 Tactical Municipal Closed -End Fund Strategy
The disclosure states that t he Tactical Municipal Closed -End Fund Strategy will seek to “ (ii)
derive value from the discount and premium spreads associated with closed -end funds.”  Please
amplify the disclosure to identify the categories of “closed -end funds” to which the statement
refers.

Municipal Income Bond Strategy

The di sclosure states that the Fund may invest up to 30% of its Managed Assets in Municipal
Bonds that pay interest that may be includable in taxable income for purposes of the Federal
alternative minimum tax.  Expand the disclosure to clarify whether the  30% li mit applies to the
Fund’s investments under both the Tactical Municipal Closed- End Fund Strategy and the
Municipal Income Bond Strategy.

Expand the paragraph that begins with “You should read this prospectus” to include on the
outside front cover all of the additional information that is required by Item 1.1.d. of Form N -2.

Please expand footnote (2) to the pricing table to provide a cross -reference to the section of the
prospectus captioned “Additional Underwriter Compensation.”

In your response letter, please confirm that all of the information that precedes the section
captioned “Table of Contents” will appear on the outside front cover of the prospectus in at least
10-point type.

Contingent Conversion Feature  (page iii)

The disclosure states that the Fund’s Charter provides that, “ during calendar year, ” the Fund will
call a shareholder meeting for the purpose of voting to determine whether the Fund should
convert to an open -end management investment company.   Expand the disclosure to identify in
which calendar year the Fund will call a shareholder meeting for this purpose.  Also, clarify
whether the Fund will not be required to call a meeting to vote on such proposal in subsequent
calendar years should its shareholders fai l to approve the proposal during the applicable calendar
year.

Dividends and Distributions  (page iv)

May the Contingent Quarterly Special Distribution be paid in respect of capital gains?  If so, how
will the payment of the Contingent Quarterly Special D istribution comply with the requirements
of section 19 of the ICA?

Leverage (page iv)

The disclosure states that the Fund may enter into other transactions that have the effect of
leverage, and that such other transactions “ may” include tender option bond transactions.
Additionally, page 7 discloses that the Fund currently anticipates that leverage will initially be
obtained through the use of proceeds received from tender option bond transactions. We also

3
 note from the disclosure appearing on page 56 and elsewhere in the prospectus, that the Fund
may invest in TOB Floaters and TOB Residuals, and that the Fund intends to utilize TOBs as a
form of leverage.  In your response letter, describe how the Fund will treat TOB Floaters, T OB
Residuals, both recourse and non-  recourse, when determining its exposure to leverage, for
purposes of segregating liquid assets and the asset coverage test under section 18(a)(1) under the
Investment Company Act of 1940 (the “ICA”).

Prospectus Summar y
Principal Investment Strategies and Policies  (page 1)

May the Fund invest in entities that are excluded from the definition of “investment company”
under the ICA solely by Section 3(c)(1) or Section 3(c)(7) of the ICA (typically private equity
funds and hedge funds)?  If it may, add disclosure stating that the Fund will limit its investment
in such entities to no more than 15% of its net assets.  In the alternative, confirm in your
response letter that the Fund will not invest in such entities.

State Sp ecific and Industry Risk (page 15)

The disclosure states that the Fund’s overall exposure to a single industry or a single state of
origin may be greater after factoring in the investments of the Underlying Funds, in which case
the Fund may be more susceptible to adverse economic, political  or regulatory occurrences
affecting that particular state or industry.  Please expand the prospectus disclosure  to take into
account the SAI disclosure which i ndicat es that, to the extent that the Fund is aware of the
investments held by the Underlying Funds, the Fund will consider such information when
determining compliance with its fundamental investment restriction governing industry
concentration.

Summary of Fund Expenses  (page 36)

We note that most of the information in the fee table and Example is  incomplete.  Please provide
us with the details of the Fund’s fees, expenses and Example presentation as soon as they are
available.

Footnote (4) states that the management fee and administration fee are charged as a percentage
of the Fund’s average dail y Managed Assets, as opposed to net assets.  Please expand the
disclosure to highlight how  Managed Assets are counted, per the terms of the Investment
Advisory contract, in respect of TOBs transactions .  Specifically, how Managed Assets  are
calculated where the Fund’s receives TOB securities upon a transfer of the Fund’s portfolio
assets, such as a Municipal Bond or other municipal securities, to the sponsor of the TOB
vehicle, as described on page 46.

We note from footnote (5) that the “Leverage Cost s” fee table line item assumes the use of
leverage from the proceeds of tender option bond transactions using an assumed annual interest
rate expense to the Fund.   Clarify where in the Fund’s fee table the other expenses of TOBs
transactions  are included , such as those expenses identified on page 47 related to remarketing,
administration and trustee services to a TOB Issuer .

Net Asset Value (page 73 )

In your response letter, please inform the staff whether the Fund’s  Board of Directors will review
and approve in advance the valuation methodology of any independent valuation firm it uses and
confirm that the Fund’s Board of Directors will regularly review the historical accuracy of its fair
value methodologies.  See Re lease No. IC -26299; “Compliance Programs of Investment
Companies and Investment Advisers,”  (December 17, 2003).

Dividend Reinvestment Plan (page 76)

Disclose that reinvested dividends increase the Fund's total Managed Assets on which a
management fee is payable to Fund's Adviser.

Approval of Extraordinary Corporate Actions  (page 80)

The disclosure presented in the section identifies various  matters specified by the Fund’s Charter
as requiring either a favorable “supermajority” vote or a favorable “ two-thirds”  vote in order “to
advise, approve, adopt or authorize” the m atters  identified.   We note, however, that certain of the
matters  identified , as well as their related voting requirements, are specifically governed by the
ICA.  Please reconcile, in each instance, the voting requirements  specified by the Fund’s Charter
pertaining to those matters specifically governed by the ICA , with the applicable voting
requirements specified by the ICA .

Underwriters  (page 91)

Please confirm to the staff whether FINRA has approved the underwriting terms of the Fund’s
offering.

Additional Underwriter Compensation (page 91)

Statement of Additional Information
Investment Restrictions (page 1)
The second paragraph states that any of the Fund’s fundamental investment restrictions that
involve a maximum percentage of securities or assets shall not be considered to be violated
unless an excess over the percentage occur s immediately after and is caused by an acquisition or
encumbrance of securities or assets of,  or borrowings by, the Fund.  Please note that , under the
ICA, the asset coverage requirement applicable to borrowings must be maintained on an ongoing
basis.   Accordingly, please revise the discl osure  to reflect this requirement.

In the fourth enumerated fundamental policy, please insert the phrase “or group of industries”
after the phrase “single industry.”

5

The narrative disclosure supplementing the Fund’s presentation of its fundamental investment
restriction  (4) states that the limitation on industry concentration will apply to municipal
securities if the payment of principal and interest for such securities is derived “solely from” a
specific project .  In that situation , the Fund will consider such municipal securities to be in an
industry.  Please expand the disclosure to state  that the industry of a non-governmental user or of
a project being funded will be counted for concentration purposes where s uch securities are
backed principally by non- governmental assets and revenues.   In this regard, where a
governmental entity commits to providing support only in case the assets and revenues of the
non-governmental user are insufficient to satisfy the oblig ations under the debt, the debt is
considered being backed “principally” by the revenues and assets of the nongovernmental user
and, therefore, will be counted towards the industry of the user for concentration purposes.

Board Members and Officers  (page 3 1)

Please disclose all of the other information required by Item 18 of Form N -2 in the next
submission of the prospectus.  In this regard, the section captioned “Director Qualifications”
should present information for each director that briefly identifies the specific  experience,
qualifications, attributes, or skills that led to the conclusion that the person should serve as a
director for the Fund at the time that the disclosure is made, in light of the Fund’s business and
structure. See  Item 18.17 of Form N -2.
Signatures
Prior to effectiveness of the registration statement, the Fund must have a board of directors
whose composition complies with the applicable provisions of the ICA.  Also, please note the
signature requirements of Sectio n 6(a) of the Securities Act, which requires that the registration
statement be signed by a majority of the Fund’s Board of Directors.
