pilots.

Measurement, evaluation and corrective action
Regional vice presidents conduct performance reviews at each refinery. 
We now use a set of common safety metrics that are standard across all 
sites to help us proactively identify opportunities for improvement.

A quarterly assurance process has been introduced to enable S&OR 

to develop an ongoing, independent view of OMS conformance by the 
sites. Each site is assessed on their OMS self-assessment processes, the 
strength of existing risk mitigations and progress on risk reduction plans. 
Periodic S&OR audits against OMS requirements provide valuable insights 
from experts outside the site and result in actions to close identified gaps.
In 2011, we strengthened and standardized our approach to 
incident learning in our refining business, issuing briefings and alerts 
on lessons learned from incidents and near misses and requiring each 
refinery to assure that similar risks are assessed and appropriate actions 
completed.

Reports of the US refineries’ Independent Expert
L. Duane Wilson was appointed in 2007 by the board as an Independent 
Expert to provide an objective assessment of BP’s progress in 
implementing the recommendations of the BP US Refineries Independent 
Safety Review Panel (the Panel) aimed at improving process safety 
performance at BP’s five US refineries. Mr Wilson is expected to deliver 
his fifth annual report in April 2012, and BP will publish it at bp.com/
independentexpert. As in prior years, BP will have an opportunity to review 
and comment on Mr Wilson’s draft report for factual accuracy, but he is 
solely responsible for the report’s ultimate content.

The Independent Expert conducts his assessment of BP’s 
implementation of the Panel’s recommendations both through sampling 
and in-depth monitoring, evaluation and confirmation. Mr Wilson visited 
each BP US refinery at least twice in 2011 and interviewed personnel at 
many levels in the organization. He also engaged regularly with senior and 
executive management, both within Refining and Marketing and our safety 
and operational risk function, to gauge implementation progress. Mr Wilson 
also reviews progress reports and other documentation from BP. These 
include implementation status reports, process safety performance 
reports, overtime reports (to monitor the potential for worker fatigue), open 
and overdue process safety action item reports, incident investigations 
reports and safety audit reports.

Business reviewWorking with partners and contractors
BP, like our industry peers, rarely works in isolation – we need to work with 
suppliers, contractors and partners to carry out our operations. In 2011, 
more than 55% of the 374 million hours worked by BP were carried out by 
contractors.

Our ability to fulfil our corporate responsibility depends in part 

on the conduct of our suppliers, contractors and partners. We address 
this in a variety of ways, from training and dialogue to confirming 
operational standards through legally binding agreements. When we select 
contractors, our due diligence is designed to identify safety, bribery and 
corruption, money laundering and trade sanctions risks. We expect our 
suppliers, contractors and partners to comply with legal requirements and 
operate consistently with the principles of our code of conduct when they 
work on our behalf.

Within our operating management system we have group-wide and 
business-specific requirements and practices for working with contractors. 
The objective is to provide assurance that goods, equipment and services 
provided by third parties meet contractual and BP requirements and 
that there is a consistent, shared understanding of responsibilities. For 
example, in our drilling operations, where we have evaluated differences 
between our own standards and those of contractors, we require bridging 
documents to be put in place. These define how two or more safety 
management systems co-exist to allow co-operation and co-ordination 
between BP and the contractor.

Contractor management review
Following the Deepwater Horizon oil spill, we began an in-depth review 
of contractor management practices, with the aim of documenting and 
learning from best practice throughout BP and across a number of sectors 
and industries that use contractors in potentially dangerous activities. We 
studied 21 major organizations in six different sectors – airlines, mining, 
construction, pharmaceuticals and chemicals, nuclear and space.

We found that these organizations working in potentially high-
risk arenas tended to have fewer and longer-lasting relationships with 
contractors, supported by shared structures and practices. Clearly 
defined responsibilities and decision rights at every stage of each process 
are needed to make contractor relationships work – including training, 
monitoring and auditing. Rigorous qualification of suppliers, including 
competency assessments for critical roles, is also important.

The findings of this review are informing our contractor 
management approach, with initial work focusing on contracts in our 
upstream supply chain that involve potentially high-consequence activities.

Our partners in joint ventures
We seek to work in partnership with companies that share our 
commitment to ethical and sustainable working practices. However, in 
some of our joint ventures, we do not directly control how our partners and 
their employees approach these issues.

Typically, our level of influence or control over a project or operation 

is linked to the size of our financial stake compared to other participants. 
In some joint ventures we act as the operator. Where we are the operator, 
and where legal and contractual arrangements allow, our policies, 
standards and operating systems apply.

In other cases, for example where one of our partners is the 

designated operator or where the operator is a joint venture company 
owned by BP and other partners, we are not the day-to-day operator. In 
those cases our OMS provides for our businesses to consider whether 
the management system used by the operator provides similar levels of 
risk and performance management to our own. We seek to influence our 
partners through dialogue and constructive engagement.

In 2011, BP initiated a review into our approach to the management 
of our relationships with non-operated joint venture operators and partners. 
This work includes safety and operational risk as well as bribery and 
corruption risk.

Environmental and social 
responsibility

The world’s demand for energy is increasing and our business of finding 
and producing some of that energy means we operate in increasingly 
diverse locations globally. Many of these locations have environmental and 
social sensitivities.

To BP, working responsibly means managing our impacts on the 

areas where we operate, and making this a core principle in all of our 
activities. From the initial planning stages of a new project through to 
its eventual decommissioning and any remediation work that follows, 
our operating management system (OMS) lays out the standards and 
processes required for environmentally and socially responsible operations.
Wherever we work, we strive to minimize our impact on the 

environment – whether to land, air, water or wildlife – and to ensure that 
local people are engaged, human rights are respected and cultural heritage 
is conserved.

Our environmental and social practices
We are taking an increasingly systematic approach to the management of 
the environmental and social impacts of our projects. Our environmental 
and social practices, which form part of our OMS, set out how the major 
projects to which they apply should identify and manage environmental 
and social impacts. The practices also apply to projects that involve new 
access, projects that could affect an international protected area and some 
BP acquisition negotiations.

The practices help us deliver on the intent of the relevant sections 

of the OMS, the BP code of conduct and on our external commitments. 
They include several key requirements on impact assessment, security 
and human rights, indigenous people, international protected areas, 
greenhouse gas emissions, energy management, water management, 
ozone depleting substances, drilling wastes, and moving communities.

Early in the planning stage, applicable projects complete a screening 

process to identify environmental and social impacts that could arise from 
their activities. Between implementation in April 2010 and the end of 2011, 
nearly 60 projects had completed the screening process with the support 
of a trained and independent screening facilitator.

More information about our approach to environmental and 
social issues may be found in the BP Sustainability Review and on  
bp.com/sustainability.

Working in internationally protected areas
Our environmental and social practices require the projects to which they 
apply to understand the potential to affect international protected areas. 
The UNEP World Conservation Monitoring Centre’s World Database on 
Protected Areas is used to inform this screening process. Our international 
protected areas classification includes areas designated as protected by the 
International Union for the Conservation of Nature (categories I-IV), Ramsar 
and World Heritage sites, as well as areas proposed for protected status.
Where screening indicates that a proposed BP project may 

potentially affect an international protected area a high-level risk 
assessment is carried out. Our safety and operational risk function provides 
an independent review to inform the risk assessment, and before any 
physical activity begins permission is sought from senior management, 
together with appropriate mitigation measures. The Great Australian Bight 
Project completed this process in 2011.

Oil spill contingency planning and response
Applicable laws generally include requirements for dealing with the 
environmental and socio-economic impacts of oil spills or leaks. In some 
countries, regulators require as part of our licences to operate that plans 
are in place for responding to accidents and unplanned events such as 
oil spills.

BP Annual Report and Form 20-F 2011    69

Business review:  BP in more depthBusiness reviewThe Deepwater Horizon oil spill demanded a response at an order of 
magnitude never required before. We learned a great deal and made 
advances in response technology and systems. As a result we are updating 
our group requirements and are sharing our knowledge with the industry 
and regulators.

In 2012, we will be working on the development of enhanced 

oil spill preparedness and response requirements for all BP entities that 
handle oil in a way that gives rise to a risk of an oil spill. Once these 
requirements are incorporated into OMS, they will require relevant 
businesses to follow a planning process to predict how the spilled oil will 
behave; identify, assess and understand the environmental and social 
sensitivities at risk; define effective response strategies and confirm that 
appropriate response capabilities are in place. This practice will incorporate 
our deepwater technical requirements, further enabling a single, consistent 
process across BP.

Sensitivity mapping
Understanding the environmental and socio-economic sensitivities where 
we operate is an important part of planning for an effective response. We 
obtain sensitivity information from many sources, including environmental 
and social impact assessments (ESIAs) for many of our projects. These 
ESIAs include information about the potential environmental and socio-
economic impacts of planned activities and also the potential impacts that 
might occur in the event of an unplanned event, such as an oil spill. In 2011, 
we have used high resolution satellite imagery to enhance our sensitivity 
mapping across thousands of miles of coastlines, and submersibles to 
characterize the deep ocean. This has helped us better understand our 
environmental risks in regions like Angola, Brazil and the US.

Contingency planning
Identifying and assessing environmentally and socio-economically 
sensitive areas helps us to develop appropriate oil spill response and crisis 
management plans. The objective is to use response techniques to avoid 
or minimize the environmental and socio-economic impact of a spill to the 
extent feasible based upon an assessment of the sensitivity of the local 
environment. These plans are backed up by robust response ‘capability’, the 
tools and people required to mount an effective response to an incident.
How we work with designated government regulatory bodies in 
the event of a spill is critical. Sharing lessons learned and maintaining a 
dialogue with regulators in the regions where we operate is an important 
part of our approach. In many countries where BP operates, the regulator 
will ultimately determine the procedures to deal with the environmental and 
socio-economic impact.

Acute response plans are often focused on the physical 

containment and recovery of the spilled oil, though they also recognize that 
components in dispersed oil will be subject to processes of biodegradation, 
which may be facilitated and accelerated by the application of chemical 
dispersants.

For onshore operations, for example, BP refineries’ spill response 
plans include passive and active containment measures that are designed 
for the specific location and types of operations.

In the event of concurrent spills at multiple locations, each affected 

facility would activate its independent oil spill response plan and respond 
accordingly. Although responding to multiple spills of the same magnitude 
and complexity as occurred in the Gulf of Mexico in 2010 would be a 
challenge for the group, our response plans are not interdependent.

See Safety on pages 65-69 for further information on BP’s approach 

to oil spill prevention and preparedness.

Gulf of Mexico – our long-term commitments
See Gulf of Mexico oil spill on pages 76-79 for further information on 
BP’s response to the incident and environment and economic restoration 
efforts.

Canadian oil sands
Canada’s oil sands are believed to hold one of the world’s largest untapped 
supplies of oil, third in size to the resources in Saudi Arabia and Venezuela. 
BP is involved in three oil sands projects, all of which are located in the 
province of Alberta. Development of the Sunrise project, our joint venture 
operated by Husky Energy, is under way, with production from Phase 1 
expected to start in 2014. The other two proposed projects – Pike, which 
will be operated by Devon, and Terre de Grace, which will be BP-operated 
– are still in the early stages of development.

We reviewed and approved the decision to invest in Canadian oil 

sands projects, taking into consideration greenhouse gas (GHG) emissions, 
impacts on land, water use and local communities, and commercial 
viability. As with all joint ventures in which we are not the operator, we will 
monitor the progress of these projects and the mitigation of risk.
The extraction process to be used, in situ steam-assisted 

gravity drainage (SAGD) technology, involves the injection of steam 
underground. The steam liquefies the bitumen, allowing it to flow to the 
surface through production wells. This production technique reduces land 
disturbance and aligns to our strengths, particularly to our expertise with 
wells and improving large-scale reservoir performance. Unlike mining, 
in situ processes create a smaller physical footprint and do not involve 
tailing ponds.

A key concern around oil sands operations using SAGD is the 
amount of greenhouse gas emissions produced for steam generation 
and the processing of the produced bitumen. A ‘well-to-wheels’ study 
conducted in 2009, which measured total GHG emissions from production 
through to consumption, found the lifecycle emissions for oil sands-based 
products to be 5-15% higher than those from products from average crude 
oils consumed in the US.

Climate change
Climate change represents a significant challenge for society, the energy 
industry and BP. In response to the challenges and opportunities, BP is 
taking a number of practical steps, including investing in lower-carbon 
energy products such as biofuels and wind, and ventures focused on 
sustainable energy solutions; and seeking to manage our own GHG 
emissions through a focus on operational energy efficiency, reductions 
in flaring and venting and the engineering design for new projects. We 
see natural gas playing a key strategic role as a lower-carbon fuel that is 
increasingly secure and affordable. We also consider the potential impacts 
of a changing climate on our operations.

Greenhouse gas emissions
Our direct GHG emissionsa were 61.8 million tonnes (Mte) in 2011, 
compared with 64.9 Mte in 2010. This decrease of 3.1 Mte is primarily 
explained by the temporary reduction in activity in some of our businesses 
as a result of maintenance work and also by the sale of assets as part of 
our disposal programme. We achieved 0.2 Mte of sustainable emissions 
reductions in 2011.

Over the long-term it is likely that the carbon intensity of parts of 

our business will increase. In our upstream operations this is because 
we expect to move further into technically difficult and potentially more 
energy intensive areas. The intensity of certain refining operations may also 
increase with the trend towards processing heavier crudes which requires 
more energy.

In 2010 we did not report on GHG emissions associated with 

the Deepwater Horizon incident or response. We have since estimated 
the CO2 equivalent emissions from response activities in 2010 to be 
approximately 481,000 metric tonnes, which includes major vessels 
deployed. This figure does not include emissions associated with the 
‘vessels of opportunity programme’, the onshore vehicles and equipment 
and the incident itself, which are estimated to be minor. 

 a  We report GHG emissions on a CO2-equivalent basis, including CO2 and methane. This represents 
all consolidated entities and BP’s share of equity-accounted entities except TNK-BP.

70    BP Annual Report and Form 20-F 2011

Business reviewGreenhouse gas regulation
In the future, we expect that additional regulation of GHG emissions 
aimed at addressing climate change will have an increasing impact on 
our businesses, operating costs and strategic planning, but may also 
offer opportunities for the development of low-carbon technologies and 
businesses. See Regulation of the group’s business – Greenhouse gas 
regulation on page 109.

To help address potential future regulation, we factor a carbon cost 

into our investment appraisals and engineering designs for new projects. 
We do this by requiring larger projects, and those for which emissions 
costs would be a material part of the project, to apply a standard carbon 
cost to the projected GHG emissions over the life of the project. The 
standard cost is based on our estimate of the carbon price that might 
realistically be expected in particular parts of the world. In industrialized 
countries, this standard cost assumption is currently $40 per tonne of 
CO2 equivalent. We use this as a basis for assessing the economic value 
of the investment and as one consideration in optimizing the way the 
project is engineered with respect to emissions. This helps to assess our 
investments under scenarios in which the price of carbon emissions is 
higher than the current market price.

Adaptation to impacts resulting from a changing climate
We have funded research into the impacts of climate change on our 
operations for many years, to better understand the possible types of 
climate change impacts, potential effects on the environment and on our 
facilities and to develop potential responses to these impacts.

In the Beaufort Sea in Canada, for example, where BP is in the early 

stages of an oil exploration project, we have collaborated with ArcticNet, 
a local research organization devoted to understanding climate change 
impacts in the Arctic, on a two-year environmental baseline study. For 
ArcticNet the information gleaned will provide valuable data for analysis, 
while for BP the data will provide a useful baseline with which to compare 
future research, helping us to understand and chart the effects of climate 
change in this deepwater ocean environment.

Projects implementing our environmental and social practices are 
required to assess the potential impacts to the project from the changing 
climate. Any significant potential impacts identified are managed via the 
project’s risk management process. To support this risk assessment 
process, we continually update and improve our climate impact modelling 
tools. In the Caspian region, for example, we are working with meteorology 
and oceanology consultants to enhance the existing modelling capability 
and develop a regional climate model to provide long-term forecasts and 
trends of wind speed, wave height and sea level.

We also have a guide on adapting to a changing climate which is 

available for all projects and operations. This document sets out guidance 
to help businesses across BP make appropriate allowance for the potential 
effects of climate change.

For projects where climate change impacts are identified as a 

risk, our engineers typically seek to address them like any other physical 
and ecological hazard, rather than as a discrete category. We periodically 
review and adjust existing design criteria and engineering technology 
practices. For example, we adapt our drainage design practices based 
on the frequency and severity of storms as well as rainfall and runoff 
amounts; if storms are anticipated to become more frequent, or heavier, 
the engineering design will accommodate this.

Water
We are taking a more strategic approach to water use and assessing 
water-related risks within our businesses, including those associated with 
the growing global issue of water scarcity. Our focus is on increasing 
our ability to forecast, measure and manage emerging water risks and 
engaging with external organizations to better understand these risks and 
develop sustainable water management practices, particularly where water 
is scarce.

With our industry association IPIECA, BP has also participated in the 
development of a new customized oil and gas version of the World 
Business Council for Sustainable Development’s Global Water Tool, which 
helps oil and gas companies map their water use and assess risks of 
freshwater scarcity and related biodiversity impacts, across their portfolio 
of sites. BP has also invested in a water risk management tool, which is 
currently being piloted at a number of BP’s operations, to investigate the 
risks of water use and availability at a local level.

In the future, these tools will provide BP with a means of 
consistently defining water risks and opportunities across a number of 
our operations, enabling us to establish a more consistent approach to 
managing water issues throughout the group.

Hydraulic fracturing
Technology helps to make it possible for BP to extract unconventional gas 
resources safely and responsibly to help meet the growing global demand 
for gas. Unconventional gas can be classified into three categories: tight 
gas, coalbed methane and shale gas. BP is pursuing unconventional gas in 
the US and in other countries such as Algeria, Oman and Indonesia.

Hydraulic fracturing, or ‘fracking’, is a process of pumping water 

mixed with a small proportion of sand and chemicals underground at 
high pressure to fracture the rock and release gas that would otherwise 
not be accessible. Some stakeholders have expressed concerns about 
the potential environmental impacts. BP recognizes these concerns and 
seeks to apply responsible well design and construction, surface operation 
and fluid handling practices and engages constructively with government 
and industry to promote sound policies and regulation that protect water 
resources and the environment. We expect that many of the jurisdictions 
in which we operate will adopt stricter regulations governing ‘fracking’ and 
other unconventional gas extraction technologies in the future which could 
adversely affect our operations and profitability in our unconventional gas 
business.

BP continues to incur significant costs related to the 2010 Gulf of Mexico 
oil spill. Of the spill response cost of $586 million incurred in the year (2010 
$13,628 million) $336 million (2010 $1,043 million) remains as a provision 
at 31 December 2011.

The environmental remediation provision includes amounts 

for BP’s commitment to fund the Gulf of Mexico Research Initiative, 
natural resource damage (NRD) assessment costs and emergency NRD 
restoration projects. In addition, during the year BP entered a framework 
agreement with natural resource trustees for the United States and 
five Gulf Coast states, providing for up to $1 billion to be spent on early 
restoration projects to address natural resource injuries resulting from 
the Gulf of Mexico oil spill. Further amounts for spill response costs were 
provided during the year primarily to recognize increased costs of shoreline 
clean-up, patrolling and maintenance and vessel decontamination. The 
majority of the active clean-up of the shorelines had been completed by the 
end of the year.

See Financial statements – Note 2 on page 190, Note 36 on page 

231 and Note 43 on page 249 for further information relating to the Gulf of 
Mexico oil spill.

BP Annual Report and Form 20-F 2011    71

Business review:  BP in more depthBusiness reviewOperating and capital expenditure on the prevention, control, abatement 
or elimination of air, water and solid waste pollution is often not incurred 
as a separately identifiable transaction. Instead, it forms part of a larger 
transaction that includes, for example, normal maintenance expenditure. 
The figures for environmental operating and capital expenditure in the table 
are therefore estimates, based on the definitions and guidelines of the 
American Petroleum Institute.

Environmental operating expenditure of $704 million in 2011 was at 

a similar level to 2009 and 2010.

Similar levels of operating and capital expenditures are expected in 

the foreseeable future. 2011 capital expenditure was lower than in 2010 
due to the completion of various capital projects in our US refineries.

In addition to operating and capital expenditures, we also create 

provisions for future environmental remediation. Expenditure against such 
provisions normally occurs in subsequent periods and is not included in 
environmental operating expenditure reported for such periods.

Provisions for environmental remediation are made when a clean-
up is probable and the amount of the obligation can be reliably estimated. 
Generally, this coincides with the commitment to a formal plan of action or, 
if earlier, on divestment or on closure of inactive sites.

The extent and cost of future environmental restoration, 

remediation and abatement programmes are inherently difficult to 
estimate. They often depend on the extent of contamination, and 
the associated impact and timing of the corrective actions required, 
technological feasibility and BP’s share of liability. Though the costs of 
future programmes could be significant and may be material to the results 
of operations in the period in which they are recognized, it is not expected 
that such costs will be material to the group’s overall results of operations 
or financial position.

Additions to our environmental remediation provision increased in 
2011 largely due to changes in scope reassessments of the remediation 
plans of a number of our US retail sites. The charge for environmental 
remediation provisions in 2011 included $12 million in respect of provisions 
for new sites (2010 $54 million and 2009 $6 million).

In addition, we make provisions on installation of our oil- and 

gas-producing assets and related pipelines to meet the cost of eventual 
decommissioning. On installation of an oil or natural gas production facility 
a provision is established that represents the discounted value of the 
expected future cost of decommissioning the asset.

The level of increase in the decommissioning provision varies with 

We are a signatory to two voluntary agreements with implications for 
specific aspects of human rights: the UN Global Compact, which helps 
businesses align their operations and strategies with 10 principles, 
including some that are related to human rights, and the Voluntary 
Principles on Security and Human Rights, which define good practice for 
security operations in extractive industry companies. We have contributed 
to the work of oil and gas industry organization IPIECA’s human rights task 
force, which works on human rights issues and develops good practice 
guidance for companies in our industry.

In 2011 the UN Human Rights Council unanimously endorsed the 
Guiding Principles on Business and Human Rights. These outline specific 
responsibilities for businesses in relation to human rights. We participated 
in discussions on the development of the Guiding Principles, and in 2011 
we completed a comparison between our current policies and practices 
and the expectations in the Guiding Principles, to help us identify what 
work will be needed to achieve alignment with the principles.

BP’s code of conduct makes it clear that certain provisions, such 

as BP’s stance on the rights and dignity of communities, relate directly 
to human rights. See page 31 for further information about our code of 
conduct.

Revenue transparency and business ethics
As a member of the Extractive Industries Transparency Initiative (EITI), we 
work with governments, non-governmental organizations and international 
agencies to improve transparency in this area. In several countries that are 
in the process of becoming EITI compliant, BP is supporting the process; 
for example, BP is an active member of the Trinidad & Tobago EITI steering 
committee. In countries that have achieved EITI compliance, including 
Azerbaijan and Norway, BP submits an annual report on payments to their 
governments.

We have taken part in consultations in relation to new or proposed 

revenue transparency reporting requirements in the US and Europe for 
companies in the extractive industries. BP will fully comply with the 
appropriate mandatory regulations when they come into effect.

We are working to respond effectively to the standards flowing 
from the UK Bribery Act as well as other anti-corruption legislation such 
as the Foreign Corrupt Practices Act in the US. Bribery and corruption are 
serious risks in the oil and gas industry. Our code of conduct requires that 
our employees or others working on behalf of BP do not engage in bribery 
or corruption in any form in both the public and private sectors.

the number of new fields coming onstream in a particular year and the 
outcome of the periodic reviews. There was a significant increase in 2010, 
driven by activity in the Gulf of Mexico and this trend has continued in 
2011 as a result of changes in estimation and detailed reviews of expected 
future costs; the majority of the increase related to our sites in Trinidad, the 
Gulf of Mexico and the North Sea.

In 2011, we issued a group-wide anti-bribery and corruption 
standard, which applies to all BP employees and contractors. The standard 
requires annual bribery and corruption risk assessments; due diligence 
on all parties with whom BP does business; appropriate anti-bribery and 
corruption clauses in contracts and the training of personnel in anti-bribery 
and corruption measures.

On 15 October 2010, the Bureau of Ocean Energy Management, 

Regulation and Enforcement (BOEMRE) issued Notice to Lessees 
(NTL) 2010-G05, which requires that idle infrastructure on active 
leases is decommissioned earlier than previously was required and 
establishes guidelines to determine the future utility of idle infrastructure 
on active leases. As a consequence, the timing and methodology 
of well abandonment have changed, reflected in an increase to the 
decommissioning provision.

Additionally, we undertake periodic reviews of existing provisions. 

These reviews take account of revised cost assumptions, changes in 
decommissioning requirements and any technological developments.

Provisions for environmental remediation and decommissioning 

are usually set up on a discounted basis, as required by IAS 37 ‘Provisions, 
Contingent Liabilities and Contingent Assets’.

Further details of decommissioning and environmental provisions 

appear in Financial statements – Note 36 on page 231.

Respecting human rights
BP supports the Universal Declaration of Human Rights, which lays out the 
rights to which all human beings are entitled. We have also supported recent 
multi-stakeholder efforts to establish clear, universally-applicable guidelines 
on the responsibilities of businesses in relation to human rights issues.

Socio-economic development
We believe each BP project has the potential to benefit local communities 
by creating jobs, generating tax revenues and providing opportunities for 
local suppliers. Our presence in a location also has the potential to bring 
indirect economic benefits.

We run a range of programmes to build the skills of businesses 
in places where we work and to develop the local supply chain. These 
range from financing to sharing global standards and practice in areas such 
as health and safety. The programmes can benefit local companies by 
empowering them to reach the standards needed to supply BP and other 
clients. At the same time BP benefits from the local sourcing of goods and 
services.

BP’s social investments – the contributions we make to social and 
community programmes in locations where we operate – aim to support 
development programmes that we believe will seek to create a meaningful 
and sustainable impact – one that is relevant to local needs, aligned with 
BP’s business and undertaken in partnership with local organizations.
The programmes we support fall into three broad categories: 

building business skills and developing enterprise, supporting education 
and other community needs and sharing technical expertise with local 
governments. In some developing economies we also support community 
infrastructure programmes that help people improve their access to basic 

72    BP Annual Report and Form 20-F 2011

Business reviewresources such as drinking water and public health improvements. We 
work with local authorities, community groups and specialists to deliver 
these community programmes.

We use our technical knowledge and global reach where relevant to 

support national and regional governments in their efforts to develop their 
economies sustainably and provide public resources such as education 
and health. As well as country-specific projects, we support more general 
initiatives, including the Oxford Centre for the Analysis of Resource-Rich 
Economies, which studies how countries that are rich in natural resources 
such as oil and gas can use their resources for successful development 
rather than falling prey to mismanagement, corruption or other pitfalls.
Our direct spending on community programmes in 2011 was 

$103.7 million, which included contributions of $37.5 million in the US, 
$27.0 million in the UK (including $7.2 million to UK charities, of which 
$2.5 million for arts and culture, $2.8 million for enterprise development, 
$1.6 million for education), $2.6 million in other European countries and 
$36.6 million in the rest of the world. These reported amounts exclude 
social bonuses paid by BP to governments as part of licence acquisition 
costs and which have been capitalised as intangible assets on the group 
balance sheet. In such cases the group has no direct oversight of the 
expenditure. Contributions relating to economic recovery following the 
Deepwater Horizon oil spill are also excluded, see page 77 for details of 
these contributions.

To be sustainable as a business, BP needs employees who have the 
right skills for their roles and who understand the values and expected 
behaviours that guide everything we do as a group.

We have reviewed the way we express BP’s values and required 

behaviours with the goal of ensuring they support our aspirations for 
the future, align explicitly with our code of conduct and translate into 
responsible actions in the work we do every day. We conducted a 
programme in 2011 to renew employee awareness of our values and the 
behaviours as we work to reset our priorities as a company. See bp.com/
values for more information.

We had approximately 83,400 employees at 31 December 2011, 

compared with approximately 79,700 a year ago. During 2011, our 
headcount has been most significantly affected by both external hiring in 
order to build capability and acquisition and divestment activity as part of 
the strategy to re-shape the business.

The group people committee, chaired by the group chief executive, 

continues to take overall responsibility for key policy decisions relating to 
employees. In 2011, some of the key subjects discussed were longer-term 
people priorities; the design and implementation of a new reward model; 

our ambition on diversity and inclusion and a review of the governance of 
our learning programmes.

Our priorities for managing our people focus on ensuring the safety 
of our employees, strengthening capability, developing the potential of our 
own people, increasing diversity and inclusion and retaining the best people 
by motivating and engaging them.

Strengthening capability
The increasing demand for energy products and the complexity of our 
projects means that attracting and retaining skilled and talented people is 
vital to BP’s delivery of its strategy and plans.

In support of this, the group chief executive and each member 

of the executive team hold regular review meetings to ensure that 
appropriate plans to build capability are in place and that a rigorous and 
consistent succession process is followed for all group leadership roles.

To supplement our existing internal capability, we also target 
experienced and skilled professionals in the external market and are 
continuing to increase our intake of graduates to create a strong internal 
talent pipeline for the future.

We conduct external assessments for all new hires into BP at 

senior levels and for internal promotions to senior level and group leader 
level roles. These assessments ensure rigour and objectivity in our 
hiring and talent processes. They give an in-depth analysis of leadership 
behaviours, intellectual capacity and the required experience and skills for 
the role in question.

Our ongoing three-year graduate development programme 
continued in 2011. It currently has about 1,600 participants from all over 
the world.

Developing our people
We provide development opportunities for all our employees, including 
external and on-the-job training, international assignments, mentoring, 
team development days, workshops, seminars and online learning. We 
encourage all employees to take at least five training days per year.

We continue to work to embed appropriate leadership behaviours 

throughout our organization. In 2011, we delivered a new group leader 
development programme, designed to help our most senior leaders apply 
BP’s required leadership behaviours in their work. The first phase of the 
programme has now been completed with about half the group leader 
population having undertaken eight days of intensive training. We are 
refreshing the content and will start the next phase in 2012.

Our group-wide suite of management development programmes, 

Managing Essentials, has now run in 41 countries, with around 32,400 
participants.

Meeting the expectations of our people
We have reviewed our reward strategy, including how the group 
incentivizes business performance, with the aim of encouraging excellence 
in safety, compliance and operational risk management. Our revised 
performance management framework was implemented in 2011.

We encourage employee share ownership. For example, through 

the ShareMatch plan run in around 50 countries, we match BP shares 
purchased by our employees.

We aim to treat employees affected by mergers, acquisitions 

and joint ventures fairly and with respect, through open and regular 
communication. As part of the divestment programme following the Gulf 
of Mexico oil spill, BP has been seeking the same or comparable pay and 
benefits for employees transferring to other companies.

Diversity and inclusion
We are a global company and aim for a workforce that is representative of 
the societies in which we operate. We work to attract, motivate, develop 
and retain the best talent from the diversity the world offers – our ability 
to be competitive and to thrive globally depends on it. We believe success 
comes from the energy of our people.

Through living our values of safety, respect, excellence, courage 

and one team, we create an inclusive working environment where 
everyone can make a difference and give their best. Our work on diversity 
and inclusion is overseen by the group people committee who review 

BP Annual Report and Form 20-F 2011    73

Business review:  BP in more depthBusiness reviewperformance on a quarterly basis. They agree strategic direction and group 
standards which are then implemented through business specific diversity 
and inclusion plans. We supported the UK government-commissioned 
Lord Davies review in 2011, which made recommendations on increasing 
gender diversity on the boards of listed companies.

We are also incorporating detailed diversity and inclusion analysis 

into talent reviews, with processes to identify actions where any issues are 
found. We continue to increase the number of local leaders and employees 
in our operations so that they reflect the communities in which we operate.
By 2020, more than half our operations are expected to be in 

non-OECD countries and we see this as an opportunity to develop a new 
generation of experts and skilled employees. At the end of 2011, 15% of 
our group leaders were female and 19% came from countries other than 
the UK and the US. When we started tracking the composition of our group 
leadership in 2000, these percentages were 9% and 14% respectively. BP 
has increased the percentage of female leaders in 2011 and remains focused 
on building a more sustainable pipeline of diverse talent for the future.

We aim to ensure equal opportunity in recruitment, career 
development, promotion, training and reward for all employees, including 
those with disabilities. Where existing employees become disabled, our 
policy is to provide continuing employment and training wherever practicable.

Employee engagement
Executive team members hold regular town halls and webcasts to 
communicate with our employees around the world.

Team meetings and one-to-one meetings are the core of our 
employee engagement, complemented by formal processes through 
works councils in parts of Europe. These communications, along with 
training programmes, are designed to contribute to employee development 
and motivation by raising awareness of financial, economic, ethical, social 
and environmental factors affecting our performance. The group seeks to 
maintain constructive relationships with labour unions.

We conduct an employee engagement survey to monitor employee 

attitudes and identify areas for improvement. Our 2010 employee survey 
was delayed to allow for organizational changes to be reflected in the 
survey construction. This was completed and we carried out an employee 
engagement survey in 2011. The 2011 survey found that employees are 
committed and understand BP procedures and standards. The results 
show that there are a number of areas that can be improved. These include 
increasing transparency of the promotion process and being clear about the 
organization’s priorities. Business leadership teams reviewed the results of 
the survey and have agreed actions to address the identified issues.

The survey includes 10 questions which make up the employee 

satisfaction index. The overall employee satisfaction index score for 2011 
(62%) was below the score from 2009 (65%) but above that of 2008 (59%).

The code of conduct
The BP code of conduct sets the standard that all BP employees are 
required to work to. It is aligned with our values, group standards and legal 
requirements, and it clarifies the ethics and compliance expectations for 
everyone who works at BP. The code was updated in 2011 and now puts 
greater emphasis on a values-based approach.

The code defines what BP expects of its people in key areas such as 

safety, workplace behaviour, bribery and corruption and financial integrity.

Employees, contractors or other third parties who have questions or 

concerns that laws, regulations or the code of conduct may be breached, 
can get help through OpenTalk, an independent confidential helpline. The 
number of cases raised through OpenTalk in 2011 was 796, compared 
with 742 in 2010. In the US, former district court Judge Stanley Sporkin 
acts as an ombudsperson. Employees and contractors can contact him 
confidentially to report any suspected breach of compliance, ethics or the 
code of conduct, including safety concerns.

We take steps to identify and correct areas of non-compliance and 

take disciplinary action where appropriate. In 2011, 529 dismissals were 
reported by BP’s businesses for non-adherence to the code of conduct or 
unethical behaviour compared to 552 in 2010.

BP continues to apply a policy that the group will not participate 

directly in party political activity or make any political contributions, whether 
in cash or in kind. We review employees’ rights to political activity in each 

74    BP Annual Report and Form 20-F 2011

country where we operate. For example, in the US, BP facilitates staff 
participation in the political process by providing staff support to ensure BP 
employee political action committee contributions are publicly disclosed 
and comply with the law.

Technology

Technology in BP
We define technology in BP as the practical application of science to 
manage risks, capture business value and inform strategy development. 
This includes the research, development, demonstration and acquisition of 
new technical capabilities and support for the deployment of BP’s know-
how.

BP’s model continues to be one of selective technology leadership, 
under which we focus on major technology programmes that best support 
our business priorities and competitive performance.

External assurance is achieved through the technology advisory 

council, which advises the board and executive management on the state 
of technology within BP. The council is comprised of eminent business and 
academic technology leaders.

In 2011 we invested $636 million (of which $12 million related 

to the response to the Deepwater Horizon incident) in research and 
development (R&D). This compares with $780 million in 2010 (of which 
$211 million related to the response to the Deepwater Horizon incident), 
and $587 million in 2009. The increase in the underlying R&D spend is 
related to our major technology programmes. See Financial statements – 
Note 13 on page 208.

Our innovation ecosystem
BP has hundreds of scientists and technologists across the group, with 
seven major technology centres in the US, UK and Germany. We access 
external expertise through various forms of partnership and collaboration, 
from joint research agreements to venturing. We have a strategic approach 
to university relationships across our portfolio for the purposes of research, 
recruitment, policy insights and education.

BP has long-term research programmes with major universities and 
research institutions around the world, exploring areas from reservoir fluid 
flow to energy biosciences. These include the following programmes:
•	 The Energy Biosciences Institute (EBI) is BP’s largest external R&D 
investment, being a $500-million 10-year commitment to a multi-
disciplinary research partnership with the University of California 
Berkeley, the Lawrence Berkeley National Laboratory, and the University 
of Illinois. Now in its fourth year, the EBI is generating multiple 
innovations, particularly in the field of cellulosic conversion, that give our 
biofuels business viable opportunities for commercial application.

•	 BP’s energy sustainability challenge (ESC) is a research programme with 
13 leading universities to establish trusted peer-reviewed data on the 
relationships between natural resource usage and different energy 
pathways. The aim is to better understand the implications of energy 
production and consumption on potentially-constrained land, water and 
materials resources, and assess corresponding technology and policy 
opportunities. One of the early publications resulting from this research 
is the University of Augsburg’s handbook, Materials critical to the energy 
industry.

•	 In September 2011, BP opened the BP energy innovation laboratory at 
the Dalian Institute for Chemical Physics (DICP) in China as part of a  
10-year extension to our research agreements with DICP.

•	 In January 2011, BP started a new three-year policy programme at 

Harvard University’s Kennedy School focused on examining current and 
future potential policies on energy, security and climate change.

BP is a founding member of the UK’s Energy Technologies Institute 
(ETI) – a public/private partnership established in 2008 to accelerate low-
carbon technology development. As at 31 December 2011, the ETI has 
commissioned over $200 million of work covering over 30 projects across 
a wide range of technologies. The ETI has also developed an integrated 
model of the UK energy system which projects potential pathways out to 
2050 to meet the UK’s emissions targets.

Business reviewExploration and Production
In the upstream, our technology investment directly supports business 
strategy by focusing on safety and operational risk management; 
operational efficiency; increased recovery and reserves; and winning 
new access. Our strengths in exploration, deepwater, giant fields and 
gas are underpinned by flagship technology programmes that conduct 
scientific research in proprietary laboratories and in partnership with 
world-class research institutes and universities, to develop industry-leading 
technologies in imaging, facilities, well design and completions, and field 
recovery. These technologies are applied in the field, often in combination 
with real-time data acquisition and visualization, to drive risk reduction and 
excellence in exploration, developments and production.
•	 We are applying many of the lessons learned from the Deepwater Horizon 
incident and response throughout our global deepwater operations. The 
response required rapid innovation of new technologies to cap the well and 
contain the spill and – in partnership with industry partners, government 
agencies and leading universities – we have continued to develop and 
deploy new equipment and standards. Among many new developments in 
BP, we have built a global deepwater well cap and tooling package, now 
available for global deployment. This new capability includes a containment 
cap, remote operating vehicle (ROV) intervention system, subsea 
dispersant injection system, subsea debris removal equipment, and other 
tools.

•	 BP continues to develop and apply innovative exploration technologies. 

BP has applied two novel seismic acquisition methods developed 
in-house. Our distance separated simultaneous sources (DS3) and 
independent simultaneous sources (ISS®) methods were used to 
complete ultra-large, high density land seismic surveys in the Middle 
East and North Africa. BP also has field trials under way to extend these 
acquisition methods to the offshore.

•	 Through our Field of the Future® flagship technology programme, BP has 

deployed a range of digital, sensing and control technologies in its 
operations and is using the data to enhance real-time operating efficiency 
and recovery. Field of the Future tools are enabling more effective 
monitoring of production, multiple well components, and well 
characteristics such as temperature, which help to optimize hydrocarbon 
production. In addition, improved monitoring of facilities is helping to 
reduce risk, reducing downtime and saving tens of millions of dollars.
•	 In 2011, we successfully completed BP well advisor module field trials in 

Azerbaijan, a technology designed to aid decision making, enhance 
safety, reduce cost and bring wells on line more quickly. Through well 
advisor, we can harness real-time drilling data from sensors that see 
ahead of the drill, enabling us to deploy technologies such as early kick 
detection, which allow adjustments that can minimize down time during 
this critical phase of development. Rolling field trials will continue 
throughout 2012 to accelerate deployment.

•	 Enhanced oil recovery (EOR) technologies continue to push recovery 

factors to new limits. We believe that by increasing the overall recovery 
factor from our fields by 1%, we could be able to add 2 billion boe to our 
estimated ultimate recovery from existing fields. As at the end of 2011, 
BP, using its Designer Water® EOR technology, has treated 78 wells 
with Bright Water™ particles (a BP idea) in Alaska, Argentina, Azerbaijan, 
Pakistan and Russia. These applications have delivered more than 20 
million barrels of additional gross recoverable volumes at a development 
cost of less than $6 per barrel, and with an 80% success rate: BP has 
pumped almost 90% of all Bright Water treatments in the industry. 
Bright Water treatments involve the design and deployment of this 
sweep-improving component with regular injection water over a period 
of several days. These particles are activated deep in the reservoir to 
form a waterflood sweep improving diversion at a point between the 
injection and production wells.

•	 The $7.6 billion Clair Ridge project in the UK North Sea will be the first 
offshore project to use BP’s LoSal® EOR technology to increase the 
recovery of oil by modifying the salinity of the water injected into the 
reservoir. (LoSal EOR is part of BP’s suite of Designer Water 
technologies.) Earlier in 2011, BP and its partners also announced plans 
for the $5 billion redevelopment of the Schiehallion and Loyal fields, 

ISS®, Field of the Future®, Designer Water® and LoSal® are all trademarks of BP p.l.c.
Bright WaterTM is a trademark of Nalco Energy Services LP.

west of Shetland. The floating production, storage and offloading unit 
(FPSO) is to be built with full polymer EOR application capability.

Refining and Marketing
Our Refining and Marketing technology focus is both operational and 
customer facing. In our refineries and petrochemicals assets, we develop 
and apply technology to monitor operational integrity, to optimize product 
yields as a function of feedstock changes, to ensure quality attainment, and 
to improve energy efficiency. We also apply our expertise to create quality 
brand fuel and lubricant products for customers in on-road, off-road, air, sea 
and industrial applications globally.

For example:
•	 We continued to expand our integrity monitoring systems, with the 

deployment of over 1,000 wireless Permasense sensors in 2011, now 
spanning all of our BP-operated refineries worldwide. These wireless 
corrosion sensors are the product of collaborative research and 
development between BP and Imperial College London. The sensors 
enable frequent, repeatable wall-thickness monitoring and provide 
previously unavailable insights into the condition of oil and gas assets.
•	 In fuels and lubricants, our technology focus is on creating sustainable, 

differentiated and competitive products that enable advances in transport 
and industry. We continue to support our partners and customers in 
delivering greater energy efficiency and reduced CO2 emissions in both 
established and emerging markets. In 2011, BP developed a new range 
of industrial metalworking fluids that are both safer for workers and less 
harmful to the environment, a new gear lubricant for maximizing the 
efficiency of wind turbines, and co-engineered passenger car lubricants 
for optimizing engine fuel efficiency. We are also working on new fuels 
and lubricants that deliver improved fuel economy and compatibility with 
the latest engine technology and with biofuel components. In 2011, we 
launched our latest generation BP Ultimate gasoline and diesel fuels, and 
BP’s first differentiated-performance heavy duty diesel offer.

•	 In July, we opened a new industrial technology centre in Turin, Italy. It 

will serve customers across Europe and analyse about 30,000 oil 
samples a year.

•	 In petrochemicals, our proprietary processing technologies and 

operational experience continue to reduce the manufacturing costs and 
environmental impact of our plants, helping to maintain competitive 
advantage in purified terephthalic acid (PTA), paraxylene and acetic acid. 
A third PTA plant is currently being engineered for Zhuhai, China. With a 
capacity of 1.25 million tonnes per year it will be the first to employ BP’s 
latest PTA technology, enabling scale and cost efficiencies which 
significantly reduce both capital and conversion costs to a lower level 
than any other PTA technology.

•	 In the field of unconventional feedstocks, we collaborate with KBR to 

promote, market, and license the slurry-bed residue and coal-upgrading 
Veba combi-cracking (VCC) technology. VCC is a hydrogen-addition 
technology suitable for processing crude oil residuum into high-quality 
distillates or synthetic crude oil in the refining, upstream-field upgrading 
and coal-to-liquids sectors.

Business review:  BP in more depthBusiness reviewAlternative Energy
In Alternative Energy, we are aligning technology capability with future 
growth platforms, particularly biofuels.
•	 In addition to our expanding biofuel production business in Brazil, we are 

developing advanced technologies that will unlock the commercial 
potential of next generation biofuels. At our technology centre in San 
Diego, bioscientists are advancing the technology to commercialize 
cellulosic biofuels and utilizing our large scale demonstration facility in 
Louisiana to prove the scale-up of proprietary cellulosic technology. In 
the UK, BP and its partners have constructed a demonstration plant to 
accelerate commercial-scale production of biobutanol, a highly-efficient 
fuel molecule.

•	 Our portfolio of strategic venturing investments aims at putting BP at the 
forefront in terms of innovation, particularly in developing sustainable 
energy solutions. Our emerging business and ventures unit brings 
together BP’s venturing and carbon markets expertise with extensive 
carbon capture and storage capability and through this unit, we have 
more than 29 separate investments spanning three broad areas: 
bioenergy, electrification and carbon solutions.

The investments create insights and develop options to 

grow value for BP, for both its oil and gas assets as well as its low-
carbon businesses. They cover a range of specialized innovations and 
technologies, such as waste-heat recovery, energy storage, carbon 
funds and land-carbon projects, new solar and bio-energy technologies. 
For example, we have an investment stake in GMZ Energy, based 
in the US, which is commercializing materials that allow the efficient 
conversion of heat to electricity with a thermoelectric device – a building 
block for a new generation of energy-efficient products. The investment 
gives us insights into the ability of thermoelectric technology to recover 
low-grade waste heat sources cost-effectively across the group.

Gulf of Mexico oil spill

From response to restoration – summary
Building on the efforts of 2010, BP has continued to demonstrate 
its commitment to the US federal, state and local governments and 
communities of the Gulf Coast following the Deepwater Horizon oil spill. 
BP’s efforts in 2011 included:
•	 Continuing the clean-up of the waters and shorelines impacted across 

the Gulf of Mexico and the ongoing protection of fish and wildlife.
•	 Supporting the economic restoration of impacted sectors of the Gulf 
Coast economy through targeted support to the tourism and seafood 
industries.

•	 Continuing the funding of the $20-billion Deepwater Horizon Oil Spill 

Trust for the purposes of paying all legitimate individual, business, state 
and local government claims and funding of settlements and Natural 
Resource Damages (NRD) assessment and restoration activities.

•	 Progressing the NRD activities in collaboration with the federal and state 
trustee agencies and progressing both emergency and early restoration 
activities, including our voluntary commitment of up to $1 billion in early 
restoration projects.

•	 Continuing the support of independent long-term research through the 

Gulf of Mexico Research Initiative (GoMRI) to improve knowledge of the 
Gulf ecosystem and to better understand and mitigate the potential 
impacts of oil spills in the region and elsewhere.

Proposed settlement with the Plaintiffs’ Steering Committee
On 3 March 2012, BP announced that it had reached a settlement with the 
Plaintiffs’ Steering Committee (PSC), subject to final written agreement 
and court approvals, to resolve the substantial majority of legitimate 
economic loss and medical claims stemming from the Deepwater Horizon 
accident and oil spill. The PSC acts on behalf of individual and business 
plaintiffs in the Multi-District Litigation proceedings pending in New 
Orleans (MDL 2179).

The proposed settlement is comprised of two separate 

agreements, one to resolve economic loss claims and another to resolve 
medical claims. Each proposed agreement provides that class members 
would be compensated for their claims on a claims-made basis, according 
to agreed compensation protocols in separate court-supervised claims 
processes. The proposed agreement to resolve economic loss claims 
includes a BP commitment of $2.3 billion to help resolve economic loss 
claims related to the Gulf seafood industry and a fund to support continued 
advertising that promotes Gulf Coast tourism.

BP estimates that the cost of the proposed settlement, expected to 
be paid from the $20 billion Trust, would be approximately $7.8 billion. This 
includes the financial commitment for the Gulf seafood industry. 

The proposed economic loss settlement provides for a transition 

from the Gulf Coast Claims Facility (GCCF). A court-supervised transitional 
claims process for economic loss claims will be in operation while the 
infrastructure for the new settlement claims process is put in place. During 
this transitional period, the processing of claims that have been submitted 
to the GCCF will continue, and new claimants may submit their claims. BP 
has agreed not to wait for final approval of the economic loss settlement 
before claims are paid. The economic loss claims process will continue 
under court supervision before final approval of the settlement, first under 
the transitional claims process, and then through the settlement claims 
process established by the proposed economic loss agreement.

This proposed settlement does not include claims against BP made 

by the United States Department of Justice or other federal agencies 
(including under the Clean Water Act and for Natural Resource Damages 
under the Oil Pollution Act) or by the states and local governments. The 
proposed settlement also excludes certain other claims against BP, such as 
securities and shareholder claims pending in MDL 2185, and claims based 
solely on the deepwater drilling moratorium and/or the related permitting 
process.

160-164.

76    BP Annual Report and Form 20-F 2011

Business reviewCompleting the response
Throughout 2011, BP, working under the direction of the US Coast Guard’s 
Federal On-Scene Coordinator (FOSC), and collaboratively with individual 
federal and state entities, continued to complete the Deepwater Horizon 
operational response activities as described below.

Source control and site remediation
During the first half of 2011, BP completed the decommissioning of all 
source control equipment including all vessels used in the response. We 
also completed plugging and abandonment (P&A) of the second relief well 
and conducted a seabed survey. BP conducted a further site survey of 
the Macondo wellhead and the two relief wells during the third quarter of 
2011. Following these surveys it was determined that no further activity is 
necessary at the well site.

During the year we continued our efforts to recover and recycle 

waste material in order to minimize impacts. We also continued or 
completed the site remediation of multiple locations that were used during 
the response.

Residual clean-up in the Gulf of Mexico
Since the beginning of the Deepwater Horizon response multi-party 
Shoreline Clean-up Assessment Technique (SCAT) teams have 
continuously and systematically surveyed the shoreline to assess oiling 
conditions and develop shoreline treatment recommendations (STRs), 
which are implemented at the direction of the FOSC. Over 110,000 miles 
of aerial reconnaissance flights were conducted across the 11,000 miles of 
Gulf Coast shoreline. From this surveillance information, the SCAT teams 
identified more than 4,300 miles for further, ground-based survey. Of the 
Gulf Coast shoreline, 635 miles required some measure of mechanical or 
manual cleaning.

During 2011, mechanical or manual cleaning of the majority of 

the segments was completed. Patrolling and maintenance activities 
were initiated and will continue until the shoreline segments meet the 
applicable clean-up standards for the FOSC to determine that operational 
removal activity is complete. In November 2011, the FOSC also approved 
the Shoreline Clean-up Completion plan. This plan describes the process 
whereby the various shoreline segments included in the area of response 
operations can be surveyed, verified as meeting the applicable clean-up 
standards, and moved out of operational activity. It is expected that the 
majority of the 4,300 miles of the Gulf Coast shoreline within the area of 
response will be deemed operationally complete within 2012.

Environmentally sensitive areas were often hand cleaned. In some 

areas cleaning was paused at the direction of, or in consultation with, 
wildlife scientists, to minimize interference with migration patterns or 
breeding cycles.

The Coast Guard has indicated that if oil is discovered in a segment 
that has been deemed operationally complete, the Coast Guard will follow 
long-standing response protocols established under the law and contact 
whoever it believes is the responsible party or parties.

Response efforts guided by science
At the direction of the FOSC, scientific studies were conducted to study 
the status of oil and dispersants in the water and sediments of the Gulf. 
These studies are being used to guide continuing response activities in the 
near shore environment and to better understand the potential impacts 
of residual oil. These results have been published in Operational Scientific 
Advisory Team (OSAT) reports (OSAT-1 and OSAT-2 reports, and a toxicity 
addendum) and Net Environmental Benefits Analysis reports (NEBAs).

These reports confirmed the appropriateness of the steps taken to 
remove oil and mitigate the impact on the environment. The OSAT-2 report 
determined that further efforts, beyond guidelines established by the 
FOSC to remove the residual oil from the shoreline, could potentially pose 
a greater risk to the environment than allowing the residual oil to degrade 
naturally.

To assess the potential impacts on fauna, the FOSC directed the 
OSAT scientists to conduct a comprehensive toxicity study. The report, 
which was an addendum to the OSAT-1 report, was issued on 8 July 2011. 
Of the approximately 3,500 toxicity tests conducted, 90% showed no 
statistically significant effects on wildlife.

At the request of the FOSC, several NEBA studies and specialized activities 
were carried out, including an effort to detect anchors that had been 
deployed during the response to keep containment boom in place. Based 
on the NEBA results, the NEBA team recommended that the FOSC let 
the anchors remain in place to allow them to degrade through natural 
processes.

Economic restoration
BP continued to support economic recovery in local communities through a 
variety of actions and programmes in 2011.

Deepwater Horizon Trust activity
BP has established the Deepwater Horizon Oil Spill Trust (the Trust) in the 
amount of $20 billion to be used in compensating individuals, businesses, 
government entities and others who have been impacted by the oil spill. 
The Trust provides funds to satisfy legitimate state and local government 
claims resolved by BP, final judgments and settlements, legitimate state 
and local response costs, natural resource damages and related costs, 
and legitimate individual and business claims administered by the GCCF, 
which has been managed by Kenneth Feinberg. The proposed economic 
loss settlement announced on 3 March 2012 with the Plaintiffs’ Steering 
Committee on MDL 2179 provides for a transition from the GCCF. A court-
supervised transitional claims process for economic loss claims will be in 
operation while the infrastructure for the new settlement claims process 
is put in place. During this transitional period, the processing of claims that 
have been submitted to the GCCF will continue and new claimants may 
submit their claims. The establishment of the Trust does not represent 
a cap or floor on BP’s liabilities and BP does not admit to a liability of 
this amount.

In 2011, $1 billion was voluntarily set aside in the Trust for NRD 

early restoration projects. BP is working with federal and state trustees to 
select appropriate projects that will enhance habitats, wildlife and access 
for recreational use.

As at 31 December 2011, BP’s cumulative contributions to the 

Trust amounted to $15.1 billion since its inception, including our second-
year commitment of $5 billion and a total of $5.1 billion cash settlements 
received during 2011 from MOEX USA Corporation (MOEX), Weatherford 
US., L.P. (Weatherford), and Anadarko Petroleum Corporation (Anadarko). 
The remaining committed contributions as at 31 December 2011 totalling 
$4.9 billion are scheduled to be made by the end of 2012. In January 
2012, we contributed to the Trust the $250 million settlement received 
from Cameron International Corporation (Cameron). The Trust disbursed 
$3.7 billion in 2011 and the total paid out since its establishment amounted 
to $6.7 billion by the end of 2011.

Claims payments
All payments that were made in 2011 for legitimate claims by individuals, 
businesses and government entities were paid from the Trust. During the 
year, individuals and businesses received $3.1 billion in payments through 
the GCCF. More than 189,000 individual and business claimants accepted 
full and final settlements, while about 33,000 received interim payments. 
Since May 2010, more than $6.2 billion has been paid to individuals and 
businesses through the claims process, with the Trust paying $5.8 billion of 
this and BP paying the remainder prior to the establishment of the Trust.

Government entities received more than $40 million in claims 
payments during 2011. Nearly 60 loss-of-revenue claims have been paid to 
government entities since May 2010. By the end of 2011, BP had resolved 
over 90% of government claims filed.

During 2011, BP paid a total of $7.7 million to vessel owners whose 

vessels were involved in clean-up and protection activities as part of the 
Vessels of Opportunity (VoO) programme. In an effort to ensure fairness, 
BP instructed the external adjusters to broaden the original compensation 
guidelines. Once the new guidelines were established, adjusters have and 
are continuing to re-examine property damage claims from about 1,200 
vessel owners, whose property-damage claims had previously been denied 
or partially paid to ensure that property damages reported by claimants 
have been adequately addressed.

BP Annual Report and Form 20-F 2011    77

Business review:  BP in more depthBusiness reviewPromoting tourism along the Gulf Coast
To support economic restoration in the impacted Gulf Coast communities, 
BP entered into three-year agreements with the states of Alabama, Florida, 
Louisiana and Mississippi to promote tourism, monitor seafood safety and 
promote Gulf seafood.

During 2011, BP made commitments of $92 million in total over 

three years to support tourism promotion within the four affected states. 
This is in addition to $87 million in tourism grants provided by BP in 
2010. Each state is using its tourism funds to develop specific marketing 
programmes.

The proposed settlement announced on 3 March 2012 with the 
Plaintiffs’ Steering Committee in MDL 2179 includes a fund to support 
continued advertising that promotes Gulf Coast tourism.

Seafood testing, monitoring and promotion
Federal and state officials continue to collect and test seafood from the 
Gulf of Mexico, and the results of these tests have indicated that Gulf 
of Mexico seafood meets the US Food and Drug Administration (FDA) 
safety guidelines. The National Oceanic and Atmospheric Administration 
(NOAA) and the FDA are conducting widespread scientific evaluation of 
seafood samples to protect and reassure consumers. Since May 2010, 
more than 6,000 seafood samples have been collected by the FDA, NOAA, 
and state agencies in Louisiana, Mississippi, Alabama, and Florida. The 
FDA has also visited over 100 seafood processors and wholesalers across 
the Gulf Coast, collecting seafood samples and inspecting processing 
plants for biological, chemical, and physical hazards. Levels of residues of 
oil contamination in seafood have consistently tested between 100 and 
1,000 times lower than the safety thresholds established by the FDA.  
Test results from NOAA, the FDA, and the Gulf of Mexico states are 
publicly available.

Recreational fishing showed signs of recovery in 2011. To raise 

public awareness of Gulf of Mexico seafood, BP has committed $34 million 
for Gulf of Mexico states to conduct seafood testing and $48 million to 
market Gulf of Mexico seafood.

Rig Worker Assistance Fund
BP established a $100-million Rig Worker Assistance Fund through the 
Baton Rouge Area Foundation (the Foundation) to support unemployed rig 
workers experiencing economic hardship as a result of the moratorium on 
deepwater drilling imposed by the US federal government. In 2011, the 
Foundation awarded $5.8 million to an expanded pool of applicants, after 
awarding $5.6 million to nearly 350 rig workers in 2010. With less than 
2,000 applying for funds, the Foundation granted $18 million of the BP 
contribution to community-based organizations through its Future for the 
Gulf Fund. At the end of 2011, the Foundation was assessing additional 
funding requests from organizations assisting those impacted by the spill, 
and has said it hopes to complete the distribution of the BP contribution by 
the end of 2012.

Environmental restoration
We made progress during 2011 on multiple fronts as part of the  
ongoing efforts to assess and address injury to natural resources in the 
Gulf of Mexico.

We continued to support and participate in the Natural Resource 
Damages (NRD) process. Work has been completed or is under way on 
more than 150 cooperative studies with federal and state agencies to 
gather data on potential impacts and injuries to birds, turtles and mammals; 
fish and shell fish; near shore and shoreline habitats; and the Gulf of 
Mexico water column and sediment.

We also worked with the Natural Resource Damage Assessment 
(NRDA) trustees to begin assessing the potential lost human use of these 
Gulf Coast natural resources. Additional studies focused on the potential 
impacts on historical and archaeological resources and endangered species.

During the year we also supported two emergency restoration 

projects and made a major commitment to fund early restoration projects. 
In addition, the National Fish and Wildlife Foundation funded several 
projects during 2011 using funds provided by BP in 2010 from the sale of 
oil recovered from the spill.

We are working with NOAA to prepare and provide access to 

summaries of the studies completed and data gathered during the 

78    BP Annual Report and Form 20-F 2011

cooperative assessment process. We also prepared and participated in a 
variety of scientific publications and seminars as part of our efforts to share 
learnings from the oil spill as broadly as possible.

NRD process under way
In 2011, we continued to work with scientists and trustee agencies 
through the NRD process to identify natural resources that may have 
been exposed to oil or otherwise impacted by the incident, and to look for 
evidence of injury.

As part of the NRD process, trustees from each state and the 
federal government held a series of public meetings during 2011 in each of 
the five states affected by the Deepwater Horizon oil spill. These  
focused on the status of potential injury assessments and of potential 
restoration process. To date, BP has paid over $600 million for NRD 
assessment efforts.

Public comments were collected as part of the Programmatic 

Environmental Impact Statement (PEIS) process, which will inform one of 
the core planning documents for restoration. A final PEIS is scheduled to 
be released by the trustees in late 2012.

Emergency restoration projects
Emergency restoration projects are defined under the Oil Pollution Act of 
1990 (OPA 90) as preventative measures or actions undertaken to stop 
continuing injuries to resources and to mitigate potential effects of the 
spill. During 2011, two emergency restoration projects were completed 
along the Gulf Coast in support of birds and turtles. A third project is in the 
planning phase for submerged aquatic vegetation and is scheduled to be 
implemented in 2012.

Early restoration projects
Under an agreement signed with federal and state trustees in April 2011, 
BP voluntarily committed to provide up to $1 billion to fund projects that 
will accelerate restoration efforts in Gulf Coast areas that were impacted by 
the Deepwater Horizon oil spill.

The agreement enables work on restoration projects to begin at 

the earliest opportunity, before all of the studies under the NRDA process 
are complete, and before funding is required by OPA 90. Priority will be 
assigned to projects aimed at improving areas that offer the greatest 
benefits to wildlife, habitat, and recreational use that were impacted as a 
result of the incident.

In December 2011, state and federal trustees unveiled the first set 

of early environmental restoration projects that are proposed for funding 
under the agreement. The eight proposed projects are located in  
Alabama, Florida, Louisiana and Mississippi. Collectively, the projects will 
restore and enhance wildlife, habitats, the ecosystem services provided 
by those habitats, and provide additional access for fishing, boating and 
related recreational uses. More early restoration projects are anticipated in 
the future.

Funding for the early restoration projects will come from the 
$20-billion Trust. Additional information about the projects, projected costs 
and proposed credits can be found on the NOAA website.

Environmental studies and reports
BP is committed to sharing and providing access to the numerous studies 
and reports generated during the course of the response. In total, since 
May 2010, more than 150 NRDA studies have been completed or are in 
progress throughout the Gulf. As the studies are completed, summaries 
are expected to be published as appropriate either on BP’s website or on 
government websites. Our website also contains numerous  
technical reports and documentation on a variety of environmental and 
health-related topics.

National Fish and Wildlife Foundation projects
In 2010, BP donated $22 million from the net revenue of the sale of oil 
recovered from the spill to the US National Fish and Wildlife Foundation 
(NFWF) which used the funds to quickly implement several conservation 
projects along the Gulf Coast.

In 2011, the NFWF announced that it issued $6.9 million in 
grants from the Recovered Oil Fund for Wildlife for 22 new projects. The 

Business reviewBP considers that it is not possible to estimate reliably any obligation in 
relation to NRD claims under OPA 90 (other than the estimated costs of 
the assessment phase and the costs relating to emergency restoration 
and the $1 billion agreement for early restoration), any amounts in relation 
to fines and penalties except for those relating to the CWA and litigation 
arising from alleged violations of OPA 90. These items are therefore 
contingent liabilities.

BP holds a 100% interest in the Macondo well, with the lease 

interests previously held by MOEX and Anadarko now assigned to BP as 
part of the settlement agreements. MOEX paid BP $1.1 billion in cash and 
Anadarko paid BP $4 billion in cash to settle all outstanding claims between 
the companies related to the incident and to the prospect.

proceedings and investigations relating to the incident.

grants, which were supplemented by a further $3.3 million from other 
contributors, were awarded for projects designed to:
•	 Improve sea turtle hatchling success across 56 miles of priority Florida 

beaches.

•	 Increase the capacity of marine mammal and sea turtle treatment 

facilities.

•	 Restore a combined 3.5 miles of oyster reefs, which in turn protect 

sensitive coastal habitat.

•	 Reduce the incidence of sea turtles being caught in the course of 

recreational and commercial fishing.

Commitment to long-term oil spill research
In 2010, BP committed $500 million over 10 years to fund independent 
scientific research through the Gulf of Mexico Research Initiative (GoMRI). 
The research will improve knowledge of the Gulf ecosystem and help the 
industry and others to better understand and mitigate the impact of oil 
spills in the region and elsewhere.

In June 2011, the GoMRI Research Board awarded 17 grants 

totalling $1.5 million to support scientists as they continue time-sensitive 
data collection. In August 2011, the Research Board awarded a total of 
$112.5 million over three years to eight consortia comprised of over 70 
research institutions. All eight consortia are led by Gulf Coast institutions. 
Research recipients will use the grants to investigate the fate of oil 
released by the spill, and for the development of new tools and technology 
for responding to future spills and improving mitigation and restoration.

In December 2011, the GoMRI Research Board also issued a 
request for proposals (RFP) for approximately $7.5 million per year for three 
years, in smaller grants to individual or small teams of researchers.

Rebuilding trust through effective communications
During 2011, we worked to engage, inform and communicate with a wide 
range of stakeholders throughout the region. We supported community 
events and we shared information on a variety of issues and concerns with 
individuals, community organizations, business leaders, elected officials, 
non-governmental organizations and the news media.

Financial update
Profit before tax for the group includes a pre-tax credit of $3.8 billion 
and finance costs of $0.1 billion in relation to the Gulf of Mexico oil spill. 
The pre-tax credit reflects $5.5 billion in relation to settlements reached 
with MOEX, Weatherford, Anadarko and Cameron, partially offset by 
further costs associated with the ongoing spill response, adjustments to 
provisions, and an increase in the amount provided for legal fees, as well as 
functional expenses of BP’s Gulf Coast Restoration Organization (GCRO).

Provisions were established during 2010 for the environmental 

expenditure, spill response costs, litigation and claims, and Clean Water 
Act (CWA) penalties. Most of the costs incurred in 2011 were covered 
by these existing provisions. Pre-tax charges were recorded in 2011 
of $0.4 billion for the functional expenses of the GCRO, $1.1 billion for 
increases in the amounts provided, primarily related to spill response costs 
and legal fees, a $0.1 billion finance charge for unwinding of discount on 
provisions, and $0.1 billion for spill response costs charged directly to the 
income statement. These charges partially offset the $5.5 billion credit for 
settlements reached during the year.

As at 31 December 2011, the cumulative charges for provisions to 

be paid from the Trust and the associated reimbursement asset recognized 
amounted to $16.6 billion. This represented an increase of  
$4.0 billion in the provisioned amounts during 2011, primarily for the 
$2.1-billion expected impact of the proposed settlement announced on 
3 March 2012 with the Plaintiffs’ Steering Committee in MDL 2179, the 
$1-billion commitment to NRD early restoration and new provisions for 
personal injury and death claims and Vessel of Opportunity programme 
claims. A further $3.4 billion could be provided in subsequent periods for 
items covered by the Trust, with no net impact on the income statement.

BP has provided for all potential liabilities that can be estimated 
reliably at this time, including fines and penalties under the CWA. The 
total amounts that will ultimately be paid by BP in relation to all obligations 
relating to the incident are subject to significant uncertainty.

Business review:  BP in more depthBusiness reviewAdditionally, our activities include the marketing and trading of natural gas, 
power and natural gas liquids. These activities provide routes into liquid 
markets for BP’s produced gas, and generate margins and fees associated 
with the provision of physical products and derivatives to third parties and 
income from asset optimization and trading.

Our oil and natural gas production assets are located onshore and 

offshore and include wells, gathering centres, in-field flow lines, processing 
facilities, storage facilities, offshore platforms, export systems (e.g. transit 
lines), pipelines and LNG plant facilities.

Upstream operations in Abu Dhabi, Argentina, Bolivia, Chile, Russia, 

Venezuela and Vietnam as well as some of our operations in Angola, 
Canada, Indonesia and Trinidad are conducted through equity-accounted 
entities.

Our market
Energy demand, and in particular oil demand, has followed overall 
economic trends in recent years, recovering strongly in 2010 but facing 
more challenging conditions in 2011.

Dated Brent for the year averaged $111.26 per barrel, 40% 

above 2010’s average of $79.50 per barrel. In 2012, we expect oil price 
movements to continue to be driven by the pace of global economic 
growth and its resulting implications for oil consumption, and by OPEC 
production decisions.

Natural gas prices diverged globally in 2011, reflecting different 
regional dynamics. The average US Henry Hub First of Month Index fell 
to $4.04/mmBtu, an 8% decrease from 2010, while in Europe prices 
increased. Spot gas prices at the UK National Balancing Point increased by 
33% to an average of $56.33 pence per therm for 2011.

After a record increase in 2010, global gas consumption growth 

moderated in 2011. In the US, economic momentum supported gas use 
in the first half of the year and a hot summer raised demand. Yet domestic 
production outpaced consumption growth due to further increases in the 
availability of shale gas.

In 2012, we expect gas markets to continue to be driven by the 
economy, weather, domestic production, LNG supply and reductions in 
nuclear power generation following the Fukushima disaster in Japan in 
March 2011.

Our strategy
In Exploration and Production, our highest priority is to ensure safe, reliable 
and compliant operations worldwide. Our strategy is to invest to grow long-
term value by continuing to build a portfolio of material, enduring positions 
in the world’s key hydrocarbon basins with a focus on deepwater, gas 
value chains and giant fields. Our strategy is enabled by:
•	 A continued focus on safety and managing risk.
•	 Strong relationships built on mutual advantage, deep knowledge of the 

basins in which we operate, and technology.

•	 Building capability along the value chain in Exploration, Developments 

and Production.

•	 Actively managing our portfolio.

We intend to increase investment with a focus on Exploration, a key 
source of value creation, and evolve the nature of our relationships, 
particularly with national oil companies.

Exploration and Production

At the end of 2010, as part of our response to the Deepwater Horizon 
oil spill, we announced the decision to reorganize the Exploration and 
Production segment to create three separate divisions: Exploration, 
Developments and Production, integrated through a Strategy and 
Integration organization. This structure was established in March 2011 
and each of the four parts is led by an executive vice president reporting 
directly to the group chief executive. The new organization is designed 
to change the way we operate, with a particular focus on managing 
risk, delivering common standards and processes and building technical 
capability. The new organization has not changed the way we report our 
operating segments under IFRS.

The Exploration division is accountable for renewing our resource 

base through access, exploration and appraisal. The Developments 
division is accountable for the safe and compliant execution of wells 
(drilling and completions) and major projects and comprises the global 
wells organization and the global projects organization, which were 
established in 2011. The Production division is accountable for safe and 
compliant operations, including upstream production assets, midstream 
transportation and processing activities, and the development of our 
resource base. Divisional activities are integrated on a regional basis by a 
regional president reporting to the Production division. The Strategy and 
Integration organization is accountable for optimization and integration 
across the divisions, including the delivery of support from the group’s 
finance, procurement and supply chain, human resources, technology and 
information technology functions.

From 1 January 2012, the group’s investment in TNK-BP will 
be reported as a separate operating segment, rather than within the 
Exploration and Production segment, reflecting the way in which the 
investment is now managed.

The group safety and operational risk (S&OR) function maintains 

our global safety standards. S&OR staff are deployed at the operating level 
within the Exploration and Production segment to support the systematic 
and disciplined application of those standards. This creates an independent 
reporting line, working alongside line management while having the power 
to intervene.

Our Exploration and Production segment included upstream 

and midstream activities in 30 countries in 2011, including Angola, 
Azerbaijan, Brazil, Canada, Egypt, India, Iraq, Norway, Russia, Trinidad & 
Tobago (Trinidad), the UK, the US and other locations within Africa, Asia, 
Australasia and South America, as well as gas marketing and trading 
activities, primarily in Canada, Europe and the US. Upstream activities 
involve oil and natural gas exploration, field development and production. 
Our exploration and appraisal programme is currently focused on Angola, 
Australia, Azerbaijan, Brazil, Canada, Egypt, the deepwater Gulf of Mexico, 
the UK North Sea, Oman and onshore US. Major development areas 
include Angola, Australia, Azerbaijan, Canada, Egypt, the deepwater Gulf of 
Mexico, North Africa, and the UK North Sea. During 2011, production came 
from 24 countries. The principal areas of production are Angola, Argentina, 
Azerbaijan, Egypt, Russia, Trinidad, the UAE, the UK and the US.

Midstream activities involve the ownership and management 
of crude oil and natural gas pipelines, processing facilities and export 
terminals, LNG processing facilities and transportation, and our NGL 
extraction businesses in Canada, Indonesia, the US and the UK. Our most 
significant midstream pipeline interests are the Trans-Alaska Pipeline 
System in the US; the Forties Pipeline System and the Central Area 
Transmission System pipeline, both in the UK sector of the North Sea; 
the South Caucasus Pipeline, which runs from Azerbaijan through Georgia 
to the Turkish border; and the Baku-Tbilisi-Ceyhan pipeline, which runs 
through Azerbaijan, Georgia and Turkey. Major LNG activities are located in 
Australia, Indonesia and Trinidad. BP is also investing in the LNG business 
in Angola.

2011 performance
Safety and operational risk
In Exploration and Production, ensuring safe, reliable and compliant 
operations remains our highest priority. The organizational and governance 
changes in Exploration and Production and S&OR have been designed to 
ensure we achieve this, supported by a systematic framework provided by 
BP’s operating management system (OMS). All Exploration and Production 
operated businesses, with the exception of those recently acquired, are 
now applying our OMS to govern their BP operations and have begun 
working to achieve conformance to standards and practices required by 
OMS through the performance improvement cycle process. We continue 
to work to enhance local systems and processes at all our sites. See Safety 
on pages 65-66 for more information on OMS.

Safety performance is monitored by a suite of input and output 

metrics which focus on personal and process safety including operational 
integrity, occupational health and all aspects of compliance.

In 2011, there were no workforce fatalities in Exploration and 

Production. In 2010, there was one workforce fatality.

The recordable injury frequency (RIF), which measures the number 
of recordable injuries to the BP workforce per 200,000 hours worked, was 
0.30. This is lower than 2010 when it was 0.32 and 2009 when it was 0.39. 
Our day away from work case frequency (DAFWCF) in 2011 was 0.060. 
This is lower than 2010 when it was 0.063 but higher than 2009 when it 
was 0.038.

In 2011, the number of reported loss of primary containment 

(LOPC) incidents in Exploration and Production was 152, down from 194 
in 2010. The number of reported oil spills equal to or larger than 1 barrel 
during 2011 was 71, down from 117 in 2010.

Financial and operating performance
We continually seek access to resources and in 2011, in addition to new 
access resulting from acquisitions as detailed on page 83, this included 
Angola, where BP gained access to five new deepwater exploration and 
production blocks covering 24,200km2; Australia, where BP was awarded 
four blocks covering 24,500km2 in the Ceduna Sub Basin off the coast of 
South Australia; Azerbaijan, where the republic of Azerbaijan ratified the 
Shafag-Asiman production-sharing agreement (PSA) covering 1,100km2 
in the Caspian Sea; China, where BP was awarded access to a 9,700km2 
block in the South China Sea; deepwater Gulf of Mexico, where 12 leases 
from the March 2010 Outer Continental Shelf Lease Sale 213 covering  
280km2 were executed; Indonesia, where BP was awarded four coalbed 
methane PSAs covering 4,800km2 in the Barito basin of South Kalimantan 
and two oil and gas PSAs covering 16,400km2 offshore in the Arafura Sea; 
and Trinidad, where BP was awarded two deepwater blocks covering 
3,600km2, subject to government approval.

In September 2011, we announced the Moccasin oil discovery in 

the deepwater Gulf of Mexico (not BP-operated). In October 2011, we 
announced the Salmon gas discovery in Egypt’s Nile Delta. In 2011, we 
took final investment decisions on three projects and two major projects 
came onstream: Serrette in Trinidad and Pazflor in Angola.

Production for 2011 was lower than last year. After adjusting for the 

effect of entitlement changes in our PSAs and the effect of acquisitions 
and disposals, underlying production was 7% lower than 2010. This 
primarily reflects lower Gulf of Mexico production as a result of the impact 
of the drilling moratorium as well as the impact of turnaround maintenance 
activities. In 2011, full-year production growth in TNK-BP was 2.8%.

Sales and other operating revenues for 2011 were $75 billion, 

compared with $66 billion in 2010 and $58 billion in 2009. The increase 

BP Annual Report and Form 20-F 2011    81

Business review: BP in more depthBusiness reviewin 2011, compared with 2010, primarily reflected higher oil and gas 
realizations, partly offset by lower production. The increase in 2010, 
compared with 2009, primarily reflected higher oil and gas realizations, 
partly offset by lower production.

The replacement cost profit before interest and tax for 2011 was 

$30,500 million, compared with $30,886 million for the previous year. 2011 
included net non-operating gains of $1,130 million, primarily a result of 
gains on disposals being partly offset by impairments, a charge associated 
with the termination of our agreement to sell our 60% interest in Pan 
American Energy LLC (PAE) to Bridas Corporation and other non-operating 
items. (See page 58 for further information on non-operating items.) In 
addition, fair value accounting effects had a favourable impact of $11 
million relative to management’s measure of performance. (See page 58 
for further information on fair value accounting effects.)

The primary additional factors contributing to the 1% decrease in 

replacement cost profit before interest and tax were higher realizations 
partially offset by lower production volumes (including in higher margin 
areas), rig standby costs in the Gulf of Mexico, higher costs related to 
turnarounds, certain one-off costs and higher exploration write-offs.

Total capital expenditure including acquisitions and asset exchanges 

in 2011 was $25.5 billion (2010 $17.8 billion and 2009 $14.9 billion). (See 
page 83 for further information on acquisitions.)

Development expenditure of subsidiaries incurred in 2011, 

excluding midstream activities, was $10.2 billion, compared with $9.7 
billion in 2010 and $10.4 billion in 2009.

Provisions for decommissioning increased from $10.5 billion at the 

end of 2010 to $17.2 billion at the end of 2011. The increase reflects higher 
cost estimates, which are in part driven by new requirements in the Gulf of 
Mexico. Decommissioning costs are initially capitalized within fixed assets 
and are subsequently depreciated as part of the asset.

Prior years’ comparative financial information
The replacement cost profit before interest and tax for the year ended 
31 December 2010 of $30,886 million included net non-operating gains of 
$3,199 million, comprised primarily of gains on disposals that completed 
during the year partly offset by impairment charges and fair value losses 
on embedded derivatives. In addition, fair value accounting effects had an 
unfavourable impact of $3 million relative to management’s measure of 
performance.

The replacement cost profit before interest and tax for the year 

ended 31 December 2009 of $24,800 million included a net credit for non-
operating items of $2,265 million, with the most significant items being 
gains on the sale of operations (primarily from the disposal of our 46% 
stake in LukArco, the sale of our 49.9% interest in Kazakhstan Pipeline 
Ventures LLC and the sale of BP West Java Limited in Indonesia) and fair 
value gains on embedded derivatives. In addition, fair value accounting 
effects had a favourable impact of $919 million relative to management’s 
measure of performance.

The primary additional factor contributing to the 25% increase in 

the replacement cost profit before interest and tax for the year ended 
31 December 2010 compared with the year ended 31 December 2009 were 
higher realizations, lower depreciation and higher earnings from equity-
accounted entities, partly offset by lower production, a significantly lower 
contribution from gas marketing and trading and higher production taxes.

Outlook
In 2012, we will continue to drive operational risk reduction through the 
new Exploration and Production segment structure, supported by the 
S&OR function. Our divisions will work to manage risk and deliver common 
standards, driving functional excellence across the lifecycle of exploration, 
development and production, while continuing to focus on building our 
technical capability for the future. We believe that our portfolio of assets 
remains well positioned to compete and grow value in a range of external 
conditions and we continue to increase both investment and operating cash. 
We expect production in 2012 to be broadly flat, normalizing for divestments 
and price effects, and excluding TNK-BP. This is the net effect of growth 
from new projects and new production from India and Brazil being offset by 
normal base decline. In 2012, we intend to drill 12 exploration wells, start 
up six major projects, and increase our activity in the Gulf of Mexico to eight 
operational rigs, subject to approvals by US regulators.

82    BP Annual Report and Form 20-F 2011

Upstream activities
Exploration
The group explores for oil and natural gas under a wide range of licensing, 
joint venture and other contractual agreements. We may do this alone 
or, more frequently, with partners. BP acts as operator for many of these 
ventures.

In 2011, our exploration and appraisal costs, excluding lease 

acquisitions, were $2,398 million, compared with $2,706 million in 2010 
and $2,805 million in 2009. These costs included exploration and appraisal 
drilling expenditures, which were capitalized within intangible fixed assets, 
and geological and geophysical exploration costs, which were charged to 
income as incurred. Approximately 76% of 2011 exploration and appraisal 
costs were directed towards appraisal activity. In 2011, we participated in 
308 gross (73.33 net) exploration and appraisal wells in nine countries. The 
principal areas of exploration and appraisal activity were Angola, Australia, 
Azerbaijan, Brazil, Canada, Egypt, the deepwater Gulf of Mexico, the UK 
North Sea, Oman and onshore US.

Total exploration expense in 2011 of $1,520 million (2010 $843 

million and 2009 $1,116 million) included the write-off of expenses related 
to unsuccessful drilling activities in the deepwater Gulf of Mexico ($284 
million), Asia Pacific ($61 million) and others ($5 million). It also included 
$14 million related to decommissioning of idle infrastructure, as required by 
the Bureau of Ocean Energy Management Regulation and Enforcement’s 
Notice of Lessees 2010 G05 issued in October 2010.

Reserves booking from new discoveries will depend on the results 
of ongoing technical and commercial evaluations, including appraisal drilling.

Proved reserves replacement
Total hydrocarbon proved reserves, on an oil equivalent basis including 
equity-accounted entities, comprised 17,748mmboe (11,426mmboe 
for subsidiaries and 6,322mmboe for equity-accounted entities) at 
31 December 2011, a decrease of 2% (decrease of 5% for subsidiaries 
and increase of 5% for equity-accounted entities) compared with the 
31 December 2010 reserves of 18,071mmboe (12,077mmboe for 
subsidiaries and 5,994mmboe for equity-accounted entities). Natural 
gas represented about 40% (55% for subsidiaries and 14% for equity-
accounted entities) of these reserves. The change includes a net decrease 
from acquisitions and disposals of 361mmboe (218mmboe net decrease 
for subsidiaries and 143mmboe net decrease for equity-accounted 
entities). Acquisitions occurred in Brazil, Canada, India, the UK, the US, 
Venezuela and Vietnam. Divestments occurred in Algeria, Azerbaijan, 
Canada, Colombia, Pakistan, Trinidad, the US, the UK, Venezuela and 
Vietnam.

The proved reserves replacement ratio is the extent to which 
production is replaced by proved reserves additions. This ratio is expressed 
in oil equivalent terms and includes changes resulting from revisions to 
previous estimates, improved recovery and extensions and discoveries. 
For 2011, the proved reserves replacement ratio excluding acquisitions and 
disposals was 103% (106% in 2010 and 129% in 2009) for subsidiaries 
and equity-accounted entities, 45% for subsidiaries alone and 194% for 
equity-accounted entities alone. The 2011 reserves additions for TNK-BP 
include the effect of moving from life-of-licence measurement to life-of-
field measurement, reflecting TNK-BP’s track record of successful licence 
renewal. Excluding this effect, our 2011 reserves replacement ratio 
excluding acquisitions and disposals would have been 83%.

In 2011, net additions to the group’s proved reserves (excluding 

production and sales and purchases of reserves-in-place) amounted to 
1,320mmboe (348mmboe for subsidiaries and 972mmboe for equity-
accounted entities), through revisions to previous estimates, improved 
recovery from, and extensions to, existing fields and discoveries of new 
fields. Of our subsidiary reserves additions through improved recovery 
from, and extensions to, existing fields and discoveries of new fields, 
approximately 26% were associated with new projects and were proved 
undeveloped reserves additions. The remaining additions were in existing 
developments where they represented a mixture of proved developed and 
proved undeveloped reserves. Volumes added in 2011 principally relied 
on the application of conventional technologies. The principal reserves 
additions in our subsidiaries were in the US (San Juan North, Mad Dog, 
Ursa, Prudhoe Bay, Hawkville), Trinidad (Cashima, Juniper) and Indonesia 
(Tangguh). The principal reserves additions in our equity-accounted entities 

Business reviewwere in Russia (Orenburg, Slavneft, Verkhnechonskoye, Uvat, Talinskoye), 
Venezuela (Petromonagas) and Argentina (Cerro Dragon).

Twelve per cent of our proved reserves are associated with PSAs. 

The countries in which we operated under PSAs in 2011 were Algeria, 
Angola, Azerbaijan, Egypt, India, Indonesia, Oman, Trinidad and Vietnam. 
In addition, the technical service contract (TSC) under which we operate in 
Iraq functions as a PSA.

Production
Our total hydrocarbon production during 2011 averaged 3,454 thousand 
barrels of oil equivalent per day (mboe/d). This comprised 2,094mboe/d for 
subsidiaries and 1,360mboe/d for equity-accounted entities, a decrease of 
16% (decreases of 19% for liquids and 13% for gas) and an increase of 
2% (increases of 2% for liquids and 5% for gas) respectively compared 
with 2010. In aggregate, after adjusting for entitlement impacts in our PSAs 
and the effect of acquisitions and disposals, production was 7% lower 
than 2010. For subsidiaries, 37% of our production was in the US, 20% in 
Trinidad and 8% in the UK.

The group and its equity-accounted entities have numerous long-
term sales commitments in their various business activities, all of which 
are expected to be sourced from supplies available to the group that 
are not subject to priorities, curtailments or other restrictions. No single 
contract or group of related contracts is material to the group.

Acquisitions and disposals
During 2011, we undertook a number of acquisitions and disposals. In 
total, disposal transactions generated $1.1 billion in proceeds during 
2011 including repayment of the $3.5 billion disposal deposit relating to 
Pan American Energy. See Financial statements – Note 5 on page 197. 
With regards to proved reserves, 211mmboe were acquired in 2011 
(approximately 94mmboe for subsidiaries and approximately 117mmboe 
for equity-accounted entities), while 572mmboe were disposed of 
(approximately 312mmboe for subsidiaries and approximately 260mmboe 
for equity-accounted entities).

Acquisitions
•	 On 24 January 2011, BP exercised a preferential right to acquire Shell’s 
working interest in the Marlin and Dorado producing fields in the Gulf 
of Mexico for a total consideration of $257 million. This brought BP’s 
working interest in both fields to 100%.

•	 On 12 May 2011, BP completed the purchase of 10 exploration 

and production blocks in Brazil from Devon Energy, concluding the 
agreement announced in 2010.

•	 On 30 August 2011, BP completed its acquisition from Reliance 

Industries Limited (RIL) of a 30% stake in 21 oil and gas PSAs that 
RIL operates in India for an aggregate consideration of $7.0 billion. In 
November 2011, the two companies formed a 50:50 joint venture for the 
sourcing and marketing of gas in India. See India for further information 
on page 87.

Disposals
•	 On 24 January 2011, following the approval of the Colombian authorities, 

BP completed the sale of its oil and gas exploration, production and 
transportation business in Colombia to a consortium of Ecopetrol, 
Colombia’s national oil company, and Talisman of Canada. The sale had 
been announced in August 2010.

•	 On 22 February 2011, BP announced its intention to sell its interests in 
a number of operated oil and gas fields in the UK including the Wytch 
Farm onshore oilfield in Dorset and all of BP’s operated gas fields in the 
southern North Sea, including associated pipeline infrastructure and the 
Dimlington terminal. The sale of Wytch Farm to Perenco UK Limited 
completed on 14 December 2011 for consideration of up to $610 million 
in cash, which includes $55 million contingent on Perenco’s future 
development of the Beacon field and on oil prices in 2011-2013. A sale 
of the southern North Sea assets has yet to be concluded. The assets 
do not yet meet the criteria to be reclassified as non-current assets held 
for sale and it is not yet possible to estimate the financial effect of the 
intended disposal of these assets.

•	 In April 2011, the Wattenberg Plant in Colorado was divested to 

Anadarko for $575 million.

•	 In April 2011, an exchange agreement was signed with Bluestone 

Natural Resources, LLC for the divestment of a mature gas field in South 
Texas in exchange for acreage in a non-operated property in Eagle Ford.

•	 In June 2011, BP completed the sale of its upstream businesses in 

Venezuela to TNK-BP.

•	 On 5 July 2011, BP sold half of the 3.29% interest in the Azeri-Chirag-

Gunashli development in the Caspian Sea which had been acquired from 
Devon Energy in 2010 to Azerbaijan (ACG) Limited, an affiliate wholly 
owned and controlled by the State Oil Company of the Republic of 
Azerbaijan (SOCAR) for $485 million.

•	 On 16 September 2011, the sale of BP’s upstream assets in Pakistan 

to United Energy Group (UEG) was completed. UEG has now assumed 
control of the upstream assets. The sale, for $775 million, had been 
announced at the end of 2010.

•	 In October 2011, BP completed the sale of Tuscaloosa assets in 

Louisiana to Hilcorp Energy I LLC for $110 million.

•	 Also in October 2011, BP completed the sale of its 35% interest in the 
Lan Tay and Lan Do gas fields in Vietnam to TNK-BP. The sale of BP’s 
interests in the associated pipeline completed in November 2011. The 
sale of BP’s interest in the Phu My 3 power generation plant is expected 
to complete in 2012. As at 31 December 2011, this was classified as 
assets held for sale.

•	 On 5 November 2011, BP received a notice from Bridas Corporation of 
termination of the agreement for their purchase of BP’s 60% interest 
in PAE. As a result of their decision and action, the share purchase 
agreement governing this transaction, originally agreed on 28 November 
2010, has been terminated. BP has repaid the deposit for the transaction 
of $3.5 billion received at the end of 2010. For details of payments in 
respect of the termination of restrictive covenants see page 85.

•	 On 1 December 2011, BP announced the sale of its Canadian Natural 
Gas Liquid (NGL) business to Plains All American Pipeline L.P. for  
$1.67 billion subject to closing adjustments. BP’s Canadian NGL 
business owns, operates and has contractual rights to assets involved 
in the extraction, gathering, fractionation, storage, distribution and 
wholesale marketing of NGLs across Canada and in the Midwest US.  
As at 31 December 2011 these assets were held as assets held for  
sale, awaiting completion of the sale.

•	 On 28 December 2011, BP completed the sale of its interests in the 
Pompano and Mica fields in the deepwater Gulf of Mexico to Stone 
Energy Corporation for $204 million. The sale includes BP’s 75% 
operated working interest in the Pompano field and assets and  
50% non-operated working interest in the Mica field, together with 
a 51% operated working interest in Mississippi Canyon block 29 and 
interests in certain leases located in the vicinity of the Pompano field.
•	 On 28 February 2012, BP announced it had agreed terms with LINN 
Energy to sell BP’s Hugoton basin assets (including the Jayhawk 
NGL Plant). Under the agreement, LINN Energy has agreed to pay BP 
$1.2 billion in cash. Completion of the agreement is subject to closing 
conditions including the receipt of all necessary governmental and 
regulatory approvals. The sale is currently expected to complete on 
30 March 2012.

The following discussion reviews operations in our Exploration and 
Production business by continent and country, and lists associated 
significant events that occurred in 2011. BP’s percentage working 
interest in oil and gas assets is shown in brackets. Working interest is the 
cost-bearing ownership share of an oil or gas lease. Consequently, the 
percentages disclosed for certain agreements do not necessarily reflect the 
percentage interests in reserves and production.

Europe
United Kingdom
BP is the largest producer of hydrocarbons in the UK. Key aspects of our 
activities in the North Sea include a focus on in-field drilling and selected 
new field developments.
•	 On 16 November 2010, production from the Rhum gas field in the 

central North Sea was suspended in relation to certain aspects of the 
EU sanctions. This action was taken to comply with the notification 
requirements in the relevant EU Regulation. Rhum is owned by BP 
(50%) and the Iranian Oil Company (50%) under a joint operating 

BP Annual Report and Form 20-F 2011    83

Business review: BP in more depthBusiness reviewagreement dating back to the early 1970s. Rhum remains shut-in. The 
restart and safe operation of Rhum remains contingent on the availability 
of third parties to provide services to Rhum. Such services are not as yet 
all available and it is presently unclear when resumption of production 
may be possible.

•	 On 13 July 2011, BP and its co-venturers announced an agreement to 
progress a major redevelopment of the Schiehallion and Loyal oilfields 
to the west of the Shetland Islands. The investment of circa $5 billion 
in the redevelopment of the fields is expected to extend the field 
life to 2035. The project involves replacing the existing Schiehallion 
Floating, Production, Storage and Offloading (FPSO) vessel with a 
new FPSO which is scheduled to be installed in 2015. BP will have a 
36.3% ownership interest in the new FPSO. There will also be a major 
investment in the upgrading and replacement of the subsea facilities 
to enable full development of the reserves. Production is scheduled to 
commence from the new facilities in 2016.

•	 On 6 September 2011, BP and its co-venturers announced an agreement 
to invest up to $1.2 billion to progress a project to develop the Kinnoull 
reservoir in the central UK North Sea (BP 77.06%). The reservoir will 
be connected to BP’s Andrew platform, enabling production from the 
Andrew area to extend to 2021.

•	 On 13 October 2011, BP announced that a major milestone had been 

reached on the Devenick gas project (BP 88.7%) with the installation of 
a 600-tonne module to receive gas and condensate from the Devenick 
reservoir. Production from the field is due to commence in 2012.
•	 On 13 October 2011, BP announced the successful completion of a 

well drilled to establish a southwest extension of the Clair field, west of 
Shetland in the UK North Sea. This well confirmed recoverable oil from 
a new portion of the field, and also discovered oil in a new, shallower 
reservoir horizon. During 2012, a further seismic survey of the field is 
planned, to understand the reservoir structure in more detail.

•	 Also on 13 October 2011, BP announced that the UK government had 

granted BP and its partners Shell, ConocoPhillips and Chevron, approval 
to proceed with the $7.6 billion Clair Ridge project (BP 28.6%), the 
second phase of development of the Clair field.

Our activities in the Rest of Europe are in Norway.
•	 In 2011, the Valhall redevelopment project continued, with production 
switch-over to the new facility scheduled for 2012. The redevelopment 
consists of a new processing platform required as a result of the existing 
platform suffering subsidence from extraction of hydrocarbons and 
includes a ‘power from shore system’ eliminating all gas-fired equipment 
offshore.

•	 On 14 August 2011, the FPSO vessel for the Skarv field arrived on 

location in the Norwegian Sea. Hook up of risers and commissioning work 
is ongoing and production is due to commence at the Skarv field in 2012.

•	 On 6 October 2011, the Ula field on the Norwegian Continental Shelf 

celebrated 25 years of production.

North America
United States
Our activities within the US take place in three main areas: deepwater Gulf 
of Mexico, Lower 48 states and Alaska.

Deepwater Gulf of Mexico
For further information on the activities of BP’s Gulf Coast Restoration 
Organization established following the Deepwater Horizon oil spill, see 
pages 76-79.

BP is the largest producer of hydrocarbons and the largest acreage 
holder in the deepwater Gulf of Mexico, operating seven production hubs.
•	 Following BP’s success in lease sale 213 in March 2010, seven of the 

leases awarded in 2010 were executed in 2011 and a further five leases 
from the sale were awarded and executed in 2011.

•	 During 2011, preparations for safely restarting drilling operations in 
the Gulf of Mexico were progressed. In July 2011, BP announced 
the implementation of a new set of voluntary drilling standards for its 
operations in the Gulf of Mexico. The standards go beyond existing 
regulatory obligations and have been developed through lessons learned 
following the Deepwater Horizon oil spill in 2010. By the end of 2011 

84    BP Annual Report and Form 20-F 2011

there were five BP-operated deepwater rigs engaged in abandonment 
and appraisal activities in the Gulf of Mexico. A permit to drill an appraisal 
well at Kaskida was approved and drilling operations commenced in 
October. Looking forward to 2012, plans include the drilling of exploration, 
appraisal and development wells and the start-up of additional three rigs, 
subject to receiving approvals from the US regulators.

•	 On 7 September 2011, BP announced the drilling of a successful 

appraisal well in a previously untested northern segment of the Mad Dog 
field in the Gulf of Mexico. The well, located on Green Canyon Block 
738, approximately 140 miles south of Grand Isle, Louisiana, confirms 
a significant resource extension for the Mad Dog field complex, which 
includes the existing field, in production since 2005, and appraisal drilling 
of the Mad Dog South field in 2008 and 2009. Due to the materiality 
of the Mad Dog South finds, BP has been advancing development 
options to increase production from Mad Dog and has now sanctioned 
the final investment decision on Mad Dog Phase 2. This will be the first 
BP-operated, standalone facility in a decade and will develop significant 
additional resources through the addition of subsea water injection and 
installation of a new production host.

•	 On 14 December 2011, the Bureau of Ocean Energy Management held 
its first western Gulf of Mexico lease sale since August 2009. BP bid on 
leases for 15 blocks and expects to be awarded leases for 11 blocks in 
early 2012.

Lower 48 states
The North America Gas business operates onshore in the Lower 48 states 
producing natural gas, natural gas liquids and coalbed methane across nine 
states. In 2011, BP drilled 148 wells as operator across the US, including 
the Wyoming, San Juan, Anadarko, Arkoma and East Texas basins. BP also 
continues to participate in Eagle Ford, Fayetteville and other non-operated 
positions. For further information on the use of fracking in our shale gas 
assets see page 71.

Alaska
BP operates 15 North Slope oilfields (including Prudhoe Bay, Endicott, 
Northstar, and Milne Point) and four North Slope pipelines, and owns a 
significant interest in six other producing fields.
•	 The Point Thomson Unit (PTU) was terminated by administrative 

decision of the State of Alaska Department of Natural Resources (DNR) 
in November 2006 (BP 32%). ExxonMobil, the operator, and the other 
unit owners, including BP, appealed the unit termination in the Alaska 
Superior Court. On 11 January 2010, the Alaska Superior Court reversed 
the DNR’s administrative decision to terminate the unit, and in the 
second quarter of 2010, the State of Alaska Supreme Court granted 
the DNR’s petition for a limited review. Briefs have been submitted to 
the Alaska Supreme Court, and a decision is expected in 2012. In the 
meantime, ExxonMobil and the State of Alaska have also informed the 
other unit owners, including BP, that they have reached a preliminary 
settlement agreement. BP and the other owners asked to participate 
in the settlement discussions but were precluded. We are currently 
analysing the agreement.

•	 In light of the closure of the Denali operations (see page 88 for further 
details) BP continues to explore ways to commercialize its North Slope 
gas resources.

•	 On 29 November 2007, BP Exploration (Alaska) Inc. (BPXA) pled guilty 
to a misdemeanour violation under the US Water Pollution Control Act 
to settle the criminal allegations by the state and federal government 
related to leaks in 2006 from oil transit lines in the Prudhoe Bay unit. 
The penalty included payment of $20 million with three years’ probation 
that was due to expire on 29 November 2010. On 29 November 2009, 
a spill of approximately 360 barrels of crude oil and produced water was 
discovered beneath a ruptured frozen three-phase flow line running from 
a well pad to the Lisburne Processing Center. On 17 November 2010, 
the US Probation Officer filed a petition in federal district court to revoke 
BPXA’s probation based on an allegation that the Lisburne spill was a 
criminal violation of state or federal law. In November 2011, a hearing 
was held in federal court in Anchorage. On 27 December 2011, the  
court issued a final decision denying the government’s petition and 
releasing BPXA from probation. See page 165 in Legal proceedings for 
further details.

Business reviewCanada
In Canada, BP is focused on oil sands, and will use in situ steam-assisted 
gravity drainage (SAGD) technology. This uses the injection of steam 
into the reservoir to warm the bitumen so that it can flow to the surface 
through recovery wells. BP holds an interest in several oil sands leases 
through the Sunrise oil sands and Terre de Grace oil sands partnerships 
and the Pike Oil Sands joint venture. BP also develops and produces 
natural gas, markets natural gas and has significant exploration interests in 
the Canadian Beaufort Sea.
•	 The Pike Oil Sands joint venture and the Terre de Grace partnership 

successfully completed winter drilling programmes in 2011, which were 
conducted to further appraise in situ oil sands resources. In late 2011, 
Pike Phase 1 moved to project appraisal status.

•	 The Sunrise operator, Husky Energy Inc., commenced building facilities, 
drilling wells and creating operational systems to bring Phase 1 into 
production. First production of Phase 1 bitumen is expected in 2014, 
potentially building to 60,000 barrels per day gross capacity over the 
subsequent 24 months.

•	 Interpretation of the 3D seismic survey acquired in 2009 and the seismic 
data for the EL446 field acquired in 2010 in the Canadian Beaufort Sea 
continued in 2011 and is nearing completion.

South America
Brazil
•	 On 12 May 2011, after receiving approval from the Brazilian National 
Petroleum, Natural Gas and Biofuels Agency (ANP), BP concluded 
the purchase of Devon Energy do Brasil (later renamed BP Energy do 
Brasil), adding 10 exploration and production blocks to its portfolio. The 
acquired blocks give BP a diverse and broad deepwater exploration 
acreage position offshore Brazil, with interests in seven licence blocks 
in the Campos basin, one in the Camamu-Almada basin in water depths 
ranging from 330 to 9,100 feet (100 to 2,780 metres), as well as two 
onshore licences in the Parnaíba basin. The Campos basin blocks include 
three discoveries – Xerelete, Pre-Salt Wahoo, and Itaipú – and the Polvo 
Field in shallow water, which is currently producing around 19,000boe/d 
net. BP completed the drilling of Itaipú-2, the first appraisal well in the 
Itaipú deepwater discovery in November 2011 and is in the process of 
finishing a second appraisal well.

Argentina, Bolivia and Chile
BP conducts activity in the Southern Cone region of South America 
(Argentina, Bolivia and Chile) through PAE, an equity-accounted joint 
venture with Bridas Corporation in which BP has a 60% interest.
•	 Following the announcement in November 2011 of the termination of 

the sale of BP’s interest in PAE to Bridas, BP no longer classifies these 
assets as assets held for sale. Under the share purchase agreement 
BP was required to make a payment of $700 million to Bridas upon 
termination in full settlement of any and all past claims between the 
two companies and also as consideration for amendments to the PAE 
agreement which terminate certain legacy restrictive covenants among 
BP, PAE and Bridas. Subsequent to payment of this amount by BP in 
November 2011, Bridas returned this $700 million to BP claiming that the 
share purchase agreement was void; BP disputes this claim by Bridas 
and maintains that the share purchase agreement and its terms which 
survive termination (including the settlement and termination of legacy 
restrictive covenants) remain valid and binding. The $700 million returned 
to BP is shown in the balance sheet at 31 December 2011 within cash 
and cash equivalents and within current trade and other payables.

•	 On 24 January 2012, the Republic of Bolivia issued a press statement 
declaring its intent to nationalize PAE’s interests in the Caipipendi 
Operations Contract. No formal nationalization process has yet 
commenced. PAE and its shareholders BP and Bridas intend to 
vigorously defend their legal interests under the Caipipendi Operations 
Contract and available Bilateral Investment Treaties.

Trinidad & Tobago
BP holds exploration and production licences covering 917,000 acres 
offshore of the east coast. Facilities include 13 offshore platforms and one 
onshore processing facility. Production is comprised of oil, gas and natural 
gas liquids (NGLs).

•	 On 25 July 2011, BP announced that it had been awarded two 

deepwater exploration and production blocks by the government of the 
Republic of Trinidad & Tobago. The award was for a 100% interest in 
blocks 23(a) and TTDAA 14 offshore Trinidad’s east coast, both under 
PSAs. Government approval is expected in early 2012. These blocks will 
increase the acreage in the region by 889,000 acres.

•	 On 26 August 2011, BP announced that first gas had been achieved 
from the Serrette platform. Serrette, sanctioned in May 2009, has a 
design capacity of 1 billion cubic feet per day and may deliver a peak 
production of up to 500 million standard cubic feet per day. It is the fifth 
normally unmanned installation (NUI) to be designed and constructed in 
Trinidad & Tobago. The platform will tie into the Cassia B platform.

Africa
Angola
BP is present in four major deepwater licences offshore Angola (Blocks 15, 
17, 18 and 31) and is operator in Blocks 18 and 31. In addition, BP holds a 
13.6% interest in the first Angolan LNG project.
•	 During the second quarter of 2011, a 40-day planned maintenance 

shutdown was conducted on the Greater Plutonio field. Corrosion in 
the high pressure gas cooling systems had restricted operations from 
September 2010, necessitating a complex replacement project that was 
safely completed in June 2011.

•	 The Pazflor deepwater development, located in block 17 (BP 16.67%), 

came onstream on 24 August 2011, ahead of schedule. It encompasses 
a new build FPSO, 49 subsea wells, 180 kilometres of flowlines and 
10,000 tonnes of equipment on the seabed. Pazflor is expected to have 
a plateau production rate of 220,000boe/d gross which will come from 
the Perpetua, Hortensia, Acacia and Zinia fields. The FPSO has topside 
facilities to process both Oligocene and Miocene age oils.

•	 In December 2011, BP gained access to five new deepwater exploration 
and production blocks offshore Angola. These gave BP a leading position 
in Angola, with interests in nine blocks accounting for a total acreage of 
30,842km2. BP was awarded operatorship of Blocks 19 and 24 with 50% 
interest, and additional non-operating interests in Blocks 20 (20%) and 25 
(15%) covering 19,400km2 in the Kwanza and Benguela basins. BP has 
also taken a 40% stake in the 4,840km2 Block 26 in the Benguela basin, 
by agreeing a farm-in deal with Brazilian national oil company, Petrobras, 
which operates the block. The five new blocks, including block 26, cover 
a total area of 24,000km2 in water depths from 200 to 2,500 metres, and 
increase BP’s total Angolan acreage by 275%.

Algeria
BP is a partner with Sonatrach and Statoil in the In Salah (BP 33.15%) 
and In Amenas (BP 45.89%) projects, which supply gas to the domestic 
and European markets. BP is also in a joint venture with Sonatrach in 
the Rhourde El Baguel (REB) oilfield (BP 60%), an enhanced oil recovery 
project 75 kilometres east of the Hassi Messaoud oilfield. In addition, BP is 
in a joint venture with Sonatrach in the Bourarhet Sud block, located to the 
south west of In Amenas.
•	 In 2011, development of the In Salah Southern Fields was approved and 
the primary engineering contracts awarded. First gas is expected in 2014.
•	 On 22 December 2011, BP and Sonatrach reached an agreement for BP 

to withdraw from the REB PSA at the end of 2011.

Libya
In Libya, BP is in partnership with the Libyan Investment Authority (LIA) 
to explore acreage in the onshore Ghadames and offshore Sirt basins, 
covered under the exploration and production-sharing agreement ratified in 
December 2007 (BP 85%). BP’s total assets in Libya at 31 December 2011 
were $437 million. To date, all of the 3D seismic commitment has been 
completed but no exploration wells have yet been drilled.
•	 Due to the outbreak of civil unrest leading to the regime change in Libya, 
the BP office in Tripoli was closed on 21 February 2011 and our Libyan 
operations suspended. BP declared force majeure – the contractual 
mechanism which flows from the suspension of our activities in Libya 
and the imposition of sanctions. We intend to resume exploration 
activities with agreement of the new authorities, and when we are sure 
it is safe to do so. We are currently assessing how long it will take to 
re-establish exploration operations.

Business review: BP in more depthBusiness reviewEgypt
BP has a long-standing history in Egypt, successfully operating there 
for close to 50 years. To date BP with its partners has produced almost 
40% of Egypt’s entire oil production and supplies more than 35% of the 
domestic gas demand. BP’s total assets in Egypt at 31 December 2011 
were $8,784 million ($4,768 non-current and $4,016 current).
•	 The 25 January 2011 civil uprising resulted in the BP office in Cairo 

closing for a period of 10 days, reopening on 7 February. Production and 
operations were, and continue to be, unaffected. Parliamentary elections 
started in late November 2011 and are expected to run until mid-March 
2012. We continue to closely monitor the developing situation in the 
country and its potential impact on the business and our people.

•	 In October 2011, BP announced the Salmon gas discovery in the North 
El Burg (BP 50% and operator) offshore concession in the Nile Delta. 
Salmon is the third discovery in the concession, following the Satis 1 and 
Satis 3 gas discoveries. Further appraisal work to evaluate the resources 
is under way.

Asia
Western Indonesia
BP has a joint interest in Virginia Indonesia Company LLC (VICO), the 
operator of the Sanga-Sanga PSA (BP 38%) supplying gas to Indonesia’s 
largest LNG export facility, the Bontang LNG plant in Kalimantan. BP also 
participates in the Sanga-Sanga coalbed methane (CBM) PSA (BP 38%), a 
brownfield, unconventional development overlaying the conventional PSA. 
Sanga-Sanga CBM is the cornerstone of the BP Asia Pacific CBM growth 
strategy.
•	 In March 2011, the first CBM long-term production test well was tied 

into the system that supplies Bontang LNG plant.

•	 On 1 April 2011, BP signed four new CBM PSAs – Tanjung IV, Kapuas I, 
II, and III in the Barito Basin of Central Kalimantan, covering a contiguous 
area of approximately 4,800km2. BP holds a 44% interest in the 
Pertamina-operated Tanjung IV PSA, and a 45% operating interest in 
each of the Kapuas I, II, and III PSAs. Subsurface evaluation of the areas 
covered by the new PSAs is under way.

China
BP’s upstream activities in the country include production from the China 
National Offshore Oil Corporation (CNOOC) operated Yacheng offshore gas 
field (BP 34.3%) as well as deepwater exploration in the South China Sea’s 
Block 42/05 (BP 40.82%). Yacheng supplies gas to the Castle Peak Power 
Company for up to 70% of Hong Kong’s gas-fired electricity generation. 
Additional gas is sold to the Hainan Holdings Fuel & Chemical Corporation 
Limited.
•	 On 10 January 2011, BP announced that it had signed a new agreement 

with CNOOC for deepwater exploration in Block 43/11 in the South 
China Sea and government approval was received on 30 January 2012.

Azerbaijan
BP is the largest foreign investor in the country. BP operates two PSAs, 
Azeri-Chirag-Gunashli (ACG) and Shah Deniz, and also holds other 
exploration leases.
•	 In June 1996, when the Shah Deniz PSA was awarded, Oil Industries 
Engineering and Construction, an affiliate of the National Iranian Oil 
Company and assignor to the current Iranian interest holder, Naftiran 
Intertrade Co. Ltd (NICO), was selected as a Shah Deniz project 
participant by the State of Azerbaijan, and has a 10% non-operating 
interest under the Shah Deniz PSA. NICO also has a 10% or less, non-
operating, interest in both the Shah Deniz project gas marketing entity 
and its gas transportation entity, both of which were incorporated in 
2002 and derive from the award of the Shah Deniz PSA. Under article 
30 of the new EU Regulations concerning restrictive measures against 
Iran, any body, entity or holder of rights derived from an award of a 
PSA before the entry into force of the EU Regulations by a sovereign 
government other than Iran, shall not be considered an ‘Iranian person, 
entity or body’ for the purposes of the main operative provisions of the 
EU Regulations. As such, the restrictive measures do not apply to  
NICO and Shah Deniz continues to operate in full compliance with EU  
and US law.

86    BP Annual Report and Form 20-F 2011

•	 On 6 May 2011, the Parliament of the Republic of Azerbaijan ratified the 
new PSA between BP and the State Oil Company of Azerbaijan (SOCAR) 
on joint exploration and development of the Shafag-Asiman structure 
in the Azerbaijan sector of the Caspian Sea. The ratification follows the 
signing of the PSA in Baku in October 2010. Under the PSA, which has 
a 30-year term, BP will be the operator with 50% interest while SOCAR 
will hold the remaining 50% interest.

•	 Following the Memorandum of Understanding signed in June 2010 

between Turkey and Azerbaijan for gas sales and transportation of gas 
from the new Shah Deniz full field development to be sold to consumers 
in Turkey and across Europe, on 25 October 2011, Azerbaijan and Turkey 
signed a number of key gas export related agreements to enable Turkey 
to buy gas from Azerbaijan and to transit gas from Azerbaijan through 
Turkey to Europe. The documents signed included an intergovernmental 
agreement between the government of Azerbaijan and the government 
of Turkey, gas sales agreements between SOCAR and BOTAS and 
also between the Azerbaijan Gas Supply Company (AGSC) and BOTAS 
International Limited (BIL), a gas transit agreement between SOCAR 
and BIL and a framework agreement setting the general terms and 
conditions for transit of gas sourced from Azerbaijan through the territory 
of Turkey. The agreements provide a legal framework to regulate the 
sale of Shah Deniz gas to Turkey and its transportation to European 
markets through Turkey.

Russia
•	 In May 2011, BP announced that both the Rosnefta share swap 
agreement and the Arctic Opportunity, originally announced on 
14 January 2011, had terminated. This termination was a result 
of the deadline for the satisfaction of conditions precedent having 
expired following delays resulting from interim orders granted by the 
English High Court and a UNCITRAL arbitration tribunal. This followed 
applications brought by Alfa Petroleum Holdings Limited (Alfa) and OGIP 
Ventures Limited (OGIP) against BP International Limited (BPIL) and BP 
Russian Investments Limited (BPRIL) alleging breach of the TNK-BP 
shareholders agreement (SHA). These interim orders did not address 
the question of whether or not BP breached the SHA. The UNCITRAL 
arbitration proceedings with Alfa, Access and Renova (AAR) which 
are subject to strict confidentiality obligations are ongoing. See Legal 
proceedings on page 166 for further information.

TNK-BP
TNK-BP, an associate owned by BP (50%) and AAR (50%), is an integrated 
oil company operating in Brazil, Russia, Ukraine, Venezuela and Vietnam. 
TNK-BP’s strategic goal is to become an international oil and gas company 
with a leading position in the Russian oil and gas industry. BP’s investment 
in TNK-BP is reported in the Exploration and Production segment. From 
2012 onward TNK-BP will be reported as a separate operating segment,  
as explained more fully on page 80. The TNK-BP group’s major assets 
are held in OAO TNK-BP Holding. Other assets include OAO Slavneft, 
an equity-accounted joint venture. The workforce is comprised of more 
than 50,000 people. TNK-BP’s main board is currently comprised of four 
BP, four AAR, and one independent director, with two vacancies for 
independent directors. The boards of key TNK-BP subsidiaries have both 
BP and AAR directors. In December 2011, two independent non-executive 
directors of TNK-BP Limited, Gerhard Schroeder and James Leng, 
announced that they would be stepping down from their positions on the 
board at the end of 2011.
•	 Upstream, TNK-BP operates either directly, or through equity-accounted 
joint ventures, a number of oil and gas fields in Russia, Vietnam and 
Venezuela which produced approximately 1.99mboe/d in 2011.
•	 Downstream, TNK-BP has interests in six refineries in Russia and 
Ukraine (including Ryazan and Lisichansk and Slavneft’s Yaroslavl 
refinery), with throughput of approximately 711 thousand barrels per day 
in 2011. TNK-BP has over 1,400 branded retail stations in Russia and 
Ukraine.

‘Toplivozapravochny kompleks Sheremetyevo’, the operator of jet fuel 
storage and into-wing fuelling services at Sheremetyevo International 
Airport in Moscow.

•	 In June 2011, TNK-BP completed the acquisition from BP of stakes in 
three upstream assets in Venezuela. Acquisition of these assets was 
announced in October 2010.

•	 In October 2011, TNK-BP entered into an agreement with HRT Oil & Gas 
for the acquisition of a 45% stake in 21 blocks in the Brazilian Solimoes 
Basin. These oil and gas exploration blocks are operated by HRT Oil & 
Gas, and cover an area of approximately 48,000km2.

•	 Also in October 2011, TNK-BP announced that the Vietnamese Ministry 

of Investment and Trade granted TNK Vietnam, a Vietnam-based 
subsidiary of TNK-BP, the investment licence to operate offshore gas 
Block 6.1. TNK-BP acquired BP’s 35% stake in Block 6.1, an integrated 
gas to power project which contains the Lan Tay and Lan Do gas 
condensate fields. As part of the deal, TNK-BP also acquired BP’s 32.7% 
interest in the Nam Con Son Pipeline. Acquisition of these assets was 
announced in October 2010.

Middle East
Production in the Middle East consists principally of the production 
entitlement of associates in Abu Dhabi, where we have equity interests of 
9.5% and 14.67% in onshore and offshore concessions respectively. The 
Abu Dhabi onshore concession expires in January 2014 with a consequent 
reduction in production of approximately 140mb/d.
•	 In the first quarter of 2011, extended well test production began in Oman.
•	 In August 2011, the seismic survey of the Risha concession in Jordan 

was successfully completed.

India
•	 On 30 August 2011, BP and Reliance Industries Limited (RIL) announced 
the completion of BP’s acquisition of a 30% stake in 21 oil and gas PSAs 
that RIL operates in India, including the producing KG D6 block. BP paid 
RIL an aggregate consideration of $7.0 billion for the interests acquired 
in the 21 PSAs. Further performance payments of up to $1.8 billion could 
be paid in case of exploration success in certain blocks that result in 
the development of commercial discoveries. This step commenced the 
planned alliance which will operate across the gas value chain in India, 
from exploration and production to distribution and marketing.

•	 Five minority shareholders of OAO TNK-BP Holding (TBH) filed a civil 

•	 On 17 November 2011, the two companies formed a 50:50 joint venture 

action in Tyumen, Siberia, against BP Russia Investments Limited and 
BP p.l.c. seeking to recover alleged losses of $13 billion relating to BP’s 
attempt to form a strategic alliance with Rosneft in January 2011. The 
action was dismissed by the Tyumen court fully on its merits. The Omsk 
Appellate court confirmed the Tyumen court of first instance’s dismissal 
of the minority suits. See Legal proceedings on page 166 for further 
information.

•	 On 9 February 2012, BP reached agreement with its Russian partners 

in TNK-BP on temporary amendments to the memorandum and articles 
of association of TNK-BP Limited and the SHA that reduce quorum 
requirements to require presence of directors nominated by BP and 
AAR only. The amendments are aimed at enabling the continuing 
functioning of the board of directors of TNK-BP (board of directors) while 
two independent directors who recently resigned are being replaced. 
This change is currently set to expire on 31 March 2012, unless both 
independent directors are appointed earlier.

•	 On 9 February 2012, BP also reached agreement with its Russian 

partners in TNK-BP regarding certain changes to the management board 
of its main management company in Russia OAO TNK-BP Management 
(management board). The changes were aimed at restructuring and 
optimizing the management board, following the elimination of the 
deputy TNK-BP group chief executive officer role. The restructured 
management board will now consist of six people. BP will have the 
right to nominate the chairman of the management board, as well 
as two executive directors in charge of upstream and downstream 
respectively (the BP members). AAR will have the right to nominate 
two other executive directors (the AAR members). The sixth member 
— the chief financial officer — will be nominated by the chairman of the 
management board. The chairman of the management board will in time 
also have the right to nominate the executive directors, subject to prior 
concurrence by the respective shareholder. All of the aforementioned 
nominations will require approval by the board of directors as a majority 
matter, except for the chairman of the management board whose 
appointment will require approval as a unanimous reserved matter. As 
part of the agreement, BP and AAR agreed to approve the continued 
appointment of the chief executive officer and the appointment of their 
respective executive directors, with such appointments to expire no later 
than 31 December 2013.

•	 All other provisions of the SHA (including those related to the review 
of new business opportunities, the board of directors and dispute 
resolution) remain unchanged.

Sakhalin
BP has interests in Sakhalin through a joint venture company, Elvary 
Neftegaz, in which BP holds a 49% equity interest, and its partner, 
Rosneft, holds the remaining 51% interest. In 2011, the process to exit 
the licence areas held by Elvary Neftegaz and liquidate the joint venture 
commenced. This follows the write-down of BP’s investment at the end of 
2010 following an unsuccessful exploration programme.

for the sourcing and marketing of gas in India.

Iraq
Following a successful bid with PetroChina to run the Rumaila oilfield 
in June 2009, the technical service contract (TSC) became effective 
on 17 December 2009. BP holds a 38% working interest and is the 
lead contractor. Rumaila is one of the world’s largest oilfields and was 
discovered by BP in 1953 and comprises five producing reservoirs. BP 
together with its partners is actively refurbishing the wells and facilities. 
With the achievement of the improved production target on 25 December 
2010, BP and PetroChina became eligible for service fees pursuant to the 
TSC. In 2011 both companies lifted cargoes from the Basra terminal as 
payment for service fees due.

Australia
BP is one of seven partners in the North West Shelf (NWS) venture which 
has been producing LNG, pipeline gas, condensate, LPG and oil since the 
1980s. Six partners (including BP) hold an equal 16.67% interest in the 
gas infrastructure and an equal 15.78% interest in the gas and condensate 
reserves, with a seventh partner owning the remaining 5.32%. BP also has 
a 16.67% interest in the NWS oil reserves and related infrastructure. The 
NWS venture is currently the principal supplier to the domestic market in 
Western Australia and one of the largest LNG export projects in Asia with 
five LNG trainsa in operation. BP also holds a 5.375% interest in the  
Jansz-Io field which is part of the Greater Gorgon project (Chevron, 
ExxonMobil and Shell) and is currently being developed.
•	 In January 2011, BP announced that it had been awarded four 

deepwater offshore exploration blocks in the Ceduna Sub Basin 
within the Great Australian Bight, off the coast of South Australia. The 
exploration work is to be phased over six years with a 3D seismic survey 
covering approximately 12,500km2 commenced in November 2011 and 
continuing into 2012. Following interpretation of the seismic survey, BP 
will drill four deepwater wells in this frontier exploration basin.

Eastern Indonesia
BP has a 100% interest in an exploration asset, the North Arafura PSA, 
located on the coast of the Arafura Sea, 480 kilometres south east of our 
Tangguh LNG plant (BP 37.16% and operator) and covering an area of just 
over 5,000km2. In addition, BP owns a 32% interest in Chevron’s operated 
West Papua I and III PSAs, located circa 120 kilometres to the south of the 
Tangguh LNG plant (see Liquefied natural gas on page 88).
•	 In December 2011, BP signed contracts with the Government of 

Indonesia for two deepwater PSAs; West Aru I and II. The PSAs are 
located 500 kilometres south west of the North Arafura PSA and 200 
kilometres west of the Aru island group, covering areas of 8,100km2 and 
8,300km2 respectively. BP holds 100% interest in the PSAs and expects 
to commence seismic operations in the near future.

Business review: BP in more depthBusiness reviewMidstream activities
Oil and natural gas transportation
The group has direct or indirect interests in certain crude oil and natural 
gas transportation systems. The following narrative details the significant 
events that occurred during 2011 by country.

BP’s onshore US crude oil and product pipelines and related 

transportation assets are included under Refining and Marketing (see  
page 94).

Alaska
BP owns a 46.9% interest in the Trans-Alaska Pipeline System (TAPS), 
with the balance owned by four other companies. The TAPS transports 
crude oil from Prudhoe Bay on the Alaska North Slope to the port of 
Valdez in south-east Alaska. BP also owns a 50% interest in a joint venture 
company called ‘Denali – The Alaska Gas Pipeline’ (Denali).
•	 On 16 May 2011, Denali announced that its open season efforts did not 
result in the commitments necessary to continue work on the Alaska 
North Slope gas pipeline project. Denali also indicated that it planned to 
close out its operations over the remainder of 2011. As a 50% owner in 
Denali, BP, along with co-owner ConocoPhillips, was directly involved 
in the decision to terminate Denali’s activities. BP’s focus as an owner 
in Denali was to create a viable alternative for the owners of the North 
Slope gas resource to commercialize their gas. BP has determined that 
the North American natural gas market does not support the project at 
this time. The Denali effort marked an important step in advancing the 
industry understanding of the gas pipeline opportunity in Alaska. BP will 
continue to pursue ways to commercialize our Alaskan gas resource.

North Sea
In the UK sector of the North Sea, BP operates the Forties Pipeline System 
(FPS) (BP 100%), an integrated oil and NGLs transportation and processing 
system that handles production from more than 50 fields in the central 
North Sea. The system has a capacity of more than 1 million barrels per 
day, with average throughput in 2011 of 473mboe/d. BP also operates 
and has a 36% interest in the Central Area Transmission System (CATS), 
a 400-kilometre natural gas pipeline system in the central UK sector of 
the North Sea. The pipeline has a transportation capacity of 293mboe/d 
to a natural gas terminal at Teesside in north-east England. Average 
throughput in 2011 was 39mboe/d. CATS offers natural gas transportation 
and processing services. In addition, BP operates the Sullom Voe oil 
and gas terminal in Shetland and the Dimlington/Easington Terminals in 
Humberside. Dimlington and Easington form part of the southern gas 
assets that BP announced its intention to sell in February 2011 (see 
Disposals on page 83).

Asia
BP, as operator, holds a 30.1% interest in and manages the Baku-Tbilisi-
Ceyhan (BTC) oil pipeline. The 1,768-kilometre pipeline transports oil 
from the BP-operated ACG oilfield in the Caspian Sea to the eastern 
Mediterranean port of Ceyhan and has a capacity of 1.2 million barrels 
per day. BP is technical operator of, and holds a 25.5% interest in, the 
693-kilometre South Caucasus Pipeline, which takes gas from Azerbaijan 
through Georgia to the Turkish border and has a capacity of 780mmscf/d. 
In addition, BP operates the Azerbaijan section of the Western Export 
Route Pipeline between Azerbaijan and the Black Sea coast of Georgia  
(as operator of Azerbaijan International Operating Company).

Liquefied natural gas
Our LNG activities are focused on building competitively advantaged 
liquefaction projects, establishing diversified market positions to create 
maximum value for our upstream natural gas resources and capturing third-
party LNG supply to complement our equity flows. Assets and significant 
events in 2011 included:
•	 In Trinidad, BP’s net share of the capacity of Atlantic LNG trainsa 1, 
2, 3 and 4 is 6 million tonnes of LNG per year (292 billion cubic feet 
equivalent regasified). All of the LNG from Atlantic train 1 and most of 
the LNG from trains 2 and 3 is sold to third parties in the US and Spain 
under long-term contracts. All of BP’s LNG entitlement from Atlantic 
LNG train 4 and some of its entitlement from trains 2 and 3 is marketed 

88    BP Annual Report and Form 20-F 2011

via BP’s LNG marketing and trading business to a variety of markets 
including the US, the Dominican Republic, Spain, the UK, Japan, India 
and South Korea.

•	 We have a 10% equity shareholding in the Abu Dhabi Gas Liquefaction 

Company, which in 2011 supplied 5.76 million tonnes of LNG (297 billion 
cubic feet equivalent regasified).

•	 BP has a 13.6% share in the Angola LNG project, which is expected to 

receive approximately 1 billion cubic feet of associated gas per day from 
offshore producing blocks and to produce 5.2 million tonnes per annum 
of LNG (gross), as well as related gas liquids products. Construction and 
implementation of the project is proceeding and the plant is expected to 
start up in 2012.

•	 In Indonesia, BP is involved in two of the three LNG centres in the 

country. BP participates in Indonesia’s LNG exports through its holdings 
in the Sanga-Sanga PSA (BP 38%). Sanga-Sanga currently delivers 
around 13% of the total gas feed to Bontang, one of the world’s largest 
LNG plants. The Bontang plant produced more than 15 million tonnes of 
LNG in 2011.

•	 Also in Indonesia, BP has its first operated LNG plant, Tangguh (BP 

37.16%), in Papua Barat. The asset comprises of 14 producing wells, 
two offshore platforms, two pipelines and an LNG plant with two 
production trains with a total capacity of 7.6 million tonnes per annum. 
Tangguh supplies LNG to customers in China, South Korea, Mexico and 
Japan through long-term contracts. BP is currently progressing options to 
expand the Tangguh facilities.

•	 In Australia, BP is one of seven partners in the NWS venture. The joint 
venture operation covers offshore production platforms, trunklines, 
onshore gas and LNG processing plants and LNG carriers. BP’s net share 
of the capacity of NWS LNG trains 1-5 is 2.7 million tonnes per annum 
of LNG. BP is one of five partners in the Browse LNG venture (operated 
by Woodside) and holds approximately a 17% interest. A greenfield 
LNG development at a proposed state government LNG precinct in 
the Kimberley region is currently in the early design stage and remains 
subject to regulatory, company and partner approvals.

•	 BP has a 30% equity stake in the 7mtpa capacity Guangdong LNG 
regasification and pipeline project in south-east China, making it the 
only foreign partner in China’s LNG import business. The terminal is 
also supplied under a long-term contract with Australia’s NWS project in 
which BP has an interest.

•	 In both the Atlantic and Asian regions, BP is marketing LNG using BP 

LNG shipping and contractual rights to access import terminal capacity in 
the liquid markets of the US (via Cove Point and Elba Island), the UK (via 
the Isle of Grain) and Italy (Rovigo), and is supplying Asian customers in 
Japan, South Korea and Taiwan.

Gas marketing and trading activities
Gas and power marketing and trading activity is undertaken primarily in 
the US, Canada and Europe to market both BP production and third-party 
natural gas, to support group LNG activities and manage market price risk, 
as well as to create incremental trading opportunities through the use of 
commodity derivative contracts. Additionally, this activity generates fee 
income and enhances margins from sources such as the management of 
price risk on behalf of third-party customers. These markets are large, liquid 
and volatile. Market conditions have become more challenging over the 
past few years due to the availability of shale gas and increased pipeline 
builds in North America. This has resulted in limited basis differentials and 
faster changes in production volumes in response to price movements. 
However, new markets are continuing to develop with continental 
European markets opening up and LNG becoming more liquid. The 
business (including support functions) operates primarily from offices in 
Houston and London and employs around 1,500 people.

In connection with its trading activities, the group uses a range 
of commodity derivative contracts and storage and transport contracts. 
These include commodity derivatives such as futures, swaps and options 
to manage price risk and forward contracts used to buy and sell gas and 
power in the marketplace. Using these contracts, in combination with 
rights to access storage and transportation capacity, allows the group to 

 a See footnote a on page 87.

Business reviewaccess advantageous pricing differences between locations, time periods 
and arbitrage between markets. Natural gas futures and options are traded 
through exchanges, while over-the-counter (OTC) options and swaps are 
used for both gas and power transactions through bilateral and/or centrally-
cleared arrangements. Futures and options are primarily used to trade 
the key index prices, such as Henry Hub, while swaps can be tailored to 
price with reference to specific delivery locations where gas and power 
can be bought and sold. OTC forward contracts have evolved in both 
the US and UK markets, enabling gas and power to be sold forward in a 
variety of locations and future periods. These contracts are used both to 

sell production into the wholesale markets and as trading instruments to 
buy and sell gas and power in future periods. Storage and transportation 
contracts allow the group to store and transport gas, and transmit power 
between these locations. The group has developed a risk governance 
framework to manage and oversee the financial risks associated with this 
trading activity, which is described in Note 26 to the Financial statements 
on pages 217-222. The group’s trading activities in natural gas are managed 
by the integrated supply and trading function.

The range of contracts that the group enters into is described in 

Certain definitions – commodity trading contracts, on page 111.

Business review: BP in more depthBusiness reviewLicence expiry
The Abu Dhabi onshore concession expires in January 2014 with a 
consequent reduction in production of approximately 140mb/d. The group 
holds no other licences due to expire within the next three years that 
would have a significant impact on BP’s reserves or production.

Resource progression
BP manages its hydrocarbon resources in three major categories: prospect 
inventory, contingent resources and proved reserves. When a discovery 
is made, volumes usually transfer from the prospect inventory to the 
contingent resources category. The contingent resources move through 
various sub-categories as their technical and commercial maturity increases 
through appraisal activity.

At the point of final investment decision, most proved reserves will 

be categorized as proved undeveloped (PUD). Volumes will subsequently 
be re-categorized from PUD to proved developed (PD) as a consequence 
of development activity. When part of a well’s proved reserves depends 
on a later phase of activity, only that portion of proved reserves associated 
with existing, available facilities and infrastructure moves to PD. The first 
PD bookings will typically occur at the point of first oil or gas production. 
Major development projects typically take one to four years from the time 
of initial booking of proved reserves to the start of production. Changes to 
proved reserves bookings may be made due to analysis of new or existing 
data concerning production, reservoir performance, commercial factors, 
acquisition and disposal activity and additional reservoir development 
activity.

Volumes can also be added or removed from our portfolio through 

acquisition or divestment of properties and projects. When we dispose 
of an interest in a property or project, the volumes associated with our 
adopted plan of development for which we have a final investment 
decision will be removed from our proved reserves upon completion. 
When we acquire an interest in a property or project, the volumes 
associated with the existing development and any committed projects 
will be added to our proved reserves if BP has made a final investment 
decision and they satisfy the SEC’s criteria for attribution of proved status. 
Following the acquisition, additional volumes may be progressed to proved 
reserves from contingent.

Contingent resources in a field will only be re-categorized as proved 
reserves when all the criteria for attribution of proved status have been met 
and the proved reserves are included in the business plan and scheduled 
for development, typically within five years. The group will only book 
proved reserves where development is scheduled to commence after five 
years, if these proved reserves satisfy the SEC’s criteria for attribution of 
proved status and BP management has reasonable certainty that these 
proved reserves will be produced.

At the end of 2011, BP had material volumes of proved 

undeveloped reserves held for more than five years in Trinidad, as well as 
non-material volumes in Australia, Azerbaijan, Norway, the UK and the US, 
that are part of ongoing development activities for which BP has a historical 
track record of completing comparable projects in these countries. 
The volumes are being progressed as part of an adopted development 
plan where there are physical limits to the development timing such 
as infrastructure limitations, contractual limits including gas delivery 
commitments, late life compression and the complex nature of working in 
remote locations.

BP has a three year average track record (since the adoption of 

the modernised rules for reporting) of converting 20% of our proved 
undeveloped reserves (excluding disposals) to proved developed reserves. 
This equates to a turnover time of five years. We expect the turnover time 
to remain at or below five years and anticipate no increase in the volume of 
proved undeveloped reserves held for more than five years.

In 2011, we converted 1,062mmboe of proved undeveloped 

reserves to proved developed reserves through ongoing investment in 
our upstream development activities. Total development expenditure in 
Exploration and Production, excluding midstream activities, was $13,329 
million in 2011 ($10,194 million for subsidiaries and $3,135 million for 
equity-accounted entities). The major areas converted in 2011 were 
Argentina, Indonesia, Russia, Trinidad and the US. Revisions of previous 
estimates for proved undeveloped reserves are due to the impact of 

90    BP Annual Report and Form 20-F 2011

year-end price (net of 1%) and changes relating to field performance or 
well results (99%). The table below describes the changes to our proved

BP bases its proved reserves estimates on the requirement of reasonable 
certainty with rigorous technical and commercial assessments based on 
conventional industry practice. BP only applies technologies that have been 
field tested and have been demonstrated to provide reasonably certain 
results with consistency and repeatability in the formation being evaluated 
or in an analogous formation. BP applies high-resolution seismic data for 
the identification of reservoir extent and fluid contacts only where there is 
an overwhelming track record of success in its local application. In certain 
deepwater fields BP has booked proved reserves before production flow 
tests are conducted, in part because of the significant safety, cost and 
environmental implications of conducting these tests. The industry has 
made substantial technological improvements in understanding, measuring 
and delineating reservoir properties without the need for flow tests. To 
determine reasonable certainty of commercial recovery, BP employs a 
general method of reserves assessment that relies on the integration of 
three types of data: (1) well data used to assess the local characteristics 
and conditions of reservoirs and fluids; (2) field scale seismic data to 
allow the interpolation and extrapolation of these characteristics outside 
the immediate area of the local well control; and (3) data from relevant 
analogous fields. Well data includes appraisal wells or sidetrack holes, full 
logging suites, core data and fluid samples. BP considers the integration 
of this data in certain cases to be superior to a flow test in providing 
understanding of overall reservoir performance. The collection of data 
from logs, cores, wireline formation testers, pressures and fluid samples 
calibrated to each other and to the seismic data can allow reservoir 
properties to be determined over a greater volume than the localized 
volume of investigation associated with a short-term flow test. There is 
a strong track record of proved reserves recorded using these methods, 
validated by actual production levels.

Governance
BP’s centrally controlled process for proved reserves estimation approval 
forms part of a holistic and integrated system of internal control. It consists 
of the following elements:
•	 Accountabilities of certain officers of the group to ensure that there is 
review and approval of proved reserves bookings independent of the 
operating business and that there are effective controls in the approval 
process and verification that the proved reserves estimates and the 
related financial impacts are reported in a timely manner.

•	 Capital allocation processes, whereby delegated authority is exercised 

to commit to capital projects that are consistent with the delivery of the 
group’s business plan. A formal review process exists to ensure that 
both technical and commercial criteria are met prior to the commitment 
of capital to projects.

•	 Internal audit, whose role is to consider whether the group’s system 
of internal control is adequately designed and operating effectively to 
respond appropriately to the risks that are significant to BP.

•	 Approval hierarchy, whereby proved reserves changes above certain 

threshold volumes require central authorization and periodic reviews. The 
frequency of review is determined according to field size and ensures 
that more than 80% of the BP proved reserves base undergoes central 
review every two years, and more than 90% is reviewed centrally every 
four years.

Business reviewBP’s vice president of segment reserves is the petroleum engineer 
primarily responsible for overseeing the preparation of the reserves 
estimate. He has over 25 years of diversified industry experience with 
the past eight spent managing the governance and compliance of BP’s 
reserves estimation. He is a past member of the Society of Petroleum 
Engineers Oil and Gas Reserves Committee, a sitting member of the 
American Association of Petroleum Geologists Committee on Resource 
Evaluation and vice chair of the bureau of the United Nations Economic 
Commission for Europe Expert Group on Resource Classification.

For the executive directors and senior management, no specific 
portion of compensation bonuses is directly related to proved reserves 
targets. Additions to proved reserves is one of several indicators by 
which the performance of the Exploration and Production segment is 
assessed by the remuneration committee for the purposes of determining 
compensation bonuses for the executive directors. Other indicators include 
a number of financial and operational measures. 

BP’s variable pay programme for the other senior managers in the 

Exploration and Production segment is based on individual performance 
contracts. Individual performance contracts are based on agreed items 
from the business performance plan, one of which, if chosen, could relate 
to proved reserves.

Compliance
International Financial Reporting Standards (IFRSs) do not provide 
specific guidance on reserves disclosures. BP estimates proved reserves 
in accordance with SEC Rule 4-10 (a) of Regulation S-X and relevant 
Compliance and Disclosure Interpretations (C&DI) and Staff Accounting 
Bulletins as issued by the SEC staff.

By their nature, there is always some risk involved in the ultimate 

development and production of proved reserves, including, but not 
limited to, final regulatory approval, the installation of new or additional 
infrastructure, as well as changes in oil and gas prices, changes in 
operating and development costs and the continued availability of additional 
development capital. All the group’s proved reserves held in subsidiaries 
and equity-accounted entities are estimated by the group’s petroleum 
engineers.

BP’s estimated net proved reserves as at 31 December 2011
Seventy-five per cent of our total proved reserves of subsidiaries at  
31 December 2011 were held through unincorporated joint ventures (75% 
in 2010), and 33% of the proved reserves were held through  
such unincorporated joint ventures where we were not the operator  
(31% in 2010).

Our proved reserves are associated with both concessions (tax 

Total

and royalty arrangements) and agreements where the group is exposed to 
the upstream risks and rewards of ownership, but where our entitlement 
to the hydrocarbons is calculated using a more complex formula, such as 
PSAs. In a concession, the consortium of which we are a part is entitled to 
the proved reserves that can be produced over the licence period, which 
may be the life of the field. In a PSA, we are entitled to recover volumes 
that equate to costs incurred to develop and produce the proved reserves 
and an agreed share of the remaining volumes or the economic equivalent.

 c Liquids include crude oil, condensate, natural gas liquids and bitumen.
 d Proved reserves in the Prudhoe Bay field in Alaska include an estimated 82 million barrels on which 
a net profits royalty will be payable over the life of the field under the terms of the BP Prudhoe Bay 
Royalty Trust.
 e Includes 20 million barrels of crude oil in respect of the 30% minority interest in BP Trinidad and

 f Includes 310 million barrels of crude oil in respect of the 7.37% minority interest in TNK-BP.
 g Includes 2,759 billion cubic feet of natural gas in respect of the 30% minority interest in BP Trinidad 
and Tobago LLC.
 h Includes 174 billion cubic feet of natural gas in respect of the 6.27% minority interest in TNK-BP.
 i Total proved reserves held as part of our equity interest in TNK-BP is 4,802mmboe comprising 
100 million barrels in Venezuela, 14mmboe in Vietnam and 4,688mmboe in Russia. In 2011 BP 
aligned its reporting with TNK-BP by moving to a life of field reporting basis. Reasonable certainty 
of licence renewals is demonstrated by evidence of Russian subsoil law, track record of renewals 
within the industry and track record of success in obtaining renewals by TNK-BP. This has resulted 
in a 253mmboe increase in proved reserves.

Business review: BP in more depthBusiness reviewRefining and Marketing

Our Refining and Marketing segment is responsible for the refining, 
manufacturing, marketing, transportation, and supply and trading of crude 
oil, petroleum, petrochemicals products and related services to wholesale 
and retail customers. We have significant operations in Europe, North 
America and Asia, and we also manufacture and market our products 
across Australasia, southern Africa and Central and South America; in total 
we market our products in more than 70 countries.

The segment operates hydrocarbon value chains covering three 

main businesses: fuels, lubricants and petrochemicals. Previously we 
referred to lubricants and petrochemicals as international businesses, but 
to provide greater transparency of the performance of these businesses 
we are now providing our financial information separately for fuels, 
lubricants and petrochemicals.

The fuels businesses sell refined petroleum products including 
gasoline, diesel, aviation fuel and liquefied petroleum gas (LPG). Within 
this, the fuels value chains (FVCs) integrate the activities of refining, 
logistics, marketing, and supply and trading on a regional basis. This 
recognizes the geographic nature of the markets in which we compete, 
providing the opportunity to optimize our activities from crude oil purchases 
to end-consumer sales through our physical assets (refineries, terminals, 
pipelines and retail stations). In addition, we operate a global aviation fuels 
marketing business and an LPG marketing business.

Our lubricants business is involved in manufacturing and marketing 

lubricants and related services to markets around the world. We market 
lubricants to the automotive, industrial, marine, aviation and energy 
markets through our key brands of Castrol, BP and Aral. Our Castrol brand 
is a highly recognized and popular lubricant brand worldwide. Distinctive 
brands, cutting-edge technology and building and sustaining customer 
relationships are cornerstones to our approach to market and underpin our 
success. We are particularly strong in Europe and key Asia Pacific markets 
including India.

Our petrochemicals business operates on a global basis and 
includes the manufacture and marketing of petrochemicals that are 
used in many everyday products, such as plastic bottles and textiles for 
clothing. Technology is at the heart of our business and we own proprietary 
world class technology for each of our main products. Our technological 
advantage, operational experience and project execution track record 
has made us an attractive partner which leads to material and distinctive 
growth opportunities. Petrochemicals growth is focused on the demand 
centre of Asia.

Our market
Overall world economic growth slowed in 2011, as did growth in world 
oil consumption. Global oil demand grew by 0.7 million b/d, but in the 
OECD, demand contracted again after growing for the first time in five 
years in 2010. By contrast, there was demand growth in Australia and 
Japan, where oil partially replaced nuclear power after the earthquake and 
tsunami. Aggregate OECD oil demand in 2011 was 4.3 million b/d below 
the 2005 peak.

The annual average BP refining marker margin (RMM) in 2011 was 

16% higher than in 2010, averaging $11.64 per barrel. Margins followed 
a typical seasonal pattern, with a peak in the second quarter in the run-up 
to the summer driving season. The RMM is an environmental indicator, 
similar to those used by many of our competitors, and is weighted 
regionally based on our refining capacity in that part of the world. Each 
regional marker margin is based upon product yields and a marker crude oil 
deemed appropriate for the region.

The RMM uses regional crack spreads to calculate the margin 

indicator, and does not include estimates of fuel costs and other variable 
costs. The RMMs may not be representative of the margins achieved by 
BP in any period because of BP’s particular refinery configurations and 
crude and product slate. However, the RMM is useful for understanding 
the indicative refining margin environment that is available to refiners in 
each region.

In 2011, refining margins increased in all the main US regions, despite a 
contraction in domestic gasoline demand, with reduced gasoline import 
volumes compensated for by higher domestic crude runs.

In Europe, where diesel accounts for a large proportion of regional 

consumption, refining margins increased for a second year running despite 
the loss of Libyan sweet crude supplies for much of the year, as demand 
for commercial transport improved.

Refining margins also improved in Asia Pacific, averaging  
$14.57 per barrel due to continuing oil demand growth and the disruption 
to Japanese refining operations caused by the earthquake and tsunami.
US mid-continent crude oils (including West Texas Intermediate 

(WTI)) were heavily discounted throughout the year because of increasing 
production in the US mid-continent and Canada, coupled with constrained 
infrastructure for crude transportation. This particularly benefited BP’s 
location-advantaged refineries of Toledo and Whiting in the US Midwest. 
In addition, fuel oil price discounts versus crude oil widened in 2011, 
benefiting our highly upgraded refineries that produce relatively little 
fuel oil.

In oil markets in 2011, supply was hampered by geo-political 

issues and a series of technical problems in non-OPEC crude production. 
This supply deficit brought OECD stocks down from historical highs to 
near-average levels within the first nine months of the year. After very low 
volatility levels in the second half of 2009 and in 2010, 2011 saw a return 
towards more average volatility.

In lubricants, we saw modest improvement in demand for the 

automotive and industrial sectors early in the year, but this came under 
increasing pressure as the year progressed and by the fourth quarter 
demand was declining in many geographies. Base oil prices rose markedly 
in the first half of the year, increasing our input costs. We continued to 
see a gradual shift towards higher-quality and higher-margin premium and 
synthetic lubricants.

In the first half of 2011, the petrochemicals margin environment 

was markedly different from the second half, due to strong demand 
for purified terephthalic acid (PTA) coupled with supply interruptions in 
both PTA and paraxylene (PX) leading to robust margins. In contrast the 
second half of the year saw the installed capacity run normally along with 
significant new capacity coming onstream. In addition concerns over the 
global economy affected demand, leading to a rapid reduction in margins. 
Acetic acid had a similar margin profile to PTA with supply interruptions in 
the first half leading to higher margins followed by weaker margins in the 
second half of the year as additional capacity came onstream.

Our strategy
Refining and Marketing is the product and service-led arm of BP, focused 
on fuels, lubricants and petrochemicals products and related services. We 
aim to be excellent in the markets in which we choose to participate – 
those that allow BP to serve the major energy markets of the world. We 
pursue competitive returns and sustainable growth, underpinned by safe 
manufacturing operations and technology, as we serve customers and 
promote BP and our brands through high-quality products.

We are focused on a consistent set of priorities executed in a 
systematic and disciplined way. These priorities begin with safety and 
include excellence of execution, portfolio quality and integration and 
growing margin share via exposure to growth. This is all underpinned by a 
disciplined financial framework. We believe that we now have a platform 
to sustain a world-class downstream business, which will enable us to be 
a leader in each of our chosen markets. Over time, we expect to shift the 

94    BP Annual Report and Form 20-F 2011

Business reviewbalance of participation and capital employed from established to growth 
regions.

In March 2010, we set a target to shareholders to deliver a 
performance improvement of at least $2 billion by 2012 relative to a 2009 
baseline and we believe we are on track to deliver this by the end of 2012a. 
In addition, post-2012, we plan to grow our margin further through our 
focus on growth markets and expansion of our margin capture capability, 
which we expect to achieve through projects such as those described 
below.

In our fuels business, as previously announced, we are planning 

to dispose of our Texas City refinery and the southern part of the 
US West Coast FVC before the end of 2012. We are investing in our 
existing operations to sustain safe, compliant standards and selectively 
investing in cash margin capture projects. The largest of these projects 
is the repositioning of the Whiting refinery towards heavy feedstock 
advantage, which is already under way and scheduled to come onstream 
in the second half of 2013. In addition to the repositioning of the Whiting 
refinery, margin capture projects include the Cherry Point refinery clean 
diesel project, Toledo refinery continuous catalytic reforming project, 
Gelsenkirchen refinery margin improvement programme and the recently 
announced Brazil aviation acquisition (see Acquisitions and disposals 
section on page 97).

We are also well positioned for growth in our lubricants and 
petrochemicals businesses. In our lubricants business, around half of our 
profit growth in recent years has come from the emerging economies in 
non-OECD countries as we have expanded in these markets. We have 
a material presence in the Indian automotive lubricant market. These 
positions provide a strong base to capture further long-term growth. In 
petrochemicals around 45% of our capacity is in the demand centre of 
Asia. Growth options are enabled by our distinctive technology, operational 
capability and access through key strategic relationships. During 2011 
the latest example of our strategy deployment was the signing of a 
memorandum of understanding with IndianOil Corp (IOC) to explore the 
potential for establishing a 50:50 joint venture to invest in a 1 million tonne 
per annum (mtpa) acetic acid plant in Gujarat, India. The joint venture will 
use BP’s latest Cativa® catalyst and technology, while the associated 
gasification facilities would utilize petroleum coke feedstock from IOC. 
Additionally, in 2011 BP received local government approval for a 1.25mtpa 
PTA plant in Zhuhai, China, and is now seeking final central governmental 
approval.

From 2012 we plan to create a new revenue stream in 
petrochemicals through licencing our technology, beginning with our 
aromatics products of PX and PTA.

As part of our drive towards more efficient operations, we have 

been transforming our back office. In 2011, we made further progress on 
our global SAP implementation within the fuels and lubricants businesses. 
We also continued to expand the scale of our business service centres 
(BSCs). BSCs are regional centres for certain finance, operational 
procurement and IT services for the BP group.

 a This performance improvement will be measured by comparing Refining and Marketing’s 
replacement cost profit before interest and tax for 2009 with that of 2012, after adjusting for 
non-operating items, fair value accounting effects and the impact of changes in the refining margin 
and petrochemicals environment (including energy costs), foreign exchange impacts and price-lag 
effects for crude and product purchases. This adjusted measure of replacement cost profit before 
interest and tax is non-GAAP. We believe the measure is useful to investors because it is one that 
is viewed and closely tracked by management as an important indicator of segment performance.

Our performance
2011 performance
Safety and operational risk
Safety remains the top priority across BP, and we are committed to 
leadership in process safety and to ensuring that our operations are safe, 
compliant and reliable with regard to both personal and process safety.

Refining and Marketing utilizes the group’s operating management 

system (OMS). OMS provides a set of group-wide requirements and a 
systematic way of working to continuously improve the way we operate. 
(OMS is explained in more detail on page 65). While all Refining and 
Marketing entities have transitioned on to OMS, we continue to work to 
enhance local systems and processes at all our sites.

All our major manufacturing entities (refineries and petrochemicals 

sites) have been through two performance improvement cycles (PIC) of 
OMS, and all other entities across our FVCs will have completed their 
second PIC by the end of 2012. The PIC is a management review carried 
out within each entity of their local operating management system, which 
identifies areas where further actions can be taken to enhance our systems 
and processes. These actions are risk-prioritized and form an integral part 
of each entity’s annual and longer-term planning. Where appropriate, 
actions are aggregated to provide common solutions.

Direction and oversight of safety in Refining and Marketing is 

provided by the segment operating risk committee (SORC) chaired by the 
chief executive officer of Refining and Marketing. Monitoring of safety and 
compliance in our operations is conducted by the newly-formed safety 
and operational risk function, for which there is a Refining and Marketing 
segment team independent of the segment CEO.

As outlined on page 65, BP has further strengthened its risk review 
process, and this process was applied to Refining and Marketing to ensure 
that appropriate risk management and mitigating actions were prioritized 
throughout the segment.

We measure our personal safety performance through the 
employment of a recordable injury frequency (RIF) rate and a days away 
from work case frequency (DAFWCF) rate, as well as a severe vehicle 
accident rate.

In 2011, our RIF (measured by the number of recordable injuries 

to the BP workforce per 200,000 hours worked) was 0.37, slightly higher 
than the 2010 rate of 0.35. The 2011 DAFWCF (a subset of the RIF that 
measures the number of cases where an employee misses one or more 
days from work) was 0.108, compared with 0.114 in 2010. There was a 
significant improvement in the severe vehicle accident rate (SVAR) in 2011 
with 61 severe vehicle accidents compared with 77 in 2010.

While progress has been made in the area of personal safety, there 
were two workplace fatalities in 2011. These tragic events have been fully 
investigated, and the learnings shared and actioned.

Process safety is measured by the process safety incident index 
(PSII), a weighted index which reflects both the number and severity of 
events per 200,000 hours worked. The PSII for 2011 was 0.36, equal to 
the 2010 rate, and better than the 2009 rate of 0.48. While the number of 
PSII events has increased from 2010, the overall severity of the events has 
reduced.

In terms of operational integrity, the number of losses of primary 
containment (LOPC), a measure of unplanned or uncontrolled releases of 
material from primary containment, was 5% lower in 2011 than in 2010. 
The number of oil spills greater than one barrel was slightly higher in 2011 
(145) than 2010 (132) however the volumes of oil spills were significantly 
lower in 2011 than in 2010 at 0.4 million litres compared with 1.3 million 
litres respectively.

In our US refineries, we continue to implement the 

recommendations of the BP US Refineries Independent Safety Review 
Panel and regulatory bodies. See the Safety section on page 67 for further 
information on progress.

Prior years’ comparative financial information
The replacement cost profit before interest and tax for the year ended 
31 December 2010 of $5,555 million included a net gain for non-operating 
items of $630 million, mainly relating to gains on disposal, partly offset by 
restructuring charges. Almost half of this gain related to our petrochemicals 
business, mainly relating to the disposal of our share of BP’s interests in 
ethylene and polyethylene production in Malaysia to Petronas. In addition, 
fair value accounting effects had a favourable impact of $42 million relative 
to management’s measure of performance. The primary additional factors 
contributing to the increase in replacement cost profit before interest 
and tax compared with 2009 were improved operational performance 
in the FVCs, continued strong operational performance in lubricants and 
petrochemicals, and further cost efficiencies, as well as a more favourable 
refining environment. Against very good operational delivery, the results 
were impacted by a significantly lower contribution from supply and trading 
compared with 2009.

The replacement cost profit before interest and tax for the year 
ended 31 December 2009 of $743 million included a net charge for non-
operating items of $2,603 million. The most significant non-operating items 
were restructuring charges and a $1.6 billion one-off non-cash loss to impair 
all of the segment’s goodwill in the US West Coast FVC relating to our 
2000 ARCO acquisition. This resulted from our annual review of goodwill as 
required under IFRS and reflected the prevailing weak refining environment 
that, together with a review of future margin expectations in the FVC, led to 
a reduction in expected future cash flows.

lost due to turnaround activity and all planned mechanical, process and regulatory maintenance 
downtime.
 g Petrochemicals production includes 1,699kte of petrochemicals produced at our Gelsenkirchen and 
Mulheim sites in Germany for which the income is reported in our fuels business.

Replacement cost profit before interest and tax for the year ended 
31 December 2011 was $5,474 million, compared with $5,555 million for 
the previous year. The full-year results included a net loss for non-operating 
items of $602 million, compared with a gain of $630 million in 2010. The 
non-operating items in 2011 mainly related to impairment charges relating 
to our disposal programme, partially offset by gains on disposal. (See 
page 58 for further information on non-operating items). In addition, fair 
value accounting effects had a favourable impact of $63 million, compared 
to a favourable impact of $42 million in 2010. (See page 58 for further 
information on fair value accounting effects.)

After adjusting for non-operating items and fair value accounting 

effects, Refining and Marketing reported record earnings in 2011a.

Strong refinery operations enabled us to capture the benefits 

available in 2011 from BP’s location advantage in accessing WTI-based 
crude grades. Compared with 2010, the result also benefited from a higher 
refining margin environment and a stronger supply and trading contribution. 
These benefits were partly offset by a significantly higher level of 
turnarounds in 2011 than 2010 and negative impacts from increased 
relative sweet crude prices in Europe and Australia and the weather-related 
power outages in the second quarter.

In the fuels business, financial performance for the full year was 

impacted by the factors noted above. Operational performance was strong 
with Solomon refining availability at 94.8% and refinery utilisation at 88% 
for the year.

Performance in our lubricants business in 2011 was impacted by 

an increasingly difficult marketing environment characterized by significant 
base oil price increases and weaker demand. These impacts were partly 
offset by supply chain efficiencies, and the strength of our products and 
brands, which has allowed the increased cost of goods to be largely 
recovered in the market.

In our petrochemicals business, compared with 2010, the 2011 
result was negatively impacted by weakening market conditions as the 
year progressed, as additional Asian capacity came onstream during the 
year at a time of weaker demand. This was somewhat offset by the 
strength in aromatics margins and volumes in the first half of the year.

 a In 2011, there was a charge of $602 million for non-operating items and a favourable impact of 
$63 million for fair value accounting effects. After adjusting for these impacts, replacement cost 
profit before interest and tax was $6,013 million. This is a non-GAAP measure, which management 
believes is useful to investors because it is viewed and closely tracked by management as an 
important indicator of segment performance.

Business reviewAcquisitions and disposals
We have been managing our portfolio actively, investing in businesses 
where we have strengths in terms of location, configuration, integration, 
technology and brand, while divesting assets that do not display these 
strategic characteristics.
•	 We completed the divestment programme of non-strategic pipelines and 
terminals in the US East of Rockies and West Coast, announced in 2009.
•	 We completed the disposal of our fuels marketing businesses in Malawi, 
Namibia, Tanzania, Zambia and Zimbabwe following the 2010 disposal of 
the business in Botswana. This portfolio rationalization now allows us to 
focus our activities within the continent on South Africa and Mozambique.
•	 We also announced our intention to divest the Texas City refinery and the 
southern part of the US West Coast FVC, including the Carson refinery, 
roughly halving our US refining capacity. BP is aiming to complete the 
sales by the end of 2012 subject to signing definitive agreements for 
the sales and subsequent satisfaction of any legal, regulatory or other 
conditions. BP will ensure that the fulfilment of current regulatory 
obligations associated with the Texas City refinery is reflected in any 
transaction. These assets are classified as held for sale in the group 
balance sheet as at 31 December 2011.

•	 In December 2011, Air BP announced the purchase of aviation fuels 
assets at seven Brazilian airports from Shell Brasil Holding B.V. and 
Cosan S.A. Industria e Commercio for approximately $100 million. The 
acquisition will give Air BP access to several new airports in Brazil as 
well as increasing capacity at existing Air BP operations. This deal is 
expected to be completed in the first quarter of 2012 subject to regulatory 
approvals.

•	 In February 2012, we announced our intent to sell our bulk and bottled 

LPG marketing businesses in nine countries.

Fuels value chains
The six FVCs seek to optimize the activities of our assets across the supply 
chain: crude delivery to the refineries; manufacture of high-quality fuels; 
distribution through pipeline and terminal infrastructure; and marketing 
and sales to our customers on a regional basis (see map on pages 34-35). 
This integration, together with a focus on excellent execution and cost 
management as well as a strong brand, market presence and customer 
base, are key to our financial performance.

The FVC strategy focuses on feedstock-advantaged, upgraded, 

well-located refineries integrated into advantaged logistics and marketing. 
Consequently, in the US we intend to roughly halve our US refining capacity 
by the end of 2012 (subject to all necessary legal and regulatory approvals) 
(see also the Acquisitions and disposals section on this page).

In our remaining FVCs, we believe that we have a portfolio of 
well-located refineries, integrated with strong marketing positions offering 
the potential for improvement and growth. We currently own or have 
a share in 16 refineries, which refine crude oil and produce refined fuel 
products which we supply to retail and commercial customers. Strategic 
investments in our refineries are focused on securing the safety and 
reliability of our assets while improving our competitive position.

Key to our future refining capability is the Whiting refinery 
modernization project (WRMP), which will allow the capture of additional 
margin through the processing of heavy Canadian crudes. The project 
continued to make significant progress in 2011. The coker’s six new drums 
are now set in place, and the Southern Lights pipeline to Canada, and 
Whiting’s interconnection to it, are in operation. This new pipeline capability 
allows transport of diluent streams back to Canada which are used to 
dilute heavy Canadian oils to facilitate their flow back to the US. WRMP is 
expected to come onstream in the second half of 2013.

Fuels
Our fuels business is made up of six regionally organized integrated FVCs 
(as shown in the refineries table below), the Texas City refinery, our global 
aviation fuel and LPG marketing businesses, and a number of regionally-
focused fuels marketing businesses notably the UK, Turkey, China and 
France. At the end of 2011, the operating capital employed relating to the 
fuels business was approximately $44 billion.

 b Crude distillation capacity is gross rated capacity, which is defined as the highest average sustained 
unit rate for a consecutive 30-day period.
 c Refinery utilization is annual throughput divided by crude distillation capacity, expressed as a 
percentage.

Overall refinery throughputs decreased by 74mb/d in 2011 relative to  
2010, mainly due to the second quarter weather-related power outages  
in the US.

We continue to invest to develop the capability of producing cleaner 

fuels to meet the requirements of our customers and their communities. 
For example, in April 2011, BP announced a major investment in a new 
hydrotreater unit and hydrogen plant at our Cherry Point refinery, called 
the clean diesel project. This project will allow the refinery to produce fuels 
that meet ultra-low sulphur diesel (ULSD) standards for rail and marine 
diesel customers. In addition, the new hydrogen plant will allow improved 
operation of naphtha reforming units at the refinery.

In addition to refined petroleum products, we also blend and 

market biofuels at our refineries. Biogasoline (bioethanol) and biodiesel 
(hydrogenated vegetable oils and fatty acid methyl esters) continue to 
grow in volume, primarily in Europe and the US, as regulatory requirements 
demand heavier blending levels. Our response is to continue to develop 
blend capabilities and to work with regulators, biofuels supply chains and 
other stakeholders to improve the sustainability of the biofuels we blend 
and supply.

Downstream of our refineries, our priorities are to operate an 
advantaged infrastructure and logistics network (which includes pipelines, 
storage terminals and road or rail tankers), drive excellence in operational 
and transactional processes, and deliver compelling customer offers in the 
various markets in which we operate.

We supply fuel and related convenience services to retail 
consumers through company-owned and franchised retail sites, as well 
as other channels, including wholesalers and jobbers. We also supply 
commercial customers within the transport and industrial sectors.

Our retail network is largely concentrated in Europe and the US, 

but also has established operations in Australasia, and southern Africa. We 
have developed networks in China in two separate joint ventures, one with 
PetroChina and the other with China Petroleum and Chemical Corporation 
(Sinopec) and these joint ventures in China operate around 700 dual 
branded sites.

As at 31 December 2011, BP’s worldwide retail network consisted 

of some 21,800 sites across the US, Europe, Australia, New Zealand and 
southern Africa. This is a reduction of 300 since 2010, primarily due to 
a focus on fewer higher throughput sites and portfolio changes such as 
the southern African disposals. These retail sites are primarily branded 
BP, ARCO and Aral. We expect the number of sites to fall in 2012 as we 
dispose of the southern part of our US West Coast FVC. In 2011, branded 
fuels sales in the US continued to recover from the oil effects of the 
Deepwater Horizon oil spill, and market share stabilized but remained lower 
than before the oil spill, partly caused by the slowdown in US gasoline 
demand. We continue to invest in our fuels marketing in growing markets, 
for example in 2011, we piloted a new convenience retail offer in Poland 
with Carrefour.

 a The number of retail sites includes sites not operated by BP but instead operated by dealers, 
jobbers, franchisees or brand licensees that operate under a BP brand. These may move to or from 
the BP brand as their fuel supply or brand licence agreements expire and are renegotiated in the 
normal course of business. Retail sites are primarily branded BP, ARCO and Aral.
 b Excludes our interest in equity-accounted entities which are dual-branded.

Some of these retail sites include a convenience store which offers 
consumers a range of food, drink and other consumables and services in a 
convenient and innovative manner. The convenience offer includes brands 
such as ampm, Wild Bean Café and Petit Bistro and includes partnerships 
with leading retailers such as Marks & Spencer in the UK and Carrefour in 
Poland.

BP’s integrated supply and trading function is responsible for 

delivering value across the overall crude and oil products supply chain. 
This structure enables the optimization of BP’s FVCs to maintain a single 
interface with the oil trading markets and to operate with a single set 
of trading compliance processes, systems and controls. The oil trading 
business (including support functions) has trading offices in Europe, the 
US and Asia and employs around 1,500 people. This enables the function 
to maintain a presence in the more actively traded regions of the global 
oil markets in order to gain an overall understanding of the supply and 
demand forces across this market. It has a two-fold strategic purpose in 
our business.

First, it seeks to identify the best markets and prices for our crude 
oil, source optimal feedstocks for our refineries, and provide competitive 
supply for our marketing businesses. In addition, where refinery 
production is surplus to marketing requirements or can be sourced more 
competitively, it is sold into the market. Wherever possible, the group will 
look to optimize value across the supply chain. For example, BP will often 
sell its own crude and purchase alternative crudes from third parties for its 
refineries where this will provide incremental margin.

Second, the function seeks to create and capture incremental 
trading opportunities. It enters into the full range of exchange-traded 
commodity derivatives, over-the-counter (OTC) contracts and spot and 
term contracts (described in Certain definitions – commodity trading 
contracts on page 111). In order to facilitate the generation of trading 
margin from arbitrage, blending and storage opportunities, it also owns 
and contracts for storage and transport capacity. The group has developed 
a risk governance framework to manage and oversee the financial risks 
associated with this trading activity, see Financial statements – Note 26 on 
pages 217-222.

The group’s trading activities in oil are managed by the integrated 

supply and trading function. In order to carry out the unique delegations 
from the BP group, the integrated supply and trading function operates and 
enforces a robust system of internal control. The internal control systems 
operated by the regional business leads are augmented by internal support 
functions that provide independent oversight, including product control, 
risk, trade completion and accounting and reporting. They are further 
supported by regional and group ethics and compliance and group  
internal audit.

Aviation
Our global aviation business, Air BP, is one of the world’s largest and best 
known aviation fuels suppliers, serving many major commercial airlines 
as well as the general aviation and military sectors. We have marketing 
sales in excess of 450 thousand barrels per day. Air BP’s strategic aim is 
to grow its position in the core locations of Europe, the US, Australasia 
and the Middle East, while focusing its portfolio towards airports that offer 
long-term competitive advantage.

Business reviewLPG
Our global LPG marketing business sells bulk, bottled, automotive and 
wholesale LPG products in 10 countries, with sales of over 50 thousand 
barrels per day. As noted in the Acquisitions and disposals section, BP 
announced in February 2012 its intent to sell the bulk and bottled LPG 
businesses in nine countries, and will retain the autogas and wholesale 
LPG sales from refineries which will be integrated into the fuels value 
chains.

Lubricants
Our lubricants business manufactures and markets lubricants and related 
products and services to the automotive, industrial, marine, aviation and 
energy markets across the world. At the end of 2011, the operating capital 
employed relating to the lubricants business was approximately $5 billion 
including goodwill of around $3 billion (see Financial statements – Note 10 
on pages 206-207).

We organize our lubricants business into customer sectors. The 

automotive sector serves the needs of land-based vehicles including cars, 
trucks, motorbikes, buses, tractors, earth movers and other vehicles. 
Our industrial sector serves customers who run or maintain plant and 
equipment; our marine sector serves users of river and sea-going vessels; 
aviation serves aircraft operators and maintenance industries; and our 
energy sector serves the oil and gas and power industries.

In the automotive lubricants sector, which accounts for more than 

two-thirds of our lubricants sales, we supply lubricants and other related 
products and services to intermediate customers such as retailers and 
workshops. These, in turn, serve end-consumers such as car, truck and 
motorcycle owners.

BP’s marine lubricants business is one of the largest global 

suppliers of lubricants to the marine industry, with a global presence in 
over 800 ports. BP’s industrial lubricants business is a leading supplier to 
those sectors of the market involved in the manufacturing of automobiles, 
trucks, machinery components and steel. We are also a leading supplier of 
lubricants for the oil, gas and aviation industries. In the oil and gas industry 
we supply some of world’s largest production and drilling companies, and 
we estimate that we supply over 30% of the world’s subsea control fluids. 
In the aviation industry, we are the lubricants supplier for around 40% of 
the jet engines of the world’s commercial airlines.

We look to market and sell our products across the world. We sell 
products direct to our customers in around 45 countries and use approved 
local distributors for other geographies. Approximately 40% of our 
employees are located in non-OECD markets and around 20% of staff are 
located in China and India alone. We are particularly strong in Europe and 
key Asia Pacific markets including India.

Our lubricants business markets primarily through our major brands 
of Castrol and BP, and through the Aral brand in specific European markets, 
notably Germany. Castrol is a recognized brand worldwide and we believe 
it provides us with a significant competitive advantage.

Distinctive brands, superior technology and building and sustaining 
customer relationships remain the cornerstones of our long-term strategy.
Our participation in the value chain is focused on areas of 
competitive differentiation and strength. These fall into three main areas: 
the development of formulations and the application of cutting-edge 
technology; developing product brands and communicating the benefits 
that our products provide to our customers; and building and extending 
our relationships with customers so that our products and services are 
delivered in a manner which best meets their needs.

We have chosen not to participate at scale in base oil or additives 

manufacturing. We are, however, one of the largest purchasers of base oil 
in the market.

We participate in blending in locations where scale and competitive 

advantage can be sustained, or where customer service or security of 
supply are of critical importance and otherwise difficult to secure. We have 
a network of 27 wholly-owned and operated blending plants worldwide and 
joint ownership in five others operated by third parties.

Our focus is on developing premium products, and we often work 

alongside original equipment manufacturers (OEMs) in doing this. The new 
Castrol EDGE professional range was launched in 2011 to the franchised 
workshop market in Europe and Africa.

In 2011, approximately 45% of the lubricants replacement cost profit 
before interest and tax was generated from non-OECD markets.

Petrochemicals
Our petrochemicals business is global, with operations in the US, Europe 
and Asia. The business buys a range of feedstocks for input into our 
manufacturing units, the majority of which have been built and operate 
utilizing our proprietary technology. We manufacture and market four main 
product lines: purified terephthalic acid (PTA), paraxylene (PX), acetic acid, 
and, through joint ventures, olefins and derivatives (O&D). We also produce 
a number of other speciality petrochemicals products. At the end of 2011, 
the operating capital employed relating to the petrochemicals business was 
approximately $5 billion.

Our strategy is to leverage our industry-leading technology in the 
markets in which we choose to participate, to grow the business, and to 
deliver industry-leading returns. New investments are targeted principally in 
the higher-growth Asian markets. We both own and operate 100%-owned 
assets, and have also invested in a number of joint ventures in Asia, where 
our partners are leading companies within their domestic market.

PTA is a raw material used in the manufacture of polyesters used 

in fibres, textiles and film, and polyethylene terephthalate (PET) bottles. 
PTA production requires PX as a feedstock, which we produce in the US 
and Europe and buy in Asia. PTA is then reacted with glycol to produce 
polyester chips or fibres, which are in turn used to produce PET bottles, 
polyester fibres and various speciality products, including protective 
screens for computers and TVs. PX production is primarily from the mixed 
xylene stream produced in a reformer within a refinery.

Acetic acid is a versatile intermediate chemical used in a variety 

of products such as paints, adhesives and solvents, as well as in the 
production of PTA. In producing acetic acid, we purchase methanol and 
either make or buy carbon monoxide (CO). CO can be produced from a 
variety of hydrocarbon feedstocks, including natural gas, naphtha, fuel oil 
and coal.

Our O&D business is based in China and is focused on serving 
the Chinese and Asian markets. The SECCO joint venture between BP, 
Sinopec and its subsidiary, Shanghai Petrochemical Company, is our main 
O&D site and is BP’s single largest investment in China. BP also co-owns 
one other naphtha cracker site outside Asia, which is integrated with our 
Gelsenkirchen refinery in Germany.

The petrochemicals business runs 16 manufacturing sites in 
the UK, the US, Belgium, Germany, China, Indonesia, South Korea, 
Malaysia and Taiwan, including our joint ventures, and we also have two 
petrochemicals plants which are managed by the fuels business as they 
utilize feedstock from our Gelsenkirchen refinery.

Outlook
In 2012, we expect the overall economic environment to be challenging, 
with below-average growth. Emerging economies are likely to drive 
growth, while developing countries are expected to lag behind. We expect 
that refiners will continue to operate with excess capacity globally, despite 
the announced shutdown of refineries in the US East Coast and Europe. 
The RMM in 2012 is expected to remain in a range of $8-12 per barrel. We 
expect the differential between WTI and Brent crude to eventually return to 
lower levels as additional US pipeline capacity is brought online. The level 
of BP’s refinery turnaround activity is expected to be broadly similar in 2012 
compared with 2011.

We expect the marketing environment for lubricants to remain 
challenging given the outlook for global economic growth. Longer term 
however, we expect to see growth in global lubricants demand through to 
2020 as a result of continued growth in the number of vehicles, continuing 
industrialization in emerging markets, and expanding world trade. This 
growth is expected to be concentrated in non-OECD markets. Lubricants 
demand is also expected to continue to shift towards higher quality, 
premium products as new vehicles adopt advanced, smaller, more efficient 
engines placing greater demands on lubricant performance.

In the petrochemicals industry, we expect significant new capacity to come 
onstream in acetic acid and PTA in 2012, 7% and 15% of global capacity 
respectively. Demand is expected to remain robust in 2012, but not 
sufficient to absorb the additional capacity, hence we expect the margin 
environment to be weaker in 2012 than in 2011.

Our priorities in 2012 remain consistent with those in 2011 and 

2010. We will continue to focus on delivering safe, reliable and compliant 
operations, improving the performance of our integrated FVCs, and driving 
further cost efficiencies across all our businesses. We intend to increase 
our investment levels slightly in 2012 versus 2011 and 2010, focusing 
on key safety and operational integrity priorities, maintaining our quality 
manufacturing and marketing portfolio, strengthening our US East of 
Rockies FVC business through the Whiting refinery modernization project, 
and continuing to grow our advantaged petrochemicals business in China. 
We intend to continue to upgrade our portfolio through investments in 
advantaged assets and the completion of our divestment programme, 
including the US southern west coast FVC and the Texas City refinery, 
announced in February 2011.

Business reviewOther businesses and corporate

Other businesses and corporate comprises the Alternative Energy 
business, Shipping, Treasury (which includes interest income on the 
group’s cash and cash equivalents), and corporate activities worldwide. It 
also included the group’s aluminium business until its disposal in 2011.
The replacement cost loss before interest and tax for the year 
ended 31 December 2011 was $2,478 million, compared with $1,516 
million for the previous year. 2011 included a net charge for non-
operating items of $822 million. (See page 58 for further information 
on non-operating items.) The primary additional factors affecting 2011’s 
result compared with that of 2010 were significantly higher functional 
and corporate costs; loss of aluminium contribution following disposal 
of the group’s aluminium business in 2011; impacts of restructuring in 
the Alternative Energy business; higher Shipping losses, partly offset by 
improved foreign exchange hedging results.

The replacement cost loss before interest and tax for the year 
ended 31 December 2010 included a net charge for non-operating items of 
$200 million.

The replacement cost loss before interest and tax for the year 
ended 31 December 2009 included a net charge for non-operating items of 
$489 million.

The primary additional factors reflected in 2010’s result compared 
with that of 2009 were improved business performance, more favourable 
foreign exchange effects and cost efficiencies.

Alternative Energy
Alternative Energy comprises BP’s low-carbon businesses and future 
growth options outside oil and gas, which we believe have the potential to 
be a material source of low-carbon energy and are aligned with BP’s core 
capabilities. These are biofuels, wind and a range of strategic investments.

Our market
A more diverse mix of energy will be required to meet long-term future 
demand. BP’s own estimates suggest that global primary energy demand 
will increase by around 40% between 2010 and 2030. Supported by 
government policies, renewables’ global share of power generation, 
is expected to be 11% by 2030. Between 2010 and 2030, biofuels are 
expected to account for 23% of transport energy demand growtha.

Our performance
In 2011, our biofuels business acquired the Brazilian sugar and ethanol 
producer Companhia Nacional de Açúcar e Álcool (CNAA) for $705 million. 
Our wind business added 401MW of gross generation capacity during 
2011 (274MW net), with the commercial start-up of the Cedar Creek 2 and 
Sherbino 2 wind farms. At the end of 2011, BP began winding down its 
remaining solar operations as it prepares to exit the solar business.
Alternative Energy continues to make progress against its 
commitment to invest $8 billion in low-carbon businesses by 2015. Our 
investment since 2005 is $6.6 billionb.

 a BP Energy Outlook 2030.
 b The majority of costs have been capitalized, some were expensed under IFRS.

Biofuels
BP believes that it has a key technological role to play in enabling the 
transport sector to respond to the dual challenges of energy security and 
climate change. We have embarked on a focused programme of biofuels 
development based around the most efficient transformation of sustainable 
and low-cost sugars into a range of fuel molecules. BP continues to invest 
throughout the entire biofuels value chain, from sustainable feedstocks 
that minimize pressure on food supplies through to the development of the 
advantaged fuel molecule biobutanol, which has a higher energy content 
than ethanol and delivers improved fuel economy. See Technology – 
Alternative Energy on page 76 for further information.

BP has production facilities operating, or in the planning and 

construction phases, in the US, Brazil and the UK.

The 2011 CNAA acquisition included mills located in Goiás and 

Minas Gerais states that supply both Brazilian and international markets 
with ethanol. We have also increased our share in the Brazilian biofuels 
company, Tropical BioEnergia S.A., to 100%, by acquiring the remaining 
50% for cash consideration of approximately $71 million. The acquisition 
included an operating ethanol mill, located in Goiás state. BP now owns 
and operates three producing ethanol mills in Brazil, with a total crush 
capacitya of 7.2 million tonnes per annum. The blending and distribution 
of biofuels continues to be carried out by our Refining and Marketing 
segment, in line with regulation.

 a Crush capacity represents a maximum capacity to process biofuels feedstock.

Wind
In wind power, BP has focused its business in the US, where we have 
developed one of the leading wind portfolios.

During 2011, full commercial operations commenced at the Cedar 
Creek 2 wind farm in Colorado with a gross capacity of 251MW (BP 50%) 
and in Texas at the 150MW Sherbino 2 wind farm. Construction is nearly 
complete at a further Texas wind farm, the 225MW Trinity Hills facility, 
and construction has commenced at the 141MW Mehoopany wind farm in 
Pennsylvania, and at the 470MW Flat Ridge wind farm in Kansas.

BP increased its net wind generation capacity to 1,048MW during 

2011, an increase of 35% over the prior year.

 a Net wind capacity is the sum of the rated capacities of the assets/turbines that have entered into 
commercial operation, including BP’s share of equity-accounted entities. The equivalent capacities 
on a gross-JV basis (which includes 100% of the capacity of equity-accounted entities where BP 
has partial ownership) were 1,763MW in 2011, 1,362MW in 2010 and 1,237MW in 2009. This 
includes 32MW of capacity in the Netherlands which is managed by our Refining and Marketing 
segment.

Solar
BP has been involved in solar for more than 35 years and in the last two 
years the industry has changed radically into a low margin commodity 
market. At the end of 2011, BP began winding down its remaining solar 
operations as it prepares to exit the solar business. BP will take the 
necessary steps to transfer its obligations and assets to its affiliates or to 
third parties.

Emerging business and ventures
Our emerging business and ventures unit brings together BP’s venturing 
and carbon markets expertise with extensive carbon capture and storage 
capability. Through venturing we have 29 separate venturing investments 
spanning three broad areas: bioenergy, electrification and carbon solutions. 
We are able to deploy specialist carbon capture and storage capabilities on 
our own operations and to monitor CO2 storage opportunities, such as the 
In Salah gas field where we have injected almost 4 million tonnes of CO2 
since 2004.

In September 2011, SCS Energy, an independent power producer 
involved in clean power projects, acquired the Hydrogen Energy California 
joint venture project from BP and Rio Tinto.

Separately, the 400MW Hydrogen Power Abu Dhabi project 

with CCS is awaiting further decisions, including arrangements for CO2

Business review: BP in more depthBusiness reviewAluminium
During 2011, we terminated our interest in this business with the disposal 
of our wholly-owned subsidiary, ARCO Aluminum Inc., to a consortium of 
Japanese companies for cash consideration of $680 million.

Treasury
Treasury manages the financing of the group centrally, ensuring liquidity 
sufficient to meet group requirements and manages key financial risks 
including interest rate, foreign exchange, pension and financial institution 
credit risk. From locations in the UK, the US and the Asia-Pacific region, 
Treasury provides the interface between BP and the international financial 
markets and supports the financing of BP’s projects around the world. 
Treasury trades foreign exchange and interest rate products in the 
financial markets, hedging group exposures and generating incremental 
value through optimizing and managing cash flows. Trading activities 
are underpinned by the compliance, control, and risk management 
infrastructure common to all BP trading activities. For further information, 
see Financial statements – Note 26 on page 217.

Insurance
The group generally restricts its purchase of insurance to situations where 
this is required for legal or contractual reasons. Losses are borne as they 
arise, rather than being spread over time through insurance premiums with 
attendant transaction costs. This approach was reviewed following the 
Deepwater Horizon oil spill but the group concluded that it will continue 
with its current approach of not generally purchasing insurance cover.

transportation and storage. The project is a joint venture between BP 
(40%) and Masdar (60%).

Shipping
We transport our products across oceans, around coastlines and along 
waterways, using a combination of BP-operated, time-chartered and 
spot-chartered vessels. All vessels conducting BP activities are subject to 
our health, safety, security and environmental requirements. The primary 
purpose of our shipping and chartering activities is the transportation of 
our hydrocarbon products. In addition, we may use surplus capacity to 
transport third-party products.

International fleet
At the end of 2011, we had 53 international vessels (37 medium-size 
crude and product carriers, three very large crude carriers, one North Sea 
shuttle tanker, eight LNG carriers and four LPG carriers). All these ships are 
double-hulled. Of the eight LNG carriers, BP manages one on behalf of a 
joint venture in which it is a participant.

Regional and specialist vessels
In Alaska, we retain a fleet of four double-hulled vessels. Outside the US, 
we had 14 specialist vessels (two double-hulled lubricants oil barges and 
12 offshore support vessels).

Time-charter vessels
At the end of 2011 BP had 93 hydrocarbon-carrying vessels above 600 
deadweight tonnes on time-charter, all of which are double-hulled. All these 
vessels participate in BP’s time-charter assurance programme.

Spot-charter vessels
BP spot-charters vessels, typically for single voyages. These vessels are 
always vetted for safety assurance prior to each use.

Other vessels
BP uses various craft such as tugs, crew boats and seismic vessels in 
support of the group’s business. We also use sub-600 deadweight tonne 
barges to carry hydrocarbons on inland waterways.

Maritime security issues
At a strategic level, BP avoids known areas of pirate attack or armed 
robbery; where this is not possible for trading reasons and we consider 
it safe to do so, we will continue to trade vessels through these areas, 
subject to the adoption of heightened security measures.

2011 has seen continuing pirate activity in the Gulf of Aden, Indian 

Ocean (up to approximately 200 miles west of the Indian coast) and the 
Arabian Sea. Activity has further extended into the north Arabian Sea 
(approximately 200 miles south of Pakistan) and the southern Red Sea. 
Despite an increasing level of piracy activity the number of vessels actually 
attacked and/or hijacked has remained roughly the same as in 2010, and 
the percentage success rate of the pirates has reduced. This is as a result 
of stronger naval intervention off the Somali coast, heightened awareness 
of the threat, and protective measures adopted by transiting ships.

At present, we follow available military and government agency 
advice and are participating in protective group transits through the Gulf 
of Aden Internationally Recommended Transit Corridor. BP uses the 
protective measures recommended in the international shipping industry 
guide BMP 4 – Best Management Practices for Protection against Somalia 
Based Piracy, jointly published by industry bodies, including Oil Companies 
International Marine Forum and supported by military operations in the 
region.

We continue to monitor other areas where piracy is known to occur 

e.g. West Africa and the South China Sea.

102    BP Annual Report and Form 20-F 2011

Business reviewLiquidity and capital resources

Following the Deepwater Horizon oil spill in 2010, the group initially faced 
significant costs relating to the immediate response activities as well as 
significant uncertainty regarding the ultimate magnitude of its liabilities and 
timing of cash outflows. During 2011 the impact on the group’s liquidity 
and capital resources has stabilized, allowing steps to be taken to enhance 
the strength of the balance sheet.

The group’s long-term credit ratings are A (stable outlook) from 

Standard & Poor’s, strengthened from A (negative outlook) in July 2011, 
and A2 (stable outlook) from Moody’s Investor Services.

BP renegotiated its committed bank facilities during 2011 putting in 

place $6.9 billion of facilities with 25 international banking counterparties, 
mostly for a term of three years. In addition the group has increased 
its access to commercial bank letters of credit (LC) by putting in place 
committed LC facilities of $5.1 billion and secured LC arrangements of $2.2 
billion, to supplement its uncommitted and unsecured LC lines.

The disposal programme of $30 billion initially announced in 2010 
has been increased to $38 billion, for completion by the end of 2013. By 
the end of 2011 agreements had been signed for more than $21 billion, 
with cash receipts totalling $17 billion in 2010 and $2.7 billion in 2011.

BP accessed US and European capital markets throughout the year 

with bond issuances amounting to $10.7 billion in 2011.

A further $0.8 billion of US Industrial Revenue/Municipal bonds 
were re-issued in term-out mode of between three to 10 years during  
the year.

During 2011 BP repaid $2.9 billion of the $5.3 billion of borrowings 
raised in 2010 that were secured against working capital and other assets, 
or backed by future crude oil sales from BP’s interests in specific offshore 
Angola and Azerbaijan fields.

Financial framework
BP continues to refine its financial framework to support the pursuit of 
value growth for shareholders, while maintaining a secure financial base. 
BP intends to increase operating cash flowa by 50% in 2014 compared to 
2011b. Half of the increase will arise as the remaining payments into the 
Deepwater Horizon Oil Spill Trust fund complete by the end of 2012, and 
half from operations. BP plans to use half of the expected additional cash 
flows to increase investments and half for other purposes.

We intend to maintain a significant liquidity buffer and to reduce our 
net debt ratio to the lower half of the 10-20% gearing range over time. See 
Financial statements – Note 35 on page 230 for gross debt, which is the 
nearest equivalent measure to net debt on an IFRS basis, and for further 
information on net debt and net debt ratio.

 a Operating cash flow is net cash provided by (used in) operating activities, as stated in the group 
cash flow statement on page 181.
 b Assuming an oil price of $100 per barrel in 2014. The projection reflects our expectation that all 
required payments into the $20-billion trust fund will have been completed by the end of 2012. 
It does not reflect any cash flows relating to other liabilities, contingent liabilities, settlements or 
contingent assets arising from the Gulf of Mexico oil spill which may or may not arise at that time. 
See Financial statements – Note 43 on page 249, for further information on contingent liabilities.

Dividends and other distributions to shareholders
On 1 February 2011, BP announced the resumption of quarterly dividend 
payments, with a fourth-quarter 2010 dividend of 7 cents per share. The 
resumption followed the suspension of dividend payments for the first 
three quarters of 2010 announced in June 2010 in light of the Deepwater 
Horizon oil spill and commitments to fund the $20-billion Trust. The same 
level of dividend was maintained for the first three quarters of 2011.

The total dividend paid to BP shareholders in 2011 was $4.1 billion 

with shareholders also having the option to receive a scrip dividend, 
compared with $2.6 billion paid in 2010. The dividend is determined in US 
dollars, the economic currency of BP.

On 7 February 2012, BP announced a dividend of 8 cents per share 

in respect of the fourth quarter 2011.

During 2011 and 2010, the company did not repurchase any of 
its own shares. Details of purchases to satisfy requirements of certain 
employee share-based payment plans are set out on page 170.

Financing the group’s activities
The group’s principal commodity, oil, is priced internationally in US dollars. 
Group policy has generally been to minimize economic exposure to 
currency movements by financing operations with US dollar debt. Where 
debt is issued in other currencies, including euros, it is generally swapped 
back to US dollars using derivative contracts, or else hedged by maintaining 
offsetting cash positions in the same currency. The overall cash balances 
of the group are mainly held in US dollars or swapped to US dollars and 
holdings are well-diversified to reduce concentration risk. The group is not 
therefore exposed to significant currency risk, such as in relation to the 
euro, regarding its borrowings. Also see Risk factors on page 59 for further 
information on risks associated with the general macroeconomic outlook, 
including the stability of the eurozone and Financial statements – Note 26 
on page 217.

The group’s finance debt at 31 December 2011 amounted to $44.2 
billion (2010 $45.3 billion). Of the total finance debt, $9.0 billion is classified 
as short term at the end of 2011 (2010 $14.6 billion). The short-term 
balance includes $4.9 billion for amounts repayable within the next 12 
months relating to long-term borrowings (2010 $6.9 billion). Commercial 
paper markets in the US and Europe are a further source of short-term 
liquidity for the group to provide timing flexibility. At 31 December 2011, 
outstanding commercial paper amounted to $3.6 billion (2010 $1.0 billion). 
Also included within short-term debt at the end of 2010 was $6.2 billion 
relating to deposits received for announced disposal transactions still 
pending legal completion post the balance sheet date. At the end of 2011 
the balance was de minimis at $30 million.

We have in place a European Debt Issuance Programme (DIP) 

under which the group may raise up to $20 billion of debt for maturities 
of one month or longer. At 31 December 2011, the amount drawn down 
against the DIP was $11.6 billion (2010 $12.3 billion). In addition, the group 
has in place an unlimited US shelf registration statement under which it 
may raise debt with maturities of one month or longer. None of the capital 
market bond issuances since the Deepwater Horizon oil spill contain any 
additional financial covenants compared with the group’s capital markets 
issuances prior to the incident.

The maturity profile and fixed/floating rate characteristics of the 

group’s debt are described in Financial statements – Note 34 on page 229.
Net debt was $29.0 billion at the end of 2011, an increase of $3.1 

billion from the 2010 year-end position of $25.9 billion. The ratio of net 
debt to net debt plus equity was 20.5% at the end of 2011 (2010 21.2%). 
Net debt and the ratio of net debt to net debt plus equity are non-GAAP 
measures. We believe that these measures provide useful information to 
investors. Net debt enables investors to see the economic effect of gross 
debt, related hedges and cash and cash equivalents in total. The net debt 
ratio enables investors to see how significant net debt is relative to equity 
from shareholders. See Financial statements – Note 35 on page 230 for 
gross debt, which is the nearest equivalent measure on an IFRS basis, and 
for further information on net debt.

Included in net debt are cash and cash equivalents of $14.1 billion 
at 31 December 2011 (2010 $18.6 billion). BP manages its cash position 
to ensure the group has adequate cover to respond to potential short-term 
market illiquidity, and expects to maintain a strong cash position. Cash 
balances are pooled centrally where permissible, and deployed globally 
as required. Cash surpluses are deposited with creditworthy banks and 
money market funds with short maturities to ensure availability. The 
group holds $1.2 billion of cash outside the UK and it is not expected 
that any significant tax will arise on repatriation. Further information on 
the management of liquidity risk and credit risk is provided in Financial 
statements – Note 26 on pages 217-222, and on the cash position in 
Financial statements – Note 30 on page 223.

The group also has access to significant sources of liquidity in the 
form of committed bank facilities. At 31 December 2011, the group had 
available undrawn committed standby borrowing facilities of $6.9 billion 
(2010 $12.5 billion), made up of:
•	 $6.8 billion of standby facilities available to draw and repay by mid-March 

2014.

•	 625 million Chinese yuan ($0.1 billion) of 365-day standby facilities 

available to draw and repay until the second half of 2012.

During 2011 $7.2 billion of 364-day facilities expired and were not renewed.

ongoing ability to generate cash, including further disposal proceeds, the 
group has sufficient working capital for foreseeable requirements.

Uncertainty remains regarding the amount and timing of future 
expenditures relating to the Deepwater Horizon oil spill and the implications 
for future activities. See Risk factors on pages 59-63, and Financial 
statements – Note 2 on page 190, Note 36 on page 231 and Note 43 on 
page 249 for further information.

Off-balance sheet arrangements
At 31 December 2011, the group’s share of third-party finance debt of 
equity-accounted entities was $7,003 million (2010 $6,987 million). These 
amounts are not reflected in the group’s debt on the balance sheet.
The group has issued third-party guarantees under which amounts 
outstanding at 31 December 2011 are $415 million (2010 $404 million) in 
respect of liabilities of jointly controlled entities and associates and $1,430 
million (2010 $1,339 million) in respect of liabilities of other third parties. 
Of these amounts, $220 million (2010 $355 million) of the jointly controlled 
entities and associates guarantees relate to borrowings and for other  
third-party guarantees, $1,267 million (2010 $1,324 million) relates to 
guarantees of borrowings. Details of operating lease commitments, which 
are not recognized on the balance sheet, are shown in the table below and 
in Note 14 on page 208.

Contractual commitments
The following table summarizes the group’s principal contractual obligations at 31 December 2011, distinguishing between those for which a liability is 
recognized on the balance sheet and those for which no liability is recognized. Further information on borrowings and finance leases is given in Financial 
statements – Note 34 on page 229 and more information on operating leases is given in Financial statements – Note 14 on page 208.

 a Expected payments include interest payments on borrowings totalling $3,751 million ($896 million in 2012, $746 million in 2013, $582 million in 2014, $443 million in 2015, $333 million in 2016 and $751 
million thereafter), and exclude disposal deposits of $30 million included in current finance debt on the balance sheet.
 b The amounts are undiscounted. Environmental liabilities include those relating to the Gulf of Mexico oil spill, including liabilities for spill response costs.
 c Represents the expected future contributions to funded pension plans and payments by the group for unfunded pension plans and the expected future payments for other post-retirement benefits.
 d The future minimum lease payments are before deducting related rental income from operating sub-leases. In the case of an operating lease entered into solely by BP as the operator of a jointly controlled 
asset, the amounts shown in the table represent the net future minimum lease payments, after deducting amounts reimbursed, or to be reimbursed, by joint venture partners. Where BP is not the 
operator of a jointly controlled asset BP’s share of the future minimum lease payments are included in the amounts shown, whether BP has co-signed the lease or not. Where operating lease costs are 
incurred in relation to the hire of equipment used in connection with a capital project, some or all of the cost may be capitalized as part of the capital cost of the project.
 e Represents any agreement to purchase goods or services that is enforceable and legally binding and that specifies all significant terms. The amounts shown include arrangements to secure long-term 
access to supplies of crude oil, natural gas, feedstocks and pipeline systems. In addition, the amounts shown for 2012 include purchase commitments existing at 31 December 2011 entered into 
principally to meet the group’s short-term manufacturing and marketing requirements. The price risk associated with these crude oil, natural gas and power contracts is discussed in Financial statements 
– Note 26 on page 217.

104    BP Annual Report and Form 20-F 2011

Business reviewThe group expects its total capital expenditure, excluding acquisitions and asset exchanges, to be around $22 billion in 2012. The following table 
summarizes the group’s capital expenditure commitments for property, plant and equipment at 31 December 2011 and the proportion of that expenditure 
for which contracts have been placed. Capital expenditure is considered to be committed when the project has received the appropriate level of internal 
management approval. For jointly controlled assets, the net BP share is included in the amounts shown. Where operating lease costs are incurred in 
connection with a capital project, some or all of the cost may be capitalized as part of the capital cost of the project. Such costs are included in the 
amounts shown.

In addition, at 31 December 2011, the group had committed to capital expenditure relating to investments in equity-accounted entities amounting to $610 
million. Contracts were in place for $332 million of this total.

Net cash provided by operating activities for the year ended 31 December 
2011 was $22,154 million compared with $13,616 million for 2010, the 
increase primarily reflecting a reduction in the cash outflow in respect of 
the Gulf of Mexico oil spill from $16,019 million in 2010 to $6,813 million 
in 2011. Excluding the impacts of the Gulf of Mexico oil spill, net cash 
provided by operating activities was $28,967 million for 2011, compared to 
$29,635 million for 2010, a decrease of $668 million. Profit before taxation 
decreased by $1,018 million, working capital requirements increased by 
$1,509 million and income taxes paid increased by $1,879 million. These 
impacts were partially offset by a decrease of $2,622 million in the net 
impairment, gains and losses on sale of businesses and fixed assets, 
and an increase in dividends received from jointly controlled entities and 
associates of $2,104 million.

Net cash provided by operating activities for the year ended 

31 December 2010 was $13,616 million compared with $27,716 million 
for 2009, the reduction primarily reflecting a net cash outflow of $16,019 
million in respect of the Gulf of Mexico oil spill. Excluding the impacts of 
the Gulf of Mexico oil spill, profit before taxation increased by $10,986 
million and a decrease in working capital requirements contributed $842 
million. This higher profit before tax did not result in an equivalent net 
increase in operating cash flow because it included $4,854 million in 
net gains on disposals, net of impairments, a decrease of $1,160 million 
in depreciation, depletion, amortization and exploration expense, and a 
decrease of $787 million in the net charge for provisions, less payments, all 
of which are non-cash items.

Net cash used in investing activities was $26,633 million in 2011, 

compared with $3,960 million and $18,133 million in 2010 and 2009 
respectively. The increase in cash used in 2011 reflected a decrease 
of $14,222 million in disposal proceeds, including the impact of the 
repayment in 2011 of a $3,530 million disposal deposit received in 2010, 
following the termination of the Pan American Energy LLC sale agreement, 
and an increase of $8,441 million in acquisitions, net of cash acquired; of 
which $7.0 billion was for the Reliance transaction. The decrease in 2010 
compared with 2009 reflected an increase of $14,273 million in disposal 
proceeds and a decrease in capital expenditure and investments of $2,445 
million, partly offset by an increase in acquisitions of $2,469 million.

Net cash provided by financing activities was $482 million in 2011 
compared with $840 million net cash provided in 2010 and $9,551 million 
net cash used in 2009. The decrease in net cash provided in 2011 primarily 
reflected a decrease in net proceeds from long-term financing of $4,734 
million, and an increase in dividends paid of $1,445 million partly offset by a 
net increase in short-term debt of $5,846 million. The net increase in cash 
provided in 2010 compared with 2009 reflected a decrease in dividends 
paid of $7,957 million, an increase in net proceeds from long-term financing 
of $1,686 million and a decrease in net repayments of short-term debt of 
$786 million.

The group has had significant levels of capital investment for many 

years. Cash flow in respect of capital investment, excluding acquisitions, 
was $18.8 billion in 2011, $18.9 billion in 2010 and $21.4 billion in 2009. 
Sources of funding are completely fungible, but the majority of the group’s 
funding requirements for new investment come from cash generated by 
existing operations. The group’s level of net debt, that is debt less cash and 
cash equivalents, was $29.0 billion at the end of 2011, $25.9 billion at the 
end of 2010 and $26.2 billion at the end of 2009.

During the period 2009 to 2011, our total sources of cash amounted 
to $87 billion, while our total uses of cash amounted to $90 billion. The net 
cash usage of $3 billion, and the increase in cash and cash equivalents held 
of $6 billion, were financed by an increase in finance debt of $9 billion over 
the three-year period. During this period, the price of Brent crude oil has 
averaged $84.14 per barrel. The following table summarizes the three-year 
sources and uses of cash.

Disposal proceeds received during the three-year period exceeded cash 
used for acquisitions, as a result in particular of our ongoing disposal 
programme started in 2010. Net investment (capital expenditure and 
acquisitions less disposal proceeds) during this period averaged $16 billion 
per year. Dividends paid to BP shareholders totalled $17 billion during the 
three-year period, with no ordinary share dividends being paid in respect 
of the first three quarters of 2010. In the past three years, $4 billion has 
been contributed to funded pension plans. This is reflected in net cash 
provided by operating activities in the table above. The balance of cash and 
cash equivalents held has been increased in light of the group’s current 
circumstances, as noted above.

BP Annual Report and Form 20-F 2011    105

Business review: BP in more depthBusiness reviewTrend information
For information on external market trends, see Our market on pages 18-24.
We expect production excluding TNK-BP in 2012 to be broadly flat 
compared with 2011, after adjusting for divestments and at an oil price of 
$100 per barrel.

In Refining and Marketing, the level of BP’s refinery turnaround 
activity is expected to be broadly similar in 2012 compared with 2011. 
We also expect the marketing environment in fuels, lubricants and 
petrochemicals to remain subdued given the outlook for global demand.

In 2012, we expect the quarterly loss, excluding non-operating 

items, for Other businesses and corporate to average around $500 million. 
As in previous years, this is likely to be volatile on an individual quarterly 
basis.

We expect capital expenditure, excluding acquisitions and asset 

exchanges, to increase to around $22 billion in 2012, as we invest to grow 
in our Exploration and Production segment.

Having completed disposals of almost $20 billion during 2010 and 
2011 combined, we expect to make further disposals that would bring the 
total to $38 billion by the end of 2013.

We intend to reduce the net debt ratio to the lower half of the 

10–20% range over time. Net debt is a non-GAAP measure.

Depreciation, depletion and amortization in 2012 is expected to be 

around $1.0 billion higher than in 2011.

The discussion above contains forward-looking statements, 

particularly those regarding external market trends, the future level of 
production excluding TNK-BP, the expected level of turnarounds, the 
marketing environment in fuels, lubricants and petrochemicals, the 
expected quarterly loss for Other businesses and corporate, the expected 
level of capital expenditures, expectations regarding future disposals, net 
debt and net debt ratio, and future levels of depreciation, depletion and 
amortization. These forward-looking statements are based on assumptions 
that management believes to be reasonable in the light of the group’s 
operational and financial experience. However, no assurance can be given 
that the forward-looking statements will be realized. You should not rely on 
past performance as an indicator of future performance. You are urged to 
read the cautionary statement on page 5 and Risk factors on pages 59-63, 
which describe the risks and uncertainties that may cause actual results 
and developments to differ materially from those expressed or implied by 
these forward-looking statements. The company provides no commitment 
to update the forward-looking statements or to publish financial projections 
for forward-looking statements in the future.

106    BP Annual Report and Form 20-F 2011

Regulation of the group’s business

BP’s activities, including its oil and gas exploration and production, pipelines 
and transportation, refining and marketing, petrochemicals production, 
trading, alternative energy and shipping activities, are conducted in 
many different countries and are subject to a broad range of EU, US, 
international, regional and local legislation and regulations, including 
legislation that implements international conventions and protocols. These 
cover virtually all aspects of our activities and include matters such as 
licence acquisition, production rates, royalties, environmental, health and 
safety protection, fuel specifications and transportation, trading, pricing, 
anti-trust, export, taxes and foreign exchange.

The terms and conditions of the leases, licences and contracts 
under which our oil and gas interests are held vary from country to country. 
These leases, licences and contracts are generally granted by or entered 
into with a government entity or state owned or controlled company 
and are sometimes entered into with private property owners. These 
arrangements with governmental or state entities usually take the form of 
licences or production-sharing agreements (PSAs), although arrangements 
with the US government can be by lease. Arrangements with private 
property owners are usually in the form of leases.

Licences (or concessions) give the holder the right to explore for 

and exploit a commercial discovery. Under a licence, the holder bears the 
risk of exploration, development and production activities and provides the 
financing for these operations. In principle, the licence holder is entitled to 
all production, minus any royalties that are payable in kind. A licence holder 
is generally required to pay production taxes or royalties, which may be in 
cash or in kind. Less typically, BP may explore for and exploit hydrocarbons 
under a service agreement with the host entity in exchange for 
reimbursement of costs and/or a fee paid in cash rather than production.

PSAs entered into with a government entity or state owned or 

controlled company generally require BP to provide all the financing and 
bear the risk of exploration and production activities in exchange for a share 
of the production remaining after royalties, if any.

In certain countries, separate licences are required for exploration 

and production activities and, in certain cases, production licences are 
limited to only a portion of the area covered by the original exploration 
licence. Both exploration and production licences are generally for a 
specified period of time. In the US, leases from the US government 
typically remain in effect for a specified term, but may be extended beyond 
that term as long as there is production in paying quantities. The term of 
BP’s licences and the extent to which these licences may be renewed vary 
from country to country.

Frequently, BP conducts its exploration and production activities 
in joint ventures or co-ownership arrangements with other international 
oil companies, state owned or controlled companies and/or private 
companies. These joint ventures may be incorporated or unincorporated 
ventures, while the co-ownerships are typically unincorporated. Whether 
incorporated or unincorporated, relevant agreements will set out each 
party’s level of participation or ownership interest in the joint venture or co-
ownership. Conventionally, all costs, benefits, rights, obligations, liabilities 
and risks incurred in carrying out joint venture or co-ownership operations 
under a lease or licence are shared among the joint venture or co-owning 
parties according to these agreed ownership interests. Ownership of 
joint venture or co-owned property and hydrocarbons to which the joint 
venture or co-ownership is entitled is also shared in these proportions. 
To the extent that any liabilities arise, whether to governments or third 
parties, or as between the joint venture parties or co-owners themselves, 
each joint venture party or co-owner will generally be liable to meet these 
in proportion to its ownership interest (see Financial statements – Note 2 
in relation to the Gulf of Mexico oil spill). In many upstream operations, 
a party (known as the operator) will be appointed (pursuant to a joint 
operating agreement (JOA)) to carry out day-to-day operations on behalf of 
the joint venture or co-ownership. The operator is typically one of the joint 
venture parties or a co-owner and will carry out its duties either through its 
own staff, or by contracting out various elements to third-party contractors 
or service providers. BP acts as operator on behalf of joint ventures and 
co-ownerships in a number of countries where we have exploration and 
production activities.

Business reviewFrequently, work (including drilling and related activities) will be contracted 
out to third-party service providers who have the relevant expertise 
and equipment not available within the joint venture or the co-owning 
operator’s organization. The relevant contract will specify the work to 
be done and the remuneration to be paid and typically will set out how 
major risks will be allocated between the joint venture or co-ownership 
and the service provider. Generally, the joint venture or co-owner and 
the contractor would respectively allocate responsibility for and provide 
reciprocal indemnities to each other for harm caused to their respective 
staff and property. Depending on the service to be provided, an oil and gas 
industry service contract may also contain provisions allocating risks and 
liabilities associated with pollution and environmental damage, damage 
to a well or hydrocarbon reservoir and for claims from third parties or 
other losses. The allocation of those risks vary among contracts and are 
determined through negotiation between the parties.

In general, BP is required to pay income tax on income generated 
from production activities (whether under a licence or PSAs). In addition, 
depending on the area, BP’s production activities may be subject to a range 
of other taxes, levies and assessments, including special petroleum taxes 
and revenue taxes. The taxes imposed on oil and gas production profits 
and activities may be substantially higher than those imposed on other 
activities, for example in Abu Dhabi, Angola, Egypt, Norway, the UK, the 
US, Russia and Trinidad & Tobago.

Environmental regulation
BP operates in more than 80 countries and is subject to a wide variety 
of environmental regulations concerning our products, operations 
and activities. Current and proposed fuel and product specifications, 
emission controls and climate change programmes under a number of 
environmental laws may have a significant effect on the production, sale 
and profitability of many of our products.

United States
•	 The Clean Air Act (CAA) regulates air emissions, permitting, fuel 

specifications and other aspects of our production, distribution and 
marketing activities. Stricter limits on sulphur and benzene in fuels will 
affect us in future, as will actions on greenhouse gas (GHG) emissions 
and other air pollutants. Additionally, states may have separate, stricter 
air emission laws in addition to the CAA.

•	 The Energy Policy Act of 2005 and the Energy Independence and 

Security Act of 2007 affect our US fuel markets by, among other things, 
imposing renewable fuel mandates and imposing GHG emissions 
thresholds for certain renewable fuels. States such as California also 
impose additional fuel carbon standards.

•	 The Clean Water Act regulates wastewater and other effluent discharges 
from BP’s facilities, and BP is required to obtain discharge permits, install 
control equipment and implement operational controls and preventative 
measures.

•	 The Resource Conservation and Recovery Act regulates the generation, 

storage, transportation and disposal of wastes associated with our 
operations and can require corrective action at locations where such 
wastes have been released.

•	 The Comprehensive Environmental Response, Compensation and 

Liability Act (CERCLA) can, in certain circumstances, impose the entire 
cost of investigation and remediation on a party who owned or operated 
a site contaminated with a hazardous substance, or arranged for disposal 
of a hazardous substance at the site. BP has incurred, or expects to 
incur, liability under the CERCLA or similar state laws, including costs 
attributed to insolvent or unidentified parties. BP is also subject to claims 
for remediation costs under other federal and state laws, and to claims 
for natural resource damages under the CERCLA, the Oil Pollution Act 
of 1990 (OPA 90) (discussed below) and other federal and state laws. 
CERCLA also requires hazardous substance release notification.

There are also environmental laws that require us to remediate 

•	 The Toxic Substances Control Act regulates BP’s import, export and sale 

and restore areas damaged by the accidental or unauthorized release 
of hazardous substances or petroleum associated with our operations. 
These laws may apply to sites that BP currently owns or operates, sites 
that it previously owned or operated, or sites used for the disposal of its 
and other parties’ waste. Provisions for environmental restoration and 
remediation are made when a clean-up is probable and the amount of BP’s 
legal obligation can be reliably estimated. The cost of future environmental 
remediation obligations is often inherently difficult to estimate. 
Uncertainties can include the extent of contamination, the appropriate 
corrective actions, technological feasibility and BP’s share of liability. See 
Financial statements – Note 36 on page 231 for the amounts provided in 
respect of environmental remediation and decommissioning.

A number of pending or anticipated governmental proceedings 

against BP and certain subsidiaries under environmental laws could 
result in monetary sanctions. We are also subject to environmental 
claims for personal injury and property damage alleging the release of 
or exposure to hazardous substances. The costs associated with such 
future environmental remediation obligations, governmental proceedings 
and claims could be significant and may be material to the results 
of operations in the period in which they are recognized. We cannot 
accurately predict the effects of future developments on the group, such 
as stricter environmental laws or enforcement policies, or future events 
at our facilities, and there can be no assurance that material liabilities and 
costs will not be incurred in the future. For a discussion of the group’s 
environmental expenditure see page 71.

Approximately 56% of our fixed assets are located in the US 
and the EU. US and EU environmental, health and safety regulations 
significantly affect BP’s exploration and production, refining and marketing, 
transportation and shipping operations. Significant legislation and regulation 
in the US and the EU affecting our businesses and profitability includes the 
following:

of new chemical products.

•	 The Occupational Safety and Health Act imposes workplace safety and 
health requirements on our operations along with significant process 
safety management obligations.

•	 The Emergency Planning and Community Right-to-Know Act requires 
emergency planning and hazardous substance release notification as 
well as public disclosure of our chemical usage and emissions.

•	 The US Department of Transportation (DOT) regulates the transport of 

BP’s petroleum products such as crude oil, gasoline, and petrochemicals, 
and other hydrocarbon liquids.

•	 The Marine Transportation Security Act (MTSA), the DOT Hazardous 

Materials (HAZMAT) and the Chemical Facility Anti-Terrorism Standard 
(CFATS) regulations impose security compliance regulations on 
around 50 BP facilities. These regulations require security vulnerability 
assessments, security risk mitigation plans and security upgrades, 
increasing our cost of operations.

OPA 90 is implemented through regulation issued by the US Environmental 
Protection Agency (EPA), the US Coast Guard, the DOT, the Occupational 
Safety and Health Administration and various states, Alaska and the west 
coast states currently have the most demanding state requirements 
although regulation in the Gulf of Mexico has increased following the 
2010 Deepwater Horizon oil spill. There is an expectation that OPA 90 and 
its regulations will become more stringent in the future. The impact will 
likely be more rigorous preparedness requirements (the ability to respond 
over a longer period to larger spills), including the demonstration of that 
preparedness. There will be additional costs associated with this increased 
regulation. In 2012, we expect more unannounced exercises and potential 
penalties for any failure to demonstrate required preparedness even 
without any OPA 90 amendments.

As a consequence of the Deepwater Horizon oil spill we 

have become subject to claims under OPA 90 and other laws and 
have established a $20-billion trust fund for legitimate state and local 
government response claims, final judgments and settlement claims, 
legitimate state and local response costs, natural resource damages and 
related costs and legitimate individual and business claims. We are also 
subject to Natural Resource Damages claims and numerous civil lawsuits

Business review: BP in more depthBusiness reviewby individuals, corporations and governmental entities. The ultimate costs 
for these claims cannot be determined at this time. We also expect the 
industry in general, and BP in particular, to become subject to greater 
regulation and increased operating costs in the Gulf of Mexico in the 
future. For further disclosures relating to the consequences of the 2010 
Deepwater Horizon oil spill, see Legal proceedings on page 160.

On 31 March 2009, the United States filed a complaint seeking civil 
penalties and damages relating to oil leaks from oil transit lines operated by 
BP Exploration (Alaska) Inc. (BPXA) at the Prudhoe Bay unit on the North 
Slope of Alaska. (See Legal proceedings on page 165.) The complaint also 
involved claims related to asbestos handling, allegations of non-compliance 
at multiple facilities for failure to comply with EPA’s spill prevention plan 
regulations, and for non-compliance with US Department of Transportation 
orders and regulations. The parties settled the dispute and on 13 July 2011 
the Court entered a Consent Agreement in which BPXA agreed to pay a 
$25-million penalty and to perform certain injunctive measures over the 
next three years with respect to pipeline inspection and maintenance.

Various environmental groups and the EPA have challenged 

certain aspects of the air permits issued by the Indiana Department of 
Environmental Management (IDEM) for upgrades to the Whiting refinery. 
In response to these challenges, the IDEM has reviewed the permits and 
responded formally to the EPA. BP is in discussions with EPA, the IDEM 
and certain environmental groups over these and other CAA issues relating 
to the Whiting refinery. BP has also been in settlement discussions with 
EPA to resolve alleged CAA violations at the Toledo, Carson and Cherry 
Point refineries.

European Union
BP’s operations in the EU are subject to a number of current and proposed 
regulatory requirements that affect or could affect our operations and 
profitability. These include:
•	 The EU Climate and Energy Package and the Emissions Trading Scheme 

(ETS) Directive (see Greenhouse gas regulation on page 109).

•	 The EU Industrial Emissions Directive (IED) (revising and replacing the 

Integrated Pollution Prevention and Control Directive (IPPC) and several 
other industrial directives including the Large Combustion Plant Directive 
(LCPD)) are in the process of transposition by the EU Member States. 
The IED provides the framework for setting permits for major industrial 
sites. Relative to IPPC and LCPD, the IED imposes tighter emission 
standards for some large combustion plants and is more prescriptive 
regarding the setting of emission of limit values based on use of Best 
Available Techniques (BAT) in permits for other discharges to air and 
water. The emission limit values are informed by the Sector specific and 
cross-Sector BAT Reference documents (BREFs) which are reviewed 
periodically. The outcome of the review of several BREFs key to our 
major sites is expected in 2012/2013. The IED transposition and output 
from the BREF revisions may result in requirements for further emission 
reductions at our EU sites.

•	 The European Commission Thematic Strategy on Air Pollution and the 
related work on revisions to the Gothenburg Protocol and National 
Emissions Ceiling Directive (NECD) will establish national ceilings for 
emissions of a variety of air pollutants in order to achieve EU-wide health 
and environmental improvement targets. This may result in requirements 
for further emission reductions at our EU sites.

•	 The EU Regulation on ozone depleting substances (ODS), which 

implements the Montreal Protocol (Protocol) on ODS was most recently 
revised in 2009. It requires BP to reduce the use of ODS and phase 
out use of certain ODS substances. BP continues to replace ODS in 
refrigerants and/or equipment, in the EU and elsewhere, in accordance 
with the Protocol and related legislation. Methyl bromide (an ODS) is 
a minor by-product in the production of purified terephthalic acid in 
our petrochemicals operations. The progressive phase-out of methyl 
bromide uses may result in future pressure to reduce our emissions of 
methyl bromide.

108    BP Annual Report and Form 20-F 2011

•	 The EU Fuels Quality Directive affects our production and marketing of 
transport fuels. Revisions adopted in 2009 mandate reductions in the 
life cycle GHG emissions per unit of energy as described in Greenhouse 
gas regulation above, and tighter environmental fuel quality standards 
for petrol and diesel (for example see Greenhouse gas regulation on 
page 109).

•	 The EU Registration, Evaluation and Authorization of Chemicals (REACH) 
Regulation requires registration of chemical substances, manufactured 
in, or imported into, the EU in quantities greater than 1 tonne per annum 
per legal entity, together with the submission of relevant hazard and 
risk data. REACH affects our refining, petrochemicals, exploration and 
production, biofuels, lubricants and other manufacturing or trading/import 
operations.

•	 Having completed registration of all the substances that we were 

required to submit by the regulatory deadline of 1 December 2010, 
we are now preparing registration dossiers for those substances 
(manufactured or imported in amounts in the range 100-1,000 tonnes 
per annum/legal entity) that are due to be submitted before 1 June 
2013. Substances registered in 2010 are subject to evaluation and/
or authorization/restriction procedures by the authorities and this may 
impact activities, product sales and their profitability.

•	 In addition, Europe has adopted the UN Global Harmonization System 

for hazard classification and labelling of chemicals and products through 
the Classification Labelling and Packaging (CLP) Regulation. This 
requires us to assess the hazards of all of our chemicals and products 
against new criteria and will, over time, result in significant changes to 
warning labels and material safety data sheets. All our European Material 
Safety Data Sheets will need to be updated to include both REACH 
and CLP information. We have completed updates for all chemicals 
substances we manufacture and market in the EU by the compliance 
deadline of 3 January 2011, and have implemented a process to 
maintain compliance in our European operations. We have also notified 
the European Chemicals Agency of hazard classifications for our 
manufactured and imported chemicals, for inclusion in a publicly available 
inventory of hazardous chemicals. CLP will also apply to mixtures 
(e.g. lubricants) by 2015. Activities covered by both CLP and REACH 
are subject to possible enforcement activity by national regulatory 
authorities.

•	 In the UK, significant health and safety legislation affecting BP includes 
the Health and Safety at Work Act and regulations and the Control of 
Major Accident Hazards Regulations.

The EU Commission has proposed the adoption of a regulation on safety 
of offshore oil and gas prospection, exploration and production activities. 
The proposed regulation aims to introduce harmonized regulation of the 
potential environmental, health and safety impacts of the offshore oil and 
gas industry throughout EU waters. Although it is at an early stage in the 
legislative process, as published the proposal is not entirely aligned with 
the regime operating in the UK and could also, if adopted, have the effect 
of extending liability for clean-up and compensation of environmental 
damage to marine waters.

Environmental maritime regulations
BP’s shipping operations are subject to extensive national and international 
regulations governing liability, operations, training, spill prevention and 
insurance. These include:
•	 In US waters, OPA 90 imposes liability and spill prevention and planning 
requirements governing, among others, tankers, barges and offshore 
facilities. It also mandates a levy on imported and domestically produced 
oil to fund the oil spill response. Some states, including Alaska, 
Washington, Oregon and California, impose additional liability for oil 
spills.

•	 Outside US territorial waters, BP Shipping tankers are subject to 
international liability, spill response and preparedness regulations 
under the UN’s International Maritime Organization, including the 
International Convention on Civil Liability for Oil Pollution, the MARPOL, 
the International Convention on Oil Pollution, Preparedness, Response 
and Co-operation and the International Convention on Civil Liability 
for Bunker Oil Pollution Damage. In April 2010, a new protocol, the 

Business reviewHazardous and Noxious Substance (HNS) Convention 2010 was adopted 
to address issues that have inhibited ratification of the International 
Convention on Liability and Compensation for Damage in Connection 
with the Carriage of Hazardous and Noxious Substances by Sea 1996 
(the HNS Convention). This protocol will enter into force when at least 
12 states have agreed to be bound by it (four of the states must have at 
least 2 million gross tonnes of shipping) and contributing parties in the 
consenting states have received at least 40 million tonnes of contributing 
cargoes in the preceding year.

•	 International marine fuel regulations under International Maritime 

Organization (IMO) and International Convention for the Prevention 
of Pollution from Ships (MARPOL) regimes impose stricter sulphur 
emission restrictions on ships in EU ports and inland waterways and 
the North and Baltic seas since 2010 and with a stricter global cap on 
marine sulphur emissions beginning in 2012. Further reductions are to 
be phased in thereafter. These restrictions require the use of compliant 
heavy fuel oil (HFO) or distillate, or the installation of abatement 
technologies on ships. These regulations will place additional costs on 
refineries producing marine fuel, including costs to dispose of sulphur, 
as well as increased GHG emissions and energy costs for additional 
refining.

To meet its financial responsibility requirements, BP Shipping maintains 
marine liability pollution insurance to a maximum limit of $1 billion for each 
occurrence through mutual insurance associations (P&I Clubs) but there 
can be no assurance that a spill will necessarily be adequately covered by 
insurance or that liabilities will not exceed insurance recoveries.

Greenhouse gas regulation
Increasing concerns about climate change have led to a number of 
international climate agreements and negotiations are ongoing.
•	 The Kyoto Protocol commits the parties and other entities to meet 

emissions targets in the first commitment period from 2008 to 2012.

•	 The UN summit in Cancun in December 2010 where parties to the 
UN Framework Convention on Climate Change (UNFCCC) reached 
formal agreement on a balanced package of measures to 2020. The 
Cancun Agreement recognizes that deep cuts in global GHG emissions 
are required to hold the increase in global temperature to below 2°C. 
Signatories formally commit to carbon reduction targets or actions by 
2020. Around 114 countries, including all the major economies and many 
developing countries, have made such commitments supplemented 
currently by an additional 27 parties that have agreed to be listed as 
agreeing to the accord. Supporting those efforts, principles were 
agreed for monitoring, verifying and reporting emissions reductions; 
establishment of a green fund to help developing countries limit and 
adapt to climate change; and measures to protect forests and transfer 
low-carbon technology to poorer nations.

•	 In November 2011, parties to the UNFCCC conference in Durban (COP 
17) agreed several measures. One was a ‘roadmap’ for negotiating 
a legal framework by 2015 for action on climate change involving all 
countries by 2020, to close the ’ambition gap’ between existing GHG 
reduction pledges and what is required to achieve the goal of limiting 
global temperature rise to 2°C. Another was a second commitment 
period for the Kyoto Protocol, to begin immediately after the first period 
and run for five or eight years. However, it will not include the US, 
Canada, Japan and Russia, and quantitative targets and the rules for 
carry-over of allowances from the first commitment will not be agreed 
until the end of 2012.

These international concerns and agreements are reflected in national 
and regional measures to limit GHG emissions. Additional stricter 
measures can be expected in the future. These measures can increase 
our production costs for certain products, increase demand for competing 
energy alternatives or products with lower-carbon intensity and affect the 
sales and specifications of many of our products. Current measures and 
developments potentially affecting our businesses include the following:
•	 The European Union (EU) has agreed an overall GHG reduction target 
of 20% by 2020. To meet this, a ‘Climate and Energy Package’ of 
regulatory measures has been adopted including: national reduction 

targets for emissions not covered by the EU Emissions Trading Scheme 
(ETS); binding national renewable energy targets to double renewable 
energy in the EU including at least a 10% share of final energy in 
transport; a legal framework to promote carbon capture and storage 
(CCS); and a revised EU ETS Phase 3. EU ETS revisions include a GHG 
reduction of 21% from 2005 levels, a significant increase in allowance 
auctioning, an expanded scope (sectors and gases), no free allocations 
for electricity production but free allocations for energy-intense and trade 
exposed industrial sectors. The EU ETS regulates approximately one-
fifth of our reported 2011 global GHG emissions and can be expected 
to require additional expenditure from 2013 when Phase 3 comes into 
effect. Finally, EU energy efficiency policy is currently addressed via 
national energy efficiency action plans.

•	 Article 7a of the revised EU Fuels Quality Directive requires fuel suppliers 

to reduce the life cycle GHG emissions per unit of fuel and energy 
supplied in certain transport markets.

•	 Australia has committed to reduce its GHG emissions by at least 5% 

below 2000 levels by 2020. In support of this, a Clean Energy legislative 
package of 19 bills was passed in November 2011 which includes 
imposing a carbon price on the top 500 emitting entities meeting the 
thresholds in the bill. The carbon price is scheduled to take effect 
from 1 July 2012 with a fixed price of $23 Australian dollar (indexed to 
forecast inflation) until 1 July 2015, an international linked price (trading) 
with floor and ceiling prices from 1 July 2015 through to 1 July 2018, and 
a market based price (trading) forward. A certain portion of allowances 
will be distributed to ‘emission intensive trade exposed’ businesses for 
no cost; this transitional support decreases with time. The majority of our 
Australia business emissions will be subject to the pricing scheme and 
will require additional expenditures for compliance.

•	 New Zealand has agreed to cut GHG emissions by 10-20% below 
1990 levels by 2020, subject to a comprehensive global agreement 
for emissions reductions coming into force. New Zealand’s emission 
trading scheme (NZ ETS) commenced on 1 July 2010 for transport fuels, 
industrial processes, and stationary energy. The agriculture sector (45% 
of New Zealand’s GHG emissions) has been proposed to join the NZ ETS 
in January 2015. New Zealand also employs a portfolio of mandatory 
and voluntary complementary measures aimed at GHG reductions. A 
September 2011 review of the scheme recommended effective delays 
to near-term emissions reductions targets, citing a lack of international 
action on cutting emissions.

•	 In the US, with no current potential for passing comprehensive climate 
legislation, the US Environmental Protection Agency (EPA) continues to 
pursue regulatory measures to address GHGs under the Clean Air Act (CAA).
–  In late 2009, the EPA released a GHG endangerment finding to 

establish its authority to regulate GHG emissions under the CAA.
–  Subsequent to this, the EPA finalized regulations imposing light duty 

vehicle emissions standards for GHGs.

–   The EPA finalized the initial GHG mandatory reporting rule (GHGRR) 
in 2009 and continues to make amendments to the rule. The first 
reports under the GHGRR were due on or before 30 September 2011. 
The majority of BP’s US businesses were affected by the GHGRR 
and submitted their first GHG emissions reports to the EPA under the 
GHGRR on or before the 30 September 2011 deadline. In addition 
to direct emissions from affected facilities, producers and importers/
exporters of petroleum products, certain natural gas liquids, and GHG’s 
were required to report product volumes and notional GHG emissions 
should these products be fully combusted. The EPA released 
direct emission data and a small subset of product supplier data on 
11 January 2012, with certain ‘confidential business information’ 
protections, in a ‘tool enabled’ database which allows transparency 
to the individual facility/entity level. Release of the balance of the 
product supply data is expected soon along with release of additional 
non-confidential information which will enable aggregation of reported 
emissions to the highest level US parent company.

–   The EPA finalized permitting requirements for new or modified large 

GHG emission sources in 2010, with these regulations taking effect in 
January 2011 and the second phase taking effect on 1 July 2011. The 
EPA has committed to additional actions, beginning in 2012, relating 
to smaller sources of GHG emissions.

BP Annual Report and Form 20-F 2011    109

Business review: BP in more depthBusiness review–  In a legal settlement with environmental advocacy groups the 

EPA committed to propose regulations under their New Source 
Performance Standards (NSPS) for GHG emissions from refineries 
by December 2011 and to finalize these by November 2012; the EPA 
was unable to meet the December deadline, which may delay final 
rulemaking. The EPA has communicated that they are considering 
three options for these standards, energy management, command 
and control (source specific emission limits) and benchmarking (e.g. a 
Solomon-type GHG intensity index or variation).

–  Legal challenges to the EPA’s efforts to regulate GHG emissions 
through the CAA continue along with active political debate with 
the final content and scope of GHG regulation in the US remaining 
uncertain.

•	 A number of additional state and regional initiatives in the US will affect 
our operations. Of particular significance, California is seeking to reduce 
GHG emissions to 1990 levels by 2020 and to reduce the carbon 
intensity of transport fuel sold in the state. California implemented a 
low-carbon fuel standard in 2010 although a preliminary injunction filed in 
late December 2011 is preventing its implementation. California issued 
final rules for its cap and trade programme in December 2011, with the 
scheduled start of the scheme to begin January 2012, with obligations 
commencing in 2013.

•	 Canada has established an action plan to reduce emissions to 17% 

below 2005 levels by 2020 and the national government continues to 
seek a co-ordinated approach with the US on environmental and energy 
objectives. Additionally, Canada’s highest emitting province, Alberta, 
has been running a market mechanism to reduce GHG since 2007. 
Controversy, partially driven by perceived GHG intensity regarding 
Canadian oil sand produced crude, continues with some jurisdictions 
contemplating policies to restrict or penalize its use.

•	 China has committed to reducing carbon intensity of GDP 40-45% 

below 2005 levels by 2020 and increasing the share of non-fossil fuels 
in total energy consumption from 7.5% in 2005 to 15% by 2020. The 
country’s 12th (2011-2015) Development Programme has set the target 
to reduce carbon intensity by 17% within five years, and this national 
target has been deconstructed into provincial ones for local actions. 
Meanwhile, five provinces and eight cities were selected as pilots for 
low carbon development, and seven provinces/cities were formally 
given instruction to start emission trading trials. As part of the country’s 
energy saving programme, the government also requires any operating 
entity with annual energy consumption of 10 thousand tonnes of coal 
equivalent (7ktoe/a) to have an energy saving target for the next five 
years. A number of BP joint venture companies in China will be required 
to participate in this initiative.

110    BP Annual Report and Form 20-F 2011

Certain definitions

Unless the context indicates otherwise, the following terms have the 
meaning shown below:

Replacement cost profit
Replacement cost profit or loss reflects the replacement cost of supplies. 
The replacement cost profit or loss for the year is arrived at by excluding 
from profit or loss inventory holding gains and losses and their associated 
tax effect. Replacement cost profit or loss for the group is not a recognized 
GAAP measure.

BP believes that replacement cost profit before interest and 
taxation for the group is a useful measure for investors because it is 
the profitability measure used by management. See Selected financial 
information on page 56 for the nearest equivalent measure on an IFRS 
basis, which is ‘Profit (loss) for the year attributable to BP shareholders’.

Inventory holding gains and losses
Inventory holding gains and losses represent the difference between the 
cost of sales calculated using the average cost to BP of supplies acquired 
during the period and the cost of sales calculated on the first-in first-out 
(FIFO) method after adjusting for any changes in provisions where the 
net realizable value of the inventory is lower than its cost. Under the FIFO 
method, which we use for IFRS reporting, the cost of inventory charged 
to the income statement is based on its historic cost of purchase, or 
manufacture, rather than its replacement cost. In volatile energy markets, 
this can have a significant distorting effect on reported income. The 
amounts disclosed represent the difference between the charge (to the 
income statement) for inventory on a FIFO basis (after adjusting for any 
related movements in net realizable value provisions) and the charge 
that would have arisen if an average cost of supplies was used for the 
period. For this purpose, the average cost of supplies during the period 
is principally calculated on a monthly basis by dividing the total cost of 
inventory acquired in the period by the number of barrels acquired. The 
amounts disclosed are not separately reflected in the financial statements 
as a gain or loss. No adjustment is made in respect of the cost of 
inventories held as part of a trading position and certain other temporary 
inventory positions.

Management believes this information is useful to illustrate to 

investors the fact that crude oil and product prices can vary significantly 
from period to period and that the impact on our reported result under 
IFRS can be significant. Inventory holding gains and losses vary from 
period to period due principally to changes in oil prices as well as changes 
to underlying inventory levels. In order for investors to understand the 
operating performance of the group excluding the impact of oil price 
changes on the replacement of inventories, and to make comparisons 
of operating performance between reporting periods, BP’s management 
believes it is helpful to disclose this information.

Non-GAAP information on fair value accounting effects
BP uses derivative instruments to manage the economic exposure 
relating to inventories above normal operating requirements of crude oil, 
natural gas and petroleum products. Under IFRS, these inventories are 
recorded at historic cost. The related derivative instruments, however, are 
required to be recorded at fair value with gains and losses recognized in 
income because hedge accounting is either not permitted or not followed, 
principally due to the impracticality of effectiveness testing requirements. 
Therefore, measurement differences in relation to recognition of gains and 
losses occur. Gains and losses on these inventories are not recognized 
until the commodity is sold in a subsequent accounting period. Gains and 
losses on the related derivative commodity contracts are recognized in 
the income statement from the time the derivative commodity contract is 
entered into on a fair value basis using forward prices consistent with the 
contract maturity.

BP enters into commodity contracts to meet certain business 
requirements, such as the purchase of crude for a refinery or the sale 
of BP’s gas production. Under IFRS these contracts are treated as 
derivatives and are required to be fair valued when they are managed as 

Business reviewpart of a larger portfolio of similar transactions. Gains and losses arising 
are recognized in the income statement from the time the derivative 
commodity contract is entered into.

IFRS requires that inventory held for trading be recorded at its 
fair value using period end spot prices whereas any related derivative 
commodity instruments are required to be recorded at values based on 
forward prices consistent with the contract maturity. Depending on market 
conditions, these forward prices can be either higher or lower than spot 
prices resulting in measurement differences.

BP enters into contracts for pipelines and storage capacity, oil 

and gas processing and liquefied natural gas (LNG) that, under IFRS, are 
recorded on an accruals basis. These contracts are risk-managed using a 
variety of derivative instruments, which are fair valued under IFRS. This 
results in measurement differences in relation to recognition of gains and 
losses.

The way that BP manages the economic exposures described 

above, and measures performance internally, differs from the way these 
activities are measured under IFRS. BP calculates this difference for 
consolidated entities by comparing the IFRS result with management’s 
internal measure of performance. Under management’s internal measure 
of performance the inventory, capacity, oil and gas processing and LNG 
contracts in question are valued based on fair value using relevant forward 
prices prevailing at the end of the period and the commodity contracts for 
business requirements are accounted for on an accruals basis. We believe 
that disclosing management’s estimate of this difference provides useful 
information for investors because it enables investors to see the economic 
effect of these activities as a whole. The impacts of fair value accounting 
effects, relative to management’s internal measure of performance and a 
reconciliation to GAAP information is shown on page 58.

Commodity trading contracts
BP’s Exploration and Production and Refining and Marketing segments 
both participate in regional and global commodity trading markets in order 
to manage, transact and hedge the crude oil, refined products and natural 
gas that the group either produces or consumes in its manufacturing 
operations. These physical trading activities, together with associated 
incremental trading opportunities, are discussed further in Exploration and 
Production on pages 88-89 and in Refining and Marketing on page 98. 
The range of contracts the group enters into in its commodity trading 
operations is as follows.

Exchange-traded commodity derivatives
These contracts are typically in the form of futures and options traded on 
a recognized exchange, such as Nymex, SGX and ICE. Such contracts 
are traded in standard specifications for the main marker crude oils, such 
as Brent and West Texas Intermediate, the main product grades, such 
as gasoline and gasoil, and for natural gas and power. Gains and losses, 
otherwise referred to as variation margins, are settled on a daily basis 
with the relevant exchange. These contracts are used for the trading and 
risk management of crude oil, refined products, natural gas and power. 
Realized and unrealized gains and losses on exchange-traded commodity 
derivatives are included in sales and other operating revenues for 
accounting purposes.

Over-the-counter contracts
These contracts are typically in the form of forwards, swaps and options. 
Some of these contracts are traded bilaterally between counterparties; 
others may be cleared by a central clearing counterparty. These contracts 
can be used both for trading and risk management activities. Realized and 
unrealized gains and losses on OTC contracts are included in sales and 
other operating revenues for accounting purposes.

The main grades of crude oil bought and sold forward using 

standard contracts are West Texas Intermediate and a standard North 
Sea crude blend (Brent, Forties and Oseberg or BFO). Although the 
contracts specify physical delivery terms for each crude blend, a significant 
number are not settled physically. The contracts typically contain standard 
delivery, pricing and settlement terms. Additionally, the BFO contract 
specifies a standard volume and tolerance given that the physically settled 
transactions are delivered by cargo.

Gas and power OTC markets are highly developed in North America and 
the UK, where the commodities can be bought and sold for delivery in 
future periods. These contracts are negotiated between two parties to 
purchase and sell gas and power at a specified price, with delivery and 
settlement at a future date. Typically, these contracts specify delivery 
terms for the underlying commodity. Certain of these transactions are not 
settled physically, which can be achieved by transacting offsetting sale 
or purchase contracts for the same location and delivery period that are 
offset during the scheduling of delivery or dispatch. The contracts contain 
standard terms such as delivery point, pricing mechanism, settlement 
terms and specification of the commodity. Typically, volume and price are 
the main variable terms.

Swaps are often contractual obligations to exchange cash flows 

between two parties: a typical swap transaction usually references a 
floating price and a fixed price with the net difference of the cash flows 
being settled. Options give the holder the right, but not the obligation, to 
buy or sell crude, oil products, natural gas or power at a specified price on 
or before a specific future date. Amounts under these derivative financial 
instruments are settled at expiry. Typically, netting agreements are used to 
limit credit exposure and support liquidity.

Spot and term contracts
Spot contracts are contracts to purchase or sell a commodity at the market 
price prevailing on or around the delivery date when title to the inventory 
is taken. Term contracts are contracts to purchase or sell a commodity at 
regular intervals over an agreed term. Though spot and term contracts may 
have a standard form, there is no offsetting mechanism in place. These 
transactions result in physical delivery with operational and price risk. Spot 
and term contracts typically relate to purchases of crude for a refinery, 
purchases of products for marketing, purchases of third-party natural 
gas, sales of the group’s oil production, sales of the group’s oil products 
and sales of the group’s gas production to third parties. For accounting 
purposes, spot and term sales are included in sales and other operating 
revenues, when title passes. Similarly, spot and term purchases are 
included in purchases for accounting purposes.

Corporate governance Corporate governanceBoard performance report

Dear shareholder,

In my letter to shareholders earlier in this report I have endeavoured to give 
an overview of the challenges which the company has faced in 2011 and 
the work of the board in meeting those challenges. 

In this letter, and in the report which follows, my aim is to give 
shareholders, and indeed all those with whom the company interacts, 
a deeper insight into the evolution of the BP board, the review which it 
has undertaken and the changes that have been made, and which are 
continuing to be made, to govern your company at the highest standard.
BP has a clear system of governance based upon the BP board 

governance principles. This serves BP and its board well. It is vital that the 
system of governance, “what” the board does, evolves with the company 
and with the thinking of those charged with its governance.

The tragic events in the Gulf of Mexico require that the board 
consider how it operates; however the substantial change in directors 
has meant there have been new views on the role of the board. This has 
resulted in the evolution that I have mentioned. In undertaking strong 
governance of the company, I believe that the board should provide 
leadership and challenge, but also support to executive management. In its 
activities this year, the board has strived to achieve this role.

The tasks of the board set out later in this report have not and will 
not change. It was clear though that a board which governs a company of 
the scale and scope of BP needs to have a clear view of its role  
and the steps it can take to support or challenge and the information  
which it needs.

The board is initiating modifications in all of these areas and 

will keep those changes under review. The actions from this work are 
important as we operate a system of governance throughout the company. 
The framework for how the board works is articulated in our board 
governance principles, available on our website at bp.com/governance.

Over this coming year we will maintain focus, discipline and follow 

through at the board as we continue to deal with a volume of issues. 
Looking forward into 2012, one of our aims is to get back into a steady 
rhythm of board meetings. We hope to do this through strengthening our 
forward agenda and board planning processes. We will also maintain our 
focus on the skills and experience of our directors, the composition of our 
board and succession planning.

Diversity within UK boards was a topic of debate in 2011 and 

will remain so going forward. BP is a company with global reach and we 
believe that it is important to have a board that is diverse in the widest 
sense; the company remains committed to meritocracy as well as to 
diversity. As part of the update of our board governance principles we have 
included a policy on board diversity. At the time of writing we have 12.5% 
female representation on the board. Our goal is to increase the number 
of women on the board to three by 2013 and to work towards 25% 
representation by 2015.

In the governance report which follows we have outlined key 

elements of the activities of the board and its committees during the year.

Carl-Henric Svanberg
Chairman

120    BP Annual Report and Form 20-F 2011

How the board works
BP’s governance framework
BP’s system of governance begins with the board and continues into 
our subsidiaries. The governance framework is outlined in the BP board 
governance principles which sets out the role of the board, its processes 
and its relationship with executive management.
The board’s core activities include:
•	 The active consideration of long-term strategy.
•	 The monitoring of executive action and the performance of BP.
•	 Obtaining assurance that the material risks to BP are identified and that 
systems of risk management and control are in place to mitigate such 
risks.

•	 Ongoing board and executive management succession.

In all its work the board sets the ‘tone from the top’ for the organization by 
considering specific issues, including health, safety, the environment and 
BP’s reputation and working with management to set the values of the 
company.

During 2011 the board undertook a review of its corporate 
governance model. A working group consisting of the chairman and three 
non-executive directors (Paul Anderson, Antony Burgmans and Cynthia 
Carroll) examined key aspects of BP’s system of governance, including 
the system of delegation, board processes, information, risk and the tasks 
and role of the committees. During the review, input was sought from 
board members and from executive management, both through board and 
working group discussions and individually through our board evaluation 
process.

The review concluded that BP’s system of governance is robust 

but that further clarity on board processes would help reinforce the 
board’s delegation to the group chief executive and strengthen the board’s 
monitoring and assurance role.

Who’s on the BP board?
The composition of the board and the mix of knowledge, skills and 
experience that our directors bring to the company is a key area of focus 
for the nomination committee. The committee keeps this mix under review 
and regularly maps the skillset of our existing board membership against 
the likely tenure of individual directors. This is viewed against the potential 
demands placed on the board due to developments in our strategy and 
business activities. Further detail of the current skillset of the board and 
the skills/competencies that the nomination committee has prioritized for 
future non-executive director appointments is outlined in the report of the 
nomination committee later in this section.

Full biographies of our board members can be found on our 

website.

2012 AGM and will be available to shareholders who have concerns that 
cannot be addressed through normal channels. He will work closely with 

Corporate governanceAntony Burgmans who, given his length of service on the board, will 
respond to any internal board matters, act as a sounding board for the 
chairman and serve as an intermediary for other directors if necessary.
Sir William stepped down as chairman of the safety, ethics and 

environment assurance committee (SEEAC) and Paul Anderson became its 
chairman from 9 December 2011. 

Ian Davis stepped down as a member of the audit committee on 

3 February 2012 and Frank Bowman joined the Gulf of Mexico committee 
on the same date.

Neither the chairman nor the senior independent director are 

employed as executives of the group. The board maintains a succession 
plan for the chairman and senior independent director, in addition to the 
group chief executive and senior management.

Appointment and tenure
The chairman and our non-executive directors (NEDs) serve on the basis 
of letters of appointment. BP does not place a term limit on director’s 
service as we propose all directors for annual re-election by shareholders (a 
practice we have followed since 2004).

The governance principles require our non-executive directors to be 
independent in character and judgement and free from any business or 
other relationship which could materially interfere with the exercise of their 
judgement. The board has determined that those non-executive directors 
who served during 2011 fulfilled this requirement and were independent.
The board also satisfied itself that there is no compromise to the 
independence of, or existence of conflicts of interest for, those directors 
who serve together as directors on the boards of outside entities or who 
have other appointments in outside entities. These issues are considered 
on a regular basis at board meetings. The nomination committee keeps 
under review the nature of non-executive directors’ other interests to 
ensure that the effectiveness of the board is not compromised. The 

committee may make recommendations to the board if it concludes that a 
director’s other commitments are inconsistent with those required by BP.

Time commitment and outside appointments
Letters of appointment for non-executive directors do not set out a fixed 
time commitment for board duties as we believe that the time required 
by directors may fluctuate depending on demands of the business and 
other events. However, it is expected that directors will allocate sufficient 
time to the company to perform their duties effectively. The chairman’s 
appointment letter sets out the time commitment expected of him.
Following an approach from the Volvo Group, the chairman 

discussed with the board, through the chairman’s committee, whether 
to take an additional post as a part-time non-executive chairman of Volvo. 
During this process, our senior independent director led a discussion of 
non-executive directors without the chairman present to hear their views. 
The board concluded that Mr Svanberg has sufficient time to carry out both 
commitments and supported the chairman taking on this additional role. 
The chairman will step down from his existing non-executive directorship 
at Ericsson before assuming the chairmanship of Volvo in April 2012; he 
also confirmed to the board that he does not intend to seek any additional 
roles outside those at BP and Volvo.

Executive directors are permitted to take up one external board 

appointment, subject to the agreement of the chairman and provided such 
external appointment is reported to the BP board. Fees received for an 
external appointment may be retained by the executive director and are 
reported in the Directors’ remuneration report.

Diversity
BP recognizes the importance of diversity, including gender, at all levels 
of the company as well as the board. The company is committed to 
increasing diversity across our operations and has in place a wide range of 
activities to support the development and promotion of talented individuals, 
including women.

During the year, the board responded to Lord Davies’ report on 

gender diversity and confirmed its goal to increase the number of women 
on the BP board to three by 2013 and work towards the recommendation 
of 25% female representation by 2015. With the appointment of Professor

BP Annual Report and Form 20-F 2011    121

Corporate governanceCorporate governanceDame Ann Dowling, BP currently has two female board members, 
equating to 12.5% of our directors.

The board has agreed a board diversity policy which will be 
included in our board governance principles. The policy states that when 
considering the composition of the board, directors will be mindful of 
diversity, inclusiveness and meritocracy. As part of its workplan for this 
year, the nomination committee will develop and agree a set of measurable 
objectives for implementing this policy and report back on these to 
shareholders.

Induction and board learning
On joining BP non-executive directors are given a tailored induction 
programme. This programme includes one-to-one meetings with senior 
management, our auditors and site visits to our operations. The induction 
will also cover the board committees that a director will join. An example of 
the initial induction programme for one of our recently joined non-executive 
directors is set out below.

Director induction programme

We continue the board’s learning through board and committee events. 
At our May 2011 board meeting in Houston, we ran a day-long event 
to give our non-executive directors an insight into how BP manages 
its learning and capability development, including briefings on seismic 
interpretation, the company’s technical education programme and trading. 
Non-executive directors are expected to attend at least one site visit per 
year. During 2011, such visits included Texas City and Whiting refineries 
with the independent expert, L. Duane Wilson, an offshore visit to the Gulf 
of Mexico, visits to global wells organization leadership teams in the Gulf 
of Mexico and the North America gas business, our business centre in 
Budapest and BP’s offices in Houston and Canary Wharf. During the year 
our chairman visited BP’s operations in Alaska and our oil sands projects in 
Canada.

Board effectiveness
Board evaluation
We undertake an annual review of the board, its committees and individual 
directors. The chairman undertakes the evaluation of individual directors, 
with the chairman’s own performance evaluated by the chairman’s 
committee (led by the senior independent director).

In 2009 and 2010, we undertook an external review of the board’s 

performance. In 2011, we decided to continue external facilitation as a 

122    BP Annual Report and Form 20-F 2011

way of building on the past year’s results and providing a robust, third-
party insight into the board’s effectiveness. To enable continuity and 
comparability of results over the two year period, we used the same 
external facilitator as for the 2010 review.

Evaluation process for 2011
•	 Each director (with the exception of those appointed in 2012) was sent a 

questionnaire and a list of discussion topics.

•	 The facilitator held one-to-one reviews with each participating director, 

using the questionnaire and discussion topics as a starting point.

•	 Each committee held its own review using online questionnaires that 

were developed by us using an externally generated question bank. The 
results from these questionnaires were then discussed with the external 
facilitator by each committee (these are outlined in the reports of our 
committees).

•	 A paper on the key themes and views from the one-to-one reviews and 

the evaluation of the committees were sent to the board to review.

•	 The board held a discussion with the external facilitator to assess these 

views and the issues raised.

•	 The board agreed on actions for the forthcoming year based on this 

discussion.

Key conclusions of the 2011 evaluation
The review concluded the board had operated well in 2011. It had been 
an eventful year and the board continues to deal with events from 
the Gulf of Mexico. There was a strong view that the board had an 
open and transparent style of discussion, with good engagement and 
contribution from all members, particularly around strategic planning and 
risk management. The board also considered that its focus, discipline 
and follow through had strengthened over the year, which was seen as 
important given the events of the previous 18 months and the volume of 
issues dealt with by the board. It hoped to continue this trend in 2012.
The review also found that there was potential for continuous 
improvement in areas such as board materials (including the length of 
papers) and agendas, and that as the board endeavours to move back 
into a ‘steady state’ of operation, it would need to revisit its collective 
expectation around governance processes and style.

Tracking issues from our previous evaluation
Over 2011, the board acted upon the recommendations from the 2010 
board evaluation. The board determined to conduct additional site visits 
and participate in detailed briefings in order to gain further insight into the 
company’s operations and activities – which it achieved through an active 
programme over the year attended by individual or groups of directors. The 
board set up a working group to review and revise the company’s board 
governance principles to ensure that BP’s governance processes were 
effective. The board also reviewed BP’s crisis and continuity plan, including 
specific focus on the process through which board involvement is triggered 
as part of its action to clarify the board’s role in the crisis planning process. 
Finally, the board had extensive engagement with executive management 
in forward-looking strategy discussions and an overview of BP’s risk 
management systems.

Risk management: from operations to the board
One of the board’s tasks is to satisfy itself that the material risks to BP 
are identified and understood and that systems of risk management, 
compliance and control are in place to mitigate such risks. The board, 
through its governance principles, requires the group chief executive to 
operate with a comprehensive system of controls and internal audit to 
identify and manage the risks that are material to BP. Authority for the 
design and implementation of this system of internal control is delegated 
by the board to the group chief executive. Components of our system 
of internal control (which includes the risk management system) are 
management systems, organizational structures, processes, standards and 
behaviours employed to conduct the business of BP.

 Results in risk data

Risk management in BP is a ‘top-down’ and ‘bottom-up’ process. The 
‘bottom-up’ process starts at the day-to-day level with businesses and 
functions identifying and managing their risks using existing company 
standards and practices, e.g. OMS. The most significant risks are organized 
into common categories – strategic risks, safety and operational risks and 
compliance and controls risks – so they can be reported up the line in a 
standardized form.

During the year a review of BP’s risk management system was 

initiated which has built on our current system of risk management. Using 
the findings of this review, BP has started to implement enhancements 
to drive consistency and clarity in how risks are reported and understood 
in all levels of our organization from operations to the board. See 
Our management of risk on page 42 for further discussion of the risk 
management system and 2011 review.

Within BP’s risk management system, functions set standards, 

provide guidance and provide a view of group risks in their functional area 
of expertise, independent of line management. Certain functions also 
deliver assurance that the activities to manage the risks are working as 
intended in the businesses.

Group risks are allocated to one of the committees established 

by the group chief executive for management and monitoring. 
These executive level committees are sub-committees of our senior 
management team and their role includes setting policy, making decisions 
and overseeing the management of risks and performance. The executive 
committees are:
•	 Group operations risk committee (GORC) for risks of a safety, 

environment or operations nature.

•	 Group financial risk committee (GFRC) for finance and trading risks.
•	 Group disclosure committee (GDC) for financial reporting risks.
•	 Group people committee (GPC) for people risks.
•	 Resource commitments meeting (RCM) for risks related to investment 

decisions.

At the group level, risk is examined by the board to apply a ‘top-down’ 
perspective. The group risks identified as requiring particular oversight in 
the coming year are selected for discussion with the board. These are then 
allocated for review by the board or one of its committees. A common 
agenda for the review is established to enable the board or committee to 
discuss risk in a consistent manner with executive management.

The board examines group risks both on a periodic basis and as part 

of its review of the annual plan. The board also conducts an annual review 
of the risk management and internal control systems as required by the UK 
Corporate Governance Code. During the year there is flexibility to change 
which risks have been identified as requiring particular oversight and which 
have been allocated to the board and its committees, in the event there are 
any changes to the internal or external environments or events arising.

Following its review of the 2012 annual plan, the risks described 

above have been allocated for review by the board and its committees as 
follows:
•	 The board has been allocated several strategic and safety and operational 
group risks, including risks associated with the macroeconomic outlook, 
the delivery of the 10-point plan, the group’s exposure to Russia, crisis 
management, reputational impact and the recruitment and development 
of staff.

•	 The audit committee has been allocated a number of compliance and 

control and safety and operational risks, including risks associated with 
treasury and trading activities, compliance with applicable laws and 
regulations and security threats against our digital infrastructure.
•	 The safety, ethics and environment assurance committee has been 
allocated several safety and operational and strategic risks, including 
risks associated with conducting our operations through joint ventures 
or associates and through contracting and sub-contracting arrangements 
where BP may not have full operational control. Other safety and 
operational risks the committee have been allocated include the health, 
safety and environmental risks of incidents associated with the drilling of 
wells, operation of facilities and transportation of hydrocarbons.

•	 The Gulf of Mexico committee has been allocated a number of strategic 
risks, including risks associated with the extent and timing of costs and 
liabilities relating to the incident and the possible impact on our licence 
to operate.

Board activities during 2011
2011 was another active year for the board, which met 15 times. The 
board’s focus remained on the incident in the Gulf of Mexico – both to 
understand what happened and how the company can apply the lessons 
learned. Within the board and its committees, debate and assurance 
has been ongoing with management on key aspects such as the impact 
on the group’s reputation, accounting treatment and provisioning, 
implementation of the recommendations of the Bly Report and the legal 
and communication strategy for litigation arising from the incident. The 
challenge has remained for the board to ensure that it devoted enough 
time to the ongoing business of the company whilst holding these 
important discussions. Periodic meetings throughout the year of the non-
executive directors comprising the chairman’s committee, together with 
liaison between the chairman and the chairs of the board committees, 
have assisted in managing this challenge. Areas discussed by the board 
included the following:

Strategy
The board is engaged at the early stages of discussion on strategy and the 
annual plan in order to provide constructive challenge. During the year two 
day-long meetings were held for strategic discussions. After the February 
2011 update to the market the board continued to develop the company’s 
strategy with respect to milestones and deliverables, resulting in a further 
market update in October on the company’s ”10-point-plan”. Over the 
year, the board considered key strategic elements, including biofuels, 
Canadian heavy oil and the company’s disposal programme. The board also 
spent considerable time discussing strategic opportunities and implications 
of the strategic alliance that had been proposed with Rosneft and the new 
relationship with Reliance.

BP Annual Report and Form 20-F 2011    123

Corporate governanceCorporate governanceAssurance
The board undertook a number of activities as part of its assurance 
role, including assessing the effectiveness of the company’s system of 
internal controls and risk management. The group’s financial performance 
was considered, as was a review of BP’s technology function and the 
performance and role of the technology group within the outlook for energy 
demand and supply.

The board received an overview of BP’s activities in the US and 
received several updates during the year on legal issues, in particular on 
litigation and enquiries resulting from events in the Gulf of Mexico. The 
board discussed the UK Bribery Act and the steps the company was taking 
to comply with the Act; as a result of this discussion the board endorsed 
the updated anti-bribery policy outlined in BP’s code of conduct.

L. Duane Wilson, the independent expert appointed by the board 
to provide an objective assessment of BP’s progress in implementing the 
recommendations of the BP US Refineries Independent Review Panel, 
presented his fourth annual report to the board where he assessed BP’s 
progress against the Panel’s 10 recommendations. Further details of 
Mr Wilson’s work are outlined in the report of the SEEAC and his report is 
published on BP’s website at bp.com/independentexpert.

Risk
The board discussed the progress and outcome of the review of BP’s 
risk management system over the year. The outcome of the review has 
resulted in clearer and more consistent reporting, definitions and templates 
for BP’s risk management activities, as well as greater alignment of these 
risk management activities with existing BP business processes.

The board and its monitoring committees (audit, SEEAC and Gulf 
of Mexico) monitored the group risks which had been allocated following 
the board’s review of the annual plan at the end of 2010. The annual plan 
and the group strategy are central to our risk management programme as 
they provide a framework for the board to consider significant risks and 
manage the group’s overall risk exposure as well as underpin the model 
of delegation and assurance for the board in its oversight of executive 
management and other activities.

Reputation
The board considers reputation from two perspectives – the reputational 
risks to the group and the processes the company has in place to manage 
these risks. During the year, the board reviewed external reputation data 
which looked at BP’s reputation in the UK and US. It also discussed the 
group’s communications strategy and its reputation management plan.

BP’s group-wide renewed values were launched in 2011 as part 

of a programme of change called ‘We are BP’, by which the renewed 
values will be reflected in how employees’ performance is assessed and 
rewarded. The renewed values were also embedded within the updated 
code of conduct.

Governance
As described above, over the year the board reviewed its system of board 
governance and established a working group to assist in this process. The 
main outcomes of the review were strengthened board processes around 
information, risk and revisiting the role and tasks of the board and its 
committees.

The board seeks to understand the views of its shareholders, and 

feedback from investors is given to the board – either directly following 
meetings with the chairman or other board members or indirectly through 
an annual investor audit undertaken by a third party. Following our AGM in 
April 2011, the board examined the voting results for each resolution and 
considered the comments received from institutional investors to explain 
their voting position.

Shareholder engagement
The company continued its open dialogue with shareholders. Our 
executive directors and members of our executive management team held 
investor meetings following our strategy and financial results. We also held 
meetings on operating and non-financial issues, including presentations 
on BP’s Energy Outlook 2030, an update on BP’s activities in Canadian 
oil sands, our Alternative Energy and Refining and Marketing businesses 
and BP’s environmental and social requirements for new projects. These 
events were intended to give shareholders a wider perspective on the 
company’s thinking behind its strategy and an understanding of the 
processes and standards we use to underpin our operations.

The chairman, senior independent director and chair of our 

remuneration committee held a number of one-to-one meetings with 
institutional investors to discuss strategy, the board’s view on the company’s 
performance and governance and our remuneration structure. In addition 
the chairman, with two members of our senior executive team, spoke at 
group investor events in the US and UK to outline the company’s progress 
on the Bly Report recommendations, the remit and work of the safety and 
operational risk function and the work of the board. In March 2011 we held 
our annual investor event with our chairman and the chairs of our board 
committees. We continue to receive positive feedback on this event and find 
it an effective way for our largest shareholders to hear about the work of our 
board and our committees, and for our non-executive directors to engage in 
dialogue with investors. We intend to hold a similar event in March 2012.
During the year we focused on enhancing communication with 
our private shareholders, including a revision of dividend materials and 
the shareholder information pages of our website. We continued our ‘lost 
shareholder’ programme which returns shares and unclaimed dividends to 
shareholders who have failed to keep their contact details up to date.
Materials from our investor presentations, including information on the 
work of our board and its committees can be downloaded from the 
investors page of our website.

 * Attendance for audit committee and SEEAC includes a joint meeting between the two committees.

NB: The chairman also attends meetings of the remuneration and Gulf of Mexico committees.

AGM
We continue to have a well-attended annual general meeting, usually 
attracting over a thousand people. Our shareholder base is geographically 
diverse and we offer a webcast and advance voting to make our meeting 
accessible to those who cannot attend in person.

The voting levels for our 2011 AGM saw a moderate increase over 
2010 levels to 60.6% (59.6% in 2010). Viewers of our 2011 AGM webcast 
increased by fivefold over the previous year. We make our webcast, 
speeches and presentations from the AGM available on our website after 
the meeting, together with the outcome of voting on each resolution.

International advisory board
In 2009, BP formed an international advisory board (IAB) whose purpose is 
to advise the chairman, group chief executive and our board on geopolitical 
and strategic issues relating to the company. This group has an advisory 
role and meets twice a year – although its members are on hand to provide 
advice and counsel to the company when needed.

The IAB is chaired by our previous chairman, Peter Sutherland. Its 

membership in 2011 included Kofi Annan, Lord Patten of Barnes, Josh 
Bolten, President Romano Prodi, Dr Ernesto Zedillo and Dr Javier Solana. 
Our chairman and chief executive attend meetings of the IAB. Issues 
discussed during the year included developments in the eurozone, events 
in the Middle East and the world energy outlook.

UK Corporate Governance Code compliance
BP complied throughout 2011 with the provisions of the UK Corporate 
Governance Code, except in the following aspects:
B.3.2 

 Letters of appointment do not set out fixed time commitments 
since the schedule of board and committee meetings is subject 
to change according to the demands of the business and 
other events. All directors are expected to demonstrate their 
commitment to the work of the board on an ongoing basis. This 
is reviewed by the nomination committee in recommending 
candidates for annual re-election.
 The remuneration of the chairman is not set by the remuneration 
committee. Instead the chairman’s remuneration is reviewed by 
the remuneration committee which makes a recommendation 
to the board as a whole for final approval, within the limits set 
by shareholders. We believe this wider process lets all board 
members discuss and approve the chairman’s remuneration 
(rather than solely the members of the remuneration committee).

Corporate governanceCorporate governanceCommittee reports

Audit committee
Chairman’s introduction
In the first quarter of the year the committee, under Douglas Flint’s 
chairmanship, continued to spend considerable time reviewing and 
challenging BP’s assessment of its financial responsibilities relating to the 
tragic incident in the Gulf of Mexico in April 2010. This task has remained a 
key area of focus under my chairmanship during the remainder of the year. 
We have continued to seek assurance that where liabilities are estimable, 
they are fully provided for, and where uncertainty is too great to support 
a provision that appropriate disclosure is made. Some greater clarity 
developed during the year as experience was gained about the operation 
of the Deepwater Horizon Oil Spill Trust fund, and as settlements were 
reached with two of the partners in the Macondo well and two of the 
contractors involved. However, as reported elsewhere in this document, 
major uncertainty remains in respect of litigation, potential fines and 
penalties and other matters which will require significant attention from the 
audit committee for the foreseeable future. The committee has therefore 
taken care to preserve its regular agenda content so as to continue fulfilling 
its remit to the board with respect to monitoring risk management systems 
and internal controls and financial reporting.

Amongst other topics, we have reviewed controls in trading, debt 
and liquidity management and the company’s response to the UK Bribery 
Act. During the course of the year, I have also participated in the group 
chief executive’s audit forum and the group financial risk committee 
(GFRC). In preparation for audit committee meetings, I have met regularly 
with the chief financial officer, general auditor and the lead partner of the 
external auditors. I also spent time with the leadership team of the internal 
audit function.

I valued the time I took to visit one of the company’s largest data 

centres in London, its European business service centre in Budapest, and 
the trading floors in Houston and London. Such visits and interaction with 
staff at all levels of the organization enhance both our understanding of 
the company’s activities and our assurance over the way they are being 
managed.

Although we lost Douglas Flint from the committee when he 

stepped down from the board, I am delighted that Andrew Shilston has 
now joined us. Andrew’s experience as the CFO at Rolls Royce, and his 
previous background in the energy business, complements the skills 
already present in the committee’s membership. I believe we have a 
very good mix of commercial, financial and audit expertise to address 
the complex accounting, audit and risk issues which the committee 
monitors. I would also like to thank Ian Davis for his contribution to the 
audit committee over the last two years. Ian is now stepping down from 
the committee in anticipation of a period of heavier workload related to the 
Gulf of Mexico committee.

Our report below seeks to highlight the key activities undertaken 
in 2011 and provide some insight into the outcomes of the committee’s 
work. I believe 2012 will be equally intense but the committee is well 
equipped to address the tasks it faces.

expertise appropriate to fulfil the committee’s duties.

126    BP Annual Report and Form 20-F 2011

Brendan Nelson became chair of the audit committee upon the retirement 
of Douglas Flint from the board in April 2011. Mr Nelson, who was formerly 
vice chairman of KPMG, is chairman of the Group Audit Committee of The 
Royal Bank of Scotland Group plc, a member of the Financial Reporting 
Review Panel, Vice President of the Institute of Chartered Accountants 
of Scotland and a director of the Financial Skills Partnership. The board is 
satisfied that Mr Nelson, in succession to Mr Flint, is the audit committee 
member with recent and relevant financial experience as outlined in the  
UK Corporate Governance Code. It considers that the committee as a 
whole has an appropriate and experienced blend of commercial, financial 
and audit expertise to assess the issues it is required to address. The board 
also determined that the audit committee meets the independence criteria 
provisions of Rule 10A-3 of the US Securities Exchange Act of 1934 and 
that Mr Nelson may be regarded as an audit committee financial expert as 
defined in Item 16A of Form 20-F.

Committee role and structure
The role and responsibilities of the audit committee are set out in the 
appendix of BP’s board governance principles which is available on our 
website. We keep these under review and test their effectiveness in 
our annual evaluation of the audit committee. In addition, the chairs and 
secretaries of the audit and safety, ethics and environment assurance 
committees have worked together to ensure their respective agendas 
neither duplicate nor omit coverage of key risk areas.

The committee met 11 times over the past year including one joint 

meeting with the safety, ethics and environment assurance committee 
(SEEAC). This joint meeting reviews the general auditor’s report on internal 
control and risk management systems for the year in preparation for the 
board’s report to shareholders in the annual report. It also reviews the 
general auditor’s audit programme for the year ahead to ensure both 
committees endorse the coverage.

Each audit committee meeting is attended by the group chief 

financial officer, the group controller, the general auditor (head of internal 
audit) and the chief accounting officer. The lead partner of our external 
auditors (Ernst & Young) is also present.

The committee also holds separate private sessions during the 

year with the external auditor and the general auditor – these sessions are 
without the presence of executive management.

The board is kept updated and informed of the audit committee’s 

activities and any issues arising through verbal reports at its meetings from 
the committee chair and the circulation of the committee’s minutes.

Audit committee processes
Information and advice
Information and reports for the committee are received directly from 
accountable functional and business managers and from relevant external 
sources. In addition, like our board and other committees, the audit 
committee can access independent advice and counsel when needed 
on an unrestricted basis. During 2011, external specialist legal advice in 
relation to corporate reporting was provided to the committee by Sullivan & 
Cromwell LLP. As part of its annual evaluation, the committee reviews the 
adequacy of reliable and timely information from management that enables 
it to fulfil its responsibilities. The 2011 evaluation indicated that members 
recognized the openness and transparent nature of the materials and 
presentations provided by management.

Training and visits
In continuing to respond to the consequences of the Gulf of Mexico oil 
spill, the committee placed emphasis on receiving appropriate briefings on 
the relevant applications of accounting policy, particularly provisioning and 
related disclosure. The committee received regular technical updates from 
the chief accounting officer on developments in financial reporting and an 
annual briefing on oil and gas reserves disclosures. In addition the external 
auditors provided insight and commentary on international accounting 
policy developments.

Induction programmes are provided for new members and are 

tailored around their roles on the audit committee. During 2011 Brendan 
Nelson and Phuthuma Nhleko completed their audit committee induction 
programmes. This included sessions on tax, trading operations, accounting, 

Corporate governancefinancial reporting and controls and the structure of BP’s finance function. 
Individual private sessions with the external and internal auditors were also 
provided. During 2012 we will undertake an audit committee induction for 
Andrew Shilston.

When the board visited Houston in May, audit committee members 

took the opportunity to visit the computing facility and the trading floor 
at the Westlake complex. During the May trip, two members of the 
committee, including the chairman, also visited the Atlantis offshore 
platform in the Gulf of Mexico. In July the committee visited the 
company’s data centre in London to review IT service and security matters. 
Earlier in the year Mr Nelson accompanied SEEAC members on a visit to 
the Whiting refinery where they were briefed on the progress of the major 
modernization project. These visits enable the committee to see first-
hand examples of risk management and to address questions directly to 
employees on site.

2011 Audit committee activities
Gulf of Mexico
The responsibilities of the board’s monitoring committees in reviewing 
the company’s response to the Gulf of Mexico incident have been 
carefully delineated. Whilst the Gulf of Mexico committee has considered 
the ongoing work of the Gulf Coast Restoration Organization (GCRO) 
and litigation matters, and the SEEAC has reviewed the company’s 
implementation of the recommendations of the Bly Report, the audit 
committee’s focus has been on financial reporting and controls. The 
committee has reviewed each quarter the provisions and contingencies 
related to the incident and their disclosure. It has also received a report 
from the group controller on the status of financial controls in the GCRO.

Financial reporting
The group’s quarterly financial reports, the BP Annual Report and 
Form 20-F and the BP Summary Review were reviewed by the committee 
before recommending their publication to the board. In undertaking 
this review, the committee discussed with management how they had 
applied critical accounting policies and judgements to these documents, 
including key assumptions regarding provisions for litigation, environmental 
remediation and decommissioning. The committee also reviewed the 
impairment testing process and the pricing assumptions that were utilized. 
In considering the robustness of the valuations the committee also 
referred to analysis undertaken by the external auditors. This year, with a 
number of assets held for sale, the committee was appropriately engaged 
in reviewing their accounting treatments. Further details on impairment 
reviews are included in the Financial statements – Note 5. The committee 
also reviewed the company’s methodology underpinning its disclosures 
relating to oil and gas reserves.

Monitoring business risk
As discussed elsewhere in this annual report, the board periodically 
reviews the company’s group risks and allocates monitoring of their 
management and/or mitigation to itself or its committees. Within the 
audit committee’s area of monitoring in 2011 were liquidity management, 
trading risk and corruption risk. During the year, the committee also 
undertook functional reviews of information technology and services, 
integrated supply and trading, business service centres and the governance 
and control of major project investment. Each year the committee also 
reviews risk, governance and the control environment relating to TNK-BP.

Reports on the work of the group financial risk committee – the 
executive-level committee that provides assurance on the management 
of BP’s financial risk – were provided during the year by the chief financial 
officer.

Internal control, audit and risk management
The forward agenda for the audit committee contains standing items 
on internal control – these include quarterly reports of internal audit 
findings, internal control deficiencies in financial reporting, and an annual 
assessment of BP’s enterprise level controls. The committee also received 
a joint report from the group controller and chief information officer on 
access controls and segregation of duties.

An important input into the board’s review of the company’s risk 
management and internal control systems is the annual joint meeting 
between the audit committee and the SEEAC. This takes place at the 
start of each year to review the general auditor’s report on internal 
control and risk management systems for the previous year. The general 
auditor reviews his team’s findings and management’s actions to 
remedy significant issues identified in that work. His report also included 
information on the results of audit work undertaken by the safety and 
operational risk audit team and reviews by the group’s finance control 
team. As noted earlier, this joint meeting also reviews the coming year’s 
forward programme of audit work.

External auditors
In 2011 the committee held two scheduled meetings with the external 
auditors without management being present. These sessions provided 
the opportunity for direct feedback and dialogue between the committee 
and the auditors. In addition, the chair of the audit committee met privately 
with the external auditors before each audit committee.

Performance of the external auditors is evaluated by the audit 
committee each year. This year the committee put particular focus on 
assessing audit quality against a set of agreed key performance indicators. 
The company has also developed an auditor assessment tool which will 
be completed on an annual basis and apply five main performance criteria 
– robustness of the audit process, independence and objectivity, quality of 
delivery, quality of people and service, and value-added advice.

The committee reviews the composition of the audit team annually 

and meets the relevant partners when undertaking business or function 
reviews. Additionally, the committee has the opportunity to assess specific 
technical capabilities in the audit firm when addressing specialist topics, 
such as environmental provisioning and impairment testing.

We maintain auditor independence through limiting non-audit 

services to tax and audit-related work that fall within defined categories. 
For a list of those categories, the process by which non-audit work is 
approved when the audit committee concludes that it is in the interests 
of the company to purchase non-audit work from the external auditor 
(rather than another supplier), see the section Principal accountants’ fees 
and services on page 136. A new lead audit partner is appointed every 
five years and other senior audit staff are rotated every seven years. No 
partners or senior staff from Ernst & Young who are connected with the 
BP audit may transfer to the group.

Non-audit work by Ernst & Young is subject to the audit 
committee’s pre-approval policy. Non-audit work undertaken by Ernst 
& Young and by other accountancy firms is regularly monitored by the 
committee.

Fees paid to the external auditor for the year were $55 million, of 
which 20% was for non-audit work (see Financial statements – Note 16). 
Non-audit fees increased from $8 million in 2010 to $11 million in 2011 due 
to additional work undertaken in providing services related to corporate 
finance transactions. This increase resulted from Ernst & Young’s 
engagement to carry out financial due diligence in connection with actual 
and proposed sales of assets in North America.

The audit committee considers both the fee structure and the audit 
engagement terms and monitors progress during the year. In October the 
committee reviewed with management the criteria which would trigger 
tendering the audit. The criteria considered were independence, quality 
of service, audit quality, cost/value for money and regulatory changes. 
The committee and management believe that assessed against each 
of these criteria there is no case for recommending going to tender this 
year. Nonetheless, preparatory work has been undertaken to understand 
the potential for other audit firms to participate in a tender should this be 
indicated at a future date. The committee has recommended to the board 
that the re-appointment of Ernst & Young as the company’s external 
auditors be proposed to shareholders at the 2012 AGM.

Internal audit
The committee receives quarterly reports from the general auditor which 
enable the committee to monitor the progress of the internal audit against 
its planned schedule of audits as well as to track key findings and any 
material actions that are overdue or have been rescheduled. In reviewing 

BP Annual Report and Form 20-F 2011    127

Corporate governanceCorporate governancethe audit programme proposed each year, the committee looks at 
whether it believes key risks facing the company have been appropriately 
addressed. The programme for 2011 was approved by the committee in 
January 2011.
The general auditor met privately with the committee once during the year, 
without the presence of executive management or the external auditors. 
This is complemented by regular meetings with the committee chair 
between meetings.

The committee reviewed with the general auditor the number and 

expertise of his team’s staff resources. The internal audit function provides 
a source of skilled staff to many parts of the company and to maintain its 
resources the general auditor recruits from both inside the company – to 
bring in deep business expertise into the team – and externally – to bring 
professional auditing skills. The committee has sought assurance that 
these resources are sufficient to fulfil the function’s role, and the general 
auditor has undertaken benchmarking work with other major companies in 
the industry. In addition, an external review on internal audit effectiveness 
has been undertaken in 2012. This review concluded that BP had an 
effective internal audit function that compared favourably with other 
complex and industry equivalents.

During 2011 the committee was satisfied that internal audit had 

the appropriate access it required to information and that management had 
committed to the provision of that information and had responded to the 
results of audit findings in a timely manner.

Other activities
The committee monitors fraud and misconduct through quarterly updates 
from the general auditor and any non-compliance with the BP code of 
conduct through quarterly reports by the group ethics and compliance 
officer. Actions arising are monitored to close out. The annual certification 
report of compliance with the code of conduct, which is signed by the 
group chief executive, is also reviewed by the committee.

The company’s employee concerns programme OpenTalk has 
been adopted by the committee for whistle-blower monitoring, and all 
financial issues that have been flagged are reviewed by the committee. 
The quarterly reports the committee receives track trends in both the case 
type and time taken to close out queries and reports.

Committee evaluation
Each year the audit committee examines its performance and 
effectiveness, and ensures that its tasks and processes remain 
appropriate. In 2011, the committee used an internally-designed 
questionnaire administered by external consultants. The same question 
set was used as in 2010 so that any trends could be identified. Key areas 
covered included the clarity of its role and responsibilities, the balance 
of skills among its members and the effectiveness of reporting its work 
to the board. Specific areas identified for focus in 2012 included trading, 
provisioning and the effectiveness of internal audit. Regarding process, 
members noted that fulfilling the committee’s remit had led to lengthy 
meetings, but at the same time they recognized a wish to extend deep 
dives into specific topics. The committee noted that, in areas of common 
interest such as compliance and ethics, it needed to continue to work 
closely with the SEEAC. It also commented on the need for pre-read 
papers to be well focused to ensure best use of agenda time. Overall the 
committee considered it had the right composition in terms of expertise 
and had effectively undertaken its activities and reported them to the board 
during the year.

Safety, ethics and environment assurance committee 
(SEEAC)
Chairman’s introduction
Whilst the Gulf of Mexico committee, as reported elsewhere in this 
document, has focused its work on the company’s restoration activities 
in the Gulf area and on oversight of ongoing litigation, the SEEAC spent 
considerable time over the past year monitoring the group’s response to 
the 26 recommendations that were made in BP’s investigation report (the 
Bly Report) into the tragic incident in April 2010. Our role has been to seek 
assurance on behalf of the board that each of those 26 recommendations 

128    BP Annual Report and Form 20-F 2011

is being pursued globally with pace and commitment. We have received 
progress reports at each of our meetings and made visits to meet key 
members of the teams in the exploration and production and S&OR 
organizations that are leading these changes. This included visiting an 
offshore platform to get closer to the front line, two in-depth discussions 
with managers in the Houston office and participating in management’s 
wells inspection programme. We have put fresh emphasis on getting a 
deeper perspective into the organization. In part we have achieved this 
through individual committee members undertaking visits and meeting 
staff outside the boardroom environment and then reporting back to the 
committee at the first opportunity. We believe this approach both deepens 
our collective understanding of risk and of management’s controls, and 
enables us to make more informed, and hence more valuable, challenges.
We have endeavoured to follow this approach to all of our work undertaken 
throughout 2011. As always, for a committee reviewing management’s 
assessment and mitigation of non-financial risk, this work has extended 
to a wide range of topics. The report below provides more detail but we 
would highlight our reviews of risks and risk management in pipelines, 
shipping and drilling. We have also taken a deeper look at risks in our 
petrochemicals business, including a visit by three members of the 
committee to the company’s paraxylene manufacturing facility in Texas.
We have continued to be very well served by L. Duane Wilson’s 

independent perspective of the company’s response to the ‘Baker 
Panel’ recommendations following the fire and explosion at the Texas 
City refinery in 2005. We will shortly be appointing a highly experienced 
individual to report independently to SEEAC on the implementation of the 
Bly Report recommendations.

Overall this has been a year of significant change which will take 
time to fully embed but we believe we have observed real and enduring 
progress.

In February 2012 we welcomed to the committee Professor Dame 

Ann Dowling who brings deep experience in technology and engineering.

We concluded during the year it would be appropriate for the 

SEEAC chairmanship to transfer to Paul Anderson once the restructuring 
and reorganization within the company was largely established. This 
introduction to the committee’s report is therefore written by both of 
us. We share the same commitment to monitor closely, and provide 
constructive challenge to, management in its drive for safe and reliable 
operations at all times. We believe that the extensive breadth and depth of 
committee members’ experience will serve us well in the endeavour which 
is so central for a company whose business encompasses the production 
and distribution of hazardous materials.

Committee role and structure
The role of the SEEAC is to look at the processes adopted by BP’s 
executive management to identify and mitigate significant non-
financial risk, including monitoring process safety management, and 
receive assurance that they are appropriate in design and effective in 
implementation.

The committee met nine times in 2011 including a joint meeting 

with the audit committee at which the general auditor’s report on internal 
control and risk management systems for the year was reviewed in 
preparation for the board’s report to shareholders in the annual report. In 
that joint meeting the committees reviewed the internal auditor’s audit 
programme for the year ahead to ensure both committees endorsed the 
coverage. SEEAC also reviewed the planned work of the S&OR audit 
function and noted an enhanced focus on integrating audit work across the 
company. The SEEAC and audit committee worked together, through their 

Corporate governancechairs and secretaries, to ensure that the agendas did not overlap or omit 
coverage of any key risks during the year.

In addition to the committee membership, each SEEAC meeting 
was attended by the group chief executive, the executive vice president 
for safety and operational risk, the general auditor and the external auditors. 
The general counsel also attended most meetings. The committee held 
private sessions for the committee members only (without the presence 
of executive management) at the conclusion of its meetings to discuss 
any issues arising and the quality of the meeting. Between meetings, 
committee members took opportunities to visit company sites and 
received informal briefings through the committee chair, the secretary, 
the external auditor’s lead partner, the general auditor and executive 
management.

SEEAC processes
Information and advice
The committee receives specific reports from the business segments 
but also receives cross-business information from the functions. These 
include but are not limited to the safety and operational risk function, 
internal audit, group ethics and compliance and group security. During the 
year, the main external input into the committee has been from L. Duane 
Wilson, the independent expert (for further information, see the section 
on independent expert below). As for the board and other committees, 
SEEAC can access any other independent advice and counsel if it requires, 
on an unrestricted basis.

Training and visits
The committee extended its coverage and number of visits this year by 
encouraging members to participate individually, or in groups, and report 
back to the next full meeting. Members have also presented at staff 
training events, such as the operations academy at MIT in Boston. A key 
area of focus has been following up on the implementation of the Bly 
Report’s 26 recommendations and on the progress of the new S&OR 
function. In March the chairman and secretary visited Houston to discuss 
how S&OR management was being embedded in the upstream production 
and development divisions and committee members made a further 
visit to Houston in January 2012. In 2011, a committee member also 
participated in an S&OR leadership event in London. Another committee 
member accompanied the executive vice president for developments on 
two inspection visits to oil and gas wells leadership teams. In May the 
committee travelled offshore to the Atlantis platform in the deepwater Gulf 
of Mexico, and also visited the upstream learning centre in Houston to see 
the capability development activity being undertaken and its global reach.

Considerable focus also continues to be placed on the downstream 

and on the company’s response to the BP US Refineries Independent 
Safety Review Panel recommendations. In March two members of the 
committee visited the Whiting refinery, accompanied by the independent 
expert, Mr Wilson, to review progress in risk management systems 
and OMS implementation. In January 2012 members of the committee 
revisited Texas City refinery, again accompanied by Mr Wilson. This 
followed previous committee visits in March 2010, April 2008 and 
September 2007. During this visit, committee members also visited 
the nearby petrochemicals facility to follow up on presentations it had 
received in May and October and to gain plant level experience, as well 
as to observe the extent to which the BP US Refineries Independent 
Safety Review Panel recommendations had been implemented in the 
petrochemicals context.

In addition to the extensive learning experiences provided by these 

visits and meetings with executive management, induction programmes 
are organized for new members of SEEAC. Frank Bowman, who joined 
the committee in November 2010, completed his induction programme 
in 2011.

environmental and regulatory compliance and audit findings. Operational 
risk and performance forms a large part of the committee’s agenda. 
In 2011, the committee put particular focus on gaining assurance that 
the new S&OR organization was developing as envisaged. The S&OR 
function has intervention rights in all aspects of the group’s technical 
and operational activities, including key investment decisions and the 
committee sought evidence that this was working in practice. The 
committee’s visits, as mentioned above, provided opportunities to discuss 
with local staff the interaction between line managers and embedded 
S&OR staff, and where change had occurred as a result. The committee 
was satisfied with the progress being made but will continue to monitor 
this in 2012 along with the enhancement of standard practices and 
processes within OMS.

Monitoring the company’s progress in implementing the 26 
recommendations in the Bly Report is a key task for the committee 
and it received regular updates, including written reports from the 
executive vice president for developments, at five of its 2011 meetings. 
The BP board has identified an independent expert to provide further 
oversight and assurance regarding the implementation of the Bly Report 
recommendations. The engagement of the independent expert is expected 
to commence in the latter half of May 2012. The independent expert will 
report directly to the board. He will track BP’s progress in implementing 
the 26 recommendations from the company’s internal investigation of the 
Deepwater Horizon oil spill and will independently assess the safety, health 
and environmental work of global drilling operations. He will give regular 
updates directly to the SEEAC.

During the year the committee received specific reports on the 
company’s management of risks in shipping, wells and pipelines. The 
potential environmental consequences of loss of containment in these 
activities gave particular focus to the approaches to risk management 
employed. These included design, such as double bottomed hulls 
in tankers, and training, such as drilling simulators and naval cadet 
training programmes. The committee noted that all new projects in 
environmentally sensitive areas are submitted to the requirements of the 
company’s environmental and social review process.

When a fatality in the workforce occurs the committee reviews the 

incident in depth before reporting back to the board. The committee also 
reviews specific incidents to understand root causes and actions being 
taken to prevent recurrence. There has been a particular focus on ensuring 
lessons learned are communicated widely across the company and not just 
within the business segment in which the incident occurred.

Independent expert
Since L. Duane Wilson’s appointment by the board in 2007 as an 
independent expert to provide an objective assessment of BP’s progress in 
implementing the recommendations of the BP US Refineries Independent 
Review Panel, he has presented to the committee at least four times 
a year in person. His role has been to assist the company in improving 
process safety performance at BP’s five US refineries. Annually the 
committee approves his work plan for the year ahead and receives a full 
written report which is made public on the company’s website. In his last 
verbal report Mr Wilson advised that he had observed continued progress 
in process safety performance at each visit he has made to the five 
refineries. He also discussed work remaining to be completed and areas 
requiring special emphasis. As process safety performance has reached 
higher levels in recent years, he noted that the rate of change has naturally 
slowed, but site metrics continued to demonstrate improvements. 
Mr Wilson also noted that some aspects of implementing the Panel’s 
10 recommendations require ongoing activity and hence could never be 
complete, but he considers the company to have appropriate systems 
and processes to continue its work towards process safety leadership. 
Mr Wilson’s reports are published in full and available on our website at 
bp.com/independentexpert.

2011 SEEAC activities
Safety, operations and environment
The committee receives regular reports from the S&OR function, including 
quarterly reports prepared for executive management on the group’s 
health, safety and environmental performance and operational integrity. 
These include quarter-by-quarter measures of personal and process safety, 

Regional and functional reports
Each year the committee receives a report on the progress made in HSE 
at TNK-BP, noting however that formal oversight of HSE performance and 
policies is exercised by TNK-BP’s own HSE committee. It was reported 
that, whilst significant areas for improvement remained, TNK-BP had 

BP Annual Report and Form 20-F 2011    129

Corporate governanceCorporate governancecontinued to make progress in addressing the main safety, ethical and 
environmental challenges confronting it since it was formed in 2003. The 
committee will continue to monitor progress regularly.

The committee continued to receive reports on the joint venture 

operations in Iraq, and in particular was briefed by the company’s head of 
security on the risks and management of security in Iraq. As mentioned 
above, the committee reviewed the company’s shipping activities in 2011 
and was briefed on the function’s response to the threat of piracy in the 
waters off the Somali coast.

The committee also examined quarterly audit reports from BP’s 
internal audit and safety and operational risk functions which highlighted 
key findings and material actions arising from audits which had taken 
place at segment, functional and regional levels and tracked their close 
out. During the year the committee also received written reports from the 
group ethics and compliance officer.

Activities from the executive-level group operations risk committee 

(GORC) are reported to the SEEAC by the group chief executive and 
executive vice president S&OR at each meeting. Improved co-ordination 
of agenda planning was achieved to facilitate executive management level 
review of key risk topics prior to board level review at SEEAC. The SEEAC 
also received regular updates on the company’s interaction with regulatory 
agencies.

Committee evaluation
For its 2011 evaluation, the SEEAC again used a questionnaire 
administered by external consultants to examine the committee’s 
performance and effectiveness. The committee responded to the same 
questions as used in 2010 so that any change trends could be discerned. 
The topics covered included the balance of skills and experience among its 
membership, quality and timeliness of information the committee receives, 
the level of challenge between committee members and management and 
how well the committee communicates its activities and findings to the 
board.

In 2010 the committee had concluded that it should increase its site 

visits and training. In 2011, as reported above, the committee believed it 
had increased these activities significantly and agreed it should continue to 
do so in 2012. It also noted that given its broad remit across non-financial 
risk, it would need to continue to balance that breadth with heightened 
focus on specific risk and performance topics. It viewed its increased 
use of member visits and briefings as important tool towards achieving 
that heightened focus. Overall the committee considered that its current 
membership provided a well-balanced and experienced resource, and also 
noted the valuable contribution made by Mr Wilson in his capacity as the 
independent expert.

Gulf of Mexico committee
Chairman’s introduction
The Gulf of Mexico committee was very active in 2011, meeting 16 times 
over the course of the year. In addition to overseeing efforts to mitigate the 
effects of the spill, the company’s strategy for resolving claims, and actions 
to restore the group’s reputation, the committee focused a considerable 
portion of its attention on legal matters. Some of these legal matters 
included settlements reached with BP’s partners in the Macondo well and 
various contractors, preparations for the upcoming trial in the Multi-District 
Litigation and ongoing governmental investigations.

We have been joined in meetings by the leadership, management 

and counsel of the Gulf Coast Restoration Organization (GCRO), which was 
formed in mid-2010 to manage the company’s long-term response to the 
tragic Deepwater Horizon oil spill. The committee members’ understanding 
of the important issues and numerous interdependencies has been 
facilitated by the frequency of meetings and the breadth of topics covered.
I believe the committee has maintained a rigorous approach to its 

work, providing effective oversight on behalf of the board, to which reports 
are provided following committee meetings. The report below summarizes 
the activities of the committee in 2011. I anticipate 2012 will be an equally 
demanding year but the committee is well prepared to conduct its tasks.

In 2011 the membership of the Gulf of Mexico committee remained the 
same as in 2010, including two US-based non-executive directors and the 
previous and present chairmen of the SEEAC. There is cross-membership 
with the audit committee, helping to inform discussions at the latter 
regarding financial controls and incident-related costs. Frank Bowman 
joined the committee in February 2012.

Each meeting of the committee is attended by Lamar McKay, 

President and CEO of the GCRO, and by Jack Lynch, chief counsel to the 
GCRO. The chairman, group chief executive and group general counsel join 
the meeting whenever possible. Meetings also include private sessions 
attended by non-executive members only.

Committee role and structure
The purpose of the committee is to provide non-executive oversight of the 
GCRO and to support efforts to rebuild trust in BP and BP’s reputation with 
a particular focus on the US.

The work of the committee is fully integrated with the work of the 
board on reputation, safety, strategy and financial planning, and the board 
retains ultimate accountability for oversight of the group’s response to the 
incident.

Directors are invited to attend and observe committee meetings. 

Committee meeting minutes are circulated to the board, and the 
committee chairman provides verbal reports on the committee’s activities 
at board meetings.

The committee met 16 times in 2011.
During the course of 2011, the committee has undertaken the 

following tasks:
•	 Oversee and receive regular reports on work undertaken to mitigate the 

effects of the oil spill in the Gulf of Mexico area.

•	 Oversee GCRO’s co-ordinated response programme for affected 

communities and states, along with its strategies for managing external 
relationships on issues relating to the incident.

•	 Oversee the legal strategy for litigation and investigations involving the 

group arising from the incident or its aftermath.

•	 Oversee GCRO’s strategy for resolving claims, recognizing the 

independent role of the Gulf Coast Claims Facility.

reputation in the US.

Committee processes
Information and advice
The committee receives its information from the leadership of the GCRO 
and external advisers. Privileged legal briefings are regularly provided by 
the group general counsel and chief counsel for the GCRO, who are joined 
on occasion in committee meetings by other internal and external legal 
counsel.

BP’s internal audit function has conducted reviews of various 
GCRO activities and processes, and these have been summarized for 
the committee’s review. Primary monitoring of financial risk associated 
with GCRO’s activities is undertaken by the audit committee. Safety risks 
related to GCRO’s activities are monitored by the SEEAC.

Training and visits
The high frequency of meetings in 2011 has facilitated the committee’s 
understanding of the important issues and numerous interdependencies. 
Three of these meetings were held in the US and were of extended 
duration, providing the opportunity for the committee to interact with 
members of the GCRO leadership team.

Committee activities
The committee’s activities have included the following:
•	 Legal: legal updates from the chief counsel to the GCRO have formed 
a significant part of the committee’s agenda, given the breadth and 
pace of activities. The committee has overseen the GCRO’s integrated 
legal approach, which incorporates all government, civil and criminal 
investigations, the Multi-District Litigation, the Natural Resource Damage 
Assessment process, and legal aspects of the claims processes. The 
committee has overseen the company’s preparation for trial, as well as 
the settlements entered into with the other working interest owners 
in the Macondo well and with some sub-contractors working on the 
development. The committee has continued to monitor engagement 
with other responsible parties and contractors.

•	 Claims: the committee has monitored the status of claims from 

individuals and businesses administered by the independent Gulf Coast 
Claims Facility; and the status of claims from government entities, which 
continue to be administered by BP. Assessments of potential future 
claims for provisioning purposes are reviewed by the audit committee.

•	 Remediation: the committee has received regular updates on the 

progress of clean-up and remediation activities. The committee also 
monitored discussions with Natural Resource Trustees, with whom 
agreement was reached on early restoration projects.

•	 GCRO controls: the committee oversaw the continued development 
of financial controls underpinning the breadth of the GCRO’s complex 
tasks. The audit committee remains the primary forum for the oversight 
of these controls and associated audits.

Chairman’s introduction
I chair both the nomination and the chairman’s committees. Set out 
below are reports on their activities during the year. As in previous years 
there is often an overlap between the work of the committees as the 
nomination committee may wish to sound out the view of the other 
non-executive directors in the chairman’s committee on a particular issue, 
such as executive succession or the skills and experience needed for non-
executive directors.

The committee met five times during 2011.

Committee’s role
The committee identifies, evaluates and recommends candidates for the 
appointment or re-appointment as directors and for the appointment of the 
company secretary.

The committee keeps the mix of knowledge, skills and experience 

of the board under regular review (in consultation with the chairman’s 
committee) to ensure an orderly succession of directors. The outside 
directorships and broader commitments of the non-executive directors are 
also monitored by the nomination committee.

Committee activities
The committee reviewed the independence and roles of each of the 
directors prior to recommending them for re-election at the 2011 AGM. It 
also discussed the composition of the board and its committees in terms 
of service, skills and diversity.

Since the start of 2011, there were changes to the composition of 
the board, with Phuthuma Nhleko, Andrew Shilston and Professor Dame 
Ann Dowling joining on 1 February 2011, 1 January 2012 and 3 February 
2012 respectively. The committee retained the services of external 
advisers Egon Zehnder and Odgers to assist with the identification of 
potential candidates over the period.

In undertaking its search for potential candidates for board 
membership, the committee carried out a review of skills and experience 
of existing board members and considered this against the board 
succession plan based on tenure and other factors, including diversity. 
This process enabled the committee to develop a list of selection criteria 
for future appointments, which it then used with its external advisers to 
develop a shortlist. Based on this, the committee determined an initial 
focus on candidates in the fields of science and technology.

The committee also considered the succession of our chief financial 
officer and the skillset and experience needed in light of the role and 
the company’s strategy. There was an extensive process in which Egon 
Zehnder advised the committee on both internal and external candidates. 
The committee made its recommendation to the chairman’s committee, 
and CFO succession was then discussed by all the non-executive directors. 
It was agreed that Brian Gilvary, previously deputy chief financial officer, 
was the preferred candidate and he became CFO on 1 January 2012.

During the year the committee considered the recommendations 

of Lord Davies’ report on gender diversity. In line with the report, the 
committee agreed to a set of aspirational targets to work towards by 2015 
and recommended changes to BP’s board governance principles to include 
a policy on board diversity, which emphasizes considerations of diversity, 
inclusiveness and meritocracy when considering board composition. The 
committee has determined to develop during 2012 a set of measurable 
objectives for implementing its board diversity policy on which it will report 
back to shareholders.

At the end of the year, the committee undertook its annual 

examination of its effectiveness and performance, using an internally 
administered questionnaire. As part of its evaluation, the committee 
considered its role and its task for the year. The evaluation concluded that 
the committee had worked well and had improved its focus on diversity. 
Going forward the committee wishes to focus on agenda setting and 
papers with a view to improving time management and workload.

Corporate governanceCommittee’s role
The committee is comprised of the chairman and all the non-executive 
directors.

The main tasks of the committee are:

•	 Evaluating the performance and effectiveness of the group chief 

executive.

•	 Reviewing the structure and effectiveness of the business organization 

of BP.

•	 Reviewing the systems for senior executive development and 

determining the succession plan for the group chief executive, executive 
directors and other senior members of executive management.

•	 Determining any other matter which is appropriate to be considered by 

all of the non-executive directors.

•	 Opining on any matter referred to it by the chairman of any committee 

comprised solely of non-executive directors.

Committee activities
The committee held private discussions between the non-executive 
directors during the year on key issues for the group, including its strategic 
direction, activities in Russia and risk management.

The chairman’s committee worked closely with the nomination 
committee in matters around executive and non-executive succession, 
in particular the succession of the chief financial officer (CFO) and in 
redefining the roles of the CFO and executive director for corporate 
business activities. It was agreed that outgoing CFO Byron Grote would 
stay on the board as an executive director with responsibility for BP’s 
corporate business activities, including its integrated supply and trading 
operations, Alternative Energy, shipping, technology and remediation 
activities.

The committee evaluated the performance of the group chief 
executive at the half year and the full year. It reviewed succession planning 
within the group and discussed the structure of the senior executive team.
The outcomes of the main board evaluation were discussed within 
the chairman’s committee. The committee also reviewed the skills of the 
board and discussed what would be needed to meet the challenges of the 
company’s strategy. Issues of governance around committees and their 
composition were examined. Led by the senior independent director, the 
committee evaluated the performance of the chairman as part of BP’s 
annual evaluation programme for the board and its directors.

Facilitated by the senior independent director, the committee met 

to discuss an approach to the chairman by the Volvo Group to become 
their part-time, non-executive chairman. The discussion was held without 
the presence of the chairman and considered the time commitment of this 
additional role, given that Carl-Henric Svanberg would be stepping down 
from his existing non-executive directorship at Ericsson before taking on 
the potential position at Volvo. The committee concluded it was supportive 
of the chairman taking on this additional role.

Risk management and internal 
control review

In discharging its responsibility for the company’s risk management and 
internal control systems under the UK Corporate Governance Code, the 
board, through its governance principles, requires the group chief executive 
to operate with a comprehensive system of controls and internal audit 
to identify and manage the risks that are material to BP. The governance 
principles are reviewed periodically by the board and are consistent with 
the requirements of the UK Corporate Governance Code including principle 
C.2 (risk management and internal control).

The board has an established process by which the effectiveness 

of the system of internal control (which includes the risk management 
system) is reviewed as required by provision C.2.1 of the UK Corporate 
Governance Code. This process enables the board and its committees 
to consider the system of internal control being operated for managing 
significant risks, including strategic, safety and operational and compliance 
and control risks, throughout the year. Material joint ventures and 
associates have not been dealt with as part of the group in this process.
As part of this process, the board and the audit, Gulf of Mexico 
and safety, ethics and environment assurance committees requested, 
received and reviewed reports from executive management, including 
management of the business segments, divisions and functions, at their 
regular meetings.

In considering the systems, the board noted that such systems are 

designed to manage, rather than eliminate, the risk of failure to achieve 
business objectives and can only provide reasonable, and not absolute, 
assurance against material misstatement or loss.

During the year, the board, through its committees, regularly 
reviewed with executive management processes whereby risks are 
identified, evaluated and managed. These processes were in place for the 
year under review, remain current at the date of this report and accord 
with the guidance on the UK Corporate Governance Code provided by the 
Financial Reporting Council. In December 2011, the board considered the 
group’s significant risks within the context of the annual plan presented by 
the group chief executive.

A joint meeting of the audit and safety, ethics and environment 

assurance committees in February 2012 reviewed a report from 
the general auditor as part of the board’s annual review of the risk 
management and internal control systems. The report described the annual 
summary of internal audit’s consideration of elements of BP’s system of 
internal control over significant risks arising in the categories of strategic, 
safety and operational and compliance and control and considered the 
control environment for the group. The report also highlighted the results 
of audit work conducted during the year and the remedial actions taken by 
management in response to significant failings and weaknesses identified.

During the year, these committees engaged with management, the 
general auditor and other monitoring and assurance providers (such as the 
group ethics and compliance officer, head of safety and operational risk and 
the external auditor) on a regular basis to monitor the management of risks. 
Significant incidents that occurred and management’s response to them 
were considered by the appropriate committee and reported to the board.

Subject to determining any additional appropriate actions arising 
from items still in process, the board is satisfied that, where significant 
failings or weaknesses in internal controls were identified during the year, 
appropriate remedial actions were taken or are being taken.

In the board’s view, the information it received was sufficient to 

enable it to review the effectiveness of the company’s system of internal 
control in accordance with the Internal Control Revised Guidance for 
Directors (Turnbull).

BP Annual Report and Form 20-F 2011    133

Corporate governanceCorporate governanceCorporate governance practices

Code of ethics

The company has adopted a code of ethics for its group chief executive, 
chief financial officer, group controller, general auditor and chief accounting 
officer as required by the provisions of Section 406 of the Sarbanes-Oxley 
Act of 2002 and the rules issued by the SEC. There have been no waivers 
from the code of ethics relating to any officers.

BP also has a code of conduct, which is applicable to all employees. 

This was updated (and published) on 1 January 2012.

In the US, BP ADSs are listed on the New York Stock Exchange (NYSE). 
The significant differences between BP’s corporate governance practices 
as a UK company and those required by NYSE listing standards for US 
companies are listed as follows:

Independence
BP has adopted a robust set of board governance principles, which 
reflect the UK Corporate Governance Code and its principles-based 
approach to corporate governance. As such, the way in which BP makes 
determinations of directors’ independence differs from the NYSE rules.

BP’s board governance principles require that all non-executive directors 
be determined by the board to be ‘independent in character and judgement and 
free from any business or other relationship which could materially interfere 
with the exercise of their judgement’. The BP board has determined that, in 
its judgement, all of the non-executive directors are independent. In doing so, 
however, the board did not explicitly take into consideration the independence 
requirements outlined in the NYSE’s listing standards.

Committees
BP has a number of board committees that are broadly comparable in 
purpose and composition to those required by NYSE rules for domestic 
US companies. For instance, BP has a chairman’s (rather than executive) 
committee, nomination (rather than nominating/corporate governance) 
committee and remuneration (rather than compensation) committee. 
BP also has an audit committee, which NYSE rules require for both US 
companies and foreign private issuers. These committees are composed 
solely of non-executive directors whom the board has determined to be 
independent, in the manner described above.

The BP board governance principles prescribe the composition, 
main tasks and requirements of each of the committees (see the board 
committee reports). BP has not, therefore, adopted separate charters for 
each committee.

Under US securities law and the listing standards of the NYSE, 

BP is required to have an audit committee that satisfies the requirements 
of Rule 10A-3 under the Exchange Act and Section 303A.06 of the NYSE 
Listed Company Manual. BP’s audit committee complies with these 
requirements. The BP audit committee does not have direct responsibility 
for the appointment, re-appointment or removal of the independent 
auditors – instead, it follows the UK Companies Act 2006 by making 
recommendations to the board on these matters for it to put forward for 
shareholder approval at the AGM.

One of the NYSE’s additional requirements for the audit 
committee states that at least one member of the audit committee is to 
have ‘accounting or related financial management expertise’. The board 
determined that Brendan Nelson possessed such expertise and also 
possesses the financial and audit committee experiences set forth in both 
the UK Corporate Governance Code and SEC rules (see audit committee 
report). Mr Nelson is the audit committee financial expert as defined in 
Item 16A of Form 20-F.

Shareholder approval of equity compensation plans
The NYSE rules for US companies require that shareholders must be given 
the opportunity to vote on all equity-compensation plans and material 
revisions to those plans. BP complies with UK requirements that are 
similar to the NYSE rules. The board, however, does not explicitly take 
into consideration the NYSE’s detailed definition of what are considered 
‘material revisions’.

Code of ethics
The NYSE rules require that US companies adopt and disclose a code of 
business conduct and ethics for directors, officers and employees. BP has 
adopted a code of conduct, which applies to all employees, and has board 
governance principles that address the conduct of directors. In addition 
BP has adopted a code of ethics for senior financial officers as required by 
the SEC. BP considers that these codes and policies address the matters 
specified in the NYSE rules for US companies.

134    BP Annual Report and Form 20-F 2011

Corporate governanceThe company’s internal control over financial reporting includes policies and 
procedures that pertain to the maintenance of records that, in reasonable 
detail, accurately and fairly reflect transactions and dispositions of assets; 
provide reasonable assurances that transactions are recorded as necessary 
to permit preparation of financial statements in accordance with IFRS 
and that receipts and expenditures are being made only in accordance 
with authorizations of management and the directors of BP; and provide 
reasonable assurance regarding prevention or timely detection of 
unauthorized acquisition, use or disposition of BP’s assets that could have 
a material effect on our financial statements. BP’s internal control over 
financial reporting as of 31 December 2011 has been audited by  
Ernst & Young LLP, an independent registered public accounting firm, 
as stated in their report appearing on page 177 of this Annual Report and 
Form 20-F 2011.

Changes in internal control over financial reporting
There were no changes in the group’s internal controls over financial 
reporting that occurred during the period covered by the Form 20-F that 
have materially affected or are reasonably likely to materially affect our 
internal controls over financial reporting.

Controls and procedures

Evaluation of disclosure controls and procedures
The company maintains ‘disclosure controls and procedures’, as such term 
is defined in Exchange Act Rule 13a-15(e), that are designed to ensure 
that information required to be disclosed in reports the company files or 
submits under the Exchange Act is recorded, processed, summarized and 
reported within the time periods specified in the Securities and Exchange 
Commission rules and forms, and that such information is accumulated 
and communicated to management, including the company’s group 
chief executive and chief financial officer, as appropriate, to allow timely 
decisions regarding required disclosure.

In designing and evaluating our disclosure controls and procedures, 

our management, including the group chief executive and chief financial 
officer, recognize that any controls and procedures, no matter how 
well designed and operated, can provide only reasonable, not absolute, 
assurance that the objectives of the disclosure controls and procedures 
are met. Because of the inherent limitations in all control systems, no 
evaluation of controls can provide absolute assurance that all control 
issues and instances of fraud, if any, within the company have been 
detected. Further, in the design and evaluation of our disclosure controls 
and procedures our management necessarily was required to apply its 
judgement in evaluating the cost-benefit relationship of possible controls 
and procedures. Also, we have investments in certain unconsolidated 
entities. As we do not control these entities, our disclosure controls and 
procedures with respect to such entities are necessarily substantially 
more limited than those we maintain with respect to our consolidated 
subsidiaries. Because of the inherent limitations in a cost-effective control 
system, misstatements due to error or fraud may occur and not be 
detected. The company’s disclosure controls and procedures have been 
designed to meet, and management believes that they meet, reasonable 
assurance standards.

The company’s management, with the participation of the 
company’s group chief executive and chief financial officer, has evaluated 
the effectiveness of the company’s disclosure controls and procedures 
pursuant to Exchange Act Rule 13a-15(b) as of the end of the period 
covered by this annual report. Based on that evaluation, the group chief 
executive and chief financial officer have concluded that the company’s 
disclosure controls and procedures were effective at a reasonable 
assurance level.

Management’s report on internal control over financial reporting
Management of BP is responsible for establishing and maintaining adequate 
internal control over financial reporting. BP’s internal control over financial 
reporting is a process designed under the supervision of the principal 
executive and financial officers to provide reasonable assurance regarding 
the reliability of financial reporting and the preparation of BP’s financial 
statements for external reporting purposes in accordance with IFRS.

As of the end of the 2011 fiscal year, management conducted an 

assessment of the effectiveness of internal control over financial reporting 
in accordance with the Internal Control Revised Guidance for Directors on 
the Combined Code (Turnbull). Based on this assessment, management 
has determined that BP’s internal control over financial reporting as of 
31 December 2011 was effective.

and services

Memorandum and Articles  
of Association

The audit committee has established policies and procedures for the 
engagement of the independent registered public accounting firm, Ernst 
& Young LLP, to render audit and certain assurance and tax services. The 
policies provide for pre-approval by the audit committee of specifically 
defined audit, audit-related, tax and other services that are not prohibited 
by regulatory or other professional requirements. Ernst & Young are 
engaged for these services when its expertise and experience of BP are 
important. Most of this work is of an audit nature. Tax services were 
awarded either through a full competitive tender process or following an 
assessment of the expertise of Ernst & Young relative to that of other 
potential service providers. These services are for a fixed term.

Under the policy, pre-approval is given for specific services within 

the following categories: advice on accounting, auditing and financial 
reporting matters; internal accounting and risk management control 
reviews (excluding any services relating to information systems design 
and implementation); non-statutory audit; project assurance and advice on 
business and accounting process improvement (excluding any services 
relating to information systems design and implementation relating to BP’s 
financial statements or accounting records); due diligence in connection 
with acquisitions, disposals and joint ventures (excluding valuation or 
involvement in prospective financial information); income tax and indirect 
tax compliance and advisory services; employee tax services (excluding 
tax services that could impair independence); provision of, or access 
to, Ernst & Young publications, workshops, seminars and other training 
materials; provision of reports from data gathered on non-financial policies 
and information; and assistance with understanding non-financial regulatory 
requirements. BP operates a two-tier system for audit and non-audit 
services. For audit related services, the audit committee has a pre-
approved aggregate level, within which specific work may be approved by 
management. Non-audit services, including tax services, are pre-approved 
for management to authorize per individual engagement, but above a 
defined level must be approved by the chairman of the audit committee 
or the full committee. The audit committee has delegated to the chairman 
of the audit committee authority to approve permitted services provided 
that the chairman reports any decisions to the committee at its next 
scheduled meeting. Any proposed service not included in the approved 
service list must be approved in advance by the audit committee chairman 
and reported to the committee, or approved by the full audit committee in 
advance of commencement of the engagement.

The audit committee evaluates the performance of the auditors 
each year. The audit fees payable to Ernst & Young are reviewed by the 
committee in the context of other global companies for cost effectiveness. 
The committee keeps under review the scope and results of audit work 
and the independence and objectivity of the auditors. External regulation 
and BP policy requires the auditors to rotate their lead audit partner every 
five years. (See Financial statements – Note 16 on page 209 and Audit 
committee report on page 127 for details of audit fees.)

The following summarizes certain provisions of the company’s 
Memorandum and Articles of Association and applicable English law. This 
summary is qualified in its entirety by reference to the UK Companies Act 
2006 (Act) and the company’s Memorandum and Articles of Association. 
For information on where investors can obtain copies of the Memorandum 
and Articles of Association see Documents on display on page 170.

At the AGM held on 17 April 2008 shareholders voted to adopt new 

Articles of Association, largely to take account of changes in UK company 
law brought about by the Act. Further amendments to the Articles of 
Association were approved by shareholders at the AGM held on 15 April 
2010. These amendments reflect the full implementation of the Act, 
among other matters.

Objects and purposes
BP is incorporated under the name BP p.l.c. and is registered in England 
and Wales with the registered number 102498. The provisions regulating 
the operations of the company, known as its ‘objects’, were historically 
stated in a company’s memorandum. The Act abolished the need to have 
object provisions and so at the AGM held on 15 April 2010 shareholders 
approved the removal of its objects clause together with all other 
provisions of its Memorandum that, by virtue of the Act, are treated as 
forming part of the company’s Articles of Association.

Directors
The business and affairs of BP shall be managed by the directors. The 
company’s Articles of Association provide that directors may be appointed 
by the existing directors or by the shareholders in a general meeting. Any 
person appointed by the directors will hold office only until the next general 
meeting and will then be eligible for re-election by the shareholders. There 
is no requirement for a director to retire on reaching any age.

The Articles of Association place a general prohibition on a director 
voting in respect of any contract or arrangement in which the director has 
a material interest other than by virtue of such director’s interest in shares 
in the company. However, in the absence of some other material interest 
not indicated below, a director is entitled to vote and to be counted in a 
quorum for the purpose of any vote relating to a resolution concerning the 
following matters:
•	 The giving of security or indemnity with respect to any money lent or 

obligation taken by the director at the request or benefit of the company 
or any of its subsidiaries.

•	 Any proposal in which the director is interested, concerning the 

underwriting of company securities or debentures or the giving of any 
security to a third party for a debt or obligation of the company or any of 
its subsidiaries.

•	 Any proposal concerning any other company in which the director is 
interested, directly or indirectly (whether as an officer or shareholder 
or otherwise) provided that the director and persons connected with 
such director are not the holder or holders of 1% or more of the voting 
interest in the shares of such company.

•	 Any proposal concerning the purchase or maintenance of any insurance 

policy under which the director may benefit.

136    BP Annual Report and Form 20-F 2011

Corporate governanceThe Act requires a director of a company who is in any way interested in 
a contract or proposed contract with the company to declare the nature 
of the director’s interest at a meeting of the directors of the company. 
The definition of ‘interest’ includes the interests of spouses, children, 
companies and trusts. The Act also requires that a director must avoid a 
situation where a director has, or could have, a direct or indirect interest 
that conflicts, or possibly may conflict, with the company’s interests. The 
Act allows directors of public companies to authorize such conflicts where 
appropriate, if a company’s Articles of Association so permit. BP’s Articles 
of Association permit the authorization of such conflicts. The directors may 
exercise all the powers of the company to borrow money, except that the 
amount remaining undischarged of all moneys borrowed by the company 
shall not, without approval of the shareholders, exceed the amount paid 
up on the share capital plus the aggregate of the amount of the capital and 
revenue reserves of the company. Variation of the borrowing power of the 
board may only be affected by amending the Articles of Association.

Remuneration of non-executive directors shall be determined in the 

aggregate by resolution of the shareholders. Remuneration of executive 
directors is determined by the remuneration committee. This committee is 
made up of non-executive directors only. There is no requirement of share 
ownership for a director’s qualification.

Dividend rights; other rights to share in company profits; capital calls
If recommended by the directors of BP, BP shareholders may, by 
resolution, declare dividends but no such dividend may be declared in 
excess of the amount recommended by the directors. The directors may 
also pay interim dividends without obtaining shareholder approval. No 
dividend may be paid other than out of profits available for distribution, 
as determined under IFRS and the Act. Dividends on ordinary shares are 
payable only after payment of dividends on BP preference shares. Any 
dividend unclaimed after a period of 12 years from the date of declaration 
of such dividend shall be forfeited and reverts to BP.

The directors have the power to declare and pay dividends in any 

currency provided that a sterling equivalent is announced. It is not the 
company’s intention to change its current policy of paying dividends in US 
dollars.

At the company’s AGM held on 15 April 2010, shareholders 
approved the introduction of a Scrip Dividend Programme (Programme) and 
to include provisions in the Articles of Association to enable the company 
to operate the Programme. The Programme enables ordinary shareholders 
and BP ADS holders to elect to receive new fully paid ordinary shares (or 
BP ADSs in the case of BP ADS holders) instead of cash. The operation 
of the Programme is always subject to the directors’ decision to make 
the scrip offer available in respect of any particular dividend. Should the 
directors decide not to offer the scrip in respect of any particular dividend, 
cash will automatically be paid instead.

Apart from shareholders’ rights to share in BP’s profits by dividend 

(if any is declared or announced), the Articles of Association provide that 
the directors may set aside:
•	 A special reserve fund out of the balance of profits each year to make up 

any deficit of cumulative dividend on the BP preference shares.

•	 A general reserve out of the balance of profits each year, which shall 
be applicable for any purpose to which the profits of the company 
may properly be applied. This may include capitalization of such sum, 
pursuant to an ordinary shareholders’ resolution, and distribution to 
shareholders as if it were distributed by way of a dividend on the 
ordinary shares or in paying up in full unissued ordinary shares for 
allotment and distribution as bonus shares.

Any such sums so deposited may be distributed in accordance with the 
manner of distribution of dividends as described above.

Holders of shares are not subject to calls on capital by the 
company, provided that the amounts required to be paid on issue have 
been paid off. All shares are fully paid.

Voting rights
The Articles of Association of the company provide that voting on 
resolutions at a shareholders’ meeting will be decided on a poll other than 
resolutions of a procedural nature, which may be decided on a show of 
hands. If voting is on a poll, every shareholder who is present in person 
or by proxy has one vote for every ordinary share held and two votes for 
every £5 in nominal amount of BP preference shares held. If voting is 
on a show of hands, each shareholder who is present at the meeting in 
person or whose duly appointed proxy is present in person will have one 
vote, regardless of the number of shares held, unless a poll is requested. 
Shareholders do not have cumulative voting rights.

Holders of record of ordinary shares may appoint a proxy, including 

a beneficial owner of those shares, to attend, speak and vote on their 
behalf at any shareholders’ meeting.

Record holders of BP ADSs are also entitled to attend, speak 

and vote at any shareholders’ meeting of BP by the appointment by the 
approved depositary, JPMorgan Chase Bank N.A., of them as proxies in 
respect of the ordinary shares represented by their ADSs. Each such proxy 
may also appoint a proxy. Alternatively, holders of BP ADSs are entitled to 
vote by supplying their voting instructions to the depositary, who will vote 
the ordinary shares represented by their ADSs in accordance with their 
instructions.

Proxies may be delivered electronically.
Matters are transacted at shareholders’ meetings by the proposing 

and passing of resolutions, of which there are two types: ordinary or 
special. An annual general meeting must be held once in every year.

An ordinary resolution requires the affirmative vote of a majority of 
the votes of those persons voting at a meeting at which there is a quorum. 
A special resolution requires the affirmative vote of not less than three-
fourths of the persons voting at a meeting at which there is a quorum. Any 
AGM requires 21 days’ notice. The notice period for a general meeting is 
14 days subject to the company obtaining annual shareholder approval, 
failing which, a 21-day notice period will apply.

Liquidation rights; redemption provisions
In the event of a liquidation of BP, after payment of all liabilities and 
applicable deductions under UK laws and subject to the payment of 
secured creditors, the holders of BP preference shares would be entitled 
to the sum of (i) the capital paid up on such shares plus, (ii) accrued and 
unpaid dividends and (iii) a premium equal to the higher of (a) 10% of the 
capital paid up on the BP preference shares and (b) the excess of the 
average market price over par value of such shares on the LSE during the 
previous six months. The remaining assets (if any) would be divided pro 
rata among the holders of ordinary shares.

Without prejudice to any special rights previously conferred on 
the holders of any class of shares, BP may issue any share with such 
preferred, deferred or other special rights, or subject to such restrictions as 
the shareholders by resolution determine (or, in the absence of any such 
resolutions, by determination of the directors), and may issue shares that 
are to be or may be redeemed.

Variation of rights
The rights attached to any class of shares may be varied with the consent 
in writing of holders of 75% of the shares of that class or on the adoption 
of a special resolution passed at a separate meeting of the holders of the 
shares of that class. At every such separate meeting, all of the provisions 
of the Articles of Association relating to proceedings at a general meeting 
apply, except that the quorum with respect to a meeting to change the 
rights attached to the preference shares is 10% or more of the shares of 
that class, and the quorum to change the rights attached to the ordinary 
shares is one-third or more of the shares of that class.

Corporate governanceCorporate governanceShareholders’ meetings and notices
Shareholders must provide BP with a postal or electronic address in the 
UK to be entitled to receive notice of shareholders’ meetings. Holders of 
BP ADSs are entitled to receive notices under the terms of the deposit 
agreement relating to BP ADSs. The substance and timing of notices is 
described on page 137 under the heading Voting rights.

Under the Act, the AGM of shareholders must be held within 

the six-month period once every year. All general meetings shall be held 
at a time and place determined by the directors within the UK. If any 
shareholders’ meeting is adjourned for lack of quorum, notice of the time 
and place of the meeting may be given in any lawful manner, including 
electronically. Powers exist for action to be taken either before or at the 
meeting by authorized officers to ensure its orderly conduct and safety of 
those attending.

Limitations on voting and shareholding
There are no limitations imposed by English law or the company’s 
Memorandum or Articles of Association on the right of non-residents or 
foreign persons to hold or vote the company’s ordinary shares or BP ADSs, 
other than limitations that would generally apply to all of the shareholders.

Disclosure of interests in shares
The Act permits a public company to give notice to any person whom the 
company believes to be or, at any time during the three years prior to the 
issue of the notice, to have been interested in its voting shares requiring 
them to disclose certain information with respect to those interests. Failure 
to supply the information required may lead to disenfranchisement of the 
relevant shares and a prohibition on their transfer and receipt of dividends 
and other payments in respect of those shares. In this context the term 
‘interest’ is widely defined and will generally include an interest of any kind 
whatsoever in voting shares, including any interest of a holder of BP ADSs.

BP Annual Report and Form 20-F 2011    00 Directors’ remuneration reportRemuneration overview

Dear shareholder,

For the senior executives of BP, remuneration is directly linked to strategy, 
strongly performance related and heavily weighted towards the long term. 
In a year of consolidation following the events of 2010, the company 
achieved a creditable performance overall in 2011. The outcome of the 
various plans that make up 2011 total remuneration for executive directors 
is set out in the table opposite.

The remuneration committee is keenly aware of its responsibility to 

balance sometimes conflicting perspectives in making judgements on 
senior executive pay. We recognize a concern by government, and society 
at large, of excess in this area, but cannot ignore the reality of a global 
competitive market for top executive talent. We respect investors’ 
expectation for pay to be strongly tied to performance while also wanting 
to ensure that executives receive fair reward for their achievements.
The committee’s commitment to exercising judgement in a 

balanced way and being transparent in communicating its conclusions 
continues. In years where performance has been strong, bonuses have 
reflected that and when performance has been poor, bonuses have 
appropriately been reduced and even in some cases, as in 2010, 
eliminated. The long-term plan has, over the last five years, vested less 
than 10% of the possible shares, reflecting the impact of major incidents.
In this context, the committee carefully considered 2011 
performance against targets set at the start of the year. Safety and risk 
management metrics were all met or exceeded including recordable injury 
frequency, loss of primary containment, implementation of change 
programmes and capability building. Group results were at or near target 
for financial metrics, including replacement cost profit, cash costs, 
upstream operating cash and downstream profitability. External survey 
results show some modest recovery in the company’s external reputation, 
as well as good results on internal employee morale. The overall 
assessment of group results based on the above was judged to be 
‘on-target’ for the group as a whole.

Bob Dudley’s bonus was based entirely on group results, resulting in an 
amount, including the deferred element, at ‘on-target’ level. Iain Conn’s and 
Byron Grote’s bonuses were based 70% on group results and 30% on 
their respective business or functional units. Mr Conn’s results met or 
exceeded targets resulting in a bonus just above ‘on-target’, and Dr Grote’s 
largely met resulting in an ‘on-target’ bonus. In all cases one-third of their 
bonus is deferred into shares on a mandatory basis, matched, and will vest 
in three years subject to a review of safety and environmental sustainability 
during the period. They may elect to defer an additional one-third into shares 
on the same basis as the mandatory deferral, which they all chose to do for 
this year’s bonus. All of the above is reflected in the table opposite.

The 2009-2011 share element included performance conditions 

relating to total shareholder return, production growth, group net income, 
and Refining and Marketing profitability – all relative to the other oil majors. 
Of these all but Refining and Marketing profitability missed the level 
required to vest. Refining and Marketing profitability compared to the other 
oil majors was strong, and based on this, the overall vesting was 16.67% 
of the shares – again reflected in the table opposite. The committee 
concluded that the result from a straight numerical assessment relative to 
agreed metrics provided an appropriate vesting level in light of overall 
company performance during the period.

For 2012 the overall policy for executive directors will remain largely 
unchanged, as summarized below. The committee will continue to monitor 
trends and external perspectives in reviewing the quantum and structure of 
total remuneration. It will also continue to operate with independence and 
rigour in making its judgements. Ultimately decisions will be guided by our 
commitment to both shareholder interests and executive engagement.

Amounts shown are in the currency received by executive directors. Annual bonuses are shown in the year they were earned.

 a  Increase in salary for Mr Dudley relates to his appointment to group chief executive in October 2010.
 b  This reflects the amount of total bonus paid in cash with the deferred bonus as set out in the conditional equity section.
 c  This amount includes costs of London accommodation and any tax liability thereon that ceased at the end of 2010 following Mr Dudley’s appointment as group chief executive.
 d  As for all employees affected by the new UK pension tax limits and who wished to remain within these limits, with effect from April 2011, Mr Conn received a cash supplement of 35% of basic salary in 
lieu of future service pension accrual amounting to £191,625.
 e  Mr Dudley and Dr Grote hold shares in the form of ADSs. The above numbers reflect calculated equivalent in ordinary shares.
 f  Represents vesting of shares made at the end of the relevant performance period based on performance achieved under rules of the plan and includes re-invested dividends on the shares vested. The 
market price of ordinary shares on 14 February 2012 was £4.98 and for ADSs was $46.49.
 g  There was no vesting under the performance share element. The shares that vested in February 2011 for Mr Conn pertained to a separate restricted award made in 2008.
 h  It is anticipated that the 2011 deferred bonus award will be made in early March 2012. The number of deferred shares is calculated using the three-day average share price following the full-year result 
announcement which was £4.84/share and $46.68/ADS in February 2011 and £4.91/share and $46.70/ADS in February 2012. Both deferred and matched shares are subject to a safety and environmental 
hurdle over the three-year deferral period.

Executive directors’ remuneration
Remuneration committee

During the year the committee met seven times, and was made up of the 
following independent non-executive directors:
Mr Antony Burgmans (chairman from 2011 Annual General Meeting (AGM))
Mr George David
Mr Ian Davis

Dr DeAnne Julius was chairman of the committee until her retirement at 
the 2011 AGM. Mr Svanberg has attended all meetings. 

The group chief executive is consulted on matters relating to the other 
executive directors and senior executives who report to him and on 
matters relating to the performance of the company; neither he nor the 
chairman of the board participate in decisions on their own remuneration.

The committee’s tasks are set out in the board governance principles:
•	 To determine, on behalf of the board, the terms of engagement and 

remuneration of the group chief executive and the executive directors 
and to report on these to the shareholders.

•	 To determine, on behalf of the board, matters of policy over which the 
company has authority regarding the establishment or operation of 
the company’s pension schemes of which the executive directors are 
members.

•	 To nominate, on behalf of the board, any trustees (or directors of 

corporate trustees) of such schemes.

•	 To review and approve the policies and actions being applied by the 
group chief executive in remunerating senior executives other than 
executive directors to ensure alignment and proportionality.

Executive directors’ remuneration 2011

This section contains detail on executive directors’ remuneration including 
salary, annual bonus and deferred bonus relating to 2011 and the share 
element for the performance period 2009-2011.

Salary
Mr Dudley’s current salary of $1,700,000 was unchanged during 2011. 
As reported in last year’s remuneration report, Mr Conn’s and Dr Grote’s 
salaries were increased in April 2011 to £730,000 and $1,442,000 
respectively, their first increase since 2008.

Annual bonus
Framework
All executive directors were eligible for an overall annual bonus, including 
deferral, of 150% of salary at target and a maximum of 225% of salary. 
Mr Dudley’s annual bonus was based entirely on group results and 
Mr Conn’s and Dr Grote’s based 70% on group results and 30% on their 
respective segment and function.

Measures and targets for the annual bonus were set at the start of 
the year and were derived from the company’s annual plan which, in turn, 
reflected its strategic priorities of reinforcing safety and risk management, 
rebuilding trust and reinforcing value creation. Targets are set so that 
meeting plan equates to on-target bonus.

At group level, the safety and risk management component 

included targets for recordable injury frequency, loss of primary 
containment and implementation of change programmes. Rebuilding trust 
was focused on external reputation as measured by external surveys and 
internal morale as measured by surveys. Finally, the value component 
included measures for underlying replacement cost profit, total cash 
costs, upstream operating cash and downstream profitability.

•	 To recommend to the board the quantum and structure of remuneration 

Mr Conn’s Refining and Marketing segment similarly included 

for the chairman of the board.

The committee operates with a high level of independence. The board 
considers all committee members to be independent (see page 121). They 
have no personal financial interest, other than as shareholders, in the 
committee’s decisions. Each member of the remuneration committee is 
subject to annual re-election as a director of the company.

Gerrit Aronson, an independent consultant, is the committee’s 
independent adviser as well as secretary. He is engaged directly by the 
committee and not by executive management. Advice is also received 
from David Jackson, the company secretary, and from the company 
secretary’s office, which is independent of executive management and 
reports to the chairman of the board. 

The committee also appoints external advisers to provide specialist advice 
and services on particular remuneration matters. The independence of 
the advice is subject to periodic review. In 2011, the committee continued 
to engage Towers Watson as its principal external adviser, primarily for 
market information. Towers Watson also provided other remuneration and 
benefits advice to parts of the group. Freshfields Bruckhaus Deringer LLP 
provided legal advice on specific matters to the committee, as well as 
providing some legal advice to the group.

The committee values its dialogue with major shareholders  
on remuneration matters. The committee is accountable to shareholders 
through its annual report on executive directors’ remuneration. It will 
consider the outcome of the vote at the AGM on the directors’ 
remuneration report and take into account the views of shareholders in its 
future decisions. 

targets for various safety measures, onstream availability, cost efficiency 
and profitability. Dr Grote’s functional segment included measures for IST 
compliance, succession and divestments.

Apart from the specific measures set out, the committee may 

consider any other results that it deems relevant and apply its judgement 
in determining final bonus scores.

Outcomes for the year are summarized in the table below, with a more 
detailed explanation following.

142    BP Annual Report and Form 20-F 2011

Directors’ remuneration reportSafety and risk management performance was strong with most targets 
exceeded. Loss of primary containment showed a 14% reduction on 
the number of incidents that occurred in the previous year and process 
safety related high potential incidents dropped 26% – both metrics 
are important indicators of process safety performance. Recordable 
injury frequency was better than target. A major change programme 
related to safety and risk management progressed very well. A central 
part of this was the completed implementation of the safety and 
operational risk function as a group-wide organization independent of line 
management. The change programme also included a major upstream 
reorganization, the introduction of a contractor management process, 
global rollout of a values and behaviours charter, implementation of a new 
individual performance and reward framework and completion of a risk 
management review.

Rebuilding trust showed some early signs of improvement but 
with clear work remaining to be done related to the long-term impact 
of the Deepwater Horizon oil spill. Independent external surveys 
reflect some recovery of trust and reputation in key markets as the 
year progressed. Internal employee alignment and morale remained 
encouragingly strong through a difficult period for the company. Employee 
satisfaction, as measured by survey, was near pre-Deepwater Horizon 
levels and a new ‘progress index’ was implemented to track specific 
employee alignment related to the company’s strategic priorities.

Rebuilding value measures were at or near target. Relative to 
target, underlying replacement cost profit was around 90% and total cash 
costs were 7% above. Upstream operating cash was some 3% better 
than target and Refining and Marketing profitability met its plan level. 
Refining and Marketing had a strong year overall with record earnings, 
good safety, and high utilization availability. 

Based on these results, the committee assessed group 

performance to be on-target. Mr Dudley therefore received a total bonus 
of 150% of salary including deferral, reflecting on-target performance. 
Mr Conn’s total bonus of 165% of salary reflected achievements above 
target for the Refining and Marketing segment. Dr Grote’s total bonus of 
150% of salary reflects on-target results at both group and function level.

Of the total bonuses referred to above, one-third is paid in cash, 

one-third is deferred on a mandatory basis and one-third is paid either 
in cash or voluntarily deferred at the individual’s discretion. Amounts, as 
received by the individuals, are shown in the table on page 141.

Deferred bonus
One-third of the total bonus awarded to the executive directors is deferred 
into shares on a mandatory basis under the terms of the deferred bonus 
element. Their deferred shares are matched on a one-for-one basis 
and will vest in three years contingent on an assessment of safety and 
environmental sustainability over the three-year deferral period. 

Individuals may elect to defer an additional one-third into shares 

on the same basis as the mandatory deferral. All three executive directors 
chose to participate in the voluntary deferral. Again this is reflected in the 
table on page 141.

All deferred bonuses will be converted to shares based on the 

average price of BP shares over the three days following the company’s 
announcement of 2011 results (£4.91/share, $46.70/ADS).

2009-2011 share element
Framework
Performance shares were awarded to each executive director in early 
2009 with vesting after three years dependent on performance relative 
to measures reflecting the company’s strategic priorities at the time. For 
the 2009 plan, vesting was based 50% on total shareholder return (TSR) 
versus the oil majors, and 50% on a balanced scorecard of underlying 
performance factors versus the same peers. The underlying performance 
factors were production growth, Refining and Marketing profitability, and 
underlying net income growth. The peer group included ExxonMobil, 
Shell, Total, Chevron and ConocoPhillips. Vesting was set at 100%, 70% 
and 35% for performance equivalent to first, second, and third rank 
respectively and none for fourth or fifth place.

Results
Reflecting the impact of the Deepwater Horizon oil spill, the TSR, 
production growth and net income growth measures for the three-year 
period 2009-2011 were all below the third place required for vesting.  
Refining and Marketing profitability was strong and based on a first 
place ranking achieved full vesting for that portion. Based on the agreed 
formula, this resulted in a vesting of 16.67% of the original award. 

The committee considered this result was a fair reflection of 
overall performance over the period. The resulting shares and value of the 
vesting is shown in the table on page 149.

2011 total remuneration outcomes
The charts below summarize the actual total remuneration outcome of 
2011 for each of the executive directors. 

The salary is the amount actually received during the year and  

the cash bonus reflects the portion of total bonus for 2011 that is  
received in cash. 

The deferred bonus reflects that portion of total bonus for 2011 

that is deferred, either on a mandatory or voluntary basis. The value 
shown is converted to shares, matched one-for-one and vests after three 
years contingent on the review of safety and environmental sustainability 
over the three years. 

Finally the share element portion reflects the value of the vesting 
that occurred for the 2009-2011 plan. These shares now enter a further 
three-year retention period before they are released to the individual.

Directors’ remuneration reportDirectors’ remuneration report Remuneration policy

This section provides information on principles underlying the company’s 
remuneration policy followed by an overview and an in-depth review of 
the policy.

Remuneration principles
Remuneration policy for executive directors is guided by key principles:
•	 Link to strategy – A substantial portion of executive remuneration 

should be linked to success in implementing the company’s business 
strategy.

•	 Performance linked – The major part of total remuneration should vary 
with performance, with the largest elements share based, further 
aligning interests with shareholders.

•	 Long-term based – The structure of pay should reflect the long-term 

nature of BP’s business and the significance of safety and 
environmental risks.

•	 Rigorous process – Performance conditions for variable pay should be 
set by the committee at the start of each year and assessed by the 
committee at the end of each performance period. Assessment should 
take into account material changes in the market environment 
(predominantly oil prices) and BP’s competitive position (primarily 
vis-à-vis other oil majors).

The chart below shows the range of results possible for the group chief 
executive depending on performance outcomes. 

The on-target column assumes one-third of total bonus is deferred 

and matched, and the share element is valued at half the award. 

The maximum column assumes that two-thirds of the total bonus 

is deferred and matched, and full vesting of the share element.

•	 Informed judgement – There should be both quantitative and qualitative 
assessments of performance with the committee making an informed 
judgement within a framework approved by shareholders.

Remuneration is strongly performance dependent:
•	 Bonus based on metrics from annual plan.
•	 Deferred bonus vesting based on additional safety and environment 

sustainability assessment.

•	 Share element based on metrics reflecting strategic priorities.

It is also heavily weighted towards the long term:
•	 Deferred bonus – three years.
•	 Share element – six years.

•	 Fair treatment – The committee reviews the pay policy and levels for 
executives below board, as well as pay and conditions of employees 
throughout the group. These are considered when determining 
executive directors’ remuneration. Salaries should be reviewed annually, 
in the context of the total quantum of pay, and taking into account both 
external market and internal company conditions.

•	 Personal shareholding – Executives should develop and be required to 
hold a significant shareholding as this represents the best way to align 
their interests with those of shareholders.

•	 Shareholder engagement – The remuneration committee will actively 
seek to understand shareholder preferences and be transparent in 
explaining its remuneration policy and practices.

These principles result in a remuneration policy that is directly linked to 
strategy, strongly performance related and heavily weighted towards long 
term.

Pension and other 
benefits

Executive directors should participate in the normal pension and 
benefit schemes applying in their home countries. 

Both UK and US executive directors remain on defined benefit 
pension plans reflecting respective national norms. UK 
directors, as for all UK employees who exceed the annual 
allowance set by legislation, may receive a cash supplement in 
lieu of future service pension accrual.

Variable remuneration
Annual bonus

Annual bonus should be based on performance relative to 
measures and targets reflecting the annual plan. 

Bonus measures for 2012 are:
•	 Safety and risk management (30%).

Achieving plan results should equate to on-target bonus.
On-target bonus is set at 150% of salary for executive directors 
with a maximum of 225% of salary.

Deferred bonus

A portion of annual bonus should be paid in shares and deferred 
to add long-term sustainability and shareholder alignment to 
short-term performance achievement.

One-third of annual bonus is deferred on a mandatory basis and 
a further one-third can be deferred on a voluntary basis.

Performance 
shares

A large portion of total remuneration for executive directors 
should be tied to the long-term performance of the company.

Shares to a value of 5.5 times salary for the group chief 
executive and 4 times salary for the other executive directors 
are normally awarded annually.

Vesting of the shares after three years is dependent on 
performance relative to measures reflecting the strategic 
priorities of the company.

Those shares that vest are held for an additional three-year 
retention period, after payment of tax on vesting.

Executive directors should develop significant personal 
shareholding in order to align their interests with shareholders.

All deferred shares are matched on a one-for-one basis.

All deferred and matched shares vest after three years 
contingent on an assessment of safety and environmental 
sustainability over the three-year deferral period.

The 2012-2014 share element will vest based equally on the 
following three performance metrics:
•	 Total shareholder return versus oil majors.
•	 Operating cash flow.
•	 Strategic imperatives.

Executive directors are required to develop, and maintain, a 
shareholding equivalent to five times salary, within a reasonable 
time of appointment.

BP Annual Report and Form 20-F 2011    145

Directors’ remuneration reportDirectors’ remuneration report In all cases, targets for each measure are set so that achieving plan 
levels of performance equates to an on-target bonus. As in past years, 
in addition to the specific bonus metrics, the committee will also review 
the underlying performance of the group in light of competitors’ results, 
analysts’ reports and the views of the chairmen of the other committees. 
Based on this broader view, the committee can decide to adjust bonuses 
where it is warranted and, in exceptional circumstances, to pay no 
bonuses.

Deferred bonus
The structure of deferred bonus, paid in shares, places increased focus 
on long-term alignment with shareholders, and reinforces the critical 
importance of maintaining high safety and environmental standards. It 
effectively translates the outcome of a portion of the annual performance 
bonus into a long-term plan with additional performance hurdles. As 
shown below, the results of 2012 will form the basis for determining the 
deferred bonus in 2013.

2016

For 2012, as last year, one-third of the annual bonus will be deferred 
into shares for three years and matched by the company on a one-for-
one basis. Under the rules of the plan, the average share price over 
the three days following announcement of full-year results is used to 
determine the number of shares. Both deferred and matched shares 
will vest in February 2016 contingent on an assessment of safety and 
environmental sustainability over the three-year deferral period. If the 
committee assesses that there has been a material deterioration in safety 
and environmental metrics, or there have been major incidents revealing 
underlying weaknesses in safety and environmental management, then it 
may conclude that shares should vest in part, or not at all. In reaching its 
conclusion, the committee will obtain advice from the safety, ethics and 
environment assurance committee (SEEAC).

Executive directors may voluntarily defer a further one-third of their 
annual bonus into shares, which will be capable of vesting, and will qualify 
for matching, on the same basis as set out above. Where shares vest, 
the executive director will also receive additional shares representing the 
value of the re-invested dividends.

Performance shares
The performance share element reflects the committee’s policy that a 
large proportion of total remuneration is tied to long-term performance. 
Performance shares are awarded at the start of each year and vesting, 
after three years, is based on performance relative to measures and 
targets derived from the company’s strategic priorities. Those shares 
that vest are then held for a further three-year retention period before 
being released to the executive after payment of tax on vesting. 
This gives executive directors a six-year incentive structure, which is 
designed to ensure their interests are aligned with those of shareholders. 
Where shares vest, the executive director will receive additional shares 
representing the value of the re-invested dividends.

Remuneration policy for 2012 in more depth
This section contains a more detailed explanation of the components of  
total remuneration for executive directors and how they will be 
implemented in 2012.

Salary
The committee normally reviews salaries annually, taking into account 
other large Europe-based global companies, other oil majors, and relevant 
US companies. It also considers salary treatment throughout the company 
when determining appropriate increases for executive directors.

Annual bonus
The group strategy provides the context for the company’s annual plan, 
from which measures and targets are derived at the start of the year for 
senior managers including executive directors. Measures typically include 
a range of financial and operating metrics as well as those relating to 
safety and environment, and people.

At the end of each year, performance is assessed relative to the 

measures and targets established at the start of the year, adjusted for any 
material changes in the market environment (predominantly oil prices).  
Assessment includes both quantitative and qualitative views as well as 
input from the other committees on relevant aspects. The committee 
considers that this informed judgement is important to establishing a fair 
overall assessment.  

The chart below shows the average annual bonus result (before 
any deferral) and relative to an on-target level for executive directors for 
the current year and previous five.

average actual result

For 2012, all executive directors will again be eligible for a total bonus 
(including deferral) of 150% of salary at target and 225% at maximum. 
Mr Dudley’s bonus will be based entirely on group measures. Mr Conn, 
Dr Gilvary and Dr Grote will have 70% of their bonus based on group 
results and 30% on their respective segment or function.

The measures used to determine bonus results flow directly from 
the group’s annual plan which reflects the strategic priorities of reinforcing 
safety and risk management, rebuilding trust, and reinforcing value 
creation. 

At group level, safety and risk management measures include 
recordable injury frequency, loss of primary containment and process 
related major incident announcements and high potential incidents. 
Rebuilding trust will be measured via surveys to assess both external 
reputation and internal staff alignment and morale. Restoring value will 
provide the dominant set of measures and include operating cash flow, 
underlying replacement cost profit, total cash costs, gearing, divestments, 
upstream production efficiency, major project delivery and Refining and 
Marketing profitability.

The Refining and Marketing segment will include specific safety 

metrics for the segment. Value metrics will include availability, efficiency, 
and profitability metrics, as well as divestments and major project 
delivery. Finance function measures will include divestments, gearing 
and major project delivery. The corporate business function will include 
profitability and compliance measures for IST and Alternative Energy.

The maximum number of shares that can be awarded will be 5.5 times 
salary for the group chief executive and 4 times salary for the other 
executive directors. Performance shares will only vest to the extent that 
performance conditions, as described below, are met and subject to the 
committee concluding that this is appropriate. The history of vesting of 
the share element is shown below.

Performance conditions
Performance conditions for the 2012-2014 share element will be aligned 
with the company’s strategic agenda which continues to focus on value 
creation, reinforcing safety and risk management, and rebuilding trust. 
Vesting of shares will be based one-third on BP’s total shareholder return 
(TSR) compared to the other oil majors, reflecting the central importance 
of restoring the value of the company. A further one-third will be based 
on the operating cash flow of the company, reflecting a central element 
of value creation. The final one-third will be based on a set of strategic 
imperatives; in particular, reserves replacement, process safety, and 
rebuilding trust. 

For the relative measures, TSR and the reserves replacement ratio, 
the comparator group will consist of ExxonMobil, Shell, Total and Chevron. 
This group can be altered if circumstances change, for example, if there is 
significant consolidation in the industry. While a narrow group, it continues 
to represent the comparators that both shareholders and management 
use in assessing relative performance. 

The TSR will be calculated as the share price performance over 

the three-year period, assuming dividends are re-invested. All share prices 
will be averaged over the three-month period before the beginning and 
end of the performance period. They will be measured in US dollars. 
The reserves replacement ratio is defined according to industry standard 
specifications and its calculation is audited. As in previous years, the 
methodology used for the relative measures will rank each of the five 
oil majors on each measure. Performance shares for each component 
will vest at levels of 100%, 70% and 35% respectively, for performance 
equivalent to first, second and third rank. No shares will vest for fourth or 
fifth place. 

Operating cash flow has been identified as a core strategic priority 

of the company. As has been communicated publicly, the target is to 
grow operating cash flow to $33 billion by 2014 based on $100/bbl oil 
price assumption. Below $31 billion, there will be no vesting under this 
component. Between $31 billion and $35 billion there will be a straight 
line vesting from 60% to 100% respectively. 

Finally the remaining strategic imperatives relating to process 
safety and rebuilding trust will be determined by a mixture of internal 
targets and external assessment. In the case of process safety, high 
potential incidents and major incident announcements will provide 
the key factual data as well as the input of the SEEAC. The rebuilding 
trust component will include both external and internal surveys that 
will be used by the committee, along with input from the other board 
committees, to judge performance. The results will be explained in 
subsequent directors’ remuneration reports.

The committee considers that this combination of quantitative 

and qualitative measures reflects the long-term value creation priorities of 
the company as well as the key underpinnings for business sustainability. 
As in previous years, the committee may exercise its discretion, in a 
reasonable and informed manner, to adjust vesting levels upwards or 
downwards if it concludes that the formulaic approach does not reflect 
the true underlying health and performance of BP’s business relative to its 

peers. It will explain any adjustments in the directors’ remuneration report 
following vesting, in line with its commitment to transparency. 

Shareholding policy
The committee’s policy, reflected in the Executive Directors’ Incentive 
Plan (EDIP), continues to be that each executive director builds and 
maintains a significant personal shareholding in BP to create strong 
alignment with shareholders. Executive directors, under the policy, are 
required to build a share base equating to five times salary, within a 
reasonable time from their appointment. Each director’s shareholding as 
at 31 December 2011 is set out on page 117.

BP Annual Report and Form 20-F 2011    147

Directors’ remuneration reportDirectors’ remuneration report  
 
 
Pensions
Executive directors are eligible to participate in the appropriate pension 
schemes applying in their home countries. Details are set out in the 
table below.

UK directors
UK directors are members of the regular BP pension scheme. The core 
benefits under this scheme are non-contributory. They include a pension 
accrual of 1/60th of basic salary for each year of service, up to a maximum 
of two-thirds of final basic salary and a dependant’s benefit of two-thirds of 
the member’s pension. The scheme pension is not integrated with state 
pension benefits.

The rules of the BP pension scheme were amended in 2006 such 
that the normal retirement age is 65. Prior to 1 December 2006, scheme 
members could retire on or after age 60 without reduction. Special early 
retirement terms apply to pre-1 December 2006 service for members with 
long service as at 1 December 2006.

Until the end of March 2011, pension benefits in excess of the 
individual lifetime allowance set by legislation were paid via an unapproved, 
unfunded pension arrangement provided directly by the company.

With the reduction in the annual allowance applicable to plans such 

as the BP pension scheme in 2011 the company reviewed the options 
available for employees who might wish to limit the increase in the value of 
their pension to remain within the new limit. To provide employees with 
flexibility, should they wish to limit the value of the increase in their 
pension to within the new limit, those impacted are able to elect a lower 
accrual rate and in addition receive a cash supplement so that the total cost 
to BP remains equivalent to the cost of providing 1/60th of basic salary. 
Some employees have had to cease pension accrual for future service to 
remain within the new annual allowance. For these employees the cash 
supplement is equal to 35% of basic salary.

Mr Conn has elected to cease to accrue pension benefits for future 
service in order to keep within the new annual allowance and has received 
a cash supplement of 35% of his basic salary from 1 April 2011. This is 
included in the remuneration table on page 141.

US directors
Mr Dudley and Dr Grote participate in the US BP retirement accumulation 
plan (US pension plan), which features a cash balance formula. Pension 
benefits are provided through a combination of tax-qualified and 
non-qualified benefit restoration plans, consistent with US tax regulations 
as applicable. 

BP also provides a supplemental executive retirement benefits plan 

(supplemental plan), which is a non-qualified arrangement that became 
effective on 1 January 2002 for US employees with salary above a 
specified salary grade level. Mr Dudley and Dr Grote are eligible to 
participate under the supplemental plan. The benefit formula is a target of 
1.3% of final average earnings (base pay plus bonus) for each year of 
service, inclusive of all other BP (US) qualified and non-qualified pension 
arrangements. This benefit is unfunded and therefore paid from corporate 
assets.

Mr Dudley retains the heritage Amoco retirement plan, which 
provides benefits on a final average pay formula of 1.67% of highest 
average earnings (base pay plus bonus in accordance with standard US 
practice) for each year of service, reduced by 1.5% of the primary social 
security benefit for each year of service. The highest benefit of the plans 
produced by the different formulas will be payable and this is currently the 
benefit determined under the Amoco heritage terms.

Their pension accrual for 2011, shown in the table below, takes into 

account the total amount that could be payable under relevant plans.

Other benefits
Executive directors are eligible to participate in regular employee benefit 
plans and in all-employee share saving schemes applying in their home 
countries. Benefits in kind are not pensionable.

 a BP’s performance is measured against the oil sector. For awards under the 2009-2011 plan, performance conditions are measured 50% on TSR against ExxonMobil, Shell, Total, ConocoPhillips and 
Chevron and 50% on a balanced scorecard of underlying performance. For the awards under the 2010-2012 plan, performance conditions are measured one third on TSR against ExxonMobil, Shell, Total, 
ConocoPhillips and Chevron and two thirds on a balanced scorecard of underlying performance. For awards under 2011-2013 plan, performance conditions are measured 50% on TSR against ExxonMobil, 
Shell, Total, ConocoPhillips and Chevron; 20% on reserves replacement against the same peer group; and 30% against a balanced scorecard of strategic imperatives. Each performance period ends on 
31 December of the third year.
 b Represents vestings of shares made at the end of the relevant performance period based on performance achieved under rules of the plan and includes re-invested dividends on the shares vested.
 c Dr Grote and Mr Dudley receive awards in the form of ADSs. The above numbers reflect calculated equivalents in ordinary shares.

Service contracts

Executive directors – external appointments

Service contracts have a notice period of one year and may be terminated 
by the company at any time with immediate effect on payment in lieu of 
notice equivalent to one year’s salary or the amount of salary that would 
have been paid if the contract had been terminated on the expiry of the 
remainder of the notice period. Other than in the case of Dr Gilvary (who 
became a director on 1 January 2012), the service contracts are expressed 
to expire at a normal retirement age of 60 (subject to age discrimination).

The board encourages executive directors to broaden their knowledge and 
experience by taking up appointments outside the company. Each 
executive director is permitted to accept one non-executive appointment, 
from which they may retain any fee. External appointments are subject to 
agreement by the chairman and reported to the board. Any external 
appointment must not conflict with a director’s duties and commitments 
to BP.

which expires on 15 April 2012. Dr Grote’s contract is with BP Exploration 
(Alaska) Inc. He is seconded to BP p.l.c. under a secondment agreement 
of 7 August 2000, which expires at the date of the 2013 AGM. Both 
secondments can be terminated by one month’s notice by either party and 
terminate automatically on the termination of their service contracts.

There are no other provisions for compensation payable on early 

termination of the above contracts. In the event of the early termination of 
any of the contracts by the company, other than for cause (or under a 
specific termination payment provision), the relevant director’s then current 
salary and benefits would be taken into account in calculating any liability of 
the company. The committee will consider mitigation to reduce 
compensation to a departing director, when appropriate to do so.

150    BP Annual Report and Form 20-F 2011

Directors’ remuneration reportNon-executive directors’ 
remuneration
Policy

The board sets the level of remuneration for all non-executive directors 
within a limit approved from time to time by shareholders. Key elements of 
BP’s policy on non-executive director remuneration include:
•	 Remuneration should be sufficient to attract, motivate and retain 

world-class non-executive talent.

•	 Remuneration of non-executive directors is proposed by the chairman 

of the board and agreed by the board and should be proportional to their 
contribution towards the interests of the company.

•	 Remuneration practice should be consistent with recognized best 

practice standards for non-executive directors’ remuneration.

•	 Remuneration should be in the form of cash fees, payable monthly.
•	 Non-executive directors should not receive share options from the 

company.

•	 Non-executive directors are encouraged to establish a holding in BP 

shares of the equivalent value of one-year’s base fee.

Process

BP reviews the quantum and structure of chairman of the board and 
non-executive remuneration on an annual basis. The chairman’s 
remuneration is reviewed by the remuneration committee, who makes a 
recommendation to the board; the chairman does not vote on his own 
remuneration. Non-executive director remuneration is reviewed by the 
chairman, who makes a recommendation to the board; non-executive 
directors do not vote on their own remuneration.

Following the 2011 review of non-executive remuneration, it was 

concluded that in light of wider economic circumstances, an increase 
would not be appropriate and therefore no adjustment would be made to 
fee levels. It was agreed that the policy of annual review would continue 
and that the transatlantic attendance allowance be renamed the 
intercontinental travel allowance to better reflect when the allowance 
is awarded.

Fee structure

The table below shows the current fee structure for non-executive 
directors on 1 January 2012:

 a In addition, George David received a £28,000 fee for chairing the BP technical advisory council.
 b Appointed on 1 February 2011.
 c This figure excludes a superannuation gratuity of £1,543.

While fees were held at 2010 levels, in 2011 actual fees paid to 
non-executive directors were affected by changes in chairmanship and 
committee membership and the number of intercontinental meetings for 
which an attendance allowance was paid.

No share or share option awards were made to any non-executive 

director in respect of service on the board during 2011.

Non-executive directors have letters of appointment which 
recognize that, subject to the Articles of Association, their service is at the 
discretion of shareholders. All directors stand for re-election at each AGM.

Superannuation gratuities

Until 2002, BP maintained a long-standing practice whereby non-executive 
directors who retired from the board after at least six years’ service were 
eligible for consideration for a superannuation gratuity. The board was, and 
continues to be, authorized to make such payments under the company’s 
Articles of Association and the amount of the payment is determined at the 
board’s discretion, taking into consideration the director’s period of service 
and other relevant factors.

In 2002, the board revised its policy with respect to superannuation 

gratuities so that:
•	 Non-executive directors appointed to the board after 1 July 2002 would 

not be eligible for consideration for such a payment.

•	 While non-executive directors in service at 1 July 2002 would remain 
eligible for consideration for a payment, service after that date would 
not be taken into account by the board in considering the amount of any 
such payment.

Dr DeAnne Julius who retired on 14 April 2011 was paid a superannuation 
gratuity of £1,543, in line with the policy arrangements agreed in 2002 and 
outlined above. With the retirement of Dr Julius from the board, no other 
non-executive directors are eligible for superannuation gratuities.

Past directors

Sir Ian Prosser (who retired as a non-executive director of BP in April 2010) 
was appointed as a director and non-executive chairman of BP Pension 
Trustees Limited on 29 September 2010. During 2011, he received 
£100,000 for this role.

Peter Sutherland (who was chairman of BP until 31 December 

2009) continued his membership of the BP international advisory board 
after his retirement from the board of BP p.l.c. During 2011, he received 
e100,000 for this role.

This directors’ remuneration report was approved by the board and signed 
on its behalf by David J Jackson, Company Secretary on 6 March 2012.

 Additional information for shareholdersCritical accounting policies

The significant accounting policies of the group are summarized in Financial 
statements – Note 1 on pages 182-189.

Inherent in the application of many of the accounting policies used 

in preparing the financial statements is the need for BP management to 
make judgements, estimates and assumptions that affect the reported 
amounts of assets and liabilities at the date of the financial statements and 
the reported amounts of revenues and expenses during the period. Actual 
outcomes could differ from the estimates and assumptions used. The 
following summary provides more information about the critical accounting 
judgements and estimates that could have a significant impact on the 
results of the group and should be read in conjunction with the information 
provided in the Notes on financial statements, including Note 1 Significant 
accounting policies.

The areas requiring the most significant judgement and estimation 

in the preparation of the consolidated financial statements are in relation 
to oil and natural gas accounting, including the estimation of reserves, the 
recoverability of asset carrying values, business combinations, taxation, 
derivative financial instruments, provisions and contingencies, and in 
particular, provisions and contingencies related to the Gulf of Mexico oil 
spill, and pensions and other post-retirement benefits.

Oil and natural gas accounting
The group follows the principles of the successful efforts method 
of accounting for its oil and natural gas exploration, appraisal and 
development expenditure. The group’s accounting policy for oil and natural 
gas exploration, appraisal and development expenditure is provided in 
Financial statements – Note 1 on page 184.

The accounting for oil and natural gas exploration, appraisal and 
development expenditure requires the use of various judgements and 
estimates in management’s determination of the economic viability of a 
project based on a range of technical and commercial considerations, the 
establishment of development plans and timing, and estimates of future 
expenditure.

Exploration licence and leasehold property acquisition costs are 

capitalized within intangible assets and are reviewed at each reporting date 
to confirm that there is no indication that the carrying amount exceeds 
the recoverable amount. This review includes confirming that exploration 
drilling is still under way or firmly planned or that it has been determined, 
or work is under way to determine, that the discovery is economically 
viable based on a range of technical and commercial considerations and 
sufficient progress is being made on establishing development plans and 
timing. If no future activity is planned, the remaining balance of the licence 
and property acquisition costs is written off. Lower value licences are 
pooled and amortized on a straight-line basis over the estimated period of 
exploration.

For exploration wells and exploratory-type stratigraphic test wells, 

costs directly associated with the drilling of wells are initially capitalized 
within intangible assets, pending determination of whether potentially 
economic oil and gas reserves have been discovered by the drilling effort. 
These costs include employee remuneration, materials and fuel used, rig 
costs, delay rentals and payments made to contractors. The determination 
is usually made within one year after well completion, but can take longer, 
depending on the complexity of the geological structure. If the well did 
not encounter potentially economic oil and gas quantities, the well costs 
are expensed as a dry hole and are reported in exploration expense. 
Exploration wells that discover potentially economic quantities of oil and 
natural gas and are in areas where major capital expenditure (e.g. offshore 
platform or a pipeline) would be required before production could begin, 
and where the economic viability of that major capital expenditure depends 
on the successful completion of further exploration work in the area, 
remain capitalized on the balance sheet as long as additional exploration 
appraisal work is under way or firmly planned.

It is not unusual to have exploration wells and exploratory-type stratigraphic 
test wells remaining suspended on the balance sheet for several years 
while additional appraisal drilling and seismic work on the potential oil and 
natural gas field is performed or while the optimum development plans and 
timing are established.

All such carried costs are subject to regular technical, commercial 

and management review on at least an annual basis to confirm the 
continued intent to develop, or otherwise extract value from, the discovery. 
Where this is no longer the case, the costs are immediately expensed.

The determination of the group’s estimated oil and gas reserves 

requires significant judgements and estimates to be applied and these 
are regularly reviewed and updated. Factors such as the availability of 
geological and engineering data, reservoir performance data, acquisition 
and divestment activity, drilling of new wells and commodity prices all 
impact on the determination of the group’s estimates of its oil and gas 
reserves. BP bases its proved reserves estimates on the requirement of 
reasonable certainty with rigorous technical and commercial assessments 
based on conventional industry practice.

The estimation of oil and natural gas reserves and BP’s process 
to manage reserves bookings is described in Exploration and Production 
– Oil and gas disclosures on page 89, which is unaudited. Details on BP’s 
proved reserves and production compliance and governance processes are 
provided on pages 90-91.

Estimates of oil and gas reserves are used to calculate depreciation, 

depletion and amortization charges for the group’s oil and gas properties. 
The impact of changes in estimated proved reserves is dealt with 
prospectively by amortizing the remaining carrying value of the asset over 
the expected future production. As discussed below, oil and natural gas 
reserves also have a direct impact on the assessment of the recoverability 
of asset carrying values reported in the financial statements.

If proved reserves estimates are revised downwards, earnings 

could be affected by higher depreciation expense or an immediate write-
down of the property’s carrying value (see discussion of recoverability of 
asset carrying values below).

The 2011 movements in proved reserves are reflected in the 

tables showing movements in oil and gas reserves by region in Financial 
statements – Supplementary information on oil and natural gas (unaudited) 
on pages 259-281. Information on the carrying amounts of the group’s oil 
and gas properties, together with the amounts recognized in the income 
statement as depreciation, depletion and amortization is contained in 
Financial statements – Note 15 and Note 9 respectively.

Recoverability of asset carrying values
BP assesses its fixed assets, including goodwill, for possible impairment 
if there are events or changes in circumstances that indicate that carrying 
values of the assets may not be recoverable and, as a result, charges for 
impairment are recognized in the group’s results from time to time, with 
corresponding reductions in the carrying values of the group’s assets. 
Such indicators include changes in the group’s business plans, changes 
in commodity prices leading to sustained unprofitable performance, an 
increase in the discount rate, low plant utilization, evidence of physical 
damage and, for oil and natural gas properties, significant downward 
revisions of estimated volumes or increases in estimated future 
development expenditure. If there are low oil prices, natural gas prices, 
refining margins or marketing margins during an extended period, the 
group may need to recognize significant impairment charges.

The assessment for impairment entails comparing the carrying 
value of the asset or cash-generating unit with its recoverable amount, 
that is, the higher of fair value less costs to sell and value in use. Value 
in use is usually determined on the basis of discounted estimated future 
net cash flows. Determination as to whether and how much an asset is 
impaired involves management estimates on highly uncertain matters such 
as future commodity prices, the effects of inflation on operating expenses, 
discount rates, production profiles and the outlook for global or regional 
market supply-and-demand conditions for crude oil, natural gas and refined 
products.

154    BP Annual Report and Form 20-F 2011

Additional information for shareholdersFor oil and natural gas properties, the expected future cash flows are 
estimated using management’s best estimate of future oil and natural 
gas prices and reserves volumes. Prices for oil and natural gas used for 
future cash flow calculations are based on market prices for the first 
five years and the group’s long-term price assumptions thereafter. As at 
31 December 2011, the group’s long-term price assumptions were $90 
per barrel for Brent and $6.50/mmBtu for Henry Hub (2010 $75 per barrel 
and $6.50/mmBtu). These long-term price assumptions are subject to 
periodic review and modification. The estimated future level of production 
is based on assumptions about future commodity prices, production 
and development costs, field decline rates, current fiscal regimes and 
other factors.

The future cash flows are adjusted for risks specific to the cash-

generating unit and are discounted using a pre-tax discount rate. The 
discount rate is derived from the group’s post-tax weighted average 
cost of capital and is adjusted where applicable to take into account any 
specific risks relating to the country where the cash-generating unit is 
located, although other rates may be used if appropriate to the specific 
circumstances. In 2011 the rates ranged from 12% to 14% nominal  
(2010 11% to 14% nominal). The rate applied in each country is  
reassessed each year.

Irrespective of whether there is any indication of impairment, BP is 
required to test annually for impairment of goodwill acquired in a business 
combination. The group carries goodwill of approximately $12.1 billion 
on its balance sheet (2010 $8.6 billion), principally relating to the Atlantic 
Richfield, Burmah Castrol, Devon Energy and Reliance transactions. In 
testing goodwill for impairment, the group uses a similar approach to that 
described above for asset impairment. If there are low oil prices or natural 
gas prices or refining margins or marketing margins for an extended period, 
the group may need to recognize significant goodwill impairment charges. 
In 2009, an impairment loss of $1.6 billion was recognized to write off all 
of the goodwill allocated to the US West Coast fuels value chain (FVC). 
The prevailing weak refining environment, together with a review of future 
margin expectations in the FVC, led to a reduction in the expected future 
cash flows.

Refer to Oil and natural gas accounting above for a discussion on 

the recoverability of intangible exploration and appraisal expenditure.

Details of impairment charges recognized in the income statement 

are provided in Financial statements – Note 5 and details on the carrying 
amounts of assets are shown in Financial statements – Note 21, Note 22 
and Note 23.

Business combinations
Accounting for business combinations using the acquisition method 
requires the determination of the fair value of the consideration transferred, 
together with the fair value of the identifiable assets acquired and liabilities 
assumed at the acquisition date. Goodwill is measured as being the excess 
of the aggregate of the consideration transferred, the amount recognized 
for any minority interest and the acquisition-date fair values of any 
previously held interest in the acquiree over the fair value of the identifiable 
assets acquired and liabilities assumed at the acquisition date.

Judgement is required in determining whether a transaction meets 

the criteria to be treated as a business combination or not. Judgements 
and estimates are also required in order to determine the fair values of the 
assets acquired and the liabilities assumed, and the group uses all available 
information, including external valuations and appraisals where appropriate, 
to determine these fair values. If necessary, the group has up to one year 
from the acquisition date to finalize the determinations of fair value.

Details of the business combinations undertaken by the group in 

2011 are provided in Financial statements – Note 3 on page 194.

Taxation
The computation of the group’s income tax expense and liability 
involves the interpretation of applicable tax laws and regulations in many 
jurisdictions throughout the world. The resolution of tax positions taken 
by the group, through negotiations with relevant tax authorities or through 
litigation, can take several years to complete and in some cases it is 
difficult to predict the ultimate outcome.

In addition, the group has carry-forward tax losses and tax credits in 
certain taxing jurisdictions that are available to offset against future taxable 
profit. However, deferred tax assets are recognized only to the extent 
that it is probable that taxable profit will be available against which the 
unused tax losses or tax credits can be utilized. Management judgement is 
exercised in assessing whether this is the case.

To the extent that actual outcomes differ from management’s 
estimates, income tax charges or credits, and changes in deferred tax 
assets or liabilities, may arise in future periods. For more information see 
Financial statements – Note 18 on page 210 and Note 43 on page 249.

Derivative financial instruments
The group uses derivative financial instruments to manage certain 
exposures to fluctuations in foreign currency exchange rates, interest 
rates and commodity prices as well as for trading purposes. In addition, 
derivatives embedded within other financial instruments or other host 
contracts are treated as separate derivatives when their risks and 
characteristics are not closely related to those of the host contract. All 
such derivatives are initially recognized at fair value on the date on which a 
derivative contract is entered into and are subsequently remeasured at fair 
value. Gains and losses arising from changes in the fair value of derivatives 
that are not designated as effective hedging instruments are recognized in 
the income statement.

In some cases the fair values of derivatives are estimated using 

internal models and other valuation methods due to the absence of quoted 
prices or other observable, market-corroborated data. This applies to the 
group’s longer-term, structured derivative products and complex options, 
as well as to the majority of the group’s natural gas embedded derivatives. 
The group’s embedded derivatives arise primarily from long-term UK gas 
contracts that use pricing formulae not related to gas prices, for example, 
oil product and power prices. These contracts are valued using models 
with inputs that include price curves for each of the different products that 
are built up from active market pricing data and extrapolated to the expiry 
of the contracts using the maximum available external pricing information. 
Additionally, where limited data exists for certain products, prices are 
interpolated using historic and long-term pricing relationships. Price 
volatility is also an input for the models.

Changes in the key assumptions could have a material impact on 
the fair value gains and losses on derivatives and embedded derivatives 
recognized in the income statement. For more information see Financial 
statements – Note 33 on page 224.

Details of the value-at-risk techniques used by the group to 
measure market risk exposure arising from its derivative trading positions 
is provided in Financial statements – Note 26 on page 217. An analysis of 
the sensitivity of the fair value of the embedded derivatives to changes 
in the key assumptions is provided in Financial statements – Note 26 on 
page 217.

natural gas production facilities and pipelines at the end of their economic 
lives. The largest decommissioning obligations facing BP relate to the 
plugging and abandonment of wells and the removal and disposal of oil 
and natural gas platforms and pipelines around the world. The estimated 
discounted costs of performing this work are recognized as we drill the 
wells and install the facilities, reflecting our legal obligations at that time. 
A corresponding asset of an amount equivalent to the provision is also 
created within property, plant and equipment. This asset is depreciated 
over the expected life of the production facility or pipeline. Most of these 
decommissioning events are many years in the future and the precise 
requirements that will have to be met when the removal event actually 
occurs are uncertain. Decommissioning technologies and costs are 
constantly changing, as well as political, environmental, safety and public 
expectations. Consequently, the timing and amounts of future cash flows 
are subject to significant uncertainty. Any changes in the expected future 
costs are reflected in both the provision and the asset.

Decommissioning provisions associated with downstream and 
petrochemicals facilities are generally not recognized, as such potential 
obligations cannot be measured, given their indeterminate settlement 
dates. The group performs periodic reviews of its downstream 
and petrochemicals long-lived assets for any changes in facts and 
circumstances that might require the recognition of a decommissioning 
provision.

The timing and amount of future expenditures are reviewed 
annually, together with the interest rate used in discounting the cash flows. 
The interest rate used to determine the balance sheet obligation at the end 
of 2011 was 0.5% (2010 1.5%). The interest rate represents the real rate 
(i.e. excluding the impacts of inflation) on long-dated government bonds.
Other provisions and liabilities are recognized in the period when 
it becomes probable that there will be a future outflow of funds resulting 
from past operations or events and the amount of cash outflow can 
be reliably estimated. The timing of recognition and quantification of 
the liability require the application of judgement to existing facts and 
circumstances, which can be subject to change. Since the actual cash 
outflows can take place many years in the future, the carrying amounts 
of provisions and liabilities are reviewed regularly and adjusted to take 
account of changing facts and circumstances.

A change in estimate of a recognized provision or liability would 

result in a charge or credit to net income in the period in which the change 
occurs (with the exception of decommissioning costs as described above).
Provisions for environmental remediation are made when a 

clean-up is probable and the amount of the obligation can be reliably 
estimated. Generally, this coincides with commitment to a formal plan 
of action or, if earlier, on divestment or on closure of inactive sites. The 
provision for environmental liabilities is estimated based on current legal 
and constructive requirements, technology, price levels and expected 
plans for remediation. Actual costs and cash outflows can differ from 
estimates because of changes in laws and regulations, public expectations, 
prices, discovery and analysis of site conditions and changes in clean-up 
technology.

The provision for environmental liabilities is reviewed at least 
annually. The interest rate used to determine the balance sheet obligation 
at 31 December 2011 was 0.5% (2010 1.5%).

Information about the group’s provisions is provided in Financial 

statements – Note 36.

As further described in Financial statements – Note 43 on page 249, 

the group is subject to claims and actions. The facts and circumstances 
relating to particular cases are evaluated regularly in determining whether 
it is probable that there will be a future outflow of funds and, once 
established, whether a provision relating to a specific litigation should be 
established or revised. Accordingly, significant management judgement 
relating to provisions and contingent liabilities is required, since the 
outcome of litigation is difficult to predict.

Gulf of Mexico oil spill
Detailed information on the Gulf of Mexico oil spill, including the financial 
impacts, is provided in Financial statements – Note 2 on pages 190-194.
As a consequence of the Gulf of Mexico oil spill, as described on 

pages 76-79, BP continues to incur costs and has also recognized liabilities 
for future costs. Liabilities of uncertain timing or amount and contingent 
liabilities have been accounted for and/or disclosed in accordance with IAS 
37 ‘Provisions, contingent liabilities and contingent assets’. BP’s rights and 
obligations in relation to the $20-billion trust fund which was established 
in 2010 are accounted for in accordance with IFRIC 5 ‘Rights to interests 
arising from decommissioning, restoration and environmental rehabilitation 
funds’.

The total amounts that will ultimately be paid by BP in relation to all 
obligations relating to the incident are subject to significant uncertainty and 
the ultimate exposure and cost to BP will be dependent on many factors 
(including, with respect to certain of the obligations, any determination of 
BP’s culpability based on any findings of negligence, gross negligence or 
wilful misconduct). Furthermore, significant uncertainty exists in relation to 
the amount of claims that will become payable by BP, the amount of fines 
that will ultimately be levied on BP, the outcome of litigation and arbitration 
proceedings, the amount and timing of payments under any settlements, 
and any costs arising from any longer-term environmental consequences 
of the oil spill, which will also impact upon the ultimate cost for BP. Any 
further settlements which may be reached relating to the Deepwater 
Horizon oil spill could impact the amount and timing of any future 
payments. Although the provision recognized is the current best reliable 
estimate of expenditures required to settle certain present obligations at 
the end of the reporting period, there are future expenditures for which 
it is not possible to measure the obligation reliably as noted below under 
Contingent liabilities.

The magnitude and timing of possible obligations in relation to the 

Gulf of Mexico oil spill are subject to a very high degree of uncertainty 
as described further in Risk factors on pages 59-63. Furthermore, other 
material unanticipated obligations may arise in future in relation to the 
incident. Refer to Financial statements – Note 43 on page 249 for further 
information.

Expenditure to be met from the $20-billion trust fund
In 2010, BP established the Deepwater Horizon Oil Spill Trust (the Trust) to 
be funded in the amount of $20 billion over the period to the fourth quarter 
of 2013, which is available to satisfy legitimate individual and business 
claims administered by the Gulf Coast Claims Facility (GCCF), state and 
local government claims resolved by BP, final judgments and settlements, 
state and local response costs, and natural resource damages and related 
costs. It is currently expected that the cost of the proposed settlement 
will be payable from the Trust. In 2010, BP contributed $5 billion to the 
fund, and further regular contributions totalling $5 billion were made in 
2011. During 2011, BP also contributed the cash settlements received 
from MOEX, Weatherford and Anadarko amounting in total to $5.1 billion. 
A further cash settlement from Cameron was received in January 2012 
and was also contributed to the trust fund. As a result of these accelerated 
contributions, it is now expected that the $20-billion commitment will have 
been paid in full by the end of 2012.

Fines, penalties and claims administration costs are not covered by 
the trust fund. BP’s obligation to make contributions to the trust fund was 
recognized in full in the 2010 group income statement and the remaining 
liability to fund the Trust is included within other payables on the balance 
sheet after taking account of the time value of money. The establishment 
of the trust fund does not represent a cap or floor on BP’s liabilities and BP 
does not admit to a liability of this amount.

An asset has been recognized representing BP’s right to receive 
reimbursement from the trust fund. This is the portion of the estimated 
future expenditure provided for that will be settled by payments from 
the trust fund. We use the term “reimbursement asset” to describe this 
asset. BP will not actually receive any reimbursements from the trust fund, 
instead payments will be made directly to claimants from the trust fund, 
and BP will be released from its corresponding obligation.

156    BP Annual Report and Form 20-F 2011

Additional information for shareholdersContingent liabilities relating to the Gulf of Mexico oil spill
BP has provided for its best estimate of certain claims under the Oil 
Pollution Act 1990 (OPA 90) that will be paid through the $20-billion 
trust fund, including the increased estimate of the cost of individual and 
business claims as a result of the proposed settlement announced on 
3 March 2012 as described in Note 2 and Note 36. It is not possible, at 
this time, to measure reliably any other items that will be paid from the 
trust fund, namely any obligation in relation to Natural Resource Damages 
claims (except for the estimated costs of the assessment phase and the 
costs relating to emergency and early restoration agreements) and claims 
asserted in civil litigation, including any further litigation through potential 
opt-outs from the proposed settlement agreement with the Plaintiffs’ 
Steering Committee announced on 3 March 2012 (see page 76 for further 
information), nor is it practicable to estimate their magnitude or possible 
timing of payment. Although these items, which will be paid through the 
trust fund, have not been provided for at this time, BP’s full obligation 
under the $20-billion trust fund was expensed in the income statement in 
2010, taking account of the time value of money.

For those items not covered by the trust fund it is not possible to 

measure reliably any obligation in relation to other litigation or potential 
fines and penalties except, subject to certain assumptions, for those 
relating to the Clean Water Act. Therefore no amounts have been provided 
for these items as at 31 December 2011. There are a number of federal 
and state environmental and other provisions of law, other than the Clean 
Water Act, under which one or more governmental agencies could seek 
civil fines and penalties from BP. Given the large number of claims that 
may be asserted, it is not possible at this time to determine whether and 
to what extent any such claims would be successful or what penalties or 
fines would be assessed.

Pensions and other post-retirement benefits
Accounting for pensions and other post-retirement benefits involves 
judgement about uncertain events, including estimated retirement 
dates, salary levels at retirement, mortality rates, rates of return on plan 
assets, determination of discount rates for measuring plan obligations, 
assumptions for inflation rates, US healthcare cost trend rates and rates of 
utilization of healthcare services by US retirees.

These assumptions are based on the environment in each country. 
Determination of the projected benefit obligations for the group’s defined 
benefit pension and post-retirement plans is important to the recorded 
amounts for such obligations on the balance sheet and to the amount of 
benefit expense in the income statement. The assumptions used may 
vary from year to year, which will affect future results of operations. Any 
differences between these assumptions and the actual outcome also 
affect future results of operations.

Pension and other post-retirement benefit assumptions are 

reviewed by management at the end of each year. These assumptions 
are used to determine the projected benefit obligation at the year-end and 
hence the surpluses and deficits recorded on the group’s balance sheet, 
and pension and other post-retirement benefit expense for the following 
year.

The pension and other post-retirement benefit assumptions at 

December 2011, 2010 and 2009 are provided in Financial statements – 
Note 37 on page 234.

The assumed rate of investment return, discount rate, inflation 

rate and the US healthcare cost trend rate have a significant effect on the 
amounts reported. A sensitivity analysis of the impact of changes in these 
assumptions on the benefit expense and obligation is provided in Financial 
statements – Note 37 on page 234.

In addition to the financial assumptions, we regularly review the 
demographic and mortality assumptions. Mortality assumptions reflect 
best practice in the countries in which we provide pensions and have been 
chosen with regard to the latest available published tables adjusted where 
appropriate to reflect the experience of the group and an extrapolation of 
past longevity improvements into the future. A sensitivity analysis of the 
impact of changes in the mortality assumptions on the benefit expense 
and obligation is provided in Financial statements – Note 37 on page 234.
Actuarial gains and losses are recognized in full within other 

comprehensive income in the year in which they occur.

Property, plant and equipment

BP has freehold and leasehold interests in real estate in numerous 
countries, but no individual property is significant to the group as a whole. 
See Exploration and Production on page 80 for a description of the group’s 
significant reserves and sources of crude oil and natural gas. Significant 
plans to construct, expand or improve specific facilities are described under 
each of the business headings within this section.

BP offers most of its employees the opportunity to acquire a shareholding 
in the company through savings-related and/or matching share plan 
arrangements. BP also uses performance plans and option plans (see 
Financial statements – Note 40 on page 246) as elements of remuneration 
for executive directors and senior employees.

Shares acquired through the company’s employee share plans 

rank pari passu with shares in issue and have no special rights, save 
as described below. For legal and practical reasons, the rules of these 
plans set out the consequences of a change of control of the company, 
and generally provide for options and conditional awards to vest on an 
accelerated basis.

Matching and saving plans
BP ShareMatch plans
These matching share plans give employees the opportunity to buy 
ordinary shares in BP p.l.c. and receive free matching shares in BP p.l.c., 
up to a predetermined limit. The plans are run in the UK and in more than 
50 other countries. The UK plan is an approved HMRC plan and runs on 
a monthly basis. Under the UK plan, shares must be held in trust for at 
least three years to receive beneficial tax treatment. In other countries, 
the plan is run on an annual basis with shares being held in trust for three 
years. The plan is operated on a cash basis in those countries where there 
are regulatory restrictions preventing the holding of BP shares. When the 
employee leaves BP all shares must be removed from trust and units 
under the plan operated on a cash basis must be encashed.

Once shares have been awarded to an employee under the plan, 

the employee may instruct the trustee how to vote their shares.

BP ShareSave Plan
This is an approved HMRC plan which is open to all eligible UK employees. 
Participants can contribute up to a maximum of £250 per month from 
their net salary to a savings account over a three- or five-year contractual 
savings period. At the end of the savings period, they are entitled to 
purchase shares in BP p.l.c. at a preset price determined on the date when 
the invitations are sent to eligible employees. This price is usually set at a 
discount to the market price of a share of up to 20%. The option must be 
exercised within six months of maturity of the savings contract, otherwise 
it lapses. The plan is run in the UK and options are granted annually, usually 
in June. Participants leaving for a qualifying reason before the savings 
contract matured will have up to six months in which to use their savings 
to exercise their options on a pro-rated basis.

Local plans
In some countries, BP provides local scheme benefits, the rules and 
qualifications for which vary according to local circumstances. Certain US 
employees may participate in a defined contribution (401k) plan in which 
BP matches employee contributions up to certain limits. Participants may 
invest in several investment options including a BP Stock Fund that holds 
BP ADSs and a small percentage of cash. At 31 December 2011 the BP 
Stock Fund held 39,026,928 BP ADSs with a market value of $1,682 million 
(2010: 38,382,657 BP ADSs and $1,715 million). Participants in the fund as 
of the record date may direct the trustee how to vote their portion of the 
BP Stock Fund.

Cash-settled share-based payments
Grants are settled in cash where participants are located in a country 
whose regulatory environment prohibits the holding of BP shares.

Employee Share Ownership Plan Trusts (ESOPs)
ESOPs have been established to hold BP shares to satisfy any releases 
made to participants under the Executive Directors’ Incentive Plan, the 
Long-Term Performance Plan and the Share Option Plan. The ESOPs 
have waived their rights to dividends on shares held for future awards and 
are funded by the group. Pending vesting, the ESOPs have independent 
trustees that have the discretion in relation to the voting of such shares. 
Until such time as the company’s own shares held by the ESOPs vest 
unconditionally in employees, the amount paid for those shares is 
deducted in arriving at shareholders’ equity (see Financial statements – 
Note 39 on page 242). Assets and liabilities of the ESOPs are recognized 
as assets and liabilities of the group.

At 31 December 2011, the ESOPs held 27,784,503 shares 

(2010 11,477,253 shares and 2009 18,062,246 shares) for potential  
future awards, which had a market value of $197 million (2010 $82 million 
and 2009 $174 million).

2011 are set out in Financial statements – Note 38 on page 241.

At the AGM on 14 April 2011, authorization was given to the 
directors to allot shares up to an aggregate nominal amount equal to 
$3,133 million. Authority was also given to the directors to allot shares for 
cash and to dispose of treasury shares, other than by way of rights issue, 
up to a maximum of $235 million, without having to offer such shares 
to existing shareholders. These authorities are given for the period until 
the next AGM in 2012 or 14 July 2012, whichever is the earlier. These 
authorities are renewed annually at the AGM.

Dividends

When dividends are paid on its ordinary shares, BP’s policy is to pay 
interim dividends on a quarterly basis.

BP policy is also to announce dividends for ordinary shares in US 

dollars and state an equivalent sterling dividend. Dividends on BP ordinary 
shares will be paid in sterling and on BP ADSs in US dollars. The rate of 
exchange used to determine the sterling amount equivalent is the average 
of the market exchange rates in London over the four business days prior 
to the sterling equivalent announcement date. The directors may choose 
to declare dividends in any currency provided that a sterling equivalent 
is announced, but it is not the company’s intention to change its current 
policy of announcing dividends on ordinary shares in US dollars.

Information regarding dividends announced and paid by the 
company on ordinary shares and preference shares is provided in Financial 
statements – Note 19 on page 212.

A Scrip Dividend Programme (Programme) was introduced in 
2011 which enables BP ordinary shareholders and ADS holders to elect to 
receive new fully paid ordinary shares in BP (or ADSs in the case of ADS 
holders) instead of cash. The operation of the Programme is always subject 
to the directors’ decision to make the scrip offer available in respect of 
any particular dividend. Should the directors decide not to offer the scrip in 
respect of any particular dividend, cash will automatically be paid instead.

Future dividends will be dependent on future earnings, the financial 

condition of the group, the Risk factors set out on pages 59-63 and other 
matters that may affect the business of the group set out in Our strategy 
on pages 37-41 and in Liquidity and capital resources on page 103.

company per ADS for each of the past five years.

Proceedings relating to the Deepwater Horizon oil spill
BP p.l.c., BP Exploration & Production Inc. (BP E&P) and various other BP 
entities (collectively referred to as BP) are among the companies named 
as defendants in approximately 600 private civil lawsuits resulting from the 
20 April 2010 explosions and fire on the semi-submersible rig Deepwater 
Horizon and resulting oil spill (the Incident) and further actions are likely 
to be brought. BP E&P is lease operator of Mississippi Canyon, Block 
252 in the Gulf of Mexico (Macondo), where the Deepwater Horizon was 
deployed at the time of the Incident. The other working interest owners at 
the time of the Incident were Anadarko Petroleum Company (Anadarko) 
and MOEX Offshore 2007 LLC (MOEX). The Deepwater Horizon, 
which was owned and operated by certain affiliates of Transocean Ltd. 
(Transocean), sank on 22 April 2010. The pending lawsuits and/or claims 
arising from the Incident have been brought in US federal and state courts. 
Plaintiffs include individuals, corporations, insurers, and governmental 
entities and many of the lawsuits purport to be class actions. The lawsuits 
assert, among others, claims for personal injury in connection with the 
Incident itself and the response to it, wrongful death, commercial and 
economic injury, breach of contract and violations of statutes. The lawsuits 
seek various remedies including compensation to injured workers and 
families of deceased workers, recovery for commercial losses and property 
damage, claims for environmental damage, remediation costs, claims 
for unpaid wages, injunctive and declaratory relief, treble damages and 
punitive damages. Purported classes of claimants include residents of 
the states of Louisiana, Mississippi, Alabama, Florida, Texas, Tennessee, 
Kentucky, Georgia and South Carolina, property owners and rental agents, 
fishermen and persons dependent on the fishing industry, charter boat 
owners and deck hands, marina owners, gasoline distributors, shipping 
interests, restaurant and hotel owners, cruise lines and others who are 
property and/or business owners alleged to have suffered economic loss. 
Among other claims arising from the spill response efforts, lawsuits have 
been filed claiming that additional payments are due by BP under certain 
Master Vessel Charter Agreements entered into in the course of the 
Vessels of Opportunity Program implemented as part of the response to 
the Incident.

Shareholder derivative lawsuits related to the Incident have also 

been filed in US federal and state courts against various current and 
former officers and directors of BP alleging, among other things, breach 
of fiduciary duty, gross mismanagement, abuse of control and waste of 
corporate assets. On 15 September 2011, the judge in the federal multi-
district litigation proceeding in Houston granted BP’s motion to dismiss the 
consolidated shareholder derivative litigation pending there on the grounds 
that the courts of England are the appropriate forum for the litigation. On 
8 December 2011, a final judgment was entered dismissing the shareholder 
derivative case, and on 3 January 2012, one of the derivative plaintiffs filed 
a notice of appeal to the US Court of Appeals for the Fifth Circuit.

On 13 February 2012, the judge in the federal multi-district litigation 
proceeding in Houston issued two decisions on the defendants’ motions to 
dismiss the two consolidated securities fraud complaints filed on behalf of 
purported classes of BP ordinary shareholders and ADS holders. In those 
decisions the court dismissed all of the claims of the ordinary shareholders, 
dismissed the claims of the lead class of ADS holders against most of the 
individual defendants while holding that a subset of the claims against two 
individual defendants and the corporate defendants could proceed, and 
dismissed all of the claims of a smaller purported subclass with leave to 
re-plead in 20 days.

Purported class action lawsuits have been filed in US federal courts 

against BP entities and various current and former officers and directors 
alleging, among other things, securities fraud claims, violations of the 
Employee Retirement Income Security Act (ERISA) and contractual and 
quasi-contractual claims related to the cancellation of the dividend on 
16 June 2010. In addition, BP has been named in several lawsuits alleging 
claims under the Racketeer-Influenced and Corrupt Organizations Act 
(RICO). In August 2010, many of the lawsuits pending in federal court were 
consolidated by the Federal Judicial Panel on Multidistrict Litigation into 

160    BP Annual Report and Form 20-F 2011

two multi-district litigation proceedings, one in federal court in Houston for 
the securities, derivative, ERISA and dividend cases and another in federal 
court in New Orleans for the remaining cases.

On 1 June 2010, the US Department of Justice (DoJ) announced 

that it is conducting an investigation into the Incident encompassing 
possible violations of US civil or criminal laws. The types of enforcement 
action that might be pursued and the nature of the remedies that might 
be sought will depend on the judgement and discretion of the prosecutors 
and regulatory authorities and their assessment as to whether BP has 
violated any applicable laws and its culpability following their investigations. 
Such enforcement actions could include criminal proceedings against 
BP and/or employees of the group. Prosecutors have broad discretion in 
identifying what, if any, charges to pursue, but such charges could include, 
among others, criminal environmental, criminal securities, manslaughter 
and obstruction-related offences. The United States filed a civil complaint 
in the multi-district litigation proceeding in New Orleans against BP E&P 
and others on 15 December 2010 (DoJ Action). The complaint seeks a 
declaration of liability under the Oil Pollution Act of 1990 (OPA 90) and civil 
penalties under the Clean Water Act and sets forth a purported reservation 
of rights on behalf of the US to amend the complaint or file additional 
complaints seeking various remedies under various US federal laws 
and statutes. On 8 December 2011, the US brought a motion for partial 
summary judgment seeking, among other things, an order finding that BP, 
Transocean, and Anadarko are strictly liable for a civil penalty under Section 
311(b) (7)(A) of the Clean Water Act. This motion remains pending.

On 18 February 2011, Transocean filed a third-party complaint 

against BP, the US government, and other corporations involved in the 
Incident, naming those entities as formal parties in its Limitation of Liability 
action pending in federal court in New Orleans.

On 4 April 2011, BP initiated contractual out-of-court dispute 

resolution proceedings against Anadarko and MOEX, claiming that 
they have breached the parties’ contract by failing to reimburse BP 
for their working-interest share of Incident-related costs. On 19 April 
2011, Anadarko filed a cross-claim against BP, alleging gross negligence 
and 15 other counts under state and federal laws. Anadarko sought a 
declaration that it was excused from its contractual obligation to pay 
Incident-related costs. Anadarko also sought damages from alleged 
economic losses and contribution or indemnity for claims filed against it 
by other parties. On 20 May 2011, BP and MOEX announced a settlement 
agreement of all claims between them, including a cross-claim brought 
by MOEX on 19 April 2011 similar to the Anadarko claim. Under the 
settlement agreement, MOEX has paid BP $1.065 billion, which BP has 
applied towards the $20-billion Trust and has also agreed to transfer all of 
its 10% interest in the MC252 lease to BP. On 17 October 2011, BP and 
Anadarko announced that they had reached a final agreement to settle all 
claims between the companies related to the Incident, including mutual 
releases of all claims between BP and Anadarko that are subject to the 
contractual out-of-court dispute resolution proceedings or the federal 
multi-district litigation proceeding in New Orleans. Under the settlement 
agreement, Anadarko has paid BP $4 billion, which BP has applied towards 
the $20-billion Trust, and has also agreed to transfer all of its 25% interest 
in the MC252 lease to BP. The settlement agreement also grants Anadarko 
the opportunity for a 12.5% participation in certain future recoveries 
from third parties and certain insurance proceeds in the event that such 
recoveries and proceeds exceed $1.5 billion in aggregate. Any such 
payments to Anadarko are capped at a total of $1 billion. BP has agreed to 
indemnify Anadarko and MOEX for certain claims arising from the Incident 
(excluding civil, criminal or administrative fines and penalties, claims for 
punitive damages, and certain other claims). The settlement agreements 
with Anadarko and MOEX are not an admission of liability by any party 
regarding the Incident.

On 20 April 2011, Transocean filed claims in its Limitation of 
Liability action alleging that BP had breached BP America Production 
Company’s contract with Transocean Holdings LLC by BP not agreeing 
to indemnify Transocean against liability related to the Incident and by not 
paying certain invoices. Transocean also asserted claims against BP under 
state law, maritime law, and OPA 90 for contribution. On 1 November 
2011, Transocean filed a motion for partial summary judgment on certain 
claims filed in the Limitation Action and the DoJ Action between BP and 
Transocean. Transocean’s motion sought an order which would bar BP’s 

Additional information for shareholderscontribution claims against Transocean and require BP to defend and 
indemnify Transocean against all pollution claims, including those resulting 
from any gross negligence, and from civil fines and penalties sought by the 
government. On 7 December 2011, BP filed a cross-motion for  
summary judgment seeking an order that BP is not required to indemnify 
Transocean for any civil fines and penalties sought by the government or 
for punitive damages.

On 26 January 2012, the judge ruled on BP’s and Transocean’s 
indemnity motions, holding that BP is required to indemnify Transocean 
for third-party claims for compensatory damages resulting from pollution 
originating beneath the surface of the water, regardless of whether 
the claim results from Transocean’s strict liability, negligence, or gross 
negligence. The court, however, ruled that BP does not owe Transocean 
indemnity for such claims to the extent Transocean is held liable for 
punitive damages or for civil penalties under the Clean Water Act, or 
if Transocean acted with intentional or wilful misconduct in excess of 
gross negligence. The court further held that BP’s obligation to defend 
Transocean for third-party claims does not require BP to fund Transocean’s 
defence of third-party claims at this time, nor does it include Transocean’s 
expenses in proving its right to indemnity. The court deferred a final ruling 
on the question of whether Transocean breached its drilling contract with 
BP so as to invalidate the contract’s indemnity clause.

On 22 February 2012, the judge ruled on motions filed in the 

DoJ Action by the US, Anadarko, and Transocean seeking early rulings 
regarding the liability of BP, Anadarko, and Transocean under OPA 90 and 
the Clean Water Act, but limited the order to addressing the discharge of 
hydrocarbons occurring under the surface of the water. Regarding OPA 
90, the judge held that BP and Anadarko are responsible parties under 
OPA 90 with regard to the subsurface discharge. The judge ruled that BP 
and Anadarko have joint and several liability under OPA 90 for removal 
costs and damages for such discharge, but did not rule on whether such 
liability under OPA 90 is unlimited. While the judge held that Transocean 
is not a responsible party under OPA 90 for subsurface discharge, the 
judge left open the question of whether Transocean may be liable under 
OPA 90 for removal costs for such discharge as the owner/operator of the 
Deepwater Horizon. Regarding the Clean Water Act, the judge held that 
the subsurface discharge was from the Macondo well, rather than from the 
Deepwater Horizon, and that BP and Anadarko are liable for civil penalties 
under Section 311 of the Clean Water Act as owners of the well. The judge 
left open the question of whether Transocean may be liable under the 
Clean Water Act as an operator of the Macondo well. 

On 20 April 2011, Halliburton Energy Services, Inc. (Halliburton), 

filed claims in Transocean’s Limitation of Liability action seeking 
indemnification from BP for claims brought against Halliburton in that 
action, and Cameron International Corporation (Cameron) asserted claims 
against BP for contribution under state law, maritime law, and OPA 90, as 
well as for contribution on the basis of comparative fault. Halliburton also 
asserted a claim for negligence, gross negligence and wilful misconduct 
against BP and others. On 19 April 2011, Halliburton filed a separate 
lawsuit in Texas state court seeking indemnification from BP E&P for 
certain tort and pollution-related liabilities resulting from the Incident. On 
3 May 2011, BP E&P removed Halliburton’s case to federal court, and 
on 9 August 2011, the action was transferred to the federal multi-district 
litigation proceedings pending in New Orleans.

Subsequently, on 30 November 2011, Halliburton filed a motion 
for summary judgment in the federal multi-district litigation proceedings 
pending in New Orleans. Halliburton’s motion seeks an order stating that 
Halliburton is entitled to full and complete indemnity, including payment of 
defence costs, from BP for claims related to the Incident and denying BP’s 
claims seeking contribution against Halliburton. On 21 December 2011, BP 
filed a cross-motion for partial summary judgment seeking an order that BP 
has no contractual obligation to indemnify Halliburton for fines, penalties, or 
punitive damages resulting from the Incident.

On 31 January 2012, the judge ruled on BP’s and Halliburton’s 

indemnity motions, holding that BP is required to indemnify Halliburton for 
third-party claims for compensatory damages resulting from pollution that 
did not originate from property or equipment of Halliburton located above 
the surface of the land or water, regardless of whether the claims result 
from Halliburton’s gross negligence. The court, however, ruled that BP 
does not owe Halliburton indemnity to the extent that Halliburton is held 

liable for punitive damages or for civil penalties under the Clean Water 
Act. The court further held that BP’s obligation to defend Halliburton for 
third-party claims does not require BP to fund Halliburton’s defence of 
third-party claims at this time, nor does it include Halliburton’s expenses in 
proving its right to indemnity. The court deferred ruling on whether BP is 
required to indemnify Halliburton for any penalties or fines under the Outer 
Continental Shelf Lands Act. It also deferred ruling on whether Halliburton 
acted so as to invalidate the indemnity by breaching its contract with BP, 
by committing fraud, or by committing another act that materially increased 
the risk to BP or prejudiced the rights of BP as an indemnitor.

On 1 September 2011, Halliburton filed an additional lawsuit  
against BP in Texas state court. Its complaint alleges that BP did not 
identify the existence of a purported hydrocarbon zone at the Macondo 
well to Halliburton in connection with Halliburton’s cement work performed 
before the Incident and that BP has concealed the existence of this 
purported hydrocarbon zone following the Incident. Halliburton claims that 
the alleged failure to identify this information has harmed its business 
ventures and reputation and resulted in lost profits and other damages. On 
16 September 2011, BP removed the action to federal court, where it was 
stayed pending a decision by the Judicial Panel on Multidistrict Litigation 
on transfer of the action to the multi-district litigation proceeding in New 
Orleans. On 1 September 2011, Halliburton also moved to amend its 
claims in Transocean’s Limitation of Liability action to add claims for fraud 
based on similar factual allegations to those included in its 1 September 
2011 lawsuit against BP in Texas state court. On 11 October 2011, the 
magistrate judge in the federal multi-district litigation proceeding in New 
Orleans denied Halliburton’s motion to amend its claims, and Halliburton’s 
motion to review the order was denied by the judge on 19 December 
2011.

On 20 April 2011, BP asserted claims against Cameron, Halliburton, 

and Transocean in the Limitation of Liability action. BP’s claims against 
Transocean include breach of contract, unseaworthiness of the Deepwater 
Horizon vessel, negligence (or gross negligence and/or gross fault as 
may be established at trial based upon the evidence), contribution and 
subrogation for costs (including those arising from litigation claims) 
resulting from the Incident, as well as a declaratory claim that Transocean 
is wholly or partly at fault for the Incident and responsible for its 
proportionate share of the costs and damages. BP asserted claims against 
Halliburton for fraud and fraudulent concealment based on Halliburton’s 
misrepresentations to BP concerning, among other things, the stability 
testing on the foamed cement used at the Macondo well; for negligence 
(or, if established by the evidence at trial, gross negligence) based on 
Halliburton’s performance of its professional services, including cementing 
and mud logging services; and for contribution and subrogation for 
amounts that BP has paid in responding to the Incident, as well as in OPA 
assessments and in payments to plaintiffs. BP filed a similar complaint in 
federal court in the Southern District of Texas, Houston Division, against 
Halliburton, and the action was transferred on 4 May 2011 to the federal 
multi-district litigation proceeding pending in New Orleans.

On 20 April 2011, BP filed claims against Cameron, Halliburton, and 

Transocean in the DoJ Action, seeking contribution for any assessments 
against BP under OPA 90 based on those entities’ fault. On 20 June 2011, 
Cameron and Halliburton moved to dismiss BP’s claims against them in 
the DoJ Action. BP’s claim against Cameron has been resolved pursuant to 
settlement, but Halliburton’s motion remains pending.

On 16 December 2011, BP and Cameron announced their 

agreement to settle all claims between the companies related to the 
Incident, including mutual releases of claims between BP and Cameron 
that are subject to the federal multi-district litigation proceeding in New 
Orleans. Under the settlement agreement, Cameron has paid BP $250 
million in cash in January 2012, which BP has applied towards the 
$20-billion Trust. BP has agreed to indemnify Cameron for compensatory 
claims arising from the Incident, including claims brought relating to 
pollution damage or any damage to natural resources, but excluding civil, 
criminal or administrative fines and penalties, claims for punitive damages, 
and certain other claims.

On 20 May 2011, Dril-Quip, Inc. and M-I L.L.C. (M-I) filed claims 

against BP in Transocean’s Limitation of Liability action, each claiming 
a right to contribution from BP for damages assessed against them as 
a result of the Incident, based on allegations of negligence. M-I also 

BP Annual Report and Form 20-F 2011    161

Additional information for shareholdersAdditional information for shareholdersclaimed a right to indemnity for such damages based on its well services 
contracts with BP. On 20 June 2011, BP filed counter-complaints against 
Dril-Quip, Inc. and M-I, asking for contribution and subrogation based on 
those entities’ fault in connection with the Incident and under OPA 90, 
and seeking declaratory judgment that Dril-Quip, Inc. and M-I caused or 
contributed to, and are responsible in whole or in part for damages incurred 
by BP in relation to, the Incident. On 20 January 2012, the court granted 
Dril-Quip, Inc.’s motion for summary judgment, dismissing with prejudice 
all claims asserted against Dril-Quip in the federal multi-district litigation 
proceeding in New Orleans.

On 21 January 2012, BP and M-I entered into an agreement settling 
all claims between the companies related to the Incident, including mutual 
releases of claims between BP and M-I that are subject to the federal 
multi-district litigation proceeding in New Orleans. Under the settlement 
agreement, M-I has agreed to indemnify BP for personal injury and death 
claims brought by M-I employees. BP has agreed to indemnify M-I for 
claims resulting from the Incident, but excluding certain claims.

On 30 May 2011, Transocean filed claims against BP in the DoJ 
Action alleging that BP America Production Company had breached its 
contract with Transocean Holdings LLC by not agreeing to indemnify 
Transocean against liability related to the Incident. Transocean also 
asserted claims against BP under state law, maritime law, and OPA 90 for 
contribution. On 20 June 2011, Cameron filed similar claims against BP in 
the DoJ Action.

On 26 August 2011, the judge in the federal multi-district litigation 

proceeding in New Orleans granted in part BP’s motion to dismiss a 
master complaint raising claims for economic loss by private plaintiffs, 
dismissing plaintiffs’ state law claims and limiting the types of maritime law 
claims plaintiffs may pursue, but also held that certain classes of claimants 
may seek punitive damages under general maritime law. The judge did not, 
however, lift an earlier stay on the underlying individual complaints raising 
those claims or otherwise apply his dismissal of the master complaint to 
those individual complaints.

On 14 September 2011, the BOEMRE issued its report (BOEMRE 
Report) regarding the causes of the 20 April 2010 Macondo well blowout. 
The BOEMRE Report states that decisions by BP, Halliburton and 
Transocean increased the risk or failed to fully consider or mitigate the 
risk of a blowout on 20 April 2010. The BOEMRE Report also states that 
BP, and Transocean and Halliburton, violated certain regulations related 
to offshore drilling. In itself, the BOEMRE Report does not constitute 
the initiation of enforcement proceedings relating to any violation. On 
12 October 2011, the U.S. Department of the Interior Bureau of Safety 
and Environmental Enforcement issued to BP E&P, Transocean, and 
Halliburton Notification of Incidents of Noncompliance (INCs). The 
notification issued to BP E&P is for a number of alleged regulatory 
violations concerning Macondo well operations. The Department of 
Interior has indicated that this list of violations may be supplemented as 
additional evidence is reviewed, and on 7 December 2011, the Bureau of 
Safety and Environmental Enforcement issued to BP E&P a second INC. 
This notification was issued to BP for five alleged violations related to 
drilling and abandonment operations at the Macondo well. BP has filed an 
administrative appeal with respect to the first and second INCs. BP has 
also filed a joint stay of proceedings with the Department of Interior with 
respect to the 12 October 2011 INCs and plans to file a joint stay regarding 
the 7 December 2011 INCs.

On 30 September 2011, the judge in the federal multi-district 
litigation proceeding in New Orleans granted in part BP’s motion to dismiss 
a master complaint asserting personal injury claims on behalf of persons 
exposed to crude oil or chemical dispersants, dismissing plaintiffs’ state 
law claims, claims by seamen for punitive damages, claims for medical 
monitoring damages by asymptomatic plaintiffs, claims for battery and 
nuisance under maritime law, and claims alleging negligence per se. As 
with his other rulings on motions to dismiss master complaints, the judge 
did not lift an earlier stay on the underlying individual complaints raising 
those claims or otherwise apply his dismissal of the master complaint to 
those individual complaints.

A Trial of Liability, Limitation, Exoneration, and Fault Allocation 
was originally scheduled to begin in the federal multi-district litigation 
proceeding in New Orleans in February 2012. The court’s pre-trial order 
issued 14 September 2011 provided for the trial to proceed in three phases 

162    BP Annual Report and Form 20-F 2011

and to include issues asserted in or relevant to the claims, counterclaims, 
cross-claims, third-party claims, and comparative fault defences raised in 
Transocean’s Limitation of Liability Action.

On 18 October 2011, Cameron filed a petition for writ of mandamus 
with US Court of Appeals for the Fifth Circuit seeking an order vacating the 
trial plan for the 27 February 2012 trial and requiring that all claims against 
Cameron in that proceeding be tried before a jury. On 26 December 2011, 
the Court of Appeals denied the application for mandamus.

The State of Alabama has filed a lawsuit seeking damages for 

alleged economic and environmental harms, including natural resource 
damages, civil penalties under state law, declaratory and injunctive 
relief, and punitive damages as a result of the Incident. The State of 
Louisiana has filed a lawsuit to declare various BP entities (as well as 
other entities) liable for removal costs and damages, including natural 
resource damages under federal and state law, to recover civil penalties, 
attorney’s fees, and response costs under state law, and to recover 
for alleged negligence, nuisance, trespass, fraudulent concealment 
and negligent misrepresentation of material facts regarding safety 
procedures and BP’s (and other defendants’) ability to manage the 
oil spill, unjust enrichment from economic and other damages to the 
State of Louisiana and its citizens, and punitive damages. The Louisiana 
Department of Environmental Quality has issued an administrative order 
seeking environmental civil penalties and other relief under state law. 
On 23 September 2011, BP removed this matter to federal district court. 
Several local governments in the State of Louisiana have filed suits 
under state wildlife statutes seeking penalties for damage to wildlife as a 
result of the spill. On 10 December 2010, the Mississippi Department of 
Environmental Quality issued a Complaint and Notice of Violation alleging 
violations of several state environmental statutes.

On 14 November 2011, the judge in the federal multi-district 
litigation proceeding in New Orleans granted in part BP’s motion to 
dismiss the complaints filed by the States of Alabama and Louisiana. 
The judge’s order dismissed the States’ claims brought under state law, 
including claims for civil penalties and the State of Louisiana’s request 
for a declaratory judgment under the Louisiana Oil Spill Prevention and 
Response Act, holding that those claims were pre-empted by federal 
law. It also dismissed the State of Louisiana’s claims of nuisance and 
trespass under general maritime law. The judge’s order further held that 
the States have stated claims for negligence and products liability under 
general maritime law, that the States have sufficiently alleged presentment 
of their claims under OPA 90, and that the States may seek punitive 
damages under general maritime law. On 9 December 2011, the judge 
in the federal multi-district litigation proceeding in New Orleans granted 
in part BP’s motion to dismiss a master complaint brought on behalf of 
local government entities. The judge’s order dismissed plaintiffs’ state law 
claims and limited the types of maritime law claims plaintiffs may pursue, 
but also held that the plaintiffs have sufficiently alleged presentment 
of their claims under OPA 90 and that certain local government entity 
claimants may seek punitive damages under general maritime law. The 
judge did not, however, lift an earlier stay on the underlying individual 
complaints raising those claims or otherwise apply his dismissal of the 
master complaint to those individual complaints.

On 9 December 2011 and 28 December 2011, the judge in the 

federal multi-district litigation proceeding in New Orleans also granted BP’s 
motions to dismiss complaints filed by the District Attorneys of 11 parishes 
in the State of Louisiana seeking penalties for damage to wildlife, holding 
that those claims are pre-empted by the Clean Water Act. Many of the 
parishes have filed notices of appeal to the U.S. Court of Appeals for the 
Fifth Circuit.

On 3 March 2012, BP announced a settlement with the Plaintiffs’ 

Steering Committee (PSC) in the federal Multi-District Litigation 
proceedings pending in New Orleans (MDL 2179) to resolve the substantial 
majority of legitimate private economic loss and medical claims stemming 
from the Incident. The agreement in principle is subject to final written 
agreement and court approvals. 

The proposed settlement is comprised of two separate 
agreements. The first of these resolves economic loss claims and the 
other resolves medical claims. The proposed agreement to resolve 
economic loss claims includes a $2.3 billion BP commitment to help 
resolve economic loss claims related to the Gulf seafood industry and a 

Additional information for shareholdersfund to support continued advertising that promotes Gulf Coast tourism. 
It also resolves claims for additional payments under certain Master 
Vessel Charter Agreements entered into in the course of the Vessels of 
Opportunity Program implemented as part of the response to the Incident.
The proposed agreement to resolve medical claims involves 

payments based on a matrix for certain currently manifested physical 
conditions, as well as a 21-year medical consultation programme for 
qualifying class members. It also provides that class members claiming 
later-manifested physical conditions may pursue their claims through a 
mediation/litigation process. Consistent with its commitment to the Gulf, 
BP has also agreed to provide $105 million to improve the availability, 
scope and quality of healthcare in Gulf communities. This healthcare 
outreach programme would be available to all individuals in those 
communities, regardless of whether they are class members. 

Each proposed agreement provides that class members would be 
compensated for their claims on a claims-made basis, according to agreed 
compensation protocols in separate court-supervised claims processes. 
The compensation protocols under the proposed economic loss settlement 
agreement include a risk transfer premium (RTP). The RTP is an agreed 
factor to be used in calculating certain types of damages, including 
potential future damages that are not currently known, relating to the 
Incident.

BP estimates the cost of the proposed settlement would be 
approximately $7.8 billion (including the $2.3 billion commitment to 
help resolve economic loss claims related to the Gulf seafood industry). 
While this is BP’s reliable best estimate of the cost of the proposed 
settlement, it is possible that the actual cost could be higher or lower 
than this estimate depending on the outcomes of the court-supervised 
claims processes. In accordance with its normal procedures, BP will 
re-evaluate the assumptions underlying this estimate on a quarterly basis 
as more information, including the outcomes of the court-supervised 
claims processes, becomes available. (For more information, see Financial 
statements – Note 36.) 

At this time, BP expects all settlements under these agreements 

to be paid from the Trust. Other costs to be paid from the Trust include 
state and local government claims, state and local response costs, 
natural resource damages and related claims, and final judgments and 
settlements. It is not possible at this time to determine whether the Trust 
will be sufficient to satisfy all of these claims as well as those under the 
proposed settlement. Should the Trust not be sufficient, payments under 
the proposed settlement would be made by BP directly.

The proposed economic loss settlement provides for a transition 

from the Gulf Coast Claims Facility (GCCF) to a new court-supervised 
claims programme, to administer payments made to qualifying class 
members. A court-supervised transitional claims process will be in 
operation while the infrastructure for the new settlement claims process 
is put in place. During this transitional period, the processing of claims 
that have been submitted to the GCCF will continue, and new claimants 
may submit their claims. BP has agreed not to wait for final approval of 
the economic loss settlement before claims are paid. The economic loss 
claims process will continue under court supervision before final approval 
of the settlement, first under the transitional claims process, and then 
through the settlement claims process established by the proposed 
economic loss settlement.

Under the proposed settlement, class members would release and 

dismiss their claims against BP. The proposed settlement also provides 
that, to the extent permitted by law, BP will assign to the PSC certain of 
its claims, rights and recoveries against Transocean and Halliburton for 
damages with protections such that Transocean and Halliburton cannot 
pass those damages through to BP.

The proposed settlement is subject to reaching definitive and fully-

documented agreements within 45 days of 2 March 2012, and if those 
agreements are not reached, either party has the right to terminate the 
proposed settlement. Once definitive agreements have been reached, BP 
and the PSC will seek the court’s preliminary approval of the settlement. 
Under US federal law, there is an established procedure for determining 
the fairness, reasonableness and adequacy of class action settlements. 
Pursuant to this procedure, and subject to the court granting preliminary 
approval of both agreements, there would be an extensive outreach 
programme to the public to explain settlement agreements and class 

members’ rights, including the right to “opt out” of the classes, and the 
processes for making claims. The court would then conduct fairness 
hearings at which class members and various other parties would have an 
opportunity to be heard and present evidence and decide whether or not to 
approve each proposed settlement agreement. Should the number of class 
members opting out exceed an agreed and court-approved threshold, BP 
will have the right to terminate the proposed settlement.

The proposed settlement does not include claims made against 

BP by the DoJ or other federal agencies (including under the Clean Water 
Act and for Natural Resource Damages under the Oil Pollution Act) or by 
the states and local governments. Also excluded are certain other claims 
against BP, such as securities and shareholder claims pending in MDL 
2185, and claims based solely on the deepwater drilling moratorium and/or 
the related permitting process.

The court has subsequently ordered that the first phase of the trial 

be adjourned. The court will schedule a status conference to discuss issues 
raised by the proposed settlement and to set a new trial date.

On 15 September 2010, three Mexican states bordering the Gulf of 

Mexico (Veracruz, Quintana Roo, and Tamaulipas) filed lawsuits in federal 
court in Texas against several BP entities. These lawsuits allege that the 
Incident harmed their tourism, fishing, and commercial shipping industries 
(resulting in, among other things, diminished tax revenue), damaged natural 
resources and the environment, and caused the states to incur expenses 
in preparing a response to the Incident. On 9 December 2011, the judge 
in the federal multi-district litigation proceeding in New Orleans granted 
in part BP’s motion to dismiss the three Mexican states’ complaints, 
dismissing their claims under OPA 90 and for nuisance and negligence  
per se, and preserving their claims for negligence and gross negligence 
only to the extent there has been a physical injury to a proprietary 
interest of the states. On 5 April 2011, the State of Yucatan submitted 
a claim to the GCCF alleging potential damage to its natural resources 
and environment, and seeking to recover the cost of assessing the 
alleged damage. BP anticipates further claims from the Mexican federal 
government.

Citizens groups have also filed either lawsuits or notices of intent 
to file lawsuits seeking civil penalties and injunctive relief under the Clean 
Water Act and other environmental statutes. On 16 June 2011, the judge 
in the federal multi-district litigation proceeding in New Orleans granted 
BP’s motion to dismiss a master complaint raising claims for injunctive 
relief under various federal environmental statutes brought by various 
citizens groups and others. The judge did not, however, lift an earlier stay 
on the underlying individual complaints raising those claims for injunctive 
relief or otherwise apply his dismissal of the master complaint to those 
individual complaints. In addition, a different set of environmental groups 
filed a motion to reconsider dismissal of their Endangered Species Act 
claims on 14 July 2011. That motion remains pending. On 31 January 
2012, the court, on motion by the Center for Biological Diversity, entered 
final judgment on the basis of the 16 June 2011 order with respect to two 
actions brought against BP by that plaintiff. On 2 February 2012, the Center 
for Biological Diversity filed a notice of appeal of both actions.

On 15 July 2011, the judge granted BP’s motion to dismiss a 
master complaint raising RICO claims against BP. The court’s order 
dismissed the claims of the plaintiffs in four RICO cases encompassed by 
the master complaint.

The DoJ announced on 7 March 2011 that it created a unified task 
force of federal agencies, led by the DoJ Criminal Division, to investigate 
the Incident. Other US federal agencies may commence investigations 
relating to the Incident. The SEC and DoJ are investigating securities 
matters arising in relation to the Incident.

On 21 April 2011, BP entered a framework agreement with natural 

resource trustees for the US and five Gulf coast states, providing for up 
to $1 billion to be spent on early restoration projects to address natural 
resource injuries resulting from the Incident. Funding for these projects will 
come from the $20-billion Trust fund.

BP’s potential liabilities resulting from threatened, pending and 

potential future claims, lawsuits and enforcement actions relating to 
the Incident, together with the potential cost of implementing remedies 
sought in the various proceedings, cannot be fully estimated at this time 
but they have had and are expected to have a material adverse impact 
on the group’s business, competitive position, cash flows, prospects, 

BP Annual Report and Form 20-F 2011    163

Additional information for shareholdersAdditional information for shareholdersliquidity, shareholder returns and/or implementation of its strategic agenda, 
particularly in the US. These potential liabilities may continue to have a 
material adverse effect on the group’s results and financial condition. See 
Financial statements – Note 2 on pages 190-194 for information regarding 
the financial impact of the Incident.

Investigations and reports relating to the Deepwater Horizon oil spill
BP is subject to a number of investigations related to the Incident by 
numerous agencies of the US government. The related published reports 
are available on the websites of the agencies and commissions referred to 
below.

On 11 January 2011, the National Commission on the BP 
Deepwater Horizon Oil Spill and Offshore Drilling (National Commission), 
established by President Obama, published its report on the causes of the 
Incident and its recommendations for policy and regulatory changes for 
offshore drilling. On 17 February 2011, the National Commission’s Chief 
Counsel published a separate report on his investigation that provides 
additional information regarding the causes of the Incident.

In a report dated 20 March 2011, with an Addendum dated 
30 April 2011, the Joint Investigation Team (JIT) for the Marine Board of 
Investigation established by the US Coast Guard and Bureau of Ocean 
Energy Management (BOEMRE) issued the Final Report of the Forensic 
Examination of the Deepwater Horizon Blowout Preventer (BOP) prepared 
by Det Norske Veritas (BOP Report). The BOP Report concludes that 
the position of the drill pipe against the blind shear rams prevented the 
BOP from functioning as intended. Subsequently, BP helped to sponsor 
additional BOP testing conducted by Det Norske Veritas under court 
auspices, which concluded on 21 June 2011. BP continues to review the 
BOP Report and is in the process of evaluating the data obtained from the 
additional testing.

On 22 April 2011, the US Coast Guard issued its report (Maritime 
Report) focused upon the maritime aspects of the Incident. The Maritime 
Report criticizes Transocean’s maintenance operations and safety culture, 
while also criticizing the Republic of the Marshall Islands – the flag state 
responsible for certifying Transocean’s Deepwater Horizon vessel.

The US Chemical Safety and Hazard Investigation Board (CSB) 

is also conducting an investigation of the Incident that is focused on the 
explosions and fire, and not the resulting oil spill or response efforts. The 
CSB is expected to issue a single investigation report in 2012 that will 
seek to identify the alleged root cause(s) of the Incident, and recommend 
improvements to BP and industry practices and to regulatory programmes 
to prevent recurrence and mitigate potential consequences.

Also, at the request of the Department of the Interior, the National 

Academy of Engineering/National Research Council established a 
Committee (Committee) to examine the performance of the technologies 
and practices involved in the probable causes of the Incident and to identify 
and recommend technologies, practices, standards and other measures to 
avoid similar future events. On 17 November 2010, the Committee publicly 
released its interim report setting forth the Committee’s preliminary 
findings and observations on various actions and decisions including well 
design, cementing operations, well monitoring, and well control actions. 
The interim report also considers management, oversight, and regulation of 
offshore operations. On 14 December 2011, the Committee published its 
final report, including findings and recommendations. A second, unrelated 
National Academies Committee will be looking at the methodologies 
available for assessing spill impacts on ecosystem services in the Gulf of 
Mexico, with a final report expected in late 2012 or early 2013, and a third 
National Academies Committee will be studying methods for assessing the 
effectiveness of safety and environmental management systems (SEMS) 
established by offshore oil and gas operators.

On 10 March 2011, the Flow Rate Technical Group (FRTG), 

Department of the Interior, issued its final report titled “Assessment 
of Flow Rate Estimates for the Deepwater Horizon/Macondo Well Oil 
Spill.” The report provides a summary of the strengths and limitations of 
the different methods used by the US government to estimate the flow 
rate and a range of estimates from 13,000 b/d to over 100,000 b/d. The 
report concludes that the most accurate estimate was 53,000 b/d just 
prior to shut in, with an uncertainty on that value of ±10% based on FRTG 
collective experience and judgement, and, based on modelling, the flow on 
day one of the Incident was 62,000 b/d.

164    BP Annual Report and Form 20-F 2011

On 18 March 2011, the US Coast Guard ISPR team released its final 
report capturing lessons learned from the Incident as well as making 
recommendations on how to improve future oil spill response and recovery 
efforts.

Additionally, since April 2010, BP representatives have testified 
multiple times before the US Congress regarding the Incident. BP has 
provided documents and written information in response to requests from 
Members, committees and subcommittees of the US Congress.

Other legal proceedings
The US Federal Energy Regulatory Commission (FERC) and the US 
Commodity Futures Trading Commission (CFTC) are currently investigating 
several BP entities regarding trading in the next-day natural gas market at 
Houston Ship Channel during September, October and November 2008. 
The FERC Office of Enforcement staff notified BP on 12 November 2010 
of their preliminary conclusions relating to alleged market manipulation in 
violation of 18 C.F.R. Sec. 1c.1. On 30 November 2010, CFTC Enforcement 
staff also provided BP with a notice of intent to recommend charges 
based on the same conduct alleging that BP engaged in attempted market 
manipulation in violation of Section 6(c), 6(d), and 9(a)(2) of the Commodity 
Exchange Act. On 23 December 2010, BP submitted responses to the 
FERC and CFTC November 2010 notices providing a detailed response 
that it did not engage in any inappropriate or unlawful activity. On 28 July 
2011, the FERC staff issued a Notice of Alleged Violations stating that it 
had preliminarily determined that several BP entities fraudulently traded 
physical natural gas in the Houston Ship Channel and Katy markets 
and trading points to increase the value of their financial swing spread 
positions. Other investigations into BP’s trading activities continue to be 
conducted from time to time.

On 23 March 2005, an explosion and fire occurred in the 
isomerization unit of BP Products North America’s (BP Products) Texas 
City refinery as the unit was coming out of planned maintenance. Fifteen 
workers died in the incident and many others were injured. BP Products 
has resolved all civil injury claims arising from the March 2005 incident.

In March 2007, the US Chemical Safety and Hazard Investigation 

Board (CSB) issued a report on the incident. The report contained 
recommendations to the Texas City refinery and to the board of directors 
of BP. In May 2007, BP responded to the CSB’s recommendations. BP and 
the CSB will continue to discuss BP’s responses with the objective of the 
CSB’s agreeing to close out its recommendations.

On 25 October 2007, the DoJ announced that it had entered 

into a criminal plea agreement with BP Products related to the March 
2005 explosion and fire. On 4 February 2008, BP Products pleaded 
guilty, pursuant to the plea agreement, to one felony violation of the risk 
management planning regulations promulgated under the US Clean Air 
Act (CAA) and on 12 March 2009, the court accepted the plea agreement. 
In connection with the plea agreement, BP Products paid a $50-million 
criminal fine and was sentenced to three years’ probation which is set 
to expire on 12 March 2012. Compliance with a 2005 US Occupational 
Safety and Health Administration (OSHA) settlement agreement (2005 
Agreement) and a 2006 agreed order entered into by BP Products with 
the Texas Commission on Environmental Quality (TCEQ) are conditions of 
probation.

The Texas Office of Attorney General, on behalf of the Texas 

Commission on Environmental Quality (TCEQ), has filed a petition against 
BP Products asserting certain air emissions and reporting violations at the 
Texas City refinery from 2005 to 2010. BP Products settled this lawsuit by 
an Agreed Final Judgment entered by the court on 20 December 2011.
The Texas Attorney General filed a separate petition against BP 
Products asserting emissions violations relating to a 6 April 2010 flaring 
event. This lawsuit was also settled by the Agreed Final Judgment 
mentioned in the preceding paragraph. This emissions event is also the 
subject of a number of civil suits by many area workers and residents 
alleging personal injury and property damages and seeking substantial 
damages. In addition, this emissions event is the subject of a federal 
governmental investigation.

In September 2009, BP Products filed a petition to clarify specific 

required actions and deadlines under the 2005 Agreement with OSHA. 
That agreement resolved citations issued in connection with the March 
2005 Texas City refinery explosion. OSHA denied BP Products’ petition.

Additional information for shareholdersIn October 2009 OSHA issued citations to the Texas City refinery seeking 
a total of $87.4 million in civil penalties for alleged violations of the 2005 
Agreement and alleged process safety management violations.

A settlement agreement between BP Products and OSHA in 
August 2010 (2010 Agreement) resolved the petition filed by BP Products 
in September 2009 and the alleged violations of the 2005 Agreement. 
BP Products has paid a penalty of $50.6 million in that matter and 
agreed to perform certain abatement actions. Compliance with the 2010 
Agreement (which is set to expire on 12 March 2012) is also a condition of 
probation due to the linkage between this 2010 Agreement and the 2005 
Agreement.

On 6 May 2010, certain persons qualifying under the US Crime 

Victims’ Rights Act as victims in relation to the Texas City plea agreement 
requested that the federal court revoke BP Products’ probation based 
on alleged violations of the Court’s conditions of probation. The alleged 
violations of probation relate to the alleged failure to comply with the 2005 
Agreement.

The OSHA process safety management citations issued in October 

2009 were not resolved by the August 2010 settlement agreement. 
The proposed penalties in that matter are $30.7 million. The matter is 
currently before the OSH Review Commission which has assigned an 
Administrative Law Judge for purposes of mediation. These citations do 
not allege violations of the 2005 Agreement.

A shareholder derivative action was filed against several current 

and former BP officers and directors based on alleged violations of the US 
Clean Air Act (CAA) and Occupational Safety and Health Administration 
(OSHA) regulations at the Texas City refinery subsequent to the March 
2005 explosion and fire. An investigation by a special committee of 
BP’s board into the shareholder allegations has been completed and the 
committee has recommended that the allegations do not warrant action 
by BP against the officers and directors. BP filed a motion to dismiss the 
shareholder derivative action and a plea to the jurisdiction. On 16 June 
2011, the court granted BP’s plea to the jurisdiction and dismissed the 
action in its entirety. The shareholder has appealed the dismissal and the 
appeal is pending.

In March and August 2006, oil leaked from oil transit pipelines 

operated by BP Exploration (Alaska) Inc. (BPXA) at the Prudhoe Bay unit 
on the North Slope of Alaska. Several legal proceedings resulted from 
these events. On 29 November 2007, BPXA entered into a criminal plea 
agreement with the DoJ relating to these leaks. BPXA’s guilty plea, to a 
misdemeanour violation of the US Water Pollution Control Act, included 
a term of three years’ probation. On 29 November 2009, a spill of 
approximately 360 barrels of crude oil and produced water was discovered 
beneath a line running from a well pad to the Lisburne Processing Center 
in Prudhoe Bay, Alaska. On 17 November 2010, the US Probation Officer 
filed a petition in federal district court to revoke BPXA’s probation based 
on allegations that the Lisburne event was a criminal violation of state 
and federal law and therefore BPXA was in violation of its probation 
obligations. BPXA contested the petition at an evidentiary hearing that 
was completed on 7 December 2011 in U.S. District Court in Anchorage, 
Alaska. On 27 December 2011, the Court issued a decision and order 
finding that BPXA did not violate the terms of its probation, dismissing the 
government’s petition and terminating BPXA’s probation. 

On 12 May 2008, a BP p.l.c. shareholder filed a consolidated 
complaint alleging violations of federal securities law on behalf of a putative 
class of BP p.l.c. shareholders against BP p.l.c., BPXA, BP America, and 
four officers of the companies, based on alleged misrepresentations 
concerning the integrity of the Prudhoe Bay pipeline before its shutdown 
on 6 August 2006. On 8 February 2010, the Ninth Circuit Court of Appeals 
accepted BP’s appeal from a decision of the lower court granting in part 
and denying in part BP’s motion to dismiss the lawsuit. On 29 June 
2011, the Ninth Circuit ruled in BP’s favour that the filing of a trust related 
agreement with the SEC containing contractual obligations on the part of 
BP was not a misrepresentation which violated federal securities laws. The 
BP p.l.c. shareholder has filed an amended complaint, in response to which 
BP filed a new motion to dismiss, which is pending. On 31 March 2009, 
the United States filed a complaint seeking civil penalties and damages 
relating to the events at Prudhoe Bay. The complaint also involved claims 
related to asbestos handling, allegations of non-compliance at multiple 
facilities for failure to comply with EPA’s spill prevention plan regulations, 

and for non-compliance with US Department of Transportation orders and 
regulations. The parties settled the dispute and on 13 July 2011 the Court 
entered a Consent Agreement in which BPXA agreed to pay a $25-million 
penalty and to perform certain injunctive measures over the next three 
years with respect to pipeline inspection and maintenance. On 31 March 
2009, the State of Alaska filed a complaint seeking civil penalties and 
damages relating to these events. The complaint alleges that the two 
releases and BPXA’s corrosion management practices violated various 
statutory, contractual and common law duties to the State, resulting 
in penalty liability, damages for lost royalties and taxes, and liability for 
punitive damages. In December 2011, the State of Alaska and BPXA 
entered into a Dispute Resolution Agreement concerning this matter that 
will result in arbitration of the amount of the State’s lost royalty income and 
payment by BPXA of the additional amount of $10 million on account of 
other claims in the complaint.

Approximately 200 lawsuits were filed in state and federal courts 
in Alaska seeking compensatory and punitive damages arising out of the 
Exxon Valdez oil spill in Prince William Sound in March 1989. Most of 
those suits named Exxon (now ExxonMobil), Alyeska Pipeline Service 
Company (Alyeska), which operates the oil terminal at Valdez, and the 
other oil companies that own Alyeska. Alyeska initially responded to 
the spill until the response was taken over by Exxon. BP owns a 46.9% 
interest (reduced during 2001 from 50% by a sale of 3.1% to Phillips) 
in Alyeska through a subsidiary of BP America Inc. and briefly indirectly 
owned a further 20% interest in Alyeska following BP’s combination with 
Atlantic Richfield. Alyeska and its owners have settled all the claims against 
them under these lawsuits. Exxon has indicated that it may file a claim for 
contribution against Alyeska for a portion of the costs and damages that it 
has incurred. If any claims are asserted by Exxon that affect Alyeska and its 
owners, BP will defend the claims vigorously.

Since 1987, Atlantic Richfield Company (Atlantic Richfield), a 
subsidiary of BP, has been named as a co-defendant in numerous lawsuits 
brought in the US alleging injury to persons and property caused by lead 
pigment in paint. The majority of the lawsuits have been abandoned or 
dismissed against Atlantic Richfield. Atlantic Richfield is named in these 
lawsuits as alleged successor to International Smelting and Refining 
and another company that manufactured lead pigment during the period 
1920-1946. Plaintiffs include individuals and governmental entities. 
Several of the lawsuits purport to be class actions. The lawsuits seek 
various remedies including compensation to lead-poisoned children, cost 
to find and remove lead paint from buildings, medical monitoring and 
screening programmes, public warning and education of lead hazards, 
reimbursement of government healthcare costs and special education for 
lead-poisoned citizens and punitive damages. No lawsuit against Atlantic 
Richfield has been settled nor has Atlantic Richfield been subject to a final 
adverse judgment in any proceeding. The amounts claimed and, if such 
suits were successful, the costs of implementing the remedies sought in 
the various cases could be substantial. While it is not possible to predict 
the outcome of these legal actions, Atlantic Richfield believes that it has 
valid defences. It intends to defend such actions vigorously and believes 
that the incurrence of liability is remote. Consequently, BP believes that 
the impact of these lawsuits on the group’s results, financial position or 
liquidity will not be material.

On 8 March 2010, OSHA issued citations to BP’s Toledo refinery 

alleging violations of the Process Safety Management Standard, with 
penalties of approximately $3 million. These citations resulted from an 
inspection conducted pursuant to OSHA’s Petroleum Refinery Process 
Safety Management National Emphasis Program. BP Products has 
contested the citations, and the matter is currently scheduled for trial 
before the OSH Review Commission in June 2012.

In April 2009, Kenneth Abbott, as relator, filed a US False Claims 
Act lawsuit against BP, alleging that BP violated federal regulations, and 
made false statements in connection with its compliance with those 
regulations, by failing to have necessary documentation for the Atlantis 
subsea and other systems. BP is the operator and 56% interest owner 
of the Atlantis unit in production in the Gulf of Mexico. That complaint 
was unsealed in May 2010 and served on BP in June 2010. Abbott seeks 
damages measured by the value, net of royalties, of all past and future 
production from the Atlantis platform, trebled, plus penalties. In September 
2010, Kenneth Abbott and Food & Water Watch filed an amended 

BP Annual Report and Form 20-F 2011    165

Additional information for shareholdersAdditional information for shareholdersOn 17 May 2011, BP announced that both the Rosneft Share Swap 
Agreement and the Arctic Opportunity, originally announced on 14 January 
2011, had terminated. This termination was as a result of the deadline 
for the satisfaction of conditions precedent having expired following 
delays resulting from the interim orders referred to above. These interim 
orders did not address the question of whether or not BP breached the 
Shareholders Agreement. The arbitration proceedings, which are subject to 
strict confidentiality obligations, are ongoing.

Five minority shareholders of OAO TNK-BP Holding (TBH) have 

filed two civil actions in Tyumen, Siberia, against BP Russia Investments 
Limited and BP p.l.c. and against two of the BP nominated directors 
of TBH. These two actions sought to recover alleged losses to TBH 
of $13 billion and $2.7 billion respectively. On 11 November 2011, 
the Tyumen Court dismissed both claims fully on their merits. The 
shareholders appealed both of these decisions to the Omsk Appellate 
court. On 26 January 2012, the Appellate court upheld the Tyumen Court’s 
dismissal of the claim in relation to the BP nominated directors of TBH. The 
Omsk Appellate court subsequently confirmed the Tyumen court of first 
instance’s dismissal of the minority suits against BP Russia Investments 
Limited and BP p.l.c. BP believes the allegations made are wholly without 
merit. No losses have been incurred and BP believes the likelihood of the 
claims being ultimately successful is remote. Consequently no amounts 
have been provided and the claim is not disclosed as a contingent liability.

On 9 February 2011, Apache Canada Ltd (Apache) commenced 

an arbitration against BP Canada Energy. Apache alleges that various 
properties/sites in respect of which it acquired interests from BP Canada 
Energy pursuant to the parties’ Purchase and Sale Agreement signed in 
July 2010 will require work to bring the properties/sites into compliance 
with applicable environmental laws, and Apache claims that the purchase 
price should be adjusted for its estimated possible costs. BP Canada 
Energy denies such costs will arise or require any adjustment to the 
purchase price. The parties have appointed the arbitrator, and currently 
the hearing on the merits is scheduled to commence during the second 
quarter of 2012.

On 24 January 2012, the Republic of Bolivia issued a press 
statement declaring its intent to nationalize Pan American Energy’s 
interests in the Caipipendi Operations Contract. No formal nationalization 
process has yet commenced. Pan American Energy and its shareholders 
BP and Bridas intend to vigorously defend their legal interests under the 
Caipipendi Operations Contract and available Bilateral Investment Treaties.

complaint in the False Claims Act lawsuit seeking an injunction shutting 
down the Atlantis platform. The court denied BP’s motion to dismiss 
the complaint in March 2011. Separately, also in March 2011, BOEMRE 
issued its investigation report of the Abbott Atlantis allegations, which 
concluded that Mr Abbott’s allegations that Atlantis operations personnel 
lacked access to critical, engineer-approved drawings were without merit 
and that his allegations about false submissions by BP to BOEMRE were 
unfounded. Trial is scheduled to begin on 10 April 2012.

BP Products’ US refineries are subject to a 2001 consent 
decree with the EPA that resolved alleged violations of the CAA, 
and implementation of the decree’s requirements continues. A 2009 
amendment to the decree resolves remaining alleged air violations at 
the Texas City refinery through the payment of a $12-million civil fine, 
a $6-million supplemental environmental project and enhanced CAA 
compliance measures estimated to cost approximately $150 million. The 
fine has been paid, and BP Products is implementing the other provisions.
On 30 September 2010, the EPA and BP Products lodged a  

civil consent decree with the federal court in Houston. Following a 
public comment period, the federal court approved the settlement on 
30 December 2010. The decree resolves allegations of civil violations of 
the risk management planning regulations promulgated under the CAA that 
are alleged to have occurred in 2004 and 2005 at the Texas City refinery. 
BP Products has paid the $15-million civil penalty and the Texas City 
refinery is implementing requirements to enhance reporting to  
the EPA regarding employee training, equipment inspection and  
incident investigation.

Various environmental groups and the EPA have challenged 

certain aspects of the air permits issued by the Indiana Department of 
Environmental Management (IDEM) for upgrades to the Whiting refinery. 
In response to these challenges, the IDEM has reviewed the permits and 
responded formally to the EPA. BP is in discussions with the EPA, the 
IDEM and certain environmental groups over these and other CAA issues 
relating to the Whiting refinery. BP has also been in settlement discussions 
with EPA to resolve alleged CAA violations at the Toledo, Carson and 
Cherry Point refineries.

An application was brought in the English High Court on 1 February 

2011 by Alfa Petroleum Holdings Limited and OGIP Ventures Limited 
against BP International Limited and BP Russian Investments Limited 
alleging breach of a Shareholders Agreement on the part of BP and 
seeking an interim injunction restraining BP from taking steps to conclude, 
implement or perform the transactions with Rosneft Oil Company, 
originally announced on 14 January 2011, relating to oil and gas exploration, 
production, refining and marketing in Russia (the Arctic Opportunity). 
Those transactions included the issue or transfer of shares between 
Rosneft Oil Company and any BP group company (pursuant to the Rosneft 
Share Swap Agreement). The court granted an interim order restraining 
BP from taking any further steps in relation to the Rosneft transactions 
pending an expedited UNCITRAL arbitration procedure in accordance with 
the Shareholders Agreement between the parties. The arbitration has 
commenced and the interim injunction was continued by the arbitration 
panel.

BP has contractual and other arrangements with numerous third parties in 
support of its business activities. This report does not contain information 
about any of these third parties as none of our arrangements with them are 
considered to be essential to the business of BP.

Suppliers and contractors
Our processes are designed to enable us to choose suppliers carefully 
on merit, avoiding conflicts of interest and inappropriate gifts and 
entertainment. We expect suppliers to comply with legal requirements 
and we seek to do business with suppliers who act in line with BP’s 
commitments to compliance and ethics, as outlined in our code of conduct. 
We engage with suppliers in a variety of ways, including performance 
review meetings to identify mutually advantageous ways to improve 
performance.

Creditor payment policy and practice
Statutory regulations issued under the UK Companies Act 2006 require 
companies to make a statement of their policy and practice in respect 
of the payment of trade creditors. In view of the international nature of 
the group’s operations there is no specific group-wide policy in respect 
of payments to suppliers. Relationships with suppliers are, however, 
governed by the group’s policy commitment to long-term relationships 
founded on trust and mutual advantage. Within this overall policy, individual 
operating companies are responsible for agreeing terms and conditions for 
their business transactions and ensuring that suppliers are aware of the 
terms of payment.

Share prices and listings

Markets and market prices
The primary market for BP’s ordinary shares is the London Stock Exchange 
(LSE). BP’s ordinary shares are a constituent element of the Financial 
Times Stock Exchange 100 Index. BP’s ordinary shares are also traded on 
the Frankfurt Stock Exchange in Germany.

Trading of BP’s shares on the LSE is primarily through the use of 

the Stock Exchange Electronic Trading Service (SETS), introduced in 1997 
for the largest companies in terms of market capitalization whose primary 
listing is the LSE. Under SETS, buy and sell orders at specific prices may 
be sent electronically to the exchange by any firm that is a member of the 
LSE, on behalf of a client or on behalf of itself acting as a principal. The 
orders are then anonymously displayed in the order book. When there is 
a match on a buy and a sell order, the trade is executed and automatically 
reported to the LSE. Trading is continuous from 8.00 a.m. to 4.30 p.m. UK 
time but, in the event of a 20% movement in the share price either way, 
the LSE may impose a temporary halt in the trading of that company’s 
shares in the order book to allow the market to re-establish equilibrium. 
Dealings in ordinary shares may also take place between an investor and a 
market-maker, via a member firm, outside the electronic order book.

In the US, the company’s securities are traded on the New York 

Stock Exchange (NYSE) in the form of ADSs, for which JPMorgan Chase 
Bank, N.A. is the depositary (the Depositary) and transfer agent. The 
Depositary’s principal office is 1 Chase Manhattan Plaza, N.A., Floor 21, 
New York, NY 10005-1401, US. Each ADS represents six ordinary shares. 
ADSs are listed on the New York Stock Exchange. ADSs are evidenced 
by American depositary receipts (ADRs), which may be issued in either 
certificated or book entry form.

The following table sets forth for the periods indicated the highest 
and lowest middle market quotations for BP’s ordinary shares and ADSs 
for the periods shown. These are derived from the highest and lowest 
sales prices as reported on the LSE and NYSE, respectively.

Market prices for the ordinary shares on the LSE and in after-hours trading 
off the LSE, in each case while the NYSE is open, and the market prices for 
ADSs on the NYSE, are closely related due to arbitrage among the various 
markets, although differences may exist from time to time due to various 
factors, including UK stamp duty reserve tax.

On 17 February 2012, 838,650,908 ADSs (equivalent to 

approximately 5,031,905,448 ordinary shares or some 26.51% of the total 
issued share capital, excluding shares held in treasury) were outstanding 
and were held by approximately 109,640 ADS holders. Of these, about 
108,369 had registered addresses in the US at that date. One of the 
registered holders of ADSs represents some 811,108 underlying holders.
On 17 February 2012, there were approximately 303,020 holders 

of record of ordinary shares. Of these holders, around 1,585 had registered 
addresses in the US and held a total of some 4,331,996 ordinary shares.

Since certain of the ordinary shares and ADSs were held by brokers 

and other nominees, the number of holders of record in the US may not 
be representative of the number of beneficial holders or of their country of 
residence.

Material contracts

On 6 August 2010, BP entered into a trust agreement with John S Martin, 
Jr and Kent D Syverud, as individual trustees, and Citigroup Trust-Delaware, 
N.A., as corporate trustee (the Trust Agreement) which established the 
Deepwater Horizon Oil Spill Trust (the Trust) to be funded in the amount of 
$20 billion (the trust fund) over the period to the fourth quarter of 2013. The 
trust fund is available to satisfy legitimate individual and business claims 
administered by the Gulf Coast Claims Facility (GCCF), state and local 
government claims resolved by BP, final judgments and settlements, state 
and local response costs, and natural resource damages and related costs. 
Fines, penalties and claims administration costs are not covered by the trust 
fund. Under the terms of the Trust Agreement, BP has no right to access 
the funds once they have been contributed to the trust fund. BP will receive 
funds from the trust fund only upon its expiration, if there are any funds 
remaining at that point. BP has the authority under the Trust Agreement to 
present certain resolved claims, including natural resource damages claims 
and state and local response claims, to the Trust for payment, by providing 
the trustees with all the required documents establishing that such claims 
are valid under the Trust Agreement. However, any such payments can 
only be made on the authority of the trustee and any funds distributed are 
paid directly to the claimants, not to BP. The Trust Agreement is governed 
by the laws of the State of Delaware.

On 30 September 2010, BP entered a pledge and collateral 
agreement in favour of John S Martin, Jr and Kent D Syverud (the Pledge 
Agreement), which pledged certain Gulf of Mexico assets as collateral 
for the trust fund funding obligation. The pledged collateral consists of an 
overriding royalty interest in oil and gas production of BP’s Thunder Horse, 
Atlantis, Mad Dog, Great White and Mars, Ursa and Na Kika assets in the 
Gulf of Mexico. A wholly-owned company called Verano Collateral Holdings 
LLC (Verano) has been created to hold the overriding royalty interest, which 
was capped at $1.25 billion per quarter and $17 billion in total. Verano 
pledged the overriding royalty interest to the Trust as collateral for BP’s 
remaining contribution obligations to the Trust. An event of default under 
the Pledge Agreement arose if BP failed to make any contribution under 
the Trust Agreement when due or otherwise failed to observe certain other 
obligations, subject to specified cure periods. Following an event of default, 
the trustees were entitled to exercise all remedies as secured parties in 
respect of the collateral, including receipt of royalty interests from the 
pledged assets, having all or part of the limited liability company interests 
registered in the trustees’ name and selling the collateral at public or 
private sale. The Pledge Agreement was governed by the laws of the State 
of Texas. On 9 November 2011 the Pledge Agreement and the related 
overriding royalty interest conveyance and mortgage were amended and 
restated (such documents collectively referred to as the Amended and 
Restated Pledge Agreement) to change the overriding royalty interest 
effective as of 1 October 2011 to $14.7 billion. Beginning on 2 January 
2012, and on the first business day of each subsequent calendar quarter, 
the overriding royalty interest is recalculated as the remaining outstanding 
contributions owed by BP to the Trust as of that date multiplied by a factor 

168    BP Annual Report and Form 20-F 2011

of 1.45. On 2 January 2012 the overriding royalty interest was recalculated 
as $7.1 billion. The Amended and Restated Pledge Agreement also 
changed the definition of an event of default to be a failure by BP to make 
required payments pursuant to the terms of the Trust Agreement.

Exchange controls

There are currently no UK foreign exchange controls or restrictions on 
remittances of dividends on the ordinary shares or on the conduct of the 
company’s operations.

There are no limitations, either under the laws of the UK or under 
the company’s Articles of Association, restricting the right of non-resident 
or foreign owners to hold or vote BP ordinary or preference shares in the 
company.

Taxation

This section describes the material US federal income tax and UK taxation 
consequences of owning ordinary shares or ADSs to a US holder who 
holds the ordinary shares or ADSs as capital assets for tax purposes. 
It does not apply, however, to members of special classes of holders 
subject to special rules and holders that, directly or indirectly, hold 10% 
or more of the company’s voting stock. In addition, if a partnership holds 
the shares or ADSs, the US federal income tax treatment of a partner will 
generally depend on the status of the partner and the tax treatment of the 
partnership and may not be described fully below.

A US holder is any beneficial owner of ordinary shares or ADSs that 

is for US federal income tax purposes (i) a citizen or resident of the US, (ii) 
a US domestic corporation, (iii) an estate whose income is subject to US 
federal income taxation regardless of its source, or (iv) a trust if a US court 
can exercise primary supervision over the trust’s administration and one or 
more US persons are authorized to control all substantial decisions of the 
trust.

This section is based on the Internal Revenue Code of 1986, 
as amended, its legislative history, existing and proposed regulations 
thereunder, published rulings and court decisions, and the taxation laws 
of the UK, all as currently in effect, as well as the income tax convention 
between the US and the UK that entered into force on 31 March 2003 
(the ‘Treaty’). These laws are subject to change, possibly on a retroactive 
basis. This section is further based in part on the representations of the 
Depositary and assumes that each obligation in the Deposit Agreement 
and any related agreement will be performed in accordance with its terms.

For purposes of the Treaty and the estate and gift tax Convention 

(the ‘Estate Tax Convention’,) and for US federal income tax and UK 
taxation purposes, a holder of ADRs evidencing ADSs will be treated as 
the owner of the company’s ordinary shares represented by those ADRs. 
Exchanges of ordinary shares for ADRs and ADRs for ordinary shares 
generally will not be subject to US federal income tax or to UK taxation 
other than stamp duty or stamp duty reserve tax, as described below.

Investors should consult their own tax adviser regarding the US 
federal, state and local, UK and other tax consequences of owning and 
disposing of ordinary shares and ADSs in their particular circumstances, 
and in particular whether they are eligible for the benefits of the Treaty.

Taxation of dividends
UK taxation
Under current UK taxation law, no withholding tax will be deducted from 
dividends paid by the company, including dividends paid to US holders. 
A shareholder that is a company resident for tax purposes in the UK 
or trading in the UK through a permanent establishment generally will 
not be taxable in the UK on a dividend it receives from the company. A 
shareholder who is an individual resident for tax purposes in the UK is 
subject to UK tax but entitled to a tax credit on cash dividends paid on 
ordinary shares or ADSs of the company equal to one-ninth of the  
cash dividend.

Additional information for shareholdersUS federal income taxation
A US holder is subject to US federal income taxation on the gross amount 
of any dividend paid by the company out of its current or accumulated 
earnings and profits (as determined for US federal income tax purposes). 
Dividends paid to a non-corporate US holder in taxable years beginning 
before 1 January 2013 that constitute qualified dividend income will be 
taxable to the holder at a maximum tax rate of 15%, provided that the 
holder has a holding period in the ordinary shares or ADSs of more than 
60 days during the 121-day period beginning 60 days before the ex-
dividend date and meets other holding period requirements. Dividends 
paid by the company with respect to the shares or ADSs will generally be 
qualified dividend income.

As noted above in UK taxation, a US holder will not be subject to 

UK withholding tax. A US holder will include in gross income for US federal 
income tax purposes the amount of the dividend actually received from the 
company, and the receipt of a dividend will not entitle the US holder to a 
foreign tax credit.

For US federal income tax purposes, a dividend must be included 

in income when the US holder, in the case of ordinary shares, or the 
Depositary, in the case of ADSs, actually or constructively receives the 
dividend and will not be eligible for the dividends-received deduction 
generally allowed to US corporations in respect of dividends received from 
other US corporations. Dividends will be income from sources outside the 
US and generally will be ‘passive category income’ or, in the case of certain 
US holders, ‘general category income’, each of which is treated separately 
for purposes of computing a US holder’s foreign tax credit limitation.

The amount of the dividend distribution on the ordinary shares 

or ADSs that is paid in pounds sterling will be the US dollar value of the 
pounds sterling payments made, determined at the spot pounds sterling/ 
US dollar rate on the date the dividend distribution is includible in income, 
regardless of whether the payment is, in fact, converted into US dollars. 
Generally, any gain or loss resulting from currency exchange fluctuations 
during the period from the date the pounds sterling dividend payment is 
includible in income to the date the payment is converted into US dollars 
will be treated as ordinary income or loss and will not be eligible for the 
15% tax rate on qualified dividend income. The gain or loss generally 
will be income or loss from sources within the US for foreign tax credit 
limitation purposes.

Distributions in excess of the company’s earnings and profits, as 

determined for US federal income tax purposes, will be treated as a return 
of capital to the extent of the US holder’s basis in the ordinary shares or 
ADSs and thereafter as capital gain, subject to taxation as described in 
Taxation of capital gains – US federal income taxation section below.

In addition, the taxation of dividends may be subject to the rules 

for passive foreign investment companies (PFIC), described below under 
‘Taxation of capital gains – US federal income taxation’. Distributions made 
by a PFIC do not constitute qualified dividend income and are not eligible 
for the 15% tax rate.

Taxation of capital gains
UK taxation
A US holder may be liable for both UK and US tax in respect of a gain 
on the disposal of ordinary shares or ADSs if the US holder is (i) a citizen 
of the US resident or ordinarily resident in the UK, (ii) a US domestic 
corporation resident in the UK by reason of its business being managed or 
controlled in the UK or (iii) a citizen of the US or a corporation that carries 
on a trade or profession or vocation in the UK through a branch or agency 
or, in respect of corporations for accounting periods beginning on or 
after 1 January 2003, through a permanent establishment, and that have 
used, held, or acquired the ordinary shares or ADSs for the purposes of 
such trade, profession or vocation of such branch, agency or permanent 
establishment. However, such persons may be entitled to a tax credit 
against their US federal income tax liability for the amount of UK capital 
gains tax or UK corporation tax on chargeable gains (as the case may be) 
that is paid in respect of such gain.

Under the Treaty, capital gains on dispositions of ordinary shares or ADSs 
generally will be subject to tax only in the jurisdiction of residence of the 
relevant holder as determined under both the laws of the UK and the US 
and as required by the terms of the Treaty.

Under the Treaty, individuals who are residents of either the UK or 

the US and who have been residents of the other jurisdiction (the US or 
the UK, as the case may be) at any time during the six years immediately 
preceding the relevant disposal of ordinary shares or ADSs may be subject 
to tax with respect to capital gains arising from a disposition of ordinary 
shares or ADSs of the company not only in the jurisdiction of which 
the holder is resident at the time of the disposition but also in the other 
jurisdiction.

US federal income taxation
A US holder who sells or otherwise disposes of ordinary shares or ADSs 
will recognize a capital gain or loss for US federal income tax purposes 
equal to the difference between the US dollar value of the amount realized 
and the holder’s tax basis, determined in US dollars, in the ordinary shares 
or ADSs. Any capital gain of a non-corporate US holder is generally taxed at 
preferential rates if the holder’s holding period for such ordinary shares or 
ADSs exceeds one year. The gain or loss will generally be income or loss 
from sources within the US for foreign tax credit limitation purposes. The 
deductibility of capital losses is subject to limitations.

We do not believe that ordinary shares or ADSs will be treated as 

stock of a passive foreign investment company, or PFIC, for US federal 
income tax purposes, but this conclusion is a factual determination that 
is made annually and thus is subject to change. If we are treated as a 
PFIC, unless a US holder elects to be taxed annually on a mark-to-market 
basis with respect to ordinary shares or ADSs, any gain realized on the 
sale or other disposition of ordinary shares or ADSs would in general not 
be treated as capital gain. Instead, a US holder would be treated as if he 
or she had realized such gain rateably over the holding period for ordinary 
shares or ADSs and would be taxed at the highest tax rate in effect for 
each such year to which the gain was allocated, in addition to which an 
interest charge in respect of the tax attributable to each such year would 
apply. Certain ‘excess distributions’ would be similarly treated if we were 
treated as a PFIC.

Additional tax considerations
Scrip Dividend Programme
The company has introduced an optional Scrip Dividend Programme, 
wherein holders of ordinary shares or ADSs may elect to receive any 
dividends in the form of new, fully-paid ordinary shares or ADSs of 
the company, instead of cash. Please consult your tax adviser for the 
consequences to you.

UK inheritance tax
The Estate Tax Convention applies to inheritance tax. ADSs held by an 
individual who is domiciled for the purposes of the Estate Tax Convention 
in the US and is not for the purposes of the Estate Tax Convention 
a national of the UK will not be subject to UK inheritance tax on the 
individual’s death or on transfer during the individual’s lifetime unless, 
among other things, the ADSs are part of the business property of a 
permanent establishment situated in the UK used for the performance of 
independent personal services. In the exceptional case where ADSs are 
subject to both inheritance tax and US federal gift or estate tax, the Estate 
Tax Convention generally provides for tax payable in the US to be credited 
against tax payable in the UK or for tax paid in the UK to be credited against 
tax payable in the US, based on priority rules set forth in the Estate Tax 
Convention.

practice of HM Revenue & Customs in the UK under existing law.

dividend not been made. ADR holders electing to receive ADSs instead of 
the cash dividend authorize the Depositary to sell sufficient shares to cover 
this liability.

Provided that any instrument of transfer is not executed in the UK 

and remains at all times outside the UK and the transfer does not relate 
to any matter or thing done or to be done in the UK, no UK stamp duty is 
payable on the acquisition or transfer of ADSs. Neither will an agreement 
to transfer ADSs in the form of ADRs give rise to a liability to stamp duty 
reserve tax.

Purchases of ordinary shares, as opposed to ADSs, through the 

CREST system of paperless share transfers will be subject to stamp duty 
reserve tax at 0.5%. The charge will arise as soon as there is an agreement 
for the transfer of the shares (or, in the case of a conditional agreement, 
when the condition is fulfilled). The stamp duty reserve tax will apply to 
agreements to transfer ordinary shares even if the agreement is made 
outside the UK between two non-residents. Purchases of ordinary shares 
outside the CREST system are subject either to stamp duty at a rate of £5 
per £1,000 (or part, unless the stamp duty is less than £5, when no stamp 
duty is charged), or stamp duty reserve tax at 0.5%. Stamp duty and stamp 
duty reserve tax are generally the liability of the purchaser.

A subsequent transfer of ordinary shares to the Depositary’s 

nominee will give rise to further stamp duty at the rate of £1.50 per £100 
(or part) or stamp duty reserve tax at the rate of 1.5% of the value of the 
ordinary shares at the time of the transfer. An ADR holder electing to 
receive ADSs instead of a cash dividend will be responsible for the stamp 
duty reserve tax due on issue of shares to the Depositary’s nominee 
and calculated at the rate of 1.5% on the issue price of the shares. It is 
understood that HM Revenue & Customs practice is to calculate the issue 
price by reference to the total cash receipt to which a US holder would 
have been entitled had the election to receive ADSs instead of a cash

Statement of directors’ responsibilities

The directors are responsible for preparing the Annual Report and the financial statements in accordance with applicable law and regulations.

The directors are required by the UK Companies Act 2006 to prepare financial statements for each financial year that give a true and fair view 
of the financial position of the group and the parent company and the financial performance and cash flows of the group and parent company for that 
period. Under that law they are required to prepare the consolidated financial statements in accordance with International Financial Reporting Standards 
(IFRS) as adopted by the European Union (EU) and applicable law and have elected to prepare the parent company financial statements in accordance 
with applicable United Kingdom law and United Kingdom accounting standards (United Kingdom generally accepted accounting practice). In preparing the 
consolidated financial statements the directors have also elected to comply with IFRSs as issued by the International Accounting Standards Board (IASB). 
In preparing those financial statements, the directors are required to:
•	 Select suitable accounting policies and then apply them consistently.
•	 Make judgements and estimates that are reasonable and prudent.
•	 Present information, including accounting policies, in a manner that provides relevant, reliable, comparable and understandable information.
•	 Provide additional disclosure when compliance with the specific requirements of IFRS is insufficient to enable users to understand the impact of 

particular transactions, other events and conditions on the group’s financial position and financial performance.

•	 State that applicable accounting standards have been followed, subject to any material departures disclosed and explained in the parent company 

financial statements.

•	 Prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.
The directors are responsible for keeping proper accounting records that disclose with reasonable accuracy at any time the financial position of the 
group and company and enable them to ensure that the consolidated financial statements comply with the Companies Act 2006 and Article 4 of the IAS 
Regulation and the parent company financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of 
the group and company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

The directors draw attention to Notes 2, 36 and 43 on the consolidated financial statements which describe the uncertainties surrounding the 

amounts and timings of liabilities arising from the Gulf of Mexico oil spill.

The group’s business activities, performance, position and risks are set out in this report. The financial position of the group, its cash flows, 

liquidity position and borrowing facilities are detailed in the appropriate sections on pages 103 to 106 and elsewhere in the notes on the consolidated 
financial statements. The report also includes details of the group’s risk mitigation and management. Information on the Gulf of Mexico oil spill and BP’s 
response is included on pages 76 to 79 and elsewhere in this report, including Safety on pages 65 to 69. The group has considerable financial resources, 
and the directors believe that the group is well placed to manage its business risks successfully. After making enquiries, the directors have a reasonable 
expectation that the company and the group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they 
continue to adopt the going concern basis in preparing the annual report and accounts.

Having made the requisite enquiries, so far as the directors are aware, there is no relevant audit information (as defined by Section 418(3) of 

the Companies Act 2006) of which the company’s auditors are unaware, and the directors have taken all the steps they ought to have taken to make 
themselves aware of any relevant audit information and to establish that the company’s auditors are aware of that information.

The directors confirm that to the best of their knowledge:

•	 The consolidated financial statements, prepared in accordance with IFRS as issued by the IASB, IFRS as adopted by the EU and in accordance with the 

provisions of the Companies Act 2006, give a true and fair view of the assets, liabilities, financial position and profit or loss of the group;

•	 The parent company financial statements, prepared in accordance with United Kingdom generally accepted accounting practice, give a true and fair 

view of the assets, liabilities, financial position, performance and cash flows of the company; and

•	 The management report, which is incorporated in the directors’ report, includes a fair review of the development and performance of the business and 

the position of the group, together with a description of the principal risks and uncertainties.

Consolidated financial statements of the BP groupConsolidated financial statements of the BP group

Independent auditor’s report on the Annual Report and Accounts  
to the members of BP p.l.c.

We have audited the consolidated financial statements of BP p.l.c. for the year ended 31 December 2011 which comprise the group income statement, 
the group statement of comprehensive income, the group statement of changes in equity, the group balance sheet, the group cash flow statement 
and the related notes 1 to 45. The financial reporting framework that has been applied in their preparation is applicable law and International Financial 
Reporting Standards (IFRS) as adopted by the European Union.

This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit 

work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor’s report 
and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the 
company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

Respective responsibilities of directors and auditor
As explained more fully in the Statement of directors’ responsibilities set out on page 174, the directors are responsible for the preparation of the 
consolidated financial statements and for being satisfied that they give a true and fair view. Our responsibility is to audit and express an opinion on the 
consolidated financial statements in accordance with applicable law and International Standards on Auditing (UK and Ireland). Those standards require us 
to comply with the Auditing Practices Board’s Ethical Standards for Auditors.

Scope of the audit of the financial statements
An audit involves obtaining evidence about the amounts and disclosures in the financial statements sufficient to give reasonable assurance that the 
financial statements are free from material misstatement, whether caused by fraud or error. This includes an assessment of: whether the accounting 
policies are appropriate to the group’s circumstances and have been consistently applied and adequately disclosed; the reasonableness of significant 
accounting estimates made by the directors; and the overall presentation of the financial statements. In addition, we read all the financial and non-financial 
information in the annual report to identify material inconsistencies with the audited financial statements. If we become aware of any apparent material 
misstatements or inconsistencies we consider the implications for our report.

Opinion on financial statements
In our opinion the consolidated financial statements:
•	 give a true and fair view of the state of the group’s affairs as at 31 December 2011 and of its profit for the year then ended;
•	 have been properly prepared in accordance with IFRS as adopted by the European Union; and
•	 have been prepared in accordance with the requirements of the Companies Act 2006 and Article 4 of the IAS Regulation.

Separate opinion in relation to IFRS as issued by the International Accounting Standards Board
As explained in Note 1 to the consolidated financial statements, the group in addition to applying IFRS as adopted by the European Union, has also applied 
IFRS as issued by the International Accounting Standards Board (IASB).

In our opinion the consolidated financial statements comply with IFRS as issued by the IASB.

Emphasis of matter – significant uncertainty over provisions and contingencies related to the Gulf of Mexico oil spill
In forming our opinion we have considered the adequacy of the disclosures made in Notes 2, 36 and 43 to the financial statements concerning the 
provisions, future expenditures for which reliable estimates cannot be made and other contingencies related to the Gulf of Mexico oil spill significant 
event. The total amounts that will ultimately be paid by BP in relation to all obligations relating to the incident are subject to significant uncertainty and the 
ultimate exposure and cost to BP will be dependent on many factors, including any determination of BP’s culpability based on any findings of negligence, 
gross negligence or wilful misconduct. Actual costs could ultimately be significantly higher or lower than those recorded in relation to all obligations 
relating to the oil spill. Our opinion is not qualified in respect of these matters.

Opinion on other matter prescribed by the Companies Act 2006
In our opinion the information given in the Directors’ Report for the financial year for which the consolidated financial statements are prepared is 
consistent with the consolidated financial statements.

Matters on which we are required to report by exception
We have nothing to report in respect of the following:
Under the Companies Act 2006 we are required to report to you if, in our opinion:
•	 certain disclosures of directors’ remuneration specified by law are not made; or
•	 we have not received all the information and explanations we require for our audit.

Under the Listing Rules we are required to review:
•	 the directors’ statement, set out on page 174, in relation to going concern;
•	 the part of the BP board performance report relating to the company’s compliance with the nine provisions of the UK Corporate Governance Code 

specified for our review; and

•	 certain elements of the report to shareholders by the Board on directors’ remuneration.

Other matter
We have reported separately on the parent company financial statements of BP p.l.c. for the year ended 31 December 2011 and on the information in the 
Directors’ Remuneration Report that is described as having been audited.

Financial statementsConsolidated financial statements of the BP groupReport of Independent Registered Public Accounting Firm on the  
Annual Report on Form 20-F

The Board of Directors and Shareholders of BP p.l.c.
We have audited the accompanying group balance sheets of BP p.l.c. as of 31 December 2011 and 2010, and the related group income statement, group 
statement of comprehensive income, group statement of changes in equity and group cash flow statement for each of the three years in the period 
ended 31 December 2011. These financial statements are the responsibility of the company’s management. Our responsibility is to express an opinion 
on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards 
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An 
audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing 
the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We 
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the group financial position of BP p.l.c. at 31 December 

2011 and 2010, and the group results of operations and cash flows for each of the three years in the period ended 31 December 2011, in accordance with 
International Financial Reporting Standards as adopted by the European Union and International Financial Reporting Standards as issued by the International 
Accounting Standards Board.

In forming our opinion we have considered the adequacy of the disclosures made in Notes 2, 36 and 43 to the financial statements concerning 

the provisions, future expenditures for which reliable estimates cannot be made and other contingencies related to the Gulf of Mexico oil spill significant 
event. The total amounts that will ultimately be paid by BP in relation to all obligations relating to the incident are subject to significant uncertainty and the 
ultimate exposure and cost to BP will be dependent on many factors, including any determination of BP’s culpability based on any findings of negligence, 
gross negligence or wilful misconduct. Actual costs could ultimately be significantly higher or lower than those recorded in relation to all obligations 
relating to the oil spill. Our opinion is not qualified in respect of these matters.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), BP p.l.c.’s internal 

control over financial reporting as of 31 December 2011, based on criteria established in the Internal Control: Revised Guidance for Directors on the 
Combined Code (Turnbull) as issued by the Institute of Chartered Accountants in England and Wales (the Turnbull criteria) and our report dated 6 March 
2012 expressed an unqualified opinion thereon.

176    BP Annual Report and Form 20-F 2011

Consolidated financial statements of the BP groupReport of Independent Registered Public Accounting Firm on the  
Annual Report on Form 20-F

The Board of Directors and Shareholders of BP p.l.c.
We have audited BP p.l.c.’s internal control over financial reporting as of 31 December 2011, based on criteria established in Internal Control: Revised 
Guidance for Directors on the Combined Code (Turnbull) as issued by the Institute of Chartered Accountants in England and Wales (the Turnbull criteria). 
BP p.l.c.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of 
internal control over financial reporting included in the accompanying Management’s report on internal control over financial reporting on page 135. Our 
responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards 

require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained 
in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other 
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s 
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 

evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the 
degree of compliance with the policies or procedures may deteriorate.

In our opinion, BP p.l.c. maintained, in all material respects, effective internal control over financial reporting as of 31 December 2011, based on the 

Turnbull criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the group balance 

sheets of BP p.l.c. as of 31 December 2011 and 2010, and the related group income statement, group statement of comprehensive income, group 
statement of changes in equity and group cash flow statement for each of the three years in the period ended 31 December 2011, and our report dated 
6 March 2012 expressed an unqualified opinion thereon.

Notes on financial statements

1. Significant accounting policies

Authorization of financial statements and statement of compliance 
with International Financial Reporting Standards
The consolidated financial statements of the BP group for the year ended 
31 December 2011 were approved and signed by the chairman and group 
chief executive on 6 March 2012 having been duly authorized to do so by 
the board of directors. BP p.l.c. is a public limited company incorporated and 
domiciled in England and Wales. The consolidated financial statements have 
been prepared in accordance with International Financial Reporting Standards 
(IFRS) as issued by the International Accounting Standards Board (IASB), 
IFRS as adopted by the European Union (EU) and in accordance with the 
provisions of the Companies Act 2006. IFRS as adopted by the EU differs in 
certain respects from IFRS as issued by the IASB, however, the differences 
have no impact on the group’s consolidated financial statements for the 
years presented. The significant accounting policies of the group are set out 
below.

Basis of preparation
The consolidated financial statements have been prepared in accordance 
with IFRS and IFRS Interpretations Committee (IFRIC) interpretations 
issued and effective for the year ended 31 December 2011, or issued and 
early adopted. The standards and interpretations adopted in the year are 
described further on page 188.

The accounting policies that follow have been consistently applied 

to all years presented. The group balance sheet as at 1 January 2010 is 
not presented as it is not affected by the retrospective adoption of any 
new accounting policies during the year, nor any other retrospective 
restatements or reclassifications.

The consolidated financial statements are presented in US dollars 
and all values are rounded to the nearest million dollars ($ million), except 
where otherwise indicated.

For further information regarding the key judgements and estimates 

made by management in applying the group’s accounting policies, refer to 
Critical accounting policies on pages 154 to 157, which forms part of these 
financial statements.

Basis of consolidation
The group financial statements consolidate the financial statements 
of BP p.l.c. and the entities it controls (its subsidiaries) drawn up to 31 
December each year. Control comprises the power to govern the financial 
and operating policies of the investee so as to obtain benefit from its 
activities and is achieved through direct and indirect ownership of voting 
rights; currently exercisable or convertible potential voting rights; or by way 
of contractual agreement. Subsidiaries are consolidated from the date of 
their acquisition, being the date on which the group obtains control, and 
continue to be consolidated until the date that such control ceases. The 
financial statements of subsidiaries are prepared for the same reporting 
year as the parent company, using consistent accounting policies. 
Intercompany balances and transactions, including unrealized profits arising 
from intragroup transactions, have been eliminated. Unrealized losses are 
eliminated unless the transaction provides evidence of an impairment of the 
asset transferred. Minority interests represent the equity in subsidiaries that 
is not attributable, directly or indirectly, to the group.

Segmental reporting
The group’s operating segments are established on the basis of those 
components of the group that are evaluated regularly by the chief operating 
decision maker in deciding how to allocate resources and in assessing 
performance. During the second quarter of 2010 a separate organization 
was created within the group to deal with the ongoing response to the 
Gulf of Mexico oil spill. This organization reports directly to the group 
chief executive officer and its costs are excluded from the results of the 
existing operating segments. Under IFRS its costs are therefore presented 
as a reconciling item between the sum of the results of the reportable 
segments and the group results.

182    BP Annual Report and Form 20-F 2011
182    BP Annual Report and Form 20-F 2011

The accounting policies of the operating segments are the same as the 
group’s accounting policies described in this note, except that IFRS requires 
that the measure of profit or loss disclosed for each operating segment 
is the measure that is provided regularly to the chief operating decision 
maker. For BP, this measure of profit or loss is replacement cost profit 
before interest and tax which reflects the replacement cost of supplies by 
excluding from profit inventory holding gains and losses. Replacement cost 
profit for the group is not a recognized measure under generally accepted 
accounting practice (GAAP). For further information see Note 6.

Interests in joint ventures
A joint venture is a contractual arrangement whereby two or more parties 
(venturers) undertake an economic activity that is subject to joint control. 
Joint control exists only when the strategic financial and operating decisions 
relating to the activity require the unanimous consent of the venturers. A 
jointly controlled entity is a joint venture that involves the establishment of a 
company, partnership or other entity to engage in economic activity that the 
group jointly controls with its fellow venturers.

The results, assets and liabilities of a jointly controlled entity are 

incorporated in these financial statements using the equity method of 
accounting. Under the equity method, the investment in a jointly controlled 
entity is carried in the balance sheet at cost, plus post-acquisition changes 
in the group’s share of net assets of the jointly controlled entity, less 
distributions received and less any impairment in value of the investment. 
Loans advanced to jointly controlled entities that have the characteristics of 
equity financing are also included in the investment on the group balance 
sheet. The group income statement reflects the group’s share of the 
results after tax of the jointly controlled entity.

Financial statements of jointly controlled entities are prepared for 
the same reporting year as the group. Where necessary, adjustments are 
made to those financial statements to bring the accounting policies used 
into line with those of the group.

Unrealized gains on transactions between the group and its jointly 

controlled entities are eliminated to the extent of the group’s interest in the 
jointly controlled entities. Unrealized losses are also eliminated unless the 
transaction provides evidence of an impairment of the asset transferred.
The group assesses investments in jointly controlled entities for 

impairment whenever events or changes in circumstances indicate that the 
carrying value may not be recoverable. If any such indication of impairment 
exists, the carrying amount of the investment is compared with its 
recoverable amount, being the higher of its fair value less costs to sell and 
value in use. Where the carrying amount exceeds the recoverable amount, 
the investment is written down to its recoverable amount.

The group ceases to use the equity method of accounting on the 
date from which it no longer has joint control or significant influence over 
the joint venture or associate respectively, or when the interest becomes 
held for sale.

Certain of the group’s activities, particularly in the Exploration and 

Production segment, are conducted through joint ventures where the 
venturers have a direct ownership interest in, and jointly control, the assets 
of the venture. BP recognizes, on a line-by-line basis in the consolidated 
financial statements, its share of the assets, liabilities and expenses of 
these jointly controlled assets incurred jointly with the other partners, along 
with the group’s income from the sale of its share of the output and any 
liabilities and expenses that the group has incurred in relation to the venture.

Interests in associates
An associate is an entity over which the group is in a position to exercise 
significant influence through participation in the financial and operating 
policy decisions of the investee, but which is not a subsidiary or a jointly 
controlled entity. The results, assets and liabilities of an associate are 
incorporated in these financial statements using the equity method of 
accounting as described above for jointly controlled entities.

Notes on financial statements1. Significant accounting policies continued
Foreign currency translation
The functional currency is the currency of the primary economic environment 
in which an entity operates and is normally the currency in which the entity 
primarily generates and expends cash.

In individual companies, transactions in foreign currencies are initially 

Goodwill may also arise upon investments in jointly controlled entities and 
associates, being the surplus of the cost of investment over the group’s 
share of the net fair value of the identifiable assets. Such goodwill is 
recorded within investments in jointly controlled entities and associates, 
and any impairment of the investment is included within the earnings from 
jointly controlled entities and associates.

recorded in the functional currency by applying the rate of exchange ruling 
at the date of the transaction. Monetary assets and liabilities denominated 
in foreign currencies are retranslated into the functional currency at the 
rate of exchange ruling at the balance sheet date. Any resulting exchange 
differences are included in the income statement. Non-monetary assets 
and liabilities, other than those measured at fair value, are not retranslated 
subsequent to initial recognition.

In the consolidated financial statements, the assets and liabilities 

of non-US dollar functional currency subsidiaries, jointly controlled entities 
and associates, including related goodwill, are translated into US dollars at 
the rate of exchange ruling at the balance sheet date. The results and cash 
flows of non-US dollar functional currency subsidiaries, jointly controlled 
entities and associates are translated into US dollars using average rates 
of exchange. Exchange adjustments arising when the opening net assets 
and the profits for the year retained by non-US dollar functional currency 
subsidiaries, jointly controlled entities and associates are translated into 
US dollars are taken to a separate component of equity and reported in 
the statement of comprehensive income. Exchange gains and losses 
arising on long-term intragroup foreign currency borrowings used to 
finance the group’s non-US dollar investments are also taken to other 
comprehensive income. On disposal or partial disposal of a non-US dollar 
functional currency subsidiary, jointly controlled entity or associate, the 
deferred cumulative amount of exchange gains and losses recognized in 
equity relating to that particular non-US dollar operation is reclassified to 
income statement.

Business combinations and goodwill
A business combination is a transaction or other event in which an acquirer 
obtains control of one or more businesses. A business is an integrated set 
of activities and assets that is capable of being conducted and managed 
for the purpose of providing a return in the form of dividends or lower 
costs or other economic benefits directly to investors or other owners or 
participants. A business consists of inputs and processes applied to those 
inputs that have the ability to create outputs.

Business combinations are accounted for using the acquisition 

method. The identifiable assets acquired and liabilities assumed are 
measured at their fair values at the acquisition date. The cost of an 
acquisition is measured as the aggregate of the consideration transferred, 
measured at acquisition-date fair value, and the amount of any minority 
interest in the acquiree. Minority interests are stated either at fair value 
or at the proportionate share of the recognized amounts of the acquiree’s 
identifiable net assets. Acquisition costs incurred are expensed and 
included in distribution and administration expenses.

Goodwill is initially measured as the excess of the aggregate of the 
consideration transferred, the amount recognized for any minority interest 
and the acquisition-date fair values of any previously held interest in the 
acquiree over the fair value of the identifiable assets acquired and liabilities 
assumed at the acquisition date.

At the acquisition date, any goodwill acquired is allocated to each of 

the cash-generating units, or groups of cash-generating units, expected to 
benefit from the combination’s synergies.

Following initial recognition, goodwill is measured at cost less any 

accumulated impairment losses. Goodwill is reviewed for impairment annually 
or more frequently if events or changes in circumstances indicate that the 
carrying value may be impaired. Impairment is determined by assessing the 
recoverable amount of the cash-generating unit to which the goodwill relates. 
Where the recoverable amount of the cash-generating unit is less than the 
carrying amount, an impairment loss is recognized. An impairment loss 
recognized for goodwill is not reversed in a subsequent period.

Goodwill arising on business combinations prior to 1 January 2003 

is stated at the previous carrying amount, less subsequent impairments, 
under UK generally accepted accounting practice.

Non-current assets held for sale
Non-current assets and disposal groups classified as held for sale are 
measured at the lower of carrying amount and fair value less costs to sell.

Non-current assets and disposal groups are classified as held for 

sale if their carrying amounts will be recovered through a sale transaction 
rather than through continuing use. This condition is regarded as met only 
when the sale is highly probable and the asset or disposal group is available 
for immediate sale in its present condition subject only to terms that are 
usual and customary for sales of such assets. Management must be 
committed to the sale, which should be expected to qualify for recognition 
as a completed sale within one year from the date of classification as held 
for sale.

Property, plant and equipment and intangible assets once classified 

as held for sale are not depreciated. The group ceases to use the equity 
method of accounting on the date from which an interest in a jointly 
controlled entity or an interest in an associate becomes held for sale.

If a non-current asset or disposal group has been classified as held 

for sale, but subsequently ceases to meet the criteria to be classified as 
held for sale, the group ceases to classify the asset or disposal group as 
held for sale. Non-current assets and disposal groups that cease to be 
classified as held for sale are measured at the lower of carrying amount 
before the asset or disposal group was classified as held for sale (adjusted 
for any depreciation, amortization or revaluation that would have been 
recognized had the asset or disposal group not been classified as held for 
sale) and its recoverable amount at the date of the subsequent decision 
not to sell. Except for any interests in equity-accounted entities that cease 
to be classified as held for sale, any adjustment to the carrying amount 
is recognized in profit or loss in the period in which the asset ceases to 
be classified as held for sale. When an interest in an equity-accounted 
entity ceases to be classified as held for sale, it is accounted for using the 
equity method as from the date of its classification as held for sale and the 
financial statements for the periods since classification as held for sale are 
amended accordingly.

Intangible assets
Intangible assets, other than goodwill, include expenditure on the 
exploration for and evaluation of oil and natural gas resources, computer 
software, patents, licences and trademarks and are stated at the amount 
initially recognized, less accumulated amortization and accumulated 
impairment losses. For information on accounting for expenditures on the 
exploration for and evaluation of oil and gas resources, see the accounting 
policy for oil and natural gas exploration, appraisal and development 
expenditure below.

Intangible assets acquired separately from a business are carried 
initially at cost. The initial cost is the aggregate amount paid and the fair 
value of any other consideration given to acquire the asset. An intangible 
asset acquired as part of a business combination is measured at fair value 
at the date of acquisition and is recognized separately from goodwill if the 
asset is separable or arises from contractual or other legal rights.

Intangible assets with a finite life are amortized on a straight-line 

basis over their expected useful lives. For patents, licences and trademarks, 
expected useful life is the shorter of the duration of the legal agreement 
and economic useful life, and can range from three to 15 years. Computer 
software costs generally have a useful life of three to five years.

The expected useful lives of assets are reviewed on an annual basis 

and, if necessary, changes in useful lives are accounted for prospectively.
The carrying value of intangible assets is reviewed for impairment 
whenever events or changes in circumstances indicate the carrying value 
may not be recoverable.

Oil and natural gas exploration, appraisal and development expenditure
Oil and natural gas exploration, appraisal and development expenditure 
is accounted for using the principles of the successful efforts method of 
accounting.

Licence and property acquisition costs
Exploration licence and leasehold property acquisition costs are capitalized 
within intangible assets and are reviewed at each reporting date to confirm 
that there is no indication that the carrying amount exceeds the recoverable 
amount. This review includes confirming that exploration drilling is still 
under way or firmly planned or that it has been determined, or work is 
under way to determine, that the discovery is economically viable based on 
a range of technical and commercial considerations and sufficient progress 
is being made on establishing development plans and timing. If no future 
activity is planned, the remaining balance of the licence and property 
acquisition costs is written off. Lower value licences are pooled and 
amortized on a straight-line basis over the estimated period of exploration. 
Upon recognition of proved reserves and internal approval for development, 
the relevant expenditure is transferred to property, plant and equipment.

Expenditure on major maintenance refits or repairs comprises the cost 
of replacement assets or parts of assets, inspection costs and overhaul 
costs. Where an asset or part of an asset that was separately depreciated 
is replaced and it is probable that future economic benefits associated 
with the item will flow to the group, the expenditure is capitalized and 
the carrying amount of the replaced asset is derecognized. Inspection 
costs associated with major maintenance programmes are capitalized and 
amortized over the period to the next inspection. Overhaul costs for major 
maintenance programmes, and all other maintenance costs are expensed 
as incurred.

Oil and natural gas properties, including related pipelines, are 
depreciated using a unit-of-production method. The cost of producing wells 
is amortized over proved developed reserves. Licence acquisition, common 
facilities and future decommissioning costs are amortized over total proved 
reserves. The unit-of-production rate for the amortization of common 
facilities costs takes into account expenditures incurred to date, together 
with the future capital expenditure expected to be incurred in relation to 
these common facilities.

Other property, plant and equipment is depreciated on a straight 

line basis over its expected useful life. The useful lives of the group’s other 
property, plant and equipment are as follows:

Exploration and appraisal expenditure
Geological and geophysical exploration costs are charged against income 
as incurred. Costs directly associated with an exploration well are initially 
capitalized as an intangible asset until the drilling of the well is complete 
and the results have been evaluated. These costs include employee 
remuneration, materials and fuel used, rig costs and payments made to 
contractors. If potentially commercial quantities of hydrocarbons are not 
found, the exploration well is written off as a dry hole. If hydrocarbons are 
found and, subject to further appraisal activity, are likely to be capable of 
commercial development, the costs continue to be carried as an asset.
Costs directly associated with appraisal activity, undertaken to 

determine the size, characteristics and commercial potential of a reservoir 
following the initial discovery of hydrocarbons, including the costs of 
appraisal wells where hydrocarbons were not found, are initially capitalized 
as an intangible asset.

All such carried costs are subject to technical, commercial and 

management review at least once a year to confirm the continued intent 
to develop or otherwise extract value from the discovery. When this is no 
longer the case, the costs are written off. When proved reserves of oil and 
natural gas are determined and development is approved by management, 
the relevant expenditure is transferred to property, plant and equipment.

Development expenditure
Expenditure on the construction, installation and completion of infrastructure 
facilities such as platforms, pipelines and the drilling of development wells, 
including service and unsuccessful development or delineation wells, is 
capitalized within property, plant and equipment and is depreciated from the 
commencement of production as described below in the accounting policy 
for property, plant and equipment.

Property, plant and equipment
Property, plant and equipment is stated at cost, less accumulated 
depreciation and accumulated impairment losses.

The initial cost of an asset comprises its purchase price or construction 

cost, any costs directly attributable to bringing the asset into operation, the 
initial estimate of any decommissioning obligation, if any, and, for qualifying 
assets, borrowing costs. The purchase price or construction cost is the 
aggregate amount paid and the fair value of any other consideration given 
to acquire the asset. The capitalized value of a finance lease is also included 
within property, plant and equipment. Exchanges of assets are measured 
at fair value unless the exchange transaction lacks commercial substance or 
the fair value of neither the asset received nor the asset given up is reliably 
measurable. The cost of the acquired asset is measured at the fair value 
of the asset given up, unless the fair value of the asset received is more 
clearly evident. Where fair value is not used, the cost of the acquired asset is 
measured at the carrying amount of the asset given up. The gain or loss on 
derecognition of the asset given up is recognized in profit or loss.

The expected useful lives of property, plant and equipment are reviewed on 
an annual basis and, if necessary, changes in useful lives are accounted for 
prospectively.

The carrying amount of property, plant and equipment is reviewed 
for impairment whenever events or changes in circumstances indicate the 
carrying value may not be recoverable.

An item of property, plant and equipment is derecognized upon 

disposal or when no future economic benefits are expected to arise from 
the continued use of the asset. Any gain or loss arising on derecognition of 
the asset (calculated as the difference between the net disposal proceeds 
and the carrying amount of the item) is included in the income statement in 
the period in which the item is derecognized.

Impairment of intangible assets and property, plant and equipment
The group assesses assets or groups of assets for impairment whenever 
events or changes in circumstances indicate that the carrying amount of 
an asset may not be recoverable, for example, low prices or margins for an 
extended period or, for oil and gas assets, significant downward revisions 
of estimated volumes or increases in estimated future development 
expenditure. If any such indication of impairment exists, the group makes an 
estimate of the asset’s recoverable amount. Individual assets are grouped 
for impairment assessment purposes at the lowest level at which there are 
identifiable cash flows that are largely independent of the cash flows of other 
groups of assets. An asset group’s recoverable amount is the higher of its fair 
value less costs to sell and its value in use. Where the carrying amount of an 
asset group exceeds its recoverable amount, the asset group is considered 
impaired and is written down to its recoverable amount. In assessing value in 
use, the estimated future cash flows are adjusted for the risks specific to the 
asset group and are discounted to their present value using a pre-tax discount 
rate that reflects current market assessments of the time value of money.

An assessment is made at each reporting date as to whether there 

is any indication that previously recognized impairment losses may no longer 
exist or may have decreased. If such an indication exists, the recoverable 
amount is estimated. A previously recognized impairment loss is reversed 
only if there has been a change in the estimates used to determine the 
asset’s recoverable amount since the last impairment loss was recognized. 
If that is the case, the carrying amount of the asset is increased to its 
recoverable amount. That increased amount cannot exceed the carrying 
amount that would have been determined, net of depreciation, had no 

Notes on financial statementsAvailable-for-sale financial assets
If an available-for-sale financial asset is impaired, the cumulative loss 
previously recognized in equity is transferred to the income statement. Any 
subsequent recovery in the fair value of the asset is recognized within other 
comprehensive income.

If there is objective evidence that an impairment loss on an 
unquoted equity instrument that is carried at cost has been incurred, the 
amount of the loss is measured as the difference between the asset’s 
carrying amount and the present value of estimated future cash flows 
discounted at the current market rate of return for a similar financial asset.

Inventories
Inventories, other than inventory held for trading purposes, are stated at 
the lower of cost and net realizable value. Cost is determined by the first-in 
first-out method and comprises direct purchase costs, cost of production, 
transportation and manufacturing expenses. Net realizable value is 
determined by reference to prices existing at the balance sheet date.

Inventories held for trading purposes are stated at fair value less 

costs to sell and any changes in net realizable value are recognized in the 
income statement.

Supplies are valued at cost to the group mainly using the average 

method or net realizable value, whichever is the lower.

Financial liabilities
Financial liabilities are classified as financial liabilities at fair value through 
profit or loss; derivatives designated as hedging instruments in an effective 
hedge; or as financial liabilities measured at amortized cost, as appropriate. 
Financial liabilities include trade and other payables, accruals, most items of 
finance debt and derivative financial instruments. The group determines the 
classification of its financial liabilities at initial recognition. The measurement 
of financial liabilities depends on their classification, as follows:

Financial liabilities at fair value through profit or loss
Derivatives, other than those designated as effective hedging instruments, 
are classified as held for trading and are included in this category. These 
liabilities are carried on the balance sheet at fair value with gains or losses 
recognized in the income statement.

Derivatives designated as hedging instruments in an effective hedge
Such derivatives are carried on the balance sheet at fair value. The treatment 
of gains and losses arising from revaluation is described below in the 
accounting policy for derivative financial instruments and hedging activities.

Financial liabilities measured at amortized cost
All other financial liabilities are initially recognized at fair value. For interest-
bearing loans and borrowings this is the fair value of the proceeds received 
net of issue costs associated with the borrowing.

After initial recognition, other financial liabilities are subsequently 

measured at amortized cost using the effective interest method. Amortized 
cost is calculated by taking into account any issue costs, and any discount 
or premium on settlement. Gains and losses arising on the repurchase, 
settlement or cancellation of liabilities are recognized respectively in interest 
and other income and finance costs.

This category of financial liabilities includes trade and other payables 

and finance debt.

1. Significant accounting policies continued
impairment loss been recognized for the asset in prior years. Such reversal 
is recognized in profit or loss. After such a reversal, the depreciation charge 
is adjusted in future periods to allocate the asset’s revised carrying amount, 
less any residual value, on a systematic basis over its remaining useful life.

Financial assets
Financial assets are classified as loans and receivables; available-for-sale 
financial assets; financial assets at fair value through profit or loss; or as 
derivatives designated as hedging instruments in an effective hedge, as 
appropriate. Financial assets include cash and cash equivalents, trade 
receivables, other receivables, loans, other investments, and derivative 
financial instruments. The group determines the classification of its financial 
assets at initial recognition. Financial assets are recognized initially at fair 
value, normally being the transaction price plus, in the case of financial assets 
not at fair value through profit or loss, directly attributable transaction costs.

The subsequent measurement of financial assets depends on their 

classification, as follows:

Loans and receivables
Loans and receivables are non-derivative financial assets with fixed or 
determinable payments that are not quoted in an active market. Such 
assets are carried at amortized cost using the effective interest method if 
the time value of money is significant. Gains and losses are recognized in 
income when the loans and receivables are derecognized or impaired, as 
well as through the amortization process. This category of financial assets 
includes trade and other receivables.

Available-for-sale financial assets
Available-for-sale financial assets are those non-derivative financial assets 
that are not classified as loans and receivables. After initial recognition, 
available-for-sale financial assets are measured at fair value, with gains 
or losses recognized within other comprehensive income. Accumulated 
changes in fair value are recorded as a separate component of equity until 
the investment is derecognized or impaired.

The fair value of quoted investments is determined by reference to 
bid prices at the close of business on the balance sheet date. Where there 
is no active market, fair value is determined using valuation techniques. 
Where fair value cannot be reliably measured, assets are carried at cost.

Financial assets at fair value through profit or loss
Derivatives, other than those designated as effective hedging instruments, 
are classified as held for trading and are included in this category. These 
assets are carried on the balance sheet at fair value with gains or losses 
recognized in the income statement.

Derivatives designated as hedging instruments in an effective hedge
Such derivatives are carried on the balance sheet at fair value. The 
treatment of gains and losses arising from revaluation is described below 
in the accounting policy for derivative financial instruments and hedging 
activities.

Impairment of financial assets
The group assesses at each balance sheet date whether a financial asset or 
group of financial assets is impaired.

Loans and receivables
If there is objective evidence that an impairment loss on loans and 
receivables carried at amortized cost has been incurred, the amount of the 
loss is measured as the difference between the asset’s carrying amount 
and the present value of estimated future cash flows discounted at the 
financial asset’s original effective interest rate. The carrying amount of the 
asset is reduced, with the amount of the loss recognized in the income 
statement.

BP Annual Report and Form 20-F 2011    185

Financial statementsNotes on financial statementsCash flow hedges
For cash flow hedges, the effective portion of the gain or loss on the 
hedging instrument is recognized within other comprehensive income, 
while the ineffective portion is recognized in profit or loss. Amounts taken 
to other comprehensive income are transferred to the income statement 
when the hedged transaction affects profit or loss. The gain or loss 
relating to the effective portion of interest rate swaps hedging variable rate 
borrowings is recognized in the income statement within finance costs.

Where the hedged item is the cost of a non-financial asset or 

liability, such as a forecast transaction for the purchase of property, plant 
and equipment, the amounts recognized within other comprehensive 
income are transferred to the initial carrying amount of the non-financial 
asset or liability.

If the hedging instrument expires or is sold, terminated or exercised 
without replacement or rollover, or if its designation as a hedge is revoked, 
amounts previously recognized within other comprehensive income remain in 
equity until the forecast transaction occurs and are transferred to the income 
statement or to the initial carrying amount of a non-financial asset or liability 
as above. If a forecast transaction is no longer expected to occur, amounts 
previously recognized in equity are reclassified to the income statement.

Embedded derivatives
Derivatives embedded in other financial instruments or other host contracts 
are treated as separate derivatives when their risks and characteristics are 
not closely related to those of the host contract. Contracts are assessed for 
embedded derivatives when the group becomes a party to them, including 
at the date of a business combination. Embedded derivatives are measured 
at fair value at each balance sheet date. Any gains or losses arising from 
changes in fair value are taken directly to the income statement.

Provisions, contingencies and reimbursement assets
Provisions are recognized when the group has a present obligation (legal 
or constructive) as a result of a past event, it is probable that an outflow 
of resources embodying economic benefits will be required to settle 
the obligation and a reliable estimate can be made of the amount of the 
obligation. Where appropriate, the future cash flow estimates are adjusted 
to reflect risks specific to the liability.

If the effect of the time value of money is material, provisions are 

determined by discounting the expected future cash flows at a pre-tax 
risk-free rate that reflects current market assessments of the time value 
of money. Where discounting is used, the increase in the provision due to 
the passage of time is recognized within finance costs. Provisions are split 
between amounts expected to be settled within 12 months of the balance 
sheet date (current) and amounts expected to be settled later (non-current). 
Contingent liabilities are possible obligations whose existence will only be 
confirmed by future events not wholly within the control of the group, or 
present obligations where it is not probable that an outflow of resources 
will be required or the amount of the obligation cannot be measured with 
sufficient reliability.

Contingent liabilities are not recognized in the financial statements 

but are disclosed unless the possibility of an outflow of economic resources 
is considered remote.

Where the group makes contributions into a separately administered 

fund for restoration, environmental or other obligations, which it does 
not control, and the group’s right to the assets in the fund is restricted, 
the obligation to contribute to the fund is recognized as a liability where 
it is probable that such additional contributions will be made. The group 
recognizes a reimbursement asset separately, being the lower of the 
amount of the associated restoration, environmental or other provision and 
the group’s share of the fair value of the net assets of the fund available to 
contributors.

1. Significant accounting policies continued
Leases
Finance leases, which transfer to the group substantially all the risks and 
benefits incidental to ownership of the leased item, are capitalized at the 
commencement of the lease term at the fair value of the leased property 
or, if lower, at the present value of the minimum lease payments. Finance 
charges are allocated to each period so as to achieve a constant rate of 
interest on the remaining balance of the liability and are charged directly 
against income.

Capitalized leased assets are depreciated over the shorter of 

the estimated useful life of the asset or the lease term. Operating lease 
payments are recognized as an expense in the income statement on a 
straight-line basis over the lease term. For both finance and operating 
leases, contingent rents are recognized in the income statement in the 
period in which they are incurred.

Derivative financial instruments and hedging activities
The group uses derivative financial instruments to manage certain 
exposures to fluctuations in foreign currency exchange rates, interest 
rates and commodity prices as well as for trading purposes. Such 
derivative financial instruments are initially recognized at fair value on the 
date on which a derivative contract is entered into and are subsequently 
remeasured at fair value. Derivatives are carried as assets when the fair 
value is positive and as liabilities when the fair value is negative.

Contracts to buy or sell a non-financial item that can be settled net in 
cash or another financial instrument, or by exchanging financial instruments 
as if the contracts were financial instruments, with the exception of 
contracts that were entered into and continue to be held for the purpose 
of the receipt or delivery of a non-financial item in accordance with the 
group’s expected purchase, sale or usage requirements, are accounted for 
as financial instruments.

Gains or losses arising from changes in the fair value of derivatives 
that are not designated as effective hedging instruments are recognized in 
the income statement.

For the purpose of hedge accounting, hedges are classified as:
•	 Fair value hedges when hedging exposure to changes in the fair value of 

a recognized asset or liability.

•	 Cash flow hedges when hedging exposure to variability in cash flows that 
is either attributable to a particular risk associated with a recognized asset 
or liability or a highly probable forecast transaction.

Hedge relationships are formally designated and documented at 
inception, together with the risk management objective and strategy for  
undertaking the hedge. The documentation includes identification of the 
hedging instrument, the hedged item or transaction, the nature of the 
risk being hedged, and how the entity will assess the hedging instrument 
effectiveness in offsetting the exposure to changes in the hedged item’s 
fair value or cash flows attributable to the hedged item. Such hedges 
are expected at inception to be highly effective in achieving offsetting 
changes in fair value or cash flows. Hedges meeting the criteria for hedge 
accounting are accounted for as follows:

Fair value hedges
The change in fair value of a hedging derivative is recognized in profit or loss. 
The change in the fair value of the hedged item attributable to the risk being 
hedged is recorded as part of the carrying value of the hedged item and is 
also recognized in profit or loss.

The group applies fair value hedge accounting for hedging fixed 

interest rate risk on borrowings. The gain or loss relating to the effective 
portion of the interest rate swap is recognized in the income statement 
within finance costs, offsetting the amortization of the interest on the 
underlying borrowings.

If the criteria for hedge accounting are no longer met, or if the 
group revokes the designation, the adjustment to the carrying amount of a 
hedged item for which the effective interest method is used is amortized to 
profit or loss over the period to maturity.

Notes on financial statements1. Significant accounting policies continued
Decommissioning
Liabilities for decommissioning costs are recognized when the group has 
an obligation to dismantle and remove a facility or an item of plant and 
to restore the site on which it is located, and when a reliable estimate of 
that liability can be made. Where an obligation exists for a new facility, 
such as oil and natural gas production or transportation facilities, this 
liability will be recognized on construction or installation. An obligation for 
decommissioning may also crystallize during the period of operation of a 
facility through a change in legislation or through a decision to terminate 
operations. The amount recognized is the present value of the estimated 
future expenditure determined in accordance with local conditions and 
requirements.

A corresponding item of property, plant and equipment of an 
amount equivalent to the provision is also recognized. This is subsequently 
depreciated as part of the asset.

Other than the unwinding discount on the provision, any change 

in the present value of the estimated expenditure is reflected as an 
adjustment to the provision and the corresponding item of property, plant 
and equipment. Such changes include foreign exchange gains and losses 
arising on the retranslation of the liability into the functional currency of the 
reporting entity, when it is known that the liability will be settled in a foreign 
currency.

Environmental expenditures and liabilities
Environmental expenditures that relate to current or future revenues are 
expensed or capitalized as appropriate. Expenditures that relate to an 
existing condition caused by past operations and do not contribute to 
current or future earnings are expensed.

Liabilities for environmental costs are recognized when a clean-up is 
probable and the associated costs can be reliably estimated. Generally, the 
timing of recognition of these provisions coincides with the commitment to 
a formal plan of action or, if earlier, on divestment or on closure of inactive 
sites.

The amount recognized is the best estimate of the expenditure 

required. Where the liability will not be settled for a number of years, 
the amount recognized is the present value of the estimated future 
expenditure.

Employee benefits
Wages, salaries, bonuses, social security contributions, paid annual leave 
and sick leave are accrued in the period in which the associated services 
are rendered by employees of the group. Deferred bonus arrangements 
that have a vesting date more than 12 months after the period end are 
valued on an actuarial basis using the projected unit credit method and 
amortized on a straight-line basis over the service period until the award 
vests. The accounting policies for share-based payments and for pensions 
and other post-retirement benefits are described below.

Share-based payments
Equity-settled transactions
The cost of equity-settled transactions with employees is measured by 
reference to the fair value at the date at which equity instruments are 
granted and is recognized as an expense over the vesting period, which 
ends on the date on which the relevant employees become fully entitled to 
the award. Fair value is determined by using an appropriate valuation model. 
In valuing equity-settled transactions, no account is taken of any vesting 
conditions, other than conditions linked to the price of the shares of the 
company (market conditions). Non-vesting conditions, such as the condition 
that employees contribute to a savings-related plan, are taken into account 
in the grant-date fair value, and failure to meet a non-vesting condition is 
treated as a cancellation, where this is within the control of the employee.

No expense is recognized for awards that do not ultimately vest, 
except for awards where vesting is conditional upon a market condition, 
which are treated as vesting irrespective of whether or not the market 
condition is satisfied, provided that all other performance conditions are 
satisfied.

At each balance sheet date before vesting, the cumulative expense is 
calculated, representing the extent to which the vesting period has expired 
and management’s best estimate of the achievement or otherwise of non-
market conditions and the number of equity instruments that will ultimately 
vest or, in the case of an instrument subject to a market condition, be 
treated as vesting as described above. The movement in cumulative 
expense since the previous balance sheet date is recognized in the income 
statement, with a corresponding entry in equity.

When the terms of an equity-settled award are modified or a new 

award is designated as replacing a cancelled or settled award, the cost 
based on the original award terms continues to be recognized over the 
original vesting period. In addition, an expense is recognized over the 
remainder of the new vesting period for the incremental fair value of any 
modification, based on the difference between the fair value of the original 
award and the fair value of the modified award, both as measured on the 
date of the modification. No reduction is recognized if this difference is 
negative.

When an equity-settled award is cancelled, it is treated as if it had 
vested on the date of cancellation and any cost not yet recognized in the 
income statement for the award is expensed immediately.

Cash-settled transactions
The cost of cash-settled transactions is measured at fair value and 
recognized as an expense over the vesting period, with a corresponding 
liability recognized on the balance sheet.

Pensions and other post-retirement benefits
The cost of providing benefits under the defined benefit plans is 
determined separately for each plan using the projected unit credit method, 
which attributes entitlement to benefits to the current period (to determine 
current service cost) and to the current and prior periods (to determine 
the present value of the defined benefit obligation). Past service costs 
are recognized immediately when the company becomes committed 
to a change in pension plan design. When a settlement (eliminating all 
obligations for benefits already accrued) or a curtailment (reducing future 
obligations as a result of a material reduction in the scheme membership 
or a reduction in future entitlement) occurs, the obligation and related 
plan assets are remeasured using current actuarial assumptions and the 
resultant gain or loss is recognized in the income statement during the 
period in which the settlement or curtailment occurs.

The interest element of the defined benefit cost represents the 

change in present value of scheme obligations resulting from the passage 
of time, and is determined by applying the discount rate to the opening 
present value of the benefit obligation, taking into account material changes 
in the obligation during the year. The expected return on plan assets is 
based on an assessment made at the beginning of the year of long-term 
market returns on plan assets, adjusted for the forecasts of contributions 
received and benefits paid during the year. The difference between the 
expected return on plan assets and the interest cost is recognized in the 
income statement as other finance income or expense.

Actuarial gains and losses are recognized in full within other 

comprehensive income in the year in which they occur.

The defined benefit pension plan surplus or deficit in the balance 

sheet comprises the total for each plan of the present value of the defined 
benefit obligation (using a discount rate based on high quality corporate 
bonds), less the fair value of plan assets out of which the obligations are to 
be settled directly. Fair value is based on market price information and, in 
the case of quoted securities, is the published bid price.

Contributions to defined contribution schemes are recognized in the 

income statement in the period in which they become payable.

Financial statementsNotes on financial statements1. Significant accounting policies continued
Corporate taxes
Income tax expense represents the sum of the tax currently payable and 
deferred tax. Interest and penalties relating to tax are also included in 
income tax expense.

The tax currently payable is based on the taxable profits for the 
period. Taxable profit differs from net profit as reported in the income 
statement because it excludes items of income or expense that are taxable 
or deductible in other periods and it further excludes items that are never 
taxable or deductible. The group’s liability for current tax is calculated using 
tax rates and laws that have been enacted or substantively enacted by the 
balance sheet date.

Deferred tax is provided, using the liability method, on all temporary 
differences at the balance sheet date between the tax bases of assets and 
liabilities and their carrying amounts for financial reporting purposes.

Deferred tax liabilities are recognized for all taxable temporary 

differences except:
•	 Where the deferred tax liability arises on goodwill that is not tax 

deductible or the initial recognition of an asset or liability in a transaction 
that is not a business combination and, at the time of the transaction, 
affects neither accounting profit nor taxable profit or loss.

•	 In respect of taxable temporary differences associated with investments 
in subsidiaries, jointly controlled entities and associates, where the group 
is able to control the timing of the reversal of the temporary differences 
and it is probable that the temporary differences will not reverse in the 
foreseeable future.

Deferred tax assets are recognized for all deductible temporary differences, 
carry-forward of unused tax credits and unused tax losses, to the extent 
that it is probable that taxable profit will be available against which the 
deductible temporary differences and the carry-forward of unused tax 
credits and unused tax losses can be utilized:
•	 Except where the deferred income tax asset relating to the deductible 

temporary difference arises from the initial recognition of an asset or liability 
in a transaction that is not a business combination and, at the time of the 
transaction, affects neither accounting profit nor taxable profit or loss.

•	 In respect of deductible temporary differences associated with 

investments in subsidiaries, jointly controlled entities and associates, 
deferred tax assets are recognized only to the extent that it is probable 
that the temporary differences will reverse in the foreseeable future and 
taxable profit will be available against which the temporary differences 
can be utilized.

The carrying amount of deferred tax assets is reviewed at each balance 
sheet date and reduced to the extent that it is no longer probable that 
sufficient taxable profit will be available to allow all or part of the deferred 
income tax asset to be utilized.

Deferred tax assets and liabilities are measured at the tax rates that 

are expected to apply to the year when the asset is realized or the liability 
is settled, based on tax rates (and tax laws) that have been enacted or 
substantively enacted at the balance sheet date.

Tax relating to items recognized in other comprehensive income 

is recognized in other comprehensive income and tax relating to items 
recognized directly in equity is recognized directly in equity and not in the 
income statement.

Customs duties and sales taxes
Revenues, expenses and assets are recognized net of the amount of 
customs duties or sales tax except:
•	 Where the customs duty or sales tax incurred on a purchase of goods 
and services is not recoverable from the taxation authority, in which 
case the customs duty or sales tax is recognized as part of the cost of 
acquisition of the asset or as part of the expense item as applicable.

•	 Receivables and payables are stated with the amount of customs duty or 

sales tax included.

The net amount of sales tax recoverable from, or payable to, the taxation 
authority is included within receivables or payables in the balance sheet.

Own equity instruments
The group’s holdings in its own equity instruments, including ordinary 
shares held by Employee Share Ownership Plan Trusts (ESOPs), are 
classified as ‘treasury shares’, or ‘own shares’ for the ESOPs, and are 
shown as deductions from shareholders’ equity at cost. Consideration 
received for the sale of such shares is also recognized in equity, with any 
difference between the proceeds from sale and the original cost being 
taken to the profit and loss account reserve. No gain or loss is recognized 
in the income statement on the purchase, sale, issue or cancellation of 
equity shares.

Revenue
Revenue arising from the sale of goods is recognized when the significant 
risks and rewards of ownership have passed to the buyer, which is typically 
at the point that title passes, and the revenue can be reliably measured.

Revenue is measured at the fair value of the consideration received 
or receivable and represents amounts receivable for goods provided in the 
normal course of business, net of discounts, customs duties and sales 
taxes.

Physical exchanges are reported net, as are sales and purchases 
made with a common counterparty, as part of an arrangement similar to 
a physical exchange. Similarly, where the group acts as agent on behalf 
of a third party to procure or market energy commodities, any associated 
fee income is recognized but no purchase or sale is recorded. Additionally, 
where forward sale and purchase contracts for oil, natural gas or power 
have been determined to be for trading purposes, the associated sales 
and purchases are reported net within sales and other operating revenues 
whether or not physical delivery has occurred.

Generally, revenues from the production of oil and natural gas 
properties in which the group has an interest with joint venture partners are 
recognized on the basis of the group’s working interest in those properties 
(the entitlement method). Differences between the production sold and the 
group’s share of production are not significant.

Interest income is recognized as the interest accrues (using the 

effective interest rate that is the rate that exactly discounts estimated 
future cash receipts through the expected life of the financial instrument to 
the net carrying amount of the financial asset).

Dividend income from investments is recognized when the 

shareholders’ right to receive the payment is established.

Research
Research costs are expensed as incurred.

Finance costs
Finance costs directly attributable to the acquisition, construction or 
production of qualifying assets, which are assets that necessarily take a 
substantial period of time to get ready for their intended use, are added 
to the cost of those assets, until such time as the assets are substantially 
ready for their intended use. All other finance costs are recognized in the 
income statement in the period in which they are incurred.

Use of estimates
The preparation of financial statements requires management to make 
estimates and assumptions that affect the reported amounts of assets and 
liabilities as well as the disclosure of contingent assets and liabilities at the 
balance sheet date and the reported amounts of revenues and expenses 
during the reporting period. Actual outcomes could differ from those 
estimates.

Impact of new International Financial Reporting Standards
Adopted for 2011
There are no new or amended standards or interpretations adopted with 
effect from 1 January 2011 that have a significant impact on the financial 
statements.

Notes on financial statements1. Significant accounting policies continued
Not yet adopted
The following pronouncements from the IASB will become effective for 
future financial reporting periods and have not yet been adopted by the group.

• Interests in other entities and related disclosures
In May 2011, the IASB issued three new standards relating to interests 
in other entities and related disclosures. The new standards are IFRS 10 
‘Consolidated Financial Statements’, IFRS 11 ‘Joint Arrangements’ and 
IFRS 12 ‘Disclosure of Interests in Other Entities’. In addition, the IASB 
issued amendments to IAS 27 ‘Consolidated and Separate Financial 
Statements’ (now renamed IAS 27 ‘Separate Financial Statements’) and 
IAS 28 ‘Investments in Associates’ (now renamed IAS 28 ‘Investments in 
Associates and Joint Ventures’).

IFRS 10 introduces a single consolidation model that identifies 

control as the basis for consolidation. The new model applies to all types 
of entities, including structured entities. Under the new model, an investor 
controls an investee when it is exposed, or has rights, to variable returns 
from its involvement with the investee and has the ability to affect those 
returns through its power over the investee.

IFRS 11 establishes a principle that applies to the accounting 

for all joint arrangements, whereby parties to the arrangement account 
for their underlying contractual rights and obligations relating to the 
joint arrangement. IFRS 11 identifies two types of joint arrangements. 
A ‘joint venture’ is defined as a joint arrangement whereby the parties 
that have joint control of the arrangement have rights to the net assets 
of the arrangement. A ‘joint operation’ is defined as a joint arrangement 
whereby the parties that have joint control of the arrangement have 
rights to the assets, and obligations for the liabilities, relating to the 
arrangement. Investments in joint ventures will be accounted for using the 
equity method. Investments in joint operations will be accounted for by 
recognizing the group’s assets, liabilities, revenue and expenses relating to 
the joint operation.

IFRS 12 combines all the disclosure requirements for an entity’s 
interests in subsidiaries, joint arrangements, associates and structured 
entities into one comprehensive disclosure standard.

These new and amended standards are effective for annual periods 

beginning on or after 1 January 2013 and BP intends to adopt them from 
this date. The evaluation of the effect of adoption of these standards has 
not yet been completed. It is expected that the main impact of this suite 
of new standards is that certain of the group’s existing jointly controlled 
entities, which are currently equity accounted, will fall under the definition 
of a joint operation under IFRS 11 and thus we will be required to cease 
equity accounting and instead recognize the group’s assets, liabilities, 
revenue and expenses relating to these arrangements. This new suite of 
standards has not yet been adopted by the EU.

• Other new standards not yet adopted
As part of the IASB’s project to replace IAS 39 ‘Financial Instruments: 
Recognition and Measurement’, in November 2009 the IASB issued the 
first phase of IFRS 9 ‘Financial Instruments’, dealing with the classification 
and measurement of financial assets. In October 2010, the IASB updated 
IFRS 9 by incorporating the requirements for the accounting for financial 
liabilities. The remaining phases of IFRS 9 (covering impairment and hedge 
accounting) are still to be completed. In December 2011, the IASB decided 
that IFRS 9 will be effective for annual periods beginning on or after 1 
January 2015, rather than 1 January 2013 as originally indicated. BP has not 
yet decided the date of adoption for the group and has not yet completed 
its evaluation of the effect of adoption. The new standard has not yet been 
adopted by the EU.

In May 2011, the IASB issued a new standard, IFRS 13 ‘Fair value 
measurement’. The new standard defines fair value, sets out a framework 
for measuring fair value and the required disclosures about fair value 
measurements. IFRS 13 does not require fair value measurements in 

addition to those already required or permitted by other IFRSs, rather it 
prescribes how fair value should be measured if another IFRS requires it. 
Fair value is defined as the price that would be received to sell an asset 
or paid to transfer a liability in an orderly transaction between market 
participants at the measurement date i.e. it is an exit price. IFRS 13 is 
effective for annual periods beginning on or after 1 January 2013 and BP 
intends to adopt it from this date. The evaluation of the effect of adoption of 
IFRS 13 has not yet been completed.

In June 2011, the IASB issued an amended version of IAS 

19 ‘Employee Benefits’, which brings in various changes relating to 
the recognition and measurement of termination benefits and post-
employment defined benefit expense, and to the disclosures for all 
employee benefits. The main impact for BP will be that the expense for 
defined benefit pension and other post-retirement benefit plans will include 
a net interest income or expense, which will be calculated by applying the 
discount rate used for measuring the obligation and applying that to the net 
defined benefit asset or liability. This means that the expected return on 
assets credited to profit or loss (currently calculated based on the expected 
long-term return on pension assets) will now be based on a lower corporate 
bond rate, the same rate that is used to discount the pension liability. The 
amended IAS 19 is effective for annual periods beginning on or after 1 
January 2013 and BP intends to adopt this new standard with effect from 
that date. The evaluation of the effect of adoption of the amended standard 
has not yet been completed, however, based upon our analysis to date, 
we expect the change to result in a significantly higher net charge to the 
income statement once adopted.

In June 2011, the IASB issued amendments to IAS 1 ‘Presentation 

of Financial Statements’ on the presentation of other comprehensive 
income (OCI). The amendments require that those items of OCI that could 
be reclassified to profit or loss at a future date be presented separately 
from those items that will never be reclassified to profit or loss. These 
amendments to IAS 1 are effective for annual periods beginning on or 
after 1 July 2012. BP intends to adopt the amendments with effect from 
1 January 2013. The adoption of the amended standard is expected to only 
have a presentational impact on the group’s financial statements, with no 
effect on the reported income or net assets of the group.

In December 2011, the IASB issued amendments to IFRS 7 

‘Disclosures – Offsetting Financial Assets and Financial Liabilities’ and 
amendments to IAS 32 ‘Offsetting Financial Assets and Financial Liabilities’. 
These amendments introduce new disclosure requirements about the 
effects of offsetting financial assets and financial liabilities and related 
arrangements on an entity’s financial position. The amendments to IFRS 7 
are effective for annual periods beginning on or after 1 January 2013, with 
the amendments to IAS 32 effective for annual periods beginning on or 
after 1 January 2014. BP intends to adopt these amendments with effect 
from 1 January 2013 and 1 January 2014 respectively. The evaluation of the 
effect of adoption of these amendments has not yet been completed.

In October 2010, the IASB issued amendments to IFRS 7 ‘Financial 
Instruments: Disclosures – Transfers of Financial Assets’. The amendments 
address the disclosures of transfers of financial assets. These amendments 
to IFRS 7 are effective for periods beginning on or after 1 July 2011. BP 
intends to adopt the amendments with effect from 1 January 2012. The 
extent to which BP will be required to amend its disclosures in the light of 
these new requirements is currently being evaluated.

With the exception of the amendments to IFRS 7 regarding the 

disclosures of transfers of financial assets, the EU has not yet adopted any 
of the above-mentioned other new standards that have been issued but not 
yet adopted by the group.

There are no other standards and interpretations in issue but not 

yet adopted that the directors anticipate will have a material effect on the 
reported income or net assets of the group.

2. Significant event – Gulf of Mexico oil spill

As a consequence of the Gulf of Mexico oil spill, as described on pages 76 to 79, BP continues to incur costs and has also recognized liabilities for future 
costs. Liabilities of uncertain timing or amount and contingent liabilities have been accounted for and/or disclosed in accordance with IAS 37 ‘Provisions, 
contingent liabilities and contingent assets’. These are discussed in further detail in Note 36 for provisions and Note 43 for contingent liabilities. BP’s rights 
and obligations in relation to the $20-billion trust fund which was established in 2010 are accounted for in accordance with IFRIC 5 ‘Rights to interests 
arising from decommissioning, restoration and environmental rehabilitation funds’. Key aspects of the accounting for the oil spill are summarized below.
The financial impacts of the Gulf of Mexico oil spill on the income statement, balance sheet and cash flow statement of the group are shown in 

the table below. Amounts related to the trust fund are separately identified.

Adjusting event after the reporting period: Settlement with the Plaintiffs’ Steering Committee, subject to final written agreement and court 
approvals, to resolve economic loss and medical claims
Subsequent to BP releasing its preliminary announcement of the fourth quarter 2011 results on 7 February 2012, BP announced on 3 March 2012 that it 
had reached a proposed settlement with the Plaintiffs’ Steering Committee (PSC), subject to final written agreement and court approvals, to resolve the 
substantial majority of legitimate economic loss and medical claims stemming from the Deepwater Horizon accident and oil spill. The PSC acts on behalf 
of individual and business plaintiffs in the Multi-District Litigation proceedings pending in New Orleans (MDL 2179). Under the proposed settlement, class 
members would release and dismiss their claims against BP. The proposed settlement is not an admission of liability by BP. The proposed settlement is 
an adjusting event after the reporting period and therefore has been reflected in the financial statements for 2011 included in this report.

The proposed settlement has not resulted in any increase in the $37.2 billion net pre-tax charge previously recorded in the financial statements. 
BP estimates that the cost of the proposed settlement, which covers Individual and Business Claims and associated costs that are expected to be paid 
from the $20-billion trust fund, would be approximately $7.8 billion. This represents an increase of $2.1 billion in the provision compared to the amount 
reflected in the fourth quarter 2011 preliminary results announcement, with no net impact to either the income statement or cash flow statement, since 
it is expected to be payable from the trust fund – see below for information on accounting for the trust fund. The increase in provision of $2.1 billion has 
been recognized along with a corresponding increase of $2.1 billion in the reimbursement asset. The amount that can further be provided with no net 
impact to the income statement is therefore reduced from approximately $5.5 billion to approximately $3.4 billion. While this is BP’s reliable best estimate 
of the cost of the proposed settlement, it is possible that the actual cost could be higher or lower than this estimate depending on the outcomes of 
the court-supervised claims processes. It is not possible at this time to determine whether the $20-billion trust fund will be sufficient to cover the total 
amounts payable under the proposed settlement and other claims covered by the trust fund.

The proposed settlement is comprised of two separate agreements; one to resolve economic loss claims and another to resolve medical 
claims. Each proposed agreement provides that the class members would be compensated for their claims on a claims-made basis according to agreed 
compensation protocols in separate court-supervised claims processes. The proposed settlement contains a commitment of $2.3 billion in respect of the 
Gulf seafood industry.

2. Significant event – Gulf of Mexico oil spill continued
The proposed economic loss settlement provides for a transition from the Gulf Coast Claims Facility (GCCF). A court-supervised transitional claims 
process for economic loss claims will be in operation while the infrastructure for the new settlement claims process is put in place. During this transitional 
period, the processing of claims that have been submitted to the GCCF will continue, and new claimants may submit their claims.

Costs of the proposed settlement will be paid either from the $20-billion Trust or, should the Trust not be sufficient, directly by BP. At this time BP 

expects all claims to be paid from the Trust.

The proposed settlement does not include claims against BP made by the United States Department of Justice or other federal agencies (including 

under the Clean Water Act and for Natural Resource Damages under the Oil Pollution Act) or by the states and local governments. The proposed 
settlement also excludes certain other claims against BP, such as securities and shareholder claims pending in MDL 2185, and claims based solely on the 
deepwater drilling moratorium and/or the related permitting process.

The proposed settlement also provides that, to the extent permitted by law, BP will assign to the PSC certain of its claims, rights and recoveries 

against Transocean and Halliburton for damages with protections such that Transocean and Halliburton cannot pass those damages through to BP.

The proposed settlement is subject to reaching definitive and fully documented agreements within 45 days of 2 March 2012. If those agreements 

are not reached, either party has the right to terminate the proposed settlement. Once there are definitive and fully documented agreements, BP and 
the PSC would then seek the court’s preliminary approval of the settlement. Under US federal law, there is an established procedure for determining the 
fairness, reasonableness and adequacy of class action settlements. Pursuant to this procedure and subject to the court granting preliminary approval of 
both agreements, there would be an extensive outreach programme to the public to explain the settlement agreements, class members’ rights, including 
the right to ‘opt out’ of the classes, and the process of making claims. The court would then conduct fairness hearings at which class members and 
various other parties would have an opportunity to be heard and present evidence. The court would then decide whether or not to approve each proposed 
settlement agreement.

For further details of the proposed settlement see Legal proceedings on pages 160 to 164.

Trust fund
In 2010, BP established the Deepwater Horizon Oil Spill Trust (the Trust) to be funded in the amount of $20 billion (the trust fund) over the period to 
the fourth quarter of 2013, which is available to satisfy legitimate individual and business claims administered by the Gulf Coast Claims Facility (GCCF), 
state and local government claims resolved by BP, final judgments and settlements, state and local response costs, and natural resource damages and 
related costs. In 2010, BP contributed $5 billion to the fund, and further regular contributions totalling $5 billion were made in 2011. During 2011, BP also 
contributed the cash settlements received from MOEX, Weatherford and Anadarko, amounting in total to $5.1 billion. A further cash settlement from 
Cameron was received in January 2012 and was also contributed to the trust fund. As a result of these accelerated contributions, it is now expected that 
the $20-billion commitment will have been paid in full by the end of 2012. The income statement charge for 2010 included $20 billion in relation to the 
trust fund, adjusted to take account of the time value of money. Fines, penalties and claims administration costs are not covered by the trust fund. The 
establishment of the trust fund does not represent a cap or floor on BP’s liabilities and BP does not admit to a liability of this amount.

Under the terms of the Trust agreement, BP has no right to access the funds once they have been contributed to the trust fund and BP 

has no decision-making role in connection with the payment by the trust fund of individual and business claims resolved by the GCCF and the new 
court-supervised claims processes referred to below. BP will receive funds from the trust fund only upon its expiration, if there are any funds remaining 
at that point. Any amount remaining in the trust fund when the trustees determine that all claims have been settled would be returned to BP. However, 
it is not possible to reliably estimate the number or total amount of the claims that will be settled from the trust fund, and therefore it is not possible to 
reliably measure the fair value of BP’s residual interest in it. The carrying amount of BP’s residual interest is, consequently, nil. BP has the authority under 
the Trust agreement to present certain resolved claims, including natural resource damages claims and state and local response claims, to the Trust for 
payment, by providing the trustees with all the required documents establishing that such claims are valid under the Trust agreement. However, any such 
payments can only be made on the authority of the Trustee and any funds distributed are paid directly to the claimants, not to BP. BP will not settle any 
such items directly or receive reimbursement from the trust fund for such items.

The proposed settlement with the PSC announced on 3 March 2012 provides for a transition from the GCCF. A court-supervised transitional claims 
process for economic loss claims will be in operation while the infrastructure for the new settlement claims process is put in place. During this transitional 
period, the processing of claims that have been submitted to the GCCF will continue, and new claimants may submit their claims. BP has agreed not to 
wait for final approval of the economic loss settlement before claims are paid. The economic loss claims process will continue under court supervision 
before final approval of the settlement, first under the transitional claims process, and then through the settlement claims process established by the 
proposed economic loss settlement.

The Trust will remain in place, unaffected by the proposed settlement and the transition from the GCCF to the new court-supervised claims processes.
BP’s obligation to make contributions to the trust fund was recognized in full in 2010, amounting to $20 billion on an undiscounted basis as it 

is committed to making these contributions. On initial recognition the discounted amount recognized was $19,580 million. After BP’s contributions 
of $15,140 million to the trust fund during 2010 and 2011, and adjustments for discounting, the remaining liability as at 31 December 2011 was 
$4,872 million. This liability is recorded within current other payables on the balance sheet, and is expected to be paid in full before the end of 2012.

An asset has been recognized representing BP’s right to receive reimbursement from the trust fund. This is the portion of the estimated future 
expenditure provided for that will be settled by payments from the trust fund. We use the term ’reimbursement asset‘ to describe this asset. BP will not 
actually receive any reimbursements from the trust fund, instead payments will be made directly to claimants from the trust fund, and BP will be released 
from its corresponding obligation.

2. Significant event – Gulf of Mexico oil spill continued
The portion of the provision recognized during the year for items that will be covered by the trust fund, including the increased estimate of the cost of 
individual and business claims as a result of the proposed settlement with the PSC announced on 3 March 2012, was $4,038 million (2010 $12,567 million) 
and payments of $3,707 million (2010 $3,023 million) were made during the year from the trust fund. The remaining reimbursement asset as at 31 December 
2011 was $9,875 million and is recorded within other receivables on the balance sheet. The amount of the reimbursement asset is equal to the amount of 
provisions as at 31 December 2011 that will be covered by the trust fund – see Note 36 in the table under Provisions relating to the Gulf of Mexico oil spill.

As noted above, the obligation to fund the $20-billion trust fund was recognized in full in 2010, on a discounted basis. In addition, a reimbursement asset 
of $12,567 million was recognized, reflecting the portion of provisions recognized in 2010 that will be covered by the trust fund. Any new provisions, or 
increases in provisions, that are covered by the trust fund (up to the amount of $20 billion) have no net income statement effect as a reimbursement asset 
is also recognized, as described above. During 2011, a further $4,038 million was recognized for new or increased provisions for items covered by the 
trust fund with a corresponding increase in the reimbursement asset, resulting in no net income statement effect. The cumulative charges for provisions, 
and the associated reimbursement asset, recognized during 2010 and 2011 amounted to $16,605 million. Thus, a further $3,395 million could be provided 
in subsequent periods for items covered by the trust fund with no net impact on the income statement. Such future increases in amounts provided could 
arise from adjustments to existing provisions, or from the initial recognition of provisions for items that currently cannot be estimated reliably, namely final 
judgments and settlements and natural resource damages and related costs.

It is not possible at this time to conclude as to whether the $20-billion fund will be sufficient to satisfy all claims under the Oil Pollution Act of 
1990 (OPA 90) that will ultimately be paid. Further information on those items that currently cannot be reliably estimated is provided under Provisions and 
contingencies and in Note 43.

The Trust agreement does not require BP to make further contributions to the trust fund in excess of the agreed $20 billion should this be 

insufficient to cover all claims administered by the GCCF and the new court-supervised claims processes, or to settle other items that are covered by 
the trust fund, as described above. Should the $20-billion trust fund not be sufficient, BP would commence settling legitimate claims and other costs by 
making payments directly to claimants. In this case, increases in estimated future expenditure above $20 billion would be recognized as provisions with a 
corresponding charge in the income statement. The provisions would be utilized and derecognized at the point that BP made the payments.

BP pledged certain Gulf of Mexico assets as collateral for the trust fund funding obligation under an agreement entered into in September 2010. In 

November 2011, the agreement was amended and restated to change the way the overriding royalty interest is determined. For further information see 
Material contracts on page 168. The pledged collateral consists of an overriding royalty interest in oil and gas production of BP’s Thunder Horse, Atlantis, 
Mad Dog, Great White and Mars, Ursa and Na Kika assets in the Gulf of Mexico. A wholly owned company called Verano Collateral Holdings LLC (Verano) 
has been created to hold the overriding royalty interest, which is capped at an amount equal to the product of (i) the outstanding funding obligation as 
calculated at the start of each calendar quarter, from and after 1 October 2011, and (ii) a factor of 1.45 (resulting in an amount of $14.7 billion at 1 October 
2011, which remained unchanged at 31 December 2011). Verano has pledged the overriding royalty interest to the Trust as collateral for BP’s remaining 
contribution obligations to the Trust, amounting to $4.9 billion at the end of 2011. On 2 January 2012 the overriding royalty interest was recalculated as 
$7.1 billion. There has been no change in operatorship or the marketing of the production from the assets and there is no effect on the other partners’ 
interests in the assets. For financial reporting purposes Verano is a consolidated entity of BP and there is no impact on the consolidated financial 
statements from the pledge of the overriding royalty interest.

Provisions and contingencies
At 31 December 2011 BP has recorded certain provisions and disclosed certain contingent liabilities as a consequence of the Gulf of Mexico oil spill. 
These are described below under Oil Pollution Act of 1990 and Other items.

Oil Pollution Act of 1990 (OPA 90)
The claims against BP under the OPA 90 and for personal injury fall into three categories: (i) claims by individuals and businesses for removal costs, 
damage to real or personal property, lost profits or impairment of earning capacity, loss of subsistence use of natural resources and for personal injury 
(“Individual and Business Claims”); (ii) claims by state and local government entities for removal costs, physical damage to real or personal property, loss 
of government revenue and increased public services costs (“State and Local Claims”); and (iii) claims by the United States, a State trustee, an Indian tribe 
trustee, or a foreign trustee for natural resource damages (“Natural Resource Damages claims”). In addition, BP faces civil litigation in which claims for 
liability under OPA 90 along with other causes of actions, including personal injury claims, are asserted by individuals, businesses and government entities.

A provision has been recorded for Individual and Business Claims and State and Local Claims. The proposed settlement with the PSC, subject to 
final written agreement and court approvals, announced on 3 March 2012 relates to Individual and Business Claims. A provision has also been recorded 
for claims administration costs, natural resource damage assessment costs and costs relating to emergency and early natural resource damages 
restoration agreements.

2. Significant event – Gulf of Mexico oil spill continued
BP considers that it is not possible to measure reliably any other obligation in relation to Natural Resource Damages claims under OPA 90 or litigation for 
violations of OPA 90 (other than as included within the proposed settlement). These items are therefore disclosed as contingent liabilities.

The $20-billion trust fund described above is available to satisfy the OPA 90 claims and litigation referred to above, however claims administration 

costs associated with the existing GCCF organization are borne separately by BP. The administration costs of processing claims made under the proposed 
settlement agreement with the PSC are expected to be paid from the trust fund. However, at this time, the provision for these costs is shown as payable 
from outside the trust fund as the proposed settlement agreement is subject to final written agreement and court approvals. BP’s rights and obligations 
in relation to the trust fund have been recognized and $20 billion, adjusted to take account of the time value of money, was charged to the income 
statement in 2010.

Other items
Provisions at 31 December 2011 also include amounts in relation to completing the oil spill response, BP’s commitment to a 10-year research programme 
in the Gulf of Mexico, estimated penalties for liability under Clean Water Act Section 311 and estimated legal fees. These are not covered by the trust fund.
The provision does not reflect any amounts in relation to fines and penalties except for those relating to the Clean Water Act, as it is not possible 

to estimate reliably either the amount or timing of such additional items. BP also considers that it is not possible to measure reliably any obligation in 
relation to litigation other than as included within the proposed settlement with the PSC. These items are therefore disclosed as contingent liabilities.
Further information on provisions is provided below and in Note 36. Further information on contingent liabilities is provided in Note 43.
A provision has been recognized for estimated future expenditure relating to the incident, for items that can be measured reliably at this time, 

including the increased estimate of the cost of Individual and Business Claims as a result of the proposed settlement with the PSC as described above, in 
accordance with BP’s accounting policy for provisions, as set out in Note 1.

The total amount recognized as a provision during the year was $5,183 million, including $4,038 million for items covered by the trust fund and 
$1,145 million for other items (2010 $30,261 million, including $12,567 million for items covered by the trust fund and $17,694 million for other items). 
After deducting amounts utilized during the year totalling $6,208 million, including payments from the trust fund of $3,707 million and payments made 
directly by BP of $2,501 million (2010 $13,935 million, including payments from the trust fund of $3,023 million and payments made directly by BP of 
$10,912 million), and after adjustments for discounting, the remaining provision as at 31 December 2011 was $15,333 million (2010 $16,335 million).

Movements in the provision are presented in the table below.

The total amounts that will ultimately be paid by BP in relation to all obligations relating to the incident are subject to significant uncertainty and the ultimate 
exposure and cost to BP will be dependent on many factors (including, with respect to certain of the obligations, any determination of BP’s culpability based 
on any findings of negligence, gross negligence or wilful misconduct). Significant uncertainty exists in relation to the amount of claims that will become 
payable by BP, the amount of fines that will ultimately be levied on BP, the outcome of litigation and arbitration proceedings, the amount and timing of 
payments under any settlements, and any costs arising from any longer-term environmental consequences of the oil spill, which will also impact upon 
the ultimate cost for BP. BP is ready to settle any remaining matters on fair and reasonable terms, but will continue to prepare vigorously for trial. Any 
settlements which may be reached relating to the Deepwater Horizon oil spill could impact the amount and timing of any future payments. Although the 
provision recognized is the current best reliable estimate of expenditures required to settle certain present obligations at the end of the reporting period, 
there are future expenditures for which it is not possible to measure the obligation reliably as noted above.

Impact upon the group income statement
The group income statement for 2011 includes a pre-tax credit of $3,742 million (2010 pre-tax charge of $40,935 million) in relation to the Gulf of Mexico 
oil spill. The amount charged to date comprises costs incurred up to 31 December 2011, settlements agreed with our co-owners of the Macondo well 
and other third parties, estimated obligations for future costs that can be estimated reliably at this time and rights and obligations relating to the trust fund. 
Finance costs of $58 million (2010 $77 million) reflect the unwinding of the discount on the trust fund liability and provisions.
The amount of the provision recognized during the year can be reconciled to the income statement amount as follows:

Increase in provision
Change in discount rate relating to provisions
Costs charged directly to the income statement
Trust fund liability – discounted
Change in discounting relating to trust fund liability
Recognition of reimbursement asset

The total amounts that will ultimately be paid by BP in relation to all obligations relating to the incident are subject to significant uncertainty as described 
above under Provisions and contingencies.

  Pre-tax cash flows amounted to $8,906 million (2010 $17,658 million) and the impact on net cash provided by operating activities, on a post-tax 

basis, amounted to $6,813 million (2010 $16,019 million).

3. Business combinations

Business combinations in 2011
BP undertook a number of business combinations in 2011. Total consideration paid in cash amounted to $11.3 billion, offset by cash acquired of 
$0.4 billion. In addition, the fair value of contingent consideration payable amounted to $0.1 billion.

On 30 August 2011, BP acquired from Reliance Industries Limited (Reliance) a 30% interest in 21 oil and gas production-sharing agreements 

(PSAs) operated by Reliance in India for $7,026 million. This includes the producing KG D6 block.

In addition, on 17 November 2011, the companies formed a 50:50 joint venture for the sourcing and marketing of gas in India.
This transaction provides BP with access to an emerging market with growth in energy demand; it builds BP’s business in natural gas and it 

represents an important partnership with a leading national energy business.

The transaction has been accounted for as a business combination using the acquisition method. Measurement period adjustments to the 
acquisition-date fair values of the identifiable assets and liabilities acquired, and contingent consideration payable, were recognized between the date of 
acquisition and 31 December 2011. These adjustments reflected new information obtained, including further understanding of the acquired assets and 
potential development options, and amounted to an overall decrease of $785 million in the net fair value of the identifiable assets and liabilities acquired, 
an increase of $854 million in the goodwill arising on acquisition and the recognition of $69 million of contingent consideration.

Goodwill of $2,523 million arose on acquisition, attributed to market access and other benefits arising from the business combination. It is 

currently uncertain as to whether goodwill recognized for accounting purposes will be deductible for income tax purposes in India, as jurisprudence in 
this area is currently evolving.

The provisional fair values of the identifiable assets and liabilities acquired, as at the date of acquisition, are as shown in the table below.

The consideration for the transaction included $6,957 million in cash. In addition, contingent consideration of up to $1,800 million, dependent upon 
exploration success in certain of the interests resulting in the development of commercial discoveries, was agreed. The fair value of contingent 
consideration recognized as at the acquisition date amounted to $69 million.

3. Business combinations continued
The acquisition-date fair values of the assets and liabilities acquired and the fair value of contingent consideration to be paid are provisional. As we gain 
further understanding of the acquired properties and development options, these fair values may be further adjusted to reflect information which may be 
obtained in respect of the acquired assets and liabilities.  

An analysis of the cash flows relating to the acquisition is provided below.

Transaction costs of the acquisition (included in cash flows from operating activities)
Cash consideration paid (included in cash flows from investing activities)
Total net cash outflow for the acquisition

$ million
13
6,957
6,970

Transaction costs of $13 million have been charged within production and manufacturing expenses in the group income statement.

From the date of acquisition to 31 December 2011, the acquired activities contributed revenues of $268 million and profit of $49 million to the 
group. If the business combination had taken place on 1 January 2011, it is estimated that the acquired activities would have contributed revenues of 
$884 million and profit of $219 million to the group.

In addition to the Reliance transaction described above, BP undertook a number of other business combinations in 2011. These included the 
completion of the final part of the transaction with Devon Energy (Devon), the acquisition of Devon’s equity stake in a number of assets in Brazil for 
consideration of $3.6 billion (see below). Additionally, BP’s Alternative Energy business acquired Companhia Nacional de Açúcar e Álcool (CNAA) in Brazil 
for consideration of $0.7 billion and increased its share in the Brazilian biofuels company, Tropical BioEnergia S.A., to 100% by acquiring the remaining 
50% for consideration of $71 million. There were a number of other individually insignificant business combinations.

Business combinations in 2010
BP undertook a number of business combinations in 2010 for a total consideration of $3.6 billion, of which $3 billion comprised cash consideration. The 
most significant acquisition was a transaction in the Exploration and Production segment with Devon, undertaken in a number of stages during 2010 and 
2011. This transaction strengthens BP’s position in the Gulf of Mexico, enhances interests in Azerbaijan and facilitates the development of Canadian assets.
On 27 April 2010, BP acquired 100% of Devon’s Gulf of Mexico deepwater properties for $1.8 billion. This included a number of exploration 
properties, Devon’s interest in the major Paleogene discovery Kaskida (giving BP a 100% interest in the project), four producing assets and one non-
producing asset. As part of the transaction, BP sold to Devon a 50% stake in its Kirby oil sands interests in Alberta, Canada for $500 million and Devon 
committed to fund an additional $150 million of capital costs on BP’s behalf by issuing a promissory note to BP. In addition, the companies formed a 50:50 
joint venture, operated by Devon, to pursue the development of the interest. On 16 August 2010, the group acquired Devon’s 3.29% (after pre-emption 
exercised by some of the partners) interest in the BP-operated Azeri-Chirag-Gunashli (ACG) development in the Azerbaijan sector of the Caspian Sea for 
$1.1 billion, increasing BP’s interest to 37.43%.

The business combination was accounted for using the acquisition method. Goodwill of $332 million was recognized on the 2010 part of the 

Devon transaction. As part of the Devon transaction, the gain on the disposal of the group’s 50% interest in the Kirby oil sands in Alberta, Canada 
amounted to $633 million.

The final part of the Devon transaction, the acquisition of 100% of Devon’s equity stake in a number of entities holding all of Devon’s assets in 

Brazil for consideration of $3.6 billion, completed in May 2011. The acquisition-date fair values are provisional. Goodwill of $966 million was recognized in 
2011 for this part of the transaction.

In addition to the Devon transaction, BP undertook a number of other minor business combinations in 2010, the most significant of which was the 

acquisition by BP’s Alternative Energy business of Verenium Corporation’s lignocellulosic biofuels business, for consideration of $98 million.

Business combinations in 2009
BP did not undertake any significant business combinations in 2009.

Financial statementsNotes on financial statements4. Non-current assets held for sale

As a result of the group’s disposal programme following the Gulf of Mexico oil spill, various assets, and associated liabilities, have been presented as 
held for sale in the group balance sheet at 31 December 2011. The carrying amount of the assets held for sale is $8,420 million, with associated liabilities 
of $538 million. Included within these amounts are the following items, all of which relate to the Exploration and Production segment, unless otherwise 
stated.

On 18 October 2010, BP announced that it had reached agreement to sell its upstream and midstream assets in Vietnam, together with its 
upstream businesses and associated interests in Venezuela, to TNK-BP for $1.8 billion in cash, subject to post-closing adjustments. The sale of the 
Venezuelan business and the upstream and certain midstream assets in Vietnam completed during 2011. BP is in ongoing negotiations and expects to 
complete a sale of its equity-accounted investment in the Phu My 3 plant facility in 2012, subject to the satisfaction of regulatory and other approvals and 
conditions. The investment in the Phu My 3 plant facility has been classified as held for sale in the group balance sheet at 31 December 2011.

On 1 December 2011, BP announced that it had agreed to sell its Canadian natural gas liquids (NGL) business to Plains Midstream Canada ULC 
(Plains Midstream), a wholly-owned subsidiary of Plains All American Pipeline, L.P. Plains Midstream will pay BP a total of $1.67 billion in cash, subject 
to post-closing adjustments, for the business. The assets, and associated liabilities, of this business have been classified as held for sale in the group 
balance sheet at 31 December 2011. Completion of the transaction is subject to closing conditions including the receipt of all necessary governmental and 
regulatory approvals. The sale is expected to be completed in the first half of 2012.

Within the Refining and Marketing segment, BP intends to divest the Texas City refinery and related assets, and the southern part of its US West 
Coast fuels value chain, including the Carson refinery. The non-current assets, together with the inventories, of these businesses have been classified as 
held for sale in the group balance sheet at 31 December 2011. BP intends to complete the sales in 2012.

Impairment losses amounting to $398 million (2010 $192 million) have been recognized in relation to certain assets classified as held for sale. 

See Note 5 for further information.

Non-current assets classified as held for sale are not depreciated. It is estimated that the benefit arising from the absence of depreciation for the 

assets noted above amounted to approximately $166 million (2010 $162 million).

Deposits of $30 million ($6,197 million at 31 December 2010) received in advance of completion of certain of these transactions have been 
classified as finance debt on the group balance sheet at 31 December 2011 and of this, none (2010 $4,780 million) has been secured on the assets held 
for sale.

The majority of the transactions noted above are subject to post-closing adjustments, which may include adjustments for working capital and 

adjustments for profits attributable to the purchaser between the agreed effective date and the closing date of the transaction. Such post-closing 
adjustments may result in the final amounts received by BP from the purchasers differing from the disposal proceeds noted above.

The major classes of assets and liabilities reclassified as held for sale as at 31 December are as follows:

Assets

Property, plant and equipment
Goodwill
Intangible assets
Investments in jointly controlled entities
Investments in associates
Loans
Inventories
Cash
Other current assets

Assets classified as held for sale
Liabilities

 a On 28 November 2010, BP announced that it had reached agreement to sell its interests in Pan American Energy LLC (PAE) to Bridas Corporation (Bridas) for $7.06 billion in cash. PAE is an Argentina-based 
oil and gas company owned by BP (60%) and Bridas (40%). On 5 November 2011, BP received from Bridas a notice of termination of the agreement. As a result of Bridas’s decision and action, the share 
purchase agreement governing this transaction was terminated. BP’s interest in PAE was classified as held for sale in the group balance sheet from the date the sale was originally agreed in 2010, and 
equity accounting for PAE was discontinued from that date. Following the termination of the sale agreement, BP’s interest in PAE no longer meets the criteria to be classified as held for sale. Under 
IFRS, equity accounting is reinstated and prior periods are adjusted when a jointly controlled entity ceases to be classified as held for sale. Consequently, BP’s investment in PAE at 31 December 2010 of 
$2,641 million has been reclassified in the group balance sheet from assets classified as held for sale to investments in jointly controlled entities. BP’s share of PAE’s profit for 2011 has been recognized 
in full in the group income statement; the 2010 income statement has not been adjusted as the amount is insignificant. Comparative financial information for 2010 presented in the table above has been 
adjusted to exclude PAE. For further information on the termination of this agreement see page 85.

There were no accumulated foreign exchange gains or losses recognized directly in equity relating to the assets held for sale at 31 December 2011 (2010 nil).

Included in proceeds from disposal for 2010 are deposits of $6,197 million received from counterparties in respect of disposal transactions in the 
Exploration and Production segment not completed at 31 December 2010, of which $30 million related to transactions still not completed at 31 December 
2011. This included a deposit of $3,530 million received in advance of the expected sale of our interest in Pan American Energy LLC. 2011 proceeds from 
disposal included the repayment of the same amount following the termination of the sale agreement as described in Note 4. No disposal deposits were 
received in 2011 or 2009 for expected transactions which had not completed by the end of those years. For further information on disposal transactions 
not yet completed see Note 4.

Deferred consideration relating to disposals of businesses and fixed assets at 31 December 2011 amounted to $117 million receivable within one 

year (2010 $562 million and 2009 $807 million) and $111 million receivable after one year (2010 $271 million and 2009 $691 million).

Disposals
As part of the response to the consequences of the Gulf of Mexico oil spill, the group announced plans to deliver up to $30 billion of disposal proceeds by 
the end of 2011. This target has now been increased to $38 billion of disposal proceeds by the end of 2013. Prior to this, in the normal course of business, 
the group has sold interests in exploration and production properties, service stations and pipeline interests as well as non-core businesses. The group has 
also disposed of other assets in the past, such as refineries, when this has met strategic objectives.

See Note 4 for further information relating to assets and associated liabilities held for sale at 31 December 2011.

Exploration and Production
In 2011, the major disposal transactions were the sale of our interests in Colombia to Ecopetrol and Talisman, the sale of our upstream and midstream 
assets in Vietnam and our investments in equity-accounted entities in Venezuela to TNK-BP, and the sale of our assets in Pakistan to United Energy 
Group. In addition, we also completed the disposal of half of the 3.29% interest in the Azeri-Chirag-Gunashli development in Azerbaijan to SOCAR and a 
number of interests in the Gulf of Mexico to Marubeni Group. All of these transactions resulted in gains.

In 2010, the major transactions were the sale of Permian Basin assets in the US, upstream gas assets in Canada and exploration concessions in 
Egypt to Apache Corporation. In addition, we sold 50% of our interests in Kirby oil sands in Canada to Devon Energy as part of a business combination 
described in Note 3. All of these transactions resulted in gains.

In 2009, the major transactions were the sale of BP West Java Limited in Indonesia, the sale of our 49.9% interest in Kazakhstan Pipeline  
Ventures LLC and the sale of our 46% stake in LukArco, all of which resulted in gains. We also exchanged interests in a number of fields in the North Sea 
with BG Group plc.

Refining and Marketing
In 2011, gains on disposal resulted from our disposal of the fuels marketing business in Namibia, Malawi, Zambia and Tanzania to Puma Energy, certain 
non-strategic pipelines and terminals in the US and other assets in the segment. Losses resulted from the disposal of a number of assets in the segment 
portfolio.

In 2010, gains resulted from our disposals of the French retail fuels and convenience business to Delek Europe, the fuels marketing business in 
Botswana to Puma Energy, certain non-strategic pipelines and terminals in the US, our interests in ethylene and polyethylene production in Malaysia to 
Petronas and our interest in a futures exchange. Losses resulted from the disposal of a number of assets in the segment portfolio.

In 2009, gains on disposal mainly resulted from the disposal of our ground fuels marketing business in Greece and retail churn in the US, Europe 
and Australasia. Losses resulted from the disposal of company-owned and company-operated retail sites in the US, retail churn and disposals of assets 
elsewhere in the segment portfolio. Retail churn is the overall process of acquiring and disposing of retail sites by which the group aims to improve the 
quality and mix of its portfolio of service stations.

Other businesses and corporate
In 2011, we disposed of our aluminium business in the US which resulted in a gain. We also contributed Mehoopany and Flat Ridge 2 wind energy 
development assets in exchange for cash and 50% equity interests in the jointly controlled entities Mehoopany Wind Holdings LLC and Flat Ridge 2 Wind 
Holdings LLC.

In 2010, we disposed of our 35% interest in K-Power, a gas-fired power asset in South Korea, and contributed our Cedar Creek 2 wind energy 

development asset in exchange for a 50% equity interest in a jointly controlled entity, Cedar Creek II Holdings LLC (Cedar Creek 2) and cash. In addition, 
there was a return of capital in the jointly controlled entities Fowler II Holdings LLC and Cedar Creek II Holdings LLC which did not change our percentage 
interest in either entity.

During 2009, we disposed of our wind energy business in India and contributed our Fowler 2 wind energy development asset in the US in 
exchange for a 50% equity interest in a jointly controlled entity, Fowler II Holdings LLC. In addition, there was a return of capital in the jointly controlled 
entity Fowler Ridge Wind Farm LLC which did not change our percentage interest in the entity.

 d Net of cash and cash equivalents disposed of $14 million (2010 $55 million and 2009 $91 million).

Impairment
In assessing whether a write-down is required in the carrying value of a potentially impaired intangible asset, item of property, plant and equipment or an 
equity-accounted investment, the asset’s carrying value is compared with its recoverable amount. The recoverable amount is the higher of the asset’s fair 
value less costs to sell and value in use. Unless indicated otherwise, the recoverable amount used in assessing the impairment losses described below 
is value in use. The group estimates value in use using a discounted cash flow model. The future cash flows are adjusted for risks specific to the asset 
and are discounted using a pre-tax discount rate. This discount rate is derived from the group’s post-tax weighted average cost of capital and is adjusted 
where applicable to take into account any specific risks relating to the country where the cash-generating unit is located, although other rates may be used 
if appropriate to the specific circumstances. In 2011 the rates used ranged from 12-14% (2010 11-14%). The rate applied in each country is reassessed 
each year. In certain circumstances an impairment assessment may be carried out using fair value less costs to sell as the recoverable amount when, for 
example, a recent market transaction for a similar asset has taken place. For impairments of available-for-sale financial assets that are quoted investments, 
the fair value is determined by reference to bid prices at the close of business at the balance sheet date. Any cumulative loss previously recognized in 
other comprehensive income is transferred to the income statement.

198    BP Annual Report and Form 20-F 2011

Notes on financial statements5. Disposals and impairment continued

Exploration and Production
During 2011, the Exploration and Production segment recognized impairment losses of $1,443 million. The main elements were a $555-million 
impairment loss relating to a number of our interests in the Gulf of Mexico, caused by an increase in the decommissioning provision as a result of further 
assessments of the regulations relating to idle infrastructure and a decrease in our assumption of the discount rate for provisions; the $393-million  
write-down of our interest in the Fayetteville shale gas asset in the US, triggered by a decrease in value by reference to a sale transaction by a partner of 
its interest in the same asset; and the $153-million write-down of our interest in the proposed Denali gas pipeline in Alaska, resulting from a decision not 
to proceed with the project. There were several other impairment losses amounting to $342 million in total that were not individually significant. These 
impairment losses were partly offset by reversals of impairment of certain of our interests in the Gulf of Mexico and Egypt amounting to $146 million in 
total, triggered by an increase in our assumption of long-term oil prices.

During 2010, the Exploration and Production segment recognized impairment losses of $1,259 million. The main elements were the $501-million 

write-down of assets in the Gulf of Mexico, triggered by an increase in the decommissioning provision as a result of new regulations in the US relating 
to idle infrastructure; impairments of oil and gas properties in the Gulf of Mexico and onshore North America of $310 million and $80 million respectively, 
as a result of decisions to dispose of assets at a price lower than the assets’ carrying values; a $341-million write-down of accumulated costs in Sakhalin, 
Russia, triggered by a change in the outlook on the future recoverability of the investment; and several other individually insignificant impairment losses 
amounting to $27 million in total.

During 2009, the Exploration and Production segment recognized impairment losses of $118 million. The main elements were the write-down of 

our $42-million investment in the East Shmidt interest in Russia, triggered by a decision to not proceed to development; a $62-million charge associated 
with our nErgize gas scheduling system; and several other individually insignificant impairment losses amounting to $14 million.

Refining and Marketing
During 2011, the Refining and Marketing segment recognized impairment losses of $599 million. Impairment losses of $398 million related to assets 
classified as held for sale. Other impairment losses were also recognized relating to retail churn in Europe and other minor asset disposals amounting to 
$201 million in total.

During 2010, the Refining and Marketing segment recognized impairment losses amounting to $144 million relating to retail churn in Europe and 

other minor asset disposals. These losses were largely offset by the reversal of a previously recognized impairment loss of $141 million relating to the 
investment in our jointly controlled entity China American Petrochemical Company resulting from a change in market conditions.

During 2009, an impairment loss of $1,579 million was recognized against the goodwill allocated to the US West Coast fuels value chain (FVC). The 
goodwill was originally recognized at the time of the ARCO acquisition in 2000. The prevailing weak refining environment, together with a review of future 
margin expectations in the FVC, led to a reduction in the expected future cash flows. Other impairment losses were also recognized by the segment on a 
number of assets which amounted to $255 million.

Other businesses and corporate
During 2011, 2010 and 2009, Other businesses and corporate recognized impairment losses totalling $58 million, $113 million and $189 million 
respectively related to various assets in the Alternative Energy business.

Financial statementsNotes on financial statements6. Segmental analysis

The group’s organizational structure reflects the various activities in which BP is engaged. In 2011, BP had two reportable segments: Exploration and 
Production and Refining and Marketing. BP’s activities in low-carbon energy are managed through our Alternative Energy business, which is reported in 
Other businesses and corporate. The group is managed on an integrated basis.

Exploration and Production’s activities include oil and natural gas exploration, field development and production; midstream transportation, storage 

and processing; and the marketing and trading of natural gas, including liquefied natural gas (LNG), together with power and natural gas liquids (NGLs).
At the end of 2010, BP announced its decision to reorganize its Exploration and Production segment to create three functional divisions – 
Exploration, Developments and Production, integrated through a Strategy and Integration organization. This structure was established in March 2011 but 
this has not affected the group’s reportable segments and Exploration and Production continues to be reported as a single operating segment. 

From 1 January 2012, the group’s investment in TNK-BP will be reported as a separate operating segment, rather than within the Exploration and 

Production segment, reflecting the way in which the investment is now managed.

Refining and Marketing’s activities include the refining, manufacturing, marketing, transportation, and supply and trading of crude oil, petroleum, 

petrochemicals products and related services to wholesale and retail customers.

Other businesses and corporate comprises the Alternative Energy business, Shipping, Treasury (which in the segmental analysis includes all of 
the group’s cash, cash equivalents and associated interest income), and corporate activities worldwide. It also included the group’s aluminium business 
until its disposal during 2011. The Alternative Energy business is an operating segment that has been aggregated with the other activities within Other 
businesses and corporate as it does not meet the materiality thresholds for separate segment reporting.

In 2010, following the Gulf of Mexico incident, we established the Gulf Coast Restoration Organization (GCRO) and equipped it with dedicated 

resources and capabilities to manage all aspects of our response to the incident. This organization reports directly to the group chief executive and is 
overseen by a board committee, however it is not an operating segment.

The accounting policies of the operating segments are the same as the group’s accounting policies described in Note 1. However, IFRS requires 

that the measure of profit or loss disclosed for each operating segment is the measure that is provided regularly to the chief operating decision maker for 
the purposes of performance assessment and resource allocation. For BP, this measure of profit or loss is replacement cost profit or loss before interest 
and tax which reflects the replacement cost of supplies by excluding from profit or loss inventory holding gains and lossesa. Replacement cost profit or 
loss for the group is not a recognized GAAP measure.

Sales between segments are made at prices that approximate market prices, taking into account the volumes involved. Segment revenues 
and segment results include transactions between business segments. These transactions and any unrealized profits and losses are eliminated on 
consolidation, unless unrealized losses provide evidence of an impairment of the asset transferred. Sales to external customers by region are based on 
the location of the seller. The UK region includes the UK-based international activities of Refining and Marketing.

All surpluses and deficits recognized on the group balance sheet in respect of pension and other post-retirement benefit plans are allocated to 
Other businesses and corporate. However, the periodic expense relating to these plans is allocated to the other operating segments based upon the 
business in which the employees work.

Certain financial information is provided separately for the US as this is an individually material country for BP, and for the UK as this is BP’s 

country of domicile.

 a Inventory holding gains and losses represent the difference between the cost of sales calculated using the average cost to BP of supplies acquired during the period and the cost of sales calculated 
on the first-in first-out (FIFO) method after adjusting for any changes in provisions where the net realizable value of the inventory is lower than its cost. Under the FIFO method, which we use for IFRS 
reporting, the cost of inventory charged to the income statement is based on its historic cost of purchase, or manufacture, rather than its replacement cost. In volatile energy markets, this can have 
a significant distorting effect on reported income. The amounts disclosed represent the difference between the charge (to the income statement) for inventory on a FIFO basis (after adjusting for any 
related movements in net realizable value provisions) and the charge that would have arisen if an average cost of supplies was used for the period. For this purpose, the average cost of supplies during 
the period is principally calculated on a monthly basis by dividing the total cost of inventory acquired in the period by the number of barrels acquired. The amounts disclosed are not separately reflected in 
the financial statements as a gain or loss. No adjustment is made in respect of the cost of inventories held as part of a trading position and certain other temporary inventory positions.

Goodwill acquired through business combinations has been allocated to groups of cash-generating units that are expected to benefit from the synergies 
of the acquisition. For Exploration and Production, goodwill is held at the segment level; previously it was allocated to each geographic region (UK, US and 
Rest of World) (see below). For Refining and Marketing, goodwill has been allocated to the Rhine fuels value chain (FVC), Lubricants and Other.

In assessing whether goodwill has been impaired, the carrying amount of the cash-generating unit (including goodwill) is compared with the 
recoverable amount of the cash-generating unit. The recoverable amount is the higher of fair value less costs to sell and value in use. In the absence of any 
information about the fair value of a cash-generating unit, the recoverable amount is deemed to be the value in use.

The group calculates the value in use using a discounted cash flow model. The future cash flows are adjusted for risks specific to the  

cash-generating unit and are discounted using a pre-tax discount rate. The discount rate is derived from the group’s post-tax weighted average cost of 
capital and is adjusted where applicable to take into account any specific risks relating to the country where the cash-generating unit is located. The rate 
to be applied to each country is reassessed each year. Discount rates of 12% and 14% have been used for goodwill impairment calculations performed in 
2011 (2010 12% and 14%).

The business segment plans, which are approved on an annual basis by senior management, are the primary source of information for the 
determination of value in use. They contain forecasts for oil and natural gas production, refinery throughputs, sales volumes for various types of refined 
products (e.g. gasoline and lubricants), revenues, costs and capital expenditure. As an initial step in the preparation of these plans, various environmental 
assumptions, such as oil prices, natural gas prices, refining margins, refined product margins and cost inflation rates, are set by senior management. 
These environmental assumptions take account of existing prices, global supply-demand equilibrium for oil and natural gas, other macroeconomic factors 
and historical trends and variability.

The value in use is based on the cash flows expected to be generated by the projected oil or natural gas production profiles up to the expected dates 
of cessation of production of each producing field. As the production profile and related cash flows can be estimated from BP’s past experience, 
management believes that the cash flows generated over the estimated life of field is the appropriate basis upon which to assess goodwill and individual 
assets for impairment. The date of cessation of production depends on the interaction of a number of variables, such as the recoverable quantities of 
hydrocarbons, the production profile of the hydrocarbons, the cost of the development of the infrastructure necessary to recover the hydrocarbons, 
the production costs, the contractual duration of the production concession and the selling price of the hydrocarbons produced. As each producing field 
has specific reservoir characteristics and economic circumstances, the cash flows of the fields are computed using appropriate individual economic 
models and key assumptions agreed by BP’s management for the purpose. Capital expenditure and operating costs for the first four years and expected 
hydrocarbon production profiles up to 2020 are derived from the business segment plan. Estimated production quantities and cash flows up to the date 
of cessation of production on a field-by-field basis are developed to be consistent with this. The production profiles used are consistent with the resource 
volumes approved as part of BP’s centrally-controlled process for the estimation of proved reserves and total resources.

Prior to 2011, goodwill in the Exploration and Production segment was allocated to each geographic region, that is UK, US and Rest of World, and 

impairment reviews of goodwill were performed at this level. Following a reorganization of the Exploration and Production segment, the group has revised 
the way goodwill is monitored for internal management purposes. Given the global nature of our upstream business, the impairment review of goodwill is 
now performed at the Exploration and Production segment level. Consistent with prior years, the 2011 review for impairment was carried out during the 
fourth quarter.

The table above shows the carrying amount of the goodwill for the segment and the excess of the recoverable amount over the carrying amount 

(the headroom). Consistent with prior periods, midstream and intangible oil and gas assets were excluded from the headroom calculation.

The Brent oil price assumption used in the impairment review of goodwill is shown in the table below.

Key assumptions for oil and gas prices for the first five years were derived from forward price curves in the fourth quarter. Prices in 2017 and beyond 
were determined using long-term views of global supply and demand, building upon past experience of the industry and consistent with external sources. 
These prices were adjusted to arrive at appropriate consistent price assumptions for different qualities of oil and gas, or where appropriate, contracted oil 
and gas prices were applied.

206    BP Annual Report and Form 20-F 2011

Notes on financial statements10. Impairment review of goodwill continued
The key assumptions required for the value-in-use estimation are the oil and natural gas prices, production volumes and the discount rate. To test the 
sensitivity of the headroom to changes in production volumes and oil and natural gas prices, management has developed ‘rules of thumb’ for key 
assumptions. Applying these gives an indication of the impact on the headroom of possible changes in the key assumptions. Due to the non-linear 
relationship of different variables, the calculations were performed using a number of simplified assumptions, therefore a detailed calculation at any given 
price may produce a different result.

It was estimated that if the oil price assumption was around 25% lower than the current assumption for 2017 and beyond, this would cause the 
recoverable amount to be equal to the carrying amount of goodwill and related non-current assets of the segment. It was estimated that no reasonably 
possible change in the long-term price of natural gas would cause the headroom to be reduced to zero.

Estimated production volumes are based on detailed data for the fields and take into account development plans for the fields agreed by 
management as part of the long-term planning process. In 2011, it was estimated that, if all our production were to be reduced by 10% for the whole of 
the next 15 years, this would not be sufficient to reduce the excess of recoverable amount over the carrying amount to zero. Consequently, management 
believes no reasonably possible change in the production assumption would cause the carrying amount to exceed the recoverable amount.

Management also believes that currently there is no reasonably possible change in discount rate that would cause the carrying amount to exceed 

the recoverable amount.

Cash flows for each cash-generating unit are derived from the business segment plans, which cover a period of two to five years. To determine the value 
in use for each of the cash-generating units, cash flows for a period of 10 years are discounted and aggregated with a terminal value.

Rhine FVC
The key assumptions to which the calculation of value in use for the Rhine FVC is most sensitive are refinery gross margins, throughput volumes and 
discount rate. Gross margin assumptions used in the Rhine FVC plan are consistent with those used to develop the regional Refining Marker Margin 
(RMM). The regional RMM is a margin measure based upon product yields and a marker crude oil deemed appropriate for the region. The average values 
assigned to the regional RMM and refinery throughput volume over the plan period are $11.35 per barrel and 257 million barrels per year (2010 $11.05 per 
barrel and 248 million barrels per year). These values reflect past experience and are consistent with external sources. Cash flows beyond the five-year 
plan period are extrapolated using a nominal 4% growth rate (2010 cash flows beyond the five-year plan period were extrapolated using a nominal 4% 
growth rate).

Sensitivity analysis

Lubricants
As permitted by IAS 36, the detailed calculations of the Lubricants unit’s recoverable amount performed in the most recent detailed calculation in 2009 
were used for the 2011 impairment test as the criteria in that standard were considered satisfied: the headroom was substantial in 2009; there have been 
no significant changes in the assets and liabilities; and the likelihood that the recoverable amount would be less than the carrying amount at the time of 
the test was remote.

The key assumptions to which the calculation of value in use for the Lubricants unit is most sensitive are operating unit margins, sales volumes 

and discount rate. The values assigned to these key assumptions reflect past experience. No reasonably possible changes in any of these key 
assumptions would cause the unit’s carrying amount to exceed its recoverable amount. Cash flows beyond the two-year plan period were extrapolated 
using a nominal 3% growth rate.

14. Operating leases

In the case of an operating lease entered into by BP as the operator of a jointly controlled asset, the amounts shown in the tables below represent the net 
operating lease expense and net future minimum lease payments. These net amounts are after deducting amounts reimbursed, or to be reimbursed, by 
joint venture partners, whether the joint venture partners have co-signed the lease or not. Where BP is not the operator of a jointly controlled asset, BP’s 
share of the lease expense and future minimum lease payments is included in the amounts shown, whether BP has co-signed the lease or not.

The table below shows the expense for the year in respect of operating leases.

as follows:

Ships

Commercial vehicles
Land and buildings

Years
up to 15
up to 10
up to 15
up to 40

The group has entered into a number of structured operating leases for ships and in most cases the lease rental payments vary with market interest rates. 
The variable portion of the lease payments above or below the amount based on the market interest rate prevailing at inception of the lease is treated as 
contingent rental expense. The group also routinely enters into bareboat charters, time-charters and spot-charters for ships on standard industry terms.

The most significant items of plant and machinery hired under operating leases are drilling rigs used in the Exploration and Production segment. At 

31 December 2011 the future minimum lease payments relating to drilling rigs amounted to $6,292 million (2010 $4,515 million). In some cases, drilling 
rig lease rental rates are adjusted periodically to market rates that are influenced by oil prices and may be significantly different from the rates at the 
inception of the lease. Differences between the rate paid and rate at inception of the lease are treated as contingent rental expense.

Commercial vehicles hired under operating leases are primarily railcars. Retail service station sites and office accommodation are the main items in 

the land and buildings category.

The terms and conditions of these operating leases do not impose any significant financial restrictions on the group. Some of the leases of ships 

and buildings allow for renewals at BP’s option, and some of the group’s operating leases contain escalation clauses.

2011 includes $1 million of additional fees for 2010 and 2010 includes $1 million of additional fees for 2009. Auditor’s remuneration is included in the 
income statement within distribution and administration expenses.

The tax services relate to income tax and indirect tax compliance, employee tax services and tax advisory services.
The audit committee has established pre-approval policies and procedures for the engagement of Ernst & Young to render audit and certain 

assurance and tax services. The audit fees payable to Ernst & Young are reviewed by the audit committee in the context of other global companies for 
cost-effectiveness. Ernst & Young performed further assurance and tax services that were not prohibited by regulatory or other professional requirements 
and were pre-approved by the committee. Ernst & Young is engaged for these services when its expertise and experience of BP are important. Most of 
this work is of an audit nature. Tax services were awarded either through a full competitive tender process or following an assessment of the expertise of 
Ernst & Young compared with that of other potential service providers. These services are for a fixed term.

Under SEC regulations, the remuneration of the auditor of $55 million (2010 $55 million and 2009 $54 million) is required to be presented as 

follows: audit $44 million (2010 $47 million and 2009 $46 million); other audit-related services $1 million (2010 $1 million and 2009 $2 million); tax 
$2 million (2010 $2 million and 2009 $1 million); and fees for all other services $8 million (2010 $5 million and 2009 $5 million).

Reconciliation of the effective tax rate
The following table provides a reconciliation of the UK statutory corporation tax rate to the effective tax rate of the group on profit or loss before taxation. 
With effect from 1 April 2011 the UK statutory corporation tax rate reduced from 28% to 26%.

For 2010, the items presented in the reconciliation are distorted as a result of the overall tax credit for the year and the loss before taxation. In 
order to provide a more meaningful analysis of the effective tax rate for 2010, the table also presents separate reconciliations for the group excluding 
the impacts of the Gulf of Mexico oil spill, and for the impacts of the Gulf of Mexico oil spill in isolation. For 2011, the effective tax rate is not impacted 
significantly by the Gulf of Mexico oil spill.

Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences 
and the carry-forward of unused tax credits and unused tax losses can be utilized.

At 31 December 2011, the group had approximately $4.6 billion (2010 $3.9 billion) of carry-forward tax losses that would be available to offset 
against future taxable profit. A deferred tax asset has been recognized in respect of $3.8 billion of losses (2010 $3.0 billion). No deferred tax asset has 
been recognized in respect of $0.8 billion of losses (2010 $0.9 billion). In 2011, a current tax benefit of $0.1 billion arose relating to losses utilized on which 
a deferred tax asset had not previously been recognized (2010 nil). Substantially all the tax losses have no fixed expiry date.

At 31 December 2011, the group had approximately $18.2 billion of unused tax credits predominantly in the UK and US (2010 $13.9 billion). 

At 31 December 2011 there is a deferred tax asset of $2.5 billion in respect of unused tax credits (2010 $2.1 billion). No deferred tax asset has been 
recognized in respect of $15.7 billion of tax credits (2010 $11.8 billion). In 2011, a current tax benefit of $0.1 billion arose relating to tax credits utilized on 
which a deferred tax asset had not previously been recognized (2010 $0.3 billion).

The UK tax credits, arising in UK branches overseas with no deferred tax asset, amounting to $13.0 billion (2010 $9.9 billion) do not have a 

fixed expiry date. In addition there are also temporary differences in overseas branches of UK companies with no deferred tax asset recognized. At 
31 December 2011 the unrecognized deferred tax amounted to $0.9 billion (2010 $0.9 billion). These credits and temporary differences arise in UK 
branches predominantly based in high tax rate jurisdictions and so are unlikely to have value in the future as UK taxes on these overseas branches are 
largely mitigated by the double tax relief on the local foreign tax.

The US tax credits with no deferred tax asset amounting to $2.7 billion (2010 $1.9 billion) expire 10 years after generation, and the majority expire 

in the period 2014-2021.

The group recognized significant costs in 2010 in relation to the Gulf of Mexico oil spill and in 2011 has recognized certain recoveries relating to the 

incident as well as further costs. Tax has been calculated on the expenditures that are expected to qualify for tax relief, and on the recoveries, at the US 
statutory tax rate. A deferred tax asset has been recognized in respect of provisions for future expenditure that are expected to qualify for tax relief. This is 
included under the heading decommissioning, environmental and other provisions.

The other major components of temporary differences at the end of 2011 relate to tax depreciation, provisions, including items relating to the Gulf 

of Mexico oil spill, US inventory holding gains (classified as other taxable temporary differences) and pension plan and other post-retirement benefit plan 
deficits.

At 31 December 2011, there were no material temporary differences associated with investments in subsidiaries and equity-accounted entities for 

which deferred tax liabilities have not been recognized.

In 2011, the enactment of a 12% increase in the UK supplementary charge on oil and gas production activities in the North Sea increased the 

deferred tax charge in the income statement by $713 million of which $683 million relates to the revaluation of the opening deferred tax balance.

Also in 2011, the enactment of a 2% reduction in the rate of UK corporation tax to 25% with effect from 1 April 2012 on profits arising from 
activities outside the North Sea reduced the deferred tax charge in the income statement by $120 million. In 2010 the enactment of a 1% reduction in the 
rate of UK corporation tax to 27% with effect from 1 April 2011 similarly reduced the deferred tax charge in the income statement by $86 million.

In 2012, legislation to restrict relief for UK decommissioning expenditure from 62% to 50% is expected to be enacted. New legislation is also likely 

to be introduced in Australia which would bring BP’s North West Shelf activities into the charge to Petroleum Resource Rent Tax (PRRT) from July 2012. 
The impacts of both of these changes are currently being assessed.

19. Dividends

The quarterly dividend expected to be paid on 30 March 2012 in respect of the fourth quarter 2011 is 8 cents per ordinary share ($0.48 per American 
Depositary Share (ADS)). The corresponding amount in sterling will be announced on 19 March 2012. A scrip dividend alternative is available, allowing 
shareholders to elect to receive their dividend in the form of new ordinary shares and ADS holders in the form of new ADSs.

On 1 February 2011 BP announced the resumption of quarterly dividend payments with a fourth-quarter 2010 dividend of 7 cents per share. The 

resumption came after the suspension of dividends for the first three quarters of 2010 in light of the Gulf of Mexico oil spill and commitments to fund the 
$20-billion Trust.

Basic earnings per ordinary share amounts are calculated by dividing the profit or loss for the year attributable to ordinary shareholders by the weighted 
average number of ordinary shares outstanding during the year. The average number of shares outstanding excludes treasury shares and the shares held 
by the Employee Share Ownership Plan Trusts (ESOPs) and includes certain shares that will be issuable in the future under employee share plans.

For the diluted earnings per share calculation, the weighted average number of shares outstanding during the year is adjusted for the number of 

shares that are potentially issuable in connection with employee share-based payment plans using the treasury stock method. If the inclusion of potentially 
issuable shares would decrease the loss per share, the potentially issuable shares are excluded from the diluted earnings per share calculation.

The number of ordinary shares outstanding at 31 December 2011, excluding treasury shares and the shares held by the ESOPs, and including certain 
shares that will be issuable in the future under employee share plans was 18,977,213,826. Between 31 December 2011 and 17 February 2012, the latest 
practicable date before the completion of these financial statements, there was a net increase of 379,374 in the number of ordinary shares outstanding 
as a result of share issues in relation to employee share plans. The number of potential ordinary shares issuable through the exercise of employee 
share plans was 254,106,576 at 31 December 2011. There has been a decrease of 53,225,107 in the number of potential ordinary shares between 
31 December 2011 and 17 February 2012.

The terms of the outstanding balances receivable from associates are typically 30 to 45 days. The balances are unsecured and will be settled in cash. 
There are no significant provisions for doubtful debts relating to these balances and no significant expense recognized in the income statement in respect 
of bad or doubtful debts.

The amounts receivable and payable at 31 December 2011, as shown in the table above, exclude $220 million (2010 $299 million) due from and 

due to an intermediate associate which provides funding for our associate The Baku-Tbilisi-Ceyhan Pipeline Company. These balances are expected to be 
settled in cash throughout the period to 2015.

Dividends receivable at 31 December 2011 of $38 million (2010 $39 million) are also excluded from the table above.
BP has commitments amounting to $1,477 million (2010 $310 million) in relation to contracts with its associates for the purchase of crude oil and 

oil products, transportation and storage. See Note 44 for further information on capital commitments relating to BP’s investments in associates.
On 18 October 2010, BP announced that it had reached agreement to sell assets in Vietnam, together with its upstream businesses and 

associated interests in Venezuela, to TNK-BP which is an associate and therefore a related party of the group. This transaction is part of the group’s 
disposal programme and is the result of normal commercial negotiations. As at 31 December 2010, a deposit of $1 billion had been received from  
TNK-BP in advance of completion of this transaction and was reported within finance debt on the group balance sheet. This deposit was not reflected 
in the amount payable in the table above. The sale of the Venezuelan business and the sale of the upstream and certain midstream assets in Vietnam 
completed during 2011. Additional disposal proceeds of $0.7 billion were received upon completion of these transactions. The sale of the group’s 
remaining equity-accounted investment in the Phu My 3 plant facility in Vietnam is expected to complete in 2012. See Note 4 for further information. 
A deposit of $30 million relating to the disposal of the Phu My 3 plant facility remains reported within finance debt on the group balance sheet at 
31 December 2011.

Financial risk factors
The group is exposed to a number of different financial risks arising from natural business exposures as well as its use of financial instruments including: 
market risks relating to commodity prices, foreign currency exchange rates, interest rates and equity prices; credit risk; and liquidity risk.

The group financial risk committee (GFRC) advises the group chief financial officer (CFO) who oversees the management of these risks. The GFRC 
is chaired by the CFO and consists of a group of senior managers including the group treasurer and the heads of the group finance, tax and the integrated 
supply and trading functions. The purpose of the committee is to advise on financial risks and the appropriate financial risk governance framework for the 
group. The committee provides assurance to the CFO and the group chief executive (GCE), and via the GCE to the board, that the group’s financial  
risk-taking activity is governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with 
group policies and group risk appetite.

The group’s trading activities in the oil, natural gas and power markets are managed within the integrated supply and trading function, while the 
activities in the financial markets are managed by the integrated supply and trading function, on behalf of the treasury function. All derivative activity is 
carried out by specialist teams that have the appropriate skills, experience and supervision. These teams are subject to close financial and management 
control.

The integrated supply and trading function maintains formal governance processes that provide oversight of market risk associated with 

trading activity. These processes meet generally accepted industry practice and reflect the principles of the Group of Thirty Global Derivatives Study 
recommendations. A policy and risk committee monitors and validates limits and risk exposures, reviews incidents and validates risk-related policies, 
methodologies and procedures. A commitments committee approves value-at-risk delegations, the trading of new products, instruments and strategies 
and material commitments.

In addition, the integrated supply and trading function undertakes derivative activity for risk management purposes under a separate control 

framework as described more fully below.

26. Financial instruments and financial risk factors continued

(a) Market risk
Market risk is the risk or uncertainty arising from possible market price movements and their impact on the future performance of a business. The primary 
commodity price risks that the group is exposed to include oil, natural gas and power prices that could adversely affect the value of the group’s financial 
assets, liabilities or expected future cash flows. The group enters into derivatives in a well-established entrepreneurial trading operation. In addition, the 
group has developed a control framework aimed at managing the volatility inherent in certain of its natural business exposures. In accordance with the 
control framework the group enters into various transactions using derivatives for risk management purposes.

The group measures market risk exposure arising from its trading positions using value-at-risk techniques. These techniques are based on Monte 
Carlo simulation and make a statistical assessment of the market risk arising from possible future changes in market prices over a one-day holding period. 
The calculation of the range of potential changes in fair value takes into account a snapshot of the end-of-day exposures and the history of one-day price 
movements, together with the correlation of these price movements. The value-at-risk measure is supplemented by stress testing.

The value-at-risk table does not incorporate any of the group’s natural business exposures or any derivatives entered into to risk manage those 

exposures. Market risk exposure in respect of embedded derivatives is also not included in the value-at-risk table.

Value-at-risk limits are in place for each trading activity and for the group’s trading activity in total. The board has delegated a limit of $100 million 

value at risk in support of this trading activity. The high and low values at risk indicated in the table below for each type of activity are independent of each 
other. Through the portfolio effect the high value at risk for the group as a whole is lower than the sum of the highs for the constituent parts. The potential 
movement in fair values is expressed to a 95% confidence interval. This means that, in statistical terms, one would expect to see a decrease in fair values 
greater than the trading value at risk on one occasion per month if the portfolio were left unchanged.

The major components of market risk are commodity price risk, foreign currency exchange risk, interest rate risk and equity price risk, each of which is 
discussed below.

(i) Commodity price risk
The group’s integrated supply and trading function uses conventional financial and commodity instruments and physical cargoes available in the related 
commodity markets. Oil and natural gas swaps, options and futures are used to mitigate price risk. Power trading is undertaken using a combination 
of over-the-counter forward contracts and other derivative contracts, including options and futures. This activity is on both a standalone basis and in 
conjunction with gas derivatives in relation to gas-generated power margin. In addition, NGLs are traded around certain US inventory locations using  
over-the-counter forward contracts in conjunction with over-the-counter swaps, options and physical inventories. Trading value-at-risk information in 
relation to these activities is shown in the table above.

As described above, the group also carries out risk management of certain natural business exposures using over-the-counter swaps and 
exchange futures contracts. Together with certain physical supply contracts that are classified as derivatives, these contracts fall outside of the value-at-
risk framework. For these derivative contracts the sensitivity of the net fair value to an immediate 10% increase or decrease in all reference prices would 
have been $23 million at 31 December 2011 (2010 $104 million). This figure does not include any corresponding economic benefit or disbenefit that 
would arise from the natural business exposure which would be expected to offset the gain or loss on the over-the-counter swaps and exchange futures 
contracts mentioned above.

In addition, the group has embedded derivatives relating to certain natural gas contracts. The net fair value of these contracts was a liability of 

$1,417 million at 31 December 2011 (2010 liability of $1,607 million). Key information on the natural gas contracts is given below.

Notes on financial statements26. Financial instruments and financial risk factors continued
The sensitivities for risk management activity and embedded derivatives are hypothetical and should not be considered to be predictive of future 
performance. In addition, for the purposes of this analysis, in the above table, the effect of a variation in a particular assumption on the fair value of the 
embedded derivatives is calculated independently of any change in another assumption. In reality, changes in one factor may contribute to changes in 
another, which may magnify or counteract the sensitivities. Furthermore, the estimated fair values as disclosed should not be considered indicative of 
future earnings on these contracts.

(ii) Foreign currency exchange risk
Where the group enters into foreign currency exchange contracts for entrepreneurial trading purposes the activity is controlled using trading value-at-risk 
techniques as explained above. This activity is included within oil price trading in the value-at-risk table above.

Since BP has global operations, fluctuations in foreign currency exchange rates can have significant effects on the group’s reported results. The 

effects of most exchange rate fluctuations are absorbed in business operating results through changing cost competitiveness, lags in market adjustment 
to movements in rates and translation differences accounted for on specific transactions. For this reason, the total effect of exchange rate fluctuations 
is not identifiable separately in the group’s reported results. The main underlying economic currency of the group’s cash flows is the US dollar. This is 
because BP’s major product, oil, is priced internationally in US dollars. BP’s foreign currency exchange management policy is to minimize economic 
and material transactional exposures arising from currency movements against the US dollar. The group co-ordinates the handling of foreign currency 
exchange risks centrally, by netting off naturally-occurring opposite exposures wherever possible, and then dealing with any material residual foreign 
currency exchange risks.

The group manages these exposures by constantly reviewing the foreign currency economic value at risk and aims to manage such risk to 

keep the 12-month foreign currency value at risk below $200 million. At 31 December 2011, the foreign currency value at risk was $100 million (2010 
$81 million). At no point over the past three years did the value at risk exceed the maximum risk limit. The most significant exposures relate to capital 
expenditure commitments and other UK and European operational requirements, for which a hedging programme is in place and hedge accounting is 
claimed as outlined in Note 33.

For highly probable forecast capital expenditures the group locks in the US dollar cost of non-US dollar supplies by using currency forwards and 
futures. The main exposures are sterling, euro, Norwegian krone, Australian dollar and Korean won and at 31 December 2011 open contracts were in 
place for $1,242 million sterling, $158 million euro, $118 million Norwegian krone, $210 million Australian dollar and $230 million Korean won capital 
expenditures maturing within five years, with over 69% of the deals maturing within two years (2010 $989 million sterling, $115 million euro, $212 million 
Norwegian krone and $143 million Australian dollar capital expenditures maturing within five years, with over 80% of the deals maturing within two years).

For other UK, European and Australian operational requirements the group uses cylinders and currency forwards to hedge the estimated 

exposures on a 12-month rolling basis. At 31 December 2011, the open positions relating to cylinders consisted of receive sterling, pay US dollar, 
purchased call and sold put options (cylinders) for $2,683 million (2010 $1,340 million); receive euro, pay US dollar cylinders for $1,304 million (2010 
$650 million); receive Australian dollar, pay US dollar cylinders for $312 million (2010 $286 million). At 31 December 2011 there were no open positions 
relating to currency forwards (2010 buy sterling, sell US dollar currency forwards for $925 million; buy euro, sell US dollar currency forwards for $630 
million; buy Canadian dollar, sell US dollar currency forwards for $162 million).

In addition, most of the group’s borrowings are in US dollars or are hedged with respect to the US dollar. At 31 December 2011, the total foreign 

currency net borrowings not swapped into US dollars amounted to $371 million (2010 $278 million). Of this total, $129 million was denominated in 
currencies other than the functional currency of the individual operating unit being entirely Canadian dollars (2010 $125 million, being entirely Canadian 
dollars). It is estimated that a 10% change in the corresponding exchange rates would result in an exchange gain or loss in the income statement of 
$13 million (2010 $12 million).

(iii) Interest rate risk
Where the group enters into money market contracts for entrepreneurial trading purposes the activity is controlled using value-at-risk techniques as 
described above. This activity is included within oil price trading in the value-at-risk table above.

BP is also exposed to interest rate risk from the possibility that changes in interest rates will affect future cash flows or the fair values of its 

financial instruments, principally finance debt.

While the group issues debt in a variety of currencies based on market opportunities, it uses derivatives to swap the debt to a floating rate 
exposure, mainly to US dollar floating, but in certain defined circumstances maintains a US dollar fixed rate exposure for a proportion of debt. The 
proportion of floating rate debt net of interest rate swaps and excluding disposal deposits at 31 December 2011 was 65% of total finance debt 
outstanding (2010 62%). The weighted average interest rate on finance debt at 31 December 2011 is 2% (2010 2%) and the weighted average maturity 
of fixed rate debt is five years (2010 five years).

The group’s earnings are sensitive to changes in interest rates on the floating rate element of the group’s finance debt. If the interest rates 

applicable to floating rate instruments were to have increased by 1% on 1 January 2012, it is estimated that the group’s profit before taxation for 2012 
would decrease by approximately $289 million (2010 $241 million decrease in 2011). This assumes that the amount and mix of fixed and floating rate 
debt, including finance leases, remains unchanged from that in place at 31 December 2011 and that the change in interest rates is effective from the 
beginning of the year. Where the interest rate applicable to an instrument is reset during a quarter it is assumed that this occurs at the beginning of the 
quarter and remains unchanged for the rest of the year. In reality, the fixed/floating rate mix will fluctuate over the year and interest rates will change 
continually. Furthermore, the effect on earnings shown by this analysis does not consider the effect of any other changes in general economic activity that 
may accompany such an increase in interest rates.

(iv) Equity price risk
The group holds equity investments, typically made for strategic purposes, that are classified as non-current available-for-sale financial assets and are 
measured initially at fair value with changes in fair value recognized in other comprehensive income. Accumulated fair value changes are recycled to the 
income statement on disposal, or when the investment is impaired. No impairment losses have been recognized for the years presented relating to listed 
non-current available-for-sale investments. For further information see Note 27.

At 31 December 2011, it is estimated that an increase of 10% in quoted equity prices would result in an immediate credit to other comprehensive 

income of $87 million (2010 $95 million credit to other comprehensive income), while a decrease of 10% in quoted equity prices would result in an 
immediate charge to other comprehensive income of $87 million (2010 $95 million charge to other comprehensive income).

BP Annual Report and Form 20-F 2011    219

Financial statementsNotes on financial statements26. Financial instruments and financial risk factors continued
At 31 December 2011, 77% (2010 80%) of the carrying amount of non-current available-for-sale equity financial assets represented the group’s stake in 
Rosneft, thus the group’s exposure is concentrated on changes in the share price of this equity investment in particular.

(b) Credit risk
Credit risk is the risk that a customer or counterparty to a financial instrument will fail to perform or fail to pay amounts due causing financial loss to 
the group and arises from cash and cash equivalents, derivative financial instruments and deposits with financial institutions and principally from credit 
exposures to customers relating to outstanding receivables.

The group has a credit policy, approved by the CFO, that is designed to ensure that consistent processes are in place throughout the group to 
measure and control credit risk. Credit risk is considered as part of the risk-reward balance of doing business. On entering into any business contract 
the extent to which the arrangement exposes the group to credit risk is considered. Key requirements of the policy are formal delegated authorities to 
the sales and marketing teams to incur credit risk and to a specialized credit function to set counterparty limits; the establishment of credit systems and 
processes to ensure that counterparties are rated and limits set; and systems to monitor exposure against limits and report regularly on those exposures, 
and immediately on any excesses, and to track and report credit losses. The treasury function provides a similar credit risk management activity with 
respect to group-wide exposures to banks and other financial institutions.

The global credit environment exhibited deterioration in 2011, suffering not only from continuing economic and political uncertainties but also from 

key event risks, causing the group to further heighten awareness, discussion and co-ordination around the material credit risks arising from its activities.

Before trading with a new counterparty can start, its creditworthiness is assessed and a credit rating is allocated that indicates the probability 

of default, along with a credit exposure limit. The assessment process takes into account all available qualitative and quantitative information about 
the counterparty and the group, if any, to which the counterparty belongs. The counterparty’s business activities, financial resources and business risk 
management processes are taken into account in the assessment, to the extent that this information is publicly available or otherwise disclosed to BP by 
the counterparty, together with external credit ratings. Creditworthiness continues to be evaluated after transactions have been initiated and a watchlist of 
higher-risk counterparties is maintained.

The group does not aim to remove credit risk but expects to experience a certain level of credit losses. The group attempts to mitigate credit 

risk by entering into contracts that permit netting and allow for termination of the contract on the occurrence of certain events of default. Depending on 
the creditworthiness of the counterparty, the group may require collateral or other credit enhancements such as cash deposits, letters of credit, trade 
credit insurance, liens, third-party guarantees and other forms of credit mitigation. Trade receivables and payables, and derivative assets and liabilities, 
are presented on a net basis where unconditional netting arrangements are in place with counterparties and where there is an intent to settle amounts 
due on a net basis. The maximum credit exposure associated with financial assets is equal to the carrying amount. Collateral received and recognized 
in the balance sheet at the year end was $273 million (2010 $313 million) and collateral held off balance sheet was $6 million (2010 $52 million). As at 
31 December 2011, the group had in place other credit enhancements designed to mitigate approximately $8.6 billion of credit risk (2010 $7.0 billion). 
Credit exposure exists in relation to guarantees issued by group companies under which amounts outstanding at 31 December 2011 were $415 million 
(2010 $404 million) in respect of liabilities of jointly controlled entities and associates and $1,430 million (2010 $1,339 million) in respect of liabilities of 
other third parties.

Notwithstanding the processes described above, significant unexpected credit losses can occasionally occur. Exposure to unexpected losses 

increases with concentrations of credit risk that exist when a number of counterparties are involved in similar activities or operate in the same industry 
sector or geographical area, which may result in their ability to meet contractual obligations being impacted by changes in economic, political or other 
conditions. The group’s principal customers, suppliers and financial institutions with which it conducts business are located throughout the world. In 
addition, these risks are managed by maintaining a group watchlist and aggregating multi-segment exposures to ensure that a material credit risk is 
not missed.

Reports are regularly prepared and presented to the GFRC that cover the group’s overall credit exposure and expected loss trends, exposure by 

segment, and overall quality of the portfolio. The reports also include details of the largest counterparties by exposure level and expected loss, and details 
of counterparties on the group watchlist.

For the contracts comprising derivative financial instruments in an asset position at 31 December 2011, it is estimated that over 76% (2010 over 

80%) of the unmitigated credit exposure is to counterparties of investment grade credit quality.

For cash and cash equivalents, the treasury function dynamically manages bank deposit limits to ensure cash is well-diversified and to reduce 
concentration risks. At 31 December 2011, 98% of the cash and cash equivalents balance was deposited with financial institutions rated at least A by 
Standard & Poor’s and A2 by Moody’s. Direct cash and cash equivalent exposures to Greek, Italian, Irish, Portuguese and Spanish financial institutions 
totalled less than 1% of total cash and cash equivalents.

Trade and other receivables of the group are analysed in the table below. By comparing the BP credit ratings to the equivalent external credit 

ratings, it is estimated that approximately 70-80% (2010 approximately 50-60%) of the unmitigated trade receivables portfolio exposure is of investment 
grade credit quality. With respect to the trade and other receivables that are neither impaired nor past due, there are no indications as of the reporting 
date that the debtors will not meet their payment obligations.

(c) Liquidity risk
Liquidity risk is the risk that suitable sources of funding for the group’s business activities may not be available. The group’s liquidity is managed centrally 
with operating units forecasting their cash and currency requirements to the central treasury function. Unless restricted by local regulations, subsidiaries 
pool their cash surpluses to treasury, which will then arrange to fund other subsidiaries’ requirements, or invest any net surplus in the market or arrange 
for necessary external borrowings, while managing the group’s overall net currency positions.

In managing its liquidity risk, the group has access to a wide range of funding at competitive rates through capital markets and banks. The group’s 

treasury function centrally co-ordinates relationships with banks, borrowing requirements, foreign exchange requirements and cash management. The 
group believes it has access to sufficient funding through its own current cash holdings and future cash generation including disposal proceeds, the 
commercial paper markets and by using undrawn committed borrowing facilities to meet foreseeable liquidity requirements.

The group has in place a European Debt Issuance Programme (DIP) under which the group may raise up to $20 billion of debt for maturities of 

one month or longer. At 31 December 2011, the amount drawn down against the DIP was $11,582 million (2010 $12,272 million). In addition, the group 
has in place an unlimited US Shelf Registration under which it may raise debt with maturities of one month or longer.

The group has long-term debt ratings of A2 (stable outlook) assigned by Moody’s consistently throughout the year, and A (stable outlook) assigned 

by Standard & Poor’s since July 2011, strengthened from A (negative outlook) in force at the start of the year.

During 2011 $10.7 billion of long-term taxable bonds were issued with tenors of between 18 months and 10 years, and $0.8 billion of US 
Industrial/Municipal bonds were re-issued in term-out mode of between three and ten years. Flexible commercial paper is issued at competitive rates to 
meet short-term borrowing requirements as and when needed.

As a further liquidity measure, the group continues to maintain suitable levels of cash and cash equivalents, invested with highly rated banks or 

money market funds and readily accessible at immediate and short notice ($14.1 billion at the end of 2011; $18.6 billion at the end of 2010).

At 31 December 2011, the group had substantial amounts of undrawn borrowing facilities available, consisting of $6,925 million of standby 

facilities (of which $6,825 million is available to draw and repay until mid-March 2014, and the equivalent of $100 million is available to draw and repay 
in Chinese yuan with half expiring in mid-September 2012 and half in December 2012). These facilities were renegotiated during 2011 across 25 
international banks, and borrowings under them would be at pre-agreed rates.

The group also has committed letter of credit (LC) facilities totalling $5,125 million with a number of banks for a one-year duration, allowing LCs 
to be issued to a maximum one-year duration. There were also uncommitted secured LC evergreen facilities in place at the year end for $2,160 million, 
secured against inventories or receivables when utilized.

The amounts shown for finance debt in the table below include expected interest payments on borrowings and the future minimum lease 

payments with respect to finance leases.

Current finance debt on the group balance sheet at 31 December 2011 includes $30 million (2010 $6,197 million) in respect of cash deposits 

received for disposals expected to complete in 2012, which will be considered extinguished on completion of the transactions. This amount is excluded 
from the table below.

The table also shows the timing of cash outflows relating to trade and other payables and accruals.

Financial statementsNotes on financial statements26. Financial instruments and financial risk factors continued
The group manages liquidity risk associated with derivative contracts, other than derivative hedging instruments, based on the expected maturities of both 
derivative assets and liabilities as indicated in Note 33. Management does not currently anticipate any cash flows that could be of a significantly different 
amount, or could occur earlier than the expected maturity analysis provided.

The table below shows cash outflows for derivative hedging instruments based upon contractual payment dates. The amounts reflect the 
maturity profile of the fair value liability where the instruments will be settled net, and the gross settlement amount where the pay leg of a derivative will 
be settled separately from the receive leg, as in the case of cross-currency interest rate swaps hedging non-US dollar finance debt. The swaps are with 
high investment-grade counterparties and therefore the settlement day risk exposure is considered to be negligible. Not shown in the table are the gross 
settlement amounts for the receive leg of derivatives that are settled separately from the pay leg, which amount to $9,099 million at 31 December 2011 
(2010 $6,725 million) to be received on the same day as the related cash outflows.

Equity investments have no fixed maturity date or coupon rate, and are classified as available-for-sale financial assets. As such they are recorded at fair 
value with the gain or loss arising as a result of changes in fair value recorded directly in other comprehensive income. Accumulated fair value changes are 
recycled to the income statement on disposal, or when the investment is impaired.

The fair value of listed investments has been determined by reference to quoted market bid prices and as such are in level 1 of the fair value 

hierarchy. Unlisted investments are stated at cost less accumulated impairment losses.

The most significant listed investment is the group’s stake in Rosneft which had a fair value of $873 million at 31 December 2011 (2010 

$948 million). The fair value loss arising on revaluation of this investment during 2011 has been recorded within other comprehensive income.

In 2011, impairment losses of $12 million were incurred relating to unlisted investments; there were no impairment losses relating to listed 

investments. In 2010, no impairment losses were incurred relating to either unlisted investments or listed investments.

BP has entered into long-term gas supply contracts which are backed by gas pre-paid bonds. In 2010, BP was unsuccessful in the remarketing of 

these bonds and repurchased them. The outstanding bonds associated with these long-term gas supply contracts held by BP are recorded within other 
investments, with the related liability recorded within other payables on the balance sheet. The fair value of the gas pre-paid bonds is the same as the 
carrying amount, as the bonds are based on floating rate interest with weekly market re-set, and as such are in Level 1 of the fair value hierarchy.
BP has no investments pledged as security for liabilities as at 31 December 2011. As at 31 December 2010, BP had pledged listed equity 
investments with a carrying value of $948 million as part of a financing arrangement. As BP had retained substantially all the risks and rewards associated 
with the shares, they continued to be reflected as an asset on the balance sheet, with a liability being reflected within finance debt. The terms of the 
arrangement meant that BP could request to have the shares returned at any time with 20 days notice, up to the date of maturity (in three tranches, up to 
December 2013), subject to repayment of the outstanding loan. The financing arrangement was terminated during 2011.

Cash and cash equivalents comprise cash in hand; current balances with banks and similar institutions; term deposits of three months or less with banks 
and similar institutions; and short-term highly liquid investments that are readily convertible to known amounts of cash, are subject to insignificant risk of 
changes in value and have a maturity of three months or less from the date of acquisition. The carrying amounts of cash at bank and in hand and term 
bank deposits approximate their fair values. All of the other cash equivalents are categorized within level 1 of the fair value hierarchy.

Cash and cash equivalents at 31 December 2011 includes $901 million (2010 $982 million) that is restricted. This relates principally to amounts 

required to cover initial margins on trading exchanges.

33. Derivative financial instruments

An outline of the group’s financial risks and the objectives and policies pursued in relation to those risks is set out in Note 26.

In the normal course of business the group enters into derivative financial instruments (derivatives) to manage its normal business exposures in 
relation to commodity prices, foreign currency exchange rates and interest rates, including management of the balance between floating rate and fixed 
rate debt, consistent with risk management policies and objectives. Additionally, the group has a well-established entrepreneurial trading operation that is 
undertaken in conjunction with these activities using a similar range of contracts.

IAS 39 prescribes strict criteria for hedge accounting, whether as a cash flow or fair value hedge or a hedge of a net investment in a foreign 
operation, and requires that any derivative that does not meet these criteria should be classified as held for trading and fair valued, with gains and losses 
recognized in the income statement.

Notes on financial statements33. Derivative financial instruments continued

Derivatives held for trading
The group maintains active trading positions in a variety of derivatives. The contracts may be entered into for risk management purposes, to satisfy supply 
requirements or for entrepreneurial trading. Certain contracts are classified as held for trading, regardless of their original business objective, and are 
recognized at fair value with changes in fair value recognized in the income statement. Trading activities are undertaken by using a range of contract types 
in combination to create incremental gains by arbitraging prices between markets, locations and time periods. The net of these exposures is monitored 
using market value-at-risk techniques as described in Note 26.

The following tables show further information on the fair value of derivatives and other financial instruments held for trading purposes. 

Derivative assets held for trading have the following fair values and maturities.

If at inception of a contract the valuation cannot be supported by observable market data, any gain or loss determined by the valuation methodology is not 
recognized in the income statement but is deferred on the balance sheet and is commonly known as ‘day-one profit or loss’. This deferred gain or loss 
is recognized in the income statement over the life of the contract until substantially all of the remaining contract term can be valued using observable 
market data at which point any remaining deferred gain or loss is recognized in the income statement. Changes in valuation from this initial valuation are 
recognized immediately through the income statement.

The following table shows the fair value of derivative assets and derivative liabilities held for trading, analysed by maturity period and by methodology of 
fair value estimation.

IFRS 7 ‘Financial Instruments: Disclosures’ sets out a fair value hierarchy which consists of three levels that describe the methodology of 

estimation as follows:

Level 1 – using quoted prices in active markets for identical assets or liabilities.
Level 2 –  using inputs for the asset or liability, other than quoted prices, that are observable either directly (i.e. as prices) or indirectly  

(i.e. derived from prices).

Level 3 –  using inputs for the asset or liability that are not based on observable market data such as prices based on internal models or other 

valuation methods.

This information is presented on a gross basis, that is, before netting by counterparty.

Transfers out of level 3 of the fair value hierarchy in 2011 relate primarily to the delivery dates for a number of natural gas forward contracts moving into a 
time period where market observable prices are available, and therefore being reclassified to level 2 of the fair value hierarchy.

The amount recognized in the income statement for the year relating to level 3 held for trading derivatives still held at 31 December 2011 was a 

$204 million gain (2010 $651 million gain relating to derivatives still held at 31 December 2010).

Gains and losses relating to derivative contracts are included either within sales and other operating revenues or within purchases in the income 

statement depending upon the nature of the activity and type of contract involved. The contract types treated in this way include futures, options, 
swaps and certain forward sales and forward purchases contracts, and relate to both currency and commodity trading activities. Gains or losses arise 
on contracts entered into for risk management purposes, optimization activity and entrepreneurial trading. They also arise on certain contracts that are 
for normal procurement or sales activity for the group but that are required to be fair valued under accounting standards. Also included within sales and 
other operating revenues are gains and losses on inventory held for trading purposes. The total amount relating to all of these items was a net loss of 
$934 million (2010 $1,738 million net gain and 2009 $4,046 million net gain).

Embedded derivatives
The group has embedded derivatives relating to certain natural gas contracts. Prior to the development of an active gas trading market, UK gas contracts 
were priced using a basket of available price indices, primarily relating to oil products, power and inflation. After the development of an active UK gas 
market, certain contracts were entered into or renegotiated using pricing formulae not directly related to gas prices, for example, oil product and power 
prices. In these circumstances, pricing formulae have been determined to be derivatives, embedded within the overall contractual arrangements that are 
not clearly and closely related to the underlying commodity. The resulting fair value relating to these contracts is recognized on the balance sheet with 
gains or losses recognized in the income statement.

All the commodity price embedded derivatives relate to natural gas contracts, are categorized in level 3 of the fair value hierarchy and are valued 

using inputs that include price curves for each of the different products that are built up from active market pricing data. Where necessary, these are 
extrapolated to the expiry of the contracts (the last of which is in 2018) using all available external pricing information. Additionally, where limited data 
exists for certain products, prices are interpolated using historic and long-term pricing relationships.

In addition, at 31 December 2010, BP was party to a collar-backed financing arrangement involving an available-for-sale investment held by the 
group. This arrangement contained an embedded derivative whose fair value was related to the equity price of the investment and was categorized in 
level 2 of the fair value hierarchy. The arrangement was terminated in 2011.

Cash flow hedges
At 31 December 2011, the group held currency forwards and futures contracts and cylinders that were being used to hedge the foreign currency risk of 
highly probable forecast transactions. Note 26 outlines the management of risk aspects for currency risk. For cash flow hedges the group only claims 
hedge accounting for the intrinsic value on the currency with any fair value attributable to time value taken immediately to the income statement. 
There were no highly probable transactions for which hedge accounting has been claimed that have not occurred and no significant element of hedge 
ineffectiveness requiring recognition in the income statement. For cash flow hedges the pre-tax amount removed from equity during the period and 
included in the income statement is a gain of $195 million (2010 gain of $25 million and 2009 loss of $366 million). The entire gain of $195 million is 
included in production and manufacturing expenses (2010 $25 million gain in production and manufacturing expense; 2009 $332 million loss in production 
and manufacturing expense and $34 million loss in finance costs). The amount removed from equity during the period and included in the carrying amount 
of non-financial assets was a gain of $13 million (2010 $53 million loss and 2009 $136 million loss).

The amounts retained in equity at 31 December 2011 consist of deferred losses of $78 million maturing in 2012, deferred losses of $39 million 

maturing in 2013 and deferred losses of $30 million maturing in 2014 and beyond.

Fair value hedges
At 31 December 2011, the group held interest rate and cross-currency interest rate swap contracts as fair value hedges of the interest rate risk on 
fixed rate debt issued by the group. The effectiveness of each hedge relationship is quantitatively assessed and demonstrated to continue to be highly 
effective. The gain on the hedging derivative instruments taken to the income statement in 2011 was $328 million (2010 $563 million gain and 2009 $98 
million loss) offset by a loss on the fair value of the finance debt of $327 million (2010 $554 million loss and 2009 $117 million gain).

The interest rate and cross-currency interest rate swaps mature within one to 10 years, with an average maturity of four to five years (2010 four 
to five years) and are used to convert sterling, euro, Swiss franc, Australian dollar, Japanese yen and Hong Kong dollar denominated borrowings into US 
dollar floating rate debt. Note 26 outlines the group’s approach to interest rate and currency risk management.

Current finance debt includes the portion of long-term borrowings and net obligations under finance leases that will mature in the next 12 months, 
amounting to $5,214 million (2010 $6,976 million).

The main elements of current borrowings are the current portion of long-term bonds of $4,875 million (2010 $6,859 million) and issued commercial 

paper of $3,635 million (2010 $1,025 million).

Deposits for disposal transactions expected to complete in 2012 of $30 million are also included in current finance debt (2010 $6,197 million for 

transactions expected to complete in 2011). This debt will be considered extinguished on completion of the transactions.

At 31 December 2011, $131 million (2010 $790 million) of finance debt was secured by the pledging of assets, and no finance debt was secured in 

connection with deposits received relating to certain disposal transactions expected to complete in subsequent periods (2010 $4,780 million). In addition, 
in connection with $2,344 million (2010 $4,588 million) of finance debt, BP has entered into crude oil sales contracts in respect of oil produced from 
certain fields in offshore Angola and Azerbaijan to provide security to the lending banks. The remainder of finance debt was unsecured.

The following table shows, by major currency, the group’s finance debt at 31 December and the weighted average interest rates achieved at those 
dates through a combination of borrowings and derivative financial instruments entered into to manage interest rate and currency exposures. The disposal 
deposits noted above are excluded from this analysis.

Finance leases
The group uses finance leases to acquire property, plant and equipment. These leases have terms of renewal but no purchase options and escalation 
clauses. Renewals are at the option of the lessee. The terms and conditions of these finance leases do not impose any significant financial restrictions on 
the group. Future minimum lease payments under finance leases are set out below.

Fair values
The estimated fair value of finance debt is shown in the table below together with the carrying amount as reflected in the balance sheet.

Long-term borrowings in the table below include the portion of debt that matures in the year from 31 December 2011, whereas in the balance 

sheet the amount would be reported within current finance debt. The disposal deposits noted above are excluded from this analysis.

The carrying amount of the group’s short-term borrowings, comprising mainly commercial paper, approximates their fair value. The fair value of 

the group’s long-term borrowings and finance lease obligations is estimated using quoted prices or, where these are not available, discounted cash flow 
analyses based on the group’s current incremental borrowing rates for similar types and maturities of borrowing.

35. Capital disclosures and analysis of changes in net debt

The group defines capital as total equity. The group’s approach to managing capital is set out in its financial framework which BP continues to refine to 
support the pursuit of value growth for shareholders, while maintaining a secure financial base. We intend to maintain a significant liquidity buffer and to 
reduce our net debt ratio to the lower half of the 10-20% gearing range over time as our disposal programme progresses.

The group monitors capital on the basis of the net debt ratio, that is, the ratio of net debt to net debt plus equity. Net debt is calculated as gross 
finance debt, as shown in the balance sheet, plus the fair value of associated derivative financial instruments that are used to hedge foreign exchange 
and interest rate risks relating to finance debt, for which hedge accounting is applied, less cash and cash equivalents. Net debt and net debt ratio are 
non-GAAP measures. BP believes these measures provide useful information to investors. Net debt enables investors to see the economic effect of 
gross debt, related hedges and cash and cash equivalents in total. The net debt ratio enables investors to see how significant net debt is relative to equity 
from shareholders. The derivatives are reported on the balance sheet within the headings ‘Derivative financial instruments’. All components of equity are 
included in the denominator of the calculation. At 31 December 2011 the net debt ratio was 20.5% (2010 21.2%).

During 2011 and 2010, the company did not repurchase any of its own shares, other than to satisfy the requirements of certain employee

The group makes full provision for the future cost of decommissioning oil and natural gas wells, facilities and related pipelines on a discounted basis upon 
installation. The provision for the costs of decommissioning these wells, production facilities and pipelines at the end of their economic lives has been 
estimated using existing technology, at current prices or future assumptions, depending on the expected timing of the activity, and discounted using a real 
discount rate of 0.5% (2010 1.5%). These costs are generally expected to be incurred over the next 30 years. While the provision is based on the best 
estimate of future costs and the economic lives of the facilities and pipelines, there is uncertainty regarding both the amount and timing of these costs.

Provisions for environmental remediation are made when a clean-up is probable and the amount of the obligation can be estimated reliably. 

Generally, this coincides with commitment to a formal plan of action or, if earlier, on divestment or on closure of inactive sites. The provision for 
environmental liabilities has been estimated using existing technology, at current prices and discounted using a real discount rate of 0.5% (2010 1.5%). 
The majority of these costs are expected to be incurred over the next 10 years. The extent and cost of future remediation programmes are inherently 
difficult to estimate. They depend on the scale of any possible contamination, the timing and extent of corrective actions, and also the group’s share of 
the liability.

The litigation category includes provisions for matters related to, for example, commercial disputes, product liability, and allegations of exposures 

of third parties to toxic substances. Included within the other category at 31 December 2011 are provisions for deferred employee compensation of 
$666 million (2010 $728 million). These provisions are discounted using either a nominal discount rate of 2.5% (2010 3.75%) or a real discount rate of 
0.5% (2010 1.5%), as appropriate.

As described in Note 2, BP has recorded provisions at 31 December 2011 relating to the Gulf of Mexico oil spill including amounts in relation to 
environmental expenditure, spill response costs, litigation and claims, and Clean Water Act penalties, each of which is described below. The total amounts 
that will ultimately be paid by BP are subject to significant uncertainty as described in Note 2.

Subsequent to BP releasing its preliminary announcement of the fourth quarter 2011 results on 7 February 2012, BP announced on 3 March 2012 
that it had reached a proposed settlement with the Plaintiffs’ Steering Committee (PSC), subject to final written agreement and court approvals, to resolve 
the substantial majority of legitimate economic loss and medical claims stemming from the Deepwater Horizon accident and oil spill. The proposed 
settlement has been reflected in the financial statements for 2011 included in this report. 

Certain items are subject to settlement discussions or may be subject to settlement discussions in the future. Any further settlements which may 

be reached relating to the Deepwater Horizon accident and oil spill could impact the amount and timing of any future payments.

Environmental
The amounts committed by BP for a 10-year research programme to study the impact of the incident on the marine and shoreline environment of the 
Gulf of Mexico have been provided for. BP’s commitment is to provide $500 million of funding, and the remaining commitment, on a discounted basis, of 
$421 million was included in provisions at 31 December 2011. This amount is expected to be spent over the remaining life of the programme.

As a responsible party under the Oil Pollution Act of 1990 (OPA 90), BP faces claims by the United States, as well as by State, tribal, and foreign 
trustees, if any, for natural resource damages (“Natural Resource Damages claims”). These damages include, among other things, the reasonable costs 
of assessing the injury to natural resources as well as some emergency restoration projects which are expected to occur over the next two years. BP 
has been incurring natural resource damage assessment costs and a provision has been made for the estimated costs of the assessment phase. The 
assessment covers a large area of potential impact and will take some time to complete in order to determine both the severity and duration of the 
impact of the oil spill. The process of interpreting the large volume of data collected is expected to take at least several months and, in order to determine 
potential injuries to certain animal populations, data will need to be collected over one or more reproductive cycles. This expected assessment spend is 
based upon past experience as well as identified projects. During 2011, BP entered a framework agreement with natural resource trustees for the United 
States and five Gulf Coast states, providing for up to $1 billion to be spent on early restoration projects to address natural resource injuries resulting from 
the Gulf of Mexico oil spill. Funding for these projects will come from the $20-billion trust fund. The total amount provided for these items was $1,096 
million at 31 December 2011. Until the size, location and duration of the impact is assessed, it is not possible to estimate reliably either the amounts 
or timing of the remaining Natural Resource Damages claims other than the emergency and early restoration agreements noted above, therefore no 
amounts have been provided for these items and they are disclosed as a contingent liability. See Note 43 for further information.

Spill response
Further amounts were provided relating to the spill response during 2011, totalling $0.6 billion. This primarily reflected increased costs of shoreline 
clean-up, patrolling and maintenance and vessel decontamination. The majority of the active clean-up of the shorelines had been completed by the end of 
the year.

Litigation and claims
Individual and Business Claims, and State and Local Claims under the Oil Pollution Act of 1990 (OPA 90) and claims for personal injury 
BP faces claims under OPA 90 by individuals and businesses for removal costs, damage to real or personal property, lost profits or impairment of  
earning capacity, loss of subsistence use of natural resources and for personal injury (“Individual and Business Claims”) and by state and local government 
entities for removal costs, physical damage to real or personal property, loss of government revenue and increased public services costs  
(“State and Local Claims”).

The estimated future cost of settling Individual and Business Claims, State and Local Claims under OPA 90 and claims for personal injuries, both 

reported and unreported, has been provided for. Claims administration costs and legal fees have also been provided for.

Subsequent to BP releasing its preliminary announcement of the fourth quarter 2011 results on 7 February 2012, BP announced on 3 March 

2012 that it had reached a proposed settlement with the PSC, subject to final written agreement and court approvals, to resolve the substantial majority 
of legitimate economic loss and medical claims stemming from the Deepwater Horizon accident and oil spill. The details of the proposed settlement 
agreement are explained in Legal proceedings on pages 160 to 164.

In 2010 and for the 2011 preliminary results, BP believed that the history of claims received, and settlements made, provided sufficient data to 

enable the company to use an approach based on a combination of actuarial methods and management judgements to estimate IBNR (Incurred But Not 
Reported) claims to determine a reliable best estimate of BP’s exposure for claims not yet reported in relation to Individual and Business claims, and State 
and Local claims under OPA 90. The amount provided for these claims was determined in accordance with IFRS and represented BP’s best estimate of 
the expenditure required to settle its obligations at the balance sheet date.

In estimating the amount of the provision, BP determined a range of possible outcomes for Individual and Business Claims, and State and Local 

Claims. As disclosed in the preliminary announcement of the fourth quarter 2011 results, BP had concluded that a reasonable range of possible outcomes 
for the amount of the provision as at 31 December 2011 was $4.1 billion to $8.3 billion. This range was for claims payable through the Gulf Coast Claims 
Facility and State and Local Claims only.

232    BP Annual Report and Form 20-F 2011

Notes on financial statements36. Provisions continued

Following the proposed settlement agreement entered into with the PSC, subject to final written agreement and court approvals, BP reviewed 

the amount of the provision for the items covered by the proposed settlement based upon information available at the time that the consolidated financial 
statements were approved. The provision for these items at 31 December 2011 is now $7.8 billion which represents a reliable best estimate of the 
liability under the proposed settlement agreement which, under accounting standards, is the amount that BP would rationally pay to settle the obligation. 
Substantially all of this amount is included as payable from the trust fund under Litigation and claims in the table above. Future claims administration 
costs are expected to be paid from the trust fund. However, at this time, the provision for these costs is shown as payable from outside the trust fund, 
consistent with how the administration costs associated with the GCCF were treated, as the proposed settlement is subject to final written agreement 
and court approvals. Further information on the proposed settlement with the PSC is included in Legal proceedings on pages 160 to 164.

The provision is in addition to the $6.3 billion of claims paid in total ($2.9 billion in 2011 and $3.4 billion in 2010). Of this total paid, $6.1 billion is 
included within utilization of provision in the table ($2.9 billion in 2011 and $3.2 billion in 2010), and the remaining $0.2 billion was a period expenditure 
prior to the recognition of the provision at the end of the second quarter 2010. Also included within the utilization of the provision of $4.4 billion (2010 $4.0 
billion) under Litigation and claims in the table are amounts relating to claims administration costs, legal fees and other settlements. Of the total payments 
of $6.3 billion, $5.9 billion was paid out of the trust fund ($2.9 billion in 2011 and $3.0 billion in 2010) and $0.4 billion was paid by BP in 2010.

Many key assumptions underlie and influence the reliable best estimates of total expenditures derived for both categories of claims. The amount 
provided for Individual and Business Claims is based upon the expected terms of the proposed settlement with the PSC, which is subject to final written 
agreement and court approvals. Other key assumptions include the amounts that will ultimately be paid in relation to current claims, the number, type 
and amounts for claims not yet reported, the outcomes of any further litigation through potential opt-outs from the proposed settlement and the amount 
of administration and other costs associated with the proposed settlement. While BP has determined a reliable best estimate of the cost of the proposed 
settlement with the PSC, it is possible that the actual cost could be higher or lower than this estimate.

The outcomes of claims and litigation are likely to be paid out over many years to come. BP will re-evaluate the assumptions underlying this 

analysis on a quarterly basis as more information becomes available and the claims process matures.

BP also faces other litigation for which no reliable estimate of the cost can currently be made. Therefore no amounts have been provided for these 

items. See Note 43 for further information.

Clean Water Act penalties
A provision has been made for the estimated penalties for strict liability under Section 311 of the Clean Water Act. Such penalties are subject to a 
statutory maximum calculated as the product of a per-barrel maximum penalty rate and the number of barrels of oil spilled. Uncertainties currently exist in 
relation to both the per-barrel penalty rate that will ultimately be imposed and the volume of oil spilled.

A charge for potential Clean Water Act Section 311 penalties was first included in BP’s second-quarter 2010 interim financial statements. At the 
time that charge was taken, the latest estimate from the intra-agency Flow Rate Technical Group created by the National Incident Commander in charge 
of the spill response was between 35,000 and 60,000 barrels per day. The mid-point of that range, 47,500 barrels per day, was used for the purposes 
of calculating the charge. For the purposes of calculating the amount of the oil flow that was discharged into the Gulf of Mexico, the amount of oil that 
had been or was projected to be captured in vessels on the surface was subtracted from the total estimated flow up until when the well was capped on 
15 July 2010. The result of this calculation was an estimate that approximately 3.2 million barrels of oil had been discharged into the Gulf. This estimate 
of 3.2 million barrels was calculated using a total flow of 47,500 barrels per day multiplied by the 85 days from 22 April 2010 through 15 July 2010 less an 
estimate of the amount captured on the surface (then estimated at approximately 850,000 barrels).

This estimated discharge volume was then multiplied by $1,100 per barrel – the maximum amount the statute allows in the absence of gross 

negligence or wilful misconduct – for the purposes of estimating a potential penalty. This resulted in a provision of $3,510 million for potential penalties 
under Section 311.

In utilizing the $1,100 per-barrel input, BP took into account that the actual per-barrel penalty a court may impose, or that the Government might 

agree to in settlement, could be lower than $1,100 per barrel if it were determined that such a lower penalty was appropriate based on the factors a court 
is directed to consider in assessing a penalty. In particular, in determining the amount of a civil penalty, Section 311 directs a court to consider a number 
of enumerated factors, including ”the seriousness of the violation or violations, the economic benefit to the violator, if any, resulting from the violation, 
the degree of culpability involved, any other penalty for the same incident, any history of prior violations, the nature, extent, and degree of success of any 
efforts of the violator to minimize or mitigate the effects of the discharge, the economic impact of the penalty on the violator, and any other matters as 
justice may require.” Civil penalties above $1,100 per barrel up to a statutory maximum of $4,300 per barrel of oil discharged would only be imposed if 
gross negligence or wilful misconduct were alleged and subsequently proven. BP expects to seek assessment of a penalty lower than $1,100 per barrel 
based on several of these factors. However, the $1,100 per-barrel rate was utilized for the purposes of calculating a charge after considering and weighing 
all possible outcomes and in light of: (i) BP’s conclusion that it did not act with gross negligence or engage in wilful misconduct; and (ii) the uncertainty as 
to whether a court would assess a penalty below the $1,100 statutory maximum.

On 2 August 2010, the United States Department of Energy and the Flow Rate Technical Group had issued an estimate that 4.9 million barrels 

of oil had flowed from the Macondo well, and 4.05 million barrels had been discharged into the Gulf (the difference being the amount of oil captured by 
vessels on the surface as part of BP’s well containment efforts).

It was and remains BP’s view, that the 2 August 2010 Government estimate and other similar estimates are not reliable estimates because 

they are based on incomplete or inaccurate information, rest in large part on assumptions that have not been validated, and are subject to far greater 
uncertainties than have been acknowledged. As BP has publicly asserted, including at a 22 October 2010 meeting with the staff of the National 
Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, BP believes that the 2 August 2010 discharge estimate and similar estimates are 
overstated by a significant amount, and that the flow rate is potentially in the range of 20–50% lower. If the flow rate is 50% lower than the 2 August 2010 
estimate, then the amount of oil that flowed from the Macondo well would be approximately 2.5 million barrels, and the amount discharged into the Gulf 
would be approximately 1.6 million barrels. If the flow rate is 20% lower than the 2 August 2010 estimate, then the amount of oil that flowed from the 
Macondo well would be approximately 3.9 million barrels and the amount discharged into the Gulf would be approximately 3.1 million barrels, which is not 
materially different from the amount we used for our original estimate at the second quarter of 2010.

BP Annual Report and Form 20-F 2011    233

Financial statementsNotes on financial statements36. Provisions continued
Therefore, for the purposes of calculating a provision for fines and penalties under Section 311 of the Clean Water Act, BP has continued to use an 
estimate of 3.2 million barrels of oil discharged to the Gulf of Mexico as its current best estimate, as defined in paragraphs 36-40 of IAS 37 ‘Provisions, 
contingent liabilities and contingent assets’, of the amount which may be used in calculating the penalty under Section 311 of the Clean Water Act. 
This reflects an estimate of total flow from the well of approximately 4 million barrels, and an estimate of barrels captured by vessels on the surface, 
currently estimated at 811,000 barrels. In utilizing this estimate, BP has taken into consideration not only its own analysis of the flow and discharge issue, 
but also the analyses and conclusions of other parties, including the US government. The estimate of BP and of other parties as to how much oil was 
discharged to the Gulf of Mexico may change, perhaps materially, over time. Changes in estimates as to flow and discharge could affect the amount 
actually assessed for Clean Water Act fines and penalties. The year-end provision continued to be based on a per-barrel penalty of $1,100 for the reasons 
discussed above, including BP’s continued conclusion that it did not act with gross negligence or engage in wilful misconduct.

The amount and timing of these costs will depend upon what is ultimately determined to be the volume of oil spilled and the per-barrel penalty 

rate that is imposed. It is not currently practicable to estimate the timing of expending these costs and the provision has been included within non-current 
liabilities on the balance sheet. No other amounts have been provided as at 31 December 2011 in relation to other potential fines and penalties because it 
is not possible to measure the obligation reliably. Fines and penalties are not covered by the trust fund.

37. Pensions and other post-retirement benefits

Most group companies have pension plans, the forms and benefits of which vary with conditions and practices in the countries concerned. Pension 
benefits may be provided through defined contribution plans (money purchase plans) or defined benefit plans (final salary and other types of plans with 
committed pension payments). For defined contribution plans, retirement benefits are determined by the value of funds arising from contributions paid in 
respect of each employee. For defined benefit plans, retirement benefits are based on such factors as the employees’ pensionable salary and length of 
service. Defined benefit plans may be externally funded or unfunded. The assets of funded plans are generally held in separately administered trusts.

In particular, the primary pension arrangement in the UK is a funded final salary pension plan under which retired employees draw the majority of 
their benefit as an annuity. With effect from 1 April 2010, BP closed its UK plan to new joiners other than some of those joining the North Sea business. 
The plan remains open to ongoing accrual for those employees who had joined BP on or before 31 March 2010. The majority of new joiners in the UK 
have the option to join a defined contribution plan.

In the US, a range of retirement arrangements is provided. This includes a funded final salary pension plan for certain heritage employees and a 

cash balance arrangement for new hires. Retired US employees typically take their pension benefit in the form of a lump sum payment. US employees are 
also eligible to participate in a defined contribution (401k) plan in which employee contributions are matched with company contributions.

The level of contributions to funded defined benefit plans is the amount needed to provide adequate funds to meet pension obligations as they fall 

due. During 2011, contributions of $429 million (2010 $411 million and 2009 $9 million) and $777 million (2010 $694 million and 2009 $795 million) were 
made to the UK plans and US plans respectively. In addition, contributions of $223 million (2010 $188 million and 2009 $204 million) were made to other 
funded defined benefit plans. The aggregate level of contributions in 2012 is expected to be approximately $1,250 million, and includes contributions in all 
countries that we expect to be required to make by law or under contractual agreements as well as an allowance for discretionary funding.

Certain group companies, principally in the US, provide post-retirement healthcare and life insurance benefits to their retired employees and 
dependants. The entitlement to these benefits is usually based on the employee remaining in service until retirement age and completion of a minimum 
period of service.

The obligation and cost of providing pensions and other post-retirement benefits is assessed annually using the projected unit credit method. The 

date of the most recent actuarial review was 31 December 2011. The group’s principal plans are subject to a formal actuarial valuation every three years in 
the UK, with valuations being required more frequently in many other countries. The most recent formal actuarial valuation of the UK pension plans was as 
at 31 December 2008.

The material financial assumptions used for estimating the benefit obligations of the various plans are set out below. The assumptions are reviewed by 

management at the end of each year, and are used to evaluate accrued pension and other post-retirement benefits at 31 December. The same assumptions 
are used to determine pension and other post-retirement benefit expense for the following year, that is, the assumptions at 31 December 2011 are used to 
determine the pension liabilities at that date and the pension expense for 2012.

Our discount rate assumptions are based on third-party AA corporate bond indices and for our largest plans in the UK, US and Germany we use yields 
that reflect the maturity profile of the expected benefit payments. The inflation rate assumptions for our UK and US plans are based on the difference 
between the yields on index-linked and fixed-interest long-term government bonds. In other countries we use either this approach, or the central bank 
inflation target, or advice from the local actuary depending on the information that is available to us. The inflation rate assumptions are used to determine 
the rate of increase for pensions in payment and the rate of increase in deferred pensions where there is such an increase.

Our assumptions for the rate of increase in salaries are based on our inflation rate assumption plus an allowance for expected long-term real salary 
growth. These include allowance for promotion-related salary growth, of between 0.3% and 0.4% depending on country.

In addition to the financial assumptions, we regularly review the demographic and mortality assumptions. The mortality assumptions reflect best 

practice in the countries in which we provide pensions, and have been chosen with regard to the latest available published tables adjusted where appropri-
ate to reflect the experience of the group and an extrapolation of past longevity improvements into the future. BP’s most substantial pension liabilities are 
in the UK, the US and Germany where our mortality assumptions are as follows:

Pension plan assets are generally held in trusts. The primary objective of the trusts is to accumulate pools of assets sufficient to meet the obligations of 
the various plans. The assets of the trusts are invested in a manner consistent with fiduciary obligations and principles that reflect current practices in 
portfolio management.

A significant proportion of the assets are held in equities, owing to a higher expected level of return over the long term with an acceptable level of 

risk. In order to provide reasonable assurance that no single security or type of security has an unwarranted impact on the total portfolio, the investment 
portfolios are highly diversified. The long-term asset allocation policy for the major plans is as follows:

Some of the group’s pension plans use derivative financial instruments as part of their asset mix and to manage the level of risk. The group’s main pen-
sion plans do not invest directly in either securities or property/real estate of the company or of any subsidiary.

Return on asset assumptions reflect the group’s expectations built up by asset class and by plan. The group’s expectation is derived from  

a combination of historical returns over the long term and the forecasts of market professionals. Our assumption for return on equities is based on a  
long-term view, and the size of the resulting equity risk premium over government bond yields is reviewed each year for reasonableness. Our assumption 
for return on bonds reflects the portfolio mix of government fixed-interest, index-linked and corporate bonds.

 a The amounts classified as equities include investments in companies listed on stock exchanges as well as private equity investments which are substantially all unlisted. The market value of private equity 
investments at 31 December 2011 was $4,099 million (2010 $3,348 million and 2009 $2,956 million). The equity return assumption shown above is the weighted average of the assumed returns for listed 
and private equity investments in each fund. Comparative return assumptions for the US pension plans’ equities have been restated to reflect this. Equity return assumptions previously disclosed reflected 
the assumption for listed equities only.

 a The nominal amount of 8% cumulative first preference shares and 9% cumulative second preference shares that can be in issue at any time shall not exceed £10,000,000 for each class of preference 
shares.
 b The nominal value of new shares issued for the employee share plans in 2011 amounted to $162,000. Consideration received relating to the issue of new shares for employee share plans amounted to 
$4 million (2010 $138 million and 2009 $84 million).

Voting on substantive resolutions tabled at a general meeting is on a poll. On a poll, shareholders present in person or by proxy have two votes for every 
£5 in nominal amount of the first and second preference shares held and one vote for every ordinary share held. On a show-of-hands vote on other 
resolutions (procedural matters) at a general meeting, shareholders present in person or by proxy have one vote each.

In the event of the winding up of the company, preference shareholders would be entitled to a sum equal to the capital paid up on the preference 
shares, plus an amount in respect of accrued and unpaid dividends and a premium equal to the higher of (i) 10% of the capital paid up on the preference 
shares and (ii) the excess of the average market price of such shares on the London Stock Exchange during the previous six months over par value.

Share premium account
The balance on the share premium account represents the amounts received in excess of the nominal value of the ordinary and preference shares.

Capital redemption reserve
The balance on the capital redemption reserve represents the aggregate nominal value of all the ordinary shares repurchased and cancelled.

Merger reserve

Treasury shares represent BP shares repurchased and available for re-issue.

Foreign currency translation reserve
The foreign currency translation reserve is used to record exchange differences arising from the translation of the financial statements of foreign 
operations. Upon disposal of foreign operations, the related accumulated exchange differences are recycled to the income statement. This reserve is also 
used to record the effect of hedging net investments in foreign operations. 

Available-for-sale investments
This reserve records the changes in fair value of available-for-sale investments. On disposal or impairment, the cumulative changes in fair value are 
recycled to the income statement.

Cash flow hedges
This reserve records the portion of the gain or loss on a hedging instrument in a cash flow hedge that is determined to be an effective hedge. When the 
hedged transaction occurs, the gain or loss on the hedging instrument is transferred out of equity to either profit or loss or the carrying value of assets, as 
appropriate. If the forecast transaction is no longer expected to occur the gain or loss recognized in equity is transferred to profit or loss.

Share-based payment reserve
This reserve represents cumulative amounts charged to profit in respect of employee share-based payment plans where the scheme has not yet been 
settled by means of an award of shares to an individual.

Profit and loss account
The balance held on this reserve is the accumulated retained profits of the group.

For ease of presentation, options and shares detailed in the tables within this note are stated as UK ordinary share equivalents in US dollars. US 
employees are granted American Depositary Shares (ADSs) or options over the company’s ADSs (one ADS is equivalent to six ordinary shares). The main 
share-based payment plans that existed during the year are detailed below.

Plans for executive directors
For further information on the Executive Directors’ Incentive Plan (EDIP) see the Directors’ remuneration report on pages 139 to 151.

Plans for senior employees
The group operates a number of equity-settled share plans under which share units are granted to its senior leaders and certain other employees. These 
plans typically have a three-year performance or restricted period during which the units accrue net notional dividends which are treated as having been 
reinvested. Leaving employment will normally preclude the conversion of units into shares, but special arrangements apply for participants that leave for 
qualifying reasons. Grants are settled in cash where the regulatory environment prohibits participants to hold BP shares.

Performance unit plans
The number of units granted is related to the level of seniority of employees. The number of units converted to shares is determined by reference to 
performance measures over the three-year performance period. The main performance measure used is BP’s total shareholder return (TSR) compared to 
the other oil majors. Plans included in this category are the Competitive Performance Plan (CPP) and, in part, the Performance Share Plan (PSP).

Restricted share unit plans
Share unit grants under BP’s restricted plans typically take into account the employee’s performance in either the current or the prior year, track record 
of delivery, business and leadership skills and potential. One restricted share unit plan for senior employees, used in special circumstances such as 
recruitment and retention, normally has no performance conditions. Plans included in this category are the Executive Performance Plan (EPP), the 
Restricted Share Plan (RSP), the Deferred Annual Bonus Plan (DAB) and, in part, the Performance Share Plan (PSP).

BP Share Option Plan (BPSOP)
Share options with an exercise price equivalent to the market price of a BP share immediately preceding the date of grant were granted to participants annually 
until 2006. These options are not subject to any performance conditions and are exercisable between the third and tenth anniversaries of the grant date.

BP Plan 2011
Share options with an exercise price equivalent to the market price of a BP share immediately preceding the date of grant were granted to participants in 
2011. These options are not subject to any performance conditions and will be exercisable between the third and tenth anniversaries of the grant date.

Share Value Plan
In 2012, the group will launch a new performance plan known as the Share Value Plan (SVP) which will grant restricted share units with a three-year 
performance period. The number of units granted is dependent on grade and country of operation. The performance measures are grade specific and 
include individual rating, balanced scorecard and TSR criteria. For the 2012 performance year, no further grants will be made under DAB; and from 
1 January 2012, no further grants will be made under CPP, EPP or PSP.

Other plans
For further information on BP’s savings and matching plans, including the BP ShareMatch plans and the BP ShareSave Plan, see page 158.

The group uses the observable market price for ordinary shares at the date of grant to determine the fair value of non-TSR restricted share units.

The group used a Monte Carlo simulation to determine the fair values of the TSR elements of the 2011, 2010 and 2009 CPP and EDIP grants and 

the 2009 PSP grant. In accordance with the plans’ rules, the model simulates BP’s TSR and compares it against its principal strategic competitors over the 
three-year period of the plans. The model takes into account the historical dividends, share price volatilities and covariances of BP and each comparator 
company to produce a predicted distribution of relative share performance. This is applied to the reward criteria to give an expected value of the TSR 
element.

Accounting expense does not necessarily represent the actual value of share-based payments made to recipients, which are determined by the 

remuneration committee according to established criteria.

Employee Share Ownership Plan Trusts (ESOPs)
ESOPs have been established to acquire BP shares to satisfy any awards made to participants under the BP share plans as required. The ESOPs have 
waived their rights to dividends on shares held for future awards and are funded by the group. Until such time as the company’s own shares held by the 
ESOPs vest unconditionally to employees, the amount paid for those shares is shown as a reduction in shareholders’ equity (see Note 39). Assets and 
liabilities of the ESOPs are recognized as assets and liabilities of the group.

At 31 December 2011, the ESOPs held 27,784,503 shares (2010 11,477,253 shares and 2009 18,062,246 shares) for potential future awards, 

which had a market value of $197 million (2010 $82 million and 2009 $174 million).

2009 nil).

Pension contributions
During 2011 one executive director participated in a non-contributory pension plan established for UK employees by a separate trust fund to which 
contributions are made by BP based on actuarial advice. Two US executive directors participated in the US BP Retirement Accumulation Plan during 2011.

Office facilities for former chairmen and deputy chairmen
It is customary for the company to make available to former chairmen and deputy chairmen, who were previously employed executives, the use of office 
and basic secretarial facilities following their retirement. The cost involved in doing so is not significant.

Notes on financial statements42. Remuneration of directors and senior management continued
Senior management, in addition to executive and non-executive directors, includes other senior managers who are members of the executive 
management team.

Short-term employee benefits
In addition to fees paid to the non-executive chairman and non-executive directors, these amounts comprise, for executive directors and senior managers, 
salary and benefits earned during the year, plus cash bonuses awarded for the year. Deferred annual bonus awards, to be settled in shares, are included in 
share-based payments. Short-term employee benefits includes compensation for loss of office of $9 million (2010 $3 million and 2009 $6 million).

Post-retirement benefits
The amounts represent the estimated cost to the group of providing defined benefit pensions and other post-retirement benefits to senior management 
in respect of the current year of service measured in accordance with IAS 19 ‘Employee Benefits’.

Share-based payments
This is the cost to the group of senior management’s participation in share-based payment plans, as measured by the fair value of options and shares 
granted accounted for in accordance with IFRS 2 ‘Share-based Payments’. The main plans in which senior management have participated are the EDIP, 
DAB and RSP. For details of these plans refer to Note 40.

43. Contingent liabilities

Contingent liabilities relating to the Gulf of Mexico oil spill
As a consequence of the Gulf of Mexico oil spill, as described on pages 76 to 79, BP has incurred costs during the year and recognized provisions for 
certain future costs. Further information is provided in Note 2 and Note 36.

BP has provided for its best estimate of amounts expected to be paid from the $20-billion trust fund. This includes certain amounts expected to 

be paid pursuant to the Oil Pollution Act of 1990 (OPA 90) as well as the increased estimate of the cost of individual and business claims as a result of the 
proposed settlement with the PSC announced on 3 March 2012 as described in Note 2 and Note 36. It is not possible, at this time, to measure reliably 
any other items that will be paid from the trust fund, namely any obligation in relation to Natural Resource Damages claims other than the emergency 
and early restoration costs as described in Note 36, and claims asserted in civil litigation including any further litigation through potential opt-outs from the 
proposed settlement agreement, nor is it practicable to estimate their magnitude or possible timing of payment.

Natural resource damages resulting from the oil spill are currently being assessed (see Note 36 for further information). BP and the federal 
and state trustees are collecting extensive data in order to assess the extent of damage to wildlife, shoreline, near shore and deepwater habitats, 
and recreational uses, among other things. Because the affected areas and their uses vary by seasons, we are continuing our work to complete a full 
assessment of the natural resource damages. In addition, as and when early restoration projects are undertaken, these projects could mitigate the total 
damages resulting from the incident. Accordingly, until the size, location and duration of the impact have been fully determined and the effects of early 
restoration projects are fully assessed, or other actions such as potential future settlement discussions occur, it is not possible to obtain a range of 
outcomes or to estimate reliably either the amounts (other than the amounts previously provided for emergency and early restoration projects) or timing 
of the remaining Natural Resource Damages claims.

BP is named as a defendant in approximately 600 civil lawsuits brought by individuals, corporations and governmental entities in US federal and 

state courts resulting from the Gulf of Mexico oil spill. Additional lawsuits are likely to be brought. The lawsuits assert, among others, claims for personal 
injury in connection with the incident itself and the response to it, and wrongful death, commercial or economic injury, securities and shareholder claims, 
breach of contract and violations of statutes. The lawsuits, many of which purport to be class actions, seek various remedies including compensation to 
injured workers and families of deceased workers, recovery for commercial losses and property damage, claims for environmental damage, remediation 
costs, injunctive relief, treble damages and punitive damages. Most of these lawsuits have been consolidated into one of two multi-district litigation 
(MDL) proceedings. On 3 March 2012, BP announced that it had reached a proposed settlement with the Plaintiffs’ Steering Committee (PSC), subject 
to final written agreement and court approvals, to resolve the substantial majority of legitimate economic loss and medical claims stemming from the 
Deepwater Horizon accident and oil spill. The PSC acts on behalf of individual and business plaintiffs in the MDL 2179 and the estimated cost of the 
proposed settlement has been reflected in the financial statements. While BP announced that it had reached a proposed settlement with the PSC, a trial 
of liability issues in the MDL 2179 is, at this time, still expected to go ahead. Damage issues will be scheduled for trial thereafter. Until further fact and 
expert disclosures occur, court rulings clarify the issues in dispute, liability and damage trial activity nears, or other actions such as possible settlements 
occur, it is not possible given these uncertainties to arrive at a range of outcomes or a reliable estimate of the liability other than the estimated cost of the 
proposed settlement with the PSC. See Legal proceedings on pages 160 to 164 for further information.

Therefore, with the exception of the estimated costs of the proposed settlement agreement with the PSC, no amounts have been provided for 
these items as of 31 December 2011. Although these items, which will be paid through the trust fund, have not been provided for at this time, BP‘s full 
obligation under the $20-billion trust fund has been expensed in the income statement, taking account of the time value of money. The aggregate of 
amounts paid and provided for items to be settled from the trust fund currently falls within the amount committed by BP to the trust fund.

For those items not covered by the trust fund it is not possible to measure reliably any obligation in relation to other litigation or potential fines and 

penalties except, subject to certain assumptions detailed in Note 36, for those relating to the Clean Water Act. There are a number of federal and state 
environmental and other provisions of law, other than the Clean Water Act, under which one or more governmental agencies could seek civil fines and 
penalties from BP. For example, a complaint filed by the United States sought to reserve the ability to seek penalties and other relief under a number 
of other laws. Given the large number of claims that may be asserted, it is not possible at this time to determine whether and to what extent any such 
claims would be successful or what penalties or fines would be assessed. Therefore no amounts have been provided for these items.

Under the settlement agreements with Anadarko and MOEX, BP has agreed to indemnify Anadarko and MOEX for certain claims arising from 

the accident (excluding civil, criminal or administrative fines and penalties, claims for punitive damages, and certain other claims). Under the settlement 
agreement entered into with M-I L.L.C. (M-I) (see Legal proceedings on pages 160 to 164), BP agreed to indemnify M-I for certain claims resulting from 
the accident. M-I was contracted by BP to provide specialized drilling mud and mud engineering services for the Macondo well. It is therefore possible 
that BP may face claims under these indemnities, but it is not currently possible to reliably measure any obligation in relation to such claims and therefore 
no amount has been provided as at 31 December 2011.

BP Annual Report and Form 20-F 2011    249

Financial statementsNotes on financial statements43. Contingent liabilities continued

The magnitude and timing of possible obligations in relation to the Gulf of Mexico oil spill are subject to a very high degree of uncertainty as 
described further in Risk factors on pages 59 to 63. Any such possible obligations are therefore contingent liabilities and, at present, it is not 
practicable to estimate their magnitude or possible timing of payment. Certain items are subject to settlement discussions or may be subject to 
settlement discussions in the future. Any settlements which may be reached relating to the Deepwater Horizon accident and oil spill could impact the 
amount and timing of any future payments. Furthermore, other material unanticipated obligations may arise in future in relation to the incident.

Other contingent liabilities
There were contingent liabilities at 31 December 2011 in respect of guarantees and indemnities entered into as part of the ordinary course of the group‘s 
business. No material losses are likely to arise from such contingent liabilities. Further information is included in Note 26.

Lawsuits arising out of the Exxon Valdez oil spill in Prince William Sound, Alaska, in March 1989 were filed against Exxon (now ExxonMobil), 

Alyeska Pipeline Service Company (Alyeska), which operates the oil terminal at Valdez, and the other oil companies that own Alyeska. Alyeska 
initially responded to the spill until the response was taken over by Exxon. BP owns a 46.9% interest (reduced during 2001 from 50% by a sale 
of 3.1% to Phillips) in Alyeska through a subsidiary of BP America Inc. and briefly indirectly owned a further 20% interest in Alyeska following 
BP‘s combination with Atlantic Richfield Company (Atlantic Richfield). Alyeska and its owners have settled all the claims against them under these 
lawsuits. Exxon has indicated that it may file a claim for contribution against Alyeska for a portion of the costs and damages that Exxon has incurred. 
BP will defend any such claims vigorously. It is not possible to estimate any financial effect.

In the normal course of the group‘s business, legal proceedings are pending or may be brought against BP group entities arising out 
of current and past operations, including matters related to commercial disputes, product liability, antitrust, premises-liability claims, general 
environmental claims and allegations of exposures of third parties to toxic substances, such as lead pigment in paint, asbestos and other chemicals. 
BP believes that the impact of these legal proceedings on the group‘s results of operations, liquidity or financial position will not be material.

With respect to lead pigment in paint in particular, Atlantic Richfield, a subsidiary of BP, has been named as a co-defendant in numerous 

lawsuits brought in the US alleging injury to persons and property. Although it is not possible to predict the outcome of the legal proceedings, 
Atlantic Richfield believes it has valid defences that render the incurrence of a liability remote; however, the amounts claimed and the costs of 
implementing the remedies sought in the various cases could be substantial. The majority of the lawsuits have been abandoned or dismissed against 
Atlantic Richfield. No lawsuit against Atlantic Richfield has been settled nor has Atlantic Richfield been subject to a final adverse judgment in any 
proceeding. Atlantic Richfield intends to defend such actions vigorously.

The group files income tax returns in many jurisdictions throughout the world. Various tax authorities are currently examining the group‘s 

income tax returns. Tax returns contain matters that could be subject to differing interpretations of applicable tax laws and regulations and the 
resolution of tax positions through negotiations with relevant tax authorities, or through litigation, can take several years to complete. While it is 
difficult to predict the ultimate outcome in some cases, the group does not anticipate that there will be any material impact upon the group‘s results 
of operations, financial position or liquidity.

The group is subject to numerous national and local environmental laws and regulations concerning its products, operations and other 

activities. These laws and regulations may require the group to take future action to remediate the effects on the environment of prior disposal or 
release of chemicals or petroleum substances by the group or other parties. Such contingencies may exist for various sites including refineries, 
chemical plants, oilfields, service stations, terminals and waste disposal sites. In addition, the group may have obligations relating to prior asset sales 
or closed facilities. The ultimate requirement for remediation and its cost are inherently difficult to estimate. However, the estimated cost of known 
environmental obligations has been provided in these accounts in accordance with the group‘s accounting policies. While the amounts of future 
costs could be significant and could be material to the group‘s results of operations in the period in which they are recognized, it is not practical to 
estimate the amounts involved. BP does not expect these costs to have a material effect on the group‘s financial position or liquidity.

The group also has obligations to decommission oil and natural gas production facilities and related pipelines. Provision is made for the 

estimated costs of these activities, however there is uncertainty regarding both the amount and timing of these costs, given the long-term nature 
of these obligations. BP believes that the impact of any reasonably foreseeable changes to these provisions on the group‘s results of operations, 
financial position or liquidity will not be material.

The group generally restricts its purchase of insurance to situations where this is required for legal or contractual reasons. This is because 

external insurance is not considered an economic means of financing losses for the group. Losses will therefore be borne as they arise rather than 
being spread over time through insurance premiums with attendant transaction costs. The position is reviewed periodically.

44. Capital commitments

Authorized future capital expenditure for property, plant and equipment by group companies for which contracts had been placed at 31 December 2011 
amounted to $12,517 million (2010 $11,279 million). In addition, at 31 December 2011, the group had contracts in place for future capital expenditure 
relating to investments in jointly controlled entities of $296 million (2010 $437 million) and investments in associates of $36 million (2010 $80 million). 

BP’s share of capital commitments of jointly controlled entities amounted to $1,244 million (2010 $1,117 million).

Notes on financial statementsSupplementary information on oil and natural gas (unaudited)

The regional analysis presented below is on a continent basis, with separate disclosure for countries that contain 15% or more of the total proved 
reserves (for subsidiaries plus equity-accounted entities), in accordance with SEC and FASB requirements.

Oil and gas reserves – certain definitions
Unless the context indicates otherwise, the following terms have the meanings shown below:

Proved oil and gas reserves
Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable 
certainty to be economically producible – from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, 
and government regulations – prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is 
reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must 
have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.
(i) 

The area of the reservoir considered as proved includes:
(A)  The area identified by drilling and limited by fluid contacts, if any; and
(B) 

 Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain 
economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) 

(iii) 

(iv) 

(v) 

 In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well 
penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.
 Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas 
cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data 
and reliable technology establish the higher contact with reasonable certainty.
 Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) 
are included in the proved classification when:
(A) 

 Successful testing by a pilot project in an area of the reservoir with properties no more favourable than in the reservoir as a whole, the 
operation of an installed programme in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the 
reasonable certainty of the engineering analysis on which the project or programme was based; and
 The project has been approved for development by all necessary parties and entities, including governmental entities.

(B) 
 Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the 
average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic 
average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding 
escalations based upon future conditions.

Undeveloped oil and gas reserves
Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing 
wells where a relatively major expenditure is required for recompletion.
(i) 

 Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production 
when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.
 Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are 
scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.
 Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other 
improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an 
analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.

(ii) 

(iii) 

Developed oil and gas reserves
Developed oil and gas reserves are reserves of any category that can be expected to be recovered:
(i) 

 Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor 
compared to the cost of a new well; and
 Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not 
involving a well.

(ii) 

For details on BP’s proved reserves and production compliance and governance processes, see pages 90 to 91.

 a Crude oil includes NGLs and condensate. Proved reserves exclude royalties due to others, whether payable in cash or in kind, where the royalty owner has a direct interest in the underlying production and 
the option and ability to make lifting and sales arrangements independently.
 b Excludes NGLs from processing plants in which an interest is held of 28 thousand barrels per day.
 c Includes 616 million barrels of NGLs. Also includes 20 million barrels of crude oil in respect of the 30% minority interest in BP Trinidad and Tobago LLC.
 d Includes 19 million barrels of NGLs. Also includes 310 million barrels of crude oil in respect of the 7.37% minority interest in TNK-BP.
 e Proved reserves in the Prudhoe Bay field in Alaska include an estimated 82 million barrels upon which a net profits royalty will be payable over the life of the field under the terms of the BP Prudhoe Bay 
Royalty Trust.
 f Volumes of equity-accounted entities include volumes of equity-accounted investments of those entities.
 g Total proved liquid reserves held as part of our equity interest in TNK-BP is 4,305 million barrels, comprising 95 million barrels in Venezuela, one million barrels in Vietnam and 4,209 million barrels in Rus-
sia. In 2011, BP aligned its reporting with TNK-BP by moving to a life of field reporting basis. Reasonable certainty of licence renewals is demonstrated by evidence of Russian subsoil law, track record of 
renewals within the industry and track record of success in obtaining renewals by TNK-BP. This has resulted in an increase in proved liquid reserves of 221 million barrels.

 a Proved reserves exclude royalties due to others, whether payable in cash or in kind, where the royalty owner has a direct interest in the underlying production and the option and ability to make lifting and 
sales arrangements independently.
 b Excludes NGLs from processing plants in which an interest is held of 28 thousand barrels of oil equivalent per day.
 c Includes 616 million barrels of NGLs. Also includes 496 million barrels of oil equivalent in respect of the 30% minority interest in BP Trinidad and Tobago LLC.
 d Includes 19 million barrels of NGLs. Also includes 340 million barrels of oil equivalent in respect of the minority interest in TNK-BP.
 e Proved reserves in the Prudhoe Bay field in Alaska include an estimated 82 million barrels of oil equivalent upon which a net profits royalty will be payable.
  f Includes 34 million barrels of oil equivalent of natural gas consumed in operations, 27 million barrels of oil equivalent in subsidiaries, seven million barrels of oil equivalent in equity-accounted entities and 
excludes two million barrels of oil equivalent of produced non-hydrocarbon components which meet regulatory requirements for sales.
 g Volumes of equity-accounted entities include volumes of equity-accounted investments of those entities.
 h Total proved reserves held as part of our equity interest in TNK-BP is 4,802 million barrels of oil equivalent, comprising 100 million barrels of oil equivalent in Venezuela, 14 million barrels of oil equivalent in  
Vietnam and 4,688 million barrels of oil equivalent in Russia. In 2011, BP aligned its reporting with TNK-BP by moving to a life of field reporting basis. Reasonable certainty of licence renewals is demonstrated 
by evidence of Russian subsoil law, track record of renewals within the industry and track record of success in obtaining renewals by TNK-BP. This has resulted in an increase in proved reserves of 
253 million barrels of oil equivalent.

276    BP Annual Report and Form 20-F 2011

Supplementary information on oil and natural gas (unaudited)Standardized measure of discounted future net cash flows and 
changes therein relating to proved oil and gas reserves

The following tables set out the standardized measure of discounted future net cash flows, and changes therein, relating to crude oil and natural gas 
production from the group’s estimated proved reserves. This information is prepared in compliance with FASB Oil and Gas Disclosures requirements.

Future net cash flows have been prepared on the basis of certain assumptions which may or may not be realized. These include the timing 

of future production, the estimation of crude oil and natural gas reserves and the application of average crude oil and natural gas prices and exchange 
rates from the previous 12 months. Furthermore, both proved reserves estimates and production forecasts are subject to revision as further technical 
information becomes available and economic conditions change. BP cautions against relying on the information presented because of the highly arbitrary 
nature of the assumptions on which it is based and its lack of comparability with the historical cost information presented in the financial statements.

 a Production excludes royalties due to others, whether payable in cash or in kind, where the royalty owner has a direct interest in the underlying production and the option and ability to make lifting and 
sales arrangements independently.
 b Crude oil includes natural gas liquids and condensate.
 c Natural gas production excludes gas consumed in operations.

Productive oil and gas wells and acreage
The following tables show the number of gross and net productive oil and natural gas wells and total gross and net developed and undeveloped oil and 
natural gas acreage in which the group and its equity-accounted entities had interests as at 31 December 2011. A ‘gross’ well or acre is one in which a 
whole or fractional working interest is owned, while the number of ‘net’ wells or acres is the sum of the whole or fractional working interests in gross wells or 
acres. Productive wells are producing wells and wells capable of production. Developed acreage is the acreage within the boundary of a field, on which 
development wells have been drilled, which could produce the reserves; while undeveloped acres are those on which wells have not been drilled or 
completed to a point that would permit the production of commercial quantities, whether or not such acres contain proved reserves.

Net oil and gas wells completed or abandoned
The following table shows the number of net productive and dry exploratory and development oil and natural gas wells completed or abandoned in the 
years indicated by the group and its equity-accounted entities. Productive wells include wells in which hydrocarbons were encountered and the drilling or 
completion of which, in the case of exploratory wells, has been suspended pending further drilling or evaluation. A dry well is one found to be incapable of 
producing hydrocarbons in sufficient quantities to justify completion.

282    BP Annual Report and Form 20-F 2011

Parent company financial statements of BP p.l.c.

Independent auditor’s report to the members of BP p.l.c. 

We have audited the parent company financial statements of BP p.l.c. for the year ended 31 December 2011 which comprise the company balance sheet, 
the company cash flow statement, the company statement of total recognized gains and losses and the related notes 1 to 13. The financial reporting 
framework that has been applied in their preparation is applicable law and United Kingdom accounting standards (United Kingdom generally accepted 
accounting practice).

This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit 

work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor’s report 
and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the 
company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

Respective responsibilities of directors and auditors
As explained more fully in the Statement of directors’ responsibilities set out on page 174, the directors are responsible for the preparation of the parent 
company financial statements and for being satisfied that they give a true and fair view. Our responsibility is to audit the parent company financial 
statements in accordance with applicable law and International Standards on Auditing (UK and Ireland). Those standards require us to comply with the 
Auditing Practices Board’s Ethical Standards for Auditors.

Scope of the audit of the financial statements
An audit involves obtaining evidence about the amounts and disclosures in the financial statements sufficient to give reasonable assurance that the 
financial statements are free from material misstatement, whether caused by fraud or error. This includes an assessment of: whether the accounting 
policies are appropriate to the parent company’s circumstances and have been consistently applied and adequately disclosed; the reasonableness of 
significant accounting estimates made by the directors; and the overall presentation of the financial statements.

Opinion on financial statements
In our opinion the parent company financial statements:
•	 give a true and fair view of the state of the company’s affairs as at 31 December 2011;
•	 have been properly prepared in accordance with United Kingdom generally accepted accounting practice; and
•	 have been prepared in accordance with the requirements of the Companies Act 2006.

Opinion on other matters prescribed by the Companies Act 2006
In our opinion:
•	 the part of the Directors’ remuneration report to be audited has been properly prepared in accordance with the Companies Act 2006; and
•	 the information given in the Directors’ Report for the financial year for which the parent company financial statements are prepared is consistent with 

the parent company financial statements.

Matters on which we are required to report by exception
We have nothing to report in respect of the following matters where the Companies Act 2006 requires us to report to you if, in our opinion:
•	 adequate accounting records have not been kept by the parent company, or returns adequate for our audit have not been received from branches not 

visited by us; or

•	 the parent company financial statements and the part of the Directors’ remuneration report to be audited are not in agreement with the accounting 

records and returns; or

•	 certain disclosures of directors’ remuneration specified by law are not made; or
•	 we have not received all the information and explanations we require for our audit.

Other matter
We have reported separately on the consolidated financial statements of BP p.l.c. for the year ended 31 December 2011. That report includes an 
emphasis of matter on the significant uncertainty over provisions and contingencies related to the Gulf of Mexico oil spill.

for and on behalf of Ernst & Young LLP, Statutory Auditor

The maintenance and integrity of the BP p.l.c. website are the responsibility of the directors; the work carried out by the auditors does not involve 
consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have occurred to the financial statements 
since they were initially presented on the website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements 
may differ from legislation in other jurisdictions.

Notes on financial statements

1. Accounting policies

Accounting standards
These financial statements are prepared in accordance with applicable UK accounting standards.

Accounting convention
The financial statements are prepared under the historical cost convention.

Foreign currency transactions
Functional currency is the currency of the primary economic environment in which an entity operates and is normally the currency in which the entity 
primarily generates and expends cash. Transactions in foreign currencies are initially recorded in the functional currency by applying the rate of exchange 
ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated into the functional currency at the 
rate of exchange ruling at the balance sheet date. Any resulting exchange differences are included in profit for the year. Exchange adjustments arising 
when the opening net assets and the profits for the year retained by non-US dollar functional currency branches are translated into US dollars are taken to 
a separate component of equity and reported in the statement of total recognized gains and losses.

Investments
Investments in subsidiaries and associated undertakings are recorded at cost. The company assesses investments for impairment whenever events 
or changes in circumstances indicate that the carrying value of an investment may not be recoverable. If any such indication of impairment exists, the 
company makes an estimate of its recoverable amount. Where the carrying amount of an investment exceeds its recoverable amount, the investment is 
considered impaired and is written down to its recoverable amount.

Share-based payments
Equity-settled transactions
The cost of equity-settled transactions with employees is measured by reference to the fair value at the date at which equity instruments are granted 
and is recognized as an expense over the vesting period, which ends on the date on which the relevant employees become fully entitled to the award. 
Fair value is determined by using an appropriate valuation model. In valuing equity-settled transactions, no account is taken of any vesting conditions, 
other than conditions linked to the price of the shares of the company (market conditions). Non-vesting conditions, such as the condition that employees 
contribute to a savings-related plan, are taken into account in the grant-date fair value, and failure to meet a non-vesting condition is treated as a 
cancellation, where this is within the control of the employee.

No expense is recognized for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition, which 

are treated as vesting irrespective of whether or not the market condition is satisfied, provided that all other performance conditions are satisfied.

At each balance sheet date before vesting, the cumulative expense is calculated, representing the extent to which the vesting period has expired 

and management’s best estimate of the achievement or otherwise of non-market conditions and the number of equity instruments that will ultimately 
vest or, in the case of an instrument subject to a market condition, be treated as vesting as described above. The movement in cumulative expense since 
the previous balance sheet date is recognized in the income statement, with a corresponding entry in equity.

When the terms of an equity-settled award are modified or a new award is designated as replacing a cancelled or settled award, the cost based on 

the original award terms continues to be recognized over the original vesting period. In addition, an expense is recognized over the remainder of the new 
vesting period for the incremental fair value of any modification, based on the difference between the fair value of the original award and the fair value of 
the modified award, both as measured on the date of the modification. No reduction is recognized if this difference is negative.

When an equity-settled award is cancelled, it is treated as if it had vested on the date of cancellation and any cost not yet recognized in the income 

statement for the award is expensed immediately.

Cash-settled transactions
The cost of cash-settled transactions is measured at fair value and recognized as an expense over the vesting period, with a corresponding liability 
recognized on the balance sheet.

Pensions
The cost of providing benefits under the defined benefit plans is determined separately for each plan using the projected unit credit method, which 
attributes entitlement to benefits to the current period (to determine current service cost) and to the current and prior periods (to determine the present 
value of the defined benefit obligation). Past service costs are recognized immediately when the company becomes committed to a change in pension 
plan design. When a settlement (eliminating all obligations for benefits already accrued) or a curtailment (reducing future obligations as a result of a material 
reduction in the scheme membership or a reduction in future entitlement) occurs, the obligation and related plan assets are remeasured using current 
actuarial assumptions and the resultant gain or loss is recognized in the income statement during the period in which the settlement or curtailment occurs.

The interest element of the defined benefit cost represents the change in present value of scheme obligations resulting from the passage of 

time, and is determined by applying the discount rate to the opening present value of the benefit obligation, taking into account material changes in the 
obligation during the year. The expected return on plan assets is based on an assessment made at the beginning of the year of long-term market returns 
on plan assets, adjusted for the forecasts of contributions received and benefits paid during the year. The difference between the expected return on plan 
assets and the interest cost is recognized in the income statement as other finance income or expense.

Actuarial gains and losses are recognized in full within the statement of total recognized gains and losses in the year in which they occur.
The defined benefit pension plan surplus or deficit in the balance sheet comprises the total for each plan of the present value of the defined benefit 

obligation (using a discount rate based on high quality corporate bonds), less the fair value of plan assets out of which the obligations are to be settled 
directly. Fair value is based on market price information and, in the case of quoted securities, is the published bid price. The surplus or deficit, net of 
taxation thereon, is presented separately above the total for net assets on the face of the balance sheet.

Deferred taxation
Deferred tax is recognized in respect of all timing differences that have originated but not reversed at the balance sheet date where transactions or events 
have occurred at that date that will result in an obligation to pay more, or a right to pay less, tax in the future.

Deferred tax assets are recognized only to the extent that it is considered more likely than not that there will be suitable taxable profits from which 

the underlying timing differences can be deducted.

Deferred tax is measured on an undiscounted basis at the tax rates that are expected to apply in the periods in which timing differences reverse, 

based on tax rates and laws enacted or substantively enacted at the balance sheet date.

Use of estimates
The preparation of accounts in conformity with generally accepted accounting practice requires management to make estimates and assumptions that 
affect the reported amounts of assets and liabilities at the date of the accounts and the reported amounts of revenues and expenses during the reporting 
period. Actual outcomes could differ from these estimates.

At 31 December 2011, deferred tax assets of $559 million on pensions (2010 nil) and $91 million on other timing differences (2010 nil) were not recognized 
as it is not considered more likely than not that suitable taxable profits will be available in the company from which the future reversal of the underlying 
timing differences can be deducted. It is anticipated that the reversal of these timing differences will benefit other group companies in the future.

The primary pension arrangement in the UK is a funded final salary pension plan under which retired employees draw the majority of their benefit as an 
annuity. With effect from 1 April 2010, BP closed its UK plan to new joiners other than some of those joining the North Sea business. The plan remains 
open to ongoing accrual for those employees who joined BP on or before 31 March 2010. The majority of new joiners have the option to join a defined 
contribution plan.

The obligation and cost of providing the pension benefits is assessed annually using the projected unit credit method. The date of the most recent 
actuarial review was 31 December 2011. The principal plans are subject to a formal actuarial valuation every three years in the UK. The most recent formal 
actuarial valuation of the main UK pension plan was as at 31 December 2008.

The material financial assumptions used for estimating the benefit obligations of the plans are set out below. The assumptions used to evaluate 

accrued pension at 31 December in any year are used to determine pension expense for the following year, that is, the assumptions at 31 December 
2011 are used to determine the pension liabilities at that date and the pension cost for 2012.

Our discount rate assumption is based on third-party AA corporate bond indices and we use yields that reflect the maturity profile of the expected benefit 
payments. The inflation rate assumption is based on the difference between the yields on index-linked and fixed-interest long-term government bonds. 
The inflation rate assumption is used to determine the rate of increase for pensions in payment and the rate of increase in deferred pensions.

Our assumption for the rate of increase in salaries is based on our inflation rate assumption plus an allowance for expected long-term real salary 

growth. This includes allowance for promotion-related salary growth of 0.4%.

In addition to the financial assumptions, we regularly review the demographic and mortality assumptions. The mortality assumptions reflect best 
practice in the UK, and have been chosen with regard to the latest available published tables adjusted where appropriate to reflect the experience of the 
group and an extrapolation of past longevity improvements into the future.

Mortality assumptions
Life expectancy at age 60 for a male currently aged 60
Life expectancy at age 60 for a male currently aged 40
Life expectancy at age 60 for a female currently aged 60

On 31 March 2011, the Burmah Castrol Pension Fund was merged into the BP Pension Fund. As at that date the assets of the Burmah Castrol Pension 
Fund were transferred to the BP Pension Fund, and in return the BP Pension Fund will provide the pension benefits which would otherwise have been 
provided under the Burmah Castrol Pension Fund. There was no change to the benefits provided to members of either fund as a result of the merger.

In addition, the obligation to provide benefits under an unfunded pension plan operated by Lubricants UK Limited (LUL) was transferred to BP p.l.c. 

on 31 March 2011. After this date the benefits previously provided under the LUL plan will be provided through an unfunded pension plan operated by 
BP p.l.c.

In each case these transfers were effected at the market value of the pension assets and liabilities as at the date of transfer. As a consequence of 
the transfers, the pension plan asset amount of the BP Pension Fund, which is reflected in the accounts of BP p.l.c., was increased by $1,743 million and 
the pension liability was increased by $1,671 million.

 a The nominal amount of 8% cumulative first preference shares and 9% cumulative second preference shares that can be in issue at any time shall not exceed £10,000,000 for each class of 
preference shares.
 b The nominal value of new shares issued for the employee share plans in 2011 amounted to $162,000. Consideration received relating to the issue of new shares for employee share plans amounted to 
$4 million (2010 $138 million).

Voting on substantive resolutions tabled at a general meeting is on a poll. On a poll, shareholders present in person or by proxy have two votes for every 
£5 in nominal amount of the first and second preference shares held and one vote for every ordinary share held. On a show-of-hands vote on other 
resolutions (procedural matters) at a general meeting, shareholders present in person or by proxy have one vote each.

In the event of the winding up of the company, preference shareholders would be entitled to a sum equal to the capital paid up on the preference 

shares plus an amount in respect of accrued and unpaid dividends and a premium equal to the higher of (i) 10% of the capital paid up on the preference 
shares and (ii) the excess of the average market price of such shares on the London Stock Exchange during the previous six months over par value.

For ease of presentation, options and shares detailed in the tables within this note are stated as UK ordinary share equivalents in US dollars. US 
employees are granted American Depositary Shares (ADSs) or options over the company’s ADSs (one ADS is equivalent to six ordinary shares). The main 
share-based payment plans that existed during the year are detailed below.

Plans for executive directors
For further information on the Executive Directors’ Incentive Plan (EDIP) see the Directors’ remuneration report on pages 139 to 151.

Plans for senior employees
The group operates a number of equity-settled share plans under which share units are granted to its senior leaders and certain other employees. These 
plans typically have a three-year performance or restricted period during which the units accrue net notional dividends which are treated as having been 
reinvested. Leaving employment will normally preclude the conversion of units into shares, but special arrangements apply for participants that leave for 
qualifying reasons. Grants are settled in cash where the regulatory environment prohibits participants to hold BP shares.

Performance unit plans
The number of units granted is related to the level of seniority of employees. The number of units converted to shares is determined by reference to 
performance measures over the three-year performance period. The main performance measure used is BP’s total shareholder return (TSR) compared to 
the other oil majors. Plans included in this category are the Competitive Performance Plan (CPP), and, in part, the Performance Share Plan (PSP).

11. Share-based payments continued
Restricted share unit plans
Share unit grants under BP’s restricted plans typically take into account the employee’s performance in either the current or the prior year, track record 
of delivery, business and leadership skills and potential. One restricted share unit plan for senior employees, used in special circumstances such as 
recruitment and retention, normally has no performance conditions. Plans included in this category are the Executive Performance Plan (EPP), the 
Restricted Share Plan (RSP), the Deferred Annual Bonus Plan (DAB) and, in part, the Performance Share Plan (PSP).

BP Share Option Plan (BPSOP)
Share options with an exercise price equivalent to the market price of a BP share immediately preceding the date of grant were granted to participants 
annually until 2006. These options are not subject to any performance conditions and are exercisable between the third and tenth anniversaries of the 
grant date.

BP Plan 2011
Share options with an exercise price equivalent to the market price of a BP share immediately preceding the date of grant were granted to participants in 
2011. These options are not subject to any performance conditions and will be exercisable between the third and tenth anniversaries of the grant date.

Share Value Plan
In 2012, the group will launch a new performance plan known as the Share Value Plan (SVP) which will grant restricted share units with a three-year 
performance period. The number of units granted is dependent on grade and country of operation. The performance measures are grade specific and 
include: individual rating, balanced scorecard and TSR criteria. For the 2012 performance year, no further grants will be made under DAB. From 1 January 
2012, no further grants will be made under CPP, EPP or PSP.

Other plans
For further information on BP’s savings and matching plans, including the BP ShareMatch plans and the BP ShareSave Plan, see page 158.

The group uses the observable market price for ordinary shares at the date of grant to determine the fair value of non-TSR restricted share units.

The group used a Monte Carlo simulation to determine the fair values of the TSR elements of the 2011, 2010 and 2009 CPP and EDIP grants and 

the 2009 PSP grant. In accordance with the plans’ rules, the model simulates BP’s TSR and compares it against its principal strategic competitors over the 
three-year period of the plans. The model takes into account the historical dividends, share price volatilities and covariances of BP and each comparator 
company to produce a predicted distribution of relative share performance. This is applied to the reward criteria to give an expected value of the TSR 
element.

Accounting expense does not necessarily represent the actual value of share-based payments made to recipients, which are determined by the 

remuneration committee according to established criteria.

Employee Share Ownership Plan Trusts (ESOPs)
ESOPs have been established to acquire BP shares to satisfy any awards made to participants under the BP share plans as required. The ESOPs have 
waived their rights to dividends on shares held for future awards and are funded by the group. Until such time as the company’s own shares held by the 
ESOPs vest unconditionally to employees, the amount paid for those shares is shown as a reduction in shareholders’ equity (see Note 8). Assets and 
liabilities of the ESOPs are recognized as assets and liabilities of the group.

At 31 December 2011 the ESOPs held 27,784,503 shares (2010 11,477,253 shares and 2009 18,062,246 shares) for potential future awards, 

which had a market value of $197 million (2010 $82 million and 2009 $174 million).

12. Auditor’s remuneration

Fees payable to the company’s auditors for the audit of the company’s accounts were $15 million (2010 $17 million).

Remuneration receivable by the company’s auditors for the supply of other services to the company is not presented in the parent company 

financial statements as this information is provided in the consolidated financial statements.

Emoluments
These amounts comprise fees paid to the non-executive chairman and the non-executive directors and, for executive directors, salary and benefits earned 
during the relevant financial year, plus bonuses awarded for the year. There was no compensation for loss of office in 2011 (2010 $3 million and 2009 nil).

Pension contributions
During 2011, one executive director participated in a non-contributory pension scheme established for UK staff by a separate trust fund to which 
contributions are made by BP based on actuarial advice. Two US executive directors participated in the US BP Retirement Accumulation Plan during 2011.

Office facilities for former chairmen and deputy chairmen
It is customary for the company to make available to former chairmen and deputy chairmen, who were previously employed executives, the use of office 
and basic secretarial facilities following their retirement. The cost involved in doing so is not significant.

Further information
Full details of individual directors’ remuneration are given in the directors’ remuneration report on pages 139 to 151.
