ACCOUNTING POLICY

Provisions

Provisions are recognised when AGL has a present obligation (legal or constructive) as a result of a past event, it is probable that AGL will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. The unwinding of the discount is recognised in profit or loss as part of finance costs.

Onerous contracts

A provision for onerous contracts is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract.

Environmental restoration

The provision for future restoration costs is the best estimate of the present value of the expenditure required to settle the restoration obligation at the end of the reporting period, based on current legal requirements and current technology. Future restoration costs are reviewed periodically and any changes are reflected in the provision at the end of each reporting period.

The initial estimate of the environmental restoration provision relating to exploration, development and production facilities is capitalised into the cost of the related asset and depreciated/ amortised on the same basis as the related asset. Changes in the estimate of the provision for environmental restoration are treated in the same manner, except that the unwinding of the effect of discounting on the provision is recognised as a finance cost rather than being capitalised into the cost of the related asset.

Restructuring

A restructuring provision is recognised when AGL has developed a detailed formal plan for the restructuring and has raised a valid expectation in those affected that it will carry out the restructuring by starting to implement the plan or announcing its main features to those affected by it. Future operating losses are not provided for.

Employee benefits

A liability is recognised for benefits accruing to employees in respect of wages and salaries, annual leave, long service leave and sick leave when it is probable that settlement will be required and they are capable of being measured reliably.

Liabilities recognised in respect of short-term employee benefits are measured at their nominal values using the remuneration rate expected to apply at the time of settlement.

Liabilities recognised in respect of long-term employee benefits are measured as the present value of the estimated future cash outflows to be made by AGL in respect of services provided by employees up to the end of the reporting period.

CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS

Provision for environmental restoration

AGL estimates the future removal and restoration costs of electricity generation assets, oil and gas production facilities, wells, pipelines and related assets at the time of installation of the assets. In most instances, removal of these assets will occur many years into the future. The calculation of this provision requires management to make assumptions regarding the removal date, application of environmental legislation, the extent of restoration activities required and available technologies.
