| | At least 80%
of the Fund’s net assets (including net assets attributable to Preferred
shares) are invested in |
| --- | --- |
| | municipal
securities that are either covered by Original Issue Insurance, Secondary Market
Insurance or |
| | Portfolio
Insurance which ensures the timely payment of principal and interest. Up to 20% of
the Fund’s |
| | net assets
(including net assets attributable to Preferred shares) may be invested in
municipal securities |
| | that are (i)
either backed by an escrow or trust containing sufficient U.S. Government or U.S.
Government |
| | agency
securities (also ensuring the timely payment of principal and interest), or (ii)
rated, at the time of |
| | investment,
within the four highest grades (Baa or BBB or better by Moody’s, Standard
& Poor’s or Fitch) |
| | or unrated but
judged to be of comparable quality by the Adviser. |
| | The Fund may
invest in “zero coupon” securities. A zero coupon security does not pay
a regular interest |
| | coupon to its
holders during the life of the security. Tax-exempt income to the holder of the
security comes |
| | from accretion
of the difference between the original purchase price of the security at issuance
and the |
| | par value of
the security at maturity and is effectively paid at maturity. Such securities are
included in the |
| | Portfolio of
Investments with a 0.000% coupon rate in their description. The market prices of
zero coupon |
| | securities
generally are more volatile than the market prices of securities that pay interest
periodically. |
| (1) | All
percentages shown in the Portfolio of Investments are based on net assets
applicable to Common |
| | shares unless
otherwise noted. |
| (2) | Optional Call
Provisions: Dates (month and year) and prices of the earliest optional call or
redemption. |
| | There may be
other call provisions at varying prices at later dates. Certain mortgage-backed
securities |
| | may be subject
to periodic principal paydowns. |
| (3) | Ratings: Using
the higher of Standard & Poor’s Group (“Standard &
Poor’s”) or Moody’s Investor Service, |
| | Inc.
(“Moody’s”) rating. Ratings below BBB by Standard &
Poor’s or Baa by Moody’s are considered to be |
| | below
investment grade. |
| | The AAA
ratings shown in the Portfolio of Investments reflect the AAA ratings on certain
bonds that may |
| | be insured by
AMBAC, FGIC, XLCA or MBIA as of January 31, 2008. Subsequent to January 31, 2008,
at |
| | least one
rating agency reduced the rating for AMBAC-insured bonds to AA and XLCA-insured
and |
| | FGIC-insured
bonds experienced further downgrades such that they no longer carry AAA ratings
which had |
| | the effect of
reducing the rating of many (if not all) of the bonds insured by those particular
insurers. One |
| | or more rating
agencies have placed each of these insurers on “negative credit watch”,
which may presage |
| | one or more
rating reductions for such insurer or insurers in the future. If one or more
insurers’ ratings are |
| | reduced below
AAA by these rating agencies, it would likely reduce the effective rating of many
of the |
| | bonds insured
by that insurer or insurers. |
| (4) | Preferred
Shares, at Liquidation Value as a percentage of total investments is
(33.5)%. |
| (IF) | Inverse
floating rate investment. |
| (UB) | Underlying
bond of an inverse floating rate trust reflected as a financing transaction
pursuant to the |
| | provisions of
SFAS No. 140. |

Income Tax Information

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to the treatment of paydown gains and losses, timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate transactions subject to SFAS No.140. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts on the Statement of Assets and Liabilities presented in the annual report, based on their federal tax basis treatment; temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset value of the Fund.
