OLDWICK, N.J.–(BUSINESS WIRE)– AM Best has affirmed the Financial Strength Rating of A+ (Superior) and the Long-Term Issuer Credit Ratings of "aa-" (Superior) of Central States Indemnity Co. of Omaha (CSI), and its subsidiary, CSI Life Insurance Company (CSI Life). The outlook of the Credit Ratings (ratings) is stable. Both companies are domiciled in Omaha, NE. The ratings reflect CSI and CSI Life's balance sheet strengths, which AM Best assesses as strongest, as well as their adequate operating performances, limited business profiles and appropriate enterprise risk managements. Additionally, CSI and CSI Life benefit from their very conservative underwriting leverages, strong liquidity positions and the implicit support from their ultimate parent, Berkshire Hathaway Inc. (Berkshire) [NYSE: BRK A and BRK B].
