Earnings Per Share [Abstract]  
Net Income (Loss) Per Share Net Income (Loss) Per Share

The Company computes net income (loss) per share using the two-class method required for multiple classes of common stock and participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are substantially identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock share equally in the Company’s net income and losses.

Basic net income (loss) per share is computed by dividing net income attributable to common shareholders by the weighted-average number of shares of the Class A and Class B common stock outstanding.

Diluted net income (loss) per share is computed by dividing net income attributable to common shareholders by the weighted-average number of diluted common shares outstanding. The computation of the diluted net income (loss) per share of Class A common stock assumes the conversion of our Class B common stock to Class A common stock, while the diluted net income (loss per share) of Class B common stock does not assume the conversion of those shares to Class A common stock.

The numerators and denominators of the basic and diluted EPS computations for our common stock are calculated as follows (in millions, except for per share amounts):
