    ARGUED SEPTEMBER 17, 2007—DECIDED APRIL 11, 2008
    ____________
    Before FLAUM, RIPPLE and WOOD, Circuit Judges.
    RIPPLE, Circuit Judge. Sompo Japan Insurance, Inc.
    (“Sompo”), as an insurer subrogated to the rights of
    Hitachi Data Systems Corporation (“HDS”), brought this
    action against Yusen Air and Sea Service Company
    (“Yusen”), Nippon Cargo Airlines (“NCA”) and Pace Air
    2                                        Nos. 06-3942 & 06-4032
    Freight (“Pace”). It sought compensation for damage to
    computer equipment that the defendants transported from
    Japan to HDS’s Indiana facility.1 Sompo settled its claims
    with Yusen and Pace, but NCA proceeded to trial. After a
    bench trial, the district court entered judgment against
    NCA in the amount of $74,450.84 plus costs. NCA then
    timely filed this appeal, and Sompo timely filed a cross
    appeal that challenged the district court’s denial of pre-
    judgment interest. For the reasons set forth in this opin-
    ion, we affirm the judgment of the district court.2
    I
    BACKGROUND
    HDS purchased a number of computer parts from its
    manufacturer in Japan. HDS hired Yusen to arrange for
    their transportation from Tokyo to its facility in Indiana.
    Yusen contracted with NCA to transport the parts by air
    from Tokyo to Chicago’s O’Hare Airport. HDS separately
    retained Pace to transport the goods from O’Hare to
    Indiana by truck.
    On December 28, 2000, a portion of the shipment was
    damaged while the goods were in the process of being
    transferred from the loading dock to Pace’s trucks at
    NCA’s cargo facility at O’Hare. The undisputed value of
    the damaged cargo was at least $271,304. Sompo, a
    subrogated insurer, paid the insurance proceeds to HDS
    and commenced litigation against Pace, Yusen and NCA.

    Before trial, however, Sompo settled its claims against
    Pace and Yusen for $100,000 and $8,500, respectively.
    Sompo then moved for summary judgment against NCA,
    seeking recovery under the Warsaw Convention and
    Montreal Protocol No. 4. The Warsaw Convention estab-
    lishes a ceiling on damages recoverable against an airline,
    limiting NCA’s potential liability to 17 Special Draw-
    ing Rights (“SDRs”)3 per kilogram, or approximately
    $74,450.84. NCA cross-moved for summary judgment;
    it sought a setoff of the $108,500 Sompo had received
    in settlements against the limited damages allowable
    under the Warsaw Convention. Such a setoff, taken from
    the limited liability amount, would reduce any potential
    judgment against NCA to $0.
    The district court initially granted Sompo’s motion
    for summary judgment, denied NCA’s motion for sum-
    mary judgment and entered judgment against NCA for
    $76,923.03. After NCA moved to amend the judgment
    under Federal Rule of Civil Procedure 59(e), the district
    court vacated the judgment. It conducted a bench trial
    and returned a verdict in favor of Sompo. It held that
    NCA was entitled to a setoff of the settlement amounts
    under Illinois law, but the court nevertheless refused
    NCA’s motion to apply the setoff against the limited
    liability amount established in the Warsaw Convention.

    A Special Drawing Right (“SDR”) is an artificial currency,
    established by a “basket” of global currencies (the U.S. dollar,
    the euro, the Japanese yen and the British pound), and pub-
    lished daily by the International Monetary Fund. The value of
    an SDR fluctuates based on the global currency market, and,
    under Article 22(6), it is determined “at the date of the judg-
    ment.”

    Rather, it applied the $108,500 setoff against Sompo’s total
    proven damages, $271,304, reducing that amount to
    $167,114. The district court then entered judgment against
    NCA in the amount of $74,450.84 plus costs, the maxi-
    mum amount allowable under the Warsaw Convention’s
    liability cap at the time of the judgment.
    NCA now seeks review of the district court’s decision
    to apply the setoff against the total amount of proven
    damages rather than its limited liability amount. Sompo
    cross-appeals the court’s denial of prejudgment interest.
    A. The Warsaw Convention—History and Purpose
    The Warsaw Convention4 was the product of two inter-
    national conferences that occurred between 1925 and
    1929, while the airline industry was in its infancy. The
    Convention, largely a response to fears of airline carrier
    bankruptcy, had two primary goals: (1) to establish unifor-
    mity in the aviation industry regarding the procedural
    and substantive law applicable to claims arising out of
    international air travel; and (2) to limit air carriers’ poten-
    tial liability in the event of an accident.5

    The Warsaw Convention set out a scheme for limiting
    an air carrier’s liability. It established a presumption of
    liability against the air carrier for accidents arising out of
    international air travel. Warsaw Convention, arts. 17-19.
    Potential plaintiffs received the benefit of presumptive
    liability against the carrier, but they also were subject to
    certain affirmative defenses and a strict damages
    ceiling. 
    Id.,
     arts. 20-22. The original Convention set the
    liability cap at $8,500 for personal injury and approxi-
    mately $20 per kilogram for damage to goods, thus protect-
    ing the airlines from the risk of catastrophic damages.
    
    Id.,
     art. 22.
    As the fledgling airline industry matured, it became
    clear that the liability limitations of the Warsaw Con-
    vention were far too low. Largely at the insistence of the
    United States, the Warsaw Convention signatories recon-
    vened in 1955 at the Hague to amend the Convention. See
    Paul Dempsey & Michael Milde, International Air Carrier
    Liability: The Montreal Convention of 1999, at 17 (2005).
    Among other alterations, the Hague Protocol increased
    the liability cap to approximately $16,500 for personal
    injuries. Id. at 20. The United States ultimately refused to
    ratify the Hague Protocol, in part because it saw the
    amended liability cap as still too low. Id. at 20-21.
    Recognizing the harsh results of the unamended Warsaw
    Convention for potential plaintiffs, in 1965 the United
    States gave notice of its denunciation of the Convention. Id.
    at 29. Shortly before the denunciation was to take
    effect, however, a large number of private air carriers
    entered into an interim agreement, in which they volun-
    tarily increased their personal injury liability limitation
    to $75,000. This voluntary action by the airlines became
    6                                     Nos. 06-3942 & 06-4032
    known as the Montreal Agreement.6 Consequently, the
    United States’ denunciation was withdrawn.
    Efforts to modernize the Convention continued, and a
    number of different amendments, most notably the Mon-
    treal Protocols, were developed to address formally
    concerns about under-compensation for plaintiffs. In
    1998, the United States ratified Montreal Protocol No. 4
    (“MP4”),7 which raised the liability cap for damage to
    cargo to 17 SDRs per kilogram. At the time of ratification,
    this equaled approximately $25 per kilogram. Id. at 28. The
    MP4 went into effect in the United States on March 4, 1999.
    Prior to 2003, then, a complex interplay of conventions,
    treaties and domestic laws governed international air
    carrier liability. See Dempsey & Milde, supra, at 1-2. The
    Montreal Convention8 (not to be confused with the MP4
    or Montreal Agreement) was the product of a United
    Nations effort to reform the Warsaw Convention “so as to
    harmonize the hodgepodge of supplementary amend-
    ments and intercarrier agreements of which the Warsaw

    Convention system of liability consists.” Erlich v. American
    Airlines, Inc., 
    360 F.3d 366
    , 371 n.4 (2d Cir. 2004). In
    May 1999, representatives of 121 nations gathered in
    Montreal, Canada to negotiate and adopt a new treaty
    that would replace the Warsaw Convention. 
    Id.
     At the
    end of a three-week conference, the delegates approved
    the Montreal Convention, and fifty-two countries, includ-
    ing the United States, immediately signed the treaty.
    
    Id.
     The new treaty “unifies and replaces the system of
    liability that derives from the Warsaw Convention,” 
    id.,
    explicitly recognizing “the importance of ensuring pro-
    tection of the interests of consumers in international
    carriage by air and the need for equitable compensation
    based on the principle of restitution.” Montreal Conven-
    tion, pmbl. It establishes strict liability for personal injury
    claims up to 100,000 SDRs, and presumptive liability
    without limit above that amount. Montreal Convention,
    art. 21. This Convention seems to have reversed one of
    the premises of the original Warsaw Convention, which
    favored the airlines at the expense of consumers. Erlich,
    
    360 F.3d at
    371 n.4. Nevertheless, the Montreal Convention
    did not alter the original Warsaw Convention goal of
    maintaining limited and predictable damage amounts
    for airlines. The United States Senate ratified the treaty
    on July 31, 2003, and it entered into force on September 5,
    2003.
    In this case, the incident giving rise to Sompo’s claim
    took place on December 28, 2000—after the ratification
    of MP4 but several years before the Montreal Convention
    became effective in the United States. Therefore, NCA’s
    liability here is governed by the Warsaw Convention as
    amended by the MP4, not by the new Montreal Conven-
    tion. Under Article 18 of the Warsaw Convention, NCA
    8                                   Nos. 06-3942 & 06-4032
    is presumptively liable for any damage sustained to
    goods while they are in the airline’s custody. Under Article
    22(2), however, NCA’s potential liability is limited to 17
    SDRs per kilogram of damaged goods, or approximately
    $74,450.84 in this case.
    B. NCA’s Right to a Setoff
    1.
    Before trial, Sompo settled its claims against both Pace
    and Yusen for $100,000 and $8,500, respectively. NCA
    claims that it is entitled to a “setoff”—or, more precisely,
    a reduction in the judgment amount—to the extent of
    these settlement amounts. The district court held that a
    setoff was appropriate under the Illinois Joint Tortfeasors
    Contribution Act (“JTCA”), 740 Ill. Comp. Stat. 100/2(c).
    We review such conclusions of law de novo. Johnson v.
    West, 
    218 F.3d 725
    , 729 (7th Cir. 2000).
    Relying on El Al Israel Airlines, Ltd. v. Tsui Yuan Tseng,
    
    525 U.S. 155
    , 175 (1999), Sompo contends that the Warsaw
    Convention generally preempts any domestic contribution
    or setoff laws. El Al indeed stands for the proposition
    that the Warsaw Convention preempts local law causes
    of action to the extent that they are inconsistent with the
    Convention. El Al, 
    525 U.S. at 161, 175
    . However, the
    Convention’s preemption is not complete: “auxiliary
    issues” not addressed by the Convention, such as who
    may recover and for what harms they may be compen-
    sated, are left to domestic law. 
    Id. at 169-70
    ; Zicherman v.
    Korean Air Lines Co., 
    516 U.S. 217
    , 225 (1996) (holding that
    the question of whether loss of society damages may be
    recovered under the Warsaw Convention is an issue
    governed by domestic law). An air carrier’s right to a
    Nos. 06-3942 & 06-4032                                      9
    setoff or contribution from a joint tortfeasor is, similarly,
    incidental to the causes of action available under the
    Convention and therefore not subject to its limited preemp-
    tion.
    Sompo further submits that the Convention contains its
    own setoff provision, which specifically preempts other
    domestic setoff or contribution laws. Article 25A states:
    1. If an action is brought against a servant or agent of
    the carrier arising out of damage to which this Conven-
    tion relates, such servant or agent, if he proves that he
    acted within the scope of his employment, shall be
    entitled to avail himself of the limits of liability
    which that carrier himself is entitled to invoke under
    Article 22.
    2. The aggregate of the amounts recoverable from the
    carrier, his servants and agents, in that case, shall not
    exceed the said limits.
    Warsaw Convention as amended by MP4, art. 25A(1), (2).
    In Sompo’s view, because Article 25A effectively allows an
    air carrier a setoff against its limitation amount for any
    payments made by its servants or agents, setoffs not
    mentioned in the provision, such as setoffs against co-
    defendants who are not such servants or agents, are not
    permitted. Consequently, Sompo argues, NCA cannot
    seek a setoff because Article 25A would not allow such
    a setoff.
    Article 25A simply is not a provision designed to deal
    with joint and several liability. It addresses whether an
    airline may effectively be held liable for damages above
    the Convention’s liability cap because of judgments
    against its agents. See, e.g., Reed v. Wiser, 
    555 F.2d 1079
    ,
    1083-97 (2d Cir. 1997) (examining the history of the MP4
    10                                  Nos. 06-3942 & 06-4032
    and noting that the purpose of Article 25A was to prevent
    an end run around the liability limits in the Convention).
    Article 25A fulfills the purpose of the Convention by
    precluding suits against agents that could increase effec-
    tively the liability of the airlines. Joint tortfeasors,
    whose money flows from different sources, are not the
    concern of Article 25A.
    Cases about preemption, such as El Al, note the intent
    of the Convention’s framers to create a uniform scheme
    of regulation for international air carriers. The Conven-
    tion’s concern with uniformity focuses on protecting
    the airlines from catastrophic judgments and ensuring
    them predictability in liability. El Al, 
    525 U.S. at 157
    (“Given the Convention’s comprehensive scheme of
    liability rules and its textual emphasis on uniformity,
    the Court would be hard put to conclude that the Warsaw
    delegates meant to subject air carriers to the distinct,
    nonuniform liability rules of the individual signatory
    nations.”). The Convention precludes both state causes
    of action and suits against agents because of their poten-
    tial to erode the effectiveness of the treaty’s liability
    limitations. The airline’s relationship to joint tortfeasors
    is merely an “auxiliary issue,” however, and uniformity
    in this context is, under the scheme of the Convention,
    less important.
    The Convention also contains a savings clause which
    specifically notes that “[n]othing in this Convention
    shall prejudice the question whether a person liable for
    damage in accordance with its provisions has a right of
    recourse against any other person.” Warsaw Convention,
    art. 30A. Thus, it appears that the Convention refused
    explicitly to preempt local contribution schemes. Further-
    more, preemption of state laws by treaty is generally
    disfavored. El Al, 
    525 U.S. at 181
     (Stevens, J. dissenting)
    Nos. 06-3942 & 06-4032                                   11
    (“[A] treaty, like an Act of Congress, should not be con-
    strued to preempt state law unless its intent to do is
    clear.”); Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 485 (1996).
    Absent clear evidence of preemption, then, we decline
    to rule that state setoff and contribution laws are pre-
    empted by the Warsaw Convention.
    2.
    Having determined that the Warsaw Convention does
    not, by its own terms, address the issue, we must look to
    the law that would govern the parties’ setoff and con-
    tribution rights absent the Convention. Zicherman v. Korean
    Air Lines Co., Ltd., 
    516 U.S. 217
    , 229 (1996). Both parties
    agree that, in the absence of the Convention, their dispute
    would be governed by Illinois law; therefore, we turn to
    an examination of Illinois law regarding contribution
    and setoffs.
    NCA claims a right of setoff under the Illinois Joint
    Tortfeasor Contribution Act (“JTCA” or “Contribution
    Act”), 740 Ill. Comp. Stat. 100/2(c). The JTCA provides in
    pertinent part:
    When a release . . . is given in good faith to one or
    more persons liable in tort arising out of the same
    injury . . . it reduces the recovery on any claim
    against the others to the extent of any amount stated
    in the release . . . or in the amount of the consider-
    ation actually paid for it, whichever is greater.
    
    Id.
     The setoff is applied “even if the resultant judgment is
    thereby reduced to zero dollars.” Pasquale v. Speed Prods.
    Eng’g, 
    654 N.E.2d 1365
    , 1382 (Ill. 1995). In order for the
    JTCA to be applicable, however, both NCA and Pace must
    12                                        Nos. 06-3942 & 06-4032
    have been “liable in tort” for the “same injury.” 740 Ill.
    Comp. Stat. 100/2(c). Both parties concede that the plain-
    tiff here suffered a single, indivisible injury to its goods.
    Their disagreement lies in whether both parties were
    “liable in tort” for the purposes of the JTCA.
    The purpose of the Contribution Act is to balance the
    equities between all culpable parties while ensuring that
    plaintiffs do not receive double recovery. Doyle v. Rhodes,
    
    461 N.E.2d 382
    , 388 (Ill. 1984); Pasquale, 
    654 N.E.2d at
    1381-
    82. In furtherance of this purpose, the Supreme Court of
    Illinois has construed “liability in tort” to mean “potential”
    tort liability, Doyle, 
    461 N.E.2d at 387
    , and the Illinois
    courts have construed broadly this “potential liability”
    criterion.9 Illinois courts determine potential tort liability
    “at the time of the injury to the plaintiff,” not when the
    9
    See, e.g., Giordano v. Morgan, 
    554 N.E.2d 810
    , 814 (Ill. App.
    Ct. 1990) (holding that the JTCA is applicable in a contracts
    case); Joe & Dan Int’l Corp. v. U.S. Fid. & Guar. Co., 
    533 N.E.2d 912
    , 918 (Ill. App. Ct. 1988) (noting that potential liability in tort
    is determined at the time of injury, not at the time of the law-
    suit, and the JTCA applies even when the plaintiff has sued in
    contract); Cirilo’s, Inc. v. Gleeson, Sklar & Sawyers, 
    507 N.E.2d 81
    , 83 (Ill. App. Ct. 1987) (same). The Illinois courts recognize
    that most other jurisdictions do not follow such a strict prefer-
    ence for contribution. Kotecki v. Cyclops Welding Corp., 
    585 N.E.2d 1023
    , 1027 (Ill. 1991). Nevertheless, they find that their
    state legislature has an especially strong preference for con-
    tribution, and thus they interpret their state’s Contribution Act
    quite liberally. 
    Id. at 1027-28
    . As noted above, the Illinois
    courts have examined and reexamined Doyle, and they main-
    tain that affirmative defenses, even if they lead to ultimate
    preemption of state law causes of action, do not negate poten-
    tial liability in tort.
    Nos. 06-3942 & 06-4032                                           13
    basis for liability is actually decided by the court. Joe &
    Dan Int’l Corp. v. U.S. Fid. & Guar. Co., 
    533 N.E.2d 912
    ,
    918 (Ill. App. Ct. 1988). The JTCA “focuses, as it was
    intended to do, on the culpability of the parties rather
    than on the precise legal means by which the plaintiff is
    ultimately able to make each defendant compensate him
    for his loss.” Doyle, 
    461 N.E.2d at 388
    .
    Sompo contends that the Illinois statute is inapplicable
    here because neither Pace nor NCA10 was potentially
    liable in tort: Sompo’s complaint included claims against
    NCA and Pace under the Warsaw Convention and the
    Carmack Amendment, both of which provide their own
    cause of action. In support of its contention, Sompo notes
    that Illinois courts have looked to the pleadings to deter-
    mine whether a party is potentially liable in tort.11 Al-
    though a party’s complaint is relevant, Illinois courts
    consistently have held that the plaintiff’s own theory
    of liability is not conclusive for the purposes of the Con-
    tribution Act.12 Furthermore, even if its pleadings were
    10
    Sompo does not dispute that Yusen, the other party to this
    litigation that entered into a settlement agreement with
    Sompo, was potentially liable in tort.
    11
    See, e.g., Ill. ex rel. Hartigan v. Cmty. Hosp. of Evanston, 
    545 N.E.2d 226
    , 230 (Ill. App. Ct. 1989) (noting that the pleadings
    alleged only a breach of fiduciary duty, not tort claims,
    and concluding that the defendant therefore was not entitled
    to contribution under the JTCA).
    12
    See, e.g., Giordano, 
    554 N.E.2d at 814
     (maintaining that “the
    theory under which the plaintiff sued the defendants was not
    dispositive as to whether both might be subject to liability in tort
    to plaintiff for the same injury for purposes of contribution
    (continued...)

    considered dispositive, that fact would not help Sompo
    here. Sompo brought claims against NCA and Pace under
    the Warsaw Convention and the Carmack Amendment; it
    also, however, chose to include negligence claims against
    NCA and Yusen in its original complaint and against
    Pace in its amended complaint. Under Sompo’s own
    theory of liability, then, the defendants were potentially
    liable in tort.
    Sompo next submits that NCA in fact never was poten-
    tially liable in tort because its claim arose under the
    Warsaw Convention, a federal liability scheme that has
    been held to preempt state tort claims in cases involving
    interstate carriers and a loss of goods. See El Al, 
    525 U.S. at 175
    . In its view, NCA likely could have defeated a state
    law negligence claim by arguing that the Warsaw Con-
    vention provides the exclusive grounds for recovery
    against it. 
    Id.
     Therefore, Sompo argues, NCA was not a
    potential tortfeasor for the purposes of the JTCA.
    The logic of the Supreme Court of Illinois, expressed
    in Doyle, 
    461 N.E.2d 382
    , is helpful to our analysis. In
    Doyle, the defendant employer maintained that its stat-
    utory immunity under the Illinois Workers’ Compensa-
    tion Act also immunized it from a contribution claim
    under the JTCA; because the state Workers’ Compensa-
    tion Act preempted other state law tort claims, the em-
    ployer maintained that it had no potential liability in tort.

    between them”); Joe & Dan, 
    533 N.E.2d at 918
     (noting that
    potential liability in tort is determined at the time of injury,
    not at the time of the lawsuit); Cirilo’s, 
    507 N.E.2d at 83

    that the Contribution Act applied even when the liability
    arose out of contract claims rather than tort claims).
    Nos. 06-3942 & 06-4032                                               15
    Id. at 384. The court rejected this argument, concluding
    that the defendant was potentially liable in tort at the time
    of the incident, even though any common law tort action
    ultimately would have been preempted by the workers’
    compensation regime. Id. at 388. It reasoned that, although
    preemption is a defense to any tort action brought by
    an employee for a work-related incident, it is merely an
    affirmative defense, not an outright bar to liability. Id. at
    386-87. In its view, an employer could make the strategic
    decision to defend against an employee’s tort claim on its
    merits rather than invoke the protections of the workers’
    compensation scheme, perhaps in the hopes that the
    jury would find the evidence of negligence lacking. In
    such a case, the employer’s legal exposure would be
    based on liability in tort. Id. Such “potential liability” was
    enough for the Supreme Court of Illinois to find the
    JTCA applicable. Id.13
    The reasoning in Doyle may be applied in this case. As
    we noted earlier, the Warsaw Convention preempts
    state tort laws to the extent that those state rules con-
    flict with its own regulatory structure. See El Al, 
    525 U.S. at 175

    still potentially liable in tort); Geise v. Phoenix Co. of Chicago, Inc.,

    The treaty precludes passengers from bringing actions
    under local law when they cannot establish air carrier
    liability under the treaty.”). However, this preemption is
    limited. Article 24 provides: “In the carriage of cargo, any
    action for damages, however founded, whether under
    this Convention or in contract or in tort or otherwise, can
    only be brought subject to the conditions and limits of
    liability set out in this Convention . . . .” (emphasis added).
    Article 24 expressly contemplates that an action may be
    brought in contract or in tort. The liability limitation
    provisions of the Warsaw Convention simply operate as
    an affirmative defense.14 Accordingly, the Supreme Court
    of Illinois’ reasoning in Doyle suggests that the limited
    preemption in the Warsaw Convention does not pre-
    clude the application of the JTCA here.
    Although the parties do not reference it, we acknowl-
    edge that we previously have held that the JTCA did not
    apply to a party sued under the Carmack Amend-
    ment because the federal statute “preempt[ed] the field
    formerly occupied by common law theories of liability.”
    N. American Van Lines v. Pinkerton Sec. Sys., 
    89 F.3d 452
    ,
    458 (7th Cir. 1996). Nevertheless, we found that decision to
    be consistent with the Illinois Supreme Court’s analysis in
    Doyle because, in North American, liability could be pre-
    mised solely on the Carmack Amendment. The plaintiff
    14
    See, e.g., Craddock Intern. Inc. v. W.K.P. Wilson & Son, Inc., 
    116 F.3d 1095
    , 1105-06 (5th Cir. 1997) (noting that the liability
    limitations in the Warsaw Convention must be pleaded as
    an affirmative defense); Distribuidora Dimsa v. Linea Aerea Del
    Cobre S.A., 
    976 F.2d 90
    , 93 (2d Cir. 1992) (referring to the liabil-
    ity limitations in the Warsaw Convention as an affirmative
    defense).
    Nos. 06-3942 & 06-4032                                     17
    there “was foreclosed from suing in tort by the terms of
    the Carmack Amendment, which preempts the field
    formerly occupied by common law theories of liability.” Id.
    at 458. Accordingly, there was no need for the defendant
    to plead the liability limitations in the Carmack Amend-
    ment as an affirmative defense: “the contract defined
    both its liability and [the plaintiffs’] right to relief.” Id.
    at 459.
    Notably, we emphasized in North American that the
    Carmack Amendment was unique. Id. at 458. It was
    intended by Congress to be a consumer-friendly law,
    establishing its own mechanism for contribution and
    “relieving shippers of the burden of determining which of
    the several carriers handling interstate shipments bears
    the blame for loss or damage under diverse state laws.” Id.
    at 457. The Warsaw Convention, on the other hand,
    privileges the air carrier and provides it with a partial
    affirmative defense to claims by potential plaintiffs. Unlike
    the Carmack Amendment, the Warsaw Convention does
    not have its own apportionment system, and it expressly
    contemplates the use of state law to fill in the interstices.
    See Warsaw Convention, art. 24 (“[A]ny action for dam-
    ages, however founded, whether under this Convention
    or in contract or in tort or otherwise, can only be brought
    subject to the conditions and limits of liability set out in
    this Convention without prejudice to the question as to
    who are the persons who have the right to bring suit and
    what are their respective rights.”); art. 30A (“Nothing
    in this Convention shall prejudice the question whether
    a person liable for damage in accordance with its provi-
    sions has a right of recourse against any other person.”).
    The Warsaw Convention therefore is particularly suited
    to the application of state setoff and contribution schemes.
    18                                   Nos. 06-3942 & 06-4032
    Accordingly, the Carmack Amendment and the Warsaw
    Convention are distinguishable, and our application of
    Doyle here is consistent with our prior opinion in North
    American.
    Furthermore, the two other circuit courts that have
    addressed the question have concluded that a right of
    setoff or contribution is available for the airlines in claims
    arising under the Warsaw Convention. See In re Air
    Crash at Little Rock, Arkansas on June 1, 1999, 
    291 F.3d 503
    ,
    516-17 (8th Cir. 2002) (examining the question of tortfeasor
    contribution under the Warsaw Convention, and directing
    the district court to allow the defendant airline to file a
    third-party claim for contribution against the United
    States); Piamba Cortes v. American Airlines, Inc., 
    177 F.3d 1272
    , 1305 (11th Cir. 1999) (assuming that a state law
    claim for contribution was proper under the Warsaw
    Convention). Our conclusion that the Warsaw Conven-
    tion is compatible with a state law contribution scheme,
    therefore, is consistent with the interpretation of other
    circuits.
    Although we conclude that a claim for liability under
    the Warsaw Convention is compatible with a claim for
    contribution or setoff under the JTCA, our inquiry does not
    end there. A party seeking contribution or a right of
    setoff under the JTCA must show that the plaintiff poten-
    tially had “a cause of action sounding in tort against both
    the party seeking contribution and the party from whom
    contribution is sought.” N. American, 
    89 F.3d at 456
     (em-
    phasis added). To seek a setoff under the JTCA, then,
    NCA must show that Sompo could have brought a claim
    sounding in tort against Pace and/or Yusen as well as
    against the air carrier. Sompo does not dispute that Yusen
    was potentially liable in tort here; accordingly, NCA is
    Nos. 06-3942 & 06-4032                                       19
    entitled to a setoff of the $8,500 Yusen paid to Sompo in the
    settlement. Pace, however, was potentially liable only
    under the Carmack Amendment, a fact that, as we have
    already discussed, precludes NCA from seeking a setoff
    of its payments under the JTCA. See N. American, 
    89 F.3d at 458
    .
    Even if Pace is not a potential “tortfeasor” within the
    meaning of the JTCA, however, NCA can claim a setoff
    right based on Illinois common law. See, e.g., Maher v.
    Chicago Park Dist., 
    645 N.E.2d 295
    , 297 (Ill. App. Ct. 1994)
    (noting that the JTCA is not the sole source of a setoff
    right, and a setoff right existed at common law); Hentze
    v. Unverfehrt, 
    604 N.E.2d 536
    , 541 (Ill. App. Ct. 1992)
    (holding that a right of setoff is implied in contract cases,
    even if not statutorily encompassed by the JTCA); Johnson
    v. Belleville Radiologists, Ltd., 
    581 N.E.2d 750
    , 753 (Ill. App.
    Ct. 1991) (“The provision for a setoff contained in the
    Contribution Act is not the source of the defendants’ right
    to a setoff; it is merely a codification of that right. Defen-
    dants were entitled to a setoff at common law.”). Sompo
    does not dispute the existence of this common law right,
    and therefore we conclude that NCA is entitled to a
    setoff of the entire settlement amount.
    In sum, we hold that the Illinois Joint Tortfeasors Contri-
    bution Act is not preempted by the Warsaw Convention,
    and that NCA is entitled to a setoff of the entire amount
    of the settlement under the JTCA and Illinois common
    law. We next must determine whether the setoff should
    be taken from the capped judgment amount ($74,450.84),
    reducing Sompo’s award to zero, or from the total proven
    damages amount ($271,304), granting Sompo the maxi-
    mum damages allowable under the Convention.
    20                                    Nos. 06-3942 & 06-4032
    B. To Which Amount Does the Setoff Apply?
    The district court found that the plaintiff in this case had
    sustained at least $271,304 in proven damages. Applying
    Illinois contribution law, it then reduced that amount by
    $108,500, the amount that Sompo had received from Pace
    and Yusen in settlements. The court therefore concluded
    that Sompo was entitled to $162,804 in damages. As the
    Warsaw Convention capped NCA’s liability at $74,450.84,
    however, the district court awarded Sompo only
    $74,450.84.
    On appeal, NCA contests the district court’s method of
    calculation. It submits that Sompo’s $108,500 settlement
    with Pace and Yusen instead should have been applied
    against the $74,450.84 limited liability figure, effectively
    reducing NCA’s liability to $0. Sompo, on the other
    hand, contends that the settlement amount correctly
    was deducted from its total amount of proven damages,
    or $271,304, leaving NCA responsible for the full amount
    permissible under the Warsaw Convention. We review
    de novo the district court’s decision to apply the setoff
    to the total damage amount rather than to the reduced
    liability amount. See Johnson v. West, 
    218 F.3d 725
    , 729 (7th
    Cir. 2000).
    The JTCA provides that a plaintiff’s settlement with a
    joint tortfeasor “reduces the recovery on any claim” against
    a non-settling defendant. 740 Ill. Comp. Stat. 100/2(c). In
    NCA’s view, the term “recovery” means the “amount
    finally collected” by a plaintiff. Black’s Law Dictionary
    1276 (6th ed. 1990). Without citing legal authority, NCA
    contends that the plain meaning of this statute therefore
    requires the court to apply the setoff against the amount
    finally collectable by the plaintiff—here, the $74,450.84
    ultimately recoverable under the Warsaw Convention.
    Nos. 06-3942 & 06-4032                                      21
    In practice, however, NCA’s so-called “plain meaning”
    reading of the statute makes little sense. As the district
    court aptly noted, “[i]f the setoff were to be deducted
    from the ‘amount finally collected’ by a plaintiff, . . . the
    latter would no longer be the amount ‘finally collected.’
    Applying the ‘plain meaning’ leads to an absurd result.”
    Sompo Japan Ins., Inc. v. Nippon Cargo Airlines Co., No. 02
    C 9311, 
    2004 WL 2931282
    , at *9 (N.D. Ill. Dec. 15, 2004).15
    Contrary to NCA’s defendant-centered approach, an
    Illinois court has said that the JTCA requires a setoff so that
    “a payment by one tortfeasor diminishes a plaintiff’s claim
    against all other tortfeasors responsible for the same
    harm.” Hentze, 
    604 N.E.2d at 541
    . The court focused on
    the plaintiff’s proven damages, not the defendant’s ulti-
    mate liability: “The underlying current . . . is that a plain-
    tiff’s claimed damages are to be reduced by any payments
    he has received in compensation for the same harm or
    injury.” 
    Id.
    The purpose underlying the JTCA is the “long-recog-
    nized principle in Illinois that a plaintiff shall have only
    one satisfaction for an injury.” Pasquale, 
    654 N.E.2d at 1381
    .
    15
    Indeed, NCA’s definition of “recovery” is not the only
    possible definition of the term. Black’s Law Dictionary also
    defines the term “recovery” as, “in its most extensive sense,
    the restoration or vindication of a right.” Black’s Law Dic-
    tionary 1147 (5th ed. 1979). According to this definition,
    “recovery on a claim” could mean the restoration or vindica-
    tion of the plaintiff’s total damages—in short, making the
    plaintiff whole. Such a definition comports with the district
    court’s interpretation of the Act, which would focus on vin-
    dication of the plaintiff’s claim rather than the amount the
    defendant ultimately pays.
    22                                    Nos. 06-3942 & 06-4032
    The setoff right is plaintiff-centered, rather than focused on
    the unique characteristics of the defendant. See Maher v.
    Chicago Park Dist., 
    645 N.E.2d 295
    , 298 (Ill. App. Ct. 1994)
    (noting that a defendant may receive a setoff in order to
    prevent a plaintiff from receiving double recovery for the
    same injury, irrespective of the defendant’s actions).
    Therefore, applying the setoff to the plaintiff’s total dam-
    ages, rather than the defendant’s total liability, com-
    ports with the intent of the statute.
    Such a result, as NCA suggests, conceivably could be
    perceived as allowing “double recovery” for Sompo, for
    although only NCA was held responsible for the accident,
    Sompo recovered from multiple parties. Indeed, Sompo
    recovered more in its settlement with Pace than it probably
    would have been awarded had all the parties gone to trial.
    This is not, however, the double recovery about which
    the JTCA is concerned. Presumably, the settlement amount
    recovered from Pace and Yusen was discounted by
    those parties to reflect their estimation of the probability
    that they would be found responsible for the accident.
    Although, in hindsight, it appears that the settling defen-
    dants paid far more than their legal liability, avoiding the
    risk and the cost of litigation apparently was worth the
    price of settlement for Pace and Yusen. Courts do not
    second-guess such decisions absent evidence of bad faith.
    Cleveringa v. J.J. Case Co., 
    549 N.E.2d 877
    , 880 (Ill. App. Ct.
    1990). The purpose of the setoff statute is defeated by
    a recovery from this type of settlement only if the plain-
    tiff’s aggregate recovery is greater than his actual proven
    damages.
    Here, Sompo receives no unfair windfall by recovering
    from both Pace and NCA. Even with recovery from both,
    Sompo is still substantially under-compensated. The dis-
    Nos. 06-3942 & 06-4032                                     23
    trict court found that Sompo’s total damages were at
    least $271,304. The Pace/Yusen settlement of $108,500 left
    Sompo with $162,804 in unpaid damages. “Given that
    NCA’s liability is limited to $74,450.84,” the district court
    noted, “Sompo will not recover even one full compensa-
    tion for its injuries, much less ‘double recovery.’ ” Sompo,
    
    2004 WL 2931282
    , at *9.
    On the other hand, NCA would receive a hefty windfall
    were we to accept its interpretation of the JTCA. NCA asks
    that we apply the amount of Pace’s and Yusen’s settle-
    ments to its already-capped liability amount, reducing
    the judgment against it to zero and leaving Sompo with
    $162,804 in uncompensated damages. Under NCA’s
    interpretation, despite the fact that NCA was found by
    the district court to have been the sole party responsible
    for the loss, it would be free from paying any damages.
    The entire burden would fall upon Pace, Yusen and the
    plaintiff—all innocent parties. Surely this is not the result
    required by the JTCA, an act intended to properly distrib-
    ute losses among culpable parties. See Doyle, 
    461 N.E.2d at 386, 388
     (stating that the JTCA was designed to “reach
    anyone who is culpable regardless of whether they have
    been immunized from a direct tort action by some
    special defense or privilege,” and to enforce “an equitable
    duty to share liability for the wrong done”); see also Jansen
    v. Aaron Process Equip. Co., 
    149 F.3d 603
    , 609 (7th Cir. 1998)
    (noting that “the culpable tortfeasor rather than the in-
    jured victim will bear the financial responsibility” when
    faced with an inequitable distribution of loss).
    Such a result does not contradict the purposes of the
    Warsaw Convention. Certainly, one of the leading pur-
    poses of the original Warsaw Convention was to limit the
    potential liability of air carriers. However, beginning
    24                                    Nos. 06-3942 & 06-4032
    with the Montreal Agreement and MP4, and culminating
    in the most recent Montreal Convention,16 the modern
    Warsaw regime has been driven by an attempt to better
    balance the interests of air carriers and potential plain-
    tiffs. This goal is achieved by limiting air carriers’ potential
    liability to predictable, non-catastrophic damages and also
    by preserving a plaintiff’s right to recover its losses up to
    a certain amount. Applying the setoff to the total amount
    of damages in this case results in a greater amount of
    liability for the airline than if the statute had directed us to
    take the reduction from the capped amount. Even when
    applying the setoff to the total damages amount, how-
    ever, the airline retains the protection of the Warsaw
    Convention’s liability cap and therefore is assured that its
    liability is predictable and limited. Our interpretation of
    the setoff rule in no way increases the air carriers’ risk of
    being subjected to unpredictable or catastrophic damages.
    Accordingly, we conclude that the judgment of the
    district court was correct. NCA is entitled to a setoff of the
    settlement amounts, but the amount must be subtracted
    from Sompo’s total proven damages rather than from
    NCA’s limited liability under the Warsaw Convention.
    Because Sompo’s post-settlement uncompensated dam-
    ages far exceeded Sompo’s liability under the Warsaw
    Convention, the award of $74,450.84 was correct.
    16
    We recognize, of course, that the Montreal Convention is
    not directly applicable to the instant case, as it was ratified
    after the events in question. Nevertheless, the trend toward
    increased protection for consumers may inform our inter-
    pretation of the Warsaw Convention, as amended by MP4, in
    this case.
    Nos. 06-3942 & 06-4032                                            25
    D. Prejudgment Interest
    In its cross-appeal, Sompo asks that we award prejudg-
    ment interest on the judgment amount. The Supreme
    Court has not addressed the availability of prejudgment
    interest under the Warsaw Convention. This court, how-
    ever, previously has held that prejudgment interest is not
    appropriate under the terms of the treaty. Deere & Co. v.
    Deutsche Lufthansa Aktiengesellschaft, 
    855 F.2d 385
     (7th
    Cir. 1988).
    In Deere, we held that the Warsaw Convention’s goal of
    fixing uniform limits on damages for airlines was “inher-
    ently incompatible with full compensation to all custom-
    ers.” 
    Id. at 392
    . Consequently, making aggrieved airline
    customers whole “was not a primary purpose of the
    Convention.” 
    Id.
     By contrast, “[t]he preeminent purpose
    of the Convention was to fix definite and uniform limits
    on the cost to airlines,” and allowing additional prejudg-
    ment interest would contradict this goal. 
    Id. at 391

    Sompo suggests that Deere was decided before the
    Montreal Protocol took effect in the United States, and thus
    it is not necessarily a binding interpretation of current law.
    Although the Deere opinion was written before MP4
    became effective, the court was not unaware of the exis-
    tence of the law. In fact, we addressed the Montreal
    Protocol as persuasive authority in interpreting the Con-
    17
    This decision comported with the Second Circuit’s holding in
    O’Rourke v. Eastern Air Lines, 
    730 F.2d 842
     (2d Cir. 1984),
    although it is in conflict with decisions in the Fifth Circuit and
    the Ninth Circuit. See Motorola, Inc. v. Fed. Express Corp., 
    308 F.3d 995
     (9th Cir. 2002); Domangue v. E. Airlines, Inc., 
    722 F.2d 256
    (5th Cir. 1984).

    vention. 
    Id. at 392
    . We specifically determined that MP4’s
    additional goals of speedy settlement of claims, as well as
    some limited additional protection of the consumer,
    were not significantly served by awarding prejudgment
    interest. 
    Id. at 392
    . As illustrated in this case, because
    airlines are willing to incur substantial fees to litigate the
    issues of damages, “prejudgment interest would constitute
    only a minor deterrent to litigation-caused delays in
    payment.” 
    Id.
     The overarching goal of the Warsaw Con-
    vention, to fix an airline’s potential damages at a predict-
    able level, would not be served by allowing discretionary
    prejudgment interest.
    Sompo has failed to meet its burden of persuading us
    that, despite the doctrine of stare decisis and precedent,
    we ought to overhaul or modify our holding in Deere.
    Conclusion
    For the reasons explained above, we affirm the judg-
    ment of the district court.
