5. Finance income and charges

Accounting policies
Net interest includes interest income and charges in respect of financial instruments and the results of hedging transactions used to manage interest rate risk.
Finance charges directly attributable to the acquisition, construction or production of a qualifying asset, being an asset that necessarily takes a substantial period of time to get ready for its intended use or sale, are added to the cost of that asset. Borrowing costs which are not capitalised are recognised in the income statement using the effective interest method. All other finance charges are recognised primarily in the income statement in the year in which they are incurred.
Net other finance charges include items in respect of post employment plans, the discount unwind of long-term obligations and hyperinflation charges. The results of operations in hyperinflationary economies are adjusted to reflect the changes in the purchasing power of the local currency of the entity before being translated to sterling.
The impact of derivatives, excluding cash flow hedges that are in respect of commodity price risk management or those that are used to hedge the currency risk of highly probable future currency cash flows, is included in interest income or interest charge.
