OPINION
The United States appeals the judgment of the United States Claims Court,
Background
On March 16, 1982, the Department of the Army (government) awarded Westech Corporation a contract to build a pressure recovery system for the high energy laser test facility at White Sands Missile Range, New Mexico. As required by the contract and pursuant to the Miller Act, 40 U.S.C. §§ 270a-270d (1982), Fireman’s Fund Insurance Company (Fireman’s Fund) agreed to be Westech’s surety by issuing both payment and performance bonds. The performance bond, relevant here, named Wes-tech as principal and the United States as obligee.
The construction contract provided that the government would make periodic progress payments to Westech but retain ten percent of each, unless the contractor made satisfactory progress during a payment period. In that event, the contracting officer could authorize payment in full. Westech performed satisfactorily through the first fourteen pay periods, but the government nevertheless retained ten percent of Westech’s monthly payments.' Thereafter, in May of 1983, because overtime expenditures necessary to meet the contract’s completion date were causing cash flow problems, Westech requested that the government pay it semi-monthly and release the funds previously retained under the contract. The government agreed. When the request was made, the project was about eighty-five percent complete, there was no indication that Westech would be unable to complete the contract, and the government believed releasing the retainage would redress complaints it had received from Westech subcontractors about late or nonpayments.
Throughout June and July of 1983, the government released $563,822, the full amount of the retainage. Notwithstanding continued complaints of nonpayment by Westech subcontractors and suppliers, the government also paid Westeeh’s subsequent semi-monthly progress payments in full. Unfortunately, neither of these accommodations was sufficient: by mid-December of 1983, the project had faltered and Westech employees and subcontractors had left the site.
In response to two routine progress inquiries — in March of 1983, before releasing the retainage, and in October of 1983, after doing so — the government had shared with Fireman's Fund its knowledge of payment problems between Westech and its subcontractors. But Fireman’s Fund did not notify the government until December 22, six days after Westech had abandoned the contract, that it was aware of Westech’s unpaid debts and that the government should not make any further payments to Westech without its written consent. Neither in the December 22 letter nor in either of the two earlier general status inquiries did Fireman’s Fund mention retainage; nor did it, in the October and December communications, question the government’s previous release of the retained funds.
Nevertheless, the government honored Fireman’s Fund’s request and withheld Westech’s first December progress payment. When no further progress had been made on the project and Fireman’s Fund and Westech had been given notice, the government terminated the contract for default on December 29 and asked Fireman’s Fund to resume work no later than January 10, 1984. Fireman’s Fund declined to assume the contract on such short notice, thereby defaulting under its performance bond. It did, however, fulfill its obligations under the payment bond by satisfy *497 ing over $2 million in subcontractor and supplier claims against Westech.
The government subsequently repro-cured the remainder of the contract. The reprocurement contractor substantially completed the project in April of 1984 and in a final decision dated September 24, 1985, the contracting officer assessed $583,903 in excess reprocurement costs against Fireman’s Fund. Fireman’s Fund challenged the assessment in the Claims Court, alleging that the government’s premature release of the retainage breached the bonded contract and prejudiced its interests. Accordingly, it argued that the court should release it from liability on its performance bond to the extent of the prejudice.
The Claims Court held that the government had materially departed from the contract by releasing the retainage to Wes-tech, thereby prejudicing Fireman’s Fund and substantially discharging it from liability on the performance bond. The court invoked the so-called
pro tanto
discharge rule: “if the obligee departed from or altered the contractual provisions relating to payments and/or the security of retained funds, a surety is discharged to the extent it can show injury, loss, or prejudice.”
Discussion
I.
The Claims Court recognized that it is unprecedented in this court to apply the
pro tanto
discharge rule to government contracts. It relied instead on cases from the Sixth, Seventh, and Eighth Circuits applying the rule to private contracts,
see Ramada Dev. Co. v. United States Fidelity & Guar. Co.,
As recited by the Claims Court and emphasized by Fireman’s Fund, “[i]t is well-settled in many jurisdictions that
if the obligee departed from or altered the contractual provisions relating to payments and/or the security of retained funds,
a surety is discharged from its obligations only to the extent it can show injury, loss, or prejudice.”
Paragraph 7(c) of the superseding general provision of the construction contract provides:
In making such progress payments, there shall be retained 10 percent (10%) of the estimated amount until final completion and acceptance of the contract work. However, if the Contracting Officer finds that satisfactory progress was achieved during any period for which a progress payment is to be made, he may authorize such payment to be made in full without retention of a percentage. Also, whenever the work is substantially complete, the Contracting Officer shall retain an amount he considers adequate *498 for the protection of the Government and, at his discretion, may release to the Contractor all or a portion of any excess amount....
Contrary to the trial court’s assertion that “the contract expressly stated that defendant had no discretion to release the retain-age accumulated during the first fourteen payments until the contract work was substantially complete,”
It is true that retainage is an incentive to complete the contract, but it is equally true that contractors may need full progress payments to finance the work. In this case, the government believed the contract might not be completed unless it released the retainage to alleviate Westech’s cash flow problems. It may be that, ideally, the government should hold retainage until the work is substantially complete instead of releasing it when “perhaps fleeting, temporary satisfactory progress during one or a few pay periods is achieved.” Id. at 230. But the government has considerable leeway in administering its contracts.
During performance, the Government’s role is substantially different from that of a mere stakeholder of a final contract payment. The [Government] has an important interest in the timely and efficient completion of the contract work. In furtherance of this interest, the Government contracts for a broad range of rights which are designed to promote continuation of the contract work. These provisions give the Government considerable discretion and flexibility in administering the contract. Public policy supports this flexibility in light of the various unforeseen circumstances which may hinder performance.
Argonaut Ins. Co. v. United States,
Apart from the
pro tanto
discharge rule — which, again, we find no occasion to peruse today — the government as obligee owes no equitable duty to a surety like Fireman’s Fund unless the surety notifies the government that the principal has defaulted under the bond. It is irrelevant whether the surety claims a right to funds during performance of the contract, or after it is completed when the government functions as a “stakeholder” of funds owed but not yet paid. In either event, notice by the surety is essential before any governmental duty exists.
See Balboa,
Fireman’s Fund did not notify the government of Westech’s failure to pay its subcontractors and suppliers or ask that payments to Westech be withheld until December 22, 1983, almost five months after the government had fully released the retainage which Fireman’s Fund now claims. That some subcontractors and suppliers had informed the government of Westech’s payment deficiencies prior to the release of the retainage does not substitute for notice by the surety and does not trigger the government’s equitable duty to act with reasoned discretion toward it. Fireman’s Fund simply cannot rely on Westech’s subcontractors or the government to protect its interests. By definition and agreement the surety protects the government’s interest, not the other way around.
We see no reason to impose on the government a duty toward the surety whenever a subcontractor or supplier complains of late or nonpayment by the contractor. Only the contract should limit the government’s flexibility in resolving payment disputes so minor, and perhaps so inevitable, that the surety itself doesn’t consider the contractor’s role in them a potential default under the bond. Only when the surety may be called upon to perform, that is, only when it may become a party to the bonded contract, should the government owe it any duty. The surety knows best when this may occur; consequently, only notice by the surety triggers the government’s equitable duty.
II.
Fireman’s Fund argues alternatively that the government owed it a
contractual
duty not to release the retainage until after the contract was substantially completed. Because the judgment of the trial court rested on Fireman’s Fund’s putative equitable rights — “[although a surety relies on a contract’s provisions in guaranteeing the contractor’s obligations, the surety must show harm to be discharged from liability because its rights are equitable, and not contractual, in nature,”
“Although it is conceivable that under certain circumstances a surety could assert rights against the Government under the third-party beneficiary rule, or even as one in privity of contract with the Government,”
Balboa,
To the extent Fireman’s Fund argues an implied-in-fact contract with the government exists, it also fails. The requirement for payment and performance bonds on contracts like Westech’s does not, on these facts, imply a contract between the government and the bondsman.
See Ransom v. United States,
Conclusion
Accordingly, the judgment of the Claims Court is reversed.
REVERSED.
Notes
In contrast to a performance bond, which is intended to protect the government, a payment bond is intended to protect persons supplying labor and materials to the contractor.
See
40 U.S.C. § 270a(a). Thus, the government is the intended third party beneficiary of the performance bond and the subcontractors and suppliers of a contractor are the intended third party beneficiaries of the payment bond. Fireman’s Fund has become subrogated to Westech’s con
