8 Final pay: general
1 Subject to regulations 9 (final pay: reserve forces, maternity leave, etc.) to 11 (final pay: fluctuating emoluments), a member’s final pay for an employment is his pensionable pay for as much of the final pay period as he is entitled to count as active membership in relation to that employment.
2 A member’s final pay period is—
(a) the year ending with the day on which he stops being an active member; or
(b) either of the 2 immediately preceding years ending with a day that is the anniversary of the last day he was an active member, if this results in a higher figure.
3 In the case of part-time employment, the final pay is the pensionable pay that would have been paid for a single comparable whole-time employment.
4 Any reduction or suspension of a member’s pay during the final pay period because of his absence from work owing to illness or injury must be disregarded.
