Computation of Net Earnings per Share |
Computation of Net Earnings per Share | Note 7. Computation of Net Earnings per Share ​ Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted-average number of shares of common stock outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased by the number of additional shares of common stock that would have been outstanding if the potentially dilutive shares of common stock issuable on exercise of stock options and vesting of RSUs had been issued, calculated using the treasury stock method. ​ The components of net earnings per share are as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three months ended | ​ | Nine months ended | ​
​ | ​ | September 30, | ​ | September 30, | ​
​ |  | 2024 |  | 2023 |  | 2024 |  | 2023 |
​ | ​ | (in thousands, except per share amounts) | ​
Net income available to common stockholders | ​ | $ | 48,576 | ​ | $ | 65,931 | ​ | $ | 151,036 | ​ | $ | 175,207 | ​
Weighted average shares of common stock outstanding used in computing basic income per share | ​ |  | 32,550 | ​ |  | 32,807 | ​ |  | 32,595 | ​ |  | 32,775 | ​
Incremental options and RSUs | ​ |  | 125 | ​ |  | 352 | ​ |  | 185 | ​ |  | 433 | ​
Weighted average shares of common stock used in computing diluted net income per share | ​ |  | 32,675 | ​ |  | 33,159 | ​ |  | 32,780 | ​ |  | 33,208 | ​
Net income per share | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Basic | ​ | $ | 1.49 | ​ | $ | 2.01 | ​ | $ | 4.63 | ​ | $ | 5.35 | ​
Diluted | ​ | $ | 1.49 | ​ | $ | 1.99 | ​ | $ | 4.61 | ​ | $ | 5.28 | ​
​ ​ Diluted weighted average shares of common stock outstanding does not include 109,266 and 734 common equivalent shares issuable with respect to outstanding equity awards for the three-month periods ended September 30, 2024 and 2023, respectively, or 21,477 and 2,598 common equivalent shares issuable with respect to outstanding equity awards for the nine-month periods ended September 30, 2024 and 2023, respectively, as their effect would have been anti-dilutive.
