Case No. 24-4024

UNITED STATES COURT OF APPEALS FILED FOR THE SIXTH CIRCUIT Aug 13, 2025 KELLY L. STEPHENS, Clerk

THOMAS D. RABLE, Administrator of the ) ) estate of Atsushi Tanaka, deceased, ) ON APPEAL FROM THE UNITED Plaintiff-Appellant, ) STATES DISTRICT COURT FOR ) THE NORTHERN DISTRICT OF v. ) OHIO ) SOMPO AMERICA INSURANCE ) OPINION COMPANY, ) Defendant-Appellee. ) )

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
