The Company’s Board of Directors has also appointed Mr. Bilden to serve on its Compensation Committee and Finance Committee, effective immediately.

Mr. Bilden retired in June 2016 as a co-founding member of the private equity firm HarbourVest Partners, a leading global private equity investment management firm with institutional assets under management in excess of $42 billion. He began his career in Boston in 1991 and relocated to Hong Kong in 1996 to establish the firm’s Asian subsidiary. Mr. Bilden was responsible for the firm’s investment strategy and execution, capital-raising and client service activities throughout the Asia Pacific region, managing personnel and partnerships in multiple countries and cultures. Throughout his 25-year tenure at HarbourVest Partners, he served in senior leadership roles in the firm’s global management, including the firm’s six-person executive committee responsible for governance.

Mr. Bilden currently serves on the Chief of Naval Operations Executive Panel; the Board of Directors of the United States Naval Academy Foundation; and the Board of Trustees and Executive Committee as Vice Chairman of the Naval War College Foundation. He is also serving as the inaugural Chairman of the Center for Cyber Conflict Studies Task Force at the Naval War College Foundation and serves on the Advisory Board of Contrast Capital Management, LLC.
