Earnings Per Share [Abstract] |
Net Income Per Share | Note 3: Net Income Per Share The following table reconciles the shares used in the calculation of basic net income per share to those used for diluted net income per share:
(in millions) | 2016 |  | 2015 |  | 2014
Net income | $ | 143.6 |  |  | $ | 95.6 |  |  | $ | 127.1 |
Weighted average common shares outstanding | 73.3 |  |  | 72.0 |  |  | 70.9 |
Dilutive effect of stock options, stock appreciation rights and performance share awards, based on the treasury stock method | 1.7 |  |  | 1.8 |  |  | 1.9 |
Weighted average shares assuming dilution | 75.0 |  |  | 73.8 |  |  | 72.8 |
During 2016, 2015 and 2014, there were 0.1 million, 0.7 million, and 0.5 million shares from stock-based compensation plans not included in the computation of diluted net income per share because their impact was antidilutive. In December 2015, we announced a share repurchase program authorizing the repurchase of up to 700,000 shares of our common stock from time to time on the open market or in privately-negotiated transactions as permitted under the Securities Exchange Act of 1934 Rule 10b-18. During 2016, we purchased 700,000 shares of our common stock under this program at a cost of $52.2 million, or an average price of $74.54 per share. This share repurchase program expired on December 31, 2016. In December 2016, we announced a share repurchase program authorizing the repurchase of up to 800,000 shares of our common stock from time to time on the open market or in privately-negotiated transactions as permitted under the Securities Exchange Act of 1934 Rule 10b-18. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions. This share repurchase program commenced on January 1, 2017 and is expected to be completed by December 31, 2017.
