Launching Two Strong Companies

7478_NarrC6.indd 1

3/10/16   11:21 AM

Chairman’s Letter

The macro-economic events of 2015 were like 
a bracing, cold storm for our industry, driving 
the S&P Metals & Mining Index down 51%. 
The prices of aluminum dropped 28% and of 
alumina by 43%. As Alcoa’s common stock 
traded like an aluminum fi nancial derivative 
with a 95% correlation to the London Metal 
Exchange price, the decline in metal price pulled 
the share price substantially down despite our 
attractive Value-Add portfolio.

The good news—that feeling of relief after 
stepping out of the cold into a warm room—
is that in 2015 we completed our portfolio 
transformation. We exited high-cost commodity 
assets and invested in multi-material 
acquisitions and modernization projects in 
markets where Alcoa’s innovation strength 
will give us tremendous profi table growth 
opportunities. We are now in position to unlock 
the intrinsic value of our powerful portfolio by 
separating Alcoa into two independent publicly-
traded companies. Upon the separation, which 
is expected to be completed in the second 
half of 2016, the Upstream Company and the 
Value-Add Company will be launched, each 
with unique value propositions and distinctly 
different risk profi les and goals. 

For our future Upstream Company, during 
2015, we made our upstream portfolio more 
competitive by moving it farther down the cost 
curve. We announced additional curtailments 
and closures of high-cost facilities, for a total 
reduction since 2007 of 48% of our smelting 
operating capacity and 36% of our refi ning 
capacity. The upstream businesses also made 
$532 million of productivity improvements, 
renegotiated long-term energy contracts 
and brought on line the world’s lowest-cost 
aluminum smelting and alumina refi ning 
complex in Saudi Arabia. We re-focused the 

upstream portfolio around fi ve free-standing 
business units—the world’s largest low-cost 
Bauxite miner, the largest fi rst-quartile Alumina 
refi nery business, a second-quartile Aluminum 
smelter producer with a global footprint, a value-
add Cast Products business, and a portfolio of 
valuable Energy assets. The restructuring better 
positioned the future Upstream Company, which 
will retain the Alcoa brand name, to optimize 
profi ts in down cycles and deliver strong returns 
in peak times, creating an ideal investment for 
commodity and value investors. 

For our future Value-Add Company, the 
portfolio actions, innovation successes and 
improvements to the cost base within our 
downstream and midstream businesses in 
2015 will make the Value-Add Company 
extremely attractive to growth investors, 
particularly those with an aerospace and 
automotive investment portfolio. The value-add 
businesses made $616 million in productivity 
improvements, achieved signifi cant savings 
from synergies with recent acquisitions, and 
divested a high-cost plant in Russia. During 
2015, most of our Value-Add portfolio achieved 
major share gains in their respective markets. 

With virtually every aircraft, spacecraft and 
jet engine fl ying today containing Alcoa’s 
high-performance materials, we’ve made 
important investments to solidify our leading 
position in the fast-growing aerospace industry. 
Completing the integration of three multi-
material acquisitions in 2015, we expanded 
our penetration of the most advanced aircraft 
engine and airframe segments where our 
innovation strength creates a powerful 
competitive edge for Alcoa. We also made plant 
upgrades that enable Alcoa to achieve attractive 
profi tability levels and produce aluminum-
lithium and other high performance material

components for next generation aircraft and 
jet engines. These actions resulted in market 
share gain from our principal aerospace 
materials competitor and winning $10 billion 
of aerospace contracts in the twelve months 
ending in January 2016. 

With the strong organic and inorganic growth 
in our aerospace businesses within our 
Engineered Products and Solutions group, 
we moved our Wheel and Transportation 
Products and our Building and Construction 
businesses to form a new Transportation 
and Construction Solutions group. This 
enables a better focus on maximizing our 
profi table growth opportunities in all business 
segments. Through a strong focus on 
innovation and creating customer value, we 
have been widening our lead in the wheels 
industry. Alcoa is driving the switch from 
steel to aluminum wheels by bringing down 
operating costs, increasing load capacity, 
reducing greenhouse gas emissions and 
creating a much better wheel appearance. 
For fl eet operators and truckers, that is a 
hard-to-beat value package. In our building 
and construction business, Alcoa’s innovative 
architectural systems are helping builders 
meet E.U. and U.S. commitments for zero 
energy buildings and are driving our business’ 
expansion into China and the Middle East. 

With environmental regulations also impacting 
the automotive industry, Alcoa has become a 
major driver (and benefi ciary) of one of the 
most signifi cant disruptions in the industry’s 
history—the aluminum-intensive vehicle. 
The commercial success of Ford’s F-150 is 
leading a major shift to aluminum by other 
automotive manufacturers seeking to lessen 
weight and increase fuel effi ciency and 
payload. To meet the demand for automotive 

aluminum sheet, which is expected to ramp 
up to an eleven-fold increase by 2025, 
we’ve modernized our plants in Tennessee 
and Davenport, Iowa, with state-of-the-art 
aluminum sheet production equipment. We 
also signed a joint development agreement 
with Ford for our Micromill™ process that 
dramatically improves the formability and 
strength of aluminum sheet while reducing 
production time from 20 days to 20 minutes. 
With twelve global carmakers in discussions 
with Alcoa to evaluate and qualify Alcoa 
Micromill® products to improve their 
automotive value chain, the commercialization 
of this revolutionary technology is well 
underway. We are structuring the Micromill 
commercialization as a software business, 
where Alcoa will grant various levels of 
licenses and receive fees from the 
respective users. 

We are at the forefront of the technology 
revolution in manufacturing. In addition to 
the Micromill, we are applying disruptive 
technologies across the additive manufacturing 
spectrum to increase Alcoa’s profi tability and 
speed of innovation. In 2015, we accelerated 
our 3D printing initiative, enabling us to 
upgrade Alcoa plants with the next generation 
of 3D printing capability. The project also 
creates a commercial opportunity to produce 
proprietary and highly sophisticated metal 
powders made from titanium, nickel and 
aluminum alloys for the high-growth metals-
based additive manufacturing market; these 
powders are the “intelligent ink” needed for 
3D metal printing.

While applying disruptive technologies and 
strategies and working toward the separation, 
we have been careful to retain the core Values 
that have been Alcoa’s bedrock for 127 years. 

Combined with Alcoa’s business success, 
those enduring Values have been instrumental 
in Alcoa being chosen for the fi fth consecutive 
year as Fortune’s “World’s Most Admired 
Metals Company.” After our company 
separates, those Values will continue to guide 
our businesses into the future. 

When we announced the separation of 
Alcoa in September 2015, we established 
a Separation Project Offi ce to manage the 
many details required to launch our two 
new companies so that our businesses can 
stay focused and undistracted on delivering 
their 2016 plans. The project offi ce is 
also identifying and managing signifi cant 
cost savings prior to the separation and 
coordinating the identifi cation of the teams 
that will lead the two new companies. Our 
leaders and employees are stepping up to this 
momentous opportunity with the enthusiasm, 
energy and engagement that we have seen 
from previous generations of Alcoans at other 
pivotal moments in Alcoa’s proud history. 

On behalf of the Alcoa Board of Directors, 
I thank you for your support during a very 
eventful 2015. We are committed to maintain 
a strong focus on shareholder value in 2016 
and to ensure the two new companies are 
well prepared to build on that commitment as 
they defi ne their bright futures. I am excited 
and proud to have the opportunity to deliver 
on that future for our shareholders, our 
customers and employees.

To strengthen the Company, Alcoa announced business 
improvement programs across its portfolios: the Value-Add 
and Upstream businesses will deliver $650 million and $600 
million, respectively, in productivity and margin improvement 
in 2016. This includes implementation of an overhead reduction 

program across the Company, of which $100 million in benefi ts is 
expected to be realized in 2016, and $225 million over two years. 
In 2015, Alcoa generated $1.2 billion in productivity savings, which 
exceeded a $900 million annual target.

Alcoa also managed return-seeking capital of $602 million 
against a $750 million annual target; controlled sustaining capital 
expenditures of $605 million against a $725 million annual target; 
and attained a debt-to-adjusted EBITDA ratio of 2.80, slightly above 
the target range (2.25 to 2.75) as a result of an unfavorable impact 
related to the mid-year acquisition of RTI International Metals.

Additionally, Alcoa’s cash from operations totaled $1.6 billion, which 
drove free cash fl ow of $402 million. As a result, Alcoa fi nished the 
year with cash on hand of $1.9 billion.

In 2015, Alcoa continued to make organic and inorganic 
investments in support of growth within the aerospace and 
automotive end markets. Including inorganic investments, average 
days working capital in fourth quarter 2015 increased 15 days 
compared to the fourth quarter of 2014. We continue to focus 
on reducing days working capital as we work to integrate the 
acquisitions.

$2.0 billion, up 5 percent over 2014.

Global Rolled Products reported ATOI of $244 million in 2015. 
The segment realized a year-over-year 15 percent increase in 
adjusted EBITDA per metric ton, refl ecting a shift to a higher-
margin product mix. This segment continued to benefi t from 
the historic shift to aluminum-intensive vehicles; in 2015, 
automotive sheet shipments doubled from 2014. 

Engineered Products and Solutions reported ATOI of $595 
million in 2015 and adjusted EBITDA of $1.1 billion, up 
9 percent from 2014. Revenue for this segment also climbed 

27 percent year-over-year. In 2015, Alcoa secured aerospace 
contracts valued at approximately $9 billion, double the 
amount in 2014, as recent aerospace growth investments 
delivered value. 

Transportation and Construction Solutions reported ATOI of 
$166 million in 2015. It also delivered a solid 2015 adjusted 
EBITDA margin of 14.4 percent.

Upstream Portfolio

The Upstream business, comprised of the Alumina and Primary Metals segments, remained profi table 
in 2015 despite lower alumina and aluminum prices. In 2015, the Upstream business reported revenue 
of $11.2 billion, ATOI of $901 million and adjusted EBITDA of $2.0 billion. 

Despite a 43 percent drop in alumina prices in 2015, the 
Alumina segment remained resilient and generated revenue 
of $5.1 billion, ATOI of $746 million and adjusted EBITDA per 
metric ton of $88. Primary Metals also reported a profi table 
2015 despite a 28 percent drop in aluminum prices. The 
segment reported revenue of $7.8 billion, ATOI of $155 
million and adjusted EBITDA per metric ton of $201. 

Alcoa’s continuing aggressive portfolio actions will remove 
approximately 25 percent of operating smelting capacity and 

approximately 20 percent of operating refi ning capacity by 
mid-2016. At that time, Alcoa globally will have 2.1 million 
metric tons of operating smelting capacity and 12.3 million 
metric tons of operating refi ning capacity remaining.

As a result, the Company is on target to meet its 2016 goals 
of moving to the 38th percentile on the global aluminum cost 
curve and 21st percentile on the global alumina cost curve.

From Transformation to Separation 

2015 was another pivotal year for Alcoa. We continued to grow our midstream 

and downstream businesses and further repositioned our upstream portfolio. 

That transformation will culminate with management’s plan to separate Alcoa 

into two independent, publicly-traded companies: a globally competitive Upstream 

Company and an innovation and technology-driven Value-Add Company. The former 

will comprise fi ve strong business units that today make up Global Primary Products: 

Bauxite, Alumina, Aluminum, Cast Products and Energy. The latter will include 

Global Rolled Products, Engineered Products and Solutions, and Transportation and 

Construction Solutions. These two leading-edge businesses, each with distinct and 

compelling opportunities, are positioned to seize the future.

The Value-Add Business
A lightweight multi-material, innovation leader 

Alcoa’s Value-Add business is a leading provider and 
premier innovator of high-performance multi-material 
products and solutions. Sixty seven percent of Value-Add’s 
2015 third-party revenue was derived from the aerospace, 
commercial transportation, building and construction, 
automotive and industrial gas turbines end markets. As it 
prepares to be a standalone company, the Value-Add business 
will continue leveraging signifi cant customer synergies, 
technology, talent and procurement across its midstream and 
downstream portfolios, positioning itself for further profi table 
growth in these fast-growing end markets.

A premier provider of Aerospace products 

By building our aerospace business, we advanced our 
transformation and in 2015, 38 percent of Value-Add 
third-party revenue came from the aerospace market. 
Our sheet, plate, structures and multi-material fasteners 
cover airplanes from nose to tail and our airfoils, rings 
and disks power jet engines. 

To broaden our reach in engines for large commercial 
aircraft, Alcoa completed the expansions of cutting-edge 
jet engine facilities in Hampton, Virginia and La Porte, Indiana. 
The La Porte facility enables production of nearly 60 percent 
larger structural parts to meet growing demand from aerospace 
engine manufacturers. Alcoa will use the advanced 
manufacturing capabilities of its facilities, including La Porte, 
to fulfi ll a contract signed with GE Aviation in 2015 valued at 
more than $1.5 billion. Alcoa will supply advanced nickel-
based superalloy, titanium and aluminum components for 
a broad range of GE Aviation engine programs.

In addition to growing by organic means, Alcoa also grew 
inorganically, acquiring RTI International Metals (RTI), a global 
leader in titanium and specialty metal products and services 
for the commercial aerospace, defense, energy and medical 
device end markets. With RTI, we broadened our reach into 
titanium—the world’s fastest-growing aerospace metal—
and added advanced technologies and materials capabilities 
for greater innovation power in aerospace and beyond. 
Alcoa also completed the acquisition of TITAL to establish 
titanium casting capabilities in Europe, enhance customer 
relationships in the region, and expand our aluminum 
casting capabilities.

using a variety of materials, including 
titanium, stainless steel and nickel-based 
superalloys, which improve fatigue 
life, enable lightning strike protection, 
and enhance wear and reusability on 
conventional and composite aircraft. 
Alcoa signed its largest-ever contract 
with Airbus worth approximately $1 billion 
for high-tech, multi-material aerospace 
fastening systems. Alcoa’s fasteners fl y on 
every Airbus platform, including new, high-
growth platforms such as the A350 XWB.

highly specialized segment of jet engine 
forgings that require isothermal forging 
technology. Isothermally forged parts 
are increasingly required in jet engines 
that use elevated turbine temperatures 
to maximize power output, drive fuel 
effi ciency and reduce emissions. The 
state-of-the art Savannah, Georgia facility 
includes a 19,500-ton isothermal press, 
shown here.

2.  Alcoa announced two multi-year 

agreements with Boeing worth more than 
$2.5 billion, including Alcoa’s largest-ever

In aerospace and beyond, 3D printing enables faster, multi-
material proto-typing, tooling and production. Prototyping 
advances speed to market, reducing new part cycle time by 
more than 50 percent. To meet growing demand for additive 
manufacturing, Alcoa is investing to strengthen our existing 
intellectual property in multi-material 3D printing and building 
on capabilities gained through RTI. The Company announced 
a $60 million expansion of the world’s largest light metals 
research center—the Alcoa Technical Center. It will include 
a state-of-the-art additive manufacturing center focused on 
feedstock materials— building on over 100 years of metal 
powder production history—processes, product design and 
qualifi cation. Demonstrating this integrated strategy, the 
Company unveiled its Ampliforge™ process, a technique 
combining advanced materials, designs and additive and 
traditional manufacturing processes. These activities build on 
20 years of additive manufacturing expertise with capabilities 
in California, Georgia, Michigan, Pennsylvania and Texas. 

1.  Alcoa secured a multi-year contract 
valued at $1.1 billion with Lockheed 
Martin for the F-35 Joint Strike Fighter 
that draws on new titanium capabilities 
gained through the RTI acquisition. The 
Joint Strike Fighter soars with all the 
Alcoa aerospace technology shown on 
the graphic.

2.  In early 2016, Alcoa announced an 
aerospace supply deal with Boeing 
that draws on our new aluminum-
lithium capabilities and our 2014 
Firth Rixson acquisition. Firth Rixson 
increased the Company’s offerings 
made of nickel-based superalloys, 
titanium, stainless steel and 
advanced aluminum alloys. With 
Firth Rixson, Alcoa holds the number 
one global position in jet engine 
rolled rings.

3.  Alcoa will support GE Aviation’s 

advanced jet engine programs as 
part of a more than $1.5 billion 
contract. Alcoa will employ advanced 
manufacturing capabilities to produce 
the parts across several facilities 
including LaPorte, Indiana; Whitehall, 
Michigan; Hampton, Virginia; Dover, 
New Jersey; Wichita Falls, Texas; 
Winsted, Connecticut in the United 
States; Dives, France; and Laval, 
Canada.

Accelerating profi tability with Automotive and 
Commercial Transportation 

Through investments and innovation in automotive, such 
as rolling mill capacity expansions and the commercialization 
of breakthrough Micromill technology, our automotive 
business continued to be at the forefront of capturing demand 
for aluminum-intensive vehicles. As a result, our automotive 
and brazing sheet revenues are expected to increase 2.4 
times from 2014 to $1.8 billion in 2018. 

In 2015, we completed our automotive expansion in Alcoa, 
Tennessee four months early to meet strong demand for 
aluminum vehicles. The new plant is the Company’s second 
major North American automotive expansion backed by 
long-term customer contracts. In the fi rst half of 2016, we 
will ramp up our Texarkana, Texas casthouse, idled since 
2009, to meet demand for aluminum slab for the automotive 
industry. The aluminum slab that will be cast at Texarkana 
will be turned into aluminum sheet at our expanded 
automotive facility in Davenport, Iowa and our rolling mill 
in Lancaster, Pennsylvania.

In 2015, Ford Motor Company selected Micromill material 
to be used for its 2016 Ford F-150 truck, making it the fi rst 
automaker to use Alcoa’s advanced automotive aluminum 
commercially. Micromill material is 40 percent more formable 
than today’s automotive aluminum—creating more design-
friendly aluminum. Alcoa and Ford are also collaborating 
to produce next-generation automotive aluminum alloys. 
The joint development agreement between Alcoa and Ford 
will further expand the existing suite of automotive alloys 
produced by Micromill technology for use on Ford vehicles. 

6.  By replacing its steel body with 
military-grade aluminum sheet, 
Ford reduced the weight of the new 
F-150 by more than 700 pounds. 
It offers customers signifi cant fuel 
economy, heavier payload, improved 
handling and greater ruggedness.

Pillar World Excellence Award for 
achieving excellence in key areas, 
including quality, cost, performance 
and delivery. Alcoa Chairman and 
CEO Klaus Kleinfeld accepted the

To drive revenue from licensing Alcoa’s intellectual property 
and technology associated with manufacturing Micromill 
products, Alcoa established a new Micromill Products and 
Services (MPS) business unit. The unit will provide services 
like training and technical support as well as generate product 
sales from our San Antonio Works facility in Texas starting 
with automotive sheet in North America and expanding into 
other market sectors and regions. By the end of 2015, Alcoa 
had secured Micromill qualifi cation agreements with 12 major 
automotive customers on three continents. In addition to the 
MPS unit, Alcoa has midstream business units focused on 
Aerospace and Automotive Products; Brazing, Commercial 
Transportation and Industrial Products; and Global Packaging.

1.  Dura-Bright® EVO wheels are lighter, 

stronger than steel and greenhouse gas-
saving. They also happen to be the most 
attractive wheels on the market. This 
combination led to the Malaysia’s Sultan 
of Johor getting Alcoa’s patented Dura-
Bright EVO wheels for his customized 
Mack Truck, the most expensive (and 
luxurious) of its kind.

12

In 2015, Alcoa also formed a new downstream business 
segment, Transportation and Construction Solutions, 
comprising Alcoa Wheel and Transportation Products, 
Alcoa Building and Construction Systems and Latin America 
Extrusions. Each business will build on existing market 
leadership positions and continue their expansion into 
emerging markets.

To capture growing demand for our lightweight, durable, 
low-maintenance aluminum commercial transportation 
wheels in Europe, Alcoa expanded its manufacturing plant 
in Hungary, doubling capacity to produce Dura-Bright® EVO 
that is 10 times more corrosion-resistant than the previous 
generation Dura-Bright® XBR, and easy to clean and maintain.

Replacing steel with aluminum reduces the overall weight 
of the vehicle, which significantly reduces greenhouse gas 
emissions associated with global warming. In 2015, Alcoa, 
in collaboration with Metalsa, a global supplier of light and 
commercial vehicle and chassis structures, introduced a 
lightweight, all-aluminum commercial truck frame at the 
Mid-America Trucking show in Louisville, Kentucky. Still in 
development, the lighter weight frame reduces truck weight 
by over 40 percent compared to steel frames, saving nearly 
900 pounds per vehicle, increasing fuel effi ciency and 
payload. The aluminum frame also offers superior corrosion 
resistance compared to steel, prolonging the vehicle’s life 
span. (See truck graphic 2)

Building for the future

Alcoa holds the number one market position in North American 
commercial architectural systems, is well established in 
Europe, and is focused on growing in emerging markets. 
We have a broad portfolio offering of products and systems 
that can serve the needs of all types of projects—from the 
smallest to the truly monumental. 

With the global demand for green building solutions 
increasing, Alcoa developed new aluminum components 
and designs that enhance energy effi ciency, reduce carbon 
emissions and help achieve green building standards. We are 
also positioned to benefi t from urbanization that will require 
more multi-family buildings and commercial fl oor space.

The Upstream Business
A cost competitive industry leader

In 2015, Alcoa took decisive action through closures, 
curtailments and productivity improvements to continue 
to create a globally competitive Upstream portfolio positioned 
to succeed through market cycles. We transitioned from 
a regional operating structure to fi ve separate business 
units focused on Bauxite, Alumina, Aluminum, Cast Products 
and Energy. As the Upstream business prepares to become 
a standalone company, we took signifi cant steps to position 
each business unit for greater effi ciency, profi tability and 
value-creation. By reshaping our portfolio, we’ve made our 
Upstream business more resilient against market volatility 
and developed new opportunities from which to extract value 
for the years ahead.

An enviable Bauxite position 

We are the world’s largest bauxite miner holding an enviable 
fi rst quartile cost curve position. We have a strong presence 
located next to major markets, with ownership of, or an 
interest in, eight mines globally, including the Huntly mine in 
Australia, the second largest in the world. With proximity to 
owned refi nery operations, our mining reserves and resources 
provide a consistent supply of bauxite. In 2015, we took steps 
to build a third-party bauxite business, including sending our 
fi rst shipment from our Juruti, Brazil mine to Europe. We also 
worked with potential new customers who are testing bauxite 
samples, and we anticipate trial shipments in 2016.

World’s most attractive Alumina portfolio

Alcoa holds the most attractive alumina portfolio in the world 
with a fi rst quartile cost curve position. We worked diligently 
to further strengthen the portfolio in 2015, and as part of a 
refi ning capacity review, we made decisions to curtail 3.5 
million metric tons of uncompetitive refi ning capacity. We also 
targeted energy improvements to further drive performance, 
converting our San Ciprian refi nery in Spain from fuel oil 
to natural gas, yielding approximately $20 per metric ton 
savings. As a result, we lowered our position on the global 
alumina cost curve to the 23rd percentile in 2015 from 
the 25th percentile in 2014, with a goal to reach the 21st 
percentile by the end of 2016. 

With nine refi neries on fi ve continents, including the world’s 
biggest alumina source—the Pinjarra refi nery in Western 
Australia—our operations are well placed to access growth 
markets in Asia, the Middle East and Latin America.

Positioned to benefi t from strong 
Aluminum demand

Global aluminum demand is expected to double between 
2010 and 2020 and so far this decade demand is tracking 
ahead of this projection. As a global aluminum producer with 
a second quartile cost curve portfolio, Alcoa is well-positioned 
to meet that robust demand. 

Through aggressive portfolio actions, Alcoa will remove 
approximately 25 percent of operating smelting capacity 
by mid-2016. Once completed, Alcoa globally will have 
2.1 million metric tons of operating smelting capacity. 
As a result of Alcoa’s decisive actions, the Company has 
dropped eight points on the global aluminum cost curve 
since 2010 to the 43rd percentile, and is targeting the 
38th percentile by the end of 2016. We achieved these 
gains through our continued focus on the elements we 
can control—reshaping our portfolio, making process 
improvements through productivity and innovation and 
investing in low-cost capacity. For example, through our 
joint venture with Ma’aden in Saudi Arabia, we’ve created 
the world’s lowest-cost smelter. The smelter in 2015 
reached production at full capacity of 740,000 metric tons.

market in 2010 by introducing 
the Alumina Price Index (API) to 
sell smelter-grade alumina based 
on alumina market fundamentals 
rather than linked to London Metal 
Exchange aluminum pricing. In 2015, 
75 percent of Alcoa’s total third-party 
smelter-grade alumina shipments 
were based on API/spot market 
pricing. That percentage is projected 
to grow to approximately 85 percent 
in 2016.

Unrivalled Cast Products network

Substantial Energy assets

Alcoa has an unrivalled network of 17 casthouses globally. 
We’ve steadily grown our cast products business by offering 
differentiated, value-add aluminum products that are cast into 
specifi c shapes to meet the needs of customers. Shapes include 
value-add slab and billet products for the automotive and 
extrusion market. Our Upstream value-add portfolio provides 
profi ts throughout the market cycle and from 2010 to 2015, our 
casting business produced $1.5 billion in incremental margins. 

Our value-add specialty foundry alloys continued to create 
value for customers and captured demand in key markets, 
such as the automotive sector. In 2015, we introduced 
EZCAST™, VERSACAST®, SUPRACAST™, and EVERCAST™—
advanced alloys with improved thermal performance and 
erosion resistance. These highly-engineered alloys provide value 
for customers and have already qualifi ed with top tier original 
equipment manufacturers. Trials are underway with more 
planned in 2016. 

Alcoa’s substantial energy assets increase operational 
fl exibility for our energy requirements while also enabling 
the business to profi t from market cyclicality. Maintaining 
cost discipline, we supply in-house energy requirements 
at the lowest possible cost and also sell power to external 
customers. Approximately 70 percent of Alcoa-generated 
power is sold externally, driving signifi cant earnings. 
Additionally, we also acquire energy for our operations.
In 2015, Alcoa of Australia Limited secured a new 12-year 
gas supply agreement (starting in 2020) to power its alumina 
refi neries in Western Australia. Combined with a number 
of smaller agreements, it now has secured approximately 
75 percent of its annual Western Australia natural gas 
requirement, replacing existing long-term contracts, 
which expire at the end of the decade.

One of the world’s largest refi neries, 
Pinjarra is part of Alcoa’s fi rst-class 
asset base with capacity of 
4.2 million metric tons per year.

2.   Value-add cast products have 
grown from 57 percent of total 
primary aluminum shipments in 
2010 to 67 percent in 2015, and 
is expected to reach 74 percent 
in 2016. Coils of aluminum rod 
in our Fjarðaál, Iceland casthouse 
await shipment.

Since 2008, Global Primary Products has generated 
$4.4 billion in productivity savings by identifying 
ideas to improve how we operate. One idea included 
the use of iPads at our Baie-Comeau smelting 
facility in Quebec, Canada. In the past, all the data 
at the smelter was collected in a centralized control 
room and a technician would inform pot operators 
when something in the pots needed adjusting. An 
employee had the idea of providing iPads to teams 
on the fl oor so they could see the changes in a pot 
real-time. An important enabler was getting the 
wireless to work in the potline under heavy magnetic 
fi elds. As a result of using iPads, operators are able 
to react more quickly when pots need adjustments. 
The quicker reaction time is saving real dollars, 
and in 2015, this idea saved Alcoa approximately 
$1 million at the Baie-Comeau plant. The process 
change has also been introduced at our smelting 
facility in Deschambault, Quebec and is being 
evaluated for use at other smelters.

Our Alcoa Values

Our Alcoa Values center on Integrity, Respect, Innovation, Excellence and Environment, 
Health and Safety. We live our Values every day, everywhere for the benefi t of our customers, 
investors, employees, communities, and partners.

ETHICS AND COMPLIANCE
The Ethics and Compliance Program continues to focus on anti-
corruption, trade compliance and adherence with all relevant U.S. 
and international laws and regulations. In 2015, Alcoa further 
strengthened and updated its Anti-Corruption Program’s policies 
and procedures by implementing an automated Anti-Corruption 
Management System for Alcoa’s intermediary due diligence 
process and the review of gifts, hospitality, and travel requests. 
Ethics and Compliance, working with our Integrity Champion 
Network and businesses, conducted a global anti-corruption risk 
assessment of Alcoa’s non-U.S. locations and functional areas. 
We also welcomed new members to our Integrity Champion 
Network, which is comprised of high-potential employees 
appointed by their organizations to raise ethics and compliance 
awareness, promote a speak-up culture and provide advice on 
ethics and compliance matters. All Alcoa employees received 
Code of Conduct training, reinforcing Alcoa’s Values and our 
commitment to advancing with integrity.

ALCOA FOUNDATION
During 2015, Alcoa Foundation contributed more than $22 million 
to Alcoa communities for programs in education and environmental 
sustainability that are vitally important to the Company. To reinforce 
its community grants, the Foundation guided the enthusiastic 
involvement of employee volunteers donating their energies and 
expertise to local organizations, including 80,000 volunteer hours 
during our annual Month of Service. The Foundation’s work in the 
communities of newly acquired plants helped to introduce our new 
colleagues to the Alcoa Values. Where Alcoa closed plants or had 
emergencies, such as the Ebola outbreak in Guinea, Foundation 
grants helped to ease the hardship experienced by the local 
communities. To ensure continued support to our communities and 
signature programs after the planned separation of the Company, 
a second foundation is being created.

SAFETY
Our world-class safety culture values human life above all else. 
All Alcoa locations have implemented Human Performance, an 
approach that focuses on anticipating and recognizing the potential 
for error and taking action to prevent errors from occurring. In 
2015, we improved our safety performance reducing our DART 
(Days Away, Restricted and Transfer) rate by 1.9 percent. Those 
efforts were overshadowed as four Alcoans and one contractor 
died from workplace injuries at Alcoa sites. These painful incidents 
have driven us to intensify our fatality prevention efforts. We 
know we can operate fatality-free. Between 2012 and 2014, we 
achieved 811 consecutive days without a fatality. As Alcoa plans to 
separate into two strong, industry-leading companies, the safety 
and well-being of our employees will remain a top priority.

SUSTAINABILITY
Alcoa is working toward a low-carbon future, with a goal to 
deliver a net positive impact on the environment. We improved 
our footprint in 2015, reducing absolute greenhouse gas (GHG) 
emissions by 5.5 million metric tons since 2014. We also 
undertook a new initiative to demonstrate the GHG avoidance 
impacts of our products, which are enabling customers to help 
de-carbonize the world. Alcoa was among the fi rst companies 
to sign the White House’s American Business Act on Climate 
Pledge, pledging by 2025 to reduce absolute U.S. GHG emissions 
by 50 percent and to demonstrate a net reduction of GHG 
emissions through the use of our products equal to three times 
the emissions created in their production. Alcoa also joined 
the Aluminum Stewardship Initiative to defi ne the fi rst global 
sustainable aluminum standard.

Overview

Alcoa is a global leader in lightweight metals engineering and manufacturing. Alcoa’s innovative, multi-material
products, which include aluminum, titanium, and nickel, are used worldwide in aerospace, automotive, commercial
transportation, packaging, building and construction, oil and gas, defense, consumer electronics, and industrial
applications.

1

Alcoa is also the world leader in the production and management of primary aluminum, fabricated aluminum, and
alumina combined, through its active participation in all major aspects of the industry: technology, mining, refining,
smelting, fabricating, and recycling. Aluminum is a commodity that is traded on the London Metal Exchange (LME)
and priced daily. Sales of primary aluminum and alumina represent approximately 40% of Alcoa’s revenues. The price
of aluminum influences the operating results of Alcoa.

Alcoa is a global company operating in 30 countries. Based upon the country where the point of sale occurred, the
United States and Europe generated 55% and 26%, respectively, of Alcoa’s sales in 2015. In addition, Alcoa has
investments and operating activities in, among others, Australia, Brazil, China, Guinea, Iceland, Russia, and Saudi
Arabia. Governmental policies, laws and regulations, and other economic factors, including inflation and fluctuations
in foreign currency exchange rates and interest rates, affect the results of operations in these countries.

Alcoa’s operations consist of five worldwide reportable segments: Alumina, Primary Metals, Global Rolled Products,
Engineered Products and Solutions, and Transportation and Construction Solutions.

The following tables and related discussion of the Company’s Bauxite Interests, Alumina Refining and Primary
Aluminum Facilities and Capacities, Global Rolled Products, Engineered Products and Solutions and Transportation
and Construction Solutions provide additional description of Alcoa’s businesses. The Alumina segment primarily
consists of a series of affiliated operating entities referred to as Alcoa World Alumina and Chemicals (AWAC). Alcoa
owns 60% and Alumina Limited owns 40% of these individual entities. For more information on AWAC, see Exhibit
Nos. 10(a) through 10(f)(1) to this report.

Proposed Separation Transaction

On September 28, 2015, Alcoa announced that its Board of Directors approved a plan to separate into two independent,
publicly-traded companies. One company will comprise the Alumina and Primary Metals segments and the other
company will comprise the Global Rolled Products, Engineered Products and Solutions, and Transportation and
Construction Solutions segments. Alcoa is targeting to complete the separation in the second half of 2016. The

2

transaction is subject to a number of conditions, including, but not limited to, final approval by Alcoa’s Board of
Directors, receipt of a favorable opinion of legal counsel with respect to the tax-free nature of the transaction for U.S.
federal income tax purposes, completed financing, and the effectiveness of a Form 10 registration statement to be filed
with the U.S. Securities and Exchange Commission. Upon completion of the separation, Alcoa shareholders will own
all of the outstanding shares of both companies. Alcoa may, at any time and for any reason until the proposed
transaction is complete, abandon the separation plan or modify or change its terms.

Bauxite Interests

This Bauxite Interests section explains the Company’s interests in various bauxite mines throughout the world. Bauxite
is one of the Company’s basic raw materials and is also a product sold into the third-party marketplace. This section
provides mine description and reserve and annual production figures in respect of the Company’s interests.

Aluminum is one of the most abundant elements in the earth’s crust. Aluminum metal is produced by smelting
alumina. Alumina is produced primarily from refining bauxite. Bauxite contains various aluminum hydroxide minerals,
the most important of which are gibbsite and boehmite. Alcoa processes most of the bauxite that it mines into alumina.
The Company obtains bauxite from its own resources and from those belonging to the AWAC enterprise, located in the
countries listed in the table below, as well as pursuant to both long-term and short-term contracts and mining leases.
Tons of bauxite are reported as bone dry metric tons (bdmt) unless otherwise stated. See the glossary of bauxite mining
related terms at the end of this section.

During 2015, mines operated by Alcoa (owned by Alcoa and AWAC) produced 38.3 million bdmt and separately
mines operated by third parties (with Alcoa and AWAC equity interests) produced 7.0 million bdmt on a proportional
equity basis for a total bauxite production of 45.3 million bdmt.

Based on the terms of its bauxite supply contracts, AWAC bauxite purchases from Mineração Rio do Norte S.A.
(MRN) and Compagnie des Bauxites de Guinée (CBG) differ from its proportional equity in those mines. Therefore
during 2015, AWAC had access to 47.8 million bdmt of production from its portfolio of mines.

During 2015, AWAC sold 2.0 million bdmt of bauxite to third parties and purchased 1.1 million bdmt from third
parties. The bauxite delivered to Alcoa and AWAC refineries amounted to 46.8 million bdmt during 2015.

The Company is growing its third-party bauxite sales business. During the third quarter of 2015, Alcoa received
permission from the Government of Western Australia to export trial shipments from its Western Australia mines.

The Company has access to large bauxite deposit areas with mining rights that extend in most cases more than 20 years
from the date of this report. For purposes of evaluating the amount of bauxite that will be available to supply as
feedstock to its refineries, the Company considers both estimates of bauxite resources as well as calculated bauxite
reserves. Bauxite resources represent deposits for which tonnage, densities, shape, physical characteristics, grade and
mineral content can be estimated with a reasonable level of confidence based on the amount of exploration sampling
and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits,
workings and drill holes. Bauxite reserves represent the economically mineable part of resource deposits, and include
diluting materials and allowances for losses, which may occur when the material is mined. Appropriate assessments
and studies have been carried out to define the reserves, and include consideration of and modification by realistically
assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. Alcoa
employs a conventional approach (including additional drilling with successive tightening of the drill grid) with
customized techniques to define and characterize its various bauxite deposit types allowing Alcoa to confidently
establish the extent of its bauxite resources and their ultimate conversion to reserves.

The table below only includes the amount of proven and probable reserves controlled by the Company. While the level
of reserves may appear low in relation to annual production levels, they are consistent with historical levels of reserves
for the Company’s mining locations. Given the Company’s extensive bauxite resources, the abundant supply of bauxite

3

globally and the length of the Company’s rights to bauxite, it is not cost-effective to invest the significant funds and
efforts necessary to establish bauxite reserves that reflect the total size of the bauxite resources available to the
Company. Rather, bauxite resources are upgraded annually to reserves as needed by the location. Detailed assessments
are progressively undertaken within a proposed mining area and mine activity is then planned to achieve a uniform
quality in the supply of blended feedstock to the relevant refinery. Alcoa believes its present sources of bauxite on a
global basis are sufficient to meet the forecasted requirements of its alumina refining operations for the foreseeable
future.

Bauxite Resource Development Guidelines

Alcoa has developed best practice guidelines for bauxite reserve and resource classification at its operating bauxite
mines. Alcoa’s reserves are declared in accordance with Alcoa’s internal guidelines as administered by the Alcoa Ore
Reserves Committee (AORC). The reported ore reserves set forth in the table below are those that Alcoa estimates
could be extracted economically with current technology and in current market conditions. Alcoa does not use a price
for bauxite, alumina, or aluminum to determine its bauxite reserves. The primary criteria for determining bauxite
reserves are the feed specifications required by the customer alumina refinery. In addition to these specifications, a
number of modifying factors have been applied to differentiate bauxite reserves from other mineralized material. Alcoa
mining locations have annual in-fill drilling programs designed to progressively upgrade the reserve and resource
classification of their bauxite.

This table shows only the AWAC and/or Alcoa share (proportion) of reserve and annual production tonnage.

This entity is part of the AWAC group of companies and is owned 60% by Alcoa and 40% by Alumina Limited.

Alumínio is owned 100% by Alcoa.

Brazilian mineral legislation does not establish the duration of mining concessions. The concession remains in force
until the exhaustion of the deposit. The Company estimates that (i) the concessions at Poços de Caldas will last at least
until 2020, (ii) the concessions at Trombetas will last until 2046 and (iii) the concessions at Juruti will last until 2100.
Depending, however, on actual and future needs, the rate at which the deposits are exploited and government approval is
obtained, the concessions may be extended to (or expire at) a later (or an earlier) date.

Alcoa World Alumina LLC (AWA LLC) owns 100% of N.V. Alcoa Minerals of Suriname (AMS). Suralco and AMS
are parts of the AWAC group of companies which are owned 60% by Alcoa and 40% by Alumina Limited.

At the end of 2015, AWAC’s bauxite mineral and mining rights remained valid until 2033. The AWAC mines in
Suriname were curtailed in the fourth quarter of 2015. There are no plans for AWAC to restart these mines and there are
no reserves to declare.

Alumínio holds an 8.58% total interest, AWA Brasil holds a 4.62% total interest and AWA LLC holds a 5% total
interest in MRN. MRN is jointly owned with affiliates of Rio Tinto Alcan Inc., Companhia Brasileira de Alumínio,
Companhia Vale do Rio Doce, BHP Billiton Plc (BHP Billiton) and Norsk Hydro. Alumínio, AWA Brasil, and AWA
LLC purchase bauxite from MRN under long-term supply contracts.

AWA LLC owns a 45% interest in Halco (Mining), Inc. (Halco). Halco owns 100% of Boké Investment Company, a
Delaware company, which owns 51% of CBG. The Guinean Government owns 49% of CBG, which has the exclusive
right through 2038 to develop and mine bauxite in certain areas within an approximately 2939 square kilometer
concession in northwestern Guinea.

AWA LLC and Alu˜mina Española, S.A. have bauxite purchase contracts with CBG that expire in 2033. Before that
expiration date, AWA LLC and Alu˜mina Española, S.A. expect to negotiate extensions of their contracts as CBG will
have concession rights until 2038. The CBG concession can be renewed beyond 2038 by agreement of the Government
of Guinea and CBG should more time be required to commercialize the remaining economic bauxite within the
concession.

Qualifying statements relating to the table above:

Australia—Darling Range Mines: Huntly and Willowdale are the two AWAC active mines in the Darling Range of
Western Australia. The mineral lease issued by the State of Western Australia to AofA is known as ML1SA and its
term extends to 2024. The lease can be renewed for an additional twenty-one year period to 2045. The declared
reserves are as for December 31, 2015. The amount of reserves reflects the total AWAC share. Additional resources are
routinely upgraded by additional exploration and development drilling to reserve status. The Huntly and Willowdale
mines supply bauxite to three local AWAC alumina refineries.

Brazil—Poços de Caldas: Declared reserves are as for December 31, 2015. Tonnage is total Alcoa share. Additional
resources are being upgraded to reserves as needed.

Brazil—Juruti RN101, RN102, RN103, RN104, #34: Declared reserves are as for December 31, 2015. All reserves
are on Capiranga Plateau. Declared reserves are total AWAC share. Declared reserve tonnages and the annual
production tonnage are washed product tonnages. The Juruti mine’s operating license is periodically renewed.

Suriname—Suralco: The AWAC mines in Suriname were curtailed in the fourth quarter of 2015. AWAC has no plans
to restart these mines and there are no reserves to declare.

Brazil—Trombetas-MRN: Declared reserves have been estimated by MRN as for December 31, 2015. The CP
Report for December 31, 2015 reserves is expected to be issued on or about February 29, 2016. Declared and annual
production tonnages reflect the total for Alumínio and AWAC shares (18.2%). Declared tonnages are washed product
tonnages.

Guinea—Boké-CBG: Declared reserves are based on export quality bauxite and have been estimated by CBG as for

tonnages reflect only the AWAC share of CBG’s reserves. Annual production tonnage is reported based on AWAC’s
22.95% share. Declared reserves quality is reported based on total alumina (TAl2 O3) and total silica (TSiO2) because
CBG export bauxite is sold on this basis. Additional resources are being routinely drilled and modeled to upgrade to
reserves as needed.

Kingdom of Saudi Arabia—Al Ba’itha: The Al Ba’itha Mine began production during 2014 and production was
increased in 2015. Declared reserves are as for December 31, 2015. The proven reserves have been decremented for

Kingdom of Saudi Arabia Joint Venture

In December 2009, Alcoa and Saudi Arabian Mining Company (Ma’aden) entered into a joint venture to develop a
fully integrated aluminum complex in the Kingdom of Saudi Arabia. In its initial phases, the complex includes a
bauxite mine with an initial capacity of 4 million bdmt per year; an alumina refinery with an initial capacity of
1.8 million mt per year (mtpy); an aluminum smelter with an initial capacity of ingot, slab and billet of 740,000 mtpy;
and a rolling mill with initial capacity of 380,000 mtpy. The mill will produce a variety of sheet products.

The refinery, smelter and rolling mill are located within the Ras Al Khair industrial zone on the east coast of the
Kingdom of Saudi Arabia.

The smelter and refinery are fully operational. The mine construction was completed in the second quarter of 2015 and
ramp up of operations is proceeding as planned.

Total capital investment is expected to be approximately $10.8 billion (SAR 40.5 billion). Ma’aden owns a 74.9%
interest in the joint venture. Alcoa owns a 25.1% interest in the smelter and rolling mill, with AWAC holding a 25.1%
interest in the mine and refinery. For additional information regarding the joint venture, see the Equity Investments
section of Note I to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary

The Point Comfort alumina refinery will be fully curtailed (see below).

As of December 31, 2015, Alcoa had approximately 2,801,000 mtpy of idle capacity against total Alcoa Consolidated
Capacity of 17,271,000 mtpy.

In March 2015, the Company initiated a 12-month review of 2,800,000 mtpy in refining capacity for possible
curtailment (partial or full), permanent closure or divestiture. This review is part of the Company’s target to lower
Alcoa’s refining operations on the global alumina cost curve to the 21st percentile (currently 23rd) by the end of 2016.
As part of this review, in March 2015, the Company decided to curtail 443,000 mtpy (one digester) of capacity at the
Suralco refinery; this action was completed by the end of April 2015.

Additionally, in September, the Company decided to curtail the remaining capacity (887,000 mtpy—two digesters) at
Suralco; the Company completed it by the end of November 2015 (877,000 mtpy of capacity at Suralco had previously
been curtailed). The Company is currently in discussions with the Suriname government to determine the best long-
term solution for Suralco due to limited bauxite reserves and the absence of a long-term energy alternative.

During 2015, Alcoa undertook curtailment of the remaining 2,010,000 mtpy of capacity at the Point Comfort, Texas
refinery (295,000 mtpy had previously been curtailed). This action is expected to be completed by the end of June 2016
(375,000 mtpy was completed by the end of December 2015).

As noted above, Alcoa and Ma’aden have developed an alumina refinery in the Kingdom of Saudi Arabia. Initial
capacity of the refinery is 1.8 million mtpy. The refinery produced approximately 1.0 million mt in 2015. For
additional information regarding the joint venture, see the Equity Investments section of Note I to the Consolidated
Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data).

In November 2005, AWA LLC and Rio Tinto Alcan Inc. (RTA) signed a Basic Agreement with the Government of
Guinea that sets forth the framework for development of a 1.5 million mtpy alumina refinery in Guinea. In 2006, the

11

Basic Agreement was approved by the Guinean National Assembly and was promulgated into law. The Basic
Agreement was originally set to expire in November 2008, but was extended several times, most recently to November
2015. Alcoa completed a pre-feasibility study in 2008, further pre-feasibility work in 2012, and concluded its
evaluation of the project in 2015. AWA LLC and RTA agreed that current market conditions are unable to support the
development of the project as originally conceived and the Basic Agreement expired in November 2015.

In September 2006, Alcoa received environmental approval from the Government of Western Australia for expansion
of the Wagerup alumina refinery to a maximum capacity of 4.7 million mtpy, a potential increase of over 2 million
mtpy. This approval had a term of five years and included environmental conditions that must be satisfied before Alcoa
could seek construction approval for the project. The project was suspended in November 2008 due to global economic
conditions and the unavailability of a secure long-term energy supply in Western Australia. These constraints continue
and as such the project remains under suspension. In May 2012, the Government of Western Australia granted Alcoa a
5 year extension of the original environmental approval. In 2015, Alcoa applied for a further five year extension. The
extension has not yet been granted and there has been no additional work done on the project.

In 2015, Alcoa and Vietnam National Coal-Minerals Industries Group began discussions regarding potential
cooperation to improve the operational and technical performance of the Tan Rai Refinery which started up in 2014. In
January 2016, the parties entered into a non-disclosure agreement to support and further the development of this
potential cooperation. The parties continue to discuss a Memorandum of Understanding (MOU).

The Rockdale smelter has been fully curtailed since the end of 2008.

The Intalco smelter has had approximately 49,000 mtpy of idle capacity. In November 2015, the Company announced
that it would idle the remaining 230,000 mtpy capacity by the end of the first quarter of 2016. In January 2016, Alcoa
announced that it will delay this further curtailment of the smelter until the end of the second quarter of 2016 (see
below).

The Wenatchee smelter has had approximately 41,000 mtpy of idle capacity. The Company idled the remaining 143,000
mtpy of capacity by the end of December 2015.

As of December 31, 2015, Alcoa had approximately 778,000 mtpy of idle capacity against total Alcoa Consolidated
Capacity of 3,401,000 mtpy.

In March 2015, the Company initiated a 12-month review of 500,000 mtpy of smelting capacity for possible
curtailment (partial or full), permanent closure or divestiture. This review is part of the Company’s target to lower
Alcoa’s smelting operations on the global aluminum cost curve to the 38th percentile (currently 43rd) by 2016. As part
of this review, in March 2015, Alcoa decided to curtail the remaining capacity (74,000 mtpy) at the Alumar smelter;
this action was completed in April 2015.

Separate from the smelting capacity review described above, in June 2015, Alcoa decided to permanently close the
Poços de Caldas smelter (96,000 mtpy) in Brazil effective immediately. The Poços de Caldas smelter had been
temporarily idle since May 2014 due to challenging global market conditions for primary aluminum and higher
operating costs, which made the smelter uncompetitive. The decision to permanently close the Poços de Caldas smelter
was based on the fact that these underlying conditions had not improved. As a result, the Poços de Caldas smelter was
removed from the table above.

In November 2015, Alcoa announced that it would curtail 503,000 mtpy of aluminum smelting capacity amid
prevailing market conditions by idling capacity at the Massena West (130,000 mtpy), Intalco (230,000 mtpy) and
Wenatchee (143,000 mtpy) smelters. The curtailment of the remaining capacity at Wenatchee was completed by the
end of December 2015 and the curtailment of the remaining capacity at Intalco was expected to be completed by the
end of March 2016. The casthouses at Massena West and Intalco will continue to operate. Later in November 2015, the
Company announced that it had entered into a three-and-a-half year agreement with New York State to increase the
competitiveness of the Massena West smelter. As a result, the Massena West smelter will continue to operate.

In January 2016, the Company announced it will delay the curtailment (230,000 mtpy) of its Intalco smelter in
Ferndale, Washington until the end of the second quarter of 2016. Recent decreases in energy and raw material costs
have made it more cost effective in the near term to keep the smelter operating.

13

In January 2016, Alcoa announced that it will permanently close its 269,000 mtpy Warrick Operations smelter in
Evansville, Indiana by the end of the first quarter of 2016. The rolling mill and power plant at Warrick Operations will
continue to operate.

As noted above, Alcoa and Ma’aden have developed an aluminum smelter in the Kingdom of Saudi Arabia. The
smelter has an initial nameplate capacity of 740,000 mtpy. Since mid-2014, the smelter has been operating at full
capacity and it produced 757,833 mt in 2015.

In 2014, Alcoa and the Brunei Economic Development Board agreed to extend for four years an existing MOU to
enable more detailed studies into the feasibility of establishing a modern, gas-powered aluminum smelter in Brunei
Darussalam to follow a period of strategic assessment of global market conditions.

In 2007, Alcoa and the Greenland Government entered into an MOU regarding cooperation on a feasibility study for an
aluminum smelter with a 360,000 mtpy capacity in Greenland. The MOU also encompasses a hydroelectric power
system and related infrastructure improvements, including a port. Due to unfavorable global market conditions for
primary aluminum, Alcoa and the Greenland Government entered into negotiations in 2015 to address, among other
subjects, formalizing an extension of estimated dates for Alcoa to achieve certain of its undertakings under the MOU,
and providing the Greenland Government latitude to develop hydro resources throughout Greenland. Negotiations
between the parties are anticipated to complete in 2016.

Global Rolled Products

The Company’s Global Rolled Products segment represents Alcoa’s midstream operations. For a discussion of this
segment’s business, see “Results of Operations—Segment Information” in Part II, Item 7. (Management’s Discussion
and Analysis of Financial Condition and Results of Operations) and Note Q to the Consolidated Financial
Statements—Segment and Geographic Area Information in Part II, Item 8. (Financial Statements and Supplementary
Data).

In March 2015, Alcoa sold its Russia-based aluminum mill in Belaya Kalitva, Alcoa Metallurg Rus, to a subsidiary of
Stupino Titanium Co.

In September 2015, Alcoa announced the completion of an expansion at its Tennessee facility dedicated to supplying
aluminum sheet to the automotive industry. The Tennessee plant will provide aluminum sheet to automakers such as
Ford Motor Company, Fiat Chrysler Automobiles and General Motors. The expansion created approximately 200 full-
time jobs.

In 2014, Alcoa announced a $190 million investment at its Davenport Works facility to expand its product offerings in
the aerospace and industrial markets through the installation of technology that will enhance the performance of thick
aluminum and aluminum-lithium plate for use in various applications such as wing ribs and fuselage frames for the
aerospace market. Construction on this project began in 2015, with first customer production expected in 2017.

In October 2015, Alcoa entered into an agreement with the Danieli Group, a global supplier of plants and equipment to
the metals industry, to license and commercialize its Micromill technology. Under the agreement, Alcoa licenses the
patented technology to Danieli that will manufacture and sell Micromill equipment to mill operators that will also be
licensed by Alcoa. The Alcoa-patented Micromill process produces metal with a microstructure that is distinct from the
microstructure obtained from conventional rolling, allowing the production of an aluminum alloy for automotive
applications that has 40 percent greater formability and 30 percent greater strength than the incumbent aluminum used
today while meeting stringent automotive surface quality requirements. Additionally, automotive parts made with
Micromill material will be twice as formable and at least 30 percent lighter than parts made from high strength steel.
The Micromill will enable the next generation of automotive aluminum products, and equip Alcoa to capture growing
automotive demand.

14

Also in 2014, Alcoa announced a $40 million investment in its Itapissuma, Brazil rolling mill to increase production of
specialty foils for aseptic and flexible packages. Initial work for the expansion is underway and commissioning is
expected to begin in 2016.

As noted above, Alcoa and Saudi Arabian Mining Company (Ma’aden) entered into a joint venture to develop a fully
integrated aluminum complex in the Kingdom of Saudi Arabia. It includes among other things the Ma’aden Rolling
Company, which owns the rolling mill that has capacity to produce 380,000 mtpy and is 74 acres under roof.

The Texarkana rolling mill facility has been idle since September 2009 due to a continued weak outlook in common
alloy markets. In September 2015, the Company announced that it is restarting its Texarkana casthouse to meet demand
for aluminum slab for the automotive industry. The aluminum slab that will be cast at Texarkana will be turned into
aluminum sheet at Alcoa’s recently expanded automotive facility in Davenport, Iowa and its rolling mill in Lancaster,
Pennsylvania.

Engineered Products and Solutions

This segment represents a portion of Alcoa’s downstream operations. For a discussion of this segment’s business, see
“Results of Operations—Segment Information” in Part II, Item 7. (Management’s Discussion and Analysis of Financial
Condition and Results of Operations) and Note Q to the Consolidated Financial Statements—Segment and Geographic
Area Information in Part II, Item 8. (Financial Statements and Supplementary Data). In the third quarter 2015, Alcoa
realigned its downstream portfolio into two segments (Engineered Products and Solutions and Transportation and
Construction Solutions). Following the realignment, Engineered Products and Solutions consists of: Alcoa Titanium &
Engineered Products; Alcoa Fastening Systems & Rings; Alcoa Forgings and Extrusions; and Alcoa Power and
Propulsion.

On March 3, 2015, Alcoa completed its acquisition of TITAL, a privately held company based in Germany. TITAL is a
leader in titanium and aluminum structural castings for aircraft engines and airframes. In addition, TITAL is a leader in
process technology.

In June 2015, Alcoa announced that it is investing $22 million in Hot Isotopic Pressing technology at its facility in
Whitehall, Michigan. The investment will enable Alcoa to capture growing demand for advanced titanium, nickel and
additive manufactured parts for the world’s bestselling engines. Alcoa expects that the new technology will be ready
for product qualification in 2016.

On July 23, 2015, Alcoa completed the acquisition of RTI International Metals, Inc. (RTI), a global supplier of
titanium and specialty metal products and services for commercial aerospace, defense, energy and medical device
markets. Following the acquisition, RTI was renamed Alcoa Titanium & Engineered Products.

Also in October 2015, Alcoa officially opened its expanded jet engines part facility in La Porte, Indiana. The $100
million expansion of the Indiana facility enables Alcoa to manufacture single piece structural parts that are 60 percent
larger than those already produced in La Porte.

In 2014, Alcoa commenced an expansion of its Hampton, Virginia facility to create the capability to employ a new
process technology that improves jet engine blades. The expansion was completed in fourth quarter 2015. The
Hampton facility includes technology that cuts the weight of the Company’s highest-volume jet engine blades by 20
percent and significantly improves aerodynamic performance.

Alcoa and VSMPO-AVISMA Corporation signed a cooperation agreement in October 2013, which allowed the
companies to meet growing demand for high-end titanium and aluminum products for aircraft manufacturers
worldwide. The new joint venture will focus on manufacturing high-end aerospace products, such as landing gear and
forged wing components, at Alcoa’s plant in Samara, Russia. The definitive Shareholders’ Agreement was executed by
the parties on July 16, 2014, and the deal is expected to close in the second quarter of 2016. The facility is now
operational.

Unless otherwise noted, facilities with ownership described as “Alcoa (100%)” are owned by the Company.

Leased property or partially leased property.

The operating results of this facility are reported in the Global Rolled Products segment.

Transportation and Construction Solutions

The Company’s Transportation and Construction Solutions segment represents a portion of Alcoa’s downstream
operations. For a discussion of this segment’s business, see “Results of Operations—Segment Information” in Part II,
Item 7. (Management’s Discussion and Analysis of Financial Condition and Results of Operations) and Note Q to the
Consolidated Financial Statements—Segment and Geographic Area Information in Part II, Item 8. (Financial
Statements and Supplementary Data). As part of its realignment of the value-add portfolio and creation of this new
segment, the Company also moved the Latin American soft alloy extrusions business to Transportation and
Construction Solutions.

In January 2015, Alcoa opened its expanded wheels manufacturing plant in Hungary, doubling Alcoa’s capacity to
produce its Dura-Bright® EVO surface-treated wheels compared with 2014 production levels. The $13 million
expansion is expected to create 35 new jobs in Hungary once the facility reaches full capacity.

Alcoa Wheel and Transportation Products has vertically integrated by building a new aluminum casthouse in Mexico
for a total cost of $22 million to convert the scrap generated throughout the Mexico wheels flowpaths into ingot. While
the first ingot was cast in November 2014, the run rate production was achieved in March 2015.

Explanatory Note: Certain aluminum produced by Alcoa also includes alloying materials. Because of the number of
different types of elements that can be used to produce Alcoa’s various alloys, providing a range of such elements
would not be meaningful. With the exception of a very small number of internally used products, Alcoa produces its
alloys in adherence to an Aluminum Association standard. The Aluminum Association, of which Alcoa is an active
member, uses a specific designation system to identify alloy types. In general, each alloy type has a major alloying
element other than aluminum but will also have other constituents as well, but of lesser amounts.

Energy

Employing the Bayer Process, Alcoa refines alumina from bauxite ore. Alcoa then produces aluminum from the
alumina by an electrolytic process requiring substantial amounts of electric power. Energy accounts for approximately
19% of the Company’s total alumina refining production costs. Electric power accounts for approximately 23% of the
Company’s primary aluminum production costs. Alcoa generates approximately 14% of the power used at its smelters
worldwide and generally purchases the remainder under long-term arrangements. The paragraphs below summarize the
sources of power and natural gas for Alcoa’s smelters and refineries.

North America – Electricity

The Deschambault, Baie Comeau, and Bécancour smelters in Québec purchase electricity under long-term contracts
with Hydro-Québec executed in 2014, which will expire on December 31, 2029. Upon expiration, Alcoa will have the
option of extending the term of the Baie Comeau contract to February 23, 2036. The smelter located in Baie Comeau,
Québec purchases approximately 73% of its power needs under the Hydro-Québec contract, and the remainder from a
40% owned hydroelectric generating company, Manicouagan Power Limited Partnership.

The Company’s wholly-owned subsidiary, Alcoa Power Generating Inc. (APGI) owns and operates the Yadkin
hydroelectric project, consisting of four dams in North Carolina, and the Warrick coal-fired power plant located in
Indiana.

For several years, APGI has been pursuing a new long-term license for the Yadkin hydroelectric project from the
Federal Energy Regulatory Commission (FERC). In 2007, APGI filed with FERC a Relicensing Settlement Agreement
signed by a majority of interested stakeholders that broadly resolved open issues. The National Environmental Policy
Act process was complete, and a final environmental impact statement was issued in April 2008. The remaining
requirement for relicensing was the issuance by North Carolina of the required water quality certification under
Section 401 of the Clean Water Act (401 WQC). North Carolina’s Department of Environment Quality ((DEQ),
formally known as Department of Environment and Natural Resources (DENR)) issued a 401 WQC to APGI on
October 23, 2015. The period for appeals has passed with no aggrieved party filing an appeal. FERC has been notified
of the final 401 WQC, completing all necessary items required for FERC to process the application.

21

On August 2, 2013, the State of North Carolina filed suit in state court seeking a declaratory ruling that it, not APGI,
owns the Yadkin riverbed beneath the hydroelectric project as well as a portion of the project dams. APGI removed the
riverbed lawsuit to federal court in 2013. On May 6, 2015, U.S. Federal Judge Terrance Boyle declared that the
relevant segment of the Yadkin River was not navigable at the time of North Carolina statehood and issued a ruling on
September 28, 2015 that APGI owns the riverbed for the 37-mile relevant segment. The State of North Carolina has
filed an appeal with the Fourth Circuit Court of Appeals.

Pending completion of the relicensing process, APGI received year-to-year license renewals from FERC starting in
May 2008, and will continue to operate under annual licenses until FERC issues a new license. Since the permanent
closure of the Badin, North Carolina smelter, power generated from APGI’s Yadkin system is largely being sold to an
affiliate, Alcoa Power Marketing LLC, and then into the wholesale market.

APGI generates substantially all of the power used at the Company’s Warrick, Indiana smelter using nearby coal
reserves. Since May 2005, Alcoa has owned the nearby Friendsville, Illinois coal reserves, with the Friendsville Mine
being operated by Vigo Coal Company, Inc. (Vigo Coal). The Friendsville Mine is producing approximately 900,000
tons of coal per year and is scheduled to cease production at the end of March 2016. Liberty Mine, also owned by
Alcoa and operated by Vigo Coal, produces coal and is operating at a level of approximately 1.4 million tons per year.
Friendsville and Liberty Mines together supply 99% of the power plant’s needs. The balance of the coal used is royalty
coal.

In the State of Washington, Alcoa’s Wenatchee smelter is served by a contract with Chelan County Public Utility
District (Chelan PUD) under which Alcoa receives approximately 26% of the hydropower output of Chelan PUD’s
Rocky Reach and Rock Island dams. In November 2015, Alcoa announced the curtailment of the Wenatchee smelter
which was completed by the end of December 2015.

Starting on January 1, 2013, the Intalco smelter began receiving physical power from the Bonneville Power
Administration (BPA) pursuant to a contract executed between Alcoa and BPA, under which Alcoa receives physical
power at the Northwest Power Act mandated industrial firm power (IP) rate through September 30, 2022. In May 2015,
the contract was amended to reduce the amount of physical power received from BPA and allow for additional
purchases of market power.

Prior to 2007, power for the Rockdale smelter in Texas was historically supplied from Company-owned generating
units and Sandow Unit 4 owned by Luminant Generation Company LLC (formerly TXU Generation Company LP)
(Luminant), both of which used lignite supplied by the Company’s Sandow Mine and Three Oaks Mine. Upon
completion of lignite mining in the Sandow Mine in 2005, lignite supply transitioned to the formerly Alcoa-owned
Three Oaks Mine. The Company retired its three wholly-owned generating units at Rockdale (Sandow Units 1, 2 and 3)
in late 2006, and transitioned to an arrangement under which Luminant is to supply all of the Rockdale smelter’s
electricity requirements under a long-term power contract that does not expire until at least the end of 2038, with the
parties having the right to terminate the contract after 2013 if there has been an unfavorable change in law or after 2025
(by Luminant only) if the cost of the electricity exceeds the market price. In August 2007, Luminant and Alcoa closed
on the definitive agreements under which Luminant has constructed and operates a new circulating fluidized bed power
plant (Sandow Unit 5) adjacent to the existing Sandow Unit 4 and, in September 2007, on the sale of Three Oaks Mine
to Luminant. Concurrent with entering into the agreements under which Luminant constructed and operates Sandow
Unit 5, Alcoa and Luminant entered into a power purchase agreement whereby Alcoa purchased power from Luminant.
That Sandow Unit 5 power purchase agreement was terminated by Alcoa, effective December 1, 2010. In June 2008,
Alcoa temporarily idled half of the capacity at the Rockdale smelter and in November 2008 curtailed the remainder of
Rockdale’s smelting capacity. In late 2011, Alcoa announced that it would permanently close two of the six idled
potlines at the smelter. Demolition and remediation activities related to these actions were completed in 2013. On
April 29, 2014, Luminant Generation LLC, Luminant Mining Company LLC, Sandow Power Company LLC and their
affiliated debtors filed petitions under Chapter 11 of the U.S. Bankruptcy Code with the U.S Bankruptcy Court for the
District of Delaware. The Bankruptcy Court has confirmed the debtors’ amended plan of reorganization and has

22

entered an order approving the debtors’ assumption of the Sandow Unit 4 agreement and certain other related
agreements with the Company.

In the Northeast, the Massena West smelter in New York receives physical power from the New York Power Authority
(NYPA) pursuant to a contract between Alcoa and NYPA, which expires in 2045. In December 2015, Alcoa and
NYPA agreed upon a new power contract that will expire in 2019. Upon final approval of the contract by New York
State, which is expected in the first half of 2016, the new power contract for physical power will replace the prior
contract.

Australia – Electricity

In 2015 Alcoa permanently closed the Anglesea power station and associated coal mine in Victoria. The power station
had previously provided electricity to the Point Henry smelter which closed in 2014. Since the Port Henry smelter
closure, electricity was sold into the National Electricity Market (NEM); however a combination of low electricity
prices and significant future capital expenditure meant the facility was no longer viable.

The Portland smelter continues to purchase electricity from the State Electricity Commission of Victoria (SECV) under
a contract with Alcoa Portland Aluminium Pty Ltd, a wholly-owned subsidiary of AofA, that extends to October 2016.
Upon the expiration of this contract, the Portland smelter will purchase power from the NEM variable spot market. In
March 2010, AofA and Eastern Aluminium (Portland) Pty Ltd separately entered into fixed for floating swap contracts
with Loy Yang (now AGL) in order to manage their exposure to the variable energy rates from the NEM. The fixed for
floating swap contract with AGL for the Point Henry smelter was terminated in 2013. The fixed for floating swap
contract with AGL for the Portland smelter operates from the date of expiration of the current contract with the SECV
and continues until December 2036.

Brazil – Electricity

Alumínio owns a 25.74% stake in Consórcio Machadinho, which is the owner of the Machadinho hydroelectric power
plant located in southern Brazil.

Alumínio has a 42.18% interest in Energética Barra Grande S.A., which built the Barra Grande hydroelectric power
plant in southern Brazil.

Alumínio also has a 34.97% share in Serra do Facão Energia S.A., which built the Serra do Facão hydroelectric power
plant in the southeast of Brazil.

Alumínio is also participating in the Estreito hydropower project in northern Brazil, through Estreito Energia S.A. (an
Alumínio wholly owned company) holding a 25.49% stake in Consórcio Estreito Energia, which is the owner of the
hydroelectric power plant.

A consortium in which Alumínio participates and that had received concessions for the Pai Querê hydropower project
in southern Brazil (Alumínio’s share is 35%) decided not to pursue the development of this concession which will be
returned to the Federal Government.

Since May 2015 (after full curtailment of Poços de Caldas and Alumar smelters), the excess generation capacity of
around 460MW has been sold into the market.

Europe – Electricity

Alcoa’s smelters at San Ciprián, La Coruña and Avilés, Spain purchase electricity under bilateral power contracts that
commenced on January 1, 2013. The contracts for San Ciprián and Avilés smelters each have a four-year term
(expiring December 31, 2016). The contract for the La Coruña smelter, which expired on December 31, 2015, has been
extended for an additional year (expiring December 31, 2016).

23

A competitive bidding mechanism to allocate interruptibility rights in Spain was settled during 2014 to be applied
starting from January 1, 2015. The first auction process to allocate rights took place in November 2014, where Alcoa
secured 275MW of interruptibility rights for the 2015 period for the San Ciprián smelter. A second auction process
took place in December 2014, where Alcoa secured an additional 100MW of interruptibility rights for the 2015 period
for the San Ciprián smelter (20x5MW), 120MW for the La Coruña smelter (24x5MW) and 110MW for the Avilés
smelter (22x5MW). The auction process to allocate the rights for the following period took place in the first week of
September 2015, where Alcoa secured interruptibility rights for 2016 in the amount of 375MW for San Ciprián Smelter
(3x90MW + 21x5MW), 115MW for Avilés Smelter (23x5MW) and 120MW for La Coruña smelter (24x5MW).

Alcoa owns two smelters in Norway, Lista and Mosjøen, which have long-term power arrangements in place that
continue until the end of 2019. Financial compensation of the indirect carbon emissions costs passed through in the
electricity bill is received in accordance with EU Commission Guidelines and Norwegian compensation regime.

Iceland – Electricity

Alcoa’s Fjarðaál smelter in eastern Iceland began operation in 2007. Central to those operations is a forty-year power
contract under which Landsvirkjun, the Icelandic national power company, built the Kárahnjúkar dam and hydropower
project, and supplies competitively priced electricity to the smelter. In late 2009, Iceland imposed two new taxes on
power intensive industries, both for a period of three years, from 2010 through 2012. One tax is based on energy
consumption; the other is a pre-payment of certain other charges that was recoverable partly in 2014 and will be fully
recovered by end of 2018. In 2012, Iceland extended the energy consumption tax through 2015.

Spain – Natural Gas

In order to facilitate the full conversion of the San Ciprian, Spain alumina refinery from fuel oil to natural gas, in
October 2013, Alumina Española SA (AE) and Gas Natural Transporte SDG SL (GN) signed a take or pay gas pipeline
utilization agreement. Pursuant to that agreement, the ultimate shareholders of AE, Alcoa Inc. and Alumina Limited,
agreed to guarantee the payment of AE’s contracted gas pipeline utilization over the four years of the commitment
period; in the event AE fails to do so, each shareholder being responsible for its respective proportionate share (i.e.,
60/40). Such commitment came into force six months after the gas pipeline was put into operation by GN. The gas
pipeline was completed in January 2015 and the refinery has switched to natural gas consumption for 100% of its
needs.

Three supply contracts were signed in 2014 for the supply of natural gas to the San Ciprián, Spain alumina refinery
during the 2015 period with Endesa, Union Fenosa Gas and BP, expiring by April 2016, December 2015 and
December 2015, respectively. In 2015, the Endesa supply contract expiring in April 2016 was extended until June
2017, the BP supply contract expiring in December 2015 was extended until December 2016 and a new contract with
Gas Natural Fenosa was signed expiring by December 2016. Pursuant to those agreements, Alcoa Inversiones España,
S.L. and Alumina Limited agreed to guarantee the payment of AE’s obligations under the Endesa contract that expires
in April 2016, each shareholder being responsible for its respective proportionate share (i.e., 60/40). In the same way,
Alcoa Inespal S.A. and Alumina Limited have agreed to guarantee the payment of AE’s obligations under the Gas
Natural Fenosa contract over its respective length, with each entity being responsible for its proportionate share (i.e.,
60/40).

North America – Natural Gas

In order to supply its refinery and smelters in the U.S. and Canada, Alcoa generally procures natural gas on a
competitive bid basis from a variety of sources, including producers in the gas production areas and independent gas
marketers. For Alcoa’s larger consuming locations in Canada and the U.S., the gas commodity and the interstate
pipeline transportation are procured (directly or via the local distribution companies) to provide increased flexibility
and reliability. Contract pricing for gas is typically based on a published industry index or New York Mercantile
Exchange (NYMEX) price. The Company may choose to reduce its exposure to NYMEX pricing by hedging a portion
of required natural gas consumption.

24

Australia – Natural Gas

AofA holds a 20% equity interest in the Dampier-to-Bunbury natural gas pipeline (this interest was purchased in
October 2004). This pipeline transports gas from the northwest gas fields to Alcoa’s alumina refineries and other users
in the Southwest of Western Australia. Alcoa uses gas to co-generate steam and electricity for its alumina refining
processes at the Kwinana, Pinjarra and Wagerup refineries. More than 90% of Alcoa’s gas requirements for the
remainder of the decade are secured under long-term contracts. In 2015, AofA entered into a number of long-term gas
supply agreements which now means a significant portion of Alcoa’s gas supplies are secured to 2030. Alcoa has
remained actively involved with projects aimed at developing cost-based gas supply opportunities.

Patents, Trade Secrets and Trademarks

The Company believes that its domestic and international patent, trade secret and trademark assets provide it with a
significant competitive advantage. The Company’s rights under its patents, as well as the products made and sold under
them, are important to the Company as a whole and, to varying degrees, important to each business segment. The
patents owned by Alcoa generally concern particular products or manufacturing equipment or techniques. Alcoa’s
business as a whole is not, however, materially dependent on any single patent, trade secret or trademark. As a result of
product development and technological advancement, the Company continues to pursue patent protection in
jurisdictions throughout the world. At the end of 2015, the Company’s worldwide patent portfolio consisted of
approximately 986 pending patent applications and 1,923 granted patents.

The Company has a number of trade secrets, mostly regarding manufacturing processes and material compositions that
give many of its businesses important advantages in their markets. The Company continues to strive to improve those
processes and generate new material compositions that provide additional benefits.

The Company also has a number of domestic and international registered trademarks that have significant recognition
within the markets that are served. Examples include the name “Alcoa” and the Alcoa symbol for aluminum products,
Howmet metal castings, Huck® fasteners, Kawneer® building panels and Dura-Bright® wheels with easy-clean surface
treatments. The Company’s rights under its trademarks are important to the Company as a whole and, to varying
degrees, important to each business segment.

25

Competitive Conditions

Alcoa is subject to highly competitive conditions in all aspects of its aluminum and non-aluminum businesses.
Competitors include a variety of both U.S. and non-U.S. companies in all major markets. Innovation, price, quality, and
service are the principal competitive factors in Alcoa’s markets. Where aluminum, titanium and nickel products
compete with other materials—such as steel and plastics for automotive and building applications; magnesium,
composites, and plastics for aerospace and defense applications—aluminum, titanium and nickel’s diverse
characteristics, particularly the strength, light weight, recyclability, and flexibility are also significant factors. Alcoa’s
customer intimacy, advanced manufacturing capability, technology, technical expertise, and innovation in multi-
materials and in specialized alloys provide Alcoa a competitive advantage in certain markets and/or for certain
products. For Alcoa’s segments that market products under Alcoa’s brand names, brand recognition, and brand loyalty
also play a role. In addition Alcoa’s competitive position depends, in part, on the Company’s access to an economical
power supply to sustain its operations in various countries.

Research and Development

Alcoa, a light metals technology leader, engages in research and development programs that include process and
product development, and basic and applied research. Expenditures for research and development (R&D) activities
were $238 million in 2015, $218 million in 2014, and $192 million in 2013.

The Company continued to work on new developments in all business segments in 2015. With a focus on multi-
materials, the Company integrated acquisitions of TITAL, Firth Rixson and RTI which expanded its reach into
aerospace by adding advanced technologies and materials capabilities, particularly in titanium—the world’s fastest-
growing aerospace metal.

The Company continued leveraging new technologies in 2015. Among them, the Company entered into a Joint
Development Agreement with Ford to collaborate on next-generation aluminum alloys for automotive parts using
Micromill technology. Working with Phinergy on advancing an aluminum air battery technology, the Company will
make an equity investment of up to $10 million and will be the exclusive anode provider for applications with auto
OEMs and energy utilities. Additionally, the Company completed its jet engine expansion in Hampton, Virginia. This
facility includes technology that cuts the weight of the Company’s highest-volume jet engine blades by 20 percent and
significantly improves aerodynamic performance.

The Company has invested $60 million in the expansion of its R&D center designed to accelerate the development of
additive manufacturing, with a focus on producing metal powder materials tailored for a range of additive process
technologies. Alcoa will further its development of advanced 3D-printing design and manufacturing techniques—such
as Alcoa’s Ampliforge™ process—to improve production speeds, reduce costs, and achieve geometries not possible
through traditional methods. The investment also leverages the Company’s testing and process control expertise to
overcome challenges with qualifying new 3D-printed parts, starting with aerospace applications.

In 2015 several products spanning various industries were brought to market. Notably, Ford began use of Micromill®
material, and Alcoa and Danieli Group agreed to license intellectual property associated with advanced Micromill®
alloys and process technology. Samsung unveiled its Galaxy S6 Smartphone using 6013 Alcoa Power Plate™ product
for 70 percent greater strength than standard aluminum. The Company launched four foundry alloys that offer strength,
thermal performance, corrosion resistance, and at least 20% better fatigue resistance in automotive applications. In
addition, Dura-Bright® EVO, Alcoa’s most durable, easy-to-maintain commercial truck wheel, was brought to the
North American market.

Environmental Matters

Information relating to environmental matters is included in Note N to the Consolidated Financial Statements under the
caption “Environmental Matters” on pages 130-134. Approved capital expenditures for new or expanded facilities for
environmental control are approximately $60 million for 2016 and $70 million for 2017.

26

Employees

Total worldwide employment at the end of 2015 was approximately 60,000 employees in 26 countries. About 37,000
of these employees are represented by labor unions. The Company believes that relations with its employees and any
applicable union representatives generally are good.

In the U.S., approximately 10,000 employees are represented by various labor unions. The largest collective bargaining
agreement is the master collective bargaining agreement between Alcoa and the United Steelworkers (USW). The
USW master agreement covers approximately 6,100 employees at 11 U.S. locations; the current labor agreement
expires on May 15, 2019. There are 18 other collective bargaining agreements in the U.S. with varying expiration
dates. On a regional basis, collective bargaining agreements with varying expiration dates cover approximately 14,650
employees in Europe and Russia, 13,710 employees in North America, 4,350 employees in Central and South America,
3,100 employees in Australia, and 925 employees in China.

Item 1A. Risk Factors.

Alcoa’s business, financial condition and results of operations may be impacted by a number of factors. In addition to
the factors discussed elsewhere in this report, the following risks and uncertainties could materially harm its business,
financial condition or results of operations, including causing Alcoa’s actual results to differ materially from those
projected in any forward-looking statements. The following list of significant risk factors is not all-inclusive or
necessarily in order of importance. Additional risks and uncertainties not presently known to Alcoa or that Alcoa
currently deems immaterial also may materially adversely affect us in future periods.

28

The aluminum industry and aluminum end-use markets are highly cyclical and are influenced by a number of
factors, including global economic conditions.

The aluminum industry generally is highly cyclical, and Alcoa is subject to cyclical fluctuations in global economic
conditions and aluminum end-use markets. Alcoa sells many products to industries that are cyclical, such as the
commercial construction and transportation, automotive, and aerospace industries, and the demand for its products is
sensitive to, and quickly impacted by, demand for the finished goods manufactured by its customers in these industries,
which may change as a result of changes in the general U.S. or worldwide economy, currency exchange rates, energy
prices or other factors beyond its control.

The demand for aluminum is highly correlated to economic growth. For example, the European sovereign debt crisis
that began in late 2009 had an adverse effect on European demand for aluminum and aluminum products. The Chinese
market is a significant source of global demand for, and supply of, commodities, including aluminum. A sustained
slowdown in China’s economic growth and aluminum demand, or a significant slowdown in other markets, that is not
offset by decreases in supply or by increased aluminum demand in emerging economies, such as India, Brazil, and
several South East Asian countries, could have an adverse effect on the global supply and demand for aluminum and
aluminum prices.

While Alcoa believes that the long-term prospects for aluminum and aluminum products are positive, the Company is
unable to predict the future course of industry variables or the strength of the global economy and the effects of
government intervention. Negative economic conditions, such as a major economic downturn, a prolonged recovery
period, a downturn in the commodity sector, or disruptions in the financial markets, could have a material adverse
effect on Alcoa’s business, financial condition or results of operations.

Alcoa could be materially adversely affected by declines in aluminum prices, including global, regional and
product-specific prices.

The overall price of primary aluminum consists of several components: 1) the underlying base metal component, which
is typically based on quoted prices from the London Metal Exchange (LME); 2) the regional premium, which
comprises the incremental price over the base LME component that is associated with the physical delivery of metal to
a particular region (e.g., the Midwest premium for metal sold in the United States); and 3) the product premium, which
represents the incremental price for receiving physical metal in a particular shape (e.g., coil, billet, slab, rod, etc.) or
alloy. Each of the above three components has its own drivers of variability.

The LME price is typically driven by macroeconomic factors, global supply and demand of aluminum (including
expectations for growth and contraction and the level of global inventories), and financial investors. An imbalance in
global supply and demand of aluminum, such as decreasing demand without corresponding supply declines, could have
a negative impact on aluminum pricing. Speculative trading in aluminum and the influence of hedge funds and other
financial institutions participating in commodity markets have also increased in recent years, potentially contributing to
higher levels of price volatility. In 2015, the cash LME price of aluminum reached a high of $1,919 per metric ton and
a low of $1,424 per metric ton. High LME inventories, or the release of substantial inventories into the market, could
lead to a reduction in the price of aluminum. Declines in the LME price have had a negative impact on Alcoa’s results
of operations.

Additionally, Alcoa’s results could be adversely affected by decreases in regional premiums that participants in the
physical metal market pay for immediate delivery of aluminum. Regional premiums tend to vary based on the supply
of and demand for metal in a particular region and associated transportation costs. LME warehousing rules could cause
aluminum prices to decrease and surpluses have caused regional premiums to decrease, which would have a negative
impact on the Company’s results of operations.

Product premiums generally are a function of supply and demand for a given primary aluminum shape and alloy
combination in a particular region. A sustained weak LME aluminum pricing environment, deterioration in LME
aluminum prices, or a decrease in regional premiums or product premiums could have a material adverse effect on
Alcoa’s business, financial condition, and results of operations or cash flow.

29

LME warehousing rules could cause aluminum prices to decrease.

Since 2013, the LME has been engaged in a program aimed at reforming the rules under which registered warehouses
in its global network operate. The initial rule changes took effect on February 1, 2015, and the LME has announced
additional changes that will be implemented in 2016. These rule changes, and any subsequent changes that the
exchange chooses to make, could impact the supply/demand balance in the primary aluminum physical market and
may impact regional delivery premiums and LME aluminum prices. Decreases in regional delivery premiums and/or
decreases in LME aluminum prices could have a material adverse effect on Alcoa’s business, financial condition, and
results of operations or cash flow.

Alcoa may not be able to realize the expected benefits from its strategy of transforming its portfolio by growing
its value-add business and by creating a lower cost, competitive commodity business by optimizing its portfolio.

Alcoa is continuing to execute on its strategy of transforming its portfolio by growing its value-add business to capture
profitable growth as a lightweight metals innovation leader and by creating a lower cost, competitive commodity
business by optimizing its portfolio. It is investing in its value-add manufacturing and engineering businesses to
capture growth opportunities in strong end markets like automotive and aerospace. Alcoa is building out its value-add
businesses, including by introducing innovative new products and technology solutions, and investing in expansions of
value-add capacity. Alcoa’s growth projects include the joint venture with Ma’aden in Saudi Arabia; the automotive
expansions in Davenport, Iowa and Alcoa, Tennessee; the aluminum lithium capacity expansion in Lafayette, Indiana,
at the Alcoa Technical Center in Pennsylvania and at the Kitts Green plant in the United Kingdom; and the expansion
in aerospace capabilities in La Porte, Indiana, Hampton, Virginia and Davenport, Iowa. From time to time, Alcoa also
pursues growth opportunities that are strategically aligned with its objectives, such as the acquisition of the Firth
Rixson business (completed in November 2014), the acquisition of TITAL (completed in March 2015) and the
acquisition of RTI International Metals (completed in July 2015). In addition, Alcoa is optimizing its rolling mill
portfolio as part of its strategy for profitable growth in the midstream business. At the same time, the Company is
creating a competitive commodity business by taking decisive actions to lower the cost base of its upstream operations,
including closing, selling or curtailing high-cost global smelting capacity, optimizing alumina refining capacity, and
pursuing the sale of its interest in certain other operations.

Alcoa has made, and may continue to plan and execute, acquisitions and divestitures and take other actions to grow or
streamline its portfolio. Although management believes that its strategic actions are beneficial to Alcoa, there is no
assurance that anticipated benefits will be realized. Adverse factors may prevent Alcoa from realizing the benefits of its
growth projects, including unfavorable global economic conditions, currency fluctuations, or unexpected delays in
target timelines. Acquisitions present significant challenges and risks, including the effective integration of the
business into the Company, unanticipated costs and liabilities, and the ability to realize anticipated benefits, such as
growth in market share, revenue or margins, at the levels or in the timeframe expected. The Company may be unable to
manage acquisitions successfully.

With respect to portfolio optimization actions such as divestitures, curtailments and closures, Alcoa may face barriers
to exit from unprofitable businesses or operations, including high exit costs or objections from various stakeholders. In
addition, Alcoa may retain unforeseen liabilities for divested entities if a buyer fails to honor all commitments. Alcoa’s
business operations are capital intensive, and curtailment or closure of operations or facilities may include significant
charges, including employee separation costs, asset impairment charges and other measures.

There can be no assurance that acquisitions, growth investments, divestitures or closures will be undertaken or
completed in their entirety as planned or that they will be beneficial to Alcoa.

Market-driven balancing of global aluminum supply and demand may be disrupted by non-market forces or
other impediments to production closures.

In response to market-driven factors relating to the global supply and demand of aluminum, Alcoa has curtailed or
closed portions of its aluminum production. Certain other aluminum producers have independently undertaken to make
cuts in production as well. However, the existence of non-market forces on global aluminum industry capacity, such as
political pressures in certain countries to keep jobs or to maintain or further develop industry self-sufficiency, may

30

prevent or delay the closure or curtailment of certain producers’ smelters, irrespective of their position on the industry
cost curve. Other production cuts may be impeded by long-term contracts to buy power or raw materials. If industry
overcapacity persists due to the disruption by such non-market forces on the market-driven balancing of the global
supply and demand of aluminum, the resulting weak pricing environment and margin compression may adversely
affect the operating results of aluminum producers, including Alcoa.

Alcoa’s operations consume substantial amounts of energy; profitability may decline if energy costs rise or if
energy supplies are interrupted.

Alcoa’s operations consume substantial amounts of energy. Although Alcoa generally expects to meet the energy
requirements for its alumina refineries and primary aluminum smelters from internal sources or from long-term
contracts, certain conditions could negatively affect Alcoa’s results of operations, including the following:

•

•

•

•

•

•

•

significant increases in electricity costs rendering smelter operations uneconomic;

significant increases in fuel oil or natural gas prices;

unavailability of electrical power or other energy sources due to droughts, hurricanes or other natural causes;

unavailability of energy due to energy shortages resulting in insufficient supplies to serve consumers;

interruptions in energy supply or unplanned outages due to equipment failure or other causes;

curtailment of one or more refineries or smelters due to the inability to extend energy contracts upon
expiration or to negotiate new arrangements on cost-effective terms or due to the unavailability of energy at
competitive rates; or

curtailment of one or more smelters due to a regulatory authority’s determination that power supply
interruptibility rights granted to Alcoa under an interruptibility regime in place under the laws of the country
in which the smelter is located do not comply with the regulatory authority’s state aid rules, thus rendering
the smelter operations that had been relying on such country’s interruptibility regime uneconomic.

If events such as those listed above were to occur, the resulting high energy costs or the disruption of an energy source
or the requirement to repay all or a portion of the benefit Alcoa received under a power supply interruptibility regime
could have a material adverse effect on Alcoa’s business and results of operations.

Alcoa’s profitability could be adversely affected by increases in the cost of raw materials or by significant lag
effects of decreases in commodity or LME-linked costs.

Alcoa’s results of operations are affected by changes in the cost of raw materials, including energy, carbon products,
caustic soda and other key inputs, as well as freight costs associated with transportation of raw materials to refining and
smelting locations. Alcoa may not be able to fully offset the effects of higher raw material costs or energy costs
through price increases, productivity improvements or cost reduction programs. Similarly, Alcoa’s operating results are
affected by significant lag effects of declines in key costs of production that are commodity or LME-linked. For
example, declines in the LME-linked costs of alumina and power during a particular period may not be adequate to
offset sharp declines in metal price in that period. Increases in the cost of raw materials or decreases in input costs that
are disproportionate to concurrent sharper decreases in the price of aluminum could have a material adverse effect on
Alcoa’s operating results.

Alcoa is exposed to fluctuations in foreign currency exchange rates and interest rates, as well as inflation, and
other economic factors in the countries in which it operates.

Economic factors, including inflation and fluctuations in foreign currency exchange rates and interest rates,
competitive factors in the countries in which Alcoa operates, and continued volatility or deterioration in the global
economic and financial environment could affect Alcoa’s revenues, expenses and results of operations. Changes in the
valuation of the U.S. dollar against other currencies, particularly the Australian dollar, Brazilian real, Canadian dollar,

31

Euro and Norwegian kroner, may affect Alcoa’s profitability as some important inputs are purchased in other
currencies, while the Company’s upstream products are generally sold in U.S. dollars. In addition, although a strong
U.S. dollar generally has a positive impact on Alcoa’s near-term profitability, over a longer term, a strong U.S. dollar
may have an unfavorable impact to Alcoa’s position on the global aluminum cost curve due to Alcoa’s U.S. smelting
portfolio. As the U.S. dollar strengthens, the cost curve shifts down for smelters outside the U.S. but costs for Alcoa’s
U.S. smelting portfolio may not decline.

Alcoa may not be able to successfully realize future targets or goals established for its business segments, at the
levels or by the dates targeted.

From time to time, Alcoa may announce future targets or goals for its business, which are based on the Company’s
then current expectations, estimates, forecasts and projections about the operating environment, economies and markets
in which Alcoa operates. Future targets and goals reflect the Company’s beliefs and assumptions and its perception of
historical trends, then current conditions and expected future developments, as well as other factors management
believes are appropriate in the circumstances. As such, targets and goals are inherently subject to significant business,
economic, competitive and other uncertainties and contingencies regarding future events, including the risks discussed
in this report. The actual outcome may be materially different. There can be no assurance that any targets or goals
established by the Company will be accomplished at the levels or by the dates targeted, if at all. Failure to achieve the
targets or goals by the Company may have a material adverse effect on its business, financial condition, results of
operations or the market price of its securities.

Alcoa faces significant competition, which may have an adverse effect on profitability.

As discussed in Part I, Item 1. (Business—Competitive Conditions) of this report, the markets for Alcoa’s aluminum
and non-aluminum products are highly competitive. Alcoa’s competitors include a variety of both U.S. and non-U.S.
companies in all major markets, including some that are subsidized. Alcoa’s metals, including aluminum, titanium and
nickel, compete with other materials, such as steel, plastics, composites, ceramics, and glass, among others, for various
applications in Alcoa’s key markets. New product offerings or new technologies in the marketplace may compete with
or replace Alcoa products. The willingness of customers to accept substitutes for the products sold by Alcoa, the ability
of large customers to exert leverage in the marketplace to affect the pricing for fabricated aluminum products, and
technological advancements or other developments by or affecting Alcoa’s competitors or customers could affect
Alcoa’s results of operations. In addition, Alcoa’s competitive position depends, in part, on the Company’s ability to
leverage its innovation expertise across its businesses and key end markets and, in the case of its upstream businesses,
having access to an economical power supply to sustain its operations in various countries.

A downgrade of Alcoa’s credit ratings could limit Alcoa’s ability to obtain future financing, increase its
borrowing costs, increase the pricing of its credit facilities, adversely affect the market price of its securities,
trigger letter of credit or other collateral postings, or otherwise impair its business, financial condition, and
results of operations.

Standard and Poor’s Ratings Services currently rates Alcoa’s long-term debt BBB-, the lowest level of investment
grade rating, with a stable ratings outlook (ratings and outlook were affirmed on March 9, 2015). On September 28,
2015, S&P issued a statement that these ratings and outlook for Alcoa were not affected by Alcoa’s plan to separate
into two publicly-traded companies. On May 29, 2013, Moody’s Investors Service downgraded Alcoa’s long-term debt
rating from Baa3 to Ba1, which is below investment grade, and changed the outlook from rating under review to stable.
On April 30, 2015, Moody’s changed the outlook from stable to positive. On September 28, 2015, Moody’s affirmed
these ratings and changed the current outlook from positive to developing based on Alcoa’s plan to separate into two
publicly-traded companies. On January 21, 2016, Moody’s placed Alcoa’s long-term debt rating under review and
changed the current outlook from developing to rating under review, while leaving Alcoa’s short-term debt rating
unchanged. On April 11, 2014, Fitch Ratings downgraded Alcoa’s rating from BBB- to BB+, a below investment grade
rating, and changed the outlook from negative to stable. On April 16, 2015, Fitch Ratings affirmed Alcoa’s rating of

32

BB+ but revised Alcoa’s outlook to positive. On September 30, 2015, Fitch placed these ratings on “ratings watch
positive” based on Alcoa’s plan to separate into two publicly-traded companies.

There can be no assurance that one or more of these or other rating agencies will not take negative actions with respect
to Alcoa’s ratings. Increased debt levels, adverse aluminum market or macroeconomic conditions, a deterioration in the
Company’s debt protection metrics, a contraction in the Company’s liquidity, or other factors could potentially trigger
such actions. A rating agency may lower, suspend or withdraw entirely a rating or place it on negative outlook or watch
if, in that rating agency’s judgment, circumstances so warrant.

A downgrade of Alcoa’s credit ratings by one or more rating agencies could adversely impact the market price of
Alcoa’s securities; adversely affect existing financing (for example, a downgrade by Standard and Poor’s or a further
downgrade by Moody’s would subject Alcoa to higher costs under Alcoa’s Five-Year Revolving Credit Agreement and
certain of its other revolving credit facilities); limit access to the capital (including commercial paper) or credit markets
or otherwise adversely affect the availability of other new financing on favorable terms, if at all; result in more
restrictive covenants in agreements governing the terms of any future indebtedness that the Company incurs; increase
the cost of borrowing or fees on undrawn credit facilities; result in vendors or counterparties seeking collateral or
letters of credit from Alcoa; or otherwise impair Alcoa’s business, financial condition and results of operations.

Cyber attacks and security breaches may threaten the integrity of Alcoa’s intellectual property and other
sensitive information, disrupt its business operations, and result in reputational harm and other negative
consequences that could have a material adverse effect on its financial condition and results of operations.

Alcoa faces global cybersecurity threats, which may range from uncoordinated individual attempts to sophisticated and
targeted measures, known as advanced persistent threats, directed at the Company. Cyber attacks and security breaches
may include, but are not limited to, attempts to access information, computer viruses, denial of service and other
electronic security breaches.

The Company believes that it faces a heightened threat of cyber attacks due to the industries it serves, the locations of
its operations and its technological innovations. The Company has experienced cybersecurity attacks in the past,
including breaches of its information technology systems in which information was taken, and may experience them in
the future, potentially with more frequency or sophistication. Based on information known to date, past attacks have
not had a material impact on Alcoa’s financial condition or results of operations. However, due to the evolving nature
of cybersecurity threats, the scope and impact of any future incident cannot be predicted. While the Company
continually works to safeguard its systems and mitigate potential risks, there is no assurance that such actions will be
sufficient to prevent cyber attacks or security breaches that manipulate or improperly use its systems or networks,
compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt its
operations. The occurrence of such events could negatively impact Alcoa’s reputation and its competitive position and
could result in litigation with third parties, regulatory action, loss of business, potential liability and increased
remediation costs, any of which could have a material adverse effect on its financial condition and results of
operations. In addition, such attacks or breaches could require significant management attention and resources, and
result in the diminution of the value of the Company’s investment in research and development.

Joint ventures and other strategic alliances may not be successful.

Alcoa participates in joint ventures and has formed strategic alliances and may enter into other similar arrangements in
the future. For example, in December 2009, Alcoa formed a joint venture with Ma’aden, the Saudi Arabian Mining
Company, to develop a fully integrated aluminum complex (including a bauxite mine, alumina refinery, aluminum
smelter and rolling mill) in the Kingdom of Saudi Arabia. Although the Company has, in connection with the Saudi
Arabia joint venture and its other existing joint ventures and strategic alliances, sought to protect its interests, joint
ventures and strategic alliances inherently involve special risks. Whether or not Alcoa holds majority interests or
maintains operational control in such arrangements, its partners may:

•

have economic or business interests or goals that are inconsistent with or opposed to those of the Company;

33

•

•

•

exercise veto rights so as to block actions that Alcoa believes to be in its or the joint venture’s or strategic
alliance’s best interests;

take action contrary to Alcoa’s policies or objectives with respect to its investments; or

as a result of financial or other difficulties, be unable or unwilling to fulfill their obligations under the joint
venture, strategic alliance or other agreements, such as contributing capital to expansion or maintenance
projects.

There can be no assurance that Alcoa’s joint ventures or strategic alliances will be beneficial to Alcoa, whether due to
the above-described risks, unfavorable global economic conditions, increases in construction costs, currency
fluctuations, political risks, or other factors.

Alcoa’s business and growth prospects may be negatively impacted by limits in its capital expenditures.

Alcoa requires substantial capital to invest in growth opportunities and to maintain and prolong the life and capacity of
its existing facilities. For 2016, generating positive cash flow from operations that will exceed capital expenditures
continues to be an Alcoa target. Insufficient cash generation or capital project overruns may negatively impact Alcoa’s
ability to fund as planned its sustaining and return-seeking capital projects. Over the long term, Alcoa’s ability to take
advantage of improved aluminum or other market conditions or growth opportunities in its midstream and downstream
businesses may be constrained by earlier capital expenditure restrictions, which could adversely affect the long-term
value of its business and the Company’s position in relation to its competitors.

Alcoa may also need to address commercial and political issues in relation to its reductions in capital expenditures in
certain of the jurisdictions in which it operates. If Alcoa’s interest in its joint ventures is diluted or it loses key
concessions, its growth could be constrained. Any of the foregoing could have a material adverse effect on the
Company’s business, results of operations, financial condition and prospects.

Alcoa’s global operations expose the Company to risks that could adversely affect Alcoa’s business, financial
condition, operating results or cash flows.

Alcoa has operations or activities in numerous countries and regions outside the United States, including Brazil, China,
Europe, Guinea, Russia, and the Kingdom of Saudi Arabia. The Company’s global operations are subject to a number
of risks, including:

•

•

economic and commercial instability risks, including those caused by sovereign and private debt default,
corruption, and changes in local government laws, regulations and policies, such as those related to tariffs
and trade barriers, taxation, exchange controls, employment regulations and repatriation of earnings;

geopolitical risks such as political instability, civil unrest, expropriation, nationalization of properties by a
government, imposition of sanctions, renegotiation or nullification of existing agreements, mining leases and
permits;

• war or terrorist activities;

• major public health issues such as an outbreak of a pandemic or epidemic (such as Sudden Acute Respiratory

Syndrome, Avian Influenza, H7N9 virus, or the Ebola virus), which could cause disruptions in Alcoa’s
operations or workforce;

•

•

difficulties enforcing intellectual property and contractual rights in certain jurisdictions; and

unexpected events, including fires or explosions at facilities, and natural disasters.

While the impact of any of the foregoing factors is difficult to predict, any one or more of them could adversely affect
Alcoa’s business, financial condition, operating results or cash flows. Existing insurance arrangements may not provide
protection for the costs that may arise from such events.

34

An adverse decline in the liability discount rate, lower-than-expected investment return on pension assets and
other factors could affect Alcoa’s results of operations or amount of pension funding contributions in future
periods.

Alcoa’s results of operations may be negatively affected by the amount of expense Alcoa records for its pension and
other postretirement benefit plans, reductions in the fair value of plan assets and other factors. U.S. generally accepted
accounting principles (GAAP) require that Alcoa calculate income or expense for the plans using actuarial valuations.

These valuations reflect assumptions about financial market and other economic conditions, which may change based
on changes in key economic indicators. The most significant year-end assumptions used by Alcoa to estimate pension
or other postretirement benefit income or expense for the following year are the discount rate applied to plan liabilities
and the expected long-term rate of return on plan assets. In addition, Alcoa is required to make an annual measurement
of plan assets and liabilities, which may result in a significant charge to shareholders’ equity. For a discussion
regarding how Alcoa’s financial statements can be affected by pension and other postretirement benefits accounting
policies, see “Critical Accounting Policies and Estimates—Pension and Other Postretirement Benefits” in Part II,
Item 7. (Management’s Discussion and Analysis of Financial Condition and Results of Operations) and Note W to the
Consolidated Financial Statements—Pension and Other Postretirement Benefits in Part II, Item 8. (Financial
Statements and Supplementary Data). Although GAAP expense and pension funding contributions are impacted by
different regulations and requirements, the key economic factors that affect GAAP expense would also likely affect the
amount of cash or securities Alcoa would contribute to the pension plans.

Potential pension contributions include both mandatory amounts required under federal law and discretionary
contributions to improve the plans’ funded status. The Moving Ahead for Progress in the 21st Century Act (“MAP-
21”), enacted in 2012, provided temporary relief for employers like Alcoa who sponsor defined benefit pension plans
related to funding contributions under the Employee Retirement Income Security Act of 1974 by allowing the use of a
25-year average discount rate within an upper and lower range for purposes of determining minimum funding
obligations. In 2014, the Highway and Transportation Funding Act (HATFA) was signed into law. HATFA extended
the relief provided by MAP-21 and modified the interest rates that had been set by MAP-21. In 2015, the Bipartisan
Budget Act of 2015 (BBA 2015) was signed into law. BBA 2015 extends the relief period provided by HAFTA. Alcoa
believes that the relief provided by BBA 2015 will moderately reduce the cash flow sensitivity of the Company’s U.S.
pension plans’ funded status to potential declines in discount rates over the next several years. However, higher than
expected pension contributions due to a decline in the plans’ funded status as a result of declines in the discount rate or
lower-than-expected investment returns on plan assets could have a material negative effect on the Company’s cash
flows. Adverse capital market conditions could result in reductions in the fair value of plan assets and increase the
Company’s liabilities related to such plans, adversely affecting Alcoa’s liquidity and results of operations.

Unanticipated changes in our tax provisions or exposure to additional tax liabilities could affect Alcoa’s future
profitability.

Alcoa is subject to income taxes in both the United States and various non-U.S. jurisdictions. Its domestic and
international tax liabilities are dependent upon the distribution of income among these different jurisdictions. Changes
in applicable domestic or foreign tax laws and regulations, or their interpretation and application, including the
possibility of retroactive effect, could affect the Company’s tax expense and profitability. Alcoa’s tax expense includes
estimates of additional tax that may be incurred for tax exposures and reflects various estimates and assumptions. The
assumptions include assessments of future earnings of the Company that could impact the valuation of its deferred tax
assets. The Company’s future results of operations could be adversely affected by changes in the effective tax rate as a
result of a change in the mix of earnings in countries with differing statutory tax rates, changes in the overall
profitability of the Company, changes in tax legislation and rates, changes in generally accepted accounting principles,
changes in the valuation of deferred tax assets and liabilities, the results of tax audits and examinations of previously
filed tax returns or related litigation and continuing assessments of its tax exposures. Corporate tax reform and tax law
changes continue to be analyzed in the United States and in many other jurisdictions. Significant changes to the U.S.
corporate tax system in particular could have a substantial impact, positive or negative, on Alcoa’s effective tax rate,
cash tax expenditures, and deferred tax assets and liabilities.

35

Union disputes and other employee relations issues could adversely affect Alcoa’s financial results.

A significant portion of Alcoa’s employees are represented by labor unions in a number of countries under various
collective bargaining agreements with varying durations and expiration dates. For more information, see “Employees”
in Part I, Item 1. (Business) of this report. While Alcoa was previously successful in renegotiating the master collective
bargaining agreement with the United Steelworkers (the most recent renegotiation having taken place in June 2014),
Alcoa may not be able to satisfactorily renegotiate that agreement or other collective bargaining agreements in the U.S.
and other countries when they expire. In addition, existing collective bargaining agreements may not prevent a strike or
work stoppage at Alcoa’s facilities in the future. Alcoa may also be subject to general country strikes or work
stoppages unrelated to its business or collective bargaining agreements. Any such work stoppages (or potential work
stoppages) could have a material adverse effect on Alcoa’s financial results.

Alcoa could be adversely affected by changes in the business or financial condition of a significant customer or
customers.

A significant downturn or deterioration in the business or financial condition of a key customer or customers supplied
by Alcoa could affect Alcoa’s results of operations in a particular period. Alcoa’s customers may experience delays in
the launch of new products, labor strikes, diminished liquidity or credit unavailability, weak demand for their products,
or other difficulties in their businesses. If Alcoa is not successful in replacing business lost from such customers,
profitability may be adversely affected.

Alcoa may not be able to successfully develop and implement technology initiatives.

Alcoa is working on new developments for a number of strategic projects in all business segments, including additive
manufacturing, alloy development, engineered finishes and product design, high speed continuous casting and rolling
technology, and other advanced manufacturing technologies. For more information on Alcoa’s research and
development programs, see “Research and Development” in Part I, Item 1. (Business) of this report. There can be no
assurance that such developments or technologies will be commercially feasible or beneficial to Alcoa.

Alcoa’s human resource talent pool may not be adequate to support the Company’s growth.

Alcoa’s existing operations and development projects require highly skilled executives and staff with relevant industry
and technical experience. The inability of the Company or the industry to attract and retain such people may adversely
impact Alcoa’s ability to adequately meet project demands and fill roles in existing operations. Skills shortages in
engineering, technical service, construction and maintenance contractors and other labor market inadequacies may also
impact activities. These shortages may adversely impact the cost and schedule of development projects and the cost
and efficiency of existing operations.

Alcoa may not realize expected benefits from its productivity and cost-reduction initiatives.

Alcoa has undertaken, and may continue to undertake, productivity and cost-reduction initiatives to improve
performance and conserve cash, including new procurement strategies for raw materials, such as backward integration
and non-traditional sourcing from numerous geographies, deployment of company-wide business process models, such
as Alcoa’s degrees of implementation process in which ideas are executed in a disciplined manner to generate savings,
and overhead cost reductions. There is no assurance that these initiatives will be successful or beneficial to Alcoa or
that estimated cost savings from such activities will be realized.

Alcoa may be exposed to significant legal proceedings, investigations or changes in U.S. federal, state or foreign
law, regulation or policy.

Alcoa’s results of operations or liquidity in a particular period could be affected by new or increasingly stringent laws,
regulatory requirements or interpretations, or outcomes of significant legal proceedings or investigations adverse to

36

Alcoa. The Company may experience a change in effective tax rates or become subject to unexpected or rising costs
associated with business operations or provision of health or welfare benefits to employees due to changes in laws,
regulations or policies. The Company is also subject to a variety of legal compliance risks. These risks include, among
other things, potential claims relating to product liability, health and safety, environmental matters, intellectual
property rights, government contracts, taxes, and compliance with U.S. and foreign export laws, anti-bribery laws,
competition laws and sales and trading practices. Alcoa could be subject to fines, penalties, damages (in certain cases,
treble damages), or suspension or debarment from government contracts.

While Alcoa believes it has adopted appropriate risk management and compliance programs to address and reduce
these risks, the global and diverse nature of its operations means that these risks will continue to exist, and additional
legal proceedings and contingencies may arise from time to time. In addition, various factors or developments can lead
the Company to change current estimates of liabilities or make such estimates for matters previously not susceptible of
reasonable estimates, such as a significant judicial ruling or judgment, a significant settlement, significant regulatory
developments or changes in applicable law. A future adverse ruling or settlement or unfavorable changes in laws,
regulations or policies, or other contingencies that the Company cannot predict with certainty could have a material
adverse effect on the Company’s results of operations or cash flows in a particular period. For additional information
regarding the legal proceedings involving the Company, see the discussion in Part I, Item 3. (Legal Proceedings) of this
report and in Note N to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and
Supplementary Data).

Alcoa is subject to a broad range of health, safety and environmental laws and regulations in the jurisdictions in
which it operates and may be exposed to substantial costs and liabilities associated with such laws and
regulations.

Alcoa’s operations worldwide are subject to numerous complex and increasingly stringent health, safety and
environmental laws and regulations. The costs of complying with such laws and regulations, including participation in
assessments and cleanups of sites, as well as internal voluntary programs, are significant and will continue to be so for
the foreseeable future. Environmental laws may impose cleanup liability on owners and occupiers of contaminated
property, including past or divested properties, regardless of whether the owners and occupiers caused the
contamination or whether the activity that caused the contamination was lawful at the time it was conducted.
Environmental matters for which Alcoa may be liable may arise in the future at its present sites, where no problem is
currently known, at previously owned sites, sites previously operated by the Company, sites owned by its predecessors
or sites that it may acquire in the future. Compliance with environmental, health and safety legislation and regulatory
requirements may prove to be more limiting and costly than the Company anticipates. Alcoa’s results of operations or
liquidity in a particular period could be affected by certain health, safety or environmental matters, including
remediation costs and damages related to certain sites. Additionally, evolving regulatory standards and expectations
can result in increased litigation and/or increased costs, all of which can have a material and adverse effect on earnings
and cash flows.

Climate change, climate change legislation or regulations and greenhouse effects may adversely impact Alcoa’s
operations and markets.

Energy is a significant input in a number of Alcoa’s operations. There is growing recognition that consumption of
energy derived from fossil fuels is a contributor to global warming.

A number of governments or governmental bodies have introduced or are contemplating legislative and regulatory
change in response to the potential impacts of climate change. There is also current and emerging regulation, such as
the mandatory renewable energy target in Australia, Québec’s transition to a “cap and trade” system with compliance
required beginning 2013, the European Union Emissions Trading Scheme and the United States’ Clean Power Plan,
which became effective on December 22, 2015. Alcoa will likely see changes in the margins of greenhouse gas-
intensive assets and energy-intensive assets as a result of regulatory impacts in the countries in which the Company
operates. These regulatory mechanisms may be either voluntary or legislated and may impact Alcoa’s operations

37

directly or indirectly through customers or Alcoa’s supply chain. Inconsistency of regulations may also change the
attractiveness of the locations of some of the Company’s assets. Assessments of the potential impact of future climate
change legislation, regulation and international treaties and accords are uncertain, given the wide scope of potential
regulatory change in countries in which Alcoa operates. The Company may realize increased capital expenditures
resulting from required compliance with revised or new legislation or regulations, costs to purchase or profits from
sales of, allowances or credits under a “cap and trade” system, increased insurance premiums and deductibles as new
actuarial tables are developed to reshape coverage, a change in competitive position relative to industry peers and
changes to profit or loss arising from increased or decreased demand for goods produced by the Company and
indirectly, from changes in costs of goods sold.

The potential physical impacts of climate change on the Company’s operations are highly uncertain, and will be
particular to the geographic circumstances. These may include changes in rainfall patterns, shortages of water or other
natural resources, changing sea levels, changing storm patterns and intensities, and changing temperature levels. These
effects may adversely impact the cost, production and financial performance of Alcoa’s operations.

Alcoa’s plan to separate into two independent publicly-traded companies is subject to various risks and
uncertainties and may not be completed in accordance with the expected plans or anticipated timeline, or at all,
and will involve significant time and expense, which could disrupt or adversely affect Alcoa’s business.

On September 28, 2015, Alcoa announced plans to separate into two independent publicly-traded companies: a Value-
Add company comprising the Global Rolled Products, Engineered Products and Solutions, and Transportation and
Construction Solutions segments, and an Upstream company comprising the Alumina and Primary Metals segments.
The separation, which is currently targeted to be completed in the second half of 2016, is subject to approval by
Alcoa’s Board of Directors of the final terms of the separation and market, regulatory and certain other conditions.
Unanticipated developments, including, among others, failure of the separation to qualify for the expected tax
treatment, the possibility that any third-party consents required in connection with the separation will not be received,
material adverse changes in aluminum industry conditions and changes in global economic and financial market
conditions generally, could delay or prevent the completion of the proposed separation, or cause the proposed
separation to occur on terms or conditions that are different or less favorable than expected.

Alcoa expects that the process of completing the proposed separation will be time-consuming and involve significant
costs and expenses, which may be significantly higher than what it currently anticipates and may not yield a benefit if
the separation is not completed. Executing the proposed separation will require significant time and attention from
Alcoa’s senior management and employees, which could disrupt the Company’s ongoing business and adversely affect
the financial results and results of operations. Alcoa may also experience increased difficulties in attracting, retaining
and motivating employees during the pendency of the separation and following its completion, which could harm the
Company’s businesses.

The separation may not achieve some or all of the anticipated benefits.

Alcoa may not realize some or all of the anticipated strategic, financial, operational or other benefits from the
separation. As independent publicly-traded companies, the Value-Add and Upstream companies will be smaller, less
diversified companies with a narrower business focus and may be more vulnerable to changing market conditions, such
as changes in aluminum industry conditions, which could result in increased volatility in their cash flows, working
capital and financing requirements and could materially and adversely affect the respective business, financial
condition and results of operations. Further, there can be no assurance that the combined value of the common stock of
the two publicly-traded companies will be equal to or greater than what the value of Alcoa’s common stock would have
been had the proposed separation not occurred.

The proposed separation may result in disruptions to, and negatively impact Alcoa’s relationships with, the
Company’s suppliers, customers and other business partners.

Uncertainty related to the proposed separation may lead suppliers, customers and other parties with which Alcoa
currently does business or may do business in the future to terminate or attempt to negotiate changes in existing

38

business relationships, or to consider entering into business relationships with parties other than Alcoa. These
disruptions could have a material and adverse effect on Alcoa’s businesses, financial condition, results of operations
and prospects, or the businesses, financial condition, results of operations and prospects of the independent companies
resulting from the separation. The effect of such disruptions could be exacerbated by any delays in the completion of
the separation.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Alcoa’s principal office is located at 390 Park Avenue, New York, New York 10022-4608. Alcoa’s corporate center is
located at 201 Isabella Street, Pittsburgh, Pennsylvania 15212-5858. The Alcoa Technical Center for research and
development is located at 100 Technical Drive, Alcoa Center, Pennsylvania 15069-0001.

Alcoa leases some of its facilities; however, it is the opinion of management that the leases do not materially affect the
continued use of the properties or the properties’ values.

Alcoa believes that its facilities are suitable and adequate for its operations. Although no title examination of properties
owned by Alcoa has been made for the purpose of this report, the Company knows of no material defects in title to any
such properties. See Notes A and H to the financial statements for information on properties, plants and equipment.

Alcoa has active plants and holdings under the following segments and in the following geographic areas:

Item 3. Legal Proceedings.

In the ordinary course of its business, Alcoa is involved in a number of lawsuits and claims, both actual and potential.

Litigation

Italian Energy Matter

As previously reported, before 2002, Alcoa purchased power in Italy in the regulated energy market and received a
drawback of a portion of the price of power under a special tariff in an amount calculated in accordance with a

39

published resolution of the Italian Energy Authority, Energy Authority Resolution n. 204/1999 (“204/1999”). In 2001,
the Energy Authority published another resolution, which clarified that the drawback would be calculated in the same
manner, and in the same amount, in either the regulated or unregulated market. At the beginning of 2002, Alcoa left the
regulated energy market to purchase energy in the unregulated market. Subsequently, in 2004, the Energy Authority
introduced regulation no. 148/2004 which set forth a different method for calculating the special tariff that would result
in a different drawback for the regulated and unregulated markets. Alcoa challenged the new regulation in the
Administrative Court of Milan and received a favorable judgment in 2006. Following this ruling, Alcoa continued to
receive the power price drawback in accordance with the original calculation method, through 2009, when the
European Commission declared all such special tariffs to be impermissible “state aid.” In 2010, the Energy Authority
appealed the 2006 ruling to the Consiglio di Stato (final court of appeal). On December 2, 2011, the Consiglio di Stato
ruled in favor of the Energy Authority and against Alcoa, thus presenting the opportunity for the energy regulators to
seek reimbursement from Alcoa of an amount equal to the difference between the actual drawback amounts received
over the relevant time period, and the drawback as it would have been calculated in accordance with regulation
148/2004. On February 23, 2012, Alcoa filed its appeal of the decision of the Consiglio di Stato (this appeal was
subsequently withdrawn in March 2013). On March 26, 2012, Alcoa received a letter from the agency (Cassa
Conguaglio per il Settore Eletrico (CCSE)) responsible for making and collecting payments on behalf of the Energy
Authority demanding payment in the amount of approximately $110 million (€85 million), including interest. By letter
dated April 5, 2012, Alcoa informed CCSE that it disputes the payment demand of CCSE since (i) CCSE was not
authorized by the Consiglio di Stato decisions to seek payment of any amount, (ii) the decision of the Consiglio di
Stato has been appealed (see above), and (iii) in any event, no interest should be payable. On April 29, 2012, Law
No. 44 of 2012 (“44/2012”) came into effect, changing the method to calculate the drawback. On February 21, 2013,
Alcoa received a revised request letter from CCSE demanding Alcoa’s subsidiary, Alcoa Trasformazioni S.r.l., make a
payment in the amount of $97 million (€76 million), including interest, which reflects a revised calculation
methodology by CCSE and represents the high end of the range of reasonably possible loss associated with this matter
of $0 to $97 million (€76 million). Alcoa has rejected that demand and has formally challenged it through an appeal
before the Administrative Court on April 5, 2013. The Administrative Court scheduled a hearing for December 19,
2013, which was subsequently postponed until April 17, 2014, and further postponed until June 19, 2014. On this date
the Administrative Court listened to Alcoa’s oral argument, and on September 2, 2014, rendered its decision. The
Administrative Court declared the payment request of CCSE and the Energy Authority to Alcoa to be unsubstantiated
based on the 148/2004 resolution with respect to the January 19, 2007 through November 19, 2009 timeframe. On
December 18, 2014, the CCSE and the Energy Authority appealed the Administrative Court’s September 2, 2014
decision; however, a date for the hearing has not been scheduled. As a result of the conclusion of the European
Commission Matter on January 26, 2016 described below, the Company has modified its outlook with respect to a
portion of the pending legal proceedings related to this matter. At this time, the Company is unable to reasonably
predict the ultimate outcome for this matter.

European Commission Matter

As previously reported, in July 2006, the European Commission (EC) announced that it had opened an investigation to
establish whether an extension of the regulated electricity tariff granted by Italy to some energy-intensive industries
complied with European Union (EU) state aid rules. The Italian power tariff extended the tariff that was in force until
December 31, 2005 through November 19, 2009 (Alcoa had been incurring higher power costs at its smelters in Italy
subsequent to the tariff end date through the end of 2012). The extension was originally through 2010, but the date was
changed by legislation adopted by the Italian Parliament effective on August 15, 2009. Prior to expiration of the tariff
in 2005, Alcoa had been operating in Italy for more than 10 years under a power supply structure approved by the EC
in 1996. That measure provided a competitive power supply to the primary aluminum industry and was not considered
state aid from the Italian Government. The EC’s announcement expressed concerns about whether Italy’s extension of
the tariff beyond 2005 was compatible with EU legislation and potentially distorted competition in the European
market of primary aluminum, where energy is an important part of the production costs.

40

On November 19, 2009, the EC announced a decision in this matter stating that the extension of the tariff by Italy
constituted unlawful state aid, in part, and, therefore, the Italian Government is to recover a portion of the benefit
Alcoa received since January 2006 (including interest). The amount of this recovery was to be based on a calculation
prepared by the Italian Government (see below). In late 2009, after discussions with legal counsel and reviewing the
bases on which the EC decided, including the different considerations cited in the EC decision regarding Alcoa’s two
smelters in Italy, Alcoa recorded a charge of $250 million (€173 million), which included $20 million (€14 million) to
write off a receivable from the Italian Government for amounts due under the now expired tariff structure and $230
million (€159 million) to establish a reserve. On April 19, 2010, Alcoa filed an appeal of this decision with the General
Court of the EU (see below). Prior to 2012, Alcoa was involved in other legal proceedings related to this matter that
separately sought the annulment of the EC’s July 2006 decision to open an investigation alleging that such decision did
not follow the applicable procedural rules and requested injunctive relief to suspend the effectiveness of the EC’s
November 19, 2009 decision. However, the decisions by the General Court, and subsequent appeals to the European
Court of Justice, resulted in the denial of these remedies.

In June 2012, Alcoa received formal notification from the Italian Government with a calculated recovery amount of
$375 million (€303 million); this amount was reduced by $65 million (€53 million) for amounts owed by the Italian
Government to Alcoa, resulting in a net payment request of $310 million (€250 million). In a notice published in the
Official Journal of the European Union on September 22, 2012, the EC announced that it had filed an action against the
Italian Government on July 18, 2012 to compel it to collect the recovery amount (on October 17, 2013, the European
Court of Justice ordered Italy to so collect). On September 27, 2012, Alcoa received a request for payment in full of the
$310 million (€250 million) by October 31, 2012. Following discussions with the Italian Government regarding the
timing of such payment, Alcoa paid the requested amount in five quarterly installments of $69 million (€50 million)
beginning in October 2012 through December 2013. Notwithstanding the payments made, Alcoa’s estimate of the most
probable loss of the ultimate outcome of this matter and the low end of the range of reasonably possible loss, which is
$174 million (€159 million) to $332 million (€303 million), remains the $174 million (€159 million) recorded in 2009
(the U.S. dollar amount reflects the effects of foreign currency movements since 2009). Alcoa no longer has a reserve
for this matter; instead, Alcoa has a noncurrent asset reflecting the excess of the total of the five payments made to the
Italian Government over the reserve recorded in 2009. At December 31, 2015, the noncurrent asset was $100 million
(€91 million) (this does not include the $58 million (€53 million) for amounts owed by the Italian Government to
Alcoa mentioned above).

On October 16, 2014, Alcoa received notice from the General Court of the EU that its April 19, 2010 appeal of the
EC’s November 19, 2009 decision was denied. On December 27, 2014, Alcoa filed an appeal of the General Court’s
October 16, 2014 ruling to the European Court of Justice (ECJ). Following submission of the EC’s response to the
appeal, on June 10, 2015, Alcoa filed a request for an oral hearing before the ECJ; no decision on that request was
received. On January 26, 2016, Alcoa was informed that the ECJ had dismissed Alcoa’s December 27, 2014 appeal of
the General Court’s October 16, 2014 ruling. The dismissal of Alcoa’s appeal represents the conclusion of the legal
proceedings in this matter. There will be no further reporting of this matter.

Environmental Matters

Alcoa is involved in proceedings under the Comprehensive Environmental Response, Compensation and Liability Act,
also known as Superfund (CERCLA) or analogous state provisions regarding the usage, disposal, storage or treatment
of hazardous substances at a number of sites in the U.S. The Company has committed to participate, or is engaged in
negotiations with federal or state authorities relative to its alleged liability for participation, in clean-up efforts at
several such sites. The most significant of these matters, including the remediation of the Grasse River in Massena,
NY, are discussed in the Environmental Matters section of Note N to the Consolidated Financial Statements under the
caption “Environmental Matters” on pages 130-134.

As previously reported, in August 2005, Dany Lavoie, a resident of Baie Comeau in the Canadian Province of Québec,
filed a Motion for Authorization to Institute a Class Action and for Designation of a Class Representative against Alcoa
Canada Ltd., Alcoa Limitée, Societe Canadienne de Metaux Reynolds Limitée and Canadian British Aluminum in the

41

Superior Court of Québec in the District of Baie Comeau. Plaintiff seeks to institute the class action on behalf of a
putative class consisting of all past, present and future owners, tenants and residents of Baie Comeau’s St. Georges
neighborhood. He alleges that defendants, as the present and past owners and operators of an aluminum smelter in Baie
Comeau, have negligently allowed the emission of certain contaminants from the smelter, specifically Polycyclic
Aromatic Hydrocarbons or “PAHs,” that have been deposited on the lands and houses of the St. Georges neighborhood
and its environs causing damage to the property of the putative class and causing health concerns for those who inhabit
that neighborhood. Plaintiff originally moved to certify a class action, sought to compel additional remediation to be
conducted by the defendants beyond that already undertaken by them voluntarily, sought an injunction against further
emissions in excess of a limit to be determined by the court in consultation with an independent expert, and sought
money damages on behalf of all class members. In May 2007, the court authorized a class action suit to include only
people who suffered property damage or personal injury damages caused by the emission of PAHs from the smelter. In
September 2007, plaintiffs filed the claim against the original defendants, which the court had authorized in May.
Alcoa has filed its Statement of Defense and plaintiffs filed an Answer to that Statement. Alcoa also filed a Motion for
Particulars with respect to certain paragraphs of plaintiffs’ Answer and a Motion to Strike with respect to certain
paragraphs of plaintiffs’ Answer. In late 2010, the court denied these motions. The Soderberg smelting process that
plaintiffs allege to be the source of emissions of concern has ceased operations and has been dismantled. No further
formal court proceedings or discovery has occurred, while technical advisors nominated by agreement of the parties
confer on potential health impacts of prior emissions. This protocol has been agreed to by the parties who have also
advised the court regarding the process. Plaintiffs have filed a motion seeking appointment of an expert to advise the
court on matters of sampling of homes and standards for interior home remediation. Alcoa has announced its
opposition to that motion. Although initially setting a schedule for briefing, during January 2016, the court notified the
parties that it was suspending that schedule until further notice. No further schedule has been set. Further proceedings
in the case will await resolution of the motion. At this stage of the proceeding, the Company is unable to reasonably
predict an outcome or to estimate a range of reasonably possible loss.

As previously reported, in October 2006, in Barnett, et al. v. Alcoa and Alcoa Fuels, Inc., Warrick Circuit Court,
County of Warrick, Indiana; 87-C01-0601-PL-499, forty-one plaintiffs sued Alcoa Inc. and a subsidiary, asserting
claims similar to those asserted in Musgrave v. Alcoa, et al., Warrick Circuit Court, County of Warrick, Indiana; 87-
C01-0601-CT-006. In November 2007, Alcoa Inc. and its subsidiary filed a motion to dismiss the Barnett cases. In
October 2008, the Warrick County Circuit Court granted Alcoa’s motions to dismiss, dismissing all claims arising out
of alleged occupational exposure to wastes at the Squaw Creek Mine, but in November 2008, the trial court clarified its
ruling, indicating that the order does not dispose of plaintiffs’ personal injury claims based upon alleged “recreational”
or non-occupational exposure. Plaintiffs also filed a “second amended complaint” in response to the court’s orders
granting Alcoa’s motion to dismiss. On July 7, 2010, the court granted the parties’ joint motions for a general
continuance of trial settings. Discovery in this matter remains stayed . The Company is unable to reasonably predict an
outcome or to estimate a range of reasonably possible loss because plaintiffs have merely alleged that their medical
condition is attributable to exposure to materials at the Squaw Creek Mine but no further information is available due
to the discovery stay.

As previously reported, in 1996, Alcoa acquired the Fusina, Italy smelter and rolling operations and the Portovesme,
Italy smelter (both of which are owned by Alcoa’s subsidiary, Alcoa Trasformazioni S.r.l.) from Alumix, an entity
owned by the Italian Government. Alcoa also acquired the extrusion plants located in Feltre and Bolzano, Italy. At the
time of the acquisition, Alumix indemnified Alcoa for pre-existing environmental contamination at the sites. In 2004,
the Italian Ministry of Environment (MOE) issued orders to Alcoa Trasformazioni S.r.l. and Alumix for the
development of a clean-up plan related to soil contamination in excess of allowable limits under legislative decree and
to institute emergency actions and pay natural resource damages. On April 5, 2006, Alcoa Trasformazioni S.r.l.’s
Fusina site was also sued by the MOE and Minister of Public Works (MOPW) in the Civil Court of Venice for an
alleged liability for environmental damages, in parallel with the orders already issued by the MOE. Alcoa
Trasformazioni S.r.l. appealed the orders, defended the civil case for environmental damages and filed suit against
Alumix, as discussed below. Similar issues also existed with respect to the Bolzano and Feltre plants, based on orders

42

issued by local authorities in 2006. Most, if not all, of the underlying activities occurred during the ownership of
Alumix, the governmental entity that sold the Italian plants to Alcoa.

As noted above, in response to the 2006 civil suit by the MOE and MOPW, Alcoa Trasformazioni S.r.l. filed suit
against Alumix claiming indemnification under the original acquisition agreement, but brought that suit in the Court of
Rome due to jurisdictional rules. In June 2008, the parties (Alcoa and now Ligestra S.r.l. (Ligestra), the successor to
Alumix) signed a preliminary agreement by which they have committed to pursue a settlement. The Court of Rome
accepted the request, and postponed the Court’s expert technical assessment, reserving its ability to fix the deadline
depending on the development of negotiations. Alcoa and Ligestra agreed to a settlement in December 2008 with
respect to the Feltre site. Ligestra paid the sum of 1.08 million Euros and Alcoa committed to clean up the site. Further
postponements were granted by the Court of Rome, and the next hearing is fixed for December 20, 2016. In the
meantime, Alcoa Trasformazioni S.r.l. and Ligestra reached a preliminary agreement for settlement of the liabilities
related to Fusina, allocating 80% and 20% of the remediation costs to Ligestra and Alcoa, respectively. In January
2014, a final agreement with Ligestra was signed, and on February 5, 2014, Alcoa signed a final agreement with the
MOE and MOPW settling all environmental issues at the Fusina site. As set out in the agreement between Alcoa and
Ligestra, those two parties will share the remediation costs and environmental damages claimed by the MOE and
MOPW. The remediation project filed by Alcoa and Ligestra has been approved by the MOE. See Note N to the
Consolidated Financial Statements under the caption “Fusina and Portovesme, Italy” on page 131. To provide time for
settlement with Ligestra, the MOE and Alcoa jointly requested and the Civil Court of Venice has granted a series of
postponements of hearings in the Venice trial, assuming that the case will be closed. Following the settlement, the
parties caused the Court to dismiss the proceedings. The proceedings were, however, restarted in April 2015 by the
MOE and MOPW because the Ministers had not ratified the settlement of February 5, 2014. The Ministers announced
in December 2015 that they will ratify the settlement in the following months.

Alcoa and Ligestra have signed a similar agreement relating to the Portovesme site. However, that agreement is
contingent upon final acceptance of the proposed soil remediation project for Portovesme that was rejected by the
MOE in the fourth quarter of 2013. Alcoa submitted a revised proposal in May 2014 and a further revised proposal in
February 2015, in agreement with Ligestra. The MOE issued a Ministerial Decree approving the final project in
October 2015. Work on the soil remediation project will commence in 2016 and is expected to be completed in 2019.
Alcoa and Ligestra are now working on a final groundwater remediation project which is expected to be submitted to
the MOE for review during 2016. While the issuance of the decree for the soil remediation project has provided
reasonable certainty regarding liability for the soil remediation, with respect to the groundwater remediation project
Alcoa is unable to reasonably predict an outcome or to estimate a range of reasonably possible loss beyond what is
described in Footnote N to the Consolidated Financial Statements for several reasons. First, certain costs relating to the
groundwater remediation are not yet fixed. In connection with any proposed groundwater remediation plan for
Portovesme, the Company understands that the MOE has substantial discretion in defining what must be managed
under Italian law, as well as the extent and duration of that remediation program. As a result, the scope and cost of the
final groundwater remediation plan remain uncertain for Portovesme; Alcoa and Ligestra are still negotiating a final
settlement for groundwater remediation at Portovesme, for an allocation of the cost based on the new remediation
project approved by the MOE. In addition, once a groundwater remediation project is submitted, should a final
settlement with Ligestra not be reached, Alcoa should be held responsible only for its share of pollution. However, the
area is impacted by many sources of pollution, as well as historical pollution. Consequently, the allocation of liabilities
would need a very complex technical evaluation by the authorities that has not yet been performed.

As previously reported, on November 30, 2010, Alcoa World Alumina Brasil Ltda. (AWAB) received notice of a
lawsuit that had been filed by the public prosecutors of the State of Pará in Brazil in November 2009. The suit names
AWAB and the State of Pará, which, through its Environmental Agency, had issued the operating license for the
Company’s new bauxite mine in Juruti. The suit concerns the impact of the project on the region’s water system and
alleges that certain conditions of the original installation license were not met by AWAB. In the lawsuit, plaintiffs
requested a preliminary injunction suspending the operating license and ordering payment of compensation. On
April 14, 2010, the court denied plaintiffs’ request. AWAB presented its defense in March 2011, on grounds that it was
in compliance with the terms and conditions of its operating license, which included plans to mitigate the impact of the

43

project on the region’s water system. In April 2011, the State of Pará defended itself in the case asserting that the
operating license contains the necessary plans to mitigate such impact, that the State monitors the performance of
AWAB’s obligations arising out of such license, that the licensing process is valid and legal, and that the suit is
meritless. The Company’s position is that any impact from the project had been fully repaired when the suit was filed.
The Company also believes that Jará Lake has not been affected by any project activity and any evidence of pollution
from the project would be unreliable. Following the preliminary injunction request, the plaintiffs took no further action
until October 2014, when in response to the court’s request and as required by statute, they restated the original
allegations in the lawsuit. The Company is not certain whether or when the action will proceed. Given that this
proceeding is in its preliminary stage and the current uncertainty in this case, the Company is unable to reasonably
predict an outcome or to estimate a range of reasonably possible loss.

As previously reported, by an amended complaint filed April 21, 2005, Alcoa Global Fasteners, Inc. was added as a
defendant in Orange County Water District (OCWD) v. Northrop Corporation, et al., civil action 04cc00715 (Superior
Court of California, County of Orange). OCWD alleges contamination or threatened contamination of a drinking water
aquifer by Alcoa, certain of the entities that preceded Alcoa at the same locations as property owners and/or operators,
and other current and former industrial and manufacturing businesses that operated in Orange County in past decades.
OCWD seeks to recover the cost of aquifer remediation and attorney’s fees. Trial on statutory, non-jury claims
commenced on February 10, 2012, and continued through September 2012 when the case was submitted to the court
for decision. On December 11, 2012, the court issued its tentative ruling in the matter dismissing plaintiff OCWD’s
remaining statutory claims against all defendants. The court’s tentative ruling also invited further briefing on the
decision and it is subject to modification. On January 21, 2013, defendants filed a joint brief responding to ten specific
questions posed by the court’s tentative ruling. The joint brief argued that the court should make further findings of fact
and law in favor of the defendants in response to the ten questions. Alcoa Global Fasteners, Inc. also filed a separate
brief on two of the questions arguing that the court should determine that it is neither a cause of ground water
contamination nor a cause of plaintiff’s incurred costs. Remaining in the case at this time are common law trespass and
nuisance claims for a Phase II trial which has not been scheduled. OCWD has asserted a total remedy cost of at least
$150 million plus attorneys’ fees; however, the amount in controversy at this stage is limited to sums already expended
by the OCWD, approximately $4 million. The court has indicated that it is not likely to grant the OCWD’s request for
declaratory relief as to future sums the OCWD expends. On February 28, 2013, the court held a hearing on its tentative
Statement of Decision finding that OCWD had not met its burden on the element of causation and, following that
hearing, on May 10, 2013, issued a supplemental tentative decision, finding that plaintiff had not met its burden of
proof. On that date, the court ordered defendants to submit a proposed statement of decision, followed by filing of
objections and counter-proposed statement of decision by the plaintiff and responses by the defendants. All filings were
completed by September 23, 2013 at which time the matter was submitted to the court for final decision. On
October 29, 2013, the court issued its final Statement of Decision (“SOD”) which resolved the statutory law liability
claims of the Phase I trial favorably to Alcoa and the other Phase I trial defendants. The plaintiff and the trial
defendants disagree on the consequences of the SOD and the Phase I trial on the remaining two tort claims of nuisance
and trespass. On December 19, 2013, the court held a Case Management Conference and approved the parties’
proposed briefing schedule regarding remaining issues. On June 20, 2014, following the full briefing by the parties, the
trial court entered final judgment in favor of Alcoa and the other trial defendants on the remaining tort claims. On
August 18, 2014, the OCWD filed a notice of appeal of the judgment with the Superior Court of the County of Orange.
On October 14, 2015, the OCWD submitted its opening brief. Defendants’ response brief is due March 14, 2016.

St. Croix Proceedings

Abednego and Abraham cases. As previously reported, on January 14, 2010, Alcoa was served with a multi-plaintiff
action complaint involving several thousand individual persons claiming to be residents of St. Croix who are alleged to
have suffered personal injury or property damage from Hurricane Georges or winds blowing material from the St.
Croix Alumina, L.L.C. (“SCA”) facility on the island of St. Croix (U.S. Virgin Islands) since the time of the hurricane.
This complaint, Abednego, et al. v. Alcoa, et al. was filed in the Superior Court of the Virgin Islands, St. Croix
Division. Following an unsuccessful attempt by Alcoa and SCA to remove the case to federal court, the case has been
lodged in the Superior Court. The complaint names as defendants the same entities that were sued in a February 1999

44

action arising out of the impact of Hurricane Georges on the island and added as a defendant the current owner of the
alumina facility property.

Also as previously reported, on March 1, 2012, Alcoa was served with a separate multi-plaintiff action complaint
involving approximately 200 individual persons alleging claims essentially identical to those set forth in the Abednego
v. Alcoa complaint. This complaint, Abraham, et al. v. Alcoa, et al., was filed on behalf of plaintiffs previously
dismissed in the federal court proceeding involving the original litigation over Hurricane Georges impacts. The matter
was originally filed in the Superior Court of the Virgin Islands, St. Croix Division, on March 30, 2011.

Alcoa and other defendants in the Abraham and Abednego cases filed or renewed motions to dismiss each case in
March 2012 and August 2012 following service of the Abraham complaint on Alcoa and remand of the Abednego
complaint to Superior Court, respectively. By order dated August 10, 2015, the Superior Court dismissed plaintiffs’
complaints without prejudice to re-file the complaints individually, rather than as a multi-plaintiff filing. The order also
preserves the defendants’ grounds for dismissal if new, individual complaints are filed.

Glencore Contractual Indemnity Claim. As previously reported, on June 5, 2015, Alcoa World Alumina LLC
(“AWA”) and SCA filed a complaint in Delaware Chancery Court for a declaratory judgment and injunctive relief to
resolve a dispute between Alcoa and Glencore Ltd. (“Glencore”) with respect to claimed obligations under a 1995 asset
purchase agreement between Alcoa and Glencore. The dispute arose from Glencore’s demand that Alcoa indemnify it
for liabilities it may have to pay to Lockheed Martin (“Lockheed”) related to the St. Croix alumina refinery. Lockheed
had earlier filed suit against Glencore in federal court in New York seeking indemnity for liabilities it had incurred and
would incur to the U.S. Virgin Islands to remediate certain properties at the refinery property and claimed that
Glencore was required by an earlier, 1989 purchase agreement to indemnify it. Glencore had demanded that Alcoa
indemnify and defend it in the Lockheed case and threatened to claim over against Alcoa in the New York action
despite exclusive jurisdiction for resolution of disputes under the 1995 purchase agreement being in Delaware. After
Glencore conceded that it was not seeking to add Alcoa to the New York action, AWA and SCA dismissed their
complaint in the Chancery Court case and on August 6, 2015 filed a complaint for declaratory judgment in Delaware
Superior Court. AWA and SCA filed a motion for judgment on the pleadings on September 16, 2015. Glencore
answered AWA’s and SCA’s complaint and asserted counterclaims on August 27, 2015, and on October 2, 2015 filed
its own motion for judgment on the pleadings. Argument on the parties’ motions was held by the court on December 7,
2015 and by order dated February 8, 2016, the court granted Alcoa’s motion and denied Glencore’s motion resulting in
Alcoa not being liable to indemnify Glencore for the Lockheed action. The decision also leaves for pretrial discovery
and possible summary judgment or trial Glencore’s claims for costs and fees it incurred in defending and settling an
earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On February 17, 2016,
Glencore filed notice of its application for interlocutory appeal of the February 8 ruling. AWA and SCA have 10 days
to respond. The Company is unable to reasonably predict an outcome for the remaining claims.

Other Matters

As previously reported, along with various asbestos manufacturers and distributors, Alcoa and its subsidiaries as
premises owners are defendants in several hundred active lawsuits filed on behalf of persons alleging injury
predominantly as a result of occupational exposure to asbestos at various Company facilities. In addition, an Alcoa
subsidiary company has been named, along with a large common group of industrial companies, in a pattern complaint
where the Company’s involvement is not evident. Since 1999, several thousand such complaints have been filed. To
date, the subsidiary has been dismissed from almost every case that was actually placed in line for trial. Alcoa, its
subsidiaries and acquired companies, all have had numerous insurance policies over the years that provide coverage for
asbestos based claims. Many of these policies provide layers of coverage for varying periods of time and for varying
locations. Alcoa has significant insurance coverage and believes that its reserves are adequate for its known asbestos
exposure related liabilities. The costs of defense and settlement have not been and are not expected to be material to the
results of operations, cash flows, and financial position of the Company.

As previously reported, on August 2, 2013, the State of North Carolina, by and through its agency, the North Carolina
Department of Administration, filed a lawsuit against Alcoa Power Generating Inc. (APGI) in Superior Court, Wake
County, North Carolina (Docket No. 13-CVS-10477). The lawsuit asserts ownership of certain submerged lands and

45

hydropower generating structures situated at Alcoa’s Yadkin Hydroelectric Project (the “Yadkin Project”), including
the submerged riverbed of the Yadkin River throughout the Yadkin Project and a portion of the hydroelectric dams that
Alcoa owns and operates pursuant to a license from the Federal Energy Regulatory Commission. The suit seeks
declaratory relief regarding North Carolina’s alleged ownership interests in the riverbed and the dams and further
declaration that Alcoa has no right, license or permission from North Carolina to operate the Yadkin Project. By notice
filed on September 3, 2013, Alcoa removed the matter to the U.S. District Court for the Eastern District of North
Carolina (Docket No. Civil Action No. 5: 13-cv-633). By motion filed September 3, 2013, the Yadkin Riverkeeper
sought permission to intervene in the case. On September 25, 2013, Alcoa filed its answer in the case and also filed its
opposition to the motion to intervene by the Yadkin Riverkeeper. The Court denied the State’s Motion to Remand and
initially permitted the Riverkeeper to intervene although the Riverkeeper has now voluntarily withdrawn as an
intervening party and will participate as amicus.

On July 21, 2014, the parties each filed a motion for summary judgment. On November 20, 2014, the Court denied
Alcoa’s motion for summary judgment and denied in part and granted in part the State of North Carolina’s motions for
summary judgment. The Court held that under North Carolina law, the burden of proof as to title to property is shifted
to a private party opposing a state claim of property ownership. The court conducted a trial on navigability on April 21-
22, 2015, and, after ruling orally from the bench on April 22, 2015, on May 5, 2015, entered Findings of Fact and
Conclusions of Law as to Navigability, ruling in APGI’s favor that the state “failed to meet its burden to prove that the
Relevant Segment, as stipulated by the parties, was navigable for commerce at statehood.” Subsequently, APGI filed a
motion for summary judgment as to title; the state filed opposition papers. On September 28, 2015, the Court granted
summary judgment in APGI’s favor and found that the evidence demonstrates that APGI holds title to the riverbed.
The Court further directed judgment to be entered in APGI’s favor and closed the case. On October 13, 2015, the State
of North Carolina filed notice of its appeal to the United States Court of Appeals for the Fourth Circuit.

Tax

As previously reported, in September 2010, following a corporate income tax audit covering the 2003 through 2005 tax
years, an assessment was received as a result of Spain’s tax authorities disallowing certain interest deductions claimed
by a Spanish consolidated tax group owned by the Company. An appeal of this assessment in Spain’s Central Tax
Administrative Court by the Company was denied in October 2013. In December 2013, the Company filed an appeal of
the assessment in Spain’s National Court.

Additionally, following a corporate income tax audit of the same Spanish tax group for the 2006 through 2009 tax
years, Spain’s tax authorities issued an assessment in July 2013 similarly disallowing certain interest deductions. In
August 2013, the Company filed an appeal of this second assessment in Spain’s Central Tax Administrative Court,
which was denied in January 2015. The Company filed an appeal of this second assessment in Spain’s National Court
in March 2015.

The combined assessments (remeasured for a tax rate change enacted in November 2014) total $263 million (€241
million). The Company believes it has meritorious arguments to support its tax position and intends to vigorously
litigate the assessments through Spain’s court system. However, in the event the Company is unsuccessful, a portion of
the assessments may be offset with existing net operating losses available to the Spanish consolidated tax group.
Additionally, it is possible that the Company may receive similar assessments for tax years subsequent to 2009. At this
time, the Company is unable to reasonably predict an outcome for this matter.

As previously reported, between 2000 and 2002, Alcoa Alumínio (Alumínio) sold approximately 2,000 metric tons of
metal per month from its Poços de Caldas facility, located in the State of Minas Gerais (the “State”), to Alfio, a
customer also located in the State. Sales in the State were exempted from value-added tax (VAT) requirements. Alfio
subsequently sold metal to customers outside of the State, but did not pay the required VAT on those transactions. In
July 2002, Alumínio received an assessment from State auditors on the theory that Alumínio should be jointly and
severally liable with Alfio for the unpaid VAT. In June 2003, the administrative tribunal found Alumínio liable, and
Alumínio filed a judicial case in the State in February 2004 contesting the finding. In May 2005, the Court of First
Instance found Alumínio solely liable, and a panel of a State appeals court confirmed this finding in April 2006.

46

Alumínio filed a special appeal to the Superior Tribunal of Justice (STJ) in Brasilia (the federal capital of Brazil) later
in 2006. In 2011, the STJ (through one of its judges) reversed the judgment of the lower courts, finding that Alumínio
should neither be solely nor jointly and severally liable with Alfio for the VAT, which ruling was then appealed by the
State. In August 2012, the STJ agreed to have the case reheard before a five-judge panel. A decision from this panel is
pending, but additional appeals are likely. At December 31, 2015, the assessment totaled $35 million (R$135 million),
including penalties and interest. While the Company believes it has meritorious defenses, the Company is unable to
reasonably predict an outcome.

Other Contingencies

In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be
instituted or asserted against Alcoa, including those pertaining to environmental, product liability, safety and health,
and tax matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot now
be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity
or results of operations in a particular period could be materially affected by one or more of these other matters.
However, based on facts currently available, management believes that the disposition of these other matters that are
pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of
the Company.

In November 2015, Alcoa adopted changes issued by the Financial Accounting Standards Board to the balance sheet
classification of deferred income taxes (see the Recently Adopted Accounting Guidance section of Note A to the
Consolidated Financial Statements in Part II Item 8 of this Form 10-K). Additionally, for comparative purposes,
management elected to retrospectively apply these changes to all periods presented.

The data presented in the Selected Financial Data table should be read in conjunction with the information provided in

Overview

Our Business

Alcoa is a global leader in lightweight metals engineering and manufacturing. Alcoa’s innovative, multi-material
products, which include aluminum, titanium, and nickel, are used worldwide in aerospace, automotive, commercial
transportation, packaging, building and construction, oil and gas, defense, consumer electronics, and industrial
applications.

50

Alcoa is also the world leader in the production and management of primary aluminum, fabricated aluminum, and
alumina combined, through its active participation in all major aspects of the industry: technology, mining, refining,
smelting, fabricating, and recycling. Aluminum is a commodity that is traded on the London Metal Exchange (LME)
and priced daily. Sales of primary aluminum and alumina represent approximately 40% of Alcoa’s revenues. The price
of aluminum influences the operating results of Alcoa.

Alcoa is a global company operating in 30 countries. Based upon the country where the point of sale occurred, the
United States and Europe generated 55% and 26%, respectively, of Alcoa’s sales in 2015. In addition, Alcoa has
investments and operating activities in, among others, Australia, Brazil, China, Guinea, Iceland, Russia, and Saudi
Arabia. Governmental policies, laws and regulations, and other economic factors, including inflation and fluctuations
in foreign currency exchange rates and interest rates, affect the results of operations in these countries.

Management Review of 2015 and Outlook for the Future

In 2015, growth in global aluminum demand reached 6%, which was slightly less than management’s projection
(7%) at the end of 2014. However, significant market headwinds negatively impacted the smelting portion of Alcoa’s
upstream operations as the average LME price (on 15-day lag) of aluminum declined 10% and regional premiums
decreased substantially (39% in the United States and Canada and 44% in Europe) compared to 2014. The refining
portion of the upstream operations continued to make progress in shifting customer pricing away from the LME
aluminum price to a mixture of alumina index/spot pricing; however, this was overshadowed by a decrease in the
average alumina index/spot price. Conversely, Alcoa’s upstream operations realized the benefit of a stronger U.S.
dollar in 2015 compared to 2014. In the midstream operations, after-tax operating income was stable in 2015 from
2014 despite generating $1,052 less revenue due to the closure and divestiture of six rolling mills, while the
downstream operations received the benefit of $1,310 in combined revenue combined from three acquisitions. Across
all operations, cost headwinds continued to be a challenge; however, management was able to more than offset these
with net productivity improvements.

Separate from the 2015 operational results, management initiated a number of portfolio actions during the year. In the
upstream operations, following similar actions taken in both 2014 and 2013, smelting capacity of 217 kmt was
curtailed (another 230 kmt will be curtailed by the end of June 2016) and 96 kmt (all of which was previously
curtailed) was permanently closed (another 269 kmt will be closed by the end of March 2016). Additionally, refining
capacity of 1,705 kmt was curtailed (another 1,635 kmt will be curtailed by the end of June 2016). Management also
completed the divestiture of another rolling mill (three rolling mills were previously divested in December 2014) in the
midstream operations that was no longer part of the strategic direction of Alcoa. From a growth perspective, Alcoa
completed the acquisition of two businesses, mostly aerospace-related, both of which will enhance the portfolio of
Alcoa’s downstream operations.

As a result of the previously mentioned capacity reductions, Alcoa’s 2015 results were negatively impacted by
significant restructuring charges related to these actions. Additionally, developments in legal matters in Italy, an
assessment of the realizability of certain deferred tax assets, and an impairment of goodwill caused unfavorable
impacts in Alcoa’s 2015 results.

Management continued its focus on liquidity and cash flows, generating incremental improvements in procurement
efficiencies, overhead rationalization, and disciplined capital spending. This focus and the related results enabled Alcoa
to end 2015 with a solid financial position, consistent with the end of 2014.

The following financial information reflects certain key measures of Alcoa’s 2015 results:

•

Sales of $22,534 and Net loss of $322, or $0.31 per diluted share;

• Total segment after-tax operating income of $1,906, a decrease of 3% from 2014;

51

• Cash from operations of $1,582, reduced by $470 in pension plan contributions and a $300 prepayment to

secure a future supply of gas in Australia;

• Capital expenditures of $1,180, under $1,500 for the sixth consecutive year;

• Cash on hand at the end of the year of $1,919, in excess of $1,400 for the seventh consecutive year;

•

Increase in total debt of $251, but a decline of $1,475 since 2008; and

• Total debt of $9,103, Net margin of $1,968, and Depreciation, depletion, and amortization of $1,280 (Net

margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative,
and other expenses; Research and development expenses; and Provision for depreciation, depletion, and
amortization).

In 2016, management is projecting continued growth (increase of 6%) in the global consumption of primary aluminum,
a slight change from that of the last four years, led by China at an estimated 8%. All other regions in the world, except
for Brazil and Russia (both are projected to be flat with 2015), are expected to have positive growth in aluminum
demand over 2015, including North America at an estimated 5%. After considering forecasted added production, along
with expected industry-wide capacity reductions, both of which are mainly driven by China, management anticipates a
deficit in the aluminum market. For alumina, growth in global consumption is estimated to be 6%, and demand is
expected to slightly exceed supply due to capacity reductions in China, as well as other parts of the world.

Management also anticipates improved market conditions for value-add products in the aerospace, building and
construction, packaging, automotive, and industrial gas turbine global end markets, despite declines in certain regions,
while the commercial transportation global end market is expected to decrease. Many of the conditions that drove these
markets in 2015 will continue throughout 2016.

Aerospace is expected to be driven by large commercial aircraft due to a greater than nine-year order backlog. For
building and construction, awarded nonresidential contracts are projected to be up once again in North America while a
slight decline in Europe is expected. In packaging, growth in China and Europe, mainly driven by the penetration of
aluminum in the growing beer segment and the conversion from steel cans to aluminum cans, respectively, is expected
to more than offset a slight decrease in North America. For automotive, growth is anticipated in the United States (due
to the replacement of older vehicles, low borrowing rates, and the decline in gasoline prices) and China (due to
evolving emissions policies based on new clean air legislation enacted in 2014 and a continued increase in the
percentage of the population driving automobiles), as well as Europe. Industrial gas turbines are expected to see growth
as a result of new demand for high technology turbines and upgrades of existing turbines. In commercial transportation,
improving conditions in both Europe and China are expected to be more than offset by weakness in North America,
due to high inventory levels as a result of one of the highest production years ever in 2015 and projected lower orders.

Looking ahead over the next year, management will continue to focus on lowering Alcoa’s refining and smelting
operations on the respective global cost curves to the 21st and 38th percentiles, respectively. At December 31, 2015,
Alcoa’s refining operations were at the 23rd percentile, a two-percentage point improvement from 2014, and its
smelting operations remained at the 43rd percentile on the respective global cost curves. Actions taken to improve
Alcoa’s position on the global alumina cost curve included, in late 2014, the sale of an ownership interest in a mining
and refining joint venture in Jamaica and the conversion of the fuel source from fuel oil to natural gas at a refinery in
Spain, and, in 2015, the curtailment of 1,330 kmt of high-cost capacity in Suriname. Actions taken in the smelting
operations included, in late 2014, the sale of an ownership interest in a smelter in the United States and the renewal of a
power contract at each of the three smelters in Canada, and, in 2015, the curtailment and closure of 170 kmt combined
of high-cost capacity in Brazil. Also, both the refining and smelting operations benefitted from productivity
improvements, new initiatives as well as the full realization of those implemented in 2014. While the benefits of the
actions in the refining operations can be seen in Alcoa’s improved position on the global alumina cost curve at the end
of 2015, the benefits from the actions in the smelting operations were offset by a downward shift in the global
aluminum cost curve, primarily due to the strong U.S. dollar and curtailments/closures of capacity from other smelting
industry participants.

52

Other actions taken in 2015 to help drive a lower position on the respective global cost curves include additional
curtailments and/or closures of 2,100 kmt of refining capacity and 499 kmt of smelting capacity, all within the United
States. The initiation of these actions occurred late in 2015 and will be completed during the first half of 2016;
therefore, management expects to realize the benefits of curtailing/closing this high-cost capacity during 2016.
Additionally, Alcoa has initiatives to drive further productivity improvements during 2016, including from
procurement and overhead programs. Furthermore, the smelter and the refinery at the joint venture in Saudi Arabia are
expected to provide a two-percentage point reduction on each of the respective global cost curves by the end of 2016
(from 2013).

Management will also continue to focus on revenue growth for both the midstream and downstream operations, which
is expected from multiple sources. The midstream operations anticipate positive contributions from both the
Davenport, IA rolling mill facility and Tennessee rolling mill facility (expansion completed in September 2015), both
of which serve the growing demand for aluminum sheet in the U.S. automotive and market as a result of changing
emission regulations. Likewise, the downstream operations expect favorable results from projects completed in late
2014 and throughout 2015 to meet growing demand in both the aerospace and commercial transportation end markets.
These projects include an expansion of aluminum lithium capabilities in Lafayette, IN, expansions in LaPorte, IN and
Hampton, VA to provide nickel-based super alloy structural components and airfoil blades for jet engines, and an
expansion at a facility in Hungary to double production of aluminum wheels. Additionally, the downstream operations
completed three acquisitions (mostly aerospace-related) in November 2014 through July 2015 (see Engineered
Products and Solutions in Segment Information under Results of Operations below) that will incrementally increase
revenue. Furthermore, in 2014 and 2015, Alcoa entered into a number of multi-year supply agreements related to the
aerospace end market valued at approximately $13,500, including six contracts valued at more than $6,700 combined
with four major customers in the aerospace end market. Under one of these six contracts, the midstream operations will
supply aluminum sheet and plate, and under the other five contracts, the downstream operations will supply jet engine
components (including aluminum and aluminum-lithium fan blades), multi-material fastening systems, titanium plate
and billet, and titanium seat track assemblies.

In addition to focusing on the above-mentioned operational improvements, management has committed to executing
the following transaction. On September 28, 2015, Alcoa announced that its Board of Directors approved a plan to
separate into two independent, publicly-traded companies. One company will comprise the Alumina and Primary
Metals segments and the other company will comprise the Global Rolled Products, Engineered Products and Solutions,
and Transportation and Construction Solutions segments. Alcoa is targeting to complete the separation in the second
half of 2016. The transaction is subject to a number of conditions, including, but not limited to, final approval by
Alcoa’s Board of Directors, receipt of a favorable opinion of legal counsel with respect to the tax-free nature of the
transaction for U.S. federal income tax purposes, and the effectiveness of a Form 10 registration statement to be filed
with the U.S. Securities and Exchange Commission. Upon completion of the separation, Alcoa shareholders will own
all of the outstanding shares of both companies. Alcoa may, at any time and for any reason until the proposed
transaction is complete, abandon the separation plan or modify or change its terms.

Results of Operations

Earnings Summary

Net loss attributable to Alcoa for 2015 was $322, or $0.31 per diluted share, compared with Net income attributable to
Alcoa of $268, or $0.21 per share, in 2014. The decrease in results of $590 was mostly due to a lower average realized
price for both aluminum and alumina, a charge for legal matters in Italy, unfavorable price/product mix in the
midstream and downstream operations, an unfavorable change in income taxes due to a higher amount of discrete
income tax charges and nondeductible items, lower energy sales, and higher costs. These negative impacts were
partially offset by net favorable foreign currency movements, net productivity improvements, higher volume in the
midstream and downstream operations, and lower charges and expenses related to a number of portfolio actions (e.g.,
capacity reductions, divestitures, acquisitions).

53

Net income attributable to Alcoa for 2014 was $268, or $0.21 per share, compared with Net loss attributable to Alcoa
of $2,285, or $2.14 per share, in 2013. The improvement in results of $2,553 was primarily due to the absence of all of
the following: an impairment of goodwill, a discrete income tax charge for valuation allowances on certain deferred tax
assets, and charges for the resolution of a legal matter. Other significant changes in results included the following:
higher energy sales, a higher average realized price for primary aluminum, net productivity improvements, and net
favorable foreign currency movements. These other changes were mostly offset by higher charges and expenses related
to a number of portfolio actions (e.g., capacity reductions, divestitures, acquisitions), higher overall input costs, and an
unfavorable change in income taxes due to higher operating results.

Sales—Sales for 2015 were $22,534 compared with sales of $23,906 in 2014, a decline of $1,372, or 6%. The decrease
was primarily due to the absence of sales related to capacity that was closed, sold or curtailed in the midstream and
upstream operations (see Global Rolled Products and Primary Metals in Segment Information below), a lower average
realized price for aluminum in both the upstream and midstream operations and for alumina in the upstream operations,
unfavorable foreign currency movements in the midstream and downstream operations, and lower energy sales (both as
a result of lower pricing and unfavorable foreign currency movements). These negative impacts were partially offset by
the addition of sales from three recently acquired businesses (see Engineered Products and Solutions in Segment
Information below), higher volume across all segments, favorable product mix in the midstream operations, and higher
buy/resell activity for primary aluminum.

Sales for 2014 were $23,906 compared with sales of $23,032 in 2013, an improvement of $874, or 4%. The increase
was mainly the result of higher volumes in the midstream, downstream, and alumina portion of the upstream
operations, higher energy sales resulting from excess power due to curtailed smelter capacity, increased buy/resell
activity for primary aluminum, and a higher average realized price for primary aluminum. These positive impacts were
partially offset by lower primary aluminum volumes, including those related to curtailed and shutdown smelter
capacity, and unfavorable price/product mix in the midstream operations.

Cost of Goods Sold—COGS as a percentage of Sales was 80.2% in 2015 compared with 80.1% in 2014. The
percentage was negatively impacted by a lower average realized price for both aluminum and alumina in the upstream
operations, unfavorable price/product mix in the midstream and downstream operations, lower energy sales, and higher
costs. These negative impacts were mostly offset by net favorable foreign currency movements due to a stronger U.S.
dollar, net productivity improvements across all segments, higher volume in the midstream and downstream
operations, a favorable LIFO (last in, first out) adjustment due to lower prices for aluminum and alumina ($208), lower
inventory write-downs related to the decisions to permanently shut down and/or curtail capacity in the upstream and
midstream operations (difference of $23—see Restructuring and Other Charges below), and the absence of costs
related to a new labor agreement that covers employees at 10 locations in the United States (see below).

COGS as a percentage of Sales was 80.1% in 2014 compared with 83.7% in 2013. The percentage was positively
impacted by net productivity improvements across all segments, both the previously mentioned higher energy sales and
higher average realized price for primary aluminum, net favorable foreign currency movements due to a stronger U.S.
dollar, lower costs for caustic and carbon, and the absence of costs related to a planned maintenance outage in 2013 at a
power plant in Australia. These positive impacts were partially offset by higher costs for bauxite, energy, and labor,
higher inventory write-downs related to the decisions to permanently shut down certain smelter and rolling mill
capacity (difference of $58—see Restructuring and Other Charges below), and costs related to a new labor agreement
that covers employees at 10 locations in the United States (see below).

On June 6, 2014, the United Steelworkers ratified a new five-year labor agreement covering approximately 6,100
employees at 10 U.S. locations; the previous labor agreement expired on May 15, 2014. In 2014, as a result of the
preparation for and ratification of the new agreement, Alcoa recognized $18 ($12 after-tax) in COGS for, among other
items, business contingency costs and a one-time signing bonus for employees. Additionally, as a result of the
provisions of the new labor agreement, a significant plan amendment was adopted by one of Alcoa’s U.S. pension
plans. Accordingly, this plan was required to be remeasured, which resulted in a $13 decrease to 2014 net periodic
benefit cost.

Selling, General Administrative, and Other Expenses—SG&A expenses were $979, or 4.3% of Sales, in 2015
compared with $995, or 4.2% of Sales, in 2014. The decrease of $16 was principally the result of favorable foreign
currency movements due to a stronger U.S. dollar, the absence of SG&A related to closed and sold locations, and lower
acquisition costs ($15), partially offset by expenses for professional and consulting services related to the planned
separation of Alcoa ($24—see Management Review of 2015 and Outlook for the Future above) and new SG&A related
to inorganic growth in the Engineered Products and Solutions segment.

SG&A expenses were $995, or 4.2% of Sales, in 2014 compared with $1,008, or 4.4% of Sales, in 2013. The decline of
$13 was due to decreases in various expenses, including legal and consulting fees and contract services, mostly offset
by costs associated with the acquisition of Firth Rixson ($42—see Engineered Products and Solutions in Segment
Information below) and higher stock-based compensation expense.

Research and Development Expenses—R&D expenses were $238 in 2015 compared with $218 in 2014 and $192 in
2013. The increase in 2015 as compared to 2014 was mainly driven by additional spending related to the upgrade of a
Micromill™ in San Antonio, TX, which was completed during 2015 and began production of automotive sheet on a
limited basis, for the Global Rolled Products segment and additive manufacturing for 3-D printing, partially offset by
lower spending related to inert anode and carbothermic technology for the Primary Metals segment. The increase in
2014 as compared to 2013 was primarily caused by spending related to an upgrade of a Micromill™ in San Antonio,
TX for the Global Rolled Products segment and additional spending related to inert anode and carbothermic technology
for the Primary Metals segment.

Provision for Depreciation, Depletion, and Amortization—The provision for DD&A was $1,280 in 2015 compared
with $1,371 in 2014. The decrease of $91, or 7%, was mostly due to favorable foreign currency movements due to a
stronger U.S. dollar, particularly against the Australian dollar and Brazilian real, and the absence of DD&A ($71)
related to the divestiture and/or permanent closure of five smelters, six rolling mills, one refinery, and one rod mill (see
Alumina, Primary Metals, and Global Rolled Products in Segment Information below), all of which occurred from
March 2014 through June 2015. These positive impacts were partially offset by new DD&A ($93) associated with
three acquisitions that occurred from November 2014 through July 2015 (see Engineered Products and Solutions in
Segment Information below).

The provision for DD&A was $1,371 in 2014 compared with $1,421 in 2013. The decrease of $50, or 4%, was
principally the result of favorable foreign currency movements due to a stronger U.S. dollar, particularly against the
Australian dollar and Brazilian real, and a reduction in expense related to the permanent shutdown of smelter capacity
in Australia, Canada, the United States, and Italy that occurred at different points during both 2013 and 2014 (see
Primary Metals in Segment Information below). These items were somewhat offset by new DD&A associated with
both the acquisition of Firth Rixson in November 2014 (see Engineered Products and Solutions in Segment
Information below) and assets placed into service in January 2014 related to the completed automotive expansion at the
Davenport, IA plant.

Impairment of Goodwill—In 2015 and 2013, Alcoa recognized an impairment of goodwill in the amount of $25 and
$1,731 ($1,719 after noncontrolling interest), respectively, related to the annual impairment review of the soft alloy
extrusion business in Brazil and the Primary Metals segment, respectively, (see Goodwill in Critical Accounting
Policies and estimates below).

and the expected timetable for completion of the plans.

2015 Actions. In 2015, Alcoa recorded Restructuring and other charges of $1,195 ($836 after-tax and noncontrolling
interest), which were comprised of the following components: $438 ($281 after-tax and noncontrolling interest) for exit
costs related to decisions to permanently shut down and demolish three smelters and a power station (see below); $246
($118 after-tax and noncontrolling interest) for the curtailment of two refineries and two smelters (see below); $201
(pre- and after-tax) related to legal matters in Italy; a $161 ($151 after-tax and noncontrolling interest) net loss related
to the March 2015 divestiture of a rolling mill in Russia (see Global Rolled Products in Segment Information below)
and post-closing adjustments associated with three December 2014 divestitures; $143 ($102 after-tax and
noncontrolling interest) for layoff costs, including the separation of approximately 2,100 employees (425 in the
Transportation and Construction Solutions segment, 645 in the Engineered Products and Solutions segment, 380 in the
Primary Metals segment, 90 in the Global Rolled Products segment, 85 in the Alumina segment, and 475 in Corporate);
$34 ($14 after-tax and noncontrolling interest) for asset impairments, virtually all of which was related to prior
capitalized costs for an expansion project at a refinery in Australia that is no longer being pursued; an $18 ($13 after-
tax) gain on the sale of land related to one of the rolling mills in Australia that was permanently closed in December
2014 (see 2014 Actions below); a net charge of $4 (a net credit of $7 after-tax and noncontrolling interest) for other
miscellaneous items; and $14 ($11 after-tax and noncontrolling interest) for the reversal of a number of small layoff
reserves related to prior periods.

During 2015, management initiated various alumina refining and aluminum smelting capacity curtailments and/or
closures. The curtailments were composed of the remaining capacity at all of the following: the São Luís smelter in
Brazil (74 kmt-per-year); the Suriname refinery (1,330 kmt-per-year); the Point Comfort, TX refinery (2,010 kmt-per-
year); and the Wenatchee, WA smelter (143 kmt-per-year). All of the curtailments were completed in 2015 except for
1,635 kmt-per-year at the Point Comfort refinery, which is expected to be completed by the end of June 2016. The
permanent closures were composed of the capacity at the Warrick, IN smelter (269 kmt-per-year) (includes the closure
of a related coal mine) and the infrastructure of the Massena East, NY smelter (potlines were previously shut down in
both 2013 and 2014—see 2013 Actions and 2014 Actions below), as the modernization of this smelter is no longer
being pursued. The shutdown of the Warrick smelter is expected to be completed by the end of March 2016.

The decisions on the above actions were part of a separate 12-month review in refining (2,800 kmt-per-year) and
smelting (500 kmt-per-year) capacity initiated by management in March 2015 for possible curtailment (partial or full),
permanent closure or divestiture. While many factors contributed to each decision, in general, these actions were
initiated to maintain competitiveness amid prevailing market conditions for both alumina and aluminum. Demolition
and remediation activities related to the Warrick smelter and the Massena East location will begin in 2016 and are
expected to be completed by the end of 2020.

Separate from the actions initiated under the reviews described above, in mid-2015, management approved the
permanent shutdown and demolition of the Poços de Caldas smelter (capacity of 96 kmt-per-year) in Brazil and the

56

Anglesea power station (includes the closure of a related coal mine) in Australia. The entire capacity at Poços de
Caldas had been temporarily idled since May 2014 and the Anglesea power station was shut down at the end of August
2015. Demolition and remediation activities related to the Poços de Caldas smelter and the Anglesea power station
began in late 2015 and are expected to be completed by the end of 2026 and 2020, respectively.

The decision on the Poços de Caldas smelter was due to management’s conclusion that the smelter was no longer
competitive as a result of challenging global market conditions for primary aluminum, which led to the initial
curtailment, that have not dissipated and higher costs. For the Anglesea power station, the decision was made because a
sale process did not result in a sale and there would have been imminent operating costs and financial constraints
related to this site in the remainder of 2015 and beyond, including significant costs to source coal from available
resources, necessary maintenance costs, and a depressed outlook for forward electricity prices. The Anglesea power
station previously supplied approximately 40 percent of the power needs for the Point Henry smelter, which was closed
in August 2014 (see 2014 Actions below).

In 2015, costs related to the shutdown and curtailment actions included asset impairments of $217, representing the
write-off of the remaining book value of all related properties, plants, and equipment; $156 for the layoff of
approximately 3,100 employees (1,800 in the Primary Metals segment and 1,300 in the Alumina segment), including
$30 in pension costs; accelerated depreciation of $84 related to certain facilities as they continued to operate during
2015; and $227 in other exit costs. Additionally in 2015, remaining inventories, mostly operating supplies and raw
materials, were written down to their net realizable value, resulting in a charge of $90 ($43 after-tax and noncontrolling
interest), which was recorded in COGS. The other exit costs of $227 represent $76 in asset retirement obligations and
$86 in environmental remediation, both of which were triggered by the decisions to permanently shut down and
demolish the aforementioned structures in the United States, Brazil, and Australia (includes the rehabilitation of a
related coal mine in each of Australia and the United States), and $65 in supplier and customer contract-related costs.

As of December 31, 2015, approximately 1,500 of the 5,200 employees were separated. The remaining separations for
2015 restructuring programs are expected to be completed by the end of 2016. In 2015, cash payments of $42 were
made against layoff reserves related to 2015 restructuring programs.

2014 Actions. In 2014, Alcoa recorded Restructuring and other charges of $1,168 ($703 after-tax and noncontrolling
interest), which were comprised of the following components: $693 ($443 after-tax and noncontrolling interest) for exit
costs related to decisions to permanently shut down and demolish three smelters and two rolling mills (see below); a
$332 ($163 after-tax and noncontrolling interest) net loss for the divestitures of four operations (see Alumina, Primary
Metals, and Global Rolled Products in Segment Information below); $68 ($45 after-tax and noncontrolling interest) for
the temporary curtailment of two smelters and a related production slowdown at one refinery (see below); $51 ($36
after-tax and noncontrolling interest) for layoff costs, including the separation of approximately 1,120 employees (470
in the Engineered Products and Solutions segment, 360 in the Transportation and Construction Solutions segment, 45
in the Global Rolled Products segment, 60 in the Alumina and Primary Metals segments combined, and 185 in
Corporate); $34 ($26 after-tax) for asset impairments related to prior capitalized costs for a modernization project at a
smelter in Canada that is no longer being pursued; a net charge of $18 ($11 after-tax and noncontrolling interest) for
other miscellaneous items, including $2 ($2 after-tax) for asset impairments and accelerated depreciation; and $28 ($21
after-tax and noncontrolling interest) for the reversal of a number of layoff reserves related to prior periods, including
those associated with a smelter in Italy due to changes in facts and circumstances (see below).

In early 2014, management approved the permanent shutdown and demolition of the remaining capacity (84 kmt-per-
year) at the Massena East, NY smelter and the full capacity (190 kmt-per-year) at the Point Henry smelter in Australia.
The capacity at Massena East was fully shut down by the end of March 2014 and the Point Henry smelter was fully
shut down in August 2014. Demolition and remediation activities related to both the Massena East and Point Henry
smelters began in late 2014 and are expected to be completed by the end of 2020 and 2018, respectively.

The decisions on the Massena East and Point Henry smelters were part of a 15-month review of 460 kmt of smelting
capacity initiated by management in May 2013 (see 2013 Actions below) for possible curtailment. Through this review,

57

management determined that the remaining capacity of the Massena East smelter was no longer competitive and the Point
Henry smelter had no prospect of becoming financially viable. Management also initiated the temporary curtailment of the
remaining capacity (62 kmt-per-year) at the Poços de Caldas smelter and additional capacity (85 kmt-per-year) at the São
Luís smelter, both in Brazil. These curtailments were completed by the end of May 2014. As a result of these curtailments,
200 kmt-per-year of production at the Poços de Caldas refinery was reduced by the end of June 2014.

Also in early 2014, management approved the permanent shutdown of Alcoa’s two rolling mills in Australia, Point
Henry and Yennora. This decision was made due to the significant impact of excess can sheet capacity in both
Australia and Asia. The two rolling mills had a combined can sheet capacity of 200 kmt-per-year and were closed by
the end of 2014. Demolition and remediation activities related to the two rolling mills began in mid-2015 and are
expected to be completed by the end of 2018.

Additionally, in August 2014, management approved the permanent shutdown and demolition of the capacity (150
kmt-per-year) at the Portovesme smelter in Italy, which had been idle since November 2012. This decision was made
because the fundamental reasons that made the Portovesme smelter uncompetitive remained unchanged, including the
lack of a viable long-term power solution. Demolition and remediation activities related to the Portovesme smelter will
begin in 2016 and are expected to be completed by the end of 2020 (delayed due to discussions with the Italian
government and other stakeholders).

In 2014, costs related to the shutdown and curtailment actions included $208 for the layoff of approximately 1,790
employees (1,210 in the Primary Metals segment, 470 in the Global Rolled Products segment, 80 in the Alumina
segment, and 30 in Corporate), including $26 in pension costs; accelerated depreciation of $204 related to the three
facilities in Australia as they continued to operate during 2014; asset impairments of $166 representing the write-off of
the remaining book value of all related properties, plants, and equipment; and $183 in other exit costs. Additionally in
2014, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable
value, resulting in a charge of $67 ($47 after-tax and noncontrolling interest), which was recorded in COGS. The other
exit costs of $183 represent $95 in asset retirement obligations and $42 in environmental remediation, both of which
were triggered by the decisions to permanently shut down and demolish the aforementioned structures in Australia,
Italy, and the United States, and $46 in other related costs, including supplier and customer contract-related costs.

As of December 31, 2015, approximately 2,500 of the 2,870 employees (previously 2,910) were separated. The total
number of employees associated with 2014 restructuring programs was updated to reflect employees, who were
initially identified for separation, accepting other positions within Alcoa and natural attrition. The remaining
separations for 2014 restructuring programs are expected to be completed by the end of 2016. In 2015 and 2014, cash
payments of $62 and $141, respectively, were made against layoff reserves related to 2014 restructuring programs.

2013 Actions. In 2013, Alcoa recorded Restructuring and other charges of $782 ($585 after-tax and noncontrolling
interests), which were comprised of the following components: $391 ($305 after-tax and noncontrolling interest)
related to the resolution of a legal matter; $245 ($183 after-tax) for exit costs related to the permanent shutdown and
demolition of certain structures at three smelter locations (see below); $87 ($61 after-tax and noncontrolling interests)
for layoff costs, including the separation of approximately 1,110 employees (340 in the Primary Metals segment, 250
in the Global Rolled Products segment, 220 in the Engineered Products and Solutions segment, 85 in the Alumina
segment, 75 in the Transportation and Construction Solutions segment and 140 in Corporate), of which 590 relates to a
global overhead reduction program, and $9 in pension plan settlement charges related to previously separated
employees; $25 ($17 after-tax) in net charges, including $12 ($8 after-tax) for asset impairments, related to retirements
and/or the sale of previously idled structures; $25 ($13 after-tax and noncontrolling interests) for asset impairments
related to the write-off of capitalized costs for projects no longer being pursued due to the market environment; a net
charge of $17 ($12 after-tax and noncontrolling interests) for other miscellaneous items, including $3 ($2 after-tax) for
asset impairments; and $8 ($6 after-tax and noncontrolling interests) for the reversal of a number of small layoff
reserves related to prior periods.

In May 2013, management approved the permanent shutdown and demolition of two potlines (capacity of 105 kmt-per-
year) that utilize Soderberg technology at the Baie Comeau smelter in Québec, Canada (remaining capacity of 280

58

kmt-per-year composed of two prebake potlines) and the full capacity (44 kmt-per-year) at the Fusina smelter in Italy.
Additionally, in August 2013, management approved the permanent shutdown and demolition of one potline (capacity
of 41 kmt-per-year) that utilizes Soderberg technology at the Massena East, NY smelter (remaining capacity of 84 kmt-
per-year composed of two Soderberg potlines). The aforementioned Soderberg lines at Baie Comeau and Massena East
were fully shut down by the end of September 2013 while the Fusina smelter was previously temporarily idled in 2010.
Demolition and remediation activities related to all three facilities began in late 2013 and are expected to be completed
by the end of 2016 for Massena East and by the end of 2017 for both Baie Comeau and Fusina.

The decisions on the Soderberg lines for Baie Comeau and Massena East were part of a 15-month review of 460 kmt of
smelting capacity initiated by management in May 2013 for possible curtailment, while the decision on the Fusina
smelter was in addition to the capacity being reviewed. Factors leading to all three decisions were in general focused
on achieving sustained competitiveness and included, among others: lack of an economically viable, long-term power
solution (Italy); changed market fundamentals; other existing idle capacity; and restart costs.

In 2013, exit costs related to the shutdown actions included $114 for the layoff of approximately 550 employees
(Primary Metals segment), including $83 in pension costs; accelerated depreciation of $58 (Baie Comeau) and asset
impairments of $18 (Fusina and Massena East) representing the write-off of the remaining book value of all related
properties, plants, and equipment; and $55 in other exit costs. Additionally in 2013, remaining inventories, mostly
operating supplies and raw materials, were written down to their net realizable value resulting in a charge of $9 ($6
after-tax), which was recorded in COGS. The other exit costs of $55 represent $48 in asset retirement obligations and
$5 in environmental remediation, both of which were triggered by the decisions to permanently shut down and
demolish these structures, and $2 in other related costs.

As of December 31, 2015, the separations associated with 2013 restructuring programs were essentially complete. In
2015, 2014, and 2013, cash payments of $7, $39, and $33, respectively, were made against layoff reserves related to
2013 restructuring programs.

Interest Expense—Interest expense was $498 in 2015 compared with $473 in 2014. The increase of $25, or 5%, was
primarily due to an 8% higher average debt level, somewhat offset by the absence of fees paid associated with the
execution and termination of a 364-day senior unsecured bridge term loan facility related to the then-planned
acquisition of Firth Rixson ($13—see Engineered Products and Solutions in Segment Information below). The higher
average debt level was mostly attributable to higher outstanding long-term debt due to the September 2014 issuance of
$1,250 in 5.125% Notes, the proceeds of which were used to pay a portion of the purchase price of the Firth Rixson
acquisition.

Interest expense was $473 in 2014 compared with $453 in 2013. The increase of $20, or 4%, was principally caused by
lower capitalized interest ($43), largely due to the progress completed at the aluminum complex in Saudi Arabia, and
fees paid associated with the execution and termination of a 364-day senior unsecured bridge term loan facility related
to the then-planned acquisition of Firth Rixson ($13—see Engineered Products and Solutions in Segment Information
below). These items were partially offset by a 3% lower average debt level and lower amortization of debt-related costs

59

due to the conversion of convertible notes. The lower average debt level was mostly attributable to lower outstanding
long-term debt due to the March 2014 conversion of $575 in 5.25% Convertible Notes and the June 2013 repayment of
$422 in 6.00% Notes, partially offset by the September 2014 issuance of $1,250 in 5.125% Notes.

Other Expenses (Income), net—Other expenses, net was $2 in 2015 compared with $47 in 2014. The decrease of $45
was mainly the result of a gain on the sale of land both around the Lake Charles, LA anode facility and at Alcoa’s
former Sherwin, TX refinery site ($49) and the remaining equity investment in a China rolling mill ($19) and a
favorable change in deferred compensation. These items were somewhat offset by the absence of a gain on the sale of a
mining interest in Suriname ($28) and a portion of an equity investment in a China rolling mill ($14), an unfavorable
change in the cash surrender value of company-owned life insurance, and a net unfavorable change in mark-to-market
derivative contracts.

Other expenses, net was $47 in 2014 compared with Other income, net of $25 in 2013. The change of $72 was mostly
due to an unfavorable change in mark-to-market derivative aluminum contracts ($42), net unfavorable foreign currency
movements ($34), a higher equity loss related to Alcoa’s share of the joint venture in Saudi Arabia due to start-up costs
of the entire complex, including restart costs for one of the smelter potlines that was previously shut down due to a
period of instability, and a smaller improvement in the cash surrender value of company-owned life insurance. These
items were somewhat offset by a gain on the sale of a mining interest in Suriname ($28) and a portion of an equity
investment in a China rolling mill ($14).

Income Taxes—Alcoa’s effective tax rate was 179.4% (provision on income) in 2015 compared with the U.S. federal
statutory rate of 35%. The effective tax rate differs from the U.S. federal statutory rate principally due to a $190
discrete income tax charge for valuation allowances on certain deferred tax assets in the United States and Iceland (see
Income Taxes in Critical Accounting Policies and Estimates below), a $201 charge for legal matters in Italy (see
Restructuring and Other Charges above) and a $25 impairment of goodwill (see Impairment of Goodwill above) that
are nondeductible for income tax purposes, a loss on the sale of a rolling mill in Russia (see Global Rolled Products in
Segment Information below) for which no tax benefit was recognized, a $34 net discrete income tax charge as
described below, and restructuring charges related to the curtailment of a refinery in Suriname (see Restructuring and
Other Charges above), a portion for which no tax benefit was recognized.

In 2015, Alcoa World Alumina and Chemicals (AWAC), a joint venture owned 60% by Alcoa and 40% by Alumina
Limited (Alcoa consolidates AWAC for financial reporting purposes), recognized an $85 discrete income tax charge
for a valuation allowance on certain deferred tax assets in Suriname (see Income Taxes in Critical Accounting Policies
and Estimates below), which were related mostly to employee benefits and tax loss carryforwards. Alcoa also had a
$51 deferred tax liability related to its 60%-share of these deferred tax assets that was written off as a result of the
valuation allowance recognized by AWAC.

Alcoa’s effective tax rate was 64.4% (provision on income) in 2014 compared with the U.S. federal statutory rate of
35%. The effective tax rate differs from the U.S. federal statutory rate mainly due to restructuring charges related to
operations in Italy (no tax benefit) and Australia (benefit at a lower tax rate) (see Restructuring and Other Charges
above), a $52 ($31 after noncontrolling interest) discrete income tax charge related to a tax rate change in Brazil (see
below), a loss on the sale of three rolling mills in Europe (no tax benefit) (see Global Rolled Products in Segment
Information below), and a $27 ($16 after noncontrolling interest) discrete income tax charge for the remeasurement of
certain deferred tax assets of a subsidiary in Spain due to a November 2014 enacted tax rate change (from 30% in 2014
to 28% in 2015 to 25% in 2016). These items were somewhat offset by foreign income taxed in lower rate jurisdictions
and a $9 discrete income tax benefit for the release of a valuation allowance related to operations in Germany due to
the initiation of a tax planning strategy.

In December 2011, one of Alcoa’s subsidiaries in Brazil applied for a tax holiday related to its expanded mining and
refining operations. During 2013, the application was amended and re-filed and, separately, a similar application was
filed for another one of the Company’s subsidiaries in Brazil. The deadline for the Brazilian government to deny the
application was July 11, 2014. Since Alcoa did not receive notice that its applications were denied, the tax holiday took
effect automatically on July 12, 2014. As a result, the tax rate applicable to qualified holiday income for these

60

subsidiaries decreased significantly (from 34% to 15.25%), resulting in future cash tax savings over the 10-year
holiday period (retroactively effective as of January 1, 2013). Additionally, a portion of one of the subsidiaries net
deferred tax asset that reverses within the holiday period was remeasured at the new tax rate (the net deferred tax asset
of the other subsidiary was not remeasured since it could still be utilized against the subsidiary’s future earnings not
subject to the tax holiday). This remeasurement resulted in a decrease to that subsidiary’s net deferred tax asset and a
noncash charge to earnings of $52 ($31 after noncontrolling interest).

Alcoa’s effective tax rate was 23.6% in 2013 (provision on a loss) compared with the U.S. federal statutory rate of
35%. The effective tax rate differs (by (58.6)% points) from the U.S. federal statutory rate primarily due to a $1,731
impairment of goodwill (see Impairment of Goodwill above) and a $209 charge for a legal matter (see Restructuring
and Other Charges above) that are nondeductible for income tax purposes, a $372 discrete income tax charge for
valuation allowances on certain deferred tax assets in Spain and the United States (see Income Taxes in Critical
Accounting Policies and Estimates below), restructuring charges related to operations in Canada (benefit at a lower tax
rate) and Italy (no tax benefit) (see Restructuring and Other Charges above), and a $9 discrete income tax charge
related to prior year taxes in Spain and Australia. These items were slightly offset by an $18 discrete income tax
benefit related to new U.S. tax legislation (see below).

On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law and reinstated various expired or
expiring temporary business tax provisions through 2013. Two specific temporary business tax provisions that expired
in 2011 and impacted Alcoa are the look-through rule for payments between related controlled foreign corporations
and the research and experimentation credit. The expiration of these two provisions resulted in Alcoa recognizing a
higher income tax provision of $18 in 2012. As tax law changes are accounted for in the period of enactment, Alcoa
recognized an $18 discrete income tax benefit in 2013 related to the 2012 tax year to reflect the extension of these
provisions. Beginning on January 1, 2014, these two provisions once again expired. On December 19, 2014, the Tax
Increase Prevention Act of 2014 was signed into law, which retroactively extended for one year (i.e. calendar year
2014) a number of the tax provisions that expired at the end of 2013, including the two specific aforementioned
provisions. Beginning on January 1, 2015, these two provisions once again expired. On December 18, 2015, the
Consolidated Appropriations Act, 2016 was signed into law, which retroactively (as of January 1, 2015) extended for
two or five years or made permanent a number of the tax provisions that expired at the end of 2014, including the two
specific aforementioned provisions. The look-through rule for payments between related controlled foreign
corporations was renewed for five years (through 2019) and the research and experimentation credit was made
permanent.

Management anticipates that the effective tax rate in 2016 will be between 30% and 35%. However, business portfolio
actions, changes in the current economic environment, tax legislation or rate changes, currency fluctuations, ability to
realize deferred tax assets, and the results of operations in certain taxing jurisdictions may cause this estimated rate to
fluctuate.

Noncontrolling Interests—Net income attributable to noncontrolling interests was $125 in 2015 compared with Net
loss attributable to noncontrolling interests of $91 in 2014 and Net income attributable to noncontrolling interests of
$41 in 2013. These amounts were virtually all related to Alumina Limited’s 40% ownership interest in AWAC. In
2015, AWAC generated income compared to a loss in both 2014 and 2013.

In 2015, the change in AWAC’s results was principally due to improved operating results, the absence of restructuring
and other charges related to both the permanent shutdown of the Point Henry smelter in Australia (see Restructuring
and Other Charges above) and the divestiture of an ownership interest in a mining and refining joint venture in Jamaica
(see Alumina in Segment Information below), and the absence of a combined $79 ($32 was noncontrolling interest’s
share) discrete income tax charge related to a respective tax rate change in both Brazil and Spain (see Income Taxes
above). These positive impacts were somewhat offset by restructuring charges related to the curtailment of both the
refinery in Suriname and in Point Comfort, TX and the permanent closure of the Anglesea power station and coal mine
(see Restructuring and Other Charges above), an $85 ($34 was noncontrolling interest’s share) discrete income tax
charge for a valuation allowance on certain deferred tax assets (see Income Taxes above), and the absence of a $28
gain ($11 was noncontrolling interest’s share) on the sale of a mining interest in Suriname. The improvement in

61

AWAC’s operating results was largely attributable to net favorable foreign currency movements, net productivity
improvements, and lower input costs, slightly offset by a lower average realized alumina price (see Alumina in
Segment Information below).

In 2014, AWAC generated a smaller loss compared to 2013 mainly driven by the absence of a $384 charge for a legal
matter (see below), improved operating results, and a $28 gain ($11 was noncontrolling interest’s share) on the sale of
a mining interest in Suriname. These positive impacts were mostly offset by restructuring and other charges associated
with both the permanent shutdown of the Point Henry smelter in Australia (see Restructuring and Other Charges
above) and the divestiture of an ownership interest in a mining and refining joint venture in Jamaica (see Alumina in
Segment Information below) and a combined $79 ($32 was noncontrolling interest’s share) discrete income tax charge
related to a respective tax rate change in both Brazil and Spain (see Income Taxes above). The improvement in
AWAC’s operating results was principally due to net favorable foreign currency movements and net productivity
improvements, partially offset by an increase in input costs (see Alumina in Segment Information below). Even though
AWAC generated an overall loss in both 2014 and 2013, the noncontrolling interest’s share resulted in income in 2013
due to the manner in which the charges and costs related to a legal matter were allocated. A description of how these
charges and costs for this legal matter impacted Noncontrolling interests follows.

The noncontrolling interest’s share of AWAC’s charge for a legal matter in 2013 and 2012 was $58 (related to the
aforementioned $384) and $34 (an $85 charge related to the civil portion of the same legal matter), respectively. In
2012, the $34 was based on the 40% ownership interest of Alumina Limited, while, in 2013, the $58 was based on
15%. The application of a different percentage was due to the criteria in a 2012 allocation agreement between Alcoa
and Alumina Limited related to this legal matter being met. Additionally, the $34 charge, as well as costs related to this
legal matter, was retroactively adjusted to reflect the terms of the allocation agreement, resulting in a credit to
Noncontrolling interests of $41 in 2013. In summary, Noncontrolling interests included a charge of $17 and $34 related
to this legal matter in 2013 and 2012, respectively.

Segment Information

Alcoa’s operations consist of five worldwide reportable segments: Alumina, Primary Metals, Global Rolled Products,
Engineered Products and Solutions, and Transportation and Construction Solutions (see below). Segment performance
under Alcoa’s management reporting system is evaluated based on a number of factors; however, the primary measure
of performance is the after-tax operating income (ATOI) of each segment. Certain items such as the impact of LIFO
inventory accounting; metal price lag (see below); interest expense; noncontrolling interests; corporate expense
(general administrative and selling expenses of operating the corporate headquarters and other global administrative
facilities, along with depreciation and amortization on corporate-owned assets); restructuring and other charges; and
other items, including intersegment profit eliminations, differences between tax rates applicable to the segments and
the consolidated effective tax rate, and other nonoperating items such as foreign currency transaction gains/losses and
interest income are excluded from segment ATOI.

Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the
Global Rolled Products and Engineered Products and Solutions (now Engineered Products and Solutions and
Transportation and Construction Solutions—see below) segments in order to enhance the visibility of the underlying
operating performance of these businesses. Metal price lag describes the timing difference created when the average
price of metal sold differs from the average cost of the metal when purchased by the respective segment. In general,
when the price of metal increases, metal price lag is favorable, and when the price of metal decreases, metal price lag is
unfavorable. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total
segment ATOI to consolidated net (loss) income attributable to Alcoa. As a result, this change does not impact the
consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change.

In the third quarter of 2015, management approved a realignment of Alcoa’s Engineered Products and Solutions
segment due to the expansion of this part of Alcoa’s business portfolio through both organic and inorganic growth.
This realignment consisted of moving both the Alcoa Wheel and Transportation Products and Building and
Construction Systems business units to a new reportable segment named Transportation and Construction Solutions.

62

Additionally, the Latin American soft alloy extrusions business previously included in Corporate was moved into the
new Transportation and Construction Solutions segment. The remaining Engineered Products and Solutions segment
consists of the Alcoa Fastening Systems and Rings (renamed to include portions of the Firth Rixson business acquired
in November 2014), Alcoa Power and Propulsion (includes the TITAL business acquired in March 2015), Alcoa
Forgings and Extrusions (includes the other portions of Firth Rixson), and Alcoa Titanium and Engineered Products (a
new business unit that consists solely of the RTI International Metals business acquired in July 2015) business units.
Segment information for all prior periods presented was updated to reflect the new segment structure.

ATOI for all reportable segments totaled $1,906 in 2015, $1,968 in 2014, and $1,267 in 2013. The following
information provides shipments, sales, and ATOI data for each reportable segment, as well as certain production,
realized price, and average cost data, for each of the three years in the period ended December 31, 2015. See Note Q to
the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.

and utilities; depreciation, depletion, and amortization; and plant administrative expenses.

This segment represents a portion of Alcoa’s upstream operations and consists of the Company’s worldwide refining
system. Alumina mines bauxite, from which alumina is produced and then sold directly to external smelter customers,
as well as to the Primary Metals segment (see Primary Metals below), or to customers who process it into industrial
chemical products. More than half of Alumina’s production is sold under supply contracts to third parties worldwide,
while the remainder is used internally by the Primary Metals segment. Alumina produced by this segment and used
internally is transferred to the Primary Metals segment at prevailing market prices. A portion of this segment’s third-
party sales are completed through the use of agents, alumina traders, and distributors. Generally, the sales of this
segment are transacted in U.S. dollars while costs and expenses of this segment are transacted in the local currency of
the respective operations, which are the Australian dollar, the Brazilian real, the U.S. dollar, and the euro.

AWAC is an unincorporated global joint venture between Alcoa and Alumina Limited and consists of a number of
affiliated operating entities, which own, or have an interest in, or operate the bauxite mines and alumina refineries
within the Alumina segment (except for the Poc¸os de Caldas refinery in Brazil and a portion of the Sa˜o Lul´s refinery in
Brazil). Alcoa owns 60% and Alumina Limited owns 40% of these individual entities, which are consolidated by the
Company for financial reporting purposes. As such, the results and analysis presented for the Alumina segment are
inclusive of Alumina Limited’s 40% interest.

In December 2014, AWAC completed the sale of its ownership stake in Jamalco, a bauxite mine and alumina refinery
joint venture in Jamaica, to Noble Group Ltd. Jamalco was 55% owned by a subsidiary of AWAC, and, while owned
by AWAC, 55% of both the operating results and assets and liabilities of this joint venture were included in the
Alumina segment. As it relates to AWAC’s previous 55% ownership stake, the refinery (AWAC’s share of the capacity
was 779 kmt-per-year) generated sales (third-party and intersegment) of approximately $200 in 2013, and the refinery
and mine combined, at the time of divestiture, had approximately 500 employees. See Restructuring and Other Charges
in Results of Operations above.

63

In 2015, alumina production decreased by 886 kmt compared to 2014. The decline was mostly the result of the absence
of production at the Jamalco refinery (see above) and lower production at the Suralco (Suriname—see below) and
Poços de Caldas (Brazil—see below) refineries, slightly offset by higher production at the San Ciprian (Spain) and
Point Comfort (Texas) refineries.

In March 2015, management initiated a 12-month review of 2,800 kmt in refining capacity for possible curtailment
(partial or full), permanent closure or divestiture. This review is part of management’s target to lower Alcoa’s refining
operations on the global alumina cost curve to the 21st percentile (currently 23rd) by the end of 2016. As part of this
review, in 2015, management decided to curtail all of the operating capacity at both the Suralco (1,330 kmt-per-year)
and Point Comfort (2,010 kmt-per-year) refineries. The curtailment of the capacity at Suralco was completed by the
end of November 2015. Management is currently in discussions with the Suriname government to determine the best
long-term solution for Suralco due to limited bauxite reserves and the absence of a long-term energy alternative. The
curtailment of the capacity at Point Comfort is expected to be completed by the end of June 2016 (375 kmt-per-year
was completed by the end of December 2015). Suralco and Point Comfort have nameplate capacity of 2,207 kmt-per-
year and 2,305 kmt-per-year, respectively, of which 877 kmt and 295 kmt, respectively was curtailed prior to the
review. See Restructuring and Other Charges in Results of Operations above for a description of the associated charges
related to these actions.

In 2014, alumina production decreased by 12 kmt compared to 2013. The decline was mainly driven by lower
production at the Poços de Caldas, Jamalco, and San Ciprian refineries, mostly offset by higher production at every
other refinery in the global system. The Poços de Caldas refinery started to reduce production in early 2014 in response
to management’s decision to fully curtail the Poços de Caldas smelter by the end of May 2014 (see Primary Metals
below). As a result, management reduced the alumina production at the Poços de Caldas refinery by approximately 200
kmt-per-year by mid-2014. This reduction was replaced by an increase in production at lower cost refineries within
Alcoa’s global system. Additionally, the decrease at the refinery in Jamaica was due to the absence of production for
one month as a result of the sale of the ownership stake in Jamalco (see above).

Third-party sales for the Alumina segment decreased 2% in 2015 compared with 2014, largely attributable to a 2%
decline in average realized price, somewhat offset by a 1% increase in volume. The change in average realized price
was mostly driven by a decrease in both the average alumina index/spot price and average LME-based price, somewhat
offset by a higher percentage (75% compared to 68%) of smelter-grade alumina shipments linked to an alumina index/
spot price instead of an LME-based price.

Third-party sales for this segment improved 6% in 2014 compared with 2013, primarily related to a 7% improvement
in volume.

Intersegment sales for the Alumina segment declined 13% in both 2015 compared with 2014 and 2014 compared with
2013. The decrease in both periods was mostly the result of lower demand from the Primary Metals segment, as a
result of the closure, curtailment or divestiture of a number of smelters (see Primary Metals below), and a lower
average realized price.

ATOI for the Alumina segment increased $376 in 2015 compared with 2014, mainly caused by net favorable foreign
currency movements due to a stronger U.S. dollar, especially against the Australian dollar and Brazilian real; net
productivity improvements; and lower input costs, including natural gas, fuel oil, and transportation, all of which were
slightly offset by higher labor and maintenance costs. These positive impacts were slightly offset by the previously
mentioned lower average realized price and the absence of a gain on the sale of a mining interest in Suriname ($18).

ATOI for this segment improved $111 in 2014 compared with 2013, mostly due to net favorable foreign currency
movements due to a stronger U.S. dollar, especially against the Australian dollar, net productivity improvements, and a
gain on the sale of a mining interest in Suriname ($18). These positive impacts were partially offset by higher input
costs, including natural gas (particularly higher prices in Australia), bauxite (mainly due to a new mining site in
Suriname), and labor and maintenance, all of which were somewhat offset by lower costs for caustic; and a higher
equity loss due to start-up costs of the bauxite mine and refinery in Saudi Arabia.

64

In 2016, alumina production will be approximately 2,500 kmt lower, mostly due to the curtailment of the Point
Comfort and Suralco refineries. Also, the continued shift towards alumina index and spot pricing is expected to average
85% of third-party smelter-grade alumina shipments. Additionally, net productivity improvements are anticipated.

* Average realized price per metric ton of aluminum includes three elements: a) the underlying base metal component, based on

quoted prices from the LME; b) the regional premium, which represents the incremental price over the base LME component that
is associated with the physical delivery of metal to a particular region (e.g., the Midwest premium for metal sold in the United
States); and c) the product premium, which represents the incremental price for receiving physical metal in a particular shape
(e.g., billet, slab, rod, etc.) or alloy.

**Includes all production-related costs, including raw materials consumed; conversion costs, such as labor, materials, and utilities;

depreciation and amortization; and plant administrative expenses.

This segment represents a portion of Alcoa’s upstream operations and consists of the Company’s worldwide smelting
system. Primary Metals purchases alumina, mostly from the Alumina segment (see Alumina above), from which
primary aluminum is produced and then sold directly to external customers and traders, as well as to Alcoa’s
midstream operations and, to a lesser extent, downstream operations. Results from the sale of aluminum powder, scrap,
and excess energy are also included in this segment, as well as the results of aluminum derivative contracts and buy/
resell activity. Primary aluminum produced by Alcoa and used internally is transferred to other segments at prevailing
market prices. The sale of primary aluminum represents approximately 90% of this segment’s third-party sales. Buy/
resell activity occurs when this segment purchases metal and resells such metal to external customers or the midstream
and downstream operations in order to maximize smelting system efficiency and to meet customer requirements.
Generally, the sales of this segment are transacted in U.S. dollars while costs and expenses of this segment are
transacted in the local currency of the respective operations, which are the U.S. dollar, the euro, the Norwegian kroner,
Icelandic krona, the Canadian dollar, the Brazilian real, and the Australian dollar.

In November 2014, Alcoa completed the sale of an aluminum rod plant located in Bécancour, Québec, Canada to Sural
Laminated Products. This facility takes molten aluminum and shapes it into the form of a rod, which is used by
customers primarily for the transportation of electricity. While owned by Alcoa, the operating results and assets and
liabilities of this plant were included in the Primary Metals segment. In conjunction with this transaction, Alcoa
entered into a multi-year agreement with Sural Laminated Products to supply molten aluminum for the rod plant. The
aluminum rod plant generated sales of approximately $200 in 2013 and, at the time of divestiture, had approximately
60 employees. See Restructuring and Other Charges in Results of Operations above.

In December 2014, Alcoa completed the sale of its 50.33% ownership stake in the Mt. Holly smelter located in Goose
Creek, South Carolina to Century Aluminum Company. While owned by Alcoa, 50.33% of both the operating results
and assets and liabilities related to the smelter were included in the Primary Metals segment. As it relates to Alcoa’s
previous 50.33% ownership stake, the smelter (Alcoa’s share of the capacity was 115 kmt-per-year) generated sales of
approximately $280 in 2013 and, at the time of divestiture, had approximately 250 employees. See Restructuring and
Other Charges in Results of Operations above.

At December 31, 2015, Alcoa had 778 kmt of idle capacity on a base capacity of 3,401 kmt. In 2015, idle capacity
increased 113 kmt compared to 2014, mostly due to the curtailment of 217 kmt combined at a smelter in each the

65

United States and Brazil, partially offset by the permanent closure of the Poços de Caldas smelter in Brazil (96 kmt-
per-year). Base capacity declined 96 kmt between December 31, 2015 and 2014 due to the previously mentioned
permanent closure of the Poços de Caldas smelter. A detailed description of each of these actions follows below.

At December 31, 2014, Alcoa had 665 kmt of idle capacity on a base capacity of 3,497 kmt. In 2014, idle capacity
increased 10 kmt compared to 2013 due to the curtailment of 159 kmt combined at two smelters in Brazil, mostly
offset by the permanent closure of the Portovesme smelter in Italy (150 kmt-per-year). Base capacity declined 540 kmt
between December 31, 2014 and 2013 due to the permanent closure of both a smelter in Australia and two remaining
potlines at a smelter in the United States (274 kmt combined), the previously mentioned permanent closure of the
Portovesme smelter, and the sale of Alcoa’s ownership stake in the Mt. Holly smelter (see above). A detailed
description of each of these actions follows below.

In March 2015, management initiated a 12-month review of 500 kmt in smelting capacity for possible curtailment
(partial or full), permanent closure or divestiture. This review is part of management’s target to lower Alcoa’s smelting
operations on the global aluminum cost curve to the 38th percentile (currently 43rd) by 2016. In summary, under this
review, management approved the curtailment of 447 kmt-per-year and the closure of 269 kmt-per-year. The following
is a description of each action.

Also in March 2015, management decided to curtail the remaining capacity (74 kmt-per-year) at the São Luís smelter
in Brazil; this action was completed in April 2015. In 2013 and 2014 combined, Alcoa curtailed capacity of 194 kmt-
per-year at the São Luís smelter under a prior management review (see below).

Additionally, in November 2015, management decided to curtail the remaining capacity at the Intalco (230 kmt-per-
year) and Wenatchee (143 kmt-per-year) smelters, both in Washington. These two smelters previously had curtailed
capacity of 90 kmt-per-year combined. The curtailment of the remaining capacity at Wenatchee was completed by the
end of December 2015 and the curtailment of the remaining capacity at Intalco is expected to be completed by the end
of June 2016.

Furthermore, in December 2015, management approved the permanent closure of the Warrick, IN smelter (269 kmt-
per-year). This decision was made as this smelter is no longer competitive in light of prevailing market conditions for
the price of aluminum. The shutdown of the Warrick smelter is expected to be completed by the end of March 2016.

Separate from the 2015 smelting capacity review described above, in June 2015, management approved the permanent
closure of the Poços de Caldas smelter effective immediately. The Poços de Caldas smelter had been temporarily idle
since May 2014 (see below) due to challenging global market conditions for primary aluminum and higher operating
costs, which made the smelter uncompetitive. The decision to permanently close the Poços de Caldas smelter was
based on the fact that these underlying conditions had not improved.

In May 2013, management initiated a 15-month review of 460 kmt in smelting capacity for possible curtailment. This
review was aimed at maintaining Alcoa’s competitiveness despite falling aluminum prices and focused on the highest-
cost smelting capacity and those plants that have long-term risk due to factors such as energy costs or regulatory
uncertainty. In 2014, an additional 250 kmt of smelting capacity was included in the review. In summary, under this
review, management approved the closure of 146 kmt-per-year and 274 kmt-per-year and the curtailment of 131 kmt-
per-year and 159 kmt-per-year in 2013 and 2014, respectively. The following is a description of each action.

Also in May 2013, management approved the permanent closure of two potlines (105 kmt-per-year) that utilize
Soderberg technology at the Baie Comeau smelter in Quebec, Canada. Additionally, in August 2013, management
approved the permanent closure of one potline (41 kmt-per-year) that utilizes Soderberg technology at the Massena
East, NY smelter. The shutdown of these three lines was completed by the end of September 2013. The Baie Comeau
smelter has a remaining capacity of 280 kmt-per-year composed of two prebake potlines and the Massena East smelter
had a remaining capacity of 84 kmt-per-year composed of two Soderberg potlines (see below).

66

Additionally, in August 2013, management decided to curtail 97 kmt-per-year at the São Luís smelter and 31 kmt-per-
year at the Poços de Caldas smelter. This action was also completed by the end of September 2013. An additional 3
kmt-per-year was curtailed at the Poços de Caldas smelter by the end of 2013.

In January 2014, management approved the permanent closure of the remaining capacity (84 kmt-per-year) at the
Massena East smelter, which represented two Soderberg potlines that were no longer competitive. This shutdown was
completed by the end of March 2014. In February 2014, management approved the permanent closure of the Point
Henry smelter (190 kmt-per-year) in Australia. This decision was made as management determined that the smelter
had no prospect of becoming financially viable. The shutdown of the Point Henry smelter was completed in August
2014.

Also, in March 2014, management decided to curtail the remaining capacity (62 kmt-per-year) at the Poços de Caldas
smelter and additional capacity (85 kmt-per-year) at the São Luís smelter. The curtailment of this capacity was
completed by the end of May 2014. An additional 12 kmt-per-year was curtailed at the São Luís smelter during the
remainder of 2014.

Separate from the 2013-2014 smelting capacity review described above, in June 2013, management approved the
permanent closure of the Fusina smelter (44 kmt-per-year) in Italy as the underlying conditions that led to the idling of
the smelter in 2010 had not fundamentally changed, including low aluminum prices and the lack of an economically
viable, long-term power solution. In August 2014, management approved the permanent closure of the Portovesme
smelter, which had been idle since November 2012. This decision was made because the fundamental reasons that
made the Portovesme smelter uncompetitive remained unchanged, including the lack of a viable long-term power
solution.

See Restructuring and Other Charges in Results of Operations above for a description of the associated charges related
to all of the above actions in 2015, 2014, and 2013.

In 2015, aluminum production declined by 314 kmt, mainly the result of the absence of and/or lower production at the
combined four smelters (Point Henry, São Luís, Massena East, and Poços de Caldas) impacted by the 2014 and 2015
capacity reviews and at the smelter divested in 2014 (Mt. Holly), all of which is described above.

In 2014, aluminum production decreased by 425 kmt, mostly due to lower production at the five smelters (São Luís,
Massena East, Point Henry, Baie Comeau, and Poços de Caldas) impacted by the 2013-2014 capacity review described
above.

Third-party sales for the Primary Metals segment declined 18% in 2015 compared with 2014, primarily due to a 14%
drop in average realized price, the absence of sales (approximately $585) from five smelters and a rod mill that were
closed, curtailed or divested in 2014, and lower energy sales in Brazil, due to both a decrease in energy prices and a
weaker Brazilian real. These negative impacts were slightly offset by higher volume in the remaining smelter portfolio
and higher buy/resell activity. The change in average realized price was largely attributable to a 10% lower average
LME price (on 15-day lag) and lower regional premiums, which dropped by an average of 39% in the United States
and Canada and 44% in Europe. The higher buy/resell activity was primarily related to the fulfillment of customer
orders with aluminum purchased from the smelter at the Saudi Arabia joint venture.

Third-party sales for the Primary Metals segment increased 3% in 2014 compared with 2013, mainly due to higher
energy sales in Brazil resulting from excess power due to curtailed smelter capacity, higher buy/resell activity, and a
7% increase in average realized price, mostly offset by lower volumes, including from the five smelters impacted by
the 2013 and 2014 capacity reductions. The change in average realized price was driven by higher regional premiums,
which increased by an average of 84% in the United States and Canada and 56% in Europe.

Intersegment sales for the Primary Metals segment declined 26% in 2015 compared with 2014, mainly the result of
lower demand from the midstream and downstream businesses and a decrease in average realized price. The decline
related to the midstream business was driven by the absence of shipments to four of the five rolling mills (the fifth mill

67

purchased scrap metal from third-parties) that were either divested or permanently closed in December 2014 (see
Global Rolled Products below). Intersegment sales for this segment improved 12% in 2014 compared with 2013,
principally due to an increase in average realized price, driven by higher regional premiums, and higher demand from
the midstream and downstream businesses.

ATOI for the Primary Metals segment decreased $439 in 2015 compared with 2014, primarily caused by both the
previously mentioned lower average realized aluminum price and lower energy sales, higher energy costs (mostly in
Spain as the 2014 interruptibility rights were more favorable than the 2015 structure), and an unfavorable impact
related to the curtailment of the São Luís smelter. These negative impacts were somewhat offset by net favorable
foreign currency movements due to a stronger U.S. dollar against most major currencies, net productivity
improvements, the absence of a write-off of inventory related to the permanent closure of the Portovesme, Point Henry,
and Massena East smelters ($44), and a lower equity loss related to the joint venture in Saudi Arabia, including the
absence of restart costs for one of the potlines that was previously shut down due to a period of instability.

ATOI for this segment climbed $614 in 2014 compared with 2013, principally related to a higher average realized
aluminum price; the previously mentioned energy sales in Brazil; net productivity improvements; net favorable foreign
currency movements due to a stronger U.S. dollar against all major currencies; lower costs for carbon and alumina; and
the absence of costs related to a planned maintenance outage in 2013 at a power plant in Australia. These positive
impacts were slightly offset by an unfavorable impact associated with the 2013 and 2014 capacity reductions described
above, including a write-off of inventory related to the permanent closure of the Portovesme, Point Henry, and
Massena East smelters ($44), and higher energy costs (particularly in Spain), labor, and maintenance.

In 2016, aluminum production will be approximately 450 kmt lower and third-party sales will reflect the absence of
approximately $400 both as a result of the 2015 curtailment and closure actions. Also, energy sales in Brazil will be
negatively impacted by a decline in energy prices, while net productivity improvements are anticipated.

Generally, average realized price per metric ton of aluminum includes two elements: a) the price of metal (the underlying base
metal component plus a regional premium – see the footnote to the table in Primary Metals above for a description of these two
components), and b) the conversion price, which represents the incremental price over the metal price component that is
associated with converting primary aluminum into sheet and plate. In this circumstance, the metal price component is a pass-
through to this segment’s customers with limited exception (e.g., fixed-priced contracts, certain regional premiums).

This segment represents Alcoa’s midstream operations and produces aluminum sheet and plate for a variety of end
markets. Approximately one-half of the third-party shipments in this segment consist of sheet sold directly to
customers in the packaging end market for the production of aluminum cans (beverage, food, and pet food). Seasonal
increases in can sheet sales are generally experienced in the second and third quarters of the year. This segment also
includes sheet and plate sold directly to customers and through distributors related to the aerospace, automotive,
commercial transportation, building and construction, and industrial products (mainly used in the production of
machinery and equipment and consumer durables) end markets. A small portion of this segment also produces aseptic
foil for the packaging end market. While the customer base for flat-rolled products is large, a significant amount of
sales of sheet and plate is to a relatively small number of customers. In this circumstance, the sales and costs and
expenses of this segment are transacted in the local currency of the respective operations, which are mostly the U.S.
dollar, the euro, the Russian ruble, the Brazilian real, and the British pound.

In March 2015, Alcoa completed the sale of a rolling mill located in Belaya Kalitva, Russia to a wholly-owned
subsidiary of Stupino Titanium Company. While owned by Alcoa, the operating results and assets and liabilities of the
rolling mill were included in the Global Rolled Products segment. The rolling mill generated sales of approximately
$130 in 2014 and, at the time of divestiture, had approximately 1,870 employees. See Restructuring and Other Charges
in Results of Operations above.

In February 2014, management approved the permanent shutdown of Alcoa’s two rolling mills in Australia, Point
Henry and Yennora. This decision was made due to the significant impact of excess can sheet capacity in both
Australia and Asia. The two rolling mills had a combined can sheet capacity of 200 kmt-per-year and were closed by
the end of 2014. See Restructuring and Other Charges in Results of Operations above for a description of the
associated charges.

In December 2014, Alcoa completed the sale of three rolling mills located in Spain (Alicante and Amorebieta) and
France (Castelsarrasin) to a subsidiary of Atlas Holdings LLC. While owned by Alcoa, the operating results and assets
and liabilities of the rolling mills were included in the Global Rolled Products segment. In conjunction with this
transaction, Alcoa entered into a multi-year agreement with the buyer to supply aluminum for the rolling mills. The
rolling mills combined generated sales of approximately $500 in 2013 and, at the time of divestiture, had
approximately 750 employees. See Restructuring and Other Charges in Results of Operations above.

Third-party sales for the Global Rolled Products segment declined 15% in 2015 compared with 2014, primarily driven
by the absence of sales ($1,052) from six rolling mills in Australia, Spain, Russia, and France (see above), unfavorable
pricing, mostly due to a decrease in metal prices (both LME and regional premium components), and unfavorable
foreign currency movements, mainly the result of a weaker euro, Russian ruble, and Brazilian real. These negative
impacts were somewhat offset by increased demand of the remaining rolling portfolio and favorable product mix
(automotive and aerospace versus industrial products). The volume improvement of the remaining portfolio was
largely attributable to the automotive (North America) and can sheet packaging (China) end markets, slightly offset by
lower demand in the industrial products end market.

Third-party sales for this segment improved 3% in 2014 compared with 2013, principally caused by increased demand,
somewhat offset by unfavorable price/product mix related to the packaging, aerospace, and industrial products end
markets. Volume improvements were mostly driven by the automotive and commercial transportation end markets.

ATOI for the Global Rolled Products segment decreased $1 in 2015 compared with 2014, primarily attributable to
unfavorable price/product mix, largely the result of overall pricing pressure in the global can sheet packaging end
market, and higher costs related to growth projects, including research and development as Alcoa develops and
qualifies products from a new Micromill™ production process and the ramp-up of the Tennessee automotive
expansion. These negative impacts were virtually offset by net productivity improvements across most businesses and
higher volumes of the remaining rolling portfolio, principally driven by higher demand in the automotive end market.

ATOI for this segment declined $47 in 2014 compared with 2013, mainly the result of unfavorable price/product mix
related to the packaging, aerospace, and industrial products end markets; higher input costs, including energy, labor,
maintenance, and transportation; a larger equity loss due to start-up costs related to the rolling mill at the joint venture
in Saudi Arabia; a write-off of inventory related to the decision to permanently shut down the Point Henry and Yennora
rolling mills ($9); and costs (business continuity and contract specific) related to a new labor agreement that covers
employees at three rolling mills in the United States ($4) (see COGS in Results of Operations above). These negative
impacts were partially offset by net productivity improvements across most businesses and overall higher volumes.

In 2016, demand in the automotive end market is expected to remain strong and the automotive expansion at the
Davenport, IA facility will operate at full capacity for the entire year while the automotive expansion at the Tennessee
facility will continue to ramp-up, both of which will serve the growing demand for aluminum-intensive vehicles. Also,
costs related to the ramp-up of the Tennessee facility and the previously-idled casthouse in Texarkana, TX, as well as
for preparations to run the Warrick, IN rolling facility on cold metal as a result of the planned closure of the Warrick
smelter (see Primary Metals above), are expected. Additionally, net productivity improvements are anticipated.

This segment represents a portion of Alcoa’s downstream operations and produces products that are used mostly in the
aerospace (commercial and defense), commercial transportation, and power generation end markets. Such products
include fastening systems (titanium, steel, and nickel alloys) and seamless rolled rings (mostly nickel alloys); and
investment castings (nickel super alloys, titanium, and aluminum), including airfoils and forged jet engine components
(e.g., jet engine disks), all of which are sold directly to customers and through distributors. More than 70% of the third-
party sales in this segment are from the aerospace end market. A small part of this segment also produces various
forging and extrusion metal products for the oil and gas, industrial products, automotive, and land and sea defense end
markets. Seasonal decreases in sales are generally experienced in the third quarter of the year due to the European
summer slowdown across all end markets. Generally, the sales and costs and expenses of this segment are transacted in
the local currency of the respective operations, which are mostly the U.S. dollar and the euro.

In March 2015, Alcoa completed the acquisition of an aerospace castings company, TITAL, a privately held company
with approximately 650 employees based in Germany. TITAL produces aluminum and titanium investment casting
products for the aerospace and defense end markets. In 2014, TITAL generated sales of approximately $100. The
purpose of this acquisition is to capture increasing demand for advanced jet engine components made of titanium,
establish titanium-casting capabilities in Europe, and expand existing aluminum casting capacity. The operating results
and assets and liabilities of TITAL were included within the Engineered Products and Solutions segment since the date
of acquisition.

Also in March 2015, Alcoa signed a definitive agreement to acquire RTI International Metals, Inc. (RTI), a global
supplier of titanium and specialty metal products and services for the commercial aerospace, defense, energy, and
medical device end markets. On July 23, 2015, after satisfying all customary closing conditions and receiving the
required regulatory and RTI shareholder approvals, Alcoa completed the acquisition of RTI. The purpose of this
acquisition is to expand Alcoa’s range of titanium offerings and add advanced technologies and materials, primarily
related to the aerospace end market. In 2014, RTI generated net sales of $794 and had approximately 2,600 employees.
Alcoa estimates that RTI will generate approximately $1,200 in Third-party sales by 2019. In executing its integration
plan for RTI, Alcoa expects to realize annual cost savings of approximately $100 by 2019 due to synergies derived
from procurement and productivity improvements, leveraging Alcoa’s global shared services, and driving profitable
growth. The operating results and assets and liabilities of RTI were included within the Engineered Products and
Solutions segment since the date of acquisition.

On November 19, 2014, after satisfying all customary closing conditions and receiving the required regulatory
approvals, Alcoa completed the acquisition of Firth Rixson, a global leader in aerospace jet engine components. Firth
Rixson manufactures rings, forgings, and metal products for the aerospace end market, as well as other markets
requiring highly engineered material applications. The purpose of this acquisition is to strengthen Alcoa’s aerospace
business and position the Company to capture additional aerospace growth with a broader range of high-growth, value-
add jet engine components. This business generated sales of approximately $970 in 2014 and has 13 operating facilities
in the United States, United Kingdom, Europe, and Asia employing approximately 2,400 people combined. In
executing its integration plan for Firth Rixson, Alcoa expects to realize annual cost savings of more than $100 by 2019
due to synergies derived from procurement and productivity improvements, optimizing internal metal supply, and
leveraging Alcoa’s global shared services. The operating results and assets and liabilities of Firth Rixson were included
within the Engineered Products and Solutions segment since the date of acquisition.

Third-party sales for the Engineered Products and Solutions segment improved 27% in 2015 compared with 2014,
largely attributable to the third-party sales ($1,310) of three acquired businesses (see above), primarily aerospace-
related, and higher volumes in this segment’s organic businesses, mostly related to the aerospace end market. These
positive impacts were slightly offset by unfavorable foreign currency movements, principally driven by a weaker euro.

70

Third-party sales for this segment increased 4% in 2014 compared with 2013, primarily due to higher volumes and the
acquisition of Firth Rixson ($81—see above). The higher volumes were mostly related to the aerospace (commercial)
and commercial transportation end markets, somewhat offset by lower volumes in the industrial gas turbine end
market.

ATOI for the Engineered Products and Solutions segment increased $16 in 2015 compared with 2014, principally the
result of net productivity improvements across most businesses, a positive contribution from inorganic growth, and
overall higher volumes in this segment’s organic businesses. These positive impacts were partially offset by
unfavorable price/product mix, higher costs related to growth projects, and net unfavorable foreign currency
movements, primarily related to a weaker euro.

ATOI for this segment climbed $10 in 2014 compared with 2013, mainly due to net productivity improvements across
all businesses and overall higher volumes, partially offset by higher costs, primarily labor, and unfavorable product
mix.

In 2016, demand in the commercial aerospace end market is expected to remain strong, driven by significant order
backlog. Also, third-party sales will include a positive impact due to a full year of sales related to the acquisitions of
RTI and TITAL. Additionally, net productivity improvements are anticipated while pricing pressure across all markets
is expected.

This segment represents a portion of Alcoa’s downstream operations and produces products that are used mostly in the
nonresidential building and construction and commercial transportation end markets. Such products include integrated
aluminum structural systems, architectural extrusions, and forged aluminum commercial vehicle wheels, which are
sold directly to customers and through distributors. A small part of this segment also produces aluminum products for
the industrial products end market. Generally, the sales and costs and expenses of this segment are transacted in the
local currency of the respective operations, which are mostly the U.S. dollar, the euro, and the Brazilian real.

Third-party sales for the Transportation and Construction Solutions segment decreased 7% in 2015 compared with
2014, primarily driven by unfavorable foreign currency movements, principally caused by a weaker euro and Brazilian
real, and lower volume related to the building and construction end market, somewhat offset by higher volume related
to the commercial transportation end market.

Third-party sales for this segment increased 4% in 2014 compared with 2013, mostly the result of higher volume
related to the commercial transportation and building and construction end markets, somewhat offset by lower volume
in the industrial products and market.

ATOI for the Transportation and Construction Solutions segment declined $14 in 2015 compared with 2014, mainly
due to higher costs, net unfavorable foreign currency movements, primarily related to a weaker euro and Brazilian real,
and unfavorable price/product mix. These negative impacts were mostly offset by net productivity improvements
across all businesses.

ATOI for this segment improved $13 in 2014 compared with 2013, principally attributable to net productivity
improvements across all businesses and overall higher volumes, partially offset by unfavorable product mix and higher
costs, primarily labor.

In 2016, the non-residential building and construction end market is expected to improve through growth in North
America but will be slightly offset by overall weakness in Europe. Also, North America build rates in the commercial

71

transportation end market are expected to decline while improvements in Europe are anticipated. Additionally, net
productivity improvements are anticipated.

Reconciliation of ATOI to Consolidated Net (Loss) Income Attributable to Alcoa

Items required to reconcile total segment ATOI to consolidated net (loss) income attributable to Alcoa include: the
impact of LIFO inventory accounting; metal price lag; interest expense; noncontrolling interests; corporate expense
(general administrative and selling expenses of operating the corporate headquarters and other global administrative
facilities, along with depreciation and amortization on corporate-owned assets); restructuring and other charges; and
other items, including intersegment profit eliminations, differences between tax rates applicable to the segments and
the consolidated effective tax rate, and other nonoperating items such as foreign currency transaction gains/losses and
interest income.

The following table reconciles total segment ATOI to consolidated net (loss) income attributable to Alcoa:

The significant changes in the reconciling items between total segment ATOI and consolidated net (loss) income
attributable to Alcoa for 2015 compared with 2014 consisted of:

•

•

•

•

•

•

•

a change in the Impact of LIFO, mostly due to lower prices for both aluminum, driven by both lower base
metal prices (LME) and regional premiums, and alumina (decrease in price at December 31, 2015 indexed to
December 31, 2014 compared to an increase in price at December 31, 2014 indexed to December 31, 2013);

a change in Metal price lag, the result of lower prices for aluminum;

an increase in Interest expense, principally caused by an 8% higher average debt level, which was largely
attributable to higher outstanding long-term debt due to the September 2014 issuance of $1,250 in 5.125%
Notes, somewhat offset by the absence of fees paid associated with the execution and termination of a 364-
day senior unsecured bridge term loan facility related to the then-planned acquisition of Firth Rixson ($8);

a change in Noncontrolling interests, due to the change in results of AWAC, primarily driven by improved
operating results and lower restructuring and other charges related to a number of portfolio actions (e.g.
capacity reductions and a divestiture), slightly offset by the absence of a gain on the sale of a mining interest
in Suriname ($11 was noncontrolling interest’s share);

a decline in Corporate expense, largely attributable to decreases in various expenses, including lower
acquisition costs ($13), partially offset by expenses related to the planned separation of Alcoa ($24);

an increase in Restructuring and other charges, mostly the result of a charge for legal matters in Italy,
partially offset by lower restructuring and other charges associated with a number of portfolio actions (e.g.
capacity reductions and divestitures); and

a change in Other, primarily due to a discrete income tax charge for valuation allowances on certain deferred
tax assets in the United States and Iceland ($190), write-downs of inventories related to various shutdown
and curtailment actions ($75), a net discrete income tax charge for a valuation allowance on certain deferred

72

tax assets ($34), and charges for separate environmental matters in both Norway and Italy ($15), somewhat
offset by a discrete income tax charge related to a tax rate change in both Brazil and Spain ($79) and higher
gains on various asset sales ($35).

The significant changes in the reconciling items between total segment ATOI and consolidated net income (loss)
attributable to Alcoa for 2014 compared with 2013 consisted of:

•

•

•

•

•

•

•

a change in the Impact of LIFO, mostly due to higher prices for aluminum, driven by both higher base metal
prices (LME) and regional premiums (increase in price at December 31, 2014 indexed to December 31, 2013
compared to a decrease in price at December 31, 2013 indexed to December 31, 2012), and the absence of
significant reductions in LIFO inventory quantities, which caused a partial liquidation of the lower cost LIFO
inventory base in 2013 (income of $17 in 2013);

a change in Metal price lag, the result of higher prices for aluminum;

an increase in Interest expense, primarily the result of lower capitalized interest ($28) and fees paid
associated with the execution and termination of a 364-day senior unsecured bridge term loan facility related
to the then-planned acquisition of Firth Rixson ($8), partially offset by a 3% lower average debt level and
lower amortization of debt-related costs due to the conversion of convertible notes;

a change in Noncontrolling interests, due to the change in the results of AWAC, mainly driven by
restructuring and other charges associated with both the permanent shutdown of the Point Henry smelter in
Australia and the divestiture of an ownership interest in a mining and refining joint venture in Jamaica and a
discrete income tax charge related to a tax rate change in both Brazil and Spain ($32 combined was
noncontrolling interest’s share), partially offset by improved operating results, the absence of a charge for a
legal matter ($17 was noncontrolling interest’s share), and a gain on the sale of a mining interest in Suriname
($11 was noncontrolling interest’s share);

an increase in Corporate expense, mostly related to costs associated with the acquisition of Firth Rixson
($34), partially offset by decreases in various expenses;

an increase in Restructuring and other charges, principally caused by higher costs related to decisions to
permanently shut down and/or temporarily curtail refinery, smelter and/or rolling mill capacity and a net loss
on the divestiture of four operations, partially offset by the absence of a charge for a legal matter ($322); and

a change in Other, largely attributable to the absence of a discrete income tax charge for valuation allowances
on certain deferred tax assets in Spain and the United States ($372), slightly offset by a discrete income tax
charge related to a tax rate change in both Brazil and Spain ($79).

Environmental Matters

See the Environmental Matters section of Note N to the Consolidated Financial Statements in Part II Item 8 of this
Form 10-K.

Liquidity and Capital Resources

Alcoa maintains a disciplined approach to cash management and strengthening of its balance sheet. In 2015, as has
been the focus since 2008, management initiated actions to significantly improve Alcoa’s cost structure and liquidity,
providing the Company with the ability to operate effectively. Such actions include procurement efficiencies and
overhead rationalization to reduce costs, working capital initiatives to yield significant cash improvements, and
maintaining a sustainable level of capital expenditures. In 2016, this approach will continue with the ultimate goal of
generating cash from operations that exceeds capital expenditures.

Along with the foregoing actions, cash provided from operations and financing activities is expected to be adequate to
cover Alcoa’s operational and business needs over the next 12 months. For an analysis of long-term liquidity, see
Contractual Obligations and Off-Balance Sheet Arrangements below.

73

At December 31, 2015, cash and cash equivalents of Alcoa were $1,919, of which $1,107 was held outside the United
States. Alcoa has a number of commitments and obligations related to the Company’s growth strategy in foreign
jurisdictions, resulting in the need for cash outside the United States. As such, management does not have a current
expectation of repatriating cash held in foreign jurisdictions.

Cash from Operations

Cash provided from operations in 2015 was $1,582 compared with $1,674 in 2014. The decrease of $92, or 5%, was
due to a negative change in noncurrent assets of $328, lower operating results (net (loss) income plus net add-back for
noncash transactions in earnings) and a negative change in noncurrent liabilities of $18, mostly offset by a positive
change associated with working capital of $572 and lower pension contributions of $31.

The components of the positive change in working capital were as follows:

•

•

•

•

•

•

a favorable change of $524 in receivables, mostly driven by lower customer sales as a result of closed,
divested, and curtailed locations and lower metal prices;

a positive change of $291 in inventories, largely attributable to the absence of inventory build related to the
ramp-up of automotive production at the Davenport, IA plant and customer requirements related to smelters
that have been curtailed or shut down;

a favorable change of $71 in prepaid expenses and other current assets;

a negative change of $346 in accounts payable, trade, principally the result of timing of payments;

a positive change of $14 in accrued expenses, mainly caused by a smaller payment to the United States
government due to the resolution of a legal matter (see below); and

a favorable change of $18 in taxes, including income taxes.

The unfavorable change in noncurrent assets was mostly related to a $300 prepayment made under a natural gas supply
agreement in Australia (see below).

On April 8, 2015, Alcoa’s majority-owned subsidiary, Alcoa of Australia Limited (AofA), which is part of AWAC,
secured a new 12-year gas supply agreement to power its three alumina refineries in Western Australia beginning in
July 2020. This agreement was conditional on the completion of a third-party acquisition of the related energy assets
from the then-current owner, which occurred in June 2015. The terms of AofA’s gas supply agreement require a
prepayment of $500 to be made in two installments. The first installment of $300 was made at the time of the
completion of the third-party acquisition and the second installment of $200 will be made in April 2016 (previously
was scheduled in January 2016).

Cash provided from operations in 2014 was $1,674 compared with $1,578 in 2013. The increase of $96, or 6%, was
due to higher operating results (net income plus net add-back for noncash transactions in earnings) and a positive
change in noncurrent assets of $114, mostly offset by a negative change associated with working capital of $620, a
negative change in noncurrent liabilities of $138, and higher pension contributions of $39.

The components of the negative change in working capital were as follows:

•

•

•

•

an unfavorable change of $171 in receivables, primarily related to higher customer sales;

a negative change of $380 in inventories, largely attributable to inventory build for the ramp-up of
automotive production at the Davenport, IA plant and customer requirements related to smelters that were
curtailed or shut down in 2014;

an unfavorable change of $16 in prepaid expenses and other current assets;

a negative change of $70 in accounts payable, trade, principally the result of timing of payments;

74

•

an unfavorable change of $33 in accrued expenses, mainly caused by $139 in higher payments for layoff and
other exit costs associated with restructuring actions and an $88 payment to the United States government
due to the resolution of a legal matter (see below), partially offset by the absence of $148 (€109) in payments
to the Italian government related to a November 2009 European Commission decision on electricity pricing
for certain energy-intensive industries; and

•

a positive change of $50 in taxes, including income taxes, mostly driven by higher pretax income.

The higher pension contributions of $39 were principally driven by special termination benefits of $86 for employees
affected by the 2013 shutdown of capacity at a smelter in Canada.

On August 8, 2014, the Highway and Transportation Funding Act (HATFA) was signed into law by the United States
government. HATFA, in part, provides temporary relief for employers who sponsor defined benefit pension plans
related to funding contributions under the Employee Retirement Income Security Act of 1974. Specifically, HATFA
modifies the interest rates that had been set in 2012 by the Moving Ahead for Progress in the 21st Century Act. This
relief had an immediate impact on the calculation of the then remaining funding contributions in 2014, resulting in a
reduction of $100 in minimum required pension funding.

In 2014, Alcoa World Alumina LLC, a majority-owned subsidiary of Alcoa, and Alcoa Inc. paid a combined $88 to the
United States government due to the resolution of a legal matter. Additionally, another $74 was paid in 2015 and will
be paid in each of the three subsequent years, 2016 (paid in January 2016) through 2018.

Financing Activities

Cash used for financing activities was $441 in 2015 compared with cash provided from financing activities of $2,250
in 2014 and cash used for financing activities of $679 in 2013.

The use of cash in 2015 was principally the result of $2,030 in payments on debt, mostly related to the repayment of
borrowings under certain revolving credit facilities (see below) and the repayment of convertible notes assumed in
conjunction with the acquisition of RTI (see below); $223 in dividends paid to shareholders; and $104 in net cash paid
to the noncontrolling interest in AWAC, Alumina Limited. These items were mostly offset by $1,901 in additions to
debt, virtually all of which was the result of borrowings under certain revolving credit facilities (see below).

The source of cash in 2014 was mostly driven by $2,878 in additions to debt, virtually all of which was the result of
$1,238 in net proceeds from the issuance of new senior debt securities used for the acquisition of Firth Rixson (see
below) and $1,640 in borrowings under certain revolving credit facilities (see below); net proceeds of $1,211 from the
issuance of mandatory convertible preferred stock related to the aforementioned acquisition; and $150 in proceeds
from employee exercises of 17.3 million stock options at a weighted average exercise price of $8.70 (not in millions).
These items were somewhat offset by $1,723 in payments on debt, mostly related to $1,640 for the repayment of
borrowings under certain revolving credit facilities (see below), and $161 in dividends paid to shareholders.

The use of cash in 2013 was primarily due to $2,317 in payments on debt, mainly related to $1,850 for the repayment
of borrowings under certain credit facilities (see below), a $422 early repayment of 6.00% Notes due July 2013, and
$27 for previous borrowings on the loans supporting the Estreito hydroelectric power project in Brazil; $132 in
dividends paid to shareholders; and net cash paid to noncontrolling interests of $97, most of which relates to Alumina
Limited’s share of AWAC. These items were partially offset by $1,852 in additions to debt, virtually all of which was
the result of borrowings under certain credit facilities (see below).

In July 2015, through the acquisition of RTI (see Engineered Products and Solutions in Segment Information above),
Alcoa assumed the obligation to repay two tranches of convertible debt; one tranche was due and settled in cash on
December 1, 2015 (principal amount of $115) and the other tranche is due October 15, 2019 (principal amount of
$403), unless earlier converted or purchased by Alcoa at the holder’s option upon a fundamental change. Upon
conversion of the 2019 convertible notes in accordance with their terms, holders will receive, at Alcoa’s election, cash,

75

shares of common stock (up to 27,990,966 shares), or a combination of cash and shares. On the maturity date, each
holder of outstanding notes will be entitled to receive on such date $1,000 (not in millions) in cash for each $1,000 (not
in millions) in principal amount of notes, together with accrued and unpaid interest to, but not including, the maturity
date.

On July 25, 2014, Alcoa entered into a Five-Year Revolving Credit Agreement (the “Credit Agreement”) with a
syndicate of lenders and issuers named therein. The Credit Agreement provides a $4,000 senior unsecured revolving
credit facility (the “Credit Facility”), the proceeds of which are to be used to provide working capital or for other
general corporate purposes of Alcoa. Subject to the terms and conditions of the Credit Agreement, Alcoa may from
time to time request increases in lender commitments under the Credit Facility, not to exceed $500 in aggregate
principal amount, and may also request the issuance of letters of credit, subject to a letter of credit sublimit of $1,000
under the Credit Facility.

The Credit Facility was scheduled to mature on July 25, 2019; however, on July 7, 2015, Alcoa received approval for a
one-year extension of the maturity date by the lenders and issuers that support the Credit Facility. As such, the Credit
Facility now matures on July 25, 2020, unless extended or earlier terminated in accordance with the provisions of the
Credit Agreement. Alcoa may make one additional one-year extension request during the remaining term of the Credit
Facility, subject to the lender consent requirements set forth in the Credit Agreement. Under the provisions of the
Credit Agreement, Alcoa will pay a fee of 0.25% (based on Alcoa’s long-term debt ratings as of December 31, 2015)
of the total commitment per annum to maintain the Credit Facility.

The Credit Facility is unsecured and amounts payable under it will rank pari passu with all other unsecured,
unsubordinated indebtedness of Alcoa. Borrowings under the Credit Facility may be denominated in U.S. dollars or
euros. Loans will bear interest at a base rate or a rate equal to LIBOR, plus, in each case, an applicable margin based on
the credit ratings of Alcoa’s outstanding senior unsecured long-term debt. The applicable margin on base rate loans and
LIBOR loans will be 0.50% and 1.50% per annum, respectively, based on Alcoa’s long-term debt ratings as of
December 31, 2015. Loans may be prepaid without premium or penalty, subject to customary breakage costs.

The Credit Agreement replaces Alcoa’s Five-Year Revolving Credit Agreement, dated as of July 25, 2011 (the
“Former Credit Agreement”), which was scheduled to mature on July 25, 2017. The Former Credit Agreement, which
had a total capacity of $3,750 and was undrawn, was terminated effective July 25, 2014.

The Credit Agreement includes covenants substantially similar to those in the Former Credit Agreement, including,
among others, (a) a leverage ratio, (b) limitations on Alcoa’s ability to incur liens securing indebtedness for borrowed
money, (c) limitations on Alcoa’s ability to consummate a merger, consolidation or sale of all or substantially all of its
assets, and (d) limitations on Alcoa’s ability to change the nature of its business. As of December 31, 2015, Alcoa was
in compliance with all such covenants.

The obligation of Alcoa to pay amounts outstanding under the Credit Facility may be accelerated upon the occurrence
of an “Event of Default” as defined in the Credit Agreement. Such Events of Default include, among others,
(a) Alcoa’s failure to pay the principal of, or interest on, borrowings under the Credit Facility, (b) any representation or
warranty of Alcoa in the Credit Agreement proving to be materially false or misleading, (c) Alcoa’s breach of any of its
covenants contained in the Credit Agreement, and (d) the bankruptcy or insolvency of Alcoa.

There were no amounts outstanding at December 31, 2015 and no amounts were borrowed during 2015 and 2014 under
the Credit Facility. Also, there were no amounts borrowed during 2014 related to the Former Credit Agreement.

In addition to the Credit Agreement above, Alcoa has a number of other credit agreements that provide a combined
borrowing capacity of $990, as of December 31, 2015, of which $890 is due to expire in 2016 and $100 is due to expire
in 2017. The purpose of any borrowings under these credit arrangements is to provide for working capital requirements
and for other general corporate purposes. The covenants contained in all these arrangements are the same as the Credit
Agreement (see above).

76

In 2015, 2014, and 2013, Alcoa borrowed and repaid $1,890, $1,640, and $1,850, respectively, under the respective
credit arrangements. The weighted-average interest rate and weighted-average days outstanding of the respective
borrowings during 2015, 2014, and 2013 were 1.61%, 1.54%, and 1.57%, respectively, and 69 days, 67 days, and 213
days, respectively.

In February 2014, Alcoa’s automatic shelf registration statement filed with the Securities and Exchange Commission
expired. On July 11, 2014, Alcoa filed a new shelf registration statement, which was amended on July 25, 2014 and
became effective on July 30, 2014, for up to $5,000 of securities on an unallocated basis for future issuance. As of
December 31, 2015, $2,500 in securities were issued under the new shelf registration statement.

In September 2014, Alcoa completed two public securities offerings under its shelf registration statement for (i) $1,250
of 25 million depositary shares, each representing a 1/10th interest in a share of Alcoa’s 5.375% Class B Mandatory
Convertible Preferred Stock, Series 1, par value $1 per share, liquidation preference $500 per share, and (ii) $1,250 of
5.125% Notes due 2024. The net proceeds of the offerings were used to finance the cash portion of the acquisition of
Firth Rixson (see Engineered Products and Solutions in Segment Information above).

Alcoa’s cost of borrowing and ability to access the capital markets are affected not only by market conditions but also
by the short- and long-term debt ratings assigned to Alcoa’s debt by the major credit rating agencies.

On March 9, 2015, Standard and Poor’s Ratings Services (S&P) affirmed the following ratings for Alcoa: long-term
debt at BBB- and short-term debt at A-3. Additionally, S&P changed the current outlook from negative to stable. On
September 28, 2015 S&P issued a statement that these ratings and outlook for Alcoa were not affected by Alcoa’s plan
to separate into two publicly-traded companies.

On April 16, 2015 Fitch affirmed the following ratings for Alcoa: long-term debt at BB+ and short-term debt at B.
Additionally, Fitch changed the current outlook from stable to positive. On September 30, 2015, Fitch placed these
ratings on “ratings watch positive” based on Alcoa’s plan to separate into two publicly-traded companies.

On April 30, 2015, Moody’s Investor Service (Moody’s) affirmed the following ratings for Alcoa; long-term debt at
Ba1 and short-term debt at Speculative Grade Liquidity Rating-1. Additionally, Moody’s changed the current outlook
from stable to positive. On September 28, 2015, Moody’s affirmed these ratings and changed the current outlook from
positive to developing based on Alcoa’s plan to separate into two publicly-traded companies. On January 21, 2016,
Moody’s placed Alcoa’s long-term debt rating under review and changed the current outlook from developing to rating
under review, while leaving Alcoa’s short-term debt rating unchanged.

Investing Activities

Cash used for investing activities was $1,060 in 2015 compared with $3,460 in 2014 and $1,290 in 2013.

The use of cash in 2015 was mainly due to $1,180 in capital expenditures (includes costs related to environmental
control in new and expanded facilities of $141), 38% of which related to growth projects, including the aerospace
expansion at the La Porte, IN plant, the automotive expansion at the Alcoa, TN plant, the aerospace expansion (thick
plate stretcher) at the Davenport, IA plant, the aerospace expansion (isothermal press) at the Savannah, GA plant (Firth
Rixson), and the specialty foil expansion at the Itapissuma plant in Brazil; $205 (net of cash acquired) for the
acquisition of TITAL (see Engineered Products and Solutions in Segment Information above); and $134 in additions to
investments, including the purchase of $70 in equities and fixed income securities held by Alcoa’s captive insurance
company and equity contributions of $29 related to the aluminum complex joint venture in Saudi Arabia. These items
were somewhat offset by $302 in cash acquired with RTI International Metals (see Engineered Products and Solutions
in Segment Information above); $112 in proceeds from the sale of assets and businesses, composed of three land sales
in Australia and the United States combined and post-closing adjustments related to an ownership stake in a smelter,
four rolling mills, and an ownership stake in a bauxite mine/alumina refinery divested from December 2014 through
March 2015; and $40 in sales of investments, related to the sale of $21 in equities and fixed income securities held by
Alcoa’s captive insurance company and $19 in proceeds from the sale of the remaining portion of an equity investment
in a China rolling mill.

77

The use of cash in 2014 was principally due to $2,385 (net of cash acquired) for the acquisition of Firth Rixson (see
Engineered Products and Solutions in Segment Information above); $1,219 in capital expenditures (includes costs
related to environmental control in new and expanded facilities of $129), 40% of which related to growth projects,
including the automotive expansions at the Alcoa, TN and Davenport, IA fabrication plants, the aerospace expansion at
the La Porte, IN plant, the aluminum-lithium capacity expansion at the Lafayette, IN plant, and the specialty foil
expansion at the Itapissuma plant in Brazil; and $195 in additions to investments, including equity contributions of
$120 related to the aluminum complex joint venture in Saudi Arabia and the purchase of $49 in equities and fixed
income securities held by Alcoa’s captive insurance company. These items were slightly offset by $253 in proceeds
from the sale of assets and businesses, largely attributable to the sale of an ownership stake in a bauxite mine and
refinery in Jamaica (see Alumina in Segment Information above), an ownership stake in a smelter in the United States
(see Primary Metals in Segment Information above), three rolling mills in Spain and France combined (see Global
Rolled Products in Segment Information above), and a rod plant in Canada (see Primary Metals in Segment
Information above); and $57 in sales of investments, mostly related to $42 in combined proceeds from the sale of a
mining interest in Suriname and a portion of an equity investment in a China rolling mill.

The use of cash in 2013 was primarily due to $1,193 in capital expenditures (includes costs related to environmental
control in new and expanded facilities of $143), 34% of which related to growth projects, including the automotive
expansion at the Davenport, IA fabrication plant, the aluminum-lithium capacity expansion at the Lafayette, IN plant,
and the automotive sheet expansion at the Alcoa, TN plant; and $293 in additions to investments, including equity
contributions of $171 related to the aluminum complex joint venture in Saudi Arabia and the purchase of $54 in
equities and fixed income securities held by Alcoa’s captive insurance company. These items were slightly offset by a
net change in restricted cash of $170, mostly related to the release of funds to be used for capital expenditures of the
automotive expansion at the Davenport, IA fabrication plant (see Noncash Financing and Investing Activities below).

Noncash Financing and Investing Activities

In July 2015, Alcoa purchased all outstanding shares of RTI common stock in a stock-for-stock transaction valued at
$870. As a result, Alcoa issued 87 million shares of its common stock to consummate this transaction, which was not
reflected in Alcoa’s Statement of Consolidated Cash Flows as it represents a noncash financing activity.

In early 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 (the “2014
Notes”) exercised their option to convert the 2014 Notes into 89 million shares of Alcoa common stock. The
conversion rate for the 2014 Notes was 155.4908 shares of Alcoa’s common stock per $1,000 (in full dollars) principal
amount of notes, equivalent to a conversion price of $6.43 per share. The difference between the $575 principal amount
of the 2014 Notes and the $89 par value of the issued shares increased Additional capital on Alcoa’s Consolidated
Balance Sheet. This transaction was not reflected in Alcoa’s Statement of Consolidated Cash Flows as it represents a
noncash financing activity.

In late 2014, Alcoa paid $2,995 (net of cash acquired) to acquire Firth Rixson (see Engineered Products and Solutions
in Segment Information above). A portion of this consideration was paid through the issuance of 37 million shares in
Alcoa common stock valued at $610. The issuance of common stock was not reflected in Alcoa’s Statement of
Consolidated Cash Flows as it represents a noncash investing activity.

In August 2012, Alcoa received a loan of $250 for the purpose of financing all or part of the cost of acquiring,
constructing, reconstructing, and renovating certain facilities at Alcoa’s rolling mill plant in Davenport, IA. Because
this loan can only be used for this purpose, the net proceeds of $248 were classified as restricted cash. Since restricted
cash is not part of cash and cash equivalents, this transaction was not reflected in Alcoa’s Statement of Consolidated
Cash Flows as it represents a noncash activity. As funds were expended for the project, the release of the cash was
reflected as both an inflow on the Net change in restricted cash line and an outflow on the Capital expenditures line in
the Investing Activities section of the Statement of Consolidated Cash Flows. At December 31, 2013 and 2012, Alcoa
had $13 and $171, respectively, of restricted cash remaining related to this transaction. In 2014, the remaining funds
were expended on the project.

Contractual Obligations and Off-Balance Sheet Arrangements

Contractual Obligations. Alcoa is required to make future payments under various contracts, including long-term
purchase obligations, financing arrangements, and lease agreements. Alcoa also has commitments to fund its pension

Energy-related purchase obligations consist primarily of electricity and natural gas contracts with expiration dates
ranging from 1 year to 32 years. Raw material obligations consist mostly of bauxite (relates to Alcoa’s bauxite mine
interests in Guinea and Brazil), caustic soda, alumina, aluminum fluoride, calcined petroleum coke, cathode blocks,
and various metals with expiration dates ranging from less than 1 year to 18 years. Other purchase obligations consist
principally of freight for bauxite and alumina with expiration dates ranging from 1 to 16 years. Many of these purchase
obligations contain variable pricing components, and, as a result, actual cash payments may differ from the estimates
provided in the preceding table. Operating leases represent multi-year obligations for certain land and buildings,
alumina refinery process control technology, plant equipment, vehicles, and computer equipment.

Interest related to total debt is based on interest rates in effect as of December 31, 2015 and is calculated on debt with
maturities that extend to 2042. The effect of outstanding interest rate swaps, which are accounted for as fair value
hedges, was included in interest related to total debt. As of December 31, 2015, these hedges effectively convert the
interest rate from fixed to floating on $200 of debt through 2018. As the contractual interest rates for certain debt and
interest rate swaps are variable, actual cash payments may differ from the estimates provided in the preceding table.

Estimated minimum required pension funding and postretirement benefit payments are based on actuarial estimates
using current assumptions for discount rates, long-term rate of return on plan assets, rate of compensation increases,
and health care cost trend rates, among others. The minimum required contributions for pension funding are estimated
to be $300 for 2016, $375 for 2017, $475 for 2018, $425 for 2019, and $575 for 2020. These expected pension
contributions reflect the impacts of the Pension Protection Act of 2006; the Worker, Retiree, and Employer Recovery
Act of 2008; the Moving Ahead for Progress in the 21st Century Act of 2012; the Highway and Transportation Funding

79

Act of 2014; and the Bipartisan Budget Act of 2015. Other postretirement benefit payments are expected to
approximate $220 to $230 annually for years 2016 through 2020 and $195 annually for years 2021 through 2025. Such
payments will be slightly offset by subsidy receipts related to Medicare Part D, which are estimated to be
approximately $15 to $20 annually for years 2016 through 2025. Alcoa has determined that it is not practicable to
present pension funding and other postretirement benefit payments beyond 2020 and 2025, respectively.

Layoff and other restructuring payments expected to be paid within one year primarily relate to severance costs.
Amounts scheduled to be paid beyond one year are related to ongoing site remediation work and special layoff benefit
payments.

Deferred revenue arrangements require Alcoa to deliver alumina and sheet and plate to certain customers over the
specified contract period (through 2027 for an alumina contract and through 2020 for a sheet and plate contract). While
these obligations are not expected to result in cash payments, they represent contractual obligations for which the
Company would be obligated if the specified product deliveries could not be made.

Uncertain tax positions taken or expected to be taken on an income tax return may result in additional payments to tax
authorities. The amount in the preceding table includes interest and penalties accrued related to such positions as of
December 31, 2015. The total amount of uncertain tax positions is included in the “Thereafter” column as the
Company is not able to reasonably estimate the timing of potential future payments. If a tax authority agrees with the
tax position taken or expected to be taken or the applicable statute of limitations expires, then additional payments will
not be necessary.

Obligations for Financing Activities

Total debt amounts in the preceding table represent the principal amounts of all outstanding debt, including short-term
borrowings and long-term debt. Maturities for long-term debt extend to 2042.

Alcoa has historically paid quarterly dividends on its preferred and common stock. Including dividends on preferred
stock, Alcoa paid $223 in dividends to shareholders during 2015. This amount includes dividends related to a new class
of preferred stock issued in September 2014 (see Financing Activities in Liquidity and Capital Resources above).
Because all dividends are subject to approval by Alcoa’s Board of Directors, amounts are not included in the preceding
table unless such authorization has occurred. There were $17 of preferred stock dividends approved to be paid on
January 1, 2016; however, Alcoa paid the dividends on December 31, 2015. As of December 31, 2015, there were
1,310,610,141 shares of outstanding common stock and 546,024 and 2,500,000 shares of outstanding Class A and
Class B preferred stock, respectively. The annual Class A and Class B preferred stock dividends are at the rate of $3.75
and $26.8750 per share, respectively, and the annual common stock dividend is $0.12 per share.

Obligations for Investing Activities

Capital projects in the preceding table only include amounts approved by management as of December 31, 2015.
Funding levels may vary in future years based on anticipated construction schedules of the projects. It is expected that
significant expansion projects will be funded through various sources, including cash provided from operations. Total
capital expenditures are anticipated to be approximately $1,400 in 2016.

Equity contributions represent Alcoa’s committed investment related to a joint venture in Saudi Arabia. Alcoa is a
participant in a joint venture to develop a new aluminum complex in Saudi Arabia, comprised of a bauxite mine,
alumina refinery, aluminum smelter, and rolling mill, which requires the Company to contribute approximately $1,100.
As of December 31, 2015, Alcoa has made equity contributions of $981. Based on changes to both the project’s capital
investment and equity and debt structure from the initial plans, the estimated $1,100 equity contribution may be
reduced. The timing of the amounts included in the preceding table may vary based on changes in anticipated
construction schedules of the project.

Payments related to acquisitions are based on provisions in certain acquisition agreements that state additional funds
are due to the seller from Alcoa if the businesses acquired achieve stated financial and operational thresholds. Amounts

80

are only presented in the preceding table if it is has been determined that payment is more likely than not to occur. In
connection with the acquisition of Firth Rixson (see Engineered Products and Solutions in Segment Information
above), Alcoa entered into an earn-out agreement, which states that Alcoa will make earn-out payments up to an
aggregate maximum amount of $150 through 2020. The amounts in the preceding table represent Alcoa’s best estimate
of when the payments may be made.

Off-Balance Sheet Arrangements. At December 31, 2015, Alcoa has maximum potential future payments for
guarantees issued on behalf of a third party of $478. These guarantees expire at various times between 2017 and 2024
and relate to project financing for the aluminum complex in Saudi Arabia. Alcoa also has outstanding bank guarantees
related to tax matters, outstanding debt, workers compensation, environmental obligations, energy contracts, and
customs duties, among others. The total amount committed under these guarantees, which expire at various dates
between 2016 and 2023 was $320 at December 31, 2015.

Alcoa has outstanding letters of credit primarily related to workers’ compensation, energy contracts (including $200
related to an expected April 2016 prepayment under a gas supply contract), and leasing obligations. The total amount
committed under these letters of credit, which automatically renew or expire at various dates, mostly in 2016, was $510
at December 31, 2015. Alcoa also has outstanding surety bonds primarily related to tax matters, contract performance,
workers compensation, environmental-related matters, and customs duties. The total amount committed under these
bonds, which automatically renew or expire at various dates, mostly in 2016, was $159 at December 31, 2015.

Critical Accounting Policies and Estimates

The preparation of the Consolidated Financial Statements in accordance with accounting principles generally accepted
in the United States of America requires management to make certain judgments, estimates, and assumptions regarding
uncertainties that affect the amounts reported in the Consolidated Financial Statements and disclosed in the
accompanying Notes. Areas that require significant judgments, estimates, and assumptions include accounting for
derivatives and hedging activities; environmental and litigation matters; asset retirement obligations; the testing of
goodwill, equity investments, and properties, plants, and equipment for impairment; estimating fair value of businesses
to be divested; pension plans and other postretirement benefits obligations; stock-based compensation; and income
taxes.

Management uses historical experience and all available information to make these judgments, estimates, and
assumptions, and actual results may differ from those used to prepare the Company’s Consolidated Financial
Statements at any given time. Despite these inherent limitations, management believes that Management’s Discussion
and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and
accompanying Notes provide a meaningful and fair perspective of the Company.

A summary of the Company’s significant accounting policies is included in Note A to the Consolidated Financial
Statements in Part II Item 8 of this Form 10-K. Management believes that the application of these policies on a
consistent basis enables the Company to provide the users of the Consolidated Financial Statements with useful and
reliable information about the Company’s operating results and financial condition.

Derivatives and Hedging. Derivatives are held for purposes other than trading and are part of a formally documented
risk management program. For derivatives designated as fair value hedges, Alcoa measures hedge effectiveness by
formally assessing, at least quarterly, the historical high correlation of changes in the fair value of the hedged item and
the derivative hedging instrument. For derivatives designated as cash flow hedges, Alcoa measures hedge effectiveness
by formally assessing, at least quarterly, the probable high correlation of the expected future cash flows of the hedged
item and the derivative hedging instrument. The ineffective portions of both types of hedges are recorded in sales or
other income or expense in the current period. If the hedging relationship ceases to be highly effective or it becomes
probable that an expected transaction will no longer occur, future gains or losses on the derivative instrument are
recorded in other income or expense.

Alcoa accounts for interest rate swaps related to its existing long-term debt and hedges of firm customer commitments
for aluminum as fair value hedges. As a result, the fair values of the derivatives and changes in the fair values of the

81

underlying hedged items are reported in other current and noncurrent assets and liabilities in the Consolidated Balance
Sheet. Changes in the fair values of these derivatives and underlying hedged items generally offset and are recorded
each period in sales or interest expense, consistent with the underlying hedged item.

Alcoa accounts for hedges of foreign currency exposures and certain forecasted transactions as cash flow hedges. The
fair values of the derivatives are recorded in other current and noncurrent assets and liabilities in the Consolidated
Balance Sheet. The effective portions of the changes in the fair values of these derivatives are recorded in other
comprehensive income and are reclassified to sales, cost of goods sold, or other income or expense in the period in
which earnings are impacted by the hedged items or in the period that the transaction no longer qualifies as a cash flow
hedge. These contracts cover the same periods as known or expected exposures, generally not exceeding five years.

If no hedging relationship is designated, the derivative is marked to market through earnings.

Cash flows from derivatives are recognized in the Statement of Consolidated Cash Flows in a manner consistent with
the underlying transactions.

Environmental Matters. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures
relating to existing conditions caused by past operations, which will not contribute to future revenues, are expensed.
Liabilities are recorded when remediation costs are probable and can be reasonably estimated. The liability may
include costs such as site investigations, consultant fees, feasibility studies, outside contractors, and monitoring
expenses. Estimates are generally not discounted or reduced by potential claims for recovery. Claims for recovery are
recognized as agreements are reached with third parties. The estimates also include costs related to other potentially
responsible parties to the extent that Alcoa has reason to believe such parties will not fully pay their proportionate
share. The liability is continuously reviewed and adjusted to reflect current remediation progress, prospective estimates
of required activity, and other factors that may be relevant, including changes in technology or regulations.

Litigation Matters. For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a
matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an
unfavorable outcome based on many factors such as the nature of the matter, available defenses and case strategy,
progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals
processes, and the outcome of similar historical matters, among others. Once an unfavorable outcome is deemed
probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If
an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is
recorded. With respect to unasserted claims or assessments, management must first determine that the probability that
an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability
to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there
has been a change in management’s judgment regarding the likelihood of an unfavorable outcome or the estimate of a
potential loss.

Asset Retirement Obligations. Alcoa recognizes asset retirement obligations (AROs) related to legal obligations
associated with the normal operation of Alcoa’s bauxite mining, alumina refining, and aluminum smelting facilities.
These AROs consist primarily of costs associated with spent pot lining disposal, closure of bauxite residue areas, mine
reclamation, and landfill closure. Alcoa also recognizes AROs for any significant lease restoration obligation, if
required by a lease agreement, and for the disposal of regulated waste materials related to the demolition of certain
power facilities. The fair values of these AROs are recorded on a discounted basis, at the time the obligation is
incurred, and accreted over time for the change in present value. Additionally, Alcoa capitalizes asset retirement costs
by increasing the carrying amount of the related long-lived assets and depreciating these assets over their remaining
useful life.

Certain conditional asset retirement obligations (CAROs) related to alumina refineries, aluminum smelters, and
fabrication facilities have not been recorded in the Consolidated Financial Statements due to uncertainties surrounding
the ultimate settlement date. A CARO is a legal obligation to perform an asset retirement activity in which the timing
and/or method of settlement are conditional on a future event that may or may not be within Alcoa’s control. Such

82

uncertainties exist as a result of the perpetual nature of the structures, maintenance and upgrade programs, and other
factors. At the date a reasonable estimate of the ultimate settlement date can be made, Alcoa would record an ARO for
the removal, treatment, transportation, storage and/or disposal of various regulated assets and hazardous materials such
as asbestos, underground and aboveground storage tanks, polychlorinated biphenyls, various process residuals, solid
wastes, electronic equipment waste, and various other materials. Such amounts may be material to the Consolidated
Financial Statements in the period in which they are recorded. If Alcoa was required to demolish all such structures
immediately, the estimated CARO as of December 31, 2015 ranges from less than $1 to $46 per structure (156
structures) in today’s dollars.

Goodwill. Goodwill is not amortized; instead, it is reviewed for impairment annually (in the fourth quarter) or more
frequently if indicators of impairment exist or if a decision is made to sell or exit a business. A significant amount of
judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include
deterioration in general economic conditions, negative developments in equity and credit markets, adverse changes in
the markets in which an entity operates, increases in input costs that have a negative effect on earnings and cash flows,
or a trend of negative or declining cash flows over multiple periods, among others. The fair value that could be realized
in an actual transaction may differ from that used to evaluate the impairment of goodwill.

Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating
segment or one level below an operating segment. Alcoa has ten reporting units, of which four are included in the
Engineered Products and Solutions segment and three are included in the Transportation and Construction Solutions
segment. The remaining three reporting units are the Alumina segment, the Primary Metals segment (all goodwill was
impaired in 2013—see below), and the Global Rolled Products segment. More than 70% of Alcoa’s total goodwill is
allocated to two reporting units as follows: Alcoa Fastening Systems and Rings (AFSR) ($2,232) and Alcoa Power and
Propulsion (APP) ($1,695) businesses, both of which are included in the Engineered Products and Solutions segment.
These amounts include an allocation of Corporate’s goodwill.

In November 2014, Alcoa acquired Firth Rixson (see Engineered Products and Solutions in Segment Information under
Results of Operations above), and, as a result recognized $1,801 in goodwill. This amount was allocated between the
AFSR and Alcoa Forgings and Extrusion reporting units, which is part of the Engineered Products and Solutions
segment. In March and July 2015, Alcoa acquired TITAL and RTI, respectively, (see Engineered Products and
Solutions in Segment Information under Results of Operations above) and recognized $118 and $240, respectively, in
goodwill. The goodwill amount related to TITAL was allocated to the APP reporting unit and the amount related to
RTI was allocated to Alcoa Titanium and Engineered Products, a new Alcoa reporting unit that consists solely of the
acquired RTI business and is part of the Engineered Products and Solutions segment.

In reviewing goodwill for impairment, an entity has the option to first assess qualitative factors to determine whether
the existence of events or circumstances leads to a determination that it is more likely than not (greater than 50%) that
the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative
assessment and determines that an impairment is more likely than not, the entity is then required to perform the
existing two-step quantitative impairment test (described below), otherwise no further analysis is required. An entity
also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative
impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same
whether an entity chooses to perform the qualitative assessment or proceeds directly to the two-step quantitative
impairment test.

Alcoa’s policy for its annual review of goodwill is to perform the qualitative assessment for all reporting units not
subjected directly to the two-step quantitative impairment test. Generally, management will proceed directly to the
two-step quantitative impairment test for two to three reporting units (based on facts and circumstances) during each
annual review of goodwill. This policy will result in each of the nine reporting units with goodwill being subjected to
the two-step quantitative impairment test at least once during every three-year period.

Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair
value of a reporting unit are identified (similar to impairment indicators above). These factors are then classified by the

83

type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on
current business conditions. Additionally, an assessment of the level of impact that a particular factor would have on
the estimated fair value is determined using high, medium, and low weighting. Furthermore, management considers the
results of the most recent two-step quantitative impairment test completed for a reporting unit and compares the
weighted average cost of capital (WACC) between the current and prior years for each reporting unit.

During the 2015 annual review of goodwill, management performed the qualitative assessment for seven reporting
units, the Alumina segment, the four reporting units in the Engineered Products and Solutions segment, including
AFSR and APP, and two reporting units in the Transportation and Construction Solutions segment. Management
concluded that it was not more likely than not that the estimated fair values of the seven reporting units were less than
their carrying values. As such, no further analysis was required.

Under the two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair
value of each reporting unit to its carrying value, including goodwill. Alcoa uses a discounted cash flow (DCF) model
to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted
cash flows are the best indicator of such fair value. A number of significant assumptions and estimates are involved in
the application of the DCF model to forecast operating cash flows, including markets and market share, sales volumes
and prices, production costs, tax rates, capital spending, discount rate, and working capital changes. Most of these
assumptions vary significantly among the reporting units. Cash flow forecasts are generally based on approved
business unit operating plans for the early years and historical relationships in later years. The betas used in calculating
the individual reporting units’ WACC rate are estimated for each business with the assistance of valuation experts.

In the event the estimated fair value of a reporting unit per the DCF model is less than the carrying value, additional
analysis would be required. The additional analysis would compare the carrying amount of the reporting unit’s
goodwill with the implied fair value of that goodwill, which may involve the use of valuation experts. The implied fair
value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the
assets and liabilities of that unit as if the reporting unit was acquired in a business combination and the fair value of the
reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an
impairment loss equal to such excess would be recognized, which could significantly and adversely impact reported
results of operations and shareholders’ equity.

During the 2015 annual review of goodwill, management proceeded directly to the two-step quantitative impairment
test for two reporting units as follows: Global Rolled Products segment and the soft alloys extrusion business in Brazil
(hereafter “SAE”), which is included in the Transportation and Construction Solutions segment. The estimated fair
value of the Global Rolled Products segment was substantially in excess of its respective carrying value, resulting in no
impairment. For SAE, the estimated fair value as determined by the DCF model was lower than the associated carrying
value. As a result, management performed the second step of the impairment analysis in order to determine the implied
fair value of the SAE reporting unit’s goodwill. The results of the second-step analysis showed that the implied fair
value of the goodwill was zero. Therefore, in the fourth quarter of 2015, Alcoa recorded a goodwill impairment of $25.
The impairment of the SAE goodwill resulted from headwinds from the recent downturn in the Brazilian economy and
the continued erosion of gross margin despite the execution of cost reduction strategies. As a result of the goodwill
impairment, there is no goodwill remaining for the SAE reporting unit.

Goodwill impairment tests in prior years indicated that goodwill was not impaired for any of the Company’s reporting
units, except for the Primary Metals segment in 2013 (see below), and there were no triggering events since that time
that necessitated an impairment test.

In 2013, for Primary Metals, the estimated fair value as determined by the DCF model was lower than the associated
carrying value. As a result, management performed the second step of the impairment analysis in order to determine
the implied fair value of Primary Metals’ goodwill. The results of the second-step analysis showed that the implied fair
value of goodwill was zero. Therefore, in the fourth quarter of 2013, Alcoa recorded a goodwill impairment of $1,731
($1,719 after noncontrolling interest). As a result of the goodwill impairment, there is no goodwill remaining for the
Primary Metals reporting unit.

84

The impairment of Primary Metals’ goodwill resulted from several causes: the prolonged economic downturn; a
disconnect between industry fundamentals and pricing that has resulted in lower metal prices; and the increased cost of
alumina, a key raw material, resulting from expansion of the Alumina Price Index throughout the industry. All of these
factors, exacerbated by increases in discount rates, continue to place significant downward pressure on metal prices and
operating margins, and the resulting estimated fair value, of the Primary Metals business. As a result, management
decreased the near-term and long-term estimates of the operating results and cash flows utilized in assessing Primary
Metals’ goodwill for impairment. The valuation of goodwill for the second step of the goodwill impairment analysis is
considered a level 3 fair value measurement, which means that the valuation of the assets and liabilities reflect
management’s own judgments regarding the assumptions market participants would use in determining the fair value
of the assets and liabilities.

Equity Investments. Alcoa invests in a number of privately-held companies, primarily through joint ventures and
consortia, which are accounted for on the equity method. The equity method is applied in situations where Alcoa has
the ability to exercise significant influence, but not control, over the investee. Management reviews equity investments
for impairment whenever certain indicators are present suggesting that the carrying value of an investment is not
recoverable. This analysis requires a significant amount of judgment from management to identify events or
circumstances indicating that an equity investment is impaired. The following items are examples of impairment
indicators: significant, sustained declines in an investee’s revenue, earnings, and cash flow trends; adverse market
conditions of the investee’s industry or geographic area; the investee’s ability to continue operations measured by
several items, including liquidity; and other factors. Once an impairment indicator is identified, management uses
considerable judgment to determine if the impairment is other than temporary, in which case the equity investment is
written down to its estimated fair value. An impairment that is other than temporary could significantly and adversely
impact reported results of operations.

Properties, Plants, and Equipment. Properties, plants, and equipment are reviewed for impairment whenever events
or changes in circumstances indicate that the carrying amount of such assets (asset group) may not be recoverable.
Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the operations
related to the assets (asset group) to their carrying amount. An impairment loss would be recognized when the carrying
amount of the assets (asset group) exceeds the estimated undiscounted net cash flows. The amount of the impairment
loss to be recorded is calculated as the excess of the carrying value of the assets (asset group) over their fair value, with
fair value determined using the best information available, which generally is a DCF model. The determination of what
constitutes an asset group, the associated estimated undiscounted net cash flows, and the estimated useful lives of
assets also require significant judgments.

Discontinued Operations and Assets Held For Sale. The fair values of all businesses to be divested are estimated
using accepted valuation techniques such as a DCF model, valuations performed by third parties, earnings multiples, or
indicative bids, when available. A number of significant estimates and assumptions are involved in the application of
these techniques, including the forecasting of markets and market share, sales volumes and prices, costs and expenses,
and multiple other factors. Management considers historical experience and all available information at the time the
estimates are made; however, the fair value that is ultimately realized upon the divestiture of a business may differ
from the estimated fair value reflected in the Consolidated Financial Statements.

Pension and Other Postretirement Benefits. Liabilities and expenses for pension and other postretirement benefits
are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used
to discount the future estimated liability, the expected long-term rate of return on plan assets, and several assumptions
relating to the employee workforce (salary increases, health care cost trend rates, retirement age, and mortality).

The interest rate used to discount future estimated liabilities is determined using a Company-specific yield curve model
(above-median) developed with the assistance of an external actuary. The cash flows of the plans’ projected benefit
obligations are discounted using a single equivalent rate derived from yields on high quality corporate bonds, which
represent a broad diversification of issuers in various sectors, including finance and banking, consumer products,
transportation, insurance, and pharmaceutical, among others. The yield curve model parallels the plans’ projected cash
flows, which have an average duration of 10 years, and the underlying cash flows of the bonds included in the model

85

exceed the cash flows needed to satisfy the Company’s plans’ obligations multiple times. In 2015, 2014, and 2013, the
discount rate used to determine benefit obligations for U.S. pension and other postretirement benefit plans was 4.29%,
4.00%, and 4.80%, respectively. The impact on the liabilities of a change in the discount rate of 1/4 of 1% would be
approximately $430 and either a charge or credit of approximately $15 to after-tax earnings in the following year.

In conjunction with the annual measurement of the funded status of Alcoa’s pension and other postretirement benefit
plans at December 31, 2015, management elected to change the manner in which the interest cost component of net
periodic benefit cost will be determined in 2016 and beyond. Previously, the interest cost component was determined
by multiplying the single equivalent rate described above and the aggregate discounted cash flows of the plans’
projected benefit obligations. Under the new methodology, the interest cost component will be determined by
aggregating the product of the discounted cash flows of the plans’ projected benefit obligations for each year and an
individual spot rate (referred to as the “spot rate” approach). This change will result in a lower interest cost component
of net periodic benefit cost under the new methodology compared to the previous methodology of approximately $100
($65 after-tax) in 2016. Management believes this new methodology, which represents a change in an accounting
estimate, is a better measure of the interest cost as each year’s cash flows are specifically linked to the interest rates of
bond payments in the same respective year.

The expected long-term rate of return on plan assets is generally applied to a five-year market-related value of plan
assets (a four-year average or the fair value at the plan measurement date is used for certain non-U.S. plans). The
process used by management to develop this assumption is one that relies on a combination of historical asset return
information and forward-looking returns by asset class. As it relates to historical asset return information, management
focuses on the annual, 10-year moving, and 20-year moving averages when developing this assumption. Management
also incorporates expected future returns on current and planned asset allocations using information from various
external investment managers and consultants, as well as management’s own judgment.

For 2015, 2014, and 2013, management used 7.75%, 8.00%, and 8.50% as its expected long-term rate of return, which
was based on the prevailing and planned strategic asset allocations, as well as estimates of future returns by asset class.
These rates fell within the respective range of the 20-year moving average of actual performance and the expected
future return developed by asset class. In 2015, the decrease of 25 basis points in the expected long-term rate of return
was due to a decrease in the 20-year moving average of actual performance. For 2016, management anticipates that
7.75% will be the expected long-term rate of return.

A change in the assumption for the expected long-term rate of return on plan assets of 1/4 of 1% would impact after-tax
earnings by approximately $20 for 2015.

During 2014, an independent U.S. organization that publishes standard mortality rates based on statistical analysis and
studies issued updated mortality tables. The rates within these standard tables are used by actuaries as one of the many
assumptions when measuring a company’s projected benefit obligation for pension and other postretirement benefit
plans. The funded status of all of Alcoa’s pension and other postretirement benefit plans are measured as of
December 31 each calendar year. During the measurement process at the end of 2014, Alcoa, with the assistance of an
external actuary, considered the rates in the new mortality tables, along with specific data related to Alcoa’s retiree
population, to develop the mortality-related assumptions used to measure the benefit obligation of various U.S. benefit
plans. As a result, Alcoa recognized a charge of approximately $100 ($65 after-tax) in other comprehensive loss related
to the updated mortality assumptions.

In 2015, a net charge of $10 (after-tax and noncontrolling interest) was recorded in other comprehensive loss, primarily
due to the unfavorable performance of the plan assets, which was mostly offset by the amortization of actuarial losses
and a 30 basis point increase in the discount rate. In 2014, a net charge of $69 (after-tax and noncontrolling interest)
was recorded in other comprehensive loss, primarily due to an 80 basis point decrease in the discount rate and a change
in the mortality assumption (see above), which was mostly offset by the favorable performance of the plan assets and
the amortization of actuarial losses. In 2013, a net benefit of $531 (after-tax and noncontrolling interest) was recorded
in other comprehensive loss, primarily due to a 65 basis point increase in the discount rate and the amortization of
actuarial losses.

86

Stock-based Compensation. Alcoa recognizes compensation expense for employee equity grants using the non-
substantive vesting period approach, in which the expense (net of estimated forfeitures) is recognized ratably over the
requisite service period based on the grant date fair value. The fair value of new stock options is estimated on the date
of grant using a lattice-pricing model. Determining the fair value of stock options at the grant date requires judgment,
including estimates for the average risk-free interest rate, dividend yield, volatility, and exercise behavior. These
assumptions may differ significantly between grant dates because of changes in the actual results of these inputs that
occur over time.

As part of Alcoa’s stock-based compensation plan design, individuals who are retirement-eligible have a six-month
requisite service period in the year of grant. As a result, a larger portion of expense will be recognized in the first half
of each year for these retirement-eligible employees. Compensation expense recorded in 2015, 2014, and 2013 was $92
($61 after-tax), $87 ($58 after-tax), and $71 ($48 after-tax), respectively. Of these amounts, $17, $15, and $14 in 2015,
2014, and 2013, respectively, pertains to the acceleration of expense related to retirement-eligible employees.

Most plan participants can choose whether to receive their award in the form of stock options, stock awards, or a
combination of both. This choice is made before the grant is issued and is irrevocable.

Income Taxes. The provision for income taxes is determined using the asset and liability approach of accounting for
income taxes. Under this approach, the provision for income taxes represents income taxes paid or payable (or received
or receivable) for the current year plus the change in deferred taxes during the year. Deferred taxes represent the future
tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid, and result
from differences between the financial and tax bases of Alcoa’s assets and liabilities and are adjusted for changes in tax
rates and tax laws when enacted.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50%) that
a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential
sources of taxable income, including income available in carryback periods, future reversals of taxable temporary
differences, projections of taxable income, and income from tax planning strategies, as well as all available positive
and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of
future profitability within the carryforward period, including from tax planning strategies, and Alcoa’s experience with
similar operations. Existing favorable contracts and the ability to sell products into established markets are additional
positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or
carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing
projections of income. Deferred tax assets for which no valuation allowance is recorded may not be realized upon
changes in facts and circumstances, resulting in a future charge to establish a valuation allowance. Existing valuation
allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is
more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any,
is released. Deferred tax assets and liabilities are also re-measured to reflect changes in underlying tax rates due to law
changes and the granting and lapse of tax holidays.

In 2013, Alcoa recognized a $372 discrete income tax charge for valuation allowances on certain deferred tax assets in
Spain and the United States. Of this amount, a $237 valuation allowance was established on the full value of the
deferred tax assets related to a Spanish consolidated tax group. These deferred tax assets have an expiration period
ranging from 2016 (for certain credits) to an unlimited life (for operating losses). After weighing all available positive
and negative evidence, as described above, management determined that it was no longer more likely than not that
Alcoa will realize the tax benefit of these deferred tax assets. This was mainly driven by a decline in the outlook of the
Primary Metals business (2013 realized prices were the lowest since 2009) combined with prior year cumulative losses
of the Spanish consolidated tax group. During 2014, the underlying value of the deferred tax assets decreased due to a
remeasurement as a result of the enactment of new tax rates in Spain beginning in 2015 (see Income Taxes in Earnings
Summary under Results of Operations above), the sale of a member of the Spanish consolidated tax group, and a
change in foreign currency exchange rates. As a result, the valuation allowance decreased by the same amount. At
December 31, 2015, the amount of the valuation allowance was $149. This valuation allowance was reevaluated as of
December 31, 2015, and no change to the allowance was deemed necessary based on all available evidence. The need

87

for this valuation allowance will be assessed on a continuous basis in future periods and, as a result, a portion or all of
the allowance may be reversed based on changes in facts and circumstances.

The remaining $135 recognized in 2013 relates to a valuation allowance established on a portion of available foreign
tax credits in the United States. These credits can be carried forward for 10 years, and have an expiration period
ranging from 2016 to 2023 as of December 31, 2013 (2016 to 2025 as of December 31, 2015). After weighing all
available positive and negative evidence, as described above, management determined that it was no longer more likely
than not that Alcoa will realize the full tax benefit of these foreign tax credits. This was primarily due to lower foreign
sourced taxable income after consideration of tax planning strategies and after the inclusion of earnings from foreign
subsidiaries projected to be distributable as taxable foreign dividends. This valuation allowance was reevaluated as of
December 31, 2015, and due to reductions in foreign sourced taxable income, a $134 discrete income tax charge was
recognized. Additionally, $15 of foreign tax credits expired at the end of 2015 resulting in a corresponding decrease to
the valuation allowance. At December 31, 2015, the amount of the valuation allowance was $254. The need for this
valuation allowance will be assessed on a continuous basis in future periods and, as a result, an increase or decrease to
this allowance may result based on changes in facts and circumstances.

In 2015, Alcoa recognized an additional $141 discrete income tax charge for valuation allowances on certain deferred
tax assets in Iceland and Suriname. Of this amount, an $85 valuation allowance was established on the full value of the
deferred tax assets in Suriname, which were related mostly to employee benefits and tax loss carryforwards. These
deferred tax assets have an expiration period ranging from 2016 to 2022. The remaining $56 charge relates to a
valuation allowance established on a portion of the deferred tax assets recorded in Iceland. These deferred tax assets
have an expiration period ranging from 2017 to 2023. After weighing all available positive and negative evidence, as
described above, management determined that it was no longer more likely than not that Alcoa will realize the tax
benefit of either of these deferred tax assets. This was mainly driven by a decline in the outlook of the Primary Metals
business, combined with prior year cumulative losses and a short expiration period. The need for this valuation
allowance will be assessed on a continuous basis in future periods and, as a result, a portion or all of the allowance may
be reversed based on changes in facts and circumstances.

Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such benefits
meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively
settled, which means that the statute of limitation has expired or the appropriate taxing authority has completed their
examination even though the statute of limitations remains open. Interest and penalties related to uncertain tax positions are
recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties
would be applicable under relevant tax law until such time that the related tax benefits are recognized.

Related Party Transactions

Alcoa buys products from and sells products to various related companies, consisting of entities in which Alcoa retains
a 50% or less equity interest, at negotiated prices between the two parties. These transactions were not material to the
financial position or results of operations of Alcoa for all periods presented.

Management’s Report on Financial Statements and Practices

Management’s Reports to Alcoa Shareholders

The accompanying Consolidated Financial Statements of Alcoa Inc. and its subsidiaries (the “Company”) were prepared by
management, which is responsible for their integrity and objectivity. The statements were prepared in accordance with accounting
principles generally accepted in the United States of America and include amounts that are based on management’s best judgments
and estimates. The other financial information included in the annual report is consistent with that in the financial statements.

Management also recognizes its responsibility for conducting the Company’s affairs according to the highest standards of personal
and corporate conduct. This responsibility is characterized and reflected in key policy statements issued from time to time regarding,
among other things, conduct of its business activities within the laws of the host countries in which the Company operates and
potentially conflicting outside business interests of its employees. The Company maintains a systematic program to assess
compliance with these policies.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In
order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act,
management has conducted an assessment, including testing, using the criteria in Internal Control—Integrated Framework (2013),
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s system of 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. The
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 accounting principles generally accepted in the United States of America, and that receipts and expenditures of the
Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on the assessment, management has concluded that the Company maintained effective internal control over financial reporting
as of December 31, 2015, based on criteria in Internal Control—Integrated Framework (2013) issued by the COSO.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2015 has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein.

RTI International Metals has been excluded from management’s assessment of internal control over financial reporting as of
December 31, 2015, as it was acquired by the Company in a purchase business combination in July 2015. RTI International Metals is a
100% owned subsidiary whose total assets (excluding goodwill and intangible assets) and total sales represent 5% and 1%,
respectively, of the related consolidated financial statement amounts of the Company as of and for the year ended December 31, 2015.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Alcoa Inc.

In our opinion, the accompanying consolidated balance sheet and the related statements of consolidated operations,
consolidated comprehensive loss, changes in consolidated equity, and consolidated cash flows present fairly, in all
material respects, the financial position of Alcoa Inc. and its subsidiaries (the “Company”) at December 31, 2015 and
2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31,
2015 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion,
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31,
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 accompanying Management’s Report on Internal
Control over Financial Reporting. 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.

As disclosed in Recently Adopted Accounting Guidance in Note A to the consolidated financial statements, the
Company changed the classification of current deferred income tax assets and liabilities in the consolidated balance
sheet at December 31, 2015 and 2014.

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
accounting principles generally accepted in the United States of America. 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
accounting principles generally accepted in the United States of America, and that receipts and expenditures of the
company are being made only in accordance with authorizations of management and directors of the company; and
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in the accompanying Management’s Report on Internal Control over Financial Reporting, management
has excluded RTI International Metals from its assessment of internal control over financial reporting as of
December 31, 2015 because it was acquired by the Company in a purchase business combination in July 2015. We
have also excluded RTI International Metals from our audit of internal control over financial reporting. RTI
International Metals is a 100% owned subsidiary whose total assets (excluding goodwill and intangible assets) and total
sales represent 5% and 1%, respectively, of the related consolidated financial statement amounts of the Company as of
and for the year ended December 31, 2015.

Notes to the Consolidated Financial Statements
(dollars in millions, except per-share amounts)

A. Summary of Significant Accounting Policies

Basis of Presentation. The Consolidated Financial Statements of Alcoa Inc. and subsidiaries (“Alcoa” or the
“Company”) are prepared in conformity with accounting principles generally accepted in the United States of America
(GAAP) and require management to make certain judgments, estimates, and assumptions. These may affect the
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the
financial statements. They also may affect the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates upon subsequent resolution of identified matters. Certain prior year
amounts have been reclassified to conform to the current year presentation.

Principles of Consolidation. The Consolidated Financial Statements include the accounts of Alcoa and companies in
which Alcoa has a controlling interest. Intercompany transactions have been eliminated. The equity method of
accounting is used for investments in affiliates and other joint ventures over which Alcoa has significant influence but
does not have effective control. Investments in affiliates in which Alcoa cannot exercise significant influence are
accounted for on the cost method.

Management also evaluates whether an Alcoa entity or interest is a variable interest entity and whether Alcoa is the
primary beneficiary. Consolidation is required if both of these criteria are met. Alcoa does not have any variable
interest entities requiring consolidation.

Related Party Transactions. Alcoa buys products from and sells products to various related companies, consisting of
entities in which Alcoa retains a 50% or less equity interest, at negotiated prices between the two parties. These
transactions were not material to the financial position or results of operations of Alcoa for all periods presented.

Cash Equivalents. Cash equivalents are highly liquid investments purchased with an original maturity of three months
or less.

Inventory Valuation. Inventories are carried at the lower of cost or market, with cost for approximately half of U.S.
and Canadian inventories determined under the last-in, first-out (LIFO) method. The cost of other inventories is
principally determined under the average-cost method.

Properties, Plants, and Equipment. Properties, plants, and equipment are recorded at cost. Depreciation is recorded
principally on the straight-line method at rates based on the estimated useful lives of the assets. For greenfield assets,
which refer to the construction of new assets on undeveloped land, the units of production method is used to record
depreciation. These assets require a significant period (generally greater than one-year) to ramp-up to full production
capacity. As a result, the units of production method is deemed a more systematic and rational method for recognizing
depreciation on these assets. Depreciation is recorded on temporarily idled facilities until such time management
approves a permanent shutdown. The following table details the weighted-average useful lives of structures and
machinery and equipment by reporting segment (numbers in years):

Gains or losses from the sale of assets are generally recorded in other income or expenses (see policy below for assets
classified as held for sale and discontinued operations). Repairs and maintenance are charged to expense as incurred.
Interest related to the construction of qualifying assets is capitalized as part of the construction costs.

Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of such assets (asset group) may not be recoverable. Recoverability of assets is determined by
comparing the estimated undiscounted net cash flows of the operations related to the assets (asset group) to their
carrying amount. An impairment loss would be recognized when the carrying amount of the assets (asset group)
exceeds the estimated undiscounted net cash flows. The amount of the impairment loss to be recorded is calculated as
the excess of the carrying value of the assets (asset group) over their fair value, with fair value determined using the
best information available, which generally is a discounted cash flow (DCF) model. The determination of what
constitutes an asset group, the associated estimated undiscounted net cash flows, and the estimated useful lives of
assets also require significant judgments.

Mineral Rights. Alcoa recognizes mineral rights upon specific acquisitions of land that include such underlying rights,
primarily in Jamaica (in December 2014, Alcoa divested its ownership stake in the joint venture in Jamaica—see Note
F). This land is purchased for the sole purpose of mining bauxite. The underlying bauxite reserves are known at the
time of acquisition based on associated drilling and analysis and are considered to be proven reserves. The acquisition
cost of the land and mineral rights are amortized as the bauxite is produced based on the level of minable tons
determined at the time of purchase. Mineral rights are included in Properties, plants, and equipment on the
accompanying Consolidated Balance Sheet.

Deferred Mining Costs. Alcoa recognizes deferred mining costs during the development stage of a mine life cycle.
Such costs include the construction of access and haul roads, detailed drilling and geological analysis to further define
the grade and quality of the known bauxite, and overburden removal costs. These costs relate to sections of the related
mines where Alcoa is either currently extracting bauxite or is preparing for production in the near term. These sections
are outlined and planned incrementally and generally are mined over periods ranging from one to five years, depending
on mine specifics. The amount of geological drilling and testing necessary to determine the economic viability of the
bauxite deposit being mined is such that the reserves are considered to be proven, and the mining costs are amortized
based on this level of reserves. Deferred mining costs are included in Other noncurrent assets on the accompanying
Consolidated Balance Sheet.

Goodwill and Other Intangible Assets. Goodwill is not amortized; instead, it is reviewed for impairment annually (in
the fourth quarter) or more frequently if indicators of impairment exist or if a decision is made to sell or exit a business.
A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such
indicators may include deterioration in general economic conditions, negative developments in equity and credit
markets, adverse changes in the markets in which an entity operates, increases in input costs that have a negative effect
on earnings and cash flows, or a trend of negative or declining cash flows over multiple periods, among others. The fair
value that could be realized in an actual transaction may differ from that used to evaluate the impairment of goodwill.

Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating
segment or one level below an operating segment. Alcoa has ten reporting units, of which four are included in the
Engineered Products and Solutions segment and three are included in the Transportation and Construction Solutions
segment. The remaining three reporting units are the Alumina segment, the Primary Metals segment (all goodwill was
impaired in 2013—see below), and the Global Rolled Products segment. More than 70% of Alcoa’s total goodwill is
allocated to two reporting units as follows: Alcoa Fastening Systems and Rings (AFSR) ($2,232) and Alcoa Power and
Propulsion (APP) ($1,695) businesses, both of which are included in the Engineered Products and Solutions segment.
These amounts include an allocation of Corporate’s goodwill.

In November 2014, Alcoa acquired Firth Rixson (see Note F), and, as a result recognized $1,801 in goodwill. This
amount was allocated between the AFSR and Alcoa Forgings and Extrusion reporting units, which is part of the
Engineered Products and Solutions segment. In March and July 2015, Alcoa acquired TITAL and RTI, respectively,

(see Note F) and recognized $118 and $240, respectively, in goodwill. The goodwill amount related to TITAL was
allocated to the APP reporting unit and the amount related to RTI was allocated to Alcoa Titanium and Engineered
Products, a new Alcoa reporting unit that consists solely of the acquired RTI business and is part of the Engineered
Products and Solutions segment.

In reviewing goodwill for impairment, an entity has the option to first assess qualitative factors to determine whether
the existence of events or circumstances leads to a determination that it is more likely than not (greater than 50%) that
the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative
assessment and determines that an impairment is more likely than not, the entity is then required to perform the
existing two-step quantitative impairment test (described below), otherwise no further analysis is required. An entity
also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative
impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same
whether an entity chooses to perform the qualitative assessment or proceeds directly to the two-step quantitative
impairment test.

Alcoa’s policy for its annual review of goodwill is to perform the qualitative assessment for all reporting units not
subjected directly to the two-step quantitative impairment test. Generally, management will proceed directly to the
two-step quantitative impairment test for two to three reporting units (based on facts and circumstances) during each
annual review of goodwill. This policy will result in each of the nine reporting units with goodwill being subjected to
the two-step quantitative impairment test at least once during every three-year period.

Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair
value of a reporting unit are identified (similar to impairment indicators above). These factors are then classified by the
type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on
current business conditions. Additionally, an assessment of the level of impact that a particular factor would have on
the estimated fair value is determined using high, medium, and low weighting. Furthermore, management considers the
results of the most recent two-step quantitative impairment test completed for a reporting unit and compares the
weighted average cost of capital (WACC) between the current and prior years for each reporting unit.

During the 2015 annual review of goodwill, management performed the qualitative assessment for seven reporting
units, the Alumina segment, the four reporting units in the Engineered Products and Solutions segment, including
AFSR and APP, and two reporting units in the Transportation and Construction Solutions segment. Management
concluded that it was not more likely than not that the estimated fair values of the seven reporting units were less than
their carrying values. As such, no further analysis was required.

Under the two-step quantitative impairment test, the evaluation of impairment involves comparing the current fair
value of each reporting unit to its carrying value, including goodwill. Alcoa uses a DCF model to estimate the current
fair value of its reporting units when testing for impairment, as management believes forecasted cash flows are the best
indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the
DCF model to forecast operating cash flows, including markets and market share, sales volumes and prices, production
costs, tax rates, capital spending, discount rate, and working capital changes. Most of these assumptions vary
significantly among the reporting units. Cash flow forecasts are generally based on approved business unit operating
plans for the early years and historical relationships in later years. The betas used in calculating the individual reporting
units’ WACC rate are estimated for each business with the assistance of valuation experts.

In the event the estimated fair value of a reporting unit per the DCF model is less than the carrying value, additional
analysis would be required. The additional analysis would compare the carrying amount of the reporting unit’s
goodwill with the implied fair value of that goodwill, which may involve the use of valuation experts. The implied fair
value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the
assets and liabilities of that unit as if the reporting unit was acquired in a business combination and the fair value of the
reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an
impairment loss equal to such excess would be recognized, which could significantly and adversely impact reported
results of operations and shareholders’ equity.

98

During the 2015 annual review of goodwill, management proceeded directly to the two-step quantitative impairment
test for two reporting units as follows: Global Rolled Products segment and the soft alloys extrusion business in Brazil
(hereafter “SAE”), which is included in the Transportation and Construction Solutions segment. The estimated fair
value of the Global Rolled Products segment was substantially in excess of its respective carrying value, resulting in no
impairment. For SAE, the estimated fair value as determined by the DCF model was lower than the associated carrying
value. As a result, management performed the second step of the impairment analysis in order to determine the implied
fair value of the SAE reporting unit’s goodwill. The results of the second-step analysis showed that the implied fair
value of the goodwill was zero. Therefore, in the fourth quarter of 2015, Alcoa recorded a goodwill impairment of $25.
The impairment of the SAE goodwill resulted from headwinds from the recent downturn in the Brazilian economy and
the continued erosion of gross margin despite the execution of cost reduction strategies. As a result of the goodwill
impairment, there is no goodwill remaining for the SAE reporting unit.

Goodwill impairment tests in prior years indicated that goodwill was not impaired for any of the Company’s reporting
units, except for the Primary Metals segment in 2013 (see below), and there were no triggering events since that time
that necessitated an impairment test.

In 2013, for Primary Metals, the estimated fair value as determined by the DCF model was lower than the associated
carrying value. As a result, management performed the second step of the impairment analysis in order to determine
the implied fair value of Primary Metals’ goodwill. The results of the second-step analysis showed that the implied fair
value of goodwill was zero. Therefore, in the fourth quarter of 2013, Alcoa recorded a goodwill impairment of $1,731
($1,719 after noncontrolling interest). As a result of the goodwill impairment, there is no goodwill remaining for the
Primary Metals reporting unit.

The impairment of Primary Metals’ goodwill resulted from several causes: the prolonged economic downturn; a
disconnect between industry fundamentals and pricing that has resulted in lower metal prices; and the increased cost of
alumina, a key raw material, resulting from expansion of the Alumina Price Index throughout the industry. All of these
factors, exacerbated by increases in discount rates, continue to place significant downward pressure on metal prices and
operating margins, and the resulting estimated fair value, of the Primary Metals business. As a result, management
decreased the near-term and long-term estimates of the operating results and cash flows utilized in assessing Primary
Metals’ goodwill for impairment. The valuation of goodwill for the second step of the goodwill impairment analysis is
considered a level 3 fair value measurement, which means that the valuation of the assets and liabilities reflect
management’s own judgments regarding the assumptions market participants would use in determining the fair value
of the assets and liabilities.

Intangible assets with indefinite useful lives are not amortized while intangible assets with finite useful lives are
amortized generally on a straight-line basis over the periods benefited. The following table details the weighted-

Equity Investments. Alcoa invests in a number of privately-held companies, primarily through joint ventures and
consortia, which are accounted for using the equity method. The equity method is applied in situations where
Alcoa has the ability to exercise significant influence, but not control, over the investee. Management reviews
equity investments for impairment whenever certain indicators are present suggesting that the carrying value of
an investment is not recoverable. This analysis requires a significant amount of judgment from management to
identify events or circumstances indicating that an equity investment is impaired. The following items are
examples of impairment indicators: significant, sustained declines in an investee’s revenue, earnings, and cash

99

flow trends; adverse market conditions of the investee’s industry or geographic area; the investee’s ability to
continue operations measured by several items, including liquidity; and other factors. Once an impairment
indicator is identified, management uses considerable judgment to determine if the impairment is other than
temporary, in which case the equity investment is written down to its estimated fair value. An impairment that is
other than temporary could significantly and adversely impact reported results of operations.

Revenue Recognition. Alcoa recognizes revenue when title, ownership, and risk of loss pass to the customer, all of
which occurs upon shipment or delivery of the product and is based on the applicable shipping terms. The shipping
terms vary across all businesses and depend on the product, the country of origin, and the type of transportation (truck,
train, or vessel).

Alcoa periodically enters into long-term supply contracts with alumina and aluminum customers and receives advance
payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue, and
revenue is recognized as shipments are made and title, ownership, and risk of loss pass to the customer during the term
of the contracts. Deferred revenue is included in Other current liabilities and Other noncurrent liabilities and deferred
credits on the accompanying Consolidated Balance Sheet.

Environmental Matters. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures
relating to existing conditions caused by past operations, which will not contribute to future revenues, are expensed.
Liabilities are recorded when remediation costs are probable and can be reasonably estimated. The liability may
include costs such as site investigations, consultant fees, feasibility studies, outside contractors, and monitoring
expenses. Estimates are generally not discounted or reduced by potential claims for recovery. Claims for recovery are
recognized as agreements are reached with third parties. The estimates also include costs related to other potentially
responsible parties to the extent that Alcoa has reason to believe such parties will not fully pay their proportionate
share. The liability is continuously reviewed and adjusted to reflect current remediation progress, prospective estimates
of required activity, and other factors that may be relevant, including changes in technology or regulations.

Litigation Matters. For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a
matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an
unfavorable outcome based on many factors such as the nature of the matter, available defenses and case strategy,
progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals
processes, and the outcome of similar historical matters, among others. Once an unfavorable outcome is deemed
probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If
an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is
recorded. With respect to unasserted claims or assessments, management must first determine that the probability that
an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability
to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there
has been a change in management’s judgment regarding the likelihood of an unfavorable outcome or the estimate of a
potential loss.

Asset Retirement Obligations. Alcoa recognizes asset retirement obligations (AROs) related to legal obligations
associated with the normal operation of Alcoa’s bauxite mining, alumina refining, and aluminum smelting facilities.
These AROs consist primarily of costs associated with spent pot lining disposal, closure of bauxite residue areas, mine
reclamation, and landfill closure. Alcoa also recognizes AROs for any significant lease restoration obligation, if
required by a lease agreement, and for the disposal of regulated waste materials related to the demolition of certain
power facilities. The fair values of these AROs are recorded on a discounted basis, at the time the obligation is
incurred, and accreted over time for the change in present value. Additionally, Alcoa capitalizes asset retirement costs
by increasing the carrying amount of the related long-lived assets and depreciating these assets over their remaining
useful life.

Certain conditional asset retirement obligations (CAROs) related to alumina refineries, aluminum smelters, and
fabrication facilities have not been recorded in the Consolidated Financial Statements due to uncertainties surrounding
the ultimate settlement date. A CARO is a legal obligation to perform an asset retirement activity in which the timing

100

and/or method of settlement are conditional on a future event that may or may not be within Alcoa’s control. Such
uncertainties exist as a result of the perpetual nature of the structures, maintenance and upgrade programs, and other
factors. At the date a reasonable estimate of the ultimate settlement date can be made, Alcoa would record an ARO for
the removal, treatment, transportation, storage, and/or disposal of various regulated assets and hazardous materials such
as asbestos, underground and aboveground storage tanks, polychlorinated biphenyls (PCBs), various process residuals,
solid wastes, electronic equipment waste, and various other materials. Such amounts may be material to the
Consolidated Financial Statements in the period in which they are recorded.

Income Taxes. The provision for income taxes is determined using the asset and liability approach of accounting for
income taxes. Under this approach, the provision for income taxes represents income taxes paid or payable (or received
or receivable) for the current year plus the change in deferred taxes during the year. Deferred taxes represent the future
tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid, and result
from differences between the financial and tax bases of Alcoa’s assets and liabilities and are adjusted for changes in tax
rates and tax laws when enacted.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will
not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable
income, including income available in carryback periods, future reversals of taxable temporary differences, projections
of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence.
Positive evidence includes factors such as a history of profitable operations, projections of future profitability within
the carryforward period, including from tax planning strategies, and Alcoa’s experience with similar operations.
Existing favorable contracts and the ability to sell products into established markets are additional positive evidence.
Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that
are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. Deferred
tax assets for which no valuation allowance is recorded may not be realized upon changes in facts and circumstances,
resulting in a future charge to establish a valuation allowance. Existing valuation allowances are re-examined under the
same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax
asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and
liabilities are also re-measured to reflect changes in underlying tax rates due to law changes and the granting and lapse
of tax holidays.

Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such
benefits meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been
effectively settled, which means that the statute of limitation has expired or the appropriate taxing authority has
completed their examination even though the statute of limitations remains open. Interest and penalties related to
uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period
that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits
are recognized.

Stock-Based Compensation. Alcoa recognizes compensation expense for employee equity grants using the non-
substantive vesting period approach, in which the expense (net of estimated forfeitures) is recognized ratably over the
requisite service period based on the grant date fair value. The fair value of new stock options is estimated on the date
of grant using a lattice-pricing model. Determining the fair value of stock options at the grant date requires judgment,
including estimates for the average risk-free interest rate, dividend yield, volatility, and exercise behavior. These
assumptions may differ significantly between grant dates because of changes in the actual results of these inputs that
occur over time.

Most plan participants can choose whether to receive their award in the form of stock options, stock awards, or a
combination of both. This choice is made before the grant is issued and is irrevocable.

Derivatives and Hedging. Derivatives are held for purposes other than trading and are part of a formally documented
risk management program. For derivatives designated as fair value hedges, Alcoa measures hedge effectiveness by
formally assessing, at inception and at least quarterly, the historical high correlation of changes in the fair value of the

101

hedged item and the derivative hedging instrument. For derivatives designated as cash flow hedges, Alcoa measures
hedge effectiveness by formally assessing, at inception and at least quarterly, the probable high correlation of the
expected future cash flows of the hedged item and the derivative hedging instrument. The ineffective portions of both
types of hedges are recorded in sales or other income or expense in the current period. If the hedging relationship
ceases to be highly effective or it becomes probable that an expected transaction will no longer occur, future gains or
losses on the derivative instrument are recorded in other income or expense.

Alcoa accounts for interest rate swaps related to its existing long-term debt and hedges of firm customer commitments
for aluminum as fair value hedges. As a result, the fair values of the derivatives and changes in the fair values of the
underlying hedged items are reported in other current and noncurrent assets and liabilities in the Consolidated Balance
Sheet. Changes in the fair values of these derivatives and underlying hedged items generally offset and are recorded
each period in sales or interest expense, consistent with the underlying hedged item.

Alcoa accounts for hedges of foreign currency exposures and certain forecasted transactions as cash flow hedges. The
fair values of the derivatives are recorded in other current and noncurrent assets and liabilities in the Consolidated
Balance Sheet. The effective portions of the changes in the fair values of these derivatives are recorded in other
comprehensive income and are reclassified to sales, cost of goods sold, or other income or expense in the period in
which earnings are impacted by the hedged items or in the period that the transaction no longer qualifies as a cash flow
hedge. These contracts cover the same periods as known or expected exposures, generally not exceeding five years.

If no hedging relationship is designated, the derivative is marked to market through earnings.

Cash flows from derivatives are recognized in the Statement of Consolidated Cash Flows in a manner consistent with
the underlying transactions.

Foreign Currency. The local currency is the functional currency for Alcoa’s significant operations outside the United
States, except for certain operations in Canada, Russia, and Iceland, where the U.S. dollar is used as the functional
currency. The determination of the functional currency for Alcoa’s operations is made based on the appropriate
economic and management indicators.

Acquisitions. Alcoa’s business acquisitions are accounted for using the acquisition method. The purchase price is
allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess purchase price
over the fair value of the net assets acquired is recorded as goodwill. For all acquisitions, operating results are included
in the Statement of Consolidated Operations from the date of the acquisition.

Discontinued Operations and Assets Held For Sale. For those businesses where management has committed to a
plan to divest, each business is valued at the lower of its carrying amount or estimated fair value less cost to sell. If the
carrying amount of the business exceeds its estimated fair value, an impairment loss is recognized. Fair value is
estimated using accepted valuation techniques such as a DCF model, valuations performed by third parties, earnings
multiples, or indicative bids, when available. A number of significant estimates and assumptions are involved in the
application of these techniques, including the forecasting of markets and market share, sales volumes and prices, costs
and expenses, and multiple other factors. Management considers historical experience and all available information at
the time the estimates are made; however, the fair value that is ultimately realized upon the divestiture of a business
may differ from the estimated fair value reflected in the Consolidated Financial Statements. Depreciation, depletion,
and amortization expense is not recorded on assets of a business to be divested once they are classified as held for sale.
Businesses to be divested are classified in the Consolidated Financial Statements as either discontinued operations or
held for sale.

For businesses classified as discontinued operations, the balance sheet amounts and results of operations are
reclassified from their historical presentation to assets and liabilities of operations held for sale on the Consolidated
Balance Sheet and to discontinued operations on the Statement of Consolidated Operations, respectively, for all periods
presented. The gains or losses associated with these divested businesses are recorded in discontinued operations on the

102

Statement of Consolidated Operations. The Statement of Consolidated Cash Flows is also reclassified for assets and
liabilities of operations held for sale and discontinued operations for all periods presented. Additionally, segment
information does not include the assets or operating results of businesses classified as discontinued operations for all
periods presented. These businesses are expected to be disposed of within one year.

For businesses classified as held for sale that do not qualify for discontinued operations treatment, the balance sheet
and cash flow amounts are reclassified from their historical presentation to assets and liabilities of operations held for
sale for all periods presented. The results of operations continue to be reported in continuing operations. The gains or
losses associated with these divested businesses are recorded in restructuring and other charges on the Statement of
Consolidated Operations. The segment information includes the assets and operating results of businesses classified as
held for sale for all periods presented. Management expects that Alcoa will have continuing involvement with these
businesses following their divestiture, primarily in the form of equity participation, or ongoing aluminum or other
significant supply contracts.

Recently Adopted Accounting Guidance. On January 1, 2015, Alcoa adopted changes issued by the Financial
Accounting Standards Board (FASB) to reporting discontinued operations and disclosures of disposals of components
of an entity. These changes require a disposal of a component to meet a higher threshold in order to be reported as a
discontinued operation in an entity’s financial statements. The threshold is defined as a strategic shift that has, or will
have, a major effect on an entity’s operations and financial results such as a disposal of a major geographical area or a
major line of business. Additionally, the following two criteria have been removed from consideration of whether a
component meets the requirements for discontinued operations presentation: (i) the operations and cash flows of a
disposal component have been or will be eliminated from the ongoing operations of an entity as a result of the disposal
transaction, and (ii) an entity will not have any significant continuing involvement in the operations of the disposal
component after the disposal transaction. Furthermore, equity method investments now may qualify for discontinued
operations presentation. These changes also require expanded disclosures for all disposals of components of an entity,
whether or not the threshold for reporting as a discontinued operation is met, related to profit or loss information and/or
asset and liability information of the component. The adoption of these changes had no impact on the Consolidated
Financial Statements. This guidance will need to be considered in the event Alcoa initiates a disposal of a component.

In September 2015, the FASB issued changes to the accounting for measurement-period adjustments related to business
combinations. Currently, an acquiring entity is required to retrospectively adjust the balance sheet amounts of the acquiree
recognized at the acquisition date with a corresponding adjustment to goodwill during the measurement period, as well as
revise comparative information for prior periods presented within financial statements as needed, including revising
income effects, such as depreciation and amortization, as a result of changes made to the balance sheet amounts of the
acquiree. Such adjustments are required when new information is obtained about facts and circumstances that existed as of
the acquisition date that, if known, would have affected the measurement of the amounts initially recognized or would
have resulted in the recognition of additional assets or liabilities. The measurement period is the period after the
acquisition date during which the acquirer may adjust the balance sheet amounts recognized for a business combination
(generally up to one year from the date of acquisition). The changes eliminate the requirement to make such retrospective
adjustments, and, instead require the acquiring entity to record these adjustments in the reporting period they are
determined. Additionally, the changes require the acquiring entity to present separately on the face of the income
statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period income
by line item that would have been recorded in previous reporting periods if the adjustment to the balance sheet amounts
had been recognized as of the acquisition date. These changes were to become effective for Alcoa on January 1, 2016;
however, early adoption is permitted. As such, Alcoa elected to early adopt these changes upon issuance and applied the
new requirements to three acquisitions (see Note F). In 2015, Alcoa recognized adjustments to the original balance sheet
amounts of these three acquisitions, resulting in the recognition of amounts in current period operations that would have
been recorded in previous reporting periods had the adjustments to the balance sheet amounts been recognized as of the
respective acquisition date. Such amounts recorded in current period operations were not material to the Statement of
Consolidated Operations for the year ended December 31, 2015.

In November 2015, the FASB issued changes to the balance sheet classification of deferred taxes, which Alcoa
immediately adopted. These changes simplify the presentation of deferred income taxes by requiring all deferred

103

income tax assets and liabilities to be classified as noncurrent in a classified balance sheet. The current requirement
that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount
is not affected by these changes. As such, all deferred income tax assets and liabilities were classified in the Deferred
income taxes and Other noncurrent liabilities and deferred credits, respectively, line items on the December 31, 2015
Consolidated Balance Sheet. Additionally, management elected to update the December 31, 2014 Consolidated
Balance Sheet for these changes for comparative purposes. As a result $421 of current deferred income tax assets
(previously reported in Prepaid expenses and other current assets) and $83 of current deferred income tax liabilities
(previously reported in Taxes, including income taxes) were reclassified to the aforementioned noncurrent asset ($385)
and liability ($47) line items on the December 31, 2014 Consolidated Balance Sheet.

Recently Issued Accounting Guidance. In January 2015, the FASB issued changes to the presentation of
extraordinary items. Such items are defined as transactions or events that are both unusual in nature and infrequent in
occurrence, and, currently, are required to be presented separately in an entity’s income statement, net of income tax,
after income from continuing operations. The changes eliminate the concept of an extraordinary item and, therefore,
the presentation of such items will no longer be required. Notwithstanding this change, an entity will still be required to
present and disclose a transaction or event that is both unusual in nature and infrequent in occurrence in the notes to the
financial statements. These changes become effective for Alcoa on January 1, 2016. Management has determined that
the adoption of these changes will not have an impact on the Consolidated Financial Statements.

In February 2015, the FASB issued changes to the analysis that an entity must perform to determine whether it should
consolidate certain types of legal entities. These changes (i) modify the evaluation of whether limited partnerships and
similar legal entities are variable interest entities or voting interest entities, (ii) eliminate the presumption that a general
partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are
involved with variable interest entities, particularly those that have fee arrangements and related party relationships,
and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that
are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the
Investment Company Act of 1940 for registered money market funds. These changes become effective for Alcoa on
January 1, 2016. Management is currently evaluating the potential impact of these changes on the Consolidated
Financial Statements.

In April 2015, the FASB issued changes to the presentation of debt issuance costs. Currently, such costs are required to
be presented as a deferred asset in an entity’s balance sheet and amortized into interest expense over the term of the
related debt instrument. The changes require that debt issuance costs be presented in an entity’s balance sheet as a
direct deduction from the carrying value of the related debt liability. The amortization of debt issuance costs remains
unchanged. These changes become effective for Alcoa on January 1, 2016. In August 2015, the FASB issued an update
to these changes based on an announcement of the staff of the U.S. Securities and Exchange Commission. This change
provides an exception to the April 2015 FASB changes allowing debt issuance costs related to line-of-credit
arrangements to continue to be presented as an asset regardless of whether there are any outstanding borrowings under
such arrangement. This additional change also becomes effective for Alcoa on January 1, 2016. Management has
determined that the adoption of all of these changes will result in a decrease of $58 to both Other noncurrent assets and
Long-term debt, less amount due within one year on the accompanying Consolidated Balance Sheet.

In July 2015, the FASB issued changes to the subsequent measurement of inventory. Currently, an entity is required to
measure its inventory at the lower of cost or market, whereby market can be replacement cost, net realizable value, or
net realizable value less an approximately normal profit margin. The changes require that inventory be measured at the
lower of cost and net realizable value, thereby eliminating the use of the other two market methodologies. Net
realizable value is defined as the estimated selling prices in the ordinary course of business less reasonably predictable
costs of completion, disposal, and transportation. These changes do not apply to inventories measured using LIFO
(last-in, first-out) or the retail inventory method. Currently, Alcoa applies the net realizable value market option to
measure non-LIFO inventories at the lower of cost or market. These changes become effective for Alcoa on January 1,
2017. Management has determined that the adoption of these changes will not have an impact on the Consolidated
Financial Statements.

104

In May 2014, the FASB issued changes to the recognition of revenue from contracts with customers. These changes
created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize
revenue, and, therefore, supersede virtually all existing revenue recognition requirements and guidance. This
framework is expected to result in less complex guidance in application while providing a consistent and comparable
methodology for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to
depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the
entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity should apply
the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the
contract(s), (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the
contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation. In August 2015, the
FASB deferred the effective date by one year, making these changes effective for Alcoa on January 1, 2018.
Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements.

In August 2014, the FASB issued changes to the disclosure of uncertainties about an entity’s ability to continue as a
going concern. Under GAAP, continuation of a reporting entity as a going concern is presumed as the basis for
preparing financial statements unless and until the entity’s liquidation becomes imminent. Even if an entity’s
liquidation is not imminent, there may be conditions or events that raise substantial doubt about the entity’s ability to
continue as a going concern. Because there is no guidance in GAAP about management’s responsibility to evaluate
whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related note
disclosures, there is diversity in practice whether, when, and how an entity discloses the relevant conditions and events
in its financial statements. As a result, these changes require an entity’s management to evaluate whether there are
conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a
going concern within one year after the date that financial statements are issued. Substantial doubt is defined as an
indication that it is probable that an entity will be unable to meet its obligations as they become due within one year
after the date that financial statements are issued. If management has concluded that substantial doubt exists, then the
following disclosures should be made in the financial statements: (i) principal conditions or events that raised the
substantial doubt, (ii) management’s evaluation of the significance of those conditions or events in relation to the
entity’s ability to meet its obligations, (iii) management’s plans that alleviated the initial substantial doubt or, if
substantial doubt was not alleviated, management’s plans that are intended to at least mitigate the conditions or events
that raise substantial doubt, and (iv) if the latter in (iii) is disclosed, an explicit statement that there is substantial doubt
about the entity’s ability to continue as a going concern. These changes become effective for Alcoa for the 2016 annual
period. Management has determined that the adoption of these changes will not have an impact on the Consolidated
Financial Statements. Subsequent to adoption, this guidance will need to be applied by management at the end of each
annual period and interim period therein to determine what, if any, impact there will be on the Consolidated Financial
Statements in a given reporting period.

C. Asset Retirement Obligations

Alcoa has recorded AROs related to legal obligations associated with the normal operations of bauxite mining, alumina
refining, and aluminum smelting facilities. These AROs consist primarily of costs associated with spent pot lining
disposal, closure of bauxite residue areas, mine reclamation, and landfill closure. Alcoa also recognizes AROs for any
significant lease restoration obligation, if required by a lease agreement, and for the disposal of regulated waste
materials related to the demolition of certain power facilities.

In addition to AROs, certain CAROs related to alumina refineries, aluminum smelters, and fabrication facilities have
not been recorded in the Consolidated Financial Statements due to uncertainties surrounding the ultimate settlement
date. Such uncertainties exist as a result of the perpetual nature of the structures, maintenance and upgrade programs,
and other factors. At the date a reasonable estimate of the ultimate settlement date can be made (e.g., planned
demolition), Alcoa would record an ARO for the removal, treatment, transportation, storage, and/or disposal of various
regulated assets and hazardous materials such as asbestos, underground and aboveground storage tanks, PCBs, various
process residuals, solid wastes, electronic equipment waste, and various other materials. If Alcoa was required to
demolish all such structures immediately, the estimated CARO as of December 31, 2015 ranges from less than $1 to
$46 per structure (156 structures) in today’s dollars.

The following table details the carrying value of recorded AROs by major category (of which $97 and $76 was
classified as a current liability as of December 31, 2015 and 2014, respectively):

Layoff costs were recorded based on approved detailed action plans submitted by the operating locations that specified
positions to be eliminated, benefits to be paid under existing severance plans, union contracts or statutory requirements,
and the expected timetable for completion of the plans.

2015 Actions. In 2015, Alcoa recorded Restructuring and other charges of $1,195 ($836 after-tax and noncontrolling
interest), which were comprised of the following components: $438 ($281 after-tax and noncontrolling interest) for exit
costs related to decisions to permanently shut down and demolish three smelters and a power station (see below); $246
($118 after-tax and noncontrolling interest) for the curtailment of two refineries and two smelters (see below); $201
(pre- and after-tax) related to legal matters in Italy (see Note N); a $161 ($151 after-tax and noncontrolling interest) net
loss related to the March 2015 divestiture of a rolling mill in Russia and post-closing adjustments associated with three
December 2014 divestitures (see Note F); $143 ($102 after-tax and noncontrolling interest) for layoff costs, including
the separation of approximately 2,100 employees (425 in the Transportation and Construction Solutions segment, 645
in the Engineered Products and Solutions segment, 380 in the Primary Metals segment, 90 in the Global Rolled
Products segment, 85 in the Alumina segment, and 475 in Corporate); $34 ($14 after-tax and noncontrolling interest)
for asset impairments, virtually all of which was related to prior capitalized costs for an expansion project at a refinery
in Australia that is no longer being pursued; an $18 ($13 after-tax) gain on the sale of land related to one of the rolling
mills in Australia that was permanently closed in December 2014 (see 2014 Actions below); a net charge of $4 (a net
credit of $7 after-tax and noncontrolling interest) for other miscellaneous items; and $14 ($11 after-tax and
noncontrolling interest) for the reversal of a number of small layoff reserves related to prior periods.

During 2015, management initiated various alumina refining and aluminum smelting capacity curtailments and/or
closures. The curtailments were composed of the remaining capacity at all of the following: the São Luís smelter in
Brazil (74,000 metric-tons-per-year); the Suriname refinery (1,330,000 metric-tons-per-year); the Point Comfort, TX

108

refinery (2,010,000 metric-tons-per-year); and the Wenatchee, WA smelter (143,000 metric-tons-per-year). All of the
curtailments were completed in 2015 except for 1,635,000 metric-tons-per-year at the Point Comfort refinery, which is
expected to be completed by the end of June 2016. The permanent closures were composed of the capacity at the
Warrick, IN smelter (269,000 metric-tons-per-year) (includes the closure of a related coal mine) and the infrastructure
of the Massena East, NY smelter (potlines were previously shut down in both 2013 and 2014—see 2013 Actions and
2014 Actions below), as the modernization of this smelter is no longer being pursued. The shutdown of the Warrick
smelter is expected to be completed by the end of March 2016.

The decisions on the above actions were part of a separate 12-month review in refining (2,800,000 metric-tons-per-
year) and smelting (500,000 metric-tons-per-year) capacity initiated by management in March 2015 for possible
curtailment (partial or full), permanent closure or divestiture. While many factors contributed to each decision, in
general, these actions were initiated to maintain competitiveness amid prevailing market conditions for both alumina
and aluminum. Demolition and remediation activities related to the Warrick smelter and the Massena East location will
begin in 2016 and are expected to be completed by the end of 2020.

Separate from the actions initiated under the reviews described above, in mid-2015, management approved the
permanent shutdown and demolition of the Poços de Caldas smelter (capacity of 96,000 metric-tons-per-year) in Brazil
and the Anglesea power station (includes the closure of a related coal mine) in Australia. The entire capacity at Poços
de Caldas had been temporarily idled since May 2014 and the Anglesea power station was shut down at the end of
August 2015. Demolition and remediation activities related to the Poços de Caldas smelter and the Anglesea power
station began in late 2015 and are expected to be completed by the end of 2026 and 2020, respectively.

The decision on the Poços de Caldas smelter was due to management’s conclusion that the smelter was no longer
competitive as a result of challenging global market conditions for primary aluminum, which led to the initial
curtailment, that have not dissipated and higher costs. For the Anglesea power station, the decision was made because a
sale process did not result in a sale and there would have been imminent operating costs and financial constraints
related to this site in the remainder of 2015 and beyond, including significant costs to source coal from available
resources, necessary maintenance costs, and a depressed outlook for forward electricity prices. The Anglesea power
station previously supplied approximately 40 percent of the power needs for the Point Henry smelter, which was closed
in August 2014 (see 2014 Actions below).

In 2015, costs related to the shutdown and curtailment actions included asset impairments of $217, representing the
write-off of the remaining book value of all related properties, plants, and equipment; $156 for the layoff of
approximately 3,100 employees (1,800 in the Primary Metals segment and 1,300 in the Alumina segment), including
$30 in pension costs (see Note W); accelerated depreciation of $84 related to certain facilities as they continued to
operate during 2015; and $227 in other exit costs. Additionally in 2015, remaining inventories, mostly operating
supplies and raw materials, were written down to their net realizable value, resulting in a charge of $90 ($43 after-tax
and noncontrolling interest), which was recorded in Cost of goods sold on the accompanying Statement of
Consolidated Operations. The other exit costs of $227 represent $76 in asset retirement obligations and $86 in
environmental remediation, both of which were triggered by the decisions to permanently shut down and demolish the
aforementioned structures in the United States, Brazil, and Australia (includes the rehabilitation of a related coal mine
in each of Australia and the United States), and $65 in supplier and customer contract-related costs.

As of December 31, 2015, approximately 1,500 of the 5,200 employees were separated. The remaining separations for
2015 restructuring programs are expected to be completed by the end of 2016. In 2015, cash payments of $42 were
made against layoff reserves related to 2015 restructuring programs.

2014 Actions. In 2014, Alcoa recorded Restructuring and other charges of $1,168 ($703 after-tax and noncontrolling
interest), which were comprised of the following components: $693 ($443 after-tax and noncontrolling interest) for exit
costs related to decisions to permanently shut down and demolish three smelters and two rolling mills (see below); a
$332 ($163 after-tax and noncontrolling interest) net loss for the divestitures of four operations (see Note F); $68 ($45
after-tax and noncontrolling interest) for the temporary curtailment of two smelters and a related production slowdown

109

at one refinery (see below); $51 ($36 after-tax and noncontrolling interest) for layoff costs, including the separation of
approximately 1,120 employees (470 in the Engineered Products and Solutions segment, 360 in the Transportation and
Construction Solutions segment, 45 in the Global Rolled Products segment, 60 in the Alumina and Primary Metals
segments combined, and 185 in Corporate); $34 ($26 after-tax) for asset impairments related to prior capitalized costs
for a modernization project at a smelter in Canada that is no longer being pursued; a net charge of $18 ($11 after-tax
and noncontrolling interest) for other miscellaneous items, including $2 ($2 after-tax) for asset impairments and
accelerated depreciation; and $28 ($21 after-tax and noncontrolling interest) for the reversal of a number of layoff
reserves related to prior periods, including those associated with a smelter in Italy due to changes in facts and
circumstances (see below).

In early 2014, management approved the permanent shutdown and demolition of the remaining capacity (84,000
metric-tons-per-year) at the Massena East, NY smelter and the full capacity (190,000 metric-tons-per-year) at the Point
Henry smelter in Australia. The capacity at Massena East was fully shut down by the end of March 2014 and the Point
Henry smelter was fully shut down in August 2014. Demolition and remediation activities related to both the Massena
East and Point Henry smelters began in late 2014 and are expected to be completed by the end of 2020 and 2018,
respectively.

The decisions on the Massena East and Point Henry smelters were part of a 15-month review of 460,000 metric tons of
smelting capacity initiated by management in May 2013 (see 2013 Actions below) for possible curtailment. Through
this review, management determined that the remaining capacity of the Massena East smelter was no longer
competitive and the Point Henry smelter had no prospect of becoming financially viable. Management also initiated the
temporary curtailment of the remaining capacity (62,000 metric-tons-per-year) at the Poços de Caldas smelter and
additional capacity (85,000 metric-tons-per-year) at the São Luís smelter, both in Brazil. These curtailments were
completed by the end of May 2014. As a result of these curtailments, 200,000 metric-tons-per-year of production at the
Poços de Caldas refinery was reduced by the end of June 2014.

Also in early 2014, management approved the permanent shutdown of Alcoa’s two rolling mills in Australia, Point
Henry and Yennora. This decision was made due to the significant impact of excess can sheet capacity in both
Australia and Asia. The two rolling mills had a combined can sheet capacity of 200,000 metric-tons-per-year and were
closed by the end of 2014. Demolition and remediation activities related to the two rolling mills began in mid-2015 and
are expected to be completed by the end of 2018.

Additionally, in August 2014, management approved the permanent shutdown and demolition of the capacity (150,000
metric-tons-per-year) at the Portovesme smelter in Italy, which had been idle since November 2012. This decision was
made because the fundamental reasons that made the Portovesme smelter uncompetitive remained unchanged,
including the lack of a viable long-term power solution. Demolition and remediation activities related to the
Portovesme smelter will begin in 2016 and are expected to be completed by the end of 2020 (delayed due to
discussions with the Italian government and other stakeholders).

In 2014, costs related to the shutdown and curtailment actions included $208 for the layoff of approximately 1,790
employees (1,210 in the Primary Metals segment, 470 in the Global Rolled Products segment, 80 in the Alumina
segment, and 30 in Corporate), including $26 in pension costs (see Note W); accelerated depreciation of $204 related
to the three facilities in Australia as they continued to operate during 2014; asset impairments of $166 representing the
write-off of the remaining book value of all related properties, plants, and equipment; and $183 in other exit costs.
Additionally in 2014, remaining inventories, mostly operating supplies and raw materials, were written down to their
net realizable value, resulting in a charge of $67 ($47 after-tax and noncontrolling interest), which was recorded in
Cost of goods sold on the accompanying Statement of Consolidated Operations. The other exit costs of $183 represent
$95 in asset retirement obligations and $42 in environmental remediation, both of which were triggered by the
decisions to permanently shut down and demolish the aforementioned structures in Australia, Italy, and the United
States, and $46 in other related costs, including supplier and customer contract-related costs.

110

As of December 31, 2015, approximately 2,500 of the 2,870 employees (previously 2,910) were separated. The total
number of employees associated with 2014 restructuring programs was updated to reflect employees, who were
initially identified for separation, accepting other positions within Alcoa and natural attrition. The remaining
separations for 2014 restructuring programs are expected to be completed by the end of 2016. In 2015 and 2014, cash
payments of $62 and $141, respectively, were made against layoff reserves related to 2014 restructuring programs.

2013 Actions. In 2013, Alcoa recorded Restructuring and other charges of $782 ($585 after-tax and noncontrolling
interests), which were comprised of the following components: $391 ($305 after-tax and noncontrolling interest)
related to the resolution of a legal matter (see Government Investigations under Litigation in Note N); $245 ($183
after-tax) for exit costs related to the permanent shutdown and demolition of certain structures at three smelter
locations (see below); $87 ($61 after-tax and noncontrolling interests) for layoff costs, including the separation of
approximately 1,110 employees (340 in the Primary Metals segment, 250 in the Global Rolled Products segment, 220
in the Engineered Products and Solutions segment, 85 in the Alumina segment, 75 in the Transportation and
Construction Solutions segment and 140 in Corporate), of which 590 relates to a global overhead reduction program,
and $9 in pension plan settlement charges related to previously separated employees; $25 ($17 after-tax) in net charges,
including $12 ($8 after-tax) for asset impairments, related to retirements and/or the sale of previously idled structures;
$25 ($13 after-tax and noncontrolling interests) for asset impairments related to the write-off of capitalized costs for
projects no longer being pursued due to the market environment; a net charge of $17 ($12 after-tax and noncontrolling
interests) for other miscellaneous items, including $3 ($2 after-tax) for asset impairments; and $8 ($6 after-tax and
noncontrolling interests) for the reversal of a number of small layoff reserves related to prior periods.

In May 2013, management approved the permanent shutdown and demolition of two potlines (capacity of 105,000
metric-tons-per-year) that utilize Soderberg technology at the Baie Comeau smelter in Québec, Canada (remaining
capacity of 280,000 metric-tons-per-year composed of two prebake potlines) and the full capacity (44,000 metric-tons-
per-year) at the Fusina smelter in Italy. Additionally, in August 2013, management approved the permanent shutdown
and demolition of one potline (capacity of 41,000 metric-tons-per-year) that utilizes Soderberg technology at the
Massena East, NY smelter (remaining capacity of 84,000 metric-tons-per-year composed of two Soderberg potlines).
The aforementioned Soderberg lines at Baie Comeau and Massena East were fully shut down by the end of September
2013 while the Fusina smelter was previously temporarily idled in 2010. Demolition and remediation activities related
to all three facilities began in late 2013 and are expected to be completed by the end of 2016 for Massena East and by
the end of 2017 for both Baie Comeau and Fusina.

The decisions on the Soderberg lines for Baie Comeau and Massena East were part of a 15-month review of 460,000
metric tons of smelting capacity initiated by management in May 2013 for possible curtailment, while the decision on
the Fusina smelter was in addition to the capacity being reviewed. Factors leading to all three decisions were in general
focused on achieving sustained competitiveness and included, among others: lack of an economically viable, long-term
power solution (Italy); changed market fundamentals; other existing idle capacity; and restart costs.

In 2013, exit costs related to the shutdown actions included $114 for the layoff of approximately 550 employees
(Primary Metals segment), including $83 in pension costs (see Note W); accelerated depreciation of $58 (Baie
Comeau) and asset impairments of $18 (Fusina and Massena East) representing the write-off of the remaining book
value of all related properties, plants, and equipment; and $55 in other exit costs. Additionally in 2013, remaining
inventories, mostly operating supplies and raw materials, were written down to their net realizable value resulting in a
charge of $9 ($6 after-tax), which was recorded in Cost of goods sold on the accompanying Statement of Consolidated
Operations. The other exit costs of $55 represent $48 in asset retirement obligations and $5 in environmental
remediation, both of which were triggered by the decisions to permanently shut down and demolish these structures,
and $2 in other related costs.

As of December 31, 2015, the separations associated with 2013 restructuring programs were essentially complete. In
2015, 2014, and 2013, cash payments of $7, $39, and $33, respectively, were made against layoff reserves related to
2013 restructuring programs.

In 2015, 2014, and 2013, Other for layoff costs also included a reclassification of $35, $26, and $92, respectively, in
pension and/or other postretirement benefits costs, as these obligations were included in Alcoa’s separate liability for
pension and other postretirement benefits obligations (see Note W). Additionally in 2015, 2014, and 2013, Other for
other exit costs also included a reclassification of the following restructuring charges: $76, $95, and $58,
respectively, in asset retirement and $86, $47, and $12, respectively, in environmental obligations, as these liabilities
were included in Alcoa’s separate reserves for asset retirement obligations (see Note C) and environmental
remediation (see Note N).

The remaining reserves are expected to be paid in cash during 2016, with the exception of approximately $10 to $15,
which is expected to be paid over the next several years for ongoing site remediation work and special layoff benefit
payments.

* As of December 31, 2015, the amount reflected in Corporate is allocated to four of Alcoa’s five reportable segments

($146 to Alumina, $59 to Global Rolled Products, $253 to Engineered Products and Solutions, and $18 to
Transportation and Construction Solutions) included in the table above for purposes of impairment testing (see Note
A). This goodwill is reflected in Corporate for segment reporting purposes because it is not included in
management’s assessment of performance by the four reportable segments.

In 2015 and 2013, Alcoa recognized an impairment of goodwill in the amount of $25 and $1,731 ($1,719 after
noncontrolling interest), respectively, related to the annual impairment review of the soft alloy extrusion business in
Brazil (included in the Transportation and Construction Solutions segment) and the Primary Metals segment,
respectively, (see Goodwill and Other Intangible Assets policy in Note A).

Alcoa to drive common systems among all businesses.

Amortization expense related to the intangible assets in the tables above for the years ended December 31, 2015, 2014,
and 2013 was $77, $69, and $73, respectively, and is expected to be in the range of approximately $75 to $85 annually
from 2016 to 2020.

F. Acquisitions and Divestitures

Pro forma results of the Company, assuming all acquisitions described below were made at the beginning of the earliest
prior period presented, would not have been materially different from the results reported.

2015 Acquisitions. In March 2015, Alcoa completed the acquisition of an aerospace structural castings company,
TITAL, for $204 (€188) in cash (an additional $1 (€1) was paid in September 2015 to settle working capital in
accordance with the purchase agreement). This transaction is no longer subject to post-closing adjustments. TITAL, a
privately held company with approximately 650 employees based in Germany, produces aluminum and titanium
investment casting products for the aerospace and defense end markets. The purpose of this acquisition is to capture
increasing demand for advanced jet engine components made of titanium, establish titanium-casting capabilities in
Europe, and expand existing aluminum casting capacity. The assets, including the associated goodwill, and liabilities of
this business were included within Alcoa’s Engineered Products and Solutions segment since the date of acquisition.
Based on the preliminary allocation of the purchase price, goodwill of $118 was recorded for this transaction, none of
which is estimated to be deductible for income tax purposes. The final allocation of the purchase price will be based on
management’s best estimates, including a third-party valuation of certain assets acquired, which may result in the
identification of other intangible assets. This valuation is expected to be completed in March 2016.

114

Also in March 2015, Alcoa signed a definitive agreement to acquire RTI International Metals, Inc. (RTI), a U.S.
company that was publicly traded on the New York Stock Exchange under the ticker symbol “RTI.” On July 23, 2015,
after satisfying all customary closing conditions and receiving the required regulatory and RTI shareholder approvals,
Alcoa completed the acquisition of RTI. Alcoa purchased all outstanding shares of RTI common stock in a stock-for-
stock transaction valued at $870 (based on the $9.96 per share July 23, 2015 closing price of Alcoa’s common stock).
Each issued and outstanding share of RTI common stock prior to the completion of the transaction was converted into
the right to receive 2.8315 shares of Alcoa common stock. In total, Alcoa issued 87,397,414 shares of its common
stock to consummate this transaction, which was not reflected in the accompanying Statement of Consolidated Cash
Flows as it represents a noncash financing activity. The exchange ratio was the quotient of a $41 per RTI common
share acquisition price and the $14.48 per share March 6, 2015 closing price of Alcoa’s common stock. In addition to
the transaction price, Alcoa also paid $25 ($19 after-tax) in professional fees and costs related to this acquisition. This
amount was recorded in Selling, general administrative, and other expenses on the accompanying Statement of
Consolidated Operations.

RTI is a global supplier of titanium and specialty metal products and services for the commercial aerospace, defense,
energy, and medical device end markets. The purpose of this acquisition is to expand Alcoa’s range of titanium
offerings and add advanced technologies and materials, primarily related to the aerospace end market. In 2014, RTI
generated net sales of $794 and had approximately 2,600 employees. The operating results and assets and liabilities of
RTI were included within Alcoa’s Engineered Products and Solutions segment since the date of acquisition. Third-
party sales and after-tax operating income (Alcoa’s primary segment performance measure—see Note Q) of RTI from
the acquisition date through December 31, 2015 were $309 and less than $(1), respectively.

The following table represents the preliminary allocation of the purchase price by major asset acquired and liability
assumed, as well as the amount of goodwill recognized:

The amounts in the table above are subject to change based, in part, on management’s review of a third-party valuation
of the assets acquired and liabilities assumed, which is expected to be completed in mid-2016.

115

As reflected in the table above, Alcoa recognized goodwill of $240, which represents the earnings growth potential
of RTI, Alcoa’s ability to expand its titanium capabilities in the aerospace market, and expected synergies from
combining the operations of the two companies. This goodwill was allocated to a new Alcoa reporting unit
associated with the Engineered Products and Solutions segment, Alcoa Titanium and Engineered Products, which
consists solely of the acquired RTI business. None of this goodwill is deductible for income tax purposes.

The other noncurrent assets in the table above include an estimate for intangible assets of $73, most of which were
included in Alcoa’s other intangibles class (see Note E). The specific identification and weighted-average amortization
period for these intangible assets is dependent on the final valuation.

As part of this acquisition, Alcoa assumed the obligation to repay two tranches of convertible debt; one tranche was due
and settled in cash on December 1, 2015 (principal amount of $115) and the other tranche is due on October 15, 2019
(principal amount of $403). Upon conversion of the 2019 convertible notes in accordance with their terms, holders will
receive, at Alcoa’s election, cash, shares of common stock (up to 27,990,966 shares), or a combination of cash and
shares. This cash conversion feature requires the convertible notes to be bifurcated into a liability component and an
equity component. The fair value of the liability component was determined by calculating the net present value of the
cash flows of the convertible notes using the interest rate of a similar instrument without a conversion feature. The fair
value of the equity component is the difference between the fair value of the entire instrument on the date of acquisition
and the fair value of the liability and is included as Additional capital on the accompanying Consolidated Balance Sheet.

2015 Divestitures. In 2015, Alcoa completed the divestiture of an operation in Russia (see below) and had post-closing
adjustments, as provided for in the respective purchase agreements, related to three divestitures completed in
December 2014 (see 2014 Divestitures below). The divestiture and post-closing adjustments combined resulted in net
cash received of $30 and a net loss of $161 ($151 after-tax and noncontrolling interest), which was recorded in
Restructuring and other charges (see Note D) on the accompanying Statement of Consolidated Operations. These four
divestitures are no longer subject to post-closing adjustments.

In March 2015, Alcoa completed the sale of a rolling mill located in Belaya Kalitva, Russia to a wholly-owned
subsidiary of Stupino Titanium Company. While owned by Alcoa, the operating results and assets and liabilities of the
rolling mill were included in the Global Rolled Products segment. The rolling mill generated sales of approximately
$130 in 2014 and, at the time of divestiture, had approximately 1,870 employees.

2014 Acquisitions. In June 2014, Alcoa signed a purchase agreement to acquire an aerospace jet engine components
company, Firth Rixson, from Oak Hill Capital Partners for $2,850. The purchase price was composed of $2,350 in cash
and $500 of Alcoa common stock. The common stock component was equivalent to 36,523,010 shares at a per share
price of $13.69, as determined in the agreement. In conjunction with the purchase agreement, Alcoa also entered into
an earn-out agreement, which states that Alcoa will make earn-out payments up to an aggregate maximum amount of
$150 through December 31, 2020 upon certain conditions (see below for additional information). On November 19,
2014, after satisfying all customary closing conditions and receiving the required regulatory approvals, Alcoa
completed the acquisition of Firth Rixson for $2,995. The purchase price was composed of $2,385 in cash (net of cash
acquired) and $610 of Alcoa common stock. The cash portion of the transaction price increased by $35 due to working
capital and other adjustments based on the provisions of the purchase agreement. The common stock portion of the
transaction price was based on the closing market price ($16.69 per share) of Alcoa’s common stock on the acquisition
date. This transaction is subject to certain post-closing adjustments as defined in the purchase agreement.

In addition to the transaction price, Alcoa also paid $42 ($34 after-tax) in professional fees and costs related to this
acquisition. This amount was recorded in Selling, general administrative, and other expenses on the accompanying
Statement of Consolidated Operations. Additionally, Alcoa recorded $13 ($8 after-tax) in Interest expense on the
accompanying Statement of Consolidated Operations for costs associated with the execution (in June 2014) and
termination (in September 2014) of a $2,500 364-day senior unsecured bridge term loan facility. This facility was
entered into for the purpose of financing all or a portion of the cash consideration for this acquisition and to pay fees and
expenses incurred in connection therewith. However, in September 2014, the facility was no longer necessary as Alcoa
completed the issuance of $2,500 in debt (see Note K) and equity (see Note R) instruments to finance the acquisition.

116

Firth Rixson manufactures rings, forgings, and metal products for the aerospace end market, as well as other markets
requiring highly engineered material applications. This business has 13 operating facilities in the United States, United
Kingdom, Europe, and Asia employing approximately 2,400 people combined. The purpose of this acquisition is to
strengthen Alcoa’s aerospace business and position the Company to capture additional aerospace growth with a broader
range of high-growth, value-add jet engine components. The operating results and assets and liabilities of Firth Rixson
were included within the Engineered Products and Solutions segment since the date of acquisition. Third-party sales
and after-tax operating income (Alcoa’s primary segment performance measure—see Note Q) of Firth Rixson from the
acquisition date through December 31, 2014 were $81 and $(12), respectively.

The following table represents the final allocation of the purchase price by major asset acquired and liability assumed,
as well as the amount of goodwill recognized and the net present value of the potential earn-out:

As reflected in the table above, Alcoa recognized goodwill of $1,801, which represents the earnings growth potential of
Firth Rixson and expected synergies from combining the operations of the two companies. The goodwill was allocated
to two of Alcoa’s reporting units associated with the Engineered Products and Solutions segment, Alcoa Fastening
Systems and Rings ($1,117) and Alcoa Forging and Extrusions ($684), on a relative fair value basis. None of the
goodwill is deductible for income tax purposes.

The other noncurrent assets in the table above represent intangible assets, which were included in the other intangibles
class (see Note E). These intangible assets consist primarily of customer relationships and contracts, backlog,
qualifications, and technology, and have a weighted-average amortization period of 35 years.

The contingent consideration liability presented in the table above represents the net present value of the potential
earn-out of $150 (Level 3 in the fair value hierarchy—see Note X). This earn-out is contingent on the Firth Rixson
forging business in Savannah, Georgia achieving certain identified financial targets through December 31, 2020.
Management has determined that payment of the maximum amount is probable based on the forecasted financial
performance of this location. It is estimated that the earn-out will be paid in 2019 through 2020. The fair value of this
liability will be updated in future periods with any change resulting in a corresponding charge or credit to earnings.

In August 2014, Alcoa completed the acquisition of the 30% outstanding noncontrolling interest in the aluminum
brazing sheet venture in Kunshan City, China from Shanxi Yuncheng Engraving Group for $28. The $3 difference
between the purchase price and the carrying value of the noncontrolling interest on Alcoa’s Consolidated Balance
Sheet was included in Additional capital.

117

2014 Divestitures. In 2014, Alcoa completed the divestiture of four operations as described below. Combined, these
transactions yielded net cash proceeds of $247 and resulted in a net loss of $332 ($163 after-tax and noncontrolling
interest), which was recorded in Restructuring and other charges (see Note D) on the accompanying Statement of
Consolidated Operations. All four transactions were subject to certain post-closing adjustments as defined in the
respective purchase agreements as of December 31, 2014 (see 2015 Divestitures above).

In November 2014, Alcoa completed the sale of an aluminum rod plant located in Bécancour, Québec, Canada to Sural
Laminated Products. This facility takes molten aluminum and shapes it into the form of a rod, which is used by
customers primarily for the transportation of electricity. While owned by Alcoa, the operating results and assets and
liabilities of this plant were included in the Primary Metals segment. In conjunction with this transaction, Alcoa
entered into a multi-year agreement with Sural Laminated Products to supply molten aluminum for the rod plant. The
aluminum rod plant generated sales of approximately $200 in 2013 and, at the time of divestiture, had approximately
60 employees.

In December 2014, Alcoa’s majority-owned subsidiary (60%), Alcoa World Alumina and Chemicals (AWAC),
completed the sale of its ownership stake in a bauxite mine and alumina refinery joint venture in Jamaica to Noble
Group Ltd. The joint venture was 55% owned by a subsidiary of AWAC, which is 40% owned by Alumina Limited.
While owned by AWAC, 55% of both the operating results and assets and liabilities of this joint venture were included
in the Alumina segment. As it relates to AWAC’s previous 55% ownership stake, the refinery (AWAC’s share of the
capacity was 778,800 metric-tons-per-year) generated sales (third-party and intersegment) of approximately $200 in
2013, and the refinery and mine combined, at the time of divestiture, had approximately 500 employees.

Also in December 2014, Alcoa completed the sale of its 50.33% ownership stake in the Mt. Holly smelter located in
Goose Creek, South Carolina to Century Aluminum Company. While owned by Alcoa, 50.33% of both the operating
results and assets and liabilities related to the smelter were included in the Primary Metals segment. As it relates to
Alcoa’s previous 50.33% ownership stake, the smelter (Alcoa’s share of the capacity was 115,000 metric-tons-
per-year) generated sales of approximately $280 in 2013 and, at the time of divestiture, had approximately 250
employees.

Additionally in December 2014, Alcoa completed the sale of three rolling mills located in Spain (Alicante and
Amorebieta) and France (Castelsarrasin) to a subsidiary of Atlas Holdings LLC. While owned by Alcoa, the operating
results and assets and liabilities of the rolling mills were included in the Global Rolled Products segment. In
conjunction with this transaction, Alcoa entered into a multi-year agreement with the buyer to supply aluminum for the
rolling mills. The rolling mills combined generated sales of approximately $500 in 2013 and, at the time of divestiture,
had approximately 750 employees.

At December 31, 2015 and 2014, the total amount of inventories valued on a LIFO basis was $1,373 and $1,514,
respectively. If valued on an average-cost basis, total inventories would have been $559 and $767 higher at
December 31, 2015 and 2014, respectively. During 2015 and 2013, reductions in LIFO inventory quantities caused
partial liquidations of the lower cost LIFO inventory base. These liquidations resulted in the recognition of income of
$1 ($1 after-tax) in 2015 and $26 ($17 after-tax) in 2013.

Equity Investments. As of December 31, 2015 and 2014, Equity investments included an interest in a project to develop a
fully-integrated aluminum complex in Saudi Arabia (see below); bauxite mining interests in Guinea (45% of Halco Mining,
Inc.) and Brazil (18.2% of Mineração Rio do Norte S.A.); two hydroelectric power projects in Brazil (see Note N); a natural
gas pipeline in Australia (see Note N); a smelter operation in Canada (50% of Pechiney Reynolds Quebec, Inc.); and a
hydroelectric power company in Canada (40% of Manicouagan Power Limited Partnership). Pechiney Reynolds Quebec,
Inc. owns a 50.1% interest in the Bécancour smelter in Quebec, Canada thereby entitling Alcoa to a 25.05% interest in the
smelter. Through two wholly-owned Canadian subsidiaries, Alcoa also owns 49.9% of the Bécancour smelter. Halco Mining,
Inc. owns 100% of Boké Investment Company, which owns 51% of Compagnie des Bauxites de Guinée. The investments in
the bauxite mining interests in Guinea and Brazil and the natural gas pipeline in Australia are held by wholly-owned
subsidiaries of Alcoa World Alumina and Chemicals (AWAC), which is owned 60% by Alcoa and 40% by Alumina
Limited. In 2015, 2014, and 2013, Alcoa received $152, $86, and $89, respectively, in dividends from its equity investments.

Alcoa and Saudi Arabian Mining Company (known as “Ma’aden”) have a 30-year (from December 2009) joint venture
shareholders’ agreement (automatic extension for an additional 20 years, unless the parties agree otherwise or unless
earlier terminated) setting forth the terms for the development, construction, ownership, and operation of an integrated
aluminum complex in Saudi Arabia. Specifically, the project being developed by the joint venture consists of: (i) a
bauxite mine for the extraction of approximately 4,000 kmt of bauxite from the Al Ba’itha bauxite deposit near Quiba
in the northern part of Saudi Arabia; (ii) an alumina refinery with an initial capacity of 1,800 kmt; (iii) a primary
aluminum smelter with an initial capacity of 740 kmt; and (iv) a rolling mill with an initial capacity of 380 kmt. The
refinery, smelter, and rolling mill have been constructed in an industrial area at Ras Al Khair on the east coast of Saudi
Arabia. The facilities use critical infrastructure, including power generation derived from reserves of natural gas, as
well as port and rail facilities, developed by the government of Saudi Arabia. First production from the smelter, rolling
mill, and mine and refinery occurred in December of 2012, 2013, and 2014, respectively.

In 2012, Alcoa and Ma’aden agreed to expand the capabilities of the rolling mill to include a capacity of 100 kmt
dedicated to supplying aluminum automotive, building and construction, and foil stock sheet. First production related
to the expanded capacity occurred in 2014. This expansion is not expected to result in additional equity investment (see
below) due to significant savings anticipated from a change in the project execution strategy of the initial 380 kmt
capacity of the rolling mill.

The joint venture is owned 74.9% by Ma’aden and 25.1% by Alcoa and consists of three separate companies as
follows: one each for the mine and refinery, the smelter, and the rolling mill. Following the signing of the joint venture
shareholders’ agreement, Alcoa paid Ma’aden $80 representing the initial investment in the project. In addition, Alcoa
paid $56 to Ma’aden, representing Alcoa’s pro rata share of certain agreed upon pre-incorporation costs incurred by
Ma’aden prior to formation of the joint venture.

Ma’aden and Alcoa have put and call options, respectively, whereby Ma’aden can require Alcoa to purchase from
Ma’aden, or Alcoa can require Ma’aden to sell to Alcoa, a 14.9% interest in the joint venture at the then fair market
value. These options may only be exercised in a six-month window that opens five years after the Commercial
Production Date (as defined in the joint venture shareholders’ agreement) and, if exercised, must be exercised for the
full 14.9% interest. The Commercial Production Date for the smelting company was declared on September 1, 2014.
There have not been similar declarations yet for the rolling mill company and the mining and refining company.

The Alcoa affiliate that holds Alcoa’s interests in the smelting company and the rolling mill company is wholly owned
by Alcoa, and the Alcoa affiliate that holds Alcoa’s interests in the mining and refining company is wholly owned by
AWAC. Except in limited circumstances, Alcoa may not sell, transfer or otherwise dispose of or encumber or enter into
any agreement in respect of the votes or other rights attached to its interests in the joint venture without Ma’aden’s
prior written consent.

A number of Alcoa employees perform various types of services for the smelting, rolling mill, and refining and mining
companies as part of the construction of the fully-integrated aluminum complex. At December 31, 2015 and 2014,
Alcoa had an outstanding receivable of $19 and $30, respectively, from the smelting, rolling mill, and refining and
mining companies for labor and other employee-related expenses.

120

Capital investment in the project is expected to total approximately $10,800 (SAR 40.5 billion) and has been funded
through a combination of equity contributions by the joint venture partners and project financing by the joint venture,
which has been guaranteed by both partners (see below). Both the equity contributions and the guarantees of the project
financing are based on the joint venture’s partners’ ownership interests. Originally, it was estimated that Alcoa’s total
equity investment in the joint venture would be approximately $1,100, of which Alcoa has contributed $981, including
$29 and $120 in 2015 and 2014, respectively. Based on changes to both the project’s capital investment and equity and
debt structure from the initial plans, the estimated $1,100 equity contribution may be reduced. As of December 31,
2015 and 2014, the carrying value of Alcoa’s investment in this project was $928 and $983, respectively.

The smelting and rolling mill companies have project financing totaling $4,311 (reflects principal payments made
through December 31, 2015), of which $1,082 represents Alcoa’s share (the equivalent of Alcoa’s 25.1% interest in the
smelting and rolling mill companies). In conjunction with the financings, Alcoa issued guarantees on behalf of the
smelting and rolling mill companies to the lenders in the event that such companies default on their debt service
requirements through 2017 and 2020 for the smelting company and 2018 and 2021 for the rolling mill company
(Ma’aden issued similar guarantees for its 74.9% interest). Alcoa’s guarantees for the smelting and rolling mill
companies cover total debt service requirements of $142 in principal and up to a maximum of approximately $50 in
interest per year (based on projected interest rates). At December 31, 2015 and 2014, the combined fair value of the
guarantees was $7 and $8, respectively, which was included in Other noncurrent liabilities and deferred credits on the
accompanying Consolidated Balance Sheet.

The mining and refining company has project financing totaling $2,232, of which $560 represents AWAC’s 25.1%
interest in the mining and refining company. In conjunction with the financings, Alcoa, on behalf of AWAC, issued
guarantees to the lenders in the event that the mining and refining company defaults on its debt service requirements
through 2019 and 2024 (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa’s guarantees for the mining
and refining company cover total debt service requirements of $120 in principal and up to a maximum of
approximately $30 in interest per year (based on projected interest rates). At December 31, 2015 and 2014, the
combined fair value of the guarantees was $3 and $4, respectively, which was included in Other noncurrent liabilities
and deferred credits on the accompanying Consolidated Balance Sheet. In the event Alcoa would be required to make
payments under the guarantees, 40% of such amount would be contributed to Alcoa by Alumina Limited, consistent
with its ownership interest in AWAC.

In June 2013, all three joint venture companies entered into a 20-year gas supply agreement with Saudi Aramco,
replacing the previous authorized gas allocation of the Ministry of Petroleum and Mineral Resources of Saudi Arabia
(the “Ministry of Petroleum”). The gas supply agreement provides sufficient fuel to meet manufacturing process
requirements as well as fuel to the adjacent combined water and power plant being constructed by Saline Water
Conversion Corporation, which is owned by the government of Saudi Arabia and is responsible for desalinating sea
water and producing electricity for Saudi Arabia. The combined water and power plant will convert the three joint
venture companies’ gas into electricity and water at cost, which will be supplied to the refinery, smelter, and rolling
mill. A $60 letter of credit previously provided to the Ministry of Petroleum by Ma’aden (Alcoa is responsible for its
pro rata share) under the gas allocation was terminated in June 2015 due to the completion of certain auxiliary rolling
facilities.

The parties subject to the joint venture shareholders’ agreement may not sell, transfer, or otherwise dispose of, pledge,
or encumber any interests in the joint venture until certain milestones have been met as defined in both agreements.
Under the joint venture shareholders’ agreement, upon the occurrence of an unremedied event of default by Alcoa,
Ma’aden may purchase, or, upon the occurrence of an unremedied event of default by Ma’aden, Alcoa may sell, its
interest for consideration that varies depending on the time of the default.

Other Investments. As of December 31, 2015 and 2014, Other investments included $193 and $153, respectively, in
exchange-traded fixed income and equity securities, which are classified as available-for-sale and are carried at fair
value with unrealized gains and losses recognized in other comprehensive income. Unrealized and realized gains and
losses related to these securities were immaterial in 2015, 2014, and 2013.

for as a fair value hedge (see Derivatives in Note X).

The principal amount of long-term debt maturing in each of the next five years is $21 in 2016, $771 in 2017, $1,039 in
2018, $1,140 in 2019, and $1,018 in 2020.

Public Debt—In early 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15,
2014 (the “2014 Notes”) exercised their option to convert the 2014 Notes into 89 million shares of Alcoa common
stock. The conversion rate for the 2014 Notes was 155.4908 shares of Alcoa’s common stock per $1,000 (in full
dollars) principal amount of notes, equivalent to a conversion price of $6.43 per share. The difference between the
$575 principal amount of the 2014 Notes and the $89 par value of the issued shares increased Additional capital on the
accompanying Consolidated Balance Sheet. This transaction was not reflected in the accompanying Statement of
Consolidated Cash Flows as it represents a noncash financing activity.

In September 2014, Alcoa completed a public debt offering under its shelf registration statement for $1,250 of 5.125%
Notes due 2024 (the “2024 Notes”). Alcoa received $1,238 in net proceeds from the public debt offering reflecting an
original issue discount. The net proceeds were used, together with the net proceeds of newly issued mandatory
convertible preferred stock (see Note R), to finance the cash portion of the acquisition of Firth Rixson (see Note F).
The original issue discount was deferred and is being amortized to interest expense over the term of the 2024 Notes.
Interest on the 2024 Notes will be paid semi-annually in April and October, commencing April 2015. Alcoa has the
option to redeem the 2024 Notes, as a whole or in part, at any time or from time to time, on at least 30 days, but not
more than 60 days, prior notice to the holders of the 2024 Notes at a redemption price specified in the 2024 Notes. The
2024 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the
2024 Notes) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2024 Notes
repurchased, plus any accrued and unpaid interest on the 2024 Notes repurchased. The 2024 Notes rank pari passu with
Alcoa’s other unsecured unsubordinated indebtedness.

BNDES Loans—Alcoa Alumínio (Alumínio) has a loan agreement with Brazil’s National Bank for Economic and Social
Development (BNDES) that provides for a financing commitment of $397 (R$687), which is divided into three subloans and
was used to pay for certain expenditures of the Estreito hydroelectric power project. Interest on the three subloans is a Brazil
real rate of interest equal to BNDES’ long-term interest rate, 7.00% and 5.00% as of December 31, 2015 and 2014,
respectively, plus a weighted-average margin of 1.48%. Principal and interest are payable monthly, which began in October
2011 and end in September 2029 for two of the subloans totaling R$667 and began in July 2012 and end in June 2018 for the
subloan of R$20. This loan may be repaid early without penalty with the approval of BNDES.

As of December 31, 2015 and 2014, Alumínio’s outstanding borrowings were $136 (R$522) and $209 (R$560),
respectively, and the weighted-average interest rate was 8.49%. During 2015 and 2014, Alumínio repaid $15 (R$48)
and $20 (R$47), respectively, of outstanding borrowings. Additionally, Alumínio borrowed less than $1 (R$1) and $1
(R$2) under the loan in 2015 and 2014, respectively.

Alumínio has another loan agreement with BNDES that provides for a financing commitment of $85 (R$177), which
also was used to pay for certain expenditures of the Estreito hydroelectric power project. Interest on the loan is a Brazil
real rate of interest equal to BNDES’ long-term interest rate plus a margin of 1.55%. Principal and interest are payable
monthly, which began in January 2013 and end in September 2029. This loan may be repaid early without penalty with
the approval of BNDES. As of December 31, 2015 and 2014, Alumínio’s outstanding borrowings were $38 (R146) and
$58 (R$156), respectively, and the interest rate was 6.55%. During 2015 and 2014, Alumínio repaid $3 (R$10) and $5
(R$11), respectively, of outstanding borrowings.

Credit Facilities. On July 25, 2014, Alcoa entered into a Five-Year Revolving Credit Agreement (the “Credit
Agreement”) with a syndicate of lenders and issuers named therein. The Credit Agreement provides a $4,000 senior
unsecured revolving credit facility (the “Credit Facility”), the proceeds of which are to be used to provide working
capital or for other general corporate purposes of Alcoa. Subject to the terms and conditions of the Credit Agreement,
Alcoa may from time to time request increases in lender commitments under the Credit Facility, not to exceed $500 in
aggregate principal amount, and may also request the issuance of letters of credit, subject to a letter of credit sublimit
of $1,000 under the Credit Facility.

123

The Credit Facility was scheduled to mature on July 25, 2019; however, on July 7, 2015, Alcoa received approval for a
one-year extension of the maturity date by the lenders and issuers that support the Credit Facility. As such, the Credit
Facility now matures on July 25, 2020, unless extended or earlier terminated in accordance with the provisions of the
Credit Agreement. Alcoa may make one additional one-year extension request during the remaining term of the Credit
Facility, subject to the lender consent requirements set forth in the Credit Agreement. Under the provisions of the
Credit Agreement, Alcoa will pay a fee of 0.25% (based on Alcoa’s long-term debt ratings as of December 31, 2015)
of the total commitment per annum to maintain the Credit Facility.

The Credit Facility is unsecured and amounts payable under it will rank pari passu with all other unsecured,
unsubordinated indebtedness of Alcoa. Borrowings under the Credit Facility may be denominated in U.S. dollars or
euros. Loans will bear interest at a base rate or a rate equal to LIBOR, plus, in each case, an applicable margin based on
the credit ratings of Alcoa’s outstanding senior unsecured long-term debt. The applicable margin on base rate loans and
LIBOR loans will be 0.50% and 1.50% per annum, respectively, based on Alcoa’s long-term debt ratings as of
December 31, 2015. Loans may be prepaid without premium or penalty, subject to customary breakage costs.

The Credit Agreement replaces Alcoa’s Five-Year Revolving Credit Agreement, dated as of July 25, 2011 (the
“Former Credit Agreement”), which was scheduled to mature on July 25, 2017. The Former Credit Agreement, which
had a total capacity of $3,750 and was undrawn, was terminated effective July 25, 2014.

The Credit Agreement includes covenants substantially similar to those in the Former Credit Agreement, including,
among others, (a) a leverage ratio, (b) limitations on Alcoa’s ability to incur liens securing indebtedness for borrowed
money, (c) limitations on Alcoa’s ability to consummate a merger, consolidation or sale of all or substantially all of its
assets, and (d) limitations on Alcoa’s ability to change the nature of its business. As of December 31, 2015, Alcoa was
in compliance with all such covenants.

The obligation of Alcoa to pay amounts outstanding under the Credit Facility may be accelerated upon the occurrence
of an “Event of Default” as defined in the Credit Agreement. Such Events of Default include, among others,
(a) Alcoa’s failure to pay the principal of, or interest on, borrowings under the Credit Facility, (b) any representation or
warranty of Alcoa in the Credit Agreement proving to be materially false or misleading, (c) Alcoa’s breach of any of its
covenants contained in the Credit Agreement, and (d) the bankruptcy or insolvency of Alcoa.

There were no amounts outstanding at December 31, 2015 and 2014 and no amounts were borrowed during 2015 or 2014
under the Credit Facility. Also, there were no amounts borrowed during 2014 related to the Former Credit Agreement.

In addition to the Credit Agreement above, Alcoa has a number of other credit agreements that provide a combined borrowing
capacity of $990 as of December 31, 2015, of which $890 is due to expire in 2016 and $100 is due to expire in 2017. The
purpose of any borrowings under these credit arrangements is to provide for working capital requirements and for other general
corporate purposes. The covenants contained in all these arrangements are the same as the Credit Agreement (see above).

In 2015 and 2014, Alcoa borrowed and repaid $1,890 and $1,640, respectively, under the respective credit arrangements.
The weighted-average interest rate and weighted-average days outstanding of the respective borrowings during 2015,
2014, and 2013 were 1.61%, 1.54%, and 1.57%, respectively, and 69 days, 67 days, and 213 days, respectively.

Short-Term Borrowings. At December 31, 2015 and 2014, Short-term borrowings were $38 and $54, respectively.
These amounts included $32 and $50 at December 31, 2015 and 2014, respectively, related to accounts payable
settlement arrangements with certain vendors and third-party intermediaries. These arrangements provide that, at the
vendor’s request, the third-party intermediary advances the amount of the scheduled payment to the vendor, less an
appropriate discount, before the scheduled payment date and Alcoa makes payment to the third-party intermediary on
the date stipulated in accordance with the commercial terms negotiated with its vendors. Alcoa records imputed interest
related to these arrangements in Interest expense on the accompanying Statement of Consolidated Operations.

Commercial Paper. Alcoa had no outstanding commercial paper at December 31, 2015 and 2014. In 2015 and 2014, the
average outstanding commercial paper was $198 and $257, respectively. Commercial paper matures at various times within one
year and had an annual weighted average interest rate of 0.6%, 0.6%, and 0.8% during 2015, 2014, and 2013, respectively.

Alba Matter

Civil Suit. On February 27, 2008, Alcoa Inc. received notice that Aluminium Bahrain B.S.C. (“Alba”) had filed suit
against Alcoa, Alcoa World Alumina LLC (“AWA”), and William Rice (collectively, the “Alcoa Parties”), and others,
in the U.S. District Court for the Western District of Pennsylvania (the “Court”), Civil Action number 08-299, styled
Aluminium Bahrain B.S.C. v. Alcoa Inc., Alcoa World Alumina LLC, William Rice, and Victor Phillip Dahdaleh. The
complaint alleged that certain Alcoa entities and their agents, including Victor Phillip Dahdaleh, had engaged in a
conspiracy over a period of 15 years to defraud Alba. The complaint further alleged that Alcoa and its employees or
agents (1) illegally bribed officials of the government of Bahrain and/or officers of Alba in order to force Alba to
purchase alumina at excessively high prices, (2) illegally bribed officials of the government of Bahrain and/or officers
of Alba and issued threats in order to pressure Alba to enter into an agreement by which Alcoa would purchase an

125

equity interest in Alba, and (3) assigned portions of existing supply contracts between Alcoa and Alba for the sole
purpose of facilitating alleged bribes and unlawful commissions. The complaint alleged that Alcoa and the other
defendants violated the Racketeer Influenced and Corrupt Organizations Act (RICO) and committed fraud. Alba
claimed damages in excess of $1,000. Alba’s complaint sought treble damages with respect to its RICO claims;
compensatory, consequential, exemplary, and punitive damages; rescission of the 2005 alumina supply contract; and
attorneys’ fees and costs.

On October 9, 2012, the Alcoa Parties, without admitting any liability, entered into a settlement agreement with Alba.
The agreement called for AWA to pay Alba $85 in two equal installments, one-half at time of settlement and one-half
one year later, and for the case against the Alcoa Parties to be dismissed with prejudice. Additionally, AWA and Alba
entered into a long-term alumina supply agreement. On October 9, 2012, pursuant to the settlement agreement, AWA
paid Alba $42.5, and all claims against the Alcoa Parties were dismissed with prejudice. On October 9, 2013 pursuant
to the settlement agreement, AWA paid the remaining $42.5. Based on the settlement agreement, in the 2012 third
quarter, Alcoa recorded a $40 charge in addition to the $45 charge it recorded in the 2012 second quarter in respect of
the suit (see Agreement with Alumina Limited below).

Government Investigations. On February 26, 2008, Alcoa Inc. advised the Department of Justice (“DOJ”) and the
Securities and Exchange Commission (“SEC”) that it had recently become aware of the claims by Alba as alleged in
the Alba civil suit, had already begun an internal investigation and intended to cooperate fully in any investigation that
the DOJ or the SEC may commence. On March 17, 2008, the DOJ notified Alcoa that it had opened a formal
investigation. The SEC subsequently commenced a concurrent investigation. Alcoa has been cooperating with the
government since that time.

In the past year, Alcoa had been seeking settlements of both investigations. In the second quarter of 2013, Alcoa
proposed to settle the DOJ matter by offering the DOJ a cash payment of $103. Based on this offer, Alcoa recorded a
charge of $103 in the 2013 second quarter. Also in the second quarter of 2013, Alcoa exchanged settlement offers with
the SEC. However, the SEC staff rejected Alcoa’s offer of $60 and no charge was recorded. During the remainder of
2013, settlement discussions with both the DOJ and the SEC continued.

On January 9, 2014, Alcoa resolved the investigations by the DOJ and the SEC. The settlement with the DOJ was
reached with AWA. Under the terms of a plea agreement entered into with the DOJ, effective January 9, 2014, AWA
pled guilty to one count of violating the anti-bribery provisions of the Foreign Corrupt Practices Act of 1977, as
amended (the “FCPA”). As part of the DOJ resolution, AWA agreed to pay a total of $223, including a fine of $209
payable in five equal installments over four years. The first installment of $41.8, plus a one-time administrative
forfeiture of $14, was paid in the first quarter of 2014, the second installment of $41.8 was paid in the first quarter of
2015, and the remaining installments of $41.8 each will be paid in the first quarters of 2016 through 2018 (the third
installment was paid on January 8, 2016). The DOJ is bringing no case against Alcoa Inc.

Effective January 9, 2014, the Company also settled civil charges filed by the SEC in an administrative proceeding
relating to the anti-bribery, internal controls, and books and records provisions of the FCPA. Under the terms of the
settlement with the SEC, the Company agreed to a settlement amount of $175, but will be given credit for the $14
one-time forfeiture payment, which is part of the DOJ resolution, resulting in a total cash payment to the SEC of $161
payable in five equal installments over four years. The first and second installments of $32.2 each were paid to the SEC
in the first quarter of 2014 and 2015, respectively, and the remaining installments of $32.2 each will be paid in the first
quarters of 2016 through 2018 (the third installment was paid on January 25, 2016).

There was no allegation in the filings by the DOJ and there was no finding by the SEC that anyone at Alcoa Inc.
knowingly engaged in the conduct at issue.

Based on the resolutions with both the DOJ and SEC, in the 2013 fourth quarter, Alcoa recorded a $288 charge, which
includes legal costs of $7, in addition to the $103 charge it recorded in the 2013 second quarter in respect of the
investigations (see Agreement with Alumina Limited below).

126

Agreement with Alumina Limited. AWA is a U.S.-based Alcoa World Alumina and Chemicals (“AWAC”) company
organized under the laws of Delaware that owns, directly or indirectly, alumina refineries and bauxite mines in the
Atlantic region. AWAC is an unincorporated global bauxite mining and alumina refining venture between Alcoa and
Alumina Limited. AWAC consists of a number of affiliated operating entities, including AWA, which own, or have an
interest in, or operate bauxite mines and alumina refineries in eight countries (seven as of December 31, 2014 due to
the divestiture of an ownership interest in a mining and refining joint venture in Jamaica—see Note F). Alcoa owns
60% and Alumina Limited owns 40% of these individual entities, which are consolidated by the Company for financial
reporting purposes.

In October 2012, Alcoa and Alumina Limited entered into an agreement to allocate the costs of the Alba civil
settlement and all legal fees associated with this matter (including the government investigations discussed above)
between Alcoa and Alumina Limited on an 85% and 15% basis, respectively, but this would occur only if a settlement
is reached with the DOJ and the SEC regarding their investigations. As such, the $85 civil settlement in 2012 and all
legal costs associated with the civil suit and government investigations incurred prior to 2013 were allocated on a 60%
and 40% basis in the respective periods on Alcoa’s Statement of Consolidated Operations. As a result of the resolutions
of the government investigations, the $384 charge and legal costs incurred in 2013 were allocated on an 85% and 15%
basis per the allocation agreement with Alumina Limited. Additionally, the $85 civil settlement from 2012 and all legal
costs associated with the civil suit and government investigations incurred prior to 2013 were reallocated on the 85%
and 15% basis. The following table details the activity related to the Alba matter:

Other Matters

On June 5, 2015, AWA and St. Croix Alumina, L.L.C. (“SCA”) filed a complaint in Delaware Chancery Court for a
declaratory judgment and injunctive relief to resolve a dispute between Alcoa and Glencore Ltd. (“Glencore”) with
respect to claimed obligations under a 1995 asset purchase agreement between Alcoa and Glencore. The dispute arose
from Glencore’s demand that Alcoa indemnify it for liabilities it may have to pay to Lockheed Martin (“Lockheed”)
related to the St. Croix alumina refinery. Lockheed had earlier filed suit against Glencore in federal court in New York
seeking indemnity for liabilities it had incurred and would incur to the U.S. Virgin Islands to remediate certain
properties at the refinery property and claimed that Glencore was required by an earlier, 1989 purchase agreement to
indemnify it. Glencore had demanded that Alcoa indemnify and defend it in the Lockheed case and threatened to claim
over against Alcoa in the New York action despite exclusive jurisdiction for resolution of disputes under the 1995
purchase agreement being in Delaware. After Glencore conceded that it was not seeking to add Alcoa to the New York
action, AWA and SCA dismissed their complaint in the Chancery Court case and on August 6, 2015 filed a complaint
for declaratory judgment in Delaware Superior Court. AWA and SCA filed a motion for judgment on the pleadings on
September 16, 2015. Glencore answered AWA’s and SCA’s complaint and asserted counterclaims on August 27, 2015,
and on October 2, 2015 filed its own motion for judgment on the pleadings. Argument on the parties’ motions was held
by the court on December 7, 2015, and by order dated February 8, 2016, Alcoa’s motion was granted and Glencore’s
motion was denied resulting in Alcoa not being liable to indemnify Glencore for the Lockheed action. On February 17,

127

2016, Glencore filed notice of its application for interlocutory appeal of the February 8 ruling. AWA and SCA have 10
days to respond. At this time, the Company is unable to reasonably predict the ultimate outcome for this matter.

Before 2002, Alcoa purchased power in Italy in the regulated energy market and received a drawback of a portion of the
price of power under a special tariff in an amount calculated in accordance with a published resolution of the Italian
Energy Authority, Energy Authority Resolution n. 204/1999 (“204/1999”). In 2001, the Energy Authority published
another resolution, which clarified that the drawback would be calculated in the same manner, and in the same amount, in
either the regulated or unregulated market. At the beginning of 2002, Alcoa left the regulated energy market to purchase
energy in the unregulated market. Subsequently, in 2004, the Energy Authority introduced regulation no. 148/2004, which
set forth a different method for calculating the special tariff that would result in a different drawback for the regulated and
unregulated markets. Alcoa challenged the new regulation in the Administrative Court of Milan and received a favorable
judgment in 2006. Following this ruling, Alcoa continued to receive the power price drawback in accordance with the
original calculation method, through 2009, when the European Commission declared all such special tariffs to be
impermissible “state aid.” In 2010, the Energy Authority appealed the 2006 ruling to the Consiglio di Stato (final court of
appeal). On December 2, 2011, the Consiglio di Stato ruled in favor of the Energy Authority and against Alcoa, thus
presenting the opportunity for the energy regulators to seek reimbursement from Alcoa of an amount equal to the
difference between the actual drawback amounts received over the relevant time period, and the drawback as it would
have been calculated in accordance with regulation 148/2004. On February 23, 2012, Alcoa filed its appeal of the decision
of the Consiglio di Stato (this appeal was subsequently withdrawn in March 2013). On March 26, 2012, Alcoa received a
letter from the agency (Cassa Conguaglio per il Settore Eletrico (CCSE)) responsible for making and collecting payments
on behalf of the Energy Authority demanding payment in the amount of approximately $110 (€85), including interest. By
letter dated April 5, 2012, Alcoa informed CCSE that it disputes the payment demand of CCSE since (i) CCSE was not
authorized by the Consiglio di Stato decisions to seek payment of any amount, (ii) the decision of the Consiglio di Stato
has been appealed (see above), and (iii) in any event, no interest should be payable. On April 29, 2012, Law No. 44 of
2012 (“44/2012”) came into effect, changing the method to calculate the drawback. On February 21, 2013, Alcoa received
a revised request letter from CSSE demanding Alcoa’s subsidiary, Alcoa Trasformazioni S.r.l., make a payment in the
amount of $97 (€76), including interest, which reflects a revised calculation methodology by CCSE and represents the
high end of the range of reasonably possible loss associated with this matter of $0 to $97 (€76). Alcoa has rejected that
demand and has formally challenged it through an appeal before the Administrative Court on April 5, 2013. The
Administrative Court scheduled a hearing for December 19, 2013, which was subsequently postponed until April 17,
2014, and further postponed until June 19, 2014. On this date, the Administrative Court listened to Alcoa’s oral argument,
and on September 2, 2014, rendered its decision. The Administrative Court declared the payment request of CCSE and the
Energy Authority to Alcoa to be unsubstantiated based on the 148/2004 resolution with respect to the January 19, 2007
through November 19, 2009 timeframe. On December 18, 2014, the CCSE and the Energy Authority appealed the
Administrative Court’s September 2, 2014 decision; however, a date for the hearing has not been scheduled. As a result of
the conclusion of the European Commission Matter on January 26, 2016 described below, management has modified its
outlook with respect to a portion of the pending legal proceedings related to this matter. As such, a charge of $37
(€34) was recorded in Restructuring and other charges for the year ended December 31, 2015 on the accompanying
Statement of Consolidated Operations to establish a partial reserve for this matter. At this time, the Company is unable to
reasonably predict the ultimate outcome for this matter.

European Commission Matter. In July 2006, the European Commission (EC) announced that it had opened an
investigation to establish whether an extension of the regulated electricity tariff granted by Italy to some
energy-intensive industries complied with European Union (EU) state aid rules. The Italian power tariff extended the
tariff that was in force until December 31, 2005 through November 19, 2009 (Alcoa had been incurring higher power
costs at its smelters in Italy subsequent to the tariff end date through the end of 2012). The extension was originally
through 2010, but the date was changed by legislation adopted by the Italian Parliament effective on August 15, 2009.
Prior to expiration of the tariff in 2005, Alcoa had been operating in Italy for more than 10 years under a power supply
structure approved by the EC in 1996. That measure provided a competitive power supply to the primary aluminum
industry and was not considered state aid from the Italian Government. The EC’s announcement expressed concerns
about whether Italy’s extension of the tariff beyond 2005 was compatible with EU legislation and potentially distorted
competition in the European market of primary aluminum, where energy is an important part of the production costs.

128

On November 19, 2009, the EC announced a decision in this matter stating that the extension of the tariff by Italy
constituted unlawful state aid, in part, and, therefore, the Italian Government is to recover a portion of the benefit
Alcoa received since January 2006 (including interest). The amount of this recovery was to be based on a calculation
prepared by the Italian Government (see below). In late 2009, after discussions with legal counsel and reviewing the
bases on which the EC decided, including the different considerations cited in the EC decision regarding Alcoa’s two
smelters in Italy, Alcoa recorded a charge of $250 (€173), which included $20 (€14) to write off a receivable from the
Italian Government for amounts due under the now expired tariff structure and $230 (€159) to establish a reserve. On
April 19, 2010, Alcoa filed an appeal of this decision with the General Court of the EU (see below). Prior to 2012,
Alcoa was involved in other legal proceedings related to this matter that separately sought the annulment of the EC’s
July 2006 decision to open an investigation alleging that such decision did not follow the applicable procedural rules
and requested injunctive relief to suspend the effectiveness of the EC’s November 19, 2009 decision. However, the
decisions by the General Court, and subsequent appeals to the European Court of Justice, resulted in the denial of these
remedies.

In June 2012, Alcoa received formal notification from the Italian Government with a calculated recovery amount of
$375 (€303); this amount was reduced by $65 (€53) for amounts owed by the Italian Government to Alcoa, resulting in
a net payment request of $310 (€250). In a notice published in the Official Journal of the European Union on
September 22, 2012, the EC announced that it had filed an action against the Italian Government on July 18, 2012 to
compel it to collect the recovery amount (on October 17, 2013, the European Court of Justice ordered Italy to so
collect). On September 27, 2012, Alcoa received a request for payment in full of the $310 (€250) by October 31, 2012.
Following discussions with the Italian Government regarding the timing of such payment, Alcoa paid the requested
amount in five quarterly installments of $69 (€50) beginning in October 2012 through December 2013.

On October 16, 2014, Alcoa received notice from the General Court of the EU that its April 19, 2010 appeal of the EC’s
November 19, 2009 decision was denied. On December 27, 2014, Alcoa filed an appeal of the General Court’s
October 16, 2014 ruling to the European Court of Justice (ECJ). Following submission of the EC’s response to the appeal,
on June 10, 2015, Alcoa filed a request for an oral hearing before the ECJ; no decision on that request was received. On
January 26, 2016, Alcoa was informed that the ECJ had dismissed Alcoa’s December 27, 2014 appeal of the General
Court’s October 16, 2014 ruling. The dismissal of Alcoa’s appeal represents the conclusion of the legal proceedings in this
matter. Prior to this dismissal, Alcoa had a noncurrent asset of $100 (€91) reflecting the excess of the total of the five
payments made to the Italian Government over the reserve recorded in 2009. As a result, this noncurrent asset, along with
the $58 (€53) for amounts owed by the Italian Government to Alcoa mentioned above plus $6 (€6) for interest previously
paid, was written-off. A charge of $164 (€150) was recorded in Restructuring and other charges for the year ended
December 31, 2015 on the accompanying Statement of Consolidated Operations (see Note D).

As a result of the EC’s November 19, 2009 decision, management had contemplated ceasing operations at its Italian
smelters due to uneconomical power costs. In February 2010, management agreed to continue to operate its smelters in
Italy for up to six months while a long-term solution to address increased power costs could be negotiated. Over a
portion of this time, a long-term solution was not able to be reached related to the Fusina smelter, therefore, in May
2010, Alcoa and the Italian Government agreed to a temporary idling of the Fusina smelter. As of September 30, 2010,
the Fusina smelter was fully curtailed (44,000 metric-tons-per-year). For the Portovesme smelter, Alcoa executed a
new power agreement effective September 1, 2010 through December 31, 2012, replacing the short-term, market-based
power contract that was in effect since early 2010. This new agreement along with interruptibility rights (i.e.
compensation for power interruptions when grids are overloaded) granted to Alcoa for the Portovesme smelter
provided additional time to negotiate a long-term solution (the EC had previously determined that the interruptibility
rights were not considered state aid).

At the end of 2011, as part of a restructuring of Alcoa’s global smelting system, management decided to curtail
operations at the Portovesme smelter during 2012 due to the uncertain prospects for viable, long-term power, along
with rising raw materials costs and falling global aluminum prices (mid-2011 to late 2011). As of December 31, 2012,
the Portovesme smelter was fully curtailed (150,000 metric-tons-per-year).

129

In June 2013 and August 2014, Alcoa decided to permanently shut down and demolish the Fusina and Portovesme
smelters, respectively, due to persistent uneconomical conditions (see Note D).

Environmental Matters. Alcoa participates in environmental assessments and cleanups at more than 100 locations.
These include owned or operating facilities and adjoining properties, previously owned or operating facilities and
adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation
and Liability Act (CERCLA)) sites.

A liability is recorded for environmental remediation when a cleanup program becomes probable and the costs can be
reasonably estimated. As assessments and cleanups proceed, the liability is adjusted based on progress made in
determining the extent of remedial actions and related costs. The liability can change substantially due to factors such
as the nature and extent of contamination, changes in remedial requirements, and technological changes, among others.

Alcoa’s remediation reserve balance was $604 and $543 at December 31, 2015 and 2014 (of which $50 and $70 was
classified as a current liability), respectively, and reflects the most probable costs to remediate identified environmental
conditions for which costs can be reasonably estimated.

In 2015, the remediation reserve was increased by $115 due to a charge of $52 related to the planned demolition of the
remaining structures at the Massena East smelter location (see Note D), a charge of $29 related to the planned
demolition of the Poços de Caldas smelter and the Anglesea power station (see Note D), a charge of $12 related to the
Mosjøen location (see below), a charge of $7 related to the Portovesme location (see below), and a net charge of $15
associated with a number of other sites. In 2014, the remediation reserve was increased by $61 due to a charge of $42
related to the planned demolition of certain structures at the Massena East, NY, Point Henry and Yennora, Australia,
and Portovesme, Italy locations (see Note D), a charge of $3 related to the Portovesme location (see below), and a net
charge of $16 associated with a number of other sites. Of the changes to the remediation reserve in 2015 and 2014, $86
and $47, respectively, was recorded in Restructuring and other charges, while the remainder was recorded in Cost of
goods sold on the accompanying Statement of Consolidated Operations.

Payments related to remediation expenses applied against the reserve were $43 and $46 in 2015 and 2014, respectively.
These amounts include expenditures currently mandated, as well as those not required by any regulatory authority or
third party. In 2015, the change in the reserve also reflects a decrease of $16 due to the effects of foreign currency
translation and an increase of $5 related to the acquisition of Firth Rixson (see Note F). In 2014, the change in the
reserve also reflects an increase of $19 due to the effects of foreign currency translation and a reclassification of
amounts included in other reserves within Other noncurrent liabilities and deferred credits on Alcoa’s Consolidated
Balance Sheet as of December 31, 2013.

Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental
programs. These costs are estimated to be approximately 2% of cost of goods sold.

The following discussion provides details regarding the current status of certain significant reserves related to current
or former Alcoa sites.

Massena West, NY—Alcoa has an ongoing remediation project related to the Grasse River, which is adjacent to
Alcoa’s Massena plant site. Many years ago, it was determined that sediments and fish in the river contain varying
levels of polychlorinated biphenyls (PCBs). The project, which was selected by the U.S. Environmental Protection
Agency (EPA) in a Record of Decision (ROD) issued in April 2013, is aimed at capping PCB contaminated sediments
with concentration in excess of one part per million in the main channel of the river and dredging PCB contaminated
sediments in the near-shore areas where total PCBs exceed one part per million. At December 31, 2015 and 2014, the
reserve balance associated with this matter was $234 and $239, respectively. Alcoa is in the planning and design phase,
which is expected to be completed in 2017. Subsequently in 2017, the actual remediation fieldwork is expected to
commence and take approximately four years. The majority of the project funding is expected to be spent between
2017 and 2021.

130

Sherwin, TX—In connection with the sale of the Sherwin alumina refinery, which was required to be divested as part
of the Reynolds merger in 2000, Alcoa agreed to retain responsibility for the remediation of the then existing
environmental conditions, as well as a pro rata share of the final closure of the active bauxite residue waste disposal
areas (known as the Copano facility). Alcoa’s share of the closure costs is proportional to the total period of operation
of the active waste disposal areas. At December 31, 2015 and 2014, the reserve balance associated with Sherwin was
$30 and $32, respectively. Approximately half of the project funding is expected to be spent through 2019. The
remainder is not expected to be spent in the foreseeable future as it is dependent upon the operating life of the active
waste disposal areas.

East St. Louis, IL—Alcoa has an ongoing remediation project related to an area used for the disposal of bauxite
residue from former alumina refining operations. The project, which was selected by the EPA in a ROD issued in July
2012, is aimed at implementing a soil cover over the affected area. On November 1, 2013, the U.S. Department of
Justice lodged a consent decree on behalf of the EPA for Alcoa to conduct the work outlined in the ROD. This consent
decree was entered as final in February 2014 by the U.S. Department of Justice. As a result, Alcoa began construction
in March 2014; this project is expected to be completed by the end of March 2016 (Alcoa has a second project in East
St. Louis that is separate from the matter presented herein on which Alcoa is expecting an EPA decision in 2016—any
resulting liability is not expected to be material). At December 31, 2015 and 2014, the reserve balance associated with
this matter was $8 and $15, respectively.

Fusina and Portovesme, Italy—In 1996, Alcoa acquired the Fusina smelter and rolling operations and the Portovesme
smelter, both of which are owned by Alcoa’s subsidiary Alcoa Trasformazioni S.r.l. (“Trasformazioni”), from Alumix,
an entity owned by the Italian Government. At the time of the acquisition, Alumix indemnified Alcoa for pre-existing
environmental contamination at the sites. In 2004, the Italian Ministry of Environment and Protection of Land and Sea
(MOE) issued orders to Trasformazioni and Alumix for the development of a clean-up plan related to soil
contamination in excess of allowable limits under legislative decree and to institute emergency actions and pay natural
resource damages. Trasformazioni appealed the orders and filed suit against Alumix, among others, seeking
indemnification for these liabilities under the provisions of the acquisition agreement. In 2009, Ligestra S.r.l.
(“Ligestra”), Alumix’s successor, and Trasformazioni agreed to a stay of the court proceedings while investigations
were conducted and negotiations advanced towards a possible settlement.

In December 2009, Trasformazioni and Ligestra reached an initial agreement for settlement of the liabilities related to
Fusina while negotiations continued related to Portovesme (see below). The agreement outlined an allocation of
payments to the MOE for emergency action and natural resource damages and the scope and costs for a proposed soil
remediation project, which was formally presented to the MOE in mid-2010. The agreement was contingent upon final
acceptance of the remediation project by the MOE. As a result of entering into this agreement, Alcoa increased the
reserve by $12 in 2009 for Fusina. Based on comments received from the MOE and local and regional environmental
authorities, Trasformazioni submitted a revised remediation plan in the first half of 2012; however, such revisions did
not require any change to the existing reserve. In October 2013, the MOE approved the project submitted by Alcoa,
resulting in no adjustment to the reserve.

In January 2014, in anticipation of Alcoa reaching a final administrative agreement with the MOE, Alcoa and Ligestra
entered into a final agreement related to Fusina for allocation of payments to the MOE for emergency action and
natural resource damages and the costs for the approved soil remediation project. The agreement resulted in Ligestra
assuming 50% to 80% of all payments and remediation costs. On February 27, 2014, Alcoa and the MOE reached a
final administrative agreement for conduct of work. The agreement includes both a soil and groundwater remediation
project estimated to cost $33 (€24) and requires payments of $25 (€18) to the MOE for emergency action and natural
resource damages. The remediation projects are slated to begin as soon as Alcoa receives final approval from the
Ministry of Infrastructure. Based on the final agreement with Ligestra, Alcoa’s share of all costs and payments is $17
(€12), of which $9 (€6) related to the damages will be paid annually over a 10-year period, which began in April 2014,
and was previously fully reserved.

131

Separately, in 2009, due to additional information derived from the site investigations conducted at Portovesme, Alcoa
increased the reserve by $3. In November 2011, Trasformazioni and Ligestra reached an agreement for settlement of
the liabilities related to Portovesme, similar to the one for Fusina. A proposed soil remediation project for Portovesme
was formally presented to the MOE in June 2012. Neither the agreement with Ligestra nor the proposal to the MOE
resulted in a change to the reserve for Portovesme. In November 2013, the MOE rejected the proposed soil remediation
project and requested a revised project be submitted. In May 2014, Trasformazioni and Ligestra submitted a revised
soil remediation project that addressed certain stakeholders’ concerns. Alcoa increased the reserve by $3 in 2014 to
reflect the estimated higher costs associated with the revised soil remediation project, as well as current operating and
maintenance costs of the Portovesme site.

In October 2014, the MOE required a further revised project be submitted to reflect the removal of a larger volume of
contaminated soil than what had been proposed, as well as design changes for the cap related to the remaining contaminated
soil left in place and the expansion of an emergency containment groundwater pump and treatment system that was
previously installed. Trasformazioni and Ligestra submitted the further revised soil remediation project in February 2015. As
a result, Alcoa increased the reserve by $7 in March 2015 to reflect the increase in the estimated costs of the project. In
October 2015, Alcoa received a final ministerial decree approving the February 2015 revised soil remediation project. Work
on the soil remediation project will commence in 2016 and is expected to be completed in 2019. Alcoa and Ligestra are now
working on a final groundwater remediation project, which will be submitted to the MOE for review during 2016. The
ultimate outcome of this matter may result in a change to the existing reserve for Portovesme.

Baie Comeau, Quebec, Canada—In August 2012, Alcoa presented an analysis of remediation alternatives to the
Quebec Ministry of Sustainable Development, Environment, Wildlife and Parks (MDDEP), in response to a previous
request, related to known PCBs and polycyclic aromatic hydrocarbons (PAHs) contained in sediments of the Anse du
Moulin bay. As such, Alcoa increased the reserve for Baie Comeau by $25 in 2012 to reflect the estimated cost of
Alcoa’s recommended alternative, consisting of both dredging and capping of the contaminated sediments. In July
2013, Alcoa submitted the Environmental Impact Assessment for the project to the MDDEP. The MDDEP notified
Alcoa that the project as it was submitted was approved and a final mistrial decree was issued in July 2015. As a result,
no further adjustment to the reserve was required in 2015. The decree provides final approval for the project and allows
Alcoa to start work on the final project design, which is expected to be completed in 2016 with construction on the
project expected to begin in 2017. Completion of the final project design and bidding of the project may result in
additional liability in a future period.

Mosjøen, Norway—In September 2012, Alcoa presented an analysis of remediation alternatives to the Norwegian
Environmental Agency (NEA) (formerly the Norwegian Climate and Pollution Agency, or “Klif”), in response to a
previous request, related to known PAHs in the sediments located in the harbor and extending out into the fjord. As
such, Alcoa increased the reserve for Mosjøen by $20 in 2012 to reflect the estimated cost of the baseline alternative
for dredging of the contaminated sediments. A proposed project reflecting this alternative was formally presented to
the NEA in June 2014, and was resubmitted in late 2014 to reflect changes by the NEA. The revised proposal did not
result in a change to the reserve for Mosjøen.

In April 2015, the NEA notified Alcoa that the revised project was approved and required submission of the final
project design before issuing a final order. Alcoa completed and submitted the final project design, which identified a
need to stabilize the related wharf structure to allow for the sediment dredging in the harbor. As a result, Alcoa
increased the reserve for Mosjøen by $11 in June 2015 to reflect the estimated cost of the wharf stabilization. Also in
June 2015, the NEA issued a final order approving the project as well as the final project design. In September 2015,
Alcoa increased the reserve by $1 to reflect the potential need (based on prior experience with similar projects) to
perform additional dredging if the results of sampling, which is required by the order, don’t achieve the required
cleanup levels. Project construction will commence in 2016 and is expected to be completed by the end of 2017.

132

Tax. In September 2010, following a corporate income tax audit covering the 2003 through 2005 tax years, an
assessment was received as a result of Spain’s tax authorities disallowing certain interest deductions claimed by a
Spanish consolidated tax group owned by the Company. An appeal of this assessment in Spain’s Central Tax
Administrative Court by the Company was denied in October 2013. In December 2013, the Company filed an appeal of
the assessment in Spain’s National Court.

Additionally, following a corporate income tax audit of the same Spanish tax group for the 2006 through 2009 tax
years, Spain’s tax authorities issued an assessment in July 2013 similarly disallowing certain interest deductions. In
August 2013, the Company filed an appeal of this second assessment in Spain’s Central Tax Administrative Court,
which was denied in January 2015. The Company filed an appeal of this second assessment in Spain’s National Court
in March 2015.

The combined assessments (remeasured for a tax rate change enacted in November 2014—see Note T) total $263
(€241). The Company believes it has meritorious arguments to support its tax position and intends to vigorously litigate
the assessments through Spain’s court system. However, in the event the Company is unsuccessful, a portion of the
assessments may be offset with existing net operating losses available to the Spanish consolidated tax group.
Additionally, it is possible that the Company may receive similar assessments for tax years subsequent to 2009. At this
time, the Company is unable to reasonably predict an outcome for this matter.

In March 2013, Alcoa’s subsidiary, Alcoa World Alumina Brasil (AWAB), was notified by the Brazilian Federal
Revenue Office (RFB) that approximately $110 (R$220) of value added tax credits previously claimed are being
disallowed and a penalty of 50% assessed. Of this amount, AWAB received $41 (R$82) in cash in May 2012. The
value added tax credits were claimed by AWAB for both fixed assets and export sales related to the Juruti bauxite mine
and São Luís refinery expansion. The RFB has disallowed credits they allege belong to the consortium in which
AWAB owns an interest and should not have been claimed by AWAB. Credits have also been disallowed as a result of
challenges to apportionment methods used, questions about the use of the credits, and an alleged lack of documented
proof. AWAB presented defense of its claim to the RFB on April 8, 2013. If AWAB is successful in this administrative
process, the RFB would have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a
judicial level. Separately from the AWAB’s administrative appeal, in June 2015, new tax law was enacted repealing
the provisions in the tax code that were the basis for the RFB assessing a 50% penalty in this matter. As such, the
estimated range of reasonably possible loss is $0 to $27 (R$103), whereby the maximum end of this range represents
the portion of the disallowed credits applicable to the export sales and excludes the 50% penalty. Additionally, the
estimated range of disallowed credits related to AWAB’s fixed assets is $0 to $30 (R$117), which would increase the
net carrying value of AWAB’s fixed assets if ultimately disallowed. It is management’s opinion that the allegations
have no basis; however, at this time, management is unable to reasonably predict an outcome for this matter.

Between 2000 and 2002, Alcoa Alumínio (Alumínio) sold approximately 2,000 metric tons of metal per month from its
Poços de Caldas facility, located in the State of Minas Gerais (the “State”), to Alfio, a customer also located in the
State. Sales in the State were exempted from value-added tax (VAT) requirements. Alfio subsequently sold metal to
customers outside of the State, but did not pay the required VAT on those transactions. In July 2002, Alumínio
received an assessment from State auditors on the theory that Alumínio should be jointly and severally liable with
Alfio for the unpaid VAT. In June 2003, the administrative tribunal found Alumínio liable, and Alumínio filed a
judicial case in the State in February 2004 contesting the finding. In May 2005, the Court of First Instance found
Alumínio solely liable, and a panel of a State appeals court confirmed this finding in April 2006. Alumínio filed a
special appeal to the Superior Tribunal of Justice (STJ) in Brasilia (the federal capital of Brazil) later in 2006. In 2011,
the STJ (through one of its judges) reversed the judgment of the lower courts, finding that Alumínio should neither be
solely nor jointly and severally liable with Alfio for the VAT, which ruling was then appealed by the State. In August
2012, the STJ agreed to have the case reheard before a five-judge panel. A decision from this panel is pending, but
additional appeals are likely. At December 31, 2015, the assessment totaled $35 (R$135), including penalties and
interest. While the Company believes it has meritorious defenses, the Company is unable to reasonably predict an
outcome.

133

Other. In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be
instituted or asserted against Alcoa, including those pertaining to environmental, product liability, safety and health,
and tax matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot now
be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity
or results of operations in a particular period could be materially affected by one or more of these other matters.
However, based on facts currently available, management believes that the disposition of these other matters that are
pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of
the Company.

Commitments

Investments. Alumínio, a wholly-owned subsidiary of Alcoa, is a participant in four consortia that each owns a
hydroelectric power project in Brazil. The purpose of Alumínio’s participation is to increase its energy self-sufficiency
and provide a long-term, low-cost source of power for its two smelters (see below) and one refinery. These projects are
known as Machadinho, Barra Grande, Serra do Facão, and Estreito.

Alumínio committed to taking a share of the output of the Machadinho and Barra Grande projects each for 30 years
and the Serra do Facão and Estreito projects each for 26 years at cost (including cost of financing the project). In the
event that other participants in any of these projects fail to fulfill their financial responsibilities, Alumínio may be
required to fund a portion of the deficiency. In accordance with the respective agreements, if Alumínio funds any such
deficiency, its participation and share of the output from the respective project will increase proportionately.

The Machadinho project reached full capacity in 2002. Alumínio’s investment in this project is 30.99%, which entitles
Alumínio to approximately 120 megawatts of assured power. The Machadinho consortium is an unincorporated joint
venture, and, therefore, Alumínio’s share of the assets and liabilities of the consortium are reflected in the respective
lines on the accompanying Consolidated Balance Sheet.

The Barra Grande project reached full capacity in 2006. Alumínio’s investment in this project is 42.18% and is
accounted for under the equity method. This entitles Alumínio to approximately 160 megawatts of assured power.
Alumínio’s total investment in this project was $94 (R$374) and $132 (R$355) at December 31, 2015 and 2014,
respectively.

The Serra do Facão project reached full capacity in 2010. Alumínio’s investment in this project is 34.97% and is
accounted for under the equity method. This entitles Alumínio to approximately 65 megawatts of assured power.
Alumínio’s total investment in this project was $52 (R$208) and $66 (R$178) at December 31, 2015 and 2014,
respectively.

The Estreito project reached full capacity in March 2013. Alumínio’s investment in this project is 25.49%, which
entitles Alumínio to approximately 150 megawatts of assured power. The Estreito consortium is an unincorporated
joint venture, and, therefore, Alumínio’s share of the assets and liabilities of the consortium are reflected in the
respective lines on the accompanying Consolidated Balance Sheet. As of December 31, 2015, construction of the
Estreito project is essentially complete.

Prior to October 2013, Alumínio’s power self-sufficiency satisfied approximately 70% of a total energy demand of
approximately 690 megawatts from two smelters (São Luís (Alumar) and Poços de Caldas) and one refinery (Poços de
Caldas) in Brazil. Since that time, the total energy demand has declined by approximately 675 megawatts due to
capacity curtailments of both smelters in both 2013 and 2014, as well as the eventual permanent closure of the Poços
de Caldas smelter in 2015.

In 2004, Alcoa acquired a 20% interest in a consortium, which subsequently purchased the Dampier to Bunbury
Natural Gas Pipeline (DBNGP) in Western Australia, in exchange for an initial cash investment of $17 (A$24). The
investment in the DBNGP, which is classified as an equity investment, was made in order to secure a competitively
priced long-term supply of natural gas to Alcoa’s refineries in Western Australia. Alcoa made additional contributions
of $141 (A$176) for its share of the pipeline capacity expansion and other operational purposes of the consortium
through September 2011. No further expansion of the pipeline’s capacity is planned at this time. In late 2011, the
consortium initiated a three-year equity call plan to improve its capitalization structure. This plan required Alcoa to
contribute $39 (A$40), all of which was made through December 31, 2014. Following the completion of the three-year
equity call plan in December 2014, the consortium initiated a new equity call plan to further improve its capitalization
structure. This plan requires Alcoa to contribute $30 (A$36) through mid 2016, of which $17 (A$22) was made
through December 31, 2015, including $16 (A$21) in 2015. In addition to its equity ownership, Alcoa has an
agreement to purchase gas transmission services from the DBNGP. At December 31, 2015, Alcoa has an asset of $268
(A$368) representing prepayments made under the agreement for future gas transmission services. Alcoa’s maximum
exposure to loss on the investment and the related contract is approximately $380 (A$520) as of December 31, 2015.

On April 8, 2015, Alcoa’s majority-owned subsidiary, Alcoa of Australia Limited (AofA), which is part of AWAC,
secured a new 12-year gas supply agreement to power its three alumina refineries in Western Australia beginning in
July 2020. This agreement was conditional on the completion of a third-party acquisition of the related energy assets
from the then-current owner, which occurred in June 2015. The terms of AofA’s gas supply agreement require a
prepayment of $500 to be made in two installments. The first installment of $300 was made at the time of the
completion of the third-party acquisition and the second installment of $200 will be made in April 2016 (previously
was scheduled in January 2016). At December 31, 2015, Alcoa has an asset of $288 (A$395), which was included in
Other noncurrent assets on the accompanying Consolidated Balance Sheet, representing the first installment.

Purchase Obligations. Alcoa is party to unconditional purchase obligations for energy that expire between 2018 and
2036. Commitments related to these contracts total $74 in 2016, $130 in 2017, $133 in 2018, $126 in 2019, $129 in
2020, and $1,711 thereafter. Expenditures under these contracts totaled $131 in 2015, $178 in 2014, and $163 in 2013.
Additionally, Alcoa has entered into other purchase commitments for energy, raw materials, and other goods and
services, which total $3,015 in 2016, $1,807 in 2017, $1,569 in 2018, $1,496 in 2019, $1,401 in 2020, and $13,251
thereafter.

Operating Leases. Certain land and buildings, alumina refinery process control technology, plant equipment, vehicles,
and computer equipment are under operating lease agreements. Total expense for all leases was $210 in 2015, $227 in
2014, and $232 in 2013. Under long-term operating leases, minimum annual rentals are $243 in 2016, $168 in 2017,
$130 in 2018, $100 in 2019, $74 in 2020, and $138 thereafter.

Guarantees. At December 31, 2015, Alcoa has maximum potential future payments for guarantees issued on behalf of
a third party of $478. These guarantees expire at various times between 2017 and 2024 and relate to project financing
for the aluminum complex in Saudi Arabia (see Note I). Alcoa also has outstanding bank guarantees related to tax
matters, outstanding debt, workers compensation, environmental obligations, energy contracts, and customs duties,
among others. The total amount committed under these guarantees, which expire at various dates between 2016 and
2023 was $320 at December 31, 2015.

Letters of Credit. Alcoa has outstanding letters of credit primarily related to workers’ compensation, energy contracts
(including $200 related to an expected April 2016 prepayment under a gas supply contract—see Investments above),
and leasing obligations. The total amount committed under these letters of credit, which automatically renew or expire
at various dates, mostly in 2016, was $510 at December 31, 2015.

Surety Bonds. Alcoa has outstanding surety bonds primarily related to tax matters, contract performance, workers
compensation, environmental-related matters, and customs duties. The total amount committed under these bonds,
which automatically renew or expire at various dates, mostly in 2016, was $159 at December 31, 2015.

Noncash Financing and Investing Activities. In July 2015, Alcoa purchased all outstanding shares of RTI common
stock in a stock-for-stock transaction valued at $870 (see Note F). As a result, Alcoa issued 87 million shares of its
common stock to consummate this transaction, which was not reflected in the accompanying Statement of
Consolidated Cash Flows as it represents a noncash financing activity.

In early 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 (the “2014
Notes”) exercised their option to convert the 2014 Notes into 89 million shares of Alcoa common stock (see Note K).
This transaction was not reflected in the accompanying Statement of Consolidated Cash Flows as it represents a
noncash financing activity.

In late 2014, Alcoa paid $2,995 (net of cash acquired) to acquire Firth Rixson (see Note F). A portion of this
consideration was paid through the issuance of 37 million shares in Alcoa common stock valued at $610. The issuance
of common stock was not reflected in the accompanying Statement of Consolidated Cash Flows as it represents a
noncash investing activity.

Q. Segment and Geographic Area Information

Alcoa is primarily a producer of aluminum products. Aluminum and alumina represent approximately 80% of Alcoa’s
revenues. Nonaluminum products include precision castings and aerospace and industrial fasteners. Alcoa’s products
are used worldwide in transportation (including aerospace, automotive, truck, trailer, rail, and shipping), packaging,
building and construction, oil and gas, defense, and industrial applications. Alcoa’s segments are organized by product
on a worldwide basis. Segment performance under Alcoa’s management reporting system is evaluated based on a
number of factors; however, the primary measure of performance is the after-tax operating income (ATOI) of each
segment. Certain items such as the impact of LIFO inventory accounting; metal price lag (see below); interest expense;
noncontrolling interests; corporate expense (general administrative and selling expenses of operating the corporate
headquarters and other global administrative facilities, along with depreciation and amortization on corporate-owned
assets); restructuring and other charges; and other items, including intersegment profit eliminations, differences
between tax rates applicable to the segments and the consolidated effective tax rate, and other nonoperating items such
as foreign currency transaction gains/losses and interest income are excluded from segment ATOI. Segment assets
exclude, among others, cash and cash equivalents; deferred income taxes; goodwill not allocated to businesses for
segment reporting purposes; corporate fixed assets; and LIFO reserves.

The accounting policies of the segments are the same as those described in the Summary of Significant Accounting
Policies (see Note A). Transactions among segments are established based on negotiation among the parties.
Differences between segment totals and Alcoa’s consolidated totals for line items not reconciled are in Corporate.

Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the
Global Rolled Products and Engineered Products and Solutions (now Engineered Products and Solutions and
Transportation and Construction Solutions—see below) segments in order to enhance the visibility of the underlying
operating performance of these businesses. Metal price lag describes the timing difference created when the average
price of metal sold differs from the average cost of the metal when purchased by the respective segment. In general,
when the price of metal increases, metal price lag is favorable, and when the price of metal decreases, metal price lag is
unfavorable. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total
segment ATOI to consolidated net (loss) income attributable to Alcoa. As a result, this change does not impact the
consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change.

In the third quarter of 2015, management approved a realignment of Alcoa’s Engineered Products and Solutions
segment due to the expansion of this part of Alcoa’s business portfolio through both organic and inorganic growth.
This realignment consisted of moving both the Alcoa Wheel and Transportation Products and Building and
Construction Systems business units to a new reportable segment named Transportation and Construction Solutions.
Additionally, the Latin American soft alloy extrusions business previously included in Corporate was moved into the
new Transportation and Construction Solutions segment. The remaining Engineered Products and Solutions segment
consists of the Alcoa Fastening Systems and Rings (renamed to include portions of the Firth Rixson business acquired
in November 2014), Alcoa Power and Propulsion (includes the TITAL business acquired in March 2015), Alcoa
Forgings and Extrusions (includes the other portions of Firth Rixson), and Alcoa Titanium and Engineered Products (a
new business unit that consists solely of the RTI International Metals business acquired in July 2015) business units.
Segment information for all prior periods presented was updated to reflect the new segment structure.

Alcoa’s operations consist of five worldwide reportable segments as follows:

Alumina. This segment represents a portion of Alcoa’s upstream operations and consists of the Company’s worldwide
refining system. Alumina mines bauxite, from which alumina is produced and then sold directly to external smelter
customers, as well as to the Primary Metals segment (see Primary Metals below), or to customers who process it into
industrial chemical products. More than half of Alumina’s production is sold under supply contracts to third parties
worldwide, while the remainder is used internally by the Primary Metals segment. Alumina produced by this segment
and used internally is transferred to the Primary Metals segment at prevailing market prices. A portion of this
segment’s third-party sales are completed through the use of agents, alumina traders, and distributors.

137

Primary Metals. This segment represents a portion of Alcoa’s upstream operations and consists of the Company’s
worldwide smelting system. Primary Metals purchases alumina, mostly from the Alumina segment (see Alumina
above), from which primary aluminum is produced and then sold directly to external customers and traders, as well as
to Alcoa’s midstream operations and, to a lesser extent, downstream operations. Results from the sale of aluminum
powder, scrap, and excess energy are also included in this segment, as well as the results of aluminum derivative
contracts and buy/resell activity. Primary aluminum produced by Alcoa and used internally is transferred to other
segments at prevailing market prices. The sale of primary aluminum represents approximately 90% of this segment’s
third-party sales. Buy/resell activity occurs when this segment purchases metal and resells such metal to external
customers or the midstream and downstream operations in order to maximize smelting system efficiency and to meet
customer requirements.

Global Rolled Products. This segment represents Alcoa’s midstream operations and produces aluminum sheet and
plate for a variety of end markets. Approximately one-half of the third-party shipments in this segment consist of sheet
sold directly to customers in the packaging end market for the production of aluminum cans (beverage, food, and pet
food). Seasonal increases in can sheet sales are generally experienced in the second and third quarters of the year. This
segment also includes sheet and plate sold directly to customers and through distributors related to the aerospace,
automotive, commercial transportation, building and construction, and industrial products (mainly used in the
production of machinery and equipment and consumer durables) end markets. A small portion of this segment also
produces aseptic foil for the packaging end market. While the customer base for flat-rolled products is large, a
significant amount of sales of sheet and plate is to a relatively small number of customers.

Engineered Products and Solutions. This segment represents a portion of Alcoa’s downstream operations and
produces products that are used mostly in the aerospace (commercial and defense), commercial transportation, and
power generation end markets. Such products include fastening systems (titanium, steel, and nickel alloys) and
seamless rolled rings (mostly nickel alloys); and investment castings (nickel super alloys, titanium, and aluminum),
including airfoils and forged jet engine components (e.g., jet engine disks), all of which are sold directly to customers
and through distributors. More than 70% of the third-party sales in this segment are from the aerospace end market. A
small part of this segment also produces various forging and extrusion metal products for the oil and gas, industrial
products, automotive, and land and sea defense end markets. Seasonal decreases in sales are generally experienced in
the third quarter of the year due to the European summer slowdown across all end markets.

Transportation and Construction Solutions. This segment represents a portion of Alcoa’s downstream operations
and produces products that are used mostly in the nonresidential building and construction and commercial
transportation end markets. Such products include integrated aluminum structural systems, architectural extrusions, and
forged aluminum commercial vehicle wheels, which are sold directly to customers and through distributors. A small
part of this segment also produces aluminum products for the industrial products end market.

R. Preferred and Common Stock

Preferred Stock. Alcoa has two classes of preferred stock: Class A Preferred Stock and Class B Serial Preferred
Stock. Class A Preferred Stock has 660,000 shares authorized at a par value of $100 per share with an annual $3.75
cumulative dividend preference per share. There were 546,024 of such shares outstanding at December 31, 2015 and
2014. Class B Serial Preferred Stock has 10 million shares authorized at a par value of $1 per share. There were
2.5 million of such shares outstanding at December 31, 2015 and 2014 (see below).

141

In September 2014, Alcoa completed a public offering under its shelf registration statement for $1,250 of 25 million
depositary shares, each of which represents a 1/10th interest in a share of Alcoa’s 5.375% Class B Mandatory
Convertible Preferred Stock, Series 1, par value $1 per share, liquidation preference $500 per share (the “Mandatory
Convertible Preferred Stock”). The 25 million depositary shares are equivalent to 2.5 million shares of Mandatory
Convertible Preferred Stock. Each depositary share entitles the holder, through the depositary, to a proportional
fractional interest in the rights and preferences of a share of Mandatory Convertible Preferred Stock, including
conversion, dividend, liquidation, and voting rights, subject to terms of the deposit agreement. Alcoa received $1,213
in net proceeds from the public offering reflecting an underwriting discount. The net proceeds were used, together with
the net proceeds of issued debt (see Note K), to finance the cash portion of the acquisition of Firth Rixson (see Note F).
The underwriting discount was recorded as a decrease to Additional capital on the accompanying Consolidated Balance
Sheet.

The Mandatory Convertible Preferred Stock constitutes a series of Alcoa’s Class B Serial Preferred Stock, which ranks
senior to Alcoa’s common stock and junior to Alcoa’s Class A Preferred Stock and existing and future indebtedness.
Dividends on the Mandatory Convertible Preferred Stock are cumulative in nature and are paid at the rate of $26.8750
per annum per share, which commenced January 1, 2015 (paid on December 30, 2014). Holders of the Mandatory
Convertible Preferred Stock generally have no voting rights.

On the mandatory conversion date, October 1, 2017, all outstanding shares of Mandatory Convertible Preferred Stock
will automatically convert into shares of Alcoa’s common stock. Based on the Applicable Market Value (as defined in
the terms of the Mandatory Convertible Preferred Stock) of Alcoa’s common stock on the mandatory conversion date,
each share of Mandatory Convertible Preferred Stock will be convertible into not more than 30.9406 shares of common
stock and not less than 25.7838 shares of common stock, subject to certain anti-dilution and other adjustments as
described in the terms of the Mandatory Convertible Preferred Stock. At any time prior to October 1, 2017, a holder
may elect to convert shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than
one share of Mandatory Convertible Preferred Stock), at the minimum conversion rate of 25.7838 shares of common
stock, subject to certain anti-dilution and other adjustments as described in the terms of the Mandatory Convertible
Preferred Stock. Alcoa does not have the right to redeem the Mandatory Convertible Preferred Stock.

If Alcoa undergoes a fundamental change, as defined in the terms of the Mandatory Convertible Preferred Stock,
holders may elect to convert their Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than
one share of Mandatory Convertible Preferred Stock), into shares of Alcoa’s common stock. The per share conversion
rate under a fundamental change is not less than 25.2994 shares of common stock and not more than 30.9406 shares of
common stock. Holders who elect to convert will also receive any accumulated and unpaid dividends and a
Fundamental Change Dividend Make-whole Amount (as defined in the terms of the Mandatory Convertible Preferred
Stock) equal to the present value of all remaining dividend payments on the Mandatory Convertible Preferred Stock.

Common Stock. There are 1.8 billion shares authorized at a par value of $1 per share, and 1,391,211,244 and
1,303,813,830 shares, respectively, were issued at December 31, 2015 and 2014. The current dividend yield as
authorized by Alcoa’s Board of Directors is $0.12 per annum or $0.03 per quarter.

In July 2015, Alcoa issued 87 million shares of common stock as consideration paid to acquire RTI (see Note F).

In early 2014, Alcoa issued 89 million shares of common stock under the terms of Alcoa’s 5.25% Convertible Notes
due March 15, 2014 (see Note K). Also, in November 2014, Alcoa issued 37 million shares of common stock as part of
the consideration paid to acquire an aerospace business, Firth Rixson (see Note F).

142

As of December 31, 2015, 77 million shares of common stock were reserved for issuance under Alcoa’s stock-based
compensation plans, respectively. Alcoa issues shares from treasury stock to satisfy the exercise of stock options and
the conversion of stock awards.

Alcoa has a stock-based compensation plan under which stock options and stock awards are granted in January each
year to eligible employees. Most plan participants can choose whether to receive their award in the form of stock
options, stock awards, or a combination of both. This choice is made before the grant is issued and is irrevocable. Stock
options are granted at the closing market price of Alcoa’s common stock on the date of grant and vest over a three-year
service period (1/3 each year) with a ten-year contractual term. Stock awards also vest over a three-year service period
from the date of grant and certain of these awards also include performance conditions. In 2015, 2014, and 2013, the
final number of performance stock awards earned will be based on Alcoa’s achievement of sales and profitability
targets over the respective three-year period. One-third of the award will be earned each year based on the performance
against the pre-established targets for that year. The performance stock awards earned over the three-year period vest at
the end of the third year.

In 2015, 2014, and 2013, Alcoa recognized stock-based compensation expense of $92 ($61 after-tax), $87 ($58 after-
tax), and $71 ($48 after-tax), respectively, of which approximately 80%, 80%, and 70%, respectively, related to stock
awards (there was no stock-based compensation expense capitalized in 2015, 2014, or 2013). At December 31, 2015,
there was $71 (pretax) of unrecognized compensation expense related to non-vested stock option grants and non-vested
stock award grants. This expense is expected to be recognized over a weighted average period of 1.6 years. As part of
Alcoa’s stock-based compensation plan design, individuals who are retirement-eligible have a six-month requisite
service period in the year of grant. As a result, a larger portion of expense will be recognized in the first half of each
year for these retirement-eligible employees. Of the total pretax compensation expense recognized in 2015, 2014, and
2013, $17, $15, and $14, respectively, pertains to the acceleration of expense related to retirement-eligible employees.

Stock-based compensation expense is based on the grant date fair value of the applicable equity grant. For stock
awards, the fair value was equivalent to the closing market price of Alcoa’s common stock on the date of grant. For
stock options, the fair value was estimated on the date of grant using a lattice-pricing model, which generated a result
of $4.47, $2.84, and $2.24 per option in 2015, 2014, and 2013, respectively. The lattice-pricing model uses a number of
assumptions to estimate the fair value of a stock option, including an average risk-free interest rate, dividend yield,
volatility, exercise behavior, and contractual life. The following paragraph describes in detail the assumptions used to
estimate the fair value of stock options granted in 2015 (the assumptions used to estimate the fair value of stock options
granted in 2014 and 2013 were not materially different).

143

The range of average risk-free interest rates (0.07-1.83%) was based on a yield curve of interest rates at the time of the
grant based on the contractual life of the option. The dividend yield (0.8%) was based on a one-year average. Volatility
(32-41%) was based on historical and implied volatilities over the term of the option. Alcoa utilized historical option
forfeiture data to estimate annual pre- and post-vesting forfeitures (7%). Exercise behavior (50%) was based on a
weighted average exercise ratio (exercise patterns for grants issued over the number of years in the contractual option
term) of an option’s intrinsic value resulting from historical employee exercise behavior. Based upon the other
assumptions used in the determination of the fair value, the life of an option (5.9 years) was an output of the lattice-pricing
model. The activity for stock options and stock awards during 2015 was as follows (options and awards in millions):

As of December 31, 2015, the number of stock options outstanding had a weighted average remaining contractual life
of 6.08 years and a total intrinsic value of $8. Additionally, 23.3 million of the stock options outstanding were fully
vested and exercisable and had a weighted average remaining contractual life of 5.25 years, a weighted average
exercise price of $11.82, and a total intrinsic value of $5 as of December 31, 2015. In 2015, 2014, and 2013, the cash
received from stock option exercises was $25, $150, and $13 and the total tax benefit realized from these exercises was
$6, $28, and $1, respectively. The total intrinsic value of stock options exercised during 2015, 2014, and 2013 was $19,
$84, and $2, respectively.

S. Earnings Per Share

Basic earnings per share (EPS) amounts are computed by dividing earnings, after the deduction of preferred stock
dividends declared by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of
common stock for all potentially dilutive share equivalents outstanding.

The information used to compute basic and diluted EPS attributable to Alcoa common shareholders was as follows
(shares in millions):

Net (loss) income attributable to Alcoa
Less: preferred stock dividends declared
Net (loss) income available to Alcoa common shareholders—basic
Add: dividends related to mandatory convertible preferred stock
Add: interest expense related to convertible notes
Net (loss) income available to Alcoa common shareholders—diluted
Average shares outstanding—basic
Effect of dilutive securities:

Stock options
Stock and performance awards
Mandatory convertible preferred stock
Convertible notes

Average shares outstanding—diluted

In 2015, basic average shares outstanding and diluted average shares outstanding were the same because the effect of
potential shares of common stock was anti-dilutive since Alcoa generated a net loss. As a result, 77 million share
equivalents related to mandatory convertible preferred were not included in the computation of diluted EPS.
Additionally, 20 million stock awards, 33 million stock options, and 15 million (weighted-average) share equivalents
related to convertible debt (acquired from RTI—see Note F) were not included in the computation of diluted EPS. Had
Alcoa generated net income in 2015, 77 million, 15 million, 12 million, and 3 million potential shares of common
stock related to the mandatory convertible preferred stock, convertible notes, stock awards, and stock options,
respectively, would have been included in diluted average shares outstanding.

In 2014, 16 million and 22 million share equivalents related to convertible notes and mandatory convertible preferred
stock, respectively, were not included in the computation of diluted EPS because their effect was anti-dilutive.

In 2013, basic average shares outstanding and diluted average shares outstanding were the same because the effect of
potential shares of common stock was anti-dilutive since Alcoa generated a net loss. As a result, 89 million share
equivalents related to convertible notes, 16 million stock awards, and 12 million stock options were not included in the
computation of diluted EPS. Had Alcoa generated sufficient income from continuing operations in 2013, 89 million,
9 million, and 2 million potential shares of common stock related to the convertible notes, stock awards, and stock
options, respectively, would have been included in diluted average shares outstanding.

Options to purchase 26 million, 3 million, and 12 million shares of common stock at a weighted average exercise price
of $12.75, $16.24, and $15.81 per share were outstanding as of December 31, 2015, 2014, and 2013, respectively, but
were not included in the computation of diluted EPS because they were anti-dilutive, as the exercise prices of the
options were greater than the average market price of Alcoa’s common stock.

The exercise of employee stock options generated a tax benefit of $3 and $9 in 2015 and 2014, respectively, and a tax
charge of $1 in 2013, representing only the difference between compensation expense recognized for financial
reporting and tax purposes. These amounts decreased equity and increased either current taxes payable or deferred tax
assets (not operating losses) in the respective periods.

145

Alcoa has unamortized tax-deductible goodwill of $27 resulting from intercompany stock sales and reorganizations.
Alcoa recognizes the tax benefits (at a 28% rate in 2015 and will be at a rate of 25% in 2016 and later years) associated
with this tax-deductible goodwill as it is being amortized for local income tax purposes rather than in the period in
which the transaction is consummated.

A reconciliation of the U.S. federal statutory rate to Alcoa’s effective tax rate was as follows (the effective tax rate for
2015 and 2014 was a provision on income and for 2013 was a provision on a loss):

In 2014, the noncontrolling interests’ impact on Alcoa’s effective tax rate was mostly due to the noncontrolling
interest’s share of a loss on the divestiture of an ownership interest in a mining and refining joint venture in
Jamaica (see Note F).
In November 2014, Spain enacted corporate tax reform that changed the corporate tax rate from 30% in 2014 to
28% in 2015 to 25% in 2016. As a result, Alcoa remeasured certain deferred tax assets related to Spanish
subsidiaries.
In 2014, a tax holiday for certain Alcoa subsidiaries in Brazil became effective (see below).

* Deferred tax assets with no expiration may still have annual limitations on utilization. Other represents deferred tax
assets whose expiration is dependent upon the reversal of the underlying temporary difference. A substantial amount
of Other relates to employee benefits that will become deductible for tax purposes over an extended period of time as
contributions are made to employee benefit plans and payments are made to retirees.

The total deferred tax asset (net of valuation allowance) is supported by projections of future taxable income exclusive
of reversing temporary differences (58%) and taxable temporary differences that reverse within the carryforward
period (42%).

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50%) that
a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential
sources of taxable income, including income available in carryback periods, future reversals of taxable temporary
differences, projections of taxable income, and income from tax planning strategies, as well as all available positive
and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of
future profitability within the carryforward period, including from tax planning strategies, and Alcoa’s experience with
similar operations. Existing favorable contracts and the ability to sell products into established markets are additional
positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or
carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing
projections of income. In certain jurisdictions, deferred tax assets related to cumulative losses exist without a valuation
allowance where in management’s judgment the weight of the positive evidence more than offsets the negative
evidence of the cumulative losses. Upon changes in facts and circumstances, management may conclude that deferred
tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a future charge to
establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive
and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the
appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also re-
measured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays.

In 2013, Alcoa recognized a $372 discrete income tax charge for valuation allowances on certain deferred tax assets in
Spain and the United States. Of this amount, a $237 valuation allowance was established on the full value of the
deferred tax assets related to a Spanish consolidated tax group. These deferred tax assets have an expiration period
ranging from 2016 (for certain credits) to an unlimited life (for operating losses). After weighing all available positive
and negative evidence, as described above, management determined that it was no longer more likely than not that
Alcoa will realize the tax benefit of these deferred tax assets. This was mainly driven by a decline in the outlook of the
Primary Metals business (2013 realized prices were the lowest since 2009) combined with prior year cumulative losses
of the Spanish consolidated tax group. During 2014, the underlying value of the deferred tax assets decreased due to a
remeasurement as a result of the enactment of new tax rates in Spain beginning in 2015, the sale of a member of the
Spanish consolidated tax group, and a change in foreign currency exchange rates. As a result the valuation allowance
decreased by the same amount. At December 31, 2015, the amount of the valuation allowance was $149. This valuation
allowance was reevaluated as of December 31, 2015, and no change to the allowance was deemed necessary based on
all available evidence. The need for this valuation allowance will be assessed on a continuous basis in future periods
and, as a result, a portion or all of the allowance may be reversed based on changes in facts and circumstances.

147

The remaining $135 recognized in 2013 relates to a valuation allowance established on a portion of available foreign
tax credits in the United States. These credits can be carried forward for 10 years, and have an expiration period
ranging from 2016 to 2023 as of December 31, 2013 (2016 to 2025 as of December 31, 2015). After weighing all
available positive and negative evidence, as described above, management determined that it was no longer more likely
than not that Alcoa will realize the full tax benefit of these foreign tax credits. This was primarily due to lower foreign
sourced taxable income after consideration of tax planning strategies and after the inclusion of earnings from foreign
subsidiaries projected to be distributable as taxable foreign dividends. This valuation allowance was reevaluated as of
December 31, 2015, and due to reductions in foreign sourced taxable income, a $134 discrete income tax charge was
recognized. Additionally, $15 of foreign tax credits expired at the end of 2015 resulting in a corresponding decrease to
the valuation allowance. At December 31, 2015, the amount of the valuation allowance was $254. The need for this
valuation allowance will be assessed on a continuous basis in future periods and, as a result, an increase or decrease to
this allowance may result based on changes in facts and circumstances.

In 2015, Alcoa recognized an additional $141 discrete income tax charge for valuation allowances on certain deferred
tax assets in Iceland and Suriname. Of this amount, an $85 valuation allowance was established on the full value of the
deferred tax assets in Suriname, which were related mostly to employee benefits and tax loss carryforwards. These
deferred tax assets have an expiration period ranging from 2016 to 2022. The remaining $56 charge relates to a
valuation allowance established on a portion of the deferred tax assets recorded in Iceland. These deferred tax assets
have an expiration period ranging from 2017 to 2023. After weighing all available positive and negative evidence, as
described above, management determined that it was no longer more likely than not that Alcoa will realize the tax
benefit of either of these deferred tax assets. This was mainly driven by a decline in the outlook of the Primary Metals
business, combined with prior year cumulative losses and a short expiration period. The need for this valuation
allowance will be assessed on a continuous basis in future periods and, as a result, a portion or all of the allowance may
be reversed based on changes in facts and circumstances.

In December 2011, one of Alcoa’s subsidiaries in Brazil applied for a tax holiday related to its expanded mining and
refining operations. During 2013, the application was amended and re-filed and, separately, a similar application was filed
for another one of the Company’s subsidiaries in Brazil. The deadline for the Brazilian government to deny the
application was July 11, 2014. Since Alcoa did not receive notice that its applications were denied, the tax holiday took
effect automatically on July 12, 2014. As a result, the tax rate applicable to qualified holiday income for these subsidiaries
decreased significantly (from 34% to 15.25%), resulting in future cash tax savings over the 10-year holiday period
(retroactively effective as of January 1, 2013). Additionally, a portion of one of the subsidiaries net deferred tax asset that
reverses within the holiday period was remeasured at the new tax rate (the net deferred tax asset of the other subsidiary
was not remeasured since it could still be utilized against the subsidiary’s future earnings not subject to the tax holiday).
This remeasurement resulted in a decrease to that subsidiary’s net deferred tax asset and a noncash charge to earnings of
$52 ($31 after noncontrolling interest).

The cumulative amount of Alcoa’s foreign undistributed net earnings for which no deferred taxes have been provided
was approximately $4,000 at December 31, 2015. Alcoa has a number of commitments and obligations related to the
Company’s growth strategy in foreign jurisdictions. As such, management has no plans to distribute such earnings in
the foreseeable future, and, therefore, has determined it is not practicable to determine the related deferred tax liability.

148

Alcoa and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign
jurisdictions. With a few minor exceptions, Alcoa is no longer subject to income tax examinations by tax authorities for
years prior to 2006. All U.S. tax years prior to 2015 have been audited by the Internal Revenue Service. Various state
and foreign jurisdiction tax authorities are in the process of examining Alcoa’s income tax returns for various tax years
through 2014.

For all periods presented, a portion of the balance at end of year pertains to state tax liabilities, which are presented
before any offset for federal tax benefits. The effect of unrecognized tax benefits, if recorded, that would impact the
annual effective tax rate for 2015, 2014, and 2013 would be approximately 12%, 4%, and (1)%, respectively, of pretax
book income (loss). Alcoa does not anticipate that changes in its unrecognized tax benefits will have a material impact
on the Statement of Consolidated Operations during 2016 (see Other Matters in Note N for a matter for which no
reserve has been recognized).

It is Alcoa’s policy to recognize interest and penalties related to income taxes as a component of the Provision for
income taxes on the accompanying Statement of Consolidated Operations. In 2015, 2014, and 2013, Alcoa recognized
$8, $1, and $2, respectively, in interest and penalties. Due to the expiration of the statute of limitations, settlements
with tax authorities, and refunded overpayments, Alcoa also recognized interest income of $2, $5, and $12 in 2015,
2014, and 2013, respectively. As of December 31, 2015 and 2014, the amount accrued for the payment of interest and
penalties was $9.

U. Receivables

Sale of Receivables Programs

Alcoa has an arrangement with three financial institutions to sell certain customer receivables without recourse on a
revolving basis. The sale of such receivables is completed through the use of a bankruptcy remote special purpose
entity, which is a consolidated subsidiary of Alcoa. This arrangement provides for minimum funding of $200 up to a
maximum of $500 for receivables sold. On March 30, 2012, Alcoa initially sold $304 of customer receivables in
exchange for $50 in cash and $254 of deferred purchase price under this arrangement. Alcoa has received additional
net cash funding of $200 for receivables sold ($1,258 in draws and $1,058 in repayments) since the program’s
inception (no draws or repayments occurred in 2015), including $40 ($710 in draws and $670 in repayments) in 2014.

As of December 31, 2015 and 2014, the deferred purchase price receivable was $249 and $356, respectively, which
was included in Other receivables on the accompanying Consolidated Balance Sheet. The deferred purchase price
receivable is reduced as collections of the underlying receivables occur; however, as this is a revolving program, the
sale of new receivables will result in an increase in the deferred purchase price receivable. The net change in the
deferred purchase price receivable was reflected in the Decrease (increase) in receivables line item on the
accompanying Statement of Consolidated Cash Flows. This activity is reflected as an operating cash flow because the
related customer receivables are the result of an operating activity with an insignificant, short-term interest rate risk.

149

In 2015 and 2014, the gross cash outflows and inflows associated with the deferred purchase price receivable were
$6,893 and $7,001, respectively, and $7,381 and $7,272, respectively. The gross amount of receivables sold and total
cash collected under this program since its inception was $24,598 and $24,099 respectively. Alcoa services the
customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded.

W. Pension and Other Postretirement Benefits

Alcoa maintains pension plans covering most U.S. employees and certain employees in foreign locations. Pension
benefits generally depend on length of service, job grade, and remuneration. Substantially all benefits are paid through
pension trusts that are sufficiently funded to ensure that all plans can pay benefits to retirees as they become due. Most
salaried and non-bargaining hourly U.S. employees hired after March 1, 2006 participate in a defined contribution plan
instead of a defined benefit plan.

On June 6, 2014, the United Steelworkers ratified a new five-year labor agreement covering approximately 6,100
employees at 10 U.S. locations; the previous labor agreement expired on May 15, 2014. In 2014, as a result of the
preparation for and ratification of the new agreement, Alcoa recognized $18 ($12 after-tax) in Cost of goods sold on
the accompanying Statement of Consolidated Operations for, among other items, business contingency costs and a one-
time signing bonus for employees. Additionally, as a result of the provisions of the new labor agreement, a significant
plan amendment was adopted by one of Alcoa’s U.S. pension plans. Accordingly, this plan was required to be
remeasured, and through this process, the discount rate was updated from 4.80% at December 31, 2013 to 4.25% at
May 31, 2014. The plan remeasurement resulted in an increase to both Alcoa’s pension liability of $100 and a
combination of the plan’s unrecognized net actuarial loss and prior service cost (included in Accumulated other
comprehensive loss) of $65 (after-tax). The plan remeasurement also resulted in a $13 decrease to 2014 net periodic
benefit cost.

Alcoa also maintains health care and life insurance postretirement benefit plans covering eligible U.S. retired
employees and certain retirees from foreign locations. Generally, the medical plans are unfunded and pay a percentage
of medical expenses, reduced by deductibles and other coverage. Life benefits are generally provided by insurance
contracts. Alcoa retains the right, subject to existing agreements, to change or eliminate these benefits. All salaried and
certain non-bargaining hourly U.S. employees hired after January 1, 2002 and certain bargaining hourly U.S.
employees hired after July 1, 2010 are not eligible for postretirement health care benefits. All salaried and certain
hourly U.S. employees that retire on or after April 1, 2008 are not eligible for postretirement life insurance benefits.

150

Effective January 1, 2015, Alcoa no longer offers postretirement health care benefits to Medicare-eligible, primarily
non-bargaining, U.S. retirees through Company-sponsored plans. Qualifying retirees (hired prior to January 1, 2002),
both current and future, may access these benefits in the marketplace by purchasing coverage directly from insurance
carriers. This change resulted in the adoption of a significant plan amendment by certain Alcoa U.S. postretirement
benefit plans in August 2014. Accordingly, these plans were required to be remeasured, and through this process, the
discount rate was updated from 4.80% at December 31, 2013 to 4.15% at August 31, 2014. The remeasurement of the
plans resulted in a decrease to both Alcoa’s other postretirement benefits liability of $90 and a combination of the
plans’ unrecognized net actuarial loss and prior service benefit (included in Accumulated other comprehensive loss) of
$59 (after-tax). The remeasurement of the plans also resulted in a $7 decrease to 2014 net periodic benefit cost.

In 2015, 2014, and 2013, net periodic benefit cost for U.S pension plans was $423, $335, and $391, respectively.
In 2015, 2014, and 2013, net periodic benefit cost for other postretirement benefits reflects a reduction of $34, $38, and
$55, respectively, related to the recognition of the federal subsidy awarded under Medicare Part D.
In 2015, settlements were due to workforce reductions (see Note D) and the payment of lump sum benefits and/or
purchases of annuity contracts. In 2014, settlements were due to workforce reductions (see Note D). In 2013, settlements
were due to the payment of lump sum benefits and/or purchases of annuity contracts.
In 2015 and 2013, curtailments were due to elimination of benefits or workforce reductions (see Note D).
In 2015 and 2013, special termination benefits were due to workforce reductions (see Note D).

Assumptions

Weighted average assumptions used to determine benefit obligations for U.S. pension and other postretirement benefit
plans were as follows (assumptions for non-U.S plans did not differ materially):

December 31,

Discount rate
Rate of compensation increase

2015

2014

4.29% 4.00%
3.5

3.5

The discount rate is determined using a Company-specific yield curve model (above-median) developed with the
assistance of an external actuary. The cash flows of the plans’ projected benefit obligations are discounted using a
single equivalent rate derived from yields on high quality corporate bonds, which represent a broad diversification of
issuers in various sectors, including finance and banking, consumer products, transportation, insurance, and
pharmaceutical, among others. The yield curve model parallels the plans’ projected cash flows, which have an average
duration of 10 years, and the underlying cash flows of the bonds included in the model exceed the cash flows needed to
satisfy the Company’s plans’ obligations multiple times.

The rate of compensation increase is based upon actual experience. For 2016, the rate of compensation increase will be
3.5%, which approximates the five-year average.

Weighted average assumptions used to determine net periodic benefit cost for U.S. pension and other postretirement
benefit plans were as follows (assumptions for non-U.S plans did not differ materially):

Discount rate*
Expected long-term rate of return on plan assets
Rate of compensation increase

2015

2014

2013

4.00% 4.80% 4.15%
8.00
7.75
3.50
3.50

8.50
3.50

* In all periods presented, the respective discount rates were used to determine net periodic benefit cost for most U.S.
pension plans for the full annual period. However, the discount rates for a limited number of plans were updated
during 2015, 2014, and 2013 to reflect the remeasurement of these plans due to new union labor agreements,
settlements, and/or curtailments. The updated discount rates used were not significantly different from the discount
rates presented.

In conjunction with the annual measurement of the funded status of Alcoa’s pension and other postretirement benefit
plans at December 31, 2015, management elected to change the manner in which the interest cost component of net
periodic benefit cost will be determined in 2016 and beyond. Previously, the interest cost component was determined
by multiplying the single equivalent rate described above and the aggregate discounted cash flows of the plans’
projected benefit obligations. Under the new methodology, the interest cost component will be determined by
aggregating the product of the discounted cash flows of the plans’ projected benefit obligations for each year and an
individual spot rate (referred to as the “spot rate” approach). This change will result in a lower interest cost component
of net periodic benefit cost under the new methodology compared to the previous methodology of approximately $100
($65 after-tax) in 2016. Management believes this new methodology, which represents a change in an accounting
estimate, is a better measure of the interest cost as each year’s cash flows are specifically linked to the interest rates of
bond payments in the same respective year.

The expected long-term rate of return on plan assets is generally applied to a five-year market-related value of plan
assets (a four-year average or the fair value at the plan measurement date is used for certain non-U.S. plans). The
process used by management to develop this assumption is one that relies on a combination of historical asset return
information and forward-looking returns by asset class. As it relates to historical asset return information, management
focuses on the annual, 10-year moving, and 20-year moving averages when developing this assumption. Management
also incorporates expected future returns on current and planned asset allocations using information from various
external investment managers and consultants, as well as management’s own judgment.

154

For 2015, 2014, and 2013, the expected long-term rate of return used by management was based on the prevailing and
planned strategic asset allocations, as well as estimates of future returns by asset class. These rates fell within the
respective range of the 20-year moving average of actual performance and the expected future return developed by
asset class. In 2015, the decrease of 25 basis points in the expected long-term rate of return was due to a decrease in the
20-year moving average of actual performance. For 2016, management anticipates that 7.75% will be the expected
long-term rate of return.

Assumed health care cost trend rates for U.S. other postretirement benefit plans were as follows (assumptions for non-
U.S plans did not differ materially):

Health care cost trend rate assumed for next year
Rate to which the cost trend rate gradually declines
Year that the rate reaches the rate at which it is assumed to remain

2015

2014

2013

5.5% 5.5% 5.5%
4.5% 4.5% 4.5%

2019

2018

2017

The assumed health care cost trend rate is used to measure the expected cost of gross eligible charges covered by
Alcoa’s other postretirement benefit plans. For 2016, a 5.5% trend rate will be used, reflecting management’s best
estimate of the change in future health care costs covered by the plans. The plans’ actual annual health care cost trend
experience over the past three years has ranged from 4.0%. to 9.6% Management does not believe this three-year range
is indicative of expected increases for future health care costs over the long-term.

Assumed health care cost trend rates have an effect on the amounts reported for the health care plan. A one-percentage
point change in these assumed rates would have the following effects:

Effect on total of service and interest cost components

The principal objectives underlying the investment of the pension plans’ assets are to ensure that Alcoa can properly
fund benefit obligations as they become due under a broad range of potential economic and financial scenarios,
maximize the long-term investment return with an acceptable level of risk based on such obligations, and broadly
diversify investments across and within various asset classes to protect asset values against adverse movements.
Specific objectives for long-term investment strategy include reducing the volatility of pension assets relative to
pension liabilities and achieving risk factor diversification across the balance of the asset portfolio. A portion of the
assets are matched to the interest rate profile of the benefit obligation through long duration fixed income investments
and exposure to broad equity risk has been decreased and diversified through investments in discretionary and

155

systematic macro hedge funds, long/short equity hedge funds, and global and emerging market equities. Investments
are further diversified by strategy, asset class, geography, and sector to enhance returns and mitigate downside risk. A
large number of external investment managers are used to gain broad exposure to the financial markets and to mitigate
manager-concentration risk.

Investment practices comply with the requirements of the Employee Retirement Income Security Act of 1974 (ERISA)
and other applicable laws and regulations. The use of derivative instruments is permitted where appropriate and
necessary for achieving overall investment policy objectives. Currently, the use of derivative instruments is not
significant when compared to the overall investment portfolio.

The following section describes the valuation methodologies used by the trustees to measure the fair value of pension
plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally
classified (see Note X for the definition of fair value and a description of the fair value hierarchy).

Equities. These securities consist of: (i) direct investments in the stock of publicly traded U.S. and non-U.S. companies
and are valued based on the closing price reported in an active market on which the individual securities are traded
(generally classified in Level 1); (ii) the plans’ share of commingled funds that are invested in the stock of publicly
traded companies and are valued at the net asset value of shares held at December 31 (included in Level 1 if quoted in
an active market, otherwise these investments are included in Level 2); and (iii) direct investments in long/short equity
hedge funds and private equity (limited partnerships and venture capital partnerships) and are valued by investment
managers based on the most recent financial information available, which typically represents significant unobservable
data (generally classified as Level 3).

Fixed income. These securities consist of: (i) U.S. government debt and are generally valued using quoted prices
(included in Level 1); (ii) publicly traded U.S. and non-U.S. fixed interest obligations (principally corporate bonds and
debentures) and are valued through consultation and evaluation with brokers in the institutional market using quoted
prices and other observable market data (included in Level 2); (iii) cash and cash equivalents, which consist of
government securities in commingled funds, and are generally valued using observable market data (included in Level
2); and (iv) commercial and residential mortgage-backed securities and are valued by investment managers based on
the most recent financial information available, which typically represents significant unobservable data (generally
classified as Level 3).

Other investments. These investments include, among others: (i) exchange traded funds, such as gold, and real estate
investment trusts and are valued based on the closing price reported in an active market on which the investments are
traded (included in Level 1); (ii) the plans’ share of commingled funds that are invested in real estate investment trusts
and are valued at the net asset value of shares held at December 31 (generally included in Level 3, however, if fair
value is able to be determined through the use of quoted market prices of similar assets or other observable market
data, then the investments are classified in Level 2); and (iii) direct investments of discretionary and systematic macro
hedge funds and private real estate (includes limited partnerships) and are valued by investment managers based on the
most recent financial information available, which typically represents significant unobservable data (generally
classified as Level 3, however, if fair value is able to be determined through the use of quoted market prices of similar
assets or other observable market data, then the investments are classified in Level 2).

The fair value methods described above may not be indicative of net realizable value or reflective of future fair values.
Additionally, while Alcoa believes the valuation methods used by the plans’ trustees are appropriate and consistent
with other market participants, the use of different methodologies or assumptions to determine the fair value of certain
financial instruments could result in a different fair value measurement at the reporting date.

Funding and Cash Flows

It is Alcoa’s policy to fund amounts for pension plans sufficient to meet the minimum requirements set forth in
applicable country benefits laws and tax laws, including the Pension Protection Act of 2006; the Worker, Retiree, and
Employer Recovery Act of 2008; the Moving Ahead for Progress in the 21st Century Act of 2012; the Highway and
Transportation Funding Act of 2014; and the Bipartisan Budget Act of 2015 for U.S. plans. From time to time, Alcoa
contributes additional amounts as deemed appropriate. In 2015 and 2014, cash contributions to Alcoa’s pension plans
were $470 and $501. The minimum required contribution to pension plans in 2016 is estimated to be $300, of which
$218 is for U.S. plans.

Benefit payments expected to be paid to pension and other postretirement benefit plans’ participants and expected
Medicare Part D subsidy receipts are as follows:

Alcoa sponsors savings and investment plans in several countries, including the United States and Australia. Expenses
related to these plans were $142 in 2015, $151 in 2014, and $149 in 2013. In the United States, employees may
contribute a portion of their compensation to the plans, and Alcoa matches a portion of these contributions in
equivalent form of the investments elected by the employee. Prior to January 1, 2014, Alcoa’s match was mostly in
company stock.

X. Derivatives and Other Financial Instruments

Fair Value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an
orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes
between (i) market participant assumptions developed based on market data obtained from independent sources
(observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the
best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad
levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities
(Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are
described below:

• Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for

identical, unrestricted assets or liabilities.

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability,
either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted
prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted
prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally
from or corroborated by observable market data by correlation or other means.

• Level 3—Inputs that are both significant to the fair value measurement and unobservable.

Derivatives. Alcoa is exposed to certain risks relating to its ongoing business operations, including financial, market,
political, and economic risks. The following discussion provides information regarding Alcoa’s exposure to the risks of
changing commodity prices, interest rates, and foreign currency exchange rates.

Alcoa’s commodity and derivative activities are subject to the management, direction, and control of the Strategic Risk
Management Committee (SRMC), which is composed of the chief executive officer, the chief financial officer, and
other officers and employees that the chief executive officer selects. The SRMC meets on a periodic basis to review
derivative positions and strategy and reports to Alcoa’s Board of Directors on the scope of its activities.

The aluminum, energy, interest rate, and foreign exchange contracts are held for purposes other than trading. They are
used primarily to mitigate uncertainty and volatility, and to cover underlying exposures. Alcoa is not involved in
trading activities for energy, weather derivatives, or other nonexchange commodity trading activities.

A number of Alcoa’s aluminum, energy, and foreign exchange contracts are classified as Level 1 and an interest rate
contract is classified as Level 2 under the fair value hierarchy. These energy, foreign exchange, and interest rate
contracts are not material to Alcoa’s Consolidated Financial Statements for all periods presented except as follows for
two foreign exchange contracts. Alcoa had a forward contract to purchase $53 (C$58) to mitigate the foreign currency
risk related to a Canadian-denominated loan, which was repaid on August 31, 2014 upon maturity. The forward
contract expired on August 5, 2014 and a gain of $1 was recognized in Other expenses, net on the accompanying
Statement of Consolidated Operations in 2014. Also, Alcoa had a forward contract to purchase $231 (R$543) to
mitigate the foreign currency risk associated with a potential future transaction denominated in Brazilian reais. This
contract expired on March 31, 2014 and a loss of $4 was recognized in Other expenses, net on the accompanying
Statement of Consolidated Operations in 2014.

For the aluminum contracts classified as Level 1, the total fair value of derivatives recorded as assets and liabilities was
$8 and $58 and $2 and $31 at December 31, 2015 and 2014, respectively. These contracts were entered into to either
hedge forecasted sales or purchases of aluminum in order to manage the associated aluminum price risk. Certain of
these contracts are designated as hedging instruments, either fair value or cash flow, and the remaining are not
designated as such. Combined, Alcoa recognized a net gain of $19, a net loss of $15, and a net gain of $4 in Sales on
the accompanying Statement of Consolidated Operations in 2015, 2014, and 2013, respectively, related to these
aluminum contracts. Additionally, for the contracts designated as cash flow hedges, Alcoa recognized an unrealized
gain of $9 in Other comprehensive loss in 2013.

159

In addition to the Level 1 and 2 derivative instruments described above, Alcoa has nine derivative instruments
classified as Level 3 under the fair value hierarchy. These instruments are composed of seven embedded aluminum
derivatives, an energy contract, and an embedded credit derivative, all of which relate to energy supply contracts
associated with eight smelters and three refineries. Five of the embedded aluminum derivatives and the energy contract
were designated as cash flow hedging instruments and two of the embedded aluminum derivatives and the embedded
credit derivative were not designated as hedging instruments.

The following section describes the valuation methodologies used by Alcoa to measure its Level 3 derivative
instruments at fair value. Derivative instruments classified as Level 3 in the fair value hierarchy represent those in
which management has used at least one significant unobservable input in the valuation model. Alcoa uses a
discounted cash flow model to fair value all Level 3 derivative instruments. Where appropriate, the description below
includes the key inputs to those models and any significant assumptions. These valuation models are reviewed and
tested at least on an annual basis.

Inputs in the valuation models for Level 3 derivative instruments are composed of the following: (i) quoted market
prices (e.g., aluminum prices on the 10-year London Metal Exchange (LME) forward curve and energy prices),
(ii) significant other observable inputs (e.g., information concerning time premiums and volatilities for certain option
type embedded derivatives and regional premiums for aluminum contracts), and (iii) unobservable inputs (e.g.,
aluminum and energy prices beyond those quoted in the market). For periods beyond the term of quoted market prices
for aluminum, Alcoa estimates the price of aluminum by extrapolating the 10-year LME forward curve. Additionally,
for periods beyond the term of quoted market prices for energy, management has developed a forward curve based on
independent consultant market research. Where appropriate, valuations are adjusted for various factors such as
liquidity, bid/offer spreads, and credit considerations. Such adjustments are generally based on available market
evidence (Level 2). In the absence of such evidence, management’s best estimate is used (Level 3). If a significant
input that is unobservable in one period becomes observable in a subsequent period, the related asset or liability would
be transferred to the appropriate classification (Level 1 or 2) in the period of such change (there were no such transfers
in the periods presented).

Alcoa has embedded derivatives in two power contracts that index the price of power to the LME price of aluminum.
Additionally, in late 2014, Alcoa renewed three power contracts, each of which contain an embedded derivative that
indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivatives in
these five power contracts are primarily valued using observable market prices; however, due to the length of the
contracts, the valuation models also require management to estimate the long-term price of aluminum based upon an
extrapolation of the 10-year LME forward curve and/or 5-year Midwest premium curve. Significant increases or
decreases in the actual LME price beyond 10 years and/or the Midwest premium beyond 5 years would result in a
higher or lower fair value measurement. An increase in actual LME price and/or the Midwest premium over the inputs
used in the valuation models will result in a higher cost of power and a corresponding decrease to the derivative asset
or increase to the derivative liability. The embedded derivatives have been designated as cash flow hedges of forward
sales of aluminum. Unrealized gains and losses were included in Other comprehensive loss on the accompanying
Consolidated Balance Sheet while realized gains and losses were included in Sales on the accompanying Statement of
Consolidated Operations.

Also, Alcoa has a power contract separate from above that contains an LME-linked embedded derivative. The
embedded derivative is valued using the probability and interrelationship of future LME prices, Australian dollar to
U.S. dollar exchange rates, and the U.S. consumer price index. Significant increases or decreases in the LME price
would result in a higher or lower fair value measurement. An increase in actual LME price over the inputs used in the
valuation model will result in a higher cost of power and a corresponding decrease to the derivative asset. This
embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded
derivative were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations
while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated
Operations as electricity purchases were made under the contract. At the time this derivative asset was recognized, an
equivalent amount was recognized as a deferred credit in Other noncurrent liabilities and deferred credits on the

160

accompanying Consolidated Balance Sheet (see Note L). This deferred credit is recognized in Other expenses
(income), net on the accompanying Statement of Consolidated Operations as power is received over the life of the
contract. Alcoa had a similar power contract and related embedded derivative associated with another smelter and
rolling mill combined; however, the contract and related derivative instrument matured in July 2014.

Additionally, Alcoa has a natural gas supply contract, which has an LME-linked ceiling. This embedded derivative is
valued using probabilities of future LME aluminum prices and the price of Brent crude oil (priced on Platts), including
the interrelationships between the two commodities subject to the ceiling. Any change in the interrelationship would
result in a higher or lower fair value measurement. An LME ceiling was embedded into the contract price to protect
against an increase in the price of oil without a corresponding increase in the price of LME. An increase in oil prices
with no similar increase in the LME price would limit the increase of the price paid for natural gas. This embedded
derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative
were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations while
realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated
Operations as gas purchases were made under the contract.

Furthermore, Alcoa has an embedded derivative in a power contract that indexes the difference between the long-term
debt ratings of Alcoa and the counterparty from any of the three major credit rating agencies. Management uses market
prices, historical relationships, and forecast services to determine fair value. Significant increases or decreases in any
of these inputs would result in a lower or higher fair value measurement. A wider credit spread between Alcoa and the
counterparty would result in a higher cost of power and a corresponding increase in the derivative liability. This
embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses were included in
Other expenses (income), net on the accompanying Statement of Consolidated Operations while realized gains and
losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity
purchases were made under the contract.

Finally, Alcoa has a derivative contract that will hedge the anticipated power requirements at one of its smelters once
the existing power contract expires in September 2016. Beyond the term where market information is available,
management has developed a forward curve, for valuation purposes, based on independent consultant market research.
Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Lower
prices in the power market would cause a decrease in the derivative asset. The derivative contract has been designated
as a cash flow hedge of future purchases of electricity. Unrealized gains and losses on this contract were recorded in
Other comprehensive loss on the accompanying Consolidated Balance Sheet. Once the designated hedge period begins
in September 2016, realized gains and losses will be recorded in Cost of goods sold as electricity purchases are made
under the power contract. Alcoa had a similar contract related to another smelter once the prior existing contract
expired in 2014, but elected to terminate the new contract in early 2013. This election was available to Alcoa under the
terms of the contract and was made due to a projection that suggested the contract would be uneconomical. Prior to
termination, the new contract was accounted for in the same manner.

* The fair value of the energy contract reflected as a liability in this table is lower by $2 compared to the respective
amount reflected in the Level 3 tables presented below. This is due to the fact that this contract is in a liability
position for the current portion but is in an asset position for the noncurrent portion, and is reflected as such on the
accompanying Consolidated Balance Sheet. However, this derivative is reflected as a net liability in the above table
for purposes of presenting the assumptions utilized to measure the fair value of the derivative instrument in its

Derivatives Designated As Hedging Instruments—Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of unrealized gains
or losses on the derivative is reported as a component of other comprehensive income (OCI). Realized gains or losses
on the derivative are reclassified from OCI into earnings in the same period or periods during which the hedged
transaction impacts earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge
components excluded from the assessment of effectiveness are recognized directly in earnings immediately.

Alcoa has five Level 3 embedded aluminum derivatives and one Level 3 energy contract (a second one was terminated
in early 2013) that have been designated as cash flow hedges as follows.

Embedded aluminum derivatives. Alcoa has entered into energy supply contracts that contain pricing provisions
related to the LME aluminum price. The LME-linked pricing features are considered embedded derivatives. Five of
these embedded derivatives have been designated as cash flow hedges of forward sales of aluminum, three of which
were new derivatives contained in three power contracts that were renewed in late 2014. At December 31, 2015 and
2014, these embedded aluminum derivatives hedge forecasted aluminum sales of 3,307 kmt and 3,610 kmt,
respectively.

In 2015, 2014, and 2013, Alcoa recognized an unrealized gain of $1,155, $78, and $190, respectively, in Other
comprehensive loss related to these five derivative instruments. Additionally, Alcoa reclassified a realized loss of $21,
$28, and $29 from Accumulated other comprehensive loss to Sales in 2015, 2014, and 2013, respectively. There was
no ineffectiveness related to these five derivative instruments in 2015, 2014, and 2013. Assuming market rates remain
constant with the rates at December 31, 2015, a realized gain of $45 is expected to be recognized in Sales over the next
12 months.

Energy contract. Alcoa has a derivative contract that will hedge the anticipated power requirements at one of its
smelters once the existing power contract expires in 2016. Alcoa had a similar contract related to another smelter once
the prior existing contract expired in 2014, but elected to terminate the new contract in early 2013 (see additional
information in description of Level 3 derivative contracts above). At December 31, 2015 and 2014, this energy contract
hedges forecasted electricity purchases of 59,409,328 megawatt hours. In 2015, 2014, and 2013, Alcoa recognized an
unrealized loss of $2, an unrealized loss of $4, and an unrealized gain of $3, respectively, in Other comprehensive loss.
Additionally, Alcoa recognized a loss of $3 in Other expenses, net related to hedge ineffectiveness in 2015. There was
no ineffectiveness related to the respective energy contracts outstanding in 2014 and 2013.

Derivatives Not Designated As Hedging Instruments

Alcoa has two Level 3 embedded aluminum derivatives and one Level 3 embedded credit derivative that do not qualify
for hedge accounting treatment. As such, gains and losses related to the changes in fair value of these instruments are
recorded directly in earnings. In 2015, 2014, and 2013, Alcoa recognized a loss of $25, a loss of $13, and a gain of $36,
respectively, in Other expenses (income), net, of which a loss of $8, a loss of $15, and a gain of $28, respectively,
related to the two embedded aluminum derivatives and a loss of $17, a gain of $2, and a gain of $8, respectively,
related to the embedded credit derivative.

Material Limitations

The disclosures with respect to commodity prices, interest rates, and foreign currency exchange risk do not take into
account the underlying commitments or anticipated transactions. If the underlying items were included in the analysis,
the gains or losses on the futures contracts may be offset. Actual results will be determined by a number of factors that
are not under Alcoa’s control and could vary significantly from those factors disclosed.

165

Alcoa is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as
credit or performance risk with respect to its hedged customers’ commitments. Although nonperformance is possible,
Alcoa does not anticipate nonperformance by any of these parties. Contracts are with creditworthy counterparties and
are further supported by cash, treasury bills, or irrevocable letters of credit issued by carefully chosen banks. In
addition, various master netting arrangements are in place with counterparties to facilitate settlement of gains and
losses on these contracts.

The following methods were used to estimate the fair values of other financial instruments:

Cash and cash equivalents, Restricted cash, Short-term borrowings, and Commercial paper. The carrying
amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and
cash equivalents, Restricted cash, and Commercial paper were classified in Level 1, and Short-term borrowings were
classified in Level 2.

Noncurrent receivables. The fair value of noncurrent receivables was based on anticipated cash flows, which
approximates carrying value, and was classified in Level 2 of the fair value hierarchy.

Available-for-sale securities. The fair value of such securities was based on quoted market prices. These financial
instruments consist of exchange-traded fixed income and equity securities, which are carried at fair value and were
classified in Level 1 of the fair value hierarchy.

Contingent payment related to an acquisition (see Note F). The fair value was based on the net present value of
expected future cash flows and was classified in Level 3 of the fair value hierarchy.

Long-term debt due within one year and Long-term debt, less amount due within one year. The fair value was
based on quoted market prices for public debt and on interest rates that are currently available to Alcoa for issuance of
debt with similar terms and maturities for non-public debt. The fair value amounts for all Long-term debt were
classified in Level 2 of the fair value hierarchy.

Y. Proposed Separation Transaction

On September 28, 2015, Alcoa announced that its Board of Directors approved a plan to separate into two independent,
publicly-traded companies. One company will comprise the Alumina and Primary Metals segments and the other
company will comprise the Global Rolled Products, Engineered Products and Solutions, and Transportation and
Construction Solutions segments. Alcoa is targeting to complete the separation in the second half of 2016. The
transaction is subject to a number of conditions, including, but not limited to, final approval by Alcoa’s Board of
Directors, receipt of a favorable opinion of legal counsel with respect to the tax-free nature of the transaction for U.S.
federal income tax purposes, and the effectiveness of a Form 10 registration statement to be filed with the U.S.
Securities and Exchange Commission. Upon completion of the separation, Alcoa shareholders will own all of the
outstanding shares of both companies. Alcoa may, at any time and for any reason until the proposed transaction is
complete, abandon the separation plan or modify or change its terms. In 2015, Alcoa recognized $24 (pre- and after-
tax) in Selling, general administrative, and other expenses on the accompanying Statement of Consolidated Operations
for costs related to the proposed separation transaction.

Z. Subsequent Events

Management evaluated all activity of Alcoa and concluded that no subsequent events have occurred that would require
recognition in the Consolidated Financial Statements or disclosure in the Notes to the Consolidated Financial
Statements, except as described below.

On January 26, 2016, the European Court of Justice issued a decision in connection with legal proceedings related to
whether the extension of energy tariffs by Italy to Alcoa constituted unlawful state aid (see European Commission
Matters in Note N). In addition, a separate but related matter was also updated as a result of the aforementioned
decision (see Other Matters in the Litigation section of Note N).

(1) Reflects the cumulative effect of the accounting change for conditional asset retirement obligations in 2005.
(2)

Primary aluminum product shipments are not synonymous with aluminum shipments of the Primary Metals segment, as a
portion of this segment’s aluminum shipments relate to fabricated products.

(3) Nameplate capacity or production is equivalent to the sum of Consolidated capacity or production, the joint venture partner’s

(4)

share of capacity or production from certain smelters majority-owned by Alcoa, and Alcoa’s share of capacity or production of
50-percent or less owned smelters.
In 2015, Alcoa adopted changes issued by the Financial Accounting Standards Board to the balance sheet classification of
deferred income taxes (see Recently Adopted Accounting Guidance in Note A to the Consolidated Financial Statements in
Part II Item 8 of Alcoa’s 2015 Form 10-K). For comparative purposes, management elected to retrospectively apply these
changes to years 2011 through 2014 (consistent with the periods presented in Selected Financial Data in Part II Item 6 of
Alcoa’s 2015 Form 10-K). As a result, Total assets for 2011 through 2014 were updated to reflect these changes; however, as a
practical matter, Total assets prior to 2011 were not updated to reflect these changes.

Net income attributable to Alcoa – as adjusted
Net income attributable to Alcoa – as adjusted is a non-GAAP financial measure. Management believes that this measure is
meaningful to investors because management reviews the operating results of Alcoa excluding the impacts of restructuring and
other charges, discrete tax items, and other special items (collectively, “special items”). There can be no assurances that additional
special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to
consider both Net (loss) income attributable to Alcoa determined under GAAP as well as Net income attributable to Alcoa – as
adjusted.

Reconciliation of Free Cash Flow

Cash from operations
Capital expenditures
Free cash flow
Free Cash Flow is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because
management reviews cash flows generated from operations after taking into consideration capital expenditures due to the fact that
these expenditures are considered necessary to maintain and expand Alcoa’s asset base and are expected to generate future cash
flows from operations. It is important to note that Free Cash Flow does not represent the residual cash flow available for
discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not
deducted from the measure.

(1) The deferred purchase price receivable relates to an arrangement to sell certain customer receivables to several financial

institutions on a recurring basis. Alcoa is adding back this receivable for the purposes of the Days Working Capital calculation.

(2) The Working Capital for each period presented represents an average quarter Working Capital, which reflects the capital tied
up during a given quarter. As such, the components of Working Capital for each period presented represent the average of the
ending balances in each of the three months during the respective quarter.

Reconciliation of Adjusted EBITDA

Net (loss) income attributable to Alcoa
Add:

Net income (loss) attributable to noncontrolling interests
Provision for income taxes
Other expenses, net
Interest expense
Restructuring and other charges
Impairment of goodwill
Provision for depreciation, depletion, and amortization

Adjusted EBITDA
Total debt
Debt-to-Adjusted EBITDA ratio
Alcoa’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-
back for depreciation, depletion, and amortization. Net margin is equivalent to Sales minus the following items: Cost of goods
sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation,
depletion, and amortization. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is
meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa’s operating performance
and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly
titled measures of other companies.

Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the Global Rolled Products and
Engineered Products and Solutions (now Engineered Products and Solutions and Transportation and Construction Solutions – see below) segments in
order to enhance the visibility of the underlying operating performance of these businesses. Metal price lag describes the timing difference created when
the average price of metal sold differs from the average cost of the metal when purchased by the respective segment. The impact of metal price lag is now
reported as a separate line item in Alcoa’s reconciliation of total segment ATOI to consolidated net (loss) income attributable to Alcoa. As a result, this
change does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change.

In the third quarter of 2015, management approved a realignment of Alcoa’s Engineered Products and Solutions segment due to the expansion of this part
of Alcoa’s business portfolio through both organic and inorganic growth. This realignment consisted of moving both the Alcoa Wheel and Transportation
Products and Building and Construction Systems business units to a new reportable segment named Transportation and Construction Solutions.
Additionally, the Latin American soft alloy extrusions business previously included in Corporate was moved into the new Transportation and
Construction Solutions segment. The remaining Engineered Products and Solutions segment consists of the Alcoa Fastening Systems and Rings (renamed
to include portions of the Firth Rixson business acquired in November 2014), Alcoa Power and Propulsion (includes the TITAL business acquired in
March 2015), Alcoa Forgings and Extrusions (includes the other portions of Firth Rixson), and Alcoa Titanium and Engineered Products (a new business
unit that consists solely of the RTI International Metals business acquired in July 2015) business units. Segment information for all prior periods
presented was updated to reflect the new segment structure.
