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 and deferred stock awards and the assumed conversion of our convertible senior notes, where dilutive. For the three months ended March 31, 2020 and 2019, there were no reconciling items to the weighted average common shares outstanding in the calculation of diluted net income (loss) per common share.
The following table shows securities excluded from the calculation of diluted net income (loss) per common share because such securities are anti-dilutive:
