    Before ROVNER, EVANS, and SYKES, Circuit Judges.
    SYKES, Circuit Judge. First National Bank of Manitowoc
    extended credit to a local used-car dealership based in part
    on the dealership’s presentation of leases signed by its
    customers. Unbeknownst to the Bank, in many instances
    the dealership’s president forged customers’ signatures
    on leases that were fabricated or altered. The dealership
    eventually defaulted on the loans, and the Bank lost
    more than $1.7 million. The Bank filed a claim for the loss
    with its insurer, Cincinnati Insurance Company. The
    2                          Nos. 05-4762, 06-1144 & 06-2044
    policy Cincinnati had issued to the Bank was similar but
    not identical to an outdated version of the standard
    Bankers Blanket Bond, now known as a Financial Institu-
    tions Bond. Generally speaking, these bonds provide
    coverage to financial institutions for losses caused by
    specified dishonest, fraudulent, or criminal acts.
    Cincinnati denied the Bank’s claim and this suit ensued.
    Both parties moved for summary judgment. The district
    court denied Cincinnati’s motion and granted the Bank’s
    in substantial part, rejecting only its claim for statutory
    interest. Both parties appealed. Because the Cincinnati
    policy covers the Bank’s losses and statutory interest
    was properly denied, we affirm.
    I. Background
    First National Bank of Manitowoc is a national bank
    headquartered in Manitowoc, Wisconsin. In 1991 the Bank
    began doing business with West Town Auto, Inc., a used-
    car dealership also located in Manitowoc. The Bank had
    several lending relationships with West Town, including
    a line of credit through which West Town purchased
    vehicles to lease. West Town would enter into a prelimi-
    nary lease agreement with a customer at the dealership,
    and Lee Kust, West Town’s president, would procure a
    loan to purchase the vehicle.
    Kust would call the Bank or fax it the lease terms
    and wait for the Bank’s approval.1 Once the lease was
    approved (sometimes several days later), Kust would
    finalize the transaction with his customer and bring the
    signed lease agreement to the Bank. At that time Kust
    would execute several documents, including a business
    1
    Manitowoc is a small community, so many of the “lessees” were
    familiar to the Bank and were in fact Bank customers.
    Nos. 05-4762, 06-1144 & 06-2044                             3
    note, an assignment of lease payments, and a chattel
    security agreement granting the Bank a security inter-
    est in the vehicle. Under the terms of its line of credit with
    the Bank, West Town was responsible for making loan
    payments to the Bank; West Town’s customers made
    their lease payments directly to West Town.
    The facts surrounding Kust’s fraud are undisputed. The
    scam worked in one of two ways: Kust either fabricated a
    lease agreement for a nonexistent vehicle and transaction
    or altered the terms of a valid lease agreement and
    submitted the altered version to the Bank.2 (As examples
    of the latter fraud, Kust would alter a vehicle’s condition,
    make, or model, thereby enabling him to obtain a larger
    loan.) Under both scenarios, Kust forged customer signa-
    tures by tracing a valid signature onto a fabricated or
    altered lease form. In 2001 Kust suddenly disappeared
    and West Town defaulted on the loan. Until then, however,
    West Town had been making monthly payments as
    required, although the Bank had assessed late charges
    on several occasions.
    Cincinnati does not suggest that any Bank employees
    were aware of Kust’s fraudulent scheme, but the insurer
    does point to what it says are “red flags” during the course
    of the lending relationship that it believes ought to af-
    fect coverage. For example, the Bank did not have a copy
    of each vehicle’s certificate of title and relied on Kust to
    record and perfect its security interest. Bank employees
    were aware that lien confirmations were not on file for
    many vehicles, and those that were on file contained
    discrepancies (the vehicle identification number (“VIN”) on
    2
    The unaltered versions, recovered from West Town, were
    typewritten; the altered versions Kust presented to the Bank
    were handwritten.
    4                         Nos. 05-4762, 06-1144 & 06-2044
    the confirmations did not always match the VIN number
    identified on the lease and loan documents). On several
    occasions one VIN number served as collateral for two
    separate loans. After Kust disappeared it only took a few
    phone calls to West Town lessees for the Bank to realize
    there was a problem.
    After the Bank assessed its losses, it sought coverage
    under an insurance policy it had purchased from
    Cincinnati in 2001 called the Depository Institutions
    Blanket Bond, No. B80-534208. The Cincinnati Bond
    borrows from the Bankers Blanket Bond, Standard Form
    No. 24, an industry-standard insurance policy for com-
    mercial banks offered by several carriers. The standard
    Bankers Blanket Bond is “a two-party agreement be-
    tween the underwriter and the insured financial institu-
    tion, pursuant to which the underwriter agrees to indem-
    nify the insured against loss sustained by reason of specific
    perils described under six ‘Insuring Agreements,’ which
    are commonly referred to by the letter designating them
    in the bond.” Peter I. Broeman, An Overview of the Finan-
    cial Institution Bond, Standard Form No. 24, 110 BANK-
    ING L.J. 439, 439-40 (1993). The standard Bond also
    includes several exclusions which subtract from coverage
    provided by the insuring agreements. Cont’l Corp. v. Aetna
    Cas. & Sur. Co., 
    892 F.2d 540
    , 546 (7th Cir. 1989)
    (“[E]xclusions are expressly intended to modify coverage
    clauses and to limit their scope.”); D’Angelo v. Cornell
    Paperboard Prods. Co., 
    207 N.W.2d 846
    , 849 (Wis. 1973);
    Bulen v. West Bend Mut. Ins. Co., 
    371 N.W.2d 392
    , 394
    (Wis. Ct. App. 1985).
    Here, we are primarily concerned with Insuring Agree-
    ment E and Exclusion H. Insuring Agreement E covers
    loss resulting from a financial institution’s good-faith
    reliance on forged or counterfeit documents. Cincinnati’s
    version of Insuring Agreement E reads as follows:
    Nos. 05-4762, 06-1144 & 06-2044                           5
    E. ALL RISK FORGERY
    Loss by reason of the Insured (a) having in good faith
    and in the usual course of business . . . extended any
    credit or assumed any liability or otherwise acted upon
    any security, document, or other written instrument
    which proves to have been a forgery or to have been
    altered or raised or counterfeited . . . .
    ....
    Actual physical possession of such security, docu-
    ment or other written instrument by the Insured . . . is
    a condition precedent to the Insured’s having relied on
    the faith of, or otherwise acted upon, such security,
    document or, other written instrument.
    Forgery is defined in the Cincinnati policy as “the signing
    of the name of another with intent to deceive.” Exclusion
    H excludes coverage for “loss caused by an Employee,
    except when covered under Insuring Agreement A.”
    (Insuring Agreement A covers losses “resulting directly
    from dishonest or fraudulent acts of an Employee.”)
    The Bank submitted a Proof of Claim to Cincinnati for
    coverage under Insuring Agreements D and E of the
    Policy.3 Cincinnati denied coverage and the Bank filed
    suit in state court. Cincinnati removed the case to federal
    court based on diversity jurisdiction, and both parties
    moved for summary judgment. The district court denied
    Cincinnati’s motion and granted the Bank’s motion in
    part, holding that Insuring Agreement E covered the
    Bank’s loss but that questions of fact existed with respect
    to damages. To move the case along, the parties stipu-
    lated to damages (about $1.75 million), and the district
    court awarded the Bank common-law prejudgment inter-
    3
    Because we conclude Insuring Agreement E covers the Bank’s
    loss, we do not address coverage under Insuring Agreement D.
    6                          Nos. 05-4762, 06-1144 & 06-2044
    est at a rate of 5%. The court denied the Bank’s request
    for statutory interest at the higher rate of 12%.
    Both parties appealed. Cincinnati appealed from the
    district court’s orders partially granting the Bank’s mo-
    tion for summary judgment on coverage, denying
    Cincinnati’s motion for summary judgment, denying
    Cincinnati’s motion to strike an affidavit,4 and awarding
    the Bank common-law prejudgment interest. The Bank
    appealed from the district court’s order awarding interest,
    arguing that it is entitled to statutory prejudgment
    interest at a rate of 12% under section 628.46 of the
    Wisconsin Statutes.
    II. Discussion
    We review a district court’s grant of summary judgment
    de novo. “With cross summary judgment motions, we
    construe all facts and inferences therefrom ‘in favor of
    the party against whom the motion under consideration
    is made.’ ” In re United Airlines, Inc., 
    453 F.3d 463
    , 468
    (7th Cir. 2006) (quoting Kort v. Diversified Collection
    Servs., Inc., 
    394 F.3d 530
    , 536 (7th Cir. 2004)). Summary
    judgment is appropriate if “there is no genuine issue as to
    any material fact and . . . the moving party is entitled to
    a judgment as a matter of law.” FED. R. CIV. P. 56(c). The
    parties agree that Wisconsin law governs this diversity
    suit.
    4
    We do not address the district court’s denial of Cincinnati’s
    motion to strike the affidavit because the affidavit is relevant
    only to the amount of damages the Bank is entitled to collect,
    and the parties stipulated to that amount.

    A. Coverage Under the Cincinnati Bond
    The interpretation of an insurance policy is a question of
    law that is reviewed de novo. Cont’l Corp., 892 F.2d at 543
    (citing Kraemer Bros. v. United States Fire Ins. Co., 
    278 N.W.2d 857
    , 860 (Wis. 1979)); Folkman v. Quamme, 
    665 N.W.2d 857
    , 864 (Wis. 2003). An insurance policy is
    construed to give effect to the intent of the parties as
    expressed in the language of the policy, which is inter-
    preted as a reasonable person in the position of the
    insured would understand it. Folkman, 665 N.W.2d at
    864; Danbeck v. Am. Family Mut. Ins. Co., 
    629 N.W.2d 150
    , 153 (Wis. 2001). If the language of the policy is
    plain and unambiguous, it is enforced as written, without
    resort to rules of construction. Folkman, 665 N.W.2d at
    864; Danbeck, 629 N.W.2d at 154. Policy language is
    interpreted not in isolation but in the context of the policy
    as a whole. Folkman, 665 N.W.2d at 866. If the policy
    language is ambiguous, it is construed against the insurer
    and in favor of coverage. Id. at 864; Frost ex rel. Anderson
    v. Whitbeck, 
    654 N.W.2d 225
    , 230 (Wis. 2002) (“If terms
    in an insurance policy are ambiguous, they should be
    construed against the insurance company that drafted
    the policy.”); Danbeck, 629 N.W.2d at 154.
    This last principle, however, generally does not apply
    where the policy in question is a standard “fidelity” or
    Bankers Blanket Bond, drafted by representatives from
    both the banking and insurance industries. Tri City Nat’l
    Bank v. Fed. Ins. Co., 
    674 N.W.2d 617
    , 621-22 (Wis. Ct.
    App. 2003) (citing State Bank of Viroqua v. Capitol Indem.
    Corp., 
    214 N.W.2d 42
    , 43 n.1 (Wis. 1974)) (“These bonds
    are not the usual contracts of adhesion and the familiar
    rule of interpreting a contract strictly against the insurer
    and liberally in favor of the insured should not apply.”);
    Sharp v. Fed. Sav. & Loan Ins. Corp., 
    858 F.2d 1042
    , 1046
    (5th Cir. 1988) (the principle that insurance contracts
    8                        Nos. 05-4762, 06-1144 & 06-2044
    are to be construed against the underwriter does not
    apply when “the contract was in fact a joint effort of both
    insurers and the insureds”). As best we can tell, the
    language of the Cincinnati Bond appears to generally—but
    not uniformly—resemble an older version of the standard
    Bankers Blanket Bond. Accordingly, any ambiguity in
    language unique to the Cincinnati Bond may be resolved
    by reference to the general practice of construing am-
    biguities against the insurer/drafter and in favor of
    coverage.
    A brief history of the standard Bankers Blanket Bond
    is in order. The Surety Association of America drafted the
    first American Bankers Blanket Bond in 1916. Edward G.
    Gallagher, A Concise History of Standard Form No. 24,
    1986 Edition, in ANNOTATED FINANCIAL INSTITUTION
    BOND 5, 5 (Michael Keeley ed., 2d ed. 2004). By 1941 the
    Bond had undergone several revisions—with input from
    the American Bankers Association and other trade
    groups—and was termed the “Bankers Blanket Bond,
    Standard Form No. 24.” Broeman, An Overview of the
    Financial Institution Bond, supra, at 443; Gallagher, A
    Concise History, supra, at 6. Additional revisions were
    made over the years, and beginning with the 1986 revision,
    the Bond was renamed the “Financial Institution Bond,
    Standard Form No. 24.” Gallagher, A Concise History,
    supra, at 5. The standard Bond contains six Insuring
    Agreements (Insuring Agreements A-F) which cover the
    insured financial institution against loss arising from
    specified dishonest, fraudulent, or criminal acts. Broeman,
    An Overview of the Financial Institution Bond, supra,
    at 440.
    Because there are several revisions of the Bond in
    circulation, courts initially ought to determine which
    version, if any, the policy in question adopts; case law
    interpreting one revision may be unhelpful or even irrele-
    Nos. 05-4762, 06-1144 & 06-2044                           9
    vant to the task of interpreting another. The language of
    the Cincinnati Bond is not entirely consistent with the
    standard Bond version, the 1986 revision, in use at the
    time it was issued. For example, the Cincinnati Bond adds
    eight Insuring Agreements to the standard Bond’s six,
    covering such additional risks as “Directors’ and Officers’
    Expenses in Defending Suits,” “All Risk Safe Deposit Box,”
    and “Audit Expense.” Insuring Agreement E, at issue
    here, is called “All Risk Forgery” and most closely resem-
    bles Insuring Agreement E as it appeared in the 1951 and
    1969 revisions of the standard Bond, though it does not
    precisely track the language of either of these versions.
    As noted above, Insuring Agreement E in the Cincinnati
    Bond covers “loss by reason of the Insured . . . having
    in good faith and in the usual course of business . . .
    extended any credit or assumed any liability or otherwise
    acted upon any security, document, or other written
    instrument which proves to have been a forgery or to have
    been altered or raised or counterfeit.” Cincinnati argues
    that the “in good faith and in the usual course of business”
    language imposes a duty on the Bank to follow “sound
    banking practices” in connection with the events under-
    lying the claim, and that this is a condition for coverage.
    We disagree. Although we interpret the policy as a whole,
    to interpret “in good faith” and “in the usual course of
    business” as together imposing a prerequisite normative
    standard of banking conduct ignores the independent
    meaning of each phrase. Rabinovitz v. Travelers Ins. Co.,
    
    105 N.W.2d 807
    , 811 (Wis. 1960) (“Some meaning must
    be given to each sentence, phrase, and word used, and
    when this may fairly and properly be done, no part of the
    language used can be rejected as superfluous or unmean-
    ing.”).
    Neither phrase is defined by the policy, but the Bank
    points to section 401.201(19) of the Wisconsin Statutes,
    10                           Nos. 05-4762, 06-1144 & 06-2044
    adopting the UCC definition of “good faith” as “honesty in
    fact in the conduct or transaction concerned.” We have
    stated that “’good faith’ usually establishes a subjective
    standard,” and pointed out that “[m]any negligent acts are
    committed with pure hearts and empty heads.” State Bank
    of the Lakes v. Kan. Bankers Sur. Co., 
    328 F.3d 906
    , 909
    (7th Cir. 2003). Cincinnati asserts there are material
    issues of fact regarding whether the Bank was “selectively
    ignorant” in extending credit to Kust;5 however, its
    corporate designee conceded that Bank employees acted
    honestly and in good faith, with no knowledge of Kust’s
    fraudulent scheme.6 We hold the good-faith requirement
    does not impose a “sound business practices” prerequisite
    to coverage.
    5
    Cincinnati argues that Bank employees “selectively ignored”
    red flags such as titling defects, late charges, and inflated
    residual values for the vehicles, but this does not establish a
    lack of good faith. It is not as if the Bank extended credit based
    on documents that looked suspicious; the leases appeared
    legitimate and the names Kust forged were in most cases Bank
    customers, so the Bank had no reason to doubt the lessee’s
    existence. Until Kust disappeared, West Town was making its
    payments on the loans. Even if Bank employees acted negli-
    gently, the Wisconsin Supreme Court has held that mere
    negligence on the part of an insured does not bar the insured
    from obtaining coverage under a Banker’s Blanket Bond “un-
    less . . . [the negligence] is such that it amounts to fraud or bad
    faith.” First Nat’l Bank of Crandon v. United States Fid. & Guar.
    Co. of Balt., 
    137 N.W. 742
    , 745 (Wis. 1912).
    6
    Cincinnati’s corporate designee, Charles Armentrout, testified
    the Bank acted in good faith: “I think they acted in good faith;
    that they had no intent—I think to act in bad faith you have
    to have some intent to do something wrong, and I don’t think
    there was any conscious intent on the part of anyone at the
    bank to do anything that was going to cause a loss to the bank.”
    Nos. 05-4762, 06-1144 & 06-2044                             11
    This leaves the question of whether the phrase “in the
    usual course of business” means “consistent with sound
    business practices” or otherwise imposes a particular
    standard of conduct on the Bank for its loss to be covered.
    On its face, the phrase does not suggest a duty of care but,
    rather, a certain category of acts—i.e., those usually
    conducted in the banking business. Because the language
    of the Cincinnati Bond is not standard in this respect,7
    bond-specific case law provides little guidance. However,
    Wisconsin courts that have addressed this phrase in
    other contexts have understood it to mean actions nor-
    mally taken by a bank. Fid. & Deposit Co. of Md. v.
    Peoples Exch. Bank of Thorp, 
    71 N.W.2d 290
    , 292 (Wis.
    1955) (“The check here was complete and regular on its
    face and, so far as the . . . bank was concerned, it had no
    notice of any infirmity in it or any defect in the title of
    the person cashing it, and took it in the usual course of
    business.”); Banking Comm’n v. First Wis. Nat’l Bank of
    Milwaukee, 
    290 N.W. 735
    , 749 (Wis. 1940) (“The usual
    course of business upon a bank loan is to credit the
    account of the borrowing customer and respond to
    checks.”).
    This is the interpretation the district court adopted in
    its well-reasoned opinion, and we agree. Because the
    Bank acted “upon the kinds of documents that it would
    normally act upon in its business, such as leases, checks,
    securities, etc., rather than documents outside that usual
    7
    As we have noted, the language of Insuring Agreement E in the
    Cincinnati Bond most closely resembles the 1951 and 1969
    versions of the standard Bond, which used the formulation “in
    good faith and in the course of business.” Beginning with the
    1980 revision, the “in the course of business” language was
    dropped from the standard Bond.
    12                          Nos. 05-4762, 06-1144 & 06-2044
    course,” the Bank acted in the usual course of business.8
    Fid. & Deposit Co. of Md., 71 N.W.2d at 292.
    Cincinnati also argues that Insuring Agreement E covers
    only losses directly caused by forgery and not losses aris-
    ing from loans made on forged documents describing
    nonexistent assets or transactions. Here, Cincinnati
    argues, the forged signatures on the leases did not directly
    cause the Bank’s loss, the absence of collateral did. This
    argument ignores the plain language of Insuring Agree-
    ment E, which covers “loss by reason of the Insured hav-
    ing in good faith and in the usual course of business . . .
    extended any credit or . . . otherwise acted upon any . . .
    document . . . which proves to have been a forgery.” The
    Bank’s loss easily comes within this language; the Bank
    sustained a loss because it extended credit to West Town
    based on vehicle leases which proved to be forgeries.
    Insuring Agreement D in the Cincinnati Bond, entitled
    “Forgery, Alteration and Unauthorized Signatures,” covers
    (among other things) “loss resulting directly from . . .
    Forgery or alteration of, on or in any Negotiable instru-
    ment . . . , Acceptance, withdrawal order, receipt for the
    withdrawal of Property, Certificate of Deposit or Letter
    of Credit.” Insuring Agreements D and E thus cover
    similar and potentially overlapping categories of loss, but
    the language of each is distinct: the former covers
    8
    Even if we determined that Cincinnati’s interpretation of “in
    the usual course of business” language was a reasonable alter-
    native interpretation, this would at best establish an ambiguity,
    i.e., that this language is reasonably susceptible to more than
    one interpretation. Folkman v. Quamme, 
    665 N.W.2d 857
    , 868
    (Wis. 2003). Because the Cincinnati Bond language departs from
    the standard Bond language in use at the time it was is-
    sued—and does not even use the same formulation of earlier
    versions—we would construe the ambiguity against Cincinnati
    and in favor of coverage.
    Nos. 05-4762, 06-1144 & 06-2044                                13
    loss resulting directly from the forgery or alteration of
    certain documents, the latter covers loss “by reason of ” the
    Bank having “extended any credit” or otherwise “acted
    upon” a document “which proves to have been a forgery.”
    The coverage granted in Insuring Agreement E does not
    simply duplicate the coverage granted in Insuring Agree-
    ment D; Cincinnati’s interpretation essentially conflates
    the two.
    Cincinnati asserts that “courts have overwhelmingly
    held” that Insuring Agreement E does not cover losses
    from loans based on forged documents describing ficti-
    tious transactions or assets. This is not true. Of the cases
    Cincinnati cites, only four are appellate decisions. Two of
    the four concerned not loss causation but the so-called
    “actual physical possession” prerequisite to coverage
    under Insuring Agreement E.9 See Republic Nat’l Bank of
    Miami v. Fid. & Deposit Co. of Md., 
    894 F.2d 1255
    , 1262-
    63 (11th Cir. 1990) (holding that the condition precedent
    of actual physical possession was unmet and suggesting

    9
    Cincinnati briefly argues that there is no coverage because
    the Bank did not have actual physical possession of the original
    leases but only the forged “pressure carbon copies,” and therefore
    the “actual physical possession” requirement of Insuring Agree-
    ment E is not met. But the Bond language does not require
    possession of “original” documents; to interpret the “actual
    physical possession” requirement as Cincinnati suggests would
    amount to rewriting the policy. See Danbeck v. Am. Family Mut.
    Ins. Co., 
    629 N.W.2d 150
    , 154 (Wis. 2001) (Courts enforce plain
    policy language as written “to avoid rewriting the contract by
    construction and imposing contract obligations that the parties
    did not undertake.”). Furthermore, as the district court noted,
    the forged pressure carbon copies—the ones the Bank actually
    possessed—were the documents the Bank “acted upon” in
    extending credit, and so the “actual physical possession” condi-
    tion is satisfied.

    Bank of Minneapolis v. St. Paul Fire & Marine Ins. Co.,
    
    447 N.W.2d 171
    , 177 (Minn. 1989) (holding that the actual
    physical possession condition was not met and likewise
    suggesting in dicta a “sound business practices” reliance
    requirement). Another of Cincinnati’s cited cases held
    that the record evidence established a fraud but not a
    forgery because the documents in question were not signed
    in the name of another. Charter Bank Nw. v. Evanston Ins.
    Co., 
    791 F.2d 379
    , 382 (5th Cir. 1986). Here, it is undis-
    puted that the leases were forgeries.
    The remaining appellate decision Cincinnati cites on this
    point was scantily reasoned. Georgia Bank & Trust v.
    Cincinnati Insurance Co., 
    538 S.E.2d 764
    , 766 (Ga. Ct.
    App. 2000), involved a Cincinnati Bond similar to the one
    at issue here. Georgia Bank & Trust extended credit based
    on forged documents confirming the existence of certain
    accounts that served as collateral for the loan. When the
    debtor defaulted, Georgia Bank filed a claim for its loss
    with Cincinnati. The Georgia court of appeals cited both
    Insuring Agreements D and E in its very brief opinion;
    without specifically addressing the language of either, the
    court accepted Cincinnati’s argument that its Bond does
    not cover losses resulting from the nonexistence of assets
    assigned by a forged instrument. The court concluded that
    “the blanket bond did not protect the bank from its bad
    business deal. Even if the signature on the confirmation
    was authentic, the bank would have suffered the loss,
    because the assets did not exist.” 
    Id.
     This conclusion
    ignores the practical reality of the situation; but for the
    forged documents purporting to verify the existence of
    the collateral, credit would not have been extended in the
    first place, and there would have been no loss. It also
    ignores the plain language of Insuring Agreement E, which
    covers loss “by reason of ” the Bank “having . . . extended
    Nos. 05-4762, 06-1144 & 06-2044                           15
    any credit . . . or otherwise acted upon any . . . document”
    that “proves to have been a forgery.” As here, the loss
    at issue in Georgia Bank easily fit within this coverage
    language. The case is unpersuasive and we decline to
    follow it.
    So the Bank’s loss is covered by Insuring Agreement E,
    and we are left with Cincinnati’s argument that Exclusion
    H applies because Bank employees caused the loss. This
    argument is a nonstarter. Exclusion H states: “The Bond
    does not cover loss caused by an Employee . . . .”
    Cincinnati insists the Bank’s employees caused the loss
    by failing to properly investigate the collateral presented
    by Kust. Had they done so, Cincinnati argues, they would
    have discovered the forgeries. As the district court noted,
    however, this interpretation of Exclusion H would elimi-
    nate coverage under Insuring Agreements D and E in all
    cases, as bank employees are intermediaries in every
    forgery-related bank loss. Exclusions are intended to
    subtract from or limit coverage in specified circumstances.

    They do not operate as complete cancellations of coverage
    granted in the insuring agreements. To the contrary,
    under Wisconsin law exclusions are narrowly construed,
    especially if their effect is uncertain. Am. Family Mut. Ins.
    Co. v. Am. Girl Ins. Co., 
    673 N.W.2d 65
    , 73 (Wis. 2004);
    Cardinal v. Leader Nat’l Ins. Co., 
    480 N.W.2d 1
    , 3 (Wis.
    1992). We reject Cincinnati’s expansive interpretation of
    Exclusion H; the exclusion does not apply here.
    B. Prejudgment Interest
    The district court’s award of common-law prejudgment
    interest is reviewed for abuse of discretion. The district
    court awarded common-law prejudgment interest at a
    rate of 5%. See McRoberts Software, Inc. v. Media 100,
    Inc., 
    329 F.3d 557
    , 572 (7th Cir. 2003). A plaintiff is
    16                        Nos. 05-4762, 06-1144 & 06-2044
    entitled to prejudgment interest when the amount owed
    to it is “readily determinable” or when there is a “reason-
    ably certain standard of measurement by . . . which one
    can ascertain the amount he owes.” Olguin v. Allstate Ins.
    Co., 
    237 N.W.2d 694
    , 698 (Wis. 1976). Cincinnati argues
    that because there was no reasonably certain standard of
    measurement—as evidenced by the Bank’s changing its
    calculation midway through the litigation—the Bank is
    not entitled to prejudgment interest. This argument
    misses the mark. Amending a damages amount is not
    tantamount to conceding there is no reasonably certain
    standard of measurement. The Bank’s losses can be
    calculated by analyzing the forged leases, the vehicles’
    Black Book and Kelley Blue Book values, and the amount
    the Bank was able to recoup by selling the remaining
    existing vehicles. Admittedly, it may be a cumbersome
    process, but this does not render the Bank’s losses inde-
    terminate.
    Tellingly, any disputes the parties had with respect to
    damages dealt with the substantive issue of the Bank’s
    entitlement to them, not their calculation. More specifi-
    cally, Cincinnati argued that in certain instances the
    Bank acquired physical possession of the forged leases
    only after it issued funds on the line of credit—not before,
    as required by Insuring Agreement E. These losses are
    not covered. The parties were able to resolve these factual
    disputes by stipulating to a damages amount after the
    district court entered summary judgment. The district
    court did not abuse its discretion in awarding common-
    law prejudgment interest.
    For its part, the Bank is not satisfied with 5% interest
    and argues it is entitled to statutory prejudgment interest
    at a rate of 12% pursuant to section 628.46(1) of the
    Wisconsin Statutes. Because the district court correctly
    interpreted section 628.46(1), we review the court’s
    application of the statute to the facts for clear error.
    Nos. 05-4762, 06-1144 & 06-2044                         17
    Thomas v. Gen. Motors Acceptance Corp., 
    288 F.3d 305
    ,
    307 (7th Cir. 2002). Under section 628.46(1), an insurer
    must pay on a proof of claim within thirty days of receipt,
    with all overdue payments subject to interest at the rate
    of 12%, unless the insurer has “reasonable proof to estab-
    lish that [it is] not responsible for the payment.” Reason-
    able proof of nonresponsibility exists when coverage is
    “fairly debatable.” Kontowicz v. Am. Standard Ins. Co. of
    Wis., 
    714 N.W.2d 105
    , 117 (Wis. 2006). The district court
    held that coverage was “fairly debatable” here and we
    agree. The claim raised disputed questions about the
    scope of coverage under the forgery insuring agreements
    of an older and somewhat nonstandard Bankers Blanket
    Bond. There are no Wisconsin cases directly on point and
    little persuasive extrajurisdictional case law exists. This
    makes the claim fairly debatable. The Bank was not
    entitled to statutory prejudgment interest.
    For the foregoing reasons, the Bank’s losses are covered
    under Cincinnati’s version of Insuring Agreement E,
    Exclusion H does not apply, and the Bank is entitled to
    common-law prejudgment interest at a rate of 5%. The
    orders of the district court are AFFIRMED.
