Before: SILER, KETHLEDGE, and BUSH, Circuit Judges.
SILER, Circuit Judge. Atsushi Tanaka died in a car accident with an allegedly
underinsured semitruck. Tanaka’s Estate sued Sompo America Insurance Co. for underinsured
motorist coverage and umbrella coverage under his employer’s insurance policies. The district
court dismissed the Estate’s claims because the policies do not provide coverage. We affirm.
I.
Thomas Rable administers the Estate of Atsushi Tanaka, who died in a 2022 collision with
a semitruck that had stopped in the road in front of him and reversed to avoid missing a turn. The
semitruck driver’s insurance company paid the Estate its $1 million policy limit minus a $7,043.98
property-damage lien, but the Estate calculated its damages at over $2.1 million. The Estate sought
the excess from Sompo America Insurance Company, Tanaka’s employer’s insurance company,
under its $1 million underinsured-motorist (UIM) endorsement attached to its auto policy and
under its $10 million umbrella policy, but Sompo refused to pay. No. 24-4024, Rable v. Sompo Am. Ins. Co.
The Estate sued Sompo in Ohio state court, asserting claims for declaratory judgment,
breach of contract, and bad-faith denial of coverage. Sompo removed the lawsuit to federal court
and moved to dismiss the complaint, arguing that the Estate has no right to recover under the
policies. The district court granted the motion, explaining that the semitruck was not underinsured
because the Estate had received $1 million—the same as the UIM policy limit—from the
semitruck’s insurer and that the umbrella policy unambiguously does not provide UIM coverage.
Rable appeals.
II.
We review both the district court’s decision to dismiss the complaint and its interpretation
of the insurance policy de novo. Dakota Girls, LLC v. Philadelphia Indem. Ins. Co., 17 F.4th 645,
648 (6th Cir. 2021). Because we sit in diversity, we apply Ohio substantive law, id., which
interprets insurance policies using standard contract rules, Acuity, A Mut. Ins. Co. v. Progressive
Specialty Ins. Co., 229 N.E.3d 1, 4 (Ohio 2023). We assume that a contract’s language reflects
the parties’ intent, and we apply “the plain meaning of the policy’s language ‘unless another
meaning is clearly apparent from the contents of the policy.’” Motorists Mut. Ins. Co. v. Ironics,
Inc., 200 N.E.3d 149, 155 (Ohio 2022) (citation omitted). If the insurance policy’s terms are
unambiguous, we “look no further than the writing itself to determine the parties’ intent[,]” but if
the terms are ambiguous—“susceptible to more than one reasonable interpretation”—we interpret
them against the insurer. Id. at 155–56. “[O]ne seeking to recover on an insurance policy generally
has the burden of proving a loss and demonstrating coverage under the policy.” Sanzotta v. Devor,
208 N.E.3d 193, 199 (Ohio Ct. App. 2023) (quoting Inland Rivers Serv. Corp. v. Hartford Fire
Ins. Co., 418 N.E.2d 1381, 1383 (Ohio 1981)). “We ‘may affirm [the district court] on any ground
2 No. 24-4024, Rable v. Sompo Am. Ins. Co.
supported by the law and the record.’” Fisher v. Perron, 30 F.4th 289, 296 (6th Cir. 2022) (citation
omitted).
III.
The Estate argues that it is entitled to coverage under the UIM endorsement to the auto
policy and under the umbrella policy because it incorporates the UIM endorsement.
The UIM endorsement to the auto policy covers the compensatory damages that an insured
is entitled to recover from an underinsured vehicle. The UIM endorsement defines an underinsured
vehicle as:
[A] land motor vehicle for which the sum of all liability bonds or policies applicable at the time of an “accident” is either: a. Less than the limit of liability for this coverage; or b. Reduced by payments to others injured in the “accident” to an amount which is less than the limit of liability for this coverage.
A.
The semitruck was not an underinsured vehicle under subsection (a) of the definition. The
Estate does not dispute that the semitruck was insured for $1 million—the same as the Sompo
UIM endorsement limit. Instead, the Estate argues that policy language requires us to compare
the semitruck’s $1 million policy limit to the umbrella policy’s $10 million policy limit. We
disagree.
Under the UIM endorsement, a vehicle is underinsured if the sum of the “policies
applicable” to it are less than the liability limit for “this coverage[.]” Nothing suggests that a
reference to “this coverage” within the UIM endorsement refers to the separate umbrella policy—
the underlying insurance documents refer to the separate parts, including the UIM endorsement,
as “coverages,” suggesting that “this coverage” does not refer to all the insurance policies
applicable to Tanaka. See This, Merriam-Webster.com, https://www.merriam-
3 No. 24-4024, Rable v. Sompo Am. Ins. Co.
webster.com/dictionary/this (defining “this” as “being the person, thing, or idea that is present or
near in place, time, or thought or that has just been mentioned” or “being the nearer at hand or
more immediately under observation or discussion”). The plural “policies” in “policies
applicable” likewise does not point to the umbrella policy because it refers to those applicable to
the allegedly underinsured vehicle, not the insured.
As a fallback, the Estate contends that because the umbrella policy’s declaration page lists
the auto policy, and the auto policy includes UIM coverage, the umbrella policy includes UIM
coverage up to its $10 million limit or is at least ambiguous.
Ohio courts have rejected the idea that an umbrella policy automatically adopts the
coverages of underlying policies. In Gilkey v. Grange Mutual Casualty Co., No. 16-CA-12, 2016
WL 6600001 (Ohio Ct. App. Nov. 1, 2016), an insured sought UIM coverage from an umbrella
policy based on the same argument the Estate brings here—that because the umbrella policy’s
declarations page listed the underlying policy that included UIM coverage, the umbrella policy
must also include UIM coverage or at least be ambiguous. Id. at *2. The Ohio Court of Appeals
rejected that argument because the declarations page identified the underlying coverages to notify
the insured that the underlying policies must be active to receive umbrella coverage—it did not
say it was incorporating the underlying policies’ coverages into the umbrella policy. Id. at *4.
The court explained that umbrella coverage “does not drop down to ‘cover’ underinsured motorist
liability” and “need not provide the same coverage as an underlying insurance policy.” Id. at *4–5.
What matters is whether the umbrella policy’s language, read in its entirety, incorporates the UIM
benefits. Id.; see Arn v. McLean, 825 N.E.2d 181, 188 (Ohio Ct. App. 2005) (rejecting a similar

WL 6600001 (Ohio Ct. App. Nov. 1, 2016), an insured sought UIM coverage from an umbrella

What matters is whether the umbrella policy’s language, read in its entirety, incorporates the UIM
benefits. Id.; see Arn v. McLean, 825 N.E.2d 181, 188 (Ohio Ct. App. 2005) (rejecting a similar
argument because an umbrella policy does not cover risks that the underlying policy does not cover
4 No. 24-4024, Rable v. Sompo Am. Ins. Co.
and “[b]y the same token, the mere fact that a particular type of risk is covered in an underlying
policy does not mean that it is also covered by the umbrella policy”).
The Estate insists that Gilkey and Arn are distinguishable and that we should instead follow
Switalski v. Clevenger, No. 360391, 2023 WL 5313038, at *5 (Mich. Ct. App. Aug. 17, 2023), in
which the Michigan Court of Appeals accepted the same argument. But Gilkey and Arn are not
meaningfully distinguishable. True, in each, the Ohio Court of Appeals had additional reasons to
deny umbrella coverage, but it still rejected versions of the Estate’s argument and underscored the
importance of a comprehensive reading of the policy language. Gilkey, 2016 WL 6600001, at *4–
5; Arn, 825 N.E.2d at 188. We are not free to ignore those cases. Absent an Ohio Supreme Court
case on point, we make an “Erie guess” about how it would decide, viewing Ohio Court of Appeals
decisions as persuasive “unless it is shown that the state’s highest court would decide the issue
differently.” Innovation Ventures, LLC v. Custom Nutrition Lab’ys, LLC, 912 F.3d 316, 334 (6th
Cir. 2018) (quoting Conlin v. Mortg. Elec. Registration Sys., Inc., 714 F.3d 355, 359 (6th Cir.
2013)). The Estate cites nothing that suggests the Ohio Supreme Court would decide differently.
Turning to the policy language, we conclude that the umbrella policy unambiguously does
not provide UIM coverage. First, the umbrella policy only covers damages for which the insured
is liable, not damages the insured suffered. It “pay[s] on behalf of the insured the ‘ultimate net
loss’ in excess of the ‘retained limit’ because of ‘bodily injury’ or ‘property damage’ to which this
insurance applies.” The “ultimate net loss” is “the total sum, after reduction for recoveries or
salvages collectible, that the insured becomes legally obligated to pay as damages by reason of
settlement or judgments[.]”
Nothing in the umbrella policy suggests that listing the underlying auto policy on the
declarations page incorporates the UIM endorsement, and the ultimate-net-loss provision confirms
5 No. 24-4024, Rable v. Sompo Am. Ins. Co.
that the parties never intended it to. See Blake v. Thornton, 914 N.E.2d 1102, 1106–07 (Ohio Ct.
App. 2009) (interpreting a similar provision in an umbrella policy and holding that the policy
provided excess coverage for liability to third parties, so it unambiguously did not provide UIM
coverage, despite the umbrella policy’s listing the underlying insurance on its schedule page);
Seifke v. Bond, No. 22333, 2008 WL 3586902, at *1, *5 (Ohio Ct. App. Aug. 15, 2008) (same);
Gilkey, 2016 WL 6600001, at *4 (similar, where the umbrella policy stated that it did not cover
bodily injury to the insureds). The Estate’s contrary authority is not from Ohio and is inapposite
because those policies contained contradictory language excluding but seemingly including UIM
coverage. See Lindsay v. Owners Ins. Co., No. CIV. 12-5066, 2013 WL 12412013, at *4–6 (D.S.D.
July 25, 2013); Stubbe v. Guidant Mut. Ins. Co., 651 N.W.2d 318, 323–24 (Wis. Ct. App. 2002).
Second, the umbrella policy only mentions UIM coverage in two places, and neither
incorporates UIM coverage. One is in a provision adding exclusions for “if Excess Uninsured
and/or Underinsured Motorists Coverage is attached,” but UIM coverage is not listed in the
umbrella policy’s “schedule of coverage forms and endorsements attached to this policy[.]” The
other is in a provision excluding UIM coverage by operation of law. Excluding UIM coverage by
operation of law makes sense in a policy that does not itself provide UIM coverage. An explicit
provision excluding UIM coverage is unnecessary because a policy need not exclude coverage that
it does not provide. Blake, 914 N.E.2d at 1104, 1108–09 (concluding that there was no UIM
coverage under umbrella policy that didn’t specifically exclude UIM coverage but excluded it
under operation of law).
B.
The Estate fares no better under subsection (b) of the definition. It argues that because the
$1 million payment from the semitruck’s insurer was reduced by a $7,043.98 property-damage
6 No. 24-4024, Rable v. Sompo Am. Ins. Co.
lien, it was “[r]educed by payments to others injured in the ‘accident’ to an amount which is less
than the limit of liability for this coverage.”
Under Ohio law, UIM coverage “is not and shall not be excess coverage to other applicable
liability coverages” and “shall be reduced by those amounts available for payment under all
applicable bodily injury liability bonds and insurance policies covering persons liable to the
insured.” Ohio Rev. Code § 3937.18(C). The insured’s expenses, like a lien from the insured’s
medical treatment or the insured’s attorneys’ fees, still count toward the UIM policy limit, but
another’s expenses, like a medical lien for services provided to someone else, do not. Gilliland v.
Nationwide Prop. & Cas. Ins. Co., 936 N.E.2d 524, 526–29 (Ohio Ct. App. 2010) (summarizing
applicable caselaw). The district court concluded that the lien counted toward the UIM policy
limit, so the reduction could not entitle the Estate to additional UIM benefits.
The Estate now describes the lien as “a claim of an unrelated party seeking money for
property damages caused by the [semitruck driver’s] recklessness[,]” so in its view, it was the
semitruck driver’s responsibility and should not count toward the UIM coverage limit. But the
complaint contains no information about the nature of the lien—the Estate raises that factual
allegation for the first time in its appellate brief. “We ‘will not entertain on appeal factual
recitations not presented to the district court when reviewing a district court’s decision.’” Martinez
v. Wayne County, -- F.4th --, No. 24-1474, 2025 WL 1733451, at *11 (6th Cir. June 23, 2025)
(quoting Bormuth v. County of Jackson, 870 F.3d 494, 500 (6th Cir. 2017) (en banc)); see Harvey
v. Great Seneca Fin. Corp., 453 F.3d 324, 328 (6th Cir. 2006).
The Estate asks us to look at the language of the UIM policy rather than Ohio’s prohibition
of excess recovery. But even if we did, the Estate’s bare allegation that the $1 million was reduced
by a property-damage lien hardly alleges that the $1 million was “[r]educed by payments to others
7 No. 24-4024, Rable v. Sompo Am. Ins. Co.
injured in the ‘accident[.]’” See Dakota Girls, LLC, 17 F.4th at 651 (affirming the district court’s
dismissal of insurance-coverage claims when the plaintiff alleged facts consistent with breach of
the policy rather than the specific facts the policy term required).
IV.
Because we conclude that the Estate is not entitled to coverage under the UIM endorsement
to the auto policy or under the umbrella policy, we affirm the district court’s dismissal of the
Estate’s claims.
AFFIRMED.
