Earnings Per Share [Abstract]  
Schedule of Earnings Per Share, Basic and Diluted
Per Share
 
Basic loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted loss per share is calculated by dividing net loss by the weighted average shares outstanding assuming dilution. Dilutive common shares outstanding is computed using the Treasury Stock Method and reflects the additional shares that would be outstanding if dilutive stock options were exercised and restricted stock and restricted stock units were settled for common shares during the period. In addition, dilutive shares include any shares issuable related to PSUs for which the performance conditions have been met as of the end of the period.

There were no dilutive effects during the three and six months ended June 30, 2019 and 2018 as a result of a net loss incurred in each period. The number of antidilutive securities excluded from the computation of diluted earnings per share amounts was not material. The computations of basic and diluted loss per share for the three and six months ended June 30, 2019 and 2018 are as follows (in thousands, except per share amounts):
