For the three months ended September 30, 2011 and 2010, options to purchase 0.1 million and 0.2 million shares of common stock, respectively, were outstanding, but not included in the computation of diluted net income per share because the exercise price exceeded the value of the shares and the effect would have been anti–dilutive. For the nine months ended September 30, 2011 and 2010, options to purchase 0.1 million and 0.2 million shares of common stock, respectively, were outstanding, but not included in the computation of diluted net income per share because the effect would have been anti–dilutive. For the three months ended September 30, 2011 and 2010, restricted stock units (“RSUs”) of 1.1 million and 1.3 million, respectively, and for the nine months ended September 30, 2011 and 2010, RSUs of 0.6 million and 1.2 million, respectively, were outstanding, but not included in the computation of diluted net income per share because the effect would have been anti-dilutive.
