Earnings Per Share [Abstract] |
Earnings (Loss) Per Share | Earnings (Loss) Per Share The reconciliation of basic and diluted earnings per share for each period presented was as follows (dollars and shares in thousands, except per share amounts):
| Year ended December 31,
| 2022 |  | 2021
Net income (loss) attributable to common stockholders | $ | 3,712 |  |  | $ | (82,651) |
Basic - weighted average shares outstanding | 5,747 |  |  | 5,643 |
Dilutive effect of stock options and restricted stock | 204 |  |  | — |
Dilutive effect of convertible 2025 Notes | — |  |  | — |
Diluted - weighted average shares outstanding | 5,951 |  |  | 5,643 |
Earnings (loss) per share |  |  |
Basic | $ | 0.65 |  |  | $ | (14.65) |
Diluted | $ | 0.62 |  |  | $ | (14.65) |
The diluted earnings per share calculation excludes approximately 84 thousand shares for 2022 because they were anti-dilutive. For the year ended December 31, 2022, we excluded the assumed conversion of the 2025 Notes in calculating diluted earnings per share as the effect was anti-dilutive. For the year ended December 31, 2021, we excluded all potentially dilutive restricted shares, stock options and the assumed conversion of the 2025 Notes in calculating diluted earnings per share as the effect was anti-dilutive due to net losses incurred for the period.
