Best Company on Friday to assign a financial strength rating of 'A' (Excellent) to Catlin Insurance Company Inc. and upgrade the financial strength rating of Catlin Specialty Insurance Company Inc to 'A' (Excellent) from 'A-'. Both companies are part of Catlin US, the Catlin Group's US-based underwriting platform. Stephen Catlin, chief executive of Catlin Group Limited, said: 'I am delighted that the two Catlin US insurance companies have received 'A' financial strength ratings from A.M. Best. The ratings demonstrate the excellent financial security that Catlin US and the rest of the Catlin Group offer to our clients worldwide. A.M. Best's affirmation of the companies' financial strength is a key step in the continuing development of Catlin US.' In its announcement, A.M. Best said the ratings 'reflect the solid risk-adjusted capitalization of both companies,' although A.M. Best also noted that the outlook for the ratings is negative due to the current negative outlook assigned to Catlin Insurance Company Ltd. of Bermuda (Catlin Bermuda), the parent of both US insurers. - ends - For more information contact: Media Relations: James Burcke, Tel: +44 (0)20 7458 5710 Head of Communications, London Mobile: +44 (0)7958 767 738 E-mail: james.burcke@catlin.com Liz Morley, Maitland Tel: +44 (0)20 7379 5151 E-mail: emorley@maitland.co.uk Investor Relations: William Spurgin, Tel: +44 (0)20 7458 5726 Head of Investor Relations, London Mobile: +44 (0)7710 314 365 E-mail: william.spurgin@catlin.com Notes to editors: 1.
