Earnings (Loss) Per Share [Abstract] |
Earnings Per Share | Note 15—Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increases is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following:
| Three Months Ended March 31, |
| 2023 |  |  | 2022 |
| (in thousands) |
Basic weighted-average number of shares |  | 25,326 |  |  |  | 25,764 |
Effect of dilutive securities: |  |  |  |  |  |  |
Stock options and warrants |  | 805 |  |  |  | 308 |
Non-vested restricted Class B common stock |  | 441 |  |  |  | 56 |
Unissued vested deferred stock units |  | 48 |  |  |  | — |
Diluted weighted-average number of shares |  | 26,620 |  |  |  | 26,128 |
Unissued vested deferred stock units in three months ended March 31, 2023 pertain to the weighted average of restricted shares of the company's Class B common stock that the Company expects to issue related to satisfaction of 2022 market conditions (see Note 12 — Equity). The following shares were excluded from the diluted earnings per share computations:
| Three Months Ended March 31, |
| 2023 |  |  | 2022 |
| (in thousands) |
Shares underlying options and warrants |  | — |  |  |  | 126 |
Non-vested deferred stock units |  | — |  |  |  | 580 |
Stock options were excluded from the diluted earnings per share computation for the three months ended March 31, 2022 because the exercise prices of the stock options were greater than the average market prices of the Company's stock during the period. Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market conditions for vesting of those deferred stock units were not met as of March 31, 2022.
