Instructions for Certifying Your Tax Status With BNY Mellon

Certify Your Tax Status

This certification requirement applies to U.S. citizens and those holding U.S. Resident status. In addition, if you are a foreign citizen and you do not have a U.S. Tax ID, you must still certify your country of residence. It is your responsibility to confirm that your tax status has been updated in BNY Mellon's system.

You must certify the Tax ID for each Equity Holdings account that you control. For example, if you own SAIC stock in a personal account and also in a trust, you must certify the Tax ID for both of these accounts separately even if the Tax ID is the same. In addition, you must certify the Tax ID for your ESPP account unless your prior certification in your Equity Holdings account has been transferred to your ESPP account.

To certify the Tax ID for your account or confirm that you have already certified it, follow these steps:

1. Have Your Access ID and Password/PIN Ready

   If you don't have your Access ID or Password/PIN, you may obtain either by calling the phone numbers below and waiting through the prompts until you reach a customer service representative. If BNY Mellon does not have an e-mail address for your account, your access information will be sent through regular mail.

It is your responsibility to confirm that your tax status has been updated in BNY Mellon's system.
