Earnings Per Share [Abstract] |
Earnings Per Share | Note 13: Earnings Per Share The shares used in the computation of the company’s basic and diluted earnings per common share are as follows:
|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 28, |  |  | September 29, |  |  | September 28, |  |  | September 29, |
|  | 2013 |  |  | 2012 |  |  | 2013 |  |  | 2012 |
Weighted-average common shares outstanding |  |  | 58,163,261 |  |  |  | 58,257,569 |  |  |  | 58,221,047 |  |  |  | 58,195,162 |
Dilutive effect of stock-based instruments |  |  | 837,840 |  |  |  | 600,067 |  |  |  | 848,938 |  |  |  | 619,474 |
Weighted-average common shares outstanding, assuming dilution |  |  | 59,001,101 |  |  |  | 58,857,636 |  |  |  | 59,069,985 |  |  |  | 58,814,636 |
The dilutive effect of the potential exercise of outstanding stock-based instruments to purchase common shares is calculated using the treasury stock method. There were no options outstanding that were anti-dilutive for the three and nine month periods ended September 28, 2013, and for the three month period ended September 29, 2012. Options to purchase 395,524 shares of Snap-on common stock for the nine month period ended September 29, 2012, were not included in the computation of diluted earnings per share as the exercise price of the options was greater than the average market price of the common stock for the respective period and the effect on earnings per share would be anti-dilutive.
