Computation of annuities for part-time service.
The computational method in this section shall be used to determine the annuity for an employee who has part-time service on or after April 7, 1986.
In this section—
Full-time service means any actual service in which the employee is schedule to work the number of hours and days required by the administrative workweek for his or her grade or class (normally 40 hours).
Intermittent service means any actual service performed with no prescheduled regular tour of duty.
Part-time service means any actual service performed on a less than full-time basis, by an individual whose appointment describes a regularly scheduled tour of duty, and any period of time credited as non pay status time under 5 U.S.C. 8332(f), which follows a period of part-time service without any intervening period of actual service other than part-time service. This definition is not limited to part-time career employment because it includes part-time temporary employment as well.
Post-April 6, 1986 average pay means the largest annual rate resulting from averaging, over any period of 3 consecutive years of creditable service, the annual rate of basic pay that would be payable for full-time service by an employee during that period, with each rate weighted by the time it was in effect, except that for periods of service before April 7, 1986, the actual rate of basic pay based on the employee's established tour of duty, if different, is used in the computation. The rates of pay included in the computation for intermittent service or temporary service performed on a full-time basis are the actual rates of basic pay during those periods of creditable service.
Pre-April 7, 1986, average pay means the largest annual rate resulting from averaging, over any period of 3 consecutive years of creditable service, an employee's actual rates of basic pay during that period, with each rate weighted by the time it was in effect.
Proration factor means a fraction expressed as a percentage rounded to the nearest percent. The numerator is the sum of the number of hours the employee actually worked during part-time service, and the denominator is the sum of the number of hours that a full-time employee would be schedule to work during the same period of service included in the numerator. If an employee has creditable service in addition to part-time service (full-time service, intermittent service, or temporary service performed on a full-time basis), such service must be included in the numerator and denominator of the fraction. In general, this is done by including the number of days of such intermittent service, multiplied by 8, and the number of weeks of such temporary service or full-time service, multiplied by 40 in both the numerator and the denominator. The additional credit for unused sick leave under 5 U.S.C. 8339(m) is not included in the fraction.
Temporary service means service under an appointment limited to one year or less, exclusive of intermittent service.
(c) Pre-April 7, 1986, basic annuity.
The partial annuity for pre-April 7, 1986, service is computed in accordance with 5 U.S.C. 8339 using the pre-April 7, 1986, average pay and length of service (increased by the unused sick leave credit at time of retirement) prior to April 7, 1986.
(d) Post-April 6, 1986, basic annuity.
The partial annuity for post-April 6, 1986, service is computed in accordance with 5 U.S.C. 8339 using the post-April 6, 1986, average pay and length of service after April 6, 1986. This amount is then multiplied by the proration factor.
(e) Combined basic annuity.
The combined basic annuity is equal to the sum of the partial annuity amounts computed under paragraphs (c) and (d). This amount is the yearly rate of annuity (on which the monthly rate is based) before reductions for retirement before age 55; pre-October 1, 1982, nondeduction service and survivor benefits; or the reduction for an alternative annuity under section 204 of Pub. L 99-335.
The use of the post-April 6, 1986, average pay is limited to the purposes stated in this section. It may not be used as the basis for computing:
