On January 31, 2018, USG’s Board of Directors raised the total authorization under USG’s share repurchase program to $500 million.  As of December 31, 2017, $66 million remained under USG’s previously authorized $250 million share repurchase program. USG intends to execute the share repurchases over the next eighteen months.  Under the program, USG may repurchase shares from time to time in open market or privately negotiated transactions, subject to market conditions and in accordance with applicable securities laws. There is no guarantee as to the exact number of shares or value that will be repurchased under the stock repurchase program and USG may discontinue purchases at any time. Whether USG makes any repurchases will depend on many factors, including but not limited to its business and financial performance, the business and market conditions at the time, including the price of USG shares, and other factors that management considers relevant. Repurchases are expected to be made from available cash on hand.
