(4) EARNINGS PER SHARE

Basic earnings per share represent net earnings divided by the weighted average number of common shares outstanding for the period. Diluted earnings per share, in addition to the weighted average determined for basic earnings per share, includes potential common shares, if dilutive, which would arise from the exercise of stock options and nonvested shares using the treasury stock method.

The Company has two classes of issued and outstanding common stock, Class A Common Stock and Class B Common Stock. Holders of Class A Common Stock and holders of Class B Common Stock have substantially identical rights, including rights with respect to any declared dividends or distributions of cash or property and the right to receive proceeds on liquidation or dissolution of the Company after payment of the Company’s indebtedness. The two classes have different voting rights, with holders of Class A Common Stock entitled to one vote per share while holders of Class B Common Stock are entitled to ten votes per share. The Company uses the two-class method for calculating net earnings per share. Basic and diluted net earnings per share of Class A Common Stock and Class B Common Stock are identical.
