Earlier this month, the California Supreme Court agreed to review Montrose Chemical Corporation’s appeal from a September appellate court ruling that rejected Montrose’s preferred “vertical exhaustion” method of exhausting excess-layer policies in favor of a policy-by-policy review to determine which policies are triggered. The California high court’s grant of Montrose’s petition for review is potentially significant in clarifying the appropriate excess policy exhaustion trigger under California law, not to mention in addressing a significant insurer defense in Montrose’s longstanding coverage dispute over environmental insurance coverage, which has been winding its way through California courts for more than 25 years.

In a recent Client Alert, Hunton & Williams insurance attorneys Lorelie Masters, Michael Levine, and Geoffrey Fehling discuss the importance of reviewing historical liability insurance policies and the potential benefit these policies can have on minimizing exposure to environmental hazards. In Cooper Industries, LLC v. Employers Insurance of Wausau, et al., No. L-9284-11 (N.J. Super. Ct. Law Div. Oct. 16, 2017), a New Jersey trial court held that an electrical products manufacturer was entitled to coverage rights under commercial general liability policies issued to a predecessor company for environmental remediation costs stemming from a U.S. Environmental Protection Agency cleanup of a 17-mile stretch of the Passaic River in New Jersey.

On May 27, 2016, the U.S. District Court for the Western District of Washington allowed a declaratory judgment action filed by the Seattle Times Company for excess coverage to proceed to trial despite the insurer's arguments that the underlying policies had not been exhausted.
