((a)) Under regulations prescribed under , the head of an agency acquiring property or service from a business concern, who does not pay the concern for each complete delivered item of property or service by the required payment date, shall pay an interest penalty to the concern on the amount of the payment due. The interest shall be computed at the rate of interest established by the Secretary of the Treasury, and published in the Federal Register, for interest payments under section 7109(a)(1) and (b) of title 41, which is in effect at the time the agency accrues the obligation to pay a late payment interest penalty.

((b)) The interest penalty shall be paid for the period beginning on the day after the required payment date and ending on the date on which payment is made.

((c))

((1)) A business concern shall be entitled to an interest penalty of $1.00 or more which is owed such business concern under this section, and such penalty shall be paid without regard to whether the business concern has requested payment of such penalty.

((2)) Each payment subject to this chapter for which a late payment interest penalty is required to be paid shall be accompanied by a notice stating the amount of the interest penalty included in such payment and the rate by which, and period for which, such penalty was computed.

((3)) If a business concern—

((A)) is owed an interest penalty by an agency;

((B)) is not paid the interest penalty in a payment made to the business concern by the agency on or after the date on which the interest penalty becomes due;

((C)) is not paid the interest penalty by the agency within 10 days after the date on which such payment is made; and

((D)) makes a written demand, not later than 40 days after the date on which such payment is made, that the agency pay such a penalty,

((d)) The temporary unavailability of funds to make a timely payment due for property or services does not relieve the head of an agency from the obligation to pay interest penalties under this section.

((e)) An amount of an interest penalty unpaid after any 30-day period shall be added to the principal amount of the debt, and a penalty accrues thereafter on the added amount.

((f)) This section does not authorize the appropriation of additional amounts to pay an interest penalty. The head of an agency shall pay a penalty under this section out of amounts made available to carry out the program for which the penalty is incurred.

The recipient may not pay the penalty from amounts received from an agency. Amounts expended for the penalty may not be counted toward a matching requirement applicable to the grant. An obligation to pay the penalty is not an obligation of the United States Government.
