Numerator
Earnings attributable to Eastman, net of tax $134 $235 
Denominator
Weighted average shares used for basic EPS118.9129.0

EPS
Basic$1.13 $1.82 
Diluted$1.12 $1.80 

Shares underlying stock options of 1,879,459 and 507,692 for first quarter 2023 and 2022, respectively, were excluded from calculations of diluted EPS because the grant date exercise 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. The Company did not repurchase shares in first quarter 2023. First quarter 2022 reflects 548,035 shares delivered as part of the accelerated share repurchase program the Company entered into in fourth quarter 2021 (the "2021 ASR").

The Company declared cash dividends of $0.79 and $0.76 per share for first quarter 2023 and 2022, respectively.
