Earnings Per Share
Basic net income (loss) per common share is computed by dividing the net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. The calculation of diluted net income (loss) per common share includes the effects of the assumed exercise of any outstanding stock options, the assumed vesting of shares of restricted stock and the assumed conversion of our convertible senior notes, where dilutive.
The following table sets forth the computation of weighted average common shares outstanding:
