    Case Summary: American Family Mutual Insurance Company (AFM)
    insured one of the defendants, Sideco, Inc., in the underlying dispute concern-
    ing construction defects in a housing development. After judgment was entered
    against Sideco in the underlying action, the FountainCourt plaintiffs sought a
    writ of garnishment against AFM for the amount owed by Sideco. After a hearing,
    the trial court entered a judgment against AFM in FountainCourt’s favor, AFM
    appealed, and the Court of Appeals affirmed. Held: An insurer litigating cover-
    age issues after an insured has been held liable is not estopped by the underlying
    judgment. The underlying judgment, however, must be considered in order for the
    court deciding the coverage issue to determine what the insured became legally
    obligated to pay as damages. The trial court correctly determined as a matter of
    law that the underlying judgment was for property damage, as that term is used
    in the insurance policies at issue. The trial court also correctly determined that
    coverage had been triggered under those policies.
    The decision of the Court of Appeals is affirmed. The supplemental judgment
    for garnishment is affirmed. The supplemental judgment awarding attorney fees,
    costs, and disbursements is reversed as to the attorney fee award and is other-
    wise affirmed.
    344	   FountainCourt Homeowners v. FountainCourt Develop.
    BALDWIN, J.
    American Family Mutual Insurance Company
    (AFM) seeks review of a decision of the Court of Appeals
    that upheld a trial court judgment in a garnishment pro-
    ceeding requiring AFM to pay a judgment that plaintiffs
    FountainCourt Homeowners’ Association and FountainCourt
    Condominium Owners’ Association (FountainCourt) had
    obtained against AFM’s insured, Sideco, Inc. (Sideco).
    FountainCourt Homeowners v. FountainCourt Develop., 
    264 Or App 468
    , 334 P3d 973 (2014). FountainCourt responds
    that the Court of Appeals correctly upheld that supple-
    mental judgment, but argues that that court erroneously
    reversed a subsequent supplemental judgment that awarded
    attorney fees. We reject without discussion FountainCourt’s
    arguments concerning the subsequent supplemental judg-
    ment. With respect to AFM’s arguments, we conclude that
    the Court of Appeals correctly rejected them, and we affirm
    the trial court’s judgment.
    The underlying dispute concerns a housing devel-
    opment that was constructed between 2002 and 2004 in
    Beaverton. FountainCourt brought an action against the
    developers and contractors seeking damages for defects in
    the construction of the buildings in the development. Sideco,
    a subcontractor, was brought in as a third-party defendant,
    and a jury eventually determined that Sideco’s negligence
    caused property damage to FountainCourt’s buildings.
    Based on that jury verdict, the trial court entered judgment
    against Sideco in the amount of $485,877.84. FountainCourt
    then served a writ of garnishment on AFM in the amount
    owed by Sideco, and, in response, AFM denied that the loss
    was covered by its policies. FountainCourt moved for an order
    to show cause in the trial court why judgment should not be
    entered against AFM on the writ of garnishment. The trial
    court ultimately agreed with FountainCourt and entered
    judgment against AFM, after deducting the amounts that
    had been paid by other garnishees. AFM appealed the judg-
    ment, and the Court of Appeals affirmed.
    On review, AFM raises numerous issues, some of
    which, as we explain below, were not properly raised in the
    lower courts, and others of which we reframe for purposes
    Cite as 
    360 Or 341
     (2016)	345
    of organizing our discussion. We have reframed the issues
    before us as follows: (1) Did the trial court properly resolve
    the issues raised in the garnishment proceeding in a man-
    ner that comported with this court’s case law concerning an
    insurer’s duty to defend and right to litigate coverage issues,
    and did not implicate AFM’s right to a jury trial; and (2) did
    the trial court correctly interpret the insurance policies to
    conclude that coverage had been triggered under the poli-
    cies and that AFM was liable to FountainCourt in light of
    FountainCourt’s verdict against Sideco in the underlying
    negligence case? We conclude that the trial court correctly
    resolved those legal issues, and we affirm the trial court and
    the Court of Appeals.
    I.  FACTS AND PROCEDURAL POSTURE
    A.  The Negligence Trial
    Between 2002 and 2004, FountainCourt, a planned
    community, was developed by defendant FountainCourt
    Development and built by defendant Legend Homes
    Corporation,1 and much of the work on the project was carried
    out by subcontractors. The planned community consisted of
    34 condominiums and 63 townhouses. The owners of the con-
    dominiums and townhouses (represented in this litigation by
    the plaintiff homeowners associations) experienced damage
    to their properties caused by water intrusion into the build-
    ings. In 2007, FountainCourt initiated the underlying action
    against the developers and contractor, who, in turn, brought
    in subcontractors as third-party defendants. In an amended
    pleading, FountainCourt alleged direct claims of negligence
    against some of the subcontractors, including Sideco. In par-
    ticular, FountainCourt alleged that Sideco had installed sid-
    ing and windows, among other things, in such a manner as
    to cause water intrusion into the buildings, which resulted in
    physical damage to those structures.
    Sideco tendered defense of the action to its insurers,
    including AFM. Sideco had general-liability insurance pol-
    icies issued by AFM covering the period of May 1, 2004 to
    May 1, 2006, and a general-liability insurance policy issued
    1
    Defendant Matrix Development Corporation is the parent company of both
    FountainCourt Development and Legend Homes Corporation.
    346	    FountainCourt Homeowners v. FountainCourt Develop.
    by Clarendon National Insurance Company covering the
    period of April 15, 2003 to May 15, 2004. Clarendon and
    AFM accepted the tender of defense with a full reservation
    of rights.
    At trial, FountainCourt presented evidence in sup-
    port of its claims. Ultimately, the only theory of the case that
    went to the jury with respect to all defendants concerned
    property damage, and the jury was instructed as follows:
    “If you find that the plaintiffs are entitled to prevail,
    then you must decide whether the plaintiffs have been
    damaged and, if so, the amount of their damages.
    “Plaintiffs must allege and prove physical damage to
    their property. * * * The amount of damages may not exceed
    the sum of $3,831,635. The plaintiffs must prove damages
    by a preponderance of the evidence.
    “If you find the plaintiffs are entitled to damages, you
    should—or shall determine the amount of physical damage
    to plaintiffs’ real property, if any, that was caused by the
    defendants’ fault or negligence. The measure of damages for
    partial destruction of real property is the reasonable cost of
    repairing the damaged property.”
    (Emphasis added.)
    The jury returned a verdict in FountainCourt’s
    favor and allocated percentages of fault to various defen-
    dants. While the main fault (66 percent) was found to be
    with the developer/primary contractor group, various sub-
    contractors also were determined to have been negligent.
    The jury’s verdict indicated that plaintiffs’ total damages
    were $2,145,156, and that 22.65 percent of the damages
    were caused by Sideco’s negligence. The trial court accord-
    ingly entered a judgment against Sideco in the amount of
    $485,877.84.
    B.  The Garnishment Proceeding
    FountainCourt then mailed a writ of garnishment
    to Sideco’s insurers for the amount of its judgment against
    Sideco.2 AFM filed an answer asserting that FountainCourt
    2
    In the garnishment context, FountainCourt was, in essence, standing
    in the shoes of Sideco, which was insolvent at that point in time. See generally
    Cite as 
    360 Or 341
     (2016)	347
    had failed to state a claim. It argued that it was not obli-
    gated to pay the Sideco judgment either because some or all
    of the damages did not arise from “property damage” or an
    “occurrence,” or because some or all of the property damage
    resulted before or after the policy periods, or because one
    or more exclusions applied to some or all of the losses. AFM
    also asserted a counterclaim for declaratory judgment con-
    cerning its liability under the policies. FountainCourt then
    moved for a show-cause order as to why judgment should
    not be entered against the insurers on the writ of garnish-
    ment, seeking a hearing pursuant to ORS 18.775.3 AFM
    and Clarendon objected to resolving the issues by way of a
    hearing pursuant to ORS 18.775, arguing that they needed
    additional time to prepare, that factual issues concerning
    coverage that could not be resolved through such a hearing,
    and that they were entitled to a jury trial on those factual
    issues. The insurers identified as potential factual issues
    pertinent to coverage “the timing and cause of the alleged
    property damage, and the nature of the money damages
    awarded in the underlying action, among other things.” The
    insurers also argued that they had raised “various coverage
    defenses, based upon policy endorsements and exclusions,
    which also will be fact-sensitive and entitle the parties to a
    jury trial.”
    The trial court held a hearing at which the parties
    argued their respective positions concerning how the cover-
    age disputes should be resolved. The court indicated that it
    would not conduct a jury trial, as the meaning of the insur-
    ance policies presented a question of law. AMF’s counsel
    suggested that the court should resolve some preliminary
    questions of law such as “who has the burden of proof” and
    “whether or not it’s even possible at this juncture, based on
    the trial court record that was created, to establish when
    damage occurred, whether it was under one insurer’s pol-
    icy or another.” AMF’s counsel acknowledged that Sideco’s

    , 167, 700 P2d 236 (1985) (garnishor

    Another insurer, Maryland Casualty Company, which insured Sideco
    from April 2002 through April 2003 and had also been served with a writ of
    garnishment, settled with FountainCourt during the course of the garnishment
    proceeding.
    348	     FountainCourt Homeowners v. FountainCourt Develop.
    liability was determined in the underlying action, but argued
    that additional factual issues needed to be determined:
    “One is when did damage occur. We’ve got three insurers.
    They do not have co-extensive policies. One ends. The next
    one begins. And each policy says it only applies to damage
    that occurs during the policy term. It was never an issue in
    the underlying case when damage occurred.”
    Counsel also argued that there were potential issues con-
    cerning the policy exclusions for certain multi-unit struc-
    tures,4 adding that “[w]e’re going to have to assess what
    damages were awarded, if possible in the—by the jury for
    which buildings to determine the applicability of that exclu-
    sion in this particular context.”
    With the issues thus framed by the parties, the trial
    court construed the pertinent provisions of the insurance
    contracts. The AFM insurance policies at issue in this case
    provided that AFM “will pay those sums that the insured
    becomes legally obligated to pay as damages because of * * *
    ‘property damage’ to which this insurance applies.” The
    policies define property damages as “[p]hysical injury to
    tangible property, including all resulting loss of use of that
    property. All such loss of use shall be deemed to occur at
    the time of the physical injury that caused it.” The policies
    also provide that an “occurrence” is “an accident, including
    continuous or repeated exposure to substantially the same
    general harmful conditions.” In addition, the policies con-
    tain the following provisions relating to “property damage”:
    “b.  This insurance applies to * * * ‘property damage’
    only if:
    “* * * * *
    “(2)  The * * * ‘property damage’ occurs during the pol-
    icy period; and
    4
    Both the AFM policies and the Clarendon policy had exclusions for certain
    types of multi-unit structures, but the provisions of those policies differed signifi-
    cantly. The trial court ultimately concluded that Clarendon had met its burden
    of proof with respect to the multi-unit exclusion in its policy. That aspect of the
    court’s decision is not at issue in this appeal.
    Several other policy exclusions were raised at the garnishment hearing, but
    as we explain below, AFM did not raise any issues concerning the trial court’s
    resolution of issues pertaining to exclusions in its assignments of error on appeal,
    and thus we do not address any issues relating to policy exclusions.
    Cite as 
    360 Or 341
     (2016)	349
    “(3)  Prior to the policy period, no insured * * * knew
    that the * * * ‘property damage’ had occurred, in whole or in
    part.
    “* * * * *
    “c.  ‘[P]roperty damage’ which occurs during the policy
    period and was not, prior to the policy period, known to
    have occurred by any insured * * * includes any continua-
    tion, change or resumption of that * * * ‘property damage’
    after the end of the policy period.”
    At the garnishment hearing, FountainCourt main-
    tained that the insurers had the burden of proof to show
    what portion of the jury’s verdict in the underlying case was
    for damages that fell within policy exclusions and that the
    insurers could not meet that burden. It further argued that,
    in situations such as this where there are multiple insur-
    ers on this type of loss, the burden in on the insurers to
    work it out among themselves as to how much each insurer
    pays, and it is not the burden of the insured to show how
    that should be allocated. AFM, in contrast, argued that
    FountainCourt had the burden to establish that the dam-
    ages that were awarded by the jury in the underlying trial
    were for the type of property damage covered by the policy
    and to show how much property damage occurred during
    which policy periods, but that FountainCourt could not meet
    its burden of proof on those issues because the jury’s ver-
    dict was not segregated in a way that allowed such determi-
    nations to be made. In short, both parties argued that the
    other had the burden of proof as to dispositive coverage or
    exclusion issues, and could not meet that burden as a matter
    of law, because it was not possible to get behind the jury’s
    verdict to determine the precise basis on which the jury had
    arrived at its decision concerning the extent of Sideco’s lia-
    bility, when property damage occurred, and the amount of
    property damage.
    The record from the underlying trial was admit-
    ted into evidence. FountainCourt also put on expert testi-
    mony from the inspector who prepared the damage repair
    estimates that were admitted in the underlying trial. He
    testified, based on trial exhibits, about the completion
    dates and composition of each of the buildings, as well as
    350	    FountainCourt Homeowners v. FountainCourt Develop.
    the general nature of the damage, some of which occurred
    when the products were installed, and some which involved
    water damage and that began in the fall or winter after
    the work was done and occurred continuously thereafter.
    He further testified that there was damage to underly-
    ing materials due to defects in Sideco’s work during the
    time that the AFM policies were in effect. He opined that
    it was not possible to quantify how much of the consequen-
    tial water damage occurred during which insurance policy
    period. He further testified that water damage of this type
    increases exponentially the longer it goes unrepaired. The
    witness testified that his firm’s damage estimate allocated
    approximately $1.5 million in damages caused by Sideco’s
    negligence. When asked if the $485,000 awarded by the
    jury against Sideco could all have been awarded to cover
    consequential water damages rather than Sideco’s own
    work,5 he replied that it could have. AFM presented tes-
    timony by a forensic architect who opined that the water
    damage to the buildings could not be precisely defined in
    terms of when it began or ended, and that this type of dam-
    age is cumulative.
    The court concluded that FountainCourt had “met
    its prima facie burden of proving coverage under the poli-
    cies,” that the burden was on AFM “to prove what portions,
    if any, of the judgments entered against Sideco, Inc., are
    excluded by the policies,” and that AFM had not met that
    burden. The court noted specifically that AFM was “unable
    to show whether or how the jury apportioned damages
    among the FountainCourt buildings; accordingly, its multi-
    unit exclusion is inapplicable.” The court entered judgment,
    and AFM appealed.
    C.  The Appeal
    In the Court of Appeals, AFM raised four assign-
    ments of error. It first argued that the court erred in deter-
    mining that FountainCourt had met its initial burden
    because “FountainCourt failed to prove that any, let alone
    all, of the damages awarded against Sideco fell within the
    insuring agreement of its policy.” That argument focused
    5
    One of the policy exclusions that AFM raised concerned excusions of the
    policyholder’s own work.
    Cite as 
    360 Or 341
     (2016)	351
    primarily on whether the damage shown by the evidence
    in the underlying negligence case constituted “property
    damage” within the meaning of the AFM policies. Second,
    AFM argued that, because FountainCourt’s own expert at
    the garnishment hearing testified that it was not possible
    “to segregate the [jury’s] verdict after-the-fact” in the gar-
    nishment proceeding, there was no evidence to support a
    conclusion that “the awarded damages were within Sideco’s
    insuring agreement.” Third, AFM argued that the trial
    court had erred in denying it a jury trial on the issue of what
    part of the damage to the FountainCourt buildings occurred
    during its policy periods. Fourth, it argued that the trial
    court erred in awarding FountainCourt attorney fees.
    The Court of Appeals rejected all but the fourth
    assignment of error. FountainCourt Homeowners, 264 Or
    App at 471. The court first addressed AFM’s argument that
    FountainCourt had failed to meet its burden of proving that
    the jury awarded damages for “property damage” as that
    term was used in its policies. The court noted that AFM’s
    primary argument in that regard was that the jury’s verdict
    could have included costs not only for repairing consequential
    water damage caused by Sideco’s negligence, but also “the
    cost of repairing Sideco’s own faulty work.” Id. at 481. The
    court recognized, however, that the policy provision on which
    AFM relied was not, in fact, a limitation within the policy’s
    definition of “property damage,” but rather was an exclusion
    on which AFM had the burden of proof. Id. at 483-85.
    The court then rejected AFM’s argument that
    FountainCourt was required, and failed, to prove that all
    of the damages awarded in the underlying negligence case
    were for property damage that occurred during its policy
    periods. Id. at 487. It also rejected AFM’s argument that
    the trial court’s conclusion that FountainCourt had met its
    initial burden to show coverage under the Clarendon pol-
    icy as well necessarily meant that some of the damage had
    occurred during the Clarendon policy period instead of the
    AFM policy period, stating that “the award of damages is
    not tied to discrete instances of property damages along a
    time continuum; instead the liability for property damage
    may be the same in every triggered policy period.” Id. On
    the jury question, the court rejected AFM’s argument that
    352	   FountainCourt Homeowners v. FountainCourt Develop.
    a factual issue had been raised because “there was evidence
    presented during the garnishment proceeding that would
    have permitted a jury to find that consequential water
    damage did not occur while American Family was on the
    risk.” Id. at 491. The court explained that the issue in the
    garnishment proceeding was one of law rather than fact:
    “[B]ecause the entry of the judgment triggered American
    Family’s obligation to pay a covered debt, the court was
    called upon to determine the import of that judgment under
    the parties’ contract as a legal matter.” Id. (emphasis in
    original). Therefore, the Court of Appeals affirmed the trial
    court’s judgment on the merits, although it reversed on the
    attorney fee award. Id. at 495. AFM sought review, which
    we allowed.
    D.  Limitations on Review
    Under ORAP 9.20(2), “the questions before the
    Supreme Court include all questions properly before the
    Court of Appeals that the petition or response claims were
    erroneously decided by that court.” After we accepted review
    in this case, we determined that several of the issues argued
    by AFM on review were neither raised in its Court of Appeals
    briefs nor adequately developed in the trial court. In partic-
    ular, AFM did not raise any issue in the Court of Appeals as
    to whether there were genuine issues of material fact con-
    cerning the exclusions on which it bore the burden of proof,
    or whether the trial court erred in concluding that AFM
    failed to satisfy its burden of proof regarding exclusions.
    Accordingly, we do not address arguments that AFM makes
    on review concerning policy exclusions. AFM also makes a
    very brief argument that it was denied both discovery and
    due process by the manner in which the garnishment pro-
    ceeding was conducted. Because AFM failed to raise, assign
    error to the pertinent rulings, and adequately develop those
    arguments, we do not address them.
    In addition, we note that, although the parties and
    amici curiae have discussed to some extent the “all sums”
    and “pro rata” rules of allocation of damages among mul-
    tiple insurers, AFM’s arguments in this case, both in the
    trial court and in the Court of Appeals, have never been
    about how, if damage occurred over multiple policy periods
    Cite as 
    360 Or 341
     (2016)	353
    involving different insurers, such damages should be appor-
    tioned. Rather, AFM maintained that FountainCourt failed
    to meet its burden of proof and that, as a result, AFM was
    not liable at all.6 Thus, although we briefly discuss the “all
    sums” rule below, see 360 Or at 366 n 11, this case does not
    present the opportunity to decide whether the “all sums” or
    “pro rata” approach should be used in this context.
    Accordingly, as previously stated, we reframe the
    issues before us on review as follows: (1) Did the trial court
    properly resolve the issues raised in the garnishment pro-
    ceeding in a manner that comported with this court’s case
    law concerning an insurer’s duty to defend and right to lit-
    igate coverage issues, and did not implicate AFM’s right to
    a jury trial; and (2) did the trial court correctly interpret
    the insurance policies to conclude that coverage had been
    triggered under the policies and that AFM was liable to
    FountainCourt in light of FountainCourt’s verdict against
    Sideco in the underlying negligence case?
    To answer those questions, we first examine some of
    the basic principles of insurance law and garnishment law,
    and then, we turn to the question whether the trial court
    properly concluded that AFM was liable under the policies
    at issue.
    II. ANALYSIS
    A.  Preliminary Issues
    We begin with several preliminary issues regard-
    ing how this insurance dispute came to be litigated in a
    garnishment proceeding separate from, but in conjunction
    with, a negligence action. We first discuss, as an initial mat-
    ter, why insurance coverage issues generally are litigated
    separately from the liability of the insured, and then turn to
    issues related to garnishment proceedings.
    6
    We further note that AFM, in its questions presented on review, referred
    to the present case as a “mixed coverage” case, which it described as “involving
    some damage that is payable by an insurer and some damage that is not.” That
    framing of the issue implicitly assumes that an “all sums” approach is imper-
    missible under Oregon law. See 360 Or at 366 n 11. Because, as explained below,
    AFM did not raise or litigate the applicability of the “all sums” approach below,
    we do not reach it.
    354	   FountainCourt Homeowners v. FountainCourt Develop.
    1.  Duty to defend and right to separately litigate cover-
    age issues
    An insurer has a duty to defend its insured in an
    action against the insured if the action involves any claim
    stated against the insured that could impose liability for
    conduct covered by the policy. Ledford v. Gutoski, 
    319 Or 397
    , 399, 877 P2d 80 (1994). That duty remains even if the
    complaint also alleges conduct or damages that would not
    fall within the policy’s coverage. 
    Id. at 399-40
    . Thus, an
    insurer’s duty to defend its insured in an action is not nec-
    essarily co-extensive with its duty to indemnify its insured
    when the insured does not prevail in that action. For that
    reason, insurers defend under a reservation of rights, in
    order to separately litigate coverage issues, as explained
    below. That is, situations may arise in which the insured’s
    liability in the underlying action, despite being potentially
    covered under the policy in light of the pleadings, may not
    ultimately be covered by the policy. The insurer’s and the
    insured’s interests may align perfectly in the underlying
    proceeding in which the insurer has a duty to defend, in
    that both share the interest in establishing that the insured
    is not liable to the plaintiff. Beyond that point, however,
    the interests may diverge, particularly in cases in which
    the insured’s liability may be based on conduct that is not
    covered, on occurrences outside of the scope of the policy,
    or on specifics embodied in policy exclusions, among other
    reasons. Of course, the insured would prefer that, if found
    liable, the damages be covered by insurance, whereas the
    insurer would prefer that if its insured is found liable, the
    liability is for something that is not within the policy’s cov-
    erage. Thus, the potential for a conflict of interest often is
    present in situations in which an insurer is obligated to
    defend its insured.
    When an insured is represented by attorneys pro-
    vided by the insurer, the insured relinquishes control over
    the defense of the claim, and a fiduciary relationship is
    created between the insured and insurer that exists inde-
    pendent of the insurance contract. Georgetown Realty v.
    The Home Ins. Co., 
    313 Or 97
    , 111, 831 P2d 7 (1992). In
    this situation, insurers are required “to exercise due dil-
    igence in the defense of claims against insureds.” Maine
    Cite as 
    360 Or 341
     (2016)	355
    Bonding v. Centennial Ins. Co., 
    298 Or 514
    , 518, 693 P2d
    1296 (1985). As a practical matter, this means that an
    insurer that defends its insured in an underlying action in
    a way that is detrimental to the insured in order to favor
    the insurer may become liable to the insured in tort. See,
    e.g., Goddard v. Farmers Ins. Co., 
    344 Or 232
    , 179 P3d 645
    (2008) (upholding punitive damage award against insurer
    based on insurer’s bad faith in litigating underlying action
    against insured).
    The tension created by situations where the insureds’
    and insurers’ interests are not perfectly aligned has been
    the subject of much litigation over the years, culminating
    in the rule of law announced in Ferguson v. Birmingham
    Fire Ins., 
    254 Or 496
    , 460 P2d 342 (1969). In Ferguson, the
    insured was sued for timber trespass and tendered defense
    to the insurer. The insurer offered to defend under a res-
    ervation of rights, but the insured declined. At trial in the
    underlying action, the jury found that the trespass had
    occurred, but that it was not intentional. The insured then
    brought an action against the insurer seeking to recover the
    damages as well as the costs of defending the underlying
    action. 
    Id. at 500-01
    . The insurer maintained that it had no
    duty to defend because a policy exclusion applied. This court
    explained that the insurer did have a duty to defend under
    these circumstances, and discussed the potential difficulties
    faced by an insurer in such a situation:
    “If the insurer assumes the defense in the face of the
    insured’s refusal to accede to insurer’s request for a res-
    ervation of rights, it is said that the insurer ‘waives’ or is
    ‘estopped’ to assert the defense of noncoverage. And if the
    insurer, in order to avoid the loss of its right to question
    coverage, rejects the tender of the defense, it loses the ben-
    efits that accrue from being represented by its own counsel
    who ordinarily is experienced in the defense of such actions.
    And if it guesses wrong on the question of coverage, it will
    be required to pay the judgment and the costs of defense.
    Thus the insurer is forced to choose between two alterna-
    tives either of which exposes it to a possible detriment or
    loss.
    “What is the justification for imposing this dilemma
    upon the insurer? Where there is a conflict of interest
    between the insurer and insured and the judgment in the
    356	   FountainCourt Homeowners v. FountainCourt Develop.
    action against the insured can be relied upon as an estoppel
    by judgment in a subsequent action on the issue of cover-
    age, the control of the action by the insurer could adversely
    affect the insured if the judgment was based upon conduct
    of the insured not falling within the coverage of the policy.
    Likewise, the insurer could be adversely affected by a judg-
    ment based upon conduct for which there is coverage. But we
    see no reason for applying the rule of estoppel by judgment
    in such cases. The judgment should operate as an estop-
    pel only where the interests of the insurer and insured
    in defending the original action are identical—not where
    there is a conflict of interests. If the judgment in the orig-
    inal action is not binding upon the insurer or insured in a
    subsequent action on the issue of coverage, there would be
    no conflict of interests between the insurer and the insured
    in the sense that the insurer could gain any advantage in
    the original action which would accrue to it in a subsequent
    action in which coverage is in issue.”
    
    Id. at 509-11
     (emphasis added; footnotes omitted). In sum,
    an insurer is not precluded (collaterally estopped) by the
    judgment in the underlying action from taking a position
    in a later coverage proceeding that the damages awarded
    in the underlying action are not covered by the insurance
    policy. See Paxton-Mitchell Co. v. Royal Indemnity Co., 
    279 Or 607
    , 613 n 2, 569 P2d 581 (1977) (so noting).
    Relying on Ferguson, AFM argues that its interests
    and Sideco’s interests were in conflict with respect to cov-
    erage, and therefore it was “not bound by the facts of the
    underlying lawsuit,” and “not bound by the factual findings
    assumed within the judgment.” It argues therefore that “the
    nature of Sideco’s liability” was a genuine issue of material
    fact that could not be decided based on the verdict in the
    underlying case, but was subject to being litigated anew in
    the subsequent proceeding. AFM contends that the trial
    court, in effect, precluded it from litigating Sideco’s liability
    as a factual issue at the garnishment proceeding and thus
    collaterally estopped AFM, in a manner inconsistent with
    the holding of Ferguson. Although we agree with AFM’s ini-
    tial proposition—that there were potential conflicts between
    AFM and Sideco and that the rule from Ferguson does have
    application here—AFM misapprehends how the rule from
    Ferguson applies in this case.
    Cite as 
    360 Or 341
     (2016)	357
    At the center of this dispute is a provision in the
    insurance contract stating that AFM “will pay those sums
    that the insured becomes legally obligated to pay as damages
    because of * * * ‘property damage’ to which this insurance
    applies.” (Emphasis added.) What the insured is legally
    obligated to pay as damages can be determined only by
    reference to the underlying action, which determined the
    insured’s legal obligation to pay damages. Thus, in the sub-
    sequent proceeding, the insurer is not, as AFM contends,
    entitled to second-guess or retry “the nature of Sideco’s lia-
    bility.” (Emphasis added.) That is not, however, because it is
    “collaterally estopped” from doing so. Rather, that is because
    the subsequent proceeding requires the court to evaluate—
    as a matter of contract law—what, precisely, the insured
    has become legally obligated to pay as damages in the prior
    proceeding, in order to determine whether the policy covers
    those damages. In other words, an insurer cannot, in a sub-
    sequent proceeding, retry its insured’s liability, or alter the
    nature of the damages awarded in that proceeding.
    Ferguson does not suggest otherwise. Ferguson
    indicates that an insurer is not obligated to pay a judgment
    entered against its insured if it has not had an opportunity
    to litigate, on its own behalf and not as a part of its duty
    to defend the insured in the underlying proceeding, cover-
    age issues such as whether an exclusion applies or whether
    the damages awarded are otherwise covered by the policy.7
    7
    As the parties recognize, an attorney attempting to do both at the same
    time in the same proceeding faces not only practical but potential ethical dilem-
    mas. See, e.g., Oregon Formal Ethics Opinion No. 2005-121 (opining that attorney
    hired by insurer to defend insured under reservation of rights could not ethically
    move for dismissal of only claim covered by insurance); cf. Eastham v. Oregon
    Auto. Ins. Co., 
    273 Or 600
    , 607, 540 P2d 364 (1975) (in settlement negotiations in
    this context, insurer must give equal consideration to the conflicting interests of
    itself and its insured).
    AFM argues on review that both the trial court and Court of Appeals deci-
    sion in the present case impermissibly gave preclusive effect to the verdict in the
    underlying case and, in essence, would require an attorney defending an insured
    to try coverage issues in the underlying proceeding in a manner that is ethically
    problematic. We disagree. The coverage issues were not, and could not have been,
    tried in the underlying negligence proceeding. That the damages awarded in the
    underlying proceeding needed to be considered in determining coverage in the
    later proceeding does not in any way suggest that the coverage issues could or
    should have been litigated in the underlying proceeding, or that AFM was pre-
    cluded from making any legal argument or presenting any evidence on a genuine
    issue of material fact in the garnishment proceeding.
    358	   FountainCourt Homeowners v. FountainCourt Develop.
    Those matters may be litigated in a subsequent proceed-
    ing, but what is subsequently litigated is constrained by the
    nature of the contractual obligations between the insurer
    and the insured which, as noted above, here involves evalua-
    tion of what “the insured [became] legally obligated to pay as
    damages” in the underlying proceeding. Contrary to AFM’s
    suggestions, what the insured became legally obligated to
    pay as damages in the underlying proceeding did not pres-
    ent a “genuine issue of material fact” for a jury to decide in
    the later proceeding. Rather, what the insured had become
    obligated to pay as damages and whether the insurer ulti-
    mately was liable under its policy presented questions of law
    for the court to determine by reference to (a) the contract and
    (b) the judgment and record in the underlying proceeding.
    That is not to say, however, that the judgment in
    the underlying case had any preclusive effect as to factual
    issues and legal issues relating to insurance coverage, which
    brings us to our next topic of discussion—how such determi-
    nations are to be made in subsequent proceedings concern-
    ing insurance coverage.
    2.  Garnishment as a method for determining insurance
    obligations
    There are numerous ways that insurance litigation
    after an insured has become liable for damages may come
    before the courts. Often either the insurer or the insured
    seeks a declaratory judgment. See, e.g., ZRZ Realty v.
    Beneficial Fire and Casualty Ins., 
    349 Or 117
    , 241 P3d 710
    (2010), on recons, 
    349 Or 657
    , 249 P3d 111 (2011). Sometimes
    such issues are raised by way of equitable claims for contri-
    bution. See, e.g., Firemen’s Ins. v. St. Paul Fire Ins., 
    243 Or 10
    , 411 P2d 271 (1966). Sometimes, as in this case, the issue
    is raised by way of garnishment. See, e.g., A&T Siding, Inc. v.
    Capitol Specialty Ins. Corp., 
    358 Or 32
    , 359 P3d 1178 (2015).
    ORS 18.352 provides:
    “Whenever a judgment debtor has a policy of insurance
    covering liability, or indemnity for any injury or damage
    to person or property, which injury or damage constituted
    the cause of action in which the judgment was rendered,
    the amount covered by the policy of insurance shall be
    Cite as 
    360 Or 341
     (2016)	359
    subject to attachment upon the execution issued upon the
    judgment.”
    ORS 18.710(1) provides that “[a] debtor’s challenge to a gar-
    nishment shall be adjudicated in a summary manner at a
    hearing before the court with authority over the writ of gar-
    nishment.” ORS 18.782 allows for the calling of witnesses at
    the hearing, and provides that “[t]he proceedings against a
    garnishee shall be tried by the court as upon the trial of an
    issue of law between a plaintiff and defendant.” (Emphasis
    added.)
    Thus, the garnishment statutes contemplate that
    issues such as those presented here will be resolved by a
    trial to the court. AFM argues that because a garnishment
    proceeding is an action at law rather than in equity, a party
    is entitled to a jury trial on fact issues. See Or Const, Art I,
    § 17 (“In all civil cases the right of Trial by Jury shall remain
    inviolate.”); Or Const, Art VII (Amended), § 3 (“In actions
    at law, where the value in controversy shall exceed $750,
    the right of trial by jury shall be preserved[.]”); Horton v.
    OHSU, 
    359 Or 168
    , 173, 376 P3d 998 (2016) (“Article I, sec-
    tion 17, guarantees a jury trial in those cases in which the
    right to a jury trial was customary at the time the Oregon
    Constitution was adopted and in cases of like nature.”).
    On review, AFM makes a sweeping argument
    that there were triable issues of fact relating to (1) what
    damages were caused by an “occurrence” under the poli-
    cies and occurred during the policy periods; (2) whether the
    damages in the underlying case were “property damage”
    under the policies; and (3) whether various exclusions, such
    as the multi-unit exclusion and “one or more of the busi-
    ness risk exclusions,” barred coverage. The first two issues,
    as litigated in this case, involve questions of law concern-
    ing the interpretation of the insurance policies in light of
    undisputed facts; we discuss them below. As for the third,
    concerning the applicability of various exclusions, although
    we agree in general that the determination of matters per-
    taining to exclusions often will require trying issues of
    fact, we need not resolve in the present case whether the
    trial court erroneously failed to submit any such issues to
    a jury. As noted above, AFM failed to assign error or make
    360	   FountainCourt Homeowners v. FountainCourt Develop.
    any arguments in the Court of Appeals concerning factual
    issues relating to any policy exclusions, see 360 Or at 352,
    so no questions concerning policy exclusions were “properly
    before the Court of Appeals,” ORAP 9.20, and therefore
    they are not properly before this court. Thus, in light of our
    discussions below concerning the meaning of various pol-
    icy provisions and triggers of coverage, and in light of the
    limitation of the issue before us on review, we have no need
    to address whether the trial court erred in denying AFM’s
    motion for a jury trial.
    B.  Coverage Issues
    As noted, AFM raises issues concerning whether
    the trial court properly allocated the burden of proof,
    whether FountainCourt proved that the underlying judg-
    ment against Sideco was “property damage,” whether
    FountainCourt proved an “occurrence” that triggered cov-
    erage, and whether the damages were properly allocated to
    AFM. We turn first to burdens of proof.
    1.  Burdens of proof
    With respect to burdens of proof, the law is settled.
    As we noted in ZRZ:
    “[T]he insured * * * has the burden to prove coverage while
    the insurer * * * has the burden to prove an exclusion from
    coverage. Compare Stanford v. American Guaranty Life Ins.
    Co., 
    280 Or 525
    , 527, 571 P2d 909 (1977) (insurer has the
    burden to prove an exclusion), with Lewis v. Aetna Insurance
    Co., 
    264 Or 314
    , 316, 505 P2d 914 (1973) (insured has the
    burden to prove coverage).”
    349 Or at 127. There is no ambiguity in how that rule
    applies in the present case. Both “property damage” and
    “occurrence,” as used in the policy, relate to coverage, and
    thus AFM is correct that FountainCourt, standing in the
    shoes of the insured, had the burden of demonstrating both
    that Sideco had become “legally obligated to pay as dam-
    ages because of * * * ‘property damage,’ ” and that there
    had been an “occurrence,” defined by the policy. AFM, by
    contrast, had the burden as to issues relating to its policy
    exclusions.
    Cite as 
    360 Or 341
     (2016)	361
    2.  Property damage
    AFM contends that FountainCourt failed to estab-
    lish that Sideco had become obliged to pay damages because
    of “property damage.” The gist of AFM’s argument seems to
    be that, under Ferguson, 254 Or at 510-11, the parties were
    not bound by the facts found by the jury in the underlying
    trial, and at most, FountainCourt established a mere possi-
    bility that the damages found by the jury were for “property
    damage” as defined in the insurance policies. In particu-
    lar, AFM argues that the damages found by the jury in the
    underlying proceeding are not “property damage” as defined
    in the insurance policy, because the damages in the under-
    lying proceeding could have included the costs of repairing
    “defective work” by Sideco, and “defective work” does not
    constitute property damage (citing Wyoming Sawmills v.
    Transportation Ins. Co., 
    282 Or 401
    , 578 P2d 1253 (1978)).
    As explained above, Ferguson does not require a
    court resolving an insurance coverage issue to disregard
    the nature of the damage award in the underlying action.
    Indeed, given that the coverage generally is based on the
    “sums the insured becomes legally obligated to pay as dam-
    ages” because of property damage, the damage award in the
    underlying proceeding is a key to resolution of the coverage
    issue. 360 Or at 357. The policies at issue here define prop-
    erty damage as “[p]hysical injury to tangible property.” In
    this case, as noted, the only claim that went to the jury with
    respect to Sideco concerned property damage, and the jury
    was instructed that FountainCourt was required to “prove
    physical damage to their property,” and that the “measure of
    damages for partial destruction of real property is the rea-
    sonable cost of repairing damaged property.” 360 Or at 346
    (emphasis added). The jury was not instructed that it could
    award damages for “defective work”—it was instructed it
    could award damages for “physical damage.” Contrary to
    AFM’s urging, Wyoming Sawmills does not stand for the
    proposition that actual physical damage to property is not
    covered under an insurance policy merely because it may
    be associated with defective workmanship by an insured.
    Rather, that case addressed whether “intangible” damage
    such as “depreciation in value” fell within the meaning of
    362	     FountainCourt Homeowners v. FountainCourt Develop.
    “physical damage” as used in an insurance policy. 
    282 Or at 406
    . This court held that “in the absence of a showing that
    any physical damage was caused to the rest of the building
    by the defective studs and that the labor cost was for the rec-
    tification of any such damage, plaintiff cannot recover.” 
    Id. at 406-07
    . Here, in contrast to Wyoming Sawmills, the jury
    awarded damages based on Sideco’s negligence that caused
    physical damage to the FountainCourt buildings. See 
    id. at 407
     (“We do not hold that if damage was occasioned to any
    part of the building [other than the defective studs] such
    damage is not covered.”). This case was tried to the jury
    on the theory that Sideco’s negligence had caused physical
    damage to property. We find no significant legal distinction
    between physical damage to property as awarded in the
    underlying case and “physical injury to tangible property”
    as used in the insurance contracts.8 The trial court did not
    err in determining, as a matter of law based on interpre-
    tation of the insurance contracts, that the sum that Sideco
    became legally obligated to pay as damages in the underly-
    ing action were for “property damage.”
    3.  Trigger of coverage
    That brings us to AFM’s argument that Fountain-
    Court was obligated to, but could not, establish that the
    damage was caused by an “occurrence” within the periods
    covered by the AFM policies. As noted, both parties took the
    position at the garnishment hearing that the water damage
    at issue here is cumulative, and that it was not possible to
    determine how much of it had occurred during what pol-
    icy periods. We do not understand AFM to be contending
    otherwise on appeal. Rather, it argues that Oregon follows
    an injury-in-fact rule for the triggering of coverage, that
    FountainCourt failed to prove “based on facts in evidence
    at the trial” the amount of damages that occurred between
    May 1, 2004 and May 1, 2006, when the AFM policies were
    in effect, and that therefore coverage was not triggered. As
    8
    Much of AFM’s argument in regard to “property damage” appears to be
    based more on what is in the exclusions found in its policies, rather than the defi-
    nitions. However, as noted, the insurer bears the burden of establishing that an
    exclusion applies, and AFM neither assigned error nor argued on appeal that the
    trial court had erred in concluding that it failed to meet its burden with respect
    to exclusions.
    Cite as 
    360 Or 341
     (2016)	363
    explained below, AFM is incorrect about how trigger-of-
    coverage issues are analyzed in cases such as this involving
    continuous damage that occurs over the course of multiple
    policy periods.
    In St. Paul Fire v. McCormick & Baxter Creosoting,
    
    324 Or 184
    , 923 P2d 1200 (1996), this court addressed
    trigger-of-coverage issues concerning a number of general
    comprehensive liability insurance policies, in the context of
    deciding an insurance dispute about environmental dam-
    age to real property that occurred over the course of several
    decades. Several of those policies used the terms “occur” and
    “occurrence” in a manner similar to the policy at issue here.
    
    Id. at 194-95, 197-99, 200
    . The damage in that case had
    been discovered in the 1970s, and the question presented
    was whether coverage was triggered under any or all of the
    pre-1970 insurance policies. The insurers argued that cov-
    erage was not triggered until the damage was discovered.
    This court rejected that argument:
    “The operative phrase in the trigger clauses contained
    in the caused-by-accident policies is ‘during the policy
    period.’ The common meaning of ‘during’ is ‘at some point
    in the course of.’ Webster’s Third New Int’l Dictionary 703
    (unabridged ed 1993). The trigger clause states that, if an
    insurable event—i.e., an accident—happens at some point
    in the course of the policy period, then that event is cov-
    ered. There is no wording in the pertinent policies that
    would support the insurers’ reading, and the insurers that
    issued the caused-by-accident policies point to none.
    “* * * * *
    “[Various policies from the 1960s] contain definitions
    of ‘occurrence’ that provide that an occurrence has taken
    place if there is ‘direct injury to or destruction of tangible
    property during the policy period.’ (Emphasis added.) Those
    words are unambiguous. If property is injured during the
    policy period, there has been an ‘occurrence,’ and coverage
    under the policy is triggered.”

     (emphasis in original). The court stated that
    “[t]he policies do not make an ‘occurrence’ depend on the
    fixing of financial responsibility, or damages.” 
    Id.
     The court
    therefore concluded that those insurers were not entitled to
    364	     FountainCourt Homeowners v. FountainCourt Develop.
    summary judgment on the ground that their policies had
    not been “triggered.” 
    Id. at 202
    . Implicit in this court’s hold-
    ing was that, although the damage at issue there had begun
    to occur before the policies were in effect, and continued to
    occur after the policies were no longer in effect, coverage
    under those policies was nonetheless “triggered” because
    the damage was ongoing during the policy periods.
    That conclusion comports not only with the policy
    language at issue in St. Paul Fire,9 but also with the deci-
    sions of most other courts that have considered the issue,
    as well as treatises discussing this topic. See, e.g., Allan D.
    Windt, Insurance Claims and Disputes § 11.4, 11-102 (6th ed
    2013) (“The correct answer, and the rule in the vast majority
    of the courts to have addressed the issue, is that coverage
    is triggered from the date of the first latent injury/damage
    and continues to be triggered at least until the date the
    injury/damage first becomes manifest.”); id. § 11.4 at 11-107
    (“[W]hen there is an ongoing process of property damage or
    bodily injury, every policy period in effect during the ongoing
    damage/injury process provides coverage.”); cf. Lee R. Russ
    and Thomas F. Segalla, 15 Couch on Insurance § 220:26 (3d
    ed 2005) (“in continuous trigger cases, insurers face liabil-
    ity up to their respective per-occurrence limits for separate
    occurrence for each triggered policy year in which they were
    on the risk”).
    AFM does not seriously dispute that there was proof
    that some property damage did occur during the time its
    policies were in effect. Indeed, both parties provided expert
    opinion that supported that conclusion. Rather, AFM’s posi-
    tion has been that, because FountainCourt had the burden
    of demonstrating an “occurrence” during the policy period,
    it necessarily was required to demonstrate the amount of
    damage that occurred during the policy period. That posi-
    tion is inconsistent with our holding in St. Paul Fire, and
    it appears to be at odds with the provision in the policies
    indicating that property damage not known to the insured
    9
    The policies at issue here similarly support such an interpretation. See, e.g.,
    360 Or at 349 (“ ‘[P]roperty damage’ which occurs during the policy period and
    was not, prior to the policy period, known to have occurred by any insured * * *
    includes any continuation, change or resumption of that ‘bodily injury’ or ‘prop-
    erty damage’ after the end of the policy period.”).

    prior to the policy period “includes any continuation, change
    or resumption of that ‘bodily injury’ or ‘property damage’
    after the end of the policy period.” 360 Or at 349 (emphasis
    added).10 In sum, no genuine issue of material fact needed
    to be resolved at the garnishment proceeding concerning
    whether at least some property damage occurred when the
    AFM policies were in effect. The court correctly rejected,
    as a matter of law, AFM’s arguments that FountainCourt
    was required to prove the precise amount of damages that
    occurred during the policy period in order to demonstrate
    that there had been an “occurrence” that triggered coverage
    under the policies.
    4.  Allocation of liability among multiple insurers
    Inherent in many of AFM’s arguments in this court
    is an assumption that, because it insured Sideco for only
    a portion of the time that the damage was occurring, it
    cannot be held liable for the entire amount that Sideco is
    legally obliged to pay to FountainCourt. As described above,
    AFM’s primary position throughout this litigation has
    been that it has no liability at all. However, AFM also sug-
    gests at least implicitly in its arguments to this court that
    any liability that it has should not be for the full amount
    of damages that Sideco owes to FountainCourt. Whatever
    the abstract merits of AFM’s assumption might be, the fact
    is that AFM did not argue at the garnishment proceeding
    about how, if it were found to be liable for damages awarded
    to FountainCourt against Sideco, such damages should be
    allocated among policy periods and/or multiple potentially
    responsible parties. It did not argue in the trial court, or
    in the Court of Appeals, that it might be liable for some but
    not all of the damages. In this court, as noted above, see
    10
    AFM’s position also is inconsistent with the following observation from
    Windt 3 Insurance Claims and Disputes § 11.4 at 11-107-08, that
    “when there is an ongoing process of property damage or bodily injury, every
    policy period in effect during the ongoing injury process provides coverage.
    The burden should be on the insured to prove that there was, in fact, such
    injury/damage during the policy period. The insured should also have the
    burden of quantifying such injury/damage, unless (i) the issue is how to allo-
    cate the injury/damage among policies covering consecutive policy periods, or
    (ii) quantification is impossible.”
    (Emphasis added; citations omitted.)
    366	     FountainCourt Homeowners v. FountainCourt Develop.
    360 Or at 353 n 6, AFM described this case as “involving
    some damage that is payable by an insurer and some dam-
    age that is not.” That framing of the issue led to the parties
    and various amici raising questions and making arguments
    about how liability should be allocated in situations where
    multiple insurers may be potentially liable.
    In situations such as this, where it is not possible,
    as a matter of proof, to quantify how much continuous dam-
    age took place during specific policy periods, courts have
    resolved the question by reference to policy provisions, or
    when a policy does not contain specific provisions about
    allocation among insurers, by adopting a judicially created
    method of allocation. “Because in these types of cases it is
    virtually impossible to allocate to each policy the liability for
    injuries occurring only within its policy period, the courts
    are left with the nettlesome problem of how to allocate dam-
    ages among the policies.” Russ and Segalla, 15 Couch on
    Insurance § 220:25. Most of the courts that have addressed
    this problem have taken one of two possible approaches:
    One is often referred to as the “all sums” approach, and
    the other is often called the “pro rata” approach.11 AFM has
    11
    The “all sums” approach is exemplified by Keene Corp. v. Insurance Co. of
    North America, 667 F2d 1034, 1047 (DC Cir 1981), which involved asbestos expo-
    sure over a long period of time:
    “The policies at issue in this case provide that the insurance company
    will pay on behalf of [its insured] ‘all sums’ that [the insured] becomes legally
    obligated to pay as damages because of bodily injury during the policy period.
    * * * [When the insured was] held liable for an asbestos-related disease, only
    part of the disease will have developed during any single policy period. The
    rest of the development may have occurred during another policy period or
    during a period in which [the insured] had no insurance. The issue that
    arises is whether an insurer is liable in full, or in part, for [the insured’s]
    liability once coverage is triggered. We conclude that the insurer is liable in
    full, subject to [policy provisions relating to other insurance].”
    The court in that case further noted: “There is nothing in the policies that pro-
    vides for a reduction of the insured’s liability if an injury occurs only in part
    during a policy period.” Id. at 1048. The court observed that the policies “do
    not distinguish between injury that is caused by occurrences that continue to
    transpire over a long period of time and more common types of injury. Nor do
    the policies provide that ‘injury’ must occur entirely during the policy period for
    full indemnity to be provided.” Id. at 1049 (footnote omitted). See also Russ and
    Segalla, 15 Couch on Insurance § 220.27 (citing cases following the “all sums”
    approach).
    The “pro rata” approach, by contrast, takes into account the span of time
    over which the damage occurred, then allocates to each insurer a portion of the
    liability based on how much of that time that insurer’s policy was in effect. This

    360 Or 341
     (2016)	367
    never taken the position in this litigation that Oregon courts
    should eschew the “all sums” approach in favor of a “pro rata”
    approach, or vice versa. Rather, it has taken the position
    that neither approach is consistent with Oregon law because
    in this circumstance, an insured is unable to demonstrate
    that there is coverage at all. That is, AFM’s position has
    been that, in cases in which damage occurs over a number
    of years, and spans different insurance policies, and no way
    exists to pinpoint what amount of damage occurred at what
    point in time, the insured cannot establish that coverage
    has been triggered. As we explained above, 360 Or at 364-
    65, we disagree with the premise of that argument, i.e., that
    coverage was not triggered if it is impossible for an insured
    to demonstrate how much damage occurred during a policy
    period.
    It appears that the trial court implicitly did apply
    some variation of the “all sums” approach in this case. That
    is, the trial court concluded that FountainCourt had estab-
    lished that the AFM policies had been triggered—property
    damage had occurred during the AFM policy periods. It also
    concluded that the Clarendon policy had been triggered, but
    that Clarendon had met its burden to establish that it none-
    theless was not liable because the damages fell within a pol-
    icy exclusion. By entering judgment against AFM for the
    entire unpaid amount of the underlying judgment against
    Sideco, the court implicitly concluded that AFM was respon-
    sible for the entire amount and not a prorated amount,
    although some of the damage necessarily had occurred
    when the Clarendon policy was in effect, given the court’s
    conclusion that that policy was triggered. The trial court’s
    conclusion appears to be consistent with Cascade Corp. v.
    approach was explained in Boston Gas Co. v. Century Indem. Co., 454 Mass 337,
    361, 
    910 NE2d 290
     (2009), as consistent with the “occurrence” definitions in the
    policies at issue in that case, and superior, to the “all sums” approach as a matter
    of policy, because the “all sums” approach does not solve the problem of allocation
    among insurers, but merely postpones it, leaving it to be decided in a subsequent
    action for contribution. The “pro rata” approach is premised on the notion that an
    insurer should be responsible for the amount of damage that took place during
    its policy period. See generally Windt, 2 Insurance Claims and Disputes § 6.47
    (“If * * * the covered damages cannot, as a practical matter, be allocated to one
    particular policy period as opposed to another, the damages should ultimately be
    allocated among the solvent insurers based upon the period of time each insurer
    covered the ongoing damage.”).

    206 Or App 1
    , 8-10, 135 P3d
    450 (2006), rev dismissed, 
    342 Or 645
     (2007). In that case,
    the Court of Appeals, in a somewhat analogous context con-
    cerning liability of multiple excess insurers, indicated that,
    while a pro rata approach was suitable in determining allo-
    cation among insurers in contribution actions, it did not pro-
    vide a basis for reducing the insurer’s liability to its insured.
    AFM did not raise any issue in the Court of Appeals
    in the present case that the trial court erred in taking that
    approach. Nor did the Court of Appeals decide any such
    issue, but in fact, specifically determined that it “need not
    reach that question.” FountainCourt, 264 Or App at 488
    n 12. Thus, while the “all sums” rule was implicated here
    in that the trial court’s judgment appears to have embodied
    that approach, the propriety of the trial court doing so was
    not preserved for our review, and we decline to address it.12
    III. CONCLUSION
    To summarize, no genuine issue of material fact was
    presented by the parties at the garnishment hearing about
    whether some property damage to FountainCourt’s build-
    ings occurred during the AFM’s policy periods due to Sideco’s
    negligence. The “genuine issues of material fact” that AFM
    urged in the trial court concerned (1) what damage occurred
    during the policy periods, and (2) whether “property dam-
    age” under the policies differed in some legally significant
    way from the property damage for which Sideco had been
    held liable in the underlying proceeding. As to the first ques-
    tion, AFM’s casting of the timing-of-damage issue as a gen-
    uine issue of material fact on which FountainCourt bore the
    burden of proof was based on AFM’s mischaracterization of
    the policy as barring coverage of any damages that fell out-
    side of the policy periods, and on its erroneous assumption
    that an insured in this situation is required to demonstrate
    12
    We emphasize that the application of an “all sums” or “pro rata” approach
    to determining liability is not simply an abstract question of insurance law, but
    often is a matter that must be determined based on the language of the insurance
    policies at issue, when such issues are properly raised by the parties. Neither
    party in the present case has made any argument about how specific policy pro-
    visions, such as the provision quoted above concerning “continuation” of property
    damage “after the end of the policy period,” might affect such an analysis. 360 Or

    the precise amount of damage that occurred at a given time
    in order to establish that there has been an “occurrence”
    that triggered coverage. As explained above, the legal prem-
    ises of both of those arguments are flawed. As to the second
    question, the trial court properly addressed it as a question
    of law, requiring it to interpret the policies’ provisions in
    light of the judgment and record from the underlying pro-
    ceeding. Given the manner in which AFM chose to litigate
    this case at the garnishment proceeding and in the Court of
    Appeals, and given the limited scope of the issues before us
    on review, we conclude that the trial court and the Court of
    Appeals correctly rejected AFM’s arguments as a matter of
    law.
    The decision of the Court of Appeals is affirmed.
    The supplemental judgment for garnishment is affirmed.
    The supplemental judgment awarding attorney fees, costs,
    and disbursements is reversed as to the attorney fee award
    and is otherwise affirmed.
