Fireman’s Fund Insurance Co. sued OneBeacon Insurance Co. for breach of a facultative reinsurance certificate. Fireman’s Fund settled claims with its insured and allocated a portion of the settlement to a Fireman’s Fund excess policy reinsured by OneBeacon. OneBeacon denied Fireman’s Fund’s claim, arguing that its reinsurance obligations did not attach until all insurance underlying the Fireman’s Fund policy were exhausted in payment of the full limits of the underlying policies. The Fireman’s Fund policy stated that it applies “only after all underlying insurance has been exhausted,” but did not define “exhaustion.” The reinsurance certificate provided that OneBeacon’s liability shall follow Fireman’s Fund’s, that the terms of the certificate shall be subject “in all respects” to the Fireman’s Fund policy, except as stated in the certificate, and that “all claims involving this reinsurance, when settled by [Fireman’s Fund], shall be binding on [OneBeacon].”

On cross-motions for summary judgment, the court agreed with Fireman’s Fund that the term “exhaustion” was ambiguous as used in the Fireman’s Fund policy, as the policy did not specify whether the full limits of underlying insurance must actually be paid before the Fireman’s Fund policy attaches. Applying Second Circuit precedent established in Zeig v. Massachusetts Bonding Co., 23 F.2d 665 (2d Cir. 1928), the court held that once the underlying insurer settled and discharged the claims against the insured, Fireman’s Fund was within its right to treat the underlying limits as “exhausted,” even though the underlying insurer did not actually pay the full limits of its policy. In addition, based on the follow-the-fortunes and follow-the-settlements doctrines, the court found it was barred from second-guessing Fireman’s Fund’s post-settlement allocation decisions. The court therefore granted Fireman’s Fund’s motion for summary judgment and denied OneBeacon’s cross-motion.
