21. In Schedule 2, after paragraph 2 insert—
2A.—(1) This paragraph applies where—
(a)on the first indexation date following the date on which the beneficiary first became entitled to an annual payment; and
(b)on any indexation date following that first indexation date;
the annual rate of annuity which has been or could have been paid to the beneficiary as at that indexation date as a result of the purchase of an annuity with the assets available to discharge the liability of the scheme to, or in respect of, the qualifying member after that liability has or had been determined, is higher as a result of indexation or revaluation than the annual rate determined in accordance with paragraph 2.
(2) Where this paragraph applies, the scheme manager shall redetermine the annual payment payable to that beneficiary with effect from the indexation date.
(3) When redetermining an annual payment under sub-paragraph (2), the actual pension for the purposes of paragraph 3(2) or 4(2) shall be the annual rate of annuity which has been or could have been paid to the beneficiary as at the indexation date as a result of the purchase of an annuity with the assets available to discharge the liability of the scheme to, or in respect of, the qualifying member after that liability has or had been determined, on the basis of, and having regard to, the matters referred to in paragraph 2(3).
(4) In any case where the scheme manager is satisfied, having regard to the information available to it, that it is not possible for it to determine the annual rate of annuity for the purposes of this paragraph, it shall determine that annual rate having regard to such matters as it considers relevant.
(5) Where the scheme manager is satisfied that increases have been, are being, or will be made to the annual rate of annuity, and it considers that those increases are not reasonable, it may determine the annual rate of annuity for the purposes of this paragraph on the basis of the sum which would discharge the liability of the scheme to the beneficiary and of such other matters as it considers relevant.”.
