    FAR 49.603-5Cost-reimbursement contracts-partial termination.

    Plain-English Summary

    FAR 49.603-5 provides a model settlement agreement clause for use in SF 30 when a cost-reimbursement contract is partially terminated. It addresses how the parties document the settlement of the termination settlement proposal, identify the notice of termination, and amend the contract to remove the terminated portion. The section also requires the terminated work to be described with enough specificity to avoid uncertainty, including line item numbers, descriptions, quantities, unit and total prices, and any other clarifying details. It further directs the parties to reduce the contract fee, and, when appropriate, the estimated cost, to reflect the partial termination. Finally, it preserves the contractor’s right to continue billing allowable costs and earned fee for the terminated portion on SF 1034 under the contract and FAR part 31. In practice, this section is a drafting tool that helps contracting officers and contractors memorialize a partial termination cleanly, prevent disputes over what work was removed, and ensure continued reimbursement is handled correctly after termination.

    Key Rules

    Use SF 30 settlement language

    The agreement is inserted in Block 14 of SF 30 for settlement agreements arising from a partial termination of a cost-reimbursement contract. The clause is intended to memorialize the settlement of the termination settlement proposal tied to the specific notice of termination date.

    Identify the terminated work precisely

    The terminated portion must be deleted from the contract and described clearly enough to avoid ambiguity. The model requires line item numbers, descriptions, quantities terminated, unit and total prices, and any other explanation needed to prevent uncertainty or misunderstanding.

    Adjust fee and cost amounts

    The contract fee must be decreased by the agreed amount, showing the original and revised fee. If appropriate, the estimated cost of the contract must also be decreased, with the original and revised estimated cost stated in the agreement.

    Preserve reimbursement for allowable termination costs

    The contractor’s allowable costs and earned fee, if any, for the terminated portion continue to be reimbursed on SF 1034. Those reimbursements remain subject to the contract terms and FAR part 31 cost principles.

    Settlement agreement finalizes the partial termination

    The document is a supplemental agreement that settles the termination settlement proposal, meaning it is the written record of the parties’ agreement on the financial and contractual consequences of the partial termination.

    Responsibilities

    Contracting Officer

    Prepare or use the SF 30 settlement language, ensure the notice of termination date is correctly identified, clearly amend the contract to delete the terminated portion, and document the agreed reductions in fee and, when appropriate, estimated cost.

    Contractor

    Submit and support the termination settlement proposal, agree to the contract modifications reflected in the settlement, and continue to bill allowable costs and earned fee for the terminated portion using SF 1034 in accordance with the contract and FAR part 31.

    Agency

    Ensure the settlement agreement is properly executed and retained in the contract file, and support administration of reimbursement and closeout actions associated with the partial termination.

    Practical Implications

    1

    The biggest drafting risk is ambiguity about what was terminated; vague descriptions can lead to disputes over remaining work, pricing, and billing.

    2

    Fee and estimated cost adjustments must be consistent with the settlement; failing to update them can create accounting and payment errors.

    3

    Even after partial termination, the contractor may still bill allowable termination-related costs and earned fee, so payment staff must distinguish those charges from ongoing performance costs.

    4

    The SF 30 language is a model, but it should be tailored to the actual contract line items and termination facts to avoid uncertainty.

    5

    Because reimbursement continues under FAR part 31, unsupported or unallowable costs can still be questioned or disallowed during settlement review.
