# §831.1742. Computation of composite annuity at final retirement.

- (a) Subject to the adjustment described in [paragraph (c)](#c) of this section, a phased retiree's composite retirement annuity at final retirement equals the sum obtained by adding—
  - (1) The amount computed under [§ 831.1741(a)](/cfr/5/831.1741.md?p=a) without adjustment under § [831.1741(b)](/cfr/5/831.1741.md?p=b) and [(c)](/cfr/5/831.1741.md?p=c), increased by cost-of-living adjustments under [§ 831.1743(c)](/cfr/5/831.1743.md?p=c); and
  - (2) **The “fully retired phased component” computed under paragraph (b) of this section.**
- (b)
  - (1) Subject to the requirements described in paragraphs [(b)(2)](#b-2) and [(b)(3)](#b-3) of this section, a “fully retired phased component” equals the product obtained by multiplying—
    - (i) The working percentage; by
    - (ii) The amount of an annuity computed under [5 U.S.C. 8339](/usc/5/8339.md) that would have been payable at the time of full retirement if the individual had not elected phased retirement status and as if the individual was employed on a full-time basis in the position occupied during the phased retirement period and before any reduction for survivor annuity.
  - (2) In applying [paragraph (b)(1)(ii)](#b-1-ii) of this section, the individual must be deemed to have a full-time schedule during the period of phased retirement. The deemed full-time schedule will consist of five 8-hour workdays each workweek, resulting in a 40-hour workweek. In determining the individual's deemed rate of basic pay during phased retirement, only basic pay for hours within the deemed full-time schedule will be considered, consistent with the definition of “full-time” in [§ 831.1702](/cfr/5/831.1702.md). Any premium pay creditable as basic pay for retirement purposes for overtime work or hours outside the full-time schedule that an employee was receiving before phased retirement, such as standby duty pay under [5 U.S.C. 5545(c)(1)](/usc/5/5545.md?p=c-1) or customs officer overtime pay under [19 U.S.C. 267(a)](/usc/19/267.md?p=a), may not be considered in determining a phased retiree's deemed rate of basic pay during phased retirement.
  - (3) **In computing the annuity amount under paragraph (b)(1) of this section—**
    - (i) The amount of unused sick leave equals the result of dividing the days of unused sick leave to the individual's credit at separation for full retirement by the working percentage; and
    - (ii) The reduction for any unpaid deposit for non-deduction service performed before October 1, 1982, is based on the amount of unpaid deposit, with interest computed to the commencing date of the composite annuity.
- (c) The composite retirement annuity computed under [paragraph (a)](#a) of this section is adjusted by applying any reduction for any survivor annuity benefit.
- (d) The monthly installment derived from a composite retirement annuity computed under [paragraph (a)](#a) of this section and adjusted under [paragraph (c)](#c) is adjusted by any—
  - (1) Actuarial reduction applied to the phased retirement annuity under [§ 831.1741(b)](/cfr/5/831.1741.md?p=b), increased by cost-of-living adjustments under [§ 831.1743(d)](/cfr/5/831.1743.md?p=d); and
  - (2) Offset under [§ 831.1005](/cfr/5/831.1005.md) (i.e., the offset based on all service, including service during the phased retirement period, performed by the individual that was subject to mandatory Social Security coverage).
