NATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15

Chairman’s statement 
It’s been a challenging year for the energy sector. Energy policies in the UK and 
US have continued to evolve against a backdrop of political uncertainty, seeking 
an acceptable balance between affordability to consumers, security of supply 
and sustainability considerations.

In focus: 

The Board is proposing 
a recommended  
full-year dividend of

42.87p

(2013/14: 42.03p)

In the UK, we saw debate around the cost of living 
lead to a sharper focus on the costs of energy and 
the competitiveness of energy markets. This focus 
has included an Energy and Climate Change Select 
Committee inquiry into energy network costs, as well 
as an investigation by the Competition and Markets 
Authority into the supply and acquisition of energy 
in Great Britain. 

In the UK, Electricity Market Reform (EMR) was 
implemented successfully, and we saw developments 
in significant interconnector projects (see page 27). 
In the US, there were mid-term US congressional 
and gubernatorial elections and debate continued on 
essential infrastructure, resilience and sustainability. 

Transparency
In January we announced our decision to stop 
publishing formal Interim Management Statements 
(IMSs), following the changes in legislation that 
removed this requirement. Mandatory requirements 
to publish information can frequently provide an 
unnecessary focus on matters of little relevance 
to a long-term business such as National Grid. 

Alongside our major announcements at the half year 
and full year we will continue to provide updates 
covering market and Company developments. 

We also continue to provide commentary on both 
our IFRS reported results and underlying economic 
(regulatory) performance, including reconciliations 
between the key metrics for both results. To help 
explain this more fully, we have increased the 
commentary on our regulatory performance on 
page 23, and have included further analysis of our 
regulatory performance by segment on page 100. 
We support the development of an accounting 
standard for rate-regulated activities, which would 
reduce the need for additional explanations of our 
results, and submitted a response to the IASB’s 
project in January this year.

Dividend
The Board has recommended an increase in the final 
dividend to 28.16 pence per ordinary share ($2.1866 
per American Depositary Share). If approved, this 
will bring the full-year dividend to 42.87 pence per 
ordinary share ($3.3584 per American Depositary 
Share), an increase of 2.0% over the 42.03 pence per 
ordinary share in respect of the financial year ending 
31 March 2014.

In August 2014 we began a share buyback 
programme designed to operate alongside our scrip 
dividend option, which we offered for the interim 
dividend and will offer again for the full-year dividend. 
The buyback programme, which operates under 
authorities granted at our 2014 AGM, is designed to 
balance shareholders’ appetite for the scrip dividend 
option with our desire to operate an efficient balance 
sheet with appropriate leverage.

Effective governance 
In July 2014, John Pettigrew, who joined the Board 
in April 2014, became Executive Director, UK and 
Nick Winser and Maria Richter both stepped down 
from the Board.

Strategic ReportAs you can read on page 17, we are adding new 
KPIs to our reporting, so we can more fully reflect 
the issues that really matter to the Company and 
our stakeholders. For our 2014/15 Report, we have 
included workforce diversity as a new KPI and you 
can read more about our approach to this on pages 
18 and 19, as well as progress in relation to our 
Board diversity policy on page 58. 

You can find more information about our approach 
to being a responsible business, including our 
Total Contribution Report, on our website. 

Looking ahead
We will face both opportunities and challenges over 
the coming year. For example, in the UK Ofgem 
has concluded its Integrated Transmission Planning 
and Regulation project. As part of this, the System 
Operator is expected to undertake a number of 
new advisory roles. We have a long track record in 
successfully managing potential conflicts of interest 
from our System Operator role and will work closely 
with Ofgem to make sure this continues. 

In the US we expect to file important applications 
for new rate plans – you can read more about 
this on page 169. We will continue to work with 
policymakers, customers, and stakeholders to 
transform the energy industry through initiatives 
in Massachusetts, New York, and Rhode Island 
(see pages 33 to 35). 

We must adapt to developments in corporate 
governance requirements. For example, the 
updated UK Corporate Governance Code enhances 
the quality of information investors can expect to 
receive about the long-term health and strategy of 
listed companies, and encourages companies to 
be more transparent about risk management and 
internal control.

Finally, I am confident that our people will continue 
to help make National Grid a company we can all be 
proud of and I thank all our employees for their hard 
work and commitment to our success.

Sir Peter Gershon

Philip Aiken stepped down from the Board in February 
2015 before his appointment as Balfour Beatty’s new 
Chairman. He was a National Grid Non-executive 
Director for six years and played an important role in 
chairing our Safety, Environment and Health Committee. 
Following Philip’s departure, Paul Golby was 
appointed as chairman of the Safety, Environment 
and Health Committee, as well as a member of the 
Audit Committee. Paul remains a member of the 
Nominations and Remuneration Committees. 

Tom King stepped down from the Board and left 
the Company on 31 March 2015. He was succeeded 
by Dean Seavers, who joined the Company in 
December 2014 and, following a thorough handover, 
joined the Board as Executive Director, US with 
effect from 1 April 2015.

John and Dean’s appointments bring fresh 
perspective, experience and challenge to our Board. 
Dean joined us after a career that has included 
business leadership roles of major divisions within 
GE, United Technologies and Tyco. In particular, he 
has led major change and performance improvement 
programmes that have improved operational 
efficiency and customer satisfaction – important 
priorities for our US business.

I would like to thank Nick, Tom, Philip and Maria for 
their commitment to the Board and the very valuable 
contribution they have made.

National Grid’s UK regulated entities appointed 
Catherine Bell and Clive Elphick as Non-executive 
Directors with effect from 1 April 2014. The 
appointment of two Non-executive Directors is a new 
requirement promoted by Ofgem, which has termed 
the appointments Sufficiently Independent Directors. 
The arrangements are designed to enhance the 
financial ring-fencing conditions that already exist 
in the companies’ licences. 

Responsible business
At National Grid, we believe that what we do and 
how we do it are equally important. In July 2014, 
National Grid was named Responsible Business of 
the Year 2014 by Business in the Community (BITC). 
To win this award we had to demonstrate how we 
operate responsibly in everything we do, and how 
we are improving the outcomes for society through 
our work. 

I was delighted that the judging panel commended 
our long-term vision based on trust and connectivity. 
They noted our foresight in using technology and 
innovation to develop solutions that protect our 
employees, customers and wider society; and 
recognised our appetite to inspire others. 

In the UK, we are in discussions with the Living 
Wage Foundation about the opportunity to become 
a fully accredited Living Wage employer. We can 
confirm that all our UK employees fulfil the criteria 
for accreditation. We are also working through the 
Living Wage Charter to understand the impact it 
would have on our supply chain, including the 
companies our suppliers use as sub-contractors, 
should we decide to adopt it.

Strategic ReportNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Chief Executive’s review 
I’m really proud of our performance this year. Overall, our businesses in both 
the UK and US achieved a strong operating performance.

In focus: 

Employee  
engagement score

75%

(2013/14: 71%)

In the UK, there has been a lot of public focus 
on how secure and reliable our energy supply is, 
particularly on tighter margins between electricity 
supply and demand in the winter. Despite tighter 
margins than previous years, we were able to 
operate the system without calling upon our 
additional reserve. This was because of stronger 
than expected plant availability, mild weather, 
healthy wind output and consistent interconnector 
imports from France and the Netherlands. 

We also tendered the two new balancing services 
for additional reserves of supply. Although these 
additional reserves were not used, this was a 
sensible precaution in case of colder weather 
or a series of unexpected plant shutdowns.

In the US, we saw an extremely harsh and 
prolonged period of plunging temperatures and 
record levels of snowfall in parts of New England, 
particularly in February and March. Again, our 
network resilience held up well. We have invested 
millions of dollars in both our electricity and gas 
infrastructure to improve resilience and help reduce 
the impact of service interruptions. 

In December 2014 we received an award for 
excellence in energy efficiency from Platts Global 
Energy. Platts commended us for ongoing initiatives 
to upgrade equipment, reduce emissions, and 
improve safety and network efficiency. And in 
March 2015, the Edison Electric Institute presented 
us with its Emergency Recovery Award for our power 
restoration efforts following the severe ice storm 
in northern New York in December 2013. 

Safety 
Safety remains a hugely important priority for us. 
Regrettably, there were two fatalities during the year 
– a member of the public in the UK who fell when 
climbing on one of our pipelines, and a contractor 
at our Rhode Island gas distribution business. 
Despite these incidents, we achieved our best-ever 
Group safety performance during 2014/15. We can 
never be complacent about our performance and 
must continually strive to improve.

Our operations
We have continued to provide good value and 
reliability for customers while keeping our element 
of bills as low as possible. 

We are totally committed to providing the best 
value we can for our customers, investors and other 
stakeholders, so we’re working hard to make sure we 
are being as efficient as possible in everything we do. 
To help achieve this, we have continued to develop 
a way of working we call ‘Performance Excellence’, 
which you can read about on page 27. We also 
reorganised our UK business to increase clarity 
around what we do and who is accountable. 

In the US, we finally completed the stabilisation work 
on our new financial systems (see page 34). This 
fixed a number of long-standing problems, such as 
inefficient payroll processing, which had previously 
required expensive manual interventions. Long term, 

04

Strategic Reportthe robust data we can produce with the new 
systems is an essential foundation to the future 
performance improvements and regulatory filings 
that we need for profitable growth in the US.

It is increasingly recognised in the US that investment 
levels in some areas will need to rise compared with 
the earlier part of this decade, and we have seen 
increased activity this year, making it our highest 
ever year of US investment. 

In December 2014 the NYPSC approved $200 million 
gas infrastructure investment in Long Island to speed 
up the replacement of ageing pipe and extend the 
use of natural gas to more customers. 

The NYPSC also published the results of the 
regulatory audit of our New York gas companies. 
These audits are a regular feature of the New York 
regulatory process. The audit was broadly 
supportive of our performance and structure and, 
as is usual, made some helpful recommendations 
for further improvement. We have responded with 
an implementation plan to provide these benefits 
on behalf of New York customers.

As you can read on pages 18 and 19, our customer 
satisfaction scores were mixed. We exceeded our 
UK electricity and gas transmission targets. However, 
we did not meet our US targets and I recognise this 
is an area in which we must improve.

Responsible Business of the Year
As Sir Peter has described in his statement, 
National Grid was named Responsible Business 
of the Year 2014, which is BITC’s top award. I am 
extremely proud of this achievement, which is terrific 
recognition of how we are running a responsible 
and sustainable business, bringing long-term 
benefits to society. Although BITC is a UK body, 
the award was given to the entire Company and 
recognises the excellent work we’re doing across 
our entire service area in the UK and US.

For example, in the UK we are completing a test line 
for the T-pylon at our training academy. It is smaller 
than the existing lattice towers and provides 
communities with added choice. Our property 
business entered into a new arrangement with the 
Berkeley Group to develop a number of our sites in 
London and the surrounding area. The first phase of 
investments could lead to the development of over 
7,000 new homes, including affordable housing, 
alongside schools and public spaces.

Our EmployAbility programme provides supported 
internship opportunities for students with additional 
learning needs. Now into its second year, we have 
extended the programme and will continue to do this 
across more of our UK sites.

We are helping schools, parents and children 
see engineering as a modern, dynamic, desirable 
sector with a great future. Our careers education 
programmes in the UK include Careers Lab, an 
initiative we developed that has now been taken up 
by BITC. It links working professionals with schools 

to bring the world of work to life for secondary school 
children. Our US initiatives include partnering with 
seven local community colleges to deliver energy 
utility technology training programmes that are 
designed to equip people for jobs in the energy 
industry. We are doing a great deal of work in this 
area, as you can read on page 24.

operations

Our people 
pages 24–25

All this is business as usual for us – the BITC 
recognition is not the result of any special new 
initiative we have done to win the award. But it would 
not have been possible without the efforts of our 
employees. I was delighted to see that the results 
of our 2015 employee opinion survey – a good 
measure of how satisfied employees are with their 
employer – included an engagement score of 75% 
– our highest since we started conducting Group-
wide employee opinion surveys.

I would like to thank all our people for making a 
positive impact, through their work for National Grid, 
their volunteering and fundraising achievements, 
and by getting involved in activities that really matter 
to us and to society.

Priorities for 2015/16 
Safety: continue to build on our strong performance 
so we can achieve a consistent world-class 
safety performance;

Customers and stakeholders: improve the service 
we provide for our customers and continue to build 
trust among our stakeholders;

Performance Excellence: focus on being efficient 
in our end-to-end processes so we can continue to 
improve our overall performance and efficiency; and

Regulatory filings: prepare and file applications 
for new rate plans in New York, Long Island and 
Massachusetts.

Strategic ReportNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Operating environment
The UK economy has been recovering steadily in the past year, with 2.6% 
economic growth, falling unemployment and falling inflation.

Growth in the fourth quarter of 2014, however, dropped to 0.5% 
as sluggish eurozone growth depressed exports and wider 
geopolitical events increased the perceived risk of investment. 
In the US, employment levels have continued to rise. The Federal 
Reserve ended its quantitative easing programme of bond 
purchases, though treasury yields continue to be at or near 

historical lows. GDP increased 2.4% in 2014, although growth 
in the first quarter of 2015 was only 0.2%.

Below, we highlight our main market drivers and the impact 
they have on our business.

Market driver

Impact

Changing energy mix
Changing fuel costs and environmental programmes 
are affecting traditional electricity generation
UK
In February 2015 DECC announced the results of the first 
Contracts for Difference (CfD) auction allocation rounds, with 
wind technology making up the bulk of contracted generation. 
Continued support for solar PV through Feed in Tariffs (FiTs) and 
the Renewables Obligation contributed to growth in installed 
solar PV.

Older fossil fuel plants continue to face the challenge of 
environmental regulations while the new nuclear plant at Hinkley 
received State Aid approval from the European Commission in 
October 2014. 

US
In the US, shale gas development has continued to keep national 
wholesale prices low. 

Environmental Protection Agency regulations have led to generator 
retirements or increased costs for compliance. 

Renewables are growing their share of electricity generation 
and account for a significant amount of newly installed capacity. 
Distributed generation, such as rooftop solar, has grown 
substantially in our service territory.

Energy policy
Sustainability, security of supply and affordability 
underpin EU policy
Against a difficult economic and financial background, the EU’s 
energy policy is underpinned by sustainability, security of supply 
and affordability. In October 2014 the EU heads of state agreed the 
EU’s 2030 Climate Change and Energy Framework. This includes 
a 40% reduction target for carbon emissions, alongside other 
objectives for renewables, energy efficiency and interconnections. 

Negotiations for a new international agreement on climate change 
continued at the twentieth session of the Conference of Parties 
(COP20) in Lima in December 2014. Nations are looking to the 
Paris worldwide conference in 2015 as the next opportunity to 
work out a new climate change deal. 

Finally, the creation of a ‘genuine energy union’ was highlighted 
as one of the main priorities of the new European Commission, 
which took office in November 2014.

UK energy policies are attracting investment and there is 
significant political focus on reducing costs for consumers
Energy policy continues to evolve from the Climate Change Act 
2008, which commits the UK Government to reducing UK 
greenhouse gas emissions to at least 80% lower than a 1990 
baseline by 2050. The Energy Act 2013 implements the main 
aspects of EMR, and puts in place measures to attract the 
investment needed. The run-up to the General Election in 
May 2015, saw a sharp focus on the costs of energy and the 
competitiveness of energy markets.

This could lead to significant network investment 
opportunities
UK
Increasing deployment of large-scale wind, large-scale solar 
PV and nuclear will require more investment in transmission 
networks to connect new plant and reinforce the network. 
Variable output from solar PV and wind makes balancing 
demand and supply more challenging.

More interconnection between the UK and adjacent European 
markets will deliver net benefits to the UK.

US
Lower national wholesale gas prices have increased the amount 
of gas used for electric generation, causing constraints into the 
northeast US.

Oil to gas conversions will continue as gas maintains its price 
advantage. New interstate gas pipeline capacity is needed to 
overcome growing gas demand.

The electric transmission system will need upgrades and 
rebalancing due to generation retirements and to connect new 
renewable sources. Increasing amounts of distributed generation, 
particularly solar, will require investment in the electric 
distribution network.

Policy decisions can affect our investment needs and 
compliance obligations
Greater levels of market integration, interconnection and 
renewable generation are fundamental to achieving the EU’s 
policy objectives. 

While European developments present challenges, the 
significant level of investment required will create opportunities 
for growth. For example, potential future interconnector 
opportunities include connections between the UK and France, 
Ireland, Denmark and Iceland. Such opportunities would help 
the EU achieve its interconnection targets. See page 27 for more 
information about our interconnector projects.

National Grid is central to the delivery of EMR and active 
on driving down costs 
National Grid has been performing its role as delivery body 
for the Government on EMR, as described on page 39.

The focus on the cost of energy is important to National Grid. 
We are working hard to highlight to our stakeholders how the 
RIIO regulatory framework is helping us to reduce costs for 
consumers while creating incentives for vital investment.

Strategic ReportMarket driver

Impact

US policy is evolving to meet environmental and energy 
diversity goals
In the US, many federal level developments have been through 
federal agency regulations and Presidential executive orders. At 
a state level, energy policy continues to evolve in the northeastern 
US, driven by interest in promoting energy efficiency, maintaining 
reliability and deploying renewable technologies that help meet 
environmental and energy diversity goals.

Options for increased renewable and distributed 
generation are being explored
In the US, the impact on natural gas dependency has resulted 
in an evaluation of the best way of increasing fuel diversity 
through renewable and distributed generation resources. 
We continue to support movement towards a clean energy 
economy; and support additional measures to increase 
America’s energy productivity.

Regulation
Infrastructure investment needs must be balanced 
with affordability
Regulators acknowledge that there is a significant need for 
infrastructure investment. However, affordability continues to 
be a primary concern. 

Ageing gas mains can be riskier to use and can contribute 
to greenhouse gas emissions through leaks. Regulators and 
policymakers are asking utilities to put plans in place to strengthen 
their networks’ ability to withstand the effects of severe weather.

We must accommodate customers’ cost concerns and 
also provide safe, up-to-date systems
We must accommodate our customers’ affordability concerns 
while fulfilling our obligations to provide safe and reliable services 
and upgrading our systems. Investment is required for new 
connections, to meet the challenges of changing supply and 
demand patterns, and to replace ageing infrastructure in the 
UK and US.

UK regulators want greater efficiency and innovation
In the UK, the regulatory focus during the year has been on the RIIO 
price controls which give greater focus to incentives and innovation 
than the previous regulatory regime.

This is driving them to favour more market competition
In the UK, competition is already in place for offshore 
development and Ofgem has stated its intent to retain the option 
of using greater competition for certain large onshore projects.

We continue to be engaged in the debate on the regulatory approach 
to electricity transmission investment, stemming from the projected 
increase in offshore wind generation and interconnection.

In the UK, Ofgem is reviewing the arrangements for planning 
and delivering Britain’s transmission networks
We are facing new challenges from an ageing infrastructure and a 
changing energy mix. Technical developments and innovation also 
mean that there could be opportunities to coordinate and integrate 
those investments.

The Integrated Transmission Planning and Regulation (ITPR) 
project is looking at long-term challenges such as ageing 
infrastructure, the changing energy mix, technical developments 
and innovation, to assess whether the regulatory arrangements 
currently in place are sufficient to ensure coordination and 
efficiency in the future planning of electricity transmission.

US regulators are focused on system modernisation 
and integration of new distributed energy resources
State officials in Massachusetts and New York have approved 
gas system investment programmes to accelerate replacement 
of ageing infrastructure. The Massachusetts Grid Modernization 
proceeding and New York’s Reforming the Energy Vision effort 
both focus on deploying advanced electric grid capabilities to 
improve reliability, more fully exploit distributed energy resources, 
and provide new opportunities for customers to control their 
energy use.

For more information about network efficiency and innovation, 
see pages 27 to 31.

We need to make sure the network is planned in an 
economic, efficient and coordinated way
Ofgem has proposed enhancing our role as System Operator 
(SO) so that the SO has a greater role in system planning. No 
organisation is currently responsible for taking an overarching 
view of system development, so opportunities for coordination 
can potentially be missed. We are working with Ofgem to 
develop the framework for how the system will be planned 
and how assets will be managed.

Investments to modernise networks and integrate 
distributed resources will offer new options and value 
to customers
We are expanding gas system enhancement investment 
programmes and are developing electric grid modernisation 
plans. Through our regulatory efforts and stakeholder 
engagement we are seeking to create a regulatory framework 
that integrates distributed energy resources into the electric grid 
in a way that is cost effective and delivers benefits to customers.

In the US, FERC is reforming transmission planning and 
promoting competition in the transmission industry
FERC issued Order 1000 in 2011 to improve transmission planning 
and increase competition in the transmission industry. Policies to 
comply with the Order took effect in New York and New England 
in 2014 and 2015, respectively.

Competitive transmission planning provides opportunities 
for us 
Order 1000 has opened our service territory to competition from 
non-incumbent transmission developers and also created 
opportunities for us to compete for transmission projects 
outside of our current geographic footprint.

Innovation and technology
Performance improvements and cost declines have led 
to continued growth in new technologies
Distributed generation of solar power has grown significantly due 
to price declines and tax incentives. Energy storage is growing 
in the US as certain states set goals and other utilities announce 
investment plans for storage capacity.

The UK hit a record high for wind generation in 2014 of 28 terawatt 
hours (TWh), 15% greater than the previous year. 

Plug-in electric vehicle sales in the US and worldwide grew, 
even as gasoline prices dropped throughout the past year.

Further investment in electricity distribution networks may 
be necessary to integrate these new technologies
Investment in renewable energy continues to grow. Regulatory 
proceedings are underway to enhance the value of distributed 
resources to the grid and give customers more control over their 
energy use. 

These could require significant network investment in order to 
integrate new and variable resources and provide customers 
with more information on their usage.

Strategic ReportNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15What we do – Electricity
The electricity industry connects generation sources to homes and businesses 
through transmission and distribution networks. Companies that pay to use 
transmission networks buy electricity from generators and sell it to consumers.

System operator
As system operator (SO) for England and Wales, 
we coordinate and direct electricity flows onto 
and over the transmission system, balancing 
generation supply and user demand. Where 
necessary, we pay sources of supply and demand 
to increase or decrease their generation or usage.

We have the same role for the two high voltage 
electricity transmission networks in Scotland 
and we are SO for the offshore electricity 
transmission regime.

will deliver significant benefits to consumers. 
These include opportunities for interconnection with 
Iceland, Denmark and a further link with France.

Our business 
model 
pages 12–13

We also jointly own and operate a 224 kilometre 
interconnector between New England in the US 
and Canada.

We sell capacity on our UK interconnectors through 
auctions and on our US interconnector through 
wholesale markets and bilateral contracts.

3   Transmission

Our charges for SO services in the UK are subject 
to a price control approved by Ofgem. System 
users pay us for connection, for using the system 
and balancing services.

Transmission systems generally include overhead 
lines, underground cables and substations. They 
connect generation and interconnectors to the 
distribution system.

As electricity transmission SO, our price control 
includes incentives to minimise the costs and 
associated risks of balancing the system through 
buying and selling energy, as well as procuring 
balancing services from industry participants.

In the US, similar services are provided by 
independent system operators.

1   Generation

We own and operate the transmission network in 
England and Wales. We operate but do not own the 
Scottish networks. We are also working in a joint 
venture with Scottish Power Transmission to construct 
an interconnector to reinforce the GB transmission 
system between Scotland and England and Wales.

In the US, we jointly own and operate transmission 
facilities spanning upstate New York, Massachusetts, 
New Hampshire, Rhode Island and Vermont.

Generation is the production of electricity from fossil 
fuel and nuclear power stations, as well as renewable 
sources such as wind and solar. In the US, we own 
and operate 50 fossil fuel-powered stations on 
Long Island and 4.6 MW of solar generation in 
Massachusetts. We do not own or operate any 
electricity generation in the UK.

4   Distribution

Distribution systems carry lower voltages than 
transmission systems over networks of overhead 
lines, underground cables and substations. They 
take over the role of transporting electricity from the 
transmission network, and deliver it to consumers 
at a voltage they can use.

We sell the electricity generated by our plants on 
Long Island to LIPA under a long-term power supply 
agreement. The contract allows us to recover our 
efficient operating costs and provides a return on 
equity on our investment in the generation assets.

For solar generation, we recover our costs and a 
reasonable return from customers in Massachusetts 
through a solar cost adjustment factor. This is added 
to the electricity rate, net of revenues earned from the 
solar assets.

2   Interconnectors

Transmission grids are often interconnected so 
that energy can flow from one country or region to 
another. This helps provide a safe, secure, reliable 
and affordable energy supply for citizens and society 
across the region. Interconnectors also allow 
power suppliers to sell their energy to customers 
in other countries.

Great Britain is linked via interconnectors with France, 
Ireland, Northern Ireland and The Netherlands. 
National Grid owns part of the interconnectors with 
France and The Netherlands. We are also now 
entering the construction phase for two new 
interconnectors, between the UK and Belgium and 
Norway. We are continuing to work on developing 
additional interconnector projects, which we believe 

08

We do not own or operate electricity distribution 
networks in the UK.

In the US, our distribution networks serve around 
3.5 million customers in upstate New York, 
Massachusetts and Rhode Island.

5   Supply

The supply of electricity involves buying electricity 
and selling it on to customers. It also involves 
customer services, billing and the collection of 
customer accounts.

We do not sell electricity to consumers in the UK.

All our customers in the US can select a competitive 
supplier for the supply component of electricity utility 
services. Where customers choose National Grid, 
they pay us for distribution and electricity costs. 
Where they choose to buy electricity from third 
parties, they pay us for distribution only and pay 
the third-party supplier for the electricity. Our base 
charges for electricity supply are calculated to 
recover the purchased power costs.

Strategic ReportWhat we do – Gas
The gas industry connects producers, processors, storage, transmission 
and distribution network operators, as well as suppliers to industrial, 
commercial and domestic users.

System operator
As system operator we are responsible for the 
high pressure gas National Transmission System 
(NTS) in Great Britain. We have responsibility for 
the residual balancing activities on the NTS and 
for keeping the physical system within safe 
operating limits. 

Our price control, set by Ofgem, includes 
incentives that aim to maintain and improve 
our daily operational efficiency and are subject 
to renegotiation at set intervals.

1   Production and importation

Gas used in the UK is mainly sourced from gas fields 
in the North and Irish seas, piped from Europe and 
imported as LNG. 

There are seven gas reception terminals, three LNG 
importation terminals and three interconnectors 
connecting Great Britain via undersea pipes with 
Ireland, Belgium and the Netherlands. Importers 
bring LNG from the Middle East, the Americas and 
other places.

We are the sole owner and operator of gas 
transmission infrastructure in Great Britain.

In the US, we hold a minority interest in two interstate 
pipelines: Millennium Pipeline Company and Iroquois 
Gas Transmission System. Interstate pipelines are 
regulated by the Federal Energy Regulatory 
Commission (FERC).

3   Distribution

In the UK, gas leaves the transmission system and 
enters the distribution networks at high pressure. 
It is then transported through a number of 
reducing pressure tiers until it is finally delivered 
to consumers.

There are eight regional gas distribution networks 
in the UK, four of which are owned by National Grid. 
In the US, gas is delivered by the interstate pipeline 
companies to local distribution networks. Each local 
distribution company has a geographically defined 
service territory and is the only local distribution 
company within that territory. Local distribution 
companies are regulated by the relevant local state’s 
utility commission.

Gas used in the US is produced mainly in North 
America. We import LNG from a number of countries. 

Our networks deliver gas to 10.9 million consumers 
in the UK and 3.6 million customers in the US.

We do not produce gas in either the UK or US.

4   Supply

Pipeline shippers bring gas from producers 
to suppliers, who in turn sell it to customers.

We do not supply gas in the UK. However, we own 
National Grid Metering, which provides meters 
and metering services to supply companies, 
under contract.

In the UK, customers pay the supplier for the cost of 
gas and for its transportation. We transport the gas 
through our network on behalf of shippers, who pay 
us transportation charges.

In the US, gas distribution companies, including 
National Grid, sell gas to consumers connected 
to their distribution systems.

In most cases in the US, where customers choose 
National Grid, they pay us for distribution and gas 
costs. Where they choose to buy gas from third 
parties, they pay us for distribution only and pay 
the third-party supplier for the gas and upstream 
transportation capacity.

Also in the US, except for residential consumers in 
Rhode Island, customers may purchase their supply 
from independent providers with the option of billing 
for those purchases to be provided by us.

In the UK, we own and operate Grain LNG, an 
importation terminal and storage facility at the 
Isle of Grain in Kent, which charges customers 
under long-term contracts for various services. 
These include access to our importation terminal, 
storage facilities and capacity rights.

In the US, we own and operate LNG storage and 
vaporisation facilities, as well as an LNG storage 
facility in Providence, Rhode Island, where we store 
gas for third parties for a fee. We also buy gas 
directly from producers and LNG importers for 
resale to our customers.

2   Transmission

The transmission systems generally include pipes, 
compressor stations and storage facilities, including 
LNG storage. They connect production through 
terminals to the distribution systems.

In the UK, gas enters the transmission system 
through importation and reception terminals and 
interconnectors and may include gas previously 
held in storage. 

Compressor stations located along the network 
play a vital role in keeping large quantities of gas 
flowing through the system, particularly at times 
of high demand. 

The gas transmission system has to be kept 
constantly in balance, which is achieved by buying, 
selling and using stored gas. This means that, 
under normal circumstances, demand can be met.

How we generate long-term value.

Our business

Our value proposition

We are a long-term, asset-based business. Our operations 
are regulated, which means we create value for our 
stakeholders through predictable revenue streams 
and cash flows. 

Our strategy is to be a recognised leader in the 
development and operation of safe, reliable and 
sustainable energy infrastructure, to meet the needs 
of our customers and communities and to generate 
value for our investors. 

We own and operate gas and electricity transmission 
and distribution infrastructure in the UK and 
northeastern US. Our principal operations are:

•  UK Electricity Transmission
•  UK Gas Transmission
•  UK Gas Distribution
•  US Regulated
•  Other activities (such as Grain LNG, 

Interconnectors and Metering)

We aim to maintain a clear and consistent strategy 
over the long term to provide stable returns to our 
investors and consistent levels of service to our 
customers and communities.

  Our vision and strategy: pages 14–15 
  Principal operations: pages 27–36

Our transmission and distribution businesses operate 
as regulated monopolies. Regulators safeguard 
customers’ interests by setting the level of charges 
we are allowed to pass on. 

In the UK, we have one regulator for our businesses: 
Ofgem. In the US, for the areas in which we operate, 
we are regulated by the relevant state regulators 
and FERC. 

The foundations of our business model
Our people, being a responsible business, and 
encouraging innovation are at the heart of our business 
model and are reflected in our strategy. 

12

Revenue

Most of our revenue is set in accordance with 
our regulatory agreements. This is referred to as 
our ‘allowed revenue’ and is calculated based on 
a number of factors. These include: 

•  investment in network assets; 
•  performance against incentives;
•  return on equity and cost of debt; and 
•  customer satisfaction scores. 

You can find more information about calculating 
our allowed revenue under our UK and US 
regulatory agreements on pages 20 to 23.

Our allowed revenue gives us a level of certainty 
over future revenues if we continue to meet 
safety and reliability targets, as well as the 
efficiency and innovation targets included 
in the RIIO licence agreements in our UK 
regulated businesses.

Investment

We invest efficiently in our networks to deliver strong 
regulated asset growth over the long term. This 
allows us to continue generating revenue growth and 
growth in our regulated asset base. This in turn 
generates additional cash flows and allows us to 
continue reinvesting in our networks and providing 
sustainable dividends to our shareholders. 

Our people
Our business is built on our people. 
We work hard to make sure that we keep 
them as safe as possible as well as 
providing an inclusive culture and 
encouraging development. 

 Our people: pages 24–25

Strategic ReportInvestment

These cash flows are then reinvested to provide future 
growth, or returned to shareholders. 

Our stakeholders
Our stakeholders include customers, the 
communities in which we operate, shareholders, 
governments and regulators. 

Cash flow

Our ability to convert revenue to cash is an 
important factor in the ongoing reinvestment in 
our business. Securing low-cost funding, 
carefully managing our cash flows and efficient 
development of our networks are essential to 
maintaining strong sustainable returns for our 
shareholders. Cash generation is underpinned by 
agreeing appropriate regulatory arrangements.

This approach is critical to the sustainability of our 
business. By challenging our investment decisions, 
we continue to deliver reliable, cost-effective 
networks that benefit our customers. The way in 
which our investment is funded is also an important 
part of our business. The long-term, sustainable 
nature of our assets and our credit ratings help us 
secure efficient funding from a variety of sources.

We create value for our customers 
and communities by:
•  operating safely, reliably and sustainably;
•  focusing on affordability to reduce the impact 

on customer bills;

•  delivering essential services that meet the 

needs of our customers;

•  providing emergency services; and
•  engaging with the communities in which 

we operate. 

We create value for our shareholders by: 
•  making sure our regulatory frameworks maintain 
an acceptable balance between risk and return;

•  operating within our regulatory frameworks as 

efficiently as possible;

•  maximising incentives to make the most of our 

allowed returns;

•  careful cash flow management and securing 

low-cost funding;

•  disciplined investment in our networks and 

non-regulated assets; and
•  protecting our reputation.

Using our knowledge and expertise, we engage 
widely in the energy policy debate to help guide future 
policy direction. We also work with our regulators to 
help them develop the frameworks within which we 
can meet the changing energy needs of the 
communities we serve. 

 How our strategy creates value: pages 14–15 

Being a responsible business

How our strategy creates value
Our vision and strategic objectives explain what is important to us, so we can meet our 
commitments and deliver value.

Customer and community value
Safety and reliability – we strive to provide 
reliable networks safely, which is essential to 
safeguard our customers, employees and the 
communities in which we operate.

Affordability – we strive to provide services 
efficiently, which helps to reduce the 
amount of money consumers have to pay 
for their energy.

Customer service – providing essential 
services that meet the needs of our 
customers and communities is a crucial 
part of the value they expect from us.

Sustainability – we strive to protect the 
environment and preserve resources for 
current and future generations. 

Emergency services – we provide telephone 
call centres, coordinate the response to 
gas emergencies, and respond to severe 
weather events.

Community engagement – we listen to 
the communities we serve and work hard to 
address concerns about the development of 
our networks. Our employees volunteer for 
community-based projects and we support 
educational initiatives in schools.

Shareholder value
Regulatory frameworks – operating within 
sound regulatory frameworks provides 
stability. Making sure these frameworks 
maintain a balance between risk and return 
underpins our investment proposition.

Reputation – our approach to safety and 
our reliability record underpin our reputation. 
These are crucial factors that contribute 
towards positive regulatory discussions and 
help us pursue new business opportunities. 

Efficient operations – efficient capital and 
operational expenditure allows us to deliver 
network services at a lower cost and reduces 
working capital requirements.

Maximising incentives – if we perform well 
against our incentives, and deliver the outputs 
our customers and regulatory stakeholders 
require, we can make the most of our allowed 
returns.

Funding and cash flow management 
– securing low-cost funding and carefully 
managing our cash flows help us maintain 
strong returns for our investors. 

Disciplined investment – we can increase 
our revenue and earnings by investing in 
both regulated and non-regulated assets. 
This helps us deliver attractive returns for 
our shareholders.

KPI and definition

Adjusted EPS

Adjusted earnings represent profit for the 

year attributable to equity shareholders. This 

excludes exceptional items, remeasurements 

and stranded cost recoveries (see pages 

103 and 104).

Adjusted earnings per share provides a 

measure of shareholder return that is 

comparable over time.

We measure our performance in generating 

value for our shareholders by dividing our 

annual return by our equity base.

This calculation provides a measure of the 

performance of the whole Group compared 

with the amounts invested by the Group in 

assets attributable to equity shareholders.

We are adding new KPIs to better reflect the issues that matter most to our Company and our stakeholders. For this 2014/15 Report, 
we have included information about workforce diversity, as set out on pages 18 and 19. We aim to include two further new KPIs 
in our 2015/16 Report. These relate to community engagement and investment in education, skills and capabilities. Executive 
remuneration is linked to some of our KPIs.

Commentary

For the year ended 31 March 2015, adjusted earnings 
attributable to equity shareholders increased 
by £174 million to £2,189 million. This increase in 
earnings resulted in an adjusted earnings per share 
of 58.1 pence, an increase of 9% on 2013/14.

Overall adjusted net finance costs reduced by 
£75 million across the Group which was broadly 
offset by a higher adjusted tax charge of £114 million 
reflecting the increase in profits across the Group.

 See page 20

The earnings increase was driven by a £199 million 
increase in adjusted operating profit. With the 
exception of our UK Gas Distribution business, 
we saw increases in adjusted operating profit 
across all of our business segments.

Group RoE has increased during the year to 11.8%, 
from 11.4% in 2013/14.

The UK regulated businesses delivered good returns 
of 13.7% in aggregate in the second year of their new 
price controls, including the assumed 3% long run 
average RPI inflation. 

US returns of 8.4% were slightly down on last year, 
reflecting the additional costs incurred on gas leak 
repair and compliance and the increased level of rate 
base growth since 2013.

Our regulated assets have increased by 7% (£2.3 billion) 
to £37.0 billion. This reflects the continued high levels 
of investment in our networks in both the UK and US, 
together with the impact of the stronger US dollar.

The rate of growth at constant currency was 3%.

The UK regulatory asset value (RAV) increased by 
£0.5 billion, reflecting significant capital expenditure, 
together with inflation, although at 0.9% RPI, this has 
had a smaller impact than in recent years. US rate 
base has increased by £1.8 billion this year. Of this, 
£1.2 billion was due to foreign exchange movements 
increasing the rate base reported in sterling. Excluding 
foreign exchange, rate base increased by £0.6 billion, 
reflecting a record year of US investment.

No specific target. 
Our overall aim 
is to increase 
regulated asset 
growth above the 
underlying rate 
of inflation.

 See page 21

Value added in the year was lower than 2013/14, 
primarily due to the impact of lower RPI on UK regulated 
asset growth. RPI inflation for March 2015 was 0.9% 
compared with 2.5% in March 2014 and National Grid’s 
long run assumption of 3%. 

Of the £1.7 billion value added in 2014/15, £1,271 million 
was paid to shareholders as cash dividends and 
£335 million as share repurchases (offsetting the scrip 
issuance during the year), with £79 million retained in 
the business.

In the UK we maintained a world-class employee safety 
performance during 2014/15, with an employee injury 
frequency rate of 0.09. Our US business improved its 
safety performance, with an employee injury frequency 
rate of 0.15. 

Overall, our Company-wide injury frequency rate of 0.13 
is better than last year and means that we bettered our 
target of 0.15. However, we did not meet our ambition to 
reach a world-class level by 2015. 

We achieved our 
Company-wide

For the year ended 31 March 2015, adjusted 
operating profit in the UK Electricity Transmission 
segment increased by £150 million. Net regulated 
income after pass-through costs was £230 million 
higher, principally reflecting increases in allowed 
transmission owner revenues this year and a 
£43 million benefit relating to legal settlements. 
This was partially offset by under-recoveries of 
allowed revenue in the year of £89 million compared 
with under-recoveries of £60 million in the prior year. 
Regulated controllable costs were £14 million higher 
due to inflation, organisational change costs and 
additional tower maintenance costs. Depreciation 
and amortisation was £33 million higher reflecting 
the continued capital investment programme, and 
other costs were £4 million higher than prior year.

UK Gas Transmission adjusted operating profit 
increased by £20 million to £437 million. Net 
regulated income after pass-through costs was 
£42 million higher due to earned gas permit and 
constraint management incentives. In addition, 
under-recoveries of allowed revenue in the year of 
£18 million were £3 million favourable to last year’s 
under-recoveries of £21 million. Partially offsetting 
the revenue gains, regulated controllable costs 
were £8 million higher, including additional system 
operator costs relating to EU work. Other operating 
costs were also £17 million higher, including 
decommissioning costs of the Avonmouth LNG plant. 

UK Gas Distribution adjusted operating profit 
decreased to £826 million from £904 million in 
2013/14. Net regulated income after pass-through 
costs was £11 million lower, reflecting changes in 
allowed revenues for repex expenditure. Timing 
differences reduced net revenues by a further 
£16 million, with £13 million over-recoveries in 
2014/15 compared with a £29 million over-recovery 
in the prior year. Regulated controllable costs were 
£22 million higher primarily due to inflation and 
organisational change costs. Depreciation and 
amortisation was £15 million higher reflecting the 
continued capital investment programme, and other 
costs were £14 million higher than prior year, including 
provision for additional asset protection costs.

Within our US Regulated businesses, adjusted 
operating profit increased by £39 million to 
£1,164 million. The stronger dollar increased operating 
profit in the year by £30 million. Excluding the impact of 
foreign exchange, net regulated income increased by 
£81 million, reflecting increased revenue allowances 
under the Niagara Mohawk three year rate plan and 
other regulated revenue increases, partially offset by 
the impact of the end of LIPA management services 
agreement (MSA) in December 2013. In addition, 
over-recoveries of allowed revenues in the year of 
£30 million were £20 million favourable to last year’s 
over-recoveries of £10 million. Regulated controllable 
costs increased by £17 million excluding the impact 
of foreign exchange, as a result of increased gas leak 
and compliance work and additional costs incurred 
to improve data quality to bring regulatory filings up 
to date. This was partly offset by the removal of costs 
associated with the LIPA MSA activities. Following last 
year’s exceptionally cold winter, bad debt costs were 
£62 million higher excluding the impact of foreign 
exchange. There were no major storms affecting our 
operations in the years ended 31 March 2014 and 2015.

Adjusted operating profit in Other activities was 
£68 million higher at £199 million. Operating profit in 
the French interconnector was £18 million higher as a 
result of strong auction revenues this year. In the US, 
corporate and other activities losses were £63 million 
lower, mainly as a result of the completion of the 
enterprise resource planning system stabilisation 
in the first half of the year.

Adjusted earnings
For the year ended 31 March 2015, adjusted net 
finance costs were £75 million lower than 2013/14 
at £1,033 million, mainly as a result of lower average 
gross debt through the year, lower RPI rates in the 
UK and refinancing debt at lower rates.

The adjusted tax charge was £114 million higher 
than 2013/14. This was mainly due to higher profits 
before tax and the non-recurrence of one-off items 
that benefited the prior year. As a result of this, 
the effective tax rate for 2014/15 was 24.2% 
(2013/14: 22.5%).

The earnings performance described above has 
translated into adjusted earnings of £2,189 million, 
up £174 million on last year. This equates to adjusted 
earnings per share (EPS) of 58.1 pence, up 4.6 pence 
(9%) on 2013/14.

Scrip restatement
In accordance with IAS 33, all EPS and adjusted EPS 
amounts for comparative periods have been restated 
as a result of shares issued via scrip dividends.

Measurement of financial performance
We describe and explain our results principally on 
an adjusted basis and explain the rationale for this 
on page 186. We present results on an adjusted 
basis before exceptional items, remeasurements 
and stranded cost recoveries. See page 186 for 
further details and reconciliations from the adjusted 
profit measures to IFRS, under which we report 
our financial results and position.

Strategic ReportThis section provides additional commentary on our KPIs and other performance metrics we use to monitor our business 
performance. Analysis of our financial performance and position as at 31 March 2015, including detailed commentary on the 
performance of our operating segments, is located in the financial statements. However, this analysis still forms part of our 
Strategic Report financial review. See page 77 for further information. See pages 187 to 189 for commentary on our financial

Group return on equity (RoE)
We measure our performance in generating value for 
our shareholders by dividing our annual return by our 
equity base.

Group RoE has increased during the year to 11.8%, 
from 11.4% in 2013/14. During the year, the UK 
regulated businesses delivered good returns of 
13.7% in aggregate in the second year of their new 
price controls (2013/14: 12.7%), including the assumed 
3% long-run average RPI inflation. US returns (on a 
higher average equity ratio than the UK) of 8.4% 
were down on last year, reflecting the additional 
costs incurred on gas mains repair and emergency 
leak response and the increased level of rate base 
growth since 2013. Overall, other activities in the 
Group delivered a good performance, including an 
improved result from the French interconnector and 
lower US corporate costs following the completion of 
the enterprise resource planning system stabilisation 
during the year. Treasury performance also helped 
the result, partly assisted by lower RPI accretions 
on the Group’s index-linked debt. Together, these 
helped to offset the headwind from lower cost of 
debt allowances under the tracker within the new 
UK price controls. 

Regulated asset growth
In total our UK regulated asset value (RAV) and 
US rate base increased by £2.3 billion (7%) to 
£37.0 billion. This reflects the continued high levels 
of investment in our networks in both the UK and US, 
together with the impact of the stronger US dollar. 
The rate of growth at constant currency was 3%.

The UK RAV increased by £0.5 billion, reflecting 
significant capital expenditure, together with inflation, 
although at 0.9% RPI, this has had a smaller impact 
than in recent years. UK RAV growth also included 
capitalised efficiencies or ‘performance RAV’ of 
£111 million this year.

US rate base has increased by £1.8 billion this year. 
Of this, £1.2 billion was due to foreign exchange 
movements increasing the rate base reported in 
sterling. Excluding foreign exchange, rate base 
increased by £0.6 billion, reflecting a record year 
of US investment.

Value added
Our dividend is an important part of returns to 
shareholders along with growth in the value of the 
asset base attributable to equity investors. These are 
reflected in the value added metric that underpins 
our approach to sustainable decision-making and 
long-term incentive arrangements.

1.  Includes assets held outside RAV and rate base.

Value added in the year was lower than 2013/14 
(£2.1 billion or 57.2 pence per share), primarily led 
by the impact of lower RPI on UK regulated asset 
growth. RPI inflation for March 2015 was 0.9% 
compared with 2.5% in March 2014 and National 
Grid’s long-run assumption of 3.0%. Of the 
£1.7 billion value added in 2014/15, £1,271 million 
was paid to shareholders as cash dividends and 
£335 million (excluding £3 million of transaction costs) 
as share repurchases (offsetting the scrip issuance 
during the year), with £79 million retained in 
the business.

The Board is confident that growth in assets, 
earnings and cash flows, supported by improving 
cash efficiency and an exposure to attractive 
regulatory markets, should help the Group to 
maintain strong, stable credit ratings and a 
consistent prudent level of gearing, while delivering 
attractive returns for shareholders.

Other performance measures
UK regulated return on equity
The UK RoE has increased 100bps to 13.7%, 
reflecting particularly strong incentive performance 
in the Gas Transmission business and further 
outperformance against our totex targets in Electricity 
Transmission, achieved through efficiencies within 
the capital investment programme. This performance 
represents 360bps outperformance over allowed 
returns. Our UK RoE does not include the impact of 
legal settlement benefits of £56 million. If these were 
included UK RoE would increase by 60bps to 14.3%.

1.  Calculated on a calendar year basis.

Cash generated from operations
Cash generated from operations was £5,350 million 
(2013/14: £4,419 million). Changes in working capital 
improved by £360 million over the prior year, 
principally in the US (£441 million) due to the 
collection of high winter 2014 billings and other 
settlements including Superstorm Sandy reinsurance 
claims and LIPA receipts. Cash outflows relating to 
exceptional items were £133 million lower, as the 
prior year included reorganisation costs in the UK 
and LIPA MSA transition costs in the US.

Net debt and credit metrics
Our net debt levels will continue to grow for the 
next few years as we fund our capital investment 
programmes and enhance our networks. We continue 
to borrow at attractive rates when needed and the 
level of net debt remains appropriate for our business. 

During 2014/15, net debt has increased by £2.7 billion. 
This is predominantly due to movements in foreign 
exchange rates as the US dollar strengthened 
against sterling. Gross borrowings are relatively 
consistent year on year, reflecting the current year 
net refinancing of maturities and bond repurchases, 
while cash and investment levels have been actively 
managed down. 

With the commencement of the RIIO price controls 
in 2013 and the slow down in our planned near-term 
UK capital investment programme as the industry 
assesses the impact of Electricity Market Reform, 
we reviewed and restructured the Group debt 
portfolio. The review resulted in a £924 million bond 
repurchase programme, of which £295 million was 
achieved through a cash tender offer for five bonds. 
The net repurchase cost of £131 million has been 
presented as exceptional finance costs in the 
income statement, as noted on page 104.

22

A key measure we use to monitor financial discipline is 
retained cash flow divided by adjusted net debt (RCF/
net debt). This is a measure of the operating cash 
flows we generate, before capital investment but after 
dividends paid to shareholders, compared with the 
level of debt we hold. The principal adjustment made 
to net debt is to include pension deficits. RCF/net 
debt was 11.2% for the year (2013/14: 10.5%; 
2012/13: 11.4%). For the current year we have used 
this measure to actively manage scrip uptake through 
buying back shares when supported by sufficient 
headroom. Deducting the cost of buying back these 
shares reduces RCF/net debt to 9.9% for the year.

Our long-term target range for RCF/net debt is to 
exceed 9.0%, which is consistent with the A3 rating 
threshold used by Moody’s, the rating agency.

We additionally monitor interest cover, which is a 
measure of the cash flows we generate compared 
with the net interest cost of servicing our borrowings. 
Interest cover for the year was 5.1 times (2013/14: 
4.1 times; 2012/13: 3.9 times). Our target long-term 
rate for interest cover is in excess of 3 times.

Return on capital employed
RoCE provides a performance comparison between 
our regulated UK and US businesses and is one of 
the measures that we use to monitor our portfolio 
of businesses. The table below shows our RoCE 
for our businesses over the last five years:

The UK RoCE has increased from 8.0% to 8.6% 
in 2014/15. This reflects the strong incentive 
performance in Gas Transmission and further totex 
outperformance in Electricity Transmission, together 
with one-off benefits of legal settlements in the year.

US RoCE has decreased by 40bps in the year to 
6.0%, as a result of the additional maintenance to 
improve reliability and safety and bring regulatory 
filings up to date, together with rate base growth 
driven by capital expenditure spend.

Capital expenditure
For the year ended 31 March 2015, capital 
expenditure of £3,470 million was at a similar level to 
last year, with reductions in spend in UK Electricity 
Transmission being offset by increases in capital 
spend in our US Regulated businesses.

The reduction in spend in UK Electricity Transmission 
reflected delays in the manufacture of cable for 
the Western HVDC link and a reduced level of 
overhead line work, with a number of projects 
having completed over the last two years. In addition 

Strategic Reportwe continue to look for innovative ways to reduce 
total expenditure (totex) under our RIIO regulatory 
arrangements while still delivering agreed outputs.

The amounts calculated as timing differences are 
estimates and subject to change until the variables 
that determine allowed revenue are final. 

Within our US Regulated businesses, capital 
expenditure was higher year on year reflecting higher 
levels of mains replacement work, gas system 
reinforcement and growth spend, electricity capacity 
spend and progress on the New England East-West 
Solution (NEEWS) electricity transmission project.

Our operating profit for the year includes a total 
estimated in-year under-collection of £64 million 
(2013/14: £42 million under-collection). Our closing 
balance at 31 March 2015 was £27 million 
under-recovered.

Dividend growth
We remain committed to our dividend policy to grow 
the dividend at least in line with the rate of average 
RPI inflation each year for the foreseeable future. 

During the year we generated £2.1 billion of 
business net cash flow after our capital expenditure 
programmes. This has enabled the growth of the 
dividend in line with average RPI, being 2.0% 
(2013/14: 2.9%; 2012/13: 4.0%), taking into account 
the recommended final dividend of 28.16 pence.

During the year, the Company has repurchased 
shares in the market with the overall goal being 
to reduce the dilutive effect of the scrip as much 
as possible to the extent that is consistent with 
maintaining the Group’s strong financial position 
as reflected in its credit rating.

Regulatory financial performance
Timing and regulated revenue adjustments
As described on pages 166 to 172, our allowed 
revenues are set in accordance with our regulatory 
price controls or rate plans. We calculate the tariffs 
we charge our customers based on the estimated 
volume of energy we expect will be delivered during 
the coming period. The actual volumes delivered will 
differ from this estimate. Therefore, our total actual 
revenue will be different from our total allowed 
revenue. These differences are commonly referred 
to as timing differences.

If we collect more than the allowed level of revenue, 
the balance must be returned to customers in 
subsequent periods, and if we collect less than the 
allowed level of revenue we may recover the balance 
from customers in subsequent periods. In the US, 
a substantial portion of our costs are pass-through 
costs (including commodity and energy efficiency 
costs) and are fully recoverable from our customers. 
Timing differences between costs of this type being 
incurred and their recovery through revenue are also 
included in timing.

In the UK, there was a cumulative under-recovery of 
£177 million at 31 March 2015 (2014: under-recovery 
of £83 million). All other things being equal, the 
balance will start to be recovered from customers 
in the year ending 31 March 2016.

In the US, cumulative timing over-recoveries at 
31 March 2015 were £150 million (2014: £117 million 
over-recovery). The majority of that balance will be 
returned to customers next year.

In addition to the timing adjustments described 
above, as part of the RIIO price controls in the UK, 
outperformance against allowances as a result 
of the totex incentive mechanism, together with 
changes in output-related allowances included 
in the original price control, will almost always be 
adjusted in future revenue recoveries, typically 
starting in two years’ time.

Our current IFRS revenues and earnings include 
these amounts that will need to be repaid or 
recovered in future periods. Such adjustments 
will form an important part of the continuing 
difference between reported IFRS results and 
underlying economic performance based on our 
regulatory obligations.

For our UK regulated businesses as a whole, 
regulated revenue adjustments totalled £174 million 
in the year (2013/14: £106 million). This is based 
on our estimates of: work carried out in line with 
allowances; in expectation of future allowances; or 
work avoided altogether – either as a result of us 
finding innovative solutions or of the need being 
permanently removed.

In the US, accumulated regulatory entitlements 
to future revenue net of over- or under-recoveries 
amounted to £1,528 million at 31 March 2015 
(2014: £1,024 million). These entitlements cover a 
range of different areas, with the most significant 
being environmental remediation and pension 
assets, as well as deferred storm costs.

All regulatory entitlements are recoverable (or 
repayable) over different periods, which are agreed 
with the regulators to match the expected payment 
profile for the liabilities. As at 31 March 2015, these 
extend until 2071.

Major storms
Despite the very cold winter across much of the US 
including record snowfall in parts of New England, 
there were no major storms in 2014/15 or 2013/14.

Strategic ReportNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Our people
If we are to achieve our strategic objectives, we need to 
make sure our employees have the right skills and capabilities. 

Safeguarding the future 
There is a significant skills challenge facing the 
engineering profession in the UK. Research by 
EngineeringUK has highlighted a need for 1.8 million 
engineers, technicians and crafts people over the 
period 2012–2022. Around 60% of all new jobs in this 
period will need science, technology, engineering 
and maths (STEM) qualifications, yet not enough 
school children succeed in these areas. 

There is a similar challenge in the US where the 
number of scientists and engineers needed to 
meet growth and net replacement needs between 
2012 and 2022 is 2.3 million, including 1.2 million 
in the computer occupations and more than 
540,000 engineers.

We are helping schools, parents and children see 
engineering as a modern, dynamic, desirable career 
with a great future. Our employees act as education 
ambassadors who volunteer their time for a range 
of activities in the classroom and at science and 
engineering fairs, most notably on STEM enrichment, 
careers education and work experience programmes. 

Our careers education programmes in the UK 
include Careers Lab, an initiative we developed 
that was taken up by the charity Business in the 
Community in November 2014. It links working 
professionals from a range of sectors with schools to 
bring the world of work to life for secondary school 
children. A further initiative is the ‘Engineer Your 
Future’ exhibition at London’s Science Museum, 
which opened in December 2014 and explores 
engineering challenges through interactive games 
and digital experiences. 

During 2014/15, we have expanded our residential 
work experience programme (balanced 50/50 
between girls and boys) to include a non-residential 
programme for students aged 16–19 who are in 
sixth form or college and do not have an existing 
relationship with an employer.

This year, we invested nearly £900,000 in our 
education outreach, bringing benefits to 70 schools 
and more than 9,000 students who receive at least 
one hour of STEM/careers experience with our 
education ambassadors. We expect this to grow 
considerably in the UK through Careers Lab. 

In the US, we continue to partner with seven 
local community colleges to deliver energy utility 
technology training programmes, designed to 
equip people for jobs in the energy industry. These 
programmes currently focus on future line workers. 
We plan to expand them to include technical skills 
for the gas industry.

We are continuing our partnership with the Center 
for Energy Workforce Development on its ‘energy 
industry fundamentals’, and we work with veterans 
through the US Troops to Energy Jobs programme. 
This is designed to help veterans make the transition 
from military service to the energy/utility industry. 

We completed the fifth year of our Engineering 
Pipeline Program. This is a developmental 
programme designed to inspire promising 
students to become engineers and provide them 
an opportunity for fast tracked employment with 
National Grid. 

We are working with the State University of New York 
and its network of colleges and universities. The aim 
is to prepare students for careers in the energy and 
utilities industry by improving the educational 
opportunities available to them. We expect this 
partnership to increase the volume of qualified 
entry-level candidates looking to join National Grid.

Our US work experience opportunities include six to 
eight week summer internships for college students, 
so they can gain work experience with National Grid. 
A number of these interns start their journey into the 
energy industry through our Engineering Our Future 
programme and go on to join our Company. 

In the UK, we offer summer internships and also 
12 month industrial placements to undergraduates 
in their penultimate year. These programmes offer 
students the opportunity to experience the culture, 
working and ethical practices of National Grid before 
they make the all-important decision to join the 
organisation as graduates. 

Building skills and expertise 
During 2014/15, we have worked on boosting 
the capabilities of our employees in the areas of 
Performance Excellence (see page 27), stakeholder 
engagement, customer focus and contract 
management. We see these capabilities as being 
crucial in helping us improve our performance and 
meet regulatory and customer expectations.

More than 900 employees have attended our 
Performance Excellence programmes; more than 
650 employees have attended our stakeholder 
engagement and customer focus programmes; and 
around 250 employees have attended our contract 
management programmes. 

Our executive team and senior leaders in the UK 
and US are participating in a programme to develop 
performance leadership skills. To prepare for our 
future engineering skills needs, we have built a 
T-pylon development facility at our Eakring learning 
centre in the UK.

We remain committed to investing in our people, 
providing the training and other support necessary 
for them to build, maintain and operate our networks 
safely and reliably, and this year we provided more 
than one million learner hours of training across our 
UK and US businesses.

Strategic ReportPromoting an inclusive and diverse 
workforce
We aim to develop and operate our business with an 
inclusive and diverse culture, with equal opportunity 
to all in recruitment, career development, training 
and reward. This applies to all employees regardless 
of race, gender identity, nationality, age, disability, 
sexual orientation, religion and background. Our 
policies support the attraction and retention of the 
best people, improve effectiveness, deliver superior 
performance and enhance our success.

Health and wellbeing 
Among our programmes for 2014/15 we have 
worked to address the stigma and discrimination 
associated with mental health. We signed the UK 
Government-led ‘Time to Change’ pledge and have 
trained a further 92 employees in mental health

Our UK regulated businesses delivered a strong 
financial performance in the second year of RIIO. We 
aim to create value for our stakeholders by focusing 
on performance and making sure our processes 
are as efficient as they can be (see ‘Performance 
Excellence’ below). Savings generated in the first 
two years of RIIO will reduce future customer bills 
by around £200 million. 

We have also established a new organisational 
structure to give stakeholders a clearer picture of 
how our activities are organised and delivered.

We have responded to concerns about the cost of 
energy and the security of the UK’s energy supply. 
In evidence to parliamentary inquiries we have 
explained our role, the services we provide and what 
those services cost. We have also been working with 
stakeholders in Europe to plan for the future impact 
of European Union energy policy on our business.

Our non-regulated businesses have been focused 
on getting the best value from our existing portfolio 
and exploring opportunities for future growth. 
For further information see page 36. We have also 
signed two new interconnector agreements: with 
Elia, the Belgian Transmission System Operator, 
for an electricity interconnector between the UK 
and Belgium; and with Statnett, the Norwegian 
Transmission System Operator, for NSN Link, the 
first interconnector between the UK and Norway. 
These agreements signal the start of the construction 
phases of these projects. 

Principal risks
As described in the Internal controls and risk 
management section (pages 38 to 41), we identify, 
monitor and manage risks at various levels within our 
Company. The key risks our UK business faces are 
organised into a UK regional risk profile which is 
regularly reviewed by UK senior leadership. The main 
risk themes currently featured in this profile are:

•  the risk of changes to the complex political and 
regulatory agenda for UK and European energy 
policy development and their potential implications 
for our business;

•  challenges associated with making sure the data 

required to deliver business processes and 
regulatory requirements is complete, accurate 
and consistent; 

•  the impact of changes in our business structure 

and processes on our ability to continue to 
perform under RIIO; and

•  continued management of safety, security and 

network resilience.

System Operator (SO) progress
Our SO role is described on pages 08 and 11.

The UK faces tightening capacity margins between 
supply and demand for the next three years. Helping 
the market to make the right decisions to maintain 
security of supply has been an important theme in 
our role as SO during 2014/15. 

Following a number of generation plant outages over 
the winter, the two new balancing services developed 
to provide additional reserves were tendered as a 
precaution. Although these additional reserves were 
not used this year, they have also been tendered to 
procure additional capacity for winter 2015/16 when 
margins are predicted to tighten further.

We have continued to work with stakeholders 
to develop and implement EMR. We completed 
pre-qualification and auctions for the Capacity 
Market and the Contract for Difference (CfD) feed-in 
tariff regime. The capacity market auction this year 
procured additional capacity ready for the first year 
of delivery in 2018/19. Contracts were signed with 
25 applicants following the first auction for CfD. 

We have led the development of changes to the gas 
transmission regulatory framework that will help 
customers plan their long-term projects through an 
improved way of reserving capacity. We have also 
developed a new framework that adds current 
system operation knowledge to long-term 
predictions about the future energy landscape. 
This helps us plan for the right services and 
products to operate the system in the future. 

Priorities for the year ahead
Our role as SO is set to evolve during 2015/16, 
following the conclusion of Ofgem’s Integrated 
Transmission Planning and Regulation project. 
As part of this, the SO is expected to undertake a 
number of new advisory roles. We have a long track 
record in successfully managing potential conflicts 
of interest from our SO role and will work closely 
with Ofgem to make sure this continues.

We will also be engaging further with the industry, 
aiming to increase opportunities for demand-side 
participation within the GB market.

Performance Excellence
Performance Excellence is an approach that will help us to achieve our Company objectives by looking 
for improvements to all of our processes. It aims to save time and make us more efficient so we can 
deliver better value for our customers and stakeholders – from new ideas that improve processes, to 
introducing equipment that does things more effectively. For example, in our UK Gas Distribution business, 
regional Performance Excellence teams are working with our operational teams to identify their common 
challenges and find the right solutions. As a result we have introduced a new helpdesk service for our 
Gas Distribution field force. This new service means technology problems are resolved more quickly, 
helping them to be more productive and better meet customer needs. See page 35 to read more about 
Performance Excellence in the US.

UK Electricity Transmission

In focus: 

Electricity transmitted 
across our network

291,041
GWh

What we do
We own the electricity transmission 
system in England and Wales. Our 
networks comprise approximately 
7,200 kilometres (4,470 miles) of 
overhead line, 1,500 kilometres 
(932 miles) of underground cable 
and 336 substations.

Market context
Although demand for electricity is generally increasing 
around the world, in the UK it is expected to remain 
broadly flat over the next five to 10 years.

Changes in the sources and characteristics of 
generation connecting to our network, such as wind 
and nuclear generation, mean we need to respond 
by developing the way we balance and operate 
our network to accommodate these sources.

Over the last two years, some generators have 
delayed their connection dates to the network 
and this means our future investment profile for 
electricity transmission is flatter than in previous 
years. However, we are ready to respond to 
connection dates when we need to. We will 
continue to renew our network to deliver the 
network reliability our customers require as 
efficiently as possible.

What we’ve achieved during 2014/15
The full tunnel network on our London Power Tunnels 
project has been completed, and the remaining 
works programme is forecast to complete ahead 
of schedule and under budget. We have also 
completed the development of a £164 million asset 
replacement and customer connection project 
for Wimbledon.

We made progress on substation and cable 
construction work for several new Network Rail 
connections, as well as Crossrail connections in 
London. These connections are required to support 
the national railway electrification programme from 
2015 to 2017.

We achieved a significant engineering milestone, 
installing the first ever series compensation device 
on the UK network. This device, which adds capacity 
to a transmission circuit, can increase power flows 
from Scotland. With both National Grid and Scottish 
Power series compensation in service, the Scotland-
England boundary capacity is expected to increase 
by 1 GW.

We have continued to develop the innovative T-pylon 
and are considering where it could be offered 
alongside other connection options when developing 
new transmission circuits. The first T-pylon has been 
installed at our Eakring training facility.

Our Visual Impact Provision (VIP) project gathered 
pace. Our policy to make use of the £500 million 
allowance under RIIO to mitigate the visual impact 
of our overhead lines in National Parks and Areas 
of Outstanding Natural Beauty was agreed with 
Ofgem. A stakeholder advisory group, including 
representatives of organisations with a national focus 
on our natural heritage, is helping us choose which 
transmission lines should be prioritised and how the 
fund should be allocated.

We agreed an RPI-linked bank loan facility of 
£1.5 billion with the European Investment Bank (EIB). 
This is the largest ever single loan by the EIB and is 
now available to fund capital investment in National 
Grid Electricity Transmission plc.

We also deployed new tools and systems to our field 
workforce, winning the Mobile Innovation category 
at the SAP UK Quality Awards. 

Priorities for the year ahead
Safety: Make sure our suppliers and employees 
manage their safety performance when working 
near our transmission assets. This includes seeking 
evidence that they are using effective safety 
management systems. 

Maintenance: Establish a programme to change the 
way we plan and deliver all work on our assets by 
balancing risk, performance and delivery costs. 

Hinkley Point C connection: Continue to progress 
the regulatory submissions needed for the Hinkley 
Point C connection project to secure the funding 
for delivery. 

Visual Impact Provision: Through our VIP project 
we will identify the final locations where the visual 
impact of our networks will be reduced. 

Data and technology: Continue to improve how 
we define and capture the network data that 
helps us make better decisions on our assets 
and respond more quickly to customer demand 
for new connections.

Strategic ReportUK Gas Transmission

In focus: 

40 times

The gas national 
transmission system 
operates at pressures 
up to 94barg – around 
40 times the pressure 
of an everyday car tyre. 

What we do 
We own and operate the gas 
national transmission system in 
Great Britain, with day-to-day 
responsibility for balancing supply 
and demand. Our network 
comprises approximately 7,660 
kilometres (4,760 miles) of high 
pressure pipe and 24 compressor 
stations. In 2014/15 the gas 
throughput across the system 
was over 80 billion cubic metres. 

Market context
The UK’s gas market and sources of gas are 
changing. Domestic demand has fallen over the last 
five years and a significant increase is not expected in 
future years. The UK continental shelf (UKCS) now 
makes up less than half our total gas supply, with

the remainder coming from Norway, continental 
Europe, or further afield via shipped imports of LNG. 

Overall, supply capacity now exceeds peak 
demand by more than 25%, giving our customers 
significant flexibility over which sources of gas they 
choose to meet demand. Newer sources of supply, 
such as LNG importation terminals and storage 
sites, can respond to demand more quickly than 
traditional UKCS supplies. Our network therefore 
needs to be able to respond to changing day-to-day 
supply and demand patterns.

We also need to prepare for an uncertain energy 
landscape in the long term. UK reliance on imported 
gas supplies will vary depending on the level of gas 
supply from the UKCS and the development of 
indigenous gas sources. 

We are working closely with our customers and 
stakeholders to meet these operational challenges. 
We are focused on continuing to develop our 
network and services to meet their needs safely, 
reliably and efficiently.

What we’ve achieved in 2014/15
We delivered a strong safety performance, 
particularly in our operations business where we 
have achieved 24 months (from April 2013) without 
a single lost time injury suffered by our employees 
or contractors.

We reached record levels of compressor availability 
in our network. Operational availability was at 100% 
several times during the winter, with an average of 
96%. This is a rise of 7% on the average for winter 
2013/14. It follows targeted investment in our fleet 
of compressors and improvements to our planning 
process, maintenance and repair methods.

We received £5.7 million from Ofgem following a 
successful bid in the Network Innovation Competition 
for designing and building a robotic device that can 
inspect below-ground pipework at high pressure 
installations. The device will help us to better assess 
asset condition, so we can focus expenditure where 
it is needed, benefiting gas consumers. 

To meet the stricter environmental limits imposed by 
the Industrial Emissions Directive (IED), our larger gas 
turbines will need modifying or replacing. We have 
sought feedback from our stakeholders on the 
impact of the IED, adapting our proposed solutions 
in response. This has helped us develop investment 
options to make sure the network can meet the 
future needs of our customers and operate as 
efficiently as possible.

Priorities for the year ahead
Safety: Sustain and improve our safety performance 
by implementing a new safety culture improvement 
programme across UK Gas Transmission.

Reliability: Build on improvements we have made 
this year in compressor availability, extending this 
across other critical assets in our network to further 
improve the service we deliver to our customers. 

Efficiency: Continue improving end-to-end 
processes and deliver greater value for customers 
by being more efficient. Where we create additional 
capacity, we will look to insource some maintenance 
work and increase specialist pipeline services 
for customers.

Innovation: Use the innovation opportunities 
available through the Network Innovation Competition 
and Network Innovation Allowance funding. This 
will help us to create value for customers and the 
industry, and to achieve our RIIO-T1 commitments.

Emissions compliance projects: Continue work on 
existing emissions compliance projects and secure 
funding for continued works over the remainder of 
the RIIO-T1 period and beyond.

What we do
We own and operate four gas 
distribution networks comprising 
approximately 131,000 kilometres 
(82,000 miles) of pipeline. We 
transport gas from the national 
transmission system to around 
10.9 million consumers on behalf 
of 37 shippers. 

Market context
We manage our networks to keep our customers 
safe and warm. We are incentivised through RIIO 
to operate efficiently and deliver services that our 
customers and stakeholders value. 

Ofgem is able to make comparisons across all 
eight networks. It establishes outputs they are 
expected to deliver so that we all maintain a safe 
and reliable network; make a positive contribution to 
sustainability and protect the environment; provide 
connections to supply new consumers and support 
new gas entry points into the network; meet their 
social obligations; and provide an agreed standard 
of service to consumers and other stakeholders.

We collaborate with the industry on issues that are 
common to all networks and customers, such as 
innovation, safety and the future of networks to 
deliver outcomes that customers value.

Gas remains an important part of the current and 
future energy mix and we are working with our 
customers and stakeholders to develop our 
networks to accommodate gas from new sources, 
such as bio-methane.

What we’ve achieved during 2014/15 
We believe we are making progress towards our 
ambition to be the best gas distribution business in 
Britain by 2017. We understand where we need to 
focus to deliver our RIIO outputs and deliver better 
customer service.

We are investing in our networks to make sure we 
meet customer and stakeholder needs. This includes 
replacing approximately 1,450 kilometres of old metal 
pipelines with more durable materials as part of our 
mains replacement programme developed with the 
HSE and Ofgem. In London, we have replaced 
around 300 kilometres of iron mains, including 
projects in Battersea and around the City.

However, against a backdrop of increased customer 
complaints across the industry, our volumes have 
also increased. To help improve this, a particular 
focus this year has been on simplifying the process 
for customers who want to connect to our networks 
by improving our website experience and providing 
them with a single point of contact.

We have invested in new mobile technology for our 
field workforce to increase productivity and provide 
our supervisors with real-time information. This has 
also helped improve employee engagement scores 
and the desire to drive better outcomes for our 
customers; our field workforce now compares 
favourably with industry benchmarks.

We have also completed ten commercial bio-
methane connections, more than any other UK gas 
distribution network, including the first 100% food 
waste plant and the first commercial sewerage 
connection with Severn Trent Water.

Overall, we have delivered successfully against 
our targets to deliver world-class levels of safety 
performance across our combined field workers and 
contractor workforce. In terms of cable strikes and 
injuries to members of the public, although we have 
missed our targets, we have increased our efforts to 
make improvements. We have also used innovative 
technology that has helped reduce excavation 
volumes, so we can minimise disruption. We have 
also been helping stakeholders such as landowners 
and the construction industry understand how we 
protect pipelines and how they can operate safely 
around them.

During 2014/15, we were recognised by Ofgem 
as the best performing gas distribution network in 
understanding our customer and stakeholder needs 
for the previous year. Our focus in this area has seen 
over 1,200 fuel poor customers benefiting from 
an alternative, more affordable method of heating 
their homes since we have connected them to our 
gas networks. 

Priorities for the year ahead
Improve our safety performance by further 
reducing cable strikes, injuries to members of the 
public and preventing third-party encroachment. 
This will continue to be an important area of focus.

Continue to use innovative technology to deliver 
better services that reduce the impact on customers’ 
bills and minimise disruption caused by our work. 

Improve our customers’ experience of planned 
replacement work projects by working with our 
partners to improve our processes, data capture and 
how we communicate and engage with our customers. 

Continue to work with government and industry 
on setting out the vision for the future role of gas in the 
UK’s energy mix and policies that support this role, 
while considering how domestic smart meters can 
create value for customers.

Motivate and equip our workforce with the 
tools and knowledge they need to deliver the 
services and outcomes our customers value, 
while increasing productivity.

Principal risks
As described in the Internal controls and risk 
management section (pages 38 to 41), we identify, 
monitor and manage risks at various levels within our 
Company. The key risks our US business faces are 
organised into a US regional risk profile which is 
regularly reviewed by the US senior leadership. The 
main risk themes currently featured in this profile are:

•  our ability to manage data integrity and systems 
improvements required to deliver core business 
processes and regulatory requirements;
•  our ability to recover costs through existing 

rate-making mechanisms and to influence the 
development of the future US utility business model; 

•  our ability to enhance our US business structure 
and end-to-end processes to support an evolved 
jurisdictional performance environment; and
•  safety performance and network reliability, 

security and resilience.

What we’ve achieved
During 2014/15, we delivered a solid performance 
and continued with high levels of investment in our 
networks. As described on pages 18 and 19, we 
achieved our reliability KPI targets but we still have 
work to do if we are to improve our customer 
satisfaction target scores.   

We finally completed the stabilisation work on our 
new enterprise resource planning system. This fixed 
a number of long-standing problems, such as 
inefficient payroll processing, which had previously 
required expensive manual interventions. Long term, 
the data we can produce with the new systems are 
an essential foundation to the future performance 
improvements and regulatory filings that we need 
for profitable growth in the US.

In 2010, the Massachusetts Department of Public 
Utilities (MADPU) approved a power purchase 
agreement between National Grid and Cape Wind 
for a proposed large-scale, offshore wind farm in 
Nantucket Sound. In 2014, Cape Wind did not satisfy 
certain critical milestone deadlines set out in the 
power purchase agreement and did not post 
collateral to extend the deadlines in the power 
purchase agreement. As a result, the power purchase 
agreement was terminated in January of 2015. We 
continue to believe the solution to New England’s 
energy challenge is a diversity of energy sources, 
which is why we support renewable projects 
consistent with our goal of reducing emissions 
while minimising the cost impact on our customers.

In a joint programme with Earth Networks, we 
purchased 55 Weatherbug stations to donate to 
our communities in Massachusetts, New York and 
Rhode Island. These stations provide customers 
with more localised weather information and we use 
them to better prepare for and respond to storms. 
They also contribute to STEM education in giving 
free real-time local weather data to schools and 
emergency responders.

We continue to invest more in reinforcing the 
electricity distribution system and also in replacing 

34

gas mains. The NYPSC approved $414 million gas 
infrastructure investment in Long Island to speed up 
the replacement of ageing pipe and extend the use 
of natural gas to more customers. 

Our Sustainability Hub 
in Worcester, MA.

The NYPSC also published the results of the 
regulatory audit of our New York gas companies. 
These audits are a regular feature of the New York 
regulatory process. The audit was broadly 
supportive of our performance and structure and, 
as is usual, made some recommendations for 
further improvement. It specifically recommended 
stronger local leadership and a number of more 
cost-effective and customer-focused operational 
enhancements. We have responded with an 
implementation plan to provide these benefits 
on behalf of New York customers.

Last year, regulatory audits in New York also 
identified an unacceptable number of violations 
of the regulations relating to our gas operations. 
To improve our regulatory compliance performance, 
we are investing in compliance monitoring systems, 
adding compliance personnel, and enhancing our 
training and safety protocols.

Our regulators and customers have heightened 
expectations around safety and compliance for all 
gas utilities. We are committed to doing everything 
we can to meet their expectations and making 
sure sufficient resources are dedicated to support 
this priority. 

Building on performance improvements in 2013/14, 
we saw a reduction in safety incidents in 2014/15. 
In the past year, there has been a 7% reduction in 
the number of injuries requiring medical attention 
and a 26% reduction in the number of cases 
requiring employees to stay out of work. These 
reductions result from programmes and initiatives 
based on risk areas, improved incident investigations 
and root cause analysis. There is still much work to 
do as we strive for zero injuries. Soft tissue injury 
prevention, safety observations, road traffic collisions 
and slips, trips and falls will remain a focus for us in 
2015/16.

Each of our jurisdictions has projects under way to 
develop economic and environmental health in three 
ways: by driving economic growth; providing cleaner 
energy; and advancing innovative technologies. 
We have highlighted some of our 2014/15 
achievements below. 

Massachusetts
We are preparing to file a grid modernisation plan – a 
blueprint for the modernisation of the electric system 
– with MADPU in August 2015.

We have announced plans to build, own, and operate 
an additional 16 MW of solar generation, bringing 
total solar capabilities in the state to 21 MW.

As of late 2014, we had installed 39.9 miles of new 
gas mains and added more than 8,400 new natural 
gas customers.

Strategic ReportNew York
We are helping to shape new energy policy in the 
state through our REV filings. REV is aimed at 
transforming the electricity energy industry and 
regulatory practices in New York State. 

We are adding new electricity capacity and 
infrastructure to RiverBend, Buffalo, a former 
industrial brownfield that is bringing growth and jobs 
to the state. Companies including Solar City and 
Soraa will bring investment, much needed jobs, 
and new and advanced energy technologies that 
could make this region a hub for energy development 
regionally, nationally and internationally.

We are negotiating a power purchase agreement 
with ReEnergy under which we intend to purchase 
excess energy from a 55 MW biomass generating 
facility at Fort Drum in Watertown. This will be the 
largest renewable energy project in the history of the 
US Army. 

We have begun a two year plan to replace ageing 
pipes and expand the use of natural gas on Long 
Island and the Rockaway Peninsula to more than 
20,000 new customers. This accelerates the 
replacement of ageing pipes from the current 50-mile 
requirement to 95 miles by 2016. 

We are partnering with New York City to accelerate 
the phase out of heavy oils in around 800 buildings. 
Since the programme’s launch in 2011, we have 
converted over 500 heavy oil buildings. We continue 
our efforts to convert the few remaining clean heat 
eligible buildings on Staten Island.

Rhode Island
The $93 million Aquidneck Island Reliability Project, 
known as OnIsland, will bring more reliable power 
to the nearly 32,000 homes and businesses in 
Portsmouth, Middletown, and Newport. The project 
includes two substations, reconfiguration of two 
transmission lines, local distribution work, and 
retirement of five substations on the island.

We have been working with Toray Plastics, one of the 
largest employers in the state, on customised energy 
solutions. In 2014 the company opened its second 
cogeneration system at its 70-acre campus in North 
Kingstown and we supported them with an energy 
efficiency incentive of $15.9 million.

We are building a new state-of-the-art substation 
to replace the existing ageing infrastructure at the 
current South Street Substation, which powers 
downtown Providence. This coincides with a 
$206 million redevelopment of South Street Landing 
that will turn the vacant former South Street Power 
Station into teaching and administrative space for 
Brown University, Rhode Island College and the 
University of Rhode Island.

FERC
We are part of a joint venture to form New York 
Transco. This aims to construct, own, and operate 
incremental electric transmission assets in New York 
State to improve reliability and reduce congestion. 

It is initially pursuing five projects that support public 
policy objectives and provide broad-based benefits 
across the state. New York Transco filed with FERC 
in December 2014 for rate recovery and cost 
allocation for proposed transmission projects, 
estimated at $1.7 billion.

We have joined Spectra Energy’s $3 billion proposed 
Access Northeast pipeline project that aims to 
significantly increase natural gas capacity to 
generators in New England. Our three New England 
electric distribution companies have established 
memoranda of understanding with project developers 
to explore the development of an innovative tariff that 
would enable them to take capacity from the pipeline 
and release it into the market as needed to mitigate 
wholesale electricity price spikes. 

In December 2014, we announced we had joined 
forces with Anbaric Transmission to develop 
large-scale HVDC transmission projects to deliver a 
combination of domestic wind energy and Canadian 
hydropower to New England load centres. We are 
currently developing a 1,000 MW hybrid land and sea 
HVDC project from northern Maine to Greater Boston 
and a 400 MW underground HVDC project from 
upstate New York to Vermont under Lake Champlain.

We are working with Eversource Energy in 
implementing the Greater Boston and New Hampshire 
Solution to address critical grid reliability needs. 
We will be investing approximately $190 million 
in the Solution for new infrastructure in southern 
New Hampshire, northern Massachusetts, and 
the Greater Boston area. We expect the Solution 
to be in service by 2019.

Priorities for the year ahead
We continue our Connect21 journey with these four 
priorities for 2015/16: Performance Excellence; local 
operating model; talent and capabilities; and future 
energy networks. 

Performance Excellence: We will improve the way we 
work as teams to become more efficient, innovative, 
and responsive to our customers’ needs in end-to-
end processes that include: meter to cash; emergency 
response; deliver gas and electric; maintain gas and 
electric; and operate gas and electric. 

Local operating model: We will continue to drive 
greater accountability and customer service by 
delivering the services and obligations expected by 
the 14 operating companies and four jurisdictions 
that comprise our US business – at a cost and 
performance level agreed upon by each jurisdiction’s 
management team.

Talent and capabilities: We will provide employees 
with the tools and resources they need to achieve the 
performance measures required by our customers 
and shareholders. 

Future energy networks: We will update and create 
new electricity and gas networks through design, 
operational, and regulatory innovations.

Grain LNG 
Grain LNG is one of three LNG importation facilities 
in the UK. It operates under long-term contracts with 
customers and provides importation services of ship 
berthing, temporary storage and re-gasification in to 
the national transmission system. 

This year, we have continued to explore developments 
to our LNG services to increase revenue, including 
the potential to offer ship reloading. 

We have started a ship cool-down service. This 
process helps ships that have been out of service 
or having maintenance to reload full LNG cargo. 

In 2015/16, we will also commission and launch our 
LNG road tanker loading facility. This will provide 
tankered LNG to off-grid customers and operators 
of heavy goods vehicles. 

Interconnectors 
The England-France interconnector (IFA) is a 
2,000 MW HVDC link between the French and 
British transmission systems with ownership shared 
between National Grid and Réseau de Transport 
d’Electricité. The interconnector’s availability 
continued to improve this year following a significant 
valve replacement programme. Average availability 
for 2014/15 was 90.62%, up from 83.84% in 2013/14. 
A substantial proportion of the flow continues to be 
in the import direction, from France to Great Britain.

BritNed is a joint venture between National Grid and 
TenneT, the Dutch transmission system operator. 
It owns and operates a 1,000 MW HVDC link between 
England and the Netherlands. As with IFA, a substantial 
proportion of the flow is in the import direction from 
the Netherlands to Great Britain.

Throughout 2014/15, both IFA and BritNed have 
operated as part of the North West Europe market 
region. The creation of this region is part of the 
ongoing development of the EU’s Internal Energy 
Market. IFA and BritNed have entered this region 
voluntarily ahead of the introduction of new EU-wide 
rules for cross-border electricity trading. 

IFA and BritNed are also involved in the next phase of 
this regional market that will cover the intraday market 
timescale (currently it only covers the day ahead 

timescale). Intraday markets help market participants 
adjust their positions better over short time periods.

Metering
National Grid Metering (NGM) provides installation 
and maintenance services to energy suppliers in the 
regulated market in Great Britain. It maintains an 
asset base of around 14.1 million domestic, industrial 
and commercial meters.

The domestic traditional gas metering business 
continues to operate in its role as the National 
Metering Manager, pending the start of the smart 
metering mass roll-out. This role means customers 
have a point of contact if they require a meter up until 
the start of the smart metering roll-out. Tariff caps 
agreed with Ofgem as part of this role, which took 
effect on 1 April 2014, will continue to apply until at 
least the end of the transition to smart metering.

Customer satisfaction scores for NGM remain 
positive for both its domestic, and industrial and 
commercial businesses, but we continue to work 
with our customers on areas for improvement. In 
our industrial and commercial business we have 
implemented new software that allows remote 
customer self-serve access for some services 
and is expected to improve efficiency. We are also 
responding to the rapidly changing non-domestic 
sector by exploring additional products and services. 

UK Property 
National Grid Property is responsible in the UK for the 
management, clean-up and disposal of surplus sites, 
most of which are former gas works. During 2014/15, 
we entered into a joint venture with the Berkeley 
Group, known as ‘St William’, to develop surplus 
land for residential use in London and the South East. 
We have also sold 42 sites and exchanged on several 
high-profile land disposal agreements with joint venture 
partners. Our holder demolition and contaminated 
land clean-up programmes are progressing well, 
and we are in the process of retendering our estate 
management outsourcing agreement.

Xoserve 
Xoserve delivers transactional services on behalf of 
all the major gas network transportation companies 
in Great Britain, including National Grid. Xoserve 
is jointly owned by National Grid, as majority 
shareholder, and the other gas distribution network 
companies. Xoserve celebrated its 10 year 
anniversary as a company on 1 May 2015. 

US non-regulated businesses 
Some of our US businesses are not subject to 
state or federal rate-making authority. These include 
interests in some of our LNG road transportation, 
some gas transmission pipelines (our minority equity 
interests in these are not regulated) and certain 
commercial services relating to solar installations, 
fuel cells and other new technologies.

Corporate activities
Corporate activities comprise central overheads, 
Group insurance and expenditure incurred on 
business development.

Strategic ReportPutting our 
surplus land 
to good use

Connecting to life:

St William Homes
In November, we announced the creation of 
St William Homes LLP, a joint venture with the 
Berkeley Group. St William will transform acres 
of former industrial land owned by National Grid 
in London and the UK’s South East region, into 
homes and amenities for local communities. 

The sites, like the one shown here at Battersea, 
South West London, have potential to provide 
over 14,000 homes over the next 10–15 years. 
In its first phase, St William aims to regenerate 
84 acres of land, develop more than 7,000 new 
homes, including over 2,000 affordable homes. 
Development at this scale would also deliver 
5,500 jobs, two new schools and 22 acres of 
public open space.

At our Battersea Gasholder site, we have 
recovered and donated decorative, heritage 
crests to our neighbours, the Battersea Dogs 
and Cats Home, shown above.

Strategic ReportInternal control and risk management
The Board is committed to protecting and enhancing our reputation and assets, 
while safeguarding the interests of our shareholders. It has overall responsibility 
for the Company’s system of risk management and internal control. 

National Grid is exposed to a variety of uncertainties 
that could have a material adverse effect on the 
Company’s financial condition, our operational 
results, our reputation, and the value and liquidity 
of our shares. 

The Board oversees risk management, and, as 
part of this role, it reviews the main elements of our 
process and sets and monitors risk appetite. Risk 
appetite establishes the amount of uncertainty the 
Company may seek or accept at any given time 
when pursuing our strategic objectives.

The Board regularly reviews our internal controls 
and risk management processes. This year specific 
consideration was given to the guidance in the new 
UK Corporate Governance Code 2014 (the New 
Code) which applies to the Company in the next 
fiscal year and refinements to our processes will be 
introduced, as appropriate, over the coming year.

Risk management approach
Our Company-wide corporate risk management 
process provides a framework through which we can 
consistently identify, assess and prioritise, manage, 
monitor and report risks, as shown in the diagram 
below. The process is designed to support the 
delivery of our vision and strategy as described 
on pages 14 and 15. 

Our process involves a continuous cycle of bottom-
up review and reporting and top-down review 
and feedback. 

All our business functions participate in the bottom-
up risk management process. They identify the main 
risks to achieving their objectives and the actions 
being taken to manage and monitor them. They 
assess each risk by considering the potential ‘worst 
case credible’ financial and reputational impacts 
and how likely the risk is to materialise. The risks we 
identify are collated in risk registers and are reported 
at functional and regional levels of the Company. 
The risk registers also describe the adequacy of our 
existing risk controls.

An important feature of our risk management 
process is that each business function owns and 
is responsible for managing its particular risks. 
A central risk management team acts as an advisory 
function and also provides independent challenge 
and review. This team partners with the business 
functions through nominated risk liaisons and 
collaborates with assurance teams and specialists, 
such as internal audit and compliance management, 
to sense check risk information.

Regional senior management regularly review and 
debate the outputs of the bottom-up process and 
agree the prioritisation of the risks. The main risks for 
the UK and US businesses are highlighted in regional 
risk profiles and reported to the Chief Executive 
through quarterly performance reports. An overview 
of current risk themes for the UK and US businesses 
is provided on pages 27 and 34 respectively. 

Our main strategic uncertainties or ‘principal risks’ 
for the Company are developed through top-down 
discussions with the Executive leadership team. 
These risks are reported and debated with the 
Executive Committee and Audit Committee every 
six months. 

The Board participates in an annual risk workshop 
to make sure that the principal risks remain closely 
aligned to our strategic aims and that no important 
risks (or combination of risks) are being overlooked. 
In addition, the Board considers emerging risks 
(uncertainties that are still developing and sit outside 
the principal risks profile) together with our strategy 
team’s annual long-term update.

The outcomes from each level of the risk review 
process are fed back to the relevant teams and 
incorporated as appropriate into the next cycle 
of our ongoing process as shown below.

Strategic Report 
 
 
 
Our principal risks
Accepting that it is not possible to identify, anticipate or eliminate 
every risk that may arise and that risk is an inherent part of doing 
business, our risk management process aims to provide 
reasonable assurance that we understand, monitor and manage 
the main uncertainties that we face in delivering our objectives. 

This includes consideration of inherent risks, which exist because 
of the nature of day-to-day operations in our industry, and financial 
risks, which exist because of our financing activities. An overview 
of the key inherent risks we face is provided on pages 173 to 176, 

as well as an overview of our key financial risks, which is 
incorporated within the Notes to our consolidated financial 
statements on pages 94 to 158. 

Our corporate risk profile contains the principal risks that the Board 
considers to be the main uncertainties currently faced by the 
Company as we endeavour to achieve our strategic objectives. 
An overview of these risks is provided below, together with 
examples of the relevant controls and current mitigating actions 
we are taking.

Drive growth 

Failure to identify and execute the right 
opportunities to deliver our growth strategy.

Failure to sufficiently grow our core business 
and have viable options for new business 
over the longer term would negatively affect 
the Group’s credibility and jeopardise the 
achievement of intended financial returns. 

Our ability to achieve our ambition for 
growth is subject to a wide range of 
external uncertainties, including the 
availability of potential investment targets 
and attractive financing and the impact 
of competition for onshore transmission 
in both the UK and US; and internal 
uncertainties, such as the performance 
of our operating businesses and our 
business planning model assumptions.

•  We regularly monitor and analyse market conditions, 

competitors and their potential strategies, the advancement 
and proliferation of new energy technologies, as well as 
the performance of our Group portfolio. We are also looking 
to access new sources of finance and capabilities 
through partnering.

•  We have internal processes for reviewing and approving 

investments in new businesses, disposals of existing ones and 
organic growth investment opportunities. These processes are 
reviewed regularly to make sure our approach supports our 
short- and long-term strategies. We undertake due diligence 
exercises on investment or partnering opportunities and carry 
out post-investment reviews to make sure we learn lessons for 
the future.

Engage  
externally

Inability to influence future energy policy. 

•  In the UK, we are continuing to work closely with DECC 

Policy decisions by regulators, governments 
and others directly affect our business. 
We must engage widely in the energy 
policy debate, making sure our position 
and perspective help to shape future 
policy direction.

and Ofgem on Electricity Market Reform (EMR) plans. We 
successfully implemented the first Capacity Market Auction 
and Contracts for Difference Allocation process and are 
working with the Regulator to finalise the enduring EMR 
Business Plan to ensure we continue to deliver value under 
RIIO. We continue to maintain strong relationships with 
government, engage in consultations, and develop 
comprehensive stakeholder communication plans. The Board 
is also continuing to monitor the increasing public debate 
around the cost, availability, security and sustainability of UK 
energy supplies. 

•  In the US, we are engaging our external stakeholders about 
the role of the utility company of the future, under the banner 
of Connect21. We believe this conversation will help shape the 
regulatory and fiscal regime in the US in the future. Regulatory 
proceedings related to utility of the future have been launched 
in New York (Reforming the Energy Vision) and Massachusetts 
(Grid Modernization) and our Connect21 aligns well with them. 
We are continuing to strengthen our jurisdictional focus and 
are improving our rate case filing capabilities so our businesses 
can continue to earn a fair and reasonable rate of return. 
Our rate filings include structural changes where appropriate, 
such as revenue decoupling mechanisms, capital trackers, 
commodity-related bad debt true-ups and pension and 
other post-employment benefit true-ups, as described on 
pages 169 and 172. 

•  We maintain and monitor a reputation ‘watch list’ at both 
Company and regional levels to support awareness and 
proactive management of issues that could cause us 
reputational harm.

Engage our  
people

Inability to secure the business capacity, 
appropriate leadership capability and 
employee engagement levels required 
to deliver our vision and strategy.

It is through the high-quality work of our 
employees that we will achieve our vision, 
respond to the changing needs of our 
stakeholders and create a competitive 
advantage. Obtaining and fostering an 
engaged and talented team that has 
the knowledge, training, skills and 
experience to deliver on our strategic 
objectives is vital to our success. We must 
attract, integrate and retain the talent we 
need at all levels of the business. 

Failure to achieve levels of financial 
performance required to meet regulatory 
requirements.

The Group operates under a number of 
regulatory regimes and we must maintain 
the performance levels required. Failure to 
achieve the agreed returns could damage 
our reputation and threaten future growth 
opportunities and regulatory arrangements.

Failure to deliver appropriate information 
systems and data integrity. 

The Company is increasingly reliant on 
technology to support and maintain our 
business-critical processes. We must be 
able to rely on the performance of these 
systems and the underlying data to 
demonstrate the value of our business to our 
shareholders, and to meet our obligations 
under our regulatory agreements, and 
comply with agreements with bond holders 
and other providers of finance. 

We experience a catastrophic/major 
cyber security breach.

Due to the nature of our business we 
recognise that our critical national 
infrastructure (CNI) systems may be a 
potential target for cyber threats. We 
must protect our business assets and 
infrastructure and be prepared for any 
malicious attack. 

Failure to prevent a significant process 
safety event.

Safety is paramount. Some of the assets 
owned and operated by National Grid are 
inherently hazardous and process safety 
incidents, whilst extremely unlikely, 
can occur.

Our objective is to be an industry leader in 
managing the process safety risks from our 
assets to protect our employees, contractors 
and the communities in which we operate. 
We operate in compliance with local 
legislation and regulation. In addition 
we identify and adopt good practices

periodic audits.

Our internal control process
We have a number of processes to support our 
internal control environment. These processes are 
managed by dedicated specialist teams, including 
risk management, ethics and compliance 
management, corporate audit and internal controls, 
and safety, environment and health. Oversight of 
these activities is provided through regular review 
and reporting to the appropriate Board committees 
as outlined in the Corporate Governance section on 
pages 42 to 59. 

Reviewing the effectiveness of our 
internal control and risk management
Each year the Board reviews the effectiveness of 
our internal control systems and risk management 
process covering all material systems, including 
financial, operational and compliance controls, to 
make sure they remain robust. The latest review 
covered the financial year to 31 March 2015 and 
the period to the approval of this Annual Report 
and Accounts. It included:

•   the Certificate of Assurance for noting following 

consideration by the Audit Committee to provide 
overall assurance around the effectiveness of our 
risk management and internal controls systems;

•   where appropriate, assurance from our 

committees, with particular reference to the 
reports received from the Audit, and Safety, 
Environment and Health Committees on reviews 
undertaken at their meetings; and

•   assurances about the certifications required 
under Sarbanes-Oxley as a result of our US 
reporting obligations.

The Board evaluated the effectiveness of 
management’s processes for monitoring and 
reviewing internal control and risk management, 
noting that no significant failings or weaknesses had 
been identified by the review and confirmed that it 
was satisfied the systems and processes were 
functioning effectively.

Our internal control and risk management processes 
comply with the Turnbull guidance on internal 
control and the requirements of the UK Corporate 
Governance Code and the Financial Reporting 

Council’s Guidance on Risk Management, Internal 
Control and Related Financial and Business 
Reporting. 

They are also the basis of our compliance with 
obligations set by the Sarbanes-Oxley Act 2002 and 
other internal assurance activities. The New Code, 
published in September 2014, contained changes 
related to risk management. These changes have 
been reviewed against our risk management 
and internal control systems and processes. 
Refinements will be implemented, as appropriate, 
over the coming year. 

Internal control over financial reporting
We have specific internal mechanisms to govern the 
financial reporting process and the preparation of the 
Annual Report and Accounts. Our financial controls 
guidance sets out the fundamentals of internal 
control over financial reporting, which are applied 
across the Company. 

Our financial processes include a range of system, 
transactional and management oversight controls. 
In addition, our businesses prepare detailed monthly 
management reports that include analysis of their 
results along with comparisons to relevant budgets, 
forecasts and prior year results. These are presented 
to and reviewed by senior management within our 
Finance function. 

These reviews are supplemented by quarterly 
performance reviews, attended by the Chief 
Executive and Finance Director which consider 
historical results and expected future performance 
and involve senior management from both 
operational and financial areas of the business.

Each month the Finance Director presents a 
consolidated financial report to the Board.

As part of our assessment of financial controls in the 
prior year, we identified a number of weaknesses in 
our US financial control framework. We are making 
progress in remediating these weaknesses. For more 
information, including our opinion on internal control 
over financial reporting, see page 173.

The Strategic Report was approved by the Board of Directors on 20 May 2015 and signed on its behalf by:

Dear Shareholders,
Our Board is responsible for shaping the culture, values and 
ethics of National Grid, both within the boardroom and across the 
organisation, by setting the tone from the top and establishing high 
standards of behaviour. 

The changes introduced in 2014 to the UK Corporate Governance 
Code and the Financial Reporting Council guidance on risk 
management have highlighted the need for the Board to consider 
if the current risk management and internal control practices and 
culture of the Company support the spirit of the changes, not just 
the letter. 

The updates to the New Code have been considered by the Board 
and refinements approved so we can report on compliance next year 
as required. It is the intention of the Board that any changes to the 
frequency and level of reporting received by the Board and Audit 
Committee in relation to risk management, compliance and internal 
control as a result of these updates, will also add value to the business. 

A review of our compliance procedures is also underway to make 
sure that we continue to develop and improve our compliance with 
external reporting obligations. In order to further develop our internal 
assurance programme, we formed the Engineering Assurance 
Committee to promote the application of common, consistent, 
engineering assurance methodologies across the Company.

The Board received an in-depth presentation on security and cyber 
security which provided a framework for discussion around the 
threats we face and the effectiveness of our strategy to mitigate the 
inherent risks. We have made a significant investment over the last 
five years to improve our capabilities in this area so we can adapt 
to and address an ever-changing threat landscape. Following this 
session, we agreed that responsibility for making sure we have 
an effective process for managing cyber security risk should be 
delegated to the Audit Committee. You can read more about this 
on page 50. The Board will continue to receive an annual in-depth 
presentation on information systems and security, including 
cyber security.

This year, in addition to Nick Winser and Maria Richter stepping down 
at the 2014 AGM, we have said goodbye to Philip Aiken and Tom King 
and have welcomed John Pettigrew and Dean Seavers as Executive 
Directors in the UK and US respectively. In my role as Chairman and 
leader of the Board I am responsible for ensuring effectiveness in 
all aspects of its role. This includes promoting effective relationships 
and open communication between Directors and encouraging active 
engagement by all members. This is particularly important as the 
membership of the Board changes and new relationships are formed. 
I am pleased to report that the positive outcome of the Board and 
Committee evaluation process reflects this effectiveness. You can 
read more about this on page 46 and the rigorous selection process 
prior to Dean’s appointment on page 58. 

Clear and concise communications with our shareholders remain 
a focus for the Board and we hope that the overview of our business 
model on page 12 helps to articulate how we create value for you, 
our shareholders, as well as our other stakeholders.

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Corporate Governance continued

Governance framework 

Compliance statement
The Board considers that it complied in full with the provisions of 
the UK Corporate Governance Code 2012 (the Code) during the 
financial year being reported, see page 53 for our explanation in 
relation to external audit tendering.

This report explains the main features of the Company’s 
governance structure to give a greater understanding of how the 
main principles of the Code have been applied. The report also 
includes items required by the Disclosure and Transparency Rules. 
The index on page 59 sets out where to find each of the 
disclosures required in the Directors’ Report and in respect of 
Listing Rule 9.8.4, together with the Board’s sign-off on the report. 

UK Corporate Governance Code 2014
The new UK Corporate Governance Code 2014 (the New Code) 
applies to the Company for the next financial year, 2015/16. 
In March, the Board considered the current governance 
arrangements and approved refinements to support compliance 
with the New Code. Details will be provided in the 2015/16 Annual 
Report and Accounts. 

Fair, balanced and understandable
The requirement for Directors to state that they consider the Annual 
Report and Accounts, taken as a whole, is fair, balanced and 
understandable remains a key consideration in the drafting and 
review process. The coordination and review of the Annual Report 
follows a well-established and documented process, which is 
conducted in parallel with the formal audit process undertaken 
by the external auditors and the review by the Board and its 
committees (of relevant sections). 

This process gives the Board comfort that all material statements 
are accurate and that the Annual Report gives sufficient 
prominence to negative as well as positive information. The drafting 
and assurance process supports the Audit Committee and Board’s 
assessment of the overall fairness, balance and clarity of the 
Annual Report and the Directors’ statement on page 78.

Our Board 
Our current Board membership is set out on the previous page, 
with biographical details of Directors on pages 178 to 179. The 
Directors in place during the year are set out on page 49, together 
with details of Board meeting attendance. Committee membership 
during the year and attendance at meetings is set out in each of the 
individual committee reports later in this report. For further details 
about the Directors’ service contracts and letters of appointment, 
see page 67 of the Directors’ Remuneration Report.

Role of our Board
Our Board is collectively responsible for the effective oversight of 
the Company and its businesses. It also determines the strategic 
direction, business plan, objectives and governance structure that 
will help achieve the long-term success of the Company and deliver 
sustainable shareholder value. 

The Board sets the risk appetite for the Company and takes the 
lead in areas such as safeguarding the reputation of the Company 
and financial policy, as well as making sure we maintain a sound 
system of internal control and risk management (see pages 38 to 41). 

The Board’s full responsibilities are set out in the matters reserved 
for the Board, which were updated in January 2015. These are 
available on our website, together with other governance 
documentation.

44

Our Chairman is responsible for the leadership and 
management of the Board and its governance. He ensures the 
Board is effective in its role by promoting a culture of openness 
and debate, facilitating the effective contribution of all Directors 
and helping to maintain constructive relations between 
Executive and Non-executive Directors. 

Our Chief Executive is responsible for the executive leadership 
and day-to-day management of the Company, to ensure the 
delivery of the strategy agreed by the Board. Through his 
leadership of the Executive Committee, he demonstrates 
commitment to safety, operational and financial performance. 

Our Senior Independent Director acts as a sounding board 
for the Chairman and serves as an intermediary for the other 
Directors, as well as shareholders when required.

Independent of management, our Non-executive Directors 
bring diverse skills and experience, vital to constructive 
challenge and debate. Exclusively, they form the Audit, 
Nominations and Remuneration Committees, and have 
an important role in developing proposals on strategy.

Examples of Board focus during the year:
Board strategy session. In addition to time allocated during the 
year at Board meetings, in January the Board took part in a 
half-day interactive strategy session, involving a combination of full 
Board discussions and breakout groups. The Board considered 
questions raised by the business plan and recent strategic analysis, 
future opportunities for the Company including business 
development, mergers and acquisitions and how our core 
capabilities could be exploited. 

The Board found the additional session extremely useful and 
suggested that further regular updates and discussions would help 
consolidate its thinking, in particular in relation to the development 
of a longer-term perspective on potential growth in other 
geographical areas.

European energy policy. The Board received updates on how 
changes in the EU will affect and influence the UK energy policy, 
including Electricity Market Reform, support for interconnectors 
and Carbon Capture and Storage. 

The 2014 UK Winter Outlook. This annual publication confirmed 
that the Company was in a strong position in respect of gas in the 
UK, with no heightened concerns, but for electricity, margins were 
expected to be tight. Updates to the Board confirmed that the 
UK business had a good understanding of the issues and risks. 
A robust mitigation strategy, agreed with the UK Government, 
was approved and implemented.

Interconnector projects. In January, the Board received 
a presentation on Great Britain’s interconnector market and our 
pipeline of opportunities, including an overview of our two most 
advanced projects; potential new links to Belgium and Norway. 
Following feedback provided, the Board approved the final 
investment decision in relation to the Belgium interconnector in 
February 2015 and the interconnector with Norway in March 2015. 

Emerging risks. The Board received a risk update paper including 
an overview of the framework that has been developed to track 
emerging risks and the resulting opportunities and/or threats. 
Additionally, the Board received an update on three themes that 
had emerged from the 2014 risk workshop to make sure that we 
were sufficiently prepared for ‘black swan’ events (catastrophic 
events of extremely high impact and extremely low likelihood). 

Corporate GovernanceUpdates will continue to be provided to the Board on a regular 
basis, as appropriate.

Risk workshop. The Board participated in a risk workshop that 
included an update on the changes introduced by the New Code, 
the annual risk appetite review and an in-depth review of the current 
risk profile of the Company. At the workshop, it was agreed that the 
evaluation of risk appetite should permeate through to the evaluation 
of all new projects and further work was required in relation to the 
risk appetite definitions and the Company’s risk profile. 

Safety updates. Safety is discussed at every Board meeting. 
The Board receives safety updates in the Chief Executive’s report 
and supplementary to this, the Safety, Environment and Health 
(SEH) Committee chairman provides an oral summary of matters 
considered at Committee meetings.

Annual talent management review. The Board noted the progress 
of the development of capacity, capability and the talent pipeline 
and the accelerated development programme, which had resulted 
in long-term career plans being put in place and graduates moving 
through the Company more speedily than in the past.

Examples of expected Board focus for next year: 
•   regular reviews of safety activities;
•   mid-term review of our progress and performance under RIIO;
•   continued detailed review of strategy and financing;
•  key US rate case filings;
•  regulatory compliance;
•  implications of the Integrated Transmission Planning and 

Regulation project on our activities;

•   review of the political situation following the UK general election 

and the impact on energy policy in the UK and EU;

•   refined reporting to strengthen our assessment and monitoring 
of internal control and risk management following the updates 
to the New Code; 

•   reviews into UK and US regulation and the major projects in 

the UK;

•   the 2015 UK Winter Outlook; and
•   results of the 2015 employee opinion survey.

Board composition 
The successful delivery of our strategy depends upon attracting 
and retaining the right talent. This starts with having a high-quality 
Board. Balance is an important requirement for the composition 
of the Board, not only in terms of the number of Executive and 
Non-executive Directors, but also in terms of expertise and 
backgrounds.

While traditional diversity criteria such as gender and ethnicity are 
important, we also value diversity of skills, experience, knowledge 
and thinking styles. You can read about our Board diversity policy 
in the Nominations Committee report on page 58. 

Following the conclusion of the 2014 AGM we said goodbye 
to Maria Richter and Nick Winser from the Board. Additionally, 
Philip Aiken stepped down with effect from 25 February 2015 
and Tom King from 31 March 2015. We welcomed John Pettigrew 
as Executive Director, UK on 1 April 2014 and Dean Seavers as 
Executive Director, US with effect from 1 April 2015. 

Director induction and development
As our internal and external business environment changes, it is 
important to make sure that Directors’ skills and knowledge are 
refreshed and updated regularly. Our Chairman is responsible for 
the ongoing development of all Directors.

To strengthen the Directors’ knowledge and understanding of the 
Company, Board meetings regularly include updates and briefings 
on specific aspects of the Company’s activities. In January the 
Board participated in a strategy session; see the previous page. 

Updates on corporate governance and regulatory matters are 
also provided at Board meetings, with details of development 
and training opportunities for Directors available in our online 
document library.

Additionally, the Non-executive Directors are expected to visit at 
least one operational site annually. In 2014 this included visits in 
the UK to the LNG terminal on the Isle of Grain, the gas distribution 
control centre, and the customer centre and emergency 
dispatch based in Hinckley. And in the US, the Directors met with 
management of the Independent System Operator New England 
and visited the Brooklyn Queens Interconnect project, a Long 
Island power station, and other major projects and stakeholders 
in New York City. Visits to the Long Island power plants and 
the Western Link project are among those planned for 2015. 
These visits provide the opportunity for Directors to meet local 
management teams and discuss aspects of the business 
with employees.

With the agreement of the Board, Executive Directors gain 
experience of other companies’ operations, governance 
frameworks and boardroom dynamics through non-executive 
appointments. The fees for these positions are retained by the 
individual. See page 67 for more details.

The Board in action
Thinking styles session
Following on from the thinking styles session supported by an 
external consultant held in 2014, the Board undertook a second 
session in February 2015. 

The session was specifically designed to encourage diverse 
thinking within the boardroom. New Board members were 
invited to give their thoughts on how the Company operates. 
The session covered the benefits of thinking styles for different 
types of discussion and ways in which the diverse capability 
that exists within the Board could be harnessed to maximise 
its effectiveness. The session also reviewed the progress 
made since the 2014 session.

A thinking styles action has been included in the action plan 
resulting from this year’s Board evaluation; see page 47. 

Directors’ induction programme
Following Dean’s appointment to the Board, the Chairman, Chief 
Executive and Group General Counsel & Company Secretary 
arranged a comprehensive induction programme. The programme 
has been tailored based on his experience and background and 
the requirements of his role. 

Dean’s induction programme has included a meeting with our 
external legal advisors to discuss the duties and requirements 
of being a listed company director in the UK. He has also held 
one-to-one meetings with his fellow Directors and senior 
management, and attended visits to operational sites to build his 
understanding of the Company and its businesses in the UK and 
US. His induction will continue over the coming months and will 
include further operational site visits.

Details of Therese and John’s induction programmes were 
provided in last year’s Annual Report and Accounts. These 
programmes have continued over the year.

Board and committee evaluation 
As shown in the diagram below, we are in the third year of our 
evaluation cycle. This year an internal Board performance 
evaluation was conducted. The evaluation was ‘upward facing’ 
with questionnaires completed by non-Board members on the 
Executive Committee and regular attendees and presenters at 
Board meetings. 

Board and committee evaluation cycle

Year 1 – 2012/13

Externally facilitated evaluation 
–  conducted by independent consultants

Year 2 – 2013/14

Internal review
–  using open questions to the Board from the Chairman

Year 3 – 2014/15

Internal review
–  upward-facing evaluation with questions completed 
by non-Board members on the Executive Committee 
and regular attendees/presenters at the Board and 
its committees

The questions asked covered the following areas: 
•  time and focus for agenda items;
•  the direction/guidance received to support the preparation 

of papers and presentations;

•  coverage by presenters on key topics;
•  values and behaviours displayed by the Board and the 

experience of attending Board meetings;

•  level of challenge and questioning by the Directors; and
•  diversity of thinking styles present on the Board.

The responses were collated into a confidential and non-
attributable report which was presented to the Board in February. 
At this meeting, the Board considered the report and discussed 
its performance generally over the past year. The Board confirmed 
that it had worked well together as a unit, discharged its duties and 
responsibilities effectively over the year; and worked effectively with 
the Board committees.

Following this meeting, a draft action plan was prepared and 
considered by the Board in March. At this meeting, the Board 
agreed a number of actions for the forthcoming year, as set out 
below. Progress against these actions will be monitored throughout 
the year by the Board. 

Environment 
Optimise the boardroom layout to create a more inclusive 
environment for members and presenters. 
Responsibility: Board members/Group General Counsel & 
Company Secretary
Continue to create a more open boardroom atmosphere and culture.
Responsibility: Chairman/Board members

Responsibility: Chairman/Executive Directors/Group General 
Counsel & Company Secretary
Use a diversity of thinking styles.
Responsibility: Chairman/Board members

Board focus 
Continue to manage the strategy agenda. 
Responsibility: Chairman/Chief Executive/Group General 
Counsel & Company Secretary

Progress against last year’s actions has been monitored through 
the year and a commentary against each action is set out opposite.

Committee evaluation
An evaluation of committee performance was also conducted by the 
chairman of each of the Board committees, as well as the Executive 
Committee. The process broadly followed that conducted by the 
Board with questionnaires being completed by regular attendees 
and presenters at the respective committee meetings. The process 
followed by the Nominations Committee was slightly different; 
see ‘The Committee in action’ box on page 57 for more details. 

Following consideration of the results of the evaluation, each 
committee concluded that it had operated effectively throughout 
the year and agreed an action plan to further improve performance. 
Copies of each committee’s action plan were provided to the Board 
and it confirmed that it agreed that each committee had operated 
effectively. 

Progress against the action plans will be monitored through the year 
by the respective committee and the Board.

Non-executive Director independence
The independence of the Non-executive Directors is considered at 
least annually along with their character, judgement, commitment 
and performance on the Board and relevant committees. The Board 
took into consideration the Code and indicators of potential 
non-independence, including length of service. 

At year end, all of the Non-executive Directors, with the 
exception of the Chairman, have been determined by the Board 
to be independent. 

Director performance 
At a private meeting of the Non-executive Directors, Mark Williamson, 
as Senior Independent Director, led a review of Sir Peter’s 
performance. The Non-executive Directors, with input from the 
Executive Directors, assessed his ability to fulfil his role as Chairman 
and the arrangements he has in place, given he is also chairman of a 
FTSE 250 company and the Aircraft Carrier Alliance. They concluded 
that Sir Peter’s performance continued to be effective.

Sir Peter met each Director individually to discuss their contribution, 
performance over the year and training and development needs. 
Following these meetings, Sir Peter confirmed to the Nominations 
Committee that he considered that each Director demonstrated 
commitment to the role and their performance continued to 
be effective. 

Following recommendations from the Nominations Committee the 
Board considers all Directors continue to be effective, committed to 
their roles and have sufficient time available to perform their duties. 
Therefore, in accordance with the Code, all Directors will seek 
election or re-election at the 2015 AGM as set out in the Notice 
of Meeting.

Responsibility: Executive Directors

A number of topics were identified that Directors 
felt needed additional focus by the Board at its 
meetings, for example cyber risk and the UK 
political landscape. Ways to improve the focus on 
each of these topics were discussed at the March 
2014 Board meeting and specific actions were 
agreed and allocated. 
Responsibility: various Board members

Effectiveness 
of the Board

Actions to improve Board effectiveness were 
proposed, for example: continue to improve the 
quality of Board papers; make sure in-depth 
items for Board consideration highlight the 
important issues to be discussed; and encourage 
reporting from management that incorporates 
more input from the Executive Directors. 
Responsibility: Chairman, Chief Executive and 
Group General Counsel & Company Secretary 
as appropriate

Sir Peter Gershon and Steve Holliday have regularly reviewed the 
forward business schedule with the Group General Counsel & 
Company Secretary over the year. The schedule is also included 
with the papers for each Board meeting to ensure Directors are 
aware of forthcoming topics for discussion. Following the 
thinking styles session in February 2015, the schedule was also 
reviewed to consider if any items could be brought forward early 
to allow Directors to contribute to thinking and direction at a 
preliminary stage of the debate. 

The Company Secretariat team engaged with external 
specialists in effective reporting to support the development 
of the information that goes to the Board. The new reporting 
framework has resulted in clearer, more concise papers, which 
has supported improved Board discussion and decision making. 
Following the successful implementation of the new reporting 
framework at Board level it has also been rolled out to the Board 
committees and the Executive Committee.

In February, the Board reviewed progress against the 2013/14 
action plan and noted that all Executive Directors felt 
empowered to input freely at Board meetings and that there 
was open and honest dialogue. The Chairman will continue 
to monitor this on an ongoing basis.

The Board has taken into account the need for additional 
focus in certain areas and this has been reflected in the 
meeting agendas.

Strategy: several papers focusing on strategy and growth have 
been received by the Board over the year in addition to the 
Board strategy session. Topics included: review of the UK gas 
market; US and other market opportunities; exploitation of core 
capabilities; expansion in and outside our core geographies; 
and a general update on the interconnectors. 

Political risk: political updates are provided in the Chief 
Executive’s report to the Board as appropriate. Additional papers 
on the politics of UK and US energy and a general update on 
politics in Europe have been presented to the Board and updates 
will continue to be provided as appropriate.

Cyber risk: an update on cyber risk and security went to the 
Board and Audit Committee in September. At this meeting, 
the Board decided that responsibility for making sure there is 
an effective process for managing cyber security risk should 
be undertaken by the Audit Committee. The Board is scheduled 
to receive an in-depth presentation in November 2015.

Relationship with UK and US regulators: updates on 
the meetings that take place between our Chairman and 
the Chairman of Ofgem are provided to the Board. Updates 
on US regulation and the meetings that take place with the 
US regulators are also provided to the Board in the Chief 
Executive’s report.

The new reporting framework described above will also help 
improve the effectiveness of the Board. As part of the new 
framework, executive owners of papers on the Board agenda 
have a greater input in to and ownership for the preparation of 
papers. Management are encouraged to meet with the executive 
owner at the start of the drafting process to discuss the 
framework for the paper and owners are required to review 
and sign off on the final paper prior to submission to the Board 
or committee.

Investor engagement
We believe it is important to maintain effective channels of 
communication with our debt and equity institutional investors 
and individual shareholders. This helps us to understand their 
views about the Company and allows us to make sure they are 
provided with timely and appropriate information on our strategy, 
performance, objectives, financing and other developments.

Institutional investors 
We carry out a comprehensive engagement programme for 
institutional investors and research analysts. This includes 
meetings, presentations, webinars, attendance at investor 
conferences across the UK and US, and holding road shows in 
major investor centres across Europe, the US and Asia Pacific.

The programme provides the opportunity for our current and 
potential investors to meet with executive and operational 
management.

In the past year, our engagement programme has focused on 
clarifying our Group growth expectations and explaining to 
investors how we expect the Company to continue to perform 
under the RIIO price controls in the UK. These areas of focus have 
been reflected in our regular results presentations as well as in 
more detail during an investor seminar at our Castle Donington site.

In addition to these engagement activities, we also held a 
stewardship meeting in July last year. The event provided major 
investors with an understanding of our performance and an insight 
into the operation of our Board with a particular focus on the work 
of our Remuneration and Audit Committees. The event also 
provided the opportunity for attendees to ask questions and meet 
members of the Board and for our Non-executive Directors to 
further develop their understanding of our shareholders’ views and 
concerns. A copy of the presentation given on the day is available 
in the Investors section of our website.

Sir Peter also contacted our major shareholders in April 2015 to 
offer them the opportunity to meet him or the chairman of the 
Remuneration Committee, Jonathan Dawson, to discuss the Board 
changes that have taken place during the year and the associated 
remuneration arrangements. 

The Board receives regular feedback on investor perceptions and 
opinions about the Company. Specialist advisors and the Director 
of Investor Relations provide updates on market sentiment. 

Each year, the Board receives the results of an independent audit 
of investor perceptions. Interviews with key investors were carried 
out to establish their views on the performance of the business and 
management. The findings and recommendations of the audit were 
discussed in depth by the Board.

Debt investors 
Over the last year representatives from our treasury team, together 
with other senior managers from across the business, have met 
with debt investors in Europe, Canada and the US to discuss 
various topics such as the full-year results.

We also communicate with our debt investors through regular 
announcements and the debt investor section of our website. 
This contains bond prospectuses, credit ratings, materials relating 
to the retail bond issued in 2011 and subsidiary year-end reports. 
The website also contains information about the long-term debt 
maturity profile, so investors can see our future refinancing needs.

Individual shareholders
Engagement with individual shareholders, who represent more 
than 95% of the total number of shareholders on our share register, 
is led by the Group General Counsel & Company Secretary. 
Shareholders are invited to learn more about the Company through 
the exhibits at our AGM and the shareholder networking programme.

The shareholder networking programme includes visits to UK 
operational sites and presentations by senior managers and 
employees over two days. UK resident shareholders can apply 
to take part online via the Investors section of our website.

Annual General Meeting (AGM)
Our AGM will be held on Tuesday 21 July 2015 at The International 
Convention Centre in Birmingham and broadcast via our website. 
The Notice of Meeting for the 2015 AGM, available on our website, 
sets out in full the resolutions for consideration by shareholders, 
together with explanatory notes and further information on the 
Directors standing for election and re-election. 

How our Board operates
The Chairman sets the Board’s agenda in line with its 
responsibilities as set out in the matters reserved for the 
Board. Consideration is also given to the main challenges and 
opportunities facing the Company, making sure adequate time 
is available to discuss all items, including strategic issues.

To support discussion and decision making, Board and committee 
members receive papers sufficiently in advance of meetings so that 
they can prepare for and consider agenda items. Additionally, the 
Chairman holds a short meeting with the Non-executive Directors 
before each Board meeting to discuss the focus of the upcoming 
meeting as well as afterwards to share feedback and discuss the 
dynamics of the meeting. Similarly, the Chief Executive holds 
a short meeting with the Executive Directors and other senior 
management in attendance and shares the feedback from 
these meetings with the Chairman. 

As set out in the table of actions from last year’s Board and 
committee evaluation process, during the year we engaged 
external specialists to review our current papers and develop a new 
reporting framework for the Board and its committees. This has 
resulted in clearer more concise reports, allowing more time for 
discussion and questions.

Committee membership during the year and attendance at 
meetings is set out in each of the individual committee reports 
later in this report. 

Should any Director not be able to attend a Board or committee 
meeting, the Chairman and committee chairman are informed and 
the absent Director is encouraged to communicate opinions and 
comments on the matters to be considered. 

The role and responsibilities of the committees are set out in their 
respective terms of reference, available on our website. The 
committee structure, delegation and reporting lines are set out in 
the diagram below.

In addition to the vertical lines of responsibility and reporting, the 
committees communicate and work together where required. 
For example, on some risk matters the SEH Committee 
collaborates with the Audit Committee. These lines of 
communication are shown in the diagram below. 

Committee agendas and schedules of items to be discussed at 
future meetings are prepared in line with the terms of reference 
of each committee and take account of other topical matters.

At committee meetings, items are discussed and, as appropriate, 
matters are endorsed, approved or recommended to the Board 
by the committee. Following meetings, the chairman of each 
committee provides the Board with a summary of the main 
decisions and discussion points so the non-committee members 
are kept up to date.

Below the Board committees are a number of management 
committees, including the Executive Committee.

The Executive Committee has responsibility for making management 
and operational decisions about the day-to-day running of the 
Company. Further information on some of the management 
committees, including the membership and operation of the 
Executive Committee, is set out on pages 58 and 59.

Audit Committee

Mark Williamson
Non-executive 
Director

Role
Oversees the Company’s financial reporting, and internal controls 
and their effectiveness, together with the procedures for identifying, 
assessing and reporting risks. It also oversees the services 
provided by the external auditors and their remuneration. 

Review of the year
Challenging management on the action they are taking to continue 
to improve the US financial controls environment has remained a 
focus for the Committee over the past 12 months. Although there 
is work still to do, I am pleased to report we are now seeing steady 
progress in this area. 

The US leadership team has been strengthened with the 
appointment of a new US Chief Financial Officer (CFO). The 
Finance Director and the US CFO have continued to keep the 
Committee up to date on progress with regular reports throughout 
the year on further proposed improvements and priorities. 

The past year has also seen two other key appointments –  
a new Head of Corporate Audit (approved by the Committee 
in accordance with its terms of reference) and a new Head of 
Assurance. The Committee has received reports from both 
individuals on their initial observations of their respective functions 
and proposed changes and priorities for the year. 

Following the delegation by the Board for oversight of risk 
management in relation to cyber security, the Committee received 
its first update from internal (corporate) audit on the process for 
identifying, mitigating, monitoring and responding to cyber security 
risks in March.

The Committee has been briefed on the changes to the regulatory 
environment, in particular the audit tender regulations published by 
the Financial Reporting Council, the implications of the Competition 
and Market Authority Order and the final European Commission 
regulations. We discussed and considered the timing of a tender 
for the external audit and agreed that an audit tender process 
should be run later this year. See page 53 for further details. 

Committee membership has also undergone some changes. 
Maria Richter stepped down from the Board at the 2014 AGM. 
In 2015 we have said goodbye to Philip Aiken and welcomed 
Paul Golby and Therese Esperdy to the Committee in February 
and April respectively. I would like to thank Phil for his contribution 
and support to the Committee over the last six years. We are 
looking forward to working with Paul and Therese over what will 
be another busy year.

Significant issues
The most significant issue the Audit Committee considered in 
relation to the financial statements during the year were the US 
financial controls. The Committee also considered the presentation 
of exceptional items, the treatment of the liability management 
programme costs and accounting for agreed legal settlements. 
More detail is provided later in the report. 

Other matters reviewed
Examples of other matters the Audit Committee reviewed:

The new Group consolidation system. Regular progress updates 
on the implementation which is expected to go live later this year. 

Lessons learnt from the March 2014 year-end audit. The 
Committee noted the detailed plans produced by management 
and the external auditors to deliver a more efficient March 2015 
year-end process, including the timing of certain audit testing and 
the approach to subsidiary statutory and regulatory accounts.

Sarbanes-Oxley Act 2002 testing and attestations. The 
Committee received regular updates on the status of testing and 
considered the impact of deficiencies reported at the May 2014 
meeting. During the year, the Company adopted the revised 
framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO). Subsequently, a review of 
all internal controls of financial reporting was undertaken to ensure 
compliance with the updated framework. See page 41 for the 
Company’s statement on the effectiveness of internal control over 
financial reporting.

Accounting for rate regulated activities. The Committee endorsed 
management’s response to the discussion paper issued by the 
International Accounting Standards Board in September 2014 and 
believe that guidance should be introduced that results in the IFRS 
financial statements of the Company more closely reflecting its 
economic performance and position.

Fair, balanced and understandable. The requirement of the Code 
to ensure that the Annual Report and Accounts, taken as a whole, 
is fair, balanced and understandable in the context of the applicable 
accounting standards and confirmed this view to the Board. 

Interim Management Statements (IMS). The Board’s decision to 
cease the publication of an IMS and the impact on the traditional 
role of the Committee. Depending on the content of future market 
updates, the Committee will review these prior to publication. 

Cyber security risk management. A paper from internal 
(corporate) audit on the status of our cyber security risk 
management and external good practice in September 2014. 
In setting the scope of its new responsibilities, the Committee 
considered the level of assurance currently provided by internal 
(corporate) audit and other assurance providers and the frequency 
and extent of information received. Subsequently, the Committee’s 
terms of reference were amended to include this additional 
responsibility in relation to the review of the governance processes 
over cyber security risk and the Committee now receives a regular 
update from the Head of Corporate Audit.

Risk management. Half-yearly updates on the management 
of key risks faced by the Company including changes to the 
corporate risk profile to reflect Executive Committee risk 
management discussions.

Experience
The Board has determined that Mark:
•  has recent and relevant financial experience;
•  is a suitably qualified audit committee financial expert within 

the meaning of the SEC requirements; and

•  is independent within the meaning of the New York Stock 

Exchange listing rules. 

Financial reporting
The Committee monitors the integrity of the Company’s financial 
information and other formal documents relating to its financial 
performance and makes appropriate recommendations to the 
Board before publication.

An important factor in the integrity of financial statements is making 
sure that suitable and compliant accounting policies are adopted 
and applied consistently on a year-on-year basis and across the 
Company. In this respect, the Committee also considers the 
estimates and judgements made by management when 
accounting for non-standard transactions, including the treatment 
of exceptional items. Two examples of these are set out below. 

These considerations are supported by input from other assurance 
providers such as the group controls, risk management and ethics 
and compliance teams, the business separation compliance 
officer, internal (corporate) audit and the SEH Committee, as well 
as our external auditors. In addition, the Committee also considers 
reports of the Disclosure Committee. See page 59 for more 
information on the role of the Disclosure Committee.

The Committee reviews and approves the external audit plan 
annually (see page 53) and, as part of this, considers the significant 
risks upon which the external auditors will focus their audit. The 
independent auditors’ report (pages 79 to 84) highlights areas of 
focus, including some of the issues that the Committee discussed 
during the year.

Other risks, including the accuracy and valuation of treasury 
derivative transactions, accounting for pension obligations, 
accuracy of capital expenditure, revenue recognition and valuation 
of environmental provisions were not considered in detail by the 
Committee during the year as nothing significant arose that 
warranted Committee attention. 

Summarised below are the issues which attracted the most focus, 
and time, of the Committee in relation to the financial statements 
during the year. 

US financial controls. The Committee has continued to devote a 
significant amount of time challenging management on the action 
they are taking to continue to improve the US finance control 
environment. There has been continued focus on embedding the 
enterprise resource planning system in the US and the benefits this 
system now brings. The Committee has received regular updates 
from management on progress against the measures taken to 
remediate US financial control deficiencies. 

In October, a new US CFO was appointed to lead the US finance 
team. She initiated a granular review of the US finance function to 
understand the current service levels and key learnings from prior 
initiatives, including the successes as well as initiatives that did not 
fully achieve their goals. 

The outputs from this review were incorporated into a new US 
finance function initiative which is intended to address the root 
cause of issues identified by the review and simplify and 
standardise processes. 

In January 2015, the Committee received a presentation on the 
initiative to understand the approach being taken, the stages 
involved and the underlying issues that the initiative was aiming 
to resolve. Management sought input and feedback from the 
Committee on the direction, focus and timing of the proposed 
initiative. The Committee discussed the proposal and asked 
questions about the initiative before approving the approach. 
Regular updates will be provided to the Committee through 
the year so that progress can be monitored. 

During the year, the Committee challenged management in 
the US on its regulatory filing obligations, noting that due to the 
system implementation issues, not all filings were made on time. 
Management presented and, during the course of the year, 
delivered on a detailed plan to complete the filings and remediate 
the process. All regulatory filings are now up to date and 
management communicated with the regulators throughout 
the process.

Presentation of exceptional items. At the half year and year end, 
the Committee examined an analysis of items to be classified as 
exceptional to make sure the items did not include income or costs 
relating to the underlying business performance. 

In particular, the Committee considered the treatment of the liability 
management programme costs at the year end. Management 
proposed that the costs associated with the debt redemptions 
should be treated as exceptional as they were one-off, significant 
and outside the ordinary course of business. To include this cost 
in underlying finance costs would otherwise distort users’ 
understanding of the business performance. This proposal was 
in line with the exceptional items accounting policy in the Annual 
Report and Accounts and the historical treatment of debt 
redemption costs.

The Committee agreed that the classification of this item was 
appropriate. See note 4 footnote 8 on page 104. 

51

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15External audit
The Committee is responsible for overseeing relations with the 
external auditors, including the approval of fees, and makes 
recommendations to the Board on their appointment and 
reappointment. Details of total remuneration to auditors for the year, 
including audit services, audit-related services and other non-audit 
services, can be found in note 3(e) of the consolidated financial 
statements on page 102.

Auditor independence and objectivity
The independence of the external auditors is essential to the 
provision of an objective opinion on the true and fair view presented 
in the financial statements. 

Auditor independence and objectivity is safeguarded by a number 
of control measures, including:

•  limiting the nature and value of non-audit services performed 

by the external auditors;

•  ensuring that employees of the external auditors who have 

worked on the audit in the past two years are not appointed to 
senior financial positions within the Company in line with our 
internal code; 

•  monitoring the changes in legislation related to auditor objectivity 

and independence to help ensure we remain compliant;

•  providing a business conduct helpline that employees can use to 
report any concerns, including those relating to the relationships 
between Company personnel and the external auditor;
•  the rotation of the lead engagement partner at least every 

five years; 

•  PwC’s internal independence rules and processes which have 
been designed to exceed professional standards and focus on 
both personal independence and scope of services; 

•  independent reporting lines from PwC to the Committee and the 

opportunity to meet with the Committee independently; and
•  an annual review by the Committee of the structures, policies 
and practices in place to make sure the external auditors’ 
objectivity and independence is maintained.

A new lead engagement partner will be appointed for the 2015/16 
financial year following the completion of the current lead audit 
partner’s tenure.

Corporate Governance continued

Accounting for agreed legal settlements. During the year, the 
Company reached negotiated settlement agreements in a legal 
case. The Company was awarded a total of £113 million (including 
allowance for legal costs incurred). Due to the size of the impact on 
the income statement, the Committee agreed with management’s 
decision that this was not considered to be exceptional for the year. 
The Committee reviewed and challenged the classification of the 
settlements and agreed that £56 million be recognised in the 
income statement in the year, with the remainder credited to 
property, plant and equipment. Management is waiting for 
confirmation from Ofgem of the regulatory treatment of these 
awards under RIIO.

Confidential reporting procedures and whistleblowing 
The integrity of the financial statements is further supported by the 
confidential reporting and whistleblowing procedures we have in 
place. The Committee reviews these procedures once a year to 
make sure that complaints are treated confidentially and that a 
proportionate, independent investigation is carried out in all cases. 

Internal (corporate) audit 
The corporate audit function provides independent, objective 
assurance to the Audit, SEH and Executive Committees on 
whether our existing control and governance frameworks are 
operating effectively in order to meet our strategic objectives. 
Assurance work is conducted and managed in accordance with 
the Institute of Internal Auditor’s International Standards for the 
Professional Practice of Internal Auditing and Code of Ethics. 

To keep the Committee informed of trends identified from the 
assurance work and to update on the progress against the 
corporate audit plan, the Head of Corporate Audit reports to 
the Committee at least twice each year. These reports present 
information on specific audits, as appropriate, summarise common 
control themes arising from the work of the team and update on 
progress with implementing management actions. Where control 
issues are identified, senior leaders may be invited to attend 
Committee meetings to provide a commentary around the actions 
they are taking to improve the control environment within their area 
of responsibility.

In order to meet the responsibility and objectives set out in the 
Corporate Audit Charter, audits of varying types and scopes are 
performed as part of the annual corporate audit plan. The audit 
plan is based on a combination of risk-based and cyclical reviews, 
together with a small amount of work that is mandated, typically 
by US regulators. 

Inputs to the audit plan include risk registers, corporate priorities, 
external research of emerging risks and trends and discussions 
with senior management to ensure that the plan aligns with the 
Committee and Company’s view of risk. The audit plan is 
considered and approved by the Committee annually.

52

Corporate GovernanceNon-audit services provided by the external auditors
In accordance with our policy, non-audit services provided 
by the external auditors above a threshold of £50,000 require 
approval in advance by the Committee. 

Below this threshold, all requests are approved in advance by 
the Finance Director and do not require Committee pre-approval. 
This reduces the administrative burden on the Committee. A full 
list of all Committee and Finance Director approved non-audit 
work requests is presented to the Committee annually to ensure 
the Committee is aware of all non-audit services provided.

Additionally, the Committee receives quarterly reports from 
management on non-audit services and other consultants’ 
fees to monitor the types of services being provided and 
fees incurred. 

Approval for the provision of non-audit services is given on the 
basis the service will not compromise independence and is a 
natural extension of the audit or if there are overriding business 
or efficiency reasons making the external auditors most suited to 
provide the service. Certain services are prohibited from being 
performed by the external auditors, as required under the 
Sarbanes-Oxley Act 2002.

Total non-audit services provided by PwC during the year ended 
31 March 2015 were £0.9 million (2014: £1.7 million), which 
comprised 7% (2014: 13%) of total audit and audit-related fees 
(see note 3(e)). 

Total audit and audit-related fees include the statutory fee and 
fees paid to PwC for other services that the external auditors 
are required to perform, for example regulatory audits and 
Sarbanes-Oxley Act attestation. Non-audit fees represent all 
other services provided by PwC not included in the above.

Non-audit services provided by PwC in the year included tax 
compliance services in territories other than the US (£0.4 million), 
the significant majority of which relates to the UK.

The Committee considered that tax compliance services were 
most efficiently provided by the external auditors, as much of 
the information used in preparing computations and returns is 
derived from audited financial information. In order to maintain 
the external auditors’ independence and objectivity, 
management reviewed and considered PwC’s findings and 
PwC did not make any decisions on behalf of management.

Audit quality
To maintain audit quality and provide comfort on the integrity of 
financial reporting, the Committee reviews and challenges the 
proposed external audit plan including the scope and materiality 
to make sure that PwC have identified all key risks and developed 
robust audit procedures and communication plans. 

The Committee also considers PwC’s response to accounting, 
financial control and audit issues as they arise, and meets with 
them at least annually without management present, providing 
the external auditors with the opportunity to raise any matters 
in confidence. 

Auditor appointment 
An annual review is conducted by the Committee of the level 
and constitution of the external audit and non-audit fees 
and the effectiveness, independence and objectivity of the 
external auditors.

The annual review includes consideration of:

•  audit quality and the external audit process globally;
•  the auditors’ performance and delivery against the audit plan;
•  the expertise of the firm and our relationship with them including 

the level of challenge; and

•  the results of online questionnaires completed by the Chairman, 

Committee members, Executive Directors and senior 
representatives from the finance team. The questions focused 
on: the quality of service; sufficiency of resources; planning and 
execution of the audit; communication and interaction; and 
overall satisfaction. No material issues were identified. 

Following this year’s annual review, the Committee was satisfied 
with the effectiveness, independence and objectivity of the external 
auditors, and recommended to the Board their reappointment for 
a further year. A resolution to reappoint PwC and giving authority 
to the Directors to determine their remuneration will be submitted 
to shareholders at the 2015 AGM.

Audit tender
PwC have been the Company’s external auditors since the merger 
with Lattice Group plc in 2002, having been the incumbent external 
auditors of both the merging parties and the audit contract has not 
been put out to tender since then. Their performance has been 
reviewed annually by the Committee since that time.

The Committee discussed the implications of the Competition 
and Market Authority Order requiring FTSE 350 companies to 
hold an audit tender every 10 years as well as the final European 
Commission (EC) regulations, which came into EU legislation in 
June 2014. The Committee noted that based on the EC transitional 
arrangements, the final year in which PwC can be appointed as the 
Group’s auditors is for the year ended 31 March 2020.

At its meeting in May 2015, the Committee considered the timing of 
a potential tender for the external audit. The Committee considered 
the continued US financial controls improvement programme and 
the services we currently receive from other external audit firms 
that may be considered in a tender process. It concluded that, 
firstly, in order to ensure an orderly transition and secondly, to 
ensure compliance with the EC regulations on the provision of 
prohibited services, an audit tender process will be run later this 
year for the audit of the year ending 31 March 2018. PwC will not 
be invited to tender. 

No representatives from PwC were present during the Committee’s 
discussion of the options for a tender of the external audit. 

There are no contractual obligations restricting our choice 
of external auditors and we have not entered into any auditor 
liability agreement.

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Corporate Governance continued

Risk management and internal control
The Audit Committee monitors the effectiveness of the risk 
management and internal control processes during the year 
through the biannual reports it receives and reports to the Board 
on the outcome. The review covers all material controls, including 
financial, operational and compliance controls. Please see page 41 
for further details about the review of effectiveness. 

In support of our compliance with the New Code, reporting to the 
Audit Committee on risk management and internal control has 
been reviewed by the Board and refinements will be adopted for 
the financial year 2015/16.

Details of our internal control systems, including those relating to 
the financial reporting process, can be found on pages 38 to 41 
and page 173. 

Risk management
The Executive Committee discusses the principal risks faced by the 
Company and updates the corporate risk profile every six months. 
The approved profile is subsequently shared with the Audit 
Committee, along with US and UK regional risk profiles, as part 
of our continuous risk management process. 

To continuously improve and remain at best practice levels, the 
risk management team reviews risk process standards, emerging 
trends and concepts being driven by the main consultancy firms 
and seeks to apply these as appropriate. The standards issued by 
the COSO and the international risk standard ISO 31000 continue 
to inform the principles of our risk management process. 

During the year, we adopted the revised framework issued by 
the COSO for our internal controls over financial reporting. This 
introduced specific principles to cover fraud risk assessment and 
information technology. We also reviewed the procedures for the 
identification, assessment, mitigation and reporting of risks.

Further details of our risk management systems can be found 
on pages 38 to 41 and our risk factors are described in full on 
pages 173 to 176.

Compliance management
Compliance management has been integrated into a new Global 
Assurance team which incorporates ethics, risk management, 
licence management and records management with a view to 
improving visibility and reporting in all areas. 

Biannual reports to the Committee focus on compliance with 
external legal obligations and regulatory commitments. During the 
year, the Committee requested that additional detail be added to 
the reports against each of the actual or potential non-compliance 
items identified to show the person responsible and provide a 
summary of the actions being taken to resolve the actual or 
potential non-compliance. 

The Committee also received annual reports on the Company’s 
anti-bribery procedures and whistleblowing procedures and 
reviewed their adequacy. It noted that no material instances of 
non-compliance had been identified.

Going concern
Our going concern process is an extension of our business 
planning process, and is further supplemented by our annual 
budget and other liquidity risk management controls. Our five 
year business plan and one year budget were reviewed and 
approved by the Board at its meetings in November 2014 and 
March 2015 respectively. The Finance Committee provides 
ongoing oversight of our liquidity policy, which requires us 
to maintain sufficient liquidity for a rolling 12 month period.

Given our business model, current regulatory clarity and 
other factors impacting our operating environment, and the 
robustness of our business planning process and scenario 
analysis, we have concluded the going concern assessment 
period is the five years ending 31 March 2019, in line with our 
business plan. We will reassess this period annually in light of 
developments in our operating environment, business model 
and strategic priorities. 

Our business plan considers the significant solvency and 
liquidity risks involved in delivering our business model in light 
of our strategic priorities. The business plan models a number 
of upside and downside scenarios, derived from the risks and 
opportunities identified, and determines the impact these would 
have on our results and financial position over the five year 
period. In addition, we have reviewed and challenged a number 
of worst case scenarios and their possible remediation.

Our business model calls for significant capital investment to 
maintain and expand our network infrastructure. To deliver this, 
our business plan highlights that we will need to access capital 
markets to raise additional funds from time to time. We have a 
long and successful history in this regard. Our business plan 
also models various KPIs used by lenders and credit rating 
agencies in assessing a company’s credit worthiness. These 
models indicate that we should continue to have access to 
capital markets at commercially acceptable interest rates 
throughout the five year period. To monitor and control risks 
around access to capital markets, we have policies and 
procedures in place to help mitigate, as far as possible, any 
risk of a change in our credit ratings and other credit metrics.

Having made enquiries and reviewed management’s 
assessment of the going concern assumption, the Directors 
have a reasonable expectation that the Group has adequate 
resources to continue in operational existence for the period of 
the going concern assessment. For this reason, the Directors 
are satisfied that, at the time of approving the financial 
statements, it is appropriate to continue to adopt the going 
concern basis in preparing the consolidated and individual 
financial statements of the Company.

More detail on our financial risks, including liquidity and solvency, 
is provided in note 30 to the consolidated financial statements. 
There have been no major changes to the Group’s significant 
liquidity and solvency risks in the year.

Corporate GovernanceFinance Committee

Therese Esperdy
Committee chairman

Role
Sets policy and grants authority for financing decisions, credit 
exposure, hedging and foreign exchange transactions, guarantees 
and indemnities subject to the risk appetite approved by the Board. 
It also approves other treasury, tax, pension funding and insurance 
strategies and, if appropriate, recommends these to the Board.

Review of the year
My first eight months as chairman have been busy but enjoyable. 
In July, we said goodbye to Maria Richter who stepped down 
from the Board. I would like to thank her for her contribution to 
the Committee and for her guidance and support during the 
handover period. 

As part of my induction to the Board and before taking over 
as chairman of the Committee, I met employees involved in the 
work of the Committee from finance, treasury, tax, pensions and 
insurance in the UK and US. I also had several opportunities to 
meet the wider UK and US tax, insurance and treasury teams 
which has furthered my understanding of our treasury operations. 

This year, we continued to focus on funding plans to take into 
account international debt market conditions. The Committee 
reviewed and agreed a liability management programme 
which resulted in the repurchase of £0.9 billion of bonds.

The Committee also received regular updates on negotiations 
in relation to the European Investment Bank (EIB) loan before 
agreeing the £1.5 billion loan agreement with the EIB in 
November 2014. 

Matters considered
Examples of matters the Committee considered during the 
year include: 

•  funding requirements and financing for the business plan;
•  setting and reviewing treasury policies;
•  treasury performance updates provided at each meeting;
•  UK and US tax updates;
•  US energy procurement activities;
•  annual update on the electricity and gas trading activities 

in the UK;

•  credit rating agencies’ view on the Company;
•  foreign exchange policy;
•  interest rate risk management;
•  the draft going concern statement for the half and full-year 

results prior to consideration by the Audit Committee and Board;
•  pensions updates, including funding of the Company’s pension 

deficits; and

•  insurance renewal strategy.

The Committee in action 
Evaluation of Committee performance
The Committee performance evaluation process this year 
was an upward facing process undertaken by non-Committee 
members and regular attendees/presenters. This was in line 
with the process adopted by the other committees (except the 
Nominations Committee). 

We also considered the financial headroom policy. During the 
financial crisis, the Committee approved a policy to hold 12 months 
of liquidity and a minimum sum as cash or liquid assets. The 
Committee noted that the Group’s liquidity was monitored on 
a regular basis both internally and externally and took into 
consideration the sources of liquidity. In light of the improved 
access to liquidity the Committee approved a simplification of 
the policy.

The Committee concluded that it had operated effectively 
throughout the year and agreed an action plan for 2015/16 
to further improve performance. 

An update on the evaluation including the draft Committee 
action plan was reported to the Board in May 2015. Progress 
against the action plan will be monitored through the year by 
the Committee and the Board.

External advisors have presented to the Committee throughout the 
year, including a credit rating agency on their methodology and an 
update from insurance brokers on the global property insurance 
market, including the current trading environment, market selection, 
new risks, client trends and the future outlook for insurance. 

For the year ahead, we will focus on our funding needs, liquidity 
management, alternative sources of funding and pensions 
investment strategy.

Safety, Environment and Health Committee

Paul Golby
Committee chairman

Role
The Committee reviews the strategies, policies, initiatives, risk 
exposure, targets and performance of the Company and, where 
appropriate, of its suppliers and contractors in relation to safety, 
environment and health. It monitors the resources we use for 
compliance and driving improvement in these areas and reviews 
investigations into major incidents.

Review of the year
Following Philip Aiken’s departure from the Board at the end of 
February, I have taken over as chairman of the Committee. I have 
been a member of the Committee for the last three years and over 
this time we have seen the Company make significant progress in 
process safety management and the safety performance of both 
the UK and US businesses, with the US closing the gap on the UK 
in terms of employee and contractor LTIs. I hope to see further 
progress in these areas going forwards. 

We welcomed Andrew Bonfield to the Committee at the beginning 
of the year. Andrew is a member of the Chief Financial Officers 
Leader Group of the Accounting for Sustainability (A4S) project, 
which challenges organisations to demonstrate the commercial 
rationale for incorporating sustainability into decision making and 
to manage the related risks and opportunities. He also chairs the 
Company’s Engineering Assurance Committee, which now reports 
on a six monthly basis to the Committee. 

We have continued to focus on process safety and establishing 
a safety management system across both our UK and US 
businesses. We have spent time looking at the risks relating to our 
US LNG assets and the measures being introduced to address 
these (see ‘The Committee in action’ below). 

Following a fatality involving a contractor at our Rhode Island gas 
distribution business, we spent time with senior local management 
considering the causes of the incident and how best to ensure that 
safety procedures are understood and complied with at all times, 
by both employees and contractors. 

In terms of environmental matters, we have continued to monitor 
our strategy and approach to sustainability. In particular, we have 
looked at how we are working with governments and bodies such 
as the US Environmental Protection Agency to influence regulations 
that directly impact on our business. 

We also considered the Health and Wellbeing strategy and the 
work being done on data management, improved line management 
training and providing support and guidance to employees to 
address levels of absenteeism. 

56

Matters considered
Examples of matters the SEH Committee reviewed during the 
year include:

•   ongoing monitoring of safety performance and significant 

incidents in both the US and the UK;

•   lessons learnt and steps taken following a fatality of a member 
of the public in the UK in April 2014 and a contractor fatality 
in the US in November 2014;

•   in-depth reviews of incidents in both the UK and US gas 
businesses where failure to follow due process led to 
high pressure releases placing the employees involved 
in potential danger;

•  compliance with US gas pipeline safety regulations in the light 

of new regulations and evolving enforcement policies by 
our regulators;

•   review of the role and set up of the Engineering Assurance 
Committee which was formed last year to promote the 
application of common, consistent, engineering assurance 
methodologies across the Company;

•   conclusion of a review of the interfaces between our IT systems 

and safety processes; 

•   the use of bars in the UK gas distribution business for the break 
up and removal of gas mains below 6" in diameter, looking at 
safety issues and available alternatives; and

•   climate change strategy, including performance against 

emissions targets and carbon budgets.

The Committee in action 
US LNG assets
As part of its focus on process safety and the management 
of major hazard assets, the Committee has spent time with the 
US business looking at the risks surrounding its LNG assets, 
as a number of these assets are located close to areas that 
have pockets of relatively dense population. 

The Committee considered the possible risk reduction 
measures for two key sites, Commercial Point in Massachusetts 
and Providence in Rhode Island, where the risk levels had been 
established to be highest. Philip Aiken visited both sites and 
members of the Committee received additional training on 
LNG process safety risks and the relevant risk assessment 
methodologies. 

Over the following 12 months the Committee, through regular 
reports, oversaw the implementation of the measures proposed, 
including the installation of automatic shutdown mechanisms 
which was completed at these plants in June 2014. The 
Committee also reviewed the proposed timetable for dike 
redesign and construction to improve containment of LNG 
escapes in the event of an incident and recommended 
completion be brought forward by several months.

Corporate GovernanceNominations Committee

Sir Peter Gershon
Committee chairman

Role
Responsible for considering the structure, size and composition 
of the Board and committees, and succession planning. It also 
identifies and proposes individuals to be Directors and executive 
management reporting directly to the Chief Executive, and 
establishes the criteria for any new position.

Review of the year
Succession planning continues to be an important responsibility of 
this Committee, and is reflected in the time spent on the topic this 
year. The process of building a strong and effective Board requires 
a good balance of continuity and refreshment. 

As described in my foreword to the Corporate Governance report, 
during the year we have undertaken a rigorous recruitment process 
to select Dean Seavers as a successor to Tom King, a key 
appointment to the Board. Details of our process are included later 
in this report on page 58. 

Balance is an important consideration in recruitment, not only in 
terms of the number of Executive and Non-executive Directors, but 
also in terms of the range of expertise and backgrounds. In setting 
the specification of the role, we reviewed the existing skills, 
experience and diversity of the Board, including diversity of thinking 
styles, and identified areas that were essential or highly desirable in 
potential candidates. 

The fit with current membership and how the individuals combine 
to add value was also taken in to account in the decision making 
process. Dean brings valuable skills and experience that 
complement the existing Board members and provides a fresh 
perspective and challenge to Board discussions. 

Last year we set out eight measurable objectives to support our 
Board diversity policy. We have conducted our annual review of 
the policy and I am pleased to report that we are on track against 
the objectives we set. 

We currently have 27.3% women on our Board and 24.1% in our 
senior management population. We have included examples of 
how the Company supports women throughout our businesses 
on page 25. 

Following the changes in Board membership, the composition 
of the committees was also reviewed. Paul Golby has become 
chairman of the SEH Committee and joined the Audit Committee 
as a member in place of Philip Aiken to maintain continuity between 
the two committees. 

The Committee also considers succession planning over the 
long-term, for both Executive and Non-executive positions, to 
ensure that we have the right mix of skills and experience as the 
Company evolves and so that change can be effectively managed. 

Matters considered
Examples of matters the Nominations Committee considered 
during the year include: 

•  Director appointments and leavers, see page 58 for details of the 

Executive Director appointment process;

•  Board and committee membership following changes to the 

composition of the Board;

•  the executive succession planning focusing on the identification, 

development and readiness of successors to the Executive 
Committee in particular;

•  review of Sir Peter’s performance as Chairman, led by Mark 

Williamson, the SID; 

•  the proposed structure for the UK business;
•  feedback on the key issues to be covered by the talent update 
paper to the Board to provide focus for the discussion; and
•  the Committee’s performance; see ‘The Committee in action’ 

below.

The Committee in action 
Evaluation of Committee performance
The Nominations Committee performance evaluation process 
took a slightly different approach to the evaluations for the 
Board and other committees. Committee members were 
asked to provide feedback on how effectively it had dealt with 
the main topics considered in the last year and its duties and 
responsibilities; how it had worked together as a unit; and the 
strengths and weaknesses of the Committee and how these 
could be addressed by the action plan. 

Following consideration of the Committee’s performance over 
the year and the above questions, the Committee concluded 
that it had operated effectively throughout the year and agreed 
an action plan for 2015/16, which included refinements to the 
appointment process of future non-executive and executive 
directors to make sure that we continuously improve our robust 
approach, including briefings for Non-executive Directors on 
their role in the selection and appointment of executive directors. 

Additionally, the time spent discussing senior executive 
succession planning will be reviewed to make sure that 
Committee input continues to be provided, as appropriate, 
to support senior appointments. 

An update on the evaluation including the draft Committee 
action plan was reported to the Board in May 2015.

Appointment process
Executive Director
The recruitment process undertaken for the appointment of Dean 
Seavers was formal, rigorous and transparent. The Nominations 
Committee appointed Korn Ferry as the search consultancy, and 
the following process was undertaken:

•  with input from the Committee members, a role and person 

specification was prepared;

•  Korn Ferry conducted initial searches, meeting eight potential 

candidates and shortlisted three candidates;

•  a series of interviews of the shortlisted candidates were 

conducted by Sir Peter Gershon, Steve Holliday, Andrew Bonfield, 
Mark Williamson, Nora Mead Brownell and Mike Westcott 
(the Group Human Resources Director);

•  following a review of the combined ratings from all the 

interviewers, the Nominations Committee selected two 
candidates for further consideration;

•  final interviews with the two candidates were carried out by 

Steve Holliday, Nick Winser, John Pettigrew, Nora Mead Brownell 
and members of the Executive Committee;

•  following discussion, the Nominations Committee recommended 
Dean Seavers as its preferred candidate for appointment to the 
Board, noting that all members had met Dean; and

•  the Board approved the appointment as recommended. 

In addition to providing external search consultancy services to 
the Company, Korn Ferry also provided IT consultancy, e-learning 
services and coaching for senior management.

John Pettigrew was appointed to the Board with effect from 
1 April 2014. A description of the process undertaken in relation 
to his appointment was provided in the 2013/14 Annual Report 
and Accounts. 

Board diversity and the Davies Review 
At National Grid, we believe that creating an inclusive and diverse 
culture supports the attraction and retention of talented people, 
improves effectiveness, delivers superior performance and 
enhances the success of the Company.

Our Board diversity policy promotes this and reaffirms our 
aspiration to meet and exceed the target of 25% of Board positions 
being held by women by 2015, as set out by Lord Davies. 

We currently have 27% women on our Board and 22% women 
on our Executive Committee. The number of women in senior 
management positions and throughout the organisation is set out 
on page 25 along with examples of the initiatives to promote and 
support inclusion and diversity throughout our Company. 

During the year, the Committee reviewed the Board diversity policy 
and progress made against the objectives which were approved 
to support the implementation of the policy as set out below: 

The Board aspires to exceed the target of 25% of Board positions 
to be held by women by 2015.
Objective met – we currently have 27% women on our Board. 
All Board appointments will be made on merit, in the context of the 
skills and experience that are needed for the Board to be effective.
Objective met – John Pettigrew and Dean Seavers were 
appointed on merit. 
We will only engage executive search firms who have signed up to 
the Voluntary Code of Conduct on gender diversity.
Objective met – Korn Ferry are signed up to the code. 

Where appropriate, we will assist with the development and 
support of initiatives that promote gender and other forms of 
diversity among our Board, executive and other senior management.
Objective met – see page 25 for further details. 
Where appropriate, we will continue to adopt best practice 
in response to the Davies Review.
Ongoing – as appropriate. 
We will review our progress against the Board diversity 
policy annually.
Objective met – ongoing.
We will report on our progress against the policy and our objectives 
in the Annual Report and Accounts along with details of initiatives 
to promote gender and other forms of diversity among our Board, 
Executive Committee and other senior management.
Objective met – ongoing.
We will continue to make key diversity data, both about the Board 
and our wider employee population, available in the Annual Report 
and Accounts.
Objective met – ongoing.

Progress against the objectives and the policy will continue to be 
reviewed annually and reported in the Annual Report and Accounts. 

Executive Committee
Led by the Chief Executive, the Executive Committee oversees the 
safety, operational and financial performance of the Company. It is 
responsible for making day-to-day management and operational 
decisions it considers necessary to safeguard the interests of the 
Company and to further the strategy, business objectives and 
targets established by the Board. 

It approves expenditure and other financial commitments within its 
authority levels and discusses, formulates and approves proposals 
to be considered by the Board. 

The Committee in action 
During the year, the Executive Committee reviewed and 
discussed a proposed joint venture with the Berkeley Group. 
The strategic aim was to unlock value in our surplus London 
property portfolio and transform redundant land to help meet 
the current housing and commercial needs of London. 

The proposal was initially presented to the Committee for 
consideration. Feedback was provided, with requests for 
further information and clarification on aspects of the proposal. 
Committee members then worked closely with management 
and specialist teams to develop the proposal. 

The proposal returned to the Committee for review and was 
approved for recommendation to the Board. Following 
presentation and review at its November meeting, the Board 
gave final approval of the arrangement. The joint venture, called 
St William Homes, was formally announced in November.

The nine Committee members have a broad range of skills and 
expertise, which are updated through training and development. 
Some members also hold external non-executive directorships, 
giving them valuable board experience.

The Committee officially met 12 times this year, but the members 
interact much more regularly. Those members of the Committee 
who are not Directors regularly attend Board and committee 
meetings for specific agenda items. This means that knowledge is 
shared and every member is kept up to date with business activities 
and developments.

Management committees
To help make sure we allocate time and expertise in the right way, 
the Company has a number of management committees, which 
include the Disclosure Committee, Global Ethics and Compliance 
Committees and the Global Retirement Plan Committee. These 
management committees provide reports, where relevant, to the 
appointing committee in line with our governance framework on 
the responsibilities they have been delegated.

Disclosure Committee
The role of the Disclosure Committee is to assist the Chief Executive 
and the Finance Director in fulfilling their responsibility for overseeing 
the accuracy and timeliness of the disclosures made – whether in 
connection with our presentations to analysts, financial reporting 
obligations or other material stock exchange announcements, 
including the disclosure of price sensitive information.

This year the Committee met to consider the announcements of 
the full and half year results and the July 2014 Interim Management 
Statement (IMS) and reported on the matters arising to the Audit 
Committee. In doing so it spent time considering the Company’s 
disclosure obligations relating to identified weaknesses in internal 
controls over financial reporting in the US, and whether these 
should be considered material for the Company as a whole, and the 
process for the publication of unaudited year-end financial results. 

The Committee also considered the Company’s disclosure 
obligations relating to delays in cable manufacturing and the 
consequential impact on capital expenditure for the West Coast 
HVDC Link as well as the accounting treatment and disclosure 
for agreed legal settlements. 

Following the removal of the requirement to publish an IMS, the 
Committee will review the investor newsletters prior to publication 
to the extent they contain updated technical guidance on the 
Company’s performance or other price-sensitive information. 

The Committee also reports the results of its evaluation of 
the effectiveness of the Company’s disclosure controls to the 
Audit Committee.

The Committee is chaired by the Finance Director and its 
members are the Group General Counsel & Company Secretary, 
the Global Tax and Treasury Director, the Group Financial 
Controller, the Director of Investor Relations, the Head of Corporate 
Audit and the Deputy Group General Counsel, with other attendees 
as appropriate.

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Directors’ Remuneration Report

The Remuneration Committee believes that the policy endorsed 
last year by shareholders is fully aligned with the Company’s 
strategy and with the experience of shareholders in general. 
It also believes that, based on our appraisal of performance 
against our demanding targets to date, the policy is not inflationary 
compared with previous arrangements. We will, however, continue 
to reassess remuneration policy and targets for future awards so 
that we can remain confident they are still meeting the objectives 
set by the Committee. 

Performance for the year
APP
National Grid has achieved another year of strong financial 
performance in the UK and solid performance in the US with 
record investment levels. The financial measures for the APP were 
adjusted EPS and either Group RoE, UK or US RoE depending 
on role. At 60.6 pence, the adjusted EPS figure for APP was up 
6.3 pence (12%) on 2013/14. The EPS figure used for the APP 
calculation differs slightly to the reported EPS figure of 58.1 pence 
as it is adjusted for the impact of timing and actuarial assumptions 
on pensions and other post-employment benefits (OPEB). Group 
RoE was 11.8%, ahead of last year’s 11.4% result. Our UK RoE was 
14.3%, including the benefit of a legal settlement referred to in the 
report of the Audit Committee on page 52. In the US, our RoE was 
8.4%, which was slightly down on last year. As a result, in respect 
of financial metrics for the APP (representing 70% of the value of 
the award), we have made awards of between 50% and 100% of 
the maximum potential to the Executive Directors. The balance of 
the APP award is represented by performance against personal 
objectives set by the Remuneration Committee. As a result, we 
have made APP awards to the Executive Directors of between 64% 
and 119% of salary. Details of each Executive Director’s APP award 
are set out on page 70. This is the first year of the new policy for 
maximum APP payments, with the maximum being reduced from 
150% of salary (for the 2013/14 awards) to 125%.

LTPP
2014 was the first year in which the maximum potential for the 
LTPP awarded during the year was increased in line with the new 
remuneration policy from 225% to 350% of salary for the Chief 
Executive and 200% to 300% of salary for the other Executive 
Directors. This is a three year plan and the performance 
outcomes will only be determined in July 2017. In 2014/15, Group 
RoE and value growth were both on target in relation to the 2014 
LTPP parameters, with UK RoE around stretch, and US RoE 
below threshold.

The LTPP that vested during 2014/15 was that awarded in 2011. 
This included three performance measures: adjusted EPS; 
relative total shareholder return (TSR); and UK and US returns. 
The EPS measure vested at 31%, reflecting EPS growth just above 
the threshold target for this measure. The TSR measure vested at 
98.3%, which reflects an annualised return to shareholders of 
18.9% over the period. The UK and US returns measures are 
expected to vest at 100% and 25.9% respectively, reflecting strong 
operational performance in the UK, including the first two years of 
RIIO, and the impact of rate base growth and higher winter related 
costs in the US. As a result, the 2011 LTPP vested at between 
46% and 66% for the Executive Directors. Details of each Executive 
Director’s vested LTPP are set out on pages 70 and 71.

Future targets
Details of future targets and historical performance are disclosed 
each year in respect of the LTPP. Details of historical performance 
against targets are disclosed each year in respect of the APP. 
We provide these details on pages 70 to 72 and page 74. Taking 
account of this year’s performance, as well as the challenges

Annual statement from the  
Remuneration Committee chairman
Overview
Last year, over 96% of shareholders voted to approve a new 
remuneration policy for National Grid. Although the policy is not 
subject to shareholder vote again this year, we have reprinted it 
on pages 62 to 68 for ease of reference. The new policy followed 
an extensive review by the Remuneration Committee to assess 
how the remuneration framework needed to change to reflect 
developments in National Grid’s business – the introduction of  
a new eight year regulatory framework in the UK (RIIO), and the 
continued evolution of our US business. 

National Grid’s shareholder returns are earned progressively 
through two main contributing factors. First, through careful 
management of long-term assets and their financing; and second, 
by building for future returns through a substantial, continuing and 
well-executed programme of long-term capital investment in 
regulated and non-regulated operations. Our aim was to make sure 
that shareholders’ and executives’ longer-term interests are clearly 
aligned through properly focused incentive plans and by requiring 
executives to have a significant shareholding in the Company. In 
summary, we concluded that:

•  there should be a significant weighting towards longer-term 
incentives and longer-term shareholding exposure for senior 
management through a reduction in the potential maximum 
Annual Performance Plan (APP) level, and an increase in the 
potential maximum Long Term Performance Plan (LTPP) level;
•  the bulk of remuneration should be paid in National Grid shares;
•  senior executives should be required to have a significant 

mandatory shareholding (500% of pre-tax salary for the CEO 
and 400% for other Executive Directors) and that no shares 
could be sold (except for meeting the tax on vesting) until the 
mandatory shareholding level was attained;

•   shares that vested under the LTPP, following the three year 
performance measurement period, had to be retained for 
a further two years, irrespective of whether the mandatory 
shareholding level had been attained; and

•   the metrics for LTPP performance should change to Return on 
Equity (RoE) and value growth. RoE provides a measurement  
of management’s performance in generating profit from the 
business, and value growth captures management’s longer-term 
performance in creating shareholder value.

We were clear that the new arrangements must only deliver higher 
rewards when executives had achieved a commensurately stronger 
performance. We believe that we have set threshold, target and 
stretch levels of performance accordingly. We also wanted to make 
sure that our commitment to increasing the annual dividend by at 
least RPI for the foreseeable future – an important element in 
shareholders’ total return – was linked to executive remuneration. 
The Committee, therefore, made it explicit that it had the power to 
reduce LTPP vesting if the Company failed to honour the dividend 
commitment, irrespective of the level of vesting resulting from the 
performance against the LTPP targets set by the Committee.

60

Corporate Governanceahead, after careful consideration the Committee has decided to 
retain the same weighting of performance metrics and the same 
targets for the 2015 LTPP as last year and the same framework of 
metrics for the 2015/16 APP awards. The Committee believes that 
the targets for these metrics set appropriately demanding levels for 
executive performance. For the 2015 LTPP, the maximum payout 
will require an average annual Group RoE of 12.5% and an average 
annual value growth of 12% over the three year performance 
period. We will again review performance against metrics next year 
to judge whether any changes should be made to the weighting 
of the metrics or to the targets underlying the incentive in 
future awards.

Executive Director shareholdings
Executive Directors are now required to build up and hold a 
significant shareholding in the Company (500% of gross salary  
for the CEO and 400% for the other Executive Directors). 
Steve Holliday’s current shareholding is significantly above his 
shareholding requirement. The other Executive Directors, due  
to their relatively short time in the role, have not yet reached their 
increased level of shareholding requirement. On current projections, 
Andrew Bonfield and John Pettigrew should reach their required 
shareholding in 2017 and 2018 respectively. As Dean Seavers was 
only appointed to the Board on 1 April 2015, he is expected to take 
somewhat longer to reach his required shareholding.

Executive Director changes 
Nick Winser stepped down from the Board at the 2014 AGM and 
will leave the Company at the end of July 2015 when his role will  
be redundant. Details of his termination payments are summarised 
on page 72. In October last year, it was announced that Tom King 
would also leave the Company at the end of March 2015 and 
would be succeeded as an Executive Director and President 
of National Grid’s US business by Dean Seavers. Tom King’s 
termination payments are also detailed on page 72. I confirm that 
all such payments to Nick Winser and to Tom King are in line with 
approved policy. 

Dean Seavers joined the Company on 1 December 2014, 
and joined the Board on 1 April 2015, with a starting salary of 
US$1,000,000. He will be eligible for a prorated APP in respect of 
2014/15 and also received an award of 300% of salary in respect of 
the 2014 LTPP. In addition to his starting package, he also received 
compensation for bonuses from his former employer that have 
been foregone amounting to US$250,000 paid on joining and a 
further US$250,000 to be paid one year later. He is a member of 
the US Defined Contribution Core Plan with Company contributions 
based on a percentage of salary and his APP award and a 401(k) 
plan match. All of these arrangements are in line with the approved 
policy on recruitment remuneration.

Salaries
For the year ahead, the Committee has awarded a salary increase 
of just below 1% to both Steve Holliday and Andrew Bonfield which 
is less than the 1.9% annual salary budget agreed for the 2015 
managerial salary review in the UK. Dean Seavers will not receive 
any salary increase from 1 June 2015 which reflects the decision 
to have a 0% annual salary budget for the 2015 managerial salary 
review in the US.

John Pettigrew joined the Board on 1 April 2014 with a starting 
salary of £475,000 and he did not receive any salary increase from 
1 June 2014. In line with the policy on recruitment remuneration, 
his salary was set below the market rate for equivalent roles. In the 
report last year, the Committee indicated that it would exercise its 
discretion in line with the policy to increase his salary towards 
market level by way of future increases in excess of those awarded 

to the wider workforce and inflation, subject to his performance. 
The Committee has decided to award him a 7% increase in salary 
from 1 June 2015 with further above inflation increases planned in 
the future to bring him closer to the market rate for his role, subject 
to his ongoing performance.

Conclusion
The Committee considers that the remuneration earned last year 
by Executive Directors is a fair reflection of the value achieved for 
shareholders. Their remuneration is, however, in a transitional 
phase since the APP outturn reflects a lower maximum potential 
(125% of salary versus 150% previously) while the level of LTPP 
vesting reflects both the previous policy limits and also the previous 
bases of measurement. This transitional phase will continue until 
2017 when the last element of the 2013 LTPP finally vests and the 
2014 LTPP (under the new policy) matures. We will report in detail 
on each element during this period to give shareholders as clear 
a view as is possible about the underlying performance of the new 
policy. This year the Committee is not seeking any changes to 
remuneration policy, so the only shareholder vote on remuneration 
is an advisory vote on the Directors’ Remuneration Report 
(Resolution 16). We believe we have correctly and fairly implemented 
the approved policy during the past year. We also believe that, 
while it is too early to be definitive, the new incentive arrangements 
that we initiated last year are beginning to prove their merits. On 
behalf of the Committee, I commend this report to you and ask 
for your support for the resolution at the Annual General Meeting.

Directors’ remuneration policy – approved by 
shareholders in 2014
The full Directors’ remuneration policy approved for three years 
from the date of the 2014 AGM held on 28 July 2014 is shown 
on pages 62 to 68 for ease of reference only. A shareholder vote 
on remuneration policy is not required in 2015. Please note 
that the information shown has been updated to take account of 
the fact that the policy is now approved and current rather than 
proposed. The tables showing the total remuneration opportunity 
on page 68 have also been updated to take account of Board 
departures and joiners and June 2015 salary levels. A copy of 
the remuneration policy is available on the Company website 
at investors.nationalgrid.com/reports/2013-14 (pages 60 to 66). 

There may be circumstances from time to time when the 
Committee will consider it appropriate to apply some judgement 
and exercise discretion in respect of the approved policy. This 
ability to apply discretion is highlighted where relevant in the 
policy, and the use of discretion will always be in the spirit of 
the approved policy.

The Committee will honour any commitments made to Directors 
before the policy outlined in this report came into effect.

Our peer group
The Committee benchmarks its remuneration policy against 
appropriate peer groups annually to make sure we remain 
competitive in the relevant markets. The primary focus for 
reward benchmarking is the FTSE 11-40 for UK-based Executive 
Directors and general industry and energy services companies 
with similar levels of revenue for US-based Executive Directors. 
These peer groups are considered appropriate for a large, 
complex, international and predominantly regulated business.

They are generally reviewed annually. Salary reviews take 
into account:

•  business and individual contribution;
•  the individual’s skills and experience;
•  scope of the role, including any changes 

in responsibility; and

•  market data in the relevant comparator group.

Purpose and link to strategy: to attract, motivate and retain high-calibre individuals,  
while not overpaying.

Performance metrics, weighting 
and time period applicable

Not applicable.

Maximum levels

No prescribed maximum 
annual increase.

Any increases are generally 
aligned to salary increases 
received by other Company 
employees and to market 
movement. Increases in excess 
of this may be made at the 
Committee’s discretion in 
circumstances such as a 
significant change in 
responsibility; progression 
in the role; and alignment 
to market level.

Benefits

Purpose and link to strategy: to provide competitive and cost-effective benefits to attract  
and retain high-calibre individuals.

Performance metrics, weighting 
and time period applicable

Not applicable.

Maximum levels

Benefits have no pre-determined 
maximum, as the cost of 
providing these varies from year 
to year. 

Participation in tax approved 
all-employee share plans is 
subject to limits set by the 
relevant tax authorities from time 
to time.

Operation

Benefits provided include:

•  company car or a cash alternative (UK only);
•  use of a driver when required;
•  private medical insurance;
•  life assurance;
•  personal accident insurance;
•  opportunity to purchase additional benefits under flexible 

benefits schemes available to all employees; and

•  opportunity to participate in the following HM Revenue & 

Customs (UK) or Internal Revenue Service (US) tax 
advantaged all-employee share plans:

Sharesave: UK employees may make monthly 
contributions from net salary for a period of 3 or 5 years. 
The savings can be used to purchase shares at a 
discounted price, set at the launch of each plan period.

Share Incentive Plan (SIP): UK employees may use 
gross salary to purchase shares. These shares are placed 
in trust.

Corporate GovernancePension

Purpose and link to strategy: to reward sustained contribution and assist attraction and retention.

Performance metrics, weighting 
and time period applicable

Not applicable.

Operation

Pension for a new Executive Director will reflect whether 
they are internally promoted or externally appointed.

If internally promoted:

•  retention of existing DB benefits without enhancement, 

except for capping of pensionable pay increases following 
promotion to Board; or

•  retention of existing UK DC benefits or equivalent cash in 

lieu; or

•  retention of existing US DC benefits plus 401(k) plan 

match, provided through 401(k) plan and non-qualified 
plans.

If externally appointed:

•  UK DC benefits or equivalent cash in lieu; or 
•  US DC benefits plus 401(k) plan match.

Andrew Bonfield, John Pettigrew and Dean Seavers are 
treated in line with the above policy.

Steve Holliday and Nick Winser are provided with final 
salary pension benefits. For service prior to 1 April 2013, 
pensionable pay is normally the base salary in the 
12 months prior to leaving the Company. For service from 
1 April 2013 increases to pensionable pay are capped at the 
lower of 3% or the increase in inflation. The pension scheme 
rules allow for indexed prior salaries to be used for all 
members. They participate in the unfunded scheme in 
respect of benefits in excess of the Lifetime Allowance.

Tom King participated in a qualified pension plan and in 
an Executive Supplemental Retirement Plan. These plans 
were non-contributory, cash balance and final average pay 
plans. Tom’s benefits included compensation to buy out 
entitlements from his former employer that were lost on 
recruitment to National Grid. 

In line with market practice, pensionable pay for UK-based 
Executive Directors includes salary only and for US-based 
Executive Directors it includes salary and APP award.

Maximum levels

UK DB: a maximum pension 
on retirement, at age 60, of two 
thirds final capped pensionable 
pay or up to one thirtieth accrual. 
On death in service, a lump sum 
of four times pensionable pay and 
a two thirds dependant’s pension 
is provided.

UK DC: annual contributions of 
30% of salary. Life assurance 
provision of four times 
pensionable salary and a 
spouse’s pension equal to one 
third of the Director’s salary are 
provided on death in service.

US DB: an Executive 
Supplemental Retirement Plan 
provides for an unreduced 
pension benefit at age 62 
(at age 55 in Tom King’s case). 
For retirements at age 62 with 
35 years of service, the pension 
benefit would be approximately 
two thirds of pensionable pay. 
Upon death in service, the 
spouse would receive 50% of 
the pension benefit (100% if the 
participant died while an active 
employee after the age of 55).

US DC: 9% of base salary plus 
APP with additional 401(k) plan 
match of up to 4%.

Annual  
Performance Plan

Purpose and link to strategy: to incentivise and reward the achievement of annual financial 
and strategic business targets and the delivery of annual individual objectives.

Maximum levels

The maximum award is 125% 
of salary.

Operation

Performance metrics and targets are agreed at the start of 
each financial year. Performance metrics are aligned with 
strategic business priorities. Targets are set with reference 
to the budget. Awards are paid in June.

For APP awards made in 2013/14, 50% of any award was 
deferred into shares in the Deferred Share Plan (DSP). The 
DSP has no performance conditions and vests after three 
years, subject to continued employment. These shares are 
subject to forfeiture for leavers in certain circumstances.

The DSP has been discontinued for APP awards made in 
respect of years from 2014/15. Instead 50% of awards are 
paid in shares, which (after any sales to pay tax) must be 
retained until the shareholding requirement is met, and in 
any event for two years after receipt. 

Awards are subject to clawback and malus provisions.

Performance metrics, weighting 
and time period applicable

A significant majority of the APP 
is based on performance against 
corporate financial measures, 
with the remainder based on 
performance against individual 
objectives. Individual objectives 
are role specific.

The Committee may use its 
discretion to set measures that 
it considers appropriate in each 
financial year and reduce the 
amount payable, taking account 
of significant safety or customer 
service standard incidents, 
environmental and governance 
issues.

The payout levels at threshold, 
target and stretch performance 
levels are 0%, 50% and 100% 
respectively.

Long Term  
Performance Plan

Purpose and link to strategy: to drive long-term performance, aligning Executive Director incentives 
to key strategic objectives and shareholder interests.

Operation

Awards of shares may be granted each year, with vesting 
subject to long-term performance conditions.

The performance metrics have been chosen as the 
Committee believes they reflect the creation of long-term 
value within the business. Targets are set each year with 
reference to the business plan.

Awards are subject to clawback and malus provisions. 
Notwithstanding the level of award achieved against the 
performance conditions, the Committee may use its 
discretion to reduce the amount vesting, and in particular 
will take account of compliance with the dividend policy.

Maximum levels

The maximum award for the CEO 
is 350% of salary and it is 300% 
of salary for the other Executive 
Directors.

For awards made between 
2011 and 2013, the maximum 
award for the CEO was 225% 
of salary and 200% for the other 
Executive Directors.

Performance metrics, weighting 
and time period applicable

For awards between 2011 and 
2013 the performance measures 
and weightings were:

•  adjusted EPS (50%) measured 

over three years;

•  TSR relative to the FTSE 100 
(25%) measured over three 
years; and

•  UK or US RoE relative to allowed 

regulatory returns (25%) 
measured over four years.

From 2014, the performance 
measures are:

•  value growth and Group RoE 
(for the CEO and Finance 
Director); and

•  value growth, Group RoE and 
UK or US RoE (for the UK and 
US Executive Directors 
respectively).

Maximum levels

For awards granted from 2014, participants must retain 
vested shares (after any sales to pay tax) until the 
shareholding requirement is met, and in any event for 
a further two years after vesting.

Performance metrics, weighting 
and time period applicable

All are measured over a three year 
period.

The weightings of these measures 
may vary year to year, but would 
always remain such that the value 
growth metric would never fall 
below a 25% weighting and never 
rise above a 75% weighting. 

Between 2011 and 2013, 25% of 
the award vested at threshold and 
100% at stretch, with straight-line 
vesting in between. From 2014, 
only 20% vests at threshold.

There are no maximum fee levels.

Not applicable.

The benefits provided to the 
Chairman are not subject to a 
predetermined maximum cost, 
as the cost of providing these 
varies from year to year.

NED fees (excluding those of the Chairman) are set by the 
Executive Committee in conjunction with the Chairman; the 
Chairman’s fees are set by the Committee.

Fee structure:

•  Chairman fee;
•  basic fee, which differs for UK- and US-based NEDs;
•  committee membership fee; 
•  committee chair fee; and
•  Senior Independent Director fee.

Fees are reviewed every year and are benchmarked against 
those in companies of similar scale and complexity.

NEDs do not participate in incentive or pension plans and, 
with the exception of the Chairman, are not eligible to 
receive benefits. The Chairman is covered by the 
Company’s private medical and personal accident 
insurance plans and receives a fully expensed car or cash 
alternative to a car, with the use of a driver, when required.

There is no provision for termination payments.

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Directors’ Remuneration Report continued

Shareholding requirement 
The requirement of Executive Directors to build up and hold a 
relatively high value of National Grid shares ensures they share 
a significant level of risk with shareholders and their interests 
are aligned.

The Company includes in its annual employee opinion survey 
questions on the appropriateness of the pay arrangements within 
the Company. It does not specifically invite employees to comment 
on the Directors’ remuneration policy but any comments made by 
employees are noted.

From 2014/15, Executive Directors are required to build up and 
retain shares in the Company. The level of holding required is 
500% of salary for the CEO and 400% of salary for the other 
Executive Directors.

Unless the shareholding requirement is met, Executive Directors 
will not be permitted to sell shares, other than to pay tax or in 
exceptional circumstances.

Differences in remuneration policy for all employees
The remuneration policy for the Executive Directors is designed 
with regard to the policy for employees across the Company as 
a whole. However, there are some differences in the structure 
of remuneration policy for the senior executives. In general, 
these differences arise from the development of remuneration 
arrangements that are market competitive for our various employee 
categories. They also reflect the fact that, in the case of the 
Executive Directors, a greater emphasis tends to be placed on 
performance-related pay in the market, in particular long-term 
performance-related pay.

All employees are entitled to base salary, benefits and pension. 
Many employees are eligible for an APP award based on Company 
and/or individual performance. Eligibility and the maximum 
opportunity available is based on market practice for the employee’s 
job band. In addition, around 350 senior management employees 
are eligible to participate in the LTPP.

The Company has a number of all-employee share plans that 
provide employees with the opportunity to become, and to think 
like, a shareholder. These plans include Sharesave and the SIP 
in the UK and the 401(k) and 423(b) plans in the US. Further 
information is provided on page 62.

Consideration of remuneration policy elsewhere  
in the Company
In setting the remuneration policy, the Committee considers the 
remuneration packages offered to employees across the Company. 
As a point of principle, salaries, benefits, pensions and other 
elements of remuneration are benchmarked regularly to ensure 
they remain competitive in the markets in which we operate. In 
undertaking such benchmarking, our aim is to be at mid-market 
level for all job bands, including those subject to union negotiation.

As would be expected, we have differences in pay and benefits 
across the business which reflect individual responsibility and there 
are elements of remuneration policy which apply to all, for example, 
flexible benefits and share plans.

When considering annual salary increases, the Committee reviews 
the proposals for salary increases for the employee population 
generally, as it does for any other changes to remuneration policy 
being considered. This will include a report on the status of 
negotiations with any trade union represented employees.

Policy on recruitment remuneration
Salaries for new Executive Directors appointed to the Board will be 
set in accordance with the terms of the approved remuneration 
policy in force at the time of appointment, and in particular will take 
account of the appointee’s skills and experience as well as the 
scope and market rate for the role.

Where appropriate, salaries may be set below market level initially, 
with the Committee retaining discretion to award increases in salary 
in excess of those of the wider workforce and inflation to bring 
salary to a market level over time, where this is justified by individual 
and Company performance.

Benefits consistent with those offered to other Executive Directors 
under the approved remuneration policy in force at the time of 
appointment will be offered, taking account of local market 
practice. The Committee may also agree that the Company will 
meet certain costs associated with the recruitment, for example 
legal fees, and the Committee may agree to meet certain relocation 
expenses or provide tax equalisation as appropriate.

Pensions for new Executive Directors appointed to the Board will 
be set in accordance with the terms of the approved remuneration 
policy in force at the time of appointment.

Ongoing incentive pay (APP and LTPP) for new Executive Directors 
will be in accordance with the approved remuneration policy in 
force at the time of appointment. This means the maximum APP 
award in any year would be 125% of salary and the maximum LTPP 
award would be 300% of salary (350% of salary for a new CEO).

For an externally appointed Executive Director, the Company may 
offer additional cash or share-based payments that it considers 
necessary to buy out current entitlements from the former 
employer that will be lost on recruitment to National Grid. Any such 
arrangements would reflect the delivery mechanisms, time horizons 
and levels of conditionality of the remuneration lost.

In order to facilitate buy-out arrangements as described above, 
existing incentive arrangements will be used to the extent possible, 
although awards may also be granted outside of these shareholder-
approved schemes if necessary and as permitted under the 
Listing Rules.

For an internally appointed Executive Director, any outstanding 
variable pay element awarded in respect of the prior role will 
continue on its original terms.

Fees for a new Chairman or Non-executive Director will be set in 
line with the approved policy in force at the time of appointment.

Please note that the information shown above is different to that 
contained in the approved policy as it has been updated to take 
account of Board departures and joiners during the year.

External appointments
The Executive Directors may, with the approval of the Board, 
accept one external appointment as a non-executive director of 
another company and retain any fees received for the appointment. 
Experience as a board member of another company is considered 
to be beneficial personal development, that in turn is of value to 
the Company.

Service contracts and policy on payment for loss of office 
In line with our policy, all Executive Directors have service contracts 
which are terminable by either party with 12 months’ notice. 

The contracts contain provisions for payment in lieu of notice, at the 
sole and absolute discretion of the Company. Such payments are 
limited to payment of salary only for the remainder of the notice 
period. In the UK such payments would be phased on a monthly 
basis, over a period no greater than 12 months, and the Executive 
Director would be expected to mitigate any losses where 
employment is taken up during the notice period. In the US, for 
tax purposes the policy is to make any payment in lieu of notice as 
soon as reasonably practicable, and in any event within two and a 
half months of the later of 31 December and 31 March immediately 
following the notice date. 

In the event of a UK Director being made redundant, statutory 
compensation would apply and the relevant pension plan rules 
may result in the early payment of an unreduced pension.

On termination of employment, no APP award would generally be 
payable and any DSP awards would generally lapse. However, the 
Committee has the discretion to deem an individual to be a ‘good 
leaver’, in which case an APP award would be payable on the 
termination date, based on performance during the financial year 
up to termination, and DSP awards would vest on the termination 
date. Examples of circumstances in which a Director would be 
treated as a ‘good leaver’ include redundancy, retirement, illness, 
injury, disability and death. Any APP award would be prorated and 
would be subject to performance achieved against the objectives 
for that year.

On termination of employment, outstanding awards under the 
share plans will be treated in accordance with the relevant plan 
rules approved by shareholders. Share awards would normally 
lapse. ‘Good leaver’ provisions apply at the Committee’s discretion 
and in specified circumstances, including redundancy, retirement, 
illness, injury, disability and death, where awards will be released 
to the departing Executive Director or, in the case of death, to their 
estate. Long-term share plan awards held by ‘good leavers’ may 
vest subject to performance measured at the normal vesting date 
and are prorated. Such awards would vest at the same time as for 
other participants.

The Chairman’s appointment is subject to six months’ notice by 
either party; for the other Non-executive Directors, notice is one 
month. No compensation is payable to Non-executive Directors 
if required to stand down. 

Copies of Directors’ service contracts and letters of appointment 
are available to view at the Company’s registered office.

1.  ‘Fixed pay’ for Andrew Bonfield, Steve Holliday and John Pettigrew consists of salary, pension and benefits in kind as provided under the remuneration policy. ‘Fixed pay’ for Dean Seavers 

consists of salary, the part of his pension that is aligned with salary (see footnote 4 below) and benefits in kind as provided under the remuneration policy.

2.  Salary is that to be paid in 2015/16, taking account of the increases that will be effective from 1 June 2015 shown on page 74.
3.  Benefits in kind are as shown in the single total figure of remuneration table for 2014/15 on page 69, except for Dean Seavers for whom benefits in kind are assumed to be $37,000.
4.  Pension is as shown in the single total figure of remuneration table for 2014/15 on page 69, except for Andrew Bonfield for whom pension is shown as 30% of salary and Dean Seavers, 

for whom pension is shown as 13% of salary plus 13% of APP. This is made up of a 9% Core Plan contribution and a 4% Company match to his 401(k) plan. The element of Dean’s pension 
that is aligned with salary is shown within ‘Fixed pay’ and the element of his pension that is aligned with APP is shown within ‘APP’.

5.  APP calculations are based on 125% of salary for the period 1 April 2015 to 31 March 2016. For Dean Seavers, APP also includes the part of his pension that is aligned with APP  

(see footnote 4 above).

6.  LTPP calculations are based on awards with a face value at grant of 350% of 1 June 2015 salary for Steve Holliday and 300% of 1 June 2015 salary for all other Executive Directors. 

They, therefore, exclude future share price movement.

7.  LTPP and APP payout is 50% for on target performance and the maximum is 100% for achieving stretch performance. 
8.  Dean Seaver’s remuneration opportunity has been converted at $1.58:£1.

Statement of consideration of shareholder views
The Committee considers all feedback received from shareholders throughout the year. While the Committee understands that not 
all shareholders’ views will be the same, we consult with our larger shareholders on a regular basis to understand their expectations 
with regard to executive remuneration issues and any changes in shareholder views in this regard. In 2013/14, we consulted larger 
shareholders on the proposed changes to remuneration policy. Shareholders were supportive of the direction of change proposed, 
particularly increasing holding periods for awards and retention thresholds. Several responses suggested a number of small changes 
and where possible the Committee reflected these changes in the proposals that were approved at the 2014 AGM.

1.  Base salaries were last increased on 1 June 2014. At this time Andrew Bonfield, Steve Holliday and Tom King all received salary increases of 2.5%, in line with the salary increase given to other 
employees of the Company. John Pettigrew joined the Board on 1 April 2014 and was not given a salary increase at 1 June 2014. Nick Winser was not given a salary increase at 1 June 2014, 
as he was stepping down from the Board at the 2014 AGM. Tom King’s annual salary was converted at $1.58:£1 in 2014/15 and $1.62:£1 in 2013/14.

2.  Benefits in kind include private medical insurance, life assurance, either a fully expensed car or a cash alternative to a car and the use of a driver when required. For Andrew Bonfield, 

Steve Holliday and John Pettigrew, it also includes the benefits of Sharesave options granted during the year. For Andrew Bonfield, a cash allowance in lieu of pension contributions is included 
within pension rather than benefits in kind.

3.  The APP value for 2013/14 is the full award before the 50% mandatory deferral into the DSP. 
4.  A portion of the 2011 LTPP award vested in July 2014, with the remainder due to vest in July 2015. The above value is based on the share price (855 pence) on the vesting date (1 July 2014) 
for that portion that vested on 1 July 2014, and the average share price over the three months from 1 January 2015 to 31 March 2015 (899 pence) for that portion due to vest on 1 July 2015. 
In the prior year the 2010 PSP award vested and entered a retention period which ended in June 2014. The above valuation is based on the share price (744 pence) on the vesting date 
(1 July 2013).

5.  The pension figure for Tom King is based on his accrued benefit at date of leaving. Tom is required to take his benefit from age 55 (2016) and, under the provisions of the plan, his pension will 

be reduced for early payment.

6.   John Pettigrew was appointed to the Board on 1 April 2014, and hence his single total figure of remuneration for 2013/14 was £nil.
7.   Nick Winser stood down from the Board on 28 July 2014. His salary, benefits in kind and APP for 2014/15 shown above are prorated to reflect qualifying service between 1 April and 28 July 
2014 during which time Nick was a member of the Board. The 2011 LTPP for 2014/15 shown above is not prorated, as this relates to the three-year period ended 30 June 2014, prior to Nick 
standing down from the Board. The 2011 LTPP only includes the EPS and TSR portion that vested during the year. The RoE portion is not included as Nick was not a Director at the end of the 
year. The RoE portion will be disclosed in the 2015/16 Remuneration Report under payments to past Directors. The pension for 2014/15 shown above represents pension earned by Nick over 
the full year to 31 March 2015, as required by BIS disclosure regulations.

performance and target and stretch performance.

2.  Adjusted EPS is amended for the impact of timing and actuarial assumptions on pensions and OPEBs.
3.  The UK RoE comprises the reported 13.7% plus a discretionary adjustment of 60bps to include the benefit of a one-off legal settlement.
4.  Nick Winser’s APP award for 2014/15 is prorated to reflect the period between 1 April and 28 July 2014 when he was a member of the Board.

Individual objectives
The individual performance objectives of the Executive Directors and Executive Committee for 2014/15 were set by reference to the 
Company’s overall strategic priorities for the year including building on our strong safety performance; the drive for business growth in the 
UK and US; delivery of operational excellence and improvement in overall Company performance and service to customers; promotion of 
new ideas to work more efficiently and effectively; strengthening the talent pipeline and keeping all our people fully engaged; working with 
external stakeholders to shape energy policy and embed sustainability into our decision making to preserve natural resources and focus 
on environmental issues. Measureable levels of threshold, target and stretch performance are agreed, paying out at 0%, 50% and 100% 
respectively. The following table indicates the primary area of focus of the individual performance objectives of the Executive Directors for 
2014/15, together with their overall performance against these objectives:

2014/15 LTPP performance (audited information)
The LTPP value included in the 2014/15 single total figure relates to vesting of the conditional LTPP award granted in 2011. Part of the 
award – that dependent on performance over the three years ending 31 March 2014 for the EPS measure (50% weighting) and over the 
three years ending 30 June 2014 for the TSR measure (25% weighting) – vested on 1 July 2014. The remaining 25% weighting of the 2011 
LTPP relates to the RoE measure. This is made up of the UK RoE measure for the UK Executive Directors, the US RoE measure for the US 
Executive Director and both the UK RoE measure and the US RoE measure in equal weightings for the CEO and Group Finance Director. 
The UK RoE measure is measured over the four years ending 31 March 2015 and the US RoE measure is measured over the four years 
ending 31 December 2014. However, the award does not vest until four years after the grant date, i.e. until 1 July 2015. The performance 
achieved against the performance targets, including the expected vesting percentage for the RoE measures, was:

1.  The UK-based Executive Directors participate in FPS, a salary sacrifice arrangement. Under FPS, the individual’s salary is reduced by an amount equal to the employee pension contribution 

that would have been paid into the scheme. An equivalent contribution is paid into the scheme by the employer. 

2.  For Steve Holliday, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £127,000 as at 31 March 2015. The increase to the 

accumulated lump sum, net of inflation, was £1,000 in the year to 31 March 2015. 

3.  For Nick Winser, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £316,000 as at 31 March 2015. The accumulated lump sum 

reduced by £6,000 in the year to 31 March 2015, after allowing for inflation.

4.   For John Pettigrew, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £428,000 as at 31 March 2015. The increase to the 

accumulated lump sum net of inflation was £63,000 in the year to 31 March 2015.

5.  For Tom King, the exchange rate as at 31 March 2015 was $1.49:£1 and as at 31 March 2014 was $1.67:£1. Through Tom King’s participation in the 401(k) plan in the US (a DC arrangement) 

the Company made contributions worth £8,076.

6.  For Steve Holliday, John Pettigrew and Nick Winser, the increase in accrued DB-type pension over the year shown above is net of inflation, as UK pensions in payment or deferment increase 
in line with inflation. For Tom King, the increase in accrued DB-type pension over the year shown above does not allow for inflation, as US pensions in payment or deferment do not increase 
in line with inflation.

7.   In accordance with BIS methodology, the pension benefit for Andrew Bonfield is calculated as the aggregate of contributions made to a DC-type pension plan (£nil) and cash in lieu of 

contributions to a DC-type pension plan (£218,000). In accordance with BIS disclosure regulations, the pension benefit for Steve Holliday, Tom King, John Pettigrew and Nick Winser is 
calculated as the increase in accrued DB-type pension over the year shown above multiplied by 20 plus the increase or less the decrease in the lump sum shown above, less the reduction 
in salary due to FPS plus total contributions made to DC-type pension plans. Each element is calculated separately and rounded to produce the numbers in the table above.

8.   There are no additional benefits in the event of early retirement.

Shareholder dilution
Where shares may be issued or treasury shares reissued to satisfy incentives, the aggregate dilution resulting from executive share-based 
incentives will not exceed 5% in any 10 year period. Dilution resulting from all incentives, including all-employee incentives, will not exceed 
10% in any 10 year period. The Committee reviews dilution against these limits regularly and under these limits the Company, as at 
31 March 2015, had headroom of 4.12% and 7.95% respectively.

Statement of Directors’ shareholdings and share interests (audited information)
The Executive Directors are required to build up and hold a shareholding from vested share plan awards. Deferred share plan awards are 
not taken into account for these purposes until the end of the deferral period. Shares are valued for these purposes at the 31 March 2015 
price, which was 865 pence per share ($64.61 per ADS) except for Nick Winser whose shares are valued at the 28 July 2014 share price 
of 879 pence per share. 

The following table shows how each Executive Director complies with the shareholding requirement and also the number of shares 
owned by the Non-executive Directors, including connected persons. For Philip Aiken, Maria Richter and Nick Winser, the shareholding 
is as at the date they stepped down from the Board. For all others it is as at 31 March 2015.

Corporate GovernanceNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Directors’ Remuneration Report continued

Performance graph and table 
This chart shows National Grid plc’s six year annual total shareholder 
return (TSR) performance against the FTSE 100 Index since 31 March 
2009. The FTSE 100 Index has been chosen because it is the widely 
recognised performance benchmark for large companies in the 
United Kingdom. Over the last four years, National Grid’s TSR has 
outperformed that of the FTSE 100 and underpins the pay shown for 
the Chief Executive in the table below, using current and previously 
published single total remuneration figures. The TSR level shown at 
31 March each year is the average of the closing daily TSR levels for 
the 30 day period up to and including that date. It assumes dividends 
are reinvested.

The table below shows how the percentage change in the CEO’s salary, benefits and APP between 2013/14 and 2014/15 compares with 
the percentage change in the average of each of those components of remuneration for non-union employees in the UK. The Committee 
views this group as the most appropriate comparator group, as the CEO is UK-based and this group excludes employees represented by 
trade unions, whose pay and benefits are negotiated with each individual union.

There will be no change to the implementation of the remuneration policy for 2015/16. Salary increases will normally be in line with the 
increase awarded to other employees in the UK and US, unless there is a change in role or responsibility. In line with the policy on recruitment 
remuneration, salaries for new directors may be set below market level initially and aligned to market level over time (provided the increase 
is merited by the individual’s contribution and performance).

Advisors to the Remuneration Committee
The Committee received advice during 2014/15 from independent remuneration consultants New Bridge Street (NBS), a trading name 
of Aon Hewitt Ltd (part of Aon plc). NBS were selected as advisors by the Committee from 1 August 2013 following a competitive 
tendering process.

Work undertaken by NBS included updating the Committee on trends in compensation and governance matters and advising the 
Committee in connection with benchmarking of the total reward packages for the Executive Directors and other senior employees. 
NBS are a member of the Remuneration Consultants Group and have signed up to that group’s Code of Conduct. The Committee is 
satisfied that any potential conflicts were appropriately managed. NBS does not provide any other advice or services to the Company. 
In the year to 31 March 2015 the Committee paid a total of £88,890 to NBS, with fees being charged on a time incurred basis. 

The Committee also received specialist advice from the following organisations:

•  Alithos Limited: provision of TSR calculations for the LTPP (£18,750 paid in 2014/15);
•  Linklaters LLP: advice relating to share schemes and to Directors’ service contracts as well as providing other legal advice to the 

Company (£82,330 paid in 2014/15); and

•  Towers Watson: advice relating to the benchmarking of the total reward packages for the Executive Directors and other senior 

employees (£74,450 paid in 2014/15).

The Committee reviews the objectivity and independence of the advice it receives from its advisors each year. It is satisfied that they 
all provided credible and professional advice.

The Committee considers the views of the Chairman on the performance and remuneration of the CEO; and of the CEO on the 
performance and remuneration of the other members of the Executive Committee. The Committee is also supported by the Group 
General Counsel & Company Secretary who acts as Secretary to the Committee, the Group HR Director, the Global Head of Reward 
and the Global Head of Pensions. No other advisors have provided significant services to the Committee in the year.

Introduction to the financial statements

We have continued to develop our presentational format to provide shareholders and users of these financial statements with additional 
information and guidance, and to make them easier to understand.

Throughout these financial statements we have provided plain English explanations of the disclosures and why they are important to the 
understanding of our financial performance and position. In places we have also highlighted ‘Our strategy in action’, drawing out the key 
elements of our business model (set out in the Strategic Report on pages 12 to 13), and showing how the disclosures reflect this strategy.

Audit opinions
We have two audit opinions on our financial statements, reflecting our dual listing on the London Stock Exchange and the New York 
Stock Exchange. Due to the different reporting requirements for each listing, our auditors are required to confirm compliance with each 
set of standards in a prescribed format. The audit opinion as required under our UK listing (starting on page 79) continues to provide 
more detail as to how our auditors have planned and completed their audit, as well as their views on significant matters they have noted 
and that were discussed by the Audit Committee.

Notes
Notes to the financial statements provide additional information required by statute, accounting standards or other regulations to assist 
in a more detailed understanding of the primary financial statements. In many notes we have included an accounting policy that describes 
how the transactions or balance in that note have been measured, recognised and disclosed. The basis of preparation section (note 1) 
provides details of accounting policies that apply to transactions and balances in general. There are also additional specific disclosure 
requirements due to our US listing which are included in the notes.

Unaudited commentary
We have presented with the financial statements certain analysis as part of the Strategic Report of our Annual Report. This approach 
provides a clearer narrative, a logical flow of information and reduces duplication. We have created a combined financial review, 
including a commentary on items within the primary statements, on pages 86 to 93. Unless otherwise indicated, all analysis provided in 
the financial statements is on a statutory IFRS basis. All information in ruled boxes styled in the same manner as this one does not form 
part of the audited financial statements. This has been further highlighted by including the word ‘unaudited’ at the start of each box 
header. Unaudited commentary boxes appear on pages 87 to 89, 91, 93, 99 to 100, 110, 112 and 125.

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Statement of Directors’ responsibilities

The Directors are responsible for preparing the Annual Report and 
Accounts, including the consolidated financial statements and the 
Company financial statements, the Directors’ Report, including the 
Remuneration Report and the Strategic Report, in accordance with 
applicable law and regulations.

Company law requires the Directors to prepare financial statements 
for each financial year. Under that law the Directors have prepared 
the consolidated financial statements in accordance with 
International Financial Reporting Standards (IFRS) as adopted by 
the European Union, and the Company financial statements and 
the Remuneration Report in accordance with applicable law and 
United Kingdom Accounting Standards (United Kingdom Generally 
Accepted Accounting Practice, UK GAAP). In preparing the 
consolidated financial statements, the Directors have also elected 
to comply with IFRS, issued by the International Accounting 
Standards Board (IASB). Under company law the Directors must 
not approve the financial statements unless they are satisfied that 
they give a true and fair view of the state of affairs of the Company 
on a consolidated and individual basis and of the profit or loss of 
the Company on a consolidated basis for that period.

In preparing these financial statements, the Directors are 
required to:

•  select suitable accounting policies and then apply them 

consistently;

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Company’s 
transactions and disclose with reasonable accuracy at any time the 
financial position of the Company on a consolidated and individual 
basis, and to enable them to ensure that the consolidated financial 
statements comply with the Companies Act 2006 and Article 4 of 
the IAS Regulation and the Company financial statements and the 
Remuneration Report comply with the Companies Act 2006. They 
are also responsible for safeguarding the assets of the Company 
and its subsidiaries and hence for taking reasonable steps for the 
prevention and detection of fraud and other irregularities.

The Directors are responsible for the maintenance and integrity 
of the Company’s website. Legislation in the United Kingdom 
governing the preparation and dissemination of financial 
statements may differ from legislation in other jurisdictions.

Having made the requisite enquiries, so far as the Directors in 
office at the date of the approval of this Report are aware, there is 
no relevant audit information of which the auditors are unaware and 
each Director has taken all reasonable steps to make themselves 
aware of any relevant audit information and to establish that the 
auditors are aware of that information.

Each of the Directors, whose names and functions are listed on 
page 43, confirms that:

•  make judgements and estimates that are reasonable 

•  to the best of their knowledge, the consolidated financial 

and prudent;

•  state that the consolidated financial statements comply with 

IFRS as issued by the IASB and IFRS adopted by the European 
Union and, with regard to the Company financial statements, 
that applicable UK Accounting Standards have been followed, 
subject to any material departures disclosed and explained in 
the financial statements; and

•  prepare the consolidated financial statements and Company 
financial statements on a going concern basis unless it is 
inappropriate to presume that the Company, on a consolidated 
and individual basis, will continue in business, in which case 
there should be supporting assumptions or qualifications 
as necessary.

statements and the Company financial statements, which have 
been prepared in accordance with IFRS as issued by the IASB 
and IFRS as adopted by the European Union and UK GAAP 
respectively, give a true and fair view of the assets, liabilities, 
financial position and profit of the Company on a consolidated 
and individual basis;

•  to the best of their knowledge, the Strategic Report contained 
in the Annual Report and Accounts includes a fair review of the 
development and performance of the business and the position 
of the Company on a consolidated and individual basis, together 
with a description of the principal risks and uncertainties that it 
faces; and

•  they consider that the Annual Report and Accounts, taken as 

a whole, is fair, balanced and understandable and provides the 
information necessary for shareholders to assess the Company’s 
position and performance, business model and strategy.

Report on the financial statements
Our opinion
In our opinion:

•  National Grid’s Group and Company financial statements (the 

‘financial statements’) give a true and fair view of the state of the 
Group’s and the Company’s affairs as at 31 March 2015 and of 
the Group’s profit and cash flows for the year then ended;
•  the Group financial statements have been properly prepared 

in accordance with International Financial Reporting Standards 
(IFRS) as adopted by the European Union;

•  the Company financial statements have been properly prepared 

in accordance with United Kingdom Generally Accepted 
Accounting Practice (UK GAAP); and

•  the financial statements have been prepared in accordance with 
the requirements of the Companies Act 2006 and, as regards 
the Group financial statements, Article 4 of the IAS Regulation.

Separate opinion in relation to IFRSs as issued by the IASB
As explained in the Basis of preparation to the financial 
statements, the Group, in addition to applying IFRSs as adopted 
by the European Union, has also applied IFRSs as issued by the 
International Accounting Standards Board (IASB).

In our opinion, the Group financial statements comply with IFRSs 
as issued by the IASB.

What we have audited
The financial statements, which are prepared by National Grid plc, 
comprise the following:

•  the Consolidated statement of financial position and 

Company balance sheet as at 31 March 2015;

•  the Consolidated income statement and Consolidated 

statement of comprehensive income for the year then ended;
•  the Consolidated cash flow statement for the year then ended;
•  the Consolidated statement of changes in equity for the year 

then ended;

•  the Consolidated and Company Basis of preparation; and
•  the notes to the Consolidated financial statements and the 
notes to the Company financial statements, which include 
explanatory and supplementary information.

Certain required disclosures, including Directors’ remuneration, 
required by the financial reporting framework have been presented 
elsewhere in the Annual Report and Accounts (the ‘Annual Report’), 
rather than in the notes to the financial statements. These are 
cross-referenced from the financial statements and are identified 
as audited.

The financial reporting framework that has been applied in the 
preparation of the Group financial statements is applicable law and 
IFRSs as adopted by the European Union. The financial reporting 
framework that has been applied in the preparation of the Company 
financial statements is applicable law and UK GAAP.

Overview of our audit approach
National Grid is listed on the London and New York stock exchanges 
and its principal activities are regulated electricity and gas operations 
in the UK and northeastern US. In the UK, National Grid’s activities 
are focused on gas and electricity transmission and gas distribution. 
National Grid’s business in the US includes gas and electricity 
distribution and electricity transmission as well as delivery of gas 
and electricity to end users across a number of states. National 
Grid also operates a number of other activities which include 
Grain LNG, Interconnectors, Metering and UK Property.

As a result, key focus areas for National Grid in both the UK and 
US are network investment and the associated financing, and 
maximising returns allowable under regulatory frameworks. These 
activities provide the context for our audit together with, in National 
Grid US, the ongoing work to improve business processes and 
financial controls.

Materiality
•  Overall group materiality: £132m which represents 4.6% of profit 

before tax, exceptional items and remeasurements.

Audit scope
•  UK Electricity Transmission, UK Gas Transmission, UK Gas 
Distribution and US Regulated required an audit of their 
complete financial information due to their size;
•  specific audit procedures on certain balances and 

transactions were also performed at four reporting units 
within Other activities; and

•  taken together, the territories and functions where we performed 
our audit work accounted for 96% of group revenues and 88% 
of group profit before tax.

Areas of focus
Event-driven:
•  US financial control environment.

Recurring:
•  Accuracy of capital expenditures.
•  Accuracy and valuation of treasury derivative transactions 

and application of hedge accounting.
•  Valuation of environmental provisions.
•  Accounting for net pension obligations.
•  Revenue recognition.

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Independent auditors’ report
to the Members of National Grid plc continued

Materiality
The scope of our audit was influenced by our application of 
materiality. We set certain quantitative thresholds for materiality. 
These, together with qualitative considerations, helped us to 
determine the scope of our audit and the nature, timing and extent 
of our audit procedures and to evaluate the effect of misstatements, 
both individually and on the financial statements as a whole.

Event-driven risks
Area of focus:
US financial control environment
The implementation of the US enterprise resource planning system 
in 2012/13 and associated changes to key processes and financial 
controls has had a significant impact on the reporting of financial 
information by the US Regulated business.

Based on our professional judgement, we determined materiality 
for the financial statements as a whole as follows:

Overall group materiality
£132m (2013/14: £126m).

How we determined it
4.6% of profit before tax, exceptional items and remeasurements.

Rationale for benchmark applied
We have chosen profit before tax, exceptional items and 
remeasurements because it is disclosed on the face of the 
Consolidated income statement as the consistent year on year 
measure for reporting performance. It excludes the non-recurring 
distorting impact of exceptional items and remeasurements.

We agreed with the Audit Committee that we would report 
to them misstatements identified during our audit above £6m 
(2013/14: £6m) as well as misstatements below that amount 
which in our view, warranted reporting for qualitative reasons.

The scope of our audit and our areas of focus
We conducted our audit in accordance with International 
Standards on Auditing (UK and Ireland) (‘ISAs (UK & Ireland)’). 
Our audit approach combined high reliance on controls over 
financial reporting where we considered them to be operating 
effectively as well as evidence gained from substantive testing.

We designed our audit by determining materiality and assessing 
the risks of material misstatement in the financial statements. 
In particular, we looked at where the Directors made subjective 
judgements, for example, in respect of significant accounting 
estimates that involved making assumptions and considering 
future events that are inherently uncertain. As in all of our audits, 
we also addressed the risk of management override of internal 
controls, including evaluating whether there was evidence of bias 
by the Directors that represented a risk of material misstatement 
due to fraud.

The risks of material misstatement that had the greatest effect on 
our audit, including the allocation of our resources and effort, are 
identified as ‘areas of focus’ below. We have also set out how we 
tailored our audit to address these specific areas in order to provide 
an opinion on the financial statements as a whole, and any 
comments we make on the results of our procedures should 
be read in this context. This is not a complete list of all risks 
identified by our audit.

In 2014/15, work has continued to improve the quality of processes 
and controls on a sustainable basis particularly in the areas of 
access controls, the financial statement close process, the quality 
of account reconciliations across all financial statement line items, 
analytical review, and revenue and receivables. However, the US 
control environment continues to be an area of focus due to the 
higher risk of error in the financial information reported by the 
US Regulated business.

How our audit addressed the area of focus:
To address the risk, a significant portion of both US and group 
senior audit team members’ time was spent developing our audit 
response to the issues within the US financial control environment, 
which we discussed with management and the Audit Committee.

We tailored our audit response as follows:

•  In those areas where a significant segregation of duties 

or access control risk was identified, additional procedures, 
including retrospective reviews of system access, were 
performed. This work identified no issues that impacted 
on our audit approach.

•  In areas of higher risk or where there were known issues, we 
increased our substantive testing sample sizes. Our testing 
identified a small number of potential adjustments which 
we reported to the Audit Committee, none of which was 
considered individually or in aggregate to be material to the 
financial statements.

•  As management was placing greater emphasis on account 
reconciliations as a key control, we increased the number of 
reconciliations tested and level of precision of our substantive 
testing of reconciliations. Our testing did not identify any 
adjustments of a level that required reporting to the Audit 
Committee.

•  In order to address the heightened risk of fraud as a result 
of weaker controls, we tested the design and operating 
effectiveness of journal review controls and found nothing 
that would cause us to believe these controls were not working 
as designed. We also tested journal entries based on a fraud 
risk assessment, with no material issues arising.

As noted above, whilst we did identify errors and reported these to 
the Audit Committee these were considered to be immaterial for 
adjustment in the Group financial statements.

Financial StatementsArea of focus:
Accuracy and valuation of treasury derivative transactions 
and application of hedge accounting
In order to fund its activities, at 31 March 2015 National Grid had 
total borrowings of £25.9 billion, of which £6.5 billion is denominated 
in currencies other than sterling or US dollars, which exposes it to 
foreign exchange and interest rate risk.

The Group has a large treasury operation and uses derivative 
financial instruments to manage foreign exchange and interest 
rate risks, primarily interest rate swaps and cross-currency 
interest rate swaps.

Whilst the majority of National Grid’s derivative contracts are 
straightforward, a number require more complex valuation 
approaches which include key assumptions over estimates of 
future interest, exchange rates and determination of appropriate 
discount rates to apply to future cash flows.

How our audit addressed the area of focus:
We tested the design and operating effectiveness of IT general 
controls including user access, change management and 
segregation of duties within the treasury management system 
and we found no material issues that would impact our planned 
audit approach.

We tested the design and operating effectiveness of key controls 
that relate to recording and valuing derivative transactions in the 
treasury management system. We also tested the accuracy and 
completeness of the information held within the system by agreeing 
to third-party confirmations and found no differences when 
compared with the system data.

Where management used models to value complex derivatives, 
we tested the appropriateness of the valuation methodology 
applied and the integrity of the models used, and noted no material 
issues. We also tested the accuracy of the contractual inputs and 
the appropriateness of key valuation inputs including price and 
discount rates without material issues. Where the Group entered 
into new significant contracts in the year, we tested the contracts 
and assumptions used to assess whether the accounting treatment 
adopted is in accordance with International Accounting Standard 39.

Recurring risks
Area of focus:
Accuracy of capital expenditures
A key area of focus for National Grid is network investment with 
total capital expenditure recognised within property, plant and 
equipment across the Group of £3.3 billion during 2014/15.

National Grid undertakes a number of activities of a similar nature 
which could contribute to operating expenditure (maintenance 
or network repair), or capital expenditure (network refurbishment 
or new assets). The key risk is that costs may not be correctly 
allocated across these four categories, given the impact on the 
accounting treatment.

In relation to the US Regulated business, there was a heightened 
risk that the controls over the classification of costs between 
operating expenditure and capital expenditure may not have been 
working effectively as a result of system complexities.

In addition, there are material adjustments that are required to 
translate local plant accounting records prepared under Generally 
Accepted Accounting Principles in the United States (US GAAP) to 
comply with IFRSs.

How our audit addressed the area of focus:
We assessed whether the Group’s accounting policies in relation 
to the capitalisation of expenditures complied with IFRSs. We 
tested the implementation of those policies through a combination 
of controls testing, including IT general controls over the plant 
accounting systems, and substantive testing of the supporting 
documentation behind the costs. We found no material issues 
that impacted our audit approach.

In the UK, we focused our testing on Electricity Transmission which 
is the largest area of UK capital expenditure. As part of our testing, 
we inspected contracts and underlying invoices to check that the 
classification between capital and operating expenditure was 
appropriate. Our testing did not identify any adjustments.

In the US Regulated business, our procedures included the 
identification of projects where the proportions of costs capitalised 
were different to those we would expect based on the nature of 
the work performed, and procedures around the appropriateness 
of capitalisation of payroll costs. We found no issues with regards 
to the capitalisation of payroll costs; however we did identify errors 
in the capitalisation of other costs, primarily contractor invoices. We 
reported these to the Audit Committee and they were considered 
to be immaterial for adjustment to the Group financial statements.

In respect of the translation of property, plant and equipment 
accounting records to IFRSs, management performed additional 
analysis which resulted in correcting adjustments. We tested this 
analysis to underlying accounting records, recalculations and 
supporting documentation. We did not identify any adjustments 
of a level that required reporting to the Audit Committee.

81

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Independent auditors’ report
to the Members of National Grid plc continued

How our audit addressed the area of focus:
We tested the significant judgements made by National Grid’s third-
party actuaries and assessed their independence and competence 
and found no issues that impacted our audit approach.

We compared the discount and inflation rates used in the valuation 
of the pension liability with our internally developed benchmarks. 
We compared the assumptions around salary increases and 
mortality with national and industry averages. All of the assumptions 
used fell within a range we found acceptable.

We obtained details of the measurement of fair value for assets with 
no observable inputs. Such assets were typically private equity or 
real estate fund investments for which we obtained audited financial 
statements in support of the valuations. We found no material 
issues from this testing.

Area of focus:
Revenue recognition
During 2014/15 National Grid has recognised revenue of £15.2 billion, 
the majority of which is related to regulated activities in the UK 
and US.

In the UK, National Grid’s revenue is governed by a number of price 
controls imposed by the UK regulator, Ofgem, which combined 
with the application of IFRSs means that revenue recognition 
involves limited judgement. The majority of revenue is derived from 
a small number of customers who settle within agreed terms.

In the US Regulated business, different services and locations are 
regulated by different authorities and are subject to numerous price 
controls. Unlike the UK, revenue is also earned through the supply of 
gas and electricity to end customers, which does involve judgement 
as a result of the estimate of accrued income for services delivered 
but not yet billed to these customers. This is determined using a 
long-established methodology within the Group.

As such, revenue recognition is not an area of significant risk for our 
audit but does require significant time and resource to audit due to 
its magnitude.

How our audit addressed the area of focus:
In the UK, we tested the design and operating effectiveness of 
key controls in relation to the recognition of revenue, with particular 
focus on controls over the setting of prices compared with those 
allowed by the Ofgem price controls and we found no material 
issues that impacted our audit approach.

We tested the revenue recognised to amounts invoiced to customers 
and the subsequent receipt of payment from those customers, with 
no material exceptions noted.

In the US Regulated business, in respect of transmission and 
other revenues not billed to end consumers, we selected individual 
transactions to test they were appropriately recorded as revenue in 
the correct period. We inspected the subsequent receipt of payment 
or confirmed amounts with customers where it was practical to do 
so. We also inspected regulator-approved tariffs to test that amounts 
charged were consistent with such tariffs. We found no material 
issues arising from our work.

Area of focus:
Valuation of environmental provisions
Over time National Grid has acquired, owned and operated a 
number of businesses that have created an environmental impact 
that will require remediation. This is particularly significant in the 
US partly as a result of National Grid’s exposure to certain 
‘Superfund’ sites (very large sites where the US Regulated 
business and other parties are jointly responsible for the 
remediation). At 31 March 2015 the total liability on a discounted 
basis in respect of environmental provisions is £1.2 billion, of 
which £0.9 billion relates to the US Regulated business.

Estimating environmental provisions requires significant judgement 
in determining the form of remediation and the timing and value 
of projected cash flows associated with it, including the impact of 
regulation, accuracy of the site surveys, unexpected contaminants, 
transportation costs, the impact of alternative technologies and 
changes in the discount rate.

How our audit addressed the area of focus:
In the US and UK, National Grid uses external and internal experts 
to help determine the total expenditure required to remediate sites. 
As part of the audit we obtained and inspected these experts’ 
reports and assessed their independence and competence and 
we found no issues that impacted our audit approach.

For material sites and a sample of other sites, we corroborated 
information on the nature of each of these sites to National Grid’s 
underlying site usage records. In addition, to assess the reliability 
of the experts’ estimates, we compared previous estimates against 
actual spend for sites which have been remediated, without 
material issue.

We also tested other inputs into the calculation by reference 
to publicly available information where appropriate and noted 
no exceptions.

We inspected responses to our confirmation requests from 
National Grid’s legal advisors in order to identify any issues 
related to the valuation of the Group’s exposure to environmental 
remediation costs and noted no issues.

In order to assess the reasonableness of management’s discount 
rate assumptions we compared these with our internally developed 
benchmarks and were satisfied these are within our acceptable 
range.

Area of focus:
Accounting for net pension obligations
National Grid provides defined pension and other post-retirement 
benefits to employees in the UK and US through a number of 
schemes. At 31 March 2015, National Grid’s gross defined benefit 
obligation is £29.7 billion which is offset by scheme assets of 
£26.4 billion.

The valuation of the pension liability requires significant judgement 
and technical expertise in choosing appropriate assumptions. 
Changes to the key assumptions including salary increases, 
inflation, discount rates and mortality can have a material impact 
on the calculation of the liability.

The pension plan assets also include a number of investments for 
which there is no observable input to the fair value (i.e. no quoted 
market price). The valuation technique used to measure the fair 
value of these assets is inherently more uncertain than assets with 
observable fair value inputs.

82

Financial StatementsFor US utility revenues billed to end consumers, we selected 
samples of rate classes to test that customer rates were properly 
updated in the billing systems, and that rate types were assigned 
to customers consistent with the type of customer and (where 
appropriate) the volume of usage. We also selected samples of 
customer bills and tested that such bills were paid by customers 
and were consistent with the regulator-approved rate plans. 
For those bills selected that were outstanding at the end of the 
year, we confirmed the balance with customers, and tested 
amounts to subsequent cash receipts where no customer 
confirmation was received.

In respect of unbilled revenue we tested management’s 
assumptions in relation to consumption by reference to historical 
data as well as specific current year factors, including weather 
patterns. In so doing, we did not note any material issues.

How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed 
enough work to be able to give an opinion on the financial 
statements as a whole, taking into account the geographic 
structure of the Group, the accounting processes and controls, 
and the industry in which the Group operates.

We identified that UK Electricity Transmission, UK Gas 
Transmission, UK Gas Distribution and the US Regulated business 
required an audit of their complete financial information due to 
their size. As the Group has separate finance functions for head 
office, the UK and US operations which each maintain their own 
accounting records and controls and report to Group through an 
integrated consolidation system, we used component auditors 
within PwC UK and PwC US who are familiar with the local laws 
and regulations to perform this audit work.

Where the work was performed by component auditors, we 
determined the level of involvement we needed to have in the audit 
work at those locations to be able to conclude whether sufficient 
appropriate audit evidence had been obtained as a basis for our 
opinion on the Group financial statements as a whole. In performing 
this assessment, and in particular given the US issues in our areas 
of focus, the Group team visited the US on a number of occasions 
for meetings with our US team and the US Regulated business. 
This was supported by regular conference calls throughout the 
year. We also held regular calls and meetings with our UK 
component teams.

The Group consolidation, financial statement disclosures and 
tax and treasury related activities are audited by the Group team 
using specialists where appropriate. Taken together, the territories 
and functions where we performed our audit work accounted for 
96% of Group revenues and 88% of Group profit before tax. 
The Group team retains overall responsibility for the audit of the 
financial statements.

Going concern
Under the Listing Rules we are required to review the Directors’ 
statement, set out on page 54, in relation to going concern. 
We have nothing to report having performed our review.

As noted in the Directors’ statement, the Directors have concluded 
that it is appropriate to prepare the financial statements using the 
going concern basis of accounting. The going concern basis 
presumes that the Group and Company have adequate resources 
to remain in operation, and that the Directors intend them to do so, 
for at least one year from the date the financial statements were 
signed. As part of our audit we have concluded that the Directors’ 
use of the going concern basis is appropriate.

However, because not all future events or conditions can be 
predicted, these statements are not a guarantee as to the Group’s 
and Company’s ability to continue as a going concern.

Other required reporting
Consistency of other information
Companies Act 2006 opinion
In our opinion, the information given in the Strategic Report and 
the Directors’ Report for the financial year for which the financial 
statements are prepared is consistent with the financial statements.

ISAs (UK & Ireland) reporting
Under ISAs (UK & Ireland) we are required to report to you if, 
in our opinion:

•  Information in the Annual Report is:
  –  materially inconsistent with the information in the audited 

financial statements; or

  –  apparently materially incorrect based on, or materially 

inconsistent with, our knowledge of the Group and Company 
acquired in the course of performing our audit; or

  – otherwise misleading.

We have no exceptions to report arising from this responsibility.

•  The statement given by the Directors on page 78, in accordance 
with provision C.1.1 of the UK Corporate Governance Code 
(the ‘Code’), that they consider the Annual Report taken as 
a whole to be fair, balanced and understandable and provides 
the information necessary for members to assess the Group’s 
performance, business model and strategy is materially 
inconsistent with our knowledge of the Group acquired in the 
course of performing our audit.

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Independent auditors’ report
to the Members of National Grid plc continued

Adequacy of accounting records and information and 
explanations received
Under the Companies Act 2006 we are required to report to 
you if, in our opinion:

•  we have not received all the information and explanations 

we require for our audit; or

•  adequate accounting records have not been kept by the 

Company, or returns adequate for our audit have not been 
received from branches not visited by us; or

•  the Company financial statements and the part of the 
Directors’ Remuneration Report to be audited are not 
in agreement with the accounting records and returns.

We have no exceptions to report arising from this responsibility. 

Directors’ remuneration
Directors’ Remuneration Report – Companies Act 2006 opinion
In our opinion, the part of the Directors’ Remuneration Report 
to be audited has been properly prepared in accordance with 
the Companies Act 2006.

Other Companies Act 2006 reporting
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. We have no exceptions to report 
arising from these responsibilities.

Corporate Governance statement
Under the Listing Rules we are required to review the part of the 
Corporate Governance statement relating to the Company’s 
compliance with 10 provisions of the Code. We have nothing to 
report having performed our review.

Responsibilities for the financial statements
and the audit
Our responsibilities and those of the Directors
As explained more fully in the Statement of Directors’ responsibilities 
set out on page 78, the Directors are responsible for the preparation 
of the 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 financial 
statements in accordance with applicable law and ISAs (UK & 
Ireland). Those standards require us to comply with the Auditing 
Practices Board’s Ethical Standards for Auditors.

This report, including the opinions, has been prepared for and only 
for the Company’s members as a body in accordance with Chapter 
3 of Part 16 of the Companies Act 2006 and for no other purpose. 
We do not, in giving these opinions, accept or assume responsibility 
for any other purpose or to any other person to whom this report is 
shown or into whose hands it may come save where expressly 
agreed by our prior consent in writing.

What an audit of financial statements involves
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 and the 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.

We primarily focus our work in these areas by assessing the 
Directors’ judgements against available evidence, forming our 
own judgements, and evaluating the disclosures in the financial 
statements.

We test and examine information, using sampling and other 
auditing techniques, to the extent we consider necessary to 
provide a reasonable basis for us to draw conclusions. We obtain 
audit evidence through testing the effectiveness of controls, 
substantive procedures or a combination of both.

In addition, we read all the financial and non-financial information 
in the Annual Report to identify material inconsistencies with the 
audited financial statements and to identify any information that is 
apparently materially incorrect based on, or materially inconsistent 
with, the knowledge acquired by us in the course of performing the 
audit. If we become aware of any apparent material misstatements 
or inconsistencies we consider the implications for our report.

Financial StatementsReport of Independent Registered Public Accounting Firm
to the Board of Directors and Shareholders of National Grid plc

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 (i) pertain to 
the maintenance of records that, in reasonable detail, accurately 
and fairly reflect the transactions and dispositions of the assets of 
the company; (ii) 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 authorisations of management 
and directors of the company; and (iii) provide reasonable assurance 
regarding prevention or timely detection of unauthorised 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.

Audit opinion for Form 20-F
In our opinion, the accompanying consolidated statement of 
financial position and the related consolidated income statement, 
consolidated statement of comprehensive income, consolidated 
cash flow statement and consolidated statement of changes in 
equity, present fairly, in all material respects, the financial position 
of National Grid plc and its subsidiaries at 31 March 2015 and 
31 March 2014, and the results of their operations and their cash 
flows for each of the three years in the period ended 31 March 
2015 in conformity with International Financial Reporting Standards 
as issued by the International Accounting Standards Board and in 
conformity with International Financial Reporting Standards as 
adopted by the European Union.

Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of 
31 March 2015, based on criteria established in Internal Control 
– Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO). 
The Company’s management is responsible for these financial 
statements, for maintaining effective internal control over financial 
reporting and for its assessment of the effectiveness of internal 
control over financial reporting, included in the Additional 
Information section appearing on page 173 of the 2015 Annual 
Report and Accounts.

Our responsibility is to express opinions on these financial 
statements and on the Company’s internal control over financial 
reporting based on our integrated 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 audits to obtain reasonable 
assurance about whether the financial statements are free of 
material misstatement and whether effective internal control over 
financial reporting was maintained in all material respects. Our 
audits of the financial statements included examining, on a test 
basis, evidence supporting the amounts and disclosures in the 
financial statements, assessing the accounting principles used 
and significant estimates made by management, and evaluating 
the overall financial statement presentation. Our audit of internal 
control over financial reporting included obtaining an understanding 
of internal control over financial reporting, assessing the risk that 
a material weakness exists, and testing and evaluating the design 
and operating effectiveness of internal control based on the assessed 
risk. Our audits also included performing such other procedures 
as we considered necessary in the circumstances. We believe 
that our audits provide a reasonable basis for our opinions.

Financial StatementsUnaudited commentary on the consolidated income statement

The consolidated income statement shows all revenue earned 
and costs incurred in the year, with the difference being the 
overall profit for the year.

Finance costs for the year ended 31 March 2015 included 
exceptional debt redemption costs of £131m and a loss of £34m 
on financial remeasurements, relating to net losses on derivative 
financial instruments.

Exceptional tax for 2014/15 of £78m primarily represents tax credits 
on the exceptional items and remeasurements described above.

Adjusted earnings and EPS
The following chart shows the five year trend in adjusted profit 
attributable to equity shareholders of the parent (adjusted earnings) 
and adjusted earnings per share. See page 186 for a reconciliation 
of adjusted basic EPS to EPS.

Adjusted EPS

1.   Adjusted earnings and adjusted EPS are attributable to equity shareholders of the parent.

The above earnings performance translated into adjusted EPS 
growth in 2014/15 of 4.6p (9%).

In accordance with IAS 33, all earnings per share and adjusted 
earnings per share amounts for comparative periods have been 
restated for shares issued via scrip dividends.

Exchange rates
Our financial results are reported in sterling. Transactions for 
our US operations are denominated in dollars, so the related 
amounts that are reported in sterling depend on the dollar to 
sterling exchange rate.

If 2013/14 results had been translated at 2014/15 exchange 
rates, revenue, adjusted operating profit and operating profit 
reported in sterling would have been £212m, £25m and £32m 
higher respectively.

Revenue
Revenue for the year ended 31 March 2015 increased by £392m 
to £15,201m. This increase was driven by higher revenues in our 
UK Electricity Transmission business, reflecting increases in 
allowed Transmission Owner revenues, and higher core allowances 
and pass-through costs in UK Gas Transmission. Revenues in our 
UK Gas Distribution business were slightly lower as a result of 
changes in allowed revenues for replacement expenditure (repex). 
Our US Regulated businesses revenues were also lower, as a 
result of the end of the LIPA Management Services Agreement 
(MSA) last year, partially offset by revenue increases from existing 
rate plans, including capex trackers, together with additional 
income from gas customer growth and the impact of the 
strengthening US dollar.

Operating costs
Operating costs for the year ended 31 March 2015 of £11,421m 
were £347m higher than the prior year. This increase in costs 
included a £154m year on year impact of changes in exceptional 
items, remeasurements and stranded cost recoveries, which is 
discussed below. Excluding exceptional items, remeasurements 
and stranded cost recoveries, operating costs were £193m higher, 
principally due to: increases in controllable costs, including the 
impact of inflation and additional costs incurred in the US to 
improve data quality and bring regulatory filings up to date; higher 
US bad debt costs following last year’s exceptionally cold winter; 
and higher depreciation and amortisation as a result of continued 
investment programmes. These cost increases were partly offset 
by a reduction in spend on US financial systems implementation 
and stabilisation upgrades, with the project completing in the first 
half of this year.

Net finance costs
For the year ended 31 March 2015, net finance costs before 
exceptional items and remeasurements were £75m lower than 
2013/14 at £1,033m, mainly as a result of lower average gross 
debt through the year, lower RPI in the UK and refinancing debt 
at lower rates.

Tax
The tax charge on profit before exceptional items, remeasurements 
and stranded cost recoveries was £114m higher than 2013/14. 
This was mainly due to higher profits before tax and the non-
recurrence of one-off items that benefited the prior year.

Exceptional items, remeasurements and stranded 
cost recoveries
Operating profit for the year ended 31 March 2015 included an 
£83m loss (2013/14: £16m gain) on remeasurement of commodity 
contracts. The year ended 31 March 2014 also included a net 
£55m gain on exceptional items, including a net gain on the LIPA 
MSA transition in the US of £254m; restructuring costs of £136m, 
primarily in the UK as we reorganised certain parts of our business 
to deliver under the new RIIO price controls; and a £79m provision 
for the demolition of UK gas holders that are no longer required.

Unaudited commentary on consolidated statement of comprehensive income

The consolidated statement of comprehensive income records 
certain items as prescribed by the accounting rules. For us, 
the majority of the income or expense included here relates to 
movements in actuarial assumptions on pension schemes and 
the associated tax impact. These items are not part of profit for 
the year, yet are important to allow the reader to gain a more 
comprehensive picture of our performance as a whole.

Remeasurements of net retirement benefit 
obligations
We had a net loss after tax of £472m (2013/14: net gain of £313m) 
on our pension and other post-retirement benefit schemes which 
is due to changes in key assumptions made in the valuation 
calculation of pension liabilities and differences between the 
expected and actual pension asset returns.

Exchange adjustments
Adjustments are made when we translate the results and net 
assets of our companies operating outside the UK, as well as 
debt we have issued in foreign currencies. The net movement 
for the year resulted in a gain of £175m (2013/14: £158m loss).

Net (losses)/gains in respect of cash flow hedges
The value of derivatives held to hedge cash flows is impacted by 
changes in expected interest rates and exchange rates. The net 
loss for the year was £154m (2013/14: £63m gain).

Financial StatementsUnaudited commentary on consolidated statement of financial position

The consolidated statement of financial position shows all of 
the Group’s assets and liabilities at the year end. As a capital-
intensive business, we have significant amounts of physical 
assets and corresponding borrowings.

Goodwill and other intangible assets
Goodwill and intangibles increased by £684m to £5,947m as at 
31 March 2015. This increase primarily relates to foreign exchange 
movements of £602m and software additions of £207m, partially 
offset by software amortisation of £121m.

Property, plant and equipment
Property, plant and equipment increased by £3,544m to £40,723m 
as at 31 March 2015. This was principally due to capital expenditure 
of £3,263m on the renewal and extension of our regulated networks 
and foreign exchange movements of £1,703m, offset by depreciation 
of £1,361m in the year. See page 22 for further details of our 
capital expenditure.

Investments and other non-current assets
Investments in joint ventures and associates, financial and other 
investments and other non-current assets have increased by  
£6m to £728m. This is primarily due to a decrease in investments 
in joint ventures of £33m, which includes dividends received of 
£79m, partially offset by our share of post-tax results for the year 
of £46m, more than offset by an increase in available-for-sale 
investments of £46m.

Inventories and current intangible assets, and trade 
and other receivables
Inventories and current intangible assets, and trade and other 
receivables have increased by £53m to £3,176m as at 31 March 
2015. This is due to an increase in inventories and current 
intangible assets of £72m, offset by a net decrease in trade and 
other receivables of £19m. The £19m decrease consists of an 
increase in foreign exchange of £211m due to the stronger US 
dollar against sterling and a decrease in the underlying balances of 
£229m, reflecting collection of large prior year balances, including 
LIPA MSA and Superstorm Sandy re-insurance receivables.

Trade and other payables
Trade and other payables have increased by £261m to £3,292m, 
primarily due to foreign exchange movements of £161m and an 
increase in VAT liability following a change in regulations on 
wholesale gas and electricity trading.

Current tax balances
Current tax balances have decreased by £33m to £124m as at 
31 March 2015. This is primarily due to the tax payments made 
in 2014/15 being only partially offset by a smaller current year 
tax charge.

Deferred tax balances
Deferred tax balances have increased by £215m to £4,297m as 
at 31 March 2015. This was primarily due to the impact of the 
£299m deferred tax credit on actuarial losses (a £172m tax charge 
in 2013/14) being offset by the impact of the reduction in the UK 
statutory tax rate, foreign exchange movements of £203m and the 
reduction in prior year charges.

Provisions and other non-current liabilities
Provisions (both current and non-current) and other non-current 
liabilities increased by £168m to £3,654m as at 31 March 2015.

Total provisions increased by £90m in the year. The underlying 
movements include additions of £105m relating to an increase 
to the provision for the estimated environmental restoration and 
remediation costs for a number of sites and other provision increases 
of £57m, together with foreign exchange movements of £133m, 
offset by utilisation of £209m in relation to all classes of provisions.

Net debt
Net debt is the aggregate of cash and cash equivalents, current 
financial and other investments, borrowings, and derivative 
financial assets and liabilities. See further analysis with the 
consolidated cash flow statement on page 92.

Net pension and other post-retirement obligations
A summary of the total UK and US assets and liabilities and the

The principal movements in net obligations during the year include 
net actuarial losses of £771m and employer contributions of £508m. 
Net actuarial losses include actuarial losses on plan liabilities of 
£2,746m arising as a consequence of increases in the UK real 
discount rate and the nominal discount rate in the US. This is 
partially offset by actuarial gains of £2,154m arising on plan assets.

Further information on our pension and other post-retirement 
obligations can be found in notes 22 and 29 to the consolidated 
financial statements.

Off balance sheet items
There were no significant off balance sheet items other than the 
contractual obligations shown in note 30(b) to the consolidated 
financial statements, and the commitments and contingencies 
discussed in note 27.

Through the ordinary course of our operations, we are party 
to various litigation, claims and investigations. We do not expect 
the ultimate resolution of any of these proceedings to have a 
material adverse effect on our results of operations, cash flows 
or financial position.

Financial StatementsUnaudited commentary on the consolidated cash flow statement

The consolidated cash flow statement shows how the cash 
balance has moved during the year. Cash inflows and outflows 
are presented to allow users to understand how they relate to 
the day-to-day operations of the business (Operating activities); 
the money that has been spent or earned on assets in the 
year, including acquisitions of physical assets or other 
businesses (Investing activities); and the cash raised from 
debt or share issues and other loan borrowings or repayments 
(Financing activities).

Cash flows from our operations are largely stable when viewed 
over the longer term. Our electricity and gas transmission and 
distribution operations in the UK are subject to multi-year rate 
agreements with regulators. In the UK, we have largely stable 
inter-year cash flows. However, in the US our short-term cash 
flows are dependent on the price of gas and electricity and the 
timing of customer payments. The regulatory mechanisms for 
recovering costs from customers can result in significant cash 
flow swings from year to year. Changes in volumes in the US, 
for example as a consequence of abnormally mild or extreme 
weather can affect cash flows, particularly in the winter months.

For the year ended 31 March 2015, cash flow from operations 
increased by £931m to £5,350m.

Changes in working capital improved by £360m over the prior 
year, principally in the US (£441m) due to the collection of high 
winter 2014 billings and other settlements including Hurricane 
Sandy re-insurance claims and LIPA receipts. Cash outflows 
relating to exceptional items were £133m lower, as the prior year 
included reorganisation costs in the UK and LIPA MSA transition 
costs in the US.

Net capital expenditure
Net capital expenditure in the year of £3,274m was £155m higher 
than the prior year. This was a result of higher spend in our 
US regulated businesses, reflecting a record year of investment, 
partially offset by lower spend in our UK regulated businesses.

Net interest paid
Net interest paid and exceptional finance costs in 2014/15 were 
£941m, £75m higher than 2013/14 due to £152m debt redemption 
cash outflows.

Tax paid
Tax paid in the year to 31 March 2015 was £343m, £57m lower 
than prior year. This reflected repayments received in the US 
during the period.

Dividends paid
Dividends paid in the year ended 31 March 2015 amounted to 
£1,271m. This was £212m higher than 2013/14, reflecting the 
increase in the final dividend for the year ended 31 March 2014 
paid in August 2014, together with a lower average scrip dividend 
take-up in the year.

Other cash movements
Other cash flows principally arise from dividends from joint 
ventures and movements in treasury shares, including the cost 
of repurchasing shares as part of the share buyback programme 
(£338m).

Non-cash movements
The non-cash movements are predominantly due to the 
strengthening of the US dollar against sterling, resulting in 
movements in foreign exchange arising on net debt held in 
currencies other than sterling. In the year, the dollar strengthened 
from $1.67 at 31 March 2014 to $1.49 at 31 March 2015.

Other non-cash movements are from changes in fair values of 
financial assets and liabilities and interest accretions and accruals.

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Notes to the consolidated financial statements
– analysis of items in the primary statements

1. Basis of preparation and recent accounting developments

Accounting policies describe our approach to recognising and measuring transactions and balances in the year. Accounting policies 
applicable across the financial statements are shown below. Accounting policies that are specific to a component of the financial 
statements have been incorporated into the relevant note.

This section also shows areas of judgement and key sources of estimation uncertainty in these financial statements. In addition, we 
summarise new EU endorsed accounting standards, amendments and interpretations and whether these are effective in 2015 or later 
years, explaining how significant changes are expected to affect our reported results.

National Grid’s principal activities involve the transmission and distribution of electricity and gas in Great Britain and northeastern US. 
The Company is a public limited liability company incorporated and domiciled in England, with its registered office at 1-3 Strand, 
London WC2N 5EH.

The Company has its primary listing on the London Stock Exchange and is also quoted on the New York Stock Exchange.

These consolidated financial statements were approved for issue by the Board of Directors on 20 May 2015. 

These consolidated financial statements have been prepared in accordance with International Accounting Standards (IAS) and International 
Financial Reporting Standards (IFRS) and related interpretations as issued by the IASB and IFRS as adopted by the EU. They are prepared 
on the basis of all IFRS accounting standards and interpretations that are mandatory for periods ended 31 March 2015 and in accordance 
with the Companies Act 2006 applicable to companies reporting under IFRS and Article 4 of the EU IAS Regulation. The 2014 and 2013 
comparative financial information has also been prepared on this basis.

The consolidated financial statements have been prepared on an historical cost basis, except for the recording of pension assets and 
liabilities, the revaluation of derivative financial instruments and certain commodity contracts and investments classified as available-for-sale.

The consolidated financial statements have been prepared on a going concern basis. The going concern basis presumes that the Group 
has adequate resources to remain in operation, and that the Directors intend it to do so, for at least one year from the date the financial 
statements are signed. Further details of the Directors’ assessment are set out on page 54.

These consolidated financial statements are presented in pounds sterling, which is also the functional currency of the Company.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts 
of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the 
reporting period (see accounting policy C).

A. Basis of consolidation
The consolidated financial statements incorporate the financial statements of the Company and its subsidiaries, together with a share of 
the results, assets and liabilities of jointly controlled entities (joint ventures) and associates using the equity method of accounting, where 
the investment is carried at cost plus post-acquisition changes in the share of net assets of the joint venture or associate, less any 
provision for impairment.

A subsidiary is defined as an entity controlled by the Company. Control is achieved where the Company has the power to affect the 
returns of an entity to which it is exposed or to which it has rights.

Losses in excess of the consolidated interest in joint ventures and associates are not recognised, except where the Company or its 
subsidiaries have made a commitment to make good those losses.

Where necessary, adjustments are made to bring the accounting policies used in the individual financial statements of the Company, 
subsidiaries, joint ventures and associates into line with those used by the Company in its consolidated financial statements under IFRS. 
Intercompany transactions are eliminated.

The results of subsidiaries, joint ventures and associates acquired or disposed of during the year are included in the consolidated income 
statement from the effective date of acquisition or up to the effective date of disposal, as appropriate.

Acquisitions are accounted for using the acquisition method, where the purchase price is allocated to the identifiable assets acquired and 
liabilities assumed on a fair value basis and the remainder recognised as goodwill.

94

Financial Statements1. Basis of preparation and recent accounting developments continued

B. Foreign currencies
Transactions in currencies other than the functional currency of the Company or subsidiary concerned are recorded at the rates of 
exchange prevailing on the dates of the transactions. At each reporting date, monetary assets and liabilities that are denominated in foreign 
currencies are retranslated at closing exchange rates. Non-monetary assets are not retranslated unless they are carried at fair value.

Gains and losses arising on the retranslation of monetary assets and liabilities are included in the income statement, except where the 
adoption of hedge accounting requires inclusion in other comprehensive income – note 15.

On consolidation, the assets and liabilities of operations that have a functional currency different from the Company’s functional currency 
of pounds sterling, principally our US operations that have a functional currency of dollars, are translated at exchange rates prevailing 
at the reporting date. Income and expense items are translated at the average exchange rates for the period where these do not differ 
materially from rates at the date of the transaction. Exchange differences arising are classified as equity and transferred to the consolidated 
translation reserve.

C. Areas of judgement and key sources of estimation uncertainty
The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts 
of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the 
reporting period. Actual results could differ from these estimates. Information about such judgements and estimations is contained in 
the notes to the financial statements, and the key areas are summarised below.

Areas of judgement that have the most significant effect on the amounts recognised in the financial statements are as follows:

•  the categorisation of certain items as exceptional items and the definition of adjusted earnings – notes 4 and 7; and
•  energy purchase contracts as being for normal purchase, sale or usage – note 27.

IFRS provides certain options available within accounting standards. Choices we have made, and continue to make, include the following:

•  Presentational formats: we use the nature of expense method for our income statement and aggregate our statement of financial 
position to net assets and total equity. In the income statement, we present subtotals of total operating profit, profit before tax and 
profit from continuing operations, together with additional subtotals excluding exceptional items, remeasurements and stranded 
cost recoveries. Exceptional items, remeasurements and stranded cost recoveries are presented separately on the face of the 
income statement.

•  Customer contributions: contributions received prior to 1 July 2009 towards capital expenditure are recorded as deferred income 

and amortised in line with the depreciation on the associated asset.

•  Financial instruments: we normally opt to apply hedge accounting in most circumstances where this is permitted. For net investment 

hedges, we have chosen to use the spot rate method, rather than the alternative forward rate method.

Key sources of estimation uncertainty that have significant risk of causing a material adjustment to the carrying amounts of assets and 
liabilities within the next financial year are as follows:

•  review of residual lives, carrying values and impairment charges for other intangible assets and property, plant and equipment 

– notes 10 and 11;

•  estimation of liabilities for pensions and other post-retirement benefits – notes 22 and 29;
•  valuation of financial instruments and derivatives – notes 15 and 30;
•  revenue recognition and assessment of unbilled revenue – note 2; and
•  environmental and decommissioning provisions – note 23.

In order to illustrate the impact that changes in assumptions could have on our results and financial position, we have included sensitivity 
analysis in note 33.

New IFRS accounting standards and interpretations adopted in 2014/15
The following standards, interpretations and amendments, issued by the IASB and by the IFRS Interpretations Committee (IFRIC), are 
effective for the year ended 31 March 2015. None of the pronouncements has had a material impact on the Company’s consolidated 
results or assets and liabilities for the year ended 31 March 2015.

•  IFRIC 21 ‘Levies’;
•  amendments to IAS 32 ‘Financial Instruments: Presentation’ in respect of offsetting financial assets and financial liabilities;
•  amendments to IFRS 10 ‘Consolidated Financial Statements’, IFRS 12 ‘Disclosure of Interests in Other Entities’ and IAS 27 

‘Separate Financial Statements’ in respect of investment entities;

•  amendments to IAS 36 ‘Impairment of Assets’ in respect of recoverable amount disclosures for non-financial assets; and
•  amendments to IAS 39 ‘Financial Instruments: Recognition and Measurement’, in respect of novation of derivatives and 

continuation of hedge accounting.

95

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Notes to the consolidated financial statements
– analysis of items in the primary statements continued

1. Basis of preparation and recent accounting developments continued

New IFRS accounting standards and interpretations not yet adopted
The Company enters into a significant number of transactions that fall within the scope of IFRS 9 ‘Financial Instruments’, effective for 
periods beginning after 1 January 2018. We are assessing the likely impact of this standard on the Company’s financial statements.

IFRS 15 ‘Revenue from Contracts with Customers’ was issued by the IASB in May 2014. Subject to EU endorsement, it is effective for 
accounting periods beginning on or after 1 January 2017. The new standard provides enhanced detail on the principle of recognising 
revenue to reflect the transfer of goods and services to customers at a value which the Company expects to be entitled to receive.

The Group has completed an initial impact assessment of the new standard by completing a survey of all businesses identifying the likely 
impact of IFRS 15. This was a tailored questionnaire based on the known impacts of the new standard on power and utility companies. 
Whilst no material differences were identified as part of the questionnaire process, further follow-up work will be required to determine the 
impact, if any, on certain revenue items including, but not limited to, variable consideration contracts, take or pay arrangements and 
performance obligations where multiple goods or services are provided in individual contracts. 

Other standards and interpretations or amendments thereto which have been issued, but are not yet effective, are not expected to have 
a material impact on the Company’s consolidated financial statements.

2. Segmental analysis

This note sets out the financial performance for the year split into the different parts of the business (operating segments). We monitor 
and manage the performance of these operating segments on a day-to-day basis.

Our strategy in action
We own a portfolio of businesses that range from businesses with high levels of investment and growth (such as UK Electricity 
Transmission) to cash generative developed assets with minimal investment requirements (such as National Grid Metering, included 
within Other activities).

We generate 95% of our revenue from our regulated operating segments in the UK and US. We work with our regulators to obtain 
agreements that balance the risks we face with the opportunity to deliver reasonable returns for our investors. When investing in 
Other activities we aim to leverage our core capabilities to deliver higher returns for investors.

Our regulated businesses earn revenue for the transmission, distribution and generation services they have provided during the year. 
In any one year, the revenue recognised may differ from that allowed under our regulatory agreements and any such timing differences 
are adjusted through future prices. Our Other activities earn revenue in line with their contractual terms.

Revenue primarily represents the sales value derived from the generation, transmission and distribution of energy, together with the sales 
value derived from the provision of other services to customers. It excludes value added (sales) tax and intra-group sales.

Revenue includes an assessment of unbilled energy and transportation services supplied to customers between the date of the last meter 
reading and the year end. This is estimated based on historical consumption and weather patterns.

Where revenue exceeds the maximum amount permitted by a regulatory agreement, adjustments will be made to future prices to reflect 
this over-recovery. No liability is recognised, as such an adjustment relates to the provision of future services. Similarly no asset is recognised 
where a regulatory agreement permits adjustments to be made to future prices in respect of an under-recovery.

We present revenue and the results of the business analysed by operating segment, based on the information the Board of Directors uses 
internally for the purposes of evaluating the performance of operating segments and determining resource allocation between operating 
segments. The Board of Directors is National Grid’s chief operating decision-making body (as defined by IFRS 8 ‘Operating Segments’) 
and assesses the performance of operations principally on the basis of operating profit before exceptional items, remeasurements and 
stranded cost recoveries (see note 4).

There have been no changes to our reporting structure for the year ended 31 March 2015.

96

Financial Statements2. Segmental analysis continued

The following table describes the main activities for each operating segment:

UK Electricity Transmission 

High voltage electricity transmission networks in Great Britain.

UK Gas Transmission

UK Gas Distribution 

US Regulated 

The gas transmission network in Great Britain and UK LNG storage activities.

Four of the eight regional networks of Great Britain’s gas distribution system. 

Gas distribution networks, electricity distribution networks and high voltage electricity 
transmission networks in New York and New England and electricity generation facilities 
in New York.

Other activities primarily relate to non-regulated businesses and other commercial operations not included within the above segments, 
including: the Great Britain-France electricity interconnector; UK based gas metering activities; UK property management; a UK LNG 
import terminal; US LNG operations; US unregulated transmission pipelines; together with corporate activities.

Sales between operating segments are priced considering the regulatory and legal requirements to which the businesses are subject. 
The analysis of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US 
geographical areas.

Financial StatementsUnaudited commentary on the results of our principal operations by segment

As a business, we have three measures of operating profit that are 
used on a regular basis and disclosed in this Annual Report.

Other operating costs were also £17m higher, including a £13m 
provision for decommissioning the Avonmouth LNG plant.

Statutory operating profit: This is operating profit as calculated 
under International Financial Reporting Standards (IFRS). Statutory 
operating profit by segment is shown in note 2 on page 98.

Capital investment remained around the same level as last year 
at £184m.

Adjusted operating profit: Adjusted operating profit (business 
performance) excludes items that if included could distort 
understanding of our performance for the year and the comparability 
between periods. Further details of items that are excluded in 
adjusted operating profit are shown in note 4 on page 103.

Regulatory financial performance: This is particularly relevant 
for our UK operations and is a measure of operating profit that 
reflects the impact of the businesses’ regulatory arrangements 
when presenting financial performance.

Reconciliations between statutory and adjusted operating profit 
can be found on page 186. Reconciliations between adjusted 
operating profit and regulatory financial performance for UK 
Electricity Transmission, UK Gas Transmission and UK Gas 
Distribution can be found on page 100.

Commentary on segmental adjusted operating 
profit results

We have summarised the results of our principal operating 
segments here by segment to provide direct reference to 
the results as disclosed in note 2. This analysis has been 
prepared based on adjusted operating profit (operating profit 
before exceptional items, remeasurements and stranded cost 
recoveries) as set out in note 2(b).

UK Electricity Transmission
For the year ended 31 March 2015, revenue in the UK Electricity 
Transmission segment was £367m higher at £3,754m, and 
adjusted operating profit increased by £150m to £1,237m.

Net regulated income after pass-through costs was £230m higher, 
principally reflecting increases in allowed Transmission Owner 
revenues this year and a £43m benefit relating to legal settlements. 
This was partially offset by under-recoveries of allowed revenue 
in the year of £89m compared with under-recoveries of £60m in 
the prior year. Regulated controllable costs were £14m higher 
due to inflation, organisational change costs and additional tower 
maintenance costs. Depreciation and amortisation was £33m 
higher reflecting the continued capital investment programme 
(investment in the year was £1,074m). Other costs were £4m 
higher than prior year.

UK Gas Transmission
Revenue in the UK Gas Transmission segment increased by £81m 
in 2014/15 to £1,022m and adjusted operating profit increased by 
£20m to £437m.

Net regulated income after pass-through costs was £42m higher 
due to earned gas permit and constraints management incentives. 
In addition, under-recoveries of allowed revenue in the year of £18m 
were £3m favourable to last year’s under-recoveries of £21m. 
Partially offsetting the revenue gains, regulated controllable costs 
were £8m higher, mainly as a result of additional system operator 
costs relating to EU work and some organisation change costs. 

UK Gas Distribution
UK Gas Distribution revenue decreased by £31m in 2014/15 
to £1,867m, and adjusted operating profit decreased by £78m 
to £826m.

Net regulated income after pass-through costs was £11m lower, 
reflecting changes in allowed revenues for replacement expenditure 
(repex). Timing differences reduced net revenues by a further 
£16m, with £13m over-recoveries in 2014/15, compared with a 
£29m over-recovery in the prior year. Regulated controllable costs 
were £22m higher primarily due to inflation and some organisation 
change costs. Depreciation and amortisation was £15m higher 
reflecting the continued capital investment programme 
(investment in the year was £498m). Other costs were £14m 
higher, reflecting a provision for additional asset protection costs.

US Regulated
Revenue in our US Regulated businesses was £54m lower in 
2014/15 at £7,986m, while adjusted operating profit increased 
by £39m to £1,164m.

The stronger dollar increased operating profit in the year by £30m. 
Excluding the impact of foreign exchange, net regulated income 
increased by £81m, reflecting increased revenue from existing rate 
plans, including capex trackers, together with additional income 
from gas customer growth, partially offset by the impact of the 
end of LIPA management services activities (MSA) in December 
2013. In addition, over-recoveries of allowed revenues in the year 
of £30m were £20m favourable to last year’s over-recoveries of 
£10m. Regulated controllable costs increased by £17m excluding 
the impact of foreign exchange, as a result of increased gas leak 
and compliance work and additional costs incurred to improve 
data quality and bring regulatory filings up to date, partly offset 
by the cessation of costs associated with the LIPA MSA activities. 
Bad debt costs were £62m higher excluding the impact of foreign 
exchange, following last year’s exceptionally cold winter. There 
were no major storms affecting our operations in the years ended 
31 March 2014 and 2015.

Our capital investment programme continues in the US, with a 
further £1,501m invested in 2014/15, including gas leak reduction 
programmes and electricity capacity and reinforcement work.

Other activities
Revenue in Other activities increased by £26m to £762m in the 
year ended 31 March 2015. Adjusted operating profit was £68m 
higher at £199m. 

Operating profit in the French interconnector was £18m higher as 
a result of strong auction revenues this year. In the US, corporate 
and other activities losses were £63m lower, mainly as a result 
of our finance system upgrade completing in the first half of this 
year. Capital investment in our Other activities was £33m higher 
at £213m.

Commentary on UK regulated financial performance

The regulated financial performance calculation provides a 
measure of the performance of the regulated operations before 
the impacts of interest and taxation. It adjusts reported operating 
profit under IFRS to reflect the impact of the businesses’ 
regulatory arrangements when presenting financial performance.

Adjustments in calculating regulatory financial performance
The principal adjustments from reported operating profit to UK 
regulated financial performance are:

Movement in UK regulatory ‘IOUs’: Revenue related to 
performance in one year may be recovered in later years. Revenue 
may be recovered in one year but be required to be returned to 
customers in future years. IFRS recognises these revenues when 
they flow through invoices to customers and not in the period to 
which they relate.

Performance RAV: UK performance efficiencies are in part 
remunerated by the creation of additional RAV which is expected 
to result in future earnings under regulatory arrangements.

Pension adjustment: Cash payments against pension deficits 
in the UK are recoverable under regulatory contracts.

3% RAV indexation: Future UK revenues expected to be set 
using an asset base adjusted for inflation. This will be billed in 
future periods and recognised under IFRS at that time.

UK deferred taxation adjustment: Future UK revenues are 
expected to recover cash taxation cost including the unwinding 
of deferred taxation balances created in the current year.

Regulatory depreciation: US and UK regulated revenues include 
allowance for a return of regulatory capital in accordance with 
regulatory assumed asset lives. This return does not form part 
of regulatory profit.

Fast/slow money adjustment: The regulatory remuneration 
of costs incurred is split between in year revenue allowances 
and the creation of additional RAV. This does not align with the 
classification of costs as operating costs and fixed asset additions 
under IFRS accounting principles.

UK Electricity Transmission
Regulated financial performance for UK Electricity Transmission 
increased to £1,232m from £1,066m, up 16%. The year on year 
movement reflected the higher opening regulated asset value 
and the higher achieved operational return on equity. There 
was also a one-off benefit of £56m from legal settlements. 
These were partially offset by a reduced price control ‘tracker’ 
cost of debt allowance.

UK Gas Transmission
Regulated financial performance for UK Gas Transmission 
increased to £648m from £552m, up 17%. This reflected improved 
operational return on equity, mainly as a result of incentive 
performance, and the increase in underlying revenues associated 
with increased regulated asset value. This was partly offset by 
lower allowed cost of debt (2.72% real compared with 2.92% real 
in 2013/14).

1.   The audit fees for the year ended 31 March 2014 have been restated to reflect the final audit fee following completion of the statutory audit process.
2.  Audit fees in each year represent fees for the audit of the Company’s financial statements and regulatory reporting for the years ended 31 March 2015, 2014 and 2013, and the review of 

interim financial statements for the six month periods ended 30 September 2014, 2013 and 2012 respectively.

3.  Other services supplied represent fees payable for services in relation to other statutory filings or engagements that are required to be carried out by the auditors. In particular, this includes 

fees for reports under section 404 of the US Public Company Accounting Reform and Investor Protection Act of 2002 (Sarbanes-Oxley) and audit reports on regulatory returns.

4. There were no audit related fees as described in Item 16C(b) of Form 20-F.
5. Tax fees include amounts charged for tax compliance, tax advice and tax planning. 
6.  All other fees include amounts relating to market research on the metering industry and sundry services, all of which have been subject to approval by the Audit Committee. Total other fees 

for the year ended 31 March 2015 were £0.4m (2014: £0.9m; 2013: £1.5m).

In addition, fees of £0.2m were incurred in 2015 in relation to the audits of the pension schemes of the Company (2014: £0.1m; 2013: £0.1m).

Subject to the Company’s Articles of Association and the Companies Act 2006, the Audit Committee is solely and directly responsible for 
the approval of the appointment, reappointment, compensation and oversight of the Company’s independent auditors. It is our policy that 
the Audit Committee must approve in advance all non-audit work in excess of £50,000 to be performed by the independent auditors to 
ensure that the service will not compromise auditor independence. The Committee has delegated the approval in advance for all non-audit 
work below this level to the Finance Director. Certain services are prohibited from being performed by the external auditors under the 
Sarbanes-Oxley Act 2002.

Financial Statements4. Exceptional items, remeasurements and stranded cost recoveries

To monitor our financial performance, we use a profit measure that excludes certain income and expenses. We call that measure 
‘business performance’ or ‘adjusted profit’. We exclude items from business performance because, if included, these items could 
distort understanding of our performance for the year and the comparability between periods. This note analyses these items, which 
are included in our results for the year but are excluded from business performance.

Our financial performance is analysed into two components: business performance, which excludes exceptional items, remeasurements 
and stranded cost recoveries; and exceptional items, remeasurements and stranded cost recoveries. Business performance is used 
by management to monitor financial performance as it is considered that it improves the comparability of our reported financial 
performance from year to year. Business performance subtotals are presented on the face of the income statement or in the notes 
to the financial statements.

Items of income or expense that are considered by management for designation as exceptional items include such items as significant 
restructurings, write-downs or impairments of non-current assets, significant changes in environmental or decommissioning provisions, 
integration of acquired businesses, gains or losses on disposals of businesses or investments and significant debt redemption costs 
as a consequence of transactions such as significant disposals or issues of equity.

Costs arising from restructuring programmes include redundancy costs. Redundancy costs are charged to the income statement in 
the year in which a commitment is made to incur the costs and the main features of the restructuring plan have been announced to 
affected employees.

Remeasurements comprise gains or losses recorded in the income statement arising from changes in the fair value of commodity 
contracts and of derivative financial instruments to the extent that hedge accounting is not achieved or is not effective. These fair 
values increase or decrease because of changes in commodity and financial indices and prices over which we have no control. 

Stranded cost recoveries represent the recovery, through charges to electricity customers in upstate New York and New England, 
of historical generation-related costs, related to generation assets that are no longer owned by National Grid. Such costs have been 
recovered from customers as permitted by regulatory agreements, which was completed by 31 March 2013.

1.   No exceptional restructuring costs have been incurred in the year ended 31 March 2015. Restructuring costs for 2014 included: costs related to the continued restructuring of our UK 

operations in preparedness to deliver RIIO, other transformation-related initiatives in the UK and US and an associated software impairment for licences that will no longer be used. For 
the year ended 31 March 2013, restructuring costs included: costs for the restructuring of our UK operations of £66m in preparedness for delivering RIIO; costs for transformation-related 
initiatives in the UK and US of £31m; and a credit of £10m for the release of restructuring provisions in the UK recognised in prior years. 

2.  No further provision (2014: £79m) has been made for the demolition of non-operational gas holders in the UK.
3.   For the year ended 31 March 2014, a net gain of £254m was recognised. This included a pension curtailment and settlement (£214m) for employees who transferred to a new employer 
following the cessation of the Management Services Agreement (MSA) with the Long Island Power Authority (LIPA) on 31 December 2013. There was also a gain of £142m following the 
extinguishment of debt obligations of £98m and a £56m cash payment received, in compensation for the Company forgiving an historical pension receivable and carrying charges. These 
gains were offset by transition costs and other provisions incurred to effect the transition. 

4.  During the year ended 31 March 2014, £16m was received following the sale to a third party of a settlement award which arose as a result of a legal ruling in 2008. 
5.  For the year ended 31 March 2013, we recognised a gain of £3m on the disposal of two subsidiaries in New Hampshire. 
6.   Remeasurements – commodity contracts represent mark-to-market movements on certain physical and financial commodity contract obligations in the US. These contracts primarily relate 
to the forward purchase of energy for supply to customers, or to the economic hedging thereof, that are required to be measured at fair value and that do not qualify for hedge accounting. 
Under the existing rate plans in the US, commodity costs are recoverable from customers although the timing of recovery may differ from the pattern of costs incurred.

7.  For the year ended 31 March 2013, stranded cost recoveries of £14m substantially represented the release of an unutilised provision recognised in a prior period. 
8.   Represents costs arising from a liability management programme. We have reviewed and restructured the Group debt portfolio following the commencement of the RIIO price controls 
in 2013 and the slow down in our planned short term UK capital investment programme as the industry assesses the impact of EMR. This resulted in a bond repurchase programme with 
a notional value of £924m.

9.   Remeasurements – net (losses)/gains on derivative financial instruments comprise (losses)/gains arising on derivative financial instruments reported in the income statement. These exclude 
gains and losses for which hedge accounting has been effective, which have been recognised directly in other comprehensive income or which are offset by adjustments to the carrying 
value of debt. The tax charge in the year includes a credit of £1m (2014: £nil; 2013: £1m) in respect of prior years.

10.  The Finance Act 2013 enacted reductions in the UK corporation tax rate from 23% to 21% from 1 April 2014, and from 21% to 20% from 1 April 2015. Other UK tax legislation also reduced 

the UK corporation tax rate in prior periods (2013: from 24% to 23%). These reductions have resulted in decreases to UK deferred tax liabilities in these periods.

11.  The exceptional tax charge in the prior year arose from a net increase in US state income tax rates. Effective from 1 April 2014, the state income tax rate for Massachusetts regulated utilities 

increased from 6.5% to 8% and, effective from 1 April 2016, the state income tax rate for New York will decrease from 7.1% to 6.5%.

Financial Statements5. Finance income and costs

This note details the interest income generated by our financial assets and interest expense incurred on our financial liabilities. It also 
includes the expected return on our pensions and other post-retirement assets, which is offset by the interest payable on pensions 
and other post-retirement obligations and presented on a net basis. In reporting business performance, we adjust net financing costs 
to exclude any net gains or losses on derivative financial instruments included in remeasurements. In addition, the current year debt 
redemption costs have been treated as exceptional (see note 4).

1.   Interest on funding attributable to assets in the course of construction in the current year was capitalised at a rate of 3.8% (2014: 4.5%; 2013: 4.4%). In the UK, capitalised interest qualifies 
for a current year tax deduction with tax relief claimed of £24m (2014: £32m). In the US, capitalised interest is added to the cost of plant and qualifies for tax depreciation allowances.
2.  Includes a net foreign exchange gain on financing activities of £636m (2014: £268m gain; 2013: £32m loss) offset by foreign exchange gains and losses on derivative financial instruments 

measured at fair value.

3.  Includes a net gain on instruments designated as fair value hedges of £219m (2014: £183m loss; 2013: £67m gain) offset by a net loss of £162m (2014: £205m gain; 2013: £50m loss) arising 

from fair value adjustments to the carrying value of debt.

6. Tax

Tax is payable in the territories where we operate, mainly the UK and the US. This note gives further details of the total tax charge and 
tax liabilities, including current and deferred tax. The current tax charge is the tax payable on this year’s taxable profits. Deferred tax 
is an accounting adjustment to provide for tax that is expected to arise in the future due to differences in the accounting and tax bases 
of profit.

The tax charge for the period is recognised in the income statement, the statement of comprehensive income or directly in equity, 
according to the accounting treatment of the related transaction. The tax charge comprises both current and deferred tax.

Current tax assets and liabilities are measured at the amounts expected to be recovered from or paid to the tax authorities. The tax 
rates and tax laws used to compute the amounts are those that have been enacted or substantively enacted by the reporting date.

The calculation of the Group’s total tax charge involves a degree of estimation and judgement, and management periodically evaluates 
positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and establishes 
provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

Deferred tax is provided for using the balance sheet liability method and is recognised on temporary differences between the carrying 
amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit.

Deferred tax liabilities are generally recognised on all taxable temporary differences and deferred tax assets are recognised to the extent 
that it is probable that taxable profits will be available against which deductible temporary differences can be utilised. However, deferred 
tax assets and liabilities are not recognised if the temporary differences arise from the initial recognition of goodwill or from the initial 
recognition of other assets and liabilities in a transaction (other than a business combination) that affects neither the accounting nor the 
taxable profit or loss.

Deferred tax liabilities are recognised on taxable temporary differences arising on investments in subsidiaries and jointly controlled entities 
except where the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will 
not reverse in the foreseeable future.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised, based 
on the tax rates and tax laws that have been enacted or substantively enacted by the reporting date.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that 
sufficient taxable profits will be available to allow all or part of the deferred tax asset to be recovered. Unrecognised deferred tax assets 
are reassessed at each reporting date and are recognised to the extent that it has become probable that future taxable profits will allow 
the deferred tax asset to be recovered.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax 
liabilities and when they relate to income taxes levied by the same tax authority and the Company and its subsidiaries intend to settle 
their current tax assets and liabilities on a net basis.

Deferred tax assets and liabilities are only offset where there is a legally enforceable right of offset and there is an intention to settle the 
balances net. The deferred tax balances (after offset) for statement of financial position purposes consist solely of deferred tax liabilities 
of £4,297m (2014: £4,082m).

Deferred tax assets in respect of capital losses, trading losses and non-trade deficits have not been recognised as their future recovery 
is uncertain or not currently anticipated. The deferred tax assets not recognised are as follows:

Non-trade deficits

The capital losses and non-trade deficits that arise in the UK are available to carry forward indefinitely. However, the capital losses can 
only be offset against specific types of future capital gains and non-trade deficits against specific future non-trade profits. The trading 
losses arising in the US have up to a 20 year carry forward time limit.

The aggregate amount of temporary differences associated with the unremitted earnings of overseas subsidiaries and joint ventures 
for which deferred tax liabilities have not been recognised at the reporting date is approximately £773m (2014: £2,118m). No liability 
is recognised in respect of the differences because the Company and its subsidiaries are in a position to control the timing of the reversal 
of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. In addition, as a result of 
UK tax legislation, which largely exempts overseas dividends received, the temporary differences are unlikely to lead to additional tax.

Unaudited commentary on tax

Tax strategy
National Grid manages its tax affairs in a proactive and responsible 
way in order to comply with all relevant legislation and minimise 
reputational risk. As a regulated public utility we are very conscious 
of the need to manage our tax affairs responsibly in the eyes of 
our stakeholders. We have a good working relationship with all 
relevant tax authorities and actively engage with them in order to 
ensure that they are fully aware of our view of the tax implications 
of our business initiatives. Management responsibility and 
oversight for our tax strategy, which is approved by the Finance 
Committee, rests with the Finance Director and the Global Tax 
and Treasury Director who monitor our tax activities and report 
to the Finance Committee.

Total UK tax contribution
This is the third year we have disclosed additional information in 
respect of our total UK tax contribution for consistency and to aid 
transparency in an area in which there remains significant public 
interest. As was the case in prior years, the total amount of taxes 
we pay and collect in the UK year on year is significantly more than 
just the corporation tax which we pay on our UK profits. Within the 
total, we again include other taxes paid such as business rates 
and taxes on employment together with employee taxes and other 
indirect taxes.

For 2014/15 our total tax contribution to the UK Exchequer was 
£1.5bn (2013/14: £1.4bn). Taxes borne in 2015 were £761m, a 4% 
increase on taxes borne in 2014 of £733m and primarily due to 
higher corporation tax payments in the current year. Our 2013/14 
total tax contribution of £1.4bn resulted in National Grid being the 
13th highest contributor of UK taxes based on the results of the 
Hundred Group’s 2014 Total Tax Contribution Survey, a position 
commensurate with the size of our business and capitalisation 
relative to other contributors to the Survey. In 2013 we were in 
17th position. In 2014 we ranked 9th in respect of taxes borne.

National Grid’s contribution to the UK economy is again broader 
than just the taxes it pays over to and collects on behalf of HMRC. 
The Hundred Group’s 2014 Total Tax Contribution Survey ranks 
National Grid in 4th place in respect of UK capital expenditure on 
fixed assets. For instance, National Grid’s economic contribution 
also supports a significant number of UK jobs in our supply chain.

The most significant amounts making up the 2014/15 total tax 
contribution were as follows:

Tax transparency
The UK tax charge for the year disclosed in the financial 
statements in accordance with accounting standards and the UK 
corporation tax paid during the year will differ. For transparency 
we have included a reconciliation below of the tax charge per the 
income statement to the UK corporation tax paid in 2014/15.

The tax charge for the Group as reported in the income statement 
is £617m (2013/14: £284m). The UK tax charge is £437m (2013/14: 
£51m) and UK corporation tax paid was £353m (2013/14: £329m), 
with the principal differences between these two measures 
as follows:

Reconciliation of UK total tax charge  
to UK corporation tax paid

Total UK tax charge (current tax £307m 

(2014: £346m) and deferred tax £130m 
(2014: £295m credit))

Tax losses
We have total unrecognised deferred tax assets in respect of losses 
of £255m (2013/14: £280m) of which £250m (2013/14: £274m) are 
capital losses in the UK as set out above. These losses arose as a 
result of the disposal of certain businesses or assets and may be 
available to offset against future capital gains in the UK.

Development of future tax policy
We believe that the continued development of a coherent and 
transparent tax policy in the UK is critical to help drive growth in 
the economy.

We continue to contribute to research into the structure of 
business tax and its economic impact by contributing to the 
funding of the Oxford University Centre for Business Tax at the 
Saïd Business School.

We are a member of a number of industry groups which 
participate in the development of future tax policy, including the 
Hundred Group, which represents the views of Finance Directors 
of FTSE 100 companies and several other large UK companies. 
Our Group Finance Director is Chairman of its Tax Committee. 
This helps to ensure that we are engaged at the earliest opportunity 
on tax issues which affect our business. In the current year we 
have reviewed and responded to a number of HMRC consultations, 
the subject matter of which directly impacts taxes borne or 
collected by our business.

Financial Statements7. Earnings per share (EPS)

EPS is the amount of post-tax profit attributable to each ordinary share. Basic EPS is calculated on profit for the year attributable to 
equity shareholders divided by the weighted average number of shares in issue during the year. Diluted EPS shows what the impact 
would be if all outstanding share options were exercised and treated as ordinary shares at year end. The weighted average number 
of shares is increased by additional shares issued as scrip dividends and reduced by shares repurchased by the Company during 
the year.

Adjusted earnings and EPS, which exclude exceptional items, remeasurements and stranded cost recoveries, are provided to reflect 
the business performance subtotals used by the Company. For further details of exceptional items, remeasurements and stranded 
cost recoveries, see note 4.

8. Dividends

Dividends represent the return of profits to shareholders. Dividends are paid as an amount per ordinary share held. We retain part 
of the profits generated in the year to meet future growth plans and pay out the remainder in accordance with our dividend policy.

Interim dividends are recognised when they become payable to the Company’s shareholders. Final dividends are recognised when they 
are approved by shareholders.

The Directors are proposing a final dividend for the year ended 31 March 2015 of 28.16p per share that will absorb approximately 
£1,054m of shareholders’ equity (assuming all amounts are settled in cash). It will be paid on 5 August 2015 to shareholders who are 
on the register of members at 5 June 2015 and a scrip dividend will be offered as an alternative, subject to shareholders’ approval at 
the Annual General Meeting.

Unaudited commentary on dividends

Following the announcement of our dividend policy in March 
2013, the Board remains confident that National Grid is able 
to support a dividend growing at least in line with RPI inflation 
for the foreseeable future, while continuing to invest as required 
in our regulated assets.

With the exception of the 2013/14 interim dividend paid in January 
2014, a scrip option has been offered for all interim and final 
dividends in the last four years. The scrip take-up as a percentage 
of total shares outstanding (excluding treasury shares) since 
2012/13 was as follows: 2014/15 interim 5%; 2013/14 final 28%; 
2013/14 interim n/a; 2012/13 final 46%; and 2012/13 interim 35%.

In August 2014 we began a share buyback programme that will 
allow us to offer the scrip dividend option for both the full-year and 
interim dividend. The buyback programme is designed to balance 
shareholders’ appetite for the scrip dividend option with our desire 
to operate an efficient balance sheet with appropriate leverage.

Financial Statements9. Goodwill

Goodwill represents the excess of what we paid to acquire businesses over the fair value of their net assets at the acquisition date. 
We assess whether goodwill is recoverable each year by performing an impairment review.

Goodwill is recognised as an asset and is not amortised, but is tested for impairment annually or more frequently if events or changes 
in circumstances indicate a potential impairment. Any impairment is recognised immediately in the income statement and is not 
subsequently reversed.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity 
and translated at the closing exchange rate.

Impairment
Goodwill is allocated to cash-generating units and this allocation is made to those cash-generating units that are expected to benefit from 
the business combination in which the goodwill arose.

Impairments of goodwill are calculated as the difference between the carrying value of the goodwill and the estimated recoverable amount 
of the cash-generating unit to which that goodwill has been allocated. Recoverable amount is defined as the higher of fair value less costs 
to sell and estimated value-in-use at the date the impairment review is undertaken.

Value-in-use represents the present value of expected future cash flows, discounted using a pre-tax discount rate that reflects current 
market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not 
been adjusted.

Impairments are recognised in the income statement and are disclosed separately.

The cost of goodwill at 31 March 2015 was £5,157m (2014: £4,594m) with an accumulated impairment charge of £12m (2014: £nil).

The amounts disclosed above as at 31 March 2015 include balances relating to the following cash-generating units: New York £2,964m 
(2014: £2,640m); Massachusetts £1,108m (2014: £987m); Rhode Island £412m (2014: £367m); and Federal £661m (2014: £600m).

Goodwill is reviewed annually for impairment and the recoverability of goodwill has been assessed by comparing the carrying amount 
of our operations described above (our cash-generating units) with the expected recoverable amount on a value-in-use basis. In each 
assessment, the value-in-use has been calculated based on five year plan projections that incorporate our best estimates of future cash 
flows, customer rates, costs, future prices and growth. Such projections reflect our current regulatory rate plans taking into account 
regulatory arrangements to allow for future rate plan filings and recovery of investment. Our plans have proved to be reliable guides in 
the past and the Directors believe the estimates are appropriate.

The future economic growth rate used to extrapolate projections beyond five years has been maintained at 2.25% (2014: 2.25%). The 
growth rate has been determined having regard to data on projected growth in US real gross domestic product (GDP). Based on our 
business’ place in the underlying US economy, it is appropriate for the terminal growth rate to be based upon the overall growth in real 
GDP and, given the nature of our operations, to extend over a long period of time. Cash flow projections have been discounted to reflect 
the time value of money, using a pre-tax discount rate of 9% (2014: 9%). The discount rate represents the estimated weighted average 
cost of capital of these operations.

While it is possible that a key assumption in the calculation could change, the Directors believe that no reasonably foreseeable change 
would result in an impairment of goodwill, in view of the long-term nature of the key assumptions and the margin by which the estimated 
fair value exceeds the carrying amount.

As part of their review, the Directors specifically reviewed the carrying value of goodwill associated with Clean Line Energy Partners LLC. 
This review resulted in a full impairment being recorded of £12m.

10. Other intangible assets

Other intangible assets include software and acquisition-related assets (such as brand names and customer relationships), which are 
written down (amortised) over the length of period we expect to receive a benefit from the asset.

Identifiable intangible assets are recorded at cost less accumulated amortisation and any provision for impairment. Other intangible assets 
are tested for impairment only if there is an indication that the carrying value of the assets may have been impaired. Impairments of assets 
are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does 
not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which that asset 
belongs is estimated. Impairments are recognised in the income statement and are disclosed separately. Any assets which suffered 
impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date.

Internally generated intangible assets, such as software, are recognised only if: an asset is created that can be identified; it is probable that 
the asset created will generate future economic benefits; and the development cost of the asset can be measured reliably. Where no internally 
generated intangible asset can be recognised, development expenditure is recorded as an expense in the period in which it is incurred.

On a business combination, as well as recording separable intangible assets possessed by the acquired entity at their fair value, identifiable 
intangible assets that arise from contractual or other legal rights are also included in the statement of financial position at their fair value. 
Acquisition-related intangible assets principally comprise customer relationships.

Other intangible assets are amortised on a straight-line basis over their estimated useful economic lives. Amortisation periods for categories 
of intangible assets are:

Financial Statements11. Property, plant and equipment

The following note shows the physical assets controlled by us. The cost of these assets primarily represents the amount initially paid 
for them. A depreciation expense is charged to the income statement to reflect annual wear and tear and the reduced value of the 
asset over time. Depreciation is calculated by estimating the number of years we expect the asset to be used (useful economic life) 
and charging the cost of the asset to the income statement equally over this period.

Our strategy in action
We operate an energy networks business and therefore have a significant physical asset base. We continue to invest in our networks 
to maintain reliability, create new customer connections and ensure our networks are flexible and resilient. Our business plan envisages 
these additional investments will be funded through a mixture of cash generated from operations and the issue of new debt.

Property, plant and equipment is recorded at cost, less accumulated depreciation and any impairment losses.

Cost includes the purchase price of the asset, any payroll and finance costs incurred which are directly attributable to the construction 
of property, plant and equipment as well as the cost of any associated asset retirement obligations.

Property, plant and equipment includes assets in which the Company’s interest comprises legally protected statutory or contractual rights 
of use. Additions represent the purchase or construction of new assets, including capital expenditure for safety and environmental assets, 
and extensions to, enhancements to, or replacement of existing assets.

Contributions received prior to 1 July 2009 towards the cost of property, plant and equipment are included in trade and other payables 
as deferred income and credited on a straight-line basis to the income statement over the estimated useful economic lives of the assets 
to which they relate.

Contributions received post 1 July 2009 are recognised in revenue immediately, except where the contributions are consideration for 
a future service, in which case they are recognised initially as deferred income and revenue is subsequently recognised over the period 
in which the service is provided.

No depreciation is provided on freehold land or assets in the course of construction.

Other items of property, plant and equipment are depreciated, on a straight-line basis, at rates estimated to write off their book values 
over their estimated useful economic lives. In assessing estimated useful economic lives, consideration is given to any contractual 
arrangements and operational requirements relating to particular assets. The assessments of estimated useful economic lives and 
residual values of assets are performed annually. Unless otherwise determined by operational requirements, the depreciation periods 
for the principal categories of property, plant and equipment are, in general, as shown in the table below:

Freehold and leasehold buildings 
Plant and machinery:

Electricity transmission plant 
Electricity distribution plant 
Electricity generation plant 
Interconnector plant 
Gas plant – mains, services and regulating equipment 
Gas plant – storage 
Gas plant – meters

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised within operating 
profit in the income statement.

Items within property, plant and equipment are tested for impairment only if there is some indication that the carrying value of the assets 
may have been impaired.

Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. 
Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-
generating unit to which that asset belongs is estimated.

Material impairments are recognised in the income statement and are disclosed separately.

Any assets which suffered impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date.

Financial Statements13. Financial and other investments

Financial and other investments include two main categories. Assets classified as available-for-sale typically represent investments 
in short-term money funds and quoted investments in equities or bonds of other companies. The second category is loans and 
receivables which includes bank deposits with a maturity of greater than three months, and cash balances that cannot be readily used 
in operations, principally collateral pledged for certain borrowings.

Financial assets, liabilities and equity instruments are classified according to the substance of the contractual arrangements entered 
into, and recognised on trade date. Available-for-sale financial assets are non-derivatives that are either designated in this category or 
not classified in any other categories.

Available-for-sale financial investments are recognised at fair value plus directly related incremental transaction costs, and are subsequently 
carried at fair value in the statement of financial position. Changes in the fair value of available-for-sale investments are recognised directly 
in other comprehensive income, until the investment is disposed of or is determined to be impaired. At this time the cumulative gain or loss 
previously recognised in equity is included in the income statement for the period. Investment income is recognised using the effective 
interest method and taken through interest income in the income statement.

Loans receivable and other receivables are initially recognised at fair value and subsequently held at amortised cost using the effective 
interest method. Interest income, together with gains and losses when the loans and receivables are derecognised or impaired, are 
recognised in the income statement.

Subsequent to initial recognition, the fair values of financial assets measured at fair value that are quoted in active markets are based on 
bid prices. When independent prices are not available, fair values are determined by using valuation techniques that are consistent with 
techniques commonly used by the relevant market. The techniques use observable market data.

14. Investments in joint ventures and associates

Investments in joint ventures and associates represent businesses we do not control, but instead exercise joint control or significant 
influence.

A joint venture is an arrangement established to engage in economic activity, which the Company jointly controls with other parties and 
has rights to the net assets of the arrangement. An associate is an entity which is neither a subsidiary nor a joint venture, but over which 
the Company has significant influence.

The joint ventures and associates have no significant contingent liabilities to which the Group is exposed, and the Group has no significant 
contingent liabilities in relation to its interest in the joint ventures and associates.

Outstanding balances with joint ventures and associates are shown in note 28.

15. Derivative financial instruments

Derivatives are financial instruments that derive their value from the price of an underlying item such as interest rates, foreign exchange 
rates, credit spreads, commodities, equity or other indices. In accordance with Board approved policies, derivatives are transacted 
to manage our exposure to fluctuations in interest rate and foreign exchange rate on borrowings and other contractual cash flows. 
Specifically, we use derivatives to manage these risks from our financing portfolio to optimise the overall cost of accessing the debt 
capital markets. These derivatives are analysed below. We also use derivatives to manage our operational market risks from 
commodities. The commodity derivative contracts are detailed in note 30(e).

Derivative financial instruments are initially recognised at fair value and subsequently remeasured at fair value at each reporting date. 
Changes in fair values are recorded in the period they arise, in either the income statement or other comprehensive income depending on 
the applicable accounting standards. Where the fair value of a derivative is positive it is carried as a derivative asset, and where negative 
as a derivative liability. 

We calculate fair value of the financial derivatives by discounting all future cash flows using the market yield curve at the reporting date. 
The market yield curve for each currency is obtained from external sources for interest and foreign exchange rates. In the absence of 
sufficient market data, fair values would be based on the quoted market price of similar derivatives. Analysis of these derivatives and the 
various methods used to calculate their respective fair values is detailed below and in note 30.

1.  The notional contract amounts of derivatives indicate the gross nominal value of transactions outstanding at the reporting date.

Where possible, derivatives held as hedging instruments are formally designated as hedges as defined in IAS 39. Derivatives may qualify 
as hedges for accounting purposes if they are fair value hedges, cash flow hedges or net investment hedges. Our use of derivatives may 
entail a derivative transaction qualifying for one or more hedge type designations under IAS 39.

Hedge accounting allows derivatives to be designated as a hedge of another non-derivative financial instrument, to mitigate the impact 
of potential volatility in the income statement of changes in the fair value of the derivative instruments. To qualify for hedge accounting, 
documentation is prepared specifying the hedging strategy, the component transactions and methodology used for effectiveness 
measurement. National Grid uses three hedge accounting methods, which are described as follows:

Fair value hedges
Fair value hedges principally consist of interest rate and cross-currency swaps that are used to protect against changes in the fair value 
of fixed-rate, long-term financial instruments due to movements in market interest rates. For qualifying fair value hedges, all changes in 
the fair value of the derivative and changes in the fair value of the item in relation to the risk being hedged are recognised in the income 
statement to the extent the fair value hedge is effective. Adjustments made to the carrying amount of the hedged item for fair value 
hedges will be amortised over the remaining life, in line with the hedged item. 

Cross-currency interest rate/interest rate swaps

367

Cash flow hedges
Exposure arises from the variability in future interest and currency cash flows on assets and liabilities which bear interest at variable rates 
or are in a foreign currency. Interest rate and cross-currency swaps are maintained, and designated as cash flow hedges, where they 
qualify, to manage this exposure. Fair value changes on designated cash flow hedges are initially recognised directly in the cash flow 
hedge reserve, as gains or losses recognised in equity and any ineffective portion is recognised immediately in the income statement. 
Amounts are transferred from equity and recognised in the income statement as the income or expense is recognised on the hedged item.

Forward foreign currency contracts are used to hedge anticipated and committed future currency cash flows. Where these contracts 
qualify for hedge accounting they are designated as cash flow hedges. On recognition of the underlying transaction in the financial 
statements, the associated hedge gains and losses, deferred in equity, are transferred and included with the recognition of the 
underlying transaction.

15. Derivative financial instruments continued

Cash flow hedges continued
When a forecast transaction is no longer expected to occur, the cumulative gain or loss previously reported in equity is transferred to the 
income statement.

Where a non-financial asset or a non-financial liability results from a forecast transaction or firm commitment being hedged, the amounts 
deferred in equity are included in the initial measurement of that non-monetary asset or liability.

Net investment hedges
Borrowings, cross-currency swaps and forward currency contracts are used in the management of the foreign exchange exposure arising 
from the investment in non-sterling denominated subsidiaries. Where these contracts qualify for hedge accounting they are designated as 
net investment hedges.

The cross-currency swaps and forward foreign currency contracts are hedge accounted using the spot to spot method. The foreign 
exchange gain or loss on retranslation of the borrowings and the spot to spot movements on the cross-currency swaps and forward 
currency contracts are transferred to equity to offset gains or losses on translation of the net investment in the non-sterling denominated 
subsidiaries, with any ineffective portion recognised immediately in the income statement.

Derivatives not in a formal hedge relationship
Our policy is not to use derivatives for trading purposes. However, due to the complex nature of hedge accounting under IAS 39 some 
derivatives may not qualify for hedge accounting, or are specifically not designated as a hedge where natural offset is more appropriate. 
Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised in remeasurements within 
the income statement.

Discontinuation of hedge accounting
Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated, exercised or no longer qualifies for hedge 
accounting. At that time, any cumulative gains or losses relating to cash flow hedges recognised in equity are initially retained in equity 
and subsequently recognised in the income statement in the same periods in which the previously hedged item affects profit or loss. 
Amounts deferred in equity with respect to net investment hedges are subsequently recognised in the income statement in the event of 
the disposal of the overseas operations concerned. For fair value hedges, the cumulative adjustment recorded to the carrying value of the 
hedged item at the date hedge accounting is discontinued is amortised to the income statement using the effective interest method.

Embedded derivatives
No adjustment is made with respect to derivative clauses embedded in financial instruments or other contracts that are defined as closely 
related to those instruments or contracts. Consequently these embedded derivatives are not accounted for separately from the debt 
instrument. Where there are embedded derivatives in host contracts not closely related, the embedded derivative is separately accounted 
for as a derivative financial instrument.

Financial Statements16. Inventories and current intangible assets

Inventories represent assets that we intend to use in order to generate revenue in the short term, either by selling the asset itself 
(for example fuel stocks) or by using it to fulfil a service to a customer or to maintain our network (consumables).

Inventories are stated at the lower of weighted average cost and net realisable value.

Where applicable, cost comprises direct materials and direct labour costs as well as those overheads that have been incurred in bringing 
the inventories to their present location and condition.

Emission allowances, principally relating to the emissions of carbon dioxide in the UK and sulphur and nitrous oxides in the US, are 
recorded as intangible assets within current assets and are initially recorded at cost and subsequently at the lower of cost and net realisable 
value. Where emission allowances are granted by relevant authorities, cost is deemed to be equal to the fair value at the date of allocation. 
Receipts of such grants are treated as deferred income, which is recognised in the income statement as the related charges for emissions 
are recognised or on impairment of the related intangible asset. A provision is recorded in respect of the obligation to deliver emission 
allowances and emission charges are recognised in the income statement in the period in which emissions are made.

Current intangible assets – emission allowances

There is a provision for obsolescence of £28m against inventories as at 31 March 2015 (2014: £29m).

17. Trade and other receivables

Trade and other receivables are amounts which are due from our customers for services (and commodities in the US) we have 
provided. Other receivables also include prepayments made by us, for example, property lease rentals paid in advance.

Trade and other receivables are initially recognised at fair value and subsequently measured at amortised cost, less any appropriate 
allowances for estimated irrecoverable amounts. A provision is established for irrecoverable amounts when there is objective evidence 
that amounts due under the original payment terms will not be collected.

Financial Statements18. Cash and cash equivalents

Cash and cash equivalents include cash balances, together with short-term investments with an original maturity of less than three 
months that are readily convertible to cash.

Net cash and cash equivalents reflected in the cash flow statement are net of bank overdrafts, which are reported in borrowings. The carrying 
amounts of cash and cash equivalents and bank overdrafts approximate their fair values.

Cash at bank earns interest at floating rates based on daily bank deposit rates. Short-term deposits are made for periods varying between 
one day and three months, depending on the immediate cash requirements, and earn interest at the respective short-term deposit rates.

Net cash and cash equivalents held in currencies other than sterling have been converted into sterling at year-end exchange rates. For further 
information on currency exposures, refer to note 30(d).

19. Borrowings

We borrow money primarily in the form of bonds and bank loans. These are for a fixed term and may have fixed or floating interest rates 
or are linked to RPI. As indicated in note 15, we use derivatives to manage risks associated with interest rates and foreign exchange.

Our strategy in action
Our price controls and rate plans require us to fund our networks within a certain ratio of debt to equity and, as a result, we have issued 
a significant amount of debt. As we continue to invest in our networks, the value of debt is expected to increase over time. To maintain 
a strong balance sheet and to allow us to access capital markets at commercially acceptable interest rates, we balance the amount of 
debt we issue with the value of our assets, and take account of certain other metrics used by credit rating agencies.

Borrowings, which include interest-bearing and inflation linked debt and overdrafts, are recorded at their initial fair value which normally 
reflects the proceeds received, net of direct issue costs less any repayments. Subsequently these are stated at amortised cost, using the 
effective interest method. Any difference between the proceeds after direct issue costs and the redemption value is recognised over the 
term of the borrowing in the income statement using the effective interest method.

The fair value of borrowings at 31 March 2015 was £30,103m (2014: £28,131m). Where market values were available, fair value of 
borrowings (Level 1) was £14,583m (2014: £17,388m). Where market values were not available, fair value of borrowings (Level 2) was 
£15,520m (2014: £10,743m), calculated by discounting cash flows at prevailing interest rates. The notional amount outstanding of the 
debt portfolio at 31 March 2015 was £25,419m (2014: £25,539m).

The assets of the Colonial Gas Company and the Niagara Mohawk Power Corporation and certain gas distribution assets of the 
Narragansett Electric Company are subject to liens and other charges and are provided as collateral over borrowings totalling £424m 
at 31 March 2015 (2014: £438m).

Collateral is placed with or received from any counterparty where we have entered into a credit support annex to the ISDA Master Agreement 
once the current mark-to-market valuation of the trades between the parties exceeds an agreed threshold. Included in current bank loans 
is £540m (2014: £843m) in respect of cash received under collateral agreements. For further details of our borrowing facilities, refer to 
note 31. For further details of our bonds in issue, please refer to the debt investor section of our website.

Assets held under finance leases are recognised at their fair value or, if lower, the present value of the minimum lease payments on 
inception. The corresponding liability is recognised as a finance lease obligation within borrowings. Rental payments are apportioned 
between finance costs and reduction in the finance lease obligation, so as to achieve a constant rate of interest.

Assets held under finance leases are depreciated over the shorter of their useful life and the lease term.

Finance lease obligations

Gross finance lease liabilities are repayable as follows:

Less than 1 year

As at 31 March 2015, total borrowings of £25,910m (2014: £25,950m) including bonds, bank loans, commercial paper, collateral, finance 
leases and other debt had decreased by £40m. This represents the ongoing refinancing of the debt portfolio. We expect to repay £3,028m 
of our total borrowings in the next 12 months including commercial paper, collateral and interest, and to fund this repayment through the 
capital and money markets. The average long-term debt maturity of the portfolio is 13 years (2014: 12 years).

22. Pensions and other post-retirement benefits

Substantially all our employees are members of either DB (defined benefit) or DC (defined contribution) pension plans. The principal 
UK plans are the National Grid UK Pension Scheme, the National Grid Electricity Group of the Electricity Supply Pension Scheme and 
The National Grid YouPlan. In the US, we have a number of plans and also provide healthcare and life insurance benefits to eligible 
retired US employees.

The fair value of associated plan assets and present value of DB obligations are updated annually. For further details and the actuarial 
assumptions used to value the obligations, see note 29.

We separately present our UK and US pension plans to show geographical split. Below we provide a more detailed analysis of the 
amounts recorded in the primary financial statements.

For DC plans, the Group pays contributions into separate funds on behalf of the employee and has no further obligations to employees. 
The risks associated with this type of plan are assumed by the member. 

For DB retirement plans, members receive benefits on retirement, the value of which is dependent on factors such as salary and length of 
pensionable service. The Group underwrites both financial and demographic risks associated with this type of plan. 

The cost of providing benefits in a DB plan is determined using the projected unit method, with actuarial valuations being carried out at 
each reporting date by a qualified actuary. This valuation method is an accrued benefits valuation method that makes allowance for 
projected earnings.

126

Financial Statements22. Pensions and other post-retirement benefits continued

The Group’s obligation in respect of DB pension plans is calculated separately for each plan by projecting the estimated amount of future 
benefit payments that employees have earned for their pensionable service in the current and prior periods. These future benefit payments 
are discounted to determine the present value of the liabilities and the fair value of plan assets and any unrecognised past service cost is 
then deducted. The discount rate used is the yield at the valuation date on high-quality corporate bonds.

The Group takes advice from independent actuaries relating to the appropriateness of any key assumptions applied which include life 
expectancy of members, expected salary and pension increases, and inflation. It should be noted that comparatively small changes in 
the assumptions used may have a significant effect on the amounts recognised in the income statement and the statement of other 
comprehensive income and the net liability recognised in the statement of financial position.

Remeasurements of net retirement obligations are recognised in full in the period in which they occur in the statement of other 
comprehensive income.

Risks
The DB pension obligations and other post-retirement benefit liabilities are exposed to the primary risks outlined below.

Liabilities are calculated using discount rates set with reference to yields on high-quality corporate bonds prevailing in the US and UK 
debt markets and will fluctuate as yields change. Plan funds are invested in a variety of asset classes, principally: equities, government 
securities, corporate bonds and property. Consequently, actual returns will differ from the underlying discount rate adopted and therefore 
have an impact on the net balance sheet liability.

Changes in inflation will affect both current and future pension payments and are partially mitigated through investment in inflation 
matching assets and hedging instruments.

Longevity is also a key driver of liabilities and changes in expected mortality will have a direct impact on liabilities. The liabilities are, 
in aggregate, relatively mature which serves to mitigate this risk to some extent.

Each plan’s investment strategy seeks to balance the level of investment return sought with the aim of reducing volatility and risk. 
In undertaking this approach reference is made both to the maturity of the liabilities and the funding level of that plan. A number 
of further strategies are employed to manage underlying risks, including liability matching asset strategies, diversification of asset 
portfolios, interest rate hedging and active management of foreign exchange exposure.

– analysis of items in the primary statements continued

23. Provisions

We make provisions when an obligation exists, resulting from a past event and it is probable that cash will be paid to settle it, but the 
exact amount of cash required can only be estimated.

The main estimates relate to environmental remediation and decommissioning costs for various sites we own or have owned and other 
provisions, including restructuring plans and lease contracts we have entered into that are now loss making.

Our strategy in action
We are committed to the protection and enhancement of the environment. However, we have acquired, owned and operated a number 
of businesses which have, during the course of their operations, created an environmental impact. Therefore we have a provision that 
reflects the expected cost to remediate these sites. Current operations will seldom result in new sites with significant expected costs 
being added to the provision.

Provisions are recognised where a legal or constructive obligation exists at the reporting date, as a result of a past event, where the 
amount of the obligation can be reliably estimated and where the outflow of economic benefit is probable.

Provision is made for decommissioning and environmental costs, based on future estimated expenditures, discounted to present values. 
An initial estimate of decommissioning and environmental costs attributable to property, plant and equipment is recorded as part of the 
original cost of the related property, plant and equipment.

Changes in the provision arising from revised estimates or discount rates or changes in the expected timing of expenditures that relate 
to property, plant and equipment are recorded as adjustments to their carrying value and depreciated prospectively over their remaining 
estimated useful economic lives; otherwise such changes are recognised in the income statement.

The unwinding of the discount is included within the income statement as a financing charge.

Environmental provision
The environmental provision represents the estimated restoration and remediation costs relating to a number of sites owned and 
managed by subsidiary undertakings, together with certain US sites that National Grid no longer owns. The environmental provision

The remediation expenditure in the UK relates to old gas manufacturing sites and also to electricity transmission sites. Cash flows are 
expected to be incurred between 2015 and 2060. A number of estimation uncertainties affect the calculation of the provision, including the 
impact of regulation, accuracy of the site surveys, unexpected contaminants, transportation costs, the impact of alternative technologies 
and changes in the discount rate. This provision incorporates our best estimate of the financial effect of these uncertainties, but future 
changes in any of the assumptions could materially impact the calculation of the provision. The undiscounted amount is the undiscounted 
best estimate of the liability having regard to these uncertainties.

The remediation expenditure in the US is expected to be incurred between 2015 and 2071. The uncertainties regarding the calculation 
of this provision are similar to those considered in respect of UK sites. This expenditure is expected to be largely recoverable from 
ratepayers under the terms of various rate agreements in the US.

Decommissioning provision
The decommissioning provision represents £51m (2014: £55m) of expenditure relating to asset retirement obligations expected to be 
incurred until 2075, and £64m (2014: £72m) of expenditure relating to the demolition of gas holders expected to be incurred until 2022. 
It also includes the net present value of the estimated expenditure (discounted at a real rate of 2%) expected to be incurred until 2033 
in respect of the decommissioning of certain US nuclear generating units that National Grid no longer owns.

Restructuring provision
The restructuring provision principally relates to business reorganisation costs in the UK and is expected to be incurred until 2023.

Emissions provision 
The provision for emission costs is expected to be settled using emission allowances granted.

Other provisions
Included within other provisions at 31 March 2015 are amounts provided in respect of onerous lease commitments and rates payable 
on surplus properties of £117m (2014: £117m) with expenditure expected to be incurred until 2039.

Other provisions also include £182m (2014: £160m) of estimated liabilities in respect of past events insured by insurance subsidiary 
undertakings, including employer liability claims. In accordance with insurance industry practice, these estimates are based on experience 
from previous years and there is, therefore, no identifiable payment date. It also includes £13m (2014: £13m) in respect of obligations 
associated with investments in joint ventures.

24. Share capital

Ordinary share capital represents the total number of shares issued which are publicly traded. We also disclose the number of treasury 
shares the Company holds, which are shares that the Company has bought itself, predominantly to satisfy employee share option 
plan liabilities.

Share capital is accounted for as an equity instrument. An equity instrument is any contract that includes a residual interest in the 
consolidated assets of the Company after deducting all its liabilities and is recorded at the proceeds received, net of direct issue costs, 
with an amount equal to the nominal amount of the shares issued included in the share capital account and the balance recorded in 
the share premium account.

1.   The issue of shares under the scrip dividend programme is considered to be a bonus issue under the terms of the Companies Act 2006 and the nominal value of the shares is charged 

to the share premium account.

The share capital of the Company consists of ordinary shares of 1117⁄43 pence nominal value each including ADSs. The ordinary shares 
and ADSs allow holders to receive dividends and vote at general meetings of the Company. The Company holds treasury shares but may 
not exercise any rights over these shares including the entitlement to vote or receive dividends. There are no restrictions on the transfer 
or sale of ordinary shares.

In line with the provisions of the Companies Act 2006, the Company has amended its Articles of Association and ceased to have 
authorised share capital.

Treasury shares
At 31 March 2015, the Company held 153m (2014: 124m) of its own shares. The market value of these shares as at 31 March 2015 
was £1,323m (2014: £1,019m).

The Company made the following transactions in respect of its own shares during the year ended 31 March 2015:

1.  During the year, the Company, as part of management of the dilutive effect of share issuances under the scrip dividend programme, 
repurchased 37m ordinary shares for aggregate consideration of £338m, including transaction costs. The shares repurchased have 
a nominal value of £4m and represented approximately 1% of the ordinary shares in issue as at 31 March 2015.

2. During the year, 3m (2014: 2m) treasury shares were gifted to National Grid Employee Share Trusts and 5m (2014: 3m) treasury 

shares were re-issued in relation to employee share schemes, in total representing approximately 0.2% (2014: 0.1%) of the ordinary 
shares in issue as at 31 March 2015. The nominal value of these shares was £1m (2014: £1m) and the total proceeds received were 
£23m (2014: £14m).

3. During the year, the Company made payments totalling £7m (2014: £3m) to National Grid Employee Share Trusts, outside of its share 
repurchase programme, to enable the trustees to make purchases of National Grid plc shares in order to satisfy the requirements 
of employee share option and reward plans.

The maximum number of shares held during the year was 153m ordinary shares (2014: 129m) representing approximately 3.9% (2014: 3.4%) 
of the ordinary shares in issue as at 31 March 2015 and having a nominal value of £17m (2014: £15m).

Financial Statements25. Other equity reserves

Other equity reserves are different categories of equity as required by accounting standards and represent the impact of a number 
of our historical transactions.

Other equity reserves comprise the translation reserve (see accounting policy B in note 1), cash flow hedge reserve (see note 15), 
available-for-sale reserve (see note 13), the capital redemption reserve and the merger reserve. The merger reserve arose as a result of 
the application of merger accounting principles under the then prevailing UK GAAP, which under IFRS 1 was retained for mergers that 
occurred prior to the IFRS transition date. Under merger accounting principles, the difference between the carrying amount of the capital 
structure of the acquiring vehicle and that of the acquired business was treated as a merger difference and included within reserves.

As the amounts included in other equity reserves are not attributable to any of the other classes of equity presented, they have been 
disclosed as a separate classification of equity.

The merger reserve represents the difference between the carrying value of subsidiary undertaking investments and their respective 
capital structures following the Lattice demerger from BG Group plc and the 1999 Lattice refinancing.

The cash flow hedge reserve on interest rate swap contracts will be continuously transferred to the income statement until the borrowings 
are repaid. The amount due to be released from reserves to the income statement next year is £15m (pre-tax) and the remainder released 
with the same maturity profile as borrowings due after more than one year.

26. Net debt

Net debt represents the amount of borrowings and overdrafts less cash, financial investments and related derivatives.

Funding and liquidity risk management is carried out by the treasury function under policies and guidelines approved by the Finance 
Committee of the Board. The Finance Committee is responsible for the regular review and monitoring of treasury activity and for the 
approval of specific transactions, the authority for which fall outside the delegation of authority to management.

The primary objective of the treasury function is to manage our funding and liquidity requirements. A secondary objective is to manage 
the associated financial risks, in the form of interest rate risk and foreign exchange risk, to within pre-authorised parameters. Details of the 
main risks arising from our financing and commodity hedging activities can be found in the risk factors discussion starting on page 173 
and in note 30 to the consolidated financial statements on pages 141 to 148.

Investment of surplus funds, usually in short-term fixed deposits or placements with money market funds that invest in highly liquid 
instruments of high credit quality, is subject to our counterparty risk management policy.

The movement in cash and cash equivalents is reconciled to movements in net debt.

Financial StatementsNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Notes to the consolidated financial statements
– supplementary information

This section includes information that is important to enable a full understanding of our financial position, particularly areas 
of potential risk that could affect us in the future.

We also include specific disclosures for British Transco Finance Inc., Niagara Mohawk Power Corporation and National Grid 
Gas plc in accordance with various rules including Rule 3-10 of Regulation S-X (a US SEC requirement), as they have issued 
public debt securities which have been guaranteed by National Grid plc and one of its subsidiary companies, National Grid 
Gas plc. Additional disclosures have also been included in respect of the two guarantor companies. These disclosures are 
in lieu of publishing separate financial statements for these companies. See note 34 for further information.

27. Commitments and contingencies

Commitments are those amounts that we are contractually required to pay in the future as long as the other party meets its obligations. 
These commitments primarily relate to operating lease rentals, energy purchase agreements and contracts for the repurchase of 
network assets which, in many cases, extend over a long period of time. We also disclose any contingencies, which include guarantees 
that companies have given, where we pledge assets against current obligations that will remain for a specific period.

1.   Energy purchase commitments relate to contractual commitments to purchase electricity or gas that are used to satisfy physical delivery requirements to our customers or for energy that 

we use ourselves (i.e. normal purchase, sale or usage) and hence are accounted for as ordinary purchase contracts. Details of commodity contracts that do not meet the normal purchase, 
sale or usage criteria, and hence are accounted for as derivative contracts, are shown in note 30(e).

The total of future minimum sublease payments expected to be received under non-cancellable subleases is £26m (2014: £21m).

Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate 
resolution of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position.

audited section of the Remuneration Report and note 3(c).

29. Actuarial information on pensions and other post-retirement benefits

Further details of the DB plans terms and the actuarial assumptions used to value the obligations are set out in this note. 

When deciding on these assumptions we take independent actuarial advice. Comparatively small changes in the assumptions applied 
may have a significant effect on the overall deficit or surplus of a DB plan.

UK pension plans
National Grid’s defined benefit pension arrangements are funded with assets held in separate trustee administered funds. The arrangements 
are managed by trustee companies with boards consisting of company and member appointed directors. The directors are required to 
manage the arrangements in accordance with local regulations and the arrangements’ governing documents, acting on behalf of their 
beneficiaries.

The arrangements are subject to independent actuarial funding valuations at least every three years and following consultation and 
agreement with us, the qualified actuary certifies the employers’ contribution, which, together with the specified contributions payable 
by the employees and proceeds from the plans’ assets, are expected to be sufficient to fund the benefits payable. The last full actuarial 
valuations were carried out as at 31 March 2013. The next valuations are required to be carried out as at 31 March 2016. 

The results of the 2013 valuations are shown below:

From April 2014 an annual cap was placed on future increases to the salary used to calculate pensions at the lower of 3% or the annual 
increase in RPI. This capped salary applied to all pensionable service from 1 April 2013 onwards. During the year ended 31 March 2014 
these changes resulted in a past service credit of £11m to the income statement (see note 22) and a change to the salary increase 
assumption which affects how our DB liabilities as at 31 March have been calculated. These changes are to ensure our schemes remain 
affordable and sustainable over the coming years.

29. Actuarial information on pensions and other post-retirement benefits continued

National Grid UK Pension Scheme
The 2013 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future 
benefit accrual was 36% of pensionable earnings (currently 33% by employers and 3% by employees). In addition, National Grid makes 
payments to the scheme to cover administration costs and the Pension Protection Fund levy.

Following the 2013 valuation, National Grid and the Trustees agreed a recovery plan which would see the funding deficit repaid by 
31 March 2027. Under the schedule of contributions, payments of £60m were made in 2013/14 and £99m in 2014/15 and will thereafter 
rise in line with RPI until 2026/27. As part of the 2013 agreement, National Grid has established a security arrangement with a charge in 
favour of the Trustees. At 31 March 2015 the value of this was required to be £397m. This was provided via £300m in letters of credit and 
approximately £198m in UK Government bonds and cash. The assets held as security will be paid to the scheme in the event that National 
Grid Gas plc (NGG) is subject to an insolvency event, is given notice of less than 12 months that Ofgem intends to revoke its licence under 
the Gas Act 1986, or National Grid fails to make the required contributions in relation to the scheme. The assets held as security will be 
released back to National Grid if the scheme moves into surplus. In addition, National Grid will make a payment of £200m (increased in 
line with RPI) into the scheme if NGG’s credit rating by two out of three specified agencies falls below certain agreed levels for a period 
of 40 days. 

This scheme ceased to allow new hires to join from 1 April 2002. A DC section of the scheme was offered for employees joining after this 
date, which has since been replaced by The National Grid YouPlan (see below).

National Grid Electricity Group of the Electricity Supply Pension Scheme
The 2013 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future 
benefit accrual was 33.4% of pensionable earnings (currently 27.5% by employers and an average of 5.9% by employees). 

Following the 2013 valuation, National Grid and the Trustees agreed a recovery plan that would see the funding deficit repaid by 31 March 
2027. Under the schedule of contributions, a payment of £80m was made in 2013/14 and £46m in 2014/15. Thereafter annual payments 
are due of £47m in 2015/16 rising in line with RPI until 2026/27. As part of the 2013 agreement, National Grid has established security 
arrangements with a charge in favour of the Trustees. At 31 March 2015 the value of this was required to be £150m. This was provided via 
£150m in a letter of credit. In addition, approximately £36m in UK Government bonds and cash was held. The assets held as security will 
be paid to the scheme in the event that National Grid Electricity Transmission plc (NGET) is subject to an insolvency event, or ceases to 
hold a licence granted under the Electricity Act 1989. The assets held as security will be released back to National Grid if the scheme 
moves into surplus. National Grid has also agreed to make a payment in respect of the deficit up to a maximum of £500m should certain 
triggers be breached; namely if NGET ceases to hold the licence granted under the Electricity Act 1989 or NGET’s credit rating by two out 
of three specified agencies falls below certain agreed levels for a period of 40 days. 

The scheme closed to new members from 1 April 2006.

The National Grid YouPlan
The National Grid YouPlan (YouPlan) is a DC scheme that was launched in 2013 and under the rules of the plan, National Grid double 
matches contributions to YouPlan up to a maximum of 6% of employee salary. YouPlan is the qualifying scheme used for automatic 
enrolment and new hires are enrolled into YouPlan.

US pension plans
National Grid sponsors numerous non-contributory DB pension plans. The DB plans provide retirement benefits to vested union employees, 
as well as vested non-union employees hired before 1 January 2011. Benefits under these plans generally reflect age, years of service and 
compensation and are paid in the form of an annuity or lump sum. An independent actuary performs valuations annually. The Company 
funds the defined benefit plans by contributing no less than the minimum amount required, but no more than the maximum tax deductible 
amount allowed under US Internal Revenue Service regulations. The range of contributions based upon these regulations can vary 
significantly based upon the funded status of the plans. At present, there is some flexibility in the amount that is contributed on an annual 
basis. In general, the Company’s policy for funding the US pension plans is to contribute the amounts collected in rates and capitalised in 
the rate base during the year, to the extent that the funding is no less than the minimum amount required. The assets of the plans are held 
in trusts and administered by fiduciary committees comprised of appointed employees of the Company.

National Grid also has several DC pension plans, primarily comprised of employee savings and Company matching contributions. 
Non-union employees hired after 1 January 2011 as well as new hires in 10 groups of represented union employees, receive a core 
contribution into the DC plan, irrespective of the employee’s contribution into the plan.

US retiree healthcare and life insurance plans
National Grid provides healthcare and life insurance benefits to eligible retired US employees. Eligibility is based on certain age and length 
of service requirements and in most cases retirees contribute to the cost of their healthcare coverage. In the US, there is no governmental 
requirement to pre-fund post-retirement health and welfare plans. However, in general, the Company’s policy for funding the US retiree 
healthcare and life insurance plans is to contribute amounts collected in rates and capitalised in the rate base during the year.

1.   The discount rates for pension liabilities have been determined by reference to appropriate yields on high-quality corporate bonds prevailing in the UK and US debt markets at the 

reporting date.

2.  A promotional scale has also been used where appropriate. The UK assumption stated is that relating to service prior to 1 April 2014. The UK assumption for the rate of increase in salaries 

for service after this date is 2.1%.

3.  This is the key assumption that determines assumed increases in pensions in payment and deferment in the UK only. The assumptions for the UK were 2.9% (2014: 3.3%; 2013: 3.4%) for 

increases in pensions in payment and 2.1% (2014: 3.3%; 2013: 3.4%) for increases in pensions in deferment.

For sensitivity analysis see note 33.

Financial Statements30. Financial risk management

Our activities expose us to a variety of financial risks including currency risk, interest rate risk, commodity price risk, credit risk, capital 
risk and liquidity risk. Our risk management programme focuses on the unpredictability of financial markets and seeks to minimise 
potential volatility of financial performance from these risks. We use financial instruments, including derivative financial instruments, 
to manage risks of this type.

This note describes our approach to managing risk, including an analysis of assets and liabilities by currency type and an analysis 
of interest rate category for our net debt. We are required by accounting standards to also include a number of specific disclosures 
(such as a maturity analysis of contractual undiscounted cash flows) and have included these requirements below.

Risk management related to financing activities is carried out by a central treasury department under policies approved by the Finance 
Committee of the Board. The objective of the treasury department is to manage funding and liquidity requirements, including managing 
associated financial risks, to within acceptable boundaries. The Finance Committee provides written principles for overall risk management, 
as well as written policies covering specific areas such as foreign exchange risk, interest rate risk, credit risk, liquidity risk, use of derivative 
financial instruments and non-derivative financial instruments, and investment of excess liquidity.

We have exposure to the following risks, which are described in more detail below:

•  credit risk;
•  liquidity risk;
•  interest rate risk;
•  currency risk;
•  commodity risk; and
•  capital risk.

(a) Credit risk
We are exposed to the risk of loss resulting from counterparties’ default on their commitments including failure to pay or make a delivery 
on a contract. This risk is inherent in our commercial business activities. We are exposed to credit risk on our cash and cash equivalents, 
derivative financial instruments, deposits with banks and financial institutions, as well as credit exposures to wholesale and retail 
customers, including outstanding receivables and committed transactions.

Treasury credit risk
Counterparty risk arises from the investment of surplus funds and from the use of derivative financial instruments. As at 31 March 2015, 
the following limits were in place for investments held with banks and financial institutions:

Triple ‘A’ G8 sovereign entities (AAA)
Triple ‘A’ vehicles (AAA)
Triple ‘A’ range institutions and non G8 sovereign entities (AAA)
Double ‘A+’ G8 sovereign entities (AA+)
Double ‘A’ range institutions (AA)
Single ‘A’ range institutions (A)

As at 31 March 2014 and 2015, we had a number of exposures to individual counterparties. In accordance with our treasury policies, 
counterparty credit exposure utilisations are monitored daily against the counterparty credit limits. Counterparty credit ratings and 
market conditions are reviewed continually with limits being revised and utilisation adjusted, if appropriate. Management does not 
expect any significant losses from non performance by these counterparties.

Commodity credit risk
The credit policy for commodity transactions is owned and monitored by the Executive Energy Risk Committee, under authority 
delegated by the Board and Executive Committee, and establishes controls and procedures to determine, monitor and minimise 
the credit risk of counterparties.

Wholesale and retail credit risk
Our principal commercial exposure in the UK is governed by the credit rules within the regulated codes: Uniform Network Code and 
Connection and Use of System Code. These set out the level of credit relative to the RAV for each credit rating. In the US, we are required 
to supply electricity and gas under state regulations. Our credit policies and practices are designed to limit credit exposure by collecting 
security deposits prior to providing utility services, or after utility service has commenced if certain applicable regulatory requirements 
are met. Collection activities are managed on a daily basis. Sales to retail customers are usually settled in cash, cheques, electronic bank 
payments or by using major credit cards. We are committed to measuring, monitoring, minimising and recording counterparty credit risk 
in our wholesale business. The utilisation of credit limits is regularly monitored and collateral is collected against these accounts when 
necessary. Management does not expect any significant losses of receivables that have not been provided for as shown in note 17.

Offsetting financial assets and liabilities
The following tables set out our financial assets and liabilities which are subject to offset and to enforceable master netting arrangements 
or similar agreements. The tables show the amounts which are offset and reported net in the statement of financial position. Amounts 
which cannot be offset under IFRS, but which could be settled net under terms of master netting agreements if certain conditions arise, 
and with collateral received or pledged, are shown to present National Grid’s net exposure.

Financial assets and liabilities on different transactions are only reported net if the transactions are with the same counterparty, a legal 
right of offset exists and the cash flows are intended to be settled on a net basis.

Amounts which do not meet the criteria for offsetting on the statement of financial position but could be settled net in certain circumstances 
principally relate to derivative transactions under ISDA agreements where each party has the option to settle amounts on a net basis in the 
event of default of the other party.

Commodity contracts that have not been offset on the balance sheet may be settled net in certain circumstances under ISDA or NAESB 
(North American Energy Standards Board) agreements.

National Grid has similar arrangements in relation to bank account balances and bank overdrafts; and trade payables and trade 
receivables which are subject to general terms and conditions. However, these balances are immaterial.

(b) Liquidity risk
Our policy is to determine our liquidity requirements by the use of both short-term and long-term cash flow forecasts. These forecasts are 
supplemented by a financial headroom analysis which is used to assess funding requirements for at least a 24 month period and maintain 
adequate liquidity for a continuous 12 month period.

We believe our contractual obligations, including those shown in commitments and contingencies in note 27 can be met from existing 
cash and investments, operating cash flows and other financings that we reasonably expect to be able to secure in the future, together 
with the use of committed facilities if required.

Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial 
information by the issuing entity and financial covenants such as restrictions on the level of subsidiary indebtedness. Failure to comply 
with these covenants, or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require 
repayment of some of our debt and may restrict our ability to draw upon our facilities or access the capital markets.

The following is an analysis of the contractual undiscounted cash flows payable under financial liabilities and derivative assets and liabilities 
as at the reporting date:

1.   The interest on borrowings is calculated based on borrowings held at 31 March without taking account of future issues. Floating rate interest is estimated using a forward interest rate curve 

as at 31 March. Payments are included on the basis of the earliest date on which the Company can be required to settle.

(c) Interest rate risk
National Grid’s interest rate risk arises from our long-term borrowings. Borrowings issued at variable rates expose National Grid to cash 
flow interest rate risk, partially offset by cash held at variable rates. Borrowings issued at fixed rates expose National Grid to fair value 
interest rate risk.

Our interest rate risk management policy is to seek to minimise total financing costs (being interest costs and changes in the market value 
of debt) subject to constraints. We do this by using fixed and floating rate debt and derivative financial instruments including interest rate 
swaps, swaptions and forward rate agreements.

We hold some borrowings on issue that are inflation linked. We believe that these provide a partial economic offset to the inflation risk 
associated with our UK inflation linked revenues.

The table in note 19 sets out the carrying amount, by contractual maturity, of borrowings that are exposed to interest rate risk before 
taking into account interest rate swaps.

During 2015 and 2014, net debt was managed using derivative instruments to hedge interest rate risk as follows:

2. Includes bank overdrafts.
3. The impact of 2015/16 (2014: 2014/15) maturing short-dated interest rate derivatives is included.

(d) Currency risk
National Grid operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with 
respect to the dollar. Foreign exchange risk arises from future commercial transactions, recognised assets and liabilities, and investments 
in foreign operations.

Our policy for managing foreign exchange transaction risk is to hedge contractually committed foreign currency cash flows over a 
prescribed minimum size. Where foreign currency cash flow forecasts are less certain, our policy is to hedge a proportion of such cash 
flows based on the probability of those cash flows occurring. Instruments used to manage foreign exchange transaction risk include 
foreign exchange forward contracts and foreign exchange swaps.

Our policy for managing foreign exchange translation risk relating to our net investment in foreign operations is to maintain a percentage of 
net debt and foreign exchange forwards so as to provide an economic offset of our cash flows arising in the foreign currency. The primary 
managed foreign exchange exposure arises from the dollar denominated assets and liabilities held by our US operations, with a further 
small euro exposure in respect of a joint venture investment.

During 2015 and 2014, derivative financial instruments were used to manage foreign currency risk as follows:

The carrying amounts of other financial instruments are denominated in the above currencies, which in most instances are the functional 
currency of the respective subsidiaries. Our exposure to dollars is due to activities in our US subsidiaries. We do not have any other 
significant exposure to currency risk on these balances.

(e) Commodity risk
We purchase electricity and gas to supply our customers in the US and to meet our own energy needs. Substantially all our costs of 
purchasing electricity and gas for supply to customers are recoverable at an amount equal to cost. The timing of recovery of these costs 
can vary between financial periods leading to an under- or over-recovery within any particular year that can lead to large fluctuations in 
the income statement. We follow approved policies to manage price and supply risks for our commodity activities.

Our energy procurement risk management policy and delegations of authority govern our US commodity trading activities for energy 
transactions. The purpose of this policy is to ensure we transact within pre-defined risk parameters and only in the physical and financial 
markets where we or our customers have a physical market requirement. In addition, state regulators require National Grid to manage 
commodity risk and cost volatility prudently through diversified pricing strategies. In some jurisdictions we are required to file a plan 
outlining our strategy to be approved by regulators. In certain cases we might receive guidance with regard to specific hedging limits.

Energy purchase contracts for the forward purchase of electricity or gas that are used to satisfy physical delivery requirements to 
customers or for energy that the Company uses itself meet the normal purchase, sale or usage exemption of IAS 39. They are, therefore, 
not recognised in the financial statements. Disclosure of commitments under such contracts is made in note 27.

We enter into forward contracts for the purchase of commodities, some of which do not meet the own use exemption for accounting 
purposes and hence are accounted for as derivatives. We also enter into derivative financial instruments linked to commodity prices, 
including index-linked futures, swaps and options contracts. These derivative financial instruments are used to manage market price 
volatility and are carried at fair value on the statement of financial position, with the mark-to-market changes reflected through earnings.

1.  Forward electricity purchases have terms up to three years. The contractual obligations under these contracts are £77m (2014: £106m).
2. Forward gas purchases have terms up to five years. The contractual obligations under these contracts are £26m (2014: £171m).
3. NYMEX gas futures have been offset with related margin accounts (see note 30(a)).

(f) Capital risk management
The capital structure of the Group consists of shareholders’ equity, as disclosed in the consolidated statement of changes in equity, and 
net debt (note 26). National Grid’s objectives when managing capital are: to safeguard our ability to continue as a going concern; to remain 
within regulatory constraints of our regulated operating companies; and to maintain an efficient mix of debt and equity funding thus achieving 
an optimal capital structure and cost of capital. We regularly review and manage the capital structure as appropriate in order to achieve 
these objectives.

Maintaining appropriate credit ratings for our regulated companies is an important aspect of our capital risk management strategy and 
balance sheet efficiency. As noted on page 22, we monitor our balance sheet efficiency using several metrics including our retained cash 
flow/net debt and interest cover. Interest cover for the year ended 31 March 2015 was 5.1 (2014: 4.1). Our long-term target range for 
interest cover is greater than 3.0, which we believe is consistent with single A range long-term senior unsecured debt credit ratings within 
our main UK operating companies, NGET and NGG, based on guidance from the rating agencies.

Financial Statements30. Financial risk management continued

(f) Capital risk management continued
In addition, we monitor the RAV gearing within each of NGET and the regulated transmission and distribution businesses within NGG. 
This is calculated as net debt expressed as a percentage of RAV, and indicates the level of debt employed to fund our UK regulated 
businesses. It is compared with the level of RAV gearing indicated by Ofgem as being appropriate for these businesses, at around 60 to 65%.

The majority of our regulated operating companies in the US and the UK (and one intermediate UK holding company), are subject to 
certain restrictions on the payment of dividends by administrative order, contract and/or licence. The types of restrictions that a company 
may have that would prevent a dividend being declared or paid unless they are met include:

•  dividends must be approved in advance by the relevant US state regulatory commission;
•  the subsidiary must have at least two recognised rating agency credit ratings of at least investment grade;
•  dividends must be limited to cumulative retained earnings, including pre-acquisition retained earnings;
•  National Grid plc must maintain an investment grade credit rating and if that rating is the lowest investment grade bond rating 

it cannot have a negative watch/review for downgrade notice by a credit rating agency;
•  the subsidiary must not carry on any activities other than those permitted by the licences;
•  the subsidiary must not create any cross-default obligations or give or receive any intra-group cross-subsidies; and
•  the percentage of equity compared with total capital of the subsidiary must remain above certain levels.

There is a further restriction relating only to the Narragansett Electric Company, which is required to maintain its consolidated net worth 
above certain levels.

These restrictions are subject to alteration in the US as and when a new rate case or rate plan is agreed with the relevant regulatory bodies 
for each operating company and in the UK through the normal licence review process.

As most of our business is regulated, at 31 March 2015 the majority of our net assets are subject to some of the restrictions noted above. 
These restrictions are not considered to be significantly onerous, nor do we currently expect they will prevent the planned payment of 
dividends in future in line with our dividend policy.

Some of our regulatory and bank loan agreements additionally impose lower limits for the long-term credit ratings that certain companies 
within the Group must hold. All the above requirements are monitored on a regular basis in order to ensure compliance. The Company has 
complied with all externally imposed capital requirements to which it is subject.

(g) Fair value analysis
The financial instruments included on the statement of financial position are measured at fair value. These fair values can be categorised 
into hierarchy levels that are representative of the inputs used in measuring the fair value. The best evidence of fair value is a quoted price 
in an actively traded market. In the event that the market for a financial instrument is not active, a valuation technique is used.

Our level 3 derivative financial instruments include cross-currency swaps with an embedded call option, currency swaps where the 
currency forward curve is illiquid and inflation linked swaps where the inflation curve is illiquid. In valuing these instruments a third-party 
valuation is obtained to support each reported fair value.

Our level 3 commodity contracts primarily consist of our forward purchases of electricity and gas where pricing inputs are unobservable, 
as well as other complex transactions. Complex transactions can introduce the need for internally developed models based on reasonable 
assumptions. Industry standard valuation techniques such as the Black-Scholes pricing model and Monte Carlo simulation are used for 
valuing such instruments. Level 3 is also applied in cases when optionality is present or where an extrapolated forward curve is considered 
unobservable. All published forward curves are verified to market data; if forward curves differ from market data by 5% or more they are 
considered unobservable.

The changes in value of our level 3 derivative financial instruments are as follows:

Financial Statements31. Borrowing facilities

To support our long-term liquidity requirements and provide backup to commercial paper and other borrowings, we agree loan facilities 
with financial institutions over and above the value of borrowings that may be required. These facilities have never been drawn, and our 
undrawn amounts are listed below.

At 31 March 2015, we had bilateral committed credit facilities of £2,094m (2014: £2,073m). In addition, we had committed credit facilities 
from syndicates of banks of £884m at 31 March 2015 (2014: £800m). All committed credit facilities were undrawn in 2015 and 2014. An 
analysis of the maturity of these undrawn committed facilities is shown below:

Undrawn committed borrowing facilities expiring:

Less than 1 year
In 1 to 2 years
In 2 to 3 years
In 3 to 4 years

Of the unused facilities at 31 March 2015, £2,666m (2014: £2,583m) was held as backup to commercial paper and similar borrowings, 
while £312m (2014: £290m) is available as backup to specific US borrowings.

In addition to the above the Group has an RPI-linked bank loan agreement totalling £1,500m with the European Investment Bank (EIB), 
which is currently undrawn.

Further information on our bonds can be found on the debt investor section of our website.

The Group comprises a large number of entities and it is not practical to include all of them in this list. This list therefore includes brief 
details for those principal companies which, in the Directors’ opinion, have a significant impact on the revenue, profit or assets of the 
Group. A full list of subsidiaries, joint ventures and associates is annexed to the Company’s Annual Return filed with the Registrar of 
Companies.

Our interests and activities are held or operated through subsidiaries, branches, joint arrangements or associates established in – and 
subject to the laws and regulations of – a number of different jurisdictions.

Financial Statements33. Sensitivities on areas of estimation and uncertainty

In order to give a clearer picture of the impact on our results or financial position of potential changes in significant estimates and 
assumptions, the following sensitivities are presented. These sensitivities are hypothetical, as they are based on assumptions and 
conditions prevailing at the year end, and should be used with caution. The effects provided are not necessarily indicative of the 
actual effects that would be experienced because our actual exposures are constantly changing.

The sensitivities in the tables below show the potential impact in the income statement (and consequential impact on net assets) for 
a range of different variables each of which have been considered in isolation (i.e. with all other variables remaining constant). There 
are a number of these sensitivities which are mutually exclusive and therefore if one were to happen, another would not, meaning a 
total showing how sensitive our results are to these external factors is not meaningful.

We are further required to show additional sensitivity analysis for changes in interest and exchange rates and these are shown separately 
in the subsequent table due to the additional assumptions that are made in order to produce meaningful sensitivity disclosures.

The sensitivities included in the tables below all have an equal and opposite effect if the sensitivity increases or decreases by the same 
amount unless otherwise stated. For example, a 10% increase in unbilled revenue at 31 March 2015 would result in an increase in the 
income statement of £60m and a 10% decrease in unbilled revenue would have the equal but opposite effect.

One year average change in useful economic lives (pre-tax):
Depreciation charge on property, plant and equipment
Amortisation charge on intangible assets

Estimated future cash flows in respect of provisions, change of 10% (pre-tax)

Assets and liabilities carried at fair value change of 10% (pre-tax):

Derivative financial instruments1
Commodity contract liabilities

Pensions and other post-retirement benefits2 (pre-tax):

UK discount rate change of 0.5%3
US discount rate change of 0.5%3
UK RPI rate change of 0.5%4
UK long-term rate of increase in salaries change of 0.5%5
US long-term rate of increase in salaries change of 0.5%5
UK change of one year to life expectancy at age 65
US change of one year to life expectancy at age 65
Assumed US healthcare cost trend rates change of 1%

Unbilled revenue at 31 March change of 10% (post-tax)

1.  The effect of a 10% change in fair value assumes no hedge accounting.
2. The changes shown are a change in the annual pension or other post-retirement benefit service charge and change in the defined benefit obligations.
3.  A change in the discount rate is likely to occur as a result of changes in bond yields and as such would be expected to be offset to a significant degree by a change in the value of the bond 

assets held by the plans.

4. The projected impact resulting from a change in RPI reflects the underlying effect on pensions in payment, pensions in deferment and resultant increases in salary assumptions.
5. This change has been applied to both the pre 1 April 2014 and post 1 April 2014 rate of increase in salary assumption.
6. Represents potential impact on fair values of commodity contracts only.

33. Sensitivities on areas of estimation and uncertainty continued

Pensions and other post-retirement benefits assumptions
Sensitivities have been prepared to show how the DB obligations and annual service costs could potentially be impacted by changes in 
the relevant actuarial assumption that were reasonably possible as at 31 March 2015. In preparing sensitivities the potential impact has 
been calculated by applying the change to each assumption in isolation and assuming all other assumptions remain unchanged. This is 
with the exception of RPI in the UK where the corresponding change to increases to pensions in payment, increases to pensions in 
deferment and increases in salary is recognised.

Financial instruments assumptions
Our financial instruments are sensitive to changes in market variables, being UK and US interest rates, the UK RPI and the dollar to sterling 
exchange rate. The changes in market variables impact the valuation of our borrowings, deposits, derivative financial instruments and 
commodity contracts. The analysis illustrates the sensitivity of our financial instruments to the changes in market variables.

The following main assumptions were made in calculating the sensitivity analysis:

•  the amount of net debt, the ratio of fixed to floating interest rates of the debt and derivatives portfolio, and the proportion of 

financial instruments in foreign currencies are all constant and on the basis of the hedge designations in place at 31 March 2015 
and 2014 respectively;

•  the statement of financial position sensitivity to interest rates relates only to derivative financial instruments and available-for-sale 
investments, as debt and other deposits are carried at amortised cost and so their carrying value does not change as interest 
rates move;

•  the sensitivity of accrued interest to movements in interest rates is calculated on net floating rate exposures on debt, deposits 

and derivative instruments;

•  changes in the carrying value of derivatives from movements in interest rates of designated cash flow hedges are assumed 

to be recorded fully within equity; and

•  changes in the carrying value of derivative financial instruments designated as net investment hedges from movements in interest 
rates are recorded in the income statement as they are designated using the spot rather than the forward translation method. 
The impact of movements in the dollar to sterling exchange rate are recorded directly in equity.

34. Additional disclosures in respect of guaranteed securities

We have three debt issuances (including preferred shares) that are listed on a US national securities exchange and are guaranteed 
by other companies in the Group. These guarantors commit to honour any liabilities should the company issuing the debt have any 
financial difficulties. In order to provide debt holders with information on the financial stability of the companies providing the guarantees, 
we are required to disclose individual financial information for these companies. We have chosen to include this information in the 
Group financial statements rather than submitting separate stand-alone financial statements. 

The following condensed consolidating financial information, comprising statements of comprehensive income, statements of financial 
position and cash flow statements, is given in respect of National Grid Gas plc (subsidiary guarantor), which became joint full and 
unconditional guarantor on 11 May 2004 with National Grid plc (parent guarantor) of the 6.625% Guaranteed Notes due 2018 issued in 
June 1998 by British Transco Finance Inc., then known as British Gas Finance Inc. (issuer of notes). Condensed consolidating financial 
information is also provided in respect of Niagara Mohawk Power Corporation as a result of National Grid plc’s guarantee, dated 
29 October 2007, of Niagara Mohawk’s 3.6% and 3.9% issued preferred shares. National Grid Gas plc, British Transco Finance Inc., 
and Niagara Mohawk Power Corporation are wholly-owned subsidiaries of National Grid plc.

The following financial information for National Grid plc, National Grid Gas plc, British Transco Finance Inc., and Niagara Mohawk Power 
Corporation on a condensed consolidating basis is intended to provide investors with meaningful and comparable financial information 
and is provided pursuant to various rules including Rule 3-10 of Regulation S-X in lieu of the separate financial statements of each 
subsidiary issuer of public debt securities.

This financial information should be read in conjunction with the other disclosure in these financial statements.

prepared in accordance with applicable UK accounting and 
financial reporting standards and the Companies Act 2006. They 
have been prepared on an historical cost basis, except for the 
revaluation of financial instruments, and are presented in pounds 
sterling, which is the currency of the primary economic environment 
in which the Company operates. The 2014 comparative financial 
information has also been prepared on this basis.

These individual financial statements have been prepared on a 
going concern basis, which presumes that the Company has 
adequate resources to remain in operation, and that the Directors 
intend it to do so, for at least one year from the date the financial 
statements are signed. Further details of the Directors’ assessment 
are set out on page 54.

The Company has not presented its own profit and loss account 
as permitted by section 408 of the Companies Act 2006.

The Company has taken advantage of the exemptions in FRS 8 
‘Related Party Disclosures’ from disclosing transactions with other 
members of the National Grid plc group of companies.

In accordance with exemptions under FRS 29 ‘Financial 
Instruments: Disclosures’, the Company has not presented the 
financial instruments disclosures required by the standard, as 
disclosures which comply with the standard are included in the 
consolidated financial statements.

B. Fixed asset investments
Investments held as fixed assets are stated at cost less any 
provisions for impairment. Investments are reviewed for impairment 
if events or changes in circumstances indicate that the carrying 
amount may not be recoverable. Impairments are calculated such 
that the carrying value of the fixed asset investment is the lower of 
its cost or recoverable amount. Recoverable amount is the higher 
of its net realisable value and its value-in-use.

C. Tax
Current tax for the current and prior periods is provided at the 
amount expected to be paid or recovered using the tax rates and 
tax laws that have been enacted or substantively enacted by the 
balance sheet date.

Deferred tax is provided in full on timing differences which result 
in an obligation at the balance sheet date to pay more tax, or the 
right to pay less tax, at a future date, at tax rates expected to 
apply when the timing differences reverse based on tax rates 
and tax laws that have been enacted or substantively enacted 
by the balance sheet date. Timing differences arise from the 
inclusion of items of income and expenditure in tax computations 
in periods different from those in which they are included in the 
financial statements.

Deferred tax assets are recognised to the extent that it is regarded 
as more likely than not that they will be recovered. Deferred tax 
assets and liabilities are not discounted.

D. Foreign currencies
Transactions in currencies other than the functional currency of the 
Company are recorded at the rates of exchange prevailing on the 
dates of the transactions. At each balance sheet date, monetary 
assets and liabilities that are denominated in foreign currencies are 
retranslated at closing exchange rates. Gains and losses arising on 
retranslation of monetary assets and liabilities are included in the 
profit and loss account.

E. Financial instruments
The Company’s accounting policies under UK GAAP, namely 
FRS 25 ‘Financial Instruments: Presentation’, FRS 26 ‘Financial 
Instruments: Measurement’ and FRS 29 ‘Financial Instruments: 
Disclosures’, are the same as the Group’s accounting policies 
under IFRS, namely IAS 32 ‘Financial Instruments: Presentation’, 
IAS 39 ‘Financial Instruments: Recognition and Measurement’ and 
IFRS 7 ‘Financial Instruments: Disclosures’. The Company applies 
these policies only in respect of the financial instruments that it has, 
namely investments, derivative financial instruments, debtors, cash 
at bank and in hand, borrowings and creditors.

The policies are set out in notes 13, 15, 17, 18, 19 and 20 to the 
consolidated financial statements. The Company is taking the 
exemption for financial instruments disclosures, because IFRS 7 
disclosures are given in notes 30 and 33 to the consolidated 
financial statements.

F. Hedge accounting
The Company applies the same accounting policy as the Group 
in respect of fair value hedges and cash flow hedges. This policy 
is set out in note 15 to the consolidated financial statements.

G. Parent Company guarantees
The Company has guaranteed the repayment of the principal sum, 
any associated premium and interest on specific loans due by 
certain subsidiary undertakings primarily to third parties. In the event 
of default or non performance by the subsidiary, the Company 
recognises such guarantees as insurance contracts, at fair value 
with a corresponding increase in the carrying value of the investment.

H. Share awards to employees of subsidiary 
undertakings
The issuance by the Company to employees of its subsidiaries of 
a grant over the Company’s options represents additional capital 
contributions by the Company to its subsidiaries. An additional 
investment in subsidiaries results in a corresponding increase in 
shareholders’ equity. The additional capital contribution is based 
on the fair value of the option at the date of grant, allocated over the 
underlying grant’s vesting period. Where payments are subsequently 
received from subsidiaries, these are accounted for as a return of 
a capital contribution and credited against the Company’s 
investments in subsidiaries. The Company has no employees.

I. Dividends
Interim dividends are recognised when they are paid to the 
Company’s shareholders. Final dividends are recognised when 
they are approved by shareholders.

J. Directors’ remuneration
Full details of directors’ remuneration are disclosed on pages 60 
to 75.

During the year there was a capital contribution of £20m (2014: £20m) which represents the fair value of equity instruments granted 
to subsidiaries’ employees arising from equity-settled employee share schemes. During the year ended 31 March 2014, the Company 
acquired a further 98,851 ordinary shares of £1 each in National Grid (US) Holdings Limited for a total consideration of £606m. 

The names of the principal subsidiary undertakings, joint ventures and associates are included in note 32 to the consolidated financial

The business in detail continued

UK regulation
Our licences are established under the Gas Act 1986 and 
Electricity Act 1989, as amended (the Acts). They require us to 
develop, maintain and operate economic and efficient networks 
and to facilitate competition in the supply of gas and electricity in 
Great Britain. They also give us statutory powers. These include 
the right to bury our pipes or cables under public highways and 
the ability to use compulsory powers to purchase land so we can 
conduct our business.

Our networks are regulated by Ofgem, which has established 
price control mechanisms that set the amount of revenue that our 
regulated businesses can earn. Price control regulation is designed 
to make sure our interests, as a monopoly, are balanced with those 
of our customers. Ofgem allows us to charge reasonable, but not 
excessive, prices. This gives us a future level of revenue that is 
sufficient to meet our statutory duties and licence obligations, 
and makes a reasonable return on our investment.

The price control includes a number of mechanisms designed to 
help achieve its objectives. These include financial incentives that 
encourage us to: 

•   continuously improve the cost and effectiveness of our services; 
•  manage and operate our networks efficiently; 
•  deliver high-quality services to our customers and wider 

stakeholder community; and

•  invest in developing the network in a way that ensures long-term 

security of supply.

Our UK Electricity Transmission (UK ET), UK Gas Transmission 
(UK GT) and UK Gas Distribution (UK GD) businesses operate 
under eight separate price controls in the UK. These comprise two 
for our UK ET operations, one covering our role as transmission 
owner (TO) and the other for our role as system operator (SO); 
two for our UK GT operations, again one as TO and one as SO; 
and one for each of our four regional gas distribution networks. 
While each of the eight price controls may have differing terms, 
they are based on a consistent regulatory framework.

In addition to the eight price controls, our LNG storage business 
has a price control covering some aspects of its operations. 
There is also a tariff cap price control applied to certain elements 
of domestic metering and daily meter reading activities carried out 
by National Grid Metering.

Interconnectors derive their revenues from congestion revenues. 
Congestion revenues depend on the existence of price 
differentials between markets at either end of the interconnector. 
European legislation governs how capacity is allocated. It requires 
all interconnection capacity to be allocated to the market 
through auctions. 

There are a range of different regulatory models available for 
interconnector projects. These involve various levels of regulatory 
insight ranging from fully merchant (the project is reliant on 
revenues selling interconnector capacity) to ‘cap and floor’ 
(where revenues above the cap are returned to system users 
and revenues below the floor are topped by system users thus 
reducing the overall project risk).

RIIO price controls
On 1 April 2013, our UK regulator introduced a new regulatory 
framework called RIIO (revenue = incentives + innovation + 
outputs), which lasts for eight years. The building blocks of the 
RIIO price control are broadly similar to the historical price controls 
used in the UK. However, there are some significant differences 
in the mechanics of the calculations.

How is revenue calculated?
Under RIIO the outputs we deliver are clearly articulated and are 
integrally linked to the calculation of our allowed revenue. These 
outputs have been determined through an extensive consultation 
process, which has given stakeholders a greater opportunity to 
influence the decisions. The clarity around outputs should lead 
to greater transparency in how we deliver them.

The six output categories are:

Safety: ensuring the provision of a safe energy network. 

Reliability (and availability): promoting networks capable of 
delivering long-term reliability, as well as minimising the number 
and duration of interruptions experienced over the price control 
period, and ensuring adaptation to climate change.

Environmental impact: encouraging companies to play their role 
in achieving broader environmental objectives – specifically, 
facilitating the reduction of carbon emissions – as well as 
minimising their own carbon footprint.

Customer and stakeholder satisfaction: maintaining high levels of 
customer satisfaction and stakeholder engagement, and improving 
service levels.

Customer connections: encouraging networks to connect 
customers quickly and efficiently.

Social obligations (UK Gas Distribution only): extending the gas 
network to communities that are fuel poor where it is efficient to 
do so, and introducing measures to address carbon monoxide 
poisoning incidents.

Within each of these output categories are a number of primary 
and secondary deliverables, reflecting what our stakeholders 
want us to deliver over the coming price control period. The nature 
and number of these deliverables varies according to the output 
category, with some being linked directly to our allowed revenue, 
some linked to legislation, and others having only a reputational 
impact. Ofgem, using information we have submitted, along 
with independent assessments, determines the efficient level 
of expected costs necessary to deliver them. Under RIIO this is 
known as totex, which is total allowable expenditure, and is similar 
to the sum of what was controllable opex, capex (and repex 
for UK Gas Distribution) under the previous price control periods.

A number of assumptions are necessary in setting these outputs, 
such as certain prices or the volumes of work that will be needed. 
Consequently, there are a number of uncertainty mechanisms 
within the RIIO framework that can result in adjustments to totex 
if actual prices or volumes differ from the assumptions. These 
mechanisms protect us and our customers from windfall gains

Additional InformationWhere we under- or over-spend the allowed totex for reasons that 
are not covered by uncertainty mechanisms, there is a sharing 
factor. This means the under- or over-spend is shared between 
us and customers through an adjustment to allowed revenues in 
a future year. This sharing factor provides an incentive for us to 
provide the outputs efficiently, as we are able to keep a portion 
of the savings, with the remainder benefiting our customers.

This sharing factor is one of the ways that RIIO has given innovation 
more prominence. Innovation includes traditional areas such as 
new technologies, as well as the broader challenge of finding new 
ways of working to deliver outputs more efficiently. This broader 
challenge has an impact on everyone in our business.

Totex is then split between fast and slow money – a new concept 
under RIIO, based on a specified percentage. Fast money 
represents the amount of totex we are able to recover in the 
current year. Slow money is added to our RAV. For more details 
on the sharing factors under RIIO, please see the table below.

In addition to fast money, in each year we are allowed to collect 
a depreciation of and a return on our RAV.

The cost of capital allowed under RIIO is as follows:

This works in a similar way to the previous price control. 
However, there have been changes to the asset lives for electricity 
transmission (transition from 20 years to 45 years evenly across the 
RIIO period) and the depreciation calculation for UK GD (changed 
from 45 years straight line to 45 years sum of digits for assets 
added post 2002). We are also allowed to collect additional 
revenues related to non-controllable costs and incentives.

The incentive mechanisms can increase or decrease our allowed 
revenue and result from our performance against various 
measures related to our outputs. RIIO has introduced new incentive 
mechanisms as a way to provide further incentives to align our 
objectives with those of our customers and other stakeholders. 
For example, performance against our customer satisfaction 
targets can have a positive or negative effect of up to 1% of allowed 
annual revenues. Incentives will normally affect our revenues two 
years after the year of performance. 

The sharing factor means that any over- and under-spend is shared 
between the businesses and consumers. The shared figures 
displayed are the sharing factors that apply to the UK ET, UK GT 
and UK GD.

Sharing

1.  Fast money allows network companies to recover a percentage of total expenditure within a one year period. 
2.  Slow money is where costs are added to RAV and, therefore, revenues are recovered slowly (e.g. over 20 years) from both current and future consumers. 
3.  The Baseline is the expenditure that is funded through ex ante allowances whereas the Uncertainty adjusts the allowed expenditure automatically where the level outputs delivered differ from 

the baseline level, or if triggered by an event.

US Regulation
Regulators
In the US, public utilities’ retail transactions are regulated by 
state utility commissions. The commissions serve as economic 
regulators, approving cost recovery and authorised rates of return. 
The state commissions establish the retail rates to recover the cost 
of transmission and distribution services, and focus on services 
and costs within their jurisdictions. They also serve the public 
interest by making sure utilities provide safe and reliable service 
at just and reasonable prices. The commissions establish service 
standards and approve public utility mergers and acquisitions. 

Utilities are regulated at the federal level (FERC) for wholesale 
transactions, such as interstate transmission and wholesale 
electricity sales, including rates for these services. FERC also 
regulates public utility holding companies and centralised service 
companies, including those of our US businesses.

Regulatory process
The US regulatory regime is premised on allowing the utility the 
opportunity to recover its cost of service and earn a reasonable 
return on its investments as determined by the commission. Utilities 
submit formal rate filings (‘rate cases’) to the relevant state regulator 
when additional revenues are necessary to provide safe, reliable 
service to customers. Utilities can be compelled to file a rate case 
due to complaints filed with the commission or at the commission’s 
own discretion.

The rate case is litigated with parties representing customer and 
other interests. In the states in which we operate, it can take nine 
to thirteen months for the commission to render a final decision. 
The utility is required to prove that the requested rate change is 
prudent and reasonable, and the requested rate plan can span 
multiple years. Unlike the state processes, the federal regulator 
has no specified timeline for adjudicating a rate case, but typically 
makes a final decision retroactive when the case is completed. 

Gas and electricity rates are established from a revenue 
requirement, or cost of service, equal to the utility’s total cost 
of providing distribution or delivery service to its customers, 
as approved by the commission in the rate case. This revenue 
requirement includes operating expenses, depreciation, taxes and 
a fair and reasonable return on shareholder capital invested in 
certain components of the utility’s regulated asset base, typically 
referred to as its rate base. 

The final revenue requirement and rates for service are approved 
in the rate case decision. The revenue requirement is derived from 
a comprehensive study of the utility’s total costs during a recent 
12 month period of operations, referred to as a test year. Each 
commission has its own rules and standards for adjustments to 
the test year and may include forecasted capital investments. 
These adjustments are intended to arrive at the total costs 
expected in the first year new rates will be in effect, or the rate year.

Our rate plans
Each operating company has a set of rates for service.  
We have three electric distribution operations (upstate New York, 
Massachusetts, and Rhode Island) and six gas distribution 
networks (upstate New York, New York City, Long Island, 
Massachusetts (two), and Rhode Island).

Our operating companies have revenue decoupling mechanisms 
that de-link the companies’ revenues from the quantity of energy 
delivered and billed to customers. These mechanisms remove 
the natural disincentive utility companies have for promoting and 
encouraging customer participation in energy efficiency programmes 
that lower energy end use and thus distribution volumes. 

Our rate plans are designed to a specific allowed RoE, by 
reference to an allowed operating expense level and rate base. 
Some rate plans include earnings sharing mechanisms that allow 
us to retain a proportion of the earnings above our allowed RoE, 
achieved through improving efficiency, with the balance 
benefiting customers.

In addition, our performance under certain rate plans is subject 
to service performance targets. We may be subject to monetary 
penalties in cases where we do not meet those targets.

One measure used to monitor the performance of our regulated 
businesses is a comparison of achieved RoE to allowed RoE, with 
a target that the achieved should be equal to or above the allowed. 
However, this measure cannot be used in isolation, as there are a 
number of factors that may prevent us from achieving that target. 
These factors include financial market conditions, regulatory lag 
and decisions by the regulator preventing cost recovery in rates 
from customers.

We work to increase achieved RoE through: productivity 
improvements; positive performance against incentives or earned 
savings mechanisms such as energy efficiency programmes, 
where available; and filing a new rate case when achieved returns 
are lower than the Company could reasonably expect to attain 
through a new rate case.

Additional Information 
 
Features of our rate plans
We bill our customers for their use of electricity and gas services. 
Customer bills typically comprise a commodity charge, covering 
the cost of the electricity or gas delivered, and charges covering 
our delivery service. With the exception of residential gas 
customers in Rhode Island, our customers are allowed to select 
an unregulated competitive supplier for the supply component 
of electricity and gas utility services. A substantial proportion of 
our costs, in particular electricity and gas commodity purchases, 
are pass-through costs, meaning they are fully recoverable from 
our customers. These pass-through costs are recovered through 
separate charges to customers that are designed to recover those 
costs with no profit. Rates are adjusted from time to time to make 
sure that any over- or under-recovery of these costs is returned to, 
or recovered from, our customers. 

Our FERC-regulated transmission companies use formula rates 
(instead of rate cases) to set rates annually to recover their cost of 
service. Through the use of annual true-ups, formula rates recover 
our actual costs incurred and the allowed RoE based on the actual 
transmission rate base each year. The company must make annual 
formula rate filings documenting the revenue requirement, which 
customers can review and challenge. 

Revenue for our wholesale transmission businesses in New 
England and New York is collected from wholesale transmission 
customers, who are typically other utilities and include our own 
New England electricity distribution businesses. With the exception 
of upstate New York, which continues to combine retail 
transmission and distribution rates to end-use customers, these 
wholesale transmission costs are incurred by distribution utilities on 
behalf of their customers and are fully recovered as a pass-through 
from end-use customers as approved by each state commission.

Our Long Island generation plants sell capacity to LIPA under 
15 year and 25 year power supply agreements, and within 
wholesale tariffs approved by FERC. Through the use of cost-
based formula rates these long-term contracts provide a similar 
economic effect to cost of service rate regulation.

US regulatory filings
The objectives of our rate case filings are to make sure we have the 
right cost of service with the ability to earn a fair and reasonable 
rate of return, while providing safe, reliable and economical service 
to our customers. In order to achieve these objectives and to 
reduce regulatory lag, we have been requesting structural changes, 
such as revenue decoupling mechanisms, capital trackers, 
commodity-related bad debt true-ups and pension and other 
post-employment benefit true-ups, separately from base rates. 
These terms are explained below the table on page 172. 

Below we summarise significant developments in rate filings and 
the regulatory environment during the year. We completed the final 
stabilisation upgrade to our new financial systems in July 2014. The 
new systems will facilitate future regulatory filings and capture the 
benefit of the increased investments in asset replacement, network 
reliability and customer growth. Planning has started to prepare 
suitable ‘test years’ to support new regulatory filings. We expect 
to make a number of such filings over the next two to three years 
to update the capital investment allowances and rate base across 
many of our businesses. Specifically, we anticipate that KEDLI, 
KEDNY, and Massachusetts Electric will file applications for new 
rate plans with their regulators during the 12 months ending 
31 March 2016. Moreover, as part of current regulatory initiatives, 
we will file proposals for investments in grid modernisation in 
Massachusetts and for innovative technology deployments and 
service offerings as part of the Reforming the Energy Vision effort 

in New York. Effective 1 April 2015, we implemented changes to 
our US management structure to strengthen our jurisdictional focus 
and address recommendations made by our regulators, including 
giving jurisdictional presidents more authority over operations and 
other functions.

Massachusetts
Capital investment programmes
Most recently, on the electricity side, MADPU allowed 
approximately $12 million into rates effective from 1 March 2015, 
related to $170 million of plant investments made in 2013.

On the gas side, MADPU allowed approximately $15 million into 
rates effective from 1 November 2014, related to $134 million of 
plant investment made in 2013. Additionally, recent legislation 
in Massachusetts grants us greater ability to cost effectively 
accelerate the replacement of our ageing gas infrastructure by 
receiving concurrent cost recovery for eligible capital investments. 
We submitted a plan to MADPU on 31 October 2014 to replace all 
eligible ageing gas infrastructure on our system within 20 years 
by increasing the annual replacement rate by approximately 50% 
within the next 10 years, and then maintaining this replacement rate 
for the remainder of the programme. On 30 April 2015, MADPU 
approved our proposal to place an additional $9.7 million into rates 
effective from 1 May 2015, related to $175 million of anticipated 
investments in 2015 under this accelerated pipe replacement plan. 

Solar investment legislation
Recent legislation extended our ability to construct, own and 
operate a total of up to 25 MW of solar facilities within our electricity 
service territory if the facilities are constructed by 30 June 2016. On 
28 June 2014, MADPU approved our proposal for up to 20 MW of 
solar facilities, in addition to the 4.6 MW of solar generation that we 
already own and operate under the same legislation. MADPU also 
pre-approved an amount not to exceed $97.6 million for ownership 
costs, lease expenses and property tax expenses associated with 
the solar facilities. We have entered into contracts with developers 
to deliver constructed solar generation facilities by 2015, and will 
petition MADPU for cost recovery in 2016 once the solar facilities 
become operational. 

Storm fund recovery
The Massachusetts electricity business collects $4.3 million 
annually in base rates to credit towards a storm fund devoted to 
fund major storm restoration efforts. The severity and frequency of 
storms in Massachusetts over the last few years left our storm fund 
in a deficit position of approximately $212 million. On 3 May 2013, 
MADPU allowed us to begin collecting $40 million annually for three 
years, and an additional $7.3 million from 1 July 2014, towards 
the replenishment of the storm fund, subject to a review of the 
prudency of the underlying costs. That review is under way, with 
evidentiary hearings scheduled for May 2015. The funding of the 
remaining deficit will be addressed as part of the prudency review 
and in future rate proceedings, if necessary. 

Storm management audit
MADPU’s December 2012 order regarding our performance 
during Tropical Storm Irene and the October 2011 snowstorm 
required us to undergo an independent audit regarding our storm 
management. MADPU adopted the auditor’s 30 recommendations, 
which included items such as improving emergency response 
training and tracking of training, designating additional personnel 
for storm roles, and considering the expanded use of technology 
and communication tools. The Company has already implemented 
12 of the recommendations and is in the process of implementing 
the remaining recommendations.

Grid modernisation
MADPU is increasingly focused on improving service and reliability 
to customers, with a focus on greater choice for customers and 
integrating distributed energy resources. MADPU has directed the 
Company to file a grid modernisation plan in August 2015 that 
demonstrates how the Company will make measurable progress 
towards reducing the effect of outages, optimising demand, 
integrating distributed resources and improving workforce and 
asset management. The grid modernisation plan represents a 
new capital investment opportunity for the Company. MADPU 
established criteria that, if met, would allow the capital costs 
from the plan to be recovered through a separate capital 
recovery mechanism.

Additionally, the Company’s Worcester, Massachusetts Smart 
Energy Solutions pilot began on 1 January 2015. The pilot is 
testing grid modernisation technologies for approximately 15,000 
customers, with a goal of reducing peak and average loads by 5%. 
The Company has an opportunity to earn a performance incentive 
if load reduction exceeds 5%. The Company filed on 15 September 
2014 to recover $11 million of costs incurred in 2012 and 2013 to 
implement this pilot. MADPU is currently reviewing the Company’s 
request and a decision is expected in early 2016.

Service quality
MADPU issued its final order and service quality guidelines for all 
gas and electricity companies on 22 December 2014. The order 
shifted the goal of the service quality guidelines from preventing 
the deterioration of performance to improved service quality. The 
reasons stated by MADPU included that: the companies are able 
to achieve higher levels of service quality than in 2002, when the 
guidelines were first implemented; customers expect improved 
levels of service quality; and advances in available technologies 
and the expected grid modernisation efforts of the electricity 
companies will help them meet the new standards and at a more 
reasonable cost. In shifting the goals of service quality, MADPU 
made changes to the current service quality structure, including 
removing financial offsets to penalties, setting state-wide 
benchmarks and changing the calculation of benchmarks and 
penalties. The new guidelines are effective from 1 January 2015. 
However, there is a motion for clarification and reconsideration 
currently pending before MADPU on this matter. 

New York
Upstate New York 2012 rate plan filing
Effective from 1 April 2014, the upstate New York electricity and 
gas businesses entered the second year of their three year rate 
plan. The rate plan provides an increase in the electricity delivery 
revenue requirement of $51.4 million and $28.3 million for rate years 
two and three, respectively. For the gas operations, the rate plan 
provides an increase of $5.9 million and $6.3 million in rate years 
two and three, respectively. 

Reforming the Energy Vision (REV)
In April 2014, the NYPSC instituted the REV proceeding, which 
considers options for a new regulatory and operational model for 
electricity utilities that includes a greater emphasis on incorporating 
distributed energy resources (DER) via market mechanisms. The 
NYPSC envisions a new role for utilities as distributed system 
platform (DSP) providers who create markets for DER and more 
fully integrate DER in distribution system operations and planning. 
The REV proceeding’s objectives include: enhanced customer 
energy choices and control; improved electricity system efficiency, 
reliability, and resiliency; and cleaner more diverse electricity 
generation. In February 2015, the NYPSC issued an order 
addressing various technical, policy, and market design issues. 

170

The NYPSC is expected to address ratemaking issues in 2015. 
Implementation of the DSP role and greater DER integration will 
probably require incremental investments in utility infrastructure.

2013 New York gas management audit
In October 2014, the NYPSC issued a report on the results of the 
comprehensive management and operations audit of National 
Grid’s three New York gas distribution utilities. New York law 
requires periodic management audits of all utilities at least once 
every five years. We last underwent a management audit in 2009 
when the NYPSC audited Niagara Mohawk’s electricity business. 

The audit found that our operations performed well in providing 
reliable gas service and noted strength in operations, network 
planning, project management, work management, load 
forecasting, supply procurement and customer systems support. 
The audit report offered 31 recommendations aimed at promoting 
improvement in the performance of our New York gas businesses, 
including recommendations around strengthening of the National 
Grid US jurisdictional operating model, enhancing the service level 
agreements between the operating companies and supporting 
functions and corporate governance. We generally accept the 
recommendations presented in the report, and are currently 
working to implement the recommendations in a manner that 
will deliver the greatest value to our gas customers. To address 
the recommendation that the National Grid USA Board include at 
least one independent director, Therese Esperdy was elected to 
the Board of Directors with effect from 1 May 2015. In our next 
major gas rate proceeding, the NYPSC will consider our 
effectiveness in implementing the audit recommendations 
and seek to reflect the costs and savings associated with the 
recommendations in rates.

KEDLI gas investment plan
In June 2014, KEDLI petitioned the NYPSC for approval of a 
deferral mechanism related to a proposed gas infrastructure 
investment programme. In December 2014, the NYPSC approved 
two gas investment plans for calendar years 2015 and 2016, one 
for leak-prone pipe capital expenditures (capped at $211.7 million 
in total) and one for gas service expansion expenditures (capped 
at $202.9 million in total). The NYPSC approved a surcharge to 
begin recovery of the deferred leak-prone pipeline investment 
costs, allowing for the recovery up to a total of $23.4 million 
through a surcharge effective from 1 April 2015 until the end 
of 2016. KEDLI received approval to establish a new deferral 
accounting mechanism for the balance of the approved costs 
not covered by the surcharge.

KEDNY rate plan extension
In June 2013, the NYPSC approved a two year extension of 
KEDNY’s five year rate settlement, extending the rate plan until 
the end of 2014. The NYPSC modified KEDNY’s capital tracker 
to be a downward-only net utility plant reconciliation mechanism, 
covering the cumulative two year term ending 31 December 2014. 
The extension of KEDNY’s rate settlement included increased 
capital investment allowances for 2013 and 2014. 

Rhode Island
Rhode Island 2014/15 electricity and gas infrastructure, 
safety and reliability (ISR) plans 
State law provides our Rhode Island gas and electricity operating 
divisions with rate mechanisms that allow for the recovery of capital 
investment, including a return, and certain expenses outside base 
rate proceedings through the submission of annual ISR plans. 

Additional InformationIn December 2014, we filed with the RIPUC for review and 
approval of our annual ISR plans for the electricity and gas 
systems. RIPUC approved the 2016 ISR plans on 31 March 2015. 
The electricity ISR plan encompasses a $73.3 million spending 
programme for capital investment and $12.1 million for operating 
and maintenance expenses for vegetation management and 
inspection and maintenance. The gas ISR plan encompasses 
$76.8 million for capital investment and incremental operation  
and maintenance expense for the hiring and training of additional 
personnel to support increases in leak-prone pipe replacement.

Rhode Island Renewable Energy Growth Program
In June 2014, the Rhode Island legislature enacted legislation to 
facilitate and promote installation of distributed renewable energy 
generation. As a result, in November 2014, we filed with RIPUC 
a proposal to implement the Rhode Island Renewable Energy 
Growth Program, which replaces our current programme and will 
create a feed-in-tariff (FIT) programme to support a total of 160 MW 
of renewable distributed generation projects over a five year period. 
The FIT payments will be determined via competitive solicitations 
for larger projects. The current programme provides long-term 
contracts, or power purchase agreements, to renewable energy 
projects. RIPUC approved the new programme on 31 March 2015. 
Under Rhode Island law, we can recover the incremental costs 
associated with the programme and are entitled to earn incentives 
equal to 1.75% of the gross payments made under the FIT. 

FERC
Complaints on New England transmission allowed RoE
In September 2011, December 2012 and July 2014, complaints 
were filed with FERC against certain transmission owners, including 
our New England electricity transmission business, to lower the 
base RoE from the FERC approved rate of 11.14%. In orders 
addressing the September 2011 complaint issued in June 2014, 
October 2014 and March 2015, FERC set the base RoE for the first 
complaint’s 15 month historical refund period and for a prospective 
period beginning in October 2014 at 10.57%. In these orders, FERC 
also found that the total or maximum RoE for our New England 
transmission business, including various RoE incentive adders 
authorised by FERC, cannot exceed 11.74% during these periods.

FERC has scheduled hearings on the December 2012 and July 
2014 New England RoE complaints in June 2015, with non-binding 
preliminary findings due by the end of 2015. A FERC order acting 
on these preliminary findings is not expected until the end of 2016.

Complaints on New York transmission allowed RoE
In September 2012, November 2012 and February 2014, 
complaints were filed with FERC against our New York electricity 
transmission subsidiary to lower the total RoE from the FERC 
approved rate of 11.5% and to modify certain other aspects of our 
New York transmission formula rates. In September 2014, FERC 
set these three complaints for settlement and hearing procedures. 
In December 2014, we reached a settlement agreement in principle 
with the complainants to resolve these complaints. In May 2015, 
FERC approved the uncontested settlement agreement.

Short-term borrowing authorisation
In October 2014, National Grid filed an application with FERC on 
behalf of all electricity public utility subsidiaries, with the exception 
of Massachusetts Electric Company (MECo), seeking to re-
establish the Commission’s authorisation to issue short-term debt, 
as required by Section 204 of the Federal Power Act. National 
Grid’s short-term borrowing authorisation had expired on 30 
November 2013, as issues related to the implementation of the US 
enterprise resource planning system had rendered National Grid 
temporarily unable to provide FERC with the financial reports 

required for such approval. FERC granted the application in 
December 2014. MECo was omitted from the application because 
it did not satisfy the interest coverage calculation typically required 
for approval. National Grid intends to file on behalf of MECo 
as soon as practicable, and in the interim MECo’s short-term 
cash needs will be met through capital contributions in the form 
of equity.

New York Transco
On 14 November 2014, the four New York investor-owned utilities 
(IOUs), including Niagara Mohawk Power Corporation, formed NY 
Transco LLC, a New York company whose sole business will be to 
plan, develop, construct and own major new high voltage electricity 
transmission projects across New York State. In early December 
2014, the four IOUs and NY Transco filed on behalf of NY Transco 
an application with FERC to establish a formula rate, rate incentives 
and cost allocation for a portfolio of five new transmission projects 
with a combined estimated total cost of over $1.7 billion. A number 
of entities intervened in the docket and challenged various aspects 
of the application. In April 2015, FERC approved certain elements 
of our filing (including some rate incentives), rejected others, and 
set the remainder for hearing and settlement.

New England gas and electricity interdependency
The region’s electricity and gas systems have become increasingly 
interdependent as the region’s reliance on gas-fired electricity 
generation has grown without commensurate pipeline 
infrastructure expansion, resulting in severe constraints at certain 
times of the year. These constraints have restricted gas availability 
for generation and decreased electricity reliability. They have also 
resulted in significant increases to spot gas prices for electricity 
generation, driving significant increases to the region’s wholesale 
and retail electricity costs. To address this challenge, New 
England’s governors have established an initiative envisaging 
coordinated strategic infrastructure investments focused on 
expanding the region’s energy portfolio. 

We are working with representatives from several states, other 
regional electricity and gas utilities, interstate gas pipelines, state 
regulators, and FERC in realising the governors’ goals. We have put 
forward structural proposals which would support the development 
of additional gas pipeline infrastructure to serve the region’s needs 
and are also developing electricity transmission proposals to 
increase the ability to deliver clean low carbon energy to enable 
a balanced solution to the region’s energy needs. 

FERC Order 1000
Issued in 2011, Order 1000 was FERC’s major policy order 
intended to foster regional and inter-regional transmission planning, 
address transmission needs driven by public policy requirements 
and increase competition in the electric transmission industry. In 
2014 and 2015, FERC issued orders on filings made by the New 
York and New England system operators to comply with Order 
1000 and continue to implement a package of reforms addressing 
transmission planning and cost allocation. A federal court upheld 
key provisions of Order 1000 against legal challenges in an August 
2014 decision. Policies to comply with Order 1000 have been in 
effect in New York since January 2014 and became effective in 
New England in May 2015. The competitive transmission planning 
processes instituted under Order 1000 have opened National 
Grid’s service territory to competition from non-incumbent 
transmission developers and also created opportunities for 
National Grid to compete for transmission projects outside of the 
Company’s current geographic footprint.

†Revenue decoupling
A mechanism that removes the link between a utility’s revenue 
and sales volume so that the utility is indifferent to changes 
in usage. Revenues are reconciled to a revenue target, with 
differences billed or credited to customers. Allows the utility 
to support energy efficiency.

‡Capital tracker
A mechanism that allows for the recovery of the revenue 
requirement of incremental capital investment above that 
embedded in base rates, including depreciation, property taxes 
and a return on the incremental investment.

§Commodity-related bad debt true-up
A mechanism that allows a utility to reconcile commodity-related 
bad debt to either actual commodity-related bad debt or to a 
specified commodity-related bad debt write-off percentage. For 
electricity utilities, this mechanism also includes working capital.

◊Pension/OPEB true-up
A mechanism that reconciles the actual non-capitalised costs of 
pension and OPEB and the actual amount recovered in base rates. 
The difference may be amortised and recovered over a period or 
deferred for a future rate case.

Internal control and risk factors

Disclosure controls
Working with management, including the Chief Executive and 
Finance Director, we have evaluated the effectiveness of the design 
and operation of our disclosure controls and procedures as at 
31 March 2015. Our disclosure controls and procedures are 
designed to provide reasonable assurance of achieving their 
objectives, however, the effectiveness of any system of disclosure 
controls and procedures has limitations including the possibility of 
human error and the circumvention or overriding of the controls 
and procedures.

Even effective disclosure controls and procedures provide only 
reasonable assurance of achieving their objectives. Based on the 
evaluation, the Chief Executive and Finance Director concluded 
that the disclosure controls and procedures are effective to provide 
reasonable assurance that information required to be disclosed 
in the reports that we file and submit under the Exchange Act 
is recorded, processed, summarised and reported as and 
when required and that such information is accumulated and 
communicated to our management, including the Chief Executive 
and Finance Director, as appropriate, to allow timely decisions 
regarding disclosure.

Internal control over financial reporting 
Our management, including the Chief Executive and Finance 
Director, has carried out an evaluation of our internal control over 
financial reporting pursuant to the Disclosure and Transparency 
Rules and Section 404 of the Sarbanes-Oxley Act 2002. As 
required by Section 404, management is responsible for 
establishing and maintaining an adequate system of internal control 
over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) 
under the Exchange Act). 

Our internal control over financial reporting is 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. 

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 risk that controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate.

Management evaluation of the effectiveness of the Company’s 
internal control over financial reporting was based on the revised 
Internal Control-Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway 
Commission. Based on this evaluation, management concluded 
that our internal control over financial reporting was effective as 
at 31 March 2015.

PricewaterhouseCoopers LLP, which has audited our consolidated 
financial statements for the year ended 31 March 2015, has also 
audited the effectiveness of our internal control over financial 
reporting. Their attestation report can be found on page 85.

During the year, there were no changes in our internal control over 
financial reporting that have materially affected, or are reasonably 
likely to materially affect, it.

Risk factors
Management of our risks is an important part of our internal control 
environment, as we describe on pages 38 to 41. In addition to the 
principal risks listed we face a number of inherent risks that could 
have a material adverse effect on our business, financial condition, 
results of operations and reputation, as well as the value and 
liquidity of our securities. 

Any investment decision regarding our securities and any forward-
looking statements made by us should be considered in the light 
of these risk factors and the cautionary statement set out on the 
inside back cover. An overview of the key inherent risks we face 
is provided below. 

Risk factors

Potentially harmful activities

Aspects of the work we do could potentially harm employees, 
contractors, members of the public or the environment.
Potentially hazardous activities that arise in connection with our 
business include the generation, transmission and distribution of 
electricity and the storage, transmission and distribution of gas. 

We are subject to laws and regulations in the UK and US 
governing health and safety matters to protect the public and our 
employees and contractors, who could potentially be harmed by 
these activities as well as laws and regulations relating to pollution, 
the protection of the environment, and the use and disposal of 
hazardous substances and waste materials. 

Electricity and gas utilities also typically use and generate 
hazardous and potentially hazardous products and by-products. 
In addition, there may be other aspects of our operations that are 
not currently regarded or proved to have adverse effects but could 
become so, such as the effects of electric and magnetic fields.

These expose us to costs and liabilities relating to our operations 
and properties, including those inherited from predecessor 
bodies, whether currently or formerly owned by us, and sites 
used for the disposal of our waste. 

A significant safety or environmental incident, or the failure of 
our safety processes or of our occupational health plans, as well 
as the breach of our regulatory or contractual obligations or our 
climate change targets, could materially adversely affect our 
results of operations and our reputation.

We commit significant resources and expenditure to process 
safety and to monitoring personal safety, occupational health 
and environmental performance, and to meeting our obligations 
under negotiated settlements.

The cost of future environmental remediation obligations is often 
inherently difficult to estimate and uncertainties can include the 
extent of contamination, the appropriate corrective actions and 
our share of the liability. We are increasingly subject to regulation 
in relation to climate change and are affected by requirements to 
reduce our own carbon emissions as well as to enable reduction 
in energy use by our customers.

If more onerous requirements are imposed or our ability to recover 
these costs under regulatory frameworks changes, this could 
have a material adverse impact on our business, reputation, 
results of operations and financial position.

Risk factors

Infrastructure and IT systems

We may suffer a major network failure or interruption,  
or may not be able to carry out critical operations due to the 
failure of infrastructure, data or technology or a lack of supply.
Operational performance could be materially adversely affected 
by a failure to maintain the health of our assets or networks, 
inadequate forecasting of demand, inadequate record keeping 
or control of data or failure of information systems and 
supporting technology. 

This in turn could cause us to fail to meet agreed standards 
of service, incentive and reliability targets, or be in breach of a 
licence, approval, regulatory requirement or contractual obligation. 
Even incidents that do not amount to a breach could result in 
adverse regulatory and financial consequences, as well as 
harming our reputation.

Where demand for electricity or gas exceeds supply and our 
balancing mechanisms are not able to mitigate this fully, a lack 
of supply to consumers may damage our reputation.

In addition to these risks, we may be affected by other potential 
events that are largely outside our control, such as the impact 
of weather (including as a result of climate change and major 
storms), unlawful or unintentional acts of third parties, insufficient 
or unreliable supply or force majeure. 

Law and regulation

Weather conditions can affect financial performance and severe 
weather that causes outages or damages infrastructure together 
with our actual or perceived response could materially adversely 
affect operational and potentially business performance and 
our reputation.

Malicious attack, sabotage or other intentional acts, including 
breaches of our cyber security, may also damage our assets 
(which include critical national infrastructure) or otherwise 
significantly affect corporate activities and, as a consequence, 
have a material adverse impact on our reputation, business, 
results of operations and financial condition. 

Unauthorised access to, or deliberate breaches of, our IT systems 
may also lead to manipulation of our proprietary business data 
or customer information.

Unauthorised access to private customer information may make 
us liable for a violation of data privacy regulations. Even where we 
establish business continuity controls and security against threats 
against our systems, these may not be sufficient.

Changes in law or regulation or decisions by governmental 
bodies or regulators could materially adversely affect us.
Most of our businesses are utilities or networks subject to 
regulation by governments and other authorities. Changes in 
law or regulation or regulatory policy and precedent, including 
decisions of governmental bodies or regulators, in the countries 
or states in which we operate could materially adversely affect us. 

 advancing energy technologies, whether aspects of our 
activities are contestable, the level of permitted revenues 
and dividend distributions for our businesses and in relation 
to proposed business development activities, could have a 
material adverse impact on our results of operations, cash 
flows, the financial condition of our businesses and the ability 
to develop those businesses in the future.

If we fail to engage in the energy policy debate, we may not be 
able to influence future energy policy and deliver our strategy. 

Decisions or rulings concerning, for example:

(i) 

 whether licences, approvals or agreements to operate or 
supply are granted, amended or renewed, whether consents 
for construction projects are granted in a timely manner or 
whether there has been any breach of the terms of a licence, 
approval or regulatory requirement; and

(ii)   timely recovery of incurred expenditure or obligations, the 
ability to pass through commodity costs, a decoupling of 
energy usage and revenue, and other decisions relating to the 
impact of general economic conditions on us, our markets 
and customers, implications of climate change and of

Business performance

Current and future business performance may not meet our 
expectations or those of our regulators and shareholders.
Earnings maintenance and growth from our regulated gas and 
electricity businesses will be affected by our ability to meet or 
exceed efficiency targets and service quality standards set by, 
or agreed with, our regulators. 

Following the introduction of EMR, there has been an increased 
focus (from some of our stakeholders) on the potential conflicting 
duties of our transmission and system operator roles, which may 
damage our reputation.

The remediation plans in place or being implemented to address 
control weaknesses in our US business may not operate as 
expected, as a result of which we may be unable to provide timely 
regulatory reporting, which may include the provision of financial 
statements. This could result in the imposition of regulatory fines, 
penalties and other sanctions, which could impact our operations, 
our reputation and our relationship with our regulators and 
other stakeholders.

For further information see pages 166 to 172, which explain our 
regulatory environment in detail.

If we do not meet these targets and standards, or if we do not 
implement the transformation projects we are carrying out as 
envisaged, including to our US enterprise resource planning 
systems and controls over financial reporting, or are not able 
to deliver our RIIO operating model and the US Elevate 2018 
strategy successfully, we may not achieve the expected benefits, 
our business may be materially adversely affected and our 
performance, results of operations and reputation may be 
materially harmed and we may be in breach of regulatory or 
contractual obligations.

Risk factors

Growth and business development activity

Failure to respond to external market developments and 
execute our growth strategy may negatively affect our 
performance. Conversely, new businesses or activities that 
we undertake alone or with partners may not deliver target 
outcomes and may expose us to additional operational and 
financial risk.
Failure to grow our core business sufficiently and have viable 
options for new future business over the longer term could 
negatively affect the Group’s credibility and reputation and 
jeopardise the achievement of intended financial returns. 

Business development activities and the delivery of our growth 
ambition, including acquisitions, disposals, joint ventures, 
partnering and organic investment opportunities (including 
organic investments made as a result of changes to the energy 
mix), are subject to a wide range of both external uncertainties 
(including the availability of potential investment targets and

Cost escalation

Changes in foreign currency rates, interest rates or 
commodity prices could materially impact earnings or our 
financial condition.
We have significant operations in the US and so are subject to the 
exchange rate risks normally associated with non UK operations, 
including the need to translate US assets and liabilities, and 
income and expenses, into sterling, our primary reporting currency.

In addition, our results of operations and net debt position may 
be affected because a significant proportion of our borrowings, 
derivative financial instruments and commodity contracts are

Our results of operations could be affected by inflation 
or deflation.
In our regulated UK networks, our allowed revenues are set in real 
terms and then adjusted for actual RPI inflation. There is a risk that 
inflationary impacts on our costs are higher than RPI inflation and 
are not fully compensated by this inflation adjustment to revenues. 
There is also a risk that year-on-year RPI inflation is negative with 
no corresponding decrease in costs or insufficient decrease to 
offset the impact on revenues. 

We may be required to make significant contributions to fund 
pension and other post-retirement benefits.
We participate in a number of pension schemes that together 
cover substantially all our employees. In both the UK and US, 
the principal schemes are DB schemes where the scheme assets 
are held independently of our own financial resources.

In the US, we also have other post-retirement benefit schemes. 
Estimates of the amount and timing of future funding for the UK 
and US schemes are based on actuarial assumptions and other 
factors including: the actual and projected market performance 
of the scheme assets; future long-term bond yields; average life 
expectancies; and relevant legal requirements.

attractive financing and the impact of competition for onshore 
transmission in both the UK and US), and internal uncertainties 
(including actual performance of our various existing operating 
companies and our business planning model assumptions and 
ability to integrate acquired businesses effectively). As a result, 
we may suffer unanticipated costs and liabilities and other 
unanticipated effects.

We may also be liable for the past acts, omissions or liabilities 
of companies or businesses we have acquired, which may be 
unforeseen or greater than anticipated. In the case of joint 
ventures, we may have limited control over operations and our 
joint venture partners may have interests that diverge from our own. 

The occurrence of any of these events could have a material 
adverse impact on our results of operations or financial condition, 
and could also impact our ability to enter into other transactions.

affected by changes in interest rates, commodity price indices and 
exchange rates, in particular the dollar to sterling exchange rate.

Furthermore, our cash flow may be materially affected as a result 
of settling hedging arrangements entered into to manage our 
exchange rate, interest rate and commodity price exposure, or 
by cash collateral movements relating to derivative market values, 
which also depend on the sterling exchange rate into euro and 
other currencies.

Our income under our rate plans in the US is not typically linked to 
inflation. In periods of inflation in the US, our operating costs may 
increase by more than our revenues. In both the UK and US such 
increased costs may materially adversely affect the results of 
our operations.

Actual performance of scheme assets may be affected by volatility 
in debt and equity markets. 

Changes in these assumptions or other factors may require us to 
make additional contributions to these pension schemes which, 
to the extent they are not recoverable under our price controls 
or state rate plans, could materially adversely affect the results 
of our operations and financial condition.

Risk factors

Financing and liquidity

An inability to access capital markets at commercially 
acceptable interest rates could affect how we maintain and 
grow our businesses.
Our businesses are financed through cash generated from 
our ongoing operations, bank lending facilities and the capital 
markets, particularly the long-term debt capital markets. 

Some of the debt we issue is rated by credit rating agencies 
and changes to these ratings may affect both our borrowing 
capacity and borrowing costs. In addition, restrictions imposed 
by regulators may also limit how we service the financial 
requirements of our current businesses or the financing 
of newly acquired or developing businesses.

Financial markets can be subject to periods of volatility and 
shortages of liquidity. If we were unable to access the capital 
markets or other sources of finance at competitive rates for 
a prolonged period, our cost of financing may increase, the 
discretionary and uncommitted elements of our proposed 
capital investment programme may need to be reconsidered 
and the manner in which we implement our strategy may need 
to be reassessed. 

Such events could have a material adverse impact on our 
business, results of operations and prospects.

Some of our regulatory agreements impose lower limits for 
the long-term senior unsecured debt credit ratings that certain 
companies within the Group must hold or the amount of equity 
within their capital structures.

Customers and counterparties

Customers and counterparties may not perform 
their obligations.
Our operations are exposed to the risk that customers, suppliers, 
banks and other financial institutions and others with whom 
we do business will not satisfy their obligations, which could 
materially adversely affect our financial position.

This risk is significant where our subsidiaries have concentrations 
of receivables from gas and electricity utilities and their affiliates, 
such as from our previous LIPA managed services agreement 
(MSA) and current PSEG-LI transition services agreement (TSA), 
as well as industrial customers and other purchasers, and may 
also arise where customers are unable to pay us as a result of 
increasing commodity prices or adverse economic conditions. 

Employees and others

We may fail to attract, develop and retain employees with the 
competencies, including leadership and business capabilities, 
values and behaviours required to deliver our strategy and 
vision and ensure they are engaged to act in our best interests.
Our ability to implement our strategy depends on the capabilities 
and performance of our employees and leadership at all levels of 
the business. Our ability to implement our strategy and vision may 
be negatively affected by the loss of key personnel or an inability 
to attract, integrate, engage and retain appropriately qualified

One of the principal limits requires National Grid plc to hold an 
investment grade long-term senior unsecured debt credit rating. 
In addition, some of our regulatory arrangements impose 
restrictions on the way we can operate. 

These include regulatory requirements for us to maintain 
adequate financial resources within certain parts of our operating 
businesses and may restrict the ability of National Grid plc and 
some of our subsidiaries to engage in certain transactions, 
including paying dividends, lending cash and levying charges. 

The inability to meet such requirements or the occurrence of 
any such restrictions may have a material adverse impact on 
our business and financial condition.

The remediation plans in place or being implemented to 
address control weaknesses in our US business may not 
operate as expected, as a result of which we may be unable 
to provide accurate financial information to our debt investors 
in a timely manner. 

Our debt agreements and banking facilities contain covenants, 
including those relating to the periodic and timely provision of 
financial information by the issuing entity and financial covenants, 
such as restrictions on the level of subsidiary indebtedness. 

Failure to comply with these covenants, or to obtain waivers of 
those requirements, could in some cases trigger a right, at the 
lender’s discretion, to require repayment of some of our debt and 
may restrict our ability to draw upon our facilities or access the 
capital markets.

To the extent that counterparties are contracted with for physical 
commodities (gas and electricity) and they experience events 
that impact their own ability to deliver, we may suffer supply 
interruption as described in Infrastructure and IT systems on 
page 174.

There is also a risk to us where we invest excess cash or enter 
into derivatives and other financial contracts with banks or other 
financial institutions. Banks who provide us with credit facilities 
may also fail to perform under those contracts.

personnel, or if significant disputes arise with our employees. 
As a result, there may be a material adverse effect on our 
business, financial condition, results of operations and prospects.

There is a risk that an employee or someone acting on our 
behalf may breach our internal controls or internal governance 
framework or may contravene applicable laws and regulations. 
This could have an impact on the results of our operations, 
our reputation and our relationship with our regulators and 
other stakeholders.

Additional InformationShareholder information

Articles of Association 
The following description is a summary of the material terms of 
our Articles and applicable English law. It is a summary only and 
is qualified in its entirety by reference to the Articles.

Summary
The Articles set out the Company’s internal regulations. Copies are 
available on our website and upon request. Amendments to the 
Articles have to be approved by at least 75% of those voting at a 
general meeting of the Company. Subject to company law and the 
Articles, the Directors may exercise all the powers of the Company. 
They may delegate authorities to committees and day-to-day 
management and decision-making to individual Executive 
Directors. The committee structure is set out on page 49.

General
The Company is incorporated under the name National Grid plc 
and is registered in England and Wales with registered number 
04031152. Under the Companies Act 2006, the Company’s objects 
are unrestricted.

Directors
Under the Articles, a Director must disclose any personal interest 
in a matter and may not vote in respect of that matter, subject to 
certain limited exceptions. As permitted under the Companies Act 
2006, the Articles allow non conflicted Directors of the Company 
to authorise a conflict or potential conflict for a particular matter. 
In doing so, the non conflicted Directors must act in a way they 
consider, in good faith, will be most likely to promote the success 
of the Company for the benefit of the shareholders as a whole.

The Directors (other than a Director acting in an executive capacity) 
are paid fees for their services. In total, these fees must not exceed 
£2,000,000 a year or any higher sum decided by an ordinary 
resolution at a general meeting of shareholders. In addition, 
special pay may be awarded to a Director who acts in an executive 
capacity, serves on a committee, performs services which the 
Directors consider to extend beyond the ordinary duties of a 
Director, devotes special attention to the business of National Grid, 
or goes or lives abroad on the Company’s behalf. Directors may 
also receive reimbursement for expenses properly incurred, 
and may be awarded pensions and other benefits. The 
compensation awarded to the Executive Directors is determined 
by the Remuneration Committee. Further details of Directors’ 
remuneration are set out in the Directors’ Remuneration Report 
(see pages 60 to 75).

The Directors may exercise all the powers of National Grid to 
borrow money. However, the aggregate principal amount of all 
the Group’s borrowings outstanding at any time must not exceed 
£35 billion or any other amount approved by shareholders by 
an ordinary resolution at a general meeting.

Directors can be appointed or removed by the Board or 
shareholders in a general meeting. Directors must stand for 
election at the first AGM following their appointment to the Board. 
Each Director must retire at least every three years, although they 
will be eligible for re-election. In accordance with best practice 
introduced by the UK Corporate Governance Code, all Directors 
wishing to continue in office currently offer themselves for 
re-election annually. No person is disqualified from being a 
Director or is required to vacate that office by reason of attaining 
a maximum age.

A Director is not required to hold shares in National Grid in order 
to qualify as a Director.

Rights, preferences and restrictions
(i) Dividend rights
National Grid may not pay any dividend otherwise than out of 
profits available for distribution under the Companies Act 2006 and 
other applicable provisions of English law. In addition, as a public 
company, National Grid may only make a distribution if, at the time 
of the distribution, the amount of its net assets is not less than 
the aggregate of its called up share capital and undistributable 
reserves (as defined in the Companies Act 2006) and to the extent 
that the distribution does not reduce the amount of those assets to 
less than that aggregate. Ordinary shareholders and ADS holders 
receive dividends.

Subject to these points, shareholders may, by ordinary resolution, 
declare dividends in accordance with the respective rights of the 
shareholders, but not exceeding the amount recommended by 
the Board. The Board may pay interim dividends if it considers that 
National Grid’s financial position justifies the payment. Any dividend 
or interest unclaimed for 12 years from the date when it was 
declared or became due for payment will be forfeited and revert 
to National Grid.

(ii) Voting rights
Subject to any rights or restrictions attached to any shares and to 
any other provisions of the Articles, at any general meeting on a 
show of hands, every shareholder who is present in person will 
have one vote and on a poll, every shareholder will have one vote 
for every share they hold. On a show of hands or poll, shareholders 
may cast votes either personally or by proxy. A proxy need not be 
a shareholder. Under the Articles, all substantive resolutions at a 
general meeting must be decided on a poll. Ordinary shareholders 
and ADS holders can vote at general meetings.

(iii) Liquidation rights
In a winding up, a liquidator may, in each case with the sanction 
of a special resolution passed by the shareholders and any 
other sanction required under English law, (a) divide among the 
shareholders the whole or any part of National Grid’s assets 
(whether the assets are of the same kind or not); the liquidator may, 
for this purpose, value any assets and determine how the division 
should be carried out as between shareholders or different classes 
of shareholders, or (b) transfer any part of the assets to trustees 
on trust for the benefit of the shareholders as the liquidator 
determines. In neither case will a shareholder be compelled 
to accept assets upon which there is a liability.

(iv) Restrictions
There are no restrictions on the transfer or sale of ordinary shares. 
Some of the Company’s employee share plans, details of which 
are contained in the Directors’ Remuneration Report, include 
restrictions on the transfer of shares while the shares are subject 
to the plan. Where, under an employee share plan operated by the 
Company, participants are the beneficial owners of the shares but 
not the registered owner, the voting rights may be exercised by 
the registered owner at the direction of the participant. Treasury 
shares do not attract a vote or dividends.

Variation of rights
Subject to applicable provisions of English law, the rights attached 
to any class of shares of National Grid may be varied or cancelled. 
This must be with the written consent of the holders of three 
quarters in nominal value of the issued shares of that class, or with 
the sanction of a special resolution passed at a separate meeting 
of the holders of the shares of that class.

General meetings
AGMs must be convened each year within six months of the 
Company’s accounting reference date upon 21 clear days’ 
advance written notice. Any other general meeting may be 
convened provided at least 14 clear days’ written notice is given, 
subject to annual approval of shareholders. In certain limited 
circumstances, the Company can convene a general meeting by 
shorter notice. The notice must specify, among other things, the 
nature of the business to be transacted, the place, the date and 
the time of the meeting.

Rights of non residents
There are no restrictions under National Grid’s Articles that would 
limit the rights of persons not resident in the UK to vote in relation 
to ordinary shares.

Disclosure of interests
Under the Companies Act 2006, National Grid may, by written 
notice, require a person whom it has reasonable cause to believe 
to be or to have been in the last three years interested in its shares 
to provide additional information relating to that interest. Under 
the Articles, failure to provide such information may result in a 
shareholder losing their rights to attend, vote or exercise any 
other right in relation to shareholders’ meetings.

Under the UK Disclosure and Transparency Rules, there is also an 
obligation on a person who acquires or ceases to have a notifiable 
interest in shares in National Grid to notify the Company of that fact. 
The disclosure threshold is 3% and disclosure is required each time 
the person’s direct and indirect holdings reach, exceed or fall below 
each 1% threshold thereafter.

The UK City Code on Takeovers and Mergers imposes strict 
disclosure requirements with regard to dealings in the securities 
of an offeror or offeree company, and also on their respective 
associates, during the course of an offer period. Other regulators 
in the UK, US and elsewhere may have, or assert, notification 
or approval rights over acquisitions or transfers of shares.

Depositary payments to the Company
The Depositary reimburses the Company for certain expenses 
it incurs in relation to the ADS programme. The Depositary also 
pays the standard out-of-pocket maintenance costs for the ADSs, 
which consist of the expenses for the mailing of annual and interim 
financial reports, printing and distributing dividend cheques, 
electronic filing of US federal tax information, mailing required 
tax forms, stationery, postage, facsimile and telephone calls. 
It also reimburses the Company for certain investor relationship 
programmes or special investor relations promotional activities. 
There are limits on the amount of expenses for which the 
Depositary will reimburse the Company, but the amount of 
reimbursement is not necessarily tied to the amount of fees the 
Depositary collects from investors. For the period 1 April 2014 to 
20 May 2015, the Company received a total of $2,094,871.42 in 
reimbursements from the Depositary consisting of $1,440,230.53 
and $654,640.89 received in October 2014 and January 2015 
respectively. Fees that are charged on cash dividends will be 
apportioned between the Depositary and the Company,  
see below. 

Any questions from ADS holders should be directed to The Bank 
of New York Mellon at the contact details on page 196. 

Description of securities other than equity securities: 
depositary fees and charges 
The Bank of New York Mellon, as the Depositary, collects fees, by 
deducting those fees from the amounts distributed or by selling 
a portion of distributable property, for:

•  delivery and surrender of ADSs directly from investors depositing 

shares or surrendering ADSs for the purpose of withdrawal 
or from intermediaries acting for them; and

•  making distributions to investors (including, it is expected, 

cash dividends).

The Depositary may generally refuse to provide fee attracting 
services until its fees for those services are paid.

Persons depositing or 
withdrawing shares must pay:

For

Issuance of ADSs, including issuances 
resulting from a distribution of shares 
or rights or other property; cancellation 
of ADSs for the purpose of withdrawal, 
including if the Deposit Agreement 
terminates; distribution of securities 
distributed to holders of deposited 
securities that are distributed by the 
Depositary to ADS registered holders.

Transfer and registration of shares on 
our share register to or from the name 
of the Depositary or its agent when 
they deposit or withdraw shares.

Cable, telex and facsimile 
transmissions (when expressly 
provided in the Deposit Agreement); 
converting foreign currency to dollars.

As necessary.

$5.00 per 100 ADSs  
(or portion of 100 ADSs)

Registration or transfer fees

Expenses of the Depositary

Taxes and other governmental 
charges the Depositary or the 
Custodian has to pay on any ADS  
or share underlying an ADS, for 
example, stock transfer taxes, 
stamp duty or withholding taxes

The Company’s Deposit Agreement under which the ADS are 
issued allows a fee of up to $0.05 per ADS to be charged for any 
cash distribution made to ADS holders, including cash dividends. 
ADS holders who receive cash in relation to the 2014/15 final 
dividend will be charged a fee of $0.02 per ADS by the Depositary 
prior to distribution of the cash dividend.

Events after the reporting period 
There have been no material events affecting the Company since 
the year end.

Exchange controls 
There are currently no UK laws, decrees or regulations that restrict 
the export or import of capital, including, but not limited to, foreign 
exchange control restrictions, or that affect the remittance of 
dividends, interest or other payments to non UK resident holders of 
ordinary shares except as otherwise set out in Taxation on page 182 
and except in respect of the governments of and/or certain citizens, 
residents or bodies of certain countries (described in applicable 
Bank of England Notices or European Union Council Regulations 
in force as at the date of this document).

Additional InformationOn 20 April 2015, The Capital Group of Companies, Inc. notified 
us of a holding in voting rights of 3.881%, 145,094,617 ordinary 
shares, as at 16 April 2015. 

As at 20 May 2015, no further notifications have been received.

The rights attached to ordinary shares are detailed on page 177.  
All ordinary shares carry the same voting rights.

Share capital 
The share capital of the Company consists of ordinary shares of 
1117∕43 pence nominal value each and ADSs, which represent five 
ordinary shares each.

Authority to purchase shares
Shareholder approval was given at the 2014 AGM to purchase up 
to 10% of the Company’s share capital (being 373,477,508 ordinary 
shares). The Directors intend to seek shareholder approval to 
renew this authority at this year’s AGM. 

In some circumstances, the Company may find it advantageous to 
have the authority to purchase its own shares in the market, where 
the Directors believe this would be in the interests of shareholders 
generally. The Directors believe that it is an important part of the 
financial management of the Company to have the flexibility to 
repurchase issued shares in order to manage its capital base, 
including actively managing share issuances from the operation 
of the scrip dividend scheme. It is expected that such repurchases 
will not exceed 2.5% of the issued share capital (excluding treasury 
shares) per annum. 

When purchasing shares, the Company have and will, take into 
account market conditions prevailing at the time, other investment 
and financing opportunities and the overall financial position of 
the Company.

During the year the Company purchased ordinary shares in the 
capital of the Company as part of the management of the dilutive 
effect of share issuances under the scrip dividend scheme. 

Authority to allot shares
Shareholder approval was given at the 2014 AGM to allot shares 
of up to one third of the Company’s share capital. The Directors are 
seeking this same lower level of authority this year. The Directors 
consider that the Company will have sufficient flexibility with the 
lower level of authority to respond to market developments. 
This authority is in line with investor guidelines.

The Directors currently have no intention of issuing new shares, 
or of granting rights to subscribe for or convert any security into 
shares, except in relation to, or in connection with, the operation 
and management of the Company’s scrip dividend scheme and 
the exercise of options under the Company’s share plans. No issue 
of shares will be made which would effectively alter control of the 
Company without the sanction of shareholders in general meeting.

The Company expects to actively manage the dilutive effect of 
share issuance arising from the operation of the scrip dividend 
scheme. In some circumstances, additional shares may be allotted 
to the market for this purpose under the authority provided by this 
resolution. Under these unlikely circumstances, it is expected that 
the associated allotment of new shares (or rights to subscribe for or 
convert any security into shares) will not exceed 1% of the issued 
share capital (excluding treasury shares) per year. 

Dividend waivers
The trustees of the National Grid Employees Share Trust, which 
are independent of the Company, waived the right to dividends 
paid during the year, and have agreed to waive the right to future 
dividends, in relation to the ordinary shares and American 
Depositary Receipts (ADR) held by the trust. 

Under the Company’s ADR programme, the right to dividends in 
relation to the ordinary shares underlying the ADRs was waived 
during the year by the ADR Depositary, under an arrangement 
whereby the Company pays the monies to satisfy any dividends 
separately to the Depositary for distribution to ADR holders entitled 
to the dividend. This arrangement is expected to continue for 
future dividends.

Taxation
The discussion in this section provides information about certain 
US federal income tax and UK tax consequences for US Holders 
(defined below) of owning ADSs and ordinary shares. A US Holder 
is beneficial owner of ADSs or ordinary shares that:

•   is (i) an individual citizen or resident of the United States, (ii) a 

corporation created or organised under the laws of the United 
States, any State thereof or the District of Columbia, (iii) an estate 
the income of which is subject to US federal income tax without 
regard to its source or (iv) a trust if a court within the United 
States is able to exercise primary supervision over the 
administration of the trust and one or more US persons have the 
authority to control all substantial decisions of the trust, or the 
trust has elected to be treated as a domestic trust for US federal 
income tax purposes;

•   is not resident or ordinarily resident in the UK for UK tax 

purposes; and

•   does not hold ADSs or ordinary shares in connection with the 

conduct of a business or the performance of services in the UK 
or otherwise in connection with a branch, agency or permanent 
establishment in the UK.

182

This discussion is not a comprehensive description of all the US 
federal income tax and UK tax considerations that may be relevant 
to any particular investor (including consequences under the US 
alternative minimum tax or net investment income tax) and does 
not address state, local, or other tax laws. National Grid has 
assumed that shareholders, including US Holders, are familiar 
with the tax rules applicable to investments in securities generally 
and with any special rules to which they may be subject. This 
discussion deals only with US Holders who hold ADSs or ordinary 
shares as capital assets. It does not address the tax treatment of 
investors who are subject to special rules, such as: 

•   financial institutions; 
•   insurance companies;
•   dealers in securities or currencies;
•   investors who elect mark-to-market treatment;
•   partnerships or other pass-through entities and their partners;
•   individual retirement accounts and other tax-deferred accounts;
•   tax-exempt organisations;
•   investors who own (directly or indirectly) 10% or more of our 

voting stock;

•   investors who hold ADSs or ordinary shares as a position in a 
straddle, hedging transaction or conversion transaction; and 

•   investors whose functional currency is not the US dollar.

The statements regarding US and UK tax laws and administrative 
practices set forth below are based on laws, treaties, judicial 
decisions and regulatory interpretations in effect on the date of this 
document. These laws and practices are subject to change without 
notice, potentially with retroactive effect. In addition, the statements 
set forth below are based on the representations of the Depositary 
and assume that each party to the Deposit Agreement will perform 
its obligations thereunder in accordance with its terms. 

US Holders of ADSs will be treated as the owners of the ordinary 
shares represented by those ADSs for US federal income tax 
purposes. For the purposes of the Tax Convention, the Estate Tax 
Convention and UK tax considerations, this discussion assumes 
that a US Holder of ADSs will be treated as the owner of the 
ordinary shares represented by those ADSs. HMRC has stated 
that it will continue to apply its long-standing practice of treating 
a holder of ADSs as holding the beneficial interest in the ordinary 
shares represented by the ADSs; however, we note that this is an 
area of some uncertainty and may be subject to change.

US Holders should consult their own advisors regarding the tax 
consequences of buying, owning and disposing of ADSs or 
ordinary shares in light of their particular circumstances, including 
the effect of any state, local, or other tax laws.

Taxation of dividends
The UK does not currently impose a withholding tax on dividends 
paid to US Holders.

Cash distributions paid out of our current or accumulated earnings 
and profits (as determined for US federal income tax purposes) 
generally will be taxable to a US Holder as dividend income. 
Distributions in excess of current and accumulated earnings and 
profits will be treated as a non-taxable return of capital to the extent 
of a US Holder’s basis in its ADSs or ordinary shares, as applicable, 
and thereafter as a capital gain. However, we do not maintain 
calculations of our earnings and profits in accordance with US 
federal income tax principles. US Holders should therefore assume 
that any distribution by us with respect to ADSs or ordinary shares 
will be reported as dividend income.

Additional InformationDividends received by non-corporate US Holders with respect to 
ADSs or ordinary shares will generally be taxable at the reduced 
rate applicable to long-term capital gains provided (i) either (a) we 
are eligible for the benefits of the Tax Convention or (b) ADSs or 
ordinary shares are treated as ‘readily tradable’ on an established 
securities market in the United States and (ii) we are not, for our 
taxable year during which the dividend is paid or the prior year, a 
passive foreign investment company for US federal income tax 
purposes (a PFIC), and certain other requirements are met. We (1) 
expect that our shares will be treated as ‘readily tradable’ on an 
established securities market in the United States as a result of the 
trading of ADSs on the New York Stock Exchange and (2) believe 
we are eligible for the benefits of the Tax Convention. Based on 
our audited financial statements and the nature of our business 
activities, we believe that we were not treated as a PFIC for US 
federal income tax purposes with respect to our taxable year 
ending 31 March 2015. In addition, based on our current 
expectations regarding the value and nature of our assets, 
the sources and nature of our income, and the nature of our 
business activities, we do not anticipate becoming a PFIC in 
the foreseeable future.

Dividends received by corporate US Holders with respect to ADSs 
or ordinary shares will not be eligible for the dividends received 
deduction generally allowed to corporations.

Taxation of capital gains
US Holders will not be subject to UK taxation on any capital gain 
realised on the sale or other disposition of ADSs or ordinary shares.

Provided that we are not a PFIC for any taxable year during which 
a US Holder holds their ADSs or ordinary shares, upon a sale or 
other disposition of ADSs or ordinary shares, a US Holder generally 
will recognise capital gain or loss equal to the difference between 
the US dollar value of the amount realised on the sale or other 
disposition and the US Holder’s adjusted tax basis in the ADSs 
or ordinary shares. Such capital gain or loss generally will be 
long-term capital gain or loss if the ADSs or ordinary shares 
were held for more than one year. For non-corporate US Holders, 
long-term capital gain is generally taxed at a lower rate than 
ordinary income. A US Holder’s ability to deduct capital losses 
is subject to significant limitations.

UK stamp duty and stamp duty reserve tax (SDRT)
Transfers of ordinary shares – SDRT at the rate of 0.5% of the 
amount or value of the consideration will generally be payable on 
any agreement to transfer ordinary shares that is not completed 
using a duly stamped instrument of transfer (such as a stock 
transfer form). 

Where an instrument of transfer is executed and duly stamped 
before the expiry of the six year period beginning with the date on 
which the agreement is made, the SDRT liability will be cancelled. 
If a claim is made within the specified period, any SDRT which 
has been paid will be refunded. SDRT is due whether or not the 
agreement or transfer is made or carried out in the UK and whether 
or not any party to that agreement or transfer is a UK resident. 

Purchases of ordinary shares completed using a stock transfer 
form will generally result in a UK stamp duty liability at the rate of 
0.5% (rounded up to the nearest £5) of the amount or value of the 
consideration. Paperless transfers under the CREST paperless 
settlement system will generally be liable to SDRT at the rate of 
0.5%, and not stamp duty. SDRT is generally the liability of the 
purchaser and UK stamp duty is usually paid by the purchaser 
or transferee.

Transfers of ADSs – No UK stamp duty will be payable on the 
acquisition or transfer of existing ADSs or beneficial ownership 
of ADSs, provided that any instrument of transfer or written 
agreement to transfer is executed outside the UK and remains 
at all times outside the UK. 

An agreement for the transfer of ADSs in the form of ADRs will not 
result in a SDRT liability. A charge to stamp duty or SDRT may arise 
on the transfer of ordinary shares to the Depositary or The Bank of 
New York Mellon as agent of the Depositary (the Custodian). 

The rate of stamp duty or SDRT will generally be 1.5% of the value 
of the consideration or, in some circumstances, the value of the 
ordinary shares concerned. However, there is no 1.5% SDRT 
charge on the issue of ordinary shares (or, where it is integral to 
the raising of new capital, the transfer of ordinary shares) to the 
Depositary or the Custodian. 

The Depositary will generally be liable for the stamp duty or SDRT. 
Under the terms of the Deposit Agreement, the Depositary will 
charge any tax payable by the Depositary or the Custodian (or their 
nominees) on the deposit of ordinary shares to the party to whom 
the ADSs are delivered against such deposits. If the stamp duty 
is not a multiple of £5, the duty will be rounded up to the nearest 
multiple of £5.

US information reporting and backup withholding tax
Dividend payments made to US Holders and proceeds paid from 
the sale, exchange, redemption or disposal of ADSs or ordinary 
shares to US Holders may be subject to information reporting to 
the US Internal Revenue Service (IRS). Such payments may be 
subject to backup withholding taxes unless the holder (i) is a 
corporation or other exempt recipient or (ii) provides a taxpayer 
identification number on a properly completed IRS Form W-9 
and complies with applicable certification requirements.

US Holders should consult their tax advisors about these rules 
and any other reporting obligations that may apply to the 
ownership or disposition of ADSs or ordinary shares, including 
reporting requirements related to the holding of certain foreign 
financial assets.

UK inheritance tax
An individual who is domiciled in the US for the purposes of the 
Estate Tax Convention and who is not a UK national for the 
purposes of the Estate Tax Convention will generally not be subject 
to UK inheritance tax in respect of (i) the ADSs or ordinary shares 
on the individual’s death or (ii) a gift of the ADSs or ordinary shares 
during the individual’s lifetime. This is not the case where the 
ADSs or ordinary shares are part of the business property of the 
individual’s permanent establishment in the UK or relate to a 
fixed base in the UK of an individual who performs independent 
personal services.

Special rules apply to ADSs or ordinary shares held in trust. In the 
exceptional case where the ADSs or shares are subject both to UK 
inheritance tax and to US federal gift or estate tax, the Estate Tax 
Convention generally provides for the tax paid in the UK to be 
credited against tax paid in the US.

Capital gains tax (CGT) for UK resident shareholders
You can find CGT information relating to National Grid shares 
for UK resident shareholders on our website under: Investors, 
Shareholder centre, More information and help. Share prices 
on specific dates are also available on our website.

Additional InformationNATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15Other disclosures

All-employee share plans 
The all-employee share plans allow UK- or US-based employees to 
participate in either HMRC (UK) or Internal Revenue Service (US) 
approved plans and to become shareholders in National Grid.

Sharesave
Employees resident in the UK are eligible to participate in the 
Sharesave plan. Under this plan, participants may contribute 
between £5 and £500 in total each month, for a fixed period of three 
years, five years or both. Contributions are taken from net salary.

SIP
Employees resident in the UK are eligible to participate in the SIP. 
Contributions up to £150 are deducted from participants’ gross 
salary and used to purchase ordinary shares in National Grid each 
month. The shares are placed in trust.

US Incentive Thrift Plans
Employees of National Grid’s US companies are eligible to 
participate in the Thrift Plans, which are tax-advantaged savings 
plans (commonly referred to as 401(k) plans). They are DC pension 
plans that give participants the opportunity to invest up to applicable 
federal salary limits. The federal limits for calendar year 2014 are: for 
pre-tax contributions a maximum of 50% of salary limited to $17,500 
for those under the age of 50 and $23,000 for those age 50 and 
above; for post-tax contributions, up to 15% of salary. The total 
amount of employee contributions (pre-tax and post-tax) may 
not exceed 50% of compensation and are further subject to the 
combined federal annual contribution limit of $52,000. For calendar 
year 2015, participants may invest up to the applicable federal salary 
limits: for pre-tax contributions a maximum of 50% of salary limited 
to $18,000 for those under the age of 50 and $24,000 for those age 
50 and above; for post-tax contributions up to 15% of salary. The 
total amount of employee contributions (pre-tax and post-tax) may 
not exceed 50% of compensation and are further subject to the 
combined federal annual contribution limit of $53,000.

ESPP
Employees of National Grid’s US companies are eligible to 
participate in the ESPP (commonly referred to as a 423(b) plan). 
Eligible employees have the opportunity to purchase ADSs on 
a monthly basis at a 15% discounted price. Under the plan 
employees may contribute up to 20% of base pay each year up 
to a maximum annual contribution of $18,888 to purchase ADSs 
in National Grid.

Change of control provisions 
No compensation would be paid for loss of office of Directors on 
a change of control of the Company. As at 31 March 2015, the 
Company had undrawn borrowing facilities with a number of its 
banks of £1.4 billion available to it and a further £630 million of 
drawn bank loans which, on a change of control of the Company 
following a takeover bid, may alter or terminate. All the Company’s 
share plans contain provisions relating to a change of control. 
Outstanding awards and options would normally vest and become 
exercisable on a change of control, subject to the satisfaction of 
any performance conditions at that time. In the event of a change 
of control of the Company, a number of governmental and 
regulatory consents or approvals are likely to be required arising 
from laws or regulations of the UK, US or the EU. Such consents or 
approvals may also be required for acquisitions of equity securities 
that do not amount to a change of control.

No other agreements that take effect, alter or terminate upon a 
change of control of the Company following a takeover bid are 
considered to be significant in terms of their potential impact on 
the business as a whole.

184

Code of Ethics 
In accordance with US legal requirements, the Board has adopted 
a Code of Ethics for senior financial professionals. This code is 
available on our website (where any amendments or waivers will 
also be posted). There were no amendments to, or waivers of, 
our Code of Ethics during the year.

Conflicts of interest
The Board continues to monitor and note possible conflicts of 
interest that each Director may have. The Directors are regularly 
reminded of their continuing obligations in relation to conflicts, and 
are required annually to review and confirm their external interests. 
Potential conflicts are considered and, if appropriate, authorised. 
During the year ended 31 March 2015, the Board has been 
advised by the Directors of two actual conflicts of interest and has 
authorised these conflicts in accordance with its powers as set out 
in the Articles. The Board has also considered and noted a number 
of situations in relation to which no actual conflict of interest 
was identified.

Corporate governance practices: differences from 
New York Stock Exchange (NYSE) listing standards
The Company is listed on the NYSE and is therefore required to 
disclose differences in its corporate governance practices adopted 
as a UK listed company, compared with those of a US company.

The corporate governance practices of the Company are primarily 
based on the requirements of the UK Corporate Governance Code 
(the Code) but substantially conform to those required of US 
companies listed on the NYSE. The following is a summary of the 
significant ways in which the Company’s corporate governance 
practices differ from those followed by US companies under 
Section 303A Corporate Governance Standards of the NYSE.

•  The NYSE rules and the Code apply different tests for the 

independence of Board members.

•  The NYSE rules require a separate nominating/corporate 

governance committee composed entirely of independent 
Directors. There is no requirement for a separate corporate 
governance committee in the UK. Under the Company’s corporate 
governance policies, all Directors on the Board discuss and 
decide upon governance issues and the Nominations Committee 
makes recommendations to the Board with regard to certain 
of the responsibilities of a corporate governance committee.
•  The NYSE rules require listed companies to adopt and disclose 
corporate governance guidelines. While the Company reports 
compliance with the Code in each Annual Report and Accounts, 
the UK requirements do not require the Company to adopt and 
disclose separate corporate governance guidelines.

•  The NYSE rules require a separate audit committee composed 
of at least three independent members. While the Company’s 
Audit Committee exceeds the NYSE’s minimum independent 
Non-executive Director membership requirements, it should be 
noted that the quorum for a meeting of the Audit Committee, 
of two independent Non-executive Directors, is less than the 
minimum membership requirements under the NYSE rules.
•  The NYSE rules require a compensation committee composed 

entirely of independent Directors, and prescribe criteria to 
evaluate the independence of the committee’s members and 
its ability to engage external compensation advisors. While the 
Code prescribes different independence criteria, the Non-
executive Directors on the Remuneration Committee have each 
been deemed independent by the Board under the NYSE rules. 
Although the evaluation criteria for appointment of external 
advisors differ under the Code, the Remuneration Committee is 
solely responsible for appointment, retention and termination of 
such advisors.

Additional InformationDirectors’ indemnity
The Company has arranged, in accordance with the Companies 
Act 2006 and the Articles, qualifying third-party indemnities against 
financial exposure that Directors may incur in the course of their 
professional duties. Equivalent qualifying third-party indemnities 
were, and remain, in force for the benefit of those Directors who 
stood down from the Board during the year ended 31 March 2015. 
Alongside these indemnities, the Company places Directors’ and 
Officers’ liability insurance cover for each Director.

Employees 
We negotiate with recognised unions. It is our policy to maintain 
well developed communications and consultation programmes 
and there have been no material disruptions to our operations from 
labour disputes during the past five years. National Grid believes 
that it can conduct its relationships with trade unions and 
employees in a satisfactory manner.

Human Rights 
Respect for human rights is incorporated into our employment 
practices and our values, which include respecting others and 
valuing diversity. ‘Always Doing the Right Thing’ is our guide to 
ethical business conduct – the way in which we conduct ourselves 
allows us to build trust with the people we work with. We earn this 
trust by doing things in the right way, building our reputation as an 
ethical company that our stakeholders want to do business with, 
and that our employees want to work for. Although we do not have 
a specific policy relating to human rights, our procurement policies 
integrate sustainability into the way we do business throughout our 
supply chain, so that we create value, preserve natural resources 
and respect the interests of the communities we serve and from 
which we procure goods and services. Through our Global 
Supplier Code of Conduct, we expect our suppliers to keep to all 
laws relating to their business, as well as adhere to the principles of 
the United Nations Global Compact, the United Nations Declaration 
of Human Rights and the International Labour Organization.

Political donations and expenditure
National Grid made no donations in the UK or EU during the year, 
including donations as defined for the purposes of the Political 
Parties, Elections and Referendums Act 2000. National Grid USA 
and its affiliated New York and federal political action committees 
(each, a PAC) made political donations in the US totalling $54,375 
(£34,415) during the year. National Grid USA’s affiliated New York 
PAC was funded partly by contributions from National Grid USA 
and certain of its subsidiaries and partly by voluntary employee 
contributions. National Grid USA’s affiliated federal PAC was 
funded wholly by voluntary employee contributions.

Property, plant and equipment 
This information can be found under the heading note 11 property, 
plant and equipment on page 115, note 19 Borrowings on pages 
123 and 124, Strategic Report pages 08 to 11, where we operate 
on page 165 and principal operations on pages 27 to 36.

Research and development
Expenditure on research and development during the year was 
£23 million (2013/14: £12 million; 2012/13: £15 million). Innovation 
funding throughout 2014/15 has stimulated greater investment 
across all three of our UK Regulated business areas: UK ET, UK GT 
and UK GD. Delivering benefits for our stakeholders has been at 
the forefront of each of our Innovation Projects. This has driven 
collaboration across the industry in search of new techniques to 
revolutionise the way we work. Due to the way in which we work 
with a large number of partners on new ideas, our disclosed 
research and development expenditure is lower than the overall 
contribution we make to the industry. We only disclose directly 
incurred expenditure, and not those amounts our partners incur 
working on projects with us. 

The UK ET innovation portfolio has developed to reflect the 
evolution of our strategic innovation priorities. Our activities in the 
year have focused on enhancing our capabilities in managing 
ageing assets, improving the efficiency of new build, and system 
reliability and availability. In addition NGET secured £6.9 million of 
funding to develop new approaches to frequency control. The UK 
GT innovation portfolio has developed and expanded over the past 
year to include projects on 3D modelling, virtual reality technologies 
and sustainable energy solutions. In addition, GT won £5.7 million 
of funding for industry leading work in robotics for Project GRAID 
(Gas Robotic Agile Inspection Device). Innovation in UK GD has 
focused on reduction of leakage levels and minimisation of street 
works and excavations through the use of robotics. Our customers 
have been central to our portfolio, with projects enhancing safety 
through the use of Intelligent Carbon Monoxide monitoring and 
more robust on-site fencing feet and projects improving real-time 
information for work on-site through the use of QR codes.

The US business has been working on research and development 
initiatives to improve the way we deliver gas operations, and on 
modernising the US electricity grid in Massachusetts and 
Reforming the Energy Vision (REV) in New York State. More 
information in relation to grid modernisation and REV can be found 
on page 170.

Reconciliations of adjusted profit measures

Use of adjusted profit measures
In considering the financial performance of our businesses and 
segments, we analyse each of our primary financial measures 
of operating profit, profit before tax, profit for the year attributable 
to equity shareholders and EPS into two components.

The first of these components is referred to as an adjusted profit 
measure, also known as a business performance measure. 
This is the principal measure used by management to assess 
the performance of the underlying business.

Adjusted results exclude exceptional items, remeasurements and 
stranded cost recoveries. These items are reported collectively 
as the second component of the financial measures. Note 4 on 
page 103 explains in detail the items which are excluded from our 
adjusted profit measures.

Adjusted profit measures have limitations in their usefulness 
compared with the comparable total profit measures as they 
exclude important elements of our financial performance. 
However, we believe that by presenting our financial performance 
in two components it is easier to read and interpret financial 
performance between periods, as adjusted profit measures are 
more comparable having removed the distorting effect of the 
excluded items. Those items are more clearly understood if 
separately identified and analysed.

The presentation of these two components of financial 
performance is additional to, and not a substitute for, the 
comparable total profit measures presented.

Management uses adjusted profit measures as the basis 
for monitoring financial performance and in communicating 
financial performance to investors in external presentations 
and announcements of financial results.

Internal financial reports, budgets and forecasts are primarily 
prepared on the basis of adjusted profit measures, although 
planned exceptional items, such as significant restructurings, 
are also reflected in budgets and forecasts. We separately monitor 
and disclose the excluded items as a component of our overall 
financial performance.

Additional InformationCommentary on consolidated financial statements 
for the year ended 31 March 2014

In compliance with SEC rules, we present a summarised analysis of movements in the income statement, an analysis of movements in 
adjusted operating profit by operating segment and a summarised analysis of movements in the statement of financial position for the 
year ended 31 March 2014. This should be read in conjunction with the 31 March 2015 unaudited commentary included on pages 87, 
91 and 99. 

Analysis of the income statement for the years 
ended 31 March 2014 and 31 March 2013
Revenue
Revenue for the year ended 31 March 2014 increased by 
£450 million to £14,809 million. This increase was driven by higher 
revenues in our UK ET and UK GD businesses, principally as a 
result of the new RIIO regulatory arrangements. Revenue in our 
US Regulated businesses was also higher, reflecting higher 
pass-through costs such as gas and electricity commodity costs, 
partially offset by the end of Niagara Mohawk deferral revenue 
recoveries at March 2013 and the impact of the weaker dollar.

Revenue for the year ended 31 March 2013 increased by 
£527 million to £14,359 million driven by the UK ET business, which 
increased by £300 million principally due to inflationary increases 
in allowable revenue and higher pass-through costs. The UK GD 
segment also delivered an additional £114 million primarily for 
the same reason. Finally, US Regulated revenue was £123 million 
higher due to the recovery of Niagara Mohawk deferral revenues 
and higher FERC rate bases.

Operating costs
Operating costs for the year ended 31 March 2014 of £11,074 
million were £464 million higher than the prior year. This increase 
in costs was predominantly due to increases in pass-through 
costs in our UK and US regulated businesses, together with higher 
depreciation and amortisation as a result of continued investment 
and increases in our controllable costs.

Exceptional items, remeasurements and stranded cost recoveries 
included in operating costs for the year ended 31 March 2014 were 
£39 million lower than the prior year. Net exceptional gains included 
in 2013/14 of £55 million primarily consisted of a net gain on the 
LIPA MSA transition in the US of £254 million, a gain of £16 million 
following the sale to a third party of a settlement award, 
restructuring costs of £136 million and UK gas holder demolition 
costs of £79 million. The 2013/14 results also included a gain of 
£16 million on remeasurements of commodity contracts. 

There were no major storms affecting our operations in the year 
ended 31 March 2014. In 2012/13, two major storms in the US, 
Superstorm Sandy and Storm Nemo, increased operating costs 
by £136 million.

Operating costs for the year ended 31 March 2013 of £10,610 
million were £313 million higher than the prior year. The increase in 
costs was predominantly due to increases in pass-through costs 
due to the colder winter in the US and inflationary increases in our 
controllable costs. Additional costs of £91 million were incurred 
in the stabilisation of our US enterprise resource planning system.

Exceptional items included in operating profit of £110 million in 
2012/13 consisted of restructuring costs of £87 million, less a 
gain on sale of our EnergyNorth gas business and Granite State 
electricity business in New Hampshire of £3 million. There were 
also gains of £180 million on commodity contract remeasurements.

Net finance costs
For the year ended 31 March 2014, net finance costs before 
exceptional items and remeasurements were £16 million lower than 
2012/13 at £1,108 million, mainly due to the impact of the weaker 
dollar (£17 million).

Total net finance costs for the year ended 31 March 2013 were 
slightly down compared with 2011/12 at £1,086 million, due to 
the reduction in the cost of our index-linked debt, offset by the 
cost of carrying higher debt levels and loss on disposal of 
financial instruments.

Financial remeasurements relate to net gains and losses on 
derivative financial instruments. The year ended 31 March 2014 
included a gain of £93 million (2012/13: gain of £68 million).

Tax
The 2013/14 adjusted tax charge was £38 million lower than 
2012/13 at £581 million. This was mainly due to a 1% decrease 
in the UK statutory corporation tax rate in the year and a change 
in the UK/US profit mix where higher UK profits were taxed at the 
lower UK tax rate. Our tax charge was also affected by changes 
in tax provisions in respect of prior years.

For the year ended 31 March 2013, our adjusted tax charge 
was £78 million lower than 2011/12, mainly due to changes in 
tax provisions in respect of prior years and a 2% decrease in the 
UK statutory corporation tax rate in the year, partially offset by 
increased taxes on higher taxable profits. 

Exceptional tax for 2013/14 included an exceptional deferred tax 
credit of £398 million arising from a reduction in the UK corporation 
tax rate from 23% to 21% applicable from 1 April 2014 and a further 
reduction to 20% from 1 April 2015.

A similar reduction in the UK corporation tax rate in 2012/13 from 
24% to 23% resulted in a deferred tax credit of £128 million.

Adjusted earnings and EPS
As a result of the variances described above, adjusted earnings 
for the year ended 31 March 2014 was £2,015 million. For the year 
ended 31 March 2013, adjusted earnings was £1,913 million. 

The above earnings performance translated into adjusted EPS 
growth in 2013/14 of 2.6p (5%) and 5.4p (12%) in 2012/13.

In accordance with IAS 33, all EPS and adjusted EPS amounts for 
comparative periods have been restated for shares issued via scrip 
dividends and the bonus element of the 2010 rights issue.

Analysis of the adjusted operating profit by segment 
for the year ended 31 March 2014
UK Electricity Transmission
For the year ended 31 March 2014, revenue in the UK Electricity 
Transmission segment increased by £277 million, and adjusted 
operating profit increased by £38 million.

Net regulated income after pass-through costs was £170 million 
higher, reflecting increases in allowed revenues under the new RIIO 
regulatory framework. This was partially offset by under-recoveries 
of revenue in the year of £60 million compared with over-recoveries 
of £29 million in the prior year. Regulated controllable costs were 
£27 million higher due to inflation, legal fees and one-off credits in 
the prior year. Depreciation and amortisation was £20 million higher 
reflecting the continued capital investment programme (investment 
in the year was £1,381 million). Other costs were £4 million lower 
than prior year.

UK Gas Transmission
Revenue in the UK Gas Transmission segment decreased by 
£177 million in 2013/14 to £941 million and adjusted operating profit 
fell by £114 million to £417 million.

Net regulated income after pass-through costs was £80 million 
lower, with lower permit income than prior year under the new 
RIIO arrangements. In addition, under-recoveries in the year of 
£21 million compared with over-recoveries last year of £17 million, 
gave rise to an adverse timing movement of £38 million. 
Depreciation and amortisation was £10 million higher due to 
investment, with £181 million invested in the year. Partially offsetting 
these, other operating costs were £14 million lower.

UK Gas Distribution
UK Gas Distribution revenue increased by £184 million in the year 
to £1,898 million, and adjusted operating profit increased by 
£110 million to £904 million.

Net regulated income after pass-through costs was £96 million 
higher, reflecting increases in allowed revenues under the new 
RIIO regulatory framework. Timing differences added another 
£39 million, with £29 million over-recoveries in 2013/14, compared 
with a £10 million under-recovery in the prior year. Partially 
offsetting these, regulated controllable costs were £14 million 
higher primarily due to inflation. Depreciation and amortisation 
was £10 million higher reflecting the continued capital investment 
programme (investment in the year was £480 million). Other costs 
were £1 million higher than prior year.

US Regulated
Revenue in our US Regulated businesses was £122 million higher 
at £8,040 million, and adjusted operating profit fell by £129 million 
to £1,125 million.

The weaker dollar reduced operating profit in the year by 
£38 million. Excluding the impact of foreign exchange, net 
regulated income fell by £52 million, principally due to the end of 
deferral income recoveries at Niagara Mohawk in March 2013. 
Timing differences added another £29 million profit compared with 
prior year. Regulated controllable costs increased by £89 million 
at constant currency as a result of inflation and wage increases, 
higher insurance costs post Superstorm Sandy, and cost true-ups 
identified during the implementation of the new enterprise resource 
planning system. Other operating costs (excluding major storms) 
increased by £61 million at constant currency due to the higher 
cost of non-major storm remediation, higher property taxes and 
depreciation of the new US enterprise resource planning system. 

There were no major storms affecting our operations in the year 
ended 31 March 2014. In 2012/13, two major storms in the US, 
Superstorm Sandy and Storm Nemo, reduced operating profit 
within US Regulated by £82 million at constant currency.

Our capital investment programme continued in the US, 
with a further £1,219 million invested in 2013/14.

Other activities
Revenue in Other activities increased by £58 million to £736 million 
in the year ended 31 March 2014. Adjusted operating profit was 
£120 million higher at £131 million.

There was no repeat of the major storm cost of £51 million incurred 
in our insurance captive in the prior year due to Superstorm Sandy. 
Operating profit in the French interconnector was £62 million 
higher as a result of strong auction revenues this year. In our other 
non-regulated businesses, adjusted operating profit was £7 million 
higher due to improved results in our UK metering business and 
insurance captive, partially offset by higher costs associated with 
the stabilisation of the new US enterprise resource planning system.

Capital expenditure in our Other activities was £37 million lower 
at £180 million, principally reflecting reduced capital spend on the 
new US enterprise resource planning system.

year ended 31 March 2014
Goodwill and other intangible assets
Goodwill and intangibles decreased by £354 million to £5,263 
million as at 31 March 2014. This decrease was due to foreign 
exchange movements of £472 million and software amortisation 
of £127 million, partially offset by software additions of £179 million.

Other non-current liabilities decreased by £43 million principally 
due to foreign exchange movements of £47 million.

Net debt
Net debt is the aggregate of cash and cash equivalents, current 
financial and other investments, borrowings, and derivative financial 
assets and liabilities.

The principal movements in net obligations during the year included 
a curtailment gain of £214 million following the LIPA MSA transition, 
net actuarial gains of £485 million and employer contributions of 
£596 million. Net actuarial gains included actuarial gains on plan 
liabilities of £542 million arising as a consequence of an increase in 
the UK real discount rate and the nominal discount rate in the US. 
This was partially offset by actuarial losses of £283 million arising 
from increases in life expectancy in the US. Actuarial losses/gains 
on plan assets reflects the asset allocations in the different plans. 
In both the UK and US, returns on equities were above the 
assumed rate; however, UK Government securities had negative 
returns and corporate bonds were close to nil.

Off balance sheet items
There were no significant off balance sheet items other than the 
contractual obligations shown in note 30(b) to the consolidated 
financial statements, and the commitments and contingencies 
discussed in note 27.

Through the ordinary course of our operations, we are party to 
various litigation, claims and investigations. We do not expect 
the ultimate resolution of any of these proceedings to have a 
material adverse effect on our results of operations, cash flows 
or financial position.

Property, plant and equipment
Property, plant and equipment increased by £587 million to 
£37,179 million as at 31 March 2014. This was due to capital 
expenditure of £3,262 million on the renewal and extension of our 
regulated networks, offset by foreign exchange movements of 
£1,244 million, and £1,299 million of depreciation in the year.

Investments and other non-current assets
Investments in joint ventures and associates; financial and other 
investments and other non-current assets decreased by £31 million 
to £722 million as at 31 March 2014. This was principally due to 
changes in the fair value of our US commodity contract assets and 
available-for-sale investments.

Inventories and current intangible assets, and trade and 
other receivables
Inventories and current intangible assets, and trade and other 
receivables decreased by £78 million to £3,123 million as at 
31 March 2014. This decrease was principally due to foreign 
exchange movements of £195 million, partially offset by an increase 
in trade and other receivables of £120 million mostly due to colder 
weather in the US in February and March 2014 compared with 
2013 resulting in increased billings for commodity costs and 
customer usage. 

Trade and other payables
Trade and other payables decreased by £20 million to £3,031 million 
as at 31 March 2014 due to favourable foreign exchange movements 
of £150 million, partially offset by higher payables in the UK due 
in part to changes in payment terms with new Gas Distribution 
strategic partners and increased activity on the Western Link project.

Current tax liabilities
Current tax liabilities decreased by £63 million to £168 million at 
31 March 2014. This was primarily due to higher tax payments 
made in 2013/14 although these were partially offset by a larger 
current tax charge.

Deferred tax liabilities
Deferred tax liabilities increased by £5 million to £4,082 million 
as at 31 March 2014. This was primarily due to the impact of the 
£172 million deferred tax charge on actuarial gains (a £179 million 
tax credit in 2012/13) being offset by the impact of the reduction 
in the UK statutory tax rate for future periods, foreign exchange 
movements and the reduction in prior year charges.

Provisions and other non-current liabilities
Provisions (both current and non-current) and other non-current 
liabilities decreased by £158 million to £3,486 million as at 
31 March 2014.

Total provisions decreased by £115 million to £1,645 million as at 
31 March 2014. The underlying movements included additions of 
£230 million primarily relating to a provision for the demolition of 
certain gas holders in the UK of £79 million, restructuring provisions 
of £86 million and other provisions of £42 million, more than 
offset by foreign exchange movements of £112 million and 
utilisation of £288 million in relation to all classes of provisions.

Companies Act 2006. The Directors’ Report, comprising pages 06 
to 75 and 164 to 191, has been drawn up in accordance with the 
requirements of English law, and liability in respect thereof is also 
governed by English law. In particular, the liability of the Directors 
for these reports is solely to National Grid.

This document contains certain statements that are neither 
reported financial results nor other historical information. These 
statements are forward-looking statements within the meaning of 
Section 27A of the Securities Act of 1933, as amended, and 
Section 21E of the Securities Exchange Act of 1934, as amended. 
These statements include information with respect to our financial 
condition, our results of operations and businesses, strategy, plans 
and objectives. Words such as ‘anticipates’, ‘expects’, ‘should’, 
‘intends’, ‘plans’, ‘believes’, ‘outlook’, ‘seeks’, ‘estimates’, ‘targets’, 
‘may’, ‘will’, ‘continue’, ‘project’ and similar expressions, as well as 
statements in the future tense, identify forward-looking statements. 
These forward-looking statements are not guarantees of our  
future performance and are subject to assumptions, risks and 
uncertainties that could cause actual future results to differ 
materially from those expressed in or implied by such forward-
looking statements. Many of these assumptions, risks and 
uncertainties relate to factors that are beyond our ability to control 
or estimate precisely, such as changes in laws or regulations, 
announcements from and decisions by governmental bodies or 
regulators (including the timeliness of consents for construction 
projects); the timing of construction and delivery by third parties  
of new generation projects requiring connection; breaches of, or 
changes in, environmental, climate change and health and safety 
laws or regulations, including breaches or other incidents arising 
from the potentially harmful nature of our activities; network failure 
or interruption, the inability to carry out critical non network 

operations and damage to infrastructure, due to adverse weather 
conditions including the impact of major storms as well as the 
results of climate change, due to counterparties being unable  
to deliver physical commodities, or due to the failure of or 
unauthorised access to or deliberate breaches of our IT systems 
and supporting technology; performance against regulatory targets 
and standards and against our peers with the aim of delivering 
stakeholder expectations regarding costs and efficiency savings, 
including those related to investment programmes and internal 
transformation and remediation plans; and customers and 
counterparties (including financial institutions) failing to perform 
their obligations to the Company. Other factors that could cause 
actual results to differ materially from those described in this 
document include fluctuations in exchange rates, interest rates  
and commodity price indices; restrictions and conditions (including 
filing requirements) in our borrowing and debt arrangements, 
funding costs and access to financing; regulatory requirements for 
us to maintain financial resources in certain parts of our business 
and restrictions on some subsidiaries’ transactions such as paying 
dividends, lending or levying charges; inflation or deflation; the 
delayed timing of recoveries and payments in our regulated 
businesses and whether aspects of our activities are contestable; 
the funding requirements and performance of our pension 
schemes and other post-retirement benefit schemes; the failure to 
attract, train or retain employees with the necessary competencies, 
including leadership skills, and any significant disputes arising  
with our employees or the breach of laws or regulations by our 
employees; and the failure to respond to market developments, 
including competition for onshore transmission, and grow our 
business to deliver our strategy, as well as incorrect or unforeseen 
assumptions or conclusions (including unanticipated costs and 
liabilities) relating to business development activity, including 
assumptions in connection with joint ventures.

For further details regarding these and other assumptions, risks 
and uncertainties that may affect National Grid, please read the 
Strategic Report and the Risk factors on pages 173 and 176 of this 
document. In addition, new factors emerge from time to time and 
we cannot assess the potential impact of any such factor on our 
activities or the extent to which any factor, or combination of 
factors, may cause actual future results to differ materially from 
those contained in any forward-looking statement. Except as  
may be required by law or regulation, the Company undertakes  
no obligation to update any of its forward-looking statements, 
which speak only as of the date of this document.
