    FAR 32.503-11Adjustments for price reduction.

    Plain-English Summary

    FAR 32.503-11 explains how to adjust progress payment accounts when the contract price goes down after payments have already been made. It covers two related situations: a retroactive downward price reduction under a redeterminable contract that includes progress payments, and an interim or voluntary price reduction under a redeterminable or incentive contract. In practice, the rule tells the contracting officer how to reconcile the government’s payment records so the contractor repays any overpayment on delivered items and the unliquidated progress payments balance is corrected for any overdeductions previously taken from billings. The section exists to keep progress payment accounting accurate when contract prices change after performance has begun, and to prevent either party from being unfairly advantaged or disadvantaged by the later price reduction. For contractors, this means a price decrease can trigger both a repayment obligation and a bookkeeping adjustment to the remaining progress payment balance. For contracting officers, it requires prompt recalculation and proper accounting treatment so the contract reflects the reduced price consistently across paid, billed, and unliquidated amounts.

    Key Rules

    Refund overpaid amounts

    When a retroactive downward price reduction occurs on a redeterminable contract with progress payments, the contracting officer must determine the refund due and recover the amount by which payments for delivered items exceed the amounts now due at the reduced prices. This is a direct repayment obligation tied to the revised contract price.

    Restore overdeductions

    The contracting officer must increase the unliquidated progress payments amount for any overdeductions previously taken from the contractor’s billings for delivered items. This prevents the government from keeping a progress payment reduction that is no longer appropriate after the price is lowered.

    Apply to redeterminable contracts

    Paragraph (a) applies specifically to retroactive downward price reductions under redeterminable contracts that provide for progress payments. The rule is aimed at contracts where the final price can be adjusted after performance has started.

    Apply to interim or voluntary reductions

    Paragraph (b) requires the contracting officer to increase the unliquidated progress payments amount when the contractor makes an interim or voluntary price reduction under a redeterminable or incentive contract. The adjustment is required even if the reduction is not imposed retroactively by the government.

    Keep progress payment records current

    The section requires the government to update the unliquidated progress payments balance whenever price reductions affect amounts previously billed or paid. Accurate accounting is essential so future progress payments are based on the correct remaining balance.

    Responsibilities

    Contracting Officer

    Determine the refund due after a retroactive downward price reduction, obtain repayment from the contractor for any excess paid on delivered items, and increase the unliquidated progress payments amount for overdeductions from billings. The contracting officer must also make the same unliquidated progress payments adjustment when the contractor makes an interim or voluntary price reduction.

    Contractor

    Repay any excess amounts identified by the contracting officer when delivered items were paid at prices higher than the reduced contract price. The contractor must also recognize that interim or voluntary price reductions can change the progress payment accounting balance and may affect future billings and payments.

    Agency Payment/Finance Personnel

    Support the accounting adjustment by updating progress payment records, reflecting the revised unliquidated balance, and ensuring repayment and offset actions are properly recorded in the payment system.

    Practical Implications

    1

    A price reduction does not just lower future prices; it can require a retroactive reconciliation of amounts already paid and billed. Contractors should expect a repayment demand if delivered items were overpaid under the old price.

    2

    The phrase "increase the unliquidated progress payments amount" is important because it can restore progress payment capacity after prior overdeductions. If this is missed, the contractor may be shorted on future progress payments.

    3

    Contracting officers need to distinguish between delivered items, billings, and unliquidated progress payments. Errors often happen when the government adjusts one part of the account but forgets to correct the others.

    4

    Interim or voluntary price reductions can trigger the same accounting adjustment even though the reduction was not imposed as a retroactive downward change. Contractors should not assume voluntary reductions are administratively neutral.

    5

    This section is mainly an accounting and recovery rule, but it has cash-flow consequences. A contractor may face both an immediate repayment obligation and a revised progress payment balance that affects future financing under the contract.

    Official Regulatory Text

    (a) If a retroactive downward price reduction occurs under a redeterminable contract that provides for progress payments, the contracting officer shall- (1) Determine the refund due and obtain repayment from the contractor for the excess of payments made for delivered items over amounts due as recomputed at the reduced prices; and (2) Increase the unliquidated progress payments amount for overdeductions made from the contractor’s billings for items delivered. (b) The contracting officer shall also increase the unliquidated progress payments amount if the contractor makes an interim or voluntary price reduction under a redeterminable or incentive contract.
