Travelers Casualty and Surety Company, Formerly Known as Aetna Casualty and Surety Company v. Certain Underwriters…

Summary

The New York Court of Appeals affirmed the Appellate Division’s summary‑judgment rulings, holding that Travelers could not aggregate the numerous environmental loss settlements at Koppers and DuPont as a single “disaster and/or casualty” under the excess‑of‑loss reinsurance treaties. The court also rejected Travelers’ reliance on the “follow the fortunes” clauses, finding they do not override the explicit treaty language.
