1Accounting Policies

Basis of measurement and preparation of accounts
The financial statements are prepared under the historical cost convention.
Compliance with accounting standards
The financial statements are prepared in accordance with applicable United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), which have been applied consistently (except as otherwise stated).

Turnover policy
Turnover represents amounts receivable for goods and services net of VAT and trade discounts.

Tangible assets depreciation policy
Tangible fixed assets are stated at cost less depreciation. Depreciation is provided at rates calculated to write off the cost less estimated residual value of each asset over its expected useful life as follows:
Plant and machinery 25% of written down value
Computer equipment 25% of written down value

Other accounting policies
Leasing and hire purchase commitments
Assets obtained under hire purchase contracts and finance leases are capitalised as tangible assets and depreciated over the shorter of the lease term and their useful lives. Obligations under such agreements are included in creditors net of the financial 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 payable under operating leases are charged against income on a straight line basis over the lease of the term.
Stock and work in progress
Work in progress is valued at the lower of cost and net realisable value.
