Earnings Per Share [Abstract] |
Net Income per Share | Net Income per Share Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock awards, convertible senior notes and warrants issued by the Company. The dilutive effect of outstanding stock awards is reflected in diluted earnings per share by application of the treasury stock method and the dilutive effect of the convertible securities is reflected in diluted earnings per share by application of the if-converted method. The components used in the computation of basic and diluted net income per share for the years ended December 31, 2024, 2023 and 2022 were as follows (in thousands, except per share data):

For the years ended December 31, 2024, 2023 and 2022, certain potential outstanding shares from service-based stock awards and warrants were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain market- and performance-based stock awards were excluded from the computation of diluted net income per share because the underlying market and performance conditions for such stock awards had not been met as of these dates. The number of potentially outstanding shares excluded from the computation of diluted net income per share for the years ended December 31, 2024, 2023 and 2022 were as follows (in thousands):
| 2024 |  | 2023 |  | 2022
