Earnings Per Share [Abstract] |
Earnings Per Share | 17 - Earnings Per Share We have two classes of common stock, which we refer to as Class A common stock and Class B common stock. Our Class A common stock is entitled to be paid cash dividends that are at least 10% higher than the cash dividends we pay on our Class B common stock. Accordingly, we use the two-class method for the computation of earnings per common share. The two-class method is an earnings allocation formula that determines earnings per share separately for each class of common stock based on dividends declared and an allocation of remaining undistributed earnings using a participation percentage reflecting the dividend rights of each class. We present below a reconciliation of the numerators and denominators we used in the basic and diluted per share computations for our Class A common stock:

We used the following information in the basic and diluted per share computations for our Class B common stock:
|  | Year Ended December 31, |
(in thousands, except per share amounts) |  | 2019 |  |  | 2018 |  |  | 2017 |
Basic and diluted earnings (loss) per share: |  |  |  |  |  |  |  |  |  |  |  |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Allocation of net income (loss) |  | $ | 8,434 |  |  | $ | (6,069 | ) |  | $ | 1,237 |
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Weighted-average shares outstanding |  |  | 5,577 |  |  |  | 5,577 |  |  |  | 5,577 |
Basic and diluted earnings (loss) per share |  | $ | 1.51 |  |  | $ | (1.09 | ) |  | $ | 0.22 |
During 2019, we did not include options to purchase 5,531,561 shares of our Class A common stock in the computation of diluted earnings per share because the exercise price of the options was greater than the average market price of our Class A common stock.
