[1] Diluted loss per share was computed without consideration to potentially dilutive instruments as their inclusion would have been antidilutive. Potentially dilutive instruments include stock options and convertible preferred stock. At April 30, 2013 and 2012, there were options to purchase 3.2 million and 3.3 million, respectively, shares of common stock. Refer to our Annual Report on Form 10-K for the year ended October 31, 2012 for information on our convertible preferred stock.
