Plaintiff, a reinsurer, and defendant, a holding company of several primary insurers, were parties to reinsurance agreements covering certain liabilities of the defendant’s member companies. In 2004, the parties entered into a commutation agreement. The agreement required the plaintiff to make a payment of $15,248,338 to the defendant “in full satisfaction of the Reinsurer’s past, present and future net liability” under the reinsurance agreements. Thereafter, the defendant continued to pay premiums under one set of the reinsurance agreements, and the plaintiff continued to make claims payments to the defendant under those agreements, despite the commutation. The plaintiff discovered its error in 2008, stopped claims payments and refused further premium. However, the defendant took the position that the commutation did not cover the agreements under which it continued to pay premiums and under which plaintiff had continued to pay claims. The plaintiff filed suit seeking a declaration that the subject agreements were covered by the commutation, and seeking recoupment of the approximately $500,000 in claims payments it believed it made in error from 2004 to 2008. The trial court granted judgment to the plaintiff, including the monetary relief, and the defendant appealed, arguing that the commutation agreement was ambiguous. The Connecticut Appellate Court disagreed, affirming the verdict in favor of the plaintiff. , No. AC 33388 (Conn. App. Ct. Oct. 23, 2012).
