Macquarie Power & Infrastructure Income Fund Provides Tax Information for U.S. Unitholders

TORONTO, ONTARIO (March 31, 2009) – Macquarie Power & Infrastructure Income Fund (TSX: MPT.UN; MPT.DB – “MPT” or the “Fund”), which owns and operates essential infrastructure assets, today provided U.S. tax information to assist individual U.S. holders of the Fund’s units.

This information is general in nature and is not exhaustive of all possible U.S. tax considerations. It is not intended to constitute legal or tax advice to any holder or potential holder of the Fund’s trust units.

The Fund believes that it 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” under the Jobs and Growth Tax Relief Reconciliation Act of 2003 for U.S. federal income tax purposes. The Fund’s traded units more likely than not are properly classified as equity in a corporation, rather than as debt, for U.S. federal income tax purposes. As such, the portion of the distributions made during 2008 that are considered qualified dividends should 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 upon the greater of the Fund’s current or accumulated earnings and profits (“E&P”) as determined in accordance with U.S. income tax law. With respect to cash distributions paid in 2008 to U.S. individual unitholders, 40.0% should be reported as either non-taxable return of capital or capital gain for U.S. federal income tax purposes. This portion of the cash distribution should be a non-taxable return of capital to the extent of the unitholder’s U.S. tax basis in the units and taxable as a capital gain where it is in excess of the unitholder’s U.S. tax basis in the units. Sixty percent of the cash distributions paid in 2008 to U.S. individual unitholders should be reported as qualified dividends.

The Fund is not required to issue Form 1099 DIVs. However, U.S. unitholders may have previously received a Form 1099 DIV from a broker or intermediary that may not be correct. As a result of this, U.S. unitholders should consult their brokers and tax advisors to ensure that this information is accurately reflected on their tax returns. Brokers and/or intermediaries may or may not be required to issue amended Form 1099 DIVs.

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