Pensions and other post-employment benefits
The costs of providing pensions under defined benefit schemes are calculated using the projected unit credit method and spread over the period during which benefit is expected to be derived from the employees’ services, consistent with the advice of qualified actuaries. Pension obligations are measured as the present value of estimated future cash flows discounted at rates reflecting the yields of high quality corporate bonds. Pension scheme assets are measured at fair value at the balance sheet date.
The costs of other post-employment liabilities are calculated in a similar way to defined benefit pension schemes and spread over the period during which benefit is expected to be derived from the employees’ services, in accordance with the advice of qualified actuaries.
Actuarial gains and losses and the effect of changes in actuarial assumptions, are recognised in the statement of comprehensive income in the year in which they arise.
The Group’s contributions to defined contribution plans are charged to the income statement as incurred.
