Income Per Common Share
Income Per Common Share
Basic income per common share amounts are calculated using the weighted-average number of common shares outstanding for the period. Diluted income per common share amounts are calculated using the weighted-average number of common shares outstanding for the period and include the dilutive impact of exercise of stock options as well as assumed lapse of restrictions on restricted stock awards and shares currently available for purchase under the Company's Employee Stock Purchase Plan, using the treasury stock method. Performance-based restricted stock units are considered contingently issuable shares for diluted income per common share purposes and the dilutive impact, if any, is not included in the weighted-average shares until the performance conditions are met.
The two-class method is used to calculate basic and diluted income per common share for the applicable periods since certain of the Company's restricted stock were participating securities. The two-class method is an earnings allocation formula that determines income per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Under the two-class method, basic income per common share is computed by dividing net income attributable to common shares after allocation of income to participating securities by the weighted-average number of common shares outstanding during the year. Diluted income per common share is computed using the more dilutive of the two-class method or the if-converted method. In periods of net loss, no effect is given to participating securities since they do not contractually participate in the losses of the Company. The two-class method is the more dilutive method for fiscal 2014. As of January 31, 2015, the Company no longer has any outstanding participating securities.
The following table reconciles net income and the weighted average common shares outstanding used in the computations of basic and diluted income per common share (in thousands, except for share and per share data):

For fiscal 2014, $20.0 thousand of net income was attributable to participating securities, as the two-class method was more dilutive, and the remainder was attributable to common shareholders.
The effects of the assumed exercise of stock options outstanding as of January 28, 2017, January 30, 2016 and January 31, 2015 for 164,440, 710,153 and 593,773 shares of common stock, respectively, were excluded from the fiscal 2016, fiscal 2015 and fiscal 2014 calculation of diluted income per common share as their impact would have been anti-dilutive.
The effects of non-vested restricted stock units outstanding as of January 28, 2017, January 30, 2016 and January 31, 2015 for 3,600, 6,500 and 3,930 shares of common stock, respectively, were excluded from the fiscal 2016, fiscal 2015 and fiscal 2014 calculation of diluted income per common share as their impact would have been anti-dilutive.
The aforementioned excluded shares do not reflect the impact of any incremental repurchases under the treasury stock method.
