The calculations and formulae in this guidance contain adjustments to reflect the inflationary increases on a member's Guaranteed Minimum Pension (GMP), which have historically been the responsibility of the State Scheme after GMP Payment Age.

However, following the requirement to equalise GMPs, from 6 March 2020, GMP adjustment factors should no longer be applied in calculations for members who reach State Pension age (SPA) on or after 6 April 2016.

The cohorts of members who will be affected by this change will be:

• Males with a date of birth on or after 6 April 1951 and an accrued GMP
• Females with a date of birth on or after 6 April 1953 and an accrued GMP

For members with an accrued GMP in the cohorts listed above, calculations of cash equivalents of member benefits should be undertaken using the methodology set out in this guidance note but with any GMP (pre or post 1988) set to zero. (Debits to a member's GMP following a divorce still need to be determined however.)

For the majority of calculations for these cohorts of members, not applying the GMP adjustment factors will slightly increase the total transfer value.
