In the case of County of San Bernardino v. Insurance Company of the State of Pennsylvania, the Ninth Circuit recently addressed the issue of whether general liability policies issued in the 1960s and 1970s included aggregate limits for claims arising under the premises-operations coverage in CGL policies. The difference between the policyholder’s interpretation of the policies’ limits clauses and the insurer’s interpretation was worth hundreds of millions of dollars in exposure for the insurer. The Court closely examined the policy language and extrinsic evidence from both the insurance industry’s drafting history and the parties before concluding that the policies were ambiguous. The Court construed that ambiguity in favor of the policyholder and ruled that aggregate limits did not apply to the claims at issue. The Court’s decision underscores the importance of carefully examining a policy’s limits, especially for older policies written before 1986 when the insurance industry revised the standard-form CGL policy to state the aggregate limits apply not only to products liability claims but to premises-operations claims as well. Decades of insurance industry drafting history confirms, as the policyholder’s submissions in this case indicate, that the industry well understood that operations claims like the environmental waste-disposal claims at issue here typically were not subject to aggregate limits. 

The California Supreme Court ruled that vertical exhaustion applied to determine how a policyholder could access its excess insurance policies. Montrose Chem. Corp. v. Superior Court, No. S244737 (Cal. Apr. 6, 2020). The case involved coverage for Montrose Chemical Corporation’s environmental liabilities at its Torrance facility under insurance policies issued from 1961 to 1985. Montrose and its insurers agreed that Montrose’s primary policies were exhausted but disputed the sequence in which Montrose could access the excess insurance policies.
