The total amount determined under subsection (a) to be due any employee engaged in the performance of a contract may be withheld from accrued payments due on the contract or on any other contract between the same contractor and the Federal Government. The amount withheld shall be held in a deposit fund. On order of the Secretary, the compensation found by the Secretary or the head of a Federal agency to be due an underpaid employee pursuant to this chapter shall be paid from the deposit fund directly to the underpaid employee.

If the accrued payments withheld under the terms of the contract are insufficient to reimburse a service employee with respect to whom there has been a failure to pay the compensation required pursuant to this chapter, the Federal Government may bring action against the contractor, subcontractor, or any sureties in any court of competent jurisdiction to recover the remaining amount of underpayment. Any amount recovered shall be held in the deposit fund and shall be paid, on order of the Secretary, directly to the underpaid employee. Any amount not paid to an employee because of inability to do so within 3 years shall be covered into the Treasury as miscellaneous receipts.
