77d

The fund is required to comply with asset coverage tests and
other investment restrictions set forth in your funds Bylaws.
These requirements are imposed by the rating agencies that rate
the funds preferred shares.  In December, 2007, the funds Bylaws
were amended to expand the categories of investments that may be
counted toward meeting the asset coverage tests and to liberalize
the calculations applied to those investments.  The amendment
effectively increases the funds ability to invest in various
derivative and lower-rated instruments. Specifically, (a) zero
coupon bonds and swaps (including total return swaps, interest
rate swaps, currency swaps and credit default swaps) may now be
included when performing asset coverage tests; (b) the minimum
original issue size of a qualified municipal obligation has been
reduced; (c) pre-refunded bonds will now be discounted like
AAA/Aaa-rated bonds even if they are not re-rated; and (d) the
discount factors assigned to investments will be reduced, making
it easier for the fund to satisfy the asset coverage tests.  This
additional investment flexibility may increase the funds exposure
to credit risk and to risks associated with derivatives, some of
which are described below.
