13. HUNTSMAN CORPORATION STOCKHOLDERS’ EQUITY

Share Repurchase Program

On February 7, 2018 and on May 3, 2018, our Board of Directors authorized us to repurchase up to an additional $950 million in shares of our common stock in addition to the $50 million remaining under our September 2015 share repurchase authorization. The share repurchase program will be supported by our free cash flow generation. Repurchases may be made through the open market, including through accelerated share repurchase programs, or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. During the three months ended March  31, 2019, we repurchased 1,525,767 shares of our common stock for approximately $34 million, excluding commissions, under the repurchase program, of which approximately $1 million was settled in April 2019.  From April 1, 2019 through April 22, 2019, we repurchased an additional 316,958 shares of our common stock for approximately $8 million, excluding commissions.

Dividends on Common Stock

During each of the quarters ended March 31, 2019 and March 31, 2018 we paid dividends of $39 million, or $0.1625 per share, to common stockholders.
