Earnings Per Share [Text Block] | Note 13 – Net Income (Loss) Per-Share Basic and diluted income (loss) per share are based on the weighted average number of shares of common stock and potential common stock outstanding during the period. Potential common stock, for the purpose of determining diluted income per share, includes the effects of dilutive unvested restricted stock, options to purchase common stock and convertible securities. The effect of such potential common stock is computed using the treasury stock method or the if-converted method, as applicable. The following table presents a reconciliation of the numerators and denominators of the basic and diluted income (loss) per share computations for income from continuing operations. In the table below, income (loss) represents the numerator and shares represent the denominator (in thousands except per share amounts):
