    GRIFFIN, Circuit Judge.
    In this action, plaintiffs Eggert Agency Inc., Mount Carmel Health System, James R. Eggert,
    and Gregory R. Nickell filed suit against defendants Meritain Health, Inc., NA Management Corp.,
    and North American Benefits Network, Inc., asserting several claims relating to defendants’
    performance of obligations required under a share purchase agreement. Following a four-day bench
    trial, the district court found in favor of plaintiffs, awarding significant monetary damages, but
    declining to award prejudgment interest. Both parties filed timely appeals. Defendants appeal the
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    issue of damages, only. Plaintiffs cross-appeal the district court’s refusal to award prejudgment
    interest. Upon review, we affirm in part, reverse in part, and remand.
    I.
    In 2003, plaintiffs Eggert Agency, Inc. (“Eggert Agency”) and Mount Carmel Health System
    (“Mount Carmel”) sold E-V Benefits Management, Inc. (“E-V”), a central Ohio third-party
    administrator (“TPA”), to two affiliated corporations, defendants NA Management Corp. and North
    American Benefits Network, Inc. (collectively “NABN”). At that time, Eggert Agency and Mount
    Carmel were the only shareholders of E-V, while plaintiffs James R. Eggert and Gregory R. Nickell
    were E-V executive officers and employees.
    NABN’s acquisition of E-V was memorialized in a share purchase agreement (“SPA”) with
    a purchase price of $1,135,000. Twenty percent of this amount, $227,000, was paid immediately
    upon execution of the SPA. The remaining eighty percent of the purchase price was to be paid in
    the form of two seven-year subordinated term notes. However, the subordinated term notes were
    subject to an adjustment on the third anniversary of the acquisition’s closing. This adjustment was
    to be calculated as follows:
    If the average Revenue for the three year period following the Closing (the “Actual
    Revenue”) is less than the Base Revenue Amount, the shortfall shall be multiplied
    by the Revenue Multiple and then by the Stock Factor and the resulting amount shall
    be deducted from the principal amount outstanding and reamortized at the same
    interest rate over the remaining four years. If the average Revenue for the three year
    period following the Closing is greater than the Base Revenue Amount, the excess
    shall be multiplied by the Revenue Multiple and then by the Stock Factor and the
    resulting amount shall be added to the principal amount outstanding and reamortized
    over the ensuing four years. Interest on the adjusted Principal Amount shall accrue
    from the third anniversary of the Closing.

    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    Put more simply, the payments due during the final four years of the payment period were contingent
    upon the generation of revenue attributable to E-V during the first three years of the payment period
    (the “revenue period”). Payments to Eggert and Nickell were similarly dependent upon the revenue
    generated by E-V during this time, as provided by the E-V Benefits Management Inc. Incentive
    Growth Plan (the “growth plan”), which was incorporated into the SPA. To ensure that NABN
    would generate revenue attributable to E-V during the revenue period, the SPA provided certain
    obligations:
    NABN shall:
    a.      Introduce established marketing (i.e. broker/consultant) relationships in the
    Greater Columbus, Greater Toledo and other appropriate areas to the E-V
    Marketing personnel, as appropriate.
    b.      Train the E-V Marketing personnel and all other appropriate staff on all of
    NABN’s products and services.
    c.      Provide marketing materials.
    d.      Provide marketing support in the form of proposal generation, presentation
    assistance, etc., by NABN officers, directors or staff.
    e.      Retain an E-V marketing staff to be designated as the E-V Marketing
    Resource, reporting to NABN’s Executive Vice President, Marketing &
    Sales.
    f.      Provide for reasonable commission schedules for sales staff.
    These obligations later passed onto defendant Meritain Health, Inc. (“Meritain”), which acquired
    NABN on December 23, 2004.
    -3-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    Before the execution of the SPA, E-V was a prominent central Ohio TPA, retaining 65
    employees and averaging $4,000,000 in annual revenues. However, E-V did not perform well under
    the direction of defendants. At the end of the revenue period, the revenue generated by E-V was far
    lower than expected. Indeed, E-V lost the vast majority of its clients, beginning the revenue period
    with 22 clients, and ending with 2. In addition, E-V did not obtain any new clients during the
    revenue period. As a result of this poor performance, the adjustment that took place on the third
    anniversary of the acquisition’s closing resulted in significantly reduced payments to plaintiffs.
    Alleging that defendants failed to honor their obligations in generating revenue attributable
    to E-V, plaintiffs filed suit in Ohio state court on September 7, 2007. Defendants thereafter removed
    the matter to the United States District Court for the Southern District of Ohio based upon diversity
    jurisdiction. In their complaint, plaintiffs asserted several Ohio-law claims sounding in contract and
    tort. Following defendants’ motion to dismiss and motion for summary judgment, plaintiffs’ sole
    remaining claim for breach of contract proceeded to a four-day bench trial.
    On January 22, 2010, the district court entered findings of fact and conclusions of law
    favorable to plaintiffs. Therein, the district court concluded that defendants had breached the express
    requirements of the SPA by failing to introduce established marketing relationships to E-V personnel
    and failing to maintain E-V marketing staff. In addition, the district court found that defendants
    breached the duty to expend reasonable efforts and the implied covenant of good faith and fair
    dealing by failing to employ sufficient E-V marketing staff, closing E-V’s Columbus office,
    eliminating the E-V brand, and preventing E-V from obtaining Summit County, Ohio as a client.
    -4-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    The district court then proceeded to address the issue of damages. First, the district court
    found that, absent defendants’ breach of the SPA, E-V would have been able to capitalize on a
    promising local TPA market “exploding with opportunities.” Thereafter, the district court relied
    upon the expert testimony of Glenn McLellan to determine the monetary value of this lost business.
    Specifically, the district court found that, absent defendants’ breach, E-V was reasonably certain to
    have closed on 6% of 70 new business opportunities each year, resulting in 4 new clients per year.
    Multiplying these 4 clients by the average number of covered employees, 375, yielded a total of
    1,500 new covered employees per year. With each covered employee generating an average of $20
    in revenue per month, the district court held it was reasonably certain that E-V would have generated
    $30,000 in new business revenue per month, resulting in $360,000 each year. Finding that revenue
    generated from new clients would carry throughout the revenue period, the added revenue was found
    to be $360,000 for the first year, $720,000 for the second year, and $1,080,000 for the third year,
    yielding $2,160,000 for all three years and an average annual increase in revenue of $720,000.
    These lost profits were then added to the “base revenue amount,” defined by the SPA as
    $4,298,000. The district court determined, based upon the testimony of Eggert, that the base revenue
    amount represented the parties’ agreement as to the annual revenue E-V would have expected at the
    time of acquisition, assuming no loss or gain in clients. Also added to the base revenue amount was
    the value of a contract with Summit County, which the district court found that defendants had
    prevented E-V from obtaining.
    -5-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    The district court also analyzed the facts and circumstances, unrelated to defendants’ breach,
    which may have caused the loss of former and prospective clients. First, the district court credited
    the testimony of Todd Squilanti, a Meritain employee, who testified that upon acquisition, businesses
    generally “forecast a minimum of 15 percent attrition[.]” Accordingly, the court found that 15% of
    the base revenue amount, $644,700, represented annual losses caused by the acquisition and a
    required system conversion. In addition, the district court found that the loss of one E-V client, Max
    & Erma’s, was unrelated to defendants’ breach. Finally, the district court addressed other possible
    causes of client attrition, including the loss of a principal sales person and general staff reductions.
    However, the district court found that such issues did not affect E-V’s client retention.
    Based upon these calculations, the district court summarized its findings as follows:
    Having considered the parties’ agreed expectations regarding baseline revenue, the
    market opportunities described at trial, and the various challenges faced by E-V, the
    Court finds that, in the absence of a breach, E-V would have enjoyed an average
    annual Revenue of $4,514,100 during the Revenue Period. This amount is the sum
    of the Base Revenue Amount ($4,298,000) and the average annual increase E-V
    should have enjoyed from existing market opportunities in Columbus ($720,000) and
    the Summit County opportunity ($376,000), less the annual amounts lost due to
    factors unrelated to Defendant’s breach: the amount lost due to the acquisition and
    associated rocky system conversion process ($644,700) and the decrease in revenue
    from the loss of Max & Erma’s ($235,200).
    The district court then placed its projected annual revenue amount into the adjustment calculation
    provided by the SPA to determine the proper payments to plaintiffs under the subordinated term
    notes and the growth plan. However, the district court declined to award prejudgment interest. Both
    parties filed timely appeals.

    Eggert, et al. v. Meritain Health, Inc., et al.
    II.
    On appeal, defendants challenge the district court’s findings with regard to damages.
    Specifically, defendants contend that the district court erred in finding that their breach of the SPA
    caused E-V lost revenues. In addition, defendants oppose the district court’s damages calculation
    on two grounds: that it was speculative and based on an improper baseline. On cross-appeal,
    plaintiffs claim that the district court erred in refusing to award prejudgment interest. We address
    each issue in turn.
    III.
    Pursuant to Rule 52 of the Federal Rules of Civil Procedure, a party may contest the
    sufficiency of the evidence supporting a district court’s findings following a bench trial. See Fed.
    R. Civ. P. 52(a)(5) (“A party may later question the sufficiency of the evidence supporting the
    findings, whether or not the party requested findings, objected to them, moved to amend them, or
    moved for partial findings.”). This court reviews sufficiency claims de novo, “without determining
    credibility or weighing evidence, and giving the prevailing party the benefit of all reasonable
    inferences.” Argentine v. United Steelworkers of Am., AFL-CIO, 
    287 F.3d 476
    , 483 (6th Cir. 2002).
    The district court should be reversed “only if reasonable minds could not come to a conclusion other
    than one favoring the movant.” K & T Enters., Inc. v. Zurich Ins. Co., 
    97 F.3d 171
    , 176 (6th Cir.
    1996). The district court’s findings of fact, however, may not be set aside unless clearly erroneous.
    Fed. R. Civ. P. 52(a)(6). Clear error exists “only when the reviewing court is left with the definite,
    -7-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    firm conviction that a mistake has been made.” Isabel v. City of Memphis, 
    404 F.3d 404
    , 411 (6th
    Cir. 2005).
    The SPA is governed in all respects by the laws of the state of Ohio. In Ohio, “[a] claimant
    seeking to recover for breach of contract must show damage as a result of the breach.” Textron Fin.
    Corp. v. Nationwide Mut. Ins. Co., 
    684 N.E.2d 1261
    , 1266 (Ohio Ct. App. 1996). “The damages
    awarded for a breach of contract should place the injured party in as good a position as it would have
    been in but for the breach. Such compensatory damages, often termed ‘expectation damages,’ are
    limited to actual loss, which loss must be established with reasonable certainty.” 
    Id. (quoting Doner
    v. Snapp, 
    649 N.E.2d 42
    , 44 (Ohio Ct. App. 1994)). Such expectation damages may include lost
    profits. However, to recover lost profits, a plaintiff must demonstrate that they are “the reasonable
    result of the breach, and that the profits are not remote and speculative.” 
    Id. at 1267.
    “The
    determination of the existence and amount of the lost profits is a question of fact.” Kosier v.
    DeRosa, 
    862 N.E.2d 159
    , 165 (Ohio Ct. App. 2006). Damages, like all other elements of a breach
    of contract claim, must be proven by a preponderance of the evidence. Langfan v. Carlton Gardens
    Co., 
    916 N.E.2d 1079
    , 1087 (Ohio Ct. App. 2009).
    A. Causation
    The district court determined that defendants’ breach of the SPA caused E-V to lose former
    clients, prospective clients, and a contract with Summit County. On appeal, defendants assert that
    the evidence was insufficient to find that the breach caused any of these losses. Upon review, we
    hold that the evidence was sufficient to support the district court’s findings with regard to E-V’s loss
    -8-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    of former and prospective clients, but was insufficient regarding the loss of a contract with Summit
    County.
    1. Former and Prospective Clients
    In its findings of fact and conclusions of law, the district court determined that defendants
    breached the SPA by failing to introduce established marketing relationships to E-V personnel,
    failing to maintain E-V marketing staff, closing E-V’s Columbus office, and eliminating the E-V
    brand. Acknowledging that the existence and amount of damage must be proven with “reasonable
    certainty,” the district court concluded that defendants’ “breach caused client attrition and prevented
    E-V from earning new clients[.]” This finding was reasonable and well-supported.
    First, the testimony elicited from numerous lay and expert witnesses indicated that marketing
    relationships and personnel, local presence, and branding were all significant factors affecting a
    TPA’s success. Moreover, defendants admitted that their actions caused the loss of former and
    prospective E-V clients. For example, Donald Baker, chairman, CEO, CFO, and treasurer of NABN,
    testified that defendants “killed off” the E-V brand and closed E-V’s Columbus office, causing the
    loss of existing E-V clients. Baker further acknowledged that defendants failed to commit the
    resources necessary to foster E-V’s growth. Accordingly, based upon the testimony elicited at trial
    and defendants’ admissions, the district court’s finding that the loss of former and prospective E-V
    clients was attributable to defendants’ breach was supported by sufficient evidence.
    Nevertheless, despite the above-referenced testimony, defendants contend that plaintiffs’
    causation evidence was insufficient because they failed to obtain direct testimony from any former
    -9-
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    or prospective E-V client. Without such testimony, defendants assert that E-V’s business failures
    could be attributable to any number of factors unrelated to the breach.1 This argument misses the
    mark for two reasons. First, while the testimony of former and prospective E-V clients may have
    provided helpful information regarding the issue of causation, defendants cite to no Ohio authority,
    and we find none, requiring plaintiffs to provide such direct evidence to establish causation. Indeed,
    the Ohio Court of Appeals has sanctioned the use of circumstantial evidence, and the reasonable
    inferences drawn therefrom, in making causation findings. See, e.g., Roelle v. Orkin Exterminating
    Co., No. 00AP-14, 
    2000 WL 1664865
    , at *8 (Ohio Ct. App. Nov. 7, 2000) (noting that a court could
    reasonably infer, based upon timing, that a previous termite infestation did not cause the damages
    at issue); accord Shred-It USA, Inc. v. Mobile Data Shred, Inc., 
    238 F. Supp. 2d 604
    , 608 (S.D. N.Y.
    2002) (noting that evidence was sufficient to establish that breach caused the loss of clients, even
    without direct client testimony).
    Second, in making its findings of fact regarding causation, the district court was in a position
    to weigh the evidence presented and give determinative credit to the evidence it found persuasive.
    See Westinghouse Elec. Corp. v. Dolly Madison Leasing & Furniture Corp., 
    326 N.E.2d 651
    , 656
    (Ohio 1975) (“Defendants suggested that other causes of the fire were possible, such as spontaneous
    1
    To support this argument, defendants repeatedly cite to Telxon Corp. v. Smart Media of
    Delaware, Inc., Nos. 22098, 22099, 
    2005 WL 2292800
    (Ohio Ct. App. Sept. 21, 2005). Telxon
    stands for the unremarkable principle that “damages must [be] directly caused by the wrongful
    breach, not by something else.” 
    Id. at *37.
    Telxon does not hold that direct evidence is required to
    prove causation, or that every conceivable cause of loss must be ruled out before causation may be
    established by a preponderance of the evidence.
    - 10 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    combustion, arson, or sparks from a locomotive. However, all these possible causes were questions
    of fact for the jury[.]”). Plaintiffs were not required to affirmatively disprove all possible causes of
    E-V’s losses outside of breach. Indeed, the Supreme Court of Ohio has noted that such a
    requirement “would impose a burden of proof analogous to the burden in criminal cases of proof
    beyond a reasonable doubt.” 
    Id. Instead, plaintiffs
    needed only to put forth enough evidence to
    prove, by a preponderance of the evidence, that defendants’ breach caused the loss of former and
    prospective E-V clients. The district court found that plaintiffs had met their burden, and the
    evidence was sufficient to support this finding.2
    2. Summit County
    In addition to their marketing and branding failures, the district court found that defendants
    breached the SPA by preventing plaintiffs from pursuing an opportunity with Summit County,
    causing the loss of a contract valued at $376,000 in annual revenue. Again, while not disputing the
    underlying breach, defendants assert that the evidence was insufficient to support the district court’s
    finding that their actions caused the loss of a contract with Summit County. We agree.
    The only evidence in the record pertaining to the opportunity with Summit County was the
    direct examination of Eggert. This testimony was accurately summarized by the district court as
    follows:
    2
    In holding that 15% of former client losses were attributable to the acquisition and the
    concomitant system conversion, the district court relied upon and credited the opinion of Todd
    Squilanti, who testified that a 15% loss in clients is generally expected to occur after an acquisition.
    Accordingly, defendants’ assertion that this percentage is “meaningless” is without merit.
    - 11 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    Eggert was a “lifelong friend” of Don Plusquellic, the mayor of Akron, Ohio. (Tr.
    387.) Eggert and his wife made a personal trip to Boston to support Mayor
    Plusquellic when he was installed as the president of the National Conference of
    Mayors in 2004. (Tr. 387-88 .) In Boston, Mayor Plusquellic introduced Eggert to
    the Executive Director of Summit County, Ohio[.] (Tr. 388.) Eggert testified that
    he “spent time on a couple of occasions during the conference speaking with the
    Executive Director,” who gave Eggert his business card and requested that Eggert
    call him. (Tr. 388.)
    When Eggert returned to Ohio, he contacted Ken Jones in Summit County’s Risk
    Management Department, which handled the county’s employee benefit plan. (Tr.
    389.) They set up a meeting in August of 2004, attended by Eggert, Chuck Bates,
    Jones, and Mayor Plusquellic. (Tr. 390, 391.) Eggert testified that he found the
    meeting to be “[v]ery favorable,” and a follow-up meeting was arranged between
    Eggert, Bates, and Jones to further discuss the program. (Tr. 390.)
    Eggert “immediately reported to Ron Dewsnup and Cheryl Tidwell the details of the
    meeting,” telling them that “it was a great opportunity,” that Mayor Plusquellic
    “attended and gave a strong reference to us and participated in the meeting and
    discussions about the program,” and that a follow-up meeting had been arranged.
    (Tr. 390-91.) At Dewsnup’s request, Eggert arranged for Tidwell to attend the
    follow-up meeting along with Eggert and Bates. (Tr. 391.) Just prior to that
    follow-up meeting, Tidwell, who was arriving from a different direction, met Eggert
    and Bates at a restaurant and advised them that Eggert and Bates “were to stay out
    of Summit County.” (Tr. 391-92.) She further advised them that Sandy Hahn, a
    sales representative of NABN, would be pursuing the Summit County opportunity.
    (Tr. 393.) If Hahn had secured the account, the revenue would not have been
    attributable to E-V. (Tr. 394.)
    Based upon this testimony, the district court found “that Defendant prevented Plaintiffs from taking
    advantage of the Summit County opportunity, which could have increased Revenue, thereby
    increasing the amount of monies owed Plaintiffs under the SPA.” However, the district court never
    made an express finding that, absent the breach, E-V was reasonably certain to obtain a contract with
    Summit County. See 
    Textron, 684 N.E.2d at 1266
    (holding that damages must be “established with
    reasonable certainty”).
    - 12 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    We hold that the evidence was insufficient to find that E-V was reasonably certain to obtain
    a contract with Summit County in the absence of defendants’ breach. McLellan testified that the
    average TPA only closes on 6 - 12% of the opportunities presented on an annual basis, and the
    district court credited this testimony, holding that E-V was reasonably certain to close on 6% of
    presented opportunities. While Eggert believed that the first meeting with Summit County was “very
    favorable,” there was no evidence indicating how likely it was that Summit County would eventually
    sign a contract with E-V. Indeed, when asked whether E-V was likely to obtain a contract with
    Summit County, Eggert merely noted that Summit County presented “a great opportunity.”
    Accordingly, the evidence was insufficient to support the finding that E-V was reasonably
    certain to have obtained a contract with Summit County in the absence of defendants’ breach. Upon
    remand, the district court must recalculate the amount of E-V’s lost profits, excluding those losses
    attributable to the Summit County contract.
    B. Damages Calculation
    In their second claim of error, defendants assert that the district court’s calculation of lost
    profits pertaining to the loss of prospective E-V clients was speculative. This argument is without
    merit.
    “Lost profits must be substantiated by calculations based on facts available or in evidence,
    otherwise they are speculative and uncertain.” Rhodes v. Rhodes Indus., Inc., 
    595 N.E.2d 441
    , 448
    (Ohio Ct. App. 1991). However, such damages need not be proven with mathematical precision.
    Rather, the amount of lost profits “may be reasonably estimated.” TJX Cos., Inc. v. Hall, 916 N.E.2d
    - 13 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    862, 869 (Ohio Ct. App. 2009). Accordingly, “[d]amages are not rendered uncertain because they
    cannot be calculated with absolute exactness. It is sufficient if a reasonable basis of computation is
    afforded, although the result be only approximate.” 
    Id. (internal quotation
    marks and citation
    omitted).
    In calculating damages, the district court relied upon the expert opinion of McLellan, who
    testified regarding the revenues an average TPA would be likely to obtain in central Ohio during the
    revenue period. This testimony was based upon McLellan’s appreciable experience in the TPA field.
    In addition, McLellan relied in substantial part on his knowledge of the central Ohio TPA market,
    knowledge obtained through his work with an E-V competitor, Central Benefits Insurance Company,
    commonly referred to as “CenBen.” Because this testimony constitutes “competent, credible
    evidence,” the district court’s damages calculation was not speculative. See Srail v. RJF Int’l Corp.,
    
    711 N.E.2d 264
    , 273 (Ohio Ct. App. 1998) (“When reviewing a damages award, an appellate court
    must not reweigh the evidence and may not disturb an award of damages unless it lacks support from
    any competent, credible evidence.”).
    Defendants assert that McLellan’s testimony was not credible because he relied upon
    statistics stemming from CenBen and local TPA averages, rather than statistics specific to E-V.
    However, it was not unreasonable for McLellan to rely upon numbers obtained from TPAs
    competing in the relevant market during the revenue period, rather than E-V’s prior performance,
    as the revenue period presented a market “exploding” with new opportunities. Moreover, the
    - 14 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    experiences of similar business enterprises3 is a proper factual basis upon which to calculate lost
    profits, Thomasville Furniture Indus., Inc. v. Elder-Beerman Stores Corp., 
    250 B.R. 609
    , 629 (S.D.
    Ohio 1998) (applying Ohio law) (citing AGF v. Great Lakes Heat Treating Co., 
    555 N.E.2d 634
    , 640
    (Ohio 1990)), and “[g]reat liberality is allowed the expert in determining the basis of his opinions[,]”
    Mannino v. Int’l Mfg. Co., 
    650 F.2d 846
    , 853 (6th Cir. 1981). While defendants had the opportunity
    to do so, they provided no evidence to contradict McLellan’s testimony. Accordingly, the district
    court’s damages award was supported by competent, credible evidence, and was not speculative.4
    See 
    Srail, 711 N.E.2d at 273
    .
    C. Baseline for Damages Calculation
    As their final claim of error, defendants assert that the district court selected an improper
    baseline in calculating damages. During his direct examination, Eggert testified that the base
    revenue amount represented the parties’ agreement as to the revenue E-V “would have expected on
    an annual basis from the existing business, E-V Benefits going on as a going concern, with no new
    3
    CenBen and E-V, both headquartered in Columbus, Ohio, were direct competitors in the
    central Ohio TPA market.
    4
    Defendants also assert that the district court “misconstrued” McLellan’s testimony regarding
    the underlying basis for his lost-profits calculations. This assertion is baseless. The district court
    held that an average TPA had 70-75 opportunities per year, and that each opportunity averaged 375
    covered employees. While these statistics stem from CenBen’s experience during the revenue
    period, McLellan testified that they were a reasonable basis upon which to extrapolate what E-V
    could have achieved in the central Ohio market during the revenue period. Accordingly, the district
    court did not misconstrue the opinions of McLellan.
    - 15 -

    Eggert, et al. v. Meritain Health, Inc., et al.
    business, no loss of clients” as a “straight line going forward[.]”5 Crediting this testimony, the
    district court used the base revenue amount as a starting point in calculating the revenues that likely
    would have been obtained by E-V in the absence of defendants’ breach.
    Defendants contend that the district court erred as a matter of law in ascribing this meaning
    to the base revenue amount, asserting that the clear and unambiguous language of the SPA indicates
    that the base revenue amount is nothing but a “fixed standard for calculation purposes only.”
    However, while defendants are correct that “clear and unambiguous [contracts] require no real
    interpretation or construction,” Fouty v. Ohio Dep’t of Youth Servs., 
    855 N.E.2d 909
    , 925 (Ohio Ct.
    App. 2006), defendants are incorrect in asserting that the SPA unambiguously supports their
    interpretation of the base revenue amount. Indeed, the SPA simply does not speak to the underlying
    meaning of the base revenue amount or how it was calculated. Rather, the SPA merely defines the
    term as “Four Million Two Hundred Ninety Eight Thousand Dollars ($4,298,000).” Because the
    SPA does not answer the question, the district court did not err in considering the testimony of
    Eggert regarding the significance of the base revenue amount. See Allason v. Gailey, 
    939 N.E.2d 206
    , 212 (Ohio Ct. App. 2010) (“If a contract, or term in a contract is reasonably susceptible to more
    than one meaning, then it is ambiguous and extrinsic evidence of reasonableness or intent can be
    employed.”).
    5
    At the time the SPA was signed, four of E-V’s existing clients were listed as “runout,”
    indicating that these clients had a contract with E-V that was not going to be renewed. However,
    the base revenue amount did not include projected revenue from these four clients. Accordingly,
    defendants’ assertion that the district court did not account for runout clients is incorrect.

    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    In addition, defendants contend that the district court’s use of the base revenue amount
    impermissibly shifted the burden of proof to defendants. This argument is unfounded. The district
    court correctly noted that the burden of proving the existence and amount of damages was on
    plaintiffs. Using the base revenue amount as a baseline did not alter this legal landscape.
    Nevertheless, defendants contend that using the base revenue amount as a baseline, rather than E-V’s
    actual revenues, created a presumption that the entire difference between these numbers was
    attributable to defendants’ breach. The district court, however, did not presume anything. The
    district court’s chosen calculation reflects its finding that the difference between E-V’s actual
    revenues and the base revenue amount represented losses caused by defendants’ breach, with certain
    listed exceptions. Accordingly, the district court did not err in using the base revenue amount as its
    baseline.
    IV.
    On cross-appeal, plaintiffs claim that the district court erred in refusing to award prejudgment
    interest. To begin, the parties dispute our standard of review. Plaintiffs assert that their entitlement
    to prejudgment interest is a question of law, to be reviewed de novo, while defendants contend that
    this court reviews the denial of prejudgment interest for an abuse of discretion. We conclude that
    under Ohio law, the appropriate standard of review is de novo.
    Defendants rely upon Conte v. General Housewares Corp., 
    215 F.3d 628
    (6th Cir. 2000), in
    asserting that abuse-of-discretion review is proper. In Conte, this court noted: “In a diversity case,
    state law governs the district court’s decision whether to award prejudgment interest, . . . which is
    - 17 -
    Nos. 10-3223/10-3282
    Eggert, et al. v. Meritain Health, Inc., et al.
    reviewed by this court for an abuse of discretion, see Stallworth v. City of Cleveland, 
    893 F.2d 830
    ,
    836 (6th Cir. 1990) (applying Ohio law).” 
    Id. at 633
    (citation omitted). However, Conte and
    Stallworth both involved the issue of prejudgment interest awarded pursuant to Ohio Revised Code
    (“ORC”) § 1343.03(C), which pertains to actions in tort. 
    Conte, 215 F.3d at 633
    ; 
    Stallworth, 893 F.2d at 836
    . Section 1343.03(C) requires a tort plaintiff to demonstrate his or her good-faith effort
    to obtain a settlement. See ORC § 1343.03(C) (providing that plaintiff must demonstrate that
    defendant “failed to make a good faith effort to settle the case and that [plaintiff] did not fail to make
    a good faith effort to settle the case[.]”). This good-faith determination is “within the sound
    discretion of the trial court” and reviewed for an “abuse [of] discretion[.]” Worrell v. Multipress,
    Inc., 
    543 N.E.2d 1277
    , 1285 (Ohio 1989).
    However, Ohio contract law is different. It does not require a good-faith finding to impose
    prejudgment interest on a contract award; all it requires is a favorable judgment:
    [W]hen money becomes due and payable upon any . . . instrument of writing, . . . the
    creditor is entitled to interest at the rate per annum determined pursuant to section
    5703.47 of the Revised Code, unless a written contract provides a different rate of
    interest in relation to the money that becomes due and payable, in which case the
    creditor is entitled to interest at the rate provided in that contract.
    ORC §1343.03(A). Accordingly, the issue of prejudgment interest in contract is a pure question of
    law, requiring de novo review. See Forest Hills Local Sch. Dist. Bd. of Ed. v. Huegel, Nos.
    CA2007-02-026, CA2007-02-032, 
    2008 WL 2102406
    , at *3 (Ohio Ct. App. May 19, 2008) (holding
    that because no “factual determinations” are required to determine entitlement to prejudgment
    interest on a contract award, the trial court’s decision is reviewed “de novo”).

    Eggert, et al. v. Meritain Health, Inc., et al.
    In this case, the district court denied prejudgment interest because plaintiffs failed to present
    evidence regarding the effect such interest would have on the adjusted amortization schedules.
    However, once it rendered a monetary judgment in favor of plaintiffs on the SPA, the district court
    lacked discretion to deny prejudgment interest. See Lincoln Elec. Co. v. St. Paul Fire & Marine Ins.
    Co., 
    210 F.3d 672
    , 693 (6th Cir. 2000) (applying Ohio law) (“If a favorable judgment award has been
    obtained by plaintiff, plaintiff has a right under [ORC §] 1343.03(A) to an interest award as a matter
    of law, and the trial judge has no discretion not to grant any interest award.”); Royal Elec. Constr.
    Corp. v. Ohio State Univ., 
    652 N.E.2d 687
    , 691-92 (Ohio 1995); Stoebermann v. Beacon Journal
    Publ’g Co., 
    894 N.E.2d 750
    , 758 (Ohio Ct. App. 2008) (internal quotation marks and citations
    omitted) (“[O]nce a plaintiff receives judgment on a contract claim, the trial court has no discretion
    but to award prejudgment interest under [ORC §] 1343.03(A).”). Accordingly, we reverse the
    district court’s order regarding prejudgment interest. Upon remand, the district court is directed to
    add prejudgment interest to its judgment.6
    6
    While the subordinated term notes provide for an interest rate of 5% per annum, the growth
    plan, which sets forth the payments to plaintiffs Eggert and Nickell, does not address the issue of
    interest. Plaintiffs assert that the 5% interest rate provided in the subordinated term notes also
    applies to the growth plan and defendants do not contest this assertion. Upon review of the SPA,
    we find that the growth plan incorporates the calculations provided in the SPA, which in turn
    incorporates the 5% interest rate in the subordinated term notes. Accordingly, Eggert and Nickell
    are entitled to prejudgment interest calculated at 5% per annum. See Christe v. GMS Mgmt. Co.,705
    N.E.2d 691, 693 (Ohio Ct. App. 1997) (“Where one instrument incorporates another by reference,
    both must be read together.”).

    V.
    In sum, we affirm in part, reverse in part, and remand. We hold that the evidence was
    insufficient to support the district court’s finding that the loss of the Summit County contract was
    attributable to defendants’ breach of the SPA. In addition, we hold that the district court erred as a
    matter of law in refusing to award prejudgment interest. In all other respects, we affirm the district
    court. Upon remand, the district court is directed to amend its damages award and enter a judgment
    consistent with this opinion.
