Dividend Sustainability Portfolio

Investment Objective. The Portfolio\nseeks above average capital appreciation.

Principal Investment Strategy. The\nPortfolio seeks to achieve its objective by investing in a portfolio of common stocks of companies derived from the S&P 500 Dividend\nAristocrats Index. The S&P 500 Dividend Aristocrats Index consists of stocks of those companies contained in the S&P 500 Index\nthat have followed a policy of consistently increasing dividends every year for at least 25 years, which Invesco Capital Markets, Inc.,\nthe Sponsor, refers to as “dividend sustainability” companies. The Sponsor selected the stocks for the Portfolio from among\nthe S&P 500 Dividend Aristocrats Index component list as most recently made available to the Sponsor prior to the Initial Date of\nDeposit. As of the Initial Date of Deposit, all of the Portfolio’s investments are in securities of “dividend sustainability”\ncompanies.

The Portfolio will consist of companies selected\nby the Sponsor from a selection universe of companies included in the S&P 500 Dividend Aristocrats Index; the companies, if rated,\nmust have a domestic S&P Global Quality Rank of B or better and, if rated, an S&P Global Issuer Credit Rating of BBB or better.

Beginning with the S&P 500 Dividend Aristocrats\nIndex, the Sponsor selected the composition of the Portfolio by: (1) eliminating companies with a share price below $5 at the time of\nselection; (2) eliminating companies, if rated, with an S&P Global Quality Ranking below B and, if rated, with an S&P Global Issuer\nCredit Rating below BBB (companies which do not have a domestic S&P Global Quality Rank or an S&P Global Issuer Credit Rating\nmay be included); and (3) applying a fundamental, qualitative selection process focusing on factors including, but not limited to:

•

Valuation – Companies whose current valuations appear attractive relative to long-term trends;

•

Growth – Companies with a history of and prospects for above average growth of sales and earnings;

•

Cash Flow Generation – Companies with a history of generating attractive operating and free cash flows in order to facilitate\ncurrent and future dividends;

•

Balance Sheet – Companies displaying balance sheet strength evidenced by a history of achieving strong financial results and\nmaking disciplined capital management decisions; and

•

Returns – Companies with a history of above average returns on invested capital.

Of course, we cannot guarantee that your Portfolio\nwill achieve its objective. The value of your Units may fall below the price you paid for the Units. You should read the “Risk Factors”\nsection before you invest.

The Portfolio is designed as part of a long-term\ninvestment strategy. The Sponsor may offer a subsequent series of the portfolio when the current Portfolio terminates. As a result, you\nmay achieve more consistent overall results by following the strategy through reinvestment of your proceeds over several years if subsequent\nseries are available. Repeatedly rolling over an investment in a unit investment trust may differ from long-term investments in other\ninvestment products when considering the sales charges, fees, expenses and tax consequences attributable to a Unitholder. For more information\nsee “Rights of Unitholders--Rollover”.

Principal Risks. As with all\ninvestments, you can lose money by investing in this Portfolio. The Portfolio also might not perform as well as you expect. This can happen\nfor 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\nmay 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\nmay occur at any point in time, including during the initial offering period.

•

You could experience dilution of your investment if the size of the Portfolio is increased as Units are sold. There is no assurance\nthat your investment will maintain its proportionate share in the Portfolio’s profits and losses.

•

The Portfolio does not replicate all of the components of the S&P 500 Dividend Aristocrats Index or its component weightings\nand the stocks in the Portfolio will not change if the index components, or their weightings within the index, change. The performance\nof the Portfolio will not correspond with the S&P 500 Dividend Aristocrats Index for this reason and because the Portfolio incurs\na sales charge and expenses. The Portfolio is not intended to replicate the performance of the index.

•

The Portfolio is concentrated in securities issued by companies in the consumer discretionary and consumer staples sectors. As\nfurther discussed in “Risk Factors -Sector Risks,” companies that manufacture and distribute consumer products face risks\nsuch as intense competition, substantial government regulation, increased impact from an economic recession, and changes in consumer spending\ntrends. Negative developments in these sectors will affect the value of your investment more than would be the case in a more diversified\ninvestment.

•

We do not actively manage the Portfolio. Except in limited circumstances, the Portfolio will hold, and may continue to buy,\nshares of the same securities even if their market value declines.

Fee Table

The amounts below are estimates of the direct\nand indirect expenses that you may incur based on a $10 Public Offering Price per Unit. Actual expenses may vary.


	As a % of
	Public	Amount
	Offering	Per 100
Sales Charge	Price	Units
Initial sales charge	0.000%	$ 0.000
Deferred sales charge	2.250	22.500
Creation and development fee	0.500	5.000
Maximum sales charge	2.750%	$27.500

	As a %	Amount
	of Net	Per 100
	Assets	Units
Estimated\n Organization Costs	0.190%	$1.848
Estimated\n Annual Expenses
Trustee’s\n fee and operating expenses	0.200%	$1.940
Supervisory,\n bookkeeping
and\n administrative fees	0.057	0.550
Total	0.257%	$2.490*

Example

This example helps you compare the cost of\nthe Portfolio with other unit trusts and mutual funds. In the example we assume that the expenses do not change and that the Portfolio’s\nannual return is 5%. Your actual returns and expenses will vary. This example also assumes that you continue to follow the Portfolio strategy\nand roll your investment, including all distributions, into a new trust every two years subject to a sales charge of 2.75%. Based on these\nassumptions, you would pay the following expenses for every $10,000 you invest in the Portfolio:

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n


1\n year	$\n 318
3\n years	683
5\n years	1,071
10\n years	1,956

_________________

The estimated annual expenses are based upon the estimated trust size for the Portfolio determined as of the initial date of deposit.\nBecause certain of the operating expenses are fixed amounts, if the Portfolio does not reach the estimated size, or if the value of the\nPortfolio or number of outstanding units decline over the life of the trust, or if the actual amount of the operating expenses exceeds\nthe estimated amounts, the actual amount of the operating expenses per 100 units would exceed the estimated amounts. In some cases, the\nactual amount of operating expenses may substantially differ from the amounts reflected above.

The maximum sales charge is 2.75% of the\nPublic Offering Price per Unit. There is no initial sales charge at a Public Offering Price of $10 or less. If the Public Offering Price\nexceeds $10 per Unit, the initial sales charge is the difference between the total sales charge (maximum of 2.75% of the Public Offering\nPrice) and the sum of the remaining deferred sales charge and the creation and development fee. The deferred sales charge is fixed at\n$0.225 per Unit and accrues daily from March 10, 2027 through August 9, 2027. Your Portfolio pays a proportionate amount of this charge\non the 10th day of each month beginning in the accrual period until paid in full. The combination of the initial and deferred sales charges\ncomprises the “transactional sales charge”. The creation and development fee is fixed at $0.05 per Unit and is paid at the\nearlier of the end of the initial offering period (anticipated to be three months) or six months following the Initial Date of Deposit.\nFor more detail, see “Public Offering Price - General.”

As of close of business day prior to Initial Date of Deposit. Dividend payments are not assured and therefore the amount of future\ndividend income to your Portfolio is uncertain. The actual distributions you receive will vary from this per Unit amount due to changes\nin the Portfolio’s fees and expenses, in actual income received by the Portfolio, currency fluctuations and with changes in the\nPortfolio such as the acquisition or liquidation of securities. The Historical 12 Month Distributions per Unit amount shown is based upon\nthe weighted average of the actual distributions paid by the securities included in your Portfolio over the 12 Months preceding the Initial\nDate of Deposit, divided by the Portfolio's initial public offering price of $10 per unit, and reduced by the anticipated per Unit fees\nand expenses which will be incurred when investing in your Portfolio. See “Rights of Unitholders - Historical 12 Month Distributions.”

The Trustee will make distributions of income and capital on each Distribution Date to Unitholders of record on the preceding Record\nDate, provided that the total cash held for distribution equals at least $0.01 per Unit on such Record Date. Undistributed income and\ncapital will be distributed on the next Distribution Date on which the total cash held for distribution equals at least $0.01 per Unit.

International Dividend Sustainability Portfolio

Investment Objective. The Portfolio\nseeks above average capital appreciation.

Principal Investment Strategy. The\nPortfolio seeks to achieve its objective by investing in a portfolio of common stocks and American Depositary Receipts (“ADRs”)\nof foreign companies with a history of increasing dividend distributions, which Invesco Capital Markets, Inc., the Sponsor, refers to\nas international “dividend sustainability” companies. The Sponsor only considered companies with an S&P Global Issuer\nCredit Rating of BBB- or higher and a minimum share price of $5 (USD) at the time of selection. Companies considered for inclusion in\nthe Portfolio must have demonstrated consistent dividend per share growth over the last 5 years. As of the Initial Date of Deposit, all\nof the Portfolio’s investments are in securities of international “dividend sustainability” companies.

Beginning with a universe of foreign companies\nthat trade on a U.S. stock exchange, either directly or through an ADR, the Sponsor selected the composition of the Portfolio by: (1)\neliminating companies with a share price below $5 at the time of selection; (2) eliminating companies with an S&P Global Issuer Credit\nRating below BBB-; (3) eliminating companies that have not demonstrated consistent dividend per share growth over the last 5 years; and\n(4) applying a fundamental, qualitative selection process focusing on factors including, but not limited to:

•

Valuation – Companies whose current valuations appear attractive relative to long-term trends;

•

Growth – Companies with a history of and prospects for above average growth of sales and earnings;

•

Cash Flow Generation – Companies with a history of generating attractive operating and free cash flow in order to facilitate\ncurrent and future dividends;

•

Balance Sheet – Companies displaying balance sheet strength evidenced by a history of achieving strong financial results and\nmaking disciplined capital management decisions; and

•

Returns – Companies with a history of above average returns on invested capital.

The final Portfolio is constructed so that\nno more than 50% of the Portfolio will be invested in any one particular country and a minimum of 5 countries will be represented in the\nPortfolio at the time of selection.

•

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\nmay 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\nduring the initial offering period.

•

Stocks of foreign companies in the Portfolio present risks beyond those of U.S. issuers. These risks may include market and\npolitical factors related to the company’s foreign market, international trade conditions, less regulation, smaller or less liquid\nmarkets, increased volatility, differing accounting practices and changes in the value of foreign currencies.

•

The Portfolio is concentrated in securities issued by companies domiciled in Canada. As a result, political or economic developments\nin Canada may have a significant impact on the securities included in the Portfolio.

•

The Portfolio is concentrated in securities issued by companies domiciled in Europe. As a result, political or economic developments\nin Europe may have a significant impact on the securities included in the Portfolio.

•

We do not actively manage the Portfolio. Except in limited circumstances, the Portfolio will hold, and may continue to buy,\nshares of the same securities even if their market value declines.

Invesco Capital Markets, Inc. is the Sponsor of the\nPortfolio. The Sponsor refers to companies selected through the Dividend Sustainability Strategy as “dividend sustainability”\ncompanies and those selected through the International Dividend Sustainability Strategy as international “dividend sustainability”\ncompanies. As of the Initial Date of Deposit, the Portfolio invests all of its assets in securities of “dividend sustainability”\nand international “dividend sustainability” companies.

The Dividend Sustainability Strategy selects\ncommon stocks of companies derived from the S&P 500 Dividend Aristocrats Index. The S&P 500 Dividend Aristocrats Index consists\nof stocks of those companies contained in the S&P 500 Index that have followed a policy of consistently increasing dividends every\nyear for at least 25 years. The Sponsor selected the stocks for the Portfolio from among the S&P 500 Dividend Aristocrats Index component\nlist as most recently made available to the Sponsor prior to the Initial Date of Deposit.

•

Valuation – Companies whose current valuations appear attractive relative to long-term trends;

•

Growth – Companies with a history of and prospects for above average growth of sales and earnings;

•

Cash Flow Generation – Companies with a history of generating attractive operating and free cash flows in order to facilitate\ncurrent and future dividends;

•

Balance Sheet – Companies displaying balance sheet strength evidenced by a history of achieving strong financial results and\nmaking disciplined capital management decisions; and

•

Returns – Companies with a history of above average returns on invested capital.

The International Dividend Sustainability\nStrategy selects common stocks and American Depositary Receipts (“ADRs”) of foreign companies with a history of increasing\ndividend distributions. The Sponsor only considered companies with an S&P Global Issuer Credit Rating of BBB- or higher and a minimum\nshare price of $5 (USD) at the time of selection. Companies considered for inclusion in the Portfolio must have demonstrated consistent\ndividend per share growth over the last 5 years.

qualitative selection process focusing on factors including, but\nnot limited to:

•

Valuation – Companies whose current valuations appear attractive relative to long-term trends;

•

Growth – Companies with a history of and prospects for above average growth of sales and earnings;

•

Cash Flow Generation – Companies with a history of generating attractive operating and free cash flow in order to facilitate\ncurrent and future dividends;

•

Balance Sheet – Companies displaying balance sheet strength evidenced by a history of achieving strong financial results and\nmaking disciplined capital management decisions; and

•

Returns – Companies with a history of above average returns on invested capital.

The final Portfolio sleeve is constructed\nso that no more than 50% of the Portfolio sleeve will be invested in any one particular country and a minimum of 5 countries will be represented\nin the Portfolio sleeve at the time of selection.

•

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\nmay 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.\nThis may occur at any point in time, including during the initial offering period.

•

We do not actively manage the Portfolio. Except in limited circumstances, the Portfolio will hold, and may continue to buy,\nshares of the same securities even if their market value declines.

Notes to Portfolios

(1)

The Securities are initially represented by “regular way” contracts to purchase the Securities. A letter of credit has\nbeen deposited with the Trustee covering the funds necessary for the purchase of the Securities as of the close of business on the last\nbusiness day prior to the inception date of the Portfolio. The Sponsor has instructed the Trustee to purchase the securities on behalf\nof the Portfolio at the opening of business on the inception date of the Portfolio and are expected to settle within one business day\n(see “The Portfolios”).

(2)

The valuation of the Securities has been determined by the Evaluator as of the close of business on the last business day prior to\nthe inception date of the Portfolio. In accordance with Financial Accounting Standards Board Accounting Standards Codification 820, “Fair\nValue Measurement,” the Portfolio’s investments are classified as Level 1, which refers to securities traded in an active\nmarket.

For the Dividend Sustainability Portfolio and the Global\nDividend Sustainability Portfolio, “+” indicates that the security was issued by a foreign company.

REPORT OF INDEPENDENT REGISTERED PUBLIC\nACCOUNTING FIRM

To the Sponsor and Unitholders of Invesco Unit Trusts, Series\n2504:

Opinion on the Financial Statements

We have audited the accompanying statements\nof condition (including the related portfolio schedules) of Dividend Sustainability Portfolio 2026-4, International Dividend Sustainability\nPortfolio 2026-4 and Global Dividend Sustainability Portfolio 2026-4 (included in Invesco Unit Trusts, Series 2504 (the “Trust”))\nas of November 4, 2026, and the related notes (collectively referred to as the “financial statements”). In our opinion, the\nfinancial statements present fairly, in all material respects, the financial position of the Trust as of November 4, 2026, in conformity\nwith accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility\nof Invesco Capital Markets, Inc., the Sponsor. Our responsibility is to express an opinion on the Trust’s financial statements based\non our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”)\nand are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules\nand regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with\nthe standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the\nfinancial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we\nengaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding\nof internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Trust’s\ninternal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures\nto assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that\nrespond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial\nstatements. Our audits also included evaluating the accounting principles used and significant estimates made by the Sponsor, as well\nas evaluating the overall presentation of the financial statements. Our procedures included confirmation of cash or irrevocable letters\nof credit deposited for the purchase of securities as shown in the statements of condition as of November 4, 2026 by correspondence with\nThe Bank of New York Mellon, Trustee. We believe that our audits provide a reasonable basis for our opinion.

/s/ GRANT THORNTON LLP

We have served as the auditor of one or more\nof the unit investment trusts, sponsored by Invesco Capital Markets, Inc. and its predecessors, since 1976.

__________________

(1)

The value of the Securities is determined by the Evaluator on the bases set forth under “Public Offering--Unit Price”.\nThe contracts to purchase Securities are collateralized by separate irrevocable letters of credit which have been deposited with the Trustee.

(2)

A portion of the Public Offering Price represents an amount sufficient to pay for all or a portion of the costs incurred in establishing\na Portfolio. The amount of these costs are set forth in the “Fee Table”. A distribution will be made as of the earlier of\nthe close of the initial offering period (approximately three months) or six months following the Initial Date of Deposit to an account\nmaintained by the Trustee from which the organization expense obligation of the investors will be satisfied. To the extent that actual\norganization costs of a Portfolio are greater than the estimated amount, only the estimated organization costs added to the Public Offering\nPrice will be reimbursed to the Sponsor and deducted from the assets of the Portfolio.

(3)

Represents the amount of mandatory distributions from a Portfolio on the bases set forth under “Public Offering”.

(4)

The creation and development fee is payable by a Portfolio on behalf of Unitholders out of the assets of the Portfolio as of the close\nof the initial offering period. If Units are redeemed prior to the close of the initial public offering period, the fee will not be deducted\nfrom the proceeds.

(5)

The aggregate public offering price and the aggregate sales charge are computed on the bases set forth under “Public Offering”.

(6)

Assumes the maximum sales charge.

THE PORTFOLIOS

The Portfolios were created under the laws\nof the State of New York pursuant to a Trust Indenture and Trust Agreement (the “Trust Agreement”), dated the date of this\nprospectus (the “Initial Date of Deposit”), among Invesco Capital Markets, Inc., as Sponsor and Evaluator, Invesco Investment\nAdvisers LLC, as Supervisor, and The Bank of New York Mellon, as Trustee.

The Portfolios offer investors the opportunity\nto purchase Units representing proportionate interests in a portfolio of securities. Each Portfolio may be an appropriate medium for investors\nwho desire to participate in a portfolio of securities with greater diversification than they might be able to acquire individually.

On the Initial Date of Deposit, the Sponsor\ndeposited contracts to purchase Securities and an irrevocable letter of credit in the amount required for these purchases with the Trustee.\nIn exchange for these contracts the Trustee delivered to the Sponsor documentation evidencing the ownership of Units of the Portfolios.\nUnless otherwise terminated as provided in the Trust Agreement, your Portfolio will terminate on the Mandatory Termination Date and any\nremaining Securities will be liquidated or distributed by the Trustee within a reasonable time. As used in this prospectus the term “Securities”\nmeans the securities (including contracts to purchase these securities) listed in the “Portfolios” and any additional securities\ndeposited into the Portfolios.

Additional Units of your Portfolio may be\nissued at any time by depositing in the Portfolio (i) additional Securities, (ii) contracts to purchase Securities together with cash\nor irrevocable letters of credit or (iii) cash (or a letter of credit or the equivalent) with instructions to purchase additional Securities.\nAs additional Units are issued by your Portfolio, the aggregate value of the Securities will be increased and the fractional undivided\ninterest represented by each Unit may be decreased. The Sponsor may continue to make additional deposits into your Portfolio following\nthe Initial Date of Deposit provided that the additional deposits will be in amounts which will maintain, as nearly as practicable, the\nsame percentage relationship among the number of shares of each Security in the Portfolio that existed immediately prior to the subsequent\ndeposit. Investors may experience a dilution of their investments and a reduction in their anticipated income because of fluctuations\nin the prices of the Securities between the time of the deposit and the purchase of the Securities and because your Portfolio will pay\nthe associated brokerage or acquisition fees. In addition, during the initial offering of Units it may not be possible to buy a particular\nSecurity due to regulatory or trading restrictions, or corporate actions. While such limitations are in effect, additional Units would\nbe created by purchasing each of the Securities in your Portfolio that are not subject to those limitations. This would also result in\nthe dilution of the investment in any such Security not purchased and potential variances in anticipated income. Purchases and sales of\nSecurities by your Portfolio may impact the value of the Securities. This may especially be the case during the initial offering of Units,\nupon Portfolio termination and in the course of satisfying large Unit redemptions.

Each Unit of your Portfolio initially offered\nrepresents an undivided interest in the Portfolio. At the close of the New York Stock Exchange on the Initial Date of Deposit, the number\nof Units may be adjusted so that the Public Offering Price per Unit equals $10. The number of Units, fractional interest of each Unit\nin your Portfolio, and the per Unit amount of \"Historical 12 Month Distributions,\" as presented under \"Essential Information,\"\nwill increase or decrease to the extent of any adjustment. To the extent that any Units are redeemed to the Trustee or additional Units\nare issued as a result of additional Securities being deposited by the Sponsor, the fractional undivided interest in your Portfolio represented\nby each unredeemed Unit will increase or decrease accordingly, although the actual interest in your Portfolio will remain unchanged. Units\nwill remain outstanding until redeemed upon tender to the Trustee by Unitholders, which may include the Sponsor, or until the termination\nof the Trust Agreement.

Your Portfolio consists of (a) the Securities\n(including contracts for the purchase thereof) listed under the applicable “Portfolio” as may continue to be held from time\nto time in the Portfolio, (b) any additional Securities acquired and held by the Portfolio pursuant to the provisions of the Trust Agreement\nand (c) any cash held in the related Income and Capital Accounts. Neither the

A-1

Sponsor nor the Trustee shall be liable in any way for any contract\nfailure in any of the Securities.

OBJECTIVES AND SECURITIES\nSELECTION

The objective of your Portfolio is described\nin the individual Portfolio sections. There is no assurance that your Portfolio will achieve its objective.

Dividend Sustainability Portfolio and Global\nDividend Sustainability Portfolio. The Sponsor, on behalf of the Dividend Sustainability Portfolio and Global Dividend Sustainability\nPortfolio, has entered into a license agreement with S&P Opco, LLC under which the Portfolios are granted a license to use certain\ntrademarks and tradenames, to the extent the Sponsor deems appropriate and desirable under federal and state securities laws to indicate\nthe index that is a source for determining the composition of the Portfolios.

Each Portfolio is based in part on an S&P\nIndex, but is not sponsored, endorsed, marketed or promoted by S&P Dow Jones Indices LLC or its affiliates or its third party licensors,\nincluding Standard & Poor’s Financial Services LLC (“SPFS”) and Dow Jones Trademark Holdings LLC (“Dow Jones”)\n(collectively, “S&P Dow Jones Indices”). S&P® is a registered trademark of SPFS, and Dow Jones® is a registered\ntrademark of Dow Jones and have been licensed for use.

Each Portfolio is not sponsored, endorsed,\nsold or promoted by S&P Dow Jones Indices. S&P Dow Jones Indices does not make any representation or warranty, express or implied,\nto the owners of each Portfolio or any member of the public regarding the advisability of investing in securities generally or in those\nPortfolios particularly. S&P Dow Jones Indices’ only relationship to the Sponsor with respect to each Portfolio is the licensing\nof the underlying S&P Index, certain trademarks, service marks and trade names of S&P Dow Jones Indices, and the provision of\nthe calculation services. S&P Dow Jones Indices is not responsible for and has not participated in the determination of the prices\nand amount of each Portfolio or the timing of the issuance or sale of those Portfolios or in the determination or calculation of the equation\nby which those Portfolios may be converted into cash or other redemption mechanics. S&P Dow Jones Indices has no obligation or liability\nin connection with the administration, marketing or trading of each Portfolio. S&P Dow Jones Indices LLC is not an investment advisor.\nInclusion of a security within a Portfolio is not a recommendation by S&P Dow Jones Indices to buy, sell, or hold such security, nor\nis it investment advice.

S&P DOW JONES INDICES DOES NOT GUARANTEE\nTHE ADEQUACY, ACCURACY, TIMELINESS AND/OR THE COMPLETENESS OF EACH PORTFOLIO, INTELLECTUAL PROPERTY, SOFTWARE, OR ANY DATA RELATED THERETO\nOR ANY COMMUNICATION WITH RESPECT THERETO, INCLUDING, ORAL, WRITTEN, OR ELECTRONIC COMMUNICATIONS. S&P DOW JONES INDICES SHALL NOT\nBE SUBJECT TO ANY DAMAGES OR LIABILITY FOR ANY ERRORS, OMISSIONS, OR DELAYS THEREIN. S&P DOW JONES INDICES MAKES NO EXPRESS OR IMPLIED\nWARRANTIES, AND EXPRESSLY DISCLAIMS ALL WARRANTIES, OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE OR AS TO RESULTS TO\nBE OBTAINED BY THE SPONSOR, OWNERS OF EACH PORTFOLIO, OR ANY OTHER PERSON OR ENTITY FROM THE USE OF THOSE PORTFOLIOS, INTELLECTUAL PROPERTY,\nSOFTWARE, OR WITH RESPECT TO ANY DATA RELATED THERETO. WITHOUT LIMITING ANY OF THE FOREGOING, IN NO EVENT WHATSOEVER SHALL S&P DOW\nJONES INDICES BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO, LOSS\nOF PROFITS, TRADING LOSSES, LOST TIME, OR GOODWILL, EVEN IF THEY HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, WHETHER IN CONTRACT,\nTORT, STRICT LIABILITY, OR OTHERWISE.

The Sponsor does not manage the Portfolios.\nYou should note that the Sponsor applied the selection criteria to the Securities for inclusion in your Portfolio prior to the Initial\nDate of Deposit. After this time, the Securities may no longer meet the selection criteria. Should a Security no longer meet the selection\ncriteria, we will generally not remove the Security from its Portfolio. In offering the Units to the public, neither the Sponsor nor any\nbroker-dealers are recommending any of the individual Securities but

A-2

rather the entire pool of Securities in a Portfolio, taken as a\nwhole, which are represented by the Units.

RISK FACTORS

All investments involve risk. This section\ndescribes the main risks that can impact the value of the securities in your Portfolio. You should understand these risks before you invest.\nIf the value of the securities falls, the value of your Units will also fall. We cannot guarantee that your Portfolio will achieve its\nobjective or that your investment return will be positive over any period.

Market Risk. Market risk is\nthe risk that the value of the securities in your Portfolio will fluctuate. This could cause the value of your Units to fall below your\noriginal purchase price. Market value fluctuates in response to various factors. These can include changes in interest rates, inflation,\nthe financial condition of a security’s issuer, perceptions of the issuer, or ratings on a security of the issuer. The imposition\nof tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures taken in response to such actions),\nor the threat or potential of one or more such events and developments, could lead to price volatility and overall declines in the US\nand global investment markets. Additionally, certain geopolitical and other events, including environmental events and public health events\nsuch as epidemics and pandemics, may have a global impact and add to instability in world economies and markets generally. Changing economic,\npolitical or financial market conditions in one country or geographic region could adversely affect the market value of the securities\nheld by your Portfolio in a different country or geographic region due to increasingly interconnected global economies and financial markets.

Geopolitical conflicts, military actions,\nterrorism, sanctions, trade restrictions and other international events may adversely affect regional and global economies and financial\nmarkets. Such events may increase market volatility, reduce liquidity, disrupt trade and supply chains and adversely affect particular\ncountries, regions, sectors or issuers, including issuers without direct exposure to the affected areas. The duration and effects of\nsuch events are difficult to predict and may negatively affect your Portfolio’s performance and the value of an investment in your\nPortfolio.

Even though your Portfolio is supervised,\nyou should remember that we do not manage your Portfolio. Your Portfolio will not sell a security solely because the market value falls\nas is possible in a managed fund.

Dividend Payment Risk. Dividend\npayment risk is the risk that an issuer of a security is unwilling or unable to pay dividends on a security. Stocks represent ownership\ninterests in the issuers and are not obligations of the issuers. Common stockholders have a right to receive dividends only after the\ncompany has provided for payment of its creditors, bondholders and preferred stockholders. Common stocks do not assure dividend payments.\nDividends are paid only when declared by an issuer’s board of directors and the amount of any dividend may vary over time. If dividends\nreceived by your Portfolio are insufficient to cover expenses, redemptions or other Portfolio costs, it may be necessary for your Portfolio\nto sell Securities to cover such expenses, redemptions or other costs. Any such sales may result in capital gains or losses to you. See\n“Taxation”.

Index Correlation. The Dividend\nSustainability Portfolio will consist of stocks from the S&P 500 Dividend Aristocrats Index and the Global Dividend Sustainability\nPortfolio will consist, in part, of stocks from the S&P 500 Dividend Aristocrats Index. These Portfolios do not seek to replicate\nall of the components of an index or its component weightings and the stocks in either Portfolio will not change if the index components,\nor their weightings within the index, change. The performance of each Portfolio will not correspond with an index for this reason and\nbecause each Portfolio incurs a sales charge and expenses.

Foreign Stocks. Because the\nInternational Dividend Sustainability Portfolio invests exclusively in foreign stocks, and the Global Dividend Sustainability Portfolio\ninvests significantly in foreign stocks, these Portfolios may involve additional risks that differ from an investment in domestic stocks.\nThese risks include the risk of losses due to future political and economic developments, international trade conditions, foreign withholding\ntaxes and restrictions on foreign investments or exchange of

A-3

securities, foreign currency fluctuations or restriction on exchange\nor repatriation of currencies.

The political, economic and social structures\nof some foreign countries may be less stable and more volatile than those in the U.S. Investments in these countries may be subject to\nthe risks of internal and external conflicts, currency devaluations, foreign ownership limitations and tax increases. It is possible that\na government may take over the assets or operations of a company or impose restrictions on the exchange or export of currency or other\nassets. Some countries also may have different legal systems that may make it difficult for a Portfolio to vote proxies, exercise investor\nrights, and pursue legal remedies with respect to its foreign investments. Diplomatic and political developments, including rapid and\nadverse political changes, social instability, regional conflicts, terrorism and war, could affect the economies, industries, and securities\nand currency markets, and the value of a Portfolio’s investments, in non-U.S. countries. No one can predict the impact that these\nfactors could have on a Portfolio’s securities.

Certain stocks may be held in the form of\nAmerican Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), or other similar receipts. ADRs and\nGDRs represent receipts for foreign common stock deposited with a custodian (which may include the Trustee). The ADRs in your Portfolio,\nif any, trade in the U.S. in U.S. dollars and are registered with the SEC. GDRs are receipts, issued by foreign banks or trust companies,\nor foreign branches of U.S. banks, that represent an interest in shares of either a foreign or U.S. corporation. These instruments may\nnot necessarily be denominated in the same currency as the securities into which they may be converted. ADRs and GDRs generally involve\nthe same types of risks as foreign common stock held directly. Some ADRs and GDRs may experience less liquidity than the underlying common\nstocks traded in their home market. The Portfolios may invest in sponsored or unsponsored ADRs. Unlike a sponsored ADR where the depositary\nhas an exclusive relationship with the foreign issuer, an unsponsored ADR may be created by a depositary institution independently and\nwithout the cooperation of the foreign issuer. Consequently, information concerning the foreign issuer may be less current or reliable\nfor an unsponsored ADR and the price of an unsponsored ADR may be more volatile than if it was a sponsored ADR. Depositaries of unsponsored\nADRs are not required to distribute shareholder communications received from the foreign issuer or to pass through voting rights to its\nholders. The holders of unsponsored ADRs generally bear all the costs associated with establishing the unsponsored ADR, whereas the foreign\nissuers typically bear certain costs in a sponsored ADR.

Foreign companies may not be subject to the\nsame disclosure, accounting, auditing and financial reporting standards and practices as U.S. companies. Thus, there may be less information\npublicly available about foreign companies than about most U.S. companies.

Certain foreign securities may be less liquid\n(harder to sell) and more volatile than many U.S. securities. This means the Portfolios may at times be unable to sell foreign securities\nin a timely manner or at favorable prices.

European Issuers. The Global Dividend\nSustainability Portfolio and International Dividend Sustainability Portfolio are concentrated in securities issued by European companies.\nInvestments in a single region, even though representing a number of different countries within the region, may be affected by common\neconomic forces and other factors. A significant number of countries in Europe are member states in the EU, and those that have adopted\nthe euro generally share a common monetary policy determined by the European Central Bank. EU member states that have not adopted the\neuro retain their own monetary policies. Political or economic disruptions in European countries, even in countries in which your Portfolio\nis not invested, may adversely affect security values and thus the Portfolio’s holdings. The risks associated with investing in\nEuropean securities may be heightened because of risks due to the inexperience of financial intermediaries, the lack of modern technology,\nthe lack of a sufficient capital base to expand business operations and the possibility of permanent or temporary termination of trading\nand greater spreads between bid and asked prices for securities in those markets.

Switzerland. The International\nDividend Sustainability Portfolio invests significantly in stocks issued by

A-4

companies located in Switzerland. Although Switzerland is not\na member of the EU, the Swiss economy is dependent on the economies of other European nations as key trading partners. Any reduction\nin spending by other European countries could have a negative effect on the Swiss economy. Since Switzerland has few natural resources,\nany fluctuation or shortage in the commodity markets could have a negative impact on the nation’s economy.

Canada. The International Dividend\nSustainability Portfolio is concentrated in stocks issued by companies headquartered, or with a significant presence, in Canada. Canada\nis a major producer of commodities, including forest products, metals, agricultural products and energy related products, including oil,\ngas, and hydroelectricity. Accordingly, changes in the supply and demand of base commodity resources and industrial and precious metals\nand materials, both domestically and internationally, can have a significant effect on Canadian market performance.

Sector Risks. The Portfolios\ninvest significantly, or are concentrated, in certain sectors. Any negative impact on these sectors will have a greater impact on the\nvalue of Units than on a portfolio diversified over several sectors. You should understand the risks of these sectors before you invest.

The relative weighting or composition of your\nPortfolio may change during the life of your Portfolio. Following the Initial Date of Deposit, the Sponsor intends to issue additional\nUnits by depositing in your Portfolio additional securities in a manner consistent with the provisions described in the above section\nentitled “The Portfolios”. As described in that section, it may not be possible to retain or continue to purchase one or more\nSecurities in your Portfolio. In addition, due to certain limited circumstances described under “Portfolio Administration”,\nthe composition of the Securities in your Portfolio may change. Accordingly, the fluctuations in the relative weighting or composition\nof your Portfolio may result in concentrations (25% or more of a Portfolio’s assets) in securities of a particular type, sector\nand/or geographic region. As of the Initial Date of Deposit, each Portfolio was significantly invested in the following to the extent\ndescribed below.

Consumer Discretionary and Consumer Staples\nIssuers. The Dividend Sustainability Portfolio and the Global Dividend Sustainability Portfolio are concentrated, and the International\nDividend Sustainability Portfolio invests significantly, in companies that manufacture or sell various consumer products. General risks\nof these companies include the overall state of the economy, intense competition and consumer spending trends. A decline in the economy\nwhich results in a reduction of consumers’ disposable income can negatively impact spending habits. Global factors including political\ndevelopments, imposition of import controls, fluctuations in oil prices, and changes in exchange rates may adversely affect issuers of\nconsumer products and services.

Competitiveness in the retail industry may\nrequire large capital outlays for the installation of automated checkout equipment to control inventory, track the sale of items and gauge\nthe success of sales campaigns. Retailers who sell their products over the Internet have the potential to access more consumers, but may\nrequire sophisticated technology to remain competitive. Changes in demographics and consumer tastes can also affect the demand for, and\nthe success of, consumer products and services in the marketplace. Consumer products and services companies may be subject to government\nregulation affecting their products and operations which may negatively impact performance. Tobacco companies may be adversely affected\nby new laws, regulations and litigation.

Health Care Issuers. The Portfolios\neach invest significantly in health care companies. These issuers include companies involved in advanced medical devices and instruments,\ndrugs and biotechnology, managed care, hospital management/health services and medical supplies. These companies face substantial government\nregulation and approval procedures. General risks of health care companies include extensive competition, product liability litigation\nand evolving government regulation.

On March 30, 2010, the Health Care and Education\nReconciliation Act of 2010 (incorporating the Patient Protection and Affordable Care Act, collectively the “Act”) was enacted\ninto law in the United States. The Act continues to have a significant impact on the health care

A-5

sector through the implementation of a number of reforms in a complex\nand ongoing process, with varying effective dates.

Significant provisions of the Act include\nthe introduction of required health care coverage for most Americans, significant expansion in the number of Americans eligible for Medicaid,\nmodification of taxes and tax credits in the health care sector, and subsidized insurance for low to middle income families. The Act also\nprovides for more thorough regulation of private health insurance providers, including a prohibition on the denial of coverage due to\npre-existing conditions. Health care companies will face continuing and significant changes that may cause a decrease in profitability\ndue to increased costs and changes in the health care market. In late 2017, along with the passage of sweeping tax reform, legislation\nwas passed which eliminated the individual mandate (a penalty for failure to obtain a minimum level of health insurance coverage) beginning\nin 2019. It is estimated that the repeal of the individual mandate will cause a significant amount of people to be uninsured which may\nhave an adverse effect on insurance premiums and federal subsidies. The Sponsor is unable to predict the full impact of the Act, or of\nits potential repeal or modification, on the Securities in your Portfolio.

As illustrated by the Act, Congress may from\ntime to time propose legislative action that will impact the health care sector. The proposals may span a wide range of topics, including\ncost and price controls (which may include a freeze on the prices of prescription drugs), incentives for competition in the provision\nof health care services, promotion of pre-paid health care plans and additional tax incentives and penalties aimed at the health care\nsector. The government could also reduce funding for health care related research.

Drug and medical products companies face the\nrisk of increasing competition from new products or services, generic drug sales, product obsolescence, increased government regulation,\ntermination of patent protection for drug or medical supply products and the risk that a product will never come to market. The research\nand development costs of bringing a new drug or medical product to market are substantial. This process involves lengthy government review\nwith no guarantee of approval. These companies may have losses and may not offer proposed products for several years, if at all. The failure\nto gain approval for a new drug or product can have a substantial negative effect on a company and its stock. The goods and services of\nhealth care issuers are also subject to risks of malpractice claims, product liability claims or other litigation, which may be especially\ncostly and slow with foreign health care issuers. Special problems may arise in attempting to enforce claims against foreign governments.

Health care facility operators face risks\nrelated to demand for services, the ability of the facility to provide required services, an increased emphasis on outpatient services,\nconfidence in the facility, management capabilities, competitive forces that may result in price discounting, efforts by insurers and\ngovernment agencies to limit rates, expenses, the cost and possible unavailability of malpractice insurance, and termination or restriction\nof government financial assistance (such as Medicare, Medicaid or similar programs).

Foreign health care companies pose additional\nrisks due to political, social and economic developments or instability abroad; global health pandemics; the threat of terrorist attacks;\nthe differences between regulations in the U.S. and regulations abroad; the seizure by the government of company assets; excessive taxation;\nwithholding taxes on dividends and interest; different accounting standards; and limitations on the use or transfer of portfolio assets.\nCompliance with the Foreign Corrupt Practices Act is also of concern, particularly in developing countries where there tends to be a higher\nrisk of corruption in the life sciences industry.

In the United Kingdom, Parliament in 2012\nenacted the Health and Social Care Act (“Act”), which reorganized the health care system. Significant provisions of the Act\ninclude the creation of new health boards to oversee services and allocate resources, among other things. The Act continues to have an\nimpact as it effectuates further reform within the United Kingdom.

Elsewhere in Europe, country-specific regulations\nand reforms also continue to have a significant impact on the health care sector. In France, a regulation that introduced

A-6

formal medioeconomic assessments into the approval and pricing\ndecisions of drugs impacted biopharma companies. In Germany, a new “treatment contract” was instituted to govern patient-provider\nrelationships. The Sponsor is unable to predict the full impact of these reforms on the Securities in your Portfolio.

Industrials Issuers. The Portfolios\neach invest significantly in industrials companies. General risks of industrials companies include the general state of the economy, intense\ncompetition, imposition of import controls, volatility in commodity prices, currency exchange rate fluctuation, consolidation, labor relations,\ndomestic and international politics, excess capacity and consumer spending trends. Companies in the industrials sector may be adversely\naffected by liability for environmental damage and product liability claims. Capital goods companies may also be significantly affected\nby overall capital spending and leverage levels, economic cycles, technical obsolescence, delays in modernization, limitations on supply\nof key materials, depletion of resources, government regulations, government contracts and e-commerce initiatives.

Industrials companies may also be affected\nby factors more specific to their individual industries. Industrial machinery manufacturers may be subject to declines in commercial and\nconsumer demand and the need for modernization. Aerospace and defense companies may be influenced by decreased demand for new equipment,\naircraft order cancellations, disputes over or ability to obtain or retain government contracts, changes in government budget priorities,\nchanges in aircraft-leasing contracts and cutbacks in profitable business travel. The number of housing starts, levels of public and nonresidential\nconstruction including weakening demand for new office and retail space, and overall construction spending may adversely affect construction\nmaterials and equipment manufacturers. Stocks of transportation companies are cyclical and can be significantly affected by economic changes,\nfuel prices and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation\nand oversight, which may negatively impact their businesses.

Information Technology Issuers. The\nInternational Dividend Sustainability Portfolio invests significantly in companies in the information technology sector. These companies\ninclude companies that are involved in computer and business services, enterprise software/technical software, Internet and computer software,\nInternet-related services, networking and telecommunications equipment, telecommunications services, electronics products, server hardware,\ncomputer hardware and peripherals, semiconductor capital equipment and semiconductors.

These companies face risks related to rapidly\nchanging technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions.\nCompanies in this sector face risks from rapid changes in technology, competition, dependence on certain suppliers and supplies, rapid\nobsolescence of products or services, patent termination, frequent new products and government regulation. These companies can also be\nadversely affected by interruption or reduction in supply of components or loss of key customers and failure to comply with certain industry\nstandards. To the extent the information technology companies in your Portfolio are exposed to the artificial intelligence (“AI”)\nindustry, investors should be aware that rapid advancements and regulatory changes in AI technology may significantly impact the operational\nand financial performance of these companies. Additionally, increased competition and potential ethical concerns related to AI deployment\ncould pose substantial risks to their market position and reputation.

An unexpected change in technology can have\na significant negative impact on a company. The failure of a company to introduce new products or technologies or keep pace with rapidly\nchanging technology can have a negative impact on the company’s results. Information technology companies may also be smaller and/or\nless experienced companies with limited product lines, markets or resources. Stocks of some Internet companies have high price-to-earnings\nratios with little or no earnings histories. Information technology stocks tend to experience substantial price volatility and speculative\ntrading. Announcements about new products, technologies, operating results or marketing alliances can cause stock prices to fluctuate\ndramatically. At times, however, extreme price and volume fluctuations are unrelated to the operating performance of a company.

A-7

This can impact your ability to redeem your Units at a price equal\nto or greater than what you paid.

Cybersecurity Risk. With the\nincreased use of technologies such as the Internet to conduct business, your Portfolio may be susceptible to operational, information\nsecurity and related risks. Cybersecurity incidents involving your Portfolio and its service providers (including, without limitation,\nthe Sponsor and the Trustee) have the ability to cause disruptions and impact business operations, potentially resulting in financial\nlosses, impediments to trading, the inability of Unitholders to transact business, violations of applicable privacy and other laws, regulatory\nfines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. Similar adverse\nconsequences could result from cybersecurity incidents affecting issuers of securities in which your Portfolio invests, counterparties\nwith which your Portfolio engages, governmental and other regulatory authorities, exchanges and other financial market operators, banks,\nbrokers, dealers, insurance companies, other financial institutions and other parties. Your Portfolio and its Unitholders could be negatively\nimpacted as a result.

Legislation/Litigation. From\ntime to time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain\nof the companies represented in your Portfolio, or on the tax treatment of your Portfolio or of your investment in a Portfolio. In addition,\nlitigation regarding any of the issuers of the Securities or of the sectors represented by these issuers may negatively impact the share\nprices 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. Liquidity risk\nis the risk that the value of a security will fall if trading in the security is limited or absent. The market for certain investments\nmay become less liquid or illiquid due to adverse changes in the conditions of a particular issuer or due to adverse market or economic\nconditions. In the absence of a liquid trading market for a particular security, the price at which such security may be sold to meet\nredemptions, as well as the value of the Units of your Portfolio, may be adversely affected. No one can guarantee that a liquid trading\nmarket will exist for any security.

No FDIC Guarantee. An investment\nin your Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other\ngovernment agency.

PUBLIC OFFERING

General. Units are offered at\nthe Public Offering Price which consists of the net asset value per Unit plus organization costs plus the sales charge. The net asset\nvalue per Unit is the value of the securities, cash and other assets in your Portfolio reduced by the liabilities of the Portfolio divided\nby the total Units outstanding. The maximum sales charge equals 2.75% of the Public Offering Price per Unit (2.828% of the aggregate offering\nprice of the Securities) at the time of purchase.

The initial sales charge is the difference\nbetween the total sales charge amount (maximum of 2.75% of the Public Offering Price per Unit) and the sum of the remaining fixed dollar\ndeferred sales charge and the fixed dollar creation and development fee (initially $0.275 per Unit). Depending on the Public Offering\nPrice per Unit, you pay the initial sales charge at the time you buy Units. The deferred sales charge is fixed at $0.225 per Unit. Your\nPortfolio pays the deferred sales charge in installments as described in the “Fee Table.” If any deferred sales charge payment\ndate is not a business day, we will charge the payment on the next business day. If you purchase Units after the initial deferred sales\ncharge payment, you will only pay that portion of the payments not yet collected. If you redeem or sell your Units prior to collection\nof the total deferred sales charge, you will pay any remaining deferred sales charge upon redemption or sale of your Units. The initial\nand deferred sales charges are referred to as the “transactional sales charge.” The transactional sales charge does not include\nthe creation and development fee which compensates the Sponsor for creating and developing your Portfolio and is described under “Expenses.”\nThe creation and development fee is fixed at $0.05 per Unit. Your Portfolio pays the creation and development fee as of the close of the\ninitial offering period as described in the “Fee

A-8

Table.” If you redeem or sell your Units prior to collection\nof the creation and development fee, you will not pay the creation and development fee upon redemption or sale of your Units. After the\ninitial offering period the maximum sales charge will be reduced by 0.50%, reflecting the previous collection of the creation and development\nfee. Because the deferred sales charge and creation and development fee are fixed dollar amounts per Unit, the actual charges will exceed\nthe percentages shown in the “Fee Table” if the Public Offering Price per Unit falls below $10 and will be less than the percentages\nshown in the “Fee Table” if the Public Offering Price per Unit exceeds $10. In no event will the maximum total sales charge\nexceed 2.75% of the Public Offering Price per Unit.

The “Fee Table” shows the sales\ncharge calculation at a $10 Public Offering Price per Unit. At a $10 Public Offering Price, there is no initial sales charge during the\ninitial offering period. If the Public Offering Price exceeds $10 per Unit, you will pay an initial sales charge equal to the difference\nbetween the total sales charge and the sum of the remaining deferred sales charge and the creation and development fee. For example, if\nthe Public Offering Price per Unit rose to $14, the maximum sales charge would be $0.385 (2.75% of the Public Offering Price per Unit),\nconsisting of an initial sales charge of $0.110, a deferred sales charge of $0.225 and the creation and development fee of $0.050. Since\nthe deferred sales charge and creation and development fee are fixed dollar amounts per Unit, your Portfolio must charge these amounts\nper Unit regardless of any decrease in net asset value. However, if the Public Offering Price per Unit falls to the extent that the maximum\nsales charge percentage results in a dollar amount that is less than the combined fixed dollar amounts of the deferred sales charge and\ncreation and development fee, your initial sales charge will be a credit equal to the amount by which these fixed dollar charges exceed\nyour sales charge at the time you buy Units. In such a situation, the value of securities per Unit would exceed the Public Offering Price\nper Unit by the amount of the initial sales charge credit and the value of those securities will fluctuate, which could result in a benefit\nor detriment to Unitholders that purchase Units at that price. The initial sales charge credit is paid by the Sponsor and is not paid\nby your Portfolio. If the Public Offering Price per Unit fell to $6, the maximum sales charge would be $0.165 (2.75% of the Public Offering\nPrice per Unit), which consists of an initial sales charge (credit) of -$0.110, a deferred sales charge of $0.225 and a creation and development\nfee of $0.050.

The actual sales charge that may be paid by\nan investor may differ slightly from the sales charges shown herein due to rounding that occurs in the calculation of the Public Offering\nPrice and in the number of Units purchased.

The minimum purchase is 100 Units (25 Units\nfor retirement accounts) but may vary by selling firm. Certain broker-dealers or selling firms may charge an order handling fee for processing\nUnit purchases.

Reducing Your Sales Charge. The\nSponsor offers ways for you to reduce the sales charge that you pay. It is your financial professional’s responsibility to alert\nthe Sponsor of any discount when you purchase Units. Before you purchase Units you must also inform your financial professional of your\nqualification for any discount to be eligible for a reduced sales charge. Since the deferred sales charges and creation and development\nfee are fixed dollar amounts per Unit, your Portfolio must charge these amounts per Unit regardless of any discounts. However, if you\nare eligible to receive a discount such that your total sales charge is less than the fixed dollar amounts of the deferred sales charges\nand creation and development fee, you will receive a credit equal to the difference between your total sales charge and these fixed dollar\ncharges at the time you buy Units.

Fee Accounts. Investors may purchase\nUnits through registered investment advisers, certified financial planners and registered broker-dealers who in each case either charge\nperiodic fees for brokerage services, financial planning, investment advisory or asset management services, or provide such services in\nconnection with the establishment of an investment account for which a comprehensive “fee based” charge (“Fee Based”)\nis imposed (“Fee Accounts”). If Units of a Portfolio are purchased for a Fee Account and the Portfolio is subject to a Fee\nBased charge (i.e., the Portfolio is “Fee Based Eligible”), then the purchase will not be subject to the transactional sales\ncharge but will be subject to the

A-9

creation and development fee of $0.05 per Unit that is retained\nby the Sponsor. Please refer to the section called “Fee Accounts” for additional information on these purchases. The Sponsor\nreserves the right to limit or deny purchases of Units described in this paragraph by investors or selling firms whose frequent trading\nactivity is determined to be detrimental to a Portfolio. Fee Based Eligible Units are not eligible for any sales charge discounts in addition\nto that which is described in this paragraph and under the “Fee Accounts” section found below.

Certain Self-Directed Brokerage Platforms.\nPurchases of Units through E*TRADE and/or any other Morgan Stanley self-directed brokerage platform will be executed at the Public\nOffering Price less the applicable dealer concession.

Employees. Employees, officers and\ndirectors (including their spouses (or the equivalent if recognized under local law) and children or step-children under 21 living in\nthe same household, parents or step-parents and trustees, custodians or fiduciaries for the benefit of such persons) of Invesco Capital\nMarkets, Inc. and its affiliates, and dealers and their affiliates may purchase Units at the Public Offering Price less the applicable\ndealer concession. All employee discounts are subject to the policies of the related selling firm, including any eligibility limitations\nenforced by the selling firm. Only employees, officers and directors of companies that allow their employees to participate in this employee\ndiscount program are eligible for the discounts.

Distribution Reinvestments. We do not\ncharge any sales charge when you reinvest distributions from your Portfolio into additional Units of your Portfolio. Since the deferred\nsales charge and creation and development fee are fixed dollar amounts per unit, your Portfolio must charge these amounts per unit regardless\nof this discount. If you elect to reinvest distributions, the Sponsor will credit you with additional Units with a dollar value sufficient\nto cover the amount of any remaining deferred sales charge and creation and development fee that will be collected on such Units at the\ntime of reinvestment. The dollar value of these Units will fluctuate over time.

Unit Price. The Public Offering\nPrice of Units will vary from the amounts stated under “Essential Information” in accordance with fluctuations in the prices\nof the underlying Securities in the Portfolios. The initial price of the Securities upon deposit by the Sponsor was determined by the\nEvaluator. The Evaluator will generally determine the value of the Securities as of the Evaluation Time on each business day and will\nadjust the Public Offering Price of Units accordingly. The Evaluation Time is the close of the New York Stock Exchange on each business\nday. The term “business day”, as used herein and under “Rights of Unitholders--Redemption of Units”, means any\nday on which the New York Stock Exchange is open for regular trading. The Public Offering Price per Unit will be effective for all orders\nreceived prior to the Evaluation Time on each business day. Orders received by the Sponsor prior to the Evaluation Time and orders received\nby authorized financial professionals prior to the Evaluation Time that are properly transmitted to the Sponsor by the time designated\nby the Sponsor, are priced based on the date of receipt. Orders received by the Sponsor after the Evaluation Time, and orders received\nby authorized financial professionals after the Evaluation Time or orders received by such persons that are not transmitted to the Sponsor\nuntil after the time designated by the Sponsor, are priced based on the date of the next determined Public Offering Price per Unit provided\nthey are received timely by the Sponsor on such date. It is the responsibility of authorized financial professionals to transmit orders\nreceived by them to the Sponsor so they will be received in a timely manner.

The value of portfolio securities is based\non the securities’ market price when available. When a market price is not readily available, including circumstances under which\nthe Evaluator determines that a security’s market price is not accurate, a portfolio security is valued at its fair value, as determined\nunder procedures established by the Evaluator or an independent pricing service used by the Evaluator. In these cases, a Portfolio’s\nnet asset value will reflect certain portfolio securities’ fair value rather than their market price. With respect to securities\nthat are primarily listed on foreign exchanges, the value of the portfolio securities may change on days when you will not be able to\npurchase or sell Units. The value of any foreign securities listed on foreign exchanges is based on the applicable currency exchange rate\nas of

A-10

the Evaluation Time. The Sponsor will provide price dissemination\nand oversight services to the Portfolios.

During the initial offering period, part of\nthe Public Offering Price represents an amount that will pay the costs incurred in establishing your Portfolio. These costs include the\ncosts of preparing documents relating to your Portfolio (such as the registration statement, prospectus, trust agreement and legal documents),\nfederal and state registration fees, the initial fees and expenses of the Trustee and the initial audit. Your Portfolio will sell securities\nto 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\ndecline when your Portfolio pays these costs.

Unit Distribution. Units will\nbe distributed to the public by the Sponsor, broker-dealers and others at the Public Offering Price. Units repurchased in the secondary\nmarket, if any, may be offered by this prospectus at the secondary market Public Offering Price in the manner described above.

Unit Sales Concessions. Brokers, dealers\nand others will be allowed a regular concession or agency commission in connection with the distribution of Units during the initial offering\nperiod of 2.00% of the Public Offering Price per Unit.

Volume Concession Based Upon Annual Sales.\nAs described below, broker-dealers and other selling agents may in certain cases be eligible for an additional concession based upon their\nannual eligible sales of all Invesco fixed income and equity unit investment trusts. Eligible sales include all units of any Invesco unit\ninvestment trust underwritten or purchased directly from Invesco during a trust’s initial offering period. For purposes of this\nconcession, trusts designated as either “Invesco Unit Trusts, Taxable Income Series” or “Invesco Unit Trusts, Municipal\nSeries” are fixed income trusts, and trusts designated as “Invesco Unit Trusts Series” are equity trusts. In addition\nto the regular concessions or agency commissions described above in “Unit Sales Concessions” all broker-dealers and other\nselling firms will be eligible to receive additional compensation based on total initial offering period sales of all eligible Invesco\nunit investment trusts during the previous consecutive 12-month period through the end of the most recent month. The Volume Concession,\nas applicable to equity and fixed income trust units, is set forth in the following table:

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n


	Volume Concession
Total Sales	Equity Trust	Fixed Income
(in millions)	Units	Trust Units
$25 but less than $100	0.035%	0.100%
$100 but less than $150	0.050	0.100
$150 but less than $250	0.075	0.100
$250 but less than $1,000	0.100	0.100

$5,000 but less than $7,500	0.150	0.100
$7,500 or more	0.175	0.100

Broker-dealers and other selling firms will\nnot receive the Volume Concession on the sale of units purchased in Fee Accounts, however, such sales will be included in determining\nwhether a firm has met the sales level breakpoints set forth in the Volume Concession table above. Secondary market sales of all unit\ninvestment trusts are excluded for purposes of the Volume Concession. Eligible dealer firms and other selling agents include clearing\nfirms that place orders with Invesco and provide Invesco with information with respect to the representatives who initiated such transactions.\nEligible dealer firms and other selling agents will not include firms that solely provide clearing services to other broker-dealer firms\nor firms who place orders through clearing firms that are eligible dealers. We reserve the right to change the amount of the concessions\nor agency commissions from time to time. For a trust to be eligible for this additional compensation, the trust’s prospectus must\ninclude disclosure related to this additional compensation.

Additional Information. Except as provided\nin this section, any sales charge discount provided to investors will be borne by the selling broker-dealer or agent. For all secondary\nmarket transactions the total concession or agency commission will amount to 80% of the applicable sales charge. Notwithstanding anything\nto the contrary herein, in no case shall the total of any concessions, agency commissions and any additional compensation allowed or paid\nto any broker, dealer or other distributor of Units with respect to any individual transaction exceed the total sales charge applicable\nto such transaction. The

A-11

Sponsor reserves the right to reject, in whole or in part, any\norder for the purchase of Units and to change the amount of the concession or agency commission to dealers and others from time to time.

We may provide, at our own expense and out\nof our own profits, additional compensation and benefits to broker-dealers who sell Units of the Portfolios and our other products. This\ncompensation is intended to result in additional sales of our products and/or compensate broker-dealers and financial advisors for past\nsales. We may make these payments for marketing, promotional or related expenses, including, but not limited to, expenses of entertaining\nretail customers and financial advisors, advertising, sponsorship of events or seminars, obtaining shelf space in broker-dealer firms\nand similar activities designed to promote the sale of the Portfolios and our other products. Fees may include payment for travel expenses,\nincluding lodging, incurred in connection with trips taken by invited registered representatives for meetings or seminars of a business\nnature. These arrangements will not change the price you pay for your Units.

Sponsor Compensation. The Sponsor\nwill receive the total sales charge applicable to each transaction. Except as provided under “Unit Distribution,” any sales\ncharge discount provided to investors will be borne by the selling dealer or agent. In addition, the Sponsor will realize a profit or\nloss as a result of the difference between the price paid for the Securities by the Sponsor and the cost of the Securities to your Portfolio\non the Initial Date of Deposit as well as on subsequent deposits. The Sponsor has not participated as sole underwriter or as manager or\nas a member of the underwriting syndicates or as an agent in a private placement for any of the Securities. The Sponsor may realize profit\nor loss as a result of the possible fluctuations in the market value of Units held by the Sponsor for sale to the public. In maintaining\na secondary market, the Sponsor will realize profits or losses in the amount of any difference between the price at which Units are purchased\nand the price at which Units are resold (which price includes the applicable sales charge) or from a redemption of repurchased Units at\na price above or below the purchase price. Cash, if any, made available to the Sponsor prior to the date of settlement for the purchase\nof 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\nSecurities Exchange Act of 1934, as amended (“1934 Act”).

The Sponsor or an affiliate may have participated\nin a public offering of one or more of the Securities. The Sponsor, an affiliate or their employees may have a long or short position\nin these Securities or related securities. An affiliate may act as a specialist or market maker for these Securities. An officer, director\nor employee of the Sponsor or an affiliate may be an officer or director for issuers of the Securities.

Market for Units. Although it\nis not obligated to do so, the Sponsor may maintain a market for Units and to purchase Units at the secondary market repurchase price\n(which is described under “Right of Unitholders--Redemption of Units”). The Sponsor may discontinue purchases of Units or\ndiscontinue purchases at this price at any time. In the event that a secondary market is not maintained, a Unitholder will be able to\ndispose of Units by tendering them to the Trustee for redemption at the Redemption Price. See “Rights of Unitholders--Redemption\nof Units”. Unitholders should contact their broker to determine the best price for Units in the secondary market. Units sold prior\nto the time the entire deferred sales charge has been collected will be assessed the amount of any remaining deferred sales charge at\nthe time of sale. The Trustee will notify the Sponsor of any Units tendered for redemption. If the Sponsor’s bid in the secondary\nmarket equals or exceeds the Redemption Price per Unit, it may purchase the Units not later than the day on which Units would have been\nredeemed by the Trustee. The Sponsor may sell repurchased Units at the secondary market Public Offering Price per Unit.

RETIREMENT ACCOUNTS

Units are available for purchase in connection\nwith certain types of tax-sheltered retirement plans, including Individual Retirement Accounts for individuals, Simplified Employee Pension\nPlans for employees, qualified plans for self-employed individuals, and qualified corporate pension and profit sharing plans for employees.\nThe minimum purchase for these accounts is reduced to 25

A-12

Units but may vary by selling firm. The purchase of Units may be\nlimited by the plans’ provisions and does not itself establish such plans.

FEE ACCOUNTS

As described above, Units may be available\nfor purchase by investors in Fee Accounts where a Portfolio is Fee Based Eligible. You should consult your financial professional to determine\nwhether you can benefit from these accounts. This table illustrates the sales charge you will pay if a Portfolio is Fee Based Eligible\nas a percentage of the initial Public Offering Price per Unit on the Initial Date of Deposit (the percentage will vary thereafter).

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n


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

You should consult the “Public Offering--Reducing\nYour Sales Charge” section for specific information on this and other sales charge discounts. That section governs the calculation\nof all sales charge discounts. The Sponsor reserves the right to limit or deny purchases of Units in Fee Accounts by investors or selling\nfirms whose frequent trading activity is determined to be detrimental to a Portfolio. To purchase Units in these Fee Accounts, your financial\nprofessional must purchase Units designated with one of the Fee Based CUSIP numbers set forth under “Essential Information,”\neither Fee Based Cash for cash distributions or Fee Based Reinvest for the reinvestment of distributions in additional Units, if available.\nSee “Rights of Unitholders--Reinvestment Option.”

RIGHTS OF UNITHOLDERS

Distributions. Dividends and\ninterest, net of expenses, and any net proceeds from the sale of Securities received by a Portfolio will generally be distributed to Unitholders\non each Distribution Date to Unitholders of record on the preceding Record Date. These dates appear under “Essential Information”.\nDistributions made by the securities in your Portfolio include ordinary income, but may also include sources other than ordinary income\nsuch as returns of capital, loan proceeds, short-term capital gains and long-term capital gains (see “Taxation--Distributions”).\nIn addition, the Portfolios will generally make required distributions at the end of each year because each is structured as a “regulated\ninvestment company” for federal tax purposes. Unitholders will also receive a final distribution of income when their Portfolio\nterminates. A person becomes a Unitholder of record on the date of settlement (generally one business day, or as otherwise may be required\nby the applicable rules under the 1934 Act). Unitholders may elect to receive distributions in cash or to have distributions reinvested\ninto additional Units. See “Rights of Unitholders--Reinvestment Option”.

Dividends and interest received by a Portfolio\nare credited to the Income Account of the Portfolio. Other receipts (e.g., capital gains, proceeds from the sale of Securities,\netc.) are credited to the Capital Account. Proceeds received on the sale of any Securities, to the extent not used to meet redemptions\nof Units or pay deferred sales charges, fees or expenses, will be distributed to Unitholders. Proceeds received from the disposition of\nany Securities after a Record Date and prior to the following Distribution Date will be held in the Capital Account and not distributed\nuntil the next Distribution Date. Any distribution to Unitholders consists of each Unitholder’s pro rata share of the available\ncash in the Income and Capital Accounts as of the related Record Date.

Historical 12 Month Distributions. The\nHistorical 12 Month Distributions per Unit amount shown under “Essential Information” is based upon the weighted average of\nthe actual distributions paid by the securities included in your Portfolio over the 12 months preceding the Initial Date of Deposit, divided\nby the Portfolio’s initial public offering price of $10 per Unit. This amount is reduced by the anticipated per Unit fees and expenses\nwhich will be incurred when investing in your Portfolio. Dividend payments are not assured and therefore the amount of future dividend\nincome to your Portfolio is uncertain. Accordingly, the actual net annual income distributions you receive per Unit will vary from the\nHistorical 12 Month Distributions amount per Unit due to

A-13

changes in dividends and distribution amounts paid by issuers,\ncurrency fluctuations, the sale of securities to pay any deferred sales charge, Portfolio fees and expenses, and with changes in your\nPortfolio such as the acquisition, call, maturity or sale of securities. The sale of securities to pay such fees and expenses may cause\nthe amount of your distributions decrease over your Portfolio’s life. Due to these and various other factors, actual income received\nby your Portfolio will most likely differ from the most recent dividends or scheduled income payments of the underlying Portfolio securities.

Reinvestment Option. Unitholders\nmay have distributions automatically reinvested in additional Units without a sales charge (to the extent Units may be lawfully offered\nfor sale in the state in which the Unitholder resides). The CUSIP numbers for either “Cash” distributions or “Reinvest”\nfor the reinvestment of distributions are set forth under “Essential Information”. Brokers and dealers can use the Dividend\nReinvestment Service through Depository Trust Company (“DTC”) or purchase a Reinvest (or Fee Based Reinvest in the case of\nFee Based Eligible Units held in Fee Accounts) CUSIP, if available. To participate in this reinvestment option, a Unitholder must file\nwith the Trustee a written notice of election, together with any other documentation that the Trustee may then require, at least five\ndays prior to the related Record Date. A Unitholder’s election will apply to all Units owned by the Unitholder and will remain in\neffect until changed by the Unitholder. The reinvestment option is not offered during the 30 calendar days prior to termination. If Units\nare unavailable for reinvestment or this reinvestment option is no longer available, distributions will be paid in cash. Distributions\nwill be taxable to Unitholders if paid in cash or automatically reinvested in additional Units. See “Taxation”.

A participant may elect to terminate his or\nher reinvestment plan and receive future distributions in cash by notifying the Trustee in writing no later than five days before a Distribution\nDate. The Sponsor shall have the right to suspend or terminate the reinvestment plan at any time. The reinvestment plan is subject to\navailability or limitation by each broker-dealer or selling firm. Broker-dealers may suspend or terminate the offering of a reinvestment\nplan at any time. Please contact your financial professional for additional information.

Redemption of Units. All or\na portion of your Units may be tendered to The Bank of New York Mellon, the Trustee, for redemption at Unit Investment Trust Division,\n111 Sanders Creek Parkway, East Syracuse, New York 13057, on any day the New York Stock Exchange is open. No redemption fee will be charged\nby the Sponsor or the Trustee, but you are responsible for applicable governmental charges, if any. Units redeemed by the Trustee will\nbe canceled. You may redeem all or a portion of your Units by sending a request for redemption to your bank or broker-dealer through which\nyou hold your Units. No later than one business day (or as otherwise may be required by the applicable rules under the 1934 Act) following\nsatisfactory tender, the Unitholder will be entitled to receive in cash an amount for each Unit equal to the Redemption Price per Unit\nnext computed on the date of tender. The “date of tender” is deemed to be the date on which Units are received by the Trustee,\nexcept that with respect to Units received by the Trustee after the Evaluation Time or on a day which is not a business day, the date\nof tender is deemed to be the next business day. Redemption requests received by the Trustee after the Evaluation Time, and redemption\nrequests received by authorized financial professionals after the Evaluation Time or redemption requests received by such persons that\nare not transmitted to the Trustee until after the time designated by the Trustee, are priced based on the date of the next determined\nredemption price provided they are received timely by the Trustee on such date. It is the responsibility of authorized financial professionals\nto transmit redemption requests received by them to the Trustee so they will be received in a timely manner. Certain broker-dealers or\nselling firms may charge an order handling fee for processing redemption requests. Units redeemed directly through the Trustee are not\nsubject to such fees.

Unitholders tendering 1,000 or more Units\nof a Portfolio (or such higher amount as may be required by your broker-dealer or selling agent) for redemption may request an in kind\ndistribution of Securities equal to the Redemption Price per Unit on the date of tender. Unitholders may not request an in kind distribution\nduring

A-14

the initial offering period or within 30 calendar days of a Portfolio’s\ntermination. Your Portfolio generally will not offer in kind distributions of portfolio securities that are held in foreign markets. An\nin kind distribution will be made by the Trustee through the distribution of each of the Securities in book-entry form to the account\nof the Unitholder’s broker-dealer at DTC. Amounts representing fractional shares will be distributed in cash. The Trustee may adjust\nthe number of shares of any Security included in a Unitholder’s in kind distribution to facilitate the distribution of whole shares.\nThe in kind distribution option may be modified or discontinued at any time without notice. Notwithstanding the foregoing, if the Unitholder\nrequesting an in kind distribution is the Sponsor or an affiliated person of a Portfolio, the Trustee may make an in kind distribution\nto such Unitholder provided that no one with a pecuniary incentive to influence the in kind distribution may influence selection of the\ndistributed securities, the distribution must consist of a pro rata distribution of all portfolio securities (with limited exceptions)\nand the in kind distribution may not favor such affiliated person to the detriment of any other Unitholder. Unitholders will incur transaction\ncosts in liquidating securities received in an in-kind distribution, and any such securities received will be subject to market risk until\nsold. In the event that any securities received in-kind are illiquid, Unitholders will bear the risk of not being able to sell such securities\nin the near term, or at all.

The Trustee may sell Securities to satisfy\nUnit redemptions. To the extent that Securities are redeemed in kind or sold, the size of a Portfolio will be, and the diversity of a\nPortfolio may be, reduced. Sales may be required at a time when Securities would not otherwise be sold and may result in lower prices\nthan might otherwise be realized. The price received upon redemption may be more or less than the amount paid by the Unitholder depending\non the value of the Securities at the time of redemption. Special federal income tax consequences will result if a Unitholder requests\nan in kind distribution. See “Taxation”.

The Redemption Price per Unit and the secondary\nmarket repurchase price per Unit are equal to the pro rata share of each Unit in your Portfolio determined on the basis of (i) the cash\non hand in the Portfolio, (ii) the value of the Securities in the Portfolio and (iii) dividends or other income distributions receivable\non the Securities in the Portfolio trading ex-dividend as of the date of computation, less (a) amounts representing taxes or other governmental\ncharges payable out of the Portfolio, (b) the accrued expenses of the Portfolio (including costs associated with liquidating securities\nafter the end of the initial offering period) and (c) any unpaid deferred sales charge payments. During the initial offering period, the\nredemption price and the secondary market repurchase price are not reduced by the estimated organization costs or the creation and development\nfee. For these purposes, the Evaluator will determine the value of the Securities as described under “Public Offering--Unit Price”.

The right of redemption may be suspended and\npayment postponed for any period during which the New York Stock Exchange is closed, other than for customary weekend and holiday closings,\nor any period during which the SEC determines that trading on that Exchange is restricted or an emergency exists, as a result of which\ndisposal or evaluation of the Securities is not reasonably practicable, or for other periods as the SEC may permit.

Exchange Option. When you redeem\nUnits of your Portfolio or when your Portfolio terminates (see “Rollover” below), you may be able to exchange your Units for\nunits of other Invesco unit trusts. You should contact your financial professional for more information about trusts currently available\nfor exchanges. Before you exchange Units, you should read the prospectus of the new trust carefully and understand the risks and fees.\nYou should then discuss this option with your financial professional to determine whether your investment goals have changed, whether\ncurrent trusts suit you and to discuss tax consequences. A rollover or exchange is a taxable event to you. We may discontinue this option\nat any time.

Rollover. We may offer a subsequent\nseries of each Portfolio for a Rollover when the Portfolios terminate.

On the Mandatory Termination Date you will\nhave the option to (1) participate in a Rollover and have your Units reinvested into a subsequent trust series or (2) receive a cash distribution.

If you elect to participate in a cash Rollover,\nyour Units will be redeemed on the Mandatory Termination Date. As

A-15

the redemption proceeds become available, the proceeds (including\ndividends) will be invested in a new trust series at the public offering price for the new trust. The Trustee will attempt to sell Securities\nto satisfy the redemption as quickly as practicable on the Mandatory Termination Date. We do not anticipate that the sale period will\nbe longer than one day, however, certain factors could affect the ability to sell the Securities and could impact the length of the sale\nperiod. The liquidity of any Security depends on the daily trading volume of the Security and the amount available for redemption and\nreinvestment on any day.

We may make subsequent trust series available\nfor sale at various times during the year. Of course, we cannot guarantee that a subsequent trust or sufficient units will be available\nor that any subsequent trusts will offer the same investment strategies or objectives as the current Portfolios. We cannot guarantee that\na Rollover will avoid any negative market price consequences resulting from trading large volumes of securities. Market price trends may\nmake it advantageous to sell or buy securities more quickly or more slowly than permitted by the Portfolio procedures. We may, in our\nsole discretion, modify a Rollover or stop creating units of a trust at any time regardless of whether all proceeds of Unitholders have\nbeen reinvested in a Rollover. If we decide not to offer a subsequent series, Unitholders will be notified prior to the Mandatory Termination\nDate. Cash which has not been reinvested in a Rollover will be distributed to Unitholders shortly after the Mandatory Termination Date.\nRollover participants may receive taxable dividends or realize taxable capital gains which are reinvested in connection with a Rollover\nbut may not be entitled to a deduction for capital losses due to the “wash sale” tax rules. Due to the reinvestment in a subsequent\ntrust, no cash will be distributed to pay any taxes. See “Taxation”.

Units. Ownership of Units is\nevidenced in book-entry form only and will not be evidenced by certificates. Units purchased or held through your bank or broker-dealer\nwill be recorded in book-entry form and credited to the account of your bank or broker-dealer at DTC. Units are transferable by contacting\nyour bank or broker-dealer through which you hold your Units. Transfer, and the requirements therefore, will be governed by the applicable\nprocedures of DTC and your agreement with the DTC participant in whose name your Units are registered on the transfer records of DTC.

Reports Provided. Unitholders\nwill receive a statement of dividends and other amounts received by a Portfolio for each distribution.

In addition, at the end of each calendar year,\nthe Trustee will prepare a statement which contains the following information:

•

A summary of transactions in your Portfolio for the year;

•

A list of any Securities sold during the year and the Securities held at the end of that year by your Portfolio;

•

The Redemption Price per Unit and the number of Units outstanding, computed on the 31st day of December of such year (or the last\nbusiness day before); and

•

Amounts of income and capital distributed during the year.

Annual statements are made available at www.invesco.com/us/en/accounts/tax-center\nwithin a reasonable period of time after the end of each calendar year. You may also request an annual statement be sent to you by\ncalling the Trustee at 800-856-8487. Unitholders may obtain evaluations of the Securities upon request to the Trustee.

If you have questions regarding your account\nor your Portfolio, please contact your financial advisor or the Trustee. The Sponsor does not have access to individual account information.

PORTFOLIO ADMINISTRATION

Portfolio Administration. Your\nPortfolio is not a managed fund and, except as provided in the Trust Agreement, Securities generally will not be sold or replaced. The\nSponsor may, however, direct that Securities be sold in certain limited circumstances to protect a Portfolio based on advice from the\nSupervisor. These situations may include events such as the issuer having defaulted on payment of any of its outstanding obligations\nor the price or liquidity of a Security has

A-16

declined to such an extent or other credit factors exist so\nthat in the opinion of the Supervisor retention of the Security would be detrimental to a Portfolio. If a public tender offer has been\nmade for a Security or a merger, acquisition or other corporate action has been announced affecting a Security, the Trustee may either\nsell or tender the Security, or sell any security received as a result of the announced corporate action, if the Supervisor determines\nthat the sale or tender is in the best interest of Unitholders. The Trustee will distribute any cash proceeds to Unitholders unless the\nSponsor directs that such proceeds be reinvested in accordance with the Trust Agreement. In addition, the Trustee may sell Securities\nto redeem Units or pay Portfolio expenses or deferred sales charges. If securities or property are acquired by a Portfolio, the Sponsor\nmay direct the Trustee to sell the securities or property and distribute or reinvest the proceeds in accordance with the Trust Agreement\nor to accept the securities or property for deposit in the Portfolio. Should any contract for the purchase of any of the Securities fail,\nthe Sponsor will (unless substantially all of the moneys held in a Portfolio to cover the purchase are reinvested in substitute Securities\nin accordance with the Trust Agreement) refund the cash and sales charge attributable to the failed contract to all Unitholders on or\nbefore the next Distribution Date.

The Sponsor may direct the reinvestment\nof proceeds of the sale of Securities if the sale is the direct result of a decline in price or liquidity, or serious adverse credit\nfactors which, in the opinion of the Sponsor, would make retention of the Securities detrimental to a Portfolio. In such a case, the\nSponsor may, but is not obligated to, direct the reinvestment of sale proceeds in any other securities that meet the criteria for inclusion\nin a Portfolio on the Initial Date of Deposit. In certain other limited circumstances outlined in the Trust Agreement, including in connection\nwith certain tender offers, mergers, acquisitions, or other corporate actions, the Sponsor may also direct the reinvestment of sale proceeds\ninto the remaining Securities within your Portfolio. The Sponsor may also instruct the Trustee to take action necessary to ensure that\nyour Portfolio continues to satisfy the qualifications of a regulated investment company and to avoid imposition of tax on undistributed\nincome of the Portfolio.

When your Portfolio sells Securities, the\ncomposition and diversity of the Securities in the Portfolio may be altered. In order to obtain the best price for a Portfolio, it may\nbe necessary for the Supervisor to specify minimum amounts (generally 100 shares) in which blocks of Securities are to be sold. In effecting\npurchases and sales of Portfolio securities, the Sponsor may direct that orders be placed with and brokerage commissions be paid to brokers,\nincluding brokers which may be affiliated with your Portfolio, the Sponsor or dealers participating in the offering of Units.

Pursuant to an exemptive order, your Portfolio\nmay be permitted to sell Securities to a new trust when it terminates if those Securities are included in the new trust. The exemption\nmay enable your Portfolio to eliminate commission costs on these transactions. The price for those securities will be the closing sale\nprice on the sale date on the exchange where the Securities are principally traded, as certified by the Sponsor.

Amendment of the Trust Agreement. The\nTrustee and the Sponsor may amend the Trust Agreement without the consent of Unitholders to correct any provision which may be defective\nor to make other provisions that will not materially adversely affect Unitholders (as determined in good faith by the Sponsor and the\nTrustee). The Trust Agreement may not be amended to increase the number of Units or permit acquisition of securities in addition to or\nsubstitution for the Securities (except as provided in the Trust Agreement). The Trustee will notify Unitholders of any amendment.

Termination. Your Portfolio\nwill terminate on the Mandatory Termination Date specified under “Essential Information” or upon the sale or other disposition\nof the last Security held in the Portfolio. A Portfolio may be terminated at any time with consent of Unitholders representing two-thirds\nof the outstanding Units or by the Trustee when the value of the Portfolio is less than $500,000 ($3,000,000 if the value of the Portfolio\nhas exceeded $15,000,000) (the “Minimum Termination Value”). A Portfolio will be liquidated by the Trustee in the

A-17

event that a sufficient number of Units of the Portfolio not yet\nsold are tendered for redemption by the Sponsor, so that the net worth of the Portfolio would be reduced to less than 40% of the value\nof the Securities at the time they were deposited in the Portfolio. If your Portfolio is liquidated because of the redemption of unsold\nUnits by the Sponsor, the Sponsor will refund to each purchaser of Units the entire sales charge paid by such purchaser. The Trustee may\nbegin to sell Securities in connection with a Portfolio termination nine business days before, and no later than, the Mandatory Termination\nDate. Qualified Unitholders may elect an in kind distribution of Securities, provided that Unitholders may not request an in kind distribution\nof Securities within 30 calendar days of a Portfolio’s termination. Any in kind distribution of Securities will be made in the manner\nand subject to the restrictions described under “Rights of Unitholders--Redemption of Units”, provided that, in connection\nwith an in kind distribution election more than 30 calendar days prior to termination, Unitholders tendering 1,000 or more Units of a\nPortfolio (or such higher amount as may be required by your broker-dealer or selling agent) may request an in kind distribution of Securities\nequal to the Redemption Price per Unit on the date of tender. Unitholders will receive a final cash distribution within a reasonable time\nafter the Mandatory Termination Date. All distributions will be net of Portfolio expenses and costs. Unitholders will receive a final\ndistribution statement following termination. The Information Supplement contains further information regarding termination of your Portfolio.\nSee “Additional Information”.

Limitations on Liabilities. The\nSponsor, Evaluator, Supervisor and Trustee are under no liability for taking any action or for refraining from taking any action in good\nfaith pursuant to the Trust Agreement, or for errors in judgment, but shall be liable only for their own willful misfeasance, bad faith\nor gross negligence (negligence in the case of the Trustee) in the performance of their duties or by reason of their reckless disregard\nof their obligations and duties hereunder. The Trustee is not liable for depreciation or loss incurred by reason of the sale by the Trustee\nof any of the Securities. In the event of the failure of the Sponsor or Evaluator to act under the Trust Agreement, the Trustee may act\nthereunder and is not liable for any action taken by it in good faith under the Trust Agreement. The Trustee is not liable for any taxes\nor other governmental charges imposed on the Securities, on it as Trustee under the Trust Agreement or on a Portfolio which the Trustee\nmay be required to pay under any present or future law of the United States of America or of any other taxing authority having jurisdiction.\nIn addition, the Trust Agreement contains other customary provisions limiting the liability of the Trustee. The Sponsor and Supervisor\nmay rely on any evaluation furnished by the Evaluator and have no responsibility for the accuracy thereof. Determinations by the Trustee\nshall be made in good faith upon the basis of the best information available to it.

TAXATION

This section summarizes some of the principal\nU.S. federal income tax consequences of owning Units of the Portfolios. Tax laws and interpretations are subject to change, possibly with\nretroactive effect. This summary does not describe all of the tax consequences to all taxpayers. For example, this summary generally does\nnot describe your situation if you are a corporation, a non-U.S. person, a broker/dealer, a tax-exempt entity, financial institution,\nperson who marks to market their Units or other investor with special circumstances. In addition, this section does not describe your\nalternative minimum, state, local or foreign tax consequences of investing in the Portfolios.

This federal income tax summary is based in\npart on the advice of counsel to the Sponsor. The Internal Revenue Service could disagree with any conclusions set forth in this section.\nIn addition, our counsel was not asked to review the federal income tax treatment of the assets to be deposited in your Portfolio.

Additional information related to taxes is\ncontained in the Information Supplement. As with any investment, you should seek advice based on your individual circumstances from your\nown tax advisor.

Portfolio Status. Your Portfolio\nintends to elect and to qualify annually as a “regulated investment company” (\"RIC\") under the federal tax laws.\nIf your Portfolio qualifies under the tax law as a RIC and distributes its income in the manner and amounts required by the RIC tax requirements,\nthe Portfolio generally will not pay federal income taxes. But there is no assurance that the distributions made by your Portfolio will\neliminate all taxes for every year at the level of your Portfolio.

Distributions. Portfolio distributions\nare generally taxable. After the end of each year, you will receive a tax statement reporting your Portfolio's distributions, including\nthe amounts of ordinary income distributions and capital gains dividends. Your Portfolio may make taxable distributions to you even in\nperiods during which the value of your Units has declined. Ordinary income distributions are generally taxed at your federal tax rate\nfor ordinary income, however, as further discussed below, certain ordinary income distributions received from your Portfolio may be taxed,\nunder current federal law, at capital gains tax rates. Certain ordinary income dividends on Units that are attributable to qualifying\ndividends received by your Portfolio from certain corporations may be reported by the Portfolio as being eligible for the dividends received\ndeduction for corporate Unitholders provided certain holding period requirements are met. Income from a Portfolio and gains on the sale\nof your Units may also be subject to a 3.8% federal tax imposed on net investment income if your adjusted gross income exceeds certain\nthreshold amounts, which currently are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single\nindividuals. In addition, your Portfolio may make distributions that represent a return of capital for tax purposes to the extent of the\nUnitholder's basis in the Units, and any additional amounts in excess of basis would be taxed as a capital gain. Generally, you will treat\nall capital gains dividends as

A-19

long-term capital gains regardless of how long you have owned your\nUnits. The tax status of your distributions from your Portfolio is not affected by whether you reinvest your distributions in additional\nUnits or receive them in cash. The income from your Portfolio that you must take into account for federal income tax purposes is not reduced\nby amounts used to pay a deferred sales charge, if any. The tax laws may require you to treat certain distributions made to you in January\nas if you had received them on December 31 of the previous year.

A distribution paid by your Portfolio\ngenerally reduces the Portfolio's net asset value per Unit on the date paid by the amount of the distribution per Unit. If the price\nyou pay for Units reflects income or gains accumulated by the Portfolio before your purchase, a subsequent distribution of those amounts\nmay, in economic terms, represent a return of part of your investment. Nevertheless, distributions of taxable income or capital gains\ngenerally are subject to U.S. federal income tax to Unitholders holding Units in taxable accounts, whether received in cash or reinvested\nin additional Units, even when the distributed amounts were reflected in the purchase price.

Sale or Redemption of Units. If\nyou sell or redeem your Units, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you\nmust subtract your adjusted tax basis in your Units from the amount you receive for the sale of the Units. Your initial tax basis in your\nUnits is generally equal to the cost of your Units, generally including sales charges. In some cases, however, you may have to adjust\nyour tax basis after you purchase your Units.

Capital Gains and Losses and Certain\nOrdinary Income Dividends. Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable\nyear. 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\nfor the asset is one year or less. You must exclude the date you purchase your Units to determine your holding period. However, if you\nreceive a capital gain dividend from your Portfolio and sell your Units at a loss after holding it for six months or less, the loss will\nbe recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized\nfrom assets held for one year or less are generally the same as for ordinary income.

In certain circumstances, ordinary income\ndividends received by an individual Unitholder from a RIC such as your Portfolio may be taxed at the same federal rates that apply to\nnet capital gain (as discussed above), provided certain holding period requirements are satisfied and provided the dividends are attributable\nto qualified dividend income received by the Portfolio itself. Qualified dividend income means dividends paid to a Portfolio (a) by domestic\ncorporations, (b) by foreign corporations that are either (i) incorporated in a possession of the United States or (ii) are eligible for\nbenefits under certain income tax treaties with the United States that include an exchange of information program, or (c) with respect\nto stock of a foreign corporation that is readily tradeable on an established securities market in the United States. Both a Portfolio\nand the Unitholder must meet certain holding period requirements to qualify Portfolio dividends for this treatment. Income derived from\ninvestments in derivatives, fixed-income securities, U.S. real estate investment trusts, passive foreign investment companies, and income\nreceived \"in lieu of\" dividends in a securities lending transactions generally is not eligible for treatment as qualified dividend\nincome. If the qualified dividend income received by a Portfolio is equal to 95% (or a greater percentage) of the Portfolio's gross income\n(exclusive of net capital gain) in any taxable year, all of the ordinary income dividends paid by the Portfolio will be qualified dividend\nincome. Your Portfolio will provide notice to its Unitholders of the amount of any distribution which may be taken into account as qualified\ndividend income which is eligible for capital gains tax rates. There is no requirement that tax consequences be taken into account in\nadministering your Portfolio.

In Kind Distributions. Under\ncertain circumstances, as described in this prospectus, you may receive an in kind distribution of Portfolio securities when you redeem\nyour Units. In general, this distribution will be treated as a sale for federal income tax purposes and you will recognize gain or loss,\nbased on the value at that time of the securities and the amount of cash received, and subject to certain limitations on the deductibility\nof losses under the tax law.

A-20

Rollovers and Exchanges. If\nyou elect to have your proceeds from your Portfolio rolled over into a future trust, it would generally be considered a sale for federal\nincome tax purposes and any gain on the sale will be treated as a capital gain, and, in general, any loss will be treated as a capital\nloss. However, any loss realized on a sale or exchange will be disallowed to the extent that Units disposed of are replaced (including\nthrough reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after disposition of Units or\nto the extent that the Unitholder, during such period, acquires or enters into an option or contract to acquire, substantially identical\nstock or securities. In such a case, the basis of the Units acquired will be adjusted to reflect the disallowed loss. The deductibility\nof capital losses is subject to other limitations in the tax law.

Deductibility of Portfolio Expenses.\nExpenses incurred and deducted by your Portfolio will generally not be treated as taxable income to you. In certain cases if your\nPortfolio is not considered \"publicly offered\" under the Code, each U.S. Unitholder that is either an individual, trust or estate\nwill be treated as having received a taxable distribution from the Portfolio in the amount of that U.S. Unitholder's allocable share of\ncertain of the Portfolio's expenses for the calendar year, and these fees and expenses will be treated as miscellaneous itemized deductions\nof those U.S. Unitholders. Expenses that are characterized as miscellaneous itemized deductions, which include investment expenses, are\nnot deductible.

Foreign Investors. If you are\na foreign investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), generally,\nsubject to applicable tax treaties, distributions to you from your Portfolio will be characterized as dividends for federal income tax\npurposes (other than dividends that your Portfolio reports as capital gain dividends) and will be subject to U.S. income taxes, including\nwithholding taxes, subject to certain exceptions described below. You may be eligible under certain income tax treaties for a reduction\nin withholding rates. However, distributions received by a foreign investor from your Portfolio that are properly reported by the trust\nas capital gain dividends, interest-related dividends paid by the Portfolio from its qualified net interest income from U.S. sources and\nshort-term capital gain dividends, may not be subject to U.S. federal income taxes, including withholding taxes, provided that your Portfolio\nmakes certain elections and certain other conditions are met.

The Foreign Account Tax Compliance Act\n(\"FATCA\"). A 30% withholding tax on your Portfolio's distributions generally applies if paid to a foreign entity unless:\n(i) if the foreign entity is a \"foreign financial institution\" as defined under FATCA, the foreign entity undertakes certain\ndue diligence, reporting, withholding, and certification obligations, (ii) if the foreign entity is not a \"foreign financial institution,\"\nit identifies certain of its U.S. investors or (iii) the foreign entity is otherwise excepted under FATCA. If required under the rules\nabove and subject to the applicability of any intergovernmental agreements between the United States and the relevant foreign country,\nwithholding under FATCA may apply. Under existing regulations, FATCA withholding on gross proceeds from the sale of Units and capital\ngain distributions from your Portfolio took effect on January 1, 2019; however, recently proposed U.S. tax regulations eliminate FATCA\nwithholding on such types of payments. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations\nare issued. If withholding is required under FATCA on a payment related to your Units, investors that otherwise would not be subject to\nwithholding (or that otherwise would be entitled to a reduced rate of withholding) on such payment generally will be required to seek\na refund or credit from the IRS to obtain the benefit of such exemption or reduction. Your Portfolio will not pay any additional amounts\nin respect of amounts withheld under FATCA. You should consult your tax advisor regarding the effect of FATCA based on your individual\ncircumstances.

Foreign Tax Credit. If your\nPortfolio invests in any foreign securities, the tax statement that you receive may include an item showing foreign taxes your Portfolio\npaid to other countries. In this case, dividends taxed to you will include your share of the taxes your Portfolio paid to other countries.\nIf more than 50% of the value of a Portfolio's total assets at the end of a fiscal year is invested in foreign securities, the Portfolio\nmay elect to \"pass-through\" to the Unitholders the amount of foreign income tax paid by the

A-21

Portfolio in lieu of deducting such amount in determining its investment\ncompany taxable income. In such a case, Unitholders will be required (i) to include in gross income, even though not actually received,\ntheir respective pro rata shares of the foreign income tax paid by the Portfolio that are attributable to any distributions they receive;\nand (ii) either to deduct their pro rata share of foreign tax in computing their taxable income or to use it (subject to various limitations)\nas a foreign tax credit against federal income tax (but not both). No deduction for foreign tax may be claimed by a non-corporate Unitholder\nwho does not itemize deductions or who is subject to the alternative minimum tax. Unitholders may be unable to claim a credit for the\nfull amount of their proportionate shares of the foreign income tax paid by a Portfolio due to certain limitations that may apply. The\nPortfolios reserve the right not to pass-through to its Unitholders the amount of foreign income taxes paid by a Portfolio.

Backup Withholding. By law,\nyour Portfolio must withhold as backup withholding a percentage (currently 24%) of your taxable distributions and redemption proceeds\nif you do not provide your correct social security or taxpayer identification number and certify that you are not subject to backup withholding,\nor if the IRS instructs your Portfolio to do so.

Investors should consult their advisors concerning\nthe federal, state, local and foreign tax consequences of investing in the Portfolio.

PORTFOLIO OPERATING EXPENSES

General. The fees and expenses\nof your Portfolio will generally accrue on a daily basis. Portfolio operating fees and expenses are generally paid out of the Income Account\nto the extent funds are available, and then from the Capital Account. The deferred sales charge, creation and development fee and organization\ncosts are generally paid out of the Capital Account of your Portfolio. It is expected that Securities will be sold to pay these amounts\nwhich will result in capital gains or losses to Unitholders. See “Taxation”. These sales will reduce future income distributions.\nThe Sponsor’s, Supervisor’s and Trustee’s fees may be increased without approval of the Unitholders by amounts not exceeding\nproportionate increases under the category “Services Less Rent of Shelter” in the Consumer Price Index for All Urban Consumers\nor, if this category is not published, in a comparable category.

Organization Costs. You and\nthe other Unitholders will bear all or a portion of the organization costs and charges incurred in connection with the establishment of\nyour Portfolio. These costs and charges will include the cost of the preparation, printing and execution of the trust agreement, registration\nstatement and other documents relating to your Portfolio, federal and state registration fees and costs, the initial fees and expenses\nof the Trustee, and legal and auditing expenses. The Public Offering Price of Units includes the estimated amount of these costs. The\nTrustee will deduct these expenses from your Portfolio’s assets at the end of the initial offering period.

Creation and Development Fee. The\nSponsor will receive a fee from your Portfolio for creating and developing the Portfolio, including determining the Portfolio’s\nobjectives, policies, composition and size, selecting service providers and information services and for providing other similar administrative\nand ministerial functions. The creation and development fee is a charge of $0.05 per Unit. The Trustee will deduct this amount from your\nPortfolio’s assets as of the close of the initial offering period. No portion of this fee is applied to the payment of distribution\nexpenses or as compensation for sales efforts. This fee will not be deducted from proceeds received upon a repurchase, redemption or exchange\nof Units before the close of the initial public offering period.

Trustee’s Fee. For its\nservices the Trustee will receive the fee from your Portfolio set forth in the “Fee Table” (which includes the estimated amount\nof miscellaneous Portfolio expenses). The Trustee benefits to the extent there are funds in the Capital and Income Accounts since these\nAccounts are non-interest bearing to Unitholders and the amounts earned by the Trustee are retained by the Trustee. Part of the Trustee’s\ncompensation for its services to your Portfolio is expected to result from the use of these funds.

Compensation of Sponsor and Supervisor.\nThe Sponsor and the Supervisor, which is an affiliate of the Sponsor, will receive the annual fees for providing bookkeeping and\nadministrative services and portfolio

A-22

supervisory services set forth in the “Fee Table”.\nThese fees may exceed the actual costs of providing these services to your Portfolio but at no time will the total amount received for\nthese services rendered to all Invesco unit investment trusts in any calendar year exceed the aggregate cost of providing these services\nin that year.

Miscellaneous Expenses. The\nfollowing additional charges are or may be incurred by your Portfolio: (a) normal expenses (including the cost of mailing reports to Unitholders)\nincurred in connection with the operation of the Portfolio, (b) fees of the Trustee for extraordinary services, (c) expenses of the Trustee\n(including legal and auditing expenses) and of counsel designated by the Sponsor, (d) various governmental charges, (e) expenses and costs\nof any action taken by the Trustee to protect the Portfolio and the rights and interests of Unitholders, (f) indemnification of the Trustee\nfor any loss, liability or expenses incurred in the administration of the Portfolio without negligence, bad faith or willful misconduct\non its part, (g) foreign custodial and transaction fees (which may include compensation paid to the Trustee or its subsidiaries or affiliates),\n(h) costs associated with liquidating the securities held in the Portfolio, (i) any offering costs incurred after the end of the initial\noffering period and (j) expenditures incurred in contacting Unitholders upon termination of the Portfolio. Your Portfolio may pay the\nexpenses of updating its registration statement each year. The Dividend Sustainability Portfolio and the Global Dividend Sustainability\nPortfolio will each pay a license fee to S&P Opco, LLC for the use of certain trademarks and other property.

RISK FACTORS

Price Volatility. Each Portfolio\ninvests in securities of U.S. and foreign companies, you should understand the risks of investing in securities before purchasing Units.\nThese risks include the risk that the financial condition of the company or the general condition of the securities markets may worsen\nand the value of the securities (and therefore Units) will fall. Securities are especially susceptible to general market movements. The\nvalue of securities often rises or falls rapidly and unpredictably as market confidence and perceptions of companies change. These perceptions\nare based on factors including expectations regarding government economic policies, inflation, interest rates, economic expansion or contraction,\npolitical climates and economic or banking crises. The value of Units will fluctuate with the value of the securities in a Portfolio and\nmay be more or less than the price you originally paid for your Units. As with any investment, we cannot guarantee that the performance\nof a Portfolio will be positive over any period of time. Because the Portfolios are unmanaged, the Trustee will not sell securities in\nresponse to market fluctuations as is common in managed investments.

Dividends. Stocks represent\nownership interests in a company and are not obligations of the company. Common stockholders have a right to receive payments from the\ncompany that is subordinate to the rights of creditors, bondholders or preferred stockholders of the company. This means that common stockholders\nhave a right to receive dividends only if a company’s board of directors declares a dividend and the company has provided for payment\nof all of its creditors, bondholders and preferred stockholders. If a company issues additional debt securities or preferred stock, the\nowners of these securities will have a claim against the company’s assets before common stockholders if the company declares bankruptcy\nor liquidates its assets even though the common stock was issued first. As a result, the company may be less willing or able to declare\nor pay dividends on its common stock.

Foreign Stocks. Because certain\nPortfolios invest in foreign stocks, these Portfolios involve additional risks that differ from an investment in domestic stocks. Investments\nin foreign securities may involve a greater degree of risk than those in domestic securities. There is generally less publicly available\ninformation about foreign companies in the form of reports and ratings similar to those that are published about issuers in the United\nStates. Also, foreign issuers are generally not subject to uniform accounting, auditing and financial reporting requirements comparable\nto those applicable to United States issuers. With respect to certain foreign countries, there is the possibility of adverse changes in\ninvestment or exchange control regulations, expropriation, nationalization or confiscatory taxation, limitations on the removal of funds\nor other assets of a Portfolio, political or social instability, or diplomatic developments which could affect United States investments\nin those countries. Moreover, industrial foreign economies may differ favorably or unfavorably from the United States’ economy in\nterms of growth of gross national product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payments\nposition.

Foreign Currencies. Certain\nPortfolios also involve the risk that fluctuations in exchange rates between the U.S. dollar and foreign currencies may negatively affect\nthe 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,\na U.S. investor’s return would be reduced to about 5%. This is because the foreign currency would “buy” fewer dollars\nor, conversely, a dollar would buy more of the foreign currency. Many foreign currencies have fluctuated widely against the U.S. dollar\nfor a variety of reasons such as supply and demand of the currency, investor perceptions of world or country economies, political instability,\ncurrency speculation by institutional investors, changes in government policies, buying and selling of currencies by central banks of\ncountries, trade balances and changes in interest rates.

Liquidity. Whether or not the\nstocks in a Portfolio are listed on a stock exchange, the stocks may delist from the exchange or principally trade in an over-the-counter\nmarket. As a result, the existence of a liquid trading market could depend on whether dealers will make a market in the stocks. We cannot\nguarantee that dealers will maintain a market or that any market will be liquid. The value of the stocks could fall if trading markets\nare limited or absent.

Additional Units. The Sponsor\nmay create additional Units of a Portfolio by depositing into the Portfolio additional stocks or cash with instructions to purchase additional\nstocks. A deposit could result in a dilution of your investment and anticipated income because of fluctuations in the price of the stocks\nbetween the time of the deposit and the purchase of the stocks and because a Portfolio will pay brokerage or acquisition fees.

Voting. Only the Trustee may\nsell or vote the stocks in a Portfolio. While you may sell or redeem your Units, you may not sell or vote the stocks in your Portfolio.\nThe Sponsor will instruct the Trustee how to vote the stocks. The Trustee will vote the stocks in the same general proportion as shares\nheld by other shareholders if the Sponsor fails to provide instructions.

TAXATION

The prospectus contains a discussion of certain\nU.S. federal income tax issues concerning the Portfolios and the purchase, ownership and disposition of Portfolio Units. The discussion\nbelow supplements the prospectus discussion and is qualified in its entirety by the prospectus discussion. Prospective investors should\nconsult their own tax advisors with regard to the federal tax consequences of the purchase, ownership, or disposition of Portfolio Units,\nas well as the tax consequences arising under the laws of any state, locality, non-U.S. country, or other taxing jurisdiction.

This federal income tax summary is based in\npart on the advice of counsel to the Sponsor. The Internal Revenue Service could disagree with any conclusions set forth in this section.\nIn addition, our counsel was not asked to review and has not reached a conclusion with respect to the federal income tax treatment of\nthe assets to be deposited in your Portfolio.

The Portfolios intend to elect and to qualify\nannually as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”), and to comply\nwith applicable distribution requirements so that it will not pay federal income tax on income and capital gains distributed to its Unitholders.

To qualify for the favorable U.S. federal\nincome tax treatment generally accorded to regulated investment companies, a Portfolio must, among other things, (a) derive in each taxable\nyear at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other\ndisposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock,\nsecurities or currencies, and net income from qualified publicly traded partnerships; (b) diversify its holdings so that, at the end of\neach quarter of the taxable year, (i) at least 50% of the market value of the Portfolio’s assets is represented by cash and cash\nitems (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities,\nwith such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of\nthe value of the Portfolio’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii)\nnot more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities\nof other regulated investment companies) of any one issuer, or two or more issuers which the Portfolio controls (by owning 20% or more\nof the issuer’s outstanding voting securities) and which are engaged in

the same, similar or related trades or businesses, or the securities\nof qualified publicly traded partnerships; and (c) distribute at least 90% of its investment company taxable income (which includes, among\nother items, dividends, interest and net short-term capital gains in excess of net long-term capital losses but excludes net capital gain,\nif any) and at least 90% of its net tax-exempt interest income, if any, each taxable year.

As a regulated investment company, your Portfolio\ngenerally will not be subject to U.S. federal income tax on its investment company taxable income (as that term is defined in the Code,\nbut without regard to the deduction for dividends paid) and net capital gain (the excess of net long-term capital gain over net short-term\ncapital loss), if any, that it distributes to Unitholders. Your Portfolio intends to distribute to its Unitholders, at least annually,\nsubstantially all of its investment company taxable income and net capital gain. If a Portfolio retains any net capital gain or investment\ncompany taxable income, it will generally be subject to federal income tax at regular corporate rates on the amount retained. In addition,\namounts not distributed on a timely basis in accordance with a calendar year distribution requirement are subject to a nondeductible 4%\nexcise tax unless, generally, a Portfolio distributes during each calendar year an amount equal to the sum of (1) at least 98% of its\nordinary income (not taking into account any capital gains or losses) for the calendar year, (2) at least 98.2% of its capital gains in\nexcess of its capital losses (adjusted for certain ordinary losses) for the one-year period ending October 31 of the calendar year, and\n(3) any ordinary income and capital gains for previous years that were not distributed or taxed during those years. To prevent application\nof the excise tax, your Portfolio intends to make its distributions in accordance with the calendar year distribution requirement. Further,\nif a Portfolio retains any net capital gain, the Portfolio may designate the retained amount as undistributed capital gains in a notice\nto Unitholders who, if subject to federal income tax on long-term capital gains (i) will be required to include in income for federal\nincome tax purposes, as long-term capital gain, their share of such undistributed amount, and (ii) will be entitled to credit their proportionate\nshare of the tax paid by the Portfolio against their federal income tax liabilities, if any, and to claim refunds to the extent the credit\nexceeds such liabilities. A distribution will be treated as paid on December 31 of the current calendar year if it is declared by a Portfolio\nin October, November or December with a record date in such a month and paid by the Portfolio during January of the following calendar\nyear. These distributions will be taxable to Unitholders in the calendar year in which the distributions are declared, rather than the\ncalendar year in which the distributions are received. There is no assurance that distributions made by your Portfolio will be sufficient\nto eliminate all taxes on the Trust for all periods. Your Portfolio may make taxable distributions to you even during periods in which\nthe value of your Units has declined.

If a Portfolio failed to qualify as a regulated\ninvestment company or failed to satisfy the 90% distribution requirement in any taxable year, the Portfolio would be taxed as an ordinary\ncorporation on its taxable income (even if such income were distributed to its Unitholders) and all distributions out of earnings and\nprofits would be taxable to Unitholders as ordinary dividend income, although corporate Unitholders could be eligible for the dividends\nreceived deduction (subject to certain limitations) and non-corporate Unitholders may be able to benefit from the lower tax rates available\nto qualified dividend income.

Your Portfolio may be required to withhold\nas backup withholding federal income tax at the backup withholding rate on all taxable distributions payable to you if you fail to provide\nyour correct taxpayer identification number or to make required certifications, or if the IRS indicates that you are subject to backup\nwithholding. Backup withholding is not an additional tax. Any amounts withheld may be credited against your federal income tax liability\nif you provide the required information or certification.

If a Portfolio is treated as holding directly\nor indirectly 10 percent or more of the combined value or voting power of the stock of a foreign corporation, and all U.S. shareholders\ncollectively own more than 50 percent of the vote or value of the stock of such corporation, the foreign corporation may be treated as\na “controlled foreign corporation” (a “CFC”) for U.S. federal income tax purposes. In such circumstances, a Portfolio\nwill be required to include certain types of passive income and

certain other types of income relating to insurance, sales and\nservices with related parties and oil related income in the Portfolio’s taxable income whether or not such income is distributed.

If a Portfolio holds an equity interest in\nany “passive foreign investment companies” (“PFICs”), which are generally certain foreign corporations that receive\nat least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains)\nor that hold at least 50% of their assets in investments producing such passive income, the Portfolio could be subject to U.S. federal\nincome tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the\nincome or gain is timely distributed to its Unitholders. A Portfolio will not be able to pass through to its Unitholders any credit or\ndeduction for such taxes. A Portfolio may be able to make an election that could ameliorate these adverse tax consequences. In this case,\na Portfolio would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such\nvalue to the extent it did not exceed prior increases included in income. Under this election, a Portfolio might be required to recognize\nin a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such\nincome would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax\n(described above). Dividends paid by PFICs will not be treated as qualified dividend income.

PORTFOLIO TERMINATION

A Portfolio may be liquidated at any time\nby consent of Unitholders representing 66 2/3% of the Units of such Portfolio then outstanding or by the Trustee when the value of the\nSecurities owned by a Portfolio, as shown by any evaluation, is less than $500,000 ($3,000,000 if the value of a Portfolio has exceeded\n$15,000,000). A Portfolio will be liquidated by the Trustee in the event that a sufficient number of Units of such Portfolio not yet sold\nare tendered for redemption by the Sponsor, so that the net worth of such Portfolio would be reduced to less than 40% of the value of\nthe Securities at the time they were deposited in such Portfolio. If a Portfolio is liquidated because of the redemption of unsold Units\nby the Sponsor, the Sponsor will refund to each purchaser of Units the entire sales charge paid by such purchaser. The Trust Agreement\nwill terminate upon the sale or other disposition of the last Security held thereunder, but in no event will it continue beyond the Mandatory\nTermination Date.

Commencing during the period beginning nine\nbusiness days prior to, and no later than, the Mandatory Termination Date, Securities will begin to be sold in connection with the termination\nof the Portfolios. The Sponsor will determine the manner, timing and execution of the sales of the Securities. The Sponsor shall direct\nthe liquidation of the Securities in such manner as to effectuate orderly sales and a minimal market impact. In the event the Sponsor\ndoes not so direct, the Securities shall be sold within a reasonable period and in such manner as the Trustee, in its sole discretion,\nshall determine. Unitholders will receive a cash distribution from the sale of the remaining Securities within a reasonable time following\nthe Mandatory Termination Date. The Trustee will deduct from the funds of the appropriate Portfolio any accrued costs, expenses, advances\nor indemnities provided by the Trust Agreement, including estimated compensation of the Trustee, costs of liquidation and any amounts\nrequired as a reserve to provide for payment of any applicable taxes or other governmental charges. Any sale of Securities in a Portfolio\nupon termination may result in a lower amount than might otherwise be realized if such sale were not required at such time. The Trustee\nwill then distribute to each Unitholder of each Portfolio his pro rata share of the balance of the Income and Capital Accounts of such\nPortfolio.

The Sponsor may, but is not obligated to,\noffer for sale units of a subsequent series of the Portfolios. There is, however, no assurance that units of any new series of the Portfolios\nwill 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\nor all Unitholders.

Within 60 days of the final distribution Unitholders\nwill be furnished a final distribution statement of the amount distributable. At such time as the Trustee in its sole discretion will\ndetermine that any amounts held in reserve

are no longer necessary, it will make distribution thereof to Unitholders\nin the same manner.

Subject to the terms and conditions of\nSection 15(d) of the Securities Exchange Act of 1934, the undersigned registrant hereby undertakes to file with the Securities and Exchange\nCommission such supplementary and periodic information, documents, and reports as may be prescribed by any rule or regulation of the Commission\nheretofore or hereafter duly adopted pursuant to authority conferred in that section.

Undertaking\nRegarding Indemnification

Insofar as indemnification\nfor liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant\npursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange\nCommission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a\nclaim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director,\nofficer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director,\nofficer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel\nthe matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification\nby it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
