5 CFR 842.407 : Administrative Personnel (§ 1.1 To Parts 10003-10049) — (Parts 700-714 To Parts 1002-1199) — Office Of Personnel Management (Continued) (Parts 700-714 To Parts 1002-1199) — Civil Service Regulations (Continued) (Parts 700-714 To Part 990) — Federal Employees Retirement System - Basic Annuity (§ 842.101 To § 842.1009) — Computations (§ 842.401 To § 842.407) — Proration of annuity for part-time service.

The annuity of an employee whose service includes part-time service is computed in accordance with § 842.403, using the average pay based on the annual rate of basic pay for full-time service. This amount is then multiplied by the proration factor. The result is the annual rate of annuity before reductions for retirement before age 62, survivor benefits, or the reduction for an alternative form of annuity required by § 842.706.
