STATEMENT OF ACCOUNTING POLICIES

FOR THE YEAR ENDED 30 JUNE 2009

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

F) PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are tangible assets expected to be used during more than one financial period and include spares held for the servicing of other property, plant and equipment that is owned.

The initial cost of purchased property, plant and equipment is the value of the consideration given to acquire the property, plant and equipment and the value of other directly attributable costs, which have been incurred in bringing the property, plant and equipment to the location and condition necessary for the intended service.

The initial cost of self-constructed property, plant and equipment includes the cost of all materials used in construction, direct labour on the project, financing costs that are attributable to the project, costs of ultimately dismantling and removing the items and restoring the site on which they are located (where an obligation exists to do so) and an appropriate proportion of the other directly attributable overheads incurred in bringing the items to working condition for their intended use. Financing costs that would have been avoided if the expenditure on qualifying assets had not been made are capitalised while the construction activities are in progress. Costs cease to be capitalised as soon as the property, plant and equipment is ready for productive use and do not include any costs of abnormal waste.

Uninstalled property, plant and equipment are stated at the lower of cost and estimated recoverable amount. Estimated recoverable amount is the greater of the estimated amount from the future use of the property, plant and equipment and its ultimate disposal, and its fair value less costs to sell.

Property, plant and equipment is subsequently measured at cost less accumulated depreciation and impairment losses.

Subsequent expenditure relating to an item of property, plant and equipment is added to its gross carrying amount when such expenditure can be measured reliably and either increases the future economic benefits beyond its existing service potential, or is necessarily incurred to enable future economic benefits to be obtained, and that expenditure would have been included in the initial cost of the item had the expenditure been incurred at that time. The costs of day-to-day servicing of property, plant and equipment are recognised in the income statement as incurred.

G) DEPRECIATION

Depreciation of property, plant and equipment is calculated on a straight line basis so as to expense the cost of the property, plant and equipment, less any expected residual value, to the income statement over its useful economic life.

Depreciation commences when the item of property, plant and equipment is brought into productive use, or when such items become available for use.

H) LEASED ASSETS

Operating leases

Payments made under operating leases, where the lessors effectively retain substantially all the risks and benefits of ownership of the leased property, plant and equipment are recognised in the income statement on a straight-line basis over the lease term. Lease incentives received are recognised as an integral part of the total lease expense over the term of the lease. Property, plant and equipment used under operating leases are not recognised in the balance sheet.

I) PROVISIONS

Employee entitlements

Employee entitlements to salaries and wages, annual leave, long-term leave and other benefits are recognised when they accrue to employees.
