    This case is an insurance coverage dispute between Plaintiff-Appellant Black &
    Veatch Corporation (“B&V”) and Defendants-Appellees Aspen Insurance (UK) Ltd. and
    Lloyd’s Syndicate 2003 (collectively, “Aspen”). The issue is whether Aspen must
    reimburse B&V for the costs B&V incurred due to damaged equipment that its
    subcontractor constructed at power plants in Ohio and Indiana. The district court held
    that Aspen need not pay B&V’s claim under its commercial general liability (“CGL”)
    insurance policy (the “Policy”) because B&V’s expenses arose from property damages
    that were not covered “occurrences” under the Policy. Because the only damages
    involved here were to B&V’s own work product arising from its subcontractor’s faulty
    workmanship, the court concluded that the Policy did not provide coverage and granted
    Aspen’s motion for partial summary judgment. B&V appealed.
    The district court had diversity jurisdiction under 28 U.S.C. § 1332. We exercise
    appellate jurisdiction under 28 U.S.C. § 1291. Because we predict that the New York
    Court of Appeals would decide that the damages here constitute an “occurrence” under
    the Policy, we vacate the court’s summary judgment decision and remand for further
    consideration in light of this opinion.
    I. BACKGROUND
    A. Factual Background
    B&V is a global engineering, consulting, and construction company. A portion of
    its work involves “EPC contracts.” “EPC” stands for engineering, procurement, and
    construction. Under an EPC contract, B&V delivers services under a single contract. It
    supervises the project and typically subcontracts most—if not all—of the actual
    procurement and construction work.
    1. Underlying Claim Against B&V for Property Damages
    2
    In 2005, B&V entered into EPC contracts with American Electric Power Service
    Corporation (“AEP”) to engineer, procure, and construct several jet bubbling reactors
    (“JBRs”), which eliminate contaminants from the exhaust emitted by coal-fired power
    plants.1 For at least seven of these JBRs, which were located at four different power
    plants in Ohio and Indiana, B&V subcontracted the engineering and construction of the
    internal components to Midwest Towers, Inc. (“MTI”). Deficiencies in the components
    procured by MTI and constructed by MTI’s subcontractors caused internal components
    of the JBRs to deform, crack, and sometimes collapse.
    After work on three of the JBRs was completed, and while construction of four
    others was ongoing, AEP alerted B&V to the property damage arising from MTI’s
    negligent construction. AEP and B&V entered into settlement agreements resolving their
    disputes relating to the JBRs at issue here. Under the agreements, B&V was obligated to
    pay more than $225 million in costs associated with repairing and replacing the internal
    components of the seven JBRs.
    2. The B&V-Aspen CGL Policy
    B&V had obtained several insurance policies to cover its work on these JBRs.2
    Zurich American Insurance Company (“Zurich”) provided the primary layer of coverage
    1
    AEP entered the EPC contracts in its own capacity and as an agent for other
    power companies. We refer to these companies collectively as “AEP.”
    2
    B&V entered the Lloyd’s of London (“Lloyd’s”) insurance market to negotiate
    an insurance policy that would cover its potential liability as an EPC contractor. Lloyd’s
    is not an insurance company but rather a specialist insurance market within which
    multiple financial backers come together to pool and spread risk. U.S.-based insurance
    brokers cannot directly access the Lloyd’s insurance market, so B&V’s brokers were
    3
    for up to $4 million for damage to completed work. Under the CGL Policy at issue here,
    Aspen provides the first layer of coverage for claims exceeding the Zurich policy’s
    limits.3 The Policy limits coverage up to $25 million per occurrence and $25 million in
    the aggregate. The structure of the Policy consists of (a) a basic insuring agreement
    defining the general scope of coverage, (b) exclusions from coverage, and (c) exceptions
    to the exclusions.
    a. Basic insuring agreement
    The Policy’s basic insuring agreement reads:
    We [the Insurer] will pay on behalf of the “Insured” those sums in excess of
    the [liability limit provided by other insurance policies] which the
    “Insured” by reason of liability imposed by law, or assumed by the
    “Insured” under contract prior to the “Occurrence”, shall become legally
    obligated to pay as damages for:
    (a) “Bodily Injury” or “Property Damage” . . . caused by an
    “Occurrence” . . .
    ROA, Vol. 1 at 68.
    It defines the key terms as follows:
     Occurrence: “an accident, including continuous or repeated exposure to
    substantially the same general harmful conditions, that results in ‘Bodily Injury’ or
    ‘Property Damage’ that is not expected or not intended by the ‘Insured’.” 
    Id. at 71.
     Property Damage: “physical injury to tangible property of a ‘Third Party’,
    including all resulting loss of use of that property of a ‘Third Party’ . . . .” 
    Id. at 72.
    required to use an intermediary known as a “wholesale” broker to negotiate the insurance
    policy.
    3
    Liberty Mutual Insurance Europe (UK), Ltd. provided the second layer of excess
    coverage.
    4
     Third Party: “any company, entity, or human being other than an ‘Insured’ or
    other than a subsidiary, owned or controlled company or entity of an ‘Insured’.”
    
    Id. In sum,
    the Policy covers damages arising from an “occurrence,” which includes
    an accident causing damage to the property of a third party. It does not define “accident.”
    b. Exclusions
    Following the basic insuring agreement, the Policy then scales back coverage
    through several exclusions, two of which are relevant here. The first, known as the
    “Your Work” exclusion, or “Exclusion F,” excludes coverage for property damage to
    B&V’s own completed work. It reads:
    This policy does not apply to . . . ‘Property Damage’ to ‘Your Work’
    arising out of it or any part of it and included in the ‘Products/Completed
    Operations Hazard.’
    
    Id. at 74.
    “Products/Completed Operations Hazard” refers to property damage or
    bodily injury arising out of completed work. 
    Id. at 72.
    “Your Work” is defined as
    “work operations performed by you or on your behalf” by a subcontractor. 
    Id. at 73.
    References to B&V’s own work thus include work done by B&V as well as
    MTI.
    The second exclusion, known as “Endorsement 4,” excludes coverage for
    property damage to the “particular part of real property” that B&V or its
    subcontractors were working on when the damage occurred. 
    Id. at 83.
    This
    exclusion pertains only to ongoing, rather than completed, work.
    c. Exception
    5
    The “Your Work” exclusion is subject to an exception, thus restoring some
    coverage. The exception provides that “[the ‘Your Work’ exclusion] does not
    apply if the damaged work or the work out of which the damage arises was
    performed on [B&V’s] behalf by a subcontractor.” 
    Id. at 74
    (emphasis added).
    In other words, the Policy does not cover property damage to B&V’s own
    completed work unless the damage arises from faulty construction performed by a
    subcontractor. We refer to this as the “subcontractor exception.”
    B. Procedural History
    B&V submitted claims to its liability insurers for a portion of the $225 million it
    cost to repair and replace the defective components. After B&V recovered $3.5 million
    from Zurich, its primary insurer,4 it sought excess recovery from Aspen. Aspen denied
    coverage. B&V sued Aspen in federal district court for breach of contract and
    declaratory judgment as to B&V’s rights under the Policy. B&V sought coverage for
    approximately $72 million, a portion of the total loss. On cross-motions for partial
    summary judgment on the coverage issue, the court sided with Aspen, holding that
    damage arising from construction defects was not an “occurrence” under the Policy
    unless the damage occurred to something other than B&V’s own work product. Because
    4
    Zurich paid its full completed operations aggregate limit of $4 million, less the
    $500,000 deductible, for the damages incurred.
    6
    the damages here occurred only to the B&V’s own work product—the JBRs—the court
    found they were not covered.5 This appeal followed.
    II. DISCUSSION
    We begin with our standard of review. We then discuss standard-form CGL
    policies, relevant New York law regarding CGL policies and insurance contract
    interpretation, and the relevance of our decision in Greystone Construction, Inc. v.
    National Fire & Marine Insurance Co., 
    661 F.3d 1272
    , 1289 (10th Cir. 2011), which
    addressed a similar coverage issue. Interpreting the Policy in light of applicable law, we
    conclude the district court erred in determining that a subcontractor’s faulty workmanship
    causing damage to an insured’s own work can never be an “occurrence.”
    The threshold and primary question is whether the New York Court of Appeals,
    the highest court in the State of New York, would hold that the Policy’s basic insuring
    agreement covers the property damage to the JBRs as an “occurrence.” 
    Greystone, 661 F.3d at 1282
    (explaining that in the absence of a decision by the highest court of a state,
    we follow a decision by an intermediate court unless we find a convincing reason to do
    otherwise). We conclude the damages constitute an “occurrence” under the Policy
    because they were accidental and harmed a third party’s property. Further, a contrary
    reading would render the “subcontractor exception” and “Endorsement 4” mere
    surplusage, in violation of New York law. The subcontractor exception does not create
    coverage. Only the basic insuring agreement can do that. But the subcontractor
    5
    As described above, the Policy defines B&V’s “work” as work performed by
    B&V or by a subcontractor on B&V’s behalf. See ROA, Vol. 1 at 73.
    7
    exception informs our understanding of an “occurrence” based on New York’s rule that
    we should read the insurance policy as a whole and avoid interpretations that render
    provisions meaningless. Applying these analytical tools, we predict the New York Court
    of Appeals would conclude that the damages at issue here are “occurrences” under the
    Policy’s basic insuring agreement.
    New York state court decisions have not resolved whether subcontractor damages
    can be deemed an “occurrence” under a CGL policy containing a subcontractor
    exception. The district court and Aspen contend that New York courts have answered
    this question, relying heavily on George A. Fuller Co. v. United States Fidelity and
    Guaranty Co., 
    613 N.Y.S.2d 152
    , 153 (N.Y. App. Div. 1994), and other intermediate
    appellate court decisions. But they ignore a critical distinction between Fuller and the
    present case. The court in Fuller considered a CGL policy that excluded coverage for
    damages to an insured’s own work, whether the damage was caused by the contractor or
    a subcontractor. Unsurprisingly, Fuller concluded that the particular policy in that case
    was not intended to insure against faulty workmanship in the work product itself. 
    Id. at 155.
    The decision offered no analysis regarding policies, such as the one here,
    explicitly stating that damages to an insured’s own work are covered when a
    subcontractor, rather than the contractor itself, performed the faulty workmanship. In
    other words, Fuller does not stand for the proposition that damages caused by a
    subcontractor’s faulty workmanship can never constitute an “occurrence” under a CGL
    policy. For this and other reasons more fully explained below, Fuller and the cases that
    8
    rely on it are inapt and distinguishable. We thus reverse the district court’s holding that
    denied coverage and remand for further proceedings in light of this opinion.6
    A. Standard of Review
    We review summary judgment de novo and apply the same legal standard as the
    district court. Cornhusker Cas. Co. v. Skaj, 
    786 F.3d 842
    , 849 (10th Cir. 2015). A court
    “shall grant summary judgment if the movant shows that there is no genuine dispute as to
    any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ.
    P. 56(a); see also 
    Cornhusker, 786 F.3d at 850
    . We also review legal questions de novo,
    including the district court’s interpretation of New York law, which the parties agree
    governs here. See Bird v. West Valley City, 
    832 F.3d 1188
    , 1199 (10th Cir. 2016).
    “Where the state’s highest court has not addressed the issue presented, the federal court
    must determine what decision the state court would make if faced with the same facts and
    issue.” 
    Id. (quotations omitted).
    B. Standard-Form CGL Policies
    A CGL policy covers the costs a policyholder incurs due to property damage and
    bodily injury. See Donald S. Malecki, Commercial General Liability Coverage Guide,
    The National Underwriter Company at 9 (10th ed. 2013) (“CGL Coverage Guide”). In
    this section, we describe: (1) the structure and (2) the history and development of CGL
    policies.
    6
    The district court held only that the damages at issue here could not constitute a
    coverage-triggering “occurrence” under the Policy, so it did not proceed to the next step
    of determining the effect of any Policy exclusions or exceptions to the exclusions. It
    should do so on remand.
    9
    1. Structure of Standard-Form CGL Policies
    Most CGL policies are drafted using standardized forms developed by the
    Insurance Services Office, Inc. (“ISO”), an association of insurance carriers. See
    Hartford Fire Ins. Co. v. California, 
    509 U.S. 764
    , 772 (1993). ISO maintains a large
    portfolio of “endorsements,” language that can be used to amend a standard CGL policy
    to suit the needs of the insured or insurer. CGL Coverage Guide at 177. Policies that
    deviate from the standard CGL policy forms and endorsements are called “manuscript”
    policies. See Gabarick v. Laurin Mar. (Am.), Inc., 
    650 F.3d 545
    , 554 (5th Cir. 2011)
    (explaining that manuscript policies are tailored to the unique coverage needs of the
    insured); Bangert Bros. Const. Co. v. Americas Ins. Co., 
    66 F.3d 338
    , at *2 (10th Cir.
    1995) (unpublished table decision).
    The basic structure of standard CGL policies mirrors the three-part structure of the
    B&V-Aspen Policy described above. CGL policies begin with the “basic insuring
    agreement” defining the initial scope of coverage. An insured cannot recover for
    property damages that fall outside this definition. The basic insuring agreement is then
    subject to exclusions, which narrow the scope of coverage. The exclusions are then
    subject to exceptions, which restore coverage—but only to the extent coverage was
    initially included in the basic insuring agreement.
    a. Basic insuring agreement
    CGL policies begin with a broad grant of coverage in the basic insuring
    agreement. An “occurrence” triggers coverage. CGL policies—including the Policy
    here—define an “occurrence” as “an accident, including continuous or repeated exposure
    10
    to substantially the same general harmful conditions.” CGL Coverage Guide, App. K:
    2013 Claims-Made Form, at 558. Neither the standard CGL policy nor the Policy in this
    case defines the term “accident.”
    b. Exclusions—and exceptions to exclusions
    i. Overview
    The scope of the basic insuring agreement for damages caused by an “occurrence”
    is then limited by any exclusions from coverage that the parties include in the policy. In
    other words, a CGL policy starts with a broad grant of coverage for damages arising from
    an “occurrence.” Exclusions narrow the scope of coverage. For example, CGL policies
    generally exclude coverage for damages that the insurer “expected or intended.” See 
    id. at 543.
    Exceptions to the exclusions may restore—but do not create—coverage.
    ii. The “Your Work” exclusion and “subcontractor exception”
    One of the standard-form CGL exclusions and its corresponding exception is
    identical to the “Your Work” exclusion and “subcontractor exception” in the Policy here.
    See CGL Coverage Guide, App. K: 2013 Claims-Made Form, at 547.7 In the standard-
    form CGL policy, this exclusion is listed as “Exclusion L.” 
    Id. In the
    Policy, it is listed
    as “Exclusion F.” For consistency, we refer to this provision as the “Your Work”
    exclusion.
    7
    Under this exclusion, a CGL insurance policy does not apply to “‘[p]roperty
    damage’ to ‘your work’ arising out of it or any part of it and included in the ‘products-
    completed operations hazard.’” CGL Coverage Guide, App. K: 2013 Claims-Made
    Form, at 547.
    11
    As in the Policy and the standard-form CGL policy, the “subcontractor exception”
    follows the “Your Work” exclusion. This exception provides that the “Your Work”
    exclusion “does not apply if the damaged work or the work out of which the damage
    arises was performed on your behalf by a subcontractor.” 
    Id. 2. History
    and Development of CGL Policies
    The history and development of CGL policies guide our interpretation of the
    Policy at issue here.8 The standard-form CGL policy has undergone several revisions
    since the first one was promulgated in 1940. The 1973 standard-form CGL policy
    precluded coverage for property damage to an insured’s own completed work, regardless
    of whether the damages were caused by work completed by the contractor or “on [its]
    behalf” by a subcontractor. CGL Coverage Guide, App. A: 1973 CGL Form (excluding
    coverage for “property damage to work performed by or on behalf of the named insured”
    (emphasis added)); see Christopher C. French, Revisiting Construction Defects as
    “Occurrences” Under CGL Insurance Policies, 19 U. Pa. J. Bus. L. 101, 107 (2016)
    (“French”). The 1973 version of the “Your Work” exclusion did not contain a
    subcontractor exception. Instead, subcontractor-caused damage was considered a risk
    inherent to the construction business and explicitly excluded from coverage in CGL
    policies.
    By 1976, general contractors, who were increasingly reliant on subcontractors’
    work, had become dissatisfied with the lack of CGL policy coverage when the general
    8
    As explained above, the key policy language at issue in this case is materially
    identical to the language used in standard-form CGL policies.
    12
    contractor was not directly responsible for defective work. See Steven Plitt et al., 9A
    Couch on Ins. § 129:19 (3rd ed. 2017) (“Plitt”). In response, the 1976 standard-form
    CGL policy eliminated the phrase “or on behalf of” from the “Your Work” exclusion.
    The policy thus broadened coverage by no longer excluding damages arising from faulty
    subcontractor work. Contractors could pay a higher premium to add additional coverage
    for property damage arising from completed work that had been performed by
    subcontractors. Id.; see also French at 107. This optional coverage provision was known
    as the “Broad Form Property Damage Endorsement” (“BFPD Endorsement”) and
    provided that the policy only excluded “property damage to completed work performed
    by the named insured.” CGL Coverage Guide, App. A: Broad Form Endorsement,
    at 295; see also Plitt at § 129:19. “Unfortunately, the courts [have failed to] recognize
    the importance of this language change.” Philip L. Bruner, et al., § 11:259 Completed
    operations work exclusion—Generally, Bruner & O’Connor Construction Law (2017)
    (“Bruner”).
    In 1986, the ISO attempted to clear up this confusion by expressly stating in the
    standard-form CGL policy that the “Your Work” exclusion does not apply “if the
    damaged work . . . was performed . . . by a subcontractor.” See CGL Coverage Guide,
    App. B: 1986 Occurrence Form, at 299; see also Bruner at § 11:259. Since then, the ISO
    standard-form CGL policy has contained materially identical language to the “Your
    Work” exclusion and “subcontractor exception” language that appears in the Policy here.
    The ISO explained that this revision was intended to clarify that CGL policies “cover[ed]
    . . . damage to, or caused by, a subcontractor’s work after the insured’s operations are
    13
    completed.” Ins. Servs. Office, Inc., Commercial General Liability Program
    Instructions Pamphlet, Circular No. GL-86-204 (July 15, 1986) (“ISO 1986 Circular”)
    (emphasis added). The “Your Work” exclusion, in other words, is inapplicable when
    damage arises from a subcontractor’s faulty workmanship.
    As one commentator explained, by 1986, insurance carriers and policyholders
    agreed that CGL policies should cover defective construction claims “so long as the
    allegedly defective work had been performed by a subcontractor rather than the
    policyholder itself.” French at 108 (quoting 2 Jeffrey W. Stempel, Stempel on Insurance
    Contracts § 14.13[D], at 14-224.8 (3d ed. Supp. 2007) (“Stempel”)). “This resulted both
    because of the demands of the policyholder community (which wanted this sort of
    coverage) and the view of insurers that the CGL was a more attractive product that could
    be better sold if it contained this coverage.” 
    Id. (quoting Stempel
    at 14-224.8).
    In the context of ongoing work, the standard-form CGL policy excludes coverage
    for property damage to “[t]hat particular part of real property on which you or any
    contractors or subcontractors working . . . on your behalf are performing operations, if the
    ‘property damage’ arises out of those operations.” CGL Coverage Guide, App. B: 1986
    Occurrence Form, at 298; see also ISO 1986 Circular (explaining that the policy covers
    “damage caused by faulty workmanship to . . . parts of work in progress” other than what
    the contractor or subcontractors were working on). In other words, the policy excludes
    damage to “that particular part” of the project upon which the insured’s operations were
    being performed at the time the damage occurred, but it covers damage to property other
    than “that particular part.” This is the current understanding of the phrase “that particular
    14
    part” in the insurance industry today. Scott C. Turner, “That particular part” limitation,
    Insurance Coverage of Construction Disputes § 29:7 (2d ed. 2017).
    In sum, since 1986, the standard-form CGL policy has covered the cost of
    property damage to (1) completed projects, when the damage is due to subcontractors’
    faulty work, and (2) ongoing work, when faulty workmanship damages property other
    than “that particular part” on which the contractor or subcontractor was working at the
    time the damage occurred. Again, this assumes that a CGL policy’s basic insuring
    agreement provides coverage for such damages in the first instance.
    C. New York Law Interpreting CGL Policies
    1. Definition of “Accident”
    Neither the standard-form CGL policy nor the Policy here defines the term
    “accident.” The New York Court of Appeals has held that damages are accidental so
    long as they are “unexpected and unintentional.” Cont’l Cas. Co. v. Rapid-American
    Corp., 
    609 N.E.2d 506
    , 510 (N.Y. 1993). These terms are to be construed as barring
    coverage “only when the insured intended the damages.” 
    Id. (emphases added).
    The fact
    that an insured might have foreseen the possibility that its subcontractor would build a
    defective product does not render the resulting damages intentional—and thus not
    covered—under the policy. See 
    id. (acknowledging that
    a policyholder might take a
    “calculated risk” without expecting or intending the resulting damages).
    2. General Principles of Contract Interpretation
    New York courts recognize that “[a]n insurance agreement is subject to principles
    of contract interpretation.” Burlington Ins. Co. v. NYC Transit Auth., 
    79 N.E.3d 477
    , 481
    15
    (N.Y. 2017) (quotations omitted). “[I]n determining a dispute over insurance coverage,
    [courts] first look to the language of the policy.” Roman Catholic Diocese of Brooklyn v.
    Nat’l Union Fire Ins. Co. of Pittsburgh, 
    991 N.E.2d 666
    , 671 (N.Y. 2013) (quotations
    omitted). In doing so, they must “construe the [CGL] policy in a way that affords a fair
    meaning to all of the language employed by the parties in the contract and leaves no
    provision without force and effect.” 
    Id. at 671-72
    (quotations omitted) (applying the rule
    in determining whether separate incidents constituted one or multiple “occurrences”
    under a CGL insurance policy). The New York Court of Appeals recently reiterated this
    rule in In re Viking Pump, Inc., explaining that an interpretation of a contract that renders
    a provision surplusage is one “that cannot be countenanced under [New York courts’]
    principles of contract interpretation.” 
    52 N.E.3d 1144
    , 1154 (N.Y. 2016) (citing Roman
    Catholic 
    Diocese, 991 N.E.2d at 666
    ).
    D. Relevance of Greystone
    The parties discuss this court’s Greystone decision in their briefs, and we wish to
    address its relevance to this case. In Greystone, the issue was “whether property damage
    caused by a subcontractor’s faulty workmanship is an ‘occurrence’ for purposes of a
    [CGL] 
    policy.” 661 F.3d at 1276
    . Homeowners had sued a general contractor, asserting
    defective construction by a subcontractor that had installed the foundation of the home.
    The claim was premised on the theory that the house was damaged due to a
    subcontractor’s negligent design and construction of the home’s soil-drainage and
    structural elements, which exposed the foundation to shifting soils. 
    Id. Over time,
    soil
    expansion caused the foundation to shift, resulting in extensive damage to the upper
    16
    living area. 
    Id. The contractor
    sought coverage from its insurer. 
    Id. We determined
    that
    some of the damages constituted an “occurrence” under the policy.
    Although Colorado law applied, a significant portion of the opinion was not tied to
    Colorado law. Interpreting the policy, which was materially the same as the Policy here,
    this court followed the strong trend of state supreme court case decisions interpreting the
    term “occurrence” to encompass accidental damage to property resulting from poor
    workmanship. 
    Id. at 1282-83
    (collecting cases). The panel also relied on general
    principles of contract interpretation—such as construing the policy in accordance with its
    plain meaning and avoiding surplusage—which are the same principles under New York
    law and equally applicable here. In this regard, Greystone is relevant and helpful to our
    analysis in this case.9
    9
    Greystone, however, is inapplicable here to the extent it relied on Colorado law
    that varies from New York law. Colorado, for example, defines “accident” more
    narrowly—damages are accidental when they are “unanticipated” or “unforeseeable.”
    See 
    Greystone, 661 F.3d at 1285
    (citing Union Ins. Co. v. Hottenstein, 
    83 P.3d 1196
    ,
    1201 (Colo. App. 2003)). Because a contractor’s “obligation to repair defective work is
    neither unexpected nor unforeseen,” damage to the contractor’s work arising from
    defective construction was not accidental. 
    Id. at 1286.
    Applying Colorado law,
    Greystone concluded that such damages—i.e., to the home’s soil-drainage and structural
    elements—were not a covered “occurrence” under the policy. 
    Id. “Conversely, when
    a
    subcontractor’s faulty workmanship causes unexpected property damage to otherwise
    nondefective portions of the builder’s work, the policies provide coverage.” 
    Id. (emphasis added).
    Greystone defined “nondefective property” as “property that has been
    damaged as a result of poor workmanship.” 
    Id. at 1284.
    The damage to the home’s
    upper living areas was thus a covered “occurrence.”
    New York law, by contrast, provides that damages are non-accidental “only when
    the insured intended the damages.” Cont’l Cas. 
    Co., 609 N.E.2d at 510
    (emphases
    added). Thus, even if damages were anticipated or foreseeable, they would still be
    accidental—unless the contractor intended that they occur. Greystone’s definition of
    “accident,” and its resulting distinction between defective and nondefective work, is thus
    linked to Colorado law that differs from New York’s broader construction of the term
    17
    E. Analysis
    The issue is whether the New York Court of Appeals would find that B&V’s
    policy with Aspen covers a portion of the payments that B&V made to AEP to repair and
    replace the damaged JBRs. Our analysis concludes that it would, based on (1) the
    Policy’s language and New York’s rule against surplusage, (2) the history and
    development of CGL policies, (3) the trend among state supreme courts, and (4) the lack
    of New York appellate court decisions precluding a finding of “occurrence” under this
    particular Policy.10
    1. Damage to the JBRs Was an “Occurrence” Under the Policy
    We first address whether, under New York contract law, B&V is seeking payment
    from Aspen for a covered “occurrence”—the first step necessary for obtaining coverage
    under a CGL insurance policy. See 
    Greystone, 661 F.3d at 1281
    . CGL insurance
    policies are contracts, see Roman Catholic 
    Diocese, 991 N.E.2d at 671
    , which New York
    courts interpret in light of their plain meaning, Callahan v. Carey, 
    909 N.E.2d 1229
    , 1233
    (N.Y. 2009). We start with the Policy terms and definitions, which are materially
    “accident.” In any event, counsel for B&V said at oral argument that “all of the damage
    [B&V] seek[s] in this case is to nondefective work,” see Oral Arg. at 2:41-46, so any
    distinction between defective and nondefective work is immaterial here.
    10
    The dissent contends that in determining how the New York Court of Appeals
    would decide this case, “we must apply relevant New York case law,” Dissent at 3. We
    agree. The dissent overlooks that this opinion draws from cases decided by the New
    York Court of Appeals to support its analysis, including cases defining “accident” for
    purposes of determining CGL policy coverage and providing principles of contract
    interpretation to understand CGL policy terms. For example, in Viking Pump, the New
    York Court of Appeals reaffirmed the key principle that contracts must be read to avoid
    rendering any provision surplusage.
    18
    identical to the ISO’s standard-form CGL policy. Under the Policy, an “occurrence” is
    an “accident . . . that results in ‘Bodily Injury’ or ‘Property Damage’ that is not expected
    or not intended by the ‘Insured.’” An occurrence triggers coverage. We examine each
    part of this definition.
    a. Accidental damages
    The Policy does not define “accident,” but the New York Court of Appeals has
    explained that a CGL policy covers damages only when they were “unexpected and
    unintentional.” Cont’l Cas. 
    Co., 609 N.E.2d at 510
    (holding that these terms are to be
    construed narrowly as barring coverage “only when the insured intended the damages”);
    see also Consol. Edison Co. of N.Y. v. Allstate Ins. Co., 
    774 N.E.2d 687
    , 692 (N.Y. 2002)
    (“Insurance policies generally require ‘fortuity’ and thus implicitly exclude coverage for
    intended or expected harms.”). A policyholder might take a “calculated risk”—such as
    hiring a subcontractor—without “expecting” damages to occur. See Cont’l Cas. 
    Co., 609 N.E.2d at 510
    . “[I]n fact, people often seek insurance for just such circumstances.” 
    Id. Whether or
    not B&V took a “calculated risk” by delegating work on the JBRs to a
    subcontractor, Aspen does not argue—nor does the record support—that B&V “expected
    or intended” MTI or any other subcontractor to cause damage. Nor is there evidence that
    B&V increased the likelihood of such damages through reckless cost-saving or other
    measures. See 
    Fuller, 613 N.Y.S.2d at 155
    (finding no “occurrence” where damages
    19
    arose from “intentional cost-saving or negligent acts”). Thus, the damages at issue here
    satisfy the Policy’s accidental requirement.11
    b. Property damage to a third party
    The Policy covers costs arising from property damage.12 “Property Damage” is
    defined as “physical injury to tangible property of a ‘Third Party.’” ROA, Vol. 1 at 72.
    A “Third Party” is defined as “any company, entity, or human being other than an
    ‘Insured.’” 
    Id. The damage
    to the JBRs was physical injury to tangible property. Aspen
    argues, however, that the Policy designates AEP—the energy company that hired B&V to
    construct the JBRs—as an “Additional Insured,” and thus AEP cannot be a third party.
    See Aplee. Br. at 45 (citing ROA, Vol. 7 at 1311). This argument fails.
    Under the Policy, an “Insured” is defined as any entity listed as a “Named
    Insured” or designated as an “Additional Insured.” The Policy lists B&V as the “Named
    11
    We acknowledge that the definition of “occurrence” in the Policy at issue here
    differs slightly from the definition in ISO’s standard-form CGL policy, but this difference
    is not substantive and is immaterial to our analysis. The Policy here defines “occurrence”
    as an accident that was not “expected or intended.” The “expected or intended” language
    is part of the definition of “occurrence.” Until 1986, standard-form CGL policies also
    included the “expected or intended” language as part of the definition of “occurrence.”
    See CGL Coverage Guide, App. A: GL Policy Jacket Provisions, at 287. But because
    courts had been treating the language as an exclusion, in 1986 the ISO formally moved
    the language out of the “occurrence” definition and into the exclusions section of CGL
    policies. See 
    id. App. B:
    1986 Occurrence Form, at 297; see also French at 106. “This
    move, however, did not change the analysis of whether there has been an occurrence.”
    French at 106.
    12
    The Policy also covers “bodily injury.” See ROA, Vol. 1 at 81.
    20
    Insured.”13 ROA, Vol. 1 at 63. Under Endorsement 33, AEP is designated as an
    “Additional Insured,” thereby adding AEP to B&V’s existing insurance policy. See 
    id. at 114.
    Granting one party additional insured status on another’s CGL policy is a
    “common risk-shifting technique” used in construction contracts. Samir Mehta,
    Additional Insured Status in Construction Contracts and Moral Hazard, 3 Conn. Ins. L.J.
    169, 170 (1997). But it does not mean the Policy precludes coverage of the damages
    at issue here.
    First, AEP is an “Additional Insured” only with respect to liability for property
    damage “arising out of operations performed by the Named Insured.” ROA, Vol. 1 at
    114 (emphasis added). But here the work performed by a subcontractor (MTI), not by
    the “Named Insured” (B&V), caused the damages.14
    Second, Endorsement 33 contains a “separation of insureds” condition, which
    provides that the Policy “applies separately to each Insured against whom claim is made
    or suit is brought.” 
    Id. Its purpose
    is to preserve coverage for damage claims made by
    one insured (here, AEP) against another (B&V). See West Am. Ins. Co. v. AV&S, 
    145 F.3d 1224
    , 1227 (10th Cir. 1998) (providing that under a “separation of insureds”
    condition, each insured is “entitled to have the [p]olicy construed as to it as if the [p]olicy
    were issued only as to it alone”); see also Greaves v. Pub. Serv. Mut. Ins. Co., 155
    13
    Endorsement 34 adds additional entities to the “Named Insured” list (e.g., Black
    & Veatch Europe Inc., Black & Veatch (UK) Limited, and Black & Veatch Thailand
    Limited). AEP is not listed.
    14
    Endorsement 34 does not add MTI as another “named insured,” and thus the
    endorsement is immaterial to our analysis.
    
    21 N.E.2d 390
    , 392 (N.Y. 1959) (same). In other words, when AEP claimed damages
    against B&V, the separation of insureds clause rendered AEP a third party with respect to
    its claims for property damage against B&V. This understanding of the Policy aligns
    with common sense: The principle risk B&V faced as an EPC contractor, and thus a
    main reason for obtaining CGL insurance, was the potential for claims alleging damages
    made by the property owner—AEP.
    c. Rule against surplusage
    The foregoing discussion establishes that the property damage to the JBRs
    constitutes an “occurrence” under the Policy. Concluding otherwise would violate the
    New York Court of Appeal’s rule against surplusage—a point the dissent ignores. In
    other words, Aspen’s interpretation of “occurrence” as excluding the damages at issue
    here would render several Policy provisions meaningless in violation of New York
    contract interpretation rules. See Roman Catholic 
    Diocese, 991 N.E.2d at 671
    .
    i. The “Your Work” exclusion and “subcontractor exception”
    The “Your Work” exclusion (listed as “Exclusion F”) in the Policy excludes
    coverage for property damage to the insured’s own completed work. ROA, Vol. 1 at 74
    (providing that the Policy “does not apply to . . . ‘Property Damage’ to ‘Your Work’
    arising out of it or any part of it and included in the ‘Products/Completed Operations
    Hazard’”). The next sentence, however, provides an exception—the “subcontractor
    exception”—restoring some coverage. 
    Id. It states
    that the “Your Work” exclusion
    “does not apply if the damaged work or the work out of which the damage arises was
    performed on your behalf by a subcontractor.” 
    Id. 22 Aspen’s
    interpretation of “occurrence” would render these provisions superfluous
    in violation of New York law requiring that CGL policies be construed “in a way that
    affords a fair meaning to all of the language . . . in the contract and leaves no provision
    without force and effect.” Roman Catholic 
    Diocese, 991 N.E.2d at 671
    -72 (quotations
    omitted) (applying rule against surplusage to CGL policies); see Viking 
    Pump, 52 N.E.3d at 1154
    . It would be redundant to say the Policy does not cover property damage to
    B&V’s own work (as stated in the “Your Work” exclusion) if the definition of
    “occurrence” categorically and preemptively precludes coverage for such damages in the
    first instance.15
    Similarly, there would be no reason for the Policy to state that it covers damages
    to the insured’s work when “the damaged work . . . was performed . . . by a
    subcontractor” if the basic insuring agreement does not encompass these damages. See
    ROA, Vol. 1 at 74; see also 
    Greystone, 661 F.3d at 1289
    (“[T]he only way [the ‘Your
    Work’ exclusion and ‘subcontractor exception’ have] effect is if we find that physical
    injury caused by poor workmanship . . . may be an occurrence under standard CGL
    policies.”); see also Lamar Homes, Inc. v. Mid-Continent Cas. Co., 
    242 S.W.3d 1
    , 12
    (Tex. 2007) (“By incorporating the subcontractor exception into the ‘your-work’
    exclusion, the insurance industry specifically contemplated coverage for property damage
    caused by a subcontractor’s defective performance.”); Great Am. Ins. Co. v. Woodside
    Homes Corp., 
    448 F. Supp. 2d 1275
    , 1282 (D. Utah 2006) (“[I]t is undeniable that
    15
    Again, the Policy defines “Your Work” as work performed either by B&V or its
    subcontractors. The JBRs are thus B&V’s “work” under the Policy, even though MTI
    engineered and constructed them.
    23
    excluding faulty subcontractor work from the definition of ‘occurrence’ would reduce the
    operation of the subcontractor exception so drastically that the language would virtually
    cease to be of any meaningful effect.”)
    Aspen argues B&V cannot rely on the “subcontractor exception” because—as an
    exception to an exclusion—it cannot create coverage that does not already exist under the
    Policy’s basic insuring agreement. But as we have explained, the “subcontractor
    exception” does not create coverage, the Policy’s basic insuring agreement does. Its
    definition of “occurrence” encompasses damage to B&V’s own work arising from faulty
    subcontractor workmanship. The “Your Work” exclusion and “subcontractor exception,”
    which would lose their meaning under Aspen’s definition of “occurrence,” only provide
    further evidence that our reading of the Policy is correct. Neither Aspen nor the district
    court adequately squares their position with New York’s rule against surplusage.
    ii. “Endorsement 4”
    Aspen’s interpretation of an “occurrence” would also render “Endorsement 4”
    surplusage. As described above, “Endorsement 4” pertains to ongoing work and excludes
    coverage for property damage to “that particular part of real property” on which B&V or
    its subcontractors were actively working. See ROA, Vol. 1 at 83 (emphasis added). If
    faulty workmanship resulting in damage to B&V’s own work could never trigger
    coverage as an “occurrence,” this part of “Endorsement 4” would be meaningless. In
    other words, there would be no reason for “Endorsement 4” to exclude coverage only for
    damage to a “particular part” of the JBRs if the Policy could never cover damage to the
    insured’s work in the first instance.
    24
    ****
    In sum, the property damages at issue were caused by an “occurrence,” as that
    term is defined in the Policy, because (1) B&V neither intended nor expected that its
    subcontractor would perform faulty work, so the damages were accidental, (2) the
    damages involved physical harm to the property of a third party, and (3) a contrary
    conclusion would render various Policy provisions meaningless in violation of New
    York’s rule against surplusage.
    2. History of CGL Policies Supports Finding of “Occurrence”
    The history of standard-form CGL policies further demonstrates that the Policy
    covers the costs arising from the property damages here. As described in greater detail
    above, early versions of the “Your Work” exclusion precluded coverage for property
    damages due to the faulty work of the general contractor or its subcontractor. By 1976,
    general contractors had become more reliant on subcontractors and were frustrated by the
    lack of coverage offered by CGL policies for damages caused by subcontractor’s work.
    Plitt § 129:19. In response, the ISO narrowed the exclusion by removing the reference to
    subcontractors and thus implicitly extending coverage for contractors when the property
    damage alleged was caused by the work of subcontractors. 
    Id. After courts
    failed to recognize the importance of this language change, the ISO
    attempted to clarify its 1976 revisions by adding the “subcontractor exception” to
    standard-form CGL policies. See id.; Bruner § 11:259; French at 108 (explaining this
    change was driven by agreement between contractors and insurers that CGL policies
    should cover defective construction claims “so long as the allegedly defective work had
    25
    been performed by a subcontractor rather than the policyholder itself” (quoting Stempel
    at § 14.13[D]) (emphasis added)). Aspen and the cases it cites, which we discuss below,
    ignore these changing dynamics and ISO’s own explanation that the 1986 changes
    clarified that CGL policies covered “damage to, or caused by, a subcontractor’s work
    after the insured’s operations are completed.” ISO 1986 Circular (emphases added).
    3. Trend Among State Supreme Courts Supports Finding of “Occurrence”
    State supreme courts that have considered the issue since 2012 have reached “near
    unanimity” that “construction defects can constitute occurrences and contractors have
    coverage under CGL policies at least for the unexpected damage caused by defective
    workmanship done by subcontractors.” French at 122-23 (emphasis added); see Thomas
    E. Miller, et al., § 6.02 Third Party Coverage, Handling Construction Defect Claims:
    Western States 123 (2018) (“The majority of state supreme courts that have decided
    whether inadvertent faulty workmanship is an accidental ‘occurrence’ potentially covered
    under the CGL policy have ruled that it can be an ‘occurrence.’”) (“Miller”). According
    to Miller, 21 state supreme courts have adopted this position, with some of these courts
    reversing their own contrary precedent. Miller at § 6.02; see, e.g., Cherrington v. Erie
    Ins. Prop. & Cas. Co., 
    745 S.E.2d 508
    , 417 (W. Va. 2013) (reversing court’s precedent
    precluding faulty workmanship from constituting an “occurrence,” finding it “outdated”).
    Before 2012, state supreme courts adopted “wildly” different approaches. See
    Miller at § 6.02. A minority of states—14, according to Miller—had determined that
    “defective workmanship (i.e., construction defects) do[es] not constitute an
    ‘occurrence.’” 
    Id. But at
    least one, New Jersey, has since migrated to the majority view
    26
    that faulty workmanship by a subcontractor can be an occurrence under CGL insurance
    policies. See Cypress Point Condo. Ass’n v. Adria Towers, LLC, 
    143 A.3d 273
    , 287 (N.J.
    2016). Miller also notes that some of these state decisions finding no “occurrence” have
    been superseded by local statutes requiring CGL policies issued in those states to include
    coverage for defective workmanship. Miller at § 6.02; see, e.g., Essex Ins. v. Holder, 
    261 S.W.3d 456
    , 460 (Ark. 2008) (holding that defective construction resulting in damage
    only to the insured’s work product itself is foreseeable and thus not an “occurrence”
    under the CGL policy), superseded by statute, Ark. Code Ann. § 23-79-155(a)(2) (2011)
    (requiring CGL insurance policies to define “occurrence” to include “[p]roperty damage
    or bodily injury resulting from faulty workmanship”).16
    4. New York Intermediate Appellate Court Decisions Do Not Preclude Coverage
    The Policy language and other state supreme court decisions support a finding of
    “occurrence.” Would the New York Court of Appeals agree? We think it would, though
    16
    The dissent criticizes the majority opinion for “‘turning to the law of other
    jurisdictions’ to determine what the New York Court of Appeals ‘would probably’ decide
    in this case.” Dissent at 4 (quoting Lehman Bros. v. Schein, 
    416 U.S. 386
    , 389 (1976))
    (brackets omitted). But Lehman does not preclude us from considering other
    jurisdictions in attempting to predict how the New York Court of Appeals would decide
    this case. Moreover, we are aware of no rule that would prevent the New York Court of
    Appeals from considering—as it has before and as we have here—“how CGL policies are
    generally drafted, scholarly sources, and persuasive authority from courts applying the
    law of other jurisdictions,” 
    id. at 4,
    to assist in determining an issue on which it has not
    ruled. See, e.g., Great N. Ins. Co. v. Mount Vernon Fire Ins. Co., 
    708 N.E.2d 167
    , 169
    (N.Y. 1996) (discussing standard form CGL policy); Cont’l Cas. Co. v. Rapid-American
    Corp., 
    609 N.E.2d 506
    , 508, 510-11 (N.Y. 1993) (same); Davis v. S. Nassau Cmty.
    Hosp., 
    46 N.E.3d 614
    , 622 (N.Y. 2015) (relying on legal treatise); Viking 
    Pump, 52 N.E.3d at 1152
    (relying on law review articles); People v. Leonard, 
    970 N.E.2d 856
    , 860
    (N.Y. 2012) (relying on supreme court decisions from other states); In re D., 
    261 N.E.2d 627
    , 630 (N.Y. 1970) (same).
    27
    it has yet to address this question. Where, as here, “jurisdiction rests solely on diversity
    of citizenship and there is no controlling decision by the highest court of a state, a
    decision by an intermediate court should be followed by the Federal court, absent
    convincing evidence that the highest court would decide otherwise.” 
    Greystone, 661 F.3d at 1282
    (quotations omitted). We therefore consider decisions of New York
    intermediate appellate courts interpreting standard-form CGL policies and conclude they
    do not preclude coverage under the Policy here.17
    Aspen relies on decisions from New York’s intermediate appellate courts,
    contending they preclude coverage for the damages at issue here. But these cases (1) did
    not involve or failed to analyze the “subcontractor exception,” (2) involved CGL policies
    that predated the critical revisions ISO made in 1986, (3) relied on cases that have since
    been overturned, (4) involved faulty work by a contractor rather than a subcontractor, or
    (5) contained some combination of the above. These distinguishing factors provide
    ample “convincing evidence” that New York’s Court of Appeals would decline to find no
    17
    B&V suggests the Policy is different from the standard-form CGL policy, and
    thus New York cases interpreting the standard policy are inapplicable. See Aplt. Br. at 10
    (stating that the parties’ negotiation resulted in a “manuscript policy,” meaning that it
    “contains negotiated terms and is not a standard ISO form policy”); see also 
    id. at 27.
    But as Aspen points out, B&V never explains how the Policy’s language differs from the
    standard language. See Aplee. Br. at 32; see also Black & Veatch Corp. v. Aspen Ins.
    (UK) Ltd., No. 12-2350-SAC, 
    2016 WL 6804894
    , at *8 (D. Kan. Nov. 17, 2016) (“The
    parties do not argue that [the ‘occurrence’] definition is unusual or atypical for a CGL
    policy.”). We find that the Policy’s language is materially the same as the language
    found in ISO’s standard-form CGL policies. We nevertheless agree with B&V that New
    York case law does not foreclose coverage.

    Aspen relies heavily on Fuller for the proposition that CGL insurance policies are
    “not intended to insure against faulty workmanship or construction” and thus cannot
    cover the damages at issue here. See Aplee. Br. at 21. But Fuller is inapplicable here,
    and it relied on cases that involved CGL policies drafted before ISO’s 1986 changes.
    Fuller involved a coverage dispute over damages to a building that a developer
    had hired a contractor to 
    build. 613 N.Y.S.2d at 154
    . Due to a subcontractor’s faulty
    workmanship, the building suffered water damage. 
    Id. The contractor
    ’s CGL insurance
    carrier refused to pay the claim, and the contractor sued. 
    Id. The question
    was whether
    the contractor’s faulty workmanship constituted an “occurrence,” which was defined
    under the policy as “an accident, including continuous or repeated exposure to
    substantially the same general harmful conditions.” 
    Id. at 153.
    The court determined the
    damages were not an “occurrence” because they were not accidental but rather had been
    18
    The dissent refers to New York intermediate appellate court decisions carrying
    “precedential weight,” Dissent at 3, which they do in appropriate circumstances. But a
    court decision does not necessarily carry precedential weight when it is materially
    distinguishable from the case at hand. As we have shown, the New York cases that
    Aspen relies on, starting with Fuller, contain no discussion of CGL policies that contain a
    “subcontractor exception.” Moreover, as the New York Court of Appeals has said,
    Appellate Division decisions “are certainly not binding upon this court.” People v.
    Roche, 
    379 N.E.2d 208
    , 216 (N.Y. 1978). Nor are we required to follow such decisions
    when “other authority convinces us that the state supreme court would decide otherwise.”
    Daitom, Inc., v. Pennwalt Corp., 
    741 F.2d 1569
    , 1574 (10th Cir. 1984); see also Comm’r
    v. Estate of Bosch, 
    387 U.S. 456
    , 465 (1967).
    29
    caused by “intentional cost-saving” acts. 
    Id. at 155.
    Fuller is inapposite here for four
    reasons.
    First, Fuller does not address the issue here—whether damages caused by a
    subcontractor are covered by a CGL policy that expressly provides coverage for damages
    to an insured’s work arising from a subcontractor’s faulty workmanship. The policy in
    Fuller excluded damages to “that particular part of any property that must be restored,
    repaired or replaced” due to work that was performed incorrectly either by “you [the
    insured] or on your behalf [by a subcontractor].” 
    Id. at 153.
    The court thus concluded
    that the CGL policy in that case did not intend to cover damages to an insured’s own
    work, regardless of whether the contractor or its subcontractor caused the damages. The
    dissent reads Fuller to mean that any CGL policy employing the standard definition of
    “occurrence” necessarily excludes subcontractor-caused damages to an insured’s own
    work. See Dissent at 1. But this is overly broad. Fuller says only that the particular
    policy in that case “d[id] not insure against faulty workmanship in the work product
    itself.” 
    Fuller, 613 N.Y.S.2d at 155
    . The dissent takes this single passage out of context
    and concludes that New York intermediate appellate courts have held that the damages at
    issue here can never be an occurrence, see Dissent at 2, ignoring this critical distinction
    between the two cases.19
    19
    The dissent also reads too much into this opinion’s discussion of Fuller when it
    says “the majority concludes the Fuller rule only applies where the CGL policy does not
    include a Subcontractor Exception, even though no New York court has limited the rule
    in this way.” Dissent at 3. Our holding is not so prescriptive. We conclude only that
    Fuller does not preclude the damages at issue here from constituting a coverage-
    triggering “occurrence” under the Policy.
    30
    Second, Fuller relied on two cases from New York’s intermediate appellate courts
    to support its statement that CGL policies are not intended to cover damages to the
    insured’s own defective work product—Village of Newark v. Pepco Contractors,
    Inc., 
    472 N.Y.S.2d 66
    (N.Y. App. Div. 1984), aff’d, 
    465 N.E.2d 1261
    (N.Y. 1984),
    and Parkset Plumbing & Heating Corp. v. Reliance Ins. Co., 
    448 N.Y.S.2d 739
    (N.Y.
    App. Div. 1982). But both of these cases were decided before 1986, when the ISO
    clarified that standard-form CGL policies covered insureds for property damage to—or
    caused by—subcontractors’ work.
    Third, Fuller’s primary rationale for finding no “occurrence” is absent here.
    Fuller held that the damages at issue were not accidental but rather resulted from
    intentional cost-cutting measures and thus could not constitute an “occurrence.” Here,
    Aspen does not argue—nor does the record suggest—that the damage to the JBRs arose
    from any intentional or negligent acts by B&V or MTI.
    Fourth, Aspen cites Fuller to argue that B&V’s interpretation would transform the
    Policy into a surety for the performance of B&V’s work. Aplee. Br. at 21; see 
    Fuller, 613 N.Y.S.2d at 155
    (holding that the CGL policy was not “intended to insure [the
    general contractor’s] work product”). But allowing CGL policies to cover damage from
    subcontractor-caused construction defects would not convert insurance policies into
    surety performance bonds. See French at 139-40; see also 
    Greystone, 661 F.3d at 1288
    -
    89. Both insurance policies and performance bonds are used to spread risk, but they
    differ in fundamental ways. An insurance policy spreads the contractor’s risk. A
    performance bond guarantees completion of the contract upon the contractor’s default.
    31
    See French at 139-40 (“Performance bonds protect the property owner, while liability
    insurance protects the contractor.”). The “principal purpose[]” of insurance is to transfer
    financial responsibility from the policyholder to an insurer for damage caused by the
    policyholder’s negligence. 
    Id. at 140.
    Allowing CGL policies to cover construction
    defects caused by a subcontractor comports with the purpose of liability insurance—to
    protect the contractor, not the property owner.
    b. Other New York cases
    Aspen also cites Baker Residential Limited Partnership v. Travelers Insurance
    Co., 
    782 N.Y.S.2d 249
    , 250 (N.Y. App. Div. 2004), for the proposition that an
    “occurrence” happens under CGL policies only when damage to property is “distinct
    from the plaintiffs’ own work product.” See Aplee. Br. at 23. The Baker opinion, which
    consists of two paragraphs, cites only two cases. The first, Fuller, is inapt for the reasons
    explained above. The second, Pavarini Construction Co. v. Continental Insurance Co.,
    relies solely on Fuller. See 
    759 N.Y.S.2d 56
    , 57-58 (N.Y. App. Div. 2003). Neither of
    these opinions provides any discussion or guidance on interpreting policies with a
    “subcontractor exception.”
    Aspen next cites Ohio Casualty Insurance Co. v. Lewis & Clinch, Inc., No. 7:12-
    CV-1872, 
    2014 WL 6078572
    , at *9 (N.D.N.Y Nov. 13, 2014), for the same
    proposition—that damage to the insured’s own work is not a covered “occurrence” under
    CGL policies. Once again, however, Ohio Casualty relied entirely on the inapposite
    language in Fuller. See 
    id. Ohio Casualty
    is also an unpublished case from a federal
    32
    district court rather than a New York state court. Further, it did not involve a
    subcontractor’s faulty workmanship.
    Finally, Aspen provides a three-page string cite of cases from New York’s
    intermediate appellate courts and federal district courts, but these cases are unavailing for
    largely the same reasons addressed above. Every one of the 15 cases relied on Fuller.
    See, e.g., Eurotech Constr. Corp. v. QBE Ins. Corp., 
    26 N.Y.S.3d 703
    , 703 (N.Y. App.
    Div. 2016); Nat’l Union Fire Ins. Co. of Pittsburgh v. Turner Constr. Co., 
    986 N.Y.S.2d 74
    , 77 (N.Y. App. Div. 2014) (“National Union”); Maxum Indem. Co. v. A One Testing
    Labs., Inc., 
    150 F. Supp. 3d 278
    , 284 (S.D.N.Y. 2015). One of the cases, Exeter Building
    Corp. v. Scottsdale Insurance Co., 
    913 N.Y.S.2d 733
    , 735 (N.Y. App. Div. 2010), did not
    cite to Fuller directly but rather cited to Baker, which in turn relied on Fuller.
    Another of Aspen’s aforementioned cases, National Union, relied heavily on what
    used to be the seminal case regarding the issue of whether CGL policies cover
    construction defects—the New Jersey Supreme Court’s opinion in Weedo v. Stone-E-
    Brick, Inc, 
    405 A.2d 788
    (N.J. 1979). See National 
    Union, 986 N.Y.S.2d at 77
    ; see also
    French at 117. But Weedo has been overturned. Weedo held that CGL policies “do not
    cover an accident of faulty workmanship but rather faulty workmanship which causes an
    
    accident.” 405 A.2d at 796
    . The New Jersey Supreme Court “effectively overruled”
    Weedo in Cypress Point, holding that damages caused by the subcontractor’s faulty
    workmanship can constitute property damage under CGL policies. See French at 119
    33
    (“For numerous reasons, the Weedo decision is obsolete and of little value today in
    analyzing whether construction defects can constitute occurrences.”).20
    ***
    In sum, we conclude that New York intermediate appellate court decisions would
    not persuade the New York Court of Appeals to find that the damages at issue here were
    not an “occurrence”—particularly in the face of the other reasons discussed above. The
    dissent submits that if there is “any debate regarding the clarity of New York Law, we
    should certify the question.” Dissent at 5 n.6. In Lehman, the Supreme Court said that
    when a federal court faces a novel state law question in an area where state law is highly
    unsettled, it may be appropriate to certify the question to the state’s highest court. 416
    20
    In Revisiting Construction Defects, French further explains why Weedo is
    obsolete:
    One, the [Weedo] court did not analyze the definition of
    “occurrence” in the policy at issue and did not even address whether the
    faulty stucco work constituted an occurrence.
    Two, the court did not analyze the definition of “property damage”
    in the policy at issue and did not address whether the faulty stucco work
    was property damage or caused property damage.
    Three, [a 1971 law review article] on which the court relied, did not
    analyze or address the issues of whether construction defects constitute
    occurrences or property damage. Instead, [the] article focused on the
    business risk exclusions contained in the 1966 CGL policy form, and []
    then offered . . . unsupported conclusions regarding the intent of the
    exclusions.
    Four, . . . the business risk exclusions at issue in the case were
    redrafted in 1986 to provide much narrower reductions in coverage than the
    earlier versions of such exclusions.
    French at 119 (paragraph breaks added) (citations 
    omitted). 34 U.S. at 390-91
    (“We do not suggest that where there is doubt as to local law and where
    the certification procedure is available, resort to it is obligatory.”) As noted in Lehman,
    whether to certify a question “rests in the sound discretion of the federal court.” 
    Id. at 391.
    We have declined to do so here.
    5. Second Circuit Case Law is Distinguishable
    Aspen also relies on a Second Circuit decision, J.Z.G. Resources, Inc. v. King, 
    987 F.2d 98
    (2d Cir. 1993), which applied New York law to a construction dispute. See
    Aplee. Br. at 22. In J.Z.G., a real estate developer sued a contractor for building roads at
    the wrong elevation and 
    location. 987 F.2d at 100
    . The contractor sought coverage for
    damage to the roads themselves. 
    Id. The Second
    Circuit held the contractor’s CGL
    policy did not encompass the road damage, explaining that “this circuit has held that a
    CGL policy did not provide coverage for a claim against an insured for the repair of
    faulty workmanship that damaged only the resulting work product.” 
    Id. at 102-03.
    J.Z.G. is not persuasive here. First, it did not involve faulty subcontractor work.
    Second, it relied on cases and commentary either predating or failing to take into account
    ISO’s 1986 changes.21 In particular, it relied on the following passage from a 1971 law
    review article: “The risk intended to be insured is the possibility that the goods, products
    or work of the insured, once relinquished or completed, will cause bodily injury or
    damage to property other than to the product or completed work itself, and for which the
    21
    As explained above, in 1986, ISO revised the standard CGL insurance policy to
    clarify—in ISO’s words—that the policy “cover[ed] . . . damage to, or caused by, a
    subcontractor’s work after the insured’s operations are completed.” ISO 1986 Circular.
    35
    insured may be found liable.” 
    Id. (quoting Roger
    C. Henderson, Insurance Protection for
    Products Liability and Completed Operations-What Every Lawyer Should Know, 
    50 Neb. L
    . Rev. 415, 441 (1971)).
    But this article analyzed the business risk exclusion contained in the ISO’s 1966
    standard-form CGL policy, which precluded coverage for damage to construction
    projects caused by subcontractors. See French at 107, 118. By 1986, the ISO had
    acceded to contractors’ demands to provide coverage for faulty subcontractor work and
    replaced that exclusion with the current language. Commentators have noted that this
    article is outdated and “of little value today in understanding . . . whether construction
    defects can constitute occurrences.” 
    Id. at 119.
    “Following [ISO’s] 1986 changes . . . ,
    one would expect that . . . [the] 1971 law review article would be cited by courts only as a
    historical note regarding the evolution of the policy language and law in this arena.” 
    Id. “Surprisingly, however,
    . . . [the] article continue[s] to be relied upon by some courts
    from time to time, particularly in decisions where the court misinterprets the issue before
    it.” 
    Id. The analysis
    underlying J.Z.G. is therefore outdated and of no use here.
    III. CONCLUSION
    Under the Policy, the damages at issue here were caused by a coverage-triggering
    “occurrence.” First, the damages were accidental and resulted in harm to a third-party’s
    property, thus meeting the Policy’s definition of an “occurrence.” Second, the district
    court’s interpretation would violate New York’s rule against surplusage by rendering the
    “subcontractor exception” meaningless. Third, the changes ISO has made to standard-
    form CGL policies demonstrate that the policies can cover the damages at issue here.
    36
    Fourth, the overwhelming trend among state supreme courts has been to recognize such
    damages as “occurrences.” Fifth, New York intermediate appellate decisions are
    distinguishable, outdated, or otherwise inapplicable. We predict the New York Court of
    Appeals would decline to follow these decisions and instead would join the clear trend
    among state supreme courts holding that damage from faulty subcontractor work
    constitutes an “occurrence” under the Policy. For the foregoing reasons, we vacate the
    district court’s summary judgment decision and remand for reconsideration in light of
    this opinion. 22
    22
    We grant Appellees’ August 4, 2017 motion for leave to file additional authority.

    BRISCOE, Circuit Judge, dissenting.
    I
    I respectfully dissent because I believe New York law forecloses insurance
    coverage for damage to the work product of an insured, which is precisely the type of
    damage at issue here. Therefore, because I agree with the district court’s conclusion that
    “New York law’s governing definition of ‘occurrence’ does not recognize liability
    coverage” in this instance, D. Ct. Order at 56, I would affirm the district court.
    The rule among intermediate appellate courts in New York has been that a CGL
    policy that includes a standard definition of “occurrence”:
    does not insure against faulty workmanship in the work
    product itself but rather faulty workmanship in the work
    product which creates a legal liability by causing bodily
    injury or property damage to something other than the work
    product.
    George A. Fuller Co. v. U.S. Fid. & Guar. Co., 
    613 N.Y.S.2d 152
    , 155 (N.Y. App. Div.
    1st Dep’t. 1994).1
    In recent years, New York courts have applied this rule to hold that the insured can
    only recover when the “damage caused by faulty workmanship [is] to something other
    than [to] the work product.” I.J. White Corp. v. Columbia Cas. Co., 
    964 N.Y.S.2d 21
    , 23
    (N.Y. App. Div. 1st Dep’t. 2013) (coverage applied because the damage was to cakes, not
    the freezer that the insured built). Further, intermediate state appellate decisions have
    1
    See also Eurotech Constr. Corp. v. QBE Ins. Corp., 
    26 N.Y.S.3d 703
    (N.Y. App.
    Div. 1st Dep’t. 2016); Bonded Concrete, Inc. v. Transcon. Ins. Co., 
    784 N.Y.S.2d 212
    ,
    213 (N.Y. App. Div. 3d Dep’t. 2004); Baker Residential Ltd. P’ship v. Travelers Ins. Co.,
    
    782 N.Y.S.2d 249
    , 250 (N.Y. App. Div. 3d Dep’t. 2004).
    held that even when a subcontractor caused the damage, an insured general contractor
    cannot be covered for damage to its own work product because it is “responsible for the
    entire project[,] and all work done by [any] subcontractor was done on” behalf of the
    general contractor. Pavarini Constr. Co. v. Cont’l Ins. Co., 
    759 N.Y.S.2d 56
    , 57 (N.Y.
    App. Div. 1st Dep’t. 2003); see also Nat’l Union Fire Ins. Co. of Pittsburgh, Pa. v. Turner
    Constr. Co., 
    986 N.Y.S.2d 74
    , 77 (N.Y. App. Div. 1st Dep’t. 2014).
    New York intermediate appellate courts have therefore developed a rule that a
    CGL policy using the standard definition of “occurrence” cannot cover damage to the
    insured’s own work product, even when errors by the insured or its subcontractors cause
    the damage. Applying that rule to this case, there was no “occurrence”—which would
    trigger coverage—because the damage was to the jet bubbling reactors, which were
    B&V’s own work. Because B&V has not satisfied its “initial burden of proving that the
    damage was the result of an ‘accident’ or ‘occurrence,’” we need not proceed to examine
    whether an exclusion and an exception to that exclusion apply. Consol. Edison Co. of
    N.Y. v. Allstate Ins. Co., 
    774 N.E.2d 687
    , 692 (N.Y. 2002).
    Given this analysis, I would affirm the district court.
    II
    The majority, however, reverses the district court. In doing so, the majority
    concludes there is an insured “occurrence” in this case, in part because it does not apply
    the New York cases. It instead determines that the rule applied in Fuller, Pavarini, I.J.
    White and other New York appellate cases is “outdated” and inapplicable to this case
    because the rule’s logic preceded the Insurance Services Office, Inc.’s 1986 revisions to
    2
    the standard CGL policies, Op. at 37, making the cases “materially distinguishable.” 
    Id. at 29
    n.19. In other words, the majority concludes the Fuller rule only applies where the
    CGL policy does not include a Subcontractor Exception, even though no New York court
    has limited the rule in this way. See D. Ct. Order at 31 (concluding there is no indication
    in New York law that a Subcontractor Exception would alter New York law, and noting
    that an unpublished federal district court case involving a Subcontractor Exception “does
    not reflect any argument or discussion of this exception as having the effect of modifying
    New York’s law”) (citing Ohio Cas. Ins. Co. v. Lewis & Clinch, Inc., No. 7:12-CV-1872
    (GTS/TWD), 
    2014 WL 6078572
    (N.D.N.Y. Nov. 13, 2014)).2
    I conclude, however, that in declining to apply the rule that New York’s
    intermediate appellate courts have applied we exceed our proper role as a court of review
    in a diversity action. Our role is to determine how the New York Court of Appeals would
    decide this case. To accomplish this task, we must apply relevant New York case law. If
    the New York courts have held that damage to the insured’s own work product is not an
    “occurrence,” even if the damage results from a subcontractor’s error, it is not our role to
    tell the New York courts that their rulings do not carry any precedential weight or are
    limited to their facts.

    Instead, in the circumstances presented here, where “there is no controlling
    decision by the highest court of a state, a decision by an intermediate court should be
    followed by the Federal court, absent convincing evidence that the highest court would
    decide otherwise.” United Fire & Cas. Co. v. Boulder Plaza Residential, LLC, 
    633 F.3d 951
    , 957 (10th Cir. 2011) (quotation omitted). The majority, however, believes we do
    have convincing evidence that the New York Court of Appeals would not apply the
    Fuller rule to a CGL policy with a Subcontractor Exception. The majority reviews
    extrinsic evidence about how CGL policies are generally drafted, scholarly sources, and
    persuasive authority from courts applying the law of other jurisdictions. Armed with
    these authorities, the majority “predict[s] the New York Court of Appeals would decline
    to follow [the Fuller rule] and instead would join the clear trend among state supreme
    courts holding that damage from faulty subcontractor work constitutes an ‘occurrence.’”
    Op. at 37.
    This is a bridge too far. In reaching its conclusion, the majority takes the sort of
    step the Supreme Court has criticized by “turn[ing] to the law of other jurisdictions” to
    determine what the New York Court of Appeals “would probably” decide in this case.
    Lehman Bros. v. Schein, 
    416 U.S. 386
    , 389 (1974). This might be acceptable if existing
    New York law were “difficult or uncertain.” Colony Ins. Co. v. Burke, 
    698 F.3d 1222
    ,
    1235 (10th Cir. 2012) (quotation omitted). But that is not the case here. It is not difficult
    to ascertain how New York courts would decide the issues presented here—nor does the
    majority say it would be difficult. The majority merely attempts to distinguish New York
    case law, and then describes New York law as if “this case apparently raises an issue of
    4
    first impression.” Walker v. BuildDirect.com Techs., Inc., 
    733 F.3d 1001
    , 1005 (10th
    Cir. 2013).3
    Even assuming, arguendo, that we could legitimately distinguish Fuller and its
    progeny, meaning there are “no controlling precedents,” Elkins v. Moreno, 
    435 U.S. 647
    ,
    662 (1978),4 and “a state court has not yet had the opportunity to interpret the pertinent”
    question, Kansas Judicial Review v. Stout, 
    519 F.3d 1107
    , 1119 (10th Cir. 2008)
    (quotation omitted),5 I do not believe we should exercise our discretion to decide how the
    New York Court of Appeals would rule.6 Rather, if there are truly no New York cases to
    guide us, certifying the question to the New York Court of Appeals acknowledges that
    “[w]hen federal judges [outside New York] attempt to predict uncertain [New York] law,
    they act . . . as ‘outsiders’ lacking the common exposure to local law which comes from
    sitting in the jurisdiction.” Lehman 
    Bros., 416 U.S. at 391
    . In other words, I do not
    believe federal courts should predict what a state court will likely do, without any state

    The majority is correct that, as an initial matter, we are tasked with discerning
    what the New York Court of Appeals would decide if this case came before it. Op. at 9
    n.7 (citing Bird v. W. Valley City, 
    832 F.3d 1188
    , 1199 (10th Cir. 2016)). Yet, if—
    hypothetically—a review of New York cases does not indicate what the New York Court
    of Appeals would likely decide, it is not our place to guess about the result. Though the
    majority portrays this dissent as treating the two forms of analysis interchangeably, see
    
    id., I emphasize
    that I believe we can discern how the New York Court of Appeals would
    rule based on existing New York case law. But if there is any debate regarding the clarity
    of New York law, we should certify the question.

    guidance, because “a State can make just the opposite [determination of what the federal
    court predicts] her law” to be.

    Therefore, even if New York law were distinguishable—which, as stated above, I
    do not believe it is—I would not reverse the district court, but would certify the question
    to the New York Court of Appeals.
