Atlantic Power Corporation Announces February 2012 Common Share Dividend

BOSTON, Feb. 15, 2012 /CNW/ - Atlantic Power Corporation (TSX: ATP) (NYSE: AT) (the "Company") today announced its distribution for the month of February 2012. A dividend of Cdn$0.09583 per common share will be payable on March 30, 2012 to holders of record at the close of business on February 29, 2012.

Tax Information for Shareholders
Atlantic Power Corporation designates this dividend to be an "eligible dividend" pursuant to subsection 89(14) of the Income Tax Act (Canada) and its equivalent in any provinces of Canada.

U.S. individual or other non-corporate taxpayers should be eligible for the reduced rate of tax currently applicable to "qualified dividends" provided that the investor meets the holding period and any other requirements.

The Company's common share dividend is subject to a 25% withholding tax rate for holders that are not residents of Canada, which may be reduced pursuant to an applicable tax treaty. The withholding tax rate is 15% for U.S.-resident holders that qualify for the benefits of the Canada – U.S. Income Tax Convention.

Non-Canadian holders may be required by their brokers to complete a Form NR301 (or an equivalent form) in order to demonstrate their entitlement to a treaty-reduced rate of withholding tax after December 31, 2012. U.S. and other non-Canadian holders should consult their brokers about the requirement to provide such forms.

U.S. individuals holding shares in taxable accounts may be eligible to receive a credit on their U.S. income tax return for this withholding tax. U.S. individuals holding the Company's common shares in Individual Retirement Accounts ("IRAs") may be exempt from withholding tax pursuant to the Canada – U.S. Income Tax Convention.

Taxpayers should always seek their own independent qualified professionals regarding the tax consequences of purchasing or owning common shares of the Company. Individuals who believe the withholding tax exemption applies to their IRA should contact their broker to determine how to claim the exemption.
