The trust seeks to provide above average totalreturn. There is no assurance the trust will achieveits objective.

PPRRIINNCCIIPPAALL IINNVVEESSTTMMEENNTT SSTTRRAATTEEGGYY

The trust consists of stocks selected by Eugene E.Peroni of Peroni Portfolio Advisors, Inc. (the “PortfolioConsultant”) through application of his proprietarymethod of technical analysis, the Peroni Method, his-torical quantitative analysis and fundamental analysis.Mr. Peroni initially screened stocks based on the fol-lowing criteria:

• companies with a longer-term history of pay-ing dividends with special consideration tothose companies that have historicallyincreased their dividends;

• companies with current annual dividendyields of 2.5% or higher;

• companies with cash flows that appear suffi-cient for such company to continue to paydividends; and

• companies with good longer-term earningsgrowth prospects.

Mr. Peroni narrowed this universe of stocksthrough application of the Peroni Method. From thesestocks, Mr. Peroni selected a final portfolio focusing onfinancial strength, prospects for revenue and earningsgrowth and sustainability of the dividend, among othercriteria. Dividends may be an important componentto total return.

Eugene E. Peroni Jr. has regularly published hisinsights in reports offering stock market forecasts andspecific stock recommendations for both short andlonger-term investments. Mr. Peroni regularly appearson CNBC, CBS MarketWatch, Nightly BusinessReport, Fox Business News and Bloomberg Radio,and has been quoted in publications such as The WallStreet Journal, The New York Times, U.S. News andWorld Report and Investors Business Daily.

Mr. Peroni began training in the field of technicalresearch at age 16 with his father, Eugene E. Peroni,Sr., who founded the Peroni Method more than 50years ago. Mr. Peroni has over 40 years of experiencein his field. The Peroni Method uses a bottom-upapproach, primarily emphasizing the technical meritsof individual stocks.

Mr. Peroni has a library of approximately 1,000hand-charted stocks that is the result of extensive tech-nical research and is regularly refreshed to include newopportunities gleaned through ticker tape analysis,news outlets, corporate developments and practicalobservations. Charts with attractive price architectureare noted and stocks are ranked and screened on a reg-ular basis. Historical characteristics are analyzed forprice and volume shifts and evaluations are made usingmoney flow and relative strength trends. Sector rela-tive strength is then determined by unbiased groupingsof attractive stocks. Portfolio construction progressesas weightings are determined by analyzing individualstock price behavior, economic factors, monetarytrends, psychological oscillators and investor psycholo-gy. Those stocks with the best technical characteristicsin strong or emerging leadership sectors are candidatesfor inclusion in the portfolio while also taking intoconsideration appropriate diversification.

The Peroni Method is a bottom-up approach tostock selection that is primarily based on technicalanalysis. The methodology examines a stock’s pricearchitecture, accumulation and distribution trends andrelative strength patterns, among other more subtletrading characteristics. This information is partly gath-ered and analyzed through hand drawn point and fig-ure charts which have been a part of the methodologyfor over half a century. While the Peroni Method isprimarily focused on the technical characteristics ofindividual stocks, economic, monetary, geopoliticaland sentiment factors at play in the market place arealso incorporated to identify leading stocks and sectors.

Technical analysis differs from fundamental analy-sis, which generally involves financial scrutiny of theissuing company and considers such factors as earningsprojections, P/E ratios, cash flow and other balancesheet data. The Peroni Method may be an investment

alternative to fundamental analysis. Mr. Peronibelieves that technical factors can help identify indus-try sector relative strength patterns that may play animportant role in investment success. The methodolo-gy allows an unconstrained approach to stock selec-tion, spanning all market caps and investment styles,i.e. growth and value.

The Peroni Method examines numerous techni-cal, psychological and fundamental data. The datamay include:

• a stock’s historical price architecture

• net money flow trends in individual stocks

• the relative behavior of a stock’s price per-formance compared to other stocks in thesame sector

• sentiment readings such as the volatility index

• fiscal and monetary factors

• geopolitical events and their impact on specif-ic sectors

The following table compares hypotheticalback-tested performance information for thestrategy employed by the trust and the actualperformance of the DJIASM in each of the yearslisted below (and as of the most recent month).These hypothetical back-tested returns do notguarantee and should not be used to predictfuture performance of the trust. Returns fromthe trust will differ from the hypothetical strate-gy returns for several reasons, including:

• total return figures shown do not reflectcommissions paid by the trust on thepurchase of securities or taxes you willincur;

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

• extraordinary market events that we havenot expected to be repeated and mayhave affected performance;

• the trust has a scheduled term longerthan one year;

• the trust may not be fully invested at alltimes or equally weighted in all securitiescomprising its strategy; and

• the trust often purchases or sells securitiesat prices different from the closing pricesused in buying and selling units.

You should note that the trust is notdesigned to parallel movements in any index, andit is not expected that it will do so. In fact, thetrust’s strategy underperformed its comparativeindex in certain years and we cannot guaranteethat the trust will outperform its related index

over the life of the trust or over consecutiverollover periods, if available.

Hypothetical back-tested performance is noguarantee of future results. Hypothetical back-tested performance of the Dow® Value TenStrategy securities (the “strategy securities”) ishypothetical (and does not represent any actualtrust), is shown for illustrative purposes only andis not intended to indicate the future performanceof any investment, including the trust. The strat-egy securities for a given year consist of the securi-ties selected by applying the strategy as of thebeginning of the period (and not the date thetrust actually sells units).

Securities are selected through application ofa strategy at a particular point in time and if asecurity which is a component of a strategy ismerged out of existence, de-listed or suffers asimilar fate during the period in which the strat-egy performance is being measured, such securi-ty will not be replaced by another security dur-ing that period. The strategy is not rebalancedduring each one year period and as a result thestocks used for determining hypothetical back-tested performance will not take into accountsubsequent changes to the indexes used as astarting point for the strategy.

Total return represents the sum of the changein market value of each group of securitiesbetween the first and last trading day of a periodplus the total dividends paid on each group ofsecurities during such period divided by the open-ing market value of each group of securities as ofthe first trading day of a period. Total return fig-ures shown above in the table assume that all divi-dends are reinvested semi-annually. Strategy fig-ures reflect the deduction of sales charges andexpenses but have not been reduced by estimatedbrokerage commissions and other transactioncosts paid by the trust in acquiring securities orany taxes incurred by investors.

Hypothetical back-tested returns are hypo-thetical, meaning that they do not representactual trading, and, thus, may not reflect materialeconomic and market factors, such as liquidityconstraints, that may have had an impact onactual decision making. The hypothetical back-tested performance is the retroactive applicationof the strategy designed with the full benefit ofhindsight.

The trust’s strategy begins with the DJIASM.The DJIASM consists of 30 U.S. stocks chosen bythe editors of The Wall Street Journal as beingrepresentative of the broad market and ofAmerican industry. Changes in the componentstocks of the DJIASM are made entirely by the edi-tors of The Wall Street Journal without consultingthe companies, the stock exchange or any officialagency. For the sake of continuity, changes aremade rarely.

The trust seeks to provide above averagetotal return. There is no assurance the trust willachieve its objective.

PPRRIINNCCIIPPAALL IINNVVEESSTTMMEENNTT SSTTRRAATTEEGGYY

The trust seeks to achieve its objective byinvesting in a diversified portfolio of stocks ofcompanies organized in Europe selected byCyrus J. Lawrence LLC (the “PortfolioConsultant”). Portfolio Consultant sought toidentify stocks of companies exhibiting improvingand sustainable earnings supported by attractiverelative stock valuations. Companies selected forinclusion in the portfolio are expected by thePortfolio Consultant to be leaders in their respec-tive industry, dominant regionally and recognizedas either established or emerging global competi-tors. The trust’s “European Select” strategy has adual focus of targeting companies that will bepotential beneficiaries of global accelerating eco-nomic growth but also companies geared towardsa sustainable European recovery.

The trust’s portfolio was selected from aninvestment universe that includes all equities trad-ed on the recognized registered exchanges of theEuropean region. This list includes large, midand small capitalization stocks representing acomprehensive cross section of the Europeaneconomy. The trust was constructed using acombination of top-down (macro analysis) andbottom-up (individual stock selection) criteria.Starting with a country and industry matrix, theframework of the portfolio was aligned with thePortfolio Consultant’s macro economic outlookwhile capturing a cross-section of the Europeaninvestment universe. Once the framework was

identified, the trust’s portfolio was selectedthrough comprehensive quantitative screeningand qualitative validation. The screening processsought to identify stocks of companies organizedin Europe that exhibit superior characteristicsaccording to multiple factors broken down asgrowth, valuation and market measures. Stockswere selected based on evidence of superior rela-tive earnings growth expectations coupled withstrong balance sheets and the expectation of accel-erating shareholder returns either through increas-ing dividends and/or share buybacks.

Under normal circumstances, the trust willinvest at least 80% of its assets in stocks of com-panies organized in European countries.

Notes to Portfolio

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

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

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

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

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

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

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

Level 1 Level 2 Level 3Common Stocks $ 148,818 $ - $ -

(2) The cost of the securities to the sponsor and the sponsor’s profit or (loss) (which is the difference between the cost of the securities to the spon-sor and the cost of the securities to the trust) are $148,856 and $(38), respectively.

(3) All investments are in securities issued by a foreign company.

Common stocks comprise 100.00% of the investments in the trust, broken down by country of organization as set forth below:

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

PPRRIINNCCIIPPAALL IINNVVEESSTTMMEENNTT SSTTRRAATTEEGGYY

The trust invests in a portfolio of stocks of for-eign companies selected using a specialized dividend-oriented strategy that seeks above average total return.We* selected the portfolio as of February 14, 2017using the following strategy:

• We begin with the companies listed in the S&PADR Index. The S&P ADR Index is based on thenon-U.S. stocks comprising the S&P Global 1200Index. The S&P ADR Index is made up of thosecompanies from the S&P Global 1200 Index thatoffer either Level II or Level III AmericanDepositary Receipts (ADRs), global shares, or ordi-nary shares in the case of Canadian equities. TheS&P Global 1200 Index covers 30 countries andconsists of seven regional components.

• From the S&P ADR Index, we select the threesecurities with the highest dividend yields in eachof the nine Global Industry Classification Standard(GICS®) sectors other than the Financials andReal Estate sectors and the three securities with thehighest dividend yields in the Financials and RealEstate GICS® sectors combined. Effectively, afterSeptember 1, 2016 the strategy seeks to treat thenew Real Estate GICS® sector as if it was stillpositioned under the Financials GICS® sector (asit was prior to September 1, 2016).

• We select those 30 stocks for the trust’s portfolioin approximately equal weightings.

The eleven industry sectors used in the strategy arethe GICS® sectors published by S&P Dow JonesIndices and MSCI Inc. Please note that we appliedthe strategy to select the portfolio at a particular time.If we create additional units of the trust after the trust’sinception date, the trust will purchase the securitiesoriginally selected by applying the strategy. This istrue even if a later application of the strategy wouldhave resulted in the selection of different securities. In

addition, companies which, based on publicly availableinformation as of two business days prior to the dateof this prospectus, are the target of an announced busi-ness combination which we expect will happen withinsix months of the date of this prospectus have beenexcluded from the universe of securities from whichthe trust’s securities are selected.

The following table compares hypotheticalback-tested performance information for the strat-egy employed by the trust and the actual perform-ance of the Standard & Poor’s ADR Index and theStandard & Poor’s 500 Index in each of the yearslisted below (and as of the most recent monthend). These hypothetical back-tested returns donot guarantee and should not be used to predictfuture performance of the trust. Returns from thetrust will differ from the hypothetical strategyreturns for several reasons, including:

• total return figures shown do not reflectcommissions paid by the trust on the pur-chase of securities or taxes you will incur;

• strategy returns are for calendar years (andthrough the most recent month), whiletrusts begin and end on various dates;

• extraordinary market events that we havenot expected to be repeated and mayhave affected performance;

• the trust has a scheduled term longerthan one year;

• the trust may not be fully invested at alltimes or equally weighted in all securitiescomprising its strategy; and

• the trust often purchases or sells securitiesat prices different from the closing pricesused in buying and selling units.

You should note that the trust is notdesigned to parallel movements in any index, andit is not expected that it will do so. In fact, thetrust’s strategy underperformed its comparativeindexes in certain years and we cannot guaranteethat the trust will outperform any index over thelife of the trust or over consecutive rollover peri-ods, if available.

Hypothetical back-test-ed performance of the International High 30Strategy (the “strategy securities”) is hypothetical(and does not represent any actual trust), is shownfor illustrative purposes only and is not intended toindicate the future performance of any investment,including the trust.

performance is being measured, such security willnot be replaced by another security during thatperiod. The strategy is not rebalanced during eachone year period and as a result the securities usedfor determining hypothetical back-tested perform-ance will not take into account subsequentchanges to the indexes used as a starting point forthe strategy.

Prior to the market close on August 31, 2016,there were ten GICS® sectors and after the mar-ket close on August 31, 2016, a new Real EstateGICS® sector was added, elevating its positionfrom under the Financials GICS® sector, bring-ing the total number of GICS® sectors to eleven.Prior to August 31, 2016, the InternationalHigh 30 Strategy selected three securities from(after the application of certain screens) each ofthe then existing ten GICS® sectors. AfterAugust 31, 2016, the International High 30Strategy selects the three securities from each ofthe nine GICS® sectors other than the Financialsand Real Estate sectors and three additional secu-rities from the Financials and Real Estate GICS®

sectors combined (for a total of 30 securities) afterthe application of certain screens. The hypotheti-cal back-tested performance for 2016 and earlierare based on the International High 30 Strategywith ten GICS® sectors.

Total return represents the sum of the changein market value of each group of securities betweenthe first and last trading day of a period plus thetotal dividends paid on each group of stocks duringsuch period divided by the opening market valueof each group of stocks as of the first trading day ofa period. Total return figures shown above in thetable assume that all dividends are reinvested semi-annually. Strategy figures reflect the deduction ofsales charges and expenses but have not beenreduced by estimated brokerage commissions andother transaction costs paid by the trust in acquir-ing securities or any taxes incurred by investors.

Hypothetical back-tested returns are hypo-thetical, meaning that they do not representactual trading, and, thus, may not reflect materi-al economic and market factors, such as liquidityconstraints, that may have had an impact onactual decision making. The hypothetical back-tested performance is the retroactive applicationof the strategy designed with the full benefit ofhindsight.

The trust strategy is based on the S&P ADRIndex. The S&P ADR Index is designed to trackthe S&P 700 Index. The S&P ADR Index onlyincludes securities that can be traded and settled inthe U.S. The index is made up of those compa-nies from the S&P 700 Index that offer eitherLevel II or Level III ADRs, global shares, or ordi-nary shares in the case of Canadian equities.(Level II and III ADRs are listed on U.S. securitiesexchanges or Nasdaq and must comply with cer-tain Securities and Exchange Commission disclo-sure requirements.) The S&P 700 Index is a sub-set of the S&P Global 1200 Index, representingthe non-US segment of global equity markets. Itis the S&P Global 1200 Index excluding the S&P500 Index stocks. The S&P Global 1200 Index isa composite index, comprised of seven regionaland country headline indices, many of which arethe accepted leaders in their local markets. TheS&P Global 1200 Index covers 30 countries andconsists of seven regional components.

The indexes are unmanaged, not subject tofees, and not available for direct investment.

The strategy is derived from stocks containedin the S&P ADR Index. S&P Dow JonesIndices, a division of the S&P Global Inc., pub-lisher of the S&P ADR Index, is not affiliatedwith us and has not participated in creating thetrust or selecting the securities for the trust, norhave they reviewed or approved of any of theinformation contained herein.

PPRRIINNCCIIPPAALL IINNVVEESSTTMMEENNTT SSTTRRAATTEEGGYY

The trust seeks to achieve its objective byinvesting in a portfolio primarily consisting ofcommon stocks of large capitalization companies(defined as companies with capitalizations withinthe collective range of the Russell 1000® andS&P 500 Indices as of the trust’s inception)selected by Hartford Investment ManagementCompany (“HIMCO”). In selecting the portfo-lio, HIMCO sought to achieve the lowest amountof expected volatility compared to the broad U.S.equity market over the life of the trust subject toa set of reasonable constraints related to qualityand dividend yield designed by HIMCO. Lowvolatility stocks tend to have lower risk profilesthan the equity market in general. Investing inlow volatility stocks may not protect the trustfrom market declines and may reduce the trust’sparticipation in market gains.

HIMCO used a structured quantitativeapproach for its stock selection focusing on threemain characteristics: minimum volatility, qualityand dividend yield. From a minimum volatilityperspective, the process sought to identify a port-folio of stocks with lower expected volatility thanthe broader U.S. equity market. This analysisconsidered a stock’s beta, as well as its idiosyncrat-ic risk determined by HIMCO.

on solid balance sheets, high quality earnings, andattractive growth prospects (e.g. margin expan-sion, asset quality, low leverage, etc.). This analy-sis also considered the impact of potential corpo-rate events that may alter a company’s future fun-damentals. Finally, from a dividend yield per-spective, the process focused on stocks of compa-nies with above average dividend yield. Finalstock selection was based primarily on the overallportfolio from the minimum volatility perspectivewith consideration of the quality and dividendyield perspectives. In selecting the trust’s portfo-lio, HIMCO also considered the portfolio’s sectorexposures relative to custom sector classificationsdefined by HIMCO (based on Russell Industryclassifications). The trust’s sector weightings mayvary significantly from the sector weightings ofthe Russell 1000® or S&P 500 Indices.

This example helps you compare the cost of this trustwith other unit trusts and mutual funds. In the example weassume that the expenses do not change and that the trust’sannual return is 5%. Your actual returns and expenses willvary. Based on these assumptions, you would pay theseexpenses for every $10,000 you invest in the trust:

1 year $3663 years $9175 years $1,49510 years $3,068

This example assumes that you continue to followthe trust strategy and roll your investment, including alldistributions, into a new series of the trust each year sub-ject to a reduced rollover sales charge of 1.95%.

The following table compares hypotheticalback-tested performance information for the strate-gy employed by the trust, the High 50® DividendStrategy, the International High 30 DividendStrategy, and the actual performance of the Standard& Poor’s 500 Index in each of the years listed (andas of the most recent month end). These hypotheti-cal returns do not guarantee and should not be usedto predict future performance of the trust. Returnsfrom the trust will differ from the hypotheticalback-tested strategy returns for several reasons,including:

• total return figures shown do not reflectcommissions paid by the trust on the pur-chase of securities or taxes you will incur;

• strategy returns are for calendar years (andthrough the most recent month), whiletrusts begin and end on various dates;

• extraordinary market events that we havenot expected to be repeated and may haveaffected performance;

• the trust has a scheduled term longer thanone year;

• the trust may not be fully invested at alltimes or equally weighted in all securitiescomprising its strategy; and

• the trust often purchases or sells securitiesat prices different from the closing pricesused in buying and selling units.

You should note that the trust is not designedto parallel movements in any index, and it is notexpected that it will do so. In fact, the trust’s strate-gy underperformed its comparative indexes in cer-tain years and we cannot guarantee that the trustwill outperform any index over the life of the trustor over consecutive rollover periods, if available.

Hypothetical back-tested performance is noguarantee of future results. Hypothetical back-test-ed performance of the trust strategy (the StrategicHigh 80 Dividend Strategy), High 50® DividendStrategy and International High 30 DividendStrategy securities (the “strategy securities”) is hypo-thetical (and does not represent any actual trust), isshown for illustrative purposes only and is notintended to indicate the future performance of anyinvestment, including the trust. The strategy securi-ties for a given year consist of the securities selectedby applying the strategy as of the beginning of theperiod (and not the date the trust actually sellsunits). The hypothetical back-tested past perform-ance of the Strategic High 80 Dividend Strategysecurities for 1 of the 15 periods shown are theresult of extraordinary market events and are notexpected to be repeated.

Securities are selected through application of astrategy at a particular point in time and if a securi-ty which is a component of a strategy is merged outof existence, de-listed or suffers a similar fate duringthe period in which the strategy performance isbeing measured, such security will not be replacedby another security during that period. The strategyis not rebalanced during each one year period and asa result the stocks used for determining hypotheticalback-tested performance will not take into accountsubsequent changes to the indexes used as a startingpoint for the strategy.

Prior to the market close on August 31, 2016,there were ten GICS® sectors and after the marketclose on August 31, 2016, a new Real Estate GICS®

sector was added, elevating its position from underthe Financials GICS® sector, bringing the totalnumber of GICS® sectors to eleven. Prior toAugust 31, 2016, the Strategic High 80 Strategyselected eight securities from (after the application ofcertain screens) each of the then existing ten GICS®

sectors. After August 31, 2016, the Strategic High80 Strategy selects eight securities from each of thenine GICS® sectors other than the Financials andReal Estate sectors and eight additional securities

from the Financials and Real Estate GICS® sectorscombined (for a total of 80 securities) after the appli-cation of certain screens. The hypothetical back-test-ed performance for 2016 and earlier are based on theStrategic High 80 Strategy with ten GICS® sectors.

Total return represents the sum of the change inmarket value of each group of securities between thefirst and last trading day of a period plus the totaldividends paid on each group of securities duringsuch period divided by the opening market value ofeach group of securities as of the first trading day ofa period. Total return shown in the table above fig-ures assume that all dividends are reinvested semi-annually. Strategy figures reflect the deduction ofsales charges and expenses but have not beenreduced by estimated brokerage commissions andother transaction costs paid by the trust in acquiringsecurities or any taxes incurred by investors.

Hypothetical back-tested returns are hypotheti-cal, meaning that they do not represent actual trad-ing, and, thus, may not reflect material economicand market factors, such as liquidity constraints,that may have had an impact on actual decisionmaking. The hypothetical performance is theretroactive application of the strategy designed withthe full benefit of hindsight.

HHOOWW TTOO BBUUYY UUNNIITTSS

You can buy units of a trust on any businessday the New York Stock Exchange is open bycontacting your financial professional. Unitprices are available daily on the Internet atwwwwww..AAAAMMlliivvee..ccoomm.. The public offering price ofunits includes:

• the net asset value per unit plus

• organization costs plus

• the sales fee.

The “net asset value per unit” is the value ofthe securities, cash and other assets in your trustreduced by the liabilities of your trust divided bythe total units or your trust outstanding. Weoften refer to the public offering price of units asthe “offer price” or “purchase price.” The offerprice will be effective for all orders received priorto the close of regular trading on the New YorkStock Exchange (normally 4:00 p.m. Easterntime). If we receive your order prior to the closeof regular trading on the New York StockExchange or authorized financial professionalsreceive your order prior to that time and properlytransmit the order to us by the time that we des-ignate, then you will receive the price computedon the date of receipt. If we receive your orderafter the close of regular trading on the New YorkStock Exchange, if authorized financial profes-sionals receive your order after that time or iforders are received by such persons and are nottransmitted to us by the time that we designate,then you will receive the price computed on thedate of the next determined offer price providedthat your order is received in a timely manner onthat date. It is the responsibility of the author-ized financial professional to transmit the ordersthat they receive to us in a timely manner.

Certain broker-dealers may charge a transactionor other fee for processing unit purchase orders.

VVaalluuee ooff tthhee SSeeccuurriittiieess.. We determine thevalue of the securities as of the close of regulartrading on the New York Stock Exchange on eachday that exchange is open. We generally deter-mine the value of securities using the last sale pricefor securities traded on a national securitiesexchange. For this purpose, the trustee providesus closing prices from a reporting service approvedby us. In some cases we will price a security basedon its fair value after considering appropriate fac-tors relevant to the value of the security. We willonly do this if a security is not principally tradedon a national securities exchange or if the marketquotes are unavailable or inappropriate.

We determined the initial prices of the securi-ties shown under each “Portfolio” section in thisprospectus as described above at the close of regu-lar trading on the New York Stock Exchange onthe business day before the date of this prospectus.On the first day we sell units we will compute theunit price as of the close of regular trading on theNew York Stock Exchange or the time the registra-tion statement filed with the Securities andExchange Commission becomes effective, if later.

OOrrggaanniizzaattiioonn CCoossttss.. During the initial offer-ing period, part of the value of the units repre-sents an amount that will pay the costs of creatingyour trust. These costs include the costs ofpreparing the registration statement and legaldocuments, a portfolio consultant’s security selec-tion fee (if any), federal and state registration fees,the initial fees and expenses of the trustee and theinitial audit. Your trust will sell securities toreimburse us for these costs at the end of the ini-tial offering period or after six months, if earlier.The value of your units will decline when yourtrust pays these costs.

TTrraannssaaccttiioonnaall SSaalleess FFeeee.. You pay a fee in con-nection with purchasing units. We refer to thisfee as the “transactional sales fee.” The transac-tional sales fee has both an initial and a deferredcomponent and equals 2.45% of the public offer-ing price per unit based on a $10 public offeringprice per unit. This percentage amount of thetransactional sales fee is based on the unit priceon your trust’s inception date. The transactionalsales fee equals the difference between the totalsales fee and the creation and development fee.As a result, the percentage and dollar amount ofthe transactional sales fee will vary as the publicoffering price per unit varies. The transactionalsales fee does not include the creation and devel-opment fee which is described under “Fees andExpenses” for your trust.

The maximum sales fee equals 2.95% of thepublic offering price per unit at the time of pur-chase. You pay the initial sales fee at the time youbuy units. The initial sales fee is the differencebetween the total sales fee percentage (maximumof 2.95% of the public offering price per unit)and the sum of the remaining fixed dollardeferred sales fee and the total fixed dollar cre-ation and development fee. The initial sales feewill be approximately 1.00% of the public offer-ing price per unit depending on the public offer-ing price per unit. The deferred sales fee is fixedat $0.145 per unit. Your trust pays the deferredsales fee in equal monthly installments asdescribed under “Fees and Expenses” for yourtrust. If you redeem or sell your units prior tocollection of the total deferred sales fee, you willpay any remaining deferred sales fee uponredemption or sale of your units.

If you purchase units after the last deferredsales fee payment has been assessed, the secondarymarket sales fee is equal to 2.95% of the publicoffering price and does not include deferred pay-

ments (i.e. unitholders who buy in the secondarymarket after collection of the deferred sales feesare not charged deferred sales fees).

MMiinniimmuumm PPuurrcchhaassee.. The minimum amountyou can purchase appears under “EssentialInformation” for your trust, but such amountsmay vary depending on your selling firm.

RReedduucciinngg YYoouurr SSaalleess FFeeee. We offer a variety ofways for you to reduce the fee you pay. It is yourfinancial professional’s responsibility to alert us ofany discount when you order units. Except asexpressly provided herein, you may not combinediscounts. Since the deferred sales fee and thecreation and development fee are fixed dollaramounts per unit, your trust must charge thesefees per unit regardless of any discounts.However, if you are eligible to receive a discountsuch that your total sales fee is less than the fixeddollar amounts of the deferred sales fee and thecreation and development fee, we will credit youthe difference between your total sales fee andthese fixed dollar fees at the time you buy units.

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

If you purchase: Your fee will be:

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

We apply these fees as a percent of the publicoffering price per unit at the time of purchase.The breakpoints will be adjusted to take into con-sideration purchase orders stated in dollars whichcannot be completely fulfilled due to the require-ments that only whole units be issued.

You aggregate initial offering period unitorders submitted by the same person for units ofany of the trusts we sponsor on any single dayfrom any one broker-dealer to qualify for a pur-chase level. If you purchase initial offering periodunits that qualify for the fee account orrollover/exchange discount described below andalso purchase additional initial offering periodunits on a single day from the same broker-dealerthat do not qualify for the fee account orrollover/exchange discount, you aggregate all ini-tial offering period units purchased for purposes ofdetermining the applicable breakpoint level in thetable above on the additional units, but such addi-tional units will not qualify for the fee account orrollover/exchange discount described below.Secondary market unit purchases are not aggregat-ed with initial offering period unit purchases forpurposes of determining the applicable breakpointlevel.

Fee Accounts. Investors may purchase unitsthrough registered investment advisers, certifiedfinancial planners or registered broker-dealers whoin each case either charge investor accounts (“FeeAccounts”) periodic fees for brokerage services,financial planning, investment advisory or assetmanagement services, or provide such services inconnection with an investment account for whicha comprehensive “wrap fee” charge (“Wrap Fee”)is imposed. You should consult your financial

advisor to determine whether you can benefitfrom these accounts. To purchase units in theseFee Accounts, your financial advisor must pur-chase units designated with one of the FeeAccount CUSIP numbers, if available. Pleasecontact your financial advisor for more informa-tion. If units are purchased for a Fee Accountand the units are subject to a Wrap Fee in suchFee Account (i.e., the trust is “Wrap Fee Eligible”)then investors may be eligible to purchase units inthese Fee Accounts that are not subject to thetransactional sales fee but will be subject to thecreation and development fee that is retained bythe sponsor. For example, this table illustrates thesales fee you will pay as a percentage of the initial$10 public offering price per unit (the percentagewill vary with the unit price).

The discounted pub-lic offering price per unit for these transactions isequal to the regular public offering price per unitless 1.00%. However, if you invest redemption ortermination proceeds of $500,000 or more inunits, the maximum sales fee on your units will belimited to the maximum sales fee for the applica-ble amount invested in the table under “LargePurchases” above. To qualify for this discount, thetermination or redemption proceeds used to pur-chase units of a trust offered in this prospectusmust be derived from a transaction that occurredwithin 30 calendar days of your purchase of unitsof a trust offered in this prospectus.

Please note that if you purchase units of atrust in this manner using redemption proceedsfrom trusts which assess the amount of anyremaining deferred sales fee at redemption, youshould be aware that any deferred sales feeremaining on these units will be deducted fromthose redemption proceeds. These discountsapply only to initial offering period purchases.

Dividend Reinvestment Plan. We do notcharge any sales fee when you reinvest distribu-tions from your trust into additional units of yourtrust. This sales fee discount applies to initialoffering period and secondary market purchases.Since the deferred sales fee and the creation anddevelopment fee are fixed dollar amounts perunit, your trust must charge these fees per unitregardless of this discount. If you elect the distri-bution reinvestment plan, we will credit you withadditional units with a dollar value sufficient tocover the amount of any remaining deferred salesfee or creation and development fee that will becollected on such units at the time of reinvest-ment. The dollar value of these units will fluctu-ate over time.

You can request an in-kind distribution ofthe securities underlying your units if you tenderat least 2,500 units for redemption (or suchother amount as required by your financial pro-fessional’s firm).

RRoolllloovveerr OOppttiioonn.. Your trust’s strategy may bea long-term investment strategy designed to befollowed on an annual basis. You may achievemore consistent long-term investment results byfollowing the strategy. As part of the strategy, wecurrently intend to offer a subsequent series ofyour trust for a rollover when the current trustterminates. When your trust terminates you willhave the option to (1) participate in a rolloverand have your units reinvested into a subsequenttrust series through a cash rollover as described in

this section, (2) receive an in-kind distribution ofsecurities or (3) receive a cash distribution.

If you elect to participate in a rollover, yourunits will be redeemed on your trust’s terminationdate. As the redemption proceeds become avail-able, the proceeds (including dividends) will beinvested in a new trust series, if available, at thepublic offering price for the new trust. Thetrustee will attempt to sell securities to satisfy theredemption as quickly as practicable on the termi-nation date. We do not anticipate that the saleperiod will be longer than one day, however, cer-tain factors could affect the ability to sell thesecurities and could impact the length of the saleperiod. The liquidity of any security depends onthe daily trading volume of the security and theamount available for redemption and reinvest-ment on any day.

We intend to make subsequent trust seriesavailable for sale at various times during the year.Of course, we cannot guarantee that a subsequenttrust or sufficient units will be available or thatany subsequent trusts will offer the same invest-ment strategies or objectives as current trusts. Wecannot guarantee that a rollover will avoid anynegative market price consequences resulting fromtrading large volumes of securities.

DDiissttrriibbuuttiioonnss. Your trust generally pays dis-tributions of its net investment income alongwith any excess capital on each distribution dateto unitholders of record on the preceding recorddate. If your trust is a “grantor trust” for federaltax purposes, the trust will generally only make adistribution if the total cash held for distributionequals at least 0.1% of the trust’s net asset valueas determined under the trust agreement. Therecord and distribution dates and the tax statusare shown under “Essential Information” in the“Investment Summary” section of this prospectusfor your trust. In some cases, your trust mightpay a special distribution if it holds an excessiveamount of cash pending distribution. For exam-ple, this could happen as a result of a merger orsimilar transaction involving a company whosestock is in your portfolio. Your trust will alsogenerally make required distributions or distribu-tions to avoid imposition of tax at the end ofeach year if it is structured as a “regulated invest-ment company” for federal tax purposes. Theamount of your distributions will vary from timeto time as companies change their dividends andother income distributions or trust expenseschange.

When your trust receives dividends and otherincome distributions from a portfolio security, thetrustee credits such payments to the trust’saccounts. In an effort to make relatively regularincome distributions, if your trust is a “regulatedinvestment company” for tax purposes and makesmonthly distributions, your trust’s monthly

income distribution is equal to one twelfth of theestimated net annual income distributions to bereceived by your trust after deduction of trustoperating expenses. Because a trust does notreceive income distributions from the portfoliosecurities at a constant rate throughout the year,the income distributions to unitholders from sucha trust may be more or less than the amount cred-ited to your trust accounts as of the record date.For the purpose of minimizing fluctuation inincome distributions, the trustee is authorized toadvance such amounts as may be necessary toprovide income distributions of approximatelyequal amounts. The trustee will be reimbursed,without interest, for any such advances fromavailable income received by a trust on the ensu-ing record date.

EEssttiimmaatteedd AAnnnnuuaall DDiissttrriibbuuttiioonnss.. The estimat-ed net annual distributions for your trust areshown under “Essential Information” section ofthis prospectus related to your trust. We general-ly base the estimate of the income your trust mayreceive on annualizing the most recent ordinarydividend declared by an issuer (or adding themost recent interim and final dividends declaredfor certain foreign issuers) and/or on scheduledincome payments. However, dividend conven-tions for certain companies and/or certain coun-tries differ from those typically used in theUnited States and in certain instances, dividendspaid or declared over several years or other peri-ods were used to estimate annual distributions.Due to this and various other factors, actual divi-dends and other income distributions received byyour trust will most likely differ from the mostrecent annualized dividends or scheduled incomepayments. The actual net annual distributionsyou will receive will vary with changes in yourtrust’s fees and expenses, in dividends and otherincome distributions received and with the saleof securities.

All investments involve risk. This sectiondescribes the main risks that can impact the valueof the securities in your portfolio. You shouldunderstand these risks before you invest. If thevalue of the securities falls, the value of your unitswill also fall. We cannot guarantee that your trustwill achieve its objective or that your investmentreturn will be positive over any period.

MMaarrkkeett RRiisskk.. Market risk is the risk that thevalue of the securities in your trust will fluctuate.This could cause the value of your units to fallbelow your original purchase price. Market valuefluctuates in response to various factors. Thesecan include changes in interest rates, inflation, thefinancial condition of a security’s issuer, percep-tions of the issuer, or ratings on a security. Eventhough we supervise your portfolio, you shouldremember that we do not manage your portfolio.Your trust will not sell a security solely because themarket value falls as is possible in a managed fund.

DDiivviiddeenndd PPaayymmeenntt RRiisskk.. Dividend paymentrisk is the risk that an issuer of a security isunwilling or unable to pay income on a security.Stocks represent ownership interests in the issuersand are not obligations of the issuers. Commonstockholders have a right to receive dividends onlyafter the company has provided for payment of itscreditors, bondholders and preferred stockholders.

Common stocks do not assure dividend pay-ments. Dividends are paid only when declared byan issuer’s board of directors and the amount ofany dividend may vary over time.

SSttrraatteeggyy CCoorrrreellaattiioonn RRiisskk.. Strategy correlationrisk is the risk that your trust’s performance willnot sufficiently correspond with the hypotheticalback-tested performance of your trust’s investmentstrategy, if any. This risk applies to your trust ifthe “Investment Summary” section for your trustin this prospectus includes “Hypothetical Back-tested Performance Information.” This can hap-pen for reasons such as:

• the impracticability of owning each ofthe strategy stocks with the exact weight-ings at a given time,

• strategy performance is based on a calen-dar year strategy while trusts may be cre-ated at various times during the year andgenerally have 15 month terms,

• your trust may not be fully invested at alltimes, and

• trust fees and expenses.

Hypothetical back-tested performance is notactual past performance of this or any trust.Hypothetical back-tested performance is based onapplication of a trust’s investment strategy as of aparticular time.

SSmmaallll aanndd MMiidd--SSiizzee CCoommppaanniieess.. Your trustmay invest in securities issued by small and mid-size companies. The share prices of these com-panies are often more volatile than those of larg-er companies as a result of several factors com-mon to many such issuers, including limitedtrading volumes, products or financial resources,management inexperience and less publicly avail-able information.

Your trust may invest significantly in securitiesof ccoonnssuummeerr pprroodduuccttss aanndd sseerrvviicceess companies.These companies manufacture or sell various con-sumer products and/or services. General risks ofthese companies include the general state of theeconomy, intense competition and consumerspending trends. A decline in the economy whichresults in a reduction of consumers’ disposableincome can negatively impact spending habits.Competitiveness in the retail industry will requirelarge capital outlays for the installation of auto-mated checkout equipment to control inventory,track the sale of items and gauge the success ofsales campaigns.

Capital goodscompanies may also be significantly affected byoverall capital spending levels, economic cycles,technical obsolescence, delays in modernization,limitations on supply of key materials, labor rela-tions, government regulations, government con-tracts and ecommerce initiatives. Furthermore,

certain companies involved in the industry havealso faced scrutiny for alleged accounting irregu-larities that may have led to the overstatement oftheir financial results, and other companies in theindustry may face similar scrutiny.

Industrials companies may also be affected byfactors more specific to their individual industries.Industrial machinery manufacturers may be sub-ject to declines in commercial and consumerdemand and the need for modernization.Aerospace and defense companies may be influ-enced by decreased demand for new equipment,aircraft order cancellations, disputes over or abili-ty to obtain or retain government contracts, orchanges in government budget priorities, changesin aircraft-leasing contracts and cutbacks in prof-itable business travel. The number of housingstarts, levels of public and non-residential con-struction including weakening demand for newoffice and retail space, and overall constructionspending may adversely affect construction mate-rials and equipment manufacturers.

The trust is therefore subject tocertain risks associated specifically with Europe.A significant number of countries in Europe aremember states in the European Union, and themember states no longer control their own mon-etary policies by directing independent interestrates for their currencies. In these memberstates, the authority to direct monetary policiesincluding money supply and official interestrates for the Euro is exercised by the EuropeanCentral Bank. Furthermore, the European sov-ereign debt crisis and the related austerity meas-ures in certain countries have had, and continueto have, a significant impact on the economiesof certain European countries and their futureeconomic outlooks.

FFoorreeiiggnn IIssssuueerr RRiisskk.. An investment in securi-ties of foreign issuers involves certain risks that aredifferent in some respects from an investment insecurities of domestic issuers. These include risksassociated with future political and economicdevelopments, international trade conditions, for-eign withholding taxes, liquidity concerns, curren-cy fluctuations, volatility, restrictions on foreigninvestments and exchange of securities, potentialfor expropriation of assets, confiscatory taxation,difficulty in obtaining or enforcing a court judg-ment, potential inability to collect when a compa-ny goes bankrupt and economic, political orsocial instability. Moreover, individual foreigneconomies may differ favorably or unfavorablyfrom the U.S. economy for reasons including dif-ferences in growth of gross domestic product,rates of inflation, capital reinvestment, resources,self-sufficiency and balance of payments positions.There may be less publicly available informationabout a foreign issuer than is available from adomestic issuer as a result of different accounting,auditing and financial reporting standards. Someforeign markets are less liquid than U.S. marketswhich could cause securities to be bought at ahigher price or sold at a lower price than wouldbe the case in a highly liquid market.

Securities of certain foreign issuers may bedenominated or quoted in currencies other thanthe U.S. dollar. Foreign issuers also make pay-ments and conduct business in foreign currencies.Many foreign currencies have fluctuated widely invalue against the U.S. dollar for various economicand political reasons. Changes in foreign curren-cy exchange rates may affect the value of foreignsecurities and income payments. Generally, whenthe U.S. dollar rises in value against a foreign cur-rency, a security denominated in that currencyloses value because the currency is worth fewerU.S. dollars. Conversely, when the U.S. dollardecreases in value against a foreign currency, a

security denominated in that currency gains valuebecause the currency is worth more U.S. dollars.The U.S. dollar value of income payments on for-eign securities will fluctuate similarly withchanges in foreign currency values.

Certain foreign securities may be held in theform of American Depositary Receipts (“ADRs”),Global Depositary Receipts (“GDRs”), or othersimilar receipts. Depositary receipts representreceipts for foreign securities deposited with acustodian (which may include the trustee of yourtrust). Depository receipts may not be denomi-nated in the same currency as the securities intowhich they may be converted. ADRs typicallytrade in the U.S. in U.S. dollars and are regis-tered with the Securities and ExchangeCommission. GDRs are similar to ADRs, butGDRs typically trade outside of the U.S. andoutside of the country of the issuer in the curren-cy of the country where the GDR trades.Depositary receipts generally involve most of thesame types of risks as foreign securities helddirectly but typically also involve additionalexpenses associated with the cost of the custodi-an’s services. Some depositary receipts may expe-rience less liquidity than the underlying securitiestraded in their home market. Certain depositaryreceipts are unsponsored (i.e. issued without theparticipation or involvement of the issuer of theunderlying security). The issuers of unsponsoreddepositary receipts are not obligated to discloseinformation that may be considered material inthe U.S. Therefore, there may be less informa-tion available regarding these issuers which canimpact the relationship between certain informa-tion impacting a security and the market value ofthe depositary receipts.

In addition, litigationregarding any of the issuers of the securities or ofthe industries represented by these issuers maynegatively impact the share prices of these securi-ties.

YYoouurr TTrruusstt.. Your trust is a unit investmenttrust registered under the Investment CompanyAct of 1940. We created your trust under a trustagreement between Advisors Asset Management,Inc. (as depositor/sponsor, evaluator and supervi-sor) and The Bank of New York Mellon (astrustee). To create your trust, we deposited secu-rities with the trustee (or contracts to purchasesecurities along with an irrevocable letter of creditor other consideration to pay for the securities).In exchange, the trustee delivered units of yourtrust to us. Each unit represents an undividedinterest in the assets of your trust. These unitsremain outstanding until redeemed or until yourtrust terminates. At the close of the New YorkStock Exchange on your trust’s inception date, thenumber of units may be adjusted so that the pub-lic offering price per unit equals $10. The num-

ber of units and fractional interest of each unit inyour trust will increase or decrease to the extentof any adjustment.

CChhaannggiinngg YYoouurr PPoorrttffoolliioo.. Your trust is not amanaged fund. Unlike a managed fund, wedesigned your portfolio to remain relatively fixed.Your trust will generally buy and sell securities:

• to pay expenses,

• to issue additional units or redeem units,

• to take actions in response to certain cor-porate actions and other events impactingportfolio securities,

• in limited circumstances to protect thetrust,

• to make required distributions or avoidimposition of taxes on the trust, or

• as permitted by the trust agreement.

When your trust sells securities, the compo-sition and diversification of the securities in theportfolio may be altered. If a public tender offerhas been made for a security or a merger, acqui-sition or similar transaction has been announcedaffecting a security, the sponsor may direct thetrustee to sell the security or accept a tenderoffer if the supervisor determines that the actionis in the best interest of unitholders. The trusteewill distribute any available cash proceeds tounitholders.

If an offer by the issuer of any of the portfo-lio securities or any other party is made to issuenew securities, or to exchange securities, for trustportfolio securities, the trustee will reject the offerunless your trust is a “regulated investment com-pany” for tax purposes (see “EssentialInformation—Tax Structure” in the “Investment

Summary” section for your trust in this prospec-tus). If your trust is a “regulated investment com-pany” for tax purposes and an offer by the issuerof any of the portfolio securities or any otherparty is made to issue new securities, or toexchange securities, for trust portfolio securities,the trustee may either vote for or against, oraccept or reject, any offer for new or exchangedsecurities or property in exchange for a trust port-folio security at the direction of the sponsor.

If any issuance, exchange or substitution ofnew or exchanged securities or property inexchange for a trust portfolio security occurs(regardless of any action or rejection by a trust),any securities and/or property received will bedeposited into the trust and will be promptly soldby the trustee pursuant to the sponsor’s direction,unless the sponsor advises the trustee to keep suchsecurities or property.

If any contract for the purchase of securitiesfails, the sponsor will refund the cash and sales feeattributable to the failed contract to unitholderson or before the next distribution date unless sub-stantially all of the moneys held to cover the pur-chase are reinvested in substitute securities inaccordance with the trust agreement. If yourtrust is a “regulated investment company” for taxpurposes, the sponsor may direct the reinvestmentof security sale proceeds if the sale is the directresult of serious adverse credit factors which, inthe opinion of the supervisor, would make reten-tion of the securities detrimental to the trust. Insuch a case, the sponsor may, but is not obligatedto, direct the reinvestment of sale proceeds in anyother securities that meet the criteria for inclusionin the trust on the trust’s inception date. Thesponsor may also instruct the trustee to takeaction necessary to ensure that a portfolio contin-ues to satisfy the qualifications of a “regulatedinvestment company” for tax purposes. Your

trust will not participate in rights offerings ofclosed-end funds, if any.

We will increase the size of your trust as wesell units. When we create additional units, wewill seek to replicate the existing portfolio to theextent practicable. When your trust buys securi-ties, it may pay brokerage or other acquisitionfees. You could experience a dilution of yourinvestment because of these fees and fluctuationsin security prices between the time we create unitsand the time your trust buys the securities.When your trust buys or sells securities, we maydirect that it place orders with and pay brokeragecommissions to brokers that sell units or are affili-ated with us, your trust or the trustee.

Pursuant to an exemptive order, your trustmay be able to purchase securities from othertrusts that we sponsor when we create additionalunits. Your trust may also be able to sell securi-ties to other trusts that we sponsor to satisfy unitredemption, pay deferred sales charges or expens-es, in connection with periodic tax compliance orin connection with the termination of your trust.The exemption may enable each trust to elimi-nate commission costs on these transactions.The price for those securities will be the closingprice on the sale date on the exchange where thesecurities are principally traded as certified by usto the trustee.

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

We apply these concessions or agency com-missions as a percent of the public offering priceper unit at the time of the transaction. The bro-ker-dealer concession or agency commission is65% of the sales fee for secondary market sales.For transactions involving unitholders of otherunit investment trusts who use their redemptionor termination proceeds to purchase units ofyour trust, the broker-dealer concession oragency commission is 1.30% of the public offer-ing price per unit. No broker-dealer concessionor agency commission is paid to broker-dealers,investment advisers or other selling firms in con-nection with unit sales in Fee Accounts subjectto a Wrap Fee.

Broker-dealers and other firms that sell unitsof certain unit investment trusts for which AAMacts as sponsor are eligible to receive additionalcompensation for volume sales. The sponsoroffers two separate volume concession structuresfor certain trusts that are referred to as “VolumeConcession A” and “Volume Concession B.” Thetrusts offered in this prospectus are VolumeConcession A trusts. Broker-dealers and otherfirms that sell units of any Volume Concession Atrust are eligible to receive the additional compen-sation described below. Such payments will be inaddition to the regular concessions paid to firmsas set forth in the applicable trust’s prospectus.The additional concession is based on total initialoffering period sales of all Volume Concession Atrusts during a calendar quarter as set forth in thefollowing table:

Broker-dealer firms will not receive additionalcompensation unless they sell at least $10.0 mil-lion of units of Volume Concession A trusts dur-ing a calendar quarter. For example, if a firm sells$9.5 million of units of Volume Concession Atrusts in the initial offering period during a calen-dar quarter, the firm will not receive any addi-tional compensation with respect to such trusts.Once a firm reaches a particular breakpoint dur-ing a quarter, the firm will receive the stated vol-ume concession on all initial offering period salesof Volume Concession A trusts during the appli-cable quarter. For example, if a firm sells $12.5million of units of Volume Concession A trusts inthe initial offering period during a calendar quar-ter, the firm will receive additional compensationof 0.05% of $12.5 million and if a firm sells$27.0 million of units of Volume Concession Atrusts in the initial offering period during a calen-dar quarter, the firm will receive additional com-pensation of 0.100% of $27.0 million.

In addition, dealer firms will not receive vol-ume concessions on the sale of units which arenot subject to a transactional sales charge.However, such sales will be included in determin-ing whether a firm has met the sales level break-points for volume concessions subject to the poli-cies of the related selling firm. Secondary marketsales of all unit trusts are excluded for purposes ofthese volume concessions. We will pay theseamounts out of our own assets within a reason-able time following each calendar quarter.

Any sales fee discount is borne by the bro-ker-dealer or selling firm out of the broker-dealerconcession or agency commission. We reservethe right to change the amount of concessions oragency commissions from time to time.

We currently may provide, at our ownexpense and out of our own profits, additional

compensation and benefits to broker-dealers whosell units of your trust and our other products.This compensation is intended to result in addi-tional sales of our products and/or compensatebroker-dealers and financial advisors for past sales.A number of factors are considered in determin-ing whether to pay these additional amounts.Such factors may include, but are not limited to,the level or type of services provided by the inter-mediary, the level or expected level of sales of ourproducts by the intermediary or its agents, theplacing of our products on a preferred or recom-mended product list and access to an intermedi-ary’s personnel. We may make these payments formarketing, promotional or related expenses,including, but not limited to, expenses of enter-taining retail customers and financial advisors,advertising, sponsorship of events or seminars,obtaining information about the breakdown ofunit sales among an intermediary’s representativesor offices, obtaining shelf space in broker-dealerfirms and similar activities designed to promotethe sale of our products. We make such pay-ments to a substantial majority of intermediariesthat sell our products. We may also make certainpayments to, or on behalf of, intermediaries todefray a portion of their costs incurred for thepurpose of facilitating unit sales, such as the costsof developing or purchasing trading systems toprocess unit trades. Payments of such additionalcompensation described in this paragraph and thevolume concessions described above, some ofwhich may be characterized as “revenue sharing,”may create an incentive for financial intermedi-aries and their agents to sell or recommend ourproducts, including your trust, over other prod-ucts. These arrangements will not change theprice you pay for your units.

We generally register units for sale in variousstates in the U.S. We do not register units forsale in any foreign country. This prospectus does

TTAAXXEESS——RREEGGUULLAATTEEDD IINNVVEESSTTMMEENNTT CCOOMMPPAANNIIEESS

This section summarizes some of the mainU.S. federal income tax consequences of owningunits of your trust if your trust intends to qualifyas a “regulated investment company” under feder-al tax laws. The tax structure of your trust is setforth under “Essential Information—TaxStructure” in the “Investment Summary” sectionfor your trust in this prospectus.

This section is current as of the date of thisprospectus. Tax laws and interpretations changefrequently, and these summaries do not describeall of the tax consequences to all taxpayers. Forexample, these summaries generally do notdescribe your situation if you are a corporation, anon-U.S. person, a broker/dealer, or otherinvestor with special circumstances. In addition,this section does not describe your state, local orforeign tax consequences.

This federal income tax summary is based inpart on the advice of counsel to the sponsor. TheInternal Revenue Service could disagree with anyconclusions set forth in this section. In addition,

our counsel was not asked to review, and has notreached a conclusion with respect to the federalincome tax treatment of the assets to be depositedin your trust. This may not be sufficient for youto use for the purpose of avoiding penalties underfederal tax law.

As with any investment, you should seekadvice based on your individual circumstancesfrom your own tax advisor.

TTrruusstt SSttaattuuss.. Your trust intends to qualify asa “regulated investment company” under the fed-eral tax laws. If your trust qualifies as a regulatedinvestment company and distributes its income asrequired by the tax law, your trust generally willnot pay federal income taxes. If your trust investsin a partnership, an adverse federal income taxaudit of that partnership could result in the trustbeing required to pay federal income tax or pay adeficiency dividend (without having receivedadditional cash).

DDiissttrriibbuuttiioonnss.. Trust distributions are general-ly taxable. After the end of each year, you willreceive a tax statement that separates your trust’sdistributions into three categories, ordinaryincome distributions, capital gain dividends andreturn of capital. Ordinary income distributionsare generally taxed at your ordinary tax rate, how-ever, as further discussed below, certain ordinaryincome distributions received from your trustmay be taxed at the capital gains tax rates.Generally, you will treat all capital gain dividendsas long-term capital gains regardless of how longyou have owned your units. To determine youractual tax liability for your capital gain dividends,you must calculate your total net capital gain orloss for the tax year after considering all of yourother taxable transactions, as described below. Inaddition, your trust may make distributions thatrepresent a return of capital for tax purposes and

Page 69: Supplement to the Prospectus - Advisors Asset Management...9 CBRL Cracker Barrel Old Country Store, Inc. 1.01 168.69 1,518 26 PLAY Dave & Buster’s Entertainment, Inc. (4) 1.01 58.19

thus will generally not be taxable to you. Areturn of capital, although not initially taxable toyou, will result in a reduction in the basis in yourunits and subsequently result in higher levels oftaxable capital gains in the future. In addition, ifthe non-dividend distribution exceeds your basisin your units, you will have long-term or short-term gain depending upon your holding period.The tax status of your distributions from yourtrust is not affected by whether you reinvest yourdistributions in additional units or receive themin cash. The income from your trust that youmust take into account for federal income taxpurposes is not reduced by amounts used to pay adeferred sales fee, if any. The tax laws mayrequire you to treat distributions made to you inJanuary as if you had received them on December31 of the previous year. Income from your trustmay also be subject to a 3.8 percent “medicaretax.” This tax generally applies to your net invest-ment income if your adjusted gross incomeexceeds certain threshold amounts, which are$250,000 in the case of married couples filingjoint returns and $200,000 in the case of singleindividuals.

DDiivviiddeennddss RReecceeiivveedd DDeedduuccttiioonn.. A corpora-tion that owns units generally will not be enti-tled to the dividends received deduction withrespect to many dividends received from yourtrust because the dividends received deduction isgenerally not available for distributions fromregulated investment companies. However, cer-tain ordinary income dividends on units that areattributable to qualifying dividends received byyour trust from certain corporations may bereported by the trust as being eligible for thedividends received deduction.

SSaallee oorr RReeddeemmppttiioonn ooff UUnniittss.. If you sell orredeem your units, you will generally recognize ataxable gain or loss. To determine the amount of

this gain or loss, you must subtract your tax basisin your units from the amount you receive in thetransaction. Your tax basis in your units is gener-ally equal to the cost of your units, generallyincluding sales charges. In some cases, however,you may have to adjust your tax basis after youpurchase your units.

CCaappiittaall GGaaiinnss aanndd LLoosssseess aanndd CCeerrttaaiinnOOrrddiinnaarryy IInnccoommee DDiivviiddeennddss.. If you are an indi-vidual, the maximum marginal stated federal taxrate for net capital gain is generally 20% for tax-payers in the 39.6% tax bracket, 15% for taxpay-ers in the 25%, 28%, 33% and 35% tax bracketsand 0% for taxpayers in the 10% and 15% taxbrackets. Some portion of your capital gain divi-dends may be subject to higher maximum mar-ginal stated federal income tax rates. Some por-tion of your capital gain dividends may be attrib-utable to the trust’s interest in a master limitedpartnership which may be subject to a maximummarginal stated federal income tax rate of 28%,rather than the rates set forth above. In addition,capital gain received from assets held for morethan one year that is considered “unrecapturedsection 1250 gain” (which may be the case, forexample, with some capital gains attributable toequity interests in real estate investment truststhat constitute interests in entities treated as realestate investment trusts for federal income taxpurposes) is taxed at a maximum stated tax rateof 25%. In the case of capital gain dividends,the determination of which portion of the capitalgain dividend, if any, is subject to the 28% taxrate or the 25% tax rate, will be made based onrules prescribed by the United States Treasury.Capital gains may also be subject to the“medicare tax” described above.

Net capital gain equals net long-term capitalgain minus net short-term capital loss for the tax-able year. Capital gain or loss is long-term if the

holding period for the asset is more than one yearand is short-term if the holding period for theasset is one year or less. You must exclude thedate you purchase your units to determine yourholding period. However, if you receive a capitalgain dividend from your trust and sell your unitat a loss after holding it for six months or less, theloss will be recharacterized as long-term capitalloss to the extent of the capital gain dividendreceived. The tax rates for capital gains realizedfrom assets held for one year or less are generallythe same as for ordinary income. The InternalRevenue Code treats certain capital gains as ordi-nary income in special situations.

Ordinary income dividends received by anindividual unitholder from a regulated investmentcompany such as your trust are generally taxed atthe same rates that apply to net capital gain (asdiscussed above), provided certain holding periodrequirements are satisfied and provided the divi-dends are attributable to qualifying dividendsreceived by your trust itself. Distributions withrespect to shares in real estate investment trustsare qualifying dividends only in limited circum-stances. Your trust will provide notice to itsunitholders of the amount of any distributionwhich may be taken into account as a dividendwhich is eligible for the capital gains tax rates.

IInn--KKiinndd DDiissttrriibbuuttiioonnss.. Under certain circum-stances, as described in this prospectus, you mayreceive an in-kind distribution of trust securitieswhen you redeem units or when your trust termi-nates. This distribution will be treated as a salefor federal income tax purposes and you will gen-erally recognize gain or loss, generally based onthe value at that time of the securities and theamount of cash received. The Internal RevenueService could however assert that a loss could notbe currently deducted.

RRoolllloovveerrss aanndd EExxcchhaannggeess.. If you elect to haveyour proceeds from your trust rolled over into afuture trust, the exchange would generally be con-sidered a sale for federal income tax purposes.

DDeedduuccttiibbiilliittyy ooff TTrruusstt EExxppeennsseess.. Expensesincurred and deducted by your trust will generallynot be treated as income taxable to you. In somecases, however, you may be required to treat yourportion of these trust expenses as income. Inthese cases you may be able to take a deductionfor these expenses. However, certain miscella-neous itemized deductions, such as investmentexpenses, may be deducted by individuals onlyto the extent that all of these deductions exceed2% of the individual’s adjusted gross income.Some individuals may also be subject to furtherlimitations on the amount of their itemizeddeductions, depending on their income.

FFoorreeiiggnn TTaaxx CCrreeddiitt.. If your trust invests inany foreign securities, the tax statement that youreceive may include an item showing foreign taxesyour trust paid to other countries. In this case,dividends taxed to you will include your share ofthe taxes your trust paid to other countries. Youmay be able to deduct or receive a tax credit foryour share of these taxes.

IInnvveessttmmeennttss iinn CCeerrttaaiinn FFoorreeiiggnn CCoorrppoorraattiioonnss..If your trust holds an equity interest in any “pas-sive foreign investment companies” (“PFICs”),which are generally certain foreign corporationsthat receive at least 75% of their annual grossincome from passive sources (such as interest, div-idends, certain rents and royalties or capitalgains) or that hold at least 50% of their assets ininvestments producing such passive income, thetrust could be subject to U.S. federal income taxand additional interest charges on gains and cer-tain distributions with respect to those equityinterests, even if all the income or gain is timely

distributed to its unitholders. Your trust will notbe able to pass through to its unitholders anycredit or deduction for such taxes. Your trustmay be able to make an election that could ame-liorate these adverse tax consequences. In thiscase, your trust would recognize as ordinaryincome any increase in the value of such PFICshares, and as ordinary loss any decrease in suchvalue to the extent it did not exceed prior increas-es included in income. Under this election, yourtrust might be required to recognize in a yearincome in excess of its distributions from PFICsand its proceeds from dispositions of PFIC stockduring that year, and such income would never-theless be subject to the distribution requirementand would be taken into account for purposes ofthe 4% excise tax. Dividends paid by PFICs arenot treated as qualified dividend income.

FFoorreeiiggnn IInnvveessttoorrss.. If you are a foreign investor(i.e., an investor other than a U.S. citizen or resi-dent or a U.S. corporation, partnership, estate ortrust), you should be aware that, generally, subjectto applicable tax treaties, distributions from yourtrust will be characterized as dividends for federalincome tax purposes (other than dividends whichyour trust properly reports as capital gain divi-dends) and will be subject to U.S. income taxes,including withholding taxes, subject to certainexceptions described below. However, distribu-tions received by a foreign investor from yourtrust that are properly reported by your trust ascapital gain dividends may not be subject to U.S.federal income taxes, including withholding taxes,provided that your trust makes certain electionsand certain other conditions are met.Distributions from your trust that are properlyreported by the trust as an interest-related divi-dend attributable to certain interest incomereceived by the trust or as a short-term capitalgain dividend attributable to certain net short-term capital gain income received by the trust

may not be subject to U.S. federal income taxes,including withholding taxes when received by cer-tain foreign investors, provided that the trustmakes certain elections and certain other condi-tions are met. In addition, distributions inrespect of units may be subject to a U.S. with-holding tax of 30% in the case of distributions to(i) certain non-U.S. financial institutions thathave not entered into an agreement with theU.S. Treasury to collect and disclose certaininformation and are not resident in a jurisdictionthat has entered into such an agreement with theU.S. Treasury and (ii) certain other non-U.S. enti-ties that do not provide certain certifications andinformation about the entity’s U.S. owners.Dispositions of units by such persons may besubject to such withholding after December 31,2018. You should also consult your tax advisorwith respect to other U.S. tax withholding andreporting requirements.

This federal income tax summary is based inpart on the advice and opinion of counsel to thesponsor. The Internal Revenue Service could dis-agree with any conclusions set forth in this sec-tion. In addition, our counsel was not asked toreview, and has not reached a conclusion withrespect to the federal income tax treatment of theassets to be deposited in your trust. This may notbe sufficient for you to use for the purpose ofavoiding penalties under federal tax law.

As with any investment, you should seekadvice based on your individual circumstancesfrom your own tax advisor.

AAsssseettss ooff tthhee TTrruusstt.. Your trust is expected tohold one or more of the following: (i) shares ofstock in corporations (the “Stocks”) that are treat-ed as equity for federal income tax purposes, (ii)equity interests (the “REIT Shares”) in real estateinvestment trusts (“REITs”) that constitute inter-ests in entities treated as real estate investmenttrusts for federal income tax purposes, and (iii)shares (the “RIC Shares”) in funds qualifying asregulated investment companies (“RICs”) that aretreated as interests in regulated investment com-panies for federal income tax purposes.

It is possible that your trust will also holdother assets, including assets that are treated dif-ferently for federal income tax purposes fromthose described above, in which case you willhave federal income tax consequences differentfrom or in addition to those described in this sec-tion. All of the assets held by your trust consti-tute the “Trust Assets.” Neither our counsel norwe have analyzed the proper federal income taxtreatment of the Trust Assets and thus neitherour counsel nor we have reached a conclusionregarding the federal income tax treatment ofthe Trust Assets.

TTrruusstt SSttaattuuss.. The trust is considered a grantortrust under federal income tax laws. In grantortrusts, investors are deemed for federal income taxpurposes, to own the underlying assets of the trustdirectly. All taxability issues are taken intoaccount at the unit owner level. Income passesthrough to unit owners as realized by the trust.

Income is reported gross of expenses.Expenses are separately reported based on a per-centage of distributions. Generally, the cashreceived by unit owners is the net of income andexpenses reported.

The grantor trust structure is a widely heldfixed investment trust (“WHFIT”), and fallsunder what is commonly referred to as theWHFIT regulations.

If your trust is at all times operated in accor-dance with the documents establishing your trustand certain requirements of federal income taxlaw are met, your trust will not be taxed as a cor-poration for federal income tax purposes. As aunit owner, you will be treated as the owner of apro rata portion of each of the Trust Assets, andas such you will be considered to have received apro rata share of income (e.g., dividends and capi-tal gains, if any) from each Trust Asset when suchincome would be considered to be received byyou if you directly owned the Trust Assets. Thisis true even if you elect to have your distributionsreinvested into additional units. In addition, theincome from Trust Assets that you must take intoaccount for federal income tax purposes is notreduced by amounts used to pay sales charges ortrust expenses. Income from the trust may alsobe subject to a 3.8 percent “medicare tax.” Thistax generally applies to your net investmentincome if your adjusted gross income exceeds cer-tain threshold amounts, which are $250,000 inthe case of married couples filing joint returns

and $200,000 in the case of single individuals.Interest that is excluded from gross income,including exempt-interest dividends from anyRIC Shares held by the trust, are generally notincluded in your net investment income for pur-poses of this tax.

YYoouurr TTaaxx BBaassiiss aanndd IInnccoommee oorr LLoossss uuppoonnDDiissppoossiittiioonn.. If your trust disposes of Trust Assets,you will generally recognize gain or loss. If youdispose of your units or redeem your units forcash, you will also generally recognize gain or loss.To determine the amount of this gain or loss, youmust subtract your tax basis in the related TrustAssets from your share of the total amountreceived in the transaction. You can generallydetermine your initial tax basis in each Trust Assetby apportioning the cost of your units, includingsales charges, among the Trust Assets ratablyaccording to their values on the date you acquireyour units. In certain circumstances, however,you may have to adjust your tax basis after youacquire your units (for example, in the case of cer-tain dividends that exceed a corporation’s accu-mulated earnings and profits, or in the case ofcertain distributions with respect to any REITShares that represent a return of capital, as dis-cussed below).

If you are an individual, the maximum mar-ginal stated federal tax rate for net capital gain isgenerally 20% for taxpayers in the 39.6% taxbracket, 15% for taxpayers in the 25%, 28%,33% and 35% tax brackets and 0% for taxpayersin the 10% and 15% tax brackets. Note thatsome portion of any capital gain dividends youreceive might be attributable to a RIC’s interest ina master limited partnership which may be sub-ject to a maximum marginal stated federal incometax rate of 28%, rather than the rates set forthabove. In addition, capital gain received fromassets held for more than one year that is consid-

ered “unrecaptured section 1250 gain” (whichmay be the case, for example, with some capitalgains attributable to equity interests in real estateinvestment trusts that constitute interests in enti-ties treated as real estate investment trusts for fed-eral income tax purposes) is taxed at a maximumstated tax rate of 25%. In the case of capital gaindividends, the determination of which portion ofthe capital gain dividend, if any, is subject to the28% tax rate or the 25% tax rate, will be madebased on rules prescribed by the United StatesTreasury. Capital gains may also be subject to the“medicare tax” described above.

Net capital gain equals net long-term capitalgain minus net short-term capital loss for the tax-able year. Capital gain or loss is long-term if theholding period for the asset is more than one yearand is short-term if the holding period for theasset is one year or less. You must exclude the dateyou purchase your units to determine your hold-ing period. The tax rates for capital gains realizedfrom assets held for one year or less are generallythe same as for ordinary income. The InternalRevenue Code, however, treats certain capitalgains as ordinary income in special situations.

DDiivviiddeennddss ffrroomm SSttoocckkss.. Certain dividendsreceived with respect to the Stocks held by thetrust, if any, may qualify to be taxed at the samerates that apply to net capital gain (as discussedabove), provided certain holding period require-ments are satisfied.

DDiivviiddeennddss ffrroomm RRIICC SShhaarreess aanndd RREEIITT SShhaarreess..Some dividends on REIT Shares or RIC Shares, ifany, held by the trust, may be reported by theREIT or RIC as “capital gain dividends,” general-ly taxable to you as long-term capital gains. Somedividends on RIC Shares may qualify as “exempt-interest dividends,” which generally are excludedfrom your gross income for federal income tax

purposes. Some or all of the exempt-interest divi-dends, however may be taken into account indetermining your alternative minimum tax, andmay have other tax consequences (e.g., they mayaffect the amount of your social security benefitsthat are taxed). Other dividends on the REITShares or the RIC Shares will generally be taxableto you as ordinary income. Certain ordinaryincome dividends from a RIC may qualify to betaxed at the same rates that apply to net capitalgain (as discussed above), provided certain hold-ing period requirements are satisfied and providedthe dividends are attributable to qualifying divi-dends received by the RIC itself. Regulatedinvestment companies are required to providenotice to their shareholders of the amount of anydistribution that may be taken into account as adividend that is eligible for the capital gains taxrates. In limited circumstances, some of the ordi-nary income dividends from a REIT may alsoqualify to be taxed at the same rates that apply tonet capital gains. If you hold a unit for sixmonths or less or if your trust holds a RIC Shareor REIT Share for six months or less, any lossincurred by you related to the disposition of suchRIC Share or REIT Share will be disallowed tothe extent of the exempt-interest dividends youreceived. To the extent, if any, it is not disal-lowed, it will be treated as a long-term capital lossto the extent of any long-term capital gain distri-butions received (or deemed to have beenreceived) with respect to such RIC Share or REITShare. Distributions of income or capital gainsdeclared on the REIT Shares or the RIC Shares inOctober, November or December will be deemedto have been paid to you on December 31 of theyear they are declared, even when paid by theREIT or the RIC during the following January.

DDiivviiddeennddss RReecceeiivveedd DDeedduuccttiioonn.. Generally, adomestic corporation owning units in a trustmay be eligible for the dividends received deduc-

tion with respect to such unit owner’s pro rataportion of certain types of dividends received bythe trust. However, a corporation generally willnot be entitled to the dividends received deduc-tion with respect to dividends from most foreigncorporations or from REITs or RICs. However,certain dividends on RIC Shares that are attribut-able to dividends received by the RIC itself fromcertain domestic corporations may be reported bythe RIC as being eligible for the dividendsreceived deduction.

Under certain circum-stances as described in this prospectus, you mayrequest an In-Kind Distribution of Trust Assetswhen you redeem your units or at your trust’s ter-mination.

You will not recognize gain or lossif you only receive whole Trust Assets in exchangefor the identical amount of your pro rata portionof the same Trust Assets held by your trust.However, if you also receive cash in exchange fora Trust Asset or a fractional portion of a TrustAsset, you will generally recognize gain or lossbased on the difference between the amount ofcash you receive and your tax basis in such TrustAsset or fractional portion.

Generally, for federal income tax pur-poses, you must take into account your full prorata share of your trust’s income, even if some ofthat income is used to pay trust expenses. Youmay deduct your pro rata share of each expensepaid by your trust to the same extent as if youdirectly paid the expense. You may be required totreat some or all of the expenses of your trust asmiscellaneous itemized deductions. Individualsmay only deduct certain miscellaneous itemizeddeductions to the extent they exceed 2% ofadjusted gross income. Some individuals mayalso be subject to further limitations on theamount of their itemized deductions, dependingon their income.

If any of the RICs pay exempt-interest divi-dends, which are treated as tax-exempt interest forfederal income tax purposes, you will not be ableto deduct some of your share of the trust expens-es. In addition, you will not be able to deductsome of your interest expense for debt that youincur or continue to purchase or carry your units.

FFoorreeiiggnn IInnvveessttoorrss,, TTaaxxeess aanndd IInnvveessttmmeennttss..Distributions by your trust that are treated asU.S. source income (e.g., dividends received onStocks of domestic corporations) will generallybe subject to U.S. income taxation and with-holding in the case of units held by nonresidentalien individuals, foreign corporations or othernon- U.S. persons, subject to any applicabletreaty. If you are a foreign investor (i.e., aninvestor other than a U.S. citizen or resident or aU.S. corporation, partnership, estate or trust),you may not be subject to U.S. federal incometaxes, including withholding taxes, on some orall of the income from your trust or on any gainfrom the sale or redemption of your units, pro-vided that certain conditions are met. Youshould consult your tax advisor with respect to

the conditions you must meet in order to beexempt for U.S. tax purposes. Distributions inrespect of units may be subject to a U.S. with-holding tax of 30% in the case of distributionsto (i) certain non-U.S. financial institutions thathave not entered into an agreement with theU.S. Treasury to collect and disclose certaininformation and are not resident in a jurisdic-tion that has entered into such an agreementwith the U.S. Treasury and (ii) certain othernon- U.S. entities that do not provide certaincertifications and information about the entity’sU.S. owners. Dispositions of units by such per-sons may be subject to such withholding afterDecember 31, 2018. You should also consultyour tax advisor with respect to other U.S. taxwithholding and reporting requirements.

Some distributions by your trust may be sub-ject to foreign withholding taxes. Any incomewithheld will still be treated as income to you.Under the grantor trust rules, you are consideredto have paid directly your share of any foreigntaxes that are paid. Therefore, for U.S. tax pur-poses, you may be entitled to a foreign tax creditor deduction for those foreign taxes.

Under certain circumstances, a RIC may electto pass through to its shareholders certain foreigntaxes paid by the RIC. If a RIC makes this elec-tion with respect to RIC Shares, you must includein your income for federal income tax purposesyour portion of such taxes and you may be enti-tled to a credit or deduction for such taxes.

If any U.S. investor is treated as owningdirectly or indirectly 10 percent or more of thecombined voting power of the stock of a foreigncorporation, and all U.S. shareholders of thatcorporation collectively own more than 50 per-cent of the vote or value of the stock of that cor-poration, the foreign corporation may be treated

Ifyou own 10 percent or more of a CFC (throughyour trust and in combination with your otherinvestments) or possibly if your trust owns 10percent or more of a CFC, you will be requiredto include certain types of the CFC’s income inyour taxable income for federal income tax pur-poses whether or not such income is distributedto your trust or to you.

A foreign corporation will generally be treatedas a passive foreign investment company (“PFIC”)if 75 percent or more of its income is passiveincome or if 50 percent or more of its assets areheld to produce passive income. If your trustpurchases shares in a PFIC, you may be subject toU.S. federal income tax on a portion of certaindistributions or on gains from the disposition ofsuch shares at rates that were applicable in prioryears and any gain may be recharacterized as ordi-nary income that is not eligible for the lower netcapital gains tax rate. Additional charges in thenature of interest may also be imposed on you.Certain elections may be available with respect toPFICs that would limit these consequences.However, these elections would require you toinclude certain income of the PFIC in your tax-able income even if not distributed to the trust orto you, or require you to annually recognize asordinary income any increase in the value of theshares of the PFIC, thus requiring you to recog-nize income for federal income tax purposes inexcess of your actual distributions from PFICsand proceeds from dispositions of PFIC stockduring a particular year. Dividends paid byPFICs are not eligible to be taxed at the net capi-tal gains tax rate.
