Potentially dilutive instruments include stock options, convertible preferred stock and senior unsecured convertible notes. At July 31, 2013 and 2012, there were options to purchase 3.2 million and 3.2 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 and refer to Footnote 9 for information on the senior unsecured convertible notes.
