AM Best Co. has affirmed the financial strength rating of A- (excellent) and issuer credit ratings of “a-” of Maiden Insurance Company Ltd (MIC), Maiden Reinsurance Company (MRC) and its wholly-owned subsidiary, Maiden Specialty Insurance Company (MSIC), all of which operate through an intercompany quota share reinsurance agreement.Concurrently, Best has affirmed the ICR of “bbb-” of the parent holding company, Maiden Holdings Ltd.The outlook for all ratings is stable.Best said that the ratings of the group reflected its solid risk-adjusted capitalisation achieved through capital contributions from Maiden Holdings and the operational benefits that MIC derives as a quota share partner with AmTrust Financial Services Inc’s (AFSI) Bermuda reinsurance subsidiary, AmTrust International Insurance Ltd (AII) and American Capital Acquisition Corporation (ACAC). In addition, the ratings reflected MRC and MSIC’s strategic importance to Maiden Holdings as a dedicated US reinsurance platform providing treaty, accident and health and specialty facultative reinsurance.Partially offsetting these positive rating factors is the execution risk faced by the group’s management in achieving its business plans and integrating newer business, said the ratings agency. Despite these concerns, MIC’s outlook is supported by the financial commitment of Maiden Holdings, its seasoned management team and the dedicated distribution MIC, MRC and MSIC shares with AFSI and ACAC.
