Shares of common stock of approximately 0.2 million and 0.2 million at June 30, 2018 and 2017, respectively, that are issuable through the exercise of dilutive securities were not included in the computation of diluted net income per share because their effect would have been antidilutive. In connection with the issuance of the 1.625% Convertible Senior Notes due in 2016, which the Company extinguished on December 15, 2016, the Company entered into call transactions and warrant transactions with the affiliates of the initial purchasers of such notes. The warrants expired on a series of expiration dates from March 2017 to August 2017. For the year ended December 31, 2017, the hedge participants exercised 8,707,202 warrants. As a result, the Company issued 2,839,743 shares of common stock for the year ended December 31, 2017. The company has no outstanding warrants as of June 30, 2018. For the three and six months ended June 30, 2017, the potential excess conversion value on warrants was included in the Company's dilutive share calculation because the average stock price for the three and six months ended June 30, 2017 exceeded the conversion price. Restricted and performance units that entitle the holders to approximately 0.5 million shares of common stock are included in the basic and diluted weighted average shares outstanding calculation because no further consideration is due related to the issuance of the underlying common shares.
