Expenditure is recognised in respect of goods and services received
when supplied in accordance with contractual terms. Provision is
made when an obligation exists for a future liability in respect of a
past event and where the amount of the obligation can be reliably
estimated. Manufacturing start-up costs between validation and the
achievement of normal production are expensed as incurred.
Advertising and promotion expenditure is charged to the income
statement as incurred. Shipment costs on inter-company transfers
are charged to cost of sales; distribution costs on sales to customers
are included in selling, general and administrative expenditure.
