NOTE 2. EARNINGS PER SHARE

Basic earnings per common share excludes potentially dilutive securities and is computed by dividing Net earningsattributable to Viacom by the weighted average number of common shares outstanding during the period. The determination of diluted earnings per common share includes the potential dilutive effect of equity-based compensation awards based upon the application of the treasury stock method. Anti-dilutive common shares are excluded from the calculation of diluted earnings per common share.

The following table sets forth the computation of the common shares outstanding used in determining basic and diluted earnings per common share and anti-dilutive shares:
