Statement of Significant Accounting Policies
For the year ended 31 March 2005
Land and buildings are revalued on a cyclical basis at no more than 5 yearly intervals.
Any revaluation surplus arising on the revaluation of a class of property, plant or equipment is transferred directly to the asset revaluation reserve. A revaluation deficit in excess of the asset revaluation reserve balance for the class of property, plant or equipment is recognised in the Statement of Financial Performance in the period it arises. Revaluation surpluses which reverse previous revaluation deficits recognised in the Statement of Financial Performance are recognised as revenue in the Statement of Financial Performance.
Disposal of Property, Plant and Equipment
When an item of property, plant or equipment is disposed of, any gain or loss is recognised in the Statement of Financial Performance and is calculated as the difference between the sale price and the carrying value of the asset.
The carrying values of property, plant and equipment do not exceed their estimated recoverable value. On disposal of an item of property, plant or equipment, any revaluation surplus in respect of that class of asset is reduced or increased by the amount applicable to that item.
b. Depreciation
Depreciation is provided on a straight line basis on all tangible items of property, plant and equipment other than freehold land, at rates calculated to allocate the assets cost or valuation less any residual value, over their estimated useful lives.
