A.M. Best Co. has upgraded the financial strength rating (FSR) to A (Excellent) from A- (Excellent) and issuer credit ratings (ICR) to “a” from “a-” of AmTrust Group (AmTrust) (New York, NY) and its property/casualty members, which operate through an intercompany quota share reinsurance arrangement with AmTrust International Insurance, Ltd. (AII) (Hamilton, Bermuda). Concurrently, A.M. Best has upgraded the FSR to A (Excellent) from A- (Excellent) and ICR to “a” from “a-” of IGI Insurance Company Ltd. (IGI) (United Kingdom). Additionally, A.M. Best has upgraded the ICR to “bbb” from “bbb-” of the parent holding company, AmTrust Financial Services, Inc. (AFSI) (headquartered in New York, NY) (NASDAQ: AFSI). The outlook for all ratings has been revised to stable from positive. (See below for a detailed list of the companies.) The rating actions reflect AmTrust’s solid balance sheet strength, sustained strong operating performance within its niche market segments and the benefits derived from AFSI, including AFSI’s commitment to maintain sufficient capital as well as to provide access to additional capital should it be needed to support the group’s expanding operations. AmTrust has been successful in executing its business plan, which is focused on growth through acquisition of renewal rights offerings and established books of business at appropriate rates, terms and conditions, further benefitting from its expandable underwriting platform that generates significant expense savings. Partially offsetting these positive factors are the group’s continued growth in both premium volume and associated liabilities in recent years, primarily achieved through renewal rights transactions, and the inherent risk associated with integrating new business. Despite these concerns, the outlook recognizes AmTrust’s strong sustained operating results within its market segments, its ongoing access to capital and commitment to prudent underwriting through its proven business platform. The rating actions on IGI acknowledge the company’s strong risk-adjusted capitalization, solid underwriting and operating performance within its niche market segments and the implicit and explicit support provided by ASFI, including financial flexibility and reinsurance support afforded through an intercompany quota share agreement with AII.
