Shares of common stock of approximately 0.3 million and 0.4 million at September 30, 2017 and 2016, 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.

For the three and nine months ended September 30, 2017 and 2016 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 nine months ended September 30, 2017 and 2016 exceeded the conversion price.

For the three and nine months ended September 30, 2016 the potential excess conversion value on the 2016 Notes were included in the Company's dilutive share calculation because the average stock price for the three and nine months ended September 30, 2016 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.
