    BRORBY, Circuit Judge.
    This appeal involves the interpretation of a contract between Appellant,
    Gamble, Simmons and Company (“Gamble Simmons”) and Appellee, Kerr-
    McGee Corporation (“Kerr-McGee”), for tax consulting services. Gamble
    Simmons claims Kerr-McGee undercompensated the company for an audit review
    it performed and now brings this consolidated appeal challenging the district
    court’s grant of summary judgment and an award of attorneys’ fees in favor Kerr-
    McGee. We exercise jurisdiction pursuant to 
    18 U.S.C. §1291
    , and affirm in
    part, reverse in part, and remand.
    I. Introduction
    Gamble Simmons is a tax consulting firm specializing in the review and
    evaluation of audits by state taxing authorities. In September 1988, shortly after
    the Louisiana Department of Revenue and Taxation (“the Department”) issued
    Kerr-McGee a “Notice of Tax Due,” including tax, interest and penalties based
    on Sales and Use tax assessments for the years 1982-1984, Gamble Simmons
    approached Kerr-McGee with an offer to review the company’s records and
    determine whether it properly owed the taxes assessed, and whether the amount
    of tax could be reduced. Concerned about its tax liability, Kerr-McGee accepted
    Gamble Simmons’ offer; and, in May 1991, the parties entered a contract
    -2-
    (hereinafter “contract” or “agreement”) under which Gamble Simmons agreed to
    perform its tax consulting services for Kerr-McGee. The payment provisions of
    the agreement specifically obligate Kerr-McGee to pay Gamble Simmons “an
    amount equal to forty percent (40%) of the amount, if any, by which the total
    amounts of taxes, penalties and/or interest ... heretofore paid by Kerr-McGee ...
    and/or assessed by the Department ... are refunded or reduced.”
    Gamble Simmons performed under the agreement for the next three years,
    ultimately obtaining a very favorable outcome for Kerr-McGee. As a result of
    Gamble Simmons’ efforts, the Department admitted Kerr-McGee owed no
    additional taxes or interest for the years 1982-1984 and that it had actually
    overpaid taxes in the amount of $1,447,985. The Department subsequently
    refunded a portion of that amount directly to Kerr-McGee and applied the
    balance to offset taxes and interest Kerr-McGee owed for 1985-1987.
    After obtaining the favorable result, Gamble Simmons billed Kerr-McGee
    $1,095,439 for its services. However, Kerr-McGee disputed the charges and paid
    Gamble Simmons only $665,418, a figure Kerr-McGee arrived at through its own
    independent calculations. The difference between the parties’ figures resulted
    from their conflicting interpretations of certain contract provisions and
    -3-
    disagreement over what amounts to include in determining the contingency fee
    owed to Gamble Simmons. After settlement efforts failed, Gamble Simmons
    filed suit in the district court of Harris County, Texas to recover the difference in
    the amount claimed and the amount Kerr-McGee actually paid. Kerr-McGee
    subsequently removed the diversity action to federal court in the Western District
    of Oklahoma.
    Gamble Simmons’ final amended complaint stated several alternative
    causes of action. First, Gamble Simmons argued that by choosing to take a
    refund of tax and interest generated by its efforts rather than applying the credit
    to subsequent years’ tax liability – which would have resulted in reduced penalty
    and interest liability for those years – Kerr-McGee deprived Gamble Simmons of
    its forty percent fee on the savings. Second, Gamble Simmons alleged, as an
    alternative to its first cause of action, that Kerr-McGee received total benefits
    from Gamble Simmons’ efforts in the amount of $2,738,597.53 in tax, interest,
    and penalty reductions and refunds, and that the contract entitles Gamble
    Simmons to forty percent of those benefits. Specifically, Gamble Simmons
    claimed its compensation should include statutory interest paid to Kerr-McGee by
    the Department as part of the refund for overpayment. In its third cause of
    action, Gamble Simmons asserted, in the alternative, that because Kerr-McGee
    -4-
    representatives admitted the contract entitles Gamble Simmons to its percentage
    share of interest included as part of the refund, and some of Kerr-McGee’s own
    calculations indicate it owed Gamble Simmons $982,156.70, Kerr-McGee must
    pay Gamble Simmons the balance due of $316,738.60 plus pre-judgment interest.
    Fourth, as an alternative to its third cause of action, Gamble Simmons asserted
    that based on the actual refund Kerr-McGee received from the Department of
    $1,274,732.10, the correct amount payable to Gamble Simmons based on Kerr-
    McGee’s own calculation methods was $1,016,917.29, leaving an unpaid balance
    of $351,499.19 plus pre-judgment interest. Fifth, Gamble Simmons argued that
    even if the court found the contract did not permit it to share in interest Kerr-
    McGee received as part of the refund from the Department, the agreement at least
    entitles Gamble Simmons to its fee on the benefits conferred minus the interest.
    Gamble Simmons asserted this alternative amount was $787,498.94, and
    requested relief in the amount of the deficiency, $122,080.84, plus pre-judgment
    interest. Finally, in its sixth cause of action, Gamble Simmons contended Kerr-
    McGee breached the contract by refusing to allow Gamble Simmons to review
    Kerr-McGee’s books for periods beyond 1982-1984, and as a result, Gamble
    Simmons suffered the loss of fees it could have generated through reviewing later
    years’ records.
    -5-
    In September 1995, both parties filed simultaneous cross-motions for
    summary judgment to resolve Gamble Simmons’ claims. The district court issued
    an order on June 20, 1996 in which it addressed the parties’ motions and granted
    summary judgment in favor of Gamble Simmons in the amount of $769,850 less
    payments already made by Kerr-McGee. In reaching this conclusion, the district
    court decided the contract is not ambiguous and does not entitle Gamble
    Simmons to a portion of the interest paid to Kerr-McGee as part of the refund for
    overpayment. However, this initial interlocutory order did not dispose of all the
    issues in the case, and the parties subsequently filed additional cross-motions for
    summary judgment pertaining to the remaining issues.
    On June 4, 1997, the district court issued a comprehensive Memorandum
    Opinion and Order covering the remaining claims. The court decided the
    contract entitles Gamble Simmons to forty percent of the 1982-1984 refund
    generated through its efforts; but, the agreement does not allow Gamble Simmons
    to collect forty percent of the incidental interest and penalty reductions in
    subsequent years resulting from the application of 1982-1984 tax refund to the
    later periods. The district court based its decision primarily on the fact that the
    incidental interest or penalty savings Kerr-McGee realized on the 1985-1987
    audit were not based directly on Gamble Simmons’ work product or information.
    -6-
    Additionally, the district court ruled the contract between the parties only
    contemplated a single audit involving the examination of Kerr-McGee’s 1982-
    1984 records. The court refused to grant Gamble Simmons’ request to review
    Kerr-McGee’s 1985-1991 records for any other purposes.     1
    After the court’s summary judgment rulings, the parties were unable to
    reach an accord on a proposed judgment as ordered by the court. Consequently,
    on October 27, 1997, the district court issued its own final judgment granting
    Kerr-McGee’s motion for summary judgment and awarding Gamble Simmons
    $665,418 for its services – the exact amount Kerr-McGee had already paid.
    On appeal, Gamble Simmons raises several issues. First, it contends the
    district court erred in finding Gamble Simmons was not entitled to a percentage
    of the interest the Department paid to Kerr-McGee as part of a refund for
    overpayment of taxes. Second, Gamble Simmons claims the district court should
    have considered extrinsic evidence it submitted regarding the formation of the
    agreement, the parties’ subjective interpretations of the agreement, and certain
    1
    The court noted the parties allowed Gamble Simmons to examine other
    years’ records but only for purposes related to the 1982-1984 audit of Sales and
    Use taxes.
    -7-
    alleged admissions made by Kerr-McGee representatives regarding amounts owed
    to Gamble Simmons. Third, Gamble Simmons argues the district court erred
    when it decided the agreement only covered the audit of tax years 1982-1984.
    Fourth, Gamble Simmons claims the district court should have granted its Motion
    to Settle Contents, entered final judgment in its favor, and granted its motion for
    an evidentiary hearing on the contract interpretation issues. Finally, in a
    consolidated appeal, Gamble Simmons disputes the district court’s award of
    attorneys’ fees to Kerr-McGee.
    II. Standard of Review
    Because this appeal is based solely on the district court’s summary
    judgment rulings, we review the case   de novo , employing the same legal
    principles as the district court and construing the factual record and the
    reasonable inferences therefrom in the light most favorable to the party opposing
    summary judgment.    See Byers v. Albuquerque     
    150 F.3d 1271
    , 1274 (10th Cir.
    1998); Kane v. Capital Guardian Trust Co.      , 
    145 F.3d 1218
    , 1221 (10th Cir.
    1998). Summary judgment is appropriate if the record shows “there is no
    genuine issue as to any material fact and that the moving party is entitled to a
    judgment as a matter of law.” Fed. R. Civ. P. 56(c). An issue of material fact is
    genuine only if the nonmovant presents facts sufficient to show that a reasonable
    -8-
    jury could find in favor of the nonmovant.         Anderson v. Liberty Lobby, Inc.   , 
    477 U.S. 242
    , 248 (1986); see also Lawmaster v. Ward , 
    125 F.3d 1341
    , 1346-47
    (10th Cir. 1997). If our inquiry reveals no genuine issue of material fact in
    dispute, then we review the case to determine if the district court correctly
    applied the substantive law.   Kaul v. Stephan , 
    83 F.3d 1208
    , 1212 (10th Cir.
    1996).
    III. Contract Claims
    The present case requires us to ascertain the intent of the parties as
    expressed under the terms of their agreement with regard to Gamble Simmons’
    compensation. We must decide what portion of the tax reduction and refunds
    attributable to Gamble Simmons’ efforts are properly included as elements of its
    contingency fee under the agreement and what tax years the agreement
    encompasses.
    As a preliminary matter, we emphasize the law of the forum where the
    contract is made or is to be performed generally governs contract actions of this
    sort. Bohannan v. Allstate Ins. Co. , 
    820 P.2d 787
    , 793 (Okla. 1991);         see also
    
    Okla. Stat. tit. 15, § 162
    . In this diversity action the parties agree, and we find,
    the law of Oklahoma controls our inquiry.
    -9-
    In Oklahoma, a comprehensive statutory scheme governs contractual
    agreements. See 
    Okla. Stat. tit. 15, §§ 151
     - 178. These statutes provide that
    whenever possible we must give effect to mutual intent of the parties as
    expressed in the language of the contract, so long as it is unambiguous on its face
    and there exists no “fraud, accident, or pure absurdity” affecting the agreement.
    Public Serv. Co. of Okla. v. Burlington Northern R.R. Co.   , 
    53 F.3d 1090
    , 1097
    (10th Cir. 1995); 
    Okla. Stat. tit. 15, § 154
    . If the contract is ambiguous, then we
    may resort to extrinsic evidence, including the subsequent statements and actions
    of the parties, in order to construe the agreement.   See Pierce Couch Hendrickson
    Baysinger & Green v. Freede , 
    936 P.2d 906
    , 912 (Okla. 1997). However, if the
    contract is unambiguous its language is the only legitimate evidence of what the
    parties intended, see Mercury Inv. Co. v. F.W. Woolworth Co.    , 706 P.2d, 523m
    529 (Okla. 1985), and we will not rely on extrinsic evidence to vary or alter the
    plain meaning. See, e.g., Empire Oil & Ref. Co. v. Babson    , 
    77 P.2d 682
    , 684
    (Okla. 1938) (ruling that resort to extraneous evidence is proper only if the
    contract is ambiguous.)
    A.     The Question of Ambiguity
    Because Gamble Simmons seeks to prove the parties’ intent by utilizing
    extrinsic evidence, we must determine the admissibility of such evidence by first
    -10-
    deciding as a matter of law whether the terms of the contract between Kerr-
    McGee and Gamble Simmons are ambiguous.           Kerr-McGee Corp. v. Admiral Ins.
    Co., 
    905 P.2d 760
    , 762 (Okla. 1995). Oklahoma law states “[a] contract is
    ambiguous if reasonably susceptible of more than one interpretation.”     Williams
    v. Shearson Lehman Bros., Inc ., 
    917 P.2d 998
    , 1004 (Okla. Ct. App. 1996), or
    “through vagueness of expression it has a double meaning.”       See Cinocca v.
    Baxter Labs., Inc. , 
    400 F. Supp. 527
    , 532 (E.D. Okla. 1975). In other words, a
    contract is ambiguous if reasonably intelligent persons, on reading the contract,
    would honestly differ as to its proper meaning.    See United States Fidelity &
    Guar. Co. v. Guenther , 
    281 U.S. 34
    , 37 (1930).
    In this case, we acknowledge the parties’ basic disagreement over the
    interpretation of several provisions of the contract. However, the mere fact that
    the parties disagree about the meaning of a contract or argue for a different
    construction does not necessarily make the agreement ambiguous. A party cannot
    manufacture an ambiguity in a contract that is clear on its face merely by filing a
    lawsuit contesting its meaning or claiming an alternative interpretation.
    Moreover, if a contract is plain and unambiguous, it does not become ambiguous
    because its operation will work a hardship upon one of the parties and a
    corresponding advantage to the other. The dispositive factor in our analysis is
    -11-
    not whether the parties disagree or inequity results, but whether an examination
    of the entire agreement reveals more than one reasonable interpretation.
    Bartmann v. Maverick Tube Corp ., 
    853 F.2d 1540
    , 1545 (10th Cir. 1988)
    (finding “[a] term is unambiguous where it is reasonably and fairly susceptible of
    only one meaning”).
    In order to decide whether the contract is ambiguous, we look at the whole
    contract and construe the words as they are “understood in their ordinary and
    popular sense, rather than according to their strict legal meaning, unless used by
    the parties in a technical sense, or unless a special meaning is given to them by
    usage.” 
    Okla. Stat. tit. 15, §160
    . In the present case, the parties’ intent is
    apparent, regardless of whether the terms are read in their ordinary, legal, or
    technical sense. The compensation clause at the heart of this contract dispute
    plainly and succinctly enumerates the elements of tax savings properly included
    in calculating Gamble Simmons’ contingency fee, as well as the tax years for
    which Gamble Simmons is permitted to perform its services. Although Gamble
    Simmons urges us to find the terms ambiguous and thereby allow the introduction
    of extrinsic evidence tending to contradict the express contract language, we
    decline to indulge its strained construction of the agreement to “create and then
    construe an ambiguity so as to import a favorable consideration to either party
    -12-
    than that expressed in the contract.”    Kerr-McGee, 905 P.2d at 763 (internal
    quotation marks & citation omitted);     see also Max True Plastering Co. v. United
    States Fidelity & Guar. Co. , 
    912 P.2d 861
    , 869 (Okla. 1996) (refusing to indulge
    in constrained interpretations of contracts to find ambiguity). Our review of the
    record reveals contract terms that are unambiguous, readily understood, and not
    “fairly susceptible” of various interpretations. Therefore, in the absence of any
    “fraud, deception, or unfair dealing” by either party in procuring the agreement,
    or “legal impediment shown” that prevented the parties from entering into the
    contract and expressing it in language of their own choosing, we will not resort
    to extrinsic evidence to interpret or revise the agreement.   Northwestern Oil &
    Gas Co. v. Branine , 
    175 P. 533
    , 534 (Okla. 1918).      2
    B.     Applying the Terms of the Contract
    Having decided the contract is unambiguous and a clear reflection of the
    parties’ intentions, we now apply the terms of the contract to resolve the
    2
    Because we find the terms pertaining to contested issues in this lawsuit
    unambiguous, we ignore Gamble Simmons’ proposed evidence of telephone
    conversations with Kerr-McGee representatives and any other extrinsic evidence
    tending to disturb or alter the plain meaning of the contract terms. See
    Prudential Ins. Co. v. Glass, 
    959 P.2d 586
    , 594 (Okla. 1998) (ruling that if a
    contract is complete in itself and is unambiguous when viewed in its entirety, "its
    language is the only legitimate evidence of what the parties intended").
    -13-
    contested contractual issues in this case. The agreement plainly reveals the
    parties’ intent with regard to both the amounts to include in calculating Gamble
    Simmons’ contingency fee and the permissible scope of its right to review Kerr-
    McGee’s records.
    1.    Refund Amounts Properly Included the Contingent Fee
    In terms of compensation, the contract states that Gamble Simmons should
    receive
    an amount equal to forty percent (40%) of the amount, if any, by
    which the total amounts of taxes, penalties and/or interest calculated
    through the date of this Agreement heretofore paid by Kerr-McGee
    to its vendors, the State of Louisiana and/or assessed by the
    Department but remain unpaid as of the date hereof, are refunded or
    reduced ....
    (Emphasis added). Interpreting this clause, the district court correctly decided
    the agreement entitles Gamble Simmons to no more compensation for its services
    than forty percent of any refund or reduction in taxes previously paid or assessed
    as part of the 1982-1984 audit. In other words, the statutory interest the
    Department included as part of the refund to Kerr-McGee is not an amount
    subject to Gamble Simmons’ contingency fee under the contract because it does
    not reflect an amount paid by Kerr-McGee or assessed against it for the years
    1982-1984. The statutory interest actually represents a reasonable return on the
    -14-
    amount the Department erroneously charged Kerr-McGee in prior years.
    Nowhere does the contract contemplate Gamble Simmons sharing in this statutory
    interest either expressly or impliedly. We note, however, the contract provides
    Gamble Simmons should receive forty percent of the refund or reduction based
    on the total amount of 1982-1984 taxes overpaid or assessed in 1982-1984,
    regardless of whether the overpayment is actually repaid directly to Kerr-McGee
    or applied to later years’ tax liability – as long as those amounts are based on
    Gamble Simmons’ efforts during the its review of the 1982-1984 audit.
    We find Gamble Simmons’ counter-arguments on this point unavailing.
    Our interpretation of the contract does not, as Gamble Simmons contends, render
    the term “refund” in the contract a nullity. Rather, it reflects the intent of the
    parties as clearly expressed in the terms of the contract by giving effect to the
    meaning of “refund” as used in conjunction with other language in the contract to
    limit Gamble Simmons’ contingency fee to refund amounts “heretofore paid” by
    Kerr-McGee or “assessed” by the Department. Moreover, our reading of the
    contract does not have the effect of eliminating the reduction of assessed interest
    as part of Gamble Simmons’ contingent compensation. On the contrary, we
    recognize the contract clearly requires Kerr-McGee to pay Gamble Simmons its
    contingent share of reductions in interest assessed against Kerr-McGee for the
    -15-
    1982-1984 audit period. The “interest” not subject to Gamble Simmons’
    contingent fee is the statutory interest awarded to Kerr-McGee as part of the
    refund for overpayment.
    We are similarly unpersuaded by Gamble Simmons’ argument asserting
    that because Louisiana Rev. Stat. Ann. § 47:1624(A) mandates the payment of
    interest as part of a Department refund for tax overpayments, the statute must be
    read into Gamble Simmons’ contract with Kerr-McGee to make the term “refund”
    include the statutory interest. Gamble Simmons’ argument on this point refers to
    a sound legal principle of contract construction which states “      unless the contract
    discloses a contrary intention     , an existing statute will be read into it to the same
    effect as an express provision.”      United States v. Essley,   
    284 F.2d 518
    , 520 (10th
    Cir. 1960) (emphasis added). Nevertheless, we question the applicability of this
    principle in the present case because the contract expresses an intention contrary
    to the statute. Again, we emphasize the terms of the contract expressly limit
    Gamble Simmons’ contingent share to amounts “heretofore paid” or “assessed”
    that are “refunded or reduced.” In light of this limiting language in the contract
    that discloses an intention not to include the statutory interest as part of the
    refund, we decline to interpret the term refund as used in the contract to
    incorporate Louisiana Rev. Stat. Ann. § 47:1624(A).
    -16-
    All other arguments aside, the basic problem with Gamble Simmons’
    position is that it urges us to imply contract provisions that simply are not there.
    For example, in its brief Gamble Simmons states that “paragraph 4 of the
    Agreement clearly contemplates that to the extent Kerr-McGee      received any
    benefit in reduction of taxes, interest and penalties, Gamble Simmons’ fee would
    be 40% thereof.” (Emphasis added). However, Gamble Simmons’ statement
    does not reflect the agreement of the parties as expressed in the unambiguous
    terms of the contract. The agreement between the parties is not to pay Gamble
    Simmons a portion of any   benefit Kerr-McGee received through Gamble
    Simmons’ efforts, but a contingent interest in the amount by which Gamble
    Simmons’ services resulted in the refund or reduction of taxes, interest, and/or
    penalties previously paid by Kerr-McGee or assessed by the Department during
    the audit period. The contract enumerates a specific range of compensable
    interests, not the wide-open “benefit” approach Gamble Simmons advocates.
    2.     Application of the Refund to Subsequent Years’ Tax Liability
    We also agree with the district court’s assessment with regard to the
    application of the contract to later years’ taxes. Gamble Simmons is only entitled
    to its contingent share of the refund or reduction in amounts previously paid or
    assessed for tax years 1982-1984, whether such amounts are actually paid directly
    -17-
    to Kerr-McGee or applied to later years’ taxes.
    In addition to its share of the 1982-1984 refund amounts applied to Kerr-
    McGee’s 1985-1987 tax liability, Gamble Simmons also claims Kerr-McGee
    owes it forty percent of the interest reductions Kerr-McGee realized in the 1985-
    1987 audit period through application of the 1982-1984 refund. However,
    Gamble Simmons’ claim again contravenes the language of the contract. Our
    reading of the agreement persuades us that Gamble Simmons is entitled to
    compensation only for whatever amount its efforts       directly caused the
    Department to refund or reduce taxes, interest and penalties previously paid by or
    assessed against Kerr-McGee with regard to the 1982-1984 audit. The indirect,
    incidental benefit of interest reduction that occurred as a result of the
    Department’s unilateral application of a portion of the 1982-1984 refund to Kerr-
    McGee’s later years’ tax liability is not subject to Gamble Simmons’ forty
    percent contingent fee because the interest reduction is not the    direct result of
    Gamble Simmons efforts with regard to its 1982-1984 audit review. In other
    words, the incidental benefit to Kerr-McGee for the interest reduction in 1985-
    1987 represents the consequence of the Department’s decision to apply the 1982-
    1984 refund to subsequent audits –     not the result of Gamble Simmons’ efforts.
    -18-
    This result makes sense if we hypothesize for a moment about what amount
    Gamble Simmons would have received if the Department had refunded the entire
    sum directly to Kerr-McGee and not applied any amount toward subsequent tax
    liabilities. Under those circumstances, Gamble Simmons would still receive its
    forty percent share of the refunded amount as provided by the contract, but it
    would have no further claim for compensation from any incidental or secondary
    financial benefit Kerr-McGee might enjoy through the productive use of the
    refund. For example, if Kerr-McGee took the refund and immediately paid off an
    outstanding debt, Gamble Simmons clearly would not have a viable claim for a
    share of the interest savings Kerr-McGee would realize from the transaction.
    Likewise, if Kerr-McGee took the refund and immediately paid its tax liability
    for the 1985-1987 audit, Gamble Simmons would have no claim to the
    accompanying reduction in interest on the tax liability. We see no difference of
    any significance between these hypothetical examples and what actually
    happened in the present case. The Department’s unilateral decision to apply a
    portion of the 1982-1984 refund to the later audit has the same effect as if Kerr-
    McGee itself had received the refund and immediately paid its 1985-1987 tax
    liability.
    If the contract had stated the parties’ intention for Gamble Simmons to not
    -19-
    only share in the reduction or refund of taxes, penalties or interest Kerr-McGee
    realized from Gamble Simmons efforts with regard to the 1982-1984 audit,        but
    also whatever incidental reduction resulted from the application of the 1982-1984
    refund to later years’ tax liability, then Gamble Simmons would have a viable
    claim for its share of the incidental benefit. However, understood in its entirety,
    the contract simply does not evidence Gamble Simmons’ right to share in the
    secondary benefits realized by Kerr-McGee through the Department’s unilateral
    application of the 1982-1984 refund to the 1985-1987 audit. Therefore, we
    affirm the district court’s conclusion that refunds and reductions in taxes,
    penalties, and interest previously paid or assessed in 1982-1984 are subject to
    Gamble Simmons’ forty percent fee, but the incidental reductions in interest or
    penalties resulting from the application of the 1982-1984 refund are not.   3
    3
    Gamble Simmons makes a very puzzling argument in its brief contesting
    the district court’s finding on this issue we feel compelled to address. It asserts
    that if the district court’s conclusion regarding the interpretation of the contract is
    taken to its logical extreme, it would mean Gamble Simmons would receive no
    compensation if the entire refund it generated had been applied to subsequent
    years’ taxes, interest, and penalties. If this is Gamble Simmons’ understanding of
    the district court’s ruling, we believe it has misinterpreted the findings. Our
    decision to deny Gamble Simmons any compensation for benefits realized by
    Kerr-McGee from the application of a portion of the refund to subsequent years’
    taxes under the terms of the contract, in no way means Gamble Simmons would
    get nothing for its services if the refund was applied entirely to subsequent years.
    On the contrary, Gamble Simmons is entitled to everything the contract allows –
    forty percent of taxes, interest, and/or penalties previously paid or assessed during
    the 1982-1984 audit period which the Department refunded or reduced because of
    Gamble Simmons efforts. As long as the refund represents such amounts, Gamble
    -20-
    3.      Access to Later Years’ Records
    To the extent Gamble Simmons requests access Kerr-McGee’s records for
    later years’ taxes, we find the terms of the contract do not so provide. The
    agreement only allows
    Gamble Simmons to review Kerr-McGee’s books and records with
    respect to transactions involving Louisiana Sales and Use Taxes for
    the applicable statutory periods for the purpose of evaluating said
    audits and assessments and advising Kerr-McGee with respect
    thereto ....
    Although, viewed in isolation, this provision contains no express limitations on
    Gamble Simmons’ asserted right to audit Kerr-McGee’s records, we must
    interpret it in light of the entire contract.     See 
    Okla. Stat. Ann. tit. 15, § 157
    (1991) ("The whole of a contract is to be taken together, so as to give effect to
    every part, if reasonably practicable, each clause helping to interpret the
    others."). In addition to the clause noted, the contract also contains other
    provisions that lend context and perspective to our application. The opening
    recitals are especially helpful to objectively analyze the intent of the parties with
    regard to the scope of the audit. They discuss the Department’s audit of Kerr-
    Simmons is entitled to its share whether the refund is paid directly to Kerr-McGee
    or applied to subsequent years. What Gamble Simmons does not share in as part
    of its compensation, is the resulting incidental tax, penalty and/or interest
    reduction realized through application of the refund to later tax years because that
    reduction is not directly attributable to services Gamble Simmons performed in its
    review of the 1982-1984 audit.
    -21-
    McGee’s Sales and Use taxes paid in 1982-1984, and imply that the Department’s
    audit was the driving force behind Kerr-McGee’s decision to contract for Gamble
    Simmons’ services. Using these initial recitals as a backdrop, we find the only
    reasonable construction of the subsequent terms of the contract is that the parties
    intended to limit the scope of Gamble Simmons’ work to the 1982-1984 audit.
    When the contract refers specifically to “the applicable statutory periods”, we
    believe that clause plainly makes reference to the aforementioned 1982-1984
    audits discussed in the opening recitals of the contract, not “applicable statutory
    periods” in the some general sense. Accordingly, we find the agreement contains
    no compelling support for Gamble Simmons’ argument that it is entitled to
    examine Kerr-McGee’s records for additional statutory periods, other than where
    necessary as incidental to its audit for 1982-1984.   4
    4
    Moreover, even if we strained the language to find the contract allowed
    Gamble Simmons to review later tax years, in no way does the contract indicate
    the parties mutually agreed to have Gamble Simmons perform its services and
    receive compensation for tax years beyond the 1982-1984 period specifically
    discussed in the opening recitals of the contract.
    -22-
    IV. Post-Summary Judgment Proceedings
    A.     Background
    Following the district court’s June 4, 1997 Memorandum & Order granting
    Kerr-McGee’s motion for summary judgment, the court instructed the parties to
    submit a proposed final judgment reflecting the court’s ruling. However,
    negotiations failed and the parties were unable to reach an accord regarding the
    content of the final judgment. The parties essentially disagreed about how to
    calculate Gamble Simmons’ final compensation, while giving effect to the district
    court’s interpretation of the contract. The major point of contention was whether
    to exclude from Gamble Simmons’ compensation certain refunds the Department
    made to Kerr-McGee of payments Kerr-McGee rendered after the execution of
    the agreement (hereinafter “post-agreement payments”). Because the parties
    could not agree, Gamble Simmons filed a motion to settle the contents of the
    final judgment and a request for an evidentiary hearing on the compensation
    calculation issue. After consideration of the parties’ arguments, the district court
    denied Gamble Simmons’ post-summary judgment motion to settle contents and
    request for an evidentiary hearing in an order dated October 27, 1997. In its
    order, the district court stated its summary judgment orders already resolved all
    the issues presented, and it would enter judgment in favor of Kerr-McGee.
    -23-
    In its brief on appeal and in post-summary judgment proceedings before
    the district court, Gamble Simmons argues that even under the contractual
    interpretation outlined in the district court’s orders, Kerr-McGee still owes
    money for services Gamble Simmons rendered. In support of its contention,
    Gamble Simmons submits an affidavit including calculations showing that, even
    excluding statutory interest refunded to Kerr-McGee and any benefit to Kerr-
    McGee from the application of the refund to later audits as instructed by the
    district court, Gamble Simmons still produced a benefit to Kerr-McGee in tax,
    penalty and interest refunds and reductions totaling $1,750,446.75. After taking
    forty percent of that amount ($700,178.70) and subtracting what Kerr-McGee has
    already paid ($665,418.10), Gamble Simmons claims Kerr-McGee still owes it
    the difference of $34,760.60 plus prejudgment interest.
    In reply to Gamble Simmons’ arguments, Kerr-McGee claims it has paid
    Gamble Simmons everything it owes, and explains the relatively small monetary
    difference between the amount it paid and the amount Gamble Simmons requests
    as attributable to certain “post-agreement payments” it made to the state of
    Louisiana. Kerr-McGee claims it made these payments to satisfy tax liabilities
    arising from Department audits encompassing the years 1985-1987, and that the
    Department later refunded the payments after it determined Kerr-McGee had
    -24-
    overpaid its tax liabilities for 1982-1984. Kerr-McGee argues that because it
    made the payments after contracting with Gamble Simmons, it need not include
    these amounts in its compensation calculations. In support of this claim, Kerr-
    McGee cites the terms of the contract which limit Gamble Simmons contingent
    interest to forty percent of any refund or reduction of amounts paid or assessed         as
    of the date of the agreement .
    B.     Discussion
    We agree with Kerr-McGee to the extent that the contract unambiguously
    limits Gamble Simmons’ compensation to payments or assessments made prior to
    the execution of the agreement. The contract specifically requires Kerr-McGee to
    pay Gamble Simmons forty percent of any reduction or refund in “total amounts
    of taxes, penalties and/or interest calculated      through the date of this Agreement   .”
    (Emphasis added). In other words, Gamble Simmons has no viable claim under
    the strict contractual language to any refund of payments Kerr-McGee made, if
    any, subsequent to the agreement date. The contract is clear on this point, and its
    interpretation is properly the subject of summary adjudication. Nevertheless, we
    find the court’s order problematic because it does not specifically address the
    issue of the alleged post-agreement payments, or sufficiently explain its rationale
    for determining that Kerr-McGee only owes Gamble Simmons what it had
    -25-
    previously paid.
    In our estimation, the district court overlooked a valid, additional issue
    raised by Gamble Simmons at this stage in the proceedings, specifically Kerr-
    McGee’s alleged post-agreement payments. We find no evidence of such
    payments in Kerr-McGee’s brief on appeal or in the proceedings below. In its
    brief, Kerr-McGee makes a general citation to the affidavit of its Assistant Tax
    Director for Research and Audits to support its claim. However, Kerr-McGee
    never explains how or where the affidavit shows any evidence of post-agreement
    payments, nor does our independent study of the affidavit reveal any support for
    Kerr-McGee’s post-agreement payment claim.     5
    Consequently, we must reverse the district court to the extent its decision
    rests upon Kerr-McGee’s unsubstantiated assertions of post-agreement payments.
    We remand for further proceedings with regard to the discrete issue of the post-
    5
    Perhaps somewhere buried in the record there is some support for Kerr-
    McGee’s position, but our review found no evidence either in the affidavit or
    other portions of the record. In the absence of sufficient citation to record
    support for a party’s allegations, we decline to search for the proverbial needle in
    a haystack. See Gross v. Burggraf Constr. Co., 
    53 F.3d 1531
    , 1546 (10th Cir.
    1995). If we have overlooked some crucial evidence, the parties will no doubt
    expose it on remand.
    -26-
    agreement payments and their effect on the ultimate calculation of Gamble
    Simmons’ compensation. On remand, the district court should afford the parties
    the opportunity to present evidence on the issue of the disputed post-agreement
    payments and provide a final, accurate calculation of Gamble Simmons’
    compensation based on our rulings in this case. As the case now stands on the
    record before us, we find no evidence to support the court’s summary judgment
    relating to the discrete issue of post-agreement payments and the effect, if any,
    on the amount owed to Gamble Simmons for its services under the contract.
    V. Attorneys’ Fees
    As part of this consolidated appeal, we also consider Gamble Simmons’
    challenge to the district court’s award of attorneys’ fees and costs to Kerr-
    McGee. In its first claim of error, Gamble Simmons asserts the district court
    should have stayed the determination of costs and attorneys’ fees pending our
    review of the underlying contract issues. Second, Gamble Simmons argues the
    district court committed error by failing to make findings of fact and conclusions
    of law regarding the award of attorneys’ fees and refusing to grant an evidentiary
    hearing on the reasonableness of the attorneys’ fees. Finally, Gamble Simmons
    claims the district court’s ultimate award of attorneys’ fees to Kerr-McGee was
    unreasonable.
    -27-
    Oklahoma law provides "[i]n any civil action to recover on ... [a] contract
    relating to ... labor or services, ... the prevailing party shall be allowed a
    reasonable attorney fee to be set by the court, to be taxed and collected as costs."
    
    Okla. Stat. tit. 12, § 936
    . The award of attorneys’ fees to the prevailing party
    under this provision is mandatory.    Arkla Energy Resources v. Roye Realty and
    Developing, Inc ., 
    9 F.3d 855
    , 865 (10th Cir.1993) (citing    Ellis v. Lebowitz , 
    799 P.2d 620
    , 621 (Okla. 1990)). However, the determination of reasonableness and
    amount of the fee award is generally left to the sound discretion of the district
    court. Harris Mkt. Research v. Marshall Mktg. & Communitcations, Inc.            , 
    948 F.2d 1518
    , 1527 (10th Cir. 1991) (applying an abuse of discretion standard and
    noting “an appellate court plays a ‘limited role’ in reviewing a district court’s
    award of attorneys’ fees and costs, and deference is given to a district court’s
    judgment on the matter, since the court is in a better position to assess the course
    of litigation and quality of work.” (Internal quotation marks & citation omitted)).
    Often, a hearing may be necessary to resolve material factual disputes between
    the parties over the reasonableness and amount of attorneys’ fees,     see Michael A.
    Cramer, MAI, SRPA, Inc. v. United States     , 
    47 F.3d 379
    , 383 (10th Cir. 1995)
    (finding “an evidentiary hearing is generally preferred, if not required, when
    factual diputes exist in connection with a request for attorneys fees”), unless the
    district court determines it has sufficient knowledge to make a decision without a
    -28-
    hearing based on its experience with the case, and briefs and affidavits submitted
    by the parties 
    id. at 383-84
    ; Harris Mkt. Research , 948 F.2d at 1528 (affirming
    grant, without evidentiary hearing, of prevailing party's request for attorneys' fees
    pursuant to contract where "[n]o hearing was necessary to aid the trial court's
    determination"). In any event, the district court should consider: (1) what
    attorney services were performed; (2) which services were necessary; (3) the
    value of the necessary services; and (4) what a reasonable fee for the services
    would be. Darrow v. Spencer , 
    581 P.2d 1309
    , 1314 (Okla. 1978). The court
    should then make an adequate record of its findings in the event appellate review
    is required. See King v. McCord , 
    621 F.2d 205
    , 207 (5th Cir. 1980) (holding
    district court’s ruling on attorneys’ fees without proper explication of its
    rationale renders appellate review of the award a “meaningless gesture”).
    Although these principles establish the bases for our review of an
    attorneys’ fees award, we decline to address any of the procedural and
    substantive issues raised by Gamble Simmons at this point. Although the parties’
    dispute over attorneys’ fees would have been ready for our review had we
    affirmed the district court’s judgment in all respects, because our decision to
    reverse in part and remand for further proceedings may require the district court
    to alter or amend its final judgment, we feel a decision on the merits of the
    -29-
    attorneys’ fees claim would be premature. If, for example, the district court
    ultimately determines Kerr-McGee still owes Gamble Simmons some degree of
    compensation, the court may alter its decision regarding the amount of attorneys’
    fees to award or perhaps even change who qualifies as the “prevailing party”
    under Okla Stat. tit. 12, § 936. Accordingly, due to the unsettled nature of the
    underlying judgment, we refrain from rendering an opinion on the attorneys’ fees
    issues raised by Gamble Simmons. We leave the attorneys’ fees issue open for
    unfettered reconsideration by the district court at the conclusion of these
    proceedings on remand.
    VI. Conclusion
    In summary, upon de novo review of these proceedings, we find the
    contract between Gamble Simmons and Kerr-McGee is unambiguous and any
    extrinsic evidence tending to alter the reasonable interpretation of the agreement
    is inadmissible. The contract clearly indicates Gamble Simmons should receive
    forty percent of the amount by which its efforts caused the Department to refund
    or reduce Kerr-McGee’s taxes, penalties and/or interest previously paid or
    assessed for 1982-1984. Accordingly, Gamble Simmons’ contingent fee should
    not include statutory interest included as part of the Department’s refund paid to
    Kerr-McGee, additional benefits realized by Kerr-McGee from the application of
    -30-
    a portion of the refund to tax liabilities for later years, or post-agreement
    payments, if any, later refunded to Kerr-McGee. Also, we find the contract does
    not permit Gamble Simmons to review Kerr-McGee books and records for later
    years, other than incident to Gamble Simmons’ review of the 1982-1984 audit.
    Therefore, we affirm the decision of the district court to the extent its summary
    judgment rulings reflect these conclusions. However, we reverse in part and
    remand for the district court to consider whether Kerr-McGee’s claimed post-
    agreement payments find sufficient evidentiary support to merit summary
    adjudication. Finally, in light of our decision, we decline to address the issues
    pertaining to the district court’s award of attorneys’ fees pending the outcome of
    the proceedings on remand.
    We AFFIRM in part, REVERSE in part and REMAND for further
    proceedings consistent with this opinion.

    This appeal involves the interpretation of a contract between Appellant,
    Gamble, Simmons and Company (“Gamble Simmons”) and Appellee, Kerr-
    McGee Corporation (“Kerr-McGee”), for tax consulting services. Gamble
    Simmons claims Kerr-McGee undercompensated the company for an audit review
    it performed and now brings this consolidated appeal challenging the district
    court’s grant of summary judgment and an award of attorneys’ fees in favor Kerr-
    McGee. We exercise jurisdiction pursuant to

    , and affirm in
    part, reverse in part, and remand.
    I. Introduction
    Gamble Simmons is a tax consulting firm specializing in the review and
    evaluation of audits by state taxing authorities. In September 1988, shortly after
    the Louisiana Department of Revenue and Taxation (“the Department”) issued
    Kerr-McGee a “Notice of Tax Due,” including tax, interest and penalties based
    on Sales and Use tax assessments for the years 1982-1984, Gamble Simmons
    approached Kerr-McGee with an offer to review the company’s records and
    determine whether it properly owed the taxes assessed, and whether the amount
    of tax could be reduced. Concerned about its tax liability, Kerr-McGee accepted
    -2-
    Gamble Simmons’ offer; and, in May 1991, the parties entered a contract
    (hereinafter “contract” or “agreement”) under which Gamble Simmons agreed to
    perform its tax consulting services for Kerr-McGee. The payment provisions of
    the agreement specifically obligate Kerr-McGee to pay Gamble Simmons “an
    amount equal to forty percent (40%) of the amount, if any, by which the total
    amounts of taxes, penalties and/or interest ... heretofore paid by Kerr-McGee ...
    and/or assessed by the Department ... are refunded or reduced.”
    Gamble Simmons performed under the agreement for the next three years,
    ultimately obtaining a very favorable outcome for Kerr-McGee. As a result of
    Gamble Simmons’ efforts, the Department admitted Kerr-McGee owed no
    additional taxes or interest for the years 1982-1984 and that it had actually
    overpaid taxes in the amount of $1,447,985. The Department subsequently
    refunded a portion of that amount directly to Kerr-McGee and applied the
    balance to offset taxes and interest Kerr-McGee owed for 1985-1987.
    After obtaining the favorable result, Gamble Simmons billed Kerr-McGee
    $1,095,439 for its services. However, Kerr-McGee disputed the charges and paid
    Gamble Simmons only $665,418, a figure Kerr-McGee arrived at through its own
    independent calculations. The difference between the parties’ figures resulted
    -3-
    from their conflicting interpretations of certain contract provisions and
    disagreement over what amounts to include in determining the contingency fee
    owed to Gamble Simmons. After settlement efforts failed, Gamble Simmons
    filed suit in the district court of Harris County, Texas to recover the difference in
    the amount claimed and the amount Kerr-McGee actually paid. Kerr-McGee
    subsequently removed the diversity action to federal court in the Western District
    of Oklahoma.
    Gamble Simmons’ final amended complaint stated several alternative
    causes of action. First, Gamble Simmons argued that by choosing to take a
    refund of tax and interest generated by its efforts rather than applying the credit
    to subsequent years’ tax liability – which would have resulted in reduced penalty
    and interest liability for those years – Kerr-McGee deprived Gamble Simmons of
    its forty percent fee on the savings. Second, Gamble Simmons alleged, as an
    alternative to its first cause of action, that Kerr-McGee received total benefits
    from Gamble Simmons’ efforts in the amount of $2,738,597.53 in tax, interest,
    and penalty reductions and refunds, and that the contract entitles Gamble
    Simmons to forty percent of those benefits. Specifically, Gamble Simmons
    claimed its compensation should include statutory interest paid to Kerr-McGee by
    the Department as part of the refund for overpayment. In its third cause of
    -4-
    action, Gamble Simmons asserted, in the alternative, that because Kerr-McGee
    representatives admitted the contract entitles Gamble Simmons to its percentage
    share of interest included as part of the refund, and some of Kerr-McGee’s own
    calculations indicate it owed Gamble Simmons $982,156.70, Kerr-McGee must
    pay Gamble Simmons the balance due of $316,738.60 plus pre-judgment interest.
    Fourth, as an alternative to its third cause of action, Gamble Simmons asserted
    that based on the actual refund Kerr-McGee received from the Department of
    $1,274,732.10, the correct amount payable to Gamble Simmons based on Kerr-
    McGee’s own calculation methods was $1,016,917.29, leaving an unpaid balance
    of $351,499.19 plus pre-judgment interest. Fifth, Gamble Simmons argued that
    even if the court found the contract did not permit it to share in interest Kerr-
    McGee received as part of the refund from the Department, the agreement at least
    entitles Gamble Simmons to its fee on the benefits conferred minus the interest.
    Gamble Simmons asserted this alternative amount was $787,498.94, and
    requested relief in the amount of the deficiency, $122,080.84, plus pre-judgment
    interest. Finally, in its sixth cause of action, Gamble Simmons contended Kerr-
    McGee breached the contract by refusing to allow Gamble Simmons to review
    Kerr-McGee’s books for periods beyond 1982-1984, and as a result, Gamble
    Simmons suffered the loss of fees it could have generated through reviewing later
    years’ records.
    -5-
    In September 1995, both parties filed simultaneous cross-motions for
    summary judgment to resolve Gamble Simmons’ claims. The district court issued
    an order on June 20, 1996 in which it addressed the parties’ motions and granted
    summary judgment in favor of Gamble Simmons in the amount of $769,850 less
    payments already made by Kerr-McGee. In reaching this conclusion, the district
    court decided the contract is not ambiguous and does not entitle Gamble
    Simmons to a portion of the interest paid to Kerr-McGee as part of the refund for
    overpayment. However, this initial interlocutory order did not dispose of all the
    issues in the case, and the parties subsequently filed additional cross-motions for
    summary judgment pertaining to the remaining issues.
    On June 4, 1997, the district court issued a comprehensive Memorandum
    Opinion and Order covering the remaining claims. The court decided the
    contract entitles Gamble Simmons to forty percent of the 1982-1984 refund
    generated through its efforts; but, the agreement does not allow Gamble Simmons
    to collect forty percent of the incidental interest and penalty reductions in
    subsequent years resulting from the application of 1982-1984 tax refund to the
    later periods. The district court based its decision primarily on the fact that the
    incidental interest or penalty savings Kerr-McGee realized on the 1985-1987
    audit were not based directly on Gamble Simmons’ work product or information.

    Additionally, the district court ruled the contract between the parties only
    contemplated a single audit involving the examination of Kerr-McGee’s 1982-
    1984 records. The court refused to grant Gamble Simmons’ request to review
    Kerr-McGee’s 1985-1991 records for any other purposes.     1
    After the court’s summary judgment rulings, the parties were unable to
    reach an accord on a proposed judgment as ordered by the court. Consequently,
    on October 27, 1997, the district court issued its own final judgment granting
    Kerr-McGee’s motion for summary judgment and awarding Gamble Simmons
    $665,418 for its services – the exact amount Kerr-McGee had already paid.
    On appeal, Gamble Simmons raises several issues. First, it contends the
    district court erred in finding Gamble Simmons was not entitled to a percentage
    of the interest the Department paid to Kerr-McGee as part of a refund for
    overpayment of taxes. Second, Gamble Simmons claims the district court should
    have considered extrinsic evidence it submitted regarding the formation of the
    agreement, the parties’ subjective interpretations of the agreement, and certain

    years’ records but only for purposes related to the 1982-1984 audit of Sales and
    Use taxes.
    -7-
    alleged admissions made by Kerr-McGee representatives regarding amounts owed
    to Gamble Simmons. Third, Gamble Simmons argues the district court erred
    when it decided the agreement only covered the audit of tax years 1982-1984.
    Fourth, Gamble Simmons claims the district court should have granted its Motion
    to Settle Contents, entered final judgment in its favor, and granted its motion for
    an evidentiary hearing on the contract interpretation issues. Finally, in a
    consolidated appeal, Gamble Simmons disputes the district court’s award of
    attorneys’ fees to Kerr-McGee.
    II. Standard of Review
    Because this appeal is based solely on the district court’s summary
    judgment rulings, we review the case   de novo , employing the same legal
    principles as the district court and construing the factual record and the
    reasonable inferences therefrom in the light most favorable to the party opposing
    summary judgment.    See Byers v. Albuquerque     
    150 F.3d 1271
    , 1274 (10th Cir.
    1998); Kane v. Capital Guardian Trust Co.      , 
    145 F.3d 1218
    , 1221 (10th Cir.
    1998). Summary judgment is appropriate if the record shows “there is no
    genuine issue as to any material fact and that the moving party is entitled to a
    judgment as a matter of law.” Fed. R. Civ. P. 56(c). An issue of material fact is
    genuine only if the nonmovant presents facts sufficient to show that a reasonable
    -8-
    jury could find in favor of the nonmovant.         Anderson v. Liberty Lobby, Inc.   , 
    477 U.S. 242
    , 248 (1986); see also Lawmaster v. Ward , 
    125 F.3d 1341
    , 1346-47
    (10th Cir. 1997). If our inquiry reveals no genuine issue of material fact in
    dispute, then we review the case to determine if the district court correctly
    applied the substantive law.   Kaul v. Stephan , 
    83 F.3d 1208
    , 1212 (10th Cir.
    1996).
    III. Contract Claims
    The present case requires us to ascertain the intent of the parties as
    expressed under the terms of their agreement with regard to Gamble Simmons’
    compensation. We must decide what portion of the tax reduction and refunds
    attributable to Gamble Simmons’ efforts are properly included as elements of its
    contingency fee under the agreement and what tax years the agreement
    encompasses.
    As a preliminary matter, we emphasize the law of the forum where the
    contract is made or is to be performed generally governs contract actions of this
    sort. Bohannan v. Allstate Ins. Co. , 
    820 P.2d 787
    , 793 (Okla. 1991);         see also
    
    Okla. Stat. tit. 15, § 162
    . In this diversity action the parties agree, and we find,
    the law of Oklahoma controls our inquiry.
    -9-
    In Oklahoma, a comprehensive statutory scheme governs contractual
    agreements. See 
    Okla. Stat. tit. 15, §§ 151
     - 178. These statutes provide that
    whenever possible we must give effect to mutual intent of the parties as
    expressed in the language of the contract, so long as it is unambiguous on its face
    and there exists no “fraud, accident, or pure absurdity” affecting the agreement.
    Public Serv. Co. of Okla. v. Burlington Northern R.R. Co.   , 
    53 F.3d 1090
    , 1097
    (10th Cir. 1995); 
    Okla. Stat. tit. 15, § 154
    . If the contract is ambiguous, then we
    may resort to extrinsic evidence, including the subsequent statements and actions
    of the parties, in order to construe the agreement.   See Pierce Couch Hendrickson
    Baysinger & Green v. Freede , 
    936 P.2d 906
    , 912 (Okla. 1997). However, if the
    contract is unambiguous its language is the only legitimate evidence of what the
    parties intended, see Mercury Inv. Co. v. F.W. Woolworth Co.    , 706 P.2d, 523m
    529 (Okla. 1985), and we will not rely on extrinsic evidence to vary or alter the
    plain meaning. See, e.g., Empire Oil & Ref. Co. v. Babson    , 
    77 P.2d 682
    , 684
    (Okla. 1938) (ruling that resort to extraneous evidence is proper only if the
    contract is ambiguous.)
    A.     The Question of Ambiguity
    Because Gamble Simmons seeks to prove the parties’ intent by utilizing
    extrinsic evidence, we must determine the admissibility of such evidence by first
    -10-
    deciding as a matter of law whether the terms of the contract between Kerr-
    McGee and Gamble Simmons are ambiguous.           Kerr-McGee Corp. v. Admiral Ins.
    Co., 
    905 P.2d 760
    , 762 (Okla. 1995). Oklahoma law states “[a] contract is
    ambiguous if reasonably susceptible of more than one interpretation.”     Williams
    v. Shearson Lehman Bros., Inc ., 
    917 P.2d 998
    , 1004 (Okla. Ct. App. 1996), or
    “through vagueness of expression it has a double meaning.”       See Cinocca v.
    Baxter Labs., Inc. , 
    400 F. Supp. 527
    , 532 (E.D. Okla. 1975). In other words, a
    contract is ambiguous if reasonably intelligent persons, on reading the contract,
    would honestly differ as to its proper meaning.    See United States Fidelity &
    Guar. Co. v. Guenther , 
    281 U.S. 34
    , 37 (1930).
    In this case, we acknowledge the parties’ basic disagreement over the
    interpretation of several provisions of the contract. However, the mere fact that
    the parties disagree about the meaning of a contract or argue for a different
    construction does not necessarily make the agreement ambiguous. A party cannot
    manufacture an ambiguity in a contract that is clear on its face merely by filing a
    lawsuit contesting its meaning or claiming an alternative interpretation.
    Moreover, if a contract is plain and unambiguous, it does not become ambiguous
    because its operation will work a hardship upon one of the parties and a
    corresponding advantage to the other. The dispositive factor in our analysis is
    -11-
    not whether the parties disagree or inequity results, but whether an examination
    of the entire agreement reveals more than one reasonable interpretation.
    Bartmann v. Maverick Tube Corp ., 
    853 F.2d 1540
    , 1545 (10th Cir. 1988)
    (finding “[a] term is unambiguous where it is reasonably and fairly susceptible of
    only one meaning”).
    In order to decide whether the contract is ambiguous, we look at the whole
    contract and construe the words as they are “understood in their ordinary and
    popular sense, rather than according to their strict legal meaning, unless used by
    the parties in a technical sense, or unless a special meaning is given to them by
    usage.” 
    Okla. Stat. tit. 15, §160
    . In the present case, the parties’ intent is
    apparent, regardless of whether the terms are read in their ordinary, legal, or
    technical sense. The compensation clause at the heart of this contract dispute
    plainly and succinctly enumerates the elements of tax savings properly included
    in calculating Gamble Simmons’ contingency fee, as well as the tax years for
    which Gamble Simmons is permitted to perform its services. Although Gamble
    Simmons urges us to find the terms ambiguous and thereby allow the introduction
    of extrinsic evidence tending to contradict the express contract language, we
    decline to indulge its strained construction of the agreement to “create and then
    construe an ambiguity so as to import a favorable consideration to either party
    -12-
    than that expressed in the contract.”    Kerr-McGee, 905 P.2d at 763 (internal
    quotation marks & citation omitted);     see also Max True Plastering Co. v. United
    States Fidelity & Guar. Co. , 
    912 P.2d 861
    , 869 (Okla. 1996) (refusing to indulge
    in constrained interpretations of contracts to find ambiguity). Our review of the
    record reveals contract terms that are unambiguous, readily understood, and not
    “fairly susceptible” of various interpretations. Therefore, in the absence of any
    “fraud, deception, or unfair dealing” by either party in procuring the agreement,
    or “legal impediment shown” that prevented the parties from entering into the
    contract and expressing it in language of their own choosing, we will not resort
    to extrinsic evidence to interpret or revise the agreement.   Northwestern Oil &
    Gas Co. v. Branine , 
    175 P. 533
    , 534 (Okla. 1918).      2
    B.     Applying the Terms of the Contract
    Having decided the contract is unambiguous and a clear reflection of the
    parties’ intentions, we now apply the terms of the contract to resolve the
    2
    Because we find the terms pertaining to contested issues in this lawsuit
    unambiguous, we ignore Gamble Simmons’ proposed evidence of telephone
    conversations with Kerr-McGee representatives and any other extrinsic evidence
    tending to disturb or alter the plain meaning of the contract terms. See
    Prudential Ins. Co. v. Glass, 
    959 P.2d 586
    , 594 (Okla. 1998) (ruling that if a
    contract is complete in itself and is unambiguous when viewed in its entirety, "its
    language is the only legitimate evidence of what the parties intended").
    -13-
    contested contractual issues in this case. The agreement plainly reveals the
    parties’ intent with regard to both the amounts to include in calculating Gamble
    Simmons’ contingency fee and the permissible scope of its right to review Kerr-
    McGee’s records.
    1.    Refund Amounts Properly Included the Contingent Fee
    In terms of compensation, the contract states that Gamble Simmons should
    receive
    an amount equal to forty percent (40%) of the amount, if any, by
    which the total amounts of taxes, penalties and/or interest calculated
    through the date of this Agreement heretofore paid by Kerr-McGee
    to its vendors, the State of Louisiana and/or assessed by the
    Department but remain unpaid as of the date hereof, are refunded or
    reduced ....
    (Emphasis added). Interpreting this clause, the district court correctly decided
    the agreement entitles Gamble Simmons to no more compensation for its services
    than forty percent of any refund or reduction in taxes previously paid or assessed
    as part of the 1982-1984 audit. In other words, the statutory interest the
    Department included as part of the refund to Kerr-McGee is not an amount
    subject to Gamble Simmons’ contingency fee under the contract because it does
    not reflect an amount paid by Kerr-McGee or assessed against it for the years
    1982-1984. The statutory interest actually represents a reasonable return on the
    amount the Department erroneously charged Kerr-McGee in prior years.
    -14-
    Nowhere does the contract contemplate Gamble Simmons sharing in this statutory
    interest either expressly or impliedly. We note, however, the contract provides
    Gamble Simmons should receive forty percent of the refund or reduction based
    on the total amount of 1982-1984 taxes overpaid or assessed in 1982-1984,
    regardless of whether the overpayment is actually repaid directly to Kerr-McGee
    or applied to later years’ tax liability – as long as those amounts are based on
    Gamble Simmons’ efforts during the its review of the 1982-1984 audit.
    We find Gamble Simmons’ counter-arguments on this point unavailing.
    Our interpretation of the contract does not, as Gamble Simmons contends, render
    the term “refund” in the contract a nullity. Rather, it reflects the intent of the
    parties as clearly expressed in the terms of the contract by giving effect to the
    meaning of “refund” as used in conjunction with other language in the contract to
    limit Gamble Simmons’ contingency fee to refund amounts “heretofore paid” by
    Kerr-McGee or “assessed” by the Department. Moreover, our reading of the
    contract does not have the effect of eliminating the reduction of assessed interest
    as part of Gamble Simmons’ contingent compensation. On the contrary, we
    recognize the contract clearly requires Kerr-McGee to pay Gamble Simmons its
    contingent share of reductions in interest assessed against Kerr-McGee for the
    1982-1984 audit period. The “interest” not subject to Gamble Simmons’
    -15-
    contingent fee is the statutory interest awarded to Kerr-McGee as part of the
    refund for overpayment.
    We are similarly unpersuaded by Gamble Simmons’ argument asserting
    that because Louisiana Rev. Stat. Ann. § 47:1624(A) mandates the payment of
    interest as part of a Department refund for tax overpayments, the statute must be
    read into Gamble Simmons’ contract with Kerr-McGee to make the term “refund”
    include the statutory interest. Gamble Simmons’ argument on this point refers to
    a sound legal principle of contract construction which states “      unless the contract
    discloses a contrary intention     , an existing statute will be read into it to the same
    effect as an express provision.”      United States v. Essley,   
    284 F.2d 518
    , 520 (10th
    Cir. 1960) (emphasis added). Nevertheless, we question the applicability of this
    principle in the present case because the contract expresses an intention contrary
    to the statute. Again, we emphasize the terms of the contract expressly limit
    Gamble Simmons’ contingent share to amounts “heretofore paid” or “assessed”
    that are “refunded or reduced.” In light of this limiting language in the contract
    that discloses an intention not to include the statutory interest as part of the
    refund, we decline to interpret the term refund as used in the contract to
    incorporate Louisiana Rev. Stat. Ann. § 47:1624(A).
    -16-
    All other arguments aside, the basic problem with Gamble Simmons’
    position is that it urges us to imply contract provisions that simply are not there.
    For example, in its brief Gamble Simmons states that “paragraph 4 of the
    Agreement clearly contemplates that to the extent Kerr-McGee      received any
    benefit in reduction of taxes, interest and penalties, Gamble Simmons’ fee would
    be 40% thereof.” (Emphasis added). However, Gamble Simmons’ statement
    does not reflect the agreement of the parties as expressed in the unambiguous
    terms of the contract. The agreement between the parties is not to pay Gamble
    Simmons a portion of any   benefit Kerr-McGee received through Gamble
    Simmons’ efforts, but a contingent interest in the amount by which Gamble
    Simmons’ services resulted in the refund or reduction of taxes, interest, and/or
    penalties previously paid by Kerr-McGee or assessed by the Department during
    the audit period. The contract enumerates a specific range of compensable
    interests, not the wide-open “benefit” approach Gamble Simmons advocates.
    2.     Application of the Refund to Subsequent Years’ Tax Liability
    We also agree with the district court’s assessment with regard to the
    application of the contract to later years’ taxes. Gamble Simmons is only entitled
    to its contingent share of the refund or reduction in amounts previously paid or
    assessed for tax years 1982-1984, whether such amounts are actually paid directly
    -17-
    to Kerr-McGee or applied to later years’ taxes.
    In addition to its share of the 1982-1984 refund amounts applied to Kerr-
    McGee’s 1985-1987 tax liability, Gamble Simmons also claims Kerr-McGee
    owes it forty percent of the interest reductions Kerr-McGee realized in the 1985-
    1987 audit period through application of the 1982-1984 refund. However,
    Gamble Simmons’ claim again contravenes the language of the contract. Our
    reading of the agreement persuades us that Gamble Simmons is entitled to
    compensation only for whatever amount its efforts       directly caused the
    Department to refund or reduce taxes, interest and penalties previously paid by or
    assessed against Kerr-McGee with regard to the 1982-1984 audit. The indirect,
    incidental benefit of interest reduction that occurred as a result of the
    Department’s unilateral application of a portion of the 1982-1984 refund to Kerr-
    McGee’s later years’ tax liability is not subject to Gamble Simmons’ forty
    percent contingent fee because the interest reduction is not the    direct result of
    Gamble Simmons efforts with regard to its 1982-1984 audit review. In other
    words, the incidental benefit to Kerr-McGee for the interest reduction in 1985-
    1987 represents the consequence of the Department’s decision to apply the 1982-
    1984 refund to subsequent audits –     not the result of Gamble Simmons’ efforts.
    -18-
    This result makes sense if we hypothesize for a moment about what amount
    Gamble Simmons would have received if the Department had refunded the entire
    sum directly to Kerr-McGee and not applied any amount toward subsequent tax
    liabilities. Under those circumstances, Gamble Simmons would still receive its
    forty percent share of the refunded amount as provided by the contract, but it
    would have no further claim for compensation from any incidental or secondary
    financial benefit Kerr-McGee might enjoy through the productive use of the
    refund. For example, if Kerr-McGee took the refund and immediately paid off an
    outstanding debt, Gamble Simmons clearly would not have a viable claim for a
    share of the interest savings Kerr-McGee would realize from the transaction.
    Likewise, if Kerr-McGee took the refund and immediately paid its tax liability
    for the 1985-1987 audit, Gamble Simmons would have no claim to the
    accompanying reduction in interest on the tax liability. We see no difference of
    any significance between these hypothetical examples and what actually
    happened in the present case. The Department’s unilateral decision to apply a
    portion of the 1982-1984 refund to the later audit has the same effect as if Kerr-
    McGee itself had received the refund and immediately paid its 1985-1987 tax
    liability.
    If the contract had stated the parties’ intention for Gamble Simmons to not
    -19-
    only share in the reduction or refund of taxes, penalties or interest Kerr-McGee
    realized from Gamble Simmons efforts with regard to the 1982-1984 audit,        but
    also whatever incidental reduction resulted from the application of the 1982-1984
    refund to later years’ tax liability, then Gamble Simmons would have a viable
    claim for its share of the incidental benefit. However, understood in its entirety,
    the contract simply does not evidence Gamble Simmons’ right to share in the
    secondary benefits realized by Kerr-McGee through the Department’s unilateral
    application of the 1982-1984 refund to the 1985-1987 audit. Therefore, we
    affirm the district court’s conclusion that refunds and reductions in taxes,
    penalties, and interest previously paid or assessed in 1982-1984 are subject to
    Gamble Simmons’ forty percent fee, but the incidental reductions in interest or
    penalties resulting from the application of the 1982-1984 refund are not.   3
    3
    Gamble Simmons makes a very puzzling argument in its brief contesting
    the district court’s finding on this issue we feel compelled to address. It asserts
    that if the district court’s conclusion regarding the interpretation of the contract is
    taken to its logical extreme, it would mean Gamble Simmons would receive no
    compensation if the entire refund it generated had been applied to subsequent
    years’ taxes, interest, and penalties. If this is Gamble Simmons’ understanding of
    the district court’s ruling, we believe it has misinterpreted the findings. Our
    decision to deny Gamble Simmons any compensation for benefits realized by
    Kerr-McGee from the application of a portion of the refund to subsequent years’
    taxes under the terms of the contract, in no way means Gamble Simmons would
    get nothing for its services if the refund was applied entirely to subsequent years.
    On the contrary, Gamble Simmons is entitled to everything the contract allows –
    forty percent of taxes, interest, and/or penalties previously paid or assessed during
    the 1982-1984 audit period which the Department refunded or reduced because of
    Gamble Simmons efforts. As long as the refund represents such amounts, Gamble
    -20-
    3.      Access to Later Years’ Records
    To the extent Gamble Simmons requests access Kerr-McGee’s records for
    later years’ taxes, we find the terms of the contract do not so provide. The
    agreement only allows
    Gamble Simmons to review Kerr-McGee’s books and records with
    respect to transactions involving Louisiana Sales and Use Taxes for
    the applicable statutory periods for the purpose of evaluating said
    audits and assessments and advising Kerr-McGee with respect
    thereto ....
    Although, viewed in isolation, this provision contains no express limitations on
    Gamble Simmons’ asserted right to audit Kerr-McGee’s records, we must
    interpret it in light of the entire contract.     See 
    Okla. Stat. Ann. tit. 15, § 157
    (1991) ("The whole of a contract is to be taken together, so as to give effect to
    every part, if reasonably practicable, each clause helping to interpret the
    others."). In addition to the clause noted, the contract also contains other
    provisions that lend context and perspective to our application. The opening
    recitals are especially helpful to objectively analyze the intent of the parties with
    regard to the scope of the audit. They discuss the Department’s audit of Kerr-
    Simmons is entitled to its share whether the refund is paid directly to Kerr-McGee
    or applied to subsequent years. What Gamble Simmons does not share in as part
    of its compensation, is the resulting incidental tax, penalty and/or interest
    reduction realized through application of the refund to later tax years because that
    reduction is not directly attributable to services Gamble Simmons performed in its
    review of the 1982-1984 audit.
    -21-
    McGee’s Sales and Use taxes paid in 1982-1984, and imply that the Department’s
    audit was the driving force behind Kerr-McGee’s decision to contract for Gamble
    Simmons’ services. Using these initial recitals as a backdrop, we find the only
    reasonable construction of the subsequent terms of the contract is that the parties
    intended to limit the scope of Gamble Simmons’ work to the 1982-1984 audit.
    When the contract refers specifically to “the applicable statutory periods”, we
    believe that clause plainly makes reference to the aforementioned 1982-1984
    audits discussed in the opening recitals of the contract, not “applicable statutory
    periods” in the some general sense. Accordingly, we find the agreement contains
    no compelling support for Gamble Simmons’ argument that it is entitled to
    examine Kerr-McGee’s records for additional statutory periods, other than where
    necessary as incidental to its audit for 1982-1984.   4
    4
    Moreover, even if we strained the language to find the contract allowed
    Gamble Simmons to review later tax years, in no way does the contract indicate
    the parties mutually agreed to have Gamble Simmons perform its services and
    receive compensation for tax years beyond the 1982-1984 period specifically
    discussed in the opening recitals of the contract.

    IV. Post-Summary Judgment Proceedings
    A.     Background
    Following the district court’s June 4, 1997 Memorandum & Order granting
    Kerr-McGee’s motion for summary judgment, the court instructed the parties to
    submit a proposed final judgment reflecting the court’s ruling. However,
    negotiations failed and the parties were unable to reach an accord regarding the
    content of the final judgment. The parties essentially disagreed about how to
    calculate Gamble Simmons’ final compensation, while giving effect to the district
    court’s interpretation of the contract. The major point of contention was whether
    to exclude from Gamble Simmons’ compensation certain refunds the Department
    made to Kerr-McGee of payments Kerr-McGee rendered after the execution of
    the agreement (hereinafter “post-agreement payments”). Because the parties
    could not agree, Gamble Simmons filed a motion to settle the contents of the
    final judgment and a request for an evidentiary hearing on the compensation
    calculation issue. After consideration of the parties’ arguments, the district court
    denied Gamble Simmons’ post-summary judgment motion to settle contents and
    request for an evidentiary hearing in an order dated October 27, 1997. In its
    order, the district court stated its summary judgment orders already resolved all
    the issues presented, and it would enter judgment in favor of Kerr-McGee.
    -23-
    In its brief on appeal and in post-summary judgment proceedings before
    the district court, Gamble Simmons argues that even under the contractual
    interpretation outlined in the district court’s orders, Kerr-McGee still owes
    money for services Gamble Simmons rendered. In support of its contention,
    Gamble Simmons submits an affidavit including calculations showing that, even
    excluding statutory interest refunded to Kerr-McGee and any benefit to Kerr-
    McGee from the application of the refund to later audits as instructed by the
    district court, Gamble Simmons still produced a benefit to Kerr-McGee in tax,
    penalty and interest refunds and reductions totaling $1,750,446.75. After taking
    forty percent of that amount ($700,178.70) and subtracting what Kerr-McGee has
    already paid ($665,418.10), Gamble Simmons claims Kerr-McGee still owes it
    the difference of $34,760.60 plus prejudgment interest.
    In reply to Gamble Simmons’ arguments, Kerr-McGee claims it has paid
    Gamble Simmons everything it owes, and explains the relatively small monetary
    difference between the amount it paid and the amount Gamble Simmons requests
    as attributable to certain “post-agreement payments” it made to the state of
    Louisiana. Kerr-McGee claims it made these payments to satisfy tax liabilities
    arising from Department audits encompassing the years 1985-1987, and that the
    Department later refunded the payments after it determined Kerr-McGee had
    -24-
    overpaid its tax liabilities for 1982-1984. Kerr-McGee argues that because it
    made the payments after contracting with Gamble Simmons, it need not include
    these amounts in its compensation calculations. In support of this claim, Kerr-
    McGee cites the terms of the contract which limit Gamble Simmons contingent
    interest to forty percent of any refund or reduction of amounts paid or assessed         as
    of the date of the agreement .
    B.     Discussion
    We agree with Kerr-McGee to the extent that the contract unambiguously
    limits Gamble Simmons’ compensation to payments or assessments made prior to
    the execution of the agreement. The contract specifically requires Kerr-McGee to
    pay Gamble Simmons forty percent of any reduction or refund in “total amounts
    of taxes, penalties and/or interest calculated      through the date of this Agreement   .”
    (Emphasis added). In other words, Gamble Simmons has no viable claim under
    the strict contractual language to any refund of payments Kerr-McGee made, if
    any, subsequent to the agreement date. The contract is clear on this point, and its
    interpretation is properly the subject of summary adjudication. Nevertheless, we
    find the court’s order problematic because it does not specifically address the
    issue of the alleged post-agreement payments, or sufficiently explain its rationale
    for determining that Kerr-McGee only owes Gamble Simmons what it had
    -25-
    previously paid.
    In our estimation, the district court simply ignored a valid, additional issue
    raised by Gamble Simmons at this stage in the proceedings, specifically Kerr-
    McGee’s alleged post-agreement payments. We find no evidence of such
    payments in Kerr-McGee’s brief on appeal or in the proceedings below. In its
    brief, Kerr-McGee makes a general citation to the affidavit of its Assistant Tax
    Director for Research and Audits to support its claim. However, Kerr-McGee
    never explains how or where the affidavit shows any evidence of post-agreement
    payments, nor does our independent study of the affidavit reveal any support for
    Kerr-McGee’s post-agreement payment claim.     5
    We are simultaneously baffled and disturbed by the district court’s sudden
    adoption of Kerr-McGee’s calculations as the basis of final judgment, especially
    since we find nothing in the record to substantiate Kerr-McGee’s claimed post-
    5
    Perhaps somewhere buried in the record there is some support for Kerr-
    McGee’s position, but our review found no evidence either in the affidavit or
    other portions of the record. In the absence of sufficient citation to record
    support for a party’s allegations, we decline to search for the proverbial needle in
    a haystack. See Gross v. Burggraf Constr. Co., 
    53 F.3d 1531
    , 1546 (10th Cir.
    1995). If we have overlooked some crucial evidence, the parties will no doubt
    expose it on remand.
    -26-
    agreement payments. Consequently, we must reverse the district court to the
    extent its decision rests upon Kerr-McGee’s unsubstantiated assertions of post-
    agreement payments. We remand for further proceedings with regard to the
    discrete issue of the post-agreement payments and their effect on the ultimate
    calculation of Gamble Simmons’ compensation. On remand, the district court
    should afford the parties the opportunity to present evidence on the issue of the
    disputed post-agreement payments and provide a final, accurate calculation of
    Gamble Simmons’ compensation based on our rulings in this case. As the case
    now stands on the record before us, we find no evidence to support the court’s
    summary judgment relating to the discrete issue of post-agreement payments and
    the effect, if any, on the amount owed to Gamble Simmons for its services under
    the contract.
    V. Attorneys’ Fees
    As part of this consolidated appeal, we also consider Gamble Simmons’
    challenge to the district court’s award of attorneys’ fees and costs to Kerr-
    McGee. In its first claim of error, Gamble Simmons asserts the district court
    should have stayed the determination of costs and attorneys’ fees pending our
    review of the underlying contract issues. Second, Gamble Simmons argues the
    district court committed error by failing to make findings of fact and conclusions
    -27-
    of law regarding the award of attorneys’ fees and refusing to grant an evidentiary
    hearing on the reasonableness of the attorneys’ fees. Finally, Gamble Simmons
    claims the district court’s ultimate award of attorneys’ fees to Kerr-McGee was
    unreasonable.
    Oklahoma law provides "[i]n any civil action to recover on ... [a] contract
    relating to ... labor or services, ... the prevailing party shall be allowed a
    reasonable attorney fee to be set by the court, to be taxed and collected as costs."
    
    Okla. Stat. tit. 12, § 936
    . The award of attorneys’ fees to the prevailing party
    under this provision is mandatory.    Arkla Energy Resources v. Roye Realty and
    Developing, Inc ., 
    9 F.3d 855
    , 865 (10th Cir.1993) (citing    Ellis v. Lebowitz , 
    799 P.2d 620
    , 621 (Okla. 1990)). However, the determination of reasonableness and
    amount of the fee award is generally left to the sound discretion of the district
    court. Harris Mkt. Research v. Marshall Mktg. & Communitcations, Inc.            , 
    948 F.2d 1518
    , 1527 (10th Cir. 1991) (applying an abuse of discretion standard and
    noting “an appellate court plays a ‘limited role’ in reviewing a district court’s
    award of attorneys’ fees and costs, and deference is given to a district court’s
    judgment on the matter, since the court is in a better position to assess the course
    of litigation and quality of work.” (Internal quotation marks & citation omitted)).
    Often, a hearing may be necessary to resolve material factual disputes between
    -28-
    the parties over the reasonableness and amount of attorneys’ fees,   see Michael A.
    Cramer, MAI, SRPA, Inc. v. United States     , 
    47 F.3d 379
    , 383 (10th Cir. 1995)
    (finding “an evidentiary hearing is generally preferred, if not required, when
    factual diputes exist in connection with a request for attorneys fees”), unless the
    district court determines it has sufficient knowledge to make a decision without a
    hearing based on its experience with the case, and briefs and affidavits submitted
    by the parties 
    id. at 383-84
    ; Harris Mkt. Research , 948 F.2d at 1528 (affirming
    grant, without evidentiary hearing, of prevailing party's request for attorneys' fees
    pursuant to contract where "[n]o hearing was necessary to aid the trial court's
    determination"). In any event, the district court should consider: (1) what
    attorney services were performed; (2) which services were necessary; (3) the
    value of the necessary services; and (4) what a reasonable fee for the services
    would be. Darrow v. Spencer , 
    581 P.2d 1309
    , 1314 (Okla. 1978). The court
    should then make an adequate record of its findings in the event appellate review
    is required. See King v. McCord , 
    621 F.2d 205
    , 207 (5th Cir. 1980) (holding
    district court’s ruling on attorneys’ fees without proper explication of its
    rationale renders appellate review of the award a “meaningless gesture”).
    Although these principles establish the bases for our review of an
    attorneys’ fees award, we decline to address any of the procedural and
    -29-
    substantive issues raised by Gamble Simmons at this point. Although the parties’
    dispute over attorneys’ fees would have been ready for our review had we
    affirmed the district court’s judgment in all respects, because our decision to
    reverse in part and remand for further proceedings may require the district court
    to alter or amend its final judgment, we feel a decision on the merits of the
    attorneys’ fees claim would be premature. If, for example, the district court
    ultimately determines Kerr-McGee still owes Gamble Simmons some degree of
    compensation, the court may alter its decision regarding the amount of attorneys’
    fees to award or perhaps even change who qualifies as the “prevailing party”
    under Okla Stat. tit. 12, § 936. Accordingly, due to the unsettled nature of the
    underlying judgment, we refrain from rendering an opinion on the attorneys’ fees
    issues raised by Gamble Simmons. We leave the attorneys’ fees issue open for
    unfettered reconsideration by the district court at the conclusion of these
    proceedings on remand.
    VI. Conclusion
    In summary, upon de novo review of these proceedings, we find the
    contract between Gamble Simmons and Kerr-McGee is unambiguous and any
    extrinsic evidence tending to alter the reasonable interpretation of the agreement
    is inadmissible. The contract clearly indicates Gamble Simmons should receive
    -30-
    forty percent of the amount by which its efforts caused the Department to refund
    or reduce Kerr-McGee’s taxes, penalties and/or interest previously paid or
    assessed for 1982-1984. Accordingly, Gamble Simmons’ contingent fee should
    not include statutory interest included as part of the Department’s refund paid to
    Kerr-McGee, additional benefits realized by Kerr-McGee from the application of
    a portion of the refund to tax liabilities for later years, or post-agreement
    payments, if any, later refunded to Kerr-McGee. Also, we find the contract does
    not permit Gamble Simmons to review Kerr-McGee books and records for later
    years, other than incident to Gamble Simmons’ review of the 1982-1984 audit.
    Therefore, we affirm the decision of the district court to the extent its summary
    judgment rulings reflect these conclusions. However, we reverse in part and
    remand for the district court to consider whether Kerr-McGee’s claimed post-
    agreement payments find sufficient evidentiary support to merit summary
    adjudication. Finally, in light of our decision, we decline to address the issues
    pertaining to the district court’s award of attorneys’ fees pending the outcome of
    the proceedings on remand.
    We AFFIRM in part, REVERSE in part and REMAND for further
    proceedings consistent with this opinion.
