OPINION

MAASSEN, Justice.

I. INTRODUCTION

Fifteen-year-old Kevin Michaud fired a single shot from a revolver belonging to his parents, killing one friend and seriously wounding another. The parents of the two victims sued Kevin, his parents, and their insurance company, United Services Automobile Association (USAA). The Michauds' liability policy provided a $300,000 limit for "Each Occurrence" of "Personal Liability." The superior court ruled that the policy afforded $900,000 of coverage because there had been a single occurrence and Kevin and his parents were each entitled to a separate per-occurrence policy limit. USAA appeals, arguing that the policy affords a single per-occurrence policy limit of $300,000 regardless of the number of insureds. The victims' parents also appeal; they contend that not only were there three individual coverage limits, one each for Kevin and his parents, but there were also multiple occurrences. We conclude that USAA's position is most in accord with the express language of the policy, the reasonable expectations of an insured, and case law, and we therefore reverse the superior court's decision.

II. FACTS AND PROCEEDINGS

On December 10, 2008, Kevin Michaud was visiting with some friends in his home after school. He took a revolver from his father's gun cabinet, handled it for awhile, then put a bullet in one chamber of the cylinder. He aimed the revolver at himself and pulled the trigger, then aimed at his friend, 14-year-old Aidan Neary, and pulled the trigger again. The gun fired on the second pull of the trigger. The shot passed through Aidan's body, fatally wounding him, then struck 14-year-old Charles J. Schneider III (Chase) in the spine, where the bullet still remains.

Chase and his parents, Charles J. Schneider II and Dareen Puhlick, sued Kevin and his parents, Michael K. and Michele M. Michaud. They alleged several theories of liability, including negligence and negligent infliction of emotional distress (NIED). Aidan's estate and Aidan's parents, Mary E. and Patrick T. Neary, also sued the three Michauds on theories including negligence and NIED. The NIED claims were based on the emotional trauma the parents experienced upon witnessing the harm caused to their children. Both the Neary and the Schneider/Puhlick families also sued the Michauds' insurer, USAA, seeking a declaratory judgment as to USAA's liability under its policy. USAA counterclaimed for a declaratory judgment limiting coverage.1

For ease of reference we refer to the parents of Aidan and Chase as "the parents" and to Kevin's parents as "the Michauds."

The Declarations Page of the Michauds' insurance policy, under the heading "COVERAGES AND LIMITS OF LIABILITY," provides: "SECTION II. E. Personal Liability — Each Occurrence $300,000." The definitions section of the policy defines the word "occurrence" as meaning "an accident, including continuous or repeated exposure to substantially the same general harmful conditions, which results, during the policy period, in: a. bodily injury; or b. property damage."

Section II, Coverage E, to which the Declarations Page refers, describes more specifically the grant of coverage for "Personal Liability" and provides, in pertinent part:

Section II also contains several pages of "Conditions," two of which are relevant to our discussion here:

USAA moved for summary judgment in the superior court, arguing that it could be liable under its policy for no more than $300,000, a single per-occurrence policy limit, for all claims against its three insureds. The parents opposed the motion, arguing that there was a genuine issue of material fact as to the number of occurrences and thus as to the amount of USAA's possible liability. The Michauds opposed USAA's motion as well and cross-moved for summary judgment themselves, arguing that they were each entitled to a separate coverage limit of $300,000 and that there were multiple occurrences.

The superior court held that (1) each of the three Michauds was entitled to a separate coverage limit of $300,000 per occurrence, and (2) there was one occurrence, meaning that the available limits under the policy were $900,000. USAA appeals the first ruling, arguing that the policy's per-occurrence limit of $300,000 does not vary depending on the number of insureds. The parents appeal the second ruling, arguing that the facts of this case gave rise to multiple occurrences: the bodily injury to the two shooting victims and the emotional distress suffered by the victims' four parents. They argue in the alternative that each negligent act or omission by Kevin and his parents that led up to the shooting was a separate occurrence.

III. STANDARD OF REVIEW

"We review the grant of a summary judgment motion de novo, affirming if the record presents no genuine issue of material fact and if the movant is entitled to judgment as a matter of law."2 In making this assessment, we draw all reasonable inferences in favor of the non-moving party.3 A superior court's interpretation of insurance policy language is a matter of law reviewed de novo.4 In this case, the victims' parents and USAA all moved for summary judgment. We will make all reasonable inferences in favor of the opposing party when evaluating each party's arguments in support of summary judgment.

IV. DISCUSSION

A. The Michauds' Liability Insurance Policy Provided A Single Per-Occurrence Limit Of $300,000.

When interpreting insurance policies, we look to the language of the disputed provisions, other provisions in the policy, extrinsic evidence, and case law interpreting similar provisions.5 Insurance policies are construed in such a way as to honor the reasonable expectations of a layperson seeking coverage.6 Ambiguities will be construed most favorably to the insured.7 Policy language is ambiguous when it is susceptible to two or more reasonable interpretations.8 Absent ambiguity, we will still rule in favor of coverage if that is the only way to effectuate the insureds' objectively reasonable expectations, even though "painstaking study of the policy provisions would have negated those expectations."9

The provisions at issue here regarding the limits of the Michauds' homeowners' policy are not ambiguous. The policy's Declarations page states that the "Personal Liability" limit of $300,000 applies to "Each Occurrence." Nothing on the Declarations page suggests that this number will be increased depending on the number of insureds; indeed, such a construction is expressly prohibited by other language in the policy. Section II addresses the Michauds' "Liability Coverages." It commits USAA to "pay up to [its] limit of liability for the damages for which the insured is legally liable" for covered liability claims. (Emphasis added.) A portion of Section II labeled "Conditions" further explains what is meant by "Limit of Liability": "Our total liability under Coverage E for all damages resulting from any one occurrence will not be more than the limit of liability for Coverage E as shown in the Declarations." Adding further to the clarity, the provision then states, "This limit is the same regardless of the number of insureds, claims made or persons injured."

This unambiguous language plainly precludes the result the parents seek here: a multiplication of the limit of liability by "the number of insureds." We have found no case in which a court faced with the same policy language applied a separate per-occurrence policy limit to each insured, though courts have declined to do so. In a case involving an automobile policy, Folkman v. Quamme, the Supreme Court of Wisconsin rejected the argument that an "each occurrence" limit applied to each insured.10 It observed that the liability provision at issue was not ambiguous — the insureds "must add the words `for each insured' to the endorsement for it to acquire the meaning they offer" — and that under the insureds' analysis the insurer "could never be certain what its total liability would be," giving as an example an automobile accident in which a number of insureds in the same vehicle were arguably at fault.11

The parents argue that USAA's reading of the policy is contradicted, or at least made ambiguous, by three of the policy's provisions. First, they rely on the "Personal Liability" provision of the Liability Coverages section, arguing that the word "personal" implies that the coverage limit applies separately to each individual insured rather than to the insureds as a group. But the phrase "Personal Liability" simply describes the type of coverage that the liability section provides — for damages in tort for which an insured can be held personally liable;12 it does not purport to expand that coverage or to define its dollar limits.

Second, the parents rely on the sentence in the coverage provision that commits USAA to "pay up to [its] limit of liability for the damages for which the insured is legally liable." The parents contend that this sentence, with its use of "the insured" in the singular, again implies that the full limit of liability is available for the damages assessed against each individual insured. We find this argument unconvincing given that the commitment to "pay" in this sentence is expressly qualified by the limit of liability, plainly stated elsewhere in the policy to be a single, per-occurrence limit.

Finally, the parents argue that the policy's severability clause supports their reading. Captioned "Severability of Insurance," the clause provides: "This insurance applies separately to each insured. This condition will not increase our limit of liability for any one occurrence." (Emphasis added.) Severability clauses are generally interpreted to mean that a policy's exclusions and conditions apply separately to each insured;13 for example, the activity of one insured that brings him within a policy exclusion will not be imputed to other insureds when they seek coverage under the same policy.14 Severability clauses are not coverage provisions; they do not increase policy limits.15 The USAA policy makes this very clear by stipulating that the clause "will not increase our limit of liability for any one occurrence." The parents argue that this qualification can be read as capping each individual insured's coverage at $300,000 per occurrence regardless of the number of claims or injured persons. Such a reading, however, even if otherwise reasonable, would still require the insured to look elsewhere to determine the limit of liability, as the severability clause merely states that it "will not increase" that limit whatever it may be. As described above, the limit of liability is plainly stated in the policy to be a per-occurrence limit of $300,000 that does not vary "regardless of the number of insureds, claims made or persons injured." The severability clause, in short, cannot be read to supply a per-insured limit of liability that is not found elsewhere in the policy.

As for extrinsic evidence, the parents do not point to any that could support a finding that the Michauds, despite the plain language of their policy, reasonably expected separate, individual per-occurrence limits. We have looked in the past to such evidence as statements by the insurer's sales representatives and the insurer's printed flyers or brochures for an indication of the reasonable expectations of the insured seeking coverage.16 No such evidence exists in this case. The Michauds asserted in their pleadings below that they never discussed the relevant coverage provisions with representatives of their insurance company and never developed any relevant expectations with regard to coverage. These assertions do not appear to have been disputed. We enforce the unambiguous policy language and hold that the policy's single per-occurrence limit applied regardless of the number of insureds.

B. There Was A Single Occurrence.

The parties also disagree on the number of occurrences: USAA claims there was one because there was a single gunshot, and the parents assert that there were at least six because there were six injured victims (the two children and their four parents). The Michauds' insurance policy defines "occurrence" as "an accident, including continuous or repeated exposure to substantially the same general harmful conditions, which results ... in ... bodily injury." The policy does not define "accident," but our case law defines the term as "anything that begins to be, that happens, or that is a result which is not anticipated and is unforeseen and unexpected."17 We conclude that there was a single "accident" in this case that "result[ed] ... in ... bodily injury" and therefore a single occurrence for purposes of the limits of liability. This conclusion is consistent with our precedent interpreting similar policy language and with the reasonable expectations of an insured.

The parents present two separate theories in support of a finding of multiple occurrences. First they argue that each act of negligence that enabled Kevin to shoot his friends should be counted as a separate occurrence; this would include not only his own negligent handling of the gun but also each negligent act of his parents in failing to secure their firearms and supervise their son's activities. But under our case law it is the unforeseen event, not every act of negligence preceding it, that constitutes the accident or occurrence for purposes of insurance coverage. In Fejes v. Alaska Insurance Co., a contractor sought indemnity from his general liability insurer for damages caused by a subcontractor's negligent installation of a septic system.18 The insurer argued that there had been no "occurrence" because the negligent installation was not an accident.19 The contractor focused instead on the results, arguing that there was an "occurrence" when the septic system was destroyed.20 We found that the contractor had the better of the argument and held that the accident was the unexpected failure of the system, not the negligent installation that preceded it.21

In Makarka ex rel. Makarka v. Great American Insurance Co., a driver ran a red light and struck another car, killing three passengers and injuring two.22 The victims and their survivors sued the mechanic who had earlier worked on the driver's brakes and allegedly failed to repair them.23 The mechanic's insurer contended that there was no coverage because its policy had been cancelled before the driver ran the red light and killed the victims; the plaintiffs countered that coverage was triggered when the mechanic performed his negligent work, which was during the policy period.24

Noting that the policy at issue was an "occurrence" policy, we observed that "[s]uch policies provide coverage that is based on accidents or events that happen while the policy is in force."25 We referred approvingly to a statement of the California Court of Appeal that "the time of the occurrence of an accident within the meaning of an indemnity policy is not the time the wrongful act was committed, but the time when the complaining party was actually damaged."26 While this is sometimes referred to as a "general rule," we noted in Makarka that it is actually "a restatement of the terms of most occurrence-based liability insurance policies," which are "triggered by bodily injury or property damage for which legal damages are due."27 We concluded that "the proper moment to measure whether coverage is in force is the moment the person seeking damages was injured."28 The USAA policy at issue here, while worded somewhat differently than the policy at issue in Makarka, is also an occurrence-based policy that is triggered by injury occurring during the policy period; an "occurrence to which this coverage applies" is defined as "an accident ... which results, during the policy period, in ... bodily injury; or ... property damage." This language reflects the "general rule" noted above: that "the time of the occurrence of an accident" is not the time of the negligent act, but the time the plaintiff was actually damaged.29

In accord is an insurance treatise we have cited before for its definition of the term "accident:"30 "The word `accident' implies a misfortune with concomitant damage to a victim, and not the negligence which eventually results in that misfortune."31 The rule was applied by the Florida Supreme Court in a gunshot case with similarities to this one. In Koikos v. Travelers Insurance Co., two shooting victims sued the owner of a restaurant, Koikos, alleging a negligent failure of security.32 The gunman had fired two bullets, each one hitting a different victim.33 Although a single negligent omission was alleged on the part of the restaurant — the failure to maintain adequate security — the court ruled that there were two occurrences, one for each gunshot causing injury.34 The court explained:

Here, similarly, it was not the Michauds' alleged failure to secure their firearms, nor their alleged failure to supervise their son, that constituted the event that was "unforeseen and unexpected"36 from their standpoint as insureds; rather, it was "the shooting that gave rise to the injuries" that was "unforeseen and unexpected" and therefore, from their perspective, was the accident. The analysis is the same as it was in Koikos, though the mathematics are different. Here there may have been multiple acts of negligence, but it was a single gunshot that caused the plaintiffs' damages. The single gunshot was the one occurrence for purposes of liability coverage.

The parents argue separately that there were six occurrences because there were six discrete injuries: the single bullet struck both Chase and Aidan, which in turn caused emotional distress to all four parents. The parents urge us to adopt what is sometimes called the "effects" test, under which the number of occurrences is determined by the number of injuries caused. This test, however, is inconsistent with the plain language of the USAA policy, which, as discussed above, states that the limit of liability "as shown in the Declarations ... is the same regardless of the number of insureds, claims made or persons injured."

In any event, a majority of courts that have considered the effects test as a way to determine the number of occurrences have rejected it as unworkable for that purpose.37 Courts have correctly observed that the test renders insurers' liability both unpredictable and limitless, since any one event can cause many injuries to many people.38 A negligently caused explosion, for example, can injure one person or kill a hundred; it can damage one home or devastate a city block. The insurer attempting to underwrite the risk posed by the many potential effects of a single negligent act has no way to estimate its exposure and responsibly calculate its premiums. In Koikos, the court rejected the effects test under facts similar to those here, holding that the proper measure of occurrences was the number of gunshots, not the number of victims.39 We reject the effects test here as a basis for calculating the number of occurrences, and we therefore reject the parents' argument that this single gunshot constitutes as many as six different occurrences.

Finally, we believe that the rules we apply above conform to the reasonable expectations of an insured who is reading an occurrence-based policy like the one at issue here, in which "occurrence" is defined as an "accident" resulting in "bodily injury." We consider it unlikely that the ordinary insured who hears of an accident in the home, in the workplace, or on the highway will mentally convert that single event into some other number of accidents depending on the number of negligent acts and omissions that led up to it, or on the number of persons who were injured as a result. There was a single accident in this case — the unforeseen and unexpected firing of the single gunshot that caused all of the plaintiffs' injuries — and therefore a single occurrence for purposes of liability coverage under the USAA policy.

V. CONCLUSION

We REVERSE the superior court's summary judgment order and REMAND for proceedings consistent with this opinion.
