EPS
Basic$1.90  $1.50  
Diluted$1.89  $1.49  

Shares underlying stock options excluded from first quarter 2020 and 2019 calculations of diluted EPS were 3,921,686 and 2,261,873, respectively, because the grant price of these options was greater than the average market price of the Company's common stock and the effect of including them in the calculation of diluted EPS would have been antidilutive. First quarter 2020 and 2019 reflects share repurchases of 510,301 and 1,582,076, respectively.

The Company declared cash dividends of $0.66 and $0.62 per share in first quarter 2020 and 2019, respectively.
