Goodwill is the difference between amounts paid on the acquisition of a business and the fair value of the separable net assets. It is amortised to profit and loss account over its estimated economic life of 20 years on a straight line basis.

Tangible fixed assets are measured at cost less accumulated depreciation and any accumulated impairment losses. Depreciation is provided at rates calculated to write off the cost of the fixed assets, less their estimated residual value, over their expected useful lives on the following bases:

Assets obtained under hire purchase contracts and finance leases are capitalised as tangible fixed assets. Assets acquired under finance leases are depreciated over the shorter of the lease term and their useful lives. Assets acquired under hire purchase contracts are depreciated over their useful lives. Finance leases are those where substantially all of the benefits and risks of ownership are assumed by the company. Obligations under such agreements are included in the creditors net of the finance charge allocated to future periods. The finance element of the rental payment is charged to the profit and loss account so as to produce a constant periodic rate of charge on the net obligation outstanding in each period.

Rentals applicable to operating leases where substantially all of the benefits and risks of ownership remain with the lessor are charged to profit and loss account as incurred.

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell . Goods in transit are accounted for in closing stocks, as ownership of goods are recognised.
