    IN THE SUPREME COURT OF THE STATE OF HAWAI#I
    NAUTILUS INSURANCE COMPANY,
    Plaintiff-Appellant,
    vs.
    LEXINGTON INSURANCE COMPANY, DOE DEFENDANTS 1-10,
    Defendants-Appellees.
    SCCQ-12-0000977
    ORIGINAL PROCEEDING
    February 13, 2014
    RECKTENWALD, C.J., NAKAYAMA, ACOBA, McKENNA, AND POLLACK, JJ.
    OPINION OF THE COURT BY ACOBA, J.
    The United States Court of Appeals for the Ninth
    Circuit (Ninth Circuit) certified the following questions of law
    to this court:
    1.    Whether an insurer may look to another insurer’s
    policy in order to disclaim the duty to defend, where the
    complaint in the underlying lawsuit alleges facts within
    coverage.
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    2.    Whether an “other insurance” clause that purports to
    release an otherwise primary insurer of the duty to defend
    if the insurer becomes excess as to liability is
    enforceable.
    3.    Whether the irreconcilability of “other insurance”
    provisions in otherwise primary insurance policies should be
    determined before or after the operation of the “other
    insurance” provisions is determined.
    4.    Whether, and when, an excess insurer, or an otherwise
    primary insurer who becomes an excess insurer by operation
    of an “other insurance” clause, has a duty to defend.
    I.
    A.
    VP & PK (ML) LLC (VP & PK) is the owner and developer
    of a tract of land in the Maui Lani Project District.               VP & PK
    purchased a Commercial General Liability insurance policy1 for
    its work on the Maui Lani site from Defendant-Appellee Lexington
    Insurance Company (Lexington).        The policy’s Occurrence Form
    included the following “Other Insurance” provision:
    4.    Other Insurance
    If other valid and collectible insurance is available
    to the insured for a loss we cover under Coverages A
    or B of this Policy, our obligations are limited as
    follows:
    a.    Primary Insurance
    This insurance is primary except when b. Excess Insurance,
    below, applies. If this insurance is primary, our
    obligations are not affected unless any of the other
    insurance is also primary. Then, we will share with all
    that other insurance by the method described in c. Method of
    Sharing, below.
    1
    “Liability insurance” is defined as “[a]n agreement to cover a
    loss resulting from the insured’s liability to a third party, such as a loss
    incurred by a driver who injures a pedestrian.” Black’s Law Dictionary 873
    (9th ed. 2009). “The insured’s claim under the policy arises once the
    insured’s liability to a third party has been asserted.” 
    Id. 2 ***FOR
    PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    b.    Excess Insurance
    This insurance is excess over:
    . . . .
    (2)    Any other primary insurance
    available to you covering
    liability for damages arising
    out of the premises or
    operations of the “products-
    completed operations” hazard
    for which you have been added
    as an additional insured by
    attachment of an endorsement.
    When this insurance is excess, we will have no
    duty under Coverages A or B to defend the
    insured against any “suit” if any other insurer
    has a duty to defend the insured against that
    “suit”. If no other insurer defends, we will
    undertake to do so, but we will be entitled to
    the insured’s rights against all those other
    insurers.
    . . . .
    c.    Method of sharing
    If all of the other insurance permits contribution by
    equal shares, we will follow this method also. Under
    this approach each insurer contributes an equal amount
    until it has paid its applicable limit of insurance or
    none of the loss remains, whichever comes first.
    If any of the other insurance does not permit
    contribution by equal shares, we will contribute by
    limits. Under this method, each insurer’s share is
    based on the ratio of its applicable limit of
    insurance to the total applicable limits of insurance
    of all insurers.
    (Emphases added.)     Lexington did not include Kila Kila
    Construction (Kila Kila) as an additional insured.
    Kila Kila was one of VP & PK’s subcontractors for the
    Maui Lani development.      Kila Kila purchased a Commercial General
    Liability Coverage insurance policy for its work on the Maui Lani
    site from Plaintiff-Appellant Nautilus Insurance Company
    3
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    (Nautilus).     The Commercial General Liability Coverage form
    contained an “Other Insurance” provision, which stated as
    follows:
    4.     Other Insurance
    If other valid and collectible insurance is available
    to the insured for a loss we cover under Coverages A
    or B of this Coverage Part, our obligations are
    limited as follows:
    a.    Primary Insurance
    This insurance is primary except when b. below
    applies. If this insurance is primary, our
    obligations are not affected unless any of the
    other insurance is also primary. Then, we will
    share with all that other insurance by the
    method described in c. below.
    b.    Excess Insurance
    This insurance is excess over:
    . . . .
    (2)   Any other primary insurance
    available to you covering liability
    arising out of the premises or
    operations for which you have been
    added as an additional insured by
    attachment of an endorsement.
    (Emphases added.)      Nautilus’s policy also contained an
    “Additional Insured Endorsement” modifying the Commercial General
    Liability Coverage and adding VP & PK as an additional insured:
    SECTION II - WHO IS AN INSURED is amended to include as an
    insured the person or organization shown in the Schedule
    below, but only for liability arising out of your negligence
    and only for occurrences or coverage not otherwise excluded
    in the policy to which this endorsement applies.

    Both parties’ General Commercial Liability policies
    include duties to both defend and indemnify.
    B.
    On June 3, 2008, Karen Goo and a number of Maui
    residents sued VP & PK, Kila Kila, and other VP & PK
    subcontractors for damages resulting from construction in Maui
    Lani.   The complaint alleged facts falling within the coverage of
    both policies.    Nautilus funded the defense of both Kila Kila and
    VP & PK during the entirety of the Goo lawsuit.            Ultimately, VP &
    PK was found solely liable on some claims and ordered to pay
    damages totaling $232,700.      Kila Kila was not found liable on any
    claims.
    C.
    Lexington acknowledged that it would indemnify VP & PK
    for the jury verdict, and satisfied the entirety of the judgment
    against VP & PK.    It does not appear to dispute its obligation to
    pay the full amount of damages.       However, Lexington denies any
    obligation to contribute to Nautilus’s costs in funding the
    defense.
    D.
    On September 14, 2009, Nautilus filed a Complaint in
    the Hawai#i Circuit Court of the Second Circuit, seeking, inter
    5
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    alia, a declaration that Lexington owed VP & PK a duty to defend
    and that it breached that duty, and (2) equitable contribution
    from Lexington for defense costs.         On November 10, 2009,
    Lexington removed the case to the District Court,2 pursuant to 28
    U.S.C. 1332(a)(1).3     On November 17, 2010, the District Court
    granted summary judgment to Lexington on all of Nautilus’s
    claims.
    The District Court found that (1) Lexington was
    permitted to look beyond the face of the complaint and its policy
    -- and, specifically, to Nautilus’s policy -- to determine
    whether it had a duty to defend; (2) Lexington’s policy was in
    excess to Nautilus’s policy; (3) as a result, Lexington’s duty to
    defend had never been triggered; and (4) Nautilus was entitled to
    neither a declaratory judgment nor any contribution for the
    defense costs.     Nautilus Ins. Co. v. Lexington Ins. Co., Cv. No.
    90-00537 DAE-LEK, 
    2010 WL 4812742
    , at *12-16 (D. Haw. Nov. 17,
    2010).
    Nautilus appealed to the Ninth Circuit on December 14,
    2010, and on October 9, 2012, the Ninth Circuit sua sponte
    requested that the parties file supplemental briefing addressing

    28 U.S.C. 1332(a)(1) provides that “[t]he district courts shall

    costs, and is between (1) citizens of different States[.]”

    whether questions in the case should be certified to this court,
    and inviting them to comment on four proposed questions for
    certification.    Neither party objected to certification in their
    briefs, and both concede that Hawai#i law governs this
    controversy.
    On November 2, 2012, the Ninth Circuit filed a request
    with this court to answer four certified questions.           Hawai#i
    Rules of Appellate Procedure Rule 13(a) provides that “[w]hen a
    federal district or appellate court certifies to the Hawai#i
    Supreme Court that there is involved in any proceeding before it
    a question concerning the law of Hawai#i that is determinative of
    the cause and that there is no clear controlling precedent in the
    Hawai#i judicial decisions, the Hawai#i Supreme Court may answer
    the certified question by written opinion.”          On January 10, 2013,
    this court accepted the certified questions.          Nautilus filed its
    Opening Brief on August 5, 2013, Lexington filed its Answering
    Brief on September 12, 2013, and Nautilus filed a Reply Brief on
    September 26, 2013.
    II.
    Question 1:   Whether an insurer may look to another
    insurer’s policy in order to disclaim the duty to defend, where
    the complaint in the underlying lawsuit alleges facts within
    coverage.
    7
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    A.
    1.
    Both parties’ arguments on this question focus on this
    court’s 2000 opinion in Dairy Road Partners v. Island Ins. Co.,
    92 Hawai#i 398, 
    992 P.2d 93
    (2000).          However, we hold that Dairy
    Road Partners does not clearly resolve the scenario presented by
    this certified question.
    In Dairy Road Partners, the insurer, Island Insurance,
    disclaimed its duty to defend insureds Dairy Road Partners (DRP)
    and Shell in a pending action.          92 Hawai#i at 
    408, 992 P.2d at 103
    .    The complaints against the insureds alleged facts that
    would fall within Island Insurance’s coverage, thereby requiring
    that Island Insurance defend the claims.4            
    Id. at 414,
    992 P.2d
    at 109.     However, Island Insurance conducted its own
    investigation and disclaimed the defense based on the facts
    uncovered in that investigation, which would apparently put the
    underlying events outside the scope of Island Insurance’s
    coverage.      
    Id. at 409,
    992 P.2d at 104.
    In reaching its conclusion as to whether Island
    Insurance had a duty to defend under these circumstances, this
    court relied on Hawai#i insurance law principles with respect to
    the duty to defend.        
    Id. at 411-13,
    992 P.2d at 106-08.         The
    4
    The opinion noted that “Island [Insurance] does not dispute that
    the complaints in both of the underlying lawsuits allege claims that, if
    proven, would be covered by the policy.” 
    Id. at 414,
    992 P.2d at 109.
    8
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    operative question was whether, “for the purposes of overcoming
    the duty to defend, Island [Insurance] was permitted to conduct a
    factual investigation despite the allegations of the underlying
    complaints.”   
    Id. at 415,
    992 P.2d at 110 (emphases in original).
    Prior case law in Hawai#i had indicated that “insurers
    may generally overcome their duty to defend by relying on
    ‘factual’ sources beyond the pleadings[,]” and Dairy Road
    Partners expressed concern about this holding, because of the
    potential for adverse consequences to insureds.           
    Id. at 417,
    992
    P.2d at 112.   First, the insured could “be saddled with the
    Procrustean dilemma of being forced to adduce facts proving his
    or her own liability in the underlying lawsuit in order to
    satisfy the insurer that there may be merit to the underlying
    covered claim.”    
    Id. For example,
    in Dairy Road Partners, DRP
    would have had to prove that its employee was acting within the
    scope of his employment in order to demonstrate to Island
    Insurance that DRP had coverage under its policy and thus Island
    Insurance was required to defend.        
    Id. However, DRP
    would be
    liable in the underlying litigation if its employee was found to
    be acting within the scope of his employment.          
    Id. Thus, DRP
    would be compelled to take inconsistent positions.           
    Id. Second, this
    court was also concerned with the
    inconsistent judgments that could result if an insurer could look
    to facts outside the complaint in disclaiming its duty to defend.
    9
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    
    Id. Dairy Road
    Partners explained that “[a] circuit court
    presiding over a declaratory judgment action might rule, based on
    an insurer’s superior production of evidence concerning material
    facts that will be directly in dispute in the underlying lawsuit,
    that there is no possibility of coverage[,]” and “[s]ubsequently,
    the trier of fact in the underlying lawsuit . . . might find that
    the insured is liable on a claim covered by the policy.”              
    Id. (emphasis in
    original).
    This court noted that “the majority of jurisdictions
    addressing the issue forbade insurers from relying upon extrinsic
    evidence for the purposes of disclaiming the duty to defend.”
    
    Id. at 418,
    992 P.2d at 113.         Dairy Road Partners ultimately
    adopted the majority rule, with a limited exception, wherein an
    insurer “may only disclaim its duty to defend by showing that
    none of the facts upon which it relies might be resolved
    differently in the underlying lawsuit.”           
    Id. at 422,
    992 P.2d at
    117 (emphasis in original).        In other words, the decision held an
    insurer who relied on extrinsic facts in disclaiming its duty to
    defend would have to show that those facts could not be disputed
    in the underlying lawsuit.        
    Id. Otherwise, the
    insurer would not
    be allowed to disclaim its duty to defend based on those
    extrinsic facts.      
    Id. To illustrate,
    where an insurer argues
    that an occurrence was outside of the effective period of the
    policy, an insurer would likely be able to rely on that extrinsic
    10
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    fact, because “the parameters of the effective period of the
    policy would not normally be subject to dispute in the underlying
    action.”   
    Id. at 422
    n.14, 992 P.2d at 117 
    n.14.
    Holding thus, Dairy Road Partners concluded that Island
    Insurance was required to defend DRP and Shell, because the
    additional facts it uncovered through its own investigation were
    “inextricably intertwined in the factual matters at issue in the
    underlying lawsuits and [could not], therefore, serve as a basis
    for disclaiming the duty to defend.”        
    Id. at 423,
    992 P.2d at 118
    (emphasis added).
    2.
    Nautilus interprets the Dairy Road Partners decision as
    dispositive on the issue of whether an insurer may look to “other
    insurance” to disclaim its duty to defend.         Under Dairy Road
    Partners, Nautilus asserts, “an insurer that issues a general
    liability policy to an insured is obligated to defend a claim
    whenever there is a ‘mere potential for coverage’ under the
    policy.”   (Emphasis in original.) (Quoting 
    id. at 413,
    992 P.2d
    at 108.)   According to Nautilus, Dairy Road Partners completely
    excluded the possibility for an insurer to look to any extrinsic
    evidence beyond the allegations in the complaint in determining
    whether it had the duty to defend, unless such evidence would not
    bear any relation to the question of liability in the underlying
    suit.
    11
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Nautilus avers that the provision in its policy, adding
    VP & PK as additional insureds, would constitute extrinsic
    evidence bearing a relation to the question of liability in the
    underlying suit, and thus cannot be considered by Lexington in
    disclaiming its duty to defend.       In Nautilus’s view, the “facts”
    this court referred to in Dairy Road Partners “(1) must be
    relevant to the underlying lawsuit, and (2) cannot be open to a
    different resolution than what the insurer believes them to be.”
    Lexington, on the other hand, responds that “[t]o find
    that insurers may not consider other policies covering their
    insured would deprive them of essential information in
    ascertaining whether there is a duty to defend.”           Lexington
    argues that to hold otherwise “would render ‘other insurance’
    clauses meaningless, in contravention of this court’s case law
    holding that contract provisions should not be interpreted such
    that they are rendered meaningless.        (Citing Stanford Carr Dev.
    Corp. v. Unity House, Inc., 111 Hawai#i 286, 297, 
    141 P.3d 459
    ,
    470 (2006).) (Other citations omitted.)
    As to the import of Dairy Road Partners, Lexington
    avers that that decision does not preclude an insurer from
    looking at the available insurance policies in order to determine
    whether or not it has a duty to defend an insured.           According to
    Lexington, this court “focused on the unintended consequences of
    12
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    permitting insurers to rely on factual sources beyond the
    pleadings.”   (Emphasis added.)
    Lexington emphasizes that the two concerns articulated
    by this court in Dairy Road Partners, first, that an insured
    would have to prove his or her own liability in the underlying
    lawsuit in order to satisfy the insurer that it has the duty to
    defend, and second, that allowing insurers to rely on factual
    sources behind the pleadings that may result in inconsistent
    judgments, are not present in this case.         Instead, it argues, “VP
    & PK was not forced to allege facts proving its own liability in
    order to trigger the duty to defend because Nautilus had already
    agreed to provide a defense; and [] there was no risk of
    inconsistent judgments because the Nautilus and Lexington
    policies were not before the jury in the [u]nderlying [a]ction.”
    3.
    Dairy Road Partners clearly established the principles
    that the duty to defend is broader than the duty to indemnify,
    and that “[a]ll doubts as to whether a duty to defend exists are
    resolved against the insurer and in favor of the insured[.]”               92
    Hawai#i at 
    412, 992 P.2d at 107
    (citations and internal quotation
    marks omitted).    In the same vein, this court has held that “the
    duty to defend ‘rests primarily on the possibility that coverage
    exists.   This possibility may be remote but if it exists, the
    insurer owes the insured a defense.’”        
    Id. (emphasis in
    original)
    13
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    (quoting Standard Oil Co. of California v. Hawaiian Ins. & Guar.
    Co., Ltd., 
    65 Haw. 521
    , 527, 
    654 P.2d 403
    , 407 (1973)) (other
    citation and internal quotation marks omitted).           These precepts
    are ultimately relevant to our answers to the certified questions
    presented to this court.
    However, the specific holding in Dairy Road Partners
    does not appear dispositive of the outcome of the first certified
    question.    The extrinsic evidence considered in Dairy Road
    Partners included factual matters relevant to the outcome of the
    underlying litigation.     Here, in contrast, the question is
    whether an insurer may take into account the operation of its
    policy in conjunction with other insurance policies, to determine
    if it must defend a particular suit.        Thus, the insurer would be
    looking at the construction and operation of other insurance
    policies in disclaiming a duty to defend, which presents some
    different considerations than the “extrinsic evidence” that was
    at issue in Dairy Road Partners.
    The clearest signal that Dairy Road Partners does not
    control in this case is the rationale expressed in Dairy Road
    Partners that allowing insurers to rely on extrinsic factual
    evidence could potentially (1) compel the insured to adduce facts
    proving his or her own liability in the underlying suit; and (2)
    result in inconsistent judgments regarding facts that would be in
    dispute in the underlying lawsuit as well as relevant to the
    14
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    insurer’s duty to defend.       92 Hawai#i at 
    417, 992 P.2d at 112
    .
    As Lexington correctly points out, these concerns will generally
    not be implicated when the question is whether an insurer should
    be able to look to other insurance companies’ policies when
    disclaiming the duty to defend.        The question of whether the
    insured has coverage under another policy is typically one of
    contract interpretation, and thus may not involve issues that
    could be in dispute in the underlying action.5
    While the insurance company in Dairy Road Partners
    conducted independent investigative research into the
    circumstances of the underlying occurrence, here, in contrast,
    the “research” contemplated would be identifying and interpreting
    the policies of other companies that had potentially applicable
    insurance.    Therefore, extrinsic “facts” may be distinguished
    analytically from extrinsic “policies”, and Dairy Road Partners
    does not mandate a specific answer to the first certified
    question.
    B.
    “Primary insurance is typically the first layer of
    coverage.”    See 23 Appleman, Insurance Law and Practice § 145.1,
    5
    As this case illustrates, however, sometimes the question of
    whether the insured is covered under another policy will involve facts that
    could be relevant to the underlying litigation. As will be explained infra,
    the question of whether VP & PK is covered under Nautilus’s policy turns on
    whether Kila Kila was negligent -- an issue squarely addressed in the
    underlying litigation.
    15
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    at 3 (2003) [hereinafter “Appleman”]; Liberty Mut. Ins. Co. v.
    Sentinel Ins. Co., 120 Hawai#i 329, 354, 
    205 P.3d 594
    , 619 (App.
    2009).    A carrier’s obligations under a primary policy attach
    whenever there is a possibility of coverage, even when that
    possibility is remote.       See, e.g., Dairy Road Partners, 92
    Hawai#i at 
    412, 992 P.2d at 107
    .         “The second layer of coverage
    is excess coverage.”       23 Appleman § 145.1, at 4.        The difference
    between coverages has been explained thusly:
    Because separate premiums are assessed against the insured
    for excess and primary coverage, excess coverage is not
    triggered until the underlying primary policy limits are
    exhausted within the meaning of the excess policy. Also, in
    contrast to primary policies, a pure excess policy provides
    specific coverage above an underlying limit of primary
    insurance and often will refer directly within the excess
    policy declaration and policy itself to primary insurers as
    well as other excess insurers.
    
    Id. 1. Here,
    Lexington’s policy provides that its otherwise
    primary insurance becomes excess in the event that “other
    insurance” is available.        This is known as an “other insurance”
    clause.    See Walton v. State Farm Mut. Auto Ins. Co., 
    55 Haw. 326
    , 329, 
    518 P.2d 1399
    , 1401 (1974).          Such clauses have been
    upheld in this jurisdiction, so long as “‘they are not in
    contravention of statutory inhibitions or public policy.’”

    to this case, Lexington’s otherwise primary policy becomes an
    excess policy by operation of the “other insurance” clause.
    The relationship between the potential primary and
    excess coverages in this case is different from many other types
    of cases where excess coverage is considered.           Here, Lexington’s
    policy was primary coverage for VP & PK (not taking into
    consideration the “other insurance clause”), and Nautilus’s
    policy was primary coverage for Kila Kila, and possibly also
    provided primary coverage for VP & PK by operation of Nautilus’s
    “Additional Insureds” endorsement.         Thus, presumably, VP & PK
    negotiated with Lexington and paid premiums for a primary
    coverage policy that included, inter alia, the “other insurance”
    clause, and Kila Kila negotiated with Nautilus and paid premiums
    for a primary coverage policy that included, inter alia, the
    additional insured endorsement of VP & PK.6
    2.
    To reiterate, the policy that Nautilus issued to Kila
    Kila included an endorsement of VP & PK as an “additional
    insured”, stating that “WHO IS INSURED is amended to include as
    an insured [VP & PK], but only for liability arising out of [Kila
    Kila’s] negligence and only for occurrences or coverage not
    6
    Nautilus’s policy also contained a substantially similar “other
    insurance” provision, but as will be explained infra, since there are no
    allegations that Kila Kila had “other insurance”, this provision from
    Nautilus’s policy is not at issue.
    17
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    otherwise excluded in the policy to which this endorsement
    applies.” (Emphasis added.)      Lexington’s “other insurance”
    clause, in turn, only applies if VP & PK has other insurance, and
    so in order for Lexington’s “other insurance” clause to become
    operable, it appears that the “additional insured” endorsement in
    Nautilus’s policy must also be triggered.
    Nautilus alleges that the “additional insured”
    endorsement in its policy could have been resolved in two
    different ways, depending on the outcome in the underlying case.
    Based on the language of the endorsement, Nautilus asserts that
    VP & PK would only be covered as an additional insured under its
    policy in the event that Kila Kila were found to be negligent.
    According to Nautilus, the coverage of VP & PK was contingent on
    the outcome of the underlying litigation, and therefore,
    Lexington had no right to consider Nautilus’s policy when
    disclaiming the duty to defend.
    Nautilus further cites to a New York case, 83 Kajima
    Const. Servs., Inc. v. Cati, Inc., 
    302 A.D.2d 228
    (N.Y. App. Div.
    2003), in support of its contention.        Nautilus analogized the
    circumstances in Cati, Inc., which involved two insurers with
    “additional insured” language in one of the policies, to those in
    this case.   According to Nautilus, the coverage of one of the
    insureds in Cati, Inc. was contingent on “the negligence or
    responsibility of the named insured.”        (Quoting Cati, Inc., 302
    18
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    A.D. at 228.)   The New York Appellate Division, First Department,
    held that under those circumstances, the duty of one of the
    insurers to defend could be “deferred pending determination of
    the underlying action.”     (Quoting 
    id. at 229.)
          Nautilus contends
    that in this case, based on its additional insureds provision,
    Nautilus’s duty to defend VP & PK could have similarly been
    deferred until Kila Kila’s negligence was determined in the
    underlying case, and that, until such a determination was made,
    Lexington would have been obligated to defend VP & PK.
    Nautilus also alleges that Lexington wrongly assumed
    that it was an excess insurer pursuant to its “Other Insurance”
    clause. In Nautilus’s view, “Lexington was primary as to the
    liability of its named insured, and could have been primary
    throughout the entire defense[,]” because Nautilus’s Additional
    Insured Endorsement did not even apply until Kila Kila was found
    negligent.   According to Nautilus, it had the right to place
    conditions on its additional insured endorsement obligation, and
    if those conditions were not met, then VP & PK would not have
    been an additional insured to Nautilus’s policy.
    Moreover, Nautlius alleges that “[if] members of the
    Hawai#i Supreme Court can come to two different interpretations
    with respect to the same insurance policy,” as they did in Dairy
    Road Partners, where two justices dissented to the majority’s
    interpretation of the business automobile liability policy,
    19
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    “surely Lexington can appreciate the possibility that when it
    interpreted Nautilus’ policy that there may be an interpretation
    of the policy that was different from its own interpretation.”
    As a policy matter, Nautilus maintains that, “[b]ased on the
    complexity of an insurance policy, an insurer should not be
    allowed to look at another insurer’s policy when deciding whether
    or not the insurer owes its insured a duty to defend.”
    As to the significance of the limitations on Nautilus’s
    “Additional insured Endorsement,” Lexington argues that it does
    not matter whether it was conditioned on Kila Kila’s negligence,
    because there were allegations in the underlying action that Kila
    Kila had been negligent, and Nautilus had a duty to defend based
    on those allegations.     According to Lexington, “[j]ust because it
    was later determin[ed] that Kila Kila was not negligent, does not
    negate Nautilus’ duty to defend.”
    Lexington avers that, by operation of its “Other
    Insurance” provision, Nautilus was the primary insurer of VP &
    PK, and was defending, and therefore Lexington had no duty as an
    excess insurer to defend under the circumstances.           Lexington
    distinguishes Cati, Inc. on the basis that the additional insured
    provision in that case was worded differently than Nautilus’s
    Additional Insured Endorsement.       In Cati, Inc., the policy
    provided that “additional insured coverage will be primary only
    if the underlying claim is determined to be solely as a result of
    20
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    the negligence or responsibility of the named insured[,]” (some
    emphasis omitted) (quoting Cati, 
    Inc., 302 A.D.2d at 229
    ),
    whereas Nautilus’s Additional Insured Endorsement does not
    contain that specific contingent language.         Therefore, Lexington
    asserts, because there was negligence on the part of Kila Kila
    alleged in the underlying action, Nautilus “had the primary duty
    to defend as determined at the outset pursuant to the language of
    the Additional Insured Endorsement and Hawai#i law.”
    In its Reply Brief, Nautilus responds that in a
    coverage dispute all relevant insurance policies may be
    considered, but that when an insurer is determining its duty to
    defend its insured, “[t]he fact that there is another insurer
    providing a defense to the insured is irrelevant [because] [a]n
    insurance policy between an insurer and its insured is personal.”
    Nautilus argues that allowing one insurer to look at another
    insurer’s policy would increase the risk of prejudice, for
    example, should the insurer misinterpret another insurer’s
    policy.   Nautilus explains that, illustrative of such, Lexington
    has misinterpreted Nautilus’s Additional Insured endorsement to
    be contingent on “alleged negligence” when in actuality it is
    contingent on “actual negligence.”        According to Nautilus, if
    Lexington’s interpretation of the Additional Insured Endorsement
    were accurate, then Nautilus would have had to pay the judgment
    against VP & PK so long as the complaint alleged negligence
    21
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    against Kila Kila, regardless of whether the jury found Kila Kila
    to actually be negligent.
    Nautilus also counters Lexington’s argument that
    limiting an insurer’s ability to consider other insurance
    policies would render “other insurance” provisions meaningless.
    Nautilus avers that “other insurance” clauses, like the one in
    Lexington’s policy, relate to the duty to indemnify, rather than
    the duty to defend. The duty to indemnify would not be affected
    by any limitations on what an insurer can consider in deciding
    whether it has the duty to defend.
    3.
    In recognition of the fact that the duty to defend is
    broader than the duty to indemnify, Hart v. Ticor Title Ins. Co.,
    126 Hawai#i 448, 458, 
    272 P.3d 1215
    , 1225 (2012), courts have
    held that “if an exclusion may operate to relieve an insurer of
    its duty to indemnify and the applicability of the exclusion
    cannot be determined until after a trial, the insurer must defend
    the underlying suit.”     Ostrager & Newman, Insurance Coverage
    Disputes   § 5.02(a), at 312.      Nautlius’ argument is that since
    the “other insurance” provision in Lexington’s policy would
    operate to relieve Lexington of its duty to indemnify only if
    Kila Kila was negligent, an issue to be determined at trial,
    Lexington had the duty to defend the underlying suit.

    C.
    Ultimately, in deciding whether insurers may look to
    other policies in disclaiming the duty to defend, we rely on
    policy considerations behind why the duty to defend exists,
    including what options are available to insurers, Hawai#i
    jurisprudence on the duty to defend, the possible risks in
    allowing insurers to disclaim their duty based on other policies,
    and the reasonable expectations of insureds.
    We have observed that “insurers have the same rights as
    individuals to limit their liability[] and to impose whatever
    conditions they please on their obligation, provided they are not
    in contravention of statutory inhibitions or public policy.”

    665 P.2d 648
    , 655 (1983) (internal citations and quotation marks
    omitted).    On the other hand, however, we have long held that any
    ambiguities in an insurance contract regarding coverage are
    resolved in favor of the insured as against the insurer.            See
    Tri-S Corp. v. W. World Ins. Co., 110 Hawai#i 473, 489,

    99 P.3d 96

    should be resolved in favor of the insured); Estate of Doe v.

    ambiguities against the insurer”); see also Allstate Ins. Co. v.

    186 P.3d 609
    (2008) (applying these
    principles in interpreting ambiguous language in an insurance
    contract exclusion).
    When it comes to the duty to defend, a heavy burden is
    placed on the insurer if that insurer wishes to disclaim its
    duty.   To reiterate, “‘the duty to defend rests primarily on the
    possibility that coverage exists.’”        Tri-S Corp., 110 Hawai#i at
    
    488, 135 P.3d at 97
    (emphasis in original) (quoting Dairy Road
    Partners, 92 Hawai#i at 
    412, 992 P.2d at 107
    ).          Furthermore, to
    reiterate, all doubts as to a duty to defend are resolved against
    the insurer and in favor of the insured.         
    Id. “The contractual
    obligation to defend is triggered by
    the insured tendering the defense to the insurer.”           22 Appleman §
    136.1, at 8.   If an insurer is not certain as to whether coverage
    exists, there are several options available to that insurer.               The
    insurer may file a declaratory judgment action to determine
    whether it is required to defend, it can defend under a non-
    waiver agreement or reservation of rights, or it can refuse to
    defend and risk the consequences.        22 Appleman § 136.7, at 45.
    The first of these options enables an insurer to
    establish in a court action whether it must defend.           This permits
    24
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    an insurer to determine coverage issues, “allowing the insurer to
    address the limits of its duty to defend without risking a later
    finding that it acted in bad faith.”         
    Id. at 50.
        However, as
    will be explained, an otherwise primary insurer may not disclaim
    its duty to defend on the basis of a general “other insurance”
    provision.7    By requiring that a primary insurer have the duty to
    defend, regardless of its “other insurance” clause, an insured
    will be ensured a defense where he or she may be entitled to one.
    The second option, defending under a non-waiver
    agreement or reservation of rights, permits an insured to
    “satisfy its duty to defend the policyholder while simultaneously
    preserving its ability to rely later on any available policy
    defenses that might have vitiated the duty.”           Id.; see AIG Hawaii
    Ins. Co., Inc. v. Smith, 78 Hawai#i 174, 179-80, 
    891 P.2d 261
    ,
    266-67 (1995) (discussing the validity of a reservation of rights
    by the insurer in connection with tendering a defense).             It has
    been explained that “[a] reservation of rights agreement is
    notice by the insurer to the insured that the insurer will defend
    the insured but that the insurer is not waiving any defenses
    . . . it may have under the policy.”         First Ins. Co. v. Hawaii,
    Inc. v. 
    State, 66 Haw. at 422
    , 665 P.2d at 654 (internal

    Of course, where one insurance policy explicitly contemplates the
    operation of another specifically named policy by reference, the insurer will
    not be looking outside its own policy, and therefore may look to that named
    policy in disclaiming its duty to defend.
    25
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    quotation marks and citation omitted).         In the event that it is
    later determined that the insurer had no duty to defend, the
    insurer may recoup its expenses from the insured.           See 22
    Appleman § 136.7, at 46.
    This ability of an insurer to tender a defense under a
    reservation of rights, without necessarily acceding to the notion
    that its policy provides coverage, supports the conclusion that
    insurers should not be permitted to look to other policies in
    disclaiming the duty to defend.       Insofar as an insurer may
    believe that another policy provides coverage, in lieu of its
    policy, that insurer may tender a defense under a reservation of
    rights -- leaving open the possibility that another insurer may
    be ultimately   responsible for the costs of coverage.
    It is the third of these options -- an insurer refusing
    to defend and risking the consequences -- that we hope to avoid
    in situations where the insurer would be primary, except by
    operation of its “other insurance” clause.         Where an insured has
    contracted for primary insurance, an insurer should not be able
    to refuse to defend and place the risk on the insured, of the
    insurer’s erroneous understanding of another insurance policy
    that is not part of the original contract.         Instead, all primary
    carriers should be involved in the initial proceedings where the
    complaint alleges facts within the scope of coverage.            See Dairy
    Road Partners, 92 Hawai#i at 
    422, 992 P.2d at 117
    .
    26
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    In Hawai#i, it has been established that insurers may
    look to the facts of the complaint8 and their own policies in
    determining whether they have the duty to defend a particular
    action.   In Lexington’s view, insurance companies should be able
    to interpret other policies as well in disclaiming the duty to
    defend.   The danger in this approach, as Nautilus points out, is
    that the insurance company may misinterpret the other policy in
    disclaiming its duty.      Of course, an insurer may misinterpret its
    own policy, but misinterpretation may be of a greater risk where
    the insurer is examining a contract to which it is not a party.
    We have held that “[t]o ascertain whether coverage
    exists in insurance coverage disputes, we must look to the
    language of the insurance policy consistent with the insurer and
    insured’s intent and expectations.”         Methven-Abreu v. Hawaiian
    Ins. & Guar. Co., 
    73 Haw. 385

    particular “other” contract may not be able to accurately
    ascertain the expectations of the insurer and insured who are the
    actual parties to the other contract.
    Moreover, the relationship between the insured and its
    primary insurer with respect to the duty to defend is a personal
    one.    See, e.g., Am. Fid. & Cas. Co. v. Penn. Thresherman &
    Farmers’ Mut. Cas. Ins. Co., 
    280 F.2d 453
    , 459 (5th Cir. 1960)
    (stating that “the duty to defend is one which is personal to the
    relationship of [the] insurer and [the] assured”).              The insured
    chose a particular insurer as its primary insurer, and as such, the
    insured has the reasonable expectation that that insurer will come
    to the insured’s defense where coverage is applicable.               See Dairy
    Road Partners, 92 Hawai#i at 
    422, 992 P.2d at 117
    ; Commerce & Indus,
    Ins. Co. v. Bank of Hawai#i, 
    73 Haw. 322
    , 327, 
    832 P.2d 733
    , 736
    (1992) (“An insurer has a duty to proceed in defense of a suit, at
    least to the point of establishing that liability upon which
    plaintiff was relying was in fact not covered by the policy, and
    not that it merely might not be.” (internal quotation marks and
    citation omitted)).
    Accordingly, where an insured has contracted for primary
    insurance, that insured should be entitled to a defense by its
    insurer.     See Hawaiian Holiday Macadamia Nut Co. v. Indust. Indem.
    Co., 76 Hawai#i 166, 169, 
    872 P.2d 230
    (1994) (holding that the
    “insurer’s duty to defend its insured is contractual in nature”).
    28
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    In General Motors Acceptance Corp. v. Nationwide Insurance Co., 
    828 N.E.2d 959
    (N.Y. 2005), for example, the New York Court of Appeals
    addressed a similar situation where there were two coincidental
    primary insurance policies, but where one was deemed “excess” by
    the operation of an “other insurance” 
    clause. 828 N.E.2d at 962
    .
    That court reasoned that “[p]rimary insurance premiums are based,
    at least in part, on the insurer’s consideration that it may be
    liable to defend an action[,]” and held that “[r]elieving primary
    insurers of the duty to defend would provide a windfall to the
    carrier insofar as the costs of defense -- litigation insurance --
    are contemplated by, and reflected in, the premiums charged for
    primary coverage.”       
    Id. Therefore, we
    hold that a primary insurer may not look to
    another insurance policy in disclaiming its duty to defend.                 If a
    primary insurer is tendered a defense, and believes that it is
    actually an excess insurer or otherwise has no duty to defend by
    operation of its “other insurance” clause, then that primary
    insurer must still defend in the action.          This is the appropriate
    remedy, rather than leaving the defense up to other insurers or,
    potentially up to the insured, where the insured has contracted for
    primary insurance coverage.9       The options available for a primary

    However, where an insurer holds a true excess policy, then the
    parties have bargained for excess insurance. As noted, in many of these true
    excess policies, the other applicable primary insurance is specifically
    listed, and such policies are designed to provide coverage over and above

    insurer that believes it has been rendered an excess insurer by the
    operation of its “other insurance” clause are discussed below.
    III.
    Question 2:     Whether an “other insurance” clause that
    purports to release an otherwise primary insurer of the duty to
    defend if the insurer becomes excess as to liability is
    enforceable.
    A.
    As to this question, the bulk of Nautilus’s arguments
    are premised on the specific provisions of Lexington’s policy,
    rather than as addressed toward the more general question posed
    by the Ninth Circuit to this court.          Nautilus avers that
    Lexington’s “Other Insurance” clause violated “‘the rule the
    insurance provisions that take away or limit coverage must be
    conspicuous, plain, and clear.’”          (Quoting Carmel Dev. Co. v. RLI
    Ins. Co., 
    126 Cal. App. 4th 502
    , 516 (2005).)           It reiterates that
    Lexington’s “Other Insurance Clause” is contingent on the outcome
    at trial, and since Kila Kila was found not to be negligent,
    9
    (...continued)
    other existing primary policies. See 23 Appleman § 145.1, at 5 (“[I]n
    contrast to primary policies, a pure excess policy provides specific coverage
    above an underlying limit of primary insurance and often will refer directly
    within the excess policy declaration and policy itself to primary insurers as
    well as other excess insurers.”). In such cases, an insurer may look to other
    insurance policies in disclaiming its duty to defend in order to avoid
    needless litigation either in the form of declaratory judgment actions, or
    contribution of defense costs after the fact, where the insured did not
    bargain for primary coverage from that insurer in the first instance, as was
    explicitly considered in the contract between the insurer and insured.
    30
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Nautilus was not responsible for any loss and therefore VP & PK
    had no “other valid and collectible insurance.”           Nautilus further
    argues that Lexington’s “Other Insurance” clause should be
    interpreted to limit indemnification only.         As to “Other
    Insurance” clauses generally, however, Nautilus does posit that
    an “Other Insurance” clause that purports to release an otherwise
    primary insurer of the duty to defend if the insurer becomes
    excess as to liability should not be enforceable because it
    “fails to give the insured adequate notice that it may not
    receive a defense it believed it bargained for” and “blurs the
    distinction between an insurer’s duty to defend and duty to
    indemnify.”
    In response, Lexington alleges that there is no public
    policy against enforcement of “other insurance” provisions, and
    that the ICA has recognized the utility of excess “other
    insurance” clauses in the context of uninsured motorist
    insurance.    Liberty Mut. Ins. 
    Co, 120 Haw. at 353-354
    , 205 P.3d
    at 618-19.    Lexington maintains that under California law,
    federal and state courts routinely enforce excess other insurance
    clauses in the absence of prejudice to the insured.           (Citing
    Fireman’s Fund Ins. Co. v. Md. Cas. Co., 
    65 Cal. App. 4th 1279
    ,
    1304 (1998) (“The courts will generally honor the language of
    excess ‘other insurance’ clauses when no prejudice to the
    interests of the insured will ensue.”).)         Lexington avers that
    31
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    the insured in this case was not prejudiced by the enforcement of
    the “other insurance” clause, and was not left without a defense
    due to the circularity of other insurance provisions.             Lexington
    also declares that the placement of its clause does not violate
    “the rule that insurance provisions that take away or limit
    coverage must be conspicuous, plain, and clear”, that if Nautilus
    had refused to defend VP & PK, Lexington would have defended
    under the terms of its policy and contrary to Nautilus’s
    suggestion, the insured would not be left “in a lurch”.
    In its Reply Brief, Nautilus reiterates that
    “[i]nsureds should not be left to wonder if the carriers that
    they have been paying premium rates to may or may not come to
    their defense because they have been added on to another policy
    as an additional insured.” As a policy matter, Nautilus suggests
    that “[i]f insureds are added on as additional insureds on
    another policy, let the insureds reap the benefits, not the
    insurance companies who have been receiving premiums to provide
    primary coverage.”

    In Liberty Mutual Insurance Co., the ICA majority10
    10
    The Honorable Corinne K.A. Watanabe filed an opinion dissenting in
    part, holding that the excess “other insurance” clause “invalidly limited
    Liberty Mutual’s [uninsured motorist] liability, as defined by Hawai#i
    statutes and case law, is against public policy and is, therefore void and
    (continued...)
    32
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    addressed an “other insurance” clause of an insurance policy
    sharing some characteristics with the type of policy described in
    the Ninth Circuit’s certified question -- specifically, it made
    the named insurer into an excess insurer if there was any other
    collectible insurance, under certain circumstances.            120 Hawai#i
    at 345, 
    349, 205 P.3d at 610
    , 614.         The “Other Insurance”
    provision in Liberty Mutual’s policy stated, in part, that “any
    insurance we [Liberty Mutual] provide with respect to a vehicle
    you [the named insured] do not own shall be excess over any other
    collectible insurance.”      
    Id. at 345,
    205 P.3d at 610 (emphases
    added).   Thus, as with the “Other Insurance” provision presented
    in this case, the Liberty Mutual provision transformed some of
    its apparently primary coverage into excess coverage, if there
    was other collectible insurance available.          See 
    id. Rather than
    the duty to defend, the question in Liberty
    Mutual Insurance Co. was whether Liberty Mutual was required to
    pay for uninsured motorist benefits as a primary insurer or as an
    excess insurer.     
    Id. at 336,
    205 P.3d at 601.        In addressing this
    issue, the ICA referred to policy considerations, and also
    considered the statutory scheme governing automobile insurance
    coverage, which is not at issue in this case.           The ICA majority

    unenforceable.” Liberty Mut. Ins. Co., 120 Hawai#i at

    (Watanabe, J., dissenting in part).
    33
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    upheld the excess “other insurance” clause in Liberty Mutual’s
    policy, stating that “such clauses serve valid purposes, such as
    helping to keep costs of premiums down[,]” and that “[b]y
    allowing insurance companies to set the priority of payment
    through excess provisions, they are better able to assess the
    risk of providing the coverage and to charge the insured
    accordingly.”     
    Id. at 353,
    205 P.3d at 619.
    2.
    This case presents a different question, however, in
    that Liberty Mutual Insurance Co. considered an excess “other
    insurance” clause in the context of the duty to indemnify -- and
    here we consider the validity of that type of provision when it
    allows the insurer to escape or become excess11 as to the duty to
    defend where the insurer is excess as to liability.            In the
    
    discussion supra
    , it was explained how the duty to defend is
    broader than the duty to indemnify, Hart, 126 Hawai#i at 
    458, 272 P.3d at 1225
    , and in accordance with that axiom, Nautilus urges
    us to make unenforceable any clauses relieving the primary
    insurer of the duty to defend if the insurer becomes excess as to
    liability.
    11
    Lexington avers that the operation of its “other insurance” clause
    makes it only excess as to the duty to defend, and does not allow it to escape
    the duty to defend entirely when it becomes excess as to liability. Both
    situations are addressed herein, and the same result would apply in either
    situation.
    34
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    However, in light of our holding as to the first
    certified question, we conclude that we need not render those
    clauses completely unenforceable.        Instead, we simply reiterate
    that a primary insurer has the initial duty to defend, regardless
    of any “other insurance” provision purporting to relieve that
    insurer of the duty to defend if it is deemed excess as to
    liability, but that an insurer may enforce such an “other
    insurance” clause when obtaining equitable contribution or
    reimbursement for defense costs where it believes that it has
    been made excess by operation of an “other insurance” clause.
    This result is consistent with the expectations of the
    insured, specifically that where the insured is paying for
    primary insurance, it will be defended where there is a
    possibility of coverage.      See Dairy Road Partners, 92 Hawai#i at
    
    412, 992 P.3d at 107
    .     The insured will not be “left in a lurch,”
    as Nautilus avers, because the primary insurer, regardless of its
    “other insurance” clause, will have a responsibility to defend.
    Moreover, while such clauses may not be used to allow an
    otherwise primary insurer to refuse to tender a defense
    altogether, they will be enforced to achieve an equitable result
    between two or more insurance companies, an approach that allows
    the terms of the contract to take effect, without placing an
    undue burden on the insured.       Cf. Sentinel Ins. Co., 76 Hawai#i
    at 
    302, 875 P.2d at 919
    (holding that under the circumstances of
    35
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    the case, “[e]quity . . . dictates that the court allocate
    contribution among liable insurers in proportion to the time
    periods their policies covered”).
    We note that some courts have held that if a primary
    insurer undertakes the insured’s defense, it may not seek
    reimbursement from another primary insurer, on the grounds that
    there is no contractual relationship between the two insurers and
    that the defending insurer was undertaking duties consistent with
    its contract with the insured.       22 Appleman § 136.10 at 80-81;
    see, e.g., Jostens, Inc. v. Mission Ins. Co., 
    387 N.W.2d 161
    , 166
    (Minn. 1986) (“This court has held that when there is a bona fide
    dispute between two carriers with overlapping coverages as to
    which is primary, whichever undertakes to defend cannot pass on
    its defense expense to the other carrier.”).          However, we
    conclude that the better approach is to allow one insurer to
    obtain contribution from another co-insurer that is also
    contractually obligated to defend the insured.          See Nat’l Indem.
    Co. v. St. Paul Ins. Co., 
    724 P.2d 544
    , 544-45 (Ariz. 1986)
    (“When an insurer has a duty to defend the insured, there should
    be no reward to the insurer for breaching that duty.            A breach of
    the obligation to defend should not be encouraged, but the rule
    which allows an insurer to avoid the costs of defense tends to
    encourage an avoidance of the insurer’s responsibilities.”).
    This contribution or reimbursement shall be in accordance with
    36
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    all contract terms, including those purporting to make one
    insurer excess to the other where “other insurance” is
    available.12
    As to the Ninth Circuit’s second certified question, we
    therefore answer “yes”, but conditionally.          “Other insurance”
    clauses purporting to relieve the insurer of the duty to defend
    if the insurer becomes excess as to liability are enforceable,
    but only in an action between two or more insurers for recovery
    of defense costs.
    IV.
    Question 3:    Whether the irreconcilability of “other
    insurance” provisions in otherwise primary insurance policies
    should be determined before or after the operation of the “other
    insurance” provisions is determined.
    The “irreconcilability” referenced by the Ninth Circuit
    in this question is the concept, mentioned above, that “other
    insurance” provisions may become irreconcilable, or mutually
    repugnant, where identical clauses are presented in two primary
    liability policies.      “When both policies contain ‘other
    insurance’ clauses which provide that the coverage afforded shall
    be deemed excess insurance if other insurance exists to cover the
    12
    As will be discussed infra, where both primary insurers have
    “other insurance” clauses purporting to relieve them of the duty to defend,
    such clauses are irreconcilable, or “mutually repugnant” and therefore will
    not be enforced, leaving both insurers as primary insurers for purposes of
    cost allocation.
    37
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    loss, most courts hold that the excess clauses operate to cancel
    each other out and the policies of both insurers must be
    considered primary insurance.”       Ostrager & Newman, 2 Handbook on
    Insurance Coverage Disputes § 11.03, at 1001.
    A.
    Nautilus argues that it should be first determined
    whether the two policies insured against the same risk at the
    same level of coverage, then determine whether or not the two
    policies conflict, and only then determine the operation of the
    “Other Insurance” provisions.       According to Nautilus, the two
    policies in this case did not insure against the same risk at the
    same level of coverage, and so there was no need to determine
    whether the policies conflict.       Nautilus further alleges that,
    even assuming that the two policies did provide the same level of
    coverage, the policies contain almost identical “other insurance”
    language and therefore are irreconcilable.         Finally, Nautilus
    contends that the operation of the “other insurance” provisions
    should be determined last because until it has been determined
    that there is a “loss”, which is typically determined at the end
    of the underlying lawsuit, it is not necessary to determine the
    operation of the “other insurance” provisions.
    Lexington responds that a court should first determine
    whether “other insurance” provisions in two policies actually
    conflict.    In Lexington’s view, “[t]he rule of repugnancy should
    38
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    only apply if there is an actual conflict between the two “other
    insurance” clauses,” and here, there was no such conflict.
    (Citation omitted.) (Emphasis in original.)          Contrary to
    Nautilus’s argument, Lexington maintains that there is no need to
    decide whether there is the same level of coverage or level of
    risk between the two policies, because the duty to defend does
    not require this determination.       Instead, Lexington notes,
    “‘other insurance’ provisions must be reviewed at the inception
    of litigation,” because “[i]f there is a covered claim . . .
    then there is a duty to defend; but then where there are multiple
    insurers, then the policy language, the contractual language,
    must be reviewed and analyzed to determine if there is a priority
    or primary in that defense.”
    B.
    As noted, the majority view is that “other insurance”
    policies that are irreconcilable, or “mutually repugnant” will
    negate each other, and neither will be enforced.           See Liberty
    Mut. Ins. Co., 120 Hawai#i at 354, 
    n.23, 205 P.3d at 619
    n.23
    (explaining, but not applying, this concept).          The underlying
    proposition is that where both policies have identical “other
    insurance” provisions which provide that the coverage afforded
    will be deemed excess insurance if other insurance exists to
    cover the loss (or tender a defense), these excess clauses
    operate to “cancel each other out”, and the policies of both
    39
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    insurers must be considered primary insurance.           See, e.g., CSE
    Ins. Grp. v. Northbrook Prop. & Cas. Co., 
    23 Cal. App. 4th 1839
    (1994); Empire Cas. Co. v. St. Paul Fire & Marine Ins. Co., 
    764 P.2d 1191
    , 1199 (Colo. 1998); Universal Underwriters Ins. Co. v.
    Allstate Ins. Co., 
    592 A.2d 515
    , 517 (N.H. 1991).            Put another
    way, if each excess clause was given effect, neither policy would
    provide primary coverage.13      See, e.g., Fed. Ins. Co. v. Atl.
    Nat’l Ins. Co., 
    250 N.E.2d 193
    (N.Y. 1969).
    Setting the issue of irreconcilability aside
    temporarily, we note that although both policies in this case
    contain an “other insurance clause,” by their operation the
    clauses do not create a scenario in which the two policies would
    “cancel each other out” and neither would provide primary
    coverage.    Only Lexington’s “other insurance” provision could
    potentially take effect in this case, because VP & PK was added
    as an “additional insured” onto Nautilus’s policy.            By contrast,
    the “other insurance” provision in Nautilus’s policy would not
    have taken effect because Kila Kila was not an “additional
    insured” on Lexington’s policy.        By adding VP & PK as an
    “additional insured” under certain circumstances, Nautlilus
    understood that it may have had to provide coverage for VP & PK.
    13
    This same reasoning applies where two or more primary policies
    contain “escape” clauses, which, if both were enforced, would deprive the
    insured of all coverage. See 22 Appleman § 140.3, at 399.
    40
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Presumably this consideration was taken into account as part of
    the premiums that Nautilus charged to Kila Kila.
    These circumstances are distinguishable from the
    situation argued by Nautilus in its briefs.          A more typical
    situation arises where there is one insured and two insurance
    companies, and both insurance companies are deemed excess by
    operation of the “other insurance” provisions, thereby leaving
    the insured with no primary insurance.         Here, instead, VP & PK
    will either be covered by Nautilus as a primary insurer, because
    it is listed as an “additional insured” on Nautilus’s policy, or,
    the “additional insured” provision will not come into play, so VP
    & PK will not be covered by Nautilus, and therefore, the “other
    insurance” provision in Lexington’s policy will not be triggered,
    and Lexington will remain the primary insurer.
    Where it is possible to avoid a finding of “mutual
    repugnance” altogether, therefore, it should be determined from
    the face of the two policies, and the allegations in the
    complaint, whether such allegedly “mutually repugnant” clauses
    are actually relevant before both clauses are deemed inoperable.
    For example, it has been explained that “[w]hen only one of two
    policies co-insuring the same loss contains an ‘other insurance”
    clause, courts generally will give effect to the ‘other
    insurance’ provision (if it is not contrary to statute or public
    policy).”    Ostrager & Newman, 2 Handbook on Insurance Coverage
    41
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Disputes § 11.03[b], at 999.       This rule seeks to effectuate the
    intent of the insurers and avoid cancelling out contract terms
    that need not be voided.      Similarly, when only one of the “other
    insurance” clauses in two or more policies would be relevant in a
    given case based on the terms of the clause and the allegations
    in the underlying case, the clause that does become operational
    should be given effect.
    This is not to say, however, that the full operation of
    the clauses must be determined before irreconcilability may be
    considered.   For example, here, there is a dispute about whether
    VP & PK was actually covered as an “additional insured” under
    Nautilus’s policy, based on the issue of Kila Kila’s negligence,
    which was resolved only in the underlying trial.           A court looking
    at the insurance contracts at any time prior to the conclusion in
    the underlying litigation would not necessarily be able to
    ascertain whether Lexington’s “other insurance” would actually
    become fully operational.      However, in this case one would be
    able to determine whether the clauses would even be relevant by
    looking at the face of the contracts and the allegations of the
    complaint.    Lexington’s clause is relevant and Nautilus’s is not.
    Based on this preliminary determination, there would be no need
    to consider irreconcilability or mutual repugnance.
    By determining whether an “other insurance” clause is
    triggered first, a court may be able to avoid irreconcilability
    42
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    or mutual repugnance, such as in this case, and better effectuate
    the contract language.     This is consistent with the principle
    that “[i]nsurance policies are subject to the general rules of
    contract construction,” and thus, “the court must . . . respect
    the plain terms of the policy and not create ambiguity where none
    exists.”   First Ins. Co. of Hawai#i, 
    Inc., 66 Haw. at 423-24
    , 665
    P.2d at 655 (alteration in original) (internal brackets,
    citations, and quotation marks omitted).         We hold, therefore,
    that it must first be determined whether two or more “other
    insurance” provisions are relevant, based on the face of the
    policies and the complaint, and only then must it be decided
    whether the provisions are irreconcilable.         The complete
    operation of the “other insurance” clauses may be resolved
    thereafter.
    V.
    Question 4:    Whether, and when, an excess insurer, or
    otherwise primary insurer who becomes an excess insurer by
    operation of an “other insurance” clause, has a duty to defend.
    A.
    1.
    As to this question, as noted before, Nautilus avers
    that a primary insurer who becomes an excess insurer by operation
    of an “Other Insurance” clause has the duty to defend its insured
    because “the duty to defend is one which is personal to the
    43
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    relationship of [the] insurer and [the insured].”           Nautilus
    analogizes the facts to those of American Fidelity & Casualty
    Co., where, according to Nautilus, two individuals, Clay and
    Britt, were covered by two different insurers.          
    (Citing 280 F.2d at 455
    .)   “American” was Clay’s primary insurer and
    “Pennsylvania” was Britt’s primary insurer.          (Citing id.)
    American brought an action seeking a declaration that it did not
    have a duty to defend Clay, because Clay was an additional
    insured under the insurance policy between Britt and
    Pennsylvania.   (Citing 
    id. at 457.)
    American’s argument was based on the “other insurance”
    clause in its policy, which American alleged rendered its policy
    excess and Pennsylvania’s primary, thus relieving American of any
    duty to defend Clay until Pennslyvania had exhausted its policy
    limitations in doing so.      (Citing 
    id. at 456-57,
    456 n.4.)
    Nautilus refers to the Fifth Circuit’s holding stating that
    American was incorrect in believing that based on the “other
    insurance” clause, “‘it was merely an ‘excess’ insurer, its duty
    to defend, like the obligation to pay, was excess also.’”
    (Quoting 
    id. at 458.)
        The Fifth Circuit concluded that “‘there
    can be no possible basis for American’s denial of its contractual
    duty of defense.’”    (Quoting 
    id. at 457.)
    Thus, Nautilus maintains that Lexington is still
    required to defend VP & PK even if it were excess as to its
    44
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    defense obligations.     In support of this contention, Nautilus
    cites to Southern Farm Bureau Casualty Insurance Co. v. Allstate
    Insurance Co., 
    150 F. Supp. 216
    (W.D. Ark. 1957), for the
    proposition that even where the insured’s primary insurer was
    excess to another insurer for damages, it still had the duty to
    defend the named insured, and to State Farm Mutual Automobile
    Insurance Co. v. Foundation Reserve Insurance Co., 
    431 P.2d 737
    ,
    741 (N.M. 1967), which held that even though Allstate’s insurance
    was excess, that did not relieve it of its duty to defend.             In
    Nautilus’s view, the better rule is to require a primary insurer
    who finds itself in an excess position because of an “other
    insurance” clause to defend its named insured, because this rule
    would “benefit an insured who paid for primary coverage and
    expected primary coverage,” closing loopholes that would allow an
    insurance company to “shirk its responsibility.”
    If the rule were otherwise, Nautilus points to the
    possibility for oscillating coverage in this case, where
    Lexington looked at Nautilus’s policy and concluded it was excess
    and therefore did not owe a duty to defend, but where because at
    trial Kila Kila was found not negligent, Nautilus’s policy then
    became inapplicable to VP & PK, making Lexington VP & PK’s
    primary insurer again.     Nautilus concludes that because there is
    only a possibility that a primary insurer may become excess, that
    45
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    insurer has the duty to defend regardless of what the “other
    insurance” clause may state.
    2.
    Lexington answers that by operation of its “other
    insurance” clause, it did not have a duty to defend unless and
    until Nautilus had exhausted its coverage, or unless Nautilus
    refused to defend.    Lexington avers that despite Nautilus’s
    allegations about the expectations the insured, here it is
    undisputed that VP & PK never tendered its claim to Lexington,
    but instead directly to Nautilus, “who VP & PK must have assumed
    would provide them a defense.”       Lexington states that it is “not
    asserting that it had no duty to defend, but rather by its policy
    terms, [its] duty to defend was excess to Nautilus’s duty under
    [both insurance companies’] policy language.”
    According to Lexington, some courts hold to the
    contrary of the Fifth Circuit’s decision in American & Casualty
    Co., with respect to the respective duties that subsist among one
    or more otherwise primary liability insurers.          Lexington
    maintains that the better approach is to “follow those courts
    that give effect to or reconcile competing clauses dealing with
    the existence of other insurance, at least where the insured is
    being provided a defense by one or more of its carriers.”             In
    connection with this proposal, Lexington cites to United States
    Fidelity & Guaranty Co. v. Federated Rural Electric Insurance
    46
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    Corp., 
    37 P.3d 828
    (Okla. 2001), for the proposition that
    “‘[W]here an insured has both primary and excess liability
    insurance, the excess insurer is not responsible to participate
    in the costs of defense until after the limits of the primary
    policy are exhausted[,]’” (quoting U.S. Fid. & Guar. 
    Co., 37 P.3d at 832-33
    ), and to Western Casualty & Surety Co. v. Western World
    Insurance Co., 
    769 F.2d 381
    (7th Cir. 1985), for the view that
    “‘when one policy is primary and the other is excess, only the
    primary insurer need defend claims below the limits of the
    primary policy.”     (Quoting W. Cas. & Sur. 
    Co., 769 F.2d at 385
    ).)14
    Finally, Lexington asserts that its approach is
    consistent with the insurance law principles of “(1) honoring
    insurers’ rights to limit their liability and impose whatever
    conditions they please on their obligation, provided they are not
    in contravention of statutory inhibitions or public policy; and
    (2) that every insurance contract shall be construed according to
    the entirety of its terms and conditions as set forth in the
    policy.”    Lexington also points out that there is no prejudice to
    14
    Lexington also cites Liberty Mutual Insurance Co. v. Pacific
    Indemnity Co., 
    579 F. Supp. 140
    , 145 (W.D. Pa. 1984), Continental Casualty Co.

    the insured, apparently under terms such as those at issue in
    this case, “because it must be and will be defended.”
    3.
    Nautilus replies that the cases cited by Lexington in
    support of its position are not applicable to this case.
    Nautilus argues that United States Fiduciary & Guarantee Co.
    dealt with a true excess carrier, not one who becomes excess
    through an “other insurance” provision, and that similarly,
    Pacific Indemnity Co. dealt with “true excess” insurers.
    Additionally, it states that Continental Casualty Co., Hartford
    Accident & Indemnity Co., and U.S. Fire Insurance Co. do not
    involve an additional insured issue.
    With respect to the Seventh Circuit’s decision in
    Western Casualty & Sururety Co., Nautilus maintains that that
    case supports its position that Lexington owed a duty to defend.
    According to Nautilus, Western Casualty & Sururety Co. held that
    “‘when a case is settled the claims of the two insurers must be
    resolved according to the terms of the excess clauses.’”
    (Quoting W. Cas. & Sur. 
    Co., 769 F.2d at 385
    .)          Nautilus points
    out the hypothetical Western Casualty & Sururety Co., regarding
    the possible outcome had that case gone to trial, and “the
    judgment revealed” that the first primary insurer did not cover
    the “loss”, then that court may have allowed that primary insurer
    to recover from a second primary insurer who had been deemed
    48
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    excess because there was other primary insurance covering the
    “loss”.   (Citing 
    id. at 386.)
         Nautilus says that it, like the
    first primary insurer in the hypothetical, did not cover the
    “loss” and therefore Nautilus should be able to recover the costs
    of defense from Lexington.
    B.
    In response to this certified question, we hold that
    an otherwise primary insurer who becomes an excess insurer by
    operation of an “other insurance” clause owes the duty to defend
    from the time the defense is tendered.         “[T]he duty to defend
    must be determined when the claim is initially asserted.”             Hart,
    126 Hawai#i at 
    458, 272 P.3d at 1225
    (internal quotation marks
    and citation omitted).
    1.
    Our disposition as to the first question essentially
    resolves this question as well -- because we hold that primary
    insurers who could allegedly become excess insurers by operation
    of an “other insurance” clause are not permitted to look to other
    policies when determining whether they have a duty to defend.
    Therefore, the duty to defend will arise as if they are the
    primary insurers, inasmuch as they have not yet been deemed an
    “excess insurer” by operation of the “other insurance” provision.
    Pursuant to our holding herein, only if an otherwise primary
    insurer is deemed an “excess insurer” in an action seeking
    49
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    contribution or reimbursement of defense costs may that insurer
    look to the operation of an “other insurance” clause making it
    excess.
    As to question 2, we held that “other insurance”
    clauses purporting to release an otherwise primary insurer of its
    duty to defend if it becomes excess as to liability are
    enforceable in certain circumstances.        However, the question of
    liability cannot be determined until after the conclusion of
    litigation (or sometimes at all, in the event that the case
    settles).    “[A]n insurer’s ultimate non-liability should not free
    it from its concurrent and distinct contractual duty to defend.”
    
    Id. (internal quotation
    marks and citation omitted).            Therefore,
    the duty to defend may not be disclaimed by an otherwise primary
    insurance carrier during the proceedings on the basis of a clause
    purporting to make that insurer excess.
    The instant case illustrates the problem with allowing
    an insurer to disclaim the duty to defend at any time before the
    conclusion of the litigation based on such a clause.            For
    example, the underlying litigation has been concluded in this
    case, and it does not appear that Lexington can actually be
    deemed an “excess insurer”.      As 
    explained supra
    , Lexington can
    only be an excess insurer if VP & PK is covered by another
    policy.   VP & PK is covered by Nautilus’s policy only for
    occurrences arising out of Kila Kila’s negligence.           Kila Kila was
    50
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    found not to be negligent in the underlying litigation.            Hence,
    the additional insured coverage of VP & PK in Nautilus’s policy
    was not operable, and, accordingly, Lexington’s “other insurance”
    policy was also not operable.       It would appear to answer the
    question presented, that Lexington, therefore, is the primary
    insurer, and Nautilus should be able to recover defense costs in
    full from Lexington.     None of this could necessarily have been
    determined before the close of litigation, however, since VP &
    PK’s indemnity coverage was dependent upon a particular finding.
    As 
    explained supra
    , our case law holds that the duty to
    defense arises where there is a mere possibility of coverage.
    See Dairy Road Partners, 92 Hawai#i at 
    413, 992 P.2d at 108
    .
    Extrapolating from this principle, we conclude that where it
    cannot be determined whether an otherwise primary insurer becomes
    an excess insurer until the conclusion of the underlying
    litigation, that an otherwise primary insurer has the duty to
    defend, from the time it receives tender of the defense.            In the
    Seventh Circuit decision cited by parties’ briefs, Western
    Casualty & Surety Co., that court stated that “[t]he state [of
    Illinois] seeks to encourage all carriers to participate in the
    initial proceedings, and as the state courts have found, it is a
    bad idea to inform insurance carriers that whichever is the least
    faithful to its obligation to the insured will escape all
    liability as long as a responsible carrier covers the loss.”               769
    51
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    F.2d at 383.    We agree that all carriers must be encouraged to
    participate in initial proceedings, and our holding as to these
    questions is intended to mandate otherwise primary insurers to
    defend and avoid uncertainty on the part of insureds as to who
    will in fact provide his, her, or its defense.
    2.
    We turn briefly to the cases cited by the parties in
    support of their respective positions.          In American Fiduciary &
    Casualty Co., cited by Nautilus, the Fifth Circuit appears to
    have reached the same conclusion that we reach herein, namely
    that where the insurance coverage of an otherwise primary insurer
    would become excess over other “valid and collectible insurance”
    by operation of an “other insurance” clause, that primary insurer
    must undertake the 
    defense. 280 F.2d at 457
    .        The Fifth Circuit
    explained that the duty to defend is one which is personal to the
    relationship of the insurer and the insured -- and as such,
    “[w]hatever may be the right ultimately to saddle off a part of
    the cost of defense actually undertaken once payment has been
    made, . . . it is contrary to the very nature of the contract
    that the insurer can scout around in hopes that it can find
    someone whose defense the [insured] is compelled to accept.”15
    15
    The Fifth Circuit does also appear to rely,   in part, on the fact
    that the “other insurance” clause at issue in that case   did not refer to the
    duty to defend. American Fiduciary & Casualty 
    Co., 280 F.2d at 459
    . As
    
    quoted supra
    , the “other insurance” clause in this case   does refer to the duty
    (continued...)
    52
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    
    Id. at 459-60
    (emphasis added).
    Lexington does not appear to dispute the holding of
    American Fiduciary & Casualty Co., but instead sets forth case
    law from other jurisdictions in support of a different approach.
    In U.S. Fiduciary & Guarantee Co., the Oklahoma Supreme Court
    held that an excess insurer has no duty to participate in defense
    
    costs. 37 P.3d at 830
    .     In that case, however, one of the
    insurance companies involved was a primary insurer and one was a
    true excess insurer, and thus it is not relevant in deciding this
    certified question.      
    Id. In Pacific
    Indemnity Co., the Western
    District of Pennsylvania held that two insurance policies
    covering the same risk both contained competing excess clauses,
    and therefore neither clause was given effect and the two
    insurers stood on equal 
    ground. 579 F. Supp. at 143
    .       The costs
    of the defense were then pro-rated in proportion with the policy
    limits of the primary policies.        
    Id. at 144.
        Thus, Pacific
    Indemnity Co. also appears not to support Lexington’s position
    because the two competing “other insurance” clauses were deemed
    irreconcilable and not given effect.         
    Id. at 143.
    In Continental Casualty Co., the California Court of
    Appeal addressed a dispute between two insurance carriers over
    15
    (...continued)
    to defend. However, the Fifth Circuit’s reasoning remains persuasive
    regardless of the presence or absence of a reference to the duty to defend in
    the “other insurance” clause.
    53
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    their respective liability for settlement of a malpractice 
    case. 134 Cal. App. 3d at 393
    .      That court construed the two “other
    insurance” clauses in the policies, where the issue was
    “conflicting excess insurance coverage[,]” 
    id. at 397,
    and
    accordingly concluded that it could “see no justification for
    choosing one policy over the other as being primarily liable for
    the excess liability.”     
    Id. Continental Casualty
    Co. thus
    allocated liability where there were irreconcilable clauses,
    unlike this case, where the issue is defense costs.
    Hartford Accident & Indemnity Co. is also inapposite,
    in that it appears to rest its holding on the fact that the
    action involved an accident with a lessee driver, where one
    insurer was the lessor’s insurer and one insurer was the driver’s
    
    insurer. 85 A.D.2d at 147
    (“There is no reason why the insurer
    of a lessor should not be required to defend against an accident
    of a lessee driver even when the driver has his own separate
    insurance coverage.”).     In U.S. Fire Insurance Co., moreover, it
    was “undisputed and uncontested” by one of the insurers that if
    both insurers’ automobile liability policies provided coverage,
    then under Texas law, its policy would be the primary policy and
    the other one would be the excess 
    policy. 772 S.W.2d at 222
    .
    Thus, the primary/excess issue had already been resolved by
    operation of Texas law, 
    id., and as
    such, U.S. Fire Insurance Co.
    is not on point.
    54
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    In the Seventh Circuit’s decision in Western Casualty &
    Surety Co., one otherwise primary insurer was deemed excess based
    on a provision in its policy deeming it excess if the insured had
    “other insurance insuring against a loss covered by this 
    policy.” 769 F.2d at 383-84
    (emphasis added).           That court’s holding
    appears to be based on the fact that the case settled, and
    therefore there was an established “loss” that would make one of
    the insurers excess.        
    Id. at 384.
        It stated that “when a case is
    settled the claims of the two insurers must be resolved according
    to the terms of the excess clauses[.]”            
    Id. at 385.
       Although the
    Seventh Circuit did explain that “when one policy is primary and
    the other is excess, only the primary insurer need defend claims
    below the limits of the primary policy[,]” this statement was in
    a context where one insurer sought compensation from the other
    for the costs of litigating and settling the suit.              
    Id. at 383,
    385.
    In sum, none of the cases cited by Lexington evince
    policy rationales that would support an approach different from
    the one we take in responding to the Ninth Circuit’s certified
    questions.      We therefore hold that the duty to defend arises at
    the outset of the litigation for an otherwise primary insurer who
    could become an excess insurer by operation of an “other
    insurance clause.”
    55
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    VI.
    Based on the foregoing, we answer the certified
    questions as follows:
    1.     Whether an insurer may look to another insurer’s policy
    in order to disclaim the duty to defend, where the complaint in
    the underlying lawsuit alleges facts within coverage.
    Unless another insurer’s policy is specifically named
    in the first insurer’s policy, an insurer may not look to another
    insurer’s policy in order to disclaim the duty to defend, where
    the complaint in the underlying lawsuit alleges facts within
    coverage.
    2.     Whether an “other insurance” clause that purports to
    release an otherwise primary insurer of the duty to defend if the
    insurer becomes excess as to liability is enforceable.
    An “other insurance” clause purporting to release an
    otherwise primary insurer of the duty to defend if the insurer
    becomes excess as to liability is enforceable, but only as
    between two or more insurers seeking to allocate or recover
    defense costs.
    3.     Whether the irreconcilability of “other insurance”
    provisions in otherwise primary insurance policies should be
    56
    ***FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER***
    determined before or after the operation of the “other insurance”
    provisions is determined.
    The relevance of the “other insurance” provisions
    should be determined from the face of the policies and the
    allegations in the complaint first.        Then, it can be decided
    whether the relevant “other insurance” provisions are
    irreconcilable or “mutually repugnant.”         If the provisions are
    reconcilable, the operation of the “other insurance” provisions
    may then be considered.
    4.   Whether, and when, an excess insurer, or an otherwise
    primary insurer who becomes an excess insurer by operation of an
    “other insurance” clause, has a duty to defend.
    An otherwise primary insurer who becomes an excess
    insurer by operation of an “other insurance” clause has a duty to
    defend as soon as a claim is tendered to it and there is the mere
    possibility that coverage of that claim exists under its policy.
