A.M. Best Assigns Ratings to Swiss Re Corporate Solutions Ltd.

A.M. Best Co. has assigned a financial strength rating of A+ (Superior) and an issuer credit rating of "aa-" to Swiss Re Corporate Solutions Ltd. (SRCSL) (Switzerland). The outlook assigned to both ratings is stable.

The ratings of SRCSL are based on its strong expected risk-based capitalization, profitable projected operating results and worldwide scope of operations. SRCSL is the top level operating and holding company of Swiss Re Group's Corporate Solutions business segment, which provides property, casualty and special lines insurance to commercial businesses. Swiss Re Group had been writing these lines of business through existing legal entities for many years, with a geographic focus on North America, Europe and Asia.

Initially, SRCSL's role will be to aggregate risk from its affiliated companies by providing various forms of internal and external reinsurance protection. The company will not initially write external business.

A.M. Best expects SRCSL to maintain risk-based capitalization that will be fully supportive of its rating level and produce operating results in line with projections. The company's risk management is fully integrated with Swiss Re Group's formal risk management program that oversees all aspects of SRCSL's individual risks.

The methodology used in determining these ratings is Best's Credit Rating Methodology, which provides a comprehensive explanation of A.M. Best's rating process and contains the different rating criteria employed in the rating process. Key criteria utilized include: "Risk Management and the Rating Process for Insurance Companies"; "Understanding BCAR for Property/Casualty Insurers"; "Catastrophe Analysis in A.M. Best Ratings"; and "Rating Members of Insurance Groups." Best's Credit Rating Methodology can be found at www.ambest.com/ratings/methodology.
