A.M. Best has removed from under review with positive implications and upgraded the Financial Strength Rating to A- (Excellent) from B++ (Good) and the Long-Term Issuer Credit Rating to "a-" from "bbb+" of Great Plains Casualty Inc. (Great Plains) (Cedar Rapids, IA). The outlook assigned to these Credit Ratings (ratings) is stable.

The ratings of Great Plains were placed under review on Oct. 13, 2017 in conjunction with the release of the updated Best's Credit Rating Methodology (BCRM). The ratings have been removed from under review, as A.M. Best has completed its analysis of Great Plains under the updated BCRM.

The ratings reflect Great Plains' balance sheet strength, which A.M. Best categorizes as very strong, based on its limited size, as well as its strong operating performance, limited business profile and appropriate enterprise risk management (ERM).
