Due to the net loss to common shareholders in each of the years presented above, diluted earnings per share was computed without consideration to potentially dilutive instruments as their inclusion would have been antidilutive. Potentially dilutive instruments include stock options, warrants, unvested RSAs and RSUs and convertible preferred stock. At October 31, 2015, 2014 and 2013, there were options to purchase 0.3 million shares of common stock. At October 31, 2015, 2014 and 2013, respectively, there were warrants to purchase 0.2 million, 0.5 million and 0.4 million shares of common stock, which were not included in the calculation of diluted earnings per share as they would be antidiulutive.
