NEW YORK SERIES PORTFOLIO--RISK/RETURN SUMMARY

<TABLE>
<C>  <S>
 1.  WHAT ARE THE FUND'S OBJECTIVES?
  -  The Fund seeks interest income that is
     exempt from regular federal income taxes
     by investing in a fixed portfolio
     consisting primarily of long term
     municipal bonds with an estimated
     average life of about 16 years, issued
     by or on behalf of the State of New York
     or its local governments and
     authorities.

  -  The Fund seeks to reduce fluctuations in
     the value of the bonds (and minimize the
     risk of losing money) through the
     repurchase commitments described below.

 2.  WHAT ARE MUNICIPAL REVENUE BONDS?
     Municipal industrial development revenue
     bonds are bonds issued by states,
     municipalities and public authorities to
     finance the cost of buying, building or
     improving various projects intended to
     generate revenue, such as airport,
     healthcare, housing and municipal
     utilities. Generally, payments on these
     bonds depend solely on the revenues
     generated by the project, excise taxes
     or state appropriations, and are not
     backed by the government's taxing power.

 3.  WHAT IS THE FUND'S INVESTMENT STRATEGY?
  -  The Fund plans to hold to maturity 74
     collateralized tax-exempt municipal
     bonds with an aggregate face amount of
     $54,342,695.
  -  The Fund is a unit investment trust
     which means that, unlike a mutual fund,
     the Portfolio is not managed.
  -  The approximate percentage of the
     Portfolio backed by each Seller's
     repurchase commitments is:
</TABLE>

    Astoria Federal                                                          88%
    The Dime Savings Bank                                                     5%
    Home Savings Bank                                                         7%

<TABLE>
<C>  <S>
  -  The bonds were initially acquired from
     savings banks (the Sellers), which had
     held the bonds in their own portfolios.
</TABLE>

<TABLE>
<C>  <S>
     The Portfolio consists of 100%
     collateralized municipal bonds.
</TABLE>

<TABLE>
<C>  <S>
  -  Each Seller has agreed to repurchase on
     14 calendar day's notice any of the bonds
     sold by it to the Fund if:
     -- the Fund needs to sell bonds to meet
        redemptions of units;
     -- the issuer of a bond fails to make
        payments when due;
     -- the interest on a bond becomes
     taxable; and
     -- insolvency proceedings are commenced
     by or against the Seller, or it fails to
        meet its collateral requirements.
</TABLE>

<TABLE>
<C>  <S>
  -  Each Seller has also agreed to repurchase
     its bonds on scheduled disposition dates.
  -  The collateral securing the Sellers'
     repurchase commitments may include:
     -- Ginnie Maes, Fannie Maes and Freddie
        Macs;
     -- mortgages;
     -- municipal obligations;
     -- corporate obligations;
     -- U.S. government securities; and
     -- cash.
  -  You should rely on the collateral for the
     performance of the repurchase commitments
     rather than on the financial position of
     the Sellers.
</TABLE>

<TABLE>
<C>  <S>
 4.  WHAT ARE THE SIGNIFICANT RISKS?
     YOU CAN LOSE MONEY BY INVESTING IN THE
     FUND. THIS CAN HAPPEN FOR VARIOUS
     REASONS, INCLUDING:
  -  Rising interest rates, an issuer's
     worsening financial condition or a
     Seller's failure to meet its repurchase
     commitments can reduce the price of your
     units.
  -  Since the Fund is concentrated in
     collateralized municipal bonds adverse
     developments in this sector may affect
     the value of your units.
  -  Assuming no changes in interest rates,
     when you sell your units, they will
     generally be worth less than your cost
     because your cost included a sales fee.
</TABLE>

                                       3
<PAGE>

<TABLE>
<C>  <S>
  -  The Fund could receive early returns of
     principal if mortgages underlying some
     of the bonds are prepaid, if it becomes
     necessary to liquidate the collateral or
     if bonds are called or sold before they
     mature. If this happens your income will
     decline and you may not be able to
     reinvest the money you receive at as
     high a yield or as long a maturity.
  -  13% of the bonds are currently callable.

     ALSO, THE PORTFOLIO IS CONCENTRATED IN
     BONDS OF NEW YORK SO IT IS LESS
     DIVERSIFIED THAN A NATIONAL FUND AND IS
     SUBJECT TO RISKS PARTICULAR TO NEW YORK
     WHICH ARE BRIEFLY DESCRIBED UNDER STATE
     CONCENTRATION RISKS LATER IN THIS
     PROSPECTUS.

 5.  IS THIS FUND APPROPRIATE FOR YOU?

     Yes, if you want federally tax-free
     income. You will benefit from a
     professionally selected and supervised
     portfolio whose risk is reduced by
     investing in bonds backed by
     collateralized repurchase commitments.
     The Fund is NOT appropriate for you if
     you want a speculative investment that
     changes to take advantage of market
     movements, if you do not want a
     tax-advantaged investment or if you
     cannot tolerate any risk.

 7.  IS THE FUND MANAGED?

     Unlike a mutual fund, the Fund is not
     managed and bonds are not sold because of
     market changes. Rather, experienced
     Defined Asset Funds financial analysts
     regularly review the bonds in the Fund.
     The Fund may sell a bond if certain
     adverse credit or other conditions exist.

 8.  HOW DO I BUY UNITS?

     The minimum investment is one unit.

     You can buy units from any of the
     Sponsors and other broker-dealers. The
     Sponsors are listed later in this
     prospectus. Some banks may offer units
     for sale through special arrangements
     with the Sponsors, although certain legal
     restrictions may apply.

     UNIT PRICE PER UNIT               $355.42
     (as of October 29, 1999)

     Unit price is based on the net asset
     value of the Fund plus the sales fee. An
     amount equal to any principal cash, as
     well as net accrued but undistributed
     interest on the unit, is added to the
     unit price. An independent evaluator
     prices the bonds at 3:30 p.m. Eastern
     time every business day. Unit price
     changes every day with changes in the
     prices of the bonds in the Fund.

 9.  HOW DO I SELL UNITS?

     You may sell your units at any time to
     any Sponsor or the Trustee for the net
     asset value determined at the close of
     business on the date of sale. You will
     not pay any other fee when you sell your
     units.

10.  HOW ARE DISTRIBUTIONS MADE AND TAXED?

     The Fund pays income monthly.

     In the opinion of bond counsel when each
     bond was issued, interest on the bonds in
     this Fund is generally 100% exempt from
     regular federal income tax.

     You will also receive principal payments
     if bonds are sold or called or mature,
     when the cash available is more than
     $5.00 per unit. You will be subject to
     tax on any gain realized by the Fund on
     the disposition of bonds.

<C>  <S>
11.  WHAT OTHER SERVICES ARE AVAILABLE?

     REINVESTMENT
     You will receive your income in cash
     unless you choose to compound your
     income by reinvesting at no sales fee in
     the Municipal Fund Investment
     Accumulation Program, Inc. This Program
     is an open-end mutual fund with a
     comparable investment objective. Income
     from this Program will generally be
     subject to state and local income taxes.
     FOR MORE COMPLETE INFORMATION ABOUT THE
     PROGRAM, INCLUDING CHARGES AND FEES, ASK
     THE TRUSTEE FOR THE PROGRAM'S
     PROSPECTUS. READ IT CAREFULLY BEFORE YOU
     INVEST. THE TRUSTEE MUST RECEIVE YOUR
     WRITTEN ELECTION TO REINVEST AT LEAST 10
     DAYS BEFORE THE RECORD DAY OF AN INCOME
     PAYMENT.

     EXCHANGE PRIVILEGES
     You may exchange units of this Fund for
     units of certain other Defined Asset
     Funds. You may also exchange into this
     Fund from certain other funds. We charge
     a reduced sales fee on most exchanges.

To compare the yield of a taxable security with the yield of a tax-free
security, find your taxable income and read across. The table incorporates 2000
federal and applicable State (and City) income tax rates and assumes that all
income would otherwise be taxed at the investor's highest tax rate. Yield
figures are for example only.

*Based upon net amount subject to federal income tax after deductions and
exemptions. This table does not reflect the possible effect of other tax
factors, such as alternative minimum tax, personal exemptions, the phase out of
exemptions, itemized deductions or the possible partial disallowance of
deductions. Consequently, investors are urged to consult their own tax advisers
in this regard.

WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

MONTHLY INCOME

The Fund will pay you regular monthly income. Your monthly income may vary
because of:
  - elimination of one or more bonds from the Fund's portfolio because of calls,
    redemptions or sales;
  - a change in the Fund's expenses; or
  - the failure by a bond's issuer to pay interest.

Changes in interest rates generally will not affect your income because the
portfolio is fixed.

Along with your income, you will receive your share of any available bond
principal.

RETURN FIGURES

We cannot predict your actual return, which will vary with unit price, how long
you hold your investment and changes in the portfolio, interest income and
expenses.

ESTIMATED CURRENT RETURN equals the estimated annual cash to be received from
the bonds in the Fund less estimated annual Fund expenses, divided by the Unit
Price (including the maximum sales fee):

<TABLE>
<S>              <C>  <C>
Estimated Annual         Estimated
Interest Income   -   Annual Expenses
- -------------------------------------
             Unit Price
</TABLE>

ESTIMATED LONG TERM RETURN is a measure of the estimated return over the
estimated life of the Fund. Unlike Estimated Current Return, Estimated Long Term
Return reflects maturities, discounts and premiums of the bonds in the Fund. It
is an average of the yields to maturity (or in certain cases, to an earlier call
date) of the individual bonds in the portfolio, adjusted to reflect the Fund's
maximum sales fee and estimated expenses. We calculate the average yield for the
portfolio by weighting each bond's yield by its market value and the time
remaining to the call or maturity date.

Yields on individual bonds depend on many factors including general conditions
of the bond markets, the size of a particular offering and the maturity and
quality rating of the particular issues. Yields can vary among bonds with
similar maturities, coupons and ratings.

These return quotations are designed to be comparative rather than predictive.

RECORDS AND REPORTS

You will receive:
- - a monthly statement of income payments and any principal payments;
- - a notice from the Trustee when new bonds are deposited in exchange or
  substitution for bonds originally deposited;
- - an annual report on Fund activity; and
- - annual tax information. THIS WILL ALSO BE SENT TO THE IRS. YOU MUST REPORT THE
  AMOUNT OF TAX-EXEMPT INTEREST RECEIVED DURING THE YEAR.

You may request:
- - copies of bond evaluations to enable you to comply with federal and state tax
  reporting requirements; and
- - audited financial statements of the Fund.

You may inspect records of Fund transactions at the Trustee's office during
regular business hours.

                                       6
<PAGE>
THE RISKS YOU FACE

INTEREST RATE RISK

Investing involves risks, including the risk that your investment will decline
in value if interest rates rise. Generally, bonds with longer maturities will
change in value more than bonds with shorter maturities. Bonds in the Fund are
more likely to be called when interest rates decline. This would result in early
returns of principal to you and may result in early termination of the Fund. Of
course, we cannot predict how interest rates may change.

CALL RISK

Some of the bonds in this Fund are currently callable by the issuer.

If the bonds are called, your income will decline and you may not be able to
reinvest the money you receive at as high a yield or as long a maturity. An
early call at par of a premium bond will reduce your return.

REDUCED DIVERSIFICATION RISK

If many investors sell their units, the Fund will have to sell bonds. This could
reduce the diversification of your investment and increase your share of Fund
expenses.

LIQUIDITY RISK

You can always sell back your units, but we cannot assure you that a liquid
trading market will always exist for the bonds in the portfolio, especially
since current law may restrict the Fund from selling bonds to any Sponsor. The
bonds will generally trade in the over-the-counter market. The value of the
bonds, and of your investment, may be reduced if trading in bonds is limited or
absent.

COLLATERAL RELATED RISK

The Sponsors believe that the collateral is reasonably adequate to support the
repurchase commitments without regard to the ability of the Sellers to meet
these commitments.

You could have all or part of the principal amount of your investment returned
early if insolvency proceedings are commenced by or against a Seller. In that
case, the collateral agent will automatically foreclose on the collateral and,
if necessary, liquidate it and use the proceeds to purchase bonds from the Fund.
You would then receive your share of the proceeds.

The Sponsors have agreed that their sole recourse in the event a Seller fails to
repurchase the bonds as agreed, including as a result of the Seller's
insolvency, will be to exercise available remedies with respect to the
collateral on deposit with the Fund. If the collateral is not enough to cover
the costs resulting from the Seller's default, the Sponsors will be unable to
pursue any deficiency judgment against the Seller.

CONCENTRATION RISK

When a certain type of bond makes up 25% or more of the portfolio, it is said to
be "concentrated" in that bond type, which makes the Portfolio less diversified.

STATE CONCENTRATION RISK

NEW YORK RISKS

GENERALLY

For decades, New York's economy has trailed the rest of the nation. Both the
state and New York City have experienced long-

                                       7
<PAGE>
term structural imbalances between revenues and expenses, and have repeatedly
relied substantially on non-recurring measures to achieve budget balance. The
pressures that contribute to budgetary problems at both the state and local
level include:
  - the high combined state and local tax burden;
  - a decline in manufacturing jobs, leading to above-average unemployment;
  - sensitivity to the financial services industry; and
  - dependence on federal aid.

STATE GOVERNMENT

The State government frequently has difficulty approving budgets on time. Budget
gaps of $3 billion and $5 billion are projected for the next two years. The
State's general obligation bonds are rated A by Standard & Poor's and A2 by
Moody's. There is $37 billion of state-related debt outstanding.

NEW YORK CITY GOVERNMENT

Even though the City had budget surpluses each year from 1981, budget gaps of
about $2 billion are projected for the 2001 and 2002 fiscal years. New York City
faces fiscal pressures from:
  - aging public facilities that need repair or replacement;
  - welfare and medical costs;
  - expiring labor contracts; and
  - a high and increasing debt burden.

The City requires substantial state aid, and its fiscal strength depends heavily
on the securities industry. Its general obligation bonds are rated A- by
Standard & Poor's and A3 by Moody's. $30.7 billion of combined City, MAC and PBC
debt is outstanding, and the City proposes $23 billion of financing over fiscal
1999-2003.

LITIGATION AND LEGISLATION RISKS

We do not know of any pending litigation that might have a material adverse
effect upon the Fund.

Future tax legislation could affect the value of the portfolio by:
  - limiting real property taxes,
  - reducing tax rates,
  - imposing a flat or other form of tax, or
  - exempting investment income from tax.

SELLING OR EXCHANGING UNITS

You can sell your units at any time for a price based on net asset value. Your
net asset value is calculated each business day by:
  - ADDING the value of the bonds, net accrued interest, cash and any other Fund
    assets;
  - SUBTRACTING accrued but unpaid Fund expenses, unreimbursed Trustee advances,
    cash held to buy back units or for distribution to investors and any other
    Fund liabilities; and
  - DIVIDING the result by the number of outstanding units.

Your net asset value when you sell may be more or less than your cost because of
sales fees, market movements and changes in the portfolio.

SPONSORS' SECONDARY MARKET

While we are not obligated to do so, we will buy back units at net asset value
without

                                       8
<PAGE>
any other fee or charge. We may resell the units to other buyers or to the
Trustee. You should consult your financial professional for current market
prices to determine if other broker-dealers or banks are offering higher prices.

We have maintained the secondary market continuously for over 25 years, but we
could discontinue it without prior notice for any business reason.

SELLING UNITS TO THE TRUSTEE

Regardless of whether we maintain a secondary market, you can sell your units to
the Trustee at any time by sending the Trustee a letter (with any outstanding
certificates if you hold Unit certificates). You must properly endorse your
certificates (or execute a written transfer instrument with signatures
guaranteed by an eligible institution). Sometimes, additional documents are
needed such as a trust document, certificate of corporate authority, certificate
of death or appointment as executor, administrator or guardian.

Within seven days after your request and the necessary documents are received,
the Trustee will mail a check to you. Contact the Trustee for additional
information.

As long as we are maintaining a secondary market, the Trustee will sell your
units to us at a price based on net asset value. If there is no secondary
market, the Trustee may sell your units in the over-the-counter market for a
higher price, but it is not obligated to do so. In that case, you will receive
the net proceeds of the sale.

If the Fund does not have cash available to pay you for units you are selling,
the agent for the Sponsors will select bonds to be sold. Bonds will be selected
based on market and credit factors. These sales could be made at times when the
bonds would not otherwise be sold and may result in your receiving less than the
unit par value and also reduce the size and diversity of the Fund.

There could be a delay in paying you for your units:
  - if the New York Stock Exchange is closed (other than customary weekend and
    holiday closings);
  - if the SEC determines that trading on the New York Stock Exchange is
    restricted or that an emergency exists making sale or evaluation of the
    bonds not reasonably practicable; and
  - for any other period permitted by SEC order.

EXCHANGE OPTION

You may exchange units of certain Defined Asset Funds for units of this Fund
with no sales fee. You may exchange units of this Fund for units of certain
other Defined Asset Funds at a reduced sales fee if your investment goals
change. To exchange units, you should talk to your financial professional about
what funds are exchangeable, suitable and currently available.

Normally, an exchange is taxable and you must recognize any gain or loss on the
exchange. However, the IRS may try to disallow a loss if the portfolios of the
two funds are not materially different; you should consult your own tax adviser.

                                       9
<PAGE>
We may amend or terminate this exchange option at any time without notice.

HOW THE FUND WORKS

PRICING

The price of a unit includes interest accrued on the bonds, less expenses, from
the initial most recent Record Day up to, but not including, the settlement
date, which is usually three business days after the purchase date of the unit.

A portion of the price of a unit consists of cash so that the Trustee can
provide you with regular monthly income. When you sell your units you will
receive your share of this cash.

EVALUATIONS

An independent Evaluator values the bonds on each business day (excluding
Saturdays, Sundays and the following holidays as observed by the New York Stock
Exchange: New Year's Day, Presidents' Day, Martin Luther King, Jr. Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas).
Bond values are based on current bid or offer prices for the bonds or comparable
bonds. In the past, the difference between bid and offer prices of publicly
offered tax-exempt bonds has ranged from 0.5% of face amount on actively traded
issues to 3.5% on inactively traded issues; the difference has averaged between
1 and 2%.

INCOME

The Trustee credits interest to an Income Account and other receipts to a
Capital Account. The Trustee may establish a Reserve Account by withdrawing from
these accounts amounts it considers appropriate to pay any material liability.
These accounts do not bear interest.

PLACEMENT FEE

The Sponsors receive a quarterly placement fee from each Seller equal to an
annual percentage ranging from 0.487% to 0.75% of the outstanding principal
amount of bonds sold by that Seller and held by the Fund.

EXPENSES

The Trustee is paid monthly. It also benefits when it holds cash for the Fund in
non-interest bearing accounts. The Trustee may also receive additional amounts:
  - to reimburse the Trustee for the Fund's operating expenses;
  - for extraordinary services and costs of indemnifying the Trustee and the
    Sponsors;
  - costs of actions taken to protect the Fund and other legal fees and
    expenses;
  - expenses for keeping the Fund's registration statement current; and
  - Fund termination expenses and any governmental charges.

The Sponsors are currently reimbursed up to 55 CENTS per $1,000 face amount
annually for providing portfolio supervisory, bookkeeping and administrative
services and for any other expenses properly chargeable to the Fund. Legal,
typsesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Fund's registration statement yearly are also now
chargeable to the Fund. While this fee may exceed the amount of these costs and

                                       10
<PAGE>
expenses attributable to this Fund, the total of these fees for all Series of
Defined Asset Funds will not exceed the aggregate amount attributable to all of
these Series for any calendar year. The Fund also pays the Evaluator's fees.

The Trustee's, Sponsors' and Evaluator's fees may be adjusted for inflation
without investors' approval.

The Sponsors will pay advertising and selling expenses at no charge to the Fund.
If Fund expenses exceed initial estimates, the Fund will owe the excess. The
Trustee has a lien on Fund assets to secure reimbursement of Fund expenses and
may sell bonds if cash is not available.

PORTFOLIO CHANGES

The Sponsors and Trustee are not liable for any default or defect in a bond; if
a contract to buy any bond.

Unlike a mutual fund, the portfolio is designed to remain intact and we may keep
bonds in the portfolio even if their credit quality declines or other adverse
financial circumstances occur. However, we may sell a bond in certain cases if
we believe that certain adverse credit conditions exist or if a bond becomes
taxable.

If we maintain a secondary market in units but are unable to sell the units that
we buy in the secondary market, we will redeem units, which may affect the
composition of the portfolio. Units offered in the secondary market may not
represent the same face amount of bonds that they did originally.

We decide whether or not to offer units for sale that we acquire in the
secondary market after reviewing:
  - diversity of the portfolio;
  - size of the Fund relative to its original size;
  - ratio of Fund expenses to income;
  - current and long-term returns;
  - degree to which units may be selling at a premium over par; and
  - cost of maintaining a current prospectus.

FUND TERMINATION

The Fund will terminate following the stated maturity or sale of the last bond
in the portfolio. The Fund may also terminate earlier with the consent of
investors holding 51% of the units or if total assets of the Fund have fallen
below 40% of the face amount of bonds deposited. We will decide whether to
terminate the Fund early based on the same factors used in deciding whether or
not to offer units in the secondary market.

When the Fund is about to terminate you will receive a notice, and you will be
unable to sell your units after that time. On or shortly before termination, we
will sell any remaining bonds, and you will receive your final distribution. Any
bond that cannot be sold at a reasonable price may continue to be held by the
Trustee in a liquidating trust pending its final sale.

You will pay your share of the expenses associated with termination, including
brokerage costs in selling bonds. This may reduce the amount you receive as your
final distribution.

                                       11
<PAGE>
CERTIFICATES

Certificates for units are issued on request. You may transfer certificates by
complying with the requirements for redeeming certificates, described above. You
can replace lost or mutilated certificates by delivering satisfactory indemnity
and paying the associated costs.

TRUST INDENTURE

The Fund is a "unit investment trust" governed by a Trust Indenture, a contract
among the Sponsors, the Trustee and the Evaluator, which sets forth their duties
and obligations and your rights. A copy of the Indenture is available to you on
request to the Trustee. The following summarizes certain provisions of the
Indenture.

The Sponsors and the Trustee may amend the Indenture without your consent:
  - to cure ambiguities;
  - to correct or supplement any defective or inconsistent provision;
  - to make any amendment required by any governmental agency; or
  - to make other changes determined not to be materially adverse to your best
    interest (as determined by the Sponsors).

Investors holding 51% of the units may amend the Indenture. Every investor must
consent to any amendment that changes the 51% requirement. No amendment may
reduce your interest in the Fund without your written consent.

The Trustee may resign by notifying the Sponsors. The Sponsors may remove the
Trustee without your consent if:
  - it fails to perform its duties and the Sponsors determine that its
    replacement is in your best interest; or
  - it becomes incapable of acting or bankrupt or its affairs are taken over by
    public authorities.

Investors holding 51% of the units may remove the Trustee. The Evaluator may
resign or be removed by the Sponsors and the Trustee without the consent of
investors. The resignation or removal of either becomes effective when a
successor accepts appointment. The Sponsors will try to appoint a successor
promptly; however, if no successor has accepted within 30 days after notice of
resignation, the resigning Trustee or Evaluator may petition a court to appoint
a successor.

Any Sponsor may resign as long as one Sponsor with a net worth of $2 million
remains and agrees to the resignation. The remaining Sponsors and the Trustee
may appoint a replacement. If there is only one Sponsor and it fails to perform
its duties or becomes bankrupt the Trustee may:
  - remove it and appoint a replacement Sponsor;
  - liquidate the Fund; or
  - continue to act as Trustee without a Sponsor.

Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as agent for the
Sponsors.

The Trust Indenture contains customary provisions limiting the liability of the
Trustee, the Sponsors and the Evaluator.

Sponsor buys and sells securities (including investment company shares) for
others (including investment companies) and participates as an underwriter in
various selling groups.

TRUSTEE

The Chase Manhattan Bank, Unit Investment Trust Department, 4 New York
Plaza--6th Floor, New York, New York 10004, is the Trustee. It is supervised by
the Federal Deposit Insurance Corporation, the Board of Governors of the Federal
Reserve System and New York State banking authorities.

UNDERWRITERS' AND SPONSORS' PROFITS

Underwriters receive sales charges when they sell units. The Sponsors also
realized a profit or loss on the initial date of deposit of the bonds. Any cash
made available by you to the Sponsors before the settlement date for those units
may be used in the Sponsors' businesses to the extent permitted by federal law
and may benefit the Sponsors.

A Sponsor or Underwriter may realize profits or sustain losses on bonds in the
Fund which were acquired from underwriting syndicates of which it was a member.

In maintaining a secondary market, the Sponsors will also realize profits or
sustain losses in the amount of any difference between the prices at which they
buy units and the prices at which they resell or redeem them.

PUBLIC DISTRIBUTION

The Sponsors do not intend to qualify units for sale in any foreign countries.
This prospectus does not constitute an offer to sell units in any country where
units cannot lawfully be sold.

CODE OF ETHICS

Merrill Lynch, as agent for the Sponsors, has adopted a code of ethics requiring
preclearance and reporting of personal securities transactions by its employees
with access to information on portfolio transactions. The goal of the code is to
prevent fraud, deception or misconduct against the Fund and to provide
reasonable standards of conduct.

YEAR 2000 ISSUES

Many computer systems were designed in such a way that they may be unable to
distinguish between the year 2000 and the year 1900 (commonly known as the "Year
2000 Problem"). To date we are not aware of any major operational difficulties
resulting from the computer system changes necessary to prepare for the Year
2000. However, there can be no assurance that the Year 2000 Problem will not
adversely affect the issuers of the securities contained in the Portfolio. We
cannot predict whether any impact will be material to the Portfolio as a whole.

TAXES

The following summary describes some of the important income tax consequences of
holding units. It assumes that you are not a dealer in securities, financial
institution, insurance company or other investor with special circumstances. You
should consult your own tax adviser about your particular circumstances.

At the date of issue of each bond, counsel for the issuer delivered an opinion
to the effect that interest on the bond is exempt from regular federal income
tax. However, interest may be subject to state and local taxes and may be taken
into account in determining your preference items for alternative minimum tax
purposes. Neither we nor our counsel have reviewed the issuance of the bonds,
related proceedings or the basis for the opinions of counsel for the issuers. We
cannot assure you that the issuers (or other users) have complied or will comply
with any requirements necessary for a bond to be tax-exempt. If any of the bonds
were determined not to be tax-exempt, you could be required to pay income tax
for current and prior years, and if the Fund were to sell the bond, it might
have to sell it at a substantial discount.

In the opinion of our counsel, under existing law:

GENERAL TREATMENT OF THE FUND AND YOUR INVESTMENT

The Fund will not be taxed as a corporation for federal income tax purposes, and
you will be considered to own directly your share of each bond in the Fund.

Our counsel is of the opinion that the Fund (and therefore the investors, as
discussed below) will be treated as owning the bonds, notwithstanding the
Sellers' repurchase commitments. However, because there are no regulations,
published rulings or judicial

                                       14
<PAGE>
decisions that characterize for federal income tax purposes repurchase
commitments like the Sellers' with respect to the bonds, it is not certain that
the IRS will agree with the conclusions of our counsel. Therefore, it is
possible that the IRS may take actions that might result in the Fund (and
therefore the investors) not being treated as owning the bonds for federal
income tax purposes.

GAIN OR LOSS UPON DISPOSITION

When all or part of your share of a bond is disposed of (for example, when the
Fund sells, exchanges or redeems a bond or when you sell or exchange your
units), you will generally recognize capital gain or loss. While not free from
doubt, the opinion of our counsel is that any capital gain or loss derived from
the Fund will be short-term capital gain or loss regardless of the time that you
have held your Units.

YOUR BASIS IN THE BONDS

You may be required to allocate a portion of your cost for your Units to the
Sellers' repurchase commitment with respect to the bonds. When all or part of
your pro rata portion of a bond is disposed of (and the commitment with respect
to that bond simultaneously is disposed of, lapses or is exercised), both your
basis in your pro rata portion of the bond and your basis in your pro rata
portion of the commitment will be taken into account in determining your overall
net income or loss from the disposition. In some cases, this overall net income
or loss may consist of ordinary income attributable to market discount on the
pro rata portion of the bond and of capital loss attributable to the commitment.
The deductibility of capital losses is subject to limitations. You should
consult your tax adviser in this regard.

If your basis for your pro rata portion of a bond (after giving effect to any
required allocation to the commitment) exceeds the redemption price at maturity
of that bond, you may be considered to have purchased your pro rata portion of
the bond at a "bond premium," which must be amortized.

EXPENSES

If you are not a corporate investor, you will not be entitled to a deduction for
your share of fees and expenses of the Fund. Also, if you borrowed money in
order to purchase or carry your units, you will not be able to deduct the
interest on this borrowing for federal income tax purposes. The IRS may treat
your purchase of units as made with borrowed money even if the money is not
directly traceable to the purchase of units.

STATE AND LOCAL TAXES

Under the income tax laws of the State and City of New York, the Fund will not
be taxed as a corporation. If you are a New York taxpayer, your income from the
Fund will not be tax-exempt in New York except to the extent that the income is
earned on bonds that are tax-exempt for New York purposes. Depending on where
you live, your income from the Fund may be subject to state and local taxation.
You should consult your tax adviser in this regard.

SUPPLEMENTAL INFORMATION

You can receive at no cost supplemental information about the Fund by calling
the Trustee. The supplemental information includes more detailed risk disclosure
about the types of bonds that may be in the Fund's portfolios, general risk
disclosure concerning any insurance securing certain bonds, and general
information about the structure and operation of the Fund. The supplemental
information is also available from the SEC.

          REPORT OF INDEPENDENT ACCOUNTANTS

          The Sponsors, Trustee and Holders
          of Defined Asset Funds - Municipal Investment Trust Fund,
          New York Series - A:

          We have audited the accompanying statement of condition of
          Defined Asset Funds - Municipal Investment Trust Fund, New
          York Series - A, including the portfolio, for the period
          May 1, 1999 to October 31, 1999 and the related statements
          of operations and of changes in net assets for the years
          ended April 30, 1999, 1998 and 1997. These financial
          statements are the responsibility of the Trustee. Our
          responsibility is to express an opinion on these financial
          statements 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 are free
          of material misstatement. An audit includes examining, on a
          test basis, evidence supporting the amounts and disclosures
          in the financial statements. Securities owned at October 31,
          1999, as shown in such portfolio, were confirmed to us by
          The Chase Manhattan Bank, the Trustee. An audit also includes
          assessing the accounting principles used and significant estimates
          made by the Trustee, 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 referred to
          above present fairly, in all material respects, the
          financial position of Defined Asset Funds - Municipal
          Investment Trust Fund, New York Series - A at October 31,
          1999 and the results of its operations and changes in its
          net assets for the above-stated periods in conformity with
          generally accepted accounting principles.

 DEFINED ASSET FUNDS - MUNICIPAL INVESTMENT TRUST FUND,
 NEW YORK SERIES - A

 NOTES TO PORTFOLIO
 As of October 31, 1999

(1)   The ratings of the Bonds are by Standard & Poor's Ratings Group, or by
      Moody's Investors Service, Inc. if followed by "(m)", or by Fitch
      Investors Service, Inc. if followed by "(f)"; "NR" indicates that this
      bond is not currently rated by any of the above-mentioned rating services.
      These ratings have been furnished by the Evaluator but not confirmed with
      rating agencies.

(2)   See Notes to Financial Statements.

(3)   Optional redemption provisions, which may be exercised in whole or in
      part, are initially at prices of par plus a premium, then subsequently at
      prices declining to par. Certain securities may provide for redemption at
      par prior or in addition to any optional or mandatory redemption dates or
      maturity, for example, through the operation of a maintenance and
      replacement fund, if proceeds are not able to be used as contemplated, the
      project is condemned or sold or the project is destroyed and insurance
      proceeds are used to redeem the securities. Many of the securities are
      also subject to mandatory sinking fund redemption commencing on dates
      which may be prior to the date on which securities may be optionally
      redeemed. Sinking fund redemptions are at par and redeem only part of the
      issue. Some of the securities have mandatory sinking funds which contain
      optional provisions permitting the issuer to increase the principal amount
      of securities called on a mandatory redemption date. The sinking fund
      redemptions with optional provisions may, and optional refunding
      redemptions generally will, occur at times when the redeemed securities
      have an offering side evaluation which represents a premium over par. To
      the extent that the securities were acquired at a price higher than the
      redemption price, this will represent a loss of capital when compared with
      the Public Offering Price of the Units when acquired. Distributions will
      generally be reduced by the amount of the income which would otherwise
      have been paid with respect to redeemed securities and there will be
      distributed to Holders any principal amount and premium received on such
      redemption after satisfying any redemption requests for Units received by
      the Fund. The estimated current return may be affected by redemptions.

(4)   Securities in the Portfolio have stated maturity dates ranging from 1999
      to 2020. The sellers are obligated to purchase the securities at the
      disposition dates indicated, which are earlier that the stated maturity
      dates. The Trustee is required under the Indenture to sell each of the
      securities on specific dates in the market if the price which can be
      obtained on any such date is in excess of par or, in all other cases, to
      the seller at par under the terms of the seller's repurchase commitment.
