File No. 333-198351 CIK #1576549 SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 AMENDMENT NO. 2 TO REGISTRATION STATEMENT ON FORM S-6 For Registration under the Securities Act of 1933 of Securities of Unit Investment Trusts Registered on Form N-8B-2. A. Exact Name of Trust: INVESCO UNIT TRUSTS, MUNICIPAL SERIES 1230 B. Name of Depositor: INVESCO CAPITAL MARKETS, INC. C. Complete address of Depositor's principal executive offices: 11 Greenway Plaza Houston, Texas 77046-1173 D. Name and complete address of agents for service: PAUL HASTINGS LLP INVESCO CAPITAL MARKETS, INC. Attention: Michael R. Rosella, Esq. Attention: John M. Zerr, Esq. 75 East 55th Street 11 Greenway Plaza New York, New York 10022 Houston, Texas 77046-1173 E. Title of securities being registered: Units of fractional undivided beneficial interest. F. Approximate date of proposed sale to the public: AS SOON AS PRACTICABLE AFTER THE EFFECTIVE DATE OF THE REGISTRATION STATEMENT / X / Check box if it is proposed that this filing will become effective immediately upon filing on May 26, 2015, pursuant to Rule 487. Investment Grade Municipal Trust, 7-13 Year Series 60 Investment Grade Municipal Trust, 7-13 Year Series 60 invests in a portfolio of tax-exempt municipal bonds. The Trust seeks to provide federal tax-exempt income and to preserve capital. The Trust is a unit investment trust included in Invesco Unit Trusts, Municipal Series 1230. Monthly Distributions ------------- Estimated Current Return: 3.48% Estimated Long Term Return: 2.50% Estimated current return shows the estimated cash you should receive each year divided by the Unit price. Estimated long term return shows the estimated return over the estimated life of your Trust. These estimates are as of the opening of business on the Date of Deposit and will vary thereafter. We base this estimate on an average of the bond yields over their estimated life. This estimate also reflects the sales charge and estimated expenses. We derive the average yield for your portfolio by weighting each bond's yield by its value and estimated life. Unlike estimated current return, estimated long term return accounts for maturities, discounts and premiums of the bonds. These estimates show a comparison rather than a prediction of returns. No return calculation can predict your actual return. Your actual return may vary from these estimates. May 26, 2015 You should read this prospectus and retain it for future reference. -------------------------------------------------------------------------------- The Securities and Exchange Commission has not approved or disapproved of the Trust Units or passed upon the adequacy or accuracy of this prospectus. Any contrary representation is a criminal offense. INVESCO Investment Objective. The Trust seeks to provide federal tax-exempt income and to preserve capital. Principal Investment Strategy. The Trust invests in a portfolio of municipal bonds issued by or on behalf of states and territories of the United States, and political subdivisions and authorities thereof, the interest on which is, in the opinion of recognized bond counsel to the issuing authorities, excludable from gross income for federal personal income tax purposes under existing law. In selecting bonds for the Trust, the Sponsor considered the following factors, among others: o all ratings provided for the bonds must be at least "BBB-" if issued by either Standard & Poor's or Fitch Ratings, and at least "Baa3" if issued by Moody's Investors Service, Inc. or, in the case of a bond with no issued ratings, such a bond has credit characteristics sufficiently similar to those of comparable bonds that were so rated as to be acceptable for acquisition by the Trust in the opinion of the Sponsor; o the prices of the bonds relative to other bonds of comparable quality and maturity; o the current income provided by the bonds; o the diversification of bonds as to purpose of issue and location of issuer; and o the probability of early return of principal or high legal or event risk. The portfolio generally consists of bonds maturing approximately 7 to 13 years from the Date of Deposit. Following the Date of Deposit, a bond may cease to be rated or its rating may be reduced, even to below "investment grade" ("BBB-" or "Baa3"), and the Trust could continue to hold such bond. See "Trust Administration--Portfolio Administration". Principal Risks. As with all investments, you can lose money by investing in the Trust. The Trust also might not perform as well as you expect. This can happen for reasons such as these: o Bond prices will fluctuate. The value of your investment may fall over time. o The value of the bonds will generally fall if interest rates, in general, rise. No one can predict whether interest rates will rise or fall in the future. o A bond issuer or insurer may be unable to make interest and/or principal payments in the future. o The financial condition of an issuer may worsen or its credit ratings may drop, resulting in a reduction in the value of your Units. This may occur at any point in time, including during the primary offering period. o A bond issuer might prepay or "call" a bond before its stated maturity. If this happens, the Trust will distribute the principal to you but future interest distributions will fall. A bond's call price could be less than the price the Trust paid for the bond. If enough bonds are called, the Trust could terminate earlier than expected. o We do not actively manage the Trust's portfolio. Except in limited circumstances, the Trust will hold the same bonds even if the market value declines.

This could include a call or sale at a price below par value. We cannot guarantee that the value of your Units will equal the principal amount of bonds per Unit when you redeem them or when your Trust terminates. (2) During the initial offering period, part of the value of the Units represents an amount of cash deposited to pay all or a portion of the costs of organizing the Trust. The estimated organization costs per Unit will be deducted from the assets of the Trust at the earlier of six months after the Date of Deposit or the end of the initial offering period. If Units are redeemed prior to any such reduction, these costs will not be deducted from the redemption proceeds. Organization costs are not included in the Public Offering Price per Unit for purposes of calculating the sales charge. (3) After the first settlement date (May 29, 2015), you will pay accrued interest from this date to your settlement date less interest distributions. (4) This shows estimated expenses in the first year other than organization costs. Organization costs are not deducted from interest income. (5) Your Trust assesses this fee per $1,000 principal amount of bonds. Your Trust assesses other fees per Unit. (6) We base this amount on estimated cash flows per Unit. This amount will vary with changes in expenses, interest rates and maturity, call or sale of bonds. The Information Supplement includes the estimated cash flows.

Notes to Portfolio (1) The bonds are represented by "regular way" or "when issued" contracts for the performance of which an irrevocable letter of credit, obtained from an affiliate of the Trustee, has been deposited with the Trustee. Contracts to acquire the bonds were entered into during the period from March 5, 2015 to May 26, 2015. (2) The Offering Price to Trust of the bonds is based on the offering side valuation as of the opening of business on the Date of Deposit determined by the Evaluator, a third party valuation provider, on the basis set forth under "Public Offering--Unit Price". In accordance with FASB Accounting Standards Codification ("ASC"), ASC 820, Fair Value Measurements and Disclosures, the Trust's investments are classified as Level 2, which refers to security prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing a security. These may include quoted market prices for similar securities, interest rates, prepayment speeds and credit risk. The cost of the bonds to the Sponsor for the Trust is $6,161,349 and the Sponsor's profit or (loss) is $35,273. The Sponsor may have entered into contracts which hedge interest rate fluctuations on certain bonds. The cost of any such contracts and the corresponding gain or loss as of the evaluation time of the bonds is included in the Cost to Sponsor. Bonds marked by "##" following the maturity date have been purchased on a "when, as and if issued" or "delayed delivery" basis. Interest on these bonds begins accruing to the benefit of Unitholders on their respective dates of delivery. Delivery is expected to take place at various dates after the first settlement date. "#" prior to the coupon rate indicates that the bond was issued at an original issue discount. See "The Trusts--Risk Factors". The tax effect of bonds issued at an original issue discount is described in "Federal Tax Status". (3) All ratings are by Standard & Poor's and Moody's, respectively, unless otherwise indicated. "*" indicates a security rating by Fitch. "NR" indicates that the rating service did not provide a rating for that bond. For a brief description of the ratings see "Description of Ratings" in the Information Supplement. (4) This is the year in which each bond is initially or currently callable and the call price for that year. Each bond continues to be callable at declining prices thereafter (but not below par value) except for original issue discount bonds which are redeemable at prices based on the issue price plus the amount of original issue discount accreted to redemption date plus, if applicable, some premium, the amount of which will decline in subsequent years. "S.F." indicates a sinking fund is established with respect to an issue of bonds. The bonds may also be subject to redemption without premium at any time pursuant to extraordinary optional or mandatory redemptions if certain events occur. See "The Trusts--Risk Factors". Underwriting. The Underwriters named below have purchased Units in the following amounts from the Sponsor, the sole and exclusive principal underwriter. See "Public Offering--Sponsor and Underwriter Compensation".

The statement of condition is the responsibility of the Sponsor. Our responsibility is to express an opinion on such statement of condition based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of condition is free of material misstatement. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of condition, assessing the accounting principles used and significant estimates made by the Sponsor, as well as evaluating the overall statement of condition presentation. Our procedures included confirmation with The Bank of New York Mellon, Trustee, of cash or an irrevocable letter of credit deposited for the purchase of securities as shown in the statement of condition as of May 26, 2015. We believe that our audit of the statement of condition provides a reasonable basis for our opinion. In our opinion, the statement of condition referred to above presents fairly, in all material respects, the financial position of Investment Grade Municipal Trust, 7-13 Year Series 60 (included in Invesco Unit Trusts, Municipal Series 1230) as of May 26, 2015, in conformity with accounting principles generally accepted in the United States of America. New York, New York /s/ GRANT THORNTON LLP May 26, 2015 Statement of Condition As of the opening of business on May 26, 2015 INVESTMENT IN BONDS Contracts to purchase bonds (1)(2) $ 6,196,622 Accrued interest to the first settlement date (1)(2) 39,021 Cash (3) 36,738 ------------- Total $ 6,272,381 ============= LIABILITY AND INTEREST OF UNITHOLDERS Liability-- Accrued interest payable to Sponsor (1)(2) $ 39,021 Organization costs (3) 36,738 Interest of Unitholders-- Cost to investors 6,425,009 Less: Gross underwriting commission 191,649 Less: Organization costs (3) 36,738 ------------- Net interest to Unitholders (1)(2) 6,196,622 ------------- Total $ 6,272,381 ============= Units outstanding 5,670 ============= Net asset value per Unit $ 1,092.88 ============= ----------------- (1) The value of the bonds is determined by Standard & Poor's Securities Evaluations, Inc. on the bases set forth under "Public Offering--Unit Price". The contracts to purchase bonds are collateralized by an irrevocable letter of credit in an amount sufficient to satisfy such contracts. (2) The Trustee will advance the amount of the net interest accrued to the first settlement date to the Trust for distribution to the Sponsor as the Unitholder of record as of such date. (3) A portion of the public offering price represents an amount of cash sufficient to pay for all or a portion of the costs incurred in establishing the Trust. The amount of these costs are set forth under "Summary of Essential Financial Information--Expenses". A distribution will be made as of the earlier of six months after the Date of Deposit or the close of the initial offering period to an account maintained by the Trustee from which the organization expense obligation of the investors will be satisfied. To the extent that actual organization costs of the Trust are greater than the estimated amount, only the estimated organization costs added to the public offering price will be reimbursed to the Sponsor and deducted from the net assets of the Trust. THE TRUSTS -------------------------------------------------------------------------------- General. Your Trust is one of several unit investment trusts created under the name Invesco Unit Trusts, Municipal Series. The Trusts were created under the laws of the State of New York pursuant to a Trust Indenture and Agreement (the "Trust Agreement"), dated the date of this prospectus (the "Date of Deposit") among Invesco Capital Markets, Inc. as Sponsor, Invesco Investment Advisers LLC, as Supervisor, Standard & Poor's Securities Evaluations, Inc., as Evaluator, and The Bank of New York Mellon, as Trustee. The Trusts are separate portfolios of interest-bearing obligations issued by or on behalf of states and territories of the United States, and political subdivisions and authorities thereof, the interest on which is, in the opinion of recognized bond counsel to the issuing authorities, excludable from gross income for Federal income tax purposes under existing law. All issuers of bonds in a "State Trust" are located in the state for which the Trust is named or in United States territories or possessions and their public authorities; consequently, in the opinion of recognized bond counsel to the bond issuers, the interest earned on the bonds is exempt to the extent indicated in this prospectus from state and local taxes. With the exception of New York Trusts, Units of a State Trust may be purchased only by residents of the state for which the Trust is named. Units of a New York Trust may be purchased by residents of New York, Connecticut, Florida and New Jersey. Trusts that hold only insured bonds are referred to herein as "Insured Trusts." "Intermediate-Term Trust" refers to an Investment Grade Municipal Trust which is designated as a "7-13 year series" in the name of such Trust. Trusts that are named for a particular state are referred to herein as "State Trusts." On the Date of Deposit, the Sponsor deposited with the Trustee the aggregate principal amount of bonds indicated in the "Summary of Essential Financial Information". The bonds in a Trust initially consist of delivery statements relating to contracts for their purchase and cash, cash equivalents and/or irrevocable letters of credit issued by a financial institution. Thereafter, the Trustee, in exchange for the bonds in a Trust, delivered to the Sponsor evidence of ownership of the number of Units indicated under "Summary of Essential Financial Information". The bonds in an Intermediate-Term Trust will mature approximately 7 to 13 years from the Date of Deposit. Each Unit initially offered represents a fractional undivided interest in the principal and net income of a Trust. The number of Units is determined based upon a $1,000 principal amount of bonds in the Trust per Unit. To the extent that any Units are redeemed by the Trustee, the fractional undivided interest in a Trust represented by each Unit will increase, although the actual interest in the Trust will remain unchanged. Units will remain outstanding until redeemed by Unitholders or until the termination of the Trust Agreement. Objectives and Bond Selection. The Trusts seek to preserve capital and to provide federal tax-exempt income and, in the case of most State Trusts, Federal and state tax-exempt income taxation. The Trusts invest in portfolios of municipal bonds issued by or on behalf of states and territories of the United States, and political subdivisions and authorities thereof, the interest on which is, in the opinion of recognized bond counsel to the issuing authorities, excludable from gross income for federal and, for State Trusts, state personal income tax purposes under existing law. There is, of course, no guarantee that any Trust will achieve its objectives. A Trust may be an appropriate investment vehicle for investors who desire to participate in a portfolio of tax-exempt fixed income bonds with greater diversification than they might be able to acquire individually. Diversification of a Trust's assets will not eliminate the risk of loss always inherent in the ownership of bonds. Insurance guaranteeing the timely payment, when due, of all principal and interest on the bonds in each Insured Trust has been obtained from municipal bond insurance companies. For information relating to insurance on the bonds, see "Insurance on the Bonds in the Insured Trusts." In selecting bonds for a Trust, the Sponsor considered the following factors, among others: (a) the ratings criteria applicable to your Trust as listed under "Principal Investment Strategy", (b) the prices of the bonds relative to other bonds of comparable quality and maturity, (c) the current income provided by the bonds, (d) the diversification of bonds as to purpose of issue and location of issuer and (e) the probability of early return of principal or high legal or event risk. After the Date of Deposit, a bond may cease to be rated or its rating may be reduced below the minimum required as of the Date of Deposit. Neither event requires elimination of a bond from a Trust but may be considered in the Sponsor's determination as to whether or not to direct the Trustee to dispose of the bond (see "Trust Administration--Portfolio Administration"). The Bonds. Your Trust invests in municipal bonds. States, municipalities and public authorities issue these bonds to raise money for a variety of purposes. In selecting bonds, the Sponsor seeks to diversify your portfolio by type of bond purpose. This section briefly describes different bond types to help you better understand your investment. The types of bonds and percentages they represent in your portfolio are listed under "Summary of Essential Financial Information". These bonds are also described in greater detail in the Information Supplement. General Obligation Bonds and Revenue Bonds. General obligation bonds are backed by the general taxing power of the issuer. The issuer secures these bonds by pledging its faith, credit and unlimited taxing power for the payment of principal and interest. All other bonds in the Trusts are revenue bonds. Revenue bonds are payable only from the revenue of a specific project or authority. They are not supported by the issuer's general power to levy taxes. The risk of default in payment of interest or principal increases if the income of the related project falters because that income is the only source of payment. All of the following bonds are revenue bonds. Airport bonds are obligations of issuers that own and operate airports. The ability of the issuer to make payments on these bonds primarily depends on the ability of airlines to meet their obligations under use agreements. Due to increased competition, deregulation, increased fuel costs and other factors, some airlines may have difficulty meeting these obligations. Bond banks are vehicles that pool various municipal obligations into larger offerings. This reduces the cost of borrowing for the municipalities. The types of financing projects that these obligations support vary. Certificates of participation are generally a type of municipal lease obligation. Lease payments of a governmental entity secure payments on these bonds. These payments depend on the governmental entity budgeting appropriations for the lease payments. A governmental body cannot obligate future governments to appropriate for or make lease payments, but governments typically promise to take action necessary to include lease payments in their budgets. If a government fails to budget for or make lease payments, sufficient funds may not exist to pay interest or principal on these bonds. Health care bonds are obligations of issuers that derive revenue from hospitals and hospital systems. The ability of these issuers to make payments on bonds depends on factors such as facility occupancy levels, demand for services, competition resulting from hospital mergers and affiliations, the need to reduce costs, government regulation, costs of malpractice insurance and claims, and government financial assistance (such as Medicare and Medicaid). Higher education bonds are obligations of issuers that operate universities and colleges. These issuers derive revenues from tuition, dormitories, grants and endowments. These issuers face problems related to declines in the number of college-age individuals, possible inability to raise tuitions and fees, uncertainty of continued federal grants, state funding or donations, and government legislation or regulation. Industrial revenue bonds finance the cost of acquiring, building or improving industrial projects. Private corporations usually operate these projects. The ability of the issuer to make payments on these bonds depends on factors such as the creditworthiness of the corporation operating the project, revenues generated by the project, expenses of the project and environmental or other regulatory restrictions. Multi-family housing bonds are obligations of issuers that derive revenues from mortgage loans on multiple family residences, retirement housing or housing projects for low to moderate-income families. These bonds are generally pre-payable at any time. It is likely that their life will be less than their stated maturity. The ability of these issuers to make payments on bonds depends on such factors as rental income, occupancy levels, operating expenses, mortgage default rates, taxes, government regulations and appropriation of subsidies. Other care bonds include obligations of issuers that derive revenue from mental health facilities, nursing homes and intermediate care facilities. These bonds are similar to health care bonds and the issuers face the same general risks. Public building bonds finance the cost of acquiring, leasing, building or improving public buildings such as offices, recreation facilities, convention centers, police stations, correctional institutions and parking garages. The ability of the issuers to make payments on these bonds depends on factors such as the government budgeting sufficient funds to make lease or mortgage payments on the facility, user fees or rents, costs of maintenance and decreases in use of the facility. Public education bonds are obligations of issuers that operate primary and secondary schools. The ability of these issuers to make payments on these bonds depends primarily on ad valorem taxes. These issuers may also face problems related to litigation contesting state constitutionality of public education financing. Retail electric/gas/telephone bonds are obligations of issuers that derive revenues from the retail sale of utilities to customers. The ability of these issuers to make payments on these bonds depends on factors such as the rates and demand for these utilities, competition, government regulation and rate approvals, overhead expenses and the cost of fuels. Single family housing bonds are obligations of issuers that derive revenues from mortgage loans on single family residences. Single family residences generally include one to four-family dwellings. These bonds are similar to multi-family housing bonds and the issuers face the same general risks. Tax district bonds are obligations secured by a pledge of taxing power by a municipality, such as tax increment financing or tax allocation bonds. These bonds are similar to general obligation bonds. Unlike general obligation bonds, however, the municipality does not pledge its unlimited taxing power to pay these bonds. Instead, the municipality pledges revenues from a specific tax to pay these bonds. If the tax cannot support payment of interest and principal, a municipality may need to raise the related tax to pay these bonds. An inability to raise the tax could have an adverse effect on these bonds. Transportation bonds are obligations of issuers that own and operate public transit systems, ports, highways, turnpikes, bridges and other transportation systems. The ability of these issuers to make payments on these bonds depends on variations in use, the degree of government subsidization, competition from other forms of transportation and increased costs. Port authorities derive revenues primarily from fees imposed on ships using the port facilities. These fees can fluctuate depending on the local economy and competition from air, rail and truck transportation. Increased fuel costs, alternative transportation modes and competition from toll-free bridges and roads will impact revenues of issuers that operate bridges, roads or tunnels. Waste disposal bonds are obligations of issuers that derive revenues from resource recovery facilities. These facilities process solid waste, generate steam and convert steam to electricity. These issuers face problems such as costs and delays due to environmental concerns, effects of conservation and recycling, destruction or condemnation of a project, void or unenforceable contracts, changes in the economic availability of raw materials, operating supplies or facilities, and other unavoidable changes that adversely affect operation of a project. Water and sewer bonds are obligations of issuers that derive revenues from user fees from the sale of water and sewerage services. These issuers face problems such as the ability to obtain rate increases, population declines, difficulties in obtaining new fresh water supplies and "no-growth" zoning ordinances. These issuers also face many of the same problems of waste disposal issuers. Wholesale electric bonds are obligations of issuers that derive revenues from selling electricity to other utilities. The ability of these issuers to make payments on these bonds depends on factors such as the rates and demand for electric utilities, competition, overhead expenses and government regulation and rate approvals. More About the Bonds. In addition to describing the purpose of the bonds, other information about the bonds is also included in the "Portfolio" and notes thereto. This information relates to other characteristics of the bonds. This section briefly describes some of these characteristics. Original issue discount bonds were initially issued at a price below their face (or par) value. These bonds typically pay a lower interest rate than comparable bonds that were issued at or above their par value. In a stable interest rate environment, the market value of these bonds tends to increase more slowly in early years and in greater increments as the bonds approach maturity. The issuers of these bonds may be able to call or redeem a bond before its stated maturity date and at a price less than the bond's par value. Zero coupon bonds are a type of original issue discount bond. These bonds do not pay any current interest during their life. If an investor owns this type of bond, the investor has the right to receive a final payment of the bond's par value at maturity. The price of these bonds often fluctuates greatly during periods of changing market interest rates compared to bonds that make current interest payments. The issuers of these bonds may be able to call or redeem a bond before its stated maturity date and at a price less than the bond's par value. "When, as and if issued" bonds are bonds that trade before they are actually issued. This means that the Sponsor can only deliver them to your Trust "when, as and if" the bonds are actually issued. Delivery of these bonds may be delayed or may not occur. Interest on these bonds does not begin accruing to your Trust until the Sponsor delivers the bond to the Trust. You may have to adjust your tax basis if the Sponsor delivers any of these bonds after the expected delivery date. Any adjustment would reflect interest that accrued between the time you purchased your Units and the delivery of the bonds to your Trust. This could lower your first year estimated current return. You may experience gains or losses on these bonds from the time you purchase Units even though your Trust has not yet received them. In order to acquire certain bonds, it may be necessary for the Sponsor or Trustee to pay amounts covering accrued interest on the bonds which exceed the amounts which will be made available through cash furnished by the Sponsor on the Date of Deposit. This cash may exceed the interest which would accrue to the First Settlement Date. The Trustee has agreed to pay for any amounts necessary to cover any excess and will be reimbursed when funds become available from interest payments on the related bonds. Also, since interest on any "when, as and if issued" bonds does not begin accruing as tax-exempt interest income to the benefit of Unitholders until the date of delivery, the Trustee may reduce its fee and pay Trust expenses in order to maintain or approach the same estimated net annual interest income during the first year of the Trust's operations as described under "Summary of Essential Financial Information". Municipal Bond Risk Factors. All investments involve risk. This section describes the main risks that can impact the value of bonds in your Trust. You should understand these risks before you invest. If the value of the bonds falls, the value of your Units will also fall. You can lose money by investing in a Trust. No one can guarantee that your Trust will achieve its objective or that your investment return will be positive over any period. The Information Supplement contains a more detailed discussion of risks related to your investment. Current economic conditions. The economic recession in the United States which began in 2007 technically came to an end in June of 2009, however the U.S. and global economies continue to feel the effects of this recessionary period, including increased unemployment and below-average levels of economic activity. The U.S. and other foreign governments have taken extraordinary steps to combat the effects of the economic crisis, however the ultimate impact of these measures is unknown and cannot be predicted. In December of 2013, the U.S. Federal Reserve announced it would begin tapering its quantitative easing program, however, there continues to be uncertainty concerning potential future changes to the federal funds rate following a period of near zero interest rates over the previous five years. On August 5, 2011, Standard & Poor's Rating Services downgraded the long-term sovereign credit rating of the United States of America to AA+ from AAA, citing the prolonged controversy over raising the statutory debt ceiling and the related fiscal policy debate. Any substantial change in general market conditions may result in sudden and significant valuation increases or declines in your Trust's holdings. Market risk is the risk that the value of the bonds in your Trust will fluctuate. This could cause the value of your Units to fall below your original purchase price or below the par value. Market value fluctuates in response to various factors. These can include changes in interest rates, inflation, the financial condition of a bond's issuer or insurer, perceptions of the issuer or insurer, or ratings on a bond. Even though the Supervisor supervises your portfolio, you should remember that no one manages your portfolio. Your Trust will not sell a bond solely because the market value falls as is possible in a managed fund. Interest rate risk is the risk that the value of bonds will fall if interest rates increase. Bonds typically fall in value when interest rates rise and rise in value when interest rates fall. Bonds with longer periods before maturity are often more sensitive to interest rate changes. Interest rates in the United States are at or near historic lows, which may increase the Trust's exposure to risks associated with rising interest rates. Credit risk is the risk that a bond's issuer or insurer is unable to meet its obligation to pay principal or interest on the bond. Call risk is the risk that the issuer prepays or "calls" a bond before its stated maturity. An issuer might call a bond if interest rates fall and the bond pays a higher interest rate or if it no longer needs the money for the original purpose. If an issuer calls a bond, your Trust will distribute the principal to you but your future interest distributions will fall. You might not be able to reinvest this principal at as high a yield. A bond's call price could be less than the price your Trust paid for the bond and could be below the bond's par value. This means that you could receive less than the amount you paid for your Units. If enough bonds in your Trust are called, your Trust could terminate early. The first date that the issuer can call each bond is listed under "Portfolio" along with the price the issuer would have to pay. Some or all of the bonds may also be subject to extraordinary optional or mandatory redemptions if certain events occur, such as certain changes in tax laws, the substantial damage or destruction by fire or other casualty of the project for which the proceeds of the bonds were used, and various other events. The call provisions are described in general terms in the "Redemption Feature" column of the "Portfolio" section and the notes thereto. Additional discussion of call provisions appears in the Information Supplement. Bond quality risk is the risk that a bond will fall in value if a rating agency decreases the bond's rating. Bond concentration risk is the risk that your Trust is less diversified because it concentrates in a particular type of bond. When a certain type of bond makes up 25% or more of a Trust, the Trust is considered to be "concentrated" in that bond type. The different bond types are described under "The Bonds". Reduced diversification risk is the risk that your Trust will become smaller and less diversified as bonds are sold, are called or mature. This could increase your risk of loss and increase your share of Trust expenses. Insurer default risk is the risk that an investor of an insured trust could lose income and/or principal if the issuer and the insurer of a municipal bond both default in making their payment obligations. Liquidity risk is the risk that the value of a bond will fall if trading in the bond is limited or absent. No one can guarantee that a liquid trading market will exist for any bond because these bonds generally trade in the over-the-counter market (they are not listed on a securities exchange). Litigation and legislation risk is the risk that future litigation or legislation could affect the value of your Trust. For example, future legislation could reduce tax rates, impose a flat tax, exempt all investment income from tax or change the tax status of the bonds. Litigation could challenge an issuer's authority to issue or make payments on bonds. State Risk Factors. Your Trust may invest significantly in tax-exempt municipal bonds of issuers from a particular state. The financial condition of a state may be affected by various national, economic, social and environmental policies and conditions. Additionally, limitations imposed by constitutional amendments, legislative measures, or voter initiatives on a state and its local governments concerning taxes, bond indebtedness and other matters may constrain the revenue-generating capacity of the state and its local governments and, therefore, the ability of the issuers of the bonds to satisfy their obligations. The economic vitality of a state and its various regions and, therefore, the ability of the state and its local governments to satisfy the bonds, are affected by numerous factors, such as natural disasters, complications with exports and industry deregulation. A state may be a party to numerous lawsuits in which an adverse final decision could materially affect the state's governmental operations and consequently its ability to pay debt service on its obligations. No FDIC Guarantee. An investment in your Trust is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. ESTIMATED CURRENT AND LONG-TERM RETURNS -------------------------------------------------------------------------------- The Estimated Current Return and the Estimated Long-Term Return as of the Date of Deposit are set forth on the cover of the prospectus. Estimated Current Return is calculated by dividing the estimated net annual interest income per Unit by the Public Offering Price. The estimated net annual interest income per Unit will vary with changes in fees and expenses of the Trust and with the principal prepayment, default (if any), redemption, maturity, exchange or sale of bonds. The Public Offering Price will vary with changes in the price of the bonds. Accordingly, there is no assurance that the present Estimated Current Return will be realized in the future. Estimated Long-Term Return is calculated using a formula which (1) takes into consideration, and determines and factors in the relative weightings of, the market values, yields (which takes into account the amortization of premiums and the accretion of discounts) and estimated retirements of the bonds and (2) takes into account the expenses and sales charge associated with Units. Since the value and estimated retirements of the bonds and the expenses of a Trust will change, there is no assurance that the present Estimated Long-Term Return will be realized in the future. The Estimated Current Return and Estimated Long-Term Return are expected to differ because the calculation of Estimated Long-Term Return reflects the estimated dates and amounts of principal returned on the bonds while the Estimated Current Return calculation includes only net annual interest income and Public Offering Price. PUBLIC OFFERING -------------------------------------------------------------------------------- General. Units are offered at the Public Offering Price. During the initial offering period the Public Offering Price is based on the aggregate offering price of the bonds, the sales charge described below, cash, if any, in the Principal Account (including cash to pay organization costs) and accrued interest, if any. Organization costs are not included in the Public Offering Price per Unit for purposes of calculating the sales charge. If you purchase Units during the initial offering period of a Trust with a deferred sales charge, your sales charge will consist of (i) an initial sales charge paid upon the purchase of your Units and (ii) the remaining deferred sales charge, which consists of a fixed dollar amount per Unit paid in installments on specified deferred sales charge payment dates. In no event will your combined initial sales charge and deferred sales charge exceed the maximum percentage sales charge for the applicable Trust as set forth above. For more details, including the specific amount and method of calculation of the initial and deferred sales charge, for those Trusts which offer a deferred sales charge, see the "Fee Table" in prospectus of the applicable Trust. After the initial public offering period, the secondary market Public Offering Price is based on the bid prices of the bonds, the sales charge described below, cash, if any, in the Principal Account and accrued interest, if any. The actual sales charge that may be paid by an investor may differ slightly from the sales charges shown herein due to rounding that occurs in the calculation of the Public Offering Price and in the number of Units purchased. The minimum purchase in the primary and secondary market is one Unit. Certain broker-dealers or selling firms may charge an order handling fee for processing Unit purchases. The maximum initial offering period sales charge for Intermediate-Term Trusts is equal to 3.00% of the Public Offering Price per Unit (3.093% of the aggregate offering price of the bonds). The maximum secondary market sales charge is computed as described in the following table based upon the estimated long-term return life in years ("ELTR Life") of a Trust's portfolio: ELTR Life (Years) Sales Charge -------------------------------- Less than 2 1.50% 2 but less than 4 2.00 4 but less than 6 3.00 6 but less than 8 3.50 8 but less than 11 4.00 11 but less than 15 4.50 15 and over 4.80 The ELTR Life represents the estimated life of the bonds in a Trust's portfolio as determined for purposes of calculating Estimated Long-Term Return. See "Estimated Current and Long-Term Returns". The sales charges in the above table are expressed as a percentage of the secondary market Public Offering Price per Unit. For example, the maximum secondary market sales charge for a Trust with an ELTR Life of "6 but less than 8" years would be 3.50% of the Public Offering Price per Unit (3.630% of the aggregate bid price of the bonds). If you purchase Units in the secondary market of a Trust with a deferred sales charge, your maximum sales charge will be based on the remaining ELTR Life of the Trust as described above and will consist of an initial sales charge and the remaining deferred sales charge, if any. If the secondary market Units are purchased prior to the final deferred sales charge payment date, the initial sales charge, which you pay at the time of purchase, is the difference between the secondary market sales charge based on the ELTR Life listed above and the maximum remaining deferred sales charge. If you purchase Units after the last deferred sales charge payment has been assessed, your maximum sales charge will consist of the one time initial sales charge based on the ELTR Life. Reducing Your Sales Charge. The Sponsor offers a variety of ways for you to reduce the sales charge that you pay. It is your financial professional's responsibility to alert the Sponsor of any discount when you purchase Units. Before you purchase Units you must also inform your broker-dealer of your qualification for any discount or of any combined purchases to be eligible for a reduced sales charge. As further described in this section, purchases executed on the same day by a single person at the same broker-dealer may be combined for sales charge discount calculation purposes. Secondary market purchases are excluded for purposes of sales charge discount calculations. For Trusts with a deferred sales charge, these charges are fixed dollar amounts per Unit, and your Trust must charge these amounts per Unit regardless of any discounts. However, if you are eligible to receive a discount such that your total sales charge is less than the fixed dollar amounts of the deferred sales charges, you will receive a credit equal to the difference between your total sales charge and these fixed dollar charges at the time you buy Units. Large Quantity Purchases. You can reduce your sales charge by increasing the size of your investment. Based upon the aggregate dollar amount of Units purchased by a Unitholder in the initial offering period, the following table shows both the corresponding sales charge and the concession or agency commission allowed to broker-dealers and other selling agents on such transaction. Broker-Dealer Sales Charge for Concession or Intermediate-Term Agency Transaction Amount Trusts Commission ---------------------------------------------------------- Less than $100,000 3.00% 2.10% $100,000 - $249,999 2.60 1.80 $250,000 - $499,999 2.40 1.70 $500,000 - $999,999 2.20 1.50 $1,000,000 - $2,999,999 2.00 1.30 $3,000,000 - $4,999,999 1.70 1.10 $5,000,000 or more 1.50 0.90 Except as described below, these quantity discount levels apply only to purchases of a single Trust made by the same person on a single day from a single broker-dealer. Additional information regarding the broker-dealer concession or agency commission is presented in the "Unit Distribution" section. Aggregated Purchases--For purposes of achieving these levels, you may combine certain purchases made on the same day through a single broker-dealer or selling agent, as further described below. You must inform your broker-dealer of any combined purchases before your purchase to be eligible for a reduced sales charge. For purposes of achieving the quantity discount levels in the above table, Units of a Trust offered in this prospectus may be combined with (i) purchases of units of any other Invesco-sponsored unit investment trusts during each trust's initial offering period, (ii) purchases of units made as described under the "Fee Accounts" paragraph in this section, and (iii) purchases of units eligible for the sales charge discounts described under the "Exchanges" paragraph in this section. In addition, Units purchased in the name of your spouse (or the equivalent if recognized under local law) or children (including step-children) under 21 living in the same household as you will be deemed to be additional purchases by you for the purposes of calculating the applicable quantity discount level. The reduced sales charge levels will also be applicable to a trustee or other fiduciary purchasing Units for a single trust, estate (including multiple trusts created under a single estate) or fiduciary account. Fee Accounts. A portion of the sales charge is waived for certain accounts described in this paragraph. Purchases by these accounts are subject only to the portion of the sales charge that is retained by the Sponsor. Please refer to the section called "Fee Accounts" for additional information on these purchases. Units may be purchased in the initial offering period at the Public Offering Price less the maximum applicable concession the Sponsor typically allows to brokers and dealers (either non-Underwriter or Underwriter concession, whichever is greater) for purchases by investors who purchase Units through registered investment advisers, certified financial planners and registered broker-dealers who in each case either charge periodic fees for brokerage services, financial planning, investment advisory or asset management services, or provide such services in connection with the establishment of an investment account for which a comprehensive "wrap fee" charge ("Wrap Fee") is imposed ("Fee Accounts") if the Units are purchased for a Fee Account and the Trust is subject to a Wrap Fee (i.e. the Trust is "Wrap Fee Eligible"). For example, with respect to an Intermediate-Term Trust, Wrap Fee Eligible purchasers would pay a sales charge of only 0.65%, which represents the maximum sales charge of 3.00% minus the maximum applicable concession of 2.35%. The Sponsor reserves the right to limit or deny purchases of Units described in this paragraph by investors or selling firms whose frequent trading activity is determined to be detrimental to a Trust. As described above in "Large Quantity Purchases", Units purchased for a Fee Account may be combined with certain other purchases for purposes of achieving the quantity discount levels presented in the table above under "Large Quantity Purchases", however, such Wrap Fee Eligible Units are not eligible for any sales charge discounts in addition to that which is described in this paragraph and under the "Fee Accounts" section found below. Exchanges. During the initial offering period of a Trust, unitholders of any Invesco-sponsored unit investment trust and unitholders of unaffiliated unit investment trusts may utilize their redemption or termination proceeds from such trusts to purchase Units of an Intermediate-Term Trust, or units of any other Invesco-sponsored unit investment trust in its initial offering period, at a reduced sales charge. For such purchases of less than $3,000,000, the sales charge will be reduced by 1.00% for Units of an Intermediate-Term Trust. For purchases of $3,000,000 or more, either made solely with redemption or termination proceeds from other unit investment trusts or in combination with other purchases as described above under "Large Quantity Purchases", Intermediate-Term Trust Units will be eligible for the applicable quantity discount level presented in the table that appears in that subsection. For aggregated purchases described above in the "Large Quantity Purchases" subsection that consist of any units other than Intermediate-Term Trust Units, please refer to the prospectus of the applicable Invesco-sponsored unit investment trust for information regarding the specified sales charge reductions on those units. In order to be eligible for the sales charge discounts applicable to Unit purchases made with redemption or termination proceeds from other unit investment trusts, the trade date of each rollover or redemption, or each other trust's termination date resulting in the receipt of such proceeds used to purchase Units of the Trust must all be derived from transactions that occurred within 30 calendar days prior to your Unit purchase. In addition, the discounts will only be available for investors that utilize the same broker-dealer (or a different broker-dealer with appropriate notification) for both the Unit purchase and the transaction resulting in the receipt of the termination or redemption proceeds used for the Unit purchase. You may be required to provide appropriate documentation or other information to your broker-dealer to evidence your eligibility for these reduced sales charge discounts. An exchange does not avoid a taxable event on the redemption or termination of an interest in a Trust. Employees. Employees, officers and directors (including their spouses (or the equivalent if recognized under local law) and children or step-children under 21 living in the same household, parents or step-parents and trustees, custodians or fiduciaries for the benefit of such persons (collectively referred to herein as "related purchasers")) of Invesco Capital Markets, Inc. and its affiliates and, when permitted, Underwriters and their affiliates may purchase Units at the Public Offering Price less the applicable underwriting commission or less the applicable dealer concession in the absence of an underwriting commission. Employees, officers and directors (including related purchasers) of dealers and their affiliates may purchase Units at the Public Offering Price less the applicable dealer concession. All employee discounts are subject to the policies of the related selling firm. Only employees, officers and directors of companies that allow their employees to participate in this employee discount program are eligible for the discounts. Unit Price. The Public Offering Price of Units will vary from the amounts stated under "Summary of Essential Financial Information" in accordance with fluctuations in the prices of the bonds. The price of Units as of the opening of business on the Date of Deposit was determined by adding the applicable sales charge and organization costs to the aggregate offering price of the bonds and dividing the sum by the number of Units outstanding. This price determination was made on the basis of an evaluation of the bonds prepared by the Evaluator. During the initial offering period, the Evaluator will value the bonds as of the Evaluation Time on days the New York Stock Exchange is open for business and will adjust the Public Offering Price of Units accordingly. The "Evaluation Time" is the close of trading on the New York Stock Exchange on each day that the Exchange is open for regular trading, or earlier on days where the Bond Market Association recommends an early bond market close, provided, however, on the Date of Deposit the "Evaluation Time" will be the close of regular trading on the New York Stock Exchange or the time the registration statement filed with the Securities and Exchange Commission (the "SEC") becomes effective, if later. The secondary market Public Offering Price per Unit will be equal to the aggregate bid price of the bonds plus the applicable secondary market sales charge and dividing the sum by the number of Units outstanding. For secondary market purposes, this computation will be made by the Evaluator as of the Evaluation Time for each day on which any Unit is tendered for redemption and as necessary. The offering price of bonds may be expected to range approximately from 0.125% to 1.375% more than the bid price. The Public Offering Price per Unit will be effective for all orders received prior to the Evaluation Time on each business day. Orders received by the Sponsor prior to the Evaluation Time and orders received by authorized financial professionals prior to the Evaluation Time that are properly transmitted to the Sponsor by the time designated by the Sponsor, are priced based on the date of receipt. Orders received by the Sponsor after the Evaluation Time, and orders received by authorized financial professionals after the Evaluation Time or orders received by such persons that are not transmitted to the Sponsor until after the time designated by the Sponsor, are priced based on the date of the next determined Public Offering Price per Unit provided they are received timely by the Sponsor on such date. It is the responsibility of authorized financial professionals to transmit orders received by them to the Sponsor so they will be received in a timely manner. The aggregate price of the bonds is determined on the basis of bid prices or offering prices, as is appropriate, (a) on the basis of current market prices obtained from dealers or brokers who customarily deal in bonds comparable to those held by the Trusts; (b) if these prices are not available, on the basis of current market prices for comparable bonds; (c) by causing the value of the bonds to be determined by others engaged in the practice of evaluation, quoting or appraising comparable bonds; or (d) by any combination of the above. Market prices of the bonds will generally fluctuate with changes in market interest rates. A person will become the owner of Units on the date of settlement provided payment has been received. Cash, if any, made available to the Sponsor prior to the date of settlement for the purchase of Units may be used in the Sponsor's business and may be deemed to be a benefit to the Sponsor, subject to the limitations of the Securities Exchange Act of 1934. Organization Costs. During the initial offering period, part of the Public Offering Price represents an amount of cash deposited to pay the estimated costs incurred in establishing your Trust. These costs include the costs of preparing documents relating to the Trust (such as the registration statement, prospectus, trust agreement and legal documents), federal and state registration fees, the initial fees and expenses of the Trustee and the initial audit. Your Trust will reimburse us for these costs at the end of the initial offering period or after six months, if earlier. The value of your Units will decline when the Trust deducts these costs from the Trust assets. Accrued Interest. Accrued interest is an accumulation of unpaid interest on securities which generally is paid by the bonds semi-annually, although each Trust accrues interest daily. Because of this, a Trust always has an amount of interest earned but not yet collected by the Trustee. For this reason, with respect to sales settling after the First Settlement Date, the proportionate share of accrued interest to the settlement date is added to the Public Offering Price of Units. You will receive the amount of accrued interest paid on your Units on the next distribution date. In an effort to reduce the accrued interest which would have to be paid by Unitholders, the Trustee will advance the amount of accrued interest to the Sponsor as the Unitholder of record as of the First Settlement Date. Consequently, the accrued interest added to the Public Offering Price of Units will include only accrued interest from the First Settlement Date to the date of settlement, less any distributions from the Interest Account after the First Settlement Date. Because of the varying interest payment dates of the bonds, accrued interest at any point in time will be greater than the amount of interest actually received by a Trust and distributed to Unitholders. If you sell or redeem all or a portion of your Units, you will be entitled to receive your proportionate share of the accrued interest from the purchaser of your Units. Unit Distribution. Units will be distributed to the public by Underwriters, broker-dealers and others at the Public Offering Price, plus accrued interest. The Sponsor intends to qualify Units for sale in a number of states. Intermediate-Term Trust Concessions. During the initial offering period, the Sponsor and Underwriters will sell Units of Intermediate-Term Trusts to non-Underwriter broker-dealers and selling agents at the Public Offering Price (net of any sales charge discount) less the applicable gross concession or agency commission set forth in the "Broker-Dealer Concession or Agency Commission" column of the table under "Reducing Your Sales Charge -- Large Quantity Purchases". These breakpoints will be adjusted to take into consideration purchase orders stated in dollars which cannot be completely fulfilled due to the requirement that only whole Units be issued. For initial offering period transactions involving unitholders of other unit investment trusts who use their redemption or termination proceeds to purchase Units of an Intermediate-Term Trust, the regular concession or agency commission allowed by the Sponsor to broker-dealers and other selling agents will amount to 1.30% for aggregated purchases of less than $3,000,000. For such aggregated purchases of $3,000,000 or more, the regular concession or agency commission will correspond to the amounts listed in the "Broker-Dealer Concession or Agency Commission" column of the table under "Reducing Your Sales Charge -- Large Quantity Purchases". Underwriters other than the Sponsor will sell Units to other broker-dealers and selling agents at the Public Offering Price less a concession or agency commission not in excess of the maximum concession allowed to Underwriters by the Sponsor as described under "Sponsor and Underwriter Compensation" below. Following the end of the initial offering period, any broker-dealer or other selling agent who is not a Qualifying Broker-Dealer (as described below) will be entitled to receive an additional per Unit concession based on the following table corresponding to the aggregate number of Trust Units purchased from the Sponsor as of the end of the initial offering period. Aggregate Number of Units Additional Purchased from the Sponsor Concession -------------------------------------- 250 - 999 Units 0.10% 1,000 Units - 2,999 Units 0.20% 3,000 Units or more 0.25% Notwithstanding the concession amounts presented in the "Broker-Dealer Concession or Agency Commission" column of the table under "Reducing Your Sales Charge -- Large Quantity Purchases", broker-dealers and other selling agents who have not acted as Underwriters for the Trust that purchase 250 or more Units of a Trust from the Sponsor on the Date of Deposit ("Qualifying Broker-Dealers") will be allowed a concession or agency commission on all Units of a Trust purchased from the Sponsor throughout the initial offering period equal to the regular concession allowed to Underwriters described under "Sponsor and Underwriter Compensation" below. Further, Qualifying Broker-Dealers not receiving the maximum concession amount per Unit on the Date of Deposit may be eligible to receive an additional per Unit concession based upon the aggregate number of Trust Units purchased from the Sponsor as of the end of the initial offering period. Qualifying Broker Dealers having purchased less than 1,000 Units of the Trust from the Sponsor on the Date of Deposit will be entitled to an additional concession of 0.10% if the aggregate number of Trust Units purchased from the Sponsor as of the end of the initial offering period totals at least 1,000 Units but less than 3,000 Units, or an additional concession of 0.15% for totals of at least 3,000 Units. Qualifying Broker Dealers having purchased at least 1,000 Units but less than 3,000 Units of the Trust from the Sponsor on the Date of Deposit will be entitled to an additional concession of 0.05% if the aggregate number of Trust Units purchased from the Sponsor as of the end of the initial offering period totals at least 3,000 Units. Regarding the additional per Unit concessions described above for both Qualifying Broker Dealers and for other broker-dealers or selling agents, these additional concessions will also be applied on a dollar basis utilizing an equivalent of $1,000 per Unit and will be applied on whichever basis is more favorable to the dealer firm or selling agent. Purchase orders stated in dollars which cannot be completely fulfilled due to the requirement that only whole Units be issued will be subject to the concession amount corresponding to the dollar amount of the purchase order, utilizing a $1,000 per Unit equivalent. Concessions Based Upon Annual Sales. As described below, broker-dealers and other selling agents may in certain cases be eligible for additional concessions based upon their annual eligible sales of all Invesco fixed income and equity unit investment trusts. Eligible sales include all units of any Invesco unit investment trust underwritten or purchased directly from Invesco during a trust's initial offering period. For purposes of the Volume Concession described below, trusts designated as either "Invesco Unit Trusts, Taxable Income Series" or "Invesco Unit Trusts, Municipal Series" are fixed income trusts, and trusts designated as "Invesco Unit Trusts Series" are equity trusts. Volume Concession--In addition to the concessions or agency commissions described above, all broker-dealers and other selling firms (including Underwriters) will be eligible to receive additional compensation based on total initial offering period sales of all eligible Invesco unit investment trusts during the previous consecutive 12-month period through the end of the most recent month. The Volume Concession, as applicable to equity and fixed income trust units, is set forth in the following table: Volume Concession ------------------------- Total Sales Equity Trust Fixed Income (in millions) Units Trust Units ------------------------------------------------------- $25 but less than $100 0.050% 0.050% $100 but less than $150 0.075 0.075 $150 but less than $250 0.100 0.100 $250 but less than $500 0.115 0.100 $500 but less than $750 0.125 0.100 $750 but less than $1,000 0.130 0.100 $1,000 but less than $1,500 0.135 0.100 $1,500 but less than $2,000 0.140 0.100 $2,000 but less than $3,000 0.150 0.100 $3,000 but less than $4,000 0.160 0.100 $4,000 but less than $5,000 0.170 0.100 $5,000 or more 0.175 0.100 Broker-dealers and other selling firms will not receive the Volume Concession on the sale of units purchased in Fee Accounts, however, such sales will be included in determining whether a firm has met the sales level breakpoints set forth in the Volume Concession table above. Secondary market sales of all unit investment trusts are excluded for purposes of the Volume Concession. Eligible dealer firms and other selling agents include clearing firms that place orders with Invesco and provide Invesco with information with respect to the representatives who initiated such transactions. Eligible dealer firms and other selling agents will not include firms that solely provide clearing services to other broker-dealer firms or firms who place orders through clearing firms that are eligible dealers. We reserve the right to change the amount of the concessions or agency commissions from time to time. For a trust to be eligible for this additional compensation, the trust's prospectus must include disclosure related to this additional compensation. Additional Volume Concession Eligibility -- Underwriters, broker-dealers or other selling firms having achieved $500 million in total eligible sales for the previous 12 month period through the end of the most recent month are eligible to receive an additional volume concession for each Trust Unit underwritten or purchased directly from the Sponsor on the Initial Date of Deposit equal to the difference between the maximum allowable concession described under "Sponsor and Underwriter Compensation" and the per Unit concession applicable to each Trust Unit underwritten or purchased. Only Units acquired on the Date of Deposit may qualify for this additional per Unit volume concession, and Unit acquisitions made on subsequent days will be subject to the applicable levels as stated in the "Unit Distribution" and "Sponsor and Underwriter Compensation" sections. This additional per Unit volume concession will be payable either at the time the Units are acquired or following the end of the initial offering period, at the election of the recipient. With respect to any Units for which an Underwriter, broker-dealer or other selling firm receives this additional per Unit volume concession, such Units will not be eligible for additional per Unit concessions described under "Intermediate-Term Trust Concessions." Additional Information. Certain commercial banks may be making Units available to their customers on an agency basis. A portion of the sales charge paid by these customers (equal to the agency commission referred to above) is retained by or remitted to the banks. Any discount provided to investors will be borne by the selling dealer or agent. For secondary market transactions, the Sponsor will sell Units to broker-dealers and selling agents at the Public Offering Price less a concession or agency commission of 80% of the applicable sales charge. Dealers other than the Sponsor may sell Units in the secondary market to other broker-dealers and selling agents at the Public Offering Price less a concession or agency commission not in excess of the secondary market concession allowed to the dealer. Notwithstanding anything to the contrary herein, in no case shall the total of any concessions, agency commissions and any additional compensation allowed or paid to any broker, dealer or other distributor of Units with respect to any individual transaction exceed the maximum sales charge applicable to Intermediate-Term Trusts. The Sponsor reserves the right to reject, in whole or in part, any order for the purchase of Units and to change the amount of the concession or agency commission to dealers and others from time to time. Sponsor and Underwriter Compensation. The Sponsor will sell Units to Underwriters at the regular Public Offering Price per Unit less a gross concession described in the sections below. For a list of the Underwriters that have purchased Units from the Sponsor, see "Underwriting". The Sponsor will sell Units of Intermediate-Term Trusts to Underwriters at the regular Public Offering Price per Unit less the concession per Unit underwritten set forth in the following table. Underwriter Units Concession ------------------------------------- 250 - 999 Units 2.20% 1,000 Units - 2,999 Units 2.30% 3,000 Units or more 2.35% An Underwriter will be allowed a concession throughout the initial offering period of a Trust equal to the Underwriter concession allowed to such firm on the Date of Deposit for Units subsequently purchased from the Sponsor. At the end of the initial offering period, an Underwriter not receiving the maximum concession amount per Unit on the Date of Deposit may be eligible to receive an additional per Unit concession based upon the aggregate number of Trust Units underwritten and subsequently purchased from the Sponsor as of the end of the initial offering period. Underwriters having underwritten less than 1,000 Units of the Trust will be entitled to an additional concession of 0.10% if the aggregate number of Trust Units underwritten and subsequently purchased from the Sponsor as of the end of the initial offering period totals at least 1,000 Units but less than 3,000 Units, or an additional concession of 0.15% for totals of at least 3,000 Units. Underwriters having underwritten at least 1,000 Units but less than 3,000 Units of the Trust will be entitled to an additional concession of 0.05% if the aggregate number of Trust Units underwritten and subsequently purchased from the Sponsor as of the end of the initial offering period totals at least 3,000 Units. The concessions for a) Units underwritten on the Date of Deposit, b) Units purchased from the Sponsor by an Underwriter subsequent to the Date of Deposit during a Trust's initial offering period, and c) the additional per Unit concession for Underwriters will each also be applied on a dollar basis utilizing an equivalent of $1,000 per Unit and will be applied on whichever basis is more favorable to the Underwriter. Purchase orders stated in dollars which cannot be completely fulfilled due to the requirement that only whole Units be issued will be subject to the concession amount corresponding to the stated dollar amount of the purchase order, utilizing a $1,000 per Unit equivalent. Any Underwriter which has achieved $500 million in total eligible sales for the previous 12 month period through the end of the most recent month will be eligible to receive an additional per Unit volume concession as described under "Unit Distribution--Concessions Based Upon Annual Sales--Additional Volume Concession Eligibility". In connection with Underwriter sales of Units to non-Underwriter broker-dealers and other selling agents which Units in turn are sold to investors in sufficient size to qualify for quantity discounts, in certain instances, the sum of the sales charge discount and the broker-dealer concession may exceed the concession allowed to the Underwriter. At the request of the Underwriter, the Sponsor may repurchase such Units at the Public Offering Price per Unit less the concession amount allowed to the Underwriter during the Trust's initial offering period, and subsequently resell those Units back to the Underwriter at the Public Offering Price per Unit less the applicable sales charge reduction per Unit and broker-dealer concession amounts listed in the table found under "Public Offering--Reducing Your Sales Charge--Large Quantity Purchases". In addition, the Sponsor and certain Underwriters will realize a profit or loss, as a result of the difference between the price paid for the bonds by the Sponsor and the cost of the bonds to a Trust. See "Portfolio" and "Notes to Portfolio". The Sponsor and the Underwriters may also realize profits or losses with respect to bonds which were acquired by the Sponsor from underwriting syndicates of which they were members. The Sponsor has not participated as sole underwriter or as manager or as a member of the underwriting syndicates from which the bonds were acquired. Underwriters may further realize profit or loss during the initial offering period as a result of possible fluctuations in the market value of the bonds since all proceeds received from purchasers of Units (excluding dealer concessions or agency commissions allowed, if any) will be retained by the Underwriters. Affiliates of an Underwriter are entitled to the same dealer concessions or agency commissions that are available to the Underwriter. In addition to any other benefits Underwriters may realize from the sale of Units, the Sponsor will share with certain Underwriters a portion of any gain represented by the difference between the cost of the bonds to the Sponsor and the evaluation of the bonds on the Date of Deposit (less deductions for accrued interest and certain costs). For Underwriters who either (a) underwrite at least 3,000 Units or (b) submit an Underwriter purchase order of at least $3,000,000, the Sponsor will share 50% of that portion of the gain that relates to the Units actually underwritten by such Underwriters. For those Underwriters who either (a) underwrite at least 1,000 Units but less than 3,000 Units or (b) submit an Underwriter purchase order of at least $1,000,000 but less than $3,000,000, the Sponsor will share 25% of that portion of the gain that relates to the Units actually underwritten by such Underwriters. The Sponsor and certain of the other Underwriters will also realize profits or losses in the amount of any difference between the price at which Units are purchased and the price at which Units are resold in connection with maintaining a secondary market for Units and will also realize profits or losses resulting from a redemption of repurchased Units at a price above or below the purchase price. We may provide, at our own expense and out of our own profits, additional compensation and benefits to broker-dealers who sell Units of Trusts and our other products. This compensation is intended to result in additional sales of our products and/or compensate broker-dealers and financial advisers for past sales. We may make these payments for marketing, promotional or related expenses, including, but not limited to, expenses of entertaining retail customers and financial advisers, advertising, sponsorship of events or seminars, obtaining shelf space in broker-dealer firms and similar activities designed to promote the sale of Trusts and our other products. Fees may include payment for travel expenses, including lodging, incurred in connection with trips taken by invited registered representatives for meetings or seminars of a business nature. These arrangements will not change the price you pay for your Units. Market for Units. Although not obligated to do so, the Sponsor intends to, and certain of the other Underwriters may, maintain a market for Units and offer to purchase Units at prices, subject to change at any time, based upon the aggregate bid prices of the bonds plus accrued interest and any principal cash on hand, less any amounts representing taxes or other governmental charges payable out of the Trust and less any accrued Trust expenses. If the supply of Units exceeds demand or if some other business reason warrants it, the Sponsor and/or the Underwriters may either discontinue all purchases of Units or discontinue purchases of Units at these prices. If a market is not maintained and the Unitholder cannot find another purchaser, a Unitholder will be able to dispose of Units by tendering them to the Trustee for redemption at the Redemption Price. See "Rights of Unitholders--Redemption of Units". A Unitholder who wishes to dispose of his Units should inquire of his broker as to current market prices in order to determine whether there is any price in excess of the Redemption Price and, if so, the amount thereof. With respect to Units of Trusts with a deferred sales charge, any such Units sold prior to the time the entire deferred sales charge has been collected will be assessed the amount of any remaining deferred sales charge at the time of sale. The Trustee will notify the Sponsor of any tender of Units for redemption. If the Sponsor's bid in the secondary market at that time equals or exceeds the Redemption Price per Unit, it may purchase the Units not later than the day on which the Units would otherwise have been redeemed by the Trustee. FEE ACCOUNTS -------------------------------------------------------------------------------- As described above, Units may be available for purchase by investors in Fee Accounts where the Trust is Wrap Fee Eligible. You should consult your financial professional to determine whether you can benefit from these accounts. For these purchases you generally only pay the portion of the sales charge that is retained by your Trust's Sponsor, Invesco Capital Markets, Inc. You should consult the "Public Offering--Reducing Your Sales Charge" section for specific information on this and other sales charge discounts. That section governs the calculation of all sales charge discounts. The Sponsor reserves the right to limit or deny purchases of Units in Fee Accounts by investors or selling firms whose frequent trading activity is determined to be detrimental to a Trust. RIGHTS OF UNITHOLDERS -------------------------------------------------------------------------------- Distributions of Interest and Principal. Interest received by a Trust, pro rated on an annual basis, will be distributed monthly. The amount and time of the first distribution is described under "Summary of Essential Financial Information." In addition, a Trust that has elected to be structured as a "regulated investment company" for federal tax purposes may make additional required distributions at the end of each year. Interest received by a Trust, including that part of the proceeds of any disposition of bonds which represents accrued interest, is credited by the Trustee to the Interest Account. Other receipts are credited to the Principal Account. After deduction of amounts sufficient to reimburse the Trustee, without interest, for any amounts advanced and paid to the Sponsor as the Unitholder of record as of the First Settlement Date, interest received will be distributed on each distribution date to Unitholders of record as of the preceding record date. All distributions will be net of estimated expenses. The Trustee is not required to pay interest on funds held in the Principal or Interest Account (but may itself earn interest thereon and therefore benefits from the use of these funds). Should the amount available for distribution in the Principal Account equal or exceed $5.00 per Unit, the Trustee will make a distribution from the Principal Account on the next monthly distribution date to Unitholders of record on the related monthly record date. However, funds in the Principal Account will be distributed on the last distribution date of each calendar year to Unitholders of record as of the preceding record date if the amount available for distribution shall equal at least $1.00 per Unit. Because interest payments are not received by a Trust at a constant rate throughout the year, interest distributions may be more or less than the amount credited to the Interest Account as of the record date. For the purpose of minimizing fluctuations in interest distributions, the Trustee is authorized to advance amounts necessary to provide interest distributions of approximately equal amounts. The Trustee is reimbursed for these advances from funds in the Interest Account on the next record date. Persons who purchase Units between a record date and a distribution date will receive their first distribution on the second distribution date after the purchase. Redemption of Units. All or a portion of your Units may be tendered to The Bank of New York Mellon, the Trustee, for redemption at Unit Investment Trust Division, 111 Sanders Creek Parkway, East Syracuse, New York 13057, on any day the New York Stock Exchange is open. No redemption fee will be charged by the Sponsor or the Trustee, but you are responsible for applicable governmental charges, if any. Units redeemed by the Trustee will be canceled. You may redeem all or a portion of your Units by sending a request for redemption to your bank or broker-dealer through which you hold your Units. No later than three business days following satisfactory tender, the Unitholder will receive an amount for each Unit equal to the Redemption Price per Unit next computed after receipt by the Trustee of the tender of Units. The "date of tender" is deemed to be the date on which Units are received by the Trustee, except that as regards Units received after the Evaluation Time on days of trading on the New York Stock Exchange, the date of tender is the next day on which that Exchange is open and the Units will be deemed to have been tendered to the Trustee on that day for redemption at the Redemption Price. Redemption requests received by authorized financial professionals prior to the Evaluation Time that are properly transmitted to the Trustee by the time designated by the Trustee, are priced based on the date of receipt. Redemption requests received by the Trustee after the Evaluation Time, and redemption requests received by authorized financial professionals after the Evaluation Time or redemption requests received by such persons that are not transmitted to the Trustee until after the time designated by the Trustee, are priced based on the date of the next determined redemption price provided they are received timely by the Trustee on such date. It is the responsibility of authorized financial professionals to transmit redemption requests received by them to the Trustee so they will be received in a timely manner. Certain broker-dealers or selling firms may charge an order handling fee for processing redemption requests. Units redeemed directly through the Trustee are not subject to such fees. Under Internal Revenue Service regulations, the Trustee is required to withhold a specified percentage of a Unit redemption if the Trustee has not received the Unitholder's tax identification number as required by such regulations. Any amount withheld is transmitted to the Internal Revenue Service and may be recovered by the Unitholder only when filing a return. Under normal circumstances the Trustee obtains the Unitholder's tax identification number from the selling broker. However, at any time a Unitholder elects to tender Units for redemption, the Unitholder should provide a tax identification number to the Trustee in order to avoid this possible "back-up withholding." The Redemption Price per Unit (as well as the secondary market Public Offering Price) will be determined on the basis of the bid price of the bonds as of the Evaluation Time on days of trading on the New York Stock Exchange on the date any such determination is made. The Evaluator determines the Redemption Price per Unit on days Units are tendered for redemption. The Redemption Price per Unit is the pro rata share of each Unit on the basis of (i) the cash on hand in the Trust or moneys in the process of being collected, (ii) the value of the bonds based on the bid prices of the bonds, (iii) accrued interest, less (a) amounts representing taxes or other governmental charges, (b) the accrued Trust expenses and (c) for Trusts with a deferred sales charge, any unpaid deferred sales charge payments. During the initial offering period, the Redemption Price and secondary market repurchase price are not reduced by estimated organization costs. The Evaluator may determine the value of the bonds by employing any of the methods set forth in "Public Offering--Unit Price." Accrued interest paid on redemption shall be withdrawn from the Interest Account or, if the balance therein is insufficient, from the Principal Account. All other amounts will be withdrawn from the Principal Account. Units so redeemed shall be cancelled. The price at which Units may be redeemed could be less than the price paid by the Unitholder and may be less than the par value of the bonds represented by the Units redeemed. The Trustee may sell bonds to cover redemptions. When bonds are sold, the size and diversity of the Trust will be reduced. Sales may be required at a time when bonds would not otherwise be sold and might result in lower prices than might otherwise be realized. The Trustee reserves the right to satisfy any redemption of 1,000 or more Units with an aggregate redemption price of $1,000,000 or more in an in kind distribution of bonds. An in kind distribution of bonds will be made by the Trustee through the distribution of each of the bonds in the Trust in book-entry form to the account of the Unitholder's broker-dealer at Depository Trust Company. Amounts representing fractional portions of a bond will be distributed in cash. The Trustee may adjust the bonds included in a Unitholder's in kind distribution to facilitate the distribution of whole bonds. Special tax consequences will result if a Unitholder receives an in kind distribution. The right of redemption may be suspended and payment postponed for any period during which the New York Stock Exchange is closed, other than for customary weekend and holiday closings, or during which the SEC determines that trading on that Exchange is restricted or an emergency exists, as a result of which disposal or evaluation of the bonds is not reasonably practicable, or for other periods as the SEC may by order permit. Under certain extreme circumstances the Sponsor may apply to the SEC for an order permitting a full or partial suspension of the right of Unitholders to redeem their Units. Exchange Option. When you redeem Units of your Trust or when your Trust terminates, you may be able to exchange your Units for units of other Invesco unit trusts at a reduced sales charge. An exchange does not avoid a taxable disposition of your redeemed Units. You should contact your financial professional for more information about trusts currently available for exchanges. Before you exchange Units, you should read the prospectus of the new trust carefully and understand the risks and fees. You should then discuss this option with your financial professional to determine whether your investment goals have changed, whether current trusts suit you and to discuss tax consequences. We may discontinue this option at any time. The exchange will generally be treated as a sale and a taxable transaction for federal and state income tax purposes. Units. Ownership of Units is evidenced in book-entry form only and will not be evidenced by certificates. Units purchased or held through your bank or broker-dealer will be recorded in book-entry form and credited to the account of your bank or broker-dealer at the Depository Trust Company ("DTC"). Units are transferable by contacting your bank or broker-dealer through which you hold your Units. Transfer, and the requirements therefore, will be governed by the applicable procedures of DTC and your agreement with the DTC participant in whose name your Units are registered on the transfer records of DTC. Reports Provided. Unitholders will receive a statement of interest and other receipts received for each distribution. For as long as the Sponsor deems it to be in the best interest of Unitholders, the accounts of each Trust will be audited annually by an independent registered public accounting firm and the report of the accountants will be furnished to Unitholders upon request. Within a reasonable period of time after the end of each year, the Trustee will furnish to each person who was a registered Unitholder during that year a statement describing the interest and principal received on the bonds, actual Trust distributions, Trust expenses, a list of the bonds and other Trust information. Unitholders will be furnished the Evaluator's evaluations of the bonds upon request to the Trustee. If you have questions regarding your account or your Trust, please contact your financial advisor or the Trustee. The Sponsor does not have access to individual account information. INSURANCE ON THE BONDS -------------------------------------------------------------------------------- Insurance may have been obtained guaranteeing prompt payment of interest and principal, when due, in respect of certain of the bonds in your Trust. The premium for any preinsured bond insurance has been paid by the issuer, by a prior owner of the bonds and any policy is non-cancelable and will continue in force so long as the bonds so insured are outstanding and the preinsured bond insurer remains in business. The preinsured bond insurers are described in "Portfolio" and the notes thereto. More detailed information regarding insurance on the bonds and the preinsured bond insurers is included in the Information Supplement. See "Additional Information." Each insurer is subject to regulation by the department of insurance in the state in which it is qualified to do business. Such regulation, however, is no guarantee that each insurer will be able to perform on its contract of insurance in the event a claim should be made. The financial information with respect to each insurer appears in reports filed with state insurance regulatory authorities and is subject to audit and review by such authorities. No representation is made herein as to the accuracy or adequacy of such information or as to the absence of material adverse changes in such information subsequent to the dates thereof. Bond Insurers. Any downgrade in the rating of an insurer of the bonds in the Trust may result in a downgrade in the rating of the issuer of the related bond and therefore may have a material adverse effect on the value of the bonds in the Trust and the value of your Units. The following is a description of the various bond insurers: ACA Financial Guaranty Corporation ("ACA Financial Guaranty"). On December 15, 2008, S&P withdrew the financial strength, financial enhancement, and issuer credit ratings of ACA Financial Guaranty. Ambac Assurance Corporation ("Ambac"). On November 8, 2010, Ambac Financial Group, Inc., the holding company of Ambac, announced that it has filed for a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the Southern District of New York (the "Bankruptcy Court"). Ambac Financial Group, Inc. will continue to operate in the ordinary course of business as "debtor-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court. On November 30, 2010, S&P withdrew the counterparty credit, financial strength, and financial enhancement ratings of Ambac at the company's request. The November 30, 2010 rating action followed a directive by the Commissioner of Insurance of the State of Wisconsin to Ambac to establish a segregated account for certain insured exposure, primarily policies related to credit derivatives, residential mortgage backed securities, and other structured finance transactions. On April 7, 2011, Moody's withdrew the insurance financial strength rating of Ambac Assurance. Assured Guaranty Corp. ("Assured Guaranty") and Assured Guaranty Municipal Corp. ("Assured Municipal") (formerly Financial Security Assurance, Inc. ("FSA")). On July 1, 2009, Assured Guaranty Ltd. ("Assured"), the parent company of Assured Guaranty, completed the purchase of Financial Security Assurance Holdings Ltd., the parent of financial guaranty insurance company, FSA. Effective November 9, 2009, FSA was renamed "Assured Municipal." In certain states, Assured Municipal may operate under its prior name. Assured Municipal, a separately capitalized company, provides municipal bond insurance, while Assured Guaranty provides financial guaranty insurance to both the municipal and structured finance sectors. On January 17, 2013, Moody's downgraded the insurance financial strength ratings of Assured Guaranty to A3 from Aa3 and of Assured Municipal to A2 from Aa3, both with a stable outlook. The January 17, 2013 downgrade reflects Moody's reassessment of the business franchise, expected future profitability and financial flexibility of Assured Guaranty and Assured Municipal. On March 18, 2014 S&P raised the counterparty credit and financial strength ratings of both Assured Guaranty and Assured Municipal to AA from AA-, with a stable outlook. The March 18, 2014 upgrade reflects S&P's view that the competitive position of Assured Guaranty and Assured Municipal remains strong relative to its peers' in the bond insurance industry. Berkshire Hathaway Assurance Corp. ("BHAC"). On April 8, 2009, Moody's downgraded the insurance financial strength rating of BHAC from Aaa to Aa1, with a stable outlook. This downgrade reflects Moody's view concerning "the impact on Berkshire's key businesses of the severe decline in equity markets over the past year as well as the protracted economic recession." On February 4, 2010, S&P lowered the financial strength rating of BHAC from AAA to AA+, with a stable outlook, reflecting S&P's view that Berkshire's overall capital adequacy has weakened to levels no longer consistent with a AAA rating and is not expected to return to extremely strong levels in the near term. Build America Mutual Assurance Company ("BAM"). On July 23, 2012, S&P assigned an initial rating of AA to BAM's financial strength and counterparty credit ratings, with a stable outlook. These ratings based upon S&P's view that BAM holds a very strong competitive position with low industry risk, along with extremely strong capital adequacy and strong operating performance. CIFG Assurance North America, Inc. ("CIFG"). On November 11, 2009, Moody's announced that it will withdraw the insurance financial strength rating of CIFG. On February 16, 2010, S&P withdrew the counterparty credit, financial strength, and financial enhancement ratings of CIFG. Financial Guaranty Insurance Company ("FGIC"). On March 24, 2009, Moody's withdrew the insurance financial strength rating of FGIC. On April 22, 2009, S&P withdrew the counterparty credit, financial strength, and financial enhancement ratings of FGIC.

Municipal Assurance Corporation ("MAC"). On March 18, 2014, S&P raised its financial strength and enhancement rating on MAC from AA- to AA. The rating action reflects S&P's view that MAC's competitive position remains strong relative to its peers' in the bond industry. S&P continues to view MAC as having a stable outlook. National Public Finance Guarantee Corporation ("National Guarantee") (formerly MBIA Insurance Corp. of Illinois ("MBIA Illinois")). On February 18, 2009, MBIA, Inc., the parent company of MBIA Insurance Corporation ("MBIA Corp."), announced the restructuring of its financial guaranty insurance operations following the approval of the New York and Illinois insurance regulators. The restructuring involves the segregation of its financial guaranty insurance operations into two separately capitalized sister companies, with MBIA Illinois assuming the risk associated with its US municipal exposures, and with MBIA Corp. insuring the remainder of the portfolio, including all international and structured finance exposures. Business recently ceded to MBIA Corp. from FGIC has been assigned to MBIA Illinois. On March 19, 2009, MBIA Illinois formally changed its name to National Public Finance Guarantee Corporation. National Guarantee is a wholly owned subsidiary of MBIA, Inc. and independently capitalized with $5.6 billion in claims-paying resources as of December 31, 2010. In certain states, National Guarantee may operate under its prior name.

TRUST ADMINISTRATION -------------------------------------------------------------------------------- Sponsor. Invesco Capital Markets, Inc. is the Sponsor of your Trust. The Sponsor is a wholly owned subsidiary of Invesco Advisers, Inc. ("Invesco Advisers"). Invesco Advisers is an indirect wholly owned subsidiary of Invesco Ltd., a leading independent global investment manager that provides a wide range of investment strategies and vehicles to its retail, institutional and high net worth clients around the globe. The Sponsor's principal office is located at 11 Greenway Plaza, Houston, Texas 77046-1173. As of March 31, 2015, the total stockholders' equity of Invesco Capital Markets, Inc. was $105,899,086.21 (unaudited). The current assets under management and supervision by Invesco Ltd. and its affiliates were valued at approximately $798.3 billion as of March 31, 2015. The Sponsor and your Trust have adopted a code of ethics requiring Invesco Ltd.'s employees who have access to information on Trust transactions to report personal securities transactions. The purpose of the code is to avoid potential conflicts of interest and to prevent fraud, deception or misconduct with respect to your Trust. The Information Supplement contains additional information about the Sponsor. If the Sponsor shall fail to perform any of its duties under the Trust Agreement or become incapable of acting or shall become bankrupt or its affairs are taken over by public authorities, then the Trustee may (i) appoint a successor Sponsor at rates of compensation deemed by the Trustee to be reasonable and not exceeding amounts prescribed by the Securities and Exchange Commission, (ii) terminate the Trust Agreement and liquidate the Trusts as provided therein or (iii) continue to act as Trustee without terminating the Trust Agreement. Trustee. The Trustee is The Bank of New York Mellon, a trust company organized under the laws of New York. The Bank of New York Mellon has its principal unit investment trust division offices at 2 Hanson Place, 12th Floor, Brooklyn, New York 11217, telephone (800) 856-8487. If you have any questions regarding your account or your Trust, please contact the Trustee at its principal unit investment trust division offices or your financial advisor. The Sponsor does not have access to individual account information. The Bank of New York Mellon is subject to supervision and examination by the Superintendent of Banks of the State of New York and the Board of Governors of the Federal Reserve System, and its deposits are insured by the Federal Deposit Insurance Corporation to the extent permitted by law. Additional information regarding the Trustee is set forth in the Information Supplement, including the Trustee's qualifications and duties, its ability to resign, the effect of a merger involving the Trustee and the Sponsor's ability to remove and replace the Trustee. See "Additional Information." Portfolio Administration. The Trusts are not managed funds and, except as provided in the Trust Agreement, bonds generally will not be sold or replaced. The Sponsor may, however, direct that bonds be sold in certain limited situations to protect the Trust based on advice from the Supervisor. These situations may include default in interest or principal payments on the bonds or other obligations of an issuer, an advanced refunding or institution of certain legal proceedings. In addition, the Trustee may sell bonds designated by the Supervisor for purposes of redeeming Units or payment of expenses. The Supervisor will consider a variety of factors in designating bonds to be sold including interest rates, market value and marketability. Except in limited circumstances, the Trustee will generally reject any offer by an issuer to issue bonds in exchange or substitution for the bonds (such as a refunding or refinancing plan). The Trustee will promptly notify Unitholders of any exchange or substitution. The Information Supplement contains a more detailed description of circumstances in which bonds may be sold or replaced. See "Additional Information." If a Trust is structured as a "regulated investment company" for federal tax purposes, the Sponsor may direct the reinvestment of proceeds of the sale of bonds if the sale is the direct result of serious adverse credit factors which, in the opinion of the Sponsor, would make retention of the bonds detrimental to the Trust. In such a case, the Sponsor may, but is not obligated to, direct the reinvestment of sale proceeds in any other securities that meet the criteria for inclusion in the trust on the Date of Deposit. The Sponsor may also instruct the Trustee to take action necessary to ensure that such a Trust continues to satisfy the qualifications of a regulated investment company and to avoid imposition of tax on undistributed income of the Trust. Replacement Bonds. No assurance can be given that a Trust will retain its present size or composition because bonds may be sold, redeemed or mature from time to time and the proceeds will be distributed to Unitholders and will not be reinvested. In the event of a failure to deliver any bond that has been purchased under a contract ("Failed Bonds"), the Sponsor is authorized under the Trust Agreement to direct the Trustee to acquire other bonds ("Replacement Bonds") to make up the original portfolio of a Trust. Replacement Bonds must be purchased within 20 days after delivery of the notice of the failed contract and the purchase price (exclusive of accrued interest) may not exceed the amount of funds reserved for the purchase of the Failed Bonds. The Replacement Bonds must be substantially identical to the Failed Bonds in terms of (i) the exemption from federal and state taxation, (ii) maturity, (iii) yield to maturity and current return and (iv) Standard & Poor's or Moody's ratings. The Trustee shall notify all Unitholders of a Trust within five days after the acquisition of a Replacement Bond and shall make a pro rata distribution of the amount, if any, by which the cost of the Failed Bond exceeded the cost of the Replacement Bond plus accrued interest. If Failed Bonds are not replaced, the Sponsor will refund the sales charge attributable to the Failed Bonds to all Unitholders of the Trust and distribute the principal and accrued interest (at the coupon rate of the Failed Bonds to the date of removal from the Trust) attributable to the Failed Bonds within 30 days after removal. All interest paid to a Unitholder which accrued after the expected date of settlement for Units will be paid by the Sponsor and accordingly will not be treated as tax-exempt income. If Failed Bonds are not replaced, the Estimated Net Annual Interest Income per Unit would be reduced and the Estimated Current Return and Estimated Long-Term Return might be lowered. Unitholders may not be able to reinvest their proceeds in other securities at a yield equal to or in excess of the yield of the Failed Bonds. Amendment of Trust Agreement. The Sponsor and the Trustee may amend the Trust Agreement without the consent of Unitholders to correct any provision which may be defective or to make other provisions that will not materially adversely affect the interest of the Unitholders (as determined in good faith by the Sponsor and the Trustee) or to maintain the tax status of a Trust. The Trust Agreement may not be amended to increase the number of Units or to permit the acquisition of bonds in addition to or in substitution for any of the bonds initially deposited in a Trust, except for the substitution of certain refunding bonds. The Trustee will notify Unitholders of any amendment. Termination of Trust Agreement. A Trust will terminate upon the redemption, sale or other disposition of the last bond held in the Trust. A Trust may also be terminated at any time by consent of Unitholders of 75% of the Units then outstanding or by the Trustee when the value of the Trust is less than 20% of the original principal amount of bonds. A Trust will be liquidated by the Trustee in the event that a sufficient number of Units not yet sold are tendered for redemption by the Underwriters, including the Sponsor, so that the net worth of such Trust would be reduced to less than 40% of the initial principal amount of such Trust. If a Trust is liquidated because of the redemption of unsold Units by the Underwriter, the Sponsor will refund to each purchaser of Units the entire sales charge paid by such purchaser. The Trustee will notify each Unitholder of any termination within a reasonable time and will then liquidate any remaining bonds. The sale of bonds upon termination may result in a lower amount than might otherwise be realized if the sale was not required at that time. For this reason, among others, the amount realized by a Unitholder upon termination may be less than the principal amount of bonds per Unit or value at the time of purchase. The Trustee will distribute to each Unitholder his share of the balance of the Interest and Principal Accounts after deduction of costs, expenses or indemnities. The Unitholder will receive a final distribution statement with this distribution. When the Trustee in its sole discretion determines that any amounts held in reserve are no longer necessary, it will distribute these amounts to Unitholders. The Information Supplement contains further information regarding termination of a Trust. See "Additional Information." Limitation on Liabilities. The Sponsor, Supervisor, Evaluator and Trustee shall be under no liability to Unitholders for taking any action or for refraining from taking any action in good faith pursuant to the Trust Agreement, or for errors in judgment, but shall be liable only for their own willful misfeasance, bad faith or gross negligence (negligence in the case of the Trustee) in the performance of their duties or by reason of their reckless disregard of their obligations and duties hereunder. The Trustee shall not be liable for depreciation or loss incurred by reason of the sale by the Trustee of any of the bonds. In the event of the failure of the Sponsor to act under the Trust Agreement, the Trustee may act thereunder and shall not be liable for any action taken by it in good faith under the Trust Agreement. The Trustee is not liable for any taxes or governmental charges imposed on the bonds, on it as Trustee under the Trust Agreement or on a Trust which the Trustee may be required to pay under any present or future law of the United States of America or of any other taxing authority having jurisdiction. In addition, the Trust Agreement contains other customary provisions limiting the liability of the Trustee. The Trustee and Sponsor may rely on any evaluation furnished by the Evaluator and have no responsibility for the accuracy thereof. Determinations by the Evaluator shall be made in good faith upon the basis of the best information available to it; provided, however, that the Evaluator shall be under no liability to the Trustee, Sponsor or Unitholders for errors in judgment. FEDERAL TAX STATUS -------------------------------------------------------------------------------- This is a general discussion of certain federal income tax consequences arising from the purchase, ownership and disposition of Units of a Trust that intends to qualify as a "regulated investment company" for federal income tax purposes. The summary is limited to investors who hold the Units as "capital assets" (generally, property held for investment) within the meaning of the Internal Revenue Code of 1986, as amended (the "Code"). Unitholders should consult their own tax advisers in determining the federal, state, local and any other tax consequences of the purchase, ownership and disposition of Units. Tax Status of the Trusts. The Trusts have elected to qualify and intend to qualify annually as regulated investment companies under Subchapter M of the Code. To qualify as a regulated investment company, a Trust must distribute to its Unitholders at least 90% of its investment company taxable income (which includes, among other items, dividends, taxable interest, if any, and the excess of net short-term capital gains over net long-term capital losses) and 90% of its tax-exempt interest income, and meet certain diversification of assets, source of income, and other requirements. By meeting these requirements, a Trust generally will not be subject to federal income tax on investment company taxable income, and on net capital gains (the excess of net long-term capital gains over net short-term capital losses) reported by a Trust as capital gain dividends, distributed to Unitholders. A Trust can also avoid an annual nondeductible 4% excise tax if each calendar year it distributes substantially all of its ordinary income, short- and long-term capital gain, and any previously undistributed and untaxed amounts. If for any taxable year a Trust did not qualify as a regulated investment company, all of its taxable income would be subject to tax at regular corporate rates without any deduction for distributions to Unitholders, and any distributions would be taxable to the Unitholders as ordinary dividends to the extent of such Trust's current or accumulated earnings and profits. Such distributions generally would be eligible for the dividends received deduction in the case of corporate Unitholders and the lower federal income tax rate currently applicable to qualifying dividend income for individual Unitholders, provided certain holding period requirements were satisfied by the Trust and the respective Unitholders. The Trusts may be subject to state or local tax in jurisdictions in which the Trusts are organized or may be deemed to be doing business. Distributions. Each Trust intends to make sufficient distributions of investment company taxable income, if any, capital gains, if any, and exempt-interest dividends each year in order to qualify as a regulated investment company and to avoid any Trust-level federal income or excise taxes. Each Trust intends to be eligible to distribute exempt-interest dividends to Unitholders by holding a sufficient amount of its assets in bonds generating interest that is exempt from federal income taxation under Section 103 of the Code. Such exempt-interest dividends are not subject to regular federal income tax, but may be subject to alternative minimum tax. Distributions of investment company taxable income (including net short-term capital gains), if any, are taxable to Unitholders as ordinary income, and generally will not qualify for treatment as qualified dividend income currently taxed at a maximum federal rate of 20% for individual Unitholders or for the dividends-received deduction for corporate Unitholders. Any income from your Trust that you must take into account for federal tax purposes is not reduced by amounts used to pay a deferred sales charge, if any. Net capital gains of a Trust (net long-term capital gain over net short-term capital loss), if any, realized and distributed by such Trust and reported as capital gain dividends are taxable to Unitholders as long-term capital gains currently at a maximum rate of 20%, without regard to the length of time the Unitholder may have held his or her Units in the Trust. Capital gain dividends are not eligible for the dividends-received deduction for corporate Unitholders. In determining the amount of capital gains to be distributed by a Trust, any capital loss carry over from a prior year will be taken into account in determining the amount of net long-term capital gain. Taxable distributions are taxable to investors whether received in cash or reinvested in additional Units. When the bonds owned by the Trusts were issued, special bond counsel issued opinions that the interest on the bonds is not subject to regular federal income tax (except in the limited circumstances referred to below). Payments that a Trust receives on a bank letter of credit, guarantee or insurance policy because the bond issuer has defaulted should be treated as payments on the bond, namely as payments of principal or interest that are not subject to regular federal income tax or taxable market discount or capital gain. The tax-exempt status of the interest depends on compliance by the issuer and others with ongoing requirements, and the opinions of bond counsel assume that these requirements will be met. However, there is no guarantee that the issuers (and other users) will comply with these requirements. A Trust may have to accrue and distribute income not yet received if it invests in bonds issued at a discount. A Trust may be required to sell bonds that it otherwise would have continued to hold in order to generate sufficient cash to make this distribution. The interest on some private activity bonds is a preference item included in alternative minimum taxable income. Each year the Trusts will give to Unitholders a report showing the percentage of the Trust's income that is a preference item. In addition, alternative minimum taxable income of a corporate Unitholder is increased by part of the excess of its "adjusted current earnings" (an alternative measure of income that includes interest on all tax exempt securities) over the amount otherwise determined to be alternative minimum taxable income. Therefore, the exempt-interest dividends may cause a Unitholder to have to pay the federal alternative minimum tax or may increase the amount of that tax payable by a Unitholder already subject to federal alternative minimum tax. The Trusts may own bonds originally issued at a discount. In general, original issue discount is the difference between the price at which a bond was issued and its stated redemption price at maturity. Original issue discount on tax-exempt bonds accrues as tax-exempt interest over the life of the bond. A Trust's adjusted tax basis for a bond issued with original issue discount will include original issue discount accrued during the period it held the bond. A Trust may also pay a premium when it buys a bond, even a bond issued with original issue discount. A Trust may be required to amortize the premium over the term of the bond and reduce its basis for the bond even though it does not get any deduction for the amortization. Therefore, sometimes the Trust may have a taxable gain when it sells a bond for an amount equal to or less than its original tax basis. Unitholders may receive ordinary income dividends from a Trust if the Trust sells or redeems bonds that were acquired at a market discount, or sells bonds at a short term capital gain. In general, the Internal Revenue Service ("IRS") will treat Bonds as market discount bonds when the cost of the bond, plus any original issue discount that has not yet accrued, is less than the amount due to be paid at the maturity of the bond. The IRS generally taxes all or a portion of the gain on the sale of a market discount bond as ordinary income when the bond is sold, redeemed or paid. The portion of the gain taxed by the IRS as ordinary income is equal to the portion of the market discount that has accrued since the seller purchased the bond. Some of the bonds held by the Trusts may lose their tax-exempt status while they are owned by a "substantial user" of the facilities being financed with the proceeds of those bonds, or by persons related to a substantial user. A "substantial user" is a person whose gross revenue derived with respect to the facilities financed by the bonds is more than 5% of the total revenue derived by all users of those facilities, or who occupies more than 5% of the usable area of the facilities or for whom the facilities or a part thereof were specifically constructed, reconstructed or acquired. "Related persons" are certain related individuals, affiliated corporations, partners and partnerships. This rule would not change the tax-exempt status of interest on bonds held by other persons. These rules may apply to a Unitholder who receives exempt-interest dividends attributable to interest on bonds that financed facilities for which such Unitholder or a related person is a "substantial user." Individuals must take exempt-interest dividends into consideration in computing the portion, if any, of social security benefits that will be included in their gross income and subject to federal income tax. If a Trust declares dividends in October, November or December that are payable to Unitholders of record on a date during those months, Unitholders must take the dividends into account for tax purposes in the year the dividend was declared, if the dividend is paid either in the year declared or in January of the following year. Ordinary, exempt-interest and capital gain dividends will be taxable as described above whether received in cash or reinvested in additional Units. If a Trust invests in securities of foreign issuers, it may be subject to withholding and other similar income taxes imposed by a foreign country. Dividends and distributions may also be subject to state and local taxes. Investors should carefully consider the tax implications of buying Units prior to a distribution by a Trust. The price of Units purchased at that time includes the amount of the forthcoming distributions. Distributions by a Trust reduce the net asset value of such Trust's Units, and if a distribution reduces the net asset value below a Unitholder's cost basis, such distribution, nevertheless, could be taxable to the Unitholder as ordinary income or capital gain as described above, even though, from an economic standpoint, it may constitute a partial return of capital. Sale or Redemption of Units. Upon the taxable disposition (including a sale or redemption) of Units of a Trust, a Unitholder may realize a gain or loss depending upon such Unitholder's adjusted tax basis in the Units and the amount of sale or redemption proceeds. Such gain or loss will be treated as capital gain or loss if the Units are capital assets in the Unitholder's hands, and will be long-term or short-term, generally depending upon the Unitholder's holding period for the Units. Non-corporate Unitholders are currently subject to tax at a maximum federal rate of 20% on capital gains resulting from the disposition of Units held for more than 12 months (zero if the taxpayer is, and would be after accounting for such gains, subject to a federal tax bracket for ordinary income of 25% or less). However, a loss realized by a Unitholder on the disposition of Units with respect to which capital gains dividends have been paid will, to the extent of such capital gain dividends, also be treated as long-term capital loss if such shares have been held by the Unitholder for six months or less. Further, a loss realized on a disposition will be disallowed to the extent the Units disposed of are replaced (whether by reinvestment of distributions or otherwise) within a period of 61 days beginning 30 days before and ending 30 days after the Units are disposed of. In such a case, the basis of the Units acquired will be adjusted to reflect the disallowed loss. Capital losses in any year are deductible only to the extent of capital gains plus, in the case of a non-corporate taxpayer, $3,000 of ordinary income ($1,500 for married individuals filing separately). The Foreign Account Tax Compliance Act ("FATCA"). A 30% withholding tax on your Trust's distributions, including capital gains distributions, and on gross proceeds from the sale or other disposition of Units generally applies if paid to a foreign entity unless: (i) if the foreign entity is a "foreign financial institution" as defined under FATCA, the foreign entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the foreign entity is not a "foreign financial institution," it identifies certain of its U.S. investors or (iii) the foreign entity is otherwise excepted under FATCA. Pursuant to the rules above and the applicability of any intergovernmental agreements between the United States and the relevant foreign country, withholding under FATCA is required: (i) generally with respect to distributions from your Trust and (ii) with respect to certain capital gains distributions and gross proceeds from a sale or disposition of Units that occur on or after January 1, 2017. If withholding is required under FATCA on a payment related to your Units, investors that otherwise would not be subject to withholding (or that otherwise would be entitled to a reduced rate of withholding) on such payment generally will be required to seek a refund or credit from the IRS to obtain the benefit of such exemption or reduction. Your Trust will not pay any additional amounts in respect of amounts withheld under FATCA. You should consult your tax advisor regarding the effect of FATCA based on your individual circumstances. Backup Withholding. The Trusts generally must withhold and pay over to the U.S. Treasury as backup withholding at a current rate of 28% of the taxable dividends and other distributions paid to any individual Unitholder who either does not supply its taxpayer identification number, has not reported all of its dividends and interest income, or does not certify to a Trust that he or she is not subject to withholding. The social security number of an individual is his or her taxpayer identification number. Backup withholding also may be required for a Unitholder upon notification of the Trust by the IRS. Backup withholding is not an additional tax and any amounts withheld may be credited against a Unitholder's ultimate federal income tax liability if proper documentation is provided. Foreign Withholding. Unitholders who are not U.S. persons should consult their tax adviser regarding the U.S. and foreign tax consequences of ownership of Units, including the possibility that such a Unitholder may be subject to a U.S. withholding tax at a rate of 30% (or at a lower rate under an applicable income tax treaty) on amounts received from a Trust. Information Statements. After the end of each fiscal year for a Trust, the Trustee will furnish to each Unitholder a statement containing information regarding the amount of exempt-interest dividends, ordinary dividends, and capital gain dividends distributed to such Unitholder during the fiscal year. Investors Should Consult Their Tax Advisers. Prospective investors are urged to consult their own tax advisers concerning the federal, state, local, foreign, and any other tax consequences of the purchase, ownership and disposition of Units based on their individual circumstances. Additional tax information is contained in the Information Supplement. EXPENSES -------------------------------------------------------------------------------- General. The Trustee will periodically deduct from the Interest Account and, to the extent funds are not sufficient therein, from the Principal Account, amounts necessary to pay the expenses of the Trusts, provided that organization costs, and deferred sales charges, if any, are generally paid out of cash deposited in the Principal Account. The Trustee also may withdraw from these Accounts such amounts, if any, as it deems necessary to establish a reserve for any governmental charges payable out of the Trusts. Amounts so withdrawn shall not be considered a part of a Trust's assets until such time as the Trustee shall return all or any part of such amounts to the appropriate Accounts. Organization Costs. You and the other Unitholders will bear all or a portion of the organization costs and charges incurred in connection with the establishment of your Trust. These costs and charges will include the cost of the preparation, printing and execution of the trust agreement, registration statement and other documents relating to your Trust, federal and state registration fees and costs, the initial fees and expenses of the Trustee, and legal and auditing expenses. The Public Offering Price of Units includes the estimated amount of these costs. The Trustee will deduct these expenses from your Trust's assets at the end of the initial offering period or after six months, if earlier. Sponsor, Supervisor, Evaluator and Trustee. The Sponsor and the Supervisor, which is an affiliate of the Sponsor, will receive the annual fee indicated under "Summary of Essential Financial Information" for providing bookkeeping and administrative services and for providing portfolio supervisory services for the Trusts. These fees may exceed the actual costs of providing these services for a Trust but the total amount received for providing these services to all Invesco unit investment trusts will not exceed the total cost of providing the services in any calendar year. The Evaluator will receive the annual evaluation fee indicated under "Summary of Essential Financial Information" for evaluating each Trust's portfolio. For its services the Trustee will receive the fee indicated under "Summary of Essential Financial Information" (which may be reduced as described therein). Part of the Trustee's compensation for its services is expected to result from the use of the funds being held in the Principal and Interest Accounts for future distributions, payment of expenses and redemptions since these Accounts are non-interest bearing to Unitholders. These fees are based on the outstanding principal amount of bonds and Units on the Date of Deposit for the first year and as of the close of business on January 1 for each year thereafter. The Sponsor's, Supervisor's, Evaluator's and Trustee's fees may be increased without approval of the Unitholders by amounts not exceeding proportionate increases under the category "Services Less Rent of Shelter" in the Consumer Price Index for All Urban Consumers or, if this category is not published, in a comparable category. Miscellaneous Expenses. The following additional charges are or may be incurred by the Trusts: (a) fees of the Trustee for extraordinary services, (b) expenses of the Trustee (including legal and auditing expenses) and of counsel designated by the Sponsor, (c) various governmental charges, (d) expenses and costs of any action taken by the Trustee to protect the Trusts and the rights and interests of Unitholders, (e) indemnification of the Trustee for any loss, liability or expenses incurred by it in the administration of the Trusts without negligence, bad faith or willful misconduct on its part, (f) any special custodial fees payable in connection with the sale of any of the bonds in a Trust, (g) expenditures incurred in contacting Unitholders upon termination of the Trusts and (h) costs incurred to reimburse the Trustee for advancing funds to the Trusts to meet scheduled distributions (which costs may be adjusted periodically in response to fluctuations in short-term interest rates). Each Trust will pay the costs associated with updating its registration statement each year. The fees and expenses set forth herein are payable out of the Trusts. When such fees and expenses are paid by or owing to the Trustee, they are secured by a lien on the portfolio of the applicable Trust. If the balances in the Interest and Principal Accounts are insufficient to provide for amounts payable by a Trust, the Trustee has the power to sell bonds to pay such amounts.

Accordingly, an investment in a Trust should be made with an understanding of the characteristics of and risks associated with such bonds. The types of bonds included in each Trust are described under "Portfolio" in the related Prospectus. Neither the Sponsor nor the Trustee shall be liable in any way for any default, failure or defect in any of the bonds. General Obligation Bonds and Revenue Bonds. Certain of the bonds may be general obligations of a governmental entity that are backed by the taxing power of such entity. All other bonds in the Trusts are revenue bonds payable from the income of a specific project or authority and are not supported by the issuer's power to levy taxes. General obligation bonds are secured by the issuer's pledge of its faith, credit and taxing power for the payment of principal and interest. However, the taxing power of any governmental entity may be limited by provisions of state constitutions or laws and an entity's credit will depend on many factors. Some such factors are the entity's tax base, the extent to which the entity relies on federal or state aid, and other factors which are beyond the entity's control. Revenue bonds, on the other hand, are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source. There are, of course, variations in the security of the different bonds in a Trust, both within a particular classification and between classifications, depending on numerous factors. Housing Bonds. Certain of the bonds may be obligations which derive their payments from mortgage loans. Certain of such housing bonds may be FHA insured. Multi-family housing revenue bonds are payable primarily from mortgage loans to housing projects for low to moderate income families. Single family mortgage revenue bonds are issued for the purpose of acquiring from originating financial institutions notes secured by mortgages on residences located within the issuer's boundaries and owned by persons of low or moderate income. The ability of housing issuers to make debt service payments on their obligations may be affected by various economic and non-economic factors. Such factors include: occupancy levels, adequate rental income in multi-family projects, the rate of default on mortgage loans underlying single family issuers and the ability of mortgage insurers to pay claims. Mortgage loans are generally partially or completely prepaid prior to their final maturities as a result of events such as sale of the mortgaged premises, default, condemnation or casualty loss. Because these bonds are subject to extraordinary mandatory redemption in whole or in part from such prepayments of mortgage loans, a substantial portion of such bonds will probably be redeemed prior to their scheduled maturities or even prior to their ordinary call dates. Extraordinary mandatory redemption without premium could also result from the failure of the originating financial institutions to make mortgage loans in sufficient amounts within a specified time period. Additionally, unusually high rates of default on the underlying mortgage loans may reduce revenues available for the payment of principal of or interest on such mortgage revenue bonds. In each case the issuer of the bonds has covenanted to comply with applicable requirements and bond counsel to such issuer has issued an opinion that the interest on the bonds is exempt from federal income tax under existing laws and regulations. Certain issuers of housing bonds have considered various ways to redeem bonds they have issued prior to the stated first redemption dates for such bonds. In connection with the housing bonds held by a Trust, the Sponsor at the Date of Deposit is not aware that any of the respective issuers of such bonds are actively considering the redemption of such bonds prior to their respective stated initial call dates. Health Care Bonds. Certain of the bonds may be health care revenue bonds. Ratings of bonds issued for health care facilities are often based on feasibility studies that contain projections of occupancy levels, revenues and expenses. A facility's gross receipts and net income available for debt service may be affected by future events and conditions including, among other things, demand for services and the ability of the facility to provide the services required, physicians' confidence in the facility, management capabilities, competition with other health care facilities, efforts by insurers and governmental agencies to limit rates, legislation establishing state rate-setting agencies, expenses, the cost and possible unavailability of malpractice insurance, the funding of Medicare, Medicaid and other similar third party payor programs, government regulation and the termination or restriction of governmental financial assistance, including that associated with Medicare, Medicaid and other similar third party payor programs. It also may be necessary for a hospital or other health care facility to incur substantial capital expenditures or increased operating expenses to effect changes in its facilities, equipment, personnel and services. Hospitals and other health care facilities are additionally subject to claims and legal actions by patients and others in the ordinary course of business. There can be no assurance that a claim will not exceed the insurance coverage of a health care facility or that insurance coverage will be available to a facility. Public Utility and Wholesale Electric Bonds. Certain of the bonds may be obligations of public utility issuers, including those selling wholesale and retail electric power and gas. General problems of such issuers would include the difficulty in financing large construction programs in an inflationary period, the limitations on operations and increased costs and delays attributable to environmental considerations, the difficulty of the capital market in absorbing utility debt, the difficulty in obtaining fuel at reasonable prices and the effect of energy conservation. In addition, federal, state and municipal governmental authorities may from time to time review existing, and impose additional, regulations governing the licensing, construction and operation of nuclear power plants, which may adversely affect the ability of the issuers of certain of the bonds to make payments of principal and/or interest on such bonds. Water and Sewer Bonds. Certain of the bonds may be obligations of issuers whose revenues are derived from the sale of water and/or sewerage services. Such bonds are generally payable from user fees. The problems of such issuers include the ability to obtain timely and adequate rate increases, population decline resulting in decreased user fees, the difficulty of financing large construction programs, the limitations on operations and increased costs and delays attributable to environmental considerations, the increasing difficulty of obtaining or discovering new supplies of fresh water, the effect of conservation programs and the impact of "no-growth" zoning ordinances. Industrial Revenue Bonds. Certain of the bonds may be industrial revenue bonds ("IRBs"). IRBs have generally been issued under bond resolutions pursuant to which the revenues and receipts payable under the arrangements with the operator of a particular project have been assigned and pledged to purchasers. In some cases, a mortgage on the underlying project may have been granted as security for the IRBs. Regardless of the structure, payment of IRBs is solely dependent upon the creditworthiness of the corporate operator of the project or corporate guarantor. Corporate operators or guarantors may be affected by many factors which may have an adverse impact on the credit quality of the particular company or industry. These include cyclicality of revenues and earnings, regulatory and environmental restrictions, litigation resulting from accidents or environmentally-caused illnesses, extensive competition and financial deterioration resulting from a corporate restructuring pursuant to a leveraged buy-out, takeover or otherwise. Such a restructuring may result in the operator of a project becoming highly leveraged which may impact on such operator's creditworthiness which in turn would have an adverse impact on the rating and/or market value of such bonds. Further, the possibility of such a restructuring may have an adverse impact on the market for and consequently the value of such bonds, even though no actual takeover or other action is ever contemplated or effected. Lease Obligation Bonds. Certain of the bonds may be obligations that are secured by lease payments of a governmental entity (hereinafter called "lease obligations"). Lease obligations are often in the form of certificates of participation. Although the lease obligations do not constitute general obligations of the municipality for which the municipality's taxing power is pledged, a lease obligation is ordinarily backed by the municipality's covenant to appropriate for and make the payments due under the lease obligation. However, certain lease obligations contain "nonappropriation" clauses which provide that the municipality has no obligation to make lease payments in future years unless money is appropriated for such purpose on a yearly basis. A governmental entity that enters into such a lease agreement cannot obligate future governments to appropriate for and make lease payments but covenants to take such action as is necessary to include any lease payments due in its budgets and to make the appropriations therefor. A governmental entity's failure to appropriate for and to make payments under its lease obligation could result in insufficient funds available for payment of the obligations secured thereby. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. Higher Educations and Public Education Bonds. Certain of the bonds may be obligations of issuers which are, or which govern the operation of, schools, colleges and universities and whose revenues are derived mainly from ad valorem taxes or for higher education systems, from tuition, dormitory revenues, grants and endowments. General problems relating to school bonds include litigation contesting the state constitutionality of financing public education in part from ad valorem taxes, thereby creating a disparity in educational funds available to schools in wealthy areas and schools in poor areas. Litigation or legislation on this issue may affect the sources of funds available for the payment of school bonds in the Trusts. General problems relating to college and university obligations include the prospect of a declining percentage of the population consisting of "college" age individuals, possible inability to raise tuitions and fees sufficiently to cover increased operating costs, the availability and restrictions on the use of endowments and other funds, the uncertainty of continued receipt of federal grants and state funding, and government legislation or regulations which may adversely affect the revenues or costs of such issuers. Airport and Transportation Bonds. Certain of the bonds in certain of the Trusts may be obligations which are payable from and secured by revenues derived from the ownership and operation of facilities such as airports, bridges, turnpikes, port authorities, convention centers and arenas. The major portion of an airport's gross operating income is generally derived from fees received from signatory airlines pursuant to use agreements which consist of annual payments for leases, occupancy of certain terminal space and service fees. Airport operating income may therefore be affected by the ability of the airlines to meet their obligations under the use agreements. From time to time the air transport industry has experienced significant variations in earnings and traffic, due to increased competition, excess capacity, increased costs, deregulation, traffic constraints, acts of terrorism and other factors, and several airlines have experienced severe financial difficulties. Similarly, payment on bonds related to other facilities is dependent on revenues from the projects, such as user fees from ports, tolls on turnpikes and bridges and rents from buildings. Therefore, payment may be adversely affected by reduction in revenues due to such factors as increased cost of maintenance, decreased use of a facility, lower cost of alternative modes of transportation, scarcity of fuel and reduction or loss of rents. Waste Disposal Bonds. Certain of the bonds may be obligations which are payable from and secured by revenues derived from the operation of resource recovery facilities. Resource recovery facilities are designed to process solid waste, generate steam and convert steam to electricity. Resource recovery bonds may be subject to extraordinary optional redemption at par upon the occurrence of certain circumstances, including but not limited to: destruction or condemnation of a project; contracts relating to a project becoming void, unenforceable or impossible to perform; changes in the economic availability of raw materials, operating supplies or facilities necessary for the operation of a project or technological or other unavoidable changes adversely affecting the operation of a project; and administrative or judicial actions which render contracts relating to the projects void, unenforceable or impossible to perform or impose unreasonable burdens or excessive liabilities. The Sponsor cannot predict the causes or likelihood of the redemption of resource recovery bonds in a Trust prior to the stated maturity of the bonds. Original Issue Discount Bonds. Certain of the bonds may have been acquired at a market discount from par value at maturity. The coupon interest rates on discount bonds at the time they were purchased and deposited in a Trust were lower than the current market interest rates for newly issued bonds of comparable rating and type. If such interest rates for newly issued comparable bonds increase, the market discount of previously issued bonds will become greater, and if such interest rates for newly issued comparable bonds decline, the market discount of previously issued bonds will be reduced, other things being equal. Investors should also note that the value of bonds purchased at a market discount will increase in value faster than bonds purchased at a market premium if interest rates decrease. Conversely, if interest rates increase, the value of bonds purchased at a market discount will decrease faster than bonds purchased at a market premium. In addition, if interest rates rise, the prepayment risk of higher yielding, premium Securities and the prepayment benefit for lower yielding, discount bonds will be reduced. A bond purchased at a market discount and held to maturity will have a larger portion of its total return in the form of taxable income and capital gain and less in the form of tax-exempt interest income than a comparable bond newly issued at current market rates. See "Federal Tax Status". Market discount attributable to interest changes does not indicate a lack of market confidence in the issue. Zero Coupon Bonds. Certain of the bonds may be "zero coupon" bonds. Zero coupon bonds are purchased at a deep discount because the buyer receives only the right to receive a final payment at the maturity of the bond and does not receive any periodic interest payments. The effect of owning deep discount bonds which do not make current interest payments (such as the zero coupon bonds) is that a fixed yield is earned not only on the original investment but also, in effect, on all discount earned during the life of such obligation. This implicit reinvestment of earnings at the same rate eliminates the risk of being unable to reinvest the income on such obligation at a rate as high as the implicit yield on the discount obligation, but at the same time eliminates the holder's ability to reinvest at higher rates in the future. For this reason, zero coupon bonds are subject to substantially greater price fluctuations during periods of changing market interest rates than are securities of comparable quality which pay interest. "When, as and if Issued" Bonds. Certain of the bonds may have been purchased on a "when, as and if issued" or "delayed delivery" basis. The delivery of any such bonds may be delayed or may not occur. Interest on these bonds begins accruing to the benefit of Unitholders on their respective dates of delivery. To the extent any bonds are actually delivered to a Trust after their respective expected dates of delivery, Unitholders who purchase their Units prior to the date such bonds are actually delivered to the Trustee would be required to adjust their tax basis in their Units for a portion of the interest accruing on such bonds during the interval between their purchase of Units and the actual delivery of such bonds. As a result of any such adjustment, the Estimated Current Returns during the first year would be slightly lower than those stated in the prospectus which would be the returns after the first year, assuming the portfolio of a Trust and estimated annual expenses other than that of the Trustee (which may be reduced in the first year only) do not vary from that set forth in the Prospectus. Unitholders will be "at risk" with respect to all bonds in the portfolios including "when, as and if issued" and "delayed delivery" bonds (i.e., may derive either gain or loss from fluctuations in the evaluation of such bonds) from the date they commit for Units. Redemption or Sale Prior to Maturity. Certain of the bonds may be subject to redemption prior to their stated maturity date pursuant to sinking fund provisions, call provisions or extraordinary optional or mandatory redemption provisions or otherwise. A sinking fund is a reserve fund accumulated over a period of time for retirement of debt. A callable debt obligation is one which is subject to redemption or refunding prior to maturity at the option of the issuer. A refunding is a method by which a debt obligation is redeemed, at or before maturity, by the proceeds of a new debt obligation. In general, call provisions are more likely to be exercised when the offering side valuation is at a premium over par than when it is at a discount from par. The exercise of redemption or call provisions will (except to the extent the proceeds of the called bonds are used to pay for Unit redemptions) result in the distribution of principal and may result in a reduction in the amount of subsequent interest distributions; it may also affect the current return on Units of the Trust involved. Each Trust portfolio contains a listing of the sinking fund and call provisions, if any, with respect to each of the debt obligations. Extraordinary optional redemptions and mandatory redemptions result from the happening of certain events. Generally, events that may permit the extraordinary optional redemption of bonds or may require the mandatory redemption of bonds include, among others: a final determination that the interest on the bonds is taxable; the substantial damage or destruction by fire or other casualty of the project for which the proceeds of the bonds were used; an exercise by a local, state or federal governmental unit of its power of eminent domain to take all or substantially all of the project for which the proceeds of the bonds were used; changes in the economic availability of raw materials, operating supplies or facilities or technological or other changes which render the operation of the project for which the proceeds of the bonds were used uneconomic; changes in law or an administrative or judicial decree which renders the performance of the agreement under which the proceeds of the bonds were made available to finance the project impossible or which creates unreasonable burdens or which imposes excessive liabilities, such as taxes, not imposed on the date the bonds are issued on the issuer of the bonds or the user of the proceeds of the bonds; an administrative or judicial decree which requires the cessation of a substantial part of the operations of the project financed with the proceeds of the bonds; an overestimate of the costs of the project to be financed with the proceeds of the bonds resulting in excess proceeds of the bonds which may be applied to redeem bonds; or an underestimate of a source of funds securing the bonds resulting in excess funds which may be applied to redeem bonds. The issuer of certain bonds in a Trust may have sold or reserved the right to sell, upon the satisfaction of certain conditions, to third parties all or any portion of its rights to call bonds in accordance with the stated redemption provisions of such bonds. In such a case the issuer no longer has the right to call the bonds for redemption unless it reacquires the rights from such third party. A third party pursuant to these rights may exercise the redemption provisions with respect to a bond at a time when the issuer of the bond might not have called a bond for redemption had it not sold such rights. The Sponsor is unable to predict all of the circumstances which may result in such redemption of an issue of bonds. See also the discussion of single family mortgage and multi-family revenue bonds above for more information on the call provisions of such bonds. To the best knowledge of the Sponsor, there is no litigation pending as of the Date of Deposit in respect of any bonds which might reasonably be expected to have a material adverse effect upon any of the Trusts. At any time after the Date of Deposit, litigation may be initiated on a variety of grounds with respect to bonds in a Trust. Such litigation, as, for example, suits challenging the issuance of pollution control revenue bonds under environmental protection statutes, may affect the validity of such bonds or the tax-free nature of the interest thereon. While the outcome of litigation of such nature can never be entirely predicted, each Trust has received or will receive opinions of bond counsel to the issuing authorities of each bond on the date of issuance to the effect that such bonds have been validly issued and that the interest thereon is exempt from federal income tax. In addition, other factors may arise from time to time which potentially may impair the ability of issuers to meet obligations undertaken with respect to the bonds. Puerto Rico Risk Factors Your Trust may invest significantly in bonds issued by issuers located in Puerto Rico ("Puerto Rico," or the "Commonwealth"). As further described under "Ratings", Puerto Rico's general obligation bonds are all currently rated below investment grade following a number of downgrades by the major credit rating agencies. As a result, the Commonwealth's access to the liquidity markets may be limited, and further, the Commonwealth may not be able to honor all of its obligations as they come due. Relevant History. Puerto Rico came under United States sovereignty in 1898. In 1950, Congress enacted Public Law 600, which provided that the existing political, economic and fiscal relationship between Puerto Rico and the United States would remain the same, but Puerto Rico would be authorized to draft and approve its own Constitution, guaranteeing a republican form of government. The Constitution of Puerto Rico was ratified by the United States Congress and subsequently approved by the President of the United States. Puerto Rico is a self-governing commonwealth in association with the United States. The United States and the Commonwealth share a common defense, market and currency. Puerto Rico exercises virtually the same control over its internal affairs as any of the fifty states of the United States. However, it differs from the states in its relationship with the United States federal government. The people of Puerto Rico are citizens of the United States but do not vote in national elections (they can only vote in local (Puerto Rico) elections). The people of the Commonwealth are represented in Congress by a Resident Commissioner who has a voice in the House of Representatives and limited voting power. The chief of state of the Commonwealth is the President of the United States. The head of government is an elected Governor. There are two legislative chambers: the House of Representatives and the Senate. Most federal taxes, except those such as Social Security taxes, are not levied in Puerto Rico. No federal income tax is collected from Puerto Rico residents on income sourced in Puerto Rico, except for certain federal employees who are subject to taxes on their salaries. Income earned by Puerto Rico residents from sources outside of Puerto Rico, however, is subject to federal income tax. Geographic Location and Demography. Puerto Rico is the fourth largest of the Caribbean islands and is located approximately 1,600 miles Southeast of New York. It is approximately 100 miles long and 35 miles wide. According to United States Census Bureau estimates, the population of Puerto Rico reflected a decrease to approximately 3,615,086 as of July 1, 2013, according to a United States Census Bureau estimate, compared to 3,725,789 in 2010. Changes in population have had, and may continue to have, an impact on economic growth and on the growth of tax revenues. Continued reductions in population, particularly of working age individuals, may have an adverse effect on tax and other government revenues that will not be entirely offset by reductions in government expenses in the short and medium term. In addition, the average age of the population of Puerto Rico is increasing, partly due to a reduction in birth rate, but primarily as a result of the migration of younger persons to the United States mainland. This may increase the demand for health and other services upon the Commonwealth, and the cost to the Commonwealth of providing such services, thus imposing limitations on the Commonwealth's ability to achieve a balanced budget and improve its financial condition. Relationship with the United States. While Puerto Rico has authority over its internal affairs, the United States controls interstate trade, foreign relations and commerce, customs administration, control of air, land and sea, immigration and emigration, nationality and citizenship, currency, maritime laws, military service, military bases, army, navy and air force, declaration of war, constitutionality of laws, jurisdictions and legal procedures, treaties, radio and television communications, agriculture, mining and minerals, highways, postal system, social security, and other areas generally controlled by the federal government in the United States. Puerto Rican institutions control internal affairs unless U.S. law is involved, as in matters of public health and pollution. Puerto Rico also lacks certain assignation of some revenues reserved for the states. Economy. The Commonwealth has established policies and programs directed principally at developing the manufacturing and services sectors of the economy and expanding and modernizing the Commonwealth's infrastructure. Domestic and foreign investment have been stimulated by selective tax exemptions, development loans, and other financial and tax incentives. Infrastructure expansion and modernization have been primarily financed by bonds and notes issued by the Commonwealth, its public corporations and municipalities. Economic progress has been aided by significant increases in the levels of education and occupational skills of the Commonwealth's population. The economy of Puerto Rico is closely linked to the United States economy, as most of the external factors that affect the local economy are determined by the policies and performance of the mainland economy. These external factors include exports, direct investment, the amount of federal transfer payments, the level of interest rates, the rate of inflation, and tourist expenditures. Approximately 71% of Puerto Rico's exports go to the United States and 42% of the imports come from the United States. In recent fiscal years, however, the performance of Puerto Rico's economy has not been consistent with the performance of the United States economy. Puerto Rico's economy entered a recession in the fourth quarter of fiscal year 2006. Puerto Rico has a diversified economy with manufacturing and services comprising its principal sectors. Puerto Rico's economy is closely linked to the United States economy. In fiscal year 2012 (which ended on June 30, 2012), the Commonwealth's gross national product (in current dollars) was $69.462 billion (preliminary), and personal income per capita (in current dollars) was $16,934 (preliminary). In the last three decades, industrial development in Puerto Rico has been relatively capital intensive and dependent on skilled labor. Puerto Rico has experienced mixed results in the service sector, which includes wholesale and retail trade, utilities, transportation and warehousing, information, finance and insurance, real estate and rental, and certain services such as professional, scientific, technical, management, administrative, support, educational, health care, social, recreational, accommodation, food and other services. This sector has expanded in terms of income over the past decade, following the general trend of other industrialized economies, but with differences on the magnitudes of those changes. The development of the service sector has been positively affected by demand generated by other sectors of the economy, such as manufacturing and construction. Tourism makes a significant contribution to economic activity. An estimated $3.2 billion were spent by visitors in Puerto Rico during fiscal year 2012. San Juan is the largest homeport for cruise ships in the Caribbean and one of the largest homeports for cruise ships in the world. During the fiscal year 2012, the number of persons registered in tourist hotels increased 9.4% compared with fiscal year 2011. The Puerto Rico Planning Board's preliminary reports on the performance of the Puerto Rico economy for fiscal year 2012 indicate that real gross national product increased 0.1% over fiscal year 2011. Nominal gross national product was $69.5 billion in fiscal year 2012, compared to $65.6 billion in fiscal year 2011. Aggregate personal income increased from $61.6 billion in fiscal year 2011 to $62.3 billion in fiscal year 2012, and personal income per capita increased from $16,611 in fiscal year 2011 to $16,934 in fiscal year 2012. According to the Household Survey, the number of persons employed in Puerto Rico during fiscal year 2012 averaged 1,035,465, a decrease of 1.1% compared to the previous fiscal year; and the unemployment rate averaged 15.2%. Debt, Revenues and Expenditures. Total assets and total liabilities of the Commonwealth's primary government at June 30, 2012 amounted to $16.3 billion and $55.3 billion, respectively, for a net deficit of $39 billion, compared to a $33.7 billion net deficit at the beginning of the current year. The Commonwealth has a net deficit of $47.2 billion in the governmental activities and a net deficit of $2.0 billion in the General Fund as of June 30, 2013, which has resulted from operating deficits over the last several years. The Commonwealth's high level of debt and the resulting required allocation of revenues to service this debt have contributed to these deficits and have adversely affected its credit ratings. The Commonwealth's expenses cover a range of services. The largest expenses were for general government, education, public housing and welfare, health, and public safety, which presented a combined increase of approximately $235.6 million when compared with prior fiscal year. In 2013, governmental activities' expenses exceeded program revenue by approximately $14.3 billion, resulting in the use of approximately $8.6 billion of general revenue and transfers from other funds (mostly taxes). As of February 2014, preliminary General Fund Revenues for the first seven months of fiscal year 2014 have exceeded aggregate General Fund revenues for the same period in fiscal year 2013 by approximately $593.3 million. The Commonwealth's very high level of debt has contributed to significant budget deficits during the past several years, which deficits the Commonwealth has been required to finance, further increasing the amount of its debt. More recently, the Commonwealth's high level of debt, among other factors, has adversely affected its credit ratings and its ability to obtain financing at favorable interest rates. Ratings. As of October 2014, the credit ratings of the Commonwealth's general obligation bonds were lowered to "B2" by Moody's Investors Service ("Moody's"), "BB" by Standard & Poor's Rating Services ("S&P"), and "BB-" by Fitch Ratings ("Fitch"), each of which is non-investment grade. S&P, Moody's and Fitch each assigned a negative outlook on the Commonwealth's ratings. Any explanation concerning the significance of such ratings must be obtained from the rating agencies. There is no assurance that any ratings will continue for any period of time or that they will not be revised or withdrawn. Credit Ratings and Liquidity. The liquidity of the Commonwealth has been adversely affected by the ratings downgrades described above, by the significant increase in credit spreads for obligations of the Commonwealth and its instrumentalities, by the limited market access experienced by the Commonwealth and its instrumentalities during the second half of 2013, and by a significant reduction of liquidity in the local Puerto Rico capital markets. Under current market conditions, in part as a result of the recent ratings downgrades, the Commonwealth may have limited capital market access. If the Commonwealth does not have sufficient access to the capital markets or alternative sources of financing to satisfy its liquidity needs, it may not be able to honor all of its obligations as they come due. Relationships with Creditors and Business Counterparties. Changes in the Commonwealth's credit ratings could affect its relationships with creditors and other business counterparties. For example, certain of the Commonwealth's short-term financings, variable rate debt obligations and mandatory tender bonds include provisions that permit the acceleration of such debt instruments based on the downgrade of the Commonwealth's ratings below investment grade. Moreover, the Commonwealth's interest rate exchange agreements include provisions that permit the counterparties to either request additional collateral or terminate the agreements based on the downgrade of the Commonwealth's ratings below investment grade. The Commonwealth recently optionally terminated certain of its interest rate exchange agreements and in connection therewith made aggregate termination payments of approximately $23.8 million to a counterparty. To date, however, the Commonwealth has not been required to post collateral in connection with any of its interest rate exchange agreements, and the Commonwealth's counterparties have not accelerated any debt obligations or terminated any interest rate exchange agreements as a result of such downgrades. If the counterparties entitled to accelerate debt obligations or terminate the remaining interest rate exchange agreements exercise their respective rights, there is no assurance that the Commonwealth would be able to honor all such obligations as they come due. Local Issuances. It should be noted that the creditworthiness of obligations issued by local Puerto Rican issuers may be unrelated to the creditworthiness of obligations issued by the Commonwealth of Puerto Rico, and there is no obligation on the part of the Commonwealth to make payment on such local obligations in the event of default. Many factors including national economic, social and environmental policies and conditions, which are not within the control of the issuers of such bonds, could affect or could have an adverse impact on the financial condition of the Commonwealth and various agencies and political subdivisions thereof. The Sponsor is unable to predict whether or to what extent such factors or other factors may affect the issuers of the bonds, the market value or marketability of such bonds or the ability of the respective issuers of such bonds acquired by certain trusts to pay interest on or principal of such bonds. The Puerto Rico bonds are susceptible to political, economic or regulatory factors affecting issuers of Puerto Rico municipal obligations. These include the possible adverse effects of certain Puerto Rico constitutional amendments, legislative measures, voter initiatives and other matters that are described. The information provided above is only a brief summary of the complex factors affecting the financial situation in Puerto Rico and is derived from sources that are generally available to investors and are believed to be accurate. No independent verification has been made as to the accuracy or completeness of any of the preceding information. It is based in part on information obtained from Commonwealth and local agencies in Puerto Rico or contained in Official Statements for various Puerto Rico obligations. Insurance on the Bonds Insurance has been obtained by the issuer of bonds or by a prior owner of such bonds prior to the deposit of such bonds in an Insured Trust guaranteeing prompt payment of interest and principal, when due, in respect of the bonds in such Insured Trust. See "The Trusts--Objective and Bond Selection". The premium for any insurance policy or policies obtained by an issuer of bonds has been paid by such issuer, and any such policy or policies are non-cancelable and will continue in force so long as the bonds so insured are outstanding and the preinsured bond insurer remains in business. Bond Insurers. The following is a description of the various preinsured bond insurers: ACA Financial Guaranty Corporation ("ACA Financial Guaranty"). ACA Financial Guaranty is organized and domiciled in the State of Maryland. Since December 2007, ACA Financial Guaranty has not issued any new financial guaranty insurance policies and is currently operating as a runoff insurance company. On August 8, 2008, ACA Financial Guaranty and counterparties to its structured finance products reached an agreement on a restructuring plan for ACA Financial Guaranty. The plan, approved by the Maryland Insurance Administration, provided for settlement of the structured finance obligations and protection for ACA Financial Guaranty's municipal policyholders. The settlement required that ACA Financial Guaranty make a $209 million cash payment and a distribution of surplus notes. The surplus notes provide the former collateralized debt obligation ("CDO") counterparties and certain other counterparties with approximately a 95% economic interest in ACA Financial Guaranty. ACA Financial Guaranty continues to operate as a runoff insurance company and focus on actively monitoring its remaining insured municipal obligations. As of September 30, 2012, ACA Financial Guaranty had total admitted assets of $436.3 million and total liabilities of $328.7 million, resulting in a surplus as regards policyholders of $107.6 million. On December 15, 2008, S&P raised the financial strength, financial enhancement, and issuer credit ratings on ACA Financial Guaranty to B from CCC, with a developing outlook. The upgrade reflected the positive effects of the restructuring transaction completed in August 2008 that settled all outstanding CDO and reinsurance exposures of the company, including the significantly deteriorated CDO of asset-backed securities ("ABS") transactions, eliminating a requirement to post a significant amount of collateral to the CDO of ABS counterparties. At the same time, S&P also withdrew the ratings at ACA Financial Guaranty's request. The information relating to ACA Financial Guaranty contained above has been furnished by ACA Financial Guaranty or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Ambac Assurance Corporation ("Ambac Assurance"). Ambac Financial Group, Inc. ("Ambac"), headquartered in New York City, is a holding company incorporated in the state of Delaware on April 29, 1991. Ambac's activities are divided into two business segments: (i) financial guarantee and (ii) financial services. Ambac provides financial guarantee insurance for public and structured finance obligations through its principal operating subsidiary, Ambac Assurance. As a holding company, Ambac is largely dependent on dividends from Ambac Assurance to pay principal and interest on its indebtedness and to pay its operating expenses. On June 5, 2008, S&P downgraded Ambac Assurance's insurance financial strength rating to AA from AAA, with negative implications. On June 19, 2008, Moody's downgraded Ambac Assurance's insurance financial strength rating from Aaa to Aa3, with a negative outlook. Moody's June 19, 2008 downgrade of Ambac Assurance's insurance financial strength rating reflects Ambac Assurance's overall credit profile in the current environment, including its significantly constrained new business prospects, its impaired financial flexibility and increased expected and stress loss projections among its mortgage-related risk exposures relative to previous estimates. On November 5, 2008, Moody's downgraded the insurance financial strength rating of Ambac Assurance from Aa3 to Baa1, with a developing outlook, as a result of greater than expected mortgage-related losses in the third quarter. On November 19, 2008, S&P lowered its insurance financial strength rating of Ambac Assurance to A from AA, with a negative outlook. The November 19, 2008 rating action on Ambac Assurance reflects S&P's view that Ambac Assurance's exposures in the U.S. residential mortgage sector and particularly the related collateralized debt obligation structures have been a source of significant and comparatively greater-than-competitor losses and will continue to expose the company to the potential for further adverse loss development. On April 13, 2009, Moody's downgraded the insurance financial strength rating of Ambac Assurance from Baa1 to Ba3, with a developing outlook, reflecting Ambac Assurance's weakened business position and very constrained financial flexibility, as well as its weakened risk adjusted capitalization, as Moody's loss estimates on residential mortgage-backed securities ("RMBS") have increased significantly. In Moody's view, these higher loss estimates increase the estimated capital required to support Ambac Assurance's sizable direct RMBS portfolio (including securities owned as well as securities guaranteed) and also the insurer's large portfolio of ABS CDO risks. On June 24, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of Ambac Assurance to BBB from A with negative implications. The June 24, 2009 rating action on Ambac Assurance reflects S&P's view that Ambac Assurance is effectively in runoff and the likelihood of the company continuing as an operating entity capable of writing new business has decreased significantly. On July 28, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of Ambac Assurance to CC from BBB, with a developing outlook. The July 28, 2009 rating action on Ambac Assurance reflects S&P's view of the significant deterioration in the Ambac Assurance's insured portfolio of nonprime RMBS and related CDOs, which has required the company to strengthen reserves to account for higher projected claims. In S&P's view, the additional reserves will have a significant negative effect on operating results, which will likely cause surplus to decline to below regulator required minimums. On July 29, 2009, Moody's downgraded the insurance financial strength rating of Ambac Assurance from Ba3 to Caa2, with a developing outlook, reflecting Moody's belief that, as a result of Ambac Assurance's recently announced large loss reserve increase and credit impairment charge estimated for the second quarter of 2009 which would reduce Ambac Assurance's regulatory capital to levels below the required minimum threshold, there will be increased pressure on Ambac Assurance's counterparties to commute outstanding exposures on terms that could imply a distressed exchange. On March 25, 2010, S&P revised the counterparty credit, financial strength, and financial enhancement ratings of Ambac Assurance to R from CC (an issuer rated "R" by S&P is under regulatory supervision because of its financial condition). S&P's March 25, 2010 rating action resulted following a directive by the Commissioner of Insurance of the State of Wisconsin to Ambac Assurance to establish a segregated account for certain insured exposure, primarily policies related to credit derivatives, RMBS, and other structured finance transactions. On March 26, 2010, Moody's placed the Caa2 insurance financial strength rating of Ambac Assurance on review for possible upgrade. On November 23, 2010, Moody's affirmed Ambac's Caa2 insurance financial strength rating, with a developing outlook. On November 30, 2010, S&P withdrew the counterparty credit, financial strength, and financial enhancement ratings of Ambac at the company's request. The November 30, 2010 rating action followed a directive by the Commissioner of Insurance of the State of Wisconsin to Ambac to establish a segregated account for certain insured exposure, primarily policies related to credit derivatives, residential mortgage-backed securities, and other structured finance transactions. On April 7, 2011, Moody's withdrew the insurance financial strength rating of Ambac Assurance. There have been a number of developments with respect to ratings actions by the rating agencies. As a result of these rating agency actions, as well as investor concern with respect to these actions, Ambac Assurance and its operating subsidiaries have been able to originate only a de minimis amount of new financial guarantee business since November 2007, and no new business in 2009. As a result, Ambac is no longer competing for new business. On March 25, 2010, Ambac announced that, at the direction of the Office of the Commissioner of Insurance of the State of Wisconsin ("OCI"), Ambac Assurance had established a segregated account for certain of its liabilities, primarily policies related to credit derivatives, RMBS and other structured finance transactions. This action derives from the OCI's view that immediate action is necessary to address Ambac Assurance's financial position. In conjunction with the establishment of the segregated account, the OCI has commenced rehabilitation proceedings with respect to liabilities contained in the segregated account in order to facilitate an orderly run-off and/or settlement of those specific liabilities. On June 7, 2010 Ambac announced that it had commuted all of its remaining CDOs of ABS and that certain other non-CDO of ABS exposures would be commuted within the next twelve months. On November 8, 2010, Ambac announced that it has filed for a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the Southern District of New York (the "Bankruptcy Court"). Ambac will continue to operate in the ordinary course of business as "debtor-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court. Ambac Assurance is subject to insurance regulatory requirements of the States of Wisconsin and New York, and the other jurisdictions in which it is licensed to conduct business. Ambac Assurance's statutory policyholder surplus and qualified statutory capital were $100.0 million and $628.3 million at September 30, 2012, respectively as compared to $495.3 million and $684.6 million as of December 31, 2011, respectively. As of September 30, 2012, total stockholders' deficit was $3.49 billion; at December 31, 2011, total stockholders' deficit was $3.15 billion. This increased deficit was primarily caused by the net loss for the nine months ended September 30, 2012, partially offset by unrealized gains on investment securities during the period. The information relating to Ambac Assurance contained above has been furnished by Ambac Assurance or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Assured Guaranty Corp. ("Assured Guaranty") and Assured Guaranty Municipal Corp. ("Assured Municipal") (formerly Financial Security Assurance Inc. ("FSA")). Assured Guaranty, a subsidiary of Assured Guaranty Ltd. ("Assured"), is organized in the State of Maryland and provides financial guaranty insurance to both the municipal and structured finance sectors. Assured Municipal, also a subsidiary of Assured, is a separately capitalized company organized in the State of New York and provides municipal bond insurance. In January 2009, Assured Guaranty finalized an agreement with CIFG Assurance North America, Inc. to assume a diversified portfolio of financial guaranty contracts totaling approximately $13.3 billion of net par outstanding. Assured Guaranty received $75.6 million, which included $85.7 million of upfront premiums net of ceding commissions and approximately $12.2 million of future installments related to this transaction. On July 1, 2009, Assured completed the purchase of Financial Security Assurance Holdings Ltd., the parent of financial guaranty insurance company, FSA, from Dexia Holdings Inc. Effective November 9, 2009, FSA was renamed Assured Guaranty Municipal Corp. In certain states, Assured Guaranty Municipal Corp. may operate under its prior name, Financial Security Assurance Inc. On June 24, 2010, S&P published a Full Analysis in which it affirmed its "AAA" financial strength ratings of Assured Guaranty and Assured Municipal, reflecting S&P's view of the companies' dominant market position in the bond insurance industry and their strong combined capital position. On October 25, 2010, S&P lowered the counterparty credit and financial strength ratings of both Assured Guaranty and Assured Municipal to AA+ from AAA, with a stable outlook. The downgrades reflect S&P's view of a struggling financial guarantee market, each company's weak statutory operating performance, and also the quality of each company's capital within S&P's capital adequacy analysis. On November 30, 2011 S&P lowered the counterparty credit and financial strength ratings of both Assured Guaranty and Assured Municipal to AA- from AA+, with a stable outlook. The November 30, 2011 downgrades reflect S&P's view that Assured Guaranty and Assured Municipal do not maintain enough capital to mitigate the largest obligor concentrations for a higher rating. On March 18, 2014 S&P raised the counterparty credit and financial strength ratings of both Assured Guaranty and Assured Municipal to AA from AA-, with a stable outlook. The March 18, 2014 upgrade reflects S&P's view that the competitive position of Assured Guaranty and Assured Municipal remains strong relative to its peers' in the bond insurance industry. On November 21, 2008, Moody's downgraded the insurance financial strength rating of Assured Guaranty from Aaa to Aa2, primarily reflecting Moody's updated view on Assured Guaranty's exposure to weakness inherent in the financial guaranty business model. Also on November 21, 2008, Moody's downgraded the insurance financial strength rating of FSA from Aaa to Aa3, reflecting Moody's view of FSA's diminished business and financial profile resulting from its exposure to losses on U.S. mortgage risks and disruption in the financial guaranty business more broadly. On November 12, 2009, Moody's downgraded the insurance financial strength rating of Assured Guaranty from Aa2 to Aa3, with a negative outlook. Moody's November 12, 2009 downgrade results from Moody's review of the performance of Assured's RMBS exposures. Moody's said that adverse trends in RMBS loss estimates have had varying effects on Assured's main insurance subsidiaries. On March 5, 2010, Moody's confirmed the insurance financial strength ratings of both Assured Guaranty and Assured Municipal at Aa3, with a negative outlook. On January 17, 2013, Moody's downgraded the insurance financial strength ratings of Assured Guaranty to A3 from Aa3 and of Assured Municipal to A2 from Aa3, both with a stable outlook. The January 17, 2013 downgrade reflects Moody's reassessment of the business franchise, expected future profitability and financial flexibility of Assured Guaranty and Assured Municipal. Assured's third quarter 2012 net income declined to $142 million from $761 million in third quarter 2011 due primarily to the effects of changes in credit spreads on the fair value of credit derivatives, offset in part by a decline in loss expense, which was significantly higher in the prior year due mainly to the effects of declining discount rates in the third quarter of 2011. Non-GAAP operating income in third quarter 2012 was $166 million, an increase from operating income in third quarter 2011, due primarily to higher net earned premiums due to refundings, accelerations and terminations, lower loss expense, and a lower effective tax rate on operating income. As of September 30, 2012, Assured Guaranty had total assets of $5.28 billion and total liabilities of $4.13 billion, resulting in total shareholder equity of $1.15 billion. As of September 30, 2012, Assured Municipal had total assets of $10.74 billion and total liabilities of $7.64 billion, resulting in total shareholder equity of $3.10 billion. The information contained above relating to Assured Guaranty and Assured Municipal and their parent company, Assured, is based upon publicly available information, or upon information that has been provided by the ratings agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Berkshire Hathaway Assurance Corp ("BHAC"). BHAC is a bond insurance company created by Berkshire Hathaway, Inc. ("Berkshire") in December 2007 and is licensed to write financial guarantee insurance in 49 states. On April 11, 2008, S&P assigned an initial rating of AAA to BHAC's insurance financial strength, with a stable outlook. On April 25, 2008, Moody's assigned an initial rating of Aaa to BHAC's insurance financial strength, with a stable outlook. On April 8, 2009, Moody's downgraded the insurance financial strength rating of BHAC from Aaa to Aa1, with a stable outlook. This downgrade reflects Moody's view concerning "the impact on Berkshire's key businesses of the severe decline in equity markets over the past year as well as the protracted economic recession." Moody's noted that Berkshire is also exposed to heightened volatility in its earnings and capital base related to market value fluctuations within its large portfolio of equity derivatives. On February 4, 2010, S&P lowered the financial strength rating of BHAC from AAA to AA+, with a stable outlook. The February 4, 2010 rating action was taken in anticipation of Berkshire's acquisition of Northern Santa Fe Corporation reflecting S&P's expectation that a significant part of the internal cash for the acquisition will come from Berkshire's core insurance operations and that Berkshire's overall capital adequacy has weakened to levels no longer consistent with a AAA rating and is not expected to return to extremely strong levels in the near term. As of September 30, 2012, Berkshire had total assets of $424.1 billion and total liabilities of $235.0 billion, resulting in total shareholder equity of $189.1 billion. The information relating to BHAC and its affiliates contained above has been furnished by BHAC or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Build America Mutual Assurance Company ("BAM"). BAM is a New York domiciled mutual insurance company owned by the issuers of municipal bonds who use BAM to insure their debt obligations. BAM officially launched on July 23, 2012 and began writing policies in September of 2012. On July 23, 2012, S&P assigned an initial rating of AA to BAM's financial strength and counterparty credit ratings, with a stable outlook. These ratings are based upon S&P's view that BAM holds a very strong competitive position with low industry risk, along with extremely strong capital adequacy and strong operating performance. As of September 30, 2012 BAM had total net admitted assets of $518.9 million and total liabilities of $27.9 million, resulting in a surplus as regards policyholders of $491.0 million. The information relating to BAM contained above has been furnished by BAM or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. CIFG Assurance North America, Inc. ("CIFG"). CIFG Holding, Inc. is the holding company for the CIFG group of financial guaranty insurance and reinsurance companies ("CIFG Group"), including CIFG Assurance North America, Inc., a New York corporation and its subsidiaries. The CIFG Group is actively managing the runoff of a portfolio of insured structured finance, municipal and infrastructure risks. On September 29, 2010, CIFG and CIFG Guaranty entered into a merger agreement which resulted in CIFG Guaranty merging into CIFG (together with related transactions, the "CIFG Merger"). On March 6, 2008, Moody's downgraded the insurance financial strength ratings of CIFG from Aaa to A1, with a stable outlook. This rating action reflected Moody's assessment of CIFG's weakened capitalization, impaired business opportunities, and uncertain strategic direction, as a result, in part, of its exposures to the U.S. residential mortgage market. Moody's believed that CIFG's significant exposure to the mortgage sector, especially ABS CDOs is indicative of a risk posture far greater than would be consistent with a Aaa rating going forward. On May 20, 2008, Moody's downgraded the insurance financial strength ratings of CIFG to Ba2 from A1, with direction uncertain, reflecting the high likelihood that, absent material developments, the company would fail minimum regulatory capital requirements in New York and Bermuda due to expected significant increases in modeled loss reserves on ABS CDOs. In Moody's view, the breach of such regulatory capital requirements would put the company in a precarious position, especially in light of the solvency provisions embedded in its CDS exposures. On October 28, 2008, Moody's downgraded the insurance financial strength rating of CIFG from Ba2 to B3, with direction uncertain, reflecting Moody's expectation of substantially higher mortgage-related losses arising from CIFG's insured portfolio, as well as the possibility that certain troubled exposures could be commuted. On January 22, 2009, Moody's upgraded the insurance financial strength rating of CIFG from B3 to Ba3, with a developing outlook, reflecting the strengthened capital adequacy profile of CIFG following its restructuring and the commutation of substantially all of its ABS CDO risks. Also on January 22, 2009, S&P raised the insurance financial strength rating of CIFG to BB from B, with a developing outlook. S&P's January 22, 2009 upgrade results from the completion of CIFG's restructuring plan involving key policyholders, creditors, and equity owners (counterparties) who had hedged their ABS CDO and commercial real estate CDO exposures with CIFG and which were significantly affected by defaults and downgrades of the underlying collateral. On June 15, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of CIFG to CC from BB, with a negative outlook, reflecting S&P's view of the significant deterioration in the company's insured portfolio of nonprime RMBS which has necessitated that CIFG strengthen reserves to account for the higher projected claims. On August 20, 2009, Moody's downgraded the insurance financial strength ratings of CIFG from Ba3 to Caa2, resulting from significant deterioration in the company's remaining insured portfolio since January, 2009 when CIFG initiated a broad restructuring. On November 11, 2009, Moody's downgraded the insurance financial strength ratings of CIFG from Caa2 to Ca. Also on November 11, 2009, Moody's announced that it will withdraw the insurance financial strength rating of CIFG. The November 11, 2009 rating actions reflect Moody's view that material deterioration in CIFG's insured portfolio adversely affected the guarantor's capital adequacy profile and Moody's believes that CIFG may no longer have sufficient financial resources to pay all insurance claims. On February 16, 2010, S&P withdrew the counterparty credit, financial strength, and financial enhancement ratings of CIFG. As of September 30, 2012, CIFG had net admitted assets of $742.3 million and total liabilities of $385.5 million. CIFG's statutory surplus as of September 30, 2012 is approximately $356.7 million, a decrease of approximately $227.8 million from approximately $584.5 million at December 31, 2011. This decrease is primarily attributable to unpaid losses and loss adjustment expense reserves established for student loans of approximately $252.3 million, which is partially offset by other income statement balances resulting in a net loss of approximately $227.0 million and an increase in contingency reserves of approximately $3.5 million. The information relating to CIFG and its affiliates contained above has been furnished by CIFG or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Financial Guaranty Insurance Company ("FGIC"). FGIC is a wholly owned subsidiary of FGIC Corporation. The company was engaged in the business of providing financial guaranty insurance and other forms of credit enhancement for public finance and structured finance obligations. In January 2008, FGIC voluntarily ceased writing financial guaranty policies concerning new or additional risks. The deterioration in the U.S. housing and mortgage markets and the global credit markets, which accelerated in the fourth quarter of 2007 and continued through the fourth quarter of 2009, has adversely affected the company's business, results of operations and financial condition. Specifically, the company incurred significant losses related to its exposure to certain ABS CDOs, which are backed primarily by subprime RMBS, and to certain RMBS, primarily backed by first-lien or second-lien mortgages. These losses have resulted in a substantial reduction of FGIC's statutory policyholders' surplus over time. On November 24, 2009, the New York State Insurance Department, the predecessor to the New York State Department of Financial Services, issued an order pursuant to Section 1310 of the New York Insurance Law requiring FGIC to, among other things, suspend paying any and all claims. FGIC was subsequently unable to eliminate the impairment of its policyholders' surplus through an out-of-court Surplus Restoration Plan. On June 11, 2012, Benjamin M. Lawsky, Superintendent of Financial Services of the State of New York (the "Superintendent") filed a verified petition with the Supreme Court of the State of New York for an order of rehabilitation (i) appointing the Superintendent as rehabilitator ("Rehabilitator") of FGIC, (ii) directing the Rehabilitator to take possession of the property and assets of FGIC and to conduct the business thereof, and (iii) directing the Rehabilitator to take steps towards the removal of the causes and conditions which have made FGIC's rehabilitation proceeding (the "Rehabilitation Proceeding") necessary. FGIC consented to the commencement of the Rehabilitation Proceeding. Prior to the fourth quarter of 2007, FGIC's financial strength was rated "Aaa" by Moody's "AAA" by S&P, and "AAA" by Fitch Ratings, Inc. ("Fitch"). Moody's, S&P and Fitch have since completed several assessments of FGIC's capital adequacy in relation to the company's exposure to ABS CDOs which are backed primarily by subprime RMBS, and its exposure to first-lien and second-lien RMBS. As a result of these assessments, Moody's, S&P and Fitch downgraded the financial strength ratings of FGIC. As of March 31, 2008, Fitch had downgraded FGIC from AA to BBB with Rating Watch Negative; Moody's had downgraded FGIC from A3 to Baa3; and S&P had downgraded FGIC from A to BB. On June 20, 2008, Moody's downgraded the insurance financial strength rating of FGIC from Baa3 to B1, reflecting FGIC's severely impaired financial flexibility and proximity to minimum regulatory capital requirements relative to Moody's estimates of expected case losses. On November 24, 2008, S&P lowered its insurance financial strength rating of FGIC to CCC from BB, with a negative outlook. S&P's November 24, 2008 downgrade results from FGIC's exposure to nonprime and second-lien mortgages and related CDO of ABS. On December 19, 2008, Moody's downgraded the insurance financial strength rating of FGIC from B1 to Caa1, with a negative outlook, reflecting Moody's expectation of higher mortgage-related losses arising from FGIC's insured portfolio and the constrained liquidity and financial flexibility of the holding company. On March 24, 2009, Moody's downgraded the insurance financial strength rating of FGIC from Caa1 to Caa3, with a negative outlook, reflecting Moody's expectation of higher mortgage-related losses arising from FGIC's insured portfolio, insufficient claims paying resources to cover Moody's estimate of expected loss, and the constrained liquidity and financial flexibility of FGIC's holding company. Also on March 24, 2009, Moody's withdrew the insurance financial strength rating of FGIC. On April 22, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of FGIC to CC from CCC, with a negative outlook. Also on April 22, 2009, S&P withdrew the ratings on FGIC and the counterparty credit rating on the holding company, FGIC Corporation, because of S&P's expectation that timely and comprehensive financial information will no longer be available. As of September 30, 2012, FGIC had net admitted assets of approximately $2.1 billion and total liabilities of approximately $5.8 billion. On August 4, 2010, FGIC Corporation announced that it had filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the Southern District of New York. None of FGIC Corporation's subsidiaries or affiliates, including FGIC, are part of the Chapter 11 filing. The information relating to FGIC and its affiliates contained above has been furnished by FGIC or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Municipal Assurance Corporation ("MAC"). MAC is a New York domiciled corporation providing municipal bond insurance for municipal and infrastructure bonds. MAC currently guarantees only public finance transactions. MAC is an Assured Guaranty company owned jointly by its affiliates Assured Guaranty Municipal Corp. and Assured Guaranty Corp. MAC is part of the Assured Guaranty Group. On July 17, 2013, S&P assigned MAC a long-term financial strength and counterparty credit rating of AA- to MAC with a stable outlook. On March 18, 2014, S&P raised its financial strength and enhancement rating on MAC from AA- to AA. The rating action reflects S&P's view that MAC's competitive position remains strong relative to its peers' in the bond industry. S&P continues to view MAC as having a stable outlook. As of June 30, 2014, MAC had a total net admitted assets of $1,519,869,768 and total liabilities of $999,277,625 resulting in a surplus as regards policyholders of $520,592,143. The information relating to MAC contained above is based upon publicly available information or upon information that has been provided by the ratings agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. National Public Finance Guarantee Corporation ("National Guarantee") (formerly MBIA Insurance Corp. of Illinois ("MBIA Illinois")). MBIA, Inc., a Connecticut corporation, conducts its financial guarantee business through though its wholly-owned subsidiaries MBIA Insurance Corporation ("MBIA Corp."), which writes global structured finance and non-U.S. public finance financial guarantee insurance, and National Guarantee, which writes U.S. public finance guarantees. On February 18, 2009, MBIA, Inc., the parent company of MBIA Corp., announced the restructuring of its financial guaranty insurance operations following the approval of the New York and Illinois insurance regulators. The restructuring involved the segregation of its financial guaranty insurance operations into two separately capitalized sister companies, with National Guarantee assuming the risk associated with its U.S. municipal exposures, and with MBIA Corp. insuring the remainder of the portfolio, including all international and structured finance exposures. Business ceded to MBIA Corp. from FGIC in 2008 has been assigned to National Guarantee. To provide additional protection for its municipal bond policyholders, National Guarantee has also issued second-to-pay policies for the benefit of the policyholders covered by the reinsurance and assignment. The second-to-pay policies, which are a direct obligation of National Guarantee, will be held by The Bank of New York Mellon as insurance trustee. These policies provide that if MBIA Corp. or FGIC, as applicable, do not pay valid claims of their policyholders, the policyholders will then be able to make a claim directly against National Guarantee under the second-to-pay policies. On March 19, 2009, MBIA Illinois formally changed its name to National Public Finance Guarantee Corporation. Effective December 1, 2009, National Guarantee was redomesticated to the State of New York and is subject to insurance regulations and supervision of the State of New York. National Guarantee is a wholly owned subsidiary of MBIA, Inc. and independently capitalized with $5.6 billion in claims-paying resources as of December 31, 2010. In certain states, National Public Finance Guarantee Corporation may operate under its prior name, MBIA Insurance Corp. of Illinois. On June 5, 2008, S&P downgraded MBIA Corp.'s insurance financial strength rating to AA from AAA. On June 19, 2008, Moody's downgraded the insurance financial strength ratings of MBIA Corp. and its insurance affiliates from Aaa to A2. Moody's June 19, 2008 downgrade of MBIA Corp. and its insurance affiliates reflects MBIA Corp.'s limited financial flexibility and impaired franchise, as well as the substantial risk within its portfolio of insured exposures and a movement toward more aggressive capital management within the group. On November 7, 2008, Moody's downgraded the insurance financial strength rating of MBIA Corp. and its insurance affiliates from A2 to Baa1, with a developing outlook. Moody's November 7, 2008 downgrade of MBIA Corp. and its insurance affiliates reflects MBIA Corp.'s diminished business and financial profile resulting from its exposure to losses from U.S. mortgage risks and disruption in the financial guaranty business more broadly. On February 18, 2009, Moody's downgraded the insurance financial strength rating of MBIA Corp. from Baa1 to B3, with a developing outlook, reflecting MBIA Corp.'s substantial reduction in claims-paying resources relative to the remaining higher-risk exposures in its insured portfolio, given the removal of capital, and the transfer of unearned premium reserves associated with the ceding of its municipal portfolio to MBIA Illinois, as well as the continued deterioration of MBIA Corp.'s insured portfolio of largely structured credits, with stress reaching sectors beyond residential mortgage-related securities. Also on February 18, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of MBIA Corp. to BBB+ from AA, with a negative outlook. The February 18, 2009 rating action on MBIA Corp. reflects S&P's view that MBIA Corp.'s retained insured portfolio lacks sufficient sector diversity and with time could become more concentrated, and that MBIA Corp.'s 2005-2007 vintage direct RMBS, CDO of ABS, and other structured exposures are subject to continued adverse loss development that could erode capital adequacy. At the same time, S&P lowered the counterparty credit and financial strength ratings of MBIA Illinois to AA- from AA, reflecting MBIA Illinois's uncertain business prospects and capital. On June 5, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of MBIA Corp. to BBB from BBB+, with a negative outlook, resulting from MBIA Corp.'s increased loss assumptions on its 2005-2007 vintage direct RMBS and CDO of ABS and a change in the assumed tax benefit of tax-loss carryforwards. Also on June 5, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of National Guarantee to A from AA-, with a negative outlook, reflecting S&P's view of National Guarantee's uncertain business and capital-raising prospects. On September 28, 2009, S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of MBIA Corp. to BB+ from BBB, with a negative outlook, reflecting S&P's view that macroeconomic conditions continue to contribute to losses on the group's structured finance products. On December 22, 2010 S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of MBIA Corp. to B from BB+, with a negative outlook, reflecting increased stress case loss projections. Also on December 22, 2010 S&P lowered the counterparty credit, financial strength, and financial enhancement ratings of National Guarantee to BBB from A, with a developing outlook. On December 19, 2011 Moody's downgraded the insurance financial strength rating of National Guarantee from Baa1 to Baa2, with a negative outlook, based upon weakening of the overall MBIA group's market standing as losses grow at National Guarantee's affiliated companies and the risk that resources at National Guarantee could be drawn away to support losses elsewhere within the group. On May 10, 2013 S&P raised the counterparty credit, financial strength, and financial enhancement ratings of National Guarantee to A from BB, with a stable outlook. The May 10, 2013 rating action reflects S&P's view that MBIA Corp. no longer acts as an anchor on the National Guarantee rating following the settlement with Societe Generale that ends litigation challenging National Guarantee's split from MBIA Corp. in 2009. On May 21, 2013 Moody's upgraded the insurance financial strength rating of MBIA Corp. to B3 from Caa2, with a positive outlook, citing MBIA Corp.'s improved capital and liquidity profile following settlements of putback receivables and insured claims with major counterparties. Also on May 21, 2013 Moody's upgraded the insurance financial strength rating of National Guarantee to Baa1 from Baa2, with a positive outlook. The May 21, 2013 rating action reflects National Guarantee's improved credit profile following the repayment of the loan from its weaker affiliate, MBIA Corp., and the termination of the litigation related to the 2009 restructuring. On March 18, 2014 S&P raised the counterparty credit, financial strength and financial enhancement ratings of National Guarantee to AA- from A, with a stable outlook. The March 18, 2014 upgrade reflects S&P's view that National Guarantee's prospective strong business risk profile and strong financial risk profile, based on the belief that the company will have a strong competitive position and strong operating performance, as well as its current extremely strong capital adequacy position. As of September 30, 2012, National Guarantee had total net admitted assets of $5.9 billion and total liabilities of $4.1 billion, resulting in a surplus as regard policyholders of $1.8 billion. As of September 30, 2012, MBIA, Inc. and its subsidiaries had total assets of $22.1 billion and total liabilities of $19.6 billion. MBIA, Inc.'s total shareholders' equity as of September 30, 2012 was $2.6 billion, increasing from $1.7 billion as of December 31, 2011. The information relating to MBIA and its affiliates contained above has been furnished by MBIA or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Radian Asset Assurance, Inc. ("Radian"). Radian Group Inc. ("Radian Group"), headquartered in Philadelphia, provides private mortgage insurance and related risk mitigation products and services to mortgage lenders nationwide through its principal operating subsidiary, Radian Guaranty Inc. ("Radian Guaranty"). Radian, a wholly-owned subsidiary of Radian Guaranty, is domiciled and licensed in New York as a financial guaranty insurer. In the third quarter of 2008, Radian discontinued writing any new financial guaranty business, including accepting reinsurance. On March 12, 2009, Moody's downgraded the insurance financial strength rating of Radian, as well as the ratings of its operational affiliates, from A3 to Ba1, with a stable outlook, reflecting the substantial deterioration in the credit profile of Radian Guaranty, coupled with increased loss estimates on Radian's pooled corporate exposures. On November 24, 2009, S&P lowered the financial strength, financial enhancement, and corporate credit ratings of Radian to BB from BBB- and left the ratings on CreditWatch with negative implications, reflecting S&P's view that adverse loss development in Radian's insured portfolio has resulted in higher capital charges and could result in further losses. On December 22, 2009, S&P lowered the financial strength, financial enhancement, and corporate credit ratings of Radian to BB- from BB, with a negative outlook. As of September 30, 2012, Radian Group had total assets of $6.45 billion and total liabilities of $5.43 billion. As of September 30, 2012, Radian had a statutory policyholders' surplus of $1.02 billion and a contingency reserve of $290.9 million. The information relating to Radian and its affiliates contained above has been furnished by Radian or the rating agencies. No representation is made herein as to the accuracy or adequacy of such information, or as to the existence of any adverse changes in such information subsequent to the date hereof. Syncora Guarantee Inc. ("Syncora Guarantee") (formerly XL Capital Assurance Inc. ("XLCA")). Syncora Guarantee, a wholly owned subsidiary of Syncora Holdings Ltd. ("Syncora Holdings"), is a New York domiciled financial guarantee insurance company which provides credit enhancement and protection products to the public finance and structured finance markets throughout the United States and internationally. In February 2008, Moody's downgraded the insurance financial strength ratings of XLCA to A3 from Aaa. On June 20, 2008, Moody's downgraded the insurance financial strength rating of XLCA from A3 to B2, reflecting XLCA's severely impaired financial flexibility and proximity to minimum regulatory capital requirements relative to Moody's estimates of expected case losses. On October 24, 2008, Moody's downgraded the insurance financial strength rating of Syncora Guarantee from B2 to Caa1. On November 18, 2008, S&P lowered its insurance financial strength rating of Syncora Guarantee to B from BBB- with developing expectations. S&P's November 18, 2008 downgrade resulted from the Syncora Guarantee's delay in implementing its restructuring plan and slow progress in its negotiations with counterparties of its CDO of ABS exposure. On January 29, 2009, S&P lowered the issuer credit and financial strength ratings of Syncora Guarantee to CC from B, with a negative outlook. S&P's January 29, 2009 downgrade resulted from S&P's recent update to its distressed exchange criteria. On March 9, 2009, Moody's downgraded the insurance financial strength rating of Syncora Guarantee from Caa1 to Ca, with a developing outlook, as a result of the large loss reserve and credit impairment charges taken by Syncora Guarantee on its mortgage-related exposures during the fourth quarter, which have resulted in a $2.4 billion statutory deficit at Syncora Guarantee as of December 31, 2008. On April 27, 2009, S&P revised the financial strength and financial enhancement ratings of Syncora Guarantee to R from CC (an issuer rated "R" by S&P is under regulatory supervision because of its financial condition). Also on April 27, 2009, S&P revised the counterparty credit rating of Syncora Guarantee to D from CC (an issuer rated "D" by S&P has failed to pay one or more of its financial obligation when it became due). S&P's April 27, 2009 rating actions resulted from Syncora Guarantee's announcement that pursuant to an order of the New York Insurance Department ("NYID"), the company must suspend any and all claims payments until it has restored its policyholders' surplus to a level greater than or equal to $65 million, the minimum the state requires. On July 28, 2010, S&P withdrew the D counterparty credit rating and the R financial strength and financial enhancement ratings of Syncora Guarantee. S&P's July 28, 2010 ratings actions resulted from S&P's belief that there is not sufficient information to judge Syncora Guarantee's claims paying ability. As of September 30, 2012, Syncora Guarantee had total assets of $1.17 billion and total liabilities of $639 million, resulting in a policyholders' surplus of $504.2 million. On July 20, 2010, Syncora Holdings announced that Syncora Guarantee has completed its remediation plan sufficient to meet its minimum statutory policyholder surplus requirements and address previously announced short and medium term liquidity issues. Also on July 20, 2010, Syncora Holdings announced that the NYID had approved Syncora Guarantee's plan for the payment of accrued and unpaid claims and for the payment of new claims as they become due in the ordinary course of business, resulting in the recommencement of claim payments by Syncora Guaranty on regularly scheduled payment dates occurring on or after July 21, 2010. The information relating to Syncora Guarantee and its affiliates contained above has been furnished by Syncora Guarantee or the rating agencies.

Portfolio Administration The Trustee is empowered to sell, for the purpose of redeeming Units tendered by any Unitholder, and for the payment of expenses for which funds may not be available, such of the bonds designated by the Supervisor as the Trustee in its sole discretion may deem necessary. The Supervisor, in designating such bonds, will consider a variety of factors including (a) interest rates, (b) market value and (c) marketability. The Sponsor, in connection with the Quality Trusts and Investment Grade Municipal Trusts, may direct the Trustee to dispose of bonds if the Supervisor determines that there exists any default in payment of principal or interest, institution of certain legal proceedings, default under other documents adversely affecting debt service, default in payment of principal or interest or other obligations of the same issuer, decline in projected income pledged for debt service on revenue bonds or decline in price or occurrence of other market or credit factors, including advance refunding (i.e., the issuance of refunding securities and the deposit of the proceeds thereof in trust or escrow to retire the refunded securities on their respective redemption dates), so that in the opinion of the Supervisor the retention of such bonds would be detrimental to the interest of the Unitholders. In connection with the Insured Trusts to the extent that bonds are sold which are current in payment of principal and interest in order to meet redemption requests and defaulted bonds are retained in the portfolio in order to preserve the related insurance protection applicable to said bonds, the overall quality of the bonds remaining in such Trust's portfolio will tend to diminish. Except as described in this section and in certain other unusual circumstances for which it is determined by the Trustee to be in the best interests of the Unitholders or if there is no alternative, the Trustee is not empowered to sell bonds from an Insured Trust which are in default in payment of principal or interest or in significant risk of such default and for which value has been attributed for the insurance obtained by such Insured Trust. Because of restrictions on the Trustee under certain circumstances, the Sponsor may seek a full or partial suspension of the right of Unitholders to redeem their Units in an Insured Trust. See "Rights of Unitholders--Redemption of Units". The Sponsor is empowered, but not obligated, to direct the Trustee to dispose of bonds in the event of an advanced refunding. The Trust is structured as a "regulated investment company" for federal tax purposes. The Sponsor may direct the reinvestment of proceeds of the sale of bonds if the sale is the direct result of serious adverse credit factors which, in the opinion of the Sponsor, would make retention of the bonds detrimental to the Trust. In such a case, the Sponsor may, but is not obligated to, direct the reinvestment of sale proceeds in any other securities that meet the criteria for inclusion in the trust on the Date of Deposit. The Sponsor may also instruct the Trustee to take action necessary to ensure that such a Trust continues to satisfy the qualifications of a regulated investment company and to avoid imposition of tax on undistributed income of the Trust. The Sponsor will generally instruct the Trustee to reject any offer made by an issuer of any of the bonds to issue new obligations in exchange or substitution for any bond pursuant to a refunding or refinancing plan, except that the Sponsor may instruct the Trustee to accept or reject such an offer or to take any other action with respect thereto as the Sponsor may deem proper if (1) the issuer is in default with respect to such bond or (2) in the written opinion of the Sponsor the issuer will probably default with respect to such bond in the reasonably foreseeable future. Any obligation so received in exchange or substitution will be held by the Trustee subject to the terms and conditions of the Trust Agreement to the same extent as bonds originally deposited thereunder. Within five days after the deposit of obligations in exchange or substitution for underlying bonds, the Trustee is required to give notice thereof to each Unitholder of the Trust thereby affected, identifying the bonds eliminated and the bonds substituted therefor. Except as stated herein and under "Trust Administration--Replacement Bonds" regarding the substitution of Replacement Bonds for Failed Bonds, the acquisition by a Trust of any securities other than the bonds initially deposited is not permitted. If any default in the payment of principal or interest on any bonds occurs and no provision for payment is made therefor within 30 days, the Trustee is required to notify the Sponsor thereof. If the Sponsor fails to instruct the Trustee to sell or to hold such bonds within 30 days after notification by the Trustee to the Sponsor of such default, the Trustee may in its discretion sell the defaulted bond and not be liable for any depreciation or loss thereby incurred. Sponsor Information Invesco Capital Markets, Inc. is the Sponsor of the Trust. The Sponsor is a wholly owned subsidiary of Invesco Advisers, Inc. ("Invesco Advisers"). Invesco Advisers is an indirect wholly owned subsidiary of Invesco Ltd., a leading independent global investment manager that provides a wide range of investment strategies and vehicles to its retail, institutional and high net worth clients around the globe. The Sponsor's principal office is located at 11 Greenway Plaza, Houston, Texas 77046-1173. As of March 31, 2015, the total stockholders' equity of Invesco Capital Markets, Inc. was $105,899,086.21 (unaudited). The current assets under management and supervision by Invesco Ltd. and its affiliates were valued at approximately $798.3 billion as of March 31, 2015. (This paragraph relates only to the Sponsor and not to the Trust or to any other Series thereof. The information is included herein only for the purpose of informing investors as to the financial responsibility of the Sponsor and its ability to carry out its contractual obligations. More detailed financial information will be made available by the Sponsor upon request.) The Sponsor and your Trust have adopted a code of ethics requiring Invesco Ltd.'s employees who have access to information on Trust transactions to report personal securities transactions. The purpose of the code is to avoid potential conflicts of interest and to prevent fraud, deception or misconduct with respect to your Trust. If the Sponsor shall fail to perform any of its duties under the Trust Agreement or become incapable of acting or shall become bankrupt or its affairs are taken over by public authorities, then the Trustee may (i) appoint a successor Sponsor at rates of compensation deemed by the Trustee to be reasonable and not exceeding amounts prescribed by the Securities and Exchange Commission, (ii) terminate the Trust Agreement and liquidate the Trusts as provided therein or (iii) continue to act as Trustee without terminating the Trust Agreement. Trustee Information The Trustee is The Bank of New York Mellon, a trust company organized under the laws of New York. The Bank of New York Mellon has its principal unit investment trust division offices at 2 Hanson Place, 12th Floor, Brooklyn, New York 11217, telephone (800) 856-8487. The Bank of New York Mellon is subject to supervision and examination by the Superintendent of Banks of the State of New York and the Board of Governors of the Federal Reserve System, and its deposits are insured by the Federal Deposit Insurance Corporation to the extent permitted by law. The duties of the Trustee are primarily ministerial in nature. It did not participate in the selection of bonds for the portfolios of any of the Trusts. In accordance with the Trust Agreement, the Trustee shall keep proper books of record and account of all transactions at its office for the Trusts. Such records shall include the name and address of every Unitholder of the Trusts. Such books and records shall be open to inspection by any Unitholder at all reasonable times during the usual business hours. The Trustee shall make such annual or other reports as may from time to time be required under any applicable state or Federal statute, rule or regulation. The Trustee is required to keep a certified copy or duplicate original of the Trust Agreement on file in its office available for inspection at all reasonable times during the usual business hours by any Unitholder, together with a current list of the bonds held in the Trusts. Under the Trust Agreement, the Trustee or any successor trustee may resign and be discharged of the trusts created by the Trust Agreement by executing an instrument in writing and filing the same with the Sponsor. The Trustee or successor trustee must mail a copy of the notice of resignation to all Unitholders then of record, not less than 60 days before the date specified in such notice when such resignation is to take effect. The Sponsor upon receiving notice of such resignation is obligated to appoint a successor trustee promptly. If, upon such resignation, no successor trustee has been appointed and has accepted the appointment within 30 days after notification, the retiring Trustee may apply to a court of competent jurisdiction for the appointment of a successor. The Sponsor may remove the Trustee and appoint a successor trustee as provided in the Trust Agreement at any time with or without cause. Notice of such removal and appointment shall be mailed to each Unitholder by the Sponsor. Upon execution of a written acceptance of such appointment by such successor trustee, all the rights, powers, duties and obligations of the original trustee shall vest in the successor. The resignation or removal of a Trustee becomes effective only when the successor trustee accepts its appointment as such or when a court of competent jurisdiction appoints a successor trustee. Any corporation into which a Trustee may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which a Trustee shall be a party, shall be the successor trustee. The Trustee must be a banking corporation organized under the laws of the United States or any state and having at all times an aggregate capital, surplus and undivided profits of not less than $5,000,000. Taxation The prospectus contains a discussion of certain material U.S. federal income tax issues concerning your Trust and the purchase, ownership and disposition of Trust Units. The discussion below supplements the prospectus discussion and is qualified in its entirety by the prospectus discussion. Prospective investors should consult their own tax advisors with regard to the federal tax consequences of the purchase, ownership, or disposition of Trust Units, as well as the tax consequences arising under the laws of any state, locality, non-U.S. country, or other taxing jurisdiction. The federal income tax summary below and in the prospectus is based in part on the advice of counsel to your Trust. The Internal Revenue Service could disagree with any conclusions set forth in these discussions. In addition, our counsel was not asked to review the assets to be held by your Trust. Your Trust intends to elect and to qualify annually as a "regulated investment company" under the Internal Revenue Code of 1986, as amended (the "Code") and to comply with applicable distribution requirements so that it will not pay federal income tax on income and capital gains distributed to its Unitholders. In addition, your Trust intends to hold a sufficient amount of its assets in bonds that are exempt from U.S. federal income taxation under Section 103 of the Code so as to qualify to distribute exempt-interest dividends to you. Such exempt-interest dividends are not subject to regular U.S. federal income tax, but may be subject to the alternative minimum tax. Your Trust may hold bonds issued by the Government of Puerto Rico or by its authority. Such bonds are exempt from taxation by the U.S. federal government, the government of Puerto Rico, any state or its political subdivisions, any possession of the United States, or the District of Columbia. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, your Trust must, among other things, (a) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, and net income from qualified publicly traded partnerships; (b) diversify its holdings so that, at the end of each quarter of the taxable year, (i) at least 50% of the market value of the Trust's assets is represented by cash and cash items (including receivables), U.S. Government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Trust's total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities (other than U.S. Government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Trust controls (by owning 20% or more of the issuer's outstanding voting securities) and which are engaged in the same, similar or related trades or businesses, or the securities of qualified publicly traded partnerships; and (c) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses but excludes net capital gain, if any) and at least 90% of its net tax-exempt interest income each taxable year. Complying with these requirements may result in the capital gains impact on Unitholders described in more detail in the next paragraph. As a regulated investment company, your Trust generally will not be subject to U.S. federal income tax on its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid), if any, and net capital gain (the excess of net long-term capital gain over net short-term capital loss), if any, that it distributes to Unitholders. Your Trust intends to distribute to its Unitholders, at least annually, substantially all of its investment company taxable income and net capital gain, if any. If your Trust retains any net capital gain or investment company taxable income, it will generally be subject to federal income tax at regular corporate rates on the amount retained. In addition, amounts not distributed on a timely basis in accordance with a calendar year distribution requirement are subject to a nondeductible 4% excise tax. In order to avoid this excise tax, your Trust must distribute during each calendar year an amount equal to the sum of (1) at least 98% of its ordinary income (not taking into account any capital gains or losses) for the calendar year, (2) at least 98.2% of its capital gains in excess of its capital losses (adjusted for certain ordinary losses) for the one-year period ending October 31 of the calendar year, and (3) any ordinary income and capital gains for previous years that were not distributed or taxed during those years. To prevent application of the excise tax, your Trust intends to make its distributions in accordance with the calendar year distribution requirement. However, there is no assurance that your Trust will make sufficient distributions to eliminate all tax liabilities in all periods. Your Trust may make taxable distributions even during periods in which the Trust's Unit price has declined. At certain times your Trust may recognize capital gains from securities sold to generate cash to satisfy Unitholder redemption requests. In order to satisfy the capital gains distribution requirement, your Trust may report a portion of other income earned during the year, or "reclassify" previously distributed income, including tax-exempt income, as taxable net capital gain, thereby avoiding the need to sell additional securities to generate the necessary funds to meet the distribution requirement. Further, if your Trust retains any net capital gain, the Trust may report the retained amount as undistributed capital gains in a notice to Unitholders who, if subject to federal income tax on long-term capital gains (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their share of such undistributed amount, and (ii) will be entitled to credit their proportionate share of the tax paid by the Trust against their federal income tax liabilities if any, and to claim refunds to the extent the credit exceeds such liabilities. A distribution will be treated as paid on December 31 of the current calendar year if it is declared by your Trust in October, November or December with a record date in such a month and paid by your Trust during January of the following calendar year. These distributions will be taxable to Unitholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received. If your Trust failed to qualify as a regulated investment company or failed to satisfy the 90% distribution requirement in any taxable year, the Trust would be taxed as an ordinary corporation on its taxable income (even if such income were distributed to its Unitholders) and all distributions out of earnings and profits would be taxed to Unitholders as ordinary dividend income. Investors in the Trust may be subject to state, local, or foreign taxes in connection with their investment in the Trust. Investors are encouraged to consult their own tax advisors regarding the specific federal (including the federal alternative minimum tax), state, local, and foreign tax consequences that may affect them as a result of an investment in the Trust. The Trust does not expect to seek any rulings from the Internal Revenue Service or opinions from tax counsel. Termination of the Trust Agreement A Trust may be terminated at any time by consent of Unitholders of 75% of the Units of such Trust then outstanding or by the Trustee when the value of such Trust, as shown by any semi-annual evaluation, is less than 20% of the original principal amount of bonds. A Trust will be liquidated by the Trustee in the event that a sufficient number of Units not yet sold are tendered for redemption by the Underwriters, including the Sponsor, so that the net worth of such Trust would be reduced to less than 40% of the initial principal amount of such Trust. If a Trust is liquidated because of the redemption of unsold Units by the Underwriters, the Sponsor will refund to each purchaser of Units the entire sales charge paid by such purchaser. The Trust Agreement provides that each Trust shall terminate upon the redemption, sale or other disposition of the last bond held in such Trust, but in no event shall it continue beyond the end of the year preceding the fiftieth anniversary of the Trust Agreement in the case of an IM-IT, an IM-IT Laddered Series, an Investment Grade Municipal, an Investment Grade Municipal Limited Maturity Trust, a 10-20 Year Trust an IM-IT Discount, a U.S. Territorial IM-IT, a High Grade Tax-Exempt Bond, 20+ Year Series, a Long-Term State or a National Quality Trust, or beyond the end of the year preceding the twentieth anniversary of the Trust Agreement in the case of a Strategic Municipal Trust Intermediate Series, an IM-IT Limited Maturity Trust, an IM-IT Intermediate Trust, a State Intermediate Trust, a State Intermediate Laddered Maturity Trust, an IM-IT Short Intermediate Trust, an Investment Grade Municipal Intermediate Trust, an Investment Grade Municipal 7-13 Year Trust, and a Quality Municipals Income Trust Limited Maturity Series. In the event of termination of any Trust, written notice thereof will be sent by the Trustee to each Unitholder of such Trust at his address appearing on the registration books of a Trust maintained by the Trustee. Within a reasonable time thereafter the Trustee shall liquidate any bond then held in such Trust and shall deduct from the funds of such Trust any accrued costs, expenses or indemnities provided by the Trust Agreement, including estimated compensation of the Trustee and costs of liquidation and any amounts required as a reserve to provide for payment of any applicable taxes or other government charges. The sale of bonds in the Trust upon termination may result in a lower amount than might otherwise be realized if such sale were not required at such time. For this reason, among others, the amount realized by a Unitholder upon termination may be less than the principal amount or par amount of bonds represented by the Units held by such Unitholder. The Trustee shall then distribute to each Unitholder his share of the balance of the Interest and Principal Accounts. With such distribution the Unitholder shall be furnished a final distribution statement of the amount distributable. At such time as the Trustee in its sole discretion shall determine that any amounts held in reserve are no longer necessary, it shall make distribution thereof to Unitholders in the same manner. Notwithstanding the foregoing, in connection with final distributions to Unitholders of an Insured Trust, it should be noted that because the portfolio insurance obtained by an Insured Trust, if any, is applicable only while bonds so insured are held by such Trust, the price to be received by such Trust upon the disposition of any such bond which is in default, by reason of nonpayment of principal or interest, will not reflect any value based on such insurance. Therefore, in connection with any liquidation, it shall not be necessary for the Trustee to, and the Trustee does not currently intend to, dispose of any bond or bonds if retention of such bond or bonds, until due, shall be deemed to be in the best interest of Unitholders, including, but not limited to, situations in which a bond or bonds so insured have deteriorated market prices resulting from a significant risk of default. Since the Preinsured Bonds will reflect the value of the related insurance, it is the present intention of the Sponsor not to direct the Trustee to hold any of such Preinsured Bonds after the date of termination. All proceeds received, less applicable expenses, from insurance on defaulted bonds not disposed of at the date of termination will ultimately be distributed to Unitholders of record as of such date of termination as soon as practicable after the date such defaulted bond or bonds become due and applicable insurance proceeds have been received by the Trustee. Description of Ratings Standard & Poor's, A Division of the McGraw-Hill Companies. A Standard & Poor's long-term debt obligation credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific debt obligation. This opinion of creditworthiness may take into consideration the creditworthiness of guarantors, insurers or other forms of credit enhancement on the obligation. The long-term debt obligation credit ratings are not a recommendation to purchase, sell or hold the debt obligation, inasmuch as they do not comment as to market price or suitability for a particular investor. The long-term debt obligation credit ratings are based on current information furnished by the obligor or obtained by Standard & Poor's from other sources it considers reliable. Standard & Poor's does not perform an audit in connection with any credit rating and may, on occasion, rely on unaudited financial information. Credit ratings may be changed, suspended or withdrawn as a result of changes in, or unavailability of, such information, or based on other circumstances. The long-term debt obligation credit ratings are based, in varying degrees, on the following considerations: I. Likelihood of payment--capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation. II. Nature of and provisions of the obligation. III. Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights. The credit rating definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations to reflect the lower priority in bankruptcy, as noted above. (Such differentiation applies when an entity has both senior and subordinate obligations, secured and unsecured obligations or operating company and holding company obligations.) Accordingly, in the case of junior debt, the rating may not conform exactly with the category definition. AAA--An obligation rated "AAA" has the highest rating assigned by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is extremely strong. AA--An obligation rated "AA" differs from the highest-rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong. A--An obligation rated "A" is somewhat more susceptible to adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong. BBB--An obligation rated "BBB" exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation. Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as having significant speculative characteristics. "BB" indicates the least degree of speculation and "C" the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions. Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories. NR--This indicates that no rating has been requested, that there is insufficient information on which to base a rating or that Standard & Poor's does not rate a particular obligation as a matter of policy. Moody's Investors Service. Moody's municipal ratings are opinions of the investment quality of issuers and issues in the U.S. municipal and tax-exempt markets. As such, these ratings incorporate Moody's assessment of the default probability and loss severity of these issuers and issues. The default and loss content for Moody's municipal long-term rating scale differs from Moody's general long-term rating scale. Municipal ratings are based upon the analysis of five primary factors relating to municipal finance: market position, financial position, debt levels, governance, and covenants. Each of the factors is evaluated individually and for its effect on the other factors in the context of the municipality's ability to repay its debt. Aaa--Issuers or issues rated Aaa demonstrate the strongest creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues. Aa--Issuers or issues rated Aa demonstrate very strong creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues. A--Issuers or issues rated A present above-average creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues. Baa--Issuers or issues rated Baa represent average creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues. Obligations rated "Ba," "B," "Caa," "Ca" and "C" are regarded as having significant speculative characteristics. "Ba" indicates the least degree of speculation and "C" the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions. Note: Moody's appends numerical modifiers 1, 2, and 3 to each generic rating category from Aa through Caa. The modifier 1 indicates that the issuer or obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Equivalent Taxable Estimated Current Return Tables The following table shows the approximate taxable estimated current returns for single and joint return filers that are equivalent to tax-exempt estimated current returns under current federal taxes using the published marginal federal tax rates currently scheduled to be in effect in 2015. This table illustrates the amount of return an investor would need in a taxable investment to earn an after-tax return equal to that of a tax-exempt investment. The table does not reflect any state or local taxes, the effect of limitations (if any) on the amount of allowable itemized deductions or credits, any alternative minimum taxes or any taxes other than federal personal income taxes. This information is based on present law as of the date of publication and does not account for any proposed changes in tax rates. See "Federal Tax Status" for a more detailed discussion of federal tax rules applicable to an investment in the Trust.

The Sponsor may from time to time in its advertising and sales materials compare the then current estimated returns on the Trusts and returns over specified periods on other similar Invesco sponsored unit investment trusts with inflation rates and with returns on taxable investments such as corporate or U.S. Government bonds, bank CDs and money market accounts or money market funds, each of which has investment characteristics that may differ from those of the Trusts. U.S. Government bonds, for example, are backed by the full faith and credit of the federal government. Money market accounts and money market funds provide stability of principal, but pay interest at rates that vary with the condition of the short-term debt market. The investment characteristics of the Trusts are described more fully in the prospectus. Estimated Cash Flows to Unitholders The table below sets forth the per Unit estimated monthly distributions of interest and principal to Unitholders. The table assumes no changes in expenses, no changes in the current interest rates, no exchanges, redemptions, sales or prepayments of the underlying bonds prior to maturity or expected retirement date and the receipt of principal upon maturity or expected retirement date. To the extent the foregoing assumptions change actual distributions will vary.
