The vesting of certain of our employee-related restricted stock units is contingent upon the satisfaction of predefined performance measures. The shares underlying these equity awards are included in the weighted-average dilutive common shares only if the performance measures are met as of the end of the reporting period. Additionally, potential common shares are not included in the denominator of the diluted earnings per common share calculation when the inclusion of such shares would be anti-dilutive.

Weighted-average shares excluded from the computation of diluted earnings per share were as follows (amounts in millions):
