12.	Earnings Per Share

ASC 260, Earnings Per Share (ASC 260), requires dual presentation of basic and diluted earnings per share on the face of the income statement. Basic earnings per share excludes dilution and is computed by dividing income by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive. Using the treasury stock method, diluted earnings per share include the incremental effect of RSUs that are no longer subject to a market or performance condition. The chart below shows the calculation of basic and diluted earnings per share (in thousands, except per share amounts):
