    CLARENDON NATIONAL INSURANCE COMPANY,

    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MASSACHUSETTS
    [Hon. Leo T. Sorokin, U.S. District Judge]
    Before
    Torruella, Lynch, and Kayatta,
    Circuit Judges.

    April 1, 2020
    TORRUELLA,   Circuit   Judge.       In   this   diversity   case,
    Clarendon National Insurance Company ("Clarendon") appeals the
    district court's entry of summary judgment against its claim that
    Philadelphia Indemnity Insurance Company ("Philadelphia") breached
    its contract with Lundgren Management Group, Inc. ("Lundgren")
    when Philadelphia declined to tender a defense to Lundgren, whom
    Philadelphia had insured from 2007 to 2008.         Lundgren had assigned
    these claims to Clarendon.        The district court determined that
    because the property damage allegations were excluded by the prior
    policy period exclusion, the complaint did not give rise to a duty
    to   defend.    Furthermore,      Clarendon    challenges     the   summary
    dismissal of its additional claims for contribution and alleged
    violations of Massachusetts General Laws, chapters 93A and 176D,
    which the district court concluded should also be dismissed because
    they were premised on the incorrect notion that Philadelphia had
    breached its duty to defend.         After careful consideration, we
    affirm.
    I.     Background
    A.   Factual Background
    Clarendon, a New York corporation, provided indemnity
    insurance to Lundgren, a building management corporation, from
    June 24, 2004, to June 24, 2005.         Subsequently, Philadelphia, a
    Pennsylvania corporation, provided insurance for Lundgren from
    -2-
    September 1, 2007, to September 1, 2008.            Philadelphia's insurance
    policy   with    Lundgren   contained       the   following   provision    that
    excludes coverage for damage beginning prior to the inception of
    the insurance policy:
    b. This insurance applies to "bodily injury" and
    "property damage" only if:
    . . . .
    (3) Prior to the policy period, no insured listed
    . . . and no "employee" authorized by you to give or
    receive notice of an "occurrence" or claim, knew that
    the "bodily injury" or "property damage" had occurred,
    in whole or in part.     If such a listed insured or
    authorized "employee" knew, prior to the policy
    period, that the "bodily injury" or "property damage"
    occurred, then any continuation, change or resumption
    of such "bodily injury" or "property damage" during
    or after the policy period will be deemed to have been
    known prior to the policy period.
    On February 12, 2009, Denise Doherty ("Doherty"), a
    resident in a Lundgren-managed building, filed a complaint in the
    Superior Court for Suffolk County, Massachusetts, against the
    Admirals Flagship Condominium Trust ("Admirals"), certain named
    trustees of Admirals, Lundgren, and Construction by Design, LTD
    ("CBD").      In the complaint, Doherty asserted negligence claims
    against Lundgren stemming from alleged water infiltration into her
    condominium.       On   April   29,   2009,       Doherty   filed   an   amended
    complaint that proffered new factual information and asserted
    additional claims of misrepresentation, nuisance, trespass, and
    breach   of    contract   under   Massachusetts       law   ("the   Underlying
    Complaint").
    -3-
    According to the Underlying Complaint, in February 2002,
    Doherty purchased a condominium unit in a building owned by
    Admirals.     Admirals contracted with Lundgren to serve as the
    property manager of the building.      In turn, Lundgren contracted
    CBD to maintain and repair the building.    "During the year 2004[,]
    leaks developed in the roof above [Doherty's] unit and/or the
    exterior area of the structure just below the roof line."   Doherty
    alleged that subsequent repairs to the ceiling were "not made in
    a timely or appropriate manner."       In 2005, a Lundgren employee
    notified Doherty that the threshold leading to her condominium's
    deck was rotting.   In February 2006, Doherty discovered a mushroom
    and water infiltration on "said threshold" and notified Lundgren.
    At that time, Lundgren asked CBD to replace the rotting threshold.
    According to Doherty, CBD "did not do this repair in a timely
    manner and left the debris exposed in [her] bedroom."
    On March 10, 2006, Gordon Mycology Laboratory, Inc.,
    hired by Lundgren to conduct mold testing, "issued a report
    disclosing the presence of hazardous mold in unsafe levels in
    [Doherty's] unit caused by water intrusions and chronic dampness."
    Doherty complained that although Lundgren had assured her that the
    mold problem would be resolved, the cleanup was "ineffectual."
    According to Doherty, "Lundgren . . . promised [her] that [CBD]
    would stop the leaks into the unit but it [did] not [do] so."    On
    -4-
    September 2, 2008, Doherty's doctor ordered her to leave the
    condominium and not to return unless the mold was eliminated and
    the leaks were repaired.
    Doherty alleged that she suffered damages as a result of
    the defendants' actions, including adverse health effects, loss of
    personal belongings, loss of her home, loss of value to her
    condominium unit, and loss of income.
    On June 30, 2009, shortly after the Underlying Complaint
    was   filed,    Lundgren   tendered     the   defense     of   the   Underlying
    Complaint to Philadelphia.            In a letter dated July 24, 2009,
    Philadelphia denied coverage.            It stated that "there are no
    allegations in the complaint that occurred within our policy
    period."   In addition, it stated that the "damages sought in this
    matter pertain to exposure to mold," yet, "the policy specifically
    excludes 'property damage' . . . and any damages that result from
    'fungi'    as   defined    in   the    policy"   1   (hereinafter    the   "mold
    exclusion").     Clarendon, on the other hand, financed the defense
    of Lundgren with a Reservation of Rights to exclude mold and fungus
    damage.
    1  The policy defined "fungi" as "any type or form of fungus,
    including mold or mildew and any mycotoxins, spores, scents or
    byproducts produced or released by fungi."
    -5-
    On    October     7,       2014,    North    American       Risk   Services,
    Clarendon's        third-party       claims       administrator,         demanded     that
    Philadelphia contribute to the cost of defending Lundgren.                          After
    the Doherty case eventually settled, Philadelphia again denied
    Clarendon's claim for contribution in a letter dated November 3,
    2014, admitting that "potentially" the mold exclusion did not apply
    to the allegations in the Underlying Complaint, but insisting that
    "the   alleged       damage       occurred        prior    to      the    inception     of
    [Philadelphia]'s policy, . . . during the Clarendon policy period."
    On or about March 17, 2015, Clarendon received an assignment from
    Lundgren of all the claims arising from the Doherty matter.
    B.   Procedural Background
    On    November       29,    2017,    Clarendon     filed      suit   against
    Philadelphia        in   the       Superior       Court      for     Suffolk      County,
    Massachusetts, based upon Philadelphia's denial of coverage to
    Lundgren.          Clarendon        brought       three    claims:       "Contribution"
    (Count I),        "Breach    of     Contract"       (Count      II),     and    "93A/176D
    Violations" (Count III).            In essence, Clarendon's complaint stated
    that Philadelphia breached its contract with Lundgren when it
    "improperly denied coverage for defense and indemnity," failed to
    contribute "its pro rata share for either coverage," and "failed
    to investigate the matter."                On December 21, 2017, Philadelphia
    removed the case to the United States District Court for the
    -6-
    District of Massachusetts.
    The parties agreed to discovery in phases.         Discovery
    Phase I was for the purpose of collecting information related to
    Philadelphia's duty to defend Lundgren, and later phases were
    scheduled for remaining issues in the case.            On May 21, 2018,
    Philadelphia    served   its   Rule   26(a)(1)   initial   disclosures   on
    Clarendon.     Clarendon did not provide its initial disclosures and
    did not conduct any discovery.         Philadelphia then filed a motion
    for summary judgment on July 2, 2018, which Clarendon opposed.           On
    January 8, 2019, the district court granted summary judgment for
    Philadelphia on all claims.       Clarendon Nat'l Ins. Co. v. Phila.
    Indem. Ins. Co., No. 17-12541, 
    2019 WL 134614
    , at *4 (D. Mass.
    Jan. 8, 2019).     Regarding the breach of contract claim -- which
    was premised on the allegations that Philadelphia breached its
    contract with Lundgren when it "improperly denied coverage for
    defense and indemnity" -- the court noted that Philadelphia's
    policy only covered damages caused by "bodily injury" or "property
    damage" that occurred during the policy period, and that did not
    result from the "continuation, change or resumption" of "bodily
    injury" or "property damage" "deemed to have been known prior to
    the policy period."
    Id. at *3
    (citation omitted).         The court
    further noted that the Underlying Complaint alleged damages that
    began in 2004, "well before the beginning of Philadelphia's policy
    -7-
    period on September 1, 2007," and continued throughout the years.
    Id. Accordingly, the
    court concluded that the damages were not
    covered by Philadelphia's policy.
    Id. The court
    also rejected Clarendon's contention that the
    Underlying Complaint could be read to suggest that the original
    leaks arising prior to the policy period were adequately repaired
    and "new leaks" had arisen during the period of Philadelphia's
    policy, reasoning that the Underlying Complaint clearly states
    that "the leaks and resulting problems were continuous throughout
    the relevant period," and "Philadelphia's policy also excludes
    coverage for damage that resumes during the policy period if the
    damage began and was known before the period."
    Id. Furthermore, the
    court noted that the Underlying Complaint "does not allege
    that Lundgren's repair efforts were ever successful at abating the
    leaks entirely, [or] even temporarily, such that leaks occurring
    during the policy period could have been considered new leaks."
    Id. The court
    concluded that, because the Underlying Complaint
    did   not   contain   allegations   "'reasonably   susceptible   of   an
    interpretation that they state' a claim covered by Philadelphia's
    policy," Philadelphia did not have a duty to defend or indemnify
    its insured and, thus, Clarendon's breach of contract claim failed.
    Id. at *4
    (quoting Cont'l Cas. Co. v. Gilbane Bldg. Co., 
    461 N.E.2d 209
    , 212 (Mass. 1984)).
    -8-
    Finally, the court held that Clarendon's additional
    claims for contribution and under Massachusetts General Laws,
    chapters 93A and 176D also failed because they were premised on
    the incorrect notion that Philadelphia had breached its duty to
    defend    and    indemnify     Lundgren         in   the   Doherty     case.
    Id. Accordingly, the
      court     entered        summary    judgment    dismissing
    Clarendon's complaint.
    Id. On January
         17,         2019,       Clarendon      moved    for
    reconsideration, which the district court denied on January 24,
    2019.    Clarendon Nat'l Ins. Co. v. Phila. Indem. Ins. Co., No. 17-
    12541,    
    2019 WL 319993
    ,       at    *2    (D.    Mass.   Jan. 24, 2019).
    Thereafter, on February 25, 2019, Clarendon filed a timely notice
    of appeal.2
    II.    Discussion
    We review a district court's grant of summary judgment
    de novo, construing the record in the light most favorable to the
    nonmovant and resolving all reasonable inferences in that party's
    favor. Ocasio-Hernández v. Fortuño-Burset, 
    777 F.3d 1
    , 4 (1st Cir.
    2  Although Clarendon's notice of appeal included the court's
    ruling on its Motion for Reconsideration, Clarendon failed to
    meaningfully discuss that ruling in its appellate briefs.       As
    such, any arguments regarding the court's ruling on its Motion for
    Reconsideration are waived. United States v. Zannino, 
    895 F.2d 1

    manner, unaccompanied by some effort at developed argumentation,
    are deemed waived.").

    904 F.2d 112
    , 115 (1st Cir. 1990)).
    Summary judgment may be granted only when "there is no genuine
    dispute as to any material fact and the movant is entitled to
    judgment as a matter of law."    Ameen v. Amphenol Printed Circuits,

    710 F.3d 16
    , 19 (1st Cir. 2013)).         The party opposing
    summary judgment "bears 'the burden of producing specific facts
    sufficient to deflect the swing of the summary judgment scythe.'"

    335 F.3d 15
    , 19 (1st
    Cir. 2003)).     "For this purpose, [it] cannot rely on 'conclusory
    allegations, improbable inferences, acrimonious invective, or rank
    speculation.'"
    Id. (quoting Ahern
    v. Shinseki, 
    629 F.3d 49
    , 54
    (1st Cir. 2010)).
    A.   Duty to Defend
    On appeal, Clarendon argues that the district court
    erred in its interpretation of Massachusetts law and its dismissal
    of Clarendon's breach of contract claim, which Clarendon contends
    was premised on the alleged breach of Philadelphia's duty to defend
    Lundgren.   Specifically, citing Metropolitan Property and Casualty
    Insurance   Company   v.   Morrison,   
    951 N.E.2d 662
      (Mass.   2011)
    ("Metropolitan"), Clarendon posits that under Massachusetts law,
    -10-
    "there is no requirement that the facts alleged in the complaint
    specifically       and       unequivocally         make   out    a   claim    within      the
    coverage."
    Id. at 667
    (quoting Billings v. Commerce Ins. Co.,
    
    936 N.E.2d 408
    ,      414    (Mass.       2010)).       Instead,      according        to
    Clarendon, a duty to defend should be found unless "the express
    language in the complaint unequivocally demonstrate[s] that the
    insurer does not owe coverage."                 And, here, its argument goes, the
    Underlying Complaint's generalized allegations "can be read to
    infer coverage," thus triggering Philadelphia's duty to defend
    Lundgren in the suit.
    In    support       of     the    contention        that   the   Underlying
    Complaint is reasonably susceptible to an interpretation entailing
    coverage, Clarendon argues that the Underlying Complaint specifies
    the date for only one leak: a "leak near a roofline," which
    occurred "in 2004."              It emphasizes that there is no "specific
    information as to the time and the location of other leaks," and
    that the Underlying Complaint fails to provide information about
    "when each leak occurred, what measures were taken to repair them,
    and   whether     any     of    the     repairs      were   effective."         Thus,      in
    Clarendon's view, the Underlying Complaint's assertion of "several
    leaks"   suggests        that     there       were   multiple        issues   over   time.
    Accordingly,       this      assertion        is   reasonably        susceptible     to   an
    interpretation          in      which     "a       new    leak       occurr[ed]      during
    -11-
    Philadelphia's policy period."    It further argues that even if the
    exact same 2004 leak resumed after CBD repaired it, "[a] reasonable
    inference is that Lundgren would anticipate the repairs to be
    corrected and would not know that they would reoccur after repairs
    were undertaken."
    In addition, Clarendon posits that Philadelphia, as an
    insurer, had an independent duty to investigate the "claim or loss"
    regardless of the language in the Underlying Complaint.   To comply
    with that duty, Clarendon asserts that Philadelphia should have
    "take[n] steps to obtain a copy of the [original] complaint" and
    should have "sp[oken] to its insured."      According to Clarendon,
    Philadelphia's failure to investigate, to file an interpleader
    action, and to draw inferences in favor of the insured, together
    warrant a "remand[] in its entirety" because each of those failures
    amounts to a breach of the duty to defend.
    Finally, Clarendon argues that Philadelphia should be
    estopped from denying coverage by relying on the "known loss"
    justification -- the policy provision establishing that damages
    occurring during the policy period are not covered if they result
    from the "continuation, change or resumption," of damages known
    prior to the policy period -- because, according to Clarendon,
    Philadelphia did not rely on those grounds to deny coverage in
    2009 when it initially considered Lundgren's claim.       Clarendon
    -12-
    posits that, because Philadelphia denied coverage in 2009 based on
    the "mold exclusion" and improperly induced reliance on this
    exclusion, Philadelphia cannot now shift its denial justification
    to an "entirely new" "known loss" justification in its 2014 letter.
    According     to     Clarendon,    Philadelphia         should   have    initially
    defended its insured and then sought a declaratory judgment on its
    lack of coverage claim.        We address each argument in turn.
    The parties agree that Massachusetts law governs.                Under
    Massachusetts law, an insurer's duty to defend "is determined based
    on the facts alleged in the complaint, and on facts known or
    readily knowable by the insurer that may aid in its interpretation
    of the allegations in the complaint."

    Co., 
    545 N.E.2d 1156
    , 1160 (Mass. 1989).               To establish an insurer's
    duty to defend and investigate allegations against an insured, a
    plaintiff     must     demonstrate      that     the    "allegations     in     [the
    underlying     complaint]         are   reasonably        susceptible      of    an
    interpretation that states or roughly sketches a claim covered by
    the policy terms."           
    Metropolitan, 951 N.E.2d at 667
    (quoting
    
    Billings, 936 N.E.2d at 414
    ).            The underlying complaint need not
    "unequivocally make out a claim within the coverage," but rather,
    "need only show, through general allegations, a possibility that
    the   liability      claim    falls     within    the     insurance     coverage,"
    -13-

    Cas. Co., 
    458 N.E.2d 338
    , 341 (Mass. App. Ct. 1983)), regardless
    of "the possibility that the underlying claim may ultimately fail,
    or that the merits of the claim are weak or frivolous."                  Holyoke
    Mut. Ins. Co. in Salem v. Vibram USA, Inc., 
    106 N.E.3d 572
    , 576
    (Mass. 2018).      Where there is uncertainty "as to whether the
    pleadings    include       or    are    reasonably       susceptible     to     an
    interpretation that they include a claim covered by the policy
    terms," the uncertainty "is resolved in favor of the insured," and
    the insurer's duty to defend will attach "until [the insurer]
    obtains a declaratory judgment of no coverage."                   Deutsche Bank
    Nat'l Ass'n v. First Am. Title Ins. Co., 
    991 N.E.2d 638
    , 642 (Mass.
    2013).
    However, where the allegations within the underlying
    complaint "lie expressly outside the policy coverage and its
    purpose,"   an   insurer    is   relieved     of   its   duty   to   defend    and
    investigate.     
    Metropolitan, 951 N.E.2d at 668
    (quoting Herbert A.
    Sullivan,   Inc.   v.   Utica    Mut.   Ins.   Co.,      
    788 N.E.2d 522
    ,   531
    (Mass. 2003)).     Additionally, "[e]ven where the allegations in the
    complaint state or roughly sketch a claim covered by" an insured's
    policy, no duty to defend and investigate arises if "there is
    'undisputed, readily knowable, and publicly available information'
    in court records that demonstrates that the insurer has no duty to
    -14-
    defend" and if "there is 'an undisputed extrinsic fact that takes
    the case outside the coverage and that will not be litigated at
    the trial of the underlying action.'"
    Id. (quoting Billings,
    936 N.E.2d at 200 n.8, 205).             Moreover, although an initial
    complaint may contain allegations which give rise to a duty to
    defend, the duty no longer exists when the complaint is amended to
    remove the triggering allegations.           See Herbert A. Sullivan, 
    Inc., 788 N.E.2d at 531
    .
    A close read of the Underlying Complaint and the record
    shows that the district court did not err by granting summary
    judgment for Philadelphia on the duty to defend issue.               Examined
    according to Massachusetts law, the allegations in the Underlying
    Complaint are not "reasonably susceptible of an interpretation
    that states or roughly sketches a claim covered" by Philadelphia's

      (quoting   
    Billings, 936 N.E.2d at 414
    ). The parties do not dispute that Philadelphia's
    policy expressly excludes coverage for property damage known prior
    to Philadelphia's period of coverage.               To establish that the
    Underlying Complaint "roughly sketches" a potentially covered
    event,    Clarendon   points    to   small    differences    in   grammatical
    structure between paragraphs and ambiguities arising from missing
    information about the time and place of various leaks.                Neither
    of these assertions give rise to a rough sketch of a covered claim.
    -15-
    Clarendon's reliance on the use of the word "leak" (in
    singular) in paragraph seventeen of the Underlying Complaint to
    suggest that the use of the term "leaks" in other paragraphs3 could
    reasonably      be   interpreted    as   referencing   new    distinct   leaks
    arising from different structural problems is inconsistent with a
    reading of the Underlying Complaint as a whole.             Paragraph sixteen
    of the Underlying Complaint clearly states that "[d]uring the year
    2004 leaks developed in the roof above [Doherty's] unit and/or the
    exterior    area     of   the   structure    just   below   the   roof   line."
    (Emphasis added). The Underlying Complaint then goes on to discuss
    the water infiltration problems caused by these "leaks" that
    started in 2004, including the fact that "[t]he roof leak caused
    ceiling cracks and loosening plaster in [Doherty's] unit," as
    stated     in   paragraph       seventeen.      Contrary     to   Clarendon's
    contentions, the fact that the Underlying Complaint does not
    mention the precise location, time, and repairs undertaken is
    insufficient to show that Doherty's claim "possib[ly] . . . falls
    within the insurance coverage."          See 
    Billings, 936 N.E.2d at 414
    .
    The Underlying Complaint unambiguously indicates that the 2004
    repairs were not made in an "appropriate manner," and that Doherty
    had continued to request "complete repair of all leaks . . . to no
    3  See Underlying Complaint at ¶¶ 16, 24, 26, and 27 ("leaks"); 17
    ("leak"); 28 ("all leaks").
    -16-
    avail."    See Underlying Complaint at ¶¶ 17 and 28.           Further, it
    references "chronic dampness" occurring at least as early as
    March 10, 2006, before the inception of Philadelphia's policy.
    See Underlying Complaint at ¶¶ 23 and 28. Nothing in the Underlying
    Complaint is reasonably susceptible to an interpretation in which
    the leaks were resolved prior to the inception of Philadelphia's
    policy.     Clarendon,    therefore,   has    failed   to   show   that   the
    Underlying Complaint provides the "rough sketch" of a covered event
    necessary to trigger the duty to defend.        
    Metropolitan, 951 N.E.2d at 667
    .4
    Furthermore,     contrary     to   Clarendon's     contentions,
    Philadelphia did not have an independent duty to investigate claims
    4  Although its arguments are not a model of clarity, Clarendon
    also seems to suggest that Lundgren could rely on CBD to resolve
    the leaks, negating its knowledge of a problem, and thus each
    resumption would be a "new leak" or new "property damage" under
    the policy. This argument, however, is not consistent with the
    plain terms of the insurance policy, which provides in relevant
    part: "If such a listed insured or authorized 'employee' knew prior
    to the policy period, that the 'bodily injury' or 'property damage'
    occurred, then any continuation, change or resumption of such
    'bodily injury' or 'property damage' during or after the policy
    period will be deemed to have been known prior to the policy
    period."    There is no dispute that the Underlying Complaint
    alleges that Lundgren initially knew about the property damage and
    made representations about their repair. See Underlying Complaint
    at ¶¶ 18, 24. Regardless of its reliance on CBD to effectuate
    repairs and whether Lundgren knew or reasonably believed them to
    be effective, under the plain terms of the policy, the damages
    would be a "resumption of such 'property damage'" of which Lundgren
    was initially aware.
    -17-
    that were not reasonably susceptible of an interpretation that
    states or roughly sketches a claim covered by its policy.                    See
    id. at 667-68
    ("[W]hen the allegations in the underlying complaint
    'lie expressly outside the policy coverage and its purpose, the
    insurer   is   relieved     of    the    duty    to   investigate.'"        (quoting
    
    Billings, 936 N.E.2d at 414
    )); see also Nascimento v. Preferred
    Mut. Ins. Co., 
    513 F.3d 273
    , 277 (1st Cir. 2008).                   While Clarendon
    is correct that Massachusetts law does look to facts "known or
    readily knowable by the insurer" as well as to the underlying
    complaint to determine whether a duty to defend has been triggered,
    information that is "readily knowable" is distinct from the duty
    to investigate.        
    Metropolitan, 951 N.E.2d at 667
    -68 (quoting
    
    Billings, 936 N.E.2d at 414
    , 417).                 This Court has held that
    information    known   or   readily      knowable        does   not   independently
    trigger the duty to defend under Massachusetts law when the
    complaint does not "adumbrate a claim."                   Open Software Found.,
    Inc. v. U.S. Fidelity & Guar. Co., 
    307 F.3d 11
    , 15-16 (1st Cir.
    2001) (internal quotation marks omitted) ("Massachusetts courts
    generally use extrinsic facts . . . to aid interpretation of the
    complaint, and not as independent factual predicates for a duty to
    defend. . . .    We do not consider them as independent grounds for
    a duty to defend."); accord Bos. 
    Symphony, 545 N.E.2d at 1160-61
    .
    Philadelphia    therefore        did    not     breach     either     its   duty   to
    -18-
    investigate or its duty to defend Lundgren.
    Finally, we refuse to address, on waiver grounds, the
    merits of Clarendon's argument that Philadelphia is estopped from
    relying on the "known loss" justification to deny coverage because,
    according       to   Clarendon,       Philadelphia        changed    its   grounds    for
    denial     of    coverage      between     2009     and    2014.     Contrary   to    its
    contentions, Clarendon did not properly raise that claim in the
    district court.             While Clarendon may have flagged discrepancies
    between     the      2009    and    2014   denial-of-coverage         letters   in    the
    district court, it never affirmatively linked these discrepancies
    to    an   estoppel     argument       nor    explained      how    they   resulted    in
    Lundgren's reliance.               A litigant's mere mentioning of facts that
    could potentially make up a claim is insufficient to effectively
    raise the argument.                United States v. Slade, 
    980 F.2d 27
    , 30
    (1st Cir. 1992) ("Passing allusions are not adequate to preserve
    an argument in either a trial or appellate venue.").
    B. Claims for contribution and for alleged                             violations      of
    Massachusetts General Laws, chapters 93A and 176D
    Next, Clarendon challenges the district court's entry of
    summary judgment dismissing its contribution claim (Count I) and
    its claim for alleged violations of Massachusetts General Laws,
    chapters 93A and 176D (Count III).5                       Despite mentioning in its
    5    Clarendon interchangeably refers to "consumer protection claim"
    -19-
    opening brief's statement of the case that it was seeking appellate
    review of the dismissal of its contribution claim, Clarendon did
    not discuss this elsewhere in its briefs.             We thus deem the
    contribution claim waived.     See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990).     Even if not waived, Clarendon's challenge
    to the summary dismissal of its contribution claim would fail
    inasmuch   as   it   was   premised   on   the   incorrect   notion   that
    Philadelphia had breached its duty to defend and to indemnify
    Lundgren in the Doherty case and thus needed to proportionately
    contribute to Clarendon, who had satisfied an obligation common to
    both Clarendon and Philadelphia.      See Ins. Co. of the State of Pa.
    v. Great N. Ins. Co., 
    45 N.E.3d 1283
    , 1286 (Mass. 2016) ("Under
    the doctrine of equitable contribution, where multiple insurers
    provide coverage for a loss of an insured, an insurer who pays
    more than its share of the costs of defense and indemnity may
    require a proportionate contribution from the other coinsurers.").
    We now turn to the remaining claim.          Clarendon first
    argues that the district court improperly dismissed its claim for
    alleged violations of Massachusetts General Laws, chapters 93A and
    176D because "Philadelphia's Motion for Summary Judgment did not
    seek dismissal of [that] claim" and, thus, "Clarendon was not
    and "bad faith claim" to describe Count III.
    -20-
    afforded an opportunity to oppose [its] dismissal."                  In addition,
    Clarendon     claims   that   if   Philadelphia           had    conducted     an
    investigation, "it would have learned that Lundgren did not 'know'
    of an ongoing loss at the time [that] the [Underlying] Complaint
    was filed because CBD had undertaken repairs and abated several
    issues."     It asserts that the Underlying Complaint "includes
    allegations of personal property damage caused by water alone,
    which would not result in the personal property damage being
    excluded by the mold exclusion."              It maintains that both the
    failure to investigate and the 2009 denial on the basis of the
    mold exclusion constitute bad faith that survives regardless of
    whether Philadelphia had a duty to defend.          We address Clarendon's
    procedural and substantive challenges in turn.
    Contrary to Clarendon's contentions, in its motion for
    summary    judgment,   Philadelphia     did     request    the   dismissal    of
    Clarendon's claim for alleged violations of Massachusetts General
    Laws, chapters 93A and 176D.6      Specifically, it stated:
    "Phase 1" is intended to focus on the duty to defend
    issue. However, because [Philadelphia] had no duty
    to defend the insureds in the underlying Suffolk
    Superior Court action, Clarendon's claims against
    [Philadelphia] in the other two counts (for equitable
    contribution and alleged violations of Chapter
    93A/176D) fail as a matter of law, and should also be
    dismissed.
    6   So did Philadelphia       request     the    dismissal      of    Clarendon's
    contribution claim.
    -21-
    Philadelphia also briefed the issue in its memorandum of law in
    support of summary judgment.           There, Philadelphia stated that if
    the district court were to grant summary judgment as to the duty
    to defend issue, then:
    [A]s a matter of law Clarendon cannot prove that it
    is entitled to "contribution" as alleged in Count I,
    or that [Philadelphia] violated M.G.L. ch. 93A or 176D
    [ ] as alleged in the third count . . . of Clarendon's
    Complaint. The Court should therefore grant summary
    judgment and dismiss the Plaintiff's Complaint in its
    entirety.
    Philadelphia then proceeded to discuss why those two claims failed
    as a matter of law.           The issue was thus squarely before the
    district court, and Clarendon had the opportunity to address it.
    In fact, Clarendon did address Philadelphia's arguments in its
    opposition to summary judgment, including the merits of its claim
    for alleged violations of chapters 93A and 176D.7                    Accordingly,
    Clarendon's      contention    that     the     district    court    abused       its
    discretion in dismissing Count III without giving it an opportunity
    to oppose such dismissal lacks merit.
    We   now   turn    to     Clarendon's     substantive        challenge.
    Massachusetts     General     Laws    chapter    176D,   section     2    prohibits
    insurance   providers       from     engaging    in   "an   unfair       method    of
    7  Clarendon also addressed the merits of its contribution claim,
    stating that "[t]he contribution claim [Count I] survives the
    Motion because the defense is based upon Philadelphia's [duty to
    defend] argument succeeding, and that argument fails."

    policy    terms   may    constitute    bad   faith,   "plausible,   although

    Clarendon's claim is premised on Philadelphia's alleged
    failure to investigate the allegations in the Underlying Complaint
    and to adequately inform its insured of the basis for the denial.

    failed to adequately inform its insured of the basis for its denial
    of coverage.     We note that in its 2009 letter, Philadelphia
    grounded its denial not only on the mold exclusion, but also on
    the fact that the allegations included in the Underlying Complaint
    had occurred outside of the coverage period.              It advised that
    "there are no allegations in the complaint that occurred within
    our policy period." That, by itself, dooms Clarendon's contentions
    that Philadelphia violated Mass. Gen. Laws chs. 93A and 176D.            See
