The Company computes net loss per share of Class A common stock and Class B common stock using the two-class method required for participating securities. The earnings per share amounts are the same for the different classes of common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or liquidation. The calculation of basic and diluted earnings per common share is as follows (in thousands, except per share amounts):
