FLAUM, Circuit Judge.

Deanne Berrey was injured in an automobile accident at work. The at-fault driver, who did not work with Berrey, carried liability insurance, but the cost of Berrey's injuries exceeded the insurance policy's limit. Berrey received partial compensation under her employer's workers' compensation scheme but, because her employer was not legally responsible for the accident, state law granted the workers' compensation carrier a lien on any recovery Berrey received from the at-fault driver. To satisfy that lien, the at-fault driver's liability insurer paid its full policy limit directly to the workers' compensation carrier.

Defendant Travelers Indemnity Company of America provided underinsured motorist coverage to Berrey's employer. The policy covered an employee injured by a third-party tortfeasor who did not carry adequate auto insurance to fully compensate the employee for her loss. Pursuant to this policy, Travelers paid Berrey the difference between her total calculated damages and the at-fault driver's policy limit. Berrey claims that Travelers improperly deducted the at-fault driver's insurance payment from the total it owed to Berrey because that payment was made directly to the workers' compensation carrier rather than to Berrey herself. She argues that the language of Travelers's underinsured motorist policy precludes such a deduction. Because we read the language of the policy to support Travelers's calculation and because Berrey's reading would undermine the purpose of underinsured motorist coverage, we disagree and affirm the district court's grant of summary judgment in favor of Travelers.

I. Background

On March 26, 2009, Berrey, an employee of Curry Ice & Coal, Inc., was on duty when her vehicle collided with another driven by Sheri A. Campbell. Campbell, who was not employed by Curry Ice, was found at fault for the accident. An arbitral panel constituted pursuant to an agreement between Berrey and Curry Ice issued a binding opinion, which calculated Berrey's total damages at $310,000, inclusive of all medical expenses.

Berrey, an Illinois resident, initiated three independent proceedings to recover for her injuries: (1) a workers' compensation claim against Curry Ice; (2) a liability claim against Campbell; and (3) an underinsurance claim against Travelers, a Connecticut corporation which provided underinsured motorist ("UIM") coverage to Curry Ice for the vehicle that Berrey was driving at the time of the accident.

Berrey first received $103,224.02 in workers' compensation benefits.1 Pursuant to § 5(b) of the Illinois Workers' Compensation Act, 820 Ill. Comp. Stat. 305, Curry Ice acquired a workers' compensation lien against any recovery that Berrey subsequently obtained from Campbell.2 Campbell's liability insurance carried a policy limit of $100,000, which her insurer paid directly to Curry Ice to satisfy the workers' compensation lien.

The underinsured motorist policy issued to Curry Ice by Travelers (the "Policy") carried a limit of $1 million per accident. Travelers paid Berrey $210,000 — the difference between her total calculated damages ($310,000) and the payment from Campbell's insurer toward the workers' compensation lien ($100,000).

Under the Policy, which covered all vehicles owned by Curry Ice, Travelers agreed to "pay all sums the `insured [employee]' is legally entitled to recover as compensatory damages from the owner or driver of an `underinsured motor vehicle.'" Any recovery is subject to the following limitations:

Berrey claims that, according to these provisions, Travelers owes her an additional $100,000. She first argues that the language of Section D.2 permits only a reduction in the policy limit (here, $1 million) equal to workers' compensation benefits paid, not a reduction in the amount due if the insured's claim falls below the policy limit. Berrey also contends that, under Section D.4, she never "receive[d]" the $100,000 payment from Campbell because it was paid directly to Curry Ice to satisfy the workers' compensation lien; therefore, she would receive no impermissible "duplicate payment[]" if Travelers were to pay her an additional $100,000.

The district court rejected these arguments and awarded summary judgment to Travelers, determining that the $210,000 UIM payment fulfilled Travelers's obligations under the Policy. The court also denied Berrey's subsequent motion to alter or amend the judgment, emphasizing that Berrey received the benefit of the $100,000 paid by Campbell's insurer toward the workers' compensation lien and that awarding Berrey an additional $100,000 would therefore constitute a prohibited double recovery. Berrey appeals.

II. Discussion

We review a district court's award of summary judgment de novo. O'Leary v. Accretive Health, Inc., 657 F.3d 625, 630 (7th Cir.2011). Because our jurisdiction is based on diversity of citizenship, the resolution of substantive issues is governed by the applicable state law. Aeroground, Inc. v. Center-Point Props. Trust, 738 F.3d 810, 813 (7th Cir.2013). The parties agree that Illinois law applies.

The Illinois Supreme Court has noted that the underlying purpose of underinsured motorist coverage is to "place the insured in the same position he would have occupied if the tortfeasor had carried adequate insurance." Phoenix Ins. Co. v. Rosen, 242 Ill.2d 48, 350 Ill.Dec. 847, 949 N.E.2d 639, 646 (2011) (citation and internal quotation marks omitted). The legislative history of § 143a-2 of the Illinois Insurance Code, 215 Ill. Comp. Stat. 5, which establishes the parameters of UIM coverage, confirms that it serves to "fill the gap between the claim and the amount available from the underinsured." Sulser v. Country Mut. Ins. Co., 147 Ill.2d 548, 169 Ill.Dec. 254, 591 N.E.2d 427, 430 (1992) (quoting 81st Gen. Assemb., House Proceedings 44-45 (Ill.1980)). UIM coverage is not intended to permit an injured employee to collect more than she would have been entitled to receive from the tortfeasor alone.

Here, if Campbell had carried liability insurance in the amount of $310,000 (Berrey's total damages) rather than $100,000, Campbell's policy would have fully compensated Berrey for her loss. Of that hypothetical $310,000 insurance payment, $103,224.02 would have been paid to Curry Ice to satisfy the workers' compensation lien and the remainder ($206,775.98) would have gone to Berrey. In reality, Berrey has $210,000 (the UIM payment from Travelers) in her possession, and the workers' compensation lien has been satisfied via the $100,000 payment from Campbell's insurer.3 She is therefore already in a marginally better position than she would have occupied had Campbell carried adequate insurance. Awarding Berrey an additional $100,000 would leave her with $310,000 in pocket, plus the $103,224.02 she received in workers' compensation benefits, for a total of over $413,000 in damages — an unmerited windfall that far exceeds the arbitral panel's damages calculation. To permit such a double recovery would flout the stated purpose behind Illinois's underinsured motorist coverage scheme.

The plain meaning of the Policy language also contradicts Berrey's position. Illinois law requires us to interpret an insurance policy as a whole, taking into consideration the type of insurance purchased, the overall purpose of the contract, and the nature of the risks involved. Am. States Ins. Co. v. Koloms, 177 Ill.2d 473, 227 Ill.Dec. 149, 687 N.E.2d 72, 75 (1997). The policy's language must be construed according to the general rules of contract interpretation: so long as the language is unambiguous, it will be enforced as written, but only to the extent that it does not contravene public policy. Hobbs v. Hartford Ins. Co. of the Midwest, 214 Ill.2d 11, 291 Ill.Dec. 269, 823 N.E.2d 561, 564 (2005). In the event of an ambiguity, the policy's terms should be construed strictly against the drafter (here, Travelers). Am. States Ins. Co., 227 Ill.Dec. 149, 687 N.E.2d at 75. However, a policy will be considered ambiguous only where its language is subject to more than one reasonable interpretation — we "will not strain to find an ambiguity where none exists." Hobbs, 291 Ill.Dec. 269, 823 N.E.2d at 564. Considered in the context of the Policy as a whole, we conclude that the language of Section D.4 is susceptible to only one reasonable interpretation.

As an initial matter, Berrey correctly points out that Section D.2 refers specifically to policy limits — that is, the maximum amount of underinsurance available — not the payment due on a claim whose value is less than the applicable policy limit. Because here the $1 million policy limit is significantly higher than Berrey's total damages ($310,000), the question of limit reductions is irrelevant and Section D.2 is inapplicable.4

Instead, Section D.4 is determinative. It specifies, "No one will be entitled to receive duplicate payments for the same elements of `loss' under this Coverage Form and any Liability Coverage Form." Berrey contends that this provision is not implicated because she never "receive[d]" the $100,000 payment from Campbell's insurer. Because that amount was paid directly to Curry Ice to satisfy the workers' compensation lien, as opposed to being paid first from Campbell's insurer to Berrey and then from Berrey to Curry Ice, she claims that the requested $100,000 from Travelers would not constitute a duplicate payment.

However, the simple act of cutting out the middleman cannot alter the conclusion that Berrey "receive[d]" Campbell's payment within the meaning of Section D.4. Although the $100,000 was not paid directly to her, she obtained the full benefit of that payment in its satisfaction of the workers' compensation lien. Had Campbell made the $100,000 payment directly to Berrey, Berrey would have been obligated to apply that payment toward the workers' compensation lien herself. See Sulser, 169 Ill.Dec. 254, 591 N.E.2d at 428. Further, according to Illinois law, Campbell's insurer would have risked liability under the lien if it had not paid the $100,000 directly to Curry Ice. Under the Illinois Workers' Compensation Act, once an insurer receives notice of a workers' compensation lien, it may not enter into a settlement agreement with an injured employee without the consent of her employer. See 820 Ill. Comp. Stat. 305/5(b) ("No release or settlement of claim for damages by reason of [employee's injury by a third party] ... shall be valid without the written consent of both employer and employee...."); see also Hartford Accident & Indem. Co. v. D.F. Bast, Inc., 56 Ill.App.3d 960, 14 Ill.Dec. 550, 372 N.E.2d 829, 833 (1977).

Given the structure of the Illinois workers' compensation scheme, the fact that Campbell's insurer paid the $100,000 directly to Curry Ice — presumably as a matter of convenience — had no practical effect on the amount that Berrey walked away with at the end of the day. To hold, based on a mere technicality, that Berrey did not "receive" the $100,000 payment would be to unreasonably interpret Section D.4, and Illinois law permits us to consider only reasonable interpretations of insurance policy language. See Hobbs, 291 Ill.Dec. 269, 823 N.E.2d at 564.

Berrey relies almost exclusively on the Illinois Appellate Court opinion, Roberts v. Northland Insurance Co., 291 Ill.App.3d 727, 226 Ill.Dec. 268, 685 N.E.2d 371 (1997), overruled on other grounds by 185 Ill.2d 262, 235 Ill.Dec. 579, 705 N.E.2d 762 (1998), to support her reading of the term "receive." In Roberts, the court calculated the amount by which UIM coverage providers could reduce their policy limits via a setoff of workers' compensation benefits paid. At first glance, the facts appear similar to those of the instant case: Roberts was injured on the job by an underinsured third-party tortfeasor and was partially compensated for his loss through a combination of workers' compensation benefits, the tortfeasor's liability insurance, and underinsured motorist coverage. Id. 226 Ill.Dec. 268, 685 N.E.2d at 372. The applicable policy provisions allowed the UIM coverage providers to reduce their policy limits by amounts received both from workers' compensation and from the tortfeasor. Id. Roberts's total estimated damages were in excess of $1 million. 235 Ill.Dec. 579, 705 N.E.2d at 763. He received $246,114.26 in workers' compensation benefits. 226 Ill.Dec. 268, 685 N.E.2d at 372. The tortfeasor's liability coverage, which was limited to $50,000, was applied directly to the workers' compensation lien. Id. 226 Ill.Dec. 268, 685 N.E.2d at 374. At issue was whether the UIM providers could deduct $246,114.26 from their policy limits as a setoff for workers' compensation benefits paid or whether they were limited to a deduction of only $196,114.26 — the difference between the workers' compensation benefits and the $50,000 payment from the tortfeasor.

In holding that a deduction of only $196,114.26 was appropriate, the court concluded that, because Roberts "did not actually recover the $50,000" from the tortfeasor but rather, that amount was applied directly to the workers' compensation lien, the trial court did not err in denying a setoff for the full $246,114.26.5 Id.

Although on appeal, the Illinois Supreme Court did not directly address the question of whether Roberts received the $50,000 payment from the tortfeasor's insurance carrier, the court noted in its recounting of the factual history that the tortfeasor's liability insurer had "paid [Roberts] $50,000 pursuant to [the tortfeasor's] policy." 235 Ill.Dec. 579, 705 N.E.2d at 763. This phrasing casts doubt on the appellate court's conclusion that Roberts did not "recover" that payment. As the district court below correctly observed, "Nothing in the Illinois Supreme Court's opinion reflects the Illinois Appellate Court's `finding' that [Roberts] never received $50,000 from the tortfeasor because it was applied to the workers' compensation lien." Berrey v. Travelers Indem. Co. of Am., No. 11-3426, at 10-11 (C.D.Ill. Nov. 20, 2013).

Further, regardless of whether we must accept the appellate court's characterization of the tortfeasor's insurance payment, Roberts is not controlling here. Roberts dealt with reductions in policy limits rather than in amounts due. There, the court grappled with the limits of coverage under a UIM policy where the plaintiff's actual damages exceeded any potentially applicable policy limit. Roberts's actual damages totaled more than $1 million while the available UIM coverage was limited to $820,000, before any deductions for workers' compensation benefits received or payments made by the tortfeasor. 226 Ill.Dec. 268, 685 N.E.2d at 372. Given a maximum limit less than the total amount of Roberts's damages, the Roberts court faced a situation where, no matter how strict its ruling on setoffs, Roberts would remain undercompensated for his loss. Whatever the reasoning of the Roberts court's denial of the $50,000 setoff, that denial simply ensured that less of Roberts's damages went unpaid — it did not create a scenario that placed Roberts in a better position than he would have occupied had the tortfeasor carried liability insurance sufficient to compensate him for his loss. The court's refusal to allow the $50,000 UIM limit reduction did not permit Roberts a double recovery.

By contrast, Travelers's UIM insurance policy carries a limit of $1 million — an amount that far exceeds any actual damages Berrey incurred. To refuse to consider the $100,000 payment from Campbell's insurer as an amount that Berrey "receive[d]" would lead to an impermissible double recovery, leaving Berrey better off than she would have been had Campbell possessed sufficient insurance. The Roberts court faced no such contravention of the purpose underlying UIM coverage. As a result of this crucial distinction, Roberts does not bind us here.

III. Conclusion

For the foregoing reasons, we AFFIRM the district court's grant of summary judgment in favor of Travelers.
