## AEGON UK 

AEGON UK operates a defined benefit pension scheme providing benefits for staff based on final pensionable salary. The assets of the scheme are held under trust separately from those of the Group. The assets of the scheme are held in policies affected with Scottish Equitable plc. The scheme is closed to new entrants. Under IAS 19, the defined benefit plan has a deficit of EUR 247 million at December 31, 2010 (2009: EUR 339 million). 

Assumptions used to determine benefit obligations at year-end: 

For each asset class, a long-term return assumption is derived taking into account market conditions, historical returns (both absolute returns and returns relative to other asset classes) and general forecasts for future returns. Government bonds are taken as providing the return with the least risk. The expected long-term rate of return is calculated as a weighted average of these assumed rates, taking account of the long-term strategic allocation of funds across the different classes adopted by the trustees of the scheme.
