Earnings Per Share

6 Months Ended

Jun. 30, 2015

The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. Service-based and performance-based restricted stock granted by the Company is considered a participating security as these awards contain a non-forfeitable right to dividends.

The following table sets forth the computation of earnings per share for the three and six months ended June 30, 2015 and 2014 (in millions, except per share amounts):

The Company did not have any significant anti-dilutive securities during the three and six months ended June 30, 2015 and 2014. The calculation of diluted earnings per share for the three and six months ended June 30, 2015 excludes 28,096 and 28,403, respectively, of performance shares granted in December 2014 that are subject to a performance condition. Those shares are excluded from the calculation of diluted earnings per share for the three and six months ended June 30, 2015 because all necessary performance conditions were not satisfied at the end of those reporting periods.
