For the three months ended September 30, 2014, the computation of diluted net income per share included 5 thousand shares of unvested restricted common stock and options to purchase approximately $0.8 million shares that had a dilutive effect of 297 thousand shares. For the nine months ended September 30, 2014, the computation of diluted net income per share included 5 thousand shares of unvested restricted common stock and options to purchase approximately $0.8 million shares that had a dilutive effect of 299 thousand shares. Options to purchase 345 thousand shares were not included in the computation of diluted net income per share for the three and nine months ended September 30, 2014, as their exercise prices were in excess of the average stock prices for the periods.

For the three months ended September 30, 2013, the computation of diluted net income per share included 23 thousand shares of unvested restricted common stock and options to purchase approximately 0.8 million shares that had a dilutive effect of 196 thousand shares. For the nine months ended September 30, 2013, the computation of diluted net income per share included 23 thousand shares of unvested restricted common stock. Options to purchase 440 thousand and 1.3 million shares were not included in the computation of diluted net income per share for the three and nine months ended September 30, 2013, respectively, as their exercise prices were in excess of the average stock prices for the periods.
