Earnings Per Share [Abstract] |
Net Income Per Share | Note 4: Net Income Per Share Basic per share amounts are computed using the weighted-average number of common shares outstanding during the period. Diluted per share amounts are calculated using the weighted-average number of common shares outstanding during the period and, when dilutive, the weighted-average number of potential common shares from the issuance of common stock to satisfy outstanding restricted stock units and the exercise of outstanding options to purchase common stock using the treasury stock method. The following schedule reconciles the shares used to calculate basic and diluted net income per share:
|  | Three Months Ended |  |  | Nine Months Ended |
(In thousands) |  | October 1, 2021 |  |  | October 2, 2020 |  |  | October 1, 2021 |  |  | October 2, 2020 |
Shares used in basic per share computation |  |  | 52,618 |  |  |  | 52,316 |  |  |  | 52,597 |  |  |  | 52,383 |
Effect of dilutive common stock options outstanding |  |  | 245 |  |  |  | 331 |  |  |  | 239 |  |  |  | 351 |
Effect of dilutive restricted stock units outstanding |  |  | 449 |  |  |  | 562 |  |  |  | 480 |  |  |  | 608 |
Shares used in diluted per share computation |  |  | 53,312 |  |  |  | 53,209 |  |  |  | 53,316 |  |  |  | 53,342 |
Common stock options to purchase 0 and 40,000 shares were excluded from the diluted per share calculation for the three months ended October 1, 2021 and October 2, 2020, respectively, due to their anti-dilutive effect. Common stock options to purchase 0 and 34,139 shares were excluded from the diluted per share calculation for the nine months ended October 1, 2021 and October 2, 2020, respectively, due to their anti-dilutive effect.
