The Secretary of Defense (“government”) appeals the Armed Services Board of Contract Appeals’ (“Board’s”) decision holding invalid two settlement agreements (Modifications 25 and 29) between the government and the contractor and awarding a price adjustment pursuant to the “Government Delay of Work” clause in the contract.

BACKGROUND
This contract dispute has a long and complex history which is fully recounted in the Board’s decision. Freedom NY, 01-2 B.C.A.(CCH) at 156,045-061. We will summarize the portions relevant to this appeal.
The contractor’s predecessor, Freedom Industries, Inc. (“FII”), was put on a list of approved producers of Meal, Ready to Eat (“MRE”) combat rations in March of 1983 by the Defense Logistics Agency (“DLA”) and the Defense Personnel Support Center (“DPSC”) (collectively “government”). FII was awarded MRE contract No. DLA13H-85-C-0591, in the amount of $17.2 million, on November 15, 1984. This contract represented the contractor’s only business, a fact known to the government. The government agreed to *1323 make progress payments in the amount of 95% of incurred costs.
The contractor agreed to process, assemble, and package MREs that contained twelve separately packaged menu items, some of which were to be provided by the government, others by the contractor. The final lot of MREs was due, F.O.B. Bronx, New York, on December 31, 1985, with progress payments to be made periodically. All costs were treated as direct; and, since this was the contractor’s only contract, all costs were allocable to it.
The contract also incorporated several clauses from the Defense Acquisition Regulations (“DAR”), including two concerning the government’s right to withhold progress payments for defaults by the contractor: “Progress Payments for Small Business Concerns” (32 C.F.R. § 7-104.35(b) (1982)) and “Progress Payments” (32 C.F.R. 7-2003.64 (1974)). The first of these clauses provided, in pertinent part:
The Contracting Officer may reduce or suspend progress payments, or liquidate them at a rate higher than the percentage stated in (b) above [95%], or both, whenever he finds upon substantial evidence that the Contractor (i) has failed to comply with any material requirement of this contract, (ii) has failed to make progress, or is in such unsatisfactory financial condition, as to endanger performance of the contract, (iii) has allocated inventory to this contract substantially exceeding reasonable requirements, (iv) is delinquent in payment of the costs of performance of this contract in the ordinary course of business, (v) has so failed to make progress that the unliquidated progress payments exceed the fair value of the work accomplished on the undelivered portion of this contract, or (vi) is realizing less profit than the estimated profit used for establishing a liquidation percentage in paragraph (b), if that liquidation percentage is less than the percentage stated in paragraph (a)(1).
32 C.F.R. § 7-104.35(b), ¶ (c) (1982). The second clause provided, in pertinent part:: The appropriate “Progress Payment” clause ... included in the contract ... shall be inoperative during the time the contractor’s accounting systems and controls are determined by the Government to be inadequate for segregation and accumulation of contract costs.
32 C.F.R. § 7-2003.64 (1974).
The contract did not run smoothly. The contractor repeatedly missed deadlines for delivery of the MRE’s. The contractor claimed that the government was interfering with its ability to perform the contract by, among other things, failing to make timely progress payments. The government claimed that the contractor was in default, and thus repeatedly delayed progress payments, or failed to make them at all.
In one of many efforts to settle their respective claims, the contractor and the government negotiated Modification 25, which was signed by both parties on May 29, 1986. Among other things, it released the government from “all claims for all happenings and/or occurrences which have arisen to date under law and/or relating to the contract,”, except for a specific occurrence involving a subcontractor. Freedom NY, 01-2 B.C.A. (CCA) at 156,056. In return, the contractor received an extension of the delivery schedule and a price adjustment. The modification contained an integration clause as follows: “Both parties expressly state that the aforesaid recitals are the complete and total terms and conditions of their Agreement.” Id.
During the course of the negotiations concerning the modification, the government allegedly agreed to the provisions of a side agreement which was not included in the final document signed by both par *1324 ties. This alleged side agreement was memorialized in two letters sent by the contractor along with what would become Modification 25. These letters were substantively identical, and both were sent before the execution of Modification 25 on May 29, 1986. The first letter was sent May 13, 1986; the second, which corrected some minor mistakes, was sent May 28, 1986. The letters both stated that the “settlement is reflected in part in the Contract Modification” and requested that the side agreement “be confirmed as soon as practical.” (J.A. 298, 300, 301, 303) (emphasis added). This alleged side agreement consisted solely of promises supposedly made by the government, most importantly that, if the contractor were “otherwise qualified,” the government would “negotiate a fair and reasonable contract” with the contractor for additional MRE’s to be provided beginning in 1987. The government’s only response was a May 30, 1986, letter which denied that such a side agreement existed, and it is undisputed that the government did not perform the promises allegedly made therein.
Modification 25 did not resolve the disputes between the contractor and the government, nor did Modifications 26, 27, or 28. The parties began negotiations for Modification 29 in the fall of 1986. While these negotiations were occurring, the administrative contracting officer approved progress payment 21, in the amount of $700,000, on October 3, 1986. An internal government memorandum recited that “[c]onsidered in [the administrative contracting officer’s] decision was the best interest of the Gov’t., the contract loss ... progress payments and cases accepted to date ... disallowances and Modification [29].” Despite the administrative contracting officer’s approval, and even though the government knew that the contractor was in financial distress, the government withheld progress payment 21 and informed the contractor that it would not make the payment until the contractor agreed to Modification 29. The contractor did so on October 7, 1986. Modification 29 released the government from “all manner of action, causes of action, suits, proceedings ... damages, claims, and demands whatsoever, in law or equity or under administrative proceedings,” except for those related to Zyglo testing of the rations. Freedom NY, 01-2 B.C.A. (CCA) at 156,057. In return, the government extended the delivery schedule by one month. Id.
The contract was terminated for default by the government in 1987. In 1991, the contractor brought a claim for breach of contract, constructive change, and improper termination for default before the contracting officer. This was denied, and the contractor appealed to the Board. The scope of the contractor’s appeal — specifically, whether it was limited to determination of whether the government had properly terminated the contract for default, or whether it also included breach claims— was unclear. In May 1996 the Board held that the default termination had been improper. The default termination was therefore converted to a termination for convenience; the decision was, in this respect, favorable to the contractor.

However, the Board also went on to deny the contractor’s claims for breach of contract. In so doing, the Board made determinations that were adverse to the contractor, including that the alleged side agreement was not part of Modification 25 and that Modification 29 was not obtained by duress. The contractor moved to vacate the portion of the decision that denied its contract claims on the ground that it had been surprised to its prejudice because it had not expected that the appeal would include a determination of its con
*1325
tract claims. In August 1996 the Board agreed with the contractor.

Thereafter, the parties stipulated to some facts, and an eleven-day trial was held to resolve the others. During the trial, the Board heard conflicting testimony about the alleged side agreement to Modification 25. Henry Thomas, the contractor’s president, testified that the modification to which the contractor agreed was reflected only in part in the language of Modification 25; the rest of the agreement was reflected in the letters of May 13 and 28. He also testified that the contractor would not have agreed to Modification 25 without the alleged side agreement, and that the government knew this. When asked how he knew that the government had agreed to the alleged side agreement, Thomas testified that the government was in possession of it and “[n]o one objected. Nobody sent me anything. Nobody called me. Nobody said anything.” (Tr. at 650.) Colonel Frank Francois, a consultant hired by the contractor, testified that at the meeting when Modification 25 was signed (which he had attended), the procuring contracting officer told the contractor that he had approval to agree only to Modification 25. However, Francois testified that he (Francois) understood Modification 25 to include the alleged side agreement. The procuring contracting officer testified that, while he had received the letters, Modification 25, as written, contained the parties’ complete agreement. He testified, “There is no side agreement. There is no attachment to the modification.” Freedom

[Y]our letter [of May 28] indicated that other parts of our agreement are not reflected in the contract modification. This is not correct. The agreement reached as a result of our discussion is contained in whole and in its entirety in the contract modification.
(J.A. at 308.)
In November of 2000, the parties settled the amount due for termination subject to any adjustment made as a result of the appeal pending before the Board.
On August 28, 2001, the Board rendered its decision.
Freedom NY,

Also contrary to its earlier, vacated finding, the Board held that the release in Modification 29 could not be enforced because it had been obtained by duress. Id. at 156,067. The elements of duress, the Board held, were:
(1) [0]ne party involuntarily accepted the terms of another; (2) the circumstances permitted no other alternative; (3) such circumstances were the result of coercive acts of the other party.
Id. The coercive act, the Board held, was the government’s withholding of the progress payment. The contract “gave the contracting officer no right to withhold an approved progress payment until the contractor signed a contract modification,” the Board explained. Id. The Board found that the government’s conduct “was the predominant, if not sole, cause of’ the contractor’s performance problems, and hence its financial distress. Id. at 156,060. Since the government “was well aware of the contractor’s financial distress,” the Board concluded, its “delaying of payment ... coerced [the contractor] to sign [Modification 29].” Id. at 156,067.
The Board held, however, that the contractor could recover only under the standard “Government Delay of Work” clause, which provided equitable adjustment for government delay, including a delay “by an act of the Contracting Officer in the administration of this contract, which act is not expressly or impliedly authorized by this contract,” i.e., a breach. 33 C.F.R. § 7-104.77(f) (1984). The Board held that the contractor could not recover for breach of contract, because the government’s breaches all constituted government delay. “A contractor cannot maintain a breach claim for Government delay when relief is available under the contract,” the Board explained. Id. at 156,067.
The contractor moved for reconsideration on October 11, 2001, arguing, among other things, that the government delays constituted a constructive change of the method of performance of the contract; that the government’s conduct resulted in a cardinal change; and that the contractor was entitled to damages for contracts later awarded to other contractors. On December 7, 2001, the Board denied the motion.

The government timely appealed. The contractor cross appealed. We have jurisdiction pursuant to 28 U.S.C. § 1295(b).
*1327 DISCUSSION
We review the Board’s decision under the following standard:
[T]he decision of the agency board on any question of law shall not be final or conclusive, but the decision on any question of fact shall be final and conclusive and shall not be set aside unless the decision is fraudulent, or arbitrary, or capricious, or so grossly erroneous as to necessarily imply bad faith, or if such decision is not supported by substantial evidence.
41 U.S.C. § 609(b) (2000). The substantial evidence standard requires only “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.”
AT&T Communications, Inc. v. Perry,
I
The government’s primary contention on appeal is that the Board erred in its conclusion that Modifications 25 and 29 did not release the government from liability.
In the course of performance of a government contract, disputes arise between the contractor and the government with some frequency. Federal policy favors settlement of disputes before they develop into litigation. “The Government’s policy is to try to resolve all contractual issues in controversy by mutual agreement at the contracting officer’s level. Reasonable efforts should be made to resolve controversies prior to the submission of a claim.” 48 C.F.R. § 33.204 (2002). The prompt settlement of those disputes serves the interests of the contractor, the government, and the public at large. In post-contract litigation, the Board and the courts should be reluctant to invalidate such settlements absent a clear showing of invalidity. “ ‘[T]hose who employ the judicial appellate process to attack a settlement through which controversy has been sent to rest bear a properly heavy burden’ of proof that the agreement was improperly obtained.”
Tiburzi v. Dep’t of Justice,
Here we conclude that the Board erred in invalidating Modification 25 on the ground that the government had breached an alleged side agreement, but that the Board correctly concluded that Modification 29 was invalid due to duress.
A. Modification 25
The parol evidence rale provides that when a document is integrated, “barring certain limited exceptions (e.g., fraud), a party to a written contract cannot supplement or interpret that agreement with oral or parol statements that conflict with, supplant, or controvert the language of the written agreement itself.”
Schism v. United States,
To be sure, if two separate agreements are negotiated at the same time, both of which meet applicable contract requirements, including consideration, both may be enforceable.
See, e.g.
John D. Calamari & Joseph M. Perillo,
The Law of Contracts
§ 3.2(a) (4th ed. 1998);
Brennan v. Carvel
*1328
Corp.,
When a document is completely integrated, no additional terms may be added, whether consistent or inconsistent, through parol evidence.
McAbee Constr., Inc. v. United States,
We have recognized the importance of integration clauses in determining whether a contract is completely integrated. In
McAbee,
we emphasized that, although they are not dispositive, integration clauses create a “strong presumption that a contract [is], as it purports] to be, a fully-integrated agreement.”
Where, as here, the parties are both commercial entities or the government, integration clauses are given particularly great weight. As the Second Circuit has stated, “the presumption of completeness is particularly strong where sophisticated parties have conducted extensive negotiations prior to entering into the agreement.”
Telecom Inti Am., Ltd. v. AT & T Corp.,
Here we conclude that, in light of the integration clause in the contract, the Board erred in invalidating Modification 25 on the ground that the government breached an alleged side agreement. Although our cases recognize that extrinsic evidence may be considered on the issue of integration,
2
we think that such circumstances are extremely limited where there is an integration clause.
See McAbee,
There are no such circumstances present here. Indeed, in this case, as in
McA-bee,
the circumstances surrounding the negotiation of Modification 25 support a finding of complete integration. Here, as in
McAbee,
We conclude that Modification 25 was an integrated document to which no additional terms could be added through parol evidence, and that it did not contain the unilateral promises allegedly made by the government. Accordingly, we reverse the Board’s decision invalidating Modification 25 on the ground that the government breached the alleged side agreement, and remand for consideration of the contractor’s other alleged grounds for invalidation of Modification 25.
B. Modification 29
We reach a different result concerning the validity of Modification 29. We affirm the finding of duress.
To render a contract unenforceable for duress, the party “must establish that (1) it involuntarily accepted [the other party’s] terms, (2) circumstances permitted no other alternative, and (3) such circumstances were the result of [the other party’s] coercive acts.”
Dureiko v. United States,
In addressing the first two parts of this test, we have held that government coercion must have been the cause of the contractor’s agreement. 4 Here, however, the government does not dispute that its withholding of progress payments caused the contractor to agree to Modification 29. The sole question, then, is whether the government’s action was coercive.
Our past decisions make clear in the procurement context proof of coercion requires proof of wrongful action by the government. For example, in
Johnson, Drake & Piper, Inc. v. United States,
our predecessor court emphasized that “[e]conomic pressure and even the threat of considerable financial loss are not duress.”
ha[s] done away with the requirement of an illegal act ... An act the government is empowered to take under law, regulation, or contract may nonetheless support a claim of duress if the act violates notions of fair dealing by virtue of its coercive effect.
Here the contractor has shown the existence of a wrongful act. It is admitted that the contractor was in deep financial distress at the time Modification 29 was signed. The administrative contracting officer approved the progress payment based on the factors that the con *1331 tract required be considered: “the best interest of the Gov’t., the contract loss ... progress payments and cases accepted to date ... disallowances and Modification [29].” Nevertheless, the government withheld the progress payment, for the sole purpose of pressuring the contractor into signing Modification 29. The contract provided for the withholding of progress payments if the contractor
(i) has failed to comply with any material requirement of this contract, (ii) has failed to make progress, or is in such unsatisfactory financial condition, as to endanger performance of the contract, (iii) has allocated inventory to this contract substantially exceeding reasonable requirements, (iv) is delinquent in payment of the costs of performance of this contract in the ordinary course of business, (v) has so failed to make progress that the unliquidated progress payments exceed the fair value of the work accomplished on the undelivered portion of this contract, or (vi) is realizing less profit than the estimated profit used for establishing a liquidation percentage in paragraph (b), if that liquidation percentage is less than the percentage stated in paragraph (a)(1).
The contract also allowed the government to withhold progress payments “during the time the contractor’s accounting systems and controls are determined by the Government to be inadequate for segregation and accumulation of contract costs.” The contract did not allow the government to withhold progress payments simply to pressure the contractor into giving up its rights under the contract. The government could not have had a good-faith belief that withholding for this purpose was permissible under the contract.
The government argues that the withholding of the progress payments was permissible because the contractor was in default or because the government in good faith believed that the contractor was in default. It is true that a good-faith withholding of the progress payment because the government believed the contractor’s performance was deficient would not constitute duress. “[T]he assertion of a legitimate contract right cannot be considered as violative of a duty of good faith and fair dealing,” and thus cannot be coercive.
Nassaf II,
But the wrongfulness of the government’s action must be judged at the time it was taken.
Pigeon v. United States,
*1332 III .
The government’s final basis for appeal, that the Board’s decision was arbitrary and capricious because it conflicted with an earlier decision of the Board, is frivolous. The portion of the earlier decision relied on by the government was vacated by the Board because the contractor had not expected the issue of breach to be decided at that stage of the proceedings.
Freedom NY,
96-
We delete reference to docket number ASBCA No. 43965 from the caption of our 7 May 1996 opinion and in the “DECISION” section thereof; we vacate that portion of the decision denying ASBCA No. 43965; and we restore the appeal in ASBCA No. 43965 to our active docket.
Id.
Given this intent, the Board’s incomplete removal of the facts on which the vacated decision was based is irrelevant. The law of the case thus does not apply because “a vacated judgment ‘has no pre-clusive force either as a matter of collateral or direct estoppel or as a matter of the law of the case.’”
U.S. Philips Corp. v. Sears Roebuck & Co.,
IV
In its cross appeal, the contractor argues that the breaches by the government were so extensive as to constitute a cardinal change. A cardinal change, “occurs when the government effects an alteration in the work so drastic that it effectively requires the contractor to perform duties materially different from those originally bargained for.”
Krygoski Constr. Co. v. United States,
We conclude that the Board’s finding was supported by substantial evidence. The Board found that the government: (1) improperly denied, suspended,

and delayed making progress payments,

The contractor also argues that the Board should have awarded anticipated profits and fixed overhead associated with future contracts which, it contends, it would have been awarded as an approved MRE-producer absent the government’s breach of contract. It relies principally on
Locke v. United States,
We have considered the other points argued by the contractor and the government and find them to be without merit. 6

For the foregoing reasons, we affirm in part, reverse in part, and remand for fur *1334 ther proceedings consistent with this opinion.

McAbee,
. The Fourth Edition of the Williston treatise continues to recognize that "[p]erhaps most courts ... give presumptive effect to a merger clause,” but also recognizes the existence of a "minority view” that “parol evidence can ... be examined to determine whether the contract is integrated, and to explain what the words used in the contract mean.” Williston,
supra,
§ 33:16. Of course, any ambiguities in an integration clause can be resolved by considering the surrounding circumstances.
United States
v.
Winstar Corp.,
The Restatement also recognizes that the existence of an integration clause is "likely to conclude the issue whether the agreement is completely integrated.” Restatement (Second) of Contracts, § 216 cmt. e (1981); see also Calamari & Perillo, supra, § 3.6 (The rule "followed by most courts, is that a merger clause will ordinarily resolve the issue of total integration.”); James J. White & Robert S. Summers, Uniform Commercial Code § 2-12 (4th Ed. 2000) (A merger clause "should be effective to preclude a judge from admitting extrinsic evidence on a theory that the writing is not a complete and exclusive statement of the contract terms.”).
. In
Systems Technology,
we declined to find that delay in making an audit available by the government for five to six weeks amounted to coercion when there was no proof that the delay caused the contractor's financial distress.
. We have held that there was no enforceable side agreement in connection with Modification 25 promising future contracts.
. In light of our disposition of Modification 25, we do not address the contractor’s claim for interest dating from its certified claim of April 24, 1986. We note that it appears in any event that this claim was not properly raised below, and is thus foreclosed.
