On Tuesday, May 3, 2016, the New York Court of Appeals held that each of several excess liability insurers can be wholly responsible for the entire extent of their policyholders' asbestos liabilities.  The Court further held that "vertical" exhaustion would apply; rejecting the insurers' attempt to apply "horizontal" exhaustion before upper-layer policies must respond.  The decision, in In the Matter of Viking Pump, Inc. and Warren Pumps, LLC, Insurance Appeals, comes in response to two questions certified from the Delaware Supreme Court:
