Instructions for Certifying Your Tax Status With Computershare

IRS regulations require that you certify your tax identification number (for most personal accounts, this means certifying your social security number) on your Equity Holdings and/or ESPP account(s) with Computershare Shareowner Services prior to the payment of any dividend or sale of stock through Computershare.


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 Computershare'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 Employee Grants and Awards account if you are going to submit a cashless hold option exercise. You must also certify the Tax ID for your ESPP account unless your prior certification in your Equity Holdings account has been transferred to your ESPP account.

You may be entitled to receive some amount of this withholding tax back from the IRS depending on your personal tax circumstances, but the additional withholding of shares can not be reversed by Computershare.
