SUPPLEMENT DATED FEBRUARY 13, 2007 TO THE PROSPECTUS DATED MAY 1, 2006

This supplement amends the current Prospectus of each of the above-referenced
portfolios (each a "Fund" and together the "Funds"), and is in addition to any
other supplement(s) to each Fund's current Prospectus. Each Fund's Prospectus
is amended by adding the following disclosure:

    The Manager recently reevaluated the financial statement presentation of
certain derivative instruments held by the Funds, which are commonly referred
to as inverse floaters, under the provisions of Statement of Financial
Accounting Standards No. 140 ("FAS 140"). The application of the provisions of
FAS 140 entailed a reclassification of transactions in which a Fund sells a
municipal bond to a special purpose trust in order to create an inverse floater
which the Fund receives from such trust in a financing transaction. The trust
also issues floating rate notes to third parties. The Fund receives interest
payments on inverse floaters that bear an inverse relationship to the interest
paid on the floating rate notes. These transactions were previously classified
as a sale for financial statement presentation purposes. While such inverse
floaters expose the Fund to leverage risk, they do not constitute borrowings
for purposes of the Fund's restrictions on borrowings. The application of the
provisions of FAS 140 with respect to inverse floaters otherwise acquired by
the Fund is not currently subject to this reevaluation.

    Although the Manager believes that the Fund's historical accounting
treatment of inverse floaters has been consistent with prevailing mutual fund
industry accounting practices, it has analyzed the impact of applying FAS 140
to the reporting and presentation of the Funds' inverse floaters in each Fund's
financial statements, including each Fund's Financial Highlights, and has
concluded that the cumulative impact of this change of accounting treatment was
not material to prior financial statements.

   Future financial statements for the Fund will reflect the application of the
provisions of FAS 140, regardless of materiality. Pursuant to FAS 140, the Fund
will record interest on the full amount of the municipal bonds held in the
special purpose trusts as interest income and the Fund also will record the
interest to holders of the floating rate certificates and fees associated with
the trust as interest expense in the Statement of Operations. This change will
cause the Fund's expense ratio to increase. However, neither the Fund's net
income nor its distributions to shareholders is impacted since the increase in
interest expense will be offset by a corresponding amount of increased income
on the bonds now deemed to be owned by the Fund (instead of only the interest
the Fund received on the inverse floater certificates it held directly).

   To the extent that the Fund owns such inverse floaters as of the financial
reporting period end, another important change pursuant to FAS 140 is that the
Fund's gross assets would increase by the par amount of the floating rate
certificates issued by the affected special purpose trusts, with a
corresponding increase in the Fund's liabilities. The Fund's net assets and
net asset value per share should not be affected by this change in
accounting because the increase in gross assets will be offset by a
corresponding increase in liabilities.
