¶ 1. Susann Humphrey was seriously injured when the car in which she was a passenger was struck, head-on, by another automobile. The driver of the car in which Ms. Humphrey was a passenger was insured by State Farm Mutual Insurance Company (State Farm). Ms. Humphrey had an automobile insurance policy with Vermont Mutual Insurance Company (Vermont Mutual). She brought suit to еnforce uninsured/ underinsured motorist (UM/UIM) provisions in both the Vermont Mutual and the State Farm policies. State Farm filed a motion for summary judgment with regard to its obligations to Ms. Humphrey. The superior court granted State Farm’s motion, and Vermont Mutual appealed. We affirm.
¶ 2. The relevant facts are not in dispute. On February 5, 2005, Ms. Humphrey was riding in the back seаt of a car owned and driven by a friend when the tortfeasor crossed the center line of the road and collided with the friend’s vehicle. Liability for the accident rested completely with the tortfeasor. The tortfeasor was insured by Allstate Insurance Company (Allstate) with liability coverage of $100,000, which, with the consent of Ms. Humphrey’s insurers, Allstate tendered and Ms. Humphrey accepted. The tortfeasor was then released from this litigation. Ms. Humphrey asserted a claim against State Farm and Vermont Mutual for damages in excess of the amount covered by the tortfeasor’s insurance.
¶ 3. The driver’s State Farm policy provided UM/UIM coverage of $50,000 per person аnd $100,000 per accident. The State Farm policy contained the following “other insurance” provision, the purpose of which was to establish priority of payment when multiple UM/UIM policies applied:
If There Is Other Coverage
1. If the insured sustains bodily injury. *538 a. as a pedestrian and other uninsured motor vehicle coverage applies; or
b. while occupying your car, and your car is described on the declаrations page of another policy providing uninsured motor vehicle coverage, we are liable only for our share. Our share is that percentage of the damages that the hmit of liability of this coverage bears to the total of all such uninsured motor vehicle coverage applicable to the accident.
2. If the insured sustains bodily injury while occupying a vehicle which is not your car, this coverage applies as excess to any uninsured motor vehicle coverage which applies to the vehicle as the primary coverage. If coverage under more than one pohcy applies as excess, we are hable only for our share. Our share is that percent of the damagеs that the limit of liability of the coverage bears to the total of all uninsured motor vehicle coverage applicable as excess to the accident.
¶ 4. Ms. Humphrey’s Vermont Mutual policy provided $300,000 of UM/UIM coverage. That pohcy contained the following “other insurance” provision:
OTHER INSURANCE
If there is other applicable insurance similar to the insurance provided under this Part of the policy, we will pay only our share of the loss. Our share is that proportion that our Hmit of liability bears to the total of aU applicable limits. However, any insurance we provide with respect to a vehicle you do not own shall be excess over any оther collectible insurance similar to the insurance provided under this Part of the poHcy.
¶ 5. In August 2007, Ms. Humphrey filed a complaint in superior court alleging that she had made a demand pursuant to the UIM poHcy limits from State Farm and Vermont Mutual, that they had refused her demands, and that they had breached their contractual duties by failing to pаy damages for bodily injury. State Farm moved for summary judgment, claiming that the tortfeasor’s $100,000 HabiHty payment completely offset its $50,000 per person UIM coverage and nullified its obfigation to Ms. Humphrey. Vermont Mutual argued that the $100,000 offset should be shared between it and State Farm on a proportional basis. The superior court granted State Fаrm’s motion. It recognized some lack of clarity in the law of Vermont, but concluded that our decision in
State Farm Mutual Auto Insurance Co. v. Powers,
¶ 6. Vermont Mutual appeals, urging us to prorate the credit. By their proposed aHocation method, they would receive the proportion of the credit that their UIM coverage bears to the total UIM coverage, or roughly $86,000 of the $100,000 offset. Vermont Mutual argues that: (1) our decision in Powers does not control the current case; (2) 23 V.S.A. § 941(e) entitles them to a pro rata share of the offset; and (3) pubHc policy considerations favor pro rata aHocation.

¶ 7. We review decisions on motions for summary judgment de novo by applying the same standards as the trial court.
Myers v. LaCasse,
2003 VT 86A, ¶ 15,
¶ 8. Some background in Vermont’s UM/UIM law is required. UM/UIM insurance рrovides coverage when a tortfeasor’s liability insurance is insufficient to compensate the insured. Under 23 V.S.A § 941(a), motor vehicle liability policies delivered or issued in Vermont must include UM/UIM insurance. A vehicle is uninsured if it is either not insured or is covered by an insolvent insurer.
Id.
§ 941(d). A vehicle is underinsured if the liability insurance limits applicable at the time of аn accident are less than the limits of the UM/UIM coverage applicable to the insured.
Id.
§ 941(f). Essentially, the statutory UM/ UIM requirement ensures coverage that fills the gap between a tortfeasor’s liability coverage and an insured party’s UM/ UIM coverage.
Webb v. U.S. Fid. & Guar. Co.,
¶ 9. The insured may “stack” UM/UIM policies. “ ‘Stacking’ refers to the ability of the insured, when covered by more than one insurance policy, to obtain benefits from a second policy on the same claim when recovery from the first policy would be inadequate.”
Monteith v. Jefferson Ins. Co. of N.Y.,
¶ 10. When multiple insurers provide UM/UIM coverage, they may establish priority of payment by designating themselves as either primary or excess in the terms of their policies as long as those terms do not adversely affect the rights of the policyholder.
Powers,
¶ 11. Finally, Vermont law entitles UM/ UIM insurers to subrogation. Under § 941(e), “[i]f payment is made under uninsured motorist coverage, and subject to the tеrms of that coverage, to the extent of that payment, the insurer is entitled to the proceeds of any settlement or recovery from any person legally responsible for the damage or personal injury.” This statutory right of
*540
subrogation “enables a secondarily liable party who has been compelled to pay a dеbt to be made whole by collecting that debt from the primarily hable party, who, in good conscience, should be required to pay.”
Korda v. Chicago Ins. Co.,
¶ 12. The subrogation right established by § 941(e) entitles State Farm and Vermont Mutual to offset the total UIM coverage of $350,000 by the $100,000 Allstate paid on behalf of the tortfeasor. The issue in this case is how to allocаte that offset. We take this opportunity to clarify that our decision in Powers controls this question.
¶ 13. In
Powers,
we decided two issues. First, we considered whether insurers may designate themselves as primary or excess. As explained above, we held that they may.
Powers,
¶ 14. Vermont Mutual argues that because we concluded in
Powers
that the primary insurer was only entitled to a pro rata share, our discussion of allocating the entire offset to the primary insurer was unnecessary to the holding аnd therefore noncontrolling dicta. We disagree. Our conclusion that the primary UIM insurer was entitled to
at least
its pro rata share of the offset rested on cases allocating the entire offset to the primary insurer. Moreover, we explicitly “emphasize[d] that the allocation set forth . . . [was] limited to the circumstances of [that] particular case.”
Id.

¶ 15. Vermont Mutual’s second argument is that applying the offset pro rata preserves all UM/UIM insurers’ statutory right to subrogation in every case, but that applying the offset entirely to the primary coverage will, in some situations, deny an excess UM/UIM insurer subrogation in violation of § 941(e). Essentially, Vermont Mutual argues that § 941(e) creates an entitlement to subrogation for each UM/UIM insurer in each case that would be defeated by any system of apportionment that is not a pro rata system. We find this argument unpersuasive. Under § 941(e), UM/UIM insurers are “entitled to the proceeds of any settlement or recovery from any per
*541
son legally responsible for the damage or personal injury.” Section 941 entitles UM/ UIM insurers to indemnity for amounts that should have been paid by the tortfeasor, and prevents the insured from recovering twice for the same injury. However, as Vermont Mutual concedes, ‘Vermont’s Underinsured Motorist Statute does not directly provide for allocation of the credit created by the liability payment.” We agree; the statute simply does not speak to apportionment. Even so, we must construe § 941(e) according to its purpose and the intent of the Legislature. See
In re Estate of Cote,
¶ 16. We hold that as long as the total UM/UIM coverage is offset by the liability payment, § 941(e) is satisfied. As stated, in so holding, we follow the majority of jurisdictions that have confronted the issue, some of which have also done so with similarly limited statutory guidance. Ga.
Farm Bureau Mut. Ins. Co.,
¶ 17. Vermont Mutual’s third argument is that fairness and public policy require pro rata allocation of the offset. It argues that the policy limits — rather than the insurer’s status as primary or excess insurer — indicate the actual risk taken by insurers, and that allocating the offset based on policy limits will encourage insurers to issue high-limit policies, which will protect the public more effectively than low-limit policies. We find this unpersuasive.
¶ 18. We decline to engage in lengthy analysis about the relative risks assumed between the UM/UIM insurers. We assume that competitive insurers issuing policies in this state are more than capable of assessing risk and setting premiums accordingly. However, we briefly address Vermont Mutual’s fairness argument — that it should be rewarded with a greater portion of the offset because it assumed a higher risk in issuing a higher limit policy. First, we note that an insurer’s reward for taking risk is the premium it collects. Risk-reward equivalency would tend to indicate that the insurer who takes a greater risk by issuing a higher limit policy would be rewarded by collecting higher premiums, see 5 L. Russ
&
T. Segalla, Couch on Insurance § 69:1, at 69-5 (3d ed. 2005) (“The amount of the premium varies in proportion to the risk assumed.”), not that the risk taker should be rewarded if the danger that made the policy risky comes to fruition. Second, we find unpersuasive Vermont Mutual’s suggestion that it faces more risk than State Fаrm despite being
*542
the excess insurer because it has higher policy limits. An insurer faces less risk from the possibility of an accident where its policy provisions make it excess than the primary insurer faces from the same possibility. As we have said before, the denial of any offset to the excess insurer is a logical corollary to the lack of risk it faces until the primary policy is exhausted. Powers,
¶ 19. As a policy matter, Vermont Mutual argues that rewarding insurers for issuing higher limit UM/UIM policies by allocating the offset pro rata will encourage all insurers to issue higher limit policies. They point out that our decision in
Powers
contemplated adopting a rule requiring all insurers to pay on a pro rata basis if a showing of need, based on public policy grounds, was made.
Id.
at 239 n.3,
¶ 20. In order to be fan-, in this context, we need only be consistent. Consistency allows insurers to accurately assess the risk associated with the policies they issue. Premiums will adjust, if necessary, to reflect insurance companies’ exposure to risk based on whatever rale stands. Our decision that the insurer who stands first in line to pay should also stand first in line to collect is consistent with Powers and with the majority of jurisdictions that have addressed the issue.
¶ 21. Because we see no reason to divert from the course we set in Powers, we explicitly hold today that primary UM7 UIM insurers are entitled to offset their coverage by the full amount of a tortfeasor’s liability payment. Any remaining offset inures to the excess insurer’s benefit. Thus, the tortfeasor’s $100,000 liability payment nullifies State Farm’s primary UIM coverage of $50,000 and offsets Vermont Mutual’s excess UIM coverage by $50,000. The trial court properly granted State Farm’s motion for summary judgment.
Affirmed.
