AVERAGE SHARES OUTSTANDING

Our basic earnings per share calculation is computed based on the weighted-average number of common shares outstanding. Our diluted earnings per share calculation is computed based on the weighted-average number of common shares outstanding adjusted by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued. Potentially dilutive common shares include stock options, nonvested stock awards and units, and non-management director stock equivalents. Performance share awards are included in the average diluted shares outstanding each period if the performance criteria have been met at the end of the respective periods.

The following table reconciles basic weighted-average shares outstanding to diluted weighted-average shares outstanding (in thousands):
