Macquarie Power and Infrastructure Corporation Provides Tax Information for U.S. Shareholders

TORONTO, ONTARIO--(Marketwire - April 5, 2011) - Macquarie Power and Infrastructure Corporation (TSX:MPT)(TSX:MPT.DB.A) ("MPIC" or the "Corporation") today provided U.S. tax information for 2010 intended to assist individual U.S. holders ("Unitholders") of the trust units of Macquarie Power & Infrastructure Income Fund (the "Fund"), the predecessor entity to the Corporation. The Fund converted into the Corporation effective January 1, 2011.

The Corporation believes that the Fund should be considered a qualified foreign corporation for U.S. tax purposes and that dividends (as computed under U.S. tax principles) paid to its individual U.S. unitholders should be considered "qualified dividends" (assuming other investor requirements are met) under Section 1(h)(11) of the Internal Revenue Code of 1986, as amended, for U.S. federal income tax purposes. The portion of the distributions made during 2010 that are considered qualified dividends should generally be eligible for the reduced rate of tax applicable to certain long-term capital gains.

The portion of the Fund's distributions that is considered a dividend for U.S. income tax purposes is determined based on the Fund's current and accumulated earnings and profits ("E&P") as determined in accordance with U.S. income tax law. With respect to cash distributions paid in 2010 to U.S. individual unitholders, approximately 21% should be reported as qualified dividends. Approximately 79% of such distributions should be reported as a tax-free return of capital to the extent that the unitholder has sufficient U.S. tax basis in his/her units. Any excess over U.S. tax basis should be reported as a capital gain. 

The Fund provides information in relation to its E&P position for U.S. tax purposes on a voluntary basis. This information is prepared by an external tax advisor on behalf of the Fund. Neither the United States Congress, nor the Treasury, nor the judiciary has provided a comprehensive definition of E&P although section 312 of the Internal Revenue Code, and the regulations thereunder, address certain aspects of its computation. Taxpayers seeking to compute E&P must therefore rely, in part, on inferences based on the function of E&P and its underlying theory, rather than on explicit tax authority. Accordingly, this information is general in nature and is not exhaustive of all possible U.S. tax considerations. The information provided does not constitute legal or tax advice to any holder or potential holder of the Fund's Units. It is strongly recommended that U.S. Unitholders consult with their tax advisors as to the tax consequences of holding Units and concerning the tax consequences of this information that is specific to their own circumstances, including any state, local or foreign tax considerations.

Canadian resident taxpayers should note that the above information has no impact on previously disclosed Canadian tax information.
