Note 2 — Earnings Per Share
Basic earnings per share (“EPS”) is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options, stock awards, and shared performance stock awards.
The components of basic and diluted EPS are as follows:
| (In millions, except earnings per share) | |||||
| Year Ended June 30, | 2013 | 2012 | 2011 | ||
| Net income available for common shareholders (A) | $ 21,863 | $ 16,978 | $ 23,150 | ||
| Weighted average outstanding shares of common stock (B) | 8,375 | 8,396 | 8,490 | ||
| Dilutive effect of stock-based awards | 95 | 110 | 103 | ||
| Common stock and common stock equivalents (C) | 8,470 | 8,506 | 8,593 | ||
| Earnings Per Share | |||||
| Basic (A/B) | $ 2.61 | $ 2.02 | $ 2.73 | ||
| Diluted (A/C) | $ 2.58 | $ 2.00 | $ 2.69 | ||
Anti-dilutive stock-based awards excluded from the calculations of diluted EPS were immaterial during the periods presented.
