Atlantic Power Corporation Announces August 2012 Common Share Dividend

BOSTON, Aug. 15, 2012 /PRNewswire/ -- Atlantic Power Corporation (TSX: ATP) (NYSE: AT) (the "Company") today announced its distribution for the month of August 2012.  A dividend of Cdn$0.09583 per common share will be payable on September 28, 2012 to holders of record at the close of business on August 31, 2012.

Dividend Reinvestment Plan

On August 8, 2012, Atlantic Power announced the details of the Company's Dividend Reinvestment Plan ("DRIP" or the "Plan"). The DRIP allows eligible holders of Common Shares to reinvest their cash dividends (if, as and when declared by the Company's board of directors and paid) to acquire additional Common Shares of Atlantic Power at a 3% discount to market price, as defined in the Plan.

All holders of Common Shares who are Canadian or U.S. residents are eligible to participate in the Plan.  Shareholders who wish to participate in the DRIP should contact their brokerage firm to enroll in the Plan. 

A complete copy of the DRIP and enrollment information is available in the "Investors" section of the Company's website www.atlanticpower.com or here. Shareholders are urged to carefully read the complete Plan before making any decisions regarding their participation in the DRIP.

Participation in the DRIP does not relieve shareholders of any liability for taxes that may be payable in respect of dividends that are reinvested in new Common Shares pursuant to the DRIP. Eligible shareholders interested in participating in the DRIP should consult their own tax advisors concerning the tax implications and consequences of their participation in the DRIP in their particular circumstances.

This news release does not constitute an offer to sell or the solicitation of an offer to buy securities in any jurisdiction.

Tax Information for Shareholders

Atlantic Power Corporation designates its 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.
