Investment Objective. The Portfolio seeks toprovide capital appreciation.

Principal Investment Strategy. The Portfolioseeks to achieve its objective by investing in a portfolioprimarily consisting of stocks of companies in thetechnology industry that have a global presence. Thetechnology industry may be categorized intocommunication equipment, computers & peripherals,electronic equipment instruments & components, ITservices, internet software & services, semiconductors& equipment and software companies. Invesco CapitalMarkets, Inc., the Sponsor, constructs the Portfolio totake advantage of potential opportunities within thetechnology industry based on its current outlook oncontinually evolving industry paradigms. The Portfoliomay represent an attractive alternative for investorschoosing to have a port ion of their portfol iorepresented in the information technology sector,which currently represents approximately 28% of theStandard & Poor’s 500 Index in terms of market value.

Rather than focus on part icu lar sectors orsub-sectors, the Sponsor takes a holistic view of thetechnology industry and chooses to focus primarilyon those companies with disruptive technologiesparticipating in markets tied to particular secularthemes. These secular themes may include: 5G,artificial intelligence (“AI”), cloud infrastructure andservices, cybersecurity, data analytics, f intech,internet of things (“IoT”), and remote working andlearn ing. A key cr i ter ion in stock se lect ion,regardless of theme or technology, was askingwhere the world is going and how certain companiesare participating in this movement.

The companies selected for the Portfolio mayshare a variety of traits, among others, as of the timeof selection, such as:

• Secularly-focused business model targetingat least one of the identified themes

• Disruptive technology

• Revenue & earnings-per-share (EPS) growthopportunities

• Company-specific gross margin expansioncatalysts

• A history of achieving strong financial results

As with any investment, no one can guaranteethat your Portfolio will achieve its objective. Thevalue of your Units may fall below the price you paidfor the Units. Stocks of technology companies havebeen subject to extreme pr ice volat i l i ty andspeculative trading. The Portfolio is appropriate foraggressive investors or as an aggressive growthcomponent of an investment portfolio. You shouldread the “Risk Factors” section before you invest.

The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achievemore consistent overall results by following thestrategy through reinvestment of your proceeds overseveral years if subsequent series are available.Repeatedly rol l ing over an investment in a unitinvestment trust may differ from long-term investmentsin other investment products when considering thesales charges, fees, expenses and tax consequencesattributable to a Unitholder. For more information see“Rights of Unitholders--Rollover”.

Principal Risks. As with all investments, youcan lose money by investing in this Portfolio. ThePortfolio also might not perform as well as youexpect. This can happen for reasons such as these:

Example

This example helps you compare the cost of the Portfolio with otherunit trusts and mutual funds. In the example we assume that theexpenses do not change and that the Portfolio’s annual return is 5%. Youractual returns and expenses will vary. This example also assumes thatyou continue to follow the Portfolio strategy and roll your investment,including all distributions, into a new trust each year subject to a salescharge of 1.85%. Based on these assumptions, you would pay thefollowing expenses for every $10,000 you invest in the Portfolio:

1 year $ 245 3 years 753 5 years 1,286 10 years 2,736

* The estimated annual expenses are based upon the estimated trust sizefor the Portfolio determined as of the initial date of deposit. Becausecertain of the operating expenses are fixed amounts, if the Portfolio doesnot reach the estimated size, or if the value of the Portfolio or number ofoutstanding units decline over the life of the trust, or if the actual amountof the operating expenses exceeds the estimated amounts, the actualamount of the operating expenses per 100 units would exceed theestimated amounts. In some cases, the actual amount of operatingexpenses may substantially differ from the amounts reflected above.

The maximum sales charge is 1.85% of the Public Offering Priceper Unit. There is no initial sales charge at a Public Offering Price of $10or less. If the Public Offering Price exceeds $10 per Unit, the initial salescharge is the difference between the total sales charge (maximum of1.85% of the Public Offering Price) and the sum of the remainingdeferred sales charge and the creation and development fee. Thedeferred sales charge is fixed at $0.135 per Unit and accrues daily fromJanuary 10, 2022 through June 9, 2022. Your Portfolio pays aproportionate amount of this charge on the 10th day of each monthbeginning in the accrual period until paid in full. The combination of theinitial and deferred sales charges comprises the “transactional salescharge”. The creation and development fee is fixed at $0.05 per Unitand is paid at the earlier of the end of the initial offering period(anticipated to be three months) or six months following the Initial Dateof Deposit. For more detail, see “Public Offering Price—General.”

Investment Objective. The Portfolio seeks toprovide the potential for above-average capitalappreciation.

Principal Investment Strategy. The Portfolioseeks to achieve its objective by investing in commonstocks of domestic aerospace and defense relatedcompanies that derive a meaningful portion of theirrevenue from the U.S. Government’s Department ofDefense. The aerospace and defense industriestypically include companies engaged in the productionof aircraft, maritime ships, military equipment, such astanks and related vehicles, bombs, missi les,associated navigational and guidance systems,artillery, ammunition, as well as cybersecurity.

In selecting the securities for the Portfolio, InvescoCapital Markets, Inc., the Sponsor, initially consideredthe universe of aerospace and defense relatedcompanies. After eliminating companies from this setwith a share price below $5, the Sponsor identifiedstocks of aerospace and defense companies thatderive a meaningful portion of revenue from the U.S.Government’s Department of Defense.

The Sponsor assembled the final portfolio ofaerospace and defense stocks based on considerationof additional factors, including, but not limited to:

• Valuation – Companies whose currentvaluations appear attractive relative to long-term trends.

• Growth – Companies with a history of andprospects for above-average growth of salesand earnings.

• Cash Flow Generation – Companies with ahistory of generating attractive operating andfree cash flows.

• Balance Sheet – Companies displayingbalance sheet strength evidenced by a historyof achieving strong financial results and makingdisciplined capital management decisions.

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


The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achieve moreconsistent overall results by following the strategythrough reinvestment of your proceeds over severalyears if subsequent series are available. Repeatedlyrolling over an investment in a unit investment trust maydiffer from long-term investments in other investmentproducts when considering the sales charges, fees,expenses and tax consequences attributable to aUnitholder. For more information see “Rights ofUnitholders--Rollover”.




• The financial condition of an issuer mayworsen or its credit ratings may drop,resulting in a reduction in the value ofyour Units. This may occur at any point intime, including during the initial offering period.

• The Portfolio invests exclusively incompanies operating in the aerospaceand defense industries, resulting in aconcentration in the industrialsindustry. As discussed further under “RiskFactors - Industry Risks” risks of aerospaceand defense companies include f iercecompetition, consolidation, adverse politicaland government developments, substantialresearch and development costs, l imitednumbers of potential customers and excesscapacity and spending trends. Further,companies in the industrials industry face riskssuch as general state of the economy, intensecompetition, imposition of import controls,volat i l i ty in commodity prices, currencyexchange rate fluctuation, consolidation, laborrelations, domestic and international politics,excess capacity, and consumer spendingtrends. Negative developments in theaerospace and defense industries and theindustrials industry will affect the value of yourinvestment more than would be the case in amore diversified investment.

• The Portfolio invests in stocks of smallercapitalization companies. These stocks areoften more volatile and have lower tradingvolumes than stocks of larger companies.Smaller capitalization companies may havelimited products or f inancial resources,management inexperience and less publiclyavailable information.

Opinion on the Financial Statements

We have audited the accompanying statements of condition (including the related portfolio schedules) ofGlobal Technology Leaders Portfolio 2021-4; American Innovation Leaders Portfolio 2021-3; New World LeadersPortfolio 2021-3; and U.S. Defense Portfolio 2021-3 (included in Invesco Unit Trusts, Series 2160 (the “Trust”)) asof September 13, 2021, and the related notes (collectively referred to as the “financial statements”). In ouropinion, the financial statements present fairly, in all material respects, the financial position of the Trust as of September 13, 2021, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

Our audits included performing procedures to assess the risks of material misstatement of the financialstatements, whether due to error or fraud, and performing procedures that respond to those risks. Suchprocedures included examining, on a test basis, evidence regarding the amounts and disclosures in thefinancial statements. Our audits also included evaluating the accounting principles used and significantestimates made by the Sponsor, as well as evaluating the overall presentation of the financial statements. Ourprocedures included confirmation of cash or irrevocable letters of credit deposited for the purchase ofsecurities as shown in the statements of condition as of September 13, 2021 by correspondence with TheBank of New York Mellon, Trustee.

(1) The value of the Securities is determined by the Trustee on the bases set forth under “Public Offering--Unit Price”. The contracts to purchaseSecurities 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 aPortfolio. The amount of these costs are set forth in the “Fee Table”. A distribution will be made as of the earlier of the close of the initialoffering period (approximately three months) or six months following the Initial Date of Deposit to an account maintained by the Trustee fromwhich the organization expense obligation of the investors will be satisfied. To the extent that actual organization costs of a Portfolio aregreater than the estimated amount, only the estimated organization costs added to the Public Offering Price will be reimbursed to theSponsor 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 of theinitial offering period. If Units are redeemed prior to the close of the initial public offering period, the fee will not be deducted from 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 of theState of New York pursuant to a Trust Indenture andTrust Agreement (the “Trust Agreement”), dated thedate of this prospectus (the “Initial Date of Deposit”),among Invesco Capital Markets, Inc., as Sponsor,Invesco Investment Advisers LLC as Supervisor, andThe Bank of New York Mellon, as Trustee.

The Portfolios offer investors the opportunity topurchase Units representing proportionate interests inportfolios of securities. Each Portfolio may be anappropriate medium for investors who desire toparticipate in a portfolio of securities with greaterdiversification than they might be able to acquireindividually.

On the Initial Date of Deposit, the Sponsor depositeddelivery statements relating to contracts for thepurchase of the Securities and an irrevocable letter ofcredit in the amount required for these purchases withthe Trustee. In exchange for these contracts, theTrustee delivered to the Sponsor documentationevidencing the ownership of Units of the Portfolios.Unless otherwise terminated as provided in the TrustAgreement, the Portfol ios wi l l terminate on theMandatory Termination Date and any remainingSecurities will be liquidated or distributed by the Trusteewithin a reasonable time. As used in this prospectus theterm “Securities” means the securities (includingcontracts to purchase these securities) listed in each“Portfolio” and any additional securities deposited intoeach Portfolio.

Additional Units of a Portfolio may be issued at anytime by deposit ing in the Portfol io ( i ) addit ionalSecurities, (ii) contracts to purchase Securities togetherwith cash or irrevocable letters of credit or (iii) cash (or aletter of credit or the equivalent) with instructions topurchase additional Securities. As additional Units areissued by a Portfolio, the aggregate value of theSecurities will be increased and the fractional undividedinterest represented by each Unit may be decreased.The Sponsor may continue to make additional depositsinto a Portfolio following the Initial Date of Depositprovided that the additional deposits will be in amounts

which will maintain, as nearly as practicable, the samepercentage relationship among the number of shares ofeach Security in the Portfolio that existed immediatelyprior to the subsequent deposit. Investors mayexperience a dilution of their investments and areduction in their anticipated income because offluctuations in the prices of the Securities between thetime of the deposit and the purchase of the Securitiesand because the Portfolios will pay the associatedbrokerage or acquisition fees. In addition, during theinitial offering of Units it may not be possible to buy apart icular Security due to regulatory or tradingrestrictions, or corporate actions. While such limitationsare in effect, additional Units would be created bypurchasing each of the Securities in your Portfolio thatare not subject to those limitations. This would alsoresult in the dilution of the investment in any suchSecurity not purchased and potential variances inanticipated income. Purchases and sales of Securitiesby your Portfolio may impact the value of the Securities.This may especially be the case during the initial offeringof Units, upon Portfolio termination and in the course ofsatisfying large Unit redemptions.

Each Unit of your Portfolio initially offered representsan undivided interest in the Portfolio. At the close of theNew York Stock Exchange on the Init ial Date ofDeposit, the number of Units may be adjusted so thatthe Public Offering Price per Unit equals $10. Thenumber of Units, fractional interest of each Unit in yourPortfolio and the per Unit amount of historical annualdistributions will increase or decrease to the extent ofany adjustment. To the extent that any Units areredeemed to the Trustee or additional Units are issuedas a result of additional Securities being deposited bythe Sponsor, the fractional undivided interest in yourPortfolio represented by each unredeemed Unit willincrease or decrease accordingly, although the actualinterest in your Portfolio will remain unchanged. Unitswill remain outstanding until redeemed upon tender tothe Trustee by Unitholders, which may include theSponsor, or until the termination of the Trust Agreement.

Each Portfolio consists of (a) the Securities (includingcontracts for the purchase thereof) listed under theapplicable “Portfolio” as may continue to be held from

A-2

time to time in the Portfolio, (b) any additional Securitiesacquired and held by the Portfolio pursuant to theprovisions of the Trust Agreement and (c) any cash heldin the related Income and Capital Accounts. Neither theSponsor nor the Trustee shall be liable in any way forany contract failure in any of the Securities.

OBJECTIVES AND SECURITIES SELECTION

The objective of each Portfolio is described in theindividual Portfolio sections. There is no assurance thata Portfolio will achieve its objective.

The Sponsor does not manage the Portfolios. Youshould note that the Sponsor applied the selectioncriteria to the Securities for inclusion in the Portfoliosprior to the Initial Date of Deposit. After this time, theSecurities may no longer meet the selection criteria.Should a Security no longer meet the selection criteria,we will generally not remove the Security from aPortfolio. In offering the Units to the public, neither theSponsor nor any broker-dealers are recommending anyof the individual Securities but rather the entire pool ofSecurities in a Portfolio, taken as a whole, which arerepresented by the Units.

RISK FACTORS

All investments involve risk. This section describesthe main r isks that can impact the value of thesecurities in the Portfolios. You should understandthese risks before you invest. If the value of thesecurities falls, the value of your Units will also fall. Wecannot guarantee that your Portfolio will achieve itsobjective or that your investment return will be positiveover any period.

Market Risk. Market risk is the risk that the valueof the securities in your Portfolio will fluctuate. Thiscould cause the value of your Units to fall below youroriginal purchase price. Market value fluctuates inresponse to various factors. These can includechanges in interest rates, inflation, the financialcondition of a security’s issuer, perceptions of theissuer, or ratings on a security of the issuer. Certaingeopolitical and other events, including environmentalevents and public health events such as epidemics and

pandemics, may have a global impact and add toinstability in world economies and markets generally.Changing economic, political or financial marketconditions in one country or geographic region couldadversely affect the market value of the securities heldby your Portfolio in a different country or geographicregion due to increasingly interconnected globaleconomies and financial markets. Even though yourPortfolio is supervised, you should remember that wedo not manage your Portfolio. Your Portfolio will not sella security solely because the market value falls as ispossible in a managed fund. In addition, because theU.S. Defense Portfolio holds a relatively small numberof stocks, you may encounter more price volatility thanwould occur in an investment diversified among agreater number of stocks.

Furthermore, a recent outbreak of a respiratorydisease caused by a novel coronavirus (“COVID-19”),first detected in China in December 2019, has spreadglobally in a short period of time. COVID-19 has resultedin the disruption of, and delays in, production and supplychains and the delivery of healthcare services andprocesses, as well as the cancellation of organizedevents and educational institutions, a decline inconsumer demand for certain goods and services, andgeneral concern and uncertainty. In response,governments and businesses world-wide, including theUnited States, have taken aggressive measures,including closing borders, restricting international anddomestic travel, and imposing prolonged quarantines oflarge populations, and financial support of the economyand financial markets. COVID-19 and its effects havecontributed to increased volatility in global markets,severe losses, liquidity constraints, and lowered yields;the duration of such effects cannot yet be determinedbut could be present for an extended period of time. Theeffects that COVID-19 may have on certain sectors andindustries are uncertain and may adversely affect thevalue of your Portfolio.

Dividend Payment Risk. Dividend payment risk isthe risk that an issuer of a security is unwilling orunable to pay dividends on a security. Stocks representownership interests in the issuers and are notobligations of the issuers. Common stockholders have

a right to receive dividends only after the company hasprovided for payment of its creditors, bondholders andpreferred stockholders. Common stocks do not assuredividend payments. Dividends are paid only whendeclared by an issuer’s board of directors and theamount of any div idend may vary over t ime. I fdividends received by your Portfolio are insufficient tocover expenses, redemptions or other Portfolio costs,it may be necessary for the Portfolio to sell Securitiesto cover such expenses, redemptions or other costs.Any such sales may result in capital gains or losses toyou. See “Taxation”.

Smaller Capitalization Companies. The U.S.Defense Portfolio invests significantly in stocks ofsmall capitalization and mid capitalization (collectively“smaller cap”) companies. Investing in stocks ofsmaller cap companies may involve greater risk thaninvesting in stocks of larger capitalization companies,since they can be subject to more abrupt or erraticprice movements. Many smaller cap companies willhave had their securities publicly traded, if at all, foronly a short period of time and will not have had theopportunity to establish a reliable trading patternthrough economic cycles. The price volatility of smallercap companies is relatively higher than larger, olderand more mature companies. This greater pricevolatility of smaller cap companies may result from thefact that there may be less market liquidity, lessinformation publicly available or fewer investors whomonitor the activities of these companies. In addition,the market prices of these securities may exhibit moresensitivity to changes in industry or general economicconditions. Some smaller cap companies will not havebeen in existence long enough to exper ienceeconomic cycles or to demonstrate whether they aresufficiently well managed to survive downturns orinflationary periods. Further, a variety of factors mayaffect the success of a company's business beyondthe abi l i ty of i ts management to prepare orcompensate for them, including domest ic andinternational political developments, government tradeand fiscal policies, patterns of trade and war or othermilitary conflict which may affect industries or marketsor the economy generally.

Foreign Stocks. Because the New World LeadersPortfolio invests significantly in foreign stocks, the NewWorld Leaders Portfolio involves additional risks thatdiffer from an investment in domestic stocks. Theserisks include the risk of losses due to future politicaland economic developments, international tradeconditions, foreign withholding taxes and restrictionson foreign investments or exchange of securities,foreign currency fluctuations or restriction on exchangeor repatriation of currencies.

The political, economic and social structures of someforeign countries may be less stable and more volatilethan those in the U.S. Investments in these countriesmay be subject to the risks of internal and externalconflicts, currency devaluations, foreign ownershiplimitations and tax increases. It is possible that agovernment may take over the assets or operations of acompany or impose restrictions on the exchange orexport of currency or other assets. Some countries alsomay have different legal systems that may make itdifficult for the Portfolio to vote proxies, exerciseinvestor rights, and pursue legal remedies with respectto its foreign investments. Diplomatic and politicaldevelopments, including rapid and adverse politicalchanges, social instability, regional conflicts, terrorismand war, could affect the economies, industries, andsecurities and currency markets, and the value of thePortfolio’s investments, in non-U.S. countries. No onecan predict the impact that these factors could have onthe Portfolio’s securities.

In addition, for foreign securities of European issuers,the departure of any European Union (“EU”) memberfrom use of the Euro could lead to serious disruptionsto foreign exchanges, operations and settlements,which may have an adverse effect on European issuers.More recently, there is particular uncertainty regardingthe state of the EU following the United Kingdom's("U.K.") official exit from the EU on January 31, 2020("Brexit"). While a trade deal was negotiated andprovisionally went into effect on January 1, 2021, Brexitmarks the first time that a significant member of the EUwill have left. The effect that Brexit may have on theglobal financial markets is uncertain. No one can predict

A-3

A-4

the impact that these factors could have on thesecurities held by your Portfolio.

Certain stocks may be held in the form of AmericanDepositary Receipts (“ADRs”), Global DepositaryReceipts (“GDRs”), or other similar receipts. ADRs andGDRs represent receipts for foreign common stockdeposited with a custodian (which may include theTrustee). The ADRs in the Portfolio, if any, trade in theU.S. in U.S. dol lars and are registered with theSecurities and Exchange Commission (“SEC”). GDRsare receipts, issued by foreign banks or trustcompanies, or foreign branches of U.S. banks, thatrepresent an interest in shares of either a foreign or U.S.corporation. These instruments may not necessarily bedenominated in the same currency as the securities intowhich they may be converted. ADRs and GDRsgenerally involve the same types of risks as foreigncommon stock held directly. Some ADRs and GDRsmay experience less liquidity than the underlyingcommon stocks traded in their home market. ThePortfolio may invest in sponsored or unsponsoredADRs. Unlike a sponsored ADR where the depositaryhas an exclusive relationship with the foreign issuer, anunsponsored ADR may be created by a depositaryinstitution independently and without the cooperation ofthe foreign issuer. Consequently, information concerningthe foreign issuer may be less current or reliable for anunsponsored ADR and the price of an unsponsoredADR may be more volatile than if it was a sponsoredADR. Depositaries of unsponsored ADRs are notrequired to distribute shareholder communicationsreceived from the foreign issuer or to pass throughvoting rights to its holders. The holders of unsponsoredADRs generally bear all the costs associated withestablishing the unsponsored ADR, whereas the foreignissuers typically bear certain costs in a sponsored ADR.The value of the depositary receipt in terms of U.S.dollars, and therefore the value of your Units, willdecline if the U.S. dollar decreases in value relative tothe value of the currency in which the underlying foreigncommon stock is denominated. Most foreign currencieshave fluctuated widely in value against the U.S. dollarfor various economic and political reasons.

Foreign companies may not be subject to the samedisclosure, accounting, auditing and financial reportingstandards and practices as U.S. companies. Thus,there may be less information publicly available aboutforeign companies than about most U.S. companies.

Certain foreign securities may be less liquid (harder tosell) and more volatile than many U.S. securities. Thismeans the Portfolio may at times be unable to sell foreignsecurities in a timely manner or at favorable prices.

European Issuers. The New World Leaders Portfolioinvests significantly in securities issued by Europeancompanies. Investments in a single region, even thoughrepresenting a number of different countries within theregion, may be affected by common economic forcesand other factors. A significant number of countries inEurope are member states in the EU and no longercontrol their own monetary policies by directingindependent interest rates for their currencies. In thesemember states, the authority to direct monetary policiesincluding money supply and official interest rates for theEuro is exercised by the European Central Bank. TheEuropean sovereign debt crisis and the related austeritymeasures in certain countries have had, and continue tohave, a significant impact on the economies of certainEuropean countries and their future economic outlooks.Further, political or economic disruptions in Europeancountries, even in countries in which your Portfolio is notinvested, may adversely affect security values and thusthe Portfolio's holdings. The risks associated withinvesting in European securities may be heightenedbecause of risks due to the inexperience of financialintermediaries, the lack of modern technology, the lack ofa sufficient capital base to expand business operationsand the possibility of permanent or temporary terminationof trading, and any impact that Brexit, as previouslydescribed, may have on the region as a whole.

Industry Risks. Each Portfol io may investsignificantly in certain industries. Any negative impacton the related industry will have a greater impact on thevalue of Units than on a portfolio diversified over severalindustries. You should understand the risks of theseindustries before you invest.

A-5

The relative weighting or composition of yourPortfolio may change during the life of your Portfolio.Following the Initial Date of Deposit, the Sponsorintends to issue additional Units by depositing in yourPortfolio additional securities in a manner consistentwith the provisions described in the above sectionentitled “The Portfolios”. As described in that section, itmay not be possible to retain or continue to purchaseone or more Securities in your Portfolio. In addition, dueto certain limited circumstances described under“Portfolio Administration”, the composition of theSecurities in your Portfolio may change. Accordingly,the fluctuations in the relative weighting or compositionof your Portfolio may result in concentrations (25% ormore of a Portfolio’s assets) in securities of a particulartype, industry and/or geographic region. As of the InitialDate of Deposit, each Portfolio was significantlyinvested in the following to the extent described below.

Aerospace and Defense Issuers. The U.S. DefensePortfolio invests exclusively in companies involved inthe aerospace and defense industries, which includescompanies operating in the industrials industry. Thesecompanies are subject to numerous risks, includingfierce competition, consolidation, adverse political,economic and governmental developments (both in theU.S. and abroad), compliance with varying regulationacross international markets, substantial research anddevelopment costs, cuts in government funding,product and technology obsolescence, l imitednumbers of potential customers and decreaseddemand for new equipment.

Aerospace and defense companies generally derivea significant portion of their revenue from contracts withthe U.S. Government as wel l as with foreigngovernments. In many cases, an issuer in the Portfoliomay have contracts with only a few entities, including,or even solely with, the U.S. Government. As a result,issuers in the Portfolio engaged in contracts with theU.S. Government will be subject to many of the risksthat general ly affect government contractors.Companies in these industries can be significantlyaffected by applicable government regulation andspending policies, and by fluctuating governmentdemand for their products and services. Levels of

government spending for the products and servicesprovided by such government contractors are ofteninfluenced by political support. A significant decline orredirection of U.S. military expenditures in the futurecould adversely affect the sales and earnings of suchcompanies.

Issuers deriving revenue from contracts with theU.S. Government, and defense companies in particular,face a number of specific risks that may adverselyaffect a company's financial condition and outlook. TheU.S. Government may terminate a contract with anissuer as a result of an issuer's default, resulting inpossible issuer liability to the U.S. Government. TheU.S. Government may terminate a contract for its ownconvenience, which may lead to difficulty for the issuerin recovering costs incurred prior to termination. Suchcontracts may also be modified or terminated due tochanges in congressional funding levels. Governmentcontractors are also subject to stringent routine auditsand reviews, which may lead to significant priceadjustments for products and services. The highlycompetitive bidding environment in which governmentcontractors operate may also reduce the profitability ofcertain government contracts.

Companies involved in the commercial aerospaceindustry are subject to risks including aircraft ordercancellations, changes in aircraft-leasing contracts,excess capacity, cutbacks in profitable business travel,fuel price hikes, labor union settlements, adversechanges in international politics and relations, intenseglobal competition, government regulation and cyclicalmarket patterns. Furthermore, competition in theairline industry continues to increase as a result ofairline deregulation.

Consumer Discretionary and Consumer StaplesIssuers. The American Innovation Leaders Portfolio andthe New World Leaders Portfolio invest significantly incompanies that manufacture or sell various consumerproducts. General risks of these companies include theoverall state of the economy, intense competition andconsumer spending trends. A decline in the economywhich results in a reduction of consumers’ disposableincome can negatively impact spending habits. Globalfactors including political developments, imposition of

A-6

import controls, fluctuations in oil prices, and changesin exchange rates may adversely affect issuers ofconsumer products and services.

Competitiveness in the retail industry may requirelarge capital outlays for the installation of automatedcheckout equipment to control inventory, track the saleof items and gauge the success of sales campaigns.Retailers who sell their products over the Internet havethe potential to access more consumers, but mayrequire sophisticated technology to remain competitive.Changes in demographics and consumer tastes canalso affect the demand for, and the success of,consumer products and services in the marketplace.Consumer goods and services companies may besubject to government regulation affecting theirproducts and operations which may negatively impactperformance. Tobacco companies may be adverselyaffected by new laws, regulations and litigation.

Health Care Issuers. The American InnovationLeaders Port fo l io and the New Wor ld LeadersPortfolio invest significantly in health care companies.These issuers inc lude companies involved inadvanced medical devices and instruments, drugsand biotechnology, managed care, hospi ta lmanagement/health services and medical supplies.These companies face substant ia l governmentregulation and approval procedures. General risks ofhealth care companies include extensive competition,product liability litigation and evolving governmentregulation.

On March 30, 2010, the Health Care and EducationReconciliation Act of 2010 (incorporating the PatientProtection and Affordable Care Act, collectively the“Act”) was enacted into law. The Act continues to havea significant impact on the health care industry throughthe implementation of a number of reforms in a complexand ongoing process, with varying effective dates.Significant provisions of the Act include the introductionof required health care coverage for most Americans,significant expansion in the number of Americanseligible for Medicaid, modification of taxes and taxcredits in the health care industry, and subsidizedinsurance for low to middle income families. The Actalso provides for more thorough regulation of private

health insurance providers, including a prohibition onthe denial of coverage due to pre-existing conditions.

In late 2017, along with the passage of sweeping taxreform, legislation was passed which eliminated theindividual mandate (a penalty for failure to obtain aminimum level of health insurance coverage) beginningin 2019. It is estimated that the repeal of the individualmandate will cause a significant amount of people to beuninsured which may have an adverse effect oninsurance premiums and federal subsidies. TheSponsor is unable to predict the full impact of the Act,or of its potential repeal or modification, on theSecurities in your Portfolio.

As illustrated by the Act, Congress may from time totime propose legislative action that will impact thehealth care industry. The proposals may span a widerange of topics, including cost and price controls (whichmay include a freeze on the prices of prescriptiondrugs), incentives for competition in the provision ofhealth care services, promotion of pre-paid health careplans and additional tax incentives and penalties aimedat the health care industry. The government could alsoreduce funding for health care related research.

Drug and medical products companies also face therisk of increasing competition from new products orservices, generic drug sales, product obsolescence,increased government regulation, obtaining anddefending patents, the expiration of patent protectionfor drug or medical supply products and the risk that aproduct will never come to market. The research anddevelopment costs of bringing a new drug or medicalproduct to market are substantial. This process involveslengthy government review with no guarantee ofapproval. These companies may have losses and maynot offer proposed products for several years, if at all.The failure to gain approval for a new drug or productcan have a substantial negative effect on a companyand its stock.

Health care equipment and supplier companies arealso affected by rising costs of medical products,devices and services and the increased emphasis onthe delivery of health care through outpatient services.Competition among health care equipment and supplier

A-7

companies is high and can be significantly affected byextensive government regulation or restrictions ongovernment reimbursement for medical expenses. Thegoods and services of health care issuers are alsosubject to risks of malpractice claims, product liabilityclaims or other litigation. Health care facility operatorsface risks related to demand for services, the ability ofthe facility to provide required services, an increasedemphasis on outpatient services, confidence in thefacility, management capabilities, competitive forcesthat may result in price discounting, efforts by insurersand government agencies to limit rates, expenses, thecost and possible unavai labi l i ty of malpracticeinsurance, and termination or restriction of governmentfinancial assistance (such as Medicare, Medicaid orsimilar programs).

Industrials Issuers. The U.S. Defense Portfolio investssignificantly in industrials companies. General risks ofindustrials companies include the general state of theeconomy, intense competition, imposition of importcontrols, volatil ity in commodity prices, currencyexchange rate fluctuation, consolidation, labor relations,domestic and international politics, excess capacity andconsumer spending trends. Companies in theindustrials industry may be adversely affected by liabilityfor environmental damage and product liability claims.Capital goods companies may also be significantlyaffected by overall capital spending and leverage levels,economic cycles, technical obsolescence, delays inmodernization, limitations on supply of key materials,depletion of resources, government regulations,government contracts and e-commerce initiatives.

Industrials companies may also be affected by factorsmore specific to their individual industries. Industrialmachinery manufacturers may be subject to declines incommercial and consumer demand and the need formodernization. Aerospace and defense companies maybe influenced by decreased demand for new equipment,aircraft order cancellations, disputes over or ability toobtain or retain government contracts, changes ingovernment budget priorities, changes in aircraft-leasingcontracts and cutbacks in profitable business travel. Thenumber of housing starts, levels of public and non-residential construction including weakening demand for

new office and retail space, and overall constructionspending may adversely affect construction materialsand equipment manufacturers. Stocks of transportationcompanies are cyclical and can be significantly affectedby economic changes, fuel prices and insurance costs.Transportation companies in certain countries may alsobe subject to significant government regulation andoversight, which may negatively impact their businesses.

Technology and Information Technology Issuers.The Global Technology Leaders Portfolio investsprimari ly, and the American Innovation LeadersPortfolio invests significantly, in companies in thetechnology industry, which includes informationtechnology companies. The technology industryincludes companies that are involved in computer andbusiness services, enterprise software/technicalsoftware, Internet and computer software, Internet-related services, networking and telecommunicationsequipment, telecommunications services, electronicsproducts, server hardware, computer hardware andperipherals, semiconductor capital equipment andsemiconductors. These companies face risks relatedto rapidly changing technology, rapid productobsolescence, cyclical market patterns, evolvingindustry standards and frequent new productintroductions.

Companies in this industry face risks from rapidchanges in technology, competition, dependence oncertain suppliers and supplies, rapid obsolescence ofproducts or services, patent termination, frequent newproducts and government regulat ion. Thesecompanies can also be adversely affected byinterruption or reduction in supply of components orloss of key customers and failure to comply withcertain industry standards.

An unexpected change in technology can have asignificant negative impact on a company. The failure ofa company to introduce new products or technologiesor keep pace with rapidly changing technology canhave a negative impact on the company’s results.Certain technology companies may also be smallerand/or less experienced companies with limited productlines, markets or resources. Stocks of some Internetcompanies have high price-to-earnings ratios with little

A-8

or no earnings histories. Technology stocks tend toexperience substantial price volatility and speculativetrading. Announcements about new products,technologies, operating results or marketing alliancescan cause stock prices to fluctuate dramatically. Attimes, however, extreme price and volume fluctuationsare unrelated to the operating performance of acompany. This can impact your ability to redeem yourUnits at a price equal to or greater than what you paid.

Liquidity Risk. Liquidity risk is the risk that the valueof a security will fall if trading in the security is limited orabsent. The market for certain investments may becomeless liquid or illiquid due to adverse changes in theconditions of a particular issuer or due to adversemarket or economic conditions. In the absence of aliquid trading market for a particular security, the price atwhich such security may be sold to meet redemptions,as well as the value of the Units of your Portfolio, may beadversely affected. No one can guarantee that a liquidtrading market will exist for any security.

Legislation/Litigation. From time to time, variouslegislative initiatives are proposed in the United Statesand abroad which may have a negative impact oncertain of the companies represented in your Portfolio,or on the tax treatment of your Portfolio or of yourinvestment in a Portfolio. In addition, litigation regardingany of the issuers of the Securities or of the industriesrepresented by these issuers may negatively impact theshare prices of these Securities. No one can predictwhat impact any pending or threatened litigation willhave on the share prices of the Securities.

No FDIC Guarantee. An investment in yourPortfolio is not a deposit of any bank and is not insuredor guaranteed by the Federal Deposit InsuranceCorporation or any other government agency.

PUBLIC OFFERING

General. Units are offered at the Public OfferingPrice which consists of the net asset value per Unit plusorganization costs plus the sales charge. The net assetvalue per Unit is the value of the securities, cash andother assets in your Portfolio reduced by the liabilities ofthe Portfolio divided by the total Units outstanding. The

maximum sales charge equals 1.85% of the PublicOffering Price per Unit (1.885% of the aggregateoffering price of the Securities) at the time of purchase.

The initial sales charge is the difference between thetotal sales charge amount (maximum of 1.85% of thePublic Offering Price per Unit) and the sum of theremaining fixed dollar deferred sales charge and thefixed dollar creation and development fee (initially$0.185 per Unit). Depending on the Public OfferingPrice per Unit, you pay the initial sales charge at thetime you buy Units. The deferred sales charge is fixedat $0.135 per Unit. Your Portfolio pays the deferredsales charge in installments as described in the “FeeTable.” If any deferred sales charge payment date isnot a business day, we will charge the payment on thenext business day. If you purchase Units after the initialdeferred sales charge payment, you will only pay thatportion of the payments not yet collected. If youredeem or sell your Units prior to collection of the totaldeferred sales charge, you will pay any remainingdeferred sales charge upon redemption or sale of yourUnits. The initial and deferred sales charges arereferred to as the “transactional sales charge.” Thetransactional sales charge does not include thecreation and development fee which compensates theSponsor for creating and developing your Portfolio andis described under “Expenses.” The creation anddevelopment fee is fixed at $0.05 per Unit. YourPortfolio pays the creation and development fee as ofthe close of the initial offering period as described inthe “Fee Table.” If you redeem or sell your Units prior tocollection of the creation and development fee, you willnot pay the creation and development fee uponredemption or sale of your Units. After the initial offeringperiod the maximum sales charge will be reduced by0.50%, reflecting the previous collection of the creationand development fee. Because the deferred salescharge and creation and development fee are fixeddollar amounts per Unit, the actual charges will exceedthe percentages shown in the “Fee Table” if the PublicOffering Price per Unit falls below $10 and will be lessthan the percentages shown in the “Fee Table” if thePublic Offering Price per Unit exceeds $10. In no event

A-9

will the maximum total sales charge exceed 1.85% ofthe Public Offering Price per Unit.

The “Fee Table” shows the sales charge calculation ata $10 Public Offering Price per Unit. At a $10 PublicOffering Price, there is no initial sales charge during theinitial offering period. If the Public Offering Price exceeds$10 per Unit, you will pay an initial sales charge equal tothe difference between the total sales charge and thesum of the remaining deferred sales charge and thecreation and development fee. For example, if the PublicOffering Price per Unit rose to $14, the maximum salescharge would be $0.259 (1.85% of the Public OfferingPrice per Unit), consisting of an initial sales charge of$0.074, a deferred sales charge of $0.135 and thecreation and development fee of $0.050.

Since the deferred sales charge and creation anddevelopment fee are fixed dollar amounts per Unit, yourPortfol io must charge these amounts per Unitregardless of any decrease in net asset value. However,if the Public Offering Price per Unit falls to the extentthat the maximum sales charge percentage results in adollar amount that is less than the combined fixed dollaramounts of the deferred sales charge and creation anddevelopment fee, your initial sales charge will be a creditequal to the amount by which these fixed dollar chargesexceed your sales charge at the time you buy Units. Insuch a situation, the value of securities per Unit wouldexceed the Public Offering Price per Unit by the amountof the initial sales charge credit and the value of thosesecurities will fluctuate, which could result in a benefit ordetriment to Unitholders that purchase Units at thatprice. The initial sales charge credit is paid by theSponsor and is not paid by the Portfolio. If the PublicOffering Price per Unit fell to $6, the maximum salescharge would be $0.111 (1.85% of the Public OfferingPrice per Unit), which consists of an initial sales charge(credit) of -$0.074, a deferred sales charge of $0.135and a creation and development fee of $0.050.

The actual sales charge that may be paid by aninvestor may differ slightly from the sales chargesshown herein due to rounding that occurs in thecalculation of the Public Offering Price and in thenumber of Units purchased.

The minimum purchase is 100 Units (25 Units forretirement accounts) but may vary by selling firm.Certain broker-dealers or selling firms may charge anorder handling fee for processing Unit purchases.

Reducing Your Sales Charge. The Sponsoroffers ways for you to reduce the sales charge that youpay. It is your financial professional’s responsibility toalert the Sponsor of any discount when you purchaseUnits. Before you purchase Units you must also informyour financial professional of your qualification for anydiscount to be eligible for a reduced sales charge. Sincethe deferred sales charges and creation anddevelopment fee are fixed dollar amounts per Unit, yourPortfol io must charge these amounts per Unitregardless of any discounts. However, if you are eligibleto receive a discount such that your total sales chargeis less than the fixed dollar amounts of the deferredsales charges and creation and development fee, youwill receive a credit equal to the difference between yourtotal sales charge and these fixed dollar charges at thetime you buy Units.

Fee Accounts. Investors may purchase Units throughregistered investment advisers, certified financialplanners and registered broker-dealers who in eachcase either charge periodic fees for brokerage services,f inancial planning, investment advisory or assetmanagement services, or provide such services inconnection with the establishment of an investmentaccount for which a comprehensive “fee based” charge(“Fee Based”) is imposed (“Fee Accounts”). If Units of aPortfolio are purchased for a Fee Account and thePortfolio is subject to a Fee Based charge (i.e., thePortfolio is “Fee Based Eligible”), then the purchase willnot be subject to the transactional sales charge but willbe subject to the creation and development fee of$0.05 per Unit that is retained by the Sponsor. Pleaserefer to the section called “Fee Accounts” for additionalinformation on these purchases. The Sponsor reservesthe right to limit or deny purchases of Units described inthis paragraph by investors or selling firms whosefrequent trading activity is determined to be detrimentalto a Portfolio. Fee Based Eligible Units are not eligiblefor any sales charge discounts in addition to that which

A-10

is described in this paragraph and under the “FeeAccounts” section found below.

Employees. Employees, officers and directors(including their spouses (or the equivalent if recognizedunder local law) and children or step-children under 21living in the same household, parents or step-parentsand trustees, custodians or fiduciaries for the benefit ofsuch persons) of Invesco Capital Markets, Inc. and itsaffiliates, and dealers and their affiliates may purchaseUnits at the Public Offering Price less the applicabledealer concession. All employee discounts are subjectto the pol icies of the related sel l ing f irm. Onlyemployees, officers and directors of companies thatallow their employees to participate in this employeediscount program are eligible for the discounts.

Distribution Reinvestments. We do not charge anysales charge when you reinvest distributions from yourPortfolio into additional Units of your Portfolio. Since thedeferred sales charges and creation and developmentfee are fixed dollar amounts per unit, your Portfolio mustcharge these amounts per unit regardless of thisdiscount. If you elect to reinvest distributions, theSponsor will credit you with additional Units with adollar value sufficient to cover the amount of anyremaining deferred sales charge and creation anddevelopment fee that will be collected on such Units atthe time of reinvestment. The dollar value of these Unitswill fluctuate over time.

Unit Price. The Public Offering Price of Units willvary from the amounts stated under “EssentialInformation” in accordance with fluctuations in the pricesof the underlying Securities in the Portfolios. The initialprice of the Securities upon deposit by the Sponsor wasdetermined by the Trustee. The Trustee will generallydetermine the value of the Securities as of the EvaluationTime on each business day and will adjust the PublicOffering Price of Units accordingly. The Evaluation Timeis the close of the New York Stock Exchange on eachbusiness day. The term “business day”, as used hereinand under “Rights of Unitholders--Redemption of Units”,means any day on which the New York Stock Exchangeis open for regular trading. The Public Offering Price perUnit will be effective for all orders received prior to theEvaluation Time on each business day. Orders received

by the Sponsor prior to the Evaluation Time and ordersreceived by authorized financial professionals prior to theEvaluation Time that are properly transmitted to theSponsor by the time designated by the Sponsor, arepriced based on the date of receipt. Orders received bythe Sponsor after the Evaluation Time, and ordersreceived by authorized financial professionals after theEvaluation Time or orders received by such persons thatare not transmitted to the Sponsor until after the timedesignated by the Sponsor, are priced based on thedate of the next determined Public Offering Price perUnit provided they are received timely by the Sponsor onsuch date. It is the responsibility of authorized financialprofessionals to transmit orders received by them to theSponsor so they will be received in a timely manner.

The value of portfolio securities is based on thesecurities’ market price when available. When a marketprice is not readily available, including circumstancesunder which the Trustee determines that a security’smarket price is not accurate, a portfolio security isvalued at its fair value, as determined under proceduresestablished by the Trustee or an independent pricingservice used by the Trustee. In these cases, a Portfolio’snet asset value will reflect certain portfolio securities’ fairvalue rather than their market price. With respect tosecurities that are primarily listed on foreign exchanges,the value of the portfolio securities may change on dayswhen you will not be able to purchase or sell Units. Thevalue of any foreign securit ies is based on theapplicable currency exchange rate as of the EvaluationTime. The Sponsor will provide price dissemination andoversight services to the Portfolios.

During the initial offering period, part of the PublicOffering Price represents an amount that will pay thecosts incurred in establishing your Portfolio. Thesecosts include the costs of preparing documents relatingto the Portfolio (such as the registration statement,prospectus, trust agreement and legal documents),federal and state registration fees, the initial fees andexpenses of the Trustee and the initial audit. YourPortfolio will sell securities to reimburse us for thesecosts at the end of the initial offering period or after sixmonths, if earlier. The value of your Units will declinewhen the Portfolio pays these costs.

A-11

See“Rights of Unitholders--Reinvestment Option.”

RIGHTS OF UNITHOLDERS

Distributions. With respect to the Portfolios offeredin this prospectus (with the exception of the U.S.Defense Portfolio), dividends and interest, net ofexpenses, and any net proceeds from the sale ofSecurities received by a Portfolio will generally bedistributed to Unitholders on each Distribution Date toUnitholders of record on the preceding Record Date.With respect to the U.S. Defense Portfolio, the Trusteewill generally distribute the cash held in the Income andCapital Accounts of your portfolio, net of expenses, oneach Distribution Date to Unitholders of record on thepreceding Record Date, provided that the total cashheld for distribution equals at lease 0.1% of yourPortfolio’s net asset value. These dates appear under“Essential Information”. Distributions made by any real

estate investment trusts in the New World LeadersPortfolio include ordinary income, but may also includesources other than ordinary income such as returns ofcapital, loan proceeds, short-term capital gains andlong-term capital gains (see “Taxation--Distributions”). Inaddition, the Portfolios (except the U.S. DefensePortfolio, which is structured as a grantor trust) willgenerally make required distributions at the end of eachyear because each is structured as a “regulatedinvestment company” (“RIC”) for federal tax purposes.Unitholders will also receive a final distribution of incomewhen their Portfolio terminates. A person becomes aUnitholder of record on the date of settlement (generallytwo business days after Units are ordered or anyshorter period as may be required by the applicablerules under the 1934 Act). Unitholders may elect toreceive distributions in cash or to have distributionsreinvested into addit ional Units. See “Rights ofUnitholders--Reinvestment Option”.

Dividends and interest received by a Portfolio arecredited to the Income Account of the Portfolio. Otherreceipts (e.g., capital gains, proceeds from the sale ofSecurities, etc.) are credited to the Capital Account.Proceeds received on the sale of any Securities, to theextent not used to meet redemptions of Units or paydeferred sales charges, fees or expenses, will bedistributed to Unitholders. Proceeds received from thedisposition of any Securities after a Record Date andprior to the following Distribution Date will be held in theCapital Account and not distributed until the nextDistribution Date. Any distribution to Unitholdersconsists of each Unitholder’s pro rata share of theavailable cash in the Income and Capital Accounts as ofthe related Record Date.

Historical and Estimated Distributions. Thehistorical annual income per Unit, and estimated initialdistribution per Unit (if any), may be shown under“Essential Information.” These figures are based ondistribution data from the 12 month period precedingthe Initial Date of Deposit. Generally, these figures arebased upon several recently declared dividends ordistributions within the preceding 12 month period, aswell as interim and final dividends or distributions offoreign issuers (accounting for any foreign withholding

A-14

taxes or additional declared distributions). With respectto domestic common stock issuers, these figures aretypically based upon the most recent ordinary quarterlydividend, which is annualized. However, commonstocks do not assure dividend payments and thereforethe amount of future dividend income to your Portfoliois uncertain. The actual net annual distributions maydecrease over time because a portion of the Securitiesincluded in your Portfolio will be sold to pay for theorganization costs, deferred sales charge and creationand development fee. Securities may also be sold topay regular fees and expenses during your Portfolio’slife. Dividend and income conventions for certaincompanies and/or certain countries differ from thosetypically used in the United States and in certaininstances, dividends/income paid or declared overseveral years or other periods may be used to calculatehistorical annual distributions. The actual net annualincome distributions you receive will vary from thehistorical annual distribution amount due to changes individends and distribution amounts paid by the issuers;currency fluctuations; the sale of Securities to pay anydeferred sales charge; Portfolio fees and expenses; andwith changes in your Portfolio such as the acquisition,call, maturity or sale of Securities. In addition, due to thenegative economic impact across many industriescaused by the recent COVID-19 outbreak, certainissuers of the securities included in a Portfolio may electto reduce the amount of, or cancel entirely, dividendsand/or distributions paid in the future. As a result, theHistorical 12 Month Distr ibutions per Unit, andEstimated Initial Distribution per Unit (if any), shownunder “ Essential Information” will likely be higher, and insome cases signif icantly higher, than the actualdistributions achieved by a Portfolio. Due to these andvarious other factors, actual income received by yourPortfolio will most likely differ from the most recentdividends or scheduled income payments.

Reinvestment Option. Unitholders may havedistributions automatically reinvested in additional Unitswithout a sales charge (to the extent Units may belawfully offered for sale in the state in which theUnitholder resides). The CUSIP numbers for either“Cash” distributions or “Reinvest” for the reinvestment

of distr ibut ions are set forth under “Essent ia lInformation”. Brokers and dealers can use the DividendReinvestment Service through Depository TrustCompany (“DTC”) or purchase a Reinvest (or FeeBased Reinvest in the case of Fee Based Eligible Unitsheld in Fee Accounts) CUSIP, if available. To participatein this reinvestment option, a Unitholder must file withthe Trustee a written notice of election, together withany other documentation that the Trustee may thenrequire, at least five days prior to the related RecordDate. A Unitholder’s election will apply to all Unitsowned by the Unitholder and will remain in effect untilchanged by the Unitholder. The reinvestment option isnot offered during the 30 calendar days prior totermination. If Units are unavailable for reinvestment orthis reinvestment option is no longer avai lable,distributions will be paid in cash. Distributions will betaxable to Unitholders if paid in cash or automaticallyreinvested in additional Units. See “Taxation”.

A participant may elect to terminate his or herreinvestment plan and receive future distributions incash by notifying the Trustee in writing no later than fivedays before a Distribution Date. The Sponsor shallhave the r ight to suspend or terminate thereinvestment plan at any time. The reinvestment plan issubject to availability or limitation by each broker-dealeror sel l ing f i rm. Broker-dealers may suspend orterminate the offering of a reinvestment plan at anytime. Please contact your financial professional foradditional information.

Redemption of Units. All or a portion of your Unitsmay be tendered to The Bank of New York Mellon, theTrustee, for redemption at Unit Investment TrustDivision, 111 Sanders Creek Parkway, East Syracuse,New York 13057, on any day the New York StockExchange is open. No redemption fee will be chargedby the Sponsor or the Trustee, but you are responsiblefor applicable governmental charges, if any. Unitsredeemed by the Trustee will be canceled. You mayredeem all or a portion of your Units by sending arequest for redemption to your bank or broker-dealerthrough which you hold your Units. No later than twobusiness days (or any shorter period as may berequired by the applicable rules under the 1934 Act)

A-15

following satisfactory tender, the Unitholder will beentitled to receive in cash an amount for each Unitequal to the Redemption Price per Unit next computedon the date of tender. The “date of tender” is deemed tobe the date on which Units are received by the Trustee,except that with respect to Units received by theTrustee after the Evaluation Time or on a day which isnot a business day, the date of tender is deemed to bethe next business day. Redemption requests receivedby the Trustee after the Evaluation T ime, andredemption requests received by authorized financialprofessionals after the Evaluation Time or redemptionrequests received by such persons that are nottransmitted to the Trustee until after the time designatedby the Trustee, are priced based on the date of the nextdetermined redemption price provided they are receivedtimely by the Trustee on such date. It is theresponsibility of authorized financial professionals totransmit redemption requests received by them to theTrustee so they will be received in a timely manner.Certain broker-dealers or selling firms may charge anorder handling fee for processing redemption requests.Units redeemed directly through the Trustee are notsubject to such fees.

Unitholders tendering 1,000 or more Units (or suchhigher amount as may be required by yourbroker-dealer or selling agent) for redemption mayrequest an in kind distribution of Securities equal to theRedemption Price per Unit on the date of tender.Unitholders may not request an in kind distributionduring the initial offering period or within 30 calendardays of a Portfolio’s termination. The Portfolios generallywill not offer in kind distributions of portfolio securitiesthat are held in foreign markets. An in kind distributionwill be made by the Trustee through the distribution ofeach of the Securities in book-entry form to the accountof the Unitholder’s broker-dealer at DTC. Amountsrepresenting fractional shares will be distributed in cash.The Trustee may adjust the number of shares of anySecurity included in a Unitholder’s in kind distribution tofacilitate the distribution of whole shares. The in kinddistribution option may be modified or discontinued atany time without notice. Notwithstanding the foregoing,if the Unitholder requesting an in kind distribution is the

Sponsor or an affiliated person of the Portfolio, theTrustee may make an in kind distribution to suchUnitholder provided that no one with a pecuniaryincentive to influence the in kind distribution mayinfluence selection of the distributed securities, thedistribution must consist of a pro rata distribution of allportfolio securities (with limited exceptions) and the inkind distribution may not favor such affiliated person tothe detriment of any other Unitholder. Unitholders willincur transaction costs in liquidating securities receivedin an in-kind distribution, and any such securitiesreceived will be subject to market risk until sold. In theevent that any securities received in-kind are illiquid,Unitholders will bear the risk of not being able to sellsuch securities in the near term, or at all.

The Trustee may sell Securities to satisfy Unitredemptions. To the extent that Securit ies areredeemed in kind or sold, the size of a Portfolio will be,and the diversity of a Portfolio may be, reduced. Salesmay be required at a time when Securities would nototherwise be sold and may result in lower prices thanmight otherwise be realized. The price received uponredemption may be more or less than the amount paidby the Unitholder depending on the value of theSecurities at the time of redemption. Special federalincome tax consequences will result if a Unitholderrequests an in kind distribution. See “Taxation”.

The Redemption Price per Unit and the secondarymarket repurchase price per Unit are equal to the prorata share of each Unit in each Portfolio determined onthe basis of (i) the cash on hand in the Portfolio, (ii) thevalue of the Securities in the Portfolio and (iii) dividendsor other income distr ibutions receivable on theSecurities in the Portfolio trading ex-dividend as of thedate of computation, less (a) amounts representingtaxes or other governmental charges payable out of thePortfolio, (b) the accrued expenses of the Portfolio(including costs associated with liquidating securitiesafter the end of the initial offering period) and (c) anyunpaid deferred sales charge payments. During theinitial offering period, the redemption price and thesecondary market repurchase price will not be reducedby estimated organization costs or the creation anddevelopment fee. For these purposes, the Trustee will

A-16

determine the value of the Securities as describedunder “Public Offering--Unit Price”.

The right of redemption may be suspended andpayment postponed for any period during which theNew York Stock Exchange is closed, other than forcustomary weekend and holiday closings, or anyperiod during which the SEC determines that tradingon that Exchange is restricted or an emergency exists,as a result of which disposal or evaluation of theSecurities is not reasonably practicable, or for otherperiods as the SEC may permit.

Exchange Option. When you redeem Units of yourPortfol io or when your Portfol io terminates (see“Rollover” below), you may be able to exchange yourUnits for units of other Invesco unit trusts. You shouldcontact your financial professional for more informationabout trusts currently available for exchanges. Beforeyou exchange Units, you should read the prospectus ofthe new trust carefully and understand the risks andfees. You should then discuss this option with yourfinancial professional to determine whether yourinvestment goals have changed, whether current trustssuit you and to discuss tax consequences. A rollover orexchange is a taxable event to you. We maydiscontinue this option at any time.

Rollover. We may offer a subsequent series of eachPortfolio for a Rollover when the Portfolios terminate.

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

If you elect to participate in a cash Rollover, yourUnits will be redeemed on the Mandatory TerminationDate. As the redemption proceeds become available,the proceeds (including dividends) will be invested in anew trust series at the public offering price for the newtrust. The Trustee will attempt to sell Securities to satisfythe redemption as quickly as practicable on theMandatory Termination Date. We do not anticipate thatthe sale period will be longer than one day, however,certain factors could affect the ability to sell theSecurities and could impact the length of the saleperiod. The liquidity of any Security depends on the

daily trading volume of the Security and the amountavailable for redemption and reinvestment on any day.

We may make subsequent trust series available forsale at various times during the year. Of course, wecannot guarantee that a subsequent trust or sufficientunits will be available or that any subsequent trusts willoffer the same investment strategies or objectives as thecurrent Portfolios. We cannot guarantee that a Rolloverwill avoid any negative market price consequencesresulting from trading large volumes of securities. Marketprice trends may make it advantageous to sell or buysecurities more quickly or more slowly than permitted bythe Portfolio procedures. We may, in our sole discretion,modify a Rollover or stop creating units of a trust at anytime regardless of whether all proceeds of Unitholdershave been reinvested in a Rollover. If we decide not tooffer a subsequent series, Unitholders will be notifiedprior to the Mandatory Termination Date. Cash whichhas not been reinvested in a Rollover will be distributedto Unitholders shortly after the Mandatory TerminationDate. Rollover participants may receive taxabledividends or realize taxable capital gains which arereinvested in connection with a Rollover but may not beentitled to a deduction for capital losses due to the“wash sale” tax rules. Due to the reinvestment in asubsequent trust, no cash will be distributed to pay anytaxes. See “Taxation”.

Units. Ownership of Units is evidenced inbook-entry form only and will not be evidenced bycertificates. Units purchased or held through your bankor broker-dealer will be recorded in book-entry formand credited to the account of your bank orbroker-dealer at DTC. Units are transferable bycontacting your bank or broker-dealer through whichyou hold your Units. Transfer, and the requirementstherefore, wi l l be governed by the appl icableprocedures of DTC and your agreement with the DTCparticipant in whose name your Units are registered onthe transfer records of DTC.

Reports Provided. Unitholders will receive astatement of dividends and other amounts received bya Portfolio for each distribution. Within a reasonabletime after the end of each year, each person who was aUnitholder during that year will receive a statement

A-17

describing dividends and capital received, actualPortfolio distributions, Portfolio expenses, a list of theSecurities and other Portfolio information. Unitholdersmay obtain evaluations of the Securities upon requestto the Trustee. If you have questions regarding youraccount or your Portfolio, please contact your financialadvisor or the Trustee. The Sponsor does not haveaccess to individual account information.

PORTFOLIO ADMINISTRATION

Portfolio Administration. The Portfolios are notmanaged funds and, except as provided in the TrustAgreement, Securities generally will not be sold orreplaced. The Sponsor may, however, direct thatSecurities be sold in certain limited circumstances toprotect the Portfol io based on advice from theSupervisor. These situations may include events suchas the issuer having defaulted on payment of any of itsoutstanding obligations or the price of a Security hasdeclined to such an extent or other credit factors existso that in the opinion of the Supervisor retention of theSecurity would be detrimental to the Portfolio. If a publictender offer has been made for a Security or a mergeror acquisition has been announced affecting a Security,the Trustee may either sell the Security or accept anoffer if the Supervisor determines that the sale orexchange is in the best interest of Unitholders. TheTrustee will distribute any cash proceeds to Unitholders.In addition, the Trustee may sell Securities to redeemUnits or pay Portfolio expenses or deferred salescharges. With respect to a Portfolio structured as agrantor trust for federal tax purposes, the Trustee mustreject any offer for securities or property other than cashin exchange for the Securities. If securities or propertyare acquired by a Portfolio, the Sponsor may direct theTrustee to sell the securities or property and distributethe proceeds to Unitholders or to accept the securitiesor property for deposit in the Portfolio. Should anycontract for the purchase of any of the Securities fail,the Sponsor will (unless substantially all of the moneysheld in the Portfol io to cover the purchase arereinvested in substitute Securities in accordance withthe Trust Agreement) refund the cash and sales charge

attributable to the failed contract to all Unitholders on orbefore the next Distribution Date.

Except with respect to the U.S. Defense Portfolio, theSponsor may direct the reinvestment of proceeds of thesale of Securities if the sale is the direct result of seriousadverse credit factors which, in the opinion of theSponsor, would make retention of the Securitiesdetrimental to your Portfolio. In such a case, theSponsor may, but is not obligated to, direct thereinvestment of sale proceeds in any other securitiesthat meet the criteria for inclusion in your Portfolio on theInitial Date of Deposit. The Sponsor may also instruct theTrustee to take action necessary to ensure that yourPortfolio continues to satisfy the qualifications of a RICand to avoid imposition of tax on undistributed incomeof the Portfolio.

When your Portfolio sells Securities, the compositionand diversity of the Securities in the Portfolio may bealtered. In order to obtain the best price for a Portfolio, itmay be necessary for the Supervisor to specifyminimum amounts (generally 100 shares) in whichblocks of Securit ies are to be sold. In effectingpurchases and sales of portfolio securities, the Sponsormay direct that orders be placed with and brokeragecommissions be paid to brokers, including brokerswhich may be affiliated with the Portfolios, the Sponsoror dealers participating in the offering of Units.

Pursuant to an exemptive order, your Portfolio maybe permitted to sell Securities to a new trust when itterminates if those Securities are included in the newtrust. The exemption may enable your Portfolio toeliminate commission costs on these transactions. Theprice for those securities will be the closing sale priceon the sale date on the exchange where the Securitiesare principally traded, as certified by the Sponsor.

Amendment of the Trust Agreement. TheTrustee and the Sponsor may amend the TrustAgreement without the consent of Unitholders tocorrect any provision which may be defective or tomake other provisions that will not materially adverselyaffect Unitholders (as determined in good faith by theSponsor and the Trustee). The Trust Agreement maynot be amended to increase the number of Units or

A-18

permit acquisit ion of securit ies in addition to orsubstitution for the Securities (except as provided in theTrust Agreement). The Trustee will notify Unitholders ofany amendment.

Termination. Your Portfolio will terminate on theMandatory Termination Date specified under “EssentialInformation” or upon the sale or other disposition of thelast Security held in the Portfolio. Your Portfolio may beterminated at any time with consent of Unitholdersrepresenting two-thirds of the outstanding Units or bythe Trustee when the value of the Portfolio is less than$500,000 ($3,000,000 if the value of the Portfolio hasexceeded $15,000,000) (the “Minimum TerminationValue”). Your Portfolio will be liquidated by the Trusteein the event that a sufficient number of Units of thePortfolio not yet sold are tendered for redemption bythe Sponsor, so that the net worth of the Portfoliowould be reduced to less than 40% of the value of theSecurities at the time they were deposited in thePortfolio. If your Portfolio is liquidated because of theredemption of unsold Units by the Sponsor, theSponsor will refund to each purchaser of Units theentire sales charge paid by such purchaser. TheTrustee may begin to sell Securities in connection witha Portfolio termination nine business days before, andno later than, the Mandatory Termination Date.Qualified Unitholders may elect an in kind distribution ofSecurities, provided that Unitholders may not requestan in kind distribution of Securities within 30 calendardays of a Portfolio’s termination. Any in kind distributionof Securities will be made in the manner and subject tothe restrictions described under “Rights of Unitholders--Redemption of Units”, provided that, in connectionwith an in kind distribution election more than 30calendar days pr ior to terminat ion, Unitholderstendering 1,000 or more Units of a Portfolio (or suchhigher amount as may be required by your broker-dealer or sel l ing agent) may request an in kinddistribution of Securities equal to the Redemption Priceper Unit on the date of tender. Unitholders will receive afinal cash distribution within a reasonable time after theMandatory Termination Date. All distributions will be netof Portfolio expenses and costs. Unitholders willreceive a f inal distr ibut ion statement fol lowing

termination. The Information Supplement containsfurther information regarding termination of yourPortfolio. See “Additional Information”.

TAXATION – GLOBAL TECHNOLOGY LEADERSPORTFOLIO, AMERICAN INNOVATION LEADERSPORTFOLIO, AND NEW WORLD LEADERSPORTFOLIO

This section summarizes some of the principal U.S.federal income tax consequences of owning Units of thePortfolios. Tax laws and interpretations are subject tochange, possibly with retroactive effect. This summarydoes not describe all of the tax consequences to alltaxpayers. For example, this summary generally doesnot describe your situation if you are a corporation, anon-U.S. person, a broker/dealer, a tax-exempt entity,financial institution, person who marks to market theirUnits or other investor with special circumstances. Inaddition, this section does not describe your alternativeminimum, state, local or foreign tax consequences ofinvesting in a Portfolio.

This federal income tax summary is based in part onthe advice of counsel to the Sponsor. The InternalRevenue Service could disagree with any conclusionsset forth in this section. In addition, our counsel was notasked to review the federal income tax treatment of theassets to be deposited in your Portfolio.

Additional information related to taxes is contained inthe Information Supplement. As with any investment,you should seek advice based on your individualcircumstances from your own tax advisor.

Portfolio Status. Your Portfolio intends to elect andto qualify annually as a RIC under the federal tax laws. Ifyour Portfolio qualifies under the tax law as a RIC anddistributes its income in the manner and amountsrequired by the RIC tax requirements, the Portfoliogenerally will not pay federal income taxes. But there isno assurance that the distributions made by yourPortfolio will eliminate all taxes for every year at the levelof your Portfolio.

Distributions. Portfolio distributions are generallytaxable. After the end of each year, you will receive a taxstatement reporting your Portfolio's distributions,including the amounts of ordinary income distributionsand capital gains dividends. Your Portfolio may maketaxable distributions to you even in periods during whichthe value of your Units has declined. Ordinary income

A-20

distributions are generally taxed at your federal tax ratefor ordinary income, however, as further discussedbelow, certain ordinary income distributions receivedfrom your Portfolio may be taxed, under current federallaw, at capital gains tax rates. Certain ordinary incomedividends on Units that are attributable to qualifyingdividends received by your Portfolio from certaincorporations may be reported by the Portfolio as beingeligible for the dividends received deduction forcorporate Unitholders provided certain holding periodrequirements are met. Income from the Portfolio andgains on the sale of your Units may also be subject to a3.8% federal tax imposed on net investment income ifyour adjusted gross income exceeds certain thresholdamounts, which currently are $250,000 in the case ofmarried couples filing joint returns and $200,000 in thecase of single individuals. In addition, your Portfolio maymake distributions that represent a return of capital fortax purposes to the extent of the Unitholder's basis inthe Units, and any additional amounts in excess of basiswould be taxed as a capital gain. Generally, you willtreat all capital gains dividends as long-term capitalgains regardless of how long you have owned yourUnits. The tax status of your distributions from yourPortfolio is not affected by whether you reinvest yourdistributions in additional Units or receive them in cash.The income from your Portfolio that you must take intoaccount for federal income tax purposes is not reducedby amounts used to pay a deferred sales charge, if any.The tax laws may require you to treat certaindistributions made to you in January as if you hadreceived them on December 31 of the previous year.

A distribution paid by your Portfolio reduces thePortfolio's net asset value per Unit on the date paid bythe amount of the distribution. Accordingly, a distributionpaid shortly after a purchase of Units by a Unitholderwould represent, in substance, a partial return of capital,however, it would be subject to income taxes.

Sale or Redemption of Units. If you sell orredeem your Units, you will generally recognize ataxable gain or loss. To determine the amount of thisgain or loss, you must subtract your adjusted tax basisin your Units from the amount you receive for the sale ofthe Units. Your initial tax basis in your Units is generally

equal to the cost of your Units, generally including salescharges. In some cases, however, you may have toadjust your tax basis after you purchase your Units.

Capital Gains and Losses and CertainOrdinary Income Dividends. Net capital gain equalsnet long-term capital gain minus net short-term capitalloss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than oneyear and is short-term if the holding period for the assetis one year or less. You must exclude the date youpurchase your Units to determine your holding period.However, if you receive a capital gain dividend from yourPortfolio and sell your Units at a loss after holding it forsix months or less, the loss will be recharacterized aslong-term capital loss to the extent of the capital gaindividend received. The tax rates for capital gainsrealized from assets held for one year or less aregenerally the same as for ordinary income.

In certain circumstances, ordinary income dividendsreceived by an individual Unitholder from a RIC such asyour Portfolio may be taxed at the same federal ratesthat apply to net capital gain (as discussed above),provided certain holding period requirements aresatisfied and provided the dividends are attributable toqualified dividend income received by the Portfolio itself.Qualified dividend income means dividends paid to aPortfolio (a) by domestic corporations, (b) by foreigncorporations that are either ( i ) incorporated in apossession of the United States or (ii) are eligible forbenefits under certain income tax treaties with theUnited States that include an exchange of informationprogram, or (c) with respect to stock of a foreigncorporation that is readily tradeable on an establishedsecurities market in the United States. Both the Portfolioand the Unitholder must meet certain holding periodrequirements to qualify Portfolio dividends for thistreatment. Income derived from investments inderivatives, fixed-income securities, U.S. real estateinvestment trusts, passive foreign investmentcompanies, and income received “in lieu of” dividends ina securities lending transactions generally is not eligiblefor treatment as qualified dividend income. If thequalified dividend income received by a Portfolio isequal to 95% (or a greater percentage) of the Portfolio's

A-21

gross income (exclusive of net capital gain) in anytaxable year, all of the ordinary income dividends paidby the Portfolio will be qualified dividend income. YourPortfolio will provide notice to its Unitholders of theamount of any distribution which may be taken intoaccount as qualified dividend income which is eligiblefor capital gains tax rates. There is no requirement thattax consequences be taken into account inadministering your Portfolio.

In Kind Distributions. Under certain circumstances,as described in this prospectus, you may receive an inkind distribution of Portfolio securities when you redeemyour Units. In general, this distribution will be treated as asale for federal income tax purposes and you willrecognize gain or loss, based on the value at that time ofthe securities and the amount of cash received, andsubject to certain limitations on the deductibility of lossesunder the tax law.

Rollovers and Exchanges. If you elect to haveyour proceeds from your Portfolio rolled over into afuture trust, it would generally be considered a sale forfederal income tax purposes and any gain on the salewill be treated as a capital gain, and, in general, any losswill be treated as a capital loss. However, any lossrealized on a sale or exchange will be disallowed to theextent that Units disposed of are replaced (includingthrough reinvestment of dividends) within a period of 61days beginning 30 days before and ending 30 daysafter disposition of Units or to the extent that theUnitholder, during such period, acquires or enters intoan option or contract to acquire, substantially identicalstock or securities. In such a case, the basis of theUnits acquired will be adjusted to reflect the disallowedloss. The deductibility of capital losses is subject toother limitations in the tax law.

Deductibility of Portfolio Expenses. Expensesincurred and deducted by your Portfolio will generallynot be treated as taxable income to you. In certaincases if your Portfolio is not considered “publiclyoffered” under the Internal Revenue Code of 1986, asamended (the “Code”), each U.S. Unitholder that iseither an individual, trust or estate will be treated ashaving received a taxable distribution from the Portfolioin the amount of that U.S. Unitholder's allocable share

of certain of the Portfolio's expenses for the calendaryear, and these fees and expenses will be treated asmiscellaneous itemized deductions of those U.S.Unitholders. The deductibility of expenses that arecharacterized as miscellaneous itemized deductions,which include investment expenses, is suspended fortax years beginning prior to January 1, 2026.

Foreign Investors. If you are a foreign investor (i.e.,an investor other than a U.S. citizen or resident or aU.S. corporation, partnership, estate or trust), generally,subject to applicable tax treaties, distributions to youfrom your Portfolio will be characterized as dividends forfederal income tax purposes (other than dividends thatyour Portfolio reports as capital gain dividends) and willbe subject to U.S. income taxes, including withholdingtaxes, subject to certain exceptions described below.You may be eligible under certain income tax treaties fora reduction in withholding rates. However, distributionsreceived by a foreign investor from your Portfolio thatare properly reported by the trust as capital gaindividends, interest-related dividends paid by thePortfolio from its qualified net interest income from U.S.sources and short-term capital gain dividends, may notbe subject to U.S. federal income taxes, includingwithholding taxes, provided that your Portfolio makescertain elections and certain other conditions are met.

The Foreign Account Tax Compliance Act(“FATCA”). A 30% withholding tax on your Portfolio'sdistributions generally applies if paid to a foreign entityunless: (i) if the foreign entity is a “foreign financialinstitution” as defined under FATCA, the foreign entityundertakes certa in due di l igence, report ing,withholding, and certification obligations, (ii) if theforeign entity is not a “foreign financial institution,” itidentifies certain of its U.S. investors or (iii) the foreignentity is otherwise excepted under FATCA. If requiredunder the rules above and subject to the applicabilityof any intergovernmental agreements between theUnited States and the relevant foreign country,withholding under FATCA may apply. Under existingregulations, FATCA withholding on gross proceedsfrom the sale of Units and capital gain distributionsfrom your Portfolio took effect on January 1, 2019;however, proposed U.S. tax regulations eliminate

A-22

FATCA withholding on such types of payments.Taxpayers generally may rely on these proposedTreasury Regulations until final Treasury Regulationsare issued. If withholding is required under FATCA on apayment related to your Units, investors that otherwisewould not be subject to withholding (or that otherwisewould be entitled to a reduced rate of withholding) onsuch payment generally will be required to seek arefund or credit from the IRS to obtain the benefit ofsuch exemption or reduction. Your Portfolio will notpay any additional amounts in respect of amountswithheld under FATCA. You should consult your taxadvisor regarding the effect of FATCA based on yourindividual circumstances.

Foreign Tax Credit. If your Portfolio invests in anyforeign securities, the tax statement that you receivemay include an item showing foreign taxes yourPortfolio paid to other countries. In this case, dividendstaxed to you will include your share of the taxes yourPortfolio paid to other countries. If more than 50% ofthe value of the Portfolio's total assets at the end of afiscal year is invested in foreign securities, the Portfoliomay elect to “pass-through” to the Unitholders theamount of foreign income tax paid by the Portfolio inlieu of deducting such amount in determining itsinvestment company taxable income. In such a case,Unitholders will be required (i) to include in grossincome, even though not actually received, theirrespective pro rata shares of the foreign income taxpaid by the Portfolio that are attributable to anydistributions they receive; and (ii) either to deduct theirpro rata share of foreign tax in computing their taxableincome or to use it (subject to various limitations) as aforeign tax credit against federal income tax (but notboth). No deduction for foreign tax may be claimed by anon-corporate Unitholder who does not itemizedeductions or who is subject to the alternative minimumtax. Unitholders may be unable to claim a credit for thefull amount of their proportionate shares of the foreignincome tax paid by the Portfol io due to certainlimitations that may apply. The Portfolio reserves theright not to pass-through to its Unitholders the amountof foreign income taxes paid by the Portfolio.

Backup Withholding. By law, your Portfolio mustwithhold as backup withholding a percentage (currently24%) of your taxable distributions and redemptionproceeds if you do not provide your correct socialsecurity or taxpayer identification number and certifythat you are not subject to backup withholding, or if theIRS instructs your Portfolio to do so.

Investors should consult their advisors concerningthe federal, state, local and foreign tax consequences ofinvesting in a Portfolio.

TAXATION – U.S. DEFENSE PORTFOLIO

This section summarizes some of the principal U.S.federal income tax consequences of owning Units of theU.S. Defense Portfolio which is structured as a grantortrust for federal tax purposes. Tax laws andinterpretations are subject to change, possibly withretroactive effect. This summary does not describe all ofthe tax consequences to all taxpayers. For example,this summary generally does not describe your situationif you are a corporation, a non-U.S. person, abroker/dealer, a tax-exempt entity, financial institution,person who marks to market their Units or otherinvestor with special circumstances. In addition, thissection does not describe the state, local or foreign taxconsequences of investing in the Portfolio.

This federal income tax summary is based in part onthe advice of counsel to the Sponsor. The InternalRevenue Service could disagree with any conclusionsset forth in this section. In addition, our counsel was notasked to review the tax treatment of the assets to bedeposited in your Portfolio.

As with any investment, you should seek advicebased on your individual circumstances from your owntax advisor.

Assets of the Portfolio. Your Portfolio is expectedto hold shares of stock in corporations that are treatedas equity for federal income tax purposes. It is possiblethat your Portfolio will also hold other assets, includingassets that are treated differently for federal income taxpurposes from those described above, in which caseyou will have federal income tax consequences differentfrom or in addition to those described in this section.

A-23

We refer to the assets held by your Portfol io as“Portfolio Assets”.

Portfolio Status. If your Portfolio is at all timesoperated in accordance with the documentsestablishing your Portfolio and certain requirements offederal income tax law are met, your Portfolio will not betaxed as a corporation for federal income tax purposes.As a Unit owner, you will be treated as the owner of apro rata portion of each of the Portfolio Assets, and assuch you will be considered to have received a pro ratashare of income (e.g., dividends and capital gains), ifany from each Portfolio Asset when such income wouldbe considered to be received by you if you directlyowned the Portfolio Assets. This tax treatment applieseven if you elect to have your distributions reinvestedinto additional Units. In addition, the income fromPortfolio Assets that you must take into account forfederal income tax purposes is not reduced by amountsused to pay sales charges or Portfolio expenses.

Your Tax Basis and Income or Loss UponDisposition. If you dispose of your Units or redeemyour Units for cash, you will generally recognize gain orloss. To determine the amount of this gain or loss, youmust subtract your adjusted tax basis in your Unitsdisposed of from your proceeds received in thetransaction. You also generally will recognize taxablegain or loss if your Portfolio disposes of Portfolio Assets.Your init ial tax basis in each Portfol io Asset isdetermined by apportioning the cost of your Units,including sales charges, among the Portfolio Assetsratably according to their values on the date you acquireyour Units. In certain circumstances, however, your taxbasis in certain Portfolio Assets must be adjusted afteryou acquire your Units.

Net capital gain equals net long-term capital gainminus net short-term capital loss for the taxable year.Capital gain or loss is long-term if the holding period forthe asset is more than one year and is short-term if theholding period for the asset is one year or less. Youmust exclude the date you purchase your Units todetermine your holding period. The tax rates for capitalgains realized from assets held for one year or less aregeneral ly the same as for ordinary income. Thedeductibility of capital losses is subject to limitations

under the Code, including generally a maximumdeduction against ordinary income of $3,000 per year.Income from the Portfolio and gains on the sale of yourUnits may also be subject to a 3.8% federal taximposed on net investment income if your adjustedgross income exceeds certain threshold amounts,which currently are $250,000 in the case of marriedcouples filing joint returns and $200,000 in the case ofsingle individuals.

Dividends from Stocks. Certain dividends receivedby non-corporate Unitholders with respect to the stocksin the Portfolio may qualify to be taxed at the samefederal rates that apply to net capital gain, providedcertain holding period requirements are satisfied. Theseare generally referred to as qualified dividends.

Dividends Received Deduction. Generally, adomestic corporation owning Units in the Portfolio maybe eligible for the dividends received deduction withrespect to such Unitholder's pro rata portion of certaintypes of dividends received by the Portfolio. However, acorporation generally will not be entitled to the dividendsreceived deduction with respect to dividends from mostforeign corporations.

Cash Distributions, Rollovers and Exchanges.If you receive cash when you redeem your Units or atyour Portfolio's termination or if you elect to direct thatthe cash proceeds you are deemed to receive when youredeem your Units or at your Portfolio's termination berolled into a future trust, it is considered a sale forfederal income tax purposes, and any gain on the salewill be treated as a capital gain, and, in general, any losswill be treated as a capital loss. However, any loss youincur in connection with the receipt or deemed receiptof cash, or in connection with the exchange of yourUnits of the Portfolio for units of another trust (deemedsale and subsequent deemed repurchase), will generallybe disallowed to the extent you acquire units of asubsequent trust and such subsequent trust hassubstantially identical assets under the wash saleprovisions of the Code. The deductibility of capitallosses is subject to other limitations in the tax law.

In Kind Distributions. Under certain circumstancesas described in this Prospectus, you may request an in

A-24

kind distribution of Portfolio Assets when you redeemyour Units. By electing to receive an in kind distribution,you will receive Portfolio Assets plus, possibly, cash. Yougenerally will not recognize gain or loss if you onlyreceive whole Portfolio Assets in exchange for theidentical amount of your pro rata portion of the samePortfolio Assets held by your Portfolio. However, if youalso receive cash in exchange for a Portfolio Asset or afractional portion of a Portfolio Asset, you will generallyrecognize gain or loss based on the difference betweenthe amount of cash you receive and your proportionaltax basis in such Portfolio Asset or fractional portion.

Limitations on the Deductibility of PortfolioExpenses. Generally, for federal income tax purposes,you must take into account your full pro rata share ofyour Portfolio's income, even if some of that income isused to pay Portfolio expenses. The deductibility ofexpenses that are characterized as miscellaneousitemized deductions, which include investmentexpenses, is suspended for tax years beginning prior toJanuary 1, 2026.

Foreign Investors. If you are a foreign investor (i.e.,an investor other than a U.S. citizen or resident or aU.S. corporation, partnership, estate or trust),distributions of dividends and interest from yourPortfolio generally are subject to U.S. federal incometaxes, including withholding taxes, unless certainconditions for exemption from U.S. taxation are met.Gains from the sale or redemption of your Units may notbe subject to U.S. federal income taxes if you are nototherwise subject to net income taxation in the UnitedStates. In the case of Units held by nonresident alienindividuals, foreign corporations or other non-U.S.persons, distributions by your Portfolio that are treatedas U.S. source income (e.g., dividends received onstocks of domestic corporations) will generally besubject to U.S. income taxation and withholding,subject to any applicable treaty. You should consult yourtax advisor with respect to the conditions you mustmeet in order to be exempt from U.S. taxation. Youshould also consult your tax advisor with respect toother U.S. tax withholding and reporting requirements.

FATCA. A 30% withholding tax on your Portfolio'sdistributions generally applies if paid to a foreign entity

unless: (i) if the foreign entity is a “foreign financialinstitution” as defined under FATCA, the foreign entityundertakes certain due di l igence, report ing,withholding, and certification obligations, (ii) if theforeign entity is not a “foreign financial institution,” itidentifies certain of its U.S. investors or (iii) the foreignentity is otherwise excepted under FATCA. If requiredunder the rules above and subject to the applicability ofany intergovernmental agreements between the UnitedStates and the relevant foreign country, withholdingunder FATCA may apply. Under existing regulations,FATCA withholding on gross proceeds from the sale ofUnits and capital gain distributions from your Portfoliotook effect on January 1, 2019; however, proposedU.S. tax regulations eliminate FATCA withholding onsuch types of payments. Taxpayers generally may relyon these proposed Treasury Regulations until finalTreasury Regulations are issued. If withholding isrequired under FATCA on a payment related to yourUnits, investors that otherwise would not be subject towithholding (or that otherwise would be entitled to areduced rate of withholding) on such payment generallywill be required to seek a refund or credit from the IRSto obtain the benefit of such exemption or reduction.We will not pay any additional amounts in respect ofamounts withheld under FATCA. You should consultyour tax advisor regarding the effect of FATCA basedon your individual circumstances.

Foreign Taxes. Some distributions or incomeearned by your Portfolio may be subject to foreignwithholding taxes. Any income withheld will still betreated as income to you. Under the grantor trust rules,you are considered to have paid directly your share ofany foreign taxes that are paid. Therefore, for U.S. taxpurposes, you may be entitled to a foreign tax credit ordeduction for those foreign taxes.

Backup Withholding. By law, your Portfolio mustwithhold as backup withholding a percentage (formerly24%) of your taxable distributions and redemptionproceeds if you do not provide your correct socialsecurity or taxpayer identification number and certify thatyou are not subject to backup withholding, or if theInternal Revenue Service instructs your Portfolio to do so.
