## Dividends 

Alcoa’s objective is to pay common stock dividends at rates competitive with other investments of equal risk and consistent with the need to reinvest earnings for long-term growth. To support this objective, Alcoa pays a quarterly dividend of 15 cents per common share and 93.75 cents per preferred share. Quarterly dividends are paid to shareowners of record at each quarterly distribution date. 

## Dividend Reinvestment 

The company offers a Dividend Reinvestment and Stock Purchase Plan for shareowners of Alcoa common and preferred stock. The plan allows shareowners to reinvest all or part of their quarterly dividends in shares of Alcoa common stock. Shareowners also may purchase additional shares under the plan with cash contributions. The company pays brokerage commissions and fees on these stock purchases. 

## Direct Deposit of Dividends 

Shareowners may have their quarterly dividends deposited directly to their checking, savings, or money market accounts at any financial institution that participates in the Automated Clearing House (ACH) system.
