   HOLLAND, Justice:

This is a consolidated appeal in an insurance-coverage dispute from separate trial court judgments by the Court of Chancery and the Superior Court. Viking Pump, Inc. (“Viking”) and Warren Pumps, LLC (“Warren”) seek to recover under insurance policies issued to a third company: Houdaille Industries, Inc. (“Houdaille”). The litigation first arose in 2005, when Viking brought suit in the Court of Chancery claiming that it was the successor to insurance policies that the Liberty Mutual Insurance Company (“Liberty”) had issued to Houdaille or, in the alternative, seeking partition of the Liberty policy limits. Liberty, Viking, and Warren settled their dispute.

Court of Chancery

Viking and Warren then filed new complaints in the Court of Chancery against more than twenty other insurers that had issued excess policies to Houdaille. The parties cross-moved for summary judgment, inter alia, on how to allocate the losses where, as here, the underlying asbestos injuries potentially trigger coverage across multiple policy periods.

With regard to allocation, the Court of Chancery found a split in authority: some jurisdictions adopt a “joint and several” rule that allows the insured to pick a triggered policy and collect in full up to policy limits; other courts allocate liability according to each triggered period’s “pro rata” share. The Court of Chancery acknowledged that New York’s highest court had rejected “joint and several allocation as “not consistent” with standard policy language, also included in the policies here, limiting coverage to injury “‘during the policy period.’

The Court of Chancery distinguished Consol Edison of N.Y., Inc. v. Allstate Ins. Co. on the ground that the policies here contain additional provisions — “Non-Cu-mulation” and “Prior Insurance” provisions — that the Chancery Court viewed as inconsistent with pro rata allocation. The Umbrella Policies all contain the following Non-Cumulation Provisions:

If the same occurrence gives rise to personal injury, property damage or advertising injury or damage which occurs partly before and partly within any annual period of this policy, the each occurrence limit and the applicable aggregate limit or limits of this policy shall be reduced by the amount of each payment made by [Liberty Mutual] with respect to such occurrence, either under a previous policy or policies of which this is a replacement, or under this policy with respect to previous annual periods thereof.

Twenty-eight of the Excess Policies follow form to this language.

Similarly, seventeen of the Excess Policies, and all of the Policies which do not incorporate the Non-Cumulation Provisions, have substantively identical Prior Insurance Provisions which generally state that:

It is agreed that if any loss covered hereunder is also covered in whole or in part under any other excess Policy issued to the Insured prior to the inception date hereof, the limit of liability hereon stated in the Items 5 and 6 of the Declarations shall be reduced by any amounts due to the Insured on account of such loss under such prior insurance.
Subject to the foregoing paragraph and to all the other terms and conditions of this Policy in the event that personal injury or property damage arising out of an occurrence covered hereunder is continuing at the time of termination of this Policy the Company will continue to protect the Insured for liability in respect of such personal injury or property damage without payment of additional premium.

The Court of Chancery held that the Houdaille policies unambiguously provide for all sums allocation.

Superior Court

Following the Court of Chancery proceedings, the case was transferred to the Superior Court to hear and determine several other issues, one of which was whether the excess policies were subject to vertical or horizontal exhaustion. In a post-trial opinion dated October 31, 2013, the Superior Court held that, as a matter of New York law, Viking Pump and Warren were obligated to horizontally exhaust all triggered “primary and umbrella insurance layers before tapping” any of Houdaille’s excess coverage. In a subsequent opinion dated February 28, 2014, the Superior Court clarified that this horizontal-exhaustion requirement was limited to the primary and umbrella coverage layers.

The legal insurers in this appeal are controlled by New- York law. Section 500.27 of the New York Rules of Court authorizes certification of cases to the New York Court of Appeals “[wjhenever it appears to ... a court of last resort of any other state that determinative questions of New York law are involved in a case pending before that court for which no controlling precedent of the Court of Appeals exists....” We have concluded that a resolution of this appeal depends on significant and unsettled questions of New York law that have not been answered, in the first instance, by the New York Court of Appeals.

Certified, Questions

This Court hereby certifies the following questions to the New York Court of Appeals:

1. Under New York law, is the proper method of allocation to be used all sums or pro rata when there are non-cumulation and prior insurance provisions?
2. Given the Court’s answer to Question # 1, under New York law and based on the policy language at issue here, when the underlying primary and umbrella insurance in the same policy period has been exhausted, does vertical or horizontal exhaustion apply to determine when a policyholder may access its excess insurance?

We direct the Clerk of this Court to send this opinion to the Clerk of the New York Court of Appeals, as our certificate, together with the parties’ briefs and appendices. We will take no further action in this appeal until after the New York Court of Appeals acts on this certification request.
