For the respective years ended August 31, 2016 and 2015, stock options to purchase 9,354 and 20,271 shares of common stock were outstanding, but were not included in the calculation of diluted net income per share because their inclusion would be antidilutive. No stock options were excluded from the calculation for the year ended August 31, 2017. Included in the calculation of dilutive common stock equivalents are the unvested portion of restricted stock and stock options.
