    SELYA, Circuit Judge.     The development of new drugs is
    a costly, time-consuming, and highly speculative enterprise.           In
    an effort to hedge their bets, drug companies sometimes opt to
    share the risks and rewards of product development with outside
    investors.    This appeal introduces us to that high-stakes world.
    The outcome turns primarily on a contract provision that the
    parties disparately view as a liquidated damages provision (and,
    thus, enforceable) or a penalty (and, thus, unenforceable).         A sum
    well in excess of $30,000,000 hangs in the balance.
    Following a lengthy bench trial, the district court held
    the key provision inapposite and, in all events, unenforceable.

    183 F. Supp. 3d 277
    , 321, 323 (D. Mass. 2016).              After careful
    consideration of a plethoric record, we reverse the district
    court's central holding, affirm its judgment in other respects,
    and remand for further proceedings (including the entry of an
    amended final judgment) consistent with this opinion.

    (Abbott), seeks to increase its return through litigation.                  In
    particular, Hancock aims to recover damages under its contract
    with Abbott or, in the alternative, to rescind that contract.              The
    parties' dispute is by now well-chronicled.           See John Hancock Life

    reader's familiarity with these opinions and rehearse here only
    those   facts     needed   to    place    this   appeal    into   a   workable
    perspective.
    A.    The Agreement.
    In late 1999 or early 2000 — the exact date is of no
    consequence — Hancock (a financial services company) and Abbott (a
    pharmaceutical manufacturer) entered into negotiations regarding
    a potential investment in a menu of new drugs that Abbott was
    developing.     The parties chose nine specific Program Compounds
    that they hoped would mature into commercially successful drugs to
    treat   various    afflictions    (such    as    cancer   and   urinary   tract
    blockages).     During these negotiations, both Hancock and Abbott
    were represented by seasoned counsel, who exchanged approximately
    forty drafts of the proposed contract over a period of a year or
    more.
    - 3 -
    On March 13, 2001, the parties signed a research funding
    agreement (the Agreement).         The Agreement is long and intricate,
    and we outline here only those provisions that are central to an
    understanding of the issues on appeal.
    In the Agreement, Abbott pledged to develop the Program
    Compounds in accordance with Annual Research Plans that Abbott
    would submit for each Program Year over the course of a four-year
    Program    Term.      These    Annual   Research       Plans    were   to    contain
    "detailed statement[s] of the objectives, activities, timetable
    and   budget   for    the    Research   Program       for    every   Program    Year
    remaining in the Program Term."               Abbott prepared the first such
    Annual Research Plan for attachment as an exhibit.
    The parties were to fund the development of the Program
    Compounds as specified in the Agreement and were meant to share in
    the profits.       Hancock's funding obligations are precisely defined
    in section 3.1 of the Agreement: it would make four annual Program
    Payments, ranging from $50,000,000 to $58,000,000 each, over the
    course of the Program Term (a total of $214,000,000).                        Section
    3.5, entitled "Hancock Funding Obligation," makes explicit that
    "Hancock's     entire    obligation     [under       the    Agreement]      shall   be
    limited to providing the Program Payments set forth in [s]ection
    3.1."     In return for its investment, Hancock receives emoluments
    based on the progress and success of the Program Compounds.                    These
    emoluments     include      payments    for    the    achievement      of    certain
    - 4 -
    milestones, such as the initiation of a clinical trial or U.S.
    Food and Drug Administration (FDA) approval.                It also receives
    royalties from any out-licensing or sales of the Program Compounds.
    The    Agreement   saddles     Abbott   with    both    annual   and
    cumulative spending obligations.         Annually, Abbott was responsible
    for meeting the Annual Minimum Spending Target; that is, it had to
    spend annually at least the sum of Hancock's contribution for that
    year, plus $50,000,000, plus any shortfall from the prior year's
    minimum spending target.        Cumulatively, Abbott had to spend "at
    least the Aggregate Spending Target" — defined as $614,000,000 —
    "during    the    Program   Term."    In     addition,     Abbott   is   "solely
    responsible for funding all Program Related Costs in excess of the
    Program Payments from . . . Hancock."2          These obligations comprise
    only Abbott's minimum spending commitment: that commitment is a
    floor, not a ceiling, and Abbott projected in its first Annual
    Research Plan that it would spend over one billion dollars (about
    five times Hancock's expected total contribution) through the end
    of 2004.
    In what turned out to be a prescient precaution, the
    Agreement anticipates that Abbott might not fulfill its spending
    commitment. In this respect, section 3.2 of the Agreement provides
    2 The district court assumed — and neither party disputes —
    that both Hancock's and Abbott's contributions are to be credited
    toward the Aggregate Spending Target.    See Hancock III, 183 F.
    Supp. 3d at 316.
    - 5 -
    that if Abbott "fail[ed] to fund the Research Program in accordance
    with" its obligations, "Hancock's sole and exclusive remedies" are
    those remedies "set forth in [s]ections 3.3 and 3.4" of the
    Agreement.       Section   3.3,   entitled     "Carryover     Provisions,"    is
    divided into two subsections.              If Abbott spends less than its
    Annual Minimum Spending Target, Hancock is allowed, under section
    3.3(a), to defer its annual Program Payments until Abbott makes up
    that shortfall.        Section 3.3(b) describes Hancock's remedies in
    the   event    that   Abbott   did   not    meet   its    cumulative   spending
    obligations:
    If Abbott does not expend on Program Related
    Costs the full amount of the Aggregate
    Spending Target during the Program Term,
    Abbott will expend the difference between its
    expenditures for Program Related Costs during
    the Program Term and the Aggregate Spending
    Target (the "Aggregate Carryover Amount") on
    Program Related Costs during the subsequent
    year commencing immediately after the end of
    the Program Term. If Abbott does not spend
    the Aggregate Carryover Amount on Program
    Related Costs during such subsequent year,
    Abbott will pay to . . . Hancock one-third of
    the Aggregate Carryover Amount that remains
    unspent by Abbott, within thirty (30) days
    after the end of such subsequent year.
    Section 3.4 permits Hancock to terminate future Program Payments
    under   certain       circumstances,   including         Abbott's   failure   to
    "reasonably demonstrate in its Annual Research Plan its intent and
    reasonable expectation to expend on Program Related Costs during
    - 6 -
    the Program Term an amount in excess of the Aggregate Spending
    Target."
    To complete the picture, the Agreement contains a full-
    throated integration clause.      Specifically, section 16.3 confirms
    that the "Agreement contains the entire understanding of the
    parties with respect to the subject matter hereof.        All express or
    implied agreements and understandings, either oral or written,
    with respect to the subject matter hereof heretofore made are
    expressly merged in and made a part of this Agreement."
    B.   The Fallout and the Litigation.
    After the Agreement was signed, Hancock made its first
    two   Program   Payments,   totaling   $104,000,000.      Even   so,   the
    relationship    quickly   began   to   fray.   Abbott    terminated    the
    development of several compounds in the first two years and
    significantly reduced its spending on the development of other
    compounds.      At the end of 2002, Abbott informed Hancock that
    Abbott's 2002 spending had been appreciably less than its Annual
    Research Plan had anticipated.         More troubling still, Abbott's
    preliminary research plan for 2003 projected a sharp reduction in
    spending for that year compared to its previous estimate and made
    no mention at all of expected 2004 spending. In September of 2003,
    Abbott belatedly proffered its 2003 Annual Research Plan, which
    did include some projected spending for 2004.           That submission,
    - 7 -
    though, further reduced total spending and admitted that Abbott
    would not reach the Aggregate Spending Target by the end of 2004.
    After reviewing this document, Hancock responded that,
    in view of the insufficient spending that Abbott was prepared to
    undertake, it regarded its obligation to make future Program
    Payments as null and void. Abbott's rejoinder was of little solace
    to Hancock: it submitted a preliminary 2004 Annual Research Plan,
    indicating that Abbott would expend well below its annual minimum
    contribution in 2003 and would fail to reach the Aggregate Spending
    Target through the end of 2004.             In both the final 2003 Annual
    Research Plan and the preliminary 2004 Annual Research Plan,
    however,   Abbott    predicted      that    it    would    reach    the   Aggregate
    Spending Target if 2005 spending were included.
    Unsettled     by    this   news,     Hancock    invoked      diversity
    jurisdiction, see 
    28 U.S.C. § 1332
    (a), and filed suit in the United
    States District Court for the District of Massachusetts.                        That
    suit sought a declaration that Abbott's failure to meet its
    spending commitments terminated Hancock's obligation to make the
    third and fourth Program Payments.                The district court granted
    summary judgment in favor of Hancock, holding that "Hancock's
    obligation    to    make   the    Program       Payments    for    2003   and   2004
    terminated when Abbott failed to demonstrate its 'intention and
    reasonable expectation' to meet the . . . Aggregate Spending Target
    within the four-year Program Term in its [Annual Research Plan]
    - 8 -
    for 2003."      Hancock I, 
    2005 WL 2323166
    , at *28 (quoting relevant
    language from the Agreement).            We affirmed.     See Hancock II, 
    478 F.3d at 2
    .
    Notwithstanding that Hancock was judicially relieved of
    its obligation to make its last two Program Payments, it retained
    its rights under the Agreement to whatever profits might be derived
    from any of the Program Compounds.              Hancock reports — and Abbott
    does not deny — that it has received slightly more than $14,000,000
    in milestone payments, out-licensing revenues, and management
    fees.     Comparing these receipts to its $104,000,000 investment,
    Hancock alleges that it incurred a net loss of almost $90,000,000
    on the benighted venture.
    Corporations seldom swallow losses of this magnitude
    complacently. And this case is no exception.                  In June of 2005 —
    while Hancock I was still unresolved — Hancock filed the instant
    action.     It asserted that Abbott had breached the Agreement in
    five    ways:   (1)   violating    its     representations      and   warranties
    through material misrepresentations and omissions regarding the
    development of the Program Compounds; (2) failing to provide
    Hancock with accurate spending projections; (3) refusing to pay
    Hancock one-third of the Aggregate Carryover Amount in accordance
    with    section   3.3(b)     of   the    Agreement;     (4)   failing   to   take
    appropriate     steps   to   out-license        the   Program   Compounds;   and
    (5) obstructing Hancock's audit of Abbott's compliance with the
    - 9 -
    Agreement.       Hancock further asserted that Abbott fraudulently
    induced Hancock to enter into the Agreement and, separately, that
    under the indemnification provision of the Agreement, Abbott was
    liable for Hancock's losses attributable to Abbott's defaults.
    In October of 2006 — roughly a month after this court's
    decision    in   Hancock    II    —   Hancock   sought    leave    to    amend   its
    complaint in this case to include a prayer for rescission. Hancock
    included the rescission claim in its first amended supplemental
    complaint (filed in December of 2006).
    The district court held a ten-day bench trial, which
    ended in 2008.       The court then solicited post-trial briefing and
    took the case under advisement.             It was not until April of 2016,
    though, that the court ruled.               In its opinion, the court made
    extensive findings of fact and conclusions of law.                      See Fed. R.
    Civ.   P.   52(a).     We    summarize      here   only   those     findings     and
    conclusions that are helpful to an understanding of the issues on
    appeal.
    To begin, the court found that Abbott violated its
    representations and warranties in three ways:
        Without   notifying       Hancock,    Abbott   paused      one    compound's
    development two days before the Agreement was signed, only to
    lift the hold on the day the Agreement was signed.                    Abbott
    canceled the compound three months later.               The court found
    that Abbott's failure to inform Hancock of the hold on the
    - 10 -
    compound's development was a material omission.                   See Hancock
    III, 183 F. Supp. 3d at 294, 306.
       Abbott represented that it intended to spend over $35,000,000
    in 2001 on developing a compound intended to treat chronic
    pain.       Yet Abbott knew before signing the Agreement that it
    actually intended to spend less than half that amount in 2001.
    The court found that "this misrepresentation . . . was
    material."         Id. at 308-09.
       Abbott made a further material misrepresentation as to an
    anti-infection compound.          See id. at 310.       Abbott represented
    that it expected once-a-day dosing would be possible for the
    four conditions that the drug was designed to treat.                        Yet,
    the court found that, at the time the Agreement was signed,
    Abbott did not have enough information to know that once-a-
    day   dosing       would   be   possible    for   the    two   more    severe
    conditions.         Since Abbott knew that once-a-day dosing was
    important, this misrepresentation was material.                   See id.
    Although these findings are emblematic of the rocky road
    down which the parties' relationship traveled, they proved to be
    hollow victories for Hancock.                The district court ruled that
    Hancock     did    not    sufficiently    prove    damages      attributable       to
    Abbott's      misrepresentations       and     omissions      because     Hancock's
    methods      for     calculating       damages     were       "speculative         and
    unconvincing."       Id. at 313.
    - 11 -
    The district court also found that Abbott breached the
    Agreement by providing Hancock with spending projections that
    assumed that every Program Compound would remain velivolant all
    the way to FDA approval.        Those projections, the court found, were
    submitted   in    lieu   of   more    realistic       projections        of   expected
    spending, which would have been adjusted for the risk that some
    compounds might be terminated.            See id. at 315.                Once again,
    Hancock could not recover for Abbott's breach because it did not
    adequately prove damages.        See id. at 316.
    Moving to an issue that has become central to this
    appeal, the district court concluded that Abbott had not reached
    the   Aggregate    Spending     Target.        The    court     determined       that,
    including Hancock's contributions, Abbott fell $99,100,000 short
    of the target.     See id. at 292.      Hancock argued that section 3.3(b)
    entitled it to one-third of this amount, that is, an award of
    approximately $33,000,000.           The district court disagreed.              While
    it    rejected    Abbott's    arguments    that       Hancock      was    judicially
    estopped from asserting its claim under section 3.3(b) and that
    the Agreement capped Abbott's spending obligation at $400,000,000,
    see id. at 317, it nonetheless concluded that Hancock was not
    entitled to any damages under section 3.3(b), see id. at 321, 323.
    To   reach   this    conclusion,         the   court    identified      an
    "apparent implied condition," which limited Abbott's liability
    under section 3.3(b) to pay Hancock one-third of the Aggregate
    - 12 -
    Carryover Amount to situations in which Hancock made all four
    Program Payments.     Id. at 318-19.    Striking Hancock a second blow,
    the court held in the alternative that even if section 3.3(b)
    applied, it constituted an unenforceable penalty.          See id. at 323.
    The   district    court   did   allow   recovery      for   one   of
    Hancock's breach-of-contract claims.        It ruled that in the course
    of Hancock's audit of Abbott's compliance, Abbott "fail[ed] to
    provide information and material necessary for Hancock's vendor
    . . . successfully to conduct an audit."           Id. at 316.     The court
    ordered Abbott to pay Hancock the cost of the audit, which amounted
    to $198,731.     See id.
    Turning to Hancock's rescission claim, the court struck
    that claim as "wholly irrelevant or impertinent."                Id. at 303.
    The court reasoned, inter alia, that rescission was inconsistent
    with the enforcement of the Agreement and that Hancock had chosen
    (in Hancock I) to enforce the Agreement.         See id. at 302-03.      Under
    the doctrine of election of remedies, it could not both affirm the
    contract and simultaneously seek its rescission.          See id.
    Finally, the district court rebuffed Hancock's claim
    that Abbott was obligated under the Agreement to indemnify it for
    the   losses   that   it    incurred.      The   court   ruled    that    this
    indemnification provision only applied to claims by third parties.
    See id. at 326.
    - 13 -
    When the smoke cleared, the court below awarded Hancock
    $198,731 in damages for Abbott's frustration of the audit, together
    with $110,395.34 in prejudgment interest (a total judgment of
    $309,126.34).       See id.   This timely appeal ensued.
    II.     ANALYSIS
    Hancock's    appeal      challenges     the       district    court's
    conclusion that its remedies under section 3.3(b) are contingent
    on its making all four Program Payments.             Hancock also challenges
    the   district     court's    alternative      holding   that    those    remedies
    constitute an unenforceable penalty.             Finally, Hancock challenges
    the order striking its rescission claim.
    We take a layered approach to these challenges. We first
    consider Abbott's contention that recovery under section 3.3(b)
    should be barred on grounds rejected by the district court.                       We
    then address the grounds upon which the district court relied.
    Those    grounds    are   attacked     by   Hancock,     and    we   address      the
    components of Hancock's asseverational array one by one.                    We end
    with a brief comment on prejudgment and postjudgment interest.
    We    approach   these    several    issues   mindful        that    the
    Agreement    contains     a   choice-of-law      provision      specifying       that
    Illinois law governs.         In line with this provision and with the
    parties' acquiescence, we apply the substantive law of Illinois
    (except where otherwise specifically noted).                    See McCarthy v.
    Azure, 
    22 F.3d 351
    , 356 n.5 (1st Cir. 1994) (explaining that "a
    - 14 -
    reasonable choice-of-law provision in a contract generally should
    be respected").
    As a general matter, issues of contract interpretation
    engender de novo review under Illinois law.      See St. Paul Mercury
    Ins. v. Aargus Sec. Sys., Inc., 
    2 N.E.3d 458
    , 478 (Ill. App. Ct.
    2013).    A reviewing court's principal task in interpreting a
    contract is to divine the parties' intent, which is manifested
    most clearly by "the plain and ordinary meaning of the language of
    the   contract."   
    Id.
        When    a   fully   integrated   contract   is
    unambiguous on its face, the court will determine its meaning from
    its language alone. See Air Safety, Inc. v. Teachers Realty Corp.,
    
    706 N.E.2d 882
    , 884 (Ill. 1999).      The court below concluded that
    the Agreement was unambiguous in its pertinent aspects, see Hancock
    III, 183 F. Supp. 3d at 318, 320, and neither party contests this
    conclusion.   We agree.   Thus, the question reduces to what that
    language means.
    According to Hancock, section 3.3(b) requires Abbott to
    pay as liquidated damages one-third of the Aggregate Carryover
    Amount, that is, one-third of the difference between the Aggregate
    Spending Target ($614,000,000) and the combined amount actually
    spent by the parties ($514,900,000).      Abbott disagrees with this
    proposition for several reasons, which we examine below.        All of
    these reasons posit that the remedies limned under section 3.3(b)
    are available only when Hancock has made all four Program Payments,
    - 15 -
    notwithstanding that Hancock's cessation of Program Payments was
    due to Abbott's breach.
    A.    Abbott's Rejected Defenses.
    Abbott    advances    four   rationales   in   support   of   its
    conclusion, two of which were rejected by the district court.           We
    start with those rejected arguments.
    As an initial matter, we note that those arguments are
    properly before us.      Although Abbott has not filed a cross-appeal,
    we have jurisdiction to consider a prevailing party's alternative
    arguments in defense of a judgment where, as here, the arguments
    were made below.        See Neverson v. Farquharson, 
    366 F.3d 32
    , 39
    (1st Cir. 2004).     In this instance, then, Abbott is entitled to
    argue for affirmance of portions of the district court's judgment
    on any ground asserted in the district court.       See Mass. Mut. Life
    Ins. Co. v. Ludwig, 
    426 U.S. 479
    , 481 (1976) (per curiam); United
    States v. Matthews, 
    643 F.3d 9
    , 12 (1st Cir. 2011).        The fact that
    no cross-appeal has been filed does not lessen this entitlement.
    See Neverson, 
    366 F.3d at 39
    .
    1.   Judicial Estoppel.       Abbott asserts that Hancock's
    interpretation of section 3.3(b) is foreclosed by principles of
    judicial estoppel.        The district court brushed this assertion
    aside, see Hancock III, 183 F. Supp. 3d at 317, and so do we.
    Abbott assumes that federal law applies to its judicial
    estoppel defense.       Yet, "[a]s judicial estoppel appears neither
    - 16 -
    clearly    procedural       nor   clearly   substantive,    there   may   be    a
    legitimate question as to whether federal or state law . . . should
    supply    the   rule   of    decision."     Alt.   Sys.    Concepts,   Inc.    v.
    Synopsys, Inc., 
    374 F.3d 23
    , 32 (1st Cir. 2004).               Here, however,
    Hancock has not challenged the application of federal law to this
    issue, and "a federal court sitting in diversity is free, if it
    chooses, to forgo independent analysis and accept the parties'
    agreement" as to which law applies.            
    Id.
     (quoting Borden v. Paul
    Revere Life Ins. Co., 
    935 F.2d 370
    , 375 (1st Cir. 1991)).                      We
    proceed accordingly.3
    Generally speaking, judicial estoppel "precludes a party
    from asserting a position in one legal proceeding which is contrary
    to a position [that] it has already asserted in another."              Patriot
    Cinemas, Inc. v. Gen. Cinema Corp., 
    834 F.2d 208
    , 212 (1st Cir.
    1987).     The doctrine "should be employed when a litigant is
    'playing fast and loose with the courts,' and when 'intentional
    self-contradiction is being used as a means of obtaining unfair
    advantage.'"     
    Id.
     (quoting Scarano v. Cent. R. Co., 
    203 F.2d 510
    ,
    513 (3d Cir. 1953)).
    3 At any rate, federal law and Illinois law do not appear to
    differ materially with respect to the elements of judicial
    estoppel.   Compare, e.g., Patriot Cinemas, Inc. v. Gen. Cinema
    Corp., 
    834 F.2d 208
    , 212 (1st Cir. 1987), with, e.g., Seymour v.
    Collins, 
    39 N.E.3d 961
    , 973 (Ill. 2015).
    - 17 -
    Abbott claims that, in Hancock I, Hancock argued that
    "the Aggregate Spending Target represents the 'combined total' of
    the parties' defined minimum and maximum contributions, i.e., $400
    million from Abbott and approximately $200 million from Hancock,
    and that the very purpose of the Agreement was for them to share
    the financial burdens . . . in that ratio."          In support, Abbott
    points to two statements made by Hancock in the course of Hancock
    I: that it (Hancock) was "to share the cost of certain research
    and development activities" and that the Aggregate Spending Target
    was "[t]he combined total of . . . Hancock's maximum funding
    contribution and Abbott's minimum funding contribution."             These
    statements do not bear the weight that Abbott loads upon them: the
    statement that costs would be shared says nothing about the amount
    that each party would contribute, and the references to maximum
    and   minimum   contributions   do   not   necessarily   import   specific
    dollar amounts.      Indeed, the raison d'être for the Hancock I
    litigation was Hancock's desire to obtain a declaration that its
    maximum contribution should be limited to $104,000,000 (in which
    event, Abbott's minimum contribution — on Hancock's view of the
    case — would be $510,000,000).
    The short of it is that we discern no friction between
    Hancock's position in Hancock I and its position in the case at
    hand.   Consequently, we hold — as did the district court — that
    - 18 -
    Hancock    is     not     judicially   estopped     from   advancing     its
    interpretation of section 3.3(b).
    2.     Abbott's "Cap" Defense.       Abbott next contends that
    its spending obligations are capped.              In its view, the plain
    language of the Agreement shows that Abbott is not, under any
    circumstances, "required to spend more than its minimum $400
    million share."         Noting that section 3.5 provides that "Abbott
    shall be solely responsible for funding all Program Related Costs
    in excess of the Program Payments from . . . Hancock" and that
    section 3.1 defines Hancock's Program Payments as four installment
    payments totaling $214,000,000 that "Hancock shall make," Abbott
    suggests   that    its    payment   responsibility    is   capped   at   the
    difference between the Aggregate Spending Target and the sum of
    Hancock's four Program Payments.             The district court disagreed
    with this suggestion, see Hancock III, 183 F. Supp. 3d at 317, as
    do we.
    Under Illinois law, "[a] contract must be construed as
    a whole, viewing each provision in light of the other provisions."
    Thompson v. Gordon, 
    948 N.E.2d 39
    , 47 (Ill. 2011).          To countenance
    Abbott's reading, we would have to cover much of the Agreement in
    Magic Marker.      For example, section 3.5 does not refer to either
    Hancock's $214,000,000 contribution or its four Program Payments;
    rather, it refers only to Hancock's Program Payments in general.
    And even though section 3.1 refers to four installments totaling
    - 19 -
    $214,000,000, section 3.4 delineates several conditions which, if
    not complied with, "shall terminate" any obligation on Hancock's
    part "to make any remaining Program Payments."      Given the language
    of section 3.4, Program Payments, as used in section 3.5, must
    mean whatever quantum of Program Payments Hancock is obligated to
    make under the Agreement — an amount that may be less than
    $214,000,000.    We agree with the district court that the natural
    reading of section 3.5 is that "Abbott should be the only party
    responsible     for    making   payments   in   excess   of   Hancock's
    contribution, not that Abbott should be responsible for paying
    only the excess of the Program Payments."         Hancock III, 183 F.
    Supp. 3d at 318.      Considering that the obvious purpose of section
    3.5, which is entitled "Hancock Funding Obligation," is to set a
    ceiling for Hancock's contributions, that paragraph would be a
    curious place for the parties to tuck away a hidden limit on
    Abbott's funding obligations.
    We add, moreover, that Abbott's theory does not account
    for section 3.2, which is entitled "Abbott Funding Obligation."
    This provision describes Abbott's obligation, in part, as spending
    "at least the Aggregate Spending Target during the Program Term."
    In other words, Abbott's spending obligation is not expressed in
    a fixed $400,000,000 lump sum but, rather, is expressed in terms
    of Abbott's commitment to help reach the Aggregate Spending Target.
    By linking Abbott's funding obligation to the Aggregate Spending
    - 20 -
    Target, section 3.2 appears to address the precise scenario in
    which Hancock's obligation to make all four Program Payments has
    been relieved under section 3.4.
    If the parties had wanted to restrict Abbott's minimum
    contribution to $400,000,000, they surely would have said so: such
    a term easily could have been inserted in the Agreement.           In
    sections 3.1 and 3.5, the parties capped Hancock's contribution at
    a fixed amount, but they elected not to impose such a cap when
    describing Abbott's contribution in section 3.2.     A court should
    be reluctant to infer terms that parties easily could have included
    in a contract when the parties themselves chose not to include
    such terms.    See Klemp v. Hergott Grp., Inc., 
    641 N.E.2d 957
    , 962
    (Ill. App. Ct. 1994).    We hold, therefore, that the plain language
    of the Agreement does not impose a ceiling of $400,000,000 on
    Abbott's minimum contributions.
    B.   Effect of Hancock's Failure to Complete Program Payments.
    The district court held, and Abbott echoes on appeal,
    that Abbott's obligation to pay under section 3.3(b) was discharged
    when Hancock failed to make all four Program Payments. See Hancock
    III, 183 F. Supp. 3d at 319-20.    The court reached this conclusion
    notwithstanding our earlier decision relieving Hancock of its
    obligation, in light of Abbott's breach, to make the third and
    fourth Program Payments.    See id. at 321; see also Hancock II, 
    478 F.3d at 9
    .
    - 21 -
    The district court relied principally on a Restatement
    provision   that   "[a]   party's   failure   to   render   or   to   offer
    performance may . . . affect the other party's duties . . . even
    though failure is justified by the non-occurrence of a condition."
    Restatement (Second) of Contracts § 239(1) (Am. Law Inst. 1981).
    In the district court's view, Hancock's refusal to make its last
    two Program Payments, even though excused by Abbott's breach, was
    a partial failure to render performance, which shielded Abbott's
    obligation to pay under section 3.3(b).        See Hancock III, 183 F.
    Supp. 3d at 319.
    This analysis is flawed.   Hancock did not fail to render
    performance in any meaningful sense but, rather, made timely
    Program Payments until Abbott, by its non-performance, pulled the
    rug out from under the deal.        In such circumstances, we do not
    think that Abbott's breach can fairly be considered the "non-
    occurrence of a condition" within the purview of Restatement
    (Second) of Contracts section 239(1).
    If more were needed, section 239 is not the law of
    Illinois.    Neither Abbott nor the district court has identified
    any reported Illinois case that so much as hints at the adoption
    in that jurisdiction of section 239.4 "[A]s a federal court sitting
    4 The district court acknowledged that no Illinois authority
    supports its interpretation of section 239. See Hancock III, 183
    F. Supp. 3d at 319. In an attempt to fill this gap, the court
    cited to an intermediate state court opinion from a state other
    - 22 -
    in diversity jurisdiction, we ought not 'stretch state precedents
    to reach new frontiers.'"    Rared Manchester NH, LLC v. Rite Aid of
    N.H., Inc., 
    693 F.3d 48
    , 54 (1st Cir. 2012) (quoting Porter v.
    Nutter, 
    913 F.2d 37
    , 41 (1st Cir. 1990)).          Put another way,
    "[c]oncerns both of prudence and of comity argue convincingly that
    a federal court sitting in diversity must hesitate to chart a new
    and different course in state law."       
    Id.
       Here, we decline to
    stretch inhospitable facts and, in the bargain, import an entirely
    novel principle into the jurisprudence of Illinois law.
    That ends this aspect of the matter.      For both of the
    reasons discussed above, it follows that the district court erred
    in holding that Hancock's excused failure to complete the making
    of its Program Payments foreclosed relief under section 3.3(b) of
    the Agreement.
    C.   The "Implied Condition" Theory.
    The district court's decision as to the inapplicability
    of section 3.3(b) also rests on a second pillar:    the court's view
    that the pertinent portions of the Agreement contain an apparent
    implied condition.     The court wrote that "the Agreement was not
    intended for [s]ection 3.3(b) to apply in situations where Hancock
    than Illinois. See 
    id.
     (citing Kaufman v. Byers, 
    823 N.E.2d 530
    ,
    537 (Ohio Ct. App. 2004)). Abbott adds only an unpublished Fifth
    Circuit opinion and another intermediate state court decision, not
    from Illinois. See Khan v. Trans Chem. Ltd., 
    178 F. App'x 419
    ,
    426 (5th Cir. 2006) (per curiam); Facto v. Pantagis, 
    915 A.2d 59
    ,
    63 (N.J. Super. Ct. App. Div. 2007).
    - 23 -
    contributed substantially less than 35% of the total funding."
    Hancock III, 183 F. Supp. 3d at 320.                   Thus, the court seems to
    have   discerned      an     implied    term    to    the    effect   that   Abbott's
    "obligation under [s]ection 3.3(b) is contingent upon Hancock's
    contribution of the full $214 million under [s]ection 3.1."                       Id.
    at 318.       On appeal, Abbott clasps this line of defense to its
    corporate bosom.
    It is an elementary rule of contract interpretation that
    "[i]f the words in [a] contract are clear and unambiguous, they
    must   be     given    their       plain,   ordinary        and   popular    meaning."
    Thompson, 
    948 N.E.2d at 47
    ; see Shields Pork Plus, Inc. v. Swiss
    Valley Ag Serv., 
    767 N.E.2d 945
    , 949 (Ill. App. Ct. 2002) ("[I]f
    the contract terms are unambiguous, the parties' intent must be
    ascertained exclusively from the express language of the contract
    . . . .").      Consonant with that rule, Illinois courts ordinarily
    "will not add terms to an agreement when the agreement is silent
    about those specific terms."                Frederick v. Prof'l Truck Driver
    Training Sch., Inc., 
    765 N.E.2d 1143
    , 1151 (Ill. App. Ct. 2002).
    This rule applies with particular force "when the added language
    would clearly change the plain meaning of the agreement," 
    id.,
     and
    even   more    so     when    an    agreement    is    "completely     integrated,"
    Policemen's Benev. Labor Comm. v. County of Kane, 
    973 N.E.2d 1024
    ,
    1032 (Ill. App. Ct. 2012).
    - 24 -
    To be sure, there are limited circumstances in which a
    court may, by inference, import terms into a contract.                          One such
    exception holds that when a contract cannot be administered without
    some term that is critical to an assessment of the parties' rights
    and duties, a court may fill the gap and supply a reasonable term.
    See Barnes v. Michalski, 
    925 N.E.2d 323
    , 336 (Ill. App. Ct. 2010).
    But   that     device    is    to    be    employed      sparingly   and    with     great
    circumspection:         "[a]lthough        a    court     can   declare    an    implied
    covenant to exist, that is only where there is in the express
    contract . . . a satisfactory basis which makes it necessary to
    imply certain duties and obligations in order to effect the
    [parties'] purposes . . . ."                 Mid-W. Energy Consultants, Inc. v.
    Covenant Home, Inc., 
    815 N.E.2d 911
    , 916 (Ill. App. Ct. 2004).
    Another exception holds that a court may sometimes infer a contract
    term when the circumstances are so unforeseeable that the parties
    could    not    reasonably          have   been   expected      to   include     a    term
    addressing the situation.             See Dato v. Mascarello, 
    557 N.E.2d 181
    ,
    183-84   (Ill.     App.       Ct.    1989)     (citing    Restatement      (Second)    of
    Contracts § 204).         This, too, is a narrow exception that applies
    only "when the parties to an agreement entirely fail to foresee
    the situation which later occurs and gives rise to the dispute."
    Id. at 183.
    The inferred term proposed by the district court and
    embraced by Abbott does not fit into any of the isthmian exceptions
    - 25 -
    to the general rule.    For one thing, inferring such a term is in
    no way essential to administering the Agreement.              The formula
    adumbrated in section 3.3(b) is entirely workable as it stands,
    both when Hancock makes all four Program Payments and when it does
    not. Courts should not add a new contractual term simply to assist
    one party to a contract in obtaining a better bargain.            See Klemp,
    
    641 N.E.2d at 962
    .
    For another thing, the scenario that developed here was
    readily foreseeable.     As drafted, section 3.2 affords Hancock
    remedies under both sections 3.3 and 3.4 with respect to any
    underspending by Abbott.     Section 3.4 permits Hancock to terminate
    its future Program Payments during the Program Term. It was surely
    foreseeable, from the outset, that if Hancock did not make all
    four   Program   Payments,   Abbott   might   not   reach   the   Aggregate
    Spending Target.     In that event, one would assume that Hancock
    would exercise its section 3.3(b) rights — yet nothing in the
    Agreement diminishes Abbott's obligations under section 3.3(b) if
    and when Hancock invokes section 3.4.         This court has no license
    to engraft a new contractual term to address a wholly foreseeable
    concatenation of events.
    We add, moreover, that section 3.2 lays out Abbott's
    funding obligations in both annual and cumulative increments.
    Cumulatively, it requires that Abbott spend "at least the Aggregate
    Spending Target during the Program Term."           If Abbott "fail[s] to
    - 26 -
    fund the Research Program in accordance with this [s]ection," then
    "Hancock's sole and exclusive remedies . . . are set forth in
    [s]ections 3.3 and 3.4."     The fact that the Agreement lists the
    remedies conjunctively must mean that Hancock is not limited to
    one or the other in the event of a breach by Abbott.       See Manor
    Healthcare Corp. v. Soiltest, Inc., 
    549 N.E.2d 719
    , 725 (Ill. App.
    Ct. 1989) ("The words 'and' and 'or' ordinarily are not commutual
    terms; they should not be considered interchangeable absent strong
    supporting reasons.").     Nor does anything else in the Agreement
    suggest the contrary.
    In all events, section 3.3(b) is pointed: "[i]f Abbott
    does not spend the Aggregate Carryover Amount" during the fifth
    year (that is, if Abbott does not reach the Aggregate Spending
    Target during the year following the four-year Program Term),
    "Abbott will pay to . . . Hancock one-third of the Aggregate
    Carryover Amount that remains unspent by Abbott, within thirty
    (30) days after the end of such subsequent year."    Plainly, Abbott
    did not spend the Aggregate Carryover Amount within the specified
    time frame, and any term excusing Abbott from performance is
    conspicuously lacking.
    Notwithstanding this clear language, the district court
    held (and Abbott argues on appeal) that section 3.3(b) was intended
    only to preserve a fixed funding ratio (65/35) in situations in
    which Hancock made all four Program Payments.       See Hancock III,
    - 27 -
    183 F. Supp. 3d at 319-20.       The genesis for this holding is the
    notion that, if everything went smoothly, the funding ratio between
    Abbott and Hancock would have been approximately 65% to 35% because
    Abbott would have contributed $400,000,000 and Hancock would have
    contributed $214,000,000.      Seizing upon this ratio, the district
    court    concluded     that,   under     section     3.3(b),     some     rough
    approximation of it obtained "in almost every situation" in which
    Hancock made all four Program Payments and Abbott nevertheless
    failed to reach the Aggregate Spending Target.           Id. at 319.       With
    this hypothesis in mind, the court surmised that the sole purpose
    of section 3.3(b) was to guarantee the same funding ratio in
    situations in which Hancock makes all four Program Payments but
    Abbott underspends.      See id. at 320.
    The district court's logic does not withstand scrutiny.
    Although section 3.3(b) may preserve some semblance of the 65/35
    ratio when Hancock makes all four Program Payments, it does not
    follow   that    section   3.3(b)      may   be    invoked    only   in    such
    circumstances.       After all, the Agreement's text does not limit
    section 3.3(b) to situations in which Hancock has made all four
    Program Payments.      Equally as important, the 65/35 ratio is not
    mentioned anywhere in the text of section 3.3.               Here, things did
    not go smoothly; Abbott failed to pay its share of the freight; as
    a result, Hancock was excused from making its last two Program
    Payments; and the 65/35 ratio never materialized.                Indeed, the
    - 28 -
    Hancock II panel anticipated our holding and expressly rejected
    Abbott's claim that the Agreement "required Hancock to spend half
    as much as Abbott."      
    478 F.3d at
    8 n.4.
    That rejection was inevitable, given that the Agreement
    both anticipates and allows a spectrum of potential funding ratios
    depending on the circumstances.                 To offer one example (out of
    several possible examples), Abbott's first Annual Research Plan
    proposed spending roughly five times more than Hancock's expected
    $214,000,000     contribution.        We       conclude,       therefore,     that   the
    existence of a 65/35 funding ratio under one set of facts cannot
    contradict the plain language of the Agreement.
    At the expense of carting coal to Newcastle, we remark
    the   obvious:   a    fixed   funding      ratio    in     a    contract    with     over
    $600,000,000     at   stake   is    not    a    mere   bagatelle.          It   strains
    credulity to think that parties who wanted such an important term
    to apply across the board would fail to include that term (or
    anything like it) in their contract.              This is especially true when
    one considers that we are dealing with a fully integrated contract
    between sophisticated parties represented by experienced lawyers,
    who labored through approximately forty drafts of a detailed
    document over the course of a year or more.                          See Policemen's
    Benev., 973 N.E.2d at 1032 (refusing to add term to "completely
    integrated     agreement");        Mid-W.       Energy,        
    815 N.E.2d at
       916
    - 29 -
    (declining to add term to "clear and unambiguous" contract between
    sophisticated commercial parties).
    In this regard, we deem it significant that the parties
    obviously knew how to include a funding ratio in a contract.
    Section 3.4 of the Agreement provides for a specified funding ratio
    in particular circumstances (not applicable here).              The inclusion
    of a fixed spending ratio in one section of a contract but not in
    another creates a compelling basis for inferring that the parties
    deliberately chose to omit any fixed spending ratio from the latter
    provision.    See generally Thompson, 
    948 N.E.2d at 47
     (holding that
    use of different terms in different sections of contract warrants
    presumption that sections have different meanings); cf. Hamilton
    v. Conley, 
    827 N.E.2d 949
    , 957 (Ill. App. Ct. 2005) ("[W]here one
    section of a statute contains a particular provision, omission of
    the same provision from a similar section is significant to show
    different legislative intent for the two sections."               (quoting In
    re   D.F.,    
    802 N.E.2d 800
    ,    816     (Ill.   2003)   (Freeman,   J.,
    concurring))).
    The    district   court's    characterization      of   Hancock's
    interpretation as "unreasonable" and "perverse," Hancock III, 183
    F. Supp. 3d at 320, is insupportable.5             The court emphasized its
    5 In point of fact, the district court's reading is less
    reasonable than a plain-language reading.     Under the district
    court's construction, if Abbott shirks its funding obligations
    during the Program Term, Hancock faces a Hobson's choice: it must
    - 30 -
    fear that any other reading would give Hancock a "windfall."         Id.
    (quoting Roboserve, Inc. v. Kato Kagaku Co., 
    78 F.3d 266
    , 278 (7th
    Cir. 1996)).      But this fear is misplaced: though the existence of
    an alleged windfall may have some role in determining whether
    section 3.3(b) is enforceable as a liquidated damages provision,
    see infra Part II(D), a court's subjective belief that contract
    terms may produce a windfall does not, without more, empower it to
    disregard the plain meaning of those contract terms.         Here, there
    is no "more" — and in this case, as in virtually every case, it is
    perilous for a court to attempt to determine the intentions of
    contracting parties through its view of the fairest or most
    commercially reasonable way in which to construct a transaction.
    "[W]hat seems commercially unreasonable to a court [may] not [have]
    seem[ed] so to the parties."     XCO Int'l Inc. v. Pac. Sci. Co., 
    369 F.3d 998
    , 1005 (7th Cir. 2004).         Confronted with an unambiguous
    and   fully    integrated   contract,   negotiated   at   arms-length,   a
    court's duty is to give force to the agreement's plain language.
    To sum up, the condition that the district court imposed
    on Abbott's performance under section 3.3(b) is not found in the
    language of the Agreement, which was fully integrated by virtue of
    either withhold its future Program Payments (thus forgoing its
    right to the damages that flow from Abbott's underspending) or
    continue to make its Program Payments (thus throwing good money
    after bad).
    - 31 -
    section 16.3.6     We will not subvert the plain language of the
    Agreement by plucking out of thin air a term that the parties
    easily could have included but chose to forgo.            See St. Paul
    Mercury, 2 N.E.3d at 478.    Simply put, the Agreement does not make
    Abbott's obligation under section 3.3(b) contingent on Hancock's
    completion of all four Program Payments.
    D.     Enforceability of Section 3.3(b) Remedies.
    As is true in many jurisdictions, Illinois contract law
    distinguishes between liquidated damages (generally enforceable)
    and penalties (generally unenforceable).          A liquidated damages
    clause is one that provides in advance that a breaching defendant
    will pay "a specific amount for a specific breach." Jameson Realty
    Grp. v. Kostiner, 
    813 N.E.2d 1124
    , 1131 (Ill. App. Ct. 2004).        The
    purpose of such a clause "is to provide parties with a reasonable
    predetermined damages amount where actual damages may be difficult
    to ascertain."     Karimi v. 401 N. Wabash Venture, LLC, 
    952 N.E.2d 1278
    , 1290 (Ill. App. Ct. 2011).             At least in theory, such
    provisions    minimize   uncertainty   and   reduce   litigation   costs,
    easing the burden on both the parties and the judicial system.
    6 The district court did say that "other provisions in the
    contract explicitly state that Abbott is obligated to comply with
    [s]ection 3.3(b) only if Hancock contributes all four of the
    Program Payments." Hancock III, 183 F. Supp. 3d at 318. However,
    the court never identified any such provisions, and we have found
    none.
    - 32 -
    See Restatement (Second) of Contracts § 356 cmt. a.       Penalties are
    a horse of a different hue.   When the sum or formula that is agreed
    upon in advance is not reasonably correlated with future damages
    and instead acts either as a threat to secure performance or as a
    punishment for non-performance, the provision is an unenforceable
    penalty.   See Inland Bank & Trust v. Knight, 
    927 N.E.2d 777
    , 782
    (Ill. App. Ct. 2010).
    Nomenclature is not dispositive.      Whether a provision is
    held to be a liquidated damages provision or a penalty provision
    depends on the nature of the provision, not on how it is labeled.
    See Penske Truck Leasing Co. v. Chemetco, Inc., 
    725 N.E.2d 13
    , 19
    (Ill. App. Ct. 2000).
    In this instance, Abbott agreed to section 3.3(b) after
    protracted arm's-length negotiations in which both sides were
    represented by seasoned counsel.       Abbott now asks us to relieve it
    of this bargained-for obligation on the ground that the obligation
    constitutes a penalty that the law of Illinois does not tolerate.
    As the party resisting enforcement of section 3.3(b), Abbott bears
    the burden of proving that the provision imposes an impermissible
    penalty rather than a permissible means of measuring liquidated
    damages.   See XCO Int'l, 
    369 F.3d at 1003
    ; Penske, 
    725 N.E.2d at 20
    .   Because   the   validity   and    enforceability   of   a   putative
    liquidated damages provision presents a question of law, see Fleet
    Bus. Credit, LLC v. Enterasys Networks, Inc., 
    816 N.E.2d 619
    , 633
    - 33 -
    (Ill. App. Ct. 2004), we review de novo the district court's
    determination that section 3.3(b) is an unenforceable penalty, see
    Kunelius v. Town of Stow, 
    588 F.3d 1
    , 13 (1st Cir. 2009).
    There is no hard-and-fast rule for separating liquidated
    damages provisions from penalty provisions.                Instead, each clause
    "must be evaluated by its own facts and circumstances." Grossinger
    Motorcorp, Inc. v. Am. Nat'l Bank & Trust Co., 
    607 N.E.2d 1337
    ,
    1345 (Ill. App. Ct. 1992); see Penske, 
    725 N.E.2d at 19
    .
    The Illinois cases (including federal cases applying
    Illinois law) send mixed messages about the degree of suspicion
    with       which   putative   liquidated    damages   provisions     should     be
    viewed.       On the one hand, some case law suggests that close calls
    should be resolved in favor of declaring the disputed clause to be
    a penalty.7        See, e.g., GK Dev., Inc. v. Iowa Malls Fin. Corp., 
    3 N.E.3d 804
    , 816 (Ill. App. Ct. 2013); Stride v. 120 W. Madison
    Bldg. Corp., 
    477 N.E.2d 1318
    , 1321 (Ill. App. Ct. 1985).                    On the
    other hand, the Illinois cases tend to give effect to the provision
    in the absence of fraud or unconscionable oppression.                See, e.g.,
    Zerjal v. Daech & Bauer Constr., Inc., 
    939 N.E.2d 1067
    , 1074 (Ill.
    App. Ct. 2010) ("In general, Illinois courts give effect to
    liquidated-damages        provisions   so     long    as    the   parties     have
    7
    This preference for penalties has at times been voiced by
    courts upholding liquidated damages provisions.       See, e.g.,
    JPMorgan Chase Bank, N.A. v. Asia Pulp & Paper Co., 
    707 F.3d 853
    ,
    867 (7th Cir. 2013).
    - 34 -
    'expressed their agreement in clear and explicit terms and there
    is no evidence of fraud or unconscionable oppression, a legislative
    directive to the contrary, or a special social relationship between
    the parties of a semipublic nature.'" (quoting Hartford Fire Ins.
    Co. v. Architectural Mgmt., Inc., 
    550 N.E.2d 1110
    , 1114 (Ill. App.
    Ct. 1990))); Newcastle Props., Inc. v. Shalowitz, 
    582 N.E.2d 1165
    ,
    1170 (Ill. App. Ct. 1991) (similar).    Here, however, we need not
    sort through this speckled landscape.   When all is said and done,
    the conclusion that section 3.3(b) is an enforceable liquidated
    damages provision is inescapable.
    A liquidated damages provision is enforceable as long as
    three conditions are satisfied:
    (1) the parties intended to agree in advance
    to the settlement of damages that might arise
    from a breach, (2) the amount provided as
    liquidated damages was reasonable at the time
    of contracting, bearing some relation to the
    damages which might be sustained, and (3) the
    actual damages would be uncertain in amount
    and difficult to prove.
    Dallas v. Chi. Teachers Union, 
    945 N.E.2d 1201
    , 1204 (Ill. App.
    Ct. 2011) (citing Jameson, 
    813 N.E.2d at 1130
    ).   In our judgment,
    all three of these conditions are satisfied here.
    The first and third conditions are plainly met.    As to
    the first, it is clear beyond hope of contradiction that Hancock
    and Abbott intended to agree in advance to the settlement of the
    damages that might result from a particular kind of breach.      A
    - 35 -
    reading of the Agreement as a whole leaves no doubt that the
    parties intended that section 3.3(b) would serve as the exclusive
    measure of damages in that event.        The provision evinces the
    parties' joint effort to fix a determinable sum as damages at the
    time of contracting — and that is a hallmark of a valid liquidated
    damages clause.    See Grossinger, 607 N.E.2d at 1346.
    We recognize, of course, that section 3.3(b) was not
    described in the Agreement as either a liquidated damages provision
    or a penalty provision — and it surely would have been prudent
    (and easy) for the parties to have made such a designation.     But
    even though language in the Agreement describing the nature of the
    provision would have been helpful (albeit not conclusive) in
    showing the parties' intent, the absence of any such description
    is a wash.    See Berggren v. Hill, 
    928 N.E.2d 1225
    , 1231 (Ill. App.
    Ct. 2010) (considering provision in real estate contract allowing
    seller to keep earnest money in event of breach to be liquidated
    damages provision even though term "liquidated damages" not used).
    We may infer the parties' intent from the language and
    structure of the Agreement, see Jameson, 
    813 N.E.2d at 1132-33
    ,
    and it is evident here that the parties intended section 3.3(b) to
    operate as a liquidated damages provision.     According to section
    3.2, "Hancock's sole and exclusive remedies for Abbott's failure"
    to fulfill its funding obligations "are set forth in [s]ections
    3.3 and 3.4."    Section 3.3(b), in turn, allows Hancock to recover
    - 36 -
    damages    for    Abbott's     underspending        in       accordance   with    a   set
    formula.    When parties agree to a formula to calculate a monetary
    remedy that must be paid in the event of a specific type of breach,
    the provision embodying that formula is normally intended to
    operate as a liquidated damages provision.8                     See N. Ill. Gas Co.
    v. Energy Coop., Inc., 
    461 N.E.2d 1049
    , 1055 (Ill. App. Ct. 1984).
    So it is here.
    The       third   condition   for   a    valid       liquidated      damages
    provision is also satisfied.          That condition requires that, in the
    event of a breach, actual damages (viewed as of the time of
    contracting) would be difficult to calculate and, thus, uncertain.
    See Jameson, 
    813 N.E.2d at 1132
    .           If it appeared to the parties at
    the time of contracting that actual damages would be readily
    calculable,       a    provision    stipulating          a     materially   different
    (higher) amount would be a penalty, not a liquidated damages
    provision. See Lake River Corp. v. Carborundum Co., 
    769 F.2d 1284
    ,
    1289-90 (7th Cir. 1985) (applying Illinois law); Stride, 
    477 N.E.2d at 1321
    .
    8Abbott suggests that the "intent" element is lacking because
    "[t]here is no evidence that the parties intended [section 3.3(b)]
    to apply where Hancock has not made its full $214 million
    contribution." This argument merely reprises Abbott's previously
    rejected claim that section 3.3(b) does not apply unless Hancock
    makes all four Program Payments, see supra Part II(B)-(C), and we
    need not repastinate that well-plowed soil.
    - 37 -
    Here,    it     is    nose-on-the-face      plain     that    Hancock's
    damages for any failure on Abbott's part to reach the Aggregate
    Spending      Target        would   have     been   surpassingly     difficult      to
    calculate at the time of contracting.                 The Program Compounds had
    to    clear   countless        hurdles,      including    successful       scientific
    development,      positive          clinical    testing     results,       regulatory
    approvals, navigating the shoals of competitive forces, and the
    establishment          of      profitable       marketing     and      distribution
    arrangements.     Even if things went like clockwork, the culmination
    of that process would take years.               Under these circumstances, the
    uncertainty associated with the successful development of the
    Program Compounds is manifest and heralds a similar degree of
    uncertainty about the financial returns that Hancock's investment
    was likely to yield.
    This uncertainty becomes pervasive when one considers
    that the damages from Abbott's breach of its spending obligation
    are virtually impossible to quantify in advance because section
    3.3(b) seeks to approximate not Hancock's future profits in their
    entirety but, rather, the amount by which those profits would be
    reduced if Abbott underspent.              Even with the benefit of hindsight,
    the   district    court        observed     that    the   diminution       in   profits
    attributable to Abbott's underspending is "inherently difficult to
    quantify."      Hancock III, 183 F. Supp. 3d at 321.                   Although the
    existence vel non of uncertainty must be determined with reference
    - 38 -
    to the time of contracting, the inscrutability of actual damages
    after     the   breach   reinforces     our   conclusion   that   pervasive
    uncertainty was baked into the cake from the very beginning.9            Cf.
    Karimi, 952 N.E.2d at 1288 (considering post facto actual damages
    to show uncertainty at time of contracting).
    Abbott's attempt to parry this thrust is unconvincing.
    It says that Hancock "[a]t various times . . . calculated its
    expected rates of return on the Agreement."          That is true as far
    as it goes, but it does not take Abbott very far. The two estimates
    to which it points differ substantially not only from each other
    but also from the investment's actual performance.            Incorrect and
    fluctuating     estimates   of   a    party's   anticipated    returns   are
    indications that actual damages were difficult to quantify and
    were therefore uncertain.10      See Jameson, 
    813 N.E.2d at 1133
    .
    9 The opacity of Hancock's actual damages distinguishes this
    case from Lake River, 
    769 F.2d at 1290
    , in which the Seventh
    Circuit found that a provision was "a penalty and not a liquidation
    of damages, because it is designed always to assure [the plaintiff]
    more than its actual damages." The same cannot be said of section
    3.3(b) because Hancock's actual damages are, as the district court
    found, "unknowable." Hancock III, 183 F. Supp. 3d at 321.
    10Abbott makes a separate argument that its underspending may
    not have caused "actual harm" and that "a monetary infusion would
    not have changed" the viability of the failed compounds. Whatever
    merit this argument might have in determining the reasonableness
    of a liquidated damages formula, it has no relevance to the
    uncertainty inherent in predicting, at the time of contracting,
    the damages apt to flow from Abbott's underspending.
    - 39 -
    We    conclude     that   the   uncertainty     of    actual    damages
    brings this case well within the heartland of those cases in which
    Illinois courts have found actual damages sufficiently uncertain
    to warrant the use of a liquidated damages provision.                   See, e.g.,
    Karimi, 952 N.E.2d at 1288; Jameson, 
    813 N.E.2d at 1132
    ; Penske,
    
    725 N.E.2d at 20
    ; Likens v. Inland Real Estate Corp., 
    539 N.E.2d 182
    , 185 (Ill. App. Ct. 1989). Accordingly, we hold that the third
    condition of the liquidated damages paradigm has been satisfied.
    This leaves the question of whether section 3.3(b),
    viewed from the perspective of the time of contracting, forged a
    reasonable estimate of actual damages. In answering this question,
    we start by rehearsing how actual damages would be measured at
    common law for Abbott's breach.                   Under Illinois law, a non-
    breaching party is entitled to damages sufficient "to place [him]
    in a position that he . . . would have been in had the contract
    been   performed,      [but]     not   to    provide    [him]   with   a    windfall
    recovery."    GK Dev., 3 N.E.3d at 816 (quoting Jones v. Hryn Dev.,
    Inc., 
    778 N.E.2d 245
    , 249 (Ill. App. Ct. 2002)).                  Such damages may
    include   lost      profits     as   long    as   the   plaintiff    proves       three
    elements: the plaintiff first must establish "the loss with a
    reasonable        degree   of    certainty,"       then    establish       that     the
    "defendant's wrongful act resulted in the loss," and, finally,
    establish     that     "the      profits      were      reasonably     within       the
    contemplation of [the] defendant at the time the contract was
    - 40 -
    entered into."    InsureOne Indep. Ins. Agency, LLC v. Hallberg, 
    976 N.E.2d 1014
    , 1033-34 (Ill. App. Ct. 2012) (quoting Equity Ins.
    Mgrs. of Ill., LLC v. McNichols, 
    755 N.E.2d 75
    , 80 (Ill. App. Ct.
    2001)).
    Because the asserted breach in this case consists of
    Abbott's failure to reach the Aggregate Spending Target, Hancock
    is entitled to damages reflecting the profits that it would have
    garnered if Abbott had spent the required amount.          Of course, even
    though Abbott has breached, Hancock is still entitled to its share
    of   whatever    profits   the    Program    Compounds   may   earn.   The
    possibility that revenues will be forthcoming from this source
    must be taken into account in gauging the reasonableness of the
    section 3.3(b) formula.
    To be valid and enforceable, section 3.3(b) need not
    perfectly replicate actual loss.        Instead, it must only bear some
    relation to the loss — here, the lost profits attributable to
    Abbott's underspending.          See Dallas, 
    945 N.E.2d at 1205
    .       The
    inquiry is prospective, not retrospective: we do not compare the
    amount derived by application of the liquidated damages formula to
    a post facto appraisal of the actual damages.              Rather, we ask
    whether "the amount reasonably forecasts and bears some relation
    to the parties' potential loss as determined at the time of
    contracting."    Karimi, 952 N.E.2d at 1288.
    - 41 -
    Measuring future damages inevitably entails a certain
    amount of guesswork, and we afford the parties more leeway as the
    difficulty of estimating damages increases.          See XCO Int'l, 
    369 F.3d at 1001-02
    ; see also United Order of Am. Bricklayers & Stone
    Masons Union No. 21 v. Thorleif Larsen & Son, Inc., 
    519 F.2d 331
    ,
    335 (7th Cir. 1975) (explaining that "the greater the difficulty
    of estimating the damages, the greater will have to be the latitude
    accorded   to   the   determination   of   the   reasonableness   of   the
    forecast").     This principle fits neatly with the purpose of
    liquidated damages provisions because "the case for a contractual
    specification of damages is stronger the more difficult it is to
    estimate damages."     XCO Int'l, 
    369 F.3d at 1001
    .
    The degree of uncertainty in this case is pronounced,
    and our inquiry into the enforceability of section 3.3(b) must
    take that high degree of uncertainty into account.         The question
    is not whether section 3.3(b) anticipates Hancock's actual damages
    with precision, nor even whether its formula provided the best
    possible estimate with respect to this particular breach.          Given
    the uncertainty of actual damages at the time of contracting,
    section 3.3(b) ought to be upheld unless its formula is apt to
    produce "an outlandish estimate of the damages that [the non-
    breaching party] might sustain as a result of" the breach.        
    Id. at 1003
    .
    - 42 -
    A salient feature of section 3.3(b) is that it operates
    proportionally.    Liquidated damages provisions that operate on a
    sliding scale, proportional to the magnitude of the breach, are
    favored because they indicate that the parties were attempting in
    good faith to estimate the damages likely to flow from a particular
    breach.   See 
    id. at 1004
    ; Jameson, 
    813 N.E.2d at 1133
     (upholding
    liquidated damages award that varied based on number of units).       A
    single, invariant sum for all breaches too frequently will yield
    an unrealistic estimate of actual damages for any given breach.
    See, e.g., Energy Plus Consulting, LLC v. Ill. Fuel Co., 
    371 F.3d 907
    , 909-10 (7th Cir. 2004); Checkers Eight Ltd. P'ship v. Hawkins,
    
    241 F.3d 558
    , 562 (7th Cir. 2001); GK Dev., 3 N.E.3d at 817.
    Two     simple   and   related   propositions   fortify   our
    conclusion that section 3.3(b) reasonably forecasts and bears a
    sufficient relation to Hancock's potential loss (as envisioned at
    the time of contracting).        First, it seems to us a commonsense
    proposition that, in this context, higher spending is likely to
    increase future profits.      Second, it seems equally probable that
    the amount of lost profits will be higher when the spending
    shortfall is greater.      One could reasonably have thought, at the
    time of contracting, that a larger infusion of cash by Abbott would
    make available additional resources for the development of the
    Program Compounds and, at the same time, would indicate Abbott's
    renewed commitment to the success of those compounds.      Conversely,
    - 43 -
    one could reasonably have thought, at the time of contracting,
    that a reduced investment by Abbott would shrink the resources
    available for the development of the Program Compounds and, at the
    same time, would indicate a lessened commitment to the success of
    those compounds, thus dampening Hancock's prospects for profits.
    One could of course imagine circumstances under which additional
    spending might not lead to greater profits or under which a larger
    spending shortfall might not result in higher lost profits.                            One
    or   both    of     the   sophisticated        parties      to    this       transaction
    undoubtedly        considered    such     possibilities.           Yet   we     are    not
    concerned     with      the   universe    of   potential         eventualities        but,
    rather, with reasonable assumptions about the enterprise's general
    prospects as viewed from the time of contracting.
    Section 3.3(b) builds upon these propositions.                        Under
    its formula, Hancock's damages increase proportionally to the
    magnitude     of    the   disparity       between    actual       spending      and    the
    Aggregate Spending Target.              A formula that increases Hancock's
    damages proportionally to the Aggregate Carryover Amount — as this
    formula     does    —   seems   well-calculated        to   afford       a   reasonable
    estimate of Hancock's actual damages.                 We hold, therefore, that
    this final condition of the liquidated damages paradigm is met.
    That ends this aspect of our inquiry.                  Inasmuch as all
    three   of   the     requisite    conditions        for   the     enforcement         of   a
    liquidated     damages        provision    are      satisfied,      section      3.3(b)
    - 44 -
    constitutes an enforceable liquidated damages provision.                       Abbott
    resists this determination, advancing a triumvirate of overlapping
    arguments.       Whether       viewed    singly      or   in    combination,    these
    arguments fail to persuade.
    To begin, it points out that the formula does not
    distinguish      between       shortfalls      caused     by    Hancock's      reduced
    contributions and shortfalls caused by Abbott's withholding of
    funds.     Had    Hancock      made     all   four   of   its    scheduled     Program
    Payments, the Aggregate Spending Target would have been achieved.
    Since Hancock's reduced contributions "caused" the shortfall,
    Abbott's thesis runs, a formula that nonetheless awards Hancock
    damages must unreasonably estimate damages.
    This thesis twists the language of the Agreement.                   Under
    the terms of the Agreement, it is Abbott's sole responsibility,
    set out in section 3.2, to fund "at least the Aggregate Spending
    Target during the Program Term."              Abbott's thesis implies that its
    spending obligation is capped at $400,000,000 — but the Agreement
    says no such thing.            Where, as here, Hancock is excused under
    section 3.4 from making some future payments, Abbott's minimum
    spending     obligation        climbs    proportionally         (to   points    above
    $400,000,000).     Contrary to Abbott's self-serving assertion, there
    was no need for the Agreement — either as a matter of law or as a
    matter     of    logic     —    to    "distinguish        between     underspending
    attributable to lower contributions by Hancock and underspending
    - 45 -
    caused by lower contributions by Abbott."   They are in essence one
    and the same.
    Abbott next complains that section 3.3(b), construed in
    the manner that Hancock envisions, gives Hancock a greater award
    the earlier the breach occurs (when Hancock has invested less).
    As Abbott sees it, section 3.3(b) generates a windfall for Hancock
    because Hancock is entitled to a larger award when the breach
    occurs earlier in the Program Term.     But this is not a windfall;
    it is merely a feature of how the formula is designed to work.
    The damages decrease as the spending shortfall decreases because
    section 3.3(b) is meant to estimate the impact of underspending on
    future profits.    This design makes commercial sense: as the
    spending shortfall shrinks, the adverse effect on total profits
    should be less. Thus, it is reasonable to anticipate that a breach
    by Abbott early in the Program Term (when much less has been spent
    on the development of the Program Compounds) will have a more
    deleterious effect on future profits.   If the Program Term has run
    its course (or nearly so) and the Aggregate Spending Target has
    almost been reached, the smaller shortfall presumably would have
    a less severe impact on the program's long-term profitability.11
    11 Abbott's windfall concern might be justified if Hancock
    could manipulate the Agreement and choose to forgo future Program
    Payments in order to reap an undeserved harvest under section
    3.3(b).   No such danger looms, though, because Abbott controls
    whether Hancock's duty to make all four Program Payments persists.
    This case illustrates the point: Hancock's obligation to make its
    - 46 -
    An Illinois court previously has rejected an argument
    analogous to Abbott's argument.      In Jameson, the plaintiff (a real
    estate agent) contracted with the defendant-developer for the
    exclusive right to sell the units in a condominium complex.           See
    
    813 N.E.2d at 1127
    .    The parties agreed to a damages clause, which
    stipulated that if the defendant revoked the plaintiff's sales
    authority, the plaintiff would be entitled to damages premised on
    unrealized commissions (calculated on the basis of the full price
    of unsold units).       See 
    id.
         After the defendant breached, he
    attacked the damages clause as an unenforceable penalty.               In
    support, the defendant contended that the clause amounted to a
    "tremendous windfall" because the measure of damages assumed that
    every unit would sell at the list price and that the plaintiff
    would not have to split any commissions.       
    Id. at 1133
    .
    The court disagreed, holding that the clause was a valid
    and enforceable liquidated damages clause.       See 
    id.
       It explained
    that   the   defendant's   breach   deprived   the   plaintiff   of   "the
    opportunity to sell the units" and took away "any chance" that the
    plaintiff might have had of obtaining commissions on those units.
    
    Id.
        The possibility that other factors might have reduced the
    last two Program Payments was excused only because Abbott had
    breached (that is, Abbott had made apparent that it would not do
    what was necessary to reach the Aggregate Spending Target). Seen
    in this light, Hancock's reduced contribution was the direct and
    foreseeable result of Abbott's underspending.
    - 47 -
    plaintiff's actual commissions had the defendant not breached only
    illustrated the difficulty of calculating actual damages at the
    time of contracting.      See 
    id.
    In this case, as in Jameson, the plaintiff (Hancock) was
    deprived of the opportunity for which it had bargained — the chance
    to reap the profits of a fully funded research program.              Any doubt
    about factors that might have reduced these profits only "prove
    the validity of the clause [by] show[ing] just how uncertain and
    difficult     calculating   actual      damages    was   at    the   time   of
    contracting."      
    Id.
    Abbott's last argument strikes a similar chord.                It
    submits that damages should be smaller when the breach occurs
    earlier in the Program Term because Hancock will have avoided more
    costs.   This argument taps into the principle that a non-breaching
    party's damages generally ought to be reduced by the costs that
    the party avoids as a result of the breach.           See Sterling Freight
    Lines, Inc. v. Prairie Mat'l Sales, Inc., 
    674 N.E.2d 948
    , 951 (Ill.
    App. Ct. 1996); Levan v. Richter, 
    504 N.E.2d 1373
    , 1378 (Ill. App.
    Ct. 1987).
    We   acknowledge   that,   under     Illinois    law,   Hancock's
    recovery should be based on its net lost profits, that is, the
    lost profits attributable to Abbott's underspending less Hancock's
    avoided costs.      See Sterling Freight, 674 N.E.2d at 951.          Section
    - 48 -
    3.3(b) does not make an explicit reference to avoided costs,12 but
    the absence of such a reference is not problematic: since there is
    no   sum   certain   representing   Hancock's    gross   lost    profits,
    Hancock's avoided costs cannot be subtracted from its gross lost
    profits (an unknowable figure) in a literal sense.           Rather, in
    keeping     with     section   3.3(b)'s    general       principle     of
    proportionality, the Agreement reasonably anticipates that the
    increased lost profits caused by an earlier breach will offset the
    greater avoided costs.
    Abbott posits that a breach early in the Program Term
    should engender a smaller, not a larger, liquidated damages award
    because Hancock has avoided more costs.         Yet Abbott conveniently
    overlooks the corresponding fact that the gross lost profits will
    almost certainly be higher for an earlier breach.               Thus, the
    increased avoided costs are deducted from a larger gross profits
    number, resulting in higher damages.
    12 Section 3.3(b)'s silence regarding avoided costs does not
    necessarily mean that avoided costs are not factored into section
    3.3(b)'s formula. Section 3.2 states that if Abbott "fail[s] to
    fund the Research Program in accordance with this [s]ection,"
    Hancock's "sole and exclusive remedies" are "set forth in
    [s]ections 3.3 and 3.4."    Inasmuch as the parties provided for
    both liquidated damages and the discharge of Hancock's future
    payment obligations, we may safely assume that they considered
    avoided costs in crafting section 3.3(b). Of course, we must still
    ask — as we have done supra — whether their estimate of damages in
    section 3.3(b) is reasonable.
    - 49 -
    As a counterpoint, consider a situation in which Abbott
    breaches late in the Program Term.       Hancock may have less (or even
    no) avoided costs, but its lost profits will also be less.                It
    follows that liquidated damages in such a case should be less even
    though Hancock's avoided costs are less.
    There is an interrelated reason why it is logical that
    the liquidated damages would be greater when Hancock's avoided
    costs are greater.        But for Abbott's breach (which triggered
    section 3.4), Hancock would have contributed more funds to the
    development of the Program Compounds. These additional funds would
    have spurred the development of the Program Compounds and likely
    would have increased their profitability. So, when Abbott breaches
    before Hancock has made all four of its Program Payments, Abbott
    doubly suppresses future profits: first, by underfunding its own
    obligations, and second, by shutting off the spigot so that
    additional funds from Hancock dry up.
    The   formula    set   out   in   section   3.3(b)   may   be   an
    unorthodox way of accounting for avoided costs, but it is tailored
    to suit the idiosyncratic nature of the parties' relationship.
    Normally, avoided costs are a one-way ratchet. Take, for instance,
    a typical case.    X, who has a factory in Massachusetts, enters
    into a contract with Y to manufacture and deliver widgets F.O.B.
    at Y's warehouse in Illinois.          After the widgets are made but
    before they are shipped, Y notifies X that it will not honor the
    - 50 -
    contract.     When X sues for damages, the costs of transportation
    are avoided costs, that is, they are costs that X will not have to
    incur and, thus, they count, dollar for dollar, against what would
    otherwise have been X's damages.
    Here, however, Hancock's lessened contributions are a
    different species of avoided costs: they are a two-way ratchet.
    While it is true that Hancock's costs are diminished by the fact
    that it is excused from making its third and fourth Program
    Payments, the diminished funding that results from that non-
    payment also diminishes Hancock's anticipated profits.           After all,
    it is a reasonable assumption that the more money that is made
    available for the development of the Program Compounds, the greater
    the anticipated profits will be.          Given the deference that we owe
    the parties' negotiated formula for estimating damages that are
    highly uncertain, see XCO Int'l, 
    369 F.3d at 1001-02
    , and the
    unique nature of the avoided costs at issue here, we do not think
    that we are at liberty to substitute our judgment for that of the
    contracting parties.
    To sum up, the lost profits attributable to Abbott's
    underspending in the wildly speculative business of developing
    pharmaceutical      drugs    were    uncertain    and   defied   meaningful
    calculation    at   the     time    of   contracting.    Recognizing   this
    difficulty and intending to address it, Abbott and Hancock agreed
    to the formula contained in section 3.3(b) to provide a reasonable
    - 51 -
    estimate of damages in the event of a breach by Abbott of its
    spending obligation.     We are confident that, on balance, section
    3.3(b)'s   formulaic   estimate      of     those    actual   damages    falls
    comfortably within the universe of reasonable estimates.                  See
    Inland Bank, 
    927 N.E.2d at 783
    .       Abbott has not carried its burden
    of proving that section 3.3(b) is a penalty rather than a valid
    and enforceable liquidated damages provision, see XCO Int'l, 
    369 F.3d at 1003
    , and it must pay Hancock one-third of the Aggregate
    Carryover Amount as liquidated damages.          According to the district
    court's calculations, which we see no need to revisit, that amount
    is $33,033,333.33.
    E.   Rescission.
    We need not linger long over Hancock's contention that
    the district court erred in striking its prayer for rescission.
    The doctrine of election of remedies prevents a party from seeking
    inconsistent remedies.
    Applying    this    doctrine      leads     inexorably   to     the
    conclusion that a party may not both rescind a contract and recover
    damages for a breach of that contract.                See Harris v. Manor
    Healthcare Corp., 
    489 N.E.2d 1374
    , 1381 (Ill. 1986).                     Those
    remedies are flatly inconsistent with each other: rescission is in
    essence a disavowal of the contract whereas recovery for a breach
    is in essence an affirmance of the contract. See Newton v. Aitken,
    
    633 N.E.2d 213
    , 216 (Ill. App. Ct. 1994).               To both rescind an
    - 52 -
    agreement and recover damages for a breach of that agreement would
    therefore be "inappropriate."     
    Id. at 217
    .     As a result, "[t]he
    election of either remedy is an abandonment of the other."        
    Id.
    Here, Hancock has recovered damages under section 3.3(b)
    for Abbott's breach of section 3.2.          Enforcing section 3.3(b)
    implies an affirmance of the Agreement and, thus, is inconsistent
    with any right to rescission.13     Given this inescapable logic, we
    hold that Hancock may not now seek rescission of the Agreement.
    See Harris, 
    489 N.E.2d at 1381
    .     Consequently, the district court
    did not err in striking Hancock's prayer for rescission.
    F.    Prejudgment Interest.
    In a diversity action, state law controls a prevailing
    party's entitlement to prejudgment interest.           See Comm'l Union
    Ins. Co. v. Walbrook Ins. Co., 
    41 F.3d 764
    , 774 (1st Cir. 1994).
    Conversely,   federal    law   governs   a   party's    entitlement     to
    postjudgment interest.    See Vázquez-Filippetti v. Cooperativa de
    Seguros Múltiples de P.R., 
    723 F.3d 24
    , 28 (1st Cir. 2013); see
    also 
    28 U.S.C. § 1961
     (providing for postjudgment interest on civil
    judgments in federal courts).
    13 The district court held that Hancock's pursuit of a
    declaratory judgment in Hancock I and Hancock II was inconsistent
    with Hancock's prayer for rescission.    See Hancock III, 183 F.
    Supp. 3d at 302-03. That may be so, but we have no need to pursue
    the point.
    - 53 -
    Under Illinois law, "[p]rejudgment interest is proper
    when it is authorized by a statute, authorized by agreement of the
    parties, or warranted by equitable considerations." In re Marriage
    of O'Malley ex rel. Godfrey, 
    64 N.E.3d 729
    , 746 (Ill. App. Ct.
    2016).   Here, Hancock is entitled to prejudgment interest both by
    statute, see 815 Ill. Comp. Stat. 205/2, and by the terms of the
    Agreement, specifically section 9.3.          As a practical matter, the
    only difference between the prejudgment interest contemplated by
    the Illinois statute and that available under the Agreement is the
    rate.    The statutory rate is 5%.          See 
    id.
       The rate under the
    Agreement is the lesser of "the prime rate of interest plus two
    hundred (200) basis points" or "the highest rate permitted by
    applicable law."
    When   a   prevailing   party    is   entitled   to   prejudgment
    interest both under a statute and under a contractual provision,
    the prevailing party may recover prejudgment interest at the higher
    available rate.       See Mich. Ave. Nat'l Bank v. Evans, Inc., 
    531 N.E.2d 872
    , 881 (Ill. App. Ct. 1988).            On remand, the district
    court should calculate prejudgment interest either pursuant to the
    statute or pursuant to the Agreement (as Hancock may elect).
    With respect to duration, "the beginning date for the
    accrual of postjudgment interest marks the ending date for the
    accrual of prejudgment interest."          Old Second Nat'l Bank v. Ind.
    Ins. Co., 
    29 N.E.3d 1168
    , 1180 (Ill. App. Ct. 2015).             To determine
    - 54 -
    that date, the weight of authority in diversity cases holds that
    federal   law   establishes   when   postjudgment    interest   begins   to
    accrue and, thus, establishes when prejudgment interest ceases to
    accrue.    See Art Midwest, Inc. v. Clapper, 
    805 F.3d 611
    , 615 (5th
    Cir. 2015); Coal Res., Inc. v. Gulf & W. Indus., Inc.,

    Republic W. Ins. Co., 
    147 F.3d 25
    , 29-30 (1st Cir. 1998) (applying
    Federal Rules of Civil Procedure and 
    28 U.S.C. § 1961
     to determine
    date that postjudgment interest would begin to accrue in diversity
    suit).    But cf. Tobin v. Liberty Mut. Ins. Co., 
    553 F.3d 121
    , 146-
    47 (1st Cir. 2009) (suggesting different rule in non-diversity
    case).
    Under federal law, "where a first judgment lacks an
    evidentiary or legal basis, post-judgment interest accrues from
    the date of the second judgment."      Cordero v. De Jesus-Mendez, 
    922 F.2d 11
    , 16 (1st Cir. 1990). Because the district court's decision
    interpreting section 3.3(b) is entirely reversed, that portion of
    its judgment perforce lacked a legal basis.         On remand, therefore,
    the district court should calculate prejudgment interest on this
    award beginning from the date that it was due under the Agreement
    - 55 -
    (thirty days after the end of 2005) and continuing until the date
    that the district court enters its amended judgment.              Postjudgment
    interest will accrue from that date forward. See 
    28 U.S.C. § 1961
    ;
    Kaiser Alum. & Chem. Corp. v. Bonjorno, 
    494 U.S. 827
    , 836 (1990).
    The   portion    of   the    district      court's   judgment    that
    awarded Hancock damages for Abbott's breach of the Agreement's
    audit provision in the amount of $198,731 was not appealed and
    remains in effect.          If that portion of the judgment remains
    unsatisfied, it must be incorporated in the amended judgment,
    together with prejudgment interest to the date of the original
    judgment    (as   previously      calculated      by   the   district   court).
    Postjudgment interest shall continue to accrue on that portion of
    the judgment from that date forward.
    III.   CONCLUSION
    Refined to bare essence, this is a case about keeping
    promises.    Hancock and Abbott made promises to each other.            Abbott
    nonetheless    failed   to   honor      several    promises,     including   one
    important promise in particular.             The parties had provided a
    damages remedy for just such an eventuality, and that remedy
    produced a rational estimate of Hancock's actual damages which, at
    the time of contracting, were highly uncertain and impossible to
    calculate.    The remedy is, therefore, a valid liquidated damages
    clause, and Hancock is entitled to enforce it according to its
    tenor.

    We need go no further. For the reasons elucidated above,
    we reverse the judgment of the district court with respect to
    section 3.3(b) of the Agreement, affirm its dismissal of Hancock's
    prayer     for   rescission,   and     remand   for   further   proceedings
    consistent with this opinion.          Costs shall be taxed in favor of
    Hancock.
    So Ordered.
