Item 8.01 Other Events

On January 28, 2010, Highbury Financial Inc. (“Highbury”) announced today that as of January 25, 2010, it had 18,526,171 shares of common stock outstanding. In addition, there are 4,500,000 shares of common stock reserved for issuance upon conversion of Highbury’s 1,000 outstanding shares of Series B Convertible Preferred Stock (“Preferred Stock”). Highbury has agreed with each holder of Preferred Stock that prior to the effective time of the proposed merger (“Merger”) of Higbhury into a wholly owned subsidiary of Affiliated Managers Group, Inc., a Delaware corporation publicly traded on the New York Stock Exchange (“AMG”), the Preferred Stock will be exchanged for newly issued shares of Highbury common stock. All of Highbury’s warrants to purchase shares of common stock that were not exercised prior to 5:00pm ET on January 25, 2010 have expired.

On January 25, 2010, after taking into account the proceeds received upon the exercise of warrants, Highbury had cash and cash equivalents and investments of approximately $30.0 million and no debt outstanding. Immediately prior to the closing of the Merger, subject to applicable law and the terms of the merger agreement by which the Merger will be effectuated, the board of directors of Highbury is permitted to declare a special cash dividend, payable upon the closing of the Merger, to all shareholders of record of Highbury common stock immediately prior to the effective time of the Merger (including the holders of shares of Highbury common stock issued in exchange for shares of Preferred Stock) in an aggregate amount equal to Highbury’s working capital (including all Highbury liabilities then outstanding, subject to certain exceptions, and merger related transaction expenses then outstanding) less $5,000,000. In addition to the $30 million of cash and cash equivalents and investments as of January 25, 2010, there are other factors that may affect the amount of the special dividend, including the existing liabilities of Highbury, future liabilities of Highbury, interim dividends paid to Highbury shareholders, and the results of operations of Highbury between now and the closing of the Merger. In addition, because the Merger is subject to a number of conditions, some of which are beyond the control of AMG and Highbury, including approval of the Merger by Highbury shareholders, the exact timing for completion of the Merger cannot be predicted with certainty. Accordingly, the amount of the cash and cash equivalents and investments as of January 25, 2010, should not be equated with the amount of the anticipated special dividend.

A copy of the Press Release issued by Highbury on January 28, 2010 is incorporated by reference herein and attached hereto as Exhibit 99.1.
