A.M. Best Co. has affirmed the financial strength rating of A (Excellent) and issuer credit rating of “a” of Seven Seas Insurance Company, Inc. (Seven Seas) (Riviera Beach, FL). The outlook for both ratings is stable. The ratings reflect Seven Seas’ sustained underwriting and operating profitability, excellent capitalization and the synergies gained from its effective low-cost distribution platform and preferential access to those it insures via the customer network of its affiliate, Tropical Shipping. Tropical Shipping is one of the largest transporters of containerized cargo from the United States and Canada to the Caribbean region and the Bahamas. The ratings also acknowledge management’s specialty underwriting expertise within the ocean and inland marine cargo market as well as its strong client relationships, effective loss control and risk management techniques. Seven Seas and Tropical Shipping are both ultimately owned by AGL Resources, Inc. (AGL) (NYSE: GAS) following AGL’s merger with Nicor Inc., effective December 9, 2011. AGL, an Atlanta-based energy services holding company, is one of the nation’s largest natural gas distribution companies.
