DIVIDEND WITHHOLDING TAX INFORMATION

Notice to all Non-Canadian Resident Shareholders

In 2012, the Canada Revenue Agency (CRA) changed how the tax withholding rate applied to dividend payments made to non-residents is determined. The CRA now requires a certification of residency from each shareholder so that the preferred tax treaty rate can be applied where applicable to persons resident in countries which have a tax treaty with Canada.

Form NR301 will be mailed to all Registered non-resident shareholders by Computershare Investor Services Inc. In order to receive the preferred treaty rate, you must complete and mail back the form as soon as possible. Failure to supply a completed NR301 form will result in Computershare withholding the statutory 25% withholding tax rate on any payments to Registered non-resident shareholders. You can also download the form here. Instructions on how to correctly complete the NR301 are on the back of the form. Shareholders who hold their shares through a broker should contact their broker directly. They do not need to return a form to Computershare. Shareholders who have already completed Form NR301 do not need to complete a new form.

Shareholders who hold their shares through a nominee should contact their nominee.
