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, as well as common shares that would have resulted from the assumed conversion of our convertible debentures. Since the potentially dilutive shares related to the convertible debentures are included in the computation, the related interest expense, net of tax, is added back to net earnings, as the interest would not have been paid if the convertible debentures had been converted to common stock. In February 2012, we repurchased and redeemed all of the remaining outstanding convertible debentures. 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 attributable to Best Buy Co., Inc. (shares in millions):

The computation of weighted-average common shares outstanding, assuming dilution, excluded options to purchase 30.7 million and 34.1 million shares of our common stock for the three months ended November 3, 2012 and October 29, 2011, respectively, and options to purchase 28.6 million and 30.2 million shares of our common stock for the nine months ended November 3, 2012 and October 29, 2011, 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).
