The Board's error correction regulations (5 CFR 1605 of chapter VI) generally allow you to increase your TSP account through a schedule of make-up contributions to replace the missed employee contributions. In addition, the FERCCA allows certain employees who have completed a schedule of make-up contributions, or who plan to schedule make-up contributions, to receive lost earnings on those contributions under certain circumstances. Employees are (and have been) entitled to lost earnings on the make-up agency contributions they receive as a result of the correction of an agency error.

If you made contributions to the TSP after your qualifying retirement coverage error was previously corrected, OPM will compute the lost earnings on your make-up contributions to the TSP under the following circumstances:

(a) Lost earnings will generally be computed in accordance with the Board's lost earnings regulations (5 CFR 1606 of chapter VI). However, the FERCCA states that OPM may compute the lost earnings in an alternative manner if such a computation is not administratively feasible. The alternative manner will yield an amount that is as close as practicable to the amount computed under 5 CFR 1606 of chapter VI.

(b) Your employer is required to submit to OPM all information required to compute the amount of lost earnings.

(a) Yes. If the TSP account is not withdrawn, the lost earnings are paid to the account.

(b) If there is no TSP account at the time the lost earnings are payable, you or your survivors will receive the payment directly.
