For the three and nine months ended September 30, 2018, the diluted earnings per share was calculated using net income available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period, determined using the treasury stock method. For the three and nine months ended September 30, 2017, diluted loss per share was calculated using basic common shares outstanding, as inclusion of potentially dilutive common shares would be anti-dilutive.

Performance-based employee compensation awards are considered potentially dilutive in the initial period in which the performance conditions are met.

The following awards were excluded from the computation of diluted earnings (loss) per share:
