The underlying mortality assumptions for the major schemes are as follows:
United Kingdom
Such is the size and profile of the UK scheme that data on the scheme’s mortality experience is collected and reviewed annually. The key
current year mortality assumptions for the scheme use PA92 (Year of Birth) tables with a plus 2.5 year age adjustment to reflect actual mortality
experience for the scheme together with medium cohort projected improvement in longevity. Using these assumptions a male aged 65 lives for
a further 19.8 years, whilst a male aged 40 is expected to live a further 21 years after retiring at 65. The prior period valuations used the same
mortality assumptions.
Overseas
In the USA, CL2007 tables which were first adopted in 2007 have been used whilst in Germany the RT2005-G tables have again been used.
In the USA the longevity assumption for a male aged 65 is that he lives a further 18.8 years whilst in Germany for a further 17.7 years. The
longevity assumption for a USA male currently aged 40 is that he also lives for a further 18.8 years once attaining 65 years, with the German
equivalent assumption being 17.7 years. These assumptions are based solely on the prescribed tables not on actual GKN experience.
Assumption sensitivity analysis
The impact of a one percentage point movement in the primary assumptions as at 31 December 2008 is set out below:

The 2008 past service cost charge relates to augmentations arising in the UK on redundancy programmes and additional charges in respect of
a continental European subsidiary. The 2007 past service credit of £7 million included a £12 million credit from the impact of changes to retiree
medical benefits in the USA, partly offset by a past service charge of £5 million, £4 million of which is within Restructuring and impairment
charges primarily from further downsizing of a UK business in the Automotive portfolio.
The 2008 settlement/curtailment credit arises from changes to freeze pension benefit entitlements in Driveline and Powder Metallurgy
businesses in the USA. The 2007 settlement/curtailments credit arises from changes in pension regulations in Italy.
