In addition, in connection with one of the Company’s investments in a non-U.S. alternative Affiliate accounted for under the equity method, the Company entered into an arrangement with a minority owner of the Affiliate that gives such owner the right to elect to sell a portion of its 19% ownership interest in the Affiliate to the Company annually. The purchase price of these conditional purchases will be at fair market value. During the three months ended December 31, 2018, the Company was notified by the minority owner that it may, after determining the fair market value of its interest, elect to sell a 5% ownership interest in the Affiliate to the Company. If the minority owner elects to sell this interest, the transaction is expected to be completed during the first half of 2019; however, the Company cannot currently predict the amount that may be paid to settle this commitment. If the Company acquires the minority owner’s interest over time, it will continue to account for the Affiliate under the equity method. The Company and certain of its consolidated Affiliates operate under regulatory authorities that require the maintenance of minimum financial or capital requirements. Management is not aware of any significant violations of such requirements.
