     The aggregate net asset value of the MuniYield New York Insured II Common
Stock to be issued to MuniVest New York Insured and thereafter distributed to
the holders of shares of Common Stock, par value $.10 per share, of MuniVest New
York Insured ("MuniVest New York Insured Common Stock") will equal the aggregate
net asset value of the shares of MuniVest New York Insured Common Stock on the
date of the Reorganization. Similarly, it is intended that the aggregate
liquidation preference and value of the MuniYield New York Insured II Series B
AMPS to be issued to MuniVest New York Insured and thereafter distributed to the
holders of shares of AMPS of MuniVest New York Insured, with a liquidation
preference of $25,000 per share plus an amount equal to accumulated but unpaid
dividends thereon (whether or not earned or declared) ("MuniVest New York
Insured AMPS") will equal the aggregate liquidation preference and value of the
MuniVest New York Insured AMPS on the date of the Reorganization. As soon as
practicable after the receipt by MuniYield New York Insured II of all of
MuniVest New York Insured's assets and the assumption by MuniYield New York
Insured II of all of MuniVest New York Insured's liabilities, MuniVest New York
Insured will distribute the MuniYield New York Insured II Common Stock and
MuniYield New York Insured II Series B AMPS to MuniVest New York Insured's
stockholders as described under "The Reorganization". Thereafter, MuniVest New
York Insured will terminate its registration under the Investment Company Act of
1940, as amended (the "Investment Company Act"), and will liquidate and dissolve
in accordance with the laws of the State of Maryland.
 
     In addition, the aggregate net asset value of the MuniYield New York
Insured II Common Stock to be issued to MuniYield New York Insured III and
thereafter distributed to the holders of shares of Common Stock, par value $.10
per share, of MuniYield New York Insured III ("MuniYield New York Insured III
Common Stock") will equal the aggregate net asset value of the shares of
MuniYield New York Insured III Common Stock on the date of the Reorganization.
Similarly, it is intended that the aggregate liquidation preference and value of
the MuniYield New York Insured II Series C AMPS to be issued to MuniYield New
York Insured III and thereafter distributed to the holders of shares of AMPS of
MuniYield New York Insured III, with a liquidation preference of $25,000 per
share plus an amount equal to accumulated but unpaid dividends thereon (whether
or not earned or declared) ("MuniYield New York Insured III AMPS") will equal
the aggregate liquidation preference and value of the MuniYield New York Insured
III AMPS on the date of the Reorganization. As soon as practicable after the
receipt by MuniYield New York Insured II of all of MuniYield New York Insured
III's assets and the assumption by MuniYield New York Insured II of all of
MuniYield New York Insured III's liabilities, MuniYield New York Insured III
will distribute the MuniYield New York Insured II Common Stock and MuniYield New
York Insured II Series C AMPS to MuniYield New York Insured III's stockholders
as described under "The Reorganization". Thereafter, MuniYield New York Insured
III will terminate its registration under the Investment Company Act and will
liquidate and dissolve in accordance with the laws of the State of Maryland.
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III are non-diversified, leveraged, closed-end management
investment companies with virtually identical investment objectives. Each of the
Funds seeks to provide stockholders with as high a level of current income
exempt from Federal, New York State and New York City income taxes as is
consistent with their respective investment policies and prudent investment
management. Each of the Funds seeks to achieve its investment objective by
investing primarily in a portfolio of long-term municipal obligations issued by
or on behalf of the State of New York, its political subdivisions, agencies and
instrumentalities and by other qualifying issuers that pay interest which, in
the opinion of bond counsel to the issuer, is exempt from Federal, New York
State and New York City income taxes ("New York Municipal Bonds"). There can be
no assurance that after the Reorganization the surviving fund will achieve the
investment objective of either MuniVest New York Insured, MuniYield New York
Insured II or MuniYield New York Insured III.
 
     MuniVest New York Insured Common Stock, MuniYield New York Insured II
Common Stock and MuniYield New York Insured III Common Stock are listed on the
New York Stock Exchange (the "NYSE") under the symbols "MVY", "MYT" and "MYY",
respectively. Subsequent to the Reorganization, shares of MuniYield New York
Insured II Common Stock will continue to be listed on the NYSE under the symbol
"MYT". Reports, proxy materials and other information concerning any of the
Funds may be inspected at the offices of the NYSE, 11 Wall Street, New York, New
York 10005.

                               THE REORGANIZATION
 
SUMMARY
 
     The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus and is qualified in its entirety by
reference to the more complete information contained in this Proxy Statement and
Prospectus and in the Agreement and Plan of Reorganization, attached hereto as
Exhibit I.
 
     In this Proxy Statement and Prospectus, the term "Reorganization" refers
collectively to (i) the acquisition of all of the assets and the assumption of
all of the liabilities of MuniVest New York Insured by MuniYield New York
Insured II and the subsequent distribution of MuniYield New York Insured II
Common Stock and MuniYield New York Insured II Series B AMPS to the holders of
MuniVest New York Insured Common Stock and MuniVest New York Insured AMPS,
respectively; (ii) the acquisition of all of the assets and the assumption of
all of the liabilities of MuniYield New York Insured III by MuniYield New York
Insured II and the subsequent distribution of MuniYield New York Insured II
Common Stock and MuniYield New York Insured II Series C AMPS to the holders of
MuniYield New York Insured III Common Stock and MuniYield New York Insured III
AMPS, respectively; (iii) the redesignation of the currently outstanding series
of MuniYield New York Insured II AMPS as Series A AMPS; and (iv) the subsequent
deregistration and dissolution of each of MuniVest New York Insured and
MuniYield New York Insured III.
 
     At meetings of the Boards of Directors of MuniVest New York Insured and
MuniYield New York Insured III held on May 3, 1996, and at a meeting of the
Board of Directors of MuniYield New York Insured II held on June 21, 1996, the
Board of Directors of each of the Funds unanimously approved a proposal, as
applicable, that (i) MuniYield New York Insured II acquire all of the assets,
and assume all of the liabilities, of MuniVest New York Insured in exchange
solely for MuniYield New York Insured II Common Stock and MuniYield New York
Insured II Series B AMPS to be issued to MuniVest New York Insured and
thereafter distributed to the stockholders of MuniVest New York Insured; and/or
(ii) MuniYield New York Insured II acquire all of the assets, and assume all of
the liabilities, of MuniYield New York Insured III in exchange solely for
MuniYield New York Insured II Common Stock and MuniYield New York Insured II
Series C AMPS to be issued to MuniYield New York Insured III and thereafter
distributed to the stockholders of MuniYield New York Insured III. Subject to
obtaining the necessary approvals from
 
                                        7
   12
 
the stockholders of MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III, the Board of Directors of each of MuniVest New
York Insured and MuniYield New York Insured III deemed advisable the
deregistration of MuniVest New York Insured or MuniYield New York Insured III,
as applicable, under the Investment Company Act and its respective dissolution
under the laws of the State of Maryland.
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III seek to provide stockholders with as high a level of current
income exempt from Federal, New York State and New York City income taxes as is
consistent with their respective investment policies and prudent investment
management. Each of the Funds seeks to achieve its investment objectives by
investing primarily in a portfolio of New York Municipal Bonds. At all times,
except during temporary defensive periods, at least 65% of each Fund's total
assets will be invested in New York Municipal Bonds. Under normal circumstances,
at least 80% of each Fund's total assets will be invested in New York Municipal
Bonds and other municipal bonds the interest on which, in the opinion of bond
counsel to the issuer, is exempt from Federal income taxes but not New York
State or New York City income taxes ("Municipal Bonds"), with remaining
maturities of one year or more which are covered by insurance guaranteeing the
timely payment of principal at maturity and interest. Unless otherwise
indicated, references herein to Municipal Bonds shall be deemed to include New
York Municipal Bonds.
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III are non-diversified, leveraged, closed-end management
investment companies registered under the Investment Company Act. If the
stockholders of MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III approve the Reorganization, MuniYield New York
Insured II Common Stock, MuniYield New York Insured II Series B AMPS and
MuniYield New York Insured II Series C AMPS will be issued to MuniVest New York
Insured and MuniYield New York Insured III, as applicable, in exchange for the
assets of MuniVest New York Insured and MuniYield New York Insured III and
thereafter MuniVest New York Insured and MuniYield New York Insured III will
distribute these shares to its stockholders as provided in the Agreement and
Plan of Reorganization. After the Reorganization, each of MuniVest New York
Insured and MuniYield New York Insured III will terminate its registration under
the Investment Company Act and its incorporation under Maryland law.
 
     Based upon their evaluation of all relevant information, the Directors of
MuniVest New York Insured, MuniYield New York Insured II and MuniYield New York
Insured III have determined that the Reorganization will potentially benefit the
holders of Common Stock of each of the Funds. Specifically, after the
Reorganization MuniVest New York Insured and MuniYield New York Insured III
stockholders will remain invested in a closed-end fund that has an investment
objective and policies virtually identical to those of MuniVest New York Insured
and MuniYield New York Insured III and which utilizes the same management
personnel. In addition, it is anticipated that common stockholders of MuniVest
New York Insured, MuniYield New York Insured II and MuniYield New York Insured
III will be subject to a reduced overall operating expense ratio based on the
combined assets of the surviving fund after the Reorganization. It is not
anticipated that the Reorganization will directly benefit the holders of shares
of MuniVest New York Insured AMPS, MuniYield New York Insured II AMPS or
MuniYield New York Insured III AMPS; however, the Reorganization will not
adversely affect the holders of shares of AMPS of any of the Funds and the
expenses of the Reorganization will not be borne by the holders of shares of
AMPS of any of the Funds.
 
                                        8

     In deciding to recommend the Reorganization, the Boards of Directors of
MuniVest New York Insured, MuniYield New York Insured II and MuniYield New York
Insured III took into account the investment objective and policies of each of
the Funds, the expenses incurred both due to the Reorganization and on an
ongoing basis by the new and existing stockholders of MuniYield New York Insured
II and the potential benefits, including economies of scale, to the holders of
Common Stock and AMPS of MuniVest New York Insured, MuniYield New York Insured
II and MuniYield New York Insured III as a result of the Reorganization. The
Board of Directors of each of the Funds, including all of the Directors who are
not "interested persons", as defined in the Investment Company Act, of each of
the Funds, has determined that the Reorganization is in the best interests of
each of the Funds and of the holders of Common Stock and AMPS of each of the
Funds and that the interests of such stockholders will not be diluted as a
result of effecting the Reorganization.
 
     If all of the requisite approvals are obtained, it is anticipated that the
Reorganization will occur as soon as practicable after such approval, provided
that the Funds have obtained prior to that time a favorable private letter
ruling from the Internal Revenue Service (the "IRS") concerning the tax

     for bulk purchases. Shares of Common Stock purchased on the secondary
     market are not subject to sales loads, but may be subject to brokerage
     commissions or other charges.
 
(c)  No sales load will be charged on the issuance of shares in the
     Reorganization. Shares of Common Stock are not available for purchase from
     the Funds but may be purchased through a broker-dealer subject to

                                 Net Asset Value.  The net asset value per share
                                   of Common Stock of each Fund is determined as
                                   of 15 minutes after the close of business on
                                   the NYSE (generally, 4:00 P.M., New York
                                   time) on each day during which the NYSE is
                                   open for trading. For purposes of determining
                                   the net asset value of a share of Common
                                   Stock of each Fund, the value of the
                                   securities held by the Fund plus any cash or
                                   other assets (including interest accrued but
                                   not yet received) minus all liabilities
                                   (including accrued expenses) and the
                                   aggregate liquidation value of the
                                   outstanding shares of AMPS of the Fund is
                                   divided by the total number of shares of
                                   Common Stock of the Fund outstanding at such
                                   time. Expenses, including the fees payable to
                                   FAM, are accrued daily. See "Comparison of

                                 Stockholder Services.  An automatic dividend
                                   reinvestment plan is available to the holders
                                   of shares of MuniVest New York Insured Common

                                   other things, neither MuniVest New York

RISK FACTORS AND SPECIAL CONSIDERATIONS
 
     Since each of the three Funds invests primarily in a portfolio of Municipal
Bonds, any risks inherent in such investments are equally applicable to all
three Funds and will be similarly pertinent to the combined fund after the
Reorganization. It is expected that the Reorganization itself will not adversely
affect the rights of holders of shares of Common Stock or AMPS of any of the
Funds or create additional risks.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK MUNICIPAL BONDS
 
     Each of the Funds ordinarily invests substantially all of its total assets
in New York Municipal Bonds and, therefore, each Fund is more susceptible to
factors adversely affecting issuers of New York Municipal Bonds than is a
municipal bond investment company that is not concentrated in issuers of New
York Municipal Bonds to this degree. In recent years, New York State, New York
City and other New York public bodies have encountered financial difficulties
which could have an adverse effect with respect to the performance of each of
the Funds. As of April 18, 1996, Moody's, S&P and Fitch Investors Service, Inc.
("Fitch") rated New York City's general obligation bonds Baa1, BBB+ and A-,
respectively. On February 28, 1996, Fitch placed New York City's general
obligation bonds on FitchAlert with negative implications. On July 10, 1995, S&P
revised downward its rating on outstanding general obligation bonds of New York
City from "A-" to "BBB+". Moody's, S&P and Fitch currently rate New York State's
general obligation bonds A, A- and A+, respectively. FAM does not believe that
the current economic conditions in New York will have a significant adverse
effect on a Fund's ability to invest prudently in New York Municipal Bonds. See
Exhibit II -- "Economic and Financial Conditions in New York".
 
EFFECTS OF LEVERAGE
 
     Utilization of leverage, through the issuance of AMPS, involves certain
risks to holders of MuniVest New York Insured Common Stock, MuniYield New York
Insured II Common Stock and MuniYield New York Insured III Common Stock. For
example, each Fund's issuance of AMPS may result in higher volatility of the net
asset value of its Common Stock and potentially more volatility in the market
value of its Common Stock. In addition, fluctuations in the short-term and
medium-term dividend rates on, and the amount of taxable income allocable to,
the AMPS affect the yield to holders of Common Stock. So long as each Fund,
taking into account the costs associated with its AMPS and the Fund's operating
expenses, is able to realize a higher net return on its investment portfolio
than the then-current dividend rate on the AMPS, the effect of leverage is to
cause holders of the Fund's Common Stock to realize a higher current rate of
return than if the Fund were not leveraged. Similarly, since a pro rata portion
of each Fund's net realized capital gains on its investment assets generally is
payable to holders of the Fund's Common Stock, if increased net capital gains
are realized by the Fund because of increased capital for investment, the effect
of leverage will be to increase the amount of such gains distributed to holders
of the Fund's Common Stock. However, short-term, medium-term and long-term
interest rates change from time to time as does their relationship to each other
(i.e., the slope of the yield curve) depending upon such factors as supply and
demand forces, monetary and tax policies and investor expectations. Changes in
such factors could cause the relationship between short-term, medium-term and
long-term rates to change (i.e., to flatten or to invert the slope of the yield
curve) so that short-term and medium-term rates may increase substantially
relative to the long-term obligations in which each Fund may be invested. To the
extent that the current dividend rate on the AMPS approaches the net return on a
Fund's investment portfolio, the benefit of leverage to holders of Common Stock
is reduced,
 
                                       19
   24
 
and if the current dividend rate on the AMPS were to exceed the net return on a
Fund's portfolio, the Fund's leveraged capital structure would result in a lower
rate of return to holders of Common Stock than if the Fund were not leveraged.
Similarly, since both the costs associated with the issuance of AMPS and any
decline in the value of a Fund's investments (including investments purchased
with the proceeds from any AMPS offering) are borne entirely by holders of the
Fund's Common Stock, the effect of leverage in a declining market would result
in a greater decrease in net asset value to holders of Common Stock than if the
Fund were not leveraged. Such decrease in net asset value likely would be
reflected in a greater decline in the market price for shares of Common Stock.
 
     In an extreme case, a decline in net asset value could affect each Fund's
ability to pay dividends on its Common Stock. Failure to make such dividend
payments could adversely affect the Fund's qualification for the special tax
treatment afforded RICs under the Code. See "Agreement and Plan of
Reorganization -- Tax Consequences of the Reorganization". Each Fund intends,
however, to take all measures necessary to continue to make Common Stock
dividend payments. If a Fund's current investment income were not sufficient to
meet dividend requirements on either the Common Stock or the AMPS, it could be
necessary for the Fund to liquidate certain of its investments. In addition,
each Fund has the authority to redeem its AMPS for any reason and may redeem all
or part of its AMPS if (i) the Fund anticipates that its leveraged capital
structure will result in a lower rate of return for any significant amount of
time to holders of the Common Stock than that obtainable if the Common Stock
were unleveraged or (ii) the asset coverage (as defined in the Investment
Company Act) for the AMPS declines below 200% or the Fund fails to satisfy the
guidelines specified by Moody's and S&P in connection with their respective
rating of the AMPS. Redemption of the AMPS or insufficient investment income to
make dividend payments may reduce the net asset value of the Common Stock and
require the Fund to liquidate a portion of its investments at a time when it may
be disadvantageous, in the absence of such extraordinary circumstances, to do
so.
 
PORTFOLIO MANAGEMENT
 
     The portfolio management strategies of MuniVest New York Insured, MuniYield
New York Insured II and MuniYield New York Insured III are the same. In the
event of an increase in short-term or medium-term rates or other change in
market conditions to the point where a Fund's leverage could adversely affect
holders of Common Stock as noted above, or in anticipation of such changes, each
Fund may attempt to shorten the average maturity of its investment portfolio,
which would tend to offset the negative impact of leverage on holders of its
Common Stock. Each Fund also may attempt to reduce the degree to which it is
leveraged by redeeming AMPS pursuant to the provisions of the Fund's Articles
Supplementary establishing the rights and preferences of the AMPS or otherwise
purchasing shares of AMPS. Purchases and sales or redemptions of AMPS, whether
on the open market or in negotiated transactions, are subject to limitations
under the Investment Company Act. If market conditions subsequently change, each
Fund may sell previously unissued shares of AMPS or shares of AMPS that the Fund
previously issued but later repurchased or redeemed.
 
RATINGS CONSIDERATIONS
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III have received ratings of their AMPS of AAA from S&P and "aaa"
from Moody's. In order to maintain these ratings, the Funds are required to
maintain portfolio holdings meeting specified guidelines of such rating
 
                                       20
   25
 
agencies. These guidelines may impose asset coverage requirements that are more
stringent than those imposed by the Investment Company Act.
 
     As described by Moody's and S&P, a preferred stock rating is an assessment
of the capacity and willingness of an issuer to pay preferred stock obligations.
The ratings of the AMPS are not recommendations to purchase, hold or sell shares
of AMPS, inasmuch as the ratings do not comment as to market price or
suitability for a particular investor, nor do the rating agency guidelines
address the likelihood that a holder of shares of AMPS will be able to sell such
shares in an auction. The ratings are based on current information furnished to
Moody's and S&P by the Funds and FAM and information obtained from other
sources. The ratings may be changed, suspended or withdrawn as a result of
changes in, or the unavailability of, such information. Neither the MuniVest New
York Insured Common Stock, the MuniYield New York Insured II Common Stock nor
the MuniYield New York Insured III Common Stock has been rated by a nationally
recognized statistical rating organization.
 
     The Board of Directors of each of MuniVest New York Insured, MuniYield New
York Insured II and MuniYield New York Insured III, as the case may be, without
stockholder approval, may amend, alter or repeal certain definitions or
restrictions which have been adopted by the Fund pursuant to the rating agency
guidelines, in the event the Fund receives confirmation from the rating agencies
that any such amendment, alteration or repeal would not impair the ratings then
assigned to shares of AMPS.

     As indicated in the tables above, since November 1, 1993 the MuniVest New
York Insured Common Stock, the MuniYield New York Insured II Common Stock and
the MuniYield New York Insured III Common Stock generally have traded at prices
close to net asset value, with small premiums or discounts to net asset value
being reflected in the market value of the shares from time to time. Since
November 1, 1993, share prices for MuniVest New York Insured Common Stock have
fluctuated between a maximum premium of 6.54% and a maximum discount of
(17.94%), share prices for MuniYield New York Insured II Common Stock have
traded at a maximum discount of (20.07%), and share prices for MuniYield New
York Insured III Common Stock have fluctuated between a maximum premium of 2.74%
and a maximum discount of (19.06%). Although there is no reason to believe that
this pattern should be affected by the Reorganization, it is not possible to
state whether shares of the surviving fund will trade at a premium or discount
to net asset value following the Reorganization, or what the extent of any such
premium or discount might be.
 
INVESTMENT OBJECTIVE AND POLICIES
 
     The structure, organization and investment policies of MuniVest New York
Insured, MuniYield New York Insured II and MuniYield New York Insured III are
virtually identical, with the minor differences between the three Funds set
forth below. Each Fund seeks as a fundamental investment objective as high a
level of current income exempt from Federal, New York State and New York City
income taxes as is consistent with the Fund's investment policies and prudent
investment management.
 
                                       28
   33
 
     The investment objective and policies of each of the three Funds are
identical. Each Fund seeks to achieve its investment objective by investing
primarily in a portfolio of New York Municipal Bonds. The investment objective
of each Fund is a fundamental policy that may not be changed without a vote of a
majority of the Fund's outstanding voting securities. At all times, except
during temporary defensive periods, at least 65% of each Fund's total assets
will be invested in New York Municipal Bonds. Under normal circumstances, at
least 80% of each Fund's total assets will be invested in New York Municipal
Bonds and Municipal Bonds with remaining maturities of one year or more which
are covered by insurance guaranteeing the timely payment of principal at
maturity and interest. At times, each Fund may seek to hedge its portfolio
through the use of futures and options transactions to reduce volatility in the
net asset value of its shares of Common Stock.
 
     Ordinarily, none of the Funds intends to realize significant investment
income not exempt from Federal, New York State and New York City income taxes.
Each Fund seeks to invest substantially all of its total assets in Municipal
Bonds except at times when, in the judgment of FAM, Municipal Bonds of
sufficient quality and quantity are unavailable for investment by the Fund. Each
Fund may invest in certain tax-exempt securities classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities) that may
subject certain investors in the Fund to an alternative minimum tax.
 
     The investment grade Municipal Bonds in which each Fund invests are those
Municipal Bonds rated at the date of purchase within the four highest rating
categories of S&P, Moody's or Fitch or, if unrated, are considered to be of
comparable quality by FAM. In the case of long-term debt, the investment grade
rating categories are AAA through BBB for S&P, Aaa through Baa3 for Moody's and
AAA through BBB- for Fitch. In the case of short-term notes, the investment
grade rating categories are SP-1 through SP-3 for S&P, MIG-1 through MIG-4 for
Moody's and F-1+ through F-4 for Fitch. In the case of tax-exempt commercial
paper, the investment grade rating categories are A through A-3 for S&P, Prime-1
through Prime-3 for Moody's and F-l+ through F-4 for Fitch. Obligations ranked
in the fourth highest rating category assigned long-term debt or in an
equivalent short-term rating category (BBB, SP-3 and A-3 for S&P; Baa, MIG-4 and
Prime-3 for Moody's; and BBB, F-3 and F-4 for Fitch), while considered
"investment grade," may have certain speculative characteristics. In assessing
the quality of Municipal Bonds with respect to the foregoing requirements, FAM
takes into account the portfolio insurance as well as the nature of any letters
of credit or similar credit enhancement to which particular Municipal Bonds are
entitled and the creditworthiness of the insurance company or other financial
institution which provided such credit enhancement. See Exhibit III -- "Ratings
of Municipal Bonds and Commercial Paper" and Exhibit IV -- "Portfolio
Insurance".
 
     Each of the Funds may invest in variable rate demand obligations ("VRDOs")
and VRDOs in the form of participation interests ("Participating VRDOs") in
variable rate tax-exempt obligations held by a financial institution, typically
a commercial bank. The VRDOs in which each Fund may invest are tax-exempt
obligations (in the opinion of counsel to the issuer) which contain a floating
or variable interest rate adjustment formula and an unconditional right of
demand on the part of the holder thereof to receive payment of the unpaid
principal balance plus accrued interest on a short notice period not to exceed
seven days. Participating VRDOs provide each Fund with a specified undivided
interest (up to 100%) of the underlying obligation and the right to demand
payment of the unpaid principal balance plus accrued interest on the
Participating VRDOs from the financial institution on a specified number of
days' notice, not to exceed seven days. There is, however, the possibility that
because of default or insolvency, the demand feature of VRDOs or
 
                                       29
   34
 
Participating VRDOs may not be honored. Each Fund has been advised by its
counsel that the Fund should be entitled to treat the income received on
Participating VRDOs as interest from tax-exempt obligations.
 
     The average maturity of each Fund's portfolio securities varies based upon
FAM's assessment of economic and market conditions. The net asset value of the
shares of common stock of a closed-end investment company, such as each Fund,
which invests primarily in fixed-income securities, changes as the general
levels of interest rates fluctuate. When interest rates decline, the value of a
fixed income portfolio can be expected to rise. Conversely, when interest rates
rise, the value of a fixed-income portfolio can be expected to decline. Prices
of longer-term securities generally fluctuate more in response to interest rate
changes than do short-term or medium-term securities. These changes in net asset
value are likely to be greater in the case of a fund having a leveraged capital
structure, such as the Funds.
 
     On a temporary basis, each Fund may invest in short-term tax-exempt
securities, short-term U.S. Government securities, repurchase agreements or
cash. Such securities or cash will not exceed 20% of each Fund's total assets
except during interim periods pending investment of the net proceeds from public
offerings of the Fund's securities and temporary defensive periods when, in the
opinion of FAM, prevailing market or economic conditions warrant.
 
     Each Fund is classified as non-diversified within the meaning of the
Investment Company Act, which means that the Fund is not limited by such Act in
the proportion of its total assets that it may invest in securities of a single
issuer. However, each Fund's investments are limited so as to qualify the Fund
for the special tax treatment afforded RICs under the Code. See "Agreement and
Plan of Reorganization -- Tax Consequences of the Reorganization". To qualify,
among other requirements, each Fund limits its investments so that, at the close
of each quarter of the taxable year, (i) not more than 25% of the market value
of the Fund's total assets are invested in the securities (other than U.S.
Government securities) of a single issuer, and (ii) with respect to 50% of the
market value of its total assets, not more than 5% of the market value of its
total assets are invested in the securities (other than U.S. Government
securities) of a single issuer. A fund which elects to be classified as
"diversified" under the Investment Company Act must satisfy the foregoing 5%
requirement with respect to 75% of its total assets. To the extent that any of
MuniVest New York Insured, MuniYield New York Insured II or MuniYield New York
Insured III assumes large positions in the securities of a small number of
issuers, the Fund's yield may fluctuate to a greater extent than that of a
diversified company as a result of changes in the financial condition or in the
market's assessment of the issuers.
 
PORTFOLIO INSURANCE
 
     Under normal circumstances, at least 80% of each Fund's assets will be
invested in Municipal Bonds either (i) insured under an insurance policy
purchased by the Fund or (ii) insured under an insurance policy obtained by the
issuer thereof or any other party. The insurance policies in either instance
will be issued by insurance carriers that have total admitted assets (unaudited)
of at least $75,000,000 and capital and surplus (unaudited) of at least
$50,000,000 and insurance claims-paying ability ratings of AAA from S&P, Aaa
from Moody's or AAA from Fitch. See Exhibit IV to this Proxy Statement and
Prospectus for a brief description of S&P's and Moody's insurance claims-paying
ability ratings. Currently, a majority of the insured Municipal Bonds in each
Fund's portfolio are insured by the following insurance companies which satisfy
the foregoing requirements: AMBAC Indemnity Corporation, Capital Guaranty
Insurance Company, Connie Lee Insurance Co., Financial Guaranty Insurance
Company, Financial Security Assurance and Municipal Bond
 
                                       30
   35
 
Investors Assurance Corporation. Each Fund also may purchase Municipal Bonds
covered by insurance issued by any other insurance company which satisfies the
foregoing requirements. A majority of insured Municipal Bonds held by each Fund
will be insured under policies obtained by parties other than the Fund.
 
     Each Fund may purchase, but has no obligation to purchase, separate mutual
fund insurance policies (the "Policies") from insurance companies meeting the
requirements set forth above which guarantee payment of principal and interest
on specified eligible Municipal Bonds purchased by the Fund. A Municipal Bond
will be eligible for coverage if it meets certain requirements of the insurance
company set forth in a Policy. In the event interest or principal on an insured
Municipal Bond is not paid when due, the insurer will be obligated under its
Policy to make such payment not later than 30 days after it has been notified
by, and provided with documentation from, the Fund that such nonpayment has
occurred.
 
     The Policies will be effective only as to insured Municipal Bonds
beneficially owned by a Fund. In the event of a sale of any Municipal Bonds held
by a Fund, the issuer of the relevant Policy will be liable only for those
payments of interest and principal which are then due and owing. The Policies
will not guarantee the market value of the insured Municipal Bonds or the value
of the shares of the Fund.
 
     The insurer will not have the right to withdraw coverage on securities
insured by its Policies and held by a Fund so long as such securities remain in
the Fund's portfolio. In addition, the insurer may not cancel its Policies for
any reason except failure to pay premiums when due. The Board of Directors of
each Fund reserves the right to terminate any of the Policies if it determines
that the benefits to the Fund of having its portfolio insured under such Policy
are not justified by the expense involved.
 
     The premiums for the Policies are paid by a Fund and the yield on the
Fund's portfolio is reduced thereby. FAM estimates that the cost of the annual
premiums for the Policies of each Fund currently range from approximately .20 of
1% to .25 of 1% of the principal amount of the Municipal Bonds covered by such
Policies. The estimate is based on the expected composition of each Fund's
portfolio of Municipal Bonds. Additional information regarding the Policies is
set forth in Exhibit IV to this Proxy Statement and Prospectus. In instances in
which the Fund purchases Municipal Bonds insured under policies obtained by
parties other than the Fund, the Fund does not pay the premiums for such
policies; rather, the cost of such policies may be reflected in the purchase
price of the Municipal Bonds.
 
     It is the intention of FAM to retain any insured securities which are in
default or in significant risk of default and to place a value on the insurance
which ordinarily will be the difference between the market value of the
defaulted security and the market value of similar securities which are not in
default. In certain circumstances, however, FAM may determine that an
alternative value for the insurance, such as the difference between the market
value of the defaulted security and its par value, is more appropriate. FAM will
be unable to manage the portfolio of a Fund to the extent it holds defaulted
securities, which may limit its ability in certain circumstances to purchase
other Municipal Bonds. See "Net Asset Value" below for a more complete
description of each Fund's method of valuing defaulted securities and securities
which have a significant risk of default.
 
     There can be no assurance that insurance of the kind described above will
continue to be available to each Fund. In the event the Board of Directors of a
Fund determines that such insurance is unavailable or that the cost of such
insurance outweighs the benefits to the Fund, the Fund may discontinue its
policy of maintaining insurance for all or any of the Municipal Bonds held in
the Fund's portfolio. Although FAM periodically
 
                                       31
   36
 
reviews the financial condition of each insurer, there can be no assurance that
the insurers will be able to honor their obligations under all circumstances.
 
     The portfolio insurance reduces financial or credit risk (i.e., the
possibility that the owners of the insured Municipal Bonds will not receive
timely scheduled payments of principal or interest). However, the insured
Municipal Bonds are subject to market risk (i.e., fluctuations in market value
as a result of changes in prevailing interest rates).
 
DESCRIPTION OF MUNICIPAL BONDS
 
     Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction of a wide range of public facilities,
refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of industrial development bonds are issued by or on behalf of
public authorities to finance various privately operated facilities, including
pollution control facilities. For purposes of this Proxy Statement and
Prospectus, such obligations are Municipal Bonds if the interest paid thereon is
exempt from Federal income tax, even though such bonds may be "private activity
bonds" as discussed below.
 
     The two principal classifications of Municipal Bonds are "general
obligation" bonds and "revenue" or "special obligation" bonds. General
obligation bonds are secured by the issuer's pledge of faith, credit and taxing
power for the payment of principal and interest. Revenue or special obligation
bonds are payable only from the revenues derived from a particular facility or
class of facilities or, in some cases, from the proceeds from a special excise
tax or other specific revenue source such as from the user of the facility being
financed. Industrial development bonds are in most cases revenue bonds and
generally do not constitute the pledge of the credit or taxing power of the
issuer of such bonds. The payment of the principal and interest on such
industrial development bonds depends solely on the ability of the user of the
facility financed by the bonds to meet its financial obligations and the pledge,
if any, of real and personal property so financed as security for such payment.
Municipal Bonds also may include "moral obligation" bonds which normally are
issued by special purpose public authorities. If an issuer of moral obligation
bonds is unable to meet its obligations, the repayment of such bonds becomes a
moral commitment but not a legal obligation of the state or municipality in
question.
 
     Each Fund may purchase Municipal Bonds classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities). Interest
received on certain tax-exempt securities which are classified as "private
activity bonds" may subject certain investors in the Fund to an alternative
minimum tax. There is no limitation on the percentage of each Fund's assets that
may be invested in Municipal Bonds which may subject certain investors to an
alternative minimum tax. See "Summary -- Tax Considerations" and "Agreement and
Plan of Reorganization -- Tax Consequences of the Reorganization".
 
     Federal tax legislation has limited the types and volume of bonds the
interest on which qualifies for a Federal income tax exemption. As a result,
this legislation and legislation which may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Funds.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK MUNICIPAL BONDS
 
     Each Fund ordinarily will invest at least 65% of its total assets in New
York Municipal Bonds and, therefore, is more susceptible to factors adversely
affecting issuers of New York Municipal Bonds than is a
 
                                       32
   37
 
municipal bond investment company that is not concentrated in issuers of New
York Municipal Bonds to this degree. As of April 18, 1996, Moody's, S&P and
Fitch rated New York City's general obligation bonds Baa1, BBB+ and A-,
respectively. Moody's, S&P and Fitch currently rate New York State's outstanding
general obligation bonds A, A- and A+, respectively. Because each Fund's
portfolio will comprise investment grade securities, each Fund is expected to be
insulated from the market and credit risks that may exist in connection with
investments in non-investment grade New York Municipal Bonds. See Exhibit
II -- "Economic Conditions in New York".
 
OTHER INVESTMENT POLICIES
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III have adopted certain other policies as set forth below:
 
     Borrowings.  Each Fund is authorized to borrow amounts of up to 5% of the
value of its total assets at the time of such borrowings; provided, however,
that each Fund is authorized to borrow money in excess of 5% of the value of its
total assets for the purpose of repurchasing its Common Stock or redeeming its
AMPS. Borrowings by each Fund create an opportunity for greater total return
but, at the same time, increase exposure to capital risk. In addition, borrowed
funds are subject to interest costs that may offset or exceed the return earned
on the borrowed funds. For so long as shares of a Fund's AMPS are rated by
Moody's or S&P, unless it receives written confirmation from Moody's or S&P, as
the case may be, that such action would not impair the ratings then assigned to
the shares of AMPS by Moody's or S&P, the issuing Fund will not borrow money
except for the purpose of clearing portfolio securities transactions (which
borrowings under any circumstances shall be limited to the lesser of $10 million
and an amount equal to 5% of the market value of the Fund's assets at the time
of such borrowings and further in the case of MuniVest New York Insured and
MuniYield New York Insured III, which borrowings shall be repaid within 60 days
and not be extended or renewed).
 
     When-Issued Securities and Delayed Delivery Transactions.  Each of the
Funds may purchase or sell Municipal Bonds on a delayed delivery basis or on a
when-issued basis at fixed purchase or sale terms. These transactions arise when
securities are purchased or sold by a Fund with payment and delivery taking
place in the future. The purchase will be recorded on the date that the Fund
enters into the commitment, and the value of the obligation thereafter will be
reflected in the calculation of the Fund's net asset value. The value of the
obligation on the delivery day may be more or less than its purchase price. A
separate account of the Fund will be established with its custodian consisting
of cash, cash equivalents or liquid Municipal Bonds having a market value at all
times at least equal to the amount of the forward commitment.
 
     Indexed and Inverse Floating Obligations.  Each of the Funds may invest in
Municipal Bonds the return on which is based on a particular index of value or
interest rates. For example, each Fund may invest in Municipal Bonds that pay
interest based on an index of Municipal Bond interest rates or based on the
value of gold or some other product. The principal amount payable upon maturity
of certain Municipal Bonds also may be based on the value of an index. To the
extent a Fund invests in these types of Municipal Bonds, the Fund's return on
such Municipal Bonds will be subject to risk with respect to the value of the
particular index. Also, a Fund may invest in so-called "inverse floating rate
bonds" or "residual interest bonds" on which the interest rates typically vary
inversely with a short-term floating rate (which may be reset periodically by a
dutch auction, by a remarketing agent, or by reference to a short-term
tax-exempt interest rate index). Each Fund may purchase original issue inverse
floating rate bonds in both the primary and secondary markets and also
 
                                       33
   38
 
may purchase in the secondary market synthetically-created inverse floating rate
bonds evidenced by custodial or trust receipts. Generally, interest rates on
inverse floating rate bonds will decrease when short-term rates increase, and
will increase when short-term rates decrease. Such securities have the effect of
providing a degree of investment leverage, since they may increase or decrease
in value in response to changes, as an illustration, in market interest rates at
a rate which is a multiple (typically two) of the rate at which fixed-rate,
long-term, tax-exempt securities increase or decrease in response to such
changes. As a result, the market values of such securities generally will be
more volatile than the market values of fixed-rate tax-exempt securities. To
seek to limit the volatility of these securities, a Fund may purchase inverse
floating rate bonds with shorter-term maturities or which contain limitations on
the extent to which the interest rate may vary. FAM believes that indexed and
inverse floating obligations represent a flexible portfolio management
instrument for the Funds which allows FAM to vary the degree of investment
leverage relatively efficiently under different market conditions.
 
     Call Rights.  Each of the Funds may purchase a Municipal Bond issuer's
right to call all or a portion of such Municipal Bond for mandatory tender for
purchase (a "Call Right"). A holder of a Call Right may exercise such right to
require a mandatory tender for the purchase of the related Municipal Bonds,
subject to certain conditions. A Call Right that is not exercised prior to the
maturity of the related Municipal Bond will expire without value. The economic
effect of holding both the Call Right and the related Municipal Bond is
identical to holding a Municipal Bond as a non-callable security.
 
INFORMATION REGARDING OPTIONS AND FUTURES TRANSACTIONS
 
     Each Fund may hedge all or a portion of its portfolio investments against
fluctuations in interest rates through the use of options and certain financial
futures contracts ("financial futures contracts") and options thereon. While
each Fund's use of hedging strategies is intended to reduce the volatility of
the net asset value of its Common Stock, the net asset value of its Common Stock
fluctuates. There can be no assurance that a Fund's hedging transactions will be
effective. In addition, because of the leveraged nature of each Fund's Common
Stock, hedging transactions will result in a larger impact on the net asset
value of the Common Stock than would be the case if the Common Stock were not
leveraged. For so long as a Fund's AMPS are rated by Moody's or S&P, as the case
may be, the Fund's use of options and financial futures contracts and options
thereon will be subject to certain limitations mandated by the rating agencies.
Furthermore, a Fund only will engage in hedging activities from time to time and
may not necessarily be engaging in hedging activities when movements in interest
rates occur.
 
     Certain Federal income tax requirements may limit a Fund's ability to
engage in hedging transactions. Gains from transactions in financial futures
contracts or options thereon distributed to stockholders are taxable as ordinary
income or, in certain circumstances, as long-term capital gains to stockholders.
 
     The following is a description of the transactions involving options and
financial futures contracts and options thereon in which each Fund may engage,
limitations on the use of such transactions and risks associated therewith. The
investment policies with respect to the hedging transactions of a Fund are not
fundamental policies and may be modified by the Board of Directors of the Fund
without the approval of the Fund's stockholders.
 
     Writing Covered Call Options.  Each Fund is authorized to write (i.e.,
sell) covered call options with respect to Municipal Bonds it owns, thereby
giving the holder of the option the right to buy the underlying
 
                                       34
   39
 
security covered by the option from the Fund at the stated exercise price until
the option expires. Each Fund writes only covered call options, which means that
so long as the Fund is obligated as the writer of a call option, it will own the
underlying securities subject to the option. The Fund may not write covered call
options on underlying securities in an amount exceeding 15% of the market value
of its total assets. Each Fund receives a premium from writing a call option,
which increases the Fund's return on the underlying security in the event the
option expires unexercised or is closed out at a profit. By writing a call, a
Fund limits its opportunity to profit from an increase in the market value of
the underlying security above the exercise price of the option for as long as
the Fund's obligation as a writer continues. Covered call options serve as a
partial hedge against a decline in the price of the underlying security. Each
Fund may engage in closing transactions in order to terminate outstanding
options that it has written.
 
     Purchase of Options.  Each Fund is authorized to purchase put options in
connection with its hedging activities. By buying a put, the Fund has a right to
sell the underlying security at the exercise price, thus limiting the Fund's
risk of loss through a decline in the market value of the security until the put
expires. The amount of any appreciation in the value of the underlying security
will be partially offset by the amount of the premium terminated by entering
into the closing sale transaction. In certain circumstances, the Fund may
purchase call options on securities held in its portfolio on which it has
written call options, or on securities which it intends to purchase. A Fund will
not purchase options on securities if, as a result of such purchase, the
aggregate cost of all outstanding options on securities held by the Fund would
exceed 5% of the market value of the Fund's total assets.
 
     Financial Futures Contracts and Options Thereon.  Each Fund is authorized
to purchase and sell certain financial futures contracts and options thereon
solely for the purposes of hedging its investments in Municipal Bonds against
declines in value and hedging against increases in the cost of securities it
intends to purchase. A financial futures contract obligates the seller of a
contract to deliver and the purchaser of a contract to take delivery of the type
of financial instrument covered by the contract or, in the case of index-based
financial futures contracts, to make and accept a cash settlement, at a specific
future time for a specified price. A sale of financial futures contracts or
options thereon may provide a hedge against a decline in the value of portfolio
securities because such depreciation may be offset, in whole or in part, by an
increase in the value of the position in the financial futures contracts or
options. A purchase of financial futures contracts or options thereon may
provide a hedge against an increase in the cost of securities intended to be
purchased, because such appreciation may be offset, in whole or in part, by an
increase in the value of the position in the financial futures contracts or
options.
 
     The purchase or sale of a financial futures contract or option thereon
differs from the purchase or sale of a security in that no price or premium is
paid or received. Instead, an amount of cash or securities acceptable to the
broker equal to approximately 5% of the contract amount must be deposited with
the broker. This amount is known as initial margin. Subsequent payments to and
from the broker, called variation margin, are made on a daily basis as the price
of the financial futures contract or option thereon fluctuates making the long
and short positions in the financial futures contract or option thereon more or
less valuable.
 
     Each Fund may purchase and sell financial futures contracts based on The
Bond Buyer Municipal Bond Index, a price-weighted measure of the market value of
40 large tax-exempt issues, and purchase and sell put and call options on such
financial futures contracts for the purpose of hedging Municipal Bonds which the
Fund holds or anticipates purchasing against adverse changes in interest rates.
 
                                       35
   40
 
     Each Fund also may purchase and sell financial futures contracts on U.S.
Government securities and purchase and sell put and call options on such
financial futures contracts for such hedging purposes. With respect to U.S.
Government securities, currently there are financial futures contracts based on
long-term U.S. Treasury bonds, U.S. Treasury notes, GNMA Certificates and
three-month U.S. Treasury bills.
 
     Subject to policies adopted by its Board of Directors, each Fund also may
engage in transactions in other financial futures contracts or options thereon,
such as financial futures contracts or options on other municipal bond indices
which may become available, if FAM should determine that there normally is
sufficient correlation between the prices of such financial futures contracts or
options thereon and the Municipal Bonds in which the Fund invests to make such
hedging appropriate.
 
     Over-The-Counter Options. Each Fund is authorized to engage in transactions
involving financial futures contracts or options thereon on exchanges and in the
over-the-counter markets ("OTC options"). In general, exchange-traded contracts
are third-party contracts (i.e., performance of the parties' obligations is
guaranteed by an exchange or clearing corporation) with standardized strike
prices and expiration dates. OTC options transactions are two-party contracts
with price and terms negotiated by the buyer and seller.
 
     Restrictions on OTC Options. Each Fund is authorized to engage in
transactions in OTC options only with member banks of the Federal Reserve System
and primary dealers in U.S. Government securities or with affiliates of such
banks or dealers which have capital of at least $50 million or whose obligations
are guaranteed by an entity having capital of at least $50 million. OTC options
and assets used to cover OTC options written by the Funds are considered by the
staff of the Commission to be illiquid. The illiquidity of such options or
assets may prevent a successful sale of such options or assets, result in a
delay of sale, or reduce the amount of proceeds that otherwise might be
realized.
 
     Risk Factors in Financial Futures Contracts and Options
Thereon. Utilization of financial futures contracts and options thereon involves
the risk of imperfect correlation in movements in the price of financial futures
contracts and options thereon and movements in the price of the security which
is the subject of the hedge. If the price of the financial futures contract or
option thereon moves more or less than the price of the security that is the
subject of the hedge, a Fund will experience a gain or loss which will not be
completely offset by movements in the price of such security. There is a risk of
imperfect correlation where the securities underlying financial futures
contracts or options thereon have different maturities, ratings, geographic
compositions or other characteristics than the security being hedged. In
addition, the correlation may be affected by additions to or deletions from the
index which serves as a basis for a financial futures contract or option
thereon. Finally, in the case of financial futures contracts on U.S. Government
securities and options on such financial futures contracts, the anticipated
correlation of price movements between the U.S. Government securities underlying
the financial futures contracts or options and Municipal Bonds may be adversely
affected by economic, political, legislative or other developments which have a
disparate impact on the respective markets for such securities.
 
     Under regulations of the Commodity Futures Trading Commission, the futures
trading activities described herein will not result in a Fund's being deemed a
"commodity pool," as defined under such regulations, provided that the Fund
adheres to certain restrictions. In particular, the Fund may purchase and sell
futures contracts and options thereon (i) for bona fide hedging purposes, and
(ii) for non-hedging purposes, if the aggregate initial margin and premiums
required to establish positions in such contracts and options does not exceed 5%
of the liquidation value of the Fund's portfolio, after taking into account
unrealized
 
                                       36
   41
 
profits and unrealized losses on any such contracts and options. Margin deposits
may consist of cash or securities acceptable to the broker and the relevant
contract market.
 
     When a Fund purchases a financial futures contract, or writes a put option
or purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., commercial paper and daily tender adjustable notes) or
short-term, high-grade, fixed-income securities in a segregated account with the
Fund's custodian, so that the amount so segregated plus the amount of initial
and variation margin held in the account of its broker equals the market value
of the financial futures contract, thereby ensuring that the use of such
financial futures contract is unleveraged.
 
     Although certain risks are involved in financial futures contracts and
options thereon, FAM believes that, because each Fund will engage in
transactions involving financial futures contracts and options thereon only for
hedging purposes, the options and futures portfolio strategies of a Fund will
not subject the Fund to certain risks frequently associated with speculation in
financial futures contracts and options thereon. A Fund may be restricted in
engaging in transactions involving financial futures contracts and options
thereon due to the requirement that less than 30% of its gross income in each
taxable year be derived from the sale or other disposition of securities held
for less than three months.
 
     The volume of trading in the exchange markets with respect to Municipal
Bond options may be limited, and it is impossible to predict the amount of
trading interest that may exist in such options. In addition, there can be no
assurance that viable exchange markets will continue.
 
     Each Fund intends to enter into financial futures contracts and options
thereon, on an exchange or in the over-the-counter market, only if there appears
to be a liquid secondary market for such financial futures contracts or options.
There can be no assurance, however, that a liquid secondary market will exist at
any specific time. Thus, it may not be possible to close a financial futures
contract position or the related option. The inability to close financial
futures contract positions or the related options also could have an adverse
impact on a Fund's ability to hedge effectively its portfolio. There is also the
risk of loss by a Fund of margin deposits or collateral in the event of
bankruptcy of a broker with which the Fund has an open position in a financial
futures contract or the related option.
 
     The liquidity of a secondary market in a financial futures contract or
option thereon may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
financial futures contract or option price during a single trading day. Once the
daily limit has been reached in the financial futures contract or option, no
trades may be entered into at a price beyond the limit, thus preventing the
liquidation of open financial futures contract positions or the related options.
Prices in the past have reached or exceeded the daily limit on a number of
consecutive trading days.
 
     If it is not possible to close a financial futures contract position or the
related option entered into by a Fund, the Fund would continue to be required to
make daily cash payments of variation margin in the event of adverse price
movements. In such a situation, if the Fund has insufficient cash, it may have
to sell portfolio securities to meet daily variation margin requirements at a
time when it may be disadvantageous to do so.
 
     The successful use of these transactions also depends on the ability of FAM
to forecast correctly the direction and extent of interest rate movements within
a given time frame. To the extent interest rates remain stable during the period
in which a financial futures contract or option thereon is held by a Fund or
moves in a direction opposite to that anticipated, the Fund may realize a loss
on the hedging transaction which is not fully
 
                                       37
   42
 
or partially offset by an increase in the value of portfolio securities. As a
result, the Fund's total return for such period may be less than if it had not
engaged in the hedging transaction.
 
INVESTMENT RESTRICTIONS
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III have identical investment restrictions. The following are
fundamental investment restrictions of each Fund and may not be changed without
the approval of the holders of a majority of the outstanding shares of Common
Stock and the outstanding shares of AMPS and any other preferred stock, voting
together as a single class, and a majority of the outstanding shares of AMPS and
any other preferred stock, voting separately as a class. (For this purpose and
under the Investment Company Act, "majority" means for each such class the
lesser of (i) 67% of the shares of each class of capital stock represented at a
meeting at which more than 50% of the outstanding shares of each class of
capital stock are represented or (ii) more than 50% of the outstanding shares of
each class of capital stock.) None of the Funds may:
 
          1. Make investments for the purpose of exercising control or
     management.
 
          2. Purchase securities of other investment companies, except in
     connection with a merger, consolidation, acquisition or reorganization, or
     by purchase in the open market of securities of closed-end investment
     companies and only if immediately thereafter not more than 10% of the
     Fund's total assets would be invested in such securities.
 
          3. Purchase or sell real estate, real estate limited partnerships,
     commodities or commodity contracts; provided, however, that the Fund may
     invest in securities secured by real estate or interests therein or issued
     by companies that invest in real estate or interests therein, and the Fund
     may purchase and sell financial futures contracts and options thereon.
 
          4. Issue senior securities other than preferred stock or borrow
     amounts in excess of 5% of its total assets taken at market value;
     provided, however, that the Fund is authorized to borrow moneys in excess
     of 5% of the value of its total assets for the purpose of repurchasing
     shares of Common Stock or redeeming shares of preferred stock.
 
          5. Underwrite securities of other issuers except insofar as the Fund
     may be deemed an underwriter under the Securities Act of 1933 in selling
     portfolio securities.
 
          6. Make loans to other persons, except that the Fund may purchase
     Municipal Bonds and other debt securities in accordance with its investment
     objective, policies and limitations.
 
          7. Purchase any securities on margin, except that the Fund may obtain
     such short-term credit as may be necessary for the clearance of purchases
     and sales of portfolio securities (the deposit or payment by the Fund of
     initial or variation margin in connection with financial futures contracts
     and options thereon is not considered the purchase of a security on
     margin).
 
          8. Make short sales of securities or maintain a short position or
     invest in put, call, straddle or spread options, except that the Fund may
     write, purchase and sell options and futures on Municipal Bonds, U.S.
     Government obligations and related indices or otherwise in connection with
     bona fide hedging activities.
 
                                       38
   43
 
          9. Invest more than 25% of its total assets (taken at market value at
     the time of each investment) in securities of issuers in a single industry;
     provided, however, that for purposes of this restriction, states,
     municipalities and their political subdivisions are not considered to be
     part of any industry.
 
     An additional investment restriction adopted by each Fund, which may be
changed by the Board of Directors, provides that the Fund may not mortgage,
pledge, hypothecate or in any manner transfer, as security for indebtedness, any
securities owned or held by the Fund except as may be necessary in connection
with borrowings mentioned in investment restriction (4) above or except as may
be necessary in connection with transactions in financial futures contracts and
options thereon.
 
     If a percentage restriction on investment policies or the investment or use
of assets set forth above is adhered to at the time a transaction is effected,
later changes in percentage resulting from changing values will not be
considered a violation.
 
RATING AGENCY GUIDELINES
 
     Each Fund intends that, so long as shares of its AMPS are outstanding, the
composition of its portfolio will reflect guidelines established by Moody's and
S&P in connection with the Fund's receipt of a rating for such shares on their
date of original issue of "aaa" from Moody's and AAA from S&P. Moody's and S&P,
nationally recognized statistical rating organizations, issue ratings for
various securities reflecting the perceived creditworthiness of such securities.
The guidelines for rating AMPS have been developed by Moody's and S&P in
connection with issuances of asset-backed and similar securities, including debt
obligations and variable rate preferred stocks, generally on a case-by-case
basis through discussions with the issuers of these securities. The guidelines
are designed to ensure that assets underlying outstanding debt or preferred
stock will be varied sufficiently and will be of sufficient quality and amount
to justify investment-grade ratings. The guidelines do not have the force of law
but have been adopted by each Fund in order to satisfy current requirements
necessary for Moody's and S&P to issue the above-described ratings for shares of
AMPS, which ratings generally are relied upon by institutional investors in
purchasing such securities. The guidelines provide a set of tests for portfolio
composition and asset coverage that supplement (and in some cases are more
restrictive than) the applicable requirements under the Investment Company Act.
 
     Each Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by Moody's or S&P. Failure to adopt
any such modifications, however, may result in a change in the ratings described
above or a withdrawal of the ratings altogether. In addition, any rating agency
providing a rating for the shares of AMPS, at any time, may change or withdraw
any such rating. As set forth in the Articles Supplementary of each Fund, the
Board of Directors, without stockholder approval, may modify certain definitions
or restrictions which have been adopted by the Fund pursuant to the rating
agency guidelines, provided the Board of Directors has obtained written
confirmation from Moody's and S&P that any such change would not impair the
ratings then assigned by Moody's and S&P to the AMPS. See "The
Reorganization -- Risk Factors and Special Considerations -- Ratings
Considerations".
 
     For so long as any shares of a Fund's AMPS are rated by Moody's or S&P, as
the case may be, a Fund's use of options and financial futures contracts and
options thereon will be subject to certain limitations mandated by the rating
agencies.

PORTFOLIO COMPOSITION
 
     Although the investment portfolios of all three Funds must satisfy the same
standards of credit quality, the actual securities owned by each Fund are
different, as a result of which there are certain differences in the composition
of the three investment portfolios. Of the Municipal Bonds owned by MuniVest New
York Insured, as of April 30, 1996, 88% are rated in the highest grade by
Moody's or S&P, 88% are rated in the highest two grades, 88% are rated in the
highest three grades, 100% are rated in the highest four grades, and 0% are
unrated. The comparable percentages for MuniYield New York Insured II are 87% in
the highest grade, 89% in the highest two grades, 89% in the highest three
grades, 100% in the highest four grades and 0% unrated and for MuniYield New
York Insured III are 87% in the highest grade, 92% in the highest two grades,
92% in the highest three grades, 100% in the highest four grades and 0% unrated.
 
     There are small differences in concentration among the categories of
issuers of the Municipal Bonds held in the portfolios of the Funds. For MuniVest
New York Insured, as of April 30, 1996, the highest concentration of Municipal
Bonds was in the Transportation, General Obligation and Water & Sewer Utilities,
accounting for 19%, 19%, and 15% of the Fund's portfolio, respectively; for
MuniYield New York Insured II, the highest concentration was in Transportation,
Hospitals/Healthcare and General Obligation, accounting for 31%, 14% and 13% of
the Fund's portfolio; and for MuniYield New York Insured III, the highest
concentration was in the Transportation, Housing and Hospitals/Healthcare
industries, accounting for 25%, 21% and 15% of the Fund's portfolio.
 
  MuniVest New York Insured
 
     As of April 30, 1996, approximately 91% of the market value of MuniVest New
York Insured's portfolio was invested in long-term municipal obligations and
approximately 9% of the market value of MuniVest New York Insured's portfolio
was invested in short-term municipal obligations. The following table sets forth
certain information with respect to the composition of MuniVest New York
Insured's long-term municipal obligation investment portfolio as of April 30,
1996.

PORTFOLIO TRANSACTIONS
 
     The procedures for engaging in portfolio transactions are the same for
MuniVest New York Insured, MuniYield New York Insured II and MuniYield New York
Insured III. Subject to policies established by the Board of Directors of each
Fund, FAM is primarily responsible for the execution of each Fund's portfolio
transactions. In executing such transactions, FAM seeks to obtain the best
results for each Fund, taking into account such factors as price (including the
applicable brokerage commission or dealer spread), size of order, difficulty of
execution and operational facilities of the firm involved and the firm's risk in
positioning a block of securities. While FAM generally seeks reasonably
competitive commission rates, MuniVest New York
 
                                       41
   46
 
Insured, MuniYield New York Insured II and MuniYield New York Insured III do not
necessarily pay the lowest commission or spread available.
 
     None of the Funds has any obligation to deal with any broker or dealer in
the execution of transactions in portfolio securities. Subject to obtaining the
best price and execution, securities firms which provide supplemental investment
research to FAM, including Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch"), may receive orders for transactions by a Fund. Information so
received will be in addition to, and not in lieu of, the services required to be
performed by FAM under its investment advisory agreements with the Funds, and
the expenses of FAM will not necessarily be reduced as a result of the receipt
of such supplemental information.
 
     The securities in which each Fund primarily invests are traded in the
over-the-counter markets, and each Fund normally deals directly with the dealers
who make markets in the securities involved, except in those circumstances where
better prices and execution are available elsewhere. Under the Investment
Company Act, except as permitted by exemptive order, persons affiliated with a
Fund are prohibited from dealing with the Fund as principals in the purchase and
sale of securities. Since transactions in the over-the-counter markets usually
involve transactions with dealers acting as principals for their own account, a
Fund will not deal with affiliated persons, including Merrill Lynch and its
affiliates, in connection with such transactions, except that pursuant to an
exemptive order obtained by FAM, a Fund may engage in principal transactions
with Merrill Lynch in high quality, short-term, tax-exempt securities. An
affiliated person of a Fund may serve as its broker in over-the-counter
transactions conducted on an agency basis.
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III also may make loans to tax-exempt borrowers in individually
negotiated transactions with the borrower. Because an active trading market may
not exist for such securities, the prices that the Funds may pay for these
securities or receive on their resale may be lower than that for similar
securities with a more liquid market.
 
     The Board of Directors of each Fund has considered the possibility of
recapturing for the benefit of the Funds brokerage commissions, dealer spreads
and other expenses of possible portfolio transactions, such as underwriting
commissions, by conducting portfolio transactions through affiliated entities,
including Merrill Lynch. For example, brokerage commissions received by Merrill
Lynch could be offset against the investment advisory fees paid by the Fund to
FAM. After considering all factors deemed relevant, the Directors made a
determination not to seek such recapture. The Directors will reconsider this
matter from time to time.
 
     Periodic auctions are conducted for the MuniVest New York Insured AMPS, the
MuniYield New York Insured II AMPS and the MuniYield New York Insured III AMPS
by the Auction Agent for the Funds. The auctions require the participation of
one or more broker-dealers, each of whom enters into an agreement with the
Auction Agent. After each auction, the Auction Agent pays a service charge, from
funds provided by the issuing Fund, to each broker-dealer at the annual rate of
 1/4 of 1%, calculated on the basis of the purchase price of shares of the
relevant AMPS placed by such broker-dealer at such auction.
 
PORTFOLIO TURNOVER
 
     Generally, neither MuniVest New York Insured, MuniYield New York Insured II
nor MuniYield New York Insured III purchases securities for short-term trading
profits. However, any of the Funds may dispose of securities without regard to
the time that they have been held when such action, for defensive or other
reasons, appears advisable to FAM. While it is not possible to predict turnover
rates with any certainty,
 
                                       42
   47
 
at present it is anticipated that each Fund's annual portfolio turnover rate,
under normal circumstances, will be less than 100%. (The portfolio turnover rate
is calculated by dividing the lesser of purchases or sales of portfolio
securities for the particular fiscal year by the monthly average of the value of
the portfolio securities owned by a Fund during the particular fiscal year. For
purposes of determining this rate, all securities whose maturities at the time
of acquisition are one year or less are excluded.) The portfolio turnover rate
for each of the years ended October 31, 1995 and 1994 was 192.08% and 74.77%,
respectively, for MuniVest New York Insured, 110.76% and 36.79%, respectively,
for MuniYield New York Insured II and 176.98% and 65.22%, respectively, for
MuniYield New York Insured III.
 
NET ASSET VALUE
 
     The net asset value per share of Common Stock of each Fund is determined as
of 15 minutes after the close of business on the NYSE (generally, 4:00 P.M., New
York time) on each day during which the NYSE is open for trading. For purposes
of determining the net asset value of a share of Common Stock of each Fund, the
value of the securities held by the Fund plus any cash or other assets
(including interest accrued but not yet received) minus all liabilities
(including accrued expenses) and the aggregate liquidation value of the
outstanding shares of AMPS is divided by the total number of shares of Common
Stock outstanding at such time. Expenses, including the fees payable to FAM, are
accrued daily.
 
     The Municipal Bonds in which each Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value, each Fund utilizes the
valuations of portfolio securities furnished by a pricing service approved by
the Board of Directors. The pricing service typically values portfolio
securities at the bid price or the yield equivalent when quotations are readily
available. Municipal Bonds for which quotations are not readily available are
valued at fair market value on a consistent basis as determined by the pricing
service using a matrix system to determine valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of each Fund
under the general supervision of the Board of Directors of the Fund. The Board
of Directors of each Fund has determined in good faith that the use of a pricing
service is a fair method of determining the valuation of portfolio securities.
Obligations with remaining maturities of 60 days or less are valued at amortized
cost, unless this method no longer produces fair valuations. Positions in
futures contracts are valued at closing prices for such contracts established by
the exchange on which they are traded, or if market quotations are not readily
available, are valued at fair value on a consistent basis using methods
determined in good faith by the Board of Directors of each Fund.
 
CAPITAL STOCK
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III each has outstanding both Common Stock and AMPS. MuniVest New
York Insured Common Stock, MuniYield New York Insured II Common Stock and
MuniYield New York Insured III Common Stock all are traded on the NYSE. The
shares of MuniVest New York Insured Common Stock commenced trading on the NYSE
on April 30, 1993. As of April 30, 1996, the net asset value per share of the
MuniVest New York Insured Common Stock was $12.66 and the market price per share
was $11.875. The shares of MuniYield New York Insured II Common Stock commenced
trading on the NYSE on June 26, 1992. As of April 30, 1996, the net asset value
per share of the MuniYield New York Insured II Common Stock was $14.18 and the
market price per share was $13.125. The shares of MuniYield New York Insured III
Common Stock commenced trading on the NYSE on November 27, 1992. As of April 30,
1996, the net asset value per share
 
                                       43
   48
 
of the MuniYield New York Insured III Common Stock was $13.77 and the market
price per share was $12.125.
 
     Each Fund is authorized to issue 200,000,000 shares of capital stock, all
of which shares initially were classified as Common Stock. The Board of
Directors of each Fund is authorized to classify or reclassify any unissued
shares of capital stock by setting or changing the preferences, conversion or
other rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption. In connection with each
Fund's offering of shares of AMPS, MuniVest New York Insured reclassified 1,960
shares of unissued capital stock as AMPS, MuniYield New York Insured II
reclassified 2,800 shares of unissued capital stock as AMPS, and MuniYield New
York Insured III reclassified 1,000 shares of unissued capital stock as AMPS.
 
  Common Stock
 
     Holders of each Fund's Common Stock are entitled to share equally in
dividends declared by the Fund's Board of Directors payable to holders of the
Common Stock and in the net assets of the Fund available for distribution to
holders of the Common Stock after payment of the preferential amounts payable to
holders of any outstanding preferred stock. Holders of a Fund's Common Stock do
not have preemptive or conversion rights and shares of a Fund's Common Stock are
not redeemable. The outstanding shares of Common Stock of each Fund are fully
paid and nonassessable.
 
     So long as any shares of a Fund's AMPS or any other preferred stock are
outstanding, holders of the Fund's Common Stock will not be entitled to receive
any dividends of or other distributions from the Fund unless all accumulated
dividends on outstanding shares of the Fund's AMPS and any other preferred stock
have been paid, and unless asset coverage (as defined in the Investment Company
Act) with respect to such AMPS and any other preferred stock would be at least
200% after giving effect to such distributions.
 
  Preferred Stock
 
     MuniVest New York Insured AMPS, MuniYield New York Insured II AMPS and
MuniYield New York Insured III AMPS are structured identically to each other.
The AMPS of each Fund are shares of preferred stock of the Fund that entitle
their holders to receive dividends when, as and if declared by the Board of
Directors, out of funds legally available therefor, at a rate per annum that may
vary for the successive dividend periods. MuniVest New York Insured AMPS,
MuniYield New York Insured II AMPS and MuniYield New York Insured III AMPS all
have liquidation preferences of $25,000 per share; none of the Fund's AMPS are
traded on any stock exchange or over-the-counter. Each Fund's AMPS can be
purchased at an auction or through broker-dealers who maintain a secondary
market in the AMPS.
 
     Auctions generally have been held and will be held every seven days in the
case of the MuniVest New York Insured AMPS and the MuniYield New York Insured II
AMPS, and every 28 days in the case of the MuniYield New York Insured III AMPS,
unless the applicable Fund elects, subject to certain limitations, to have a
special dividend period. As of the auction held on May 16, 1996, the dividend
rate on the MuniVest New York Insured AMPS was 3.72%; as of the auction held on
May 17, 1996, the dividend rate on the MuniYield New York Insured II AMPS was
3.70%; and as of the auction held on May 22, 1996, the dividend rate on the
MuniYield New York Insured III AMPS was 3.50%.
 
                                       44
   49
 
     Under the Investment Company Act, each Fund is permitted to have
outstanding more than one series of preferred stock as long as no single series
has priority over another series as to the distribution of assets of the Fund or
the payment of dividends. Holders of a Fund's preferred stock do not have
preemptive rights to purchase any shares of AMPS or any other preferred stock
that might be issued. The net asset value per share of a Fund's AMPS equals its
liquidation preference plus accumulated dividends per share.
 
  Certain Provisions of the Charter
 
     Each Fund's Charter includes provisions that could have the effect of
limiting the ability of other entities or persons to acquire control of the Fund
or to change the composition of its Board of Directors and could have the effect
of depriving stockholders of an opportunity to sell their shares at a premium
over prevailing market prices by discouraging a third party from seeking to
obtain control of the Fund. A Director may be removed from office with or
without cause by a vote of the holders of at least 66  2/3% of the votes
entitled to be voted on the matter. A Director elected by the holders of Common
Stock, AMPS and any other preferred stock may be removed only by action of such
holders, and a Director elected by the holders of AMPS and any other preferred
stock may be removed only by action of the holders of AMPS and any other
preferred stock. In addition, the Charter of each Fund requires the affirmative
vote of the holders of at least 66  2/3% of all of the Fund's shares of capital
stock, then entitled to be voted, voting as a single class, to approve, adopt or
authorize the following:
 
     (i)   a merger or consolidation or statutory share exchange of the Fund
        with any other corporation or entity,
 
     (ii)  a sale of all or substantially all of the Fund's assets (other than
        in the regular course of the Fund's investment activities), or
 
     (iii) a liquidation or dissolution of the Fund,
 
unless such action has been approved, adopted or authorized by the affirmative
vote of at least two-thirds of the entire Board of Directors, in which case the
affirmative vote of a majority of all of the votes entitled to be cast by
stockholders of the Fund, voting as a single class, is required. Such approval,
adoption or authorization of the foregoing also would require the favorable vote
of the holders of a majority of the shares of preferred stock entitled to be
voted thereon, including the AMPS, voting as a separate class.
 
     In addition, conversion of a Fund to an open-end investment company would
require an amendment to the Fund's Articles of Incorporation. The amendment
would have to be declared advisable by the Board of Directors prior to its
submission to stockholders. Such an amendment would require the affirmative vote
of the holders of at least 66  2/3% of the Fund's outstanding shares of capital
stock (including the AMPS and any other preferred stock) entitled to be voted on
the matter, voting as a single class (or a majority of such shares if the
amendment was previously approved, adopted or authorized by at least two-thirds
of the entire Board of Directors) and the affirmative vote of a majority of the
votes entitled to be cast by holders of shares of preferred stock (including the
AMPS), voting separately as a class. Such a vote also would satisfy a separate
requirement in the Investment Company Act that the change be approved by the
stockholders. Stockholders of an open-end investment company may require the
company to redeem their shares of common stock at any time (except in certain
circumstances as authorized by or under the Investment Company Act) at their net
asset value, less such redemption charge, if any, as might be in effect at the
time of a redemption. All redemptions will be made in cash. If the Fund is
converted to an open-end investment company, it could be
 
                                       45
   50
 
required to liquidate portfolio securities to meet requests for redemption and
the Common Stock no longer would be listed on a stock exchange. Conversion to an
open-end investment company also would require redemption of all outstanding
shares of preferred stock (including the AMPS) and would require changes in
certain of the Fund's investment policies and restrictions, such as those
relating to the issuance of senior securities, the borrowing of money and the
purchase of illiquid securities.
 
     The Board of Directors of each Fund has determined that the 66 2/3% voting
requirements described above, which are greater than the minimum requirements
under Maryland law or the Investment Company Act, are in the best interests of
stockholders generally. Reference should be made to the Charter of each Fund on
file with the Commission for the full text of these provisions.
 
MANAGEMENT OF THE FUNDS
 
     Directors and Officers.  The Boards of Directors of MuniVest New York
Insured, MuniYield New York Insured II and MuniYield New York Insured III
currently consist of six persons, five of whom are not "interested persons", as
defined in the Investment Company Act, of any of the Funds. The Directors are
responsible for the overall supervision of the operations of MuniVest New York
Insured, MuniYield New York Insured II and MuniYield New York Insured III and
perform the various duties imposed on the directors of investment companies by
the Investment Company Act and under applicable Maryland law. MuniVest New York
Insured, MuniYield New York Insured II and MuniYield New York Insured III have
the same officers. For further information regarding the Directors and officers
of each Fund, see "Election of Directors".
 
     Management and Advisory Arrangements.  FAM serves as the investment adviser
for MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III pursuant to separate investment advisory agreements that,
except for their termination dates, are identical. FAM is an affiliate of MLAM,
and both FAM and MLAM are owned and controlled by ML & Co. FAM provides each
Fund with the same investment advisory and management services. FAM or MLAM acts
as the investment adviser for more than 130 registered investment companies. FAM
also offers portfolio management and portfolio analysis services to individuals
and institutions. As of May 31, 1996, FAM and MLAM had a total of approximately
$208.9 billion in investment company and other portfolio assets under management
(approximately $30.5 billion of which were invested in municipal securities),
including accounts of certain affiliates of FAM. The principal business address
of FAM is 800 Scudders Mill Road, Plainsboro, New Jersey 08536.
 
     Each Fund's investment advisory agreement with FAM provides that, subject
to the direction of the Board of Directors of the Fund, FAM is responsible for
the actual management of the Fund's portfolio. The responsibility for making
decisions to buy, sell or hold a particular security for each Fund rests with
FAM, subject to review by the Board of Directors of the Fund.
 
     FAM provides the portfolio management for MuniVest New York Insured,
MuniYield New York Insured II and MuniYield New York Insured III. Such portfolio
management considers analyses from various sources (including brokerage firms
with which each Fund does business), makes the necessary investment decisions,
and places orders for transactions accordingly. FAM also is responsible for the
performance of certain administrative and management services for each Fund.
 
     For the services provided by FAM under each Fund's investment advisory
agreement, the Fund pays a monthly fee at an annual rate of .50 of 1% of the
Fund's average weekly net assets (i.e., the average weekly
 
                                       46
   51
 
value of the total assets of the Fund, minus the sum of accrued liabilities of
the Fund and accumulated dividends on its shares of AMPS). For purposes of this
calculation, average weekly net assets are determined at the end of each month
on the basis of the average net assets of the Fund for each week during the
month. The assets for each weekly period are determined by averaging the net
assets at the last business day of a week with the net assets at the last
business day of the prior week.
 
     Each Fund's investment advisory agreement obligates FAM to provide
investment advisory services and to pay all compensation of and furnish office
space for officers and employees of the Fund connected with investment and
economic research, trading and investment management of the Fund, as well as the
compensation of all Directors of the Fund who are affiliated persons of FAM or
any of its affiliates. Each Fund pays all other expenses incurred in the
operation of the Fund, including, among other things, expenses for legal and
auditing services, taxes, costs of printing proxies, listing fees, stock
certificates and stockholder reports, charges of the custodian and the transfer
agent, dividend disbursing agent and registrar, fees and expenses with respect
to the issuance of AMPS, Commission fees, fees and expenses of unaffiliated
Directors, accounting and pricing costs, insurance, interest, brokerage costs,
litigation and other extraordinary or non-recurring expenses, mailing and other
expenses properly payable by the Fund. FAM provides accounting services to each
Fund, and each Fund reimburses FAM for its respective costs in connection with
such services.
 
     Unless earlier terminated as described below, the investment advisory
agreement between MuniVest New York Insured and FAM will continue from year to
year if approved annually (a) by the Board of Directors of MuniVest New York
Insured or by a majority of the outstanding shares of MuniVest New York Insured
Common Stock and MuniVest New York Insured AMPS, voting together as a single
class, and (b) by a majority of the Directors of MuniVest New York Insured who
are not parties to such contract or "interested persons", as defined in the
Investment Company Act, of any such party. The contract is not assignable and it
may be terminated without penalty on 60 days' written notice at the option of
either party thereto or by the vote of the stockholders of MuniVest New York
Insured.
 
     Similarly, unless earlier terminated as described below, the investment
advisory agreement between MuniYield New York Insured II and FAM will continue
from year to year if approved annually (a) by the Board of Directors of
MuniYield New York Insured II or by a majority of the outstanding shares of
MuniYield New York Insured II Common Stock and MuniYield New York Insured II
AMPS, voting together as a single class, and (b) by a majority of the Directors
of MuniYield New York Insured II who are not parties to such contract or
"interested persons" of any such party. The contract is not assignable and it
may be terminated without penalty on 60 days' written notice at the option of
either party thereto or by the vote of the stockholders of MuniYield New York
Insured II.
 
     Similarly, unless earlier terminated as described below, the investment
advisory agreement between MuniYield New York Insured III and FAM will continue
from year to year if approved annually (a) by the Board of Directors of
MuniYield New York Insured III or by a majority of the outstanding shares of
MuniYield New York Insured III Common Stock and MuniYield New York Insured III
AMPS, voting together as a single class, and (b) by a majority of the Directors
of MuniYield New York Insured III who are not parties to such contract or
"interested persons" of any such party. The contract is not assignable and it
may be terminated without penalty on 60 days' written notice at the option of
either party thereto or by the vote of the stockholders of MuniYield New York
Insured III.

VOTING RIGHTS
 
     Voting rights are identical for the holders of shares of MuniVest New York
Insured Common Stock, MuniYield New York Insured II Common Stock and MuniYield
New York Insured III Common Stock. Holders of each Fund's Common Stock are
entitled to one vote for each share held and will vote with the holders of any
outstanding shares of the Fund's AMPS or other preferred stock on each matter
submitted to a vote of holders of Common Stock, except as set forth below.
 
     Stockholders of each Fund are entitled to one vote for each share held. The
shares of each Fund's Common Stock, AMPS and any other preferred stock do not
have cumulative voting rights, which means that the holders of more than 50% of
the shares of a Fund's Common Stock, AMPS and any other preferred stock voting
for the election of Directors can elect all of the Directors standing for
election by such holders, and, in such event, the holders of the remaining
shares of a Fund's Common Stock, AMPS and any other preferred stock will not be
able to elect any of such Directors.
 
     Voting rights of the holders of MuniVest New York Insured AMPS, MuniYield
New York Insured II AMPS and MuniYield New York Insured III AMPS are identical.
Except as otherwise indicated below, and except as otherwise required by
applicable law, holders of shares of a Fund's AMPS will be entitled to one vote
per share on each matter submitted to a vote of the Fund's stockholders and will
vote together with the holders of shares of the Fund's Common Stock as a single
class.
 
     In connection with the election of a Fund's Directors, holders of shares of
a Fund's AMPS and any other preferred stock, voting separately as a class, shall
be entitled at all times to elect two of the Fund's Directors, and the remaining
Directors will be elected by holders of shares of the Fund's Common Stock and
shares of the Fund's AMPS and any other preferred stock, voting together as a
single class. In addition, if at any time dividends on outstanding shares of a
Fund's AMPS shall be unpaid in an amount equal to at least two full years'
dividends thereon or if at any time holders of any shares of a Fund's preferred
stock are entitled, together with the holders of shares of the Fund's AMPS, to
elect a majority of the Directors of the Fund under the Investment Company Act,
then the number of Directors constituting the Board of Directors automatically
shall be increased by the smallest number that, when added to the two Directors
elected exclusively by the holders of shares of AMPS and any other preferred
stock as described above, would constitute a majority of the Board of Directors
as so increased by such smallest number, and at a special meeting of
stockholders which will be called and held as soon as practicable, and at all
subsequent meetings at which Directors are to be elected, the holders of shares
of the Fund's AMPS and any other preferred stock, voting separately as a class,
will be entitled to elect the smallest number of additional Directors that,
together with the two Directors which such holders in any event will be entitled
to elect, constitutes a majority of the total number of Directors of the Fund as
so increased. The terms of office of the persons who are Directors at the time
of that election will continue. If the Fund thereafter shall pay, or declare and
set apart for payment in full, all dividends payable on all outstanding shares
of AMPS and any other preferred stock for all past dividend periods, the
additional voting rights of the holders of shares of AMPS and any other
preferred stock as described above shall cease, and the terms of office of all
of the additional Directors elected by the holders of shares of AMPS and any
other preferred stock (but not of the Directors with respect to whose election
the holders of shares of Common Stock were entitled to vote or the two Directors
the holders of shares of AMPS and any other preferred stock have the right to
elect in any event) will terminate automatically.

STOCKHOLDER INQUIRIES
 
     Stockholder inquiries with respect to MuniVest New York Insured, MuniYield
New York Insured II and MuniYield New York Insured III may be addressed to any
of the Funds by telephone at (609) 282-2800 or at the address set forth on the
cover page of this Proxy Statement and Prospectus.
 
DIVIDENDS AND DISTRIBUTIONS
 
     The Funds' current policies with respect to dividends and distributions
relating to shares of their Common Stock are identical. Each Fund intends to
distribute all of its net investment income. Dividends from such net investment
income are declared and paid monthly to holders of a Fund's Common Stock.
Monthly distributions to holders of a Fund's Common Stock normally consist of
substantially all of the net investment income remaining after the payment of
dividends on the Fund's AMPS. All net realized long-term or short-term capital
gains, if any, are distributed at least annually, pro rata to holders of shares
of a Fund's Common Stock and AMPS. While any shares of a Fund's AMPS are
outstanding, the Fund may not declare any cash dividend or other distribution on
the Fund's Common Stock, unless at the time of such declaration (1) all
accumulated dividends on the Fund's AMPS have been paid, and (2) the net asset
value of the Fund's portfolio (determined after deducting the amount of such
dividend or other distribution) is at least 200% of the liquidation value of the
Fund's outstanding shares of AMPS. This limitation on a Fund's ability to make
distributions on its Common Stock under certain circumstances could impair the
ability of the Fund to maintain its qualification for taxation as a RIC. See
"Agreement and Plan of Reorganization -- Tax Consequences of the
Reorganization".
 
     Similarly, the Funds' current policies with respect to dividends and
distributions relating to shares of their AMPS are identical. The holders of
shares of a Fund's AMPS are entitled to receive, when, as and if declared by the
Board of Directors of the Fund, out of funds legally available therefor,
cumulative cash dividends on their shares. Dividends on a Fund's shares of AMPS
so declared and payable shall be paid (i) in preference to and in priority over
any dividends so declared and payable on the Fund's Common Stock, and (ii) to
the extent permitted under the Code and to the extent available, out of net
tax-exempt income earned on the Fund's investments. Dividends for the MuniVest
New York Insured AMPS, the MuniYield New York Insured II AMPS and the MuniYield
New York Insured III AMPS are paid through The Depository Trust Company ("DTC")
(or a successor securities depository) on each dividend payment date. DTC's
normal procedures now provide for it to distribute dividends in same-day funds
to agent members, who in turn are expected to distribute such dividends to the
person for whom they are acting as agent in accordance with the instructions of
such person. Prior to each dividend payment date, the relevant Fund is required
to deposit with the Auction Agent sufficient funds for the payment of such
declared dividends. None of the Funds intends to establish any reserves for the
payment of dividends, and no interest will be payable in respect of any dividend
payment or payment on the shares of a Fund's AMPS which may be in arrears.
 
     Dividends paid by each Fund, to the extent paid from tax-exempt income
earned on New York Municipal Bonds, are exempt from Federal, New York State and
New York City income taxes, subject to the possible application of the
alternative minimum tax. However, each Fund is required to allocate net capital
gains and other income subject to regular Federal, New York State and New York
City income taxes, if any, proportionately between shares of its Common Stock
and shares of its AMPS in accordance with the current position of the IRS
described herein. Each Fund notifies the Auction Agent of the amount of any net
capital gains or other taxable income to be included in any dividend on shares
of AMPS prior to the auction
 
                                       49
   54
 
establishing the applicable rate for such dividend. The Auction Agent in turn
notifies each broker-dealer whenever it receives any such notice from a Fund,
and each broker-dealer then notifies its customers who are holders of the Fund's
AMPS. Each Fund also may include such income in a dividend on shares of its AMPS
without giving advance notice thereof if it increases the dividend by an
additional amount to offset the tax effect thereof. The amount of taxable income
allocable to shares of a Fund's AMPS will depend upon the amount of such income
realized by the Fund and other factors, but generally is not expected to be
significant.
 
     For information concerning the manner in which dividends and distributions
to holders of each Fund's Common Stock may be reinvested automatically in shares
of the Fund's Common Stock, see "Automatic Dividend Reinvestment Plan" below.
Dividends and distributions may be taxable to stockholders under certain
circumstances as discussed below, whether they are reinvested in shares of a
Fund or received in cash.
 
     If MuniVest New York Insured, MuniYield New York Insured II or MuniYield
New York Insured III, as the case may be, retroactively allocates any net
capital gains or other income subject to regular Federal, New York State and New
York City income taxes to shares of its AMPS without having given advance notice
thereof as described above, which only may happen when such allocation is made
as a result of the redemption of all or a portion of the outstanding shares of
its AMPS or the liquidation of the Fund, the Fund will make certain payments to
holders of shares of its AMPS to which such allocation was made to offset
substantially the tax effect thereof. In no other instances will the Fund be
required to make payments to holders of shares of its AMPS to offset the tax
effect of any reallocation of net capital gains or other taxable income.
 
AUTOMATIC DIVIDEND REINVESTMENT PLAN
 
     Pursuant to each Fund's Automatic Dividend Reinvestment Plan (each, the
"Plan"), unless a holder of a Fund's Common Stock elects otherwise, all dividend
and capital gains distributions are reinvested automatically by either The Bank
of New York or Boston EquiServe, as applicable, as agent for stockholders in
administering the Plan (as applicable, the "Plan Agent"), in additional shares
of the Fund's Common Stock. Holders of a Fund's Common Stock who elect not to
participate in the Plan receive all distributions in cash paid by check mailed
directly to the stockholder of record (or, if the shares are held in street or
other nominee name, then to such nominee) by The Bank of New York or Boston
EquiServe, as applicable, as dividend paying agent. Such stockholders may elect
not to participate in the Plan and to receive all distributions of dividends and
capital gains in cash by sending written instructions to The Bank of New York or
Boston EquiServe, as applicable, as dividend paying agent, at the address set
forth below. Participation in the Plan is completely voluntary and may be
terminated or resumed at any time without penalty by written notice if received
by the Plan Agent not less than ten days prior to any dividend record date;
otherwise, such termination will be effective with respect to any subsequently
declared dividend or capital gains distribution.
 
     Whenever a Fund declares an ordinary income dividend or a capital gain
dividend (collectively referred to as "dividends") payable either in shares or
in cash, non-participants in the Plan receive cash, and participants in the Plan
receive the equivalent in shares of the Fund's Common Stock. The shares are
acquired by the Plan Agent for the participant's account, depending upon the
circumstances described below, either (i) through receipt of additional unissued
but authorized shares of the Fund's Common Stock from the Fund ("newly-issued
shares") or (ii) by purchase of outstanding shares of the Fund's Common Stock on
the open market ("open-market purchases"), on the NYSE or elsewhere. If on the
payment date for the dividend, the net asset value per share of the Fund's
Common Stock is equal to or less than the market price per share of the Fund's
Common Stock plus estimated brokerage commissions (such condition being referred
to herein as
 
                                       50
   55
 
"market premium"), the Plan Agent invests the dividend amount in newly-issued
shares on behalf of the participant. The number of newly-issued shares of the
Fund's Common Stock to be credited to the participant's account is determined by
dividing the dollar amount of the dividend by the net asset value per share on
the date the shares are issued, provided that the maximum discount from the then
current market price per share on the date of issuance may not exceed 5%. If on
the dividend payment date, the net asset value per share is greater than the
market value (such condition being referred to herein as "market discount"), the
Plan Agent invests the dividend amount in shares acquired on behalf of the
participant in open-market purchases.
 
     In the event of a market discount on the dividend payment date, the Plan
Agent has until the last business day before the next date on which the shares
trade on an "ex-dividend" basis or in no event more than 30 days after the
dividend payment date (the "last purchase date") to invest the dividend amount
in shares acquired in open-market purchases. Each Fund intends to pay monthly
income dividends. Therefore, the period during which open-market purchases can
be made exists only from the payment date on the dividend through the date
before the next "ex-dividend" date, which typically is approximately ten days.
If, before the Plan Agent has completed its open-market purchases, the market
price of a share of a Fund's Common Stock exceeds the net asset value per share,
the average per share purchase price paid by the Plan Agent may exceed the net
asset value of the Fund's shares, resulting in the acquisition of fewer shares
than if the dividend had been paid in newly-issued shares on the dividend
payment date. Because of the foregoing difficulty with respect to open-market
purchases, the Plan provides that if the Plan Agent is unable to invest the full
dividend amount in open-market purchases during the purchase period or if the
market discount shifts to a market premium during the purchase period, the Plan
Agent ceases making open-market purchases and invests the uninvested portion of
the dividend amount in newly-issued shares at the close of business on the last
purchase date.
 
     The Plan Agent maintains all stockholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account, including
information needed by stockholders for tax records. Shares in the account of
each Plan participant are held by the Plan Agent in non-certificated form in the
name of the participant, and each stockholder's proxy includes those shares
purchased or received pursuant to the Plan. The Plan Agent will forward all
proxy solicitation materials to participants and vote proxies for shares held
pursuant to the Plan in accordance with the instructions of the participants.
 
     In the case of stockholders such as banks, brokers or nominees which hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
record stockholders as representing the total amount registered in the record
stockholder's name and held for the account of beneficial owners who are to
participate in the Plan.
 
     There are no brokerage charges with respect to shares issued directly by
MuniVest New York Insured, MuniYield New York Insured II or MuniYield New York
Insured III as a result of dividends or capital gains distributions payable
either in shares or in cash. However, each participant pays a pro rata share of
brokerage commissions incurred with respect to the Plan Agent's open-market
purchases in connection with the reinvestment of dividends.
 
     The automatic reinvestment of dividends and distributions does not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends. See "Agreement and Plan of
Reorganization -- Tax Consequences of the Reorganization".
 
                                       51
   56
 
     Stockholders participating in the Plan may receive benefits not available
to stockholders not participating in the Plan. If the market price plus
commissions of a Fund's shares of Common Stock is above the net asset value,
participants in the Plan receive shares of the Fund's Common Stock at less than
they otherwise could purchase them and have shares with a cash value greater
than the value of any cash distribution they would have received on their
shares. If the market price plus commissions is below the net asset value,
participants receive distributions in shares with a net asset value greater than
the value of any cash distribution they would have received on their shares.
However, there may be insufficient shares available in the market to make
distributions in shares at prices below the net asset value. Also, since none of
the Funds normally redeems its shares, the price on resale may be more or less
than the net asset value.
 
     Each Fund reserves the right to amend or terminate its Plan. There is no
direct service charge to participants in the Plan; however, each Fund reserves
the right to amend its Plan to include a service charge payable by the
participants.
 
LIQUIDATION RIGHTS OF HOLDERS OF AMPS
 
     Upon any liquidation, dissolution or winding up of MuniVest New York
Insured, MuniYield New York Insured II or MuniYield New York Insured III, as the
case may be, whether voluntary or involuntary, the holders of shares of the
Fund's AMPS will be entitled to receive, out of the assets of the Fund available
for distribution to stockholders, before any distribution or payment is made
upon any shares of the Fund's Common Stock or any other capital stock of the
Fund ranking junior in right of payment upon liquidation to AMPS, $25,000 per
share together with the amount of any dividends accumulated but unpaid (whether
or not earned or declared) thereon to the date of distribution, and after such
payment the holders of AMPS will be entitled to no other payments except for any
additional dividends. If such assets of the Fund shall be insufficient to make
the full liquidation payment on the AMPS and liquidation payments on any other
outstanding class or series of preferred stock of the Fund ranking on a parity
with the AMPS as to payment upon liquidation, then such assets will be
distributed among the holders of shares of AMPS and the holders of shares of
such other class or series ratably in proportion to the respective preferential
amounts to which they are entitled. After payment of the full amount of
liquidation distribution to which they are entitled, the holders of shares of a
Fund's AMPS will not be entitled to any further participation in any
distribution of assets by the Fund except for any additional dividends. A
consolidation, merger or share exchange of a Fund with or into any other entity
or entities or a sale, whether for cash, shares of stock, securities or
properties, of all or substantially all or any part of the assets of the Fund
shall not be deemed or construed to be a liquidation, dissolution or winding up
of the Fund.
 
TAX RULES APPLICABLE TO MUNIVEST NEW YORK INSURED, MUNIYIELD NEW YORK INSURED
II, MUNIYIELD NEW YORK INSURED III AND THEIR STOCKHOLDERS
 
     The tax consequences associated with investment in shares of MuniVest New
York Insured Common Stock, MuniYield New York Insured II Common Stock and
MuniYield New York Insured III Common Stock are identical. Similarly, the tax
consequences associated with investment in shares of MuniVest New York Insured
AMPS, MuniYield New York Insured II AMPS and MuniYield New York Insured III AMPS
are identical. Each of the Funds has elected and qualified for the special tax
treatment afforded RICs under the Code. As a result, in any taxable year in
which they distribute an amount equal to at least 90% of taxable net income and
90% of tax-exempt net income (see below), the Funds (but not their stockholders)
are not subject to Federal income tax to the extent that they distribute their
net investment income and net
 
                                       52
   57
 
realized capital gains. In prior taxable years and in the taxable year of the
Reorganization, each Fund has distributed substantially all of its income.
MuniYield New York Insured II intends to continue to distribute substantially
all of its income in the taxable years following the Reorganization. If, at any
time when shares of a Fund's AMPS are outstanding the Fund does not meet the
asset coverage requirements of the Investment Company Act, the Fund is required
to suspend distributions to holders of shares of its Common Stock until the
asset coverage is restored. This can prevent the Fund from distributing at least
90% of its net income and therefore can jeopardize the Fund's qualification for
taxation as a RIC. Upon any failure to meet the asset coverage requirements, the
Funds may, and under certain circumstances are required to, redeem shares of
AMPS in order to maintain or restore the requisite asset coverage and avoid the
adverse consequences of failing to qualify as a RIC.
 
     Each Fund is qualified to pay "exempt-interest dividends" as defined in
Section 852(b)(5) of the Code. Under such section, if, at the close of each
quarter of its taxable year, at least 50% of the value of a Fund's total assets
consists of obligations exempt from Federal income tax ("tax-exempt
obligations") under Section 103(a) of the Code (relating generally to
obligations of a state or local governmental unit), the Fund is qualified to pay
exempt-interest dividends to its stockholders. Exempt-interest dividends are
dividends or any part thereof paid by a Fund which are attributable to interest
on tax-exempt obligations and designated by the Fund as exempt-interest
dividends in a written notice mailed to stockholders within 60 days after the
close of its taxable year. To the extent that the dividends distributed to a
Fund's stockholders are derived from interest income exempt from Federal income
tax under Code Section 103(a) and are properly designated as exempt-interest
dividends, they are excludable from a stockholder's gross income for Federal
income tax purposes. Exempt-interest dividends are included, however, in
determining the portion, if any, of a person's social security benefits and
railroad retirement benefits subject to Federal income taxes. Interest on
indebtedness incurred or continued to purchase or carry a Fund's shares is not
deductible for Federal income tax purposes to the extent attributable to
exempt-interest dividends. A tax adviser should be consulted with respect to
whether exempt-interest dividends retain the exclusion under Code Section 103(a)
if a stockholder would be treated as a "substantial user" or "related person"
under Code Section 147(a) with respect to property financed with the proceeds
from an issue of "industrial development bonds" or "private activity bonds," if
any, held by a Fund.
 
     Each Fund informs its stockholders annually as to the portion of the Fund's
distributions which constitutes exempt-interest dividends. Interest on
indebtedness incurred or continued to purchase or carry a Fund's shares is not
deductible for Federal, New York State or New York City income tax purposes.
 
     The IRS, in a revenue ruling, held that certain AMPS would be treated as
stock for Federal income tax purposes. The terms of the MuniVest New York
Insured AMPS, the MuniYield New York Insured II AMPS and the MuniYield New York
Insured III AMPS are substantially similar, but not identical, to the AMPS
discussed in the revenue ruling, and in the opinion of Brown & Wood LLP, counsel
to all three Funds, the shares of each Fund's AMPS constitute stock and
distributions with respect to shares of such AMPS (other than distributions in
redemption of shares of AMPS subject to Section 302(b) of the Code) constitute
dividends to the extent of current and accumulated earnings and profits as
calculated for Federal income tax purposes. Nevertheless, the IRS could take a
contrary position, asserting, for example, that the shares of AMPS constitute
debt. If this position were upheld, the discussion of the treatment of
distributions below would not apply to holders of shares of AMPS. Instead,
distributions by each Fund to holders of shares of its AMPS would constitute
interest, whether or not they exceed the earnings and profits of the Fund, would
be included
 
                                       53
   58
 
in full in the income of the recipient and taxed as ordinary income. Counsel
believes that such a position, if asserted by the IRS, would be unlikely to
prevail.
 
     To the extent that a Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends"), such distributions are
considered taxable ordinary income for Federal, New York State and New York City
income tax purposes. Distributions, if any, from an excess of net long-term
capital gains over net short-term capital losses derived from the sale of
securities or from certain transactions in futures or options ("capital gain
dividends") are taxable as long-term capital gains for Federal income tax
purposes, regardless of the length of time the stockholder has owned Fund
shares, and are taxable as ordinary income for New York State and New York City
tax purposes. Distributions by a Fund, whether from exempt-interest income,
ordinary income or capital gains, will not be eligible for the dividends
received deduction for corporations under the Code.
 
     All or a portion of a Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary income
dividends received by stockholders. Any loss upon the sale or exchange of Fund
shares held for six months or less is treated as long-term capital loss to the
extent of capital gain dividends received by the stockholder. In addition, such
loss is disallowed to the extent of any exempt-interest dividends received by
the stockholder. Distributions in excess of a Fund's earnings and profits first
will reduce the adjusted tax basis of a holder's shares and, after such adjusted
tax basis is reduced to zero, will constitute capital gains to such holder
(assuming the shares are held as a capital asset). If a Fund pays a dividend in
January which was declared in the previous October, November or December to
stockholders of record on a specified date in one of such months, then such
dividend is treated for tax purposes as paid by the Fund and received by its
stockholders on December 31 of the year in which such dividend was declared.
 
     The IRS has taken the position in a revenue ruling that if a RIC has two
classes of shares it may designate distributions made to each class in any year
as consisting of no more than such class' proportionate share of particular
types of income, including exempt-interest dividends and capital gain dividends.
Thus, each Fund is required to allocate a portion of its net capital gains and
other taxable income to the shares of its AMPS. Each Fund may notify the Auction
Agent of the amount of any net capital gains and other taxable income to be
included in any dividend on shares of its AMPS prior to the auction establishing
the applicable rate for such dividend. Except for the portion of any dividend
that a Fund informs the Auction Agent will be treated as capital gains or other
taxable income, the dividends paid on the shares of AMPS constitute exempt-
interest dividends. Alternatively, each Fund may include such income in a
dividend on shares of its AMPS without giving advance notice thereof if it
increases the dividend by an additional amount to offset the tax effect thereof.
The amount of net capital gains and ordinary income allocable to shares of a
Fund's AMPS (the "taxable distribution") depends upon the amount of such gains
and income realized by the Fund and the total dividends paid by the Fund on
shares of its Common Stock and shares of its AMPS during a taxable year, but the
taxable distribution generally is not significant.
 
     In the opinion of Brown & Wood LLP, counsel to all three Funds, under
current law the manner in which each Fund allocates items of tax-exempt income,
net capital gains, and other taxable income, if any, between shares of its
Common Stock and shares of its AMPS will be respected for Federal income tax
purposes. However, the tax treatment of additional dividends may affect a Fund's
calculation of each class' allocable share of capital gains and other taxable
income. In addition, there is currently no direct guidance from the IRS or other
sources specifically addressing whether a Fund's method for allocating
tax-exempt income, net capital
 
                                       54
   59
 
gains and other taxable income between shares of its Common Stock and shares of
its AMPS will be respected for Federal income tax purposes, and it is possible
that the IRS could disagree with counsel's opinion and attempt to reallocate a
Fund's net capital gains or other taxable income. In the event of a
reallocation, some of the dividends identified by a Fund as exempt-interest
dividends to holders of shares of its AMPS could be recharacterized as
additional capital gains or other taxable income. In the event of such
recharacterization, a Fund is not required to make payments to such stockholders
to offset the tax effect of such reallocation. In addition, a reallocation could
cause a Fund to be liable for income tax and excise tax on any reallocated
taxable income. Brown & Wood LLP has advised each Fund that, in its opinion, if
the IRS were to challenge in court the Fund's allocations of income and gain,
the IRS would be unlikely to prevail. The opinion of Brown & Wood LLP, however,
represents only its best legal judgment and is not binding on the IRS or the
courts.
 
     The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
it does not distribute 98% of its ordinary income, determined on a calendar year
basis, and 98% of its capital gains, determined in general, on an October 31
year-end, plus certain undistributed amounts from previous years. The required
distributions, however, are based only on the taxable income of a regulated
investment company. The excise tax, therefore, generally does not apply to the
tax-exempt income of RICs, such as the Funds, that pay exempt-interest
dividends.
 
     The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies to
interest received on "private activity bonds" issued after August 7, 1986.
"Private activity bonds" are bonds which, although tax-exempt, are used for
purposes other than those generally performed by governmental units and which
benefit non-governmental entities (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item of
"tax preference" which could subject investors in such bonds, including
stockholders of the Funds, to an increased alternative minimum tax. Each Fund
purchases such "private activity bonds" and reports to stockholders within 60
days after its fiscal year-end the portion of its dividends declared during the
year which constitutes an item of tax preference for alternative minimum tax
purposes. The Code further provides that corporations are subject to an
alternative minimum tax based, in part, on certain differences between taxable
income as adjusted for other tax preferences and the corporation's "adjusted
current earnings" which more closely reflect a corporation's economic income.
Because an exempt-interest dividend paid by a Fund is included in adjusted
current earnings, a corporate stockholder may be required to pay an alternative
minimum tax on exempt-interest dividends paid by such Fund.
 
     Under certain provisions of the Code, some stockholders may be subject to a
31% withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
stockholders subject to backup withholding will be those for whom no taxpayer
identification number is on file with a Fund or who, to the Fund's knowledge,
have furnished an incorrect number. When establishing an account, an investor
must certify under penalty of perjury that such number is correct and that such
stockholder is not otherwise subject to backup withholding.
 
     Ordinary income dividends paid to stockholders who are nonresident aliens
or foreign entities are subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under applicable treaty law.
 
                                       55
   60
 
     A loss realized on a sale or exchange of shares of a Fund is disallowed if
other Fund shares are acquired (whether under the Automatic Dividend
Reinvestment Plan or otherwise) within a 61-day period beginning 30 days before
and ending 30 days after the date that the shares are disposed of. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss.
 
     The Code provides that every stockholder required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Funds) during the taxable
year.
 
AGREEMENT AND PLAN OF REORGANIZATION
 
GENERAL
 
     Under the Agreement and Plan of Reorganization (attached hereto as Exhibit
I), (i) MuniYield New York Insured II will acquire all of the assets, and will
assume all of the liabilities, of MuniVest New York Insured, in exchange solely
for an equal aggregate value of MuniYield New York Insured II Common Stock and
MuniYield New York Insured II Series B AMPS to be issued by MuniYield New York
Insured II; and (ii) MuniYield New York Insured II will acquire all of the
assets, and will assume all of the liabilities, of MuniYield New York Insured
III, in exchange solely for an equal aggregate value of MuniYield New York
Insured II Common Stock and MuniYield New York Insured II Series C AMPS to be
issued by MuniYield New York Insured II. Upon receipt by MuniVest New York
Insured and MuniYield New York Insured III of such shares, MuniVest New York
Insured and MuniYield New York Insured III will distribute the shares of
MuniYield New York Insured II Common Stock to the holders of MuniVest New York
Insured Common Stock and MuniYield New York Insured III Common Stock, the shares
of MuniYield New York Insured II Series B AMPS to the holders of MuniVest New
York Insured AMPS and the shares of MuniYield New York Insured II Series C AMPS
to the holders of MuniYield New York Insured III AMPS in exchange for their
shares in MuniVest New York Insured and MuniYield New York Insured III. Separate
Articles of Amendment to the Articles Supplementary establishing the powers,
rights and preferences of the MuniYield New York Insured II AMPS, redesignating
the currently outstanding MuniYield Insured II AMPS as Series A AMPS, and
separate Articles Supplementary to the Articles of Incorporation of MuniYield
New York Insured II establishing the powers, rights and preferences of the
MuniYield New York Insured II Series B AMPS and the MuniYield New York Insured
II Series C AMPS each will have been filed with the State Department of
Assessments and Taxation of Maryland (the "Maryland Department") prior to the
closing of the Reorganization. As soon as practicable after the date that the
Reorganization takes place (the "Exchange Date"), each of MuniVest New York
Insured and MuniYield New York Insured III will file Articles of Dissolution
with the Maryland Department to effect the formal dissolution of such Funds, and
will dissolve.
 
     MuniVest New York Insured and MuniYield New York Insured III will each
distribute the shares of MuniYield New York Insured II Common Stock, MuniYield
New York Insured II Series B AMPS and MuniYield New York Insured II Series C
AMPS received by it pro rata to its holders of record of MuniVest New York
Insured Common Stock, MuniYield New York Insured III Common Stock, MuniVest New
York Insured AMPS and MuniYield New York Insured III AMPS, respectively, in
exchange for such stockholders' shares in MuniVest New York Insured and
MuniYield New York Insured III. Such distribution would be accomplished by
opening new accounts on the books of MuniYield New York Insured II in the names
of the common and preferred stockholders of MuniVest New York Insured and
MuniYield New York Insured III and transferring to those stockholder accounts
the MuniYield New York Insured II Common Stock,
 
                                       56
   61
 
MuniYield New York Insured II Series B AMPS and MuniYield New York Insured II
Series C AMPS previously credited on those books to the account of MuniVest New
York Insured and MuniYield New York Insured III. Each newly-opened account on
the books of MuniYield New York Insured II for the previous holders of MuniVest
New York Insured Common Stock and MuniYield New York Insured III Common Stock
would represent the respective pro rata number of shares of MuniYield New York
Insured II Common Stock (rounded down, in the case of fractional shares, to the
next largest number of whole shares) due such holder of MuniVest New York
Insured Common Stock and MuniYield New York Insured III Common Stock. No
fractional shares of MuniYield New York Insured II Common Stock will be issued.
In lieu thereof, MuniVest New York Insured II's transfer agent, Boston
EquiServe, will aggregate all fractional shares of MuniYield New York Insured II
Common Stock and sell the resulting whole shares on the NYSE for the account of
all holders of fractional interests, and each such holder will be entitled to
the pro rata share of the proceeds from such sale upon surrender of the MuniVest
New York Insured Common Stock or MuniYield New York Insured III Common Stock
certificates. Similarly, each newly-opened account on the books of MuniYield New
York Insured II for the previous holders of MuniVest New York Insured AMPS would
represent the respective pro rata number of shares of MuniYield New York Insured
II Series B AMPS due such holder of MuniVest New York Insured AMPS, and each
newly-opened account on the books of MuniYield New York Insured II for the
previous holders of MuniYield New York Insured III AMPS would represent the
respective pro rata number of shares of MuniYield New York Insured II Series C
AMPS due such holder of MuniYield New York Insured III AMPS. See "Surrender and
Exchange of MuniVest New York Insured and MuniYield New York Insured III Stock
Certificates" below for a description of the procedures to be followed by
MuniVest New York Insured and MuniYield New York Insured III stockholders to
obtain their MuniYield New York Insured II Common Stock (and cash in lieu of
fractional shares, if any), MuniYield New York Insured II Series B AMPS or
MuniYield New York Insured II Series C AMPS, as the case may be.
 
     Accordingly, as a result of the Reorganization, every holder of MuniVest
New York Insured Common Stock and MuniYield New York Insured III Common Stock
would own shares of MuniYield New York Insured II Common Stock that (except for
cash payments received in lieu of fractional shares) would have an aggregate net
asset value immediately after the Exchange Date equal to the aggregate net asset
value of that stockholder's MuniVest New York Insured Common Stock or MuniYield
New York Insured III Common Stock immediately prior to the Exchange Date. Since
the MuniYield New York Insured II Common Stock would be issued at net asset
value in exchange for the net assets of MuniVest New York Insured and MuniYield
New York Insured III having a value equal to the aggregate net asset value of
those shares of MuniYield New York Insured II Common Stock, the net asset value
per share of MuniYield New York Insured II Common Stock should remain virtually
unchanged by the Reorganization. Similarly, since the MuniYield New York Insured
II Series B AMPS would be issued at a liquidation preference and value per share
equal to the liquidation preference and value per share of the MuniVest New York
Insured AMPS, and the MuniYield New York Insured II Series C AMPS would be
issued at a liquidation preference and value per share equal to the liquidation
preference and value per share of the MuniYield New York Insured III AMPS, the
respective liquidation preference and value per share of the MuniYield New York
Insured II Series B AMPS and the MuniYield New York Insured II Series C AMPS
will remain unchanged by the Reorganization. Thus, the Reorganization will
result in no dilution of net asset value of the MuniYield New York Insured II
Common Stock, other than to reflect the costs of the Reorganization, and will
result in no dilution of liquidation preference and value per share of the
MuniYield New York Insured II Series B AMPS
 
                                       57
   62
 
or MuniYield New York Insured II Series C AMPS. However, as a result of the
Reorganization, a stockholder of any of the Funds likely will hold a reduced
percentage of ownership in the larger combined entity than he or she did in
either of the constituent Funds.
 
PROCEDURE
 
     At meetings of the Boards of Directors of MuniVest New York Insured and
MuniYield New York Insured III held on May 3, 1996, and at a meeting of the
Board of Directors of MuniYield New York Insured II held on June 21, 1996, the
Board of Directors of each of the Funds, including all of the Directors who are
not "interested persons", as defined in the Investment Company Act, of MuniVest
New York Insured, MuniYield New York Insured II and MuniYield New York Insured
III unanimously approved the Agreement and Plan of Reorganization and the
submission of such Agreement and Plan of Reorganization to the Funds' respective
stockholders for approval.
 
     Also on June 21, 1996, the Board of Directors of MuniYield New York Insured
II approved the filing of separate Articles Supplementary to MuniYield New York
Insured II's Articles of Incorporation establishing the powers, rights and
preferences of the MuniYield New York Insured II Series B AMPS and the MuniYield
New York Insured II Series C AMPS in order that they may be given to holders of
MuniVest New York Insured AMPS and MuniYield New York Insured III AMPS as part
of the Reorganization.
 
     As a result of such Board approvals, MuniVest New York Insured, MuniYield
New York Insured II and MuniYield New York Insured III jointly filed a proxy
statement with the Commission soliciting a vote of the stockholders of MuniVest
New York Insured, MuniYield New York Insured II and MuniYield New York Insured
III to approve the Reorganization. The costs of such solicitation are to be paid
by MuniYield New York Insured II after the Reorganization so as to be borne
equally and exclusively on a per share basis by the holders of MuniVest New York
Insured Common Stock, MuniYield New York Insured II Common Stock and MuniYield
New York Insured III Common Stock. It is anticipated that annual meetings of
stockholders of MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III will be held on September 9, 1996. If the
stockholders of all three Funds approve the Reorganization, the Reorganization
will take place as soon as practicable after such approval, provided that the
Funds have obtained prior to that time a favorable private letter ruling from
the IRS concerning the tax consequences of the Reorganization as set forth in
the Agreement and Plan of Reorganization.
 
     THE BOARDS OF DIRECTORS OF MUNIVEST NEW YORK INSURED, MUNIYIELD NEW YORK
INSURED II AND MUNIYIELD NEW YORK INSURED III RECOMMEND THAT THE STOCKHOLDERS OF
THE RESPECTIVE FUNDS APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.
 
TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION
 
     The following is a summary of the significant terms of the Agreement and
Plan of Reorganization. This summary is qualified in its entirety by reference
to the Agreement and Plan of Reorganization, attached hereto as Exhibit I.
 
     Valuation of Assets and Liabilities.  The respective assets of MuniVest New
York Insured, MuniYield New York Insured II and MuniYield New York Insured III
will be valued on the business day prior to the Exchange Date (the "Valuation
Date"). The valuation procedures are the same for all three Funds: net asset
value per share of the MuniVest New York Insured Common Stock, the MuniYield New
York Insured II
 
                                       58
   63
 
Common Stock and the MuniYield New York Insured III Common Stock will be
determined as of 15 minutes after the close of business on the NYSE (generally,
4:00 P.M., New York time) on the Valuation Date. For the purpose of determining
the net asset value of a share of the MuniVest New York Insured Common Stock,
the MuniYield New York Insured II Common Stock or the MuniYield New York Insured
III Common Stock, the value of the securities held by the issuing Fund plus any
cash or other assets (including interest accrued but not yet received) minus all
liabilities (including accrued expenses) and the aggregate liquidation value of
the outstanding shares of AMPS of the issuing Fund is divided by the total
number of shares of Common Stock of the issuing Fund outstanding at such time.
Daily expenses, including the fees payable to FAM, will accrue on the Valuation
Date.
 
     The Municipal Bonds in which each Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value on the Valuation Date,
each Fund will utilize the valuations of portfolio securities furnished by a
pricing service approved by the Boards of Directors of the Funds. The pricing
service typically values portfolio securities at the bid price or the yield
equivalent when quotations are readily available. Municipal Bonds for which
quotations are not readily available will be valued at fair market value on a
consistent basis as determined by the pricing service using a matrix system to
determine valuations. The Boards of Directors of MuniVest New York Insured,
MuniYield New York Insured II and MuniYield New York Insured III have determined
in good faith that the use of a pricing service is a fair method of determining
the valuation of portfolio securities. Positions in financial futures contracts
will be valued on the Valuation Date at closing prices for such contracts
established by the exchange on which they are traded, or if market quotations
are not readily available, will be valued at fair value on a consistent basis
using methods determined in good faith by the Board of Directors.
 
     Distribution of MuniYield New York Insured II Common Stock, MuniYield New
York Insured II Series B AMPS and MuniYield New York Insured II Series C
AMPS.  On the Exchange Date, MuniYield New York Insured II will issue to
MuniVest New York Insured and MuniYield New York Insured III a number of shares
of MuniYield New York Insured II Common Stock the aggregate net asset value of
which will equal the respective aggregate net asset value of shares of MuniVest
New York Insured Common Stock or MuniYield New York Insured III Common Stock, as
applicable, on the Valuation Date. Each holder of MuniVest New York Insured
Common Stock and MuniYield New York Insured III Common Stock will receive the
number of shares of MuniYield New York Insured II Common Stock corresponding to
his or her proportionate interest in the respective aggregate net asset value of
the MuniVest New York Insured Common Stock or the MuniYield New York Insured III
Common Stock, as applicable.
 
     On the Exchange Date, MuniYield New York Insured II also will issue (i) to
MuniVest New York Insured a number of shares of MuniYield New York Insured II
Series B AMPS the aggregate liquidation preference and value of which will equal
the aggregate liquidation preference and value of MuniVest New York Insured AMPS
on the Valuation Date, and (ii) to MuniYield New York Insured III a number of
shares of MuniYield New York Insured II Series C AMPS the aggregate liquidation
preference and value of which will equal the aggregate liquidation preference
and value of MuniYield New York Insured III AMPS on the Valuation Date. Each
holder of MuniVest New York Insured AMPS or MuniYield New York Insured III AMPS,
as the case may be, will receive the number of shares of MuniYield New York
Insured II Series B AMPS or MuniYield New York Insured II Series C AMPS
corresponding to his or her proportionate interest in the aggregate liquidation
preference and value of the MuniVest New York Insured AMPS or the MuniYield New
York Insured III AMPS. No sales charge or fee of any kind will be charged to
MuniVest
 
                                       59
   64
 
New York Insured stockholders or MuniYield New York Insured III stockholders in
connection with their receipt of MuniYield New York Insured II Common Stock,
MuniYield New York Insured II Series B AMPS and MuniYield New York Insured II
Series C AMPS in the Reorganization. It is anticipated that the MuniYield New
York Insured II Series B AMPS will follow a similar auction schedule and
procedures as those presently followed by the MuniVest New York Insured AMPS,
and that the MuniYield New York Insured II Series C AMPS will follow a similar
auction schedule and procedures as those presently followed by the MuniYield New
York Insured III AMPS. As a result of the Reorganization, the last dividend
period for the MuniVest New York Insured AMPS and MuniYield New York Insured III
AMPS prior to the Exchange Date may be shorter than the dividend period for such
AMPS determined as set forth in the applicable Articles Supplementary.
 
     Expenses.  MuniYield New York Insured II shall pay, subsequent to the
Exchange Date, all expenses incurred in connection with the Reorganization,
including, but not limited to, all costs related to the preparation and
distribution of materials distributed to each Fund's Board of Directors,
expenses incurred in connection with the preparation of the Agreement and Plan
of Reorganization, a registration statement on Form N-14 and a private letter
ruling request to the IRS, Commission and state securities commission filing
fees and legal and audit fees in connection with the Reorganization, costs of
printing and distributing this Proxy Statement and Prospectus, legal fees
incurred preparing each Fund's board materials, attending each Fund's board
meetings and preparing the minutes, accounting fees associated with each Fund's
financial statements, stock exchange fees, rating agency fees, portfolio
transfer taxes (if any), and any similar expenses incurred in connection with
the Reorganization. In this regard, expenses of the Reorganization will be
deducted from the assets of the combined fund so as to be borne equally and
exclusively on a per share basis by the holders of MuniVest New York Insured
Common Stock, MuniYield New York Insured II Common Stock and MuniYield New York
Insured III Common Stock. Neither MuniVest New York Insured, MuniYield New York
Insured II nor MuniYield New York Insured III shall pay any expenses of its
respective stockholders arising out of or in connection with the Reorganization.
 
     Required Approvals.  Under MuniVest New York Insured's Articles of
Incorporation (as amended to date and including Articles Supplementary
establishing the powers, rights and preferences of the MuniVest New York Insured
AMPS), relevant Maryland law and the rules of the NYSE, stockholder approval of
the Agreement and Plan of Reorganization requires the affirmative vote of
stockholders representing more than 50% of the outstanding shares of MuniVest
New York Insured Common Stock and MuniVest New York Insured AMPS, voting
together as a single class, and of the MuniVest New York Insured AMPS, voting
separately as a class. Similarly, under MuniYield New York Insured II's Articles
of Incorporation (as amended to date and including Articles Supplementary
establishing the powers, rights and preferences of the MuniYield New York
Insured II AMPS), relevant Maryland law and the rules of the NYSE, stockholder
approval of the Agreement and Plan of Reorganization requires the affirmative
vote of stockholders representing more than 50% of the outstanding shares of
MuniYield New York Insured II Common Stock and MuniYield New York Insured II
AMPS, voting together as a single class, and of the MuniYield New York Insured
II AMPS, voting separately as a class; and under MuniYield New York Insured
III's Articles of Incorporation (as amended to date and including Articles
Supplementary establishing the powers, rights and preferences of the MuniYield
New York Insured III AMPS), relevant Maryland law and the rules of the NYSE,
stockholder approval of the Agreement and Plan of Reorganization requires the
affirmative vote of stockholders representing more than 50% of the outstanding
shares of MuniYield New York Insured III
 
                                       60
   65
 
Common Stock and MuniYield New York Insured III AMPS, voting together as a
single class, and of the MuniYield New York Insured III AMPS, voting separately
as a class.
 
     Deregistration and Dissolution.  Following the transfer of the assets and
liabilities of MuniVest New York Insured and MuniYield New York Insured III to
MuniYield New York Insured II and the distribution of shares of MuniYield New
York Insured II Common Stock, MuniYield New York Insured II Series B AMPS and
MuniYield New York Insured II Series C AMPS to MuniVest New York Insured
stockholders and MuniYield New York Insured III stockholders, each of MuniVest
New York Insured and MuniYield New York Insured III will terminate its
registration under the Investment Company Act and its incorporation under
Maryland law and will withdraw its authority to do business in any state where
it is required to do so.
 
     Amendments and Conditions.  The Agreement and Plan of Reorganization may be
amended at any time prior to the Exchange Date with respect to any of the terms
therein. The obligations of MuniVest New York Insured, MuniYield New York
Insured II and MuniYield New York Insured III pursuant to the Agreement and Plan
of Reorganization are subject to various conditions, including a registration
statement on Form N-14 being declared effective by the Commission, approval of
the stockholders of MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III, a favorable IRS ruling being received as to tax
matters, an opinion of counsel as to securities matters being received and the
continuing accuracy of various representations and warranties of MuniVest New
York Insured, MuniYield New York Insured II and MuniYield New York Insured III
being confirmed by the respective parties.
 
     Postponement, Termination.  Under the Agreement and Plan of Reorganization,
the Board of Directors of any of the Funds may cause the Reorganization to be
postponed or abandoned should such Board determine that it is in the best
interests of the stockholders of its respective Fund to do so. The Agreement and
Plan of Reorganization may be terminated, and the Reorganization abandoned at
any time (whether before or after adoption thereof by the stockholders of any of
the Funds) prior to the Exchange Date, or the Exchange Date may be postponed:
(i) by mutual consent of the Boards of Directors of the three Funds; (ii) by the
Board of Directors of MuniVest New York Insured if any condition to MuniVest New
York Insured's obligations set forth in Section 9 of the Agreement and Plan of
Reorganization has not been fulfilled or waived by such Board; (iii) by the
Board of Directors of MuniYield New York Insured II if any condition to
MuniYield New York Insured II's obligations set forth in Section 10 of the
Agreement and Plan of Reorganization has not been fulfilled or waived by such
Board; or (iv) by the Board of Directors of MuniYield New York Insured III if
any condition to MuniYield New York Insured III's obligations set forth in
Section 11 of the Agreement and Plan of Reorganization has not been fulfilled or
waived by such Board.
 
POTENTIAL BENEFITS TO COMMON STOCKHOLDERS OF MUNIVEST NEW YORK INSURED,
MUNIYIELD NEW YORK INSURED II AND MUNIYIELD NEW YORK INSURED III AS A RESULT OF
THE REORGANIZATION
 
     In approving the Reorganization, the Board of Directors of each Fund
identified certain benefits that are likely to result from the Reorganization,
including lower expenses per share of Common Stock, greater efficiency and
flexibility in portfolio management and a more liquid trading market for the
shares of Common Stock of the combined fund. With respect to each of MuniVest
New York Insured and MuniYield New York Insured III, following the
Reorganization their respective stockholders will remain invested in a
closed-end fund that has investment objectives and policies similar to that of
MuniVest New York Insured and MuniYield New York Insured III. The Boards also
considered the possible risks and costs of combining the Funds, and examined the
relative credit strength, maturity characteristics, mix of type and purpose, and
yield
 
                                       61
   66
 
of the Funds' portfolios of Municipal Bonds and the costs involved in a
transaction such as the Reorganization. The Boards noted the many similarities
between the Funds, including their virtually identical investment objectives and
investment policies, their common management and their similar portfolios of
Municipal Bonds. Based on these factors, the Boards concluded that the
Reorganization (i) presents no significant risks that would outweigh the
benefits discussed above and (ii) involves minimal costs (including relatively
minor legal, accounting and administrative costs).
 
     The surviving fund that would result from the Reorganization would have a
larger asset base than any of the Funds has currently. Based on data presented
by FAM, the Board of each Fund believes that administrative expenses for a
larger combined fund would be less than the aggregate expenses for the
individual Funds, resulting in a lower expense ratio for common stockholders of
the combined fund and higher earnings per common share. In particular, certain
fixed costs, such as costs of printing stockholder reports and proxy statements,
legal expenses, audit fees, mailing costs and other expenses will be spread
across a larger asset base, thereby lowering the expense ratio for the combined
fund. To illustrate the potential economies of scale, as of April 30, 1996, the
total annualized operating expense ratio for MuniVest New York Insured was
0.76%, based on average net assets of approximately $145.0 million including
AMPS, and 1.15%, based on average net assets of approximately $96.0 million
excluding AMPS, the total annualized operating expense ratio for MuniYield New
York Insured II was 0.72%, based on average net assets of approximately $234.6
million including AMPS, and 1.02%, based on average net assets of approximately
$164.6 million excluding AMPS, and the total annualized operating expense ratio
for MuniYield New York Insured III was 0.90%, based on average net assets of
approximately $78.3 million including AMPS, and 1.32%, based on average net
assets of approximately $53.3 million excluding AMPS. If the Reorganization had
taken place on April 30, 1996, the overall operating expense ratio for the
combined fund on a pro forma basis would have been 0.66%, based on average net
assets of approximately $457.9 million including AMPS, and 0.97%, based on
average net assets of approximately $313.9 million excluding AMPS.
 
     Management projections estimate that MuniYield New York Insured II will
have net assets in excess of $441.8 million upon completion of the
Reorganization. A larger asset base should provide benefits in portfolio
management. After the Reorganization, MuniYield New York Insured II should be
able to purchase large amounts of Municipal Bonds at more favorable prices than
any of the Funds separately and, with this greater purchasing power, request
improvements in the terms of the Municipal Bonds (e.g., added indenture
provisions covering call protection, sinking funds and audits for the benefit of
large holders) prior to purchase.
 
     Based on the foregoing, the Boards concluded that the Reorganization
presents no significant risks or costs (including legal, accounting and
administrative costs) that would outweigh the benefits discussed above.
 
     In approving the Reorganization, the Board of Directors of each Fund
determined that, with respect to net asset value and liquidation preference, the
interests of existing stockholders of the Fund would not be diluted as a result
of the Reorganization. Although the Reorganization is expected to result in a
reduction in net asset value per share of the combined fund after the
Reorganization of approximately $.01 as a result of the estimated costs of the
Reorganization, management of each Fund advised its Board that it expects that
such costs would be recovered within [18] months after the Exchange Date.
 
     It is not anticipated that the Reorganization directly would benefit the
holders of shares of MuniVest New York Insured AMPS, MuniYield New York Insured
II AMPS or MuniYield New York Insured III AMPS; however, the Reorganization will
not adversely affect the holders of shares of AMPS of any of the
 
                                       62
   67
 
Funds and the expenses of the Reorganization will not be borne by the holders of
shares of AMPS of any of the Funds.
 
SURRENDER AND EXCHANGE OF MUNIVEST NEW YORK INSURED AND MUNIYIELD NEW YORK
INSURED III STOCK CERTIFICATES
 
     After the Exchange Date, each holder of an outstanding certificate or
certificates formerly representing shares of MuniVest New York Insured Common
Stock, MuniVest New York Insured AMPS, MuniYield New York Insured III Common
Stock or MuniYield New York Insured III AMPS, as the case may be, will be
entitled to receive, upon surrender of his or her certificate or certificates, a
certificate or certificates representing the number of shares of MuniYield New
York Insured II Common Stock, MuniYield New York Insured II Series B AMPS or
MuniYield New York Insured II Series C AMPS distributable with respect to such
holder's shares of MuniVest New York Insured Common Stock, MuniVest New York
Insured AMPS, MuniYield New York Insured III Common Stock or MuniYield New York
Insured III AMPS, together with cash in lieu of any fractional shares. Promptly
after the Exchange Date, the transfer agent for the MuniYield New York Insured
II Common Stock, the MuniYield New York Insured II Series B AMPS or the
MuniYield New York Insured II Series C AMPS, as the case may be, will mail to
each holder of certificates formerly representing shares of MuniVest New York
Insured Common Stock, MuniVest New York Insured AMPS, MuniYield New York Insured
III Common Stock or MuniYield New York Insured III AMPS, as the case may be, a
letter of transmittal for use in surrendering his or her certificates for
certificates representing shares of MuniYield New York Insured II Common Stock,
MuniYield New York Insured II Series B AMPS or MuniYield New York Insured II
Series C AMPS, as the case may be, and cash in lieu of any fractional shares.
 
     PLEASE DO NOT SEND IN ANY STOCK CERTIFICATES AT THIS TIME. UPON
CONSUMMATION OF THE REORGANIZATION, MUNIVEST NEW YORK INSURED AND MUNIYIELD NEW
YORK INSURED III COMMON AND PREFERRED STOCKHOLDERS WILL BE FURNISHED WITH
INSTRUCTIONS FOR EXCHANGING THEIR MUNIVEST NEW YORK INSURED OR MUNIYIELD NEW
YORK INSURED III STOCK CERTIFICATES FOR MUNIYIELD NEW YORK INSURED II STOCK
CERTIFICATES AND, IF APPLICABLE, CASH IN LIEU OF FRACTIONAL SHARES.
 
     From and after the Exchange Date, certificates formerly representing shares
of MuniVest New York Insured Common Stock, MuniVest New York Insured AMPS,
MuniYield New York Insured III Common Stock or MuniYield New York Insured III
AMPS, as the case may be, will be deemed for all purposes to evidence ownership
of the number of full shares of MuniYield New York Insured II Common Stock,
MuniYield New York Insured II Series B AMPS or MuniYield New York Insured II
Series C AMPS distributable with respect to such shares of MuniVest New York
Insured and MuniYield New York Insured III in the Reorganization, provided, that
until such MuniVest New York Insured or MuniYield New York Insured III stock
certificates have been so surrendered, no dividends payable to the holders of
record of MuniYield New York Insured II Common Stock, MuniYield New York Insured
II Series B AMPS or MuniYield New York Insured II Series C AMPS, as the case may
be, as of any date subsequent to the Exchange Date will be paid to the holders
of such outstanding MuniVest New York Insured or MuniYield New York Insured III
stock certificates. Dividends payable to holders of record of shares of
MuniYield New York Insured II Common Stock, MuniYield New York Insured II Series
B AMPS or MuniYield New York Insured II Series C AMPS, as the case may be, as of
any date after the Exchange Date and prior to the exchange of certificates by
any MuniVest New York Insured or MuniYield New York Insured III stockholder
 
                                       63
   68
 
will be paid to such stockholder, without interest, at the time such stockholder
surrenders his or her MuniVest New York Insured or MuniYield New York Insured
III stock certificates for exchange.
 
     From and after the Exchange Date, there will be no transfers on the stock
transfer books of MuniVest New York Insured and MuniYield New York Insured III.
If, after the Exchange Date, certificates representing shares of MuniVest New
York Insured Common Stock, MuniVest New York Insured AMPS, MuniYield New York
Insured III Common Stock or MuniYield New York Insured III AMPS are presented to
MuniYield New York Insured II, they will be cancelled and exchanged for
certificates representing MuniYield New York Insured II Common Stock, MuniYield
New York Insured II Series B AMPS or MuniYield New York Insured II Series C
AMPS, as the case may be, and cash in lieu of fractional shares, if any,
distributable with respect to such MuniVest New York Insured Common Stock,
MuniVest New York Insured AMPS, MuniYield New York Insured III Common Stock or
MuniYield New York Insured III AMPS in the Reorganization.
 
TAX CONSEQUENCES OF THE REORGANIZATION
 
     General.  The Reorganization has been structured with the intention that it
qualify for Federal income tax purposes as a tax-free reorganization under
Section 368(a)(1)(C) of the Code. Each of the three Funds has elected and
qualified for the special tax treatment afforded RICs under the Code, and
MuniYield New York Insured II intends to continue to so qualify after the
Reorganization. MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III have jointly requested a private letter ruling
from the IRS that for Federal income tax purposes: (i) the Reorganization, as
described, will constitute a reorganization within the meaning of Section
368(a)(1)(C) of the Code, and each of MuniVest New York Insured, MuniYield New
York Insured II and MuniYield New York Insured III will be deemed a "party" to a
Reorganization within the meaning of Section 361(b) of the Code; (ii) in
accordance with Section 368(a) of the Code, no gain or loss will be recognized
to MuniVest New York Insured or MuniYield New York Insured III as a result of
the Reorganization or on the distribution of MuniYield New York Insured II
Common Stock, MuniYield New York Insured II Series B AMPS and MuniYield New York
Insured II Series C AMPS to MuniVest New York Insured stockholders and MuniYield
New York Insured III stockholders under Section 361(c)(1) of the Code; (iii)
under Section 1032 of the Code, no gain or loss will be recognized to MuniYield
New York Insured II as a result of the Reorganization; (iv) in accordance with
Section 354(a)(1) of the Code, no gain or loss will be recognized to the
stockholders of MuniVest New York Insured or MuniYield New York Insured III on
the receipt of MuniYield New York Insured II Common Stock, MuniYield New York
Insured II Series B AMPS and MuniYield New York Insured II Series C AMPS in
exchange for their corresponding MuniVest New York Insured Common Stock,
MuniVest New York Insured AMPS, MuniYield New York Insured III Common Stock or
MuniYield New York Insured III AMPS (except to the extent that MuniVest New York
Insured common stockholders and MuniYield New York Insured III common
stockholders receive cash representing an interest in fractional shares of
MuniYield New York Insured II in the Reorganization); (v) in accordance with
Section 362(b) of the Code, the tax basis of the MuniVest New York Insured
assets and the MuniYield New York Insured III assets in the hands of MuniYield
New York Insured II will be the same as the tax basis of such assets in the
hands of MuniVest New York Insured and MuniYield New York Insured III
immediately prior to the consummation of the Reorganization; (vi) in accordance
with Section 358 of the Code, immediately after the Reorganization, the tax
basis of the MuniYield New York Insured II Common Stock, MuniYield New York
Insured II Series B AMPS and MuniYield New York Insured II Series C AMPS
received by the
 
                                       64
   69
 
stockholders of MuniVest New York Insured and MuniYield New York Insured III in
the Reorganization will be equal, in the aggregate, to the tax basis of the
MuniVest New York Insured Common Stock, MuniVest New York Insured AMPS,
MuniYield New York Insured III Common Stock and MuniYield New York Insured III
AMPS surrendered in exchange; (vii) in accordance with Section 1223 of the Code,
a stockholder's holding period for the MuniYield New York Insured II Common
Stock, MuniYield New York Insured II Series B AMPS and MuniYield New York
Insured II Series C AMPS will be determined by including the period for which
such stockholder held the MuniVest New York Insured Common Stock, MuniVest New
York Insured AMPS, MuniYield New York Insured III Common Stock or MuniYield New
York Insured III AMPS exchanged therefor, provided, that such MuniVest New York
Insured or MuniYield New York Insured III shares were held as a capital asset;
(viii) in accordance with Section 1223 of the Code, MuniYield New York Insured
II's holding period with respect to the MuniVest New York Insured assets and the
MuniYield New York Insured III assets transferred will include the period for
which such assets were held by MuniVest New York Insured and MuniYield New York
Insured III; (ix) the payment of cash to MuniVest New York Insured stockholders
and MuniYield New York Insured III stockholders in lieu of fractional shares of
MuniYield New York Insured II will be treated as though the fractional shares
were distributed as part of the Reorganization and then redeemed, with the
result that such MuniVest New York Insured and MuniYield New York Insured III
stockholders will have short- or long-term capital gain or loss to the extent
that the cash distribution differs from the basis allocable to the MuniYield New
York Insured II fractional shares; and (x) the taxable year of each of MuniVest
New York Insured and MuniYield New York Insured III will end on the effective
date of the Reorganization and pursuant to Section 381(a) of the Code and
regulations thereunder, MuniYield New York Insured II will succeed to and take
into account certain tax attributes of MuniVest New York Insured and MuniYield
New York Insured III, such as earnings and profits, capital loss carryovers and
method of accounting.
 
     As noted in the discussion under "Comparison of the Funds--Tax Rules
Applicable to MuniVest New York Insured, MuniYield New York Insured II,
MuniYield New York Insured III and Their Stockholders", a Fund must distribute
annually at least 90% of its net taxable and tax-exempt income. A distribution
only will be counted for this purpose if it qualifies for the dividends paid
deduction under the Code. In the opinion of Brown & Wood, the issuance of
MuniYield New York Insured II Series B AMPS and MuniYield New York Insured II
Series C AMPS pursuant to the Reorganization in addition to the already existing
MuniYield New York Insured II Series A AMPS will not cause distributions on any
series of AMPS to be treated as preferential dividends ineligible for the
dividends paid deduction. It is possible that the IRS may assert that, because
there are several series of AMPS, distributions on such shares are preferential
under the Code and therefore not eligible for the dividends paid deduction. If
the IRS successfully disallowed the dividends paid deduction for dividends on
the AMPS, MuniYield New York Insured II could lose the special tax treatment
afforded RICs. In this case, dividends on the shares of AMPS would not be exempt
from Federal income tax. Additionally, MuniYield New York Insured II would be
subject to the alternative minimum tax.
 
     Stockholders should consult their tax advisers regarding the effect of the
Reorganization in light of their individual circumstances. As the foregoing
relates only to Federal income tax consequences, stockholders also should
consult their tax advisers as to the foreign, state and local tax consequences
of the Reorganization.
 
     Status as a Regulated Investment Company.  MuniVest New York Insured,
MuniYield New York Insured II and MuniYield New York Insured III have elected
and qualified for taxation as RICs under
 
                                       65

Sections 851-855 of the Code, and after the Reorganization MuniYield New York
Insured II intends to continue to so qualify.

- ---------------
(1) Each of the nominees is a director, trustee or member of an advisory board
    of certain other investment companies for which FAM or MLAM acts as
    investment adviser. See "Compensation of Directors" below.
(2) Member of the Audit Committee of the Board of Directors.
(3) Interested person, as defined in the Investment Company Act, of the Fund.
 
COMMITTEE AND BOARD MEETINGS
 
     The Board of Directors of each Fund has a standing Audit Committee, which
consists of the Directors who are not "interested persons", as defined in the
Investment Company Act, of the Fund. The principal purpose of the Audit
Committee is to review the scope of the annual audit conducted by each Fund's
independent auditors and the evaluation by such auditors of the accounting
procedures followed by the Fund. The non-interested Directors have retained
independent legal counsel to assist them in connection with these duties. None
of the Boards of Directors has a nominating committee. During the fiscal year
ended October 31, 1995, the Boards of Directors and the Audit Committees of
MuniVest New York Insured, MuniYield New York Insured II and MuniYield New York
Insured III each held four quarterly meetings. All of the Directors of each Fund
then in office attended at least 75% of the total number of meetings of the
Board of Directors and the total number of meetings held by all of the
committees of the Board on which they served during such period.
 
COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Securities Exchange Act"), requires each Fund's officers, Directors and persons
who own more than ten percent of a registered class of the Fund's equity
securities, to file reports of ownership and changes in ownership on Forms 3, 4
and 5 with the Commission and the NYSE. Officers, Directors and greater than ten
percent stockholders are required by Commission regulations to furnish the Fund
with copies of all Forms 3, 4 and 5 that they file.
 
     Based solely on each Fund's review of the copies of such forms, and
amendments thereto, furnished to it during or with respect to its most recent
fiscal year, and written representations from certain reporting persons that
they were not required to file Forms 5 with respect to the most recent fiscal
year, each Fund believes that all of its officers, Directors, greater than ten
percent beneficial owners and other persons subject to Section 16
 
                                       72
   77
 
of the Securities Exchange Act because of the requirements of Section 30 of the
Investment Company Act (i.e., any advisory board member, investment adviser or
affiliated person of the Fund's investment adviser), have complied with all
filing requirements applicable to them with respect to transactions during the
Fund's most recent fiscal year.
 
INTERESTED PERSONS
 
     Each Fund considers Mr. Zeikel to be an "interested person" of the Fund
within the meaning of Section 2(a)(19) of the Investment Company Act as a result
of the positions he holds with FAM and its affiliates. Mr. Zeikel is the
President of each Fund, the President of FAM and the President of MLAM.
 
COMPENSATION OF DIRECTORS
 
     FAM, the investment adviser for MuniVest New York Insured, MuniYield New
York Insured II and MuniYield New York Insured III, pays all compensation of all
officers of each Fund and all Directors of each Fund who are affiliated with ML
& Co. or its subsidiaries. MuniVest New York Insured pays each Director who is
not affiliated with FAM a fee of $2,500 per year plus $250 per regular meeting
attended, together with such Director's actual out-of-pocket expenses relating
to attendance at meetings. The Fund also pays each member of its Audit
Committee, which consists of all of the non-affiliated Directors, a fee of $500
per year plus $125 per meeting attended, together with such Director's
out-of-pocket expenses relating to attendance at meetings. These fees and
expenses for the fiscal year ended October 31, 1995 aggregated $22,627 for
MuniVest New York Insured.
 
     MuniYield New York Insured II pays each Director who is not affiliated with
FAM a fee of $2,500 per year plus $250 per regular meeting attended, together
with such Director's actual out-of-pocket expenses relating to attendance at
meetings. The Fund also pays each member of its Audit Committee, which consists
of all of the non-affiliated Directors, a fee of $500 per year plus $125 per
meeting attended, together with such Director's out-of-pocket expenses relating
to attendance at meetings. These fees and expenses for the fiscal year ended
October 31, 1995 aggregated $23,759 for MuniYield New York Insured II.
 
     MuniYield New York Insured III pays each Director who is not affiliated
with FAM a fee of $2,500 per year plus $250 per regular meeting attended,
together with such Director's actual out-of-pocket expenses relating to
attendance at meetings. The Fund also pays each member of its Audit Committee,
which consists of all of the non-affiliated Directors, a fee of $500 per year
plus $125 per meeting attended, together with such Director's out-of-pocket
expenses relating to attendance at meetings. These fees and expenses for the
fiscal year ended October 31, 1995 aggregated $21,468 for MuniYield New York

                       SELECTION OF INDEPENDENT AUDITORS
 
     The Board of Directors of MuniVest New York Insured, including a majority
of the Directors who are not "interested persons", as defined in the Investment
Company Act, of the Fund, has selected the firm of Ernst & Young LLP as
independent auditors, to audit the financial statements of the Fund for the
current fiscal year ending October 31, 1996.
 
     The Board of Directors of MuniYield New York Insured II, including a
majority of the Directors who are not "interested persons" of the Fund, has
selected the firm of Deloitte & Touche LLP as independent auditors, to audit the
financial statements of the Fund for the current fiscal year ending October 31,
1996. However, in the event that the Reorganization is approved by the requisite
number of stockholders of each Fund and the Reorganization takes place prior to
October 31, 1996, the Board of Directors of MuniYield New York Insured II,
including a majority of the Directors who are not "interested persons" of the
Fund, have selected the firm of Ernst & Young LLP as independent auditors, to
audit the financial statements of the combined fund for the fiscal year ending
October 31, 1996.
 
                                       75
   80
 
     The Board of Directors of MuniYield New York Insured III, including a
majority of the Directors who are not "interested persons" of the Fund, has
selected the firm of Ernst & Young LLP as independent auditors, to audit the
financial statements of the Fund for the current fiscal year ending October 31,
1996.
 
     The Funds know of no direct or indirect financial interest of such firms in
the Funds. Such appointment is subject to ratification or rejection by the
stockholders of the Funds. If the stockholders of MuniVest New York Insured,
MuniYield New York Insured II and MuniYield New York Insured III approve the
Reorganization, then the independent auditors selected at the Meetings for
MuniYield New York Insured II will serve as the independent auditors of the
combined fund until its next Annual Meeting of Stockholders. If the stockholders
of either MuniVest New York Insured, MuniYield New York Insured II or MuniYield
New York Insured III vote against the Reorganization, then the independent
auditors of each Fund selected at the Meetings will continue to serve until the
next Annual Meeting of Stockholders of each Fund. Unless a contrary
specification is made, the accompanying proxy will be voted in favor of
ratification of the selection of such auditors.
 
     Deloitte & Touche LLP also acts as independent auditors for ML & Co. and
all of its subsidiaries and for most other investment companies for which FAM or
MLAM acts as investment adviser. The fees received by Deloitte & Touche LLP from
these other entities are substantially greater, in the aggregate, than the total
fees received by it from MuniYield New York Insured II. The Board of Directors
of MuniYield New York Insured II considered the fact that Deloitte & Touche LLP
has been retained as the independent auditors of ML & Co. and the other entities
described above in its evaluation of the independence of Deloitte & Touche LLP
with respect to MuniYield New York Insured II.
 
     Ernst & Young LLP also acts as independent auditors for several other
investment companies for which FAM or MLAM acts as investment adviser. The fees
received by Ernst & Young LLP from these other entities are substantially
greater, in the aggregate, than the total fees received by it from MuniVest New
York Insured and MuniYield New York Insured III. The Board of Directors of each
of MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III considered the fact that Ernst & Young LLP has been retained as
the independent auditors of the other entities described above in its evaluation
of the independence of Ernst & Young LLP with respect to MuniVest New York
Insured, MuniYield New York Insured II or MuniYield New York Insured III, as
applicable.
 
     Representatives of Deloitte & Touche LLP or Ernst & Young LLP, as
applicable, are expected to be present at the Meetings and will have the
opportunity to make a statement if they so desire and to respond to questions
from stockholders.
 
                   INFORMATION CONCERNING THE ANNUAL MEETINGS
 
DATE, TIME AND PLACE OF MEETINGS
 
     The Meetings will be held on September 9, 1996 at the offices of MLAM, 800
Scudders Mill Road, Plainsboro, New Jersey at 11:45 A.M., New York time (for
MuniVest New York Insured), 12:00 noon, New York time (for MuniYield New York
Insured II) and 12:15 P.M., New York time (for MuniYield New York Insured III).

SOLICITATION, REVOCATION AND USE OF PROXIES
 
     A stockholder executing and returning a proxy has the power to revoke it at
any time prior to its exercise by executing a superseding proxy or by submitting
a notice of revocation to the Secretary of MuniVest New York Insured, MuniYield
New York Insured II or MuniYield New York Insured III, as the case may be.
Although mere attendance at the Meetings will not revoke a proxy, a stockholder
present at the Meetings may withdraw his proxy and vote in person.
 
     All shares represented by properly executed proxies, unless such proxies
previously have been revoked, will be voted at the Meetings in accordance with
the directions on the proxies; if no direction is indicated, the shares will be
voted "FOR" (i) the approval of the Agreement and Plan of Reorganization, (ii)
the election of Directors and (iii) the ratification of the selection of
Deloitte & Touche LLP or Ernst & Young LLP, as applicable, as independent
accountants.
 
     It is not anticipated that any matters other than (i) the adoption of the
Agreement and Plan of Reorganization, (ii) the election of Directors and (iii)
the ratification of the selection of Deloitte & Touche LLP or Ernst & Young LLP,
as applicable, will be brought before the Meetings. If, however, any other
business properly is brought before the Meetings, proxies will be voted in
accordance with the judgment of the persons designated on such proxies.

VOTING RIGHTS AND REQUIRED VOTE
 
     For purposes of this Proxy Statement and Prospectus, each share of MuniVest
New York Insured Common Stock, MuniVest New York Insured AMPS, MuniYield New
York Insured II Common Stock, MuniYield New York Insured II AMPS, MuniYield New
York Insured III Common Stock and MuniYield New York Insured III AMPS is
entitled to one vote. Approval of the Agreement and Plan of Reorganization
requires the affirmative vote of stockholders representing (i) a majority of the
outstanding shares of MuniVest New York Insured Common Stock and MuniVest New
York Insured AMPS, voting together as a single class, and of the MuniVest New
York Insured AMPS, voting separately as a class, (ii) a majority of the
outstanding shares of MuniYield New York Insured II Common Stock and MuniYield
New York Insured II AMPS, voting together as a single class, and of the
MuniYield New York Insured II AMPS, voting separately as a class, and (iii) a
majority of the outstanding shares of MuniYield New York Insured III Common
Stock and MuniYield New York Insured III AMPS, voting together as a single
class, and of the MuniYield New York Insured III AMPS, voting separately as a

     Under Maryland law, stockholders of a registered investment company whose
shares are traded publicly on a national securities exchange, such as MuniVest
New York Insured and MuniYield New York Insured III, are not entitled to demand
the fair value of their shares upon a transfer of assets; therefore, the
MuniVest New York Insured and MuniYield New York Insured III common stockholders
will be bound by the terms of the Reorganization, if approved at the Meetings.
However, any common stockholder of MuniVest New York Insured or MuniYield New
York Insured III may sell his or her shares of Common Stock at any time on the
NYSE. Conversely, since the MuniVest New York Insured AMPS and MuniYield New
York Insured III AMPS are not traded publicly on a national securities exchange,
shareholders of MuniVest New York Insured AMPS and MuniYield New York Insured
III AMPS will be entitled to appraisal rights upon the consummation of the
Reorganization. As stockholders of the corporation acquiring the assets of
MuniVest New York Insured and of MuniYield New York Insured III, neither holders
of MuniYield New York Insured II Common Stock nor holders of MuniYield New York
Insured II AMPS are entitled to appraisal rights under Maryland law.
 
     For purposes of each Meeting, a quorum consists of a majority of the shares
entitled to vote at the Meeting, present in person or by proxy. If, by the time
scheduled for each Meeting, a quorum of the applicable Fund's stockholders is
not present or if a quorum is present but sufficient votes in favor of the
Agreement and Plan of Reorganization are not received from the stockholders of
the applicable Fund, the persons named as proxies may propose one or more
adjournments of the Meeting to permit further solicitation of proxies from
 
                                       78
   83
 
stockholders. Any such adjournment will require the affirmative vote of a
majority of the shares of the applicable Fund present in person or by proxy and
entitled to vote at the session of the Meeting to be adjourned. The persons
named as proxies will vote in favor of any such adjournment if they determine
that adjournment and additional solicitation are reasonable and in the interests
of the applicable Fund's stockholders.
 
     With respect to the election of Directors, (i) holders of shares of
MuniVest New York Insured AMPS are entitled to elect two Directors of MuniVest
New York Insured and holders of shares of MuniVest New York Insured Common Stock
and MuniVest New York Insured AMPS, voting together as a single class, are
entitled to elect the remaining Directors of MuniVest New York Insured; (ii)
holders of shares of MuniYield New York Insured II AMPS are entitled to elect
two Directors of MuniYield New York Insured II and holders of shares of
MuniYield New York Insured II Common Stock and MuniYield New York Insured II
AMPS, voting together as a single class, are entitled to elect the remaining
Directors of MuniYield New York Insured II; and (iii) holders of shares of
MuniYield New York Insured III AMPS are entitled to elect two Directors of
MuniYield New York Insured III and holders of shares of MuniYield New York
Insured III Common Stock and MuniYield New York Insured III AMPS, voting
together as a single class, are entitled to elect the remaining Directors of
MuniYield New York Insured III. Assuming a quorum is present, (x) election of
the two Directors of MuniVest New York Insured, MuniYield New York Insured II or
MuniYield New York Insured III, as the case may be, to be elected by the holders
of shares of MuniVest New York Insured AMPS, MuniYield New York Insured II AMPS
or MuniYield New York Insured III AMPS, respectively, voting separately as a
class, will require the affirmative vote of a majority of the votes cast by the
holders of that Fund's AMPS, represented at the Meeting and entitled to vote;
and (y) election of the remaining Directors of MuniVest New York Insured,
MuniYield New York Insured II or MuniYield New York Insured III, as the case may
be, will require the affirmative vote of a majority of the votes cast by the
holders of their respective Common Stock and AMPS, represented at the Meetings
and entitled to vote, voting together as a single class.
 
     Approval of the ratification of the selection of Ernst & Young LLP as the
independent auditors of MuniVest New York Insured will require the affirmative
vote of a majority of the votes cast by the holders of MuniVest New York Insured
Common Stock and MuniVest New York Insured AMPS represented at the Meetings and
entitled to vote, voting together as a single class; approval of the
ratification of the selection of Deloitte & Touche LLP as the independent
auditors of MuniYield New York Insured II (or, in the event that the
Reorganization is approved by the requisite number of stockholders of each Fund
and the Reorganization takes place prior to October 31, 1996, approval of Ernst
& Young LLP as the independent auditors of the combined fund) will require the
affirmative vote of a majority of the votes cast by the holders of MuniYield New
York Insured II Common Stock and MuniYield New York Insured II AMPS represented
at the Meetings and entitled to vote, voting together as a single class; and
approval of the ratification of the selection of Ernst & Young LLP as the
independent auditors of MuniYield New York Insured III will require the
affirmative vote of a majority of the votes cast by holders of MuniYield New
York Insured III Common Stock and MuniYield New York Insured III AMPS
represented at the Meetings and entitled to vote, voting together as a single
class.

                             ADDITIONAL INFORMATION
 
     The expenses of preparation, printing and mailing of the enclosed form of
proxy, the accompanying Notice and this Proxy Statement and Prospectus will be
borne by MuniYield New York Insured II, the surviving fund after the
Reorganization, so as to be borne equally and exclusively on a per share basis
by the holders of MuniVest New York Insured Common Stock, MuniYield New York
Insured II Common Stock and MuniYield New York Insured III Common Stock.
 
     MuniVest New York Insured, MuniYield New York Insured II and MuniYield New
York Insured III likewise will reimburse banks, brokers and others for their
reasonable expenses in forwarding proxy solicitation materials to the beneficial
owners of shares of MuniVest New York Insured, MuniYield New York Insured II and
MuniYield New York Insured III and certain persons that MuniVest New York
Insured, MuniYield New York Insured II or MuniYield New York Insured III may
employ for their reasonable expenses in assisting in the solicitation of proxies
from such beneficial owners of shares of capital stock of MunIVest New York
Insured, MuniYield New York Insured II or MuniYield New York Insured III.
 
     In order to obtain the necessary quorum at the Meetings (i.e., a majority
of the shares of each class of each Fund's securities entitled to vote at the
Meetings, present in person or by proxy), supplementary solicitation may be made
by mail, telephone, telegraph or personal interview by officers of the Fund. The
Funds also may hire proxy solicitors at the expense of MuniYield New York
Insured II. It is anticipated that the cost of such supplementary solicitation,
if any, will be nominal.
 
     Broker-dealer firms, including Merrill Lynch, holding Fund shares in
"street name" for the benefit of their customers and clients will request the
instructions of such customers and clients on how to vote their shares on each
proposal before the Meetings. The Funds understand that, under the rules of the
NYSE, such broker-dealer firms may, without instructions from their customers
and clients, grant authority to the proxies designated to vote on the election
of a Board of Directors of each Fund to serve for the ensuing year (proposal 2)
and the ratification of the selection of Deloitte & Touche LLP or Ernst & Young
LLP, as applicable, as independent auditors for each Fund for the current fiscal
year (proposals 3 and 4) if no instructions have been received prior to the date
specified in the broker-dealer firm's request for voting instructions.
Broker-dealer firms, including Merrill Lynch, will not be permitted to grant
voting authority without instructions with respect to the approval of the
Agreement and Plan of Reorganization (proposal 1). The Funds will include shares
held of record by broker-dealers as to which such authority has been granted in
its tabulation of the total number of shares present for purposes of determining
whether the necessary quorum of shareholders of each Fund exists. Proxies which
are returned to a Fund but which are marked "abstain" or on which a
broker-dealer has declined to vote on any proposal ("broker non-votes") will be
counted as present for the purposes of determining a quorum. Merrill Lynch has
advised the Funds that it intends to exercise discretion over shares held in its
name for which no instructions have been received by voting such shares on
proposals 2, 3 and (in the case of MuniYield New York Insured II) 4 in the same
proportion as it has voted such shares for which it has received instructions.
However, abstentions and broker non-votes will not be counted as votes cast.
Abstentions and broker non-votes will not have an effect on the vote on
proposals 2, 3 and (in the case of MuniYield New York Insured II) 4; however,
abstentions and broker non-votes will have the same effect as a vote against
proposal 1.

REPORT OF INDEPENDENT AUDITORS
 
To the Shareholders and Board of Directors,
MuniVest New York Insured Fund, Inc.
 
We have audited the accompanying statement of assets, liabilities and capital of
MuniVest New York Insured Fund, Inc., including the schedule of investments, as
of October 31, 1995, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended and financial highlights for each of the periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1995 by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
MuniVest New York Insured Fund, Inc. at October 31, 1995, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and financial highlights for each of the
indicated periods, in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniVest New York Insured Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. The Fund determines
and makes available for publication the net asset value of its Common
Stock on a weekly basis. The Fund's Common Stock is listed on the
New York Stock Exchange under the symbol MVY. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent bid
price or yield equivalent as obtained by the Fund's pricing service
from dealers that make markets in such securities. Financial futures
contracts and options thereon, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges.
Options, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges or, lacking any sales, at the last
available bid price. Securities with remaining maturities of sixty
days or less are valued at amortized cost, which approximates market
value. Securities for which market quotations are not readily avail-
able are valued at fair value as determined in good faith by or under
the direction of the Board of Directors of the Fund, including valua-
tions furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing
service and its valuations are reviewed by the officers of the Fund
under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in
various portfolio strategies to seek to increase its return by hedging
its portfolio against adverse movements in the debt markets. Losses
may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at a
specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the contract.
Such receipts or payments are known as variation margin and are
recorded by the Fund as unrealized gains or losses. When the con-
tract is closed, the Fund records a realized gain or loss equal to the
difference between the value of the contract at the time it was
opened and the value at the time it was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the closing
transaction exceeds the premium paid or received).

Written and purchased options are non-income producing
investments.

(c) Income taxes--It is the Fund's policy to comply with the require-
ments of the Internal Revenue Code applicable to regulated invest-
ment companies and to distribute substantially all of its taxable
income to its shareholders. Therefore, no Federal income tax pro-
vision is required.

(d) Security transactions and investment income--Security trans-
actions are recorded on the dates the transactions are entered into
(the trade dates). Interest income is recognized on the accrual basis.
Discounts and market premiums are amortized into interest income.
Realized gains and losses on security transactions are determined
on the identified cost basis.

(e) Deferred organization and offering expenses--Deferred organiza-
tion expenses are amortized on a straight-line basis over a five-year
period. Direct expenses relating to the public offering of the Fund's
Common and Preferred Stock were charged to capital at the time of
issuance of the shares.
                                     F-10
   98
(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Fund Asset Management, L.P. ("FAM"). The general partner of FAM is

The aggregate cost of investments at October 31, 1995 for Federal
income tax purposes was $133,117,293.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of holders of Common Stock.

Common Stock
For the year ended October 31, 1995, shares issued and outstanding
remained constant at 7,204,432. At October 31, 1995, total paid-in
capital amounted to $100,957,824.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash dividends
at an annual rate that may vary for the successive dividend periods.
The yield in effect at October 31, 1995 was 3.70%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 1,960 AMPS authorized, issued and
outstanding with a liquidation preference of $25,000 per share, plus
accumulated and unpaid dividends of $24,836.

The Fund pays commissions to certain broker-dealers at the end
of each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $101,497 as
commissions.

5. Capital Loss Carryforward:

approximately $13,810,000, of which $6,831,000 expires in 2002
and $6,979,000 expires in 2003. This amount will be available to offset
like amounts of any future taxable gains.

ordinary income dividend to Common Stock shareholders in the
amount of $0.062339 per share, payable on November 29, 1995 to

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniVest New York Insured Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. These unaudited finan-
cial statements reflect all adjustments which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal recur-
ring nature. The Fund determines and makes available for publica-
tion the net asset value of its Common Stock on a weekly basis. The
Fund's Common Stock is listed on the New York Stock Exchange
under the symbol MVY. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent bid
price or yield equivalent as obtained by the Fund's pricing service
from dealers that make markets in such securities. Financial futures
contracts and options thereon, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges.
Options, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges or, lacking any sales, at the last
available bid price. Securities with remaining maturities of sixty
days or less are valued at amortized cost, which approximates market
value. Securities for which market quotations are not readily avail-
able are valued at fair value as determined in good faith by or under
the direction of the Board of Directors of the Fund, including valua-
tions furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing
service and its valuations are reviewed by the officers of the Fund
under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in
various portfolio strategies to seek to increase its return by hedging
its portfolio against adverse movements in the debt markets. Losses
may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at a
specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker an
amount of cash equal to the daily fluctuation in value of the contract.
Such receipts or payments are known as variation margin and are
recorded by the Fund as unrealized gains or losses. When the con-
tract is closed, the Fund records a realized gain or loss equal to the
difference between the value of the contract at the time it was
opened and the value at the time it was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the closing
transaction exceeds the premium paid or received).

Written and purchased options are non-income producing
investments.

(c) Income taxes--It is the Fund's policy to comply with the require-
ments of the Internal Revenue Code applicable to regulated invest-
ment companies and to distribute substantially all of its taxable
income to its shareholders. Therefore, no Federal income tax pro-
vision is required.

(d) Security transactions and investment income--Security trans-
actions are recorded on the dates the transactions are entered into
(the trade dates). Interest income is recognized on the accrual basis.
Discounts and market premiums are amortized into interest income.
Realized gains and losses on security transactions are determined
on the identified cost basis.
                                     F-18
   106
(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Fund Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned subsidiary
of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of 0.50% of
the Fund's average weekly net assets.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of FAM, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.

                                       ==========         ==========

tax purposes aggregated $3,615,276, of which $4,596,696 related to
appreciated securities and $981,420 related to depreciated securities.
The aggregate cost of investments at April 30, 1996 for Federal
income tax purposes was $144,656,130.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of holders of Common Stock.

Common Stock
For the six months ended April 30, 1996, shares issued and outstand-
ing remained constant at 7,204,432. At April 30, 1996, total paid-in
capital amounted to $100,957,824.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash dividends
at an annual rate that may vary for the successive dividend periods.
The yield in effect at April 30, 1996 was 3.85%.

As of April 30, 1996, there were 1,960 AMPS authorized, issued and
outstanding with a liquidation preference of $25,000 per share, plus
accumulated and unpaid dividends of $25,844.

The Fund pays commissions to certain broker-dealers at the end
of each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the six months ended
April 30, 1996, MLPF&S, an affiliate of FAM, earned $37,228 as
commissions.

5. Capital Loss Carryforward:
At October 31, 1995, the Fund had a net capital loss carryforward of
approximately $13,810,000, of which $6,831,000 expires in 2002, and
$6,979,000 expires in 2003. This amount will be available to offset
like amounts of any future taxable gains.

6. Subsequent Event:
On May 10, 1996, the Fund's Board of Directors declared an ordinary
income dividend to Common Stock shareholders in the amount of
$0.057601 per share, payable on May 30, 1996 to shareholders of
record as of May 21, 1996.

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield New York Insured Fund II, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. The Fund determines and
makes available for publication the net asset value of its Common
Stock on a weekly basis. The Fund's Common Stock is listed on the
New York Stock Exchange under the symbol MYT. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are valued
at their last sale price as of the close of such exchanges or,
lacking any sales, at the last available bid price. Securities with
remaining maturities of sixty days or less are valued at amortized
cost, which approximates market value. Securities for which market
quotations are not readily available are valued at their fair value
as determined in good faith by or under the direction of the Board
of Directors of the Fund, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing
securities or the intended purchase of securities. Futures contracts
are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial
margin as required by the exchange on which the transaction is
effected. Pursuant to the contract, the Fund agrees to receive from
or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are
known as variation margin and are recorded by the Fund as unrealized
gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of
the contract at the time it was opened and the value at the time it
was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund sells an option, an amount equal
to the premium received by the Fund is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

MuniYield New York Insured Fund II, Inc.                     October 31, 1995

(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or

securities. The aggregate cost of investments at October 31, 1995
for Federal income tax purposes was $222,844,382.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock
For the year ended October 31, 1995, shares issued and outstanding
remained constant at 11,114,832. At October 31, 1995, total paid-in
capital amounted to $155,903,821.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yield in effect at October 31, 1995 was 3.75%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 2,800 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share, plus accumulated and unpaid dividends of $14,384.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $66,149 as
commissions.

5. Capital Loss Carryforward:
At October 31, 1995, the Fund had a capital loss carryforward of
approximately $3,616,000, of which $1,841,000 expires in 2002 and

like amounts of any future taxable gains.

ordinary income dividend to Common Stock shareholders in the amount
of $0.069842 per share, payable on November 29, 1995 to shareholders

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield New York Insured Fund II, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. These unaudited financial
statements reflect all adjustments which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal
recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Stock on a weekly
basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MYT. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are valued
at their last sale price as of the close of such exchanges or,
lacking any sales, at the last available bid price. Securities with
remaining maturities of sixty days or less are valued at amortized
cost, which approximates market value. Securities for which market
quotations are not readily available are valued at their fair value
as determined in good faith by or under the direction of the Board
of Directors of the Fund, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract
or if the counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing
securities or the intended purchase of securities. Futures contracts
are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial
margin as required by the exchange on which the transaction is
effected. Pursuant to the contract, the Fund agrees to receive from
or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are
known as variation margin and are recorded by the Fund as unrealized
gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of
the contract at the time it was opened and the value at the time it
was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into

interest income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the

provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of 0.50% of
the Fund's average weekly net assets.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of FAM, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock

outstanding remained constant at 11,114,832. At April 30, 1996,
total paid-in capital amounted to $155,903,821.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yield in effect at April 30, 1996 was 3.85%.

As of April 30, 1996, there were 2,800 AMPS shares authorized,

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield New York Insured Fund III, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. The Fund determines and
makes available for publication the net asset value of its Common
Stock on a weekly basis. The Fund's Common Stock is listed on the
New York Stock Exchange under the symbol MYY. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are valued
at their last sale price as of the close of such exchanges or,
lacking any sales, at the last available bid price. Securities with
remaining maturities of sixty days or less are valued at amortized
cost, which approximates market value. Securities for which market
quotations are not readily available are valued at their fair value
as determined in good faith by or under the direction of the Board
of Directors of the Fund, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing
securities or the intended purchase of securities. Futures contracts
are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial
margin as required by the exchange on which the transaction is
effected. Pursuant to the contract, the Fund agrees to receive from
or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are
known as variation margin and are recorded by the Fund as unrealized
gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of
the contract at the time it was opened and the value at the time it
was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is
added to (or deducted from) the basis of the security acquired or
deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the
premiums received or paid (or gain or loss to the extent the cost of
the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the
accrual basis. Discounts and market premiums are amortized into
interest income. Realized gains and losses on security transactions
are determined on the identified cost basis.

(e) Deferred organization expenses and offering expenses--Deferred
organization expenses are amortized on a straight-line basis over a
five-year period.

Direct expenses relating to the public offering of
the Common and Preferred Stock were charged to capital at the time
of issuance.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock
For the year ended October 31, 1995, shares issued and outstanding
remained constant at 3,688,900. As of October 31, 1995, total paid-
in capital amounted to $51,510,298.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yield in effect at October 31, 1995 was
3.745%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 1,000 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share, plus accumulated and unpaid dividends of $51,300.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $50,359 as
commissions.

approximately $2,576,000, of which $971,000 expires in 2002 and

like amounts of any future taxable gains.

ordinary income dividend to Common Stock shareholders in the amount
of $0.066621 per share, payable on November 29, 1995 to shareholders

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield New York Insured Fund III, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. These unaudited financial
statements reflect all adjustments which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal
recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Stock on a weekly
basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MYY. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are valued
at their last sale price as of the close of such exchanges or,
lacking any sales, at the last available bid price. Securities with
remaining maturities of sixty days or less are valued at amortized
cost, which approximates market value. Securities for which market
quotations are not readily available are valued at their fair value
as determined in good faith by or under the direction of the Board
of Directors of the Fund, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing
securities or the intended purchase of securities. Futures contracts
are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial
margin as required by the exchange on which the transaction is
effected. Pursuant to the contract, the Fund agrees to receive from
or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are
known as variation margin and are recorded by the Fund as unrealized
gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of
the contract at the time it was opened and the value at the time it
was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is
added to (or deducted from) the basis of the security acquired or
deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the
premiums received or paid (or gain or loss to the extent the cost of
the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized

                                     F-54

into interest income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the

provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or

                                 ============   ============

As of April 30, 1996, net unrealized appreciation for Federal income
tax purposes aggregated $1,602,298, of which $2,216,622 related to
appreciated securities and $614,324 related to depreciated
securities. The aggregate cost of investments at April 30, 1996 for
Federal income tax purposes was $73,108,897.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock
For the six months ended April 30, 1996, shares issued and
outstanding remained constant at 3,688,900. As of April 30, 1996,
total paid-in capital amounted to $51,510,298.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yield in effect at April 30, 1996 was 3.77%.

As of April 30, 1996, there were 1,000 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the six months ended
April 30, 1996, MLPF&S, an affiliate of FAM, earned $25,068 as
commissions.

5. Capital Loss Carryforward:
At October 31, 1995, the Fund had a net capital loss carryforward of
approximately $2,576,000, of which $971,000 expires in 2002 and
$1,605,000 expires in 2003. This amount will be available to offset
like amounts of any future taxable gains.

income dividend to Common Stock shareholders in the amount of
$0.062407 per share, payable on May 30, 1996 to shareholders of

within the meaning of Section 361(b) of the Code; (ii) in accordance with
Section 361(a) of the Code, (a) no gain or loss will be recognized to MuniVest
New York Insured as a result of the Reorganization or on the distribution of
MuniYield New York Insured II Common Stock and, MuniYield New York Insured II
Series B AMPS to MuniVest New York Insured stockholders under Section 361(c)(1)
of the Code and no gain or loss will be recognized to MuniYield New York Insured

stockholders receive cash representing an interest in fractional shares of
MuniYield New York Insured II Common Stock in the Reorganization); (v) in
accordance with Section 362(b) of the Code, the tax basis of the MuniVest New
York Insured assets and the MuniYield New York Insured III assets in the hands
of MuniYield New York Insured II will be the same as the tax basis of such
assets in the hands of MuniVest New York Insured or MuniYield New York Insured
III immediately prior to the consummation of the Reorganization; (vi) in
accordance with Section 358 of the Code, immediately after the Reorganization,
the tax basis of the MuniYield New York Insured II Common Stock, MuniYield New
York Insured II Series B AMPS and MuniYield New York Insured II Series C AMPS
received by the stockholders of MuniVest New York Insured and MuniYield New York
Insured III in the Reorganization will be equal, in the aggregate, to the tax
basis of the MuniVest New York Insured Common Stock, MuniVest New York Insured
AMPS, MuniYield New York Insured III Common Stock and MuniYield New York Insured
III AMPS surrendered, respectively, in exchange; (vii) in accordance with

Section 1223 of the Code, a stockholder's holding period for the MuniYield New
York Insured II Common Stock, MuniYield New York Insured II Series B AMPS and

period for which such stockholder held the MuniVest New York Insured Common
Stock, MuniVest New York Insured AMPS, MuniYield New York Insured III Common
Stock or MuniYield New York Insured III AMPS exchanged therefor, as the case
maybe, provided, that such MuniVest New York Insured shares or MuniYield New

by MuniVest New York Insured or MuniYield New York Insured III; (ix) the payment
of cash to MuniVest New York Insured stockholders and MuniYield New York Insured
III stockholders in lieu of fractional shares of MuniYield New York Insured II
will be treated as though the fractional shares were distributed as part of the
Reorganization and then redeemed by MuniYield New York Insured II, with the
result that each MuniVest New York Insured stockholder and MuniYield New York
Insured III stockholder will have short- or long-term capital gain or loss to
the extent that the cash distribution differs from such stockholder's basis
allocable to the MuniYield New York Insured II fractional shares; and (x) the
taxable year of each of MuniVest New York Insured and MuniYield New York Insured
III will end on the effective date of the Reorganization and pursuant to Section
381(a) of the Code and regulations thereunder, MuniYield New York Insured II
will succeed to and take into account certain tax attributes of each of MuniVest
New York Insured and MuniYield New York Insured III, such as earnings and
profits, capital loss carryovers and method of accounting.

New York Insured III and their counsel in connection with the Reorganization and
all documents incidental thereto shall be satisfactory in form and substance to
MuniVest New York Insured.

the 1933 Act, and no stop order suspending such effectiveness shall have been
instituted or, to the knowledge of MuniYield New York Insured II or MuniYield

rules and regulations thereunder; (iii) on the basis of limited procedures
agreed upon by MuniVest New York Insured, MuniYield New York Insured II and

examination in accordance with generally accepted auditing standards) consisting
of a reading of any unaudited interim financial statements and unaudited
supplementary information of MuniYield New York Insured II included in the N-14
Registration Statement, and inquiries of certain officials of MuniYield New York
Insured II responsible for financial and accounting matters, nothing came to
their attention that caused them to believe that (a) such unaudited financial
statements and related unaudited supplementary information do not comply as to
form in all material respects with the applicable accounting requirements of
 
                                      I-22
   174

10.  MUNIYIELD NEW YORK INSURED II CONDITIONS.
 
     The obligations of MuniYield New York Insured II hereunder shall be subject
to the following conditions:
 
     (a) That this Agreement shall have been adopted, and the Reorganization
shall have been approved, by all of the requisite votes set forth in Section

Agreement, together with a schedule of investments with their respective dates
of acquisition and tax costs, all as of the Valuation Time, certified on each
fund's behalf by its respective President (or any Vice President) and its
Treasurer, and a certificate of both such officers, dated the Exchange Date,
certifying that as of the Valuation Time and as of the Exchange Date there has
been no material adverse change in the financial position of the fund since
October 31, 1995, other than changes in such fund's Investments since that date
or changes in the market value of such fund's Investments.
 
     (c) That each of MuniVest New York Insured and MuniYield New York Insured
III shall have furnished to MuniYield New York Insured II a certificate signed
by its respective President (or any Vice President) and its Treasurer, dated the
Exchange Date, certifying that as of the Valuation Time and as of the Exchange
Date all representations and warranties of MuniVest New York Insured or

York Insured II a letter from Ernst & Young LLP, dated the Exchange Date,
stating that such firm has performed a limited review of the Federal, state and
local income tax returns of MuniVest New York Insured for the period ended
October 31, 1995 (which returns originally were prepared and filed by MuniVest
New York Insured), and that based on such limited review, nothing came to their
attention which caused them to believe that such returns did not properly
reflect, in all material respects, the Federal, state and local income taxes of
MuniVest New York Insured for the period covered thereby; and that for the
period from November 1, 1995 to and including the Exchange Date and for any
taxable year of MuniVest New York Insured ending upon the

review to ascertain the amount of applicable Federal, state and local taxes, and
has determined that either such amount has been paid or reserves established for
payment of such taxes, this review to be based on unaudited financial data; and
that based on such limited review, nothing has come to their attention which
caused them to believe that the taxes paid or reserves set aside for payment of
such taxes were not adequate in all material respects for the satisfaction of
Federal, state and local taxes for the period from November 1, 1995 to and
including the Exchange Date and for the final taxable year of MuniVest New York
Insured ending upon liquidation or that MuniVest New York Insured had not
qualified as a regulated investment company for Federal income tax purposes for

Insured.
 
     (e) That MuniYield New York Insured III shall have delivered to MuniYield
New York Insured II a letter from Ernst & Young LLP, dated the Exchange Date,
stating that such firm has performed a limited review of the Federal, state and
local income tax returns of MuniYield New York Insured III for the period ended
October 31, 1995 (which returns originally were prepared and filed by MuniYield
New York Insured III), and that based on such limited review, nothing came to
their attention which caused them to believe that such returns did not properly
reflect, in all material respects, the Federal, state and local income taxes of
MuniYield New York Insured III for the period covered thereby; and that for the
period from November 1, 1995 to and including the Exchange Date and for any
taxable year of MuniYield New York Insured III ending upon the liquidation of
MuniYield New York Insured III, such firm has performed a limited review to
ascertain the amount of applicable Federal, state and local taxes, and has
determined that either such amount has been paid or reserves established for
payment of such taxes, this review to be based on unaudited financial data; and
that based on such limited review, nothing has come to their attention which
caused them to believe that the taxes paid or reserves set aside for payment of
such taxes were not adequate in all material respects for the satisfaction of
Federal, state and local taxes for the period from November 1, 1995 to and
including the Exchange Date and for the final taxable year of MuniYield New York
Insured III ending upon liquidation or that MuniYield New York Insured III had
not qualified as a regulated investment company for Federal income tax purposes
for the period from November 1, 1995 through liquidation of MuniYield New York
Insured III.
 
     (f) That there shall not be any material litigation pending with respect to

included or incorporated by reference in the N-14 Registration Statement and

unaudited interim financial statements and unaudited supplementary information
of MuniVest New York Insured included in the N-14 Registration Statement, and
inquiries of certain officials of MuniVest New York Insured responsible for
financial and accounting matters, nothing came to their attention that caused

unaudited supplementary information do not comply as to form in all material
respects with the applicable accounting requirements of the 1933 Act and the
published rules and regulations thereunder, (b) such unaudited financial
statements are not fairly presented in conformity with generally accepted

(with the exception of performance comparisons, if any), if any, has been
obtained from the accounting records of MuniVest New York Insured or from

instituted or, to the knowledge of MuniVest New York Insured or MuniYield New

under Section 25(c) of the 1940 Act, no other legal, administrative or other

                        ECONOMIC CONDITIONS IN NEW YORK
 
     The following information is a brief summary of factors affecting the
economy of the State of New York and does not purport to be a complete
description of such factors. Other factors will affect issuers. The summary is
based primarily upon one or more publicly available offering statements relating
to debt offerings of state issuers; however, it has not been updated nor will it
be updated during the year. The Funds have not independently verified the
information.
 
     In recent years, New York State (sometimes referred to herein as the
"State" or "New York"), some of its agencies, instrumentalities and public
authorities and certain of its municipalities have faced serious financial
difficulties that could have an adverse effect on the sources of payment for, or
the market value of, the New York Municipal Bonds in which each Fund invests.
 
NEW YORK CITY
 
     General.  More than any other municipality, the fiscal health of New York
City (sometimes referred to as the "City") has a significant effect on the
fiscal health of the State. The national economic downturn which began in July
1990 adversely affected the local economy, which had been declining since late
1989. As a result, the City experienced job losses in 1990 and 1991 and real
Gross City Product ("GCP") fell in those two years. Beginning in calendar year
1992, the improvement in the national economy helped stabilize conditions in the
City. Employment losses moderated toward year-end and real GCP increased,
boosted by strong wage gains. However, after noticeable improvements in the
City's economy during the calendar year 1994, economic growth slowed in calendar
year 1995, and the City's current four-year financial plan assumes that moderate
economic growth will continue through calendar year 2000.
 
     For each of the 1981 through 1995 fiscal years, the City achieved balanced
operating results as reported in accordance with generally accepted accounting
principles ("GAAP"). The City was required to close substantial budget gaps in
recent fiscal years in order to maintain balanced operating results. For the
City's 1995 fiscal year, the City adopted a budget which halted the trend in
recent years of substantial increases in City spending from one year to the
next. There can be no assurance that the City will continue to maintain a
balanced budget as required by State law without additional reductions in City
services or entitlement programs or tax or other revenue increases which could
adversely affect the City's economic base.
 
     Pursuant to the laws of the State, the Mayor is responsible for preparing
the City's four-year financial plan, including the City's current financial plan
for the 1997 through 2000 fiscal years (the "1997-2000 Financial Plan" or the
"City Financial Plan"). The City's projections set forth in the City Financial
Plan are based on various assumptions and contingencies which are uncertain and
which may not materialize. Changes in major assumptions could significantly
affect the City's ability to balance its budget as required by State law and to
meet its annual cash flow and financing requirements.
 
     Implementation of the City Financial Plan is also dependent upon the City's
ability to market its securities successfully in the public credit markets. The
City's financing program for fiscal years 1997 through 2000 contemplates the
issuance of $5.8 billion of general obligation bonds and $4.1 billion of bonds
to be issued by the proposed New York City Infrastructure Finance Authority,
primarily to reconstruct and
 
                                      II-1
   184
 
rehabilitate the City's infrastructure and physical assets and to make capital
investments. The creation of the Infrastructure Finance Authority, which is
subject to the enactment of legislation by the State, is being proposed by the
City as part of the City's effort to avoid certain State constitutional
limitations on the amount of debt the City is authorized to issue. In addition,
the City issues revenue notes and tax anticipation notes to finance its seasonal
working capital requirements. The success of projected public sales of City
bonds and notes will be subject to prevailing market conditions, and no
assurance can be given that such sales will be completed. If the City were
unable to sell its general obligation bonds and notes, it would be prevented
from meeting its planned operating and capital expenditures.
 
     1997-2000 Financial Plan.  The City Financial Plan for the 1997 through
2000 fiscal years projects revenues and expenditures for the 1997 fiscal year
(July 1, 1996-June 30, 1997) for the City balanced in accordance with GAAP and
reflects proposed actions to close a previously projected budget gap of
approximately $2.6 billion. Such gap closing actions include spending reductions
for Medicaid and welfare programs, City agency spending reductions, additional
State aid, pension and debt service savings and the sale of certain City assets.
The City Financial Plan also sets forth projections for the 1998 through 2000
fiscal years and outlines a proposed gap-closing program to close projected
budget gaps of $1.7 billion, $2.7 billion and $3.4 billion for the 1998 through
2000 fiscal years, respectively, after successful implementation of the gap-
closing program for the 1997 fiscal year.
 
     The City's projections set forth in the City Financial Plan are based on
various assumptions and contingencies which are uncertain and which may not
materialize. Changes in major assumptions could significantly affect the City's
ability to balance its budget as required by State law and to meet its annual
cash flow and financing requirements. Such assumptions and contingencies include
the condition of the regional and local economies, the impact on real estate tax
revenues of the real estate market, employment growth, wage increases for City
employees consistent with those assumed in the City Financial Plan, continuation
of interest earnings assumptions for pension fund assets, the ability of the
City's hospital and education entities to maintain balanced budgets, provision
of State and Federal aid, the impact of proposed Federal and State welfare
reforms on City revenues and adoption of the budget by the City Council in
substantially the form submitted by the Mayor. The City Financial Plan also
assumes the timely extension by the State Legislature of the current rate
structures for personal income, corporation and sales taxes imposed by the City.
In addition, the continuing failure of the Federal government to adopt a budget
for its 1996 fiscal year and the continuing failure of the State to adopt its
1996-1997 fiscal year budget could result in a delay or reduction in the receipt
of Federal grants and State aid in the City's 1997 fiscal year.
 
     The City Financial Plan is also subject to the ability of the City to
implement the expenditure reductions, sell the assets and obtain the debt
service savings outlined in the City Financial Plan. In addition, the City may
incur expenditures which exceed those projected in the City Financial Plan.
There can be no assurance that additional gap-closing measures will not be
required to enable the City to achieve a balanced budget in a particular fiscal
year. Certain of the proposed actions are subject to negotiation with the City's
municipal unions. Various other actions proposed for the 1997 through 1999
fiscal years are subject to approval by the Governor and the State Legislature
and the proposed reductions in spending for entitlement programs may be subject
to legal challenge.
 
     The City depends on the State for State aid both to enable the City to
balance its budget and to meet its cash requirements. If the State experiences
revenue shortfalls or spending increases beyond its projections during the
current or subsequent fiscal years, such developments could result in reductions
in anticipated State
 
                                      II-2
   185
 
aid to the City. In addition, there can be no assurance that State budgets in
any given State fiscal year will be adopted by the April 1 statutory deadline
and that there will not be adverse effects on the City's cash flow and
additional City expenditures as a result of such reductions or delays.
 
     The City's financial plans have been the subject of extensive public
comment and criticism. On May 30, 1996, the City Comptroller issued a report
stating that the Executive Budget for the City's 1997 fiscal year includes
budget risks of up to $1.546 billion for the 1997 fiscal year. On June 5, 1996,
the Financial Control Board issued a report on the City Financial Plan which
identified budget risks of $1.2 billion for the 1997 fiscal year. On May 30,
1996, the Office of the State Deputy Comptroller of New York issued a report
which reviewed the Executive Budget for the City's 1997 fiscal year and
concluded that there were potential budget risks of $1.2 billion for the 1997
fiscal year. The report also noted that the Executive Budget achieves budget
balance for the 1997 fiscal year only with the inclusion of approximately $1.4
billion in new recurring resources. It is reasonable to expect that such reports
will continue to be issued and to engender public comment.
 
     Ratings.  As of April 18, 1996, Moody's Investors Service, Inc. ("Moody's")
rated the City's outstanding general obligation bonds "Baa1", Standard & Poor's
Ratings Group ("Standard & Poor's") rated such bonds "BBB+" and Fitch Investors
Service, Inc. ("Fitch") rated such bonds "A-". On February 28, 1996, Fitch
placed the City's general obligation bonds on FitchAlert with negative
implications. On July 10, 1995, Standard & Poor's revised downward its ratings
on outstanding general obligation bonds of the City from "A-" to "BBB+". Such
ratings reflect only the view of Moody's, Standard & Poor's and Fitch, from
which an explanation of the significance of such ratings may be obtained. There
is no assurance that such ratings will continue for any given period of time or
that they will not be revised downward or withdrawn entirely. Any such downward
revision or withdrawal could have an adverse effect on the market prices of City
bonds.
 
     Outstanding Indebtedness.  As of March 31, 1996, the City had approximately
$24.84 billion of long-term debt and as of June 30, 1995, the New York City
Municipal Water Finance Authority (the "Water Authority") has approximately
$6.05 billion of net long-term debt.
 
     Debt service on Water Authority obligations is secured by fees and charges
collected from the users of the City's water and sewer system. State and Federal
regulations require the City's water supply to meet certain standards to avoid
filtration. The City's water supply now meets all technical standards and the
City's current efforts are directed toward protection of the watershed area. The
City has taken the position that increased regulatory, enforcement and other
efforts to protect its water supply, relating to such matters as land use and
sewage treatment, will preserve the high quality of water in the upstate water
supply system and prevent the need for filtration. The U.S. Environmental
Protection Agency has granted the City a waiver of filtration regulations
through 1999. If filtration of the City's water supply is ultimately required,
the capital expenditure required could be between $4 billion and $5 billion.
Such an expenditure could cause significant increases in City water and sewer
charges.
 
     Litigation.  The City is a defendant in a significant number of lawsuits.
Such litigation includes, but is not limited to, routine litigation incidental
to the performance of its governmental and other functions, actions commenced
and claims asserted against the City arising out of alleged constitutional
violations, alleged torts, alleged breaches of contracts and other alleged
violations of law and condemnation proceedings and other tax and miscellaneous
actions. While the ultimate outcome and fiscal impact, if any, on the
proceedings and claims are not currently predictable, adverse determination in
certain of them might have a material adverse
 
                                      II-3
   186
 
effect upon the City's ability to carry out the City Financial Plan. As of June
30, 1995, the City estimated its potential future liability on account of all
outstanding claims to be approximately $2.5 billion.
 
NEW YORK STATE
 
     Current Economic Outlook.  The national economy began to expand in 1991 and
has added over 7 million jobs since early 1992. Although the State has added
approximately 185,000 jobs since November 1992, employment growth in the State
has been hindered during recent years by significant cutbacks in the computer
and instrument manufacturing, utility, defense and banking industries.
 
     The State expects modest economic growth in New York's economy for the 1995
and 1996 calendar years. Overall employment growth is estimated to be 0.7
percent in 1995 and projected at 0.5 percent in 1996 while personal income
growth is expected to be 5.7 percent in 1995 and 4.4 percent in 1996.
 
     1996-1997 Fiscal Year.  As of June 24, 1996, the State has not yet adopted
a budget for the 1996-97 fiscal year, which began on April 1, 1996. Legislation
making interim appropriations for State personal service costs, various grants
to local governments, and certain other items have been submitted by the
Governor and enacted by the Legislature. Appropriations for existing debt
service obligations of the State have been enacted for the entire 1996-97 fiscal
year. The State Senate, the State Assembly and the Governor are engaged in
continuing negotiations, and it is reasonable to expect press reports on their
progress as the budget process continues.
 
     On December 15, 1995, the Governor released the Executive Budget for the
State's 1996-1997 fiscal year (the "Executive Budget"), which the State
Legislature must enact and the Governor must sign in order to become law. The
Executive Budget, as amended, projects balance on a cash basis but identifies a
potential budget gap of approximately $3.9 billion due primarily to the effect
of current and prior year tax reductions and the use of nonrecurring revenues in
the 1995-1996 State Financial Plan. To close the projected gap for the 1996-1997
fiscal year, the Executive Budget projects a significant increase in Federal
Medicaid revenues as well as significant spending reductions in State Medicaid,
welfare, health, mental health and education programs and anticipates the use of
an expected surplus from the 1995-1996 fiscal year. In the event increased
Federal Medicaid revenues do not materialize as projected, the Executive Budget
provides for certain contingencies including additional reductions in State
expenditures, pension and debt service savings and the use of certain
nonrecurring sources of revenue. There can be no assurance that the Executive
Budget be will enacted as proposed, the cost containment, spending reduction and
contingency programs can be implemented as contemplated or the anticipated
increase in Federal aid will materialize as expected.
 
     The Executive Budget is based upon forecasts of national and State economic
activity. Economic forecasts have frequently failed to predict accurately the
timing and magnitude of changes in the national and State economies. Many
uncertainties exist in forecasts of both the national and State economies,
including consumer attitudes toward spending, Federal financial and monetary
policies, the availability of credit and the condition of the world economy,
which could have an adverse effect on the State. There can be no assurance that
the State economy will not experience worse-than-predicted results in the
1996-1997 and subsequent fiscal years, with corresponding material and adverse
effects on the State's projections of receipts and disbursements.
 
     Owing to these and other factors, the State may face substantial potential
budget gaps in future years resulting from a significant disparity between tax
revenues from a lower recurring receipts base and the
 
                                      II-4
   187
 
spending required to maintain State programs at mandated levels. Any such
recurring imbalance would be exacerbated by the use by the State of nonrecurring
resources to achieve budgetary balance in a particular fiscal year. To correct
any recurring budgetary imbalance, the State would need to take significant
actions to align recurring receipts and disbursements in future fiscal years.
There can be no assurance, however, that the State's actions will be sufficient
to preserve budget balances in the then-current or future fiscal years.
 
     The Executive Budget contains actions that provide nonrecurring resources
or savings as well as actions that impose baseline losses of receipts. The
Division of the Budget estimates the net amount of nonrecurring resources used
in the Executive Budget to be at least $1.1 billion. In addition to these
nonrecurring actions, the adoption of a three-year 20% reduction in the State's
personal income tax in 1995 in combination with business tax reductions enacted
in 1994 will reduce State tax receipts by as much as $5.6 billion by the
1997-1998 fiscal year.
 
     Uncertainties with regard to both the economy and potential decisions at
the Federal level add further pressure on future budget balance in New York
State. Specific budget proposals being discussed at the Federal level but not
included in the State's current economic forecast would (if enacted) have a
disproportionately negative impact on the longer-term outlook for the State's
economy as compared to other states.
 
     1995-1996 Fiscal Year.  The State ended its 1995-1996 fiscal year in
balance, with a reported 1995-1996 General Fund cash surplus of $445 million.
Prior to adoption of the State's 1995-1996 fiscal year budget, the State had
projected a potential budget gap of approximately $5 billion, which was closed
primarily through spending reductions, cost containment measures, State agency
actions and local assistance reforms.
 
     1994-1995 Fiscal Year.  In July, 1995, the State Comptroller issued its
audit of the State's 1994-1995 fiscal year prepared in accordance with generally
accepted auditing standards. The State completed its 1994-1995 fiscal year with
a General Fund operating deficit of $1.426 billion, as compared with an
operating surplus of $914 million for the previous fiscal year. The 1994-1995
fiscal year deficit was caused by several factors, including the use of $1.026
billion of the 1993-1994 fiscal year surplus in the 1994-1995 fiscal year and
the adoption of changes in accounting methodologies by the State Comptroller.
 
     Local Government Assistance Corporation.  In 1990, as part of a state
fiscal reform program, legislation was enacted creating the Local Government
Assistance Corporation ("LGAC"), a public benefit corporation empowered to issue
long-term obligations to fund certain payments to local governments
traditionally funded through the State's annual seasonal borrowing. As of June
1995, LGAC has issued bonds to provide net proceeds of $4.7 billion completing
the program. The impact of LGAC's borrowing is that the State is able to meet
its cash flow needs without relying on short-term seasonal borrowing.
 
     Financing Activities.  State financing activities include general
obligation debt of the State and State-guaranteed debt, to which the full faith
and credit of the State has been pledged, as well as lease-purchase and
contractual-obligation financings, moral obligation financings and other
financings through public authorities and municipalities, where the State's
obligation to make payments for debt service is generally subject to annual
appropriation by the State Legislature.
 
     As of March 31, 1995, the total amount of outstanding general obligation
debt was approximately $5.181 billion, including $149 million in Bond
Anticipation Notes; the total amount of moral obligation debt
 
                                      II-5
   188
 
was approximately $7.01 billion; and $17.98 billion of bonds issued primarily in
connection with lease-purchase and contractual-obligation financing of State
capital programs were outstanding.
 
     Public Authorities.  The fiscal stability of the State is related, in part,
to the fiscal stability of its public authorities. The State anticipates that
its capital programs will be financed, in part, by State and public authorities
borrowings in the 1996-1997 fiscal year. Public authorities are not subject to
the constitutional restrictions on the incurrence of debt which apply to the
State itself, and may issue bonds and notes within the amounts of, and as
otherwise restricted by, their legislative authorization. As of September 30,
1994, the latest data available, there were 18 public authorities that had
outstanding debt of $100 million or more and the aggregate outstanding debt,
including refunding bonds, of these 18 public authorities was $70.3 billion. The
State's access to the public credit markets could be impaired and the market
price of its outstanding debt may be adversely affected, if any of its public
authorities were to default in their respective obligations.
 
     Ratings.  Currently, Moody's, Standard & Poor's and Fitch rate New York
State's outstanding general obligation bonds "A", "A-" and "A+", respectively.
Ratings reflect only the respective views of such organizations, and an
explanation of the significance of such ratings must be obtained from the rating
agency furnishing the same. There is no assurance that a particular rating will
continue for any given period of time or that any such rating will not be
revised downward or withdrawn entirely if, in the judgment of the agency
originally establishing the rating, circumstances so warrant. A downward
revision or withdrawal of such ratings may have an effect on the market price of
the New York Municipal Bonds in which each Fund invests.
 
     Litigation.  The State is a defendant in numerous legal proceedings
including, but not limited to, claims asserted against the State arising from
alleged torts, alleged breaches of contracts, condemnation proceedings and other
alleged violations of State and Federal laws. State programs are frequently
challenged on State and Federal constitutional grounds. Adverse developments in
legal proceedings or the initiation of new proceedings could affect the ability
of the State to maintain a balanced State Financial Plan in any given fiscal
year. The State believes that the Executive Budget includes sufficient reserves
for the payment of judgments that may be required during the 1996-1997 fiscal
year. There can be no assurance, however, that an adverse decision in one or
more legal proceedings would not exceed the amount of such reserves for the
payment of judgments or materially impair the State's financial operations.
 
     Other Localities.  Certain localities in addition to the City could have
financial problems leading to requests for additional State assistance during
the State's 1996-1997 fiscal year and thereafter. The potential impact on the
State of such actions by localities is not included in the projections of the
State receipts and disbursements in the State's 1996-1997 fiscal year.
 
     Fiscal difficulties experienced by the City of Yonkers ("Yonkers") resulted
in the creation of the Financial Control Board for Yonkers (the "Yonkers Board")
by the State in 1984. The Yonkers Board is charged with oversight of the fiscal
affairs of Yonkers. Future actions taken by the Governor or the State
Legislature to assist Yonkers could result in allocation of State resources in
amounts that cannot yet be determined.

                RATINGS OF MUNICIPAL BONDS AND COMMERCIAL PAPER
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("MOODY'S") MUNICIPAL BOND
RATINGS
 
     Aaa -- Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge". Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
     Aa -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
 
     A -- Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may be
present which suggest a susceptibility to impairment some time in the future.
 
     Baa -- Bonds which are rated Baa are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present, but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
     Ba -- Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
     B -- Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.
 
     Caa -- Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.
 
     Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
     Con. (...) -- Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally. These are
bonds secured by (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operation experience, (c) rentals which begin when
 
                                      III-1
   190
 
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.
 
     Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
A1, Baa1, Ba1 and B1.
 
     Short-term Notes and Variable Rate Demand Obligations:  The four ratings of
Moody's for short-term notes and VRDOs are MIG-1/VMIG-1, MIG-2/VMIG-2,
MIG-3/VMIG-3, and MIG-4/VMIG-4; MIG-1/VMIG-1 denotes "best quality, enjoying
strong protection from established cash flows"; MIG-2/VMIG-2 denotes "high
quality" with "ample margins of protection"; MIG-3/VMIG-3 instruments are of
"favorable quality . . . but lacking the undeniable strength of the preceding
grades"; MIG-4/VMIG-4 instruments are of "adequate quality, carrying specific
risk but having protection . . . and not distinctly or predominantly
speculative".
 
DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS
 
     Moody's Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers:
 
     Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics: leading
market positions in well established industries; high rates of return on funds
employed; conservative capitalization structures with moderate reliance on debt
and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and with established access
to a range of financial markets and assured sources of alternate liquidity.
 
     Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
     Issuers rated Prime-3 (or related supporting institutions) have an
acceptable capacity for repayment of short-term promissory obligations. The
effects of industry characteristics and market composition may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.
 
     Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
DESCRIPTION OF STANDARD & POOR'S RATINGS GROUP'S ("STANDARD & POOR'S") MUNICIPAL
DEBT RATINGS
 
     A Standard & Poor's municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
                                      III-2
   191
 
     The debt rating is not a recommendation to purchase, sell or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.
 
     The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources Standard & Poor's considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information, or for other reasons.
 
     The ratings are based, in varying degrees, on the following considerations:
 
            I. Likelihood of default-capacity and willingness of the obligor as
     to the timely payment of interest and repayment of principal in accordance
     with the terms of the obligation;
 
           II. Nature of and provisions of the obligation;
 
          III. Protection afforded to, and relative position of, the obligation
     in the event of bankruptcy, reorganization or other arrangement under the
     laws of bankruptcy and other laws affecting creditors' rights.
 
        AAA -- Debt rated "AAA" has the highest rating assigned by Standard &
        Poor's. Capacity to pay interest and repay principal is extremely
        strong.
 
        AA -- Debt rated "AA" has a very strong capacity to pay interest and
        repay principal and differs from the highest rated issues only in small
        degree.
 
        A -- Debt rated "A" has a strong capacity to pay interest and repay
        principal although they are somewhat more susceptible to the adverse
        effects of changes in circumstances and economic conditions than debt in
        higher-rated categories.
 
        BBB -- Debt rated "BBB" is regarded as having an adequate capacity to
        pay interest and repay principal. Whereas it normally exhibits adequate
        protection parameters, adverse economic conditions or changing
        circumstances are more likely to lead to a weakened capacity to pay
        interest and repay principal for debt in this category than for debt in
        higher-rated categories.
 
        BB, B, CCC, CC, C -- Debt rated "BB", "B", "CCC", "CC" and "C" is
        regarded, on balance, as predominately speculative with respect to
        capacity to pay interest and repay principal in accordance with the
        terms of the obligation. "BB" indicates the lowest degree of speculation
        and "C" the highest degree of speculation. While such debt will likely
        have some quality and protective characteristics, these are outweighed
        by large uncertainties or major risk exposures to adverse conditions.
 
        BB -- Debt rated "BB" has less near-term vulnerability to default than
        other speculative issues. However, it faces major ongoing uncertainties
        or exposure to adverse business, financial, or economic conditions which
        could lead to inadequate capacity to meet timely interest and principal
        payments. The "BB" rating category is also used for debt subordinated to
        senior debt that is assigned an actual or implied "BBB-" rating.
 
        B -- Debt rated "B" has a greater vulnerability to default but currently
        has the capacity to meet interest payments and principal repayments.
        Adverse business, financial, or economic conditions will
 
                                      III-3
   192
 
        likely impair capacity or willingness to pay interest and repay
        principal. The "B" rating category is also used for debt subordinated to
        senior debt that is assigned an actual or implied "BB" or "BB-" rating.
 
        CCC -- Debt rated "CCC" has a currently identifiable vulnerability to
        default, and is dependent upon favorable business, financial and
        economic conditions to meet timely payment of interest and repayment of
        principal. In the event of adverse business, financial, or economic
        conditions, it is not likely to have the capacity to pay interest and
        repay principal. The "CCC" rating category is also used for debt
        subordinated to senior debt that is assigned an actual or implied "B" or
        "B-" rating.
 
        CC -- The rating "CC" is typically applied to debt subordinated to
        senior debt that is assigned an actual or implied "CCC" rating.
 
        C -- The rating "C" is typically applied to debt subordinated to senior
        debt which is assigned an actual or implied "CCC-" debt rating. The "C"
        rating may be used to cover a situation where a bankruptcy petition has
        been filed but debt service payments are continued.
 
        C1 -- The rating "C1" is reserved for income bonds on which no interest
        is being paid.
 
        D -- Debt rated "D" is in payment default. The "D" rating category is
        used when interest payments or principal payments are not made on the
        date due even if the applicable grace period has not expired, unless
        Standard & Poor's believes that such payments will be made during such
        grace period. The "D" rating also will be used upon the filing of a
        bankruptcy petition if debt service payments are jeopardized.
 
     Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.
 
DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS
 
     A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into several categories, ranging from "A-1" for the
highest quality obligations to "D" for the lowest. The three designations in the
"A" category are as follows:
 
          A-1 -- This highest category indicates that the degree of safety
     regarding timely payment is strong. Those issues determined to possess
     extremely strong safety characteristics are denoted with a "+" designation.
 
          A-2 -- Capacity for timely payment on issues with this designation is
     satisfactory. However, the relative degree of safety is not as high as for
     issues designated "A-1".
 
          A-3 -- Issues carrying this designation have adequate capacity for
     timely payment. They are, however, more vulnerable to the adverse effects
     of changes in circumstances than obligations carrying the higher
     designations.
 
          B -- Issues rated "B" are regarded as having only speculative capacity
     for timely payment.
 
          C -- This rating is assigned to short-term debt obligations with a
     doubtful capacity for payment.
 
                                      III-4
   193
 
          D -- Debt rated "D" is in payment default. The "D" rating category is
     used when interest payments or principal payments are not made on the date
     due, even if the applicable grace period has not expired, unless Standard &
     Poor's believes that such payments will be made during such grace period.
 
     A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained from other sources it considers reliable. The
ratings may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of, such information.
 
     A Standard & Poor's municipal note rating reflects the liquidity concerns
and market access risks unique to such notes. Notes due in three years or less
will likely receive a note rating. Notes maturing beyond three years will most
likely receive a long-term debt rating. The following criteria will be used in
making that assessment.
 
     Amortization schedule (the larger the final maturity relative to other
maturities, the more likely it will be treated as a note).
 
     Source of payment (the more dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note).
 
     Note rating symbols are as follows:
 
     SP-1  A very strong, or strong, capacity to pay principal and interest.
           Issues that possess overwhelming safety characteristics will be given
           a "+" designation.
 
     SP-2  A satisfactory capacity to pay principal and interest.
 
     SP-3  A speculative capacity to pay principal and interest.
 
DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S ("FITCH") INVESTMENT GRADE BOND
RATINGS
 
     Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.
 
     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength and credit quality.
 
     Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guarantees unless otherwise indicated.
 
     Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
     Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
                                      III-5
   194
 
     Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.
 
          AAA -- Bonds considered to be investment grade and of the highest
     credit quality. The obligor has an exceptionally strong ability to pay
     interest and repay principal, which is unlikely to be affected by
     reasonably foreseeable events.
 
          AA -- Bonds considered to be investment grade and of very high credit
     quality. The obligor's ability to pay interest and repay principal is very
     strong, although not quite as strong as bonds rated "AAA". Because bonds
     rated in the "AAA" and "AA" categories are not significantly vulnerable to
     foreseeable future developments, short-term debt of these issuers is
     generally rated "F-1+".
 
          A -- Bonds considered to be investment grade and of high credit
     quality. The obligor's ability to pay interest and repay principal is
     considered to be strong, but may be more vulnerable to adverse changes in
     economic conditions and circumstances than bonds with higher ratings.
 
          BBB -- Bonds considered to be investment grade and of satisfactory
     credit quality. The obligor's ability to pay interest and repay principal
     is considered to be adequate. Adverse changes in economic conditions and
     circumstances, however, are more likely to have adverse impact on these
     bonds, and therefore impair timely payment. The likelihood that the ratings
     of these bonds will fall below investment grade is higher than for bonds
     with higher ratings.
 
     Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol
to indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "AAA" category.
 
Credit Trend Indicator: Credit trend indicators show whether credit fundamentals
are improving, stable, declining, or uncertain, as follows:
 

                        
              Improving       [ARROW UP]
              Stable          [ARROW LEFT/RIGHT]
              Declining       [ARROW DOWN]
              Uncertain       [ARROW UP/DOWN]

 
     Credit trend indicators are not predictions that any rating change will
occur, and have a longer-term time frame than issues placed on FitchAlert.
 
NR indicates that Fitch does not rate the specific issue.
 
     CONDITIONAL:  A conditional rating is premised on the successful completion
of a project or the occurrence of a specific event.
 
     SUSPENDED:  A rating is suspended when Fitch deems the amount of
information available from the issuer to be inadequate for rating purposes.
 
     WITHDRAWN:  A rating will be withdrawn when an issue matures or is called
or refinanced and, at Fitch's discretion, when an issuer fails to furnish proper
and timely information.
 
                                      III-6
   195
 
FITCHALERT:  Ratings are placed on FitchAlert to notify investors of an
occurrence that is likely to result in a rating change and the likely direction
of such change. These are designated as "Positive" indicating a potential
upgrade, "Negative" for potential downgrade, or "Evolving" where ratings may be
raised or lowered. FitchAlert is relatively short-term, and should be resolved
within three to 12 months.
 
DESCRIPTION OF FITCH'S SPECULATIVE GRADE BOND RATINGS
 
     Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or liquidation.
 
     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.
 
     Bonds that have the same rating are of similar but not necessarily
identical credit quality since rating categories cannot fully reflect the
differences in degrees of credit risk.
 
     BB -- Bonds are considered speculative. The obligor's ability to pay
interest and repay principal may be affected over time by adverse economic
changes. However, business and financial alternatives can be identified which
could assist the obligor in satisfying its debt service requirements.
 
     B -- Bonds are considered highly speculative. While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal and interest reflects the obligor's limited margin of
safety and the need for reasonable business and economic activity throughout the
life of the issue.
 
     CCC -- Bonds have certain identifiable characteristics which, if not
remedied, may lead to default. The ability to meet obligations requires an
advantageous business and economic environment.
 
     CC -- Bonds are minimally protected. Default in payment of interest and/or
principal seems probable over time.
 
     C -- Bonds are in imminent default in payment of interest or principal.
 
     DDD, DD, and D -- Bonds are in default on interest and/or principal
payments. Such bonds are extremely speculative and should be valued on the basis
of their ultimate recovery value in liquidation or reorganization of the
obligor. "DDD" represents the highest potential for recovery on these bonds, and
"D" represents the lowest potential for recovery.
 
     Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol
to indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "DDD," "DD," or "D" categories.
 
                                      III-7

DESCRIPTION OF FITCH'S INVESTMENT GRADE SHORT-TERM RATINGS
 
     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.
 
     The short-term rating places greater emphasis than a long-term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.
 
     Fitch short-term ratings are as follows:
 

            
         F-1+     Exceptionally Strong Credit Quality.  Issues assigned this rating are
                  regarded as having the strongest degree of assurance for timely payment.
         F-1      Very Strong Credit Quality.  Issues assigned this rating reflect an
                  assurance of timely payment only slightly less in degree than issues rated
                  "F-1+".
         F-2      Good Credit Quality.  Issues assigned this rating have a satisfactory
                  degree of assurance for timely payment, but the margin of safety is not as
                  great as for issues assigned "F-1+" and "F-1" ratings.
         F-3      Fair Credit Quality.  Issues assigned this rating have characteristics
                  suggesting that the degree of assurance for timely payment is adequate;
                  however, near-term adverse changes could cause these securities to be rated
                  below investment grade.
         F-4      Weak Credit Quality.  Issues assigned this rating have characteristics
                  suggesting a minimal degree of assurance for timely payment and are
                  vulnerable to near-term adverse changes in financial and economic
                  conditions.
         D        Default.  Issues assigned this rating are in actual or imminent payment
                  default.
         LOC      The symbol "LOC" indicates that the rating is based on a letter of credit
                  issued by a commercial bank.

                                                                      EXHIBIT IV
 
                              PORTFOLIO INSURANCE
 
     Set forth below is further information with respect to the Mutual Fund
Insurance Policies (the "Policies") which each Fund may obtain from several
insurance companies with respect to insured Municipal Bonds held by the Fund.
Each Fund has no obligation to obtain any such Policies and the terms of any
Policies actually obtained may vary significantly from the terms described
below.
 
     In determining eligibility for insurance, insurance companies will apply
their own standards which correspond generally to the standards they normally
use in establishing the insurability of new issues of Municipal Bonds and which
are not necessarily the criteria which would be used in regard to the purchase
of such bonds by the Funds. The Policies do not insure (i) municipal securities
ineligible for insurance and (ii) municipal securities no longer owned by a
Fund.
 
     The Policies do not guarantee the market value of the insured Municipal
Bonds or the value of the shares of the Funds. In addition, if the provider of
an original issuance insurance policy is unable to meet its obligations under
such policy or if the rating assigned to the insurance claims-paying ability of
any such insurer deteriorates, the insurance company will not have any
obligation to insure any issue held by a Fund which is adversely affected by
either of the above described events. In addition to the payment of premiums,
the Policies may require that a Fund notify the insurance company as to all
Municipal Bonds in the Fund's portfolio and permit the insurance company to
audit their records. The insurance premiums will be payable monthly by each Fund
in accordance with a premium schedule to be furnished by the insurance company
at the time the Policies are issued. Premiums are based upon the amounts covered
and the composition of the portfolio.
 
     The insurance companies will have insurance claims-paying ability ratings
of AAA from Standard & Poor's Ratings Group ("S&P"), Aaa from Moody's Investors
Service, Inc. ("Moody's") or AAA from Fitch Investors Service, Inc. ("Fitch").
 
     An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with the terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P.
Capacity to honor insurance contracts is adjudged by S&P to be extremely strong
and highly likely to remain so over a long period of time. A Moody's insurance
claims-paying ability rating is an opinion of the ability of an insurance
company to repay punctually senior policyholder obligations and claims. An
insurer with an insurance claims-paying ability rating of Aaa is adjudged by
Moody's to be of the best quality. In the opinion of Moody's, the policy
obligations of an insurance company with an insurance claims-paying ability
rating of Aaa carry the smallest degree of credit risk and, while the financial
strength of these companies is likely to change, such changes as can be
visualized are most unlikely to impair the company's fundamentally strong
position. A Fitch insurance claims-paying ability rating provides an assessment
of an insurance company's financial strength and, therefore, its ability to pay
policy and contract claims under the terms indicated. An insurer with an
insurance claims-paying ability rating of AAA has the highest rating assigned by
Fitch. The ability to pay claims is adjudged by Fitch to be extremely strong for
insurance companies with this highest rating. In the opinion of Fitch,
foreseeable business and economic risk factors should not have any material
adverse impact on the ability of these insurers to pay claims. In Fitch's
opinion, profitability, overall balance sheet strength,
 
                                      IV-1
   198
 
capitalization and liquidity are all at very secure levels and are unlikely to
be affected by potential adverse underwriting, investment or cyclical events.
 
     An insurance claims-paying ability rating by S&P, Moody's or Fitch does not
constitute an opinion on any specific contract in that such an opinion can only
be rendered upon the review of the specific insurance contract. Furthermore, an
insurance claims-paying ability rating does not take into account deductibles,
surrender or cancellation penalties or the timeliness of payment; nor does it
address the ability of a company to meet nonpolicy obligations (i.e. debt
contracts.)
 
     The assignment of ratings by S&P, Moody's or Fitch to debt issues that are
fully or partially supported by insurance policies, contracts or guarantees is a
separate process from the determination of claims-paying ability ratings. The
likelihood of a timely flow of funds from the insurer to the trustee for the
bondholders is a key element in the rating determination for such debt issues.

                                     PART C
 
                               OTHER INFORMATION
 
ITEM 15.  INDEMNIFICATION.
 
     Section 2-418 of the General Corporation Law of the State of Maryland,
Article VI of the Registrant's Articles of Incorporation, Article VI of the
Registrant's By-Laws and the Registrant's Investment Advisory Agreement with
Fund Asset Management, Inc. (now known as Fund Asset Management, L.P.; the
"Investment Adviser") provide for indemnification.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be provided to directors,
officers and controlling persons of each Fund, pursuant to the foregoing
provisions or otherwise, each Fund has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and, therefore, is unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by a Fund of expenses incurred or paid by a director, officer or
controlling person of the Registrant in connection with any successful defense
of any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant, unless in the opinion of its counsel the matter has been settled by
controlling precedent, will submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     Reference is made to (i) Section Six of the Purchase Agreement relating to
the Registrant's Common Stock, a form of which previously was filed as an
exhibit to the Common Stock Registration Statement (as defined below), and (ii)
Section Seven of the Purchase Agreement relating to the Registrant's AMPS, a
form of which previously was filed as an exhibit to the AMPS Registration
Statement (as defined below), for provisions relating to the indemnification of
the underwriter.
