See “Note 1 - Acquisitions” for additional discussion of the Vitruvian Acquisition. Stock Repurchase Program In January 2018, the board of directors of the Company approved a stock repurchase program to acquire up to $100 million of the Company's outstanding stock during 2018. Purchases under the repurchase program may be made from time to time in open market or privately negotiated transactions, and are subject to market conditions, applicable legal requirements, contractual obligations, and other factors. The repurchase program does not require the Company to acquire any specific number of shares. This repurchase program is authorized to extend through December 31, 2018 and may be suspended from time to time, modified, extended, or discontinued by the board of directors at any time. During the three months ended March 31, 2018, the Company repurchased 9.7 million shares for a total cost of approximately $100.0 million. All repurchased shares have been retired.
