During the three months ended June 30, 2019 and 2018, we issued 44,514 and 72,777 shares of common stock, respectively. During the six months ended June 30, 2019 and 2018, we issued 145,461 and 170,930 shares of common stock, respectively. These shares were issued primarily upon: (a) the satisfaction of required conditions under certain of our share-based compensation plans and (b) the purchase of common stock pursuant to our employee stock purchase plan.

On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. On December 5, 2013, October 23, 2014, October 28, 2015, October 25, 2017 and October 23, 2018, our Board of Directors authorized us to repurchase up to an additional $100.0 million, $250.0 million, $200.0 million, $100.0 million and $200.0 million of our outstanding common stock, respectively. No shares of our common stock were repurchased during the six months ended June 30, 2019. Since the inception of the repurchase programs through June 30, 2019, we have repurchased approximately 15.9 million shares of our common stock for approximately $791.5 million. As of June 30, 2019, there remained authorization for us to repurchase approximately $158.5 million of our shares. The repurchase programs have no expiration date and do not obligate the Company to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. We may repurchase our shares from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our 2016 Credit Agreement, placing limitations on such repurchases. The repurchase programs have been and will be funded from our operations.
