FORWARD LOOKING STATEMENTS

This Annual Report
contains certain forward-looking statements, including statements regarding (i) certain plans, strategies and objectives of management, (ii) scheduled closure of certain operations or facilities, (iii) anticipated production or
construction commencement dates, (iv) expected costs of construction of projects or products or level of production output, (v) the anticipated productive lives of projects and mines and (vi) estimates of expected dividends to be
received from AWAC. Forward-looking statements include those containing such words as anticipate, estimates, should, will, expects, plans or similar expressions. Such
forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors, many of which are beyond the control of Alumina Limited, which may cause actual results to differ materially
from those expressed in the statements contained in this Annual Report.

For example, the amount of any future dividends
received from AWAC will be dependent in part on the future revenues from AWACs operations, described in this Annual Report which in turn are based in part on the market price of the products and metals produced, which may vary significantly
from current levels. Virtually all of our income is derived from our share of the earnings generated by AWAC. Such variations, if materially adverse, may impact the extent of the dividends from AWAC paid to us as well as the timing or feasibility of
the development of a particular project or the expansion of certain facilities. Other factors that may affect actual construction or production commencement dates, costs or production output and anticipated lives of operations or facilities of AWAC
include the ability of AWAC to profitably produce and transport its products or metals to applicable markets, the impact of foreign currency exchange rates on the market prices of the products or metals produced and activities of governmental
authorities in certain countries where such facilities are being operated including increases in taxes, changes in environmental and other regulations, and political uncertainty. Alumina Limited can give no assurances that the actual production or
commencement dates, cost or production output, revenue, or anticipated lives of the facilities discussed herein will not differ materially from the statements contained in this Annual Report. Alumina Limited undertakes no obligation to publicly
update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.

Exchange Rates

Alumina Limited published its Consolidated Financial Statements in Australian dollars until December 2009. With the commissioning of
production at the Juruti mine and the Alumar refinery in Brazil completed, Alumina Limited reached the end of the investment program in Brazil. Greater production and cash flows to shareholders was expected from those assets in the future. Most
dividends are also received in US dollars. The Board recognised that this changed the balance of factors that are assessed to determine Alumina Limiteds functional currency and determined that Alumina Limiteds functional currency would
be changed to US dollars effective for the reporting period December 31, 2010.

Following the change in functional
currency, Alumina Limited elected to change its presentation currency from Australian dollars to US dollars from January 1, 2010. The change in presentation currency represents a voluntary change in accounting policy, which has been applied
retrospectively.

To give effect to the change in functional and presentation currency, the assets, liabilities, contributed
equity, reserves and retained earnings of entities with an Australian dollar functional currency as at December 31, 2009, were converted to US dollars at period end exchange rates of AUD/USD 0.8972, and AUD/USD 0.6928 as at December 31,
2008. Revenue and expenses were converted at an average rate of AUD/USD 0.7123 for the six months ending June 30, 2009 and AUD/USD 0.8711 for the six months ending December 31, 2009 and AUD/USD 0.8519 for the 12 months ending
December 31, 2008.

D. Risk Factors

Alumina Limiteds business, financial condition or results of operations may be impacted by a number of factors. In addition to the
factors discussed separately in this report, the following are the most significant factors that could cause AWACs or Alumina Limiteds actual results to differ materially from those projected in any forward-looking statements:

The aluminium industry generally remains highly cyclical and is influenced by a number of factors including global
economic conditions.

The aluminium industry generally is highly cyclical. AWAC is subject to cyclical fluctuations in
global economic conditions and aluminium end-use markets. Demand for AWACs products is sensitive to these fluctuations. Alumina Limited is unable to predict the future course of industry variables or the strength, pace or sustainability of the
economic recovery and the effects of government intervention. Another major economic downturn, a prolonged recovery period, or disruptions in the financial markets could have a material adverse effect on AWACs and Alumina Limiteds
business or financial condition or results of operations.

Market-driven balancing of global aluminium 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 aluminium, aluminium producers have varied portions of their aluminium production. However, the existence of non-market forces on global aluminium industry capacity, such as political pressures in certain
countries to keep jobs or to maintain or further develop industry self-sufficiency, may 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 aluminium, this may result in a weak pricing environment and margin compression for aluminium producers, including AWAC. Any such cuts in aluminium production are likely to impact on demand for and production of alumina and this is likely
to adversely affect AWAC, such as in reduced sales volumes or lower price received. In addition, there are significant volumes of aluminium stocks stored in warehouses. If a portion of these stocks were to be released onto the market, that may have
a material effect on the aluminium price.

Alumina Limiteds net income is affected by movements in the prices of
aluminium and alumina.

Alumina Limiteds source of income is dividends derived from AWAC. The revenue of AWAC (40%
ownership of AWAC is the principal asset of Alumina Limited) is derived from sales of alumina, alumina-based chemicals and aluminium. The price that can be obtained for these products is influenced by global prices of alumina and aluminium, and in
particular, index prices for alumina and the LME price of primary aluminium. Pricing mechanisms for alumina have changed over time from primarily long term contracts with pricing expressed as a percentage of the aluminium price, to shorter term
contracts. Pricing has historically been based on a percentage of traded LME aluminium contract, however there is increased momentum for the industry to move away from LME linked contracts.

The price of aluminium is frequently volatile and changes in response to general economic conditions, expectations for supply and demand
growth or contraction, and the level of global inventories. The influence of hedge funds and other financial institutions participating in commodity markets has also increased in recent years, contributing to higher levels of price volatility.
Continued high LME inventories could lead to a reduction in the price of aluminium. A sustained weak aluminium pricing environment or deterioration in aluminium prices could have a material, adverse effect on AWACs business, financial
condition, results of operations or cash flow. The development of new alumina refineries and aluminium smelters, and increased production by new or existing alumina and aluminium producers may create oversupply or overcapacity, which could reduce
future prices of alumina, alumina-based chemicals and aluminium, thereby adversely affecting AWACs, and also Alumina Limiteds, profitability.

Over the last year or more, LME aluminium prices have traded at depressed levels (at near record lows in real terms). A large amount of global operating capacity is currently operating on a cash negative
basis, even after taking into account high regional premiums. Continuing depressed prices may see further curtailments or closures which would reduce demand for alumina.

KEY INFORMATION







AWACs and Alumina Limiteds financial performance and ability to service
liabilities, pay dividends and undertake capital expenditure would be adversely affected by a material fall in the prices of alumina and aluminium.

AWAC earnings are also influenced by the accounting for embedded derivatives in Alcoa of Australia Limiteds (AofA) contracts for the supply of natural gas and electricity. If the aluminium price as
quoted on the LME at a period end, and the estimate of long term aluminium prices in any relevant period beyond the period covered by forward LME prices, are higher than at the commencement of that period, a charge against income would result.
Conversely, a fall in those aluminium prices would result in a credit to income for the period. Those effects on AWAC income would have a corresponding proportional negative or positive impact on Alumina Limiteds income for the period.

In 2010, AWAC indicated it would seek to price its new third party alumina contracts on a basis using alumina indices for
2011 rather than a percentage of the LME-based aluminium price. AWAC based all new contracts entered in the second half of 2010 on the alumina price indices. These contracts are for delivery in 2011 and beyond. AWAC believes that this change, which
applies to approximately 54% of third party smelter grade alumina shipments by the end of 2013 and is expected to increase substantially over a number of years as annual contracts expire, will more fairly reflect the fundamentals of alumina. There
can be no assurance that such index pricing ultimately will be accepted as future LME-linked sales contracts expire or that such index pricing will result in consistently greater profitability from sales of alumina.

AWACs revenue will fluctuate in accordance with changes in the alumina price indices upon which some of AWACs alumina is
sold. The index prices may go up or down due to numerous factors outside Alumina Limiteds control such as supply and demand of alumina, the industrys capital and operating costs, general economic conditions and other factors. There is
currently a surplus of alumina production and that is affecting the market price of alumina.

For a statement of current
hedging, and movements in the selling price of aluminium over the last five years, see Item 11 Quantitative and Qualitative Disclosure about Market Risk.

Fluctuations in exchange rates can have a significant effect on Alumina Limiteds earnings, profitability and construction costs.

AofA accounts for approximately 60% of AWACs production. While a significant proportion of AofAs costs are incurred in
Australian dollars, sales are denominated in US dollars. AWACs future profitability (and therefore that of Alumina Limited) has been and may continue to be adversely affected by a strengthening of the Australian dollar against the US dollar.
AWACs profitability and financial position may also be adversely affected by a weakening of the US dollar against other currencies in which operating or capital costs are incurred by AWACs refineries outside Australia.

An increase in the cost of key inputs could reduce Alumina Limiteds profitability.

Changes in AWACs costs have a major impact on Alumina Limiteds profitability. AWACs mining, refining and smelting
operations are subject to conditions beyond its control that can delay deliveries or increase costs for varying lengths of time. These conditions include increases in the cost of key inputs including increases in the cost of raw materials (including
energy, caustic soda, bauxite and carbon products, labour and freight) and the non-availability of key inputs.

A key risk in
the cost of production of alumina and aluminium is the cost of energy. Alumina refineries and aluminium smelters consume substantial amounts of energy in their operations. The costs and profitability of AWACs alumina refineries and aluminium
smelters can be affected by:



| |  |  | significant increases in domestic or world electricity, coal, natural gas and oil prices;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | unavailability of electrical power or other energy sources due to insufficient supplies, whether due to lack of reserves or due to droughts, hurricanes
or other natural causes;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | curtailment of one or more refineries or smelters due to an inability to extend energy contracts upon expiration or to negotiate new arrangements on cost-effective terms or unavailability of energy at competitive prices.

KEY INFORMATION







AWAC may not be able to offset fully the effects of higher raw material costs or energy
costs through price increases, productivity improvements or cost reduction programs. Similarly, AWACs operating results are affected by significant lag effects for declines in key costs of production that are commodity or LME-linked. For
example, declines in 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. In recent years, increases in the alumina price have not kept pace with increases in
costs of alumina production, with the result that there has been a reduced margin in alumina refining. There is a risk that in the future such index pricing will not be accepted and, despite the changes in methods of alumina pricing that cost
increases will not be adequately covered by a correspondingly higher alumina price.

Other events could increase
AWACs production costs or decrease its production and therefore reduce Alumina Limiteds profitability.

In
addition to any increase in the cost of AWACs key inputs discussed previously, certain events which may be beyond AWACs or Alumina Limiteds control can decrease production, delay deliveries or increase costs for varying lengths of
time. These include weather and natural disasters, fires or explosions at facilities, unexpected maintenance or technical problems, key equipment failures, disruptions to or other problems with infrastructure, war or terrorist activities and
variations in geological conditions. In addition, industrial disruptions, loss of key staff, work stoppages, refurbishments and accidents at operations can result in production losses and delays in the delivery of product, which may adversely affect
profitability. In 2009, a fire at the Varanus Island gas processing facility in Western Australia significantly affected gas supply to AofAs alumina refineries.

Certain costs are also affected by government imposts and regulations in the countries in which AWAC operates. AWACs costs depend upon the efficient design and construction of mining, refining and
smelting facilities and competent operation of those facilities.

Alumina Limiteds ability to raise funds and
refinance its debt is subject to external factors.

Alumina Limiteds ability to refinance its debt on favourable
terms as it becomes due or to repay the debt, its ability to raise further finance on favourable terms, and its borrowing costs, will depend upon a number of factors, including AWACs operating performance, general economic conditions,
political, capital and credit market conditions, external credit ratings and the reputation, performance and financial strength of Alumina Limiteds business.

Debt which has recently been refinanced, or which may be refinanced in the future, may be at higher interest margins than previously held debt.

If a number of the risks outlined in this section eventuate, including deterioration in the Australian and global credit markets, or if
Alumina Limiteds operating performance, external credit rating or profitability is negatively impacted as a result of these risks, there is a risk that Alumina Limited may not be able to refinance any expiring debt facilities or the costs of
refinancing its debt may increase substantially.

There can be no assurance that any rating assigned will remain in effect for
any given period of time or that a rating will not be lowered, suspended or withdrawn entirely by a rating agency, if, in that rating agencys judgment, circumstances so warrant. Maintaining an investment-grade credit rating is an important
element of Alumina Limiteds financial strategy. A downgrade of Alumina Limiteds credit ratings could adversely affect the market price of its securities, adversely affect existing financing, limit access to the capital or credit markets
or otherwise adversely affect the availability of other new financing on favourable terms, if at all, result in more restrictive covenants in agreements governing the terms of any future indebtedness that Alumina Limited incurs, increase the cost of
borrowing, or impair its financial condition. In addition, Alumina Limiteds primary assets consist of its interests in the various companies that make up AWAC. Although Alumina Limited does not hold itself out as, or carry out its operations
as, an investment company as contemplated under the Investment Company Act of 1940, as amended (the Investment Company Act), uncertainty exists as to whether its interests in AWAC would be considered to be investment
securities under the Investment Company Act. If the AWAC interests are determined to be investment securities, Alumina Limited may be determined to be an investment company as defined in the Investment Company Act. As a non-U.S.
operating company, it is not practical or feasible for Alumina Limited to register as an investment company under the Investment Company Act. While the uncertainty regarding its status continues, Alumina Limited is constrained in its
ability to conduct capital raising activities in the U.S. capital markets as it is unable to register as an investment company under the Investment Company Act.

KEY INFORMATION







Alumina Limited does not hold a majority interest in AWAC, and decisions made by
majority vote may not be in the best interests of Alumina Limited.

AWACs strategic direction is determined by a five
member Strategic Council, consisting of three Alcoa Inc. representatives and two Alumina Limited representatives. An 80% majority is required to approve changes that effect:



| |  |  | a change of the scope of AWAC
| | - |  | -----------------------------



| |  |  | a change in AWACs dividend policy
| | - |  | ----------------------------------



| |  |  | sale of all or a majority of the assets of AWAC
| | - |  | -----------------------------------------------



| |  |  | equity calls on behalf of AWAC totalling, in any one year, in excess of $1 billion
| | - |  | ----------------------------------------------------------------------------------



| |  |  | loans to Alcoa, Alumina Limited or their respective affiliates by AWAC entities (including loans between AWAC entities).
| | - |  | ------------------------------------------------------------------------------------------------------------------------

AWACs decisions are otherwise by majority vote. Alcoa has a 60% interest in AWAC and has a majority vote. Subject to the
application of fiduciary duties, it may occur that AWAC decisions by majority vote are not in the best interests of Alumina Limited.

Alumina Limiteds cash flows depend on the availability of distributions from AWAC.

Alumina Limiteds cash flows are generated almost exclusively from distributions made by AWAC, by way of dividend or capital return. AWACs partners determine the timing and magnitude of AWAC
dividends and capital returns, subject to the relevant provisions of the AWAC Agreements. Alumina Limited cannot unilaterally determine AWACs dividend policy or the quantum or timing of dividends to be paid by AWAC. AWAC must distribute by way
of dividends, in each financial year, at least 30% of the net income of the prior year of the entities comprising AWAC, unless the Strategic Council agrees by an 80% majority vote to pay a smaller dividend.

During 2006, the AWAC partners entered into the Enterprise Funding Agreement, under which capital expenditures are to be funded by the
partners contributing directly to cash calls issued by the relevant AWAC entity. During 2010, the Enterprise Funding Agreement was extended on the basis that two years notice is required to terminate the Enterprise Funding Agreement. When such cash
calls are issued, additional dividends equal to the amount of the cash call will, subject generally to availability of cash and earnings, be paid by AWAC entities to the partners. The Enterprise Funding Agreement is expected to substantially reduce
the risk, during the term of the agreement, of only the minimum 30% dividend being paid during times of AWAC growth capital expenditure.

An increase in the capital costs of AWACs growth projects and operations would impact Alumina Limiteds cash flows and profitability.

A significant increase in the capital costs associated with AWACs growth projects and operations or delays in commissioning of the
projects would impact Alumina Limiteds cash flow and profitability.

Capital costs for development of an alumina
refinery and other mineral processing projects have increased substantially in recent years.

Regulatory change by
governments in response to greenhouse gas emissions may represent an increased cost to AWAC.

Energy is a significant input
in a number of AWACs operations. AWAC uses electricity in its operations and is an emitter of greenhouse gases. 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.

The previous Australian (Labour) Government passed legislation for
its carbon pricing scheme. The scheme operates in two phases: a fixed (but increasing) carbon permit price that commenced on July 1, 2012 to be followed by a floating price phase from July 1, 2015. The scheme is to cover emissions from the
stationary energy, industrial processing, mining and waste sectors. Entities that have operational control of a facility that emits more than 25,000t CO2-e per annum in greenhouse gas emissions from activities covered by the scheme are required to surrender carbon permits to
cover those emissions. Emissions-intensive trade-exposed industries and coal-fired power generators are eligible to receive assistance, primarily in the form of free carbon permits, under arrangements that are broadly similar to those that would
have applied under the former Carbon Pollution Reduction Scheme. Contractual arrangements

govern the electricity and domestic gas pass-through of carbon costs for indirect emissions. Aluminium smelting and alumina refining initially receive a
free allocation of permits for 94.5% of average industry emissions, per tonne of production. These allocations are based on the tonnes produced at an average emissions intensity. Allocations reduce at a rate of 1.3% per annum with a floor at
90% if a sector can demonstrate that less than 70% of its competitors have introduced comparable carbon constraints. The fixed price phase started at A$23.00 per tonne CO2-e and increases to $24.15 in year 2 and $25.40 in year 3 (based on a 2.5% rise with 2.5% inflation). From July 1,
2015 there will be an emissions trading scheme based on a national emissions cap for the first five years to be announced in 2014. Banking of surplus permits will be allowed and 50% of an entitys obligation may be met through international
credits/permits.

The current Australian (Coalition) Government has announced that it intends to abolish this carbon pricing
scheme with effect from July 1, 2014. This Government introduced the Clean Energy Legislation (Carbon Tax Repeal) Bill 2013 and related bills to the House of Representatives in November 2013 to abolish the scheme and the laws passed the House.
On March 20, 2014 the Senate voted against the bills related to the repeal of the scheme. The Government is expected to reintroduce the bills in July 2014, when new members join the Senate.

The Government intends to replace the scheme with a direct action plan as its main policy to meet a target of cutting greenhouse gas
output. If and when the Government may be able to abolish the current scheme and how the proposed direct action plan would affect AWAC are uncertain.

In the 2012/2013 year, AWAC in Australia produced 7.1 million tonnes of emissions from smelting (0.7 million tonnes from direct and 6.4 million tonnes from indirect sources) and
5.1 million tonnes of emissions from mining and refining (4.3 million tonnes from direct and 0.8 million tonnes from indirect sources). Further details are available on Alumina Limiteds website. Alcoa Inc announced on
February 18, 2014 that it will close the Point Henry aluminium smelter (one of the two AWAC smelters) in August 2014.

Other current and emerging legislation (such as existing and potential carbon trading schemes and the Australian and other mandatory
renewable energy target scheme and expanded scheme) may also affect energy prices and costs. These regulatory mechanisms may be either voluntary or legislated. The Australian Renewable Energy Target (RET) legislation requires that purchasers of
wholesale electricity (liable entities) source a defined percentage of their power from renewable sources and, where this is impractical, pay either a shortfall charge or purchase Renewable Energy Certificates (RECs) from renewable generators or the
market place. Liable entities will typically pass these additional costs onto their electricity customers, such as AWAC. The RET includes some provisions for exemption for energy-intensive trade-exposed industries which will reduce RET-related
costs.

Inconsistency of regulations may also change the attractiveness of the locations of some of AWACs assets. It is
difficult to assess the potential impact of future climate change regulation given the wide scope of potential regulatory change in countries in which Alumina Limited and AWAC operate.

AWAC 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 AWACs operations directly or indirectly through customers or AWACs supply chain.

AWAC may realise 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 AWAC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 AWACs operations.

Impact of global economic downturn.

Both Alumina Limiteds and AWACs operating and financial performance are influenced by a variety of general economic and
business conditions, including changes to monetary policy, fiscal policy, interest rates, foreign currency exchange rates, tax rates, commodity prices and inflation across the range of countries in which Alumina Limited and AWAC operate.

In particular, Alumina Limiteds future financial performance and condition may be influenced by the demand for alumina,
alumina-based chemicals and aluminium, which is currently supported by the industrialisation and

urbanisation of China and other developing countries. Decline in the rate of economic growth of these developing countries or reduction in demand for these products, could adversely affect
Alumina Limiteds future financial performance.

A reduction in demand for, or prices of AWACs products may require
a curtailment or closure of production capacity at AWACs operations. A curtailment of an operations production capacity generally results in an increase in the cost of production per tonne of output and can also result in additional
costs, including redundancy costs and continuing contractual purchase commitments for production inputs. Closure or change in ownership of production capacity at AWACs operations may result in an impairment loss being incurred in the profit or
loss as a result of the carrying value of an asset exceeding its recoverable value.

Some of AWACs operations are
conducted by joint ventures with external parties. To the extent that AWACs joint venturers do not meet their respective share of joint venture financial obligations, AWAC and Alumina Limited may be required to bear a disproportionate share of
joint venture obligations, including provision of funding. A deterioration in global economic conditions may also affect the financial position and consequent performance by contractual counterparties of AWAC of obligations owed to AWAC.

Alumina Limited could be adversely affected by changes in the business or financial condition of one or more of a significant supplier, a
joint venturer or a significant customer.

Changes to sales agreements could adversely affect Alumina Limiteds
results.

AWACs revenue from existing sales agreements depends on a variety of factors, such as price adjustments and
other contract provisions. The modification or termination of a substantial portion of AWACs sales volume could adversely affect its results and financial performance, to the extent that AWAC is unable to renew contracts or find alternate
buyers for production at the same level of profitability.

A reduction in demand (or lack of increased demand) for
aluminium by China or a combined number of other countries could negatively impact AWACs results.

The aluminium
industrys demand is highly correlated to economic growth. The Chinese market is a significant source of global demand for commodities, including aluminium and alumina. A sustained slowdown in Chinas economic growth, or the combined
slowdown in other markets, could have an adverse effect on the demand for aluminium and alumina and their prices. In addition, Chinas investments to increase its self-sufficiency in aluminium and alumina may impact future demand and supply
balances and prices.

AWAC is exposed to regulatory and court action, each of which could adversely affect Alumina
Limiteds results.

Governments extensively regulate AWACs mining and processing operations. National, state and
local authorities in Australia and other countries in which AWAC operates regulate the mining industry with respect to matters such as employee health and safety, permitting and licensing requirements and environmental compliance, plant and wildlife
protection, reclamation and restoration of mining properties after mining is completed, and the effects that mining has on groundwater quality and availability. Numerous governmental permits and approvals and leases are required for AWACs
mining and processing operations. Some governmental operating licences expire on a short term basis and renewals must be regularly sought. AWAC is required to prepare and present to national, state or local authorities, data pertaining to the effect
or impact that any proposed exploration or production activities may have upon the environment. The costs, liabilities and requirements associated with these regulations may be costly and time-consuming and may delay commencement or continuation of
exploration, expansion or production operations. Failure to comply with the laws regulating AWACs businesses may result in sanctions such as fines or orders requiring positive action by AWAC which may involve capital expenditure or the removal
of licences and/or the curtailment of operations. This relates particularly to environmental regulations.

The costs of
complying with such laws and regulations, including participation in assessments and clean-ups 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 AWAC 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 AWAC, sites owned by its
predecessors or sites that AWAC may acquire in the future. Alumina Limited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.

KEY INFORMATION







AWAC has obligations under various laws, licences and permits for the rehabilitation
(including remediation and/or restoration) of land used in bauxite mining, alumina refining, aluminium smelting and related activities. AWAC recognises these obligations and provides for Asset Retirement Obligations under US GAAP. Alumina Limited
recognises and provides for additional amounts for certain AWAC Asset Retirement Obligations as required by IFRS.

The
possibility exists that new legislation or regulations may be adopted which may materially adversely affect AWACs mining and processing operations or AWACs cost structure. New legislation or regulations or more stringent interpretations
or enforcement of existing laws and regulations may also require AWACs customers to change operations or incur increased costs. These factors and legislation, if enacted, could have a material adverse effect on AWACs, and hence Alumina
Limiteds, financial condition and results of operations.

Uncertainty of development projects and production
performance could adversely affect AWACs ability to sustain production and profitability levels.

AWACs ability
to sustain or increase its current level of production, and therefore its (and hence Alumina Limiteds) potential revenues and profits, in the medium to long-term is partly dependent on efficient operation of its facilities, the development of
new projects and on the expansion of existing operations. No assurance can be given that the planned development and expansion projects will result in the anticipated construction cost being achieved, the entire anticipated additional production or
that operation of existing facilities will be at desired rates of production. The economics of any project are based upon, among other factors, estimates of mineral deposits, recovery rates, production rates, capital and operating costs and future
commodity prices and exchange rates. There is no assurance that those estimates will be realised, or that actual economic conditions might not cause the profitability of projects to be materially different to that estimated at the time the projects
were approved.

Alumina Limited is liable for further capital calls under the AWAC arrangements.

AWAC may make annual capital calls of Alumina Limited and Alcoa of up to $1 billion in aggregate following approval by a majority vote of
AWACs Strategic Council, and of more than $1 billion in aggregate following approval by a super majority vote of the Strategic Council.

Alumina Limited is required to fund its share of the calls, subject to the provisions of the AWAC Agreements. If Alumina Limited is unable or unwilling to obtain equity or debt funding or has insufficient
retained earnings (i.e. cash) to fund its share of capital requirements up to $1 billion, it may ultimately run the risk of its equity interest in AWAC being diluted. Accordingly, there is a risk that Alumina Limited will be unable to fund a capital
call made by AWAC in the future, and that its interest in AWAC could be diluted. To the extent the aggregate annual capital calls that are approved are in excess of $1 billion and Alumina Limited is unable or unwilling to fund its share of such
capital calls, Alumina Limiteds equity interest in AWAC is not diluted. However, Alcoa will be otherwise compensated in respect of its funding of such annual calls above $1 billion, possibly by means of a disproportionate allocation of returns
associated with the excess contribution by Alcoa Inc.

The $1 billion threshold in respect of the funding of AWACs
capital requirements will be increased by the amount of relevant dividends paid in the relevant year with respect to valid calls to the extent they are funded by equity contributions in accordance with the Enterprise Funding Agreement. The $1
billion threshold above which super majority approval is required is not subject to increase in this way.

In addition to
capital calls to fund existing AWAC projects, Alcoa Inc could sell assets to AWAC or cause AWAC to purchase assets. The purchase of these assets by AWAC may require a proportionate investment from Alumina Limited.

Unavailability of bauxite may reduce AWACs profitability.

AWACs production of alumina is dependent upon continuing availability of bauxite supply. AWAC obtains bauxite from bauxite deposits
to which it has access under mining leases and under short term and long term contracts.

With respect to the Paranam refinery
in Suriname, at current rates of production it is likely that all Suriname currently developed bauxite deposits will be exhausted within the next two years. AWAC is actively exploring and evaluating alternate sources of bauxite in Suriname and its
options in relation to the future operations of the refinery.

There are numerous uncertainties inherent in estimating ore
reserves, including subjective judgements and determinations that are based on available geological, technical, legal and economic information. Previously valid assumptions may change significantly with new information, which may result in changes
to the economic viability of some reserves and the need for them to be restated.

KEY INFORMATION







Political and economic risks exist in some of the countries in which AWAC operates.

AWAC operates in a number of countries, some of which have a relatively high level of political, commercial and economic
risk. Political activities in these countries may be destabilising and disruptive to AWACs operations. Risks include those associated with political instability, civil unrest, expropriation, nationalisation, renegotiation or nullification of
existing agreements, mining lease and permits, restrictions on repatriation of earnings or capital and changes in local laws, regulations or policies. The impact of any such disruption could range from a minor increase in operating costs or taxes to
a material adverse impact, such as the closure of an operation. Risks relating to bribery and corruption may also be prevalent in some of the countries in which AWAC operates.

The future trading price of shares is subject to uncertainty

Investors
should be aware that there are risks associated with any share or ADR investment. The value of shares or ADRs may rise above or fall depending on the financial condition and operating performance of Alumina Limited or AWAC. Further, the price at
which shares or ADRs trade may be affected by a number of factors unrelated to the financial and operating performance of Alumina Limited or AWAC and over which Alumina Limited and its Directors have no control. These external factors include:



| |  |  | economic conditions in Australia and overseas;
| | - |  | ----------------------------------------------



| |  |  | relative changes in foreign exchange rates;
| | - |  | -------------------------------------------



| |  |  | the impact of significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving Alumina
Limited, AWAC or their competitors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | local and international stock market conditions;
| | - |  | ------------------------------------------------



| |  |  | changes in government regulations or in fiscal, monetary and regulatory policies (such as environmental and land management, regulation, taxation and
interest rates);
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | industrial disputes;
| | - |  | --------------------



| |  |  | geo-political conditions such as acts or threats of terrorism or military conflicts; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | volatility of comparable companies share prices, including Alcoa Inc.
| | - |  | ----------------------------------------------------------------------

There is no guarantee of profitability, dividends, return of capital, or the price at which shares or ADRs will trade. No assurances can
be given that the shares or ADRs will not be adversely affected by market fluctuations or other factors. The past performance of the shares and ADRs is not necessarily an indication as to future performance as the trading price of shares and ADRs
can fluctuate.

AWAC could be required to make additional contributions to its defined benefit pension plans as a result of
adverse changes in interest rates and the capital markets.

Estimates of liabilities and expenses for pensions and other post-retirement benefits incorporate significant assumptions, including the interest rate used to discount the future estimated liability, the long term rate of return on plan assets and several assumptions relating
to the employee workforce (salary increases, medical costs, retirement age and mortality). AWACs results of operations, liquidity or shareholders equity in a particular period could be affected by a decline in the rate of return on plan
assets, the interest rate used to discount the future estimated liability, or changes in employee workforce assumptions.

Operation of the AWAC Agreements could act as a disincentive to a potential acquirer of Alumina Limited.

The AWAC Agreements provide that AWAC is the exclusive vehicle for the pursuit of Alumina Limiteds and Alcoas interests in the
bauxite, alumina and inorganic industrial (alumina-based) chemicals businesses included within the scope of AWAC. Neither party may compete, within that scope, with AWAC so long as it maintains an ownership interest in AWAC.

##### Table of Contents

KEY INFORMATION







Any acquirer of Alumina Limited would become an affiliate of Alumina Limited
or Alcoa (as relevant) and trigger the application of the exclusive vehicle provisions contained in the AWAC Agreements in respect of the business and interests of the acquirer. If the acquirer already operates a bauxite, alumina or industrial
(alumina-based) chemicals business, the exclusive vehicle provisions would be contravened. Therefore, the exclusive vehicle provisions contained in the AWAC Agreements could act as a disincentive to a potential acquirer or bidder for Alumina
Limited.

The AWAC Agreements are silent on the action that Alumina Limited or Alcoa (as relevant) and the acquirer must take
to avoid any contravention. It is possible that the relevant business could be offered to AWAC for purchase, with the value to be agreed. Alternatively, the acquirer might divest itself of the relevant business or undertake some other action
consistent with the exclusive vehicle provisions of the AWAC agreements.

Native title in Australia poses risks to the
status of some of AWACs properties.

Native title describes the rights and interests of Aboriginal and
Torres Strait Islander people in land and waters according to their traditional laws and customs that are recognised under Australian law. There are current claimant applications for native title determinations in the Federal Court of Australia over
areas that include some of AofAs operations. Court decisions and various pieces of legislation make it evident that there are complex legal and factual issues affecting existing and future AofA interests. At this stage, we cannot make any
assessment of the impact of the recent and pending court cases on AWACs operations or the current claimant applications for native title over AWACs operations. See Item 8A Legal Proceedings  Native Title in Australia.

Alumina Limited faces significant competition in the aluminium market.

The markets for most aluminium products are highly competitive. AWACs, and hence Alumina Limiteds, competitors include a
variety of companies in all major markets. Additionally, aluminium competes with other materials such as steel, plastics, composites and glass. The willingness of customers to accept substitutes for aluminium and other developments by or affecting
AWACs competitors or customers could adversely affect AWAC, and hence Alumina Limiteds results of operations.

AWACs non-controlled assets may not comply with its standards

Some of AWACs assets are controlled and managed by its partners or by other companies. Management of non-controlled assets may not
comply with its management and operating standards, controls and procedures. Failure to adopt equivalent standards, controls and procedures at these assets could lead to higher costs and reduced production and adversely impact results and
reputation.

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

AWAC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 AWAC. This may include 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. AWAC 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. AWAC could be subject to fines, penalties, damages (in certain cases, treble damages), or suspension or debarment from government contracts. While AWAC 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 AWAC 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 unfavourable changes in laws, regulations or policies, or other contingencies that AWAC cannot predict with certainty could have a material adverse effect
on AWACs results of operations or cash flows in a particular period. See Item 8A Legal Proceedings  AWAC Litigation.

Alumina Limiteds reported results could be adversely affected by the impairment
of assets and goodwill

Alumina Limited may be required to record impairment charges as a result of adverse developments in
the recoverable values of its assets (including goodwill recorded by AWAC). Significant assumptions in the determination of recoverable value include, but are not limited to: pricing of the Groups commodities and products, reserves and
mineralised material, discount and exchange rates, operating cost projections, and timing of expenditure on major projects. In addition, the occurrence of unexpected events that adversely impact the Companys business may have an impact on the
assumptions underlying the recoverable value of its assets. To the extent that the recoverable value of an asset is impaired, such impairment may negatively impact Alumina Limiteds profitability during the relevant period. Closure, curtailment
or sale of AWACs operations may result in an impairment being incurred as a result of the carrying value of an asset exceeding its recoverable value and redundancy costs.

|ITEM 4. | INFORMATION ON THE COMPANY
|------- | --------------------------

A. History and Development of the Company

Alumina Limited was incorporated in 1970. In 1979 it became the holding company of the WMC Group which commenced operations in 1933. The Company was previously called WMC Limited until it changed its name
to Alumina Limited in December 2002 as part of the demerger of the WMC Group. The demerger was effected through an Australian court-approved scheme of arrangement and associated capital reduction and dividend distribution.

At December 31, 2013, Alumina Limited had total consolidated assets of $3.0 billion. Aluminas profit from continuing
operations was $0.5 million for the year ended December 31, 2013 ($55.6 million loss for the year ended December 31, 2012). The Company is listed on the ASX. On February 6, 2014, Alumina Limited announced its intention to delist from
the NYSE and formerly delist from the NYSE prior to opening of trading on February 28, 2014. The Company immediately commenced trading on the OTC market under the ticket code: AWCMY.

Alumina Limited, incorporated under the laws of the Commonwealth of Australia, has its registered office and principal executive offices
at Level 12, 60 City Road, Southbank, Victoria, 3006, Australia. Its telephone number is +61 3 8699 2600 and facsimile number is +61 3 8699 2699. Enquiries about Alumina Limiteds ADRs should be addressed to
its depositary, The Bank of New York Mellon, telephone +1 (212) 815 2293 or facsimile +1 (212) 571 3050, located at 101 Barclay Street, New York, NY 10286.

Alumina Limiteds primary assets are its interests in AWAC with Alcoa Inc. AWAC has interests in bauxite mining, alumina refining
and two operating aluminium smelters. Alcoa is the operator of AWAC and provides the Combined Financial Statements to Alumina Limited.

The Demerger

On December 11, 2002, Alumina Limited demerged its
interest in AWAC from its nickel, copper/uranium and fertilizer businesses and exploration and development interests. The demerger was effected through an Australian court-approved scheme of arrangement and associated capital reduction and dividend
distribution. As a result of the demerger, Alumina Limited held the interest in AWAC, and WMC Resources Ltd, which prior to the demerger was a wholly owned subsidiary of WMC Limited, held the nickel, copper/uranium and fertilizer businesses and
exploration and development interests previously held within the WMC Limited group.

Change in Functional and Presentation
Currency

An entitys functional currency is the currency of the primary economic environment in which the entity
operates. With the commissioning of production at the Juruti mine and the Alumar refinery in Brazil completed, Alumina Limited reached the end of the investment program in Brazil. Greater production and cash flows to shareholders was expected from
those assets in the future. Most dividends are also received in US dollars. Consequently, Alumina Limited announced in February 2010 its Boards decision to change Alumina Limiteds functional currency from Australian dollars to US
dollars, effective January 1, 2010.

Following the change in functional currency, Alumina Limited elected to change its
presentation currency from Australian dollars to US dollars from January 1, 2010. The change in presentation currency represents a voluntary change in accounting policy, which has been applied retrospectively.

To give effect to the change in functional and presentation currency, the assets, liabilities, contributed equity, reserves and retained
earnings of entities with an Australian dollar functional currency as at December 31, 2009 were converted into US dollars at period end exchange rates of AUD/USD 0.8972. Revenue and expenses were converted at an average rate of AUD/USD 0.7123
for the six months ending June 30, 2009 and AUD/USD 0.8711 for the six months ending December 31, 2009 and AUD/USD 0.8519 for the 12 months ending December 31, 2008.

INFORMATION ON THE COMPANY







B. Business Overview

Alumina Limiteds sole business undertaking is in the global alumina and aluminium industry, which it conducts primarily through
bauxite mining and alumina refining, with some minor alumina based chemicals businesses, aluminium smelting and the marketing of those products. All of those business activities are conducted through its 40% investment in AWAC.

Alumina Limiteds net profit/(loss) is principally comprised of a return on its equity investment, and revenues are limited to small
amounts of interest income and occasional one-off revenues. This revenue is itemised separately in the profit or loss. The breakdown of AWAC revenue by geographical segment for the last three financial years is available within the notes to the
Combined Financial Statements for AWAC (Note B, page F-58).

AWAC was formed on January 1, 1995 by Alumina Limited and
Alcoa combining their respective global bauxite, alumina and alumina-based chemicals businesses and investments and their respective aluminium smelting operations in Australia. AWAC is the worlds largest producer of alumina and mining of
bauxite. Alumina Limiteds partner in AWAC is Alcoa, who owns the remaining 60% and manages the day-to-day operations.

This partnership provides investors with a direct investment in the alumina industry.

The Strategic Council is the principal forum for Alcoa and Alumina Limited to provide direction and counsel to the AWAC entities in
respect of strategic and policy matters. The Alcoa and Alumina Limited representatives on the Boards of the AWAC entities are required, subject to their general fiduciary duties, to carry out the directions and the decisions of the Strategic
Council. The Strategic Council has five members, three appointed by Alcoa (of which one is Chairman) and two by Alumina Limited (of which one is the Deputy Chairman). Decisions are made by majority vote except for matters which require a super
majority vote, which is a vote of 80% of the members appointed to the Strategic Council.

The following decisions
require a super majority vote:



| |  |  | change of the scope of AWAC
| | - |  | ---------------------------



| |  |  | change in the minimum 30% dividend policy
| | - |  | -----------------------------------------



| |  |  | sale of all or a majority of the assets of AWAC
| | - |  | -----------------------------------------------



| |  |  | equity calls on behalf of AWAC totaling, in any one year, in excess of $1 billion
| | - |  | ---------------------------------------------------------------------------------



| |  |  | loans to Alcoa, Alumina Limited or their affiliates by AWAC entities (including loans between AWAC entities).
| | - |  | -------------------------------------------------------------------------------------------------------------

Under the general direction of the Strategic Council, Alcoa is the industrial leader and provides the operating management of
AWAC and of all affiliated operating entities within AWAC.

Alumina Limited is entitled to representation in proportion to its
ownership interest on the Board of each entity in the AWAC structure currently represented on AofA and Alcoa World Alumina Brasil Ltda (AWA Brasil). In addition to the Strategic Council meetings, Alumina Limiteds management and Board visit and
review AWACs operations each year.

Subject to the provisions of the AWAC agreements, AWAC is the exclusive vehicle for
the pursuit of Alumina Limiteds and Alcoas (and their related corporations as defined) interests in the bauxite, alumina and inorganic industrial chemicals businesses, and neither party can compete with AWAC so long as they maintain an
ownership interest in AWAC. In addition, Alumina Limited may not compete with the businesses of the integrated operations of AWAC (being the primary aluminium smelting and fabricating facilities and certain ancillary facilities that exist at the
formation of AWAC).

If either party acquires a new business which has as a secondary component a bauxite, alumina or
inorganic industrial chemicals business, that business must be offered to AWAC for purchase at its acquisition cost or, if not separately valued, at a value based on an independent appraisal of the business. Smelting is not subject to these
exclusivity provisions, although there are certain smelting assets in AWAC, being those in AofA, in which Alumina Limited already had an interest at the time AWAC was formed.

INFORMATION ON THE COMPANY







AWACs alumina production in 2013 was 15.8 million tonnes compared to
15.6 million tonnes in 2012. The Point Comfort refinery contributed most of this growth reflecting its improved stability. AWACs nameplate production capacity is 17.2 million tonnes per annum.

Alumina shipments were 16.1 million tonnes in 2013, 0.5 million tonnes higher than 2012, largely as a result of a catch up on
delayed December 2012 shipments, increased production and a reduction of historical levels of inventory.

Approximately 54% of
third party smelter grade alumina shipments were priced on spot or alumina indexed basis in 2013 compared to approximately 35% in 2012.

AWAC produces aluminium at two smelters in Australia. Production of approximately 354,000 tonnes in 2013 was lower compared to 2012, largely due to the Anglesea power station maintenance. The Anglesea
power station (owned by AofA) provides approximately 40% of the electricity needs for the Point Henry smelter. Statutory maintenance of the power station is required every four years and occurred during 2013. On 18 February 2014, Alcoa Inc
announced the permanent closure of the Point Henry aluminium smelter.

AWAC capital expenditure totalled $322.6 million, 14%
lower than 2012. Approximately $293.1 million was associated with sustaining capital, with the majority of this in Australia. The Australian expenditure included the relocation of the crusher facilities at the Huntley mine. Growth capital
expenditure mainly related to completion works of the Juruti mine infrastructure in Brazil. AWAC is also investing in green field growth with a view to ensuring that AWACs cost position remains globally competitive. The joint venture between
AWAC and Maaden for the construction of a green field mine and a refinery at Ras Al Khair in Saudi Arabia (AWAC interest of 25.1%) is AWACs major growth project and is due to come on stream in 2014. As at December 2013, the refinery was
approximately 77% complete and the mine was approximately 52% complete.

INFORMATION ON THE COMPANY







Bauxite Interests

Bauxite exploration, bauxite reserve determinations and bauxite mining development activities are conducted by Alcoa as the industrial
leader of AWAC.

AWACs bauxite deposits are large deposit areas with mining rights that expire in most cases more than
20 years from today. For purposes of evaluating the amount of bauxite that will be available to supply as feedstock to its refineries, AWAC 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 mineral 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 government factors. AWAC 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 AWAC to confidently establish the extent of its bauxite resources and their ultimate conversion to reserves.

The
table below only indicates the amount of proven and probable reserves controlled by AWAC. While the level of reserves may appear low in relation to annual production levels, they are consistent with historical levels of reserves for AWACs
mining locations. Given AWACs extensive bauxite resources, the abundant supply of bauxite globally and the length of AWACs rights to bauxite, it is not cost-effective to invest the significant resources necessary to establish bauxite
reserves that reflect the total size of the bauxite resources available to AWAC. Rather, bauxite resources are upgraded annually to reserves as needed by 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. AWAC 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 mines. Reserves are declared
in accordance with Alcoas internal guidelines as administered by the Alcoa Ore Reserve Committee (AORC) and has not been prepared in accordance with the Australasian Code for reporting of exploration results, mineral resources and ore
reserves. 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 aluminium
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. AWAC mining locations have annual in-fill drilling programs designated to progressively upgrade the reserve classification of their bauxite.

INFORMATION ON THE COMPANY







|6 | AWA LLC has a bauxite purchase contract with CBG that expires in 2029. Before that expiration date, AWA LLC expects to negotiate an extension of the
contract 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.

|9 | The mining rights in the Onverdacht and Coermotibo areas where Suralco has active mines extend until 2033. Onverdacht reserves were reclassified as
resources pending testing during 2014 to confirm ore characteristics. Proven reserves at Coermotibo were reclassified as probable reserves pending new density tests during 2014. Bauxite within these areas will likely be exhausted in the next two
years. During 2013, Suralco received for processing 12.7 thousand mt of Juruti high iron bauxite as test material. Alcoa is actively exploring and evaluating additional sources of bauxite in Suriname. During 2014, Suralco will be mining from
both reserves and resources. A feasibility study relating to the development of a mine at the Nassau Plateau is in progress.

AWAC is managed by Alcoa. The
ore reserves are prepared by Alcoa and are published as received from Alcoa. Where operations are not managed by Alcoa the reserves are published as received from the other managing company.

Australia  Darling Ranges Mines:Huntly and Willowdale are the two active mines in the Darling Ranges of Western Australia.
The mineral lease issued by the State of Western Australia to Alcoa 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 of December 31, 2013.
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  Juruti RN101, RN102, RN103, RN104, #34:Declared reserves are as of December 31, 2013.
All reserves are on Capiranga Pateau. 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.

Jamaica  Jamalco:Declared reserves are as of December 31, 2013. The declared reserve and annual production tonnages
are AWAC share only (55%). Declared reserves are in the following areas: Harmons Valley, South Manchester and Porus/Victoria Town. Current ore mining is in Harmons Valley, South Manchester and Porus/Victoria Town. Additional resources
remain in Harmons Valley, South Manchester, Porus/Victoria Town and North Manchester. Resources are in the process of being promoted to reserves as land acquisition, resettlement and access rights are secured. The Porus/Victoria Town
exploration license area was added to Jamalcos mining license (SML130) during 2013.

Suriname  Suralco 
Caramacca:During 2013, the Suriname Ministry of Mines notified Suralco that it is permitted to continue to mine at Caramacca while the application for renewal of the mining permit is pending Ministry action. Remaining bauxite at Caramacca has

INFORMATION ON THE COMPANY







Guinea  Boke  CBG:Declared reserves are as of
December 31, 2012 less the tonnage for 2013 shipments. 2013 shipment tonnage has been subtracted from the Proven Reserves. CBG issues a JORC compliant CP Report once per year. The declared reserves are based on export quality bauxite reserves.
Declared reserve tonnages are based on the AWAC share of CBGs reserves. Annual production tonnage reported is based on AWACs 22.95% share. Declared reserves quality is reported based on total alumina (TAI2O3) and total silica (TSiO2) because CBG export bauxite is sold on this basis. Additional deposits are being routinely drilled and modeled to upgrade
to reserves as needed.

bauxite deposits are mostly derived from the weathering of Tertiary Paleogene arkosic sediments. In a few spots the bauxite overlies Precambrian granitic and gneissic rocks which are now saprolite. Bauxitization likely occurred during the middle to
late Eocene Age. |  | Commercial grid power.                                                                            |  | In the Onverdacht mining areas the bauxite is mined and transported to the refinery by truck. In the Coermotibo mining areas the bauxite
is mined and stockpiled and then transported to the refinery by barge. Some of the ore is washed in a small beneficiation plant located in the
Coermotibo area. The main mining administrative offices and services and workshops and laboratory are located at the refinery in Paranam. The ore is crushed at Paranam. The mines and washing plant are operating.

INFORMATION ON THE COMPANY







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
aluminium complex in the Kingdom of Saudi Arabia. In its initial phases, the complex includes a bauxite mine with an initial capacity of 4.0 million bdmtpy; an alumina refinery with an initial capacity of 1.8 million mtpy; an aluminium
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 sheet, end and tab stock for the manufacture of aluminium cans, as well as other products to
serve the automotive, construction, and other industries.

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. First hot metal from the smelter was produced on December 12, 2012. The smelter reached production of 190,000 mtpy in 2013 and is expected to reach full capacity in
2014. The first hot coil from the rolling mill was produced in the fourth quarter of 2013 and the first automotive coil is expected in the fourth quarter of 2014. First production from the mine and refinery is expected in 2014.

Alcoa owns a 25.1% interest in the smelter and rolling mill, with AWAC having a 25.1% interest in the mine and refinery.

INFORMATION ON THE COMPANY







AWAC Operations

i) Smelter-Grade Alumina and Primary Aluminium

Australia

In Australia, AWAC partners own 100% of AofA which
operates mining, refining and smelting facilities. In 2013, the Australian operations produced 9.2 million tonnes of alumina (2012: 9.2 million tonnes) and 354 thousand tonnes of aluminium (2012: 358 thousand tonnes).

Alumina produced in Australia by AWAC is shipped either to its smelters at Point Henry and Portland in Victoria, Australia or to overseas
AWAC customers, principally in South Africa, the Middle East, South East Asia, Russia, China, South America and North America. Bauxite is sourced from its 100% owned Huntly and Willowdale bauxite mines, each located in the Darling Ranges south of
Perth, Western Australia, which supply AWACs three alumina refineries in Western Australia. The Pinjarra, Wagerup and Kwinana refineries have nameplate capacities of 4.2 million tonnes, 2.6 million tonnes and 2.2 million tonnes,
respectively. Bauxite is transported from the mines by overland conveyor to the Pinjarra and Wagerup refineries and by rail to the refinery at Kwinana.

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
capacity increase of over 2.0 million mtpy. This approval had a term of five years and included environmental conditions that must be satisfied before Alcoa can 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, AofA received approval from regulators
in Western Australia state for a five year deferral of the proposed multi-billion dollar expansion of the Wagerup alumina refinery. The states Environmental Protection Authority (EPA) recommended that the time limit for substantial
commencement of the Wagerup expansion, to a maximum capacity of 4.7 million tonnes a year, to be extended by five years. AofA needs to provide the EPA with written evidence that it has started work on the expansion by September 14,
2016, otherwise the authorization will lapse. There were no material developments in 2013.

A storage and loading facility at
the port of Bunbury, near Wagerup, handles the majority of shipping for the Pinjarra and Wagerup refineries. Some Pinjarra production is also shipped through the port facility at Kwinana, south of Perth.

The rights to operate bauxite mining and alumina refining operations in Western Australia are provided under agreements with the State
Government of Western Australia. The mining leases issued by the Western Australian Government extend to expire in 2024. The leases can be renewed for an additional twenty-one year period to 2045.

AofAs present sources of bauxite are sufficient to meet the expected requirements of its alumina refining operations for the
foreseeable future, based on current production rates and refining capacity.

The bauxite from the Darling Ranges, while
relatively low in alumina, is also low in reactive silica. This results in low consumption of caustic soda which in turn contributes to lower costs of production.

Alumina refining is energy intensive and AWACs refineries in Australia use natural gas as their energy source. The natural gas requirements of the refineries are supplied primarily under a contract
with parties comprising the North West Shelf Gas Joint Venture. The initial contract was scheduled to expire in 2005 and imposed minimum purchase requirements. In December 1997, these arrangements were extended through a renegotiation of the initial
contract and the signing of a new contract running through to 2020.

AofA has had several shorter term gas contracts to
supplement its principal gas supply contract. AofA is pursuing a number of replacement energy supply options to its refineries in view of the timing for expiry of existing energy supply contacts, including steam and power generation utilizing coal
based energy, recontracting for gas supplies and investing directly in projects that have the potential to deliver cost based gas.

INFORMATION ON THE COMPANY







AofA holds a 20% equity interest in a consortium that in October 2004 acquired the
Dampier to Bunbury Natural Gas Pipeline (DBNGP). This pipeline transports gas from the northwest gas fields to Alcoas alumina refineries and other users in the Southwest of Western Australia. AofA uses gas to co-generate steam and electricity
for its alumina refining processes at the Kwinana, Pinjarra and Wagerup refineries.

AWAC produces primary aluminium in
Victoria, Australia. The aluminium assets include an aluminium smelter at Point Henry, near Geelong, and a 55% controlling interest in an aluminium smelter at Portland, approximately 240 kilometres west of Geelong. AWACs interest in the
Portland smelter increased from 45% to 55% in 2000 following the acquisition of Eastern Aluminiums 10% interest. The Portland smelter has an annual production capacity of 358,000 tonnes of aluminium and Point Henry has an annual capacity of
190,000 tonnes.

In April 2009, it was announced that the smelting operations at Portland would be curtailed by 15% of
production by July 2009 resulting from the economic downturn and softened market demand.

Electricity for the Portland smelter
is purchased under a 30 year electricity supply agreement that expires in 2016. Electricity supplied under that agreement is generated from extensive brown coal deposits. The tariff applicable under the agreement has both a base component, which
reflects the cost of power generation and transmission, and a flexible or adjustable component, which provides for adjustments to the base tariff rate based on the LME price for aluminium. The agreement provides a discount for interruption and a
demand charge equal to about two thirds of the total tariff which may be payable whether or not energy is taken.

40% of the
electricity for the Point Henry smelter is supplied by AofAs generating station at Anglesea, with the balance purchased under a 30 year electricity supply agreement that expires in 2014. The rates under that agreement change with the LME price
of aluminium (similar to the Portland power arrangement described above). The contract includes a standby demand charge for the purchase of electricity for periods when the Anglesea generating station is not operating. An additional energy charge is
payable when this standby power is actually used.

On March 1, 2010, AofA announced new power hedge contracts had been
entered with AGL Loy Yang for the Portland and Point Henry aluminium smelters in Victoria, Australia until 2036. The contracts operate from 2014 for the Point Henry operations and 2016 for the Portland operations.

The power hedge contracts hedge the spot price for electricity in the National Electricity Market in relation to the Point Henry smelter
for some 22 years from August 2014, when the current contract with the State Electricity Commission of Victoria expires. AofA has terminated its Point Henry smelter power hedge contract with AGL Loy Yang, under the terms of that contract. This
action will not impact electricity supply agreements in place for the Portland aluminium smelter.

On February 18, 2014,
Alcoa announced the permanent closure of the Point Henry aluminium smelter. Total restructuring related charges associated with the Point Henry smelter are expected to total approximately $250 million after tax. The announcement also noted that the
Anglesea coal mine and power station, which supplies approximately 40% of the power needs for the Point Henry smelter, has the potential to operate as a standalone facility after the smelter closes. AofA is actively seeking a buyer for the facility.

United States

Point Comfort Refinery

AWAC owns 100% of an alumina refinery at Point
Comfort in Texas. The facility is located approximately 210 kilometres south of Houston on Port Lavaca Bay. Point Comforts port facilities are linked with the Gulf of Mexico via a 35 kilometre channel. The Point Comfort refinery,
which was completed in 1960 and expanded in 1997, has a nameplate capacity of 2.3 million tonnes per annum.

Bauxite for the refinery is sourced principally from an AWAC affiliate in Guinea. Point Comfort uses gas-fired cogeneration facilities to
supply process heat and power to the refinery, and gas is purchased from local suppliers under short term contracts.

##### Table of Contents

INFORMATION ON THE COMPANY







The Point Comfort refinery produces both smelter-grade alumina and alumina hydrates
(chemical-grade alumina). Most of the refinerys smelter-grade alumina is sold to Alcoas smelters in the United States.

The Point Comfort refinery is part of an area which has been declared a US national superfund site. Alcoa has agreed to undertake a remedial investigation and feasibility study at the site in
conjunction with the US Environmental Protection Agency to determine rehabilitation requirements. Alumina Limited is indemnified by Alcoa against environmental liabilities in relation to activities undertaken at Point Comfort prior to
January 1, 1995. This indemnity is specifically extended to the contamination that gave rise to the Point Comfort sites superfund status. Alcoa has also agreed that it will be 100% responsible for remediating the
contamination, as well as natural resource damages, which gave rise to the placement of the site on the National Priorities List and the entry of the Administrative Order on Consent issued on March 31, 1994, and any subsequent Order issued
relating to this contamination.

Republic Of Guinea

Halco Mining Bauxite Operation

AWAC has a 45% interest in a bauxite company, Halco (Mining) Inc. (Halco). Halco owns 100% of Boké Investment Company, a Delaware company, which owns 51% of Compagnie des Bauxites de Guinée
(Compagnie Guinée), the manager of a number of bauxite mines at Boké, north-west of Conakry, in Guinea, West Africa. The Guinean Government owns the remaining 49% of Compagnie Guinée. Compagnie Guinée has the exclusive
right through 2038 to develop and mine bauxite in certain areas within a 10,000 square-mile concession in north-western Guinea.

The shareholders of Halco take bauxite in proportion to their equity positions under take-or-pay contracts. AWAC, through AWA LLC, has a bauxite purchase contract with CBG that expires in 2029. Before that expiration date, AWA LLC expects to negotiate an extension of the contract 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.

Other Guinea Interests

In November 2005, AWA LLC and Rio Tinto Alcan Inc. 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 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 to November 2012 and has been recently extended again
until 2015. Pre-feasibility studies were completed in 2008. Additional feasibility study work was completed in 2012, and further activities continued in 2013.

Suriname

Suralco

AWAC owns the Suriname Aluminum Company (Suralco). Suralco began operations in 1916 and currently has interests in an alumina refinery at
Paranam, bauxite mines in north east Suriname and south of Paranam and hydro-electric facilities at Afobaka Lake.

The
2.2 million tonnes-per-annum alumina refinery at Paranam, in northern Suriname, was constructed in 1968 and sources bauxite from mines in Suriname. The refinery was owned by a joint venture held 55% by Suralco and 45% by an affiliate of BHP
Billiton Plc (BHP Billiton), with Suralco as manager of the joint venture and operator of the refinery. The joint venture parties shared alumina production from the refinery in proportion to their shareholdings and were separately responsible for
the marketing of their share of this production.

In July 2009, AWA LLC acquired the BHP Billiton subsidiary that was a 45%
joint venture partner in the Surinamese bauxite mining and alumina refining joint ventures. Prior to the AWA LLC buyout, BHP Billitons subsidiary held a 45% interest to Suralcos 55% interest in the two joint ventures. After the
acquisition of the BHP Billiton subsidiary, its name was changed to N.V. Alcoa Minerals of Suriname (AMS). AWA LLC is part of the AWAC group of companies.

INFORMATION ON THE COMPANY







In May 2009, a decision was made to protect the long-term viability of the industry in
Suriname. The curtailment was aimed at deferring further bauxite extraction until additional in-country bauxite deposits are developed and market conditions for alumina improve. As at December 31, 2013, 876,000 mtpy remains curtailed.

The Suralco refinerys current sources of bauxite and additional bauxite supply from two successor mines, Kaimangrassie
and Klaverblad in Eastern Suriname will be exhausted within the next two years. Alcoa is evaluating alternative sources of bauxite including deposits from Suralcos concession in eastern Suriname, such as the Nassau plateau.

Hydro-electric facilities at Afobaka Lake in Suriname are also operated by Suralco. The plant was constructed pursuant to the Brokopondo
Agreement between Suralco and the Suriname Government which was signed in 1958. The facilities supply electricity to the alumina refinery at Paranam and sell electricity to the Government of Suriname.

Jamaica

Jamalco Refinery

AWAC owns Alcoa Minerals of Jamaica LLC, a US based
company which holds a joint venture interest in Jamaica. The joint venture, called Jamalco, is owned 55% by AWAC and 45% by Clarendon Alumina Production Limited (Clarendon), which is a Jamaican Government company. The joint venture is governed by
agreements with the Jamaican Government which were finalized in 1988. Jamalco owns and manages bauxite mines, an alumina refinery and port facilities. Each joint venturer is responsible for marketing its share of production.

Bauxite for the refinery is sourced from leases in Harmons Valley and the Manchester plateau. The bauxite mines that feed the refinery
are located 40 kilometers north of the refinery in the Mocho Mountains. The bauxite mining rights are owned by Jamalco. Bauxite is transported to the refinery on a railway and by a rope conveyor which was commissioned in 2008, both of which are
owned by the joint venture. Jamalco also manages a port at Rocky Point, located south of the alumina refinery. The port is connected to the refinery by rail.

Jamalcos alumina refinery, completed in 1972, is located 72 kilometers west of Kingston. The refinerys nameplate capacity was 1.5 million tonnes per annum after completion of the
250,000 tonne expansion in November 2003. The completion of the expansion was part of an agreement to invest $115 million to expand the refinery and remove from Jamalco the nearly 30-year-old levy on bauxite.

The refinery produces smelter grade alumina. Energy for the refinery is provided by oil powered turbines. Any surplus power produced is
sold into the Jamaican public electricity grid and the refinery can draw power from the grid if necessary.

A 146,000 mtpy
capacity expansion of the Jamalco alumina refinery in Clarendon, Jamaica was completed in early 2007. As a result of 100% funding of the expansion, AWACs ownership of Jamalco increased to 55%.

Brazil

Alcoa World Alumina Brasil Ltda

Alcoa World Alumina Brasil Ltda, an AWAC
entity in Brazil, is a participant (18.9% prior to the recent expansion) in a consortium that owns the Alumar alumina refinery at São Luis in north eastern Brazil. The other consortium participants, and their ownership prior to the expansion,
are Alcoa Aluminio S.A. (35.1%), BHP Billiton Metais SA (36%) and an affiliate of Alcan Aluminio Do Brazil SA (10%). Alcoa Aluminio S.A. is the operator of the consortium which is managed on a production and cost sharing basis. Alcoa
World Alumina Brasil Ltda has special rights to 54% of any expansion of the Alumar refinery.

The nameplate capacity of the
refinery is approximately 3.5 million mtpy, and Alcoa World Alumina Brasil Ltda. owns 39% of the refinery. Construction of the refinery expansion was finalized at the end of 2009.



- 34 -

##### Table of Contents

INFORMATION ON THE COMPANY







The major source of energy for the refinery is low sulphur steaming coal purchased from
Colombia and Venezuela.

AWAC has long term bauxite purchase contracts with MRN which has mines located at Trombetas within
the State of Para in northern Brazil. Alcoa World Alumina Brasil Ltda holds a 9.6% interest in MRN. The remaining interest in MRN is jointly owned by affiliates of Alcan, Companhia Brasileira de Aluminio, Companhia Vale do Rio Doce, BHP Billiton
Metais S.A., Alcoa Aluminio S.A., and Norsk Hydro Brasil Ltda. MRNs mines produce approximately 18 million tonnes of bauxite a year. Bauxite is transported approximately 1,400 kilometers by ship to the refinery.

The AWAC share of the Alumar refinery expansion is supplied by the commissioned AWAC Juruti bauxite mine. The Juruti mine and associated
rail and port infrastructure is 100% owned by AWAC. Shipments of bauxite from the Juruti bauxite mine to the expanded Alumar refinery commenced in September 2009. The Juruti development has been constructed with the necessary infrastructure to
accommodate increasing production beyond the initial 2.6 million mtpy. During 2013, the Juruti mine operated with production levels as high as 4.4 million tonnes on an annualized basis.

Spain

San Ciprian Refinery

AWAC owns and operates the San Ciprian alumina
refinery, which is located on the north-west coast of Spain. AWAC acquired the refinery in February 1998 from Alcoa for $113 million following Alcoas acquisition of the principal alumina and aluminium assets of Spains state owned
aluminium producer, Industria Espanola del Aluminio (Inespal).

The San Ciprian refinery was commissioned in 1980. It has an
annual production capacity of 1.5 million tonnes, having completed a 0.2 million tonne expansion at a cost of $22.2 million in March 2001. San Ciprian operations are high temperature and pressure refining technology. Bauxite for the
refinery is shipped from the Boke mine in Guinea. Steam for the refinery is generated by the plants oil fired boiler, with electrical power supplied from the national power grid.

Approximately 70% of alumina produced at the San Ciprian refinery is smelter grade, which is sold primarily to Alcoas smelters in
Spain. The balance of production is non-smelter grade alumina that is largely sold as commodity hydrate alumina to chemical manufacturers. A small portion of the non-smelter grade alumina is also sold as calcined aluminas. The location of
San Ciprian within the European Union allows commodity grade alumina to be sold within Europe without attracting the relatively high tariffs imposed on non-European suppliers.

In 2012, AWAC began to convert the energy supply at the San Ciprian refinery in Spain from oil to gas in order to improve the
competitiveness of this facility. This work continued during 2013 and is anticipated to be completed in January 2015.

Vietnam

In 2008, AWAC signed a cooperation agreement with Vietnam National Coal-Minerals Industries Group (Vinacomin) in which they agreed to conduct a joint feasibility study of the Gia Nghia bauxite mine and
alumina refinery project located in Dak Nong Province in Vietnams Central Highlands, with first stage capacity expected to be between 1.0 and 1.5 million mtpy. The cooperation between AWAC and Vinacomin on Gia Nghia is subject to approval
by the Government of Vietnam. If established, the Gia Nghia venture is expected to be 51% owned by Vinacomin, 40% by AWAC and 9% by others. There were no material developments in 2013.

Kingdom of Saudi Arabia

In December 2009, Alcoa Inc and Maaden entered into a joint venture to develop a fully integrated aluminium complex in the Kingdom of Saudi Arabia. In its initial phases, the complex includes a
bauxite mine with an initial capacity of 4.0 million mtpy; an alumina refinery with an initial capacity of 1.8 million mtpy; an aluminium smelter with



- 35 -

##### Table of Contents

INFORMATION ON THE COMPANY







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 is expected to produce sheet, end and tab stock for the
manufacture of aluminium cans, as well as other products to serve the automotive, construction, and other industries.

The
refinery, smelter and rolling mill are located within Ras Al Khair industrial zone on the east coast of the Kingdom of Saudi Arabia. First hot metal from the smelter was produced on December 12, 2012. The preliminary start-up of the rolling
mill occurred at the end of 2013 and rolling mill production is anticipated to start during the second quarter of 2014. First production from the mine and refinery is expected in the fourth quarter of 2014.

AWAC will have a 25.1% economic interest in the mine and refinery and no interest in the aluminium smelter and rolling mill. The joint
venture will utilize project financing for approximately 60% of the required capital. In 2011 the Maaden Bauxite and Alumina Company signed a US$1 billion financing agreement with the Public Investment Fund and further financing agreements for
the mine and refinery project totaling US$991.5 million with local and international banks and financial institutions. The refinery has been designed to facilitate growth through creep and expansion.

Alcoas long term debt is currently rated BBB  with negative outlook by Standard & Poors Rating Services and
BBB  with negative outlook by Fitch Ratings. Moodys Investors Services downgraded Alcoas long term debt to Ba1 with stable outlook from Baa3 on May 29, 2013.

Under the project financings for the joint venture project in the Kingdom of Saudi Arabia, a downgrade of Alcoas credit ratings
below investment grade by at least two rating agencies would require Alumina Limited to provide a letter of credit or fund an escrow account for a portion or all of its 40% share of AWACs remaining equity commitment to the mine and refinery
joint venture.

ii) Shipping

Alcoa Steamship Inc.

AWAC owns and operates a shipping operation
(Alcoa Steamship) that provides transportation services to AWACs alumina business and to other parties, including Alcoa. Operating both owned and chartered vessels, the shipping business transports dry and liquid bulk cargoes, including
bauxite, alumina, caustic soda, fuel oil, petroleum coke and limestone.

AWAC owns three combination carriers, which can carry
primarily alumina, caustic soda and bauxite for the facilities. They are also back filled with general cargo from the United States Gulf Coast to Suriname. AWAC operates one smaller vessel in the Caribbean to shuttle alumina from Suriname to the
bulk loading terminal in Trinidad. AWAC also charters ocean carriers for the transport of bauxite, alumina, caustic soda, petroleum coke and limestone (for both AWAC and Alcoa) between its various global operations. AWAC also operates two dry bulk
vessels which transport alumina from the West Australian refineries to the Victorian smelters.

iii) Markets and
Competition

The alumina market is competitive, with many active suppliers and commodity traders. In recent times there has
been significant growth in refining in China, India and Brazil. The majority of product is sold in the form of smelter grade alumina with about 5% to 10% of total alumina production being used to make alumina based chemicals.

Alumina supply is critical to aluminium smelter operations and, in addition to price, reliability of supply, quality and delivery are key
factors in contract negotiations. Contracts for smelter grade alumina are usually for a multi-year time period, although pricing mechanisms have changed over time from primarily long term contracts with fixed pricing and terms to shorter term
contracts with some annual price renegotiations.

A significant development occurred in the pricing structure for alumina
during 2010. Traditionally most alumina outside of China has been sold to third party smelters on a medium to long term contract basis, with the price calculated as a percentage of the LME aluminium price.

In recent years however there has been a low correlation between the LME aluminium prices and alumina input costs (principally energy,
caustic soda and bauxite/freight).



- 36 -



---

##### Table of Contents

INFORMATION ON THE COMPANY







The alumina input costs have had different drivers to those of aluminium and disparities
between those costs has led to the way alumina has been traditionally priced becoming disconnected to the underlying economics of producing and selling alumina. In 2010 a number of key commodity information service providers started publishing daily
and weekly alumina (spot) pricing assessments or indices.

AWAC continues to change the way its prices third party smelter
grade alumina for its customers by moving toward spot or alumina index pricing that de-links the price for alumina from the aluminium price, to better reflect aluminas distinct supply and demand and other fundamentals. In 2013, approximately
54% of AWAC smelter grade alumina shipments were based on spot/index prices, compared to 35% for 2012, and it is expected that 65% of AWAC third party smelter grade alumina shipments will be based on spot or alumina index prices during 2014.

Markets

AWACs largest customer for its smelter grade alumina production is Alcoas primary smelting group which in 2013 accounted for approximately 37% of AWAC total sales. Remaining sales are usually
a variety of contract types to customers all over the world which are priced by reference to the published LME aluminium price and spot market pricing. An increasing percentage of production is being sold into the spot alumina market.

AWAC entered into a new five-year alumina supply contract with Alcoa in 2010 which expires at the end of 2015. The price paid for the
AWAC production by Alcoa smelters is currently determined by applying the weighted average of:



| |  |  | the prices received by AWAC from the sale of alumina to unrelated third parties; and
| | - |  | ------------------------------------------------------------------------------------



| |  |  | the contract price paid by the Alumax smelters set under the contracts negotiated when the Alumax smelters were still unrelated to Alcoa.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------

Employees

At the end of 2013, AWAC had 7,727 employees in its operations compared with 7,931 in 2012 and 7,880 in 2011. The number of employees was:



|                  |  |      |       |  |      |  |       |      |  |  |       |

|Alumina           |  |      | 6,841 |  |      |  | 7,042 |      |  |  | 6,931 | 
|Aluminium         |  |      | 876   |  |      |  | 877   |      |  |  | 937   | 
|Chemicals & Other |  |      | 10    |  |      |  | 12    |      |  |  | 12    | 

At the end of 2013, Alumina Limited had 13 employees compared with 12 in 2012 and 11 in 2011.

Regulatory and Environmental

The possibility exists that new legislation or regulations may be adopted that may materially adversely affect AWACs mining and processing operations or AWACs cost structure. New legislation
or regulations, or more stringent interpretations or enforcement of existing laws and regulations, may also require AWACs customers to change operations or incur increased costs. These factors and legislation, if enacted, could have a material
adverse effect on AWACs, and hence Alumina Limiteds, financial condition and results of operations.

Governments
extensively regulate AWACs mining and processing operations. National, state and local authorities in Australia and other countries in which AWAC operates regulate the mining and minerals processing industries with respect to matters such as
employee health and safety, permitting and licensing requirements and many aspects of environmental compliance including; air emissions and waste management, plant and wildlife protection, reclamation and restoration of mining properties after
mining is completed, and the effects that mining has on surface and groundwater quality and availability. Numerous governmental permits and approvals and leases are required for AWACs mining and processing operations. AWAC is required to
prepare and present to national, state or local authoritys data pertaining to the effect or impact that any proposed exploration or production activities may have upon the environment. The costs, liabilities and requirements associated with
these regulations may be costly and time-consuming



- 37 -

##### Table of Contents

INFORMATION ON THE COMPANY







and may delay commencement or continuation of exploration, expansion or production operations. Failure to comply with the laws regulating AWACs businesses may result in sanctions, such as
fines or orders requiring positive action by AWAC which may involve capital expenditure or the removal of licences and/or the curtailment of operations. This relates particularly to environmental regulations.

AWAC has obligations under various laws, licences and permits for the rehabilitation (including remediation and/or restoration) of land
used in bauxite mining, alumina refining, aluminium smelting and related activities. AWAC and Alumina Limited recognise and provide for additional amounts for certain AWAC Asset Retirement Obligations.

Energy is a significant input in a number of AWACs operations. AWAC uses significant quantities of electricity, oil, gas and
coal in its operations and is an emitter of greenhouse gases. A number of governments or governmental bodies have introduced or are proposing significant regulatory changes in response to the potential impacts of climate change. Further information
on this and other regulatory risks is set-out in Item 3D Risk Factors-Regulatory change by governments in response to greenhouse gas emissions may represent an increased cost to AWAC.

In 1994 AofA initiated epidemiological studies of employee health  called Healthwise. The research is conducted
independently by Monash University and the University of Western Australia and tracks cancer incidence and mortality and has also examined respiratory health. To date, no conclusive evidence of an increased risk of cancer associated with any
particular type of aluminium industry work has been found in these employees. The rates of mortality overall and for the four major causes of death are lower than in the general community. The results of the respiratory health studies were
consistent with occupational asthma occurring in some smelter employees  a recognised and well controlled issue in the Australian aluminium industry. Otherwise they were unremarkable.

In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted
against Alumina Limited or AWAC, including those pertaining to environmental, product liability and safety and health matters. Whilst 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 AWACs liquidity or results of operations, and hence Alumina Limiteds, in a particular period could be materially affected by one or more of these other
matters.

The critical accounting policies relating to the
continuing operations of Alumina Limited are outlined below. These policies are deemed critical as estimates and judgments are continually evaluated based on historical experience and other factors, including expectations of future events that are
believed to be reasonable under the circumstances to ascertain the various US GAAP adjustments to translate AWACs net assets and net profit into IFRS compliant values. Alumina Limiteds significant accounting policies are described
in Note 1 to its Consolidated Financial Statements.

Impairment of assets The Alumina Group assesses at each
balance date whether there is objective evidence that the investment in associates is impaired. An impairment loss is recognized for the amount by which the assets carrying amount exceeds its recoverable amount. The recoverable amount is the
higher of an assets fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash generating units).

Deferred tax assets The Group through its equity accounted investment in AWAC has recognised deferred tax
assets and liabilities in accordance with IAS12 Income Taxes. Deferred tax assets are measured using tax rates (and laws) that have been enacted or substantially enacted by the reporting date and are expected to apply when the related
deferred asset is realised or the liability is settled. AWACs subsidiary in Brazil applied for a tax holiday related to its expanded mining and refining operations. If approved, the tax rate for this subsidiary will decrease significantly
resulting in future tax savings over the 10-year holiday period. The net deferred tax assets of the subsidiary are required to be remeasured at the lower holiday rate for the tax losses that will be utilised during the tax holiday period. This
requires judgmental assumptions regarding the timing of future taxable profits during the tax holiday period.

AWAC

AWACs significant accounting policies are summarized in AWACs Combined Financial Statements. Some of AWACs accounting policies require the application of significant judgment by
management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty and are based on AWACs historical experience, terms of existing
contracts, managements view on trends in the alumina/aluminium industry and information from outside sources.

Management believes the following critical accounting policies, among others, affect AWACs more significant judgments and estimates
used in the preparation of AWACs Consolidated Financial Statements and could potentially impact AWACs financial results and future financial performance.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







AWACs critical accounting policies under US GAAP include those discussed
below.

Derivatives and hedging  The fair values of all outstanding derivative instruments are recorded in other
current and non-current assets and liabilities in the combined balance sheet. The ineffective portions are recorded in revenues or other income or expense in the current period. Under IFRS, realized or unrealized gains and losses on the hedging
contracts are deferred in other assets or other liabilities until the underlying transaction takes place. When the underlying transaction takes place gains, losses, premiums and discounts are taken to the profit and loss as part of sales revenue or
costs. If a contract ceases to qualify as an effective hedge then all premiums, discounts, gains and losses are recognized in the profit and loss.

Inventory valuation AWAC inventories are carried at the lower of cost or market, with cost for a portion of U.S. inventories determined under the last-in, first-out (LIFO) method. The cost
of other inventories is principally determined under the average-cost method. The LIFO method is not allowed under IFRS. Alumina Limited adopts the first in, first out (FIFO) valuation methodology in the IFRS financial statements.

Foreign currency The local currency is the functional currency for AWACs significant operations outside the U.S.,
except in Jamaica and Suriname, which use the U.S. dollar for their functional currency. The determination of the functional currency in these countries is based on the appropriate economic and management indicators.

Environmental Expenditure  Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures
relating to existing conditions caused by past operations, and which do not contribute to future revenues, are expensed. Liabilities are recorded when remedial efforts are probable and the costs 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 AWAC has reason to believe such parties will not fully pay their proportional 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.

Goodwill and other intangibles Goodwill is not amortized, instead, it is tested for impairment annually (as of
October 31) or more frequently if indicators of impairment exist or if a decision is made to sell 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 values 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. AWAC has two reporting units: Alumina and Primary Metals. 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 (more 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, 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 proceed directly to the two-step quantitative impairment test. 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. Under the two-step quantitative



- 41 -

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







impairment test, the evaluation of impairment involves comparing the current fair value of a reporting unit to its carrying value, including goodwill. AWAC 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, costs to produce, 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 members equity.

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, AWAC recorded a goodwill impairment of $30.2 million, which is recorded in Restructuring and other charges in the Combined Statements of (Loss)
Income. As a result of the goodwill impairment, there is no goodwill remaining for the Primary Metals reporting unit.

The
impairment of Primary Metals goodwill results 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.

Asset Retirement
Obligations  AWAC recognizes asset retirement obligations (AROs) related to legal obligations associated with the normal operation of AWACs bauxite mining, alumina refining and aluminium smelting facilities. These AROs consist
primarily of costs associated with spent pot lining disposal, closure of bauxite residue areas, mine reclamation, and landfill closure. AWAC also recognizes AROs for any significant lease restoration obligation, if required by a lease agreement. 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, AWAC capitalizes asset retirement costs by increasing the carrying amount of
the related long-lived assets, and depreciating these assets over the remaining useful life.

Mineral Rights 
AWAC recognizes mineral rights upon specific acquisitions of land that include such underlying rights, primarily in Jamaica. 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 costs 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, plant and equipment on the Combined Balance Sheet.

Deferred Mining
Costs  AWAC 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

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







further define the grade and quality of the known bauxite, and overburden removal costs. These costs relate to sections of the related mines where AWAC 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 the level of reserves. Deferred mining costs are included in Other
noncurrent assets on the Combined Balance Sheet.

Stock-Based Compensation Certain employees of AWAC receive
stock-based awards under Alcoas stock incentive plans and AWAC records an expense for these plans. AWAC 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. 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, annual forfeiture rate and exercise behaviour. These assumptions may differ significantly between grant dates because of changes in the actual results of these inputs over time. Most plan participants can
choose whether to receive their award in the form of stock options, restricted share units, or a combination of both. This choice is made before the grant is issued and is irrevocable.

General Factors

Alumina Limiteds financial and operational performance and prospects are influenced by a number of factors which predominantly result from its 40% interest in AWAC, the level of debt carried by
Alumina Limited, and equity raisings.

As at December 31, 2013, Alumina Limiteds debt was incurred through several
facilities:



| |  |  | A bilateral bank facility of $50.0 million with a maturity date of November 2016. This facility has since been cancelled.
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | A $296 million facility from the Brazilian National Development Bank (BNDES). This funding is provided in US$ and Brazilian Reais and amortizes from
December 2010 to July 2016. At December 31, 2013, the outstanding balance of the facility was $129 million.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The amount of interest charged on these debt facilities will impact the profitability of Alumina Limited. The interest amount incurred will depend on the amount of debt carried and interest rates.

During 2013:



| |  |  | Facilities totaling US$695 million were cancelled. A further facility of US$50 million was cancelled in January 2014.
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | A new US$300 million syndicated bank facility with tranches of two and four years was established in December 2013. The new syndicated facility was
fully committed as at December 31, 2013 and became available to draw funds on January 30, 2014 following satisfaction of all conditions precedent.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Alumina Limiteds 40% share of AWACs continuing operations during the three year period to December 31, 2013 was characterized by a focus upon:



| |  |  | continuing to match AWAC production to market conditions
| | - |  | --------------------------------------------------------



| |  |  | change to alumina sales pricing structure whereby a greater portion of sales are at alumina price indices or spot prices
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | investment in new mine and refinery in the Kingdom of Saudi Arabia.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







The following is a discussion of the key factors which affect AWAC and Aluminas
business and financial performance.

Commodity prices

AWAC sells products which are commodities and its financial performance is significantly influenced by the prices it obtains for these
products and, in particular, the LME price of primary aluminium and alumina indices. The price of a commodity is generally determined by, or linked to, the price for the product in question in the world markets. World commodity prices are subject to
changes in supply and demand, and characterized by significant fluctuations. The volatility of commodity prices, even where production levels and costs remain constant, means that the sales revenues (and in the absence of mitigating factors, profit)
generated by sales of AWAC products varies.

Fluctuations in the A$/US$ Exchange Rate

The world commodity prices for the products AWAC sells are denominated in, or linked to, US$. By contrast, a significant portion of
AWACs costs are denominated in A$. As a consequence, fluctuations in the rate of exchange between the US$ and A$ may have an effect on the financial results of Alumina Limited. Appreciation of the US$ relative to the A$ reduces the value of
unhedged costs in A$ as compared to US$ revenues and has a positive impact on profit. A depreciation in the US$ as compared to the A$ decreases the value of unhedged costs in A$ as compared to US$ revenues and exerts negative pressure on profit.
AofA contributes the majority of AWACs earnings. However, for those refineries outside Australia, a portion of their costs are denominated in the local currency and movements in those currencies relative to the US$ will also have an effect on
the financial results of Alumina Limited.

Production Costs

Changes in AWACs costs have a major impact on its profitability. AWACs mining, refining and smelting operations are subject to
conditions beyond its or Alumina Limiteds control that can delay deliveries or increase costs for varying lengths of time.

The cash cost per tonne of alumina produced declined continuously during 2013, resulting in 2013 average cash cost per tonne decreasing by 5.5% from the 2012 average. This decrease reflects productivity
initiatives and efforts to create more stable operating conditions to avoid costs associated with production disruptions.

Earnings before interest, tax, depreciation and amortization margin was $45 per tonne of alumina produced in 2013, higher than in 2012 by
$14 per tonne. Increased margins were a result of lower production costs and higher shipments.

Certain costs are also
affected by government imposts and regulations in countries in which AWAC operates. AWACs costs depend upon efficient design and construction of mining, refining and smelting facilities and competent operation of those facilities.

Changes to Sales Agreements

Long term supply agreements are in place for varying volumes and tenors. As such, AWACs revenue from existing sales agreements depends on the outcome of periodic renegotiation of these agreements.
The modification or termination of a substantial portion of AWACs sales agreements could materially affect its results and financial performance. An increasing proportion of AWACs alumina production is sold on a short term or spot basis.
Changes to the volumes that are able to be sold on a short term or spot basis and the pricing for such sales may affect AWACs sales revenue.

The traditional alumina pricing methodology was to link the price of alumina as a percentage of the aluminium price. The linkage methodology in recent years has not recognized that alumina industry
fundamentals are different from those of aluminium.

In 2010 a significant development occurred in the pricing structure for
alumina. Several independent pricing indices were developed for alumina based on spot sales.

A more extensive description of
the change in pricing and its implications for Alumina Limited is covered under Markets and Competition on page 37.

Regulatory Environment

The costs, liabilities and requirements associated with regulations may be costly and time-consuming and may delay commencement or continuation of exploration, expansion or production operations. Of
particular importance in



- 44 -

##### Table of Contents

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







Australia is the impact of environmental regulations and carbon tax/greenhouse gas regulations and renewable energy. New legislation or regulations may be adopted that may materially adversely
affect AWACs operations or cost structure.

Political Risk

AWAC operates in a number of countries. Political activities in these countries may be destabilizing and disruptive to AWACs
operations. The impact of any such disruption could range from a minor increase in operating costs or taxes to a materially adverse impact, such as the closure of an operation.

Development of Projects and Production Performance

AWACs ability to sustain or increase its current level of production, and therefore its (and hence Alumina Limiteds) profits in the medium to long-term, is partially dependent on the
development of new projects and on the expansion/curtailment of existing operations.

On February 18, 2014, Alcoa Inc
announced the permanent closure of AWACs Point Henry aluminium smelter. Total AWAC restructuring related charges associated with the closure of the Point Henry smelter are expected to be approximately $250 million after tax. AWACs cash
costs after tax during 2014 in respect of the closure are expected to total approximately $50 million. Further after tax cash costs of approximately $70 million are expected to be incurred by AWAC in later years.

The Maaden joint venture in Saudi Arabia (1.8 million tonnes of which AWAC has 25.1%) is forecast to produce alumina in the fourth
quarter of 2014 and is expected to be a first quartile producer and bring AWAC down the world refining cash cost curve.

By
2015, AWAC is expected to start receiving the operating cost benefits of a conversion of the San Ciprian refinery from oil to gas.

Alumina Limiteds Cash Flows

Alumina Limiteds cash flows are
generated primarily from distributions made by AWAC, by way of dividends or capital return. The Strategic Council, which is 60% controlled by Alcoas nominees, determines the timing and magnitude of AWAC dividends and capital returns, subject
to the relevant provisions of the AWAC Agreements. Alumina Limited cannot unilaterally determine AWACs dividend policy or the quantum or timing of dividends to be paid by AWAC. AWAC must distribute by way of dividends, in each financial year,
at least 30% of the net income of the prior year of each of the entities comprising AWAC, unless the Strategic Council agrees by a super majority vote to pay a smaller dividend.

During 2006 the AWAC joint partners entered into a new funding agreement under which future capital expenditures are to be funded by the
partners contributing directly to cash calls issued by the relevant AWAC entity. When such cash calls are issued, additional dividends equal to the amount of the cash call will, subject only to availability of cash and earnings, be paid by AWAC
entities to the partners. During 2010, the funding agreement was extended on the basis that two years notice is required to terminate the agreement.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







As presented in Note 1 of Alumina Limiteds consolidated financial statements, the adoption of
revised IAS 19 Employee Benefits resulted in the restatement of comparative information. The performance analysis below reflects restated financial information.

2013 Performance Compared to 2012

Overview  Alumina
Limited

Alumina Limiteds consolidated net profit after tax from continuing operations was $0.5 million for the
year ended December 31, 2013 compared with a loss of $55.6 million for the year ended December 31, 2012. This increase in 2013 compared to 2012 was due to the following:

Share of net loss of associates using the equity method

Share of net loss of associates increased by $89.9 million to a loss of $97.4 million. Refer to Overview-AWAC on page 48 for explanation on the increase.

The AWAC results are adjusted for differences between US GAAP and IFRS prior to incorporation into the Alumina Limited results. These
adjustments are non-cash book entries.

The main adjustments for the 2013 year are:



| |  |  | recognition of $2.1 million deferred tax expense in Brazil
| | - |  | ----------------------------------------------------------



| |  |  | recognition of $7.7 million after tax for asset retirement obligations
| | - |  | ----------------------------------------------------------------------



| |  |  | recognition of $16.6 million credit after tax for movements in embedded derivatives
| | - |  | -----------------------------------------------------------------------------------



| |  |  | reversal of $30.2 million of goodwill impairment relating to pre-IFRS acquisition of Eastern Aluminium Ltd.
| | - |  | -----------------------------------------------------------------------------------------------------------

General and administrative expenses

General and administrative expenses decreased by $1.8 million (9%) to $17.2 million. Most of Alumina Limiteds general and administrative expenses are incurred in Australian dollars. The
decrease over 2012 is primarily due to lower expenditure, rather than currency fluctuations.

Other Income/expenses

A net gain of $3.0 million on Brazilian Reais financial instruments was recognized in 2013 compared to a $0.6 million gain
in 2012. Alumina Limited also recognized $137.1 million as the allocation of the Aluminium Bahrain BSC settlement in 2013 (Refer to Notes 5 and 12 of the Consolidated financial Statements for further details).

Borrowing Costs

Borrowing costs decreased by $4.1 million (14%) to $25.3 million due to lower average net borrowings offset by the write-off of unamortized establishment fees relating to the bank facilities that
were terminated during 2013.

Income tax expense

In 2013, Alumina Limited did not incur any income tax expense compared to a charge of $0.4 million in 2012. The majority of the income of
Alumina Limited is the equity accounted share of profits which is not assessable for tax.

Cash Flows

Alumina Limiteds net cash inflow from operating activities for 2013 was $67.5 million, compared to $48.6 million in 2012,
an increase of 39%. Higher dividends and distributions from associates, lower general and administrative expenses and lower borrowing costs drove higher cash from operating activities.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







Alumina Limiteds cash outflow relating to investing activities from continuing
operations for 2013 was $9.0 million, compared to $171.0 million in 2012, a decrease of 95%. The reduction in cash outflows from investing activities in 2013 was due to lower investments in AWAC. Net payments for investments in associates related to
the Maaden joint venture in 2013, whilst during 2012 expenditure was related to the Maaden joint venture, the Juruti mine in Brazil and working capital contributions for AWAC entities.

Alumina Limiteds net cash outflow from financing activities for continuing operations was $45.4 million for 2013, compared to
an inflow of $114.3 million in 2012. Key changes were:



| |  |  | Proceeds for the share issue raised $467.2 million in 2013, compared with nil in 2012.
| | - |  | --------------------------------------------------------------------------------------



| |  |  | No cash dividends were paid in 2013 compared with $73.2 million in 2012.
| | - |  | ------------------------------------------------------------------------



| |  |  | Drawdowns of $70.0 million in 2013, offset by debt repayments of $581.4 million, compared to drawdowns of $240.0 million offset by debt repayments of
$52.5 million in 2012.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Net Assets

Alumina Limiteds net assets increased in 2013 by $164.9 million (6%) to $2,793.4 million primarily because:



| |  |  | Investment in associates decreased by $497.2 million to $2,798.9 million. The decrease was attributable to the impact of the higher Australian dollar
and Brazilian Reais amounting to $372.2 million and a surplus of dividends received over equity share in profits of $204.7 million offset by additional funding capitalization in AWAC entities amounting to a net of $9.0 million.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash increased by $13.9 million to $24.0 million, for the reasons noted above in the discussion on Alumina Limiteds cashflow from operating,
investing and financing activities.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest-bearing liabilities decreased by $515.3 million to $159.2 million. During 2013 Alumina Limited borrowed additional amounts in US$ amounting to
$70.0 million and repaid debt amounting to $581.5 million, primarily from the proceeds from the share issue which raised $467.2 million.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other assets increased by $135.9 million, mainly as a result of the allocation of the Aluminum Bahrain BSC (Alba) settlement (refer to Notes 5 and 12
of Alumina Limiteds Consolidated Financial Statements.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Equity

Alumina Limiteds equity increased by $164.9 million (6%) in 2013 to $2,793.4 million. The key items include:



| |  |  | $373.1 million net exchange loss recognized in equity in 2013
| | - |  | -------------------------------------------------------------



| |  |  | $0.5 million net profit for 2013
| | - |  | --------------------------------



| |  |  | $465.9 million from equity contributions received in 2013.

AWACs 2013 sales revenue of $5,884.6 million (including sales to parties related to AWAC of
$2,113.8 million) was 1% higher than 2012 sales revenue of $5,815.3 million (including sales to related parties of $2,170.3 million). Increased shipments were the principal reason for the revenue increase. Average realized alumina prices were
marginally lower than 2012. Revenue per tonne from smelter grade alumina sales priced by reference to indices and spot continued to be higher than the legacy LME-linked products. The average three-month LME aluminium price, determined on a two-month
lag basis, declined by 6% compared to 2012 whereas average alumina price index FOB Australia (one-month lag) increased by 3%.

AWACs alumina production was 15.8 million tonnes (2012: 15.6 million tonnes) up 1.3% from 2012. The Point Comfort
refinery contributed most of this growth reflecting its improved stability.

Aluminium production from AWACs two
aluminium smelters was 354 thousand tonnes of aluminium, compared to 2012 production of 358 thousand tonnes, the decrease was largely due to the Anglesea power station maintenance.

AWACs net loss of $248.7 million in 2013 represented an increase of 171% compared to a net loss of
$91.9 million in 2012.

The $384 million pre-tax charge in relation to the Alba legal matter was the significant item which
affected the AWAC result.

Increased margins per tonne of alumina produced were higher in 2013 compared with 2012 as a result
of lower production costs and higher shipments. The cash cost per tonne of alumina produced declined continuously during 2013, resulting in 2013 average cash cost per tonne decreasing by 5.5% from the 2012 average. The decrease reflects productivity
initiative and efforts to create more stable operating conditions to avoid costs associated with production disruptions. In addition, the Australian dollar and Brazilian Reais weakened against the US dollar, providing significant currency benefits.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







2012 Performance Compared to 2011

Overview  Alumina Limited

Alumina Limiteds consolidated net loss after tax from continuing operations was $55.6 million for the year ended December 31, 2012 compared with a profit of $182.5 million for the year
ended December 31, 2011. This decrease in 2012 compared to 2011 was due to the following:

Share of net profits of
associates using the equity method

Share of net profit of associates decreased by $236.5 million (103%) to a loss of
$7.5 million. Refer to Overview-AWAC below for explanation on the increase.

The AWAC results are adjusted for differences
between US GAAP and IFRS prior to incorporation into the Alumina Limited results. These adjustments are non-cash book entries.

The main adjustments for the 2012 year are:



| |  |  | recognition of $69 million deferred tax credit in Brazil
| | - |  | --------------------------------------------------------



| |  |  | recognition of $8 million debit after tax for defined benefit pensions
| | - |  | ----------------------------------------------------------------------



| |  |  | recognition of $3 million credit after tax for movements in embedded derivatives.
| | - |  | ---------------------------------------------------------------------------------

General and administrative expenses

General and administrative expenses increased by $1.7 million (10%) to $19.0 million. Most of Alumina Limiteds general and administrative expenses are incurred in Australian dollars. The
increase over 2011 reflects one-off expenses that exceeded other expense reductions.

Other Income/expenses

A net gain of $0.6 million on Brazilian Reais financial instruments was recognized in 2012 compared to a $0.1 million gain in 2011.

Borrowing Costs

Borrowing costs increased by $0.9 million (3%) to $29.4 million due to the overall increase in net debt position partially offset by lower commitment and upfront fees.

Income tax expense

In 2012, Alumina Limited incurred an income tax charge of $0.4 million compared to a charge of $1.0 million in 2011. The majority of the income of Alumina Limited is the equity accounted share of profits
which is not assessable for tax.

Cash Flows

Alumina Limiteds net cash inflow from operating activities for 2012 was $48.6 million, compared to $196.1 million in 2011, a decrease of 75%. Lower dividends and distributions from
associates, higher general and administrative expenses and higher borrowing costs drove lower cash from operating activities.

Alumina Limiteds cash outflow relating to investing activities from continuing operations for 2012 was $171.0 million, compared to
$149.3 million in 2011, an increase of 14%. This increase in cash outflows from investing activities in 2012 was due to further investments in the AWACs refineries. Alumina Limited did not receive any proceeds from return of invested capital
during 2012, compared to $17.3 million received during 2011.

Alumina Limiteds net cash inflow from financing activities
for continuing operations was $114.3 million for 2012, compared to an outflow of $139.2 million in 2011. Key changes were:



| |  |  | There were no payments for the repurchase of the convertible bond in 2012 compared to $167.6 million during 2011.
| | - |  | -----------------------------------------------------------------------------------------------------------------

| |  |  | Drawdowns of $240.0 million in 2012, offset by debt repayments of $52.5 million, compared to drawdowns of $285 million offset by debt repayments of
$86.0 million in 2011.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Net Assets

Alumina Limiteds net assets decreased in 2012 by $225.5 million (8%) to $2,628.5 million primarily because:



| |  |  | Investment in associates decreased by $28.7 million to $3,296.1 million. The decrease was attributable to the higher Australian dollar and Brazilian
Reais amounting to $89.7 million and by surplus of dividends received over equity share in profits of $102.6 million offset by additional funding capitalization in AWAC entities amounting to $171.0 million.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash decreased by $8.9 million to $10.1 million, for the reasons noted above in the discussion on Alumina Limiteds cash flow from operating,
investing and financing activities.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest-bearing liabilities increased by $183.9 million to $674.5 million. During 2012 Alumina Limited borrowed additional amounts in US$ amounting to
$240.0 million and repaid debt amounting to $52.5 million.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Equity

Alumina Limiteds equity decreased by $225.5 million (8%) in 2012 to $2,628.5 million. The key items include:



| |  |  | $89.9 million net exchange loss recognized in equity in 2012
| | - |  | ------------------------------------------------------------



| |  |  | $55.6 million of net losses for 2012

AWACs 2012 sales revenue of $5,815.3 million (including sales to parties related to AWAC of
$2,170.3 million) was 13% lower than 2011 sales revenue of $6,667.0 million (including sales to related parties of $2,522.4 million). Alumina revenue declined by 13% compared to 2011. Price movements were the principal reason for the revenue
decrease. Realized alumina prices decreased 13% compared to 2011. LME-linked contract prices declined by a greater extent than contracts based on spot or alumina index.

AWACs alumina production was 15.6 million tonnes (2011: 15.7 million tonnes) down 0.6% from 2011. The reduction largely resulted from planned reduced annual production of approximately
390 thousand metric tonnes in the higher unit cost refineries, offset by production creep in the lower unit cost Australian refineries that continued to operate at near or above nameplate capacity during 2012. AWACs nameplate production
capacity is 17.2 million tonnes per annum.

Aluminium production from AWACs two aluminium smelters was
358 thousand tonnes of aluminium, compared to 2011 production of 357 thousand tonnes.

AWACs net loss of $91.9 million in 2012 represented a decrease of 120% compared to a net profit of
$469.7 in 2011.

Price movements were the principal reason for the revenue decrease. The 2012 cash cost of alumina per tonne
increased by 1% over 2011. This increase mainly reflected a rise in the cost of caustic soda, partially offset by a reduction in other costs.

Lower margins were achieved in 2012 compared with 2011 predominantly as a result of weaker realized prices and higher input costs partially offset by productivity improvements.

Net cash inflow from financing operations increased to $258.7 million, compared to a $441.0 million outflow in 2011. Key changes were:



| |  |  | a decrease in level of dividends paid and return of capital to partners of $403.4 million to $238.5 million in 2012 compared to $641.9 million in 2011

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







B. Liquidity and Capital Resources

The ability of Alumina Limited and its subsidiaries to generate cash internally is influenced by the following major factors:



| |  |  | the level of world commodity prices and exchange rates to which AWACs revenue is substantially exposed
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | the level of sales and cost performance by AWAC
| | - |  | -----------------------------------------------



| |  |  | the amount of dividends received from AWAC
| | - |  | ------------------------------------------



| |  |  | the amount of capital expenditure required by AWAC to develop new projects or maintain or expand existing operations (refer to Section 4.B).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

These factors are expected to continue to influence Alumina Limiteds liquidity and capital resources
in future years.

In addition, because Alumina Limited is a holding company that does not conduct any material operating
businesses, its ability to pay dividends and meet other obligations is dependent almost entirely on, and is limited by, the amount of dividends received from its subsidiaries, associates and investments.

The AWAC Agreements state a preference to finance its activities from cash flow of the affiliated operating entities and from borrowings.
The AWAC Agreements limit leveraging of individual AWAC entities to a maximum ratio of debt (net of cash) to total capital of 30% (a super majority vote of the Strategic Council is required to exceed this limit). Should the aggregate annual capital
budget of AWAC still require, after utilising available cash flow, an additional contribution from Alumina Limited and Alcoa, then the parties contribute their proportionate share thereof subject to the provisions set out in the AWAC Agreements.
AWAC may make an annual capital request of up to $1 billion following a decision by a majority vote of the Strategic Council, of which Alcoa Inc has majority voting power.

In 2006, Alumina Limited and Alcoa entered into new funding arrangements to provide the AWAC partners with additional dividends from AofA for funding AWACs capital projects. During 2010, the funding
arrangements were extended on the basis that two years notice is now required to terminate the arrangements.

It is expected
that Alumina Limiteds existing balance of franking credits and the funding arrangements between Alumina Limited and Alcoa will enable Alumina Limited to fully frank dividends that are declared.

Dividends received in 2009, 2010, 2011, 2012 and 2013 have partially funded Alumina Limiteds investment in AWACs growth
projects. Alumina Limiteds share of additional funding requirements was met by increased borrowings and the 2008 and 2009 rights issues, and the 2013 share placement.

No dividends were paid during 2013. Dividends of $73.2 million were paid during 2012. Alumina Limited has continued the suspension of the Companys Dividend Reinvestment Plan.

Dividends and distributions received from AWAC and drawings under Alumina Limiteds committed debt facilities funded the
Companys financing requirements in 2013 and 2012 including AWACs investments in the completion of growth projects in Brazil and sustaining capital projects.

On August 29, 2012, Standard & Poors (S&P) lowered Alumina Limiteds credit rating to BBB  Outlook Stable from BBB Outlook Negative due to their expectation of weak
alumina and aluminium market dynamics. On February 22, 2013, S&P reconfirmed that rating.

Funds generated from
Alumina Limiteds continuing operating activities were $67.5 million for the year ended December 31, 2013, compared with $48.6 million in 2012. This increase was a result of higher dividends from associates, lower corporate costs and lower
amounts of interest paid on borrowings.

Working capital was negative $13.6 million at December 31, 2013, compared to
working capital of negative $44.7 million at December 31, 2012. The decrease was due to an increase in cash balances and $20.0 million due in relation to the allocation of the Alba settlement (Refer Note 5 to the Consolidated Financial
Statements). Cash balances at December 31, 2013 were $24.0 million compared to $10.1 million at December 31, 2012. Alumina Limiteds net

OPERATING AND FINANCIAL REVIEW AND PROSPECTS







debt decreased during the year from $664.4 million to $135.2 million primarily due to the issuing of 366,029,428 fully paid ordinary shares to CITIC Resources Australia Pty Ltd and Bestbuy
Overseas Co Ltd, which raised approximately $467 million. Alumina Limiteds liabilities can be met using available cash and undrawn committed facilities whose maturities extend to 2017.

Gross debt drawn down under Alumina Limiteds various debt facilities was $159.2 million at December 31, 2013 compared to total
gross borrowings of $674.5 million at December 31, 2012. The decrease in debt at year end is mainly attributable to the share placement mentioned above.

The maturity of debt is outlined in Note 2 and 15 to the Consolidated Financial Statements. Alumina Limiteds funding facilities at December 31, 2013 include a bilateral bank facility and a
development bank loan. The bilateral bank facility is available in US dollars. The development bank loan is fully drawn in US dollars and Brazilian Reais and amortises at approximately $51 million per annum.

In addition to the facilities above, in December 2013, Alumina Limited established a new US$300 million syndicated bank facility with
tranches of two and four years and cancelled several bilateral and syndicated bank facilities, which were surplus to requirements. The new syndicated facility was fully committed as at December 31, 2013 and became available to draw funds on
January 30, 2014 following satisfaction of all conditions precedent.

The key funding principles inherent in Alumina
Limiteds treasury policies are:



| |  |  | conservative levels of debt should be maintained over the longer term to ensure that the Companys activities and growth are not debt constrained.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | debt should be sourced at the most competitive price available, although this needs to be balanced against having a diversity of sources and a managed
maturity profile.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | debt tenor and currency should reflect asset life, currency exposure and overall level of debt. A core amount of long-term debt would generally be
retained with the balance in short-term and medium-term debt due to its lower cost and repayment flexibility.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | project finance should be utilised where warranted by risk management considerations (country or project specific).
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | where foreign currency assets are acquired, raising debt in that currency should be considered to achieve a balance sheet hedge and reduce foreign
exchange translation exposures.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | interest costs should be minimised.
| | - |  | -----------------------------------

Investment expenditure was $12.0 million for the year ended December 31, 2013 and $171.0 million for the year ended December 31, 2012. The 2013 expenditures were in the form of equity
contributions for the Maaden joint venture whilst the 2012 expenditure was to fund AWACs expansion projects in Brazil, equity contributions for the Maaden joint venture and contributions for working capital.

Change in Functional Currency for Financial Reporting

An entitys functional currency is the currency of the primary economic environment in which the entity operates. With Alumina Limiteds investment program in Brazil almost completed, greater
production and cash flows to shareholders are expected from these assets in future. Most dividends received by the Alumina Group are in US dollars. Consequently in February 2010 the Alumina Limited Board recognised the change in the balance of
factors that are assessed to determine Alumina Limiteds functional currency, and changed Alumina Limiteds functional currency to US dollars, effective January 1, 2010.

In February
2003, a share plan for Alumina Limited employees was introduced. The plan provides rewards for employees based on Alumina Limiteds performance against two peer indices. Actual rewards depend upon the performance of Alumina Limited exceeding
the performance of a percentage of companies in an index on a total shareholder return basis. From December 2002, short term incentives are payable to management according to key performance indicators applicable to the individual and Alumina
Limited.

Alumina Limiteds current full-time employees are members of a fund of their choice. Contributions are funded
at the Superannuation Guarantee Contributions rate, currently 9.25% of an employees fixed remuneration.

C. Board
Practices

The Board, working with senior management, is responsible to shareholders for overall management of Alumina
Limited, its business performance and for formulating and establishing its strategic goals. It approves company strategy and direction, strategic goals, operating budgets and business performance targets. The Board ensures that appropriate policies,
procedures and systems are in place to manage risk, optimise business performance, maintain high standards of ethical behaviour and legal compliance and protect the interests of shareholders.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES







Relevant experience, diverse perspectives and complementary business skills are sought
when appointing new directors. The Board comprises a non-executive chairman, four other non-executive directors and one executive director. A balance between independent business experience, diversity and industry knowledge is sought. To assist in
the discharge of their duties, Directors have the right to seek independent professional advice collectively and individually.

Board visits are regularly conducted to AWAC operational sites to review business performance, review operating processes and meet with
management.

A director may not hold office for a continuous period in excess of three years or past the third Annual General
Meeting following the directors appointment, whichever is the longer, without submitting for election or re-election. If no director would otherwise be required to submit for election or re-election, the director to retire at the Annual
General Meeting is the director who has been longest in office since their last election.

Eligible retiring directors may
offer themselves for re-election by the shareholders. The Companys Nomination Committee Charter provides that Non-Executive Directors shall retire after nine years of continuous service as a Non-Executive Director (or immediately prior to the
next succeeding annual general meeting of the Company after completion of the nine year period) unless otherwise requested to continue by the Board. A Director who is appointed a Managing Director by the Board is not required to retire by rotation.
The Directors may appoint a Director either to fill a casual vacancy or as an addition to their numbers. Such Directors hold office until the next Annual General Meeting and may be elected by the shareholders at such meeting, but are not taken into
account in determining the number of Directors who are to retire by rotation at that meeting.

Each Director has the power to
appoint any person approved by a majority of his/her co-Directors to act as an Alternate Director in his/her place, whether for a stated period or periods or until the happening of a specified event or from time to time, whenever by absence or
illness or otherwise he shall be unable to attend to his/her duties as a Director.

The Directors may from time to time
appoint one or more of their body to be a Managing Director or Managing Directors. The Directors may confer upon any Managing Director such of the powers exercisable under Alumina Limiteds Constitution by the Directors as they may elect,
without derogating from the exercise of those powers by the Directors. Peter Wasow is currently the Managing Director and Chief Executive Officer of Alumina Limited and was appointed to such position for an unspecified period.

Alumina Limiteds Constitution provides that the Directors may elect a Chairman of their meetings and determine the period for which

Annually, the Audit Committee reviews audit programmes conducted by independent external
auditors, and the internal audit function to ensure that its resources are adequate, used effectively and co-ordinated with the external auditors. It meets regularly with management, and internal and external
auditors, to ensure that adequate controls and practices are in place. The Audit Committee is responsible for the appointment and compensation of external auditors. A process has been established whereby complaints or concerns regarding financial
impropriety of employees and others can be confidentially directed to the Chairman of the Audit Committee.

The Compensation
Committee of five non-executive directors meets at least two times a year. Its role is to establish and review Alumina Limiteds remuneration plans, policies and practices, including compensation for the non-executive directors, the chief
executive officer and senior executives, and succession planning. On behalf of the Board and shareholders, the Committee considers the remuneration strategy with regard to community and industry standards and, where possible, verifies its
appropriateness using external information and advice to ensure that:

Board committee meetings are occasionally convened to address predetermined issues, when it is not
practical to organise a full Board meeting. A Board committee comprises two or more directors.

It is company policy not to
extend or maintain credit directly or indirectly or arrange for the extension of credit in the form of a personal loan to Directors and Executive Officers. The use of a corporate credit card is provided for business purposes. Personal expenses are
reimbursed to the company.

The directors, executive management and employees have adopted and abide by a Code of Conduct
(Ethics) to promote honest and ethical conduct and deter wrongdoing. In 2004, the Company approved and adopted a Whistleblower Policy providing rights to staff (including contractors and consultants) to report any perceived malpractice, impropriety,
serious unethical behaviour, legal or regulatory non-compliance or questionable accounting or audit matter. The Policy provides disclosing employees protection from any reprisal or detrimental action resulting from such disclosure.

notice. The Company may make a payment in lieu of some or all of the 12 month notice period by payment of the fixed annual reward. The base remuneration amount will be reduced pro rata to the
extent the notice period is required to be served.

If Mr Wasows employment is terminated on the basis of redundancy of
the position or by Mr Wasow giving written notice to Alumina Limited in the event of a Significant Change (which is defined to be if Alumina Limited ceases to be listed on the Australian Stock Exchange, or if there is a Significant Change to his
status and/or responsibilities which is detrimental to him), then Mr Wasow is entitled to:



| |  |  | a pro-rata payment in respect of long service leave where he has had three years or more continuous service
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | a severance payment of 2.5 weeks per completed year of service, pro-rated for completed months of service, plus an additional 13 week ex gratia payment
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in applicable cases, outplacement support.
| | - |  | ------------------------------------------

If the Board determines that his status is that of a good leaver any unvested share rights that have been granted to him in accordance with the annual grant of conditional rights and would have vested had
he remained in employment during any period for which he is paid in lieu of notice, will immediately vest and the applicable shares will be transferred to him upon termination.

If Mr Wasows employment ceases within three years from the grant date of any share rights that have been granted to him in
accordance with the annual grant of conditional rights and that have vested, and the Board determines that his status is not that of a good leaver, the shares received on vesting may be subject to immediate forfeiture.

Senior Executives

In addition to Mr Wasow, Alumina Limited has entered into a service contract with each Senior Executive (Mr Thiris, Mr Foster and Mr Wood). The contracts provide for the following retirement and
termination benefits.

If Mr Thiris, Mr Fosters or Mr Woods employment is terminated on the basis of
redundancy of their position or if they give written notice to Alumina Limited in the event of a Significant Change (which is defined to be if Alumina Limited ceases to be listed on the Australian Securities Exchange, or if there is a significant
change to their status and/or responsibilities that is detrimental to them, or if Alumina Limited decides their position is no longer required and suitable alternative employment is not offered or if they do not accept other employment), then Mr
Thiris, Mr Foster or Mr Wood (as relevant) are entitled to:



| |  |  | statutory annual leave and long service leave entitlements (with long service leave paid pro rata if there is three years or more continuous service)
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the aggregate of: a notice payment of 6 months, a severance payment of 2.5 weeks per completed year of service, and an additional severance payment of,
in the case of Mr Thiris and Mr Foster, nine weeks and in the case of Mr Wood, six weeks.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mr Thiris, Mr
Foster and Mr Wood are not entitled to the payment outlined above where the reason for Significant Change is poor performance or inability to fulfil agreed responsibilities. Mr Thiris, Mr Foster and Mr Wood are not entitled to retirement benefits
other than superannuation entitlements.

It is a requirement that the Company provides six months notice to terminate
the contract and the senior executives provide three months written notice of termination in the case of Mr Thiris and Mr Foster. The relevant notice periods are four months and two months notice respectively in the case of Mr
Wood.

In addition to any entitlements conferred on them by their service contract, each senior executive is entitled to
receive, on termination of employment, their statutory entitlements of accrued annual and long service leave, together with any superannuation benefits. None of the senior executives are entitled to receive any other additional termination payments,
other than those previously mentioned and any vesting of shares under the Employee Share Plan (ESP).

Non-Executive Director Retirement Benefits

Non-Executive Directors receive, in addition to their fees, a Superannuation Guarantee Contribution (SGC). For 2013 this was initially
nine per cent (and adjusted to 9.25 per cent in July 2013) of their fees to a maximum of A$17,122 for the Chairman and A$15,492 for other Non-Executive Directors excluding Mr Wasow and Mr Zeng. Mr Wasow as Chairman of the Audit Committee until
November 26, 2013 received an additional A$5,000 in remuneration compared to the other Non-Executive Directors and consequently his SGC was marginally higher at A$15,947. Mr Zeng joined the Board in March 2013 and received A$138,064 in total
remuneration for 2013. His SGC for 2013 was A$11,580. Non-executive Directors do not receive any other retirement benefits.

D. Employees

At December 31, 2013, Alumina Limited employed 13 people directly. All Alumina Limited employees work in the corporate office in Australia. For details of the number of AWAC employees for the periods
presented refer to Item 4.B.(iii) Employees.

E. Share Ownership

Alumina Limited does not have any option plans available to non-executive Directors, executives and senior managers (including executive
Directors) or employees (other than the ESP under which the Performance Rights are provided to Senior Executives).

Alumina
Employee Share Plan

This is a plan under which employees may be invited to participate in the grant of a conditional
entitlement to fully paid ordinary shares (a Performance Right). The Boards intention is to make offers to each employee, but this is subject to annual determination by the Board in respect of each individual for each grant. The CEO of the
Company may recommend variation in participation.

A person is only eligible to participate in the Plan and to be granted
performance rights under the Plan if they are an employee, and have satisfied the criteria that the Board decides for participation in the Plan.

For those performance rights granted prior to 2014, if less than 100% vest when tested initially at the end of a three year period, two further tests apply (over a four week period) six and 12 months
after the initial test. Any performance rights which do not vest after the second retest will lapse.

An invitation is not
transferable. An employee may only apply for performance rights in his or her name and not in the name of, or on behalf of, another person or entity. On vesting, each performance right is an unconditional entitlement to one fully paid ordinary
share.

On termination of employment of any individual, their participation in the Plan is finalised and any performance
rights not vested lapse unless the directors decide otherwise.

The value per performance right is independently calculated by
Mercer Finance and Risk Consulting using the assumptions underlying the Black-Scholes methodology to produce a Monte Carlo simulation model which allows the incorporation of the hurdles that must be met before the performance rights vest.

Set out below are the assumptions made for the performance rights granted on February 8, 2013:



|                              |  |   |      |  
|----------------------------- |  | - | ---- | -
|Share Price at Valuation date |  | $ | 1.15 |  
|Risk Free rate                |  |   | 2.8  | %
|Dividend Yield                |  |   | 3.0  | %
|Volatility                    |  |   | 41   | %

The volatility assumption is based on the actual volatility of Alumina Limiteds daily closing share
price over the three year period to the valuation date.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES







The performance criteria and testing period for each annual grant under the ESP are
determined by the Board at the time the Board determines to offer the performance rights usually in December of each year and the testing period commences at that time. The implementation of that Board determination, including the period in which
employees can consider and accept the offer, normally results in the actual granting of the performance rights in January or February.

Set out below are summaries of performance rights granted under the Plan:

Where directors have purchased or sold shares they have done so on normal commercial terms, on conditions no more favorable than those available to other shareholders.

During 2009, new legislation was introduced that altered the taxation treatment of shares acquired under Non-executive Director Share

MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS







In 2013, following a review of its policy regarding directors share ownership
requirements, the Board decided to revise the policy. Previously directors were required to hold shares equal to, or greater than, one years annual fees by the expiry of their first term as a Directors. Once maintained, that level of share
ownership was required to be maintained throughout their term of office.

Under the revised policy, Independent Directors are
required to hold shares in the Company having a value equal to 50 per cent of their base annual fees by the expiry of five years from the date of their appointment.

Provided the minimum shareholding requirement is satisfied when shares are acquired or by the expiry of the five year term, should a decline in the Companys share price mean the value of
shareholdings does not equal 50 per cent of the amount of base annual fees, directors are not required to acquire shares to increase their level of shareholding to equal the amount of 50 per cent of the base annual fees.

Native Title in Australia

Native title describes the rights and interests of Aboriginal and Torres Strait Islander people in land and waters according to their traditional laws and customs as recognized by the common
law of Australia.

Native title law has evolved through judicial decisions and the enactment of legislation. The first
significant High Court decision on the subject of native title was Mabo v Queensland (No 2) (1992) 175 CLR 1 (the Mabo decision) in 1992, in which the Court recognized the concept of native title and said that Aboriginal and Torres Strait
Islander people who have maintained their connection with their land according to their laws and customs may hold native title. Proving connection usually involves showing that traditional laws and customs have been passed down through generations
of Aboriginal or Torres Strait Islander people to the present day. The native title of a particular group will depend on the traditional laws and customs of those people. Recent decisions have indicated that native title may change over time.

The Mabo decision also recognized that native title could be extinguished (removed) prior to the enactment of the Racial
Discrimination Act 1975 (Cth) (October 31, 1975) by government legislation or inconsistent executive action. In response to the Mabo decision, the Commonwealth Government enacted the Native Title Act 1993 (Cth) (NTA) which validated acts done and
granted by it prior to January 1, 1994 (past acts) and allowed the States and Territories to enact their own validation legislation. Subsequent amendments also validated grants (intermediate period acts) made by the Commonwealth (and allowed
the States and Territories to enact similar legislation) relating to certain grants up to December 23, 1996. The NTA also created the National Native Title Tribunal, responsible for mediation of native title claims and the administration of
certain procedures under the NTA. Finally, the NTA specifies the conditions to be satisfied and the procedures to be followed in order for acts done after January 1, 1994 (future acts) to be valid with respect to native title.

Native title may exist in areas where it has not been extinguished. Although a determination of native title does not invalidate
anothers validly granted tenure, the High Court decision in the Wik Peoples v Queensland (1996) 187 CLR 1 (Wik) case, made it clear that native title may co-exist with other forms of tenure where that tenure is not exclusive, provided the
native title rights are not incompatible with the exercise of the other rights.

In August 2002, the High Court handed down
its decision in the State of Western Australia v Ward (2002) 213 CLR 1 (Ward). The Court found, among other things, that native title can be categorized as a  bundle of rights, that there could be partial extinguishment of native
title rights and that Western Australian and Northern Territory mining and petroleum legislation extinguishes all native title rights that may have existed over minerals and petroleum in Western Australia and Northern Territory. The High Court also
held that a mining lease under the relevant Western Australian legislation extinguished any native title right to control access to land, or to be asked permission to use, or have access to, land but does not necessarily extinguish all native title
rights. This decision, which provides some clarity about the impact of native title on pastoral leases and mining leases in Western Australia and the Northern Territory is significant to AofA because some of its operations are in Western Australia.
However, the decision also leaves many issues to be decided on a case by case basis.

There are current native title claims
awaiting determination in the Federal Court of Australia over areas that include AofAs Mining Lease (ML) 1SA (Western Australia) (the Alcoa Lease). The native title claim which includes a portion of the conveyor associated with Alcoas
45% interest in the Portland Smelter (Victoria) has been determined.

FINANCIAL INFORMATION







(a) Western Australia

AofAs operations fall within the Gnaala Karla Booja native title claim (Federal Court file number WAD6274/98) and the Combined
Single Noongar claim (WAD6006/03), both of which are yet to be determined.

These claims include the Alcoa Lease. However, as
a result of the Ward decision, the potential exposure of AofA to this claim is significantly reduced by the High Courts finding that any native title right in minerals (if it could be established on the evidence) has been extinguished.

(b) Victoria

AofAs interest in Portland Smelter falls within the two of the Gunditjmara native title claims, namely Gunditjmara #1 (VID6004/98) and Gunditjmara #2 (VID655/06). In March 2007, these two claims
were heard together and, in combination, were further split into Part A and Part B areas pursuant to Orders of Justice North on January 18, 2007. The claims in respect of Part A were determined by consent in March 2007.

The Portland Smelter is situated on a freehold title and all validly granted freehold titles were excluded from the claim. Part A of the
claims only affected a small portion of the land on which the Portland Conveyor is situated pursuant to a Conveyor Licence Agreement. Native title was determined to subsist in a part of that land. The Gunditjmara native title consists of
non-exclusive rights to access, enjoy, camp on or take resources from the relevant part of that land where native title subsists.

Alcoa Portland withdrew from Part B of the claim on confirming that none of its interests were impacted by that part of the claim.

(c) General

While native title does and may still exist in the
above Western Australian and Victorian claim areas, all valid grants of tenure over the years will prevail to the extent of any inconsistency. The validity of AofAs tenure has not been challenged and AofA does not know of any basis upon which
such tenure may be found invalid. Accordingly, AofA is entitled to continue its operations not withstanding any native title rights and interests subsisting in those areas.

AWAC Litigation

In the ordinary course of its business, AWAC is involved
in a number of lawsuits and claims, both actual and potential, including some that it has asserted against others. While the amounts claimed may be substantial, the ultimate liability cannot now be determined because of the considerable
uncertainties that exist. It is possible that results of operations or liquidity in a particular period could be materially affected by certain contingencies.

Juruti

As previously reported, on November 30, 2010, Alcoa
Alumínio S.A. (Alumínio) received service of a lawsuit that had been filed by the public prosecutors of the State of Pará in Brazil in November 2009. The suit names the Company 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 the Company. 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.
Alumínio 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 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 Aluminios obligations arising out of such license,
that the licensing process is valid and legal, and that the suit is meritless. Alcoas stated position is that any impact from the project had been fully repaired when the suit was filed. Alcoa also believes that Jara Lake has not been affected
by any project activity and any evidence of pollution from the project would be unreliable. Following the preliminary injunction, the plaintiffs have taken no further action. Alcoa 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, Alumina Limited is unable to reasonably predict an outcome or to estimate a range of reasonably possible loss.

St Croix proceedings

As previously reported, in September 1998, Hurricane Georges struck the U.S. Virgin Islands, including the St. Croix Alumina, L.L.C. (SCA)
facility on the island of St. Croix. The wind and rain associated with the hurricane caused material at the location to be blown into neighbouring residential areas. SCA undertook or arranged various clean-up and remediation efforts. The Division of
Environmental Protection (DEP) of the Department of Planning and Natural Resources (DPNR) of the Virgin Islands Government issued a Notice of Violation that Alcoa has contested. In February 1999, certain residents of St. Croix commenced a civil suit
in the Territorial Court of the Virgin Islands seeking compensatory and punitive damages and injunctive relief for alleged personal injuries and property damages associated with bauxite or red dust from the SCA facility. In September
2009, the Court granted defendants motion for summary judgment on the class plaintiffs claim for injunctive relief. In October 2009, plaintiffs appealed the Courts summary judgement order dismissing the claim for injunctive relief
and in March 2011, the U.S. Court of Appeals for the Third Circuit dismissed plaintiffs appeal of that order. In September 2011, the parties reached an oral agreement to settle the remaining claims in the case which would resolve the personal
property damage claims of the 12 remaining individual plaintiffs. On March 12, 2012, final judgement was entered in the District Court for the District of the Virgin Islands. AWACs share of the settlement is fully insured. On
March 23, 2012, plaintiffs filed a notice of appeal of numerous non-settled matters, including but not limited to discovery orders, Daubert rulings, summary judgment rulings, as more clearly set out in the settlement agreement/release between
the parties. Plaintiffs appellate brief was filed in the Third Circuit Court on January 4, 2013, together with a motion seeking leave to file a brief of excess length. The court has suspended the remainder of the briefing schedule,
including the date for AWACs reply brief, until it rules on plaintiffs motion to file its brief of excess length. The Third Circuit Court of Appeals issued a new scheduling order regarding briefing in the matter. The matter has been
fully briefed with plaintiffs brief filed on November 25, 2013 and the matter is now before the court.

On
April 23, 2004, St Croix Renaissance Group, LLLP. (SCRG), Brownfield Recovery Corp, and Energy Answers Corporation of Puerto Rico (collectively referred to as Plaintiffs) filed a suit against SCA and Alcoa World Alumina LLC (AWA LLC) in
the Territorial Court of the Virgin Islands, Division of St Croix for claims related to the sale of SCAs former St Croix alumina refinery to Plaintiffs. SCA and AWA LLC thereafter removed the case to federal court and after a
several year period of discovery and motion practice, a jury trial on the matter took place in St Croix from January 11, 2011 to January 20, 2011. The jury returned a verdict in favour of Plaintiffs and awarded damages as described:
on a claim of breaches of warranty, the jury awarded $13 million; on the same claim, the jury awarded punitive damages in the amount of $6 million; and on a negligence claim for property damage, the jury awarded $10 million.

On February 17, 2011, SCA and AWA LLC filed post-trial motions seeking judgement, notwithstanding the verdict or, in the
alternative, a new trial. On May 31, 2011, the court granted SCAs and AWA LLCs motion for judgement regarding Plaintiffs $10 million negligence award and denied the remainder of SCAs and AWA LLCs motions.
Additionally, the court awarded Plaintiffs pre-judgement interest of $2 million on the breach of warranty award. As a result of the courts post-trial
decisions, AWAC recorded a charge of $20.3 million in 2011. On June 14, 2011, SCA and AWA LLC filed a notice of appeal with the U.S. Court of Appeals for the Third Circuit regarding SCAs and AWA LLCs denied post-trial motions. On June 22, 2011, SCRG filed a notice of cross appeal with the Third Circuit Court related to certain pre-trial decisions of the court and of the
courts post-trial ruling on the negligence claim. The Third Circuit referred this matter to mediation as is its standard practice in appeals. Following mediation and further, separate settlement
discussions, the parties executed an agreement dated September 30, 2011 resolving the matter in its entirety, and subsequently jointly petitioned (i) the District Court to release SCA and AWA LLC from the jury verdict and (ii) the
Third Circuit Court of Appeals to dismiss this matter. On March 13, 2012, the District Court entered an order discharging SCA and AWA LLC from the jury verdict and, on March 14, 2012, the Third Circuit Court of Appeals dismissed the
matter. This matter is now fully resolved.

As previously reported on January 14, 2010, Alcoa was served with a complaint
involving approximately 2,900 individual persons claimed 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 property 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. The complaint names as defendants the same entities as were sued in the February 1999 action described above and
have added as a defendant the current owner of the alumina facility property. In February 2010, Alcoa and SCA removed the case to the federal court for the District of Virgin Islands. Subsequently, plaintiffs have filed motions to remand the case to
territorial court as well as a third amended complaint, and defendants have moved to dismiss the

case for failure to state a claim upon which relief can be granted. On March 17, 2011, the court granted plaintiffs motion to remand to territorial court. Thereafter, Alcoa filed a
motion for allowance of appeal. The motion was denied on May 18, 2011. The parties await assignment of the case to a trial judge. At present, Alumina Limited is unable to reasonably predict an outcome or to estimate a range of reasonably
possible loss.

As previously reported, on March 1, 2012, Alcoa was served with a complaint involving approximately 200
individual persons claimed 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 property since the time of the hurricane in September 1998. This
complaint, Abraham, et al. v Alcoa, et al. alleges claims essentially identical to those set forth in the Abednego v Alcoa complaint. The matter was originally filed in the Superior Court of the Virgin Islands, St. Croix Division, on March 30,
2011. By motion filed March 12, 2012, Alcoa sought dismissal of this complaint on several grounds, including failure to timely serve the complaint and being barred by the statute of limitations. The motion is still pending. At present, Alumina
Limited is unable to reasonably predict an outcome or to estimate a range of reasonably possible loss.

Alba Proceeding
(Civil Action number 08-299, styled Aluminium Bahrain BSC v Alcoa Inc, AWA LLC, William Rice, and Victor Dahdaleh)

The
Alba Proceeding was settled in relation to Alcoa and AWA LLC in October 2012, without any admission of liability, by a cash settlement payment of $85 million, to be paid by AWA LLC in two equal instalments by the first anniversary of the
settlement. Based on the settlement agreement with Alba, AWA LLC recorded a charge of $85 million in 2012 in respect of the Alba Proceeding. In addition, AWA LLC entered into a long term alumina supply agreement with Alba.

Resolution of U.S. Government Investigation relating to Alba Proceeding

On 9 January 2014, Alcoa Inc announced the resolution of the investigations by the US Department of Justice (DOJ) and the
US Securities and Exchange Commission (SEC) regarding certain legacy alumina contracts with Aluminium Bahrain BSC.

The
settlement with the DOJ was reached with Alcoa World Alumina LLC (AWA). AWA is a Company within Alcoa World Alumina and Chemicals (AWAC). As part of the DOJ resolution, AWA will pay a total of $223 million, including a fine of $209 million payable
in five equal instalments over four years. The first instalments of $41.8 million, plus a one-time administrative forfeiture of $14 million, were paid in the first quarter of 2014, and the remaining instalments of $41.8 million each will be
paid in the first quarters of 2015-2018.

Alcoa Inc 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 Foreign Corruption Practices Act. Under the terms of the settlement with the SEC, Alcoa Inc agreed to a settlement amount of $175 million, but will be given
credit for the $14 million one-time forfeiture payment, which is part of the DOJ resolution, resulting in a total cash payment to the SEC of $161 million payable in five equal instalments over four years. The first instalment of $32.2 million was
paid to the SEC in the first quarter of 2014, and the remaining instalments of $32.2 million each will be paid in the first quarters of 2015-2018.

Derivative Actions

As previously reported, on July 21, 2008,
the Teamsters Local #500 Severance Fund and the Southeastern Pennsylvania Transportation Authority filed a shareholder derivative suit in the civil division of the Court of Common Pleas of Allegheny County, Pennsylvania against certain officers and
directors of Alcoa claiming breach of fiduciary duty, gross mismanagement, and other violations. This derivative action stems from the civil litigation brought by Alba against Alcoa Inc, AWA LLC, Victor Phillip Dahdaleh, and others, and the
subsequent investigation of Alcoa Inc by the DOJ and the SEC with respect to Albas claims. This derivative action claims that the defendants caused or failed to prevent the matters alleged in the Alba lawsuit. The director defendants filed a
motion to dismiss on November 21, 2008. On September 3, 2009, a hearing was held on Alcoa Incs motion and, on October 12, 2009, the court issued its order denying Alcoa Incs motion to dismiss but finding that a derivative
action during the conduct of the DOJ investigation and pendency of the underlying complaint by Alba would be contrary to the interest of shareholders and, therefore, stayed the case until further order of the court. This derivative action is in its
preliminary stages and Alcoa Inc is unable to reasonably predict an outcome or to estimate a range of reasonably possible loss.

As previously reported, on March 6, 2009, the Philadelphia Gas Works Retirement Fund filed a shareholder derivative suit in the
civil division of the Court of Common Pleas of Philadelphia County, Pennsylvania. This action was brought against certain officers and directors of Alcoa claiming breach of fiduciary duty and other violations and is

based on the allegations made in the previously disclosed civil litigation brought by Alba against Alcoa Inc, AWA LLC, Victor Phillip Dahdaleh, and others, and the subsequent investigation of
Alcoa Inc by the DOJ and the SEC with respect to Albas claims. This derivative action claims that the defendants caused or failed to prevent the conduct alleged in the Alba lawsuit. On August 7, 2009, the director and officer defendants
filed an unopposed motion to coordinate the case with the Teamsters Local #500 suit, described immediately above, in the Allegheny County Common Pleas Court. The Allegheny County court issued its order consolidating the case on September 18,
2009. Thereafter, on October 31, 2009, the court assigned this action to the Commerce and Complex Litigation division of the Allegheny Court of Common Pleas and on November 20, 2009, the court granted defendants motion to stay all
proceedings in the Philadelphia Gas action until the earlier of the court lifting the stay in the Teamsters derivative action or further order of the court in this action. This derivative action is in its preliminary stages and Alcoa Inc is unable
to reasonably predict an outcome or to estimate a range of reasonably possible loss.

As previously reported, on June 19,
2012, Catherine Rubery (plaintiff) filed a shareholder derivative suit in the United States District Court for the Western District of Pennsylvania against William Rice, Victor Dahdaleh and current and former members of the Alcoa Inc Board of
Directors (collectively, defendants) claiming breach of fiduciary duty and corporate waste. This derivative action stems from the previously disclosed civil litigation brought by Alba against Alcoa Inc, and the subsequent investigation of Alcoa Inc
by the DOJ and the SEC as described above. This derivative action claims that defendants caused or failed to prevent illegal bribes of foreign officials, failed to implement an internal controls system to prevent bribes from occurring and wasted
corporate assets by paying improper bribes from incurring substantial legal liability. Furthermore, plaintiff seeks an order of contribution and indemnification from defendants. The derivative action is in its preliminary stage and Alcoa Inc is
unable to reasonably predict an outcome or to estimate a range of reasonably possible loss.

Other Financial Information

Dividend Policy

Generally the Board intends, on an annual basis, to distribute cash from operations after debt servicing and corporate costs commitments have been met. The Board will also consider the capital structure
of Alumina Limited, the capital requirements for the AWAC business and market conditions. Dividends will be fully franked for the foreseeable future.

No dividend was declared by the Directors for 2013. The decision not to pay a dividend for 2013 is based on the above policy to conserve cash, given the current market conditions. The Boards policy
is to review dividend payments at each half year in light of the current and expected business conditions.

Net interest charged to profit was $25.0 million for the year ended December 31, 2013 due to lower
average net borrowings offset by the write-off of unamortised establishment fees relating to the bank facilities that were terminated during 2013 compared to $29.3 million for the year ended December 31, 2012. Net interest charged to profit was
$29.3 million for the year ended December 31, 2012 due to the overall increase in net debt position compared to $28.3 million for the year ended December 31, 2011 partially offset by lower commitment and upfront fees.

public company limited by shares under the Corporations Act 2001 of the Commonwealth of Australia (the Corporations Act) and is registered with Australian Business Number 85 004 820 419. It is listed on the Australian Securities Exchange (the ASX).

The Constitution was adopted by shareholders at the Annual General Meeting held on May 7, 2009. The Constitution does not
specify Alumina Limiteds objects and purposes. Rather, under section 124 of the Corporations Act, Alumina Limited has the legal capacity and powers of an individual, and all the powers of a body corporate.

Directors Powers & Qualifications

Subject to the Corporations Act and the ASX listing rules (the Listing Rules), a director who has an interest in a matter may vote in respect of that matter if it comes before the directors, and be
counted as part of the quorum (rule 59(b)(i)). Pursuant to section 195 of the Corporations Act, a director who has an interest in a matter is only permitted to vote in respect of that matter if either: that interest does not need to be disclosed to
the other directors under the Corporations Act; or the directors who do not have an interest in the matter have passed a resolution that identifies the director, the nature of the directors interest in the matter and its relation to the
company, and also that the directors are satisfied that the interest should not disqualify the director from voting; or the Australian Securities and Investments Commission by declaration or order permits that to occur.

Directors are to be paid for their services. Each non-executive director is to be paid or provided remuneration for services, determined
by the directors, at the time and in the manner determined by the directors, the total amount or value of which in any year may not exceed an amount approved by Alumina Limited in general meeting. An executive director may be appointed on terms as
to remuneration, tenure of office and otherwise, as may be determined by the directors (rules 48(a), (b) and (g)).

The
directors can be paid remuneration in kind (i.e. other than in cash), provided that any amount paid to a director other than in cash does not exceed in value the amount that they would be entitled to receive if the remuneration were paid in cash
(rule 48(d)).

In addition, the directors are also entitled to be paid or reimbursed for all travelling and other expenses
properly incurred by them in attending and returning from any meeting of the directors or of Alumina Limited (rule 48(e)).

If
any director, with the approval of the directors, performs extra services or makes any special exertions for the benefit of Alumina Limited, that director may receive special and additional remuneration as determined by the directors, having regard
to the value of the extra services or special exertions. Any special or additional remuneration must not include a commission on or percentage of profits or operating revenue or turnover (rule 48(f)).

The Constitution does not contain any age limit requirement for the retirement of directors.

Directors are not required to hold shares in the capital of Alumina Limited (rule 46).

A director may not hold office for a continuous period in excess of three years or past the third Annual General Meeting following the
directors appointment, whichever is the longer, without submitting for election or re-election. If no director would otherwise be required to submit for election or re-election but the Listing Rules

require that an election of directors be held, the director to retire at the Annual General Meeting is the director who has been longest in office since their last election. Where the
longest-serving directors were elected on the same day, absent agreement, the director to retire is determined by ballot (rule 47(a)).

Rights & Restrictions Attaching to Each Class of Shares

Alumina
Limited has only one class of shares on issue, i.e. ordinary class. The rights attached to ordinary shares include the right to dividends in the event that the directors determine that a dividend is payable. The directors may fix the amount, the
time for payment and the method of payment of a dividend. Dividends may be paid by the payment of cash, the issue of shares, the grant of options and the transfer of assets, including shares in another body corporate (or any combination of them)
(rule 67(a)).

Subject to law, all unclaimed dividends may be invested or otherwise used by the directors for the benefit of
Alumina Limited until claimed or disposed of according to law (rule 71(d)).

The voting right attached to ordinary shares is
the right to vote in person or by proxy, by attorney or, where the shareholder is a body corporate, by representative at meetings of shareholders (rule 41 (a)).

On a show of hands, each shareholder (regardless of the number of shares held) has one vote (rule 41(b)(i)). On a poll, each shareholder may exercise one vote for each fully paid ordinary share held. In
respect of a partly paid share, each shareholder has that fraction of a vote equivalent to the proportion which the amount paid up on that share bears to the total amount paid and payable for that share (rule 41 (c)).

A shareholder is not entitled to vote at a general meeting or to be counted for the purpose of constituting a quorum unless all calls and
other sums presently payable by the shareholder in respect of shares have been paid (rule 42).

For the purposes of determining
voting entitlements at a general meeting, shares will be taken to be held by those persons recorded in the register of members at the time and date determined by the directors under regulations 7.11.37 and 7.11.38 of the Corporations Regulations
2001 of the Commonwealth of Australia.

Dividends are not able to be paid by Alumina Limited unless:



| |  |  | Alumina Limiteds assets exceed its liabilities immediately before the dividend is declared and the excess is sufficient for the payment of the
dividend;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the payment of the dividend is fair and reasonable to Alumina Limiteds shareholders as a whole; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the payment of the dividend does not materially prejudice Alumina Limiteds ability to pay its creditors, (section 254T of the Corporations Act).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------

In the event of a winding up, ordinary shares rank equally in the division of any surplus (section 555 of
the Corporations Act).

Shareholders cannot redeem ordinary shares.

The holders of fully paid ordinary shares have no further liability to Alumina Limited in respect of those shares. The holders of partly
paid shares are liable to Alumina Limited once a call is made for the payment of the unpaid amount (rule 21(a)).

There is no
provision in the Constitution which discriminates against an existing or prospective shareholder as a result of that shareholder owning a substantial number of shares unless such ownership leads to a proportional takeover bid (see heading
Proportional Takeover Approval below).

To vary or cancel the rights attached to ordinary shares, a special resolution
approving the variation or cancellation must be passed at a special meeting of the holders of ordinary shares, or by consent in writing signed by the holders of at least three fourths of the issued ordinary shares (section 246B(2) of the
Corporations Act).

Unless otherwise provided by the terms of issue, the issue of any new shares ranking equally with existing
shares (whether in the same or a different class) is not a variation of the rights conferred on the holders of the existing shares (rule 5(b)).

The directors may refuse to register any transfer of shares if permitted to do so under the Listing Rules (rule 25(a)(iii)).

General Meetings of the Company

By a resolution of the directors, a general meeting of Alumina Limited may be convened at the time and place or places and in the manner
determined by the directors. No shareholder may convene a general meeting of Alumina Limited unless entitled to do so under the Corporations Act (rule 30).

Where the company has called a general meeting, notice of the meeting may be given in the form and manner in which the directors determine (rule 31). At least 28 days notice must be given of a
general meeting (section 249HA of the Corporations Act).

All shareholders may attend general meetings in person, or be
represented by the attendance of a proxy, attorney or, where the shareholder is a body corporate, a representative, none of whom need be shareholders of Alumina Limited in their own right (rule 41).

The quorum for a general meeting is three members present in person or by proxy, by attorney or, where the shareholder is a body
corporate, by representative (rule 33(b)). If there is not a quorum within 30 minutes after the time specified in the notice of the meeting, the meeting is dissolved unless the chair or the directors adjourn the meeting to a date, time and place
determined by the chair and the directors. If no quorum is present at any adjourned meeting within 30 minutes after the time for the meeting, the meeting is dissolved (rule 33(c)).

Limitations on the Right to Own Securities

Alumina Limiteds Constitution does not impose limitations on the right to own securities.

However, the rights of non-resident or foreign shareholders to hold or exercise voting rights on Alumina Limiteds securities are subject to the Foreign Acquisitions and Takeovers Act 1975of
the Commonwealth of Australia. The Treasurer of the Australian Federal Government has the power to prohibit the acquisition of a controlling interest in any Australian company by a foreign person or foreign persons, if the Treasurer is of the
opinion that the acquisition would be contrary to the national interest. For this purpose, a shareholding of 15% or more held by a single foreign person or 40% or more held by two or more foreign persons is deemed to constitute a controlling
interest. The notion of a controlling interest is not restricted to actual shareholdings or voting power but includes potential voting power (i.e. voting power that may come into existence into the future) and rights to be issued shares in future
such as options and convertible notes.

In addition, section 50 of the Competition and Consumer Act 2010 of the Commonwealth of
Australia prohibits an acquisition of shares that would have the effect, or be likely to have the effect, of substantially lessening competition in any market for goods or services within Australia, unless the acquisition is authorised by the
Australian Competition and Consumer Commission.

Finally, while not a direct limitation on the right to own securities, the
Constitution does permit Alumina Limited to manage its shareholder base by selling the securities of a shareholder who holds less than a marketable parcel of securities, subject to certain procedures being followed (rule 76).

Proportional Takeover Approval

Where a proportional takeover bid is made under the Corporations Act for shares in Alumina Limited (i.e. a bid is made for a specified proportion, but not all, of each holders bid class shares), the
registration of any transfer of shares giving effect to a takeover contract under the proportional takeover bid is prohibited unless and until a resolution to approve the proportional takeover bid is passed in accordance with rule 80 of the
Constitution (rule 79). The resolution is to be considered at a meeting convened and conducted by Alumina Limited, of the persons entitled to vote on the resolution (rule 80(c)). The resolution is taken to have been passed if the proportion that the
number of votes in favour of the resolution bears to the total number of votes on the resolution is greater than one half (rule 80(d)). The provisions with respect to proportional takeover bids (i.e. rules 79 and 80) cease to have effect on the
third anniversary of the date of their adoption or last renewal. The provisions were last adopted by shareholders on May 2, 2012, therefore they will operate until May 2, 2015, unless renewed earlier.

Disclosure of Share Ownership

The Constitution does not prescribe an ownership threshold above which shareholders must disclose their holding to Alumina Limited.
However, Part 6C.1 of the Corporations Act imposes disclosure requirements on persons who acquire or cease to hold a substantial holding in Alumina Limited (see section 9 of the Corporations Act for the definition of substantial holding). The
disclosure must be given to Alumina Limited and the ASX within the prescribed time.

Changes in Share Capital

Alumina Limited may reduce or alter its share capital in any manner provided for by the Corporations Act (rule 29).

Alumina Limited may reduce its share capital or buy back shares in accordance with the Corporations Act.

C. Material Contracts

Formation Agreement among Aluminum Company of America, Alcoa International Holdings Corporation, ASC Aluminium Inc., Alumina Limited and certain subsidiaries of the companies that established AWAC.

On December 21, 1994, Alcoa and WMC finalised and executed the AWAC Agreements establishing and governing the
operation of AWAC, with the Formation Date of AWAC being 1 January 1995. The main AWAC Agreements are the agreements known respectively as the Formation Agreement and the Charter of the Strategic Council. Key aspects of
the AWAC Agreements are set out below. Copies of the main AWAC Agreements are also annexed to this Report as exhibits.

(a) Enterprise

AWAC is comprised of a series of affiliated operating entities in which Alcoa has a 60% interest and Alumina Limited a 40% interest. Alcoa acquired 9% of AofA and Alumina Limited acquired a 40% interest
in the other Alcoa affiliated operating entities and assets included within AWAC, upon its formation. Alumina Limited has acquired a 40% interest in AWAC entities and assets acquired (such as that of San Ciprian) since AWACs formation.

(b) Consideration

On January 1, 1995, Alumina Limited paid to Alcoa approximately $386 million and transferred 9% of AofA to Alcoa. Alumina Limited contributed an additional sum of approximately $120 million to AWAC
which was repaid during the course of initial establishment and operation of AWAC and for further acquisitions. Alcoa was also to receive additional compensation based upon the future earnings of AWACs alumina-based industrial chemicals
operations if the earnings exceeded performance targets for the period 1995-1999 (inclusive). Since the growth plan for the alumina-based chemicals business was not achieved, this additional compensation was not required to be paid by WMC.

(c) Enterprise Scope

The scope of AWAC includes the following:

Bauxite and alumina: the
exploration, searching and prospecting for and the mining of bauxite and other aluminous ores as well as the refining and other processing of these ores into alumina.

Industrial chemicals: the research, development, production, marketing and sale of industrial chemicals, comprised initially of the output of the existing AofA facilities for industrial
alumina-based chemicals and other agreed mineral-based chemicals or as may be agreed from time to time.

Integrated
operations: the ownership and operation of certain primary aluminium smelting, aluminium fabricating and other necessary but ancillary facilities that are run as part of an integrated operation at certain of the locations existing on the
formation of AWAC.

(d) Formation

The formation of AWAC was completed on January 1, 1995.

(e) Role of the parties

Industrial leader

Under the general direction of the Strategic Council, Alcoa is the industrial leader and provides the operational management of AWAC and of all affiliated operating entities within AWAC,
unless Alcoa requests Alumina Limited to manage a particular operation.

Strategic Council

The Strategic Council is the principal forum for Alcoa and Alumina Limited to provide direction and counsel to the AWAC entities in
respect of strategic and policy matters. The Alcoa and Alumina Limited representatives on the boards of the AWAC entities are required, subject to their general fiduciary duties, to carry out the directions and the decisions of the Strategic
Council. The Strategic Council has five members, three appointed by Alcoa (of which one is Chairman) and two by Alumina Limited (of which one is the Deputy Chairman). Decisions are made by majority vote except for matters which require a super
majority vote, which is a vote of 80% of the members appointed to the Strategic Council.

The following decisions
require a super majority vote:



| |  |  | a change of the scope of AWAC;
| | - |  | ------------------------------



| |  |  | a change in the dividend policy;
| | - |  | --------------------------------



| |  |  | sale of all or a majority of the assets of AWAC;
| | - |  | ------------------------------------------------



| |  |  | equity calls on behalf of AWAC totalling in any one year in excess of $1 billion; and
| | - |  | -------------------------------------------------------------------------------------



| |  |  | loans to Alcoa or Alumina Limited, or their respective affiliates by AWAC (including loans between AWAC entities).
| | - |  | ------------------------------------------------------------------------------------------------------------------

The Strategic Council meets as frequently as the Chairman after consultation with the Deputy Chairman determines, but meetings of the
Council must be held at least twice a year. The Deputy Chairman may require additional meetings to be held.

Other
management and personnel roles

Alumina Limited is entitled to representation in proportion to its ownership interest on
the board of each entity in the AWAC structure, including AofA. In addition to the Strategic Council meetings, meetings of key AWAC subsidiary companies (with representatives from Alcoa and Alumina Limited) are held typically up to four times a year
..

(f) Exclusive Vehicle

AWAC is the exclusive vehicle for the pursuit of Alumina Limiteds and Alcoas (and their affiliates as defined) interests in the bauxite, alumina and inorganic industrial (alumina-based)
chemicals businesses included within the scope of AWAC, and neither party can compete, within that scope, with AWAC so long as they maintain an ownership interest in AWAC. In addition, Alumina Limited may not compete with the businesses of the
integrated operations of AWAC (being the primary aluminium smelting and fabricating facilities and certain ancillary facilities that exist at the formation of AWAC).

If either party acquires a new business which has as a secondary component a bauxite, alumina or inorganic industrial chemicals business included within the scope of AWAC, that business must be offered to
AWAC for purchase at its acquisition cost or, if not separately valued, at a value based on an independent appraisal of the business. If the companies within AWAC and the Strategic Council elect not to accept the offer, the business must be divested
by Alcoa or Alumina Limited (as the case may be) to a third party that is not an affiliate.

Smelting is not subject to these
exclusivity provisions, although there are certain smelting assets in AWAC, primarily those in AofA in which Alumina Limited already had an interest at the time AWAC was formed.

It should be noted that the AWAC Agreements do not expressly address the position of an acquirer of Alumina Limited or Alcoa, where that
acquirer already operates a bauxite, alumina or industrial (alumina-based) chemicals business. Such an acquirer would be an affiliate of Alumina Limited or Alcoa (as relevant) and therefore the exclusive vehicle provisions of the AWAC
agreements would apply. However, the agreements are silent on the action



- 83 -

ADDITIONAL INFORMATION







that Alumina Limited or Alcoa (as relevant) and the acquirer must take. The relevant business could be offered to AWAC for purchase, with the value to be agreed. Alternatively, the acquirer might
divest itself of the relevant business or undertake some other action consistent with the exclusive vehicle provisions of the AWAC Agreements.

(g) Capital requirements

The cash flow of AWAC and borrowings are
the preferred sources of funding for the needs of AWAC. Should the aggregate annual capital budget of AWAC require an equity contribution from Alcoa and Alumina Limited, the following limits apply:



|(i) | With respect to amounts up to $500 million in annual equity requested to be contributed in total by Alcoa and Alumina Limited to AWAC (including amounts requested
pursuant to paragraphs (g)(ii) and (g)(iii)), each party must contribute its proportionate share based on its current ownership in AWAC. If either party does not contribute its proportionate share, the other party may make up the contribution, in
addition to its own contribution, and the non-contributing partys interest in AWAC will be diluted in accordance with an agreed formula.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(ii) | With respect to annual equity requests in excess of $500 million but less than $1 billion, each party must declare within 30 days of when the equity request is made if
it has the ability to fund its share of the request and, if so, each party must contribute its proportionate share. Should Alumina Limited be unable to contribute the full amount of the equity in the year required, the parties will work together to
find alternative interim external financing arrangements reasonably acceptable to Alumina Limited for AWAC or for Alumina Limited, or Alumina Limited may choose to have its interest in AWAC diluted in accordance with the formula noted above. If
alternative external financing is not acceptable to Alumina Limited, Alcoa may fund the Alumina Limited proportionate share and this contribution will be deemed to be a loan by Alcoa to Alumina Limited at the current market rate for Alcoas
long-term borrowings. Alumina Limited must repay the amount contributed on its behalf in a period not to exceed one year. If either party does not contribute its share or Alumina Limited does not repay the loan after one year and contribute its
share, the dilution provision referred to above applies.
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(iii) | With respect to annual equity requests in excess of $1 billion approved by a super majority vote, each party must contribute its proportionate share. However, if
Alumina Limited is unable to contribute the full amount of the equity in the year required, the parties must work together to find alternative financing arrangements reasonably acceptable to Alumina Limited for AWAC or for Alumina Limited. If
Alumina Limited does not contribute the balance of its full proportionate share, Alcoa may make, and must be compensated for, all or part of the remaining contribution in Alumina Limiteds place. However, if this occurs, Alumina Limiteds
interest in AWAC will only be diluted in accordance with the dilution provision referred to in paragraph (i) above in respect of Alcoas contribution to the capital requirements up to $1 billion. If Alcoa elects to proceed, Alcoa and
Alumina Limited will review the mechanism to compensate Alcoa for its excess contribution, which may include a disproportionate allocation of returns associated with the excess contribution.
|----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(iv) | The $500 million and $1 billion will be increased by the amount of quarterly dividends paid in the relevant financial year with respect to valid calls that are funded
by equity contributions (or if funded only in part by equity contributions, to the extent of such equity funding) in accordance with clause 4.4(b) of the Enterprise Funding Agreement (see the Enterprise Funding Agreement attached hereto as Exhibit
4.1.12 for further clarification).
|---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(h) Dividend policy

AWAC must distribute by way of dividends, in each financial year, at least 30% of the net income of the prior year of each of the entities
comprising AWAC, unless the Strategic Council agrees by a super majority vote to pay a smaller dividend. AWAC must also endeavour to distribute dividends above 30% of the net income of AWAC, consistent with prudent financial management and in the
context of the strategic and business objectives of AWAC.

ADDITIONAL INFORMATION







(i) Leveraging policy

The affiliated operating entities within AWAC must maintain a limit of debt (net of cash) in the aggregate equalling not more than 30% of
total capital, where total capital is defined as the sum of debt (net of cash) plus any minority interest plus shareholder equity.

(j) Pre-formation liabilities

Where AWAC sustains an extraordinary
liability (described below), Alcoa and Alumina Limited must, to the extent of their preformation ownership interest, indemnify, reimburse and hold harmless AWAC for such extraordinary liability. Certain matters including litigation, environmental
and industrial hygiene matters, and non-compliances with government regulations or permits are identified and responsibility allocated in the AWAC Agreements. An extraordinary liability is:



| |  |  | a liability to a third party claim at law or in equity
| | - |  | ------------------------------------------------------



| |  |  | a claim by any government or governmental agency
| | - |  | ------------------------------------------------



| |  |  | an environmental liability
| | - |  | --------------------------



| |  |  | an industrial disease or personal injury which relates to an act or omission that occurred totally or partially during a period prior to Formation
date.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

To be subject to the indemnity a claim or a series of quarterly related claims (other than those
specifically identified and referred to in the AWAC Agreements) must exceed an initial threshold amount of $250,000. For liabilities that involve both activities or operations before and after the formation of AWAC, the liabilities are allocated by
applicable methods as provided in schedules to the AWAC Agreements or, if none of those methods are relevant, by a fair and reasonable allocation of the responsibility for the extraordinary liability (based on an assessment of the respective
contributions to the extraordinary liability by pre-formation and post-formation activities among AWAC, Alcoa and Alumina Limited).

Costs relating to identified litigation and claims in Schedules 3.07, 4.06 and 8.02 to the Formation Agreement (set out as Exhibit 9) are deemed to be Extraordinary Liabilities under the Formation
Agreement. Schedule 3.07 sets out a range of lawsuits current as at January 1, 1995 which related to AWAC operations and which are no longer outstanding. Schedule 8.02 sets out allocation methods for various environmental liabilities
which relate to acts or omissions that occurred totally or partially during a period prior to AWACs formation.

(k) Alumina Limited pre-payment for AofA liabilities

By an amending agreement dated 31 December 1995, Alcoas purchase price for Alumina Limiteds 9% of AofA was adjusted, with
such adjustment being in full satisfaction of Alumina Limiteds indemnity obligations for environmental extraordinary liabilities (as defined in the AWAC Agreements and described above) that should reasonably have been known, or for known
environmental extraordinary liabilities, at plants in Australia, except for the cost of reclaiming spent pot lining stored at Portland. Alcoa assumed obligations to indemnify Alumina Limited for any such extraordinary liabilities.

(l) Dispute resolution

The AWAC Agreements mechanism prescribes for the resolution of all disputes, difference, controversies or claims between the parties in relation to AWAC. The mechanism employs an
escalating procedure for resolution.

(m) Transfer of interests

Rights of first refusal apply in relation to Alumina Limited and Alcoas interests in AWAC, or their affiliated holding interests in
AWAC.

In addition, without the other partys consent, neither party can transfer its interests in AWAC to a
competitor. For these purposes, a competitor is any person engaged in the mining of bauxite, the processing of alumina or inorganic chemicals or the production of primary aluminium, either directly itself or indirectly through any
company in which it holds, legally or beneficially, either 10% or more of the issued capital or 10% or more of the voting power.

Any increase or decrease in AWAC interests must be proportionate across all entities in AWAC unless the increase or decrease was the involuntary consequence of government action, in which case Alumina
Limited and Alcoa must consult as to the appropriate course of action.

There is no change of control clause triggered by an
upstream change of control of Alumina Limited or Alcoa.

(n) Material inequity

A principle agreed on the original formation of AWAC was that if either Alumina Limited or Alcoa believed eight years after the formation
of AWAC that a material inequity had resulted to them which substantially altered the value of a partys original contribution to AWAC, they could commence a procedure for making an adjustment to their contributions. Alcoa and Alumina Limited
have agreed, subsequent to a joint review in January 2003, that no such material inequity has occurred and no adjustment is to be made.

Enterprise Funding Agreement

Under the Enterprise Funding Agreement dated
September 18, 2006, AofA pays dividends in excess of 30% of its net income, to the extent required, to fund AWACs capital requirements (including AofAs own capital funding requirements). During 2010, the Enterprise Funding Agreement
was extended on the basis that two years notice is required to terminate the agreement.

Subscription Agreement

CITIC Resources Australia Pty Ltd, an indirect wholly-owned subsidiary of CITIC Resources Holdings Limited, and Bestbuy
Overseas Co Ltd, an indirect wholly-owned subsidiary of CITIC Limited (the CITIC entities) subscribed for 366,029,428 fully paid ordinary shares in Alumina Limited, being 15% of Alumina Limiteds then
current capital base, representing 13.04% of Alumina Limiteds capital base following completion (the Placement). The Placement raised approximately A$452 million, based on an issue price of A$1.235 per share.

The CITIC entities agree that their voting power and economic interest in the Company will not, without the Companys prior written
approval, exceed 15% for two years from February 14, 2013 and thereafter will not exceed 19.9% (subject to some exceptions relating to takeovers, schemes of arrangements and capital raising). The CITIC entities may, if interested in
acquiring more shares in the Company, in the two years from February 14, 2013, undertake discussions in good faith with the Company and the Company will give consideration to such acquisition. The CITIC entities are subject to certain
limitations in their right to dispose of the shares subscribed for, in the two years from February 14, 2013.

Alumina Limited was obliged to procure by March 15, 2013, the appointment of one nominee of the CITIC entities as a director of the
Company to fill a casual vacancy on the Board.

D. Exchange Controls

Various Australian legislation and regulations control the import and export of capital and remittance of payments involving non-residents
of Australia.

These include the Banking (Foreign Exchange) Regulations 1959 (Cth), counter-terrorism financing legislation
and tax-related legislation and regulations. Alumina Limited is not generally restricted from receiving funds into or transferring funds from Australia to the credit of non-residents of Australia but in certain cases is required to:



| | (i) | withhold Australian taxes
| | --- | -------------------------



| | (ii) | obtain the Reserve Bank of Australias authority to take or send out of Australia any Australian or foreign currency
| | ---- | --------------------------------------------------------------------------------------------------------------------



| | (iii) | obtain the Reserve Bank of Australias authority to place any sum in Australia to the credit of, or make any payment in Australia to, by order of or on behalf of,
a person who is not a resident of Australia
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | lodge a report of the transaction details.
| | ---- | ------------------------------------------

Furthermore, under the Autonomous Sanctions Act 2011 (Cth), the Governor-General, in consultation with the Minister, may make regulations prescribing foreign persons or entities, either for specific
purposes or more generally, or restricting dealings with assets and the supply, sale or transfer of goods and services to certain countries (which would include Ordinary Shares of the Company and remittance of associated payments by Alumina
Limited). Under the Autonomous Sanctions Regulations 2011 (Cth), Alumina Limited must not directly or indirectly make an asset available to, or for the benefit of, or hold or use an asset belonging to:



| |  |  | certain figures, sub-groups or individuals currently or formerly associated with the ruling regime in Burma (Myanmar)
| | - |  | ---------------------------------------------------------------------------------------------------------------------

The Autonomous Sanctions Regulations 2011 (Cth) also prohibit
Alumina Limited from having certain commercial dealings with defined people which may affect the export or payment of capital. Under the regulations, Alumina Limited must not:



| |  |  | supply, sell or transfer goods (including foreign currency) to another person that will be transferred, as a direct or indirect result of the supply,
sale or transfer, to Burma (Myanmar), Fiji, Iran, Syria or Zimbabwe for use in those countries, or for the benefit of those countries

The Charter of the United Nations Act 1945 (Cth) and the Charter of the United Nations (Dealing with Assets) Regulations 2008 (Cth) (the Regulations) also regulate certain transactions with designated
foreign persons. The Charter of the United Nations Act 1945 (Cth) and the Regulations enable Australia to give effect to decisions made by the United Nations Security Council. The Regulations accommodate provisions in the Charter of the United
Nations Act 1945 (Cth) which prohibit individuals or corporations from engaging in activities which contravene a United Nations sanction in force in Australia. The Regulations also give broad effect to Resolutions of the United Nations Security
Council (including the United Nations Security Council Resolution 1373 (2001) pertaining to terrorism) which impose obligations on member states to freeze funds, financial assets and economic resources within their territories and prevent the
use of or dealing with funds, financial assets or economic resources by, or the making of funds, financial assets or economic resources available to, any person or entity (including certain persons and entities engaged in terrorist acts) specified
by the United Nations Security Council as being subject to such sanctions. Transactions that involve a transfer of assets (which would include Ordinary Shares in the Company) to or from persons or entities listed under the Charter of the United
Nations Act 1945 (Cth) or the Regulations require ministerial approval.

The Regulations apply to all individuals and entities
defined by the Minister for Foreign Affairs of the Commonwealth of Australia as having met the definition established by the United Nations Security Council. That definition includes certain named individuals or entities prescribed by the United
Nations Security Council as being subject to financial sanctions associated with:



| |  |  | Al Qaida (also known as the Al-Qaeda organization) or other individuals, groups or entities associated with it

The Charter of the United Nations Act 1945 (Cth) also applies to other persons
or entities identified in relation to terrorist activities, as identified in regulations enacted by the Governor General of the Commonwealth of Australia or as listed by the Minister for Foreign Affairs of the Commonwealth of Australia from time to
time. The Minister for Foreign Affairs of the Commonwealth of Australia maintains a list of individuals and entities to which United Nations Security Council sanctions apply. That list includes (amongst others, and in addition to those individuals
and entities referred to above as being subject to financial sanctions by the United Nations Security Council) the Kurdistan Peoples Congress, the Al-Aqsa Foundation, Ansar al-Islam and the Orange Volunteers.

In addition, more general limitations under Australian laws, on the right of non-residents to acquire, hold or vote Ordinary Shares in
the Company, exist under the Foreign Acquisitions and Takeovers Act 1975 (Cth) (the Foreign Acquisitions Act) and section 606 of the Corporations Act 2001 (Cth) (the Corporations Act).

Under the Foreign Acquisitions Act, any acquisition or issue of shares or acquisition of rights constituting potential voting power (such
as options to acquire shares or convertible notes) which would increase or alter beyond 15% in the case of any single foreign interest, or 40% in the case of more than one foreign interest, the controlling interest of foreign entities or
persons in a corporation that carries on an Australian business is subject to review and approval by the Treasurer of the Commonwealth of Australia.

The Foreign Acquisitions Act permits the Treasurer to deny or refuse proposals where such proposals would be contrary to the Australian national interest.

Section 606 of the Corporations Act provides that, subject to certain exceptions, a person must not acquire a relevant interest in
voting shares in a company, if as a result a persons voting power in the company increases to more than 20%, or from a starting point that is above 20% and below 90%. Section 606 also prohibits a person acquiring a legal or equitable
interest in shares if, because of the acquisition, another person acquires a relevant interest in shares and someones voting power increases to more than 20%, or from a starting point that is above 20% and below 90%. Section 608 of the
Corporations Act provides that a person has a relevant interest in shares if that person holds the shares, or has power or control over the voting rights attaching to them or their disposal, whether directly or indirectly.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the applicable legislation and to
the Constitution. A copy of the Constitution is filed as Exhibit 1 to this Annual Report on Form 20-F.

E. Taxation

The following is a summary of the principal Australian and United States federal income tax consequences to United
States holders (as defined below) of the acquisition, ownership and disposition of ADS or Ordinary Shares that are held on capital account and is based on the laws in force as at the date of this Annual Report. Holders are advised to consult their
own tax advisers concerning the overall tax consequences of the acquisition, ownership and disposition of ADS or Ordinary Shares in their individual circumstances particularly where they are held on revenue account. This discussion relies in part on
representations by the Depositary in the Deposit Agreement and related documents.

Commonwealth of Australia Taxation

The dividend imputation system of company tax relieves double taxation on dividends paid by Australian resident corporations. Under this
system, companies are required to identify dividends paid as either franked or unfranked dividends. Franked dividends are those treated as being paid out of profits which have borne Australian corporate tax (i.e. to which franking credits have been
allocated) while unfranked dividends are treated as being paid out of untaxed profits. The Australian corporate tax rate is 30%. Franked dividends paid to non-residents are exempt from withholding tax but unfranked (or partly franked) dividends are
subject to withholding tax, generally at 15% on the unfranked amount.

Where income distributed is unfranked, the
distribution would normally be subject to withholding tax, unless the distributions are declared to be conduit foreign income. Broadly conduit foreign income is foreign income and gains that are earned by or through an Australian corporate tax
entity that are exempt from Australian tax on receipt. The conduit foreign income rules provide an exemption from dividend withholding tax on distributions made to non-residents to the extent the amounts are declared to be conduit foreign income. As
Alumina Limited derives conduit foreign income from its overseas investments, when dividends paid to non-resident shareholders are declared to be conduit foreign income, the dividend will not attract withholding tax even if unfranked.

Notices are provided to shareholders which specify the amount (if any) of dividend withholding tax deducted.

In considering whether a company is entitled to pay a dividend, it is the Australian Corporations law which is determinative. A recent
change in the Australian Corporations law has altered the requirements that need to be met. Formerly, a company could only pay a dividend where the company had profits. However, the new legislative amendment has replaced the out of
profits requirement with a three-part test which states that the companys assets must exceed its liabilities, that the company must be able to demonstrate that the dividend would be fair and reasonable to the members as a whole and that
the creditors would not be materially prejudiced.

Despite the amendment to the Australian Corporations law, the Australian
tax legislation has not been similarly updated, and still essentially requires that dividends be paid out of profits. Even though the three-part test under the Corporations law takes precedence, the Australian Taxation Office have outlined a view
that the three-part Corporations law test should be applied in addition to the out of profits test under the tax legislation. However, as this potential inconsistency has yet to be addressed by the Australian courts, there is some uncertainty as to
the exact requirements for paying a dividend at present for Australian taxation purposes, and in identifying whether dividends paid are franked or unfranked dividends.

The current Australian tax rules require taxpayers to hold shares at risk for certain periods before obtaining the benefit of the dividend imputation system. The minimum period for holding
ordinary shares at risk is currently 45 days. Failure to satisfy these requirements may result in the deduction of Australian withholding tax from dividends paid to non-residents of Australia. There is an exemption from these rules for
defined small transactions.

The tax rules classify interests which satisfy a financial arrangements test as
either debt or equity. An interest that is classified as equity will be frankable, whereas an interest that is classified as debt will not be frankable. ADS and ordinary shares are likely to be classified as equity on the basis that the return is
contingent on our performance or at our discretion.

Under the provisions of the Convention between the Government of the
United States of America and the Government of Australia for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income (the Treaty) from July 1 2003 the withholding tax rate on dividends is 5% of the
gross amount of the dividends where the beneficial corporate shareholder entitled to the dividends holds directly at least 10% of the voting power in the company. This rate is reduced to nil in certain circumstances for certain corporate beneficial
shareholders who own at least 80% of the voting shares. For other shareholders the withholding tax rate will be 15% by virtue of the Treaty. As mentioned above, franked dividends will not be subject to withholding tax.

A United States citizen who is resident in Australia, or a United States corporation that is resident in Australia (by reason of carrying
on business in Australia and being managed or controlled in Australia or having its voting power controlled by shareholders who are residents of Australia) holding ADS or ordinary shares as capital assets, may be liable for Australian capital gains
tax (CGT) on the disposal of our ADS or ordinary shares.

ADDITIONAL INFORMATION







In calculating the amount of a capital gain that may be subject to Australian CGT,
special rules apply to individuals, trusts, certain superannuation funds and shareholders of certain listed investment companies. For ADS or ordinary shares acquired after September 21, 1999 and held for at least 12 months, individuals and
trusts will pay tax on half of the gain (calculated in nominal terms) or two-thirds of the gain for certain superannuation funds after allowing for any offsetting capital losses which are applied against the whole nominal gain. For ADS or Ordinary
Shares acquired before that time and held for at least 12 months, individuals, trusts and certain superannuation funds may choose between paying CGT on half of the gain (or two-thirds of the gain for certain superannuation funds), or paying CGT on
all the gain with the gain being calculated on the basis of the cost of the ADS or shares being indexed for inflation up to September 30, 1999. For all types of taxpayers, the legislation freezes the indexation (for inflation) of the cost of
ADS and Ordinary Shares as at September 30, 1999, and abolishes such indexation for ADS and ordinary shares acquired after September 21, 1999.

Under current Australian law, no income or other tax is payable on any profit on disposal of the ADS or ordinary shares held by persons who are residents of the United States within the meaning of the
Treaty except:



| |  |  | if the person (together with associates, if any) held 10% or more (by value) of the issued Alumina Limited shares (including via ADS) at the time of
the disposal or for any continuous 12 month period within the two years preceding the disposal, and the value of such interests is wholly or principally attributed to Taxable Australian Real Property(TARP). Up until the 2013 Federal Budget, TARP
assets were defined as Australian land interests and mining, quarrying and prospecting rights over Australian resources. The Federal Government announced, in the May 2013 Budget a proposed amendment to apply from May 14, 2013 where mining,
quarrying or prospecting information and goodwill connected to the mining right will be valued within the mining rights to which they relate. Effectively this means that mining information and intangibles will count towards the TARP assets of the
entity.

| |  |  | if the ADS or Ordinary Shares have been used by the person in carrying on a trade or business wholly or partly at or through a permanent establishment
in Australia.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

Different rules will apply to persons and corporations which are not residents of the United
States.

Australia does not impose gift, estate or inheritance taxes in relation to gifts of shares or upon the death of a
shareholder.

Australian Good and Services tax (GST)

Neither the issue nor transfer of an ADS or our Ordinary Shares or the payment or receipt of a dividend will give rise to a liability to
goods and services tax in Australia.

Australian Stamp Duty

No Australian stamp duty will be payable on the issue or transfer of an ADS in Alumina Limited or the transfer of our Ordinary Shares in
Alumina Limited.

Minerals Resource Rent Tax (MRRT)

The Australian Federal Government has introduced a Minerals Resource Rent Tax (MRRT), which applies from July 1, 2012. As the MRRT
applies to mined iron ore and coal it does not apply to the minerals (primarily bauxite) that alumina mines. Therefore, it is anticipated that there will be no direct impact on Alumina Limited. In addition, the current Government announced on
October 24, 2013 that it will seek to repeal the MRRT law with effect from July 1, 2014.

Carbon Tax

The Australian Federal Government introduced the carbon pricing scheme, which commenced on July 1, 2012. The scheme
operates in two phases: a fixed (but increasing) carbon permit price which commenced on July 1, 2012 to be followed by a floating price phase from July 1, 2015.

Corporations operating facilities that generate more than 25,000 tonnes of carbon dioxide emissions annually will be required to surrender permits under this regime. The carbon permit price has been fixed
at $23 per tonne in 2012-13, $24.15 in 2013-14 and $25.40 in 2014-15. A cap-and-trade and floor emissions trading scheme is to apply from July 1, 2015 onwards. Originally there was to be a starting floor price of $15 per tonne, however this
plan has since been abandoned. From July 1, 2015, Australian businesses will be able to buy permits from the EU scheme (but EU businesses will not be able to buy Australian permits). At a date no later than July 1, 2018, a full two-way
link will be established, whereby businesses from either jurisdiction will be allowed to buy permits from each other.

Transitional assistance is to be provided under the Jobs and Competitiveness Program in
the three years to 2015. The assistance will be in the form of free permits (reducing by 1.3% per annum) at 94.5% and grants to increase energy efficiency. Assistance is based on an entitys specific activities of which aluminium smelting
is one category which is eligible for assistance.

As part of these measures, there will also be reductions in the fuel tax
credit scheme. The reductions have been fixed from the first three years commencing July 1, 2012 and will move to a flexible price period from July 1, 2015 where fuel tax credits will be determined bi-annually.

However on November 13, 2013 the current Federal Government introduced a series of bills into parliament to repeal the carbon tax
from July 1, 2014. If passed, the proposed legislation will remove the equivalent carbon pricing mechanism from July 1 ,2014. The bills included the following components:

industry assistance provided under the Jobs and Competiveness Program would continue in 2013-2014, but there would be a true
up process for any under or over allocation of free units issued under the Jobs and Competiveness Program

it envisaged
that direct or indirect linking of the carbon pricing scheme with international emissions trading schemes (e.g. EU businesses) will no longer occur and amendments would be to reflect this (e.g. deleting references to prescribed international
units).

United States Federal Income Tax Consequences

The following discussion is a summary of the material United States federal income tax consequences of owning Ordinary Shares or ADS. The
discussion below, except where specifically noted, does not address the effects of any state, local or non-United States tax laws. In addition, it applies to you only if you hold your Ordinary Shares or ADS as a capital asset, and does not address
the tax consequences that may be relevant to you in light of your particular circumstances. Moreover, it does not apply to you if you are not a U.S. person, as defined below, or if you are subject to special treatment under the United States federal
income tax laws, including if you are:



| |  |  | a dealer in securities or currencies
| | - |  | ------------------------------------



| |  |  | a trader in securities if you elect to use a mark-to-market method of accounting for your securities holdings
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | a financial institution
| | - |  | -----------------------



| |  |  | a life insurance company
| | - |  | ------------------------



| |  |  | a tax-exempt organization
| | - |  | -------------------------



| |  |  | a person liable for alternative minimum tax
| | - |  | -------------------------------------------



| |  |  | a person that holds Ordinary Shares or ADS as part of a straddle or a hedging or conversion transaction
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | a person that actually or constructively owns 10% or more of the voting shares of Alumina Limited
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | a person that purchases or sells shares or ADSs as part of a wash sale for tax purposes
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | a person whose functional currency is not the United States dollar.
| | - |  | ---------------------------------------------------------------------

This discussion is based on the Internal Revenue Code of 1986, as amended (the Code), its legislative history, existing and proposed
regulations, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. In addition, this section is based in part upon the representations of the Depositary and the
assumption that each obligation in the deposit agreement and any related agreement will be performed in accordance with its terms.

If a partnership holds Ordinary Shares or ADSs, the United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A
partner in a partnership holding the Ordinary Shares or ADSs should consult its tax advisor with regard to the United States federal income tax treatment of an investment in the Ordinary Shares or ADS.

You are a U.S. holder if you are a beneficial owner of shares or ADSs and you are:



| |  |  | a citizen or resident of the United States
| | - |  | ------------------------------------------

| |  |  | a corporation created or organized in the United States or under the law of the United States or any state of the United States
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate, the income of which is subject to United States federal income taxation regardless of its source
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | a trust if a United States court can exercise primary supervision over the trusts administration and one or more United States persons are
authorized to control all substantial decisions of the trust.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The tax consequences to you of the ownership
of Ordinary Shares or ADS will depend upon the facts of your particular situation. We encourage you to consult your own tax advisors with regard to the application of the federal income tax laws, as well as to the applicability and effect of any
state, local or foreign tax laws or other tax consequences of owning and disposing of shares and ADSs in your particular circumstances.

In general, and taking into account the earlier assumptions, for United States federal income tax purposes, if you hold ADS, you will be treated as the owner of the Ordinary Shares represented by those
ADS. Exchanges of Ordinary Shares for ADS, and ADS for Ordinary Shares, generally will not be subject to United States federal income tax.

Distributions

Subject to the passive foreign investment company rules
discussed below, distributions made to you on or with respect to Ordinary Shares or ADS will be treated as dividends and will be taxable as ordinary income to the extent that those distributions are made out of our current or accumulated earnings
and profits as determined for United States federal income tax purposes. You must include the gross amount of the dividend payment (including, in the case of unfranked or partially unfranked dividends, any Australian tax withheld) as income at the
time you receive it, actually or constructively. To the extent that a distribution exceeds our current or accumulated earnings and profits for a taxable year, the excess will be treated as a tax-free return of capital which reduces your tax basis in
the Ordinary Shares or ADS to the extent of the tax basis, and any remaining amount will be treated as capital gain. You generally will not be entitled to claim any dividends received deduction generally allowed to U.S. corporations with respect to
distributions paid with respect to your Ordinary Shares or ADS. The amount of the dividend distribution that you must include in your income will be the US dollar value of the dividend distribution.

Certain qualifying dividend distributions are taxable to non-corporate U.S. Holders at preferential rates applicable to long-term capital
gains. Alumina Limited believes that the dividends on ADS will qualify for these preferential rates if the taxpayer meets the required holding period. In order for the dividends on the ADS to qualify, taxpayers must hold the ADS for at least 61 days
during the 121 day period beginning 60 days before the ex-dividend date. In order for dividends paid by foreign corporations to qualify for the preferential rates, the foreign corporation must meet certain requirements, including that it not be
classified as a passive foreign investment company for United States federal income tax purposes in either the taxable year of the distribution or the preceding taxable year. As discussed further below, Alumina Limited believes that its Ordinary
Shares or ADS will not be treated as shares of a passive foreign investment company, but this conclusion is a factual determination that is made annually and thus may be subject to change.

Dividends paid to U.S. holders with respect to our Ordinary Shares or ADS and that are unfranked or partially unfranked are subject to
Australian withholding tax at a maximum rate of 15% with respect to the unfranked portion of the dividend payment. Subject to certain limitations, the Australian tax withheld in accordance with the Treaty and paid over to Australia generally will be
creditable against your United States federal income tax liability.

Dividends will be income from sources outside the United
States, and will, depending on your circumstances, be either passive income or general income for purposes of computing the foreign tax credit allowable to you. Special rules apply in determining the foreign tax credit
limitation with respect to dividends that are subject to the preferential rates.

Disposition

Subject to the passive foreign investment company rules discussed below, any gain or loss you realize on the sale, exchange or other
taxable disposition of Ordinary Shares or ADS will be subject to United States federal income taxation as a capital gain or loss in an amount equal to the difference between the US dollar value of the amount that you realize on that sale, exchange
or other disposition and your adjusted tax basis, determined in US dollars, in the Ordinary Shares or ADS surrendered. The gain or loss will be long term capital gain or loss if your holding period for the Ordinary Shares or ADS is more than one
year. A non-corporate U.S. person is generally taxed at preferential rates

on long term capital gain as described above for qualifying dividend distributions. Any capital gain or loss so realized will generally be United States source gain or loss for foreign tax credit
limitation purposes. Your ability to deduct capital losses is subject to limitations.

Additional Tax on Net Investment
Income

For taxable years beginning after December 31, 2012, a U.S. holder that is an individual or estate, or a trust
that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the U.S. holders net investment income for the relevant taxable year and (2) the excess of the
U.S. holders modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals is between US$125,000 and US$250,000 depending on the individuals circumstances). A holders net investment
income will generally include its dividend distribution income and its net gains from the disposition of Ordinary Shares or ADSs, unless such dividend distribution income or net gains are derived in the ordinary course of the conduct of a trade or
business (other than a trade or business that consists of certain passive or trading activities). If you are a U.S. holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of this
additional tax on net investment income to your income and gains in respect of your investment in Ordinary Shares or ADS.

Passive Foreign Investment Company Rules

Alumina Limited believes that its Ordinary Shares or ADS will not be treated as shares of a passive foreign investment company, or PFIC, for United States federal income tax purposes, but this
conclusion is a factual determination that is made annually and thus may be subject to change.

In general, if you are a U.S.
holder, we will be a PFIC with respect to you if for any taxable year in which you held our ADS or Ordinary Shares:



| |  |  | at least 75% of our gross income for the taxable year is passive income or
| | - |  | --------------------------------------------------------------------------



| |  |  | at least 50% of the value, determined on the basis of a quarterly average, of our assets is attributable to assets that produce or are held for the
production of passive income.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Passive income generally includes dividends, interest, royalties, rents
(other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains from assets that produce passive income. If a foreign corporation owns at least 25% by value of the shares of another corporation, the
foreign corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation, and as receiving directly its proportionate share of the other corporations income.

If the company is treated as a PFIC, and you are a U.S. holder that did not make a qualified electing fund QEF or a
mark-to-market election, as described below, you will be subject to special rules with respect to:



| |  |  | any gain you realize on the sale or other disposition of your Ordinary Shares or ADS; and
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | any excess distribution that the company makes to you (generally, any distributions to you during a single taxable year that are greater than 125% of
the average annual distributions received by you in respect of the Ordinary Shares or ADS during the three preceding taxable years or, if shorter, your holding period for the Ordinary Shares or ADS).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under these rules:



| |  |  | the gain or excess distribution will be allocated rateably over your holding period for the Ordinary Shares or ADS;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the taxable year in which you realized the gain or excess distribution will be taxed as ordinary income;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each prior year, with certain exceptions, will be taxed at the highest tax rate in effect for that year; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the interest charge generally applicable to underpayments of tax will be imposed in respect of the tax attributable to each such year.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Special rules apply for calculating the amount of the foreign tax credit with respect to excess
distributions by a PFIC.

ADDITIONAL INFORMATION







If you are a U.S. holder and own Ordinary Shares or ADS in a PFIC and you make a QEF
election for the first tax year in which your holding period of PFIC shares begin, generally you will not be subject to the default rules discussed above. However, if you make this QEF election, you will be subject to the U.S. federal income tax on
your pro rata share of (a) the net capital gain of the PFIC, which will be taxed as long term capital gain, and (b) the ordinary earnings of the PFIC, which will be taxed as ordinary income. If you make a QEF election you will be subject
to U.S. federal income tax on such amounts for each tax year in which the company is a PFIC, regardless of whether such amounts are actually distributed to you. If you make a QEF election and have an income inclusion, you may, subject to certain
limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge.

If you
have made a QEF election generally (a) you may receive a tax free distribution from the PFIC to the extent that such distribution represents earnings and profits that were previously included in your income because of such QEF
election and (b) you will adjust your tax basis in the PFIC shares to reflect the amount included in income or allowed as a tax free distribution because of such QEF election. In addition, if a QEF election is in effect for all the years the
company is a PFIC, generally you will recognize capital gain or loss on the sale or other taxable disposition of the PFIC shares.

If you own Ordinary Shares or ADS in a PFIC that are treated as marketable shares, you may also make a mark-to-market election. If you make this election, you will not be subject to the PFIC rules
described above. Instead, in general, you will include as ordinary income each year the excess, if any, of the fair market value of your Ordinary Shares or ADS at the end of the taxable year over your adjusted basis in your Ordinary Shares or ADS.
These amounts of ordinary income will not be eligible for the favorable tax rates applicable to qualified dividend income or long-term capital gains. You will also be allowed to take an ordinary loss in respect of the excess, if any, of the adjusted
basis of your Ordinary Shares or ADS over their fair market value at the end of the taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). Your basis in the Ordinary Shares
or ADS will be adjusted to reflect any such income or loss amounts.

Your Ordinary shares or ADSs will be treated as stock in
a PFIC if we were a PFIC at any time during your holding period in the ordinary shares or ADSs, even if we are not currently a PFIC. For purposes of this rule, if you make a mark-to-market election with respect to your shares or ADSs, you will be
treated as having a new holding period in your shares or ADSs beginning on the first day of the first taxable year beginning after the last taxable year for which the mark-to-market election applies.

In addition, notwithstanding any election you make with regard to the shares or ADSs, dividends that you receive from us will not
constitute qualified dividend income to you if we are a PFIC either in the taxable year of the distribution or the preceding taxable year. Dividends that you receive that do not constitute qualified dividend income are not eligible for taxation at
the preferential rates applicable to qualified dividend income. Instead, you must include the gross amount of any such dividend paid by us out of our accumulated earnings and profits (as determined for United States federal income tax purposes) in
your gross income, and it will be subject to tax rates applicable to ordinary income.

If you own Ordinary Shares or ADS
during any year that we are a PFIC, you must file Internal Revenue Service Form 8621.

Information With Respect to Foreign
Financial Assets

Owners of specified foreign financial assets with an aggregate value in excess of $50,000
(and in some circumstances, a higher threshold) may be required to file an information report with respect to such assets with their tax returns. Specified foreign financial assets include any financial accounts maintained by foreign
financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons (such as your Ordinary Shares or ADSs),
(ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties, and (iii) interests in foreign entities. U.S. Holders are urged to consult their tax advisors regarding the application of this
reporting requirement to their ownership of Ordinary Shares or ADSs.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK







|ITEM 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

A. Quantitative Information about Market Risk

Continuing
operations

Alumina Limiteds policy is generally not to hedge its commodity or currency exposure other than to secure
the US dollar value of dividend payments and foreign currency borrowings. This policy is reviewed periodically. AWAC has previously sought to manage its exposure to both the aluminium price and exchange rates through the use of derivative products.
AWAC anticipates the continued requirement to sell alumina and aluminium and purchase other commodities, such as natural gas and fuel oil, for its operations. In 2012, AWAC entered in to option collar contracts for some of the gas requirements for
the Point Comfort refinery over the period from April 2012 to December 2014. These option contracts have since been extended to cover the period to December 2015. AWAC is also subject to exposure from fluctuations in foreign currency exchange rates.
Foreign exchange contracts may be used from time to time to hedge the variability in cash flows from the forecasted payment or receipt of currencies other than the functional currency.

The Group is exposed to commodity price risk through its investment in AWAC. AWAC manages commodity price risk through long-term purchase
contracts for some input costs. Some energy price risk is managed through short-term commodity hedges.

Exchange Rate
Risk

Foreign currency risk relates to Alumina Limiteds exposure to changes in exchange rates. AWACs
revenue streams are significantly derived from the sale of its commodity production in US dollars. AWACs Australian operations declare dividends payable to Alumina Limited in Australian dollars and the amount of US dollar revenue Alumina
Limited receives fluctuates with the moving AUD/USD exchange rate.

Alumina Limiteds 2014 earnings sensitivities, based
on 2013 earnings and 2013 average A$/US$ exchange rates is that each one cent movement in the average Australian dollar/US dollar exchange rate is expected to impact earnings by approximately $12 million before tax.

Further sensitivity analysis in relation to exchange rate risk can be found in Note 2 to the Financial Report on page F-16.

Interest rate risk

Interest rate risk refers to Alumina Limiteds exposure to movements in interest rates. Alumina Limited is primarily exposed to interest rate risk on its outstanding interest bearing liabilities,
primarily determined by US$ interest rates. As the interest rates fluctuate, the amount of interest payable on debt balances where the interest rate is not fixed will also fluctuate. Sensitivity analysis in relation to interest rate risk can be
found in Note 2 to the Financial Report on page F-16.

Funding facilities were restructured during 2013 and 2012, to provide
greater diversity of funding sources, smaller annual refinancing requirements and to extend the companys maturity profile.

As at December 31, 2013, the Alumina Group had short term bank debt outstanding totaling $50.6 million and long term debt outstanding totaled $108.6 million.

As at December 31, 2012, the Alumina Group had short term bank debt outstanding totaling $52.0 million and long term debt
outstanding totaled $622.5 million.

As at December 31, 2013, Alumina Limited and its subsidiaries had no outstanding hedge contracts
over future sales of alumina or aluminium.

Interest rate and cross-currency swaps

As part of the BNDES financing, Alumina Limited had Cross Currency Interest Rate Swaps (CCIRS) during 2013 and 2012 for the whole amount of the BRL denominated tranche to manage the exposure to BRL
interest rates over the life of the loan. Alumina Limited used CCIRS during 2009 to manage the interest rate swap exposure between EUR and AUD on EUR denominated assets.

As at December 31, 2013 the only cross-currency swaps in place were in relation to the BNDES financing.

B. Qualitative Information About Market Risk

Qualitative
information on price risk management, and commodity and currency hedging, is included in the discussion above in Item 11 Quantitative Information on Price Risk Management. Qualitative information on treasury management and exchange

|ITEM 15. | CONTROLS AND PROCEDURES
|-------- | -----------------------

A. Disclosure Controls and Procedures

Under the supervision and
with the participation of Alumina Limiteds Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of the effectiveness of Alumina Limiteds disclosure controls and procedures (as such term is defined in
Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of December 31, 2013. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our
disclosure controls and procedures are effective as at December 31, 2013, in ensuring that material information required to be disclosed in this annual report is recorded, processed, summarized and reported to them for assessment, and required
disclosure is made within the time period specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to Alumina Limiteds management, as appropriate to allow timely
decisions regarding disclosure.

B. Managements Annual Report on Internal Control Over Financial Reporting

Alumina Limiteds management is responsible for establishing and maintaining adequate internal control over
financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Alumina Limiteds internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

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 policies or procedures may deteriorate.

Alumina Limiteds management under the supervision of and with the participation of the Chief Executive Officer and Chief Financial Officer has evaluated the effectiveness of its internal control
over financial reporting based on the criteria in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, our management has concluded that
Alumina Limiteds internal control over financial reporting was effective as of December 31, 2013.

C.
Attestation Report of the Registered Public Accounting Firm

Alumina Limiteds internal control over financial
reporting as of December 31, 2013 has been audited by PricewaterhouseCoopers, an independent registered public accounting firm, as stated in their report which appears on page F-38 herein.

D. Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the year ended December 31, 2013 that
have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

|ITEM 16A. | AUDIT COMMITTEE FINANCIAL EXPERT
|--------- | --------------------------------

The board has determined that as from January 1, 2014, Mr Peter Day is an audit committee financial expert as required by the New York Stock Exchange listing standards. Mr Peter
Wasow was previously considered an audit committee financial expert until he relinquished his membership of the Audit Committee on November 27, 2013. Mr Day is considered independent under the independence requirements of the New
York Stock Exchange corporate governance standards. Although the board of directors has determined that Mr Day has the requisite attributes defined under the rules of the Securities and Exchange Commission, his responsibilities are the same as those
of the other audit committee members. He is not an auditor or accountant, does not perform field work and is not a full-time employee. The SEC has determined that an audit committee member who is designated as an audit committee
financial expert will not be deemed to be an expert for any purpose as a result of being identified as an audit committee financial expert. The audit committee is responsible for oversight of management in the preparation of our
financial statements and financial disclosures. The audit committee relies on the information provided by management and the independent auditors. The audit committee does not have the duty to plan or conduct audits. A copy of our Audit Committee
Charter is available from our web site at www.aluminalimited.com. This link is an inactive textual link for reference only.



|ITEM 16B. | CODE OF ETHICS
|--------- | --------------

Alumina Limited has established overarching values that form the ethical framework for the Companys Code of Conduct. The Code of Conduct drives the way in which Alumina Limited conducts its business
and behavior. The Code of Conduct was developed by aligning the Companys agreed core values with best practice corporate governance models. The Code applies to all directors, employees and contractors. The Code of Conduct is reviewed regularly
to ensure it is relevant and accurately reflects best practice principles.

This Code of Conduct is available from our web
site at www.aluminalimited.com. This link is an inactive textual link for reference only. Alumina Limited will provide any person without charge, upon request, a copy of the Code of Conduct. Copies of the Code can be requested by contacting Colin

Audit Fees

The aggregate fees billed in each of the last two fiscal years for professional services rendered by the principal accountant for the audit of the annual financial statements or services that are normally
provided by the accountant in connection with statutory and regulatory filing engagements for 2013 and 2012 are approximately $726,000 and $865,000 respectively.

Audit Related Fees

The aggregate fees billed in each of the last two
fiscal years for products and services provided by the principal accountant, other than the services reported under Audit Fees and Tax Fees are approximately $116,000 in 2013 and $4,000 in 2012. The nature of services comprising the fees disclosed
under this category is related to Capital Market Services, International Financial Reporting Standards and other sundry agreed upon procedure engagements.

Tax Fees

The aggregate fees billed in each of the last two fiscal years
for tax services by the principal accountant that are not related to the performance of the audit or review of Alumina Limiteds financial statements and are not reported under Audit Fees are approximately $16,000 in both 2013 and 2012. The
nature of services comprising the fees disclosed under this category is for tax compliance work in relation to Alumina Limiteds subsidiaries incorporated in the UK.

Pre-Approval Policies

The policy Alumina Limited has adopted for
pre-approval of non-audit services to be performed by our independent registered public accounting firm, PricewaterhouseCoopers (PwC) is as follows:

PwC services which have fees of up to A$100,000 shall require the prior approval of the Audit Committee Chairman. Such approval shall include the scope of the services and the approximate amount of fees,
and shall be reported to the next Audit Committee meeting;

For PwC services of more than A$100,000 and less than A$250,000,
the provision of such services requires the prior approval of the Audit Committee;

For PwC services of more than A$250,000,
unless PwC skills and experience are integral to the services (in which case the provision of such services requires the prior approval of the Audit Committee), the proposed services are to be put to competitive tender with the requirement for CFO,
CEO and Audit Committee Chairmans approval of the inclusion of PwC in tender list. The awarding of a contract, following a competitive tender, to PwC for the provision of these services also requires the prior approval of the Audit Committee.

|ITEM 16G. | CORPORATE GOVERNANCE
|--------- | --------------------

The NYSE Listing Rules, Section 303A, have a broad regime of corporate governance requirements for NYSE-listed companies. Under the NYSE Listing Rules foreign private issuers, such as Alumina
Limited, are permitted to follow home country practice in lieu of the requirements of Section 303A, except for the Listing Rule relating to compliance with Rule 10A-3 of the Securities Exchange Act of 1934 and certain notification provisions
contained in Section 303A of the Listing Rules. Section 303A.11 of the Listing Rules, however, requires us to disclose any significant ways in which our corporate governance practices differ from those followed by U.S. companies under NYSE
Listing Rules. We have compared our corporate governance practices to the requirements of the Section 303A of the NYSE Listing Rules that would otherwise currently apply to foreign private issuers and note the following significant differences:



| |  |  | Our Nomination Committee Charter does not include the mandate to develop and recommend to the Board a set of corporate governance principles applicable
to the corporation (which is largely a Board function).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Nomination Committee charter does not include the mandate to oversee the evaluation of the Board and management. The Board undertakes a self
evaluation, non-executive directors evaluate the Chief Executive Officer, and the Chief Executive Officer evaluates other management.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Shareholders are not provided the opportunity to vote on certain new equity compensation plans or material revisions to existing equity compensation
plans, such as the Companys Employee Share Plan, which involves the purchase of shares on market by the Trustee of the Plan.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have not published a set of corporate governance guidelines as set forth in Section 303A.09. However, we do provide information on corporate
governance policies and practices as required by Australian Stock Exchange rules, which are available in our annual report and on the website.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our Director independence standard related to direct compensation from Alumina Limited differs from the standard set for the Section 303A.02. Our
threshold for direct compensation in a twelve month period is A$250,000 whereas Section 303A.02 currently has a threshold of US$100,000.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Compensation Committee does not follow the procedures for retaining advisors that will come into force on July 1, 2013 under
Section 303A.05(c).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Compensation and Nomination Committee is not composed entirely of independent directors. The Compensation and Nomination Committee members include
Mr Cheng Zeng, who is not an independent director.

ALUMINA LIMITED

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED 31 DECEMBER 2013, 2012 AND 2011

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The principal accounting policies adopted in the preparation of these consolidated financial statements are set out below. These policies
have been consistently applied to all the years presented, unless otherwise stated. These consolidated financial statements are for the Group consisting of Alumina Limited and its subsidiaries (together referred to as the Group).

A BASIS OF PREPARATION

These general purpose financial statements for the years ended 31 December 2013, 2012 and 2011 have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by
the International Accounting Standards Board. Alumina Limited is a for-profit entity for the purpose of preparing the financial statements.

(i) Historical cost convention

These financial statements have been
prepared under the historical cost convention, as modified by the revaluation of certain financial assets and liabilities (including derivative instruments) at fair value through profit and loss.

(ii) Critical accounting estimates

The preparation of financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Groups
accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the financial statements are disclosed in Note 3.

(iii) Change in accounting policy

The adoption of the revised IAS 19Employee Benefits resulted in two changes to the entitys accounting policy which affected items recognised in the financial statements:



| |  |  | Recognition of actuarial gains and losses (re-measurements). Actuarial gains and losses are renamed re-measurements and
will be recognised immediately in other comprehensive income. Re-measurements recognised in other comprehensive income will not be recycled through profit or loss in subsequent periods. The revised standard does not mandate where re-measurements
must be presented in equity. Alumina Limited has previously chosen to recognise actuarial gains and losses in profit or loss. On adoption of the revised standard, Alumina Limited has recognised re-measurements in other comprehensive income and these
re-measurements continue to be presented in retained earnings.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Measurement of pension expense. Annual expense for a funded benefit plan will include net interest expense or income, calculated by applying the
discount rate to the net defined benefit asset or liability. This will replace the finance charge and expected return on plan assets. There will be no change in the discount rate, which remains a high quality corporate bond rate where there is a
deep market in such bonds, and a government bond rate in other markets.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The revised standard is applied
retrospectively. Adjustments to the retirement benefits obligations have been recognised in the consolidated statement of profit or loss and other comprehensive income for the prior period as outlined in the table below. There is no change to the
amounts previously recognised in the consolidated balance sheet.



|                                                                                        |  |                                       |               |   |                                |  |               |                                                  |  |  |               |

The revised standard has also changed the accounting policy for the Groups annual leave obligations. As the Company
expects all annual leave to be taken within 12 months of the respective service being provided, annual leave obligations are classified as short term employee benefits in their entirety. Therefore, the change had no impact on the financial
statements

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)

FOR THE YEARS ENDED 31 DECEMBER 2013, 2012 AND 2011



1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)



B PRINCIPLES OF CONSOLIDATION

(i) Subsidiaries

The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of Alumina Limited as at 31 December 2013 and 2012 and the results of all subsidiaries for the years
ended December 31, 2013, 2012 and 2011. Alumina Limited and its subsidiaries together are referred to in this financial report as the Group or the consolidated entity.

Subsidiaries are all entities (including structured entities) over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its
involvement within the entity and has an ability to affect those returns through its power to direct the activities of the entity.

Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are de-consolidated from the date that control ceases.

The acquisition method of accounting is used to account for the acquisition of subsidiaries by the Group.

Intercompany transactions, balances and unrealised gains on transactions between Group companies are eliminated. Unrealised losses are
also eliminated unless the transaction provides evidence of the impairment of the asset transferred.

Non-controlling interests
in the results and equity of subsidiaries are shown separately in the consolidated statement of profit or loss and other comprehensive income, statement of changes in equity and balance sheet respectively.

(ii) Associates

Associates are those entities over which the consolidated entity has significant influence but not control or joint control, generally accompanying a shareholding of between 20 per cent and
50 per cent of the voting rights. Investments in associates are accounted for using the equity method of accounting, after initially being recognised at cost. The consolidated entitys investment in associates includes goodwill identified
on acquisition.

The Groups share of its associates post acquisition profits or losses is recognised in the profit
or loss, and its share of post-acquisition other comprehensive income is recognised in other comprehensive income. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. Dividends receivable from
associates reduce the carrying amount of the investment.

When the Groups share of losses in an associate equals or
exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate.

Unrealised gains on transactions between the Group and its associates are eliminated to the extent of the Groups interest in the
associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted
by the Group.

(iii) Employee Share Trust

The Group has formed a trust to administer the Groups employee share scheme. This trust is consolidated, as the substance of the relationship is that the trust is controlled by the Group.

Shares held by the Alumina Employee Share Plan Trust are disclosed as treasury shares and deducted from contributed equity.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)



C INCOME TAX

The income tax expense or revenue for the period is the tax payable on the current periods taxable income based on the applicable
income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and to unused tax losses.

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the reporting period in the countries where the Companys subsidiaries and associates
operate and generate taxable income.

Deferred income tax is provided in full, using the liability method, on temporary
differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, the deferred income tax is not accounted for if it arises from initial recognition of an asset or
liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or
substantially enacted by the reporting date and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled.

Deferred tax assets are recognised for deductible temporary differences and unused tax losses only if it is probable that future taxable amounts will be available to utilise those temporary differences
and losses.

Deferred tax liabilities and assets are not recognised for temporary differences between the carrying amount and
tax bases of investments in controlled entities where the parent entity is able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and
when the deferred tax balances relate to the same taxation authority. Current tax assets and liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realise the asset and
settle the liability simultaneously.

Alumina Limited and its wholly-owned Australian controlled entities have implemented the
tax consolidation legislation. As a consequence, these entities are taxed as a single entity and the deferred tax assets and liabilities of these entities are set off in the consolidated financial statements.

Current and deferred tax balances attributable to amounts recognised directly in other comprehensive income and equity are also recognised
directly in other comprehensive income and equity.

Additional withholding taxes that arise from the distribution of dividends
are recognised at the same time as the liability to pay the related dividend.

Tax consolidation legislation

Alumina Limited and its wholly-owned Australian controlled entities have implemented tax consolidation legislation.

The head entity, Alumina Limited, and the controlled entities in the tax consolidated Group account for their own current and
deferred tax amounts. These tax amounts are measured as if each entity in the tax consolidated Group continues to be a standalone entity in its own right. These tax amounts are measured using the separate tax payer within the Group approach.

In addition to its own current and deferred tax amounts, Alumina Limited also recognises the current tax liabilities (or
assets) and the deferred tax assets arising from unused tax losses and unused tax credits assumed from controlled entities in the tax consolidated Group.

The entities have also entered into a tax funding agreement under which the wholly-owned entities fully compensate Alumina Limited for any current tax payable assumed and are compensated by Alumina
Limited for any current tax receivable and deferred tax assets relating to unused tax losses or unused tax credits that are transferred to Alumina Limited under the tax consolidation legislation. The funding amounts are determined by reference to
the amounts recognised in the wholly-owned entities financial statements.

The amounts receivable/payable under the tax
funding agreement are due upon receipt of the funding advice from the head entity, which is issued as soon as practicable after the end of each financial year. The head entity may also require payment of interim funding amounts to assist with its
obligations to pay tax instalments.

Assets or liabilities arising under tax funding agreements within the consolidated
entities are recognised as current amounts receivable or payable to other entities in the Group.

Any difference between the
amounts assumed and amounts receivable or payable under the tax funding agreement are recognised as a contribution to (or distribution from) wholly-owned tax consolidated entities.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)



D FOREIGN CURRENCY TRANSLATION

(i) Functional and presentation currency

Items included in the financial statements of each of the Groups entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency).
The consolidated financial statements are presented in US dollars, which is Alumina Limiteds presentation currency and functional currency.

(ii) Transactions and balances

Foreign currency transactions are
translated into functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year end exchange rates of
monetary assets and liabilities denominated in foreign currencies are recognised in the profit or loss, except when they are deferred in other equity as qualifying cash flow hedges and qualifying net investment hedges or are attributable to part of
the net investment in a foreign operation.

(iii) Controlled foreign entities and associates

The results and financial position of all the Group entities and associates that have a functional currency different from the
presentation currency are translated into the presentation currency as follows:



| |  |  | assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | income and expenses are translated at average exchange rates (unless this is not a reasonable approximation of the cumulative effect of the rates
prevailing on the transaction dates, in which case income and expenses are translated at the dates of the transactions)
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all resulting exchange differences are recognised in other comprehensive income.
| | - |  | --------------------------------------------------------------------------------

On consolidation, exchange differences arising from the translation of any net investment in foreign entities, and of borrowings and other
financial instruments designated as hedges of such investments, are recognised in other comprehensive income. When a foreign operation is sold, a proportionate share of such exchange differences are reclassified to the profit or loss, as part of the
gain or loss on sale.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets
and liabilities of the foreign entity and translated at the closing rate.

E PROPERTY, PLANT AND EQUIPMENT

(i) Owned Assets

Items of property, plant and equipment are stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributable to the acquisition of the items.

(ii) Leased Assets

The Group leases office facilities under an operating lease agreement. Payments made under this agreement are recognised in the profit or loss on a straight-line basis over the term of the lease. Lease
incentives received are recognised in the profit or loss as an integral part of the total lease expense over the term of the lease.

F RECEIVABLES

All trade debtors are recognised initially at fair
value and subsequently measured at amortised cost, less provision for impairment. Collectability of trade debtors is reviewed on an ongoing basis. Debts which are known to be uncollectible are written off by reducing the carrying amount directly. An
allowance account (provision for impairment of trade receivables) is used when there is objective evidence that the Group will not be able to collect all amounts due according to the original terms of the receivables. The amount of the impairment
allowance is the difference between the assets carrying amount and the present value of estimated future cash flows, discounted at the original effective interest rate. The amount of the impairment loss is recognised in the profit or loss
within other expenses. When a trade receivable for which an impairment allowance had been recognised becomes uncollectible in a subsequent period, it is written off against the allowance account. Subsequent recoveries of amounts previously written
off are credited against other expenses in the profit or loss.

G CASH AND CASH EQUIVALENTS

Cash and cash equivalents comprise cash on hand, deposits held at call with financial institutions, other short-term, highly liquid
investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and bank overdrafts.

H IMPAIRMENT OF ASSETS

The Group assesses at each reporting period whether there is objective evidence that the investment in associates is impaired. An impairment loss is recognised for the amount by which the assets
carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an assets fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there
are separately identifiable cash flows (cash generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at the end of each reporting period.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)



I BUSINESS COMBINATIONS

The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other
assets are acquired. The consideration transferred for the acquisition of a subsidiary comprises the fair values of the assets transferred, the liabilities incurred and the equity interests by the group. The consideration transferred also includes
the fair value of any asset or liability resulting from a contingent consideration arrangement and the fair value of any pre-existing equity interest in the subsidiary. Acquisition-related costs are expensed as incurred. Identifiable assets acquired
and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the Group recognises any
non-controlling interest in the acquiree either at fair value or at the non-controlling interests proportionate share of the acquirees net identifiable assets.

The excess of the consideration transferred and the amount of any non-controlling interest in the acquiree over the fair value of the net identifiable assets acquired is recorded as goodwill. If those
amounts are less than the fair value of the net identifiable assets of the subsidiary acquired and the measurement of all amounts has been reviewed, the difference is recognised directly in profit or loss as a bargain purchase.

Where settlement of any part of cash consideration is deferred, the amounts payable in the future are discounted to their present value as
at the date of exchange. The discount rate used is the entitys incremental borrowing rate, being the rate at which a similar borrowing could be obtained from an independent financier under comparable terms and conditions.

Contingent consideration is classified either as equity or a financial liability. Amounts classified as a financial liability are
subsequently remeasured to fair value with changes in fair value recognised in profit or loss.

J DEPRECIATION OF
PROPERTY, PLANT AND EQUIPMENT

Depreciation is calculated on a straight line basis to allocate the cost of each item of
property, plant and equipment (excluding land and investment properties) over its expected useful life to the consolidated entity.

Borrowings are initially recognised at fair value, net of transaction costs incurred. Borrowings are subsequently measured at amortised cost. Any difference between the proceeds (net of transaction costs)
and the redemption amount is recognised in profit or loss over the period of the borrowings using the effective interest method.

Fees paid on establishment of loan facilities are recognised as transaction costs of the loan to the extent that it is probable that some
or all of the facility will be drawn down. In this case, the fee is deferred until the draw down occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a
prepayment for the liquidity services and amortised over the period of the facility to which it relates.

Borrowings are
classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.

L BORROWING COSTS

Borrowing costs comprise interest payable on
borrowings calculated using the effective interest rate method and amortisation of capital facility fees. Borrowing costs incurred for the construction of any qualifying asset are capitalised during the time that it is required to complete and
prepare the asset for its intended use or sale. Other borrowing costs are expensed.

M TRADE AND OTHER PAYABLES

These amounts represent liabilities for goods and services provided to the Group prior to the end of the financial
year and which are unpaid. These amounts are unsecured and are usually paid within thirty days of recognition.

N
REVENUE

Interest income is recognised using the effective interest method. Dividend income is recognised in the profit
or loss on the date the Groups right to receive payments is established.

O EMPLOYEE BENEFITS

(i) Salaries and annual leave

Liabilities for salaries and annual leave are recognised in current provisions (i.e. short-term employee benefits), and are measured as the amount unpaid at reporting date at expected pay rates in respect
of employees services up to that date, including related on-costs.

(ii) Long
service leave

The liability for long service leave is recognised in the provision for employee benefits and measured as
the present value of expected future payments to be made in respect of services provided by employees up to the reporting date. Consideration is given to expected future wage and salary levels, experience of employee departures and period of
service. Expected future payments are discounted using market yields at the reporting date on national government bonds with terms to maturity and currency that match, as closely as possible, the estimated future cash flows.

(iii) Share-based payments

Share-based compensation benefits are provided to employees via the Alumina Employee Share Plan. Information relating to these schemes is set out in Note 18.

The fair value of performance rights granted under the Alumina Employee Share Plan is recognised as an employee benefit expense with a
corresponding increase in equity. The fair value is measured at grant date and recognised over the period during which the employees become unconditionally entitled to the performance rights.

The fair value at grant date is determined using a methodology which employs the Monte Carlo simulation and a Black-Scholes option pricing
model. This methodology takes into account the exercise price, the term of the performance right, the vesting and performance criteria, the impact of dilution, the non-tradeable nature of the performance right, the share price at grant date and
expected price volatility of the underlying share, the expected dividend yield and the risk-free interest rate for the term of the performance right.

Upon the exercise of performance rights, the balance of the share-based payments reserve relating to those performance rights is transferred to share capital.

Non-market vesting conditions are included in assumptions about the number of performance rights that are expected to become exercisable.
At each balance sheet date, the entity revises its estimate of the number of performance rights that are expected to become exercisable. The employee benefit expense recognised each period takes into account the most recent estimate. The impact of
the revision to original estimates, if any, is recognised in the profit or loss with a corresponding adjustment to equity.

(iv) Superannuation

From 27 July 2001 until May 2012, all employer contributions and ongoing management of employees superannuation entitlements were managed by the WMC Superannuation Plan, an independently
managed sub-plan of the Plum Superannuation Fund, except where the relevant employees elected for those contributions to be paid to an alternate fund. Since May 2012, Alumina employees are members of an Alumina Limited Super Plan managed by MLC
MasterKey Super, except for employees who elected to contribute to an alternate fund. The plan is an accumulation category plan which offers a minimum Company contribution (subject to certain cashing out options and legislation) of 9.25 per
cent of basic salary to each members account. Members also have the option to make voluntary contributions to their account. Employer contributions to these funds are recognised as an expense.

(v) AWAC (Alcoa World Alumina and Chemicals)- Defined Benefit Plans

Alumina Limiteds associates have defined benefit plans in place. The associates net obligation in respect of defined benefit
plans, is calculated separately for each plan by estimating the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value, and the fair
value of any plan assets is deducted.

The discount rate is the yield at the balance sheet date on a combination of government
and corporate bonds that have maturity dates approximating the terms of the associated entitys obligations. The calculation is performed by a qualified actuary using the projected unit credit method.

Re-measurement gains and losses arising from experience adjustments and changes in actuarial assumptions are recognised in the period in
which they occur, directly in other comprehensive income. They are included in retained earnings in the statement of changes in equity and in the balance sheet.

P DERIVATIVES

Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently remeasured to
their fair value at each reporting date. The method of recognising a gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.

(i) Derivatives that do not qualify for hedge accounting

Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognised immediately in profit
or loss.

(ii) Derivatives that are designated in hedge relationships

The Group documents at the inception of the hedging transaction the relationship between hedging instruments and hedged items, as well as
its risk management objective and strategy for undertaking various hedge transactions. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions have
been and will continue to be highly effective in offsetting changes in fair values or cash flows of hedged items.

(iii)
Net investment in a foreign operations hedge

The portion of a gain or loss on an instrument used to hedge a net investment
in a foreign operation that is determined to be an effective hedge is recognised directly in other comprehensive income. The ineffective portion is recognised immediately in profit or loss. The gain or loss on hedging instruments relating to the
effective portion of the hedge that has been recognised directly in other comprehensive income shall be recognised in profit or loss on disposal of the foreign operation.

(iv) Cash flow hedge

The effective portion of changes in the fair value of
derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income and accumulated reserves in equity. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss within
other income or other expense.

Amounts accumulated in equity are reclassified in profit or loss in the periods when the hedged
item will affect profit or loss.

When a hedging instrument expires or is sold or terminated, or when a hedge no longer meets
the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast transaction is ultimately recognised in profit or loss. When a forecast transaction is no longer
expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to profit or loss.

(v) AWAC - Embedded Derivatives

Derivatives embedded in other financial instruments or other host contracts are treated as separate derivatives when their risks and characteristics are not closely related to those of host contracts and
the host contracts are not measured at fair value with changes in fair value recognised in profit or loss.

Sale and purchase
contracts may be considered to have financial derivative instruments embedded within them, when future transactions under such contracts are to be executed at prices which will depend on the market prices at the time of specified financial
instruments which themselves are not closely related to the commodities which are the subjects of the contracts. AWAC has in place a number of long term contracts for the purchase of energy which have within their pricing formulae mechanisms to vary
the price depending on the London Metal Exchange (LME) aluminium price at the time, oil prices, Consumer Price Index and are considered to contain embedded derivatives. Future purchases under these contracts are fair valued at each balance date on
the basis of the then-current best indicator of future LME aluminium price, oil prices and Consumer Price Index, over the remaining terms of the contracts. Changes in the fair value from the opening of the period to the balance date are accounted
for as gains or losses, as appropriate, by the relevant AWAC entity. The Group accounts for its share of such transactions within its equity share of net profit/(loss) of associates.

Q DIVIDENDS

Provision is made for the amount of any dividend declared on or before the end of the financial year but not distributed at balance date.

R EARNINGS PER SHARE

(i) Basic earnings per share

Basic earnings per share is calculated by dividing the profit attributable to equity holders of the Company, excluding any costs of servicing equity other than ordinary shares, by the weighted average
number of ordinary shares outstanding during the financial year, adjusted for rights issues, bonus elements in ordinary shares issued during the year and treasury shares issued.

(ii) Diluted earnings per share

Diluted earnings per share adjusts the figures used in the determination of basic earnings per share to take into account the after income tax effect of interest and other financing costs associated with
dilutive potential ordinary shares and the weighted average number of additional ordinary shares that would have been outstanding assuming the conversion of all dilutive potential ordinary shares.

S SEGMENT REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker has been identified as the Chief
Executive Officer.

T PROVISIONS

Provisions for legal claims and service warranties are recognised when the Group has a present legal or constructive obligation as a result of past events, it is more likely than not that an outflow of
resources will be required to settle the obligation, and the amount has been reliably estimated. Provisions are not recognised for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognised
even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

AWAC
is required to rehabilitate bauxite mines, refineries and smelters upon cessation of operations.

Closedown and restoration
costs include the costs of dismantling and demolition of infrastructure or decommissioning, the removal of residual material and the remediation of disturbed areas. Closedown and restoration costs are provided for in the accounting period when the
obligation arising from the related disturbance occurs, whether this occurs during the mine development or during the production phase, based on the net present value of estimated future costs. The cost estimates are calculated annually during the
life of the operation to reflect known developments, and are subject to regular reviews.

Provisions are measured at the
present value of managements best estimate of the expenditure required to settle the present obligation at the end of the reporting period. The discount rate used to determine the present value is a pre-tax rate that reflects current market
assessments of the time value of money and the risks specific to the liability.

The amortisation or unwinding of the discount
applied in establishing the net present value of provisions is charged to profit or loss in each accounting period. Other movements in the provisions for closedown and restoration costs, including those resulting from new disturbance, updated cost
estimates, changes to lives of operations and revisions to discount rates are capitalised within fixed assets. These costs are then depreciated over the lives of the assets to which they relate.

Where rehabilitation is conducted systematically over the life of the operation, rather than at the time of closure, provision is made for
the outstanding continuous rehabilitation work at each balance date. All costs of continuous rehabilitation work are charged to the provision as incurred.

U CONTRIBUTED EQUITY

Ordinary shares are classified as equity.

Incremental costs directly attributable to the issue of new shares or performance rights are shown in equity as a deduction,
net of tax, from the proceeds. Incremental costs directly attributable to the issue of new shares or performance rights, or for the acquisition of a business, are not included in the cost of the acquisition as part of the purchase consideration.

V NEW ACCOUNTING STANDARDS

Certain new accounting standards, interpretations and amendments to existing standards have been published that are mandatory for the
Groups accounting periods beginning 1 January 2014 or later periods. Those which are relevant to the Groups operations are set out below:

IFRS 9 Financial Instruments

This standard addresses the classification,
measurement and derecognition of financial assets and financial liabilities. The mandatory effective date has been left open pending the finalisation of the standard by the IASB however the standard is available for early adoption.

There will be no impact on Groups accounting for financial liabilities, as the new requirements only affect the accounting for
financial liabilities that are designated at fair value through profit or loss and the Group does not have any such liabilities. The derecognition rules have been transferred from IAS 39 Financial Instruments: Recognition and Measurementand
have not been changed. The Group has not yet decided when to adopt IFRS 9.

Amendments to IAS 36 Impairment of assets

These amendments address the disclosure of information about the recoverable amount of impaired assets if that amount is based
on fair value less costs of disposal. The Group intends to apply the amendment from 1 January 2014.

W ROUNDING OF
AMOUNTS

Amounts in the financial statements have been rounded off to the nearest hundred thousand dollars, or as
otherwise indicated.

2. FINANCIAL RISK MANAGEMENT

The Group has exposure to the following risks from their use of financial instruments:



| |  |  | Market risk
| | - |  | -----------



| |  |  | Credit risk
| | - |  | -----------



| |  |  | Liquidity risk
| | - |  | --------------



| |  |  | Fair value measurement.
| | - |  | -----------------------

This note presents information about the Groups exposure to each of the above risks, objectives, policies and processes for measuring and managing risk. Further quantitative disclosures are included
throughout this financial report.

Financial risk management is carried out by a Treasury Committee which is responsible for
developing and monitoring risk management policies.

Risk management policies are established to identify and analyse the risks
faced by the Group to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Groups activities.

(a) MARKET RISK

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and equity prices will affect the Groups income or the value of its investments and borrowings.
The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimising the return.

The Group enters into derivatives, and also incurs financial liabilities, in order to manage market risks. All such transactions are carried out within the guidelines of the Treasury Policies.

(i) Foreign exchange risk

Foreign exchange risk for the Group arises when future commercial transactions and recognised assets and liabilities are denominated in a currency that is not the Groups functional currency.

During 2009 the Group completed a drawdown of funding from the Brazil National Development Bank (BNDES). The funding was
predominately in US dollars with the balance in Brazilian Reais (BRL). To hedge the exposure to the BRL/USD exchange rate and BRL interest rates the Group entered into Cross Currency Interest Rate Swaps (CCIRS) for the full amount of the BRL tranche
to swap the exposure back to US dollars.

Except as described above, the Group generally does not hedge its foreign currency
exposures except through the near-term purchase of currency to meet operating requirements. The change to USD functional currency in January 2010 removed the foreign exchange risk on US dollar borrowings and US dollar denominated assets.

(ii) Price risk

The Group is exposed to commodity price risk through its investment in AWAC.

AWAC
is exposed to the price of various other commodities used in the refining and smelting processes, particularly energy (oil, gas, coal and electricity) and caustic soda. AWAC manages commodity price risks through long-term purchase contracts for some
input costs.

2. FINANCIAL RISK MANAGEMENT (continued)



(iii) Cash flow and fair value interest rate risk

The Groups main interest rate risk arises from its borrowings.

Borrowings by the Group at variable rates expose it to cash flow interest rate risk. Borrowings at fixed rates would expose the Group to
fair value interest rate risk.

When managing interest rate risk, the Group seeks to reduce the overall cost of funds. Group
policy is to generally borrow at floating rates subject to availability of attractive fixed rate deals. During 2013, 2012, the Groups borrowings were all on a variable rate basis.

As part of the BNDES financing, CCIRS for the whole amount of the BRL denominated tranche were used to manage the exposure to BRL interest
rates over the life of the loan.

The consolidated entitys exposure to interest rate risk and the effective weighted
interest rate after the effect of derivative instruments is set out below:

Had interest rates on floating rate debt during 2013 been one percentage point higher/lower than the
average of 4.19 per cent, with all other variable held constant, pre-tax profit for the year would have been $2.5 million lower/higher (2012: $6.3 million lower/higher).

(b) CREDIT RISK

Credit risk arises from cash and cash equivalents,
derivative financial instruments and deposits with banks and financial institutions, as well as credit exposures to customers, including outstanding receivables and committed transactions. For banks and financial institutions, only independently
rated parties with a minimum rating of A- are accepted, and exposure limits are assigned based on actual independent rating and Board approved guidelines.

Credit risk further arises in relation to cross guarantees given to wholly owned subsidiaries (see Note 21 for details). Such guarantees are only provided in exceptional circumstances and are subject to
Board approval.

The carrying amount of financial assets recorded in the financial statements, net of any allowances for
losses, represents the Groups maximum exposure to credit risk without taking account of the value of any collateral obtained.

The Group through its investment in AWAC also has a significant concentration of credit risk to companies controlled by Alcoa Inc. This concentration is accepted as a consequence of the Groups
participation in AWAC.

2. FINANCIAL RISK MANAGEMENT (continued)



(c) LIQUIDITY RISK

Prudent liquidity risk management requires maintaining sufficient cash and credit facilities to ensure the Groups commitments and
plans can be met. This is managed by maintaining committed undrawn credit facilities to cover reasonably expected forward cash requirements.

The table below details the Groups remaining contractual maturity for its non-derivative financial liabilities. The amounts disclosed in the table are the carrying amount of financial liabilities.
In addition, the Group pays interest on these facilities. Interest, after derivative financial instruments, is based on US dollar floating rates for all facilities. The weighted average interest rate on these facilities at balance date is 4.19%
(2012: 3.18%).

Additional information on the Groups borrowings, including committed undrawn facilities, are shown in
Note 15.

(d) FAIR VALUE ESTIMATION

The fair value of financial assets and financial liabilities must be estimated for recognition and measurement or for disclosure purposes.

The carrying value less impairment provision for current receivables and payables is a reasonable approximation of their fair
values due to the short-term nature of the receivables. The fair value of financial liabilities for disclosure purposes is estimated by discounting the future contractual cash flows at the current market interest rate that is available to the Group
for similar financial instruments.

The fair value of derivative instruments are calculated based on discounted cash flow
analysis using the applicable yield curve for the duration of the instruments for non-optional derivatives, and option pricing models for option derivatives.

IFRS 7 Financial Instruments: Disclosure requires disclosure of fair value measurements by level of the following fair value measurement hierarchy:

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities

Level 2 - inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (as
prices) or indirectly (derived from prices)

Level 3 - inputs for the asset or liability that are based on unobservable market
data (unobservable inputs).

The following table below presents the Groups financial assets and financial liabilities
measured and recognised at fair value at 31 December 2013 and 31 December 2012 grouped into Levels 1 to 3 based on the degree to which the fair value is observable:

FOR THE YEARS ENDED 31 DECEMBER 2013, 2012 AND 2011



3. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of
future events that may have a financial impact on the Group and that are believed to be reasonable under the circumstances. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and judgements
that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

AWAC

The Group, through its investment in AWAC, makes estimates and
assumptions concerning the future. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities of AWAC entities and therefore Groups investment in associates
within the next financial year are discussed below.

Embedded derivatives

The Group through its equity investment in AWAC has accounted for derivative financial instruments in accordance with IAS 39 Financial
Instruments: Recognition and Measurement. Estimates for long term commodity prices are used in the determination of the fair value of this liability. Where the actual prices were to differ by 20 per cent to the estimates, it would have the
following effect:



| |  |  | An unfavourable movement would increase the embedded derivatives net liability by $28.8 million (2012: $136.9 million) and decrease the deferred
tax liability by $8.6 million (2012: $41.1 million) and decrease Groups investment in associates by $8.1 million (2012: $38.3 million)
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A favourable movement would decrease the embedded derivatives net liability by $31.0 million (2012: $49.2 million) and increase the deferred tax
liability by $9.3 million (2012: $14.8 million) and increase Groups investment in associates by $8.7 million (2012: $13.8 million).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Electricity hedge

The Group through its equity investment in AWAC
has accounted for derivative financial instruments in accordance with IAS 39 Financial Instruments: Recognition and Measurement. In the determination of the fair value of this asset, estimates surrounding long term electricity prices are
used. Where the actual prices were to differ by 10 per cent to the estimates, it would have the following effect:



| |  |  | An unfavourable movement would decrease the derivative financial instruments asset by $213.6 million (2012: $249.1 million) and decrease the deferred
tax liability by $64.1 million (2012: $74.8 million) and decrease Groups investment in associates by $59.8 million (2012: $69.7 million)
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A favourable movement would increase the derivative financial instruments asset by $213.6 million (2012: $249.1 million) and increase the deferred
tax liability by $64.1 million (2012: $74.8 million) and increase Groups investment in associates by $59.8 million (2012: $69.7 million).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Retirement benefit obligations

The Group recognised a net liability
for retirement benefit obligations under the defined benefit superannuation arrangements, through its investment in AWAC. All plans are valued in accordance with IAS 19 Employee Benefits. These valuations require actuarial assumptions to be
made. All re-measurements (adjusted for IFRS) are recognised in other comprehensive income. Refer Note 1(a) for the details of changes in accounting policy.

Asset retirement obligations

The estimated costs of rehabilitating
mined areas and restoring operating sites are reviewed annually and fully provided at the present value. The amount of obligations recognised under Accounting Principles Generally Accepted in the United States of America (US GAAP) by AWAC is
adjusted to be in compliance with IFRS, and includes the costs of mine areas and residue areas rehabilitation and reclamation, plant closure and subsequent monitoring of the environment. Where rehabilitation and remediation is anticipated to occur
within the next 12 months the provision is carried as a current liability. Any outflow greater than 12 months is held as a non-current liability. This requires judgemental assumptions regarding future environmental legislation, the extent of
reclamation activities required, plant and site closure and discount rates to determine the present value of these cash flows.

For mine reclamation and residue areas the asset retirement obligations are based on detailed studies of useful lives. The provisions have
been estimated using existing technology, at current prices inflated by estimated future CPI and discounted at a rate appropriate for the asset location. The Group accounts for asset retirement obligations via the equity accounted method.

Deferred tax assets

The Group through its equity accounted investment in AWAC has recognised deferred tax assets and liabilities in accordance with IAS12 Income Taxes. Deferred tax assets are measured using tax rates
(and laws) that have been enacted or substantially enacted by the reporting date and are expected to apply when the related deferred asset is realised or the liability is settled. AWACs subsidiary in Brazil applied for a tax holiday related to
its expanded mining and refining operations. If approved, the tax rate for this subsidiary will decrease significantly resulting in future tax savings over the 10-year holiday period. The net deferred tax assets of the subsidiary are required to be
remeasured at the lower holiday rate for the tax losses that will be utilised during the tax holiday period. This requires judgmental assumptions regarding the timing of future taxable profits during the tax holiday period.

3. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS (continued)



Alumina Group

Estimated impairment of investment in associates

The Group tests annually whether the investment in associates has suffered any impairment, in accordance with the accounting policy stated in note 1(h). The recoverable amounts of cashgenerating
units have been determined based on value-in-use calculations. The key assumptions used in the calculation were those relating to future aluminium prices, future alumina prices, oil, electricity, gas prices and exchange rates. Key assumptions are
determined with reference to industry participants and brokers forecasts, commodity and currency forward curves, industry consultant views and brokers consensus.

Management considered the following sensitivities for major assumptions used in the impairment assessment:



| |  |  | Commodities (including aluminium, alumina, caustic, coal, oil and gas) price fluctuation plus or minus 10%
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | Currency rate fluctuation plus or minus 10%
| | - |  | -------------------------------------------



| |  |  | Discount rate increase by 2%.

Allocation of Alba settlement terms and related transactions

As previously disclosed, in September 2012, Alcoa Inc and Alumina Limited had entered into an agreement that the cash costs (including
legal fees) of settlement of the Department of Justice (DoJ) and Securities & Exchange Commission (SEC) investigations, as well as the $85 million civil settlement with Alba reached in October 2012 recorded in the accounts of Alcoa World
Alumina LLC (AWA), will be adjusted to ensure that 85% will be allocated to Alcoa Inc and 15% to Alumina Limited (should settlements be reached on the regulatory investigations, as described above). AWA is a company within the Alcoa World
Alumina and Chemicals (AWAC).

The agreement between Alcoa Inc and Alumina Limited also provides that Alumina Limited will not
provide any funding to AWA for its share of the payments.

With the DoJ and SEC settlements having been reached (refer
Note 12 for further details), the allocation provisions of the above agreement became applicable. After equity accounting for $153.6 million (40%) of 2013 Alba related charges, Alumina Limited further recognised $137.1 million (representing 25%
of the total Alba settlement payments and costs of $548.5 million) as other assets with the corresponding credit recognised in the profit or loss as other income, thus reflecting the allocation agreements provisions.

Alumina Limited is evaluating with Alcoa Inc the structural options (including the form and timing) for the recovery of the other assets,
recognised under the provisions of the allocation agreement. Alumina Limited expects approximately $20 million of the assets to be recovered during 2014 and has classified this amount as current assets.

(e) Accounting policies

The audited combined financial statements of the entities forming AWAC are prepared in accordance with Accounting Principles Generally
Accepted in the United States of America (US GAAP). Adjustments are made to convert the accounting policies under US GAAP to IFRS. The principal adjustments are to the valuation of inventories from last-in-first-out basis to a basis equivalent
to weighted average cost, create an additional asset retirement obligation for dismantling, removal and restoration of certain refineries, valuation of certain long term energy purchase contracts which include an aluminium price component in the
energy price and differences in the recognition of actuarial gains and losses on certain defined benefit plans and the reversal of certain tax credits and fixed asset uplifts included in Alcoa World Alumina Brasil Ltda.

St Croix proceedings

As previously reported, in September 1998, Hurricane Georges struck the U.S. Virgin Islands, including the St. Croix Alumina, L.L.C. (SCA) facility on the island of St. Croix. The wind and rain associated
with the hurricane caused material at the location to be blown into neighbouring residential areas. SCA undertook or arranged various clean-up and remediation efforts. The Division of Environmental Protection (DEP) of the Department of Planning and
Natural Resources (DPNR) of the Virgin Islands Government issued a Notice of Violation that Alcoa has contested. In February 1999, certain residents of St. Croix commenced a civil suit in the Territorial Court of the Virgin Islands seeking
compensatory and punitive damages and injunctive relief for alleged personal injuries and property damages associated with bauxite or red dust from the SCA facility. In September 2009, the Court granted defendants motion for
summary judgment on the class plaintiffs claim for injunctive relief. In October 2009, plaintiffs appealed the Courts summary judgment order dismissing the claim for injunctive relief and in March 2011, the U.S. Court of Appeals for the
Third Circuit dismissed plaintiffs appeal of that order. In September 2011, the parties reached an oral agreement to settle the remaining claims in the case which would resolve the personal property damage claims of the 12 remaining individual
plaintiffs. On 12 March 2012, final judgment was entered in the District Court for the District of the Virgin Islands. AWACs share of the settlement is fully insured. On 23 March 2012, plaintiffs filed a notice of appeal of numerous
non-settled matters, including but not limited to discovery orders, Daubert rulings, summary judgment rulings, as more clearly set out in the settlement agreement/release between the parties. Plaintiffs appellate brief was filed in the Third
Circuit Court on 4 January 2013, together with a motion seeking leave to file a brief of excess length. The court has suspended the remainder of the briefing schedule, including the date for AWACs reply brief, until it rules on
plaintiffs motion to file its brief of excess length. The Third Circuit Court of Appeals issued a new scheduling order regarding briefing in the matter. The matter has been fully briefed with plaintiffs brief filed on 25 November
2013 and the matter is now before the court.

As previously reported, on 14 January 2010, Alcoa was served with a
complaint involving approximately 2,900 individual persons claimed 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 property 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. The complaint names as defendants the same entities as were sued in the February 1999 action earlier
described and have added as a defendant the current owner of the alumina facility property. In February 2010, Alcoa and SCA removed the case to the federal court for the District of the Virgin Islands. Subsequently, plaintiffs filed motions to
remand the case to territorial court as well as a third amended complaint, and defendants have moved to dismiss the case for failure to state a claim upon which relief can be granted. On 17 March 2011, the court granted plaintiffs motion
to remand to territorial court. Thereafter, Alcoa filed a motion for allowance of appeal. The motion was denied on 18 May 2011. The parties await assignment of the case to a trial judge.

As previously reported, on 1 March 2012, Alcoa was served with a complaint involving approximately 200 individual persons claimed 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 property since the time of the hurricane in September 1998. This complaint, Abraham, et al. v.
Alcoa, et al. alleges claims essentially identical to those set forth in the Abednego v. Alcoa complaint. The matter was originally filed in the Superior Court of the Virgin Islands, St. Croix Division, on 30 March 2011. By motion filed
12 March, 2012, Alcoa sought dismissal of this complaint on several grounds, including failure to timely serve the complaint and being barred by the statute of limitations. That motion is still pending.

Legal Matters of Associate relating to Alba Civil Settlement and Government Investigations

Alba Proceeding

The Alba Proceeding was settled in relation to Alcoa Inc and Alcoa World Alumina LLC (AWA) in October 2012, without any admission of liability, by a cash settlement payment of US$85 million, to
be paid by AWA in two equal instalments by the first anniversary of the settlement. Based on the settlement agreement with Alba, AWA recorded a charge of $85 million in 2012 in respect of the Alba Proceeding. In addition, AWA entered into a
long term alumina supply agreement with Alba.

Resolution of U.S. Government Investigations relating to Alba Proceeding

On 9 January 2014, Alcoa Inc announced the resolution of the investigations by the US Department of Justice (DoJ)
and the US Securities and Exchange Commission (SEC) regarding certain legacy alumina contracts with Aluminium Bahrain BSC.

The settlement with the DoJ was reached with Alcoa World Alumina LLC (AWA). AWA is a Company within Alcoa World Alumina and Chemicals
(AWAC). As part of the DoJ resolution, AWA will pay a total of $223 million, including a fine of $209 million payable in five equal instalments over four years. The first instalment of $41.8 million, plus a one-time administrative forfeiture of
$14 million, were paid in the first quarter of 2014, and the remaining instalments of $41.8 million each will be paid in the first quarters of 2015-2018.

Alcoa Inc 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 Foreign Corruption Practices Act.
Under the terms of the settlement with the SEC, Alcoa Inc agreed to a settlement amount of $175 million, but will be given credit for the $14 million one-time forfeiture payment, which is part of the DoJ resolution, resulting in a total cash payment
to the SEC of $161 million payable in five equal instalments over four years. The first instalment of $32.2 million was paid to the SEC in the first quarter of 2014, and the remaining instalments of $32.2 million each will be paid in the first
quarters of 2015-2018.

Other claims

There are potential obligations that may result in a future obligation due to the various lawsuits and claims and proceedings which have
been, or may be, instituted or asserted against entities within AWAC, including those pertaining to environmental, product liability, and safety and health matters. While the amounts claimed may be substantial, the ultimate liability cannot now be
determined because of the considerable uncertainties that existed at balance date. Also, not every plaintiff has specified the amount of damages sought in their complaint. Therefore, it is possible that results of operations or liquidity in a
particular period could be materially affected by certain contingencies.

Pursuant to the terms of the AWAC Formation
Agreement, Alcoa Inc and Alumina Limited have agreed to remain liable for Extraordinary Liabilities (as defined in the agreement) as well as for certain other pre-formation liabilities, such as existing environmental conditions, to the extent of
their pre-formation ownership of the AWACs entity or asset with which the liability is associated.

In December 2013, Alumina Limited established a new US$300 million syndicated bank facility with tranches
of two and four years and cancelled several bilateral and syndicated bank facilities, which were surplus to requirements. The new syndicated facility was fully committed as at 31 December 2013 and became available to draw funds on
30 January 2014 following satisfaction of all conditions precedent.

Available funding facilities at 31 December 2013
were a bilateral bank facility and a development bank loan. The bilateral facility is available in US dollars. The development bank loan is fully drawn in US dollars and BRL and amortises at approximately $51 million per annum. Funding facilities in
currencies other than US dollars have been converted to US dollar equivalents at period end exchange rates. Excluding the development bank loan amortisation, there is no debt maturing in 2014.

Current liabilities include $50.6 million of repayments on the facility from the BNDES that are due before 31 December 2014.
Current liabilities of $61.4 million exceed current assets of $47.8 million. However, the Directors have concluded that the liabilities will be met using available cash and undrawn committed facilities whose maturities extend beyond
31 December 2014.

(a) Ordinary shares

Ordinary shares, which have no par value, entitle the holder to participate in dividends and the proceeds on winding up of the Company in
proportion to the number of, and amounts paid on, the shares held.

On 14 February 2013, CITIC Resources Australia Pty Ltd
and Bestbuy Overseas Co., Ltd unconditionally subscribed, in aggregate, for 366,029,428 fully paid ordinary shares in Alumina Limited, being 15% of Alumina Limiteds then current capital base, representing 13.04% of Alumina Limiteds
capital base following completion (the Placement).

The Placement raised approximately A$452 million based on an
issue price of A$1.235 per share, which reflected a premium of approximately 3% to the closing price of Alumina Limited shares on 13 February 2013 and a premium of 11% to the volume weighted average price of Alumina limited shares for the 30
day period ending 13 February 2013.

(b) Capital risk management

The Groups objectives when managing capital is to safeguard the ability to continue as a going concern, so that it can continue to
provide returns for shareholders and to maintain an optimal capital structure to reduce the cost of capital.

The Boards
policy is to maintain a strong capital base so as to maintain investor, creditor and market confidence and to sustain future development of the business. In order to maintain or adjust the capital structure, the Group may adjust the amount of
dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

The Group
calculates the gearing ratio as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as equity as shown in the balance sheet plus debt.

The gearing ratios at 31 December 2013 and 31 December 2012 were as follows:



|                                |  |       |    |  |             |  |         |      |  |  |         |

The decrease in the gearing ratio during 2013 resulted primarily from the share placement with the funds
primarily used to repay debt.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)

FOR THE YEARS ENDED 31 DECEMBER 2013, 2012 AND 2011



18. SHARE-BASED PAYMENTS

(a) Alumina Employee Share Plan (ESP)

This is a plan under which employees may be invited to participate in the grant of a conditional entitlement to fully paid ordinary shares (a Performance Right). The Boards intention is to make
offers to each employee, but this is subject to annual determination by the Board in respect of each individual for each grant. The CEO of the Company may recommend variation in participation.

A person is only eligible to participate in the Plan and to be granted performance rights under the Plan if they are an employee, and have
satisfied the criteria that the Board decides for participation in the Plan.

For performance rights granted prior to 2014, if
less than 100% vest when tested initially at the end of a three year period, two further tests apply (over a four week period) six and 12 months after the initial test. Any performance rights which do not vest after the second retest will lapse.

An invitation is not transferable. An employee may only apply for performance rights in his or her name and not in the name
of, or on behalf of, another person or entity. On vesting, each performance right is an unconditional entitlement to one fully paid ordinary share.

On termination of employment of any individual, their participation in the Plan is finalised and any performance rights not vested lapse unless the directors decide otherwise.

The value per performance right is independently calculated by Mercer Finance and Risk Consulting using the assumptions underlying the
Black-Scholes methodology to produce a Monte Carlo simulation model which allows the incorporation of the hurdles that must be met before the performance rights vest.

Set out below are the assumptions made for the performance rights granted on 8 February 2013:



|                              |  |   |      |  
|----------------------------- |  | - | ---- | -
|Share Price at Valuation date |  | $ | 1.15 |  
|Risk Free rate                |  |   | 2.8  | %
|Dividend Yield                |  |   | 3.0  | %
|Volatility                    |  |   | 41   | %

The volatility assumption is based on the actual volatility of Alumina Limiteds daily closing share
price over the three year period to the valuation date.

Set out below are summaries of performance rights granted under the
Plan:

(c) Nature and purpose of reserves

(i) Asset revaluation reserve

The balance standing to the credit of the reserve may be used to satisfy the distribution of bonus shares and is only available for the payment of cash dividends in limited circumstances as permitted by
law.

(ii) Capital reserve

The reserve records dividends arising from share of profits on sale of investments.

(iii) Foreign currency translation reserve

The foreign currency translation reserve represents the exchange differences on the translation of non-US dollar functional currency operations within the Group into US dollars.

(iv) Share-based payments reserve

The share-based payments reserve is used to recognise the fair value of performance rights issued but not exercised.

(v) Option premium on convertible bonds

The convertible bond was accounted
for as a compound instrument at the Group level. The option premium represented the equity component (conversion rights) of the convertible bond. The convertible bond was fully redeemed in 2011.

(vi) Cash-flow hedge reserve

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income (refer Note 1(p)(iv)). The year-end
balance and movements within the cash-flow hedge reserve of AWAC is accounted for via the equity accounting method.

28. EVENTS OCCURING AFTER THE BALANCE SHEET DATE

On 9 January 2014, Alcoa Inc announced the resolution of the investigations by the US Department of Justice and the
US Securities and Exchange Commission regarding certain legacy alumina contracts with Aluminium Bahrain BSC. Refer further details in Note 5 and Note 12.

On 6 February 2014, Alumina Limited announced its intention to delist from the NYSE.

On 18 February 2014 Alcoa Inc announced the permanent closure of AWACs Point Henry aluminium smelter. AWAC is 60% owned and managed by Alcoa Inc and 40% owned by Alumina Limited. Total
AWAC restructuring related charges associated with the closure of the Point Henry smelter are expected to be approximately $250 million after tax. AWACs cash costs after tax during 2014 in respect of the closure are expected to total
approximately $50 million. Further after tax cash costs of approximately $70 million are expected to be incurred by AWAC in later years. The announcement also notes that the AWAC Anglesea coal mine and power station, which supplies approximately 40%
of the power needs for the Point Henry smelter, has the potential to operate as a standalone facility after the smelter closes. Alcoa of Australia Limited will actively seek a buyer for the facility.

Report of Independent Registered Public
Accounting Firm

To the Board of Directors and Shareholders of Alumina Limited

In our opinion, the accompanying consolidated balance sheet and the related consolidated statements of profit or loss and other comprehensive income,
changes in equity, and cash flows present fairly, in all material respects, the financial position of Alumina Limited and its subsidiaries at 31 December 2013 and 31 December 2012, and the results of their operations and their cash flows
for each of the three years in the period ended 31 December 2013 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all
material respects, effective internal control over financial reporting as of 31 December 2013, based on criteria established in Internal ControlIntegrated Framework (1992)issued by the Committee of Sponsoring Organisations of the
Treadway Commission (COSO). The Companys management is responsible for these financial statements, for maintaining effective internal control over financial reporting, included in Managements Annual Report on Internal Control Over
Financial Reporting appearing under Item 15(b) in this Form 20-F. 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), and International Standards on Auditing. 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.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with 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.

(US dollars in millions)



A. Summary of Significant Accounting Policies

Principles of Combination and Basis of Presentation

The combined financial statements of Alcoa World Alumina and Chemicals (AWAC) have been prepared pursuant to a Formation
Agreement dated December 21, 1994 between Alcoa Inc. (Alcoa) and WMC Limited of Melbourne, Australia (WMC), as amended. Effective December 11, 2002, WMC shareholders voted to create two entities, WMC Resources
Limited and Alumina Limited, resulting in existing WMC shareholders receiving shares in a new listed entity WMC Resources Limited, which holds non AWAC businesses. AWAC is owned 60% by Alcoa and 40% by Alumina Limited and consists
principally of bauxite, alumina and alumina-based chemicals businesses and investments managed and controlled by Alcoa.

The
combined financial statements are prepared in conformity with accounting principles generally accepted in the United States of America and require management to make certain judgments, estimates, and assumptions. These estimates affect the reported
amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and affect the amounts of revenues and expenses reported during the period. Actual results could differ from those
estimates upon subsequent resolution of identified matters. Certain amounts in previously issued financial statements were reclassified to conform to the 2013 presentation.

The following operating entities represent the combined operations of AWAC and form the basis of the combined financial statements:



|                               |  |

|AWA Saudi Limited**            |  | Saudi Arabia 
|Enterprise Partnership         |  | Australia    



|* | Alcoa World Alumina LLC holds AWACs mining and refining interests in the United States, Suriname, Jamaica and Guinea (collectively referred to as the
Combined LLCs).
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|** | AWA Saudi Limited holds AWACs investment in a mining and refining operating joint venture in the Kingdom of Saudi Arabia owned 25.1% by AWAC and 74.9% by Saudi
Arabian Mining Company (Maaden).
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The combined financial statements have been carved out from
the books and records of Alcoa. All transactions between entities included in the combined financial statements have been eliminated. The statements of (loss) income include all items of revenue and income generated by AWAC and all items of expense
directly incurred by AWAC. These include expenses charged to AWAC by Alcoa in the normal course of business. The amounts have been allocated on a basis considered reasonable by management using either specific identification or proportional
allocations based on usage, headcount or other reasonable methods of allocation. As a result of these allocated amounts, the financial statements of AWAC may not be indicative of the results that would be presented if AWAC had operated as an
independent stand-alone entity. The combined financial statements reflect amounts necessary in order to depict the combined financial position, results of operations and cash flows of AWAC on a stand-alone basis. For additional information
concerning expenses charged to AWAC by Alcoa see Note I.

Related Party Transactions

AWAC sells alumina and aluminum to Alcoa. These transactions are intended to represent amounts negotiated at arms-length terms.
Additionally, Alcoa provides employee, administrative and other services to AWAC. These amounts have been recorded on a reasonable basis representative of cost. AWAC has amounts due to and from related parties as a result of these transactions. For
additional information on related party transactions see Note I.

Cash and 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 U.S. inventories determined under the last-in, first-out (LIFO) method. The cost of other inventories is principally
determined under the average-cost method. See Note D for additional information.

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 (numbers in years):



|                  |  |            |    |  |           |  |    | 
|----------------- |  | ---------- | -- |  | --------- |  | -- | 
|                  |  |            |    |  | Machinery | 
|                  |  |            |    |  | and       | 
|                  |  | Structures |    |  | Equipment | 
|                  |  |           
|Alumina refining  |  |            | 30 |  |           |  | 26 | 
|Bauxite mining    |  |            | 31 |  |           |  | 17 | 
|Aluminum smelting |  |            | 35 |  |           |  | 21 | 

Gains or losses from the sale of assets are generally recorded in other income. Repairs and maintenance
are charged to expense as incurred. Interest related to construction of qualifying assets is capitalized as part of construction costs. See Note E for additional information.

Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying
amounts 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 to which the assets (asset group) related 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) analysis. The determination of what constitutes an asset group, the associated estimated
undiscounted cash flows, and the estimated useful lives of assets also require significant judgments.

Goodwill

Goodwill is not amortized; instead, it is tested for impairment annually (as of October 31) or more frequently if indicators of
impairment exist or if a decision is made to sell 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 values 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. AWAC has two reporting units:
Alumina and Primary Metals.

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 (more 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, 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.

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.

Under the two-step quantitative impairment test, the evaluation of impairment involves
comparing the current fair value of a reporting unit to its carrying value, including goodwill. AWAC 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, costs to
produce, 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 members equity.

In developing the fair value of these reporting units, AWAC estimates future
cash flows using London Metal Exchange (LME) forward curve pricing and operating cost assumptions management believes are reasonable based on expected and historical performance. The following could have a negative impact on the estimated fair
values of Alumina and Primary Metals: a significant, protracted decrease in LME and alumina prices; decrease in long-term profitability; decrease in the long-term demand for aluminum; substantial reductions in AWACs end markets and volume
assumptions; and an increase in discount rates.

During the 2013 annual review of goodwill, management proceeded directly to
the two-step quantitative impairment test for both the Alumina and Primary Metals reporting units. The estimated fair value of Alumina exceeded its fair value, resulting in no impairment.

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, AWAC recorded a goodwill impairment of $30.2, which is recorded in Restructuring and other charges in the Combined Statements of (Loss) Income. As a result of the goodwill impairment, there is no goodwill remaining for the Primary Metals
reporting unit.

The impairment of Primary Metals goodwill results 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

Computer software costs consist primarily of software costs associated with an enterprise business solution (EBS). Capitalized EBS costs are amortized over ten years.

Accounts Payable Arrangements

AWAC participates in computerized payable settlement arrangements with certain vendors and third-party intermediaries. The 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. AWAC makes payment to the third-party intermediary on the date stipulated in accordance with the commercial
terms negotiated with its vendors. The amounts outstanding under these arrangements that will be paid to the third-party

intermediaries have been classified as short-term borrowings in the combined balance sheet and as cash provided from financing activities in the combined statement of cash flows. See Note H
for additional information.

Equity Investments

AWAC 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 AWAC 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 as determined through use of a DCF model. An impairment that is other than temporary could significantly and adversely impact reported results of operations and members equity.

Revenue Recognition

AWAC 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 customers and depend on the product, the country of origin, and the type of transportation (truck, train, or vessel).

Deferred Alumina Sales Revenue

AWAC 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. As a result, prepayment of $240.0 related to an agreement with a third party customer received in 1997, is being amortized over the life of the contract based
on the tonnage shipped. The amount of the prepayment still deferred at December 31, 2013 and 2012 was $108.8 and $116.0, respectively. The amount of revenue recognized related to this agreement was $7.2, $8.0 and $9.0, for the years ended
December 31, 2013, 2012 and 2011, respectively.

Environmental Matters

Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by
past operations, and which do not contribute to future revenues, are expensed. Liabilities are recorded when remedial efforts are probable and the costs 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 AWAC has reason to believe such parties will not fully pay their proportional 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. See Note P for additional information.

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 only 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. See Note O for additional information.

Asset Retirement Obligations

AWAC recognizes asset retirement obligations (AROs) related to legal obligations associated with the normal operation of AWAC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. AWAC also recognizes AROs for any significant lease restoration obligation, if
required by a lease agreement. 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, AWAC capitalizes asset retirement costs by
increasing the carrying amount of the related long-lived assets and depreciating these assets over the remaining useful life. See Note C for additional information.

Certain conditional asset retirement obligations (CAROs) related to alumina refineries and aluminum smelters have not been recorded in the combined 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 AWACs control.
Such uncertainties exist as a result of the perpetual nature of refineries and smelters, maintenance and upgrade programs, and other factors preventing a reasonable estimation surrounding the ultimate settlement date. At the date a reasonable
estimate of the ultimate settlement date can be made, AWAC would record a retirement obligation 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. If AWAC was required to shutdown all such facilities immediately, the estimated
CARO as of December 31, 2013 ranges from $3.4 to $26.7 per facility (10 structures) in todays dollars.

Mineral Rights

AWAC recognizes mineral rights upon specific acquisitions of land that include such underlying rights, primarily in Jamaica. 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 Combined Balance Sheet.

Deferred Mining Costs

AWAC 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 AWAC 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 Combined Balance Sheet.

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 AWAC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 the Company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.

AWAC consists of a variety of different tax-paying legal entities. Income taxes are accrued and recorded on the financial statements of
entities within AWAC except for entities that are multiple member limited liability companies (LLCs). LLC income is taxable to the members that hold the LLC interest (for U.S. federal and most state income tax purposes). Therefore,
current and deferred U.S. and most state tax assets and liabilities of the LLCs are recorded in the financial statements of the members and, thus, are not reflected in AWACs combined financial statements. See Note L for additional
information.

Stock-Based Compensation

Certain employees of AWAC receive stock-based awards under Alcoas stock incentive plans, and AWAC records an expense for these
plans. AWAC recognizes compensation expense for employee equity grants using the nonsubstantive 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. 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, annual forfeiture rate and exercise behavior. These
assumptions may differ significantly between grant dates because of changes in the actual results of these inputs over time.

Most plan participants can choose whether to receive their award in the form of stock options, restricted share units, 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 cash flow hedges, AWAC 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 these hedges are recorded in 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 are recorded in other income or expense.

AWAC 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 combined balance sheet. The effective portions of the changes in the fair values of these
derivatives are recorded in other comprehensive (loss) income and are reclassified to sales 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 combined statement of cash flows in a manner consistent with the underlying transactions. See Note M for additional information.

Foreign Currency

The local currency is the functional currency for
AWACs significant operations outside the U.S., except in Jamaica and Suriname, which use the U.S. dollar. The determination of the functional currency in these countries is made based on the appropriate economic and management indicators.

Other (Income) Expense, Net

Transactions which result in a gain or loss that are not part of ongoing operations are classified in other (income) expense, net in the Combined Statement of (Loss) Income. See Note R for additional
information.

Recently Adopted Accounting Guidance

Comprehensive Income

On January 1, 2013, AWAC adopted changes issued by the Financial Accounting Standards Board (FASB) to the reporting of amounts reclassified out of accumulated other comprehensive income. These
changes require an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety
to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts.
These requirements are to be applied to each component of accumulated other comprehensive income. Other than the additional disclosure requirements, the adoption of these changes had no impact on the combined financial statements.

The following table details the activity of the three components that comprise Accumulated other comprehensive (loss) income for AWAC:

On January 1, 2012, AWAC adopted changes issued by the Financial Accounting Standards Board (FASB) to conform existing guidance
regarding fair value measurement and disclosure between GAAP and International Financial Reporting Standards. These changes both clarify the FASBs intent about the application of existing fair value measurement and disclosure requirements and
amend certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The clarifying changes relate to the application of the highest and best use and valuation premise concepts, measuring the
fair value of an instrument classified in a reporting entitys shareholders equity, and disclosure of quantitative information about unobservable inputs used for Level 3 fair value measurements. The amendments relate to measuring the
fair value of financial instruments that are managed within a portfolio; application of premiums and discounts in a fair value measurement; and additional disclosures concerning the valuation processes used and sensitivity of the fair value
measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entitys use of a nonfinancial asset in a way that differs from the assets highest and best use, and the categorization by level in the
fair value hierarchy for items required to be measured at fair value for disclosure purposes only. Other than the additional disclosure requirements (Note M), the adoption of these changes had no impact on the combined financial statements.

On January 1, 2011, AWAC adopted changes issued by the FASB to disclosure requirements for fair value measurements.
Specifically, the changes require a reporting entity to disclose, in the reconciliation of fair value measurements using significant unobservable inputs (Level 3), separate information about purchases, sales, issuances, and settlements (that
is, on a gross basis rather than as one net number). These changes were applied to the disclosures in Note K and Note M to the combined financial statements.

Goodwill

On January 1, 2011, AWAC adopted changes issued by the FASB
to the testing of goodwill for impairment. These changes require an entity to perform all steps in the test for a reporting unit whose carrying value is zero or negative if it is more likely than not (more than 50%) that a goodwill impairment exists
based on qualitative factors. This will result in the elimination of an entitys ability to assert that such a reporting units goodwill is not impaired and additional testing is not necessary despite the existence of qualitative factors
that indicate otherwise. Based on the then most recent impairment review of AWAC goodwill (2011 fourth quarter), the adoption of these changes had no impact on the combined financial statements.

In September 2011, the FASB issued changes to the testing of goodwill for impairment. These changes provide an entity 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 (more than 50%) that the fair value of a reporting unit is less than its carrying amount. Such
qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and other relevant entity-specific events. 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, otherwise no further analysis is required. An entity also may elect not to perform the
qualitative assessment and, instead, go directly to the two-step quantitative impairment test. Under either option) the ultimate outcome of the goodwill impairment test should be the same. These changes are required to become effective, for AWAC for
any goodwill impairment test performed on January 1, 2012 or later; however, early adoption is permitted. AWAC elected to early adopt these changes in conjunction with managements annual review of goodwill as of October 31, 2011 (see
the Goodwill section of Note A above). The adoption of these changes had no impact on the combined financial statements.

Derivative Instruments and Hedging Activities

On January 1, 2013, AWAC adopted changes to the disclosure of offsetting assets and liabilities. These changes require an entity to
disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement.
The enhanced disclosures will enable users of an entitys financial statements to understand and evaluate the effect or potential effect of master netting arrangements on an entitys financial position, including the effect or potential
effect of rights of setoff associated with certain financial instruments and derivative instruments. These changes become effective for AWAC on January 1, 2013. Other than the additional disclosure requirements (see Note M), the adoption
of these changes had no impact on the combined financial statements.

On July 17, 2013, the FASB issued and AWAC adopted
changes related to hedge accounting. These changes permit an entity to use the Fed Funds Effective Swap Rate as a U.S. benchmark interest rate for hedge accounting purposes. Previously only interest rates on direct Treasury obligations of the U.S.
government and the London Interbank Offered Rate swap rate were considered benchmark interest rates. The benchmark interest rate is used to assess the interest rate risk associated with a hedged items fair value or a hedged transactions
cash flows. Also, the changes remove the restriction on using different benchmark rates for similar hedges. These changes are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17,
2013. The adoption of these changes had no impact on the combined financial statements.

Other

On January 1, 2012, AWAC adopted changes issued by the FASB to the presentation of comprehensive income. These changes give an entity
the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements;
the option to present components of other comprehensive income as part of the statement of changes in members equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income
must be reclassified to net income were not changed. Management elected to present the two-statement option. Other than the change in presentation, the adoption of these changes had no impact on the combined financial statements.

On January 1, 2011, AWAC adopted changes issued by the FASB to revenue recognition for multiple-deliverable arrangements. These
changes require separation of consideration received in such arrangements by establishing a selling price hierarchy (not the same as fair value) for determining the selling price of a deliverable, which will be based on available information in the
following order: vendor-specific objective evidence, third-party evidence, or estimated selling price; eliminate the residual method of allocation and require that the consideration be allocated at the inception of the arrangement to all
deliverables using the relative selling price method, which allocates any discount in the arrangement to each deliverable on the basis of each deliverables selling price; require that a vendor determine its best estimate of selling price in a
manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis; and expand the disclosures related to multiple-deliverable revenue arrangements. The adoption of these changes had no impact on the
combined financial statements, as AWAC does not currently have any such arrangements with its customers.

On January 1,
2011, AWAC adopted changes issued by the FASB to the classification of certain employee share-based payment awards. These changes clarify that there is not an indication of a condition that is other than market, performance, or service if an
employee share-based payment awards exercise price is denominated in the currency of a market in which a substantial portion of the entitys equity securities trade and differs from the functional currency of the employer entity or
payroll currency of the employee. An employee share-based payment award is required to be

classified as a liability if the award does not contain a market, performance, or service condition. Prior to this guidance, the difference between the currency denomination of an employee share-based payment awards exercise price and the functional currency of the employer entity or payroll currency of the employee was not a factor considered by management when determining the proper
classification of a share-based payment award. The adoption of these changes had no impact on the combined financial statements.

Recently Issued Accounting Guidance

In February 2013, the FASB
issued changes to the accounting for obligations resulting from joint and several liability arrangements. These changes require an entity to measure such obligations for which the total amount of the obligation is fixed at the reporting date as the
sum of (i) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors, and (ii) any additional amount the reporting entity expects to pay on behalf of its co-obligors. An entity will also be
required to disclose the nature and amount of the obligation as well as other information about those obligations. Examples of obligations subject to these requirements are debt arrangements and settled litigation and judicial rulings. These changes
become effective for AWAC on January 1, 2014. Management has determined that the adoption of these changes will not have an impact on the combined financial statements, as AWAC does not currently have any such arrangements.

In March 2013, the FASB issued changes to a parent entitys accounting for the cumulative translation adjustment upon
derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. A parent entity is required to release any related cumulative foreign currency translation adjustment from accumulated other
comprehensive income into net income in the following circumstances: (i) a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity if the sale or transfer
results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided; (ii) a partial sale of an equity method investment that is a foreign entity; (iii) a partial sale
of an equity method investment that is not a foreign entity whereby the partial sale represents a complete or substantially complete liquidation of the foreign entity that held the equity method investment; and (iv) the sale of an investment in
a foreign entity. These changes become effective for AWAC on January 1, 2014. Management has determined that the adoption of these changes will need to be considered in the combined financial statements in the event Alcoa initiates any of the
transactions described above.

In July 2013, the FASB issued changes to the presentation of an unrecognized tax benefit
when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. These changes require an entity to present an unrecognized tax benefit as a liability in the financial statements if (i) a net operating loss
carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position,
or (ii) the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset to settle any additional income taxes that would result from the disallowance of a tax
position. Otherwise, an unrecognized tax benefit is required to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. Previously,
there was diversity in practice as no explicit guidance existed. These changes become effective for AWAC on January 1, 2014. Management has determined that the adoption of these changes will not have a significant impact on the combined
financial statements.

B. Nature of Operations

AWAC is owned 60% by Alcoa and 40% by Alumina Limited and consists principally of bauxite, alumina and alumina-based chemicals businesses and investments managed and contributed by Alcoa. Primarily all
bauxite mined by AWAC entities is refined into alumina by AWAC through a chemical process. The alumina is then sold to customers to be smelted into primary aluminum. Approximately 47%, 46%, and 42% of AWACs respective 2013, 2012, and 2011
alumina production was sold to Alcoa. In addition, Alcoa of Australia (AofA), a significant entity within AWAC, operates integrated aluminum facilities in Australia including mining, refining and smelting operations. Approximately 76%,
80%, and 80% of AofAs 2013, 2012, and 2011 revenues were derived from alumina, and the balance was derived principally from primary aluminum.

During 2013, capital contributions from members of $31.5 were used to fund the Maaden investment.

During 2012, capital contributions from members of $428.4 were primarily used to fund the Maaden investment and their interest in the Enterprise Partnership. The remaining contributions were used to
fund final construction on the Juruti mine (Brazil), and to support operations in Spain.

During 2011, capital contributions
from members were used to support operations in Spain, totaling $275.8, with the remaining contributions of $150.9 primarily used to fund remaining construction at the Juruti mine.

In 2011, Alcoa Inc. made a $33.0 contribution to AWAC for purposes of investment in the Maaden refining and mining business. Alcoa
Inc. did not issue a cash call requesting a matching contribution from Alumina Limited. During 2013, Alcoa Inc. determined that this contribution would be used for purposes of the Maaden rolling business as opposed to the refining and mining
business. Alumina Limited never contributed a matching amount and the Alcoa Inc. contribution was returned to Alcoa Inc. (and simultaneously invested in the Maaden rolling business) and was accounted for as a return of capital.

C. Asset Retirement Obligations

AWAC 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.

In addition to the above AROs, certain CAROs related to alumina refineries and aluminum smelters have not been recorded in the combined
financial statements due to uncertainties surrounding the ultimate settlement date. Such uncertainties exist as a result of the perpetual nature of the refineries and smelters, maintenance upgrade programs and other factors. At the date a reasonable
estimate of the ultimate settlement date can be made, AWAC would record a retirement obligation 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 AWAC was required to shutdown all such facilities immediately, the estimated CARO as of December 31, 2013
ranges from $3.4 to $26.7 per facility (10 structures) in todays dollars.

The following table details the changes in the
carrying amounts of AROs at December 31:



|                             |  |      |       |   |      |   |       |

|Balance at end of year       |  | $    | 379.0 |   |      | $ | 401.3 |  
|                             |  |      |       |   |      |   |       |  

AROs are recorded in Other current liabilities and Other noncurrent liabilities and deferred credits on
the accompanying Combined Balance Sheet.

D. Inventories



|                        |  |      |       |  |      |   |       |

|                        |  | 2013 |       |  | 2012 |  
|                        |  |     
|Finished goods          |  | $    | 5.8   |  |      | $ | 4.2   | 
|Work-in-process         |  |      | 67.0  |  |      |   | 67.4  | 
|Bauxite and alumina     |  |      | 264.7 |  |      |   | 318.3 | 
|Purchased raw materials |  |      | 201.7 |  |      |   | 262.8 | 
|Operating supplies      |  |      | 132.0 |  |      |   | 155.3 | 
|                        |  |      |       |  |      |   |       | 
|                        |  | $    | 671.2 |  |      | $ | 808.0 | 
|                        |  |      |       |  |      |   |       | 

Approximately 11% and 12% of total inventories at December 31, 2013 and 2012, respectively, were
valued on a LIFO basis. If valued on an average cost basis, total inventories would have been $55.0 and $59.7 higher at the end of 2013 and 2012, respectively.

AWAC
and the Saudi Arabian Mining Company, known as Maaden, have a 30-year 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 bauxite mine and alumina refinery in Saudi Arabia. Specifically, the project to be developed by the joint venture will consist of 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, and an alumina refinery with an initial capacity of 1,800 kmt. The refinery is being constructed in an industrial area at
Ras Al Khair (formerly Ras Az Zawr) on the east coast of Saudi Arabia. First production for the mine and refinery is expected in 2014. The joint venture is owned 74.9% by Maaden and 25.1% by AWAC.

I. Related Party Transactions

Sales to related parties included in the combined statements of (loss) income consist of sales of alumina and alumina-based chemicals to
the majority owner of AWAC, Alcoa. The terms for all transactions and agreements between related parties and AWAC are established by negotiation between the parties.

Entities within AWAC have entered into contractual agreements with Alcoa for employee services, an administrative services agreement, a commodity hedging agreement and an alumina sales agreement. Total
costs incurred by AWAC for these agreements were approximately $90.6 in 2013, $84.2 in 2012, and $75.2 in 2011. AWAC also has a long-term bauxite purchase agreement with an equity investee. Total purchases under this agreement were approximately
$192.8, $193.0 and $162.9 during 2013, 2012 and 2011, respectively.

Certain employees of AWAC receive stock-based awards under
Alcoas stock incentive plans, and AWAC records an expense for these plans. In 2013, 2012 and 2011, AWAC was charged and paid $1.7, $1.4 and $3.5, respectively, for stock option exercises and restricted share unit distributions under Alcoa
stock incentive plans. As options are exercised, amounts to reimburse for issuance of shares were reflected as a dividend paid to partners, net of $0.5 in 2013, $0.4 in 2012 and $1.1 in 2011.

Related Party Notes Receivable

In 2011, three AWAC entities entered into an arrangement with Alcoa Global Treasury Services (AGTS), where the entities excess cash is swept to AGTS periodically in exchange for a note receivable
bearing short-term interest. The participating AWAC entities are Australia, Spain and Suriname. The value of the notes at December 31, 2013 are $91.5, $0.0 and $0.0, respectively. The value of the notes at December 31, 2012 are $77.5,
$11.2 and $0.0, respectively.

J. Lease Expense

Certain equipment, including process control hardware and software, as well as warehousing, office space, and ocean going vessels are under operating lease agreements. Total expense from continuing
operations for all leases was $83.1 in 2013, $95.6 in 2012 and $111.6 in 2011. Under operating leases, minimum annual rentals are $69.8 in 2014, $61.2 in 2015, $52.1 in 2016, $47.7 in 2017, $43.6 for 2018 and a total of $161.2 for 2019 and
thereafter.

K. Pension Plans and Other Postretirement Benefits

Entities within AWAC maintain pension plans covering certain non U.S. employees. Pension benefits generally depend upon 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.

Entities within AWAC maintain health care and life insurance benefit plans covering certain non U.S. retired employees. Generally,
the medical plans pay a percentage of medical expenses, reduced by deductibles and other coverages. Life benefits are generally provided by insurance contracts. The entities retain the right, subject to existing agreements, to change or eliminate
these benefits.

|Rate of compensation increase |  |      | 3.85 | % |      |  | 3.89 | %

For a significant portion of the AWAC benefit obligation, the discount rate is based upon a yield
available on government bonds plus a corporate bond spread with a term suitable to match the liabilities.

For plans in countries that have a deep corporate bond market, the discount rate is
determined using an AWAC-specific yield curve model (above-median) developed with the assistance of an external actuary. The cash flows of these 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, manufacturing, transportation, insurance, and pharmaceutical, among others. The yield curve model parallels
the plans projected cash flows, which have an average duration of ten years, and the underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy AWACs plans obligations multiple times.

The expected return on plan assets is based on historical performance as well as expected future rates of
return on plan assets considering the current investment portfolio mix and the long-term investment strategy.

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 2014, 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.

Assumed health care cost trend rates have an effect on the amounts reported for the health care plan. A one-percentage point change in
assumed health care cost trend rates would have the following effects:

Plan Assets

AWACs pension plans investment policy, weighted average asset allocations at December 31, 2013 and 2012, by asset
category, are as follows:

|                  |  |             |       |   |             |      |     |   |  |  |     |  
|                  |  |             |       |   |             |      | 100 | % |  |  | 100 | %

The basic goal underlying the pension plan investment policy is to ensure that the assets of the plan,
along with expected plan sponsor contributions, will be invested in a prudent manner to meet the obligations of the plan as those obligations come due. Investment practices must comply with applicable laws and regulations.

Each of the AWACs pension plans has its own policy range and their assets at year end are within those ranges. The Australia pension
plan assets approximate 60% of the total assets and therefore, their policy range is disclosed.

Numerous asset classes with
differing expected rates of return, return volatility and correlations are utilized to reduce risk by providing diversification. Debt securities comprise a significant portion of the portfolio due to their plan-liability-matching characteristics and
to address the plans cash flow requirements. Additionally, diversification of investments within each asset class is utilized to further reduce the impact of losses in single investments. 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 trustee 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.

Equity Securities

These securities consist of direct investments in the stock of publicly traded companies and are valued based on the closing price reported in an active market on which the individual securities are
traded. As such, the direct investments are generally classified in Level 1. Also, these securities consist of 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. As such, these securities are generally included in Level 1 if quoted in an active market, otherwise they are included in Level 2.

Debt Securities

These securities consist of publicly traded U.S. and non U.S. fixed interest obligations (principally corporate bonds and debentures).
Such investments are valued through consultation and evaluation with brokers in the institutional market using quoted prices and other observable market data. As such, a portion of these securities are included in both Level 1 and 2.
Additionally these securities consist of 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.
As such, these investments are generally classified as Level 3.

Other Investments

These investments include, among others, cash and cash equivalents, exchange traded funds, hedge funds, real estate investment trusts, and
direct investments of private real estate and private equity. Exchange traded funds, such as gold, and real estate investment trusts are valued based on the closing price reported in an active market on which the investments are traded, and
therefore, are included in Level 1. Direct investments of private real estate and private equity are valued by investment managers based on the most recent financial information available, which typically represents significant unobservable
data. As such, these investments are generally classified as Level 3. 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 AWAC believes the valuation methods used by the plans trustee 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.

The following tables
present the fair value of pension and postretirement plan assets classified under the appropriate level of the fair value hierarchy:

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.

The total deferred
tax asset (net of valuation allowance) is supported by taxable temporary differences that reverse within the carryforward period (approximately 22%), and projections of future improvements in taxable income exclusive of reversing temporary
differences (approximately 78%).

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 the Companys experience with similar operations. Existing favorable contracts and the ability to sell product 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 the utilization of the 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 realizable in future periods, resulting in a future charge to record 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 December 2011, AWA Brazil applied for a tax holiday related to its expanded mining and refining operations. During 2013, the
application was amended and re-filed. If approved, the tax rate for this subsidiary will decrease significantly, resulting in future cash tax savings over the 10-year holiday period (would be retroactively
effective as of January 1, 2013). Additionally, the net deferred tax asset of the subsidiary would be remeasured at the lower rate in the period the holiday is approved. This remeasurement would result in a decrease to the net deferred tax
asset and a noncash charge to earnings of approximately $50.0. As of December 31, 2013, AWA Brazils application is still pending.

The following table details the changes in the valuation allowance at December 31:

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 (1) market participant assumptions developed based on market data obtained from independent
sources (observable inputs) and (2) 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.
| | ------- | --------------------------------------------------------------------------------

The following section describes the valuation methodologies used by AWAC to measure derivative contracts at fair value, including an indication of the level in the fair value hierarchy in which each
instrument is generally classified. Where appropriate, the description includes details of the valuation models, the key inputs to those models, and any significant assumptions. These valuation models are reviewed and tested at least on an annual
basis.

Derivative contracts are valued using quoted market prices and significant other observable and unobservable inputs.
Such financial instruments consist of aluminum, energy, and foreign exchange contracts. The fair values for the majority of these derivative contracts are based upon current quoted market prices. These financial instruments are all exchange-traded
and are classified within Level 1 or Level 2 of the fair value hierarchy as the quotations are deemed to be an active market.

For certain derivative contracts whose fair value is based upon trades in liquid markets, such as aluminum options embedded within supply contracts, valuation model inputs can generally be verified and
valuation techniques do not involve significant management judgment. The fair value of such financial instruments are generally classified within Level 2 of the fair value hierarchy.

AWAC has other derivative contracts that do not have observable market quotes. For these financial instruments, management uses
significant other observable inputs. 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. 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 level classification (1 or 2) in the period of such change.

As reflected in the table above, the net unrealized gain on derivative contracts using Level 3
valuation techniques was about $327.7 and $532.7 as of December 31, 2013 and 2012, respectively. These gains were mainly attributed to embedded derivatives in power contracts.

In July 2012, as provided for in the arrangements, management elected to modify the pricing for two existing power contracts, which
end in 2014 and 2016 (see directly below), for AWACs two smelters in Australia. These contracts contain an LME-linked embedded derivative, which previously was not recorded as an asset in AWACs Combined Balance Sheet. Beginning on
January 1, 2001, all derivative contracts were required to be measured and recorded at fair value on an entitys balance sheet under GAAP; however, an exception existed for embedded derivatives upon meeting certain criteria. The LME-linked
embedded derivative in these two contracts met such criteria at that time. Managements election to modify the pricing of these contracts qualifies as a significant change to the contracts thereby requiring that the contracts now be evaluated
under derivative accounting as if they were new contracts. As a result, AWAC recorded a derivative asset in the amount of about $583.3 with an offsetting liability (deferred credit) recorded in Deferred credit related to derivative contracts,
current and noncurrent. Unrealized gains and losses from the embedded derivative were included in Other (income) expense, net on the accompanying Combined Statements of (Loss) Income, while realized gains and losses were included in Cost of goods
sold on the accompanying Combined Statements of (Loss) Income as electricity purchases are made under the contracts. The deferred credit is recognized in Other (income) expense, net on the accompanying Combined Statements of (Loss) Income as power
is received over the life of the contracts. 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 decrease to the embedded
derivative asset.

Also, included within Level 3 measurements is a derivative contract that will hedge the anticipated
power requirements at AWACs Portland smelter in Australia once the existing contract expires in 2016. This derivative hedges forecasted power purchases through December 2036. Beyond the term where market information is available,
management has developed a forward curve, for valuation purposes, based on independent consultant market research. The effective portion of

gains and losses on this contract was recorded in Other comprehensive loss on the accompanying Combined Balance Sheet until the designated hedge period begins in 2016. Once the hedge period
begins, realized gains and losses will be recorded in Cost of goods sold. Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Higher prices in the power market would cause the derivative
asset to increase in value. AWAC had a similar contract for its Point Henry smelter in Australia once the existing contract expires in 2014, but elected to terminate the new contract in early 2013. This election was available to AWAC 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 as the contract for the Portland smelter.

Additionally, AWAC has a six-year natural gas supply contract, which has an LME-linked ceiling. This contract 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. Unrealized gains and losses from this contract were included in Other (income) expense, net on the accompanying Combined Statements of (Loss) Income, while realized gains and losses
will be included in Cost of goods sold on the accompanying Combined Statements of (Loss) Income as gas purchases are made under the contract.

Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the
derivative is reported as a component of other comprehensive (loss) income (OCI) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing
either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

Aluminum and Energy

AWAC anticipates the continued requirement to purchase aluminum and certain other commodities, such as electricity and natural gas, for its operations. AWAC enters into forwards and option contracts to
reduce volatility in the price of these commodities.

Interest Rates

An investment accounted for on the equity method by AWAC has entered into interest rate contracts, which are designated as cash flow
hedges. AWACs share of the activity of these cash flow hedges is reflected in the table above.

Foreign Exchange

AWAC is subject to exposure from fluctuations in foreign currency exchange rates. Contracts may be used from time to time to
hedge the variability in cash flows from the forecasted payment or receipt of currencies other than the functional currency.



AWAC had the following outstanding forward and option contracts that were entered into to hedge forecasted transactions:

entered into to minimize AWACs price risk related to certain electricity pricing arrangements.

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 AWACs control and could vary significantly from those factors disclosed.

AWAC 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, AWAC 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.

Other Financial Instruments

The carrying values and fair values of AWACs financial instruments at December 31 were as follows:

The following methods were used to estimate the fair value of other financial
instruments:

Cash and Cash Equivalents and Short-Term Borrowings

The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash
equivalents were classified in Level 1 and Short-term borrowings were classified in Level 2.

Notes Receivable

The fair value of notes receivable is based on anticipated cash flows which approximates carrying value and was
classified in Level 2 of the fair value hierarchy.

Long-Term Debt

The fair value of long-term debt is based on anticipated cash flows which approximates carrying value and was classified in Level 2
of the fair value hierarchy.

O. Contingencies and Commitments

Contingencies

Litigation

Alba Civil Suit

On February 27, 2008, Alcoa received notice that Alba had filed suit against Alcoa, 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 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.

In response to a motion filed by the U.S. Department of Justice (DOJ) on March 27, 2008 (see Government
Investigations below), the Court ordered the Alba civil suit administratively closed and stayed all discovery to allow the DOJ to fully conduct an investigation. On November 8, 2011, at Alcoas request, the Court removed the case
from administrative stay and ordered Alba to file an Amended Complaint by November 28, 2011, and a RICO Case Statement 30 days thereafter for the limited purpose of allowing Alcoa to move to dismiss Albas lawsuit. Alcoa filed a motion to
dismiss, which was denied on June 11, 2012.

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 $85.0 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, AWA recorded a $40.0 charge in addition to the $45.0 charge it recorded in the 2012 second quarter
in respect of the suit.

Government Investigations

On February 26, 2008, Alcoa Inc. advised the DOJ and the 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 and
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 $103.0 Based on this offer, AWA recorded a charge of $103.0 in the six months ended June 30, 2013. Also in the six
months ended June 30, 2013, Alcoa exchanged settlement offers with the SEC. However, the SEC staff rejected Alcoas offer of $60.0 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 $223.0, including a fine of $209.0 payable in five equal installments over four years. The first installment of $41.8, plus a one-time administrative forfeiture of $14.0,
will be paid in the first quarter of 2014 (paid on January 22, 2014), and the remaining installments of $41.8 each will be paid in the first quarters of 2015-2018. 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 $175.0, but will be given credit for the $14.0 one-time forfeiture payment,
which is part of the DOJ resolution, resulting in a total cash payment to the SEC of $161.0 payable in five equal installments over four years. The first installment of $32.2 will be paid to the SEC in the first quarter of 2014 (paid on
January 22, 2014), and the remaining installments of $32.2 each will be paid in the first quarters of 2015-2018.

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, AWA recorded a $288.0 charge, which includes legal costs of $7.0, in addition to the $103.0 charge it recorded in the 2013
second quarter in respect of the investigations. The $88.0 million paid in the first quarter 2014 is recorded in Other current liabilities in the Combined Balance Sheet.

On April 23, 2004, St. Croix Renaissance Group, L.L.L.P. (SCRG), Brownfield Recovery Corp., and Energy Answers Corporation of Puerto Rico (collectively referred to as Plaintiffs) filed a
suit against St. Croix Alumina L.L.C. and Alcoa World Alumina, LLC (collectively referred to as Alcoa)

case to federal court and after a several year period of discovery and motion practice, a jury trial on the matter took place in St. Croix from January 11, 2011 to January 20, 2011. The jury returned a verdict in favor of Plaintiffs and
awarded damages as described: on a claim of breaches of warranty, the jury awarded $13.0; on the same claim, the jury awarded punitive damages in the amount of $6.0; and on a negligence claim for property damage, the jury awarded $10.0. Plaintiffs
filed a motion seeking pre-judgment interest on the jury award. On February 17, 2011, Alcoa filed post-trial motions seeking judgment notwithstanding the verdict or, in the alternative, a new trial. On May 31, 2011, the court granted
Alcoas motion for judgment regarding Plaintiffs $10.0 negligence award and denied the remainder of Alcoas motions. Additionally, the court awarded Plaintiffs pre judgment interest of $2.0 on the breach of warranty award. As a
result of the courts post-trial decisions, Alcoa recorded a charge of $20.3 in 2011 (Note R). On June 14, 2011, Alcoa filed a notice of appeal with the U.S. Court of Appeals for the Third Circuit regarding Alcoas denied
post-trial motions. On June 22, 2011, SCRG filed a notice of cross appeal with the Third Circuit Court related to certain pre-trial decisions of the court and of the courts post-trial ruling on the negligence claim. The Third Circuit
Court referred this matter to mediation as is its standard practice in appeals. Following mediation and further, separate settlement discussions, the parties executed an agreement dated September 30, 2011 resolving the matter in its entirety,
and subsequently jointly petitioned (i) the District Court to release Alcoa from the jury verdict and (ii) the Third Circuit Court of Appeals to dismiss the matter. On March 13, 2012, the District Court entered an order discharging
Alcoa from the jury verdict and, on March 14, 2012, the Third Circuit Court of Appeals dismissed the matter. This matter is now fully resolved.

Other

In March 2013, Alcoa World Alumina Brasil (AWAB), was
notified by the Brazilian Federal Revenue Office (RFB) that approximately $110.0 (R$220.0) of value added tax credits previously claimed are being disallowed and a penalty of 50% assessed. Of this amount, AWAB received $41.0 (R$82.0) 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. The
assessment is currently in the administrative process, which could take approximately two years to complete. AWAB presented defense of its claim to the RFB on April 8, 2013. If AWAB is successful in the administrative process, the RFB would
have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a judicial level. The estimated range of reasonably possible loss is $0.0 to $65.0 ($R155.0), whereby the maximum end of the range represents the sum of
the portion of the disallowed credits applicable to the export sales and a 50% penalty of the gross amount disallowed. Additionally, the estimated range of disallowed credits related to AWABs fixed assets is $0.0 to $75.0 (R$175.0), 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.

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

Pursuant to the terms of the Formation Agreement, Alcoa and Alumina Limited have agreed to remain liable for Extraordinary Liabilities (as
defined in the agreement) as well as for certain other preformation liabilities, such as existing environmental conditions, to the extent of their preformation ownership of the company or asset with which the liability is associated.

Commitments

In October 2004, AWAC agreed to acquire a 20% interest in a consortium formed to acquire the DBNGP in Western Australia in exchange for an initial cash investment of $17.0. 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. AWAC has made additional contributions of $140.8 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 capital structure. This plan requires AWAC to contribute $40.0, of which $11.0 and $12.7 was made in 2013 and 2012, respectively. In addition to its equity ownership, AWAC has an agreement to purchase gas transmission
services from the DBNGP. At December 31, 2013, AWAC has recorded a noncurrent asset of $315.0 representing prepayments made under an agreement for future gas transmission services. AWACs maximum exposure to loss on the investment and
related contract is approximately $444.7 as of December 31, 2013.

In connection with the sale of Alcoa Specialty
Chemicals (ASC), in 2004 AWAC entered into a 20 year agreement to supply ASC with approximately 488,000 tons of alumina feedstock annually. The first five years of the contract provide for a fixed price with adjustments in
pricing to the extent certain AWAC costs fluctuate outside of agreed upon thresholds. In years six through ten pricing is tied to an industry-accepted index, and in the final ten years the pricing is to be negotiated.

AWAC has entered into other purchase commitments for energy, raw materials, freight and other goods and services which total $1,670.0 in
2014, $1,234.2 in 2015, $1,094.6 in 2016, $1,041.7 in 2017, $957.1 in 2018 and $5,667.1 thereafter.

AWAC has outstanding
letters of credit primarily related to environmental and leasing activities. The total amount committed under these letters of credit, which expire at various dates, mostly in 2013, was $5.7 at December 31, 2013. AWAC also has outstanding bank
guarantees related to legal, customs duties, environmental, and leasing obligations, among others. The total amount committed under these guarantees, which expire at various dates, was $95.2 at December 31, 2013.

AWAC has outstanding surety bonds primarily related to customs duties. The total amount committed under these bonds, which automatically
renew or expire at various dates, mostly in 2013, was $0.7 at December 31, 2013.

P. Environmental Matters

AWAC continues to participate in environmental assessments and cleanups at a number of locations. A liability is recorded for environmental remediation costs or damages when a cleanup program becomes
probable and the costs or damages can be reasonably estimated. See Note A for additional information. As assessments and cleanups proceed, the liability is adjusted based on progress in determining the extent of remedial actions and related
costs and damages. The liability can change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements and technological changes. Therefore, it is not possible to determine the outcomes or estimate
with any degree of accuracy the potential costs for certain of these matters.

AWACs remediation reserve balance at the
end of 2013 and 2012 was $9.8 and $12.3, respectively, and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Of the $9.8 reserve at December 31, 2013, $1.8 is
classified as current on the combined balance sheet.

Q. Restructuring and Other Charges

Restructuring and other charges were $431.5, $93.1 and $52.9 during 2013, 2012 and 2011, respectively. In 2013, $384.0 of the charge
related to the Alba Settlement (Note O), $30.2 related to goodwill impairment (Note A), $13.1 related to the asset impairment in Australia, and the majority of the remainder related to severance. In 2012, $85.0 of the charge was for the
Alba Settlement, and the majority of the remainder was for severance costs, primarily in Point Henry. In 2011, $20.3 was recorded for the St. Croix remediation settlement (Note O), $14.1 was recorded as an asset impairment for the permanent
shut down of an Australian spent pot lining processing facility, and $18.1 was recorded for severance charges, primarily related to Australia actions.

During 2011, the sale of Hotham Farm in Australia resulted in a gain of approximately $42.9.
Additionally, in 2011 equity income included higher earnings of $24.0 from the DBNGP investment in Australia due to the recognition of a discrete income tax benefit by the consortium.

S. Subsequent Events

In January 2014, the Company resolved the Alba matter that existed as of December 31, 2013 (see Government Investigations under Litigation in Note P).

In February 2014, the Company announced it will permanently close its Point Henry aluminum smelter in Geelong, Australia. The smelter will
close in August 2014, which will reduce Alcoas global smelting capacity by 190,000 metric tons. Total restructuring-related charges associated with the closure is expected to be $265.0 after-tax.

The combined financial statements of AWAC are derived from the financial statements of Alcoa, which were issued on February 13, 2014.
Accordingly, AWAC management has evaluated transactions for consideration as recognized subsequent events in the annual financial statements through the date of February 13, 2014. Additionally, AWAC has evaluated transactions that occurred as
of the issuance of these combined financial statements, March 4, 2014, for purposes of disclosure of unrecognized subsequent events.
