PSI20.1.12 - Funding and Surpluses: Funding General - Final Salary Schemes


(This archived guidance relates to HMRC discretionary practice before the 6th April 2006. For current guidance on Registered Pension Schemes see the Registered Pension Schemes Manual)

The actuary’s main concern on final salary (defined benefits) schemes is to ensure that the contributions are set at a level which is sufficient to provide the promised benefits when they fall due. To do this the actuary makes a series of estimates which are commonly called actuarial assumptions. The main assumptions are:
  1. the life expectancy of the scheme members (see PSI20.1.20-23),
  2. the likely career development and final salaries of the members (see PSI20.1.26-27),
  3. the amount of any increases to pensions in payment (see PSI20.1.30-31),
  4. the return on the scheme’s investments (the “investment return”) (see PSI20.1.33), and
  5. the effect that inflation will have on the real value of the members’ salaries and the scheme’s investment income (see PSI20.1.34-35).
