been invested in a different investment fund had the error not occurred.

(b) Back pay awards and other retroactive pay adjustments. The application of this part 1606, as described in paragraph (a) of this section, includes TSP contributions derived from payments associated with back pay awards or other retroactive pay adjustments that are based on a determination that the employing agency paid a participant less than the full amount of basic pay to which the participant was entitled.

(c) Timing of errors. This part 1606 applies regardless of whether the employing agency error that caused the effects described in paragraph (a) of this section occurred prior to, at, or after the inception of the TSP.

(d) De minimis rules. Notwithstanding paragraphs (a) through (c) of this section or any other provision of this part

1606:

(1) Lost earnings shall not be payable where the amount of money for a source of contributions in a participant's account that is not invested in the Thrift Savings Fund due to an employing agency error, or that is invested in the wrong investment fund due to an employing agency error, is less than one dollar ($1.00) for that source of contributions. Where the employing agency error caused delayed or erroneous contributions for more than one pay period, this paragraph shall apply separately to each pay period involved.

(2) Where the employing agency error caused delay in submission of TSP payment records or loan allotments, lost earnings shall not be payable unless the belated contributions or loan allotments were received by the TSP recordkeeper more than 30 days after the pay date associated with the pay period for which the contributions or loan allotments would have been submitted had the employing agency error not occurred.

(3) For employing agency errors not covered by paragarph (d)(2) of this section, lost earnings shall not be payable unless, as the result of an employing agency error, money was not invested in the Thrift Savings Fund for a period extending more than 30 days after the date it would have been invested had the error not occurred.

(4) The 30-day requirements contained in paragraphs (d)(2) and (d)(3) of this section do not apply where, due to employing agency error, money in a participant's account has been invested in an incorrect investment fund.

(e) Contributions for pre-1987 service. This part does not apply to errors involving employing agency delay in submitting contributions required by 5 U.S.C. 8432(c)(3).

(f) Contributions for service in January through March 1987. Notwithstanding any other provision of this section, lost earnings shall be payable with respect to contributions made pursuant to 5 U.S.C. 8432(c)(1) (B) or (C) if the payment records containing those contributions were received by the TSP recordkeeper after April 30, 1987.

Subpart B-Lost Earnings Attributable to Delayed or Erroneous Contributions

§ 1606.5 Failure to timely make or deduct TSP contributions when participant received pay.

(a) If a participant receives pay, but as the result of an employing agency error all or any part of the Agency Automatic (1%) Contributions associated with that pay to which the participant is entitled are not timely received by the TSP recordkeeper, then the belated contributions shall be subject to lost earnings. In such cases:

(1) The employing agency must, for each pay period involved, submit to the TSP recordkeeper a lost earnings record indicating the pay date for which the belated contribution would have been made had the error not occurred, the investment fund to which the belated contribution would have been deposited had the error not occurred, the amount of the belated contribution, and the pay date for which the belated contribution was actually made. If the belated contribution was actually deposited to an investment fund different from the investment fund to which it would have been deposited had the contribution been timely submitted, then the employing agency must submit an additional lost earnings record indicating the amount of the belated contribution, the pay date for which it was actually made,

the investment fund to which it would have been deposited had the error not occurred, and the investment fund to which it was actually deposited;

(2) The TSP recordkeeper shall compute the amount of lost earnings assoIciated with each lost earnings record submitted by the employing agency pursuant to paragraph (a)(1) of this section, and shall also determine the investment fund or funds in which the belated contributions and associated earnings would currently be invested had the error not occurred. In performing the computation of lost earnings and determining the appropriate investment fund or funds, the TSP recordkeeper must take into consideration any interfund transfers made effective on or after the pay date for which the belated contribution would have been made if the error had not occurred, and which were made effective prior to the end of the month preceding the month during which the lost earnings record is processed. With respect to the period prior to December 31, 1990, the TSP recordkeeper shall also take into account the investment restrictions that were effective under 5 U.S.C. 8438 prior to the effective date of section 3 of the TSPTAA.

(3) Where the lost earnings computed in accordance with paragraph (a)(2) of this section are positive, the TSP recordkeeper shall charge the amount of lost earnings computed to the appropriate employing agency and shall credit that amount to the TSP account of the participant involved. If the lost earnings computed are negative, the amount computed will be removed from the participant's account and used to offset TSP administrative expenses;

(4) The TSP recordkeeper shall adjust the participant's account to reflect the investment funds in which the belated contributions and associated earnings would currently be invested if the error had not occurred, as determined in accordance with paragraph (a)(2) of this section.

(b) If a participant receives pay from which Employee Contributions were properly deducted, but as the result of an employing agency error all or any part of the associated Agency Matching Contributions to which the partici

pant is entitled were not timely received by the TSP recordkeeper, then the belated contributions will be subject to lost earnings. In such cases, the procedures described in paragraphs (a)(1) through (a)(4) of this section will apply to the belated Agency Matching Contributions.

(c) If a participant receives pay from which Employee Contributions were properly deducted, but as the result of an employing agency error all or any part of those Employee Contributions were not timely received by the TSP recordkeeper, the belated contributions will be subject to lost earnings. In such cases, the procedures described in paragraphs (a)(1) through (a)(4) of this section will apply to the belated Employee Contributions.

(d) If a participant receives pay from which Employee Contributions should have been deducted, but as the result of employing agency error all or any part of those deductions were not made, then even if the participant makes up those Employee Contributions pursuant to part 1605, the belated Employee Contributions shall not be subject to lost earnings. However, where the participant does make up the Employee Contributions pursuant to part 1605, the Agency Matching Contributions associated with those belated Employee Contributions (which must be made in accordance with part 1605) will be subject to lost earnings. With respect to such belated Agency Matching Contributions the procedures described in paragraphs (a)(1) through (a)(4) of this section shall apply.

§ 1606.6 Agency delay in paying employee.

Where, as the result of an employing agency error, a participant does not timely receive all or any part of the basic pay to which he or she is entitled, and as a result of that delay in receiving pay all or any part of the Employee Contributions, Agency Automatic (1%) Contributions, or Agency Matching Contributions are not submitted when they would have been had the employing agency error not occurred, all such belated Employee Contributions, Agency Automatic (1%) Contributions, and Agency Matching Contributions shall

1606.7 Contributions to incorrect investment fund.

(a) Where, as the result of an employing agency error, money was deposited to a participant's TSP account in an incorrect investment fund(s), the erroneous contribution shall be subject to lost earnings. In such cases:

(1) The employing agency must submit a lost earnings record indicating the amount of the contributions submitted to the incorrect investment fund(s), the pay date for which it was submitted, the investment fund(s) to which it would have been deposited had the employing agency error not occurred, and the investment fund(s) to which it was actually deposited. If the employing agency has, prior to January 1, 1991 or in contravention of paragraph (b) of this section, removed the contribution from the incorrect investment fund(s) using a negative adjustment record and redeposited the money to the investment fund(s) in which it would have been invested had the error not occurred, the employing agency must also indicate on the lost earnings record when these actions were taken.

(2) The TSP recordkeeper shall compute the amount of lost earnings associated with each lost earnings record submitted by the employing agency pursuant to paragraph (a)(1) of this section, and shall also determine the investment fund or funds in which erroneously invested contributions and associated earnings would currently be invested had the error not occurred. In computing lost earnings and determining the appropriate investment fund or funds, the TSP recordkeeper shall take into consideration any interfund transfers that were made effective on or subsequent to the date erroneous contribution was made, and that were made effective prior to the end of the month preceding the month during which the lost earnings record is processed. With respect to the period prior to December 31, 1990, the TSP recordkeeper shall also take into account the investment restrictions that were effective under 5

U.S.C. 8438 prior to the effective date of section 3 of the TSPTAA;

(3) Where the lost earnings computed in accordance with paragraph (a)(2) of this section are positive, the TSP recordkeeper shall charge the amount of lost earnings computed to the appropriate employing agency and shall credit that amount to the account of the participant involved. If the lost earnings computed are negative, the amount computed shall be removed from the participant's account and used to offset TSP administrative expenses;

(4) The TSP recordkeeper shall adjust the participant's account to reflect the investment funds in which the erroneous contributions and associated earnings would currently be invested had the error not occurred, as determined in accordance with paragraph (a)(2) of this section.

(b) The provisions of part 1605 notwithstanding, effective January 1, 1991, where employing agency error had caused money to be deposited to a TSP account in an incorrect investment fund, the employing agency may not remove the erroneously invested money from the incorrect investment fund(s) using a negative adjustment record and redeposit the money in the investment fund(s) in which it would have been invested had the error not occurred. Rather, the correction must be accomplished solely through the procedures described in paragraph (a) of this section.

§ 1606.8 Late payroll submissions.

(a) Payroll submissions received on or after January 1, 1991. All contributions on payment records contained in a payroll submission received from an employing agency by the TSP Recordkeeper on or after January 1, 1991 and more than 30 days after the pay date associated with the payroll submission (as reported on Form TSP-2, Certification of Transfer of Funds and Journal Voucher), shall be subject to lost earnings, as follows:

(1) The TSP Recordkeeper shall generate a lost earnings record for each payment record contained in the late payroll submission. The lost earnings

records generated by the TSP Recordkeeper shall reflect that the contributions on the payment records should have been made on the pay date associated with the payroll submission, that the contributions should have been deposited to the investment funds(s) indicated on the payment records, and that the contributions were actually made on the date the late payroll submission was processed.

(2) The procedures applicable to lost earnings records submitted by employing agencies set forth in paragraphs (a)(2) through (a)(4) of §1606.5, shall be applied to lost earnings records generated by the TSP Recordkeeper pursuant to paragraph (a)(1) of this section.

(b) Payroll submissions received before January 1, 1991. All contributions on payment records contained in a payroll submission received from an employing agency by the TSP Recordkeeper before January 1, 1991 but more than 30 days after the pay date associated with the payroll submission (as reported on Form TSP-2, Certification of Transfer of Funds and Journal Voucher), shall be subject to lost earnings, as follows:

(1) The employing agency shall, pursuant to instructions provided to employing agencies by the Board, submit to the TSP recordkeeper authorization for lost earnings to be computed on all contributions on the payment records contained in the payroll submission;

(2) The procedures set forth in paragraphs (a)(1) and (a)(2) of this section shall apply.

Subpart C-Lost Earnings Not Attributable to Delayed or Erroneous Contributions

§ 1606.9 Loan allotments.

(a) Loan allotments deducted from a participant's pay but not timely received by the TSP recordkeeper due to employing agency error shall be subject to lost earnings. In such cases:

(1) The employing agency must submit a lost earnings record indicating the amount of the loan allotment, the pay date for which the loan allotment was actually submitted, and the pay date for which the loan allotment should have been submitted;

(2) The TSP recordkeeper shall compute lost earnings on the belated loan

allotment using the G Fund rates of return for each month of the calculation; (3) The amount of lost earnings calculated shall be deposited in the participant's account pro rata among the three investment funds on the basis of the balances of the three investment funds in the participant's account as of the end of the second month preceding the month during which the lost earnings record is processed.

(b) Loan allotments not deducted from a participant's pay due to employing agency error will not be subject to lost earnings.

§ 1606.10 Miscellaneous lost earnings.

Where lost earnings result from employing agency errors not specifically covered by this subpart or subpart B, the employing agency must consult with the Board or TSP Recordkeeper to determine the manner in which the employing agency shall submit lost earnings records or other data necessary to facilitate the payment of lost earnings.

Subpart D-Lost Earnings Records

§ 1606.11 Agency submission of lost earnings records.

(a) All lost earnings records required to be submitted pursuant to this part must be submitted to the TSP Recordkeeper in the manner and format prescribed in instructions provided to employing agencies by the Board or TSP recordkeeper.

(b) Where this part requires submission of lost earnings records, the employing agency must submit a separate lost earnings record for each pay period affected by the error. A lost earnings record may include all three sources of contributions, or it may include loan allotments, but may not include both loan allotments and contributions.

(c) Where this part requires the employing agency to indicate on a lost earnings record the investment fund to which a contribution would have been deposited had an employing agency error not occurred, that determination must be made solely on the basis of a properly completed allocation election on a Form TSP-1 that was accepted by the employing agency before the date the contribution should have been made, and that was still in effect as of

that date. Where no such allocation election was in effect as of the date the contribution would have been made had the error not occurred, the lost earnings record submitted by the employing agency must indicate that the contributions should have been made to the G Fund. Under no circumstances may a participant or employing agency choose, after the date a contribution should have been made or the date that it was made to an erroneous investment fund, the investment fund to which the contribution would have been made had the employing error not occurred.

(d) With respect to employing agency errors that cause money not to be invested in the Thrift Savings Fund, lost earnings records may not be submitted until the money to which the lost earnings relate has been invested in the Thrift Savings Fund. Where the employing agency error involved delayed TSP contributions, not lost earnings shall be payable unless and until the associated payment records are submitted in accordance with the provisions of 5 CFR part 1605. Lost earnings records and the delayed payment records to which they relate may be submitted simultaneously;

(e) Where an employing agency erroneously submits a lost earnings record that is processed by the TSP recordkeeper, the employing agency must subsequently submit a lost earnings record indicating that the previous lost earnings transaction should be reversed.

§1606.12 Agency responsibility.

(a) The employing agency whose error caused the delayed or erroneous investment of money in the Thrift Savings Fund shall, in a manner consistent with paragraph (b) of this section, be ultimately responsible for payment of any lost earnings resulting from that

error.

(b) The employing agency that submitted payment records or loan allotments that are subject to lost earnings shall be responsible for submitting lost earnings records relating to those submissions, and any lost earnings calculated shall be charged to that employing agency. Where another employing agency committed the error that

caused the delayed or erroneous submission by the first employing agency, the employing agency that was charged for the lost earnings may seek reimbursement from the other employing agency.

Subpart E-Processing Lost
Earnings Records

§ 1606.13 Calculation and crediting of lost earnings.

(a) Lost earnings records submitted or generated pursuant to this part shall be processed by the TSP recordkeeper during a mid-month processing cycle;

(b) Lost earnings records received, edited, and accepted by the TSP record keeper by the next-to-last business day of a month shall be processed in the next month's mid-month processing cycle. Lost earnings records that are received, edited, and accepted on the last business day of a month shall be processed in the second mid-month processing cycle following acceptance;

(c) In calculating lost earnings for a participant's account attributable to any lost earnings record, investment gains and losses calculated in different investment funds but within one source of contributions shall be offset against each other to obtain a net investment gain or loss for that source of contributions. Gains and losses for different sources of contributions shall not be offset against each other;

(d) Where the de minimis rule of paragraph (d)(1) of §1606.3 of this part is met with regard to delayed contributions or loan allotments, the calculation of lost earnings shall commence with the pay date for the pay period for which the contributions would have been made had the employing agency error not occurred. With regard to lost earnings not related to delayed contributions or loan allotments, lost earnings shall commence with the month during which the employing agency error caused the failure to invest in the Thrift Savings Fund money that would have been invested had the employing agency error not occurred, or with the month that the money was invested in an incorrect investment fund. Lost earnings calculations shall conclude as of the end of the month
