Earnings Per Share [Abstract] |
EARNINGS AND DIVIDENDS PER SHARE | EARNINGS AND DIVIDENDS PER SHARE The following table sets forth the computation of basic and diluted earnings per share ("EPS") which are calculated using the treasury stock method:
| First Quarter |  |
(In millions, except per share amounts) | 2021 |  | 2020 |  |  |  |
Numerator |  |  |  |  |  |  |
Earnings attributable to Eastman, net of tax | $ | 274 |  |  | $ | 258 |  |  |  |  |
Denominator |  |  |  |  |  |  |
Weighted average shares used for basic EPS | 136.1 |  | 136.0 |  |  |  |
Dilutive effect of stock options and other awards | 1.5 |  | 0.5 |  |  |  |
Weighted average shares used for diluted EPS | 137.6 |  | 136.5 |  |  |  |
(Calculated using whole dollars and shares) |  |  |  |  |  |  |
EPS |  |  |  |  |  |  |
Basic | $ | 2.01 |  |  | $ | 1.90 |  |  |  |  |
Diluted | $ | 1.99 |  |  | $ | 1.89 |  |  |  |  |
Shares underlying stock options excluded from first quarter 2021 and 2020 calculations of diluted EPS were 327,782 and 3,921,686, respectively, 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. First quarter 2021 and 2020 reflect share repurchases of 354,795 and 510,301, respectively. The Company declared cash dividends of $0.69 and $0.66 per share for first quarter 2021 and 2020, respectively.
