The computation of dilutive shares from stock-based compensation does not include 0.6 million shares and 0.9 million shares for the three months ended September 30, 2014 and 2013, respectively, and 0.6 million shares and 1.4 million shares for the nine months ended September 30, 2014 and 2013, respectively, as their effect would have been anti-dilutive.
