The estimated amounts of contributions expected to be paid to the schemes during the financial year commencing 1 January 2012 in respect of the ongoing<br />
accrual of benefits should be approximately £10m <strong>and</strong> it is anticipated that these will remain at a similar level in the medium term subject to changes in<br />
financial conditions. Additional contributions of approximately £35m will also be made in 2012 in respect of the deficit in the schemes.<br />
IAS 19 specifies that pension liabilities should be discounted at appropriate high quality corporate bond rates. The directors consider that it is appropriate to<br />
apply the average of the yields on those AA corporate bonds which most closely approximate to the timescale of the liability profile of the schemes <strong>and</strong><br />
have therefore used such a rate, being 4.95%, in respect of the UK schemes at 31 December <strong>2011</strong> (5.5% at 31 December 2010). The effect of a 0.1%<br />
movement in the discount rate applicable in the UK is to alter reported liabilities (before associated deferred tax) by approximately £30m.<br />
Liability calculations are also impacted heavily by the mortality projections included in the actuarial assumptions. The weighted average life expectancy of a<br />
male member of the UK schemes currently aged 65 has been assumed as 21 years. The weighted average life expectancy at 65 of a male currently aged 52<br />
has been assumed as 22 years. The directors consider, on actuarial advice, these assumptions to be appropriate to the profile of the membership of the<br />
schemes. The effect of a one year change in this UK life expectancy assumption is to alter reported liabilities (before associated deferred tax) by<br />
approximately £78m.<br />
Pension obligations in respect of deferred members increase in line with inflation. Increases in salaries <strong>and</strong> increases in pensions-in-payment generally move<br />
in line with inflation. Inflation is therefore an important assumption in the calculation of defined retirement benefit liabilities. The effect of a 0.1% movement<br />
in the rate of inflation assumption applicable in the UK is to alter reported liabilities (before associated deferred tax) by approximately £16m.<br />
