 7. Per Share Data and Stockholders’ Equity 
 
 The calculation of diluted earnings per share considers the
 potential dilutive effect of options and shares under Sonic’s
 stock compensation plans. Certain of Sonic’s non-vested
 restricted stock and restricted stock units contain rights to
 receive non-forfeitable dividends and , as a result, are considered
 participating securities and are included in the two-class method
 of computing earnings per share. The following table illustrates
 the dilutive effect of such items on earnings per share for the
 second quarter and six-month periods ended June 30, 2014 and
 2013:

 In addition to the stock options included in the table above,
 options to purchase approximately 0.4 million shares and
 0.9 million shares of Class A Common Stock were
 outstanding at June 30, 2014 and 2013, respectively, but were
 not included in the computation of diluted earnings per share
 because the options were not dilutive.
