Addendum to Annual Report

BHP Billiton Limited 22 October 2002 BHP Billiton Limited is issuing this announcement to fulfil disclosure obligations arising from its secondary listing on the London Stock Exchange. The text of this release is identical to that issued by BHP Billiton Plc earlier. 22nd October 2002 US GAAP Supplementary Note - Revision BHP Billiton prepares financial statements to reflect the different accounting standards in operation in each of Australia and the United Kingdom, Australian GAAP and UK GAAP respectively. These statements remain unchanged. The Australian and UK GAAP statements are reconciled to US generally accepted accounting principles (US GAAP) in supplementary note disclosures contained in the Group's annual reports. In preparing the US GAAP reconciliation, a tax adjustment was reflected incorrectly, resulting in the estimated tax expense being inadvertently overstated. This had the effect of understating the US GAAP net income and disclosures shown in the supplementary note entitled 'US Generally Accepted Accounting Principles Disclosures' only. It does not alter any other aspect of the financial statements. We have revised the affected note. The Group's auditors have confirmed the revised supplementary note disclosures reflect the changes required and do not affect their unqualified audit opinions dated 9 September 2002. As a US Registrant, BHP Billiton is also required to file an annual report on Form 20-F with the US Securities & Exchange Commission. This report, which is due to be filed in December, will incorporate the revised note disclosure. A copy of the revised note for the BHP Billiton Limited and BHP Billiton Plc Reports is attached. Karen Wood Company Secretary Addendum to BHP Billiton Limited Annual Report 2002 - Combined Financial Statements Note 49 to the financial statements (appears in condensed form as Note 10 to the Concise Report)- US Generally Accepted Accounting Principles Disclosures - has been revised. This version supersedes that included in the BHP Billiton Limited Annual Report 2002 - Combined Financial Statements. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES The financial statements of the BHP Billiton Group are prepared in accordance with Australian Generally Accepted Accounting Principles (GAAP). The financial statements, analyses and reconciliations presented in this note represent the financial information which would be required if US GAAP had been applied instead of Australian GAAP. Certain additional disclosures that would normally accompany these disclosures were they being prepared in the context of a filing with the US Securities and Exchange Commission have been omitted. DLC merger On 29 June 2001, BHP Billiton Plc (formerly Billiton Plc) consummated the Dual Listed Companies ('DLC') merger with BHP Billiton Limited (formerly BHP Limited). A description of the DLC merger structure is provided in 'Dual Listed Companies Structure and Basis of Preparation of Financial Statements'. In accordance with Australian GAAP, the assets, liabilities and equity of the BHP Billiton Plc Group and of the BHP Billiton Limited Group are combined at their respective book values as at the date of consummation of the merger. Under US GAAP the DLC merger is accounted for as a purchase business combination with the BHP Billiton Limited Group acquiring the BHP Billiton Plc Group. The BHP Billiton Limited Group has been identified as the acquirer because of the majority ownership interest of BHP Billiton Limited shareholders in the DLC structure. Under US GAAP, the reconciliation of shareholders' equity includes the purchase adjustments required under US GAAP to recognise the BHP Billiton Plc Group assets and liabilities at their fair values, with the excess recorded as goodwill. (A) Reconciliation to US GAAP Material differences between Australian GAAP as followed by the BHP Billiton Group and US GAAP are described below. Refer 'US GAAP Adjustments'. NOTE 49.

The adoption of SAB 101 does not give rise to any differences in revenue recognition. Associated entities and unincorporated joint ventures Under US GAAP, all investments classified as associated entities, as detailed in note 18 'Investments accounted for using the equity method', are accounted for under the equity method of accounting in accordance with APB 18. All unincorporated joint ventures, as detailed in note 45 'Major interests in unincorporated joint ventures', are proportionally accounted for in accordance with Emerging Issues Task Force Opinion ('EITF') 00-01 Investor Balance Sheet and Income Statement Display under the Equity Method for Investments in Certain Partnerships and Other Ventures. The BHP Billiton Group's investment in the Richards Bay Minerals joint venture is comprised of two legal entities Tisand (Pty) Limited and Richards Bay Iron and Titanium (Pty) Limited. Although the BHP Billiton Group owns 51 per cent of Tisand (Pty) Limited, it has not been consolidated under US GAAP in accordance with EITF 96-16 Investor's Accounting for an Investee When the Investor Has a Majority of the Voting Interest but the Minority Shareholder or Shareholders Have Certain Approval or Veto Rights. The substantive participating rights of the minority interests holder in the Richards Bay Minerals joint venture are embodied in the shareholder agreement between the BHP Billiton Group and Rio Tinto which ensures that the Richards Bay Minerals joint venture functions as a single economic entity with the overall profit of the Richards Bay Minerals joint venture shared equally between the venturers. The BHP Billiton Group holds a 57.5 per cent ownership interest in Escondida, which is classified as a joint arrangement. In accordance with EITF 96-16, the BHP Billiton Group has not consolidated this investment. The substantive participating rights of the minority interests holders in the Escondida joint venture include the participation in selection, termination and compensation of management, approval of sales, expenditure, expansions, curtailments, borrowings, settlements and policies and procedures. Period ended 30 June 2000 For the BHP Billiton Limited Group, following a change in balance date from 31 May to 30 June, effective 30 June 2000, all references in this reconciliation to 2000 are to the 13 months ended 30 June 2000 (refer note 1). Under US GAAP, net income for the 12 months ended 30 June 2000 was US$400 million and comprehensive income for the 12 months ended 30 June 2000 was US$674 million. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued US GAAP adjustments Acquisition of BHP Billiton Plc On 29 June 2001, BHP Billiton Limited and BHP Billiton Plc established a DLC merger. A full description of the DLC Merger structure is provided in (Dual Listed Companies Structure and Basis of Preparation of Financial Statements). Under US GAAP, the DLC merger is accounted for as a purchase business combination of the BHP Billiton Plc Group by the BHP Billiton Limited Group. The total assumed purchase consideration of US$11 529 million was calculated by multiplying the number of shares held by BHP Billiton Plc shareholders of 2 319 147 885 on 29 June 2001 by the US$4.9559 adjusted average share price of BHP Billiton Limited's ordinary shares. The average share price was calculated over a period of three days prior to, and subsequent to, the announcement of the DLC merger on 19 March 2001. The average share price is adjusted for the 1:1 equalisation ratio, which is achieved by BHP Billiton Limited's bonus share issue of 1 912 154 524 million shares in the ratio of 1.0651 additional bonus shares for every existing share held - prior to the bonus share adjustment the average share price would be US$10.2344 (i.e. by a factor of 2.0651). The 2 319 147 885 shares held by BHP Billiton Plc shareholders on 29 June 2001 reflect the exercise of rights under the Restricted Share Scheme and the Co-Investment Plan. As such, there were no outstanding stock options, stock appreciation rights or similar issuances of BHP Billiton Plc, and no purchase consideration is attributable to such securities. The cost of acquisition was therefore US$11 529 million, including direct external acquisition costs of US$36 million. The direct external acquisition costs have been expensed as incurred for Australian GAAP purposes. Under US GAAP purchase accounting, the cost of the acquisition is allocated to the fair values of identifiable assets acquired and liabilities assumed. As a result of the fair value exercise, increases in the values of the BHP Billiton Plc Group's inventory, investments, long-term contracts and long-term debt were recognised and fair market values attributed to their other tangible assets mainly property, plant and equipment and undeveloped properties, together with appropriate deferred taxation effects. The difference between the cost of acquisition and the fair value of the assets and liabilities of the BHP Billiton Plc Group has been recorded as goodwill. Fair value adjustments to the recorded amount of inventory and long-term contracts are expensed in the period the inventory is utilised and the long-term contracts are delivered into, and additional amortisation and depreciation are recorded in respect of the fair value adjustments of intangible and tangible assets and the resulting goodwill over the periods of their respective useful economic lives. The adjustments to the assets and liabilities of the BHP Billiton Plc Group to reflect the fair values and allocation of the excess purchase consideration over the fair value of net assets acquired, based on management's best estimates of fair value, are summarised in the shareholders' equity reconciliation and are discussed below: (i) The increase in fair value of inventory was determined based on the difference between the carrying value and the market value of these assets. (ii) The increase in investments relates to increases to the BHP Billiton Plc Group's equity investments. These equity investments have been measured at fair value and any excess of the fair value over the underlying tangible assets and liabilities has been attributed to mineral reserves within the underlying investments. These uplifts to mineral properties are being amortised over their estimated useful lives on a unit of production and, on an investment-by-investment basis. The estimated useful lives are not expected to exceed 30 years. (iii) The increase in property, plant and equipment relates to increases in the carrying value of the BHP Billiton Plc Group's property, plant and equipment to their estimated fair value. The increase in carrying value of the property, plant and equipment is to be amortised over the estimated useful life of the property, plant and equipment, primarily on a unit of production basis. The estimated useful lives range between one year and 33 years. During December 1998, the BHP Billiton Plc Group acquired certain assets from the BHP Billiton Limited Group. The BHP Billiton Plc Group recognised certain fair value adjustments as a result of this acquisition which are being amortised over their useful lives. For Australian GAAP, the fair value adjustments are reversed while for US GAAP these fair value adjustments are reinstated. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued (iv) The amount of total consideration allocated to the BHP Billiton Plc Group's developed and undeveloped properties has been estimated by the BHP Billiton Group management using current estimates of the status and prospects of the BHP Billiton Plc Group's developed and undeveloped property portfolio as contained in the BHP Billiton Plc Group's strategic plans. The undeveloped properties include only those identified properties that have advanced to a stage of development feasibility where management believes reasonable estimates of projected cash flows can be prepared and proven and probable reserves exist. The value allocated to the developed and undeveloped properties was determined utilising a risk adjusted income approach that included earnings discounted by the appropriate cost of capital for the investment. Estimates of future cash flows related to individual developed and undeveloped properties were based on existing estimates of revenues and contribution margin for the project. The increase in developed properties is being amortised over their estimated exploitable useful lives on a project-by-project basis. Amortisation for each project is deferred until such time as production commences. (v) The increase in value of the long-term contracts was determined by attributing a fair value to certain long-term contracts, which were not accorded a value in the BHP Billiton Plc Group's financial statements. (vi) Goodwill represents the remainder of unallocated purchase consideration. Goodwill is currently amortised over its expected useful economic life and in future years will be subject to further periodic impairment tests. (vii) The decrease in long-term debt was as a result of attributing a fair value to fixed interest rate long-term loans which were not recorded at fair value in the BHP Billiton Plc Group's financial statements. (viii) Other differences between Australian GAAP and US GAAP included adjustments for pensions, post-retirement benefits and start-up costs. (ix) Deferred taxes have been computed on the excess of fair value over book value, other than for goodwill, using the applicable statutory tax rates. Preliminary fair value assessments of the assets and liabilities of the BHP Billiton Plc Group were undertaken through the quantification of the purchase price and the preliminary allocation of this to individual businesses and to the underlying assets and liabilities of the individual businesses. Minor revisions to the provisional fair values were undertaken in the year ended 30 June 2002. The revised values of assets and liabilities acquired compared to the provisional values are shown in the table on the following page. Prior period fair value adjustments have not been restated for the revisions. Final Provisional US$M US$M Statement of Financial Position at 30 June 2001 Current assets Cash assets 687 687 Receivables 883 883 Inventories 1 022 1 022 Other financial assets 132 132 Non-current assets Property, plant and equipment 11 567 11 540 Intangibles 3 307 3 278 Other financial assets 2 929 2 971 Current liabilities Payables 1 048 1 048 Interest bearing liabilities 1 300 1 300 Other provisions 221 221 Non-current liabilities Interest bearing liabilities 3 329 3 329 Tax liabilities 2 129 2 161 Other provisions 634 588 Equity minority interests 337 337 Net assets 11 529 11 529 Shareholders' equity Shareholders' equity 11 529 11 529 NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued BHP Steel demerger Under Australian GAAP, the BHP Steel demerger is treated in two components - a distribution to BHP Billiton Limited shareholders of 94 per cent of BHP Steel shares (accounted for as a capital reduction) and a sale of 6 per cent of BHP Steel shares (accounted for as a sale of assets). Under US GAAP, the BHP Steel demerger is classified as a non pro-rata distribution to shareholders and is required to be accounted for as a 100 per cent sale of assets. The implied consideration for the sale of the additional 94 per cent of BHP Steel shares is based on the market price of BHP Steel shares used in determining the bonus issue of BHP Billiton Plc shares to BHP Billiton Plc shareholders. The remaining 6 per cent is measured at the respective sale price. The implied consideration, when compared to the book value of the BHP Steel net assets to be demerged, indicates a shortfall, which is required to be recognised in the result for the period ended 30 June 2002 for US GAAP. The calculation of the book value of the BHP Steel net assets to be demerged includes US GAAP net asset adjustments attributable to BHP Steel. Employee compensation costs In these accounts, the expected cost of awards under various employee ownership plans is charged to the profit and loss account over the vesting period. Under US GAAP, compensation expense arising from variable equity award plans is recognised based on movements in their intrinsic value. Depreciation Revaluations of property, plant and equipment and investments have resulted in upward adjustments to the historical cost values reflected in a revaluation reserve, which is part of total equity. In the case of property, plant and equipment, the depreciation charged against income increases as a direct result of such a revaluation. Since US GAAP does not permit property, plant and equipment to be valued at above historical cost, the depreciation charge has been restated to reflect historical cost depreciation. Following smaller asset write-downs under US GAAP, the higher asset values under US GAAP are being depreciated in accordance with asset utilisation. Refer 'Asset write-downs' below. Asset write-downs At 31 May 1998, the BHP Billiton Limited Group changed its impairment test policy for determining the recoverable amount of non-current assets from an undiscounted to a discounted basis. The discount rate is a risk adjusted market rate which is applied both to determine impairment and to calculate the write-down. Under US GAAP, where an asset is reviewed for impairment, an impairment test is required utilising undiscounted cash flows. If the asset's carrying value exceeds the sum of undiscounted future cash flows, the asset is considered impaired and it is written down to its fair value. These differences created adjustments to the profit and loss account in prior years representing the lower charge to profit and resultant higher asset values for the write-downs calculated under US GAAP. In subsequent financial periods, the difference in asset carrying values is reduced through the inclusion of additional depreciation charges in the profit and loss account. Refer ' Depreciation' above. The movement in the shareholders' equity reconciliation in 2002 for this item largely reflects impacts of the BHP Steel demerger and has been included in that item in the income reconciliation. The charge to profit for the period ended 30 June 2000 reflects the additional write-off of the West Australian HBI plant for US GAAP. Reserves The BHP Billiton Group prepares mineral reserve statements based on the Australasian Code for reporting of Mineral Resources and Ore Reserves, September 1999 (the JORC Code). The information contained in those statements differs in certain respects from that reported to the US Securities and Exchange Commission (SEC) which is prepared with reference to the SEC's Industry Guide 7. This adjustment reflects the impact on depreciation of the difference. Restructuring and employee provisions These accounts include provisions for redundancies associated with organisational restructuring that can be recognised where positions have been identified as being surplus to requirements, provided the circumstances are such that a constructive liability exists. Under US GAAP, a provision for redundancies involving voluntary severance offers is restricted to employees who have accepted these offers. The adjustment is reversed over subsequent periods as the offers are accepted. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Fair value accounting for derivatives Under Australian GAAP, when undertaking risk mitigation transactions, hedge accounting principles are applied, whereby derivatives are matched to the specifically identified commercial risks being hedged. These matching principles are applied to both matured and unmatured transactions. Derivatives undertaken as hedges of anticipated transactions are recognised when such transactions are recognised. Upon recognition of the underlying transaction, derivatives are valued at the appropriate market spot rate. When an underlying transaction can no longer be identified, gains or losses arising from a derivative that has been designated as a hedge of a transaction will be included in the profit and loss account whether or not such derivative is terminated. When a hedge is terminated, the deferred gain or loss that arose prior to termination is: (a) Deferred and included in the measurement of the anticipated transaction when it occurs; or (b) Included in the profit and loss account where the anticipated transaction is no longer expected to occur. The premiums paid on interest rate options and foreign currency put and call options are included in other assets and are deferred and included in the settlement of the underlying transaction. When undertaking strategic or opportunistic financial transactions, all gains and losses are included in the profit and loss account at the end of each reporting period. The premiums paid on strategic financial transactions are included in the profit and loss account at the inception of the contract. For the purpose of deriving US GAAP information, Statement of Financial Accounting Standards No. 133: Accounting for Derivative Instruments and Hedging Activities (SFAS 133) requires that each derivative instrument be recorded in the Statement of Financial Position as either an asset or liability measured at its fair value. On initial application of this Standard the BHP Billiton Limited Group recognised an accumulated loss of US$268 million in respect of the fair value of derivative instruments held on 1 July 2000, which qualified as cash flow hedge transactions. This amount was reported as a component of other comprehensive income. An accumulated gain of US$11 million was recognised in respect of the fair value of derivative instruments which qualified as fair value hedge transactions, offset by a corresponding loss on their associated hedged liabilities held at 1 July 2000. The BHP Billiton Plc Group does not apply hedging principles in accordance with SFAS 133 and marks to market all derivative instruments, taking movements in the fair value of derivative instruments to the profit and loss account. In the year ended 30 June 2001, subsequent gains and losses on cash flow hedges were taken to other comprehensive income and reclassified to profit and loss in the same period the hedged transaction was recognised. Gains and losses on fair value hedges continue to be taken to profit and loss in subsequent periods, as are offsetting gains and losses on hedged liabilities. In both cases, these gains and losses are not recognised under Australian GAAP until the hedged transaction is recognised. Effective 1 July 2001, for US GAAP purposes, the BHP Billiton Limited Group de-designated existing derivative instruments as hedges of underlying transactions. Amounts previously included in other comprehensive income in relation to those derivative instruments previously designated as cash flow hedges will remain until the transactions originally being hedged are recognised, at which time the amounts will be taken to the profit and loss account. Movements in the fair value of derivative instruments since 30 June 2001 are taken to the profit and loss account. Synthetic debt An operating subsidiary, whose functional currency is the US dollar, has obtained financing in various foreign currencies. The operating subsidiary entered into forward exchange contracts to fix the exchange rate between the rand and the various foreign currencies. In these accounts, the arrangement is treated as a synthetic rand debt which at each period end is retranslated into US dollars at the spot rate with the exchange gain or loss that is recognised being included in the profit and loss account. Under US GAAP, synthetic debt accounting is not permitted. As a result, the foreign loan amounts and forward exchange contracts are accounted for separately. Foreign loans are recorded at the exchange rate in effect on the date of the borrowing, with gains and losses arising from currency movements taken to the profit and loss account. The forward exchange contracts are marked to market annually with the resulting gain or loss also taken to the profit and loss account. Realised net exchange gains on sale of assets/closure of operations Net exchange gains or losses reported in shareholders' equity, which relate to assets that have been sold, closed or written down are transferred to retained earnings. US GAAP requires these net exchange gains or losses be recognised in the profit and loss account reflecting that they have, in substance, been realised. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Exploration, evaluation and development expenditures The BHP Billiton Group follows the 'area of interest' method in accounting for petroleum exploration, evaluation and development expenditures. This method differs from the 'successful efforts' method followed by some US companies, and adopted in this reconciliation to US GAAP, in that it permits certain exploration costs in defined areas of interest to be capitalised. Such expenditure capitalised by the BHP Billiton Group is amortised in subsequent years. In respect of Minerals properties, the BHP Billiton Group capitalises exploration and evaluation expenditure where it is expected that the expenditure will be recouped by future exploitation or sale or where a mineral resource has been identified but activities have not reached a stage which permits a reasonable assessment of the existence of commercially recoverable reserves. Under US GAAP, a final feasibility study indicating the existence of commercially recoverable reserves at greenfield properties serves as the trigger point for capitalisation. US GAAP permits expenditure to be capitalised for the purpose of extending or further delineating existing reserves. In subsequent financial periods, amounts amortised (which have been expensed for US GAAP purposes) will be added back when determining the profit result according to US GAAP. Costs of start-up activities The BHP Billiton Group capitalises as part of property, plant and equipment, costs associated with start-up activities at new plants or operations which are incurred prior to commissioning date. These capitalised costs are depreciated in subsequent years. Under US GAAP, costs of start-up activities should be expensed as incurred. Profit on asset sales Under US GAAP, profits arising from the sale of assets cannot be recognised in the period in which the sale occurs where the vendor has a significant continuing association with the purchaser. In such circumstances, any profit arising from a sale is recognised over the life of the continuing arrangements. For the period ended 30 June 2000, the profit on the sale and leaseback of plant and equipment was deferred for US GAAP purposes and will be recognised over the life of the operating lease. Pension plans In these accounts, the net periodic pension cost assessed on an actuarial basis is charged to profit and loss so as to allocate the costs systematically over the employees' service lives. This policy has been adopted for by the BHP Billiton Limited Group to conform with the BHP Billiton Plc Group and was applied in the year ended 30 June 2001. Previously, charges were taken to the profit and loss account as contributions were made to pension plans. Consequently, the BHP Billiton Group recognises periodic pension cost based on actuarial advice in a manner generally consistent with US GAAP. However, differences in the actuarial method used and the timing of recognition of expense components results in different periodic costs and pension assets or liabilities. In addition, any associated foreign exchange gains or losses are required to be eliminated from net income. Other post-retirement benefits In these accounts, post-retirement benefits other than pensions have been accounted for in a manner which is generally consistent with US GAAP except for certain scenarios such as in accounting for plan amendments. In these accounts, amendments to post-retirement benefits provided are taken into account from the date upon which plan amendments are announced. Under US GAAP, plan amendments are only taken into account from the date upon which the plan amendments become effective. Mozal expansion rights In June 2001, BHP Billiton announced an agreement to sell-down a portion of its preferential rights in the Mozal Phase II project to two of its project partners. In these accounts, the consideration was recognised as revenue in the year ended 30 June 2001. A portion of the consideration will be paid in cash and another portion will be delivered to BHP Billiton via a marketing arrangement once production has commenced. This deferred portion will be amortised to the profit and loss account over the period of the sales contract. Under US GAAP, the consideration paid in cash will be recognised as profit from asset sales when received and the deferred consideration portion is considered a derivative and has been recognised on the balance sheet and marked to market with movements in fair value being taken to the profit and loss account. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Change in UK corporate tax rate for petroleum companies Australian GAAP requires tax liabilities and assets to be measured at the rates expected to apply when the underlying timing differences reverse. US GAAP requires the measurement of tax liabilities and assets using tax rates based on enacted tax law. The effect of a change in the UK corporate tax rate for petroleum companies was recognised in June 2002 in these accounts on the basis that the legislation was substantively enacted. This tax rate change will not be recognised for US GAAP purposes until the legislation is enacted. For 2002, an adjustment of US$61 million is reported in the item 'taxation adjustments'. Purchase business combination costs Costs incurred in relation to the DLC merger that were expensed under Australian GAAP represent costs of acquisition that were capitalised under US GAAP. Expenses on spin-off of OneSteel Limited Costs associated with completion of the spin-off of OneSteel Limited are recognised directly in equity for Australian GAAP but are charged as expenses for US GAAP. The financial statements included in the 2001 Form 20-F incorrectly recognised these costs directly in equity. This change in accounting in the year ended 30 June 2001 decreased US GAAP net income by US$30 million, and decreased US GAAP earnings per share by US$0.008 per share. Restoration and rehabilitation costs In these accounts, the expected cost of any committed decommissioning or restoration program, discounted to its net present value, is provided and capitalised at the beginning of each project. The capitalised cost is amortised over the life of the operation and the increase in the net present value of the provision as the discount unwinds is included in net interest and similar items payable. The BHP Billiton Limited Group adopted this policy in the year ended 30 June 2001 to conform with the BHP Billiton Plc Group. In fiscal 2000 and prior years, the provision was determined under US GAAP on an undiscounted basis and the charge to profit was generally based on units of production, so that full provision was made by the end of the assets' economic life. Consolidation of Tubemakers of Australia Ltd (TOA) Prior to consolidation, TOA was accounted for as an associated entity and included in the equity accounting calculations. Under US GAAP equity accounting is included in the consolidated results, while prior to the year ended 30 June 1999 only disclosure by way of note to the accounts was permitted. Thus the carrying value of the original equity interest in TOA is higher under US GAAP, and this is reflected in higher goodwill capitalised and amortised in accordance with US GAAP. The spin-off of OneSteel Limited eliminated this reconciling item. Equity accounting For years ended on or after 30 June 1999, Australian GAAP requires the effect of accounting for associated entities on an equity basis to be shown in the consolidated results, as required by US GAAP. In prior periods, Australian GAAP permitted the effect of accounting for associated companies on an equity basis to be shown as supplementary information. The Australian GAAP adjustment to retained earnings on initial adoption of equity accounting is recognised in the result for the period ended 30 June 2000 for US GAAP. Employee Share Plan loans Under the Employee Share Plan, loans have been made to employees for the purchase of shares in BHP Billiton Limited. Under US GAAP, the amount outstanding as an obligation to the BHP Billiton Limited Group, which has financed equity, is required to be eliminated from total shareholders' equity. In addition, any foreign exchange gains or losses on the outstanding loan balances are required to be eliminated from net income. Investments In these accounts, certain unlisted investments are marked to market annually based on third party valuations. The increase/ (decrease) in the value of the investments is recognised in the profit and loss account. Under US GAAP such investments are adjusted to reflect the increase in guaranteed surrender value of the investment, but are not permitted to be marked to market. In these accounts, certain investments in marketable securities are classified as exploration assets and are carried at estimated recoverable amount. Under US GAAP, such investments are classified as available for sale and are marked to market with changes in fair value recognised as a component of comprehensive income. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Secondary share issuance During September 2000, BHP Billiton Plc undertook a secondary issuance of shares on the London Stock Exchange. The shares were issued in pounds sterling, however to fix the proceeds received on the share issuance in US dollars, BHP Billiton Plc utilised a number of hedging instruments to lock in the exchange rate between pounds sterling and US dollars. This hedging activity gave rise to a loss being realised due to the movement in the pound sterling against the US dollar. BHP Billiton Plc reported this loss as an offset against the share proceeds, which was then credited to paid in capital. Under US GAAP, the loss would not qualify as a hedged item under SFAS 133. As such, the loss is recognised in the profit and loss in the period the loss was realised. Taxation adjustments In these accounts, potential tax expense of US$47 million has not been recognised in 2002, mainly relating to the tax impact of unrealised foreign exchange gains or losses on US dollar net debt held by subsidiaries which retain local currency records for tax purposes. For US GAAP, a tax expense is recognised reflecting the existence of the foreign exchange gains or losses in the accounts of the respective entity. This adjustment is reported in the item ' taxation adjustments'. (B) Employee compensation costs The BHP Billiton Group has applied the principles of US Accounting Principles Board Opinion No. 25 in the determination of employee compensation costs arising from the various employee ownership plans. Had the fair value basis of accounting in US Statement of Financial Accounting Standards No. 123 been used to account for compensation costs, the following net income and earnings per share amounts would result: 2002 2001 2000 US$M US$M US$M Net income As reported 1 249 882 589 Proforma 1 224 897 589 Basic earnings per share (a) (b) As reported 0.207 0.239 0.161 Proforma 0.203 0.243 0.161 Diluted earnings per share (b) (c) As reported 0.207 0.238 0.161 Proforma 0.203 0.242 0.161 (a) Based on net profit attributable to members of BHP Billiton Group. (b) Comparative data has been adjusted to take into account the bonus share issue effective 29 June 2001. Refer note 31. (c) Refer note 12. (C) Impact of new accounting standards In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 141: Business Combinations (SFAS141) and Statement of Financial Accounting Standards No. 142: Goodwill and Other Intangible Assets (SFAS142). In August 2001, the FASB also issued Statement of Financial Accounting Standards No. 143: Accounting for Asset Retirement Obligations (SFAS143) and Statement of Financial Accounting Standards No. 144: Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS144). In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146: Accounting for Costs Associated with Exit or Disposal Activities (SFAS146). For the purpose of deriving US GAAP financial information of the BHP Billiton Group, SFAS141 applies to purchase business combinations entered into after 30 June 2001. SFAS142 , SFAS143 and SFAS144 will apply for the year ending 30 June 2003, while SFAS146 is effective for exit or disposal activities initiated after 31 December 2003. The BHP Billiton Group has not adopted any of these standards early for the purpose of the June 2002 financial statements. NOTE 49. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued SFAS141 changes the accounting for business combinations to a single purchase accounting method. SFAS141 also changes the recognition criteria for intangible assets other than goodwill, and expands disclosure requirements in relation to business combinations. SFAS142 changes the accounting for acquired goodwill and other intangible assets by requiring that goodwill and intangible assets with indefinite useful lives not be amortised. Under SFAS142, the carrying amount of such assets will be subject to impairment tests at least on an annual basis. SFAS143 changes accounting for the retirement of tangible long-lived assets by requiring that the fair value of legal obligations associated with the retirement of such assets be recognised as a liability and capitalised as part of the cost of those assets. SFAS144 requires one accounting model to be used for long-lived assets to be disposed of by sale, whether previously held and used or newly acquired, and will broaden the presentation of discontinued operations to include more disposal transactions. SFAS146 requires that costs associated with exit or disposal activities be recognised when they are incurred rather than at the date of a commitment to an exit or disposal plan. The BHP Billiton Group has not evaluated the potential impact of any of these new standards on its future financial performance or financial position. Addendum to BHP Billiton Plc Annual Report 2002 Note 34 to the financial statements - US Generally Accepted Accounting Principles Disclosures - has been revised. This version supersedes that included in the BHP Billiton Plc Annual Report 2002. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES The financial statements of the BHP Billiton Group are prepared in accordance with UK Generally Accepted Accounting Principles (GAAP). The financial statements, analyses and reconciliations presented in this note represent the financial information which would be required if US GAAP had been applied instead of UK GAAP. Certain additional disclosures that would normally accompany these disclosures were they being prepared in the context of a filing with the US Securities and Exchange Commission have been omitted. DLC merger On 29 June 2001, BHP Billiton Plc (formerly Billiton Plc) consummated the Dual Listed Companies (DLC) merger with BHP Billiton Limited (formerly BHP Limited). A description of the DLC merger structure is provided in 'Dual Listed Companies Structure and Basis of Preparation of Financial Statements'. In accounting for this transaction, the most significant difference between UK GAAP and US GAAP is that under UK GAAP, the DLC merger has been accounted for as a merger (pooling of interests) in accordance with UK Financial Reporting Standard 6: Acquisitions and Mergers, whereas under US GAAP the DLC merger is accounted for as a purchase business combination with the BHP Billiton Limited Group acquiring the BHP Billiton Plc Group. The BHP Billiton Limited Group has been identified as the acquirer because of the majority ownership interest of BHP Billiton Limited shareholders in the DLC structure. In a merger, the assets, liabilities and equity of the BHP Billiton Plc Group and of the BHP Billiton Limited Group are combined at their respective book values as determined under UK GAAP. Under US GAAP, the reconciliation of shareholders' equity includes the purchase adjustments required under US GAAP to recognise the BHP Billiton Plc Group assets and liabilities at their fair values, with the excess recorded as goodwill. Although UK GAAP and US GAAP both require the consolidation of the BHP Billiton Plc Group with the BHP Billiton Limited Group at 30 June 2001, UK GAAP also requires that their respective financial statements for periods prior to the date the DLC merger was consummated are combined. Under purchase accounting, the retroactive combination of financial statements is not appropriate. As the BHP Billiton Limited Group is the accounting acquirer, and is the 'predecessor' to the BHP Billiton Group, for the years ended 30 June 2001 and 2000, the BHP Billiton Group's net income under UK GAAP, as presented in the financial statements of the BHP Billiton Group, when represented under US GAAP, becomes the net income of the BHP Billiton Limited Group NOTE 34.

NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Basis of presentation under US GAAP Revenue recognition SAB 101 'Revenue recognition in Financial Statements' became applicable to the BHP Billiton Group for the year ended 30 June 2001. The adoption of SAB 101 does not give rise to any differences in revenue recognition. Debtors In accordance with UK GAAP, certain debtors are included on the balance sheet, which are considered to have been sold and are not included on the balance sheet under US GAAP. The value of debtors at 30 June 2002 which were the subject of such treatment was US$141 million (2001: US$278 million). Joint ventures and joint arrangements Under US GAAP, all investments classified as joint ventures, as detailed under the heading 'Joint ventures' in note 1 'Principal subsidiaries, joint ventures, associates and joint arrangements', are accounted for under the equity method of accounting in accordance with APB 18. All joint arrangements, as detailed under the heading 'Proportionally included joint arrangements' in note 1, are also proportionally accounted for in accordance with Emerging Issues Task Force Opinion ('EITF') 00-01 Investor Balance Sheet and Income Statement Display under the Equity Method for Investments in Certain Partnerships and Other Ventures. As disclosed in note 1, the BHP Billiton Group's investment in the Richards Bay Minerals joint venture is comprised of two legal entities Tisand (Pty) Limited and Richards Bay Iron and Titanium (Pty) Limited. Although the BHP Billiton Group owns 51 per cent of Tisand (Pty) Limited, it has not been consolidated under US GAAP in accordance with EITF 96-16 Investor's Accounting for an Investee When the Investor Has a Majority of the Voting Interest but the Minority Shareholder or Shareholders Have Certain Approval or Veto Rights. The substantive participating rights of the minority interests holder in the Richards Bay Minerals joint venture are embodied in the shareholder agreement between the BHP Billiton Group and Rio Tinto which ensures that the Richards Bay Minerals joint venture functions as a single economic entity with the overall profit of the Richards Bay Minerals joint venture shared equally between the venturers. As disclosed in note 1, the BHP Billiton Group holds a 57.5 per cent ownership interest in Escondida, which is classified as a joint arrangement. In accordance with EITF 96-16, the BHP Billiton Group has not consolidated this investment. The substantive participating rights of the minority interests holder in the Escondida joint venture include the participation in selection, termination and compensation of management, approval of sales, expenditure, expansions, curtailments, borrowings, settlements and policies and procedures. Cash flows Under US GAAP, dividends from joint ventures and associates, cash flows from returns on investments and servicing of finance, and tax paid are included in operating activities. In addition, capital expenditure and acquisitions and disposals are included as investing activities. Proceeds from the issuance of shares, increases and decreases in debt, and dividends paid, are included as financing activities. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Under UK GAAP, cash is defined as cash in hand and deposits repayable on demand, less overdrafts repayable on demand. Under US GAAP, cash is defined as cash in hand and deposits but also includes cash equivalents, which are short term investments with original maturities of less than three months. US GAAP adjustments Elimination of the BHP Billiton Plc Group financial information This adjustment eliminates the pre-acquisition net income of the BHP Billiton Plc Group recorded in the BHP Billiton Group UK GAAP financial statements for the years ended 30 June 2001 and 30 June 2000. This elimination is not applicable at 30 June 2002 or for subsequent post-acquisition periods. Acquisition of BHP Billiton Plc On 29 June 2001, BHP Billiton Limited and BHP Billiton Plc established a DLC merger. A full description of the DLC Merger structure is provided in 'Dual Listed Companies Structure and Basis of Preparation of Financial Statements'. Under US GAAP, the DLC merger is accounted for as a purchase business combination of the BHP Billiton Plc Group by the BHP Billiton Limited Group. The total assumed purchase consideration of US$11 529 million was calculated by multiplying the number of shares held by BHP Billiton Plc shareholders of 2 319 147 885 on 29 June 2001 by the US$4.9559 adjusted average share price of BHP Billiton Limited's ordinary shares. The average share price was calculated over a period of three days prior to, and subsequent to, the announcement of the DLC merger on 19 March 2001. The average share price is adjusted for the 1:1 equalisation ratio, which is achieved by BHP Billiton Limited's bonus share issue of 1 912 154 524 million shares in the ratio of 1.0651 additional bonus shares for every existing share held - prior to the bonus share adjustment the average share price would be US$10.2344 (i.e. by a factor of 2.0651). The 2 319 147 885 shares held by BHP Billiton Plc shareholders on 29 June 2001 reflect the exercise of rights under the Restricted Share Scheme and the Co-Investment Plan. As such, there were no outstanding stock options, stock appreciation rights or similar issuances of BHP Billiton Plc, and no purchase consideration is attributable to such securities. The cost of acquisition was therefore US$11 529 million, including direct external acquisition costs of US$36 million. The direct external acquisition costs have been expensed as incurred for UK GAAP purposes. Under US GAAP purchase accounting, the cost of the acquisition is allocated to the fair values of identifiable assets acquired and liabilities assumed. As a result of the fair value exercise, increases in the values of the BHP Billiton Plc Group's inventory, investments, long-term contracts and long-term debt were recognised and fair market values attributed to their other tangible assets mainly property, plant and equipment and undeveloped properties, together with appropriate deferred taxation effects. The difference between the cost of acquisition and the fair value of the assets and liabilities of the BHP Billiton Plc Group has been recorded as goodwill. Fair value adjustments to the recorded amount of inventory and long-term contracts are expensed in the period the inventory is utilised and the long-term contracts are delivered into, and additional amortisation and depreciation are recorded in respect of the fair value adjustments of intangible and tangible assets and the resulting goodwill over the periods of their respective useful economic lives. The adjustments to the assets and liabilities of the BHP Billiton Plc Group to reflect the fair values and allocation of the excess purchase consideration over the fair value of net assets acquired, based on management's best estimates of fair value, are summarised in the shareholders' equity reconciliation and are discussed below: i. The increase in fair value of inventory was determined based on the difference between the carrying value and the market value of these assets. (ii) The increase in investments relates to increases to the BHP Billiton Plc Group's equity investments. These equity investments have been measured at fair value and any excess of the fair value over the underlying tangible assets and liabilities has been attributed to mineral reserves within the underlying investments. These uplifts to mineral properties are being amortised over their estimated useful lives on a unit of production and, on an investment-by-investment basis. The estimated useful lives are not expected to exceed 30 years. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued (iii) The increase in property, plant and equipment relates to increases in the carrying value of the BHP Billiton Plc Group's property, plant and equipment to their estimated fair value. The increase in carrying value of the property, plant and equipment is to be amortised over the estimated useful life of the property, plant and equipment, primarily on a unit of production basis. The estimated useful lives range between one year and 33 years. During December 1998, the BHP Billiton Plc Group acquired certain assets from the BHP Billiton Limited Group. The BHP Billiton Plc Group recognised certain fair value adjustments as a result of this acquisition which are being amortised over their useful lives. As a result of the application of merger accounting under UK GAAP, the fair value adjustments are reversed. For US GAAP these fair value adjustments are reinstated. (iv) The amount of total consideration allocated to the BHP Billiton Plc Group's developed and undeveloped properties has been estimated by the BHP Billiton Group management using current estimates of the status and prospects of the BHP Billiton Plc Group's developed and undeveloped property portfolio as contained in the BHP Billiton Plc Group's strategic plans. The undeveloped properties include only those identified properties that have advanced to a stage of development feasibility where management believes reasonable estimates of projected cash flows can be prepared and proven and probable reserves exist. The value allocated to the developed and undeveloped properties was determined utilising a risk adjusted income approach that included earnings discounted by the appropriate cost of capital for the investment. Estimates of future cash flows related to individual developed and undeveloped properties were based on existing estimates of revenues and contribution margin for the project. The increase in developed properties is being amortised over their estimated exploitable useful lives on a project-by-project basis. Amortisation for each project is deferred until such time as production commences. (v) The increase in value of the long-term contracts was determined by attributing a fair value to certain long-term contracts, which were not accorded a value in the BHP Billiton Plc Group's financial statements. (vi) Goodwill represents the remainder of unallocated purchase consideration. Goodwill is currently amortised over its expected useful economic life and in future years will be subject to periodic impairment tests. (vii) The decrease in long-term debt was as a result of attributing a fair value to fixed interest rate long-term loans which were not recorded at fair value in the BHP Billiton Plc Group's financial statements. (viii) Other differences between UK GAAP and US GAAP included adjustments for pensions, post-retirement benefits and start up costs. (ix) Deferred taxes have been computed on the excess of fair value over book value, other than for goodwill, using the applicable statutory tax rates. Preliminary fair value assessments of the assets and liabilities of the BHP Billiton Plc Group were undertaken through the quantification of the purchase price and the preliminary allocation of this to individual businesses and to the underlying assets and liabilities of the individual businesses. Minor revisions to the provisional fair values were undertaken in the year ended 30 June 2002. The revised values of assets and liabilities acquired compared to the provisional values are shown in the table below. Prior period fair value adjustments have not been restated for the revisions.

US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued BHP Steel demerger Under UK GAAP, the BHP Steel demerger is treated in two components - a distribution to BHP Billiton Limited shareholders of 94 per cent of BHP Steel shares (accounted for as a capital reduction) and a sale of 6 per cent of BHP Steel shares (accounted for as a sale of assets). Under US GAAP, the BHP Steel demerger is classified as a non pro-rata distribution to shareholders and is required to be accounted for as a 100 per cent sale of assets. The implied consideration for the sale of the additional 94 per cent of BHP Steel shares is based on the market price of BHP Steel shares used in determining the bonus issue of BHP Billiton Plc shares to BHP Billiton Plc shareholders. The remaining 6 per cent is measured at the respective sale price. The implied consideration, when compared to the book value of the BHP Steel net assets to be demerged, indicates a shortfall, which is required to be recognised in the result for the period ended 30 June 2002 for US GAAP.The calculation of the book value of the BHP Steel net assets to be demerged includes US GAAP net asset adjustments attributable to BHP Steel. Employee compensation costs In these accounts, the expected cost of awards under various employee ownership plans is charged to the profit and loss account over the vesting period. Under US GAAP, compensation expense arising from variable equity award plans is recognised based on movements in their intrinsic value. Depreciation Revaluations of property, plant and equipment and investments have resulted in upward adjustments to the historical cost values reflected in a revaluation reserve, which is part of total equity. In the case of property, plant and equipment, the depreciation charged against income increases as a direct result of such a revaluation. Since US GAAP does not permit property, plant and equipment to be valued at above historical cost, the depreciation charge has been restated to reflect historical cost depreciation. Following smaller asset write-downs under US GAAP, the higher asset values under US GAAP are being depreciated in accordance with asset utilisation. Refer 'Asset write-downs' below. Asset write-downs At 31 May 1998, the BHP Billiton Limited Group changed its impairment test policy for determining the recoverable amount of non-current assets from an undiscounted to a discounted basis. The discount rate is a risk adjusted market rate which is applied both to determine impairment and to calculate the write-down. Under US GAAP, where an asset is reviewed for impairment, an impairment test is required utilising undiscounted cash flows. If the asset's carrying value exceeds the sum of undiscounted future cash flows, the asset is considered impaired and it is written down to its fair value. These differences created adjustments to the profit and loss account in prior years representing the lower charge to profit and resultant higher asset values for the write-downs calculated under US GAAP. In subsequent financial periods, the difference in asset carrying values is reduced through the inclusion of additional depreciation charges in the profit and loss account. Refer ' Depreciation' above. The movement in the shareholders' equity reconciliation in 2002 for this item largely reflects impacts of the BHP Steel demerger and has been included in that item in the income reconciliation. The charge to profit for the period ended 30 June 2000 reflects the additional write-off of the West Australian HBI plant for US GAAP. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Reserves The BHP Billiton Group prepares mineral reserve statements based on the Australasian Code for reporting of Mineral Resources and Ore Reserves, September 1999 (the JORC Code). The information contained in these statements differs in certain respects from that reported to the US Securities and Exchange Commission (SEC) which is prepared with reference to the SEC's Industry Guide 7. This adjustment reflects the impact on depreciation of the difference. Restructuring and employee provisions These accounts include provisions for redundancies associated with organisational restructuring that can be recognised where positions have been identified as being surplus to requirements, provided the circumstances are such that a constructive liability exists. Under US GAAP, a provision for redundancies involving voluntary severance offers is restricted to employees who have accepted these offers. The adjustment is reversed over subsequent periods as the offers are accepted. Fair value accounting for derivatives Under UK GAAP, when undertaking risk mitigation transactions, hedge accounting principles are applied, whereby derivatives are matched to the specifically identified commercial risks being hedged. These matching principles are applied to both matured and unmatured transactions. Derivatives undertaken as hedges of anticipated transactions are recognised when such transactions are recognised. Upon recognition of the underlying transaction, derivatives are valued at the appropriate market spot rate. When an underlying transaction can no longer be identified, gains or losses arising from a derivative that has been designated as a hedge of a transaction will be included in the profit and loss account whether or not such derivative is terminated. When a hedge is terminated, the deferred gain or loss that arose prior to termination is: (a) Deferred and included in the measurement of the anticipated transaction when it occurs; or (b) Included in the profit and loss account where the anticipated transaction is no longer expected to occur. The premiums paid on interest rate options and foreign currency put and call options are included in other assets and are deferred and included in the settlement of the underlying transaction. When undertaking strategic or opportunistic financial transactions, all gains and losses are included in the profit and loss account at the end of each reporting period. The premiums paid on strategic financial transactions are included in the profit and loss account at the inception of the contract. For the purpose of deriving US GAAP information, Statement of Financial Accounting Standards No. 133: Accounting for Derivative Instruments and Hedging Activities (SFAS 133) requires that each derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value. On initial application of this Standard the BHP Billiton Limited Group recognised an accumulated loss of US$268 million in respect of the fair value of derivative instruments held on 1 July 2000, which qualified as cash flow hedge transactions. This amount was reported as a component of other comprehensive income. An accumulated gain of US$11 million was recognised in respect of the fair value of derivative instruments which qualified as fair value hedge transactions, offset by a corresponding loss on their associated hedged liabilities held at 1 July 2000. The BHP Billiton Plc Group does not apply hedging principles in accordance with SFAS 133 and marks to market all derivative instruments, taking movements in the fair value of derivative instruments to the profit and loss account. In the year ended 30 June 2001, subsequent gains and losses on cash flow hedges were taken to other comprehensive income and reclassified to profit and loss in the same period the hedged transaction was recognised. Gains and losses on fair value hedges continue to be taken to profit and loss in subsequent periods, as are offsetting gains and losses on hedged liabilities. In both cases, these gains and losses are not recognised under UK GAAP until the hedged transaction is recognised. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Effective 1 July 2001, for US GAAP purposes, the BHP Billiton Limited Group de-designated existing derivative instruments as hedges of underlying transactions. Amounts previously included in other comprehensive income in relation to those derivative instruments previously designated as cash flow hedges will remain until the transactions originally being hedged are recognised, at which time the amounts will be taken to the profit and loss account. Movements in the fair value of derivative instruments since 30 June 2001 are taken to the profit and loss account. Synthetic debt An operating subsidiary, whose functional currency is the US dollar, has obtained financing in various foreign currencies. The operating subsidiary entered into forward exchange contracts to fix the exchange rate between the rand and the various foreign currencies. In these accounts, the arrangement is treated as a synthetic rand debt which at each period end is retranslated into US dollars at the spot rate with the exchange gain or loss that is recognised being included in the profit and loss account. Under US GAAP, synthetic debt accounting is not permitted. As a result, the foreign loan amounts and forward exchange contracts are accounted for separately. Foreign loans are recorded at the exchange rate in effect on the date of the borrowing, with gains and losses arising from currency movements taken to the profit and loss account. The forward exchange contracts are marked to market annually with the resulting gain or loss also taken to the profit and loss account. Realised net exchange gains on sale of assets/closure of operations Net exchange gains or losses reported in shareholders' equity, which relate to assets that have been sold, closed or written down are transferred to retained earnings. US GAAP requires these net exchange gains or losses be recognised in the profit and loss account reflecting that they have, in substance, been realised. Exploration, evaluation and development expenditures The BHP Billiton Group follows the 'successful efforts' method under UK GAAP in accounting for petroleum exploration, evaluation and development expenditures. This method differs from the 'successful efforts' method followed by some US companies, and adopted in this reconciliation to US GAAP, in that it permits certain exploration costs in defined areas of interest to be capitalised. Such expenditure capitalised by the BHP Billiton Group is amortised in subsequent years. In respect of Minerals properties, the BHP Billiton Group capitalises exploration and evaluation expenditure where it is expected that the expenditure will be recouped by future exploitation or sale or where a mineral resource has been identified but activities have not reached a stage which permits a reasonable assessment of the existence of commercially recoverable reserves. Under US GAAP, a final feasibility study indicating the existence of commercially recoverable reserves at greenfield properties serves as the trigger point for capitalisation. US GAAP permits expenditure to be capitalised for the purposes of extending or further delineating existing reserves. In subsequent financial periods, amounts amortised (which have been expensed for US GAAP purposes) will be added back when determining the profit result according to US GAAP. Costs of start-up activities The BHP Billiton Group capitalises as part of property, plant and equipment, costs associated with start-up activities at new plants or operations which are incurred prior to commissioning date. These capitalised costs are depreciated in subsequent years. Under US GAAP, costs of start-up activities should be expensed as incurred. Profit on asset sales Under US GAAP, profits arising from the sale of assets cannot be recognised in the period in which the sale occurs where the vendor has a significant continuing association with the purchaser. In such circumstances, any profit arising from a sale is recognised over the life of the continuing arrangements. For the period ended 30 June 2000, the profit on the sale and leaseback of plant and equipment was deferred for US GAAP purposes and will be recognised over the life of the operating lease. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Pension plans Under UK GAAP, the net periodic pension cost assessed on an actuarial basis is charged to profit and loss so as to allocate the costs systematically over the employees' service lives. Under UK GAAP, this policy has been adopted for all periods presented and resulted in changes in policy by the BHP Billiton Limited Group to conform with the BHP Billiton Plc Group in the year ended 30 June 2001. Previously, charges were taken to the profit and loss account as contributions were made to pension plans. Consequently, the BHP Billiton Group recognises periodic pension cost based on actuarial advice in a manner generally consistent with US GAAP. However, differences in the actuarial method used and the timing of recognition of expense components results in different periodic costs and pension assets or liabilities. In addition, any associated foreign exchange gains or losses are required to be eliminated from net income. Post-retirement benefits In these accounts, post-retirement benefits other than pensions have been accounted for in accordance with the provisions of SSAP 24, which are generally consistent with the provisions of SFAS 106 for the purposes of US GAAP except for certain scenarios such as in accounting for plan amendments. Under UK GAAP, amendments to post-retirement benefits provided are taken into account from the date upon which plan amendments are announced. Under US GAAP, plan amendments are only taken into account from the date upon which the plan amendments become effective. Mozal expansion rights In June 2001, BHP Billiton announced an agreement to sell-down a portion of its preferential rights in the Mozal Phase II project to two of its project partners. In these accounts, the consideration was recognised as revenue in the year ended 30 June 2001. A portion of the consideration will be paid in cash and another portion will be delivered to BHP Billiton via a marketing arrangement once production has commenced. This deferred portion will be amortised to the profit and loss account over the period of the sales contract. Under US GAAP, the consideration paid in cash will be recognised as profit from asset sales when received and the deferred consideration portion is considered a derivative and has been recognised on the balance sheet and marked to market with movements in fair value being taken to the profit and loss account. Change in UK corporate tax rate for petroleum companies UK GAAP requires tax liabilities and assets to be measured at the amounts expected to apply using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date. US GAAP requires the measurement of tax liabilities and assets using tax rates based on enacted tax law. The effect of a change in the UK corporate tax rate for petroleum companies was recognised in June 2002 for UK GAAP on the basis that the legislation was substantively enacted. This tax rate change will not be recognised for US GAAP purposes until the legislation is enacted. For 2002, an adjustment of US$61 million is reported in the item 'taxation adjustments'. Purchase business combination costs Costs incurred in relation to the DLC merger that were expensed under UK GAAP represent costs of acquisition that were capitalised under US GAAP. Expenses on spin-off of OneSteel Limited Costs associated with completion of the spin-off of OneSteel Limited are recognised directly in equity for UK GAAP but are charged as expenses for US GAAP. Previously published financial statements incorrectly recognised these costs directly in equity. This change in accounting in the year ended 30 June 2001 decreased US GAAP net income by US$30 million, and decreased US GAAP earnings per share by US$0.008 per share. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued Restoration and rehabilitation costs Under UK GAAP, the expected cost of any committed decommissioning or restoration program, discounted to its net present value, is provided and capitalised at the beginning of each project. The capitalised cost is amortised over the life of the operation and the increase in the net present value of the provision as the discount unwinds is included in net interest and similar items payable. Under UK GAAP, this policy has been adopted for all periods presented. In fiscal 2000 and prior years, the provision was determined under US GAAP on an undiscounted basis and the charge to profit was generally based on units of production, so that full provision was made by the end of the assets' economic life. Consolidation of Tubemakers of Australia Ltd (TOA) Prior to consolidation, TOA was accounted for as an associated entity and included in the equity accounting calculations. Under US GAAP equity accounting is included in the consolidated results, while prior to the year ended 30 June 1999 only disclosure by way of note to the accounts was permitted. Thus the carrying value of the original equity interest in TOA is higher under US GAAP, and this is reflected in higher goodwill capitalised and amortised in accordance with US GAAP. The spin-off of OneSteel Limited eliminated this reconciling item. Employee Share Plan loans Under the Employee Share Plan, loans have been made to employees for the purchase of shares in BHP Billiton Limited. Under US GAAP, the amount outstanding as an obligation to the BHP Billiton Limited Group, which has financed equity, is required to be eliminated from total shareholders' equity. In addition, any foreign exchange gains or losses on the outstanding loan balances are required to be eliminated from net income Investments Under UK GAAP certain unlisted investments are marked to market annually based on third party valuations. The increase/(decrease) in the value of the investments is recognised in the profit and loss account. Under US GAAP such investments are adjusted to reflect the increase in guaranteed surrender value of the investment, but are not permitted to be marked to market. Under UK GAAP certain investments in marketable securities are classified as exploration assets and are carried at estimated recoverable amount. Under US GAAP, such investments are classified as available for sale and are marked to market with changes in fair value recognised as a component of comprehensive income. Secondary share issuance During September 2000, BHP Billiton Plc undertook a secondary issuance of shares on the London Stock Exchange. The shares were issued in pounds sterling, however to fix the proceeds received on the share issuance in US dollars, BHP Billiton Plc utilised a number of hedging instruments to lock in the exchange rate between pounds sterling and US dollars. This hedging activity gave rise to a loss being realised due to the movement in the pound sterling against the US dollar. BHP Billiton Plc reported this loss as an offset against the share proceeds, which was then credited to paid in capital. Under US GAAP, the loss would not qualify as a hedged item under SFAS 133. As such, the loss is recognised in the profit and loss in the period the loss was realised. Taxation adjustments In these accounts, potential tax expense of US$47 million has not been recognised in 2002, mainly relating to the tax impact of unrealised foreign exchange gains or losses on US dollar net debt held by subsidiaries which retain local currency records for tax purposes. For US GAAP, a tax expense is recognised reflecting the existence of the foreign exchange gains or losses in the accounts of the respective entity. This adjustment is reported in the item ' taxation adjustments'. NOTE 34. US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES DISCLOSURES continued (B) Employee compensation costs The BHP Billiton Group has applied the principles of US Accounting Principles Board Opinion No. 25 in the determination of employee compensation costs arising from the various employee ownership plans. Had the fair value basis of accounting in US Statement of Financial Accounting Standards No. 123 been used to account for compensation costs, the following net income and earnings per share amounts would result: 2002 2001 2000 US$M US$M US$M Net income As reported 1 249 882 400 Proforma 1 224 897 400 Basic earnings per share (a) (b) As reported 0.207 0.239 0.109 Proforma 0.203 0.243 0.109 Diluted earnings per share (b) (c) As reported 0.207 0.238 0.109 Proforma 0.203 0.242 0.109 (a) Based on net profit attributable to members of BHP Billiton Group. (b) Comparative data has been adjusted to take into account the bonus share issue effective 29 June 2001. Refer note 23. (c) Refer note 12. (C) Impact of new accounting standards In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 141: Business Combinations (SFAS141) and Statement of Financial Accounting Standards No. 142: Goodwill and Other Intangible Assets (SFAS142). In August 2001, the FASB also issued Statement of Financial Accounting Standards No. 143: Accounting for Asset Retirement Obligations (SFAS143) and Statement of Financial Accounting Standards No. 144: Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS144). In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146: Accounting for Costs Associated with Exit or Disposal Activities (SFAS146). For the purpose of deriving US GAAP financial information of the BHP Billiton Group, SFAS141 applies to purchase business combinations entered into after 30 June 2001. SFAS142, SFAS143 and SFAS144 will apply for the year ending 30 June 2003 while SFAS146 is effective for exit or disposal activities initiated after 31 December 2003. The BHP Billiton Group has not adopted any of these standards early for the purpose of the June 2002 financial statements. SFAS141 changes the accounting for business combinations to a single purchase accounting method. SFAS141 also changes the recognition criteria for intangible assets other than goodwill, and expands disclosure requirements in relation to business combinations. SFAS142 changes the accounting for acquired goodwill and other intangible assets by requiring that goodwill and intangible assets with indefinite useful lives not be amortised. Under SFAS142, the carrying amount of such assets will be subject to impairment tests at least on an annual basis. SFAS143 changes accounting for the retirement of tangible long-lived assets by requiring that the fair value of legal obligations associated with the retirement of such assets be recognised as a liability and capitalised as part of the cost of those assets. SFAS144 requires one accounting model to be used for long-lived assets to be disposed of by sale, whether previously held and used or newly acquired, and will broaden the presentation of discontinued operations to include more disposal transactions. SFAS146 requires that costs associated with exit or disposal activities be recognised when they are incurred rather than at the date of a commitment to an exit or disposal plan. The BHP Billiton Group has not evaluated the potential impact of any of these new standards on its future financial performance or financial position.
