Cure Notices, Excusable Delay and Reprocurement Costs
A default termination begins with a letter that gives ten days to fix something, and it ends with a demand for the difference between the original price and what the replacement cost. Between the two sits the only question that matters: whether the delay was excusable.

The rule in short
Where a contractor fails to make progress or to comply with a provision, the contracting officer must give a cure notice allowing at least ten days to correct before terminating for default. Failure to deliver on time needs no cure notice. A delay arising from causes beyond the contractor's control and without its fault is excusable, provided written notice of the cause is given within ten days of the delay beginning. Default exposes the contractor to reprocurement costs.
Three grounds support a default termination on a fixed-price supply or service contract. Failure to deliver the supplies or perform the services within the time specified. Failure to make progress so as to endanger performance, where the contractor does not cure within ten days of notice. And failure to perform any other provision, again with a ten-day cure period. Only the first requires no warning.
The letter, and what it must contain
Where the ground is failure to make progress or failure to comply with a provision, the contracting officer must give written notice specifying the failure and allowing at least ten days to cure before terminating. The notice is a condition of the termination, not a courtesy, and a default taken without one on a ground that required one is defective.
A cure notice is available only if time permits. The notice must be issued far enough before the delivery date that the ten-day period, plus whatever time the government needs to evaluate the response, still leaves the schedule intact. Where the delivery date is imminent or has passed, the cure notice route is unavailable and the government uses a show cause notice instead.
Answering a cure notice is a technical exercise rather than a rhetorical one. Address each specified failure, state what has already been done, give a dated recovery plan with milestones, and identify any excusable cause with the supporting facts. A response that disputes the characterization without describing corrective action reads as a refusal to cure.
The defense that decides the outcome
The contractor is not liable for excess costs where the failure to perform arises out of causes beyond its control and without its fault or negligence. The clause lists examples: acts of God or of the public enemy, acts of the government in either its sovereign or its contractual capacity, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes and unusually severe weather.
The list is illustrative rather than exhaustive, and the two-part test governs. Beyond control means the contractor could not have prevented the event. Without fault or negligence means the contractor's own conduct did not contribute, which is where most arguments fail. A supplier chosen without diligence, a workforce plan with no margin, or a subcontract signed without a delivery commitment all supply the fault the test asks about.
An excusable delay entitles the contractor to a schedule extension and protects it against excess costs. It does not produce compensation for the cost of the delay. Money for delay comes from a different source: government-caused delay, suspension of the work, or a constructive acceleration, each of which runs through its own clause. A contractor whose whole case is that the delay was excusable will get more time and no payment.
| Instrument | When used | Period allowed | Effect | What it leads to |
|---|---|---|---|---|
| Cure notice | Failure to progress or to comply, with time remaining | At least ten days | A condition of terminating on that ground | Cure, or a default termination |
| Show cause notice | After a delivery date has passed | As stated in the notice | Builds the record before a decision | Default, forbearance, or a new schedule |
| Notice of excusable delay | Within ten days of the delay beginning | Ten days, or longer if allowed | Preserves the defense | A schedule extension |
| Default termination | Ground established and no cure | Effective on the notice | Contract ends; title to materials may transfer | A demand for excess reprocurement costs |
| Conversion to convenience | The default is found improper | Not applicable | Rights become those of a convenience termination | A settlement proposal |
What the government can recover afterward
Following a default, the government may acquire similar supplies or services and hold the contractor liable for any excess costs. The demand is a government claim, asserted by a contracting officer's decision, and it is contestable through the ordinary route in claims, certification and the disputes process.
Four conditions constrain the recovery and each is a defense worth testing. The reprocured items or services must be the same as or similar to those terminated. The government must have acted within a reasonable time after the termination. It must have used the method that would produce the lowest reasonable cost in the circumstances. And it must have mitigated, rather than paying a premium for speed that the record does not justify.
Excess costs are not the only exposure. Where a liquidated damages clause applies, damages accrue for the period of unexcused delay independently of the reprocurement. And the government may require the contractor to transfer title to and deliver completed work, partially completed work, materials and drawings, which removes the contractor's practical leverage.
Why the conversion remedy is the real objective
Where a default termination is found improper, the rights and obligations of the parties become the same as if the termination had been issued for the convenience of the government. That conversion is the central reason to contest a default. It replaces a demand for excess costs with an entitlement to be paid for work performed, through the process described in the settlement proposal after an early ending.
Improper defaults arise in recognizable ways: a cure notice never issued where one was required, a cure period too short for the failure alleged, a schedule already waived by acquiescence in continued performance, an excusable cause established on the record and ignored, or a termination taken while a directed change was still being priced under the changes clause.
The consequences also outlive the contract. A default termination is part of the performance record examined the next time a contracting officer asks whether the firm is responsible, which is the question described in responsiveness and responsibility. Costs incurred responding to a cure notice and preparing a settlement are tested under the principles in the three cost tests, so they should be segregated from the day the notice arrives.
Points to carry away
- A cure notice is required before terminating for failure to make progress or to comply with a provision.
- The cure period is at least ten days, and a cure notice is usable only if time remains in the schedule.
- Late delivery on the delivery date requires no cure notice at all.
- An excusable delay is one beyond the contractor's control and without its fault or negligence.
- The cause must be reported in writing within ten days of the delay beginning.
- An improper default termination is converted into a termination for convenience.
Questions readers ask
Is a subcontractor's failure an excusable cause?
Only on two conditions. The delay must arise from causes beyond the control and without the fault or negligence of both the prime and the subcontractor, and the supplies or services must not have been obtainable from other sources in sufficient time to meet the schedule. That second condition defeats most subcontractor arguments, because an alternative source usually existed at a higher price. A prime that chose not to pay the premium made a commercial decision rather than suffering an uncontrollable event.
What is a show cause notice and how is it different from a cure notice?
A cure notice is issued while time remains in the schedule and gives the contractor a defined period to correct a failure before termination becomes available. A show cause notice is issued after a delivery date has passed and asks the contractor to explain why it should not be terminated for default. It is not a prerequisite to termination and does not extend anything. It is an opportunity to place excusable causes on the record before the decision is made, and it should be answered in detail.
Can the government lose the right to terminate by letting work continue?
Yes. Where a delivery date passes and the government permits the contractor to continue performing without reserving its rights, it can be found to have waived the schedule. After a waiver the government must establish a new, reasonable delivery date before it can terminate for failure to meet a date. Agencies avoid this by sending a reservation of rights along with any forbearance, and contractors should note whether one was sent, because its absence is a defense.

The Debriefing and the Clock It Starts
An offeror excluded before award, or notified of an award in a negotiated procurement, may obtain a debriefing by written request made within three days of the notice. A required debriefing must disclose the evaluation of the offeror's own proposal, the awardee's evaluated price and technical rating, any overall ranking and the rationale for award. It may not disclose point-by-point comparisons. The debriefing date controls both the protest deadline and the window for the automatic suspension.
Sealed Bidding and Negotiated Procurement Compared
Sealed bidding is required where time permits, award will be made on price and price-related factors, discussions are unnecessary, and more than one bid is expected. Bids are opened publicly and award goes to the responsible bidder whose responsive bid is most advantageous considering price alone. Negotiated procurement evaluates proposals against stated factors, permits a competitive range and discussions, and allows an award to other than the lowest price where the solicitation says so.
The Settlement Proposal After a Contract Is Ended Early
On a convenience termination the contractor stops work, terminates subcontracts, protects and disposes of property, and submits a settlement proposal within one year of the effective date unless the period is extended in writing. Recoverable amounts include preparations and work done, initial costs, settlement expenses, subcontractor settlements, and reasonable profit on work performed. Anticipatory profit is not recoverable, and a loss contract carries no profit.
