The group has a centralised treasury operation which has remained following the progressive devolution of the group's operations. Its primary role is to manage liquidity, funding, investment and the group's financial risk, including risk from volatility in currency and interest rates and counterparty credit risk. The treasury operation is not a profit centre and the objective is to manage risk at optimum cost.
The Board sets the treasury department's policy and its activities are subject to a set of controls commensurate with the magnitude of the borrowings and investments under its management. Counterparty credit risk is closely monitored and managed within controls set by the Board. Derivative instruments, including forward foreign exchange contracts, are entered into for hedging purposes only.
We have set out further details on this topic and on our capital resources and foreign currency exposure in note 36 to the financial statements in compliance with FRS 13.
