Class of Stock Disclosures [Abstract] |
Common Stock Repurchase Program | Common Stock Repurchase Program Autodesk has a stock repurchase program that is used to offset dilution from the issuance of stock under the Company’s employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders. Stock repurchases have the effect of returning excess cash generated from the Company’s business to stockholders. During the three and six months ended July 31, 2017, Autodesk repurchased and retired 1.2 million and 3.4 million shares at an average repurchase price of $102.71 and $91.33 per share, respectively. Common stock and additional paid-in capital and accumulated deficit were reduced by $20.8 million and $97.8 million, respectively, during the three months ended July 31, 2017. Common stock and additional paid-in capital and accumulated deficit were reduced by $82.0 million and $228.6 million, respectively, during the six months ended July 31, 2017. At July 31, 2017, 23.2 million shares remained available for repurchase under the repurchase program approved by the Board of Directors. During the six months ended July 31, 2017, Autodesk repurchased its common stock through open market purchases. The number of shares acquired and the timing of the purchases are based on several factors, including general market and economic conditions, the number of employee stock option exercises and stock issuances, the trading price of Autodesk common stock, cash on hand and available in the United States, cash requirements for acquisitions, and Company defined trading windows.
