Earnings per Share

Basic earnings per share ("EPS") is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period, excluding dilution for potential common stock issuances. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, including: (1) shares issuable upon the vesting of RSUs and common stock option exercises using the treasury stock method; and (2) shares issuable upon the conversion of the Company's MCPS, as determined under the if-converted method. For purposes of calculating diluted EPS, preferred stock dividends have been subtracted from net income (loss) in periods in which utilizing the if-converted method would be anti-dilutive.

The computation of basic and diluted EPS is as follows:

The following table details the securities that have been excluded from the above computation of weighted-average number of shares for diluted EPS, because the effect would be anti-dilutive.
