Earnings Per Share

NOTE 10.         Earnings Per Share

Basic earnings per share were computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during each period. Shares issued or reacquired during the period, if applicable, were weighted for the portion of the period that they were outstanding. Diluted earnings per share give effect to potentially dilutive securities, including convertible preferred stock and equity compensation awards.

The following table sets forth the computation of basic and diluted net income per common share (in millions, except per share amounts):
