[1] | On December 1, 2015, the Company completed its acquisition of Legacy Hay, a global leader in people strategy and organizational performance, for $476.9 million, net of cash acquired. The purchase price consisted of $259.0 million in cash ($54 million from foreign locations), net of estimated cash acquired and 5,922,136 shares of the Company's common stock, par value $0.01 per share (the "Consideration Shares"), representing an aggregate value of $217.9 million based on the closing price of the Company's common stock on The New York Stock Exchange on November 30, 2015. On November 23, 2015, the Company borrowed $150 million from the Term Facility, to finance a portion of the Legacy Hay acquisition purchase price. As part of the acquisition, the Company has committed to a $40 million retention pool (of which $14.5 million and $9.0 million were paid in fiscal 2018 and 2017, respectively) for certain employees of Legacy Hay subject to certain circumstances. The remaining balance will be payable within 45 days after November 30, 2018.
