(1) | Diluted loss per share was computed without consideration to potentially dilutive instruments as their inclusion would have been antidilutive, as the strike prices are above current market price. Potentially dilutive instruments include stock options and convertible preferred stock. At January 31, 2013 and 2012, there were options to purchase 3.1 million and 3.0 million shares of common stock, respectively. Refer to our Annual Report on Form 10-K for the year ended October 31, 2012 for information on our convertible preferred stock.
