FLORIDA INSURED PORTFOLIO--RISK/RETURN SUMMARY

1. WHAT IS THE FUND'S OBJECTIVE?
The Fund seeks interest income that is exempt from regular federal income
taxes and some state and local taxes by investing in a fixed portfolio
consisting primarily of insured, long term municipal revenue bonds.

2. WHAT ARE MUNICIPAL REVENUE BONDS?
Municipal 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 airports, health care
facilities, housing and municipal electric, water and sewer utilities.
Generally, payments on these bonds depend solely on the revenues generated by
the projects, 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 9 long-term tax-exempt municipal bonds
with an aggregate face amount of $3,055,000.

- The Fund is a unit investment trust which means that, unlike a mutual fund,
the Portfolio is not managed.

- The bonds are rated AAA or Aaa by Standard & Poor's, Moody's or Fitch.

- Many of the bonds can be called at a premium declining over time to par
value. Some bonds may be called earlier at par for extraordinary reasons.

- 100% of the bonds are insured by insurance companies that guarantee timely
payments of principal and interest on the bonds (but not Fund units or the
market value of the bonds before they mature).

The Portfolio consists of municipal bonds of the following types:

<TABLE>
<CAPTION>
APPROXIMATE
PORTFOLIO
PERCENTAGE
<S> <C>
/ /General Obligation 2%
/ /Hospitals/Health Care 26%
/ /Housing 2%
/ /Municipal Water/Sewer Utilities 31%
/ /Refunded Bonds 18%
/ /Stadium 21%
</TABLE>

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 drop in
bond ratings can reduce the price of your units.

- Because the Portfolio is concentrated in hospital/health care and municipal
water/ sewer utility bonds, adverse developments in these sectors 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.

- The Fund will receive early returns of principal 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.

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

3
<PAGE>
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 insured bonds of several different issuers.

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.

8. 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.

4
<PAGE>
9. 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.

<TABLE>
<S> <C>
UNIT PRICE PER UNIT $984.00
(as of July 31, 2000)
</TABLE>

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.

10. 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.

11. 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.
Your income may also be exempt from some Florida state and local taxes if you
live in Florida.

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.

12. 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, but the bonds will generally not be insured.
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 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.

<PAGE>
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.

<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

Many bonds can be prepaid or "called" by the issuer before their stated
maturity.

For example, some bonds may be required to be called pursuant to mandatory
sinking fund provisions.

Also, an issuer might call its bonds during periods of falling interest rates,
if the issuer's bonds have a coupon higher than current market rates.

An issuer might call its bonds in extraordinary cases, including if:

- it no longer needs the money for the original purpose;
- the project is condemned or sold;
- the project is destroyed and insurance proceeds are used to redeem the
bonds;
- any related credit support expires and is not replaced; or
- interest on the bonds become taxable.

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.

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.

Here is what you should know about New York and Florida Portfolios'
concentrations in hospital and health care bonds.

- payment for these bonds depends on revenues from private third-party payors
and government programs, including Medicare and Medicaid, which have
generally undertaken cost containment measures to limit payments to health
care providers;
- hospitals face increasing competition resulting from hospital mergers and
affiliations;
- hospitals need to reduce costs as HMOs increase market penetration and

11
<PAGE>
hospital supply and drug companies raise prices;
- hospitals and health care providers are subject to various legal claims by
patients and others and are adversely affected by increasing costs of
insurance; and
- many hospitals are aggressively buying physician practices and assuming risk
contracts to gain market share. If revenues do not increase accordingly,
this practice could reduce profits;
- Medicare is changing its reimbursement system for nursing homes. Many
nursing home providers are not sure how they will be treated. In many cases,
the providers may receive lower reimbursements and these would have to cut
expenses to maintain profitability; and
- most retirement/nursing home providers rely on entrance fees for operating
revenues. If people live longer than expected and turnover is lower than
budgeted, operating revenues would be adversely affected by less than
expected entrance fees.

Here is what you should know about Florida's concentration in municipal water
and sewer revenue bonds. The payment of interest and principal of these bonds
depends on the rates the utilities may charge, the demand for their services and
the cost of operating their business which includes the expense of complying
with environmental and other energy and licensing laws and regulations. The
operating results of utilities are particularly influenced by:

- increases in operating and construction costs; and
- unpredicability of future usage requirements.

Changes to the portfolio from bond redemptions, maturities and sales may affect
the Fund's concentrations over time.

STATE CONCENTRATION RISK

FLORIDA RISKS

GENERALLY

Florida's financial condition is affected by numerous national, economic, social
and environmental policies and conditions. For example:

- south Florida is heavily involved with foreign tourism, trade and investment
capital. As a result, the region is susceptible to international trade and
currency imbalances and economic problems in Central and South America;
- central and northern Florida are more vulnerable to agricultural problems,
such as crop failures or severe weather conditions, especially in the citrus
and sugar industries; and
- the state as a whole is also very dependent on tourism and construction.

STATE AND LOCAL GOVERNMENT

The state of Florida and its local governments are restricted in their ability
to raise taxes and incur debts. These restrictions limit their ability to
generate revenue, and so could hurt their ability to pay debts.

12
<PAGE>
General obligations of the state are rated Aa2 by Moody's, AA+ by Standard &
Poor's and AA by Fitch.

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-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
over $2 billion are projected for the 2002, 2003 and 2004 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 A2 by Moody's. $31.2 billion of combined City, MAC and PBC debt is
outstanding, and the City proposes $25.3 billion of financing over fiscal
1999-2003. New York City currently expects to reach its constitutional limits on
debt issuance in Fiscal 2003.

BOND QUALITY RISK

A reduction in a bond's rating may decrease its value and, indirectly, the value
of your investment in the Fund.

INSURANCE RELATED RISK

Some bonds are backed by insurance companies (as shown under Portfolios).
Insurance policies generally make payments only according to a bond's original
payment schedule and do not make early payments when a bond defaults or becomes
taxable. Although the federal government does not regulate the insurance
business, various state laws and federal initiatives and tax law changes could
significantly affect the insurance business. The claims-paying ability of the
insurance companies is generally rated A or better by Standard & Poor's or
another nationally recognized rating organization. The insurance company ratings

13
<PAGE>
are subject to change at any time at the discretion of the rating agencies.

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 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 28 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
14
<PAGE>
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.

If you acquire 25% or more of the outstanding units of the Fund and you sell
units with a value exceeding $250,000, the Trustee may choose to pay you "in
kind" by distributing bonds and cash with a total value equal to the price of
those units. The Trustee will try to distribute bonds in the portfolio pro rata,
but it reserves the right to distribute only one or a few bonds. The Trustee
will act as your agent in an in kind distribution and will either hold the bonds
for your account or sell them as you instruct. You must pay any transaction
costs as well as transfer and ongoing custodial fees on sales of bonds
distributed in kind.

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 at
a maximum exchange fee of 1.90%. 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. In addition, you may exchange into this Fund from certain other
Defined Asset Funds and unit trusts. 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.

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.

In addition, as with mutual funds, the Fund (and therefore the investors) pay
all or some of the costs of organizing the Fund including:

- cost of initial preparation of legal documents;
- federal and state registration fees;
- initial fees and expenses of the Trustee;
- initial audit; and

15
<PAGE>
- legal expenses and other out-of-pocket expenses.

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.

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,
typesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Portfolio's registration statement yearly are also
now chargeable to the Portfolio. While this fee may exceed the amount of these
costs and 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.

16
<PAGE>
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.

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

17
<PAGE>
- 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.

LEGAL OPINION

Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, as
counsel for the Sponsors, has given an opinion that the units are validly
issued. Special counsel located in the relevant states have given state and
local tax opinions.

AUDITORS

Deloitte & Touche LLP, 2 World Financial Center, New York, New York 10281,
independent accountants, audited the Statements of Condition included in this
prospectus.

SPONSORS

The Sponsors are:
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)

Each Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer each
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

The Fund and the Agent for the Sponsors have each adopted a code of ethics
requiring reporting of personal securities transactions by its employees with
access to information on Fund transactions. Subject to certain conditions, the
codes permit employees to invest in Fund securities for their own accounts. The
codes are designed to prevent fraud, deception and misconduct against the Fund
and to provide reasonable standards of conduct. These codes are on file with the
Commission and you may obtain a copy by contacting the Commission at the address
listed on the back cover of this prospectus.

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 bonds contained in the Portfolio. We cannot
predict whether any impact will be material to the Fund 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, financial institution,
insurance company or other investor with special circumstances or subject to
special rules. 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 of bond proceeds) 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.

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. Your gain, however,
will generally be ordinary income to the extent of any accrued "market
discount". Generally you will have market discount to the extent that your basis
in a bond when you purchase a unit is less than its stated redemption price at
maturity (or, if it is an original issue discount bond, the issue price
increased by original issue discount that has accrued on the bond before your
purchase). You should consult your tax adviser in this regard.

If your net long-term capital gains exceed your net short-term capital losses,
the excess may be subject to tax at a lower rate than ordinary income. Any
capital gain from the Fund will be long-term if you are considered to have held
your investment on each bond for more than one year and short-term

20
<PAGE>
otherwise. Because the deductibility of capital losses is subject to
limitations, you may not be able to deduct all of your capital losses.

YOUR BASIS IN THE BONDS

Your aggregate basis in the bonds will be equal to the cost of your units,
including any sales charges and the organizational expenses you pay, adjusted to
reflect any accruals of "original issue discount," "acquisition premium" and
"bond premium". You should consult your tax adviser in this regard.

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.

NEW YORK 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.

FLORIDA TAXES

In the opinion of Greenberg, Traurig, P.A., Miami, Florida, special counsel on
Florida tax matters:

Under the income tax laws of the State of Florida, the Florida Trust will not be
taxed as a corporation. Florida imposes an income tax on corporations but does
not impose a personal income tax. Accordingly, if you are an individual taxpayer
your income from the Trust will not be subject to tax in Florida. However, if
you are an entity that is normally taxed as a corporation, your income from the
fund will not be exempt from tax in Florida and special rules for taxation apply
depending on the type of entity. 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.

MUNICIPAL INVESTMENT TRUST FUND,
MULTISTATE SERIES - 315 (FLORIDA INSURED AND
NEW YORK TRUSTS),
DEFINED ASSET FUNDS

REPORT OF INDEPENDENT ACCOUNTANTS

The Sponsors, Trustee and Holders
of Municipal Investment Trust Fund,
Multistate Series - 315 (Florida Insured and
New York Trusts),
Defined Asset Funds:

We have audited the accompanying statements of condition of
Municipal Investment Trust Fund, Multistate Series - 315
(Florida Insured and New York Trusts), Defined Asset Funds,
including the portfolios, as of July 31, 2000 and the related
statements of operations and of changes in net assets for the
years ended July 31, 2000 and 1999 and the period August 11,
1997 to July 31, 1998. 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 auditing standards
generally accepted in the United States of America. 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 July 31,
2000, as shown in such portfolios, 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 Municipal Investment Trust Fund,
Multistate Series - 315 (Florida Insured and New York Trusts),
Defined Asset Funds at July 31, 2000 and the results of
their operations and changes in their net assets for the
above-stated periods in accordance with accounting principles
generally accepted in the United States of America.

NOTES TO PORTFOLIOS
As of July 31, 2000

(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 the 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) Insured by AAA-rated insurance companies that guarantee timely
payments of principal and interest on the bonds (but not Fund units
or the market value of the bonds before they mature).

(5) Insured by the indicated municipal bond insurance company.

(6) These bonds have been segregated to fund the deferred sales charges.

(7) Bonds with an aggregate face amount of $ 45,000 of the Florida
Insured Trust have been pre-refunded and are expected to be called
for redemption on the optional redemption provision date shown.
