ARC Energy Trust 2006 U.S. income tax reporting

CALGARY, March 28 /CNW/ - (AET.UN and ARX - TSX) ARC Energy Trust ("ARC"
or "the Trust") releases supplementary information regarding U.S. tax
reporting:

U.S. Income Tax Information

The following supplementary information is being provided to assist U.S.
individual unitholders of ARC Energy Trust ("ARC") in reporting distributions
received from ARC during 2006 on their Internal Revenue Service ("IRS") Form
1040, "U.S. Individual Income Tax Return" ("Form 1040").
This information is of a general nature only and is not intended to be
legal or tax advice to any particular holder or potential holder of ARC trust
units. Holders or potential holders of ARC trust units should consult their
own legal and tax advisors as to their particular tax consequences of holding
ARC trust units.
As mentioned in our previous news release of February 15, 2007, U.S.
individual unitholders who hold their ARC trust units through a stockbroker or
other intermediary should receive tax reporting information from their
stockbroker or other intermediary. We expect that the stockbroker or other
intermediary will issue a Form 1099-DIV, "Dividends and Distributions" or a
substitute form developed by the stockbroker or other intermediary. ARC is not
required to furnish such unitholders with Form 1099-DIV.
Unlike last year, it has come to ARC's attention that information
reported on the Forms 1099-DIV issued by stockbrokers or other intermediaries
will likely not accurately reflect the "qualified dividend" information
reported in ARC's February 15, 2007 news release to U.S. investors. Such
inconsistency is due to the fact that the firm hired by many stockbrokers and
other intermediaries in the U.S. to compile reporting information on foreign
entities has taken a more conservative position of how foreign entities can
satisfy the safe harbors issued by the IRS for "qualified foreign corporation"
status. Brokers and other intermediaries are not required to issue amended
Forms 1099-DIV, since they are merely following the rules issued by the IRS.
The IRS is aware that there may be instances when the safe harbor
information reporting procedures may not be satisfied, although the reported
dividends are actually qualified dividends. In such a case, IRS Notice 2003-79
indicates "a recipient of Form 1099-DIV may treat a dividend as a qualified
dividend if such person believes the dividend is a qualified dividend, subject
to applicable penalties in the event the amount so reported is not in fact a
qualified dividend."
