THE DEMERGER

On December 11, 2002, Alumina Limited (formerly known as WMC Limited) demerged its interest
in the Alcoa World Alumina and Chemicals joint venture (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 (Alumina) holds the interest in AWAC, and WMC Resources Ltd, which prior to the demerger was a wholly owned subsidiary
of WMC Limited, holds the nickel, copper/uranium and fertilizer businesses and exploration and development interests previously held within the WMC Limited group.

On June 4, 2005 WMC Resources Ltd was acquired by BHP Billiton Limited, of which it is now a wholly owned subsidiary.

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. 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, 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 the AWAC joint venture 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. Such variations, if
materially adverse, may impact 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 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.

KEY INFORMATION

ITEM 3. KEY INFORMATION

A. Selected Financial Data

A-IFRS

The selected financial data
appearing below as at December 31, 2006 and 2005 and for the fiscal years ended December 31, 2006, 2005 and 2004 are set forth in Australian dollars (except as otherwise indicated), and are extracted from the audited Consolidated Financial
Statements of Alumina Limited (the Company or Alumina , which, unless the context otherwise requires, includes Alumina Limited and its subsidiaries) which appear elsewhere herein.

The Consolidated Financial Statements for the years ended December 31 2006, 2005 and 2004 have been prepared in accordance with International
Financial Reporting Standards as adopted by Australia (A-IFRS) which differ in certain respects from accounting principles generally accepted in the United States (US GAAP).

US GAAP

As discussed above US
GAAP and A-IFRS differs in certain respects. Note 32 to the Consolidated Financial Statements provides an explanation of these differences as they affect Alumina, and reconciliations from A-IFRS to US GAAP of net income for the years ended December
31, 2006, 2005 and 2004 and shareholders equity as of December 31, 2006 and 2005.

The selected financial data under US GAAP
appearing below as at December 31, 2004, 2003 and 2002 and for the fiscal years ended December 31, 2003 and 2002 have been reconciled to US GAAP from Aluminas audited consolidated financial data, which are not included herein.

Equity Accounting

Equity accounting
is used where the consolidated entity exercises significant influence, but not control, over an investee company (the associate). Under this method, the consolidated entitys share of the post-acquisition profits or losses of associates is
recognized in the consolidated statement of financial performance, and its share of post-acquisition movements in reserves is recognized in consolidated reserves. The cumulative post acquisition movements are adjusted against the cost of the
investment. Aluminas Consolidated Financial Statements are currently prepared in accordance with A-IFRS. The financial statements of Alcoa World Alumina and Chemicals (AWAC), of which Alumina owns 40% of the assets, are prepared in
accordance with US GAAP.

The principal differences between A-IFRS and US GAAP which affect Aluminas net income for continuing
operations and comprehensive income, as well as its shareholders equity, either directly or through its share of associates on a continuing basis, relate to the treatment of the following items.



|(1) | fair value of accounting for derivatives;
|--- | -----------------------------------------



|(2) | goodwill and amortisation;
|--- | --------------------------



|(3) | asset retirement obligations and
|--- | --------------------------------



|(4) | pension liabilities/assets.

KEY INFORMATION

D. Risk Factors

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

AWACs revenue is derived from sales of alumina, alumina-based chemicals and aluminium. The price that can be obtained for these commodities is influenced by the price of aluminium in the world market, and in particular, the LME price
of primary aluminium. World aluminium prices are affected by numerous factors outside Alumina Limiteds control, including the overall performance of world economies and the related cyclicality in particular industries that are significant
consumers of aluminium.

The development of new alumina refineries and aluminium smelters, and increased production by new or existing
alumina and aluminium producers may create overcapacity, which could reduce future prices of alumina, alumina-based chemicals and aluminium, thereby adversely affecting AWACs, and hence Alumina Limiteds, profitability.

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

Alumina does
not separately hedge its exposure to aluminium prices. The Company expects that volatility in prices and demand for AWACs products will continue for the foreseeable future. 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 the
A$/US$ exchange rate can have a significant effect on earnings and profitability.

Alcoa of Australia contributes the majority of
AWACs earnings. While a significant proportion of Alcoa of Australias costs are incurred in A$, sales are denominated in US$. AWACs future profitability, as expressed in A$, and hence that of Alumina Limited may be adversely
affected by a strengthening of the A$ against the US$. AWACs profitability may also be adversely affected by a strengthening against the US$ of other currencies in which operating or capital costs are incurred by AWACs refineries outside
Australia.

In the past, AWAC entered foreign exchange hedging contracts to manage its exposure to the US$/A$ exchange rate with those
hedging contracts closing in 2003. Throughout the reporting period, and at balance sheet date, AWAC had no foreign exchange hedging contracts.

In addition, certain of the Companys liabilities and assets are denominated in US$, particularly much of the borrowings and certain equity accounted assets. The accounts of certain foreign subsidiaries are also maintained in US$. Thus
a change in the A$/US$ exchange rate would have an effect on the net asset value of the Company.

Fluctuations in the A$/US$ exchange rate
will affect the US$ equivalent of the A$ price of the Companys ordinary shares on the Australian Stock Exchange (ASX) and, as a result, are likely to affect the market price of the Companys American Depositary Receipts
(ADRs) in the United States. Such fluctuations would also affect the US$ amounts received by holders of ADRs on conversion of cash dividends paid in A$ on the Ordinary Shares underlying the ADRs. Alumina is not currently hedging its
currency exposures. See Item 11 Quantitative and Qualitative Disclosure about Market Risk.

An increase in AWACs production costs
could reduce Aluminas profitability.

Changes in AWACs costs have a major impact on the Companys profitability.
AWACs mining, refining and smelting operations are subject to conditions beyond its or Alumina Limiteds control that can delay deliveries or increase costs for varying lengths of time. These conditions include weather and natural
disasters, unexpected maintenance or technical problems, key equipment failures, disruptions to or other problems with infrastructure, variations in geological conditions and increases in the cost of key inputs or the non-availability of key inputs.
In addition, industrial disruptions, work stoppages, refurbishments and accidents at operations can result in production losses and delays in the delivery of product, which may adversely affect profitability. A key risk in the cost of production of
alumina and aluminium is the cost of energy. Increases in world oil and gas prices will increase the cost of production of alumina. Further key risks associated in the cost of production of alumina are the sourcing of bauxite and the volatile price
of caustic soda. Approximately 1 tonne of caustic soda is used for every 13 tonnes of alumina produced. Accordingly, an increase in caustic soda prices has the potential to reduce profitability.

KEY INFORMATION

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.

Changes to sales agreements could adversely affect Alumina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 agreements 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.

Availability of bauxite.

AWACs production of
alumina is dependant upon continuing availability of bauxite supply. AWAC obtains bauxite from bauxite resources to which it has access under mining leases and under short term and long term contracts. AWACs present sources of bauxite are
sufficient to meet the forecasted requirements of its alumina refining operations for the foreseeable future.

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

Governments extensively regulate AWACs mining 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 operations. 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 curtailment of operations. This relates particularly to environmental regulations.

The possibility exists that new legislation or regulations may be adopted which may materially adversely affect AWACs mining
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.

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

AWAC operates in a number of
countries, some of which have a higher political risk than Australia. Political activities in these countries may be destabilising 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 material adverse impact, such as the closure of an operation.

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 reserves, recovery rates, production rates, capital and operating costs and future commodity
prices and exchange rates.

Capital costs for development of alumina refinery and other mineral resource projects have increased
substantially in recent years, due to higher steel and other raw material prices and significant increase in labour and contractor costs. In particular, shortages of skilled labour due to an increase in the number of mineral resource project
developments, including in Australia and Brazil, has resulted in cost increases for the development of projects in those

locations. Also, the US dollar has fallen in value against currencies such as the Australian
dollar, the Euro and Brazilian Real. Where development projects, such as AWACs Alumar and Juruti projects, incur labour and material costs in the currency of the project country, a weaker US dollar results in a higher project cost in US dollar
terms.

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 Alcoa of Australias operations. Court
decisions and various pieces of legislation make it evident that there are complex legal and factual issues affecting existing and future Alcoa of Australia 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 cash flows depend on the availability of dividends from AWAC

Alumina Limiteds cash flows will be generated, primarily from distributions made by AWAC, by way of dividend or capital return. The Strategic Council 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 the entities comprising AWAC, unless the Strategic Council agree by a super majority vote to pay a smaller dividend.

During 2006 the AWAC partners entered a new funding agreement under which future capital expenditure 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.
The funding agreement is expected to largely eliminate the risk identified above, during the five year term of the funding agreement, of Alumina Limited being constrained in its ability to pay franked dividends to its shareholders.

The AWAC joint venture decides certain matters by an 80% supermajority vote (refer Item 10). 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 could occur that AWAC decisions by majority vote are not in the best interests of Alumina Limited.

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

AWAC may make an annual capital request of the partners of up to US$1 billion following approval by a majority vote of AWACs Strategic Council. Alcoa has a majority of the votes on the AWAC Strategic Council.
Alumina Limited is required to fund its share of the request subject to the provisions of the agreement. If Alumina Limited is unable or unwilling to obtain equity or debt funding or has insufficient retained earnings (ie cash) to make this capital
contribution, 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 an AWAC capital request made unilaterally by Alcoa, in the future, and that its
interest in AWAC could be diluted.

Constraints on availability of highly trained employees could have an adverse impact on AWACs operations

AWAC manages its business with a number of key personnel, the loss of whom could have a material adverse effect on its business.
AWACs, and hence Alumina Limiteds, future success will depend on AWACs continued ability to attract and retain highly skilled and qualified personnel. There can be no assurance that key personnel will continue to be employed by
AWAC or that AWAC will be able to attract and retain qualified personnel in the future. Failure to retain or attract key personnel could have a material adverse effect on AWACs, and hence Alumina Limiteds, business. These same issues
exist with respect to Alumina Limiteds key personnel, the loss of whom could have a material adverse effect on Alumina Limiteds business and its ability to manage its joint venture interests in AWAC.

ITEM 4. INFORMATION ON THE COMPANY

A. History and Development of the Company

Alumina Limited, previously called WMC Limited until its name change in December 2002 as part of the demerger, was incorporated in 1970. The demerger was
effected through an Australian court-approved scheme of arrangement and associated capital reduction and dividend distribution. In 1979 it became the holding company of the WMC Group which commenced operations in 1933. The Company is listed on the
Australian Stock Exchange. At December 31, 2006, Alumina had total consolidated assets of A$2.4 billion. Aluminas income from continuing operations was A$511.1 million in the year ended December 31, 2006 and A$315.6 million in the
year ended December 31, 2005.

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s ADRs should be addressed to its depositary, The Bank of New York, telephone +1 (212) 815 2293 or facsimile +1 (212) 571 3050, located at 101 Barclay Street, New York, NY 10286.

Following the demerger, Alumina Limiteds primary assets comprised the interests in the AWAC joint venture with Alcoa, Inc. AWAC has interests in
bauxite mining, alumina refining and two operating aluminium smelters. Coincident with the demerger, WMC Limited changed its name to Alumina Limited and has maintained its listings on the ASX and the NYSE.

Capital and Investment Expenditures

Since January 1, 2003 the continuing operations of Alumina made the following principal capital and investment expenditures:



| |  |  | In December 2003, Alumina increased its interest in Alcoa of Australia to 40% through purchasing QBE Limiteds 0.75% interest by issuing 18,372,881 shares in
Alumina. The acquisition was accounted for based on Aluminas closing share price on December 12, 2003 of A$5.90 (the closing price on the trading day prior to the date when the purchase was agreed).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2004, AWAC completed the sale of the Specialty Chemicals division, resulting in an after-tax profit of A$15 million for Alumina Limited. The sale was consistent
with AWAC directing its focus toward expanding its alumina operations.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In December 2004, Alumina Limited acquired, at a cost of US$40 million, a 40 per cent interest in the Juruti bauxite deposit in Brazil which is being developed
to supply bauxite to the planned expansion of the Alumar refinery and other AWAC or third-party refineries.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During 2005, Alcoa of Australia declared a special fully franked dividend of A$800 million (Alumina Limited share A$320 million), all of which was immediately
subscribed to Alcoa of Australia for the purchase of new shares.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During 2006, Alumina Limited contributed A$259.2 million to fund AWAC expansion projects in Brazil and Jamaica. A new bauxite mine is being developed in Brazil at
Juruti, a large high-quality bauxite deposit.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the four months to April 2007, Alumina Limited contributed a further A$153.5 million to fund the AWAC expansion projects in Brazil and Jamaica. Further
contributions to fund these projects will be made during the course of 2007.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

B. Business Overview

Aluminas sole business is participating in the global 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 per cent investment in AWAC. Aluminas primary asset is its 40%
interest in AWAC. A discussion of AWACs business is set forth below.

Alcoa World Alumina and Chemicals (AWAC) was formed
on January 1, 1995 by Alumina and Alcoa Inc. (Alcoa) combining their respective bauxite, alumina and alumina-based chemicals businesses and investments and some selected smelting operations. AWAC is the worlds largest producer
of alumina. Alumina and Alcoa own 40% and 60% respectively of Alcoa of Australia Ltd (AofA) and the other AWAC entities.

The
Strategic Council is the principal forum for Alcoa and Alumina to provide direction and counsel to the AWAC entities in respect of strategic and policy matters. The Alcoa and Alumina 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 (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 US$1 billion; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | loans to Alcoa, Alumina or their affiliates by AWAC entities (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.

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 is entitled to representation in proportion to its ownership interest on the Board of each entity in the AWAC structure, including Alcoa of Australia. Alumina has proportional representation on the Boards of
the following strategic AWAC companies: Alcoa of Australia and Alcoa World Alumina LLC. In addition to the Strategic Council meetings, Aluminas management and Board visit and review a number of AWACs operations each year.

Subject to the provisions of the AWAC agreements, AWAC is the exclusive vehicle for the pursuit of Alumina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.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

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

In November 2001, Alcoa announced that it had finalized agreements for a strategic alliance with the Aluminium Company of China Limited (Chalco). Under the strategic alliance, it was proposed that Alcoa and Chalco
would form a 50/50 joint venture in respect to Chalcos operations at Pingguo, which includes bauxite, alumina and aluminium facilities. In April 2004, approval was received from the China National Development and Reform Commission (NDRC) to
proceed with formation of their proposed joint venture. The Pingguo joint venture includes an alumina refinery and bauxite mining operations. Following successful completion of negotiations, AWAC would be offered participation in the bauxite mining
and alumina refining operations at Pingguo.

AWAC completed two significant refinery growth projects in the last two years. A further three
projects are underway, and feasibility studies have commenced for additional projects. AWACs Suralco and Pinjarra refineries have increased production capacity at a time of strong global alumina demand and prices. The progress of AWACs
expansion projects through the approval and development phases will depend upon growth in market demand. The Pinjarra alumina refinery upgrade in Western Australia was completed in the first half of 2006 at a capital cost of US$510 million. The
upgrade at Pinjarra added 657,000 tonnes of production capacity per annum, increasing total capacity to 4.2 million metric tonnes per year (mtpy).

A 146,000 mtpy capacity expansion of Jamalco alumina refinery in Jamaica was completed in the first quarter of 2007. A second phase expansion of 1.35 million mtpy has been deferred pending the outcome of
negotiations of an agreement between the Jamaican and Trinidad Governments to bring natural gas to Jamaica and the Jamalco refinery, and changes to the joint venture agreement.

Construction of a 2.1 million mtpy expansion of the Alumar alumina refinery in Brazil by the consortium partners (AWAC, Alcoa Aluminio S.A., BHP
Billiton and Alcan), commenced in 2006. Total refinery capacity will increase to 3.5 million mtpy on completion of the expansion planned for the second half of 2008. AWAC has a 54 per cent interest in the expansion project, (1.1 million
mtpy).

A new bauxite mine is being developed in Brazil at Juruti, a high-quality bauxite deposit. A 100 per cent AWAC development,
the Juruti mine will initially produce 2.6 million tonnes of bauxite per year to supply AWACs share of the expanded Alumar facility. The initial 2.6 million tonne project includes infrastructure that supports further mine expansions.
Commissioning is schedule to commence during 2008.

AWAC, Alcan and the Government of Guinea signed a basic agreement that sets the
framework to develop a 1.5 mtpy alumina refinery in Guinea. A detailed feasibility study is expected to be completed in early 2008. AWAC has a longstanding involvement in bauxite production in Guinea through its 45 per cent equity interest in
Halco (Mining) Inc., which has a 51 per cent interest in Compagnie des Bauxites de Guinee.

AWAC signed a memorandum of understanding with
Vietnam National Coal  Minerals Group in March 2006 to explore the feasibility of creating a joint venture to develop a bauxite mine and alumina refinery in the Dak Nong Province in Vietnam.

The alumina production capacity at December 31, 2006 of AWAC is approximately 14.7 million tonnes per annum, comprised of Australian operations
 8.9 million tonnes; Point Comfort  2.3 million tonnes; San Ciprian  1.4 million tonnes; Suriname  1.2 million tonnes; Jamaica  0.6 million tonnes; and Brazil  0.3 million tonnes. In
the year ended December 31, 2006, AWAC produced approximately 14.3 million tonnes of alumina, compared with approximately 13.7 million tonnes of alumina the previous year, with seven refineries achieving annual production records.

AWAC does not designate bauxite deposits as
reserves. AWACs bauxite deposits are large resource areas with mining rights that expire in almost all cases more than 30 years from today. Furthermore, bauxite is found close to the earths surface and does not require extensive
processing to feed alumina refineries. Given the nature of how bauxite exists, the large size of AWACs bauxite resources, the abundant supply of bauxite globally and the length of AWACs mining rights, it is uneconomic for AWAC to incur
significant costs to establish bauxite reserves that reflect the size of the bauxite resources it has, and AWAC has determined that this would be an unnecessary expense.

AWAC mines bauxite in areas as described below. These mining operations extract bauxite which is located at shallow depths. Overburden is removed by heavy earthmoving equipment from small areas at a time, and bauxite
is extracted using similar equipment, in most cases with little or no requirement for explosives.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS



Bauxite mining is planned on an incremental basis. Detailed assessments are progressively undertaken of bauxite 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.

Bauxite deposits are not evaluated on a basis which could be described as a
cutoff grade. The suitability of any particular bauxite deposit for refining into alumina depends on a number of characteristics of the deposit. It is also a function of the development and application of technologies appropriate to the
specific chemical and physical characteristics of the material.

The most important characteristics in determining commerciality of a
deposit are the chemical nature of the bauxite; the proportion of available alumina in the bauxite; the depth and nature of the overburden; and the proximity of the deposit to a refinery location. A bauxite deposit close to a refinery
(or to a location at which a refinery can be constructed) may be commercial notwithstanding a relatively low percentage of available alumina. Only bauxite with a high percentage of available alumina (typically above 40%) is suitable for shipping
long distances. The available alumina in AWACs bauxite mines ranges from 35% to 50%.

The primary cash cost in the refining process,
after the cost of bauxite itself, is the energy required to generate process steam. Bauxite of gibbsitic chemical composition requires substantially less energy to refine than does diasporic bauxite (which requires higher temperature and pressure in
the digestions system, with the resulting energy consumption two to three times greater). Energy for the refining process can be sourced from natural gas, fuel oil or coal, and the local availability and price of such energy supplies influences the
relative economic attractiveness of a particular bauxite deposit.

Bauxite also contains various amounts of other minerals including silica
and iron, and of organic compounds. The presence of high levels of organics requires additional processing of the caustic liquor but does not prevent the bauxite being used as an alumina feedstock. High levels of silica generally result in greater
consumption of caustic soda in the refining process, so the price and availability of caustic soda at a particular location is also taken into account in assessing the attractiveness of any bauxite deposit.

Australia

Cape Bougainville  Mining Leases M80/47 to 60

Cape Bougainville is located in the Kimberley region of Western Australia. Access is via a poor access road from Wyndham, or by small
plane. Mining leases were issued to a consortium owned 67.5% by Mitchell Plateau Bauxite Co. (a wholly owned subsidiary of Comalco) with the remaining 32.5% owned by Alcoa of Australia. The mining leases grant rights to explore on the lease area for
a period of 21 years, expiring in September 2006. Current renewal applications are in progress. The Cape Bougainville bauxite deposits are lateritic plateau type. The group of deposits is composed of three major plateaus each about 23km square in
surface and 16 other plateaus of variable sizes. The geology is similar to that of the Mitchell Plateau (see below), derived from the Carson volcanics, a basic extrusive. These deposits have a medium to high available alumina content. Reactive
silica levels are moderate to high. No exploration work has been carried out on the mining leases since the late 1970s, partially due to ongoing negotiations and regulatory requirements in regard to the Indigenous Traditional Owners. The
original owner, AMAX, completed minor drilling from 1966 to 1972. No exploration has been undertaken since then. There are no infrastructure facilities and equipment of note. Costs have been included in Mitchell Plateau costs.

Mitchell Plateau Special Temporary Reserve (TR 5601H)

Mitchell Plateau is located in the Kimberley region of Western Australia. Access is via a poor access road from Wyndham, or by small plane. Mining leases were issued to a consortium owned 65.625% by Mitchell Plateau Bauxite Co. (a wholly
owned subsidiary of Comalco) with the remaining 34.375% owned by Alcoa of Australia. The mining leases grant rights to explore for and mine bauxite on the lease area. Granted on original condition that the mine would be developed, the Western
Australian Government has granted extensions to the original commencement date and is reviewing the latest extension request. The Mitchell Plateau bauxite deposits conform to the global classification of lateritic plateau type. They are residual
near surface in nature, gibbsitic and derived from the Carson volcanics, a basic extrusive. These deposits have a medium to high available alumina content. Reactive silica levels are moderate. No

exploration work has been carried out on the temporary reserve since the late 1970s and latest feasibility study concluded it was uneconomic to develop
at present. The original owner, AMAX, completed drilling from 1966 to 1972. Mitchell Plateau Bauxite Co. undertook some further limited drilling from 1973 to 1976. No exploration has been undertaken since then. There are no infrastructure facilities
and equipment of note. An airstrip for light planes is kept in a serviceable condition. Tenement rentals, administration and other basic requirements amount to approximately US$50,000 to US$100,000 per annum.

M.L. 1sa Darling Range Western Australia Special Agreement (bauxite only) Mining Lease

M.L. 1sa is approximately 7,000 square kilometres with the Darling scarp being its western margin, extending from the capital city of Perth south to the
town of Collie. Alcoa of Australia has exclusive rights to explore for and mine bauxite on the lease. Lease renewal will occur in 2045. State Government approval of annual Five Year Mine Plans and forest clearing boundaries, plus meeting established
rehabilitation standards, are conditions for ongoing mining operations. Darling Range bauxite deposits conform to global classification of lateritic pateau type. They are residual near surface in nature, gibbsitic and derived from Archean granites,
gneisses and Precambrian dolerite intrusives. By world standards, these deposits have low available alumina content. Reactive silica levels are also low. Currently, Alcoa of Australia has two operating mines (Huntly and Willowdale) on the lease,
supplying three refineries (Kwinana, Pinjarra and Wagerup). The annual mining rate is currently 37 mtpy of bauxite. Annual alumina production is 8.8 million tonnes. Approximately 75% of the lease has been explored by drilling. Annually, about 50,000
drill holes are programmed for reserve/resource definition. The infrastructure on the property consist of buildings for administration and services, mobile and fixed plant workshops, power, fuel and water supply amenities. Equipment located on the
property consists of mining production fleet of heavy equipment, mobile and fixed plant maintenance equipment, crushers and conveyors. The source of power is electrical from the refinery with diesel trucked in. Water is sourced from an owned dam
with back-up from state government water supply dams when required. Operating expenditure amounted to US$162.3 million and capital expenditure of US$10.2 million for 2006. About US$475 million cumulatively has been spent on exploration and
development to date.

Brazil

Juruti Regional
Exploration Area  Bauxite Exploration

Located in the Para and Amazonas. The nearest town is Juruti in the state of Para and
Nhamunda in Amazonas. Access in Para is by rural roads. In Amazonas access is by boat. Total of all exploration properties is 340,000 hectares. The surface is mainly owned by the Government of Brazil. AWAC has been granted exploration rights to 16
areas in the state of Para and 20 areas in the state of Amazonas. As a condition to maintain rights, periodic reporting of exploration results and activities is made to DNPM, the federal mining agency. The bauxite was developed during the Tertiary
(Eocene-Oligocene) from intense tropical weathering of Cretaceous fine to medium grain feldspathic sandstones of the Alto do Chao Formation within the Barreiras Series. The weathered profile is from top to bottom: 1. Belterra sandy clay; 2. Nodular
Bauxite (not considered ore, even though it may show good grades of A1203 av); 3. High iron laterite; 4. Bauxite, massive to friable to sugary in texture (this is the main ore zone); 5. Variegated clay. The contacts of all horizons are transitional.
The current status is exploration drilling activities for the discovery and evaluation of bauxite. Exploration drillings on various grid spacings have been accomplished to allow for the discovery and evaluation of bauxite resources with work
currently continuing. No permanent infrastructure or facilities have been established. Temporary exploration camps are in use. Equipment consists of exploration drills when drilling is in progress. No equipment is permanently located on these
properties. Source of power is derived from small portable generators used for the exploration camps. Water is available locally from streams. Approximately US$10 million has been spent in this region over the last 3 years (2004-2006) with similar
future planned costs.

development activities have been in progress with the aim of commencing mining operations by the second quarter of 2009, supplying 40% of plants
requirement. Individual potential bauxite ore bodies are being auger drilled on 30m spacing. Approximately 74% of the property has been explored. Development of the mining facility is presently on-hold. The source of power will tie into the regional
grid. Source of water is the local lakes and wells. Exploration expenditure of roughly US$3 million has been incurred over the last 3 years (2004-2006) in conjunction with North Manchester. Future capital expenditure costs of approximately US$100
million are planned for the development of North Manchester mines and access infrastructures.

Suriname

Nassau; Mining Property

Located in District of
Sipaliwini, Suriname with Langatabiki the nearest town. The size is approximately 8,200 hectares. The surface is owned by the Government of Suriname. Exploration rights are maintained by Suralco. A condition of maintaining rights is for the
development of a mine in the short term, included in the so called Eastern Sequence Mine Development. The Nassau area belongs to formations of the Marowijne Group which comprises of the Paramacca Formation, the Armina Formation and the
Rosebel Formation in this sequence from older to younger. Nassau is a plateaux or table mountain, and is dissected by the major creeks in four separate plateaux. The Nassau Mountains proper consists of rocks of the Paramacca Formation only. The
Plateaux A, B and C are primarily low metamorphosed basalt with some intercalations of coarse grained quartz-gabbros, some acid extrusives and very minor intercalations of quartzites. In plateau D more intercallations of acid extrusives and
metamorphosed sedimentary rocks such as schists and graywackes occur. This corresponds with the reconstructed (old) paleo Eocene pediplain on which probably all bauxite deposits of east Suriname were developed. The laterite capping protected the
Nassau area against rapid erosion; after uplift and subsequent erosion and denudation of the surrounding are the plateaus now rise from 500-570 meters above sea level. In areas around Nassau and especially on the west and south slopes of the
plateau, gold occurred and is worked by porknockers. No activities at present. Deposit has been under review for development by the Mining Joint Venture Suralco/BHP Billiton. Exploration work on a grid of 200 ft x 400 ft completed with over 4200
holes drilled. A number of additional exploration holes have also been drilled recently. Infrastructure on the property at present is a reconnaissance laterite capped road over the length of the deposit with a tertiary road connecting the Nassau
Hill with existing North-South secondary road. No equipment or power is located on the property. Source of water are the creeks over the plateaus. The Nassau deposit is considered not economically feasible at this time. No further development work
is planned.

Bakhuis; Mining Property

Located in District of Sipaliwini, Suriname with Apoera, Washabo the nearest town. Access is by the Nickerie River followed by a laterite capped road of about 70 km, or via a 250 km laterite capped road through Suriname. The Bakhuis horst
extends over 125 km in a NNE-SSW direction over a width of 35 km (437,500 ha). The surface is owned by the Government of Suriname. Indigenous communities have asserted traditional ownership rights. Current concession rights for the exploration of
the Bakhuis horst. Exploration license has elapsed and currently negotiation is ongoing to obtain an exploitation license. A condition of maintaining rights is for the development of an integrated bauxite industry in west Suriname. The Bakhuis area
consists of closely spaced hills up to 480 m in elevation. The geomorphology is characterized by a top plateau at 400 m with two to three lower levels, at altitudes ranging from 360 m down to about 250-220 m, marked with steep escarpments of
ferruginous laterite. Bauxite occurrences at Bakhuis are controlled to a large degree by the composition of the bedrock. Hence, bauxite occurs as it follows parent rocks with suitable composition on plateaus or slopes, almost irrespective of
geomorphology and elevation. These rocks, which form the Bakhuis horst, extend over 125 km in a NNE-SSW direction over a width of 35 km. Suitable rock types are medium grained leucogabbros, norites and banded granulites of the charnockite suite.
Banded granulites have varying compositions, the most common being noritic and enderbitic granulites. The peneplanation surfaces are frequently capped with laterite and bauxite, while slopes display occasional outcrops of parent rock. Most of the
bauxite occurs at levels ranging from 250 m to 450 m. High level bauxite, over 300 m elevation, is relatively low grade owing to the presence of hard caps, while bauxite at lower elevation, which is younger and located predominantly in slopes, is
richer in alumina and reactive silica. Bauxite in lower levels provides lesser tonnages than that of higher levels and offers less potential for increasing the amounts. The current status is that of a prospective mine, under

development managed by the Mining joint venture partner, BHP Billiton. Current infrastructure on the property consist of service roads, yards, shop, stores
and office facilities to support ongoing resource characterization and mine engineering work. Equipment consists of light trucks and equipment servicing vehicles. Fixed equipment comprises of shops, store buildings and offices. Diesel generators are
the source of power with portable water produced from the nearby creek as the source of water. Estimated cost of development of the mine is still unclear, due to issues related to conditions under which the Government will grant the requested
exploitation license, but order of magnitude cost including transport infrastructure will be in excess of US$500 million.

Kaimangrassie; Mining
Property

Located in the District of Para, with La Vigilantia the nearest town. Access is by the highway which is asphalt-paved, then by
haul road developed by the mine. The size is approximately 360 hectares. The surface is owned by the Government of Suriname. Current concession rights for the exploitation of the bauxite occurrence. A condition of maintaining rights is the mining of
the entire bauxite occurrence. The bauxite deposits result from the weathering of basement rocks and alluvium/colluvium derived from the basement. The bauxite is buried under 20 m to 50 m of post-Eocene sediments as a result of the basement downwarp
along a line roughly parallel to the present shoreline. The overburden consists of soft clays overlying hard clays with sand intercalations. The bauxite layer averages 5 m in thickness. While the upper part of the ore bed is generally ferruginous,
red-brown in color, compact and requires blasting, the lower part is predominantly grey in color, porous and softer. The top of ore is overlain by a thin transition zone, less than 50 cm, of hard clays or sand resting on a ferruginous hardcap, which
in general is easily identifiable. The bauxite floor consists of semi-indurated box-work bauxite or banded bauxite resting directly on basal clays. The bauxite contains gibbsite, haematite, goethite, kaolinite and quartz. Minor impurities include
anatase, sulphide in the form of marcasite and organics, reported respectively as TiO2, Corg and SO3. Klaverblad and Kaaiman Grassie are somewhat higher in Fe2O3 and lower in RSiO2, 7.3 - 9.8% and 3.2 - 3.8% respectively. Overburden thickness
averages 16 m in Klaverbald and 4 m only in Kaaiman Grassie. Current status is that of an active mine since 2006, under management of the joint venture partner, BHP Billiton. Exploration was completed on a grid of 200 feet by 200 feet. Supplemental
quality control drilling was also conducted. Current infrastructure on the property consists of mine haul roads, service roads, stockpile areas, shop, stores and office facilities. Most facilities are shared with the Klaverblad mine. Equipment
located on the property consists of loading equipment including hydraulic excavators, wheel loaders, track type tractors, light trucks, equipment servicing vehicles, lowboys, equipment maintenance shops, store buildings and offices. Diesel
generators are the source of power with portable water in water tanks as the source of water. Total costs incurred on this property to April 2007 combined with Klaverblad are approximately US$190 million.

the short term. The general geology of the area is similar to the Nassau Mountains. There are no current activities on the property. Exploration work
completed to date has been 663 exploration holes drilled on several plateaus of the Lely Mountains in the early 1970s. No work has been done since then. There is no infrastructure, equipment or power located on the property. The source of
water is from creeks over several plateaus of the Lely Mountains. Follow-up concept level study has concluded in 2006 that the deposits are not economically feasible at this time.

Lelydorp 3; Mining Property

Located in the District of Para, with Lelydorp; La Vigilantia is the
nearest town. Access is by the highway, which is asphalt-paved. The size is approximately 1,000 hectares. The surface is owned by the Government of Suriname. Current concession rights are for the exploitation of the bauxite occurrence. A condition
of maintaining rights is the mining of the entire bauxite occurrence. The bauxite deposits result from the weathering of basement rocks and alluvium/colluvium derived from the basement. The bauxite is buried under 20 m to 50 m of post-Eocene
sediments as a result of the basement downwarp along a line roughly parallel to the present shoreline. The overburden consists of soft clays overlying hard clays with sand intercalations. The bauxite layer averages 5 m in thickness. While the upper
part of the ore bed is generally ferruginous, red-brown in color, compact and requires blasting, the lower part is predominantly grey in color, porous and softer. The top of ore is overlain by a thin transition zone, less than 50 cm, of hard clays
or sand resting on a ferruginous hardcap, which in general is easily identifiable. In Lelydorp III, however, the top of the ore is more difficult to discern because of a widespread resilication of the upper part of the bauxite profile. The bauxite
floor consists of semi-indurated box-work bauxite or banded bauxite resting directly on basal clays. The bauxite contains gibbsite, haematite, goethite, kaolinite and quartz. Minor impurities include anatase, sulphide in the form of marcasite and
organics, reported respectively as TiO2, Corg and S O 3. Current status is that of an active mine which is being managed by the joint venture partner, BHP Billiton. Exploration was completed on a grid of 200 feet by 200 feet. Infrastructure on the
property consists of mine haul roads, service roads, stockpile areas, shop, stores, and office facilities.

Equipment located on the
property consists of a 1350W walking dragline, bucket wheel excavator with conveyors, off road haul trucks, 100 tonners, loading equipment, including hydraulic excavators, wheel loaders, track-type tractors, light trucks, equipment servicing
vehicles, lowboys, and equipment maintenance shops. Power is from the electrical network, and water is sourced from a portable distribution network. Mining activities have been stopped in February 2007 due to the depletion of the bauxite reserves.
The mine is in closure process.

Moengo Bauxite Deposits, Marowijne Concession Area; Mining Property

Located in the District of Sipaliwini, with Moengo the nearest town. Access is on the major east-west road along the coast. The size is approximately
32,000 hectares. The surface is owned by the Government of Suriname. Current concession rights are for the exploitation of the bauxite occurrence. A condition of maintaining rights is the continuing mining of all deposits up to depletion. The
typical profile of the bauxite occurrences in the Marowijne bauxite concession area consists of the following layers: cover layer, duricrust, bauxite, a transition zone and saprolite. The thin cover layer has an upper humic and a lower iron-rich
concretionary part. The layer is generally about 0.3 m thick, but in the valleys incising the bauxite deposits it may reach thickness up to 3 m. The duricrust has an average thickness of 0.5 to 2 m, is very hard and massive and has reddish to
brownish colour. The bauxite proper occurs underneath this and is up to 14 m thick, averaging about 4 m. It can be divided into upper, massive and compact bauxite with concretionary structure and a lower, more friable and less compact bauxite with
layered, cellular and concretionary structures. The transition zone to saprolite is rather irregular and appears to be a lensoid feature with variable thickness, extent and chemical characteristics. In this bauxite area the parent rocks cannot be
found as they are completely altered to bauxite.

The bauxite contains gibbsite, hematite, goethite, kaolinite and quartz. Minor impurities
include anatase and organics. Current status is that of bauxite mining under management by the joint venture partner, BHP Billiton. All exploration work is completed. Some drilling of the remnant areas is taking place to determine the amount of
remnant ore available to be mined. The mine is nearing its end of life. Infrastructure on the property consists of more than 30 km of haul roads, service roads and, stockpile areas; and a crusher plant, including shop and office. Equipment located
on the property includes off the road haul trucks, 100-toners, loading equipment, including hydraulic excavators, wheel loaders, track- type tractors, light trucks, equipment servicing vehicles, lowboys, crusher, and a powerhouse. Source of

power is via three 200KW diesel generators and water is sourced from a water plant producing portable water from a nearby river. The mine is nearing its end
of life and would be depleted by 2010.

Brownsberg: Mining property

Brownsberg is located 100 km South of the Paranam refinery and 25 km West of the Afobaka dam using an unpaved road. The Brownsberg includes two plateaus standing 400 m above sea level. Bauxite occurs in a geological
setting similar to that of Nassau and globally presents the same characteristics. The deposits are within a forest reserve, which restrict the use of the resources. Initial reconnaissance took place in 1914, but it is in 1968-69 only that Suralco
undertook systematic drilling with 4 Parmanco auger drills. A total of 1408 holes were drilled at 61 x 61 m intervals. Suralco performed check drilling in 2002 and 2003. There is no infrastructure, equipment or power located on the property.
No exploration or mining development is currently planned for this property.

Caramacca: Mining property

The Caramacca deposit is located approximately 7 km east from Kaimangrasi and 33 km by road to the refinery. The bauxite deposit is approximately 5m thick
and overlain by a 3 to 15m thick with very low to medium strength clays and sands. The Caramacca area has been investigated as far back as 1959 as a potential source of bauxite feed for the Paranam refinery. Several drilling campaigns have been
carried and most recently in 2006, infill core drilling lead to the definition to proven resources of about 3 millions tons. Equipments to be used for mining will include four 50 tons haul trucks and 1 excavator. Mine Site Infrastructure facilities
will consist of mine offices, a lunchroom and washroom facility at the mine site. The mine development currently underway includes a haul road to link this mine to the Kaimangrasi-Paranam main haul road and a open pit to mine the bauxite. First
delivery of bauxite is expected in early 2008 Total amount spent to complete the exploration and feasibility studies in 2004-2006 amounts to $US6.7 million. Expected total capital investment for mine development will be approximately $32 million.

Guinea

Boke; Mining Property

Located 150 km northeast of Guinea capital, Conakry, in Lower Guinea, the Boke mining operations are operated by Compagnie des Bauxites de Guinée
(CBG), owned 51% by Halco Mining (AWAC 45%; Alcan 45%; Dadco 10%) and 49% by the Government of Guinea. Boke bauxite is of blanket type, typical of Guinea bauxite deposits. It occurs close to the surface, requiring little overburden removal, at bench
heights of up to 8 m. Boke bauxite typically grades at average 51% available alumina. Approximately 85-90% of output is sourced from the Bidi Koum and Silidara deposits. Ore is mined by drilling, blasting and excavation, loaded by hydraulic
excavators onto haul trucks and transported to stockpiles. Blended bauxite is transported to the Kamsar port via company-owned railway, and loaded onto ships via a company-owned 1.6km jetty.

AWAC Operations

i) Smelter-Grade Alumina and Primary Aluminium

Australia

In Australia, AWAC
partners own 100% of Alcoa of Australia which operates integrated aluminium facilities, including mining, refining and smelting facilities. In calendar year 2006, the Australian operations produced 8.5 million tonnes of alumina (2005: 8.1 million
tonnes) and 377,351 tonnes of aluminium (2005: 377,259 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

OPERATING AND FINANCIAL REVIEW AND PROSPECTS



bauxite mines, each located in the Darling Ranges south of Perth, which supply AWACs three alumina refineries in Western Australia. Bauxite is transported by rail to the refinery at Kwinana, or by overland conveyor to the Pinjarra and
Wagerup refineries. The Kwinana, Pinjarra and Wagerup refineries have capacities of 2.1 million tonnes, 4.2 million tonnes and 2.5 million tonnes, respectively. An efficiency upgrade to the Pinjarra Refinery was completed during the second quarter
of 2006. This upgrade added 657,000 tonnes per annum of capacity. The planned capacity expansion of the Wagerup alumina refinery in Western Australia, by up to 1.8 million tonnes per year received Western Australian Government approval in September
2006. The expansion involves building a third production unit and upgrading existing plant and would provide additional alumina production at low cash operating costs. Detailed engineering and design work is being undertaken in 2007. A decision on
the expansion project is expected to be made in early 2008.

A storage and loading facility which handles the majority of shipping for the
Pinjarra and Wagerup refineries is located at the port of Bunbury near Wagerup. Some Pinjarra production is also shipped through the shipping 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 granted by the Western Australian Government expire in 2044.

AWAC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 low in alumina grade, is also low in reactive silica. This results in low consumption of caustic soda which in turn contributes to low 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 from 2005 through to 2020.

AWAC is
a 20% participant in the consortium that acquired the Western Australian Dampier to Bunbury Natural Gas Pipeline in 2004. Participation in this acquisition secured energy delivery capacity required to support further capacity growth in AWACs
Australian refining system.

AWAC also 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. AWACs interest in the Portland smelter increased from 45% to 55% in 2000 following the acquisition of Eastern Aluminiums 10% interest in
the smelter. The Portland smelter has an annual production capacity of 352,000 tonnes of aluminium and is approximately 240 kilometres west of Geelong. Point Henry has an annual capacity of 185,000 tonnes.

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.

Most electricity for the Point Henry smelter is supplied by Alcoa of Australia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.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

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 nominal capacity of 2.3 million tonnes per annum. In February 2001, AWAC announced the immediate reduction of the operating rate of Point Comfort to between 1.6
to 1.9 million tonnes per year. This rate was further reduced in the second half of 2001, to an operating rate of 0.7 to 0.8 million tonnes per year, in response to weak markets and high costs. During 2002 the production rate returned to a
rate of 1.8 million tonnes per annum. Point Comfort returned to producing at full capacity during the second quarter of 2003 (2.3 million tonnes per annum).

In November 2006 AWAC announced that production at Point Comfort would be reduced by approximately 17% as part of optimising AWACs global alumina production system.

Bauxite for the refinery is sourced from an AWAC affiliate in Guinea and is also purchased in the spot market from Jamaica and French Guiana. Point
Comfort uses gas-fired cogeneration facilities to supply process heat and power to the refinery, and gas is purchased from local suppliers using a mixture of short and medium-term contracts.

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 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) after incorporating Reynolds Metals Companys 6% interest in Halco into AWAC in December 2002. Halco is an international consortium that owns 51% of
Compagnie des Bauxites de Guinée (Compagnie Guinée), the manager of a number of bauxite mines at Boké in Guinea, West Africa. The Republic of Guinea owns the remaining 49% of Compagnie Guinee.

The Boké bauxite mines are located north-west of Conakry in Guinea.

The shareholders of Halco take bauxite in proportion to their equity positions under take-or-pay contracts. Long-term agreements to purchase bauxite mined by Compagnie Guinee expire after 2011. AWAC also purchases
bauxite from other Halco equity holders.

Other Guinea Interests

AWAC, Alcan and the Government of Guinea have signed a Basic Agreement that sets the framework to develop a 1.5 mtpy alumina refinery in Guinea. A detailed feasibility study is now expected to be completed in early
2008. AWAC has a longstanding involvement in bauxite production in Guinea through its 45 per cent equity interest in Halco (Mining) Inc., which has a 51 per cent interest in Compagnie des Bauxites de Guinee.

Suriname

Suralco

In Suriname, 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 the north of Suriname, was constructed in 1968 and sources bauxite from mines in
Suriname. The refinery is owned by a joint venture held 55% by Suralco and 45% by an affiliate of BHP Billiton plc (BHP Billiton). Suralco acts as manager of the joint venture and operates the refinery. The joint venture parties share
alumina production from the refinery in proportion to their shareholdings and are separately responsible for the marketing of their share of this production.

The Suralco refinerys current sources of bauxite, and additional bauxite supply from two successor mines, Kaimangrasie and Klaverblad in Eastern Suriname, will provide the refinery with domestic bauxite until
approximately 2010. AWAC and joint venture partner BHP Billiton are evaluating alternatives in Suriname for further long term bauxite supply from 2010, including from the Bakhuis region in Western Suriname.

In January 2003, AWAC and BHP Billiton signed a Memorandum of Understanding (MOU) with the government of Suriname providing for (i) continuation and
expansion of mining and refining activities in eastern Suriname and (ii) various exploration and other activities over the following two years relating to the feasibility of bauxite and alumina investments in western Suriname. Exploration
activities of the Bakhuis area in Western Suriname were completed in December 2005. The anticipated tonnages and qualities were confirmed. AWAC and BHP Billiton expect to begin negotiations for the bauxite resources with the government of Suriname
by the end of July 2007.

In August 2003, AWAC announced a 250,000 tonne expansion at the Paranam refinery (AWACs share 55%). The
US$65 million expansion was completed in February 2005.

AWAC and BHP Billiton have also signed an agreement extending the terms of their
existing joint venture agreement on bauxite mining and alumina refining in eastern Suriname to 2025.

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 Suriname Government.

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 50% by AWAC and 50% 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.

The bauxite mines that feed the refinery are located 40 kilometers to the north of the refinery in the Mocho Mountains. The bauxite mining rights are
owned by Jamalco. The bauxite mined in the Mocho Mountains is transported to the refinery on a railway 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. Bauxite is also sourced from leases in Harmons Valley and the Manchester Plateau.

Jamalcos alumina refinery,
completed in 1972, is located 72 kilometers west of Kingston. The refinerys nominal capacity was 1.25 million tonnes per annum after completion of the 250,000 tonne expansion in November

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

2003. The completion of the expansion was part of an agreement to
invest US$115 million to expand the refinery and remove from Jamalco the nearly 30-year-old levy on bauxite. The removal of the levy, along with the expansion, reduced operating costs by 30%.

The refinery produces smelter grade alumina, and production was higher in 2006 compared with production for 2005. 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 reached mechanical completion in the first quarter of 2007. As a result of 100% funding of the expansion, AWACs ownership
of Jamalco has increased to 55%.

A planned second phase expansion of 1.35 million mtpy has been deferred pending the outcome of
negotiations of an agreement between the Jamaican and Trinidadian governments to bring natural gas to Jamaica and the Jamalco refinery, and changes to the joint venture agreement. On completion of the total project, AWACs ownership of Jamalco
would further increase to approximately 77 per cent. The Government of Jamaica would retain ownership of the remaining 23 per cent.

Brazil

Abalco

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

The refinery has a nominal production capacity of 1.4 million tonnes of smelter grade alumina per annum. Approximately half of the
output is consumed at an adjacent smelter, with the remainder exported to third party customers. The major source of energy for the refinery is low sulphur steaming coal purchased from Colombia and Venezuela.

The consortium has long term bauxite purchase contracts with Mineracao Rio Do Norte S.A. (MRN) which has mines located at Trombetas within the State of
Para in northern Brazil. Abalco holds a 9.6% interest in MRN after incorporating Reynolds Metals Companys 5% interest in MRN into AWAC in December 2002. 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 17.4 million tonnes of bauxite each year. Bauxite is transported
approximately 1,400 kilometers by ship to the refinery.

A maritime terminal owned by the consortium and equipped with an alumina ship
loader and bulk materials ship unloader is situated adjacent to the refinery. These facilities are used to ship both bauxite and steaming coal into the refinery and alumina out.

Construction of a 2.1 million mtpy expansion of the Alumar alumina refinery in Brazil by the consortium partners (AWAC, Alcoa Aluminio S.A., BHP
Billiton and Alcan) commenced in 2006. Total refinery capacity will increase to 3.5 million mtpy on completion of the expansion planned for the second half of 2008. AWAC has a 54 per cent interest in the expansion, (1.08 million mtpy of
additional capacity).

Juruti

A new
bauxite mine is being developed in Brazil at Juruti, a high-quality bauxite deposit. A 100 per cent AWAC development, the Juruti mine will initially produce 2.6 million tonnes of bauxite per year to supply AWACs share of the expanded
Alumar facility. The initial 2.6 million mtpy project includes infrastructure that supports further mine expansions.

##### Table of Contents

2006 FORM 20-F

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The estimated capital costs of AWACs current
investments in Brazil have increased, principally due to the appreciation of the Brazilian currency and increased construction costs. The contracting market for major projects in Brazil is seeing substantial increases for project engineering fees,
construction equipment and labour costs. AWACs share of the Alumar refinery expansion and the Juruti bauxite mine was estimated in February 2007 to be approximately US$1.7 billion. The Brazilian currency has appreciated further since February
2007 which increases the capital costs in US$.

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 US$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 1.3 million tonnes,
having completed a 0.2 million tonne expansion at a cost of US$22.2 million in March 2001. San Ciprian employs a high temperature and pressure technology. Bauxite for the refinery is shipped from the Boké mine in Guinea. Steam for the
refinery is generated by the plants own oil fired boiler, with electrical power coming from the national grid.

Approximately 70% of
alumina produced at the San Ciprian refinery is metallurgical grade, which is sold primarily to Alcoas smelters in Spain. The balance of production is non-metallurgical grade alumina that is largely sold as commodity hydrate alumina to
chemical manufacturers. A small portion of the non-metallurgical 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.

Vietnam

AWAC signed a memorandum of understanding (MOU) with Vietnam National CoalMinerals Group (Vinacomin) in March 2006 to explore the feasibility of
creating a joint venture to develop a bauxite mine and alumina refinery in the Dak Nong Province of Vietnam.

The MOU calls for creation of
a joint venture to explore the feasibility of construction and operation of an alumina refinery located in the Gia Nghia bauxite deposit area in Dak Nong Province, with first stage capacity between 1.0 and 1.5 mpty, and with expansion opportunities
thereafter for later expansion.

ii) Shipping

Alcoa
Steamship Inc.

AWAC owns and operates a shipping operation 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 seven combination carriers. AWAC operates two large carriers between Australia and the United States carrying alumina to smelters on the west
coast of the United States and backfilling with raw materials such as petroleum coke and caustic soda for the Australian operations. AWAC operates three smaller vessels in the Caribbean carrying alumina from Suriname and Jamaica to New Orleans, on
the south coast of the United States or Baltimore on the north coast of the United States. These ships are also back filled with raw materials for the Suriname and Jamaican operations. AWAC also charters carriers for the transport of bauxite,
alumina and aluminium (for both AWAC and

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Alcoa) between its various global operations. AWAC also operates two
30,000 tonne 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, although in recent times there has been
significant industry rationalisation through the mergers of Alcoa/Inespal, Alcoa/Reynolds Metal Company, Alcan/Algroup, Alcan/Pechiney, and RUSAL/SUAL/Glencore merging their respective aluminium and alumina assets. The majority of products are sold
in the form of smelter grade alumina with about 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. Pricing
mechanisms have changed over time from primarily fixed amounts and terms to where a substantial portion of present day contracts are related wholly or in part to the price of aluminium traded on the LME.

Markets

AWACs largest customer for its alumina
production is Alcoas primary smelting group which in 2006 accounted for approximately 41% of AWAC alumina production. Remaining sales are usually under long term contracts which are referenced to the LME aluminium price. A small percentage of
production has occasionally been sold into the spot alumina market. No spot sales were made during 2006.

A majority of world production of
alumina is sold under long-term contracts which typically have alumina prices based on a percentage of the aluminium metal price as quoted on the LME. The spot market for alumina is limited, with prices tending to be volatile.

The price paid for the AWAC production by Alcoa smelters (excluding the Alumax smelters acquired by Alcoa in 1998) 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.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------

Alcoa, AWACs largest customer, entered into a new five-year alumina supply contract in 2006. Sales of alumina from
AWAC to Alcoa (other than certain contracts for supply of product to entities which have, during the term of those contracts, been acquired by Alcoa), are priced at the average sales prices under third party (non-Alcoa) contracts.

Alumina produced in Australia by AWAC is shipped to its primary aluminium smelters at Point Henry and Portland in Victoria, or to overseas customers,
principally in South Africa, the Middle East, South East Asia, Russia, China, South America and North America.

Employees

At the end of 2006, AWAC had approximately 7,057 employees in its locations compared with approximately 7,219 in 2005 and 7,019 in 2004. The number of
employees was:



|                  |  |       |  |       |  |

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Regulatory and Environment

The possibility exists that new legislation or regulations may be adopted that may materially adversely affect AWACs mining 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 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 surface
and groundwater quality and availability. Numerous governmental permits and approvals and leases are required for AWACs mining operations. 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 curtailment of operations. This relates particularly to environmental regulations.

At present, Australia does not have in place regulatory requirements to reduce greenhouse gas emissions. However, it is possible Australia will ratify the Kyoto Protocol, which would require Australia to limit greenhouse gas emissions to 8%
over 1990 levels by 2008-2012. Even if the Kyoto Protocol is not ratified, the Australian Government may still introduce regulations to reduce greenhouse gas emissions to pursue achievement of the Kyoto Protocol targets.

In December 2006, the Prime Minister of Australia announced the establishment of a joint government-business Prime Ministerial Task Group on emissions
trading to advise on the nature and design of a workable global emissions trading system in which Australia could participate. The Task Force has reported on additional steps that may be taken, in Australia, consistent with the goal of establishing
such a system. Various Australian state governments have separately stated intentions to introduce emissions trading systems.

At present,
it is not possible to predict the impact that future government regulation may have on Alumina Limited. It is possible, however, that it may increase AWACs capital expenditure and production costs, or may impact on methods of production,
depending on the nature of the regulatory requirements introduced. Alumina Limited cannot assess the nature, magnitude or timing of such costs, including whether these costs would have a material impact on the financial performance of AWAC and
consequently, Alumina.

Since 1994, Alcoa has supported one of the largest and most comprehensive occupational health studies carried out
in Australia. Called Healthwise the study is being conducted by researchers at Monash University and the University of Western Australia.

The study is designed to assess whether there are any relationships between certain health outcomes and working at Alcoa in Australia. It consists of three separate studies:



| |  |  | A cross-sectional respiratory health study of existing employees in 1995/1996, with results reported in 1996,
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | A long-term cancer incidence and mortality study among current and former employees, and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | A respiratory health study of new employees since 1995.
| | - |  | -------------------------------------------------------

The Cancer and Mortality Study compares cancer rates and causes of death among current and former Alcoa employees against the general population by matching employee information with national cancer and death
registries. As well as cancer incidence, it examines the four major causes of death: circulatory disease, respiratory disease, cancer and injury/trauma.

##### Table of Contents

2006 FORM 20-F

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A first search of the national cancer and death
registries until the end of 1996 was reported in 2002, and a second analysis of data to the end of 2002 was completed and reported in 2004, the findings included:



| |  |  | There was a lower overall risk of death in Alcoa employees compared to the general population.
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | Mortality rates for the four major categories of death (circulatory disease, respiratory disease, cancer and injury/trauma) were all lower in Alcoa employees than
in the general population.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The total cancer incidence rate in Alcoa employees was lower than the general population.
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | When individual types of cancers were assessed separately in the refining and smelting operations, most types of cancer occurred only as often as would have been
expected based on general population rates.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For some types of cancer, there were slightly more cases than would have
been expected. Further analyses found that for these types of cancer the risks did not increase with duration of employment. As the study is still at a relatively early stage and exposure data have not yet been examined, it is neither appropriate
nor possible to link any cancer type with a specific work area or exposure.

The next steps in the study are to examine workplace exposures
and also the role of smoking. A third round of national cancer and death registry matching is scheduled to take place in 2008, by which time enough data should have been accumulated to enable further analyses.

In 2005 analysis of the cancer incidence data was conducted for Kwinana refinery, including analysis for specific work locations. This found Kwinana
employees had no more cancers than would be expected in the general population. This was true across the total refinery and in three work locations alleged by a small group of community activists to be areas of concern.

Recruitment of new employees into the new starters respiratory health study, which began in 1995,
was completed in 2004. Analysis began in 2005 on the respiratory test data collected annually on these employees since 1995. This includes quantitative exposure data analyses to see if there are associations between any respiratory function changes
and exposures to specific substances. Analysis of the data for the Victorian Operations was completed and reported in 2006. The results showed associations between smelter exposures and a range of respiratory health measures (symptoms, lung function
and bronchial hyper-responsiveness) consistent with occupational asthma, occurring in some smelter employees. To provide context for the issue, there was an average of three new cases of occupational asthma diagnosed each year from 1995  2003
(the study period) by Alcoas own medical centres within Victorian Operations 1,800 employees. A range of control measures have been implemented in recent years to further reduce the risk of occupational asthma. The latest initiative is a
reduction in the Alcoa Occupational Exposure Limit for fluoride to 0.5mg/m3, well below the current Australian
Workplace Exposure Standard of 2.5mg/m3.

Analysis of the new starters study data for the Western Australian Operations is nearing completion with reporting of the results expected in 2007.

C. Organisational Structure

The
Alumina Group consists of the parent company, Alumina Limited and its subsidiaries. Alumina is incorporated and listed in Australia. Aluminas sole businesses which are operated through AWAC include bauxite mining, alumina refining
and aluminium smelting operated through the AWAC joint venture with Alcoa Inc. (Alcoa). While not itself a legal entity, AWAC is the reference term given to an unincorporated joint venture commenced on January 1, 1995 by Alumina and
Alcoa in combining their respective bauxite, alumina and alumina-based chemicals businesses and interests. The assets of the joint venture are held 40% by the Alumina Group and 60% by Alcoa, with the Alumina Groups interests held through
Alumina International Holdings Pty Ltd and Alcoa of Australia Ltd as described below.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

ITEM 4A. UNRESOLVED STAFF COMMENTS

We are currently in discussions with the SEC staff with respect to
several comments we received regarding our annual report on Form 20-F for the year ended December 31, 2005.

Our financial statements are
prepared in accordance with the Australian Equivalents to International Financial Reporting Standards (A-IFRS), which differ in certain respects from generally accepted accounting principles adopted within the United States of America (US
GAAP). These differences are described in Note 32 Reconciliation to US GAAP. The preparation of financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in
the process of applying Aluminas accounting policies. These estimates and judgements may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the
reported amounts of revenues and expenses during the reported period. Actual results could differ from these estimates.

As a result of
differences between US GAAP and A-IFRS, AWAC has recorded certain constructive asset retirement obligations in its financial statements under A-IFRS but not under US GAAP. The staff has inquired as to whether those constructive obligations should be
recognized under FAS 5, Accounting for Contingencies. AWAC believes that such non-legal constructive obligations recorded under AASB 137, Provisions, Contingent Liabilities and Contingent Assets do not give rise to an
obligation under FAS 5 as the obligation is not considered probable under FAS 5. Probable under FAS 5 has a higher threshold than probable under AASB 137.

On a related matter, the staff has also inquired as to AWACs method of estimating the settlement dates which are used to determine asset retirement
obligations related to the dismantlement, removal and restoration of AWACs smelters and refineries. We believe that AWACs estimates regarding the likely remaining life of those assets are in accordance with AASB 137, which requires the
use of the best estimate of the expenditure required to settle the present obligation at the reporting date. The settlement date of 40 years used as this date coincides with the expiration of the current bauxite mining licenses in
Australia. However, such licenses could be renewed for an additional period of time; alternatively, other sources of bauxite could be used to supply the refineries and smelters. Accordingly, while 40 years represented the earliest possible
settlement date, the ultimate settlement date may in fact be many years later. AWAC management currently has no information that would permit it to reasonably estimate a possible settlement date later than 40 years for purposes of determining a
range as described in paragraph 39 of AASB 137.

The staff also made several comments regarding AWACs practice of not designating
bauxite resources as reserves. The staffs questions focus on how AWAC calculates the expense for depletion of mine development costs as bauxite is extracted and how the lack of ore reserve designation affects the analysis for impairment of
mining assets. The carrying values of AWACs mining assets are assessed against their remaining useful life, and where the carrying values are not expected to be recovered from future cash flows from the use of the assets, an impairment is
recognized.

We received staff comments seeking disclosure of certain technical information, including bauxite specifications, AWACs
methods of determining economic or commercial mineralization, studies with respect to the Juruti mine, and detailed descriptions of certain properties including maps in accordance with the SECs Industry Guide 7(b). The staff also requested
disclosure of longer-term aluminum and/or alumina price assumptions used to assess project economics for bauxite and/or alumina projects. AWAC considers its long term aluminium and alumina price assumptions to be highly commercially sensitive and
therefore has not made this information available due to confidentiality.

Discussions regarding the 2005 Form 20-F are ongoing and may
result in modifications to that document or to this Form 20-F. We will continue to work with the SEC to reach resolution of any outstanding issues.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A. Operating Results

The following discussion should be read in conjunction with the Consolidated Financial Statements, including the notes thereto, which are included in
this annual report. Those Consolidated Financial Statements have been prepared in accordance with the A-IFRS, which differs in certain respects from US GAAP. A discussion of the principal differences between A-IFRS and USGAAP as they relate to
Alumina and a reconciliation of net income, comprehensive income, certain balance sheet items, shareholders equity and cash flows to US GAAP is provided in Note 32 to the Consolidated Financial Statements. Unless noted otherwise, amounts and
disclosures of accounting matters made in this section are determined in accordance with A-IFRS. The critical accounting policies adopted by Alumina are described below.

Critical Accounting Policies

Alumina

The critical accounting policy relating to the continuing operations of Alumina is outlined below. This policy is 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 A-IFRS compliant values. Aluminas significant accounting policies are described in Note 1 to its consolidated financial statements.

Equity accounting Investments in associates are accounted for in the consolidated financial statements using the equity method. Under this
method, the consolidated entitys share of the post-acquisition profits or losses of associates is recognized in the consolidated statement of financial performance, and its share of post-acquisition movements in reserves is recognized in
consolidated reserves.

This accounting treatment is in line with US GAAP. Adjustments are made for GAAP differences which exist in the
underlying profits or losses of the associates prior to the recognition in Aluminas consolidated financial statements.

AWAC

AWACs significant accounting policies are summarized on pages 6 to 11 in the AWAC 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.

AWACs critical accounting policies 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 A-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.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Inventory valuation Inventories are
carried at the lower of cost or market, with cost for a substantial 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.
This method is not allowed under A-IFRS. Alumina adopts the first in, first out (FIFO) valuation methodology in the A-IFRS and USGAAP financial statements.

Foreign currency The local currency is the functional currency for AWACs significant operations outside the U.S., except in Brazil, Jamaica and Suriname, which use the U.S. dollar. 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. Expenditure 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 elements of costs such as site investigations, consultant fees, feasibility studies, outside contractor
expenses 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 periodically 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 and intangibles with indefinite useful lives are not amortized. Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Goodwill and indefinite-lived
intangibles are tested annually for impairment and whenever events or circumstances arise, such as a significant adverse change in business climate or the decision to sell a business, that would make it more likely than not that an impairment may
have occurred. If the carrying value of an indefinite-lived intangible assets exceeds its fair values, an impairment loss is recognized. The evaluation of goodwill impairment involves comparing the current fair value of the reporting unit to the
recorded value, including goodwill. AWAC uses a discounted cash flow model (DCF model) to determine the current fair value of the reporting unit. 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 volume and prices, costs to produce, and working capital changes. Management considers historical experience and all available information at the time the fair
values of its reporting units are estimated. However, actual fair values that could be realized in an actual transaction may differ from those used to evaluate impairment of goodwill. If the DCF model produces a fair value less than the carrying
amount of the reporting unit, an impairment loss is measured by comparing the implied fair value of goodwill to the carrying amount of the goodwill.

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 would also recognize an ARO for any
significant lease restoration obligation if required by a lease agreement. The fair value 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.

Mine Development Costs  Costs incurred during the exploration/evaluation phases are expensed. This phase ends when it has been determined that the mineral deposit can be mined and processed economically.
Development phase costs are capitalized and include costs to construct the mine, including overburden removal, roads, and land improvements. Costs incurred during the production phase are recognized in cost of products sold and include all costs to
extract the minerals, including post-production overburden removal and amortization of any capitalized development costs.

Mine development
costs, classified on the combined balance sheet as other non-current assets and deferred charges, are generally deferred and amortized over the period during which the resources are extracted on a units of production basis. Applicable mine
development costs are charged to expense in the year any program is abandoned.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

General Factors

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

Alumina Limiteds debt is incurred through a US$700 million multi-currency
one, three and five year debt facility entered into on July 19, 2006. The amount of interest charged will impact the profitability of Alumina. The interest amount incurred will depend on the amount of debt carried, interest rates and the impact
of A$/US$ exchange rate movements.

Alumina Limiteds 40% share of AWACs continuing operations during the three year period to
December 31, 2006 was characterized by a focus upon:



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



| |  |  | expansion of existing AWAC operations through brownfield expansions and increasing capacity through operational improvements gained by de-bottlenecking operations
and improving efficiencies; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | seeking to increase production where possible to benefit from higher alumina and aluminium prices.
| | - |  | --------------------------------------------------------------------------------------------------

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. 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 means that the sales revenues (and in
the absence of mitigating factors, profit) generated by sales of AWAC products, can vary considerably from period to period, even where production levels and costs remain constant.

Fluctuations in the A$/US$ Exchange Rate

The world commodity prices for the products AWAC sells are denominated in, or linked to, US$. By contrast, a significant portion of AWACs costs are denominated in A$ and Aluminas accounts are prepared 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. Appreciation of the US$ relative to the A$ increases the value of unhedged sales revenues in A$ as compared to costs and has a
positive impact on profit. A depreciation in the US$ as compared to the A$ decreases the value of unhedged sales revenue in A$ as compared to A$ costs and exerts negative pressure on profit. Alcoa of Australia 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 have an effect on the financial results of Alumina.

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 its or Alumina Limiteds control that can delay deliveries or increase costs for varying lengths
of time.

The cost of AWACs alumina production has increased substantially in recent years, as world demand for commodities has
increased prices of raw materials, freight, energy and labour.

AWAC was protected, to some degree, from higher energy prices in 2006
through energy price hedge contracts entered into during 2005 over a portion of 2006 consumption. 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.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

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.

Regulatory Environment

The costs,
liabilities and requirements associated with the regulations may be costly and time-consuming and may delay commencement or continuation of exploration, expansion or production operations. Of particular importance in Australia is the impact of
environmental regulations and carbon tax/greenhouse gas regulations. The possibility exists that new legislation or regulations may be adopted that may materially adversely affect AWACs operations or cost structure.

The electricity supply to AWACs smelters is primarily under 30-year contracts expiring in 2014 and 2016. The cost of electricity is the largest
individual cost in the production of aluminium. The level of electricity tariffs available after the expiry of these contracts is material to the level of smelter production costs and profitability.

Political Risk

AWAC operates in a
number of countries, some of which have a higher political risk than Australia. 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 of existing operations.

Alumina Limiteds Cash Flows

Alumina Limiteds cash flows are generated primarily from
distributions made by AWAC, by way of dividend 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 partners entered 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. The funding agreement is expected to largely eliminate the risk
identified above, during the five-year term of the funding agreement, of Alumina Limited being constrained in its ability to pay franked dividends to its shareholders.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

2006 Performance Compared to 2005

Overview  Alumina Limited

Aluminas consolidated net profit after tax from continuing operations was A$511.1 million for the year ended December 31, 2006 compared with A$315.6 million for the year ended December 31, 2005. This increase in 2006
compared to 2005 was due to the following:

Share of net profits of associates using the equity method

Share of net profit of associates increased by A$209.5 million to A$546.6 million. Higher US$ sales revenue driven by higher realized prices and alumina
sales was partially offset by higher maintenance costs, increased prices for energy and raw materials including bauxite, and additional caustic soda usage.

General and administrative expenses

General and administrative expenses increased by A$0.5 million
to A$10.7 million. The key items were additional costs incurred during 2006 relating to compliance with the Sarbanes-Oxley Act and legal and tax services associated with the new AWAC funding agreement.

Borrowing Costs

Borrowing costs
increased by A$9.8 million to A$25.1 million due to higher average debt levels and higher average interest rates in 2006.

Income tax
expense

In 2006 Alumina disclosed an income tax expense of A$1.1 million compared to A$nil in the prior year. The key points to note
are:



| |  |  | Taxable income from foreign subsidiary of A$4.0 million;
| | - |  | --------------------------------------------------------



| |  |  | A$34.4 million of expenses which were either non-deductible or against which no income was earned to claim a deduction in 2006 compared to A$21.5 million in 2005.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

Aluminas net cash inflow from operating activities from continuing operations for 2006 was A$496.9 million,
compared to A$72 million in 2005. Higher dividends from associates offset by lower interest revenue from third parties and higher borrowing costs were the main factors driving higher cash from operating activities.

During 2005 Alcoa of Australia declared a special fully franked dividend of A$800 million (Aluminas share A$320 million) all of which was
immediately subscribed to Alcoa of Australia for the purchase of new shares.

Aluminas cash outflow relating to investing activities
from continuing operations was A$259.2 million, compared to A$8.2 million in 2005. This increase in cash outflows from investing activities in 2006 was due to the equity contributions made by Alumina to fund AWAC expansion projects in Brazil and
Jamaica.

Aluminas net cash outflow from financing activities for continuing operations decreased to A$84.2 million, compared to
A$168.4 million in 2005. Key changes were:



| |  |  | drawdowns of US$293 million during the year, offset by debt repayments of US$180 million, compared to drawdowns of US$40 million in 2005.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | proceeds from the issue of shares decreasing to A$10.1 million from A$11.6 million in 2005. The shares were issued in connection with the WMC employee option plan
discussed below in Section 6.E.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Aluminas net assets increased in 2006 by A$224.4
million to A$1,754.6 million. The key points to note are:



| |  |  | Investment in associates increased by A$191.3 million to A$2,186.2 million. The increase was attributable to additional funding capitalization in AWAC entities
amounting to A$259.2 million, a shortfall of dividends received over equity share in profits of A$25.5 million, an offset by the impact of the higher Australian dollar amounting to A$40.6 million and a decrease in AWACs cash flow hedge reserve
of A$52.8 million.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash increased by A$153.8 million to A$169.0 million, for the reasons noted above in the discussion on Aluminas cashflow from operating, investing and
financing activities.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest-bearing liabilities increased by A$109.4 million to A$588.1 million. During 2006 Alumina borrowed an additional US$293 million and repaid debt of US$180
million and the stronger Australian dollar at December 31, 2006 decreased the Companys debt by $A29 million.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Payables increased by A$9.6 million to A$12.7 million. The increase was a result of additional interest payable accruals.
| | - |  | -------------------------------------------------------------------------------------------------------------------------

Aluminas equity increased by A$224.4 million to A$1,754.6 million. The key items include:



| |  |  | A$511.1 million of net profits for 2006;
| | - |  | ----------------------------------------



| |  |  | former employees of WMC Resources exercised 1,971,100 options (increase in equity by A$10.1 million);
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | reduction to equity from a A$52.8 million change in the fair value of cash flow hedges of associates taken to equity;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | reduction to equity from payment of 20.0 cents per share of dividends (A$233.2 million); and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | A$11.3 million net exchange loss recognized in equity.

AWACs 2006 sales revenue of US$5,683.1 million (including sales to parties related to AWAC
of US$2,079.1 million) was 26.3% higher than 2005 sales revenue of US$4,499.8 million (including sales to related parties of US$1,670.2 million). The increase in sales revenue in 2006 was principally due to a stronger aluminium market (with an
average LME aluminium price in 2006 of US117 cents per pound versus 2005 average of US86 cents per pound) and increased alumina sales. Increased global demand for alumina and aluminium was largely attributable to growth in consumption in China,
which rose more than 19% year-on-year. Alumina production was a new record at 14.3 million tonnes (2005: 13.7 million tonnes). Most of the production increase came from the Pinjarra refinery following commissioning of the 657,000 mtpy
capacity upgrade in the second quarter of 2006. Increased production

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

levels at the Wagerup, Kwinana and Suralco refineries, and capacity
creep at other AWAC refineries, accounted for the remainder of the production increase. The annualized production level at the Point Comfort refinery was reduced in November 2006 from 2.3 million mtpy to 1.9 million mtpy by taking down one
of six digesters as part of the optimization of AWAC refinery production.

Aluminium margins increased and 2006 production was 377,351
tonnes compared to 377,259 tonnes in 2005 with seven of AWACs refineries achieving record annual production. This production increase was achieved notwithstanding a power outage at the Portland smelter in November 2005 which affected potline
capacity until the third quarter of 2006. The Point Henry smelter achieved record annual production. The following table shows AWACs production information for 2005 and 2006.

|Aluminium Production (000 tonnes)  |  | 377  |  | 377 
|LME Aluminium Price (US$/lb)        |  | 0.86 |  | 1.17

AWACs net income of US$1,122.1 million in 2006 represented an increase of 74% compared to
2005. The improvement in 2006 was due largely to the price factors discussed above and increased production of alumina. The total costs of sales for 2006 was 13% higher than 2005. AWACs average cost of alumina production rose by US$18 per
tonne due to price increases in energy and raw materials including bauxite, and additional caustic soda usage. Costs were also impacted by maintenance and contractor cost increases.

The average aluminium price as quoted on the London Metals Exchange (LME) increased 36 per cent during 2006. Higher LME aluminium prices reflect
strong world-wide demand and low stock levels, with Chinese aluminium consumption continuing to be a driver.

Aluminium consumption in
China rose by more than 19 per cent year-on-year, with strong demand from construction, transport infrastructure and industrial production. The 7 per cent growth in 2006 in worldwide demand for aluminium continued the trend of strong
demand since 2003.

Global demand for aluminium and alumina is forecast to continue to grow strongly through 2007, with Chinese domestic
demand for aluminium projected to grow by at least 14 per cent, and Western growth at approximately 3 per cent.

Alumina markets
moved from being in deficit in 2005 and through the first half of 2006 to finish the year with surplus production capacity. China reduced its dependence on imports by adding approximately 5 million tonnes of alumina production capacity in 2006;
this was faster capacity growth than expected.

Long-term alumina contract prices increased in 2006, driven by their links to the aluminium
price which rose significantly for the year. The majority of AWAC customer sales are long-term, with only a small percentage sold in the spot market. AWACs strategy is to continue to negotiate such long-term contracts to support its investment
in future capacity expansion.

Alcoa, AWACs largest customer, entered into a new five-year alumina supply contract in 2006. Sales of
alumina from AWAC to Alcoa (other than certain contracts for supply of product to entities which have, during the term of those contracts, been acquired by Alcoa), are priced at the average of sales prices under third party (non-Alcoa) contracts.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

AWACs profit will continue to be most sensitive
to changes in the aluminium price and the A$/US$ exchange rate.

AWACs net cash inflow from operating activities increased to
US$1,280.9 million, compared to US$802.4 million in 2005. The 59.6% increase in 2006 was primarily due to higher aluminium and alumina realised prices.

Net cash outflow from financing operations increased to US$470.4 million, compared to US$165.2 million in 2005. Key changes were:



| |  |  | an increase in level of dividends paid to partners of US$807.8 million;
| | - |  | -----------------------------------------------------------------------



| |  |  | an increase in partners contributions, totalling of US$500.5 million in 2006, compared to US$21.1 million in 2005, to fund the expansion projects in Brazil

| |  |  | the amount of capital expenditure required by AWAC to develop new projects or maintain or expand existing operations, (refer to Section 4.B for discussions of
the upgrade/expansions of Pinjarra and Suriname refineries, expansion of the Wagerup and Jamalco refineries, development of the Juruti bauxite mine and Alumar refinery, potential investment in a refinery in Guinea).

We expect these factors will continue to influence Aluminas liquidity and capital resources in future years.

In addition, because Alumina 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 would be limited by, the amount of dividends received from its subsidiaries 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 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). Alcoas stated view is that AWAC should use available cash flow to meet its financing needs, such as funds needed for expansion commitments. This method of
funding expansion projects would reduce dividends paid by AWAC during the period of funding and would require loans between AWAC entities. Such loans require the agreement of Alcoa and Alumina. 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 US$1 billion following a decision by a majority vote of the Strategic Council, of which Alcoa Inc. has majority voting power.

In 2006, Alumina and Alcoa entered into new funding arrangements to provide the AWAC partners with additional dividends from Alcoa of Australia for funding AWACs capital projects. The funding arrangements
provide greater certainty to Alcoa and Alumina Limited in dividend flows and franking credits. During 2006, Alumina received fully franked dividends of A$510 million from Alcoa of Australia.

Aluminas existing balance of franking credits and the new funding arrangements between Alumina and Alcoa provide greater confidence in
Aluminas capacity to continue to declare fully franked dividends.

Dividends received from Alcoa of Australia have substantially
funded Aluminas investment in AWACs growth projects and sustaining capital projects. Alumina share of any remaining funding requirements will be met by increased borrowings. As a result, interest costs are expected to rise.

Alumina implemented an off-market buy-back of approximately $A250 million of ordinary shares in April 2007.

During 2005, Alcoa of Australia declared a special fully franked dividend of A$800 million (Aluminas share was A$320 million), all of which was
immediately subscribed to Alcoa of Australia for the purchase of new shares. As a result of this transaction, which was the subject of a prior ruling by the Australian Taxation Office, and the funding agreement signed in 2006, which was also the
subject of prior rulings by the Australian Taxation Office, Alumina is able to declare dividends, at least at the current levels, on a fully franked basis, for the foreseeable future. Alumina directors have advised shareholders that, subject to
business conditions, the Company intends to at least maintain dividends to shareholders of 24 cents per share per annum.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Alumina intends utilizing any dividends received in
the next 3 to 4 years from AWAC entities other than Alcoa of Australia to fund its corporate and financing costs and capital requirements.

Aluminas gross debt at December 31, 2006 was A$588.1 million offset by cash assets of A$169.0 million. Subsequent to year end Alumina paid a final 2006 dividend of A$140.1 million and received a dividend from Alcoa of Australia
of A$200.0 million. AWAC had a cash surplus net of debt at December 31, 2006 of US$63.0 million. AWACs operating cashflow for 2006 was US$1,280.9 million.

Alumina established a new US$700 million multi-currency one, three and five year debt facility in mid-2006. Alumina continues to maintain a A- debt rating with Standard & Poors.

In view of the current AWAC growth projects requiring funding to be contributed by the AWAC partners, and the capital management initiatives being
undertaken by Alumina, the Company will be increasing its debt facilities in the first half of 2007. Additional medium term bank debt of US$175 million has been put in place in the first half of 2007.

Funds generated from continuing operating activities were A$496.9 million for the year ended December 31, 2006, compared with A$72.0 million in
2005. This increase was a result of higher dividends from associates as well as lower supplier payments partially offset by higher borrowing costs.

Working capital was negative A$223.6 million at December 31, 2006, compared to negative working capital of A$464.8 million at December 31, 2005. The negative working capital is primarily due to A$380.2 million of short-term
borrowings. Aluminas net debt decreased during the year from A$463.5 million to $A419.1 million. The Companys working capital, in our opinion, is sufficient for the Companys present requirements.

Gross debt drawn down under the Companys new US$700 million multi-currency one, three and five year debt facility was A$588.1 million at December
31, 2006 and A$478.7 million at December 31, 2005, under Aluminas previous facility, as a result of drawing down a further US$293 million (A$392.3 million) offset by repayment of borrowings of US$180 million (A$252.4 million). The increase in
debt at year end reflects Aluminas equity contributions to fund AWACs expansion projects in Brazil and Jamaica.

The maturity
of debt is outlined in Note 15 in the Consolidated Financial Statements. Aluminas current debt facilities are short and medium term US dollar borrowings, reflecting the modest debt level and low short term interest rates. The key funding
principles inherent in Alumina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 examined to achieve a balance sheet hedge and reduce foreign exchange
translation exposures; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | interest costs should be minimised if Alumina does not have assessable income for tax purposes.
| | - |  | -----------------------------------------------------------------------------------------------

Cash and current investments was A$169.0 million at December 31, 2006 compared with A$15.2 million at December 31, 2005.

Available sources of liquidity were represented by unused bank facilities at December 31, 2006 of US$236.0 million (A$299.1 million), as
compared to A$221.3 million at December 31, 2005. The increase was due in part to the new US$700 million multi currency one, three and five year loan facility replacing the A$700 million 364 day facility.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Capital expenditure was A$259.2 million for the year
ended December 31, 2006, and A$8.2 million for the year ended December 31, 2005. The expenditures were attributable to equity contributions to fund AWACs expansion projects in Brazil and Jamaica during 2006.

The obligations of Finance (USA) under the US Bonds were guaranteed by Alumina. In connection with the demerger, Finance USA tendered to repurchase the
US Bonds remaining outstanding. The aggregate amount of outstanding bonds not repurchased was comprised as follows of:



| |  |  | US Bonds due November 15 2013  US$3,658,000
| | - |  | --------------------------------------------



| |  |  | US Bonds due December 1, 2026  US$115,000
| | - |  | ------------------------------------------

These outstanding US Bonds continue to be guaranteed by Alumina. The duration of the guarantee is unlimited, and continues as long as amounts are outstanding under the US Bonds.

Under the demerger deed, Alumina and WMC Resources indemnify each other in respect of certain liabilities. Alumina would be entitled to reimbursement
from WMC Resources for amounts paid by Alumina under the guarantee in respect of the US Bonds.

Pursuant to a Power Purchase Agreement
dated November 27, 1998 between WMC Resources, WMC Limited (as it then was) and Southern Cross Energy, Alumina has undertaken to provide Southern Cross Energy with a guarantee or letter of credit for WMCRs payment for power in the event
that WMCRs gross assets fall below A$250 million in any year.

During 2005, WMC Resources was acquired by BHP Billiton.

New Accounting Pronouncements

Refer to Note 1(W)
of the audited financial statements for new accounting pronouncements.

Australian Accounting Standards Board

The Australian Accounting Standards Board (AASB) has adopted International Financial Reporting Standards (IFRS) for application to reporting
periods beginning on or after January 1, 2005. The AASB has issued Australian equivalents to IFRS (A-IFRS), and the Urgent Issues Group has issued interpretations corresponding to IASB interpretations originated by the International Financial
Reporting Interpretations Committee or the former Standing Interpretations Committee. The adoption of A-IFRS was reflected in the consolidated entitys financial statements for the half-year ending June 30, 2005 and the years ended
December 31, 2006 and December 31, 2005.

Entities complying with A-IFRS for the first time were required to restate their
comparative financial statements to amounts reflecting the application of A-IFRS to that comparative period. Most adjustments required on transition to A-IFRS were made retrospectively against opening retained earnings as at January 1, 2004.

Financial Accounting Standards Board

The Financial Accounting Standards Board has issued certain Statements of Financial Accounting Standards which are not effective with respect to AWAC and therefore Alumina for the fiscal years presented in the consolidated financial
statements. The impact or potential impact for both AWAC and Alumina is discussed below.

In September 2006, the FASB issued SFAS No. 157, Fair Value
Measurements, (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted principles, and expands disclosures about fair value measurements. The provisions of this standard apply to
other accounting pronouncements that require or permit fair value measurements. SFAS 157 becomes effective for AWAC on January 1, 2008. Upon adoption, the provisions of SFAS 157 are to be applied prospectively with limited exceptions. The
adoption of SFAS 157 is not expected to have a material impact on Alumina Limiteds financial statements.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In July 2006, the FASB issued FASB Interpretation No. 48,
Accounting for Uncertainty in Income Taxes  an Interpretation of FASB Statement No. 109, (FIN 48). Fin 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial
statements uncertain tax positions that it has taken or expects to take on a tax return. On January 17, 2007, the FASB affirmed its previous decision to make FIN 48 effective for fiscal years beginning after December 15, 2006. Accordingly,
FIN 48 is effective for AWAC on January 1, 2007. The adoption of FIN 48 will not have a material impact on Alumina Limiteds financial statements.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Prior to the demerger, the establishment of the WMC
Employee Share Scheme was approved by shareholders at the Annual General Meeting held on December 12, 1987. Under the Scheme a number of share plans operated. Fully paid shares, partly paid shares and share options were granted to employees
since the establishment of the Scheme. These options remained exercisable until November, 30 2006. There is no ongoing option plan available to Alumina Limited directors or employees.

In February 2003, a share plan for Alumina employees was introduced. The plan provides rewards for employees based on Aluminas performance against
two peer indices. Actual rewards depend upon the performance of Alumina exceeding the performance of a percentage of companies in an index on a total shareholder return basis. All rewards for employees through this plan are directed to purchasing
Alumina shares, with executive officers required to hold shares equivalent in value to 0.5 times their salary. These Alumina shares may only be released to executives once the multiple is exceeded and then only those shares over the multiple.

From December 2002, short term incentives are payable to management according to key performance indicators applicable to the individual
and Alumina.

Prior to Aluminas demerger, all full time Australian based employees and expatriate employees of WMC Limited (including
executive directors and officers) and its subsidiaries were members of the WMC Superannuation Plan (formerly WMC Superannuation Fund).

Aluminas current employees are members of the Alumina Superannuation Plan. This plan is an accumulation plan, which offers a minimum company contribution (subject to certain cashing out options and legislation) of 9 per cent of
basic salary to each members account.

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.

Relevant experience, diverse perspectives
and complementary business skills are sought when appointing new directors. The Board comprises a non-executive chairman, three other non-executive directors and one executive director. A balance between independent business experience 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.

At least 10 Board meetings are held each year. Board visits are regularly conducted to AWAC operational sites to review business performance, review operating processes and meet with management. .

The Directors (other than a Managing Director) are subject to retirement by rotation, one-third retiring each year (or the number nearest to one-third if
the number of Directors is not a multiple of three), and may not continue to hold office without re-election after the third Annual General Meeting following their last election by the shareholders. Eligible retiring directors may offer themselves
for re-election by the shareholders. The Companys Nominations Committee Charter provides that Non Executive Directors shall retire after 9 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 9 year period) unless otherwise requested to continue by the Board. Executive Directors are required to retire at 65 years of age. After elected by the shareholders, 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.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Each Director has the power to appoint any person
approved by a majority of his co-Directors to act as an Alternate Director in his 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 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 either for an unlimited period but not for life, a fixed term not exceeding five years, or a period terminable upon the happening of such specific events as the Directors may stipulate. The Directors may confer upon
any Managing Director such of the powers exercisable under Aluminas Constitution by the Directors as they may elect, without derogating from the exercise of those powers by the Directors. John Marlay is currently the Managing Director and
Chief Executive Officer of Alumina and was appointed to such position for an unspecified period.

Aluminas Constitution provides that
the Directors may elect a Chairman of their meetings and determine the period for which he is to hold office. Where there is an equality of votes on a question voted on at a meeting, the Chairman has a second or casting vote. Donald M Morley is
currently the Non-Executive Chairman of Alumina.

Aluminas most senior employee, the Chief Executive Officer, is selected by the
Board and is subject to semi-annual performance reviews by the non-executive directors. The Chief Executive Officer recommends policy and strategic direction for board approval and is responsible for managing day-to-day business performance.

Specific board committees assist the full Board. Charters set out the roles and terms of reference for the Audit, Compensation and
Nomination Committees. The Audit Committee, consisting of four non-executive directors, meets at least four times a year, assists the Board in fulfilling its responsibilities for the Companys accounts and external reporting by ensuring
that appropriate processes are in place to support the Board in fulfilling its responsibilities for:



| |  |  | reporting of financial information to users of Aluminas financial reports;
| | - |  | ---------------------------------------------------------------------------



| |  |  | Aluminas application of accounting policies;
| | - |  | ---------------------------------------------



| |  |  | Aluminas internal financial control systems;
| | - |  | ---------------------------------------------



| |  |  | the independent auditors qualifications and independence;
| | - |  | ---------------------------------------------------------



| |  |  | the performance of Aluminas independent auditors and internal audit function, and
| | - |  | ----------------------------------------------------------------------------------



| |  |  | agreeing the scope and monitor the progress of Aluminas internal audit plan.
| | - |  | -----------------------------------------------------------------------------

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 four non-executive directors meets at least two times a year. Its role is to establish and review
Alumina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, 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:



| |  |  | employee interests are aligned to corporate objectives;
| | - |  | -------------------------------------------------------



| |  |  | the company can attract, develop and retain motivated and talented employees; and
| | - |  | ---------------------------------------------------------------------------------



| |  |  | the integrity of the companys reward programme is maintained.
| | - |  | --------------------------------------------------------------

The Compensation Committee also approves payments to all directors and reviews director remuneration annually based on independent external advice with regard to market practices, relativities and the duties and
accountabilities of directors.

The Nomination Committee consists of four non-executive directors and meets as necessary. Its role is to
assist the Board in fulfilling its responsibilities to shareholders relating to:



| |  |  | identifying the necessary and desirable competencies of board members;
| | - |  | ----------------------------------------------------------------------



- 54 -

| |  |  | assessing the extent to which the competencies are represented on the board;
| | - |  | ----------------------------------------------------------------------------



| |  |  | the selection and appointment process for directors. and
| | - |  | --------------------------------------------------------



| |  |  | conducting performance evaluations of directors who are retiring and seeking re-election.
| | - |  | -----------------------------------------------------------------------------------------

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, 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. During 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.

The New York Stock Exchange (NYSE) Listing Rules, Section 303A, have a broad regime of new 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.09 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. listed 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.

Retirement and termination benefits

Chief Executive Officer

Under Mr Marlays employment contract, which does not have a fixed term, either party may terminate the contract upon giving 12 months 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 plus an amount equivalent to an STI payment at target performance, defined as base remuneration. The base remuneration
amount will be reduced pro rata to the extent the notice period is required to be served.

the Australian Stock Exchange, or if there is a significant change to
his status and/or responsibilities which is detrimental to Mr Marlay, or if Alumina decides the position is no longer required and suitable alternative employment is not offered or Mr Marlay does not accept other employment within Alumina or another
employer) then Mr Marlay is entitled to:



| |  |  | statutory annual leave and long service leave entitlements;
| | - |  | -----------------------------------------------------------



| |  |  | the greater of six months base remuneration or the aggregate of; a notice payment of 12 weeks, a severance payment of 2.5 weeks per completed years of service plus
an additional severance payment of 13 weeks.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mr Marlay is not entitled to the payment outlined above where the reason
for a Significant Change is poor performance or inability to fulfill agreed responsibilities. Mr Marlay is not entitled to retirement benefits other than superannuation entitlements.

In addition to any entitlements conferred on Mr Marlay under his service contract, Mr Marlay is entitled to receive on termination of employment, his
statutory entitlements of accrued annual and long service leave, together with any superannuation benefits. Mr Marlay is not entitled to receive any other additional termination benefits, other than those previously mentioned and any vesting of
shares under the Alumina Employee Share Plan.

Senior Executives

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

If Mr Dean or Mr Foster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, then Mr Dean and Mr Foster are entitled to:



| |  |  | statutory annual leave and long service leave entitlements (with long service leave paid pro rata if there is 3 years or more continuous service);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the greater of six months base remuneration or the aggregate of; a notice payment of 12 weeks, a severance payment of 2.5 weeks per completed years of service plus
an additional severance payment of 13 weeks.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mr Dean and Mr Foster are not entitled to payment outlined above where the
reason for a significant change is poor performance or inability to fulfill agreed responsibilities. Mr Dean and Mr Foster are not entitled to retirement benefits other than superannuation entitlements.

Non-Executive Director Retirement Benefits

Non-executive Directors receive, in addition to their fees, a superannuation guarantee contribution which for 2006 was 9 per cent of their fees, being A$12,412 for the Chairman and A$10,350 for other Non-executive Directors, but
do not receive any other retirement benefits. From January 1, 2006, the Superannuation Guarantee contribution for the Chairman is capped at A$12,412.

D. Employees

At December 31, 2006, Alumina employed 9 people directly. All Alumina 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.(iv) Employees.

E. Share
Ownership

Employees of Alumina, who were formerly employees of WMC, were eligible to participate in and receive options under the WMC
Employee Option Plan. Following the demerger each WMC employee option became an



- 56 -

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Alumina Limited option and entitled the holder to subscribe for one
Alumina Limited share. The exercise price of options held over at the date of the demerger was reduced from the previous WMC exercise price at a factor of 0.537. There is no ongoing option plan available to Alumina directors or employees and
accordingly, no allotments were made to Alumina employees after the demerger.

This option plan expired on November 30, 2006. There
were 1,971,100 options exercised during the year.

WMC Employee Share Scheme (Expired November 30, 2006)

The establishment of the WMC Employee Share Scheme (ESS) was approved by shareholders at the Annual General Meeting held on December 12,
1987. Under the ESS a number of share plans have operated. Fully paid shares, partly paid shares and share options have been granted to employees since establishment of the ESS. All permanent employees (including executive directors) of Alumina
Limited and its subsidiaries who were employed by the company or a subsidiary were eligible to participate in the ESS and were offered options for fully paid shares prior to demerger. Existing options allotted to Alumina employees remain exercisable
until such time as their exercise periods expire. There is no ongoing option plan available to Alumina Limited directors or employees following the demerger. This Scheme expired on November 30, 2006.

Impact of demerger on plans

In conjunction with the
demerger, WMC Limited and WMC Resources Ltd entered into an employee benefits agreement. This agreement covered the treatment of WMC Limited common stock options issued to WMC Limited and WMC Resources employees. According to the agreement, each WMC
Limited option granted to WMC Limited and WMC Resources employees prior to December 4, 2002, that was outstanding under the ESS as of the demerger date, was adjusted. This adjustment resulted in each individual who was a holder of a WMC Limited
option receiving, immediately after the demerger date, an adjusted WMC Limited option and a WMC Resources option. As part of the demerger from WMC Limited, WMC Limited option holders were granted one option for Alumina Limited and one for WMC
Resources Ltd. The aggregate exercise prices of the Alumina Limited option and the WMC Resources Ltd option is equal to the exercise price of the WMC Limited option prior to demerger. The Alumina Limited option and WMC Resources option have the same
lapse date as the WMC Limited option would have had if the demerger had not proceeded  being the earlier of five years after the option was issued and 30 days after the WMC Limited option holder ceases to be employed by WMC Limited Group, WMC
Resources Group or Alumina Group. The exercise price of a WMC Resources Ltd option was determined by reference to the pre-demerger exercise price of the WMC Limited option (which became an Alumina option) in respect of which the WMC Resources Ltd
option was granted and the volume weighted average price of WMC Resources shares and Alumina Limited shares sold on the ASX over the first five days of trading on the ASX commencing on the listing date. The Stock Appreciation Plan was treated in the
same manner as the Share Scheme, as described above.

Partly Paid Share Plan

The major provisions of the partly paid share plans provide that the employee may request that the shares be made fully paid after one year from the date
of allotment. Partly paid shares are exercisable at the lower of the exercise price and the market price at the date of conversion. All partly paid shares were converted to fully paid shares during 2002, prior to the demerger.

The partly paid shares were granted to a select few employees which makes the plan a compensatory plan under US GAAP. This results in a stock
compensation expense to the company when the market price is greater than the exercise price on date of grant. As a result of non-interest bearing notes granted to the employees to purchase the partly paid shares, the shares were considered variable
grants. Variable grants require the shares to be marked to market and compensation expense to be recognized for the difference between the fair value and the exercise price at each balance sheet date.

Stock Appreciation Plan (Expired November 30, 2006)

In various years since approval of the WMC Employee Share Scheme (ESS) in 1987, until the demerger of the company, the
company established Stock Appreciation Plans (SAPs) for the benefit of employees mainly in countries outside Australia. The purpose of the SAPs was to provide such employees, who due to securities law constraints were not eligible to
participate under the Option Plans, with benefits similar to those conferred by the Option Plans. This plan expired on November 30, 2006.

Under the terms of the WMC Stock Appreciation Plan (SAP), employees were invited to apply for the grant by WMC Limited. The employees were not required to pay any amount for the grant, but each WMC Limited SAP has a notional allotment
exercise price, equal to the weighted average sale price of WMC Limiteds (or, post - demerger Alumina Limited) shares on the ASX on the trading day that the invitation to apply for the WMC Limited SAP was made to the employee. Subject to
certain exceptions, the WMC Limited SAP was not able to be redeemed until after a period of 12 months from the date of allotment and lapse on the fifth anniversary of the date of allotment. Upon redemption of a WMC Limited SAP before its expiry
by the holder, the holder is entitled to a payment equal to the difference between the closing share price of WMC Limited (or, post-demerger Alumina Limited) on the ASX on the trading day immediately before redemption, and the notional allotment
price (assuming the former amount is higher). Compensation cost is measured as the amount by which the quoted market value of the shares covered by the grant exceeds the allotment price.

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.

Generally, each offer has a three year performance period, with performance tested at the end of this period to determine the number of performance rights to vest to the employee, if any. 50% of the performance rights
not vested at the three year performance test can be re-tested six months after the end of the three year performance period. The performance testing is carried out by an independent party and is based on the relative Total Shareholder Returns (TSR)
of Alumina Limited, compared to two specific comparator groups.

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 finalized and any performance rights not vested lapse unless the
Directors decide otherwise.

Short-Term Incentive Equity Plan

From January 2007, the Company will operate a short term incentive equity conversion plan (STI Equity Plan) for senior executives and other eligible employees. Under the STI Equity Plan, participants may
elect to apply all or a portion of their short-term incentive to the acquisition of shares (which are purchased on market), with all costs of acquisition being borne by the participant. In addition, to the extent an eligible employee elects to
acquire Company shares under the STI Equity Plan, they will, upon continuing to be employed by the Company for three years from the date of acquiring shares under the STI Equity Plan, receive additional Company shares equal to:



| | i. | 50 per cent of their Company shares acquired (Matching Shares) and
| | -- | --------------------------------------------------------------------



| | ii. | shares equal to the amount of dividends that would have been paid on the Matching Shares if they had been acquired at the same time as the initial shares.

All fully paid shareholders have the same voting rights as any other fully paid shareholder.

There are no arrangements, known to the Company, the operation of which may at a subsequent date result in a change in control of Alumina.

As at December 31, 2006, 505,552 Alumina fully paid Ordinary Shares were registered in the name of 243 residents of the United States
and represented approximately 0.04% of the total number of Alumina fully paid Ordinary Shares issued and outstanding. As at December 31, 2006, 24,959,841 Alumina ADRs were outstanding (representing 99,839,364 Alumina fully paid Ordinary Shares)

B. Related Party Transactions

Loans to directors

No loans were provided in 2005 or 2006, and no balances remain outstanding at 2005 or 2006.

Shareholding transactions of directors

Aluminas directors are also shareholders of the company
and as such, they may purchase or sell Aluminas shares.

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.

Directors who were employees of the WMC
Limited group prior to the demerger were eligible to participate in the WMC Employee Share Scheme, and were issued with options, priced at market value. These transactions were conducted on a commercial basis on terms no more beneficial than those
available to other eligible employees.

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 prior to the enactment of the Racial Discrimination Act 1975 (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 (removed). Although a determination of native title does not invalidate anothers validly granted, 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 Alcoa of Australia Ltd because 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 Alcoa of
Australia Ltds Special Mining Lease MLISA (Western Australia) (the Alcoa Lease) and a portion of the conveyor associated with Alcoas 45% interest in the Portland Smelter (Victoria).

FINANCIAL INFORMATION

(a) Western Australia

Alcoa of Australia Ltds operations fall within the Gnaala Karla Booja native title claim (Federal Court file number WG6274/98), which is yet to be
determined.

However, as a result of the Ward decision, the potential exposure of Alcoa of Australia Ltd 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

Alcoa of Australia Ltds interest in Portland Smelter falls within the Gournditch-Mara native title claim  Federal
Court file number VID6004/98 which is yet to be determined.

However, the Portland Smelter is situated on a validly granted freehold title
which has been excluded by the claimants from this claim. Therefore the claim only affects a small portion of the land on which the Portland Conveyor is situated pursuant to a Conveyor Licence Agreement.

While native title may still exist in the above Western Australian and Victorian claim areas, the Alcoa Lease and the Conveyor Licence Agreement are
valid and Alcoa of Australia Ltds rights will prevail to the extent of any inconsistency. Accordingly, Alcoa of Australia Ltd is entitled to continue its operations without interference from native title claimants.

Other Events

On May 25, 2005, Alcoa Inc.
(Alcoa) was served with a federal grand jury subpoena by the Antitrust Division of U.S. Department of Justice (DOJ). The DOJ is investigating possible criminal violations of the antitrust laws and related matters concerning the aluminum
fluoride industry. Aluminum fluoride is used in the process of smelting aluminum in all of Alcoas smelters worldwide. AWAC produces aluminum fluoride for sale to Alcoa and third parties (at Pt Comfort) Alcoa produces aluminum fluoride for
internal use and third party sales. Alcoa also purchases aluminum fluoride from others and is a net purchaser. Antitrust authorities in Canada and Australia have also made inquiries into Alcoa. Alcoa has cooperated with all three authorities in
their respective investigations and has completed production of requested documents and has filed narrative answers to all questions posed.

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.

AWACs Point Comfort alumina refinery is part
of an area which has been declared a US Environmental Protection Agency superfund site.

There has been publicity in respect of
complaints by some nearby residents of the Wagerup refinery that there is a link between their various health problems and odours and emissions from the refinery. Legal proceedings have been filed by some nearby residents of the Wagerup refinery in
the District Court in Western Australia claiming damages and alleging that emissions from the Wagerup refinery have harmed their health.

As previously reported, in September 1998, Hurricane Georges struck the U.S. Virgin Islands, including the St. Croix Alumina LLC facility on the island of St. Croix. AWAC sold its interest in the St Croix refinery in June 2002. The
wind and rain associated with the hurricane caused material at the location to be blown into neighbouring residential areas. Various clean-up and remediation efforts were undertaken by or on behalf of St. Croix Alumina LLC. A Notice of
Violation was issued by the Division of Environmental Protection of the Department of Planning and Natural Resources of the Virgin Islands Government, and has been contested by the company. A civil suit was commenced in the Territorial Court of
the Virgin Islands by certain residents of St. Croix in February 1999 seeking compensatory and punitive damages and injunctive relief for alleged personal injuries and property damages associated with bauxite or red dust from the St.
Croix Alumina LLC facility. The suit, which has been removed to the District Court of the Virgin Islands, names St. Croix Alumina LLC, Alcoa Inc. and Glencore Ltd. as defendants and in August 2000 was accorded class action treatment. The
class is defined to include persons in various defined neighbourhoods

who suffered damages and/or injuries as a result of exposure during and after Hurricane
Georges to red dust and red mud blown during Hurricane Georges. All of the defendants have denied liability, and discovery and other pretrial proceedings have been underway since 1999. In October 2003, the defendants received
plaintiffs expert reports. These reports claim that the material blown during Hurricane Georges consisted of bauxite and red mud, and contained crystalline silica, chromium and other substances. The reports go on to claim, among
other things, that the population of the six subject neighbourhoods as of the 2000 census (a total of 3,730 people) has been exposed to toxic substances through the fault of the defendants, and hence will be able to show entitlement to lifetime
medical monitoring as well as other compensatory and punitive relief. These opinions have been contested by the defendants expert reports, that state, among other things, that plaintiffs were not exposed to the substances alleged and that
in any event the level of alleged exposure does not justify lifetime medical monitoring. In August 2005, Alcoa and St. Croix Alumina LLC moved to decertify the plaintiff class, and in March 2006, the assigned magistrate judge issued a
recommendation that class certification be maintained for liability issues only, and that the class be decertified after liability issues have been resolved. This recommendation has been adopted by the assigned district judge. Alcoa and St. Croix
Alumina LLC have turned over this matter to their insurance carriers who are providing a defence. Glencore Ltd. is jointly defending the case with Alcoa and St. Croix Alumina LLC and has a pending motion to dismiss.

As previously reported, in May 2005, Alcoa World Alumina LLC and St. Croix Alumina LLC were among the defendants listed in a lawsuit brought by the
Commissioner of the Department of Planning and Natural Resources, Dean Plaskett, in his capacity as Trustee for Natural Resources of the Territory of the United States Virgin Islands in the District Court of the Virgin Islands, Division of St.
Croix. The complaint seeks damages for alleged injuries to natural resources caused by alleged releases from an alumina refinery facility in St. Croix that was owned by St. Croix Alumina LLC from 1995 to 2002. Also listed in the lawsuit are previous
and subsequent owners of the alumina refinery and the owners of an adjacent oil refinery. Claims are brought under CERCLA, U.S. Virgin Islands law, and common law. The plaintiff has not specified in the complaint the amount it seeks in damages. The
defendants have filed motions to dismiss and, in September 2006, filed a motion for an order staying discovery pending resolution of those motions. All of these motions are pending and discovery has not begun.

On December 1, 2006, St. Croix Alumina LLC was sued by the Commissioner of the Department of Planning and Natural Resources (DPNR), U.S. Virgin
Islands, in the Superior Court of the Virgin Islands, Division of St. Croix. The complaint seeks the completion of certain actions regarding the facility in St. Croix, a civil fine and exemplary damages for alleged violations of the Coastal Zone
Management Act and a construction permit issued pursuant to that Act.

On January 2, 2007, St. Croix Alumina LLC, along with
unaffiliated prior and subsequent owners, were sued by the Commissioner of the DPNR, U.S. Virgin Islands, in the Superior Court of the Virgin Islands, Division of St. Croix. This second suit alleges violations by the defendants of certain permits
and environmental statutes said to apply to the facility in St Croix. The complaint seeks the completion of certain actions regarding the facility, a civil fine and exemplary damages for alleged violations of the Coastal Zone Management Act and a
construction permit issued pursuant to that Act.

On January 22, 2007, the City of Point Comfort, Texas filed suit against Alcoa World
Aluminum, LLC (AWA) in the United States District Court for the Southern District of Texas. Served on January 31, 2007, the suit alleges that air emissions from AWAs Point Comfort facility have caused personal injury and property damage
to the city and its residents. The complaint seeks injunctions prohibiting operation and unspecified damages.

The Brazilian
Federal Public Prosecutors office challenged the issue of the installation licence for the Juruti project in September 2005 alleging a lack of jurisdiction of the Executive Department of Sciences, Technology and Environment  SECTAM
(state agency) to conduct the licensing. This proceeding is currently before the Court of Obidos  PA, awaiting revaluation of the initial petition, due to the decision made by the Federal Judge of Santarem.

Other Financial Information

Dividend Policy

Alumina Limited intends, subject to
business conditions, to maintain dividends to Alumina shareholders at current levels through the current period of substantial growth. Dividends are paid twice a year. An interim dividend is paid in September or October and the final dividend is
paid in March or April.

The dividends paid to shareholders are determined by the Board of Directors, based on Aluminas performance
and current business conditions.

During the 12 month period January 1, 2006 to December 31, 2006, Alumina paid cash dividends to
its shareholders of A$0.20 (fully franked) per fully paid ordinary share. This compares to cash dividends provided for the 12 months to December 31, 2005 of A$0.20 (franked to A$0.175) per fully paid ordinary share. For a discussion on the
taxation of the dividends, see Item 10E Additional Information  Taxation.

On February 1, 2007 the Directors
declared a final dividend, paid on March 9, 2007, of 12 cents per share. This was a 20% increase on previous half-yearly dividends, and at the time the Directors advised that, subject to business conditions, they intend to at least maintain
annual dividends at this new level of 24 cents per share.

Financing and Corporate Items

Net financing and corporate expenses for the year ended December 31, 2006 totalled A$34.4 million compared to A$21.5 million for the year ended
December 31, 2005. The principal components were:



|                               |  |                              |   |  |                              |  
|------------------------------ |  | ---------------------------- | - |  | ---------------------------- | -

Net interest charged to profit was A$23.7 million for the year ended December 31, 2006
compared to A$11.3 million for the year ended December 31, 2005, reflecting higher average interest rates and a higher level of US dollar debt.

B.
Significant Changes

Through the end of April 2007, average LME aluminium prices have been higher in 2007 than in 2006, which has had a
positive effect on the Companys profit. The average Australian US dollar exchange rate in 2007 has been higher than in 2006, which has had an adverse effect upon profit. The Brazilian Real and the Euro have strengthened in 2007 which adversely
affects AWACs operating and capital costs.

AWACs operating costs in 2007 are forecast to increase in US$ terms over 2006
levels, due to a weaker US$, higher average energy prices and bauxite and shipping costs.

On May 7,2007, Alcoa made an offer to
acquire all of the outstanding common shares of Alcan Inc. for US$58.60 in cash and 0.4108 of a share of Alcoa common stock for each outstanding common share of Alcan. On May 22, 2007, the board of Alcan recommended to its shareholders that
they reject Alcoas offer.

The offer and withdrawal rights are scheduled to
expire on July 10, 2007, subject to extension. The offer will be subject to a number of customary conditions, including there having been tendered in the offer at least 662/3% of Alcans common shares on a fully diluted basis, receipt of all applicable regulatory approvals, and the absence of material adverse effects.

FINANCIAL INFORMATION

Regarding the regulatory approvals required, the transaction is subject to
review by antitrust authorities in various jurisdictions including the U.S., Canada, the European Union, Australia and Brazil. It also requires foreign investment clearance in Canada, France and Australia.

The agreements between Alumina, Alcoa and AWAC provide for AWAC to be the exclusive vehicle for the parties (Alcoa and Alumina and their
affiliates) investments, operations or participation in the bauxite and alumina businesses. Alcan has interest in several bauxite mines and has an equity share of alumina production of approximately 4.8 mtpy. Under the AWAC agreements, a successful
Alcoa takeover of Alcan would require Alcoa to offer the Alcan bauxite and alumina businesses to AWAC for purchase at their acquisition cost, or if not separately valued, at a value based on an independent appraisal of the businesses.

The manner in which AWAC would fund any purchase of Alcan bauxite and alumina businesses has not yet been considered. The AWAC agreements provide certain
limits on annual equity contributions from Alcoa and Alumina and limits on debt levels of AWAC entities (see Item 10). The funding required by Alumina to acquire its 40% of any Alcan bauxite and alumina businesses acquired by AWAC has not been
determined. However, it is expected that the funding requirement for Alumina would be substantial and would necessitate equity funding as well as debt funding.

B. Constitution

Aluminas corporate organisation and conduct are governed by its corporate constitution (the Constitution). Set forth below is a summary
of the provisions of the principal terms of the Constitution.

Company Objects & Purposes

Alumina is registered as a 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.

The Constitution was adopted by shareholders at the Annual
General Meeting held on April 15, 1999 and subsequently amended by shareholders at the general meeting held on November 29, 2002 and April 21, 2004. The Constitution does not specify Aluminas objects and purposes. Rather, under
section 124 of the Corporations Act, Alumina has the legal capacity and powers of an individual person.

Directors Powers &
Qualifications



|(a) | No director is permitted to vote or be counted in the quorum as a director in respect of any contract or arrangement in which the director has a material interest. Subject to the
Corporations Act, this prohibition can be relaxed or suspended by an ordinary resolution passed in general meeting (rule 85(b)).
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Directors remuneration is to be determined by them from time to time and in such proportions and manner as they determine, provided that the aggregate remuneration paid to
directors in any year must not exceed the amount approved in general meeting (rule 82).
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, every director is
entitled to be paid all reasonable travelling, hotel and other expenses incurred in attending meetings of Alumina and if any director is called upon to perform extra services or provide special professional skill for any purpose of Alumina, the
director may be paid travelling outlays and such additional sum by way of remuneration fixed by the directors (rule 83).



|(c) | Directors may, from time to time, at their discretion raise or borrow any sum or sums of money for the purposes of Alumina with or without security (rule 47).
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | The Constitution does not contain any age limit requirement on the retirement of directors.
|--- | -------------------------------------------------------------------------------------------



|(e) | A director does not need to own shares in Alumina as a qualification for office (rule 80).
|--- | ------------------------------------------------------------------------------------------



|(f) | At each Annual General Meeting one third of the directors (or the nearest number to one third) retire from the office and are subject to re-election. In any event, a director, other
than the managing director, shall retire from office at the conclusion of the third Annual General Meeting after the general meeting at which he or she was elected or re-elected.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Rights & Restrictions Attaching to Each Class of Shares



|(a) | Alumina has only one class of shares, the ordinary class. The rights attached to ordinary shares include the right to dividends in the event that the directors declare them.
Directors may determine that a dividend is payable, fix the amount, the date at which the entitlement accrues, date for payment and the method of payment.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dividends which have not been claimed for one year after having been declared may be invested or otherwise made use of by the directors for the benefit of Alumina until claimed or disposed of according to law (rule
125).



|(b) | The voting right attached to ordinary shares is the right to vote in person, by representative, attorney or proxy in general meeting.
|--- | -------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

2006 FORM 20-F

ADDITIONAL INFORMATION

On a show of hands each shareholder (regardless of the number of shares
held) has one vote. On a poll each shareholder may exercise one vote for each fully paid ordinary share held. In respect of partly paid shares, the shareholder has a vote equivalent to the proportion which the amount paid up bears to the total issue
price of the share at the date the poll is taken.

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.



|(c) | Dividends are only payable out of the profits (rule 114).
|--- | ---------------------------------------------------------



|(d) | In the event of a winding up, ordinary shares rank equally in the division of any surplus.
|--- | ------------------------------------------------------------------------------------------



|(e) | Shareholders cannot redeem ordinary shares.
|--- | -------------------------------------------



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



|(g) | 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 partial takeover bid (see heading Partial Takeover Approval below) or the directors exercise their discretion under Rule 144 in regard to foreign persons (see sub-heading Foreign Persons under the
heading Limitations on the Right to Own Securities).
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(h) | 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 a least three-fourths of the issued ordinary shares within two calendar months from the date of such special meeting (rule 11).
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

General Meetings of the Company

The Board may
convene general meetings of Alumina to be held at such times and places and in the manner determined by the Board (rule 52). No shareholder or director may convene a general meeting unless entitled to do so under the Corporations Act.

Subject to the Corporations Act and the Listing Rules of the Australian Stock Exchange, notices of general meetings convened by the Board may be given in
the form and in the manner determined by the Board (rule 54).

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 representative,
attorney or by proxy (who need not be shareholders of Alumina in their own right).

The quorum for a general meeting is three members
present in person, by proxy or attorney or by representative (rule 57). If within 15 minutes of the time appointed for holding the meeting a quorum is not present, the meeting, if convened by requisition, is dissolved, but in all other cases stands
adjourned to the same day in the next week at the same time and place (rule 58). If at the adjourned meeting a quorum is not present within 15 minutes from the time appointed for holding the meeting, the meeting is dissolved.

Limitations on the Right to Own Securities

Aluminas Constitution does not impose limitations on the right to own securities except those provisions relating to foreign persons who seek to acquire a substantial interest in Alumina.

Foreign Persons

Directors have the
discretion to refuse to allot shares or to register any transfer or transmission of shares to any person, if the allotment, transfer or transmission results in a foreign person (as defined in the Foreign Acquisitions and Takeovers Act 1975 of the
Commonwealth of Australia) acquiring a substantial interest (defined as 15% of the voting power), or two or more foreign persons, alone or together with any associate or associates, acquiring an aggregate substantial interest (defined as 40% of
the voting power) in Alumina (rule 144).

2006 FORM 20-F

ADDITIONAL INFORMATION

Other Takeover Limitations

The rights of non-resident or foreign shareholders to hold or exercise voting rights on Aluminas securities are subject to the Foreign
Acquisitions and Takeovers Act 1975. 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.

Section 50 of the Trade Practices Act 1974 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 a substantial market for goods or services, unless the acquisition is authorised by the Australian Competition and Consumer Commission.

Partial Takeover Approval

In the event that there is
an offer made under a proportional takeover bid (within the meaning given to that expression by Chapter 6 of the Corporations Act) to acquire shares in Alumina, the registration of a transfer giving effect to a contract resulting from
the acceptance of the offer, is prohibited unless and until a resolution to approve the proportional takeover bid is passed in accordance with rule 139 of the Constitution. This resolution is to be voted on at a meeting convened and conducted by
Alumina, of the persons entitled to vote on the resolution. 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. The provision with respect to partial takeover bids (ie rule 139) 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 April 27, 2005.

Disclosure of Share Ownership

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

The directors may at any time by written notice require a member within 14 days of receiving the notice to provide Alumina with full particulars of the name and address of every person who has an interest in any of
the shares held by the member, including full particulars of that interest and of the circumstances by reason of which the other person has that interest (rule 144(c)). On receiving particulars of a person holding an interest in any shares of
Alumina (other than as registered holder), Alumina may give that person written notice requiring that person to provide Alumina with a statement in writing setting out full particulars of that persons interest and of the circumstances by
reason of which that interest is held.

Changes in Share Capital

Alumina by resolution passed in general meeting may from time to time alter its share capital in one or more of the ways provided for, and in the manner prescribed by, the Corporations Act (rule 44).

Subject to the Constitution, Alumina may reduce its share capital (rule 46) or buy back shares (rule 141) in accordance with the Corporations Act.

C. Material Contracts

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

On 21 December 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

ADDITIONAL INFORMATION

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



|(b) | Consideration
|--- | -------------

On 1 January 1995, Alumina paid
to Alcoa approximately US$386 million and transferred 9% of Alcoa of Australia to Alcoa. Alumina contributed an additional sum of approximately US$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 and other necessary but ancillary facilities.

Industrial
chemicals: the research, development, production, marketing and sale of industrial chemicals, comprised initially of the output of the existing Alcoa and Alcoa of Australia 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
1 January 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 to manage a particular operation.

Strategic
Council

The Strategic Council is the principal forum for Alcoa and Alumina to provide direction and counsel to the AWAC entities in
respect of strategic and policy matters. The Alcoa and Alumina 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 (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 US$1 billion; and
|- |  | ---------------------------------------------------------------------------------------



| |  | loans to Alcoa or Alumina, or their respective affiliates by AWAC.

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 is entitled to representation in proportion to its
ownership interest on the board of each entity in the AWAC structure, including Alcoa of Australia. In addition to the Strategic Council meetings, Operation meetings (with representatives from Alcoa and Alumina) are held typically up to
four times a year (usually two in Australia and two at operations/offices outside Australia).

(f) Exclusive Vehicle

AWAC is the exclusive vehicle for the pursuit of Alumina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 (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 Alcoa of Australia in which Alumina 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 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 or Alcoa (as relevant) and therefore the exclusive vehicle provisions of the AWAC agreements would apply.
However, the agreements are silent on the action that Alumina 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, the following limits apply:



|(i) | With respect to amounts up to US$500 million in annual equity requested to be contributed in total by Alcoa and Alumina 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 US$500 million but less than US$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 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 for AWAC or for Alumina, or Alumina 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, Alcoa may fund the Alumina proportionate share and this contribution will be deemed to be a loan by Alcoa to Alumina at the current market rate for Alcoas long-term borrowings. Alumina 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 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 US$1 billion approved by a super majority vote, each party must contribute its proportionate share. However, if Alumina 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 for AWAC or for Alumina. If Alumina 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s place. However, if this occurs, Alumina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 US$1 billion. If Alcoa elects to proceed, Alcoa and Alumina 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 US$500 million and US$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.

(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 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; or
|- |  | ------------------------------



| |  | 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 US$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).

(k) Alumina pre-payment for Alcoa of Australia liabilities

By an amending agreement dated 31 December 1995, Alcoas purchase price for Aluminas 9% of Alcoa of Australia was adjusted, with such adjustment being in full satisfaction of Alumina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 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 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 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 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.

Demerger Deed

(a) Nature of contract

In connection with the demerger, WMC Resources and Alumina Limited entered into the Demerger Deed dated March 5, 2003. The Demerger Deed deals with
transitional and miscellaneous commercial and legal issues arising in connection with the legal and economic separation from WMC Resources.

(b) Key terms

(i) Fundamental demerger principle

The fundamental principle of the separation from WMC Resources is that, following the demerger, WMC Resources has the entire economic benefit, risk and liabilities of all of WMC Resources businesses, companies and assets as if WMC Resources
had owned and operated those businesses, companies and assets at all times. Alumina continues to have the entire economic benefit, risk and liabilities of its companies and assets following the demerger.

(ii) Acknowledgement

Consistent with the
fundamental demerger principle outlined above, WMC Resources and Alumina acknowledged in the Deed that once the demerger was complete, WMC Resources would not have any rights against Alumina, and Alumina would not have any rights against WMC
Resources, except in specified circumstances. Neither WMC Resources nor Alumina has any right to make a claim for loss or damage arising directly or indirectly in relation to the demerger, WMC Resources internal restructure and the operation of WMC
Resources businesses prior to the demerger, unless expressly permitted by the Demerger Deed or any other document or agreement between the parties.

(iii) Business restructure

Aluminas non-AWAC business and companies have been substantially restructured pursuant to a
series of separate restructure agreements prior to the demerger so that an identifiable corporate group has come into existence comprising the companies that constitute WMC Resources assets and our businesses. The Demerger Deed makes provision for:



| |  | the approach to be adopted by the parties to the restructure of WMCs non-AWAC businesses and companies prior to the demerger;
|- |  | ------------------------------------------------------------------------------------------------------------------------------

| |  | the practical, economic and legal effect of WMC Resources separation from Alumina;
|- |  | ----------------------------------------------------------------------------------



| |  | the mechanism under which WMC Resources and Alumina can transfer to the other group any asset or contract which a group member owns or holds after the demerger date
but which at the demerger date was most directly used in the other groups business, or was incorrectly transferred as part of the restructure of WMC Limiteds non-AWAC businesses; and
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | if any asset or share transfers required to establish WMC Resources were not completed prior to the date of execution of the Demerger Deed, the principles in
accordance with which the parties are to conduct their arrangements pending each transfer, so as to ensure that, to the extent possible, each transferee gets the benefit and all risks of the asset or company being transferred as from the accounting
effective date;
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(iv) Accounting separation

The Demerger Deed confirms that, for accounting purposes, Alumina and WMC Resources will be treated as being demerged as from November 30, 2002, or on such other date as may be agreed between WMC Resources and
Alumina Limited, with the intention that it be the date of the closest month end preceding the effective date of the demerger;

(v) Access
to records

Records held by each of WMC Resources and Alumina at the effective date of the demerger that relate to the other are to be
maintained. Each of WMC Resources and Alumina must allow the other to access those records and must notify the other prior to any destruction of those records so that they can be copied or retrieved;

(vi) Financial and tax assistance

WMC
Resources and Alumina will assist each other in relation to future and past financial and tax matters and each will allow the other access to financial and other records in connection with the preparation of tax returns or tax audits by the
Australian Taxation Office of either WMC Resources or Alumina;

(vii) Employees and superannuation

The Demerger Deed addresses matters relating to the transfer of certain of WMC Resources employees to Alumina. Alumina is obliged to indemnify WMC
Resources against all costs and expenses relating to the transfer. WMC Resources and Alumina are each obliged to indemnify the other against all costs and expenses (including claims) relating to any redundancy, retrenchment or termination of a
former Alumina employee or employee of WMC Resources (as applicable);

In accordance with the fundamental demerger principle, each of WMC
Resources and Alumina are required to meet all costs relating to the provision of retirement savings or retirement income benefits and other related benefits for their employees. The Demerger Deed also requires Alumina to assume responsibility for
the superannuation arrangements of those employees transferring to it from WMC Resources;

(viii) Use of intellectual property

The Demerger Deed sets out the general principles that determine ownership of intellectual property by WMC Resources and Alumina (other than trade
marks and business names). The Demerger Deed also sets out the restrictions on the use of jointly-owned intellectual property.

Under the
Demerger Deed, Alumina is required as soon as practicable, and in any event within one month, after the demerger date to cease the use of the WMC name (and derivatives) and the WMC logo and to arrange for the change of
Alumina group company names including the WMC name (or derivatives);

(ix) Litigation management

WMC Resources and Alumina will assist each other in relation to the management of current and new litigation matters involving Alumina (other than in
respect of litigation between WMC Resources and Alumina). Each of WMC Resources and Alumina indemnifies the other in respect of liability or loss suffered in connection with a claim where that liability relates to the business of the other; and

Transitional Services Agreement

(a) Nature of contract

In connection with
the demerger, WMC Resources and Alumina entered into the Transitional Services Agreement dated December 18, 2002. Under the agreement, WMC Resources provided, or procured the provision of, certain services to the Alumina group for a period of

(b) 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). The Charter of the United Nations Act 1945 (Cth) and the Charter of the United Nations (Terrorism and Dealings with Assets) Regulations 2002 (Cth) also regulate certain transactions.

Under the Foreign Acquisitions Act, any acquisition or issue of shares (including the acquisition of an option to acquire shares) 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 level of foreign ownership 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.

Transactions that involve a transfer 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 Charter of the United Nations (Terrorism and Dealings with Assets) Regulations 2002 (Cth) (the Terrorism
Regulations) require ministerial approval.

The Charter of the United Nations Act 1945 (Cth) enables Australia to give effect to
decisions made by the United Nations Security Council. The Terrorism Regulations give effect to United Nations Security Council Resolutions 1390 (2002), 1373 (2001), 1333 (2000) and 1267 (1999), which impose obligations on member states to
prevent use of or dealings with assets by, or making of assets available to, certain persons and entities engaged in terrorist acts or who are subject to international sanctions.

The Terrorism Regulations apply to the Taliban, Osama bin Laden and any
member of the Al-Qaida organization pursuant to the United Nations Security Council Resolution 1390 (2002). 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 list maintained by the Minister for Foreign Affairs
of the Commonwealth of Australia includes the Kurdistan Peoples Congress, the Al-Aqsa Foundation, Ansar al-Islam and the Orange Volunteers. Regulations most recently enacted by the Governor General have applied to former Liberian President
Charles Taylor and his associates.

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 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 particular circumstances. This discussion relies in part on representations by the Depositary in the Deposit Agreement and related documents.

Commonwealth of Australia Taxation

With effect
from July 1, 2002, Australia rewrote dividend imputation legislation system relating to company tax. Broadly, the legislation rewrites the old dividend system. It is intended to produce a similar tax outcome as the old system with some noted
differences. 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 paid out of profits which have borne Australian corporate tax (ie. to which franking credits have been allocated) while unfranked dividends are 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. Notices are provided to shareholders which specify the
amount (if any) of dividend withholding tax deducted.

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. These rules apply from July 1, 2001.

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 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 and domestic law. 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.

##### Table of Contents

2006 FORM 20-F

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 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:



| |  |  | for disposals on or before December 12, 2006, if the person (together with associates, if any) owns or owned ADS and/or Ordinary Shares at any time during the
period of five years preceding the disposal, representing 10% or more of our issued share capital (excluding share capital carrying no right to participate beyond a specified amount in distribution of profits or capital); or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for disposals on or after December 12, 2006, if the person (together with associates, if any) held 10% or more (by value) of the issued Alumina 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 Australian Real Property. Australian Real
Property will include mining rights.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.

Neither the issue or transfer of an ADS or our Ordinary Shares or the payment 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 or the transfer of our Ordinary Shares.

This discussion is based on the Internal Revenue Code of 1986, as amended (the Code), existing and proposed regulations, published rulings
and court decisions, all as currently in effect, as well as 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). These laws are subject to change, possibly on a retroactive basis.

You are a U.S. person if
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; or

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.

For purposes of this discussion an eligible U.S. holder is a U.S. person that:

is a resident of the United States for purposes of the Treaty;

does not maintain, for purposes of the Treaty, a permanent establishment or fixed base in Australia to which Ordinary Shares or ADS are attributable and through which the U.S. person carries on or has carried on
business (or, in the case of an individual, performs or has performed independent personal services); and

is otherwise eligible for
benefits under the Treaty with respect to income or gain from ordinary shares or ADS.

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 to which you may be subject. In particular you should confirm your status as an eligible US holder with your advisors and should discuss any possible consequence of failing to qualify as an eligible U.S. holder.

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. Subject to the passive foreign investment company rules discussed below, to the extent that the amount of any 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. If you are a
corporation you generally will not be entitled to claim dividends received deduction with respect to distributions paid with respect to your Ordinary Shares or ADS.

##### Table of Contents

2006 FORM 20-F

ADDITIONAL INFORMATION

The amount of the dividend distribution that you must include in your income
will be the US dollar value of the Australian dollar payments made, determined at the spot Australian dollar/US dollar rate on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted
into US dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into US dollars will be treated as ordinary
income or loss. The gain or loss generally will be income or loss from sources within the United States for foreign tax credit limitation purposes.

With effect for dividends paid from January 1, 2003 through December 31, 2010, the United States reduced the maximum tax rate on certain qualifying dividend distributions to 15% for non corporate U.S. persons. In order for
dividends paid by foreign corporations to qualify for the reduced 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. The Company 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.

The company believes that dividends on ADS will qualify for these
lower tax 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.

Dividends paid to eligible 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, but dividends paid in taxable years beginning before January 1, 2007 generally will be passive income or financial services income and dividends paid in taxable years beginning after December 31, 2006
will, depending on your circumstances, be passive income or general income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to you. Dividends
qualifying for the special 15% maximum U.S. tax rate are subject to special rules in determining a taxpayers foreign tax credit limitation.

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 noncorporate U.S. person is generally taxed at a maximum rate of 15% on long term capital gain that is recognized on or after May 6, 2003 and before January 1, 2009. Any capital gain or loss so realized will
generally be United States source gain or loss. Your ability to deduct capital losses is subject to limitations.

Passive Foreign Investment Company
Rules

Alumina 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. Moreover, the application of the PFIC rules to a corporation such as Alumina
that is primarily engaged in the active business of mining and processing metals is not entirely clear.

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.

2006 FORM 20-F

ADDITIONAL INFORMATION

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 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.

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. 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.

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

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative Information about Market Risk

Continuing operations

Aluminas policy currently is not to hedge its commodity or currency exposure other than to secure the Australian dollar value of foreign currency bank accounts. This policy will be reviewed periodically. AWAC has previously sought to
manage its exposure to both the aluminium price and the A$/US$ exchange rate through the use of derivative products. There were no aluminium hedge positions in place at December 31, 2006.

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. Energy price risk is managed through short-term commodity hedges. AWAC does not hedge its aluminium price risk.

Commodity Price Risk

A table showing the movement in the selling price of aluminium over the last five years is set
out below.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Exchange Rate
Risk

Foreign currency risk relates to Aluminas exposure to changes in exchange rates. Aluminas revenue streams
were significantly derived from the sale of its commodity production in US dollars and the amount of Australian dollar revenue it would receive fluctuated with the moving AUD/USD exchange rate.

Alumina Limiteds 2007 earnings sensitivities, based on 2006 earnings and 2006 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 A$7 million.

Interest rate risk

Interest rate risk refers to Aluminas exposure to movements in interest rates. Alumina is primarily exposed to interest rate risk on its outstanding
interest bearing liabilities, primarily determined by the US$ 3 month LIBOR rate. As the interest rates fluctuate, the amount of interest payable on debt balances where the interest rate is not fixed will also fluctuate.

Alumina Limited established a new US$700 million multi-currency one, three and five year debt facility in mid-2006.

As at December 31, 2006 the group had short term bank debt outstanding totaling A$380.2 million or US$300.0 million and long term debt outstanding
totaling A$207.9 million or US$164 million.

As at December 31, 2005 the group had short term bank debt outstanding totaling A$478.7
million or US$351.0 million which was refinanced and converted to medium and short term debt in July 2006.

Interest rate and cross-currency swaps

At December 31, 2006 and at December 31, 2005, Alumina had no outstanding interest rate hedging contracts in relation to its
debt.

As at December 31, 2006 and at December 31, 2005, the group had no cross currency swaps in place.

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 rate and interest rate risk is discussed in Item 5B Operating and Financial Review and Prospects  Liquidity and Capital Resources.

ITEM 15. CONTROLS AND PROCEDURES

A. Disclosure Controls and Procedures

Under the supervision and with the participation of Aluminas Chief Executive Officer and Chief Financial Officer, management conducted an
evaluation of the effectiveness of Alumina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,
2006. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective 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 the Companys management, as appropriate to allow timely decisions regarding disclosure.

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

Alumina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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s
management under the supervision 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 framework in Internal
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, our management has concluded that Aluminas internal control over financial reporting was effective as
of December 31, 2006.

2006 FORM 20-F

Managements assessment of the effectiveness of Aluminas internal control over financial reporting as of December 31, 2006 has been audited by PricewaterhouseCoopers, an independent registered public accounting firm, as
stated in their report which appears on page F-43 herein.

C. 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, 2006 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 Mr Donald M Morley is an
audit committee financial expert as required by the New York Stock Exchange listing standards. Mr Morley is not independent under New York Stock Exchange rules until October 31, 2005 which was three years from the end of his
employment with the Company. Mr Morley is from November 2005 considered independent under the independence requirements of the New York Stock Exchange corporate governance standards. Although the board of directors has determined that Mr Morley 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 or to determine that our financial statements and disclosures are complete and accurate. 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 has adopted a code of conduct that applies to its directors, executive
officers and employees. The Code of Conduct covers matters such as compliance with laws and regulations, protection of Aluminas assets, conflict of interest, protection of corporate privilege of information, maintenance of records and
reporting of questionable activities in good faith.

During 2005 the following amendments were made to Alumina Limiteds code of
conduct:



| |  |  | Any request for a waiver of the provisions of this Code may only be considered by the Companys Board of Directors. Any waiver granted will be promptly
disclosed on the Companys website.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Any suspected violations of this Code should be reported promptly to the Chairman of the Companys Board of Directors. Violations will be investigated by the
Board or persons designated by the Board and appropriate action will be taken in the event of any violations of the Code.

financial report for the year ended 31 December 2006 has been prepared in accordance with Australian Equivalents to International Financial Reporting Standards (AIFRS), other authoritative pronouncements of the Australian Accounting Standards
Board, Urgent Issues Group Interpretations and the Corporations Act 2001.

Compliance with IFRS

Australian Accounting Standards include AIFRS. Compliance with AIFRS ensures that the consolidated financial statements and notes of Alumina Limited
comply with International Financial Reporting Standards (IFRS). The parent entity financial statements and notes also comply with IFRS except that it has elected to apply the relief provided to parent entities in respect of certain disclosure
requirements contained in AASB 132 Financial Instruments: Disclosure and Presentation and AASB 124 Related Party Disclosures.

Adoption of AASB 132 and AASB 139 as of January 1, 2005

In 2005, the Company elected to apply the exemption from
restatement of comparatives for AASB 139 Financial Instruments: Recognition and Measurement, and therefore continues to apply Australian GAAP rules to derivatives, financial assets and financial liabilities and hedging relationships for 2004.

Historical cost convention

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

Critical accounting estimates

The
preparation of financial statements in conformity with AIFRS 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.



|B | PRINCIPLES OF CONSOLIDATION
|- | ---------------------------

(i)
Subsidiaries

The consolidated financial report is prepared on a consolidated entity basis for Alumina Limited (parent entity) and the
entities it controls (controlled entities). AIFRS defines controlled entities as existing where the Company has the power, directly or indirectly, to govern the financial and operating policies of an entity so as to obtain benefits from its
activities, generally accompanying a shareholding of more than one-half of the voting rights. The financial statements of the subsidiaries are included in the consolidated financial report, from the date that control commences until it ceases. All
material controlled entities in the consolidated entity are companies. The economic entity consisting of Alumina Limited and its controlled entities is referred to in the financial report as the Group. In preparing the consolidated
financial statements, the effects of all transactions between entities within the Group are eliminated in full, including unrealised profits and losses on transactions with associates accounted for on an equity basis.

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

Where control of an entity is obtained during a financial year, its results are included in the consolidated income statement from the date on which
control commences. Where control of an entity ceases during a financial year, its results are included for that part of the year during which control existed.

Minority interests in the results and equity of subsidiaries are shown separately in the consolidated income statement and balance sheet respectively.

(ii) Associates

Associates are those
entities over which the consolidated entity exercises significant influence but not control over the financial and operating policies, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are
accounted for in the financial statements of the parent entity using the cost method and in the consolidated financial statements using the equity method of accounting, after initially being recognised at cost. The consolidated entitys
investment in associates includes goodwill (net of any accumulated impairment loss) identified on acquisition.

The Groups share of
its associates post acquisition profits or losses is recognised in the income statement, and its share of post-acquisition movements in reserves, is recognised in reserves after aligning back to Group accounting policies. The cumulative
post-acquisition movements are adjusted against the carrying amount of the investment. Dividends receivable from associates are recognised in the parent entitys income statement, while in the consolidated financial statements they 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.

The Group uses the cost method to account for any entities of which it holds less than 20% ownership.

|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 national income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences between the tax
bases of assets and liabilities and their carrying amounts in the financial statements, and changes attributable to unused tax losses.

Deferred tax assets and liabilities are recognised for temporary differences using the balance sheet liability method, at the tax rates expected to apply when the assets are recovered or liabilities are settled, based on those tax rates
which are enacted or substantively enacted for each jurisdiction at reporting date. The relevant tax rates are applied to the cumulative amounts of deductible and taxable temporary differences to measure the deferred tax assets or liabilities. An
exception is made for certain temporary differences arising from the initial recognition of an asset or a liability. No deferred tax asset or liability is recognised in relation to these temporary differences if they arose in a transaction, other
than a business combination, that at the time of the transaction did not affect either accounting profit or taxable profit or loss.

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.

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

Additional income 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 under the applicable legislation as of 1 January 2004.

The head entity, Alumina Limited, and the controlled entities in the tax consolidated Group continue to account for their own current and deferred tax amounts. These tax amounts are measured using the separate tax
payer within 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.

Assets and liabilities arising under tax funding agreements with the tax consolidated entities are recognised as amounts receivable from or payable to other entities in the Group. Details of the tax funding agreement
are disclosed in Note 7.

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.



|D | FOREIGN CURRENCY TRANSLATION
|- | ----------------------------

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 those entities operate (the functional currency). The consolidated financial statements are presented in Australian dollars, which is Alumina Limiteds functional and presentation
currency.

Transactions and balances

Foreign currency transactions are initially translated into Australian 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 income statement, except when deferred in equity as qualifying cash flow hedges and
qualifying net investment hedges.

Controlled foreign entities

The results and financial position of all the Group entities 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 for each income statement are translated at average 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); and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | all resulting exchange differences are recognised as a separate component of equity.
| | - |  | ------------------------------------------------------------------------------------

On consolidation, exchange differences arising from the translation of any net investment in foreign entities, and of borrowings and other currency
instruments designated as hedges of such investments, are taken to the translation reserve in shareholders equity. When a foreign operation is sold or borrowings are repaid, a proportionate share of such exchange differences are recognised in
the income statement 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.

|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
|-- | ------------------------------------------------------



|E | PROPERTY, PLANT AND EQUIPMENT
|- | -----------------------------

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.

Leased Assets

The company leases office facilities under an operating lease agreement. Payments made under this agreement are recognised in the income statement on a
straight-line basis over the term of the lease. Lease incentives received are recognised in the income statement 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 doubtful debts, which in practice will equal the amounts receivable upon settlement. Collectibility of trade debtors is reviewed on an ongoing basis. Debts which
are known to be uncollectible are written off. A provision for doubtful receivables is established when there is objective evidence that the Group will not be able to collect all amounts due according to the original terms of receivables. The amount
of the provision is the difference between the assets carrying amount and the present value of estimated future cash flows, discounted at the effective interest rate. The amount of the provision is recognised in the income statement.



|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. Bank overdrafts are shown within borrowings in current liabilities on the balance sheet.



|H | IMPAIRMENT OF ASSETS
|- | --------------------

Assets that have an
indefinite useful life are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not
be recoverable. 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).



|I | ACQUISITION OF ASSETS
|- | ---------------------

The purchase method of
accounting is used for all acquisitions of assets (including business combinations) regardless of whether equity instruments or other assets are acquired. Cost is measured as the fair value of the assets given, equity instruments issued or
liabilities incurred or assumed at the date of exchange plus costs directly attributable to the acquisition. Where equity instruments are issued in an acquisition, the value of the instruments is their published market price as at the date of
exchange, unless the published market price is an unreliable indicator of fair value and other evidence and valuation methods provide a more reliable measure of fair value. Transaction costs arising on the issue of equity instruments are recognised
directly in equity.

Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured
initially at their fair values at the acquisition date, irrespective of the extent of any minority interest. The excess of the cost of acquisition over the fair value of the Groups share of the identifiable net assets acquired is recorded as
goodwill (refer to Note 1(j)). If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognised directly in the income statement, but only after a reassessment of the identification
and measurement of the net assets acquired.

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.

|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
|-- | ------------------------------------------------------



|J | INTANGIBLE ASSETS
|- | -----------------

Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Groups share of the net identifiable assets of the acquired
subsidiary/associate at the date of acquisition. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill on acquisitions of associates is included in investments in associates.

Goodwill acquired in business combinations is not amortised. Instead, goodwill is tested for impairment annually or more frequently if events or changes
in circumstances indicate that it might be impaired, and is carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

Goodwill is allocated to cash-generating units for the purpose of impairment testing.

If the cost of acquisition is less than the Groups share of the fair value of the identifiable net assets of the subsidiary acquired, the difference
is recognised directly in the income statement, but only after a reassessment of identification and measurement of net assets acquired.



|K | DEPRECIATION OF PROPERTY, PLANT AND EQUIPMENT
|- | ---------------------------------------------

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



|                                     |  |        
|------------------------------------ |  | -------
|Office furniture                     |  | 8 years
|Computers and other office equipment |  | 4 years



|L | BORROWINGS
|- | ----------

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

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.



|M | BORROWING COSTS
|- | ---------------

Borrowing costs comprise interest
payable on borrowings calculated using the effective interest rate method and certain foreign exchange differences arising from foreign currency borrowings. 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.



|N | 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.



|O | REVENUE
|- | -------

Revenue is measured at the fair value of
the consideration received or receivable. Amounts disclosed as revenue are net of returns, trade allowances and duties and taxes paid.

Interest income is recognised in the income statement as it accrues, using the effective interest method. Dividend income is recognised in the income statement on the date the entitys right to receive payments is established.

|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
|-- | ------------------------------------------------------



|P | EMPLOYEE BENEFITS
|- | -----------------



| | (i) | Salaries and annual leave
| | --- | -------------------------

Liabilities for salaries
and annual leave are recognised in current provisions (i.e. expected to be settled in 12 months), 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 using the projected unit credit method.
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.

Shares options granted before or after 7 November 2002 and
vested before 1 January 2005

No expense is recognised in respect of these options. The shares are recognised when the options are
exercised and the proceeds received allocated to share capital.

Shares options granted after 7 November 2002 and vested after
1 January 2005

The fair value of options granted 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 options.

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
option, the vesting and performance criteria, the impact of dilution, the non-tradeable nature of the option, 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 option.

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

The market value of shares issued to employees for no cash consideration under the WMC employee share scheme
is recognised as an employee benefits expense with a corresponding increase in equity when the employees become entitled to the shares.

Non-market vesting conditions are included in assumptions about the number of options that are expected to become exercisable. At each balance sheet date, the entity revises its estimate of the number of options that are expected to become
exercisable. The employee benefit expense recognised each period takes into account the most recent estimate.



| | (iv) | Superannuation
| | ---- | --------------

Since 27 July 2001, all
employer contributions and ongoing management of employees superannuation entitlements have been managed by the WMC Superannuation Plan, an independently managed sub-plan of the Plum Superannuation Fund, except where the relevant employees
elect for those contributions to be paid to an alternate fund. Alumina employees are members of a sub-plan of the WMC Superannuation Plan, created specifically for Alumina. The plan is an accumulation category plan which offers a minimum company
contribution (subject to certain cashing out options and legislation) of 9 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 operating cost.



| | (v) | 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 government 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.

When the calculation results in plan assets exceeding liabilities to the Group, the
recognised asset is limited to the net total of any unrecognised actuarial losses and past service costs and the present value of any future refunds from the plan or reductions in future contributions to the plan.

When the benefits of a plan are improved, the portion of the increased benefit relating to past service by employees is recognised as an expense in the
income statement on a straight-line basis over the average period until the benefits become vested. To the extent that the benefits vest immediately, the expense is recognised immediately in the income statement.

All actuarial gains and losses are recognised in earnings of the associates.

|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
|-- | ------------------------------------------------------

Past service cost is the increase in the present value of the defined benefit obligation for employee services in prior periods, resulting in the current period from the introduction of, or changes to, post-employment benefits or other
long-term employee benefits. Past service costs may either be positive (where benefits are introduced or improved) or negative (where existing benefits are reduced).



|Q | 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. The method of recognising gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the
nature of the item being hedged.

The Group documents at the inception of the 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 value or cash flows of hedged items.

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 equity. The ineffective portion is recognised immediately in the income statement. The gain or loss on hedging instruments relating to the effective portion
of the hedge that has been recognised directly in equity shall be recognised in profit or loss on disposal of the foreign operation.

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 equity in the hedging reserve. The gain or loss relating to the ineffective portion is recognised immediately in the income statement within other income or other expense.

Amounts accumulated in equity are recycled in the income statement in the periods when the hedged item will affect profit or loss (for instance when the
forecast sale that is hedged takes place).

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 the income statement. When a forecast transaction is no longer
expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the income statement.

Embedded
Derivatives

Under AIFRS, sale and purchase contracts may be considered to have financial derivative instruments embedded within them.
This occurs 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 LME aluminium price at the time. Such contracts are
considered to have embedded derivatives. AIFRS requires the future purchases under these contracts to be marked-to-market at each balance date on the basis of the then-current best indicator of future LME aluminium price over the remaining terms of
the contracts. The embedded derivative in relevant AWAC contracts has been assessed and marked to market on the balance date. Changes in the mark to market valuation from the opening of the period to the balance date are accounted for as gains or
losses, as appropriate, in the accounts of the relevant AWAC entity. Alumina Limited accounts for its share of such transactions within its equity share of net profits of associates.



|R | 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.



|S | 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.



| | (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 shares assumed to have been issued for no consideration in relation to dilutive potential ordinary shares.

|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
|-- | ------------------------------------------------------



|T | SEGMENT REPORTING
|- | -----------------

A business segment is a group of
assets and operations engaged in providing products or services that are subject to risks and returns that are different to those of other business segments. A geographical segment is engaged in providing products or services within a particular
economic environment and is subject to risks and returns that are different from those of segments operating in other economic environments.



|U | 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 and refineries 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 costs are estimated on the basis of a closure model. The cost
estimates are calculated annually during the life of the operation to reflect known developments, and are subject to regular reviews.

The
amortisation or unwinding of the discount applied in establishing the net present value of provisions is charged to the profit and loss account in each accounting period. The amortisation of the discount is shown as a financing item. 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.



|V | CONTRIBUTED EQUITY
|- | ------------------

Ordinary shares are classified
as equity.

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



|W | NEW ACCOUNTING STANDARDS
|- | ------------------------

Certain new accounting
standards have been published that are not mandatory for 31 December 2006 reporting periods. The Groups assessment of the impact of these new standards and interpretations is set out below:



| | i) | AASB 7 Financial Instruments: Disclosures
| | -- | -----------------------------------------

AASB 7
is applicable to annual reporting periods beginning on or after 1 January 2007. The Group has not early adopted this standard. Application of this standard will not affect any of the amounts recognised in the financial statements, but will
impact the type of information disclosed in relation to the Groups financial instruments.



| | ii) | AASB Interpretation 10 Interim Financial Reporting and Impairment
| | --- | -----------------------------------------------------------------

AASB Interpretation 10 applies to annual reporting periods beginning on or after 1 November 2006 prohibiting the reversal of an impairment loss recognised in an interim period in respect of goodwill, an
investment in an equity instrument, or a financial asset measured at cost. The Group has not early adopted this standard. Application of this standard will not affect any of the amounts recognised in the financial statements.



|X | ROUNDING OF AMOUNTS
|- | -------------------

The company is of a kind
referred to in Class Order 98/0100, issued by the Australian Securities and Investments Commission, relating to the rounding off of amounts in the financial report. Amounts in the financial report have been rounded off in accordance with
that Class Order to the nearest hundred thousand dollars, or as otherwise indicated.

|2. | FINANCIAL RISK MANAGEMENT
|-- | -------------------------

The Groups
activities expose it to a variety of financial risks including market risk, credit risk and interest rate risk. The Groups overall risk management program focuses on the unpredictability of financial markets and seeks to minimise potential
adverse effects on the financial performance of the Group.

Risk management is carried out by the Chief Financial Officer under policies
approved by the Board of Directors.



| | (a) | Market risk
| | --- | -----------



| | (i) | Foreign exchange risk
| | --- | ---------------------

Foreign exchange risk arises
when future commercial transactions and recognised assets and liabilities are denominated in a currency that is not the entitys functional currency. The Group manages this risk by borrowing in US dollars to provide a hedge for its US dollar
denominated assets.

The Group operates internationally and is exposed to foreign exchange risk arising from exposures to various
currencies, especially to the US dollar. The Group does not hedge its exposures other than through the near-term forward purchase of currency to meet operating requirements.



| | (ii) | Price risk
| | ---- | ----------

The Group is exposed to commodity price
risk through its investment in the AWAC joint venture. AWAC manages commodity price risk through long-term purchase contracts for some input costs. Energy price risk is managed through short-term commodity hedges. During 2006, AWAC did not hedge its
aluminium price risk.



| | (b) | Credit risk
| | --- | -----------

The Group 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 the AWAC joint venture. The Group has policies in place to ensure that sales of products and
services are made to customers with an appropriate credit history. Derivative counterparties and cash transactions are limited to financial institutions of high credit quality. The Group has policies that limit the amount of credit exposure to any
one financial institution.



| | (c) | Cash flow and fair value interest rate risk
| | --- | -------------------------------------------

The
Groups interest-rate risk arises from short-term borrowings. When managing interest rate risk, the Group seeks to reduce the overall cost of funds. A preference for floating rate exposure is sought by the Group.



| | (d) | Liquidity risk
| | --- | --------------

Prudent liquidity 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 reasonable expected forward cash requirements.

|3. | CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS
|-- | ---------------------------------------------

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 entity and that are believed to be reasonable under
the circumstances. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are disclosed below.

Embedded derivatives

The Group has
recognised a liability for derivative financial instruments through its equity investment in AWAC in accordance with AASB 139 Financial Instruments: Recognition and Measurement. In the determination of the fair value of this liability, AWAC
has applied management estimates for long term commodity prices.

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 AASB 119 Employee Benefits. These valuations require actuarial assumptions to be made.

Asset retirement obligations

The estimated costs of rehabilitating mined areas and restoring operating sites is reviewed
annually and fully provided at the present value. The amount of obligations recognised by AWAC includes the costs of mined 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.

For mined 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.

Notes to and forming part of the financial statements for the year ended 31 December 2006



|7. | INCOME TAX EXPENSE (continued)
|-- | ------------------------------

The benefits for
tax losses will only be obtained if:



| | (i) | the consolidated entity derives future assessable income within the prescribed time limit of a nature and of an amount sufficient to enable the benefit from the deductions for the
losses to be realised;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the consolidated entity continues to comply with the conditions for deductibility imposed by the law; and
| | ---- | ---------------------------------------------------------------------------------------------------------



| | (iii) | no changes in tax legislation adversely affect the consolidated entity in realising the benefit from the deductions for the losses.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------



|(d) | Tax consolidation legislation
|--- | -----------------------------

Alumina Limited and
its wholly-owned Australian subsidiaries have implemented tax consolidation under the applicable legislation as of 1 January 2004. The accounting policy in relation to this legislation is set out in Note 1(c).

As provided for under the tax consolidation legislation, the entities in the tax consolidated Group entered into a tax sharing agreement to limit the
joint and several liability of the wholly-owned entities in the case of a default by the head entity, Alumina Limited.

The entities have
also entered into a tax funding agreement under which the wholly-owned entities fully compensate Alumina Limited for the assumption of any current tax payable and are compensated by Alumina Limited for any current tax receivable, and for any
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. The funding amounts
are recognised as current intercompany receivables or payables.

The parent entity has not recognised tax balances relating to subsidiary
losses in 2005 and 2006, as these losses did not meet the recognition criteria.

|(e) | Accounting policies
|--- | -------------------



|i. | The audited consolidated financial statements of the entities forming AWAC are prepared in accordance with US Generally Accepted Accounting Principles (US GAAP). Except for Alcoa of
Australia Limited (AofA), the reported profit after tax of AWAC is based on these US GAAP financial statements. Financial statements in US dollars have been translated to Australian dollars using average exchange rates for the
period for profit and loss items, and closing rates for balance sheet items. Adjustments are made for accounting policies not allowed under Australian equivalents to International Financial Reporting Standards. 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 each refinery, and to reverse any excesses or
shortfalls of the superannuation fund assets over accrued membership benefits taken to the Income Statement.

|ii. | Included in the equity accounted carrying amount at which the equity investment in AWAC is recorded, are amounts for goodwill, including profits realised in forming AWAC. Goodwill
is tested for impairment annually or more frequently if events or changes in circumstances indicate that it may be impaired, and is carried at cost less accumulated impairment losses. Refer Note 1(j).

Unascertainable unsecured contingent liabilities

Various lawsuits and claims and proceedings 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 be determined now because of the considerable uncertainties that exist. Therefore, it is possible that
results of operations or liquidity in a particular period could be materially affected by certain contingencies. However, based on currently available facts, management believes that the disposition of matters that are pending or asserted will not
have a materially adverse effect on the financial position or liquidity of AWAC.

Pursuant to the terms of the AWAC 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 pre-formation liabilities, such as existing environmental conditions, to the extent of their
pre-formation ownership of the company or asset with which the liability is associated.

|(a) | Prior to the demerger, the establishment of the WMC Employee Share Scheme was approved by shareholders at the Annual General Meeting held on 12 December 1987. Under the Scheme
a number of share plans operated. Fully paid shares, partly paid shares and share options were granted to employees since establishment of the Scheme. These options remained exercisable until 30 November 2006.

There is no ongoing option plan available to Alumina Limited directors or employees.

|(b) | Ordinary shares 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.

19. SHARE-BASED PAYMENTS

(a) 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.

Generally, each offer has a three year performance period, with performance
tested at the end of this period to determine the number of performance rights to vest to the employee, if any. 50% of the performance rights not vested at the three year performance test can be re-tested six months after the end of the three year
performance period. The performance testing is carried out by an independent party and is based on the relative Total Shareholder Returns (TSR) of Alumina Limited, compared to two specific comparator groups.

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 Directors decide otherwise.

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

(b) Employee Share Scheme

The establishment of the WMC Employee Share Scheme was approved by shareholders at the Annual General Meeting held on 12 December 1987. Under the Scheme a number of share plans have operated. Fully paid shares,
partly paid shares and share options have been granted to employees since establishment of the Scheme. This Scheme expired on 30 November 2006.

Employee option plan (Expired 30 November 2006)

All permanent employees (including executive directors) of Alumina Limited and its
subsidiaries who were employed, prior to demerger, by the company or a subsidiary were eligible to participate in the WMC Employee Share Scheme and be offered options for fully paid shares. Options allotted, prior to the demerger, to Alumina
employees were exercisable until expiry of the scheme on 30 November 2006.

The major provisions of the option plan provided that the employee may
request that the options be converted after one year from the date of allotment. Options were exercisable at their strike price. Restrictions existed for certain employees on the number of options which can be exercised in any year. If the request
to convert the options to shares were not made, the Company made the call at the completion of five years from the date of issue or termination of employment. Certain designated officers were not permitted to exercise options or buy and sell shares
in the period between the end of the companys half or full financial year and the release of the respective result.

Employee share options carried
no rights to dividends and no voting rights. When exercised, each option resulted in a beneficial entitlement to one fully paid ordinary share.

ALUMINA LIMITED AND CONTROLLED ENTITIES

Notes to and forming part of the financial statements for the year ended 31 December 2006

19. SHARE-BASED
PAYMENTS (continued)

Stock appreciation plan (Expired 30 November 2006)

In various years since approval of the WMC Employee Share Scheme in 1987, until the demerger of the company, the company established stock appreciation plans (SAPs) for the benefit of employees mainly in
countries outside Australia. The purpose of the SAPs was to provide such employees, who due to securities law constraints were not eligible to participate under the Options Plans, with benefits similar to those conferred by the Option Plans. This
plan expired on 30 November 2006.

Under the terms of the WMC Stock Appreciation Plan (SAP), employees were invited to apply for the grant by WMC
Limited. The employees were not required to pay any amount for the grant, but each WMC Limited SAP has a notional allotment exercise price, equal to the weighted average sale price of WMC shares on the ASX on the trading day that the invitation to
apply for the WMC Limited SAP was made to the employee. Subject to certain exceptions, the WMC Limited SAP was not able to be redeemed until after a period of 12 months from the date of allotment and lapse on the fifth anniversary of the date of
allotment. Upon redemption of a WMC Limited SAP before its expiry by the holder, the holder was entitled to a payment equal to the difference between the closing price of WMC Limited (or, post-demerger Alumina Limited) on the ASX on the trading day
immediately before redemption, and the notional allotment price (assuming the former is higher).

Set out below are summaries of allotments made under
SAPs:

|Current payables                |  | 14    |  | 12.7                |  | 12.7       |  | 3.1            |  | 3.1

The following methods and assumptions were used to estimate the fair value of each class of
financial instruments for which it is practicable to estimate a value:

Cash and cash equivalents

The carrying amount approximates fair value because of the short maturity of these instruments.

Debtors and creditors

Other
current debtors and creditors mainly represent financial obligations incurred in exchange for goods and services provided and received by the Group in the normal course of its operations, net of provisions for doubtful debts. Due to the short term
nature of these financial obligations, their carrying values are estimated to equal their fair values.

|25. | CONTINGENT LIABILITIES
|--- | ----------------------

There were no contingent
liabilities as at 31 December, 2006 other than those disclosed in Note 12(g) in relation to AWAC and cross guarantees given by Alumina Limited and Alumina International Holdings Pty. Ltd are described in Note 24. There are no deficiencies of
assets in any of these companies.

These guarantees may give rise to liabilities in the parent entity if the subsidiary does not meet their
obligations under the terms of the overdrafts, loans or other liabilities subject to the guarantees.

No material losses are anticipated in
respect of any of the above contingent liabilities.

Prior to the demerger, WMC Finance (USA) Limited (Finance USA) (a
wholly-owned subsidiary of WMC Resources) had approximately US$800 million of long dated bonds issued in four separate tranches (having maturities in 2003, 2006, 2013 and 2026), on issue (the US Bonds)

The obligations of Finance (USA) under the US Bonds were guaranteed by Alumina. In connection with the demerger, Finance USA tendered to repurchase the US
Bonds remaining outstanding. The aggregate amount of outstanding bonds not repurchased was comprised as follows of:



| |  |  | US Bonds due November 15 2013  US$3,658,000
| | - |  | --------------------------------------------



| |  |  | US Bonds due December 1, 2026  US$115,000
| | - |  | ------------------------------------------

These outstanding US Bonds continue to be guaranteed by Alumina. The duration of the guarantee is unlimited, and continues as long as amounts are outstanding under the US Bonds.

Under the demerger deed, Alumina and WMC Resources indemnify each other in respect of certain liabilities. Alumina would be entitled to reimbursement from
WMC Resources for amounts paid by Alumina under the guarantee in respect of the US Bonds.

Pursuant to a Power Purchase Agreement dated
November 27, 1998 between WMC Resources, WMC Limited (as it then was) and Southern Cross Energy, Alumina has undertaken to provide Southern Cross Energy with a guarantee or letter of credit for WMCRs payment for power in the event that
WMCRs gross assets fall below $250 million in any year.

ALUMINA LIMITED AND CONTROLLED ENTITIES

Notes to and forming part of the financial statements for the year ended 31 December 2006



|32. | RECONCILIATION TO US GAAP
|--- | -------------------------

The accounting
policies and accounting standards under which the consolidated financial statements of the Group are prepared are in accordance with A-IFRS. The major differences between A-IFRS and US GAAP are summarized and reconciled below as relates to the
Company:



|(a) | Associates
|--- | ----------

The major associated companies
accounted for using the equity method of accounting are those entities forming Alcoa World Alumina and Chemicals (AWAC) which prepares its financial statements in U.S. dollars in accordance with US GAAP. However, one of those entities is an
Australian based company which Alumina accounts for using its Australian domestic financial statements. The net income and shareholders equity concerned have been adjusted to conform to US GAAP.

Effective 1 January 2002, Alumina adopted APB 18, The Equity Method of Accounting for Investments in Common Stock for existing goodwill
assets, resulting in a cumulative effect gain write off of negative goodwill amounting to $3.7 million.

The principal differences between
A-IFRS and US GAAP that affect Aluminas net income for associates, as well as its shareholders equity, either directly or through its share of associates on a continuing basis relate to the treatment of the following items:



| |  |  | Fair Value Of Accounting For Derivatives  This difference relates to embedded derivatives. Under US GAAP, some embedded derivatives are grandfathered and
are not fair valued and as a result have no profit impact. Under A-IFRS, embedded derivatives are measured at fair value with changes in fair value recognised in the income statement;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Goodwill And Amortization  Under US GAAP, goodwill and other intangibles with indefinite useful lives are not amortized but under A-IFRS are tested for
impairment annually or more frequently if events or changes in circumstances indicate that it may be impaired, and is carried at cost less accumulated impairment losses. This is consistent with A-IFRS from date of transition to A-IFRS (January 1,
2004). Accumulated amortization recognized to January 1, 2004 under previous AGAAP remains a reconciling difference to US GAAP;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Pension Liabilities/Assets  US GAAP differs from A-IFRS in a number of respects. The most significant difference is that under A-IFRS, an asset maximum
exists for pension funds with a net asset surplus. No asset maximum exists under US GAAP;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Asset Retirement Obligations (AROs)  Under A-IFRS, AROs are required where there is a legal or constructive obligation as a result of a past event
and it is probable that there will be outflows of economic benefits to settle the obligation. Under US GAAP, constructive obligations are not recognized but are only required where there is a legal obligation, an agreement or a promise has been
made to a third party, the method of settlement is determinable and a settlement date is able to be estimated. The AROs recorded are in relation to refineries (Kwinana, Pinjarra, Wagerup, Pt Comfort, Suralco, San Ciprian, Jamaica and Abalco), and
smelters (Point Henry and Portland).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Share based payments
|--- | --------------------

Under A-IFRS, the Group is
required to recognize an expense for those performance share rights that were issued to employees under the Alumina Employee Share Plan and not vested at year end.

Previous US GAAP guidance (FAS 123), permitted the application of APB 25 Accounting for Stock Issued to Employees which measured compensation expense using an intrinsic value model, which resulted in
a GAAP difference. Effective January 1, 2006, FAS 123 was revised, effectively eliminating the alternative of using APB 25. The new standard FAS 123R, resulted in A-IFRS and US GAAP being largely aligned in respect of accounting for share
based payments. AWAC elected the modified prospective application method for adoption, and prior financial statements have not been restated.



|(c) | Cash flow
|--- | ---------

There are no A-IFRS to US GAAP
reconciling items for the cash flow statement in either the current or prior year.



|(d) | Income tax
|--- | ----------

Under A-IFRS, deferred taxes are
provided for using the liability method on a similar basis to FAS 109, therefore there has been no adjustment to the method by which income taxes have been calculated. Under US GAAP, the recognition and carry forward of future income tax
benefits differs from A-IFRS in the following areas:



| |  |  | Tax assets and liabilities relating to temporary (timing) differences are all classed as non-current under A-IFRS. Under US GAAP the future income tax benefits
and liabilities would be required to be allocated in the balance sheet between current and non-current items. This allocation would not have a significant effect. Refer also to Note 7.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tax assets relating to tax losses are not brought to account under A-IFRS unless their ultimate realization is probable. Under US GAAP, tax assets relating to
tax losses are all brought to account and a valuation allowance raised against the asset if it is more likely than not that some portion or all of the deferred tax asset will not be realized.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under A-IFRS, a deferred tax asset shall be recognized for the carry forward of unused tax losses and unused tax credits to the extent that it is probable
that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized.

|32. | RECONCILIATION TO US GAAP (continued)
|--- | -------------------------------------



|(e) | Business combinations
|--- | ---------------------

Under A-IFRS, amortization
of goodwill is prohibited, and replaced by impairment testing performed at least annually. Previously (up to date of transition to A-IFRS), goodwill was amortized on a straight line basis over 20 years. On transition to A-IFRS amortization of
goodwill previously recognised under AGAAP to January 1 2004 was reversed. Accumulated amortization to January 1 2004 remains a difference between A-IFRS and USGAAP.

|33. | RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
|--- | ----------------------------------------------

The
Financial Accounting Standards Board (FASB) has issued certain Statements of Financial Accounting Standards (SFAS) which are not effective with respect to the fiscal years presented in the financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, (SFAS 157). SFAS 157 defines fair value, establishes a
framework for measuring fair value in generally accepted principles, and expands disclosures about fair value measurements. The provisions of this standard apply to other accounting pronouncements that require or permit fair value measurements. SFAS
157 becomes effective for Alumina on January 1, 2008. Upon adoption, the provisions of SFAS 157 are to be applied prospectively with limited exceptions. The adoption of SFAS 157 is not expected to have a material impact on Alumina
Limiteds financial statements.

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes  an Interpretation of FASB Statement No. 109,(FIN 48). FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions
that it has taken or expects to take on a tax return. On January 17, 2007, the FASB affirmed its previous decision to make FIN 48 effective for fiscal years beginning after December 15, 2006. Accordingly, FIN 48 is effective for Alumina on
January 1, 2007. The adoption of FIN 48 is not expected to have a material impact on Alumina Limiteds financial statements.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Alumina Limited

We
have completed an integrated audit of Alumina Limited and its subsidiaries, ( Group) 2006 consolidated financial statements and of its internal control over financial reporting as of December 31, 2006 and audits of its 2005
and 2004 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) (the PCAOB). Our opinions, based on our audits, are presented below.

Consolidated financial statements and financial statement schedule

In our opinion, the accompanying consolidated balance sheets and the related consolidated income statements, statements of cash flows and statements of changes in equity present fairly, in all material respects, the financial position of
the Group at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with International Financial Reporting Standards as adopted
in Australia (A-IFRS). In addition, in our opinion, the financial statement schedule included herein presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial
statements. These financial statements and the financial statement schedule are the responsibility of the Groups management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits
of these statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of
financial statements includes 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. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1A, in 2005, the Company has
elected to apply the exemption from restatement of comparatives for AASB 132 Financial Instruments: Disclosures and Presentation and AASB 139 Financial Instruments: Recognition and Measurement, and therefore continues to apply Australian GAAP rules
to derivatives, financial assets and financial liabilities and hedging relationships for 2004.

A-IFRS vary in certain significant respects from accounting
principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 32 to the consolidated financial statements.

Internal control over financial reporting

Also, in our opinion,
managements assessment, included in Managements Annual Report on Internal Control Over Financial Reporting appearing under Item 15, that the Group maintained effective internal control over financial reporting as of
December 31, 2006 based on criteria established in Internal Control  Integrated Frameworkissued by the Committee of Sponsoring organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on
those criteria. Furthermore, in our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control  Integrated
Framework issued by the COSO. The Groups management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our
responsibility is to express opinions on managements assessment and on the effectiveness of the Groups internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in
accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit
of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal
control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

Report of Independent Registered Public Accounting Firm (continued)

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation
of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorisations of management and directors of the company; and
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

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

Report of Independent Registered Public Accounting Firm

To the Members of the Strategic Council of

Alcoa World Alumina and Chemicals
(AWAC)

In our opinion, the accompanying combined balance sheets and the related combined statements of income, members equity and cash
flows present fairly, in all material respects, the financial position of Alcoa World Alumina and Chemicals at December 31, 2006 and 2005, and the results of their operations and their cash flows for the years then ended in conformity with
accounting principles generally accepted in the United States of America. These financial statements are the responsibility of AWACs management. Our responsibility is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As
discussed in Note A to the combined financial statements, AWAC changed its method of accounting for their benefit plans, stock-based compensation and mine stripping costs in 2006. As discussed in Note C to the combined financial statements,
AWAC changed its method of accounting for conditional asset retirement obligations in 2005.

|A. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Basis of Presentation

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 estimates and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the
financial statements. They also may affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Principles of Combination

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 Ltd and
Alumina Limited, resulting in existing WMC Shareholders receiving shares in a new listed entity WMC Resources Ltd, which holds the non-AWAC businesses. Alumina Limiteds (formerly WMC) only significant asset is the 40%
interest in AWAC.

The amounts presented within AWAC are stated at historical cost. All transactions between entities included in the
combined financial statements have been eliminated.

AWAC also evaluates consolidation of entities under Financial Accounting Standards
Board (FASB) Interpretation No. 46, Consolidation of Variable Interest Entities (FIN 46). FIN 46 requires management to evaluate whether an entity or interest is a variable interest entity and whether
Alcoa is the primary beneficiary. Consolidation is required if both of these criteria are met. AWAC does not have any variable interest entities requiring consolidation.

Investments in other entities are accounted for principally on the equity basis.

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 a substantial 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.
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, averaging 33 years for structures and approximately 16 years for machinery and equipment as useful lives range between five and 25 years. 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. Depletion related to mineral reserves is recorded using the units of
production method. 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 analysis.

Goodwill and Other Intangibles

Goodwill and intangibles with indefinite useful lives are not amortized. Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Goodwill and indefinite-lived intangibles are
tested annually for impairment and whenever events or circumstances change, such as a significant adverse change in business climate or the decision to sell a business, that would make it more likely than not that an impairment may have occurred. If
the carrying value of an indefinite-lived intangible asset exceeds its fair values, an impairment loss is recognized. The evaluation of goodwill impairment involves comparing the current fair value of the reporting unit to the recorded value,
including goodwill. AWAC uses a discounted cash flow model (DCF model) to determine the current fair value of the reporting unit. 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 volume and prices, costs to produce, and working capital changes. Management considers historical experience and all available information at the time the fair values of its
reporting units are estimated. However, actual fair values that could be realized in an actual transaction may differ from those used to evaluate impairment of goodwill. If the DCF model produces a fair value less than the carrying amount of the
reporting unit, an impairment loss is measured by comparing the implied fair value of goodwill to the carrying amount of the goodwill. See Note F for additional information.

Computer software costs consist primarily of software costs associated with an enterprise business solution (EBS). EBS costs are amortized
over 10 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 through 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 G for additional information.

On certain accounts payable contracts, AWAC has the option to
elect payment terms which are extended beyond payment terms which are normal and customary in the industry. These arrangements settle within one year and have a stipulated interest rate. Amounts outstanding under these arrangements have been
classified as short-term borrowings.

Revenue Recognition

AWAC recognizes revenue when title, ownership, and risk of loss pass to the customer.

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 is being amortized over the life of the contract based on the tonnage shipped.

Environmental Expenditures

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 elements of costs such as site investigations, consultant fees, feasibility studies, outside contractor, 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 periodically 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.

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 would also recognize an ARO
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 because the fair value of such potential retirement obligations cannot be reasonably estimated. 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. The perpetual nature of refineries and smelters, maintenance and upgrade programs, and other factors prevent a reasonable estimation to be made due to uncertainties
surrounding the ultimate settlement date. At the date a reasonable estimate 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. Such amounts may be material to the
combined financial statements in the period in which they are recorded.

Mine Development Costs

Costs incurred during the exploration/evaluation phases are expensed. This phase ends when we have determined that the mineral deposit can be mined and
processed economically.

Development phase costs are
capitalized and include costs to construct the mine, including overburden removal, roads, and land improvements. Costs incurred during the production phase are recognized in cost of products sold and include all costs to extract the minerals,
including post production overburden removal and amortization of any capitalized development costs.

Mine development costs, classified on
the combined balance sheet as other noncurrent assets and deferred charges, are generally deferred and amortized over the period during which the resources are extracted on a units of production basis. Applicable mine development costs are charged
to expense in the year any program is abandoned.

Capitalized mine development costs (along with all other property, plant and equipment)
are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of such assets (asset group) may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows
of the operations to which the assets (asset group) relates to the associated carrying value of the assets (asset group). The amount of the impairment loss to be recorded, if any, is calculated as the excess of the carrying value of the assets
(asset group) over their fair value, with fair value generally determined using a discounted cash flow analysis. See Note F for additional information.

Income Taxes

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

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 (LLC). 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 LLCs are recorded in the financial statements of the members and, thus, are not reflected in AWACs financial statements. See Note L for additional information.

Stock-Based Compensation

Certain
employees of AWAC receive stock options under Alcoas Long Term Incentive Stock Plan and AWAC receives charges for stock option exercises under this plan. Effective January 1, 2006, AWAC accounts for stock-based compensation in accordance
with the provisions of Statement of Financial Accounting Standards (SFAS) No. 123(R), Share-Based Payment. 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 following the date of grant. Prior to the adoption of SFAS No. 123(R), AWAC used the nominal vesting approach related to
retirement-eligible employees, in which the compensation expense is recognized ratably over the original vesting period. AWAC accounted for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion
No. 25, Accounting for Stock Issued to Employees.As part of AWACs stock-based compensation plan design, individuals that are retirement-eligible have a six-month requisite service period in the year of grant. Equity grants are
issued in early January each year. As a

result, a larger portion of expense
will be recognized in the first and second quarters of each year for these retirement-eligible employees. Compensation expense recorded in 2006 was $5.2 ($3.6 after tax). Of this amount, $1.5 pertains to acceleration of expense related to
retirement-eligible employees.

As of January 1, 2005, AWAC switched from the Black-Scholes pricing model to a lattice model to
estimate fair value at the grant date for future option grants. On December 31, 2005, Alcoa accelerated the vesting of 0.8 million unvested stock options granted to employees of AWAC in 2004 and on January 13, 2005. The 2004 and 2005
accelerated options had weighted average exercise prices of $35.60 and $29.54, respectively. The decision to accelerate the vesting of the 2004 and 2005 options was made primarily to avoid recognizing the related compensation expense in future
financial statements upon the adoption of SFAS No. 123(R). The accelerated vesting of the 2004 and 2005 stock options reduced AWACs after-tax stock option compensation expense in 2006 by approximately $2.0 and an insignificant amount in
2007.

An additional change has been made to the stock-based compensation program for 2006 grants. Plan participants can choose whether to
receive their award in the form of stock options, restricted stock units (stock awards), or a combination of both. This choice is made before the grant is issued and is irrevocable. This choice resulted in an increased stock award expense in
comparison to 2005.

SFAS No. 123(R) requires Alcoa to recognize compensation expense for stock-based compensation ratably over the
requisite service period based on the fair value of the grant. Determining the fair value of stock options at the grant date requires judgment including estimates for the average risk-free interest rate, expected volatility, expected exercise
behavior, expected dividend yield, and expected forfeitures. If any of these assumptions differ significantly from actual, stock-based compensation expense could be impacted.

Derivatives and Hedging

Derivatives
are held as part of a formally documented risk management program. All derivatives are held for purposes other than trading. 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, if any, are recorded in revenues or other income or expense in the current period. If the hedging
relationship ceases to be highly effective or it becomes probable that an expected transaction will no longer occur, future gains or losses on the derivative are recorded in other income or expense.

AWAC accounts for hedges of foreign currency exposures and certain forecasted transactions, principally purchases of natural gas and fuel oil, 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 fair values of these derivatives are recorded in accumulated
other comprehensive income and are reclassified to sales, cost of goods sold or other income 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 within three years. Assuming market rates remain constant with the rates at December 31, 2006, $34.2 of the $38.0 loss included in other comprehensive income is expected to be recognized in earnings over the next twelve months. See
Note Q for additional information regarding accumulated other comprehensive income.

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

Cash flows from financial instruments 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 Brazil,
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.

Recently Adopted Accounting Standards

AWAC adopted Financial Accounting Standards Board (FASB) Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations (FIN 47), effective December 31, 2005. See Note C for
additional information.

On January 1, 2006, AWAC adopted SFAS No. 123(R), Share-Based Payment, which requires the company
to recognize compensation expense for stock-based compensation based on the fair value of the share-based employee grants. SFAS No. 123(R) revises SFAS No. 123 Accounting for Stock-Based Compensation and supersedes Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations (APB 25). AWAC elected the modified prospective application method for adoption, and prior periods financial
statements have not been restated. See Note K for additional information.

On January 1, 2006 AWAC adopted EITF 04-6,
Accounting for Stripping Costs Incurred during Production in the Mining Industry (EITF 04-6). EITF 04-6 requires that stripping costs incurred during the production phase of a mine are to be accounted for as variable
production costs that should be included in the costs of the inventory produced (that is, extracted) during the period that the stripping costs are incurred. Upon adoption, AWAC recognized a cumulative effect adjustment in the opening balance of
retained earnings of $5.6, representing the reduction in the net book value of postproduction stripping costs of $8.6, offset by a related deferred tax liability of $3.

AWAC adopted (SFAS) No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an amendment of FASB Statements No. 87, 88, 106 and
132 (R), (SFAS 158), effective December 31, 2006. SFAS 158 requires an employer to recognize the funded status of each of its defined pension and postretirement benefit plans as a net asset or liability in its
statement of financial position with an offsetting amount in accumulated other comprehensive income, and to recognize changes in that funded status in the year in which changes occur through comprehensive income. The provisions of SFAS 158 are
to be applied on a prospective basis; therefore, prior periods presented are not restated. The adoption of SFAS 158 resulted in the following impacts: a reduction of $22.1 in existing prepaid pension costs and intangible assets, the reduction
of $47.0 in accrued pension and postretirement liabilities, and a pretax credit of $24.9 to other comprehensive income. See Note J for additional information.

Additionally, SFAS 158 requires an employer to measure the funded status of each of its plans as of the date of its year-end statement of financial position. The funded status of all of AWACs pension and
other postretirement benefit plans is currently measured as of December 31.

In September 2006, the Securities and Exchange
Commission issued Staff Accounting Bulletin No. 108 (SAB 108). SAB 108 was issued to provide interpretive guidance on how the effects of

the carryover or reversal of prior
year misstatements should be considered in quantifying a current year misstatement. The provisions of SAB 108 are effective for AWAC for its December 31, 2006 year-end. The adoption of SAB 108 did not have a material impact on
AWACs combined financial statements.

Recently Issued Accounting Standards

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, (SFAS 157). SFAS 157 defines fair value,
establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of this standard apply to other accounting pronouncements that require or permit fair
value measurements. SFAS 157 becomes effective for AWAC on January 1, 2008. Upon adoption, the provisions of SFAS 157 are to be applied prospectively with limited exceptions. The adoption of SFAS 157 is not expected to have a
material impact on AWACs combined financial statements.

In July 2006, the FASB issued FASB Interpretation No. 48,
Accounting for Uncertainty in Income Taxes  an Interpretation of FASB Statement No. 109, (FIN 48). FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in
its financial statements uncertain tax positions that it has taken or expects to take on a tax return. On January 17, 2007, the FASB affirmed its previous decision to make FIN 48 effective for fiscal years beginning after December 15,
2006. Accordingly, FIN 48 is effective for AWAC on January 1, 2007. Management has determined that the adoption of FIN 48 will not have a material impact on AWACs combined financial statements.

Reclassification

Certain amounts in
the previously issued financial statements were reclassified to conform to the 2006 amounts.



|B. | Nature of Operations
|-- | --------------------

In December 1994 and
January 1995, Alcoa and Alumina Limited entered into a multi-step transaction to restructure and combine the ownership of their respective worldwide bauxite, alumina and alumina-based chemicals businesses and investments into a group of
companies known collectively as AWAC. AWAC is owned 60% by Alcoa and 40% by Alumina Limited.

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 48% and 49% of AWACs respective 2006 and 2005 alumina production was sold to Alcoa. In
addition, Alcoa of Australia (AofA), the largest entity within AWAC, operates integrated aluminum facilities in Australia including mining, refining and smelting operations. Approximately 72% and 70% of AofAs 2006 and 2005 revenues
of $3,650.1 and $2,842.6, respectively, were derived from alumina, and the balance was derived principally from primary aluminum.

|C. | Asset Retirement Obligations
|-- | ----------------------------

AWAC adopted
FIN 47, effective December 31, 2005. FIN 47 clarifies the accounting for conditional asset retirement obligations (CAROs), as referenced in SFAS No. 143, Accounting for Asset Retirement Obligations(SFAS
No. 143). A CARO is a legal obligation to perform an asset retirement activity in which the obligation is unconditional, but uncertainty exists about the timing and (or) method of settlement, which may or may not be under the control of
AWAC, and which prevents the reasonable estimation of the fair value of the CARO. Upon adoption, AWAC recognized a cumulative effect adjustment of $0.2, consisting primarily of costs related to the restoration of a leased facility. Pro forma amounts
related to prior periods are not presented, as there is no impact on prior period financial statements.

In additional to the above CAROs,
AWAC has recorded the 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 potline disposal,
closure of bauxite residue areas, mine reclamation, and landfill closure. There have been no significant revisions to cash flow estimates for asset retirement obligations as of December 31, 2006.

The following table details the changes in the carrying amounts of AROs at December 31:

|G. | Short-Term Borrowings
|-- | ---------------------

In May 2001, Alcoa
entered into a loan agreement with AAC LLC whereby AAC LLC may borrow funds from Alcoa in various installments or draw downs. Each individual draw down has its own maturity not to exceed 60 days, and bears interest at the
rate for deposits in U.S. dollars as determined by the British Bankers Association on the day of the borrowing. The short-term borrowings between AAC LLC and Alcoa under this agreement were fully repaid during 2006 from

the capital contribution made on
October 31, 2006. See Note B for additional information. Outstanding amounts under this agreement were $76.1 at December 31, 2005.

During 2006, Abalco entered into a short-term note payable with a third-party bank bearing interest at 5.09%. Outstanding amounts for this agreement were $11.4 as of December 31, 2006. This amount will be repaid during 2007.

During 2006, AofA received advances from its joint venture partners in the Portland smelter. These advances are repayable upon demand.
These advances accrue interest at the Australian dollar official cash rate less five basis points. The rate was 6.20% at December 31, 2006. Amounts outstanding under this arrangement were $2.8 at December 31, 2006.

AWAC participates in computerized payable settlement arrangements with certain vendors and third-party intermediaries. As of December 31, 2006 and
2005, short-term borrowings included $89.5 and $36.5, respectively, of amounts that will be paid through the 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.
Imputed interest on the borrowings were $1.6 in 2006 and insignificant for reclassification to interest expense in 2005. See Note A for additional information.

Alumina Espanola has the option to enter into extended trade payable arrangements which are longer than normal customary terms. These arrangements have terms up to 180 days. The extended terms can be elected at a
rate of 3 month Libor + 1%. Outstanding amounts under these arrangements were $20.8 and $0 at December 31, 2006 and 2005, respectively.

During 2006, AWA LLC received advances from its joint venture partner in the Jamaica refinery. These advances are repayable upon demand. These advances accrue interest at the Cayman overnight deposit rate. The rate was 5.0% at
December 31, 2006. Amounts outstanding under this arrangement were $4.3 a December 31, 2006.



|H. | Related Party Transactions
|-- | --------------------------

AWAC is controlled by
its majority owner, Alcoa. AWAC receives related party sales revenues for alumina and chemical products sold to:



|      |  |      |         |      |   |        
|----- |  | ---- | ------- | ---- | - | -------
|      |  | 2006 |         | 2005
|Alcoa |  | $    | 2,055.0 |      | $ | 1,643.1
|Other |  |      | 24.1    |      |   | 27.1   
|      |  |      |         |      |   |        
|      |  | $    | 2,079.1 |      | $ | 1,670.2
|      |  |      |         |      |   |        

The terms for all transactions and agreements between related parties and AWAC are established by
negotiation between the parties.

Certain entities within AWAC have entered into contractual agreements with Alcoa for employee services
(principally related to employees of the U.S. operations), an administrative services agreement, a commodity and foreign exchange hedging agreement and an alumina sales agreement. Total costs incurred by AWAC for these agreements were approximately
$80.6 in

2006 and $77.9 in 2005. AWAC also has
a long-term bauxite purchase agreement with a partially-owned entity. Total purchases under this agreement were approximately $120.2 and $124.8 during 2006 and 2005, respectively.

In 2006 and 2005, AWAC was charged and paid $0.1 and $0.7, respectively for stock option exercises under Alcoas Long Term Stock Incentive Plan.
These amounts were reflected as a dividend paid to partners, net of a minimal tax benefit in 2006 and $0.3 in 2005. See Note A for additional information.



|I. | 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 $63.2 in 2006 and $51.2 in 2005. Under long-term leases,
minimum annual rentals are $48.2 in 2007, $43.0 in 2008, $43.6 in 2009, $39.9 in 2010, $32.2 in 2011 and a total of $59.9 for 2012 and thereafter.



|J. | 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.

On September 29, 2006, SFAS
No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans was issued. SFAS 158 requires, among other things, the recognition of the funded status of each defined pension benefit plan and other
postretirement benefit plan on the balance sheet. Each overfunded plan is recognized as an asset, and each underfunded plan is recognized as a liability. The initial impact of the standard due to unrecognized prior service costs or credits and net
actuarial gains or losses as well as subsequent changes in the funded status is recognized as a component of accumulated comprehensive loss in members equity. Additional minimum pension liabilities (AML) and related intangible
assets are no longer recognized upon adoption of the new standard.

Additionally, SFAS 158 requires an employer to measure the funded
status of its plans as of the date of its year-end statement of financial position. The funded status of AWACs pension and other postretirement benefits plans are currently measured as of December 31, 2006. AWAC adopted SFAS 158 as
of December 31, 2006. The table labeled Change due to the AML and adoption of SFAS 158 summarizes the impact at December 31, 2006. The total pretax credit to equity was $(24.9) of which $(28.5) relates to postretirement
benefits and $3.6 to pension benefits.

The aggregate projected benefit
obligation and fair value of plan assets for the pension plan with benefit obligations in excess of plan assets were both zero, as of December 31, 2006 and $490.3 and $458.1, respectively, as of December 31, 2005. The aggregate accumulated
benefit obligation and fair value of plan assets with accumulated benefit obligations in excess of plan assets were zero as of December 31, 2006 and 2005.

The unrecognized actuarial gain for postretirement benefit plans at December 31, 2006 of $31.5 primarily resulted from benefit payment projections exceeding actual payments. To the extent those gains exceed
certain thresholds, the excess will continue to be recognized. Generally, these amounts are amortized over the estimated future service of plan participants, which is 14 years.

Assumptions

Weighted average
assumptions used to determine benefit obligations at December 31:



|                              |  |      |   |  |      |

The basic goal underlying 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.

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.

Cash Flows

The minimum required cash contribution to the pension plans in 2007 are estimated to be $19.2.

|K. | Stock-Based Compensation
|-- | ------------------------

On January 1, 2006,
AWAC adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), Share-Based Payment, which requires the company to recognize compensation expense for stock-based compensation based on the grant date fair
value. Prior to January 1, 2006, AWAC accounted for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations.
AWAC has elected the modified prospective application method for adoption, and prior period financial statements have not been restated.

Stock options under AWACs stock-based compensation plans have been granted at not less than market prices on the dates of grant. Beginning in 2006, performance stock options were granted to certain individuals. The final number of
options granted is based on the outcome of AWACs annual return on capital results against the results of a comparator group of companies. However, an individual can earn a minimum number of options if AWACs return on capital meets or
exceeds its cost of capital. Stock option features based on date of original grant are as follows:

In addition to the stock options
described above, AWAC granted restricted stock units (stock awards) that vest in three years from the date of grant. Certain of these stock awards were granted with the same performance conditions described above for performance stock options.
Certain employees of AWAC receive stock options and stock awards under the 2004 Alcoa Stock Incentives Plan and AWAC receives charges for stock option exercises under this plan.

An additional change has been made to the stock-based compensation program for 2006 grants. Plan participants can choose whether to receive their award in
the form of stock options, restricted stock units (stock awards), or a combination of both. This choice is made before the grant is issued and is irrevocable. This choice resulted in an increased stock award expense in comparison to 2005.

The following table summarizes the total compensation expense recognized for all options and stock awards:

Prior to January 1, 2006, no stock-based compensation expense was recognized for stock
options. As a result of the implementation of SFAS No. 123(R), Alcoa recognized additional compensation expense of $0.7 pretax ($0.5 after tax) in 2006 pertaining to options. There were no stock-based compensation expenses capitalized in 2006
or 2005. Alcoas net income for 2005 would have been reduced to the pro forma amounts shown below if employee stock option compensation expense had been determined based on the fair value at the grant dates in accordance with SFAS No. 123
and SFAS No. 148, Accounting for Stock-Based Compensation - Transition and Disclosure an amendment of FASB Statement No. 123.

As of January 1, 2005, Alcoa
switched from the Black-Scholes pricing model to a lattice model to estimate fair value at the grant date for future option grants. The fair value of each option is estimated on the date of grant or subsequent reload using the lattice pricing model
with the following assumptions:



|                                       |  |      |           |   |      |   |           |

|Weighted average fair value per option |  |      |           |   |      |   |           |  
|Average risk-free interest rate        |  | $    | 5.98      |   |      | $ | 6.18      |  
|Expected dividend yield                |  |      | 4.42-4.43 | % |      |   | 2.65-4.20 | %
|Expected volatility                    |  |      | 2.0       | % |      |   | 1.8       | %
|Expected annual forfeiture rate        |  |      | 27-32     | % |      |   | 27-35     | %
|Expected exercise behavior             |  |      | 3         | % |      |   |          | %
|Expected life (years)                  |  |      | 23        | % |      |   | 32        | %
|                                       |  |      | 3.6       |   |      |   | 3.8       |  

The range of risk-free interest rates is based on a yield curve of interest rates at the time of
the grant based on the contractual life of the option. Expected dividend yield is based on a five-year average. Expected volatility is based on historical and implied volatilities over the term of the option. Alcoa utilizes historical option
exercise and forfeiture data to estimate expected annual pre and post vesting forfeitures. The expected exercise behavior assumption represents a weighted average exercise ratio of gains resulting from historical employee exercise behavior. The 2006
expected exercise behavior assumption is based on exercise patterns for grants issued from 2000 forward.

Beginning in January of 2004, in
addition to stock option awards, the company has granted stock awards and performance share awards. Both vest three years from the date of grant. Performance share awards are issued at target and the final award amount is determined at the end of
the performance period.

|M. | Derivatives and Other Financial Instruments
|-- | -------------------------------------------

The
carrying values and fair values of AWACs financial instruments at December 31 follow:



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

|Notes receivable          |  |               | 0.5   |           |   | 0.5           |  |           | 1.1   |  |   | 1.1  
|Short-term debt           |  |               | 132.1 |           |   | 132.1         |  |           | 113.9 |  |   | 113.9

The methods used to estimate the fair value of certain financial instruments follow:

Cash and Cash Equivalents and Short-Term Borrowings

The carrying amount approximates fair value because of the short maturity of the instruments. The short-term borrowings weighted average interest rate is 6.92% in 2006 and 4.66% in 2005.

Noncurrent Receivables

The fair
value of noncurrent receivables is based on anticipated cash flows which approximates carrying value.

Cash Flow Hedges

AWAC uses derivative financial instruments for purposes other than trading. Fair value gains (losses) of material hedging contracts at December 31
were:



|                                                        |  |      |       |   |      |   |     
|------------------------------------------------------- |  | ---- | ----- | - | ---- | - | ----
|                                                        |  | 2006 |       |   | 2005
|Other commodities, principally natural gas and fuel oil |  | $    | (38.0 | ) |      | $ | 66.2

Commodities

AWAC anticipates the continued requirement to purchase other commodities such as natural gas, and fuel oil for its operations. AWAC enters into futures and options contracts to reduce volatility in the price of these
commodities. These instruments are designated as cash flow hedges and extend through March 2008. The net fair value of the outstanding instruments are a liability of $38.0 and an asset of $66.2 at December 31, 2006 and 2005, respectively.

AWAC is exposed to credit loss in the event of nonperformance by counterparties on the above instruments. Although nonperformance is
possible, AWAC does not anticipate nonperformance by any of the 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.

For
further information on AWACs hedging and derivative activities, see Note A.

Noncash Items

There were no significant noncash items at December 31, 2006 or 2005.



|O. | Commitments and Contingencies
|-- | -----------------------------

Various lawsuits and
claims and proceedings 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 exist. Therefore, it is possible that results of operations or liquidity 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 materially adverse effect on the financial position, results of operations or liquidity 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.

In October 2004, AWAC agreed to acquire a 20% interest in a consortium formed to acquire the Dampier to Bunbury Natural Gas Pipeline
(DBNGP) in Western Australia exchange for an initial cash investment of $17.0, which was classified as an equity investment. AWAC has made additional contributions of $26.8 and $19.2 in 2006 and 2005, respectively and committed to invest
an additional $63.0 to be paid as the pipeline expands through 2009. The investment in DBNGP was made in order to secure a competitively priced long-term supply of power to AWACs refineries in Western Australia. In addition to its equity
ownership, AWAC has an agreement to purchase gas transmission services from the DBNGP with the ability to terminate the agreement at its discretion. AWACs maximum exposure to loss on the investment and related contract is approximately $340.0.

In connection with the sale of Alcoa Specialty Chemicals (ASC) in 2004, AWAC entered into an agreement to supply ASC with
approximately 488,000 tons of alumina feedstock annually at a fixed price for 20 years. After three years and through the tenth year of the contract, the agreement provides for adjustments in pricing to the extent certain of AWACs costs
fluctuate outside of agreed upon thresholds.

AWAC has entered into other purchase
commitments for energy and raw materials which total $1,111.5 in 2007, $829.3 in 2008, $729.3 in 2009, $630.7 in 2010, $630.9 in 2011 and $2,904.2 thereafter.

During 2001, AWAC entered into a ten-year agreement with a vendor to provide process control hardware and software at a ten-year cost of approximately $146.0. At December 31, 2006, amounts remaining to be paid on
this agreement was approximately $120.0.

AWAC has standby letters of credit related to trade export activities. The total amount committed
under these letters of credit, which expire at various dates in 2007 through 2014 was $26.5 at December, 31, 2006.



|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 2006 and 2005 was $36.7 and $28.7, respectively, and reflects the most
probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Of the $36.7 reserve at December 31, 2006, $30.8 is classified as current on the combined balance sheet.



|Q. | Restructuring and Other Charges

Restructuring and
other charges were comprised of the following at December 31:

Report of Independent Registered Public Accounting Firm

To the Members of the Strategic Council of

Alcoa World Alumina and
Chemicals (AWAC)

In our opinion, the accompanying combined balance sheets and the related combined statements of income, comprehensive income,
members equity and cash flows present fairly, in all material respects, the financial position of Alcoa World Alumina and Chemicals at December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the
two years in the period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of AWACs management. Our responsibility is to
express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes 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. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note D to the combined financial statements, AWAC changed its method of accounting for conditional asset retirement obligations in
2005.

|A. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Basis of Presentation

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 estimates and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the
financial statements. They also may affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Principles of Combination

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. Investments in other entities are accounted for principally on the equity basis.

Effective December 11,
2002, WMC shareholders voted to create two entities, WMC Resources Ltd and Alumina Limited, resulting in existing WMC Shareholders receiving shares in a new listed entity WMC Resources Ltd, which holds the non-AWAC businesses. Alumina
Limiteds (formerly WMC) only significant asset is the 40% interest in AWAC.

The amounts presented within AWAC are stated
at historical cost. All transactions between entities included in the combined financial statements have been eliminated.

Effective
December 31, 2004, AWAC adopted Financial Accounting Standards Board (FASB) Interpretation No. 46 (FIN46), Consolidation of Variable Interest Entities.FIN46 addresses consolidation and disclosure by business
enterprises of variable interest entities. This standard has no impact on AWACs financial statements.

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 a substantial 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.
See Note E 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, averaging 33 years for structures and between 5 and 25 years for machinery and equipment. 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. Depletion related to mineral reserves is recorded using the units or production method. See Note F for additional information.

(dollars in millions)

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 generally determined using a discounted cash flow analysis.

Goodwill and Other Intangibles

Goodwill and intangibles with indefinite useful lives are not amortized. Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited, with a weighted average useful life of 10
years. Goodwill and indefinite-lived intangibles are tested annually for impairment and whenever events or circumstances change, such as a significant adverse change in business climate or the decision to sell a business, that would make it more
likely than not that an impairment may have occurred. If the carrying value of goodwill or an indefinite-lived intangible asset exceeds its fair values, an impairment loss is recognized. The evaluation of impairment involves comparing the current
fair value of the business to the recorded value, including goodwill. AWAC uses a discounted cash flow model (DCF model) to determine the current fair value of the business. 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 volume and prices, costs to produce, and working capital changes. Management considers historical experience and all available
information at the time the fair values of its reporting units are estimated. However, actual fair values that could be realized in an actual transaction may differ from those used to evaluate impairment of goodwill. See Note G for additional
information.

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 through 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.

Long-Term Debt

Long-term debt consists of mortgages that mature over time and amounts owed to the Government of Jamaica related to its 50% ownership in Jamalco. Jamalco
is a joint venture between Alcoa Minerals of Jamaica, L.L.C. and Clarendon Alumina Production Ltd, a wholly owned subsidiary of the Government of Jamaica.

Revenue Recognition

AWAC recognizes revenue when title, ownership, and risk of loss pass to the
customer.

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. A
prepayment of $240.0 related to an agreement with a third party customer is being amortized over the life of the contract based on the tonnage shipped.

Environmental Expenditures

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 elements of costs such as site investigations, consultant fees, feasibility studies, outside contractor, 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 periodically 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.

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 would also recognize an ARO
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 D for additional information.

Mine Development Costs

Mine
development costs, classified on the combined balance sheet as other noncurrent assets and deferred charges, are generally deferred and amortized over the period during which the resources are extracted on a units of production basis. Applicable
mine development costs are charged to expense in the year any program is abandoned. See Note G for additional information.

Income
Taxes

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

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 limited liability companies (LLC). 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 LLCs are recorded in the financial statements of the members and, thus, are not
reflected in AWACs financial statements. See Note L for additional information.

Stock-Based Compensation

Certain employees of AWAC receive stock options under Alcoas Long Term Incentive Stock Plan and AWAC receives charges for stock option exercises
under this plan. AWAC accounts for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees and related interpretations using the intrinsic value
method which resulted in no compensation costs for options granted. Net income would have been reduced to the pro forma amounts shown below if compensation cost had been determined based on the fair value at the grant dates in accordance with
Statement of Financial Accounting Standards (SFAS) Nos. 123 and 148, Accounting for Stock Based Compensation(SFAS Nos. 123 and 148).



|                                                                           |  |      |       |      |   |

|Less: Compensation cost determined under the fair value method, net of tax |  |      | 4.8   |      |   | 2.4  
|                                                                           |  |      |       |      |   |      
|Pro forma net income                                                       |  | $    | 639.8 |      | $ | 586.1
|                                                                           |  |      |       |      |   |      

Upon adoption of SFAS No. 123 (revised 2004), Share-Based Payment (SFAS
No. 123 (R)), the company is required to recognize compensation expense for those employees using the nonsubstantive vesting period approach, in which the compensation expense is recognized ratably over the requisite service period
following the date of grant. The impact of this change on the attribution period would not have had a material impact on the results of operations for the periods presented herein.

On December 31, 2005, AWAC accelerated the vesting of 0.8 million unvested stock options granted to employees in 2004 and on January 13,
2005. The 2004 and 2005 accelerated options have weighted average exercise prices of $35.60 and $29.54, respectively. The decision to accelerate vesting of the 2004 and 2005 options was made primarily to avoid recognizing the related compensation
cost in future financial statements upon adoption of SFAS No. 123 (R), which AWAC will adopt on January 1, 2006 when it is required. The accelerated vesting of the 2004 and 2005 stock options will reduce AWACs after-tax stock
option compensation expense in 2006 and 2007 by $2.1.

In addition to stock option awards described above, beginning in 2004 the company
granted stock awards and performance share awards that vest in three years from the grant date. Compensation expense is calculated based on the fair value at the grant dates, and the after tax expense recognized on these awards in 2005 and 2004 were
$1.2 and $0.7, respectively.

(dollars in millions)

In anticipation of the
adoption of SFAS No. 123 (R), AWAC switched from the Black-Scholes pricing model to a lattice model to estimate fair value at grant date for options granted in 2005. The financial impact of this change is not material. AWAC will begin
expensing stock options as it is required, which is currently in the first quarter of 2006, using the modified prospective application.

The
fair value of each option is estimated on the date of grant or subsequent reload using the lattice or Black-Scholes pricing model with the following assumptions:



|                                |  |          |   |  |      |  
|------------------------------- |  | -------- | - |  | ---- | -
|                                |  | 2005     |   |  | 2004 |  
|Average risk-free interest rate |  | 2.65-4.2 | % |  | 2.1  | %
|Expected dividend yield         |  | 1.8      | % |  | 1.6  | %
|Expected volatility             |  | 27-35    | % |  | 32.0 | %
|                                |  |         
|Expected life (years)           |  |          |   |  |      |  
|New option grants               |  | 3.8      |   |  | 3.0  |  
|Reload option grants            |  |         |   |  | 3.0  |  

The weighted average fair value per option granted was $6.18 in 2005 and $7.72 in 2004.

Derivatives and Hedging

Derivatives are held as part of a formally documented risk management program. All derivatives are straightforward and are held for purposes other than trading. 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, if any, are recorded in revenues or other
income or expense in the current period. If the hedging relationship ceases to be highly effective or it becomes probable that an expected transaction will no longer occur, future gains or losses on the derivative are recorded in other income or
expense.

AWAC accounts for hedges of foreign currency exposures and certain forecasted transactions, principally purchases of natural gas
and fuel oil, 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 fair values of these derivatives are
recorded in other comprehensive income and are reclassified to sales, cost of goods sold or other income 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 within three years. Assuming market rates remain constant with the rates at December 31, 2005, $56.8 of the $66.2 gain included in other comprehensive income is expected to be recognized in earnings over the next twelve
months. See Note Q for additional information regarding accumulated other comprehensive income.

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

Cash flows from financial instruments are recognized in the combined
statement of cash flows in a manner consistent with the underlying transactions. See Note M for additional information.

Recently Adopted Accounting Standards

AWAC adopted Financial Accounting Standards Board (FASB) Interpretation No. 47, Accounting for Conditional Asset Retirement
Obligations (FIN 47), effective December 31, 2005. See Note D for additional information.

Recently
Issued Accounting Standards

SFAS No. 123 (R), Share-Based Payment(SFAS No. 123),was issued
in December 2004. This standard requires companies to measure and recognize the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value. AWAC will begin expensing stock options as it
is required, which is the first quarter of 2006, using the modified prospective approach. In addition, the company is required to reflect compensation expense for these individuals using the nonsubstantive vesting period approach, in which the
compensation expense is recognized ratably over the requisite service period following the date of grant.

SFAS No. 154, Accounting
for Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3(SFAS No. 154), was issued in June 2005. SFAS No. 154 requires retrospective application to financial statements
of prior periods for changes in accounting principle that are not adopted prospectively. This statement is effective January 1, 2006. This standard has no impact on AWACs financial statements.

SFAS No. 153, Exchanges of Nonmonetary Assets  an amendment of APB Opinion No. 29 (SFAS No. 153), was issued in
December 2004. This standard eliminates the exception for nonmonetary exchanges of similar productive assets to be measured based on the fair value of the assets exchanged and replaces it with a general exception for exchanges of nonmonetary
assets that do not have commercial substance. This standard is effective January 1, 2006. This standard has no impact on AWACs financial statements.

In 2005, the FASB issued EITF 04-6, Accounting for Stripping Costs Incurred during Production in the Mining Industry (EITF 04-6). EITF 04-6 requires that stripping costs incurred during the
production phase of a mine are to be accounted for as variable production costs that should be included in the costs of the inventory produced (that is, extracted) during the period that the stripping costs are incurred. EITF 04-6 is effective for
the first reporting period in fiscal years beginning after December 15, 2005. AWAC is currently evaluating the impact of this statement on the company.

Reclassification

Certain amounts in the previously issued financial statements were reclassified to
conform to the 2005 presentations.

|B. | Nature of Operations
|-- | --------------------

In December 1994 and
January 1995, Alcoa and Alumina Limited entered into a multi-step transaction to restructure and combine the ownership of their respective worldwide bauxite, alumina and alumina-based chemicals businesses and investments into a group of
companies known collectively as AWAC. AWAC is owned 60% by Alcoa and 40% by Alumina Limited.

Primarily all bauxite mined by AWAC entities
is refined into alumina by AWAC through a chemical process. The alumina is then further processed into alumina-based chemicals (see Note C) or is sold to customers to be smelted into primary aluminum. Approximately 49% and 54% of AWACs
respective 2005 and 2004 alumina production was sold to Alcoa. In addition, Alcoa of Australia (AofA), the largest entity within AWAC, operates integrated aluminum facilities in Australia including mining, refining and smelting
operations. Approximately 70% and 77% of AofAs 2005 and 2004 revenues of $2,842.6 and $2,194.3, respectively, were derived from alumina, and the balance was derived principally from primary aluminum.

AWAC consists of the following entities within the noted worldwide markets:



| | 1. | Two LLCs, which hold all of Alcoas and Alumina Limiteds bauxite, alumina and industrial chemicals operations in Guinea, India, Japan, China and the U.S.; all of
Alcoas interest in the bauxite and alumina operations in Jamaica and the majority of Alcoas bauxite and alumina shipping operations. In February 2004, the industrial chemicals operations in India, Japan, China, and the U.S. were
sold. See Note C for additional information.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Alcoas and Alumina Limiteds interest in AofA, including its aluminum smelting operations and Alumina Espanola S.A., an alumina-based chemicals business located in Spain.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | All of Alcoas and Alumina Limiteds interest in Alcoa Chemie GmbH and Alcoa Chemie Nederland, which represent Alcoas and Alumina Limiteds alumina-based
chemicals businesses located in Germany and the Netherlands. These facilities were sold by Alcoa and Alumina Limited in February 2004. See Note C for additional information.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | Abalco, S.A. (Abalco), an entity formed in Brazil to hold 35% of Alcoa Aluminios (Aluminio) interest in the Alumar alumina refinery
(Alumar) and 35% of Aluminios interest in Mineracao Rio do Norte S.A. (MRN), a bauxite mine that supplies bauxite to the Alumar refinery. The 35% interest is the estimated capacity necessary to fulfill Aluminios
export alumina sales.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | Effective December 30, 2004, Alcoa sold 40% of its interest in the Juruti bauxite project in Brazil to Alumina Limited. In exchange, Alumina Limited contributed to AWAC $33.3
in cash, $2.2 in net assets and $6.7 in assumed debt. The $33.3 was subsequently distributed to Alcoa. Alcoa contributed to AWAC $3.3 in net assets and $9.3 in debt. In January 2005, Alcoa and Alumina Limited together contributed cash of $16.5
which was used to repay the outstanding debt. AWACs interest in the Juruti bauxite project is held by the following entities, Omnia Minerios, Mineracao Sao Jorge Ltda, and Matapu Sociedade De Mineracao Ltda, which have been included in
these financial statements, as of the effective date of this transaction.

| | 6. | On June 28, 2004, AWAC increased its ownership stake in Halco Mining, Inc. (Halco) from 43% to 45%. AWAC paid $5.9 for the additional 2% interest in Halco which is
accounted for as an equity investment in the combined balance sheet.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7. | On December 23, 2005, AofA exercised its pre-emptive rights to acquire minority partner AngloGolds equity position in the Cape Bougainville and Mitchell Plateau joint
ventures in Western Australia for $1.6, which is accounted for as an equity investment in the combined balance sheet.

|C. | Assets Held for Sale
|-- | --------------------

In February 2004, Alcoa
Specialty Chemicals (ASC) was sold to two private equity firms led by Rhone Capital LLC for an enterprise value of $342.0, which included the assumption of debt and other unfunded obligations. As of the date of the transaction, the
shares of Alcoa Chemie Nederland (CAN), and Alcoa Chemie GmbH (ACG) were owned by Alcoa Automotive GmbH (Automotive), Alcoa Europe Holding, BV (AEH) and an affiliate of Alumina Limited, Westminer
International Holdings Limited (Westminer). The proceeds and the gain on the sale of ACN and ACG have not been reflected in the AWAC financial statements because Automotive, AEH and Westminer are not components of AWAC as defined in the
Formation Agreement. The net assets of these entities were reflected as contributions to Automotive, AEH and Westminer who then sold their respective interests directly to Rhone Capital LLC. However, AWAC received cash of $120.4 and recognized a
pre-tax loss of approximately $35.8 on the sale of the components of ASC that it owned directly. The loss is included in restructuring and other charges in the combined statement of income, comprehensive income and members equity. The
reduction in net assets associated with the contribution of ACN and ACG has been reflected as a distribution of members equity of $61.3.

There were no assets or liabilities held for sale at December 31, 2005 or 2004.

|D. | Asset Retirement Obligations
|-- | ----------------------------

AWAC adopted FIN 47,
effective December 31, 2005. FIN 47 clarifies the accounting for conditional asset retirement obligations (CAROs), as referenced in SFAS No. 143, Accounting for Asset Retirement Obligations(SFAS
No. 143). A CARO is a legal obligation to perform an asset retirement activity in which the obligation is unconditional, but uncertainty exists about the timing and (or) method of settlement, which may or may not be under the control of
AWAC, and which prevents the reasonable estimation of the fair value of the CARO. Upon adoption, AWAC recognized a cumulative effect adjustment of $0.2, consisting primarily of costs related to the restoration of a leased facility. Pro forma amounts
related to 2004 are not presented, as there is no impact on prior period financial statements.

Historically, AWAC has either operated
locations or sold them and in certain circumstances, has curtailed them for possible future use while continuing with ongoing security, utility and other maintenance costs as deemed necessary. In the event of decision to permanently shutdown and
(or) demolish a facility, AWAC would record an ARO for the removal, treatment, transportation, storage and (or) disposal of various regulated assets and hazardous materials such as asbestos, underground and aboveground storage tanks, PCBs, various
process residuals, solid wastes, electronic equipment waste and various other materials.

AROs have not been recorded in the financial
statements for any AWAC operating location  other than those with specific legal obligations for spent pot lining disposal, closure of bauxite residue areas, mine reclamation, landfill closure and specific lease restoration requirements 
because the fair value of such potential retirement obligations cannot be measured as the settlement dates for these operating locations cannot be estimated. Such amounts may be material to the financial statements in the period in which they are
recorded.

Effective January 1, 2003, Alcoa adopted SFAS No. 143. The cumulative effect adjustment recognized upon adoption of
this standard was a gain of $15.7. The following table details the changes in the carrying amounts of AROs at December 31:



|                             |  |      |      |   |      |   |      |

(dollars in millions)



|H. | Short-Term Borrowings
|-- | ---------------------

In May 2001, Alcoa
entered into a loan agreement with AAC LLC whereby AAC LLC may borrow funds from Alcoa in various installments or draw downs. Each individual draw down has its own maturity not to exceed 60 days, and bears interest at the
rate for deposits in U.S. dollars as determined by the British Bankers Association on the day of the borrowing. Outstanding amounts for this agreement were $76.1 and $58.5 at December 31, 2005 and 2004, respectively.

Other amounts due to Alcoa, classified as short-term borrowings, totaled $0.2 and $25.7 as of December 31, 2005 and 2004, respectively. A portion of
the 2004 balance was contributed to AWAC by Alcoa and Alumina Limited in the amount of $12.0. These amounts were repaid during January 2005. See Notes B and I for additional information.

AWAC participates in computerized payable settlement arrangements with certain vendors and third-party intermediaries. As of December 31, 2005 and
2004, short-term borrowings included $36.5 and $21.4, respectively, of amounts that will be paid through the 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.
Imputed interest on the borrowings in 2004 was insignificant for reclassification to interest expense. See Note A for additional information.



|I. | Related Party Transactions
|-- | --------------------------

AWAC is controlled by
its majority owner, Alcoa. AWAC receives related party sales revenues for alumina and chemical products sold to:



|      |  |      |         |      |   |        
|----- |  | ---- | ------- | ---- | - | -------
|      |  | 2005 |         | 2004
|Alcoa |  | $    | 1,643.1 |      | $ | 1,358.8
|Other |  |      | 27.1    |      |   | 37.6   
|      |  |      |         |      |   |        
|      |  | $    | 1,670.2 |      | $ | 1,396.4
|      |  |      |         |      |   |        

The terms for all transactions and agreements between related parties and AWAC are established by
negotiation between the parties.

Certain entities within AWAC have entered into contractual agreements with Alcoa for employee services
(principally related to employees of the U.S. operations), an administrative services agreement, a commodity and foreign exchange hedging agreement and an alumina sales agreement. Total costs incurred by AWAC for these agreements were approximately
$77.9 in 2005 and $78.2 in 2004. AWAC also has a long-term bauxite purchase agreement with a partially-owned entity. Total purchases under this agreement were approximately $124.8 and $108.1 during 2005 and 2004 respectively.

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 $51.2 in 2005 and $26.9 in 2004. Under long-term leases,

|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.

The projected benefit obligation for all defined benefit pension plans was $713.0 and $679.5 at
December 31, 2005 and 2004, respectively.

The accumulated benefit obligations for all defined benefit pension plans were $659.3 and
$630.0 at December 31, 2005 and 2004, respectively.

The aggregate projected benefit obligation and fair value of plan assets for the
pension plan with benefit obligations in excess of plan assets were $490.3 and $458.1, respectively, as of December 31, 2005 and $484.1 and $417.0, respectively, as of December 31, 2004. The aggregate accumulated benefit obligation and
fair value of plan assets with accumulated benefit obligations in excess of plan assets were $0.0 and $0.0, respectively, as of December 31, 2005 and $445.0 and $417.0, respectively, at December 31, 2004.

At December 31, 2005 and 2004, the long-term accrued pension benefits on the combined balance sheet were $0.0 and $2.3, respectively. The total
accrued benefit liability was $17.7 in 2005 and $26.7 in 2004, which included the current portion of the liability of $17.0 in 2005 and $24.4 in 2004 and the amounts attributed to joint venture partners of $0.7 in 2005. At December 31, 2005 and
2004, the prepaid pension benefit on the combined balance sheet was $135.3 and $70.4, respectively. The total prepaid benefit was $141.3 in 2005 and $70.4 in 2004, which included amounts attributed to joint venture partners of $6.0 in 2005.

The unrecognized net actuarial loss for pension benefits at December 31, 2005 of $67.8 has primarily resulted from the decline in
interest rates over the past four years. To the extent those losses exceed certain thresholds, the excess will continue to be recognized as prescribed under SFAS No. 87, Employers Accounting for Pensions. Generally, these amounts are
amortized over the estimated future service plan of participants, which is 10 years.

The benefit obligation for postretirement benefit
plans and net amount recognized were $45.2 and $68.0, respectively, as of December 31, 2005, and $38.0 and $67.8, respectively as of December 31, 2004. Of the net amount recognized, the long-term, current and amounts attributed to joint
venture partners were $63.6, $1.0, and $3.4, respectively as of December 31, 2005, and $64.4, $0.0 and $3.4, respectively, as of December 31, 2004.

Assumptions

Weighted average assumptions used to determine benefit obligations at December 31:



|                              |  |      |   |  |      |  
|----------------------------- |  | ---- | - |  | ---- | -
|                              |  | 2005 |   |  | 2004 |  
|Weighted average assumptions  |  |      |   |  |      |  
|Discount rate, at year end    |  | 5.00 | % |  | 4.79 | %
|Rate of compensation increase |  | 3.63 | % |  | 4.14 | %

The discount rate is based upon a yield available on government bonds with a term suitable to
match the liabilities.

Weighted average assumptions used to determine the net cost for years ended December 31:



|                                         |  |      |   |  |      |

|Weighted average assumptions             |  |      |   |  |      |  
|Discount rate, at year end               |  | 4.79 | % |  | 5.33 | %
|Expected long-term return on plan assets |  | 7.77 | % |  | 7.77 | %
|Rate of compensation increase            |  | 4.14 | % |  | 3.95 | %

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. On average, the actual return over the past 10 years has exceeded 8%.

Assumed health care cost trend rates at December 31:

|Health care cost trend rate assumed for next year           |  | 8.0  | % |  | 8.0  | %
|Rate that the cost trend rate gradually declines to         |  | 5.0  | % |  | 5.0  | %
|Year that the rate reaches the rate it is assumed to remain |  | 2010 |   |  | 2009 |  

The health care cost trend rate in the calculation of the 2004 benefit obligations was 8.0% from
2004 to 2005 and 8.0% from 2005 to 2006. Actual annual company health care trend experience over the past three year has ranged from 5.0% to 7.5%. The 8% trend rate will be maintained for 2006.

The basic goal underlying 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.

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 plans 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.

Cash Flows

The minimum required cash
contribution to the pension plan in 2006 is estimated to be $17.0.

The $6.6 loss carryforward that existed at December 31, 2004, related to Discovery Alumina, an
entity that was sold in February 2004 as part of the sale of the specialty chemicals business. The carryforward loss was retained by AWAC and not included in the sale. See Note C for additional information. During 2005, the entire loss
carryforward benefit was utilized by AWAC.

The methods used to estimate
the fair value of certain financial instruments follow:

Cash and Cash Equivalents and Short-Term Borrowings

The carrying amount approximates fair value because of the short maturity of the instruments. The short-term borrowings weighted average interest rate is
4.66% in 2005 and 1.05% in 2004.

Noncurrent Receivables

The fair value of noncurrent receivables is based on anticipated cash flows which approximates carrying value.

Long-Term Debt

The fair value is
based on interest rates that are currently available to AWAC for issuance of debt with similar terms and remaining maturities.

Cash
Flow Hedges

AWAC uses derivative financial instruments for purposes other than trading. Fair value gains of material hedging contracts
at December 31 were:



|                                                        |  |      |      |      |   |     
|------------------------------------------------------- |  | ---- | ---- | ---- | - | ----
|                                                        |  | 2005 |      | 2004
|Other commodities, principally natural gas and fuel oil |  | $    | 66.2 |      | $ | 14.6

Commodities

AWAC anticipates the continued requirement to purchase other commodities such as natural gas, and fuel oil for its operations. AWAC enters into futures and options contracts to reduce volatility in the price of these
commodities.

AWAC is exposed to credit loss in the event of nonperformance by counterparties on the above instruments. Although
nonperformance is possible, AWAC does not anticipate nonperformance by any of the 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.

For further information on AWACs hedging and derivative activities, see Note A.

Noncash Items

There were no significant noncash items at December 31, 2005.

Net assets sold as part of the ACN and ACG sale totaled $61.3 at February 29, 2004, the effective date of the sale. The net deficit contributed from
Alcoa and Alumina Limited as part of the sale of Alcoas interest in the Juruti bauxite project totaled $(11.0) at December 31, 2004. See Notes B and C for additional information.



|O. | Commitments and Contingencies
|-- | -----------------------------

Various lawsuits and
claims and proceedings 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 exist. Therefore, it is possible that results of operations or liquidity 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 materially adverse effect on the financial position or liquidity 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 pre-formation liabilities, such as existing environmental conditions, to the extent of their pre-formation ownership of the company or asset with which the liability is associated.

In October 2004, AWAC agreed to acquire a 20% interest in a consortium formed to acquire the Dampier to Bunbury Natural Gas Pipeline
(DBNGP) in Western Australia exchange for an initial cash investment of $17.0, which was classified as an equity investment. AWAC has made additional contributions of $19.2 in 2005 and committed to invest an additional $53.0 to be paid
as the pipeline expands through 2008. The investment in DBNGP was made in order to secure a competitively priced long-term supply of power to AWACs refineries in Western Australia. In addition to its equity ownership, AWAC has an agreement to
purchase gas transmission services from the DBNGP with the ability to terminate the agreement at its discretion. AWACs maximum exposure to loss on the investment and related contract is approximately $300.0.

In November 2005, AWA LLC and Alcan announced the signing of a Basic Agreement with the Government of Guinea that sets the framework for development
of a 1.5 million metric tons per year (mtpy) alumina refinery in Guinea, West Africa. This agreement sets out the items and framework for the alumina refinery project that were a part of the protocol signed in November 2004 and
a part of the memorandum of understanding (MOU) signed by AWA LLC and Alcan in May 2004. A detailed feasibility study for the refinery is expected to begin immediately after ratification of the Basic Agreement by the Guinean
National Assembly. The refinery, which would be operated by AWAC, would be expected to have an initial 1.5 million mtpy capacity, with expansion capability. Production is expected by early 2009.

In June 2005, AWACs
expansion plan was approved by Alcoas Board of Directors for the planned expansion of the Jamalco alumina refinery in Clarendon, Jamaica, which follows the agreement in principle signed by AWAC and the Government of Jamaica in
December 2004. Pending finalization of definitive documents, which is expected in due course, this project will add 1.5 million mtpy to Jamalco, more than doubling the refinerys capacity to at least 2.8 million mtpy. The
1.5 million mtpy expansion is expected to cost approximately $1.2 billion. As a result of this expansion, AWACs ownership in the refinery will increase from 50% to 77% with the Government of Jamaica continuing to own the remaining
minority interest.

In connection with the sale of ASC, AWAC entered into an agreement to supply ASC with approximately 488,000 tons of
alumina feedstock annually at a fixed price for 20 years. After three years and through the tenth year of the contract, the agreement provides for adjustments in pricing to the extent certain of AWACs costs fluctuate outside of agreed upon
thresholds.

AWAC has entered into other purchase commitments for energy and raw materials which total $587.1 in 2006, $470.1 in 2007,
$425.7 in 2008. $353.7 in 2009, $302.0 in 2010, and $3,094.1 thereafter.

During 2001, AWAC entered into a ten-year agreement with a vendor
to provide process control hardware and software at a ten-year cost of approximately $146.0. At December 31, 2005, amounts remaining to be paid on this agreement was approximately $104.7.



|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 2005 and 2004 was $28.7 and $24.4, respectively, and reflects the most
probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Of the $28.7 reserve at December 31, 2005, $24.0 million is classified as current on the combined balance sheet.
