AM Best has maintained the under review with negative implications status for the Financial Strength Rating of A- (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of "a-" (Excellent) of Watford Re Ltd. (Watford Re) (Bermuda) and its subsidiaries, Watford Insurance Company Europe Limited (WICE) (Gibraltar), Watford Insurance Company (WIC) (New Jersey) and Watford Specialty Insurance Company (WSIC) (New Jersey). In addition, AM Best has maintained the under review with negative implications status for the Long-Term ICR of "bbb-" (Good) and the Long-Term Issue Credit Rating of "bb" (Fair) on the $225 million ($52 million outstanding) 8.5% cumulative preference shares of Watford Holdings Ltd. (Watford) (Bermuda) (NASDAQ:WTRE), the group's ultimate holding company.

This Credit Rating (rating) action considers the recent announcement that Arch Capital Group Ltd. (Arch) has completed its merger agreement with Watford. Arch has assigned its interests and obligations under the merger agreement to a newly formed entity, Greysbridge Holdings Ltd., under which Arch owns approximately a 40% stake, with funds managed by Warburg Pincus LLC and Kelso & Company, each owning approximately 30%.

AM Best acknowledges that the transaction with Arch could benefit the Watford group through potential further de-risking of its investment portfolio, removing the burden of public company status, and possible rating enhancement stemming from being a member of a large, well-diversified group. However, although the transaction has closed, the ultimate impact to Watford's ratings will be determined when AM Best has met with management and analyzed the group's business plans, including an analysis of future investment risk, financial projections and operating structure within the Arch group. The under review status therefore is expected to be resolved following these discussions. AM Best will continue to evaluate Watford's balance sheet strength, operating performance and enterprise risk management to assess that it stays in line with projected amounts.
