INVESTMENT SUMMARY
ROTHSCHILD SMART BETA ERC STRATEGY, EUROZONE SERIES
---------------------------------------------------

INVESTMENT OBJECTIVE

The trust seeks to provide total return. There is no assurance the trust
will achieve its objective.

PRINCIPAL INVESTMENT STRATEGY

The trust seeks to achieve its objective by investing in a portfolio of
securities selected as of _________, 2016 (the "Eurozone Selection Date") using
the Rothschild Smart Beta ERC Eurozone Series UIT Strategy (the "Eurozone
Strategy") developed by Rothschild Asset Management Inc. and Risk Based
Investment Solutions Limited (collectively referred to herein as "Rothschild").

The Eurozone Strategy first identifies all securities meeting the following
criteria as of the Eurozone Selection Date:

* Security type of common stock according to Thomson Reuters via Markit
Group Ltd.;

* "Country Classification" of Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland or United Kingdom
according to Markit Group Ltd. (Country Classification is based on the
issuer's country of organization, headquarters, the primary listing of the
security and, in certain cases, additional indicators such as primary asset
and revenue location);

* Primary listing exchange of Vienna Stock Exchange, NYSE EURONEXT Brussels,
Prague Stock Exchange, NASDAQ OMX Copenhagen, NASDAQ OMX Helsinki, NYSE
EURONEXT Paris, Frankfurt Stock Exchange, Irish Stock Exchange, Borsa
Italiana, Luxembourg Stock Exchange, NYSE EURONEXT Amsterdam, Oslo Bors,
NYSE EURONEXT Lisbon, Bolsa De Madrid (including SIBE), Athens Stock
Exchange, NASDAQ OMX Stockholm, SIX Swiss Exchange or London Stock
Exchange;

* 3-month average daily traded volume greater than or equal to one (1)
million euros; and

* At least 253 days of closing prices.

From those securities, the Eurozone Strategy selects the securities with the
250 highest free-float market capitalizations (or all of the securities meeting
the above criteria if less than 250 securities met the above criteria as of the
Eurozone Selection Date). The free-float market capitalization of a security is
calculated by taking its free-float factor multiplied by its full market
capitalization (i.e. share price multiplied by number of outstanding shares)
based on the most recent closing price of a security. The free-float factor is
the proportion of the shares outstanding deemed to be available for purchase in
the public equity markets by international investors based on publicly available
shareholder information.

From those securities, the Eurozone Strategy eliminates securities that have
a U.S. dollar equivalent share price of greater than or equal to $5,000,
securities that are not denominated in euros and securities that have a primary
listing exchange of the Athens Stock Exchange.

From those securities, the Eurozone Strategy selects the securities with the
100 highest current market capitalizations (i.e. share price multiplied by
number of outstanding shares) or all of the securities meeting the above
criteria if less than 100 securities met the above criteria as of the Eurozone
Selection Date.

From those securities, the Eurozone Strategy selects the 50 securities that
have the lowest marginal "Risk Contributions" as defined using Rothschild's
proprietary rules-based formula (or all of the securities meeting the above
criteria if less than 50 securities met the above criteria as of the Eurozone
Selection Date). "Risk Contribution" is designed to calculate the amount of
risk that a particular security would contribute to a portfolio. Rothschild's
"Risk Contribution" formula uses factors including volatility of a security, a
security's correlation with other securities and a security's co-movement with
other securities.

The 50 (or fewer, if applicable) securities are weighted by the Eurozone
Strategy using Rothschild's proprietary rules-based "Equal Risk Contribution
Model" (referred to as the "ERC Model"). The ERC Model is designed to weight a
portfolio such that each security contributes equal risk to a portfolio based on
each security's Risk Contribution. However, as a result of potential
adjustments by the Eurozone Strategy as

2 Investment Summary

described below, securities in the trust portfolio could have different weighted
Risk Contributions as of the Eurozone Selection Date.

If the ERC Model results in one security comprising greater than 8% of the
portfolio, that security's weighting is dropped to 8% by the Eurozone Strategy
and the remaining securities are reweighted by the Eurozone Strategy using the
ERC Model. For example, if the ERC Model resulted in one security comprising
10% of the portfolio, the Eurozone Strategy would adjust the security's weight
down to 8% and use the ERC Model to re-weight the rest of the portfolio. If the
ERC Model results in the sum of securities individually comprising greater than
5% of the portfolio comprising greater than 40% of the portfolio, then the
security with the lowest weighting (which was still greater than 5%) is dropped
to 5% by the Eurozone Strategy and the remaining securities are reweighted by
the Eurozone Strategy using the ERC Model. If this does not reduce the sum of
exposures that were individually greater than 5% to less than or equal to 40%,
then the security with the next smallest weight (and still larger than 5%) is
dropped to 5% by the Eurozone Strategy and the remaining securities are
reweighted by the Eurozone Strategy using the ERC Model. This process continues
until the sum of securities individually comprising greater than 5% of the
portfolio comprise less than or equal to 40% of the portfolio. As a result of
these adjustments, securities in the portfolio could have different weighted
Risk Contributions as of the Eurozone Selection Date.

Please note that the Eurozone Strategy was applied to select the portfolio at
a particular time. If we<F1>* create additional units of the trust after the
trust's inception date, the trust will purchase the securities originally
selected by applying the Eurozone Strategy. This is true even if a later
application of the Eurozone Strategy would have resulted in the selection of
different securities.

Under normal circumstances, the trust will invest at least 80% of its assets
in Eurozone country securities. For this purpose, Eurozone country securities
include securities issued by issuers (1) organized in Eurozone countries, (2)
with headquarters or principal places of business located in Eurozone countries
or (3) doing a substantial amount of business in Eurozone countries (either 50%
or more of the issuer's assets are located in Eurozone countries or 50% or more
of the issuer's revenues are derived from Eurozone countries). For this
purpose, Eurozone countries include all European Union member countries that use
the euro as their official currency.

PRINCIPAL RISKS

As with all investments, you can lose money by investing in this trust. The
trust also might not perform as well as you expect. This can happen for reasons
such as these:

* SECURITY PRICES WILL FLUCTUATE. The value of your investment may fall over
time.

* AN ISSUER MAY BE UNWILLING OR UNABLE TO DECLARE DIVIDENDS IN THE FUTURE, OR
MAY REDUCE THE LEVEL OF DIVIDENDS DECLARED. This may result in a reduction
in the value of your units.

* THE FINANCIAL CONDITION OF AN ISSUER MAY WORSEN OR ITS CREDIT RATINGS MAY
DROP, RESULTING IN A REDUCTION IN THE VALUE OF YOUR UNITS. This may occur
at any point in time, including during the initial offering period.

* SECURITIES OF FOREIGN COMPANIES HELD BY THE TRUST PRESENT RISKS BEYOND THOSE
OF U.S. ISSUERS. These risks may include market and political factors
related to the company's foreign market, international trade conditions,
less regulation, smaller or less liquid markets, increased volatility,
differing accounting practices and changes in the value of foreign
currencies.

* THE TRUST IS CONSIDERED TO BE CONCENTRATED IN SECURITIES OF EUROPEAN
COMPANIES. Negative developments in Europe will affect the value of your
investment more than would be the case in a more diversified investment.

* THE TRUST'S PERFORMANCE MIGHT NOT SUFFICIENTLY CORRESPOND TO PUBLISHED
HYPOTHETICAL BACK-TESTED PERFORMANCE OF THE TRUST'S INVESTMENT STRATEGY.
This can happen for reasons such as an inability to exactly replicate the
weightings of securities in the strategy or be fully invested, timing of
the trust offering or timing of your investment, and trust expenses.
Hypothetical back-tested performance is not actual past performance of this
or any trust. Hypothetical back-tested performance is based on application
of a trust's investment strategy as of a particular time.

* WE DO NOT ACTIVELY MANAGE THE PORTFOLIO. Except in limited circumstances,
the trust will hold, and continue to buy, shares of the same securities
even if their market value declines.

EXAMPLE

This example helps you compare the cost of this trust with other unit trusts
and mutual funds. In the example we assume that the expenses do not change and
that the trust's annual return is 5%. Your actual returns and expenses will
vary. Based on these assumptions, you would pay these expenses for every
$10,000 you invest in the trust:

1 year $_____
3 years $_____
5 years $_____

Notes to Portfolio

(1) Securities are represented by contracts to purchase securities. The value
of each security is based on the evaluation of each security as of the
close of regular trading on the New York Stock Exchange on the business day
prior to the trust's inception date. Accounting Standards Codification
820, "Fair Value Measurements" establishes a framework for measuring fair
value and expands disclosure about fair value measurements in financial
statements for the trust. The framework under the standard is comprised of
a fair value hierarchy, which requires an entity to maximize the use of
observable inputs and minimize the use of unobservable inputs when
measuring fair value. The standard describes three levels of inputs that
may be used to measure fair value:

Level 1: Quoted prices (unadjusted) for identical assets or
liabilities in active markets that the trust has the ability to
access as of the measurement date.

Level 2: Significant observable inputs other than Level 1 prices,
such as quoted prices for similar assets or liabilities, quoted
prices in markets that are not active, and other inputs that are
observable or can be corroborated by observable market data.
Certain securities traded on non-U.S. exchanges may be valued using
indications of fair value provided by an independent pricing service
to reflect any significant market movements between the time the
trust values such securities and the earlier closing of such
non-U.S. markets. Such fair valuations are categorized as
Level 2 in the fair value hierarchy.

Level 3: Significant unobservable inputs that reflect the trust's own
assumptions about the assumptions that market participants would use
in pricing an asset or liability.

The inputs or methodologies used for valuing securities are not necessarily
an indication of the risk associated with investing those securities.

Changes in valuation techniques may result in transfers in or out of an
investment's assigned level as described above.

The following table summarizes the trust's investments as of the trust's
inception, based on inputs used to value them:

INVESTMENT SUMMARY
ROTHSCHILD SMART BETA ERC STRATEGY, JAPAN SERIES
------------------------------------------------

INVESTMENT OBJECTIVE

The trust seeks to provide total return. There is no assurance the trust
will achieve its objective.

PRINCIPAL INVESTMENT STRATEGY

The trust seeks to achieve its objective by investing in a portfolio of
securities selected as of _________, 2016 (the "Japan Selection Date") using the
Rothschild Smart Beta ERC Japan Series UIT Strategy (the "Japan Strategy")
developed by Rothschild Asset Management Inc. and Risk Based Investment
Solutions Limited (collectively referred to herein as "Rothschild").

The Japan Strategy first identifies all securities meeting the following
criteria as of the Japan Selection Date:

* Security type of common stock according to Thomson Reuters via
Markit Group Ltd.;

* Primary listing exchange of Tokyo Stock Exchange;

* 3-month average daily traded volume greater than or equal to
125 million yen; and

* At least 253 days of closing prices.

From those securities, the Japan Strategy selects the securities with the 400
highest free-float market capitalizations (or all of the securities meeting the
above criteria if less than 400 securities met the above criteria as of the
Japan Selection Date). The free-float market capitalization of a security is
calculated by taking its free-float factor multiplied by its full market
capitalization (i.e. share price multiplied by number of outstanding shares)
based on the most recent closing price of a security. The free-float factor is
the proportion of the shares outstanding deemed to be available for purchase in
the public equity markets by international investors based on publicly available
shareholder information.

From those securities, the Japan Strategy eliminates securities that have a
U.S. dollar equivalent share price of greater than or equal to $5,000.

From those securities, the Japan Strategy selects the 50 securities that have
the lowest marginal "Risk Contributions" as defined using Rothschild's
proprietary rules-based formula (or all of the securities meeting the above
criteria if less than 50 securities met the above criteria as of the Japan
Selection Date). "Risk Contribution" is designed to calculate the amount of
risk that a particular security would contribute to a portfolio. Rothschild's
"Risk Contribution" formula uses factors including volatility of a security, a
security's correlation with other securities and a security's co-movement with
other securities.

The 50 (or fewer, if applicable) securities are weighted by the Japan
Strategy using Rothschild's proprietary rules-based "Equal Risk Contribution
Model" (referred to as the "ERC Model"). The ERC Model is designed to weight a
portfolio such that each security contributes equal risk to a portfolio based on
each security's Risk Contribution. However, as a result of potential
adjustments by the Japan Strategy as described below, securities in the trust
portfolio could have different weighted Risk Contributions as of the Japan
Selection Date.

If the ERC Model results in one security comprising greater than 8% of the
portfolio, that security's weighting is dropped to 8% by the Japan Strategy and
the remaining securities are reweighted by the Japan Strategy using the ERC
Model. For example, if the ERC Model resulted in one security comprising 10% of
the portfolio, the Japan Strategy would adjust the security's weight down to 8%
and use the ERC Model to re-weight the rest of the portfolio. If the ERC Model
results in the sum of securities individually comprising greater than 5% of the
portfolio comprising greater than 40% of the portfolio, then the security with
the lowest weighting (which was still greater than 5%) is dropped to 5% by the
Japan Strategy and

Investment Summary 7

the remaining securities are reweighted by the Japan Strategy using the ERC
Model. If this does not reduce the sum of exposures that were individually
greater than 5% to less than or equal to 40%, then the security with the next
smallest weight (and still larger than 5%) is dropped to 5% by the Japan
Strategy and the remaining securities are reweighted by the Japan Strategy using
the ERC Model. This process continues until the sum of securities individually
comprising greater than 5% of the portfolio comprise less than or equal to 40%
of the portfolio. As a result of these adjustments, securities in the portfolio
could have different weighted Risk Contributions as of the Japan Selection Date.

Please note that the Japan Strategy was applied to select the portfolio at a
particular time. If we<F1>* create additional units of the trust after the
trust's inception date, the trust will purchase the securities originally
selected by applying the Japan Strategy. This is true even if a later
application of the Japan Strategy would have resulted in the selection of
different securities.

Under normal circumstances, the trust will invest at least 80% of its assets
in Japanese securities. For this purpose, Japanese securities include
securities issued by issuers (1) organized in Japan, (2) with headquarters or
principal places of business located in Japan or (3) doing a substantial amount
of business in Japan (either 50% or more of the issuer's assets are located in
Japan or 50% or more of the issuer's revenues are derived from Japan).

PRINCIPAL RISKS

As with all investments, you can lose money by investing in this trust. The
trust also might not perform as well as you expect. This can happen for reasons
such as these:

* SECURITY PRICES WILL FLUCTUATE. The value of your investment may fall over
time.

* AN ISSUER MAY BE UNWILLING OR UNABLE TO DECLARE DIVIDENDS IN THE FUTURE, OR
MAY REDUCE THE LEVEL OF DIVIDENDS DECLARED. This may result in a reduction
in the value of your units.

* THE TRUST IS CONSIDERED TO BE CONCENTRATED IN SECURITIES OF JAPANESE
COMPANIES. Negative developments in Japan will affect the value of your
investment more than would be the case in a more diversified investment.

* WE DO NOT ACTIVELY MANAGE THE PORTFOLIO. Except in limited circumstances,
the trust will hold, and continue to buy, shares of the same securities
even if their market value declines.

INVESTMENT SUMMARY
ROTHSCHILD SMART BETA ERC STRATEGY, U.S. SERIES
-----------------------------------------------

INVESTMENT OBJECTIVE

The trust seeks to provide total return. There is no assurance the trust
will achieve its objective.

PRINCIPAL INVESTMENT STRATEGY

The trust seeks to achieve its objective by investing in a portfolio of
securities selected as of _________, 2016 (the "U.S. Selection Date") using the
Rothschild Smart Beta ERC U.S. Series UIT Strategy (the "U.S. Strategy")
developed by Rothschild Asset Management Inc. and Risk Based Investment
Solutions Limited (collectively referred to herein as "Rothschild").

The U.S. Strategy first identifies all securities meeting the following
criteria as of the U.S. Selection Date:

* Security type of common stock according to Thomson Reuters via Markit
Group Ltd.;

* "Country Classification" of U.S. according to Markit Group Ltd. data
(Country Classification is based on the issuer's country of
organization, headquarters, the primary listing of the security and,
in certain cases, additional indicators such as primary asset and
revenue location);

* Primary listing exchange of NYSE and/or NASDAQ;

* 3-month average daily traded volume greater than or equal to one
(1) million U.S. dollars; and

* At least 253 days of closing prices.

From those securities, the U.S. Strategy selects the securities with the 500
highest free-float market capitalizations (or all of the securities meeting the
above criteria if less than 500 securities met the above criteria as of the U.S.
Selection Date). The free-float market capitalization of a security is
calculated by taking its free-float factor multiplied by its full market
capitalization (i.e. share price multiplied by number of outstanding shares)
based on the most recent closing price of a security. The free-float factor is
the proportion of the shares outstanding deemed to be available for purchase in
the public equity markets by international investors based on publicly available
shareholder information.

From those securities, the U.S. Strategy eliminates securities that have a
share price of greater than or equal to $5,000.

From those securities, the U.S. Strategy selects the securities with the 100
highest current market capitalizations (i.e. share price multiplied by number of
outstanding shares) or all of the securities meeting the above criteria if less
than 100 securities met the above criteria as of the U.S. Selection Date.

From those securities, the U.S. Strategy selects the 50 securities that had
the lowest marginal "Risk Contributions" as defined using Rothschild's
proprietary rules-based formula (or all of the securities meeting the above
criteria if less than 50 securities met the above criteria as of the U.S.
Selection Date). "Risk Contribution" is designed to calculate the amount of
risk that a particular security would contribute to a portfolio. Rothschild's
"Risk Contribution" formula uses factors including volatility of a security, a

each security's Risk Contribution. However, as a result of potential
adjustments by the U.S. Strategy as described below, securities in the trust
portfolio could have different weighted Risk Contributions as of the U.S.

12 Investment Summary

If the ERC Model results in one security comprising greater than 8% of the
portfolio, that security's weighting is dropped to 8% by the U.S. Strategy and
the remaining securities are reweighted by the U.S. Strategy using the ERC
Model. For example, if the ERC Model resulted in one security comprising 10% of
the portfolio, the U.S. Strategy would adjust the security's weight down to 8%

equal to 40% of the portfolio. As a result of these adjustments, securities in
the portfolio could have different weighted Risk Contributions as of the U.S.
Selection Date.

Please note that the U.S. Strategy was applied to select the portfolio at a
particular time. If we<F1>* create additional units of the trust after the
trust's inception date, the trust will purchase the securities originally
selected by applying the U.S. Strategy. This is true even if a later
application of the U.S. Strategy would have resulted in the selection of
different securities.

Under normal circumstances, the trust will invest at least 80% of its assets
in U.S. securities. For this purpose, U.S. securities include securities issued
by issuers (1) organized in the U.S., (2) with headquarters or principal places
of business located in the U.S. or (3) doing a substantial amount of business in
the U.S. (either 50% or more of the issuer's assets are located in the U.S. or
50% or more of the issuer's revenues are derived from the U.S.).

PRINCIPAL RISKS

As with all investments, you can lose money by investing in this trust. The
trust also might not perform as well as you expect. This can happen for reasons
such as these:

* SECURITY PRICES WILL FLUCTUATE. The value of your investment may fall over
time.

* AN ISSUER MAY BE UNWILLING OR UNABLE TO DECLARE DIVIDENDS IN THE FUTURE, OR
MAY REDUCE THE LEVEL OF DIVIDENDS DECLARED. This may result in a reduction
in the value of your units.

* THE FINANCIAL CONDITION OF AN ISSUER MAY WORSEN OR ITS CREDIT RATINGS MAY
DROP, RESULTING IN A REDUCTION IN THE VALUE OF YOUR UNITS. This may occur at
any point in time, including during the initial offering period.

* THE TRUST'S PERFORMANCE MIGHT NOT SUFFICIENTLY CORRESPOND TO PUBLISHED
HYPOTHETICAL BACK-TESTED PERFORMANCE OF THE TRUST'S INVESTMENT STRATEGY.
This can happen for reasons such as an inability to exactly replicate the
weightings of securities in the strategy or be fully invested, timing of the
trust offering or timing of your investment, and trust expenses.
Hypothetical back-tested performance is not actual past performance of this
or any trust. Hypothetical back-tested performance is based on application
of a trust's investment strategy as of a particular time.

* WE DO NOT ACTIVELY MANAGE THE PORTFOLIO. Except in limited circumstances,
the trust will hold, and continue to buy, shares of the same securities even
if their market value declines.

UNDERSTANDING YOUR INVESTMENT
-----------------------------

HOW TO BUY UNITS

You can buy units of a trust on any business day the New York Stock Exchange
is open by contacting your financial professional. Unit prices are available
daily on the Internet at WWW.AAMLIVE.COM. The public offering price of units
includes:

* the net asset value per unit plus

* organization costs plus

* the sales fee.

The "net asset value per unit" is the value of the securities, cash and other
assets in your trust reduced by the liabilities of your trust divided by the
total units or your trust outstanding. We often refer to the public offering
price of units as the price" or "purchase price." The offer price will be
effective for all orders received prior to the close of regular trading on the
New York Stock Exchange (normally 4:00 p.m. Eastern time). If we receive your
order prior to the close of regular trading on the New York Stock Exchange or
authorized financial professionals receive your order prior to that time and
properly transmit the order to us by the time that we designate, then you will
receive the price computed on the date of receipt. If we receive your order
after the close of regular trading on the New York Stock Exchange, if authorized
financial professionals receive your order after that time or if orders are
received by such persons and are not transmitted to us by the time that we
designate, then you will receive the price computed on the date of the next
determined offer price provided that your order is received in a timely manner
on that date. It is the responsibility of the authorized financial professional
to transmit the orders that they receive to us in a timely manner. Certain
broker-dealers may charge a transaction or other fee for processing unit
purchase orders.

VALUE OF THE SECURITIES. We determine the value of the securities as of the
close of regular trading on the New York Stock Exchange on each day that
exchange is open. We generally determine the value of securities using the last
sale price for securities traded on a national securities exchange. For this
purpose, the trustee provides us closing prices from a reporting service
approved by us. In some cases we will price a security based on its fair value
after considering appropriate factors relevant to the value of the security. We
will only do this if a security is not principally traded on a national
securities exchange or if the market quotes are unavailable or inappropriate.

We determined the initial prices of the securities shown under each
"Portfolio" section in this prospectus as described above at the close of
regular trading on the New York Stock Exchange on the business day before the
date of this prospectus. On the first day we sell units we will compute the
unit price as of the close of regular trading on the New York Stock Exchange or
the time the registration statement filed with the Securities and Exchange
Commission becomes effective, if later.

ORGANIZATION COSTS. During the initial offering period, part of the value of
the units represents an amount that will pay the costs of creating your trust.
These costs include the costs of preparing the registration statement and legal
documents, federal and state registration fees, the initial fees and expenses of
the trustee and the initial audit. Your trust will sell securities to reimburse
us for these costs at the end of the initial offering period or after six
months, if earlier. The value of your units will decline when your trust pays
these costs.

Understanding Your Investment 17

TRANSACTIONAL SALES FEE. You pay a fee in connection with purchasing units.
We refer to this fee as the "transactional sales fee." The transactional sales
fee has both an initial and a deferred component and equals 2.45% of the public
offering price per unit based on a $10 public offering price per unit. This
percentage amount of the transactional sales fee is based on the unit price on
your trust's inception date. The transactional sales fee equals the difference
between the total sales fee and the creation and development fee. As a result,
the percentage and dollar amount of the transactional sales fee will vary as the
public offering price per unit varies. The transactional sales fee does not
include the creation and development fee which is described under "Expenses."

The maximum sales fee equals 2.95% of the public offering price per unit at
the time of purchase. You pay the initial sales fee at the time you buy units.
The initial sales fee is the difference between the total sales fee percentage
(maximum of 2.95% of the public offering price per unit) and the sum of the
remaining fixed dollar deferred sales fee and the total fixed dollar creation
and development fee. The initial sales fee will be approximately 1.00% of the
public offering price per unit depending on the public offering price per unit.
The deferred sales fee is fixed at $0.145 per unit. Your trust pays the
deferred sales fee in equal monthly installments as described under "Investment
Summary--Fees and Expenses" for your trust. If you redeem or sell your units
prior to collection of the total deferred sales fee, you will pay any remaining
deferred sales fee upon redemption or sale of your units.

If you purchase units after the last deferred sales fee payment has been
assessed, the secondary market sales fee is equal to 2.95% of the public
offering price and does not include deferred payments (i.e. unitholders who buy
in the secondary market after collection of the deferred sales fee are not
charged deferred sales fees).

MINIMUM PURCHASE. The minimum amount you can purchase appears under
"Investment Summary--Essential Information" for your trust, but such amounts may
vary depending on your selling firm.

REDUCING YOUR SALES FEE. We offer a variety of ways for you to reduce the
fee you pay. It is your financial professional's responsibility to alert us of
any discount when you order units. Except as expressly provided herein, you may
not combine discounts. Since the deferred sales fee and the creation and
development fee are fixed dollar amounts per unit, your trust must charge these
fees per unit regardless of any discounts. However, if you are eligible to
receive a discount such that your total sales fee is less than the fixed dollar
amounts of the deferred sales fee and the creation and development fee, we will
credit you the difference between your total sales fee and these fixed dollar
fees at the time you buy units.

Large Purchases. You can reduce your sales fee by increasing the size of
your investment:

IF YOU PURCHASE: YOUR FEE WILL BE:
------------------------------------------

Less than $50,000 2.95%
$50,000 - $99,999 2.70
$100,000 - $249,999 2.45
$250,000 - $499,999 2.20
$500,000 - $999,999 1.95
$1,000,000 or more 1.40

We apply these fees as a percent of the public offering price per unit at the
time of purchase. The breakpoints will be adjusted to take into consideration
purchase orders stated in dollars which cannot be completely fulfilled due to
the requirements that only whole units be issued.

18 Understanding Your Investment

You aggregate initial offering period unit orders submitted by the same
person for units of any of the trusts we sponsor on any single day from any one
broker-dealer to qualify for a purchase level. If you purchase initial offering
period units that qualify for the fee account or rollover/exchange discount
described below and also purchase additional initial offering period units on a
single day from the same broker-dealer that do not qualify for the fee account
or rollover/exchange discount, you aggregate all initial offering period units
purchased for purposes of determining the applicable breakpoint level in the
table above on the additional units, but such additional units will not qualify
for the fee account or rollover/exchange discount described below. Secondary
market unit purchases are not aggregated with initial offering period unit
purchases for purposes of determining the applicable breakpoint level. You can
also include these orders as your own for purposes of this aggregation:

* orders submitted by your spouse or children (including step-children)
under 21 years of age living in the same household and

* orders submitted by your trust estate or fiduciary accounts.

The discounts described above apply only to initial offering period
purchases.

Fee Accounts. Investors may purchase units through registered investment
advisers, certified financial planners or registered broker-dealers who in each
case either charge investor accounts ("Fee Accounts") periodic fees for
brokerage services, financial planning, investment advisory or asset management
services, or provide such services in connection with an investment account for
which a comprehensive "wrap fee" charge ("Wrap Fee") is imposed. You should
consult your financial advisor to determine whether you can benefit from these
accounts. To purchase units in these Fee Accounts, your financial advisor must
purchase units designated with one of the Fee Account CUSIP numbers, if
available. Please contact your financial advisor for more information. If
units are purchased for a Fee Account and the units are subject to a Wrap Fee in
such Fee Account (i.e., the trust is "Wrap Fee Eligible") then investors may be
eligible to purchase units in these Fee Accounts that are not subject to the
transactional sales fee but will be subject to the creation and development fee
that is retained by the sponsor. For example, this table illustrates the sales
fee you will pay as a percentage of the initial $10 public offering price per
unit (the percentage will vary with the unit price).

Initial sales fee 0.00%
Deferred sales fee 0.00%
-------
Transactional sales fee 0.00%
=======
Creation and development fee 0.50%
-------
Total sales fee 0.50%
=======

This discount applies only during the initial offering period. Certain Fee
Account investors may be assessed transaction or other fees on the purchase
and/or redemption of units by their broker-dealer or other processing
organizations for providing certain transaction or account activities. We
reserve the right to limit or deny purchases of units in Fee Accounts by
investors or selling firms whose frequent trading activity is determined to be
detrimental to a trust.

Employees. We waive the transactional sales fee for purchases made by
officers, directors and employees (and immediate family members) of the sponsor
and its affiliates. These purchases are not subject to the transactional sales
fee but will be subject to the creation and development fee. We also waive a
portion of the sales fee for purchases

Understanding Your Investment 19

made by officers, directors and employees (and immediate family members) of
selling firms. These purchases are made at the public offering price per unit
less the applicable regular dealer concession. Immediate family members for the
purposes of this section include your spouse, children (including step-children)
under the age of 21 living in the same household, and parents (including step-
parents). These discounts apply to initial offering period and secondary market
purchases. All employee discounts are subject to the policies of the related
selling firm, including but not limited to, householding policies or
limitations. Only officers, directors and employees (and their immediate family
members) of selling firms that allow such persons to participate in this
employee discount program are eligible for the discount.

Rollover/Exchange Option. We waive a portion of the sales fee on units of
the trusts offered in this prospectus if you buy your units with redemption or
termination proceeds from any unit investment trust (regardless of sponsor).
The discounted public offering price per unit for these transactions is equal to
the regular public offering price per unit less 1.00%. However, if you invest
redemption or termination proceeds of $500,000 or more in units, the maximum
sales fee on your units will be limited to the maximum sales fee for the
applicable amount invested in the table under "Large Purchases" above. To
qualify for this discount, the termination or redemption proceeds used to
purchase units of a trust offered in this prospectus must be derived from a
transaction that occurred within 30 calendar days of your purchase of units of a
trust offered in this prospectus. In addition, the discount will only be
available for investors that utilize the same broker-dealer (or a different
broker-dealer with appropriate notification) for both the unit purchase and the
transaction resulting in the receipt of the termination or redemption proceeds
used for the unit purchase. You may be required to provide appropriate
documentation or other information to your broker-dealer to evidence your
eligibility for this sales fee discount.

Please note that if you purchase units of a trust in this manner using
redemption proceeds from trusts which assess the amount of any remaining
deferred sales fee at redemption, you should be aware that any deferred sales
fee remaining on these units will be deducted from those redemption proceeds.
These discounts apply only to initial offering period purchases.

Dividend Reinvestment Plan. We do not charge any sales fee when you reinvest
distributions from your trust into additional units of your trust. This sales
fee discount applies to initial offering period and secondary market purchases.
Since the deferred sales fee and the creation and development fee are fixed
dollar amounts per unit, your trust must charge these fees per unit regardless
of this discount. If you elect the distribution reinvestment plan, we will
credit you with additional units with a dollar value sufficient to cover the
amount of any remaining deferred sales fee or creation and development fee that
will be collected on such units at the time of reinvestment. The dollar value
of these units will fluctuate over time.

RETIREMENT ACCOUNTS. Your portfolio may be suitable for purchase in tax-
advantaged retirement accounts. You should contact your financial professional
about the accounts offered and any additional fees imposed.

HOW TO SELL YOUR UNITS

You can sell or redeem your units on any business day the New York Stock
Exchange is open by contacting your financial professional. Unit prices are
available daily on the Internet at

20 Understanding Your Investment

WWW.AAMLIVE.COM or through your financial professional. The sale and redemption
price of units is equal to the net asset value per unit, provided that you will
not pay any remaining creation and development fee or organization costs if you
sell or redeem units during the initial offering period. The sale and
redemption price is sometimes referred to as the "liquidation price." You pay
any remaining deferred sales fee when you sell or redeem your units. Certain
broker-dealers may charge a transaction or other fee for processing unit
redemption or sale requests.

SELLING UNITS. We may maintain a secondary market for units. This means
that if you want to sell your units, we may buy them at the current net asset
value, provided that you will not pay any remaining creation and development fee
or organization costs if you sell units during the initial offering period. We
may then resell the units to other investors at the public offering price or
redeem them for the redemption price. Our secondary market repurchase price is
the same as the redemption price. Certain broker-dealers might also maintain a
secondary market in units. You should contact your financial professional for
current repurchase prices to determine the best price available. We may
discontinue our secondary market at any time without notice. Even if we do not
make a market, you will be able to redeem your units with the trustee on any
business day for the current redemption price.

REDEEMING UNITS. You may also redeem your units directly with the trustee,
The Bank of New York Mellon, on any day the New York Stock Exchange is open.
The redemption price that you will receive for units is equal to the net asset
value per unit, provided that you will not pay any remaining creation and
development fee or organization costs if you redeem units during the initial
offering period. You will pay any remaining deferred sales fee at the time you
redeem units. You will receive the net asset value for a particular day if the
trustee receives your completed redemption request prior to the close of regular
trading on the New York Stock Exchange. Redemption requests received by
authorized financial professionals prior to the close of regular trading on the
New York Stock Exchange that are properly transmitted to the trustee by the time
designated by the trustee, are priced based on the date of receipt. Redemption
requests received by the trustee after the close of regular trading on the New
York Stock Exchange, redemption requests received by authorized financial
professionals after that time or redemption requests received by such persons
that are not transmitted to the trustee until after the time designated by the
trustee, are priced based on the date of the next determined redemption price
provided they are received in a timely manner by the trustee on such date. It
is the responsibility of authorized financial professionals to transmit
redemption requests received by them to the trustee so they will be received in
a timely manner. If your request is not received in a timely manner or is
incomplete in any way, you will receive the next net asset value computed after
the trustee receives your completed request.

If you redeem your units, the trustee will generally send you a payment for
your units no later than seven days after it receives all necessary
documentation (this will usually only take three business days). The only time
the trustee can delay your payment is if the New York Stock Exchange is closed
(other than weekends or holidays), the Securities and Exchange Commission
determines that trading on that exchange is restricted or an emergency exists
making sale or evaluation of the securities not reasonably practicable, and for
any other period that the Securities and Exchange Commission permits.

Understanding Your Investment 21

You can request an in-kind distribution of the securities underlying your
units if you tender at least 2,500 units for redemption (or such other amount as
required by your financial professional's firm). This option is generally
available only for securities traded and held in the United States. The trustee
will make any in-kind distribution of securities by distributing applicable
securities in book entry form to the account of your financial professional at
Depository Trust Company. You will receive whole shares of the applicable
securities and cash equal to any fractional shares. You may not request this
option in the last 30 days of your trust's life. We may discontinue this option
upon sixty days notice.

EXCHANGE OPTION. You may be able to exchange your units for units of our
unit trusts at a reduced sales fee. You can contact your financial professional
for more information about trusts currently available for exchanges. Before you
exchange units, you should read the prospectus carefully and understand the
risks and fees. You should then discuss this option with your financial
professional to determine whether your investment goals have changed, whether
current trusts suit you and to discuss tax consequences. We may discontinue
this option at any time upon sixty days notice.

ROLLOVER OPTION. Your trust's strategy is a long-term investment strategy
designed to be followed on an annual basis. You may achieve more consistent
long-term investment results by following the strategy. As part of the
strategy, we currently intend to offer a subsequent series of your trust for a
rollover when the current trust terminates. When your trust terminates you will
have the option to (1) participate in a rollover and have your units reinvested
into a subsequent trust series through a cash rollover as described in this
section, (2) receive an in-kind distribution of securities or (3) receive a cash
distribution.

If you elect to participate in a rollover, your units will be redeemed on
your trust's termination date. As the redemption proceeds become available, the
proceeds (including dividends) will be invested in a new trust series, if
available, at the public offering price for the new trust. The trustee will
attempt to sell securities to satisfy the redemption as quickly as practicable
on the termination date. We do not anticipate that the sale period will be
longer than one day, however, certain factors could affect the ability to sell
the securities and could impact the length of the sale period. The liquidity of
any security depends on the daily trading volume of the security and the amount
available for redemption and reinvestment on any day.

We intend to make subsequent trust series available for sale at various times
during the year. Of course, we cannot guarantee that a subsequent trust or
sufficient units will be available or that any subsequent trusts will offer the
same investment strategies or objectives as your current trust. We cannot
guarantee that a rollover will avoid any negative market price consequences
resulting from trading large volumes of securities. Market price trends may
make it advantageous to sell or buy securities more quickly or more slowly than
permitted by the trust procedures. We may, in our sole discretion, modify a
rollover or stop creating units of a trust at any time regardless of whether all
proceeds of unitholders have been reinvested in a rollover. We may decide not
to offer the rollover option upon sixty days notice. Cash which has not been
reinvested in a rollover will be distributed to unitholders shortly after the
termination date. Rollover participants may receive taxable dividends or
realize taxable capital gains which are reinvested in connection with a rollover
but may

22 Understanding Your Investment

not be entitled to a deduction for capital losses due to the "wash sale" tax
rules. Due to the reinvestment in a subsequent trust, no cash will be
distributed to pay any taxes. See "Taxes".

DISTRIBUTIONS

MONTHLY DISTRIBUTIONS. Your trust generally pays distributions of its net
investment income (pro-rated on an annual basis) along with any excess capital
on each monthly distribution date to unitholders of record on the preceding
record date. The record and distribution dates are shown under "Essential
Information" in the "Investment Summary" section of this prospectus. In some
cases, your trust might pay a special distribution if it holds an excessive
amount of cash pending distribution. For example, this could happen as a result
of a merger or similar transaction involving a company whose stock is in your
portfolio. Your trust will also generally make required distributions or
distributions to avoid imposition of tax at the end of each year because it is
structured as a "regulated investment company" for federal tax purposes. The
amount of your distributions will vary from time to time as companies change
their dividends or trust expenses change.

When your trust receives dividends from a portfolio security, the trustee
credits the dividends to the trust's accounts. In an effort to make relatively
regular income distributions, your trust's monthly income distribution is equal
to one-twelfth of the estimated net annual dividends to be received by your
trust after deduction of trust operating expenses. Because your trust does not
receive dividends from the portfolio securities at a constant rate throughout
the year, your trust's income distributions to unitholders may be more or less
than the amount credited to your trust accounts as of the record date. For the
purpose of minimizing fluctuation in income distributions, the trustee is
authorized to advance such amounts as may be necessary to provide income
distributions of approximately equal amounts. The trustee will be reimbursed,
without interest, for any such advances from available income received by your
trust on the ensuing record date.

ESTIMATED ANNUAL DISTRIBUTIONS. The estimated net annual distributions for
your trust is shown under "Essential Information" in the "Investment Summary"
section of this prospectus related to your trust. We generally base the
estimate of the income your trust may receive on annualizing the most recent
ordinary dividend declared by an issuer (or adding the most recent interim and
final dividends declared for certain foreign issuers) or on scheduled income
payments. However, dividend conventions for certain companies and/or certain
countries differ from those typically used in the United States and in certain
instances, dividends paid or declared over several years or other periods were
used to estimate annual distributions. Due to this and various other factors,
actual dividends received by your trust will most likely differ from the most
recent annualized dividends or scheduled income payments. The actual net annual
distributions you will receive will vary with changes in your trust's fees and
expenses, in dividends received and with the sale of securities.

REPORTS. The trustee or your financial professional will make available to
you a statement showing income and other receipts of your trust for each
distribution. Each year the trustee will also provide an annual report on your
trust's activity and certain tax information. You can request copies of
security evaluations to enable you to complete your tax forms and audited
financial statements for your trust, if available.

Understanding Your Investment 23

INVESTMENT RISKS

All investments involve risk. This section describes the main risks that can
impact the value of the securities in your portfolio. You should understand
these risks before you invest. If the value of the securities falls, the value
of your units will also fall. We cannot guarantee that your trust will achieve
its objective or that your investment return will be positive over any period.

MARKET RISK is the risk that the value of the securities in your trust will
fluctuate. This could cause the value of your units to fall below your original
purchase price. Market value fluctuates in response to various factors. These
can include changes in interest rates, inflation, the financial condition of a
security's issuer, perceptions of the issuer, or ratings on a security. Even
though we supervise your portfolio, you should remember that we do not manage
your portfolio. Your trust will not sell a security solely because the market
value falls as is possible in a managed fund.

DIVIDEND PAYMENT RISK is the risk that an issuer of a security is unwilling
or unable to pay income on a security. Stocks represent ownership interests in
the issuers and are not obligations of the issuers. Common stockholders have a
right to receive dividends only after the company has provided for payment of
its creditors, bondholders and preferred stockholders. Common stocks do not
assure dividend payments. Dividends are paid only when declared by an issuer's
board of directors and the amount of any dividend may vary over time.

STRATEGY CORRELATION RISK is the risk that your trust's performance will not
sufficiently correspond with the hypothetical back-tested performance of the
trust's investment strategy. This can happen for reasons such as:

* the impracticability of owning each of the strategy stocks with the exact
weightings at a given time,

* strategy performance is based on a calendar year strategy while trusts may
be created at various times during the year and generally have 15 month
terms,

* your trust may not be fully invested at all times, and

* trust fees and expenses.

Hypothetical back-tested performance is not actual past performance of this
or any trust. Hypothetical back-tested performance is based on application of a
trust's investment strategy as of a particular time.

FOREIGN ISSUER RISK. The Rothschild Smart Beta ERC Strategy, Eurozone Series
and Rothschild Smart Beta ERC Strategy, Japan Series trusts invest in securities
issued by foreign issuers. An investment in securities of foreign issuers
involves certain risks that are different in some respects from an investment in
securities of domestic issuers. These include risks associated with future
political and economic developments, international trade conditions, foreign
withholding taxes, liquidity concerns, currency fluctuations, volatility,
restrictions on foreign investments and exchange of securities, potential for
expropriation of assets, confiscatory taxation, difficulty in obtaining or
enforcing a court judgment, potential inability to collect when a company goes
bankrupt and economic, political or social instability. Moreover, individual
foreign economies may differ favorably or unfavorably from the U.S. economy for
reasons including differences in growth of gross domestic product, rates of
inflation, capital

24 Understanding Your Investment

reinvestment, resources, self-sufficiency and balance of payments positions.
There may be less publicly available information about a foreign issuer than is
available from a domestic issuer as a result of different accounting, auditing
and financial reporting standards. Some foreign markets are less liquid than
U.S. markets which could cause securities to be bought at a higher price or sold
at a lower price than would be the case in a highly liquid market.

Securities of certain foreign issuers may be denominated or quoted in
currencies other than the U.S. dollar. Foreign issuers also make payments and
conduct business in foreign currencies. Many foreign currencies have fluctuated
widely in value against the U.S. dollar for various economic and political
reasons. Changes in foreign currency exchange rates may affect the value of
foreign securities and income payments. Generally, when the U.S. dollar rises
in value against a foreign currency, a security denominated in that currency
loses value because the currency is worth fewer U.S. dollars. Conversely, when
the U.S. dollar decreases in value against a foreign currency, a security
denominated in that currency gains value because the currency is worth more U.S.
dollars. The U.S. dollar value of income payments on foreign securities will
fluctuate similarly with changes in foreign currency values.

Brokerage and other transaction costs on foreign exchanges are often higher
than in the U.S. and there is generally less governmental supervision of
exchanges, brokers and issuers in foreign countries. The increased expense of
investing in foreign markets may reduce the amount an investor can earn on its
investments and typically results in a higher operating expense ratio than
investments in only domestic securities. Custody of certain securities may be
maintained by a global custody and clearing institution. Settlement and
clearance procedures in certain foreign markets differ significantly from those
in the U.S. Foreign settlement and clearance procedures and trade regulations
also may involve certain risks (such as delays in payment for or delivery of
securities) not typically associated with the settlement of domestic securities.
Round lot trading requirements exist in certain foreign securities markets which
could cause the proportional composition and diversification of the portfolio to
vary when the trust buys or sells securities.

Certain foreign securities may be held in the form of American Depositary
Receipts ("ADRs"), Global Depositary Receipts ("GDRs"), or other similar
receipts. Depositary receipts represent receipts for foreign securities
deposited with a custodian (which may include the trustee of the trust).
Depository receipts may not be denominated in the same currency as the
securities into which they may be converted. ADRs typically trade in the U.S.
in U.S. dollars and are registered with the Securities and Exchange Commission.
GDRs are similar to ADRs, but GDRs typically trade outside of the U.S. and
outside of the country of the issuer in the currency of the country where the
GDR trades. Depositary receipts generally involve most of the same types of
risks as foreign securities held directly but typically also involve additional
expenses associated with the cost of the custodian's services. Some depositary
receipts may experience less liquidity than the underlying securities traded in
their home market. Certain depositary receipts are unsponsored (i.e. issued
without the participation or involvement of the issuer of the underlying
security). The issuers of unsponsored depositary receipts are not obligated to
disclose information that may be considered material in the U.S. Therefore,
there may be less information available regarding these issuers which can impact
the relationship between certain information impacting a security and the market
value of the depositary receipts.

EUROPEAN ISSUER RISKS. The Rothschild Smart Beta ERC Strategy, Eurozone
Series trust invests in securities issued by companies in Europe. The trust is
therefore subject to certain risks associated specifically with Europe. A
significant number of countries in Europe are member states in the European
Union, and the member states no longer control their own monetary policies by
directing independent interest rates for their currencies. In these member
states, the authority to direct monetary policies including money supply and
official interest rates for the Euro is exercised by the European Central Bank.
Furthermore, the European sovereign debt crisis and the related austerity
measures in certain countries have had, and continue to have, a significant
impact on the economies of certain European countries and their future economic
outlooks.

JAPANESE ISSUER RISK. The Rothschild Smart Beta ERC Strategy, Japan Series
trust invests in securities issued by companies in Japan. At times, the growth
of Japan's economy has lagged that of many of its Asian neighbors and other
major developed economies. The Japanese economy is heavily dependent on
international trade and has sometimes been adversely affected by trade tariffs,
other protectionist measures, competition from emerging economies and the
economic conditions of its trading partners. China has become an important
trading partner with Japan, yet the countries' political relationship has often
been strained. Should political tension increase, it could adversely affect the
economy, especially the export sector, and destabilize the region as a whole.
Japan also remains heavily dependent on oil imports and higher commodity prices
could have a negative impact on the economy. The Japanese economy faces several
other concerns, including a financial system with large levels of nonperforming
loans, over-leveraged corporate balance sheets, extensive cross-ownership by
major corporations, a changing corporate governance structure, and large
government deficits. These issues may cause a slowdown of the Japanese economy.
The Japanese yen has fluctuated widely at times and any increase in its value
may cause a decline in exports that could weaken the Japanese economy. Japan
has, in the past, intervened in the currency markets to attempt to maintain or
reduce the value of the yen. Japanese intervention in the currency markets
could cause the value of the yen to fluctuate sharply and unpredictably and
could cause losses to investors.

LEGISLATION OR LITIGATION RISK is the risk that various legislative
initiatives will be proposed from time to time in the United States and abroad
which may have a negative impact on certain of the companies represented in your
trust. In addition, litigation regarding any of the issuers of the securities
or of the industries represented by these issuers may negatively impact the
share prices of these securities. No one can predict what impact any pending or
threatened litigation will have on the share prices of the securities.

LIQUIDITY RISK is the risk that the value of a security will fall if trading
in the security is limited or absent. No one can guarantee that a liquid
trading market will exist for any security.

NO FDIC GUARANTEE. An investment in a trust is not a deposit of any bank and
is not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency.

HYPOTHETICAL BACK-TESTED PERFORMANCE INFORMATION

The following table compares hypothetical back-tested performance information
for the strategy employed by each trust and the actual performance of various
indexes in each of the years listed below (and as of the most recent month).
These hypothetical back-tested returns do not guarantee and should not be used
to predict future performance of any trust. Returns from your

26 Understanding Your Investment

trust will differ from the hypothetical strategy returns for several
reasons, including:

* total return figures shown do not reflect commissions paid by your trust on
the purchase of securities or taxes you will incur;

* strategy returns are for calendar years (and through the most recent
month), while trusts begin and end on various dates;

* extraordinary market events that are not expected to be repeated and may
have affected performance;

* your trust has a scheduled term longer than one year;

* your trust may not be fully invested at all times or match the strategy
weightings in all securities comprising its strategy; and

* your trust often purchases or sells securities at prices different from the
closing prices used in buying and selling units.

You should note that the trusts are not designed to parallel movements in any
index, and it is not expected that they will do so. In fact, each trust's
strategy underperformed its comparative index in certain years and we cannot
guarantee that any trust will outperform its related index over the life of the
trust or over consecutive rollover periods, if available.

Hypothetical back-tested performance is no guarantee of future results.
Hypothetical back-tested performance of each trust's strategy's stocks (the
"strategy securities") is hypothetical (does not represent any actual trust), is
shown for illustrative purposes only and is not intended to indicate the future
performance of any investment, including your trust. The strategy securities
for a given year consist of the securities selected by applying the strategy on
the last business day of each year (and not the date a trust actually sells
units). Total return represents the sum of the change in market value of each
group of securities between the first and last trading day of a period plus the
total dividends paid on each group of stocks during such period divided by the
opening market value of each group of securities as of the first trading day of
a period.

Securities are selected through application of each strategy at a particular
point in time and if a security which is a component of a strategy is merged out
of existence, de-listed or suffers a similar fate during the period in which the
strategy performance is being measured, such security will not be replaced by
another security during that period. The strategies are not rebalanced during
each one year period and as a result the securities used for determining
hypothetical back-tested performance will not take into account subsequent
changes to the starting points for the strategies.

Total return figures shown above in the table assume that all dividends are
reinvested as of their distribution date. Strategy figures reflect the
deduction of sales charges and expenses but have not been reduced by estimated
brokerage commissions and other transaction costs paid by a trust in acquiring
securities or any taxes incurred by investors.

Hypothetical back-tested returns are hypothetical, meaning that they do not
represent actual trading, and, thus, may not reflect material economic and
market factors, such as liquidity constraints, that may have had an impact on
actual decision making. The hypothetical back-tested performance is the
retroactive application of the strategy designed with the full benefit of
hindsight.

The S&P 100(R) Index is designed to measure the performance of the large-

HOW THE TRUST WORKS

YOUR TRUST. Your trust is a unit investment trust registered under the
Investment Company Act of 1940. We created your trust under a trust agreement
between Advisors Asset Management, Inc. (as

28 Understanding Your Investment

depositor/sponsor, evaluator and supervisor) and The Bank of New York Mellon (as
trustee). To create your trust, we deposited securities with the trustee (or
contracts to purchase securities along with an irrevocable letter of credit or
other consideration to pay for the securities). In exchange, the trustee
delivered units of your trust to us. Each unit represents an undivided interest
in the assets of your trust. These units remain outstanding until redeemed or
until your trust terminates. At the close of the New York Stock Exchange on
your trust's inception date, the number of units may be adjusted so that the
public offering price per unit equals $10. The number of units and fractional
interest of each unit in your trust will increase or decrease to the extent of
any adjustment.

CHANGING YOUR PORTFOLIO. Your trust is not a managed fund. Unlike a managed
fund, we designed your portfolio to remain relatively fixed. Your trust will
generally buy and sell securities:

* to pay expenses,

* to issue additional units or redeem units,

* in limited circumstances to protect your trust,

* to make required distributions or avoid imposition of taxes on your trust,
or

* as permitted by the trust agreement.

When your trust sells securities, the composition and diversification of the
securities in the portfolio may be altered. If a public tender offer has been
made for a security or a merger, acquisition or similar transaction has been
announced affecting a security, the trustee may either sell the security or
accept a tender offer if the supervisor determines that the action is in the
best interest of unitholders. The trustee will distribute any cash proceeds to
unitholders. If an offer by the issuer of any of the portfolio securities or
any other party is made to issue new securities, or to exchange securities, for
trust portfolio securities, the trustee will at the direction of the sponsor,
vote for or against, or accept or reject, any offer for new or exchanged
securities or property in exchange for a trust portfolio security. If any such
issuance, exchange or substitution occurs (regardless of any action or rejection
by a trust), any securities and/or property received will be deposited into your
trust and will be promptly sold by the trustee pursuant to the sponsor's
direction, unless the sponsor advises the trustee to keep such securities or
property. If any contract for the purchase of securities fails, the sponsor
will refund the cash and sales fee attributable to the failed contract to
unitholders on or before the next distribution date unless substantially all of
the moneys held to cover the purchase are reinvested in substitute securities in
accordance with the trust agreement. The sponsor may direct the reinvestment of
security sale proceeds if the sale is the direct result of serious adverse
credit factors which, in the opinion of the sponsor, would make retention of the
securities detrimental to your trust. In such a case, the sponsor may, but is
not obligated to, direct the reinvestment of sale proceeds in any other
securities that meet the criteria for inclusion in your trust on your trust's
inception date. The sponsor may also instruct the trustee to take action
necessary to ensure that the portfolio continues to satisfy the qualifications
of a regulated investment company.

We will increase the size of your trust as we sell units. When we create
additional units, we will seek to replicate the existing portfolio. When your
trust buys securities, it may pay brokerage or other acquisition fees. You
could experience a dilution of your investment because of these fees and
fluctuations in security prices between the time we create units and the time
your trust buys the securities. When your trust buys or sells securities, we
may direct that it place orders with and pay brokerage

Understanding Your Investment 29

commissions to brokers that sell units or are affiliated with us, your trust or
the trustee.

Pursuant to an exemptive order, your trust may be able to purchase securities
from other trusts that we sponsor when we create additional units. Your trust
may also be able to sell securities to other trusts that we sponsor to satisfy
unit redemption, pay deferred sales charges or expenses, in connection with
periodic tax compliance or in connection with the termination of your trust.
The exemption may enable each trust to eliminate commission costs on these
transactions. The price for those securities will be the closing price on the
sale date on the exchange where the securities are principally traded as
certified by us to the trustee.

AMENDING THE TRUST AGREEMENT. The sponsor and the trustee can change the
trust agreement without your consent to correct any provision that may be
defective or to make other provisions that will not materially adversely affect
your interest (as determined by the sponsor and the trustee). We cannot change
this agreement to reduce your interest in your trust without your consent.
Investors owning two-thirds of the units in your trust may vote to change this
agreement.

TERMINATION OF YOUR TRUST. Your trust will terminate on the termination date
set forth under "Essential Information" in the "Investment Summary" section of
this prospectus for your trust. The trustee may terminate your trust early if
the value of the trust is less than 40% of the original value of the securities
in your trust at the time of deposit. At this size, the expenses of your trust
may create an undue burden on your investment. Investors owning two-thirds of
the units in your trust may also vote to terminate the trust early. The trustee
will liquidate your trust in the event that a sufficient number of units not yet
sold to the public are tendered for redemption so that the net worth of your
trust would be reduced to less than 40% of the value of the securities at the
time they were deposited in the trust. If this happens, we will refund any
sales charge that you paid.

The trustee will notify you of any termination and sell any remaining
securities. The trustee will send your final distribution to you within a
reasonable time following liquidation of all the securities after deducting
final expenses. Your termination distribution may be less than the price you
originally paid for your units.

THE SPONSOR. The sponsor of your trust is Advisors Asset Management, Inc.
We are a broker-dealer specializing in providing trading and support services to
broker-dealers, registered representatives, investment advisers and other
financial professionals. Our headquarters are located at 18925 Base Camp Road,
Monument, Colorado 80132. You can contact our unit investment trust division at
8100 East 22nd Street North, Building 800, Suite 102, Wichita, Kansas 67226 or

registered broker-dealer and investment adviser, a member of the Financial
Industry Regulatory Authority, Inc. (FINRA) and Securities Investor Protection
Corporation (SIPC) and a registrant of the Municipal Securities Rulemaking Board
(MSRB). If we fail to or cannot perform our duties as sponsor or become
bankrupt, the trustee may replace us, continue to operate your trust without a
sponsor, or terminate your trust.

We and your trust have adopted a code of ethics requiring our employees who
have access to information on trust transactions to report personal securities
transactions. The purpose of the code is to avoid potential conflicts of
interest and to prevent fraud, deception or misconduct with respect to your
trust.

30 Understanding Your Investment

The sponsor or an affiliate may use the list of securities in your trust in
its independent capacity (which may include acting as an investment adviser or
broker-dealer) and distribute this information to various individuals and
entities. The sponsor or an affiliate may recommend or effect transactions in
the securities. This may also have an impact on the price your trust pays for
the securities and the price received upon unit redemption or trust termination.
The sponsor may act as agent or principal in connection with the purchase and
sale of securities, including those held by your trust, and may act as a
specialist market maker in the securities. The sponsor may also issue reports
and make recommendations on the securities in your trust. The sponsor or an
affiliate may have participated in a public offering of one or more of the
securities in your trust. The sponsor, an affiliate or their employees may have
a long or short position in these securities or related securities. An officer,
director or employee of the sponsor or an affiliate may be an officer or
director for the issuers of the securities.

THE TRUSTEE. The Bank of New York Mellon is the trustee of your trust with
its principal unit investment trust division offices located at 2 Hanson Place,
12th Floor, Brooklyn, New York 11217. You can contact the trustee by calling
the telephone number on the back cover of this prospectus or by writing to its
unit investment trust office. We may remove and replace the trustee in some
cases without your consent. The trustee may also resign by notifying us and
investors.

HOW WE DISTRIBUTE UNITS. We sell units to the public through broker-dealers
and other firms. We pay part of the sales fee to these distribution

Understanding Your Investment 31

firms when they sell units. During the initial offering period, the
distribution fee (the broker-dealer concession or agency commission) for broker-
dealers and other firms is as follows:

TRANSACTION CONCESSION OR
AMOUNT: AGENCY COMMISSION:
------------------------------------------

Less than $50,000 2.25%
$50,000 - $99,999 2.00
$100,000 - $249,999 1.75
$250,000 - $499,999 1.50
$500,000 - $999,999 1.25
$1,000,000 or more 0.70

We apply these concessions or agency commissions as a percent of the public
offering price per unit at the time of the transaction. The broker-dealer
concession or agency commission is 65% of the sales fee for secondary market
sales. For transactions involving unitholders of other unit investment trusts
who use their redemption or termination proceeds to purchase units of your
trust, the distribution fee is 1.30% of the public offering price per unit. No
distribution fee is paid to broker-dealers, investment advisers or other selling
firms in connection with unit sales in Fee Accounts subject to a Wrap Fee.

Broker-dealers and other firms that sell units of certain unit investment
trusts for which AAM acts as sponsor are eligible to receive additional
compensation for volume sales. The sponsor offers two separate volume
concession structures for certain trusts that are referred to as "Volume
Concession A" and "Volume Concession B." The trusts offered in this prospectus
are Volume Concession A trusts. Broker-dealers and other firms that sell units
of any Volume Concession A trust are eligible to receive the additional
compensation described below. Such payments will be in addition to the regular
concessions paid to firms as set forth in the applicable trust's prospectus.
The additional concession is based on total initial offering period sales of all
Volume Concession A trusts during a calendar quarter as set forth in the
following table:

INITIAL OFFERING PERIOD SALES VOLUME
DURING CALENDAR QUARTER CONCESSION
---------------------------------------------------------

Less than $10,000,000 0.000%
$10,000,000 but less than $25,000,000 0.050
$25,000,000 but less than $50,000,000 0.100
$50,000,000 but less than $75,000,000 0.110
$75,000,000 but less than $100,000,000 0.120
$100,000,000 but less than $250,000,000 0.125
$250,000,000 but less than $500,000,000 0.135
$500,000,000 or more 0.150

This volume concession will be paid on units of all Volume Concession A
trusts sold in the initial offering period, except as described below. For a
trust to be eligible for this additional Volume Concession A compensation for
calendar quarter sales, the trust's prospectus must include disclosure related
to this additional Volume Concession A compensation; a trust is not eligible for
this additional Volume Concession A compensation if the prospectus for such
trust does not include disclosure related to this additional Volume Concession A
compensation. Broker-dealer firms will not receive additional compensation
unless they sell at least $10.0 million of units of Volume Concession A trusts
during a calendar quarter. For example, if a firm sells $9.5 million of units
of Volume Concession A trusts in the initial offering period during a calendar
quarter, the firm will not receive any additional compensation with respect to
such trusts. Once a firm reaches a particular breakpoint during a quarter, the
firm will receive the stated volume concession on all initial offering period
sales of Volume Concession A trusts during the applicable quarter. For example,
if a firm sells $12.5 million of units of Volume Concession A trusts in the
initial offering period during a calendar quarter, the firm will receive
additional

32 Understanding Your Investment

compensation of 0.05% of $12.5 million and if a firm sells $27.0 million of
units of Volume Concession A trusts in the initial offering period during a
calendar quarter, the firm will receive additional compensation of 0.100% of
$27.0 million.

In addition, dealer firms will not receive volume concessions on the sale of
units which are not subject to a transactional sales charge. However, such
sales will be included in determining whether a firm has met the sales level
breakpoints for volume concessions subject to the policies of the related
selling firm. Secondary market sales of all unit trusts are excluded for
purposes of these volume concessions. We will pay these amounts out of our own
assets within a reasonable time following each calendar quarter.

Any sales fee discount is borne by the broker-dealer or selling firm out of
the distribution fee. We reserve the right to change the amount of concessions
or agency commissions from time to time.

We currently may provide, at our own expense and out of our own profits,
additional compensation and benefits to broker-dealers who sell units of your
trust and our other products. This compensation is intended to result in
additional sales of our products and/or compensate broker-dealers and financial
advisors for past sales. A number of factors are considered in determining
whether to pay these additional amounts. Such factors may include, but are not
limited to, the level or type of services provided by the intermediary, the
level or expected level of sales of our products by the intermediary or its
agents, the placing of our products on a preferred or recommended product list
and access to an intermediary's personnel. We may make these payments for
marketing, promotional or related expenses, including, but not limited to,
expenses of entertaining retail customers and financial advisors, advertising,
sponsorship of events or seminars, obtaining information about the breakdown of
unit sales among an intermediary's representatives or offices, obtaining shelf
space in broker-dealer firms and similar activities designed to promote the sale
of our products. We make such payments to a substantial majority of
intermediaries that sell our products. We may also make certain payments to, or
on behalf of, intermediaries to defray a portion of their costs incurred for the
purpose of facilitating unit sales, such as the costs of developing or
purchasing trading systems to process unit trades. Payments of such additional
compensation described in this paragraph and the volume concessions described
above, some of which may be characterized as "revenue sharing," may create an
incentive for financial intermediaries and their agents to sell or recommend our
products, including your trust, over other products. These arrangements will
not change the price you pay for your units.

We generally register units for sale in various states in the U.S. We do not
register units for sale in any foreign country. This prospectus does not
constitute an offer of units in any state or country where units cannot be
offered or sold lawfully. We may reject any order for units in whole or in
part.

We may gain or lose money when we hold units in the primary or secondary
market due to fluctuations in unit prices. The gain or loss is equal to the
difference between the price we pay for units and the price at which we sell or
redeem them. We may also gain or lose money when we deposit securities to
create units. The amount of our profit or loss on the initial deposit of
securities into your trust is shown in the "Notes to Portfolio" section for your
trust.

TAXES

This section summarizes some of the main U.S. federal income tax consequences
of owning units of your trust. This section is current as of the date of this
prospectus. Tax laws and interpretations change frequently, and these summaries
do not describe all of the tax consequences to all taxpayers. For example,
these summaries generally do not describe your situation if you are a
corporation, a non-U.S. person, a broker/dealer, or other investor with special
circumstances. In addition, this section does not describe your state, local or
foreign tax consequences.

This federal income tax summary is based in part on the advice of counsel to
the sponsor. The Internal Revenue Service could disagree with any conclusions
set forth in this section. In addition, our counsel was not asked to review,
and has not reached a conclusion with respect to the federal income tax
treatment of the assets to be deposited in your trust. This may not be
sufficient for you to use for the purpose of avoiding penalties under federal
tax law.

As with any investment, you should seek advice based on your individual
circumstances from your own tax advisor.

TRUST STATUS. Your trust intends to qualify as a "regulated investment
company" under the federal tax laws. If your trust qualifies as a regulated
investment company and distributes its income as required by the tax law, your
trust generally will not pay federal income taxes. An adverse federal income
tax audit of a partnership that the trust invests in could result in the trust
being required to pay federal income tax or pay a deficiency dividend (without
having received additional cash).

DISTRIBUTIONS. Trust distributions are generally taxable. After the end of
each year, you will receive a tax statement that separates your trust's
distributions into three categories, ordinary income distributions, capital gain
dividends and return of capital. Ordinary income distributions are generally
taxed at your ordinary tax rate, however, as further discussed below, certain
ordinary income distributions received from your trust may be taxed at the
capital gains tax rates. Generally, you will treat all capital gain dividends
as long-term capital gains regardless of how long you have owned your units. To
determine your actual tax liability for your capital gain dividends, you must
calculate your total net capital gain or loss for the tax year after considering
all of your other taxable transactions, as described below. In addition, your
trust may make distributions that represent a return of capital for tax purposes
and thus will generally not be taxable to you. The tax status of your
distributions from your trust is not affected by whether you reinvest your
distributions in additional units or receive them in cash. The income from your
trust that you must take into account for federal income tax purposes is not
reduced by amounts used to pay a deferred sales fee, if any. The tax laws may
require you to treat distributions made to you in January as if you had received
them on December 31 of the previous year. Income from your trust may also be
subject to a 3.8 percent "medicare tax". This tax generally applies to your net
investment income if your adjusted gross income exceeds certain threshold
amounts, which are $250,000 in the case of married couples filing joint returns
and $200,000 in the case of single individuals.

DIVIDENDS RECEIVED DEDUCTION. A corporation that owns units generally will
not be entitled to the dividends received deduction with respect to many
dividends received from your trust because the dividends received deduction is
generally not available

34 Understanding Your Investment

for distributions from regulated investment companies. However, certain
ordinary income dividends on units that are attributable to qualifying dividends
received by your trust from certain corporations may be reported by the trust as
being eligible for the dividends received deduction.

SALE OR REDEMPTION OF UNITS. If you sell or redeem your units, you will
generally recognize a taxable gain or loss. To determine the amount of this
gain or loss, you must subtract your tax basis in your units from the amount you
receive in the transaction. Your tax basis in your units is generally equal to
the cost of your units, generally including sales charges. In some cases,
however, you may have to adjust your tax basis after you purchase your units.

CAPITAL GAINS AND LOSSES AND CERTAIN ORDINARY INCOME DIVIDENDS. If you are
an individual, the maximum marginal stated federal tax rate for net capital gain
is generally 20% for taxpayers in the 39.6% tax bracket, 15% for taxpayers in
the 25%, 28%, 33% and 35% tax brackets and 0% for taxpayers in the 10% and 15%
tax brackets. Some portion of your capital gain dividends may be subject to
higher maximum marginal stated federal income tax rates. Capital gains may also
be subject to the "medicare tax" described above. Capital gain received from
assets held for more than one year that is considered "unrecaptured section 1250
gain" (which may be the case, for example, with some capital gains attributable
to equity interests in real estate investment trusts that constitute interests
in entities treated as real estate investment trusts for federal income tax
purposes) is taxed at a maximum stated tax rate of 25%. In the case of capital
gain dividends, the determination of which portion of the capital gain dividend,
if any, is subject to the 25% tax rate, will be made based on rules prescribed
by the United States Treasury.

Net capital gain equals net long-term capital gain minus net short-term
capital loss for the taxable year. Capital gain or loss is long-term if the
holding period for the asset is more than one year and is short-term if the
holding period for the asset is one year or less. You must exclude the date you
purchase your units to determine your holding period. However, if you receive a
capital gain dividend from your trust and sell your unit at a loss after holding
it for six months or less, the loss will be recharacterized as long-term capital
loss to the extent of the capital gain dividend received. The tax rates for
capital gains realized from assets held for one year or less are generally the
same as for ordinary income. The Internal Revenue Code treats certain capital
gains as ordinary income in special situations.

Ordinary income dividends received by an individual unitholder from a
regulated investment company such as your trust are generally taxed at the same
rates that apply to net capital gain (as discussed above), provided certain
holding period requirements are satisfied and provided the dividends are
attributable to qualifying dividends received by your trust itself.
Distributions with respect to shares in real estate investment trusts are
qualifying dividends only in limited circumstances. Your trust will provide
notice to its unitholders of the amount of any distribution which may be taken
into account as a dividend which is eligible for the capital gains tax rates.

IN-KIND DISTRIBUTIONS. Under certain circumstances, as described in this
prospectus, you may receive an in-kind distribution of trust securities when you
redeem units or when your trust terminates. This distribution will be treated
as a sale for federal income tax purposes and you will generally recognize gain
or loss, generally based on the value at that time of the securities and the
amount of cash received. The Internal Revenue

Understanding Your Investment 35

Service could however assert that a loss could not be currently deducted.

EXCHANGES. If you elect to have your proceeds from your trust rolled over
into a future trust, the exchange would generally be considered a sale for
federal income tax purposes.

DEDUCTIBILITY OF TRUST EXPENSES. Expenses incurred and deducted by your
trust will generally not be treated as income taxable to you. In some cases,
however, you may be required to treat your portion of these trust expenses as
income. In these cases you may be able to take a deduction for these expenses.
However, certain miscellaneous itemized deductions, such as investment expenses,
may be deducted by individuals only to the extent that all of these deductions
exceed 2% of the individual's adjusted gross income. Some individuals may also
be subject to further limitations on the amount of their itemized deductions,
depending on their income.

FOREIGN TAX CREDIT. If your trust invests in any foreign securities, the tax
statement that you receive may include an item showing foreign taxes your trust
paid to other countries. In this case, dividends taxed to you will include your
share of the taxes your trust paid to other countries. You may be able to
deduct or receive a tax credit for your share of these taxes.

INVESTMENTS IN CERTAIN FOREIGN CORPORATIONS. If your trust holds an equity
interest in any "passive foreign investment companies" ("PFICs"), which are
generally certain foreign corporations that receive at least 75% of their annual
gross income from passive sources (such as interest, dividends, certain rents
and royalties or capital gains) or that hold at least 50% of their assets in
investments producing such passive income, the trust could be subject to U.S.
federal income tax and additional interest charges on gains and certain
distributions with respect to those equity interests, even if all the income or
gain is timely distributed to its unitholders. Your trust will not be able to
pass through to its unitholders any credit or deduction for such taxes. Your
trust may be able to make an election that could ameliorate these adverse tax
consequences. In this case, your trust would recognize as ordinary income any
increase in the value of such PFIC shares, and as ordinary loss any decrease in
such value to the extent it did not exceed prior increases included in income.
Under this election, your trust might be required to recognize in a year income
in excess of its distributions from PFICs and its proceeds from dispositions of
PFIC stock during that year, and such income would nevertheless be subject to
the distribution requirement and would be taken into account for purposes of the
4% excise tax. Dividends paid by PFICs are not treated as qualified dividend
income.

FOREIGN INVESTORS. If you are a foreign investor (i.e., an investor other
than a U.S. citizen or resident or a U.S. corporation, partnership, estate or
trust), you should be aware that, generally, subject to applicable tax treaties,
distributions from your trust will be characterized as dividends for federal
income tax purposes (other than dividends which your trust properly reports as
capital gain dividends) and will be subject to U.S. income taxes, including
withholding taxes, subject to certain exceptions described below. However,
distributions received by a foreign investor from your trust that are properly
reported by your trust as capital gain dividends may not be subject to U.S.
federal income taxes, including withholding taxes, provided that your trust
makes certain elections and certain other conditions are met. In addition,
distributions in respect of units may be subject to a U.S. withholding tax of
30% in the case

36 Understanding Your Investment

of distributions to (i) certain non-U.S. financial institutions that have not
entered into an agreement with the U.S. Treasury to collect and disclose certain
information and are not resident in a jurisdiction that has entered into such an
agreement with the U.S. Treasury and (ii) certain other non-U.S. entities that
do not provide certain certifications and information about the entity's U.S.
owners. Dispositions of units by such persons may be subject to such
withholding after December 31, 2018. You should also consult your tax advisor
with respect to other U.S. tax withholding and reporting requirements.

EXPENSES

Your trust will pay various expenses to conduct its operations. The "Fees
and Expenses" section of the "Investment Summary" in this prospectus shows the
estimated amount of these expenses.

The sponsor will receive a fee from your trust for creating and developing
the trust, including determining the trust's objectives, policies, composition
and size, selecting service providers and information services and for providing
other similar administrative and ministerial functions. This "creation and
development fee" is a charge of $0.05 per unit. The trustee will deduct this
amount from your trust's assets as of the close of the initial offering period.
No portion of this fee is applied to the payment of distribution expenses or as
compensation for sales efforts. This fee will not be deducted from proceeds
received upon a repurchase, redemption or exchange of units before the close of
the initial public offering period.

Your trust will pay a fee to the trustee for its services. The trustee also
benefits when it holds cash for your trust in non-interest bearing accounts.
Your trust will reimburse us as supervisor, evaluator and sponsor for providing
portfolio supervisory services, for evaluating your portfolio and for providing
bookkeeping and administrative services. Our reimbursements may exceed the
costs of the services we provide to your trust but will not exceed the costs of
services provided to all of our unit investment trusts in any calendar year.
All of these fees may adjust for inflation without your approval.

Your trust will also pay its general operating expenses. Your trust may pay
expenses such as trustee expenses (including legal and auditing expenses),
various governmental charges, fees for extraordinary trustee services, costs of
taking action to protect your trust, costs of indemnifying the trustee and the
sponsor, legal fees and expenses, expenses incurred in contacting you and costs
incurred to reimburse the trustee for advancing funds to meet distributions.
Your trust may pay the costs of updating its registration statement each year.
Your trust will pay a license fee for the use of certain strategies, service
marks, trademarks, trade names and/or other property of Rothschild. The trustee
will generally pay trust expenses from distributions received on the securities
but in some cases may sell securities to pay trust expenses.

UNITHOLDERS
ADVISORS DISCIPLINED TRUST 1609

We have audited the accompanying statement of financial condition, including the
trust portfolios on pages __, __, __, __, __ and __ of Advisors Disciplined
Trust 1609, as of ___________, 2016, the initial date of deposit. The
statements of financial condition are the responsibility of the trust's sponsor.
Our responsibility is to express an opinion on these statements of financial
condition based on our audits.

We conducted our audits in accordance with auditing standards of the Public
Company Accounting Oversight Board (United States). Those standards require
that we plan and perform the audits to obtain reasonable assurance about whether
the statements of financial condition are free of material misstatement. We
were not engaged to perform audits of the trusts' internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the trusts' internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statements of financial condition, assessing the accounting principles used
and significant estimates made by the sponsor, as well as evaluating the overall
financial statement presentation. Our procedures included confirmation with The
Bank of New York Mellon, trustee, of cash or an irrevocable letter of credit
deposited for the purchase of securities as shown in the statements of financial
condition as of ___________, 2016. We believe that our audits of the statements
of financial condition provides a reasonable basis for our opinion.

In our opinion, the statements of financial condition referred to above present
fairly, in all material respects, the financial position of Advisors Disciplined
Trust 1609 as of ___________, 2016, in conformity with accounting principles
generally accepted in the United States of America.

GENERAL INFORMATION

Each trust is one of a series of separate unit investment trusts created
under the name Advisors Disciplined Trust and registered under the Investment
Company Act of 1940. Each trust was created as a common law trust on the
inception date described in the prospectus under the laws of the state of
New York. Each trust was created under a trust agreement among Advisors Asset
Management, Inc. (as sponsor/depositor, evaluator and supervisor) and The Bank
of New York Mellon (as trustee).

When your trust was created, the sponsor delivered to the trustee
securities or contracts for the purchase thereof for deposit in your trust and
the trustee delivered to the sponsor documentation evidencing the ownership of
units of your trust. At the close of the New York Stock Exchange on your
trust's inception date, the number of units may be adjusted so that the public
offering price per unit equals $10. The number of units, fractional interest of
each unit in your trust and estimated income distributions per unit will
increase or decrease to the extent of any adjustment. Additional units of each
trust may be issued from time to time by depositing in your trust additional
securities (or contracts for the purchase thereof together with cash or
irrevocable letters of credit) or cash (including a letter of credit or the
equivalent) with instructions to purchase additional securities. As additional
units are issued by your trust as a result of the deposit of additional
securities by the sponsor, the aggregate value of the securities in your trust
will be increased and the fractional undivided interest in your trust
represented by each unit will be decreased. The sponsor may continue to make
additional deposits of securities into your trust, provided that such additional
deposits will be in amounts, which will generally maintain the existing
relationship among the shares of the securities in your trust. Thus, although
additional units will be issued, each unit will generally continue to represent
the same number of shares of each security. If the sponsor deposits cash to
purchase additional securities, existing and new investors may experience a
dilution of their investments and a reduction in their anticipated income
because of fluctuations in the prices of the securities between the time of the
deposit and the purchase of the securities and because your trust will pay any
associated brokerage fees.

The trustee has not participated in the selection of the securities
deposited in your trust and has no responsibility for the composition of your
trust's portfolio.

Each unit initially offered represents an undivided interest in the related
trust. To the extent that any units are redeemed by the trustee or additional
units are issued as a result of additional securities being deposited by the
sponsor, the fractional undivided interest in your trust represented by each
unredeemed unit will increase or decrease accordingly, although the actual
interest in such trust represented by such fraction will remain unchanged.
Units will remain outstanding until redeemed upon tender to the trustee by
unitholders, which may include the sponsor, or until the termination of the
trust agreement.

Your trust consists of (a) the securities listed under "Portfolio" in the
prospectus as may continue to be held from time to time in your trust, (b) any
additional securities acquired and held by your trust pursuant to the provisions
of the trust agreement and (c) any cash held in the accounts of your trust.
Neither the sponsor nor the trustee shall be liable in any way for any

-2-

failure in any of the securities. However, should any contract for the purchase
of any of the securities initially deposited in your trust fail, the sponsor
will, unless substantially all of the moneys held in your trust to cover such
purchase are reinvested in substitute securities in accordance with the trust
agreement, refund the cash and sales fee attributable to such failed contract to
all unitholders on the next distribution date.

INVESTMENT OBJECTIVE AND POLICIES

The prospectus provides additional information regarding your trust's
objective and investment strategy. There is, of course, no guarantee that your
trust will achieve its objective.

Your trust is a unit investment trust and is not an "actively managed"
fund. Traditional methods of investment management for a managed fund typically
involve frequent changes in a portfolio of securities on the basis of economic,
financial and market analysis. The portfolio of your trust, however, will not
be actively managed and therefore the adverse financial condition of an issuer
will not necessarily require the sale of its securities from a portfolio.

The sponsor may not alter the portfolio of your trust by the purchase, sale
or substitution of securities, except in special circumstances as provided in
the trust agreement. Thus, the assets of your trust will generally remain
unchanged under normal circumstances. The trust agreement provides that the
sponsor may (but need not) direct the trustee to dispose of a security in
certain events such as the issuer having defaulted on the payment on any of its
outstanding obligations or the price of a security has declined to such an
extent or other such credit factors exist so that in the opinion of the
supervisor the retention of such securities would be detrimental to your trust.

If a public tender offer has been made for a security or a merger,
acquisition or similar transaction has been announced affecting a security, the
trustee may either sell the security or accept a tender offer if the supervisor
determines that the action is in the best interest of unitholders. The trustee
will distribute any cash proceeds to unitholders. If an offer by the issuer of
any of the portfolio securities or any other party is made to issue new
securities, or to exchange securities, for trust portfolio securities, the
trustee will at the direction of the sponsor, vote for or against, or accept or
reject, any offer for new or exchanged securities or property in exchange for a
trust portfolio security. If any such issuance, exchange or substitution occurs
(regardless of any action or rejection by your trust), any securities and/or
property received will be deposited into your trust and will be promptly sold by
the trustee pursuant to the sponsor's direction, unless the sponsor advises the
trustee to keep such securities or property. If any contract for the purchase
of securities fails, the sponsor will refund the cash and sales fee attributable
to the failed contract to unitholders on or before the next distribution date
unless substantially all of the moneys held to cover the purchase are reinvested
in substitute securities in accordance with the trust agreement. The sponsor may
direct the reinvestment of security sale proceeds if the sale is the direct
result of serious adverse credit factors which, in the opinion of the sponsor,
would make retention of the securities detrimental to your trust. In such a
case, the sponsor may, but is not obligated to, direct the reinvestment of sale
proceeds in any other securities that meet the criteria for inclusion in your
trust on your trust's inception date. The sponsor may also instruct the trustee
to take action necessary to ensure that the portfolio continues to satisfy the
qualifications of a regulated investment company.

-3-

The trustee may sell securities, designated by the supervisor, from your
trust for the purpose of redeeming units of such trust tendered for redemption
and the payment of expenses.

In addition, if your trust has elected to be taxed as a regulated
investment company, the trustee may dispose of certain securities and take such
further action as may be needed from time to time to ensure that your trust
continues to satisfy the qualifications of a regulated investment company,
including the requirements with respect to diversification under Section 851 of
the Internal Revenue Code, and as may be needed from time to time to avoid the
imposition of any tax on your trust or undistributed income of your trust as a
regulated investment company.

Proceeds from the sale of securities (or any securities or other property
received by your trust in exchange for securities) are credited to the Capital
Account of your trust for distribution to unitholders or to meet redemptions.
Except for failed securities and as provided herein, in the prospectus or in the
trust agreement, the acquisition by your trust of any securities other than the
portfolio securities is prohibited.

Because certain of the securities in certain of the trusts may from time to
time under certain circumstances be sold or otherwise liquidated and because the
proceeds from such events will be distributed to unitholders and will not be
reinvested, no assurance can be given that your trust will retain for any length
of time its present size and composition. Neither the sponsor nor the trustee
shall be liable in any way for any default, failure or defect in any security.
In the event of a failure to deliver any security that has been purchased for
your trust under a contract ("Failed Securities"), the sponsor is authorized
under the trust agreement to direct the trustee to acquire other securities
("Replacement Securities") to make up the original corpus of such trust.

The Replacement Securities must be purchased within 20 days after delivery
of the notice that a contract to deliver a security will not be honored and the
purchase price may not exceed the amount of funds reserved for the purchase of
the Failed Securities. The Replacement Securities must be equity securities of
the type selected for your trust and must not adversely affect the federal
income tax status of your trust. Whenever a Replacement Security is acquired
for your trust, the trustee shall notify all unitholders of your trust of the
acquisition of the Replacement Security and shall, on the next monthly
distribution date which is more than 30 days thereafter, make a pro rata
distribution of the amount, if any, by which the cost to your trust of the
Failed Security exceeded the cost of the Replacement Security. Once all of the
securities in your trust are acquired, the trustee will have no power to vary
the investments of your trust, i.e., the trustee will have no managerial power
to take advantage of market variations to improve a unitholder's investment.

If the right of limited substitution described in the preceding paragraphs
is not utilized to acquire Replacement Securities in the event of a failed
contract, the sponsor will refund the sales fee attributable to such Failed
Securities to all unitholders of your trust and the trustee will distribute the
cash attributable to such Failed Securities not more than 30 days after the date
on which the trustee would have been required to purchase a Replacement
Security. In addition, unitholders should be aware that, at the time of receipt
of such cash, they may not be able to reinvest such proceeds in other securities
at a return equal to or in excess of the return which such proceeds would have
earned for unitholders of such trust.

-4-

In the event that a Replacement Security is not acquired by your trust, the
income for such trust may be reduced.

To the best of the sponsor's knowledge, there is no litigation pending as
of your trust's inception in respect of any security that might reasonably be
expected to have a material adverse effect on your trust. At any time after
your trust's inception, litigation may be instituted on a variety of grounds
with respect to the securities. The sponsor is unable to predict whether any
such litigation may be instituted, or if instituted, whether such litigation
might have a material adverse effect on your trust. The sponsor and the trustee
shall not be liable in any way for any default, failure or defect in any
security.

RISK FACTORS

MARKET RISK. Because your trust may invest in stocks, you should understand
the risks of investing in stocks before purchasing units. These risks include
the risk that the financial condition of the company or the general condition of
the stock market may worsen and the value of the stocks (and therefore units)
will fall. Stocks are especially susceptible to general stock market movements.
The value of stocks often rises or falls rapidly and unpredictably as market
confidence and perceptions of companies change. These perceptions are based on
factors including expectations regarding government economic policies,
inflation, interest rates, economic expansion or contraction, political climates
and economic or banking crises. The value of units will fluctuate with the value
of the stocks in your trust and may be more or less than the price you
originally paid for your units. As with any investment, we cannot guarantee that
the performance of your trust will be positive over any period of time. Because
your trust is unmanaged, the Trustee will not sell stocks in response to market
fluctuations as is common in managed investments. In addition, because some
trusts hold a relatively small number of stocks, you may encounter greater
market risk than in a more diversified investment.

EUROPEAN ISSUERS. Your trust may invest in securities issued by companies
in Europe. Your trust may therefore subject to certain risks associated
specifically with Europe. A significant number of countries in Europe are
member states in the European Union, and the member states no longer control
their own monetary policies by directing independent interest rates for their
currencies. In these member states, the authority to direct monetary policies
including money supply and official interest rates for the Euro is exercised by
the European Central Bank. Furthermore, the European sovereign debt crisis and
the related austerity measures in certain countries have had, and continue to
have, a significant impact on the economies of certain European countries and
their future economic outlooks.

JAPANESE ISSUER RISK. Your trust may invest in securities issued by
companies in Japan. At times, the growth of Japan's economy has lagged that of
many of its Asian neighbors and other major developed economies. The Japanese
economy is heavily dependent on international trade and has sometimes been
adversely affected by trade tariffs, other protectionist measures, competition
from emerging economies and the economic conditions of its trading partners.
China has become an important trading partner with Japan, yet the countries'
political relationship has often been strained. Should political tension
increase, it could adversely affect the economy, especially the export sector,
and destabilize the region as a whole. Japan also remains heavily

-5-

dependent on oil imports and higher commodity prices could have a negative
impact on the economy. The Japanese economy faces several other concerns,
including a financial system with large levels of nonperforming loans, over-
leveraged corporate balance sheets, extensive cross-ownership by major
corporations, a changing corporate governance structure, and large government
deficits. These issues may cause a slowdown of the Japanese economy. The
Japanese yen has fluctuated widely at times and any increase in its value may
cause a decline in exports that could weaken the Japanese economy. Japan has, in
the past, intervened in the currency markets to attempt to maintain or reduce
the value of the yen. Japanese intervention in the currency markets could cause
the value of the yen to fluctuate sharply and unpredictably and could cause
losses to investors. Japan has an aging workforce and has experienced a
significant population decline in recent years.

FOREIGN ISSUERS. Because your trust may invest in foreign stocks, they
involve additional risks that differ from an investment in domestic stocks.
Investments in foreign securities may involve a greater degree of risk than
those in domestic securities. There is generally less publicly available
information about foreign companies in the form of reports and ratings similar
to those that are published about issuers in the United States. Also, foreign
issuers are generally not subject to uniform accounting, auditing and financial
reporting requirements comparable to those applicable to United States issuers.
With respect to certain foreign countries, there is the possibility of adverse
changes in investment or exchange control regulations, expropriation,
nationalization or confiscatory taxation, limitations on the removal of funds or
other assets of your trust, political or social instability, or diplomatic
developments which could affect United States investments in those countries.
Moreover, industrial foreign economies may differ favorably or unfavorably from
the United States' economy in terms of growth of gross national product, rate of
inflation, capital reinvestment, resource self-sufficiency and balance of
payments position. Foreign securities markets are generally not as developed or
efficient as those in the United States. While growing in volume, they usually
have substantially less volume than the New York Stock Exchange, and securities
of some foreign issuers are less liquid and more volatile than securities of
comparable United States issuers. Fixed commissions on foreign exchanges are
generally higher than negotiated commissions on United States exchanges. There
is generally less government supervision and regulation of securities exchanges,
brokers and listed issuers than in the United States.

Your trust may also involve the risk that fluctuations in exchange rates
between the U.S. dollar and foreign currencies may negatively affect the value
of the stocks. For example, if a foreign stock rose 10% in price but the U.S.
dollar gained 5% against the related foreign currency, a U.S. investor's return
would be reduced to about 5%. This is because the foreign currency would "buy"
fewer dollars or, conversely, a dollar would buy more of the foreign currency.
Many foreign currencies have fluctuated widely against the U.S. dollar for a
variety of reasons such as supply and demand of the currency, investor
perceptions of world or country economies, political instability, currency
speculation by institutional investors, changes in government policies, buying
and selling of currencies by central banks of countries, trade balances and
changes in interest rates. Your trust's foreign currency transactions will be
conducted with foreign exchange dealers acting as principals on a spot (i.e.,
cash) buying basis. These dealers realize a profit based on the difference
between the price at which they buy the currency (bid price) and the price at
which they sell the currency (offer price). The evaluator will

-6-

estimate the currency exchange rates based on current activity in the related
currency exchange markets, however, due to the volatility of the markets and
other factors, the estimated rates may not be indicative of the rate your trust
might obtain had the trustee sold the currency in the market at that time.

DIVIDENDS. Stocks represent ownership interests in a company and are not
obligations of the company. Common stockholders have a right to receive payments
from the company that is subordinate to the rights of creditors, bondholders or
preferred stockholders of the company. This means that common stockholders have
a right to receive dividends only if a company's board of directors declares a
dividend and the company has provided for payment of all of its creditors,
bondholders and preferred stockholders. If a company issues additional debt
securities or preferred stock, the owners of these securities will have a claim
against the company's assets before common stockholders if the company declares
bankruptcy or liquidates its assets even though the common stock was issued
first. As a result, the company may be less willing or able to declare or pay
dividends on its common stock.

ADDITIONAL DEPOSITS. The trust agreement authorizes the sponsor to
increase the size of your trust and the number of units thereof by the deposit
of additional securities, or cash (including a letter of credit or the
equivalent) with instructions to purchase additional securities, in such trust
and the issuance of a corresponding number of additional units. In connection
with these deposits, existing and new investors may experience a dilution of
their investments and a reduction in their anticipated income because of
fluctuations in the prices of the securities between the time of the deposit and
the purchase of the securities and because your trust will pay the associated
brokerage fees and other acquisition costs.

ADMINISTRATION OF YOUR TRUST

DISTRIBUTIONS TO UNITHOLDERS. Income received by your trust is credited by
the trustee to the Income Account for your trust. All other receipts are
credited by the trustee to a separate Capital Account for your trust. The
trustee will normally distribute income received by your trust on each
distribution date or shortly thereafter to unitholders of record on the
preceding record date. Your trust generally pays distributions from its Income
Account (pro-rated on an annual basis) along with any excess balance from the
Capital Account on each monthly distribution date to unitholders of record on
the preceding record date as described in greater detail below. All
distributions will be net of applicable expenses. The amount of your
distributions will vary from time to time as companies change their dividends or
trust expenses change. Your trust will also generally make required
distributions or distributions to avoid imposition of tax at the end of each
year if it has elected to be taxed as a "regulated investment company" for
federal tax purposes. Excess amounts from the Capital Account of your trust, if
any, will be distributed at least annually to the unitholders then of record.
Proceeds received from the disposition of any of the securities after a record
date and prior to the following distribution date will be held in the Capital
Account and not distributed until the next distribution date applicable to the
Capital Account. The trustee shall not be required to make a distribution from
the Capital Account unless the cash balance on deposit therein available for
distribution shall be sufficient to distribute at least $1.00 per 100 units.
The trustee is not required to pay interest on funds held in

-7-

the Capital or Income Accounts (but may itself earn interest thereon and
therefore benefits from the use of such funds).

The distribution to the unitholders as of each record date will be made on
the following distribution date or shortly thereafter. When your trust receives
dividends from a portfolio security, the trustee credits the dividends to the
trust's accounts. In an effort to make relatively regular income distributions,
your trust's distribution from the Income Account on each distribution date to
each unitholder is equal to such unitholder's pro rata share of the cash balance
in the Income Account calculated on the basis of a fraction (the numerator of
which is one and the denominator of which is the total number of distribution
dates per year) of the estimated annual income to the trust for the ensuing
twelve months computed as of the close of business on the record date
immediately preceding such distribution after deduction of (1) the fees and
expenses then deductible pursuant to the trust agreement and (2) the trustee's
estimate of other expenses properly chargeable to the Income Account pursuant to
the trust agreement which have accrued as of such record date or are otherwise
properly attributable to the period to which such distribution relates. Because
your trust does not receive dividends from the portfolio securities at a
constant rate throughout the year, your trust's income distributions to
unitholders may be more or less than the amount credited to your trust accounts
as of the record date. In the event that the amount on deposit in the Income
Account is not sufficient for the payment of the amount intended to be
distributed to unitholders on the basis of the computation described above, the
trustee is authorized to advance its own funds and cause to be deposited in and
credited to the Income Account such amounts as may be required to permit payment
of the related distribution to be made as described above. In such an event,
the trustee shall be entitled to be reimbursed, without interest, out of income
payments received by the trust subsequent to the date of such advance. Any such
advance shall be reflected in the Income Account until repaid. A person will
become the owner of units, and thereby a unitholder of record, on the date of
settlement provided payment has been received. Persons who purchase units will
commence receiving distributions only after such person becomes a record owner.
Notification to the trustee of the transfer of units is the responsibility of
the purchaser, but in the normal course of business the selling broker-dealer
provides such notice.

The trustee will periodically deduct from the Income Account of your trust
and, to the extent funds are not sufficient therein, from the Capital Account of
your trust amounts necessary to pay the expenses of your trust. The trustee
also may withdraw from said accounts such amounts, if any, as it deems necessary
to establish a reserve for any governmental charges payable out of your trust.
Amounts so withdrawn shall not be considered a part of your trust's assets until
such time as the trustee shall return all or any part of such amounts to the
appropriate accounts. In addition, the trustee may withdraw from the Income and
Capital Accounts of your trust such amounts as may be necessary to cover
redemptions of units.

DISTRIBUTION REINVESTMENT. Unitholders may reinvest distributions into
additional units of their trust without a sales fee. Your trust will pay any
deferred sales fee and creation and development fee per unit regardless of any
sales fee discounts. However, if you are eligible to receive a discount such
that the sales fee you must pay is less than the applicable deferred sales fee
and creation and development fee, you will be credited the difference between
your sales fee and the deferred sales fee and the creation and development fee
at the time you buy your units.

-8-

Accordingly, if you reinvest distributions into additional units of your trust,
you will be credited the amount of any remaining deferred sales fee and creation
and development fee on such units at the time of reinvestment.

STATEMENTS TO UNITHOLDERS. With each distribution, the trustee will
furnish to each unitholder a statement of the amount of income and the amount of
other receipts, if any, which are being distributed, expressed in each case as a
dollar amount per unit.

The accounts of your trust are required to be audited annually, at the
related trust's expense, by independent public accountants designated by the
sponsor, unless the sponsor determines that such an audit would not be in the
best interest of the unitholders of your trust. The accountants' report will be
furnished by the trustee to any unitholder upon written request. Within a
reasonable period of time after the end of each calendar year, the trustee shall
furnish to each person who at any time during the calendar year was a unitholder
of your trust a statement, covering the calendar year, setting forth for your
trust:

(A) As to the Income Account:

(1) the amount of income received on the securities (including income
received as a portion of the proceeds of any disposition of
securities);

(2) the amounts paid for purchases of replacement securities or for
purchases of securities otherwise pursuant to the trust
agreement, if any, and for redemptions;

(3) the deductions, if any, from the Income Account for payment into
the Reserve Account;

(4) the deductions for applicable taxes and fees and expenses of the
trustee, the depositor, the evaluator, the supervisor, counsel,
auditors and any other expenses paid by your trust;

(5) the amounts reserved for purchases of contract securities, for
purchases made pursuant to replace failed contract securities or
for purchases of securities otherwise pursuant to the trust
agreement, if any;

(6) the deductions for payment of the sponsors's expenses of
maintaining the registration of the trust units, if any;

(7) the aggregate distributions to unitholders; and

(8) the balance remaining after such deductions and distributions,
expressed both as a total dollar amount and as a dollar amount
per unit outstanding on the last business day of such calendar
year;

(B) As to the Capital Account:

-9-

(1) the net proceeds received due to sale, maturity, redemption,
liquidation or disposition of any of the securities, excluding
any portion thereof credited to the Income Account;

(2) the amount paid for purchases of replacement securities or for
purchases of securities otherwise pursuant to the trust
agreement, if any, and for redemptions;

(3) the deductions, if any, from the Capital Account for payments
into the Reserve Account;

(4) the deductions for payment of applicable taxes and fees and
expenses of the trustee, the depositor, the evaluator, the
supervisor, counsel, auditors and any other expenses paid by your
trust;

(5) the deductions for payment of the depositor's expenses of
organizing your trust;

(6) the amounts reserved for purchases of contract securities, for
purchases made pursuant to replace failed contract securities or
for purchases of securities otherwise pursuant to the trust
agreement, if any;

(7) the deductions for payment of deferred sales fee and creation and
development fee, if any;

(8) the deductions for payment of the sponsor's expenses of
maintaining the registration of the trust units, if any;

(9) the aggregate distributions to unitholders; and

(10) the balance remaining after such distributions and deductions,
expressed both as a total dollar amount and as a dollar amount
per unit outstanding on the last business day of such calendar
year; and

(1) a list of the securities held as of the last business day of such
calendar year and a list which identifies all securities sold or
other securities acquired during such calendar year, if any;

(2) the number of units outstanding on the last business day of such
calendar year;

(3) the unit value based on the last trust evaluation of such trust
made during such calendar year; and

-10-

(4) the amounts actually distributed during such calendar year from
the Income and Capital Accounts, separately stated, expressed
both as total dollar amounts and as dollar amounts per unit
outstanding on the record dates for such distributions.

RIGHTS OF UNITHOLDERS. A unitholder may at any time tender units to the
trustee for redemption. The death or incapacity of any unitholder will not
operate to terminate your trust nor entitle legal representatives or heirs to
claim an accounting or to bring any action or proceeding in any court for
partition or winding up of your trust. No unitholder shall have the right to
control the operation and management of your trust in any manner, except to vote
with respect to the amendment of the trust agreement or termination of your
trust.

AMENDMENT AND TERMINATION. The trust agreement may be amended from time to
time by the sponsor and trustee or their respective successors, without the
consent of any of the unitholders, (i) to cure any ambiguity or to correct or
supplement any provision which may be defective or inconsistent with any other
provision contained in the trust agreement, (ii) to make such other provision in
regard to matters or questions arising under the trust agreement as shall not
materially adversely affect the interests of the unitholders or (iii) to make
such amendments as may be necessary (a) for your trust to continue to qualify as
a regulated investment company for federal income tax purposes if your trust has
elected to be taxed as such under the United States Internal Revenue Code of
1986, as amended, or (b) to prevent your trust from being deemed an association
taxable as a corporation for federal income tax purposes if your trust has not
elected to be taxed as a regulated investment company under the United States
Internal Revenue Code of 1986, as amended. The trust agreement may not be
amended, however, without the consent of all unitholders then outstanding, so as
(1) to permit, except in accordance with the terms and conditions thereof, the
acquisition hereunder of any securities other than those specified in the
schedules to the trust agreement or (2) to reduce the percentage of units the
holders of which are required to consent to certain of such amendments. The
trust agreement may not be amended so as to reduce the interest in your trust
represented by units without the consent of all affected unitholders. Except
for the amendments, changes or modifications described above, neither the
sponsor nor the trustee may consent to any other amendment, change or
modification of the trust agreement without the giving of notice and the
obtaining of the approval or consent of unitholders representing at least 66
2/3% of the units then outstanding of the affected trust. No amendment may
reduce the aggregate percentage of units the holders of which are required to
consent to any amendment, change or modification of the trust agreement without
the consent of the unitholders of all of the units then outstanding of the
affected trust and in no event may any amendment be made which would (1) alter
the rights to the unitholders as against each other, (2) provide the trustee
with the power to engage in business or investment activities other than as
specifically provided in the trust agreement, (3) adversely affect the tax
status of your trust for federal income tax purposes or result in the units
being deemed to be sold or exchanged for federal income tax purposes or (4)
unless your trust has elected to be taxed as a regulated investment company for
federal income tax purposes, result in a variation of the investment of
unitholders in your trust. The trustee will notify unitholders of the substance
of any such amendment.

-11-

The trust agreement provides that your trust shall terminate upon the
liquidation, redemption or other disposition of the last of the securities held
in your trust but in no event is it to continue beyond the mandatory termination
date. If the value of your trust shall be less than the applicable minimum
value stated in the prospectus (generally 40% of the total value of securities
deposited in your trust during the initial offering period), the trustee may, in
its discretion, and shall, when so directed by the sponsor, terminate your
trust. Your trust may be terminated at any time by the holders of units
representing 66 2/3% of the units thereof then outstanding. In addition, the
sponsor may terminate your trust if it is based on a security index and the
index is no longer maintained. Your trust will be liquidated by the trustee in
the event that a sufficient number of units of your trust not yet sold are
tendered for redemption by the sponsor, so that the net worth of your trust
would be reduced to less than 40% of the value of the securities at the time
they were deposited in your trust. If your trust is liquidated because of the
redemption of unsold units by the sponsor, the sponsor will refund to each
purchaser of units the entire sales fee paid by such purchaser.

Beginning nine business days prior to, but no later than, the scheduled
termination date described in the prospectus, the trustee may begin to sell all
of the remaining underlying securities on behalf of unitholders in connection
with the termination of your trust. The sponsor may assist the trustee in these
sales and receive compensation to the extent permitted by applicable law. The
sale proceeds will be net of any incidental expenses involved in the sales.

The sponsor will generally instruct the trustee to sell the securities as
quickly as practicable during the termination proceedings without in its
judgment materially adversely affecting the market price of the securities, but
it is expected that all of the securities will in any event be disposed of
within a reasonable time after your trust's termination. The sponsor does not
anticipate that the period will be longer than one month, and it could be as
short as one day, depending on the liquidity of the securities being sold. The
liquidity of any security depends on the daily trading volume of the security
and the amount that the sponsor has available for sale on any particular day.
Of course, no assurances can be given that the market value of the securities
will not be adversely affected during the termination proceedings.

Approximately thirty days prior to termination of your trust, the trustee
will notify unitholders of the termination and provide a form allowing
qualifying unitholders to elect an in-kind distribution. A unitholder who owns
the minimum number of units described in the prospectus may request an in-kind
distribution from the trustee instead of cash. The trustee will make an in-kind
distribution through the distribution of each of the securities of your trust in
book entry form to the account of the unitholder's bank or broker-dealer at
Depository Trust Company. The unitholder will be entitled to receive whole
shares of each of the securities comprising the portfolio of your trust and cash
from the Capital Account equal to the fractional shares to which the unitholder
is entitled. The trustee may adjust the number of shares of any security
included in a unitholder's in-kind distribution to facilitate the distribution
of whole shares. The sponsor may terminate the in-kind distribution option at
any time upon notice to the unitholders. Special federal income tax
consequences will result if a unitholder requests an in-kind distribution.

-12-

Within a reasonable period after termination, the trustee will sell any
securities remaining in your trust and, after paying all expenses and charges
incurred by your trust, will distribute to unitholders thereof their pro rata
share of the balances remaining in the Income and Capital Accounts of your
trust.

The sponsor may, but is not obligated to, offer for sale units of a
subsequent series of your trust at approximately the time of the mandatory
termination date. If the sponsor does offer such units for sale, unitholders
may be given the opportunity to purchase such units at a public offering price
that includes a reduced sales fee. There is, however, no assurance that units
of any new series of your trust will be offered for sale at that time, or if
offered, that there will be sufficient units available for sale to meet the
requests of any or all unitholders.

THE TRUSTEE. The trustee is The Bank of New York Mellon, a trust company
organized under the laws of New York. The Bank of New York Mellon has its
principal unit investment trust division offices at 2 Hanson Place, 12th Floor,
Brooklyn, New York 11217, (800) 848-6468. The Bank of New York Mellon is subject
to supervision and examination by the Superintendent of Banks of the State of
New York and the Board of Governors of the Federal Reserve System, and its
deposits are insured by the Federal Deposit Insurance Corporation to the extent
permitted by law.

The trustee, whose duties are ministerial in nature, has not participated
in selecting the portfolio of any trust. In accordance with the trust
agreement, the trustee shall keep records of all transactions at its office.
Such records shall include the name and address of, and the number of units held
by, every unitholder of your trust. Such books and records shall be open to
inspection by any unitholder at all reasonable times during usual business
hours. The trustee shall make such annual or other reports as may from time to
time be required under any applicable state or federal statute, rule or
regulation. The trustee shall keep a certified copy or duplicate original of
the trust agreement on file in its office available for inspection at all
reasonable times during usual business hours by any unitholder, together with a
current list of the securities held in each trust. Pursuant to the trust
agreement, the trustee may employ one or more agents for the purpose of custody
and safeguarding of securities comprising your trust.

Under the trust agreement, the trustee or any successor trustee may resign
and be discharged of your trust created by the trust agreement by executing an
instrument in writing and filing the same with the sponsor.

The trustee or successor trustee must mail a copy of the notice of
resignation to all unitholders then of record, not less than sixty days before
the date specified in such notice when such resignation is to take effect. The
sponsor upon receiving notice of such resignation is obligated to appoint a
successor trustee promptly. If, upon such resignation, no successor trustee has
been appointed and has accepted the appointment within thirty days after
notification, the retiring trustee may apply to a court of competent
jurisdiction for the appointment of a successor. In case at any time the
trustee shall not meet the requirements set forth in the trust agreement, or
shall become incapable of acting, or if a court having jurisdiction in the
premises shall enter a decree or order for relief in respect of the trustee in
an involuntary case, or the trustee shall commence a voluntary case, under any
applicable bankruptcy, insolvency or other similar law

-13-

now or hereafter in effect, or any receiver, liquidator, assignee, custodian,
trustee, sequestrator (or similar official) for the trustee or for any
substantial part of its property shall be appointed, or the trustee shall
generally fail to pay its debts as they become due, or shall fail to meet such
written standards for the trustee's performance as shall be established from
time to time by the sponsor, or if the sponsor determines in good faith that
there has occurred either (1) a material deterioration in the creditworthiness
of the trustee or (2) one or more grossly negligent acts on the part of the
trustee with respect to your trust, the sponsor, upon sixty days' prior written
notice, may remove the trustee and appoint a successor trustee by written
instrument, in duplicate, one copy of which shall be delivered to the trustee so
removed and one copy to the successor trustee. Notice of such removal and
appointment shall be mailed to each unitholder by the sponsor. Upon execution
of a written acceptance of such appointment by such successor trustee, all the
rights, powers, duties and obligations of the original trustee shall vest in the
successor. The trustee must be a corporation organized under the laws of the
United States, or any state thereof, be authorized under such laws to exercise
trust powers and have at all times an aggregate capital, surplus and undivided
profits of not less than $5,000,000.

THE SPONSOR. The sponsor of your trust is Advisors Asset Management, Inc.
acting through its unit investment trust division. The sponsor is a broker-
dealer specializing in providing services to broker-dealers, registered
representatives, investment advisers and other financial professionals. The
sponsor's headquarters are located at 18925 Base Camp Road, Monument, Colorado
80132. You can contact the unit investment trust division at 8100 East 22nd
Street North, Building 800, Suite 102, Wichita, Kansas 67226 or by using the
contacts listed on the back cover of the prospectus. The sponsor is a registered
broker-dealer and investment adviser and a member of the Financial Industry
Regulatory Authority, Inc. (FINRA) and the Securities Investor Protection
Corporation (SIPC), and a registrant of the Municipal Securities Rulemaking
Board (MSRB).

The sponsor may resign by delivering written notice to the trustee.If at
any time the sponsor resigns or shall fail to perform any of its duties under
the trust agreement or shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or shall have its affairs taken over by public
authorities, then the trustee may (a) appoint a successor sponsor at rates of
compensation deemed by the trustee to be reasonable and not exceeding such
reasonable amounts as may be prescribed by the Securities and Exchange
Commission, (b) terminate the trust agreement and liquidate any trust as
provided therein, or (c) continue to act as trustee without terminating the
trust agreement. Notice of any resignation or appointment of a successor
sponsor will be delivered by the trustee to each unitholder.

THE EVALUATOR AND SUPERVISOR. Advisors Asset Management, Inc., the
sponsor, also serves as evaluator and supervisor. The evaluator and supervisor
may resign or be removed by the sponsor and trustee in which event the sponsor
or trustee is to use its best efforts to appoint a satisfactory successor. Such
resignation or removal shall become effective upon acceptance of appointment by
the successor evaluator. If upon resignation of the evaluator no successor has
accepted appointment within thirty days after notice of resignation, the
evaluator may apply to a court of competent jurisdiction for the appointment of
a successor. Notice of such resignation or removal and appointment shall be
delivered by the trustee to each unitholder.

-14-

LIMITATIONS ON LIABILITY. The sponsor, evaluator, and supervisor are
liable for the performance of their obligations arising from their
responsibilities under the trust agreement but will be under no liability to any
trust or unitholders for taking any action or refraining from any action in good
faith pursuant to the trust agreement or for errors in judgment, or for
depreciation or loss incurred by reason of the purchase or sale of securities,
provided, however, that such parties will not be protected against any liability
to which they would otherwise be subjected by reason of their own willful
misfeasance, bad faith or gross negligence in the performance of their duties or
its reckless disregard for their duties under the trust agreement. Each trust
will indemnify, defend and hold harmless each of the sponsor, supervisor and
evaluator from and against any loss, liability or expense incurred in acting in
such capacity (including the cost and expenses of the defense against such loss,
liability or expense) other than by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties under the applicable trust agreement.
Such parties are not under any obligation to appear in, prosecute or defend any
legal action which in their opinion may involve them in any expense or
liability. The trustee will be indemnified by each trust and held harmless
against any loss or liability accruing to it without gross negligence, bad faith
or willful misconduct on its part, arising out of or in connection with the
acceptance or administration of the trust, including the costs and expenses
(including counsel fees) of defending itself against any claim of liability in
the premises.

The trust agreement provides that the trustee shall be under no liability
for any action taken in good faith in reliance upon prima facie properly
executed documents or for the disposition of moneys, securities or certificates
except by reason of its own gross negligence, bad faith or willful misconduct,
or its reckless disregard for its duties under the trust agreement, nor shall
the trustee be liable or responsible in any way for depreciation or loss
incurred by reason of the sale by the trustee of any securities. In the event
that the sponsor shall fail to act, the trustee may act and shall not be liable
for any such action taken by it in good faith. The trustee shall not be
personally liable for any taxes or other governmental charges imposed upon or in
respect of the securities or upon the interest thereof. In addition, the trust
agreement contains other customary provisions limiting the liability of the
trustee.

EXPENSES OF THE TRUST. The sponsor may receive a fee from your trust for
creating and developing your trust, including determining your trust's
objectives, policies, composition and size, selecting service providers and
information services and for providing other similar administrative and
ministerial functions. The amount of this "creation and development fee" is set
forth in the prospectus. The trustee will deduct this amount from your trust's
assets as of the close of the initial offering period. No portion of this fee is
applied to the payment of distribution expenses or as compensation for sales
efforts. This fee will not be deducted from proceeds received upon a repurchase,
redemption or exchange of units before the close of the initial public offering
period.

The trustee receives for its services that fee set forth in the prospectus.
The trustee's fee which is calculated and paid monthly is based on the total
number of units of the related trust outstanding as of January 1 for any annual
period, except during the initial offering period the fee will be based on the
units outstanding at the end of each month. The trustee benefits to the extent
there are funds for future distributions, payment of expenses and redemptions in
the

-15-

Capital and Income Accounts since these Accounts are non-interest bearing and
the amounts earned by the trustee are retained by the trustee. Part of the
trustee's compensation for its services to your trust is expected to result from
the use of these funds.

The supervisor will charge your trust a surveillance fee for services
performed for your trust in an amount not to exceed that amount set forth in the
prospectus but in no event will such compensation, when combined with all
compensation received from other unit investment trusts for which the sponsor
both acts as sponsor and provides portfolio surveillance, exceed the aggregate
cost to the sponsor of providing such services. Such fee shall be based on the
total number of units of the related trust outstanding as of January 1 for any
annual period, except during the initial offering period the fee will be based
on the units outstanding at the end of each month.

For evaluation of the securities in your trust, the evaluator shall receive
an evaluation fee in an amount not to exceed that amount set forth in the
prospectus but in no event will such compensation, when combined with all
compensation from other unit investment trusts for which the sponsor acts as
sponsor and provides evaluation services, exceed the aggregate cost of providing
such services. Such fee shall be based on the total number of units of the
related trust outstanding as of January 1 for any annual period, except during
the initial offering period the fee will be based on the units outstanding at
the end of each month.

For providing bookkeeping and administrative services to your trust, the
sponsor shall receive an administration fee in an amount not to exceed that
amount set forth in the prospectus but in no event will such compensation, when
combined with all compensation from other unit investment trusts for which the
sponsor acts as sponsor and provides bookkeeping and administrative services,
exceed the aggregate cost of providing such services. Such fee shall be based
on the total number of units of the related trust outstanding as of January 1
for any annual period, except during the initial offering period the fee will be
based on the units outstanding at the end of each month.

The trustee's fee, sponsor's fee for providing bookkeeping and
administrative services to your trust, supervisor's fee and evaluator's fee are
deducted from the Income Account of the related trust to the extent funds are
available and then from the Capital Account. Each such fee may be increased
without approval of unitholders by amounts not exceeding a proportionate
increase in the Consumer Price Index or any equivalent index substituted
therefor.

The following additional charges are or may be incurred by your trust in
addition to any other fees, expenses or charges described in the prospectus:
(a) fees for the trustee's extraordinary services; (b) expenses of the trustee
(including legal and auditing expenses and reimbursement of the cost of advances
to your trust for payment of expenses and distributions, but not including any
fees and expenses charged by an agent for custody and safeguarding of
securities) and of counsel, if any; (c) various governmental charges;
(d) expenses and costs of any action taken by the trustee to protect your trust
or the rights and interests of the unitholders; (e) indemnification of the
trustee for any loss or liability accruing to it without gross negligence, bad
faith or willful misconduct on its part arising out of or in connection with the
acceptance or administration of your trust; (f) indemnification of the sponsor
for any loss, liability or expense

-16-

incurred in acting in that capacity other than by reason of willful misfeasance,
bad faith or gross negligence in the performance of its duties or its reckless
disregard of its obligations and duties under the trust agreement; (g)
indemnification of the supervisor for any loss, liability or expense incurred in
acting as supervisor of the trust other than by reason of willful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of
its reckless disregard of its obligations and duties under the trust agreement;
(h) indemnification of the evaluator for any loss, liability or expense incurred
in acting as evaluator of the trust other than by reason of willful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of
its reckless disregard of its obligations and duties under the trust agreement;
(i) expenditures incurred in contacting unitholders upon termination of your
trust; and (j) license fees for the right to use trademarks and trade names,
intellectual property rights or for the use of databases and research owned by
third party licensors. The sponsor is authorized to obtain from Mutual Fund
Quotation Service (or similar service operated by The Nasdaq Stock Market, Inc.
or its successor) a unit investment trust ticker symbol for each trust and to
contract for the dissemination of the unit prices through that service. A trust
will bear any cost or expense incurred in connection with the obtaining of the
ticker symbol and the dissemination of unit prices. A trust may pay the costs
of updating its registration statement each year. All fees and expensesare
payable out of your trust and, when owing to the trustee, are secured by a lien
on your trust. If the balances in the Income and Capital Accounts are
insufficient to provide for amounts payable by your trust, the trustee has the
power to sell securities to pay such amounts. These sales may result in capital
gains or losses to unitholders.

PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION

When your trust sells securities, the composition and diversity of the
securities in your trust may be altered. In order to obtain the best price for
your trust, it may be necessary for the sponsor to specify minimum amounts in
which blocks of securities are to be sold. In effecting purchases and sales of
your trust's portfolio securities, the sponsor may direct that orders be placed
with and brokerage commissions be paid to brokers, including brokers which may
be affiliated with your trust, the sponsor or dealers participating in the
offering of units.

PURCHASE, REDEMPTION AND PRICING OF UNITS

PUBLIC OFFERING PRICE. Units of your trust are offered at the public
offering price thereof. The public offering price per unit is equal to the net
asset value per unit plus organization costs plus the applicable sales fee
referred to in the prospectus. The initial sales fee is equal to the difference
between the maximum sales fee and the sum of the remaining deferred sales fee
and the total creation and development fee. The sales fee as a percentage of
the public offering price and the net amount invested is set forth in the
prospectus. The deferred sales fee is a fixed dollar amount and will be
collected in installments as described in the prospectus. The creation and
development fee is a fixed dollar amount and will be collected at the end of the
initial offering period as described in the prospectus. Units purchased after
the initial deferred sales fee payment will be subject to the remaining deferred
sales fee payments. Units sold or redeemed prior to such time as the entire
applicable deferred sales fee has been collected will be assessed the remaining
deferred sales fee at the time of such sale or redemption. Units sold or
redeemed prior

-17-

to such time as the entire applicable creation and development fee has been
collected will not be assessed the remaining creation and development fee at the
time of such sale or redemption. During the initial offering period, a portion
of the public offering price includes an amount of securities to pay for all or
a portion of the costs incurred in establishing your trust. These costs include
the cost of preparing the registration statement, the trust indenture and other
closing documents, registering units with the Securities and Exchange Commission
and states, the initial audit of your trust's portfolio, legal fees and the
initial fees and expenses of the trustee. These costs will be deducted from
your trust as of the end of the initial offering period or after six months, if
earlier. Certain broker-dealers may charge a transaction fee for processing unit
purchases.

As indicated above, the initial public offering price of the units was
established by dividing the aggregate underlying value of the securities by the
number of units outstanding. Such price determination as of the opening of
business on the date your trust was created was made on the basis of an
evaluation of the securities in your trust prepared by the evaluator. After the
opening of business on this date, the evaluator will appraise or cause to be
appraised daily the value of the underlying securities as of the close of
regular trading on the New York Stock Exchange on days the New York Stock
Exchange is open and will adjust the public offering price of the units
commensurate with such valuation. Such public offering price will be effective
for all orders received at or prior to the close of regular trading on the New
York Stock Exchange on each such day as discussed in the prospectus. Orders
received by the trustee, sponsor or authorized financial professionals for
purchases, sales or redemptions after that time, or on a day when the New York
Stock Exchange is closed, will be held until the next determination of price as
discussed in the prospectus.

Had units of your trust been available for sale at the close of business on
the business day before the inception date of your trust, the public offering
price would have been as shown under "Essential Information" in the prospectus.
The public offering price per unit of your trust on the date of the prospectus
or on any subsequent date will vary from the amount stated under "Essential
Information" in the prospectus in accordance with fluctuations in the prices of
the underlying securities. Net asset value per unit is determined by dividing
the value of your trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of units outstanding. The portfolio securities
are valued by the evaluator as follows: If the security is listed on a national
securities exchange, the evaluation will generally be based on the last sale
price on the exchange (unless the evaluator deems the price inappropriate as a
basis for evaluation). If the security is not so listed or, if so listed and
the principal market for the security is other than on the exchange, the
evaluation will generally be made by the evaluator in good faith based on an
appraisal of the fair value of the securities using recognized pricing methods.

The foregoing evaluations and computations shall be made as of the close of
regular trading on the New York Stock Exchange, on each business day commencing
with your trust's inception date of the securities, effective for all sales made
during the preceding 24-hour period.

Although payment is normally made three business days following the order
for purchase, payments may be made prior thereto. A person will become the
owner of units on the date of settlement provided payment has been received.
Cash, if any, made available to the sponsor prior

-18-

to the date of settlement for the purchase of units may be used in the sponsor's
business and may be deemed to be a benefit to the sponsor, subject to the
limitations of the Securities Exchange Act of 1934.

PUBLIC DISTRIBUTION OF UNITS. The sponsor intends to qualify the units for
sale in a number of states. Units will be sold through dealers who are members
of the National Association of Securities Dealers, Inc. and through others.
Sales may be made to or through dealers at prices which represent discounts from
the public offering price as set forth in the prospectus. Certain commercial
banks may be making units available to their customers on an agency basis. The
sponsor reserves the right to change the discounts from time to time.

We currently provide, at our own expense and out of our own profits,
additional compensation and benefits to broker-dealers who sell units of this
trust and our other products. This compensation is intended to result in
additional sales of our products and/or compensate broker-dealers and financial
advisors for past sales. A number of factors are considered in determining
whether to pay these additional amounts. Such factors may include, but are not
limited to, the level or type of services provided by the intermediary, the
level or expected level of sales of our products by the intermediary or its
agents, the placing of our products on a preferred or recommended product list
and access to an intermediary's personnel. We may make these payments for
marketing, promotional or related expenses, including, but not limited to,
expenses of entertaining retail customers and financial advisors, advertising,
sponsorship of events or seminars, obtaining information about the breakdown of
unit sales among an intermediary's representations or offices, obtaining shelf
space in broker-dealer firms and similar activities designed to promote the sale
of our products. We make such payments to a substantial majority of
intermediaries that sell our products. We may also make certain payments to, or
on behalf of, intermediaries to defray a portion of their costs incurred for the
purpose of facilitating unit sales, such as the costs of developing or
purchasing trading systems to process unit trades. Payments of such additional
compensation described in this paragraph and the volume concessions described
above, some of which may be characterized as "revenue sharing," may create an
incentive for financial intermediaries and their agents to sell or recommend our
products, including this trust, over other products. These arrangements will not
change the price you pay for your units. The sponsor reserves the right to
reject, in whole or in part, any order for the purchase of units.

The sponsor reserves the right to reject, in whole or in part, any order
for the purchase of units.

PROFITS OF SPONSOR. The sponsor will receive gross sales fees equal to the
percentage of the offering price of the units of such trusts stated in the
prospectus and will pay a portion of such sales fees to dealers and agents. In
addition, the sponsor may realize a profit or a loss resulting from the
difference between the purchase prices of the securities to the sponsor and the
cost of such securities to your trust. The sponsor may also realize profits or
losses with respect to securities deposited in your trust which were acquired
from underwriting syndicates of which the sponsor was a member. An underwriter
or underwriting syndicate purchases securities from the issuer on a negotiated
or competitive bid basis, as principal, with the motive of marketing such
securities to investors at a profit. The sponsor may realize additional profits
or losses during the

-19-

initial offering period on unsold units as a result of changes in the daily
evaluation of the securities in your trust.

MARKET FOR UNITS. After the initial offering period, while not obligated
to do so, the sponsor may, subject to change at any time, maintain a market for
units of your trust offered hereby and to continuously offer to purchase said
units at the net asset value determined by the evaluator, provided that the
repurchase price will not be reduced by any remaining creation and development
fee or organization costs during the initial offering period. While the sponsor
may repurchase units from time to time, it does not currently intend to maintain
an active secondary market for units. Unitholders who wish to dispose of their
units should inquire of their broker as to current market prices in order to
determine whether there is in existence any price in excess of the redemption
price and, if so, the amount thereof. Unitholders who sell or redeem units
prior to such time as the entire deferred sales fee on such units has been
collected will be assessed the amount of the remaining deferred sales fee at the
time of such sale or redemption. Unitholders who sell or redeem units prior to
such time as the entire creation and development fee on such units has been
collected will not be assessed the amount of the remaining creation and
development fee at the time of such sale or redemption. The offering price of
any units resold by the sponsor will be in accord with that described in the
currently effective prospectus describing such units. Any profit or loss
resulting from the resale of such units will belong to the sponsor. If the
sponsor decides to maintain a secondary market, it may suspend or discontinue
purchases of units of your trust if the supply of units exceeds demand, or for
other business reasons.

REDEMPTION. A unitholder who does not dispose of units in the secondary
market described above may cause units to be redeemed by the trustee by making a
written request to the trustee at its unit investment trust division office.
Unitholders must sign the request exactly as their names appear on the records
of the trustee. Additional documentation may be requested, and a signature
guarantee is always required, from corporations, executors, administrators,
trustees, guardians or associations. The signatures must be guaranteed by a
participant in the Securities Transfer Agents Medallion Program ("STAMP") or
such other signature guaranty program in addition to, or in substitution for,
STAMP, as may be accepted by the trustee.

Redemption shall be made by the trustee no later than the seventh day
following the day on which a tender for redemption is received (the "Redemption
Date") by payment of cash equivalent to the redemption price, determined as set
forth below under "Computation of Redemption Price," as of the close of regular
trading on the New York Stock Exchange next following such tender, multiplied by
the number of units being redeemed. Any units redeemed shall be canceled and
any undivided fractional interest in the related trust extinguished. The price
received upon redemption might be more or less than the amount paid by the
unitholder depending on the value of the securities in your trust at the time of
redemption. Unitholders who sell or redeem units prior to such time as the
entire deferred sales fee on such units has been collected will be assessed the
amount of the remaining deferred sales fee at the time of such sale or
redemption. Unitholders who sell or redeem units prior to such time as the
entire creation and development fee on such units has been collected will not be
assessed the amount of the remaining creation and development fee at the time of
such sale or redemption. Certain broker-dealers may charge a transaction fee
for processing redemption requests.

-20-

Under regulations issued by the Internal Revenue Service, the trustee is
required to withhold a specified percentage of the principal amount of a unit
redemption if the trustee has not been furnished the redeeming unitholder's tax
identification number in the manner required by such regulations. Any amount so
withheld is transmitted to the Internal Revenue Service and may be recovered by
the unitholder only when filing a tax return. Under normal circumstances, the
trustee obtains the unitholder's tax identification number from the selling
broker. However, any time a unitholder elects to tender units for redemption,
such unitholder should make sure that the trustee has been provided a certified
tax identification number in order to avoid this possible "back-up withholding."
In the event the trustee has not been previously provided such number, one must
be provided at the time redemption is requested. Any amounts paid on redemption
representing interest shall be withdrawn from the Income Account of your trust
to the extent that funds are available for such purpose. All other amounts paid
on redemption shall be withdrawn from the Capital Account for your trust.

Unitholders tendering units for redemption may request a distribution in
kind (a "Distribution In Kind") from the trustee in lieu of cash redemption of
an amount and value of securities per unit equal to the redemption price per
unit as determined as of the evaluation time next following the tender, provided
that the tendering unitholder meets the requirements stated in the prospectus
and the unitholder has elected to redeem at least thirty days prior to the
termination of your trust. If the unitholder meets these requirements, a
Distribution In Kind will be made by the trustee through the distribution of
each of the securities of your trust in book entry form to the account of the
unitholder's bank or broker-dealer at Depository Trust Company. The tendering
unitholder shall be entitled to receive whole shares of each of the securities
comprising the portfolio of your trust and cash from the Capital Account equal
to the fractional shares to which the tendering unitholder is entitled. The
trustee shall make any adjustments necessary to reflect differences between the
redemption price of the units and the value of the securities distributed in
kind as of the date of tender. If funds in the Capital Account are insufficient
to cover the required cash distribution to the tendering unitholder, the trustee
may sell securities. The in kind redemption option may be terminated by the
sponsor at any time.

The trustee is empowered to sell securities in order to make funds
available for the redemption of units. To the extent that securities are sold
or redeemed in-kind, the size of your trust will be, and the diversity of your
trust may be, reduced but each remaining unit will continue to represent
approximately the same proportional interest in each security. Sales may be
required at a time when securities would not otherwise be sold and may result in
lower prices than might otherwise be realized. The price received upon
redemption may be more or less than the amount paid by the unitholder depending
on the value of the securities in the portfolio at the time of redemption.

The trustee is irrevocably authorized in its discretion, if the sponsor
does not elect to purchase any unit tendered for redemption, in lieu of
redeeming such units, to sell such units in the over-the-counter market for the
account of tendering unitholders at prices which will return to the unitholders
amounts in cash, net after brokerage commissions, transfer taxes and other
charges, equal to or in excess of the redemption price for such units. In the
event of any such sale, the trustee shall pay the net proceeds thereof to the
unitholders on the day they would otherwise be entitled to receive payment of
the redemption price.

-21-

The right of redemption may be suspended and payment postponed (1) for any
period during which the New York Stock Exchange is closed, other than customary
weekend and holiday closings, or during which (as determined by the Securities
and Exchange Commission) trading on the New York Stock Exchange is restricted;
(2) for any period during which an emergency exists as a result of which
disposal by the trustee of securities is not reasonably practicable or it is not
reasonably practicable to fairly determine the value of the underlying
securities in accordance with the trust agreement; or (3) for such other period
as the Securities and Exchange Commission may by order permit. The trustee is
not liable to any person in any way for any loss or damage which may result from
any such suspension or postponement.

COMPUTATION OF REDEMPTION PRICE. The redemption price for units of each
trust is computed by the evaluator as of the evaluation time stated in the
prospectus next occurring after the tendering of a unit for redemption and on
any other business day desired by it, by:

A. Adding: (1) the cash on hand in your trust other than cash deposited in
your trust to purchase securities not applied to the purchase of such
securities and (2) the aggregate value of each issue of the securities held
in your trust as determined by the evaluator as described above;

B. Deducting therefrom (1) amounts representing any applicable taxes or
governmental charges payable out of your trust and for which no deductions
have been previously made for the purpose of additions to the Reserve
Account; (2) an amount representing estimated accrued expenses, including
but not limited to fees and expenses of the trustee (including legal and
auditing fees), the evaluator, the sponsor and counsel, if any; (3) cash
held for distribution to unitholders of record as of the business day prior
to the evaluation being made; and (4) other liabilities incurred by your
trust, provided that the redemption price will not be reduced by any
remaining creation and development fee or organization costs during the
initial offering period; and

C. Finally dividing the results of such computation by the number of units of
your trust outstanding as of the date thereof.

RETIREMENT PLANS. Your trust may be suited for purchase by Individual
Retirement Accounts, Keogh Plans, pension funds and other qualified retirement
plans. Generally, capital gains and income received under each of the foregoing
plans are deferred from Federal taxation. All distributions from such plans are
generally treated as ordinary income but may, in some cases, be eligible for
special income averaging or tax-deferred rollover treatment. Investors
considering participation in any such plan should review specific tax laws
related thereto and should consult their attorneys or tax advisers with respect
to the establishment and maintenance of any such plan. Such plans are offered
by brokerage firms and other financial institutions. Your trust will lower the
minimum investment requirement for IRA accounts. Fees and charges with respect
to such plans may vary.

OWNERSHIP OF UNITS. Ownership of units will not be evidenced by
certificates. Units may be purchased in denominations of one unit or any
multiple thereof, subject to the minimum investment requirement. Fractions of
units, if any, will be computed to three decimal places.
