Basic EPS$2.73 $2.74 
Diluted EPS$2.73 $2.74 
(a)Our unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.
(b)The dilutive effect of unexercised stock options excludes from the computation of EPS 0.1 million and 0.3 million of options for the three months ended March 31, 2022 and 2021, respectively, because inclusion of the options would have been anti-dilutive.
