The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. The Company’s participating securities are its grants of restricted stock which contain non-forfeitable rights to dividends. The Company allocates earnings between both classes; however, in periods of undistributed losses, they are only allocated to common shares as the unvested restricted stockholders do not contractually participate in losses of the Company. The Company computes basic earnings per share by dividing net income allocated to common shareholders by the weighted average number of shares outstanding during the period. Warrants issued in connection with the Company's long-term debt were issued at a nominal exercise price and are considered outstanding at the date of issuance. Diluted earnings per share is calculated to give effect to all potentially dilutive common shares that were outstanding during the period. Weighted average diluted common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock options and the assumed vesting of nonvested share awards.
