# §225.55. Recomputation to use a new or different PIA formula.

- (a) **Description—**
  - (1) **New computation formula.** If a new formula for computing or recomputing PIA's is enacted into law and the annuitant is eligible for the recomputation, the Board will recompute the PIA under the new formula.
  - (2) **Recomputation under different formula.** In some cases, a PIA may be recomputed under a computation formula different from the formula used in the computation (or earlier recomputation) of the PIA. The annuitant must be eligible for a computation or recomputation under the different formula.
- (b) **Effective date of recomputation—**
  - (1) **New computation formula.** A PIA recomputed under a newly enacted formula is effective with the month as directed in the legislation that establishes the new formula. The new PIA formula applies when it produces a PIA that is higher than the amount on which the existing annuity is based.
  - (2) **Different computation formula.** A PIA recomputed under a different formula is effective with the first month that the different formula produces a PIA that is higher than the PIA on which the existing annuity is based.
