McCONNELL, Circuit Judge.

This appeal is the latest episode in a lengthy antitrust suit brought by Plaintiffs Flying J, Inc., TCH, L.L.C., CFJ Properties, TON Services, Inc., and CFJ (collectively "Flying J") against Defendant Comdata Network, Inc. ("Comdata"). The underlying lawsuit, filed in 1996, arose out of Comdata's alleged monopolization of two product markets related to the U.S. truck stop industry. In May 2001, after nearly five years of discovery and pretrial motions, the parties entered into a settlement agreement. Comdata agreed to pay $49 million in damages and grant Flying J two licenses intended to open the markets at issue. Conflict soon resumed, however, when the parties could not agree about the meaning of one of the two licenses. Aggrieved by what it interpreted as Comdata's refusal to honor one of the licenses, Flying J filed a motion to enforce the settlement agreement in May 2002. The district court determined that Comdata had breached the settlement agreement and ordered Comdata to implement the license as interpreted by Flying J. Exercising jurisdiction under 28 U.S.C. § 1292(a), we REVERSE. In so doing, we emphasize that it is not our task to determine what would best remedy the underlying antitrust violation, but solely to interpret the agreement reached between the parties, in light of its plain language and the intent of the parties.

I.

Plaintiff Flying J, Inc. owns and operates a nationwide chain of approximately 160 truck stops. Flying J estimates that there are approximately 4000 truck stops in the United States, roughly 1000 of which offer services comparable to its own truck stops. This appeal involves two markets closely related to the trucking industry: point-of-sale systems and trucker fuel cards.

Comdata provides transaction-processing services to the trucking industry. Among other things, it sells the Trendar System, a PC-based point-of-sale system that allows merchants to process customers' card transactions. When the customer's payment card is swiped through the Trendar card reader, Trendar software sends the transaction data to a third-party financial institution for authorization and settlement. Flying J presented evidence in the underlying litigation that Comdata had secured approximately 90% of the point-of-sale systems market by 2001. Virtually every major U.S. truck stop other than Flying J used the Trendar System.

Comdata also issues fuel cards to trucking companies, including a proprietary payment card ("the Comdata Card") and a Comdata MasterCard, referred to as the Comdata Fleet Card. According to Flying J, Comdata cards have dominated the trucker fuel card market for many years, securing a 70% share by 2001.

Proprietary payment cards offer two features relevant to this litigation. The first, called data capture, requires the truck driver to enter certain data at the time of the fuel purchase, typically including driver identification and odometer readings. The data is relayed in real time to the trucking company, allowing it to monitor the driver's location and activities. The second feature, called purchase control, allows trucking companies to restrict the type and quantity of items that the driver can purchase with the fuel card. A trucking company might, for example, allow its drivers to purchase motor oil and a certain amount of diesel fuel each day but prevent them from purchasing alcoholic beverages, a truck stereo, or enormous bags of pork rinds. Each trucking company can tailor purchase controls to suit its preferences. According to Flying J, data capture and purchase controls are essential to effective management of a long-haul trucking fleet, and they provide the principal incentive for trucking companies to give trucker fuel cards to their drivers rather than ordinary credit cards. Ordinary MasterCards do not have these features.

Comdata and Flying J (through its subsidiaries, TAB and TCH) issue proprietary cards with no logo other than their own, as well as MasterCards. The Flying J propriety card is called the TCH Fuel Card; its MasterCard is called the TCH Mastercard. Comdata MasterCards are called the Comdata MasterCard or Comdata Fleet Card, which mean the same thing. The Comdata and TCH MasterCards can be used either as ordinary MasterCards or as proprietary cards, depending on the arrangements reached with the particular merchant. These are called "dual function" cards.

As a condition of participating in the MasterCard network, MasterCard requires merchants to accept all MasterCards, regardless of the issuer. It is up to the particular merchant to decide whether to accept proprietary cards. In the discretion of the merchant, MasterCard regulations permit use of a "dual function" MasterCard as a proprietary card for a "proprietary account," defined as "an account . . . that is separate from a MasterCard account and is maintained by a company or organization other than the MasterCard member." MasterCard Bylaws and Rules, October 2002, Rule 6.6, JA 546. The proprietary account rules require a preexisting account, established according to a separate agreement, with each merchant.

Comdata MasterCards and TCH MasterCards therefore must be accepted by all merchants in the MasterCard network. But only if the merchants have an agreement with the issuer do the merchants treat these cards as proprietary cards (meaning that they effectuate the data capture and purchase control features of these cards). If the particular merchant is part of the MasterCard network but has not made any agreement with Comdata or THC, Trendar must process the transaction through the MasterCard network as an ordinary MasterCard transaction, without the data capture or purchase control features. If the merchant has agreed to accept the issuer's proprietary card, the merchant processes the issuer's MasterCard transaction as a proprietary card transaction, meaning that the transaction will be authorized and settled over a private network as opposed to the MasterCard network.

In an ordinary MasterCard transaction, Trendar sends transaction data to the merchant's chosen third-party financial institution, known as the acquirer. The acquirer, through its own system, sends the transaction data through the MasterCard network for authorization by the card issuer's bank and settlement through the MasterCard network. When a dual function card, such as the TCH MasterCard or the Comdata Fleet Card, is processed as an ordinary MasterCard, it does not provide trucking companies with real-time data capture or purchase control because the MasterCard network does not relay data quickly enough.

When Flying J entered the trucker fuel card market in the mid-1990s, it faced two significant barriers to entry. First, the Trendar System did not accept the TCH Fuel Card. Merchants using Trendar could not process TCH Fuel Card transactions; therefore, Flying J customers could not use the TCH Fuel Card at Trendar locations. Given the ubiquity of the Trendar System, this was a big problem for Flying J. Second, the record shows that Comdata engaged in a campaign to pressure truck stops not to accept the TCH Fuel Card. Prior to the 2001 settlement, Comdata placed over four hundred telephone calls to truck stops and threatened to raise transaction fees on Comdata cards if they agreed to accept the TCH Fuel Card.

In 1996, Flying J filed suit, charging Comdata with violation of the Sherman Act, 15 U.S.C. §§ 1- 7, through monopolization of the trucker fuel card market and the point-of-sale systems market. The parties settled in 2001. Comdata agreed to pay $49 million in damages and grant Flying J two licenses: the Comdata License and the Trendar License. In accordance with the parties' request, the district court reserved jurisdiction to enforce the terms of the settlement agreement. See Kokkonen v. Guardian Life Ins. Co., 511 U.S. 375, 114 S.Ct. 1673, 128 L.Ed.2d 391 (1994). This appeal concerns only the Trendar License as it pertains to processing the TCH MasterCard at unaffiliated merchants; that is, merchants who have not agreed to accept the proprietary TCH Fuel Card.

The Trendar License grants to TCH a "nonexclusive license . . . to access and use the Trendar System solely for the Permitted Uses." Trendar License Art. 4.1 Permitted uses include "access and use of the Trendar System by TCH and its cardholder customers." Id. Art. 1. In short, the Trendar License provides TCH access to the Trendar System, and it enables TCH to effect data capture and purchase controls in transactions involving the TCH MasterCard. Pursuant to the Trendar License, Comdata and Flying J configured the Trendar System to accept the TCH Fuel Card. They also configured Trendar to process TCH MasterCards as proprietary transactions if the merchant had agreed to accept the TCH Fuel Card.

This cooperative endeavor soon reached an impasse when Comdata refused to configure Trendar to process TCH MasterCards as proprietary transactions at retail outlets where the merchants had not agreed to accept the TCH Fuel Card. The dispute centers on Article 4.2 of the Trendar License, which provides:

All TCH Card Transactions processed through the Trendar System, including without limitation TCH Cards bearing a MasterCard or Visa brand, shall be cleared directly through TCH as opposed to any third party network, such as and without limitation the MasterCard network or Visa network, to the fullest extent permitted by the policies, rules, or regulations, as amended from time to time (including their interpretations thereof) by third party network providers.

Trendar License Art. 4.2. Many Flying J competitors, such as Pilot, Petro, and Travel Centers of America, do not accept the TCH Fuel Card. Because truck stops operated by these competitors accept MasterCard, they must accept the TCH MasterCard, but they do so as an ordinary MasterCard transaction, not as a proprietary transaction. Thus, if Trendar processes the TCH MasterCard through the MasterCard network at these locations, the transaction does not provide the trucking company with data capture and purchase control. This restriction on TCH MasterCard processing hinders Flying J's ability to compete in the trucker fuel card market. Flying J argues that in order for the TCH MasterCard to be fully effective, and therefore attractive to trucking companies, all TCH MasterCard transactions must provide data capture and purchase control.

As discussed more fully below, Comdata interprets the Trendar License as requiring Comdata to configure the Trendar System to treat TCH cards the same way that it treats its own. Accordingly, Comdata was willing to route TCH MasterCard transactions directly through TCH only if TCH secured MasterCard's approval. MasterCard, in turn, refused to agree to financial settlement through private networks except where the merchant entered into a separate agreement with the issuer. Although most merchants have entered into such agreements with Comdata, many have declined to enter such agreements with TCH. According to Comdata, the reason for this discrepancy is that Flying J is a competitor and Comdata (which does not operate truck stops) is not.

In an effort to provide data capture and purchase control in all TCH MasterCard transactions, Flying J filed a motion to enforce the settlement agreement. Flying J argues that at the time of the settlement, Trendar processed the Comdata Fleet Card as a proprietary card; therefore, the Trendar License obligated Comdata to provide universal private processing for TCH MasterCard transactions, regardless of whether the merchant accepts the TCH Fuel Card.

In support of its motion to enforce, Flying J presented two models for TCH MasterCard transactions. The primary model replicated the proprietary processing method used for Comdata MasterCards, which processed the entire transaction over a private network. In the alternative, Flying J proposed a split-transaction or dual-processing model, in which TCH would authorize the transaction over a private network, providing data capture and purchase control, but financial settlement would take place on the MasterCard network. Under the dual-processing model, Trendar would send data to TCH and MasterCard in two different steps, and financial settlement would occur in the same manner as in an ordinary MasterCard transaction.

Flying J's primary model did not conform to MasterCard regulations for proprietary accounts. Joan Hennessey, MasterCard's designated corporate representative, confirmed that Flying J's primary model depicted a proprietary transaction subject to MasterCard's proprietary account rules, which required prior agreement by the merchant. Addressing the dual-processing model, Ms. Hennessey testified that it was not prohibited by MasterCard rules; rather, transmission of authorization data to TCH was "outside of the MasterCard transaction and so it would be outside of our rules." Deposition of Joan Hennessey, JA 1898.

After the Hennessey deposition, Comdata moved for summary judgment, arguing that (1) Flying J failed to secure MasterCard's approval for the primary proposal, and (2) the split-transaction model did not satisfy the requirements of the Trendar License, specifically the requirement that clearing occur "directly through TCH as opposed to . . . the MasterCard network." The court continued the hearing to permit Flying J to ensure compliance with MasterCard procedures. Shortly before the evidentiary hearing resumed, MasterCard confirmed in writing that Flying J's primary model did not meet its proprietary account rules. The dual-processing model fell outside of MasterCard rules. MasterCard noted, however, that it could not require that a merchant participate in the dual-processing arrangement, nor could it require a merchant to provide transaction data to Flying J. MasterCard suggested that the merchant and its acquirer authorize its participation in the dual-processing arrangement.

Because MasterCard rejected its original proposal, Flying J relied exclusively on the dual-processing model at the evidentiary hearing.

The district court held that Comdata had breached its obligations under the Trendar License, including Article 4.2, by failing to implement Flying J's dual-processing model for TCH MasterCard transactions. Order 27, JA 109 (Comdata breached its obligations "by failing promptly to implement a method for direct processing of TCH MasterCard transactions directly through TCH that is acceptable to TCH and does not violate MasterCard rules."). The court found the dual-processing method to be consistent with Comdata's own method of processing the Comdata Fleet Card, rejecting Comdata's argument that proprietary processing of the TCH MasterCard required merchant consent. In its conclusions of law, the court held that Article 4.2's requirement that all transactions be "cleared directly through TCH" included authorization and approval in addition to financial settlement, thereby permitting dual processing. The court granted Flying J's motion to enforce the settlement agreement and ordered Comdata to implement the dual-processing method for TCH MasterCards at all Trendar locations. Comdata appeals.

II. A.

We review the district court's determination of state law de novo. See Salve Regina College v. Russell, 499 U.S. 225, 238-39, 111 S.Ct. 1217, 113 L.Ed.2d 190 (1991); Grant v. Pharmacia Upjohn Co., 314 F.3d 488, 491 (10th Cir. 2002). We review the district court's findings of fact for clear error. "A finding is clearly erroneous when, although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed." United States v. United States Gypsum Co., 333 U.S. 364, 394-395, 68 S.Ct. 525, 92 L.Ed. 746 (1948) (internal quotation marks omitted). "Whether the district court failed to consider or accord proper weight or significance to relevant evidence are questions of law we review de novo." Harvey ex rel. Blankenbaker v. United Transport Union, 878 F.2d 1235, 1244 (10th Cir. 1989) (citing Pullman-Standard v. Swint, 456 U.S. 273, 291, 292, 102 S.Ct. 1781, 72 L.Ed.2d 66 (1982)).

As a preliminary matter, Comdata complains that the district court adopted Flying J's proposed findings of fact and conclusions of law almost verbatim. Regrettably, this appears to be the case. The Supreme Court has criticized the verbatim adoption of findings of fact, "particularly when those findings have taken the form of conclusory statements unsupported by citation to the record." Anderson v. City of Bessemer City, 470 U.S. 564, 572, 105 S.Ct. 1504, 84 L.Ed.2d 518 (1985). The court's wholesale adoption of one party's proposed findings of fact and conclusions of law provides little aid on appellate review, see Everaard v. Hartford Accident Indem. Co., 842 F.2d 1186, 1193 (10th Cir. 1986), particularly in the likely event that the adopted submission takes an adversarial stance.

The district court's adoption of a party's proposed findings does not change the standard of review, however. Though not made by the district judge himself, the findings "are formally his; they are not to be rejected out-of-hand, and they will stand if supported by evidence." United States v. El Paso Nat. Gas Co., 376 U.S. 651, 656, 84 S.Ct. 1044, 12 L.Ed.2d 12 (1964) (citing United States v. Crescent Amusement Co., 323 U.S. 173, 184-85, 65 S.Ct. 254, 89 L.Ed. 160 (1944)); see also Sanpete Water Conservancy Dist. v. Carbon Water Conservancy Dist., 226 F.3d 1170, 1177 n. 7 (10th Cir. 2000) ("[E]ven if we believed the district court improperly adopted [the] proposed findings without reasoned consideration, we would still review the district court's decision under the clearly erroneous standard."). We therefore review the court's findings of fact for clear error.

For its part, Flying J suggests that the district court's familiarity with this case entitles its order to greater deference on appeal. See, e.g., Stone v. City and County of San Francisco, 968 F.2d 850, 856 (9th Cir. 1992); Ferrell v. Pierce, 743 F.2d 454, 461 (7th Cir. 1984). We reject this suggestion as well. It is true that the district court hosted this litigation for almost five years, and we have no doubt that it became excruciatingly well-acquainted with the long-distance trucking industry and the details of Flying J's antitrust claim. The record shows, however, that the question central to this appeal — whether Article 4.2 was intended to authorize a dual-processing model for TCH MasterCard transactions — did not arise until shortly before the evidentiary hearing, well after the parties settled their claims in the underlying suit. Even assuming that the district court's familiarity could increase the already substantial deference owed to findings of fact under the clear error standard, the rationale for such deference would not apply to the issue before us.

B.

This case requires us to reconcile two competing interpretations of the mandate that all TCH Card transactions "shall be cleared directly through TCH as opposed to any third party network . . . to the fullest extent permitted by . . . third party network providers." Trendar License Article 4.2. Comdata contends that the district court erred by failing to determine whether the contract was ambiguous, by refusing to give the term "cleared" its prevailing meaning in the financial industry, and by disregarding Comdata's evidence of intent. Comdata claims further that the district court's ultimate interpretation of the contract was clearly erroneous. Flying J responds that Comdata's interpretation of the contract is unreasonable and, in the alternative, that the court's factual findings are supported by the evidence. We hold that the court interpreted the term "cleared" under an incorrect legal standard, that differences in meaning of the term render Article 4.2 ambiguous, that accordingly the court should have considered Comdata's proffered evidence, and that in light of that evidence the court's factual findings regarding the meaning and intent of the contract are clearly erroneous.

III.

We begin with an argument about whether the district court found the contract ambiguous. Comdata contends that the district court failed to make this threshold determination. Flying J responds that the court explicitly found Comdata's interpretation of the contract unreasonable, and that it follows that, if one of the two possible interpretations is unreasonable, Article 4.2 is not ambiguous. Fortunately, de novo review provides a narrow escape from this tangle of compound ambiguity. Because Flying J and Comdata each advance plausible interpretations of Article 4.2, we find the disputed language to be ambiguous.

A.

The general rules of contract interpretation under state law apply to settlement agreements. See Sackler v. Savin, 897 P.2d 1217, 1220 (Utah 1995). When a court interprets a contract, it must make a threshold determination whether the contract is ambiguous. See Peterson v. Sunrider Corp., 48 P.3d 918, 925 (Utah 2002). A contract is ambiguous if it supports more than one reasonable interpretation. Id; see also Nielsen v. Gold's Gym, 78 P.3d 600, 601 (Utah 2003). Utah law is unsettled on the issue whether the court may go beyond the four corners of the contract to determine whether the contract is ambiguous. Compare WebBank v. Am. Gen. Annuity Serv. Corp., 54 P.3d 1139, 1145 (Utah 2002) ("If the language within the four corners of the contract is unambiguous, the parties' intentions are determined from the plain meaning of the contractual language, and the contract may be interpreted as a matter of law."), and Central Fla. Investments, Inc. v. Parkwest Associates, 40 P.3d 599, 605 (Utah 2002) ("We first look to the four corners of the agreement to determine the intentions of the parties."), with Nielsen, 78 P.3d at 601 (in determining ambiguity, the court may consider "[r]elevant, extrinsic evidence of the facts known to the parties at the time they entered the [contract])" (brackets in original) (quoting Yeargin, Inc. v. Auditing Div. of Utah State Tax Comm'n, 20 P.3d 287 (Utah 2001)), Peterson, 48 P.3d at 918 ("In determining whether a contract is ambiguous the court is not bound to consider only the language of the contract."), and Ward v. Intermountain Farmers' Ass'n, 907 P.2d 264, 268 (Utah 1995) ("When determining whether a contract is ambiguous, any relevant evidence must be considered."). Because both parties follow the expansive view, we assume that the court may look beyond the four corners of the contract to determine ambiguity.

Ambiguity is a question of law. Id. If the contract is ambiguous, the court can admit extrinsic evidence of intent to clarify the meaning of ambiguous terms. Id. If the court determines the contract to be ambiguous and admits extrinsic evidence, the court's interpretation of a disputed term is a finding of fact reviewed for clear error. Nielsen, 78 P.3d at 601 (citing Kimball v. Campbell, 699 P.2d 714, 716 (Utah 1985)).

Flying J contends that consideration of extrinsic evidence transforms the threshold determination of ambiguity into a finding of fact. That is not an accurate statement of Utah contract law. The cases cited by Flying J involve the admission of extrinsic evidence to determine the meaning of ambiguous terms, a question of fact. See Valley Improvement Ass'n, Inc. v. United States Fidelity Guaranty Corp., 129 F.3d 1108, 1115 (10th Cir. 1997); Cavic v. Pioneer Astro Indus., Inc., 825 F.2d 1421, 1424 (10th Cir. 1987) ("[W]hen the trial court resorts to extrinsic testimony to ascertain the meaning of the contractual terms, the interpretation is factual."). In its threshold determination of ambiguity, however, the court decides whether there is anything for the trier of fact to find. Even if the court refers to extrinsic evidence to make that determination, contractual ambiguity presents a question of law that we review de novo. See Peterson, 48 P.3d at 925. We now explain our conclusion that Article 4.2 is ambiguous.

B.

Comdata maintains that the language of Article 4.2 does not permit dual or split transactions through Trendar, but requires that financial settlement, authorization, and approval occur over the same network. It argues that the technical meaning of the term "cleared" for purposes of financial transactions, and in particular as reflected in MasterCard glossary, refers exclusively to financial settlement. The MasterCard glossary defines "clearing" as "[t]he process of exchanging financial transaction details between an acquirer and an issuer to facilitate posting of a cardholder's account and reconciliation of a customer's settlement position." MasterCard, Bankcard Glossary, JA 1151. Relying on this definition, Comdata argues that split transactions violate the requirement that all transactions be cleared directly through TCH as opposed to a third-party network. Comdata thus interprets "to the extent permitted" to mean in as many transactions as permitted by the third-party network provider.

Flying J urges reliance on a more general definition of "clear" found in the Merriam-Webster online dictionary: "5a: to submit for approval clear it with me first b: AUTHORIZE, APPROVE cleared the article for publication: as (1): to certify as trustworthy clear a person for classified information (2): to permit (an aircraft) to proceed usually with a specified action." Merriam-Webster Online Dictionary, at http://www.m-w.com/cgi-bin/dictionary, cited in Order 22, JA104 ("These meanings include the functions of authorizing and approving, in addition to financial settlement."). If clearing is defined in this way, Trendar can transfer authorization and approval data "directly through TCH," while financial settlement takes place in the MasterCard network. Thus, even if a merchant has not agreed to accept the TCH Card, Trendar could send authorization and approval data through a private network, thereby permitting data capture and purchase control on all TCH MasterCard transactions. Thus, Flying J reads "to the extent permitted" to mean as much of the transaction as permitted by MasterCard.

The language of Article 4.2 will bear either party's interpretation. Comdata interprets the provision consistently with its own arrangement with MasterCard. Though Flying J's interpretation is not based on any pre-existing processing model, it too reflects a plausible reading of Article 4.2, it does not violate any specific MasterCard regulation, and it is technically feasible.

The district court agreed with Flying J. The court considered itself bound to "construe contract language in a way that gives effect to the ordinary meaning of words unless the evidence indicates the parties intended to adopt a special meaning." Order 22, JA 104. Finding no evidence demonstrating that the parties intended to define "clear" according to its technical meaning in financial transactions, as illustrated by the MasterCard glossary, the court considered itself bound by the "plain meaning." The district court looked to the dictionary as evidence of plain meaning, concluding that "clear" "include [s] the function of authorizing and approving, in addition to financial settlement." Id. The court reasoned that if clearing involves multiple functions, then Article 4.2 permits different aspects of clearing to occur over different networks. The court rejected Comdata's argument that Article 4.2 did not authorize split transactions as "an unreasonable interpretation of the agreement's language that is inconsistent with the parties' intentions for the Trendar License." Order 24, JA 106.

We do not agree with the district court's application of the plain meaning rule. Under Utah law, if "the contract is unambiguous, the parties' intentions are determined from the plain meaning of the contractual language, and the contract may be interpreted as a matter of law." Green R. Canal Co. v. Thayn, 84 P.3d 1134, 1141 (Utah 2003); see also Grynberg v. Questar Pipeline Co., 70 P.3d 1, 10 (Utah 2003) ("This court interprets unambiguous contracts as a matter of law."). Where there are two plausible meanings — one from ordinary speech and one from the specialized terminology of the relevant industry — the contract is not unambiguous and the plain meaning rule does not apply. See R R Energies v. Mother Earth Indus., 936 P.2d 1068, 1074 (Utah 1997) ("A specialized meaning would create ambiguity because at least two plausible meanings, one `plain' and one `specialized,' would exist."). Giving "cleared" its ordinary dictionary meaning therefore requires a preliminary determination that Article 4.2 is unambiguous.

Even if the plain meaning rule controlled, the definition adopted by the district court is less than plain in the context of Article 4.2. The Restatement of Contracts provides that unless the parties manifest a different intention, "technical terms and words of art are given their technical meaning when used in a transaction within their technical field." Restatement (Second) of Contracts § 201(3)(b); see also Holland v. Brown, 15 Utah 2d 422, 394 P.2d 77, 78-79 (1964) ("When terms used in a contract appear to have a specialized meaning, they must be understood in accordance with the particular connotation they may have acquired in such transactions."). Considering that this lawsuit focuses specifically on MasterCard transactions, MasterCard's own definition might reasonably be consulted to determine the plain meaning of the term in its immediate context. At the very least, Comdata's reliance on the MasterCard glossary should have insulated its interpretation from the charge of unreasonableness.

Flying J does not dispute that the verb "clear" has a specialized meaning in the financial industry; rather, it contends that such usage would be unreasonable in the context of an antitrust settlement. This is an unduly narrow characterization of the issue. It is true that this dispute arises out of an antitrust claim, but the antitrust claim involved financial transactions in the trucker fuel card market. Both parties litigate, at least in part, in their capacity as providers of financial services. The fact that this is an antitrust case therefore does not render irrelevant the specialized meaning of "cleared" in the financial industry.

C.

Interpreting "cleared" in light of its industry-specific meaning does not, however, entirely resolve the ambiguity in Article 4.2. Flying J argues that the Trendar License sanctions dual processing even if "cleared" refers exclusively to financial settlement. Substituting "financial settlement" for "cleared," Article 4.2 requires that all transactions "be [financially settled] directly through TCH as opposed to any third party network . . . to the fullest extent permitted . . . by third party network providers." If MasterCard does not permit financial settlement over the TCH network, the transaction can be settled over the MasterCard network, but nothing in MasterCard's rules, and therefore nothing in Article 4.2, prevents the transfer of other data over the TCH network. Flying J argues, in other words, that if "cleared" refers only to financial settlement, Article 4.2 does not address dual processing; if it does not address it, it does not prohibit it; and if it does not prohibit it, the Trendar License permits dual processing.

We turn, then, to extrinsic evidence of the intended meaning of Article 4.2.

1.

The district court found that Flying J intended the Trendar License to allow TCH cards "effectively to compete with Comdata's proprietary trucker fuel card, including the Comdata MasterCard Fleet Card." Order 5, JA 87. The court found that Comdata failed to produce contradictory evidence:

Comdata did not present evidence at the hearing indicating that the parties did not intend to accomplish this result through the Trendar License. Mr. Sheridan participated in negotiation of the Trendar License but did not offer testimony specifically contradicting that explanation of the parties' intent.

Order 5-6, JA 87-88. Based on what it perceived as a lopsided evidentiary record, the court concluded that

enforcing the Trendar License in a way that requires TCH MasterCard Fleet Card transactions to be cleared directly through TCH, as opposed to the MasterCard I-Net network, at truck stops that do not currently accept the TCH proprietary card as a method of payment . . . is consistent with the reasonable expectations of the parties at the time they entered into their Settlement Agreement and the Trendar License in May 2001.

Order 6, JA 88. The court rejected Comdata's position, which it characterized as "an unreasonable interpretation of the agreement's language that is inconsistent with the parties' intentions for the Trendar License." Order 24, JA 106. We do not agree with this characterization of the record.

In our review of the record, Comdata produced substantial evidence indicating that it did not contemplate or intend that the Trendar License would lead to proprietary processing of TCH MasterCards at unaffiliated merchants, much less that this would be accomplished through a dual-processing model. Comdata's chief counsel, Michael Sheridan, testified that Comdata intended to replicate its own processing model for Flying J: "I thought, Your Honor, that we were allowing them, if MasterCard approved, to send the entire transaction to them and have a proprietary network just like we have." Sheridan Testimony, JA 1632. He specifically disavowed any intention to authorize split transactions: "Section 4.2 was not intended to, and does not, require Comdata to reconfigure the Trendar system to route part of the transaction through TCH and clear other parts of the transaction through the MasterCard network." Sheridan Declaration, JA 1141-42. See also id. at 1141, 394 P.2d 77 ("At no time did I contemplate that Comdata would be required to configure Trendar to route part of a transaction through TCH and another part of the transaction through the MasterCard network."). This constitutes substantial evidence that the parties did not intend to implement the dual processing model, which did not exist at the time the settlement was negotiated and is different from the model used for Comdata's own proprietary cards. The district court's failure to consider Comdata's evidence was a legal error. See Blakenbaker, 878 F.2d at 1244.

2.

The district court found that Flying J's interpretation of the contract would promote the pro-competitive goals of the Sherman Act by creating a network of truck stops where TCH cards provided data capture and purchase control. In the district court's view, this "pro-competitive intent" encompassed data capture and purchase control for all TCH MasterCard transactions at all U.S. truck stops using the Trendar System. It thus concluded that Comdata was bound to implement dual-processing unless it could show that the parties did not intend to restore competition to the trucker fuel card market.

We have no occasion to question the district court's conclusion that Flying J's interpretation of Article 4.2 would better promote the competitive objectives of the antitrust laws. But the issue at this stage is not what would be the most effectual remedy for a proven antitrust violation; the issue is what the parties agreed to in settling the litigation. The parties did not frame their settlement in terms of maximizing competition, but in terms of a specific procedure for processing credit card transactions. The record is unequivocal on one point: both Flying J and Comdata intended the Trendar License to provide Flying J with data capture and purchase control similar to the so-called "Comdata model." JA 1119-20, 1690 (Adams); JA 1632 (Sheridan); Appellee's Br. 33; Appellant's Br. 34. Flying J makes no attempt to dispute this. Appellee's Br. 33. Comdata's own cards were, and are, processed as single transactions. The most straightforward interpretation of Article 4.2, therefore, is that TCH MasterCard transactions would be processed in the same way.

At least at the time of the evidentiary hearing, Comdata and Flying J had different ideas of what the Comdata model entailed. Comdata thought that it referred to a particular procedure: access to the Trendar System, plus data capture and purchase control at affiliated merchants. The main goal of the license, in Comdata's view, was to provide TCH with access to the Trendar System:

Comdata . . . understood that the Plaintiff's goal in litigation and settlement was to have the TCH card accepted over the Trendar System and cleared directly through TCH, if permitted by MasterCard. Indeed, the very title to the operative agreement in this matter is: "Trendar License (TCH Card Access to Trendar)."

Sheridan Declaration, JA 1134. Comdata did not view the license as intended "solely to provide TCH with full data capture, regardless of how transactions were to be cleared or regardless of whether TCH obtained MasterCard's consent." Id. Neither did Comdata anticipate that the Trendar License would require Trendar to split transactions.

Flying J argues that the Comdata model was associated solely with a result: data capture and purchase control at all Trendar locations that accepted MasterCard. Flying J apparently believed that this result was "comparable to the direct processing of the Comdata MasterCard Fleet Card." Order 17, JA 99. Flying J's understanding depended on the assumption that Comdata obtained data capture and purchase control in Fleet Card transactions without merchant consent. See Declaration of J. Phillip Adams para. 18, JA1118 ("My understanding both in May 2001 and now, is that Comdata did not then, and does not now, have specific agreements with truck stops authorizing such private processing of Comdata MasterCard Fleet Card transactions."). Flying J defends this assumption by reference to the testimony of Comdata's General Counsel, who indicated that Comdata's agreements with truck stops do not specifically notify the merchant that Trendar processes the Comdata Fleet Card over Comdata's private network. Based on this testimony, the district court found that

Comdata does not have written agreements in place with the major U.S. truck stops that accept its card (including Pilot, Petro, and Travel Centers of America) by which Comdata explicitly informs those truck stops that it will be privately processing Comdata MasterCard Fleet Card transactions outside the MasterCard I-Net network or explicitly obtains their permission for such private processing. Instead, the truck stop merchant agreements on which Comdata relies to argue that it has contracts for private card processing in place with truck stops, are the standard form `service center' agreements by which truck stops agree to accept Comdata products including Comdata's proprietary (non-MasterCard) card.

Order 18, JA100. The district court found "no evidence that Comdata has such written authorizations in place for its own direct processing through Trendar of MasterCard Fleet Card transactions." Order 17, JA 99. If Comdata did not have specific agreements authorizing proprietary Comdata Fleet Card transactions, Flying J argues it also need not obtain merchant consent to proprietary TCH MasterCard transactions.

Flying J's reliance on the lack of an explicit agreement with the merchant attempts to sidestep the evidence that Comdata Fleet Cards provided data capture and purchase control only when the merchant had agreed to accept its proprietary cards. MasterCard's representative testified that Comdata processed transactions outside the MasterCard network based on the exception for proprietary accounts. MasterCard Bylaws and Rules, October 2002, Rule 6.6, JA 546. The proprietary account exception required that the merchant agree to accept the card issuer's proprietary card before the issuer's fleet card could be processed privately. See id. Rule 6.6.1, JA 546; Rule 8.05, Dec. 2001, JA 539; Hennessy Deposition, JA 1902. There was no contrary evidence. It follows that Comdata did not enter into specific agreements to process Comdata Fleet Cards over its own network because it would have been redundant to do so. The merchant had already agreed to accept Comdata's proprietary card; therefore, it had consented to proprietary processing. The district court's finding that Comdata provides data capture and purchase control in MasterCard transactions without notice to merchants is thus without support in the record.

Flying J's response — that Comdata did not and cannot show a single merchant that does not accept the Comdata Card — misses the point. Under the circumstances, widespread, even universal, acceptance of Comdata's proprietary card does not show that Comdata did not have to obtain the merchant's consent to get proprietary processing; it proves only that Comdata always got it. Comdata offers an explanation for the Comdata Fuel Card's popularity: unlike Flying J, Comdata is not a competitor in the truck stop industry, and unaffiliated merchants therefore are more willing to accept its card. Far from proving Flying J's point, this supports the inference that merchant consent was central to Comdata's commercial arrangements and therefore to the Comdata model. Flying J does not produce any evidence to the contrary. The court therefore clearly erred in finding that the parties intended the Trendar License to have the meaning urged by Flying J.

3.

If Comdata's processing model involved unitary processing and merchant consent, the meaning of Article 4.2 depends in part on whether Flying J knew or had reason to know of these characteristics at the time of the settlement agreement. Flying J and Comdata attribute different meanings to Article 4.2, creating an apparent misunderstanding regarding a key term of the Trendar License. Where the parties assign different meanings to a term,

it is interpreted in accordance with the meaning attached by one of them if at the time the agreement was made

(a) that party did not know of any different meaning attached by the other, and the other knew the meaning attached by the first party; or

(b) that party had no reason to know of any different meaning attached by the other, and the other had reason to know the meaning attached by the first party.

Restatement (Second) of Contracts § 201(2). If Flying J knew or had reason to know that Comdata understood Article 4.2 to mean that Trendar would process TCH MasterCards in the same manner as Comdata Fleet Cards — through unitary transactions — then Article 4.2 must be interpreted accordingly.

At the time of the settlement, neither party had reason to expect that Article 4.2 would result in a dual-processing arrangement. Flying J concedes that it did not conceive of the dual-processing model until after the parties entered the Trendar License. Kevin Farnsworth, a TCH employee who was involved in programming Trendar to accept TCH cards, testified that Flying J originally requested that the TCH MasterCard be processed exclusively through the TCH network. Testimony of Kevin W. Farnsworth 167:11-25, JA 1588. Ted Jones, the President of TCH, testified that he was not aware of any split transactions over the Trendar System. Testimony of Ted David Jones 149:9-21, JA 1570. At the time of the settlement, therefore, Flying J expected that TCH MasterCards would be processed exclusively through TCH rather than split between the TCH and MasterCard networks.

Comdata likewise had reason to expect that the Trendar License would be limited to unitary processing based on its own arrangement with MasterCard. As previously noted, MasterCard's representative testified that Comdata processed transactions outside the MasterCard network based on the exception for proprietary accounts. MasterCard Bylaws and Rules, October 2002, Rule 6.6, JA 546. The proprietary account exception required that the merchant agree to accept the card issuer's proprietary card before the issuer's fleet card could be processed privately. See id. Rule 6.6.1, JA 546; Rule 8.05, Dec. 2001, JA 539; Hennessy Deposition, JA 1902. Thus, according to MasterCard, Comdata's own procedures are consistent with the unitary processing model. Comdata's arrangement clarifies the ambiguous language of Article 4.2.

Flying J counters with the argument that the parties intended to achieve a particular result; therefore, the particulars of Comdata's own processing model do not matter. Flying J draws a distinction between the actual Comdata model and an arrangement similar to the Comdata model, which would provide Flying J with "the same real-time data capture and purchase control functionality for its TCH MasterCard at truck stop locations that use the Trendar System that Comdata was providing to the Comdata MasterCard Fleet Card through the Trendar System." Adams Declaration, JA 1119-20; see also JA 1690 ("[W]hat we contemplated in the settlement was that we were going to be able to process transactions the way Comdata was processing Comdata MasterCard transactions.").

There is evidence in the record, however, that suggests Flying J knew or had reason to know that Comdata intended Article 4.2 transactions to replicate the procedure used in Comdata Fleet Card transactions. In his declaration submitted to the district court, Flying J's president described his knowledge of Comdata's arrangement:

As of May 2001, I knew that the Trendar system was programmed to process Comdata MasterCard Fleet Card transactions outside the MasterCard network. Thus, . . . the Trendar system would automatically route the transaction directly to Comdata — instead of through MasterCard's network — so it could be cleared directly through Comdata just like transactions involving the Comdata Fuel Card.

Declaration of J. Phillip Adams, April 4, 2003, at 3, JA 842. Mr. Adams's statement supports the inference that Flying J actually understood "direct" clearing — the term used in Article 4.2 — to be equivalent to exclusive clearing — the meaning urged by Comdata. In other words, it understood "direct" clearing to mean that the entire transaction would be routed through Comdata's network, not split between different networks. At the very least, Flying J had reason to know Comdata's intended meaning. Even if Flying J thought that Article 4.2, as written, entitled it to data capture and purchase control in all TCH MasterCard transactions, regardless of merchant consent, there is evidence that it had reason to know Comdata believed the contrary.

Both parties anticipated that Article 4.2 would follow the Comdata model of MasterCard processing. The record shows that Comdata's arrangement with MasterCard followed a specific MasterCard policy for proprietary accounts, which involved unitary transactions and merchant consent. There is evidence that Flying J had reason to know that Comdata intended these limits to apply to Article 4.2. Accordingly, we hold that the district court clearly erred in finding that the parties intended Article 4.2 to require proprietary TCH MasterCard transactions at all Trendar locations, regardless of merchant consent, by any feasible means.
