Chairman’s Report

Creating a new company and direct investment in a world leader with a global network of bauxite, alumina, alumina chemicals and aluminium operations. 2002 was a year of enormous challenge and change. As WMC Limited and now as Alumina Limited we have a 40- Shareholder approval of WMC’s demerger in November 2002 plus-year history of successful partnership with Alcoa, which owns created two separately listed companies: Alumina Limited and the remaining 60 per cent of AWAC and manages its day-to- WMC Resources Ltd. This was a major achievement under onerous day operations. We will continue to build on these years of success conditions, made possible through the dedication of WMC’s to productively develop and grow AWAC to generate strong cash directors and staff. Their performance and commitment during flows, profits and dividends. this time was exceptional. The demerger separated WMC’s nickel, copper and fertilizer businesses from the alumina interests, in order to maximise value to shareholders for each of these assets. The intention was to create a clearer and more transparent valuation of the alumina business and allow shareholders to receive full value for their WMC interests in the event of a takeover offer. The two new resource companies provide shareholders with greater investment flexibility and choice and allow the two management teams, WMC Resources Ltd and Alumina Limited, to concentrate on their underlying business. The demerger was planned to occur in mid-2002. The timing was delayed to enable shareholders to benefit from Australian demerger tax relief legislation. Since the demerger we have created a new organisation, with The listing of Alumina Limited has been well received by the finan- its own distinct identity and objectives and organisational structure. cial markets and we are making progress against our initial goals.

Our intention is to fully distribute to shareholders, to the extent practicable, all fully franked dividends received from AWAC. Donald Morley Chairman Since AWAC was established in 1995, more than 100 per cent of net income has been distributed in dividends and capital returns to AWAC’s owners (annual dividends to Alumina averaged $226 million since 1995).

(CONTINUED)

Spain – San Ciprian refinery AWAC has 100 per cent ownership of the San Ciprian alumina refinery, which is located on the eastern coast of Spain. The refinery has an annual production capacity of 1.3 million tonnes having completed a 0.22 million tonne expansion in 2001. This expansion enabled alumina production to increase in 2002. Approximately 70 per cent of alumina produced at the San Ciprian refinery is sold to Alcoa's smelters in Spain. The balance of production is mainly sold as commodity-hydrate alumina to AWAC's chemicals business and to other chemical manufacturers in Europe.

Alumina-based chemicals AWAC is a major producer of alumina-based chemicals. The majority of chemical-grade alumina for AWAC’s chemical plants is sourced from the Point Comfort, San Ciprian and Kwinana Milling area – Pinjarra alumina refineries. AWAC sells industrial chemicals to customers in a broad spectrum of markets for use in refractories, ceramics, abrasives, polymer additives, chemicals processing and other speciality applications. AWAC also has interests in 17 alumina- based chemicals plants in Australia, the United States of America, the Netherlands, Germany, Spain, Japan, India and China.

Shipping AWAC owns and operates a shipping business that provides transportation services to AWAC’s alumina business and to third 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.

SECTION – 5. Growth and Strategy

‘These potential expansion opportunities exceed a total of three million tonnes of alumina capacity.’

AWAC’s growth is driven by a strategy of low-risk, high-return ups. Yet they can be expected to produce the same, if not better, brownfield expansion. This strategy allows AWAC to maintain its operating results. AWAC is currently expanding its operations at 25% share of global production capacity. the Jamalco refinery. Potential brownfield expansion opportunities exist at operations at Wagerup and Pinjarra, and in Suriname, AWAC is a significant global business with a history of strong profits and growth, delivered through a consistent business São Luis and a further expansion of Jamalco. These potential strategy. Key elements of the growth strategy are brownfield expansion opportunities exceed a total of three million tonnes expansion of existing operations and increasing capacity through of annual alumina capacity. This expansion capacity equates to operational improvements. approximately two years of recent growth in the global alumina market. Expansion of existing operations On 17 October 2002, AWAC announced that it had signed a Brownfield expansions typically require less than half the per unit letter of intent with BHP Billiton, its 45 per cent partner in a joint capital expenditure, and are of lower risk, than greenfield start- venture in Suriname, covering several issues, including:

Continuation of mining and refining of bauxite in eastern Suriname beyond the existing term of the current joint venture agreement (2006). Preparation for an approximate 12 per cent expansion of operations at the Paranam refining facility, to capture operating- cost efficiencies. Investigation of bauxite mining and refining opportunities in western Suriname over the next two years. Separately, AWAC will explore the feasibility of establishing hydroelectric power opportunities in western Suriname that can be used for future development needs.

Incremental growth AWAC has successfully pursued a strategy of achieving increm- ental growth in refinery capacity. Basically, a small annual increase through each site can prove just as profitable, and far less costly than investing in greenfield operations. This growth is achieved by a combination of de-bottlenecking operations and improved efficiencies. De-bottlenecking involves optimising a process plant through minor capital expenditure and procedural change.

Acquisitions AWAC has the expertise, borrowing capacity and track record to acquire under-performing assets and improve their relative cost position and profitability. In late 2002, as forecast in the Demerger Scheme Booklet, Alumina Limited contributed A$24 million to AWAC for the acquisition of a further 6 per cent interest in Halco (a bauxite mining asset in Guinea), as well as A$48.6 million to AWAC for the acquisition of a further 5 per cent interest in MRN (a bauxite mining asset in Brazil). These purchases result from the Alcoa merger with Reynolds Metals and the subsequent transfer of Reynolds’ bauxite assets to AWAC.

Other growth opportunities A decision by Alcoa and Chalco to proceed with the 50/50 joint venture with respect to Chalco’s bauxite alumina and aluminium facilities at Pingguo in China may be formalised in the second half of 2003. Any decision by AWAC on the acquisition of the Pingguo bauxite and alumina assets is still to be made and is subject to a successful conclusion to negotiations on the joint venture. The Pingguo alumina refinery is being expanded in 2003 to a capacity of 850,000 tonnes per annum. Alcoa acquired a greenfield bauxite deposit in Juruti, Brazil in 2000 as a result of its merging with Reynolds in 2000. Alumina Limited and Alcoa continue to have discussions on the Juruti deposit.

At balance date there were no partly paid shares (2001: 629,000) callable at the option of the holders, and which at balance date were considered dilutive for the purpose of the calculation of diluted earnings per share. The employee options issued during the year were not potentially dilutive as they can only be exercised one year after the date of issue. Options issued in previous financial years are considered dilutive.

NOTE 6 Consolidated DIVIDENDS Millions of dollars 2002 2001

Interim Dividend No. 46 of 5 cents fully franked at 30% per fully paid share declared 13 August 2002 and paid 10 September 2002 (2001: 16 cents fully franked at 30% per fully paid share declared 14 August 2001 and paid 6 September 2001). 55.6 176.8 Final Dividend No. 45 of 13 cents fully franked at 30% per fully paid share, paid on 15 May 2002 and recognised as a liability at 31 December 2001 but adjusted against retained profits at the beginning of the financial year on the change in accounting policy for providing for dividends (refer Note 2). 144.1 144.1 Special unfranked dividend of 73 cents distributed to effect the demerger (refer Note 1). 823.0 – 1,022.7 320.9 (a) For all dividends referred to above, the relevant proportion as determined in accordance with the WMC Employee Share Scheme was declared and paid in respect of partly paid shares issued thereunder. (b) Franking account Balance of franking account adjusted for franking credits which will arise from the payment of income tax provided for in these financial statements: Class ‘C’ (30%) franking credits 37.1 (124.3) The fully franked dividends received from Alcoa of Australia Limited (‘AofA’) in the financial year were: 261.8 314.0 Due to changes in the Australian Tax Legislation, the franking account is maintained on a tax paid basis from 1 July 2002. These changes required an adjustment to the company’s franking account balance at that date, being a decrease of $2.4m The franking account balance at 31 December 2001 as disclosed for comparative purposes has not been restated. The new Tax Consolidation Regime will, should the Alumina Limited Group decide to adopt the Regime, impact the franking account balances of the Company and wholly-owned Australian resident subsidiaries. The potential impact of the new Tax Consolidation Regime has not been taken into account in determining the balance of the Company’s franking account.

(c) Dividends not recognised at year end In addition to the above dividends, since year end the Directors have recommended the payment of a final dividend No. 47 of 13 cents fully franked at 30% per fully paid share, declared 26 February 2003 and payable on 8 April 2003. The aggregate amount of the proposed dividend expected to be paid out of retained profits at 31 December 2002, but not recognised as a liability at year end as a result of the change in accounting policy for providing for dividends (refer note 2) is $146.7 million.
