Earnings Per Share [Abstract]

EARNINGS PER SHARE

13. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding stock options, restricted stock-based awards and shares issuable under the employee stock purchase plan using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended August 31,
(in millions, except per share data)	2012		2011
Net income	$	2,034	$	1,840
Weighted average common shares outstanding		4,867		5,062
Dilutive effect of employee stock plans		72		88
Dilutive weighted average common shares outstanding		4,939		5,150
Basic earnings per share	$	0.42	$	0.36
Diluted earnings per share	$	0.41	$	0.36
Shares subject to anti-dilutive stock options and restricted stock-based awards excluded from calculation(1)		188		85

(1) These weighted shares relate to anti-dilutive stock options and restricted stock-based awards as calculated using the treasury stock method (described above) and could be dilutive in the future.
