A.M. Best Co. has assigned a debt rating of “bb” to the forthcoming issuance of $150 million 7.25% mandatory convertible preferred stock due September 2016 to be issued by Maiden Holdings Ltd. (Maiden) (Hamilton, Bermuda) (NASDAQ: MHLD). The outlook assigned is stable. All remaining ratings of Maiden and its subsidiaries are unchanged. (For further information, please see A.M. Best’s press release dated May 24, 2013.) The proceeds from the issuance will be used in the continued support and development of Maiden’s reinsurance business and for other general corporate purposes. With the issuance of these preferred shares, Maiden’s unadjusted debt-to-total capital and adjusted debt-to-tangible capital are 45% and 27%, respectively.
