A total of 32,398,023 shares of Company common stock, par value $0.01 per share, were registered for issuance in connection with the Company’s acquisition of B/E Aerospace, Inc., a Delaware corporation (“B/E Aerospace”), which was completed on April 13, 2017, by means of the merger of Quarterback Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of the Company, with and into B/E Aerospace, with B/E Aerospace continuing as the surviving corporation and a wholly owned subsidiary of the Company (the “B/E Acquisition”).
