EARNINGS PER COMMON SHARE

Net income allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividends from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the SARs to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 14. Basic earnings per common share (EPS) is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units. Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock.

Computations for basic and diluted EPS are provided below.
