NOTE 14 — EARNINGS PER SHARE

Basic earnings per share is based on the weighted-average effect of all common shares issued and outstanding and is calculated by dividing net income by the weighted-average shares outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted-average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. Dell excludes equity instruments from the calculation of diluted earnings per share if the effect of including such instruments is anti-dilutive. Accordingly, certain stock-based incentive awards have been excluded from the calculation of diluted earnings per share totaling 137 million and 158 million common shares for the third quarters of Fiscal 2012 and Fiscal 2011, respectively, and 147 million and 188 million for the nine months ended October 28, 2011, and October 29, 2010, respectively.
The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended October 28, 2011, and October 29, 2010:
