Earnings Per Share [Abstract] |
Earnings Per Share | Note 10—Earnings Per Share Basic earnings per share is computed by dividing net income available to each class of shares by the weighted-average number of shares of common stock outstanding and participating securities during the period. Participating securities include the Company’s series A, B and C preferred stock and restricted stock units (“RSUs”) that contain non-forfeitable rights to dividends or dividend equivalents. Net income is allocated to each class of common stock and participating securities based on its proportional ownership on an as-converted basis. The weighted-average number of shares outstanding of each class of common stock reflects changes in ownership over the periods presented. See Note 9—Stockholders’ Equity. Diluted earnings per share is computed by dividing net income available by the weighted-average number of shares of common stock outstanding, participating securities and, if dilutive, potential class A common stock equivalent shares outstanding during the period. Dilutive class A common stock equivalents may consist of: (1) shares of class A common stock issuable upon the conversion of series A, B and C preferred stock and class B and C common stock based on the conversion rates in effect through the period, and (2) incremental shares of class A common stock calculated by applying the treasury stock method to the assumed exercise of employee stock options, the assumed purchase of stock under the Company’s Employee Stock Purchase Plan and the assumed vesting of unearned performance shares.
