OPINION
This action concerns the coverage provided by a property owner’s insurance policy issued by State Farm Fire and Casualty Company to James McGowan, the former owner of an apartment building. State Farm filed a declaratory judgment action in federal court regarding its defense obligations to McGowan in a Tennessee state-court lawsuit filed by Lori L. Dutton. Dutton, who lived in one of the apartments with her four-year-old daughter Amy, filed suit against McGowan after a rotting tree collapsed onto the apartment during a thunderstorm, killing Amy. The district court held that State Farm was obligated to defend McGowan in the underlying action under the terms of the policy. For the reasons set forth below, we AFFIRM the judgment of the district court.
I. BACKGROUND
McGowan, individually and doing business as JMAC Enterprises, owned a four-unit apartment building in Red Bank, Tennessee, in which Dutton and her daughter Amy lived. The premises were insured under a policy issued by State Farm to *435 McGowan. McGowan’s insurance policy contained the following relevant provisions:
BUSINESS LIABILITY
We will pay those sums that the insured becomes legally obligated to pay as damages because of bodily injury, property damage, personal injury or advertising injury 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:
I. to bodily injury or property damage caused by an occurrence which takes place in the coverage territory during the policy period[.]
RIGHT AND DUTY TO DEFEND
We will have the right and duty to defend any claim or suit seeking damages payable under this policy even though the allegations of the suit may be groundless, false, or fraudulent. The amount we will pay for damages is limited as described in the Limits of Insurance.
DEFINITIONS
3. bodily injury means bodily injury, sickness or disease sustained by a person, including death resulting from the bodily injury, sickness, or disease at any time;
II. occurrence means:
a. an accident, including continuous or repeated exposure to substantially the same general harmful conditions which result in bodily injury or property damage[.]
(Emphases in original.)
McGowan sold the building to Mohammed Hakeem in May of 2001, but Dut-ton and Amy continued to occupy their apartment after the sale. In September of 2001, McGowan canceled his State Farm insurance policy. The cancellation was effective as of August 1, 2001.
During a thunderstorm in October of 2001, a decaying tree next to the building fell through the roof of Dutton’s apartment, killing Amy. Dutton subsequently filed a lawsuit in state court to recover damages against McGowan. Her complaint alleged that McGowan had been negligent during the time that he owned the property by failing to correct the dangerous condition created by the presence of the rotting tree, and that McGowan’s negligence caused or contributed to Amy’s death.
Upon learning of the lawsuit, McGowan demanded that State Farm defend and cover the claims against him in the state-court action. State Farm refused. It also filed a declaratory judgment action in the United States District Court for the Eastern District of Tennessee regarding its coverage and defense obligations to McGowan. State Farm subsequently filed a motion for summary judgment on the ground that the insurance policy at issue was an “occurrence” policy, and that McGowan was not entitled to coverage because the occurrence that resulted in Amy Dutton’s death did not take place during the policy period. McGowan filed a cross-motion for summary judgment, arguing that the occurrence did in fact take place during the policy period. The district court denied State Farm’s motion and granted McGowan’s, holding that State Farm had a duty under the policy to defend McGowan in the underlying lawsuit. State Farm has timely appealed.
*436 II. ANALYSIS
A. Standard of review
We review a district court’s grant of summary judgment de novo.
Minadeo v. ICI Paints,
B. The district court did not err in concluding that McGowan’s alleged negligence was an occurrence that took place during the policy period
With subject matter jurisdiction being based entirely upon diversity of citizenship, the parties do not dispute that Tennessee law applies to this case.
See Erie R.R. Co. v. Tompkins,
An insurance company’s duty to defend its insured is largely determined by the allegations in the complaint filed against the insured.
St. Paul Fire & Marine Ins. Co. v. Torpoco,
The insurance policy defines an “occurrence” as “an accident, including continuous or repeated exposure to substantially the same general harmful conditions which result in bodily injury.” As the district court noted, “[n]o party addressed the exposure-to-harmful-conditions aspect of the policy’s definition for ‘occurrence,’ so the *437 [issue is] whether the alleged negligence constitutes an accident.”
The Tennessee Supreme Court addressed the meaning of the term “accident” as used in an insurance policy in
Gassaway v. Travelers Insurance Co.,
The
Gassaway
court cited a number of cases in which an insured’s negligence qualified as an accident under policies containing similar language. Among the cases cited were
American Employers Insurance Co. v. Knox-Tenn Equipment Co.,
The court in
Gassaway
distinguished the above cases from the one before it on the grounds that the developer in
Gassaway
knew of the risk created by the drainage facilities and could have reasonably foreseen the damage that ultimately occurred. It concluded that, because the damages caused by the developer’s failure to disclose the presence of the sewer were not the result of an accident, the insurance company was not obligated to provide coverage.
Gassaway,
As noted by the district court in the present case, the complaint in the underlying state-court action “alleges that McGowan failed to adequately inspect and resolve the condition of the tree.” The district court concluded that “McGowan’s alleged negligence does not suggest any intent to cause harm or to overlook a risk of harm .... The underlying lawsuit ... suggests he did not know the tree’s condition or know that allowing it to remain would pose a risk of harm to the occupants of the apartment building.” Because the fall of the tree was unforeseen, unexpected, and fortuitous, McGowan’s negligent omission constituted an accident as the term is used in insurance policies.
See Standard Constr. Co. v. Md. Cas. Co.,
State Farm, however, argues that it does not have a duty to defend McGowan because
[a]n “occurrence” for coverage purposes is the point in time when actionable negligence arises, which is when an injury or damage is caused and results from the breach of duty owed. The ultimate question for coverage is not when McGowan may have committed a negligent act, but instead the time when his acts or omissions may have arisen to the level of negligence actionable at law.
In support of its argument, State Farm correctly recites the elements of actionable negligence.
See McClung v. Delta Square Ltd.,
State Farm repeatedly asserts that a negligent act alone is not an occurrence. To bolster its argument, it notes that the insurance policy provides that the occurrence must result in “bodily injury” in order for State Farm to be liable. This is undoubtedly true, but the policy does not specify
when
the bodily injury must take place. Moreover, the Tennessee Supreme Court has specifically held that “the negligent acts of an insured can be an accident as this word is used in insurance policies.”
Gassaway,
State Farm attempts to distinguish
Gassaway
from the present case on the ground that “[t]he
Gassaway
[sic] decision did not address the question of
timing
for policy application purposes.” It then cites the following three cases that stand for the proposition that the term “occurrence” means the time when the claimant is injured, not the time of the negligent act or omission:
State Auto Mutual Insurance Co. v. Shelby Mutual Insurance Co.,
No. 1162,
Two of these cases,
State Auto Mutual Insurance Co.
and
Monticello Insurance Co.,
are readily distinguishable from the
*439
present case in that the policies at issue in both cases specifically limited coverage based on the timing of the injury.
See State Auto Mut. Ins. Co.,
State Farm argues that the words “at any time” in the definition of “bodily injury” are intended to clarify that death resulting from an injury need not occur during the policy period. It maintains that the mortal injury must occur during the policy period for coverage to apply, even if the injured individual does not die until after the expiration of the policy. We agree that the absence of a comma before the phrase “at any time” suggests that State Farm may have intended for the phrase to modify “death” and not “bodily injury.” On the other hand, we can also see how one might reasonably read the definition to mean that the injury itself can occur at any time. In that case, a plausible interpretation of the policy would be that the occurrence must take place during the policy period, but that the resulting injury can happen either during the policy period or after the policy has expired.
The policy is therefore ambiguous as to when the injury must occur. Tennessee law requires that ambiguities of this nature must be resolved in favor of the insured.
Am. Justice Ins. Reciprocal v. Hutchison,
Turning now to the third case relied on by State Farm, the unpublished Delaware decision in
Shreckengast,
we acknowledge that the facts are strikingly similar to those in the present case. In
Shrecken-gast,
a tree fell onto an apartment building owned by the plaintiffs, causing personal injuries and significant property damage. The insurance policy issued to the plaintiffs provided for coverage of an “occurrence which takes place during the policy period” and defined “occurrence” in the same terms as in the present case. Concluding that the “occurrence” was the falling of the tree, rather than the deterioration of the tree’s roots, the Delaware court held that the plaintiffs could not recover under the policy “because the triggering ‘occurrence’ took place after the policy terminated.”
Shreckengast
is nevertheless unpersuasive for several reasons. Aside from being an unpublished decision from another jurisdiction, the case does not mention the policy’s definition of “bodily injury,” which is relevant because the definition in the present case arguably provides that the injury can occur “at any time.” Moreover,
Shreckengast
fails to resolve the ambiguities in the policy in favor of the insured, as
*440
Tennessee law requires.
See Hutchison,
In the present case, because we conclude that the meaning of the term “occurrence” is ambiguous, the policy language that limits coverage must be construed in favor of the insured. See id. We therefore resolve any doubts regarding whether the occurrence took place within the policy period in favor of McGowan.
III. CONCLUSION
For all of the reasons set forth above, we AFFIRM the judgment of the district court.
