Earnings Per Share [Abstract]

Earnings per Share

Earnings per Share

We compute our basic earnings per share based on the weighted-average number of common shares outstanding and our diluted earnings per share based on the weighted-average number of common shares outstanding adjusted by the number of additional shares that would have been outstanding had potentially dilutive common shares been issued. Potentially dilutive securities include stock options, nonvested share awards and shares issuable under our employee stock purchase plan. Nonvested market-based share awards and nonvested performance-based share awards are included in the average diluted shares outstanding for each period if established market or performance criteria have been met at the end of the respective periods.

The following table presents a reconciliation of the numerators and denominators of basic and diluted earnings per share from continuing operations attributable to Best Buy Co., Inc. ($ and shares in millions):

	Three Months Ended
	May 4, 2013		May 5, 2012
Numerator
Net earnings from continuing operations attributable to Best Buy Co., Inc. shareholders	$	97	$	169
Denominator
Weighted-average common shares outstanding	339.0		342.2
Effect of potentially dilutive securities:
Nonvested share awards	2.0		0.6
Weighted-average common shares outstanding, assuming dilution	341.0		342.8
Net earnings per share from continuing operations attributable to Best Buy Co., Inc.
Basic	$	0.29	$	0.49
Diluted	$	0.29	$	0.49

The computation of weighted-average common shares outstanding, assuming dilution, excluded options to purchase 25.1 million and 31.7 million shares of our common stock for the three months ended May 4, 2013 and May 5, 2012, respectively. These amounts were excluded as the options’ exercise prices were greater than the average market price of our common stock for the periods presented and, therefore, the effect would be anti-dilutive (i.e., including such options would result in higher earnings per share).
