¶ 1 Radiator Specialty Company (RSC) is a North Carolina-based manufacturer of automotive,
hardware, and plumbing products, including cleaners, degreasers, and lubricants. Some of the
products RSC has manufactured contained benzene. Over the past twenty years, RSC has been named in
hundreds of personal injury lawsuits seeking damages for bodily injury allegedly caused by repeated
exposure to benzene over time. During that same period, RSC purchased more than one-hundred
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
standard-form product liability policies from twenty-five insurers, including the three insurers
remaining in this action: Fireman’s Fund Insurance Company (Fireman’s Fund), Landmark American
Insurance Company (Landmark), and National Union Fire Insurance Company of Pittsburgh, PA (National
Union) [collectively, the insurers]. RSC now seeks compensation from those insurers for liabilities
it has incurred as a result of its benzene litigation.
¶ 2 This case presents a challenge that is unique from personal injury cases in which the
injury occurs at a definite time and place. Unlike a car crash, for example, where the injury takes
place on a clearly discernable date, benzene exposure may take place over the course of several
years, spanning multiple insurance-policy periods and implicating different providers. More
complicated still, the consequences of that exposure may not become apparent for even longer. As a
result, as the courts of New York have stated,
[c]ourts across the country have grappled with so-called “long-tail” claims—such as those seeking
to recover for personal injuries due to toxic exposure and property damage resulting from
gradual or continuing environmental contaminations—in the insurance context. These types of
claims present unique complications because they often involve exposure to an injury-inducing
harm over the course of multiple policy periods, spawning litigation over which policies are
triggered in the first instance, how liability should be allocated among triggered policies and the
respective insurers, and at what point insureds may turn to excess insurance for coverage.
In re Viking Pump, Inc., 27 N.Y.3d 244, 255 (2016).
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
¶ 3 This dispute concerns which insurers are obligated to pay which costs arising from RSC’s
benzene liabilities pursuant to the terms of the insurers’ liability insurance policies. To answer
this question, we must decide as a matter of law (1) when each insurer’s coverage is triggered in
these circumstances—that is, whether coverage is triggered when a claimant is exposed to benzene,
or instead, when the claimant develops observable bodily injury, such as sickness or disease
(exposure vs. injury-in-fact); (2) how defense and indemnification costs are allocated among
insurers when multiple policies in multiple years are triggered by the same claim (all sums vs. pro
rata); and (3) what underlying limits RSC must exhaust before seeking defense coverage from
umbrella or excess policies (vertical vs. horizontal exhaustion).
I. Background
A. Factual Background
¶ 4 For over forty years, RSC produced and sold benzene-containing products, including a
penetrating oil called Liquid Wrench. In the early 2000s, RSC became the subject of hundreds of
personal injury lawsuits arising from its use of benzene in its products. Claimants sought damages
for consequences they have suffered as a result of benzene exposure, including cancer and death.
Their claims represent what are known as long-tail claims: allegations of injury spanning over the
course of years. In other words, many of the claimants assert that they were exposed to RSC’s
benzene- containing products for years or decades, eventually developing progressive diseases.
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
As a result of this litigation, RSC has faced approximately $45 million in defense and settlement
costs. RSC has sought to have some of those costs covered by a multitude of insurance policies it
purchased over several decades from different providers. Fireman’s Fund, Landmark, and National
Union are the only such insurers that are parties to this appeal.
¶ 5 From 1971 to 2014, RSC purchased over one-hundred standard-form product liability
policies from more than a dozen insurers. Most of these policies provided coverage for one year. In
2013, RSC brought suit against its insurance providers seeking coverage for the damages it has paid
out of pocket related to its benzene litigation. Though RSC argues that the trial court erroneously
“awarded [it] only a tiny fraction of the insurance for which RSC paid more than $7.1 million in
premiums,” the insurers reject the notion that RSC has not been awarded the amount it is due under
the policies they issued, including because “[RSC] settled with certain insurers, purchased
policies with high per claim self-insured retentions or deductibles, lost some policies it
bought, or bought no applicable coverage at all.” To cover for those “gaps in its insurance
program,” the insurers argue that RSC now seeks to hold them responsible for liabilities they were
never obligated to cover.
B. Procedural History
¶ 6 On 6 February 2013, RSC filed a declaratory judgment action pursuant to
N.C.G.S. § 1-253 et seq. seeking a declaration of the duties and obligations of fifteen
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
different defendant-insurers under policies they sold to RSC between 1971 and 2012.
¶ 7 An amended complaint filed with leave of the trial court on 5 July 2015 named nine of
the original defendant insurance companies or successors in interest to the insurance companies
that sold RSC primary and excess liability policies for the same period. The amended complaint
raised additional claims for bad faith refusal to settle or pay and unfair or deceptive trade
practices against National Union. Shortly thereafter, defendants filed both answers and motions for
summary judgment on various issues of insurance contract interpretation.
¶ 8 On 28 and 29 January 2016, Judge W. David Lee issued orders addressing the issues raised
in the summary judgment motions. In its Order on Trigger of Coverage, the trial court determined
that “the exposure trigger is appropriate in the context of long tail bodily injury claims,”
meaning that “[t]he beginning of the triggered policy period is the date on which the claimant was
first exposed to benzene” and “[t]he end of the triggered policy period is the date on which the
claimant was last exposed to benzene.”
¶ 9 In its Order Regarding Allocation, the trial court determined that “pro rata allocation
applies to both defense and indemnity payments based on each insurer’s ‘time on the risk’ over the
RSC coverage block,” rejecting the “all sums” approach and making RSC “responsible for its pro rata
share of defense and indemnity costs where there has been settled, insolvent or lost policies, as
well as periods where RSC was
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
uninsured, underinsured or self-insured.”
¶ 10 In its Order on Landmark’s Motion for Summary Judgment [Order on Exhaustion], the trial
court determined that vertical exhaustion applies to the duty to indemnify under Landmark’s
umbrella policy but horizontal exhaustion applies to Landmark’s duty to defend.
¶ 11 After issuing the summary judgment orders, the case proceeded to a bench trial in June
2018 for determination of the date of exposure for any claimants for whom the exposure date was
disputed.
¶ 12 After a bench trial, the trial court entered an order of final judgment, determining
that the insurers were obligated to defend and indemnify RSC under their policies “subject to their
respective policy limits and the following rulings of this [c]ourt,” including the “Order Regarding
Allocation.” The court incorporated by reference a Sealed Order for Declaratory Relief entered on
22 February 2019 assigning past defense and indemnity costs to the insurers by applying pro rata
allocation. As a result, the insurers were required to reimburse $1.8 million of RSC’s past costs.
¶ 13 In an unpublished opinion, a unanimous panel of the Court of Appeals affirmed the
judgment of the trial court and dismissed in part. Radiator Specialty Co. v. Arrowood Indem. Co.,
No. COA19-507, 2020 WL 7039144 (N.C. Ct. App. Dec. 1, 2020).
¶ 14 First, the Court of Appeals held that the trial court appropriately applied an
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
exposure theory for when coverage was triggered as opposed to an injury-in-fact theory. Radiator
Specialty Co., 2020 WL 7039144, at *3. According to the court, it was undisputed that
the policies issued by defendants were standard-form policies with materially identical language on
the issue of when coverage triggers. These policies provided that the insurer would pay “all sums
which the insured shall become legally obligated to pay as damages because of bodily injury . . .
caused by an occurrence[.]” The policies generally define “bodily injury” as injury, sickness, or
disease sustained by a person, and “occurrence” as an accident including exposure.
Id. (alterations in original). The court rejected RSC’s argument that this Court’s decision in
Gaston County Dyeing Machine Co. v. Northfield Insurance Co., 351 N.C. 293 (2000), established that
an injury-in-fact trigger applied to all standard-form policies. Radiator Specialty Co., 2020 WL
7039144, at *3. Instead, the court noted that application of an injury-in-fact trigger in Gaston, a
case involving property damage caused by a ruptured pressure vessel, “was premised upon the notion
that a court could determine that ‘an injury-in-fact occurs on a date certain and all subsequent
damages flow from the single event.’ ” Id. (quoting Gaston, 351 N.C. at 304). By contrast, the
court took “judicial notice of the innumerable cases concerning asbestos and benzene exposure and
recognize[d] how difficult it is to ascribe a ‘date certain’ or ‘single event’ to such harm.” Id.
Accordingly, the court concluded that because “[i]njury resulting from benzene or asbestos exposure
is neither discrete nor
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
so certain . . . [r]eading the contract language and interpreting it by its terms, it seems clear
that a ‘bodily injury’ is something caused by an ‘occurrence,’ which can include exposure,” and
thus that “the trial court did not err in applying an exposure theory of coverage instead of
injury-in-fact.” Radiator Specialty Co., 2020 WL 7039144, at *4 (citing Imperial Cas. & Indem. Co.
v. Radiator Specialty Co., 862 F. Supp. 1437 (E.D.N.C. 1994), aff’d, 67 F.3d 534 (4th Cir. 1995)).
¶ 15 Second, the Court of Appeals held that the trial court “erred in applying pro rata
allocation of liability instead of an ‘all sums’ allocation” in its intermediate Order Regarding
Allocation but concluded that “this error was rendered moot by the entry of the final judgment.”
Id. According to the court,
[t]he policies, by their language, are clear—any claims covered by a particular policy must be
defended and indemnified by the insurer under that policy. By prorating plaintiff’s costs and
damages based upon “time on the risk,” the trial court reallocated those damages, potentially
imposing more costs on one party, and removing them from another, who might be differently
obligated. We recognize that these policies represent multiple years of coverage, but judicial
expediency is no excuse. We hold that it was indeed error to prorate these costs where the
contracts explicitly imposed those obligations otherwise.
Id. The court concluded, however, that the trial court’s error was corrected by the trial court’s
final judgment which “assigned costs—both in terms of defense and indemnification—to specific
parties based upon their contractual obligations.” Radiator Specialty Co., 2020 WL 7039144, at *5.
In the court’s view, by entering a
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
judgment requiring each insurer to “defend and indemnify plaintiff on the . . . claims
. . . ‘subject to its respective policy limits,’ ” the trial court “specifie[d] that the allocation
is not pro rata, but is instead subject to the contractual limitations established in the
policies,” which the court interpreted to require all sums allocation. Id. Therefore, although the
court “recognize[d] the error in the intermediate order,” it held that the error “was rendered moot
by entry of the final judgment.” Id.
¶ 16 Third, the Court of Appeals held that the trial court did not err in applying horizontal
exhaustion to Landmark’s duty to defend. Id. According to the court, Landmark’s insurance policy
“stated that it had the duty to defend suits when (1) the applicable limits of underlying insurance
were used up in the payment of judgments or settlements, or (2) no other valid and collectible
insurance was available.” Id. Because the policy specifically used the phrase “other insurance,”
the court agreed with Landmark that “this language suggests that the policy was only triggered when
any other policies held by plaintiff were exhausted.” Id. Therefore, the court held that “a proper
interpretation of the contract reveals that Landmark offered an excess policy, to be available when
all other policies were exhausted.” Id.
¶ 17 Finally, the Court of Appeals dismissed as moot RSC’s challenge to the trial court’s
intermediate order concluding that the defendant-insurers “were not estopped from denying coverage
of claims” because the trial court in its final judgment held that the defendant-insurers “owed
both a duty to defend and a duty to indemnify”
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
and dismissed one defendant-insurer’s challenge to a summary judgment motion addressing cessation
of coverage under its own policy. Radiator Specialty Co., 2020 WL 7039144, at *5–6.1
¶ 18 On 10 August 2021, this Court allowed RSC’s petition for discretionary review, Fireman’s
Fund’s cross-petition for discretionary review, and Landmark and National Union’s conditional
petition for discretionary review.
C. Policies in Dispute
¶ 19 National Union issued six annual policies to RSC that were effective from 27 November
1987 through 1 May 1992. Five of the policies provide primary liability coverage, and the sixth
policy provides excess coverage over the primary policy in effect from 1 May 1991 through 1 May
1992. The primary policies in effect from 27
November 1987 to 1 May 1990 state the following:
a. We will pay those sums that the insured becomes legally obligated to pay as damages because of
“bodily injury” . . . included within the “products-completed operations hazard” to which this
insurance applies. No other obligation or liability to pay sums or perform acts or services is
covered unless explicitly provided for under SUPPLEMENTARY PAYMENTS. This insurance applies only to
bodily injury . . . which occurs during the policy period. The “bodily injury” must be caused
by an “occurrence.” The “occurrence” must take place in the “coverage territory”. We will have
the right and duty to
1 After the Court of Appeals issued its decision, RSC moved for rehearing on the determination that
the allocation issue had been rendered moot by the trial court’s final judgment. The Court of
Appeals denied the motion.

2022-NCSC-134
Opinion of the Court
defend any “suit” seeking those damages . . . .
¶ 20 The primary policies in effect from 1 May 1990 to 1 May 1992 state the
following:
a. We will pay those sums that the insured becomes legally obligated to pay as damages because of
“bodily injury” . . . to which this insurance applies. We will have the right and duty to defend
any “suit” seeking those damages . . . .
* * *
No other obligation or liability to pay sums or perform acts or services is covered unless
explicitly provided for under SUPPLEMENTARY PAYMENTS.
b. This insurance applies to “bodily injury” . . . only if:
(1) The “bodily injury” is caused by an “occurrence” that takes place in the “coverage territory,”
and
(2) The “bodily injury” . . . occurs during the policy period.
The sixth policy provides excess coverage and incorporates and adopts the terms of the primary
policy from the period of 1 May 1991 to 1 May 1992. All six policies define “bodily injury” as
“bodily injury, sickness, or disease sustained by a person, including death resulting from any of
these at any time.” The policies define the term “occurrence” as “an accident, including
continuous or repeated exposure to substantially the same general harmful conditions.”
¶ 21 Fireman’s Fund issued three excess liability insurance policies to RSC that were
effective during three periods of time: from 10 December 1976 to 17 October
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
1977; from 17 October 1977 to 17 October 1978; and from 1 May 1979 to 1 May 1980. Each excess
policy incorporated language from certain underlying policies providing primary liability
insurance.

III. Analysis
A. Trigger of Coverage – Exposure vs. Injury-in-Fact
¶ 24 The parties dispute at what point each insurer’s coverage was triggered. All of the
relevant policies provide coverage for “bodily injur[ies]” caused by an “occurrence.” The
policies tend to define “bodily injury” or “personal injury” as injury, sickness, or disease
sustained by a person, and “occurrence” as an accident including exposure. The issue this Court
must decide, then, is the point at which the various benzene claimants experienced bodily injury
such that RSC’s coverage under the
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
policies was activated. Put differently, we must decide which policies apply to which claims by
determining the relevant event that activates an insurer’s coverage.
¶ 25 Landmark and National Union argue that this activating or triggering event is a
claimant’s actual exposure to benzene. Fireman’s Fund and RSC contend that the policies do not
provide coverage until there is a cognizable injury. As discussed below, we agree with the trial
court and the Court of Appeals that a claimant’s period of exposure to benzene is the appropriate
reference point in determining which policies provide coverage for a given benzene-related injury.
1. Injury-in-fact Trigger Theory
¶ 26 Fireman’s Fund’s primary argument in support of an injury-in-fact trigger is that the
terms of the policies it offered RSC “provide coverage for ‘Personal Injuries’
. . . which they define as ‘bodily injury,’ ‘sickness’ and ‘disease,’ which results ‘during the
policy period.’ ” According to Fireman’s Fund, these terms require an injury-in- fact trigger
because the policies only “afford[ ] coverage for actual injury which occurs during the policy
period.” Fireman’s Fund claims that the policies it offered RSC cannot be triggered by benzene
exposure alone because benzene exposure is not itself an injury-causing occurrence.2
¶ 27 Next, Fireman’s Fund argues that case law supports an injury-in-fact trigger.
2 Medical and scientific evidence presented at the trial was filed under seal. This opinion
therefore discusses sealed information only in general terms.
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
Fireman’s Fund points to this Court’s decision in Gaston County Dyeing Machine Co.
v. Northfield Insurance Co., which held that coverage for property damage was triggered by an
“injury-in-fact.” 351 N.C. 293, 302–03 (2000). Gaston concerned the point at which insurance
coverage for property damage caused by a ruptured pressure vessel was triggered. Id. at 295. We
explained that when “the accident that causes an injury-in-fact occurs on a date certain and all
subsequent damages flow from the single event, there is but a single occurrence; and only the
policies on the risk on the date of the injury-causing event are triggered.” Id. at 304.
¶ 28 According to Fireman’s Fund, the same logic applies here. Fireman’s Fund argues that,
even though benzene exposure is the cause of the claimants’ injuries, it is the actual injury—the
resulting cancers or other physical ailments—that allows claimants to “present claims and file
suits against [RSC] in the underlying benzene actions . . . Stated differently, the benzene
claimants each allege that [RSC] is liable to them for their cancers—not for the exposure itself.”
Although Fireman’s Fund acknowledges that “unlike the property damage in Gaston, the ‘bodily
injury’ here is not a single state confined to a narrow period of time,” Fireman’s Fund contends
that “the key question is the same. Whatever acts prompted the accident in Gaston, it was not until
the pressure vessel ruptured that damage occurred. If it hadn’t ruptured, there would not have been
any property damage.” Likewise, with respect to benzene exposure, Fireman’s Fund argues that
“[w]hatever exposures prompted the various
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
mutations, it was not until a malignancy developed that injury occurred.”
¶ 29 Fireman’s Fund further argues that the injury-in-fact approach is “widely accepted” and
recognizes that “multiple policy periods can be triggered in connection with progressive disease
claims.” In support of this assertion, Fireman’s Fund cites numerous cases applying an
injury-in-fact trigger of coverage while still allowing for the “application of a multiple
trigger[3] in the context of bodily injury coverage for the progressive disease claims at issue.”
See, e.g., Dow Chem. Co. v. Associated Indem. Corp., 724 F. Supp. 474, as supplemented, 727 F.
Supp. 1524 (E.D. Mich. 1989); Am. Home Prods. Corp. v. Lib. Mut. Ins. Co., 565 F. Supp. 1485
(S.D.N.Y. 1983), as modified, 748 F.2d 760 (2d Cir. 1984); Stonewall Ins. Co. v. Asbestos Claims
Mgmt. Corp., 73 F.3d 1178 (2d Cir. 1995). Relying on these cases, Fireman’s Fund argues that the
appropriate question in applying the injury-in-fact framework is “at which points in time are there
identifiable or actual ‘personal injuries’ . . . proven to have occurred to a reasonable degree of
medical certainty?”
¶ 30 Finally, Fireman’s Fund argues that benzene exposure causes identifiable
injuries-in-fact at various points in time from malignancy until diagnosis or death.
3 The multiple trigger approach recognizes that multiple events may trigger an insurer’s coverage
such that an insurer may be held liable from the date of the injury-causing occurrence until
manifestation of the injury. See J.H. France Refractories Co. v. Allstate Ins. Co., 534 Pa. 29
(1993). Courts that have adopted this approach in the asbestos context, for example, have
recognized that “exposure to asbestos or silica, progression of the pathology, or manifestation of
the disease” may all trigger an insurer’s liability if the insurer was on the risk at the time of
any one of these relevant events. Id. at 37.
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
Quoting Wilder v. Amatex Corp., 314 N.C. 550, 560 (1985), Fireman’s Fund argues that this Court has
already established that “[e]xposure to disease-causing agents is not itself an injury” and that
“in the context of disease claims,” the point in time when “the immune system fails and disease
occurs . . . constitutes the first injury.” Though recognizing that benzene is a cancer-causing
agent, Fireman’s Fund argues that exposure does not necessarily have such consequences, and
“[t]hus, to describe a mutation or series of mutations that has not developed into a malignancy as
‘bodily injury’ is not reasonable.” In Fireman’s Fund’s view, a cognizable injury only arises when
a malignancy develops into “an ‘evolving cancer,’ and actual impairment, injuries, sickness, and
disease” result, thereby triggering coverage.
¶ 31 RSC similarly argues that a policy’s coverage is triggered if and when a claimant
suffers bodily injury, sickness, disease, or death during the policy period. According to RSC, both
the trial court and the Court of Appeals “erred in holding that coverage is triggered only if a
claimant experienced exposure to benzene during the policy period.” Rather, RSC argues that both
Gaston and the plain language of the policies at issue compel application of the injury-in-fact
approach. However, RSC contends that “there is a factual dispute among the parties about how an
injury-in- fact trigger applies to the facts of this case.” Specifically, because an injury-in-fact
trigger has not yet been applied in this litigation, RSC urges that this Court should not be the
first to determine “during which policy periods . . . each benzene claimant’s
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
alleged injuries in fact occur[ed].” RSC contends that there is “[c]onflicting medical expert
testimony” creating factual and evidentiary disputes that the trial court did not resolve, and
which this Court cannot resolve. Accordingly, RSC asks this Court to remand the case to the trial
court to allow it “to apply an injury-in-fact trigger of coverage in the first instance.”
2. The Exposure Trigger
¶ 32 By contrast, Landmark and National Union ask this Court to hold that the policies
providing coverage for benzene exposure were triggered during the exposure period. As National
Union puts it, the lower courts “correctly held that coverage is triggered under those policies in
effect during a given claimant’s exposure to Benzene.” This means that “coverage is triggered if,
and only if, the underlying claimant was exposed to benzene during that policy’s effective dates
because a claimant only experiences ‘bodily injury’ during exposure to benzene.” Landmark and
National Union agree that both North Carolina law and medical evidence require this conclusion.
¶ 33 Central to their position is the argument that “a claimant only experiences ‘bodily
injury’ during exposure to benzene.” According to National Union, Fireman’s Fund’s argument
“requiring malignancy and/or diagnosable illness” as opposed to DNA damage “functionally reads the
term ‘bodily injury’ out of the definition of ‘bodily injury’ by equating it with ‘sickness’ or
‘disease.’ ” In addition to medical evidence
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
presented at trial, both Landmark and National Union rely on the United States District Court for
the Eastern District of North Carolina’s decision in Imperial Cas. & Indem. Co. v. Radiator
Specialty Co., 862 F. Supp. 1437 (E.D.N.C. 1994), in support of their position.
¶ 34 In that case, the court expressly rejected the manifestation trigger theory for
progressive bodily injury and applied the exposure trigger theory based on the “view that exposure
to the dangerous substance at issue during the policy period caused immediate, albeit undetectable,
physical harm which ultimately led to disease or physical impairment after the expiration of the
policy period.”4 Id. at 1442. (quoting Cont’l Ins. Cos. v. Ne. Pharm. & Chem. Co., 811 F.2d 1180,
1190 (8th Cir. 1987)). Both National Union and Landmark argue that this holding is consistent with
evidence that the actual bodily injuries caused by benzene exposure happen in the days following
exposure, whereas the consequences of the injury may take much longer to become detectable.
¶ 35 Despite its relevance, Fireman’s Fund contends that Gaston’s adoption of an
injury-in-fact trigger renders Imperial Casualty irrelevant because, although the federal court in
that case predicted that this Court would adopt an exposure theory,
4 Citing Imperial Casualty, National Union points out that “the majority of federal cases on this
issue [progressive diseases] have found coverage by adopting the ‘exposure’ or the ‘continuous
exposure,’ theory of when injury occurs.” 862 F. Supp. at 1442 (citing Cont’l Ins. Companies v. Ne.
Pharm. And Chem. Co., 811 F.2d 1180, 1190 (8th Cir. 1987).
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
this Court opted for the injury-in-fact approach in Gaston. Landmark and National Union reject this
assertion. For example, National Union responds that Gaston “differs from [Imperial Casualty and]
this case because it assessed trigger of coverage for property damage occurring on a date certain,
not claims for bodily injury caused by long-term benzene exposure.” According to National Union,
Gaston actually confirms that courts must “look[ ] to the evidence to determine when the damage
took place and not when the consequences of the damage became evident.” Likewise, Landmark takes
the position that Gaston did not adopt an injury-in-fact trigger in the bodily-injury context,
noting that Gaston considered property damage occurring on a date certain, rather than progressive
bodily injury resulting from exposure to a harmful substance.
¶ 36 Finally, National Union argues that this Court should not adopt Fireman’s Fund’s
“continuous trigger” theory that would allow coverage from “all policies in effect from the time a
claimant is exposed to benzene until diagnosis or death.” Though National Union acknowledges that
other courts have applied a continuous trigger theory in the context of asbestos claims, National
Union argues that “benzene is different than asbestos” because “[u]nlike benzene, asbestos stays in
the body permanently and may continue to cause new injuries after exposure.” By contrast, benzene
“causes injury only during the time periods in which a claimant is exposed to it and then is
flushed from the body within hours or days.” National Union notes
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
that other jurisdictions have rejected the continuous trigger theory in cases involving exposure to
“substances that cease causing injury once exposure stops” and cause illnesses that do not manifest
until years later. See, e.g., In re Silicone Implant Ins. Coverage Litig., 667 N.W.2d 405 (Minn.
2003); Hancock Lab’ys, Inc. v. Admiral Ins. Co., 777 F.2d 520 (9th Cir. 1985).
3. Analysis
¶ 37 The unambiguous language of each of the relevant policies requires the insurers to
indemnify RSC for claims raised by claimants who suffered some form of personal or bodily injury
caused by an occurrence and specifies that either the occurrence or the resulting injury must take
place during the effective period of the insurer’s policy. But, as Landmark and National Union
argue, the policies do not define personal or bodily injury to require some diagnosable sickness or
disease for coverage to be triggered. For example, the term “personal injury” as used in Fireman’s
Fund’s policies includes a “bodily injury,” such as that caused by “exposure.”
¶ 38 As Landmark and National Union argue, benzene causes bodily injury upon exposure.
Fireman’s Fund’s and RSC’s attempt to redefine “injury-in-fact” as death, disease, or some other
physical manifestation of the harm confuses the injury with its consequences. Assuming there is no
intervening cause, cancer is a manifestation of the injury that occurs upon benzene exposure that
creates a compensable claim. It is not the injury itself. Even though we hold that exposure to
benzene is synonymous
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
with the coverage-triggering injury, that injury is only compensable if it results in damages. In
other words, if a person is exposed to benzene but suffers no consequences as a result, the
individual has sustained no compensable harm.
¶ 39 We are persuaded by the reasoning of Imperial Casualty. Quoting the Sixth Circuit’s
decision in a similar asbestos exposure case, the United States District Court for the Eastern
District of North Carolina noted that “[c]umulative disease cases are different from the ordinary
accident or disease situation” in part because, if the injury-in-fact theory were adopted, “the
manufacturer’s coverage becomes illusory since the manufacturer will likely be unable to secure any
insurance coverage in later years when the disease manifests itself.” Imperial Casualty, 862 F.
Supp. at 1443 (quoting Ins. Co. of North Am. v. Forty-Eight Insulations, 633 F.2d 1212, 1219 (6th
Cir. 1980)). This makes good sense: If coverage is triggered only upon disease manifestation, then
a company that obtained coverage during a period that it manufactured products with benzene could
not invoke its coverage if the individuals who were exposed to benzene during the coverage period
did not develop a disease or die until after the policy expired. That would make the availability
of coverage to RSC predicated on its maintenance of coverage in perpetuity, even if RSC had stopped
manufacturing benzene-containing products.
¶ 40 Gaston does not overrule or otherwise displace Imperial Casualty. In Gaston, this Court
was selecting between “an ‘injury-in-fact’ or a ‘date-of-discovery’ trigger of
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
coverage . . . where the date of property damage [was] known and undisputed.” Gaston, 351 N.C. at
299. The Court of Appeals is correct that, in dealing with coverage for property damage, Gaston
involved distinct factual circumstances. But at their core, the factual distinctions between this
case and Gaston relate to how to properly define the injury, which in turn controls when coverage
is triggered under the relevant policies.
¶ 41 Gaston explicitly rejected the notion that coverage-triggering damage “occurs ‘for
insurance purposes’ at the time of manifestation or on the date of discovery.” Id. at 303
(overruling W. Am. Ins. Co. v. Tufco Flooring E., 104 N.C. App. 312 (1991)). Instead, “the accident
that causes an injury-in-fact occurs on a date certain and all subsequent damages flow from the
single event, there is but a single occurrence; and only policies on the risk on the date of the
injury-causing event are triggered.” Id. at
304. Nothing in Gaston suggests either that exposure to a substance causing alterations to a
person’s DNA is not an “injury-in-fact” or that an insurer offering coverage when a claimant is
exposed to benzene is not liable for all the damages arising from that injury.
¶ 42 Finally, Fireman’s Fund argues that, if we apply the exposure theory to this case, we
“should also hold that . . . policies in place throughout the development of a claimant’s
malignancy and the ‘evolving cancer,’ and the resulting bodily injury, sickness, and disease should
be triggered too.” According to Fireman’s Fund, “it would
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
be anomalous to hold that coverage is triggered by exposure alone, when the claimant is healthy,
but that there is no coverage triggered during the times when a claimant” is ill. This application
of a continuous trigger would be at odds with our holding that, in benzene cases, the injury that
triggers coverage occurs at the time of exposure.
¶ 43 Consistent with other courts that have decided the issue, National Union and Landmark
have established that an injury occurs at the time of benzene exposure. To apply a continuous
trigger approach in this context would be to adopt Fireman’s Fund’s and RSC’s mischaracterization
of the relevant injury: In order for the policies to provide coverage, we would be required to
label the injury’s consequences (e.g., cancer) as the bodily injury itself. Thus, under these
circumstances, a continuous trigger is necessarily inconsistent with an exposure trigger.5
B. Allocation
¶ 44 Next, the parties ask this Court to determine how to properly allocate RSC’s benzene
liabilities among the providers. As discussed, while some injuries occur at a definite time and
place, other injuries, such as those resulting from benzene exposure, are not so definite and could
have resulted from any one exposure over a period of
5 Whether the multiple-trigger theory should apply in a given case requires a fact- intensive
analysis regarding the nature of the injury in question. In the context of benzene exposure where
DNA mutations occur upon exposure, benzene is expelled from the body within a matter of days, and
the injury ceases shortly after exposure ceases, the cancer that may later result is not itself a
new injury that would trigger additional policies. But where the injury-inducing condition persists
over time, such as in the context of asbestos exposure or environmental contamination, or later
results in new, distinct injuries, the multiple- trigger theory may be appropriate.
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
years. In these circumstances, the injury may implicate numerous insurance policies provided by
different insurers over the course of the period during which the damage could have occurred. In
such cases, it is necessary to determine how to apportion costs arising during the various policy
years to the appropriate insurers.
¶ 45 The period during which a particular policy’s coverage is triggered is referred to as
“time on the risk.” Under a pro rata, or time-on-the-risk, allocation approach, “each triggered
policy bears a share of the total damages proportionate to the number of years it was on the risk,
relative to the total number of years of triggered coverage.” Thomas M. Jones & Jon D. Hurwitz, An
Introduction to Insurance Allocation Issues in Multiple-Trigger Cases, 10 Vill. Envtl. L.J. 25, 42
(1999). As Fireman’s Fund explains, “costs are allocated among the policies according to their
respective time on the risk.” By contrast, all sums, or joint and several, liability “allows
recovery in full under any triggered policy of the policyholders’ choosing and leaves the selected
insurer to pursue cross-claims against other carriers whose policies were also available.” Id. at
37. This means that “any policy on the risk for any portion of the period in which the insured
sustained property damage or bodily injury is jointly and severally obligated to respond in full,
up to its policy limits, for the loss.” Id. at 37– 38.
¶ 46 All three insurers argue that pro rata allocation is appropriate based on the terms of
their policies, whereas RSC advocates for adopting an all sums approach.
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
The trial court applied the pro rata method, but the Court of Appeals held that all sums allocation
was warranted.
1. Mootness
¶ 47 Although the Court of Appeals held that the trial court erroneously applied pro rata
allocation in its intermediate order, it further held that this error was rendered moot because the
trial court entered a final judgment “specif[ing] that the allocation is not pro rata, but is
instead subject to the contractual limitations established in the policies,” which the Court of
Appeals interpreted to require all sums allocation. Radiator Specialty Co., 2020 WL 7039144, at *5.
¶ 48 RSC contends that the Court of Appeals reached the correct ultimate substantive
conclusion—that the standard-form policy language compels an all sums rather than pro rata
allocation of costs—but “muddled its correct legal ruling by mistakenly failing to apply it to the
trial court’s Final Judgment.”
¶ 49 RSC argues that the trial court’s final judgment incorporated the intermediate Order
Regarding Allocation, which interpreted the disputed policy language to compel pro rata allocation.
When the trial court’s final judgment ordered the insurers to defend and indemnify RSC “subject to
their respective policy limits,” it meant “subject to their respective policy limits” as
interpreted by the trial court (e.g., subject to their respective policy limits under a pro rata
allocation method). RSC asks this Court to correct the Court of Appeals’ error and ensure that it
is paid in accordance
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
with the all sums allocation method the Court of Appeals held to be required by the insurance
policies.
¶ 50 The insurers do not appear to contest RSC’s assertion that the Court of Appeals erred in
holding that the trial court’s final judgment order rendered its intermediate order moot. Instead,
they ask that “[i]f this Court reverses the Court of Appeals’ mootness determination, it should
also reverse the Court of Appeals’ unsupported endorsement of all-sums allocation because all-sums
allocation is incompatible with the terms of the National Union policies, inequitable, and bad
public policy.”
¶ 51 Though RSC is correct that the Court of Appeals misconstrued the trial court’s final
judgment as calling for all sums allocation, our resolution of the substantive question—that pro
rata allocation is appropriate—overrules the Court of Appeals’ suggestion to the contrary. For the
sake of clarity, the trial court’s final judgment should be read to require costs to be assigned
pro rata.
2. Pro Rata versus All Sums Allocation
a. The insurers’ pro rata allocation position.
¶ 52 The insurers’ central argument is that the express language of the contracts
contemplates pro rata rather than all sums allocation. For example, as National Union explains, its
policies with RSC contain one of two substantively identical insuring provisions stating, in
effect, that National Union “will pay those sums that [RSC] becomes legally obligated to pay as
damages because of ‘bodily injury’ . . . . This
RADIATOR SPECIALTY CO. V. ARROWOOD INDEM. CO.
2022-NCSC-134
Opinion of the Court
insurance applies only to bodily injury . . . which occurs during the policy period.” According to
National Union, this “express and plain language require[s] pro-rata allocation, and the Court of
Appeals erred in stating otherwise.” National Union argues that all sums allocation is only
appropriate when an insurance policy specifically contemplates pay
