Share Repurchase Programs

In June 2015, our board of directors authorized us to repurchase up to $500 million of our Class A common stock in open market purchases or through privately negotiated transactions in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the Exchange Act), subject to market conditions, applicable legal requirements and other relevant factors. The repurchase program does not obligate IHS to repurchase any set dollar amount or number of shares and is scheduled to expire on November 30, 2017, but may be suspended at any time at our discretion. The amount authorized under this program is inclusive of share repurchases of our Class A common stock surrendered by employees in an amount equal to the statutory tax liability associated with the vesting of their equity awards, for which we pay the statutory tax on behalf of the employee. During the six months ended May 31, 2016, we repurchased 648,854 shares on the open market under this program for a total of approximately $75.0 million, at an average price of approximately $115.58 per share. Since inception of the program, we have repurchased a total of 1,879,641 shares for approximately $216.7 million, at an average price of approximately $115.29 per share.
