The weighted average numbers of shares outstanding listed in the table below were anti-dilutive and excluded from the computation of diluted income (loss) per share. In the case of restricted stock units, this is because unrecognized compensation expense exceeds the current value of the awards (i.e., grant date market value was higher than current average market price). In the case of stock options, this is because the average market price did not exceed the exercise price. These shares may be dilutive potential common shares in the future (in thousands):
