(b) Despite clause 7.1(a), the onus is upon the Buyer to establish the existence and extent of any Material Adverse Change.

(c) A Material Adverse Change occurs where, as a result of the occurrence of a Force Majeure Event a buyer who is bound to purchase the Shares in Premier Coal at arm’s length on the terms and conditions set out in this agreement (a Notional Buyer) would reasonably form the view that the value of the Shares in Premier Coal had, by reason of that Force Majeure Event, been reduced by more than $30 million, after recognising the value of and accounting for:

(i) and assessing the probability of recovery under all insurances available to Premier Coal in respect of the Force Majeure Event and its consequences; and

The Expert must be instructed to make a determination as soon as reasonably practicable and no later than 28 days after the date of the Expert’s appointment of the amount of the Value Diminution (and not simply whether it is more or less than $30 million) that is, as far as practicable in the circumstances, fair to both the Buyer and the Sellers. Clause 9.6 applies to any such determination by an Expert, with such modifications as the context requires. The costs of the Expert are to be borne by the Buyer and Sellers equally.

Schedule 10—Accounting principles and policies

1. Accounting principles and policies to be applied in preparation of the Base Balance Sheet and the Completion Balance Sheet

1.1 Basis of preparation

The balance sheet comprises the combined position of wholly owned subsidiaries of ‘Wesfarmers: Premier Coal; and Wesfarmers Char and has been prepared on a historical cost basis, except as noted below.

In preparing the balance sheet, the financial information of the subsidiaries has been aggregated.

The Companies are being sold on a cash, debt and intercompany free basis, however, in presenting this balance sheet, no adjustments have been made to eliminate these balances for the Companies. The intercompany balances resulting from intra-company transactions have also not been eliminated in full.

In addition, the Companies are members of the Wesfarmers tax consolidated group and subject to the group’s Tax Sharing and Tax Funding Deed (TSA). Under the TSA, the Companies will be released from liability in respect of income tax liabilities, calculated up to completion that are due after completion, where the entities make a clean exit payment in accordance with the law. Taxation balances have been presented within the balance sheet.

Lastly, a provision of $10 million which has been presented in the balance sheet will be retained by Wesfarmers upon divestment of the Companies.

The balance sheet is presented in Australian dollars and all values are rounded to the nearest thousand dollars ($000).

The directors have determined that in order for the financial position to be presented fairly, the recognition and measurement criteria of assets and liabilities will be as outlined below.

1.2 Cash and cash equivalents

Cash and short-term deposits in the balance sheet comprise cash at bank and on hand and short-term deposits with an original maturity of three months or less.

1.3 Trade and other receivables

Trade receivables generally have terms up to 30 days, are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method, less an allowance for impairment.

Collectability and impairment of trade and other receivables are assessed on an ongoing basis at a Companies level. Individual debts that are known to be uncollectable are written off when identified. An impairment allowance is recognised when there is objective evidence that the Companies will not be able to collect the debts. Financial difficulties of the debtor, probability that the debtor will enter bankruptcy or financial reorganisation, and default or delinquency in payments are considered objective evidence of impairment. The amount of the impairment loss is the receivable carrying amount compared to the present value of estimated future cash flows, discounted at the original effective interest rate. Cash flows relating to short-term receivables are not discounted if the effect of discounting is immaterial.

When a trade receivable for which an impairment allowance had been recognised becomes uncollectable in a subsequent period, it is written off against the allowance account. The amount of the impairment loss is recognised in the income statement within other expenses. Subsequent recoveries of amounts previously written off are credited against other expenses in the income statement.

71

Long service leave is paid when leave is taken, with a subsequent reimbursement received from the Coal Mining Industry Long Services Leave Trust Fund. The reimbursement for long service leave is recognised in other receivables and is measured as the present value of expected future reimbursements to be received in respect of services provided by employees up to the reporting date using the projected unit credit valuation method. Expected future reimbursements are discounted using market yields at the reporting date on national government bonds with terms to maturity and currencies that match, as closely as possible, the estimated future cash inflows.

1.4 lnventories

Inventories, including warehouse stores, are valued at the lower of cost and net realisable value.

Coal stock inventory is valued on a weighted average cost of production basis over a rolling 12 month basis. Run of mine inventory includes mining cost less rehandling (picking up and delivering to crusher) costs. Finished goods stock is a combination of mining and coal handling costs. Inventory is recognised as it is loaded onto the stockpile and includes both cash costs and depreciation.

Warehouse stores are valued at their weighted average cost and are subject to regular stock takes (six times annually), and also an annual review of obsolete stock and long term spares. Obsolete stock items are written off to the income statement and long term spares are transferred to property, plant and equipment, and depreciated over their estimated useful lives.

Net realisable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale.

The key assumptions, which require the use of management judgement, are the variables affecting estimated costs to sell and the expected selling price. These key assumptions are reviewed annually.

1.5 Other assets

A prepayment asset, where material, is recognised on the balance sheet for expenditure incurred in advance for the rendering of goods or services at or over some time in the future.

All amounts are recognised exclusive of any GST that may be applicable to the underlying good or service.

A prepayment asset is not recognised on expenditure incurred in acquiring inventories, property, plant and equipment, or intangible assets.

1.6 Income tax

Current tax assets and liabilities for the current and prior reporting periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted by the balance sheet date.

Deferred income. tax is provided on all temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

72

Deferred income tax liabilities are recognised for all taxable temporary differences, except where the deferred income tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

In respect of taxable temporary differences associated with investments in subsidiaries deferred tax liabilities are recognised, other than where the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred income tax assets are recognised for all deductible temporary differences, carry- forward of unused tax assets and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry- forward of unused tax assets and unused tax losses can be utilised, except:

(a) where the deferred income tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and

(b) in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are only recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.

The carrying amount of deferred income tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilised.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the balance sheet date.

Income taxes relating to items recognised directly in equity are recognised in equity and not in the income statement.

Deferred tax assets and deferred tax liabilities are offset only if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred tax assets and liabilities relate to the same taxable entity and the same taxation authority.

1.7 Other taxes

Assets are recogrised net of the amount of goods and services tax (‘GST’), except:

(a) where the GST incurred on a purchase of goods and services is not recoverable from the taxation authority, in which case the GST is recognised as part of the cost of acquisition of the asset or as part of the expense item as applicable; and

(b) receivables and payables which are stated with the amount of GST included.

The net amount of GST recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the balance sheet.

1.8 Property, plant and equipment

Property, plant and equipment is stated at cost less accumulated depreciation and any accumulated impairment losses.

73

Such costs include the cost of replacing parts that are eligible for capitalisation when the cost of replacing the parts is incurred. Similarly, when each major inspection is performed, its cost is recognised in the carrying amount of the plant and equipment as a replacement only if it is eligible for capitalisation.

Land and buildings are measured at cost less accumulated depreciation on buildings.

Mine infrastructure (including civil works, buildings, water and electricity supply, hard standing areas, etc.) is depreciated over the individual expected useful life of each asset but not to exceed the life of the mine.

Most mobile equipment is depreciated over an estimated life of the machine expressed in operating hours. Where appropriate, consideration is given to the application of a units of production depreciation method to best reflect the expected pattern of consumption. The smaller items (for example, light vehicles, lighting plant, and pumps) are depreciated via the straight line method over a total estimated life in years.

Other fixed assets (for example, tooling, furniture, miscellaneous equipment) are to be depreciated via the straight line method over a total estimated life in years, but not to exceed the life of the mine.

Useful lives and residual value of property, plant and equipment are reviewed annually. Judgement is applied in determining the useful lives of property, plant and equipment. These judgements are supported by consultation with internal technical experts. Any reassessment of useful lives and residual value in a particular year will affect depreciation and amortisation expense (either increasing or decreasing) from the date of reassessment through to the end of the reassessed useful life for both the current and future years.

Adjustments to the carrying amount of property plant and equipment are only recognised where impairment relates to a separately identifiable asset on the fixed asset register (i.e. individual asset damage).

An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected to arise from the continued use of the asset.

Any gain or loss arising on de-recognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is included in the income statement in the period the item is derecognised.

The director’s coal reserve valuation is amortised over the recoverable coal reserves. Where recoverable coal reserves are revised (other than through the mining of coal), the rate at which the director’s reserve valuation is amortised is revised so that the remaining valuation is written-off over the remaining reserves.

Similarly, mine development costs are amortised over the recoverable coal reserves that the costs were incurred to develop. Where recoverable coal reserves in an area are revised (other than through the mining of coal), the rate at which the development costs are amortised is revised so that the costs are written-off over the remaining reserves. Changes in depreciation estimates resulting from the revision of reserves are accounted for in the income statement prospectively.

Exploration and evaluation expenditure incurred by or on behalf of the Companies is accumulated separately for each area of interest. Such expenditure comprises net direct costs and an appropriate portion of related overhead expenditure, but does not include general overheads or administrative expenditure not having a specific nexus with a particular area of interest.

74

Exploration expenditure for each area of interest is expensed as incurred, except that it may be carried forward provided that one of the following conditions is met:

(a) such costs are expected to be recouped through successful development and exploitation of the area of interest or, alternatively, by its sale; or

(b) exploration activities in the area of interest have not, at balance date reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves.

Exploration expenditure which no longer satisfies the above policy is written off. When an area of interest is abandoned, any expenditure carried forward in respect of that area of interest is written off in the year in which the decision to abandon is made.

Expenditure is not carried forward in respect of any area of interest unless the Companies right of tenure to that area of interest are current. Amortisation is not charged on areas under development, pending commencement of production.

1.9 Trade and other payables

Trade payables and other payables are carried at amortised cost and represent liabilities for goods and services provided to the Companies prior to the end of the financial year that are unpaid and arise when the Companies becomes obliged to make future payments in respect of the purchase of these goods and services. Trade payable are non-interest bearing and are normally settled on terms up to 60 days.

1.10 Internal Funds Management System (IFMS)

Wesfarmers operates an IFMS, where there is one consolidated bank account for Wesfarmers and each entity within the group makes payments and deposits through this system utilising Wesfarmers’ bank account. Each entity’s net IFMS balance effectively represents an intercompany receivable or payable for transactions processed through this system. It will therefore be necessary for the Buyer to arrange new banking facilities.

1.11 Provisions

Provisions are recognised when the Companies have a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.

If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability to the extent they are not already reflected in the cash flows.

Where discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost.

1.12 Mine and plant rehabilitation

Provision is made for the Companies’ estimated liability under specific legislative requirements and the conditions of its licences and leases for future costs (at discounted amounts) expected to be incurred rehabilitating areas of operation. The liability includes the cost of reclamation of the site using existing technology, including plant removal and landfill costs. This provision is recognised immediately at the time of disturbance or when development of the asset occurs.

75

1.13 Employee leave benefits

(a) Wages, salaries and annual leave

Liabilities for wages and salaries, including non-monetary benefits and annual leave expected to be settled within 12 months of the reporting date, are recognised in provisions and other payables in respect of employees’ services up to the reporting date. They are measured at the amounts expected to be paid when the liabilities are settled.

(b) 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 valuation method. Consideration is given to expected future wage and salary levels, experience of employee departures, and periods of service. Expected future payments are discounted using market yields at the reporting date on national government bonds with terms to maturity and currencies that match, as closely as possible, the estimated future cash outflows.

Expenses which are consequential to the employment of the employees (for example, payroll tax associated with employee entitlements) are also recognised as a liability and included in the amount for employee entitlements.

(c) Sick leave

The liability for vesting sick leave is recognised in the provision for employee benefits and includes associated payroll on-costs (e.g. payroll tax) that are expected to be paid in respect of services provided by employees up to the reporting date. Consideration is given to the entitlement under the Collective Agreement, expected future wage levels and experience of employee departures. Expected future payments are discounted using market yields at the reporting date on national government bonds. Non vesting sick leave is recognised in the income statement as and when an employee takes leave and it is measured at the rates paid or payable.

1.14 Other matters

(a) No provision for transaction costs or restructuring costs should be included.

(b) Any adjustments that the Buyer is required to make to the carrying values of the assets and liabilities under AASB 3 (i.e. fair value adjustments) must not be taken into account or otherwise reflected.

(c) No revaluations or reversals of impairments are to be carried out prior to Completion.

(d) No onerous contract testing in accordance with AASB 137 will be carried out.

(e) All employee leave benefits of each employee of each Company must be included.

(f) Any retention incentive in respect of each relevant Company employee which is payable by a Company at Completion must be included in the Completion Balance Sheet and form part of the Completion Working Capital Amount.
