5 CFR 1605.21 - Plan-paid breakage and other corrections.
(1) Subject to paragraph (a)(3) of this section, if, because of an error committed by the Board or the TSP record keeper, a participant's account is not credited or charged with the investment gains or losses the account have received had the error not occurred, the account will be credited accordingly.
(i) Delay in crediting contributions or other money to a participant's account;
(ii) Improper issuance of a loan or withdrawal payment to a participant or beneficiary which requires the money to be restored to the participant's account; and
(iii) Investment of all or part of a participant's account in the wrong investment fund(s).
(4) If the participant continued to have a TSP account, or would have continued to have a TSP account but for the Board or TSP record keeper's error, the TSP will compute gains or losses under paragraph (a)(1) of this section for the relevant period based upon the investment funds in which the affected money would have been invested had the error not occurred. If the participant did not have, and should not have had, a TSP account during this period, then the TSP will use the G Fund rate of return for the relevant period and return the money to the participant.
(b)Other corrections. The Executive Director may, in his discretion and consistent with the requirements of applicable law, correct any other errors not specifically addressed in this section, including payment of breakage, if the Executive Director determines that the correction would serve the interests of justice and fairness and equity among all participants of the TSP.
