A.M. Best assigns ‘excellent’ ratings for Split Rock
A.M. Best has assigned a financial strength rating of “A (Excellent)” and a long-term issuer credit rating of “a” to Split Rock Insurance, located in Bermuda.
Split Rock, the wholly-owned subsidiary of OneBeacon Insurance Group, was established in 2013 to reinsurance its affiliate Atlantic Specialty Insurance Company (ASIC), also a subsidiary of OneBeacon.
OneBeacon’s ultimate parent is White Mountains Insurance Group.
The ratings of ASIC have been extended to Split Rock “due to the implicit and explicit support it receives as a result of its affiliation with ASIC and OneBeacon”.
