The Board cannot sustain a request for reconsideration unless the Board finds that—
The data used in the actuarial report required by § 841.416 are sufficient and reliable;
The assumptions used in the actuarial report required by § 841.416 are justified; and
The difference in the supplemental liability amount is at least 2 percent of the present value of future benefits calculated in OPM's computation of the supplemental liability.
If the Board sustains a request for reconsideration of the supplemental liability, OPM will recompute the supplemental liability according to the economic and demographic assumptions recommended by the Board.
