On June 12, 2017, we approved the election of Vishnu Srinivasan as a director to fill the vacancy on our Board of Directors, to be effective upon the commencement of trading of our Class A common stock on the NASDAQ Capital Market. Upon his election to the Board of Directors, Mr. Srinivasan will serve on our audit and risk committee, our nominating and corporate governance committee and our compensation committee. This action was taken by means of an action by unanimous written consent of our Board of Directors in lieu of a special meeting.

Mr. Srinivasan, age 38, agreed to become a director and join our board of directors, effective as of the commencement of trading of our Class A common stock on NASDAQ. Mr. Srinivasan joined Ganesh Investments, L.L.C. in November 2012 and is a Director focused on public and private equity investments. Ganesh Investments provides investment advisory services to members of the Pritzker family and their charitable foundations. Previously, Mr. Srinivasan was an Analyst at Alyeska Investment Group, a long/short hedge fund, from November 2009 to October 2012, and a Principal at Berkshire Partners, a private equity fund, where he held various roles from August 2002 until October 2009. Mr. Srinivasan graduated summa cum laude from the Wharton School at the University of Pennsylvania with a B.S. in Economics. Mr. Srinivasan also received an MBA from Harvard Business School. Our board of directors has determined that Mr. Srinivasan’s 13 years’ experience in public and private equity, investment and management services qualifies him to be a member of the board of directors in light of the Company’s business and structure.
