Earnings Per Share [Abstract] |
Net Income Per Share | Net Income Per Share Basic net income per share is calculated as net income divided by the weighted average number of shares outstanding. Diluted net income per share is calculated as net income divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. The Corporation’s common stock equivalents consist of outstanding stock options, restricted stock, restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). PSUs are required to be included in weighted average shares outstanding if performance measures, as defined in each PSU award agreement, are met as of the end of the period. A reconciliation of weighted average shares outstanding used to calculate basic net income per share and diluted net income per share follows:
| Three months ended September 30 |  | Nine months ended September 30
| 2016 |  | 2015 |  | 2016 |  | 2015
| (in thousands)
Weighted average shares outstanding (basic) | 173,020 |  |  | 174,338 |  |  | 173,248 |  |  | 176,399 |
Impact of common stock equivalents | 1,044 |  |  | 1,004 |  |  | 1,017 |  |  | 1,029 |
Weighted average shares outstanding (diluted) | 174,064 |  |  | 175,342 |  |  | 174,265 |  |  | 177,428 |
For the three and nine months ended September 30, 2016, 447,000 and 712,000 stock options, respectively, were excluded from the diluted net income per share computation as their effect would have been anti-dilutive. For the three and nine months ended September 30, 2015, 1.5 million and 1.8 million stock options, respectively, were excluded from the diluted net income per share computation as their effect would have been anti-dilutive.
