(2) If the error involves an employing agency's failure to deduct from basic pay contributions (in whole or in part) on behalf of an individual in accordance with section 8432(a), the regulations shall not provide for the payment of any lost earnings which would be attributable to—

(A) the contributions that the agency failed to deduct from basic pay in accordance with section 8432(a); or

(B) any related contributions under section 8432(c)(2) that the employing agency is not required (by statute or otherwise) to make up.

(1) shall include—

(A) procedures for computing lost earnings; and
