(1)

As of the Evaluation Time (defined below in footnote 4) on\nthe Initial Date of Deposit, we may adjust the number of Units of the Trust so that the Public Offering Price per Unit will equal approximately\n$10.00. If we make such an adjustment, the fractional undivided interest per Unit will vary from the amount indicated above.

(2)

The Public Offering Price shown above reflects the value of the Securities on the business day prior to\nthe Initial Date of Deposit. No investor will purchase Units at this price. The price you pay for your Units will be based on their valuation\nat the Evaluation Time on the date you purchase your Units. On the Initial Date of Deposit, the Public Offering Price per Unit will not\ninclude any accumulated dividends on the Securities. After this date, a pro rata share of any accumulated dividends on the Securities\nwill be included.

(3)

You will pay a maximum sales charge of 1.85% of the Public Offering Price per Unit (equivalent to 1.85%\nof the net amount invested) which consists of an initial sales charge, a deferred sales charge and a creation and development fee. The\nsales charges are described in the “Fee Table.”

(4)

Each listed Security is valued at its last closing sale price at the Evaluation Time on the business day\nprior to the Initial Date of Deposit. If a Security is not listed, or if no closing sale price exists, it is valued at its closing ask\nprice on such date. See “Public Offering—The Value of the Securities.” Evaluations for purposes of determining the purchase,\nsale or redemption price of Units are made as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00\np.m. Eastern time) on each day on which it is open (the “Evaluation Time”).

(5)

The creation and development fee and the estimated organization costs per Unit will be deducted from the\nassets of the Trust at the end of the initial offering period. If Units are redeemed prior to the close of the initial offering period,\nthese fees will not be deducted from the redemption proceeds. See “Redeeming Your Units.”

(6)

See “Amending or Terminating the Indenture.”

(7)

The Trustee will distribute money from the Income Account, as determined at the semi-annual Income Account\nDistribution Record Date, semi-annually on the twenty-fifth day of each June and December to Unit holders of record on the tenth day of\nsuch months provided the amount in the Income Account equals at least $1.00 per 100 Units. The Trustee will make distributions from the\nCapital Account monthly on the twenty-fifth day of each month to Unit holders of record on the tenth day of such month provided the amount\navailable for distribution from the Capital Account equals at least $1.00 per 100 Units. See “Income and Capital Distributions.”

Fee Table (Unaudited)

Fee Table

This Fee Table describes\nthe fees and expenses that you may, directly or indirectly, pay if you buy and hold Units of the Trust. See “Public Offering”\nand “Expenses and Charges.” Although the Trust has a term of approximately 15 months and is a unit investment trust rather\nthan a mutual fund, this information allows you to compare fees.

Example

This example is intended\nto help you compare the cost of investing in the Trust with the cost of investing in other investment products. The example assumes that\nyou invest $10,000 in the Trust and the principal amount and distributions are rolled every 15 months into a New Trust. The example\nalso assumes a 5% return on your investment each year and that your Trust’s, and each New Trust’s, sales charges and expenses\nstay the same. The example does not take into consideration transaction fees which may be charged by certain broker/dealers for processing\nredemption requests. Although your actual costs may vary, based on these assumptions your costs, assuming you roll your proceeds from\none trust to the next for the periods shown, would be:

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

1 Year	3 Years	5 Years	10 Years
$273	$837	$1,153	$2,474

If you elect not to roll\nyour proceeds from one trust to the next, your costs will be limited by the number of years your proceeds are invested, as set forth above.\n

(a)

The combination of the initial and deferred sales charge comprises what we refer to as the “transactional\nsales charge.” The initial sales charge is actually equal to the difference between the maximum sales charge of 1.85% and the sum\nof any remaining deferred sales charge and creation and development fee. When the Public Offering Price per Unit equals $10, there is\nno initial sales charge. If the price you pay for your Units exceeds $10 per Unit, you will pay an initial sales charge.

(b)

The deferred sales charge is a fixed dollar amount equal to $.135 per Unit which, as a percentage of the\nPublic Offering Price, will vary over time. The deferred sales charge will be deducted in three monthly installments commencing February\n19, 2027.

(c)

The creation and development fee compensates the Sponsor for creating and developing the Trust. The creation\nand development fee is a charge of $.050 per Unit collected at the end of the initial offering period, which is expected to be approximately\nthree months from the Initial Date of Deposit. If the price you pay for your Units exceeds $10 per Unit, the creation and development\nfee will be less than 0.50%; if the price you pay for your Units is less than $10 per Unit, the creation and development fee will exceed\n0.50%. If you purchase Units after the initial offering period, you will not be assessed the creation and development fee.

(d)

Estimated organization costs, which include a one-time licensing fee, will be deducted from the assets\nof the Trust at the end of the initial offering period. Estimated organization costs are assessed on a fixed dollar amount per Unit basis\nwhich, as a percentage of average net assets, will vary over time.

(e)

Each of the fees listed herein is assessed on a fixed dollar amount per Unit basis which, as a percentage\nof average net assets, will vary over time.

(f)

Other operating expenses do not include brokerage costs and other portfolio transaction fees. In certain\ncircumstances the Trust may incur additional expenses not set forth above. See “Expenses and Charges.”

Report of Independent Registered Public Accounting\n Firm

To\nthe Unit Holders and the Sponsor, First Trust Portfolios L.P., of FT 13311

Opinion\non the Statement of Net Assets

We have audited the\naccompanying statement of net assets, including the schedule of investments, of FT 13311, comprising American\nHeroes Portfolio, Series 6 (the “Trust”), one of the series constituting the FT Series, as of the opening of business\non November 2, 2026 (Initial Date of Deposit), and the related notes. In our opinion, the statement of net assets presents fairly, in\nall material respects, the financial position of the Trust as of the opening of business on November 2, 2026 (Initial Date of Deposit),\nin conformity with accounting principles generally accepted in the United States of America.

Basis\nfor Opinion

This statement of net\nassets is the responsibility of the Trust’s Sponsor. Our responsibility is to express an opinion on this statement of net assets\nbased on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB)\nand are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules\nand regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit\nin accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance\nabout whether the statement of net assets is free of material misstatement, whether due to error or fraud. The Trust is not required to\nhave, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required\nto obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness\nof the Trust’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included\nperforming procedures to assess the risks of material misstatement of the statement of net assets, whether due to error or fraud, and\nperforming procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts\nand disclosures in the statement of net assets. Our audit also included evaluating the accounting principles used and significant estimates\nmade by the Trust’s Sponsor, as well as evaluating the overall presentation of the statement of net assets. Our procedures included\nconfirmation of the irrevocable letter of credit held by The Bank of New York Mellon, the Trustee, and deposited in the Trust for the\npurchase of securities, as shown in the statement of net assets, as of the opening of business on November 2, 2026, by correspondence\nwith the Trustee. We believe that our audit provides a reasonable basis for our opinion.

NOTES\nTO STATEMENT OF NET ASSETS

The Trust is registered as a unit investment\ntrust under the Investment Company Act of 1940. The Sponsor is responsible for the preparation of financial statements in accordance with\naccounting principles generally accepted in the United States which require the Sponsor to make estimates and assumptions that affect\namounts reported herein. Actual results could differ from those estimates. The Trust intends to comply in its initial fiscal year and\nthereafter with provisions of the Internal Revenue Code applicable to regulated investment companies and as such, will not be subject\nto federal income taxes on otherwise taxable income (including net realized capital gains) distributed to Unit holders.

(1)

The Trust invests in a diversified portfolio of common stocks. Aggregate\ncost of the Securities listed under “Schedule of Investments” is based on their aggregate underlying value. The Trust has\na Mandatory Termination Date of February 14, 2028.

(2)

An irrevocable letter of credit issued by The Bank of New York Mellon,\nof which approximately $300,000 has been allocated to the Trust, has been deposited with the Trustee as collateral, covering the monies\nnecessary for the purchase of the Securities according to their purchase contracts.

(3)

A portion of the Public Offering Price consists of an amount sufficient\nto reimburse the Sponsor for all or a portion of the costs of establishing the Trust. These costs have been estimated at $.0660 per Unit.\nA payment will be made at the end of the initial offering period to an account maintained by the Trustee from which the obligation of\nthe investors to the Sponsor will be satisfied. To the extent that actual organization costs of the Trust are greater than the estimated\namount, only the estimated organization costs added to the Public Offering Price will be reimbursed to the Sponsor and deducted from the\nassets of the Trust.

(4)

Represents the amount of mandatory deferred sales charge distributions\nof $.135 per Unit, payable to the Sponsor in three equal monthly installments beginning on February 19, 2027 and on the twentieth day\nof each month thereafter (or if such date is not a business day, on the preceding business day) through April 20, 2027. If Unit holders\nredeem Units before April 20, 2027, they will have to pay the remaining amount of the deferred sales charge applicable to such Units when\nthey redeem them.

(5)

The creation and development fee ($.050 per Unit) is payable by the Trust\non behalf of Unit holders out of assets of the Trust at the end of the initial offering period. If Units are redeemed prior to the close\nof the initial offering period, the fee will not be deducted from the proceeds.

(6)

Net asset value per Unit is calculated by dividing the Trust’s net\nassets by the number of Units outstanding. This figure includes organization costs and the creation and development fee, which will only\nbe assessed to Units outstanding at the end of the initial offering period.

(7)

The aggregate cost to investors in the Trust includes a maximum sales charge\n(comprised of an initial and a deferred sales charge and the creation and development fee) computed at the rate of 1.85% of the Public\nOffering Price (equivalent to 1.85% of the net amount invested, exclusive of the deferred sales charge and the creation and development\nfee), assuming no reduction of the maximum sales charge as set forth under “Public Offering.”

(1)

All Securities are represented by regular way contracts to purchase such\nSecurities which are backed by an irrevocable letter of credit deposited with the Trustee. The Sponsor entered into purchase contracts\nfor the Securities on November 2, 2026. Such purchase contracts are expected to settle within one business day.

(2)

The cost of the Securities to the Trust represents the aggregate underlying\nvalue with respect to the Securities acquired (generally determined by the closing sale prices of the listed Securities and the ask prices\nof over-the-counter traded Securities at the Evaluation Time on the business day prior to the Initial Date of Deposit). The\ncost of Securities to the Trust may not compute due to rounding the market value per share. The valuation of the Securities has\nbeen determined by the Sponsor. In accordance with Financial Accounting Standards Board Accounting Standards Codification 820, “Fair\nValue Measurement,” the Trust’s investments are classified as Level 1, which refers to securities traded in an active market.\nThe cost of the Securities to the Sponsor and the Sponsor’s loss (which is the difference between the cost of the Securities\nto the Sponsor and the cost of the Securities to the Trust) are $180,250 and $1,278, respectively.

(3)

Common stocks of companies headquartered or incorporated outside the United\nStates comprise approximately 3.31% of the investments of the Trust (consisting of Ireland, 3.31%).

†

This Security represents the common stock of a foreign company which trades on the over-the-counter market\nor on a U.S. national securities exchange.

This Security represents a non-income producing security.

The FT Series

The FT Series Defined.

We,\nFirst Trust Portfolios L.P. (the “Sponsor”), have created hundreds of similar yet separate series of a unit investment trust\nwhich we have named the FT Series. The series to which this prospectus relates, FT 13311, consists of a single portfolio known as\nAmerican Heroes Portfolio, Series 6.

The\nTrust was created under the laws of the State of New York by a Trust Agreement (the “Indenture”) dated the Initial Date of\nDeposit. This agreement, entered into among First Trust Portfolios L.P., as Sponsor, The Bank of New York Mellon as Trustee and First\nTrust Advisors L.P. as Portfolio Supervisor, governs the operation of the Trust.

You may get more specific details concerning the nature, structure\nand risks of this product in an “Information Supplement” by calling the Sponsor at 800–621–1675, dept. code 2.

How We Created the Trust.

On\nthe Initial Date of Deposit, we deposited a portfolio of common stocks with the Trustee and, in turn, the Trustee delivered documents\nto us representing our ownership of the Trust in the form of units (“Units”).

After\nthe Initial Date of Deposit, we may deposit additional Securities in the Trust, or cash (including a letter of credit or the equivalent)\nwith instructions to buy more Securities, to create new Units for sale. If we create additional Units, we will attempt, to the extent\npracticable, to maintain the percentage relationship established among the Securities on the Initial Date of Deposit (as set forth in\n“Schedule of Investments”), adjusted to reflect the sale, redemption or liquidation of any of the Securities or any stock\nsplit or a merger or other similar event affecting the issuer of the Securities.

Since\nthe prices of the Securities will fluctuate daily, the ratio of Securities in the Trust, on a market value basis, will also change daily.\nThe portion of Securities represented by each Unit will not change as a result of the deposit of additional Securities or cash in the\nTrust. If we deposit cash, you and new investors may experience a dilution of your investment. This is because prices of Securities will\nfluctuate between the time of the cash deposit and the purchase of the Securities, and because the Trust pays the associated brokerage\nfees. To reduce this dilution, the Trust will try to buy the Securities as close to the Evaluation Time and as close to the evaluation\nprice as possible. In addition, because the Trust pays the brokerage fees associated with the creation of new Units and with the sale\nof Securities to meet redemption and exchange requests, frequent redemption and exchange activity will likely result in higher brokerage\nexpenses.

An\naffiliate of the Trustee may receive these brokerage fees or the Trustee may retain and pay us (or our affiliate) to act as agent for\nthe Trust to buy Securities. If we or an affiliate of ours act as agent to the Trust, we will be subject to the restrictions under the\nInvestment Company Act of 1940, as amended (the “1940 Act”). When acting in an agency capacity, we may select various broker/dealers\nto execute securities transactions on behalf of the Trust, which may include broker/dealers who sell Units of the Trust. We do not consider\nsales of Units of the Trust or any other products sponsored by First Trust as a factor in selecting such broker/dealers.

We\ncannot guarantee that the Trust will keep its present size and composition for any length of time. Securities may be periodically sold\nunder certain circumstances to satisfy Trust obligations, to meet redemption requests and, as described in “Removing Securities\nfrom the Trust,” to maintain the sound investment character of the Trust, and the proceeds received by the Trust will be used to\nmeet Trust obligations or distributed to Unit holders. However, Securities will not be sold to take advantage of market fluctuations or\nchanges in anticipated rates of appreciation or depreciation, or if they no longer meet the criteria by which they were selected. You\nwill not be able to dispose of or vote any of the Securities in the Trust. As the holder of the Securities, the Trustee will vote the\nSecurities and, except as described in “Removing Securities from the Trust,” will endeavor to vote the Securities such that\nthe Securities are voted as closely as possible in the same manner and the same general proportion as are the Securities held by owners\nother than such Trust.

Neither\nwe nor the Trustee will be liable for a failure in any of the Securities. However, if a contract for the purchase of any of the Securities\ninitially deposited in the Trust fails, unless we can purchase substitute Securities (“Replacement Securities”) we will refund\nto you that portion of the purchase price and transactional sales charge resulting from the failed contract on the next Income Account\nDistribution Date. Any Replacement Security the Trust acquires will be identical to those from the failed contract.

Portfolio

Objective.

This unit investment trust seeks above-average\ncapital appreciation. Under normal circumstances, the Trust will invest at least 80% of its assets in U.S. companies.

Portfolio Selection Process.

The\nTrust’s portfolio consists of companies selected from the Veterans Select Index^SM, which measures the performance of\npublicly traded companies that support U.S. military veterans through employment.

To\nbe included in the Veterans Select Index^SM, a company must:

•

Be a member of the VETS eligible universe of companies. The eligible universe is maintained\nby VETS Indexes LLC and includes companies populated from a variety of sources, including annual rankings, survey and recognition programs\nconsidered representative by the VETS Index Committee. The VETS Indexes eligible universe leverages various selection criteria, such as\ncompany culture, policies and reservist accommodations to identify companies most supportive of military veterans, service members and\ntheir families through the creation of employment opportunities and development of employment policies;

•

Have liquidity greater than $40 million in average daily traded dollar volume;

•

Be publicly traded with a market capitalization of at least $1 billion; and

•

Pass the VETS Index Committee credibility review.

As\nof October 26, 2026, the Index consisted of 99 companies.

The\nselection process begins by examining the historical financial results of the stocks from the initial universe of the Veterans Select\nIndex^SM. The stocks are then evaluated by a team of equity analysts using several factors to provide a current comparison of\nthe stocks to each other. These factors include fundamental factors such as sales, earnings and cash flow growth; valuation factors such\nas price to earnings; price to cash flow; price to sales and price to book; technical factors such as price momentum and earnings surprises;\nand qualitative factors such as competitive advantages, new products and quality of management.

The\nequity analysts also consider how the stocks will perform in the future by calculating an estimated value for each of the companies utilizing\na Cash Flow Return on Investment (“CFROI”) method. The CFROI method compares an estimate of a company’s internal rate\nof return against an estimate of a company’s cost of capital. Companies that generate returns in excess of their capital costs are\nfavored over companies that do not. A secondary valuation is also made employing a concept called Economic Margin (“EM”).\nEM measures the return a company earns versus its cost of capital to determine if a company is generating wealth. The analysts use the\nestimated valuations calculated by the CFROI and EM methods to determine which companies are trading at an attractive market price relative\nto their estimated value. These companies are favored for inclusion in the Trust over companies that do not.

After\nconsidering the above factors together, the equity analysts make a final determination and select the stocks with the best prospects to\nmeet the investment objective, that trade at attractive valuations, and, in the opinion of the analysts, are likely to exceed market expectations\nof future cash flows.

The\nfinal portfolio is comprised of 30 approximately equally weighted stocks.

While not\na part of the Trust’s portfolio selection process, the Trust also invests in dividend-paying securities, foreign securities and\ncompanies with various market capitalizations.

As with\nany similar investments, there can be no assurance that the objective of the Trust will be achieved. See “Risk Factors” for\na discussion of the risks of investing in the Trust.

\n \n \n

Risk Factors

Price Volatility. The Trust invests\nin common stocks. The value of the Trust’s Units will fluctuate with changes in the value of these common stocks. Common stock prices\nfluctuate for several reasons including changes in investors’ perceptions of the financial condition of an issuer or the general\ncondition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In\naddition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs\nincrease, negatively impacting issuers.

Because\nthe Trust is not managed, the Trustee will not sell stocks in response to or in anticipation of market fluctuations, as is common in managed\ninvestments. As with any investment, we cannot guarantee that the performance of the Trust will be positive over any period of time, especially\nthe relatively short 15-month life of the Trust, or that you will not lose money. Units of the Trust are not deposits of any bank and\nare not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market\nRisk. Market risk is the risk that a particular security, or Units of the Trust in general, may fall in value or underperform other\ninvestments. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments,\nchanges in interest rates and perceived trends in securities prices. As a means to fight inflation, the Federal Reserve and certain foreign\ncentral banks have raised interest rates and may continue to do so. Potential future bank failures could result in disruption to the broader\nbanking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten\nmarket volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including declining valuations and\nelevated vacancies, could have a broader impact on financial markets. In addition, local, regional or global events such as war, acts\nof terrorism, natural disasters, spread of infectious diseases or other public health issues, recessions, political turbulence or other\nevents could have a significant negative impact on the Trust and its investments. The ongoing adversarial political climate in the United\nStates, as well as political and diplomatic events both domestic and abroad, have had and may continue to have an adverse impact on the\nU.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Trust’s investments and operations.\nThe upcoming elections in the United States may result in significant impacts to international trade relations, tax and immigration policies,\nand other aspects of the national and international political and financial landscape, which could affect, among other things, inflation\nand the securities markets generally. Administrative actions against companies in certain industries, such as the defense industry, prohibiting\nthem from paying dividends or engaging in stock buybacks, may negatively impact the performance of such companies and the Trust’s\ninvestments. Ongoing armed conflicts between Russia and Ukraine in Europe and among the United States, Israel, Iran, Hamas, Hezbollah\nand other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within\nthe markets in Russia, Europe, the Middle East, the United States, and other nations. Such events may also disrupt global trade and supply\nchains, increase sanctions and other governmental actions, and contribute to volatility in oil and natural gas markets. The hostilities\nand sanctions resulting from those hostilities could have a significant impact on certain Trust investments as well as Trust performance.\nThe economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by\ntrade disputes, including the imposition of tariffs, and other matters. A public health crisis, and the ensuing policies enacted by governments\nand central banks in response, could cause significant volatility and uncertainty in global financial markets, negatively impacting global\ngrowth prospects. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others.\nAdvancements in technology may also adversely impact markets and the overall performance of the Trust. For instance, the economy may be\nsignificantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cybersecurity breaches\nof both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including\nthe Trust, to operate properly. Such events could adversely affect the prices and liquidity of the Trust’s portfolio securities\nand could result in disruptions in the trading markets. Any such circumstances could have a materially negative impact on the value of\nthe Trust’s Units and result in increased market volatility.

Dividends. Common stocks may pay\ndividends, but there is no guarantee that the issuers of the common stocks will declare dividends in the future or that, if declared,\nthey will either remain at current levels or increase over time.

Growth\nInvesting Risk. Common stocks with growth characteristics are expected to experience greater earnings growth rates relative to other\ncompanies in the same industry or the economy as a whole based upon their higher than average price to book ratios. Securities of growth\ncompanies may be more volatile than other stocks. If the perception of a company’s growth potential is not realized, the securities\npurchased may not perform as expected, reducing the Trust’s return. In addition, because different types of stocks tend to shift\nin and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as\na whole and other types of securities.

Value\nInvesting Risk. Common stocks with value characteristics are believed to be undervalued or inexpensive relative to other companies\nin the same industry or the economy as a whole based upon their lower than average price to book ratios. These common stocks were generally\nselected on the basis of an issuer’s business and economic fundamentals or the securities’ current and projected credit profiles,\nrelative to current market price. Such securities are subject to the risk of misestimating certain fundamental factors and will generally\nunderperform during periods when value style investments are “out of favor.”

Foreign\nSecurities. Risks of foreign securities include higher brokerage costs; different accounting standards; expropriation, nationalization\nor other adverse political or economic developments; currency devaluations, blockages or transfer restrictions; restrictions on foreign\ninvestments and exchange of securities; inadequate financial information; lack of liquidity of certain foreign markets; and less government\nsupervision and regulation of exchanges, brokers, and issuers in foreign countries. Certain foreign markets have experienced heightened\nvolatility due to recent negative political or economic developments or natural disasters. Securities issued by non-U.S. issuers may pay\ndividends in foreign currencies and may be principally traded in foreign currencies. Therefore, there is a risk that the U.S. dollar value\nof these dividend payments and/or securities will vary with fluctuations in foreign exchange rates.

Small\nand/or Mid Capitalization Companies. Investing in stocks of small and/or mid capitalization companies may involve greater risk than\ninvesting in larger companies. For example, such companies may have limited product lines, as well as shorter operating histories, less\nexperienced management and more limited financial resources than larger companies. Securities of such companies generally trade in lower\nvolumes and are generally subject to greater and less predictable changes in price than securities of larger companies. In addition, small\nand mid-cap stocks may not be widely followed by the investment community, which may result in low demand.

Large Capitalization Companies.\nThe return on investment in stocks of large capitalization companies may be less than the return\non investment in stocks of small and/or mid capitalization companies. Large capitalization companies may also grow at a slower rate than\nthe overall market.

Cybersecurity Risk. As\nthe use of Internet technology has become more prevalent in the course of business, the Trust has become more susceptible to potential\noperational, information security and related risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional\nand unintentional events that may cause the Trust to lose proprietary information, suffer data corruption or lose operational capacity,\nany of which could result in a material adverse effect on the Trust or its Unit holders. Such events could cause the Sponsor of the Trust\nto incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss.\nCybersecurity breaches may involve unauthorized access to digital information systems utilized by the Trust through “hacking”\nor malicious software coding, but may also result from outside attacks such as denial-of service attacks through efforts to make network\nservices unavailable to intended users. Emerging threats like ransomware or zero-day exploits could also cause disruptions to Trust operations.\nIn addition, cybersecurity breaches of the Trust’s third-party service providers, or issuers in which the Trust invests, can also\nsubject the Trust to many of the same risks associated with direct cybersecurity breaches. Further, errors, misconduct, or compromise\nof accounts of employees of the Sponsor, Portfolio Supervisor or the Trust’s third-party service providers can also create material\ncybersecurity risks. The Sponsor of, and third-party service provider to, the Trust have established risk management systems designed\nto reduce the risks associated with cybersecurity. However, there is no guarantee that such efforts will succeed, especially because the\nTrust does not directly control the cybersecurity systems of issuers or third-party service providers. Cybersecurity incidents may also\ntrigger Trust obligations under data privacy laws, potentially increasing notification and compliance burdens. Cybersecurity incidents\naffecting issuers in whose securities the Trust invests may also have a negative impact on the value of the securities of such issuers,\nand in turn, the value of the Trust.

Operational\nRisk. The Trust is subject to risks arising from various operational factors, including, but not limited to, human error, processing\nand communication errors, errors of the Trust’s service providers, counterparties or other third-parties, failed or inadequate processes\nand technology or systems failures. These errors or failures may adversely affect the Trust’s operations, including its ability\nto execute its investment process, calculate or disseminate its NAV in a timely manner, and process purchases or redemptions. The\nTrust relies on third-parties for a range of services. Any delay or failure relating to engaging or maintaining such service providers\nmay affect the Trust’s ability to meet its investment objective. Although the Trust seeks to reduce these operational risks through\ncontrols and procedures, there is no way to completely protect against such risks.

Legislation/Litigation. From time\nto time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain of the\ncompanies represented in the Trust. In addition, litigation regarding any of the issuers of the Securities, or the industries represented\nby these issuers, may negatively impact the value of these Securities. We cannot predict what impact any pending or proposed legislation\nor pending or threatened litigation will have on the value of the Securities.

\n \n \n

Public Offering

The Public Offering Price.

Units will be purchased at the Public Offering\nPrice, the price per Unit of which is comprised of the following:

•

The aggregate underlying value of the Securities;

•

The amount of any cash in the Income and Capital Accounts;

•

Dividends receivable on Securities; and

•

The maximum sales charge (which combines an initial upfront sales charge, a deferred sales charge and the creation and development\nfee).

The price you pay for your Units will differ\nfrom the amount stated under “Summary of Essential Information” due to various factors, including fluctuations in the prices\nof the Securities and changes in the value of the Income and/or Capital Accounts.

Although you are not required to pay for\nyour Units until one business day following your order (the “date of settlement”), you may pay before then. You will become\nthe owner of Units (“Record Owner”) on the date of settlement if payment has been received. If you pay for your Units before\nthe date of settlement, we may use your payment during this time and it may be considered a benefit to us, subject to the limitations\nof the Securities Exchange Act of 1934, as amended.

Organization Costs. Securities purchased\nwith the portion of the Public Offering Price intended to be used to reimburse the Sponsor for the Trust’s organization costs (including\ncosts of preparing the registration statement, the Indenture and other closing documents, registering Units with the SEC and states, licensing\nfees required for the establishment of the Trust under license agreements which provide for full payment of the licensing fee not later\nthan the conclusion of the organization expense period, the initial audit of the Trust’s statement of net assets, legal fees and\nthe initial fees and expenses of the Trustee) will be purchased in the same proportionate relationship as all the Securities contained\nin the Trust. Securities will be sold to reimburse the Sponsor for the Trust’s organization costs at the end of the initial offering\nperiod (a significantly shorter time period than the life of the Trust). During the initial offering period, there may be a decrease in\nthe value of the Securities. To the extent the proceeds from the sale of these Securities are insufficient to repay the Sponsor for Trust\norganization costs, the Trustee will sell additional Securities to allow the Trust to fully reimburse the Sponsor. In that event, the\nnet asset value per Unit of the Trust will be reduced by the amount of additional Securities sold. Although the dollar amount of the reimbursement\ndue to the Sponsor will remain fixed and will never exceed the per Unit amount set forth for the Trust in “Notes to Statement of\nNet Assets,” this will result in a greater effective cost per Unit to Unit holders for the reimbursement to the Sponsor. To the\nextent actual organization costs are less than the estimated amount, only the actual organization costs will ultimately be charged to\nthe Trust. When Securities are sold to reimburse the Sponsor for organization costs, the Trustee will sell Securities, to the extent practicable,\nwhich will maintain the same proportionate relationship among the Securities contained in the Trust as existed prior to such sale.

Minimum Purchase.

The minimum amount per account you can\npurchase of the Trust is generally $1,000 worth of Units ($500 if you are purchasing Units for your Individual Retirement Account or any\nother qualified retirement plan), but such amounts may vary depending on your selling firm.

Maximum Sales Charge.

The maximum sales charge of 1.85% per Unit\nis comprised of a transactional sales charge and a creation and development fee. After the initial offering period the maximum sales charge\nwill be reduced by 0.50%, to reflect the amount of the previously charged creation and development fee.

Transactional Sales Charge.

The transactional sales charge you will\npay has both an initial and a deferred component.

Initial Sales Charge. The initial\nsales charge, which you will pay at the time of purchase, is equal to the difference between the maximum sales charge of 1.85% of the\nPublic Offering Price and the sum of the maximum remaining deferred sales charge and creation and development fee (initially $.185 per\nUnit). On the Initial Date of Deposit, and any other day the Public Offering Price per Unit equals $10.00, there is no initial sales charge.\nThereafter, you will pay an initial sales charge when the Public Offering Price per Unit exceeds $10.00 and as deferred sales charge and\ncreation and development fee payments are made.

Monthly\nDeferred Sales Charge. In addition, three monthly deferred sales charges of $.045 per Unit will be deducted from the Trust’s\nassets on approximately the twentieth day of each month from February 19, 2027 through April 20, 2027. If you buy Units at a price of\nless than $10.00 per Unit, the dollar amount of the deferred sales charge will not change, but the deferred sales charge on a percentage\nbasis will be more than 1.35% of the Public Offering Price.

Creation and Development Fee.

As\nSponsor, we will also receive, and the Unit holders will pay, a creation and development fee. See “Expenses and Charges” for\na description of the services provided for this fee. The creation and development fee is a charge of $.050 per Unit collected at the end\nof the initial offering period. If you buy Units at a price of less than $10.00 per Unit, the dollar amount of the creation and development\nfee will not change, but the creation and development fee on a percentage basis will be more than 0.50% of the Public Offering Price.

Discounts for Certain Persons.

The\nmaximum sales charge is 1.85% per Unit and the maximum dealer concession is 1.25% per Unit.

If\nyou are purchasing Units for an investment account, the terms of which provide that your registered investment advisor or registered broker/dealer\n(a) charges periodic fees in lieu of commissions; (b) charges for financial planning, investment advisory or asset management\nservices; or (c) charges a comprehensive “wrap fee” or similar fee for these or comparable services (“Fee Accounts”),\nyou will not be assessed the transactional sales charge described above on such purchases. These Units will be designated as Fee Account\nUnits and, depending upon the purchase instructions we receive, assigned either a Fee Account Cash CUSIP Number, if you elect to have\ndistributions paid to you, or a Fee Account Reinvestment CUSIP Number, if you elect to have distributions reinvested into additional Units\nof the Trust. Certain Fee Account Unit holders may be assessed transaction or other account fees on the purchase and/or redemption of\nsuch Units by their registered investment advisor, broker/dealer or other processing organizations for providing certain transaction or\naccount activities. Fee Account Units are not available for purchase in the secondary market. We reserve the right to limit or deny purchases\nof Units not subject to the transactional sales charge by investors whose frequent trading activity we determine to be detrimental to\nthe Trust.

Employees,\nofficers and directors (and immediate family members) of the Sponsor, our related companies, and dealers and their affiliates will purchase\nUnits at the Public Offering Price less the applicable dealer concession, subject to the policies of the related selling firm. Immediate\nfamily members include spouses, or the equivalent if recognized under local law, children or step-children under the age of 21 living\nin the same household, parents or step-parents and trustees, custodians or fiduciaries for the benefit of such persons. Only employees,\nofficers and directors of companies that allow their employees to participate in this employee discount program are eligible for the discounts.

You will be charged the deferred sales\ncharge per Unit regardless of the price you pay for your Units or whether you are eligible to receive any discounts. However, if the purchase\nprice of your Units was less than $10.00 per Unit or if you are eligible to receive a discount such that the maximum sales charge you\nmust pay is less than the applicable maximum deferred sales charge, including Fee Account Units, you will be credited additional Units\nwith a dollar value equal to the difference between your maximum sales charge and the maximum deferred sales charge at the time you buy\nyour Units. If you elect to have distributions reinvested into additional Units of the Trust, in addition to the reinvestment Units you\nreceive you will also be credited additional Units with a dollar value at the time of reinvestment sufficient to cover the amount of any\nremaining deferred sales charge and creation and development fee to be collected on such reinvestment Units. The dollar value of these\nadditional credited Units (as with all Units) will fluctuate over time, and may be less on the dates deferred sales charges or the creation\nand development fee are collected than their value at the time they were issued.

The Value of the Securities.

The Sponsor will determine the aggregate\nunderlying value of the Securities in the Trust as of the Evaluation Time on each business day and will adjust the Public Offering Price\nof the Units according to this valuation. This Public Offering Price will be effective for all orders received before the Evaluation Time\non each such day. If we or the Trustee receive orders for purchases, sales or redemptions after that time, or on a day which is not a\nbusiness day, they will be held until the next determination of price. The term “business day” as used in this prospectus\nshall mean any day on which the NYSE is open. For purposes of Securities and Unit settlement, the term business day does not include days\non which U.S. financial institutions are closed.

The aggregate underlying value of the Securities\nin the Trust will be determined as follows: if the Securities are listed on a national or foreign securities exchange or Nasdaq, Inc.,\ntheir value shall generally be based on the closing sale price on the exchange or system which is the principal market therefore (“Primary\nExchange”), which shall be deemed to be the NYSE if the Securities are listed thereon (unless the Sponsor deems such price inappropriate\nas the basis for evaluation). In the event a closing sale price on the Primary Exchange is not published, the Securities will be valued\nbased on the last trade price on the Primary Exchange. If no trades occur on the Primary Exchange for a specific trade date, the value\nwill be based on the closing sale price from, in the opinion of the Sponsor, an appropriate secondary exchange, if any. If no trades occur\non the Primary Exchange or any appropriate secondary exchange on a specific trade date, the Sponsor will determine the value of the Securities\nusing the best information available to the Sponsor, which may include the prior day’s evaluated price. If the Security is an American\nDepositary Receipt/ADR, Global Depositary Receipt/GDR or other similar security in which no trade occurs on the Primary Exchange or any\nappropriate secondary exchange on a specific trade date, the value will be based on the evaluated price of the underlying security, determined\nas set forth above, after applying the appropriate ADR/GDR ratio, the exchange rate and such other information which the Sponsor deems\nappropriate. For purposes of valuing Securities traded on Nasdaq, Inc., closing sale price shall mean the Nasdaq^® Official\nClosing Price as determined by Nasdaq, Inc. If the Securities are not so listed or, if so listed and the principal market therefore is\nother than on the Primary Exchange or any appropriate secondary exchange, the value shall generally be based on the current ask price\non the over-the-counter market (unless the Sponsor deems such price inappropriate as a basis for evaluation). If current ask prices are\nunavailable, the value is generally determined (a) on the basis of current ask prices for comparable securities, (b) by appraising\nthe value of the Securities on the ask side of the market, or (c) any combination of the above. If such prices are in a currency\nother than U.S. dollars, the value of such Security shall be converted to U.S. dollars based on current exchange rates (unless the Sponsor\ndeems such prices inappropriate as a basis for evaluation). If the Sponsor deems a price determined as set forth above to be inappropriate\nas the basis for evaluation, the Sponsor shall use such other information available to the Sponsor which it deems appropriate as the basis\nfor determining the value of a Security.

After the initial offering period is over,\nthe aggregate underlying value of the Securities will be determined as set forth above, except that bid prices are used instead of ask\nprices when necessary.

\n \n \n

Distribution of Units

We intend to qualify Units of the Trust\nfor sale in a number of states. All Units will be sold at the then current Public Offering Price.

The Sponsor compensates intermediaries,\nsuch as broker/dealers and banks, for their activities that are intended to result in sales of Units of the Trust. This compensation includes\ndealer concessions described in the following section and may include additional concessions and other compensation and benefits to broker/dealers\nand other intermediaries.

Dealer Concessions.

Dealers\nand other selling agents can purchase Units at prices which represent a concession or agency commission of 1.25% of the Public Offering\nPrice per Unit, subject to reductions set forth in “Public Offering—Discounts for Certain Persons.”

Eligible\ndealer firms and other selling agents who, during the previous consecutive 12-month period through the end of the most recent month, sold\nprimary market units of unit investment trusts sponsored by us in the dollar amounts shown below will be entitled to up to the following\nadditional sales concession on primary market sales of units during the current month of unit investment trusts sponsored by us:

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

Total sales\t (in millions) \t \t\t	Additional \nConcession
$25 but less than $100\t		0.035	%
$100 but less than $150\t		0.050	%
$150 but less than $250\t		0.075	%
$250 but less than $1,000\t		0.100	%

$5,000 but less than $7,500\t		0.150	%
$7,500 or more\t		0.175	%

Dealers\nand other selling agents will not receive a concession on the sale of Units which are not subject to a transactional sales charge, but\nsuch Units will be included in determining whether the above volume sales levels are met. Eligible dealer firms and other selling agents\ninclude clearing firms that place orders with First Trust and provide First Trust with information with respect to the representatives\nwho initiated such transactions. Eligible dealer firms and other selling agents will not include firms that solely provide clearing services\nto other broker/dealer firms or firms who place orders through clearing firms that are eligible dealers. We reserve the right to change\nthe amount of concessions or agency commissions from time to time. Certain commercial banks may be making Units of the Trust available\nto their customers on an agency basis. A portion of the transactional sales charge paid by these customers is kept by or given to the\nbanks in the amounts shown above.

Other Compensation and Benefits to Broker/Dealers.

The Sponsor, at its own expense and out\nof its own profits, currently provides additional compensation and benefits to broker/dealers who sell Units of this Trust and other First\nTrust products. This compensation is intended to result in additional sales of First Trust products and/or compensate broker/dealers and\nfinancial advisors for past sales. A number of factors are considered in determining whether to pay these additional amounts. Such factors\nmay include, but are not limited to, the level or type of services provided by the intermediary, the level or expected level of sales\nof First Trust products by the intermediary or its agents, the placing of First Trust products on a preferred or recommended product list,\naccess to an intermediary’s personnel, and other factors. The Sponsor makes these payments for marketing, promotional or related\nexpenses, including, but not limited to, expenses of entertaining retail customers and financial advisers, advertising, sponsorship of\nevents or seminars, obtaining information about the breakdown of unit sales among an intermediary’s representatives or offices,\nobtaining shelf space in broker/dealer firms and similar activities designed to promote the sale of the Sponsor’s products. The\nSponsor makes such payments to a substantial majority of intermediaries that sell First Trust products. The Sponsor may also make certain\npayments to, or on behalf of, intermediaries to defray a portion of their costs incurred for the purpose of facilitating Unit sales, such\nas the costs of developing or purchasing trading systems to process Unit trades. Payments of such additional compensation described in\nthis and the preceding paragraph, some of which may be characterized as “revenue sharing,” create a conflict of interest by\ninfluencing financial intermediaries and their agents to sell or recommend a First Trust product, including the Trust, over products offered\nby other sponsors or fund companies. These arrangements will not change the price you pay for your Units.

Advertising and Investment Comparisons.

Advertising materials regarding the Trust\nmay discuss several topics, including: developing a long-term financial plan; working with your financial professional; the nature and\nrisks of various investment strategies and unit investment trusts that could help you reach your financial goals; the importance of discipline;\nhow the Trust operates; how securities are selected; various unit investment trust features such as convenience and costs; and options\navailable for certain types of unit investment trusts. These materials may include descriptions of the principal businesses of the companies\nrepresented in the Trust, research analysis of why they were selected and information relating to the qualifications of the persons or\nentities providing the research analysis. In addition, they may include research opinions on the economy and industry sectors included\nand a list of investment products generally appropriate for pursuing those recommendations.

From time to time we may compare the estimated\nreturns of the Trust (which may show performance net of the expenses and charges the Trust would have incurred) and returns over specified\nperiods of other similar trusts we sponsor in our advertising and sales materials, with (1) returns on other taxable investments such\nas the common stocks comprising various market indexes, corporate or U.S. Government bonds, bank CDs and money market accounts or funds,\n(2) performance data from Morningstar, Inc. or (3) information from publications such as Money, The New York Times,\nU.S. News and World Report, Bloomberg Businessweek, Forbes or Fortune. The investment characteristics of the\nTrust differ from other comparative investments. You should not assume that these performance comparisons will be representative of the\nTrust’s future performance. We may also, from time to time, use advertising which classifies trusts or portfolio securities according\nto capitalization and/or investment style.

\n \n \n

The Sponsor’s Profits

We will receive a gross sales commission\nequal to the maximum transactional sales charge per Unit less any reduction as stated in “Public Offering.” We will also receive\nthe amount of any collected creation and development fee. Also, any difference between our cost to purchase the Securities and the price\nat which we sell them to the Trust is considered a profit or loss (see Note 2 of “Notes to Schedule of Investments”). During\nthe initial offering period, dealers and others may also realize profits or sustain losses as a result of fluctuations in the Public Offering\nPrice they receive when they sell the Units.

In maintaining a market for the Units,\nany difference between the price at which we purchase Units and the price at which we sell or redeem them will be a profit or loss to\nus.

\n \n \n

The Secondary Market

Although\nnot obligated, we may maintain a market for the Units after the initial offering period and continuously offer to purchase Units at prices\nbased on the Redemption Price per Unit.

We\nwill pay all expenses to maintain a secondary market, except fees to value Trust Securities and Trustee costs to transfer and record the\nownership of Units. We may discontinue purchases of Units at any time. If you wish to dispose of your Units, you should ask us for\nthe current market prices before making a tender for redemption to the Trustee. If you sell or redeem your Units before you have paid\nthe total deferred sales charge on your Units, you will have to pay the remainder at that time.

\n \n \n

How We Purchase Units

The\nTrustee will notify us of any tender of Units for redemption. If our bid at that time is equal to or greater than the Redemption Price\nper Unit, we may purchase the Units. You will receive your proceeds from the sale no later than if they were redeemed by the Trustee.\nWe may tender Units that we hold to the Trustee for redemption as any other Units. If we elect not to purchase Units, the Trustee may\nsell tendered Units in the over-the-counter market, if any. However, the amount you will receive is the same as you would have received\non redemption of the Units.

\n \n \n

Expenses and Charges

The\nestimated annual expenses of the Trust are listed under “Fee Table.” If actual expenses of the Trust exceed the estimate,\nthe Trust will bear the excess. The Trustee will pay operating expenses of the Trust from the Income Account of the Trust if funds are\navailable, and then from the Capital Account. The Income and Capital Accounts are non-interest-bearing to Unit holders, so the Trustee\nmay earn interest on these funds, thus benefiting from their use.

First\nTrust Advisors L.P., an affiliate of ours, acts as Portfolio Supervisor and will be compensated for providing portfolio supervisory services\nas well as bookkeeping and other administrative services to the Trust. In providing portfolio supervisory services, the Portfolio Supervisor\nmay purchase research services from a number of sources, which may include underwriters or dealers of the Trust. As Sponsor, we will be\ncompensated for providing evaluation services and we will receive brokerage fees when the Trust uses us (or an affiliate of ours) as agent\nin buying or selling Securities. As authorized by the Indenture, the Trustee may employ a subsidiary or affiliate of the Trustee to act\nas broker to execute certain transactions for the Trust. The Trust will pay for such services at standard commission rates.

The\nfees payable to the Sponsor, First Trust Advisors L.P. and the Trustee are based on the largest aggregate number of Units of the Trust\noutstanding at any time during the calendar year, except during the initial offering period, in which case these fees are calculated based\non the largest number of Units outstanding during the period for which compensation is paid. These fees may be adjusted for inflation\nwithout Unit holders’ approval, but in no case will the annual fees paid to us or our affiliates for providing services to all unit\ninvestment trusts be more than the actual cost of providing such services in such year.

As\nSponsor, we will receive a fee from the Trust for creating and developing the Trust, including determining the Trust’s objectives,\npolicies, composition and size, selecting service providers and information services and for providing other similar administrative and\nministerial functions. The “creation and development fee” is a charge of $.050 per Unit outstanding at the end of the initial\noffering period. The Trustee will deduct this amount from the Trust’s assets as of the close of the initial offering period. We\ndo not use this fee to pay distribution expenses or as compensation for sales efforts. This fee will not be deducted from your proceeds\nif you sell or redeem your Units before the end of the initial offering period.

In\naddition to the Trust’s operating expenses and those fees described above, the Trust may also incur the following charges:

•

All legal expenses of the Trustee according to its responsibilities under the Indenture;

•

The expenses and costs incurred by the Trustee to protect the Trust and your rights and interests\n(i.e., participating in litigation concerning a portfolio security) and the costs of indemnifying the Trustee;

•

Fees for any extraordinary services the Trustee performed under the Indenture;

•

Payment for any loss, liability or expense the Trustee incurred without negligence, bad faith\nor willful misconduct on its part, in connection with its acceptance or administration of the Trust;

•

Payment for any loss, liability or expenses we incurred without negligence, bad faith or willful\nmisconduct in acting as Sponsor of the Trust;

•

Foreign custodial and transaction fees (which may include compensation paid to the Trustee or\nits subsidiaries or affiliates), if any; and/or

•

All taxes and other government charges imposed upon the Securities or any part of the Trust.

The\nabove expenses and the Trustee’s annual fee are secured by a lien on the Trust. In addition, if there is not enough cash in the\nIncome or Capital Account, the Trustee has the power to sell Securities to make cash available to pay these charges which may result in\ncapital gains or losses to you. See “Tax Status.”

Tax Status

Federal Tax Matters.

This\nsection discusses some of the main U.S. federal income tax consequences of owning Units of the Trust as of the date of this prospectus.\nTax laws and interpretations change frequently, and this summary does not describe all of the tax consequences to all taxpayers. For example,\nthis summary generally does not describe your situation if you are a broker/dealer or other investor with special circumstances. In addition,\nthis section may not describe your state, local or non-U.S. tax consequences.

This federal income tax summary is based\nin part on the advice of counsel to the Sponsor. The Internal Revenue Service (“IRS”) could disagree with any conclusions\nset forth in this section. In addition, our counsel may not have been asked to review, and may not have reached a conclusion with respect\nto the federal income tax treatment of the assets to be deposited in the Trust. This summary may not be sufficient for you to use for\nthe purpose of avoiding penalties under federal tax law.

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

Trust Status.

Unit\ninvestment trusts maintain both Income and Capital Accounts, regardless of tax structure. Please refer to the “Income and Capital\nDistributions” section of the prospectus for more information.

The\nTrust intends to qualify as a “regulated investment company,” commonly known as a “RIC,” under the federal tax\nlaws. If the Trust qualifies as a RIC and distributes its income as required by the tax law, the Trust generally will not pay federal\nincome taxes. For federal income tax purposes, you are treated as the owner of the Trust Units and not of the assets held by the Trust.\n

Income from the Trust.

Trust\ndistributions are generally taxable. After the end of each year, you will receive a tax statement that separates the Trust’s distributions\ninto ordinary income dividends, capital gain dividends and return of capital. Income reported is generally net of expenses (but see “Treatment\nof Trust Expenses” below). Ordinary income dividends are generally taxed at your ordinary income tax rate, however, certain dividends\nreceived from the Trust may be taxed at the capital gains tax rates. Generally, all capital gain dividends are treated as long-term capital\ngains regardless of how long you have owned your Units. In addition, the Trust may make distributions that represent a return of capital\nfor tax purposes and will generally not be currently taxable to you, although they generally reduce your tax basis in your Units and thus\nincrease your taxable gain or decrease your loss when you dispose of your Units. The tax laws may require you to treat distributions made\nto you in January as if you had received them on December 31 of the previous year.

Some\ndistributions from the Trust may qualify as long-term capital gains, which, if you are an individual, is generally taxed at a lower rate\nthan your ordinary income and short-term capital gain income. The distributions from the Trust that you must take into account for federal\nincome tax purposes are not reduced by the amount used to pay a deferred sales charge, if any. Distributions from the Trust, including\ncapital gains, may also be subject to a “Medicare tax” if your adjusted gross income exceeds certain threshold amounts.

Certain Stock Dividends.

Ordinary\nincome dividends received by an individual Unit holder from a RIC such as the Trust are generally taxed at the same rates that apply to\nlong-term capital gains, provided certain holding period requirements are satisfied and provided the dividends are attributable to qualifying\ndividend income (“QDI”) received by the Trust itself. Dividends that do not meet these requirements will generally be taxed\nat ordinary income tax rates. After the end of the tax year, the Trust will provide a tax statement to its Unit holders reporting the\namount of any distribution which may be taken into account as a dividend which is eligible for the capital gains tax rates.

Unit\nholders that are corporations may be eligible for the dividends received deduction with respect to certain ordinary income dividends on\nUnits that are attributable to qualifying dividends received by the Trust from certain corporations.

Sale of Units.

If\nyou sell your Units (whether to a third party or to the Trust), you will generally recognize a taxable gain or loss. To determine the\namount of this gain or loss, you must subtract your (adjusted) tax basis in your Units from the amount you receive from the sale. Your\noriginal tax basis in your Units is generally equal to the cost of your Units, including sales charges. In some cases, however, you may\nhave to adjust your tax basis after you purchase your Units, in which case your gain would be calculated using your adjusted basis.

The\ntax statement you receive in regard to the sale or redemption of your Units may contain information about your basis in the Units and\nwhether any gain or loss recognized by you should be considered long-term or short-term capital gain. The information reported to you\nis based upon rules that do not take into consideration all of the facts that may be known to you or to your advisors. You should consult\nwith your tax advisor about any adjustments that may need to be made to the information reported to you in determining the amount of your\ngain or loss.

Distribution Reinvestment Option.

If\nyou elect to reinvest your distributions into additional Units, you will be treated as if you have received your distribution in an amount\nequal to the distribution you are entitled to. Your tax liability will be the same as if you received the distribution in cash. Also,\nthe reinvestment would generally be considered a purchase of new Units for federal income tax purposes.

Treatment of Trust Expenses.

Expenses\nincurred and deducted by the Trust will generally not be treated as income taxable to you. In some cases, however, you may be required\nto treat your portion of these Trust expenses as income. You may not be able to take a deduction for some or all of these expenses even\nif the cash you receive is reduced by such expenses.

Investments in Certain Non-U.S. Corporations.

A\nforeign corporation will generally be treated as a passive foreign investment company (“PFIC”) if 75% or more of its income\nis passive income or if 50% or more of its assets are held to produce passive income. If the Trust holds an equity interest in PFICs,\nthe Trust could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions from the PFICs,\neven if all the income or gain is distributed in a timely fashion to the Trust Unit holders. The Trust will not be able to pass through\nto its Unit holders any credit or deduction for such taxes if the taxes are imposed at the Trust level. The Trust may be able to make\nan election that could limit the tax imposed on the Trust. In this case, the Trust would recognize as ordinary income any increase in\nthe value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included\nin income.

Under\nthis election, the Trust might be required to recognize income in excess of its distributions from the PFICs and its proceeds from dispositions\nof PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into\naccount for purposes of determining the application of the 4% excise tax imposed on RICs that do not meet certain distribution thresholds.\nDividends paid by PFICs are not treated as QDI to shareholders of the PFICs.

Non-U.S. Investors.

If\nyou are a non-U.S. investor, distributions from the Trust treated as dividends will generally be subject to a U.S. withholding tax of\n30% of the distribution. Certain dividends, such as capital gains dividends and short-term capital gains dividends, may not be subject\nto U.S. withholding taxes. In addition, some non-U.S. investors may be eligible for a reduction or elimination of U.S. withholding taxes\nunder a treaty. However, the qualification for those exclusions may not be known at the time of the distribution and some excluded income\nmay be taken into consideration for alternative minimum tax purposes.

Separately,\nthe United States, pursuant to the Foreign Account Tax Compliance Act (“FATCA”) imposes a 30% tax on certain non-U.S. entities\nthat receive U.S. source interest or dividends if the non-U.S. entity does not comply with certain U.S. disclosure and reporting requirements.\nThis FATCA tax also currently applies to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends.\nHowever, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

It\nis the responsibility of the entity through which you hold your Units to determine the applicable withholding.

Foreign Tax Credit.

If\nthe Trust directly or indirectly invests in non-U.S. stocks, the tax statement that you receive may include an item showing foreign taxes\nthe Trust paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes. The Trust would have\nto meet certain IRS requirements in order to pass through credits to you.

In-Kind Distributions.

If\npermitted by this prospectus, as described in “Redeeming Your Units,” you may request an In-Kind Distribution of Trust assets\nwhen you redeem your Units. This distribution is subject to tax, and you will generally recognize gain or loss, generally based on the\nvalue at that time of the securities and the amount of cash received.

Rollovers.

If\nyou elect to have your proceeds from the Trust rolled over into a future series of the Trust, the exchange would generally be considered\na sale for federal income tax purposes.

You\nshould consult your tax advisor regarding potential foreign, state or local taxation with respect to your Units.

\n \n \n

Retirement Plans

You\nmay purchase Units of the Trust for:

•

Individual Retirement Accounts;

•

Keogh Plans;

•

Pension funds; and

•

Other tax-deferred retirement plans.

Generally,\nthe federal income tax on capital gains and income received in each of the above plans is deferred until you receive distributions. These\ndistributions are generally treated as ordinary income but may, in some cases, be eligible for special averaging or tax-deferred rollover\ntreatment. Before participating in a plan like this, you should review the tax laws regarding these plans and consult your attorney or\ntax advisor. Brokerage firms and other financial institutions offer these plans with varying fees and charges.

\n \n \n

Rights of Unit Holders

Unit Ownership.

Ownership\nof Units will not be evidenced by certificates. If you purchase or hold Units through a broker/dealer or bank, your ownership of Units\nwill be recorded in book-entry form at the Depository Trust Company (“DTC”) and credited on its records to your broker/dealer’s\nor bank’s DTC account. Transfer of Units will be accomplished by book entries made by DTC and its participants if the Units are\nregistered to DTC or its nominee, Cede & Co. DTC will forward all notices and credit all payments received in respect of the Units\nheld by the DTC participants. You will receive written confirmation of your purchases and sales of Units from the broker/dealer or bank\nthrough which you made the transaction. You may transfer your Units by contacting the broker/dealer or bank through which you hold your\nUnits.

Unit Holder Reports.

The\nTrustee will prepare a statement detailing the per Unit amounts (if any) distributed from the Income Account and Capital Account in connection\nwith each distribution. In addition, at the end of each calendar year, the Trustee will prepare a statement which contains the following\ninformation:

•

A summary of transactions in the Trust for the year;

•

A list of any Securities sold during the year and the Securities held at the end of that year\nby the Trust;

•

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

•

Amounts of income and capital distributed during the year.

By\nFebruary 15th yearly, the Annual Reports are posted to the Sponsor’s website (www.ftportfolios.com) in the UIT Tax Center and retrievable\nby CUSIP. You may also request one be sent to you by calling the Sponsor at 800–621–1675, dept. code 2. In addition, you may\nalso request from the Trustee copies of the evaluations of the Securities as prepared by the Sponsor to enable you to comply with applicable\nfederal and state tax reporting requirements.

\n \n \n

Income and Capital Distributions

You\nwill be eligible to receive distributions, if any, on your Units only after you become a Record Owner. The Trustee will credit dividends\nreceived on the Trust’s Securities to the Income Account of the Trust. All other receipts, such as return of capital or capital\ngain dividends, are credited to the Capital Account of the Trust. Dividends received on foreign Securities, if any, are converted into\nU.S. dollars at the applicable exchange rate.

The Trustee will distribute money from\nthe Income Account, as determined at the semi-annual Income Account Distribution Record Date, semi-annually on the twenty-fifth day of\neach June and December to Unit holders of record on the tenth day of such months provided the amount equals at least $1.00 per 100 Units.\nNo Income Account distribution will be paid if accrued expenses of the Trust exceed amounts in the Income Account on the Income Account\nDistribution Dates. Distribution amounts will vary with changes in the Trust’s fees and expenses, in dividends received and with\nthe sale of Securities. The Trustee will distribute money in the Capital Account monthly on the twenty-fifth day of each month to Unit\nholders of record on the tenth day of such month if the amount available for distribution from that account equals at least $1.00 per\n100 Units. In any case, the Trustee may distribute funds in the Capital Account in December of each year to avoid imposition of any income\nor excise taxes on undistributed income in the Trust and will distribute funds as part of the final liquidation distribution.

If an Income or Capital Account distribution\ndate is a day on which the NYSE is closed, the distribution will be made on the next day the stock exchange is open. Distributions are\npaid to Unit holders of record determined as of the close of business on the Record Date for that distribution or, if the Record Date\nis a day on which the NYSE is closed, the first preceding day on which the exchange is open.

We anticipate that there will be enough\nmoney in the Capital Account of the Trust to pay the deferred sales charge to the Sponsor. If not, the Trustee may sell Securities to\nmeet the shortfall.

Within a reasonable time after the Trust\nis terminated, unless you are a Rollover Unit holder, you will receive a pro rata share of the money from the sale of the Securities and\namounts in the Income and Capital Accounts. All Unit holders will receive a pro rata share of any other assets remaining in your Trust,\nafter deducting any unpaid expenses.

The Trustee may establish reserves (the\n“Reserve Account”) within the Trust to cover anticipated state and local taxes or any governmental charges to be paid out\nof the Trust.

Distribution Reinvestment Option.\nYou may elect to have each distribution of income and/or capital reinvested into additional Units of the Trust by notifying your broker/dealer\nor bank within the time period required by such entities so that they can notify the Trustee of your election at least 10 days before\nany Record Date. Each later distribution of income and/or capital on your Units will be reinvested by the Trustee into additional Units\nof such Trust. There is no sales charge on Units acquired through the Distribution Reinvestment Option, as discussed under “Public\nOffering.” This option may not be available in all states. Each reinvestment plan is subject to availability or limitation by the\nSponsor and each broker/dealer or selling firm. The Sponsor or broker/dealers may suspend or terminate the offering of a reinvestment\nplan at any time. Because the Trust may begin selling Securities nine business days prior to the Mandatory Termination Date, reinvestment\nis not available during this period. Please contact your financial professional for additional information. Please note that even if\nyou reinvest distributions, they are still considered distributions for income tax purposes.

\n \n \n

Redeeming Your Units

You may redeem all or a portion of your\nUnits at any time by sending a request for redemption to your broker/dealer or bank through which you hold your Units. No redemption fee\nwill be charged, but you are responsible for any governmental charges that apply. Certain broker/dealers may charge a transaction fee\nfor processing redemption requests. One business day after the day you tender your Units (the “Date of Tender”) you will receive\ncash in an amount for each Unit equal to the Redemption Price per Unit calculated at the Evaluation Time on the Date of Tender.

The Date of Tender is considered to be\nthe date on which your redemption request is received by the Trustee from the broker/dealer or bank through which you hold your Units\n(if such day is a day the NYSE is open for trading). However, if the redemption request is received after 4:00 p.m. Eastern time (or after\nany earlier closing time on a day on which the NYSE is scheduled in advance to close at such earlier time), the Date of Tender is the\nnext day the NYSE is open for trading.

Any amounts paid on redemption representing\nincome will be withdrawn from the Income Account if funds are available for that purpose, or from the Capital Account. All other amounts\npaid on redemption will be taken from the Capital Account.

If you tender for redemption at least 2,500\nUnits, or such larger amount as required by your broker/dealer or bank, rather than receiving cash, you may elect to receive an In-Kind\nDistribution in an amount equal to the Redemption Price per Unit by making this request to your broker/dealer or bank at the time of tender.\nHowever, to be eligible to participate in the In-Kind Distribution option at redemption, Unit holders must hold their Units through the\nend of the initial offering period. No In-Kind Distribution requests submitted during the 10 business days prior to the Trust’s\nMandatory Termination Date will be honored. Where possible, the Trustee will make an In-Kind Distribution by distributing each of the\nSecurities in book-entry form to your bank’s or broker/dealer’s account at DTC. The Trustee will subtract any customary transfer\nand registration charges from your In-Kind Distribution. As a tendering Unit holder, you will receive your pro rata number of whole shares\nof Securities that make up the portfolio, and cash from the Capital Account equal to the fractional shares to which you are entitled.

If\nyou elect to receive an In-Kind Distribution of Securities, you should be aware that it will be considered a taxable event at the time\nyou receive the Securities. See “Tax Status” for additional information.

The\nTrustee may sell Securities to make funds available for redemption. If Securities are sold, the size and diversification of the Trust\nwill be reduced. These sales may result in lower prices than if the Securities were sold at a different time.

Your\nright to redeem Units (and therefore, your right to receive payment) may be delayed:

•

If the NYSE is closed (other than customary weekend and holiday closings);

•

If the SEC determines that trading on the NYSE is restricted or that an emergency exists making\nsale or evaluation of the Securities not reasonably practical; or

•

For any other period permitted by SEC order.

The\nTrustee is not liable to any person for any loss or damage which may result from such a suspension or postponement.

The Redemption Price.

The\nRedemption Price per Unit is determined by the Trustee by:

adding

cash in the Income and Capital Accounts of the Trust not designated to purchase Securities;

the aggregate underlying value of the Securities held in the Trust; and

dividends receivable on the Securities trading ex-dividend as of the date of computation; and

deducting

any applicable taxes or governmental charges that need to be paid out of the Trust;

any amounts owed to the Trustee for its advances;

estimated accrued expenses of the Trust, if any;

cash held for distribution to Unit holders of record of the Trust as of the business day before\nthe evaluation being made;

liquidation costs for foreign Securities, if any; and

other liabilities incurred by the Trust; and

dividing

the result by the number of outstanding Units of the Trust.

Any\nremaining deferred sales charge on the Units when you redeem them will be deducted from your redemption proceeds. In addition, until they\nare collected, the Redemption Price per Unit will include estimated organization costs as set forth under “Fee Table.”

\n \n \n

Investing in a New Trust

When the Trust is about to terminate, you\nmay have the option to roll your proceeds into the next series of the Trust (the “New Trust”) if one is available. We intend\nto create the New Trust in conjunction with the termination of the Trust and plan to apply the same strategy we used to select the portfolio\nfor the Trust to the New Trust.

If you wish to have the proceeds from your\nUnits rolled into a New Trust you must notify the broker/dealer where your Units are held of your election prior to that firm’s\ncut-off date. If you make this election you will be considered a “Rollover Unit holder.”

Once all of the Securities are sold in\nconnection with the termination of the Trust, as described in “Amending or Terminating the Indenture,” your proceeds, less\nany brokerage fees, governmental charges or other expenses involved in the sales, will be used to buy units of a New Trust or trust with\na similar investment strategy that you have selected, provided such trusts are registered and being offered. Accordingly, proceeds may\nbe uninvested for up to several days. Units purchased with rollover proceeds will generally be purchased subject to the sales charge set\nforth in the prospectus for such trust.

We intend to create New Trust units as\nquickly as possible, depending on the availability of the securities contained in a New Trust’s portfolio. Rollover Unit holders\nwill be given first priority to purchase New Trust units. We cannot, however, assure the exact timing of the creation of New Trust units\nor the total number of New Trust units we will create. Any proceeds not invested on behalf of Rollover Unit holders in New Trust units\nwill be distributed within a reasonable time after such occurrence. Although we believe that enough New Trust units can be created, monies\nin a New Trust may not be fully invested on the next business day.

Please note that there are certain tax\nconsequences associated with becoming a Rollover Unit holder. See “Tax Status.” We may modify, amend or terminate this rollover\noption upon 60 days notice.

\n \n \n

Removing Securities from the Trust

The\nportfolio of the Trust is not managed. However, we may, but are not required to, direct the Trustee to dispose of a Security in certain\nlimited circumstances, including situations in which:

•

The issuer of the Security defaults in the payment of a declared dividend;

•

Any action or proceeding prevents the payment of dividends;

•

There is any legal question or impediment affecting the Security;

•

The issuer of the Security has breached a covenant which would affect the payment of dividends,\nthe issuer’s credit standing, or otherwise damage the sound investment character of the Security;

•

The issuer has defaulted on the payment of any other of its outstanding obligations;

•

There has been a public tender offer made for a Security or a merger or acquisition is announced\naffecting a Security, and that in our opinion the sale or tender of the Security is in the best interest of Unit holders;

•

The sale of Securities is necessary or advisable (i) in order to maintain the qualification of the Trust as a “regulated investment\ncompany” in the case of the Trust which has elected to qualify as such or (ii) to provide funds to make any distribution for a taxable\nyear in order to avoid imposition of any income or excise taxes on undistributed income in the Trust which is a “regulated investment\ncompany”;

•

The price of the Security has declined to such an extent, or such other credit factors exist,\nthat in our opinion keeping the Security would be harmful to the Trust;

•

As a result of the ownership of the Security, the Trust or its Unit holders would be a direct\nor indirect shareholder of a passive foreign investment company; or

•

The sale of the Security is necessary for the Trust to comply with such federal and/or state\nlaws, regulations and/or regulatory actions and interpretations which may be in effect from time to time.

Except\nfor instances in which the Trust acquires Replacement Securities, as described in “The FT Series,” the Trust will generally\nnot acquire any securities or other property other than the Securities. The Trustee, on behalf of the Trust and at the direction of the\nSponsor, will vote for or against any offer for new or exchanged securities or property in exchange for a Security, such as those acquired\nin a merger or other transaction. If such exchanged securities or property are acquired by the Trust, at our instruction, they will either\nbe sold or held in the Trust. In making the determination as to whether to sell or hold the exchanged securities or property we may get\nadvice from the Portfolio Supervisor. Any proceeds received from the sale of Securities, exchanged securities or property will be credited\nto the Capital Account of the Trust for distribution to Unit holders or to meet redemption requests. The Trustee may retain and pay us\nor an affiliate of ours to act as agent for the Trust to facilitate selling Securities, exchanged securities or property from the Trust.\nIf we or our affiliate act in this capacity, we will be held subject to the restrictions under the 1940 Act. When acting in an agency\ncapacity, we may select various broker/dealers to execute securities transactions on behalf of the Trust, which may include broker/dealers\nwho sell Units of the Trust. We do not consider sales of Units of the Trust or any other products sponsored by First Trust as a factor\nin selecting such broker/dealers. As authorized by the Indenture, the Trustee may also employ a subsidiary or affiliate of the Trustee\nto act as broker in selling such Securities or property. The Trust will pay for these brokerage services at standard commission rates.

The\nTrustee may sell Securities designated by us, or, absent our direction, at its own discretion, in order to meet redemption requests or\npay expenses. In designating Securities to be sold, we will try to maintain the proportionate relationship among the Securities. If this\nis not possible, the composition and diversification of the Trust may be changed.

\n \n \n

Amending or Terminating the Indenture

Amendments.\nThe Indenture may be amended by us and the Trustee without your consent:

•

To cure ambiguities;

•

To correct or supplement any defective or inconsistent provision;

•

To make any amendment required by any governmental agency; or

•

To make other changes determined not to be adverse to your best interests (as determined by\nus and the Trustee).

Termination.\nAs provided by the Indenture, the Trust will terminate on the Mandatory Termination Date as stated in the “Summary of Essential\nInformation.” The Trust may be terminated earlier:

•

Upon the consent of 100% of the Unit holders of the Trust;

•

If the value of the Securities owned by the Trust as shown by any evaluation is less than the\nlower of $2,000,000 or 20% of the total value of Securities deposited in the Trust during the initial offering period (“Discretionary\nLiquidation Amount”); or

•

In the event that Units of the Trust not yet sold aggregating more than 60% of the Units of\nthe Trust are tendered for redemption by underwriters, including the Sponsor.

If\nthe Trust is terminated due to this last reason, we will refund your entire sales charge; however, termination of the Trust before the\nMandatory Termination Date for any other stated reason will result in all remaining unpaid deferred sales charges on your Units being\ndeducted from your termination proceeds. For various reasons, the Trust may be reduced below the Discretionary Liquidation Amount and\ncould therefore be terminated before the Mandatory Termination Date.

Unless\nterminated earlier, the Trustee may begin to sell Securities in connection with the termination of the Trust as early as nine business\ndays prior to, but will sell Securities no later than, the Mandatory Termination Date. We will determine the manner and timing of the\nsale of Securities. Because the Trustee must sell the Securities within a relatively short period of time, the sale of Securities as part\nof the termination process may result in a lower sales price than might otherwise be realized if such sale were not required at this time.

If\nyou do not elect to participate in the rollover option, you will receive a cash distribution from the sale of the remaining Securities,\nalong with your interest in the Income and Capital Accounts, within a reasonable time after the Trust is terminated. The Trustee will\ndeduct from the Trust any accrued costs, expenses, advances or indemnities provided for by the Indenture, including estimated compensation\nof the Trustee and costs of liquidation and any amounts required as a reserve to pay any taxes or other governmental charges.

•

Appoint a successor sponsor, paying them a reasonable rate not more than that stated by the SEC;

Dividends			1
Foreign Securities			1
Small and/or Mid Capitalization Companies			2

Risk Factors

Securities.\nAn investment in Units should be made with an understanding of the risks which an investment in common stocks entails, including the risk\nthat the financial condition of the issuers of the Securities or the general condition of the relevant stock market may worsen, and the\nvalue of the Securities and therefore the value of the Units may decline. Common stocks are especially susceptible to general stock market\nmovements and to volatile increases and decreases of value, as market confidence in and perceptions of the issuers change. These perceptions\nare based on unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and\ninterest rates, economic expansion or contraction, and global or regional political, economic or banking crises.

Dividends.\nShareholders of common stocks have rights to receive payments from the issuers of those common stocks that are generally subordinate to\nthose of creditors of, or holders of debt obligations or preferred stocks of, such issuers. Shareholders of common stocks have a right\nto receive dividends only when and if, and in the amounts, declared by the issuer’s board of directors and have a right to participate\nin amounts available for distribution by the issuer only after all other claims on the issuer have been paid or provided for. Common stocks\ndo not represent an obligation of the issuer and, therefore, do not offer any assurance of income or provide the same degree of protection\nof capital as do debt securities. The issuance of additional debt securities or preferred stock will create prior claims for payment of\nprincipal, interest and dividends which could adversely affect the ability and inclination of the issuer to declare or pay dividends on\nits common stock or the rights of holders of common stock with respect to assets of the issuer upon liquidation or bankruptcy. Cumulative\npreferred stock dividends must be paid before common stock dividends, and any cumulative preferred stock dividend omitted is added to\nfuture dividends payable to the holders of cumulative preferred stock. Preferred stockholders are also generally entitled to rights on\nliquidation which are senior to those of common stockholders.

Foreign Issuers.\nSince certain of the Securities held by the Trust consist of, or invest in, securities issued by foreign entities, an investment in the\nTrust involves certain investment risks that are different in some respects from an investment in a trust which invests solely in the\nsecurities of domestic entities. These investment risks include future political or governmental restrictions which might adversely affect\nthe payment or receipt of payment of dividends on the relevant Securities, the possibility that the financial condition of the issuers\nof the Securities may become impaired or that the general condition of the relevant stock market may worsen (both of which would contribute\ndirectly to a decrease in the value of the Securities and thus in the value of the Units), the limited liquidity and relatively small\nmarket capitalization of the relevant securities market, expropriation or confiscatory taxation, economic uncertainties and foreign currency\ndevaluations and fluctuations. In addition, for foreign issuers that are not subject to the reporting requirements of the Securities Exchange\nAct of 1934, as amended, there may be less publicly available information than is available from a domestic issuer. Also, foreign issuers\nare not necessarily subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to\nthose applicable to domestic issuers. The securities of many foreign issuers are less liquid and their prices more volatile than securities\nof comparable domestic issuers. In addition, fixed brokerage commissions and other transaction costs on foreign securities exchanges are\ngenerally higher than in the United States and there is generally less government supervision and regulation of exchanges, brokers and\nissuers in foreign countries than there is in the United States. However, due to the nature of the issuers of the Securities selected\nfor the Trust, the Sponsor believes that adequate information will be available to allow the Supervisor to provide portfolio surveillance\nfor the Trust.

Securities\nissued by non-U.S. issuers may pay interest and/or dividends in foreign currencies and may be principally traded in foreign currencies.\nTherefore, there is a risk that the U.S. dollar value of these interest and/or dividend payments and/or securities will vary with fluctuations\nin foreign exchange rates.

On the basis of the best\ninformation available to the Sponsor at the present time, none of the Securities in the Trust are subject to exchange control restrictions\nunder existing law which would materially interfere with payment to the Trust of dividends due on, or proceeds from the sale of, the Securities.\nHowever, there can be no assurance that exchange control regulations might not be adopted in the future which might adversely affect payment\nto the Trust. The adoption of exchange control regulations and other legal restrictions could have an adverse impact on the marketability\nof international securities in the Trust and on the ability of the Trust to satisfy its obligation to redeem Units tendered to the Trustee\nfor redemption. In addition, restrictions on the settlement of transactions on either the purchase or sale side, or both, could cause\ndelays or increase the costs associated with the purchase and sale of the foreign Securities and correspondingly could affect the price\nof the Units.

Investors should be aware\nthat it may not be possible to buy all Securities at the same time because of the unavailability of any Security, and restrictions applicable\nto the Trust relating to the purchase of a Security by reason of the federal securities laws or otherwise.

Foreign securities generally\nhave not been registered under the Securities Act of 1933 and may not be exempt from the registration requirements of such Act. Sales\nof non-exempt Securities by the Trust in the United States securities markets are subject to severe restrictions and may not be practicable.\nAccordingly, sales of these Securities by the Trust will generally be effected only in foreign securities markets. Although the Sponsor\ndoes not believe that the Trust will encounter obstacles in disposing of the Securities, investors should realize that the Securities\nmay be traded in foreign countries where the securities markets are not as developed or efficient and may not be as liquid as those in\nthe United States. The value of the Securities will be adversely affected if trading markets for the Securities are limited or absent.

Small\nand/or Mid Capitalization Companies. While historically stocks of small and mid capitalization companies have outperformed the stocks\nof large companies, the former have customarily involved more investment risk as well. Such companies may have limited product lines,\nmarkets or financial resources; may lack management depth or experience; and may be more vulnerable to adverse general market or economic\ndevelopments than large companies. Some of these companies may distribute, sell or produce products which have recently been brought to\nmarket and may be dependent on key personnel.

The\nprices of small and mid cap company securities are often more volatile than prices associated with large company issues, and can display\nabrupt or erratic movements at times, due to limited trading volumes and less publicly available information. Also, because such companies\nnormally have fewer shares outstanding and these shares trade less frequently than large companies, it may be more difficult for the Trusts\nwhich contain these Securities to buy and sell significant amounts of such shares without an unfavorable impact on prevailing market prices.

Undertaking

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