Sec. 1605.4  Back pay awards and other retroactive pay adjustments.

    (a) Participant not employed. The following rules apply to 
participants who receive a back pay award or other retroactive pay 
adjustment for a period during which the participant was separated from 
Government employment:
    (1) If the participant is reinstated to Government employment, then 
immediately upon reinstatement the employing agency must give the 
participant the opportunity to submit a contribution election form (Form 
TSP-1) to make current contributions. The effective date of the form 
will be the first day of the first full pay period in the most recent 
TSP election period. If the participant is reinstated during a TSP open 
season but before the election period, he or she can also submit an 
election form that will become effective the first day of the first full 
pay period in the following election period.
    (2) The participant must be given the following options for electing 
makeup contributions:
    (i) If the participant had a valid contribution election form (Form 
TSP-1) on file when he or she separated, upon the participant's 
reinstatement to Government employment that election form will be 
reinstated for purposes of makeup contributions, unless a new contri 
bution election form is submitted to terminate all makeup contributions 
or those contributions that would have been made from the date of

[[Page 193]]

separation through the end of the open season that occurred immediately 
after the separation.
    (ii) Instead of making contributions for the period of separation 
under the reinstated contribution election form, the participant may 
submit a new election form for any open season that occurred during the 
period of separation. However, the investment allocation on each Form 
TSP-1 for the period of separation must be the same as the investment 
allocation on the current Form TSP-1.
    (3) Lost earnings will be calculated and credited to the 
participant's account, in accordance with 5 CFR Part 1606, using the 
rates of return for the G Fund, unless the participant submitted one or 
more interfund transfer requests during the period of separation. In the 
case of interfund transfer requests, the earnings will be calculated 
using the G Fund rates of return until the first interfund transfer was 
processed. The contribution that is subject to lost earnings will be 
moved to the investment fund(s) the participant requested and lost 
earnings will be calculated based on the earnings for that fund(s). The 
amount of lost earnings calculated will be posted to the investment 
fund(s) to which the contribution was moved by the interfund transfer. 
If there were no interfund transfers processed during the lost earnings 
calculation period, the amount of lost earnings calculated will be 
posted to the employee's G Fund account.
    (b) Participant employed. The following rules apply to participants 
who receive a back pay award or other retroactive pay adjustment for a 
period during which the participant was not separated from Government 
employment:
    (1) The participant will only be entitled to makeup contributions 
for the period covered by the back pay award or retroactive pay 
adjustment if, for that period, the participant had designated a 
percentage of basic pay to be contributed to the TSP or had designated a 
dollar amount of contributions each pay period which had to be reduced 
(because of an applicable 5% or 10% limit on contributions per pay 
period) as a result of the reduction in pay that is made up by the back 
pay award or other retroactive pay adjustment.
    (2) The employing agency must compute the amount of additional 
employee contributions that would have been contributed to the 
participant's account had the action leading to the back pay award or 
other retroactive pay adjustment not occurred. The employing agency must 
also compute the amount of agency matching contributions and agency 
automatic (1%) contributions that would have been payable had that 
action not occurred.
    (c)(1) Makeup employee contributions required under paragraphs (a) 
and (b) of this section must be computed before the back pay or other 
retroactive pay adjustment is made. The makeup employee contributions 
must be deducted from the back pay or other retroactive pay adjustment 
and contributed to the TSP. However, contributions must not be made that 
would cause the participant to exceed the annual contribution limit(s) 
contained in sections 402(g) and 415 of the Internal Revenue Code 
(I.R.C.) (26 U.S.C. 402(g) and 415) for the prior year(s) with respect 
to which the contributions are being made, taking into consideration the 
TSP contributions already made in (or with respect to) that year.
    (2)(i) If employee contributions are deducted from a back pay award 
or other retroactive pay adjustment, the employing agency will be 
responsible for contributing the associated agency matching 
contributions at the same time the employee contributions are made. 
Regardless of whether a participant elects makeup employee 
contributions, the employing agency must make, in a lump sum payment, 
all appropriate agency automatic (1%) contributions associated with the 
back pay award or other retroactive pay adjustment.
    (ii) Any makeup contributions (both employee and employer) 
associated with a back pay award or other retroactive pay adjustment 
must be reported by the employing agency for investment among the TSP 
investment fund(s) using the participant's investment fund election in 
effect at the time the makeup contributions are made. If no such 
election is on file, the

[[Page 194]]

contributions must be reported by the employing agency for investment in 
the G Fund.
    (d) The employing agency must pay any lost earnings on TSP 
contributions derived from back pay awards or other retroactive pay 
adjustments that are required to be paid under 5 CFR Part 1606.
    (e) If a participant has withdrawn his or her TSP account other than 
by purchasing an annuity, and the separation from Government employment 
upon which the withdrawal was based is reversed, resulting in 
reinstatement of the participant without a break in service, then the 
participant will have the option, which must be exercised by notice to 
the Board within 90 days of reinstatement, to restore to his or her TSP 
account the amount withdrawn. The right to restore the withdrawn funds 
will expire if the notice is not provided to the Board within 90 days of 
reinstatement. No earnings will be paid on any restored funds.
