The Proxy Statement/ Prospectus is being mailed to shareholders of the Pioneer Funds on or about August 11, 2006. The Proxy Statement/Prospectus contains information you should know before voting on the proposed Agreement and Plan of Reorganization that provides for the Reorganization of your fund into a corresponding Pioneer Fund (each, a "Reorganization"). Please read the Proxy Statement/Prospectus carefully, including Exhibit A and Exhibit B, because they are a part of this Proxy Statement/Prospectus and contain details that are not in the summary. The following table indicates (a) the corresponding Pioneer Fund shares that shareholders would receive if the Agreement and Plan of Reorganization is approved, (b) which shareholders may vote on each proposal, and (c) what page of this Proxy Statement/Prospectus the discussion regarding each proposal begins. On each proposal, all shareholders of a Pioneer Fund, regardless of the class of shares held, will vote together as a single class.

The Pioneer Fund will assume your fund's liabilities. o Shares of the corresponding Pioneer Fund will be distributed to your fund's shareholders in proportion to their holdings of the applicable class of shares of your fund on the closing date of the Reorganization (the "Closing Date"). These shares will be distributed to shareholders in proportion to the relative net asset value of their share holdings on the Closing Date. On the Closing Date, each shareholder will hold shares of the corresponding Pioneer Fund with the same aggregate net asset value as their holdings of the applicable class of shares of your fund immediately prior to the Reorganization. 2 o Your fund will be dissolved after the Closing Date. o The Reorganizations will not result in income, gain or loss being recognized for federal income tax purposes by any of the Pioneer Funds or the shareholders of the Pioneer Funds. o In recommending each of the Reorganizations, the Board of Trustees of each Pioneer Fund, including all of the Trustees who are not "interested" persons (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Pioneer Funds, Pioneer Investment Management, Inc., the Pioneer Funds' investment adviser ("Pioneer") or Pioneer Funds Distributor, Inc., the Pioneer Funds' principal underwriter and distributor ("PFD") (the "Independent Trustees") have determined that the Reorganization is in the best interest of each Pioneer Fund and will not dilute the interests of shareholders of each Pioneer Fund. The Trustees have made this determination based on factors that are discussed below and in greater detail under each proposal. Why Your Fund's Trustees Recommend the Reorganization The Trustees believe that reorganizing your fund into a similarly managed Pioneer Fund offers you potential benefits. These potential benefits and considerations include: o The opportunity to be part of a combined Pioneer Fund with greater assets that may be better positioned in the market to further increase asset size and achieve economies of scale. Economies of scale have potential benefits to the combined fund in two ways. First, a larger fund, which trades in larger blocks of securities, will be able to hold larger positions in individual securities and, consequently, have an enhanced ability to achieve better net prices on securities trades. In addition, each Pioneer Fund incurs substantial operating costs for insurance, accounting, legal, and custodial services. The combination of the Pioneer Funds resulting from the Reorganization may spread fixed expenses over a larger asset base, potentially contributing to a lower expense ratio in the long term than your fund would achieve separately. o The transaction will qualify as a tax free reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code") and therefore will not be treated as a taxable sale of your fund's shares. o In most instances, the pro forma expense ratio for each of the combined Pioneer Funds' class of shares is anticipated to be the same or lower than the historical expense ratio of the corresponding class of shares of the fund being acquired. Therefore, your fund's Trustees recommend that you vote FOR the Reorganization. What are the Federal Income Tax Consequences of the Reorganizations The Reorganizations will not result in any income, gain or loss being recognized for federal income tax purposes by any of the Pioneer Funds or their shareholders as a direct result of the Reorganizations. However, in accordance with the Pioneer Funds' policy to distribute its investment company taxable income, net tax-exempt income and net capital gains for the taxable year (in order to qualify for tax treatment as a regulated investment company and avoid federal income tax thereon at the fund level), each Pioneer Fund that is being merged into a corresponding Pioneer Fund will declare and pay a distribution of such income and gains to its shareholders shortly before the Reorganizations. Each such distribution, other than distributions of exempt-interest dividends, will be taxable to those shareholders. Additionally, following the Reorganizations, each Pioneer Fund will declare and pay before the end of 2006 a distribution of such income and gains to its shareholders. Those distributions will be fully taxable to all shareholders of the Pioneer Funds, including those of the merged Pioneer Funds, even though those distributions may include a portion of the Pioneer Fund's income and gains that were realized before the Closing Date. Who Bears the Expenses Associated with the Reorganizations Pioneer has agreed to pay 50% of the costs of preparing and printing the Proxy Statement/Prospectus and the solicitation costs incurred in connection with the Reorganizations. The Pioneer Funds will each pay an equal portion of the remaining 50% of the costs incurred in connection with the Reorganizations. What Happens if a Reorganization is Not Approved If the required approval of shareholders of a Pioneer Fund is not obtained, the meeting with respect to such Fund may be adjourned as more fully described in this Proxy Statement/Prospectus, and such Fund will continue to engage in the business as a separate mutual fund and the Board will consider what further action may be appropriate. 3 Who is Eligible to Vote? Shareholders of record on July 31, 2006 are entitled to attend and vote at the meeting or any adjourned meeting. Each share is entitled to one vote. Shares represented by properly executed proxies, unless revoked before or at the meeting, will be voted according to shareholders' instructions. If you sign a proxy but do not fill in a vote, your shares will be voted to approve the Agreement and Plan of Reorganization. If any other business comes before the meeting, your shares will be voted at the discretion of the persons named as proxies. 4 TABLE OF CONTENTS Page --- INTRODUCTION ................................................................................ 2 PROPOSAL 1(a) -- PIONEER AMERICA INCOME TRUST ............................................... 6 PROPOSAL 1(b) -- PIONEER BALANCED FUND ...................................................... 22 PROPOSAL 1(c) -- PIONEER FLORIDA TAX FREE INCOME FUND ....................................... 38 PROPOSAL 1(d) -- PIONEER FOCUSED EQUITY FUND ................................................ 53 TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION .......................................... 68 TAX STATUS OF EACH REORGANIZATION ........................................................... 69 VOTING RIGHTS AND REQUIRED VOTE ............................................................. 69 COMPARISON OF MASSACHUSETTS BUSINESS TRUST AND DELAWARE STATUTORY TRUST (Proposal 1(a) only) 70 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS .............................................. 71 FINANCIAL HIGHLIGHTS ........................................................................ 81 INFORMATION CONCERNING THE MEETING .......................................................... 97 OWNERSHIP OF SHARES OF THE PIONEER FUNDS .................................................... 98 EXPERTS ..................................................................................... 106 AVAILABLE INFORMATION ....................................................................... 106 EXHIBIT A -- FORM OF AGREEMENT AND PLAN OF REORGANIZATION ...................................

You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as Exhibit A, because they contain details that are not in the summary. If Proposal 1(a) is approved, your fund will be reorganized into Pioneer Government Income Fund, as described above. Both your fund and Pioneer Government Income Fund share a similar investment objective of seeking current income as is consistent with the preservation of capital and consequently, both funds have similar investment policies and risks. However, Pioneer Government Income Fund may invest in a broader range of U.S. government securities and derivatives, and is therefore subject to additional risks associated with such investments. The table below provides a comparison of the two funds. In the table below, if a row extends across the entire table, the policy disclosed applies to both your fund and Pioneer Government Income Fund.

Mr. Schlanger and Mr. Melchreit are supported by the fixed income team. Members of this team manage other Pioneer funds investing primarily in fixed income securities. The portfolio managers and the team also may draw upon the research and investment management expertise of the global research team, which provides fundamental research on companies and includes members from Pioneer's affiliate, Pioneer Investment Management Limited. Mr. Schlanger, a vice president, joined Pioneer as a portfolio manager in 1988 after spending 12 years with Irving Trust Company in New York, where he had overall responsibility for managing nearly $1.5 billion in fixed income assets. Mr. Melchreit, a vice president, joined Pioneer in 2006. From 2003 to 2004 Mr. Melchreit was a managing director at Cigna Investment Management. Prior thereto, he was senior vice president and portfolio manager at Aeltus Investment Management.

The fund will provide written notice to shareholders at least 60 days prior to any change to the requirement that it invest at least 80% of its assets in U.S. government securities. The fund's investments may have all types of interest rate payment and reset terms, including fixed rate, adjustable rate, zero coupon, contingent, deferred, payment-in-kind and auction rate features. The fund may invest in securities with a broad range of maturities and maintains an average portfolio maturity which varies based upon the judgment of Pioneer. In pursuing its investment strategy, Pioneer Government Income Fund may over time dispose of securities acquired through the reorganization in the ordinary course of business. This may result in Pioneer Government Income Fund realizing gains on previously existing Pioneer America Income Trust holdings, which capital gains will be distributed to all of Pioneer Government Income Fund's shareholders after the closing date, and incurring transactions costs. The amount of such gains and any transaction costs cannot be accurately estimated at this time. Pioneer intends to take such factors into consideration in selecting any portfolio positions for sale. - ------------------------------------------------------------------------------------------------------------------------------------ Each fund may invest in mortgage-backed securities issued by agencies or instrumentalities of the U.S. government. These securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real estate. Certain debt instruments may only pay principal at maturity or may only represent the right to receive payments of principal or payments of interest on underlying pools of mortgage or government securities, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. Principal only mortgage-backed securities generally increase in value if interest rates decline, but are also subject to the risk of prepayment. Interest only instruments generally increase in value in a rising interest rate environment when fewer of the underlying mortgages are prepaid. - ------------------------------------------------------------------------------------------------------------------------------------ Each fund may invest in repurchase agreements. Repurchase agreements are arrangements under which the fund purchases securities and the seller agrees to repurchase the securities - ------------------------------------------------------------------------------------------------------------------------------------ 8 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer America Income Trust Pioneer Government Income Fund - ------------------------------------------------------------------------------------------------------------------------------------ within a specific time and at a specific price. The repurchase price is generally higher than a fund's purchase price, with the difference being income to the fund. The other party's obligations under the repurchase agreement are collateralized with U.S. Treasury and/or agency obligations with a market value of not less than 100% of the obligations, valued daily. Repurchase agreements afford a fund an opportunity to earn income on temporarily available cash at low risk. However, in the event that the other party to the repurchase agreement defaults on its obligations, a fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. In addition, if a fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction. Each fund may purchase and sell securities, including GNMA certificates, on a when-issued or delayed delivery basis. These transactions arise when securities are purchased or sold by a fund with payment and delivery taking place at a fixed future date. Each fund will not earn income on these securities until delivered. Each fund may engage in these transactions when it believes they would result in a favorable price and yield for the security being purchased or sold. The market value of when-issued or delayed delivery transactions may increase or decrease as a result of changes in interest rates. These transactions involve risk of loss if the value of the underlying security changes unfavorably before the settlement date. There is also a risk that the other party to the transaction will default on its obligation to purchase or sell the security, which may result in a fund missing the opportunity to obtain a favorable price or yield elsewhere. - ------------------------------------------------------------------------------------------------------------------------------------ Investment strategies Pioneer, each fund's investment adviser, considers both broad economic factors and issuer specific factors in selecting a portfolio designed to achieve the fund's investment objective. In assessing the appropriate maturity and sector weighting of a fund's portfolio, Pioneer considers a variety of factors that are expected to influence economic activity and interest rates. These factors include fundamental economic indicators, such as the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of the U.S. dollar compared to other currencies. Once Pioneer determines the preferable portfolio characteristics, Pioneer selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issues) and sector diversification. In making portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. - ------------------------------------------------------------------------------------------------------------------------------------ 9 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer America Income Trust Pioneer Government Income Fund - ------------------------------------------------------------------------------------------------------------------------------------ Other investments The fund may use futures and options on securities, indices and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, the fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, the fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in interest rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non- hedging strategy that may be considered speculative. Even a small investment in derivatives can have a significant impact on the fund's exposure to interest rates. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments, the fund may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The fund will only invest in derivatives to the extent Pioneer believes these investments do not prevent the fund from seeking its investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Temporary defensive Normally, each fund invests substantially all of its assets to meet its investment objective. Each fund may strategies invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, each fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, a fund may not be able to achieve its investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Short-term trading Each fund usually does not trade for short-term profits. Each fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If a fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. - ------------------------------------------------------------------------------------------------------------------------------------ 10 - ------------------------------------------------------------------------------------------------------------------------------------ Classes of Shares, Fees and Expenses - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer America Income Trust Pioneer Government Income Fund - ------------------------------------------------------------------------------------------------------------------------------------ Class A sales charges The Class A shares of both funds have the same characteristics and fee structure. and fees o Class A shares are offered with initial sales charges up to 4.50% of the offering price, which is reduced or waived for large purchases and certain types of investors.

A discussion regarding the basis for the Board of Trustees' approval of the management contract is available in Pioneer America Income Trust's December 31, 2005 annual report to shareholders and in Pioneer Government Income Fund's January 31, 2006 semi-annual report to shareholders. - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer America Income Trust Pioneer Government Income Fund - ------------------------------------------------------------------------------------------------------------------------------------ Buying shares You may buy shares from any investment firm that has a sales agreement with PFD, the funds' distributor. You can buy shares at the offering price. You may use securities you own to purchase shares of the fund provided that Pioneer, in its sole discretion, determines that the securities are consistent with the fund's objective and policies and their acquisition is in the best interests of the fund. Class R shares are available to certain tax-deferred retirement plans (including 401(k) plans, employer-sponsored 403(b) plans, 457 plans, profit sharing and money purchase pension plans, defined benefit plans and non-qualified deferred compensation plans) held in plan level or omnibus accounts. Class R shares also are available to IRA rollovers from eligible retirement plans that offered one or more Class R share Pioneer funds as investment options. Class R shares are not available to non-retirement accounts, traditional or Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs, individual 403(b)s and most individual retirement accounts or retirement plans that are not subject to the Employee Retirement Income Security Act of 1974 (ERISA). Investor Class Shares have been issued in connection with the Reorganization. The fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the fund's outstanding Investor Class shares. Holders of Investor Class Shares of the fund may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the prospectus for that Class. All Investor Class shares of the fund, whenever issued, convert to Class A shares of the fund on December 10, 2006. If you have an existing non-retirement account, you may purchase shares of a fund by telephone or online. Certain IRAs also may use the telephone purchase privilege. - ------------------------------------------------------------------------------------------------------------------------------------ Minimum initial Your initial investment must be at least $1,000 for Class A, Class B or Class C shares. There is no investment minimum initial investment amount for Class R shares. Additional investments must be at least $100 for Class A shares, $500 for Class B shares or Class C shares, and there is no minimum additional investment amount for Class R shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. - ------------------------------------------------------------------------------------------------------------------------------------ 12 - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer America Income Trust Pioneer Government Income Fund - ------------------------------------------------------------------------------------------------------------------------------------ Maximum purchase Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. There amounts is no maximum purchase for Class A shares or Class R shares. These limits are applied on a per transaction basis. - ------------------------------------------------------------------------------------------------------------------------------------ Exchanging shares You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. Each fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred shares charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. An exchange generally is treated as a sale and a new purchase of shares for federal income tax purposes. The fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the fund's outstanding Investor Class shares. Holders of Investor Class Shares of the fund may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the prospectus for that Class. All Investor Class shares of a fund, whenever issued, convert to Class A shares of the fund on December 10, 2006. In connection with the Reorganization, Pioneer Government Income Fund's Class A shareholders will have the opportunity to exchange their shares for Class Y shares of Pioneer Government Income Fund at net asset value without any initial or contingent sales charge. After you establish an eligible fund account, you can exchange fund shares by telephone or online. - ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Your shares will be sold at net asset value per share next calculated after a fund receives your request in good order. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your account is an eligible IRA (tax penalties may apply). - ------------------------------------------------------------------------------------------------------------------------------------ Net asset value Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). - ------------------------------------------------------------------------------------------------------------------------------------ You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares. - ------------------------------------------------------------------------------------------------------------------------------------ Comparison of Principal Risks of Investing in the Funds Because each fund has similar investment objectives and investment strategies, the funds are subject to some of the same principal risks. You could lose money on your investment or not make as much as if you invested elsewhere if: o Interest rates go up causing the value of the fund's investments to decline. o During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the fund to reinvest in lower yielding securities. This is known as call or prepayment risk. 13 o During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration (the estimated period until the security is paid in full) and reduce the value of the security. This is known as extension risk. o Pioneer's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy prove to be incorrect. To the extent either fund invests significantly in mortgage-backed securities, its exposure to prepayment and extension risks may be greater than other investments in fixed income securities. Unlike your fund, Pioneer Government Income Fund is subject to the risks of investing in government-sponsored entities. Government sponsored entities such as the Federal Home Loan Mortgage Corporation (Freddie Mac), the Federal National Mortgage Association (FNMA) and the Federal Home Loan Banks (FHLBs), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government. The Funds' Fees and Expenses Shareholders of both funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each fund. The expenses in the tables appearing below are based on (i) for your fund, the expenses of your fund for the twelve-month period ended December 31, 2005, and (ii) for Pioneer Government Income Fund, the expenses of Pioneer Government Income Fund for the twelve-month period ended January 31, 2006. Future expenses for all share classes may be greater or less. The tables also show the pro forma expenses of the combined fund assuming the Reorganization occurred on January 31, 2006.

(2) The funds' total annual operating expenses in the table have not been reduced by any expense offset arrangements. (3) Net expenses in the table reflect the expense limitation that will be in effect upon the closing of the Reorganization, under which Pioneer has contractually agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to reduce fund expenses to 1.89% of the average daily net assets attributable to Class B shares. This expense limitation is in effect from the closing date of the Reorganization through December 1, 2007. There can be no assurance that Pioneer will extend the expense limitation beyond such time. (4) The funds' Investor Class shares, whenever issued, convert to Class A shares of the fund on December 10, 2006. Comparison of Fund Performance The bar charts show the year-by-year performance of each fund's Class A shares since inception. Class B, Class C, Class R and Investor Class shares will have different performance. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. The tables show average annual total return (before and after sales taxes) for each fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The after-tax returns shown for each fund are for Class A only; after-tax returns for other classes will vary. Past performance (before and after taxes) does not indicate future results. 16 [THE FOLLOWING DATA WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL] Pioneer America Income Trust Annual Return -- Class A Shares* (Year ended December 31) '96 2.29 '97 8.51 '98 7.78 '99 -2.53 '00 11.58 '01 5.92 '02 9.77 '03 1.47 '04 2.78 '05 1.84 - ---------- * During the period shown in the bar chart, Pioneer America Income Trust's highest quarterly return was 4.51% for the quarter ended September 30, 2001, and the lowest quarterly return was (2.07)% for the quarter ended March 31, 1996. For the period from January 1, 2006 to June 30, 2006, Pioneer America Income Trust's return was (1.68%). Pursuant to an agreement and plan of reorganization, Pioneer Government Income Fund acquired the assets and liabilities of AmSouth Government Income Fund (the predecessor fund) on September 23, 2005. In the reorganization, the predecessor fund exchanged all of its assets for shares of the fund. The predecessor fund offered classes of shares similar to the fund's Class A and Class B shares. As a result of the reorganization, the fund is the accounting successor of the predecessor fund. The performance of the Class A and Class B shares of the fund set forth in the table below includes the performance of the predecessor fund's Class A and Class B shares prior to the Reorganization, which has been restated to reflect differences in any applicable sales charges (but not differences in expenses). Class C shares were not previously offered by the predecessor fund. The performance of the fund's Class C shares is based upon the performance of the predecessor fund's Class B shares as adjusted to reflect sales charges applicable to the fund's Class C shares (but not other differences in expenses). If the performance had been adjusted to reflect all differences in expenses, the performance of the fund would be lower.

Furthermore, the after-tax returns shown are not relevant to shareholders who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns for Class B and Class C shares will vary from the after-tax returns presented for Class A shares. 18 (2) The performance of Class C shares does not reflect the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a 1% sales charge, your returns would be lower than those shown above.

CAPITALIZATION The following table sets forth the capitalization of each fund as of May 31, 2006 and the pro forma combined capitalization of the combined fund as if the Reorganization had occurred on that date. If the Reorganization is consummated, the actual exchange ratios on the Closing Date may vary from the exchange ratios indicated. This is due to changes in the market value of the portfolio securities of both funds between May 31, 2006 and the Closing Date, changes in the amount of undistributed net investment income and net realized capital gains of both funds during that period resulting from income and distributions, and changes in the accrued liabilities of both funds during the same period.

The table should not be relied upon to determine the amount of Pioneer Government Income Fund shares that will actually be received and distributed. PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION The Reorganization o The Reorganization is scheduled to occur as of the close of business on November 10, 2006, but may occur on such later date as the parties may agree in writing. Your fund will transfer all of its assets to Pioneer Government Income Fund, and Pioneer Government Income Fund will assume all of your fund's liabilities. This will result in the addition of your fund's assets to Pioneer Government Income Fund's portfolio. The net asset value of both funds will be computed as of the close of regular trading on the New York Stock Exchange on the Closing Date. o Pioneer Government Income Fund will issue to your fund Class A shares with an aggregate net asset value equal to the net assets attributable to your fund's Class A shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class A shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Pioneer Government Income Fund. o Pioneer Government Income Fund will issue to your fund Class B shares with an aggregate net asset value equal to the net assets attributable to your fund's Class B shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class B shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class B shareholders of your fund will end up as Class B shareholders of Pioneer Government Income Fund. o Pioneer Government Income Fund will issue to your fund Class C shares with an aggregate net asset value equal to the net assets attributable to your fund's Class C shares.

As a result, Class C shareholders of your fund will end up as Class C shareholders of Pioneer Government Income Fund. o Pioneer Government Income Fund will issue to your fund Class R shares with an aggregate net asset value equal to the net assets attributable to your fund's Class R shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class R shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class R shareholders of your fund will end up as Class R shareholders of Pioneer Government Income Fund. o Pioneer Government Income Fund will issue to your fund Investor Class shares with an aggregate net asset value equal to the net assets attributable to your fund's Investors Class shares. As part of the liquidation of your fund, these shares will immediately be distributed to Investor Class shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Investor Class shareholders of your fund will end up as Investor Class shareholders of Pioneer Government Income Fund. All Investor Class shares of Pioneer Government Income Fund, whenever issued, convert to Class A shares of Pioneer Government Income Fund on December 10, 2006. o After the shares are issued, your fund will be dissolved. Reasons for the Proposed Reorganization The Trustees of your fund believe that the proposed Reorganization will be advantageous to the shareholders of your fund for several reasons. The Trustees considered the following matters, among others, in approving the proposal. First, the Reorganization would eliminate confusion in the marketplace caused by having two substantially similar funds and enhancing the potential for one of the two funds to achieve growth in assets. The combined fund may be better positioned to attract assets than your fund. After the Reorganization, the combined fund's greater asset size may allow it, relative to your fund, to (i) obtain better net prices on securities trades, and (ii) reduce per share expenses as fixed expenses are shared over a larger asset base. Second, the long-term historical investment performance of each fund is similar. Although Pioneer America Income Trust's average annual total returns for the one- and five-year periods is higher, Pioneer Government Income Fund's long-term performance for the 10-year period is higher. For the one, five and 10-year periods ended December 31, 2005, Class A shares of Pioneer Government Income Fund had average annual total returns of -3.04% (one year); 3.21% (five year); and 4.75% (10 year), compared to average annual total returns of the Class A shares of Pioneer America Income Trust of -2.73% (one year); 3.36% (five year); and 4.38% (10 year), during the same periods. 20 Third, since the management fee rate is the same for both funds, there will be no increase in management fee (as a percentage of average daily net assets) as a result of the Reorganization. With the exception of Class C shares (due to its relatively small size), the historical total expenses of Pioneer Government Income Fund's shares are lower than Pioneer America Income Trust's historical expenses for its shares. In addition, it is anticipated that the pro forma expense ratio for each class of shares will be the same or lower than the historical expense ratio of Pioneer America Income Trust after the Reorganization and has the potential to decrease further with asset growth. Pioneer has agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to limit Pioneer Government Income Fund's Class B shares to 1.89% of the average daily net assets attributable to Class B shares through December 1, 2007. Although Pioneer Government Income Fund has historically not had Class R or Investor Class shares outstanding, these classes will be issued in the Reorganization, and the resulting expense ratio of each is expected to be approximately the same as the expense ratio of your fund's Class R and Investor Class shares. The Boards of both funds considered that each fund would bear equally half of all of the expenses associated with the preparation, printing and mailing of any shareholder communications, including this Proxy Statement/Prospectus, and any filings with the SEC and other governmental agencies in connection with the Reorganization. Pioneer will bear the balance of these expenses. The Boards of both funds estimate that these expenses in the aggregate will not exceed $84,500. The Boards of both funds considered that the funds' investment adviser and principal distributor would benefit from the Reorganization. For example, Pioneer might achieve cost savings from managing one larger fund compared to managing more than one fund with similar investment strategies, which would result in a decrease in the combined fund's gross expenses and a corresponding decrease in fees waived under the current expense limit agreement. The Boards believe, however, that these savings will not amount to a significant economic benefit to Pioneer or the principal distributor. The Boards of Trustees of both funds also considered that the Reorganization presents an excellent opportunity for the shareholders of each fund to become investors in a combined fund that has a larger asset size than either fund alone without the obligation to pay commissions or other transaction costs that a fund normally incurs when purchasing securities. This opportunity provides an economic benefit to both funds and their shareholders. BOARDS' EVALUATION AND RECOMMENDATION For the reasons described above, the Board of Trustees of your fund, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interest of your fund and that the interests of your fund's shareholders would not be diluted as a result of the Reorganization. Similarly, the Board of Trustees of Pioneer Series Trust IV, including the Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Government Income Fund and that the interests of Pioneer Government Income Fund's shareholders would not be diluted as a result of the Reorganization. The Trustees of your fund recommend that shareholders of your fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 21 PIONEER BALANCED FUND AND PIONEER CLASSIC BALANCED FUND PROPOSAL 1(b) SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein. You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as Exhibit A, because they contain details that are not in the summary. If Proposal 1(b) is approved, your fund will be reorganized into Pioneer Classic Balanced Fund, as described above. Each fund has substantially similar investment objectives and principal investment strategies, except that Pioneer Classic Balanced Fund's investment strategy focuses on value-oriented equity securities while your fund focuses on growth-oriented equity securities. The table below provides a comparison of the two funds. In the table below, if a row extends across the entire table, the policy disclosed applies to both your fund and Pioneer Classic Balanced Fund.

Normally, equity and debt securities each represent 35% to 65% of each fund's net assets. For purposes of each fund's investment policies, equity investments include common stocks, convertible debt and securities with common stock characteristics, such as equity interests in real estate investment trusts (REITs), exchange-traded funds (ETFs) that invest primarily in equity securities and preferred stocks. Each fund's investments in debt securities include U.S. government securities, corporate debt securities, mortgage- and asset-backed securities, short term debt securities, cash and cash equivalents. Cash and cash equivalents include cash balances, accrued interest and receivables for items such as the proceeds, not yet received, from the sale of a fund's portfolio investments. Debt securities in which each fund invests may have fixed or variable principal payments and all types of interest rate payment and reset terms, including fixed rate, adjustable rate, zero coupon, contingent, deferred, payment-in-kind and auction rate features. Each fund may invest up to 25% of its total assets in equity and debt securities of non-U.S. issuers. Each fund will not invest more than 5% of its total assets in the securities of emerging markets issuers. Each fund invests in non-U.S. securities to diversify its portfolio when they offer similar or greater potential for capital appreciation. Each fund may invest in U.S. government securities. U.S. government securities include obligations: directly issued by or supported by the full faith and credit of the U.S. government, like Treasury bills, notes and bonds and Government National Mortgage Association certificates; supported by the right of the issuer to borrow from the U.S. Treasury, like those of the Federal Home Loan Banks; supported by the discretionary authority of the U.S. government to purchase the agency's securities like those of the Federal National Mortgage Association; or supported only by the credit of the issuer itself, like the Tennessee Valley Authority. Each fund may invest in mortgage-backed and asset-backed securities. Mortgage-related securities may be issued by private companies or by agencies of the U.S. government and represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property. Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables. In pursuing its investment strategy, Pioneer Classic Balanced Fund may over time dispose of securities acquired through the reorganization in the ordinary course of business. This may result in Pioneer Classic Balanced Fund realizing gains on previously existing Pioneer Balanced Fund holdings, which capital gains will be distributed to all of Pioneer Classic Balanced Fund's shareholders after the closing date, and incurring transactions costs. The amount of such gains and any transaction costs cannot be accurately estimated at this time. Pioneer intends to take such factors into consideration in selecting any portfolio positions for sale. - ------------------------------------------------------------------------------------------------------------------------------------ 24 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Balanced Fund Pioneer Classic Balanced Fund - ------------------------------------------------------------------------------------------------------------------------------------ The fund's investments in mortgage-related securities may include mortgage derivatives and structured securities. - ------------------------------------------------------------------------------------------------------------------------------------ The fund may invest up to 20% of its net The fund may invest up to 25% of its total assets in REITs. assets in REITs. - ------------------------------------------------------------------------------------------------------------------------------------ Investment strategies In selecting equity securities, Pioneer seeks In selecting equity securities, Pioneer uses a securities selling at reasonable prices and then value approach to select the fund's holds these securities until the market values investments. Using this investment style, reflect their intrinsic values. Pioneer seeks securities selling at reasonable prices or substantial discounts to their underlying values and then holds these securities until the market values reflect their intrinsic values. - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer evaluates a security's potential value, including the attractiveness of its market valuation, based on the company's assets and prospects for earnings growth. In making that assessment, Pioneer employs due diligence and fundamental research, an evaluation of the issuer based on its financial statements and operations. Pioneer also considers a security's potential to provide a reasonable amount of income. Pioneer relies on the knowledge, experience and judgment of its staff who have access to a wide variety of research. Pioneer focuses on the quality and price of individual issuers, not on economic sector or market-timing strategies. Factors Pioneer looks for in selecting investments include: o Favorable expected returns relative to perceived risk o Above average potential for earnings and revenue growth o Low market valuations relative to earnings forecast, book value, cash flow and sales o A sustainable competitive advantage, such as a brand name, customer base, proprietary technology or economics of scale. In selecting debt securities, Pioneer considers both broad economic and issuer specific factors in selecting a portfolio designed to achieve the fund's investment objectives. In assessing the appropriate maturity, rating and sector weighting of the fund's portfolio, Pioneer considers a variety of factors that are expected to influence economic activity and interest rates. These factors include fundamental economic indicators, such as the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of the U.S. dollar compared to other currencies. Once Pioneer determines the preferable portfolio characteristics, Pioneer selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issuers), liquidity and rating, sector and issuer diversification. Pioneer also employs fundamental research and due diligence to assess an issuer's credit quality, taking into account financial condition and profitability, future capital needs, potential for change in rating, industry outlook, the competitive environment and management ability. In making portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer generally sells a portfolio security when it believes that the issuer no longer offers the potential for above average earnings and revenue growth. Pioneer makes that determination based upon the same criteria it uses to select portfolio securities. - ------------------------------------------------------------------------------------------------------------------------------------ 25 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Balanced Fund Pioneer Classic Balanced Fund - ------------------------------------------------------------------------------------------------------------------------------------ Other investments Up to 10% of each fund's total assets may be invested in debt securities rated below investment grade, including convertible debt. A debt security is investment grade if it is rated in one of the top four categories by a nationally recognized statistical rating organization or determined to be of equivalent credit quality by Pioneer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher quality debt securities. Each fund may invest in debt securities rated "D" or higher by a nationally recognized statistical rating organization. For purposes of each fund's credit quality policies, if a security receives different ratings from nationally recognized statistical rating organizations, each fund will use the rating chosen by the portfolio manager as most representative of the security's credit quality. If a rating organization changes the quality rating assigned to one or more of each fund's portfolio securities, Pioneer will consider if any action is appropriate in light of the fund's investment objective and policies. - ------------------------------------------------------------------------------------------------------------------------------------ Derivatives The funds may use futures and options on securities, indices and currencies, forward foreign currency exchange contracts and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, neither fund uses derivatives as a primary investment technique and generally limits their use to hedging. However, each fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in market prices of securities, interest rates or currency exchange rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non-hedging strategy that may be considered speculative Even a small investment in derivatives can have a significant impact on the funds' exposure to the market prices of securities, interest rates or currency exchange rates. If changes in a derivative's value do not correspond to changes in the value of the funds' other investments, the funds may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The funds will only invest in derivatives to the extent Pioneer believes these investments do not prevent the funds from seeking their investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Temporary defensive Normally, each fund invests substantially all of its assets to meet its investment objective. Each fund strategies may invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, each fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, a fund may not be able to achieve its investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Short-term trading Each fund usually does not trade for short-term profits. Each fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If the funds do a lot of trading, they may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. - ------------------------------------------------------------------------------------------------------------------------------------ 26 - ------------------------------------------------------------------------------------------------------------------------------------ Classes of Shares, Fees and Expenses - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Balanced Fund Pioneer Classic Balanced Fund - ------------------------------------------------------------------------------------------------------------------------------------ Class A sales charges The Class A shares of both funds have the same characteristics and fee structure. and fees o Class A shares are offered with initial sales charges up to 4.50% of the offering price, which is reduced or waived for large purchases and certain types of investors.

Pioneer's annual fee is equal to 0.65% of each fund's average daily net assets up to $1 billion, 0.60% of the next $4 billion and 0.55% on the assets over $5 billion. The fee is accrued daily and paid monthly. A discussion regarding the basis for the Board of Trustees' approval of the management contract is available in Pioneer Balanced Fund's December 31, 2005 annual report to shareholders and in Pioneer Classic Balanced Fund's statement of additional information, dated December 1, 2005. - ------------------------------------------------------------------------------------------------------------------------------------ 27 - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Balanced Fund Pioneer Classic Balanced Fund - ------------------------------------------------------------------------------------------------------------------------------------ Buying shares You may buy shares from any investment firm that has a sales agreement with PFD, the funds' distributor. You can buy shares at the offering price. You may use securities you own to purchase shares of the fund provided that Pioneer, in its sole discretion, determines that the securities are consistent with the fund's objective and policies and their acquisition is in the best interests of the fund. Investor Class shares have been issued in connection with the Reorganization. The fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the fund's outstanding Investor Class shares. Holders of Investor Class Shares of the fund may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the prospectus for that Class. All Investor Class shares of the fund, whenever issued, convert to Class A shares of the fund on December 10, 2006. If you have an existing non-retirement account, you may purchase shares of a fund by telephone or online. Certain IRAs also may use the telephone purchase privilege. - ------------------------------------------------------------------------------------------------------------------------------------ Minimum initial investment Your initial investment must be at least $1,000 for Class A, Class B or Class C shares. Additional investments must be at least $100 for Class A shares, $500 for Class B shares or Class C shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. - ------------------------------------------------------------------------------------------------------------------------------------ Maximum purchase amounts Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. There is no maximum purchase for Class A shares. These limits are applied on a per transaction basis. - ------------------------------------------------------------------------------------------------------------------------------------ Exchanging shares You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. Each fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred shares charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. An exchange generally is treated as a sale and a new purchase of shares for federal income tax purposes. The fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the fund's outstanding Investor Class shares. Holders of Investor Class shares of the Fund may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the prospectus for that Class. All Investor Class shares of the fund, whenever issued, convert to Class A shares of the fund on December 10, 2006. After you establish an eligible fund account, you can exchange fund shares by telephone or online. - ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Your shares will be sold at net asset value per share next calculated after a fund receives your request in good order. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your account is an eligible IRA (tax penalties may apply). - ------------------------------------------------------------------------------------------------------------------------------------ Net asset value Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). - ------------------------------------------------------------------------------------------------------------------------------------ 28 - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Balanced Fund Pioneer Classic Balanced Fund - ------------------------------------------------------------------------------------------------------------------------------------ You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares. - ------------------------------------------------------------------------------------------------------------------------------------ Comparison of Principal Risks of Investing in the Funds Because each fund has substantially similar investment objectives and investment strategies, the funds are also subject to some of the same risks. You could lose money on your investment or not make as much as if you invested elsewhere if: o The stock market goes down or performs poorly relative to other investments (this risk may be greater in the short term) o The fund's equity investments do not have the growth potential originally expected o Stocks selected for income do not achieve the same return as securities selected for capital growth o Value stocks fall out of favor with investors o The fund's assets remain undervalued or do not have the potential value originally expected Risks of debt securities. Each fund has risks associated with investing in debt securities. Each fund could underperform other investments if: o Interest rates go up causing the value of the fund's portfolio to decline o The issuer of a debt security owned by the fund defaults on its obligation to pay principal or interest or has its credit rating downgraded o During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the fund to reinvest in lower yielding securities. This is known as call or prepayment risk o During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration (the estimated period until the security is paid in full) and reduce the value of the security. This is known as extension risk o Pioneer's judgment about the attractiveness, relative value or potential appreciation of a particular sector, security or investment strategy proves to be incorrect Non-U.S. securities risks. Each fund may invest in non-U.S. securities. Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced for issuers in emerging markets or to the extent that the fund invests significantly in one region or country. These risks may include: o Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices o Many non-U.S. markets are smaller, less liquid and more volatile. In a changing market, Pioneer may not be able to sell the fund's portfolio securities at times, in amounts and at prices it considers reasonable o Adverse effect of currency exchange rates or controls on the value of the fund's investments o The economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession o Economic, political and social developments may adversely affect the securities markets o Withholding and other non-U.S. taxes may decrease the fund's return Risks of REITs. Both funds may invest in REITs but to different degrees. REITs are companies that invest primarily in real estate or real estate related loans. Investing in REITs involves unique risks. They are significantly affected by the market for real estate and are dependent upon management skills and cash flow. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. 29 Risks of mortgage- and asset-backed securities and mortgage derivatives. Certain debt instruments may only pay principal at maturity or may only represent the right to receive payments of principal or payments of interest on underlying pools of mortgage or government securities, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. Principal only instruments generally increase in value if interest rates decline, but are also subject to the risk of prepayment. Interest only instruments generally increase in value in a rising interest rate environment when fewer of the underlying mortgages are prepaid. Pioneer Balanced Fund may invest in mortgage derivatives and structured securities that have imbedded leverage features. As a result, small changes in interest or prepayment rates may cause large and sudden price movements. Mortgage derivatives can also become illiquid and hard to value in declining markets. Market segment risks. To the extent either fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to the industries in that segment, and may experience greater market fluctuation, than a fund without the same focus. For example, industries in the financial segment, such as banks, insurance companies, broker-dealers and REITs, may be sensitive to changes in interest rates and general economic activity and are subject to extensive government regulation. Industries in the technology segment, such as information technology, communications equipment, computer hardware and software, and office and scientific equipment, are subject to risks of rapidly evolving technology, short product lives, rates of corporate expenditures, falling prices and profits, competition from new market entrants, and general economic conditions. The Funds' Fees and Expenses Shareholders of both funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each fund.

(2) The funds' total annual operating expenses in the table have not been reduced by any expense offset arrangements. (3) Net expenses in the table reflect the expense limitations that will be in effect upon the closing of the Reorganization, under which Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses to 1.16%, 2.06% and 2.06% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through December 1, 2009 for Class A shares and through December 1, 2007 for Class B and Class C shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. See the statement of additional information for details regarding the expense limitation agreement. (4) The funds' Investor Class shares, whenever issued, convert to Class A shares of the fund on December 10, 2006. Comparison of Fund Performance The bar charts show the year-by-year performance of each fund's Class A shares since inception. Class B, Class C and Investor Class shares will have different performance. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. The tables show average annual total return (before and after sales taxes) for each fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The after-tax returns shown for each fund are for Class A only; after-tax returns for other classes will vary. Past performance (before and after taxes) does not indicate future results. Pioneer Balanced Fund began to invest for capital growth and current income in February 1997. Before that time, Pioneer Balanced Fund's objective was income from a portfolio of income producing bonds and stocks. 32 [THE FOLLOWING DATA WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL] Pioneer Balanced Fund Annual Return -- Class A Shares* (Year ended December 31) '96 9.89 '97 13.92 '98 1.15 '99 3.14 '00 5.38 '01 -2.88 '02 -11.20 '03 15.99 '04 4.43 '05 3.24 - ---------- * During the period shown in the bar chart, Pioneer Balanced Fund's highest quarterly return was 8.99% for the quarter ended June 30, 2003, and the lowest quarterly return was (11.66)% for the quarter ended September 30, 2002. For the period from January 1, 2006 to June 30, 2006, Pioneer Balanced Fund's return was 0.00%. Pursuant to an agreement and plan of reorganization, the Pioneer Classic Balanced Fund acquired the assets and liabilities of AmSouth Balanced Fund (the predecessor fund) on September 23, 2005. In the reorganization, the predecessor fund exchanged all of its assets for shares of the fund. The predecessor fund offered classes of shares similar to the fund's Class A and Class B shares. As a result of the Reorganization, the fund is the accounting successor of the predecessor fund. The performance of the Class A and Class B shares of the fund set forth in the table below includes the performance of the predecessor fund's Class A and Class B shares prior to the reorganization, which has been restated to reflect differences in any applicable sales charges (but not differences in expenses). Class C shares were not previously offered by the predecessor fund. The performance of the fund's Class C shares is based upon the performance of the predecessor fund's Class B shares as adjusted to reflect sales charges applicable to the fund's Class C shares (but not other differences in expenses). If the performance had been adjusted to reflect all differences in expenses, the performance of the fund would be lower.

CAPITALIZATION The following table sets forth the capitalization of each fund as of May 31, 2006 and the pro forma combined capitalization of both funds as if the Reorganization had occurred on that date. If the Reorganization is consummated, the actual exchange ratios on the Closing Date may vary from the exchange ratios indicated. This is due to changes in the market value of the portfolio securities of both funds between May 31, 2006 and the Closing Date, changes in the amount of undistributed net investment income and net realized capital gains of both funds during that period resulting from income and distributions, and changes in the accrued liabilities of both funds during the same period.

The table should not be relied upon to determine the amount of Pioneer Classic Balanced Fund shares that will actually be received and distributed. 35 PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION The Reorganization o The Reorganization is scheduled to occur as of the close of business on November 10, 2006, but may occur on such later date as the parties may agree in writing. Your fund will transfer all of its assets to Pioneer Classic Balanced Fund, and Pioneer Classic Balanced Fund will assume all of your fund's liabilities. This will result in the addition of your fund's assets to Pioneer Classic Balanced Fund's portfolio. The net asset value of both funds will be computed as of the close of regular trading on the New York Stock Exchange on the Closing Date. o Pioneer Classic Balanced Fund will issue to your fund Class A shares with an aggregate net asset value equal to the net assets attributable to your fund's Class A shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class A shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Pioneer Classic Balanced Fund. o Pioneer Classic Balanced Fund will issue to your fund Class B shares with an aggregate net asset value equal to the net assets attributable to your fund's Class B shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class B shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class B shareholders of your fund will end up as Class B shareholders of Pioneer Classic Balanced Fund. o Pioneer Classic Balanced Fund will issue to your fund Class C shares with an aggregate net asset value equal to the net assets attributable to your fund's Class C shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class C shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class C shareholders of your fund will end up as Class C shareholders of Pioneer Classic Balanced Fund. o Pioneer Classic Balanced Fund will issue to your fund Investor Class shares with an aggregate net asset value equal to the net assets attributable to your fund's Investors Class shares. As part of the liquidation of your fund, these shares will immediately be distributed to Investor Class shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Investor Class shareholders of your fund will end up as Investor Class shareholders of Pioneer Classic Balanced Fund. All Investor Class shares of Pioneer Classic Balanced Fund, whenever issued, convert to Class A shares of Pioneer Classic Balanced Fund on December 10, 2006. o After the shares are issued, your fund will be dissolved. Agreement and Plan of Reorganization The shareholders of your fund are being asked to approve the Agreement, the form of which is attached to this Proxy Statement/ Prospectus as Exhibit A and incorporated herein by this reference. The description of the Agreement contained herein, which include all the material provisions of the Agreement, is qualified in its entirety by the attached copy. Reasons for the Proposed Reorganization The Trustees of your fund believe that the proposed Reorganization will be advantageous to the shareholders of your fund for several reasons. The Trustees considered the following matters, among others, in approving the proposal. First, the Reorganization would eliminate confusion in the marketplace caused by having two substantially similar funds and enhancing the potential for one of the two funds to achieve growth in assets. The combined fund may be better positioned to attract assets than your fund. After the Reorganization, the combined fund's greater asset size may allow it, relative to your fund, to (i) obtain better net prices on securities trades, and (ii) reduce per share expenses as fixed expenses are shared over a larger asset base. Second, the long-term historical investment performance of Pioneer Classic Balanced Fund is higher than your fund. For the one, five and 10-year periods ended December 31, 2005, Class A shares of Pioneer Classic Balanced Fund had average annual total returns of -0.08% (one year); 3.92% (five year); and 7.33% (10 year), compared to average annual total returns of the Class A shares of Pioneer Balanced Fund of -1.42% (one year); 0.59% (five year); and 3.55% (10 year), during the same periods. Third, since the management fee rate is the same for both funds, there will be no increase in management fee (as a percentage of average daily net assets) as a result of the Reorganization. The historical total expenses of Pioneer Classic Balanced Fund for Class A, Class B and Class C shares are lower than Pioneer Balanced Fund's historical expenses for Class A, Class B and Class C shares. In addition, it is anticipated that the pro forma expense ratio for each class of shares will be lower than the historical expense ratio of Pioneer Balanced 36 Fund after the Reorganization and has the potential to decrease further with asset growth. Pioneer has agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to reduce Pioneer Classic Balanced Fund's expenses to 1.16%, 2.06% and 2.06% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through December 1, 2009 for Class A shares and through December 1, 2007 for Class B and Class C shares. Although Pioneer Classic Balanced Fund has historically not had Investor Class shares outstanding, this class will be issued in the Reorganization, and the resulting expense ratio is expected to be approximately the same as the expense ratio of your fund's Investor Class shares. The Boards of both funds considered that each fund would bear equally half of all of the expenses associated with the preparation, printing and mailing of any shareholder communications, including this Proxy Statement/Prospectus, and any filings with the SEC and other governmental agencies in connection with the Reorganization. Pioneer will bear the balance of these expenses. The Boards of both funds estimate that these expenses in the aggregate will not exceed $78,500. The Boards of both funds considered that the funds' investment adviser and principal distributor would benefit from the Reorganization. For example, Pioneer might achieve cost savings from managing one larger fund compared to managing more than one fund with similar investment strategies, which would result in a decrease in the combined fund's gross expenses and a corresponding decrease in fees waived under the current expense limit agreement. The Boards believe, however, that these savings will not amount to a significant economic benefit to Pioneer or the principal distributor. The Boards of Trustees of both funds also considered that the Reorganization presents an excellent opportunity for the shareholders of each fund to become investors in a combined fund that has a larger asset size than either fund alone without the obligation to pay commissions or other transaction costs that a fund normally incurs when purchasing securities. This opportunity provides an economic benefit to both funds and their shareholders. BOARDS' EVALUATION AND RECOMMENDATION For the reasons described above, the Board of Trustees of your fund, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interest of your fund and that the interests of your fund's shareholders would not be diluted as a result of the Reorganization. Similarly, the Board of Trustees of Pioneer Series Trust IV, including the Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Classic Balanced Fund and that the interests of Pioneer Classic Balanced Fund's shareholders would not be diluted as a result of the Reorganization. The Trustees of your fund recommend that shareholders of your fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 37 PIONEER FLORIDA TAX FREE INCOME FUND AND PIONEER AMT-FREE MUNICIPAL FUND PROPOSAL 1(c) SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein. You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as Exhibit A, because they contain details that are not in the summary. If Proposal 1(c) is approved, your fund will be reorganized into Pioneer AMT-Free Municipal Fund, as described above. Each fund has similar investment objectives and investment strategies. However, your fund is a non-diversified fund that invests primarily in Florida municipal securities that are exempt from Florida intangible personal property tax while Pioneer AMT-Free Municipal Fund is a diversified fund that invests in a broader range of municipal securities than your fund and its shares are not exempt from the Florida intangible personal property tax. In addition, your fund may invest in securities the income from which is a tax preference item for purposes of the federal alternative minimum tax while Pioneer AMT-Free Municipal Fund offers the benefit of avoiding income which is a tax preference item for non-corporate shareholders for purposes of the federal alternative minimum tax. The table below provides a comparison of the two funds. In the table below, if a row extends across the entire table, the policy disclosed applies to both your fund and Pioneer AMT-Free Municipal Fund.

The fund will limit its investment in municipal securities whose issuers are located in the same state to less than 25% of the fund's total assets. The fund may invest in municipal securities of any maturity, although under normal circumstances it is anticipated that the fund will generally invest in longer-term investments. Municipal securities with longer maturities are generally more volatile than other fixed income securities with shorter maturities. In pursuing its investment strategy, Pioneer AMT-Free Municipal Fund may over time dispose of securities acquired through the reorganization in the ordinary course of business. This may result in Pioneer AMT-Free Municipal Fund realizing gains on previously existing Pioneer Florida Tax Free Income Fund holdings, which capital gains will be distributed to all of Pioneer AMT-Free Municipal Fund's shareholders after the closing date, and incurring transactions costs. The amount of such gains and any transaction costs cannot be accurately estimated at this time. Pioneer intends to take such factors into consideration in selecting any portfolio positions for sale. - ------------------------------------------------------------------------------------------------------------------------------------ Each fund's investments may have fixed or variable principal payments and all types of interest rate payment and reset terms, including fixed and floating rates, inverse floating rate, zero coupon, contingent, deferred and payment in kind and auction rate features. - ------------------------------------------------------------------------------------------------------------------------------------ 40 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Investment strategies Pioneer considers both broad economic factors and issuer specific factors in selecting a portfolio designed to achieve each fund's investment objective. In assessing the appropriate maturity and rating weighting of each fund's portfolio, Pioneer considers a variety of factors that are expected to influence economic activity and interest rates. These factors include fundamental economic indicators, such as the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of the U.S. dollar compared to other currencies. Once Pioneer determines the preferable portfolio characteristics, Pioneer selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issues), liquidity and rating and issuer diversification. Pioneer also employs due diligence and fundamental research, an evaluation of the issuer based on its financial statements and operations, to assess an issuer's credit quality, taking into account financial condition, future capital needs and potential for change in rating. In making these portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff and affiliates who have access to a wide variety of research. - ------------------------------------------------------------------------------------------------------------------------------------ Other investments The fund may invest up to 20% of its net assets The fund may invest up to 20% of its net assets in in securities that are subject to regular federal securities of other investment companies, investment income tax, and which may be a preference grade commercial paper, U.S. government securities item for alternative minimum tax of individuals, U.S. or foreign bank instruments and repurchase including other investment companies, agreements. investment grade commercial paper, U.S. government securities, U.S. or foreign bank instruments and repurchase agreements. - ------------------------------------------------------------------------------------------------------------------------------------ Each fund may invest up to 10% of its net assets in inverse floating rate obligations (a type of derivative instrument). Inverse floating rate obligations represent interests in tax exempt bonds. The interest rate on inverse floating rate obligations will generally decrease as short-term interest rates increase, and increase as short-term rates decrease. Due to their leveraged structure, the sensitivity of the market value of an inverse floating rate obligation to changes in interest rates is generally greater than a comparable long term bond issued by the same municipality and with similar credit quality, redemption and maturity provisions. Inverse floating rate obligations may be volatile and involve leverage risk. Each fund may invest up to 10% of its net assets in debt securities rated below investment grade (including securities in default) or, if unrated, of equivalent quality as determined by Pioneer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher quality debt securities. - ------------------------------------------------------------------------------------------------------------------------------------ Temporary defensive Normally, each fund invests substantially all of its assets to meet its investment objective. strategies Each fund may invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, each fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, a fund may not be able to achieve its investment objective. Each fund intends to adopt a defensive strategy when Pioneer believes securities in which the fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances. - ------------------------------------------------------------------------------------------------------------------------------------ 41 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Short-term trading Each fund usually does not trade for short-term profits. Each fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If a fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. - ------------------------------------------------------------------------------------------------------------------------------------ Derivatives Each fund may use futures and options on securities, indices and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, each fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, each fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in the market prices of securities or interest rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non-hedging strategy that may be considered speculative Even a small investment in derivatives can have a significant impact on the fund's exposure to the market prices of securities or interest rates. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments, the fund may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The fund will only invest in derivatives to the extent Pioneer believes these investments do not prevent the fund from seeking its investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Classes of Shares, Fees and Expenses - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Class A sales charges The Class A shares of both funds have the same characteristics and fee structure. and fees o Class A shares are offered with initial sales charges up to 4.50% of the offering price, which is reduced or waived for large purchases and certain types of investors. At the time of your purchase, your investment firm may receive a commission from Pioneer Funds Distributor, Inc. ("PFD"), the funds' distributor, of up to 4% declining as the size of your investment increases. o There are no contingent deferred sales charges, except in certain circumstances when the initial sales charge is waived. o Class A shares are subject to distribution and service (12b-1) fees of up to 0.25% of average daily net assets. These fees are paid out of a fund's assets on an ongoing basis. Over time these fees will increase the cost of investments and may cost more than other types of sales charges. - ------------------------------------------------------------------------------------------------------------------------------------ Class B sales charges The Class B shares of both funds have the same characteristics and fee structure. and fees o Class B shares are offered without an initial sales charge, but are subject to contingent deferred sales charges of up to 4% if you sell your shares. The charge is reduced over time and is not charged after five years. Your investment firm may receive a commission from PFD, the funds' distributor, at the time of your purchase of up to 4%. o Class B shares are subject to distribution and service (12b-1) fees of up to 1% of average daily net assets. Both of these fees are paid out of a fund's assets on an ongoing basis. Over time these fees will increase the cost of investments and may cost more than other types of sales charges. - ------------------------------------------------------------------------------------------------------------------------------------ 42 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Class C sales charges The Class C shares of both funds have the same characteristics and fee structure. and fees o Class C shares are offered without an initial sales charge. o Class C shares are subject to a contingent deferred sales charge of 1% if you sell your shares within one year of purchase. Your investment firm may receive a commission from PFD at the time of your purchase of up to 1%. o Class C shares are subject to distribution and service (12b-1) fees of up to 1% of average daily net assets. These fees are paid out of a fund's assets on an ongoing basis. Over time these fees will increase the cost of investments and may cost more than other types of sales charges. - ------------------------------------------------------------------------------------------------------------------------------------ Class Y sales charges The Class Y shares of both funds have the same characteristics and fee structure. and fees o Class Y shares are offered without an initial sales charge. o Class Y shares are not subject to a contingent deferred sales charge. o Class Y shares are not subject to distribution and service (12b-1) fees. - ------------------------------------------------------------------------------------------------------------------------------------ Management fees Both funds have the same management fee structure. Pioneer's annual fee for each fund is equal to 0.50% of the fund's average daily net assets on the first $250 million, 0.45% on assets greater than $250 million to $750 million and 0.40% on assets greater than $750 million. The fee is accrued daily and paid monthly. A discussion regarding the basis for the Board of Trustees' approval of the management contract is available in the Pioneer Florida Tax Free Income Fund's statement of additional information dated December 1, 2005 and in Pioneer AMT-Free Municipal Fund's December 31, 2005 annual report to shareholders. - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Buying shares You may buy shares from any investment firm that has a sales agreement with PFD, the funds' distributor. You can buy shares at the offering price. You may use securities you own to purchase shares of the fund provided that Pioneer, in its sole discretion, determines that the securities are consistent with the fund's objective and policies and their acquisition is in the best interests of the fund. If you have an existing non-retirement account, you may purchase shares of a fund by telephone or online. Certain IRAs also may use the telephone purchase privilege. - ------------------------------------------------------------------------------------------------------------------------------------ Minimum initial Your initial investment must be at least $1,000 for Class A, Class B or Class C shares, and investment $5,000,000 for Class Y shares. Additional investments must be at least $100 for Class A shares, $500 for Class B or Class C shares, and there is no minimum initial investment amount for Class Y shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. - ------------------------------------------------------------------------------------------------------------------------------------ Maximum purchase amounts Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. There is no maximum purchase for Class A shares or Class Y shares. These limits are applied on a per transaction basis. - ------------------------------------------------------------------------------------------------------------------------------------ 43 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Florida Tax Free Income Fund Pioneer AMT-Free Municipal Fund - ------------------------------------------------------------------------------------------------------------------------------------ Exchanging shares You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. Each fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred shares charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. An exchange generally is treated as a sale and a new purchase of shares for federal income tax purposes. After you establish an eligible fund account, you can exchange fund shares by telephone or online. - ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Your shares will be sold at net asset value per share next calculated after a fund receives your request in good order. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your account is an eligible IRA (tax penalties may apply). - ------------------------------------------------------------------------------------------------------------------------------------ Net asset value Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). - ------------------------------------------------------------------------------------------------------------------------------------ You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares. - ------------------------------------------------------------------------------------------------------------------------------------ Comparison of Principal Risks of Investing in the Funds Principal risks for both funds Because each fund has similar investment objectives, investment strategies and principal investments, the funds are subject to some of the same principal risks. You could lose money on your investment or not make as much as if you invested elsewhere if: o Interest rates go up, causing the value of the fund's investments to decline o The issuer of a security owned by the fund defaults on its obligation to pay principal and/or interest or has its credit rating downgraded o New federal or state legislation adversely affects the tax-exempt status of securities held by the fund or the financial ability of municipalities to repay these obligations o The issuer of a security owned by the fund may not be able to make timely payments because of a general economic downturn or increased governmental costs o Pioneer is incorrect in its expectation of changes in interest rates or the credit quality of an issuer Although distributions of interest income from each fund's tax-exempt securities are generally exempt from regular federal income tax, distributions from other sources, including capital gain distributions and any gain on the sale of your shares, are not. You should consult a tax adviser about state and local taxes on your fund's distributions. Market segment risks. To the extent either fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to the industries in that segment, and may experience greater market fluctuation, than a fund without the same focus. At times, more than 25% of the Pioneer AMT-Free Municipal Fund's assets may be invested in the same market segment. 44 Principal risks of investing in Pioneer Florida Tax Free Income Fund Concentration risk. Because Pioneer Florida Tax Free Income Fund concentrates its investments in a single state, there may be more fluctuation in the value of its securities than is the case for mutual funds whose portfolios are more geographically diverse. Because the fund invests primarily in securities issued by Florida and its municipalities, it is more vulnerable to unfavorable developments in Florida than are funds that invest in municipal securities of many states. Unfavorable developments in any economic sector may adversely affect the overall Florida municipal market. Non-diversification risk. Pioneer Florida Tax Free Income Fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the fund's losses from adverse events affecting a particular issuer. Pioneer Florida Tax Free Income Fund generally invests in a limited number of securities and, as a result, the fund's performance may be more volatile than the performance of funds holding more securities. The Funds' Fees and Expenses Shareholders of both funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each fund.

This expense limitation is in effect from the closing date of the Reorganization through May 1, 2008. There can be no assurance that Pioneer will extend the expense limitation beyond such time. Comparison of Fund Performance The bar charts show the year-by-year performance of each fund's Class A shares since inception. Class B, Class C, Class Y and Investor Class shares will have different performance. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. The tables show average annual total return (before and after sales taxes) for each fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The after-tax returns shown for each fund are for Class A only; after-tax returns for other classes will vary. Past performance (before and after taxes) does not indicate future results. 47 Pursuant to an agreement and plan of reorganization, Pioneer Florida Tax Free Income Fund acquired the assets and liabilities of AmSouth Florida Tax-Exempt Fund (the predecessor fund) on September 23, 2005. In the reorganization, the predecessor fund exchanged all of its assets for shares of the fund. The predecessor fund offered classes of shares similar to the fund's Class A, Class B and Class Y shares. As a result of the reorganization, the fund is the accounting successor of the predecessor fund. The performance of the Class A, Class B and Class Y shares of the fund includes the performance of the predecessor fund's Class A, Class B and Class I shares prior to the Reorganization, which has been restated to reflect differences in any applicable sales charges (but not differences in expenses). Class C shares were not previously offered by the predecessor fund. The performance of the fund's Class C shares set forth in the table below is based upon the performance of the predecessor fund's Class B shares as adjusted to reflect sales charges applicable to the fund's Class C shares (but not other differences in expenses). If the performance had been adjusted to reflect all differences in expenses, the performance of the fund would be lower.

Pioneer AMT-Free Municipal Fund acquired the assets and liabilities of Safeco Municipal Bond Fund (the predecessor fund) on December 10, 2004. In the reorganization, the predecessor fund exchanged its assets for Investor Class shares of the fund. As a result of the reorganization, the fund is the accounting successor of the predecessor fund. The fund's Investor Class shares are not offered through this prospectus.

CAPITALIZATION The following table sets forth the capitalization of each fund as of May 31, 2006 and the pro forma combined capitalization of both funds as if the Reorganization had occurred on that date. If the Reorganization is consummated, the actual exchange ratios on the Closing Date may vary from the exchange ratios indicated. This is due to changes in the market value of the portfolio securities of both funds between May 31, 2006 and the Closing Date, changes in the amount of undistributed net investment income and net realized capital gains of both funds during that period resulting from income and distributions, and changes in the accrued liabilities of both funds during the same period.

Your fund will transfer all of its assets to Pioneer AMT-Free Municipal Fund, and Pioneer AMT-Free Municipal Fund will assume all of your fund's liabilities. This will result in the addition of your fund's assets to Pioneer AMT-Free Municipal Fund's portfolio. The net asset value of both funds will be computed as of the close of regular trading on the New York Stock Exchange on the Closing Date. o Pioneer AMT-Free Municipal Fund will issue to your fund Class A shares with an aggregate net asset value equal to the net assets attributable to your fund's Class A shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class A shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Pioneer AMT-Free Municipal Fund. o Pioneer AMT-Free Municipal Fund will issue to your fund Class B shares with an aggregate net asset value equal to the net assets attributable to your fund's Class B shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class B shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class B shareholders of your fund will end up as Class B shareholders of Pioneer AMT-Free Municipal Fund. o Pioneer AMT-Free Municipal Fund will issue to your fund Class C shares with an aggregate net asset value equal to the net assets attributable to your fund's Class C shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class C shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class C shareholders of your fund will end up as Class C shareholders of Pioneer AMT-Free Municipal Fund. o Pioneer AMT-Free Municipal Fund will issue to your fund Class Y shares with an aggregate net asset value equal to the net assets attributable to your fund's Class Y shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class Y shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class Y shareholders of your fund will end up as Class Y shareholders of Pioneer AMT-Free Municipal Fund. o After the shares are issued, your fund will be dissolved. Agreement and Plan of Reorganization The shareholders of your fund are being asked to approve the Agreement, the form of which is attached to this Proxy Statement/Prospectus as Exhibit A and incorporated herein by this reference. The description of the Agreement contained herein, which include all the material provisions of the Agreement, is qualified in its entirety by the attached copy. Reasons for the Proposed Reorganization The Trustees of your fund believe that the proposed Reorganization will be advantageous to the shareholders of your fund for several reasons. The Trustees considered the following matters, among others, in approving the proposal. First, the Reorganization would eliminate confusion in the marketplace caused by having two substantially similar funds and enhancing the potential for one of the two funds to achieve growth in assets. The combined fund may be better positioned to attract assets than your fund. After the Reorganization, the combined fund's greater asset size may allow it, relative to your fund, to (i) obtain better net prices on securities trades, and (ii) reduce per share expenses as fixed expenses are shared over a larger asset base. Second, the long-term historical investment performance of Pioneer AMT-Free Municipal Fund is higher than your fund. For the one and five year periods ended December 31, 2005, Class A shares of Pioneer AMT-Free Municipal Fund had average annual total returns of 0.07% (one year) and 5.17% (five year), compared to average annual total returns of the Class A shares of Pioneer Florida Tax Free Income Fund of -3.59% (one year) and 2.66% (five year), during the same periods. Third, since the management fee rate is the same for both funds, there will be no increase in management fee (as a percentage of average daily net assets) as a result of the Reorganization. The Reorganization would however result in Pioneer AMT-Free Municipal Fund's assets exceeding the second breakpoint level ($500 million) in the fund's management fee schedule. If assets were to continue to grow the effective rate of the combined fund's management fee will be reduced as a result. With the exception of Class A shares, the historical total expenses of Pioneer AMT-Free Municipal Fund's shares are lower than Pioneer Florida Tax Free Income Fund's historical total expenses for its shares. In addition, it is anticipated that the pro forma expense ratio for each class of shares will be the same or lower than the 51 historical expense ratio of Pioneer Florida Tax Free Income Fund after the Reorganization and has the potential to decrease further with asset growth. Pioneer has agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to limit Pioneer AMT-Free Municipal Fund's Class A shares to 0.82% of the average daily net assets attributable to Class A shares through May 1, 2008. Fourth, the Board was presented with information and considered that Pioneer AMT-Free Municipal Fund's shares are not exempt from the Florida state intangible personal property tax. However, the Board also considered the fact that Pioneer AMT-Free Municipal Fund offers the benefit of not investing in any securities the income from which is a preference item for purposes of the alternative minimum tax, whereas Pioneer Florida Tax Free Income Fund may invest up to 20% of its assets in such securities. The Boards of both funds considered that each fund would bear equally half of all of the expenses associated with the preparation, printing and mailing of any shareholder communications, including this Proxy Statement/Prospectus, and any filings with the SEC and other governmental agencies in connection with the Reorganization. Pioneer will bear the balance of these expenses. The Boards of both funds estimate that these expenses in the aggregate will not exceed $46,500. The Boards of both funds considered that the funds' investment adviser and principal distributor would benefit from the Reorganization. For example, Pioneer might achieve cost savings from managing one larger fund compared to managing more than one fund with similar investment strategies, which would result in a decrease in the combined fund's gross expenses and a corresponding decrease in fees waived under the current expense limit agreement. The Boards believe, however, that these savings will not amount to a significant economic benefit to Pioneer or the principal distributor. The Boards of Trustees of both funds also considered that the Reorganization presents an excellent opportunity for the shareholders of each fund to become investors in a combined fund that has a larger asset size than either fund alone without the obligation to pay commissions or other transaction costs that a fund normally incurs when purchasing securities. This opportunity provides an economic benefit to both funds and their shareholders. BOARDS' EVALUATION AND RECOMMENDATION For the reasons described above, the Board of Trustees of your fund, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interest of your fund and that the interests of your fund's shareholders would not be diluted as a result of the Reorganization. Similarly, the Board of Trustees of Pioneer Series Trust II, including the Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer AMT-Free Municipal Fund and that the interests of Pioneer AMT-Free Municipal Fund's shareholders would not be diluted as a result of the Reorganization. The Trustees of your fund recommend that shareholders of your fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 52 PIONEER FOCUSED EQUITY FUND AND PIONEER RESEARCH FUND PROPOSAL 1(d) SUMMARY The following is a summary of more complete information appearing later in this Proxy Statement/Prospectus or incorporated herein. You should read carefully the entire Proxy Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as Exhibit A, because they contain details that are not in the summary. If Proposal 1(d) is approved, your fund will be reorganized into Pioneer Research Fund, as described above. Although each fund has the same investment objective, your fund is a non-diversified fund that may invest a significant portion of its assets in equity securities of mid- and large-cap companies, as well as a greater portion of its assets in non-U.S. securities, than Pioneer Research Fund. Pioneer Research Fund is a diversified fund that invests primarily in equity securities of U.S. issuers. The table below provides a comparison of the two funds.

Each strategies fund may invest the remainder of its assets in securities with remaining maturities of less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, each fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, a fund may not be able to achieve its investment objective. Each fund intends to adopt a defensive strategy when Pioneer (or the subadviser, as the case may be) believes securities in which the fund normally invests have extraordinary risks due to political or economic factors and in other extraordinary circumstances. - ------------------------------------------------------------------------------------------------------------------------------------ Short-term trading Each fund usually does not trade for short-term profits. Each fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If a fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. - ------------------------------------------------------------------------------------------------------------------------------------ 56 - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Focused Equity Fund Pioneer Research Fund - ------------------------------------------------------------------------------------------------------------------------------------ Derivatives Each fund may use futures and options on securities, indices and currencies, forward foreign currency exchange contracts and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Although there is no specific limitation on investing in derivatives, each fund does not use derivatives as a primary investment technique and generally limits their use to hedging. However, each fund may use derivatives for a variety of non-principal purposes, including: o As a hedge against adverse changes in market prices of securities, interest rates or currency exchange rates o As a substitute for purchasing or selling securities o To increase the fund's return as a non-hedging strategy that may be considered speculative Even a small investment in derivatives can have a significant impact on the funds' exposure to the market prices of securities, interest rates or currency exchange rates. If changes in a derivative's value do not correspond to changes in the value of the funds' other investments, the funds may not fully benefit from or could lose money on the derivative position. In addition, some derivatives involve risk of loss if the person who issued the derivative defaults on its obligation. Certain derivatives may be less liquid and more difficult to value. The funds will only invest in derivatives to the extent Pioneer (or the subadviser, as the case may be) believes these investments do not prevent the funds from seeking their investment objective. - ------------------------------------------------------------------------------------------------------------------------------------ Classes of Shares,Fees and Expenses - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Focused Equity Fund Pioneer Research Fund - ------------------------------------------------------------------------------------------------------------------------------------ Class A sales charges The Class A shares of both funds have the same characteristics and fee structure. and fees o Class A shares are offered with initial sales charges up to 5.75% of the offering price, which is reduced or waived for large purchases and certain types of investors.

Certain IRAs also may use the telephone purchase privilege. - ------------------------------------------------------------------------------------------------------------------------------------ Minimum initial Your initial investment must be at least $1,000 for Class A, Class B or Class C shares, and investment $5,000,000 for Class Y shares. Additional investments must be at least $100 for Class A shares, $500 for Class B or Class C shares, and there is no minimum initial investment amount for Class Y shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. - ------------------------------------------------------------------------------------------------------------------------------------ Maximum purchase Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. There amounts is no maximum purchase for Class A shares or Class Y shares. These limits are applied on a per transaction basis. - ------------------------------------------------------------------------------------------------------------------------------------ 58 - ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares - ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Focused Equity Fund Pioneer Research Fund - ------------------------------------------------------------------------------------------------------------------------------------ Exchanging shares You may exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. Each fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred shares charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. An exchange generally is treated as a sale and a new purchase of shares for federal income tax purposes. After you establish an eligible fund account, you can exchange fund shares by telephone or online. - ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Your shares will be sold at net asset value per share next calculated after a fund receives your request in good order. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your account is an eligible IRA (tax penalties may apply). - ------------------------------------------------------------------------------------------------------------------------------------ Net asset value Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). - ------------------------------------------------------------------------------------------------------------------------------------ You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares. - ------------------------------------------------------------------------------------------------------------------------------------ Comparison of Principal Risks of Investing in the Funds Because each fund has the same investment objective and similar investment policies and strategies, the funds are subject to some of the same principal risks. You could lose money on your investment or not make as much as if you invested elsewhere if: o The stock market goes down or performs poorly relative to other investments (this risk may be greater in the short term) o Value stocks fall out of favor with investors o Pioneer Focused Equity Fund does not have the growth potential originally expected o Pioneer Research Fund's investments remain undervalued or do not have the potential value originally expected Market segment risks. To the extent either fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to the industries in that segment, and may experience greater market fluctuation, than a fund without the same focus. For example, industries in the financial segment, such as banks, insurance companies, broker-dealers and REITs, may be sensitive to changes in interest rates and general economic activity and are subject to extensive government regulation. Industries in the technology segment, such as information technology, communications equipment, computer hardware and software, and office and scientific equipment, are subject to risks of rapidly evolving technology, short product lives, rates of corporate expenditures, falling prices and profits, competition from new market entrants, and general economic conditions. Non-U.S. securities risks. Each fund is also subject to risks associated with investments other than U.S. equity securities. Pioneer Focused Equity Fund may invest in non-U.S. securities to a greater degree than Pioneer Research Fund. Investing in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. Some of these risks do not apply to larger, more developed non-U.S. countries. However, these risks are more pronounced for issuers of securities in emerging markets. These risks may include: o Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices 59 o Many non-U.S. markets are smaller, less liquid and more volatile. In a changing market, Pioneer may not be able to sell the fund's portfolio securities at times, in amounts and at prices it considers reasonable o Adverse effect of currency exchange rates or controls on the value of the fund's investments o The economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession o Economic, political and social developments may adversely affect the securities markets o Withholding and other non-U.S. taxes may decrease the fund's return Non-diversification risk (Pioneer Focused Equity Fund). Pioneer Focused Equity Fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the fund's losses from adverse events affecting a particular issuer. The fund generally invests in a limited number of securities and, as a result, the fund's performance may be more volatile than the performance of funds holding more securities. The Funds' Fees and Expenses Shareholders of both funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each fund. The expenses in the tables appearing below are based on (i) for your fund, the expenses of your fund for the twelve-month period ended January 31, 2006, and (ii) for Pioneer Research Fund, the expenses of Pioneer Research Fund for the twelve-month period ended December 31, 2005. Future expenses for all share classes may be greater or less. The tables also show the pro forma expenses of the combined fund assuming the Reorganization occurred on December 31, 2005.

(3) The expenses in the table above reflect the expense limitations currently in effect under which Pioneer has contractually agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to reduce fund expenses to 1.25%, 2.15% and 2.15% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through May 1, 2009 for Class A shares and through May 1, 2007 for Class B and Class C shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. (4) Net expenses in the table reflect the expense limitations that will be in effect upon the closing of the Reorganization, under which Pioneer has contractually agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to reduce fund expenses to 1.25%, 2.15% and 2.15% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect from the closing date of the Reorganization through May 1, 2009 for Class A shares and through May 1, 2008 for Class B and Class C shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Comparison of Fund Performance The bar charts show the year-by-year performance of each fund's Class A shares since inception. Class B, Class C and Class Y shares will have different performance. The chart does not reflect any sales charge you may pay when you buy or sell fund shares. Any sales charge will reduce your return. The tables show average annual total return (before and after sales taxes) for each fund over time for each class of shares (including deductions for sales charges) compared with a broad-based securities market index. The after-tax returns shown for each fund are for Class A only; after-tax returns for other classes will vary. Past performance (before and after taxes) does not indicate future results. Pursuant to an agreement and plan of reorganization, Pioneer Focused Equity Fund acquired the assets and liabilities of AmSouth Select Equity Fund (the predecessor fund) on September 23, 2005. In the reorganization, the predecessor fund exchanged all of its assets for shares of the fund. The predecessor fund offered classes of shares similar to the fund's Class A, Class B and Class Y shares. As a result of the reorganization, the fund is the accounting successor of the predecessor fund. The performance of the Class A, Class B and 62 Class Y shares of the fund includes the performance of the predecessor fund's Class A, Class B and Class I shares prior to the Reorganization, which has been restated to reflect differences in any applicable sales charges (but not differences in expenses). Class C shares were not previously offered by the predecessor fund. The performance of the fund's Class C shares set forth in the table below is based upon the performance of the predecessor fund's Class B shares as adjusted to reflect sales charges applicable to the fund's Class C shares (but not other differences in expenses). If the performance had been adjusted to reflect all differences in expenses, the performance of the fund would be lower.

If the Reorganization is consummated, the actual exchange ratios on the Closing Date may vary from the exchange ratios indicated. This is due to changes in the market value of the portfolio securities of both funds between May 31, 2006 and the Closing Date, changes in the amount of undistributed net investment income and net realized capital gains of both funds during that period resulting from income and distributions, and changes in the accrued liabilities of both funds during the same period.

The table should not be relied upon to determine the amount of Pioneer Research Fund shares that will actually be received and distributed. PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION The Reorganization o The Reorganization is scheduled to occur as of the close of business on November 10, 2006, but may occur on such later date as the parties may agree in writing. Your fund will transfer all of its assets to Pioneer Research Fund, and Pioneer Research Fund will assume all of your fund's liabilities. This will result in the addition of your fund's assets to Pioneer Research Fund's portfolio. The net asset value of both funds will be computed as of the close of regular trading on the New York Stock Exchange on the Closing Date. o Pioneer Research Fund will issue to your fund Class A shares with an aggregate net asset value equal to the net assets attributable to your fund's Class A shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class A shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class A shareholders of your fund will end up as Class A shareholders of Pioneer Research Fund. o Pioneer Research Fund will issue to your fund Class B shares with an aggregate net asset value equal to the net assets attributable to your fund's Class B shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class B shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class B shareholders of your fund will end up as Class B shareholders of Pioneer Research Fund. o Pioneer Research Fund will issue to your fund Class C shares with an aggregate net asset value equal to the net assets attributable to your fund's Class C shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class C shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class C shareholders of your fund will end up as Class C shareholders of Pioneer Research Fund. 65 o Pioneer Research Fund will issue to your fund Class Y shares with an aggregate net asset value equal to the net assets attributable to your fund's Class Y shares. As part of the liquidation of your fund, these shares will immediately be distributed to Class Y shareholders of record of your fund in proportion to their holdings on the Closing Date. As a result, Class Y shareholders of your fund will end up as Class Y shareholders of Pioneer Research Fund. o After the shares are issued, your fund will be dissolved. Agreement and Plan of Reorganization The shareholders of your fund are being asked to approve the Agreement and Plan of Reorganization, the form of which is attached to this Proxy Statement/Prospectus as Exhibit A and incorporated herein by this reference. The description of the Agreement and Plan of Reorganization contained herein, which include all the material provisions of the Agreement and Plan of Reorganization, is qualified in its entirety by the attached copy. Reasons for the Proposed Reorganization The Trustees of your fund believe that the proposed Reorganization will be advantageous to the shareholders of your fund for several reasons. The Trustees considered the following matters, among others, in approving the proposal. First, the Reorganization would eliminate confusion in the marketplace caused by having two substantially similar funds and enhancing the potential for one of the two funds to achieve growth in assets. The combined fund may be better positioned to attract assets than your fund. After the Reorganization, the combined fund's greater asset size may allow it, relative to your fund, to (i) obtain better net prices on securities trades, and (ii) reduce per share expenses as fixed expenses are shared over a larger asset base. Second, while Pioneer Research Fund's longer term performance was lower than your fund's performance, Pioneer Research Fund's Class A shares had higher total returns than your fund during the two most recent calendar years. For the one and five year periods ended December 31, 2005, Class A shares of Pioneer Research Fund had average annual total returns of 1.03% (one year) and -1.34% (five year), compared to average annual total returns of the Class A shares of Pioneer Focused Equity Fund of -12.06% (one year) and 3.54% (five year), during the same periods. Third, although your fund's management fee rate schedule is lower than that of Pioneer Research Fund, Pioneer has agreed to reduce its management fee rate upon the closing of the Reorganization for Pioneer Research Fund to equal your fund's management fee rate. Although the total expenses of your fund's shares are generally lower than Pioneer Research Fund's shares total expenses, Pioneer has agreed not to impose all or a portion of its management fee and, if necessary, to limit other ordinary operating expenses to the extent required to reduce Pioneer Research Fund's expenses to 1.25%, 2.15% and 2.15% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through May 1, 2009 for Class A shares and through May 1, 2008 for Class B and Class C shares. Further, the pro forma Class Y share expense ratio of the combined fund is expected to be lower than the Class Y share expense ratio of your fund. The Boards of both funds considered that each fund would bear equally half of all of the expenses of the funds associated with the preparation, printing and mailing of any shareholder communications, including this Proxy Statement/Prospectus, and any filings with the SEC and other governmental agencies in connection with the Reorganization. Pioneer will bear the balance of these expenses. The Boards of both funds estimate that these expenses in the aggregate will not exceed $57,500. The Boards of both funds considered that the funds' investment adviser and principal distributor would benefit from the Reorganization. For example, Pioneer might achieve cost savings from managing one larger fund compared to managing more than one fund with similar investment strategies, which would result in a decrease in the combined fund's gross expenses and a corresponding decrease in fees waived under the current expense limit agreement. The Boards believe, however, that these savings will not amount to a significant economic benefit to Pioneer or the principal distributor. The Boards of Trustees of both funds also considered that the Reorganization presents an excellent opportunity for the shareholders of each fund to become investors in a combined fund that has a larger asset size than either fund alone without the obligation to pay commissions or other transaction costs that a fund normally incurs when purchasing securities. This opportunity provides an economic benefit to both funds and their shareholders. 66 BOARDS' EVALUATION AND RECOMMENDATION For the reasons described above, the Board of Trustees of your fund, including the Independent Trustees, approved the Reorganization. In particular, the Trustees determined that the Reorganization is in the best interest of your fund and that the interests of your fund's shareholders would not be diluted as a result of the Reorganization. Similarly, the Board of Trustees of Pioneer Research Fund, including the Independent Trustees, approved the Reorganization. They also determined that the Reorganization is in the best interests of Pioneer Research Fund and that the interests of Pioneer Research Fund's shareholders would not be diluted as a result of the Reorganization. The Trustees of your fund recommend that shareholders of your fund vote FOR the proposal to approve the Agreement and Plan of Reorganization. 67 TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION The Reorganizations o Each Reorganization is scheduled to occur as of the close of business on November 10, 2006, but may occur on such later date as the parties may agree to in writing. Your fund will transfer all of its assets to the corresponding Pioneer Fund. The corresponding Pioneer Fund will assume all of your fund's liabilities. The net asset value of both funds will be computed as of the close of regular trading on the New York Stock Exchange on the reorganization date. o The corresponding Pioneer Fund will issue classes of shares to your fund with an aggregate net asset value equal to the net assets attributable to your fund's corresponding classes of shares. These shares will immediately be distributed to your fund's shareholders in proportion to the relative net asset value of their holdings of your fund's shares on the Closing Date. As a result, your fund's shareholders will end up as shareholders of the relevant class of the corresponding Pioneer Fund. o After the shares are issued, your fund will be dissolved. o Each Reorganization is intended to result in no income, gain or loss for federal income tax purposes to the corresponding Pioneer Fund, your fund or the shareholders of your fund and will not take place unless both Pioneer Funds involved in the Reorganization receive a satisfactory opinion concerning the tax consequences of the Reorganization from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Pioneer Funds. Agreement and Plan of Reorganization The shareholders of your fund are being asked to approve an Agreement and Plan of Reorganization, the form of which is attached as Exhibit A to this Proxy Statement/Prospectus and incorporated herein by this reference. The description of the Agreement and Plan of Reorganization contained herein, which includes the material provisions of the Agreement and Plan of Reorganization, is qualified in its entirety by the attached copy. Cancellation of Share Certificates. If your shares are represented by one or more share certificates before the Closing Date, on the Closing Date all certificates will be canceled, will no longer evidence ownership of your fund's shares and will evidence ownership of the corresponding Pioneer Fund shares. The corresponding Pioneer Fund will not issue share certificates in the Reorganization. Conditions to Closing the Reorganization. The obligation of your fund to consummate the Reorganization is subject to the satisfaction of certain conditions, including the performance by the corresponding Pioneer Fund of all its obligations under the Agreement and Plan of Reorganization and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Agreement and Plan of Reorganization, Section 6). The obligation of the corresponding Pioneer Fund to consummate the Reorganization is subject to the satisfaction of certain conditions, including your fund's performance of all of its obligations under the Agreement and Plan of Reorganization, the receipt of certain documents and financial statements from your fund and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Agreement and Plan of Reorganization, Section 7). The obligations of your fund and the corresponding Pioneer Fund are subject to approval of the Agreement and Plan of Reorganization by the necessary vote of the outstanding shares of your fund in accordance with the provisions of your fund's declaration of trust and by-laws. The funds' obligations are also subject to the receipt of a favorable opinion of Wilmer Cutler Pickering Hale and Dorr LLP as to the federal income tax consequences of the Reorganization (see Agreement and Plan of Reorganization, Section 8.5). Termination of Agreement and Plan of Reorganization. The Board of Trustees of your fund or the corresponding Pioneer Fund may terminate the Agreement and Plan of Reorganization (even if the shareholders of your fund have already approved it) by their mutual agreement at any time before the Closing Date, if the Boards believe that proceeding with the Reorganization would no longer be advisable. Expenses of the Reorganization. The funds will bear equally half of all the expenses of both funds incurred in connection with the Reorganization, including the costs of printing, mailing, legal fees, audit fees and solicitation expenses. Pioneer will bear the balance of these expenses. 68 TAX STATUS OF EACH REORGANIZATION Each Reorganization will not result in income, gain or loss for U.S. federal income tax purposes and will not take place unless the funds receive a satisfactory opinion from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the funds, that the Reorganization will be a "reorganization" within the meaning of Section 368(a) of the Code. As a result, for federal income tax purposes: o No gain or loss will be recognized by your fund upon (1) the transfer of all of its assets to the corresponding Pioneer Fund as described above or (2) the distribution by your fund of the corresponding Pioneer Fund shares to your fund's shareholders; o No gain or loss will be recognized by the corresponding Pioneer Fund upon the receipt of your fund's assets solely in exchange for the issuance of the corresponding Pioneer Fund shares to your fund and the assumption of your fund's liabilities by the corresponding Pioneer Fund; o The basis of the assets of your fund acquired by the corresponding Pioneer Fund will be the same as the basis of those assets in the hands of your fund immediately before the transfer; o The tax holding period of the assets of your fund in the hands of the corresponding Pioneer Fund will include your fund's tax holding period for those assets; o You will not recognize gain or loss upon the exchange of your shares of your fund solely for the corresponding Pioneer Fund shares as part of the Reorganization; o The basis of the corresponding Pioneer Fund shares received by you in the Reorganization will be the same as the basis of the shares of your fund you surrender in exchange; and o The tax holding period of the corresponding Pioneer Fund shares you receive will include the tax holding period of the shares of your fund that you surrender in exchange, provided that the shares of your fund were held by you as capital assets on the date of the exchange. In rendering such opinion, counsel shall rely upon, among other things, reasonable assumptions as well as representations of the corresponding Pioneer Fund and your fund. No tax ruling has been or will be received from the Internal Revenue Service ("IRS") in connection with the Reorganization. An opinion of counsel is not binding on the IRS or a court, and no assurance can be given that the IRS would not assert, or a court would not sustain, a contrary position. The foregoing consequences may not apply to certain classes of taxpayers who are subject to special circumstances, such as shareholders who are not citizens of or residents of the United States, insurance companies, tax-exempt organizations, financial institutions, dealers in securities or foreign currencies, or persons who hold their shares as part of a straddle or conversion transaction. You should consult your tax adviser for the particular tax consequences to you of the transaction, including the applicability of any state, local or foreign tax laws. VOTING RIGHTS AND REQUIRED VOTE Each share of your fund is entitled to one vote. A quorum is required to conduct business at the meeting. With respect to your fund, the presence in person or by proxy of a majority of the shares entitled to cast votes at the meeting will constitute a quorum. A favorable vote of a "majority of the outstanding voting securities" of your fund is required to approve the proposal with respect to your fund. For this purpose, a "majority of the outstanding shares of your fund" means the affirmative vote of the lesser of: (1) 67% or more of the shares of your fund present at the meeting, if the holders of more than 50% of the outstanding shares of your fund entitled to vote are present or represented by proxy, or (2) more than 50% of the outstanding shares of your fund. 69 The table below shows how shares will be treated for the purposes of quorum and voting requirements. - ------------------------------------------------------------------------------------------------------------------------------------ Shares Quorum Voting - ------------------------------------------------------------------------------------------------------------------------------------ In General All shares "present" in person or by proxy are Shares "present" in person will be voted in counted toward a quorum. person at the meeting.

COMPARISON OF MASSACHUSETTS BUSINESS TRUST AND DELAWARE STATUTORY TRUST As described in Proposal 1(a), it is proposed that Pioneer America Income Trust be reorganized into Pioneer Government Income Fund. Pioneer America Income Trust is a Massachusetts business trust. Pioneer Government Income Fund, like all of the other Pioneer Funds described in this Proxy Statement/Prospectus, is a Delaware statutory trust (or series thereof). The following is a summary of the principal differences between Massachusetts business trusts and Delaware statutory trusts. Limitation of Shareholders' and Series' Liability Delaware law provides that the shareholders of a Delaware statutory trust shall not be subject to liability for the debts or obligations of the trust. Under Massachusetts law, shareholders of a Massachusetts business trust may, under certain circumstances, be liability for the debts and obligations of that trust. Although the risk of liability of shareholders of a Massachusetts business trust who do not participate in the management of the trust may be remote, Delaware law affords grater protection against potential shareholder liability. Similarly, Delaware law provides that, to the extent that a Delaware statutory trust issues multiple series of shares, each series shall not be liable for the debts or obligations of any other series, another potential, although remote, risk in the case of a Massachusetts business trust. While the trustees believe that a series of a Massachusetts business trust will only be liable for its own obligations, there is no direct statutory or judicial support for that position. Limitation of Trustee Liability Delaware law provides that, except to the extent otherwise provided in a trust's declaration of trust or by-laws, trustees will not be personally liable to any person (other than the statutory trust or a shareholder thereof) for any act, omission or obligation of the statutory trust or any trustee thereof. Delaware law also provides that a trustee's actions under a Delaware statutory trust's declaration of trust or by-laws will not subject the trustee to liability to the statutory trust or its shareholders if the trustee takes such action in good faith reliance on the provisions of the statutory trust's declaration of trust or bylaws. The declaration of trust of a Massachusetts business trust may limit the liability of a trustee, who is not also an officer of the corporation, for breach of fiduciary duty except for, among other things, any act or omission not in good faith which involves intentional misconduct or a knowing violation of law or any transaction from which such trustee derives an improper direct or indirect financial benefit. The trustees believe that such limitations on liability under Delaware law and under the Pioneer Funds' declarations of trust are consistent with those applicable to directors of a corporation under Delaware law and will be beneficial in attracting and retaining in the future qualified persons to act as trustees. 70 Shareholder Voting Delaware law provides that a Delaware statutory trust's declaration of trust or by-laws may set forth provisions related to voting in any manner. This provision appears to permit trustee and shareholder voting through computer or electronic media. For an investment company with a significant number of institutional shareholders, all with access to computer or electronic networks, the use of such voting methods could significantly reduce the costs of shareholder voting. However, the advantage of such methods may not be realizable unless the SEC modifies its proxy rules. Also, as required by the 1940 Act, votes on certain matters by trustees would still need to be taken at actual in-person meetings. Board Composition Delaware law explicitly provides that separate boards of trustees may be authorized for each series of a Delaware statutory trust. Whether separate boards of trustees can be authorized for series of a Massachusetts business trust is unclear under Massachusetts law. As always, the establishment of any board of trustees of a registered investment company must comply with applicable securities laws, including the provision of the 1940 Act regarding the election of trustees by shareholders. Establishing separate boards of trustees would, among other things, enable the series of a Delaware statutory trust to be governed by individuals who are more familiar with such series' particular operations. ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS Investment Adviser Pioneer serves as the investment adviser to each Pioneer Fund. Pioneer oversees each fund's operations and is responsible for the day-to-day management of the fund's portfolio. In the case of Pioneer Focused Equity Fund, Pioneer supervises the fund's subadviser, who is responsible for the day-to-day management of the fund's portfolio. Pioneer is an indirect, wholly owned subsidiary of UniCredito Italiano S.p.A., one of the largest banking groups in Italy. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of March 31, 2006, assets under management were approximately $199.3 billion worldwide, including over $50.5 billion in assets under management by Pioneer. Pioneer's main office is at 60 State Street, Boston, Massachusetts 02109. Pioneer's U.S. mutual fund investment history includes creating one of the first mutual funds in 1928. The Board of Trustees of the Pioneer Funds is responsible for overseeing the performance of Pioneer Funds' investment adviser and determining whether to approve and renew a fund's investment management agreement. Distributor and Transfer Agent PFD is the fund's distributor. Pioneer Investment Management Shareholder Services, Inc. ("PIMSS") is the fund's transfer agent. The fund compensates PFD and the transfer agent for their services. PFD and the transfer agent are affiliates of Pioneer. Disclosure of Portfolio Holdings The fund's policies and procedures with respect to the disclosure of the fund's portfolio securities are described in the statement of additional information and on Pioneer's website at www.pioneerinvestments.com. Buying, Exchanging and Selling Shares of the Pioneer Funds Net Asset Value. Each fund's net asset value is the value of its portfolio of securities plus any other assets minus its operating expenses and any other liabilities. Each fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). Each fund generally values its portfolio securities using closing market prices or readily available market quotations. When closing market prices or market quotations are not available or are considered by Pioneer to be unreliable, the fund uses a security's fair value. All methods of determining the value of a security used by the fund, including those discussed below, on a basis other than market value, are forms of fair value. All valuations of securities on a fair value basis are made pursuant to procedures adopted by the Board of Trustees. The use of fair value pricing by the fund may cause the net asset value of its shares to differ from the net asset value that would be calculated only using market prices. For market prices and quotations, as well as for some fair value methods, the fund relies upon securities prices provided by pricing services. 71 Each fund uses the fair value of a security, including a non-U.S. security, when Pioneer determines that the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security at the time the fund calculates its net asset value. This may occur for a variety of reasons that affect either the relevant securities markets generally or the specific issuer. For example, with respect to non-U.S. securities held by the fund, developments relating to the securities market or the specific issuer may occur between the time the primary market closes and the time the fund determines its net asset value. In those circumstances, the fund may use the fair value of the security. International securities markets may be open on days when the U.S. markets are closed. For this reason, the values of any international securities owned by the fund could change on a day you cannot buy or sell shares of the fund. Certain types of securities, including those discussed in this paragraph, are priced using fair value rather than market prices. Each fund uses a pricing matrix to determine the value of fixed income securities that do not trade daily. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities and historical trading patterns in the market for fixed income securities. Each fund values cash equivalent securities with remaining maturities of 60 days or less at amortized cost. To the extent that a fund invests in the shares of other registered open-end investment companies that are not traded on an exchange (mutual funds), such shares are valued at their published net asset values per share as reported by the funds. The prospectuses of these funds explain the circumstances under which the funds will use fair value pricing and the effects of using fair value pricing. Distribution and Service Plans. Each fund has adopted a distribution plan for its Class A, Class B, Class C and Class R shares (if issued) in accordance with Rule 12b-1 under the 1940 Act. Under each plan, the fund pays distribution and service fees to PFD. Because these fees are an ongoing expense of the fund, over time they increase the cost of your investment and your shares may cost more than shares that are subject to other types of sales charges. Additional Payments to Financial Intermediaries. There are two principal ways you compensate the financial intermediary through which you buy shares of each fund--directly, by the payment of sales commissions, if any; and indirectly, as a result of the fund paying Rule 12b-1 fees. Pioneer and its affiliates may make additional payments to your financial intermediary. These payments by Pioneer may provide your financial intermediary with an incentive to favor the Pioneer Funds over other mutual funds or assist the distributor in its efforts to promote the sale of a fund's shares. Financial intermediaries include broker-dealers, banks (including bank trust departments), registered investment advisers, financial planners, retirement plan administrators and other types of intermediaries. Pioneer makes these additional payments (sometimes referred to as "revenue sharing") to financial intermediaries out of its own assets. Revenue sharing is not an expense of the Pioneer Funds. Pioneer may base these payments on a variety of criteria, including the amount of sales or assets attributable to the financial intermediary or as a per transaction fee. Not all financial intermediaries receive additional compensation and the amount of compensation paid varies for each financial intermediary. In certain cases, these payments could be significant. Pioneer determines which firms to support and the extent of the payments it is willing to make, generally choosing firms that have a strong capability to effectively distribute shares of the Pioneer Funds and that are willing to cooperate with Pioneer's promotional efforts. Pioneer also may compensate financial intermediaries for providing certain administrative services and transaction processing services. Pioneer may benefit from revenue sharing if the intermediary features the Pioneer Funds in its sales system (such as by placing certain Pioneer Funds on its preferred fund list or giving access on a preferential basis to members of the financial intermediary's sales force or management). In addition, the financial intermediary may agree to participate in the distributor's marketing efforts (such as by helping to facilitate or provide financial assistance for conferences, seminars or other programs at which Pioneer personnel may make presentations on the funds to the intermediary's sales force). To the extent intermediaries sell more shares of the Pioneer Funds or retain shares of the Pioneer Funds in their clients' accounts, Pioneer receives greater management and other fees due to the increase in the Pioneer Funds' assets. Although an intermediary may request additional compensation from Pioneer to offset costs incurred by the financial intermediary in servicing its clients, the intermediary may earn a profit on these payments, if the amount of the payment may exceed the intermediary's costs. The compensation that Pioneer pays to financial intermediaries is discussed in more detail in the fund's statement of additional information. Your intermediary may charge you additional fees or commissions other than those disclosed in this prospectus. Intermediaries may categorize and disclose these arrangements differently than the discussion above and in the statement of additional information. You can ask your financial intermediary about any payments it receives from Pioneer or the Pioneer Funds, as well as about fees and/or commissions it charges. Pioneer and its affiliates may have other relationships with your financial intermediary relating to the provision of services to the funds, such as providing omnibus account services or effecting portfolio transactions for the Pioneer Funds. If your intermediary provides these 72 services, Pioneer or the Pioneer Funds may compensate the intermediary for these services. In addition, your intermediary may have other relationships with Pioneer or its affiliates that are not related to the funds. Opening Your Account. If your shares are held in your investment firm's name, the options and services available to you may be different from those described herein or in a Pioneer Fund's prospectus. Ask your investment professional for more information. If you invest in a Pioneer Fund through investment professionals or other financial intermediaries, including wrap programs and fund supermarkets, additional conditions may apply to your investment in a Pioneer fund, and the investment professional or intermediary may charge you a transaction-based or other fee for its services. These conditions and fees are in addition to those imposed by the Pioneer Fund and its affiliates. You should ask your investment professional or financial intermediary about its services and any applicable fees. Account Options. Use your account application to select options and privileges for your account. You can change your selections at any time by sending a completed account options form to the transfer agent. You may be required to obtain a signature guarantee to make certain changes to an existing account. Call or write to the transfer agent for account applications, account options forms and other account information: PIONEER INVESTMENT MANAGEMENT SHAREHOLDER SERVICES, INC. P.O. Box 55014 Boston, Massachusetts 02205-5014 Telephone 1-800-225-6292 Telephone Transaction Privileges. If your account is registered in your name, you can buy, exchange or sell shares of the Pioneer funds by telephone. If you do not want your account to have telephone transaction privileges, you must indicate that choice on your account application or by writing to the transfer agent. When you request a telephone transaction the transfer agent will try to confirm that the request is genuine. The transfer agent records the call, requires the caller to provide validating information for the account and sends you a written confirmation. Each Pioneer Fund may implement other confirmation procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker-dealer or other third party. Online Transaction Privileges. If your account is registered in your name, you may be able to buy, exchange or sell fund shares online. Your investment firm may also be able to buy, exchange or sell your fund shares online. To establish online transaction privileges complete an account options form, write to the transfer agent or complete the online authorization screen on www.pioneerinvestments.com. To use online transactions, you must read and agree to the terms of an online transaction agreement available on the Pioneer website. When you or your investment firm requests an online transaction the transfer agent electronically records the transaction, requires an authorizing password and sends a written confirmation. Each Pioneer fund may implement other procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker-dealer or other third party. You may not be able to use the online transaction privilege for certain types of accounts, including most retirement accounts. Share Price. If you place an order to purchase, exchange, or sell shares with the transfer agent, your investment firm or plan administrator by the close of regular trading on the New York Stock Exchange (currently 4:00 p.m. Eastern time), your transaction will be completed at the share price determined as of the close of trading on the New York Stock Exchange on that day. If your order is placed with the transfer agent, your investment firm or plan administrator after 4:00 p.m., or your order is not in good order, your transaction will be completed at the share price next determined after your order is received in good order by the fund. Your investment firm or plan administrator is responsible for transmitting your order to the fund in a timely manner. Buying Pioneer Fund Shares. You may buy shares of a Pioneer fund from any investment firm that has a sales agreement with PFD. If you do not have an investment firm, please call 1-800-225-6292 for information on how to locate an investment professional in your area. Participants in retirement plans generally must contact the plan's administrator to purchase shares. You can buy shares of the Pioneer funds at the offering price. PFD may reject any order until it has confirmed the order in writing and received payment. The fund reserves the right to stop offering any class of shares. Minimum Investment Amounts. Your initial investment for Class A, Class B and Class C shares must be at least $1,000, and for Class Y shares must be at least $5,000,000. There is no minimum initial investment amount for Class R shares. Additional investments must be at least $100 for Class A shares and $500 for Class B and Class C shares. There is no minimum additional investment amount 73 for Class Y or Class R shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. The minimum investment amount does not apply for purposes of the Reorganization. Maximum Purchase Amounts. Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. These limits are applied on a per transaction basis. Class A shares, Class Y shares and Class R shares are not subject to a maximum purchase amount. Exchanging Pioneer Fund Shares. You may exchange your shares in a Pioneer Fund for shares of the same class of another Pioneer mutual fund. In connection with the Reorganization, Pioneer Government Income Fund's Class A shareholders will have the opportunity to exchange their shares for Class Y shares of Pioneer Government Income Fund at net asset value without any initial or contingent sales charge. Your exchange request must be for at least $1,000 unless the fund you are exchanging into has a different minimum. You may make up to four exchange redemptions of $25,000 or more per account per calendar year. In determining whether the exchange redemption limit has been reached, Pioneer may aggregate a series of exchanges (each valued at less than $25,000) and/or fund accounts that appear to be under common ownership or control. Pioneer may view accounts for which one person gives instructions or accounts that act on advice provided by a single source to be under common control. The exchange limitation does not apply to automatic exchange transactions or to exchanges made by participants in employer-sponsored retirement plans qualified under Section 401(a) of the Code. While financial intermediaries that maintain omnibus accounts that invest in the fund are requested to apply the exchange limitation policy to shareholders who hold shares through such accounts, we do not impose the exchange limitation policy at the level of the omnibus account and are not able to monitor compliance by the financial intermediary with this policy. Each Pioneer Fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred sales charge at the time of the exchange. An exchange generally is treated as a sale and a new purchase of shares for federal income tax purposes. Shares you acquire as part of an exchange and shares your acquire as a result of this Reorganization will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. Selling Pioneer Fund Shares. Your shares will be sold at net asset value per share next calculated after the Pioneer Fund or its authorized agent receives your request in good order. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. Each Pioneer Fund generally will send your sale proceeds by check, bank wire or electronic funds transfer. Normally you will be paid within seven days. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below. If you are selling shares from a retirement account other than an IRA, you must make your request in writing. You may have to pay federal income taxes on a sale or an exchange or any distributions received in cash or additional shares. Good order means that: o You have provided adequate instructions o There are no outstanding claims against your account o There are no transaction limitations on your account o If you have any Pioneer Fund share certificates, you submit them and they are signed by each record owner exactly as the shares are registered o Your request includes a signature guarantee if you: -- Are selling over $100,000 or exchanging over $500,000 worth of shares -- Changed your account registration or address within the last 30 days -- Instruct the transfer agent to mail the check to an address different from the one on your account -- Want the check paid to someone other than the account owner(s) -- Are transferring the sale proceeds to a Pioneer mutual fund account with a different registration 74 - -------------------------------------------------------------------------------------------------------------------------- Buying Shares Exchanging Shares - -------------------------------------------------------------------------------------------------------------------------- THROUGH YOUR Normally, your investment firm will send your Normally, your investment firm will send your INVESTMENT FIRM purchase request to the Pioneer Funds' transfer exchange request to the Pioneer Fund's agent. transfer agent.

You cannot obtain a signature guarantee from a notary public. The Pioneer Funds generally will accept only medallion signature guarantees. A medallion signature guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution that is participating in a medallion program recognized by the Securities Transfer Association. Signature guarantees from financial institutions that are not participating in one of these programs are not accepted as medallion signature guarantees. The Pioneer Funds may accept other forms of guarantee from financial intermediaries in limited circumstances. Fiduciaries and corporations are required to submit additional documents to sell Pioneer Fund shares. Exchange Limitation. You may make up to four exchange redemptions of $25,000 or more per account per calendar year out of the fund. Each fund's exchange limitation is intended to discourage short-term trading in fund shares. Short-term trading can increase the expenses incurred by the fund and make portfolio management less efficient. In determining whether the exchange redemption limit has been reached, Pioneer may aggregate a series of exchanges (each valued at less than $25,000) and/or fund accounts that appear to be under common ownership or control. Pioneer may view accounts for which one person gives instructions or accounts that act on advice provided by a single source to be under common control. The exchange limitation does not apply to automatic exchange transactions or to exchanges made by participants in employer-sponsored retirement plans qualified under Section 401(a) of the Code. While financial intermediaries that maintain omnibus accounts that invest in the fund are requested to apply the exchange limitation policy to shareholders who hold shares through such accounts, we do not impose the exchange limitation policy at the level of the omnibus account and are not able to monitor compliance by the financial intermediary with this policy. Distribution Options. Each Pioneer Fund offers three distribution options. Any fund shares you buy by reinvesting distributions will be priced at the applicable net asset value per share. (1) Unless you indicate another option on your account application, any dividends and capital gain distributions paid to you by the fund will automatically be invested in additional fund shares. (2) You may elect to have the amount of any dividends paid to you in cash and any capital gain distributions reinvested in additional shares. (3) You may elect to have the full amount of any dividends and/or capital gain distributions paid to you in cash. 77 Options (2) or (3) are not available to retirement plan accounts or accounts with a current value of less than $500. If your distribution check is returned to the transfer agent or you do not cash the check for six months or more, the transfer agent may reinvest the amount of the check in your account and automatically change the distribution on your account to option (1) until you request a different option in writing. These additional shares will be purchased at the then current net asset value. Directed Dividends. You can invest the dividends paid by one of your Pioneer mutual fund accounts in a second Pioneer mutual fund account. The value of your second account must be at least $1,000. You may direct the investment of any amount of dividends. There are no fees or charges for directed dividends. If you have a retirement plan account, you may only direct dividends to accounts with identical registrations. Excessive Trading. Frequent trading into and out of the fund can disrupt portfolio management strategies, harm fund performance by forcing the fund to hold excess cash or to liquidate certain portfolio securities prematurely and increase expenses for all investors, including long-term investors who do not generate these costs. An investor may use short-term trading as a strategy, for example, if the investor believes that the valuation of the fund's portfolio securities for purposes of calculating its net asset value does not fully reflect the then current fair market value of those holdings. The fund discourages, and does not take any intentional action to accommodate, excessive and short-term trading practices, such as market timing. Although there is no generally applied standard in the marketplace as to what level of trading activity is excessive, we may consider trading in the fund's shares to be excessive for a variety of reasons, such as if: o You sell shares within a short period of time after the shares were purchased; o You make two or more purchases and redemptions within a short period of time; o You enter into a series of transactions that is indicative of a timing pattern or strategy; or o We reasonably believe that you have engaged in such practices in connection with other mutual funds. The fund's Board of Trustees has adopted policies and procedures with respect to frequent purchases and redemptions of fund shares by fund investors. Pursuant to these policies and procedures, we monitor selected trades on a daily basis in an effort to detect excessive short-term trading. If we determine that an investor or a client of a broker has engaged in excessive short-term trading that we believe may be harmful to the fund, we will ask the investor or broker to cease such activity and we will refuse to process purchase orders (including purchases by exchange) of such investor, broker or accounts that we believe are under their control. In determining whether to take such actions, we seek to act in a manner that is consistent with the best interests of the fund's shareholders. While we use our reasonable efforts to detect excessive trading activity, there can be no assurance that our efforts will be successful or that market timers will not employ tactics designed to evade detection. If we are not successful, your return from an investment in the fund may be adversely affected. Frequently, fund shares are held through omnibus accounts maintained by financial intermediaries such as brokers and retirement plan administrators, where the holdings of multiple shareholders, such as all the clients of a particular broker, are aggregated. Our ability to monitor trading practices by investors purchasing shares through omnibus accounts is limited and dependent upon the cooperation of the financial intermediary in observing the fund's policies. In addition to monitoring trades, the policies and procedures provide that: o The fund imposes limitations on the number of exchanges out of an account holding the fund's Class A, Class B, Class C or Class R shares that may occur in any calendar year. o Certain funds managed by Pioneer have adopted redemption fees that are incurred if you redeem shares within a short period after purchase, including exchanges. These redemption fees are described in the applicable prospectuses under "Fees and expenses." The fund may reject a purchase or exchange order before its acceptance or an order prior to issuance of shares. The fund may also restrict additional purchases or exchanges in an account. Each of these steps may be taken, for any reason, without prior notice, including transactions that the fund believes are requested on behalf of market timers. The fund reserves the right to reject any purchase request by any investor or financial institution if the fund believes that any combination of trading activity in the account or related accounts is potentially disruptive to the fund. A prospective investor whose purchase or exchange order is rejected will not achieve the investment results, whether gain or loss, that would have been realized if the order were accepted and an investment made in the fund. The fund and its shareholders do not incur any gain or loss as a result of a rejected order. The fund may impose further restrictions on trading activities by market timers in the future. The fund's prospectus will be amended or supplemented to reflect any material additional restrictions on trading activities intended to prevent excessive trading. 78 Minimum Account Size. Each Pioneer Fund requires that you maintain a minimum account value of $500. If you hold less than $500 in your account, the fund reserves the right to notify you that it intends to sell your shares and close your account. You will be given 60 days from the date of the notice to make additional investments to avoid having your shares sold. This policy does not apply to certain qualified retirement plan accounts. Telephone and Website Access. You may have difficulty contacting the fund by telephone during times of market volatility or disruption in telephone service. On New York Stock Exchange holidays or on days when the exchange closes early, Pioneer will adjust the hours for the telephone center and for online transaction processing accordingly. If you are unable to reach the fund by telephone, you should communicate with the fund in writing. Share Certificates. The Pioneer Funds do not offer share certificates. Shares are electronically recorded. Any existing certificated shares can only be sold by returning your certificate to the transfer agent, along with a letter of instruction or a stock power (a separate written authority transferring ownership) and a signature guarantee. Other Policies. The fund and PFD reserve the right to: o reject any purchase or exchange order for any reason, without prior notice o charge a fee for exchanges or to modify, limit or suspend the exchange privilege at any time without notice. The fund will provide 60 days' notice of material amendments to or termination of the exchange privilege o revise, suspend, limit or terminate the account options or services available to shareowners at any time, except as required by the rules of the SEC The fund reserves the right to: o suspend transactions in shares when trading on the New York Stock Exchange is closed or restricted, when the SEC determines an emergency or other circumstances exist that make it impracticable for the fund to sell or value its portfolio securities o redeem in kind by delivering to you portfolio securities owned by the fund rather than cash. Securities you receive this way may increase or decrease in value while you hold them and you may incur brokerage and transaction charges and tax liability when you convert the securities to cash Dividends and Capital Gains. Pioneer America Income Trust generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income on the last business day of the month or shortly thereafter. Pioneer Government Income Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income on the last business day of the month or shortly thereafter. Pioneer Florida Tax Free Income Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income on the last business day of the month or shortly thereafter. Pioneer AMT-Free Municipal Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income on the last business day of the month or shortly thereafter. Pioneer Balanced Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income quarterly during March, June, September and December. Pioneer Classic Balanced Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income quarterly during March, June, September and December. Pioneer Focused Equity Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income in December. Pioneer Research Fund generally pays any distributions of net short- and long-term capital gains in November, and generally pays dividends from any net investment income in December. Each Pioneer Fund may also pay dividends and capital gain distributions at other times if necessary for the fund to avoid U.S. federal income or excise tax. If you invest in the fund close to the time that the fund makes a distribution, generally you will pay a higher price per share and you will pay taxes on the amount of the distribution whether you reinvest the distribution or receive it as cash. Taxes. For U.S. federal income tax purposes, distributions from each fund's net long-term capital gains (if any) are considered long-term capital gains and may be taxable to you at different maximum rates depending upon their source and other factors. Distributions from a fund's net short-term capital gains are taxable as ordinary income. Dividends, other than exempt-interest dividends, are taxable either as ordinary income or, if so designated by a fund and certain other conditions, including holding period requirements, are met by the fund and the shareholder, as "qualified dividend income" taxable to individual shareholders at a maximum 15% U.S. federal income tax rate. Generally, none of the dividends of Pioneer America Income Trust, Pioneer Government Income Fund, Pioneer Florida Tax Free Income Fund and Pioneer AMT-Free Municipal Fund meet the requirements to be treated as qualified dividend income. Dividends, other than exempt-interest dividends, and distributions are taxable, whether you take payment in cash or reinvest them to buy additional fund shares. 79 When you sell or exchange fund shares you will generally recognize a capital gain or capital loss in an amount equal to the difference between the net amount of sale proceeds (or, in the case of an exchange, the fair market value of the shares) that you receive and your tax basis for the shares that you sell or exchange. In January of each year the fund will mail to you information about your dividends, distributions and any shares you sold in the previous calendar year. You must provide your social security number or other taxpayer identification number to the fund along with the certifications required by the Internal Revenue Service when you open an account. If you do not or if it is otherwise legally required to do so, the fund will withhold 28% "backup withholding" tax from your dividends and distributions, sale proceeds and any other payments to you. You should ask your tax adviser about any federal, state, local and foreign tax considerations, including possible additional withholding taxes for non-U.S. shareholders. You may also consult the fund's statement of additional information for a more detailed discussion of qualified dividend income and other U.S. federal income tax considerations that may affect the fund and its shareowners. 80 FINANCIAL HIGHLIGHTS The following tables show the financial performance of each successor Pioneer Fund for the past five fiscal years and, if applicable, for any recent semiannual period.

Pioneer and its affiliates, together with a third party solicitation firm, have agreed to provide proxy solicitation services to your fund at a cost of approximately $267,000. Pioneer has agreed to pay 50% of the costs of preparing and printing the Proxy Statement/Prospectus and the solicitation costs incurred in connection with the Reorganizations. With respect to each Reorganization, the Pioneer Funds will each pay an equal portion of the remaining 50% of the costs incurred in connection with the such Reorganization. Revoking Proxies Each shareholder of your fund signing and returning a proxy has the power to revoke it at any time before it is exercised: o By filing a written notice of revocation with your fund's transfer agent, Pioneer Investment Management Shareholder Services, Inc., 60 State Street, Boston, Massachusetts 02109, or o By returning a duly executed proxy with a later date before the time of the meeting, or o If a shareholder has executed a proxy but is present at the meeting and wishes to vote in person, by notifying the secretary of your fund (without complying with any formalities) at any time before it is voted. Being present at the meeting alone does not revoke a previously executed and returned proxy. Outstanding Shares Only shareholders of record on July 31, 2006 (the "record date") are entitled to notice of and to vote at the meeting. As of the record date, the following shares of each fund requesting a vote of its shareholders were outstanding: Pioneer Fund Shares Outstanding (as of July 31, 2006) - ------------ ---------------------------------------- Pioneer America Income Trust Class A ........................... 9,681,057.708 Class B ........................... 2,685,953.397 Class C ........................... 2,183,748.528 Class R ........................... 91,356.613 Investor Class 3,518,176.794 Pioneer Balanced Fund Class A ........................... 8,711,311.121 Class B ........................... 1,359,896.513 Class C ........................... 987,339.848 Investor Class .................... 789,677.190 Pioneer Florida Tax Free Income Fund Class A ........................... 136,065.342 Class B ........................... 169,880.059 Class C ........................... 954.201 Class Y ........................... 3,379,931.145 Pioneer Focused Equity Fund Class A ........................... 1,004,657.472 Class B ........................... 808,706.282 Class C ........................... 2,807.506 Class Y ........................... 3,686,014.029 97 Other Business Your fund's Board of Trustees knows of no business to be presented for consideration at the meeting other than Proposals 1(a) -- 1(d). If other business is properly brought before the meeting, proxies will be voted according to the best judgment of the persons named as proxies. Adjournments If, by the time scheduled for the meeting, a quorum of shareholders of fund is not present or if a quorum is present but sufficient votes "for" the proposal have not been received, the persons named as proxies may propose an adjournment of the meeting to another date and time, and the meeting may be held as adjourned within a reasonable time after the date set for the original meeting without further notice. Any such adjournment will require the affirmative vote of a majority of the votes cast in person or by proxy at the session of the meeting to be adjourned. The persons named as proxies will vote all proxies in favor of the adjournment that voted in favor of the proposal or that abstained. They will vote against such adjournment those proxies required to be voted against the proposal. Broker non-votes will be disregarded in the vote for adjournment. If the adjournment requires setting a new record date or the adjournment is for more than 120 days of the original meeting (in which case the Board of Trustees of your fund will set a new record date), your fund will give notice of the adjourned meeting to its shareholders. Telephone and Internet Voting In addition to soliciting proxies by mail, by fax or in person, your fund may also arrange to have votes recorded by telephone, the Internet or other electronic means. The voting procedures used in connection with such voting methods are designed to authenticate shareholders' identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions and to confirm that their instructions have been properly recorded. If these procedures were subject to a successful legal challenge, such votes would not be counted at the shareholder meeting. The funds are unaware of any such challenge at this time. In the case of telephone voting, shareholders would be called at the phone number PIMSS has in its records for their accounts and would be asked for their Social Security number or other identifying information. The shareholders would then be given an opportunity to authorize proxies to vote their shares at the meeting in accordance with their instructions. In the case of automated telephone and Internet voting, shareholders would be required to provide their identifying information and will receive a confirmation of their instructions. Shareholders' Proposals Your fund is not required, and does not intend, to hold meetings of shareholders each year. Instead, meetings will be held only when and if required. Any shareholders desiring to present a proposal for consideration at the next meeting for shareholders must submit the proposal in writing, so that it is received by your fund at 60 State Street, Boston, Massachusetts 02109 within a reasonable time before the meeting. OWNERSHIP OF SHARES OF THE PIONEER FUNDS As of July 31, 2006, the Trustees and officers of each fund owned in the aggregate less than 1% of the outstanding shares of their respective funds. To the knowledge of each fund, as of July 31, 2006, the following persons owned of record or beneficially 5% or more of the outstanding shares of a class of each fund, respectively. - ---------------------------------------------------------------------------------------------- Number of Record Holder Share Class Shares Percent of Class - ---------------------------------------------------------------------------------------------- Pioneer Government Income Fund BISYS Retirement Services Class A 113,474.813 8.42% FBO Aeropres Corporation Retirement 700 17th Street, Suite 300 Denver, Co 80202-3531 - ---------------------------------------------------------------------------------------------- Pershing LLC 107,296.831 7.96% P.O.

Such transactions shall take place at the Closing (as defined in Paragraph 3.1 below). 1.2 (a) The Acquired Assets shall consist of all of the Acquired Fund's property, including, without limitation, all portfolio securities and instruments, dividends and interest receivables, cash, goodwill, contractual rights and choses in action of the Acquired Fund or the Acquired Fund in respect of the Acquired Fund, all other intangible property owned by the Acquired Fund, originals or copies of all books and records of the Acquired Fund, and all other assets of the Acquired Fund on the Closing Date.

B-4 PORTFOLIO MANAGEMENT DISCUSSION PIONEER GOVERNMENT INCOME FUND 1/31/06 Continued economic growth and rising short-term interest rates during the last six months created the backdrop for the positive return earned by shareholders in Pioneer Government Income Fund. In the following interview, Richard Schlanger, the Fund's Portfolio Manager and a member of the Pioneer fixed-income team, discusses the factors that affected the fixed-income market and the Fund over the past half year. Q. How did the Fund perform during the period? A: For the six-month period ended January 31, 2006, Class A shares of Pioneer Government Income Fund produced a total return of 0.67% at net asset value. The Fund underperformed its benchmark, the Lehman Brothers Government Bond Index, which returned 0.77% for the same period. It also fell short of the 1.28% return of the Lehman Brothers Fixed Rate Mortgage-Backed Securities Index and the average 0.86% return generated by the funds in the U.S. Mortgage Funds Category of Lipper, an independent monitor of mutual fund performance. At the end of the period, the 30-day SEC yield for Class A shares was 3.58%. The Fund held 106 issues with an average quality of AAA.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q. What was the investment environment like during the period? A: In an environment of relatively strong economic growth, the Federal Reserve raised the federal funds rate five times from 3.25% to 4.50% during the period. The Fed's actions resulted in a flattening of the yield curve, with short-term yields and longer-term yields at approximately the same level. For a short period, the yield curve inverted slightly, with longer-term yields falling below short-term yields. While long-term yields on U.S. Treasury bonds were relatively low, they were among the highest among the developed countries, making them attractive to overseas investors. As a result, U.S. Government bonds benefited from an influx of money from foreign, as well as domestic, investors. The performance of government bonds was also enhanced by investors seeking quality. At a time when long-term yields declined and the bonds of corporate issuers, like General Motors and Ford, were downgraded by credit rating agencies, domestic investors saw little advantage to take on greater risk. As a result, they moved to purchasing government securities with relative safety. Q. What strategies did you use in managing the Fund? A: We continued to seek a high level of income without unduly risking capital. In making our investment decisions, we considered a variety of factors that influence economic activity and interest rates. These included the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of the U.S. dollar against world currencies. To take advantage of the flattening yield curve, we extended the portfolio's duration. At the beginning of the period, the portfolio had a relatively small Treasury bond position and a large allocation to mortgage-backed securities. Among mortgages, securities issued by the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) accounted for a far greater percentage of assets than those issued by the Government National Mortgage Association (Ginnie Mae). Because we believed mortgages had become too high priced and subject to prepayment, we lowered the Fund's mortgage holdings, while increasing the percentage of Treasury bonds. We established a position in Treasury Inflation Protected Securities (TIPS) on the belief that inflation might pick up. TIPS are securities whose principal is tied to the consumer price index, which is a monthly indicator that measures the price inflation of a representative basket of goods and services. When inflation accelerates, the principal on TIPS increases in value. The interest-rate payment on TIPS is calculated on the inflated principal. Q. What contributed to performance? A: The TIPS in the portfolio were the biggest contributor to performance. The portfolio's longer duration also contributed to results. Conventional mortgages issued by the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) underperformed those issued by the Government National Mortgage Association (Ginnie Mae). Both Fannie Mae and Freddie Mac are well represented in the top 25 holdings that constitute over 60% of the portfolio; Fannie Mae with B-5 33.5% of that total and Freddie Mac with 26.7%. They also have been in the headlines for more than a year because of accounting irregularities and concerns that these agencies were undercapitalized. Both agencies sold portions of their mortgage investment portfolios in order to raise funds to meet the higher capitalization levels required by the Office of Federal Housing Enterprise Oversight (OFHEO). The OFHEO has stated that both agencies are now adequately capitalized. Q. What is your financial outlook? A: We are generally positive in our outlook. We think the yield curve will temporarily invert, with short-term yields rising above long-term yields. However, we believe that the Fed may be near the end of its rate-raising cycle. We expect to see some heightened market volatility in the short term, as investors become familiar with the policies and philosophy of Benjamin Bernanke, the new Federal Reserve chairman. With the re-issuance of the 30-year Treasury bond, there is likely to be a greater supply of Treasury bonds in the next several months; however, this increase in supply is unlikely to affect bond prices significantly, as foreign and domestic demand for U.S. Treasury bonds continues to be strong. As in the past, we will carefully monitor the factors that influence the economy, inflation and monetary policy, and make adjustments to the portfolio that we believe have potential to increase income and preserve principal. When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. Investing in the securities of U.S. issuers with substantial foreign activities involves many of the same risks as investing in the securities of foreign issuers. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed income securities. Mortgage-Backed securities are also subject to pre-payments.

These opinions should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

B-11 PORTFOLIO MANAGEMENT DISCUSSION Pioneer America Income Trust 12/31/05 In a year marked by hurricanes, high energy prices, concerns about accelerating inflation and rising short-term interest rates, shareholders in Pioneer America Income Trust earned a positive return on their investment. In the interview below, Richard Schlanger, the Trust's day-to-day Portfolio Manager, discusses the factors that affected the fixed income market and the Trust over the past 12 months. Q. How did the Trust perform during the period? A: For the 12-month period ended December 31, 2005, Class A shares of Pioneer America Income Trust produced a total return of 1.84% at net asset value. The Trust underperformed its benchmark, the Lehman Brothers Government Bond Index, which returned 2.65% for the same period. It also underperformed the average 2.05% return generated by the General U.S. Government Funds Category of Lipper, Inc., an independent monitor of mutual fund performance. At the end of the period, the 30-day SEC yield for Class A shares was 3.17%. The Trust had 260 issues and the average quality of the portfolio was AAA. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, maybe worth more or less than their original cost. Q. What was the investment environment like during the period? A: Economic growth was relatively strong, and productivity remained high. In this environment, the Federal Reserve continued to reverse its accommodative monetary policy and raised interest rates eight times during the year, each time by a quarter point. At the end of 2005, the federal funds target rate was 4.25%, up from 2.25% in January 2005. (The federal funds rate is the rate banks charge for overnight loans. Since June 2004, the Fed has hiked interest rates 13 times, taking the federal funds rate from a 40-year low of 1% to the current 4.25%.) The net effect of the Fed's actions was a flattening of the yield curve, where short-term yields and longer-term yields were approximately the same. On December 30, 2005, the yield curve inverted slightly, with longer-term yields falling below short-term yields. (The yield curve shows the relationship between bond yields and maturity lengths.) During the year, government bonds benefited from an influx of money from both foreign and domestic investors. While long-term yields on U.S. Treasuries were relatively low, they were among the highest of the developed countries and attractive to overseas investors. The performance of government bonds was also enhanced by a flight to quality. At a time when long-term yields declined and the debt of General Motors and Ford was downgraded by credit rating agencies, domestic investors saw little advantage to taking on risk. As a result, they moved into the relative safety of government securities. Q. What strategies did you use in managing the Trust? A: As interest rates rose, we extended duration, or sensitivity to interest-rate changes, by reducing exposure to mortgage securities and adding to positions in Treasury issues and Treasury Inflation Protected Securities (TIPS). TIPS are securities whose principal is tied to the consumer price index, a monthly indicator that measures the price inflation of a representative basket of goods and services. When inflation accelerates, the principal on TIPS increases in value. The interest-rate payment on TIPS is calculated on the inflated principal. While inflation was not a problem in 2005, we are concerned about the potential for it to pick up. Oil prices are over $60 a barrel, the price of gold is at a 25-year high and the unemployment rate fell below 5%. These factors and others could lead to an upturn in inflation. At the end of the period, 59% of the portfolio was in mortgage pass-through securities issued by the Government National Mortgage Association, 40% was in Treasury issues and TIPS, and 1% was in cash. Q. What detracted from performance? A: Our positioning on the yield curve held back return. Throughout the 12 months, we maintained a bulleted strategy, which means we invested in bonds across the maturity spectrum, with the biggest concentration in the intermediate-term range of two-years to ten-years. While our short-term and long-term bonds did well, intermediate-term bonds detracted from performance. In hindsight, it would have been more advantageous to have had a barbelled configuration, overweighting the short and long ends of the yield curve and holding relatively few intermediate-term bonds. B-12 Q. What contributed to performance? A: During the second half of 2005, yields on 10-year Treasuries traded in a relatively narrow range of roughly 3.90% to a high of roughly 4.68%. As 10-year Treasuries declined in price and rose in yield, we extended duration. This aided results because 10-year Treasuries closed the year at 4.40%, down from their highs. A longer duration usually benefits a portfolio when yields decline. The performance of TIPS also helped boost the Trust's return. Q. What is your outlook? A: In general we are positive when looking ahead. While we believe the inverted yield curve may be indicating some moderating in economic growth, we do not think it is signaling recession. When the Fed began raising interest rates, the federal funds rate was extremely low at 1%. We think that the current 4.25% level is not restrictive, especially with an inflation rate of roughly 2.0% to 2.5%. While we think the consumer may cut back on spending, it is likely that business will pick up the slack. An increase in capital spending on the part of corporations may be enough to keep the economy growing at a respectable rate. The Fed may be in the late stages of its rate-raising cycle. Should the Fed ease rates somewhat, we believe intermediate-term securities will outperform longer-term securities. We are well-positioned should this occur. As we move into 2006, we believe the Trust should continue to provide income diversification for investors who want to avoid the risk associated with the more volatile areas of the fixed-income market and with equities. When interest rates rise, the prices of fixed income securities in the fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the fund will generally rise. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-Backed securities are also subject to pre-payments. Government guarantees apply to the underlying securities only and not to the prices and yields of the portfolio. At times, the fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

B-17 PORTFOLIO MANAGEMENT DISCUSSION Pioneer Classic Balanced Fund 1/31/06 With a sustained economic recovery and steady corporate profit growth as a backdrop, domestic equities performed relatively well during the six months ended January 31, 2006. However, returns generally were more modest in the fixed-income markets as the Federal Reserve Board continued to raise short-term rates and the yield differences between long- and short-term securities narrowed. The yield advantages of corporate bonds over government securities also grew tighter, making investments in corporate bonds less attractive to investors. In the following interview, Walter Hunnewell, Jr., who is one of Pioneer Classic Balanced Fund's co-managers, and Richard Schlanger, who is a member of Pioneer's Fixed Income team, discuss the markets and the factors that affected performance during the six months. Q. How did the Fund perform during the six months ended January 31, 2006? A: Pioneer Classic Balanced Fund (Class A shares) returned 4.37% during the six-month period, at net asset value. During the same period, the average return of the 698 funds in Lipper's balanced Fund category was 4.47%. In comparison, the Standard and Poor's 500 Index and the Lehman Brothers Government/Credit Bond Index returned 4.67% and 0.58%, respectively, over the same period.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q. What strategies do you use in managing the Fund? A: Almost two months into the period, on September 23, 2005, the former AmSouth Balanced Fund was reorganized as the Pioneer Classic Balanced Fund, and Pioneer Investment Management assumed portfolio management responsibilities. Since then, the Fund has been managed in accord with our equity and fixed-income disciplines, emphasizing fundamental research and drawing on the global resources of the Pioneer organization. As a balanced fund, the Fund is managed with the goal of seeking both capital growth and current income through a diversified portfolio of both equity and fixed-income securities. The Fund has a normal allocation of 60% equities and 40% fixed income, but the allocation can vary depending upon Pioneer's assessment of relative opportunities in the markets. Since Pioneer assumed management responsibilities, the equity portfolio has increased from about 60% of Fund assets to about 65% of assets. That was the result of both a deliberate policy to increase the Fund's emphasis on stocks and the appreciation of the value of equity assets in the portfolio. Q: What were the principal factors that affected the performance of the Fund's bond portfolio for the period? A: We believed that corporate bonds were becoming less attractive relative to mortgages and governments as their yield advantages narrowed. As a consequence, we reduced our corporate positions. We also de-emphasized bonds in the finance sector, whose earnings we believed were vulnerable as the Federal Reserve continued to raise short-term interest rates. We sold, for example, bonds issued by Prudential Funding and by Devon Financing. In addition, we sold DaimlerChrysler holdings because of our concerns surrounding the auto sector. At the same time, we added to our mortgage holdings and invested in long-term Treasuries because of the attractive income that they offered relative to other types of fixed-income securities. While we maintained a high quality portfolio, we looked for selective opportunities in corporate bonds where we had confidence in the underlying credit fundamentals of the companies behind them. The average credit quality of the portfolio's holdings was AA on January 31, 2006. About one-third of the portfolio's assets was invested in Treasuries and another one-third was invested in mortgages. Government agencies accounted for about 10% of fixed income assets, while corporate industrial bonds accounted for 21%. Bank and finance bonds were reduced to about 12% of fixed income assets. We kept average maturity and duration - both of which measure sensitivity to changes in interest rates - consistent with that of the benchmark Lehman Brothers Government/Credit Bond Index. The increasing emphasis on mortgage-backed securities helped performance, as did the lack of exposure to some of the more notable poor-performing corporate bonds, including securities issued by General Motors and Ford, the credit ratings of which have fallen from investment-grade to below investment-grade. B-18 Q: What were the principal factors that affected the performance of the Fund's equity portfolio during the six months? A: We shifted the portfolio's focus from a growth-oriented style to more of a value-oriented style, with an emphasis on reasonably priced large- and mid-cap stocks. We also looked to increase the dividend income from our stock holdings. Reflecting this shift, by January 31, 2006, the average price - as reflected by price/earnings ratios - of our holdings was lower than that of the benchmark Standard & Poor's 500 Index, but the average dividend yield was higher than the S&P 500's. In repositioning the equity portfolio, we sold our positions in many higher-priced growth stocks, including those of technology companies Cisco Systems and Qualcomm, biotechnology leader Amgen, and eBay, the Internet auctioneer. We established large positions in less expensively priced, higher-yielding companies, including Bristol-Myers and Merck, two pharmaceutical companies that our research indicated offered potential interesting opportunities after being out of favor in the market. Another new holding was Washington Mutual, which was trading at a low price and offered a relatively high yield. In addition, we invested in some companies, such as Federated Department Stores, not because we were attracted by their dividend yield, but because we believed they offered superior capital appreciation potential as the result of their unrecognized earnings power. We also established a relatively small position in several real estate investment trusts (REITs), which had been absent from the portfolio. However, we limited the Fund's exposure because of our concern about the vulnerability of REITs to increases in interest rates. One of our larger REIT positions was Brandywine Realty. Q: What were some of the individual equity investments that particularly influenced results? A: We overweighted the energy sector, which helped performance substantially as energy stocks rallied and the prices of commodities increased. Among the better performers were oil services companies such as Global Santa Fe and Schlumberger, as well as Marathon Oil, an integrated oil company. Deere, the farm equipment company, was our largest individual holding by the end of the six months and made a substantial contribution to performance. We increased our weighting in Deere because it was selling at what we thought was a very low price. In our opinion the dividend yield was not high, but we believed it offered superior price appreciation potential because we think the overall stock market is underestimating how long demand for farm equipment will be sustained. Merck, which we added to the portfolio, also performed well as its stock value recovered from a depressed level. One of the disappointing performers was Dow Chemical, whose stock price fell because investors had questions about pricing for ethylene products, a significant part of Dow's business. However, we believed that ethylene inventories are generally low and Dow should have an opportunity to sustain good pricing for its products. As a result, we continue to favor the company. Q. What is your investment outlook? A: We think that the economy will continue to expand and corporate profits should continue to improve, but the rates of economic growth and corporate earnings growth may begin to slow during the current year. As we enter 2006, we believe the stock market is reasonably valued. We also think the emphasis on higher dividend-paying stocks gives the Fund the potential to do well in the current environment. We have found interesting opportunities among higher-dividend pharmaceutical companies and telecommunication services companies and in companies that have demonstrated abilities to produce cash flow to support and increase their dividend payouts to shareholders. We believe the Federal Reserve is likely to continue to raise short-term interest rates, at least in the near term. In managing the fixed-income portfolio, we will look for signals about any shifts in policy emphasis under new Federal Reserve Chairman Ben Bernanke, although we think the Fed will remain determined to keep inflationary pressures under control. If longer-term interest rates were to increase significantly, bonds could provide an interesting opportunity for investment. Overall, we believe demand for U.S. securities by foreign investors should help provide continued support for bond prices in the United States. When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. The portfolio invests in REIT securities, the value of which can fall for a variety of reasons, such as declines in rental income, fluctuating interest rates, poor property management, environmental liabilities, uninsured damage, increased competition, or changes in real estate tax laws. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and B-19 political conditions. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-Backed securities are also subject to pre-payments. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory development or other risks affecting those industries and sectors.

B-24 Portfolio Management Discussion Pioneer Balanced Fund 12/31/05 The nation's economy grew persistently throughout 2005, producing strong earnings growth and healthier corporate balance sheets. The economy proved resilient to the effects of a variety of challenges, from hurricane damage in the Gulf Coast to sharply rising energy and commodity prices. To head off the possibility that inflationary pressures would build up as the economy grew, the U.S. Federal Reserve continued to tighten monetary policy. The Fed raised the Fed Funds rate eight different times during the calendar year. In the following interview, Timothy Mulrenan, who is responsible for the equity portfolio of Pioneer Balanced Fund, and Richard Schlanger, who is responsible for the Fund's fixed-income portfolio, discuss the markets and the factors that affected performance. Q. How did the Fund perform? A: Class A shares of Pioneer Balanced Fund returned 3.25% at net asset value during the 12 months ended December 31, 2005. In comparison, the Standard & Poor's 500 Index and the Lehman Brothers Aggregate Bond Index returned 4.91% and 2.43%, respectively, over the same period. Additionally, the average return of the 650 funds in Lipper's Balanced Fund category was 4.69%.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q. What were the principal factors that affected Fund performance? A: Throughout the 12 months, we overweighted equities, with a target allocation of about 64% of Fund assets versus a 60% normal allocation. We invested the remaining 36% of assets in fixed income securities. We placed this emphasis on stocks because of the favorable earnings environment and our view that stocks were likely to produce positive returns during the year. At the same time, we were not sure how far the Federal Reserve Board intended to push short-term interest rates, and we believed bonds, in general, were fully valued in the market. The equity market had a positive year, buoyed by positive earnings - profits of S&P 500 companies grew approximately 13%. Despite rising short-term interest rates and higher commodity prices, long-term interest rates were essentially unchanged over the 12 months. Other factors giving support to stock valuations included many stock buyback programs, initiated by corporations with more cash on their balance sheets, and increasing merger and acquisition activity. Despite all these positive factors, stock performance was held back by a number of concerns, including fears that higher short-term interest rates and high energy costs might undermine future corporate profitability. The major development in the fixed-income market was the dramatic flattening of the yield curve - which reflects the difference in yields between short-term and long-term securities. Normally, the yield curve steepens - yield differences become greater - the greater the difference in maturity between short- and long-term securities. However, the yield curve became so flat that it actually partially inverted by the end of the year, a highly unusual phenomenon in which 10-year yields actually became slightly lower than two-year yields. Despite the efforts of the Federal Reserve to raise short-term rates, long-term rates tended to fall or remain stable because of strong demand for U.S. Treasuries by international bond investors. Q. What areas in the equity and fixed income market performed better than others? A: In the equity market, mid-cap stocks did better than either small or large-cap stocks, continuing a multi-year run for medium-sized companies. The value style of investing slightly outperformed the growth style, but the growth style performed somewhat better in the final two months of the year. We manage the Fund in a large cap growth style. Driven by the dramatic increases in oil and natural gas prices, energy stocks were by far the performance leaders in the equity market. On average, energy stocks rose by 30%. Utilities also performed relatively well, while consumer discretionary stocks - especially in the automotive and media industries - lagged. In the fixed-income market, long-term investments outperformed short- and intermediate-term investments. With a backdrop of rising profits, investment grade and high-yield corporate bonds tended to do well. The notable exception was among a few fallen angels whose financial problems led to credit rating downgrades. Two highly visible examples were General Motors and Ford, both of which were downgraded from investment grade to high yield. Among governments, Treasuries outperformed mortgages, with long-term Treasuries performing especially well. B-25 Q. What equity investments had the greatest influence on performance? A: Our overweight position in energy stocks for most of the year and our stock selection within the energy sector helped boost performance. Two standout selections were National Oilwell Varco, a leading provider of oil field equipment, and ENSCO International, a prominent offshore contract driller. National Oilwell Varco's stock price rose substantially, driven by robust earnings, favorable pricing and a growing backlog of orders. We trimmed the position and took profits during the year. ENSCO's stock price appreciated by about 40% as the day rates for its oil rigs surged against a backdrop of growing demand and a tight supply of the drilling platforms. By the end of the year, we had taken some profits, but still held ENSCO, and moved to a slight underweight position in energy. Our investments in health care also did well. Shares of generic pharmaceutical manufacturer IVAX doubled. The company was helped by both an impressive pipeline of new drugs approaching market and an acquisition offer from a competitor. Amgen, a major biotechnology firm, benefited from strong revenue gains across all its product lines and its own promising pipeline of new products under development, including prospective drugs for treatment of cancer and arthritis. Among the more disappointing positions was our investment in Symantec, a leading software security firm. Its stock price declined in the second half of the year after the company announced earnings that failed to meet expectations. Investors also became concerned about price competition in the software security industry and the possibility of new competition from Microsoft. The U.K.- based telecommunications services giant Vodafone also declined as its profit margins came under pressure because of difficulties in operations in Japan and in Europe. Also detracting from results was our investment in Family Dollar, a low-price retailer. Lower income consumers, who make up a substantial part of Family Dollar's customer base, were particularly hard hit by rising energy prices. We eliminated our positions in Symantec and in Family Dollar. Q. What fixed-income investments had the greatest influence on performance? A: Our positioning on the yield curve did not help. In a period in which short-term interest rates were rising and longer-term rates were relatively stable, the best positioning would have been a bar-belled approach. That would place greater emphasis both on short-term securities - to take advantage of rising yields - and on long-term securities to take advantage of their high yields and price stability. However, we pursued a bulleted-approach with investments throughout the yield curve - including intermediate-term securities, which tended to under perform other parts of the market. Also holding back results was our investment in bonds of auto parts manufacturer Delphi, which filed for bankruptcy protection during the year. We had liquidated our position in Delphi prior to the bankruptcy filing. During the year, as yields in many part of the market rose, we extended duration - a measure of sensitivity to interest rate changes. Duration on December 31, 2005, was 4.55 years, compared to 3.98 years six months earlier. Average credit quality remained at AA-, although we did reduce our exposure to high yield securities. We also cut our mortgage position, while raising our allocation to Treasuries and agencies. Mortgages, however, still represented the largest sector weighting, at 44.7% of fixed income assets at year's end. Treasuries and agencies represented 24% of assets, and industrials and utilities were 20%. Q. What is your investment outlook? A: We expect positive performance in the equity market if an environment of rising profits and strengthening balance sheets continues. We believe two key factors should influence the equity markets in 2006: the continued revival of corporate capital spending, which already grew by 20% during 2005 and the emergence of a performance edge by growth stocks, which have underperformed value stocks for several years. As we enter a new year, value stocks have reached price levels on a par with growth stocks, and we believe growth stocks should begin to outperform because of their greater earnings growth potential. Given this view, we have added to our positions in companies that can benefit from increasing capital spending, with investments in industrials, telecommunications equipment and information technology companies. We have also reduced our exposure to consumer discretionary stocks, although we continue to emphasize consumer staples with their more consistent earnings. For the fixed-income market, we anticipate that the Federal Reserve will move cautiously because of concerns about high debt levels of consumers. We believe the Fed may raise short-term rates two or three times more. We think the Fed Funds rate may level off in the range of 4.75% to 5.00%. Historically, the Fed has begun lowering rates four to six months after the end of its rate-hike cycles, and we believe this may occur again late in 2006. If that occurs, we expect the short-end and the intermediate parts of the yield curve to outperform the long-end, and we would position the portfolio accordingly. Because of the tightening labor supply and high energy costs, we are carefully watching inflation trends and are prepared to become more defensive. We already have established a position in Treasury Inflation Protective Securities (TIPS) to guard against the impact of higher inflation. When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial B-26 failure of underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. The portfolio invests in REIT securities, the value of which can fall for a variety of reasons, such as declines in rental income, fluctuating interest rates, poor property management, environmental liabilities, uninsured damage, increased competition, or changes in real estate tax laws. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-Backed securities are also subject to pre-payments. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

B-31 PORTFOLIO MANAGEMENT DISCUSSION Pioneer AMT-Free Municipal Fund 12/31/05 In the following interview, Portfolio Manager Stephen C. Bauer outlines the investment environment for tax-free bonds during the Fund's most recent fiscal year, Fund performance, his investment philosophy and strategy, and his outlook. Q. How did the Fund perform during its most recent fiscal year? A: For the 12-month period ended December 31, 2005, Pioneer AMT-Free Municipal Fund's Class A shares produced a 4.81% return; Class B shares returned 4.02%; and Class C shares 3.78%, each at net asset value. The Fund's benchmark, the Lehman Brothers Municipal Bond Index, returned 3.51% and the average return of the Lipper General Municipal Debt Funds category was 3.00%. Lipper is an independent monitor of mutual fund performance. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: Will you describe the investing environment for tax-exempt bonds during the time period? A: For the second year in a row, the environment for long-term municipals was remarkably stable. The U.S. economy maintained steady Gross Domestic Product growth throughout the year, energy prices soared, but inflation was muted. Yields of long-term municipals and Treasury securities continue to be low, close to their all-time low in June 2003. (The Bond Buyer 40 Municipal Index, an industry standard for measuring long-term municipal bond interest rates, closed the period at 4.77%.) The trading range for long-term municipals was extremely narrow for the period. This was mildly surprising given that the Federal Reserve continued to raise short term interest rates aggressively throughout 2005, and that most economists had once again predicted that long-term rates would increase. Intermediate-term rates rose, but long-term rates, where this portfolio is concentrated, were slightly lower during the past 12 months. This meant that long-term municipal investors generally earned their coupon interest rate, plus some price appreciation (as bond yields decline, bond prices rise, and vice versa). Q. How would you characterize supply and demand for municipal bonds? A: The year 2005 set a record for total volume of new municipal issues during the year, over $400 billion. The volume was much higher than anticipated and largely related to tax-free bond refundings, where issuers take advantage of declining interest rates and refinance higher yielding bonds at lower rates. Though demand from individual investors remained flat during the period, tremendous demand for municipal bonds came from property and casualty insurance companies. These firms have actually experienced strong profit growth during a terrible year for natural disasters in 2005, as they have been able to raise their rates and benefit from increased demand from businesses and consumers for property and casualty insurance. Q. Will you restate your philosophy in managing the Fund? A: My investment philosophy is to stay fully invested in long-term bonds. Pioneer AMT-Free Municipal Fund is a long-term fund, and I feel responsible to maintain it as such, and not to try to predict the direction or magnitude of interest rate changes and make maturity or other investment decisions on that basis. At the close of the period, the Fund's average maturity was approximately 21 years. In addition, I believe that being invested in long-term municipal bonds is a sound strategy for two reasons: First, long-term municipal bonds consistently yield and more than shorter-term bonds. There have been no inverse yield curves in the municipal bond market (i.e., where long-term rates are lower than short-term rates). Of course, the reason that longer-term municipal bonds yield more is that they are more volatile than bonds of shorter maturity. Greater interest rate risk is the trade-off for more total return through the accumulation of higher yield over the long term. The second reason is that I take a very long-term view of the bond market. I rarely make any transactions that I think will pay off only over the short term. As I see it, many of the best investment decisions take years to bear fruit. This long-term view means that the Fund will generally have a very low turnover ratio and reasonably low transaction costs. B-32 Q. Will you discuss your portfolio strategy during the 12-month period? A: I pursued two main strategies over the period. First, I sold a number of municipal bonds with short call dates. These bonds were purchased inexpensively several years ago and had performed well for the Fund. But with their call protection running out (at the call date, the issuer can refund the proceeds of the bond for cash at "par," the original offering price), the price appreciation potential for the bonds was limited. In their place, the Fund purchased municipal bonds with more attractive call features. This call protection strategy is meant to optimize the Fund's performance characteristics and has worked well over the long term. Second, during the 12-month period I purchased several par bonds for the Fund. Typically these bonds have limited appeal because - in terms of their price performance - they may have marginal upside and higher than normal downside should interest rates rise. However, the par bonds purchased during the period carried high yields and were very attractively priced. Several years ago, when California was in the midst of a fiscal crisis and issuing billions in debt in order to maintain services, I purchased a number of California bonds for the Fund because they were so inexpensive. Now that California's economy is performing much better, the state is beginning to make progress in dealing with its budget deficit. In light of this, two major ratings agencies upgraded California's debt in July 2005 and its bonds have been trading extremely strongly. Because the yields on the state's bonds have declined in the face of this progress, the Fund took profits on a number of California issues during the period. Q. How is the Fund positioned in terms of credit quality and diversification? A: Approximately 44% of the Fund's portfolio is rated AAA or the equivalent (the highest rating). In addition, the Fund is broadly diversified among 24 states and Puerto Rico. For the period, the Fund generally avoided purchasing any bonds with ratings lower than AAA. Purchasing lower quality bonds has been a popular strategy in the municipal marketplace in recent years, and "spreads" - or differences in yield between higher and lower quality municipal bonds - have narrowed considerably. At present, I do not believe investors are being adequately compensated in additional yield for the risk of buying lower quality bonds. Q. What is your outlook going forward? A: Every year brings unexpected events that move the market, but at present, long-term municipal bonds look very stable. Inflation figures seem modest, and it is hard to find economic factors or other trends that might change that. With an inverted yield curve in the Treasury market in December 2005 (where short-term rates were modestly higher than long-term rates), some have predicted an economic slowdown in 2006. If this occurs, it would be good news for long-term municipal bonds, because such slowdowns tend to reduce inflationary pressures. We will be monitoring the progress of the economy and markets over the course of the coming year, as well as the actions of the incoming Fed chairman Bernanke. We believe that Pioneer AMT-Free Municipal Fund continues to be a suitable vehicle for long-term investors seeking high income free from federal taxes. When interest rates rise, the prices of fixed income securities in the fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the fund will generally rise. Investments in the fund are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

B-37 PORTFOLIO MANAGEMENT DISCUSSION Pioneer Florida Tax Free Income Fund 1/31/06 Despite rising short-term interest rates during the last six months, shareholders in Pioneer Florida Tax Free Income Fund earned a positive return. In the following interview, David Eurkus, a Portfolio Manager and member of the Pioneer fixed-income team, discusses some of the factors that had an impact on the Fund's performance over the past six months. Q. How did the Fund perform during the six-month period ended January 31, 2006? A: During the six months, Class A shares of Pioneer Florida Tax Free Income Fund produced a total return of 0.85% at net asset value. The Fund underperformed its benchmark, the Merrill Lynch 1-12 Year Municipal Bond Index, which returned 1.16% for the same period. It also fell short of the average 0.90% return generated by the funds in the Florida Intermediate Municipal Debt Funds Category of Lipper, Inc., an independent monitor of mutual fund performance. At the end of the period, the 30-day SEC yield for Class A shares was 3.02% or a 4.65% taxable equivalent yield based on the maximum 35% federal tax bracket. The Fund had 42 issues with an average quality of AAA. Call 1-800-225-6292 or visit for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q. What was the investment environment like during the period? A: In an environment of relatively strong economic growth, the Federal Reserve continued to tighten monetary policy, boosting interest rates five times from 3.25% to 4.50% during the period. The net effect of the Fed's actions was a flattening of the yield curve, with short-term yields moving higher and longer-term yields remaining stable or declining slightly. In Florida, the rate of economic growth was greater than the national average, as solid gains in housing, personal income, tourism and international trade resulted in relatively low unemployment and added to the stability and strength of the Florida economy. Q. In this environment, what strategies did you use in managing the Fund? A: The Fund sought to balance the preservation of capital, while increasing current income that is exempt from federal income tax and Florida's intangible state personal property tax. Early in the period, most of the Fund's assets were invested in the short and intermediate part of the yield curve. Because we wanted to create a more diversified portfolio that would provide more income, we sold some short-maturity bonds, then selectively added longer-maturity bonds to the Fund. That had the effect of modestly extending the Fund's duration, or price sensitivity to interest-rate changes. It also boosted the Fund's income stream. When adding investments to the portfolio, we favored high-quality municipal securities in sectors that are essential to the growth of the Florida economy. These included health care and hospitals, public power, energy, transportation and education. We based our investment decisions on the fundamental attributes of each security, focusing on each bond's yield, liquidity, credit rating, call protection, issuer diversification and relative value. Q. What effect did the portfolio changes have on performance? A: To build upon my previous answer, Pioneer took over the assets from the AmSouth Florida Tax-Exempt Fund in late September 2005 when we sought a more flexible portfolio that could boost income by choosing longer-term bonds. That move enhanced performance. However, the Fund's relatively short duration at the beginning of the period resulted in a modest amount of underperformance. Q. What is your outlook for the next six months? A: The expansion in the national economy appears solid. Core inflation is relatively low, and longer-term inflation expectations appear to be contained. The Fed has indicated that it may be near the end of its rate-raising cycle, and so we may see fewer interest-rate hikes in the next several months. While we expect the overall business expansion in Florida to continue, it is likely that some sectors, such as housing, will slow down. The damage caused by the recent rash of hurricanes has presented the state and counties with big challenges. However, reconstruction of the damaged areas should continue to help solidify economic growth. In managing the Fund, we plan to remain fully invested and to maintain our diversification strategy among the broad range of Florida's municipal bond issuers. B-38 When interest rates rise, the prices of fixed income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. Investing primarily in the securities issued by Florida and its municipalities makes the Fund more vulnerable to unfavorable developments in Florida than are funds that invest in municipal securities of many states. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

B-43 PORTFOLIO MANAGEMENT DISCUSSION Pioneer Research Fund 12/31/05 In the following interview, John Peckham, U.S. Equity Research Coordinator and member of the Pioneer Research Fund team, discusses the factors that influenced performance for the twelve months ended December 31, 2005. Q. How did the US stock market perform in 2005? A: In a year that was notable for the variety of potential obstacles to market performance - including rising interest rates, a spike in energy prices, and September's Gulf Coast hurricanes - the U.S. market nonetheless produced solid returns on the strength of steady economic growth and impressive corporate earnings results. This generally positive environment, which lacked the speculative element that often characterizes sharply rising markets, provided a favorable backdrop for our bottom-up, research-based approach. Q. How did the Fund perform in relation to its benchmark and peer group? A: Class A shares of the Fund produced a total return of 7.20% at net asset value during the 12-month period ended December 31, 2005, outperforming the 4.91% of the Fund's benchmark, the S&P 500 Index. The Fund also beat the 4.84% average return of the 890 funds in the Fund's Lipper Large-Cap Core category during the annual period. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Naturally, past performance is no guarantee of future results. Having said that, we believe the Fund's strong showing in both 2004 and 2005 reflects the effectiveness of our investment process. We manage the portfolio with an emphasis on individual stock picking. We do not strive to predict the outlook for the economy, the market, or individual sectors, and we therefore keep the Fund's sector weightings as close to the S&P 500 as possible. The result is that the Fund's performance is almost entirely the result of the quality of our stock selection. And during 2005, we were successful in this endeavor: of the 25 subsectors we track, our stock picks outperformed the benchmark in 19. Q. What factors helped performance during the reporting period? A: We added value through our stock selection in the health care, energy and consumer discretionary sectors. In health care, three stocks provided outstanding returns for the Fund. Cubist Pharmaceuticals, a biotechnology company that developed a drug to treat hospital infections, returned over 80% for the year. Vertex Pharmaceuticals also climbed, as promising studies for its hepatitis drug led investors to boost their future earnings estimates for the company. And our position in IVAX Pharmaceuticals, a generic drug maker, was taken over by Israel's Teva Pharmaceuticals. Health care was a potentially challenging area in which to invest during 2005, and so we are pleased that we were able to add value in this sector. Energy was the strongest performing sector in the market during the year, as the rising prices of oil and gas led to robust profit growth for companies in the industry. A number of our stock picks did well, but the best performer was Premcor, an independent refiner that was purchased at a premium by Valero. Among large, diversified oil and gas companies, positive contributions came from ConocoPhillips and Occidental Petroleum, both of which outperformed. Weatherford International and Noble Corporation also benefited from the strength in their markets: equipment/services and drilling, respectively. It was relatively easy to find strong performing energy stocks during 2005, but we are gratified that our research process led us to invest in stocks that, as a group, outperformed the sector as a whole. Consumer discretionary stocks, which had a difficult year in 2005, were also a source of out performance for the Fund. In the automotive sector, we were helped by our avoidance of Ford and General Motors, both of which performed very poorly. The Fund instead owned Johnson Controls, an auto components manufacturer with a diversified customer base that provided exposure to the strong growth of the Asian car makers. In retail, our decision to own JC Penney and Target paid off as both executed well and posted gains in a year when retailers, as a group, provided only a flat return. B-44 Q. What elements of your positioning detracted from performance? A: Given the strength of our stock selection during the year, there were few meaningful detractors to performance. Our picks underperformed in six of the 25 industry subsectors, but in none of these was the shortfall meaningful. One detractor of note was Avon Products, which struggled with its U.S. and international sales efforts. Our performance was also disappointing in telecommunications services, where the Fund's investment in Vodafone lost ground due to the company's issues with increasing competition in Europe and its difficulty growing market share in Japan. Another notable misstep was our investment in Symantec, a software company that experienced lower-than-expected sales for its virus and security software. Q: Financials and technology are the two largest sectors in the S&P 500. How effective was your stock selection in these industries? A: In financials, our stock picks outperformed the financial stocks in the benchmark by a little more than two percentage points. The most significant drivers of performance were our positions in the investment banks/brokers Merrill Lynch and Goldman Sachs, both of which benefited from the strong market for initial public offerings as well as rising merger and acquisition activity. In bank stocks, where it was difficult to make money due to the interest rate environment, we benefited from our strategy of sticking to reasonably-priced stocks with diversified business mixes and yield curve exposures below the industry average. Such holdings included Bank of America, which was helped by the successful integration of Fleet Bank, as well as Wachovia Bank. In technology, we generated slight out performance. While Symantec hurt performance in software and services, we offset this through the out performance we generated in the semiconductor sector. Here, Texas Instruments benefited from the strong demand for the products in which its chips are used, including cell phones and high definition TVs. In hardware, the Fund's position in Hewlett-Packard performed well after the appointment of a new CEO raised hopes that its business will undergo the restructuring investors had been demanding. SanDisk, whose sales were boosted by the rapidly growing demand for flash memory, also made a positive contribution to Fund performance. Q. Do you have any closing thoughts for shareholders? A: While the year ahead is likely to be more volatile than 2005, we will continue to look past short-term market noise to identify fundamentally sound, reasonably valued companies. Given the favorable growth environment and the fact that the market as a whole is reasonably valued, we believe the environment will remain fertile for our bottom-up, research-driven investment process. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

B-49 PORTFOLIO MANAGEMENT DISCUSSION Pioneer Focused Equity Fund 1/31/06 In the following interview, portfolio managers Neil Wright, Janna Sampson and Peter Jankovskis discuss the factors that influenced Pioneer Focused Equity Fund's performance for the semiannual period ended January 31, 2006. Pioneer Focused Equity Fund was created through the reorganization of AmSouth Select Equity Fund on September 23, 2005. Q: Can you characterize the market environment for the Fund over the six-month period ended January 31, 2006? A: The semiannual period saw generally modest equity returns with the notable exception of energy and other commodity-related stocks. At the end of August 2005, Hurricane Katrina devastated the Gulf Coast, and this was followed a few weeks later by Rita. One of the results of this catastrophic hurricane season was a significant short-term disruption in the U.S. oil supply. That resulted in soaring energy prices, with a barrel of crude oil briefly topping the $70 mark, as compared to prices in the $30 range two years earlier. Other commodities, such as paper and metals, followed suit. As a result, commodity producing companies generally experienced substantial earnings increases during the period, while earnings - and share prices - in industries that rely on commodities in the manufacture or delivery of their products suffered from increased costs. Q. How did the Fund perform in this environment? A: Class A shares of the Fund returned (3.03)% at net asset value from July 31, 2005, through January 31, 2006, versus 4.67% for the Standard & Poor's 500 Index, the Fund's unmanaged benchmark. The Fund's long-term investment strategy of focusing on companies with strong brands constrained performance over a period in which market leadership was highly concentrated among commodity producers. In addition, many of the companies in our investment universe are heavy commodity consumers. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q. Can you outline the Fund's overall investment approach? A: Our investment universe is approximately 150 mid- and large capitalization companies with dominant market share positions that are supported by some barrier to entry such as a well-known brand name. Within our universe, we employ an actively managed, stock-by-stock approach to identify companies that we believe are trading at discounts to their long-term value. The result is a portfolio of 20 to 25 leading "market power" companies whose stock prices we believe are undervalued. We believe that a portfolio constructed in this fashion has the potential to outperform the broader market over a complete market cycle, with less volatility. Q. Can you discuss what helped and hurt performance of the Fund over the period? A: Unfortunately, the universe of companies from which we select investments was out of favor, and that was reflected in the Fund's results over the six months. We typically do not invest in the energy sector, and during the period we had no exposure to energy, which was by far the best performing sector. In addition, we made a decision to avoid the financial sector because we thought the Federal Reserve would continue to raise rates on the short end, and we expected longer-term rates to rise along with commodity prices. However, long-term rates were stable as the market did not perceive inflation as a threat, and in retrospect exposure to financials would have helped performance. Because one of our principal areas of focus is on companies with strong brands, we are generally overweighted versus the broad market in the consumer-oriented sectors, which underperformed during the semiannual period. At the end of January, the consumer discretionary and consumer staples sectors comprised over 36% and 21%, respectively, of the Fund. Our biggest holding in this area and one of our better performers was McDonald's, a bellwether consumer discretionary stock. McDonald's managed to grow sales and maintain strong earnings on the basis of well received new products and promotions. In addition, McDonald's has taken steps to reduce its paper costs, by reducing the size of the containers used to deliver food to consumers. A number of holdings were affected more decisively during the period by higher paper costs, including newspaper publisher Tribune. A tepid advertising environment also contributed to weaker results for publishers. Among consumer staples, Kimberly Clark was hit especially hard by the increased cost of paper. The company relies heavily on sales of paper-based products such as diapers and facial tissues, and recently sold its paper mill, making its earnings more subject to fluctuations in the price of that commodity. In B-50 addition, Kimberly Clark incurred significant research costs during the period, which acted to lower short-term earnings, but which we believe will serve the company well in the longer run. The Fund is also overweight the industrial sector, which stood at over 21% of assets at the end of January. The Fund's largest holding in this area is Automatic Data Processing (ADP) the leading provider of payroll processing services to employers. We expected the company's shares to perform well given both the growth in U.S. employment and rising short-term interest rates, which provide a boost to earnings on cash held by ADP pending its disbursement to employees of its client companies. However, concerns about economic growth and the sustainability of recent employment gains held back the performance of ADP's stock during the period. As we are long-term investors in a fairly concentrated number of companies, turnover in the portfolio is typically low. The biggest change among our holdings during the period was the elimination of Wal-Mart Stores from the portfolio. Our decision was made in view of a change in banking regulations that took effect in January of 2006 and that has resulted in a doubling of minimum credit card payments for millions of consumers. While the change has not yet been reflected in the company's business results or share price performance, we believe it has the potential to hurt Wal-Mart more than its peers. Q. How are you positioning the Fund going forward? A: We expect energy prices and commodity prices in general to moderate, giving the companies on which we focus an opportunity gradually to raise prices and restore profitability. Historically, the Fund's universe of "market power" companies has traded at a premium to the overall market based on such valuation measures as price-earnings ratios, which indicate how much investors are willing to pay per dollar of a company's earnings. However, many of the companies we hold are currently priced at below-market price earnings ratios and dramatically below their long-term average valuations. We believe the Fund is well positioned for the next phase of the market cycle, even if commodity prices remain near their current levels. The biggest risk to this outlook is a sharp increase in energy prices during the first quarter of 2006, which we do not view as likely. Going forward, we will continue to use intensive fundamental research to target leading companies benefiting from competitive barriers that help protect their market shares and profits, with a focus on those companies that are selling at reasonable valuations. Our goal remains to outperform the broader market over the long term, with less short-term volatility. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of the opinion of Fund management as of the date of this report. These statements should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Expense adjustments are based on the higher or lower expense structure (e.g., custodian fees, printing fees and other expenses) of the combined fund. (b) Expense adjustments conform to the combined fund's contracts with affiliated parties. Expense adjustments are based on the higher or lower contractual expense structure (e.g., transfer agency fees, Rule 12b-1 distribution and service fees, and administrative expenses), as well as the expense characteristics of the combined fund and its share classes (e.g., net assets, average shareholder account size and number of shareholder accounts), which differs from those of each fund on an uncombined basis and also differs from any predecessor fund. (c) Includes costs of the reorganization. (d) The predecessor fund to Pioneer Florida Tax Free Income Fund charged a shareholder servicing (non-Rule 12b-1) fee that ranged from 0.15% up to 0.25% of that predecessor fund's average daily net assets, depending on the share class. After the closing of the reorganization on September 23, 2005, the predecessor fund's shareholder servicing fees terminated and Pioneer Florida Tax Free Income Fund adopted plans of distribution pursuant to Rule 12b-1 ("Rule 12b-1 Plans") with respect to its Class A, Class B and Class C shares providing for fees payable at the annual rates of 0.25%, 1.00% and 1.00% of the fund's average daily net assets attributable to these respective classes. Pursuant to the Pioneer Rule 12b-1 Plans, each fund's Class B and Class C shares pay a combined distribution and service fee of 1.00%, of which 0.75% is paid for distribution services and 0.25% is paid for shareholder services. The pro forma adjustments reflect the Rule 12b-1 Plans of the combined fund. See accompanying notes to pro forma financial statements.

Security is exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be resold normally to qualified institutional buyers in a transaction exempt from registration. (a) No adjustments are shown to the unaudited pro forma combined schedule of investments due to the fact that upon consummation of the merger no securities would need to be sold in order for Pioneer AMT-Free Municipal Fund to comply with its prospectus restrictions. The foregoing sentence shall not restrict in any way the ability of the investment adviser of the funds from buying or selling securities in the normal course of such fund's business and operations. (b) Includes costs of the reorganization. The accompanying notes are an integral part of these financial statements. Pioneer AMT-Free Municipal Fund PRO FORMA NOTES TO COMBINING FINANCIAL STATEMENTS 12/31/05 (Unaudited) 1. Description of the Fund Pioneer AMT-Free Municipal Fund (the Fund) is one of eight series of portfolios comprising Pioneer Series Trust II, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund is the successor to the Safeco Municipal Bond Fund, Inc. Safeco Municipal Bond Fund transferred all of its net assets in exchange for the Fund's Investor Class shares on December 10, 2004 pursuant to an agreement and plan of reorganization (the "reorganization" which was approved by the shareholders of Safeco Municipal Bond Fund on December 8, 2004). The Fund had no assets or liabilities prior to the reorganization. Accordingly, the reorganization, which was a tax-free exchange, had no effect on the Fund's operations. The investment objective of the Fund is to seek a high level of current income exempt from federal income tax as is consistent with the relative stability of capital. The Trustees have authorized the issuance of five classes of shares of the Fund. The Fund offers five classes of shares designated as Class A, Class B, Class C, Class Y and Investor Class shares. The Fund is not offering additional Investor Class shares except in connection with the reinvestment of dividends on the Fund's outstanding Investor Class shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and have equal rights to voting, redemptions, dividends and liquidations, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B and Class C shareowners, respectively. There is no distribution plan for Class Y and Investor Class shares. 2. Basis of Combination The accompanying pro forma combining financial statements, and related notes, are presented to show the effect of the proposed acquisition (the "acquisition") of Pioneer Florida Tax Free Income Fund by the Fund, as if such acquisition had taken place as of December 31, 2005. Under the terms of an Agreement and Plan of Reorganization (the "Reorganization") between these two Funds, the combination of the Fund and Florida Tax Free Income Fund will be treated as a tax-free business combination and accordingly will be accounted for by a method of accounting for tax-free mergers of investment companies. The acquisition will be accomplished by an acquisition of the net assets of Pioneer Florida Tax Free Income Fund in exchange for shares of the Fund at their net asset values. The accompanying schedules of investments, statements of assets and liabilities and the related statements of operations of the Fund and Pioneer Florida Tax Free Income Fund have been combined as of and for the most recent fiscal year ended December 31, 2005. Following the acquisition, the Fund will be the accounting survivor. The Advisor has agreed to pay 50% of the expenses associated with the reorganizations, and AMT-Free Municipal Fund and Florida Tax Free Income Fund will equally bear the remaining costs of the reorganization. These costs are reflected in the proforma financial statements. These pro forma financial statements and related notes should be read in conjunction with the financial statements of the Fund and Pioneer Florida Tax Free Income Fund included in their annual reports to shareowners dated December 31, 2005 and July 31, 2005, respectively. Adjustments have been made to eliminate duplicate expenses that would not have been incurred if the merger had taken place on December 31, 2005, and to reflect the expenses for contractual rates that will exist after the merger, based on actual contract rates that exist for the AMT-Free Municipal Fund at December 31, 2005. 3. Security Valuation Security transactions are recorded as of trade date. Securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which there are no other readily available market quotations are valued at their fair values as determined by, or under the direction of the Board of Trustees. The Fund also may use the fair value of a security including a non-U.S. security when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. Temporary cash investments are valued at amortized cost. Discount and premium on debt securities are accreted or amortized, respectfully daily into interest income on a yield-to-maturity basis with a corresponding increase or decrease in the cost basis of the security. Interest income is recorded on the accrual basis. 4. Capital Shares The pro forma net asset value per share assumes the issuance of shares of the Fund that would have been issued at December 31, 2005, in connection with the proposed acquisition. The number of shares assumed to be issued is equal to the net asset value of shares of Pioneer Florida Tax Free Income Fund, as of December 31, 2005, divided by the net asset value per share of the Fund's shares as of December 31, 2005. The pro forma number of shares outstanding, by class, for the combined Fund consists of the following at December 31, 2005: Shares of Additional Shares Total Outstanding The Fund Assumed Issued Shares Class of Shares Pre-Combination In Reorganization Post-Combination - ---------------------------------------------------------------------- Class A 1,134,813 262,375 1,387,188 - ---------------------------------------------------------------------- Class B 168,335 135,053 303,338 - ---------------------------------------------------------------------- Class C 84,265 700 84,965 - ---------------------------------------------------------------------- Investor 32,938,017 - 32,938,017 - ---------------------------------------------------------------------- Class Y 2,909,177 2,909,177 - ---------------------------------------------------------------------- 5. Federal Income Taxes Each Fund has elected to be taxed as a "regulated investment company" under the Internal Revenue Code. After the acquisition, it will continue to be the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The identified cost of investments for these Funds is substantially the same for both financial and federal income tax purposes. The cost of investments will remain unchanged for the combined Fund. PART C OTHER INFORMATION PIONEER SERIES TRUST II (on behalf of its series, Pioneer AMT-Free Municipal Fund) ITEM 15.

(*) Filed herewith as Exhibit A to the Proxy Statement and Prospectus included as Part A of this Registration Statement. (**) Filed herewith. ITEM 17. UNDERTAKINGS. (1) The undersigned Registrant agrees that prior to any public reoffering of the securities registered through the use of a prospectus which is part of this Registration Statement by any person or party which is deemed to be an underwriter within the meaning of Rule 145(c) of the 1933 Act, the reoffering prospectus will contain the information called for by the applicable registration form for the reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (2) The undersigned Registrant agrees that every prospectus that is filed under paragraph (1) above will be filed as part of an amendment to the Registration Statement and will not be used until the amendment is effective, and that, in determining any liability under the 1933 Act, each post-effective amendment shall be deemed to be a new registration statement for the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering of them. (3) The undersigned Registrant agrees that it shall file a final executed version of the legal and consent opinion as to tax matters as an exhibit to the subsequent post-effective amendment to its registration statement on Form N-14 filed with the SEC upon the consummation of the reorganization contemplated by this Registration Statement on Form N-14. (4) Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
