Pfizer has a tool to determine the cost-basis for your Pfizer stock. To learn more please visit our cost-basis calculator tool.

Book-entry form of registered ownership allows you to own shares without having paper stock certificates in your possession. You are the record owner and enjoy the same shareholder benefits as you would with certificated shares.

Book-entry ownership eliminates some of the problems associated with paper certificates such as storage and safety of securities. Book-entry shares also eliminate the requirement for physical movement of stock certificates at the time of sale or transfer of ownership.

If you hold your book-entry shares through the Shareholder Investment Program you will receive a statement at the end of every month in which an investment or other stock activity takes place. If you have book-entry shares but do not participate in the Shareholder Investment Program, you will receive a statement of your holdings on a yearly basis. You may, of course, request an additional statement at any time by contacting Computershare.

Yes. Simply send your certificates to Computershare with written instructions to deposit them in your account as book-entry items. Do not endorse the certificates or complete the assignment section. We recommend that you send your certificates by certified or registered mail and insure them for 3% of the market value of the stock.

You may request stock certificates for the whole shares in your book-entry account at any time. Simply contact Computershare with your request and a stock certificate for the requested number of whole shares will be sent to you within 7-10 business days.

As a Pfizer shareholder of record, you have the option of depositing your dividends electronically into your bank or other financial institution on each dividend payment date through the Direct Deposit of Dividends Service.

With direct deposit, your dividend funds are available to you on the dividend payment date. This means no waiting for checks to come in the mail, no trips to the bank to make deposits, and no waiting for the checks to clear.

Instead of a check, you will receive a dividend payment statement from Pfizer. This statement will advise you of the amount of the dividend deposited, where it was deposited and the date of deposit. Of course, your bank statement will also reflect the electronic deposit.

The Direct Deposit of Dividends Service is available to you if your shares of Pfizer common stock are held in your own name. If your shares are held through a broker, you must first have the shares transferred into your own name in order to be eligible for the Pfizer Direct Deposit of Dividends Service.

You must complete and sign the Authorization Form and send it to:
Pfizer Inc.
c/o Computershare
College Station, TX 77842-3170

If you change banks or accounts, you must notify Computershare of the change and include your new bank account number. If you decide not to participate in direct deposit any longer, you must notify Computershare of that decision. We will gladly make any change as soon as we are notified.
