Basic income or loss per common share are determined by dividing net income or loss applicable to common stock by the weighted average number of common shares actually outstanding during the year. Diluted income or loss per common share is based on the increased number of shares that would be outstanding assuming conversion of dilutive outstanding securities using the “as if converted” method. The following table sets forth the computation of basic and diluted loss per share (in thousands, except share data):
