PART 9Annual increase in periodic compensation

Determination of indexed proportion

29.  In any case where it is unclear whether the pension compensation credit or any part of it is derived from rights of the transferor relating to pensionable service (whether actual or notional) occurring—

(a)before 6th April 1997, or

(b)on or after 6th April 1997,

the Board may determine as best as it is able, having regard to the admissible rules of the scheme and all the circumstances of the case, how much of the service or notional service of the transferor should be treated for the purposes of paragraph 17 of Schedule 4 (annual increase in periodic compensation) as having occurred before 6th April 1997 and how much should be treated as having occurred on or after that date.
