Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings per share (EPS) amounts are computed by dividing earnings, after the deduction of preferred stock dividends declared, by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. The information used to compute basic and diluted EPS attributable to Arconic common shareholders was as follows (shares in millions):

Net income | $ | 187 |  |  | $ | 143 |
Less: preferred stock dividends declared | (1 | ) |  | (1 | )
Net income available to Arconic common shareholders - basic | 186 |  |  | 142 |

Net income available to Arconic common shareholders - diluted | $ | 190 |  |  | $ | 145 |

Common stock outstanding at March 31, 2019 and 2018 was 453 and 483, respectively. The decrease in common stock outstanding at March 31, 2019 was due to the impact of share repurchases of approximately 32 in the first quarter of 2019 (see Note H). As average shares outstanding are used in the calculation for both basic and diluted EPS, the full impact of share repurchases was not realized in the first quarter of 2019 EPS as the share repurchases occurred midway through the quarter on February 21, 2019. The following shares were excluded from the calculation of average shares outstanding – diluted as their effect was anti-dilutive (shares in millions).
